329 names: cls, self, tuple, itemgetter, and property.
330
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000331- In unittest, using a skipping decorator on a class is now equivalent to
332 skipping every test on the class. The ClassTestSuite class has been removed.
333
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000334- Issue #6050: Don't fail extracting a directory from a zipfile if

336
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000337- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
338 than an int, which makes some operations possible under 64-bit Linux (e.g.

348 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
349 a process identifier type wider than the standard C integer type.
350
R. David Murray87e20742009-05-23 01:30:26 +0000351- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

362
Antoine Pitroue4501852009-05-14 18:55:55 +0000363- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
364 library. This means, for example, that opening an UTF-16 text file in
365 append mode doesn't add a BOM at the end of the file if the file isn't
366 empty.
367
R. David Murray74b89242009-05-13 17:33:03 +0000368- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
369 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
370 corrects a pydoc regression.
371
R. David Murray99352742009-05-07 18:24:38 +0000372- Issue 5955: aifc's close method did not close the file it wrapped,
373 now it does. This also means getfp method now returns the real fp.

416Core and Builtins
417-----------------
418
Mark Dickinson865e01a2009-05-07 16:37:01 +0000419- Issue #5914: Add new C API function PyOS_string_to_double, and
420 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
421
Eric Smith741191f2009-05-06 13:08:15 +0000422- Issue #3382: float.__format__, complex.__format__, and %-formatting
423 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
424 affects nan -> NAN and inf -> INF.
425
Mark Hammond5a607a32009-05-06 08:04:54 +0000426- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
427 in all operations, including splitdrive, split, etc. splitunc() now issues
428 a PendingDeprecation warning.
429
Eric Smith63376222009-05-05 14:04:18 +0000430- Issue #5920: For float.__format__, change the behavior with the
431 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
432 to be like 'g' but with at least one decimal point and with a
433 default precision of 12. Previously, the behavior the same but with
434 a default precision of 6. This more closely matches str(), and
435 reduces surprises when adding alignment flags to the empty
436 presentation type. This also affects the new complex.__format__ in
437 the same way.
438
Martin v. Löwis011e8422009-05-05 04:43:17 +0000439- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
440
R. David Murrayb18500d2009-05-04 22:59:07 +0000441- Issue #5890: in subclasses of 'property' the __doc__ attribute was
442 shadowed by classtype's, even if it was None. property now
443 inserts the __doc__ into the subclass instance __dict__.
444
Antoine Pitrou244651a2009-05-04 18:56:13 +0000445- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
446 sequences. Patch by Nick Barnes and Victor Stinner.
447
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000448- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000449
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000450- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
451 received a new method, detach(). detach() disconnects the underlying stream
452 from the buffer or text IO and returns it.
453
Mark Dickinson33841c32009-05-01 15:37:04 +0000454- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
455 floats with absolute value over 1e50. Also remove length
456 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
457 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000458
Eric Smith741191f2009-05-06 13:08:15 +0000459- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000460 format(complex(1, 2./3), '.5') now produces a sensible result.
461
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000462- Issue #5864: Fix empty format code formatting for floats so that it
463 never gives more than the requested number of significant digits.
464
Eric Smith6dc46f52009-04-27 20:39:49 +0000465- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
466 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
467
Eric Smithcc32a112009-04-26 21:35:14 +0000468- Issue #5835: Deprecate PyOS_ascii_formatd.
469
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000470- Issue #4971: Fix titlecase for characters that are their own
471 titlecase, but not their own uppercase.
472
Benjamin Peterson193152c2009-04-25 01:08:45 +0000473- Issue #5283: Setting __class__ in __del__ caused a segfault.
474
Mark Dickinsonad476da2009-04-23 19:14:16 +0000475- Issue #5816: complex(repr(z)) now recovers z exactly, even when
476 z involves nans, infs or negative zeros.
477
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000478- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000479
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000480- Issue #1869 (and many duplicates): make round(x, n) correctly
481 rounded for a float x, by using the decimal <-> binary conversions
482 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
483 consistently agrees with format(x, '.2f').
484
Benjamin Petersonae937c02009-04-18 20:54:08 +0000485- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
486 some builtin types.
487
Eric Smith0923d1d2009-04-16 20:16:10 +0000488- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
489
Eric Smith35e84722009-04-16 20:21:28 +0000490- Issue #5515: str.format() type 'n' combined with commas and leading
491 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000492
493- Implement PEP 378, Format Specifier for Thousands Separator, for
494 floats.
495
Mark Dickinson3370cce2009-04-17 22:40:53 +0000496- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000497 1e11, not 1e12. This avoids printing 13 significant digits in
498 situations where only 12 of them are correct. Example problem
499 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
500 long time.)
501
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000502- Issue #1580: On most platforms, use a 'short' float repr: for a
503 finite float x, repr(x) now outputs a string based on the shortest
504 sequence of decimal digits that rounds to x. Previous behaviour was
505 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000506 Another minor difference is that the new repr switches to
507 exponential notation at 1e16 instead of the previous 1e17; this
508 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000509
510 There's a new sys attribute sys.float_repr_style, which takes
511 the value 'short' to indicate that we're using short float repr,
512 and 'legacy' if the short float repr isn't available for one
513 reason or another.
514
515 The float repr change involves incorporating David Gay's 'perfect
516 rounding' code into the Python core (it's in Python/dtoa.c). As a
517 secondary consequence, all string-to-float and float-to-string
518 conversions (including all float formatting operations) will be
519 correctly rounded on these platforms.
520
521 See issue 1580 discussions for details of platforms for which
522 this change does not apply.
523
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000524- Issue #5759: float() didn't call __float__ on str subclasses.
525
Georg Brandlabc38772009-04-12 15:51:51 +0000526- The string.maketrans() function is deprecated; there is a new static method
527 maketrans() on the bytes and bytearray classes. This removes confusion about
528 the types string.maketrans() is supposed to work with, and mirrors the
529 methods available on the str class.
530
R. David Murraydc6da8a2009-04-09 22:16:43 +0000531- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
532 its clarity and its speed.
533
Matthias Klose091c7b12009-04-07 13:24:27 +0000534- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
535 to avoid compiler warnings.
536
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000537- Issue #3739: The unicode-internal encoder now reports the number of characters
538 consumed like any other encoder (instead of the number of bytes).

694
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000695- Issue #4688: Add a heuristic so that tuples and dicts containing only
696 untrackable objects are not tracked by the garbage collector. This can
697 reduce the size of collections and therefore the garbage collection overhead
698 on long-running programs, depending on their particular use of datatypes.

769 forever on incomplete input. That caused tarfile.open() to hang when used
770 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
771 partial bzip2 compressed data.
772
Mark Dickinson79f52032009-03-17 23:12:51 +0000773- Issue #2110: Add support for thousands separator and 'n' type

888 flag to work properly. Furthermore, when specifying -u, the text stdout
889 and stderr streams have line-by-line buffering enabled (the default being
890 to buffer arbitrary chunks of data).
891
Raymond Hettinger35631532009-01-09 03:58:09 +0000892- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
893 instead of ints (reducing its size from 4 to 8 times thereby reducing
894 Python's overall memory).
895
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000896- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
897 an existing .py counterpart, override the co_filename attributes of all

903 one byte. Also fixes the meaning of len() so that it returns the number of
904 items, rather than the size in bytes.
905

918 where the tp_hash and tp_dict slots are both NULL.
919
Georg Brandlccc47b62008-12-28 11:44:14 +0000920- Issue #4759: None is now allowed as the first argument of
921 bytearray.translate(). It was always allowed for bytes.translate().
922
Skip Montanaro80072cb2008-12-23 03:51:14 +0000923- Added test case to ensure attempts to read from a file opened for writing

1281 do an explicit seek to the end of file (so that e.g. tell() returns the

1566 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
1567 the same behaviour as test_ttkguionly (and now also test_tk) which is to
1568 skip the tests if DISPLAY is defined but can't be used.
1569
R. David Murraya21e4ca2009-03-31 23:16:50 +00001570- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00001571 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00001572 from test support, which does the conversion.
