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

Nick Coghlan260bd3e2009-11-16 06:49:25 +0000226- Issue #6816: runpy now provides a run_path function that allows Python code
227 to execute file paths that refer to source or compiled Python files as well
228 as zipfiles, directories and other valid sys.path entries that contain a
229 __main__.py file. This allows applications that run other Python scripts to
230 support the same flexibility as the CPython command line itself.
231
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000232- Issue #7318: multiprocessing now uses a timeout when it fails to establish

245
Antoine Pitroub0872682009-11-09 16:08:16 +0000246- Issue #7282: Fix a memory leak when an RLock was used in a thread other
247 than those started through `threading.Thread` (for example, using

260 a modification is done through it. This fixes inconsistencies and test
261 failures on systems with slightly bogus mtime behaviour.
262
Gregory P. Smith50467882009-11-01 18:42:17 +0000263- Issue #7246 & Issue #7208: getpass now properly flushes input before
264 reading from stdin so that existing input does not confuse it and
265 lead to incorrect entry or an IOError. It also properly flushes it
266 afterwards to avoid the terminal echoing the input afterwards on
267 OSes such as Solaris.
268
Mark Dickinsona2d1fe02009-10-29 12:23:02 +0000269- Issue #7233: Fix a number of two-argument Decimal methods to make

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

504 the road because the internally cached encoders and decoders would point
505 to empty global variables.
506

617
Benjamin Peterson0926ad12009-06-06 18:02:12 +0000618- Issue #6217: The C implementation of io.TextIOWrapper didn't include the
619 errors property. Additionally, the errors and encoding properties of StringIO
620 are always None now.
621
Antoine Pitroud9dfaa92009-06-04 20:32:06 +0000622- Issue #6137: The pickle module now translates module names when loading
623 or dumping pickles with a 2.x-compatible protocol, in order to make data
624 sharing and migration easier. This behaviour can be disabled using the
625 new `fix_imports` optional argument.

680 that would raise SystemError.
681
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000682- Issue #5982: staticmethod and classmethod now expose the wrapped
683 function with __func__.
684
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000685- Added support for multiple context managers in the same with-statement.
686 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000688- Issue #5829: complex("1e500") no longer raises OverflowError. This
689 makes it consistent with float("1e500") and interpretation of real
690 and imaginary literals.
691
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000692- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

695
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000696- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
697 (1) inf and nan strings with trailing whitespace were incorrectly
698 rejected; (2) parsing of strings representing infinities and nans
699 was locale aware; and (3) the interpretation of fromhex('-nan')
700 didn't match that of float('-nan').

713 arguments for strings with a space in them.
714
Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000715- collections.namedtuple() was not working with the following field
716 names: cls, self, tuple, itemgetter, and property.
717
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000718- In unittest, using a skipping decorator on a class is now equivalent to
719 skipping every test on the class. The ClassTestSuite class has been removed.
720
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000721- Issue #6050: Don't fail extracting a directory from a zipfile if
722 the directory already exists.
723
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000724- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
725 than an int, which makes some operations possible under 64-bit Linux (e.g.
726 DN_MULTISHOT with F_NOTIFY).
727

732 by Musashi Tamura, tests by Marcin Bachry.
733
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000734- Issue #1983: Fix functions taking or returning a process identifier to use
735 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
736 a process identifier type wider than the standard C integer type.
737
R. David Murray87e20742009-05-23 01:30:26 +0000738- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

749
Antoine Pitroue4501852009-05-14 18:55:55 +0000750- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
751 library. This means, for example, that opening an UTF-16 text file in
752 append mode doesn't add a BOM at the end of the file if the file isn't
753 empty.
754
R. David Murray74b89242009-05-13 17:33:03 +0000755- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
756 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
757 corrects a pydoc regression.
758
R. David Murray99352742009-05-07 18:24:38 +0000759- Issue 5955: aifc's close method did not close the file it wrapped,
760 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000798What's New in Python 3.1 beta 1?
799================================
800
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000801*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000802
803Core and Builtins
804-----------------
805
Mark Dickinson865e01a2009-05-07 16:37:01 +0000806- Issue #5914: Add new C API function PyOS_string_to_double, and
807 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
808
Eric Smith741191f2009-05-06 13:08:15 +0000809- Issue #3382: float.__format__, complex.__format__, and %-formatting
810 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
811 affects nan -> NAN and inf -> INF.
812
Mark Hammond5a607a32009-05-06 08:04:54 +0000813- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
814 in all operations, including splitdrive, split, etc. splitunc() now issues
815 a PendingDeprecation warning.
816
Eric Smith63376222009-05-05 14:04:18 +0000817- Issue #5920: For float.__format__, change the behavior with the
818 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
819 to be like 'g' but with at least one decimal point and with a
820 default precision of 12. Previously, the behavior the same but with
821 a default precision of 6. This more closely matches str(), and
822 reduces surprises when adding alignment flags to the empty
823 presentation type. This also affects the new complex.__format__ in
824 the same way.
825
Martin v. Löwis011e8422009-05-05 04:43:17 +0000826- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
827
R. David Murrayb18500d2009-05-04 22:59:07 +0000828- Issue #5890: in subclasses of 'property' the __doc__ attribute was
829 shadowed by classtype's, even if it was None. property now
830 inserts the __doc__ into the subclass instance __dict__.
831
Antoine Pitrou244651a2009-05-04 18:56:13 +0000832- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
833 sequences. Patch by Nick Barnes and Victor Stinner.
834
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000835- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000836
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000837- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
838 received a new method, detach(). detach() disconnects the underlying stream
839 from the buffer or text IO and returns it.
840
Mark Dickinson33841c32009-05-01 15:37:04 +0000841- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
842 floats with absolute value over 1e50. Also remove length
843 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
844 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000845
Eric Smith741191f2009-05-06 13:08:15 +0000846- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000847 format(complex(1, 2./3), '.5') now produces a sensible result.
848
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000849- Issue #5864: Fix empty format code formatting for floats so that it
850 never gives more than the requested number of significant digits.
851
Eric Smith6dc46f52009-04-27 20:39:49 +0000852- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
853 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
854
Eric Smithcc32a112009-04-26 21:35:14 +0000855- Issue #5835: Deprecate PyOS_ascii_formatd.
856
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000857- Issue #4971: Fix titlecase for characters that are their own
858 titlecase, but not their own uppercase.
859
Benjamin Peterson193152c2009-04-25 01:08:45 +0000860- Issue #5283: Setting __class__ in __del__ caused a segfault.
861
Mark Dickinsonad476da2009-04-23 19:14:16 +0000862- Issue #5816: complex(repr(z)) now recovers z exactly, even when
863 z involves nans, infs or negative zeros.
864
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000865- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000866
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000867- Issue #1869 (and many duplicates): make round(x, n) correctly
868 rounded for a float x, by using the decimal <-> binary conversions
869 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
870 consistently agrees with format(x, '.2f').
871
Benjamin Petersonae937c02009-04-18 20:54:08 +0000872- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
873 some builtin types.
874
Eric Smith0923d1d2009-04-16 20:16:10 +0000875- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
876
Eric Smith35e84722009-04-16 20:21:28 +0000877- Issue #5515: str.format() type 'n' combined with commas and leading
878 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000879
880- Implement PEP 378, Format Specifier for Thousands Separator, for
881 floats.
882
Mark Dickinson3370cce2009-04-17 22:40:53 +0000883- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000884 1e11, not 1e12. This avoids printing 13 significant digits in
885 situations where only 12 of them are correct. Example problem
886 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
887 long time.)
888
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000889- Issue #1580: On most platforms, use a 'short' float repr: for a
890 finite float x, repr(x) now outputs a string based on the shortest
891 sequence of decimal digits that rounds to x. Previous behaviour was
892 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000893 Another minor difference is that the new repr switches to
894 exponential notation at 1e16 instead of the previous 1e17; this
895 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000896
897 There's a new sys attribute sys.float_repr_style, which takes
898 the value 'short' to indicate that we're using short float repr,
899 and 'legacy' if the short float repr isn't available for one
900 reason or another.
901
902 The float repr change involves incorporating David Gay's 'perfect
903 rounding' code into the Python core (it's in Python/dtoa.c). As a
904 secondary consequence, all string-to-float and float-to-string
905 conversions (including all float formatting operations) will be
906 correctly rounded on these platforms.
907
908 See issue 1580 discussions for details of platforms for which
909 this change does not apply.
910
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000911- Issue #5759: float() didn't call __float__ on str subclasses.
912
Georg Brandlabc38772009-04-12 15:51:51 +0000913- The string.maketrans() function is deprecated; there is a new static method
914 maketrans() on the bytes and bytearray classes. This removes confusion about
915 the types string.maketrans() is supposed to work with, and mirrors the
916 methods available on the str class.

Mark Dickinsonc008a172009-02-01 13:59:22 +00001216- Issue #1717: Removed builtin cmp() function, dropped tp_compare
1217 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00001218 the type definition cmpfunc. The tp_compare slot has been renamed
1219 to tp_reserved, and is reserved for future usage.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00001221- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001222 were suppressing all exceptions. These include list() and bytearray().
1223
Mark Dickinson1124e712009-01-28 21:25:58 +00001224- Issue #4707: round(x, n) now returns an integer if x is an integer.
1225 Previously it returned a float.
1226
Antoine Pitroub52ec782009-01-25 16:34:23 +00001227- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1228 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1229 evaluation loop is compiled with a new dispatch mechanism which gives
1230 speedups of up to 20%, depending on the system, on various benchmarks.
1231
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001232- Issue #4874: Most builtin decoders now reject unicode input.

1235 from a string.
1236
Benjamin Peterson05e782f2009-01-19 15:15:02 +00001237- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
1238
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001239- Issue #4838: When a module is deallocated, free the memory backing the
1240 optional module state data.
1241
Mark Dickinson8055afd2009-01-17 10:04:45 +00001242- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1243 type to (void *).
1244
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001245- Issue #4935: The overflow checking code in the expandtabs() method common
1246 to str, bytes and bytearray could be optimized away by the compiler, letting
1247 the interpreter segfault instead of raising an error.
1248
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001249- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1250 __next__ method.
1251
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001252- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1253 function no longer attempt to call the __long__ slot to convert an object
1254 to an integer. Only the __int__ and __trunc__ slots are examined.

1259
Antoine Pitrouab868312009-01-10 15:40:25 +00001260- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1261 common cases are optimized thanks to a dedicated fast path and a moderate
1262 amount of loop unrolling.
1263
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001264- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1265 collecting the oldest generation) so that allocating lots of objects without
1266 destroying them does not show quadratic performance. Based on a proposal by
1267 Martin von Löwis at
1268 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1269
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001270- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001271 having been closed (for instance, a read() call could return some
1272 previously buffered data). Patch by Dmitry Vasiliev.
1273
Antoine Pitrou05608432009-01-09 18:53:14 +00001274- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1275 flag to work properly. Furthermore, when specifying -u, the text stdout
1276 and stderr streams have line-by-line buffering enabled (the default being
1277 to buffer arbitrary chunks of data).
1278
Raymond Hettinger35631532009-01-09 03:58:09 +00001279- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1280 instead of ints (reducing its size from 4 to 8 times thereby reducing
1281 Python's overall memory).
1282
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001283- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1284 an existing .py counterpart, override the co_filename attributes of all
1285 code objects if the original filename is obsolete (which can happen if the
1286 file has been renamed, moved, or if it is accessed through different paths).
1287 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1288
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001289- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1290 one byte. Also fixes the meaning of len() so that it returns the number of
1291 items, rather than the size in bytes.
1292
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001293- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1294
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001295- Issue #4747: When the terminal does not use utf-8, executing a script with
1296 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1297
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001298- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001299 file with `bytes' filename on Windows.

Antoine Pitrou7ddda782009-01-01 15:35:33 +00001301- Issue #3680: Reference cycles created through a dict, set or deque iterator
1302 did not get collected.
1303
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001304- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1305 where the tp_hash and tp_dict slots are both NULL.
1306
Georg Brandlccc47b62008-12-28 11:44:14 +00001307- Issue #4759: None is now allowed as the first argument of
1308 bytearray.translate(). It was always allowed for bytes.translate().
1309
Skip Montanaro80072cb2008-12-23 03:51:14 +00001310- Added test case to ensure attempts to read from a file opened for writing
1311 fail.
1312
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001313- Issue #3106: Speedup some comparisons (str/str and int/int).

1316 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1317
Antoine Pitrou621601a2008-12-17 23:18:19 +00001318- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1319 print elapsed times, not only when some objects are uncollectable /
1320 unreachable. Original patch by Neil Schemenauer.
1321
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001322- Issue #3439: Add a bit_length method to int.
1323
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001324- Issue #2173: When getting device encoding, check that return value of
1325 nl_langinfo is not the empty string. This was causing silent build
1326 failures on OS X.
1327
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001328- Issue #4597: Fixed several opcodes that weren't always propagating
1329 exceptions.
1330
1331- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001332 context manager returns a value that cannot be converted to a bool.
1333
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001334- Issue #4445: Replace "sizeof(PyBytesObject)" with
1335 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1336 bytes instances. On a typical machine this saves 3 bytes of memory
1337 (on average) per allocation of a bytes instance.
1338
Christian Heimesa872de52008-12-05 08:26:55 +00001339- Issue #4533: File read operation was dreadfully slow due to a slowly
1340 growing read buffer. Fixed by using the same growth rate algorithm as
1341 Python 2.x.
1342
Antoine Pitrou5504e892008-12-06 21:27:53 +00001343- Issue #4509: Various issues surrounding resize of bytearray objects to
1344 which there are buffer exports (e.g. memoryview instances).
1345
Georg Brandlf9734072008-12-07 15:30:06 +00001346- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1347 method on file objects with closefd=False. The file descriptor is still
1348 kept open but the file object behaves like a closed file. The ``FileIO``
1349 object also got a new readonly attribute ``closefd``.

1357
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001358- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1359 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1360 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1361 of using the replace error handler in PyUnicode_DecodeUTF8().
