Vinay Sajip9c786582009-02-08 19:14:41 +0000312- Issue #5132: Fixed trouble building extensions under Solaris with
Tarek Ziadéf28849a2009-02-05 22:55:00 +0000313 --enabled-shared activated. Initial patch by Dave Peterson.
314
Guilherme Polob2dbd432009-02-02 21:15:41 +0000315- Issue #1581476: Always use the Tcl global namespace when calling into Tcl.
316
Antoine Pitrou4ad77e22009-01-29 20:30:51 +0000317- Issue #2047: shutil.move() could believe that its destination path was
318 inside its source path if it began with the same letters (e.g. "src" vs.
319 "src.new").
320
Raymond Hettingerc9794482009-01-28 23:14:58 +0000321- Issue 4920: Fixed .next() vs .__next__() issues in the ABCs for
322 Iterator and MutableSet.
323
Raymond Hettinger8c0cee82009-01-27 10:30:26 +0000324- Issue 5021: doctest.testfile() did not create __name__ and

331 allow adding directories to a zipfile.
332
Antoine Pitrou19fec8b2009-01-21 00:56:37 +0000333- Issue #5008: When a file is opened in append mode with the new IO library,
334 do an explicit seek to the end of file (so that e.g. tell() returns the
335 file size rather than 0). This is consistent with the behaviour of the
336 traditional 2.x file object.
337
Amaury Forgeot d'Arc0293c802009-01-17 16:46:35 +0000338- Issue #3997: zipfiles generated with more than 65536 files could not be

347
Raymond Hettingerd263bd82008-12-31 04:18:44 +0000348- Issue 4790: The nsmallest() and nlargest() functions in the heapq module
349 did unnecessary work in the common case where no key function was specified.
350

367 zipimport (or any other conformant PEP 302 loader). Original patch by
368 Alexander Belopolsky.
369
370- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
371 302 conformant loader) will now work correctly in most cases (they
372 are still subject to the constraints that exist for all code running
373 from inside a module loaded via a PEP 302 loader and attempting to
374 perform IO operations based on __file__). Original patch by
375 Alexander Belopolsky.

532What's New in Python 2.6.1
533==========================
534
535*Release date: 04-Dec-2008*
536
537Core and Builtins
538-----------------
539
540- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
541 interpreter to abort ("Fatal Python error: Could not reset the stack!")
542 instead of throwing a MemoryError.
543
544- Issue #4367: Python would segfault during compiling when the unicodedata
545 module couldn't be imported and \N escapes were present.
546
547- Issue #4348: Some bytearray methods returned that didn't cause any change to
548 the bytearray, returned the same bytearray instead of a copy.
549
550- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
551
552- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
553
554- Issue #4048: The parser module now correctly validates relative imports.
555
556- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
557 exec statement.
558
559- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
560 method does not return iterators for the 4th and 5th items.
561
562- Issue #4209: Enabling unicode_literals and the print_function in the same
563 __future__ import didn't work.
564
565- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
566 returned a path longer than MAX_PATH. (But It's doubtful this code path is
567 really executed because I cannot move to such directory on win2k)
568
569- Issue #4069: When set.remove(element) is used with a set element, the element
570 is temporarily replaced with an equivalent frozenset. But the eventual
571 KeyError would always report the empty frozenset([]) as the missing key. Now
572 it correctly refers to the initial element.
573
574- Fixed C99 style comments in several files. Python is now C89 compatible
575 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000722- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
723
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000724- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
725 PyString_FromFormat or PyErr_Format to display size_t values. The macro
726 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
727 ``printf`` function, whereas PyString_FromFormat has an independent
728 implementation and uses "%zd" on all platforms for size_t values.
729 This makes a difference on win64, where ``printf`` needs "%Id" to display
730 64bit values.
731
Benjamin Peterson97179b02008-09-09 20:55:01 +0000732- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
733 error.
734
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +0000735- Issue #3777: long() applied to a float object now always return a long
736 object; previously an int would be returned for small values. the __long__
737 method is allowed to return either an int or a long, but the behaviour of
738 float objects should not change to respect backward compatibility.
739
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000740- Issue #3751: str.rpartition would perform a left-partition when called with
741 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +0000746 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000747 was correctly parsed but parsing of subsequent arguments failed.
748
Vinay Sajip35e3b032008-09-01 14:33:59 +0000749- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000750 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
751 mechanism. In the process, fix a bug where isinstance() and issubclass(),
752 when given a tuple of classes as second argument, were looking up
753 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
754 type object.
755
Neal Norwitz18aa3882008-08-24 05:04:52 +0000756- Fix crashes on memory allocation failure found with failmalloc.

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

895Core and Builtins
896-----------------
897
Guido van Rossumf8402962008-08-20 15:01:50 +0000898- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
899 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
900 extensions do not automatically benefit from the class attribute
901 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
902 to their tp_flags field if they care. This is a backwards
903 compatibility feature; in 3.0, all types will use the cache by
904 default.
905
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000906- Keyword arguments can now follow starred arguments. (``f(a, *args,
907 keyword=23)`` is now valid syntax.)
908
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000909- ctypes function pointers that are COM methods have a boolean True
910 value again.
911
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000912- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
913 by denying s# to parse objects that have a releasebuffer procedure,
914 and introducing s*.
915
Georg Brandl1e13ea92008-08-11 09:07:59 +0000916- Issue #3537: Fix an assertion failure when an empty but presized dict
917 object was stored in the freelist.
918
Mark Dickinsonb6467572008-08-04 21:30:09 +0000919- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
920 ValueError consistently across platforms.
921
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000922- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
923 (64bit Unix, for example), unichr() would truncate its argument and return
924 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
925
Neal Norwitze7d8be82008-07-31 17:17:14 +0000926- Apply security patches from Apple.
927
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000928- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
929 PyErr_ExceptionMatches returns 0 when an exception occurs there.
930
Antoine Pitrou92f82162008-07-25 22:22:08 +0000931- Issue #1819: function calls with several named parameters are now on
932 average 35% faster (as measured by pybench).
933
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000934- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
935 the python debugger steps into a class statement: the free variables (local
936 variables defined in an outer scope) would be deleted from the outer scope.
937
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000938- Issue #2620: Overflow checking when allocating or reallocating memory
939 was not always being done properly in some python types and extension
940 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
941 all been updated to perform better checks and places in the code that
942 would previously leak memory on the error path when such an allocation
943 failed have been fixed.

951 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
952
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000953- Issue #2234: distutils failed for some versions of the cygwin compiler. The
954 version reported by these tools does not necessarily follow the python
955 version numbering scheme, so the module is less strict when parsing it.
956
Nick Coghlanf70385a2008-08-18 12:42:46 +0000957- Issue #2235: Added Py3k warnings for types which will become unhashable
958 under the stricter __hash__ inheritance rules in 3.0. Several types
959 which did not meet the rules for hash invariants and were already
960 unhashable in 3.0 have now been explicitly flagged as unhashable in
961 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
962 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
963
Brett Cannon88f801d2008-08-18 00:46:22 +0000964- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

972
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000973- Issue #3575: Incremental decoder's decode function now takes bytearray
974 by using 's*' instead of 't#'.
975
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000976- Issue #2222: Fixed reference leak when occured os.rename()
977 fails unicode conversion on 2nd parameter. (windows only)
978
Facundo Batista94f243a2008-08-17 03:38:39 +0000979- Issue 2464. urllib2 now supports a malformation in the URL received
980 in a redirect.

1011 to _sre.compile() will now be rejected. This should not affect anybody

Antoine Pitroude781a42008-08-09 12:43:23 +00001033 asking for a specific length. This problem only affected files opened

1077
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001078- Issue #643841: The language reference now provides more detailed

1090-----------------
1091
Georg Brandl3e483f62008-07-16 22:57:41 +00001092- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1093 its methods now allow for items objects that can be converted to
1094 an integer using operator.index().
1095
Mark Dickinson64b7e502008-07-16 09:40:03 +00001096- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1097 produced a ValueError instead of giving the correct float.
1098
Eric Smitha5fa5a22008-07-16 00:11:49 +00001099- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1100 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1101
Mark Dickinson7103aa42008-07-15 19:08:33 +00001102- Issue #3008: the float type has a new instance method 'float.hex'
1103 and a new class method 'float.fromhex' to convert floating-point
1104 numbers to and from hexadecimal strings, respectively.
1105
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001106- Issue #2235: __hash__ is once again inherited by default. To allow
1107 collections.Hashable to remain meaningful in the presence of the
1108 default hash implementation (object.__hash__), it is now possible
1109 to explicit block inheritance of hash by setting __hash__=None at
1110 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1111 level.
1112
Nick Coghlanb028f502008-07-13 14:52:36 +00001113- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1114 the parent module cannot be found while performing an absolute import.
1115 This means that an incorrectly defined __package__ attribute will
1116 now only prevent relative imports in that module rather than causing
1117 all imports from that module to fail.
1118
Nick Coghlan14ff9942008-07-08 14:21:42 +00001119- Issue #2517: Allow unicode messages in Exceptions again by correctly

1129 another thread's dictionary.
1130
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001131- Issue #3004: Minor change to slice.indices(): the start and stop
1132 arguments are now treated identically, making the behaviour easier
1133 to describe and understand. For example, slice(None, -10,
1134 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1135 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1136 10, -1).
1137
Georg Brandl278fc502008-07-19 12:46:12 +00001138- Issue #3219: Calling a function with repeated keyword arguments,
1139 f(a=2, a=23), would not cause a syntax error. This was a regression
1140 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00001142- Issue #2862: Make int and float freelist management consistent with
1143 other freelists. Changes their CompactFreeList apis into

1151 error when they failed.
1152
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001153- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001178- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1179 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001180 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001181 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001197- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1587
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001588- On MacOS X it is now possible to install the framework in 64-bit
1589 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001590 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001591
1592 This is controlled by the configure argument ``--with-universal-archs``:
1593
1594 - ``--with-universal-archs=all``: install 4-way universal
1595
1596 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1597
1598 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1599
1600 This option should be used in combination with ``--enable-universalsdk=``.
1601
1602 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 +00001652- Issue #1631171: Re-implement the 'warnings' module in C (the
1653 original Python code has been kept as backup). This will allow for
1654 using the 'warning's machinery in such places as the parser where
1655 use of pure Python code is not possible. Both the ``showarning()``
1656 and ``formatwarning()`` gain an optional 'line' argument which is
1657 not called by default for backwards-compatibility reasons. Setting
1658 ``warnings.showwarning()`` to an implementation that lacks support
1659 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001684- The getpass module has been improved on Unix. It now uses /dev/tty
1685 by default and uses stderr instead of stdout. A GetPassWarning is
1686 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001701- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001702 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00001722- Issue #2550: The approach used by client/server code for obtaining
1723 ports to listen on in network-oriented tests has been refined in an
1724 effort to facilitate running multiple instances of the entire
1725 regression test suite in parallel without issue.
1726 test_support.bind_port() has been fixed such that it will always
1727 return a unique port -- which wasn't always the case with the
1728 previous implementation, especially if socket options had been set
1729 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1730 new implementation of bind_port() will actually raise an exception
1731 if it is passed an AF_INET/SOCK_STREAM socket with either the
1732 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1733 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1734 the socket it's been passed. This currently only applies to
1735 Windows. This option prevents any other sockets from binding to the
1736 host/port we've bound to, thus removing the possibility of the
1737 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1738 when a second SOCK_STREAM socket binds and accepts to a host/port
1739 that's already been bound by another socket. The optional preferred
1740 port parameter to bind_port() has been removed. Under no
1741 circumstances should tests be hard coding ports!
1742
1743 test_support.find_unused_port() has also been introduced, which will
1744 pass a temporary socket object to bind_port() in order to obtain an
1745 unused port. The temporary socket object is then closed and
1746 deleted, and the port is returned. This method should only be used
1747 for obtaining an unused port in order to pass to an external program
1748 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1749 a parameter to a server-oriented class that doesn't give you direct
1750 access to the underlying socket used.
1751
1752 Finally, test_support.HOST has been introduced, which should be used
1753 for the host argument of any relevant socket calls (i.e. bind and
1754 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001755
1756 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001757 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001758 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1759 test_asynchat and test_socket_ssl.
1760
Georg Brandl3ee81df2008-05-17 18:14:43 +00001761 It is now possible for multiple instances of the regression test
1762 suite to run in parallel without issue.

2029-----------------
2030
Fred Drakea8ee94b2008-03-01 02:45:07 +00002031- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002032 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002037
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002038- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002039 issue 215555 for a discussion.
2040
Eric Smitha73fbe72008-02-23 03:09:44 +00002041- Added the future_builtins module, which contains hex() and oct().
2042 These are the PEP 3127 version of these functions, designed to be
2043 compatible with the hex() and oct() builtins from Python 3.0. They
2044 differ slightly in their output formats from the existing, unchanged
2045 Python 2.6 builtins. The expected usage of the future_builtins
2046 module is:
2047 from future_builtins import hex, oct
2048
Eric Smith7ef40bf2008-02-20 23:34:22 +00002049- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2050 exponents for exponents with absolute value < 100. Follows C99
2051 standard. This is a change on Windows, which would use 3 digits.
2052 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2053 so that any alterations it does to the resulting string will be
2054 available in stringlib/formatter.h (for float.__format__).
2055
Eric Smith5a3c1352008-02-19 13:21:56 +00002056- Implemented PEP 3101, Advanced String Formatting. This adds a new
2057 builtin format(); a format() method for str and unicode; a
2058 __format__() method to object, str, unicode, int, long, float, and
2059 datetime; the class string.Formatter; and the C API
2060 PyObject_Format().
2061
Georg Brandl3ee81df2008-05-17 18:14:43 +00002062- Fixed several potential crashes, all caused by specially crafted
2063 __del__ methods exploiting objects in temporarily inconsistent
2064 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002065
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002066- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002067 prevent a possible crash: an Abstract Base Class would try to access
2068 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002069
Georg Brandl3ee81df2008-05-17 18:14:43 +00002070- Fixed repr() and str() of complex numbers with infinity or nan as
2071 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002072
Georg Brandl3ee81df2008-05-17 18:14:43 +00002073- Clear all free lists during a gc.collect() of the highest generation
2074 in order to allow pymalloc to free more arenas. Python may give back
2075 memory to the OS earlier.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002077- Issue #2045: Fix an infinite recursion triggered when printing a
2078 subclass of collections.defaultdict, if its default_factory is set
2079 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002080
Christian Heimesf75dbef2008-02-08 00:11:31 +00002081- Fixed a minor memory leak in dictobject.c. The content of the free
2082 list was not freed on interpreter shutdown.
2083
Georg Brandl3ee81df2008-05-17 18:14:43 +00002084- Limit free list of method and builtin function objects to 256
2085 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002086
Georg Brandl3ee81df2008-05-17 18:14:43 +00002087- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2088 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002089 to compact the internal free lists of pre-allocted ints and floats.
2090
Georg Brandl3ee81df2008-05-17 18:14:43 +00002091- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2092 calls. Python expected the return type int but the fork familie
2093 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002094
Georg Brandl3ee81df2008-05-17 18:14:43 +00002095- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2096 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002097
Georg Brandl3ee81df2008-05-17 18:14:43 +00002098- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2099 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002100
Georg Brandl3ee81df2008-05-17 18:14:43 +00002101- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and

Georg Brandl3ee81df2008-05-17 18:14:43 +00002104- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2105 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002106
Georg Brandl3ee81df2008-05-17 18:14:43 +00002107- Patch #1473257: generator objects gain a gi_code attribute. This is
2108 the same object as the func_code attribute of the function that
2109 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002110
Georg Brandl3ee81df2008-05-17 18:14:43 +00002111- Issue #1920: "while 0" statements were completely removed by the
2112 compiler, even in the presence of an "else" clause, which is
2113 supposed to be run when the condition is false. Now the compiler
2114 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002115
Guido van Rossumeead05f2008-01-24 18:21:02 +00002116- A few crashers fixed: weakref_in_del.py (issue #1377858);
2117 loosing_dict_ref.py (issue #1303614, test67.py);
2118 borrowed_ref_[34].py (not in tracker).
2119
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002120- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002121 suppressed while an extension is loaded by calling SetErrorMode in
2122 dynload_win.c. The error is still reported properly.
2123
Georg Brandl3ee81df2008-05-17 18:14:43 +00002124- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002125 several extension methods and modules do not work without unicode
2126 support.
2127
Georg Brandl26543b12008-01-21 18:36:51 +00002128- Issue #1882: when compiling code from a string, encoding cookies in the
2129 second line of code were not always recognized correctly.
2130
Georg Brandl14404b62008-01-19 19:27:05 +00002131- Issue #1679: "0x" was taken as a valid integer literal.
2132
Georg Brandl6caad7d2008-01-26 14:19:22 +00002133- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002134 added.
2135
Christian Heimesc94e2b52008-01-14 04:13:37 +00002136- sys.float_info / PyFloat_GetInfo: The floating point information
2137 object was converted from a dict to a specialized structseq object.
2138
Georg Brandl3ee81df2008-05-17 18:14:43 +00002139- Patch #1816: Added sys.flags structseq. It exposes the status of
2140 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002141
Georg Brandl3ee81df2008-05-17 18:14:43 +00002142- Objects/structseq.c: Implemented new structseq representation. The
2143 patch makes structseqs (e.g. the return value of os.stat) more
2144 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002145
Georg Brandl3ee81df2008-05-17 18:14:43 +00002146- Patch #1700288: added a type attribute cache that caches method
2147 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002148
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002149- Bug #1776: __import__() no longer accepts filenames on any platform.
2150 The first parameter to __import__() must be a valid module name.

2153
Georg Brandl3ee81df2008-05-17 18:14:43 +00002154- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2155 envvar and sys.dont_write_bytecode attribute. All these can be set
2156 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002157
Georg Brandl3ee81df2008-05-17 18:14:43 +00002158- Improve some exception messages when Windows fails to load an
2159 extension module. Now we get for example '%1 is not a valid Win32
2160 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002161

Christian Heimes0a8143f2007-12-18 23:22:54 +00002167- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002168 and INF. float("nan"), float("inf") and float("-inf") now work on
2169 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002170
Georg Brandl3ee81df2008-05-17 18:14:43 +00002171- Compiler now generates simpler and faster code for dictionary
2172 literals. The oparg for BUILD_MAP now indicates an estimated
2173 dictionary size. There is a new opcode, STORE_MAP, for adding
2174 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002203- Patch #1739468: Directories and zipfiles containing a __main__.py
2204 file can now be directly executed by passing their name to the
2205 interpreter. The directory/zipfile is automatically inserted as the
2206 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002207
Georg Brandl3ee81df2008-05-17 18:14:43 +00002208- Issue #1265: Fix a problem with sys.settrace, if the tracing
2209 function uses a generator expression when at the same time the
2210 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002211
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002212- sets and frozensets now have an isdisjoint() method.
2213

2215
Neal Norwitz44f326e2007-10-05 05:29:17 +00002216- Fix warnings found by the new version of the Coverity checker.
2217
Georg Brandl3ee81df2008-05-17 18:14:43 +00002218- The enumerate() builtin function is no longer bounded to sequences
2219 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2220 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002221
Georg Brandl3ee81df2008-05-17 18:14:43 +00002222- Issue #1686386: Tuple's tp_repr did not take into account the
2223 possibility of having a self-referential tuple, which is possible
2224 from C code. Nor did object's tp_str consider that a type's tp_str
2225 could do something that could lead to an inifinite recursion.
2226 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2227 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002228
Georg Brandl3ee81df2008-05-17 18:14:43 +00002229- Issue #1164: It was possible to trigger deadlock when using the
2230 'print' statement to write to a file since the GIL was not released
2231 as needed. Now PyObject_Print() does the right thing along with
2232 various tp_print implementations of the built-in types and those in
2233 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002234
Georg Brandl3ee81df2008-05-17 18:14:43 +00002235- Issue #1147: Exceptions were directly allowing string exceptions in
2236 their throw() method even though string exceptions no longer
2237 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002238
Georg Brandl3ee81df2008-05-17 18:14:43 +00002239- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00002241
Brett Cannon1e534b52007-09-07 04:18:30 +00002242- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002243 PyObject_Call() never calling back out to Python code to trigger
2244 recursion depth updates/checks. Required the creation of a static
2245 RuntimeError instance in case normalizing an exception put the
2246 recursion check value past its limit. Fixes crashers
2247 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002248

Neal Norwitz0ac60192007-05-27 04:08:54 +00002262- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002263 __*__ attributes. (Some already existed, e.g., __doc__ and
2264 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002265
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002266- Add -3 option to the interpreter to warn about features that are
2267 deprecated and will be changed/removed in Python 3.0.
2268
Georg Brandl2134e752007-05-21 20:34:16 +00002269- Patch #1686487: you can now pass any mapping after '**' in function
2270 calls.
2271
Collin Winter62903052007-05-18 23:11:24 +00002272- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002273 "except E as target:". This is to provide forwards compatibility
2274 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00002276- Deprecate BaseException.message as per PEP 352.
2277
Georg Brandl3ee81df2008-05-17 18:14:43 +00002278- Issue #1303614: don't expose object's __dict__ when the dict is

2280
Vinay Sajip8549ce32007-05-06 17:53:37 +00002281- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002282 setting a plain string, ie don't expand to single letter identifiers.
2283
Raymond Hettinger13936692007-04-11 18:40:58 +00002284- Request #1191699: Slices can now be pickled.
2285
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002286- Request #1193128: str.translate() now allows a None argument for

2288 remaining characters.
2289
Georg Brandl5cb76c12007-03-21 09:00:39 +00002290- Patch #1682205: a TypeError while unpacking an iterable is no longer
2291 masked by a generic one with the message "unpack non-sequence".
2292
Neal Norwitzaa754b72007-03-21 06:39:48 +00002293- Remove unused file Python/fmod.c.
2294
Guido van Rossum143b5642007-03-23 04:58:42 +00002295- Bug #1683368: The object.__init__() and object.__new__() methods are
2296 now stricter in rejecting excess arguments. The only time when
2297 either allows excess arguments is when it is not overridden and the
2298 other one is. For backwards compatibility, when both are
2299 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002300 warning later). Also, type.__init__() insists on the same signature
2301 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002303- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2304 object to complex using its __complex__() method before falling back
2305 to the __float__() method. Therefore, the functions in the cmath
2306 module now can operate on objects that define a __complex__()
2307 method.

Georg Brandlaa2321b2007-03-07 00:40:28 +00002343- Patch #703779: unset __file__ in __main__ after running a file. This

2414 embedded in the string to convert.
2415
Georg Brandl846f73a2006-10-08 07:11:54 +00002416- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00002896 AttributeError instead of an IOError when the server's response

Georg Brandl92a6bae2007-03-13 17:43:32 +00002930- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002931 are set for invalid interpolation sequences that would lead to

2988 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00003381 time so that opening a database previously created with the DB_DUP
3382 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3383 opens. Specifically: dictionary assignment to a DB object will
3384 replace all values for a given key when the database allows
3385 duplicate values. DB users should use DB.put(k, v) when they want
3386 to store duplicates; not DB[k] = v.

3393 characters with ASCII value less than 32. Also, it correctly quotes
3394 dots only if they occur on a single line, as opposed to the previous
3395 behavior of quoting dots if they are the second character of any
3396 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003397
