1831*Release date: 04-Dec-2008*
1832
1833Core and Builtins
1834-----------------
1835
1836- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1837 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1838 instead of throwing a MemoryError.
1839
1840- Issue #4367: Python would segfault during compiling when the unicodedata
1841 module couldn't be imported and \N escapes were present.
1842
1843- Issue #4348: Some bytearray methods returned that didn't cause any change to
1844 the bytearray, returned the same bytearray instead of a copy.
1845
1846- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1847
1848- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1849
1850- Issue #4048: The parser module now correctly validates relative imports.
1851
1852- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1853 exec statement.
1854
1855- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1856 method does not return iterators for the 4th and 5th items.

1859 __future__ import didn't work.
1860
1861- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1862 returned a path longer than MAX_PATH. (But It's doubtful this code path is

2019
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002020- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2021 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2022 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2023 ``printf`` function, whereas PyString_FromFormat has an independent
2024 implementation and uses "%zd" on all platforms for size_t values.
2025 This makes a difference on win64, where ``printf`` needs "%Id" to display
2026 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00002046 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2047 mechanism. In the process, fix a bug where isinstance() and issubclass(),

2049 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2050 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002186What's New in Python 2.6 beta 3?
2187================================
2188
Barry Warsaw07a4a382008-08-21 01:15:08 +00002189*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002190
2191Core and Builtins
2192-----------------
2193
Guido van Rossumf8402962008-08-20 15:01:50 +00002194- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2195 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2196 extensions do not automatically benefit from the class attribute
2197 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2198 to their tp_flags field if they care. This is a backwards
2199 compatibility feature; in 3.0, all types will use the cache by
2200 default.
2201
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002202- Keyword arguments can now follow starred arguments. (``f(a, *args,
2203 keyword=23)`` is now valid syntax.)
2204
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002205- ctypes function pointers that are COM methods have a boolean True
2206 value again.
2207
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002208- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2209 by denying s# to parse objects that have a releasebuffer procedure,
2210 and introducing s*.
2211
Georg Brandl1e13ea92008-08-11 09:07:59 +00002212- Issue #3537: Fix an assertion failure when an empty but presized dict
2213 object was stored in the freelist.
2214
Mark Dickinsonb6467572008-08-04 21:30:09 +00002215- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2216 ValueError consistently across platforms.
2217
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002218- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2219 (64bit Unix, for example), unichr() would truncate its argument and return
2220 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2221
Neal Norwitze7d8be82008-07-31 17:17:14 +00002222- Apply security patches from Apple.
2223
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002224- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2225 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2226
Antoine Pitrou92f82162008-07-25 22:22:08 +00002227- Issue #1819: function calls with several named parameters are now on
2228 average 35% faster (as measured by pybench).
2229
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002230- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2231 the python debugger steps into a class statement: the free variables (local
2232 variables defined in an outer scope) would be deleted from the outer scope.
2233
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002234- Issue #2620: Overflow checking when allocating or reallocating memory
2235 was not always being done properly in some python types and extension
2236 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2237 all been updated to perform better checks and places in the code that
2238 would previously leak memory on the error path when such an allocation
2239 failed have been fixed.

2242-------
2243
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002244- Issue #3612: Added some missing basic types in ctypes.wintypes.
2245
Benjamin Petersone977ad42008-08-20 01:42:01 +00002246- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2247 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2248
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002249- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2250 version reported by these tools does not necessarily follow the python
2251 version numbering scheme, so the module is less strict when parsing it.
2252
Nick Coghlanf70385a2008-08-18 12:42:46 +00002253- Issue #2235: Added Py3k warnings for types which will become unhashable
2254 under the stricter __hash__ inheritance rules in 3.0. Several types
2255 which did not meet the rules for hash invariants and were already
2256 unhashable in 3.0 have now been explicitly flagged as unhashable in
2257 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2258 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2259
Brett Cannon88f801d2008-08-18 00:46:22 +00002260- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2261 imported into the module but exposed as part of the module's API.
2262
Brett Cannon7b96f072008-08-18 00:41:11 +00002263- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2264
Brett Cannon46225e72008-08-18 00:36:52 +00002265- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2266
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002267- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2268
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002269- Issue #3575: Incremental decoder's decode function now takes bytearray
2270 by using 's*' instead of 't#'.
2271
Jesus Cea585ad8a2009-07-02 15:37:21 +00002272- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002273 fails unicode conversion on 2nd parameter. (windows only)
2274
Georg Brandl21896072010-08-01 22:31:28 +00002275- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00002276 in a redirect.
2277
Brett Cannonabe423e2008-08-16 21:47:07 +00002278- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002279 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002280
Facundo Batistaeb90b782008-08-16 14:44:07 +00002281- Issue #2776: fixed small issue when handling an URL with double slash
2282 after a 302 response in the case of not going through a proxy.
2283
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002284- Issue #2676: in the email package, content-type parsing was hanging on
2285 pathological input because of quadratic or exponential behaviour of a
2286 regular expression.
2287
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002288- Issue #3476: binary buffered reading through the new "io" library is now
2289 thread-safe.
2290
Brett Cannonbf3157b2008-08-14 05:00:03 +00002291- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2292 since mimetools itself is deprecated. Because modules are cached, all
2293 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2294
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002295- Issue #3134: shutil referenced undefined WindowsError symbol.
2296
Robert Schuppenies14646332008-08-10 11:01:53 +00002297- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2298 menu entries were not deleted.
2299
Brett Cannon83e81842008-08-09 23:30:55 +00002300- Copied the implementation of reduce() to _functools.reduce() to have a
2301 version that did not raise a DeprecationWarning under -3.
2302
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002303- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2304 a MemoryError rather than silently stop the iteration.
2305
Guido van Rossum59ce9012008-08-09 14:55:34 +00002306- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2307 to _sre.compile() will now be rejected. This should not affect anybody
2308 since the re.compile() function never generates invalid re-bytecode.
2309
Skip Montanaroa032bf42008-08-08 22:52:51 +00002310- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2311 upon first access it can be automatically initialized from the csv file if
2312 it wasn't initialized during instantiation.
2313
Brett Cannon3aa2a492008-08-06 22:28:09 +00002314- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2315 the reload() built-in has been removed.
2316
Brett Cannon7e30b672008-08-04 21:52:25 +00002317- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002318 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2320 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
2321 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
2322 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2323 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002324
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002325- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2326 raised an AttributeError.
2327
Benjamin Peterson01a24322008-07-28 23:35:27 +00002328- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002329 asking for a specific length. This problem only affected files opened
2330 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002331
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002332- Issue #3449: Update decimal module to use most recent specification
2333 (v. 1.68) and tests (v. 2.58) from IBM.
2334
Georg Brandl21896072010-08-01 22:31:28 +00002335- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002336

2339
Georg Brandlf9efabb2008-07-23 15:16:45 +00002340- Deprecate the "ast" parser function aliases.
2341
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002342- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
2343
2344- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2345 invalid arguments.
2346
2347- Issue #3302: Fix several crashes when calling locale's gettext functions
2348 with None arguments.
2349
2350- Issue #3389: Allow resolving dotted names for handlers in logging
2351 configuration files.
2352
2353- Deprecate the sunaudio module for removal in Python 3.0.
2354
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002355- Issue #3394: zipfile.writestr sets external attributes when passed a
2356 file name rather than a ZipInfo instance, so files are extracted with
2357 mode 0600 rather than 000 under Unix.
2358
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002359- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2360 argument in python 2.5, this broke code that subclassed Popen to include its
2361 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002371- Issue #2235: the C API function PyObject_HashNotImplemented and its
2372 interaction with the tp_hash slot (added in 2.6b2) are now documented
2373
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002374- Issue #643841: The language reference now provides more detailed
2375 coverage of the lookup process for special methods. The disclaimers
2376 regarding lack of coverage of new-style classes have also been
2377 removed, since the coverage is now fairly reasonable.

2381================================
2382
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002383*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002385Core and Builtins
2386-----------------
2387
Georg Brandl3e483f62008-07-16 22:57:41 +00002388- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2389 its methods now allow for items objects that can be converted to
2390 an integer using operator.index().
2391
Mark Dickinson64b7e502008-07-16 09:40:03 +00002392- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2393 produced a ValueError instead of giving the correct float.
2394
Eric Smitha5fa5a22008-07-16 00:11:49 +00002395- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2396 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2397
Mark Dickinson7103aa42008-07-15 19:08:33 +00002398- Issue #3008: the float type has a new instance method 'float.hex'
2399 and a new class method 'float.fromhex' to convert floating-point
2400 numbers to and from hexadecimal strings, respectively.
2401
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002402- Issue #2235: __hash__ is once again inherited by default. To allow
2403 collections.Hashable to remain meaningful in the presence of the
2404 default hash implementation (object.__hash__), it is now possible
2405 to explicit block inheritance of hash by setting __hash__=None at
2406 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2407 level.
2408
Nick Coghlanb028f502008-07-13 14:52:36 +00002409- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2410 the parent module cannot be found while performing an absolute import.
2411 This means that an incorrectly defined __package__ attribute will
2412 now only prevent relative imports in that module rather than causing
2413 all imports from that module to fail.
2414
Nick Coghlan14ff9942008-07-08 14:21:42 +00002415- Issue #2517: Allow unicode messages in Exceptions again by correctly
2416 bypassing the instance dictionary when looking up __unicode__ on
2417 new-style classes.
2418
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002419- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2420 set to a custom object whose write() method happens to install
2421 another file in sys.stdout.
2422
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002423- Issue #3088: Corrected a race condition in classes derived from
2424 threading.local: the first member set by a thread could be saved in
2425 another thread's dictionary.
2426
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002427- Issue #3004: Minor change to slice.indices(): the start and stop
2428 arguments are now treated identically, making the behaviour easier
2429 to describe and understand. For example, slice(None, -10,
2430 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2431 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2432 10, -1).
2433
Georg Brandl278fc502008-07-19 12:46:12 +00002434- Issue #3219: Calling a function with repeated keyword arguments,
2435 f(a=2, a=23), would not cause a syntax error. This was a regression
2436 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00002438- Issue #2862: Make int and float freelist management consistent with
2439 other freelists. Changes their CompactFreeList apis into
2440 ClearFreeList apis and calls them via gc.collect().

2446 api functions without holding the GIL, which could lead to a fatal
2447 error when they failed.
2448
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002449- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Georg Brandl5cc774e2008-06-11 20:28:06 +00002886 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002887
2888 This is controlled by the configure argument ``--with-universal-archs``:
2889
2890 - ``--with-universal-archs=all``: install 4-way universal
2891
2892 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2893
2894 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2895
2896 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002948- Issue #1631171: Re-implement the 'warnings' module in C (the
2949 original Python code has been kept as backup). This will allow for
2950 using the 'warning's machinery in such places as the parser where
2951 use of pure Python code is not possible. Both the ``showarning()``
2952 and ``formatwarning()`` gain an optional 'line' argument which is
2953 not called by default for backwards-compatibility reasons. Setting
2954 ``warnings.showwarning()`` to an implementation that lacks support
2955 for the ``line`` argument will raise a DeprecationWarning.

2979
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002980- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00003010- Issue #2385: distutils.core.run_script() makes __file__ available,
3011 so the controlled environment will more closely mirror the typical
3012 script environment. This supports setup.py scripts that refer to
3013 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003018- Issue #2550: The approach used by client/server code for obtaining
3019 ports to listen on in network-oriented tests has been refined in an
3020 effort to facilitate running multiple instances of the entire
3021 regression test suite in parallel without issue.
3022 test_support.bind_port() has been fixed such that it will always
3023 return a unique port -- which wasn't always the case with the
3024 previous implementation, especially if socket options had been set
3025 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3026 new implementation of bind_port() will actually raise an exception
3027 if it is passed an AF_INET/SOCK_STREAM socket with either the
3028 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3029 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3030 the socket it's been passed. This currently only applies to
3031 Windows. This option prevents any other sockets from binding to the
3032 host/port we've bound to, thus removing the possibility of the
3033 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3034 when a second SOCK_STREAM socket binds and accepts to a host/port
3035 that's already been bound by another socket. The optional preferred
3036 port parameter to bind_port() has been removed. Under no
3037 circumstances should tests be hard coding ports!
3038
3039 test_support.find_unused_port() has also been introduced, which will
3040 pass a temporary socket object to bind_port() in order to obtain an
3041 unused port. The temporary socket object is then closed and
3042 deleted, and the port is returned. This method should only be used
3043 for obtaining an unused port in order to pass to an external program
3044 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3045 a parameter to a server-oriented class that doesn't give you direct
3046 access to the underlying socket used.
3047
3048 Finally, test_support.HOST has been introduced, which should be used
3049 for the host argument of any relevant socket calls (i.e. bind and
3050 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003051
3052 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003053 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003054 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3055 test_asynchat and test_socket_ssl.
3056
Georg Brandl3ee81df2008-05-17 18:14:43 +00003057 It is now possible for multiple instances of the regression test
3058 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00003327- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003328 644. The mode is now inherited from the py file.

Eric Smitha73fbe72008-02-23 03:09:44 +00003337- Added the future_builtins module, which contains hex() and oct().
3338 These are the PEP 3127 version of these functions, designed to be
3339 compatible with the hex() and oct() builtins from Python 3.0. They
3340 differ slightly in their output formats from the existing, unchanged
3341 Python 2.6 builtins. The expected usage of the future_builtins
3342 module is:
3343 from future_builtins import hex, oct
3344
Eric Smith7ef40bf2008-02-20 23:34:22 +00003345- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3346 exponents for exponents with absolute value < 100. Follows C99
3347 standard. This is a change on Windows, which would use 3 digits.
3348 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3349 so that any alterations it does to the resulting string will be
3350 available in stringlib/formatter.h (for float.__format__).
3351
Eric Smith5a3c1352008-02-19 13:21:56 +00003352- Implemented PEP 3101, Advanced String Formatting. This adds a new
3353 builtin format(); a format() method for str and unicode; a
3354 __format__() method to object, str, unicode, int, long, float, and
3355 datetime; the class string.Formatter; and the C API
3356 PyObject_Format().
3357
Georg Brandl3ee81df2008-05-17 18:14:43 +00003358- Fixed several potential crashes, all caused by specially crafted
3359 __del__ methods exploiting objects in temporarily inconsistent
3360 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003361
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003362- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003363 prevent a possible crash: an Abstract Base Class would try to access
3364 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003365

Georg Brandl3ee81df2008-05-17 18:14:43 +00003369- Clear all free lists during a gc.collect() of the highest generation
3370 in order to allow pymalloc to free more arenas. Python may give back
3371 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003372
Georg Brandl3ee81df2008-05-17 18:14:43 +00003373- Issue #2045: Fix an infinite recursion triggered when printing a
3374 subclass of collections.defaultdict, if its default_factory is set
3375 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003376
Christian Heimesf75dbef2008-02-08 00:11:31 +00003377- Fixed a minor memory leak in dictobject.c. The content of the free
3378 list was not freed on interpreter shutdown.
3379
Georg Brandl5a7eca12010-03-21 19:29:04 +00003380- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003381 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003382
Georg Brandl3ee81df2008-05-17 18:14:43 +00003383- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3384 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003385 to compact the internal free lists of pre-allocted ints and floats.
3386
Georg Brandl3ee81df2008-05-17 18:14:43 +00003387- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3388 calls. Python expected the return type int but the fork familie
3389 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003390
Georg Brandl3ee81df2008-05-17 18:14:43 +00003391- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00003403- Patch #1473257: generator objects gain a gi_code attribute. This is
3404 the same object as the func_code attribute of the function that
3405 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003406
Georg Brandl3ee81df2008-05-17 18:14:43 +00003407- Issue #1920: "while 0" statements were completely removed by the
3408 compiler, even in the presence of an "else" clause, which is
3409 supposed to be run when the condition is false. Now the compiler
3410 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003411
Guido van Rossumeead05f2008-01-24 18:21:02 +00003412- A few crashers fixed: weakref_in_del.py (issue #1377858);
3413 loosing_dict_ref.py (issue #1303614, test67.py);
3414 borrowed_ref_[34].py (not in tracker).
3415
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003416- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003417 suppressed while an extension is loaded by calling SetErrorMode in
3418 dynload_win.c. The error is still reported properly.
3419
Georg Brandl3ee81df2008-05-17 18:14:43 +00003420- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003421 several extension methods and modules do not work without unicode
3422 support.
3423
Georg Brandl26543b12008-01-21 18:36:51 +00003424- Issue #1882: when compiling code from a string, encoding cookies in the
3425 second line of code were not always recognized correctly.
3426
Georg Brandl14404b62008-01-19 19:27:05 +00003427- Issue #1679: "0x" was taken as a valid integer literal.
3428
Georg Brandl6caad7d2008-01-26 14:19:22 +00003429- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003430 added.
3431
Christian Heimesc94e2b52008-01-14 04:13:37 +00003432- sys.float_info / PyFloat_GetInfo: The floating point information
3433 object was converted from a dict to a specialized structseq object.
3434
Georg Brandl3ee81df2008-05-17 18:14:43 +00003435- Patch #1816: Added sys.flags structseq. It exposes the status of
3436 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003437
Georg Brandl3ee81df2008-05-17 18:14:43 +00003438- Objects/structseq.c: Implemented new structseq representation. The
3439 patch makes structseqs (e.g. the return value of os.stat) more
3440 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003441
Georg Brandl3ee81df2008-05-17 18:14:43 +00003442- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00003464 and INF. float("nan"), float("inf") and float("-inf") now work on
3465 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003466
Georg Brandl3ee81df2008-05-17 18:14:43 +00003467- Compiler now generates simpler and faster code for dictionary
3468 literals. The oparg for BUILD_MAP now indicates an estimated
3469 dictionary size. There is a new opcode, STORE_MAP, for adding
3470 entries to the dictionary.

Neal Norwitz44f326e2007-10-05 05:29:17 +00003512- Fix warnings found by the new version of the Coverity checker.
3513
Georg Brandl5a7eca12010-03-21 19:29:04 +00003514- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003515 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3516 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003517
Georg Brandl3ee81df2008-05-17 18:14:43 +00003518- Issue #1686386: Tuple's tp_repr did not take into account the
3519 possibility of having a self-referential tuple, which is possible
3520 from C code. Nor did object's tp_str consider that a type's tp_str
3521 could do something that could lead to an inifinite recursion.
3522 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3523 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003524
Georg Brandl3ee81df2008-05-17 18:14:43 +00003525- Issue #1164: It was possible to trigger deadlock when using the
3526 'print' statement to write to a file since the GIL was not released
3527 as needed. Now PyObject_Print() does the right thing along with
3528 various tp_print implementations of the built-in types and those in
3529 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003530
Georg Brandl3ee81df2008-05-17 18:14:43 +00003531- Issue #1147: Exceptions were directly allowing string exceptions in
3532 their throw() method even though string exceptions no longer
3533 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003534
Georg Brandl3ee81df2008-05-17 18:14:43 +00003535- Issue #1096: Prevent a segfault from getting the repr of a very
3536 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003537
Brett Cannon1e534b52007-09-07 04:18:30 +00003538- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003539 PyObject_Call() never calling back out to Python code to trigger
3540 recursion depth updates/checks. Required the creation of a static
3541 RuntimeError instance in case normalizing an exception put the
3542 recursion check value past its limit. Fixes crashers
3543 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003544

Neal Norwitz0ac60192007-05-27 04:08:54 +00003558- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003559 __*__ attributes. (Some already existed, e.g., __doc__ and
3560 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003561
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003562- Add -3 option to the interpreter to warn about features that are
3563 deprecated and will be changed/removed in Python 3.0.
3564
Georg Brandl2134e752007-05-21 20:34:16 +00003565- Patch #1686487: you can now pass any mapping after '**' in function
3566 calls.
3567
Collin Winter62903052007-05-18 23:11:24 +00003568- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003569 "except E as target:". This is to provide forwards compatibility
3570 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003571
Brett Cannon229cee22007-05-05 01:34:02 +00003572- Deprecate BaseException.message as per PEP 352.
3573
Georg Brandl3ee81df2008-05-17 18:14:43 +00003574- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003575 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003577- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003578 setting a plain string, ie don't expand to single letter identifiers.
3579
Raymond Hettinger13936692007-04-11 18:40:58 +00003580- Request #1191699: Slices can now be pickled.
3581
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003582- Request #1193128: str.translate() now allows a None argument for
3583 translations that only remove characters without re-mapping the
3584 remaining characters.
3585
Georg Brandl5cb76c12007-03-21 09:00:39 +00003586- Patch #1682205: a TypeError while unpacking an iterable is no longer

3590
Guido van Rossum143b5642007-03-23 04:58:42 +00003591- Bug #1683368: The object.__init__() and object.__new__() methods are
3592 now stricter in rejecting excess arguments. The only time when
3593 either allows excess arguments is when it is not overridden and the
3594 other one is. For backwards compatibility, when both are
3595 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003596 warning later). Also, type.__init__() insists on the same signature
3597 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003598
Georg Brandl3ee81df2008-05-17 18:14:43 +00003599- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3600 object to complex using its __complex__() method before falling back
3601 to the __float__() method. Therefore, the functions in the cmath
3602 module now can operate on objects that define a __complex__()
3603 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003604
Georg Brandl3ee81df2008-05-17 18:14:43 +00003605- Patch #1623563: allow __class__ assignment for classes with
3606 __slots__. The old and the new class are still required to have the
3607 same slot names.

3613 ``object.__reduce_ex__()`` is called with an object that is faking
3614 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003615
Georg Brandl3ee81df2008-05-17 18:14:43 +00003616- Patch #1680015: Don't modify __slots__ tuple if it contains an

3620
Georg Brandl7b9c5552007-03-12 14:30:05 +00003621- Bug #1678647: write a newline after printing an exception in any
3622 case, even when converting the value to a string failed.
3623
Georg Brandl871f1bc2007-03-12 13:17:36 +00003624- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003625 its argument, if it exists. If not, it will work like before. This
3626 allows customizing the output of dir() in the presence of a
3627 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003635- Patch #1491866: change the complex() constructor to allow
3636 parthensized forms. This means complex(repr(x)) now works instead of
3637 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003638
Georg Brandlaa2321b2007-03-07 00:40:28 +00003639- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003640 makes the filenames the warning module prints much more sensible
3641 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003642
Georg Brandl49aafc92007-03-07 00:34:46 +00003643- Variant of patch #697613: don't exit the interpreter on a SystemExit
3644 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003645 variable is given, but break into the interactive interpreter just
3646 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003654- Patch #1674228: when assigning a slice (old-style), check for the
3655 sq_ass_slice instead of the sq_slice slot.
3656
Georg Brandl3ee81df2008-05-17 18:14:43 +00003657- When printing an unraisable error, don't print exceptions. before
3658 the name. This duplicates the behavior whening normally printing
3659 exceptions.

4288 exception.

4501 partial fix for Bug #1574584.
4502
Georg Brandl3ee81df2008-05-17 18:14:43 +00004503- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004569- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4570 with RFC 3207 and forgets any knowledge obtained from the server not
4571 obtained from the TLS negotiation itself. Patch contributed by Bill
4572 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004573
Georg Brandl3ee81df2008-05-17 18:14:43 +00004574- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004575 that the SMTP.starttls() caller no longer needs to call ehlo()
4576 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004577 does not claim to support starttls. Adds the
4578 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4579 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004633- itertools.chain() now has an alternate constructor,

4659 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4660 silently miscode subclasses of those types. Now, it raises a
4661 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004662

Georg Brandl3ee81df2008-05-17 18:14:43 +00004677 time so that opening a database previously created with the DB_DUP
4678 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4679 opens. Specifically: dictionary assignment to a DB object will
4680 replace all values for a given key when the database allows
4681 duplicate values. DB users should use DB.put(k, v) when they want
4682 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004683

4689 characters with ASCII value less than 32. Also, it correctly quotes
4690 dots only if they occur on a single line, as opposed to the previous
4691 behavior of quoting dots if they are the second character of any
4692 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004693

5015-----
5016
Georg Brandl3ee81df2008-05-17 18:14:43 +00005017- Unified naming convention for free lists and their limits. All free
5018 lists in Object/ are named ``free_list``, the counter ``numfree``
5019 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5020 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005021
Georg Brandl3ee81df2008-05-17 18:14:43 +00005022- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5023 to ``PyTuple_SetItem``, it can be used to populate a brand new
5024 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005025
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005026- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

5029 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5030 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005031
5032- Patch #1720595: add T_BOOL to the range of structmember types.
5033
5034- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5035 ``PyFloat_GetInfo()`` to the float API.
5036
Georg Brandl3ee81df2008-05-17 18:14:43 +00005037- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5038 of w# format code incorrectly truncated the length to an int, even
5039 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5040 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005041
Georg Brandl3ee81df2008-05-17 18:14:43 +00005042- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5043 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005044
Georg Brandl3ee81df2008-05-17 18:14:43 +00005045- PEP 3123: Provide forward compatibility with Python 3.0, while
5046 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5047 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005048
Georg Brandl3ee81df2008-05-17 18:14:43 +00005049- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5050 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005051
5052- Patch #1733960: Allow T_LONGLONG to accept ints.

5059
5060- Fix some leftovers from the conversion from int to Py_ssize_t
5061 (relevant to strings and sequences of more than 2**31 items).
5062
5063- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5064 outside of pystate.c and should not be necessary.
5065
Georg Brandl3ee81df2008-05-17 18:14:43 +00005066- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5067 absolute imports. In earlier versions they might have used relative
5068 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005069
Georg Brandl3ee81df2008-05-17 18:14:43 +00005070- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5071 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005072
Georg Brandl3ee81df2008-05-17 18:14:43 +00005073- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5074 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005080- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5081 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5082 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5083 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005084

Georg Brandl3ee81df2008-05-17 18:14:43 +00005098- Removed the macfs module. It had been deprecated since Python 2.5.
5099 This lead to the deprecation of macostools.touched() as it relied
5100 solely on macfs and was a no-op under OS X.
