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

219 to execute file paths that refer to source or compiled Python files as well
220 as zipfiles, directories and other valid sys.path entries that contain a
221 __main__.py file. This allows applications that run other Python scripts to
222 support the same flexibility as the CPython command line itself.
223
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000224- Issue #7318: multiprocessing now uses a timeout when it fails to establish

243 write new bytecode when it was made read-only.
244

253 failures on systems with slightly bogus mtime behaviour.
254
Gregory P. Smith50467882009-11-01 18:42:17 +0000255- Issue #7246 & Issue #7208: getpass now properly flushes input before
256 reading from stdin so that existing input does not confuse it and
257 lead to incorrect entry or an IOError. It also properly flushes it
258 afterwards to avoid the terminal echoing the input afterwards on
259 OSes such as Solaris.
260
Mark Dickinsona2d1fe02009-10-29 12:23:02 +0000261- Issue #7233: Fix a number of two-argument Decimal methods to make
262 sure that they accept an int or long as the second argument. Also
263 fix buggy handling of large arguments (those with coefficient longer
264 than the current precision) in shift and rotate.

496 the road because the internally cached encoders and decoders would point
497 to empty global variables.

611 errors property. Additionally, the errors and encoding properties of StringIO
612 are always None now.
613
Antoine Pitroud9dfaa92009-06-04 20:32:06 +0000614- Issue #6137: The pickle module now translates module names when loading
615 or dumping pickles with a 2.x-compatible protocol, in order to make data
616 sharing and migration easier. This behaviour can be disabled using the
617 new `fix_imports` optional argument.

672 that would raise SystemError.
673
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000674- Issue #5982: staticmethod and classmethod now expose the wrapped
675 function with __func__.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000680- Issue #5829: complex("1e500") no longer raises OverflowError. This
681 makes it consistent with float("1e500") and interpretation of real
682 and imaginary literals.
683
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000684- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

687
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000688- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
689 (1) inf and nan strings with trailing whitespace were incorrectly
690 rejected; (2) parsing of strings representing infinities and nans
691 was locale aware; and (3) the interpretation of fromhex('-nan')
692 didn't match that of float('-nan').

705 arguments for strings with a space in them.
706
Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000707- collections.namedtuple() was not working with the following field
708 names: cls, self, tuple, itemgetter, and property.
709
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000710- In unittest, using a skipping decorator on a class is now equivalent to
711 skipping every test on the class. The ClassTestSuite class has been removed.
712
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000713- Issue #6050: Don't fail extracting a directory from a zipfile if
714 the directory already exists.
715
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000716- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
717 than an int, which makes some operations possible under 64-bit Linux (e.g.
718 DN_MULTISHOT with F_NOTIFY).
719
Antoine Pitrou716c4442009-05-23 19:04:03 +0000720- Issue #5761: Add the name of the underlying file to the repr() of various

724 by Musashi Tamura, tests by Marcin Bachry.
725
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000726- Issue #1983: Fix functions taking or returning a process identifier to use
727 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
728 a process identifier type wider than the standard C integer type.
729
R. David Murray87e20742009-05-23 01:30:26 +0000730- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
731 Patch by Farhan Ahmad, test by Marcin Bachry.

741
Antoine Pitroue4501852009-05-14 18:55:55 +0000742- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
743 library. This means, for example, that opening an UTF-16 text file in
744 append mode doesn't add a BOM at the end of the file if the file isn't
745 empty.
746
R. David Murray74b89242009-05-13 17:33:03 +0000747- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
748 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
749 corrects a pydoc regression.
750
R. David Murray99352742009-05-07 18:24:38 +0000751- Issue 5955: aifc's close method did not close the file it wrapped,
752 now it does. This also means getfp method now returns the real fp.
753
Benjamin Peterson932073a2009-05-23 16:14:33 +0000754Installation
755------------

Brett Cannon1262e7c2009-05-11 01:47:11 +0000781Tests
782-----
783
784- Issue 5442: Tests for importlib were not properly skipping case-sensitivity

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000790What's New in Python 3.1 beta 1?
791================================

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000793*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000794
795Core and Builtins
796-----------------
797
Mark Dickinson865e01a2009-05-07 16:37:01 +0000798- Issue #5914: Add new C API function PyOS_string_to_double, and
799 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
800
Eric Smith741191f2009-05-06 13:08:15 +0000801- Issue #3382: float.__format__, complex.__format__, and %-formatting
802 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
803 affects nan -> NAN and inf -> INF.
804
Mark Hammond5a607a32009-05-06 08:04:54 +0000805- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
806 in all operations, including splitdrive, split, etc. splitunc() now issues
807 a PendingDeprecation warning.
808
Eric Smith63376222009-05-05 14:04:18 +0000809- Issue #5920: For float.__format__, change the behavior with the
810 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
811 to be like 'g' but with at least one decimal point and with a
812 default precision of 12. Previously, the behavior the same but with
813 a default precision of 6. This more closely matches str(), and
814 reduces surprises when adding alignment flags to the empty
815 presentation type. This also affects the new complex.__format__ in
816 the same way.
817
Martin v. Löwis011e8422009-05-05 04:43:17 +0000818- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
819
R. David Murrayb18500d2009-05-04 22:59:07 +0000820- Issue #5890: in subclasses of 'property' the __doc__ attribute was
821 shadowed by classtype's, even if it was None. property now
822 inserts the __doc__ into the subclass instance __dict__.
823
Antoine Pitrou244651a2009-05-04 18:56:13 +0000824- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
825 sequences. Patch by Nick Barnes and Victor Stinner.
826
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000827- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000828
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000829- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
830 received a new method, detach(). detach() disconnects the underlying stream
831 from the buffer or text IO and returns it.
832
Mark Dickinson33841c32009-05-01 15:37:04 +0000833- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
834 floats with absolute value over 1e50. Also remove length
835 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
836 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000837
Eric Smith741191f2009-05-06 13:08:15 +0000838- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000839 format(complex(1, 2./3), '.5') now produces a sensible result.
840
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000841- Issue #5864: Fix empty format code formatting for floats so that it
842 never gives more than the requested number of significant digits.
843
Eric Smith6dc46f52009-04-27 20:39:49 +0000844- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
845 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
846
Eric Smithcc32a112009-04-26 21:35:14 +0000847- Issue #5835: Deprecate PyOS_ascii_formatd.
848
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000849- Issue #4971: Fix titlecase for characters that are their own
850 titlecase, but not their own uppercase.
851
Benjamin Peterson193152c2009-04-25 01:08:45 +0000852- Issue #5283: Setting __class__ in __del__ caused a segfault.
853
Mark Dickinsonad476da2009-04-23 19:14:16 +0000854- Issue #5816: complex(repr(z)) now recovers z exactly, even when
855 z involves nans, infs or negative zeros.
856
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000857- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000858
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000859- Issue #1869 (and many duplicates): make round(x, n) correctly
860 rounded for a float x, by using the decimal <-> binary conversions
861 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
862 consistently agrees with format(x, '.2f').
863
Benjamin Petersonae937c02009-04-18 20:54:08 +0000864- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
865 some builtin types.
866
Eric Smith0923d1d2009-04-16 20:16:10 +0000867- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
868
Eric Smith35e84722009-04-16 20:21:28 +0000869- Issue #5515: str.format() type 'n' combined with commas and leading
870 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000871
872- Implement PEP 378, Format Specifier for Thousands Separator, for
873 floats.
874
Mark Dickinson3370cce2009-04-17 22:40:53 +0000875- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000876 1e11, not 1e12. This avoids printing 13 significant digits in
877 situations where only 12 of them are correct. Example problem
878 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
879 long time.)
880
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000881- Issue #1580: On most platforms, use a 'short' float repr: for a
882 finite float x, repr(x) now outputs a string based on the shortest
883 sequence of decimal digits that rounds to x. Previous behaviour was
884 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000885 Another minor difference is that the new repr switches to
886 exponential notation at 1e16 instead of the previous 1e17; this
887 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000888
889 There's a new sys attribute sys.float_repr_style, which takes
890 the value 'short' to indicate that we're using short float repr,
891 and 'legacy' if the short float repr isn't available for one
892 reason or another.
893
894 The float repr change involves incorporating David Gay's 'perfect
895 rounding' code into the Python core (it's in Python/dtoa.c). As a
896 secondary consequence, all string-to-float and float-to-string
897 conversions (including all float formatting operations) will be
898 correctly rounded on these platforms.
899
900 See issue 1580 discussions for details of platforms for which
901 this change does not apply.
902
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000903- Issue #5759: float() didn't call __float__ on str subclasses.
904
Georg Brandlabc38772009-04-12 15:51:51 +0000905- The string.maketrans() function is deprecated; there is a new static method
906 maketrans() on the bytes and bytearray classes. This removes confusion about
907 the types string.maketrans() is supposed to work with, and mirrors the
908 methods available on the str class.
909
R. David Murraydc6da8a2009-04-09 22:16:43 +0000910- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Georg Brandl1cdd83c2009-04-05 20:24:29 +00001213- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001214 were suppressing all exceptions. These include list() and bytearray().
1215
Mark Dickinson1124e712009-01-28 21:25:58 +00001216- Issue #4707: round(x, n) now returns an integer if x is an integer.
1217 Previously it returned a float.
1218
Antoine Pitroub52ec782009-01-25 16:34:23 +00001219- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1220 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1221 evaluation loop is compiled with a new dispatch mechanism which gives
1222 speedups of up to 20%, depending on the system, on various benchmarks.
1223
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001224- Issue #4874: Most builtin decoders now reject unicode input.

1232 optional module state data.
1233
Mark Dickinson8055afd2009-01-17 10:04:45 +00001234- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1235 type to (void *).
1236
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001237- Issue #4935: The overflow checking code in the expandtabs() method common
1238 to str, bytes and bytearray could be optimized away by the compiler, letting
1239 the interpreter segfault instead of raising an error.
1240
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001241- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1242 __next__ method.
1243
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001244- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1245 function no longer attempt to call the __long__ slot to convert an object
1246 to an integer. Only the __int__ and __trunc__ slots are examined.

1251
Antoine Pitrouab868312009-01-10 15:40:25 +00001252- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1253 common cases are optimized thanks to a dedicated fast path and a moderate
1254 amount of loop unrolling.
1255
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001256- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1257 collecting the oldest generation) so that allocating lots of objects without
1258 destroying them does not show quadratic performance. Based on a proposal by
1259 Martin von Löwis at
1260 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1261
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001262- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001263 having been closed (for instance, a read() call could return some
1264 previously buffered data). Patch by Dmitry Vasiliev.
1265
Antoine Pitrou05608432009-01-09 18:53:14 +00001266- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1267 flag to work properly. Furthermore, when specifying -u, the text stdout
1268 and stderr streams have line-by-line buffering enabled (the default being
1269 to buffer arbitrary chunks of data).
1270
Raymond Hettinger35631532009-01-09 03:58:09 +00001271- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1272 instead of ints (reducing its size from 4 to 8 times thereby reducing
1273 Python's overall memory).
1274
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001275- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1276 an existing .py counterpart, override the co_filename attributes of all
1277 code objects if the original filename is obsolete (which can happen if the
1278 file has been renamed, moved, or if it is accessed through different paths).
1279 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1280
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001281- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1282 one byte. Also fixes the meaning of len() so that it returns the number of
1283 items, rather than the size in bytes.
1284
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001285- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1286
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001287- Issue #4747: When the terminal does not use utf-8, executing a script with
1288 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1289
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001290- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

1294 did not get collected.
1295
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001296- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1297 where the tp_hash and tp_dict slots are both NULL.
1298
Georg Brandlccc47b62008-12-28 11:44:14 +00001299- Issue #4759: None is now allowed as the first argument of
1300 bytearray.translate(). It was always allowed for bytes.translate().
1301
Skip Montanaro80072cb2008-12-23 03:51:14 +00001302- Added test case to ensure attempts to read from a file opened for writing
1303 fail.
1304

1309
Antoine Pitrou621601a2008-12-17 23:18:19 +00001310- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1312 unreachable. Original patch by Neil Schemenauer.
1313

1315
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001316- Issue #2173: When getting device encoding, check that return value of
1317 nl_langinfo is not the empty string. This was causing silent build
1318 failures on OS X.
1319
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001320- Issue #4597: Fixed several opcodes that weren't always propagating
1321 exceptions.
1322
1323- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001324 context manager returns a value that cannot be converted to a bool.
1325
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001326- Issue #4445: Replace "sizeof(PyBytesObject)" with
1327 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1328 bytes instances. On a typical machine this saves 3 bytes of memory
1329 (on average) per allocation of a bytes instance.
1330
Christian Heimesa872de52008-12-05 08:26:55 +00001331- Issue #4533: File read operation was dreadfully slow due to a slowly
1332 growing read buffer. Fixed by using the same growth rate algorithm as
1333 Python 2.x.
1334
Antoine Pitrou5504e892008-12-06 21:27:53 +00001335- Issue #4509: Various issues surrounding resize of bytearray objects to
1336 which there are buffer exports (e.g. memoryview instances).
1337
Georg Brandlf9734072008-12-07 15:30:06 +00001338- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1339 method on file objects with closefd=False. The file descriptor is still
1340 kept open but the file object behaves like a closed file. The ``FileIO``
1341 object also got a new readonly attribute ``closefd``.

1349
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001350- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1351 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1352 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1353 of using the replace error handler in PyUnicode_DecodeUTF8().
