105 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
106 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
107 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

140 processing: any non-float non-integer argument is now converted to
141 an integer (if possible) using its __int__ method. Previously, only

1746What's New in Python 2.6.1
1747==========================
1748
1749*Release date: 04-Dec-2008*
1750
1751Core and Builtins
1752-----------------
1753
1754- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1755 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1756 instead of throwing a MemoryError.
1757
1758- Issue #4367: Python would segfault during compiling when the unicodedata
1759 module couldn't be imported and \N escapes were present.
1760
1761- Issue #4348: Some bytearray methods returned that didn't cause any change to
1762 the bytearray, returned the same bytearray instead of a copy.
1763
1764- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1765
1766- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1767
1768- Issue #4048: The parser module now correctly validates relative imports.
1769
1770- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1771 exec statement.
1772
1773- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1774 method does not return iterators for the 4th and 5th items.
1775
1776- Issue #4209: Enabling unicode_literals and the print_function in the same
1777 __future__ import didn't work.
1778
1779- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1780 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1781 really executed because I cannot move to such directory on win2k)
1782
1783- Issue #4069: When set.remove(element) is used with a set element, the element
1784 is temporarily replaced with an equivalent frozenset. But the eventual
1785 KeyError would always report the empty frozenset([]) as the missing key. Now
1786 it correctly refers to the initial element.
1787
1788- Fixed C99 style comments in several files. Python is now C89 compatible
1789 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001936- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1937
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001938- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1939 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1940 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1941 ``printf`` function, whereas PyString_FromFormat has an independent
1942 implementation and uses "%zd" on all platforms for size_t values.
1943 This makes a difference on win64, where ``printf`` needs "%Id" to display
1944 64bit values.
1945
Benjamin Peterson97179b02008-09-09 20:55:01 +00001946- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1950 object; previously an int would be returned for small values. the __long__
1951 method is allowed to return either an int or a long, but the behaviour of
1952 float objects should not change to respect backward compatibility.
1953
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001954- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00001960 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001961 was correctly parsed but parsing of subsequent arguments failed.
1962
Vinay Sajip35e3b032008-09-01 14:33:59 +00001963- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001964 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1965 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1966 when given a tuple of classes as second argument, were looking up
1967 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1968 type object.
1969

Brett Cannon1eaf0742008-09-02 01:25:16 +00002039 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2040 for catch_warnings() also led to an improvement in the raising of a

2110-----------------
2111
Guido van Rossumf8402962008-08-20 15:01:50 +00002112- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2113 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2114 extensions do not automatically benefit from the class attribute
2115 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2116 to their tp_flags field if they care. This is a backwards
2117 compatibility feature; in 3.0, all types will use the cache by
2118 default.
2119
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002120- Keyword arguments can now follow starred arguments. (``f(a, *args,
2121 keyword=23)`` is now valid syntax.)
2122
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002123- ctypes function pointers that are COM methods have a boolean True
2124 value again.

Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002126- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2127 by denying s# to parse objects that have a releasebuffer procedure,
2128 and introducing s*.
2129
Georg Brandl1e13ea92008-08-11 09:07:59 +00002130- Issue #3537: Fix an assertion failure when an empty but presized dict
2131 object was stored in the freelist.
2132
Mark Dickinsonb6467572008-08-04 21:30:09 +00002133- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2134 ValueError consistently across platforms.
2135
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002136- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2137 (64bit Unix, for example), unichr() would truncate its argument and return
2138 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2139
Neal Norwitze7d8be82008-07-31 17:17:14 +00002140- Apply security patches from Apple.
2141
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002142- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2143 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2144
Antoine Pitrou92f82162008-07-25 22:22:08 +00002145- Issue #1819: function calls with several named parameters are now on
2146 average 35% faster (as measured by pybench).
2147
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002148- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2149 the python debugger steps into a class statement: the free variables (local
2150 variables defined in an outer scope) would be deleted from the outer scope.
2151
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002152- Issue #2620: Overflow checking when allocating or reallocating memory
2153 was not always being done properly in some python types and extension
2154 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2155 all been updated to perform better checks and places in the code that
2156 would previously leak memory on the error path when such an allocation
2157 failed have been fixed.

2165 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2166
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002167- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2168 version reported by these tools does not necessarily follow the python
2169 version numbering scheme, so the module is less strict when parsing it.
2170
Nick Coghlanf70385a2008-08-18 12:42:46 +00002171- Issue #2235: Added Py3k warnings for types which will become unhashable
2172 under the stricter __hash__ inheritance rules in 3.0. Several types
2173 which did not meet the rules for hash invariants and were already
2174 unhashable in 3.0 have now been explicitly flagged as unhashable in
2175 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2176 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2177
Brett Cannon88f801d2008-08-18 00:46:22 +00002178- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2179 imported into the module but exposed as part of the module's API.

Brett Cannonbf3157b2008-08-14 05:00:03 +00002209- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2210 since mimetools itself is deprecated. Because modules are cached, all
2211 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2212
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002213- Issue #3134: shutil referenced undefined WindowsError symbol.

2222 a MemoryError rather than silently stop the iteration.
2223
Guido van Rossum59ce9012008-08-09 14:55:34 +00002224- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2225 to _sre.compile() will now be rejected. This should not affect anybody
2226 since the re.compile() function never generates invalid re-bytecode.
2227
Skip Montanaroa032bf42008-08-08 22:52:51 +00002228- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2229 upon first access it can be automatically initialized from the csv file if
2230 it wasn't initialized during instantiation.
2231
Brett Cannon3aa2a492008-08-06 22:28:09 +00002232- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2233 the reload() built-in has been removed.
2234
Brett Cannon7e30b672008-08-04 21:52:25 +00002235- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002236 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002247 asking for a specific length. This problem only affected files opened
2248 using the new "io" module, not the built-in open() function.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002273- Issue #3394: zipfile.writestr sets external attributes when passed a
2274 file name rather than a ZipInfo instance, so files are extracted with
2275 mode 0600 rather than 000 under Unix.
2276
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002277- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2278 argument in python 2.5, this broke code that subclassed Popen to include its

2290 interaction with the tp_hash slot (added in 2.6b2) are now documented
2291
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002292- Issue #643841: The language reference now provides more detailed
2293 coverage of the lookup process for special methods. The disclaimers
2294 regarding lack of coverage of new-style classes have also been
2295 removed, since the coverage is now fairly reasonable.

2299================================
2300
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002301*Release date: 17-Jul-2008*
2302
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002303Core and Builtins
2304-----------------
2305
Georg Brandl3e483f62008-07-16 22:57:41 +00002306- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2307 its methods now allow for items objects that can be converted to
2308 an integer using operator.index().
2309
Mark Dickinson64b7e502008-07-16 09:40:03 +00002310- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2311 produced a ValueError instead of giving the correct float.
2312
Eric Smitha5fa5a22008-07-16 00:11:49 +00002313- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2314 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2315
Mark Dickinson7103aa42008-07-15 19:08:33 +00002316- Issue #3008: the float type has a new instance method 'float.hex'
2317 and a new class method 'float.fromhex' to convert floating-point
2318 numbers to and from hexadecimal strings, respectively.
2319
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002320- Issue #2235: __hash__ is once again inherited by default. To allow
2321 collections.Hashable to remain meaningful in the presence of the
2322 default hash implementation (object.__hash__), it is now possible
2323 to explicit block inheritance of hash by setting __hash__=None at
2324 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2325 level.
2326
Nick Coghlanb028f502008-07-13 14:52:36 +00002327- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2328 the parent module cannot be found while performing an absolute import.
2329 This means that an incorrectly defined __package__ attribute will
2330 now only prevent relative imports in that module rather than causing
2331 all imports from that module to fail.
2332
Nick Coghlan14ff9942008-07-08 14:21:42 +00002333- Issue #2517: Allow unicode messages in Exceptions again by correctly
2334 bypassing the instance dictionary when looking up __unicode__ on
2335 new-style classes.
2336
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002337- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2338 set to a custom object whose write() method happens to install
2339 another file in sys.stdout.
2340
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002341- Issue #3088: Corrected a race condition in classes derived from
2342 threading.local: the first member set by a thread could be saved in
2343 another thread's dictionary.
2344
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002345- Issue #3004: Minor change to slice.indices(): the start and stop
2346 arguments are now treated identically, making the behaviour easier
2347 to describe and understand. For example, slice(None, -10,
2348 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2349 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2350 10, -1).
2351
Georg Brandl278fc502008-07-19 12:46:12 +00002352- Issue #3219: Calling a function with repeated keyword arguments,
2353 f(a=2, a=23), would not cause a syntax error. This was a regression
2354 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002355
Georg Brandl278fc502008-07-19 12:46:12 +00002356- Issue #2862: Make int and float freelist management consistent with
2357 other freelists. Changes their CompactFreeList apis into
2358 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00002363- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2364 api functions without holding the GIL, which could lead to a fatal
2365 error when they failed.
2366
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002367- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002375- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2376 ForkingPickler.register() to resolve conflict with ctypes.
2377
Vinay Sajip51e65192008-07-18 09:01:10 +00002378- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00002380- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2381 a valid dlerror() message.
2382
Thomas Heller2bad6572008-07-15 17:19:50 +00002383- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2384 incomplete structure was created.
2385

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002390- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002391
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002392- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2393 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002394 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002395 content-length. The problem had been corrected in the 2.4 branch, but never
2396 merged into trunk.
2397
Georg Brandle78fbcc2008-07-05 10:13:36 +00002398- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002411- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2412 handling is now the same as that of other special attributes like __name__).
2413
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002414- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2415 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00002804 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002805
2806 This is controlled by the configure argument ``--with-universal-archs``:
2807
2808 - ``--with-universal-archs=all``: install 4-way universal
2809
2810 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2811
2812 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2813
2814 This option should be used in combination with ``--enable-universalsdk=``.
2815
2816 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 +00002866- Issue #1631171: Re-implement the 'warnings' module in C (the
2867 original Python code has been kept as backup). This will allow for
2868 using the 'warning's machinery in such places as the parser where
2869 use of pure Python code is not possible. Both the ``showarning()``
2870 and ``formatwarning()`` gain an optional 'line' argument which is
2871 not called by default for backwards-compatibility reasons. Setting
2872 ``warnings.showwarning()`` to an implementation that lacks support
2873 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002936- Issue #2550: The approach used by client/server code for obtaining
2937 ports to listen on in network-oriented tests has been refined in an
2938 effort to facilitate running multiple instances of the entire
2939 regression test suite in parallel without issue.
2940 test_support.bind_port() has been fixed such that it will always
2941 return a unique port -- which wasn't always the case with the
2942 previous implementation, especially if socket options had been set
2943 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2944 new implementation of bind_port() will actually raise an exception
2945 if it is passed an AF_INET/SOCK_STREAM socket with either the
2946 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2947 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2948 the socket it's been passed. This currently only applies to
2949 Windows. This option prevents any other sockets from binding to the
2950 host/port we've bound to, thus removing the possibility of the
2951 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2952 when a second SOCK_STREAM socket binds and accepts to a host/port
2953 that's already been bound by another socket. The optional preferred
2954 port parameter to bind_port() has been removed. Under no
2955 circumstances should tests be hard coding ports!
2956
2957 test_support.find_unused_port() has also been introduced, which will
2958 pass a temporary socket object to bind_port() in order to obtain an
2959 unused port. The temporary socket object is then closed and
2960 deleted, and the port is returned. This method should only be used
2961 for obtaining an unused port in order to pass to an external program
2962 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2963 a parameter to a server-oriented class that doesn't give you direct
2964 access to the underlying socket used.
2965
2966 Finally, test_support.HOST has been introduced, which should be used
2967 for the host argument of any relevant socket calls (i.e. bind and
2968 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002969
2970 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002971 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002972 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2973 test_asynchat and test_socket_ssl.
2974
Georg Brandl3ee81df2008-05-17 18:14:43 +00002975 It is now possible for multiple instances of the regression test

Fred Drakea8ee94b2008-03-01 02:45:07 +00003245- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003246 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003247
Georg Brandlad61bc82008-02-23 15:11:18 +00003248- Issue #2067: file.__exit__() now calls subclasses' close() method.
3249
3250- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003251
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003252- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl21896072010-08-01 22:31:28 +00003253 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00003254
Eric Smitha73fbe72008-02-23 03:09:44 +00003255- Added the future_builtins module, which contains hex() and oct().
3256 These are the PEP 3127 version of these functions, designed to be
3257 compatible with the hex() and oct() builtins from Python 3.0. They
3258 differ slightly in their output formats from the existing, unchanged
3259 Python 2.6 builtins. The expected usage of the future_builtins
3260 module is:
3261 from future_builtins import hex, oct
3262
Eric Smith7ef40bf2008-02-20 23:34:22 +00003263- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3264 exponents for exponents with absolute value < 100. Follows C99
3265 standard. This is a change on Windows, which would use 3 digits.
3266 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3267 so that any alterations it does to the resulting string will be
3268 available in stringlib/formatter.h (for float.__format__).
3269
Eric Smith5a3c1352008-02-19 13:21:56 +00003270- Implemented PEP 3101, Advanced String Formatting. This adds a new
3271 builtin format(); a format() method for str and unicode; a
3272 __format__() method to object, str, unicode, int, long, float, and
3273 datetime; the class string.Formatter; and the C API
3274 PyObject_Format().
3275
Georg Brandl3ee81df2008-05-17 18:14:43 +00003276- Fixed several potential crashes, all caused by specially crafted
3277 __del__ methods exploiting objects in temporarily inconsistent
3278 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003279
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003280- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003281 prevent a possible crash: an Abstract Base Class would try to access
3282 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003283
Georg Brandl3ee81df2008-05-17 18:14:43 +00003284- Fixed repr() and str() of complex numbers with infinity or nan as
3285 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003286
Georg Brandl3ee81df2008-05-17 18:14:43 +00003287- Clear all free lists during a gc.collect() of the highest generation
3288 in order to allow pymalloc to free more arenas. Python may give back
3289 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003290
Georg Brandl3ee81df2008-05-17 18:14:43 +00003291- Issue #2045: Fix an infinite recursion triggered when printing a
3292 subclass of collections.defaultdict, if its default_factory is set
3293 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003294
Christian Heimesf75dbef2008-02-08 00:11:31 +00003295- Fixed a minor memory leak in dictobject.c. The content of the free
3296 list was not freed on interpreter shutdown.
3297
Georg Brandl5a7eca12010-03-21 19:29:04 +00003298- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003299 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003300
Georg Brandl3ee81df2008-05-17 18:14:43 +00003301- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3302 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003303 to compact the internal free lists of pre-allocted ints and floats.
3304
Georg Brandl3ee81df2008-05-17 18:14:43 +00003305- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3306 calls. Python expected the return type int but the fork familie
3307 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003308
Georg Brandl3ee81df2008-05-17 18:14:43 +00003309- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3310 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003311
Georg Brandl3ee81df2008-05-17 18:14:43 +00003312- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3313 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003314
Georg Brandl3ee81df2008-05-17 18:14:43 +00003315- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3316 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003317
Georg Brandl3ee81df2008-05-17 18:14:43 +00003318- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3319 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003320
Georg Brandl3ee81df2008-05-17 18:14:43 +00003321- Patch #1473257: generator objects gain a gi_code attribute. This is
3322 the same object as the func_code attribute of the function that
3323 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003324
Georg Brandl3ee81df2008-05-17 18:14:43 +00003325- Issue #1920: "while 0" statements were completely removed by the
3326 compiler, even in the presence of an "else" clause, which is
3327 supposed to be run when the condition is false. Now the compiler
3328 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003329
Guido van Rossumeead05f2008-01-24 18:21:02 +00003330- A few crashers fixed: weakref_in_del.py (issue #1377858);
3331 loosing_dict_ref.py (issue #1303614, test67.py);
3332 borrowed_ref_[34].py (not in tracker).
3333
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003334- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003335 suppressed while an extension is loaded by calling SetErrorMode in
3336 dynload_win.c. The error is still reported properly.
3337
Georg Brandl3ee81df2008-05-17 18:14:43 +00003338- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003339 several extension methods and modules do not work without unicode
3340 support.
3341
Georg Brandl26543b12008-01-21 18:36:51 +00003342- Issue #1882: when compiling code from a string, encoding cookies in the
3343 second line of code were not always recognized correctly.
3344
Georg Brandl14404b62008-01-19 19:27:05 +00003345- Issue #1679: "0x" was taken as a valid integer literal.
3346
Georg Brandl6caad7d2008-01-26 14:19:22 +00003347- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003348 added.
3349
Christian Heimesc94e2b52008-01-14 04:13:37 +00003350- sys.float_info / PyFloat_GetInfo: The floating point information
3351 object was converted from a dict to a specialized structseq object.
3352
Georg Brandl3ee81df2008-05-17 18:14:43 +00003353- Patch #1816: Added sys.flags structseq. It exposes the status of
3354 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003355
Georg Brandl3ee81df2008-05-17 18:14:43 +00003356- Objects/structseq.c: Implemented new structseq representation. The
3357 patch makes structseqs (e.g. the return value of os.stat) more
3358 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003359
Georg Brandl3ee81df2008-05-17 18:14:43 +00003360- Patch #1700288: added a type attribute cache that caches method
3361 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003362
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003363- Bug #1776: __import__() no longer accepts filenames on any platform.
3364 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003365

3367
Georg Brandl3ee81df2008-05-17 18:14:43 +00003368- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3369 envvar and sys.dont_write_bytecode attribute. All these can be set
3370 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003371
Georg Brandl3ee81df2008-05-17 18:14:43 +00003372- Improve some exception messages when Windows fails to load an
3373 extension module. Now we get for example '%1 is not a valid Win32
3374 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003375
Georg Brandl3ee81df2008-05-17 18:14:43 +00003376- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003378- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3379 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003380
Christian Heimes0a8143f2007-12-18 23:22:54 +00003381- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003382 and INF. float("nan"), float("inf") and float("-inf") now work on
3383 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003384
Georg Brandl3ee81df2008-05-17 18:14:43 +00003385- Compiler now generates simpler and faster code for dictionary
3386 literals. The oparg for BUILD_MAP now indicates an estimated
3387 dictionary size. There is a new opcode, STORE_MAP, for adding
3388 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003389
Georg Brandl3ee81df2008-05-17 18:14:43 +00003390- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003395- Issue #1538: Avoid copying string in split/rsplit if the split char
3396 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003397
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003398- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003399 SystemError.
3400
Nick Coghlanef01d822007-12-03 12:55:17 +00003401- PEP 366: Allow explicit relative imports when executing modules

3418 file can now be directly executed by passing their name to the
3419 interpreter. The directory/zipfile is automatically inserted as the
3420 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003421
Georg Brandl3ee81df2008-05-17 18:14:43 +00003422- Issue #1265: Fix a problem with sys.settrace, if the tracing
3423 function uses a generator expression when at the same time the
3424 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003425
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003426- sets and frozensets now have an isdisjoint() method.
3427
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003428- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00003430- Fix warnings found by the new version of the Coverity checker.
3431
Georg Brandl5a7eca12010-03-21 19:29:04 +00003432- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003433 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3434 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003435
Georg Brandl3ee81df2008-05-17 18:14:43 +00003436- Issue #1686386: Tuple's tp_repr did not take into account the
3437 possibility of having a self-referential tuple, which is possible
3438 from C code. Nor did object's tp_str consider that a type's tp_str
3439 could do something that could lead to an inifinite recursion.
3440 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3441 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003442
Georg Brandl3ee81df2008-05-17 18:14:43 +00003443- Issue #1164: It was possible to trigger deadlock when using the
3444 'print' statement to write to a file since the GIL was not released
3445 as needed. Now PyObject_Print() does the right thing along with
3446 various tp_print implementations of the built-in types and those in
3447 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003448
Georg Brandl3ee81df2008-05-17 18:14:43 +00003449- Issue #1147: Exceptions were directly allowing string exceptions in
3450 their throw() method even though string exceptions no longer
3451 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003452

Brett Cannon1e534b52007-09-07 04:18:30 +00003456- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003457 PyObject_Call() never calling back out to Python code to trigger
3458 recursion depth updates/checks. Required the creation of a static
3459 RuntimeError instance in case normalizing an exception put the
3460 recursion check value past its limit. Fixes crashers
3461 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003462
Georg Brandl3ee81df2008-05-17 18:14:43 +00003463- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003476- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003477 __*__ attributes. (Some already existed, e.g., __doc__ and
3478 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003479
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003480- Add -3 option to the interpreter to warn about features that are
3481 deprecated and will be changed/removed in Python 3.0.
3482
Georg Brandl2134e752007-05-21 20:34:16 +00003483- Patch #1686487: you can now pass any mapping after '**' in function
3484 calls.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003487 "except E as target:". This is to provide forwards compatibility
3488 with Python 3.0.

Guido van Rossum143b5642007-03-23 04:58:42 +00003509- Bug #1683368: The object.__init__() and object.__new__() methods are
3510 now stricter in rejecting excess arguments. The only time when
3511 either allows excess arguments is when it is not overridden and the
3512 other one is. For backwards compatibility, when both are
3513 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003514 warning later). Also, type.__init__() insists on the same signature
3515 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003517- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3518 object to complex using its __complex__() method before falling back
3519 to the __float__() method. Therefore, the functions in the cmath
3520 module now can operate on objects that define a __complex__()
3521 method.

3541
Georg Brandl871f1bc2007-03-12 13:17:36 +00003542- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003543 its argument, if it exists. If not, it will work like before. This
3544 allows customizing the output of dir() in the presence of a

3555 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00003557- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003558 makes the filenames the warning module prints much more sensible
3559 when a PYTHONSTARTUP file is used.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004487- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4488 with RFC 3207 and forgets any knowledge obtained from the server not
4489 obtained from the TLS negotiation itself. Patch contributed by Bill
4490 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004491
Georg Brandl3ee81df2008-05-17 18:14:43 +00004492- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004493 that the SMTP.starttls() caller no longer needs to call ehlo()
4494 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004495 does not claim to support starttls. Adds the
4496 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4577 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4578 silently miscode subclasses of those types. Now, it raises a
4579 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004580

Georg Brandl3ee81df2008-05-17 18:14:43 +00004595 time so that opening a database previously created with the DB_DUP
4596 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4597 opens. Specifically: dictionary assignment to a DB object will
4598 replace all values for a given key when the database allows
4599 duplicate values. DB users should use DB.put(k, v) when they want
4600 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004601

4607 characters with ASCII value less than 32. Also, it correctly quotes
4608 dots only if they occur on a single line, as opposed to the previous
4609 behavior of quoting dots if they are the second character of any
4610 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004611

Georg Brandl3ee81df2008-05-17 18:14:43 +00004955- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4956 of w# format code incorrectly truncated the length to an int, even
4957 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4958 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004960- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4961 Py_TYPE and Py_REFCNT.

4978- Fix some leftovers from the conversion from int to Py_ssize_t
4979 (relevant to strings and sequences of more than 2**31 items).
4980
4981- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4982 outside of pystate.c and should not be necessary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004988- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4989 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004990
Georg Brandl3ee81df2008-05-17 18:14:43 +00004991- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004998- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4999 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5000 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5001 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005016- Removed the macfs module. It had been deprecated since Python 2.5.
5017 This lead to the deprecation of macostools.touched() as it relied
5018 solely on macfs and was a no-op under OS X.
