321Core and Builtins
322-----------------
323
Martin v. Löwis8ed91b22009-05-29 16:22:26 +0000324- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
325 of the command line.
326
Martin v. Löwisc15bdef2009-05-29 14:47:46 +0000327- Issue #6012: Add cleanup support to O& argument parsing.
328
Eric Smith41669ca2009-05-23 14:23:22 +0000329- Issue #6089: Fixed str.format with certain invalid field specifiers
330 that would raise SystemError.
331
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000332- Issue #5982: staticmethod and classmethod now expose the wrapped
333 function with __func__.
334
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000335- Added support for multiple context managers in the same with-statement.
336 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +0000337
Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000338- Issue #5829: complex("1e500") no longer raises OverflowError. This
339 makes it consistent with float("1e500") and interpretation of real
340 and imaginary literals.
341
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000342- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
343
R. David Murraydd226ea2009-05-13 12:27:21 +0000344- Issue #5994: the marshal module now has docstrings.
345
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000346- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
347 (1) inf and nan strings with trailing whitespace were incorrectly
348 rejected; (2) parsing of strings representing infinities and nans
349 was locale aware; and (3) the interpretation of fromhex('-nan')
350 didn't match that of float('-nan').

353-------
354
Martin v. Löwisb6a748b2009-05-29 15:23:17 +0000355- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
356
R. David Murrayfb123912009-05-28 18:19:00 +0000357- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
358
R. David Murray1f1b9d32009-05-27 20:56:59 +0000359- Issue #6121: pydoc now ignores leading and trailing spaces in the
360 argument to the 'help' function.
361
Georg Brandlfaf41492009-05-26 18:31:11 +0000362- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
363 arguments for strings with a space in them.
364
Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000365- collections.namedtuple() was not working with the following field
366 names: cls, self, tuple, itemgetter, and property.
367
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000368- In unittest, using a skipping decorator on a class is now equivalent to
369 skipping every test on the class. The ClassTestSuite class has been removed.
370
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000371- Issue #6050: Don't fail extracting a directory from a zipfile if
372 the directory already exists.
373
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000374- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
375 than an int, which makes some operations possible under 64-bit Linux (e.g.
376 DN_MULTISHOT with F_NOTIFY).
377
Antoine Pitrou716c4442009-05-23 19:04:03 +0000378- Issue #5761: Add the name of the underlying file to the repr() of various
379 IO objects.
380
R. David Murraycaa27b72009-05-23 18:49:56 +0000381- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
382 by Musashi Tamura, tests by Marcin Bachry.
383
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000384- Issue #1983: Fix functions taking or returning a process identifier to use
385 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
386 a process identifier type wider than the standard C integer type.
387
R. David Murray87e20742009-05-23 01:30:26 +0000388- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
389 Patch by Farhan Ahmad, test by Marcin Bachry.
390
Antoine Pitrou6e610062009-05-15 17:04:50 +0000391- Issue #2116: Weak references and weak dictionaries now support copy()ing and
392 deepcopy()ing.
393
Antoine Pitrouc1d09362009-05-15 12:15:51 +0000394- Issue #1655: Make imaplib IPv6-capable. Patch by Derek Morr.
395
Antoine Pitrou37d1c182009-05-14 21:54:00 +0000396- Issue #5918: Fix a crash in the parser module.
397
Antoine Pitrou2ca24f02009-05-14 21:30:46 +0000398- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
399
Antoine Pitroue4501852009-05-14 18:55:55 +0000400- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
401 library. This means, for example, that opening an UTF-16 text file in
402 append mode doesn't add a BOM at the end of the file if the file isn't
403 empty.
404
R. David Murray74b89242009-05-13 17:33:03 +0000405- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
406 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
407 corrects a pydoc regression.
408
R. David Murray99352742009-05-07 18:24:38 +0000409- Issue 5955: aifc's close method did not close the file it wrapped,
410 now it does. This also means getfp method now returns the real fp.
411
Benjamin Peterson932073a2009-05-23 16:14:33 +0000412Installation
413------------
414
415- Issue #6047: fullinstall has been removed because Python 3's executable will
416 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +0000417
Ronald Oussorenbe7149e2009-05-26 21:39:08 +0000418- Lib/smtpd.py is no longer installed as a script.

433-----
434
435- Issue #3585: Add pkg-config support. It creates a python-2.7.pc file
436 and a python3.pc symlink in the $(LIBDIR)/pkgconfig directory. Patch by
437 Clinton Roy.
438
Brett Cannon1262e7c2009-05-11 01:47:11 +0000439Tests
440-----
441
442- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
443 tests on darwin even when the OS was installed on a case-sensitive
444 filesystem. Also fixed tests that should not be run when
445 sys.dont_write_bytecode is true.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000448What's New in Python 3.1 beta 1?
449================================
450
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000451*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000452
453Core and Builtins
454-----------------
455
Mark Dickinson865e01a2009-05-07 16:37:01 +0000456- Issue #5914: Add new C API function PyOS_string_to_double, and
457 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
458
Eric Smith741191f2009-05-06 13:08:15 +0000459- Issue #3382: float.__format__, complex.__format__, and %-formatting
460 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
461 affects nan -> NAN and inf -> INF.
462
Mark Hammond5a607a32009-05-06 08:04:54 +0000463- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
464 in all operations, including splitdrive, split, etc. splitunc() now issues
465 a PendingDeprecation warning.
466
Eric Smith63376222009-05-05 14:04:18 +0000467- Issue #5920: For float.__format__, change the behavior with the
468 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
469 to be like 'g' but with at least one decimal point and with a
470 default precision of 12. Previously, the behavior the same but with
471 a default precision of 6. This more closely matches str(), and
472 reduces surprises when adding alignment flags to the empty
473 presentation type. This also affects the new complex.__format__ in
474 the same way.
475
Martin v. Löwis011e8422009-05-05 04:43:17 +0000476- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
477
R. David Murrayb18500d2009-05-04 22:59:07 +0000478- Issue #5890: in subclasses of 'property' the __doc__ attribute was
479 shadowed by classtype's, even if it was None. property now
480 inserts the __doc__ into the subclass instance __dict__.
481
Antoine Pitrou244651a2009-05-04 18:56:13 +0000482- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
483 sequences. Patch by Nick Barnes and Victor Stinner.
484
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000485- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000486
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000487- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
488 received a new method, detach(). detach() disconnects the underlying stream
489 from the buffer or text IO and returns it.
490
Mark Dickinson33841c32009-05-01 15:37:04 +0000491- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
492 floats with absolute value over 1e50. Also remove length
493 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
494 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000495
Eric Smith741191f2009-05-06 13:08:15 +0000496- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000497 format(complex(1, 2./3), '.5') now produces a sensible result.
498
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000499- Issue #5864: Fix empty format code formatting for floats so that it
500 never gives more than the requested number of significant digits.
501
Eric Smith6dc46f52009-04-27 20:39:49 +0000502- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
503 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
504
Eric Smithcc32a112009-04-26 21:35:14 +0000505- Issue #5835: Deprecate PyOS_ascii_formatd.
506
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000507- Issue #4971: Fix titlecase for characters that are their own
508 titlecase, but not their own uppercase.
509
Benjamin Peterson193152c2009-04-25 01:08:45 +0000510- Issue #5283: Setting __class__ in __del__ caused a segfault.
511
Mark Dickinsonad476da2009-04-23 19:14:16 +0000512- Issue #5816: complex(repr(z)) now recovers z exactly, even when
513 z involves nans, infs or negative zeros.
514
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000515- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000516
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000517- Issue #1869 (and many duplicates): make round(x, n) correctly
518 rounded for a float x, by using the decimal <-> binary conversions
519 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
520 consistently agrees with format(x, '.2f').
521
Benjamin Petersonae937c02009-04-18 20:54:08 +0000522- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
523 some builtin types.
524
Eric Smith0923d1d2009-04-16 20:16:10 +0000525- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
526
Eric Smith35e84722009-04-16 20:21:28 +0000527- Issue #5515: str.format() type 'n' combined with commas and leading
528 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000529
530- Implement PEP 378, Format Specifier for Thousands Separator, for
531 floats.
532
Mark Dickinson3370cce2009-04-17 22:40:53 +0000533- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000534 1e11, not 1e12. This avoids printing 13 significant digits in
535 situations where only 12 of them are correct. Example problem
536 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
537 long time.)
538
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000539- Issue #1580: On most platforms, use a 'short' float repr: for a
540 finite float x, repr(x) now outputs a string based on the shortest
541 sequence of decimal digits that rounds to x. Previous behaviour was
542 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000543 Another minor difference is that the new repr switches to
544 exponential notation at 1e16 instead of the previous 1e17; this
545 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000546
547 There's a new sys attribute sys.float_repr_style, which takes
548 the value 'short' to indicate that we're using short float repr,
549 and 'legacy' if the short float repr isn't available for one
550 reason or another.
551
552 The float repr change involves incorporating David Gay's 'perfect
553 rounding' code into the Python core (it's in Python/dtoa.c). As a
554 secondary consequence, all string-to-float and float-to-string
555 conversions (including all float formatting operations) will be
556 correctly rounded on these platforms.
557
558 See issue 1580 discussions for details of platforms for which
559 this change does not apply.
560
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000561- Issue #5759: float() didn't call __float__ on str subclasses.
562
Georg Brandlabc38772009-04-12 15:51:51 +0000563- The string.maketrans() function is deprecated; there is a new static method
564 maketrans() on the bytes and bytearray classes. This removes confusion about
565 the types string.maketrans() is supposed to work with, and mirrors the
566 methods available on the str class.
567
R. David Murraydc6da8a2009-04-09 22:16:43 +0000568- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
569 its clarity and its speed.
570
Matthias Klose091c7b12009-04-07 13:24:27 +0000571- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
572 to avoid compiler warnings.
573
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000574- Issue #3739: The unicode-internal encoder now reports the number of characters
575 consumed like any other encoder (instead of the number of bytes).

590
Vinay Sajipaffbd872009-06-11 10:11:47 +0000591- Issue #5940: distutils.command.build_clib.check_library_list was not doing

Benjamin Peterson8f76b492009-04-03 22:22:42 +0000710- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
711
Benjamin Peterson7fe98532009-04-02 00:33:55 +0000712- Issue #5499: The 'c' code for argument parsing functions now only accepts a
713 byte, and the 'C' code only accepts a unicode character.
714

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

806 forever on incomplete input. That caused tarfile.open() to hang when used
807 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
808 partial bzip2 compressed data.
809
Mark Dickinson79f52032009-03-17 23:12:51 +0000810- Issue #2110: Add support for thousands separator and 'n' type

Antoine Pitroud35cbf62009-01-06 19:02:24 +0000933- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
934 an existing .py counterpart, override the co_filename attributes of all
935 code objects if the original filename is obsolete (which can happen if the
936 file has been renamed, moved, or if it is accessed through different paths).
937 Patch by Ziga Seilnacht and Jean-Paul Calderone.

983
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000984- Issue #4445: Replace "sizeof(PyBytesObject)" with
985 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for

995
Georg Brandlf9734072008-12-07 15:30:06 +0000996- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
997 method on file objects with closefd=False. The file descriptor is still
998 kept open but the file object behaves like a closed file. The ``FileIO``
999 object also got a new readonly attribute ``closefd``.

1009 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1010 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1011 of using the replace error handler in PyUnicode_DecodeUTF8().

1315
Antoine Pitrou08838b62009-01-21 00:55:13 +00001316- Issue #5008: When a file is opened in append mode with the new IO library,
1317 do an explicit seek to the end of file (so that e.g. tell() returns the
1318 file size rather than 0). This is consistent with the behaviour of the
