1807What's New in Python 2.6.1
1808==========================
1809
1810*Release date: 04-Dec-2008*
1811
1812Core and Builtins
1813-----------------
1814
1815- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1816 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1817 instead of throwing a MemoryError.
1818
1819- Issue #4367: Python would segfault during compiling when the unicodedata
1820 module couldn't be imported and \N escapes were present.
1821
1822- Issue #4348: Some bytearray methods returned that didn't cause any change to
1823 the bytearray, returned the same bytearray instead of a copy.
1824
1825- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1826
1827- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1828
1829- Issue #4048: The parser module now correctly validates relative imports.
1830
1831- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1832 exec statement.
1833
1834- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1835 method does not return iterators for the 4th and 5th items.
1836
1837- Issue #4209: Enabling unicode_literals and the print_function in the same
1838 __future__ import didn't work.
1839
1840- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1841 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1842 really executed because I cannot move to such directory on win2k)
1843
1844- Issue #4069: When set.remove(element) is used with a set element, the element
1845 is temporarily replaced with an equivalent frozenset. But the eventual
1846 KeyError would always report the empty frozenset([]) as the missing key. Now
1847 it correctly refers to the initial element.
1848
1849- Fixed C99 style comments in several files. Python is now C89 compatible
1850 again.
1851

1998
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001999- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2000 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2001 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2002 ``printf`` function, whereas PyString_FromFormat has an independent
2003 implementation and uses "%zd" on all platforms for size_t values.
2004 This makes a difference on win64, where ``printf`` needs "%Id" to display
2005 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002022 was correctly parsed but parsing of subsequent arguments failed.
2023
Vinay Sajip35e3b032008-09-01 14:33:59 +00002024- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002025 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2026 mechanism. In the process, fix a bug where isinstance() and issubclass(),

2028 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2029 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002165What's New in Python 2.6 beta 3?
2166================================
2167
Barry Warsaw07a4a382008-08-21 01:15:08 +00002168*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002169
2170Core and Builtins
2171-----------------
2172
Guido van Rossumf8402962008-08-20 15:01:50 +00002173- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2174 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2175 extensions do not automatically benefit from the class attribute
2176 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2177 to their tp_flags field if they care. This is a backwards
2178 compatibility feature; in 3.0, all types will use the cache by
2179 default.
2180
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002181- Keyword arguments can now follow starred arguments. (``f(a, *args,
2182 keyword=23)`` is now valid syntax.)
2183
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002184- ctypes function pointers that are COM methods have a boolean True
2185 value again.
2186
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002187- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2188 by denying s# to parse objects that have a releasebuffer procedure,
2189 and introducing s*.
2190
Georg Brandl1e13ea92008-08-11 09:07:59 +00002191- Issue #3537: Fix an assertion failure when an empty but presized dict
2192 object was stored in the freelist.
2193
Mark Dickinsonb6467572008-08-04 21:30:09 +00002194- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2195 ValueError consistently across platforms.
2196
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002197- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2198 (64bit Unix, for example), unichr() would truncate its argument and return
2199 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2200
Neal Norwitze7d8be82008-07-31 17:17:14 +00002201- Apply security patches from Apple.
2202
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002203- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2204 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2205
Antoine Pitrou92f82162008-07-25 22:22:08 +00002206- Issue #1819: function calls with several named parameters are now on
2207 average 35% faster (as measured by pybench).
2208
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002209- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2210 the python debugger steps into a class statement: the free variables (local
2211 variables defined in an outer scope) would be deleted from the outer scope.
2212
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002213- Issue #2620: Overflow checking when allocating or reallocating memory
2214 was not always being done properly in some python types and extension
2215 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2216 all been updated to perform better checks and places in the code that
2217 would previously leak memory on the error path when such an allocation
2218 failed have been fixed.
2219
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002220Library
2221-------
2222
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002223- Issue #3612: Added some missing basic types in ctypes.wintypes.
2224
Benjamin Petersone977ad42008-08-20 01:42:01 +00002225- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2226 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2227
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002228- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2229 version reported by these tools does not necessarily follow the python
2230 version numbering scheme, so the module is less strict when parsing it.
2231
Nick Coghlanf70385a2008-08-18 12:42:46 +00002232- Issue #2235: Added Py3k warnings for types which will become unhashable
2233 under the stricter __hash__ inheritance rules in 3.0. Several types
2234 which did not meet the rules for hash invariants and were already
2235 unhashable in 3.0 have now been explicitly flagged as unhashable in
2236 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2237 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2238
Brett Cannon88f801d2008-08-18 00:46:22 +00002239- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2240 imported into the module but exposed as part of the module's API.
2241
Brett Cannon7b96f072008-08-18 00:41:11 +00002242- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2243
Brett Cannon46225e72008-08-18 00:36:52 +00002244- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2245
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002246- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2247
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002248- Issue #3575: Incremental decoder's decode function now takes bytearray
2249 by using 's*' instead of 't#'.
2250
Jesus Cea585ad8a2009-07-02 15:37:21 +00002251- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002252 fails unicode conversion on 2nd parameter. (windows only)
2253
Georg Brandl21896072010-08-01 22:31:28 +00002254- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00002255 in a redirect.
2256
Brett Cannonabe423e2008-08-16 21:47:07 +00002257- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002258 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002259
Facundo Batistaeb90b782008-08-16 14:44:07 +00002260- Issue #2776: fixed small issue when handling an URL with double slash
2261 after a 302 response in the case of not going through a proxy.
2262
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002263- Issue #2676: in the email package, content-type parsing was hanging on
2264 pathological input because of quadratic or exponential behaviour of a
2265 regular expression.
2266
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002267- Issue #3476: binary buffered reading through the new "io" library is now
2268 thread-safe.
2269
Brett Cannonbf3157b2008-08-14 05:00:03 +00002270- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2271 since mimetools itself is deprecated. Because modules are cached, all
2272 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2273
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002274- Issue #3134: shutil referenced undefined WindowsError symbol.
2275
Robert Schuppenies14646332008-08-10 11:01:53 +00002276- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2277 menu entries were not deleted.
2278
Brett Cannon83e81842008-08-09 23:30:55 +00002279- Copied the implementation of reduce() to _functools.reduce() to have a
2280 version that did not raise a DeprecationWarning under -3.
2281
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002282- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2283 a MemoryError rather than silently stop the iteration.
2284
Guido van Rossum59ce9012008-08-09 14:55:34 +00002285- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2286 to _sre.compile() will now be rejected. This should not affect anybody
2287 since the re.compile() function never generates invalid re-bytecode.
2288
Skip Montanaroa032bf42008-08-08 22:52:51 +00002289- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2290 upon first access it can be automatically initialized from the csv file if
2291 it wasn't initialized during instantiation.
2292
Brett Cannon3aa2a492008-08-06 22:28:09 +00002293- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2294 the reload() built-in has been removed.
2295
Brett Cannon7e30b672008-08-04 21:52:25 +00002296- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002297 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00002298 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
2299 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
2300 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
2301 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2302 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002303
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002304- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2305 raised an AttributeError.
2306
Benjamin Peterson01a24322008-07-28 23:35:27 +00002307- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002308 asking for a specific length. This problem only affected files opened
2309 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002310
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002311- Issue #3449: Update decimal module to use most recent specification
2312 (v. 1.68) and tests (v. 2.58) from IBM.
2313
Georg Brandl21896072010-08-01 22:31:28 +00002314- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002315

2318
Georg Brandlf9efabb2008-07-23 15:16:45 +00002319- Deprecate the "ast" parser function aliases.
2320
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002321- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
2322
2323- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2324 invalid arguments.
2325
2326- Issue #3302: Fix several crashes when calling locale's gettext functions
2327 with None arguments.
2328

2333
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002334- Issue #3394: zipfile.writestr sets external attributes when passed a
2335 file name rather than a ZipInfo instance, so files are extracted with
2336 mode 0600 rather than 000 under Unix.
2337
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002338- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2339 argument in python 2.5, this broke code that subclassed Popen to include its
2340 own poll method. Fixed my moving _deadstate to an _internal_poll method.
2341
Martin v. Löwis8dbf3642008-08-01 14:10:26 +00002342Build
2343-----

2348-------------
2349
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002350- Issue #2235: the C API function PyObject_HashNotImplemented and its
2351 interaction with the tp_hash slot (added in 2.6b2) are now documented
2352
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002353- Issue #643841: The language reference now provides more detailed
2354 coverage of the lookup process for special methods. The disclaimers
2355 regarding lack of coverage of new-style classes have also been
2356 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002359What's New in Python 2.6 beta 2?
2360================================
2361
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002362*Release date: 17-Jul-2008*
2363
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002364Core and Builtins
2365-----------------
2366
Georg Brandl3e483f62008-07-16 22:57:41 +00002367- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2368 its methods now allow for items objects that can be converted to
2369 an integer using operator.index().
2370
Mark Dickinson64b7e502008-07-16 09:40:03 +00002371- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2372 produced a ValueError instead of giving the correct float.
2373
Eric Smitha5fa5a22008-07-16 00:11:49 +00002374- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2375 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2376
Mark Dickinson7103aa42008-07-15 19:08:33 +00002377- Issue #3008: the float type has a new instance method 'float.hex'
2378 and a new class method 'float.fromhex' to convert floating-point
2379 numbers to and from hexadecimal strings, respectively.
2380
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002381- Issue #2235: __hash__ is once again inherited by default. To allow
2382 collections.Hashable to remain meaningful in the presence of the
2383 default hash implementation (object.__hash__), it is now possible
2384 to explicit block inheritance of hash by setting __hash__=None at
2385 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2386 level.
2387
Nick Coghlanb028f502008-07-13 14:52:36 +00002388- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2389 the parent module cannot be found while performing an absolute import.
2390 This means that an incorrectly defined __package__ attribute will
2391 now only prevent relative imports in that module rather than causing
2392 all imports from that module to fail.
2393
Nick Coghlan14ff9942008-07-08 14:21:42 +00002394- Issue #2517: Allow unicode messages in Exceptions again by correctly
2395 bypassing the instance dictionary when looking up __unicode__ on
2396 new-style classes.
2397
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002398- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2399 set to a custom object whose write() method happens to install
2400 another file in sys.stdout.
2401
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002402- Issue #3088: Corrected a race condition in classes derived from
2403 threading.local: the first member set by a thread could be saved in
2404 another thread's dictionary.
2405
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002406- Issue #3004: Minor change to slice.indices(): the start and stop
2407 arguments are now treated identically, making the behaviour easier
2408 to describe and understand. For example, slice(None, -10,
2409 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2410 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2411 10, -1).
2412
Georg Brandl278fc502008-07-19 12:46:12 +00002413- Issue #3219: Calling a function with repeated keyword arguments,
2414 f(a=2, a=23), would not cause a syntax error. This was a regression
2415 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002416
Georg Brandl278fc502008-07-19 12:46:12 +00002417- Issue #2862: Make int and float freelist management consistent with
2418 other freelists. Changes their CompactFreeList apis into
2419 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002420

2422-------
2423
Thomas Heller57adf222008-08-14 19:10:48 +00002424- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2425 api functions without holding the GIL, which could lead to a fatal
2426 error when they failed.
2427
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002428- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002436- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2437 ForkingPickler.register() to resolve conflict with ctypes.
2438
Vinay Sajip51e65192008-07-18 09:01:10 +00002439- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

2442 a valid dlerror() message.
2443
Thomas Heller2bad6572008-07-15 17:19:50 +00002444- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2445 incomplete structure was created.
2446
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002447- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00002449- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2450

2862
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002863- On MacOS X it is now possible to install the framework in 64-bit
2864 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002865 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002866
2867 This is controlled by the configure argument ``--with-universal-archs``:
2868
2869 - ``--with-universal-archs=all``: install 4-way universal
2870
2871 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2872
2873 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2874
2875 This option should be used in combination with ``--enable-universalsdk=``.
2876
2877 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

2914 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00002915
Christian Heimese74c8f22008-04-19 02:23:57 +00002916- Added kill, terminate and send_signal(sig) to subprocess.Popen.
2917
Georg Brandl3ee81df2008-05-17 18:14:43 +00002918- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
2919 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00002920

Georg Brandl3ee81df2008-05-17 18:14:43 +00002927- Issue #1631171: Re-implement the 'warnings' module in C (the
2928 original Python code has been kept as backup). This will allow for
2929 using the 'warning's machinery in such places as the parser where
2930 use of pure Python code is not possible. Both the ``showarning()``
2931 and ``formatwarning()`` gain an optional 'line' argument which is
2932 not called by default for backwards-compatibility reasons. Setting
2933 ``warnings.showwarning()`` to an implementation that lacks support
2934 for the ``line`` argument will raise a DeprecationWarning.

Thomas Hellerbf027c42008-04-24 18:14:19 +00002957 reference to themselves.
2958
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002959- The getpass module has been improved on Unix. It now uses /dev/tty
2960 by default and uses stderr instead of stdout. A GetPassWarning is
2961 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002962

Georg Brandl3ee81df2008-05-17 18:14:43 +00002976- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002977 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002997- Issue #2550: The approach used by client/server code for obtaining
2998 ports to listen on in network-oriented tests has been refined in an
2999 effort to facilitate running multiple instances of the entire
3000 regression test suite in parallel without issue.
3001 test_support.bind_port() has been fixed such that it will always
3002 return a unique port -- which wasn't always the case with the
3003 previous implementation, especially if socket options had been set
3004 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3005 new implementation of bind_port() will actually raise an exception
3006 if it is passed an AF_INET/SOCK_STREAM socket with either the
3007 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3008 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3009 the socket it's been passed. This currently only applies to
3010 Windows. This option prevents any other sockets from binding to the
3011 host/port we've bound to, thus removing the possibility of the
3012 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3013 when a second SOCK_STREAM socket binds and accepts to a host/port
3014 that's already been bound by another socket. The optional preferred
3015 port parameter to bind_port() has been removed. Under no
3016 circumstances should tests be hard coding ports!
3017
3018 test_support.find_unused_port() has also been introduced, which will
3019 pass a temporary socket object to bind_port() in order to obtain an
3020 unused port. The temporary socket object is then closed and
3021 deleted, and the port is returned. This method should only be used
3022 for obtaining an unused port in order to pass to an external program
3023 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3024 a parameter to a server-oriented class that doesn't give you direct
3025 access to the underlying socket used.
3026
3027 Finally, test_support.HOST has been introduced, which should be used
3028 for the host argument of any relevant socket calls (i.e. bind and
3029 connect).

3304-----------------
3305
Fred Drakea8ee94b2008-03-01 02:45:07 +00003306- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003307 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003308
Georg Brandlad61bc82008-02-23 15:11:18 +00003309- Issue #2067: file.__exit__() now calls subclasses' close() method.
3310
3311- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003312
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003313- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl21896072010-08-01 22:31:28 +00003314 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00003315
Eric Smitha73fbe72008-02-23 03:09:44 +00003316- Added the future_builtins module, which contains hex() and oct().
3317 These are the PEP 3127 version of these functions, designed to be
3318 compatible with the hex() and oct() builtins from Python 3.0. They
3319 differ slightly in their output formats from the existing, unchanged
3320 Python 2.6 builtins. The expected usage of the future_builtins
3321 module is:
3322 from future_builtins import hex, oct
3323
Eric Smith7ef40bf2008-02-20 23:34:22 +00003324- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3325 exponents for exponents with absolute value < 100. Follows C99
3326 standard. This is a change on Windows, which would use 3 digits.
3327 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3328 so that any alterations it does to the resulting string will be
3329 available in stringlib/formatter.h (for float.__format__).
3330
Eric Smith5a3c1352008-02-19 13:21:56 +00003331- Implemented PEP 3101, Advanced String Formatting. This adds a new
3332 builtin format(); a format() method for str and unicode; a
3333 __format__() method to object, str, unicode, int, long, float, and
3334 datetime; the class string.Formatter; and the C API
3335 PyObject_Format().
3336
Georg Brandl3ee81df2008-05-17 18:14:43 +00003337- Fixed several potential crashes, all caused by specially crafted
3338 __del__ methods exploiting objects in temporarily inconsistent
3339 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003340
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003341- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003342 prevent a possible crash: an Abstract Base Class would try to access
3343 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003344
Georg Brandl3ee81df2008-05-17 18:14:43 +00003345- Fixed repr() and str() of complex numbers with infinity or nan as
3346 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003347
Georg Brandl3ee81df2008-05-17 18:14:43 +00003348- Clear all free lists during a gc.collect() of the highest generation
3349 in order to allow pymalloc to free more arenas. Python may give back
3350 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003351
Georg Brandl3ee81df2008-05-17 18:14:43 +00003352- Issue #2045: Fix an infinite recursion triggered when printing a
3353 subclass of collections.defaultdict, if its default_factory is set
3354 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003355
Christian Heimesf75dbef2008-02-08 00:11:31 +00003356- Fixed a minor memory leak in dictobject.c. The content of the free
3357 list was not freed on interpreter shutdown.
3358
Georg Brandl5a7eca12010-03-21 19:29:04 +00003359- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003360 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003361
Georg Brandl3ee81df2008-05-17 18:14:43 +00003362- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3363 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003364 to compact the internal free lists of pre-allocted ints and floats.
3365
Georg Brandl3ee81df2008-05-17 18:14:43 +00003366- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3367 calls. Python expected the return type int but the fork familie
3368 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003369
Georg Brandl3ee81df2008-05-17 18:14:43 +00003370- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3371 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003372
Georg Brandl3ee81df2008-05-17 18:14:43 +00003373- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3374 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003375
Georg Brandl3ee81df2008-05-17 18:14:43 +00003376- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3377 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003378
Georg Brandl3ee81df2008-05-17 18:14:43 +00003379- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3380 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003381
Georg Brandl3ee81df2008-05-17 18:14:43 +00003382- Patch #1473257: generator objects gain a gi_code attribute. This is
3383 the same object as the func_code attribute of the function that
3384 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003385
Georg Brandl3ee81df2008-05-17 18:14:43 +00003386- Issue #1920: "while 0" statements were completely removed by the
3387 compiler, even in the presence of an "else" clause, which is
3388 supposed to be run when the condition is false. Now the compiler
3389 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003390
Guido van Rossumeead05f2008-01-24 18:21:02 +00003391- A few crashers fixed: weakref_in_del.py (issue #1377858);
3392 loosing_dict_ref.py (issue #1303614, test67.py);
3393 borrowed_ref_[34].py (not in tracker).
3394
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003395- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003396 suppressed while an extension is loaded by calling SetErrorMode in
3397 dynload_win.c. The error is still reported properly.
3398
Georg Brandl3ee81df2008-05-17 18:14:43 +00003399- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003400 several extension methods and modules do not work without unicode
3401 support.
3402
Georg Brandl26543b12008-01-21 18:36:51 +00003403- Issue #1882: when compiling code from a string, encoding cookies in the
3404 second line of code were not always recognized correctly.
3405
Georg Brandl14404b62008-01-19 19:27:05 +00003406- Issue #1679: "0x" was taken as a valid integer literal.
3407
Georg Brandl6caad7d2008-01-26 14:19:22 +00003408- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003409 added.
3410
Christian Heimesc94e2b52008-01-14 04:13:37 +00003411- sys.float_info / PyFloat_GetInfo: The floating point information
3412 object was converted from a dict to a specialized structseq object.
3413
Georg Brandl3ee81df2008-05-17 18:14:43 +00003414- Patch #1816: Added sys.flags structseq. It exposes the status of
3415 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003416
Georg Brandl3ee81df2008-05-17 18:14:43 +00003417- Objects/structseq.c: Implemented new structseq representation. The
3418 patch makes structseqs (e.g. the return value of os.stat) more
3419 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003420
Georg Brandl3ee81df2008-05-17 18:14:43 +00003421- Patch #1700288: added a type attribute cache that caches method
3422 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003423
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003424- Bug #1776: __import__() no longer accepts filenames on any platform.
3425 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003426
Georg Brandlaed6c662008-01-07 17:25:53 +00003427- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3428
Georg Brandl3ee81df2008-05-17 18:14:43 +00003429- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3430 envvar and sys.dont_write_bytecode attribute. All these can be set
3431 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003432
Georg Brandl3ee81df2008-05-17 18:14:43 +00003433- Improve some exception messages when Windows fails to load an
3434 extension module. Now we get for example '%1 is not a valid Win32
3435 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003436
Georg Brandl3ee81df2008-05-17 18:14:43 +00003437- Bug #1481296: Fixed long(float('nan')) != 0L.

3440 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003441
Christian Heimes0a8143f2007-12-18 23:22:54 +00003442- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003443 and INF. float("nan"), float("inf") and float("-inf") now work on
3444 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003445
Georg Brandl3ee81df2008-05-17 18:14:43 +00003446- Compiler now generates simpler and faster code for dictionary
3447 literals. The oparg for BUILD_MAP now indicates an estimated
3448 dictionary size. There is a new opcode, STORE_MAP, for adding
3449 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003450
Georg Brandl3ee81df2008-05-17 18:14:43 +00003451- Issue #1638: %zd configure test fails on Linux.

3481 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003482
Georg Brandl3ee81df2008-05-17 18:14:43 +00003483- Issue #1265: Fix a problem with sys.settrace, if the tracing
3484 function uses a generator expression when at the same time the
3485 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003486
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003487- sets and frozensets now have an isdisjoint() method.
3488

3492
Georg Brandl5a7eca12010-03-21 19:29:04 +00003493- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003494 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3495 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003496
Georg Brandl3ee81df2008-05-17 18:14:43 +00003497- Issue #1686386: Tuple's tp_repr did not take into account the
3498 possibility of having a self-referential tuple, which is possible
3499 from C code. Nor did object's tp_str consider that a type's tp_str
3500 could do something that could lead to an inifinite recursion.
3501 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3502 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003503
Georg Brandl3ee81df2008-05-17 18:14:43 +00003504- Issue #1164: It was possible to trigger deadlock when using the
3505 'print' statement to write to a file since the GIL was not released
3506 as needed. Now PyObject_Print() does the right thing along with
3507 various tp_print implementations of the built-in types and those in
3508 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00003517- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003518 PyObject_Call() never calling back out to Python code to trigger
3519 recursion depth updates/checks. Required the creation of a static
3520 RuntimeError instance in case normalizing an exception put the
3521 recursion check value past its limit. Fixes crashers
3522 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003537- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003538 __*__ attributes. (Some already existed, e.g., __doc__ and
3539 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003540
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003541- Add -3 option to the interpreter to warn about features that are

3545 calls.
3546
Collin Winter62903052007-05-18 23:11:24 +00003547- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003548 "except E as target:". This is to provide forwards compatibility
3549 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003550
Brett Cannon229cee22007-05-05 01:34:02 +00003551- Deprecate BaseException.message as per PEP 352.
3552
Georg Brandl3ee81df2008-05-17 18:14:43 +00003553- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003554 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003556- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003557 setting a plain string, ie don't expand to single letter identifiers.
3558
Raymond Hettinger13936692007-04-11 18:40:58 +00003559- Request #1191699: Slices can now be pickled.
3560
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003561- Request #1193128: str.translate() now allows a None argument for
3562 translations that only remove characters without re-mapping the
3563 remaining characters.
3564
Georg Brandl5cb76c12007-03-21 09:00:39 +00003565- Patch #1682205: a TypeError while unpacking an iterable is no longer

3569
Guido van Rossum143b5642007-03-23 04:58:42 +00003570- Bug #1683368: The object.__init__() and object.__new__() methods are
3571 now stricter in rejecting excess arguments. The only time when
3572 either allows excess arguments is when it is not overridden and the
3573 other one is. For backwards compatibility, when both are
3574 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003575 warning later). Also, type.__init__() insists on the same signature
3576 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003577
Georg Brandl3ee81df2008-05-17 18:14:43 +00003578- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3579 object to complex using its __complex__() method before falling back
3580 to the __float__() method. Therefore, the functions in the cmath
3581 module now can operate on objects that define a __complex__()
3582 method.

3599
Georg Brandl7b9c5552007-03-12 14:30:05 +00003600- Bug #1678647: write a newline after printing an exception in any
3601 case, even when converting the value to a string failed.
3602
Georg Brandl871f1bc2007-03-12 13:17:36 +00003603- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003604 its argument, if it exists. If not, it will work like before. This
3605 allows customizing the output of dir() in the presence of a
3606 __getattr__().

3615 parthensized forms. This means complex(repr(x)) now works instead of
3616 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003617
Georg Brandlaa2321b2007-03-07 00:40:28 +00003618- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003619 makes the filenames the warning module prints much more sensible
3620 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003621

Georg Brandl0fca97a2007-03-05 22:28:08 +00003633- Patch #1674228: when assigning a slice (old-style), check for the
3634 sq_ass_slice instead of the sq_slice slot.
3635
Georg Brandl3ee81df2008-05-17 18:14:43 +00003636- When printing an unraisable error, don't print exceptions. before

4247 Python would crash instead of raising an error.
4248

4264 accepted in TestSuite.addTest(). This should cause no
4265 incompatibility since it never made sense with ordinary subclasses
4266 -- the failure just occurred later, with a more cumbersome
4267 exception.

4550 obtained from the TLS negotiation itself. Patch contributed by Bill
4551 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004552
Georg Brandl3ee81df2008-05-17 18:14:43 +00004553- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004554 that the SMTP.starttls() caller no longer needs to call ehlo()
4555 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004556 does not claim to support starttls. Adds the
4557 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00004656 time so that opening a database previously created with the DB_DUP
4657 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4658 opens. Specifically: dictionary assignment to a DB object will
4659 replace all values for a given key when the database allows
4660 duplicate values. DB users should use DB.put(k, v) when they want
4661 to store duplicates; not DB[k] = v.

4668 characters with ASCII value less than 32. Also, it correctly quotes
4669 dots only if they occur on a single line, as opposed to the previous
4670 behavior of quoting dots if they are the second character of any
4671 line.

4994-----
4995
Georg Brandl3ee81df2008-05-17 18:14:43 +00004996- Unified naming convention for free lists and their limits. All free
4997 lists in Object/ are named ``free_list``, the counter ``numfree``
4998 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4999 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005000
Georg Brandl3ee81df2008-05-17 18:14:43 +00005001- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5002 to ``PyTuple_SetItem``, it can be used to populate a brand new
5003 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005004
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005005- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005007- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5008 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5009 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005010
5011- Patch #1720595: add T_BOOL to the range of structmember types.
5012
5013- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5014 ``PyFloat_GetInfo()`` to the float API.
5015
Georg Brandl3ee81df2008-05-17 18:14:43 +00005016- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5017 of w# format code incorrectly truncated the length to an int, even
5018 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5019 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005020
Georg Brandl3ee81df2008-05-17 18:14:43 +00005021- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5022 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005023
Georg Brandl3ee81df2008-05-17 18:14:43 +00005024- PEP 3123: Provide forward compatibility with Python 3.0, while
5025 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5026 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005027
Georg Brandl3ee81df2008-05-17 18:14:43 +00005028- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5029 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005030
5031- Patch #1733960: Allow T_LONGLONG to accept ints.
5032
5033- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5034
Christian Heimes000a0742008-01-03 22:16:32 +00005035- Added a new API function ``PyImport_ImportModuleNoBlock``.

5038
5039- Fix some leftovers from the conversion from int to Py_ssize_t
5040 (relevant to strings and sequences of more than 2**31 items).
5041
5042- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5043 outside of pystate.c and should not be necessary.
5044
Georg Brandl3ee81df2008-05-17 18:14:43 +00005045- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5046 absolute imports. In earlier versions they might have used relative
5047 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005048
Georg Brandl3ee81df2008-05-17 18:14:43 +00005049- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5050 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005051
Georg Brandl3ee81df2008-05-17 18:14:43 +00005052- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5053 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005059- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5060 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5061 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5062 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005063
Georg Brandl3ee81df2008-05-17 18:14:43 +00005064- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005077- Removed the macfs module. It had been deprecated since Python 2.5.
5078 This lead to the deprecation of macostools.touched() as it relied
5079 solely on macfs and was a no-op under OS X.
