128 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
129 should used for accessing the d_type and d_name members of structures
130 using PyDescr_COMMON.
131
132- Issue #6405: Remove duplicate type declarations in descrobject.h.
Benjamin Peterson89b89172009-07-03 13:30:25 +0000133

Tarek Ziadéacafc2d2009-11-29 22:24:57 +0000158- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
159 ownership when the group is not forced, because the group may be different

207 to execute file paths that refer to source or compiled Python files as well
208 as zipfiles, directories and other valid sys.path entries that contain a
209 __main__.py file. This allows applications that run other Python scripts to
210 support the same flexibility as the CPython command line itself.
211
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000212- Issue #7318: multiprocessing now uses a timeout when it fails to establish

222 default when instantiating a `threading.RLock` object. This makes
223 recursive locks as fast as regular non-recursive locks (previously,
224 they were slower by 10x to 15x).
225
Antoine Pitroub0872682009-11-09 16:08:16 +0000226- Issue #7282: Fix a memory leak when an RLock was used in a thread other

240 a modification is done through it. This fixes inconsistencies and test
241 failures on systems with slightly bogus mtime behaviour.
242
Gregory P. Smith50467882009-11-01 18:42:17 +0000243- Issue #7246 & Issue #7208: getpass now properly flushes input before
244 reading from stdin so that existing input does not confuse it and
245 lead to incorrect entry or an IOError. It also properly flushes it
246 afterwards to avoid the terminal echoing the input afterwards on
247 OSes such as Solaris.
248
Mark Dickinsona2d1fe02009-10-29 12:23:02 +0000249- Issue #7233: Fix a number of two-argument Decimal methods to make

251 fix buggy handling of large arguments (those with coefficient longer
252 than the current precision) in shift and rotate.

480 the road because the internally cached encoders and decoders would point
481 to empty global variables.
482

656 that would raise SystemError.
657
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000658- Issue #5982: staticmethod and classmethod now expose the wrapped
659 function with __func__.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000664- Issue #5829: complex("1e500") no longer raises OverflowError. This
665 makes it consistent with float("1e500") and interpretation of real
666 and imaginary literals.
667
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000668- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

671
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000672- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
673 (1) inf and nan strings with trailing whitespace were incorrectly
674 rejected; (2) parsing of strings representing infinities and nans
675 was locale aware; and (3) the interpretation of fromhex('-nan')
676 didn't match that of float('-nan').

692 names: cls, self, tuple, itemgetter, and property.
693
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000694- In unittest, using a skipping decorator on a class is now equivalent to
695 skipping every test on the class. The ClassTestSuite class has been removed.
696
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000697- Issue #6050: Don't fail extracting a directory from a zipfile if
698 the directory already exists.
699
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000700- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
701 than an int, which makes some operations possible under 64-bit Linux (e.g.
702 DN_MULTISHOT with F_NOTIFY).

709
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000710- Issue #1983: Fix functions taking or returning a process identifier to use
711 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
712 a process identifier type wider than the standard C integer type.
713
R. David Murray87e20742009-05-23 01:30:26 +0000714- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

725
Antoine Pitroue4501852009-05-14 18:55:55 +0000726- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
727 library. This means, for example, that opening an UTF-16 text file in
728 append mode doesn't add a BOM at the end of the file if the file isn't
729 empty.
730
R. David Murray74b89242009-05-13 17:33:03 +0000731- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
732 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
733 corrects a pydoc regression.
734
R. David Murray99352742009-05-07 18:24:38 +0000735- Issue 5955: aifc's close method did not close the file it wrapped,
736 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000778
779Core and Builtins
780-----------------
781
Mark Dickinson865e01a2009-05-07 16:37:01 +0000782- Issue #5914: Add new C API function PyOS_string_to_double, and
783 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
784
Eric Smith741191f2009-05-06 13:08:15 +0000785- Issue #3382: float.__format__, complex.__format__, and %-formatting
786 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
787 affects nan -> NAN and inf -> INF.
788
Mark Hammond5a607a32009-05-06 08:04:54 +0000789- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
790 in all operations, including splitdrive, split, etc. splitunc() now issues
791 a PendingDeprecation warning.
792
Eric Smith63376222009-05-05 14:04:18 +0000793- Issue #5920: For float.__format__, change the behavior with the
794 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
795 to be like 'g' but with at least one decimal point and with a
796 default precision of 12. Previously, the behavior the same but with
797 a default precision of 6. This more closely matches str(), and
798 reduces surprises when adding alignment flags to the empty
799 presentation type. This also affects the new complex.__format__ in
800 the same way.
801
Martin v. Löwis011e8422009-05-05 04:43:17 +0000802- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
803
R. David Murrayb18500d2009-05-04 22:59:07 +0000804- Issue #5890: in subclasses of 'property' the __doc__ attribute was
805 shadowed by classtype's, even if it was None. property now
806 inserts the __doc__ into the subclass instance __dict__.
807
Antoine Pitrou244651a2009-05-04 18:56:13 +0000808- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
809 sequences. Patch by Nick Barnes and Victor Stinner.
810
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000811- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000812
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000813- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
814 received a new method, detach(). detach() disconnects the underlying stream
815 from the buffer or text IO and returns it.
816
Mark Dickinson33841c32009-05-01 15:37:04 +0000817- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
818 floats with absolute value over 1e50. Also remove length
819 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
820 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000821
Eric Smith741191f2009-05-06 13:08:15 +0000822- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000823 format(complex(1, 2./3), '.5') now produces a sensible result.
824
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000825- Issue #5864: Fix empty format code formatting for floats so that it
826 never gives more than the requested number of significant digits.
827
Eric Smith6dc46f52009-04-27 20:39:49 +0000828- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
829 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
830
Eric Smithcc32a112009-04-26 21:35:14 +0000831- Issue #5835: Deprecate PyOS_ascii_formatd.
832
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000833- Issue #4971: Fix titlecase for characters that are their own
834 titlecase, but not their own uppercase.
835
Benjamin Peterson193152c2009-04-25 01:08:45 +0000836- Issue #5283: Setting __class__ in __del__ caused a segfault.
837
Mark Dickinsonad476da2009-04-23 19:14:16 +0000838- Issue #5816: complex(repr(z)) now recovers z exactly, even when
839 z involves nans, infs or negative zeros.
840
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000841- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000842
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000843- Issue #1869 (and many duplicates): make round(x, n) correctly
844 rounded for a float x, by using the decimal <-> binary conversions
845 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
846 consistently agrees with format(x, '.2f').
847
Benjamin Petersonae937c02009-04-18 20:54:08 +0000848- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
849 some builtin types.
850
Eric Smith0923d1d2009-04-16 20:16:10 +0000851- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
852
Eric Smith35e84722009-04-16 20:21:28 +0000853- Issue #5515: str.format() type 'n' combined with commas and leading
854 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000855
856- Implement PEP 378, Format Specifier for Thousands Separator, for
857 floats.
858
Mark Dickinson3370cce2009-04-17 22:40:53 +0000859- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000860 1e11, not 1e12. This avoids printing 13 significant digits in
861 situations where only 12 of them are correct. Example problem
862 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
863 long time.)
864
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000865- Issue #1580: On most platforms, use a 'short' float repr: for a
866 finite float x, repr(x) now outputs a string based on the shortest
867 sequence of decimal digits that rounds to x. Previous behaviour was
868 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000869 Another minor difference is that the new repr switches to
870 exponential notation at 1e16 instead of the previous 1e17; this
871 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000872
873 There's a new sys attribute sys.float_repr_style, which takes
874 the value 'short' to indicate that we're using short float repr,
875 and 'legacy' if the short float repr isn't available for one
876 reason or another.
877
878 The float repr change involves incorporating David Gay's 'perfect
879 rounding' code into the Python core (it's in Python/dtoa.c). As a
880 secondary consequence, all string-to-float and float-to-string
881 conversions (including all float formatting operations) will be
882 correctly rounded on these platforms.
883
884 See issue 1580 discussions for details of platforms for which
885 this change does not apply.
886
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000887- Issue #5759: float() didn't call __float__ on str subclasses.
888
Georg Brandlabc38772009-04-12 15:51:51 +0000889- The string.maketrans() function is deprecated; there is a new static method
890 maketrans() on the bytes and bytearray classes. This removes confusion about
891 the types string.maketrans() is supposed to work with, and mirrors the
892 methods available on the str class.
893
R. David Murraydc6da8a2009-04-09 22:16:43 +0000894- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
895 its clarity and its speed.
896
Matthias Klose091c7b12009-04-07 13:24:27 +0000897- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
898 to avoid compiler warnings.
899
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000900- Issue #3739: The unicode-internal encoder now reports the number of characters
901 consumed like any other encoder (instead of the number of bytes).

912 specific Python version.
913
Raymond Hettingereb816952009-05-29 01:22:18 +0000914- Issue #5150: IDLE's format menu now has an option to strip trailing

916
Vinay Sajipaffbd872009-06-11 10:11:47 +0000917- Issue #5940: distutils.command.build_clib.check_library_list was not doing

Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001215- Issue #4838: When a module is deallocated, free the memory backing the
1216 optional module state data.
1217
Mark Dickinson8055afd2009-01-17 10:04:45 +00001218- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1219 type to (void *).
1220
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001221- Issue #4935: The overflow checking code in the expandtabs() method common
1222 to str, bytes and bytearray could be optimized away by the compiler, letting
1223 the interpreter segfault instead of raising an error.
1224
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001225- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1226 __next__ method.
1227
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001228- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1229 function no longer attempt to call the __long__ slot to convert an object
1230 to an integer. Only the __int__ and __trunc__ slots are examined.

1235
Antoine Pitrouab868312009-01-10 15:40:25 +00001236- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1237 common cases are optimized thanks to a dedicated fast path and a moderate
1238 amount of loop unrolling.
1239
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001240- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1241 collecting the oldest generation) so that allocating lots of objects without
1242 destroying them does not show quadratic performance. Based on a proposal by
1243 Martin von Löwis at
1244 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1245
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001246- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001247 having been closed (for instance, a read() call could return some
1248 previously buffered data). Patch by Dmitry Vasiliev.
1249
Antoine Pitrou05608432009-01-09 18:53:14 +00001250- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1251 flag to work properly. Furthermore, when specifying -u, the text stdout
1252 and stderr streams have line-by-line buffering enabled (the default being
1253 to buffer arbitrary chunks of data).
1254
Raymond Hettinger35631532009-01-09 03:58:09 +00001255- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1256 instead of ints (reducing its size from 4 to 8 times thereby reducing
1257 Python's overall memory).
1258
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001259- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1260 an existing .py counterpart, override the co_filename attributes of all
1261 code objects if the original filename is obsolete (which can happen if the
1262 file has been renamed, moved, or if it is accessed through different paths).
1263 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1264
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001265- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1266 one byte. Also fixes the meaning of len() so that it returns the number of
1267 items, rather than the size in bytes.
1268
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001269- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1270
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001271- Issue #4747: When the terminal does not use utf-8, executing a script with
1272 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1273

1278 did not get collected.
1279
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001280- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1281 where the tp_hash and tp_dict slots are both NULL.
1282
Georg Brandlccc47b62008-12-28 11:44:14 +00001283- Issue #4759: None is now allowed as the first argument of
1284 bytearray.translate(). It was always allowed for bytes.translate().
1285
Skip Montanaro80072cb2008-12-23 03:51:14 +00001286- Added test case to ensure attempts to read from a file opened for writing
1287 fail.
1288
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001289- Issue #3106: Speedup some comparisons (str/str and int/int).

1293
Antoine Pitrou621601a2008-12-17 23:18:19 +00001294- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1296 unreachable. Original patch by Neil Schemenauer.
1297

1299
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001300- Issue #2173: When getting device encoding, check that return value of
1301 nl_langinfo is not the empty string. This was causing silent build
1302 failures on OS X.
1303
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001304- Issue #4597: Fixed several opcodes that weren't always propagating
1305 exceptions.
1306
1307- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001308 context manager returns a value that cannot be converted to a bool.
1309
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001310- Issue #4445: Replace "sizeof(PyBytesObject)" with
1311 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1312 bytes instances. On a typical machine this saves 3 bytes of memory
1313 (on average) per allocation of a bytes instance.
1314
Christian Heimesa872de52008-12-05 08:26:55 +00001315- Issue #4533: File read operation was dreadfully slow due to a slowly
1316 growing read buffer. Fixed by using the same growth rate algorithm as
1317 Python 2.x.
1318
Antoine Pitrou5504e892008-12-06 21:27:53 +00001319- Issue #4509: Various issues surrounding resize of bytearray objects to
1320 which there are buffer exports (e.g. memoryview instances).
1321
Georg Brandlf9734072008-12-07 15:30:06 +00001322- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1323 method on file objects with closefd=False. The file descriptor is still
1324 kept open but the file object behaves like a closed file. The ``FileIO``
1325 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00001327- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1333
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001334- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1335 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1336 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1337 of using the replace error handler in PyUnicode_DecodeUTF8().
