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
Mark Dickinson6b1e43b2009-05-20 18:41:04 +000018- Issue #5829: complex("1e500") no longer raises OverflowError. This
19 makes it consistent with float("1e500") and interpretation of real
20 and imaginary literals.
21
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +000022- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
23
R. David Murraydd226ea2009-05-13 12:27:21 +000024- Issue #5994: the marshal module now has docstrings.
25
Mark Dickinsond1ec8b22009-05-11 15:45:15 +000026- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
27 (1) inf and nan strings with trailing whitespace were incorrectly
28 rejected; (2) parsing of strings representing infinities and nans
29 was locale aware; and (3) the interpretation of fromhex('-nan')
30 didn't match that of float('-nan').

33-------
34
Martin v. Löwis70ccd162009-05-24 19:47:22 +000035- Issue #6050: Don't fail extracting a directory from a zipfile if
36 the directory already exists.
37
Antoine Pitrou61f77b52009-05-24 15:46:13 +000038- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
39 than an int, which makes some operations possible under 64-bit Linux (e.g.
40 DN_MULTISHOT with F_NOTIFY).
41
Antoine Pitrou716c4442009-05-23 19:04:03 +000042- Issue #5761: Add the name of the underlying file to the repr() of various
43 IO objects.
44
R. David Murraycaa27b72009-05-23 18:49:56 +000045- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
46 by Musashi Tamura, tests by Marcin Bachry.
47
Antoine Pitrouc3ee1662009-05-23 16:02:33 +000048- Issue #1983: Fix functions taking or returning a process identifier to use
49 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
50 a process identifier type wider than the standard C integer type.
51
R. David Murray87e20742009-05-23 01:30:26 +000052- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
53 Patch by Farhan Ahmad, test by Marcin Bachry.
54
Antoine Pitrou6e610062009-05-15 17:04:50 +000055- Issue #2116: Weak references and weak dictionaries now support copy()ing and
56 deepcopy()ing.
57
Antoine Pitrouc1d09362009-05-15 12:15:51 +000058- Issue #1655: Make imaplib IPv6-capable. Patch by Derek Morr.

61
Antoine Pitrou2ca24f02009-05-14 21:30:46 +000062- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
63
Antoine Pitroue4501852009-05-14 18:55:55 +000064- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
65 library. This means, for example, that opening an UTF-16 text file in
66 append mode doesn't add a BOM at the end of the file if the file isn't
67 empty.
68
R. David Murray74b89242009-05-13 17:33:03 +000069- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
70 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
71 corrects a pydoc regression.
72
R. David Murray99352742009-05-07 18:24:38 +000073- Issue 5955: aifc's close method did not close the file it wrapped,
74 now it does. This also means getfp method now returns the real fp.
75
Benjamin Peterson932073a2009-05-23 16:14:33 +000076Installation
77------------
78
79- Issue #6047: fullinstall has been removed because Python 3's executable will
80 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +000081
Martin v. Löwisdb1c3992009-05-23 10:38:26 +000082Extension Modules

86
Benjamin Peterson744af442009-05-23 18:51:49 +000087- The _functools and _locale modules are now built into the libpython shared
88 library instead of as extension modules.
Benjamin Peterson3dc22e82009-05-23 17:09:43 +000089
Brett Cannon1262e7c2009-05-11 01:47:11 +000090Tests
91-----
92
93- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
94 tests on darwin even when the OS was installed on a case-sensitive
95 filesystem. Also fixed tests that should not be run when
96 sys.dont_write_bytecode is true.

Benjamin Petersonbd35b032009-04-04 23:16:41 +000099What's New in Python 3.1 beta 1?
100================================
101
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000102*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000103
104Core and Builtins
105-----------------
106
Mark Dickinson865e01a2009-05-07 16:37:01 +0000107- Issue #5914: Add new C API function PyOS_string_to_double, and
108 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
109
Eric Smith741191f2009-05-06 13:08:15 +0000110- Issue #3382: float.__format__, complex.__format__, and %-formatting
111 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
112 affects nan -> NAN and inf -> INF.
113
Mark Hammond5a607a32009-05-06 08:04:54 +0000114- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
115 in all operations, including splitdrive, split, etc. splitunc() now issues
116 a PendingDeprecation warning.
117
Eric Smith63376222009-05-05 14:04:18 +0000118- Issue #5920: For float.__format__, change the behavior with the
119 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
120 to be like 'g' but with at least one decimal point and with a
121 default precision of 12. Previously, the behavior the same but with
122 a default precision of 6. This more closely matches str(), and
123 reduces surprises when adding alignment flags to the empty
124 presentation type. This also affects the new complex.__format__ in
125 the same way.
126
Martin v. Löwis011e8422009-05-05 04:43:17 +0000127- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
128
R. David Murrayb18500d2009-05-04 22:59:07 +0000129- Issue #5890: in subclasses of 'property' the __doc__ attribute was
130 shadowed by classtype's, even if it was None. property now
131 inserts the __doc__ into the subclass instance __dict__.
132
Antoine Pitrou244651a2009-05-04 18:56:13 +0000133- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
134 sequences. Patch by Nick Barnes and Victor Stinner.
135
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000136- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000137
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000138- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
139 received a new method, detach(). detach() disconnects the underlying stream
140 from the buffer or text IO and returns it.
141
Mark Dickinson33841c32009-05-01 15:37:04 +0000142- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
143 floats with absolute value over 1e50. Also remove length
144 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
145 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000146
Eric Smith741191f2009-05-06 13:08:15 +0000147- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000148 format(complex(1, 2./3), '.5') now produces a sensible result.
149
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000150- Issue #5864: Fix empty format code formatting for floats so that it
151 never gives more than the requested number of significant digits.
152
Eric Smith6dc46f52009-04-27 20:39:49 +0000153- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
154 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
155
Eric Smithcc32a112009-04-26 21:35:14 +0000156- Issue #5835: Deprecate PyOS_ascii_formatd.
157
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000158- Issue #4971: Fix titlecase for characters that are their own
159 titlecase, but not their own uppercase.
160
Benjamin Peterson193152c2009-04-25 01:08:45 +0000161- Issue #5283: Setting __class__ in __del__ caused a segfault.
162
Mark Dickinsonad476da2009-04-23 19:14:16 +0000163- Issue #5816: complex(repr(z)) now recovers z exactly, even when
164 z involves nans, infs or negative zeros.
165
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000166- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000167
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000168- Issue #1869 (and many duplicates): make round(x, n) correctly
169 rounded for a float x, by using the decimal <-> binary conversions
170 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
171 consistently agrees with format(x, '.2f').
172
Benjamin Petersonae937c02009-04-18 20:54:08 +0000173- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
174 some builtin types.
175
Eric Smith0923d1d2009-04-16 20:16:10 +0000176- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
177
Eric Smith35e84722009-04-16 20:21:28 +0000178- Issue #5515: str.format() type 'n' combined with commas and leading
179 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000180
181- Implement PEP 378, Format Specifier for Thousands Separator, for
182 floats.
183
Mark Dickinson3370cce2009-04-17 22:40:53 +0000184- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000185 1e11, not 1e12. This avoids printing 13 significant digits in
186 situations where only 12 of them are correct. Example problem
187 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
188 long time.)
189
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000190- Issue #1580: On most platforms, use a 'short' float repr: for a
191 finite float x, repr(x) now outputs a string based on the shortest
192 sequence of decimal digits that rounds to x. Previous behaviour was
193 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000194 Another minor difference is that the new repr switches to
195 exponential notation at 1e16 instead of the previous 1e17; this
196 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000197
198 There's a new sys attribute sys.float_repr_style, which takes
199 the value 'short' to indicate that we're using short float repr,
200 and 'legacy' if the short float repr isn't available for one
201 reason or another.
202
203 The float repr change involves incorporating David Gay's 'perfect
204 rounding' code into the Python core (it's in Python/dtoa.c). As a
205 secondary consequence, all string-to-float and float-to-string
206 conversions (including all float formatting operations) will be
207 correctly rounded on these platforms.
208
209 See issue 1580 discussions for details of platforms for which
210 this change does not apply.
211
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000212- Issue #5759: float() didn't call __float__ on str subclasses.
213
Georg Brandlabc38772009-04-12 15:51:51 +0000214- The string.maketrans() function is deprecated; there is a new static method
215 maketrans() on the bytes and bytearray classes. This removes confusion about
216 the types string.maketrans() is supposed to work with, and mirrors the
217 methods available on the str class.
218
R. David Murraydc6da8a2009-04-09 22:16:43 +0000219- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
220 its clarity and its speed.
221
Matthias Klose091c7b12009-04-07 13:24:27 +0000222- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
223 to avoid compiler warnings.
224
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000225- Issue #3739: The unicode-internal encoder now reports the number of characters
226 consumed like any other encoder (instead of the number of bytes).
227

241
Thomas Heller00cfc372009-05-05 19:04:40 +0000242- Issue #4875: On win32, ctypes.util.find_library does no longer

Benjamin Peterson8f76b492009-04-03 22:22:42 +0000358- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
359
Benjamin Peterson7fe98532009-04-02 00:33:55 +0000360- Issue #5499: The 'c' code for argument parsing functions now only accepts a
361 byte, and the 'C' code only accepts a unicode character.
362
Georg Brandl406b3d82009-04-11 21:24:37 +0000363- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
364 when hitting the recursion limit under certain circumstances.
365
Brett Cannon0759dd62009-04-01 18:13:07 +0000366- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
367
Georg Brandlab6f2f62009-03-31 04:16:10 +0000368- Fix a segfault when running test_exceptions with coverage, caused by
369 insufficient checks in accessors of Exception.__context__.
370
Guido van Rossum0ad59d42009-03-30 22:01:35 +0000371- Issue #5604: non-ASCII characters in module name passed to
372 imp.find_module() were converted to UTF-8 while the path is
373 converted to the default filesystem encoding, causing nonsense.
374
Benjamin Peterson09832742009-03-26 17:15:46 +0000375- Issue #5126: str.isprintable() returned False for space characters.

379
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000380- Issue #4688: Add a heuristic so that tuples and dicts containing only
381 untrackable objects are not tracked by the garbage collector. This can
382 reduce the size of collections and therefore the garbage collection overhead
383 on long-running programs, depending on their particular use of datatypes.
384
Mark Dickinson17e4fdd2009-03-23 18:44:57 +0000385- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

398 and sizeof(Py_UNICODE) == 2.
399
Eric Smith8ec90442009-03-14 12:29:34 +0000400- Issue #5237: Allow auto-numbered fields in str.format(). For

417 incrementalencoder and StreamWriter.
418
Georg Brandl33c28812009-04-01 23:07:29 +0000419- Issue #5656: Fix the coverage reporting when running the test suite with

452
Lars Gustäbel42e00912009-03-22 20:34:29 +0000453- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
454 forever on incomplete input. That caused tarfile.open() to hang when used
455 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
456 partial bzip2 compressed data.
457
Mark Dickinson79f52032009-03-17 23:12:51 +0000458- Issue #2110: Add support for thousands separator and 'n' type

Antoine Pitrou0ae29cf2009-03-13 22:33:17 +0000464- The error detection code in FileIO.close() could fail to reflect the `errno`
465 value, and report it as -1 instead.
466
Antoine Pitroua28fcfd2009-03-13 23:42:55 +0000467- Issue #5016: FileIO.seekable() could return False if the file position

Mark Dickinsonae681df2009-03-21 10:26:31 +0000475- Issue #5463: In struct module, remove deprecated overflow wrapping
476 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +0000477 struct.error instead of returning b'\xff\xff\xff\xff'. The
478 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
479 have been removed from the struct module.

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

541 type to (void *).
542
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000543- Issue #4935: The overflow checking code in the expandtabs() method common
544 to str, bytes and bytearray could be optimized away by the compiler, letting
545 the interpreter segfault instead of raising an error.
546
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000547- Issue #3720: Fix a crash when an iterator modifies its class and removes its

573 flag to work properly. Furthermore, when specifying -u, the text stdout
574 and stderr streams have line-by-line buffering enabled (the default being
575 to buffer arbitrary chunks of data).
576
Raymond Hettinger35631532009-01-09 03:58:09 +0000577- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
578 instead of ints (reducing its size from 4 to 8 times thereby reducing
579 Python's overall memory).
580
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000581- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
582 an existing .py counterpart, override the co_filename attributes of all
583 code objects if the original filename is obsolete (which can happen if the
584 file has been renamed, moved, or if it is accessed through different paths).
585 Patch by Ziga Seilnacht and Jean-Paul Calderone.
586
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000587- Issue #4580: Fix slicing of memoryviews when the item size is greater than
588 one byte. Also fixes the meaning of len() so that it returns the number of
589 items, rather than the size in bytes.
590
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000591- Issue #4075: Use OutputDebugStringW in Py_FatalError.
592
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000593- Issue #4747: When the terminal does not use utf-8, executing a script with
594 non-ascii characters in its name could fail with a "SyntaxError: None" error.

603 where the tp_hash and tp_dict slots are both NULL.
604
Georg Brandlccc47b62008-12-28 11:44:14 +0000605- Issue #4759: None is now allowed as the first argument of
606 bytearray.translate(). It was always allowed for bytes.translate().
607
Skip Montanaro80072cb2008-12-23 03:51:14 +0000608- Added test case to ensure attempts to read from a file opened for writing
609 fail.

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