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

265 recursive locks as fast as regular non-recursive locks (previously,
266 they were slower by 10x to 15x).
267
Antoine Pitroub0872682009-11-09 16:08:16 +0000268- Issue #7282: Fix a memory leak when an RLock was used in a thread other

286 reading from stdin so that existing input does not confuse it and
287 lead to incorrect entry or an IOError. It also properly flushes it
288 afterwards to avoid the terminal echoing the input afterwards on
289 OSes such as Solaris.

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

781 library. This means, for example, that opening an UTF-16 text file in
782 append mode doesn't add a BOM at the end of the file if the file isn't
783 empty.

833Core and Builtins
834-----------------
835
Mark Dickinson865e01a2009-05-07 16:37:01 +0000836- Issue #5914: Add new C API function PyOS_string_to_double, and
837 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
838
Eric Smith741191f2009-05-06 13:08:15 +0000839- Issue #3382: float.__format__, complex.__format__, and %-formatting
840 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
841 affects nan -> NAN and inf -> INF.
842
Mark Hammond5a607a32009-05-06 08:04:54 +0000843- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
844 in all operations, including splitdrive, split, etc. splitunc() now issues
845 a PendingDeprecation warning.
846
Eric Smith63376222009-05-05 14:04:18 +0000847- Issue #5920: For float.__format__, change the behavior with the
848 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
849 to be like 'g' but with at least one decimal point and with a
850 default precision of 12. Previously, the behavior the same but with
851 a default precision of 6. This more closely matches str(), and
852 reduces surprises when adding alignment flags to the empty
853 presentation type. This also affects the new complex.__format__ in
854 the same way.
855
Martin v. Löwis011e8422009-05-05 04:43:17 +0000856- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

Martin v. Löwisdb12d452009-05-02 18:52:14 +0000866
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000867- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
868 received a new method, detach(). detach() disconnects the underlying stream
869 from the buffer or text IO and returns it.
870
Mark Dickinson33841c32009-05-01 15:37:04 +0000871- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
872 floats with absolute value over 1e50. Also remove length
873 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
874 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000875

880 never gives more than the requested number of significant digits.
881
Eric Smith6dc46f52009-04-27 20:39:49 +0000882- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
883 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
884

Mark Dickinsonad476da2009-04-23 19:14:16 +0000892- Issue #5816: complex(repr(z)) now recovers z exactly, even when
893 z involves nans, infs or negative zeros.

Mark Dickinsone6a076d2009-04-18 11:48:33 +0000897- Issue #1869 (and many duplicates): make round(x, n) correctly
898 rounded for a float x, by using the decimal <-> binary conversions
899 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
900 consistently agrees with format(x, '.2f').
901
Benjamin Petersonae937c02009-04-18 20:54:08 +0000902- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

906
Eric Smith35e84722009-04-16 20:21:28 +0000907- Issue #5515: str.format() type 'n' combined with commas and leading
908 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000909
910- Implement PEP 378, Format Specifier for Thousands Separator, for
911 floats.
912
Mark Dickinson3370cce2009-04-17 22:40:53 +0000913- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000914 1e11, not 1e12. This avoids printing 13 significant digits in
915 situations where only 12 of them are correct. Example problem
916 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
917 long time.)
918
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000919- Issue #1580: On most platforms, use a 'short' float repr: for a
920 finite float x, repr(x) now outputs a string based on the shortest
921 sequence of decimal digits that rounds to x. Previous behaviour was
922 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000923 Another minor difference is that the new repr switches to
924 exponential notation at 1e16 instead of the previous 1e17; this
925 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000926
927 There's a new sys attribute sys.float_repr_style, which takes
928 the value 'short' to indicate that we're using short float repr,
929 and 'legacy' if the short float repr isn't available for one
930 reason or another.
931
932 The float repr change involves incorporating David Gay's 'perfect
933 rounding' code into the Python core (it's in Python/dtoa.c). As a
934 secondary consequence, all string-to-float and float-to-string
935 conversions (including all float formatting operations) will be
936 correctly rounded on these platforms.
937
938 See issue 1580 discussions for details of platforms for which
939 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000941- Issue #5759: float() didn't call __float__ on str subclasses.
942
Georg Brandlabc38772009-04-12 15:51:51 +0000943- The string.maketrans() function is deprecated; there is a new static method
944 maketrans() on the bytes and bytearray classes. This removes confusion about
945 the types string.maketrans() is supposed to work with, and mirrors the
946 methods available on the str class.

1234
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001235- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1236 rotating the object pointer by 4 bits to the right.
1237
Mark Dickinson87ec0852009-02-09 17:15:59 +00001238- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1239 it now forces its argument to double before testing for infinity.
1240
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001241- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001250
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001251- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001252 were suppressing all exceptions. These include list() and bytearray().

1256
Antoine Pitroub52ec782009-01-25 16:34:23 +00001257- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1258 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1259 evaluation loop is compiled with a new dispatch mechanism which gives
1260 speedups of up to 20%, depending on the system, on various benchmarks.
1261
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001262- Issue #4874: Most builtin decoders now reject unicode input.

1268
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001269- Issue #4838: When a module is deallocated, free the memory backing the
1270 optional module state data.
1271
Mark Dickinson8055afd2009-01-17 10:04:45 +00001272- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1273 type to (void *).
1274
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001275- Issue #4935: The overflow checking code in the expandtabs() method common
1276 to str, bytes and bytearray could be optimized away by the compiler, letting
1277 the interpreter segfault instead of raising an error.
1278
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001279- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1280 __next__ method.
1281
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001282- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1283 function no longer attempt to call the __long__ slot to convert an object
1284 to an integer. Only the __int__ and __trunc__ slots are examined.
1285
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001286- Issue #4893: Use NT threading on CE.
1287
Martin v. Löwisec59d042009-01-12 07:59:10 +00001288- Issue #4915: Port sysmodule to Windows CE.
1289
Antoine Pitrouab868312009-01-10 15:40:25 +00001290- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1291 common cases are optimized thanks to a dedicated fast path and a moderate
1292 amount of loop unrolling.
1293
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001294- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1295 collecting the oldest generation) so that allocating lots of objects without
1296 destroying them does not show quadratic performance. Based on a proposal by
1297 Martin von Löwis at
1298 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1299
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001300- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001301 having been closed (for instance, a read() call could return some
1302 previously buffered data). Patch by Dmitry Vasiliev.
1303
Antoine Pitrou05608432009-01-09 18:53:14 +00001304- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1305 flag to work properly. Furthermore, when specifying -u, the text stdout
1306 and stderr streams have line-by-line buffering enabled (the default being
1307 to buffer arbitrary chunks of data).
1308
Raymond Hettinger35631532009-01-09 03:58:09 +00001309- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1310 instead of ints (reducing its size from 4 to 8 times thereby reducing
1311 Python's overall memory).
1312
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001313- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1314 an existing .py counterpart, override the co_filename attributes of all
1315 code objects if the original filename is obsolete (which can happen if the
1316 file has been renamed, moved, or if it is accessed through different paths).
1317 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1318
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001319- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1320 one byte. Also fixes the meaning of len() so that it returns the number of
1321 items, rather than the size in bytes.
1322
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001323- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1324
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001325- Issue #4747: When the terminal does not use utf-8, executing a script with
1326 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1327
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001328- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001329 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001330
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001331- Issue #3680: Reference cycles created through a dict, set or deque iterator
1332 did not get collected.
1333
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001334- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1335 where the tp_hash and tp_dict slots are both NULL.
1336
Georg Brandlccc47b62008-12-28 11:44:14 +00001337- Issue #4759: None is now allowed as the first argument of
1338 bytearray.translate(). It was always allowed for bytes.translate().
1339
Skip Montanaro80072cb2008-12-23 03:51:14 +00001340- Added test case to ensure attempts to read from a file opened for writing
1341 fail.
1342
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001343- Issue #3106: Speedup some comparisons (str/str and int/int).

1347
Antoine Pitrou621601a2008-12-17 23:18:19 +00001348- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1349 print elapsed times, not only when some objects are uncollectable /
1350 unreachable. Original patch by Neil Schemenauer.
1351
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001352- Issue #3439: Add a bit_length method to int.
1353
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001354- Issue #2173: When getting device encoding, check that return value of
1355 nl_langinfo is not the empty string. This was causing silent build
1356 failures on OS X.
1357
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001358- Issue #4597: Fixed several opcodes that weren't always propagating
1359 exceptions.
1360
1361- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001362 context manager returns a value that cannot be converted to a bool.
1363
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001364- Issue #4445: Replace "sizeof(PyBytesObject)" with
1365 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1366 bytes instances. On a typical machine this saves 3 bytes of memory
1367 (on average) per allocation of a bytes instance.
1368
Christian Heimesa872de52008-12-05 08:26:55 +00001369- Issue #4533: File read operation was dreadfully slow due to a slowly
1370 growing read buffer. Fixed by using the same growth rate algorithm as
1371 Python 2.x.
1372
Antoine Pitrou5504e892008-12-06 21:27:53 +00001373- Issue #4509: Various issues surrounding resize of bytearray objects to
1374 which there are buffer exports (e.g. memoryview instances).
1375
Georg Brandlf9734072008-12-07 15:30:06 +00001376- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1377 method on file objects with closefd=False. The file descriptor is still
1378 kept open but the file object behaves like a closed file. The ``FileIO``
1379 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001380
Antoine Pitroubc420402008-12-07 20:14:49 +00001381- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1382 larger than 1.

1387
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001388- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1389 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1390 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1391 of using the replace error handler in PyUnicode_DecodeUTF8().
