768What's New in Python 2.6.1
769==========================
770
771*Release date: 04-Dec-2008*
772
773Core and Builtins
774-----------------
775
776- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
777 interpreter to abort ("Fatal Python error: Could not reset the stack!")
778 instead of throwing a MemoryError.
779
780- Issue #4367: Python would segfault during compiling when the unicodedata
781 module couldn't be imported and \N escapes were present.
782
783- Issue #4348: Some bytearray methods returned that didn't cause any change to
784 the bytearray, returned the same bytearray instead of a copy.
785
786- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
787
788- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
789
790- Issue #4048: The parser module now correctly validates relative imports.
791
792- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

797
798- Issue #4209: Enabling unicode_literals and the print_function in the same
799 __future__ import didn't work.
800
801- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
802 returned a path longer than MAX_PATH. (But It's doubtful this code path is
803 really executed because I cannot move to such directory on win2k)
804
805- Issue #4069: When set.remove(element) is used with a set element, the element
806 is temporarily replaced with an equivalent frozenset. But the eventual
807 KeyError would always report the empty frozenset([]) as the missing key. Now
808 it correctly refers to the initial element.
809
810- Fixed C99 style comments in several files. Python is now C89 compatible
811 again.

959
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000960- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
961 PyString_FromFormat or PyErr_Format to display size_t values. The macro
962 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
963 ``printf`` function, whereas PyString_FromFormat has an independent
964 implementation and uses "%zd" on all platforms for size_t values.
965 This makes a difference on win64, where ``printf`` needs "%Id" to display
966 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +0000986 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
987 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1061 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1062 for catch_warnings() also led to an improvement in the raising of a

1086 from the same python interpreter, some environment variables would grow
1087 without limit.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001126What's New in Python 2.6 beta 3?
1127================================
1128
Barry Warsaw07a4a382008-08-21 01:15:08 +00001129*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001130
1131Core and Builtins
1132-----------------
1133
Guido van Rossumf8402962008-08-20 15:01:50 +00001134- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1135 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1136 extensions do not automatically benefit from the class attribute
1137 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1138 to their tp_flags field if they care. This is a backwards
1139 compatibility feature; in 3.0, all types will use the cache by
1140 default.
1141
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001142- Keyword arguments can now follow starred arguments. (``f(a, *args,
1143 keyword=23)`` is now valid syntax.)
1144
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001145- ctypes function pointers that are COM methods have a boolean True
1146 value again.
1147
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001148- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1149 by denying s# to parse objects that have a releasebuffer procedure,
1150 and introducing s*.
1151
Georg Brandl1e13ea92008-08-11 09:07:59 +00001152- Issue #3537: Fix an assertion failure when an empty but presized dict
1153 object was stored in the freelist.
1154
Mark Dickinsonb6467572008-08-04 21:30:09 +00001155- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1156 ValueError consistently across platforms.
1157
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001158- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1159 (64bit Unix, for example), unichr() would truncate its argument and return
1160 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1161
Neal Norwitze7d8be82008-07-31 17:17:14 +00001162- Apply security patches from Apple.
1163
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001164- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1165 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1166
Antoine Pitrou92f82162008-07-25 22:22:08 +00001167- Issue #1819: function calls with several named parameters are now on
1168 average 35% faster (as measured by pybench).
1169
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001170- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1171 the python debugger steps into a class statement: the free variables (local
1172 variables defined in an outer scope) would be deleted from the outer scope.
1173
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001174- Issue #2620: Overflow checking when allocating or reallocating memory
1175 was not always being done properly in some python types and extension
1176 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1177 all been updated to perform better checks and places in the code that
1178 would previously leak memory on the error path when such an allocation
1179 failed have been fixed.

1183
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001184- Issue #3612: Added some missing basic types in ctypes.wintypes.
1185
Benjamin Petersone977ad42008-08-20 01:42:01 +00001186- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1187 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1188
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001189- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1190 version reported by these tools does not necessarily follow the python
1191 version numbering scheme, so the module is less strict when parsing it.
1192
Nick Coghlanf70385a2008-08-18 12:42:46 +00001193- Issue #2235: Added Py3k warnings for types which will become unhashable
1194 under the stricter __hash__ inheritance rules in 3.0. Several types
1195 which did not meet the rules for hash invariants and were already
1196 unhashable in 3.0 have now been explicitly flagged as unhashable in
1197 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1198 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1199
Brett Cannon88f801d2008-08-18 00:46:22 +00001200- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1201 imported into the module but exposed as part of the module's API.
1202
Brett Cannon7b96f072008-08-18 00:41:11 +00001203- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1204
Brett Cannon46225e72008-08-18 00:36:52 +00001205- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001207- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1208
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001209- Issue #3575: Incremental decoder's decode function now takes bytearray
1210 by using 's*' instead of 't#'.
1211
Jesus Cea585ad8a2009-07-02 15:37:21 +00001212- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001213 fails unicode conversion on 2nd parameter. (windows only)
1214
Facundo Batista94f243a2008-08-17 03:38:39 +00001215- Issue 2464. urllib2 now supports a malformation in the URL received
1216 in a redirect.
1217
Brett Cannonabe423e2008-08-16 21:47:07 +00001218- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001219 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001220
Facundo Batistaeb90b782008-08-16 14:44:07 +00001221- Issue #2776: fixed small issue when handling an URL with double slash
1222 after a 302 response in the case of not going through a proxy.
1223
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001224- Issue #2676: in the email package, content-type parsing was hanging on
1225 pathological input because of quadratic or exponential behaviour of a
1226 regular expression.
1227
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001228- Issue #3476: binary buffered reading through the new "io" library is now
1229 thread-safe.
1230
Brett Cannonbf3157b2008-08-14 05:00:03 +00001231- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1232 since mimetools itself is deprecated. Because modules are cached, all
1233 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1234
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001235- Issue #3134: shutil referenced undefined WindowsError symbol.
1236
Robert Schuppenies14646332008-08-10 11:01:53 +00001237- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1238 menu entries were not deleted.
1239
Brett Cannon83e81842008-08-09 23:30:55 +00001240- Copied the implementation of reduce() to _functools.reduce() to have a
1241 version that did not raise a DeprecationWarning under -3.
1242
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001243- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1244 a MemoryError rather than silently stop the iteration.
1245
Guido van Rossum59ce9012008-08-09 14:55:34 +00001246- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1247 to _sre.compile() will now be rejected. This should not affect anybody
1248 since the re.compile() function never generates invalid re-bytecode.
1249
Skip Montanaroa032bf42008-08-08 22:52:51 +00001250- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1251 upon first access it can be automatically initialized from the csv file if
1252 it wasn't initialized during instantiation.
1253
Brett Cannon3aa2a492008-08-06 22:28:09 +00001254- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1255 the reload() built-in has been removed.
1256
Brett Cannon7e30b672008-08-04 21:52:25 +00001257- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001258 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001269 asking for a specific length. This problem only affected files opened
1270 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001271

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001295- Issue #3394: zipfile.writestr sets external attributes when passed a
1296 file name rather than a ZipInfo instance, so files are extracted with
1297 mode 0600 rather than 000 under Unix.
1298
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001299- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1300 argument in python 2.5, this broke code that subclassed Popen to include its

1312 interaction with the tp_hash slot (added in 2.6b2) are now documented
1313
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001314- Issue #643841: The language reference now provides more detailed
1315 coverage of the lookup process for special methods. The disclaimers
1316 regarding lack of coverage of new-style classes have also been

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001320What's New in Python 2.6 beta 2?
1321================================
1322
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001323*Release date: 17-Jul-2008*
1324
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001325Core and Builtins
1326-----------------
1327
Georg Brandl3e483f62008-07-16 22:57:41 +00001328- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1329 its methods now allow for items objects that can be converted to
1330 an integer using operator.index().
1331
Mark Dickinson64b7e502008-07-16 09:40:03 +00001332- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1333 produced a ValueError instead of giving the correct float.
1334
Eric Smitha5fa5a22008-07-16 00:11:49 +00001335- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1336 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1337
Mark Dickinson7103aa42008-07-15 19:08:33 +00001338- Issue #3008: the float type has a new instance method 'float.hex'
1339 and a new class method 'float.fromhex' to convert floating-point
1340 numbers to and from hexadecimal strings, respectively.
1341
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001342- Issue #2235: __hash__ is once again inherited by default. To allow
1343 collections.Hashable to remain meaningful in the presence of the
1344 default hash implementation (object.__hash__), it is now possible
1345 to explicit block inheritance of hash by setting __hash__=None at
1346 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1347 level.
1348
Nick Coghlanb028f502008-07-13 14:52:36 +00001349- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1350 the parent module cannot be found while performing an absolute import.
1351 This means that an incorrectly defined __package__ attribute will
1352 now only prevent relative imports in that module rather than causing
1353 all imports from that module to fail.
1354
Nick Coghlan14ff9942008-07-08 14:21:42 +00001355- Issue #2517: Allow unicode messages in Exceptions again by correctly
1356 bypassing the instance dictionary when looking up __unicode__ on
1357 new-style classes.
1358
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001359- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1360 set to a custom object whose write() method happens to install
1361 another file in sys.stdout.
1362
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001363- Issue #3088: Corrected a race condition in classes derived from
1364 threading.local: the first member set by a thread could be saved in
1365 another thread's dictionary.
1366
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001367- Issue #3004: Minor change to slice.indices(): the start and stop
1368 arguments are now treated identically, making the behaviour easier
1369 to describe and understand. For example, slice(None, -10,
1370 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1371 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1372 10, -1).
1373
Georg Brandl278fc502008-07-19 12:46:12 +00001374- Issue #3219: Calling a function with repeated keyword arguments,
1375 f(a=2, a=23), would not cause a syntax error. This was a regression
1376 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001377
Georg Brandl278fc502008-07-19 12:46:12 +00001378- Issue #2862: Make int and float freelist management consistent with
1379 other freelists. Changes their CompactFreeList apis into
1380 ClearFreeList apis and calls them via gc.collect().

1384
Thomas Heller57adf222008-08-14 19:10:48 +00001385- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1386 api functions without holding the GIL, which could lead to a fatal
1387 error when they failed.
1388
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001389- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1398 ForkingPickler.register() to resolve conflict with ctypes.
1399
Vinay Sajip51e65192008-07-18 09:01:10 +00001400- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001401
Thomas Heller880f5292008-07-15 19:39:38 +00001402- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1403 a valid dlerror() message.
1404
Thomas Heller2bad6572008-07-15 17:19:50 +00001405- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1406 incomplete structure was created.

1411
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001412- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001413
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001414- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1415 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001416 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001417 content-length. The problem had been corrected in the 2.4 branch, but never
1418 merged into trunk.
1419
Georg Brandle78fbcc2008-07-05 10:13:36 +00001420- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001433- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1434 handling is now the same as that of other special attributes like __name__).
1435
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001436- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00001958- Issue #2550: The approach used by client/server code for obtaining
1959 ports to listen on in network-oriented tests has been refined in an
1960 effort to facilitate running multiple instances of the entire
1961 regression test suite in parallel without issue.
1962 test_support.bind_port() has been fixed such that it will always
1963 return a unique port -- which wasn't always the case with the
1964 previous implementation, especially if socket options had been set
1965 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1966 new implementation of bind_port() will actually raise an exception
1967 if it is passed an AF_INET/SOCK_STREAM socket with either the
1968 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1969 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1970 the socket it's been passed. This currently only applies to
1971 Windows. This option prevents any other sockets from binding to the
1972 host/port we've bound to, thus removing the possibility of the
1973 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1974 when a second SOCK_STREAM socket binds and accepts to a host/port
1975 that's already been bound by another socket. The optional preferred
1976 port parameter to bind_port() has been removed. Under no
1977 circumstances should tests be hard coding ports!
1978
1979 test_support.find_unused_port() has also been introduced, which will
1980 pass a temporary socket object to bind_port() in order to obtain an
1981 unused port. The temporary socket object is then closed and
1982 deleted, and the port is returned. This method should only be used
1983 for obtaining an unused port in order to pass to an external program
1984 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1985 a parameter to a server-oriented class that doesn't give you direct
1986 access to the underlying socket used.
1987
1988 Finally, test_support.HOST has been introduced, which should be used
1989 for the host argument of any relevant socket calls (i.e. bind and
1990 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001991
1992 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001993 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

1995 test_asynchat and test_socket_ssl.
1996
Georg Brandl3ee81df2008-05-17 18:14:43 +00001997 It is now possible for multiple instances of the regression test
1998 suite to run in parallel without issue.

2265-----------------
2266
Fred Drakea8ee94b2008-03-01 02:45:07 +00002267- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002268 644. The mode is now inherited from the py file.

2271
2272- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002273
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002274- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002275 issue 215555 for a discussion.
2276
Eric Smitha73fbe72008-02-23 03:09:44 +00002277- Added the future_builtins module, which contains hex() and oct().
2278 These are the PEP 3127 version of these functions, designed to be
2279 compatible with the hex() and oct() builtins from Python 3.0. They
2280 differ slightly in their output formats from the existing, unchanged
2281 Python 2.6 builtins. The expected usage of the future_builtins
2282 module is:
2283 from future_builtins import hex, oct
2284
Eric Smith7ef40bf2008-02-20 23:34:22 +00002285- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2286 exponents for exponents with absolute value < 100. Follows C99
2287 standard. This is a change on Windows, which would use 3 digits.
2288 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2289 so that any alterations it does to the resulting string will be
2290 available in stringlib/formatter.h (for float.__format__).
2291
Eric Smith5a3c1352008-02-19 13:21:56 +00002292- Implemented PEP 3101, Advanced String Formatting. This adds a new
2293 builtin format(); a format() method for str and unicode; a
2294 __format__() method to object, str, unicode, int, long, float, and
2295 datetime; the class string.Formatter; and the C API
2296 PyObject_Format().
2297
Georg Brandl3ee81df2008-05-17 18:14:43 +00002298- Fixed several potential crashes, all caused by specially crafted
2299 __del__ methods exploiting objects in temporarily inconsistent
2300 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002301
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002302- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002303 prevent a possible crash: an Abstract Base Class would try to access
2304 a slot on a registered virtual subclass.

2310 in order to allow pymalloc to free more arenas. Python may give back
2311 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002312
Georg Brandl3ee81df2008-05-17 18:14:43 +00002313- Issue #2045: Fix an infinite recursion triggered when printing a
2314 subclass of collections.defaultdict, if its default_factory is set
2315 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002316
Christian Heimesf75dbef2008-02-08 00:11:31 +00002317- Fixed a minor memory leak in dictobject.c. The content of the free
2318 list was not freed on interpreter shutdown.
2319
Georg Brandl3ee81df2008-05-17 18:14:43 +00002320- Limit free list of method and builtin function objects to 256

Georg Brandl3ee81df2008-05-17 18:14:43 +00002323- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2324 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002325 to compact the internal free lists of pre-allocted ints and floats.
2326
Georg Brandl3ee81df2008-05-17 18:14:43 +00002327- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2328 calls. Python expected the return type int but the fork familie
2329 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002330

Georg Brandl3ee81df2008-05-17 18:14:43 +00002343- Patch #1473257: generator objects gain a gi_code attribute. This is
2344 the same object as the func_code attribute of the function that
2345 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002346
Georg Brandl3ee81df2008-05-17 18:14:43 +00002347- Issue #1920: "while 0" statements were completely removed by the
2348 compiler, even in the presence of an "else" clause, which is
2349 supposed to be run when the condition is false. Now the compiler
2350 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002351

Georg Brandl3ee81df2008-05-17 18:14:43 +00002378- Objects/structseq.c: Implemented new structseq representation. The
2379 patch makes structseqs (e.g. the return value of os.stat) more
2380 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002381
Georg Brandl3ee81df2008-05-17 18:14:43 +00002382- Patch #1700288: added a type attribute cache that caches method
2383 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002384
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002385- Bug #1776: __import__() no longer accepts filenames on any platform.
2386 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00002388- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2389
Georg Brandl3ee81df2008-05-17 18:14:43 +00002390- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2391 envvar and sys.dont_write_bytecode attribute. All these can be set
2392 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002393
Georg Brandl3ee81df2008-05-17 18:14:43 +00002394- Improve some exception messages when Windows fails to load an
2395 extension module. Now we get for example '%1 is not a valid Win32
2396 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002397

Christian Heimes0a8143f2007-12-18 23:22:54 +00002403- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002404 and INF. float("nan"), float("inf") and float("-inf") now work on
2405 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002407- Compiler now generates simpler and faster code for dictionary
2408 literals. The oparg for BUILD_MAP now indicates an estimated
2409 dictionary size. There is a new opcode, STORE_MAP, for adding
2410 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002439- Patch #1739468: Directories and zipfiles containing a __main__.py
2440 file can now be directly executed by passing their name to the
2441 interpreter. The directory/zipfile is automatically inserted as the
2442 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002444- Issue #1265: Fix a problem with sys.settrace, if the tracing
2445 function uses a generator expression when at the same time the
2446 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002447
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002448- sets and frozensets now have an isdisjoint() method.

2451
Neal Norwitz44f326e2007-10-05 05:29:17 +00002452- Fix warnings found by the new version of the Coverity checker.
2453
Georg Brandl3ee81df2008-05-17 18:14:43 +00002454- The enumerate() builtin function is no longer bounded to sequences
2455 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2456 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002457
Georg Brandl3ee81df2008-05-17 18:14:43 +00002458- Issue #1686386: Tuple's tp_repr did not take into account the
2459 possibility of having a self-referential tuple, which is possible
2460 from C code. Nor did object's tp_str consider that a type's tp_str
2461 could do something that could lead to an inifinite recursion.
2462 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2463 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002464
Georg Brandl3ee81df2008-05-17 18:14:43 +00002465- Issue #1164: It was possible to trigger deadlock when using the
2466 'print' statement to write to a file since the GIL was not released
2467 as needed. Now PyObject_Print() does the right thing along with
2468 various tp_print implementations of the built-in types and those in
2469 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002470
Georg Brandl3ee81df2008-05-17 18:14:43 +00002471- Issue #1147: Exceptions were directly allowing string exceptions in
2472 their throw() method even though string exceptions no longer
2473 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00002477
Brett Cannon1e534b52007-09-07 04:18:30 +00002478- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002479 PyObject_Call() never calling back out to Python code to trigger
2480 recursion depth updates/checks. Required the creation of a static
2481 RuntimeError instance in case normalizing an exception put the
2482 recursion check value past its limit. Fixes crashers
2483 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002484

Neal Norwitz0ac60192007-05-27 04:08:54 +00002498- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002499 __*__ attributes. (Some already existed, e.g., __doc__ and
2500 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002501
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002502- Add -3 option to the interpreter to warn about features that are
2503 deprecated and will be changed/removed in Python 3.0.
2504
Georg Brandl2134e752007-05-21 20:34:16 +00002505- Patch #1686487: you can now pass any mapping after '**' in function
2506 calls.
2507
Collin Winter62903052007-05-18 23:11:24 +00002508- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002509 "except E as target:". This is to provide forwards compatibility
2510 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002511
Brett Cannon229cee22007-05-05 01:34:02 +00002512- Deprecate BaseException.message as per PEP 352.

2516
Vinay Sajip8549ce32007-05-06 17:53:37 +00002517- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002518 setting a plain string, ie don't expand to single letter identifiers.
2519
Raymond Hettinger13936692007-04-11 18:40:58 +00002520- Request #1191699: Slices can now be pickled.
2521
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002522- Request #1193128: str.translate() now allows a None argument for
2523 translations that only remove characters without re-mapping the
2524 remaining characters.
2525
Georg Brandl5cb76c12007-03-21 09:00:39 +00002526- Patch #1682205: a TypeError while unpacking an iterable is no longer
2527 masked by a generic one with the message "unpack non-sequence".
2528
Neal Norwitzaa754b72007-03-21 06:39:48 +00002529- Remove unused file Python/fmod.c.
2530
Guido van Rossum143b5642007-03-23 04:58:42 +00002531- Bug #1683368: The object.__init__() and object.__new__() methods are
2532 now stricter in rejecting excess arguments. The only time when
2533 either allows excess arguments is when it is not overridden and the
2534 other one is. For backwards compatibility, when both are
2535 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002536 warning later). Also, type.__init__() insists on the same signature
2537 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002538
Georg Brandl3ee81df2008-05-17 18:14:43 +00002539- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2540 object to complex using its __complex__() method before falling back
2541 to the __float__() method. Therefore, the functions in the cmath
2542 module now can operate on objects that define a __complex__()
2543 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002544
Georg Brandl3ee81df2008-05-17 18:14:43 +00002545- Patch #1623563: allow __class__ assignment for classes with
2546 __slots__. The old and the new class are still required to have the
2547 same slot names.

2560
Georg Brandl7b9c5552007-03-12 14:30:05 +00002561- Bug #1678647: write a newline after printing an exception in any
2562 case, even when converting the value to a string failed.
2563
Georg Brandl871f1bc2007-03-12 13:17:36 +00002564- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002565 its argument, if it exists. If not, it will work like before. This
2566 allows customizing the output of dir() in the presence of a
2567 __getattr__().

2576 parthensized forms. This means complex(repr(x)) now works instead of
2577 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002578
Georg Brandlaa2321b2007-03-07 00:40:28 +00002579- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002580 makes the filenames the warning module prints much more sensible
2581 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002582

Georg Brandl0fca97a2007-03-05 22:28:08 +00002594- Patch #1674228: when assigning a slice (old-style), check for the
2595 sq_ass_slice instead of the sq_slice slot.
2596
Georg Brandl3ee81df2008-05-17 18:14:43 +00002597- When printing an unraisable error, don't print exceptions. before
2598 the name. This duplicates the behavior whening normally printing
2599 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003132 AttributeError instead of an IOError when the server's response
3133 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003134

Georg Brandl3ee81df2008-05-17 18:14:43 +00003139- Patch #1429539: pdb now correctly initializes the __main__ module
3140 for the debugged script, which means that imports from __main__ work

3149
Georg Brandl3ee81df2008-05-17 18:14:43 +00003150- Patch #1530482: add pydoc.render_doc() which returns the

3165
Georg Brandl92a6bae2007-03-13 17:43:32 +00003166- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003167 are set for invalid interpolation sequences that would lead to
3168 errors on reading back those values.

3211 returned string up to the first NUL character.

3222
Georg Brandl3ee81df2008-05-17 18:14:43 +00003223- unittest now verifies more of its assumptions. In particular,
3224 TestCase and TestSuite subclasses (not instances) are no longer
3225 accepted in TestSuite.addTest(). This should cause no
3226 incompatibility since it never made sense with ordinary subclasses
3227 -- the failure just occurred later, with a more cumbersome
3228 exception.

3599 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3600 silently miscode subclasses of those types. Now, it raises a

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003616- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00003617 time so that opening a database previously created with the DB_DUP
3618 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3619 opens. Specifically: dictionary assignment to a DB object will
3620 replace all values for a given key when the database allows
3621 duplicate values. DB users should use DB.put(k, v) when they want
3622 to store duplicates; not DB[k] = v.

3629 characters with ASCII value less than 32. Also, it correctly quotes
3630 dots only if they occur on a single line, as opposed to the previous
3631 behavior of quoting dots if they are the second character of any
3632 line.

3978 of w# format code incorrectly truncated the length to an int, even
3979 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3980 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004010- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4011 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
