315 output compared to previous Python versions.
316
Lars Gustäbel9e2a09a2009-03-22 20:22:29 +0000317- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
318 forever on incomplete input. That caused tarfile.open() to hang when used
319 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
320 partial bzip2 compressed data.
321
Benjamin Peterson373498f2009-03-22 17:49:21 +0000322- Issue #5536: urllib.urlretrieve makes sure to close the file it's writing to

412 do an explicit seek to the end of file (so that e.g. tell() returns the
413 file size rather than 0). This is consistent with the behaviour of the
414 traditional 2.x file object.

449 302 conformant loader) will now work correctly in most cases (they
450 are still subject to the constraints that exist for all code running
451 from inside a module loaded via a PEP 302 loader and attempting to

610What's New in Python 2.6.1
611==========================
612
613*Release date: 04-Dec-2008*
614
615Core and Builtins
616-----------------
617
618- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
619 interpreter to abort ("Fatal Python error: Could not reset the stack!")
620 instead of throwing a MemoryError.
621
622- Issue #4367: Python would segfault during compiling when the unicodedata
623 module couldn't be imported and \N escapes were present.
624
625- Issue #4348: Some bytearray methods returned that didn't cause any change to
626 the bytearray, returned the same bytearray instead of a copy.
627
628- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
629
630- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
631
632- Issue #4048: The parser module now correctly validates relative imports.
633
634- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
635 exec statement.
636
637- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
638 method does not return iterators for the 4th and 5th items.
639
640- Issue #4209: Enabling unicode_literals and the print_function in the same
641 __future__ import didn't work.
642
643- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
644 returned a path longer than MAX_PATH. (But It's doubtful this code path is
645 really executed because I cannot move to such directory on win2k)
646
647- Issue #4069: When set.remove(element) is used with a set element, the element
648 is temporarily replaced with an equivalent frozenset. But the eventual
649 KeyError would always report the empty frozenset([]) as the missing key. Now
650 it correctly refers to the initial element.
651
652- Fixed C99 style comments in several files. Python is now C89 compatible
653 again.
654
655Library

Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000800- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
801
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000802- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
803 PyString_FromFormat or PyErr_Format to display size_t values. The macro
804 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
805 ``printf`` function, whereas PyString_FromFormat has an independent
806 implementation and uses "%zd" on all platforms for size_t values.
807 This makes a difference on win64, where ``printf`` needs "%Id" to display
808 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +0000810- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

814 object; previously an int would be returned for small values. the __long__
815 method is allowed to return either an int or a long, but the behaviour of
816 float objects should not change to respect backward compatibility.

Vinay Sajip35e3b032008-09-01 14:33:59 +0000824 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000825 was correctly parsed but parsing of subsequent arguments failed.
826
Vinay Sajip35e3b032008-09-01 14:33:59 +0000827- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000828 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
829 mechanism. In the process, fix a bug where isinstance() and issubclass(),
830 when given a tuple of classes as second argument, were looking up
831 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
832 type object.

975
Guido van Rossumf8402962008-08-20 15:01:50 +0000976- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
977 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
978 extensions do not automatically benefit from the class attribute
979 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
980 to their tp_flags field if they care. This is a backwards
981 compatibility feature; in 3.0, all types will use the cache by
982 default.

Benjamin Petersonf647dc12008-08-20 01:27:30 +0000984- Keyword arguments can now follow starred arguments. (``f(a, *args,
985 keyword=23)`` is now valid syntax.)
986
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000987- ctypes function pointers that are COM methods have a boolean True
988 value again.

Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000990- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
991 by denying s# to parse objects that have a releasebuffer procedure,
992 and introducing s*.
993
Georg Brandl1e13ea92008-08-11 09:07:59 +0000994- Issue #3537: Fix an assertion failure when an empty but presized dict
995 object was stored in the freelist.
996
Mark Dickinsonb6467572008-08-04 21:30:09 +0000997- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
998 ValueError consistently across platforms.
999
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001000- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1001 (64bit Unix, for example), unichr() would truncate its argument and return
1002 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1003
Neal Norwitze7d8be82008-07-31 17:17:14 +00001004- Apply security patches from Apple.
1005
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001006- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1007 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1008
Antoine Pitrou92f82162008-07-25 22:22:08 +00001009- Issue #1819: function calls with several named parameters are now on
1010 average 35% faster (as measured by pybench).
1011
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001012- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1013 the python debugger steps into a class statement: the free variables (local
1014 variables defined in an outer scope) would be deleted from the outer scope.
1015
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001016- Issue #2620: Overflow checking when allocating or reallocating memory
1017 was not always being done properly in some python types and extension
1018 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1019 all been updated to perform better checks and places in the code that
1020 would previously leak memory on the error path when such an allocation
1021 failed have been fixed.

1027
Benjamin Petersone977ad42008-08-20 01:42:01 +00001028- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1029 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1030
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001031- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1032 version reported by these tools does not necessarily follow the python
1033 version numbering scheme, so the module is less strict when parsing it.
1034
Nick Coghlanf70385a2008-08-18 12:42:46 +00001035- Issue #2235: Added Py3k warnings for types which will become unhashable
1036 under the stricter __hash__ inheritance rules in 3.0. Several types
1037 which did not meet the rules for hash invariants and were already
1038 unhashable in 3.0 have now been explicitly flagged as unhashable in
1039 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1040 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1041
Brett Cannon88f801d2008-08-18 00:46:22 +00001042- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1050
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001051- Issue #3575: Incremental decoder's decode function now takes bytearray
1052 by using 's*' instead of 't#'.
1053
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001054- Issue #2222: Fixed reference leak when occured os.rename()

Facundo Batistaeb90b782008-08-16 14:44:07 +00001063- Issue #2776: fixed small issue when handling an URL with double slash
1064 after a 302 response in the case of not going through a proxy.
1065
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001066- Issue #2676: in the email package, content-type parsing was hanging on
1067 pathological input because of quadratic or exponential behaviour of a
1068 regular expression.
1069
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001070- Issue #3476: binary buffered reading through the new "io" library is now
1071 thread-safe.
1072
Brett Cannonbf3157b2008-08-14 05:00:03 +00001073- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1074 since mimetools itself is deprecated. Because modules are cached, all
1075 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1076
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001077- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00001079- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1080 menu entries were not deleted.
1081
Brett Cannon83e81842008-08-09 23:30:55 +00001082- Copied the implementation of reduce() to _functools.reduce() to have a
1083 version that did not raise a DeprecationWarning under -3.
1084
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001085- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1086 a MemoryError rather than silently stop the iteration.
1087
Guido van Rossum59ce9012008-08-09 14:55:34 +00001088- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1089 to _sre.compile() will now be rejected. This should not affect anybody
1090 since the re.compile() function never generates invalid re-bytecode.
1091
Skip Montanaroa032bf42008-08-08 22:52:51 +00001092- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1093 upon first access it can be automatically initialized from the csv file if
1094 it wasn't initialized during instantiation.
1095
Brett Cannon3aa2a492008-08-06 22:28:09 +00001096- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1097 the reload() built-in has been removed.
1098
Brett Cannon7e30b672008-08-04 21:52:25 +00001099- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001100 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1108 raised an AttributeError.
1109
Benjamin Peterson01a24322008-07-28 23:35:27 +00001110- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001111 asking for a specific length. This problem only affected files opened
1112 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001113

1136
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001137- Issue #3394: zipfile.writestr sets external attributes when passed a
1138 file name rather than a ZipInfo instance, so files are extracted with
1139 mode 0600 rather than 000 under Unix.
1140
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001141- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1142 argument in python 2.5, this broke code that subclassed Popen to include its
1143 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001153- Issue #2235: the C API function PyObject_HashNotImplemented and its
1154 interaction with the tp_hash slot (added in 2.6b2) are now documented
1155
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001156- Issue #643841: The language reference now provides more detailed
1157 coverage of the lookup process for special methods. The disclaimers
1158 regarding lack of coverage of new-style classes have also been
1159 removed, since the coverage is now fairly reasonable.

1163================================
1164
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001165*Release date: 17-Jul-2008*
1166
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001167Core and Builtins
1168-----------------
1169
Georg Brandl3e483f62008-07-16 22:57:41 +00001170- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1171 its methods now allow for items objects that can be converted to
1172 an integer using operator.index().
1173
Mark Dickinson64b7e502008-07-16 09:40:03 +00001174- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1175 produced a ValueError instead of giving the correct float.
1176
Eric Smitha5fa5a22008-07-16 00:11:49 +00001177- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1178 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1179
Mark Dickinson7103aa42008-07-15 19:08:33 +00001180- Issue #3008: the float type has a new instance method 'float.hex'
1181 and a new class method 'float.fromhex' to convert floating-point
1182 numbers to and from hexadecimal strings, respectively.
1183
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001184- Issue #2235: __hash__ is once again inherited by default. To allow
1185 collections.Hashable to remain meaningful in the presence of the
1186 default hash implementation (object.__hash__), it is now possible
1187 to explicit block inheritance of hash by setting __hash__=None at
1188 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1189 level.
1190
Nick Coghlanb028f502008-07-13 14:52:36 +00001191- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1192 the parent module cannot be found while performing an absolute import.
1193 This means that an incorrectly defined __package__ attribute will
1194 now only prevent relative imports in that module rather than causing
1195 all imports from that module to fail.
1196
Nick Coghlan14ff9942008-07-08 14:21:42 +00001197- Issue #2517: Allow unicode messages in Exceptions again by correctly
1198 bypassing the instance dictionary when looking up __unicode__ on
1199 new-style classes.
1200
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001201- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1202 set to a custom object whose write() method happens to install
1203 another file in sys.stdout.
1204
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001205- Issue #3088: Corrected a race condition in classes derived from
1206 threading.local: the first member set by a thread could be saved in
1207 another thread's dictionary.
1208
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001209- Issue #3004: Minor change to slice.indices(): the start and stop
1210 arguments are now treated identically, making the behaviour easier
1211 to describe and understand. For example, slice(None, -10,
1212 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1213 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1214 10, -1).
1215
Georg Brandl278fc502008-07-19 12:46:12 +00001216- Issue #3219: Calling a function with repeated keyword arguments,
1217 f(a=2, a=23), would not cause a syntax error. This was a regression
1218 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001219
Georg Brandl278fc502008-07-19 12:46:12 +00001220- Issue #2862: Make int and float freelist management consistent with
1221 other freelists. Changes their CompactFreeList apis into
1222 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001223

1226
Thomas Heller57adf222008-08-14 19:10:48 +00001227- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1228 api functions without holding the GIL, which could lead to a fatal
1229 error when they failed.
1230
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001231- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1245 a valid dlerror() message.
1246
Thomas Heller2bad6572008-07-15 17:19:50 +00001247- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1248 incomplete structure was created.
1249
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001250- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00001252- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1253
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001254- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001255
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001256- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1257 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001258 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001259 content-length. The problem had been corrected in the 2.4 branch, but never
1260 merged into trunk.
1261
Georg Brandle78fbcc2008-07-05 10:13:36 +00001262- Issue #2663: add filtering capability to shutil.copytree().

1667 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001668 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001669
1670 This is controlled by the configure argument ``--with-universal-archs``:
1671
1672 - ``--with-universal-archs=all``: install 4-way universal
1673
1674 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1675
1676 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1677
1678 This option should be used in combination with ``--enable-universalsdk=``.
1679
1680 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00001730- Issue #1631171: Re-implement the 'warnings' module in C (the
1731 original Python code has been kept as backup). This will allow for
1732 using the 'warning's machinery in such places as the parser where
1733 use of pure Python code is not possible. Both the ``showarning()``
1734 and ``formatwarning()`` gain an optional 'line' argument which is
1735 not called by default for backwards-compatibility reasons. Setting
1736 ``warnings.showwarning()`` to an implementation that lacks support
1737 for the ``line`` argument will raise a DeprecationWarning.

1761
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001762- The getpass module has been improved on Unix. It now uses /dev/tty
1763 by default and uses stderr instead of stdout. A GetPassWarning is
1764 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001800- Issue #2550: The approach used by client/server code for obtaining
1801 ports to listen on in network-oriented tests has been refined in an
1802 effort to facilitate running multiple instances of the entire
1803 regression test suite in parallel without issue.
1804 test_support.bind_port() has been fixed such that it will always
1805 return a unique port -- which wasn't always the case with the
1806 previous implementation, especially if socket options had been set
1807 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1808 new implementation of bind_port() will actually raise an exception
1809 if it is passed an AF_INET/SOCK_STREAM socket with either the
1810 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1811 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1812 the socket it's been passed. This currently only applies to
1813 Windows. This option prevents any other sockets from binding to the
1814 host/port we've bound to, thus removing the possibility of the
1815 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1816 when a second SOCK_STREAM socket binds and accepts to a host/port
1817 that's already been bound by another socket. The optional preferred
1818 port parameter to bind_port() has been removed. Under no
1819 circumstances should tests be hard coding ports!
1820
1821 test_support.find_unused_port() has also been introduced, which will
1822 pass a temporary socket object to bind_port() in order to obtain an
1823 unused port. The temporary socket object is then closed and
1824 deleted, and the port is returned. This method should only be used
1825 for obtaining an unused port in order to pass to an external program
1826 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1827 a parameter to a server-oriented class that doesn't give you direct
1828 access to the underlying socket used.
1829
1830 Finally, test_support.HOST has been introduced, which should be used
1831 for the host argument of any relevant socket calls (i.e. bind and
1832 connect).

2106Core and builtins
2107-----------------
2108
Fred Drakea8ee94b2008-03-01 02:45:07 +00002109- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002110 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002111
Georg Brandlad61bc82008-02-23 15:11:18 +00002112- Issue #2067: file.__exit__() now calls subclasses' close() method.
2113
2114- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002115
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002116- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002117 issue 215555 for a discussion.
2118
Eric Smitha73fbe72008-02-23 03:09:44 +00002119- Added the future_builtins module, which contains hex() and oct().
2120 These are the PEP 3127 version of these functions, designed to be
2121 compatible with the hex() and oct() builtins from Python 3.0. They
2122 differ slightly in their output formats from the existing, unchanged
2123 Python 2.6 builtins. The expected usage of the future_builtins
2124 module is:
2125 from future_builtins import hex, oct
2126
Eric Smith7ef40bf2008-02-20 23:34:22 +00002127- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2128 exponents for exponents with absolute value < 100. Follows C99
2129 standard. This is a change on Windows, which would use 3 digits.
2130 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2131 so that any alterations it does to the resulting string will be
2132 available in stringlib/formatter.h (for float.__format__).
2133
Eric Smith5a3c1352008-02-19 13:21:56 +00002134- Implemented PEP 3101, Advanced String Formatting. This adds a new
2135 builtin format(); a format() method for str and unicode; a
2136 __format__() method to object, str, unicode, int, long, float, and
2137 datetime; the class string.Formatter; and the C API
2138 PyObject_Format().
2139
Georg Brandl3ee81df2008-05-17 18:14:43 +00002140- Fixed several potential crashes, all caused by specially crafted
2141 __del__ methods exploiting objects in temporarily inconsistent
2142 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002143
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002144- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002145 prevent a possible crash: an Abstract Base Class would try to access
2146 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002147
Georg Brandl3ee81df2008-05-17 18:14:43 +00002148- Fixed repr() and str() of complex numbers with infinity or nan as
2149 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002150
Georg Brandl3ee81df2008-05-17 18:14:43 +00002151- Clear all free lists during a gc.collect() of the highest generation
2152 in order to allow pymalloc to free more arenas. Python may give back
2153 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002154
Georg Brandl3ee81df2008-05-17 18:14:43 +00002155- Issue #2045: Fix an infinite recursion triggered when printing a
2156 subclass of collections.defaultdict, if its default_factory is set
2157 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002158
Christian Heimesf75dbef2008-02-08 00:11:31 +00002159- Fixed a minor memory leak in dictobject.c. The content of the free
2160 list was not freed on interpreter shutdown.
2161
Georg Brandl3ee81df2008-05-17 18:14:43 +00002162- Limit free list of method and builtin function objects to 256
2163 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002164
Georg Brandl3ee81df2008-05-17 18:14:43 +00002165- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2166 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002167 to compact the internal free lists of pre-allocted ints and floats.
2168
Georg Brandl3ee81df2008-05-17 18:14:43 +00002169- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2170 calls. Python expected the return type int but the fork familie
2171 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002172
Georg Brandl3ee81df2008-05-17 18:14:43 +00002173- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2174 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002175
Georg Brandl3ee81df2008-05-17 18:14:43 +00002176- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2177 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002178
Georg Brandl3ee81df2008-05-17 18:14:43 +00002179- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2180 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002181
Georg Brandl3ee81df2008-05-17 18:14:43 +00002182- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2183 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002184
Georg Brandl3ee81df2008-05-17 18:14:43 +00002185- Patch #1473257: generator objects gain a gi_code attribute. This is
2186 the same object as the func_code attribute of the function that
2187 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002188
Georg Brandl3ee81df2008-05-17 18:14:43 +00002189- Issue #1920: "while 0" statements were completely removed by the
2190 compiler, even in the presence of an "else" clause, which is
2191 supposed to be run when the condition is false. Now the compiler
2192 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002193
Guido van Rossumeead05f2008-01-24 18:21:02 +00002194- A few crashers fixed: weakref_in_del.py (issue #1377858);
2195 loosing_dict_ref.py (issue #1303614, test67.py);
2196 borrowed_ref_[34].py (not in tracker).
2197
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002198- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002199 suppressed while an extension is loaded by calling SetErrorMode in
2200 dynload_win.c. The error is still reported properly.
2201
Georg Brandl3ee81df2008-05-17 18:14:43 +00002202- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002203 several extension methods and modules do not work without unicode
2204 support.
2205
Georg Brandl26543b12008-01-21 18:36:51 +00002206- Issue #1882: when compiling code from a string, encoding cookies in the
2207 second line of code were not always recognized correctly.
2208
Georg Brandl14404b62008-01-19 19:27:05 +00002209- Issue #1679: "0x" was taken as a valid integer literal.
2210
Georg Brandl6caad7d2008-01-26 14:19:22 +00002211- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002212 added.
2213
Christian Heimesc94e2b52008-01-14 04:13:37 +00002214- sys.float_info / PyFloat_GetInfo: The floating point information
2215 object was converted from a dict to a specialized structseq object.
2216
Georg Brandl3ee81df2008-05-17 18:14:43 +00002217- Patch #1816: Added sys.flags structseq. It exposes the status of
2218 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002219
Georg Brandl3ee81df2008-05-17 18:14:43 +00002220- Objects/structseq.c: Implemented new structseq representation. The
2221 patch makes structseqs (e.g. the return value of os.stat) more
2222 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002223
Georg Brandl3ee81df2008-05-17 18:14:43 +00002224- Patch #1700288: added a type attribute cache that caches method
2225 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002226
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002227- Bug #1776: __import__() no longer accepts filenames on any platform.
2228 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002229
Georg Brandlaed6c662008-01-07 17:25:53 +00002230- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2231
Georg Brandl3ee81df2008-05-17 18:14:43 +00002232- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2233 envvar and sys.dont_write_bytecode attribute. All these can be set
2234 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002235
Georg Brandl3ee81df2008-05-17 18:14:43 +00002236- Improve some exception messages when Windows fails to load an
2237 extension module. Now we get for example '%1 is not a valid Win32
2238 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002239
Georg Brandl3ee81df2008-05-17 18:14:43 +00002240- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002242- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2243 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002244
Christian Heimes0a8143f2007-12-18 23:22:54 +00002245- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002246 and INF. float("nan"), float("inf") and float("-inf") now work on
2247 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002248
Georg Brandl3ee81df2008-05-17 18:14:43 +00002249- Compiler now generates simpler and faster code for dictionary
2250 literals. The oparg for BUILD_MAP now indicates an estimated
2251 dictionary size. There is a new opcode, STORE_MAP, for adding
2252 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002253
Georg Brandl3ee81df2008-05-17 18:14:43 +00002254- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002262- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002263 SystemError.
2264
Nick Coghlanef01d822007-12-03 12:55:17 +00002265- PEP 366: Allow explicit relative imports when executing modules
2266 inside packages with the -m switch via a new module level
2267 __package__ attribute.
2268
Georg Brandl3ee81df2008-05-17 18:14:43 +00002269- Issue #1402: Fix a crash on exit, when another thread is still
2270 running, and if the deallocation of its frames somehow calls the
2271 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002272

2282 file can now be directly executed by passing their name to the
2283 interpreter. The directory/zipfile is automatically inserted as the
2284 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002285
Georg Brandl3ee81df2008-05-17 18:14:43 +00002286- Issue #1265: Fix a problem with sys.settrace, if the tracing
2287 function uses a generator expression when at the same time the
2288 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002289
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002290- sets and frozensets now have an isdisjoint() method.
2291
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002292- optimize the performance of builtin.sum().
2293
Neal Norwitz44f326e2007-10-05 05:29:17 +00002294- Fix warnings found by the new version of the Coverity checker.
2295
Georg Brandl3ee81df2008-05-17 18:14:43 +00002296- The enumerate() builtin function is no longer bounded to sequences
2297 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2298 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002299
Georg Brandl3ee81df2008-05-17 18:14:43 +00002300- Issue #1686386: Tuple's tp_repr did not take into account the
2301 possibility of having a self-referential tuple, which is possible
2302 from C code. Nor did object's tp_str consider that a type's tp_str
2303 could do something that could lead to an inifinite recursion.
2304 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2305 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002306
Georg Brandl3ee81df2008-05-17 18:14:43 +00002307- Issue #1164: It was possible to trigger deadlock when using the
2308 'print' statement to write to a file since the GIL was not released
2309 as needed. Now PyObject_Print() does the right thing along with
2310 various tp_print implementations of the built-in types and those in
2311 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002313- Issue #1147: Exceptions were directly allowing string exceptions in
2314 their throw() method even though string exceptions no longer
2315 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002316
Georg Brandl3ee81df2008-05-17 18:14:43 +00002317- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002320- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002321 PyObject_Call() never calling back out to Python code to trigger
2322 recursion depth updates/checks. Required the creation of a static
2323 RuntimeError instance in case normalizing an exception put the
2324 recursion check value past its limit. Fixes crashers
2325 infinite_rec_(1|2|4|5).py.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002341 __*__ attributes. (Some already existed, e.g., __doc__ and
2342 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002343

Georg Brandl3ee81df2008-05-17 18:14:43 +00002351 "except E as target:". This is to provide forwards compatibility
2352 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002353
Brett Cannon229cee22007-05-05 01:34:02 +00002354- Deprecate BaseException.message as per PEP 352.

2372
Guido van Rossum143b5642007-03-23 04:58:42 +00002373- Bug #1683368: The object.__init__() and object.__new__() methods are
2374 now stricter in rejecting excess arguments. The only time when
2375 either allows excess arguments is when it is not overridden and the
2376 other one is. For backwards compatibility, when both are
2377 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002378 warning later). Also, type.__init__() insists on the same signature
2379 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002380
Georg Brandl3ee81df2008-05-17 18:14:43 +00002381- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2382 object to complex using its __complex__() method before falling back
2383 to the __float__() method. Therefore, the functions in the cmath
2384 module now can operate on objects that define a __complex__()
2385 method.

2402
Georg Brandl7b9c5552007-03-12 14:30:05 +00002403- Bug #1678647: write a newline after printing an exception in any
2404 case, even when converting the value to a string failed.
2405
Georg Brandl871f1bc2007-03-12 13:17:36 +00002406- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002407 its argument, if it exists. If not, it will work like before. This
2408 allows customizing the output of dir() in the presence of a
2409 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002410
Collin Winter276887b2007-03-12 16:11:39 +00002411- Patch #922167: Python no longer segfaults when faced with infinitely
2412 self-recursive reload() calls (as reported by bug #742342).

2419 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002420
Georg Brandlaa2321b2007-03-07 00:40:28 +00002421- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002422 makes the filenames the warning module prints much more sensible
2423 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002424

Georg Brandl0fca97a2007-03-05 22:28:08 +00002436- Patch #1674228: when assigning a slice (old-style), check for the
2437 sq_ass_slice instead of the sq_slice slot.
2438
Georg Brandl3ee81df2008-05-17 18:14:43 +00002439- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00003065- unittest now verifies more of its assumptions. In particular,
3066 TestCase and TestSuite subclasses (not instances) are no longer
3067 accepted in TestSuite.addTest(). This should cause no
3068 incompatibility since it never made sense with ordinary subclasses
3069 -- the failure just occurred later, with a more cumbersome
3070 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003351- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3352 with RFC 3207 and forgets any knowledge obtained from the server not
3353 obtained from the TLS negotiation itself. Patch contributed by Bill
3354 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003355
Georg Brandl3ee81df2008-05-17 18:14:43 +00003356- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003357 that the SMTP.starttls() caller no longer needs to call ehlo()
3358 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003359 does not claim to support starttls. Adds the
3360 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3441 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3442 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003459 time so that opening a database previously created with the DB_DUP
3460 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3461 opens. Specifically: dictionary assignment to a DB object will
3462 replace all values for a given key when the database allows
3463 duplicate values. DB users should use DB.put(k, v) when they want
3464 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003465

3471 characters with ASCII value less than 32. Also, it correctly quotes
3472 dots only if they occur on a single line, as opposed to the previous
3473 behavior of quoting dots if they are the second character of any
3474 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003475

Georg Brandl3ee81df2008-05-17 18:14:43 +00003804- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3805 to ``PyTuple_SetItem``, it can be used to populate a brand new
3806 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00003807
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003808- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003810- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
3811 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
3812 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003813
3814- Patch #1720595: add T_BOOL to the range of structmember types.
3815
3816- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
3817 ``PyFloat_GetInfo()`` to the float API.
3818
Georg Brandl3ee81df2008-05-17 18:14:43 +00003819- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3820 of w# format code incorrectly truncated the length to an int, even
3821 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3822 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003823
Georg Brandl3ee81df2008-05-17 18:14:43 +00003824- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
3825 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003826
Georg Brandl3ee81df2008-05-17 18:14:43 +00003827- PEP 3123: Provide forward compatibility with Python 3.0, while
3828 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
3829 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003830
Georg Brandl3ee81df2008-05-17 18:14:43 +00003831- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
3832 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003833
3834- Patch #1733960: Allow T_LONGLONG to accept ints.
3835
3836- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
3837
Christian Heimes000a0742008-01-03 22:16:32 +00003838- Added a new API function ``PyImport_ImportModuleNoBlock``.
3839
Georg Brandl6caad7d2008-01-26 14:19:22 +00003840- Bug #1637022: Prefix AST symbols with _Py_.
3841
3842- Fix some leftovers from the conversion from int to Py_ssize_t
3843 (relevant to strings and sequences of more than 2**31 items).
3844
3845- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3846 outside of pystate.c and should not be necessary.
3847
Georg Brandl3ee81df2008-05-17 18:14:43 +00003848- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3849 absolute imports. In earlier versions they might have used relative
3850 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003851
Georg Brandl3ee81df2008-05-17 18:14:43 +00003852- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3853 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003854
Georg Brandl3ee81df2008-05-17 18:14:43 +00003855- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
3856 macro so it can be used as an expression.

3861
Georg Brandl3ee81df2008-05-17 18:14:43 +00003862- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3863 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3864 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3865 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003866
Georg Brandl3ee81df2008-05-17 18:14:43 +00003867- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
3868 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00003878- buildtools now raises a DeprecationWarning.
3879
Georg Brandl3ee81df2008-05-17 18:14:43 +00003880- Removed the macfs module. It had been deprecated since Python 2.5.
3881 This lead to the deprecation of macostools.touched() as it relied
3882 solely on macfs and was a no-op under OS X.
