12Core and Builtins
13-----------------
14
Martin v. Löwis8ed91b22009-05-29 16:22:26 +000015- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
16 of the command line.
17
Martin v. Löwisc15bdef2009-05-29 14:47:46 +000018- Issue #6012: Add cleanup support to O& argument parsing.
19
Eric Smith41669ca2009-05-23 14:23:22 +000020- Issue #6089: Fixed str.format with certain invalid field specifiers
21 that would raise SystemError.
22
Raymond Hettinger2bcde142009-05-29 04:52:27 +000023- Issue #5982: staticmethod and classmethod now expose the wrapped
24 function with __func__.
25
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +000026- Added support for multiple context managers in the same with-statement.
27 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +000028
Mark Dickinson6b1e43b2009-05-20 18:41:04 +000029- Issue #5829: complex("1e500") no longer raises OverflowError. This
30 makes it consistent with float("1e500") and interpretation of real
31 and imaginary literals.
32
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +000033- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
34
R. David Murraydd226ea2009-05-13 12:27:21 +000035- Issue #5994: the marshal module now has docstrings.
36
Mark Dickinsond1ec8b22009-05-11 15:45:15 +000037- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
38 (1) inf and nan strings with trailing whitespace were incorrectly
39 rejected; (2) parsing of strings representing infinities and nans
40 was locale aware; and (3) the interpretation of fromhex('-nan')
41 didn't match that of float('-nan').

44-------
45
Martin v. Löwisb6a748b2009-05-29 15:23:17 +000046- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
47
R. David Murrayfb123912009-05-28 18:19:00 +000048- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
49
R. David Murray1f1b9d32009-05-27 20:56:59 +000050- Issue #6121: pydoc now ignores leading and trailing spaces in the
51 argument to the 'help' function.
52
Georg Brandlfaf41492009-05-26 18:31:11 +000053- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
54 arguments for strings with a space in them.
55
Raymond Hettinger089ba7f2009-05-27 00:38:24 +000056- collections.namedtuple() was not working with the following field
57 names: cls, self, tuple, itemgetter, and property.
58
Benjamin Peterson14a3dd72009-05-25 00:51:58 +000059- In unittest, using a skipping decorator on a class is now equivalent to
60 skipping every test on the class. The ClassTestSuite class has been removed.
61
Martin v. Löwis70ccd162009-05-24 19:47:22 +000062- Issue #6050: Don't fail extracting a directory from a zipfile if
63 the directory already exists.
64
Antoine Pitrou61f77b52009-05-24 15:46:13 +000065- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
66 than an int, which makes some operations possible under 64-bit Linux (e.g.
67 DN_MULTISHOT with F_NOTIFY).
68
Antoine Pitrou716c4442009-05-23 19:04:03 +000069- Issue #5761: Add the name of the underlying file to the repr() of various

71
R. David Murraycaa27b72009-05-23 18:49:56 +000072- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
73 by Musashi Tamura, tests by Marcin Bachry.
74
Antoine Pitrouc3ee1662009-05-23 16:02:33 +000075- Issue #1983: Fix functions taking or returning a process identifier to use
76 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
77 a process identifier type wider than the standard C integer type.
78
R. David Murray87e20742009-05-23 01:30:26 +000079- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

88
Antoine Pitrou2ca24f02009-05-14 21:30:46 +000089- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
90
Antoine Pitroue4501852009-05-14 18:55:55 +000091- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
92 library. This means, for example, that opening an UTF-16 text file in
93 append mode doesn't add a BOM at the end of the file if the file isn't
94 empty.
95
R. David Murray74b89242009-05-13 17:33:03 +000096- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
97 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
98 corrects a pydoc regression.
99
R. David Murray99352742009-05-07 18:24:38 +0000100- Issue 5955: aifc's close method did not close the file it wrapped,
101 now it does. This also means getfp method now returns the real fp.
102
Benjamin Peterson932073a2009-05-23 16:14:33 +0000103Installation
104------------
105
106- Issue #6047: fullinstall has been removed because Python 3's executable will
107 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +0000108
Ronald Oussorenbe7149e2009-05-26 21:39:08 +0000109- Lib/smtpd.py is no longer installed as a script.

Benjamin Peterson3dc22e82009-05-23 17:09:43 +0000120
Antoine Pitrou20327222009-05-24 20:39:11 +0000121Build
122-----
123
124- Issue #3585: Add pkg-config support. It creates a python-2.7.pc file

127
Brett Cannon1262e7c2009-05-11 01:47:11 +0000128Tests
129-----
130
131- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
132 tests on darwin even when the OS was installed on a case-sensitive
133 filesystem. Also fixed tests that should not be run when
134 sys.dont_write_bytecode is true.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000137What's New in Python 3.1 beta 1?
138================================
139
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000140*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000141
142Core and Builtins
143-----------------
144
Mark Dickinson865e01a2009-05-07 16:37:01 +0000145- Issue #5914: Add new C API function PyOS_string_to_double, and
146 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
147
Eric Smith741191f2009-05-06 13:08:15 +0000148- Issue #3382: float.__format__, complex.__format__, and %-formatting
149 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
150 affects nan -> NAN and inf -> INF.
151
Mark Hammond5a607a32009-05-06 08:04:54 +0000152- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
153 in all operations, including splitdrive, split, etc. splitunc() now issues
154 a PendingDeprecation warning.
155
Eric Smith63376222009-05-05 14:04:18 +0000156- Issue #5920: For float.__format__, change the behavior with the
157 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
158 to be like 'g' but with at least one decimal point and with a
159 default precision of 12. Previously, the behavior the same but with
160 a default precision of 6. This more closely matches str(), and
161 reduces surprises when adding alignment flags to the empty
162 presentation type. This also affects the new complex.__format__ in
163 the same way.
164
Martin v. Löwis011e8422009-05-05 04:43:17 +0000165- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
166
R. David Murrayb18500d2009-05-04 22:59:07 +0000167- Issue #5890: in subclasses of 'property' the __doc__ attribute was
168 shadowed by classtype's, even if it was None. property now
169 inserts the __doc__ into the subclass instance __dict__.
170
Antoine Pitrou244651a2009-05-04 18:56:13 +0000171- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
172 sequences. Patch by Nick Barnes and Victor Stinner.
173
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000174- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000175
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000176- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
177 received a new method, detach(). detach() disconnects the underlying stream
178 from the buffer or text IO and returns it.
179
Mark Dickinson33841c32009-05-01 15:37:04 +0000180- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
181 floats with absolute value over 1e50. Also remove length
182 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
183 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000184
Eric Smith741191f2009-05-06 13:08:15 +0000185- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000186 format(complex(1, 2./3), '.5') now produces a sensible result.
187
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000188- Issue #5864: Fix empty format code formatting for floats so that it
189 never gives more than the requested number of significant digits.
190
Eric Smith6dc46f52009-04-27 20:39:49 +0000191- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
192 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
193
Eric Smithcc32a112009-04-26 21:35:14 +0000194- Issue #5835: Deprecate PyOS_ascii_formatd.
195
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000196- Issue #4971: Fix titlecase for characters that are their own
197 titlecase, but not their own uppercase.
198
Benjamin Peterson193152c2009-04-25 01:08:45 +0000199- Issue #5283: Setting __class__ in __del__ caused a segfault.
200
Mark Dickinsonad476da2009-04-23 19:14:16 +0000201- Issue #5816: complex(repr(z)) now recovers z exactly, even when
202 z involves nans, infs or negative zeros.
203
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000204- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000205
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000206- Issue #1869 (and many duplicates): make round(x, n) correctly
207 rounded for a float x, by using the decimal <-> binary conversions
208 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
209 consistently agrees with format(x, '.2f').
210
Benjamin Petersonae937c02009-04-18 20:54:08 +0000211- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
212 some builtin types.
213
Eric Smith0923d1d2009-04-16 20:16:10 +0000214- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
215
Eric Smith35e84722009-04-16 20:21:28 +0000216- Issue #5515: str.format() type 'n' combined with commas and leading
217 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000218
219- Implement PEP 378, Format Specifier for Thousands Separator, for
220 floats.
221
Mark Dickinson3370cce2009-04-17 22:40:53 +0000222- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000223 1e11, not 1e12. This avoids printing 13 significant digits in
224 situations where only 12 of them are correct. Example problem
225 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
226 long time.)
227
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000228- Issue #1580: On most platforms, use a 'short' float repr: for a
229 finite float x, repr(x) now outputs a string based on the shortest
230 sequence of decimal digits that rounds to x. Previous behaviour was
231 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000232 Another minor difference is that the new repr switches to
233 exponential notation at 1e16 instead of the previous 1e17; this
234 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000235
236 There's a new sys attribute sys.float_repr_style, which takes
237 the value 'short' to indicate that we're using short float repr,
238 and 'legacy' if the short float repr isn't available for one
239 reason or another.
240
241 The float repr change involves incorporating David Gay's 'perfect
242 rounding' code into the Python core (it's in Python/dtoa.c). As a
243 secondary consequence, all string-to-float and float-to-string
244 conversions (including all float formatting operations) will be
245 correctly rounded on these platforms.
246
247 See issue 1580 discussions for details of platforms for which
248 this change does not apply.
249
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000250- Issue #5759: float() didn't call __float__ on str subclasses.
251
Georg Brandlabc38772009-04-12 15:51:51 +0000252- The string.maketrans() function is deprecated; there is a new static method
253 maketrans() on the bytes and bytearray classes. This removes confusion about
254 the types string.maketrans() is supposed to work with, and mirrors the
255 methods available on the str class.
256
R. David Murraydc6da8a2009-04-09 22:16:43 +0000257- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
258 its clarity and its speed.
259
Matthias Klose091c7b12009-04-07 13:24:27 +0000260- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
261 to avoid compiler warnings.
262
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000263- Issue #3739: The unicode-internal encoder now reports the number of characters
264 consumed like any other encoder (instead of the number of bytes).
265
Benjamin Peterson0b4915e2009-04-25 21:11:45 +0000266Installation

R. David Murray9e94ddf2009-04-13 17:06:33 +0000342- Issue #1161031: fix readwrite select flag handling: POLLPRI now
343 results in a handle_expt_event call, not handle_read_event, and POLLERR
344 and POLLNVAL now call handle_close, not handle_expt_event. Also,
345 dispatcher now has an 'ignore_log_types' attribute for suppressing

Benjamin Peterson7fe98532009-04-02 00:33:55 +0000401- Issue #5499: The 'c' code for argument parsing functions now only accepts a
402 byte, and the 'C' code only accepts a unicode character.
403
Georg Brandl406b3d82009-04-11 21:24:37 +0000404- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"

420
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000421- Issue #4688: Add a heuristic so that tuples and dicts containing only
422 untrackable objects are not tracked by the garbage collector. This can
423 reduce the size of collections and therefore the garbage collection overhead
424 on long-running programs, depending on their particular use of datatypes.

Lars Gustäbel42e00912009-03-22 20:34:29 +0000494- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
495 forever on incomplete input. That caused tarfile.open() to hang when used
496 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
497 partial bzip2 compressed data.
498
Mark Dickinson79f52032009-03-17 23:12:51 +0000499- Issue #2110: Add support for thousands separator and 'n' type

614 flag to work properly. Furthermore, when specifying -u, the text stdout
615 and stderr streams have line-by-line buffering enabled (the default being
616 to buffer arbitrary chunks of data).
617
Raymond Hettinger35631532009-01-09 03:58:09 +0000618- The internal table, _PyLong_DigitValue, is now an array of unsigned chars

624 code objects if the original filename is obsolete (which can happen if the
625 file has been renamed, moved, or if it is accessed through different paths).

674 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for

688 object also got a new readonly attribute ``closefd``.

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