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

262 recursive locks as fast as regular non-recursive locks (previously,
263 they were slower by 10x to 15x).
264
Antoine Pitroub0872682009-11-09 16:08:16 +0000265- Issue #7282: Fix a memory leak when an RLock was used in a thread other
266 than those started through `threading.Thread` (for example, using

Gregory P. Smith50467882009-11-01 18:42:17 +0000282- Issue #7246 & Issue #7208: getpass now properly flushes input before
283 reading from stdin so that existing input does not confuse it and
284 lead to incorrect entry or an IOError. It also properly flushes it
285 afterwards to avoid the terminal echoing the input afterwards on
286 OSes such as Solaris.

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

739
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000740- Issue #6050: Don't fail extracting a directory from a zipfile if
741 the directory already exists.
742
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000743- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
744 than an int, which makes some operations possible under 64-bit Linux (e.g.

Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000753- Issue #1983: Fix functions taking or returning a process identifier to use
754 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
755 a process identifier type wider than the standard C integer type.

768
Antoine Pitroue4501852009-05-14 18:55:55 +0000769- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
770 library. This means, for example, that opening an UTF-16 text file in
771 append mode doesn't add a BOM at the end of the file if the file isn't
772 empty.
773
R. David Murray74b89242009-05-13 17:33:03 +0000774- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
775 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
776 corrects a pydoc regression.
777
R. David Murray99352742009-05-07 18:24:38 +0000778- Issue 5955: aifc's close method did not close the file it wrapped,
779 now it does. This also means getfp method now returns the real fp.

822Core and Builtins
823-----------------
824
Mark Dickinson865e01a2009-05-07 16:37:01 +0000825- Issue #5914: Add new C API function PyOS_string_to_double, and
826 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
827
Eric Smith741191f2009-05-06 13:08:15 +0000828- Issue #3382: float.__format__, complex.__format__, and %-formatting
829 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
830 affects nan -> NAN and inf -> INF.
831
Mark Hammond5a607a32009-05-06 08:04:54 +0000832- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
833 in all operations, including splitdrive, split, etc. splitunc() now issues
834 a PendingDeprecation warning.
835
Eric Smith63376222009-05-05 14:04:18 +0000836- Issue #5920: For float.__format__, change the behavior with the
837 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
838 to be like 'g' but with at least one decimal point and with a
839 default precision of 12. Previously, the behavior the same but with
840 a default precision of 6. This more closely matches str(), and
841 reduces surprises when adding alignment flags to the empty
842 presentation type. This also affects the new complex.__format__ in
843 the same way.
844
Martin v. Löwis011e8422009-05-05 04:43:17 +0000845- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
846
R. David Murrayb18500d2009-05-04 22:59:07 +0000847- Issue #5890: in subclasses of 'property' the __doc__ attribute was
848 shadowed by classtype's, even if it was None. property now
849 inserts the __doc__ into the subclass instance __dict__.
850
Antoine Pitrou244651a2009-05-04 18:56:13 +0000851- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
852 sequences. Patch by Nick Barnes and Victor Stinner.
853
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000854- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000855
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000856- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
857 received a new method, detach(). detach() disconnects the underlying stream
858 from the buffer or text IO and returns it.
859
Mark Dickinson33841c32009-05-01 15:37:04 +0000860- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
861 floats with absolute value over 1e50. Also remove length
862 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
863 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000864
Eric Smith741191f2009-05-06 13:08:15 +0000865- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000866 format(complex(1, 2./3), '.5') now produces a sensible result.
867
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000868- Issue #5864: Fix empty format code formatting for floats so that it
869 never gives more than the requested number of significant digits.
870
Eric Smith6dc46f52009-04-27 20:39:49 +0000871- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
872 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
873
Eric Smithcc32a112009-04-26 21:35:14 +0000874- Issue #5835: Deprecate PyOS_ascii_formatd.
875
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000876- Issue #4971: Fix titlecase for characters that are their own
877 titlecase, but not their own uppercase.
878
Benjamin Peterson193152c2009-04-25 01:08:45 +0000879- Issue #5283: Setting __class__ in __del__ caused a segfault.
880
Mark Dickinsonad476da2009-04-23 19:14:16 +0000881- Issue #5816: complex(repr(z)) now recovers z exactly, even when
882 z involves nans, infs or negative zeros.
883
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000884- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000885
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000886- Issue #1869 (and many duplicates): make round(x, n) correctly
887 rounded for a float x, by using the decimal <-> binary conversions
888 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
889 consistently agrees with format(x, '.2f').
890
Benjamin Petersonae937c02009-04-18 20:54:08 +0000891- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
892 some builtin types.
893
Eric Smith0923d1d2009-04-16 20:16:10 +0000894- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
895
Eric Smith35e84722009-04-16 20:21:28 +0000896- Issue #5515: str.format() type 'n' combined with commas and leading
897 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000898
899- Implement PEP 378, Format Specifier for Thousands Separator, for
900 floats.
901
Mark Dickinson3370cce2009-04-17 22:40:53 +0000902- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000903 1e11, not 1e12. This avoids printing 13 significant digits in
904 situations where only 12 of them are correct. Example problem
905 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
906 long time.)
907
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000908- Issue #1580: On most platforms, use a 'short' float repr: for a
909 finite float x, repr(x) now outputs a string based on the shortest
910 sequence of decimal digits that rounds to x. Previous behaviour was
911 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000912 Another minor difference is that the new repr switches to
913 exponential notation at 1e16 instead of the previous 1e17; this
914 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000915
916 There's a new sys attribute sys.float_repr_style, which takes
917 the value 'short' to indicate that we're using short float repr,
918 and 'legacy' if the short float repr isn't available for one
919 reason or another.
920
921 The float repr change involves incorporating David Gay's 'perfect
922 rounding' code into the Python core (it's in Python/dtoa.c). As a
923 secondary consequence, all string-to-float and float-to-string
924 conversions (including all float formatting operations) will be
925 correctly rounded on these platforms.
926
927 See issue 1580 discussions for details of platforms for which
928 this change does not apply.

931
Georg Brandlabc38772009-04-12 15:51:51 +0000932- The string.maketrans() function is deprecated; there is a new static method
933 maketrans() on the bytes and bytearray classes. This removes confusion about
934 the types string.maketrans() is supposed to work with, and mirrors the
935 methods available on the str class.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00001240- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001241 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00001243- Issue #4707: round(x, n) now returns an integer if x is an integer.
1244 Previously it returned a float.
1245
Antoine Pitroub52ec782009-01-25 16:34:23 +00001246- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1247 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1248 evaluation loop is compiled with a new dispatch mechanism which gives
1249 speedups of up to 20%, depending on the system, on various benchmarks.

Mark Dickinson8055afd2009-01-17 10:04:45 +00001261- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1262 type to (void *).
1263
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001264- Issue #4935: The overflow checking code in the expandtabs() method common
1265 to str, bytes and bytearray could be optimized away by the compiler, letting
1266 the interpreter segfault instead of raising an error.
1267
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001268- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1269 __next__ method.
1270
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001271- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

1278
Antoine Pitrouab868312009-01-10 15:40:25 +00001279- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1280 common cases are optimized thanks to a dedicated fast path and a moderate
1281 amount of loop unrolling.
1282
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001283- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1284 collecting the oldest generation) so that allocating lots of objects without
1285 destroying them does not show quadratic performance. Based on a proposal by
1286 Martin von Löwis at
1287 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1288
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001289- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001290 having been closed (for instance, a read() call could return some
1291 previously buffered data). Patch by Dmitry Vasiliev.
1292
Antoine Pitrou05608432009-01-09 18:53:14 +00001293- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1294 flag to work properly. Furthermore, when specifying -u, the text stdout
1295 and stderr streams have line-by-line buffering enabled (the default being
1296 to buffer arbitrary chunks of data).
1297
Raymond Hettinger35631532009-01-09 03:58:09 +00001298- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1299 instead of ints (reducing its size from 4 to 8 times thereby reducing
1300 Python's overall memory).
1301
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001302- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1303 an existing .py counterpart, override the co_filename attributes of all
1304 code objects if the original filename is obsolete (which can happen if the
1305 file has been renamed, moved, or if it is accessed through different paths).
1306 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1307
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001308- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1309 one byte. Also fixes the meaning of len() so that it returns the number of
1310 items, rather than the size in bytes.
1311
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001312- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1313
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001314- Issue #4747: When the terminal does not use utf-8, executing a script with
1315 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1316

1325
Georg Brandlccc47b62008-12-28 11:44:14 +00001326- Issue #4759: None is now allowed as the first argument of

1328
Skip Montanaro80072cb2008-12-23 03:51:14 +00001329- Added test case to ensure attempts to read from a file opened for writing
1330 fail.

1345 failures on OS X.
1346
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001347- Issue #4597: Fixed several opcodes that weren't always propagating

1349
1350- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001351 context manager returns a value that cannot be converted to a bool.
1352
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001353- Issue #4445: Replace "sizeof(PyBytesObject)" with
1354 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1355 bytes instances. On a typical machine this saves 3 bytes of memory
1356 (on average) per allocation of a bytes instance.
1357
Christian Heimesa872de52008-12-05 08:26:55 +00001358- Issue #4533: File read operation was dreadfully slow due to a slowly
1359 growing read buffer. Fixed by using the same growth rate algorithm as
1360 Python 2.x.
1361
Antoine Pitrou5504e892008-12-06 21:27:53 +00001362- Issue #4509: Various issues surrounding resize of bytearray objects to

1364
Georg Brandlf9734072008-12-07 15:30:06 +00001365- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1366 method on file objects with closefd=False. The file descriptor is still
1367 kept open but the file object behaves like a closed file. The ``FileIO``
1368 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00001377- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1378 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1379 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1380 of using the replace error handler in PyUnicode_DecodeUTF8().
