758What's New in Python 2.6.1
759==========================
760
761*Release date: 04-Dec-2008*
762
763Core and Builtins
764-----------------
765
766- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
767 interpreter to abort ("Fatal Python error: Could not reset the stack!")
768 instead of throwing a MemoryError.
769
770- Issue #4367: Python would segfault during compiling when the unicodedata
771 module couldn't be imported and \N escapes were present.
772
773- Issue #4348: Some bytearray methods returned that didn't cause any change to
774 the bytearray, returned the same bytearray instead of a copy.
775
776- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
777
778- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
779
780- Issue #4048: The parser module now correctly validates relative imports.
781
782- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
783 exec statement.
784
785- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``

787
788- Issue #4209: Enabling unicode_literals and the print_function in the same
789 __future__ import didn't work.
790
791- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
792 returned a path longer than MAX_PATH. (But It's doubtful this code path is
793 really executed because I cannot move to such directory on win2k)
794
795- Issue #4069: When set.remove(element) is used with a set element, the element
796 is temporarily replaced with an equivalent frozenset. But the eventual
797 KeyError would always report the empty frozenset([]) as the missing key. Now
798 it correctly refers to the initial element.
799
800- Fixed C99 style comments in several files. Python is now C89 compatible
801 again.

949
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000950- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
951 PyString_FromFormat or PyErr_Format to display size_t values. The macro
952 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
953 ``printf`` function, whereas PyString_FromFormat has an independent

955 This makes a difference on win64, where ``printf`` needs "%Id" to display
956 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +0000976 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
977 mechanism. In the process, fix a bug where isinstance() and issubclass(),

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001116What's New in Python 2.6 beta 3?
1117================================
1118
Barry Warsaw07a4a382008-08-21 01:15:08 +00001119*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001120
1121Core and Builtins
1122-----------------
1123
Guido van Rossumf8402962008-08-20 15:01:50 +00001124- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1125 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1126 extensions do not automatically benefit from the class attribute
1127 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1128 to their tp_flags field if they care. This is a backwards
1129 compatibility feature; in 3.0, all types will use the cache by
1130 default.
1131
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001132- Keyword arguments can now follow starred arguments. (``f(a, *args,
1133 keyword=23)`` is now valid syntax.)
1134
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001135- ctypes function pointers that are COM methods have a boolean True
1136 value again.
1137
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001138- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1139 by denying s# to parse objects that have a releasebuffer procedure,
1140 and introducing s*.
1141
Georg Brandl1e13ea92008-08-11 09:07:59 +00001142- Issue #3537: Fix an assertion failure when an empty but presized dict
1143 object was stored in the freelist.
1144
Mark Dickinsonb6467572008-08-04 21:30:09 +00001145- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1146 ValueError consistently across platforms.
1147
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001148- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1149 (64bit Unix, for example), unichr() would truncate its argument and return
1150 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1151
Neal Norwitze7d8be82008-07-31 17:17:14 +00001152- Apply security patches from Apple.
1153
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001154- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1155 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1156
Antoine Pitrou92f82162008-07-25 22:22:08 +00001157- Issue #1819: function calls with several named parameters are now on
1158 average 35% faster (as measured by pybench).
1159
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001160- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1161 the python debugger steps into a class statement: the free variables (local
1162 variables defined in an outer scope) would be deleted from the outer scope.
1163
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001164- Issue #2620: Overflow checking when allocating or reallocating memory
1165 was not always being done properly in some python types and extension
1166 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1167 all been updated to perform better checks and places in the code that
1168 would previously leak memory on the error path when such an allocation
1169 failed have been fixed.

1172-------
1173
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001174- Issue #3612: Added some missing basic types in ctypes.wintypes.
1175
Benjamin Petersone977ad42008-08-20 01:42:01 +00001176- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1177 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1178
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001179- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1180 version reported by these tools does not necessarily follow the python
1181 version numbering scheme, so the module is less strict when parsing it.
1182
Nick Coghlanf70385a2008-08-18 12:42:46 +00001183- Issue #2235: Added Py3k warnings for types which will become unhashable
1184 under the stricter __hash__ inheritance rules in 3.0. Several types
1185 which did not meet the rules for hash invariants and were already
1186 unhashable in 3.0 have now been explicitly flagged as unhashable in
1187 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1188 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1189
Brett Cannon88f801d2008-08-18 00:46:22 +00001190- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1191 imported into the module but exposed as part of the module's API.
1192

1194
Brett Cannon46225e72008-08-18 00:36:52 +00001195- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001197- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1198
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001199- Issue #3575: Incremental decoder's decode function now takes bytearray
1200 by using 's*' instead of 't#'.
1201
Jesus Cea585ad8a2009-07-02 15:37:21 +00001202- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001203 fails unicode conversion on 2nd parameter. (windows only)
1204
Facundo Batista94f243a2008-08-17 03:38:39 +00001205- Issue 2464. urllib2 now supports a malformation in the URL received
1206 in a redirect.
1207
Brett Cannonabe423e2008-08-16 21:47:07 +00001208- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001209 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001210
Facundo Batistaeb90b782008-08-16 14:44:07 +00001211- Issue #2776: fixed small issue when handling an URL with double slash
1212 after a 302 response in the case of not going through a proxy.
1213
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001214- Issue #2676: in the email package, content-type parsing was hanging on
1215 pathological input because of quadratic or exponential behaviour of a
1216 regular expression.
1217
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001218- Issue #3476: binary buffered reading through the new "io" library is now
1219 thread-safe.
1220
Brett Cannonbf3157b2008-08-14 05:00:03 +00001221- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1222 since mimetools itself is deprecated. Because modules are cached, all
1223 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1224
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001225- Issue #3134: shutil referenced undefined WindowsError symbol.
1226
Robert Schuppenies14646332008-08-10 11:01:53 +00001227- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1228 menu entries were not deleted.
1229
Brett Cannon83e81842008-08-09 23:30:55 +00001230- Copied the implementation of reduce() to _functools.reduce() to have a
1231 version that did not raise a DeprecationWarning under -3.
1232
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001233- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1234 a MemoryError rather than silently stop the iteration.
1235
Guido van Rossum59ce9012008-08-09 14:55:34 +00001236- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1237 to _sre.compile() will now be rejected. This should not affect anybody
1238 since the re.compile() function never generates invalid re-bytecode.
1239
Skip Montanaroa032bf42008-08-08 22:52:51 +00001240- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

1242 it wasn't initialized during instantiation.
1243
Brett Cannon3aa2a492008-08-06 22:28:09 +00001244- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1245 the reload() built-in has been removed.
1246
Brett Cannon7e30b672008-08-04 21:52:25 +00001247- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001248 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001259 asking for a specific length. This problem only affected files opened
1260 using the new "io" module, not the built-in open() function.

1286 file name rather than a ZipInfo instance, so files are extracted with
1287 mode 0600 rather than 000 under Unix.
1288
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001289- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001301- Issue #2235: the C API function PyObject_HashNotImplemented and its
1302 interaction with the tp_hash slot (added in 2.6b2) are now documented
1303
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001304- Issue #643841: The language reference now provides more detailed
1305 coverage of the lookup process for special methods. The disclaimers
1306 regarding lack of coverage of new-style classes have also been
1307 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001310What's New in Python 2.6 beta 2?
1311================================
1312
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001313*Release date: 17-Jul-2008*
1314
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001315Core and Builtins
1316-----------------
1317
Georg Brandl3e483f62008-07-16 22:57:41 +00001318- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1319 its methods now allow for items objects that can be converted to
1320 an integer using operator.index().
1321
Mark Dickinson64b7e502008-07-16 09:40:03 +00001322- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1323 produced a ValueError instead of giving the correct float.
1324
Eric Smitha5fa5a22008-07-16 00:11:49 +00001325- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1326 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1327
Mark Dickinson7103aa42008-07-15 19:08:33 +00001328- Issue #3008: the float type has a new instance method 'float.hex'
1329 and a new class method 'float.fromhex' to convert floating-point
1330 numbers to and from hexadecimal strings, respectively.
1331
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001332- Issue #2235: __hash__ is once again inherited by default. To allow
1333 collections.Hashable to remain meaningful in the presence of the
1334 default hash implementation (object.__hash__), it is now possible
1335 to explicit block inheritance of hash by setting __hash__=None at
1336 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1337 level.
1338
Nick Coghlanb028f502008-07-13 14:52:36 +00001339- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1340 the parent module cannot be found while performing an absolute import.
1341 This means that an incorrectly defined __package__ attribute will
1342 now only prevent relative imports in that module rather than causing
1343 all imports from that module to fail.
1344
Nick Coghlan14ff9942008-07-08 14:21:42 +00001345- Issue #2517: Allow unicode messages in Exceptions again by correctly
1346 bypassing the instance dictionary when looking up __unicode__ on
1347 new-style classes.
1348
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001349- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1350 set to a custom object whose write() method happens to install
1351 another file in sys.stdout.
1352
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001353- Issue #3088: Corrected a race condition in classes derived from
1354 threading.local: the first member set by a thread could be saved in
1355 another thread's dictionary.
1356
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001357- Issue #3004: Minor change to slice.indices(): the start and stop
1358 arguments are now treated identically, making the behaviour easier
1359 to describe and understand. For example, slice(None, -10,
1360 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1361 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1362 10, -1).
1363
Georg Brandl278fc502008-07-19 12:46:12 +00001364- Issue #3219: Calling a function with repeated keyword arguments,
1365 f(a=2, a=23), would not cause a syntax error. This was a regression
1366 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001367
Georg Brandl278fc502008-07-19 12:46:12 +00001368- Issue #2862: Make int and float freelist management consistent with
1369 other freelists. Changes their CompactFreeList apis into
1370 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001371

1373-------
1374
Thomas Heller57adf222008-08-14 19:10:48 +00001375- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1376 api functions without holding the GIL, which could lead to a fatal
1377 error when they failed.
1378
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001379- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001387- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1388 ForkingPickler.register() to resolve conflict with ctypes.
1389
Vinay Sajip51e65192008-07-18 09:01:10 +00001390- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001391
Thomas Heller880f5292008-07-15 19:39:38 +00001392- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1393 a valid dlerror() message.
1394
Thomas Heller2bad6572008-07-15 17:19:50 +00001395- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1396 incomplete structure was created.
1397

1401
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001402- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001403
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001404- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1405 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001406 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001407 content-length. The problem had been corrected in the 2.4 branch, but never
1408 merged into trunk.
1409
Georg Brandle78fbcc2008-07-05 10:13:36 +00001410- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00001418 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00001419
Vinay Sajip51e65192008-07-18 09:01:10 +00001420- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001421 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00001422
Nick Coghlanc060b0e2008-07-02 13:09:19 +00001423- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1424 handling is now the same as that of other special attributes like __name__).
1425
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001426- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
1427 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00001878- Issue #1631171: Re-implement the 'warnings' module in C (the
1879 original Python code has been kept as backup). This will allow for
1880 using the 'warning's machinery in such places as the parser where
1881 use of pure Python code is not possible. Both the ``showarning()``
1882 and ``formatwarning()`` gain an optional 'line' argument which is
1883 not called by default for backwards-compatibility reasons. Setting
1884 ``warnings.showwarning()`` to an implementation that lacks support
1885 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001948- Issue #2550: The approach used by client/server code for obtaining
1949 ports to listen on in network-oriented tests has been refined in an
1950 effort to facilitate running multiple instances of the entire
1951 regression test suite in parallel without issue.
1952 test_support.bind_port() has been fixed such that it will always
1953 return a unique port -- which wasn't always the case with the
1954 previous implementation, especially if socket options had been set
1955 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1956 new implementation of bind_port() will actually raise an exception
1957 if it is passed an AF_INET/SOCK_STREAM socket with either the
1958 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1959 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1960 the socket it's been passed. This currently only applies to
1961 Windows. This option prevents any other sockets from binding to the
1962 host/port we've bound to, thus removing the possibility of the
1963 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1964 when a second SOCK_STREAM socket binds and accepts to a host/port
1965 that's already been bound by another socket. The optional preferred
1966 port parameter to bind_port() has been removed. Under no
1967 circumstances should tests be hard coding ports!
1968
1969 test_support.find_unused_port() has also been introduced, which will
1970 pass a temporary socket object to bind_port() in order to obtain an
1971 unused port. The temporary socket object is then closed and
1972 deleted, and the port is returned. This method should only be used
1973 for obtaining an unused port in order to pass to an external program
1974 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1975 a parameter to a server-oriented class that doesn't give you direct
1976 access to the underlying socket used.
1977
1978 Finally, test_support.HOST has been introduced, which should be used
1979 for the host argument of any relevant socket calls (i.e. bind and
1980 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001981
1982 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001983 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001984 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1985 test_asynchat and test_socket_ssl.
1986
Georg Brandl3ee81df2008-05-17 18:14:43 +00001987 It is now possible for multiple instances of the regression test
1988 suite to run in parallel without issue.

2255-----------------
2256
Fred Drakea8ee94b2008-03-01 02:45:07 +00002257- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002258 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002260- Issue #2067: file.__exit__() now calls subclasses' close() method.
2261
2262- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002263
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002264- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002265 issue 215555 for a discussion.
2266
Eric Smitha73fbe72008-02-23 03:09:44 +00002267- Added the future_builtins module, which contains hex() and oct().
2268 These are the PEP 3127 version of these functions, designed to be
2269 compatible with the hex() and oct() builtins from Python 3.0. They
2270 differ slightly in their output formats from the existing, unchanged
2271 Python 2.6 builtins. The expected usage of the future_builtins
2272 module is:
2273 from future_builtins import hex, oct
2274
Eric Smith7ef40bf2008-02-20 23:34:22 +00002275- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2276 exponents for exponents with absolute value < 100. Follows C99
2277 standard. This is a change on Windows, which would use 3 digits.
2278 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2279 so that any alterations it does to the resulting string will be
2280 available in stringlib/formatter.h (for float.__format__).
2281
Eric Smith5a3c1352008-02-19 13:21:56 +00002282- Implemented PEP 3101, Advanced String Formatting. This adds a new
2283 builtin format(); a format() method for str and unicode; a
2284 __format__() method to object, str, unicode, int, long, float, and
2285 datetime; the class string.Formatter; and the C API
2286 PyObject_Format().
2287
Georg Brandl3ee81df2008-05-17 18:14:43 +00002288- Fixed several potential crashes, all caused by specially crafted
2289 __del__ methods exploiting objects in temporarily inconsistent
2290 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002291
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002292- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002293 prevent a possible crash: an Abstract Base Class would try to access
2294 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002295

Georg Brandl3ee81df2008-05-17 18:14:43 +00002299- Clear all free lists during a gc.collect() of the highest generation
2300 in order to allow pymalloc to free more arenas. Python may give back
2301 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002302
Georg Brandl3ee81df2008-05-17 18:14:43 +00002303- Issue #2045: Fix an infinite recursion triggered when printing a
2304 subclass of collections.defaultdict, if its default_factory is set
2305 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002306
Christian Heimesf75dbef2008-02-08 00:11:31 +00002307- Fixed a minor memory leak in dictobject.c. The content of the free
2308 list was not freed on interpreter shutdown.
2309
Georg Brandl3ee81df2008-05-17 18:14:43 +00002310- Limit free list of method and builtin function objects to 256
2311 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002313- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2314 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002315 to compact the internal free lists of pre-allocted ints and floats.
2316
Georg Brandl3ee81df2008-05-17 18:14:43 +00002317- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2318 calls. Python expected the return type int but the fork familie
2319 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002320
Georg Brandl3ee81df2008-05-17 18:14:43 +00002321- Issue #1678380: Fix a bug that identifies 0j and -0j when they

2331 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002332
Georg Brandl3ee81df2008-05-17 18:14:43 +00002333- Patch #1473257: generator objects gain a gi_code attribute. This is
2334 the same object as the func_code attribute of the function that
2335 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002336
Georg Brandl3ee81df2008-05-17 18:14:43 +00002337- Issue #1920: "while 0" statements were completely removed by the
2338 compiler, even in the presence of an "else" clause, which is
2339 supposed to be run when the condition is false. Now the compiler
2340 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002341
Guido van Rossumeead05f2008-01-24 18:21:02 +00002342- A few crashers fixed: weakref_in_del.py (issue #1377858);

2344 borrowed_ref_[34].py (not in tracker).
2345
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002346- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002347 suppressed while an extension is loaded by calling SetErrorMode in

2349
Georg Brandl3ee81df2008-05-17 18:14:43 +00002350- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002351 several extension methods and modules do not work without unicode
2352 support.
2353
Georg Brandl26543b12008-01-21 18:36:51 +00002354- Issue #1882: when compiling code from a string, encoding cookies in the
2355 second line of code were not always recognized correctly.
2356
Georg Brandl14404b62008-01-19 19:27:05 +00002357- Issue #1679: "0x" was taken as a valid integer literal.
2358
Georg Brandl6caad7d2008-01-26 14:19:22 +00002359- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002360 added.
2361
Christian Heimesc94e2b52008-01-14 04:13:37 +00002362- sys.float_info / PyFloat_GetInfo: The floating point information
2363 object was converted from a dict to a specialized structseq object.
2364
Georg Brandl3ee81df2008-05-17 18:14:43 +00002365- Patch #1816: Added sys.flags structseq. It exposes the status of
2366 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002367
Georg Brandl3ee81df2008-05-17 18:14:43 +00002368- Objects/structseq.c: Implemented new structseq representation. The
2369 patch makes structseqs (e.g. the return value of os.stat) more
2370 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002371

Georg Brandl3ee81df2008-05-17 18:14:43 +00002384- Improve some exception messages when Windows fails to load an
2385 extension module. Now we get for example '%1 is not a valid Win32
2386 application' instead of 'error code 193'.

2399 dictionary size. There is a new opcode, STORE_MAP, for adding
2400 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002429- Patch #1739468: Directories and zipfiles containing a __main__.py
2430 file can now be directly executed by passing their name to the
2431 interpreter. The directory/zipfile is automatically inserted as the
2432 first entry in sys.path.

2443
Georg Brandl3ee81df2008-05-17 18:14:43 +00002444- The enumerate() builtin function is no longer bounded to sequences
2445 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2446 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002447
Georg Brandl3ee81df2008-05-17 18:14:43 +00002448- Issue #1686386: Tuple's tp_repr did not take into account the
2449 possibility of having a self-referential tuple, which is possible
2450 from C code. Nor did object's tp_str consider that a type's tp_str
2451 could do something that could lead to an inifinite recursion.
2452 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2453 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002454
Georg Brandl3ee81df2008-05-17 18:14:43 +00002455- Issue #1164: It was possible to trigger deadlock when using the
2456 'print' statement to write to a file since the GIL was not released
2457 as needed. Now PyObject_Print() does the right thing along with
2458 various tp_print implementations of the built-in types and those in
2459 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00002468- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002469 PyObject_Call() never calling back out to Python code to trigger
2470 recursion depth updates/checks. Required the creation of a static
2471 RuntimeError instance in case normalizing an exception put the
2472 recursion check value past its limit. Fixes crashers

Georg Brandl3ee81df2008-05-17 18:14:43 +00002489 __*__ attributes. (Some already existed, e.g., __doc__ and
2490 __name__.)

2496 calls.
2497
Collin Winter62903052007-05-18 23:11:24 +00002498- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002499 "except E as target:". This is to provide forwards compatibility
2500 with Python 3.0.

2506
Vinay Sajip8549ce32007-05-06 17:53:37 +00002507- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002508 setting a plain string, ie don't expand to single letter identifiers.
2509
Raymond Hettinger13936692007-04-11 18:40:58 +00002510- Request #1191699: Slices can now be pickled.
2511
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002512- Request #1193128: str.translate() now allows a None argument for

2514 remaining characters.
2515
Georg Brandl5cb76c12007-03-21 09:00:39 +00002516- Patch #1682205: a TypeError while unpacking an iterable is no longer

2520
Guido van Rossum143b5642007-03-23 04:58:42 +00002521- Bug #1683368: The object.__init__() and object.__new__() methods are
2522 now stricter in rejecting excess arguments. The only time when
2523 either allows excess arguments is when it is not overridden and the
2524 other one is. For backwards compatibility, when both are
2525 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002526 warning later). Also, type.__init__() insists on the same signature
2527 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002528
Georg Brandl3ee81df2008-05-17 18:14:43 +00002529- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2530 object to complex using its __complex__() method before falling back
2531 to the __float__() method. Therefore, the functions in the cmath
2532 module now can operate on objects that define a __complex__()
2533 method.

2550
Georg Brandl7b9c5552007-03-12 14:30:05 +00002551- Bug #1678647: write a newline after printing an exception in any
2552 case, even when converting the value to a string failed.
2553
Georg Brandl871f1bc2007-03-12 13:17:36 +00002554- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002555 its argument, if it exists. If not, it will work like before. This
2556 allows customizing the output of dir() in the presence of a
2557 __getattr__().

2567 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002568
Georg Brandlaa2321b2007-03-07 00:40:28 +00002569- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002570 makes the filenames the warning module prints much more sensible
2571 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002572

2586
Georg Brandl3ee81df2008-05-17 18:14:43 +00002587- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00003122 AttributeError instead of an IOError when the server's response
3123 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003124

Georg Brandl3ee81df2008-05-17 18:14:43 +00003140- Patch #1530482: add pydoc.render_doc() which returns the

3155
Georg Brandl92a6bae2007-03-13 17:43:32 +00003156- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003157 are set for invalid interpolation sequences that would lead to
3158 errors on reading back those values.

3201 returned string up to the first NUL character.

3212
Georg Brandl3ee81df2008-05-17 18:14:43 +00003213- unittest now verifies more of its assumptions. In particular,
3214 TestCase and TestSuite subclasses (not instances) are no longer
3215 accepted in TestSuite.addTest(). This should cause no
3216 incompatibility since it never made sense with ordinary subclasses
3217 -- the failure just occurred later, with a more cumbersome
3218 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003607 time so that opening a database previously created with the DB_DUP
3608 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3609 opens. Specifically: dictionary assignment to a DB object will
3610 replace all values for a given key when the database allows
3611 duplicate values. DB users should use DB.put(k, v) when they want
3612 to store duplicates; not DB[k] = v.

3621 behavior of quoting dots if they are the second character of any
3622 line.

3968 of w# format code incorrectly truncated the length to an int, even
3969 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3970 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004000- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4001 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
