1784What's New in Python 2.6.1
1785==========================
1786
1787*Release date: 04-Dec-2008*
1788
1789Core and Builtins
1790-----------------
1791
1792- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1793 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1794 instead of throwing a MemoryError.
1795
1796- Issue #4367: Python would segfault during compiling when the unicodedata
1797 module couldn't be imported and \N escapes were present.
1798
1799- Issue #4348: Some bytearray methods returned that didn't cause any change to
1800 the bytearray, returned the same bytearray instead of a copy.
1801
1802- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1803
1804- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1805
1806- Issue #4048: The parser module now correctly validates relative imports.
1807
1808- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1809 exec statement.
1810
1811- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1812 method does not return iterators for the 4th and 5th items.
1813
1814- Issue #4209: Enabling unicode_literals and the print_function in the same
1815 __future__ import didn't work.
1816
1817- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1818 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1819 really executed because I cannot move to such directory on win2k)
1820
1821- Issue #4069: When set.remove(element) is used with a set element, the element
1822 is temporarily replaced with an equivalent frozenset. But the eventual
1823 KeyError would always report the empty frozenset([]) as the missing key. Now
1824 it correctly refers to the initial element.
1825
1826- Fixed C99 style comments in several files. Python is now C89 compatible
1827 again.

1975
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001976- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1977 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1978 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1979 ``printf`` function, whereas PyString_FromFormat has an independent
1980 implementation and uses "%zd" on all platforms for size_t values.
1981 This makes a difference on win64, where ``printf`` needs "%Id" to display
1982 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001999 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002001- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002002 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2003 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2004 when given a tuple of classes as second argument, were looking up
2005 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2006 type object.

2148-----------------
2149
Guido van Rossumf8402962008-08-20 15:01:50 +00002150- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2151 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2152 extensions do not automatically benefit from the class attribute
2153 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2154 to their tp_flags field if they care. This is a backwards
2155 compatibility feature; in 3.0, all types will use the cache by
2156 default.
2157
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002158- Keyword arguments can now follow starred arguments. (``f(a, *args,

Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002164- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2165 by denying s# to parse objects that have a releasebuffer procedure,
2166 and introducing s*.
2167
Georg Brandl1e13ea92008-08-11 09:07:59 +00002168- Issue #3537: Fix an assertion failure when an empty but presized dict
2169 object was stored in the freelist.
2170
Mark Dickinsonb6467572008-08-04 21:30:09 +00002171- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2172 ValueError consistently across platforms.
2173
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002174- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2175 (64bit Unix, for example), unichr() would truncate its argument and return
2176 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2177
Neal Norwitze7d8be82008-07-31 17:17:14 +00002178- Apply security patches from Apple.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002180- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2181 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2182
Antoine Pitrou92f82162008-07-25 22:22:08 +00002183- Issue #1819: function calls with several named parameters are now on
2184 average 35% faster (as measured by pybench).
2185
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002186- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2187 the python debugger steps into a class statement: the free variables (local
2188 variables defined in an outer scope) would be deleted from the outer scope.
2189
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002190- Issue #2620: Overflow checking when allocating or reallocating memory
2191 was not always being done properly in some python types and extension
2192 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2193 all been updated to perform better checks and places in the code that
2194 would previously leak memory on the error path when such an allocation
2195 failed have been fixed.

2201
Benjamin Petersone977ad42008-08-20 01:42:01 +00002202- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2203 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2204
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002205- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2206 version reported by these tools does not necessarily follow the python
2207 version numbering scheme, so the module is less strict when parsing it.
2208
Nick Coghlanf70385a2008-08-18 12:42:46 +00002209- Issue #2235: Added Py3k warnings for types which will become unhashable
2210 under the stricter __hash__ inheritance rules in 3.0. Several types
2211 which did not meet the rules for hash invariants and were already
2212 unhashable in 3.0 have now been explicitly flagged as unhashable in
2213 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2214 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2215
Brett Cannon88f801d2008-08-18 00:46:22 +00002216- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2239
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002240- Issue #2676: in the email package, content-type parsing was hanging on
2241 pathological input because of quadratic or exponential behaviour of a
2242 regular expression.

Brett Cannonbf3157b2008-08-14 05:00:03 +00002247- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2248 since mimetools itself is deprecated. Because modules are cached, all
2249 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2250
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002251- Issue #3134: shutil referenced undefined WindowsError symbol.

2260 a MemoryError rather than silently stop the iteration.
2261
Guido van Rossum59ce9012008-08-09 14:55:34 +00002262- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2263 to _sre.compile() will now be rejected. This should not affect anybody
2264 since the re.compile() function never generates invalid re-bytecode.
2265
Skip Montanaroa032bf42008-08-08 22:52:51 +00002266- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2267 upon first access it can be automatically initialized from the csv file if
2268 it wasn't initialized during instantiation.
2269
Brett Cannon3aa2a492008-08-06 22:28:09 +00002270- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2271 the reload() built-in has been removed.
2272
Brett Cannon7e30b672008-08-04 21:52:25 +00002273- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002274 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002285 asking for a specific length. This problem only affected files opened
2286 using the new "io" module, not the built-in open() function.

2312 file name rather than a ZipInfo instance, so files are extracted with
2313 mode 0600 rather than 000 under Unix.
2314
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002315- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2316 argument in python 2.5, this broke code that subclassed Popen to include its
2317 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002327- Issue #2235: the C API function PyObject_HashNotImplemented and its
2328 interaction with the tp_hash slot (added in 2.6b2) are now documented
2329
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002330- Issue #643841: The language reference now provides more detailed
2331 coverage of the lookup process for special methods. The disclaimers
2332 regarding lack of coverage of new-style classes have also been
2333 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002341Core and Builtins
2342-----------------
2343
Georg Brandl3e483f62008-07-16 22:57:41 +00002344- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2345 its methods now allow for items objects that can be converted to
2346 an integer using operator.index().
2347
Mark Dickinson64b7e502008-07-16 09:40:03 +00002348- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2349 produced a ValueError instead of giving the correct float.
2350
Eric Smitha5fa5a22008-07-16 00:11:49 +00002351- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2352 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2353
Mark Dickinson7103aa42008-07-15 19:08:33 +00002354- Issue #3008: the float type has a new instance method 'float.hex'
2355 and a new class method 'float.fromhex' to convert floating-point
2356 numbers to and from hexadecimal strings, respectively.
2357
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002358- Issue #2235: __hash__ is once again inherited by default. To allow
2359 collections.Hashable to remain meaningful in the presence of the
2360 default hash implementation (object.__hash__), it is now possible
2361 to explicit block inheritance of hash by setting __hash__=None at
2362 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2363 level.
2364
Nick Coghlanb028f502008-07-13 14:52:36 +00002365- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2366 the parent module cannot be found while performing an absolute import.
2367 This means that an incorrectly defined __package__ attribute will
2368 now only prevent relative imports in that module rather than causing
2369 all imports from that module to fail.
2370
Nick Coghlan14ff9942008-07-08 14:21:42 +00002371- Issue #2517: Allow unicode messages in Exceptions again by correctly
2372 bypassing the instance dictionary when looking up __unicode__ on
2373 new-style classes.
2374
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002375- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2376 set to a custom object whose write() method happens to install
2377 another file in sys.stdout.
2378
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002379- Issue #3088: Corrected a race condition in classes derived from
2380 threading.local: the first member set by a thread could be saved in
2381 another thread's dictionary.
2382
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002383- Issue #3004: Minor change to slice.indices(): the start and stop
2384 arguments are now treated identically, making the behaviour easier
2385 to describe and understand. For example, slice(None, -10,
2386 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2387 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2388 10, -1).
2389
Georg Brandl278fc502008-07-19 12:46:12 +00002390- Issue #3219: Calling a function with repeated keyword arguments,
2391 f(a=2, a=23), would not cause a syntax error. This was a regression
2392 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002393
Georg Brandl278fc502008-07-19 12:46:12 +00002394- Issue #2862: Make int and float freelist management consistent with
2395 other freelists. Changes their CompactFreeList apis into
2396 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00002401- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2402 api functions without holding the GIL, which could lead to a fatal
2403 error when they failed.
2404
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002405- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2419 a valid dlerror() message.
2420
Thomas Heller2bad6572008-07-15 17:19:50 +00002421- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2422 incomplete structure was created.
2423

2427
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002428- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002429
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002430- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2431 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002432 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002433 content-length. The problem had been corrected in the 2.4 branch, but never
2434 merged into trunk.
2435
Georg Brandle78fbcc2008-07-05 10:13:36 +00002436- Issue #2663: add filtering capability to shutil.copytree().

2841 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002842 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002843
2844 This is controlled by the configure argument ``--with-universal-archs``:
2845
2846 - ``--with-universal-archs=all``: install 4-way universal
2847
2848 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2849
2850 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2851
2852 This option should be used in combination with ``--enable-universalsdk=``.
2853
2854 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 +00002904- Issue #1631171: Re-implement the 'warnings' module in C (the
2905 original Python code has been kept as backup). This will allow for
2906 using the 'warning's machinery in such places as the parser where
2907 use of pure Python code is not possible. Both the ``showarning()``
2908 and ``formatwarning()`` gain an optional 'line' argument which is
2909 not called by default for backwards-compatibility reasons. Setting
2910 ``warnings.showwarning()`` to an implementation that lacks support
2911 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002936- The getpass module has been improved on Unix. It now uses /dev/tty
2937 by default and uses stderr instead of stdout. A GetPassWarning is
2938 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002974- Issue #2550: The approach used by client/server code for obtaining
2975 ports to listen on in network-oriented tests has been refined in an
2976 effort to facilitate running multiple instances of the entire
2977 regression test suite in parallel without issue.
2978 test_support.bind_port() has been fixed such that it will always
2979 return a unique port -- which wasn't always the case with the
2980 previous implementation, especially if socket options had been set
2981 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2982 new implementation of bind_port() will actually raise an exception
2983 if it is passed an AF_INET/SOCK_STREAM socket with either the
2984 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2985 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2986 the socket it's been passed. This currently only applies to
2987 Windows. This option prevents any other sockets from binding to the
2988 host/port we've bound to, thus removing the possibility of the
2989 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2990 when a second SOCK_STREAM socket binds and accepts to a host/port
2991 that's already been bound by another socket. The optional preferred
2992 port parameter to bind_port() has been removed. Under no
2993 circumstances should tests be hard coding ports!
2994
2995 test_support.find_unused_port() has also been introduced, which will
2996 pass a temporary socket object to bind_port() in order to obtain an
2997 unused port. The temporary socket object is then closed and
2998 deleted, and the port is returned. This method should only be used
2999 for obtaining an unused port in order to pass to an external program
3000 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3001 a parameter to a server-oriented class that doesn't give you direct
3002 access to the underlying socket used.
3003
3004 Finally, test_support.HOST has been introduced, which should be used
3005 for the host argument of any relevant socket calls (i.e. bind and
3006 connect).

3282
Fred Drakea8ee94b2008-03-01 02:45:07 +00003283- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003284 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003285
Georg Brandlad61bc82008-02-23 15:11:18 +00003286- Issue #2067: file.__exit__() now calls subclasses' close() method.
3287
3288- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003289
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003290- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl21896072010-08-01 22:31:28 +00003291 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00003292
Eric Smitha73fbe72008-02-23 03:09:44 +00003293- Added the future_builtins module, which contains hex() and oct().
3294 These are the PEP 3127 version of these functions, designed to be
3295 compatible with the hex() and oct() builtins from Python 3.0. They
3296 differ slightly in their output formats from the existing, unchanged
3297 Python 2.6 builtins. The expected usage of the future_builtins
3298 module is:
3299 from future_builtins import hex, oct
3300
Eric Smith7ef40bf2008-02-20 23:34:22 +00003301- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3302 exponents for exponents with absolute value < 100. Follows C99
3303 standard. This is a change on Windows, which would use 3 digits.
3304 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3305 so that any alterations it does to the resulting string will be
3306 available in stringlib/formatter.h (for float.__format__).
3307
Eric Smith5a3c1352008-02-19 13:21:56 +00003308- Implemented PEP 3101, Advanced String Formatting. This adds a new
3309 builtin format(); a format() method for str and unicode; a
3310 __format__() method to object, str, unicode, int, long, float, and
3311 datetime; the class string.Formatter; and the C API
3312 PyObject_Format().
3313
Georg Brandl3ee81df2008-05-17 18:14:43 +00003314- Fixed several potential crashes, all caused by specially crafted
3315 __del__ methods exploiting objects in temporarily inconsistent
3316 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003317
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003318- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003319 prevent a possible crash: an Abstract Base Class would try to access
3320 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003321
Georg Brandl3ee81df2008-05-17 18:14:43 +00003322- Fixed repr() and str() of complex numbers with infinity or nan as
3323 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003324
Georg Brandl3ee81df2008-05-17 18:14:43 +00003325- Clear all free lists during a gc.collect() of the highest generation
3326 in order to allow pymalloc to free more arenas. Python may give back
3327 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003328
Georg Brandl3ee81df2008-05-17 18:14:43 +00003329- Issue #2045: Fix an infinite recursion triggered when printing a
3330 subclass of collections.defaultdict, if its default_factory is set
3331 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003332
Christian Heimesf75dbef2008-02-08 00:11:31 +00003333- Fixed a minor memory leak in dictobject.c. The content of the free
3334 list was not freed on interpreter shutdown.
3335
Georg Brandl5a7eca12010-03-21 19:29:04 +00003336- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003337 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003338
Georg Brandl3ee81df2008-05-17 18:14:43 +00003339- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3340 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003341 to compact the internal free lists of pre-allocted ints and floats.
3342
Georg Brandl3ee81df2008-05-17 18:14:43 +00003343- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3344 calls. Python expected the return type int but the fork familie
3345 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003346
Georg Brandl3ee81df2008-05-17 18:14:43 +00003347- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3348 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003349
Georg Brandl3ee81df2008-05-17 18:14:43 +00003350- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3351 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003352
Georg Brandl3ee81df2008-05-17 18:14:43 +00003353- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3354 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003355
Georg Brandl3ee81df2008-05-17 18:14:43 +00003356- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3357 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003358
Georg Brandl3ee81df2008-05-17 18:14:43 +00003359- Patch #1473257: generator objects gain a gi_code attribute. This is
3360 the same object as the func_code attribute of the function that
3361 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003362
Georg Brandl3ee81df2008-05-17 18:14:43 +00003363- Issue #1920: "while 0" statements were completely removed by the
3364 compiler, even in the presence of an "else" clause, which is
3365 supposed to be run when the condition is false. Now the compiler
3366 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003367
Guido van Rossumeead05f2008-01-24 18:21:02 +00003368- A few crashers fixed: weakref_in_del.py (issue #1377858);
3369 loosing_dict_ref.py (issue #1303614, test67.py);
3370 borrowed_ref_[34].py (not in tracker).
3371
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003372- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003373 suppressed while an extension is loaded by calling SetErrorMode in
3374 dynload_win.c. The error is still reported properly.
3375
Georg Brandl3ee81df2008-05-17 18:14:43 +00003376- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003377 several extension methods and modules do not work without unicode
3378 support.
3379
Georg Brandl26543b12008-01-21 18:36:51 +00003380- Issue #1882: when compiling code from a string, encoding cookies in the
3381 second line of code were not always recognized correctly.
3382
Georg Brandl14404b62008-01-19 19:27:05 +00003383- Issue #1679: "0x" was taken as a valid integer literal.
3384
Georg Brandl6caad7d2008-01-26 14:19:22 +00003385- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003386 added.
3387
Christian Heimesc94e2b52008-01-14 04:13:37 +00003388- sys.float_info / PyFloat_GetInfo: The floating point information
3389 object was converted from a dict to a specialized structseq object.
3390
Georg Brandl3ee81df2008-05-17 18:14:43 +00003391- Patch #1816: Added sys.flags structseq. It exposes the status of
3392 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003393
Georg Brandl3ee81df2008-05-17 18:14:43 +00003394- Objects/structseq.c: Implemented new structseq representation. The
3395 patch makes structseqs (e.g. the return value of os.stat) more
3396 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003397
Georg Brandl3ee81df2008-05-17 18:14:43 +00003398- Patch #1700288: added a type attribute cache that caches method
3399 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003400
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003401- Bug #1776: __import__() no longer accepts filenames on any platform.
3402 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003403
Georg Brandlaed6c662008-01-07 17:25:53 +00003404- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3405
Georg Brandl3ee81df2008-05-17 18:14:43 +00003406- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3407 envvar and sys.dont_write_bytecode attribute. All these can be set
3408 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003409
Georg Brandl3ee81df2008-05-17 18:14:43 +00003410- Improve some exception messages when Windows fails to load an
3411 extension module. Now we get for example '%1 is not a valid Win32
3412 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003413
Georg Brandl3ee81df2008-05-17 18:14:43 +00003414- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003416- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3417 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003418
Christian Heimes0a8143f2007-12-18 23:22:54 +00003419- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003420 and INF. float("nan"), float("inf") and float("-inf") now work on
3421 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003422
Georg Brandl3ee81df2008-05-17 18:14:43 +00003423- Compiler now generates simpler and faster code for dictionary
3424 literals. The oparg for BUILD_MAP now indicates an estimated
3425 dictionary size. There is a new opcode, STORE_MAP, for adding
3426 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003427
Georg Brandl3ee81df2008-05-17 18:14:43 +00003428- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003433- Issue #1538: Avoid copying string in split/rsplit if the split char
3434 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003435
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003436- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003437 SystemError.
3438
Nick Coghlanef01d822007-12-03 12:55:17 +00003439- PEP 366: Allow explicit relative imports when executing modules
3440 inside packages with the -m switch via a new module level
3441 __package__ attribute.
3442
Georg Brandl3ee81df2008-05-17 18:14:43 +00003443- Issue #1402: Fix a crash on exit, when another thread is still
3444 running, and if the deallocation of its frames somehow calls the
3445 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003446

Georg Brandl3ee81df2008-05-17 18:14:43 +00003460- Issue #1265: Fix a problem with sys.settrace, if the tracing
3461 function uses a generator expression when at the same time the
3462 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003463
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003464- sets and frozensets now have an isdisjoint() method.
3465
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003466- optimize the performance of builtin.sum().
3467
Neal Norwitz44f326e2007-10-05 05:29:17 +00003468- Fix warnings found by the new version of the Coverity checker.
3469
Georg Brandl5a7eca12010-03-21 19:29:04 +00003470- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003471 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3472 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003473
Georg Brandl3ee81df2008-05-17 18:14:43 +00003474- Issue #1686386: Tuple's tp_repr did not take into account the
3475 possibility of having a self-referential tuple, which is possible
3476 from C code. Nor did object's tp_str consider that a type's tp_str
3477 could do something that could lead to an inifinite recursion.
3478 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3479 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003480
Georg Brandl3ee81df2008-05-17 18:14:43 +00003481- Issue #1164: It was possible to trigger deadlock when using the
3482 'print' statement to write to a file since the GIL was not released
3483 as needed. Now PyObject_Print() does the right thing along with
3484 various tp_print implementations of the built-in types and those in
3485 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003486
Georg Brandl3ee81df2008-05-17 18:14:43 +00003487- Issue #1147: Exceptions were directly allowing string exceptions in
3488 their throw() method even though string exceptions no longer
3489 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003490

Brett Cannon1e534b52007-09-07 04:18:30 +00003494- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003495 PyObject_Call() never calling back out to Python code to trigger
3496 recursion depth updates/checks. Required the creation of a static
3497 RuntimeError instance in case normalizing an exception put the

Neal Norwitz0ac60192007-05-27 04:08:54 +00003514- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003515 __*__ attributes. (Some already existed, e.g., __doc__ and
3516 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003517
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003518- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00003525 "except E as target:". This is to provide forwards compatibility
3526 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003527
Brett Cannon229cee22007-05-05 01:34:02 +00003528- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003533- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003534 setting a plain string, ie don't expand to single letter identifiers.
3535
Raymond Hettinger13936692007-04-11 18:40:58 +00003536- Request #1191699: Slices can now be pickled.

3546
Guido van Rossum143b5642007-03-23 04:58:42 +00003547- Bug #1683368: The object.__init__() and object.__new__() methods are
3548 now stricter in rejecting excess arguments. The only time when
3549 either allows excess arguments is when it is not overridden and the
3550 other one is. For backwards compatibility, when both are
3551 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003552 warning later). Also, type.__init__() insists on the same signature
3553 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003554
Georg Brandl3ee81df2008-05-17 18:14:43 +00003555- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3556 object to complex using its __complex__() method before falling back
3557 to the __float__() method. Therefore, the functions in the cmath
3558 module now can operate on objects that define a __complex__()
3559 method.

3576
Georg Brandl7b9c5552007-03-12 14:30:05 +00003577- Bug #1678647: write a newline after printing an exception in any
3578 case, even when converting the value to a string failed.
3579
Georg Brandl871f1bc2007-03-12 13:17:36 +00003580- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003581 its argument, if it exists. If not, it will work like before. This
3582 allows customizing the output of dir() in the presence of a
3583 __getattr__().

3593 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003594
Georg Brandlaa2321b2007-03-07 00:40:28 +00003595- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003596 makes the filenames the warning module prints much more sensible
3597 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003598

Georg Brandl0fca97a2007-03-05 22:28:08 +00003610- Patch #1674228: when assigning a slice (old-style), check for the
3611 sq_ass_slice instead of the sq_slice slot.
3612
Georg Brandl3ee81df2008-05-17 18:14:43 +00003613- When printing an unraisable error, don't print exceptions. before

4241 accepted in TestSuite.addTest(). This should cause no
4242 incompatibility since it never made sense with ordinary subclasses
4243 -- the failure just occurred later, with a more cumbersome
4244 exception.

4528 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004529
Georg Brandl3ee81df2008-05-17 18:14:43 +00004530- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004531 that the SMTP.starttls() caller no longer needs to call ehlo()
4532 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004533 does not claim to support starttls. Adds the
4534 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4615 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4616 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004633 time so that opening a database previously created with the DB_DUP
4634 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4635 opens. Specifically: dictionary assignment to a DB object will
4636 replace all values for a given key when the database allows
4637 duplicate values. DB users should use DB.put(k, v) when they want
4638 to store duplicates; not DB[k] = v.

4645 characters with ASCII value less than 32. Also, it correctly quotes
4646 dots only if they occur on a single line, as opposed to the previous
4647 behavior of quoting dots if they are the second character of any
4648 line.

Neal Norwitz92422fb2006-08-18 03:57:54 +00004970C API
4971-----
4972
Georg Brandl3ee81df2008-05-17 18:14:43 +00004973- Unified naming convention for free lists and their limits. All free
4974 lists in Object/ are named ``free_list``, the counter ``numfree``
4975 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4976 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004977
Georg Brandl3ee81df2008-05-17 18:14:43 +00004978- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4979 to ``PyTuple_SetItem``, it can be used to populate a brand new
4980 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004981
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004982- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004983
Georg Brandl3ee81df2008-05-17 18:14:43 +00004984- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4985 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4986 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004987
4988- Patch #1720595: add T_BOOL to the range of structmember types.
4989
4990- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4991 ``PyFloat_GetInfo()`` to the float API.
4992
Georg Brandl3ee81df2008-05-17 18:14:43 +00004993- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4994 of w# format code incorrectly truncated the length to an int, even
4995 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4996 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004997
Georg Brandl3ee81df2008-05-17 18:14:43 +00004998- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4999 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005000
Georg Brandl3ee81df2008-05-17 18:14:43 +00005001- PEP 3123: Provide forward compatibility with Python 3.0, while
5002 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5003 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005004
Georg Brandl3ee81df2008-05-17 18:14:43 +00005005- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5006 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005007
5008- Patch #1733960: Allow T_LONGLONG to accept ints.
5009
5010- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5011
Christian Heimes000a0742008-01-03 22:16:32 +00005012- Added a new API function ``PyImport_ImportModuleNoBlock``.
5013
Georg Brandl6caad7d2008-01-26 14:19:22 +00005014- Bug #1637022: Prefix AST symbols with _Py_.
5015
5016- Fix some leftovers from the conversion from int to Py_ssize_t
5017 (relevant to strings and sequences of more than 2**31 items).
5018
5019- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5020 outside of pystate.c and should not be necessary.
5021
Georg Brandl3ee81df2008-05-17 18:14:43 +00005022- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5023 absolute imports. In earlier versions they might have used relative
5024 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005025
Georg Brandl3ee81df2008-05-17 18:14:43 +00005026- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5027 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005028
Georg Brandl3ee81df2008-05-17 18:14:43 +00005029- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5030 macro so it can be used as an expression.

5035
Georg Brandl3ee81df2008-05-17 18:14:43 +00005036- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5037 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5038 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5039 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005040
Georg Brandl3ee81df2008-05-17 18:14:43 +00005041- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
5042 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005054- Removed the macfs module. It had been deprecated since Python 2.5.
5055 This lead to the deprecation of macostools.touched() as it relied
5056 solely on macfs and was a no-op under OS X.
