Antoine Pitroud9dfaa92009-06-04 20:32:06 +000024- Issue #6137: The pickle module now translates module names when loading
25 or dumping pickles with a 2.x-compatible protocol, in order to make data
26 sharing and migration easier. This behaviour can be disabled using the
27 new `fix_imports` optional argument.
28
Raymond Hettinger40925d22009-06-04 18:32:39 +000029- Removed the ipaddr module.

Georg Brandlb54d8012009-06-04 09:11:51 +000031- Issue #3613: base64.{encode,decode}string are now called
32 base64.{encode,decode}bytes which reflects what type they accept and return.
33 The old names are still there as deprecated aliases.
34
Georg Brandl317185a2009-06-04 09:00:56 +000035- Issue #5767: Remove sgmlop support from xmlrpc.client.

61-----------------
62
Martin v. Löwis8ed91b22009-05-29 16:22:26 +000063- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
64 of the command line.
65
Martin v. Löwisc15bdef2009-05-29 14:47:46 +000066- Issue #6012: Add cleanup support to O& argument parsing.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +000077- Issue #5829: complex("1e500") no longer raises OverflowError. This
78 makes it consistent with float("1e500") and interpretation of real
79 and imaginary literals.
80
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +000081- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

84
Mark Dickinsond1ec8b22009-05-11 15:45:15 +000085- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
86 (1) inf and nan strings with trailing whitespace were incorrectly
87 rejected; (2) parsing of strings representing infinities and nans
88 was locale aware; and (3) the interpretation of fromhex('-nan')
89 didn't match that of float('-nan').

105 names: cls, self, tuple, itemgetter, and property.
106
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000107- In unittest, using a skipping decorator on a class is now equivalent to
108 skipping every test on the class. The ClassTestSuite class has been removed.
109
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000110- Issue #6050: Don't fail extracting a directory from a zipfile if
111 the directory already exists.
112
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000113- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
114 than an int, which makes some operations possible under 64-bit Linux (e.g.
115 DN_MULTISHOT with F_NOTIFY).
116
Antoine Pitrou716c4442009-05-23 19:04:03 +0000117- Issue #5761: Add the name of the underlying file to the repr() of various

119
R. David Murraycaa27b72009-05-23 18:49:56 +0000120- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
121 by Musashi Tamura, tests by Marcin Bachry.
122
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000123- Issue #1983: Fix functions taking or returning a process identifier to use
124 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
125 a process identifier type wider than the standard C integer type.
126
R. David Murray87e20742009-05-23 01:30:26 +0000127- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
128 Patch by Farhan Ahmad, test by Marcin Bachry.
129
Antoine Pitrou6e610062009-05-15 17:04:50 +0000130- Issue #2116: Weak references and weak dictionaries now support copy()ing and
131 deepcopy()ing.

Antoine Pitrou2ca24f02009-05-14 21:30:46 +0000137- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
138
Antoine Pitroue4501852009-05-14 18:55:55 +0000139- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
140 library. This means, for example, that opening an UTF-16 text file in
141 append mode doesn't add a BOM at the end of the file if the file isn't
142 empty.
143
R. David Murray74b89242009-05-13 17:33:03 +0000144- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
145 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
146 corrects a pydoc regression.
147
R. David Murray99352742009-05-07 18:24:38 +0000148- Issue 5955: aifc's close method did not close the file it wrapped,
149 now it does. This also means getfp method now returns the real fp.
150
Benjamin Peterson932073a2009-05-23 16:14:33 +0000151Installation
152------------
153
154- Issue #6047: fullinstall has been removed because Python 3's executable will

Brett Cannon1262e7c2009-05-11 01:47:11 +0000178Tests
179-----
180
181- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
182 tests on darwin even when the OS was installed on a case-sensitive

192Core and Builtins
193-----------------
194
Mark Dickinson865e01a2009-05-07 16:37:01 +0000195- Issue #5914: Add new C API function PyOS_string_to_double, and
196 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
197
Eric Smith741191f2009-05-06 13:08:15 +0000198- Issue #3382: float.__format__, complex.__format__, and %-formatting
199 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
200 affects nan -> NAN and inf -> INF.
201
Mark Hammond5a607a32009-05-06 08:04:54 +0000202- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
203 in all operations, including splitdrive, split, etc. splitunc() now issues
204 a PendingDeprecation warning.
205
Eric Smith63376222009-05-05 14:04:18 +0000206- Issue #5920: For float.__format__, change the behavior with the
207 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
208 to be like 'g' but with at least one decimal point and with a
209 default precision of 12. Previously, the behavior the same but with
210 a default precision of 6. This more closely matches str(), and
211 reduces surprises when adding alignment flags to the empty
212 presentation type. This also affects the new complex.__format__ in
213 the same way.
214
Martin v. Löwis011e8422009-05-05 04:43:17 +0000215- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
216
R. David Murrayb18500d2009-05-04 22:59:07 +0000217- Issue #5890: in subclasses of 'property' the __doc__ attribute was
218 shadowed by classtype's, even if it was None. property now
219 inserts the __doc__ into the subclass instance __dict__.
220
Antoine Pitrou244651a2009-05-04 18:56:13 +0000221- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
222 sequences. Patch by Nick Barnes and Victor Stinner.
223
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000224- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000225
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000226- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
227 received a new method, detach(). detach() disconnects the underlying stream
228 from the buffer or text IO and returns it.
229
Mark Dickinson33841c32009-05-01 15:37:04 +0000230- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
231 floats with absolute value over 1e50. Also remove length
232 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
233 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000234
Eric Smith741191f2009-05-06 13:08:15 +0000235- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000236 format(complex(1, 2./3), '.5') now produces a sensible result.
237
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000238- Issue #5864: Fix empty format code formatting for floats so that it
239 never gives more than the requested number of significant digits.
240
Eric Smith6dc46f52009-04-27 20:39:49 +0000241- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
242 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
243
Eric Smithcc32a112009-04-26 21:35:14 +0000244- Issue #5835: Deprecate PyOS_ascii_formatd.
245
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000246- Issue #4971: Fix titlecase for characters that are their own
247 titlecase, but not their own uppercase.
248
Benjamin Peterson193152c2009-04-25 01:08:45 +0000249- Issue #5283: Setting __class__ in __del__ caused a segfault.
250
Mark Dickinsonad476da2009-04-23 19:14:16 +0000251- Issue #5816: complex(repr(z)) now recovers z exactly, even when
252 z involves nans, infs or negative zeros.
253
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000254- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000255
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000256- Issue #1869 (and many duplicates): make round(x, n) correctly
257 rounded for a float x, by using the decimal <-> binary conversions
258 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
259 consistently agrees with format(x, '.2f').
260
Benjamin Petersonae937c02009-04-18 20:54:08 +0000261- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
262 some builtin types.
263
Eric Smith0923d1d2009-04-16 20:16:10 +0000264- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
265
Eric Smith35e84722009-04-16 20:21:28 +0000266- Issue #5515: str.format() type 'n' combined with commas and leading
267 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000268
269- Implement PEP 378, Format Specifier for Thousands Separator, for
270 floats.
271
Mark Dickinson3370cce2009-04-17 22:40:53 +0000272- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000273 1e11, not 1e12. This avoids printing 13 significant digits in
274 situations where only 12 of them are correct. Example problem
275 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
276 long time.)
277
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000278- Issue #1580: On most platforms, use a 'short' float repr: for a
279 finite float x, repr(x) now outputs a string based on the shortest
280 sequence of decimal digits that rounds to x. Previous behaviour was
281 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000282 Another minor difference is that the new repr switches to
283 exponential notation at 1e16 instead of the previous 1e17; this
284 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000285
286 There's a new sys attribute sys.float_repr_style, which takes
287 the value 'short' to indicate that we're using short float repr,
288 and 'legacy' if the short float repr isn't available for one
289 reason or another.
290
291 The float repr change involves incorporating David Gay's 'perfect
292 rounding' code into the Python core (it's in Python/dtoa.c). As a
293 secondary consequence, all string-to-float and float-to-string
294 conversions (including all float formatting operations) will be
295 correctly rounded on these platforms.
296
297 See issue 1580 discussions for details of platforms for which
298 this change does not apply.
299
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000300- Issue #5759: float() didn't call __float__ on str subclasses.
301
Georg Brandlabc38772009-04-12 15:51:51 +0000302- The string.maketrans() function is deprecated; there is a new static method
303 maketrans() on the bytes and bytearray classes. This removes confusion about
304 the types string.maketrans() is supposed to work with, and mirrors the
305 methods available on the str class.
306
R. David Murraydc6da8a2009-04-09 22:16:43 +0000307- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
308 its clarity and its speed.
309
Matthias Klose091c7b12009-04-07 13:24:27 +0000310- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
311 to avoid compiler warnings.
312
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000313- Issue #3739: The unicode-internal encoder now reports the number of characters
314 consumed like any other encoder (instead of the number of bytes).

630
Mark Dickinson8055afd2009-01-17 10:04:45 +0000631- Issue #4910: Rename nb_long slot to nb_reserved, and change its
632 type to (void *).
633
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000634- Issue #4935: The overflow checking code in the expandtabs() method common
635 to str, bytes and bytearray could be optimized away by the compiler, letting
636 the interpreter segfault instead of raising an error.
637
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000638- Issue #3720: Fix a crash when an iterator modifies its class and removes its
639 __next__ method.
640
Mark Dickinsone5e298f2009-01-12 20:49:19 +0000641- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
642 function no longer attempt to call the __long__ slot to convert an object
643 to an integer. Only the __int__ and __trunc__ slots are examined.
644

648
Antoine Pitrouab868312009-01-10 15:40:25 +0000649- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
650 common cases are optimized thanks to a dedicated fast path and a moderate
651 amount of loop unrolling.
652
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000653- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
654 collecting the oldest generation) so that allocating lots of objects without
655 destroying them does not show quadratic performance. Based on a proposal by
656 Martin von Löwis at
657 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
658
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000659- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000660 having been closed (for instance, a read() call could return some
661 previously buffered data). Patch by Dmitry Vasiliev.
662
Antoine Pitrou05608432009-01-09 18:53:14 +0000663- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
664 flag to work properly. Furthermore, when specifying -u, the text stdout
665 and stderr streams have line-by-line buffering enabled (the default being
666 to buffer arbitrary chunks of data).
667
Raymond Hettinger35631532009-01-09 03:58:09 +0000668- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
669 instead of ints (reducing its size from 4 to 8 times thereby reducing
670 Python's overall memory).
671
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000672- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
673 an existing .py counterpart, override the co_filename attributes of all
674 code objects if the original filename is obsolete (which can happen if the
675 file has been renamed, moved, or if it is accessed through different paths).
676 Patch by Ziga Seilnacht and Jean-Paul Calderone.
677
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000678- Issue #4580: Fix slicing of memoryviews when the item size is greater than
679 one byte. Also fixes the meaning of len() so that it returns the number of
680 items, rather than the size in bytes.
681
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000682- Issue #4075: Use OutputDebugStringW in Py_FatalError.
683
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000684- Issue #4747: When the terminal does not use utf-8, executing a script with
685 non-ascii characters in its name could fail with a "SyntaxError: None" error.
686
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000687- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

691 did not get collected.
692
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000693- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
694 where the tp_hash and tp_dict slots are both NULL.
695
Georg Brandlccc47b62008-12-28 11:44:14 +0000696- Issue #4759: None is now allowed as the first argument of
697 bytearray.translate(). It was always allowed for bytes.translate().
698
Skip Montanaro80072cb2008-12-23 03:51:14 +0000699- Added test case to ensure attempts to read from a file opened for writing
700 fail.

706
Antoine Pitrou621601a2008-12-17 23:18:19 +0000707- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
708 print elapsed times, not only when some objects are uncollectable /
709 unreachable. Original patch by Neil Schemenauer.
710
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000711- Issue #3439: Add a bit_length method to int.
712
Mark Dickinsonda2706b2008-12-11 18:03:03 +0000713- Issue #2173: When getting device encoding, check that return value of
714 nl_langinfo is not the empty string. This was causing silent build
715 failures on OS X.
716
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000717- Issue #4597: Fixed several opcodes that weren't always propagating
718 exceptions.
719
720- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000721 context manager returns a value that cannot be converted to a bool.
722
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000723- Issue #4445: Replace "sizeof(PyBytesObject)" with
724 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
725 bytes instances. On a typical machine this saves 3 bytes of memory
726 (on average) per allocation of a bytes instance.
727
Christian Heimesa872de52008-12-05 08:26:55 +0000728- Issue #4533: File read operation was dreadfully slow due to a slowly
729 growing read buffer. Fixed by using the same growth rate algorithm as
730 Python 2.x.
731
Antoine Pitrou5504e892008-12-06 21:27:53 +0000732- Issue #4509: Various issues surrounding resize of bytearray objects to
733 which there are buffer exports (e.g. memoryview instances).
734
Georg Brandlf9734072008-12-07 15:30:06 +0000735- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
736 method on file objects with closefd=False. The file descriptor is still
737 kept open but the file object behaves like a closed file. The ``FileIO``
738 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000739
Antoine Pitroubc420402008-12-07 20:14:49 +0000740- Issue #4569: Interpreter crash when mutating a memoryview with an item size
741 larger than 1.

746
Walter Dörwaldc1651a02009-05-03 22:55:55 +0000747- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
748 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
749 step. This avoids problems with counting UTF-8 bytes that ignores the effect
750 of using the replace error handler in PyUnicode_DecodeUTF8().
