12Core and Builtins
13-----------------
14
Eric Smith41669ca2009-05-23 14:23:22 +000015- Issue #6089: Fixed str.format with certain invalid field specifiers
16 that would raise SystemError.
17
Georg Brandl0c315622009-05-25 21:10:36 +000018- Added support for multiple context managers in the same with statement.
19
Mark Dickinson6b1e43b2009-05-20 18:41:04 +000020- Issue #5829: complex("1e500") no longer raises OverflowError. This
21 makes it consistent with float("1e500") and interpretation of real
22 and imaginary literals.
23
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +000024- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
25
R. David Murraydd226ea2009-05-13 12:27:21 +000026- Issue #5994: the marshal module now has docstrings.
27
Mark Dickinsond1ec8b22009-05-11 15:45:15 +000028- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
29 (1) inf and nan strings with trailing whitespace were incorrectly
30 rejected; (2) parsing of strings representing infinities and nans
31 was locale aware; and (3) the interpretation of fromhex('-nan')
32 didn't match that of float('-nan').
33

35-------
36
Georg Brandlfaf41492009-05-26 18:31:11 +000037- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
38 arguments for strings with a space in them.
39
Benjamin Peterson14a3dd72009-05-25 00:51:58 +000040- In unittest, using a skipping decorator on a class is now equivalent to
41 skipping every test on the class. The ClassTestSuite class has been removed.
42
Martin v. Löwis70ccd162009-05-24 19:47:22 +000043- Issue #6050: Don't fail extracting a directory from a zipfile if
44 the directory already exists.
45
Antoine Pitrou61f77b52009-05-24 15:46:13 +000046- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
47 than an int, which makes some operations possible under 64-bit Linux (e.g.
48 DN_MULTISHOT with F_NOTIFY).
49
Antoine Pitrou716c4442009-05-23 19:04:03 +000050- Issue #5761: Add the name of the underlying file to the repr() of various
51 IO objects.
52
R. David Murraycaa27b72009-05-23 18:49:56 +000053- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
54 by Musashi Tamura, tests by Marcin Bachry.
55
Antoine Pitrouc3ee1662009-05-23 16:02:33 +000056- Issue #1983: Fix functions taking or returning a process identifier to use
57 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
58 a process identifier type wider than the standard C integer type.
59
R. David Murray87e20742009-05-23 01:30:26 +000060- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
61 Patch by Farhan Ahmad, test by Marcin Bachry.
62
Antoine Pitrou6e610062009-05-15 17:04:50 +000063- Issue #2116: Weak references and weak dictionaries now support copy()ing and
64 deepcopy()ing.
65
Antoine Pitrouc1d09362009-05-15 12:15:51 +000066- Issue #1655: Make imaplib IPv6-capable. Patch by Derek Morr.
67
Antoine Pitrou37d1c182009-05-14 21:54:00 +000068- Issue #5918: Fix a crash in the parser module.
69
Antoine Pitrou2ca24f02009-05-14 21:30:46 +000070- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
71
Antoine Pitroue4501852009-05-14 18:55:55 +000072- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
73 library. This means, for example, that opening an UTF-16 text file in
74 append mode doesn't add a BOM at the end of the file if the file isn't
75 empty.
76
R. David Murray74b89242009-05-13 17:33:03 +000077- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
78 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
79 corrects a pydoc regression.
80
R. David Murray99352742009-05-07 18:24:38 +000081- Issue 5955: aifc's close method did not close the file it wrapped,
82 now it does. This also means getfp method now returns the real fp.
83
Benjamin Peterson932073a2009-05-23 16:14:33 +000084Installation
85------------
86
87- Issue #6047: fullinstall has been removed because Python 3's executable will
88 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +000089
Martin v. Löwisdb1c3992009-05-23 10:38:26 +000090Extension Modules
91-----------------
92
93- Issue #6093: Fix off-by-one error in locale.strxfrm.
94
Benjamin Peterson744af442009-05-23 18:51:49 +000095- The _functools and _locale modules are now built into the libpython shared
96 library instead of as extension modules.
Benjamin Peterson3dc22e82009-05-23 17:09:43 +000097
Antoine Pitrou20327222009-05-24 20:39:11 +000098Build
99-----
100
101- Issue #3585: Add pkg-config support. It creates a python-2.7.pc file
102 and a python3.pc symlink in the $(LIBDIR)/pkgconfig directory. Patch by
103 Clinton Roy.
104
Brett Cannon1262e7c2009-05-11 01:47:11 +0000105Tests
106-----
107
108- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
109 tests on darwin even when the OS was installed on a case-sensitive
110 filesystem. Also fixed tests that should not be run when
111 sys.dont_write_bytecode is true.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000114What's New in Python 3.1 beta 1?
115================================
116
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000117*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000118
119Core and Builtins
120-----------------
121
Mark Dickinson865e01a2009-05-07 16:37:01 +0000122- Issue #5914: Add new C API function PyOS_string_to_double, and
123 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
124
Eric Smith741191f2009-05-06 13:08:15 +0000125- Issue #3382: float.__format__, complex.__format__, and %-formatting
126 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
127 affects nan -> NAN and inf -> INF.
128
Mark Hammond5a607a32009-05-06 08:04:54 +0000129- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
130 in all operations, including splitdrive, split, etc. splitunc() now issues
131 a PendingDeprecation warning.
132
Eric Smith63376222009-05-05 14:04:18 +0000133- Issue #5920: For float.__format__, change the behavior with the
134 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
135 to be like 'g' but with at least one decimal point and with a
136 default precision of 12. Previously, the behavior the same but with
137 a default precision of 6. This more closely matches str(), and
138 reduces surprises when adding alignment flags to the empty
139 presentation type. This also affects the new complex.__format__ in
140 the same way.
141
Martin v. Löwis011e8422009-05-05 04:43:17 +0000142- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
143
R. David Murrayb18500d2009-05-04 22:59:07 +0000144- Issue #5890: in subclasses of 'property' the __doc__ attribute was
145 shadowed by classtype's, even if it was None. property now
146 inserts the __doc__ into the subclass instance __dict__.
147
Antoine Pitrou244651a2009-05-04 18:56:13 +0000148- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
149 sequences. Patch by Nick Barnes and Victor Stinner.
150
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000151- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000152
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000153- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
154 received a new method, detach(). detach() disconnects the underlying stream
155 from the buffer or text IO and returns it.
156
Mark Dickinson33841c32009-05-01 15:37:04 +0000157- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
158 floats with absolute value over 1e50. Also remove length
159 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
160 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000161
Eric Smith741191f2009-05-06 13:08:15 +0000162- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000163 format(complex(1, 2./3), '.5') now produces a sensible result.
164
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000165- Issue #5864: Fix empty format code formatting for floats so that it
166 never gives more than the requested number of significant digits.
167
Eric Smith6dc46f52009-04-27 20:39:49 +0000168- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
169 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
170
Eric Smithcc32a112009-04-26 21:35:14 +0000171- Issue #5835: Deprecate PyOS_ascii_formatd.
172
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000173- Issue #4971: Fix titlecase for characters that are their own
174 titlecase, but not their own uppercase.
175
Benjamin Peterson193152c2009-04-25 01:08:45 +0000176- Issue #5283: Setting __class__ in __del__ caused a segfault.
177
Mark Dickinsonad476da2009-04-23 19:14:16 +0000178- Issue #5816: complex(repr(z)) now recovers z exactly, even when
179 z involves nans, infs or negative zeros.
180
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000181- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000182
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000183- Issue #1869 (and many duplicates): make round(x, n) correctly
184 rounded for a float x, by using the decimal <-> binary conversions
185 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
186 consistently agrees with format(x, '.2f').
187
Benjamin Petersonae937c02009-04-18 20:54:08 +0000188- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
189 some builtin types.
190
Eric Smith0923d1d2009-04-16 20:16:10 +0000191- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
192
Eric Smith35e84722009-04-16 20:21:28 +0000193- Issue #5515: str.format() type 'n' combined with commas and leading
194 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000195
196- Implement PEP 378, Format Specifier for Thousands Separator, for
197 floats.
198
Mark Dickinson3370cce2009-04-17 22:40:53 +0000199- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000200 1e11, not 1e12. This avoids printing 13 significant digits in
201 situations where only 12 of them are correct. Example problem
202 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
203 long time.)
204
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000205- Issue #1580: On most platforms, use a 'short' float repr: for a
206 finite float x, repr(x) now outputs a string based on the shortest
207 sequence of decimal digits that rounds to x. Previous behaviour was
208 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000209 Another minor difference is that the new repr switches to
210 exponential notation at 1e16 instead of the previous 1e17; this
211 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000212
213 There's a new sys attribute sys.float_repr_style, which takes
214 the value 'short' to indicate that we're using short float repr,
215 and 'legacy' if the short float repr isn't available for one
216 reason or another.
217
218 The float repr change involves incorporating David Gay's 'perfect
219 rounding' code into the Python core (it's in Python/dtoa.c). As a
220 secondary consequence, all string-to-float and float-to-string
221 conversions (including all float formatting operations) will be
222 correctly rounded on these platforms.
223
224 See issue 1580 discussions for details of platforms for which
225 this change does not apply.
226
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000227- Issue #5759: float() didn't call __float__ on str subclasses.
228
Georg Brandlabc38772009-04-12 15:51:51 +0000229- The string.maketrans() function is deprecated; there is a new static method
230 maketrans() on the bytes and bytearray classes. This removes confusion about
231 the types string.maketrans() is supposed to work with, and mirrors the
232 methods available on the str class.
233
R. David Murraydc6da8a2009-04-09 22:16:43 +0000234- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
235 its clarity and its speed.
236
Matthias Klose091c7b12009-04-07 13:24:27 +0000237- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
238 to avoid compiler warnings.
239
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000240- Issue #3739: The unicode-internal encoder now reports the number of characters
241 consumed like any other encoder (instead of the number of bytes).
242
Benjamin Peterson0b4915e2009-04-25 21:11:45 +0000243Installation

397 reduce the size of collections and therefore the garbage collection overhead
398 on long-running programs, depending on their particular use of datatypes.

469 forever on incomplete input. That caused tarfile.open() to hang when used
470 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
471 partial bzip2 compressed data.
472
Mark Dickinson79f52032009-03-17 23:12:51 +0000473- Issue #2110: Add support for thousands separator and 'n' type

588 flag to work properly. Furthermore, when specifying -u, the text stdout
589 and stderr streams have line-by-line buffering enabled (the default being
590 to buffer arbitrary chunks of data).
591
Raymond Hettinger35631532009-01-09 03:58:09 +0000592- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
593 instead of ints (reducing its size from 4 to 8 times thereby reducing
594 Python's overall memory).
595
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000596- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
597 an existing .py counterpart, override the co_filename attributes of all

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