749What's New in Python 2.6.1
750==========================
751
752*Release date: 04-Dec-2008*
753
754Core and Builtins
755-----------------
756
757- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
758 interpreter to abort ("Fatal Python error: Could not reset the stack!")
759 instead of throwing a MemoryError.
760
761- Issue #4367: Python would segfault during compiling when the unicodedata
762 module couldn't be imported and \N escapes were present.
763
764- Issue #4348: Some bytearray methods returned that didn't cause any change to
765 the bytearray, returned the same bytearray instead of a copy.
766
767- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
768
769- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
770
771- Issue #4048: The parser module now correctly validates relative imports.
772
773- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

780 __future__ import didn't work.
781
782- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
783 returned a path longer than MAX_PATH. (But It's doubtful this code path is
784 really executed because I cannot move to such directory on win2k)
785
786- Issue #4069: When set.remove(element) is used with a set element, the element
787 is temporarily replaced with an equivalent frozenset. But the eventual
788 KeyError would always report the empty frozenset([]) as the missing key. Now
789 it correctly refers to the initial element.
790
791- Fixed C99 style comments in several files. Python is now C89 compatible
792 again.

940
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000941- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
942 PyString_FromFormat or PyErr_Format to display size_t values. The macro
943 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
944 ``printf`` function, whereas PyString_FromFormat has an independent

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

Antoine Pitrou0668c622008-08-26 22:42:08 +0000967 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
968 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1040
Brett Cannon1eaf0742008-09-02 01:25:16 +00001041- Issue 3602: Moved test.test_support.catch_warning() to
1042 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1043 for catch_warnings() also led to an improvement in the raising of a
1044 DeprecationWarning related to warnings.warn_explicit().
1045
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001046- The deprecation warnings for the old camelCase threading API were removed.

1064-----------------
1065
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001066- Issue #2975: When compiling several extension modules with Visual Studio 2008
1067 from the same python interpreter, some environment variables would grow
1068 without limit.
1069
Benjamin Peterson37346b22008-08-23 20:27:43 +00001070- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

1086 wrapper for warnings.catch_warnings() that makes it easier to check
1087 that expected warning messages are being reported.
1088

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001107What's New in Python 2.6 beta 3?
1108================================
1109
Barry Warsaw07a4a382008-08-21 01:15:08 +00001110*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001111
1112Core and Builtins
1113-----------------
1114
Guido van Rossumf8402962008-08-20 15:01:50 +00001115- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1116 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1117 extensions do not automatically benefit from the class attribute
1118 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1119 to their tp_flags field if they care. This is a backwards
1120 compatibility feature; in 3.0, all types will use the cache by
1121 default.
1122
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001123- Keyword arguments can now follow starred arguments. (``f(a, *args,
1124 keyword=23)`` is now valid syntax.)
1125
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001126- ctypes function pointers that are COM methods have a boolean True
1127 value again.
1128
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001129- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1130 by denying s# to parse objects that have a releasebuffer procedure,
1131 and introducing s*.
1132
Georg Brandl1e13ea92008-08-11 09:07:59 +00001133- Issue #3537: Fix an assertion failure when an empty but presized dict
1134 object was stored in the freelist.
1135
Mark Dickinsonb6467572008-08-04 21:30:09 +00001136- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1137 ValueError consistently across platforms.
1138
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001139- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1140 (64bit Unix, for example), unichr() would truncate its argument and return
1141 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1142
Neal Norwitze7d8be82008-07-31 17:17:14 +00001143- Apply security patches from Apple.
1144
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001145- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1146 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1147
Antoine Pitrou92f82162008-07-25 22:22:08 +00001148- Issue #1819: function calls with several named parameters are now on
1149 average 35% faster (as measured by pybench).
1150
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001151- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1152 the python debugger steps into a class statement: the free variables (local
1153 variables defined in an outer scope) would be deleted from the outer scope.
1154
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001155- Issue #2620: Overflow checking when allocating or reallocating memory
1156 was not always being done properly in some python types and extension
1157 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1158 all been updated to perform better checks and places in the code that
1159 would previously leak memory on the error path when such an allocation
1160 failed have been fixed.
1161

1163-------
1164
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001165- Issue #3612: Added some missing basic types in ctypes.wintypes.
1166
Benjamin Petersone977ad42008-08-20 01:42:01 +00001167- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1168 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1169
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001170- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1171 version reported by these tools does not necessarily follow the python
1172 version numbering scheme, so the module is less strict when parsing it.
1173
Nick Coghlanf70385a2008-08-18 12:42:46 +00001174- Issue #2235: Added Py3k warnings for types which will become unhashable
1175 under the stricter __hash__ inheritance rules in 3.0. Several types
1176 which did not meet the rules for hash invariants and were already
1177 unhashable in 3.0 have now been explicitly flagged as unhashable in
1178 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1179 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1180
Brett Cannon88f801d2008-08-18 00:46:22 +00001181- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1189
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001190- Issue #3575: Incremental decoder's decode function now takes bytearray
1191 by using 's*' instead of 't#'.
1192
Jesus Cea585ad8a2009-07-02 15:37:21 +00001193- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001194 fails unicode conversion on 2nd parameter. (windows only)
1195
Facundo Batista94f243a2008-08-17 03:38:39 +00001196- Issue 2464. urllib2 now supports a malformation in the URL received
1197 in a redirect.
1198
Brett Cannonabe423e2008-08-16 21:47:07 +00001199- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001200 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001201
Facundo Batistaeb90b782008-08-16 14:44:07 +00001202- Issue #2776: fixed small issue when handling an URL with double slash
1203 after a 302 response in the case of not going through a proxy.
1204
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001205- Issue #2676: in the email package, content-type parsing was hanging on
1206 pathological input because of quadratic or exponential behaviour of a
1207 regular expression.
1208
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001209- Issue #3476: binary buffered reading through the new "io" library is now
1210 thread-safe.
1211
Brett Cannonbf3157b2008-08-14 05:00:03 +00001212- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1213 since mimetools itself is deprecated. Because modules are cached, all
1214 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1215
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001216- Issue #3134: shutil referenced undefined WindowsError symbol.
1217
Robert Schuppenies14646332008-08-10 11:01:53 +00001218- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1219 menu entries were not deleted.
1220
Brett Cannon83e81842008-08-09 23:30:55 +00001221- Copied the implementation of reduce() to _functools.reduce() to have a
1222 version that did not raise a DeprecationWarning under -3.
1223
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001224- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1225 a MemoryError rather than silently stop the iteration.
1226
Guido van Rossum59ce9012008-08-09 14:55:34 +00001227- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1228 to _sre.compile() will now be rejected. This should not affect anybody
1229 since the re.compile() function never generates invalid re-bytecode.
1230
Skip Montanaroa032bf42008-08-08 22:52:51 +00001231- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Brett Cannon3aa2a492008-08-06 22:28:09 +00001235- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1236 the reload() built-in has been removed.

Antoine Pitroude781a42008-08-09 12:43:23 +00001250 asking for a specific length. This problem only affected files opened
1251 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001252

1277 file name rather than a ZipInfo instance, so files are extracted with
1278 mode 0600 rather than 000 under Unix.
1279
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001280- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1281 argument in python 2.5, this broke code that subclassed Popen to include its

1296 coverage of the lookup process for special methods. The disclaimers
1297 regarding lack of coverage of new-style classes have also been

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001301What's New in Python 2.6 beta 2?
1302================================
1303
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001304*Release date: 17-Jul-2008*
1305
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001306Core and Builtins
1307-----------------
1308
Georg Brandl3e483f62008-07-16 22:57:41 +00001309- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1310 its methods now allow for items objects that can be converted to
1311 an integer using operator.index().
1312
Mark Dickinson64b7e502008-07-16 09:40:03 +00001313- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1314 produced a ValueError instead of giving the correct float.
1315
Eric Smitha5fa5a22008-07-16 00:11:49 +00001316- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1317 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1318
Mark Dickinson7103aa42008-07-15 19:08:33 +00001319- Issue #3008: the float type has a new instance method 'float.hex'
1320 and a new class method 'float.fromhex' to convert floating-point
1321 numbers to and from hexadecimal strings, respectively.
1322
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001323- Issue #2235: __hash__ is once again inherited by default. To allow
1324 collections.Hashable to remain meaningful in the presence of the
1325 default hash implementation (object.__hash__), it is now possible
1326 to explicit block inheritance of hash by setting __hash__=None at
1327 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1328 level.
1329
Nick Coghlanb028f502008-07-13 14:52:36 +00001330- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1331 the parent module cannot be found while performing an absolute import.
1332 This means that an incorrectly defined __package__ attribute will
1333 now only prevent relative imports in that module rather than causing
1334 all imports from that module to fail.
1335
Nick Coghlan14ff9942008-07-08 14:21:42 +00001336- Issue #2517: Allow unicode messages in Exceptions again by correctly
1337 bypassing the instance dictionary when looking up __unicode__ on
1338 new-style classes.
1339
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001340- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1341 set to a custom object whose write() method happens to install
1342 another file in sys.stdout.
1343
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001344- Issue #3088: Corrected a race condition in classes derived from
1345 threading.local: the first member set by a thread could be saved in
1346 another thread's dictionary.
1347
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001348- Issue #3004: Minor change to slice.indices(): the start and stop
1349 arguments are now treated identically, making the behaviour easier
1350 to describe and understand. For example, slice(None, -10,
1351 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1352 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1353 10, -1).
1354
Georg Brandl278fc502008-07-19 12:46:12 +00001355- Issue #3219: Calling a function with repeated keyword arguments,
1356 f(a=2, a=23), would not cause a syntax error. This was a regression
1357 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001358
Georg Brandl278fc502008-07-19 12:46:12 +00001359- Issue #2862: Make int and float freelist management consistent with
1360 other freelists. Changes their CompactFreeList apis into
1361 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001362
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001363Library
1364-------
1365
Thomas Heller57adf222008-08-14 19:10:48 +00001366- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1367 api functions without holding the GIL, which could lead to a fatal
1368 error when they failed.
1369
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001370- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
1371

1377
Jesse Noller13e9d582008-07-16 14:32:36 +00001378- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1379 ForkingPickler.register() to resolve conflict with ctypes.
1380
Vinay Sajip51e65192008-07-18 09:01:10 +00001381- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001382
Thomas Heller880f5292008-07-15 19:39:38 +00001383- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1384 a valid dlerror() message.
1385
Thomas Heller2bad6572008-07-15 17:19:50 +00001386- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1387 incomplete structure was created.
1388
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001389- Issue #3339: dummy_thread.acquire() should not return None.
1390
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001391- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1392
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001393- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001394
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001395- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1396 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001397 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001398 content-length. The problem had been corrected in the 2.4 branch, but never
1399 merged into trunk.
1400
Georg Brandle78fbcc2008-07-05 10:13:36 +00001401- Issue #2663: add filtering capability to shutil.copytree().
1402

1404
1405- Issue #1526: Allow more than 64k files to be added to Zip64 file.
1406
1407- Issue #1746: Correct handling of zipfile archive comments (previously
1408 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00001409 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00001410
Vinay Sajip51e65192008-07-18 09:01:10 +00001411- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001412 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00001413
Nick Coghlanc060b0e2008-07-02 13:09:19 +00001414- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1415 handling is now the same as that of other special attributes like __name__).
1416
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001417- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
1418 removal in Python 3.0 in favor of urllib2.urlopen().

1426
Gregory P. Smithc4691ec2008-07-07 05:09:12 +00001427- Issue #3094: httplib.HTTPSConnection Host: headers no longer include the
1428 redundant ":443" port number designation when the connection is using the

1430
Gregory P. Smithdb3409c2008-07-17 03:13:05 +00001431- Issue #874900: after an os.fork() call the threading module state is cleaned

Georg Brandl3ee81df2008-05-17 18:14:43 +00001869- Issue #1631171: Re-implement the 'warnings' module in C (the
1870 original Python code has been kept as backup). This will allow for
1871 using the 'warning's machinery in such places as the parser where
1872 use of pure Python code is not possible. Both the ``showarning()``
1873 and ``formatwarning()`` gain an optional 'line' argument which is
1874 not called by default for backwards-compatibility reasons. Setting
1875 ``warnings.showwarning()`` to an implementation that lacks support
1876 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001939- Issue #2550: The approach used by client/server code for obtaining
1940 ports to listen on in network-oriented tests has been refined in an
1941 effort to facilitate running multiple instances of the entire
1942 regression test suite in parallel without issue.
1943 test_support.bind_port() has been fixed such that it will always
1944 return a unique port -- which wasn't always the case with the
1945 previous implementation, especially if socket options had been set
1946 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1947 new implementation of bind_port() will actually raise an exception
1948 if it is passed an AF_INET/SOCK_STREAM socket with either the
1949 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1950 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1951 the socket it's been passed. This currently only applies to
1952 Windows. This option prevents any other sockets from binding to the
1953 host/port we've bound to, thus removing the possibility of the
1954 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1955 when a second SOCK_STREAM socket binds and accepts to a host/port
1956 that's already been bound by another socket. The optional preferred
1957 port parameter to bind_port() has been removed. Under no
1958 circumstances should tests be hard coding ports!
1959
1960 test_support.find_unused_port() has also been introduced, which will
1961 pass a temporary socket object to bind_port() in order to obtain an
1962 unused port. The temporary socket object is then closed and
1963 deleted, and the port is returned. This method should only be used
1964 for obtaining an unused port in order to pass to an external program
1965 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1966 a parameter to a server-oriented class that doesn't give you direct
1967 access to the underlying socket used.
1968
1969 Finally, test_support.HOST has been introduced, which should be used
1970 for the host argument of any relevant socket calls (i.e. bind and
1971 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001972
1973 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001974 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001975 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1976 test_asynchat and test_socket_ssl.
1977
Georg Brandl3ee81df2008-05-17 18:14:43 +00001978 It is now possible for multiple instances of the regression test
1979 suite to run in parallel without issue.

2135 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00002136 platform.machine() and platform.processor() will report this
2137 information as well.

2246-----------------
2247
Fred Drakea8ee94b2008-03-01 02:45:07 +00002248- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002249 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002251- Issue #2067: file.__exit__() now calls subclasses' close() method.
2252
2253- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002254
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002255- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002256 issue 215555 for a discussion.
2257
Eric Smitha73fbe72008-02-23 03:09:44 +00002258- Added the future_builtins module, which contains hex() and oct().
2259 These are the PEP 3127 version of these functions, designed to be
2260 compatible with the hex() and oct() builtins from Python 3.0. They
2261 differ slightly in their output formats from the existing, unchanged
2262 Python 2.6 builtins. The expected usage of the future_builtins
2263 module is:
2264 from future_builtins import hex, oct
2265
Eric Smith7ef40bf2008-02-20 23:34:22 +00002266- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2267 exponents for exponents with absolute value < 100. Follows C99
2268 standard. This is a change on Windows, which would use 3 digits.
2269 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2270 so that any alterations it does to the resulting string will be
2271 available in stringlib/formatter.h (for float.__format__).
2272
Eric Smith5a3c1352008-02-19 13:21:56 +00002273- Implemented PEP 3101, Advanced String Formatting. This adds a new
2274 builtin format(); a format() method for str and unicode; a
2275 __format__() method to object, str, unicode, int, long, float, and
2276 datetime; the class string.Formatter; and the C API
2277 PyObject_Format().
2278
Georg Brandl3ee81df2008-05-17 18:14:43 +00002279- Fixed several potential crashes, all caused by specially crafted
2280 __del__ methods exploiting objects in temporarily inconsistent
2281 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002282
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002283- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002284 prevent a possible crash: an Abstract Base Class would try to access
2285 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002286

Georg Brandl3ee81df2008-05-17 18:14:43 +00002290- Clear all free lists during a gc.collect() of the highest generation
2291 in order to allow pymalloc to free more arenas. Python may give back
2292 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002293
Georg Brandl3ee81df2008-05-17 18:14:43 +00002294- Issue #2045: Fix an infinite recursion triggered when printing a
2295 subclass of collections.defaultdict, if its default_factory is set
2296 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002297
Christian Heimesf75dbef2008-02-08 00:11:31 +00002298- Fixed a minor memory leak in dictobject.c. The content of the free
2299 list was not freed on interpreter shutdown.
2300
Georg Brandl3ee81df2008-05-17 18:14:43 +00002301- Limit free list of method and builtin function objects to 256
2302 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002303
Georg Brandl3ee81df2008-05-17 18:14:43 +00002304- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2305 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002306 to compact the internal free lists of pre-allocted ints and floats.
2307
Georg Brandl3ee81df2008-05-17 18:14:43 +00002308- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2309 calls. Python expected the return type int but the fork familie
2310 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002311
Georg Brandl3ee81df2008-05-17 18:14:43 +00002312- Issue #1678380: Fix a bug that identifies 0j and -0j when they

2322 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002323
Georg Brandl3ee81df2008-05-17 18:14:43 +00002324- Patch #1473257: generator objects gain a gi_code attribute. This is
2325 the same object as the func_code attribute of the function that
2326 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002327
Georg Brandl3ee81df2008-05-17 18:14:43 +00002328- Issue #1920: "while 0" statements were completely removed by the
2329 compiler, even in the presence of an "else" clause, which is
2330 supposed to be run when the condition is false. Now the compiler
2331 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002332
Guido van Rossumeead05f2008-01-24 18:21:02 +00002333- A few crashers fixed: weakref_in_del.py (issue #1377858);

2335 borrowed_ref_[34].py (not in tracker).
2336
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002337- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002338 suppressed while an extension is loaded by calling SetErrorMode in

2340
Georg Brandl3ee81df2008-05-17 18:14:43 +00002341- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002342 several extension methods and modules do not work without unicode
2343 support.
2344
Georg Brandl26543b12008-01-21 18:36:51 +00002345- Issue #1882: when compiling code from a string, encoding cookies in the
2346 second line of code were not always recognized correctly.
2347
Georg Brandl14404b62008-01-19 19:27:05 +00002348- Issue #1679: "0x" was taken as a valid integer literal.
2349
Georg Brandl6caad7d2008-01-26 14:19:22 +00002350- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002351 added.
2352
Christian Heimesc94e2b52008-01-14 04:13:37 +00002353- sys.float_info / PyFloat_GetInfo: The floating point information
2354 object was converted from a dict to a specialized structseq object.
2355
Georg Brandl3ee81df2008-05-17 18:14:43 +00002356- Patch #1816: Added sys.flags structseq. It exposes the status of
2357 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002358
Georg Brandl3ee81df2008-05-17 18:14:43 +00002359- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00002375- Improve some exception messages when Windows fails to load an
2376 extension module. Now we get for example '%1 is not a valid Win32
2377 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002378

Christian Heimes0a8143f2007-12-18 23:22:54 +00002384- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002385 and INF. float("nan"), float("inf") and float("-inf") now work on
2386 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002387
Georg Brandl3ee81df2008-05-17 18:14:43 +00002388- Compiler now generates simpler and faster code for dictionary
2389 literals. The oparg for BUILD_MAP now indicates an estimated
2390 dictionary size. There is a new opcode, STORE_MAP, for adding
2391 entries to the dictionary.

2409 running, and if the deallocation of its frames somehow calls the
2410 PyGILState_Ensure() / PyGILState_Release() functions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002420- Patch #1739468: Directories and zipfiles containing a __main__.py
2421 file can now be directly executed by passing their name to the
2422 interpreter. The directory/zipfile is automatically inserted as the
2423 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002424
Georg Brandl3ee81df2008-05-17 18:14:43 +00002425- Issue #1265: Fix a problem with sys.settrace, if the tracing
2426 function uses a generator expression when at the same time the
2427 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002428
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002429- sets and frozensets now have an isdisjoint() method.

2434
Georg Brandl3ee81df2008-05-17 18:14:43 +00002435- The enumerate() builtin function is no longer bounded to sequences
2436 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2437 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002438
Georg Brandl3ee81df2008-05-17 18:14:43 +00002439- Issue #1686386: Tuple's tp_repr did not take into account the
2440 possibility of having a self-referential tuple, which is possible
2441 from C code. Nor did object's tp_str consider that a type's tp_str
2442 could do something that could lead to an inifinite recursion.
2443 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2444 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002445
Georg Brandl3ee81df2008-05-17 18:14:43 +00002446- Issue #1164: It was possible to trigger deadlock when using the
2447 'print' statement to write to a file since the GIL was not released
2448 as needed. Now PyObject_Print() does the right thing along with
2449 various tp_print implementations of the built-in types and those in
2450 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002451
Georg Brandl3ee81df2008-05-17 18:14:43 +00002452- Issue #1147: Exceptions were directly allowing string exceptions in
2453 their throw() method even though string exceptions no longer
2454 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002455
Georg Brandl3ee81df2008-05-17 18:14:43 +00002456- Issue #1096: Prevent a segfault from getting the repr of a very
2457 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002458
Brett Cannon1e534b52007-09-07 04:18:30 +00002459- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002460 PyObject_Call() never calling back out to Python code to trigger
2461 recursion depth updates/checks. Required the creation of a static
2462 RuntimeError instance in case normalizing an exception put the
2463 recursion check value past its limit. Fixes crashers
2464 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002465
Georg Brandl3ee81df2008-05-17 18:14:43 +00002466- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00002479- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002480 __*__ attributes. (Some already existed, e.g., __doc__ and
2481 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002482
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002483- Add -3 option to the interpreter to warn about features that are
2484 deprecated and will be changed/removed in Python 3.0.
2485
Georg Brandl2134e752007-05-21 20:34:16 +00002486- Patch #1686487: you can now pass any mapping after '**' in function
2487 calls.
2488
Collin Winter62903052007-05-18 23:11:24 +00002489- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002490 "except E as target:". This is to provide forwards compatibility
2491 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002492
Brett Cannon229cee22007-05-05 01:34:02 +00002493- Deprecate BaseException.message as per PEP 352.
2494
Georg Brandl3ee81df2008-05-17 18:14:43 +00002495- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002496 inherited from a builtin base.
2497
Vinay Sajip8549ce32007-05-06 17:53:37 +00002498- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002499 setting a plain string, ie don't expand to single letter identifiers.
2500
Raymond Hettinger13936692007-04-11 18:40:58 +00002501- Request #1191699: Slices can now be pickled.
2502
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002503- Request #1193128: str.translate() now allows a None argument for
2504 translations that only remove characters without re-mapping the
2505 remaining characters.
2506
Georg Brandl5cb76c12007-03-21 09:00:39 +00002507- Patch #1682205: a TypeError while unpacking an iterable is no longer
2508 masked by a generic one with the message "unpack non-sequence".
2509
Neal Norwitzaa754b72007-03-21 06:39:48 +00002510- Remove unused file Python/fmod.c.
2511
Guido van Rossum143b5642007-03-23 04:58:42 +00002512- Bug #1683368: The object.__init__() and object.__new__() methods are
2513 now stricter in rejecting excess arguments. The only time when
2514 either allows excess arguments is when it is not overridden and the
2515 other one is. For backwards compatibility, when both are
2516 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002517 warning later). Also, type.__init__() insists on the same signature
2518 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002519
Georg Brandl3ee81df2008-05-17 18:14:43 +00002520- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2521 object to complex using its __complex__() method before falling back
2522 to the __float__() method. Therefore, the functions in the cmath
2523 module now can operate on objects that define a __complex__()
2524 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002525
Georg Brandl3ee81df2008-05-17 18:14:43 +00002526- Patch #1623563: allow __class__ assignment for classes with
2527 __slots__. The old and the new class are still required to have the
2528 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002529
Georg Brandl3ee81df2008-05-17 18:14:43 +00002530- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002533- Patch #1462488: Python no longer segfaults when
2534 ``object.__reduce_ex__()`` is called with an object that is faking
2535 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002536
Georg Brandl3ee81df2008-05-17 18:14:43 +00002537- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002540- Patch #1444529: the builtin compile() now accepts keyword arguments.
2541
Georg Brandl7b9c5552007-03-12 14:30:05 +00002542- Bug #1678647: write a newline after printing an exception in any
2543 case, even when converting the value to a string failed.
2544
Georg Brandl871f1bc2007-03-12 13:17:36 +00002545- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002546 its argument, if it exists. If not, it will work like before. This
2547 allows customizing the output of dir() in the presence of a
2548 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002549
Collin Winter276887b2007-03-12 16:11:39 +00002550- Patch #922167: Python no longer segfaults when faced with infinitely
2551 self-recursive reload() calls (as reported by bug #742342).
2552
Georg Brandl3ee81df2008-05-17 18:14:43 +00002553- Patch #1675981: remove unreachable code from ``type.__new__()``
2554 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002556- Patch #1491866: change the complex() constructor to allow
2557 parthensized forms. This means complex(repr(x)) now works instead of
2558 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002559
Georg Brandlaa2321b2007-03-07 00:40:28 +00002560- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002561 makes the filenames the warning module prints much more sensible
2562 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002563
Georg Brandl49aafc92007-03-07 00:34:46 +00002564- Variant of patch #697613: don't exit the interpreter on a SystemExit
2565 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002566 variable is given, but break into the interactive interpreter just
2567 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002575- Patch #1674228: when assigning a slice (old-style), check for the
2576 sq_ass_slice instead of the sq_slice slot.
2577
Georg Brandl3ee81df2008-05-17 18:14:43 +00002578- When printing an unraisable error, don't print exceptions. before
2579 the name. This duplicates the behavior whening normally printing
2580 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003113 AttributeError instead of an IOError when the server's response
3114 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003115

Georg Brandl3ee81df2008-05-17 18:14:43 +00003131- Patch #1530482: add pydoc.render_doc() which returns the

3146
Georg Brandl92a6bae2007-03-13 17:43:32 +00003147- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003148 are set for invalid interpolation sequences that would lead to
3149 errors on reading back those values.

3203
Georg Brandl3ee81df2008-05-17 18:14:43 +00003204- unittest now verifies more of its assumptions. In particular,
3205 TestCase and TestSuite subclasses (not instances) are no longer
3206 accepted in TestSuite.addTest(). This should cause no
3207 incompatibility since it never made sense with ordinary subclasses
3208 -- the failure just occurred later, with a more cumbersome
3209 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003496 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00003598 time so that opening a database previously created with the DB_DUP
3599 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3600 opens. Specifically: dictionary assignment to a DB object will
3601 replace all values for a given key when the database allows
3602 duplicate values. DB users should use DB.put(k, v) when they want
3603 to store duplicates; not DB[k] = v.

Christian Heimes5b970ad2008-02-06 13:33:44 +00003942
Georg Brandl3ee81df2008-05-17 18:14:43 +00003943- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3944 to ``PyTuple_SetItem``, it can be used to populate a brand new

3957
Georg Brandl3ee81df2008-05-17 18:14:43 +00003958- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3959 of w# format code incorrectly truncated the length to an int, even
3960 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3961 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003962
Georg Brandl3ee81df2008-05-17 18:14:43 +00003963- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

3985 outside of pystate.c and should not be necessary.
3986
Georg Brandl3ee81df2008-05-17 18:14:43 +00003987- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3988 absolute imports. In earlier versions they might have used relative
3989 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003990
Georg Brandl3ee81df2008-05-17 18:14:43 +00003991- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3992 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003993
Georg Brandl3ee81df2008-05-17 18:14:43 +00003994- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004019- Removed the macfs module. It had been deprecated since Python 2.5.
4020 This lead to the deprecation of macostools.touched() as it relied
