133 using PyDescr_COMMON.
134
135- Issue #6405: Remove duplicate type declarations in descrobject.h.

232 to execute file paths that refer to source or compiled Python files as well
233 as zipfiles, directories and other valid sys.path entries that contain a
234 __main__.py file. This allows applications that run other Python scripts to
235 support the same flexibility as the CPython command line itself.

248 recursive locks as fast as regular non-recursive locks (previously,
249 they were slower by 10x to 15x).
250
Antoine Pitroub0872682009-11-09 16:08:16 +0000251- Issue #7282: Fix a memory leak when an RLock was used in a thread other

265 a modification is done through it. This fixes inconsistencies and test
266 failures on systems with slightly bogus mtime behaviour.
267
Gregory P. Smith50467882009-11-01 18:42:17 +0000268- Issue #7246 & Issue #7208: getpass now properly flushes input before
269 reading from stdin so that existing input does not confuse it and
270 lead to incorrect entry or an IOError. It also properly flushes it
271 afterwards to avoid the terminal echoing the input afterwards on
272 OSes such as Solaris.
273
Mark Dickinsona2d1fe02009-10-29 12:23:02 +0000274- Issue #7233: Fix a number of two-argument Decimal methods to make

702 (1) inf and nan strings with trailing whitespace were incorrectly
703 rejected; (2) parsing of strings representing infinities and nans
704 was locale aware; and (3) the interpretation of fromhex('-nan')
705 didn't match that of float('-nan').

721 names: cls, self, tuple, itemgetter, and property.
722
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000723- In unittest, using a skipping decorator on a class is now equivalent to
724 skipping every test on the class. The ClassTestSuite class has been removed.
725
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000726- Issue #6050: Don't fail extracting a directory from a zipfile if
727 the directory already exists.
728
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000729- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
730 than an int, which makes some operations possible under 64-bit Linux (e.g.
731 DN_MULTISHOT with F_NOTIFY).

740 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
741 a process identifier type wider than the standard C integer type.
742

754
Antoine Pitroue4501852009-05-14 18:55:55 +0000755- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
756 library. This means, for example, that opening an UTF-16 text file in
757 append mode doesn't add a BOM at the end of the file if the file isn't
758 empty.
759
R. David Murray74b89242009-05-13 17:33:03 +0000760- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
761 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
762 corrects a pydoc regression.
763
R. David Murray99352742009-05-07 18:24:38 +0000764- Issue 5955: aifc's close method did not close the file it wrapped,
765 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000807
808Core and Builtins
809-----------------
810
Mark Dickinson865e01a2009-05-07 16:37:01 +0000811- Issue #5914: Add new C API function PyOS_string_to_double, and
812 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
813
Eric Smith741191f2009-05-06 13:08:15 +0000814- Issue #3382: float.__format__, complex.__format__, and %-formatting
815 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
816 affects nan -> NAN and inf -> INF.
817
Mark Hammond5a607a32009-05-06 08:04:54 +0000818- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
819 in all operations, including splitdrive, split, etc. splitunc() now issues
820 a PendingDeprecation warning.
821
Eric Smith63376222009-05-05 14:04:18 +0000822- Issue #5920: For float.__format__, change the behavior with the
823 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
824 to be like 'g' but with at least one decimal point and with a
825 default precision of 12. Previously, the behavior the same but with
826 a default precision of 6. This more closely matches str(), and
827 reduces surprises when adding alignment flags to the empty
828 presentation type. This also affects the new complex.__format__ in
829 the same way.
830
Martin v. Löwis011e8422009-05-05 04:43:17 +0000831- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
832
R. David Murrayb18500d2009-05-04 22:59:07 +0000833- Issue #5890: in subclasses of 'property' the __doc__ attribute was
834 shadowed by classtype's, even if it was None. property now
835 inserts the __doc__ into the subclass instance __dict__.
836
Antoine Pitrou244651a2009-05-04 18:56:13 +0000837- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
838 sequences. Patch by Nick Barnes and Victor Stinner.
839
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000840- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000841
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000842- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
843 received a new method, detach(). detach() disconnects the underlying stream
844 from the buffer or text IO and returns it.
845
Mark Dickinson33841c32009-05-01 15:37:04 +0000846- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
847 floats with absolute value over 1e50. Also remove length
848 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
849 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000850
Eric Smith741191f2009-05-06 13:08:15 +0000851- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000852 format(complex(1, 2./3), '.5') now produces a sensible result.
853
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000854- Issue #5864: Fix empty format code formatting for floats so that it
855 never gives more than the requested number of significant digits.
856
Eric Smith6dc46f52009-04-27 20:39:49 +0000857- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
858 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
859
Eric Smithcc32a112009-04-26 21:35:14 +0000860- Issue #5835: Deprecate PyOS_ascii_formatd.
861
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000862- Issue #4971: Fix titlecase for characters that are their own
863 titlecase, but not their own uppercase.
864
Benjamin Peterson193152c2009-04-25 01:08:45 +0000865- Issue #5283: Setting __class__ in __del__ caused a segfault.
866
Mark Dickinsonad476da2009-04-23 19:14:16 +0000867- Issue #5816: complex(repr(z)) now recovers z exactly, even when
868 z involves nans, infs or negative zeros.
869
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000870- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000871
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000872- Issue #1869 (and many duplicates): make round(x, n) correctly
873 rounded for a float x, by using the decimal <-> binary conversions
874 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
875 consistently agrees with format(x, '.2f').
876
Benjamin Petersonae937c02009-04-18 20:54:08 +0000877- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
878 some builtin types.
879
Eric Smith0923d1d2009-04-16 20:16:10 +0000880- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
881
Eric Smith35e84722009-04-16 20:21:28 +0000882- Issue #5515: str.format() type 'n' combined with commas and leading
883 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000884
885- Implement PEP 378, Format Specifier for Thousands Separator, for
886 floats.
887
Mark Dickinson3370cce2009-04-17 22:40:53 +0000888- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000889 1e11, not 1e12. This avoids printing 13 significant digits in
890 situations where only 12 of them are correct. Example problem
891 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
892 long time.)
893
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000894- Issue #1580: On most platforms, use a 'short' float repr: for a
895 finite float x, repr(x) now outputs a string based on the shortest
896 sequence of decimal digits that rounds to x. Previous behaviour was
897 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000898 Another minor difference is that the new repr switches to
899 exponential notation at 1e16 instead of the previous 1e17; this
900 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000901
902 There's a new sys attribute sys.float_repr_style, which takes
903 the value 'short' to indicate that we're using short float repr,
904 and 'legacy' if the short float repr isn't available for one
905 reason or another.
906
907 The float repr change involves incorporating David Gay's 'perfect
908 rounding' code into the Python core (it's in Python/dtoa.c). As a
909 secondary consequence, all string-to-float and float-to-string

917
Georg Brandlabc38772009-04-12 15:51:51 +0000918- The string.maketrans() function is deprecated; there is a new static method

920 the types string.maketrans() is supposed to work with, and mirrors the
921 methods available on the str class.

1088 untrackable objects are not tracked by the garbage collector. This can
1089 reduce the size of collections and therefore the garbage collection overhead

Georg Brandl1cdd83c2009-04-05 20:24:29 +00001226- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001227 were suppressing all exceptions. These include list() and bytearray().
1228
Mark Dickinson1124e712009-01-28 21:25:58 +00001229- Issue #4707: round(x, n) now returns an integer if x is an integer.
1230 Previously it returned a float.
1231
Antoine Pitroub52ec782009-01-25 16:34:23 +00001232- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1233 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1234 evaluation loop is compiled with a new dispatch mechanism which gives
1235 speedups of up to 20%, depending on the system, on various benchmarks.
1236
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001237- Issue #4874: Most builtin decoders now reject unicode input.

1246
Mark Dickinson8055afd2009-01-17 10:04:45 +00001247- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1248 type to (void *).
1249
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001250- Issue #4935: The overflow checking code in the expandtabs() method common
1251 to str, bytes and bytearray could be optimized away by the compiler, letting
1252 the interpreter segfault instead of raising an error.
1253
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001254- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1255 __next__ method.
1256
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001257- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1258 function no longer attempt to call the __long__ slot to convert an object
1259 to an integer. Only the __int__ and __trunc__ slots are examined.

1264
Antoine Pitrouab868312009-01-10 15:40:25 +00001265- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1266 common cases are optimized thanks to a dedicated fast path and a moderate
1267 amount of loop unrolling.
1268
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001269- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1270 collecting the oldest generation) so that allocating lots of objects without
1271 destroying them does not show quadratic performance. Based on a proposal by
1272 Martin von Löwis at
1273 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1274
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001275- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001276 having been closed (for instance, a read() call could return some
1277 previously buffered data). Patch by Dmitry Vasiliev.
1278
Antoine Pitrou05608432009-01-09 18:53:14 +00001279- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1280 flag to work properly. Furthermore, when specifying -u, the text stdout
1281 and stderr streams have line-by-line buffering enabled (the default being
1282 to buffer arbitrary chunks of data).
1283
Raymond Hettinger35631532009-01-09 03:58:09 +00001284- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1285 instead of ints (reducing its size from 4 to 8 times thereby reducing
1286 Python's overall memory).
1287
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001288- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1289 an existing .py counterpart, override the co_filename attributes of all
1290 code objects if the original filename is obsolete (which can happen if the
1291 file has been renamed, moved, or if it is accessed through different paths).
1292 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1293
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001294- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1295 one byte. Also fixes the meaning of len() so that it returns the number of
1296 items, rather than the size in bytes.
1297
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001298- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1299
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001300- Issue #4747: When the terminal does not use utf-8, executing a script with
1301 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1302

1308
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001309- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1310 where the tp_hash and tp_dict slots are both NULL.
1311
Georg Brandlccc47b62008-12-28 11:44:14 +00001312- Issue #4759: None is now allowed as the first argument of
1313 bytearray.translate(). It was always allowed for bytes.translate().
1314
Skip Montanaro80072cb2008-12-23 03:51:14 +00001315- Added test case to ensure attempts to read from a file opened for writing
1316 fail.

1322
Antoine Pitrou621601a2008-12-17 23:18:19 +00001323- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

Mark Dickinsonda2706b2008-12-11 18:03:03 +00001329- Issue #2173: When getting device encoding, check that return value of
1330 nl_langinfo is not the empty string. This was causing silent build
1331 failures on OS X.
1332
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001333- Issue #4597: Fixed several opcodes that weren't always propagating
1334 exceptions.
1335
1336- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001337 context manager returns a value that cannot be converted to a bool.
1338
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001339- Issue #4445: Replace "sizeof(PyBytesObject)" with
1340 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1341 bytes instances. On a typical machine this saves 3 bytes of memory
1342 (on average) per allocation of a bytes instance.
1343
Christian Heimesa872de52008-12-05 08:26:55 +00001344- Issue #4533: File read operation was dreadfully slow due to a slowly
1345 growing read buffer. Fixed by using the same growth rate algorithm as
1346 Python 2.x.
1347
Antoine Pitrou5504e892008-12-06 21:27:53 +00001348- Issue #4509: Various issues surrounding resize of bytearray objects to
1349 which there are buffer exports (e.g. memoryview instances).
1350
Georg Brandlf9734072008-12-07 15:30:06 +00001351- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1352 method on file objects with closefd=False. The file descriptor is still
1353 kept open but the file object behaves like a closed file. The ``FileIO``
1354 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00001363- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1364 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1365 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1366 of using the replace error handler in PyUnicode_DecodeUTF8().
