Antoine Pitroud9dfaa92009-06-04 20:32:06 +0000323- Issue #6137: The pickle module now translates module names when loading
324 or dumping pickles with a 2.x-compatible protocol, in order to make data
325 sharing and migration easier. This behaviour can be disabled using the
326 new `fix_imports` optional argument.

372Core and Builtins
373-----------------
374
Martin v. Löwis8ed91b22009-05-29 16:22:26 +0000375- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
376 of the command line.
377
Martin v. Löwisc15bdef2009-05-29 14:47:46 +0000378- Issue #6012: Add cleanup support to O& argument parsing.

381 that would raise SystemError.
382
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000383- Issue #5982: staticmethod and classmethod now expose the wrapped
384 function with __func__.
385
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000386- Added support for multiple context managers in the same with-statement.
387 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +0000388
Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000389- Issue #5829: complex("1e500") no longer raises OverflowError. This
390 makes it consistent with float("1e500") and interpretation of real
391 and imaginary literals.
392
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000393- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

396
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000397- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
398 (1) inf and nan strings with trailing whitespace were incorrectly
399 rejected; (2) parsing of strings representing infinities and nans
400 was locale aware; and (3) the interpretation of fromhex('-nan')
401 didn't match that of float('-nan').

405
Martin v. Löwisb6a748b2009-05-29 15:23:17 +0000406- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
407
R. David Murrayfb123912009-05-28 18:19:00 +0000408- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
409
R. David Murray1f1b9d32009-05-27 20:56:59 +0000410- Issue #6121: pydoc now ignores leading and trailing spaces in the
411 argument to the 'help' function.
412
Georg Brandlfaf41492009-05-26 18:31:11 +0000413- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
414 arguments for strings with a space in them.
415
Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000416- collections.namedtuple() was not working with the following field
417 names: cls, self, tuple, itemgetter, and property.
418
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000419- In unittest, using a skipping decorator on a class is now equivalent to
420 skipping every test on the class. The ClassTestSuite class has been removed.
421
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000422- Issue #6050: Don't fail extracting a directory from a zipfile if
423 the directory already exists.
424
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000425- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
426 than an int, which makes some operations possible under 64-bit Linux (e.g.
427 DN_MULTISHOT with F_NOTIFY).
428
Antoine Pitrou716c4442009-05-23 19:04:03 +0000429- Issue #5761: Add the name of the underlying file to the repr() of various
430 IO objects.
431
R. David Murraycaa27b72009-05-23 18:49:56 +0000432- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
433 by Musashi Tamura, tests by Marcin Bachry.
434
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000435- Issue #1983: Fix functions taking or returning a process identifier to use
436 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
437 a process identifier type wider than the standard C integer type.
438
R. David Murray87e20742009-05-23 01:30:26 +0000439- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
440 Patch by Farhan Ahmad, test by Marcin Bachry.
441
Antoine Pitrou6e610062009-05-15 17:04:50 +0000442- Issue #2116: Weak references and weak dictionaries now support copy()ing and
443 deepcopy()ing.
444

450
Antoine Pitroue4501852009-05-14 18:55:55 +0000451- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
452 library. This means, for example, that opening an UTF-16 text file in
453 append mode doesn't add a BOM at the end of the file if the file isn't
454 empty.
455
R. David Murray74b89242009-05-13 17:33:03 +0000456- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
457 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
458 corrects a pydoc regression.
459
R. David Murray99352742009-05-07 18:24:38 +0000460- Issue 5955: aifc's close method did not close the file it wrapped,
461 now it does. This also means getfp method now returns the real fp.
462
Benjamin Peterson932073a2009-05-23 16:14:33 +0000463Installation
464------------

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000499What's New in Python 3.1 beta 1?
500================================
501
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000502*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000503
504Core and Builtins
505-----------------
506
Mark Dickinson865e01a2009-05-07 16:37:01 +0000507- Issue #5914: Add new C API function PyOS_string_to_double, and
508 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
509
Eric Smith741191f2009-05-06 13:08:15 +0000510- Issue #3382: float.__format__, complex.__format__, and %-formatting
511 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
512 affects nan -> NAN and inf -> INF.
513
Mark Hammond5a607a32009-05-06 08:04:54 +0000514- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
515 in all operations, including splitdrive, split, etc. splitunc() now issues
516 a PendingDeprecation warning.
517
Eric Smith63376222009-05-05 14:04:18 +0000518- Issue #5920: For float.__format__, change the behavior with the
519 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
520 to be like 'g' but with at least one decimal point and with a
521 default precision of 12. Previously, the behavior the same but with
522 a default precision of 6. This more closely matches str(), and
523 reduces surprises when adding alignment flags to the empty
524 presentation type. This also affects the new complex.__format__ in
525 the same way.
526
Martin v. Löwis011e8422009-05-05 04:43:17 +0000527- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
528
R. David Murrayb18500d2009-05-04 22:59:07 +0000529- Issue #5890: in subclasses of 'property' the __doc__ attribute was
530 shadowed by classtype's, even if it was None. property now
531 inserts the __doc__ into the subclass instance __dict__.
532
Antoine Pitrou244651a2009-05-04 18:56:13 +0000533- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
534 sequences. Patch by Nick Barnes and Victor Stinner.
535
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000536- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000537
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000538- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
539 received a new method, detach(). detach() disconnects the underlying stream
540 from the buffer or text IO and returns it.
541
Mark Dickinson33841c32009-05-01 15:37:04 +0000542- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
543 floats with absolute value over 1e50. Also remove length
544 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
545 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000546
Eric Smith741191f2009-05-06 13:08:15 +0000547- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000548 format(complex(1, 2./3), '.5') now produces a sensible result.
549
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000550- Issue #5864: Fix empty format code formatting for floats so that it
551 never gives more than the requested number of significant digits.
552
Eric Smith6dc46f52009-04-27 20:39:49 +0000553- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
554 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
555
Eric Smithcc32a112009-04-26 21:35:14 +0000556- Issue #5835: Deprecate PyOS_ascii_formatd.
557
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000558- Issue #4971: Fix titlecase for characters that are their own
559 titlecase, but not their own uppercase.
560
Benjamin Peterson193152c2009-04-25 01:08:45 +0000561- Issue #5283: Setting __class__ in __del__ caused a segfault.
562
Mark Dickinsonad476da2009-04-23 19:14:16 +0000563- Issue #5816: complex(repr(z)) now recovers z exactly, even when
564 z involves nans, infs or negative zeros.
565
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000566- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000567
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000568- Issue #1869 (and many duplicates): make round(x, n) correctly
569 rounded for a float x, by using the decimal <-> binary conversions
570 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
571 consistently agrees with format(x, '.2f').
572
Benjamin Petersonae937c02009-04-18 20:54:08 +0000573- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
574 some builtin types.
575
Eric Smith0923d1d2009-04-16 20:16:10 +0000576- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
577
Eric Smith35e84722009-04-16 20:21:28 +0000578- Issue #5515: str.format() type 'n' combined with commas and leading
579 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000580
581- Implement PEP 378, Format Specifier for Thousands Separator, for
582 floats.
583
Mark Dickinson3370cce2009-04-17 22:40:53 +0000584- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000585 1e11, not 1e12. This avoids printing 13 significant digits in
586 situations where only 12 of them are correct. Example problem
587 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
588 long time.)
589
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000590- Issue #1580: On most platforms, use a 'short' float repr: for a
591 finite float x, repr(x) now outputs a string based on the shortest
592 sequence of decimal digits that rounds to x. Previous behaviour was
593 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000594 Another minor difference is that the new repr switches to
595 exponential notation at 1e16 instead of the previous 1e17; this
596 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000597
598 There's a new sys attribute sys.float_repr_style, which takes
599 the value 'short' to indicate that we're using short float repr,
600 and 'legacy' if the short float repr isn't available for one
601 reason or another.
602
603 The float repr change involves incorporating David Gay's 'perfect
604 rounding' code into the Python core (it's in Python/dtoa.c). As a
605 secondary consequence, all string-to-float and float-to-string
606 conversions (including all float formatting operations) will be
607 correctly rounded on these platforms.
608
609 See issue 1580 discussions for details of platforms for which
610 this change does not apply.
611
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000612- Issue #5759: float() didn't call __float__ on str subclasses.
613
Georg Brandlabc38772009-04-12 15:51:51 +0000614- The string.maketrans() function is deprecated; there is a new static method
615 maketrans() on the bytes and bytearray classes. This removes confusion about
616 the types string.maketrans() is supposed to work with, and mirrors the
617 methods available on the str class.
618
R. David Murraydc6da8a2009-04-09 22:16:43 +0000619- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Antoine Pitroub52ec782009-01-25 16:34:23 +0000928- Issue #4753: By enabling a configure option named '--with-computed-gotos'
929 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
930 evaluation loop is compiled with a new dispatch mechanism which gives
931 speedups of up to 20%, depending on the system, on various benchmarks.
932
Antoine Pitrou81fabdb2009-01-22 10:11:36 +0000933- Issue #4874: Most builtin decoders now reject unicode input.

939
Antoine Pitroue4bc7f62009-01-17 21:06:43 +0000940- Issue #4838: When a module is deallocated, free the memory backing the
941 optional module state data.
942
Mark Dickinson8055afd2009-01-17 10:04:45 +0000943- Issue #4910: Rename nb_long slot to nb_reserved, and change its
944 type to (void *).
945
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000946- Issue #4935: The overflow checking code in the expandtabs() method common
947 to str, bytes and bytearray could be optimized away by the compiler, letting
948 the interpreter segfault instead of raising an error.
949
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000950- Issue #3720: Fix a crash when an iterator modifies its class and removes its
951 __next__ method.
952
Mark Dickinsone5e298f2009-01-12 20:49:19 +0000953- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
954 function no longer attempt to call the __long__ slot to convert an object
955 to an integer. Only the __int__ and __trunc__ slots are examined.

960
Antoine Pitrouab868312009-01-10 15:40:25 +0000961- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
962 common cases are optimized thanks to a dedicated fast path and a moderate
963 amount of loop unrolling.
964
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000965- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
966 collecting the oldest generation) so that allocating lots of objects without
967 destroying them does not show quadratic performance. Based on a proposal by
968 Martin von Löwis at
969 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
970
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000971- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000972 having been closed (for instance, a read() call could return some
973 previously buffered data). Patch by Dmitry Vasiliev.
974
Antoine Pitrou05608432009-01-09 18:53:14 +0000975- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
976 flag to work properly. Furthermore, when specifying -u, the text stdout
977 and stderr streams have line-by-line buffering enabled (the default being
978 to buffer arbitrary chunks of data).
979
Raymond Hettinger35631532009-01-09 03:58:09 +0000980- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
981 instead of ints (reducing its size from 4 to 8 times thereby reducing
982 Python's overall memory).
983
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000984- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
985 an existing .py counterpart, override the co_filename attributes of all
986 code objects if the original filename is obsolete (which can happen if the
987 file has been renamed, moved, or if it is accessed through different paths).
988 Patch by Ziga Seilnacht and Jean-Paul Calderone.
989
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000990- Issue #4580: Fix slicing of memoryviews when the item size is greater than
991 one byte. Also fixes the meaning of len() so that it returns the number of
992 items, rather than the size in bytes.
993
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000994- Issue #4075: Use OutputDebugStringW in Py_FatalError.
995
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000996- Issue #4747: When the terminal does not use utf-8, executing a script with
997 non-ascii characters in its name could fail with a "SyntaxError: None" error.
998
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000999- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

1003 did not get collected.
1004
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001005- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1006 where the tp_hash and tp_dict slots are both NULL.
1007
Georg Brandlccc47b62008-12-28 11:44:14 +00001008- Issue #4759: None is now allowed as the first argument of

1010
Skip Montanaro80072cb2008-12-23 03:51:14 +00001011- Added test case to ensure attempts to read from a file opened for writing
1012 fail.
1013

1018
Antoine Pitrou621601a2008-12-17 23:18:19 +00001019- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

Mark Dickinsonda2706b2008-12-11 18:03:03 +00001025- Issue #2173: When getting device encoding, check that return value of
1026 nl_langinfo is not the empty string. This was causing silent build
1027 failures on OS X.
1028
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001029- Issue #4597: Fixed several opcodes that weren't always propagating
1030 exceptions.
1031
1032- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001033 context manager returns a value that cannot be converted to a bool.
1034
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001035- Issue #4445: Replace "sizeof(PyBytesObject)" with
1036 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1037 bytes instances. On a typical machine this saves 3 bytes of memory
1038 (on average) per allocation of a bytes instance.
1039
Christian Heimesa872de52008-12-05 08:26:55 +00001040- Issue #4533: File read operation was dreadfully slow due to a slowly
1041 growing read buffer. Fixed by using the same growth rate algorithm as
1042 Python 2.x.
1043
Antoine Pitrou5504e892008-12-06 21:27:53 +00001044- Issue #4509: Various issues surrounding resize of bytearray objects to
1045 which there are buffer exports (e.g. memoryview instances).
1046
Georg Brandlf9734072008-12-07 15:30:06 +00001047- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1048 method on file objects with closefd=False. The file descriptor is still
1049 kept open but the file object behaves like a closed file. The ``FileIO``
1050 object also got a new readonly attribute ``closefd``.

1058
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001059- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1060 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1061 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1062 of using the replace error handler in PyUnicode_DecodeUTF8().
