363 do an explicit seek to the end of file (so that e.g. tell() returns the

365 traditional 2.x file object.

400 302 conformant loader) will now work correctly in most cases (they
401 are still subject to the constraints that exist for all code running

561What's New in Python 2.6.1
562==========================
563
564*Release date: 04-Dec-2008*
565
566Core and Builtins
567-----------------
568
569- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
570 interpreter to abort ("Fatal Python error: Could not reset the stack!")
571 instead of throwing a MemoryError.
572
573- Issue #4367: Python would segfault during compiling when the unicodedata
574 module couldn't be imported and \N escapes were present.
575
576- Issue #4348: Some bytearray methods returned that didn't cause any change to
577 the bytearray, returned the same bytearray instead of a copy.
578
579- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
580
581- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
582
583- Issue #4048: The parser module now correctly validates relative imports.
584
585- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
586 exec statement.
587
588- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
589 method does not return iterators for the 4th and 5th items.
590
591- Issue #4209: Enabling unicode_literals and the print_function in the same
592 __future__ import didn't work.
593
594- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
595 returned a path longer than MAX_PATH. (But It's doubtful this code path is
596 really executed because I cannot move to such directory on win2k)
597
598- Issue #4069: When set.remove(element) is used with a set element, the element
599 is temporarily replaced with an equivalent frozenset. But the eventual
600 KeyError would always report the empty frozenset([]) as the missing key. Now
601 it correctly refers to the initial element.
602
603- Fixed C99 style comments in several files. Python is now C89 compatible
604 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000751- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
752
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000753- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
754 PyString_FromFormat or PyErr_Format to display size_t values. The macro
755 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
756 ``printf`` function, whereas PyString_FromFormat has an independent
757 implementation and uses "%zd" on all platforms for size_t values.
758 This makes a difference on win64, where ``printf`` needs "%Id" to display
759 64bit values.
760
Benjamin Peterson97179b02008-09-09 20:55:01 +0000761- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
762 error.
763
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +0000764- Issue #3777: long() applied to a float object now always return a long
765 object; previously an int would be returned for small values. the __long__
766 method is allowed to return either an int or a long, but the behaviour of
767 float objects should not change to respect backward compatibility.
768
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000769- Issue #3751: str.rpartition would perform a left-partition when called with
770 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +0000775 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000776 was correctly parsed but parsing of subsequent arguments failed.
777
Vinay Sajip35e3b032008-09-01 14:33:59 +0000778- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000779 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
780 mechanism. In the process, fix a bug where isinstance() and issubclass(),
781 when given a tuple of classes as second argument, were looking up
782 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
783 type object.
784

854 warnings.catch_warnings() along with some API cleanup. Expanding the tests
855 for catch_warnings() also led to an improvement in the raising of a
856 DeprecationWarning related to warnings.warn_explicit().

924Core and Builtins
925-----------------
926
Guido van Rossumf8402962008-08-20 15:01:50 +0000927- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
928 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
929 extensions do not automatically benefit from the class attribute
930 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
931 to their tp_flags field if they care. This is a backwards
932 compatibility feature; in 3.0, all types will use the cache by
933 default.
934
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000935- Keyword arguments can now follow starred arguments. (``f(a, *args,
936 keyword=23)`` is now valid syntax.)
937
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000938- ctypes function pointers that are COM methods have a boolean True
939 value again.
940
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000941- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
942 by denying s# to parse objects that have a releasebuffer procedure,
943 and introducing s*.
944
Georg Brandl1e13ea92008-08-11 09:07:59 +0000945- Issue #3537: Fix an assertion failure when an empty but presized dict
946 object was stored in the freelist.
947
Mark Dickinsonb6467572008-08-04 21:30:09 +0000948- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
949 ValueError consistently across platforms.
950
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000951- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
952 (64bit Unix, for example), unichr() would truncate its argument and return
953 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
954
Neal Norwitze7d8be82008-07-31 17:17:14 +0000955- Apply security patches from Apple.
956
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000957- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
958 PyErr_ExceptionMatches returns 0 when an exception occurs there.
959
Antoine Pitrou92f82162008-07-25 22:22:08 +0000960- Issue #1819: function calls with several named parameters are now on
961 average 35% faster (as measured by pybench).
962
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000963- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
964 the python debugger steps into a class statement: the free variables (local
965 variables defined in an outer scope) would be deleted from the outer scope.
966
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000967- Issue #2620: Overflow checking when allocating or reallocating memory
968 was not always being done properly in some python types and extension
969 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
970 all been updated to perform better checks and places in the code that
971 would previously leak memory on the error path when such an allocation
972 failed have been fixed.

Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000982- Issue #2234: distutils failed for some versions of the cygwin compiler. The
983 version reported by these tools does not necessarily follow the python
984 version numbering scheme, so the module is less strict when parsing it.
985
Nick Coghlanf70385a2008-08-18 12:42:46 +0000986- Issue #2235: Added Py3k warnings for types which will become unhashable
987 under the stricter __hash__ inheritance rules in 3.0. Several types
988 which did not meet the rules for hash invariants and were already
989 unhashable in 3.0 have now been explicitly flagged as unhashable in
990 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
991 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
992
Brett Cannon88f801d2008-08-18 00:46:22 +0000993- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1019 regular expression.
1020

1022 thread-safe.
1023
Brett Cannonbf3157b2008-08-14 05:00:03 +00001024- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1025 since mimetools itself is deprecated. Because modules are cached, all
1026 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1027

1040 to _sre.compile() will now be rejected. This should not affect anybody
1041 since the re.compile() function never generates invalid re-bytecode.
1042
Skip Montanaroa032bf42008-08-08 22:52:51 +00001043- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1044 upon first access it can be automatically initialized from the csv file if
1045 it wasn't initialized during instantiation.
1046
Brett Cannon3aa2a492008-08-06 22:28:09 +00001047- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1048 the reload() built-in has been removed.
1049
Brett Cannon7e30b672008-08-04 21:52:25 +00001050- Changed code in the following modules/packages to remove warnings raised

1059 raised an AttributeError.
1060
Benjamin Peterson01a24322008-07-28 23:35:27 +00001061- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001062 asking for a specific length. This problem only affected files opened
1063 using the new "io" module, not the built-in open() function.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001088- Issue #3394: zipfile.writestr sets external attributes when passed a
1089 file name rather than a ZipInfo instance, so files are extracted with
1090 mode 0600 rather than 000 under Unix.
1091
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001092- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001104- Issue #2235: the C API function PyObject_HashNotImplemented and its
1105 interaction with the tp_hash slot (added in 2.6b2) are now documented
1106
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001107- Issue #643841: The language reference now provides more detailed
1108 coverage of the lookup process for special methods. The disclaimers
1109 regarding lack of coverage of new-style classes have also been
1110 removed, since the coverage is now fairly reasonable.

1114================================
1115
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001116*Release date: 17-Jul-2008*
1117
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001118Core and Builtins
1119-----------------
1120
Georg Brandl3e483f62008-07-16 22:57:41 +00001121- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1122 its methods now allow for items objects that can be converted to
1123 an integer using operator.index().
1124
Mark Dickinson64b7e502008-07-16 09:40:03 +00001125- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1126 produced a ValueError instead of giving the correct float.
1127
Eric Smitha5fa5a22008-07-16 00:11:49 +00001128- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1129 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1130
Mark Dickinson7103aa42008-07-15 19:08:33 +00001131- Issue #3008: the float type has a new instance method 'float.hex'
1132 and a new class method 'float.fromhex' to convert floating-point
1133 numbers to and from hexadecimal strings, respectively.
1134
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001135- Issue #2235: __hash__ is once again inherited by default. To allow
1136 collections.Hashable to remain meaningful in the presence of the
1137 default hash implementation (object.__hash__), it is now possible
1138 to explicit block inheritance of hash by setting __hash__=None at
1139 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1140 level.
1141
Nick Coghlanb028f502008-07-13 14:52:36 +00001142- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1143 the parent module cannot be found while performing an absolute import.
1144 This means that an incorrectly defined __package__ attribute will
1145 now only prevent relative imports in that module rather than causing
1146 all imports from that module to fail.
1147
Nick Coghlan14ff9942008-07-08 14:21:42 +00001148- Issue #2517: Allow unicode messages in Exceptions again by correctly
1149 bypassing the instance dictionary when looking up __unicode__ on
1150 new-style classes.
1151
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001152- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1153 set to a custom object whose write() method happens to install
1154 another file in sys.stdout.
1155
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001156- Issue #3088: Corrected a race condition in classes derived from
1157 threading.local: the first member set by a thread could be saved in
1158 another thread's dictionary.
1159
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001160- Issue #3004: Minor change to slice.indices(): the start and stop
1161 arguments are now treated identically, making the behaviour easier
1162 to describe and understand. For example, slice(None, -10,
1163 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1164 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1165 10, -1).
1166
Georg Brandl278fc502008-07-19 12:46:12 +00001167- Issue #3219: Calling a function with repeated keyword arguments,
1168 f(a=2, a=23), would not cause a syntax error. This was a regression
1169 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001170
Georg Brandl278fc502008-07-19 12:46:12 +00001171- Issue #2862: Make int and float freelist management consistent with
1172 other freelists. Changes their CompactFreeList apis into
1173 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00001178- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1179 api functions without holding the GIL, which could lead to a fatal
1180 error when they failed.
1181
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001182- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Vinay Sajip51e65192008-07-18 09:01:10 +00001193- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001207- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1208 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001209 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001210 content-length. The problem had been corrected in the 2.4 branch, but never
1211 merged into trunk.
1212

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001226- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1227 handling is now the same as that of other special attributes like __name__).
1228
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001229- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

1618 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001619 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001620
1621 This is controlled by the configure argument ``--with-universal-archs``:
1622
1623 - ``--with-universal-archs=all``: install 4-way universal
1624
1625 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1626
1627 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1628
1629 This option should be used in combination with ``--enable-universalsdk=``.
1630
1631 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 +00001681- Issue #1631171: Re-implement the 'warnings' module in C (the
1682 original Python code has been kept as backup). This will allow for
1683 using the 'warning's machinery in such places as the parser where
1684 use of pure Python code is not possible. Both the ``showarning()``
1685 and ``formatwarning()`` gain an optional 'line' argument which is
1686 not called by default for backwards-compatibility reasons. Setting
1687 ``warnings.showwarning()`` to an implementation that lacks support
1688 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001751- Issue #2550: The approach used by client/server code for obtaining
1752 ports to listen on in network-oriented tests has been refined in an
1753 effort to facilitate running multiple instances of the entire
1754 regression test suite in parallel without issue.
1755 test_support.bind_port() has been fixed such that it will always
1756 return a unique port -- which wasn't always the case with the
1757 previous implementation, especially if socket options had been set
1758 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1759 new implementation of bind_port() will actually raise an exception
1760 if it is passed an AF_INET/SOCK_STREAM socket with either the
1761 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1762 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1763 the socket it's been passed. This currently only applies to
1764 Windows. This option prevents any other sockets from binding to the
1765 host/port we've bound to, thus removing the possibility of the
1766 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1767 when a second SOCK_STREAM socket binds and accepts to a host/port
1768 that's already been bound by another socket. The optional preferred
1769 port parameter to bind_port() has been removed. Under no
1770 circumstances should tests be hard coding ports!
1771
1772 test_support.find_unused_port() has also been introduced, which will
1773 pass a temporary socket object to bind_port() in order to obtain an
1774 unused port. The temporary socket object is then closed and
1775 deleted, and the port is returned. This method should only be used
1776 for obtaining an unused port in order to pass to an external program
1777 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1778 a parameter to a server-oriented class that doesn't give you direct
1779 access to the underlying socket used.
1780
1781 Finally, test_support.HOST has been introduced, which should be used
1782 for the host argument of any relevant socket calls (i.e. bind and
1783 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001784
1785 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001786 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001787 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1788 test_asynchat and test_socket_ssl.
1789
Georg Brandl3ee81df2008-05-17 18:14:43 +00001790 It is now possible for multiple instances of the regression test
1791 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00001845- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00001846 \Uxxxxxxxx did not accept values outside the Basic Multilingual
1847 Plane. This affected raw unicode literals and the
1848 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
1849 this case, like normal unicode literals and the 'unicode-escape'
1850 codec.

2059

2069
Eric Smitha73fbe72008-02-23 03:09:44 +00002070- Added the future_builtins module, which contains hex() and oct().
2071 These are the PEP 3127 version of these functions, designed to be
2072 compatible with the hex() and oct() builtins from Python 3.0. They
2073 differ slightly in their output formats from the existing, unchanged
2074 Python 2.6 builtins. The expected usage of the future_builtins
2075 module is:

2077
Eric Smith7ef40bf2008-02-20 23:34:22 +00002078- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2079 exponents for exponents with absolute value < 100. Follows C99
2080 standard. This is a change on Windows, which would use 3 digits.
2081 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2082 so that any alterations it does to the resulting string will be
2083 available in stringlib/formatter.h (for float.__format__).
2084
Eric Smith5a3c1352008-02-19 13:21:56 +00002085- Implemented PEP 3101, Advanced String Formatting. This adds a new
2086 builtin format(); a format() method for str and unicode; a
2087 __format__() method to object, str, unicode, int, long, float, and
2088 datetime; the class string.Formatter; and the C API
2089 PyObject_Format().
2090
Georg Brandl3ee81df2008-05-17 18:14:43 +00002091- Fixed several potential crashes, all caused by specially crafted
2092 __del__ methods exploiting objects in temporarily inconsistent
2093 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002094
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002095- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002096 prevent a possible crash: an Abstract Base Class would try to access
2097 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002098

Georg Brandl3ee81df2008-05-17 18:14:43 +00002102- Clear all free lists during a gc.collect() of the highest generation
2103 in order to allow pymalloc to free more arenas. Python may give back
2104 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002105
Georg Brandl3ee81df2008-05-17 18:14:43 +00002106- Issue #2045: Fix an infinite recursion triggered when printing a
2107 subclass of collections.defaultdict, if its default_factory is set
2108 to a bound method.

Christian Heimesf75dbef2008-02-08 00:11:31 +00002110- Fixed a minor memory leak in dictobject.c. The content of the free
2111 list was not freed on interpreter shutdown.
2112
Georg Brandl3ee81df2008-05-17 18:14:43 +00002113- Limit free list of method and builtin function objects to 256
2114 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002115
Georg Brandl3ee81df2008-05-17 18:14:43 +00002116- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2117 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002118 to compact the internal free lists of pre-allocted ints and floats.
2119
Georg Brandl3ee81df2008-05-17 18:14:43 +00002120- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2121 calls. Python expected the return type int but the fork familie
2122 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002123
Georg Brandl3ee81df2008-05-17 18:14:43 +00002124- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2125 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002136- Patch #1473257: generator objects gain a gi_code attribute. This is
2137 the same object as the func_code attribute of the function that
2138 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002139
Georg Brandl3ee81df2008-05-17 18:14:43 +00002140- Issue #1920: "while 0" statements were completely removed by the
2141 compiler, even in the presence of an "else" clause, which is
2142 supposed to be run when the condition is false. Now the compiler
2143 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002144
Guido van Rossumeead05f2008-01-24 18:21:02 +00002145- A few crashers fixed: weakref_in_del.py (issue #1377858);
2146 loosing_dict_ref.py (issue #1303614, test67.py);
2147 borrowed_ref_[34].py (not in tracker).
2148
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002149- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002150 suppressed while an extension is loaded by calling SetErrorMode in
2151 dynload_win.c. The error is still reported properly.
2152
Georg Brandl3ee81df2008-05-17 18:14:43 +00002153- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002154 several extension methods and modules do not work without unicode
2155 support.
2156
Georg Brandl26543b12008-01-21 18:36:51 +00002157- Issue #1882: when compiling code from a string, encoding cookies in the
2158 second line of code were not always recognized correctly.
2159
Georg Brandl14404b62008-01-19 19:27:05 +00002160- Issue #1679: "0x" was taken as a valid integer literal.
2161
Georg Brandl6caad7d2008-01-26 14:19:22 +00002162- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002163 added.
2164
Christian Heimesc94e2b52008-01-14 04:13:37 +00002165- sys.float_info / PyFloat_GetInfo: The floating point information
2166 object was converted from a dict to a specialized structseq object.
2167
Georg Brandl3ee81df2008-05-17 18:14:43 +00002168- Patch #1816: Added sys.flags structseq. It exposes the status of
2169 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002170
Georg Brandl3ee81df2008-05-17 18:14:43 +00002171- Objects/structseq.c: Implemented new structseq representation. The
2172 patch makes structseqs (e.g. the return value of os.stat) more
2173 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002174
Georg Brandl3ee81df2008-05-17 18:14:43 +00002175- Patch #1700288: added a type attribute cache that caches method
2176 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002177
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002178- Bug #1776: __import__() no longer accepts filenames on any platform.
2179 The first parameter to __import__() must be a valid module name.

2184 envvar and sys.dont_write_bytecode attribute. All these can be set
2185 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002186
Georg Brandl3ee81df2008-05-17 18:14:43 +00002187- Improve some exception messages when Windows fails to load an
2188 extension module. Now we get for example '%1 is not a valid Win32
2189 application' instead of 'error code 193'.

2246
Georg Brandl3ee81df2008-05-17 18:14:43 +00002247- The enumerate() builtin function is no longer bounded to sequences
2248 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2249 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002250
Georg Brandl3ee81df2008-05-17 18:14:43 +00002251- Issue #1686386: Tuple's tp_repr did not take into account the
2252 possibility of having a self-referential tuple, which is possible
2253 from C code. Nor did object's tp_str consider that a type's tp_str
2254 could do something that could lead to an inifinite recursion.
2255 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2256 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002257
Georg Brandl3ee81df2008-05-17 18:14:43 +00002258- Issue #1164: It was possible to trigger deadlock when using the
2259 'print' statement to write to a file since the GIL was not released
2260 as needed. Now PyObject_Print() does the right thing along with
2261 various tp_print implementations of the built-in types and those in
2262 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002263
Georg Brandl3ee81df2008-05-17 18:14:43 +00002264- Issue #1147: Exceptions were directly allowing string exceptions in

Georg Brandl3ee81df2008-05-17 18:14:43 +00002272 PyObject_Call() never calling back out to Python code to trigger
2273 recursion depth updates/checks. Required the creation of a static
2274 RuntimeError instance in case normalizing an exception put the
2275 recursion check value past its limit. Fixes crashers

2323
Guido van Rossum143b5642007-03-23 04:58:42 +00002324- Bug #1683368: The object.__init__() and object.__new__() methods are
2325 now stricter in rejecting excess arguments. The only time when
2326 either allows excess arguments is when it is not overridden and the
2327 other one is. For backwards compatibility, when both are
2328 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002329 warning later). Also, type.__init__() insists on the same signature
2330 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002332- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2333 object to complex using its __complex__() method before falling back
2334 to the __float__() method. Therefore, the functions in the cmath
2335 module now can operate on objects that define a __complex__()
2336 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00002354- Bug #1678647: write a newline after printing an exception in any
2355 case, even when converting the value to a string failed.
2356
Georg Brandl871f1bc2007-03-12 13:17:36 +00002357- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002358 its argument, if it exists. If not, it will work like before. This
2359 allows customizing the output of dir() in the presence of a
2360 __getattr__().

2370 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002371
Georg Brandlaa2321b2007-03-07 00:40:28 +00002372- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002373 makes the filenames the warning module prints much more sensible
2374 when a PYTHONSTARTUP file is used.

2388 sq_ass_slice instead of the sq_slice slot.
2389
Georg Brandl3ee81df2008-05-17 18:14:43 +00002390- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00002442- Bug #1545497: when given an explicit base, int() did ignore NULs
2443 embedded in the string to convert.
2444
Georg Brandl846f73a2006-10-08 07:11:54 +00002445- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00002493 generator expressions (x for x, in ... ) works again. Fixing this
2494 problem required changing the .pyc magic number. This means that
2495 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002925 AttributeError instead of an IOError when the server's response

3017 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00003298- The implementation of UnicodeError objects has been simplified
3299 (start and end attributes are now stored directly as Py_ssize_t
3300 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00003301
Georg Brandl3ee81df2008-05-17 18:14:43 +00003302- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3303 with RFC 3207 and forgets any knowledge obtained from the server not
3304 obtained from the TLS negotiation itself. Patch contributed by Bill
3305 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003306
Georg Brandl3ee81df2008-05-17 18:14:43 +00003307- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003308 that the SMTP.starttls() caller no longer needs to call ehlo()
3309 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003310 does not claim to support starttls. Adds the
3311 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3312 Fenner.

3392 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3393 silently miscode subclasses of those types. Now, it raises a
3394 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003395

Georg Brandl3ee81df2008-05-17 18:14:43 +00003410 time so that opening a database previously created with the DB_DUP
3411 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3412 opens. Specifically: dictionary assignment to a DB object will
3413 replace all values for a given key when the database allows
3414 duplicate values. DB users should use DB.put(k, v) when they want
3415 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003416

3422 characters with ASCII value less than 32. Also, it correctly quotes
3423 dots only if they occur on a single line, as opposed to the previous
3424 behavior of quoting dots if they are the second character of any
3425 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003426
