1804What's New in Python 2.6.1
1805==========================
1806
1807*Release date: 04-Dec-2008*
1808
1809Core and Builtins
1810-----------------
1811
1812- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1813 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1814 instead of throwing a MemoryError.
1815
1816- Issue #4367: Python would segfault during compiling when the unicodedata
1817 module couldn't be imported and \N escapes were present.
1818
1819- Issue #4348: Some bytearray methods returned that didn't cause any change to
1820 the bytearray, returned the same bytearray instead of a copy.
1821
1822- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1823
1824- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1825
1826- Issue #4048: The parser module now correctly validates relative imports.
1827
1828- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1829 exec statement.
1830
1831- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1832 method does not return iterators for the 4th and 5th items.
1833
1834- Issue #4209: Enabling unicode_literals and the print_function in the same
1835 __future__ import didn't work.
1836
1837- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1838 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1839 really executed because I cannot move to such directory on win2k)
1840
1841- Issue #4069: When set.remove(element) is used with a set element, the element
1842 is temporarily replaced with an equivalent frozenset. But the eventual
1843 KeyError would always report the empty frozenset([]) as the missing key. Now
1844 it correctly refers to the initial element.
1845
1846- Fixed C99 style comments in several files. Python is now C89 compatible
1847 again.
1848

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001994- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1995
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001996- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1997 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1998 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1999 ``printf`` function, whereas PyString_FromFormat has an independent
2000 implementation and uses "%zd" on all platforms for size_t values.
2001 This makes a difference on win64, where ``printf`` needs "%Id" to display
2002 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002019 was correctly parsed but parsing of subsequent arguments failed.
2020
Vinay Sajip35e3b032008-09-01 14:33:59 +00002021- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002022 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2023 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2024 when given a tuple of classes as second argument, were looking up
2025 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2026 type object.

Guido van Rossumf8402962008-08-20 15:01:50 +00002170- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2171 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2172 extensions do not automatically benefit from the class attribute
2173 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2174 to their tp_flags field if they care. This is a backwards
2175 compatibility feature; in 3.0, all types will use the cache by
2176 default.
2177
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002178- Keyword arguments can now follow starred arguments. (``f(a, *args,
2179 keyword=23)`` is now valid syntax.)
2180
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002181- ctypes function pointers that are COM methods have a boolean True
2182 value again.
2183
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002184- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2185 by denying s# to parse objects that have a releasebuffer procedure,
2186 and introducing s*.
2187
Georg Brandl1e13ea92008-08-11 09:07:59 +00002188- Issue #3537: Fix an assertion failure when an empty but presized dict
2189 object was stored in the freelist.
2190
Mark Dickinsonb6467572008-08-04 21:30:09 +00002191- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2192 ValueError consistently across platforms.
2193
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002194- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2195 (64bit Unix, for example), unichr() would truncate its argument and return
2196 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2197
Neal Norwitze7d8be82008-07-31 17:17:14 +00002198- Apply security patches from Apple.
2199
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002200- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2201 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2202
Antoine Pitrou92f82162008-07-25 22:22:08 +00002203- Issue #1819: function calls with several named parameters are now on
2204 average 35% faster (as measured by pybench).
2205
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002206- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2207 the python debugger steps into a class statement: the free variables (local
2208 variables defined in an outer scope) would be deleted from the outer scope.
2209
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002210- Issue #2620: Overflow checking when allocating or reallocating memory
2211 was not always being done properly in some python types and extension
2212 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2213 all been updated to perform better checks and places in the code that
2214 would previously leak memory on the error path when such an allocation
2215 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002220- Issue #3612: Added some missing basic types in ctypes.wintypes.
2221
Benjamin Petersone977ad42008-08-20 01:42:01 +00002222- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2223 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2224
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002225- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2226 version reported by these tools does not necessarily follow the python
2227 version numbering scheme, so the module is less strict when parsing it.
2228
Nick Coghlanf70385a2008-08-18 12:42:46 +00002229- Issue #2235: Added Py3k warnings for types which will become unhashable
2230 under the stricter __hash__ inheritance rules in 3.0. Several types
2231 which did not meet the rules for hash invariants and were already
2232 unhashable in 3.0 have now been explicitly flagged as unhashable in
2233 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2234 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2235
Brett Cannon88f801d2008-08-18 00:46:22 +00002236- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2237 imported into the module but exposed as part of the module's API.
2238
Brett Cannon7b96f072008-08-18 00:41:11 +00002239- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2240
Brett Cannon46225e72008-08-18 00:36:52 +00002241- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2242
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002243- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2244
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002245- Issue #3575: Incremental decoder's decode function now takes bytearray
2246 by using 's*' instead of 't#'.
2247
Jesus Cea585ad8a2009-07-02 15:37:21 +00002248- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002249 fails unicode conversion on 2nd parameter. (windows only)
2250
Georg Brandl21896072010-08-01 22:31:28 +00002251- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00002252 in a redirect.
2253
Brett Cannonabe423e2008-08-16 21:47:07 +00002254- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002255 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002256
Facundo Batistaeb90b782008-08-16 14:44:07 +00002257- Issue #2776: fixed small issue when handling an URL with double slash
2258 after a 302 response in the case of not going through a proxy.
2259
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002260- Issue #2676: in the email package, content-type parsing was hanging on
2261 pathological input because of quadratic or exponential behaviour of a
2262 regular expression.
2263
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002264- Issue #3476: binary buffered reading through the new "io" library is now
2265 thread-safe.
2266
Brett Cannonbf3157b2008-08-14 05:00:03 +00002267- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2268 since mimetools itself is deprecated. Because modules are cached, all
2269 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2270
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002271- Issue #3134: shutil referenced undefined WindowsError symbol.
2272
Robert Schuppenies14646332008-08-10 11:01:53 +00002273- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2274 menu entries were not deleted.
2275
Brett Cannon83e81842008-08-09 23:30:55 +00002276- Copied the implementation of reduce() to _functools.reduce() to have a
2277 version that did not raise a DeprecationWarning under -3.
2278
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002279- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2280 a MemoryError rather than silently stop the iteration.
2281
Guido van Rossum59ce9012008-08-09 14:55:34 +00002282- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2283 to _sre.compile() will now be rejected. This should not affect anybody
2284 since the re.compile() function never generates invalid re-bytecode.
2285
Skip Montanaroa032bf42008-08-08 22:52:51 +00002286- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2287 upon first access it can be automatically initialized from the csv file if
2288 it wasn't initialized during instantiation.
2289
Brett Cannon3aa2a492008-08-06 22:28:09 +00002290- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2291 the reload() built-in has been removed.
2292
Brett Cannon7e30b672008-08-04 21:52:25 +00002293- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002294 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2302 raised an AttributeError.
2303
Benjamin Peterson01a24322008-07-28 23:35:27 +00002304- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002305 asking for a specific length. This problem only affected files opened
2306 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002307
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002308- Issue #3449: Update decimal module to use most recent specification
2309 (v. 1.68) and tests (v. 2.58) from IBM.
2310
Georg Brandl21896072010-08-01 22:31:28 +00002311- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002312
Georg Brandl21896072010-08-01 22:31:28 +00002313- Issue #1592: Improve error reporting when operations are attempted
Raymond Hettinger8c664e82008-07-25 18:43:33 +00002314 on a closed shelf.
2315
Georg Brandlf9efabb2008-07-23 15:16:45 +00002316- Deprecate the "ast" parser function aliases.
2317
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002318- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
2319
2320- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2321 invalid arguments.
2322
2323- Issue #3302: Fix several crashes when calling locale's gettext functions
2324 with None arguments.
2325
2326- Issue #3389: Allow resolving dotted names for handlers in logging
2327 configuration files.
2328
2329- Deprecate the sunaudio module for removal in Python 3.0.
2330
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002331- Issue #3394: zipfile.writestr sets external attributes when passed a
2332 file name rather than a ZipInfo instance, so files are extracted with
2333 mode 0600 rather than 000 under Unix.
2334
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002335- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2336 argument in python 2.5, this broke code that subclassed Popen to include its
2337 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002347- Issue #2235: the C API function PyObject_HashNotImplemented and its
2348 interaction with the tp_hash slot (added in 2.6b2) are now documented
2349
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002350- Issue #643841: The language reference now provides more detailed
2351 coverage of the lookup process for special methods. The disclaimers
2352 regarding lack of coverage of new-style classes have also been
2353 removed, since the coverage is now fairly reasonable.

2357================================
2358
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002359*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002361Core and Builtins
2362-----------------
2363
Georg Brandl3e483f62008-07-16 22:57:41 +00002364- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2365 its methods now allow for items objects that can be converted to
2366 an integer using operator.index().
2367
Mark Dickinson64b7e502008-07-16 09:40:03 +00002368- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2369 produced a ValueError instead of giving the correct float.
2370
Eric Smitha5fa5a22008-07-16 00:11:49 +00002371- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2372 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2373
Mark Dickinson7103aa42008-07-15 19:08:33 +00002374- Issue #3008: the float type has a new instance method 'float.hex'
2375 and a new class method 'float.fromhex' to convert floating-point
2376 numbers to and from hexadecimal strings, respectively.
2377
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002378- Issue #2235: __hash__ is once again inherited by default. To allow
2379 collections.Hashable to remain meaningful in the presence of the
2380 default hash implementation (object.__hash__), it is now possible
2381 to explicit block inheritance of hash by setting __hash__=None at
2382 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2383 level.
2384
Nick Coghlanb028f502008-07-13 14:52:36 +00002385- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2386 the parent module cannot be found while performing an absolute import.
2387 This means that an incorrectly defined __package__ attribute will
2388 now only prevent relative imports in that module rather than causing
2389 all imports from that module to fail.
2390
Nick Coghlan14ff9942008-07-08 14:21:42 +00002391- Issue #2517: Allow unicode messages in Exceptions again by correctly
2392 bypassing the instance dictionary when looking up __unicode__ on
2393 new-style classes.
2394
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002395- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2396 set to a custom object whose write() method happens to install
2397 another file in sys.stdout.
2398
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002399- Issue #3088: Corrected a race condition in classes derived from
2400 threading.local: the first member set by a thread could be saved in
2401 another thread's dictionary.
2402
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002403- Issue #3004: Minor change to slice.indices(): the start and stop
2404 arguments are now treated identically, making the behaviour easier
2405 to describe and understand. For example, slice(None, -10,
2406 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2407 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2408 10, -1).
2409
Georg Brandl278fc502008-07-19 12:46:12 +00002410- Issue #3219: Calling a function with repeated keyword arguments,
2411 f(a=2, a=23), would not cause a syntax error. This was a regression
2412 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002413
Georg Brandl278fc502008-07-19 12:46:12 +00002414- Issue #2862: Make int and float freelist management consistent with
2415 other freelists. Changes their CompactFreeList apis into
2416 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002417

2419-------
2420
Thomas Heller57adf222008-08-14 19:10:48 +00002421- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2422 api functions without holding the GIL, which could lead to a fatal
2423 error when they failed.
2424
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002425- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
2426
Jesse Noller7fb96402008-07-17 21:01:05 +00002427- Issue #3395: fix reference in test_multiprocessing to old debugInfo method

Jesse Noller13e9d582008-07-16 14:32:36 +00002433- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2434 ForkingPickler.register() to resolve conflict with ctypes.
2435
Vinay Sajip51e65192008-07-18 09:01:10 +00002436- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002437
Thomas Heller880f5292008-07-15 19:39:38 +00002438- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2439 a valid dlerror() message.
2440
Thomas Heller2bad6572008-07-15 17:19:50 +00002441- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2442 incomplete structure was created.
2443
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002444- Issue #3339: dummy_thread.acquire() should not return None.
2445
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002446- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2447
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002448- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002449
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002450- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2451 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002452 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002453 content-length. The problem had been corrected in the 2.4 branch, but never
2454 merged into trunk.

2861 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002862 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002863
2864 This is controlled by the configure argument ``--with-universal-archs``:
2865
2866 - ``--with-universal-archs=all``: install 4-way universal
2867
2868 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2869
2870 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2871
2872 This option should be used in combination with ``--enable-universalsdk=``.
2873
2874 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 +00002924- Issue #1631171: Re-implement the 'warnings' module in C (the
2925 original Python code has been kept as backup). This will allow for
2926 using the 'warning's machinery in such places as the parser where
2927 use of pure Python code is not possible. Both the ``showarning()``
2928 and ``formatwarning()`` gain an optional 'line' argument which is
2929 not called by default for backwards-compatibility reasons. Setting
2930 ``warnings.showwarning()`` to an implementation that lacks support
2931 for the ``line`` argument will raise a DeprecationWarning.

2955
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002956- The getpass module has been improved on Unix. It now uses /dev/tty
2957 by default and uses stderr instead of stdout. A GetPassWarning is
2958 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002994- Issue #2550: The approach used by client/server code for obtaining
2995 ports to listen on in network-oriented tests has been refined in an
2996 effort to facilitate running multiple instances of the entire
2997 regression test suite in parallel without issue.
2998 test_support.bind_port() has been fixed such that it will always
2999 return a unique port -- which wasn't always the case with the
3000 previous implementation, especially if socket options had been set
3001 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3002 new implementation of bind_port() will actually raise an exception
3003 if it is passed an AF_INET/SOCK_STREAM socket with either the
3004 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3005 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3006 the socket it's been passed. This currently only applies to
3007 Windows. This option prevents any other sockets from binding to the
3008 host/port we've bound to, thus removing the possibility of the
3009 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3010 when a second SOCK_STREAM socket binds and accepts to a host/port
3011 that's already been bound by another socket. The optional preferred
3012 port parameter to bind_port() has been removed. Under no
3013 circumstances should tests be hard coding ports!
3014
3015 test_support.find_unused_port() has also been introduced, which will
3016 pass a temporary socket object to bind_port() in order to obtain an
3017 unused port. The temporary socket object is then closed and
3018 deleted, and the port is returned. This method should only be used
3019 for obtaining an unused port in order to pass to an external program
3020 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3021 a parameter to a server-oriented class that doesn't give you direct
3022 access to the underlying socket used.
3023
3024 Finally, test_support.HOST has been introduced, which should be used
3025 for the host argument of any relevant socket calls (i.e. bind and
3026 connect).

3301-----------------
3302
Fred Drakea8ee94b2008-03-01 02:45:07 +00003303- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003304 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003305
Georg Brandlad61bc82008-02-23 15:11:18 +00003306- Issue #2067: file.__exit__() now calls subclasses' close() method.
3307
3308- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003309
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003310- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl21896072010-08-01 22:31:28 +00003311 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00003312
Eric Smitha73fbe72008-02-23 03:09:44 +00003313- Added the future_builtins module, which contains hex() and oct().
3314 These are the PEP 3127 version of these functions, designed to be
3315 compatible with the hex() and oct() builtins from Python 3.0. They
3316 differ slightly in their output formats from the existing, unchanged
3317 Python 2.6 builtins. The expected usage of the future_builtins
3318 module is:
3319 from future_builtins import hex, oct
3320
Eric Smith7ef40bf2008-02-20 23:34:22 +00003321- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3322 exponents for exponents with absolute value < 100. Follows C99
3323 standard. This is a change on Windows, which would use 3 digits.
3324 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3325 so that any alterations it does to the resulting string will be
3326 available in stringlib/formatter.h (for float.__format__).
3327
Eric Smith5a3c1352008-02-19 13:21:56 +00003328- Implemented PEP 3101, Advanced String Formatting. This adds a new
3329 builtin format(); a format() method for str and unicode; a
3330 __format__() method to object, str, unicode, int, long, float, and
3331 datetime; the class string.Formatter; and the C API
3332 PyObject_Format().
3333
Georg Brandl3ee81df2008-05-17 18:14:43 +00003334- Fixed several potential crashes, all caused by specially crafted
3335 __del__ methods exploiting objects in temporarily inconsistent
3336 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003337
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003338- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003339 prevent a possible crash: an Abstract Base Class would try to access
3340 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003341
Georg Brandl3ee81df2008-05-17 18:14:43 +00003342- Fixed repr() and str() of complex numbers with infinity or nan as
3343 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003344
Georg Brandl3ee81df2008-05-17 18:14:43 +00003345- Clear all free lists during a gc.collect() of the highest generation
3346 in order to allow pymalloc to free more arenas. Python may give back
3347 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003348
Georg Brandl3ee81df2008-05-17 18:14:43 +00003349- Issue #2045: Fix an infinite recursion triggered when printing a
3350 subclass of collections.defaultdict, if its default_factory is set
3351 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003352
Christian Heimesf75dbef2008-02-08 00:11:31 +00003353- Fixed a minor memory leak in dictobject.c. The content of the free
3354 list was not freed on interpreter shutdown.
3355
Georg Brandl5a7eca12010-03-21 19:29:04 +00003356- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003357 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003358
Georg Brandl3ee81df2008-05-17 18:14:43 +00003359- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3360 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003361 to compact the internal free lists of pre-allocted ints and floats.
3362
Georg Brandl3ee81df2008-05-17 18:14:43 +00003363- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3364 calls. Python expected the return type int but the fork familie
3365 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003366
Georg Brandl3ee81df2008-05-17 18:14:43 +00003367- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3368 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003369
Georg Brandl3ee81df2008-05-17 18:14:43 +00003370- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3371 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003372
Georg Brandl3ee81df2008-05-17 18:14:43 +00003373- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3374 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003375
Georg Brandl3ee81df2008-05-17 18:14:43 +00003376- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3377 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003378
Georg Brandl3ee81df2008-05-17 18:14:43 +00003379- Patch #1473257: generator objects gain a gi_code attribute. This is
3380 the same object as the func_code attribute of the function that
3381 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003382
Georg Brandl3ee81df2008-05-17 18:14:43 +00003383- Issue #1920: "while 0" statements were completely removed by the
3384 compiler, even in the presence of an "else" clause, which is
3385 supposed to be run when the condition is false. Now the compiler
3386 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003387
Guido van Rossumeead05f2008-01-24 18:21:02 +00003388- A few crashers fixed: weakref_in_del.py (issue #1377858);
3389 loosing_dict_ref.py (issue #1303614, test67.py);
3390 borrowed_ref_[34].py (not in tracker).
3391
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003392- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003393 suppressed while an extension is loaded by calling SetErrorMode in
3394 dynload_win.c. The error is still reported properly.
3395
Georg Brandl3ee81df2008-05-17 18:14:43 +00003396- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003397 several extension methods and modules do not work without unicode
3398 support.
3399
Georg Brandl26543b12008-01-21 18:36:51 +00003400- Issue #1882: when compiling code from a string, encoding cookies in the
3401 second line of code were not always recognized correctly.
3402
Georg Brandl14404b62008-01-19 19:27:05 +00003403- Issue #1679: "0x" was taken as a valid integer literal.
3404
Georg Brandl6caad7d2008-01-26 14:19:22 +00003405- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003406 added.
3407
Christian Heimesc94e2b52008-01-14 04:13:37 +00003408- sys.float_info / PyFloat_GetInfo: The floating point information
3409 object was converted from a dict to a specialized structseq object.
3410
Georg Brandl3ee81df2008-05-17 18:14:43 +00003411- Patch #1816: Added sys.flags structseq. It exposes the status of
3412 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003413
Georg Brandl3ee81df2008-05-17 18:14:43 +00003414- Objects/structseq.c: Implemented new structseq representation. The
3415 patch makes structseqs (e.g. the return value of os.stat) more
3416 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003417
Georg Brandl3ee81df2008-05-17 18:14:43 +00003418- Patch #1700288: added a type attribute cache that caches method
3419 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003420
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003421- Bug #1776: __import__() no longer accepts filenames on any platform.
3422 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003423
Georg Brandlaed6c662008-01-07 17:25:53 +00003424- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3425
Georg Brandl3ee81df2008-05-17 18:14:43 +00003426- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3427 envvar and sys.dont_write_bytecode attribute. All these can be set
3428 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003429
Georg Brandl3ee81df2008-05-17 18:14:43 +00003430- Improve some exception messages when Windows fails to load an
3431 extension module. Now we get for example '%1 is not a valid Win32
3432 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003433
Georg Brandl3ee81df2008-05-17 18:14:43 +00003434- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003436- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3437 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003438
Christian Heimes0a8143f2007-12-18 23:22:54 +00003439- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003440 and INF. float("nan"), float("inf") and float("-inf") now work on
3441 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003442
Georg Brandl3ee81df2008-05-17 18:14:43 +00003443- Compiler now generates simpler and faster code for dictionary
3444 literals. The oparg for BUILD_MAP now indicates an estimated
3445 dictionary size. There is a new opcode, STORE_MAP, for adding
3446 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003447
Georg Brandl3ee81df2008-05-17 18:14:43 +00003448- Issue #1638: %zd configure test fails on Linux.

3458
Nick Coghlanef01d822007-12-03 12:55:17 +00003459- PEP 366: Allow explicit relative imports when executing modules
3460 inside packages with the -m switch via a new module level
3461 __package__ attribute.
3462

3476 file can now be directly executed by passing their name to the
3477 interpreter. The directory/zipfile is automatically inserted as the
3478 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003479
Georg Brandl3ee81df2008-05-17 18:14:43 +00003480- Issue #1265: Fix a problem with sys.settrace, if the tracing
3481 function uses a generator expression when at the same time the
3482 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003483
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003484- sets and frozensets now have an isdisjoint() method.
3485
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003486- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00003488- Fix warnings found by the new version of the Coverity checker.
3489
Georg Brandl5a7eca12010-03-21 19:29:04 +00003490- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003491 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3492 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003493
Georg Brandl3ee81df2008-05-17 18:14:43 +00003494- Issue #1686386: Tuple's tp_repr did not take into account the
3495 possibility of having a self-referential tuple, which is possible
3496 from C code. Nor did object's tp_str consider that a type's tp_str
3497 could do something that could lead to an inifinite recursion.
3498 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3499 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003500
Georg Brandl3ee81df2008-05-17 18:14:43 +00003501- Issue #1164: It was possible to trigger deadlock when using the
3502 'print' statement to write to a file since the GIL was not released
3503 as needed. Now PyObject_Print() does the right thing along with
3504 various tp_print implementations of the built-in types and those in
3505 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003506
Georg Brandl3ee81df2008-05-17 18:14:43 +00003507- Issue #1147: Exceptions were directly allowing string exceptions in
3508 their throw() method even though string exceptions no longer

Brett Cannon1e534b52007-09-07 04:18:30 +00003514- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003515 PyObject_Call() never calling back out to Python code to trigger
3516 recursion depth updates/checks. Required the creation of a static
3517 RuntimeError instance in case normalizing an exception put the
3518 recursion check value past its limit. Fixes crashers
3519 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003534- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003535 __*__ attributes. (Some already existed, e.g., __doc__ and
3536 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003537
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003538- Add -3 option to the interpreter to warn about features that are

3542 calls.
3543
Collin Winter62903052007-05-18 23:11:24 +00003544- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003545 "except E as target:". This is to provide forwards compatibility
3546 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003553- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003554 setting a plain string, ie don't expand to single letter identifiers.
3555
Raymond Hettinger13936692007-04-11 18:40:58 +00003556- Request #1191699: Slices can now be pickled.
3557
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003558- Request #1193128: str.translate() now allows a None argument for

3560 remaining characters.
3561
Georg Brandl5cb76c12007-03-21 09:00:39 +00003562- Patch #1682205: a TypeError while unpacking an iterable is no longer

3566
Guido van Rossum143b5642007-03-23 04:58:42 +00003567- Bug #1683368: The object.__init__() and object.__new__() methods are
3568 now stricter in rejecting excess arguments. The only time when
3569 either allows excess arguments is when it is not overridden and the
3570 other one is. For backwards compatibility, when both are
3571 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003572 warning later). Also, type.__init__() insists on the same signature
3573 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003574
Georg Brandl3ee81df2008-05-17 18:14:43 +00003575- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3576 object to complex using its __complex__() method before falling back
3577 to the __float__() method. Therefore, the functions in the cmath
3578 module now can operate on objects that define a __complex__()
3579 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00003597- Bug #1678647: write a newline after printing an exception in any
3598 case, even when converting the value to a string failed.
3599
Georg Brandl871f1bc2007-03-12 13:17:36 +00003600- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003601 its argument, if it exists. If not, it will work like before. This
3602 allows customizing the output of dir() in the presence of a
3603 __getattr__().

3613 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003614
Georg Brandlaa2321b2007-03-07 00:40:28 +00003615- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003616 makes the filenames the warning module prints much more sensible
3617 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003630- Patch #1674228: when assigning a slice (old-style), check for the
3631 sq_ass_slice instead of the sq_slice slot.
3632
Georg Brandl3ee81df2008-05-17 18:14:43 +00003633- When printing an unraisable error, don't print exceptions. before

Andrew M. Kuchlinge45a77a2008-01-19 16:26:13 +00004240- Patch #742598: Add .timeout attribute to SocketServer that calls
4241 .handle_timeout() when no requests are received.
4242
Thomas Heller2456a3c2007-03-09 20:39:22 +00004243- Bug #1651235: When a tuple was passed to a ctypes function call,
4244 Python would crash instead of raising an error.
4245

4247 returned string up to the first NUL character.
4248

4258
Georg Brandl3ee81df2008-05-17 18:14:43 +00004259- unittest now verifies more of its assumptions. In particular,
4260 TestCase and TestSuite subclasses (not instances) are no longer
4261 accepted in TestSuite.addTest(). This should cause no
4262 incompatibility since it never made sense with ordinary subclasses
4263 -- the failure just occurred later, with a more cumbersome
4264 exception.

4548 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004549
Georg Brandl3ee81df2008-05-17 18:14:43 +00004550- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004551 that the SMTP.starttls() caller no longer needs to call ehlo()
4552 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004553 does not claim to support starttls. Adds the
4554 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4635 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4636 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004653 time so that opening a database previously created with the DB_DUP
4654 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4655 opens. Specifically: dictionary assignment to a DB object will
4656 replace all values for a given key when the database allows
4657 duplicate values. DB users should use DB.put(k, v) when they want
4658 to store duplicates; not DB[k] = v.

4665 characters with ASCII value less than 32. Also, it correctly quotes
4666 dots only if they occur on a single line, as opposed to the previous
4667 behavior of quoting dots if they are the second character of any
4668 line.

4991-----
4992
Georg Brandl3ee81df2008-05-17 18:14:43 +00004993- Unified naming convention for free lists and their limits. All free
4994 lists in Object/ are named ``free_list``, the counter ``numfree``
4995 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4996 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004997
Georg Brandl3ee81df2008-05-17 18:14:43 +00004998- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4999 to ``PyTuple_SetItem``, it can be used to populate a brand new
5000 frozenset; but it does not steal a reference to the added item.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005004- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5005 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5006 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005007
5008- Patch #1720595: add T_BOOL to the range of structmember types.
5009
5010- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5011 ``PyFloat_GetInfo()`` to the float API.
5012
Georg Brandl3ee81df2008-05-17 18:14:43 +00005013- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5014 of w# format code incorrectly truncated the length to an int, even
5015 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5016 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005017
Georg Brandl3ee81df2008-05-17 18:14:43 +00005018- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5019 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005021- PEP 3123: Provide forward compatibility with Python 3.0, while
5022 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5023 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005024
Georg Brandl3ee81df2008-05-17 18:14:43 +00005025- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5026 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005027
5028- Patch #1733960: Allow T_LONGLONG to accept ints.

5036- Fix some leftovers from the conversion from int to Py_ssize_t
5037 (relevant to strings and sequences of more than 2**31 items).
5038
5039- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5040 outside of pystate.c and should not be necessary.
5041
Georg Brandl3ee81df2008-05-17 18:14:43 +00005042- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5043 absolute imports. In earlier versions they might have used relative
5044 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005045
Georg Brandl3ee81df2008-05-17 18:14:43 +00005046- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5047 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005048
Georg Brandl3ee81df2008-05-17 18:14:43 +00005049- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005056- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5057 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5058 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5059 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005060
Georg Brandl3ee81df2008-05-17 18:14:43 +00005061- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005074- Removed the macfs module. It had been deprecated since Python 2.5.
5075 This lead to the deprecation of macostools.touched() as it relied
5076 solely on macfs and was a no-op under OS X.
