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
Antoine Pitrou61f77b52009-05-24 15:46:13 +000035- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
36 than an int, which makes some operations possible under 64-bit Linux (e.g.
37 DN_MULTISHOT with F_NOTIFY).
38
Antoine Pitrou716c4442009-05-23 19:04:03 +000039- Issue #5761: Add the name of the underlying file to the repr() of various
40 IO objects.
41
R. David Murraycaa27b72009-05-23 18:49:56 +000042- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
43 by Musashi Tamura, tests by Marcin Bachry.
44
Antoine Pitrouc3ee1662009-05-23 16:02:33 +000045- Issue #1983: Fix functions taking or returning a process identifier to use
46 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
47 a process identifier type wider than the standard C integer type.
48
R. David Murray87e20742009-05-23 01:30:26 +000049- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
50 Patch by Farhan Ahmad, test by Marcin Bachry.
51
Antoine Pitrou6e610062009-05-15 17:04:50 +000052- Issue #2116: Weak references and weak dictionaries now support copy()ing and
53 deepcopy()ing.
54
Antoine Pitrouc1d09362009-05-15 12:15:51 +000055- Issue #1655: Make imaplib IPv6-capable. Patch by Derek Morr.
56
Antoine Pitrou37d1c182009-05-14 21:54:00 +000057- Issue #5918: Fix a crash in the parser module.
58
Antoine Pitrou2ca24f02009-05-14 21:30:46 +000059- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
60
Antoine Pitroue4501852009-05-14 18:55:55 +000061- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
62 library. This means, for example, that opening an UTF-16 text file in
63 append mode doesn't add a BOM at the end of the file if the file isn't
64 empty.
65
R. David Murray74b89242009-05-13 17:33:03 +000066- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
67 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
68 corrects a pydoc regression.
69
R. David Murray99352742009-05-07 18:24:38 +000070- Issue 5955: aifc's close method did not close the file it wrapped,
71 now it does. This also means getfp method now returns the real fp.
72
Benjamin Peterson932073a2009-05-23 16:14:33 +000073Installation
74------------
75
76- Issue #6047: fullinstall has been removed because Python 3's executable will
77 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +000078
Martin v. Löwisdb1c3992009-05-23 10:38:26 +000079Extension Modules

81
82- Issue #6093: Fix off-by-one error in locale.strxfrm.
83
Benjamin Peterson744af442009-05-23 18:51:49 +000084- The _functools and _locale modules are now built into the libpython shared
85 library instead of as extension modules.
Benjamin Peterson3dc22e82009-05-23 17:09:43 +000086
Brett Cannon1262e7c2009-05-11 01:47:11 +000087Tests
88-----
89
90- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
91 tests on darwin even when the OS was installed on a case-sensitive
92 filesystem. Also fixed tests that should not be run when
93 sys.dont_write_bytecode is true.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000100
101Core and Builtins
102-----------------
103
Mark Dickinson865e01a2009-05-07 16:37:01 +0000104- Issue #5914: Add new C API function PyOS_string_to_double, and
105 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
106
Eric Smith741191f2009-05-06 13:08:15 +0000107- Issue #3382: float.__format__, complex.__format__, and %-formatting
108 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
109 affects nan -> NAN and inf -> INF.
110
Mark Hammond5a607a32009-05-06 08:04:54 +0000111- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
112 in all operations, including splitdrive, split, etc. splitunc() now issues
113 a PendingDeprecation warning.
114
Eric Smith63376222009-05-05 14:04:18 +0000115- Issue #5920: For float.__format__, change the behavior with the
116 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
117 to be like 'g' but with at least one decimal point and with a
118 default precision of 12. Previously, the behavior the same but with
119 a default precision of 6. This more closely matches str(), and
120 reduces surprises when adding alignment flags to the empty
121 presentation type. This also affects the new complex.__format__ in
122 the same way.
123
Martin v. Löwis011e8422009-05-05 04:43:17 +0000124- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
125
R. David Murrayb18500d2009-05-04 22:59:07 +0000126- Issue #5890: in subclasses of 'property' the __doc__ attribute was
127 shadowed by classtype's, even if it was None. property now
128 inserts the __doc__ into the subclass instance __dict__.
129
Antoine Pitrou244651a2009-05-04 18:56:13 +0000130- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
131 sequences. Patch by Nick Barnes and Victor Stinner.
132
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000133- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000134
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000135- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
136 received a new method, detach(). detach() disconnects the underlying stream
137 from the buffer or text IO and returns it.
138
Mark Dickinson33841c32009-05-01 15:37:04 +0000139- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
140 floats with absolute value over 1e50. Also remove length
141 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
142 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000143
Eric Smith741191f2009-05-06 13:08:15 +0000144- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000145 format(complex(1, 2./3), '.5') now produces a sensible result.
146
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000147- Issue #5864: Fix empty format code formatting for floats so that it
148 never gives more than the requested number of significant digits.
149
Eric Smith6dc46f52009-04-27 20:39:49 +0000150- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
151 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
152
Eric Smithcc32a112009-04-26 21:35:14 +0000153- Issue #5835: Deprecate PyOS_ascii_formatd.
154
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000155- Issue #4971: Fix titlecase for characters that are their own
156 titlecase, but not their own uppercase.
157
Benjamin Peterson193152c2009-04-25 01:08:45 +0000158- Issue #5283: Setting __class__ in __del__ caused a segfault.
159
Mark Dickinsonad476da2009-04-23 19:14:16 +0000160- Issue #5816: complex(repr(z)) now recovers z exactly, even when
161 z involves nans, infs or negative zeros.
162
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000163- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000164
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000165- Issue #1869 (and many duplicates): make round(x, n) correctly
166 rounded for a float x, by using the decimal <-> binary conversions
167 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
168 consistently agrees with format(x, '.2f').
169
Benjamin Petersonae937c02009-04-18 20:54:08 +0000170- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
171 some builtin types.
172
Eric Smith0923d1d2009-04-16 20:16:10 +0000173- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
174
Eric Smith35e84722009-04-16 20:21:28 +0000175- Issue #5515: str.format() type 'n' combined with commas and leading
176 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000177
178- Implement PEP 378, Format Specifier for Thousands Separator, for
179 floats.
180
Mark Dickinson3370cce2009-04-17 22:40:53 +0000181- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000182 1e11, not 1e12. This avoids printing 13 significant digits in
183 situations where only 12 of them are correct. Example problem
184 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
185 long time.)
186
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000187- Issue #1580: On most platforms, use a 'short' float repr: for a
188 finite float x, repr(x) now outputs a string based on the shortest
189 sequence of decimal digits that rounds to x. Previous behaviour was
190 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000191 Another minor difference is that the new repr switches to
192 exponential notation at 1e16 instead of the previous 1e17; this
193 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000194
195 There's a new sys attribute sys.float_repr_style, which takes
196 the value 'short' to indicate that we're using short float repr,
197 and 'legacy' if the short float repr isn't available for one
198 reason or another.
199
200 The float repr change involves incorporating David Gay's 'perfect
201 rounding' code into the Python core (it's in Python/dtoa.c). As a
202 secondary consequence, all string-to-float and float-to-string
203 conversions (including all float formatting operations) will be
204 correctly rounded on these platforms.
205
206 See issue 1580 discussions for details of platforms for which
207 this change does not apply.
208
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000209- Issue #5759: float() didn't call __float__ on str subclasses.
210
Georg Brandlabc38772009-04-12 15:51:51 +0000211- The string.maketrans() function is deprecated; there is a new static method
212 maketrans() on the bytes and bytearray classes. This removes confusion about
213 the types string.maketrans() is supposed to work with, and mirrors the
214 methods available on the str class.
215
R. David Murraydc6da8a2009-04-09 22:16:43 +0000216- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
217 its clarity and its speed.
218
Matthias Klose091c7b12009-04-07 13:24:27 +0000219- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
220 to avoid compiler warnings.
221
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000222- Issue #3739: The unicode-internal encoder now reports the number of characters
223 consumed like any other encoder (instead of the number of bytes).
224
Benjamin Peterson0b4915e2009-04-25 21:11:45 +0000225Installation

325- Issue #5354: New test support function import_fresh_module() makes
326 it easy to import both normal and optimised versions of modules.
327 test_heapq and test_warnings have been adjusted to use it, tests for
328 other modules with both C and Python implementations in the stdlib
329 can be adjusted to use it over time.

Benjamin Peterson8f76b492009-04-03 22:22:42 +0000352- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
353
Benjamin Peterson7fe98532009-04-02 00:33:55 +0000354- Issue #5499: The 'c' code for argument parsing functions now only accepts a
355 byte, and the 'C' code only accepts a unicode character.
356
Georg Brandl406b3d82009-04-11 21:24:37 +0000357- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
358 when hitting the recursion limit under certain circumstances.
359
Brett Cannon0759dd62009-04-01 18:13:07 +0000360- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
361
Georg Brandlab6f2f62009-03-31 04:16:10 +0000362- Fix a segfault when running test_exceptions with coverage, caused by
363 insufficient checks in accessors of Exception.__context__.
364
Guido van Rossum0ad59d42009-03-30 22:01:35 +0000365- Issue #5604: non-ASCII characters in module name passed to
366 imp.find_module() were converted to UTF-8 while the path is
367 converted to the default filesystem encoding, causing nonsense.
368
Benjamin Peterson09832742009-03-26 17:15:46 +0000369- Issue #5126: str.isprintable() returned False for space characters.
370
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +0000371- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to

373
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000374- Issue #4688: Add a heuristic so that tuples and dicts containing only
375 untrackable objects are not tracked by the garbage collector. This can
376 reduce the size of collections and therefore the garbage collection overhead
377 on long-running programs, depending on their particular use of datatypes.
378
Mark Dickinson17e4fdd2009-03-23 18:44:57 +0000379- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

387 default. Add sys.int_info structseq to provide information about
388 the internal format.
389
Mark Dickinson081dfee2009-03-18 14:47:41 +0000390- Issue #4474: PyUnicode_FromWideChar now converts characters outside
391 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
392 and sizeof(Py_UNICODE) == 2.
393
Eric Smith8ec90442009-03-14 12:29:34 +0000394- Issue #5237: Allow auto-numbered fields in str.format(). For
395 example: '{} {}'.format(1, 2) == '1 2'.
396
Antoine Pitrou652e7072009-03-13 19:25:20 +0000397- Issue #5392: when a very low recursion limit was set, the interpreter would

410 error substitutions from non-strict codec error callbacks in
411 incrementalencoder and StreamWriter.
412
Georg Brandl33c28812009-04-01 23:07:29 +0000413- Issue #5656: Fix the coverage reporting when running the test suite with

446
Lars Gustäbel42e00912009-03-22 20:34:29 +0000447- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
448 forever on incomplete input. That caused tarfile.open() to hang when used
449 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
450 partial bzip2 compressed data.
451
Mark Dickinson79f52032009-03-17 23:12:51 +0000452- Issue #2110: Add support for thousands separator and 'n' type

Antoine Pitrou0ae29cf2009-03-13 22:33:17 +0000458- The error detection code in FileIO.close() could fail to reflect the `errno`
459 value, and report it as -1 instead.
460
Antoine Pitroua28fcfd2009-03-13 23:42:55 +0000461- Issue #5016: FileIO.seekable() could return False if the file position

Mark Dickinsonae681df2009-03-21 10:26:31 +0000469- Issue #5463: In struct module, remove deprecated overflow wrapping
470 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +0000471 struct.error instead of returning b'\xff\xff\xff\xff'. The
472 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
473 have been removed from the struct module.

Georg Brandl1cdd83c2009-04-05 20:24:29 +0000513- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +0000514 were suppressing all exceptions. These include list() and bytearray().

535 type to (void *).
536
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000537- Issue #4935: The overflow checking code in the expandtabs() method common
538 to str, bytes and bytearray could be optimized away by the compiler, letting
539 the interpreter segfault instead of raising an error.
540
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000541- Issue #3720: Fix a crash when an iterator modifies its class and removes its

567 flag to work properly. Furthermore, when specifying -u, the text stdout
568 and stderr streams have line-by-line buffering enabled (the default being
569 to buffer arbitrary chunks of data).
570
Raymond Hettinger35631532009-01-09 03:58:09 +0000571- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
572 instead of ints (reducing its size from 4 to 8 times thereby reducing
573 Python's overall memory).
574
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000575- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
576 an existing .py counterpart, override the co_filename attributes of all
577 code objects if the original filename is obsolete (which can happen if the
578 file has been renamed, moved, or if it is accessed through different paths).
579 Patch by Ziga Seilnacht and Jean-Paul Calderone.
580
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000581- Issue #4580: Fix slicing of memoryviews when the item size is greater than
582 one byte. Also fixes the meaning of len() so that it returns the number of
583 items, rather than the size in bytes.
584
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000585- Issue #4075: Use OutputDebugStringW in Py_FatalError.
586
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000587- Issue #4747: When the terminal does not use utf-8, executing a script with
588 non-ascii characters in its name could fail with a "SyntaxError: None" error.

597 where the tp_hash and tp_dict slots are both NULL.
598
Georg Brandlccc47b62008-12-28 11:44:14 +0000599- Issue #4759: None is now allowed as the first argument of
600 bytearray.translate(). It was always allowed for bytes.translate().
601
Skip Montanaro80072cb2008-12-23 03:51:14 +0000602- Added test case to ensure attempts to read from a file opened for writing
603 fail.

627 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
628 bytes instances. On a typical machine this saves 3 bytes of memory
629 (on average) per allocation of a bytes instance.

639 method on file objects with closefd=False. The file descriptor is still
640 kept open but the file object behaves like a closed file. The ``FileIO``
641 object also got a new readonly attribute ``closefd``.

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