Benjamin Peterson0926ad12009-06-06 18:02:12 +000024- Issue #6217: The C implementation of io.TextIOWrapper didn't include the
25 errors property. Additionally, the errors and encoding properties of StringIO
26 are always None now.
27
Antoine Pitroud9dfaa92009-06-04 20:32:06 +000028- Issue #6137: The pickle module now translates module names when loading
29 or dumping pickles with a 2.x-compatible protocol, in order to make data
30 sharing and migration easier. This behaviour can be disabled using the
31 new `fix_imports` optional argument.
32
Raymond Hettinger40925d22009-06-04 18:32:39 +000033- Removed the ipaddr module.
34
Georg Brandlb54d8012009-06-04 09:11:51 +000035- Issue #3613: base64.{encode,decode}string are now called
36 base64.{encode,decode}bytes which reflects what type they accept and return.
37 The old names are still there as deprecated aliases.
38
Georg Brandl317185a2009-06-04 09:00:56 +000039- Issue #5767: Remove sgmlop support from xmlrpc.client.

75 that would raise SystemError.
76
Raymond Hettinger2bcde142009-05-29 04:52:27 +000077- Issue #5982: staticmethod and classmethod now expose the wrapped
78 function with __func__.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +000083- Issue #5829: complex("1e500") no longer raises OverflowError. This
84 makes it consistent with float("1e500") and interpretation of real
85 and imaginary literals.
86
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +000087- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

90
Mark Dickinsond1ec8b22009-05-11 15:45:15 +000091- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
92 (1) inf and nan strings with trailing whitespace were incorrectly
93 rejected; (2) parsing of strings representing infinities and nans
94 was locale aware; and (3) the interpretation of fromhex('-nan')
95 didn't match that of float('-nan').

105 argument to the 'help' function.
106
Georg Brandlfaf41492009-05-26 18:31:11 +0000107- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
108 arguments for strings with a space in them.
109
Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000110- collections.namedtuple() was not working with the following field
111 names: cls, self, tuple, itemgetter, and property.
112
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000113- In unittest, using a skipping decorator on a class is now equivalent to
114 skipping every test on the class. The ClassTestSuite class has been removed.
115
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000116- Issue #6050: Don't fail extracting a directory from a zipfile if
117 the directory already exists.
118
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000119- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
120 than an int, which makes some operations possible under 64-bit Linux (e.g.
121 DN_MULTISHOT with F_NOTIFY).
122
Antoine Pitrou716c4442009-05-23 19:04:03 +0000123- Issue #5761: Add the name of the underlying file to the repr() of various

R. David Murraycaa27b72009-05-23 18:49:56 +0000126- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
127 by Musashi Tamura, tests by Marcin Bachry.
128
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000129- Issue #1983: Fix functions taking or returning a process identifier to use
130 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
131 a process identifier type wider than the standard C integer type.
132
R. David Murray87e20742009-05-23 01:30:26 +0000133- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
134 Patch by Farhan Ahmad, test by Marcin Bachry.
135
Antoine Pitrou6e610062009-05-15 17:04:50 +0000136- Issue #2116: Weak references and weak dictionaries now support copy()ing and
137 deepcopy()ing.
138

142
Antoine Pitrou2ca24f02009-05-14 21:30:46 +0000143- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
144
Antoine Pitroue4501852009-05-14 18:55:55 +0000145- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
146 library. This means, for example, that opening an UTF-16 text file in
147 append mode doesn't add a BOM at the end of the file if the file isn't
148 empty.
149
R. David Murray74b89242009-05-13 17:33:03 +0000150- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
151 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
152 corrects a pydoc regression.
153
R. David Murray99352742009-05-07 18:24:38 +0000154- Issue 5955: aifc's close method did not close the file it wrapped,
155 now it does. This also means getfp method now returns the real fp.
156
Benjamin Peterson932073a2009-05-23 16:14:33 +0000157Installation
158------------
159
160- Issue #6047: fullinstall has been removed because Python 3's executable will
161 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +0000162

Brett Cannon1262e7c2009-05-11 01:47:11 +0000184Tests
185-----
186
187- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
188 tests on darwin even when the OS was installed on a case-sensitive

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000197
198Core and Builtins
199-----------------
200
Mark Dickinson865e01a2009-05-07 16:37:01 +0000201- Issue #5914: Add new C API function PyOS_string_to_double, and
202 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
203
Eric Smith741191f2009-05-06 13:08:15 +0000204- Issue #3382: float.__format__, complex.__format__, and %-formatting
205 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
206 affects nan -> NAN and inf -> INF.
207
Mark Hammond5a607a32009-05-06 08:04:54 +0000208- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
209 in all operations, including splitdrive, split, etc. splitunc() now issues
210 a PendingDeprecation warning.
211
Eric Smith63376222009-05-05 14:04:18 +0000212- Issue #5920: For float.__format__, change the behavior with the
213 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
214 to be like 'g' but with at least one decimal point and with a
215 default precision of 12. Previously, the behavior the same but with
216 a default precision of 6. This more closely matches str(), and
217 reduces surprises when adding alignment flags to the empty
218 presentation type. This also affects the new complex.__format__ in
219 the same way.
220
Martin v. Löwis011e8422009-05-05 04:43:17 +0000221- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
222
R. David Murrayb18500d2009-05-04 22:59:07 +0000223- Issue #5890: in subclasses of 'property' the __doc__ attribute was
224 shadowed by classtype's, even if it was None. property now
225 inserts the __doc__ into the subclass instance __dict__.
226
Antoine Pitrou244651a2009-05-04 18:56:13 +0000227- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
228 sequences. Patch by Nick Barnes and Victor Stinner.
229
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000230- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000231
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000232- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
233 received a new method, detach(). detach() disconnects the underlying stream
234 from the buffer or text IO and returns it.
235
Mark Dickinson33841c32009-05-01 15:37:04 +0000236- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
237 floats with absolute value over 1e50. Also remove length
238 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
239 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000240
Eric Smith741191f2009-05-06 13:08:15 +0000241- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000242 format(complex(1, 2./3), '.5') now produces a sensible result.
243
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000244- Issue #5864: Fix empty format code formatting for floats so that it
245 never gives more than the requested number of significant digits.
246
Eric Smith6dc46f52009-04-27 20:39:49 +0000247- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
248 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
249
Eric Smithcc32a112009-04-26 21:35:14 +0000250- Issue #5835: Deprecate PyOS_ascii_formatd.
251
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000252- Issue #4971: Fix titlecase for characters that are their own
253 titlecase, but not their own uppercase.
254
Benjamin Peterson193152c2009-04-25 01:08:45 +0000255- Issue #5283: Setting __class__ in __del__ caused a segfault.
256
Mark Dickinsonad476da2009-04-23 19:14:16 +0000257- Issue #5816: complex(repr(z)) now recovers z exactly, even when
258 z involves nans, infs or negative zeros.
259
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000260- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000261
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000262- Issue #1869 (and many duplicates): make round(x, n) correctly
263 rounded for a float x, by using the decimal <-> binary conversions
264 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
265 consistently agrees with format(x, '.2f').
266
Benjamin Petersonae937c02009-04-18 20:54:08 +0000267- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
268 some builtin types.
269
Eric Smith0923d1d2009-04-16 20:16:10 +0000270- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
271
Eric Smith35e84722009-04-16 20:21:28 +0000272- Issue #5515: str.format() type 'n' combined with commas and leading
273 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000274
275- Implement PEP 378, Format Specifier for Thousands Separator, for
276 floats.
277
Mark Dickinson3370cce2009-04-17 22:40:53 +0000278- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000279 1e11, not 1e12. This avoids printing 13 significant digits in
280 situations where only 12 of them are correct. Example problem
281 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
282 long time.)
283
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000284- Issue #1580: On most platforms, use a 'short' float repr: for a
285 finite float x, repr(x) now outputs a string based on the shortest
286 sequence of decimal digits that rounds to x. Previous behaviour was
287 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000288 Another minor difference is that the new repr switches to
289 exponential notation at 1e16 instead of the previous 1e17; this
290 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000291
292 There's a new sys attribute sys.float_repr_style, which takes
293 the value 'short' to indicate that we're using short float repr,
294 and 'legacy' if the short float repr isn't available for one
295 reason or another.
296
297 The float repr change involves incorporating David Gay's 'perfect
298 rounding' code into the Python core (it's in Python/dtoa.c). As a
299 secondary consequence, all string-to-float and float-to-string
300 conversions (including all float formatting operations) will be
301 correctly rounded on these platforms.
302
303 See issue 1580 discussions for details of platforms for which
304 this change does not apply.
305
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000306- Issue #5759: float() didn't call __float__ on str subclasses.
307
Georg Brandlabc38772009-04-12 15:51:51 +0000308- The string.maketrans() function is deprecated; there is a new static method
309 maketrans() on the bytes and bytearray classes. This removes confusion about
310 the types string.maketrans() is supposed to work with, and mirrors the
311 methods available on the str class.
312
R. David Murraydc6da8a2009-04-09 22:16:43 +0000313- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

623 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
624 evaluation loop is compiled with a new dispatch mechanism which gives
625 speedups of up to 20%, depending on the system, on various benchmarks.

636
Mark Dickinson8055afd2009-01-17 10:04:45 +0000637- Issue #4910: Rename nb_long slot to nb_reserved, and change its
638 type to (void *).
639
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000640- Issue #4935: The overflow checking code in the expandtabs() method common
641 to str, bytes and bytearray could be optimized away by the compiler, letting
642 the interpreter segfault instead of raising an error.
643
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000644- Issue #3720: Fix a crash when an iterator modifies its class and removes its
645 __next__ method.
646
Mark Dickinsone5e298f2009-01-12 20:49:19 +0000647- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

654
Antoine Pitrouab868312009-01-10 15:40:25 +0000655- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
656 common cases are optimized thanks to a dedicated fast path and a moderate
657 amount of loop unrolling.
658
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000659- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
660 collecting the oldest generation) so that allocating lots of objects without
661 destroying them does not show quadratic performance. Based on a proposal by
662 Martin von Löwis at
663 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
664
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000665- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000666 having been closed (for instance, a read() call could return some
667 previously buffered data). Patch by Dmitry Vasiliev.
668
Antoine Pitrou05608432009-01-09 18:53:14 +0000669- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
670 flag to work properly. Furthermore, when specifying -u, the text stdout
671 and stderr streams have line-by-line buffering enabled (the default being
672 to buffer arbitrary chunks of data).
673
Raymond Hettinger35631532009-01-09 03:58:09 +0000674- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
675 instead of ints (reducing its size from 4 to 8 times thereby reducing
676 Python's overall memory).
677
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000678- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
679 an existing .py counterpart, override the co_filename attributes of all
680 code objects if the original filename is obsolete (which can happen if the
681 file has been renamed, moved, or if it is accessed through different paths).
682 Patch by Ziga Seilnacht and Jean-Paul Calderone.
683
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000684- Issue #4580: Fix slicing of memoryviews when the item size is greater than
685 one byte. Also fixes the meaning of len() so that it returns the number of
686 items, rather than the size in bytes.
687
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000688- Issue #4075: Use OutputDebugStringW in Py_FatalError.
689
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000690- Issue #4747: When the terminal does not use utf-8, executing a script with
691 non-ascii characters in its name could fail with a "SyntaxError: None" error.
692
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000693- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

698
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000699- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
700 where the tp_hash and tp_dict slots are both NULL.
701
Georg Brandlccc47b62008-12-28 11:44:14 +0000702- Issue #4759: None is now allowed as the first argument of

704
Skip Montanaro80072cb2008-12-23 03:51:14 +0000705- Added test case to ensure attempts to read from a file opened for writing

712
Antoine Pitrou621601a2008-12-17 23:18:19 +0000713- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

721 failures on OS X.
722
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000723- Issue #4597: Fixed several opcodes that weren't always propagating

725
726- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000727 context manager returns a value that cannot be converted to a bool.
728
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000729- Issue #4445: Replace "sizeof(PyBytesObject)" with
730 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
731 bytes instances. On a typical machine this saves 3 bytes of memory
732 (on average) per allocation of a bytes instance.
733
Christian Heimesa872de52008-12-05 08:26:55 +0000734- Issue #4533: File read operation was dreadfully slow due to a slowly
735 growing read buffer. Fixed by using the same growth rate algorithm as
736 Python 2.x.
737
Antoine Pitrou5504e892008-12-06 21:27:53 +0000738- Issue #4509: Various issues surrounding resize of bytearray objects to
739 which there are buffer exports (e.g. memoryview instances).
740
Georg Brandlf9734072008-12-07 15:30:06 +0000741- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
742 method on file objects with closefd=False. The file descriptor is still
743 kept open but the file object behaves like a closed file. The ``FileIO``
744 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000745
Antoine Pitroubc420402008-12-07 20:14:49 +0000746- Issue #4569: Interpreter crash when mutating a memoryview with an item size

752
Walter Dörwaldc1651a02009-05-03 22:55:55 +0000753- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
754 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
755 step. This avoids problems with counting UTF-8 bytes that ignores the effect
756 of using the replace error handler in PyUnicode_DecodeUTF8().
