27
Mark Dickinsoncbb62742009-12-27 15:09:50 +000028- Issue #1811: improve accuracy and cross-platform consistency for
29 true division of integers: the result of a/b is now correctly
30 rounded for ints a and b (at least on IEEE 754 platforms), and in
31 particular does not depend on the internal representation of an int.
32
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000033- Issue #6834: replace the implementation for the 'python' and 'pythonw'
34 executables on OSX.

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

R. David Murray445448c2009-12-20 17:28:31 +0000612- Issue #7376: instead of running a self-test (which was failing) when called
613 with no arguments, doctest.py now gives a usage message.
614
R. David Murrayef1992b2009-12-16 15:19:27 +0000615- Issue #7396: fix regrtest -s, which was broken by the -j enhancement.
616
R. David Murray596da442009-12-14 23:06:11 +0000617- Issue #7498: test_multiprocessing now uses test.support.find_unused_port
R. David Murray83396232009-12-14 22:45:15 +0000618 instead of a hardcoded port number in test_rapid_restart.
619
R. David Murrayba311052009-12-04 00:09:14 +0000620- Issue #7431: use TESTFN in test_linecache instead of trying to create a
621 file in the Lib/test directory, which might be read-only for the
622 user running the tests.
623
R. David Murray35768ad2009-11-15 00:23:21 +0000624- Issue #7324: add a sanity check to regrtest argument parsing to
625 catch the case of an option with no handler.
626
R. David Murray7dc72cc2009-11-14 16:13:02 +0000627- Issue #7312: Add a -F flag to run the selected tests in a loop until
628 a test fails. Can be combined with -j.
629
Antoine Pitrou060cee22009-11-13 16:29:04 +0000630- Issue #6551: test_zipimport could import and then destroy some modules of
631 the encodings package, which would make other tests fail further down
632 the road because the internally cached encoders and decoders would point
633 to empty global variables.
634
Antoine Pitrou941ee882009-11-11 20:59:38 +0000635- Issue #7295: Do not use a hardcoded file name in test_tarfile.
636
Antoine Pitrou557934f2009-11-06 22:41:14 +0000637- Issue #7270: Add some dedicated unit tests for multi-thread synchronization

639
Brett Cannoncfed0292009-11-05 01:26:57 +0000640- Issue #7248 (part 2): Use a unique temporary directory for importlib source
641 tests instead of tempfile.tempdir. This prevents the tests from sharing state
642 between concurrent executions on the same system.
643
Brett Cannon0ae45112009-11-05 01:17:22 +0000644- Issue #7248: In importlib.test.source.util a try/finally block did not make
645 sure that some referenced objects actually were created in the block before
646 calling methods on the object.
647
Antoine Pitrou65c9c642009-10-30 17:25:12 +0000648- Issue #7222: Make thread "reaping" more reliable so that reference
649 leak-chasing test runs give sensible results. The previous method of
650 reaping threads could return successfully while some Thread objects were
651 still referenced. This also introduces a new private function:
652 :func:`_thread._count()`.
653
R. David Murray27144602009-10-19 15:26:16 +0000654- Issue #7151: fixed regrtest -j so that output to stderr from a test no
655 longer runs the risk of causing the worker thread to fail.
656
Antoine Pitrou4de39cd2009-10-10 21:08:31 +0000657- Issue #7055: test___all__ now greedily detects all modules which have an
658 __all__ attribute, rather than using a hardcoded and incomplete list.
659
R. David Murray0bc11ae2009-10-18 22:18:17 +0000660- Issue #7058: Added save/restore for things like sys.argv and cwd to

662 and a new section in the summary report at the end.

665
Brett Cannon3c273842009-07-20 00:14:29 +0000666- Fixed tests in importlib.test.source.test_abc_loader that were masking
667 the proper exceptions that should be raised for missing or improper code

920- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
921 tests on darwin even when the OS was installed on a case-sensitive
922 filesystem. Also fixed tests that should not be run when
923 sys.dont_write_bytecode is true.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000926What's New in Python 3.1 beta 1?
927================================

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000930
931Core and Builtins
932-----------------
933
Mark Dickinson865e01a2009-05-07 16:37:01 +0000934- Issue #5914: Add new C API function PyOS_string_to_double, and
935 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
936
Eric Smith741191f2009-05-06 13:08:15 +0000937- Issue #3382: float.__format__, complex.__format__, and %-formatting
938 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
939 affects nan -> NAN and inf -> INF.
940
Mark Hammond5a607a32009-05-06 08:04:54 +0000941- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
942 in all operations, including splitdrive, split, etc. splitunc() now issues
943 a PendingDeprecation warning.
944
Eric Smith63376222009-05-05 14:04:18 +0000945- Issue #5920: For float.__format__, change the behavior with the
946 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
947 to be like 'g' but with at least one decimal point and with a
948 default precision of 12. Previously, the behavior the same but with
949 a default precision of 6. This more closely matches str(), and
950 reduces surprises when adding alignment flags to the empty
951 presentation type. This also affects the new complex.__format__ in
952 the same way.
953
Martin v. Löwis011e8422009-05-05 04:43:17 +0000954- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
955
R. David Murrayb18500d2009-05-04 22:59:07 +0000956- Issue #5890: in subclasses of 'property' the __doc__ attribute was
957 shadowed by classtype's, even if it was None. property now
958 inserts the __doc__ into the subclass instance __dict__.
959
Antoine Pitrou244651a2009-05-04 18:56:13 +0000960- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
961 sequences. Patch by Nick Barnes and Victor Stinner.
962
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000963- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000964
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000965- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
966 received a new method, detach(). detach() disconnects the underlying stream
967 from the buffer or text IO and returns it.
968
Mark Dickinson33841c32009-05-01 15:37:04 +0000969- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
970 floats with absolute value over 1e50. Also remove length
971 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
972 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000973
Eric Smith741191f2009-05-06 13:08:15 +0000974- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000975 format(complex(1, 2./3), '.5') now produces a sensible result.
976
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000977- Issue #5864: Fix empty format code formatting for floats so that it
978 never gives more than the requested number of significant digits.
979
Eric Smith6dc46f52009-04-27 20:39:49 +0000980- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
981 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
982
Eric Smithcc32a112009-04-26 21:35:14 +0000983- Issue #5835: Deprecate PyOS_ascii_formatd.
984
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000985- Issue #4971: Fix titlecase for characters that are their own
986 titlecase, but not their own uppercase.
987
Benjamin Peterson193152c2009-04-25 01:08:45 +0000988- Issue #5283: Setting __class__ in __del__ caused a segfault.
989
Mark Dickinsonad476da2009-04-23 19:14:16 +0000990- Issue #5816: complex(repr(z)) now recovers z exactly, even when
991 z involves nans, infs or negative zeros.
992
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000993- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000994
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000995- Issue #1869 (and many duplicates): make round(x, n) correctly
996 rounded for a float x, by using the decimal <-> binary conversions
997 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
998 consistently agrees with format(x, '.2f').
999
Benjamin Petersonae937c02009-04-18 20:54:08 +00001000- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1001 some builtin types.
1002
Eric Smith0923d1d2009-04-16 20:16:10 +00001003- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1004
Eric Smith35e84722009-04-16 20:21:28 +00001005- Issue #5515: str.format() type 'n' combined with commas and leading
1006 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001007
1008- Implement PEP 378, Format Specifier for Thousands Separator, for
1009 floats.
1010
Mark Dickinson3370cce2009-04-17 22:40:53 +00001011- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001012 1e11, not 1e12. This avoids printing 13 significant digits in
1013 situations where only 12 of them are correct. Example problem
1014 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1015 long time.)
1016
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001017- Issue #1580: On most platforms, use a 'short' float repr: for a
1018 finite float x, repr(x) now outputs a string based on the shortest
1019 sequence of decimal digits that rounds to x. Previous behaviour was
1020 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001021 Another minor difference is that the new repr switches to
1022 exponential notation at 1e16 instead of the previous 1e17; this
1023 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001024
1025 There's a new sys attribute sys.float_repr_style, which takes
1026 the value 'short' to indicate that we're using short float repr,
1027 and 'legacy' if the short float repr isn't available for one
1028 reason or another.
1029
1030 The float repr change involves incorporating David Gay's 'perfect
1031 rounding' code into the Python core (it's in Python/dtoa.c). As a
1032 secondary consequence, all string-to-float and float-to-string
1033 conversions (including all float formatting operations) will be
1034 correctly rounded on these platforms.
1035
1036 See issue 1580 discussions for details of platforms for which
1037 this change does not apply.
1038
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001039- Issue #5759: float() didn't call __float__ on str subclasses.
1040
Georg Brandlabc38772009-04-12 15:51:51 +00001041- The string.maketrans() function is deprecated; there is a new static method
1042 maketrans() on the bytes and bytearray classes. This removes confusion about
1043 the types string.maketrans() is supposed to work with, and mirrors the
1044 methods available on the str class.
1045
R. David Murraydc6da8a2009-04-09 22:16:43 +00001046- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1047 its clarity and its speed.
1048
Matthias Klose091c7b12009-04-07 13:24:27 +00001049- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1050 to avoid compiler warnings.
1051
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001052- Issue #3739: The unicode-internal encoder now reports the number of characters
1053 consumed like any other encoder (instead of the number of bytes).

1068
Vinay Sajipaffbd872009-06-11 10:11:47 +00001069- Issue #5940: distutils.command.build_clib.check_library_list was not doing

1211 untrackable objects are not tracked by the garbage collector. This can
1212 reduce the size of collections and therefore the garbage collection overhead
1213 on long-running programs, depending on their particular use of datatypes.

1334 rotating the object pointer by 4 bits to the right.
1335
Mark Dickinson87ec0852009-02-09 17:15:59 +00001336- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1337 it now forces its argument to double before testing for infinity.
1338
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001339- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001348
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001349- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001350 were suppressing all exceptions. These include list() and bytearray().
1351
Mark Dickinson1124e712009-01-28 21:25:58 +00001352- Issue #4707: round(x, n) now returns an integer if x is an integer.
1353 Previously it returned a float.
1354
Antoine Pitroub52ec782009-01-25 16:34:23 +00001355- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1356 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1357 evaluation loop is compiled with a new dispatch mechanism which gives
1358 speedups of up to 20%, depending on the system, on various benchmarks.
1359
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001360- Issue #4874: Most builtin decoders now reject unicode input.

1366
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001367- Issue #4838: When a module is deallocated, free the memory backing the
1368 optional module state data.
1369
Mark Dickinson8055afd2009-01-17 10:04:45 +00001370- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1371 type to (void *).
1372
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001373- Issue #4935: The overflow checking code in the expandtabs() method common
1374 to str, bytes and bytearray could be optimized away by the compiler, letting
1375 the interpreter segfault instead of raising an error.
1376
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001377- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1378 __next__ method.
1379
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001380- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1381 function no longer attempt to call the __long__ slot to convert an object
1382 to an integer. Only the __int__ and __trunc__ slots are examined.
1383
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001384- Issue #4893: Use NT threading on CE.
1385

1387
Antoine Pitrouab868312009-01-10 15:40:25 +00001388- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1389 common cases are optimized thanks to a dedicated fast path and a moderate
1390 amount of loop unrolling.
1391
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001392- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1393 collecting the oldest generation) so that allocating lots of objects without
1394 destroying them does not show quadratic performance. Based on a proposal by
1395 Martin von Löwis at
1396 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1397
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001398- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001399 having been closed (for instance, a read() call could return some
1400 previously buffered data). Patch by Dmitry Vasiliev.
1401
Antoine Pitrou05608432009-01-09 18:53:14 +00001402- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1403 flag to work properly. Furthermore, when specifying -u, the text stdout
1404 and stderr streams have line-by-line buffering enabled (the default being
1405 to buffer arbitrary chunks of data).
1406
Raymond Hettinger35631532009-01-09 03:58:09 +00001407- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1408 instead of ints (reducing its size from 4 to 8 times thereby reducing
1409 Python's overall memory).
1410
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001411- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1412 an existing .py counterpart, override the co_filename attributes of all
1413 code objects if the original filename is obsolete (which can happen if the
1414 file has been renamed, moved, or if it is accessed through different paths).
1415 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1416
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001417- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1418 one byte. Also fixes the meaning of len() so that it returns the number of
1419 items, rather than the size in bytes.
1420
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001421- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1422
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001423- Issue #4747: When the terminal does not use utf-8, executing a script with
1424 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1425
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001426- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001427 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001428
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001429- Issue #3680: Reference cycles created through a dict, set or deque iterator
1430 did not get collected.
1431
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001432- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1433 where the tp_hash and tp_dict slots are both NULL.
1434
Georg Brandlccc47b62008-12-28 11:44:14 +00001435- Issue #4759: None is now allowed as the first argument of
1436 bytearray.translate(). It was always allowed for bytes.translate().
1437
Skip Montanaro80072cb2008-12-23 03:51:14 +00001438- Added test case to ensure attempts to read from a file opened for writing
1439 fail.

1448 unreachable. Original patch by Neil Schemenauer.
1449

1451
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001452- Issue #2173: When getting device encoding, check that return value of
1453 nl_langinfo is not the empty string. This was causing silent build
1454 failures on OS X.
1455
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001456- Issue #4597: Fixed several opcodes that weren't always propagating
1457 exceptions.
1458
1459- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001460 context manager returns a value that cannot be converted to a bool.
1461
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001462- Issue #4445: Replace "sizeof(PyBytesObject)" with
1463 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1464 bytes instances. On a typical machine this saves 3 bytes of memory
1465 (on average) per allocation of a bytes instance.
1466
Christian Heimesa872de52008-12-05 08:26:55 +00001467- Issue #4533: File read operation was dreadfully slow due to a slowly
1468 growing read buffer. Fixed by using the same growth rate algorithm as
1469 Python 2.x.
1470
Antoine Pitrou5504e892008-12-06 21:27:53 +00001471- Issue #4509: Various issues surrounding resize of bytearray objects to
1472 which there are buffer exports (e.g. memoryview instances).
1473
Georg Brandlf9734072008-12-07 15:30:06 +00001474- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1475 method on file objects with closefd=False. The file descriptor is still
1476 kept open but the file object behaves like a closed file. The ``FileIO``
1477 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00001479- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1487 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1488 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1489 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou88909542009-06-29 13:54:42 +00002091- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2092 regression tests in parallel, shortening the total runtime.
2093
Guilherme Polo2a998fa2009-06-21 17:40:07 +00002094- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2095 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2096 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2097 skip the tests if DISPLAY is defined but can't be used.
2098
R. David Murraya21e4ca2009-03-31 23:16:50 +00002099- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002100 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002101 from test support, which does the conversion.
2102
Guilherme Polo9de29af2009-01-28 20:40:48 +00002103- Issue #5083: New 'gui' resource for regrtest.
