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.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000930What's New in Python 3.1 beta 1?
931================================

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000933*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000934
935Core and Builtins
936-----------------
937
Mark Dickinson865e01a2009-05-07 16:37:01 +0000938- Issue #5914: Add new C API function PyOS_string_to_double, and
939 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
940
Eric Smith741191f2009-05-06 13:08:15 +0000941- Issue #3382: float.__format__, complex.__format__, and %-formatting
942 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
943 affects nan -> NAN and inf -> INF.
944
Mark Hammond5a607a32009-05-06 08:04:54 +0000945- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
946 in all operations, including splitdrive, split, etc. splitunc() now issues
947 a PendingDeprecation warning.
948
Eric Smith63376222009-05-05 14:04:18 +0000949- Issue #5920: For float.__format__, change the behavior with the
950 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
951 to be like 'g' but with at least one decimal point and with a
952 default precision of 12. Previously, the behavior the same but with
953 a default precision of 6. This more closely matches str(), and
954 reduces surprises when adding alignment flags to the empty
955 presentation type. This also affects the new complex.__format__ in
956 the same way.
957
Martin v. Löwis011e8422009-05-05 04:43:17 +0000958- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
959
R. David Murrayb18500d2009-05-04 22:59:07 +0000960- Issue #5890: in subclasses of 'property' the __doc__ attribute was
961 shadowed by classtype's, even if it was None. property now
962 inserts the __doc__ into the subclass instance __dict__.
963
Antoine Pitrou244651a2009-05-04 18:56:13 +0000964- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
965 sequences. Patch by Nick Barnes and Victor Stinner.
966
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000967- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000968
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000969- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
970 received a new method, detach(). detach() disconnects the underlying stream
971 from the buffer or text IO and returns it.
972
Mark Dickinson33841c32009-05-01 15:37:04 +0000973- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
974 floats with absolute value over 1e50. Also remove length
975 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
976 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000977
Eric Smith741191f2009-05-06 13:08:15 +0000978- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000979 format(complex(1, 2./3), '.5') now produces a sensible result.
980
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000981- Issue #5864: Fix empty format code formatting for floats so that it
982 never gives more than the requested number of significant digits.
983
Eric Smith6dc46f52009-04-27 20:39:49 +0000984- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
985 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
986
Eric Smithcc32a112009-04-26 21:35:14 +0000987- Issue #5835: Deprecate PyOS_ascii_formatd.
988
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000989- Issue #4971: Fix titlecase for characters that are their own
990 titlecase, but not their own uppercase.
991
Benjamin Peterson193152c2009-04-25 01:08:45 +0000992- Issue #5283: Setting __class__ in __del__ caused a segfault.
993
Mark Dickinsonad476da2009-04-23 19:14:16 +0000994- Issue #5816: complex(repr(z)) now recovers z exactly, even when
995 z involves nans, infs or negative zeros.
996
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000997- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000998
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000999- Issue #1869 (and many duplicates): make round(x, n) correctly
1000 rounded for a float x, by using the decimal <-> binary conversions
1001 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1002 consistently agrees with format(x, '.2f').
1003
Benjamin Petersonae937c02009-04-18 20:54:08 +00001004- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1005 some builtin types.
1006
Eric Smith0923d1d2009-04-16 20:16:10 +00001007- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1008
Eric Smith35e84722009-04-16 20:21:28 +00001009- Issue #5515: str.format() type 'n' combined with commas and leading
1010 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001011
1012- Implement PEP 378, Format Specifier for Thousands Separator, for
1013 floats.
1014
Mark Dickinson3370cce2009-04-17 22:40:53 +00001015- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001016 1e11, not 1e12. This avoids printing 13 significant digits in
1017 situations where only 12 of them are correct. Example problem
1018 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1019 long time.)
1020
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001021- Issue #1580: On most platforms, use a 'short' float repr: for a
1022 finite float x, repr(x) now outputs a string based on the shortest
1023 sequence of decimal digits that rounds to x. Previous behaviour was
1024 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001025 Another minor difference is that the new repr switches to
1026 exponential notation at 1e16 instead of the previous 1e17; this
1027 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001028
1029 There's a new sys attribute sys.float_repr_style, which takes
1030 the value 'short' to indicate that we're using short float repr,
1031 and 'legacy' if the short float repr isn't available for one
1032 reason or another.
1033
1034 The float repr change involves incorporating David Gay's 'perfect
1035 rounding' code into the Python core (it's in Python/dtoa.c). As a
1036 secondary consequence, all string-to-float and float-to-string
1037 conversions (including all float formatting operations) will be
1038 correctly rounded on these platforms.
1039
1040 See issue 1580 discussions for details of platforms for which
1041 this change does not apply.
1042
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001043- Issue #5759: float() didn't call __float__ on str subclasses.
1044
Georg Brandlabc38772009-04-12 15:51:51 +00001045- The string.maketrans() function is deprecated; there is a new static method
1046 maketrans() on the bytes and bytearray classes. This removes confusion about
1047 the types string.maketrans() is supposed to work with, and mirrors the
1048 methods available on the str class.
1049
R. David Murraydc6da8a2009-04-09 22:16:43 +00001050- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1051 its clarity and its speed.
1052
Matthias Klose091c7b12009-04-07 13:24:27 +00001053- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1054 to avoid compiler warnings.
1055
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001056- Issue #3739: The unicode-internal encoder now reports the number of characters
1057 consumed like any other encoder (instead of the number of bytes).

1226 --enable-big-digits option to configure, which overrides the
1227 default. Add sys.int_info structseq to provide information about
1228 the internal format.

Mark Dickinson87ec0852009-02-09 17:15:59 +00001340- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1341 it now forces its argument to double before testing for infinity.
1342
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001343- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001352
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001353- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001354 were suppressing all exceptions. These include list() and bytearray().
1355
Mark Dickinson1124e712009-01-28 21:25:58 +00001356- Issue #4707: round(x, n) now returns an integer if x is an integer.
1357 Previously it returned a float.
1358
Antoine Pitroub52ec782009-01-25 16:34:23 +00001359- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1360 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1361 evaluation loop is compiled with a new dispatch mechanism which gives
1362 speedups of up to 20%, depending on the system, on various benchmarks.
1363
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001364- Issue #4874: Most builtin decoders now reject unicode input.

1370
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001371- Issue #4838: When a module is deallocated, free the memory backing the
1372 optional module state data.
1373
Mark Dickinson8055afd2009-01-17 10:04:45 +00001374- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1375 type to (void *).
1376
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001377- Issue #4935: The overflow checking code in the expandtabs() method common
1378 to str, bytes and bytearray could be optimized away by the compiler, letting
1379 the interpreter segfault instead of raising an error.
1380
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001381- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1382 __next__ method.
1383
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001384- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1385 function no longer attempt to call the __long__ slot to convert an object
1386 to an integer. Only the __int__ and __trunc__ slots are examined.
1387
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001388- Issue #4893: Use NT threading on CE.
1389

1391
Antoine Pitrouab868312009-01-10 15:40:25 +00001392- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1393 common cases are optimized thanks to a dedicated fast path and a moderate
1394 amount of loop unrolling.
1395
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001396- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1397 collecting the oldest generation) so that allocating lots of objects without
1398 destroying them does not show quadratic performance. Based on a proposal by
1399 Martin von Löwis at
1400 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1401
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001402- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001403 having been closed (for instance, a read() call could return some
1404 previously buffered data). Patch by Dmitry Vasiliev.
1405
Antoine Pitrou05608432009-01-09 18:53:14 +00001406- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1407 flag to work properly. Furthermore, when specifying -u, the text stdout
1408 and stderr streams have line-by-line buffering enabled (the default being
1409 to buffer arbitrary chunks of data).
1410
Raymond Hettinger35631532009-01-09 03:58:09 +00001411- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1412 instead of ints (reducing its size from 4 to 8 times thereby reducing
1413 Python's overall memory).
1414
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001415- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1416 an existing .py counterpart, override the co_filename attributes of all
1417 code objects if the original filename is obsolete (which can happen if the
1418 file has been renamed, moved, or if it is accessed through different paths).
1419 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1420
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001421- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1422 one byte. Also fixes the meaning of len() so that it returns the number of
1423 items, rather than the size in bytes.
1424
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001425- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1426
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001427- Issue #4747: When the terminal does not use utf-8, executing a script with
1428 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1429
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001430- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001431 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001432
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001433- Issue #3680: Reference cycles created through a dict, set or deque iterator
1434 did not get collected.
1435
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001436- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1437 where the tp_hash and tp_dict slots are both NULL.
1438
Georg Brandlccc47b62008-12-28 11:44:14 +00001439- Issue #4759: None is now allowed as the first argument of
1440 bytearray.translate(). It was always allowed for bytes.translate().
1441
Skip Montanaro80072cb2008-12-23 03:51:14 +00001442- Added test case to ensure attempts to read from a file opened for writing
1443 fail.
1444
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001445- Issue #3106: Speedup some comparisons (str/str and int/int).

1449
Antoine Pitrou621601a2008-12-17 23:18:19 +00001450- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1451 print elapsed times, not only when some objects are uncollectable /
1452 unreachable. Original patch by Neil Schemenauer.
1453
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001454- Issue #3439: Add a bit_length method to int.
1455
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001456- Issue #2173: When getting device encoding, check that return value of
1457 nl_langinfo is not the empty string. This was causing silent build
1458 failures on OS X.
1459
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001460- Issue #4597: Fixed several opcodes that weren't always propagating
1461 exceptions.
1462
1463- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001464 context manager returns a value that cannot be converted to a bool.
1465
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001466- Issue #4445: Replace "sizeof(PyBytesObject)" with
1467 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1468 bytes instances. On a typical machine this saves 3 bytes of memory
1469 (on average) per allocation of a bytes instance.
1470
Christian Heimesa872de52008-12-05 08:26:55 +00001471- Issue #4533: File read operation was dreadfully slow due to a slowly
1472 growing read buffer. Fixed by using the same growth rate algorithm as
1473 Python 2.x.
1474
Antoine Pitrou5504e892008-12-06 21:27:53 +00001475- Issue #4509: Various issues surrounding resize of bytearray objects to
1476 which there are buffer exports (e.g. memoryview instances).
1477
Georg Brandlf9734072008-12-07 15:30:06 +00001478- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1479 method on file objects with closefd=False. The file descriptor is still
1480 kept open but the file object behaves like a closed file. The ``FileIO``
1481 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00001483- Issue #4569: Interpreter crash when mutating a memoryview with an item size

Walter Dörwaldc1651a02009-05-03 22:55:55 +00001490- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1491 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1492 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1493 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou88909542009-06-29 13:54:42 +00002095- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2096 regression tests in parallel, shortening the total runtime.

Guilherme Polo2a998fa2009-06-21 17:40:07 +00002098- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2099 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2100 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2101 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00002103- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002104 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002105 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00002107- Issue #5083: New 'gui' resource for regrtest.
