143 object at a specified file, function, and line number.
144
145- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
146 ``const char *`` as the string is stored beyond the call.

222 to execute file paths that refer to source or compiled Python files as well
223 as zipfiles, directories and other valid sys.path entries that contain a
224 __main__.py file. This allows applications that run other Python scripts to
225 support the same flexibility as the CPython command line itself.
226
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000227- Issue #7318: multiprocessing now uses a timeout when it fails to establish

255 a modification is done through it. This fixes inconsistencies and test
256 failures on systems with slightly bogus mtime behaviour.
257
Gregory P. Smith50467882009-11-01 18:42:17 +0000258- Issue #7246 & Issue #7208: getpass now properly flushes input before
259 reading from stdin so that existing input does not confuse it and
260 lead to incorrect entry or an IOError. It also properly flushes it
261 afterwards to avoid the terminal echoing the input afterwards on
262 OSes such as Solaris.
263
Mark Dickinsona2d1fe02009-10-29 12:23:02 +0000264- Issue #7233: Fix a number of two-argument Decimal methods to make

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

499 the road because the internally cached encoders and decoders would point
500 to empty global variables.

615 are always None now.
616
Antoine Pitroud9dfaa92009-06-04 20:32:06 +0000617- Issue #6137: The pickle module now translates module names when loading
618 or dumping pickles with a 2.x-compatible protocol, in order to make data
619 sharing and migration easier. This behaviour can be disabled using the
620 new `fix_imports` optional argument.

675 that would raise SystemError.
676
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000677- Issue #5982: staticmethod and classmethod now expose the wrapped
678 function with __func__.
679
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000680- Added support for multiple context managers in the same with-statement.
681 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +0000682
Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000683- Issue #5829: complex("1e500") no longer raises OverflowError. This
684 makes it consistent with float("1e500") and interpretation of real
685 and imaginary literals.
686
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000687- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

690
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000691- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
692 (1) inf and nan strings with trailing whitespace were incorrectly
693 rejected; (2) parsing of strings representing infinities and nans
694 was locale aware; and (3) the interpretation of fromhex('-nan')
695 didn't match that of float('-nan').

703
R. David Murray1f1b9d32009-05-27 20:56:59 +0000704- Issue #6121: pydoc now ignores leading and trailing spaces in the
705 argument to the 'help' function.
706
Georg Brandlfaf41492009-05-26 18:31:11 +0000707- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
708 arguments for strings with a space in them.
709
Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000710- collections.namedtuple() was not working with the following field
711 names: cls, self, tuple, itemgetter, and property.
712
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000713- In unittest, using a skipping decorator on a class is now equivalent to
714 skipping every test on the class. The ClassTestSuite class has been removed.
715
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000716- Issue #6050: Don't fail extracting a directory from a zipfile if
717 the directory already exists.
718
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000719- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
720 than an int, which makes some operations possible under 64-bit Linux (e.g.
721 DN_MULTISHOT with F_NOTIFY).
722
Antoine Pitrou716c4442009-05-23 19:04:03 +0000723- Issue #5761: Add the name of the underlying file to the repr() of various

725
R. David Murraycaa27b72009-05-23 18:49:56 +0000726- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
727 by Musashi Tamura, tests by Marcin Bachry.
728
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000729- Issue #1983: Fix functions taking or returning a process identifier to use
730 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
731 a process identifier type wider than the standard C integer type.
732
R. David Murray87e20742009-05-23 01:30:26 +0000733- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
734 Patch by Farhan Ahmad, test by Marcin Bachry.
735

737 deepcopy()ing.
738

744
Antoine Pitroue4501852009-05-14 18:55:55 +0000745- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
746 library. This means, for example, that opening an UTF-16 text file in
747 append mode doesn't add a BOM at the end of the file if the file isn't
748 empty.
749
R. David Murray74b89242009-05-13 17:33:03 +0000750- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
751 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
752 corrects a pydoc regression.
753
R. David Murray99352742009-05-07 18:24:38 +0000754- Issue 5955: aifc's close method did not close the file it wrapped,
755 now it does. This also means getfp method now returns the real fp.
756
Benjamin Peterson932073a2009-05-23 16:14:33 +0000757Installation
758------------

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000797
798Core and Builtins
799-----------------
800
Mark Dickinson865e01a2009-05-07 16:37:01 +0000801- Issue #5914: Add new C API function PyOS_string_to_double, and
802 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
803
Eric Smith741191f2009-05-06 13:08:15 +0000804- Issue #3382: float.__format__, complex.__format__, and %-formatting
805 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
806 affects nan -> NAN and inf -> INF.
807
Mark Hammond5a607a32009-05-06 08:04:54 +0000808- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
809 in all operations, including splitdrive, split, etc. splitunc() now issues
810 a PendingDeprecation warning.
811
Eric Smith63376222009-05-05 14:04:18 +0000812- Issue #5920: For float.__format__, change the behavior with the
813 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
814 to be like 'g' but with at least one decimal point and with a
815 default precision of 12. Previously, the behavior the same but with
816 a default precision of 6. This more closely matches str(), and
817 reduces surprises when adding alignment flags to the empty
818 presentation type. This also affects the new complex.__format__ in
819 the same way.
820
Martin v. Löwis011e8422009-05-05 04:43:17 +0000821- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
822
R. David Murrayb18500d2009-05-04 22:59:07 +0000823- Issue #5890: in subclasses of 'property' the __doc__ attribute was
824 shadowed by classtype's, even if it was None. property now
825 inserts the __doc__ into the subclass instance __dict__.
826
Antoine Pitrou244651a2009-05-04 18:56:13 +0000827- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
828 sequences. Patch by Nick Barnes and Victor Stinner.
829
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000830- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000831
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000832- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
833 received a new method, detach(). detach() disconnects the underlying stream
834 from the buffer or text IO and returns it.
835
Mark Dickinson33841c32009-05-01 15:37:04 +0000836- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
837 floats with absolute value over 1e50. Also remove length
838 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
839 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000840
Eric Smith741191f2009-05-06 13:08:15 +0000841- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000842 format(complex(1, 2./3), '.5') now produces a sensible result.
843
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000844- Issue #5864: Fix empty format code formatting for floats so that it
845 never gives more than the requested number of significant digits.
846
Eric Smith6dc46f52009-04-27 20:39:49 +0000847- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
848 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
849
Eric Smithcc32a112009-04-26 21:35:14 +0000850- Issue #5835: Deprecate PyOS_ascii_formatd.
851
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000852- Issue #4971: Fix titlecase for characters that are their own
853 titlecase, but not their own uppercase.
854
Benjamin Peterson193152c2009-04-25 01:08:45 +0000855- Issue #5283: Setting __class__ in __del__ caused a segfault.
856
Mark Dickinsonad476da2009-04-23 19:14:16 +0000857- Issue #5816: complex(repr(z)) now recovers z exactly, even when
858 z involves nans, infs or negative zeros.
859
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000860- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000861
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000862- Issue #1869 (and many duplicates): make round(x, n) correctly
863 rounded for a float x, by using the decimal <-> binary conversions
864 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
865 consistently agrees with format(x, '.2f').
866
Benjamin Petersonae937c02009-04-18 20:54:08 +0000867- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
868 some builtin types.
869
Eric Smith0923d1d2009-04-16 20:16:10 +0000870- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
871
Eric Smith35e84722009-04-16 20:21:28 +0000872- Issue #5515: str.format() type 'n' combined with commas and leading
873 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000874
875- Implement PEP 378, Format Specifier for Thousands Separator, for
876 floats.
877
Mark Dickinson3370cce2009-04-17 22:40:53 +0000878- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000879 1e11, not 1e12. This avoids printing 13 significant digits in
880 situations where only 12 of them are correct. Example problem
881 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
882 long time.)
883
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000884- Issue #1580: On most platforms, use a 'short' float repr: for a
885 finite float x, repr(x) now outputs a string based on the shortest
886 sequence of decimal digits that rounds to x. Previous behaviour was
887 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000888 Another minor difference is that the new repr switches to
889 exponential notation at 1e16 instead of the previous 1e17; this
890 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000891
892 There's a new sys attribute sys.float_repr_style, which takes
893 the value 'short' to indicate that we're using short float repr,
894 and 'legacy' if the short float repr isn't available for one
895 reason or another.
896
897 The float repr change involves incorporating David Gay's 'perfect
898 rounding' code into the Python core (it's in Python/dtoa.c). As a
899 secondary consequence, all string-to-float and float-to-string
900 conversions (including all float formatting operations) will be
901 correctly rounded on these platforms.
902
903 See issue 1580 discussions for details of platforms for which
904 this change does not apply.
905
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000906- Issue #5759: float() didn't call __float__ on str subclasses.
907
Georg Brandlabc38772009-04-12 15:51:51 +0000908- The string.maketrans() function is deprecated; there is a new static method
909 maketrans() on the bytes and bytearray classes. This removes confusion about
910 the types string.maketrans() is supposed to work with, and mirrors the
911 methods available on the str class.
912
R. David Murraydc6da8a2009-04-09 22:16:43 +0000913- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Georg Brandl1cdd83c2009-04-05 20:24:29 +00001216- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001217 were suppressing all exceptions. These include list() and bytearray().
1218
Mark Dickinson1124e712009-01-28 21:25:58 +00001219- Issue #4707: round(x, n) now returns an integer if x is an integer.
1220 Previously it returned a float.
1221
Antoine Pitroub52ec782009-01-25 16:34:23 +00001222- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1223 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1224 evaluation loop is compiled with a new dispatch mechanism which gives
1225 speedups of up to 20%, depending on the system, on various benchmarks.
1226
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001227- Issue #4874: Most builtin decoders now reject unicode input.

1236
Mark Dickinson8055afd2009-01-17 10:04:45 +00001237- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1238 type to (void *).
1239
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001240- Issue #4935: The overflow checking code in the expandtabs() method common
1241 to str, bytes and bytearray could be optimized away by the compiler, letting
1242 the interpreter segfault instead of raising an error.
1243
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001244- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1245 __next__ method.
1246
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001247- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1248 function no longer attempt to call the __long__ slot to convert an object
1249 to an integer. Only the __int__ and __trunc__ slots are examined.

1254
Antoine Pitrouab868312009-01-10 15:40:25 +00001255- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1256 common cases are optimized thanks to a dedicated fast path and a moderate
1257 amount of loop unrolling.
1258
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001259- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1260 collecting the oldest generation) so that allocating lots of objects without
1261 destroying them does not show quadratic performance. Based on a proposal by
1262 Martin von Löwis at
1263 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1264
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001265- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001266 having been closed (for instance, a read() call could return some
1267 previously buffered data). Patch by Dmitry Vasiliev.
1268
Antoine Pitrou05608432009-01-09 18:53:14 +00001269- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1270 flag to work properly. Furthermore, when specifying -u, the text stdout
1271 and stderr streams have line-by-line buffering enabled (the default being
1272 to buffer arbitrary chunks of data).
1273
Raymond Hettinger35631532009-01-09 03:58:09 +00001274- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1275 instead of ints (reducing its size from 4 to 8 times thereby reducing
1276 Python's overall memory).
1277
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001278- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1279 an existing .py counterpart, override the co_filename attributes of all
1280 code objects if the original filename is obsolete (which can happen if the
1281 file has been renamed, moved, or if it is accessed through different paths).
1282 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1283
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001284- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1285 one byte. Also fixes the meaning of len() so that it returns the number of
1286 items, rather than the size in bytes.
1287
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001288- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1289
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001290- Issue #4747: When the terminal does not use utf-8, executing a script with
1291 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1292
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001293- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

1297 did not get collected.
1298
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001299- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1300 where the tp_hash and tp_dict slots are both NULL.
1301
Georg Brandlccc47b62008-12-28 11:44:14 +00001302- Issue #4759: None is now allowed as the first argument of
1303 bytearray.translate(). It was always allowed for bytes.translate().
1304
Skip Montanaro80072cb2008-12-23 03:51:14 +00001305- Added test case to ensure attempts to read from a file opened for writing
1306 fail.
1307

1312
Antoine Pitrou621601a2008-12-17 23:18:19 +00001313- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1318
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001319- Issue #2173: When getting device encoding, check that return value of
1320 nl_langinfo is not the empty string. This was causing silent build
1321 failures on OS X.
1322
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001323- Issue #4597: Fixed several opcodes that weren't always propagating
1324 exceptions.
1325
1326- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001327 context manager returns a value that cannot be converted to a bool.
1328
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001329- Issue #4445: Replace "sizeof(PyBytesObject)" with
1330 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1331 bytes instances. On a typical machine this saves 3 bytes of memory
1332 (on average) per allocation of a bytes instance.
1333
Christian Heimesa872de52008-12-05 08:26:55 +00001334- Issue #4533: File read operation was dreadfully slow due to a slowly
1335 growing read buffer. Fixed by using the same growth rate algorithm as
1336 Python 2.x.
1337
Antoine Pitrou5504e892008-12-06 21:27:53 +00001338- Issue #4509: Various issues surrounding resize of bytearray objects to
1339 which there are buffer exports (e.g. memoryview instances).
1340
Georg Brandlf9734072008-12-07 15:30:06 +00001341- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1342 method on file objects with closefd=False. The file descriptor is still
1343 kept open but the file object behaves like a closed file. The ``FileIO``
1344 object also got a new readonly attribute ``closefd``.

1352
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001353- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1354 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1355 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1356 of using the replace error handler in PyUnicode_DecodeUTF8().
