271Core and Builtins
272-----------------
273
Martin v. Löwis8ed91b22009-05-29 16:22:26 +0000274- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
275 of the command line.
276
Martin v. Löwisc15bdef2009-05-29 14:47:46 +0000277- Issue #6012: Add cleanup support to O& argument parsing.
278
Eric Smith41669ca2009-05-23 14:23:22 +0000279- Issue #6089: Fixed str.format with certain invalid field specifiers
280 that would raise SystemError.
281
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000282- Issue #5982: staticmethod and classmethod now expose the wrapped
283 function with __func__.
284
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000285- Added support for multiple context managers in the same with-statement.
286 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +0000287
Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000288- Issue #5829: complex("1e500") no longer raises OverflowError. This
289 makes it consistent with float("1e500") and interpretation of real
290 and imaginary literals.
291
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000292- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
293
R. David Murraydd226ea2009-05-13 12:27:21 +0000294- Issue #5994: the marshal module now has docstrings.
295
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000296- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
297 (1) inf and nan strings with trailing whitespace were incorrectly
298 rejected; (2) parsing of strings representing infinities and nans
299 was locale aware; and (3) the interpretation of fromhex('-nan')
300 didn't match that of float('-nan').

303-------
304
Martin v. Löwisb6a748b2009-05-29 15:23:17 +0000305- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
306
R. David Murrayfb123912009-05-28 18:19:00 +0000307- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
308
R. David Murray1f1b9d32009-05-27 20:56:59 +0000309- Issue #6121: pydoc now ignores leading and trailing spaces in the
310 argument to the 'help' function.
311
Georg Brandlfaf41492009-05-26 18:31:11 +0000312- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
313 arguments for strings with a space in them.
314
Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000315- collections.namedtuple() was not working with the following field
316 names: cls, self, tuple, itemgetter, and property.
317
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000318- In unittest, using a skipping decorator on a class is now equivalent to
319 skipping every test on the class. The ClassTestSuite class has been removed.
320
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000321- Issue #6050: Don't fail extracting a directory from a zipfile if
322 the directory already exists.
323
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000324- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
325 than an int, which makes some operations possible under 64-bit Linux (e.g.
326 DN_MULTISHOT with F_NOTIFY).
327
Antoine Pitrou716c4442009-05-23 19:04:03 +0000328- Issue #5761: Add the name of the underlying file to the repr() of various

330
R. David Murraycaa27b72009-05-23 18:49:56 +0000331- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
332 by Musashi Tamura, tests by Marcin Bachry.
333
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000334- Issue #1983: Fix functions taking or returning a process identifier to use
335 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
336 a process identifier type wider than the standard C integer type.
337
R. David Murray87e20742009-05-23 01:30:26 +0000338- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
339 Patch by Farhan Ahmad, test by Marcin Bachry.
340
Antoine Pitrou6e610062009-05-15 17:04:50 +0000341- Issue #2116: Weak references and weak dictionaries now support copy()ing and
342 deepcopy()ing.
343
Antoine Pitrouc1d09362009-05-15 12:15:51 +0000344- Issue #1655: Make imaplib IPv6-capable. Patch by Derek Morr.

Antoine Pitrou2ca24f02009-05-14 21:30:46 +0000348- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
349
Antoine Pitroue4501852009-05-14 18:55:55 +0000350- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
351 library. This means, for example, that opening an UTF-16 text file in
352 append mode doesn't add a BOM at the end of the file if the file isn't
353 empty.
354
R. David Murray74b89242009-05-13 17:33:03 +0000355- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
356 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
357 corrects a pydoc regression.
358
R. David Murray99352742009-05-07 18:24:38 +0000359- Issue 5955: aifc's close method did not close the file it wrapped,
360 now it does. This also means getfp method now returns the real fp.
361
Benjamin Peterson932073a2009-05-23 16:14:33 +0000362Installation
363------------
364
365- Issue #6047: fullinstall has been removed because Python 3's executable will
366 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +0000367
Ronald Oussorenbe7149e2009-05-26 21:39:08 +0000368- Lib/smtpd.py is no longer installed as a script.

Antoine Pitrou20327222009-05-24 20:39:11 +0000382Build
383-----
384
385- Issue #3585: Add pkg-config support. It creates a python-2.7.pc file

387 Clinton Roy.
388
Brett Cannon1262e7c2009-05-11 01:47:11 +0000389Tests
390-----
391
392- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
393 tests on darwin even when the OS was installed on a case-sensitive
394 filesystem. Also fixed tests that should not be run when
395 sys.dont_write_bytecode is true.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000398What's New in Python 3.1 beta 1?
399================================
400
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000401*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000402
403Core and Builtins
404-----------------
405
Mark Dickinson865e01a2009-05-07 16:37:01 +0000406- Issue #5914: Add new C API function PyOS_string_to_double, and
407 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
408
Eric Smith741191f2009-05-06 13:08:15 +0000409- Issue #3382: float.__format__, complex.__format__, and %-formatting
410 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
411 affects nan -> NAN and inf -> INF.
412
Mark Hammond5a607a32009-05-06 08:04:54 +0000413- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
414 in all operations, including splitdrive, split, etc. splitunc() now issues
415 a PendingDeprecation warning.
416
Eric Smith63376222009-05-05 14:04:18 +0000417- Issue #5920: For float.__format__, change the behavior with the
418 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
419 to be like 'g' but with at least one decimal point and with a
420 default precision of 12. Previously, the behavior the same but with
421 a default precision of 6. This more closely matches str(), and
422 reduces surprises when adding alignment flags to the empty
423 presentation type. This also affects the new complex.__format__ in
424 the same way.
425
Martin v. Löwis011e8422009-05-05 04:43:17 +0000426- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
427
R. David Murrayb18500d2009-05-04 22:59:07 +0000428- Issue #5890: in subclasses of 'property' the __doc__ attribute was
429 shadowed by classtype's, even if it was None. property now
430 inserts the __doc__ into the subclass instance __dict__.
431
Antoine Pitrou244651a2009-05-04 18:56:13 +0000432- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
433 sequences. Patch by Nick Barnes and Victor Stinner.
434
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000435- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000436
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000437- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
438 received a new method, detach(). detach() disconnects the underlying stream
439 from the buffer or text IO and returns it.
440
Mark Dickinson33841c32009-05-01 15:37:04 +0000441- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
442 floats with absolute value over 1e50. Also remove length
443 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
444 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000445
Eric Smith741191f2009-05-06 13:08:15 +0000446- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000447 format(complex(1, 2./3), '.5') now produces a sensible result.
448
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000449- Issue #5864: Fix empty format code formatting for floats so that it
450 never gives more than the requested number of significant digits.
451
Eric Smith6dc46f52009-04-27 20:39:49 +0000452- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
453 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
454
Eric Smithcc32a112009-04-26 21:35:14 +0000455- Issue #5835: Deprecate PyOS_ascii_formatd.
456
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000457- Issue #4971: Fix titlecase for characters that are their own
458 titlecase, but not their own uppercase.
459
Benjamin Peterson193152c2009-04-25 01:08:45 +0000460- Issue #5283: Setting __class__ in __del__ caused a segfault.
461
Mark Dickinsonad476da2009-04-23 19:14:16 +0000462- Issue #5816: complex(repr(z)) now recovers z exactly, even when
463 z involves nans, infs or negative zeros.
464
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000465- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000466
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000467- Issue #1869 (and many duplicates): make round(x, n) correctly
468 rounded for a float x, by using the decimal <-> binary conversions
469 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
470 consistently agrees with format(x, '.2f').
471
Benjamin Petersonae937c02009-04-18 20:54:08 +0000472- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
473 some builtin types.
474
Eric Smith0923d1d2009-04-16 20:16:10 +0000475- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
476
Eric Smith35e84722009-04-16 20:21:28 +0000477- Issue #5515: str.format() type 'n' combined with commas and leading
478 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000479
480- Implement PEP 378, Format Specifier for Thousands Separator, for
481 floats.
482
Mark Dickinson3370cce2009-04-17 22:40:53 +0000483- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000484 1e11, not 1e12. This avoids printing 13 significant digits in
485 situations where only 12 of them are correct. Example problem
486 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
487 long time.)
488
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000489- Issue #1580: On most platforms, use a 'short' float repr: for a
490 finite float x, repr(x) now outputs a string based on the shortest
491 sequence of decimal digits that rounds to x. Previous behaviour was
492 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000493 Another minor difference is that the new repr switches to
494 exponential notation at 1e16 instead of the previous 1e17; this
495 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000496
497 There's a new sys attribute sys.float_repr_style, which takes
498 the value 'short' to indicate that we're using short float repr,
499 and 'legacy' if the short float repr isn't available for one
500 reason or another.
501
502 The float repr change involves incorporating David Gay's 'perfect
503 rounding' code into the Python core (it's in Python/dtoa.c). As a
504 secondary consequence, all string-to-float and float-to-string
505 conversions (including all float formatting operations) will be
506 correctly rounded on these platforms.
507
508 See issue 1580 discussions for details of platforms for which
509 this change does not apply.
510
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000511- Issue #5759: float() didn't call __float__ on str subclasses.
512
Georg Brandlabc38772009-04-12 15:51:51 +0000513- The string.maketrans() function is deprecated; there is a new static method
514 maketrans() on the bytes and bytearray classes. This removes confusion about
515 the types string.maketrans() is supposed to work with, and mirrors the
516 methods available on the str class.
517
R. David Murraydc6da8a2009-04-09 22:16:43 +0000518- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
519 its clarity and its speed.
520
Matthias Klose091c7b12009-04-07 13:24:27 +0000521- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
522 to avoid compiler warnings.
523
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000524- Issue #3739: The unicode-internal encoder now reports the number of characters
525 consumed like any other encoder (instead of the number of bytes).

540
Vinay Sajipaffbd872009-06-11 10:11:47 +0000541- Issue #5940: distutils.command.build_clib.check_library_list was not doing

756 forever on incomplete input. That caused tarfile.open() to hang when used
757 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
758 partial bzip2 compressed data.

875 flag to work properly. Furthermore, when specifying -u, the text stdout
876 and stderr streams have line-by-line buffering enabled (the default being
877 to buffer arbitrary chunks of data).
878
Raymond Hettinger35631532009-01-09 03:58:09 +0000879- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
880 instead of ints (reducing its size from 4 to 8 times thereby reducing
881 Python's overall memory).
882
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000883- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
884 an existing .py counterpart, override the co_filename attributes of all
885 code objects if the original filename is obsolete (which can happen if the
886 file has been renamed, moved, or if it is accessed through different paths).
887 Patch by Ziga Seilnacht and Jean-Paul Calderone.
888
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000889- Issue #4580: Fix slicing of memoryviews when the item size is greater than
890 one byte. Also fixes the meaning of len() so that it returns the number of
891 items, rather than the size in bytes.
892
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000893- Issue #4075: Use OutputDebugStringW in Py_FatalError.

906
Georg Brandlccc47b62008-12-28 11:44:14 +0000907- Issue #4759: None is now allowed as the first argument of

909

933
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000934- Issue #4445: Replace "sizeof(PyBytesObject)" with
935 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
936 bytes instances. On a typical machine this saves 3 bytes of memory
937 (on average) per allocation of a bytes instance.
938
Christian Heimesa872de52008-12-05 08:26:55 +0000939- Issue #4533: File read operation was dreadfully slow due to a slowly

941 Python 2.x.
942
Antoine Pitrou5504e892008-12-06 21:27:53 +0000943- Issue #4509: Various issues surrounding resize of bytearray objects to
944 which there are buffer exports (e.g. memoryview instances).
945
Georg Brandlf9734072008-12-07 15:30:06 +0000946- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
947 method on file objects with closefd=False. The file descriptor is still
948 kept open but the file object behaves like a closed file. The ``FileIO``
949 object also got a new readonly attribute ``closefd``.

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

Guilherme Polo2a998fa2009-06-21 17:40:07 +00001521- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
1522 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
1523 the same behaviour as test_ttkguionly (and now also test_tk) which is to
1524 skip the tests if DISPLAY is defined but can't be used.

Vinay Sajipad5fa2f2009-04-27 13:55:05 +00001527 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00001528 from test support, which does the conversion.
