735What's New in Python 2.6.1
736==========================
737
738*Release date: 04-Dec-2008*
739
740Core and Builtins
741-----------------
742
743- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
744 interpreter to abort ("Fatal Python error: Could not reset the stack!")
745 instead of throwing a MemoryError.
746
747- Issue #4367: Python would segfault during compiling when the unicodedata
748 module couldn't be imported and \N escapes were present.
749
750- Issue #4348: Some bytearray methods returned that didn't cause any change to
751 the bytearray, returned the same bytearray instead of a copy.
752
753- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
754
755- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
756
757- Issue #4048: The parser module now correctly validates relative imports.
758
759- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

761
762- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
763 method does not return iterators for the 4th and 5th items.
764
765- Issue #4209: Enabling unicode_literals and the print_function in the same
766 __future__ import didn't work.
767
768- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
769 returned a path longer than MAX_PATH. (But It's doubtful this code path is
770 really executed because I cannot move to such directory on win2k)
771
772- Issue #4069: When set.remove(element) is used with a set element, the element
773 is temporarily replaced with an equivalent frozenset. But the eventual
774 KeyError would always report the empty frozenset([]) as the missing key. Now
775 it correctly refers to the initial element.
776
777- Fixed C99 style comments in several files. Python is now C89 compatible
778 again.

929
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000930- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
931 PyString_FromFormat or PyErr_Format to display size_t values. The macro
932 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
933 ``printf`` function, whereas PyString_FromFormat has an independent

935 This makes a difference on win64, where ``printf`` needs "%Id" to display

1031 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1032 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001055- Issue #2975: When compiling several extension modules with Visual Studio 2008
1056 from the same python interpreter, some environment variables would grow
1057 without limit.
1058
Benjamin Peterson37346b22008-08-23 20:27:43 +00001059- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001096What's New in Python 2.6 beta 3?
1097================================
1098
Barry Warsaw07a4a382008-08-21 01:15:08 +00001099*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001100
1101Core and Builtins
1102-----------------
1103
Guido van Rossumf8402962008-08-20 15:01:50 +00001104- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1105 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1106 extensions do not automatically benefit from the class attribute
1107 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1108 to their tp_flags field if they care. This is a backwards
1109 compatibility feature; in 3.0, all types will use the cache by
1110 default.
1111
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001112- Keyword arguments can now follow starred arguments. (``f(a, *args,
1113 keyword=23)`` is now valid syntax.)
1114
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001115- ctypes function pointers that are COM methods have a boolean True
1116 value again.
1117
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001118- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1119 by denying s# to parse objects that have a releasebuffer procedure,
1120 and introducing s*.
1121
Georg Brandl1e13ea92008-08-11 09:07:59 +00001122- Issue #3537: Fix an assertion failure when an empty but presized dict
1123 object was stored in the freelist.
1124
Mark Dickinsonb6467572008-08-04 21:30:09 +00001125- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1126 ValueError consistently across platforms.
1127
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001128- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1129 (64bit Unix, for example), unichr() would truncate its argument and return
1130 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1131
Neal Norwitze7d8be82008-07-31 17:17:14 +00001132- Apply security patches from Apple.
1133
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001134- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1135 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1136
Antoine Pitrou92f82162008-07-25 22:22:08 +00001137- Issue #1819: function calls with several named parameters are now on
1138 average 35% faster (as measured by pybench).
1139
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001140- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1141 the python debugger steps into a class statement: the free variables (local
1142 variables defined in an outer scope) would be deleted from the outer scope.
1143
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001144- Issue #2620: Overflow checking when allocating or reallocating memory
1145 was not always being done properly in some python types and extension
1146 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1147 all been updated to perform better checks and places in the code that
1148 would previously leak memory on the error path when such an allocation
1149 failed have been fixed.

1152-------
1153
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001154- Issue #3612: Added some missing basic types in ctypes.wintypes.
1155
Benjamin Petersone977ad42008-08-20 01:42:01 +00001156- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1157 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1158
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001159- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1160 version reported by these tools does not necessarily follow the python
1161 version numbering scheme, so the module is less strict when parsing it.
1162
Nick Coghlanf70385a2008-08-18 12:42:46 +00001163- Issue #2235: Added Py3k warnings for types which will become unhashable
1164 under the stricter __hash__ inheritance rules in 3.0. Several types
1165 which did not meet the rules for hash invariants and were already
1166 unhashable in 3.0 have now been explicitly flagged as unhashable in
1167 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1168 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1169
Brett Cannon88f801d2008-08-18 00:46:22 +00001170- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1171 imported into the module but exposed as part of the module's API.
1172
Brett Cannon7b96f072008-08-18 00:41:11 +00001173- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1174
Brett Cannon46225e72008-08-18 00:36:52 +00001175- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1176
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001177- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1178
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001179- Issue #3575: Incremental decoder's decode function now takes bytearray
1180 by using 's*' instead of 't#'.
1181
Jesus Cea585ad8a2009-07-02 15:37:21 +00001182- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001183 fails unicode conversion on 2nd parameter. (windows only)
1184
Facundo Batista94f243a2008-08-17 03:38:39 +00001185- Issue 2464. urllib2 now supports a malformation in the URL received
1186 in a redirect.
1187
Brett Cannonabe423e2008-08-16 21:47:07 +00001188- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001189 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001190
Facundo Batistaeb90b782008-08-16 14:44:07 +00001191- Issue #2776: fixed small issue when handling an URL with double slash
1192 after a 302 response in the case of not going through a proxy.
1193
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001194- Issue #2676: in the email package, content-type parsing was hanging on
1195 pathological input because of quadratic or exponential behaviour of a
1196 regular expression.
1197
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001198- Issue #3476: binary buffered reading through the new "io" library is now
1199 thread-safe.
1200
Brett Cannonbf3157b2008-08-14 05:00:03 +00001201- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1202 since mimetools itself is deprecated. Because modules are cached, all
1203 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1204
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001205- Issue #3134: shutil referenced undefined WindowsError symbol.
1206
Robert Schuppenies14646332008-08-10 11:01:53 +00001207- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1208 menu entries were not deleted.
1209
Brett Cannon83e81842008-08-09 23:30:55 +00001210- Copied the implementation of reduce() to _functools.reduce() to have a
1211 version that did not raise a DeprecationWarning under -3.
1212
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001213- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1214 a MemoryError rather than silently stop the iteration.
1215
Guido van Rossum59ce9012008-08-09 14:55:34 +00001216- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1217 to _sre.compile() will now be rejected. This should not affect anybody
1218 since the re.compile() function never generates invalid re-bytecode.
1219
Skip Montanaroa032bf42008-08-08 22:52:51 +00001220- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1221 upon first access it can be automatically initialized from the csv file if
1222 it wasn't initialized during instantiation.
1223
Brett Cannon3aa2a492008-08-06 22:28:09 +00001224- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1225 the reload() built-in has been removed.
1226
Brett Cannon7e30b672008-08-04 21:52:25 +00001227- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001228 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001239 asking for a specific length. This problem only affected files opened
1240 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001241

Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001269- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1270 argument in python 2.5, this broke code that subclassed Popen to include its
1271 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1282 interaction with the tp_hash slot (added in 2.6b2) are now documented
1283
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001284- Issue #643841: The language reference now provides more detailed
1285 coverage of the lookup process for special methods. The disclaimers
1286 regarding lack of coverage of new-style classes have also been
1287 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001290What's New in Python 2.6 beta 2?
1291================================
1292
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001293*Release date: 17-Jul-2008*
1294
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001295Core and Builtins
1296-----------------
1297
Georg Brandl3e483f62008-07-16 22:57:41 +00001298- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1299 its methods now allow for items objects that can be converted to
1300 an integer using operator.index().
1301
Mark Dickinson64b7e502008-07-16 09:40:03 +00001302- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1303 produced a ValueError instead of giving the correct float.
1304
Eric Smitha5fa5a22008-07-16 00:11:49 +00001305- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1306 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1307
Mark Dickinson7103aa42008-07-15 19:08:33 +00001308- Issue #3008: the float type has a new instance method 'float.hex'
1309 and a new class method 'float.fromhex' to convert floating-point
1310 numbers to and from hexadecimal strings, respectively.
1311
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001312- Issue #2235: __hash__ is once again inherited by default. To allow
1313 collections.Hashable to remain meaningful in the presence of the
1314 default hash implementation (object.__hash__), it is now possible
1315 to explicit block inheritance of hash by setting __hash__=None at
1316 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1317 level.
1318
Nick Coghlanb028f502008-07-13 14:52:36 +00001319- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1320 the parent module cannot be found while performing an absolute import.
1321 This means that an incorrectly defined __package__ attribute will
1322 now only prevent relative imports in that module rather than causing
1323 all imports from that module to fail.
1324
Nick Coghlan14ff9942008-07-08 14:21:42 +00001325- Issue #2517: Allow unicode messages in Exceptions again by correctly
1326 bypassing the instance dictionary when looking up __unicode__ on
1327 new-style classes.
1328
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001329- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1330 set to a custom object whose write() method happens to install
1331 another file in sys.stdout.
1332
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001333- Issue #3088: Corrected a race condition in classes derived from
1334 threading.local: the first member set by a thread could be saved in
1335 another thread's dictionary.
1336
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001337- Issue #3004: Minor change to slice.indices(): the start and stop
1338 arguments are now treated identically, making the behaviour easier
1339 to describe and understand. For example, slice(None, -10,
1340 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1341 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1342 10, -1).
1343
Georg Brandl278fc502008-07-19 12:46:12 +00001344- Issue #3219: Calling a function with repeated keyword arguments,
1345 f(a=2, a=23), would not cause a syntax error. This was a regression
1346 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001347
Georg Brandl278fc502008-07-19 12:46:12 +00001348- Issue #2862: Make int and float freelist management consistent with
1349 other freelists. Changes their CompactFreeList apis into
1350 ClearFreeList apis and calls them via gc.collect().

1356 api functions without holding the GIL, which could lead to a fatal
1357 error when they failed.
1358
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001359- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1368 ForkingPickler.register() to resolve conflict with ctypes.
1369
Vinay Sajip51e65192008-07-18 09:01:10 +00001370- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001371

1381
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001382- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001383
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001384- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1385 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001386 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001387 content-length. The problem had been corrected in the 2.4 branch, but never
1388 merged into trunk.
1389
Georg Brandle78fbcc2008-07-05 10:13:36 +00001390- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001403- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1404 handling is now the same as that of other special attributes like __name__).
1405
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001406- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

1860 using the 'warning's machinery in such places as the parser where
1861 use of pure Python code is not possible. Both the ``showarning()``
1862 and ``formatwarning()`` gain an optional 'line' argument which is
1863 not called by default for backwards-compatibility reasons. Setting
1864 ``warnings.showwarning()`` to an implementation that lacks support
1865 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001928- Issue #2550: The approach used by client/server code for obtaining
1929 ports to listen on in network-oriented tests has been refined in an
1930 effort to facilitate running multiple instances of the entire
1931 regression test suite in parallel without issue.
1932 test_support.bind_port() has been fixed such that it will always
1933 return a unique port -- which wasn't always the case with the
1934 previous implementation, especially if socket options had been set
1935 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1936 new implementation of bind_port() will actually raise an exception
1937 if it is passed an AF_INET/SOCK_STREAM socket with either the
1938 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1939 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1940 the socket it's been passed. This currently only applies to
1941 Windows. This option prevents any other sockets from binding to the
1942 host/port we've bound to, thus removing the possibility of the
1943 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1944 when a second SOCK_STREAM socket binds and accepts to a host/port
1945 that's already been bound by another socket. The optional preferred
1946 port parameter to bind_port() has been removed. Under no
1947 circumstances should tests be hard coding ports!
1948
1949 test_support.find_unused_port() has also been introduced, which will
1950 pass a temporary socket object to bind_port() in order to obtain an
1951 unused port. The temporary socket object is then closed and
1952 deleted, and the port is returned. This method should only be used
1953 for obtaining an unused port in order to pass to an external program
1954 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1955 a parameter to a server-oriented class that doesn't give you direct
1956 access to the underlying socket used.
1957
1958 Finally, test_support.HOST has been introduced, which should be used
1959 for the host argument of any relevant socket calls (i.e. bind and
1960 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001961
1962 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001963 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001964 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1965 test_asynchat and test_socket_ssl.
1966
Georg Brandl3ee81df2008-05-17 18:14:43 +00001967 It is now possible for multiple instances of the regression test
1968 suite to run in parallel without issue.

2235-----------------
2236
Fred Drakea8ee94b2008-03-01 02:45:07 +00002237- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002238 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002239
Georg Brandlad61bc82008-02-23 15:11:18 +00002240- Issue #2067: file.__exit__() now calls subclasses' close() method.
2241
2242- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002243
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002244- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002245 issue 215555 for a discussion.
2246
Eric Smitha73fbe72008-02-23 03:09:44 +00002247- Added the future_builtins module, which contains hex() and oct().
2248 These are the PEP 3127 version of these functions, designed to be
2249 compatible with the hex() and oct() builtins from Python 3.0. They
2250 differ slightly in their output formats from the existing, unchanged
2251 Python 2.6 builtins. The expected usage of the future_builtins
2252 module is:
2253 from future_builtins import hex, oct
2254
Eric Smith7ef40bf2008-02-20 23:34:22 +00002255- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2256 exponents for exponents with absolute value < 100. Follows C99
2257 standard. This is a change on Windows, which would use 3 digits.
2258 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2259 so that any alterations it does to the resulting string will be
2260 available in stringlib/formatter.h (for float.__format__).
2261
Eric Smith5a3c1352008-02-19 13:21:56 +00002262- Implemented PEP 3101, Advanced String Formatting. This adds a new
2263 builtin format(); a format() method for str and unicode; a
2264 __format__() method to object, str, unicode, int, long, float, and
2265 datetime; the class string.Formatter; and the C API
2266 PyObject_Format().
2267
Georg Brandl3ee81df2008-05-17 18:14:43 +00002268- Fixed several potential crashes, all caused by specially crafted
2269 __del__ methods exploiting objects in temporarily inconsistent
2270 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002271
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002272- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002273 prevent a possible crash: an Abstract Base Class would try to access
2274 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002275

Georg Brandl3ee81df2008-05-17 18:14:43 +00002279- Clear all free lists during a gc.collect() of the highest generation
2280 in order to allow pymalloc to free more arenas. Python may give back
2281 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002282
Georg Brandl3ee81df2008-05-17 18:14:43 +00002283- Issue #2045: Fix an infinite recursion triggered when printing a
2284 subclass of collections.defaultdict, if its default_factory is set
2285 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002286
Christian Heimesf75dbef2008-02-08 00:11:31 +00002287- Fixed a minor memory leak in dictobject.c. The content of the free
2288 list was not freed on interpreter shutdown.
2289
Georg Brandl3ee81df2008-05-17 18:14:43 +00002290- Limit free list of method and builtin function objects to 256
2291 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002292
Georg Brandl3ee81df2008-05-17 18:14:43 +00002293- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2294 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002295 to compact the internal free lists of pre-allocted ints and floats.
2296
Georg Brandl3ee81df2008-05-17 18:14:43 +00002297- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2298 calls. Python expected the return type int but the fork familie
2299 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002300
Georg Brandl3ee81df2008-05-17 18:14:43 +00002301- Issue #1678380: Fix a bug that identifies 0j and -0j when they

2311 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002312
Georg Brandl3ee81df2008-05-17 18:14:43 +00002313- Patch #1473257: generator objects gain a gi_code attribute. This is
2314 the same object as the func_code attribute of the function that
2315 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002316
Georg Brandl3ee81df2008-05-17 18:14:43 +00002317- Issue #1920: "while 0" statements were completely removed by the
2318 compiler, even in the presence of an "else" clause, which is
2319 supposed to be run when the condition is false. Now the compiler
2320 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002321
Guido van Rossumeead05f2008-01-24 18:21:02 +00002322- A few crashers fixed: weakref_in_del.py (issue #1377858);
2323 loosing_dict_ref.py (issue #1303614, test67.py);
2324 borrowed_ref_[34].py (not in tracker).
2325
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002326- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002327 suppressed while an extension is loaded by calling SetErrorMode in

2329
Georg Brandl3ee81df2008-05-17 18:14:43 +00002330- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002331 several extension methods and modules do not work without unicode
2332 support.
2333
Georg Brandl26543b12008-01-21 18:36:51 +00002334- Issue #1882: when compiling code from a string, encoding cookies in the
2335 second line of code were not always recognized correctly.
2336
Georg Brandl14404b62008-01-19 19:27:05 +00002337- Issue #1679: "0x" was taken as a valid integer literal.
2338
Georg Brandl6caad7d2008-01-26 14:19:22 +00002339- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002340 added.
2341
Christian Heimesc94e2b52008-01-14 04:13:37 +00002342- sys.float_info / PyFloat_GetInfo: The floating point information
2343 object was converted from a dict to a specialized structseq object.
2344
Georg Brandl3ee81df2008-05-17 18:14:43 +00002345- Patch #1816: Added sys.flags structseq. It exposes the status of
2346 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002347
Georg Brandl3ee81df2008-05-17 18:14:43 +00002348- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00002352- Patch #1700288: added a type attribute cache that caches method
2353 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002354
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002355- Bug #1776: __import__() no longer accepts filenames on any platform.

2361 envvar and sys.dont_write_bytecode attribute. All these can be set
2362 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002364- Improve some exception messages when Windows fails to load an
2365 extension module. Now we get for example '%1 is not a valid Win32
2366 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00002373- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002374 and INF. float("nan"), float("inf") and float("-inf") now work on
2375 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002377- Compiler now generates simpler and faster code for dictionary
2378 literals. The oparg for BUILD_MAP now indicates an estimated
2379 dictionary size. There is a new opcode, STORE_MAP, for adding
2380 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002409- Patch #1739468: Directories and zipfiles containing a __main__.py
2410 file can now be directly executed by passing their name to the
2411 interpreter. The directory/zipfile is automatically inserted as the
2412 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002414- Issue #1265: Fix a problem with sys.settrace, if the tracing
2415 function uses a generator expression when at the same time the
2416 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002417
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002418- sets and frozensets now have an isdisjoint() method.

2423
Georg Brandl3ee81df2008-05-17 18:14:43 +00002424- The enumerate() builtin function is no longer bounded to sequences
2425 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2426 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002427
Georg Brandl3ee81df2008-05-17 18:14:43 +00002428- Issue #1686386: Tuple's tp_repr did not take into account the
2429 possibility of having a self-referential tuple, which is possible
2430 from C code. Nor did object's tp_str consider that a type's tp_str
2431 could do something that could lead to an inifinite recursion.
2432 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2433 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002434
Georg Brandl3ee81df2008-05-17 18:14:43 +00002435- Issue #1164: It was possible to trigger deadlock when using the
2436 'print' statement to write to a file since the GIL was not released
2437 as needed. Now PyObject_Print() does the right thing along with
2438 various tp_print implementations of the built-in types and those in
2439 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002440
Georg Brandl3ee81df2008-05-17 18:14:43 +00002441- Issue #1147: Exceptions were directly allowing string exceptions in
2442 their throw() method even though string exceptions no longer
2443 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002444
Georg Brandl3ee81df2008-05-17 18:14:43 +00002445- Issue #1096: Prevent a segfault from getting the repr of a very
2446 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002447
Brett Cannon1e534b52007-09-07 04:18:30 +00002448- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002449 PyObject_Call() never calling back out to Python code to trigger
2450 recursion depth updates/checks. Required the creation of a static
2451 RuntimeError instance in case normalizing an exception put the
2452 recursion check value past its limit. Fixes crashers
2453 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002454

Neal Norwitz0ac60192007-05-27 04:08:54 +00002468- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002469 __*__ attributes. (Some already existed, e.g., __doc__ and
2470 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002471
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002472- Add -3 option to the interpreter to warn about features that are
2473 deprecated and will be changed/removed in Python 3.0.
2474
Georg Brandl2134e752007-05-21 20:34:16 +00002475- Patch #1686487: you can now pass any mapping after '**' in function
2476 calls.
2477
Collin Winter62903052007-05-18 23:11:24 +00002478- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002479 "except E as target:". This is to provide forwards compatibility
2480 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002481
Brett Cannon229cee22007-05-05 01:34:02 +00002482- Deprecate BaseException.message as per PEP 352.
2483
Georg Brandl3ee81df2008-05-17 18:14:43 +00002484- Issue #1303614: don't expose object's __dict__ when the dict is

2486
Vinay Sajip8549ce32007-05-06 17:53:37 +00002487- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002488 setting a plain string, ie don't expand to single letter identifiers.
2489
Raymond Hettinger13936692007-04-11 18:40:58 +00002490- Request #1191699: Slices can now be pickled.
2491
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002492- Request #1193128: str.translate() now allows a None argument for
2493 translations that only remove characters without re-mapping the
2494 remaining characters.
2495
Georg Brandl5cb76c12007-03-21 09:00:39 +00002496- Patch #1682205: a TypeError while unpacking an iterable is no longer
2497 masked by a generic one with the message "unpack non-sequence".
2498
Neal Norwitzaa754b72007-03-21 06:39:48 +00002499- Remove unused file Python/fmod.c.
2500
Guido van Rossum143b5642007-03-23 04:58:42 +00002501- Bug #1683368: The object.__init__() and object.__new__() methods are
2502 now stricter in rejecting excess arguments. The only time when
2503 either allows excess arguments is when it is not overridden and the
2504 other one is. For backwards compatibility, when both are
2505 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002506 warning later). Also, type.__init__() insists on the same signature
2507 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002508
Georg Brandl3ee81df2008-05-17 18:14:43 +00002509- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2510 object to complex using its __complex__() method before falling back
2511 to the __float__() method. Therefore, the functions in the cmath
2512 module now can operate on objects that define a __complex__()
2513 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002514
Georg Brandl3ee81df2008-05-17 18:14:43 +00002515- Patch #1623563: allow __class__ assignment for classes with
2516 __slots__. The old and the new class are still required to have the
2517 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002518

2523 ``object.__reduce_ex__()`` is called with an object that is faking
2524 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002525
Georg Brandl3ee81df2008-05-17 18:14:43 +00002526- Patch #1680015: Don't modify __slots__ tuple if it contains an

2530
Georg Brandl7b9c5552007-03-12 14:30:05 +00002531- Bug #1678647: write a newline after printing an exception in any
2532 case, even when converting the value to a string failed.
2533
Georg Brandl871f1bc2007-03-12 13:17:36 +00002534- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002535 its argument, if it exists. If not, it will work like before. This
2536 allows customizing the output of dir() in the presence of a
2537 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002538
Collin Winter276887b2007-03-12 16:11:39 +00002539- Patch #922167: Python no longer segfaults when faced with infinitely
2540 self-recursive reload() calls (as reported by bug #742342).
2541
Georg Brandl3ee81df2008-05-17 18:14:43 +00002542- Patch #1675981: remove unreachable code from ``type.__new__()``

2546 parthensized forms. This means complex(repr(x)) now works instead of
2547 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002548
Georg Brandlaa2321b2007-03-07 00:40:28 +00002549- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002550 makes the filenames the warning module prints much more sensible
2551 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002552

2554 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002555 variable is given, but break into the interactive interpreter just
2556 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002564- Patch #1674228: when assigning a slice (old-style), check for the
2565 sq_ass_slice instead of the sq_slice slot.
2566
Georg Brandl3ee81df2008-05-17 18:14:43 +00002567- When printing an unraisable error, don't print exceptions. before
2568 the name. This duplicates the behavior whening normally printing
2569 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003102 AttributeError instead of an IOError when the server's response
3103 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003104

Georg Brandl3ee81df2008-05-17 18:14:43 +00003109- Patch #1429539: pdb now correctly initializes the __main__ module
3110 for the debugged script, which means that imports from __main__ work

3119
Georg Brandl3ee81df2008-05-17 18:14:43 +00003120- Patch #1530482: add pydoc.render_doc() which returns the

3135
Georg Brandl92a6bae2007-03-13 17:43:32 +00003136- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003137 are set for invalid interpolation sequences that would lead to
3138 errors on reading back those values.

3181 returned string up to the first NUL character.

3192
Georg Brandl3ee81df2008-05-17 18:14:43 +00003193- unittest now verifies more of its assumptions. In particular,
3194 TestCase and TestSuite subclasses (not instances) are no longer
3195 accepted in TestSuite.addTest(). This should cause no
3196 incompatibility since it never made sense with ordinary subclasses
3197 -- the failure just occurred later, with a more cumbersome
3198 exception.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003586- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00003587 time so that opening a database previously created with the DB_DUP
3588 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3589 opens. Specifically: dictionary assignment to a DB object will
3590 replace all values for a given key when the database allows
3591 duplicate values. DB users should use DB.put(k, v) when they want
3592 to store duplicates; not DB[k] = v.

3599 characters with ASCII value less than 32. Also, it correctly quotes
3600 dots only if they occur on a single line, as opposed to the previous
3601 behavior of quoting dots if they are the second character of any
3602 line.

3948 of w# format code incorrectly truncated the length to an int, even
3949 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3950 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003980- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3981 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
