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.

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

744
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000745- Issue #6050: Don't fail extracting a directory from a zipfile if

747
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000748- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
749 than an int, which makes some operations possible under 64-bit Linux (e.g.

Antoine Pitroue4501852009-05-14 18:55:55 +0000774- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
775 library. This means, for example, that opening an UTF-16 text file in
776 append mode doesn't add a BOM at the end of the file if the file isn't
777 empty.
778
R. David Murray74b89242009-05-13 17:33:03 +0000779- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

781 corrects a pydoc regression.
782
R. David Murray99352742009-05-07 18:24:38 +0000783- Issue 5955: aifc's close method did not close the file it wrapped,
784 now it does. This also means getfp method now returns the real fp.

827Core and Builtins
828-----------------
829
Mark Dickinson865e01a2009-05-07 16:37:01 +0000830- Issue #5914: Add new C API function PyOS_string_to_double, and
831 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
832
Eric Smith741191f2009-05-06 13:08:15 +0000833- Issue #3382: float.__format__, complex.__format__, and %-formatting
834 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
835 affects nan -> NAN and inf -> INF.
836
Mark Hammond5a607a32009-05-06 08:04:54 +0000837- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
838 in all operations, including splitdrive, split, etc. splitunc() now issues
839 a PendingDeprecation warning.
840
Eric Smith63376222009-05-05 14:04:18 +0000841- Issue #5920: For float.__format__, change the behavior with the
842 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
843 to be like 'g' but with at least one decimal point and with a
844 default precision of 12. Previously, the behavior the same but with
845 a default precision of 6. This more closely matches str(), and
846 reduces surprises when adding alignment flags to the empty
847 presentation type. This also affects the new complex.__format__ in
848 the same way.
849
Martin v. Löwis011e8422009-05-05 04:43:17 +0000850- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
851
R. David Murrayb18500d2009-05-04 22:59:07 +0000852- Issue #5890: in subclasses of 'property' the __doc__ attribute was
853 shadowed by classtype's, even if it was None. property now
854 inserts the __doc__ into the subclass instance __dict__.
855
Antoine Pitrou244651a2009-05-04 18:56:13 +0000856- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

858
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000859- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000860
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000861- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
862 received a new method, detach(). detach() disconnects the underlying stream
863 from the buffer or text IO and returns it.
864
Mark Dickinson33841c32009-05-01 15:37:04 +0000865- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
866 floats with absolute value over 1e50. Also remove length
867 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
868 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000869
Eric Smith741191f2009-05-06 13:08:15 +0000870- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000871 format(complex(1, 2./3), '.5') now produces a sensible result.
872
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000873- Issue #5864: Fix empty format code formatting for floats so that it
874 never gives more than the requested number of significant digits.
875
Eric Smith6dc46f52009-04-27 20:39:49 +0000876- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
877 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
878
Eric Smithcc32a112009-04-26 21:35:14 +0000879- Issue #5835: Deprecate PyOS_ascii_formatd.
880

882 titlecase, but not their own uppercase.
883
Benjamin Peterson193152c2009-04-25 01:08:45 +0000884- Issue #5283: Setting __class__ in __del__ caused a segfault.
885
Mark Dickinsonad476da2009-04-23 19:14:16 +0000886- Issue #5816: complex(repr(z)) now recovers z exactly, even when
887 z involves nans, infs or negative zeros.
888
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000889- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000890
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000891- Issue #1869 (and many duplicates): make round(x, n) correctly
892 rounded for a float x, by using the decimal <-> binary conversions
893 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
894 consistently agrees with format(x, '.2f').
895
Benjamin Petersonae937c02009-04-18 20:54:08 +0000896- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

902 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000903
904- Implement PEP 378, Format Specifier for Thousands Separator, for
905 floats.
906
Mark Dickinson3370cce2009-04-17 22:40:53 +0000907- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000908 1e11, not 1e12. This avoids printing 13 significant digits in
909 situations where only 12 of them are correct. Example problem
910 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
911 long time.)
912
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000913- Issue #1580: On most platforms, use a 'short' float repr: for a
914 finite float x, repr(x) now outputs a string based on the shortest
915 sequence of decimal digits that rounds to x. Previous behaviour was
916 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000917 Another minor difference is that the new repr switches to
918 exponential notation at 1e16 instead of the previous 1e17; this
919 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000920
921 There's a new sys attribute sys.float_repr_style, which takes
922 the value 'short' to indicate that we're using short float repr,
923 and 'legacy' if the short float repr isn't available for one
924 reason or another.
925
926 The float repr change involves incorporating David Gay's 'perfect
927 rounding' code into the Python core (it's in Python/dtoa.c). As a
928 secondary consequence, all string-to-float and float-to-string
929 conversions (including all float formatting operations) will be
930 correctly rounded on these platforms.
931
932 See issue 1580 discussions for details of platforms for which
933 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000935- Issue #5759: float() didn't call __float__ on str subclasses.
936
Georg Brandlabc38772009-04-12 15:51:51 +0000937- The string.maketrans() function is deprecated; there is a new static method
938 maketrans() on the bytes and bytearray classes. This removes confusion about
939 the types string.maketrans() is supposed to work with, and mirrors the
940 methods available on the str class.

1221 used when using str.format() with str, int, and float arguments.
1222
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00001223- Issue #5249: time.strftime returned malformed string when format string
1224 contained non ascii character on windows.
1225
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001226- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1227 source has already been decoded into str.
1228
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001229- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1230 rotating the object pointer by 4 bits to the right.
1231
Mark Dickinson87ec0852009-02-09 17:15:59 +00001232- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1233 it now forces its argument to double before testing for infinity.
1234
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001235- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

1243 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001244
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001245- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001246 were suppressing all exceptions. These include list() and bytearray().
1247
Mark Dickinson1124e712009-01-28 21:25:58 +00001248- Issue #4707: round(x, n) now returns an integer if x is an integer.
1249 Previously it returned a float.
1250
Antoine Pitroub52ec782009-01-25 16:34:23 +00001251- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1252 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1253 evaluation loop is compiled with a new dispatch mechanism which gives
1254 speedups of up to 20%, depending on the system, on various benchmarks.
1255
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001256- Issue #4874: Most builtin decoders now reject unicode input.

1260
Benjamin Peterson05e782f2009-01-19 15:15:02 +00001261- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
1262
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001263- Issue #4838: When a module is deallocated, free the memory backing the
1264 optional module state data.
1265
Mark Dickinson8055afd2009-01-17 10:04:45 +00001266- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1267 type to (void *).
1268
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001269- Issue #4935: The overflow checking code in the expandtabs() method common
1270 to str, bytes and bytearray could be optimized away by the compiler, letting
1271 the interpreter segfault instead of raising an error.
1272
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001273- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1274 __next__ method.
1275
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001276- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1277 function no longer attempt to call the __long__ slot to convert an object
1278 to an integer. Only the __int__ and __trunc__ slots are examined.
1279
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001280- Issue #4893: Use NT threading on CE.
1281
Martin v. Löwisec59d042009-01-12 07:59:10 +00001282- Issue #4915: Port sysmodule to Windows CE.
1283
Antoine Pitrouab868312009-01-10 15:40:25 +00001284- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1285 common cases are optimized thanks to a dedicated fast path and a moderate
1286 amount of loop unrolling.
1287
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001288- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1289 collecting the oldest generation) so that allocating lots of objects without
1290 destroying them does not show quadratic performance. Based on a proposal by
1291 Martin von Löwis at
1292 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1293
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001294- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001295 having been closed (for instance, a read() call could return some
1296 previously buffered data). Patch by Dmitry Vasiliev.
1297
Antoine Pitrou05608432009-01-09 18:53:14 +00001298- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1299 flag to work properly. Furthermore, when specifying -u, the text stdout
1300 and stderr streams have line-by-line buffering enabled (the default being
1301 to buffer arbitrary chunks of data).
1302
Raymond Hettinger35631532009-01-09 03:58:09 +00001303- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1304 instead of ints (reducing its size from 4 to 8 times thereby reducing
1305 Python's overall memory).
1306
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001307- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1308 an existing .py counterpart, override the co_filename attributes of all
1309 code objects if the original filename is obsolete (which can happen if the
1310 file has been renamed, moved, or if it is accessed through different paths).
1311 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1312
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001313- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1314 one byte. Also fixes the meaning of len() so that it returns the number of
1315 items, rather than the size in bytes.
1316
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001317- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1318
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001319- Issue #4747: When the terminal does not use utf-8, executing a script with
1320 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1321
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001322- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001323 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001324
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001325- Issue #3680: Reference cycles created through a dict, set or deque iterator
1326 did not get collected.
1327
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001328- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1329 where the tp_hash and tp_dict slots are both NULL.
1330
Georg Brandlccc47b62008-12-28 11:44:14 +00001331- Issue #4759: None is now allowed as the first argument of
1332 bytearray.translate(). It was always allowed for bytes.translate().
1333
Skip Montanaro80072cb2008-12-23 03:51:14 +00001334- Added test case to ensure attempts to read from a file opened for writing
1335 fail.
1336
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001337- Issue #3106: Speedup some comparisons (str/str and int/int).

1341
Antoine Pitrou621601a2008-12-17 23:18:19 +00001342- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1343 print elapsed times, not only when some objects are uncollectable /
1344 unreachable. Original patch by Neil Schemenauer.
1345
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001346- Issue #3439: Add a bit_length method to int.
1347
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001348- Issue #2173: When getting device encoding, check that return value of
1349 nl_langinfo is not the empty string. This was causing silent build
1350 failures on OS X.
1351
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001352- Issue #4597: Fixed several opcodes that weren't always propagating
1353 exceptions.
1354
1355- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001356 context manager returns a value that cannot be converted to a bool.
1357
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001358- Issue #4445: Replace "sizeof(PyBytesObject)" with
1359 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1360 bytes instances. On a typical machine this saves 3 bytes of memory
1361 (on average) per allocation of a bytes instance.
1362
Christian Heimesa872de52008-12-05 08:26:55 +00001363- Issue #4533: File read operation was dreadfully slow due to a slowly
1364 growing read buffer. Fixed by using the same growth rate algorithm as
1365 Python 2.x.
1366
Antoine Pitrou5504e892008-12-06 21:27:53 +00001367- Issue #4509: Various issues surrounding resize of bytearray objects to
1368 which there are buffer exports (e.g. memoryview instances).
1369
Georg Brandlf9734072008-12-07 15:30:06 +00001370- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1371 method on file objects with closefd=False. The file descriptor is still
1372 kept open but the file object behaves like a closed file. The ``FileIO``
1373 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001374
Antoine Pitroubc420402008-12-07 20:14:49 +00001375- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1381
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001382- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1383 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1384 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1385 of using the replace error handler in PyUnicode_DecodeUTF8().
