2026
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002027- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2028 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2029 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2030 ``printf`` function, whereas PyString_FromFormat has an independent
2031 implementation and uses "%zd" on all platforms for size_t values.
2032 This makes a difference on win64, where ``printf`` needs "%Id" to display

Antoine Pitrou0668c622008-08-26 22:42:08 +00002053 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2054 mechanism. In the process, fix a bug where isinstance() and issubclass(),

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002193What's New in Python 2.6 beta 3?
2194================================
2195
Barry Warsaw07a4a382008-08-21 01:15:08 +00002196*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002197
2198Core and Builtins
2199-----------------
2200
Guido van Rossumf8402962008-08-20 15:01:50 +00002201- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2202 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2203 extensions do not automatically benefit from the class attribute
2204 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2205 to their tp_flags field if they care. This is a backwards
2206 compatibility feature; in 3.0, all types will use the cache by
2207 default.
2208
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002209- Keyword arguments can now follow starred arguments. (``f(a, *args,
2210 keyword=23)`` is now valid syntax.)
2211
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002212- ctypes function pointers that are COM methods have a boolean True
2213 value again.
2214
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002215- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2216 by denying s# to parse objects that have a releasebuffer procedure,
2217 and introducing s*.
2218
Georg Brandl1e13ea92008-08-11 09:07:59 +00002219- Issue #3537: Fix an assertion failure when an empty but presized dict
2220 object was stored in the freelist.
2221
Mark Dickinsonb6467572008-08-04 21:30:09 +00002222- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2223 ValueError consistently across platforms.
2224
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002225- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2226 (64bit Unix, for example), unichr() would truncate its argument and return
2227 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2228
Neal Norwitze7d8be82008-07-31 17:17:14 +00002229- Apply security patches from Apple.
2230
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002231- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2232 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2233
Antoine Pitrou92f82162008-07-25 22:22:08 +00002234- Issue #1819: function calls with several named parameters are now on
2235 average 35% faster (as measured by pybench).
2236
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002237- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2238 the python debugger steps into a class statement: the free variables (local
2239 variables defined in an outer scope) would be deleted from the outer scope.
2240
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002241- Issue #2620: Overflow checking when allocating or reallocating memory
2242 was not always being done properly in some python types and extension
2243 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2244 all been updated to perform better checks and places in the code that
2245 would previously leak memory on the error path when such an allocation
2246 failed have been fixed.

2249-------
2250
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002251- Issue #3612: Added some missing basic types in ctypes.wintypes.
2252
Benjamin Petersone977ad42008-08-20 01:42:01 +00002253- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2254 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2255
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002256- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2257 version reported by these tools does not necessarily follow the python
2258 version numbering scheme, so the module is less strict when parsing it.
2259
Nick Coghlanf70385a2008-08-18 12:42:46 +00002260- Issue #2235: Added Py3k warnings for types which will become unhashable
2261 under the stricter __hash__ inheritance rules in 3.0. Several types
2262 which did not meet the rules for hash invariants and were already
2263 unhashable in 3.0 have now been explicitly flagged as unhashable in
2264 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2265 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2266
Brett Cannon88f801d2008-08-18 00:46:22 +00002267- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2268 imported into the module but exposed as part of the module's API.
2269
Brett Cannon7b96f072008-08-18 00:41:11 +00002270- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2271
Brett Cannon46225e72008-08-18 00:36:52 +00002272- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2273
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002274- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2275
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002276- Issue #3575: Incremental decoder's decode function now takes bytearray
2277 by using 's*' instead of 't#'.
2278
Jesus Cea585ad8a2009-07-02 15:37:21 +00002279- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002280 fails unicode conversion on 2nd parameter. (windows only)
2281
Georg Brandl21896072010-08-01 22:31:28 +00002282- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00002283 in a redirect.
2284
Brett Cannonabe423e2008-08-16 21:47:07 +00002285- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002286 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002287
Facundo Batistaeb90b782008-08-16 14:44:07 +00002288- Issue #2776: fixed small issue when handling an URL with double slash
2289 after a 302 response in the case of not going through a proxy.
2290
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002291- Issue #2676: in the email package, content-type parsing was hanging on
2292 pathological input because of quadratic or exponential behaviour of a
2293 regular expression.
2294
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002295- Issue #3476: binary buffered reading through the new "io" library is now
2296 thread-safe.
2297
Brett Cannonbf3157b2008-08-14 05:00:03 +00002298- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2299 since mimetools itself is deprecated. Because modules are cached, all
2300 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2301
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002302- Issue #3134: shutil referenced undefined WindowsError symbol.
2303
Robert Schuppenies14646332008-08-10 11:01:53 +00002304- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2305 menu entries were not deleted.
2306
Brett Cannon83e81842008-08-09 23:30:55 +00002307- Copied the implementation of reduce() to _functools.reduce() to have a
2308 version that did not raise a DeprecationWarning under -3.
2309
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002310- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2311 a MemoryError rather than silently stop the iteration.
2312
Guido van Rossum59ce9012008-08-09 14:55:34 +00002313- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2314 to _sre.compile() will now be rejected. This should not affect anybody
2315 since the re.compile() function never generates invalid re-bytecode.
2316
Skip Montanaroa032bf42008-08-08 22:52:51 +00002317- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2318 upon first access it can be automatically initialized from the csv file if
2319 it wasn't initialized during instantiation.
2320
Brett Cannon3aa2a492008-08-06 22:28:09 +00002321- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2322 the reload() built-in has been removed.
2323
Brett Cannon7e30b672008-08-04 21:52:25 +00002324- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002325 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2333 raised an AttributeError.
2334
Benjamin Peterson01a24322008-07-28 23:35:27 +00002335- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002336 asking for a specific length. This problem only affected files opened
2337 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002338
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002339- Issue #3449: Update decimal module to use most recent specification
2340 (v. 1.68) and tests (v. 2.58) from IBM.
2341
Georg Brandl21896072010-08-01 22:31:28 +00002342- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002343

2346
Georg Brandlf9efabb2008-07-23 15:16:45 +00002347- Deprecate the "ast" parser function aliases.
2348
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002349- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
2350
2351- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2352 invalid arguments.
2353
2354- Issue #3302: Fix several crashes when calling locale's gettext functions
2355 with None arguments.
2356
2357- Issue #3389: Allow resolving dotted names for handlers in logging
2358 configuration files.
2359

2361
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002362- Issue #3394: zipfile.writestr sets external attributes when passed a
2363 file name rather than a ZipInfo instance, so files are extracted with
2364 mode 0600 rather than 000 under Unix.
2365
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002366- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2367 argument in python 2.5, this broke code that subclassed Popen to include its
2368 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002378- Issue #2235: the C API function PyObject_HashNotImplemented and its
2379 interaction with the tp_hash slot (added in 2.6b2) are now documented
2380
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002381- Issue #643841: The language reference now provides more detailed
2382 coverage of the lookup process for special methods. The disclaimers
2383 regarding lack of coverage of new-style classes have also been
2384 removed, since the coverage is now fairly reasonable.

2389
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002390*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002392Core and Builtins
2393-----------------
2394
Georg Brandl3e483f62008-07-16 22:57:41 +00002395- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2396 its methods now allow for items objects that can be converted to
2397 an integer using operator.index().
2398
Mark Dickinson64b7e502008-07-16 09:40:03 +00002399- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2400 produced a ValueError instead of giving the correct float.
2401
Eric Smitha5fa5a22008-07-16 00:11:49 +00002402- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2403 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2404
Mark Dickinson7103aa42008-07-15 19:08:33 +00002405- Issue #3008: the float type has a new instance method 'float.hex'
2406 and a new class method 'float.fromhex' to convert floating-point
2407 numbers to and from hexadecimal strings, respectively.
2408
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002409- Issue #2235: __hash__ is once again inherited by default. To allow
2410 collections.Hashable to remain meaningful in the presence of the
2411 default hash implementation (object.__hash__), it is now possible
2412 to explicit block inheritance of hash by setting __hash__=None at
2413 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2414 level.
2415
Nick Coghlanb028f502008-07-13 14:52:36 +00002416- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2417 the parent module cannot be found while performing an absolute import.
2418 This means that an incorrectly defined __package__ attribute will
2419 now only prevent relative imports in that module rather than causing
2420 all imports from that module to fail.
2421
Nick Coghlan14ff9942008-07-08 14:21:42 +00002422- Issue #2517: Allow unicode messages in Exceptions again by correctly
2423 bypassing the instance dictionary when looking up __unicode__ on
2424 new-style classes.
2425
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002426- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2427 set to a custom object whose write() method happens to install
2428 another file in sys.stdout.
2429
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002430- Issue #3088: Corrected a race condition in classes derived from
2431 threading.local: the first member set by a thread could be saved in
2432 another thread's dictionary.
2433
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002434- Issue #3004: Minor change to slice.indices(): the start and stop
2435 arguments are now treated identically, making the behaviour easier
2436 to describe and understand. For example, slice(None, -10,
2437 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2438 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2439 10, -1).
2440
Georg Brandl278fc502008-07-19 12:46:12 +00002441- Issue #3219: Calling a function with repeated keyword arguments,
2442 f(a=2, a=23), would not cause a syntax error. This was a regression
2443 from 2.4 caused by the switch to the new compiler.

2446 other freelists. Changes their CompactFreeList apis into
2447 ClearFreeList apis and calls them via gc.collect().

2453 api functions without holding the GIL, which could lead to a fatal
2454 error when they failed.
2455

Georg Brandl5cc774e2008-06-11 20:28:06 +00002893 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002894
2895 This is controlled by the configure argument ``--with-universal-archs``:
2896
2897 - ``--with-universal-archs=all``: install 4-way universal
2898
2899 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2900
2901 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2902
2903 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002955- Issue #1631171: Re-implement the 'warnings' module in C (the
2956 original Python code has been kept as backup). This will allow for
2957 using the 'warning's machinery in such places as the parser where
2958 use of pure Python code is not possible. Both the ``showarning()``
2959 and ``formatwarning()`` gain an optional 'line' argument which is
2960 not called by default for backwards-compatibility reasons. Setting
2961 ``warnings.showwarning()`` to an implementation that lacks support
2962 for the ``line`` argument will raise a DeprecationWarning.

2986
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002987- The getpass module has been improved on Unix. It now uses /dev/tty
2988 by default and uses stderr instead of stdout. A GetPassWarning is
2989 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003025- Issue #2550: The approach used by client/server code for obtaining
3026 ports to listen on in network-oriented tests has been refined in an
3027 effort to facilitate running multiple instances of the entire
3028 regression test suite in parallel without issue.
3029 test_support.bind_port() has been fixed such that it will always
3030 return a unique port -- which wasn't always the case with the
3031 previous implementation, especially if socket options had been set
3032 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3033 new implementation of bind_port() will actually raise an exception
3034 if it is passed an AF_INET/SOCK_STREAM socket with either the
3035 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3036 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3037 the socket it's been passed. This currently only applies to
3038 Windows. This option prevents any other sockets from binding to the
3039 host/port we've bound to, thus removing the possibility of the
3040 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3041 when a second SOCK_STREAM socket binds and accepts to a host/port
3042 that's already been bound by another socket. The optional preferred
3043 port parameter to bind_port() has been removed. Under no
3044 circumstances should tests be hard coding ports!
3045
3046 test_support.find_unused_port() has also been introduced, which will
3047 pass a temporary socket object to bind_port() in order to obtain an
3048 unused port. The temporary socket object is then closed and
3049 deleted, and the port is returned. This method should only be used
3050 for obtaining an unused port in order to pass to an external program
3051 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3052 a parameter to a server-oriented class that doesn't give you direct
3053 access to the underlying socket used.
3054
3055 Finally, test_support.HOST has been introduced, which should be used
3056 for the host argument of any relevant socket calls (i.e. bind and
3057 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003058
3059 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003060 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003061 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3062 test_asynchat and test_socket_ssl.
3063
Georg Brandl3ee81df2008-05-17 18:14:43 +00003064 It is now possible for multiple instances of the regression test
3065 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003271 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
3272 files are used. On all linux systems the --with-system-ffi
3273 configure option defaults to "yes".

Fred Drakea8ee94b2008-03-01 02:45:07 +00003334- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003335 644. The mode is now inherited from the py file.

Facundo Batistafc2d0102008-02-23 12:01:13 +00003343
Eric Smitha73fbe72008-02-23 03:09:44 +00003344- Added the future_builtins module, which contains hex() and oct().
3345 These are the PEP 3127 version of these functions, designed to be
3346 compatible with the hex() and oct() builtins from Python 3.0. They
3347 differ slightly in their output formats from the existing, unchanged
3348 Python 2.6 builtins. The expected usage of the future_builtins
3349 module is:
3350 from future_builtins import hex, oct
3351
Eric Smith7ef40bf2008-02-20 23:34:22 +00003352- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3353 exponents for exponents with absolute value < 100. Follows C99
3354 standard. This is a change on Windows, which would use 3 digits.
3355 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3356 so that any alterations it does to the resulting string will be
3357 available in stringlib/formatter.h (for float.__format__).
3358
Eric Smith5a3c1352008-02-19 13:21:56 +00003359- Implemented PEP 3101, Advanced String Formatting. This adds a new
3360 builtin format(); a format() method for str and unicode; a
3361 __format__() method to object, str, unicode, int, long, float, and
3362 datetime; the class string.Formatter; and the C API
3363 PyObject_Format().
3364
Georg Brandl3ee81df2008-05-17 18:14:43 +00003365- Fixed several potential crashes, all caused by specially crafted
3366 __del__ methods exploiting objects in temporarily inconsistent
3367 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003368
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003369- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003370 prevent a possible crash: an Abstract Base Class would try to access
3371 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003372

Georg Brandl3ee81df2008-05-17 18:14:43 +00003376- Clear all free lists during a gc.collect() of the highest generation
3377 in order to allow pymalloc to free more arenas. Python may give back
3378 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003379
Georg Brandl3ee81df2008-05-17 18:14:43 +00003380- Issue #2045: Fix an infinite recursion triggered when printing a
3381 subclass of collections.defaultdict, if its default_factory is set
3382 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003383
Christian Heimesf75dbef2008-02-08 00:11:31 +00003384- Fixed a minor memory leak in dictobject.c. The content of the free
3385 list was not freed on interpreter shutdown.
3386
Georg Brandl5a7eca12010-03-21 19:29:04 +00003387- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003388 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003389
Georg Brandl3ee81df2008-05-17 18:14:43 +00003390- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3391 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003392 to compact the internal free lists of pre-allocted ints and floats.
3393
Georg Brandl3ee81df2008-05-17 18:14:43 +00003394- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3395 calls. Python expected the return type int but the fork familie
3396 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003397
Georg Brandl3ee81df2008-05-17 18:14:43 +00003398- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3399 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003410- Patch #1473257: generator objects gain a gi_code attribute. This is
3411 the same object as the func_code attribute of the function that
3412 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003413
Georg Brandl3ee81df2008-05-17 18:14:43 +00003414- Issue #1920: "while 0" statements were completely removed by the
3415 compiler, even in the presence of an "else" clause, which is
3416 supposed to be run when the condition is false. Now the compiler
3417 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003418
Guido van Rossumeead05f2008-01-24 18:21:02 +00003419- A few crashers fixed: weakref_in_del.py (issue #1377858);
3420 loosing_dict_ref.py (issue #1303614, test67.py);
3421 borrowed_ref_[34].py (not in tracker).
3422
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003423- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003424 suppressed while an extension is loaded by calling SetErrorMode in
3425 dynload_win.c. The error is still reported properly.
3426
Georg Brandl3ee81df2008-05-17 18:14:43 +00003427- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003428 several extension methods and modules do not work without unicode
3429 support.
3430
Georg Brandl26543b12008-01-21 18:36:51 +00003431- Issue #1882: when compiling code from a string, encoding cookies in the
3432 second line of code were not always recognized correctly.
3433
Georg Brandl14404b62008-01-19 19:27:05 +00003434- Issue #1679: "0x" was taken as a valid integer literal.
3435
Georg Brandl6caad7d2008-01-26 14:19:22 +00003436- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003437 added.
3438
Christian Heimesc94e2b52008-01-14 04:13:37 +00003439- sys.float_info / PyFloat_GetInfo: The floating point information
3440 object was converted from a dict to a specialized structseq object.
3441
Georg Brandl3ee81df2008-05-17 18:14:43 +00003442- Patch #1816: Added sys.flags structseq. It exposes the status of
3443 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003444
Georg Brandl3ee81df2008-05-17 18:14:43 +00003445- Objects/structseq.c: Implemented new structseq representation. The
3446 patch makes structseqs (e.g. the return value of os.stat) more
3447 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003448
Georg Brandl3ee81df2008-05-17 18:14:43 +00003449- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00003461- Improve some exception messages when Windows fails to load an
3462 extension module. Now we get for example '%1 is not a valid Win32
3463 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003471 and INF. float("nan"), float("inf") and float("-inf") now work on
3472 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003473
Georg Brandl3ee81df2008-05-17 18:14:43 +00003474- Compiler now generates simpler and faster code for dictionary
3475 literals. The oparg for BUILD_MAP now indicates an estimated
3476 dictionary size. There is a new opcode, STORE_MAP, for adding
3477 entries to the dictionary.

3520
Georg Brandl5a7eca12010-03-21 19:29:04 +00003521- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003522 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3523 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003524
Georg Brandl3ee81df2008-05-17 18:14:43 +00003525- Issue #1686386: Tuple's tp_repr did not take into account the
3526 possibility of having a self-referential tuple, which is possible
3527 from C code. Nor did object's tp_str consider that a type's tp_str
3528 could do something that could lead to an inifinite recursion.
3529 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3530 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003531
Georg Brandl3ee81df2008-05-17 18:14:43 +00003532- Issue #1164: It was possible to trigger deadlock when using the
3533 'print' statement to write to a file since the GIL was not released
3534 as needed. Now PyObject_Print() does the right thing along with
3535 various tp_print implementations of the built-in types and those in
3536 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003537
Georg Brandl3ee81df2008-05-17 18:14:43 +00003538- Issue #1147: Exceptions were directly allowing string exceptions in

3540 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00003545- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003546 PyObject_Call() never calling back out to Python code to trigger
3547 recursion depth updates/checks. Required the creation of a static
3548 RuntimeError instance in case normalizing an exception put the
3549 recursion check value past its limit. Fixes crashers

Georg Brandl3ee81df2008-05-17 18:14:43 +00003566 __*__ attributes. (Some already existed, e.g., __doc__ and
3567 __name__.)

3573 calls.
3574
Collin Winter62903052007-05-18 23:11:24 +00003575- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003576 "except E as target:". This is to provide forwards compatibility
3577 with Python 3.0.

3597
Guido van Rossum143b5642007-03-23 04:58:42 +00003598- Bug #1683368: The object.__init__() and object.__new__() methods are
3599 now stricter in rejecting excess arguments. The only time when
3600 either allows excess arguments is when it is not overridden and the
3601 other one is. For backwards compatibility, when both are
3602 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003603 warning later). Also, type.__init__() insists on the same signature
3604 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003605
Georg Brandl3ee81df2008-05-17 18:14:43 +00003606- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3607 object to complex using its __complex__() method before falling back
3608 to the __float__() method. Therefore, the functions in the cmath
3609 module now can operate on objects that define a __complex__()
3610 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00003628- Bug #1678647: write a newline after printing an exception in any
3629 case, even when converting the value to a string failed.
3630
Georg Brandl871f1bc2007-03-12 13:17:36 +00003631- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003632 its argument, if it exists. If not, it will work like before. This
3633 allows customizing the output of dir() in the presence of a
3634 __getattr__().

3644 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003645
Georg Brandlaa2321b2007-03-07 00:40:28 +00003646- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003647 makes the filenames the warning module prints much more sensible
3648 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003661- Patch #1674228: when assigning a slice (old-style), check for the
3662 sq_ass_slice instead of the sq_slice slot.
3663
Georg Brandl3ee81df2008-05-17 18:14:43 +00003664- When printing an unraisable error, don't print exceptions. before
3665 the name. This duplicates the behavior whening normally printing
3666 exceptions.

4295 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004576- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4577 with RFC 3207 and forgets any knowledge obtained from the server not
4578 obtained from the TLS negotiation itself. Patch contributed by Bill
4579 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004580
Georg Brandl3ee81df2008-05-17 18:14:43 +00004581- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004582 that the SMTP.starttls() caller no longer needs to call ehlo()
4583 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004584 does not claim to support starttls. Adds the
4585 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00004640- itertools.chain() now has an alternate constructor,

4666 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4667 silently miscode subclasses of those types. Now, it raises a
4668 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004669

Georg Brandl3ee81df2008-05-17 18:14:43 +00004684 time so that opening a database previously created with the DB_DUP
4685 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4686 opens. Specifically: dictionary assignment to a DB object will
4687 replace all values for a given key when the database allows
4688 duplicate values. DB users should use DB.put(k, v) when they want
4689 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004690

4696 characters with ASCII value less than 32. Also, it correctly quotes
4697 dots only if they occur on a single line, as opposed to the previous
4698 behavior of quoting dots if they are the second character of any
4699 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004700

5022-----
5023
Georg Brandl3ee81df2008-05-17 18:14:43 +00005024- Unified naming convention for free lists and their limits. All free
5025 lists in Object/ are named ``free_list``, the counter ``numfree``
5026 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5027 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005028
Georg Brandl3ee81df2008-05-17 18:14:43 +00005029- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5030 to ``PyTuple_SetItem``, it can be used to populate a brand new
5031 frozenset; but it does not steal a reference to the added item.

5043
Georg Brandl3ee81df2008-05-17 18:14:43 +00005044- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5045 of w# format code incorrectly truncated the length to an int, even
5046 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5047 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005048
Georg Brandl3ee81df2008-05-17 18:14:43 +00005049- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5067- Fix some leftovers from the conversion from int to Py_ssize_t
5068 (relevant to strings and sequences of more than 2**31 items).
5069
5070- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5071 outside of pystate.c and should not be necessary.
5072
Georg Brandl3ee81df2008-05-17 18:14:43 +00005073- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5074 absolute imports. In earlier versions they might have used relative
5075 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005076
Georg Brandl3ee81df2008-05-17 18:14:43 +00005077- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5078 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005079
Georg Brandl3ee81df2008-05-17 18:14:43 +00005080- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

5090 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005091

Georg Brandl3ee81df2008-05-17 18:14:43 +00005105- Removed the macfs module. It had been deprecated since Python 2.5.
5106 This lead to the deprecation of macostools.touched() as it relied
5107 solely on macfs and was a no-op under OS X.
