131 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
132 should used for accessing the d_type and d_name members of structures
133 using PyDescr_COMMON.
134
135- Issue #6405: Remove duplicate type declarations in descrobject.h.

210 to execute file paths that refer to source or compiled Python files as well
211 as zipfiles, directories and other valid sys.path entries that contain a
212 __main__.py file. This allows applications that run other Python scripts to
213 support the same flexibility as the CPython command line itself.
214
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000215- Issue #7318: multiprocessing now uses a timeout when it fails to establish

225 default when instantiating a `threading.RLock` object. This makes
226 recursive locks as fast as regular non-recursive locks (previously,
227 they were slower by 10x to 15x).
228
Antoine Pitroub0872682009-11-09 16:08:16 +0000229- Issue #7282: Fix a memory leak when an RLock was used in a thread other

Antoine Pitrou03f13442009-11-02 11:36:51 +0000242- Issue #6896: mailbox.Maildir now invalidates its internal cache each time
243 a modification is done through it. This fixes inconsistencies and test
244 failures on systems with slightly bogus mtime behaviour.
245
Gregory P. Smith50467882009-11-01 18:42:17 +0000246- Issue #7246 & Issue #7208: getpass now properly flushes input before
247 reading from stdin so that existing input does not confuse it and
248 lead to incorrect entry or an IOError. It also properly flushes it
249 afterwards to avoid the terminal echoing the input afterwards on
250 OSes such as Solaris.
251
Mark Dickinsona2d1fe02009-10-29 12:23:02 +0000252- Issue #7233: Fix a number of two-argument Decimal methods to make

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

483 the road because the internally cached encoders and decoders would point
484 to empty global variables.

659 that would raise SystemError.
660
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000661- Issue #5982: staticmethod and classmethod now expose the wrapped
662 function with __func__.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000667- Issue #5829: complex("1e500") no longer raises OverflowError. This
668 makes it consistent with float("1e500") and interpretation of real
669 and imaginary literals.
670
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000671- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

674
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000675- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
676 (1) inf and nan strings with trailing whitespace were incorrectly
677 rejected; (2) parsing of strings representing infinities and nans
678 was locale aware; and (3) the interpretation of fromhex('-nan')
679 didn't match that of float('-nan').

692 arguments for strings with a space in them.
693
Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000694- collections.namedtuple() was not working with the following field
695 names: cls, self, tuple, itemgetter, and property.
696
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000697- In unittest, using a skipping decorator on a class is now equivalent to
698 skipping every test on the class. The ClassTestSuite class has been removed.
699
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000700- Issue #6050: Don't fail extracting a directory from a zipfile if
701 the directory already exists.
702
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000703- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
704 than an int, which makes some operations possible under 64-bit Linux (e.g.
705 DN_MULTISHOT with F_NOTIFY).
706
Antoine Pitrou716c4442009-05-23 19:04:03 +0000707- Issue #5761: Add the name of the underlying file to the repr() of various

711 by Musashi Tamura, tests by Marcin Bachry.
712
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000713- Issue #1983: Fix functions taking or returning a process identifier to use
714 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
715 a process identifier type wider than the standard C integer type.
716
R. David Murray87e20742009-05-23 01:30:26 +0000717- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

728
Antoine Pitroue4501852009-05-14 18:55:55 +0000729- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
730 library. This means, for example, that opening an UTF-16 text file in
731 append mode doesn't add a BOM at the end of the file if the file isn't
732 empty.
733
R. David Murray74b89242009-05-13 17:33:03 +0000734- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
735 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
736 corrects a pydoc regression.
737
R. David Murray99352742009-05-07 18:24:38 +0000738- Issue 5955: aifc's close method did not close the file it wrapped,
739 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000781
782Core and Builtins
783-----------------
784
Mark Dickinson865e01a2009-05-07 16:37:01 +0000785- Issue #5914: Add new C API function PyOS_string_to_double, and
786 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
787
Eric Smith741191f2009-05-06 13:08:15 +0000788- Issue #3382: float.__format__, complex.__format__, and %-formatting
789 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
790 affects nan -> NAN and inf -> INF.
791
Mark Hammond5a607a32009-05-06 08:04:54 +0000792- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
793 in all operations, including splitdrive, split, etc. splitunc() now issues
794 a PendingDeprecation warning.
795
Eric Smith63376222009-05-05 14:04:18 +0000796- Issue #5920: For float.__format__, change the behavior with the
797 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
798 to be like 'g' but with at least one decimal point and with a
799 default precision of 12. Previously, the behavior the same but with
800 a default precision of 6. This more closely matches str(), and
801 reduces surprises when adding alignment flags to the empty
802 presentation type. This also affects the new complex.__format__ in
803 the same way.
804
Martin v. Löwis011e8422009-05-05 04:43:17 +0000805- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
806
R. David Murrayb18500d2009-05-04 22:59:07 +0000807- Issue #5890: in subclasses of 'property' the __doc__ attribute was
808 shadowed by classtype's, even if it was None. property now
809 inserts the __doc__ into the subclass instance __dict__.
810
Antoine Pitrou244651a2009-05-04 18:56:13 +0000811- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
812 sequences. Patch by Nick Barnes and Victor Stinner.
813
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000814- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000815
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000816- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
817 received a new method, detach(). detach() disconnects the underlying stream
818 from the buffer or text IO and returns it.
819
Mark Dickinson33841c32009-05-01 15:37:04 +0000820- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
821 floats with absolute value over 1e50. Also remove length
822 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
823 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000824
Eric Smith741191f2009-05-06 13:08:15 +0000825- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000826 format(complex(1, 2./3), '.5') now produces a sensible result.
827
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000828- Issue #5864: Fix empty format code formatting for floats so that it
829 never gives more than the requested number of significant digits.
830
Eric Smith6dc46f52009-04-27 20:39:49 +0000831- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
832 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
833
Eric Smithcc32a112009-04-26 21:35:14 +0000834- Issue #5835: Deprecate PyOS_ascii_formatd.
835
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000836- Issue #4971: Fix titlecase for characters that are their own
837 titlecase, but not their own uppercase.
838
Benjamin Peterson193152c2009-04-25 01:08:45 +0000839- Issue #5283: Setting __class__ in __del__ caused a segfault.
840
Mark Dickinsonad476da2009-04-23 19:14:16 +0000841- Issue #5816: complex(repr(z)) now recovers z exactly, even when
842 z involves nans, infs or negative zeros.
843
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000844- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000845
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000846- Issue #1869 (and many duplicates): make round(x, n) correctly
847 rounded for a float x, by using the decimal <-> binary conversions
848 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
849 consistently agrees with format(x, '.2f').
850
Benjamin Petersonae937c02009-04-18 20:54:08 +0000851- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
852 some builtin types.
853
Eric Smith0923d1d2009-04-16 20:16:10 +0000854- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
855
Eric Smith35e84722009-04-16 20:21:28 +0000856- Issue #5515: str.format() type 'n' combined with commas and leading
857 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000858
859- Implement PEP 378, Format Specifier for Thousands Separator, for
860 floats.
861
Mark Dickinson3370cce2009-04-17 22:40:53 +0000862- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000863 1e11, not 1e12. This avoids printing 13 significant digits in
864 situations where only 12 of them are correct. Example problem
865 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
866 long time.)
867
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000868- Issue #1580: On most platforms, use a 'short' float repr: for a
869 finite float x, repr(x) now outputs a string based on the shortest
870 sequence of decimal digits that rounds to x. Previous behaviour was
871 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000872 Another minor difference is that the new repr switches to
873 exponential notation at 1e16 instead of the previous 1e17; this
874 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000875
876 There's a new sys attribute sys.float_repr_style, which takes
877 the value 'short' to indicate that we're using short float repr,
878 and 'legacy' if the short float repr isn't available for one
879 reason or another.
880
881 The float repr change involves incorporating David Gay's 'perfect
882 rounding' code into the Python core (it's in Python/dtoa.c). As a
883 secondary consequence, all string-to-float and float-to-string
884 conversions (including all float formatting operations) will be
885 correctly rounded on these platforms.
886
887 See issue 1580 discussions for details of platforms for which
888 this change does not apply.
889
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000890- Issue #5759: float() didn't call __float__ on str subclasses.
891
Georg Brandlabc38772009-04-12 15:51:51 +0000892- The string.maketrans() function is deprecated; there is a new static method
893 maketrans() on the bytes and bytearray classes. This removes confusion about
894 the types string.maketrans() is supposed to work with, and mirrors the
895 methods available on the str class.
896
R. David Murraydc6da8a2009-04-09 22:16:43 +0000897- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
898 its clarity and its speed.
899
Matthias Klose091c7b12009-04-07 13:24:27 +0000900- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
901 to avoid compiler warnings.
902
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000903- Issue #3739: The unicode-internal encoder now reports the number of characters
904 consumed like any other encoder (instead of the number of bytes).

915 specific Python version.
916
Raymond Hettingereb816952009-05-29 01:22:18 +0000917- Issue #5150: IDLE's format menu now has an option to strip trailing

Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001218- Issue #4838: When a module is deallocated, free the memory backing the
1219 optional module state data.
1220
Mark Dickinson8055afd2009-01-17 10:04:45 +00001221- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1222 type to (void *).
1223
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001224- Issue #4935: The overflow checking code in the expandtabs() method common
1225 to str, bytes and bytearray could be optimized away by the compiler, letting
1226 the interpreter segfault instead of raising an error.
1227
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001228- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1229 __next__ method.
1230
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001231- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1232 function no longer attempt to call the __long__ slot to convert an object
1233 to an integer. Only the __int__ and __trunc__ slots are examined.

1238
Antoine Pitrouab868312009-01-10 15:40:25 +00001239- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1240 common cases are optimized thanks to a dedicated fast path and a moderate
1241 amount of loop unrolling.
1242
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001243- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1244 collecting the oldest generation) so that allocating lots of objects without
1245 destroying them does not show quadratic performance. Based on a proposal by
1246 Martin von Löwis at
1247 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1248
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001249- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001250 having been closed (for instance, a read() call could return some
1251 previously buffered data). Patch by Dmitry Vasiliev.
1252
Antoine Pitrou05608432009-01-09 18:53:14 +00001253- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1254 flag to work properly. Furthermore, when specifying -u, the text stdout
1255 and stderr streams have line-by-line buffering enabled (the default being
1256 to buffer arbitrary chunks of data).
1257
Raymond Hettinger35631532009-01-09 03:58:09 +00001258- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1259 instead of ints (reducing its size from 4 to 8 times thereby reducing
1260 Python's overall memory).
1261
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001262- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1263 an existing .py counterpart, override the co_filename attributes of all
1264 code objects if the original filename is obsolete (which can happen if the
1265 file has been renamed, moved, or if it is accessed through different paths).
1266 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1267
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001268- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1269 one byte. Also fixes the meaning of len() so that it returns the number of
1270 items, rather than the size in bytes.
1271
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001272- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1273
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001274- Issue #4747: When the terminal does not use utf-8, executing a script with
1275 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1276
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001277- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

1281 did not get collected.
1282
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001283- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1284 where the tp_hash and tp_dict slots are both NULL.
1285
Georg Brandlccc47b62008-12-28 11:44:14 +00001286- Issue #4759: None is now allowed as the first argument of
1287 bytearray.translate(). It was always allowed for bytes.translate().
1288
Skip Montanaro80072cb2008-12-23 03:51:14 +00001289- Added test case to ensure attempts to read from a file opened for writing
1290 fail.

1296
Antoine Pitrou621601a2008-12-17 23:18:19 +00001297- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1299 unreachable. Original patch by Neil Schemenauer.
1300

1302
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001303- Issue #2173: When getting device encoding, check that return value of
1304 nl_langinfo is not the empty string. This was causing silent build
1305 failures on OS X.
1306
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001307- Issue #4597: Fixed several opcodes that weren't always propagating
1308 exceptions.
1309
1310- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001311 context manager returns a value that cannot be converted to a bool.
1312
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001313- Issue #4445: Replace "sizeof(PyBytesObject)" with
1314 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1315 bytes instances. On a typical machine this saves 3 bytes of memory
1316 (on average) per allocation of a bytes instance.
1317
Christian Heimesa872de52008-12-05 08:26:55 +00001318- Issue #4533: File read operation was dreadfully slow due to a slowly
1319 growing read buffer. Fixed by using the same growth rate algorithm as
1320 Python 2.x.
1321
Antoine Pitrou5504e892008-12-06 21:27:53 +00001322- Issue #4509: Various issues surrounding resize of bytearray objects to
1323 which there are buffer exports (e.g. memoryview instances).
1324
Georg Brandlf9734072008-12-07 15:30:06 +00001325- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1326 method on file objects with closefd=False. The file descriptor is still
1327 kept open but the file object behaves like a closed file. The ``FileIO``
1328 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00001330- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1336
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001337- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1338 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1339 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1340 of using the replace error handler in PyUnicode_DecodeUTF8().
