747What's New in Python 2.6.1
748==========================
749
750*Release date: 04-Dec-2008*
751
752Core and Builtins
753-----------------
754
755- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
756 interpreter to abort ("Fatal Python error: Could not reset the stack!")
757 instead of throwing a MemoryError.
758
759- Issue #4367: Python would segfault during compiling when the unicodedata
760 module couldn't be imported and \N escapes were present.
761
762- Issue #4348: Some bytearray methods returned that didn't cause any change to
763 the bytearray, returned the same bytearray instead of a copy.
764
765- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
766
767- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
768
769- Issue #4048: The parser module now correctly validates relative imports.
770
771- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
772 exec statement.
773
774- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
775 method does not return iterators for the 4th and 5th items.
776
777- Issue #4209: Enabling unicode_literals and the print_function in the same
778 __future__ import didn't work.
779
780- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
781 returned a path longer than MAX_PATH. (But It's doubtful this code path is
782 really executed because I cannot move to such directory on win2k)
783
784- Issue #4069: When set.remove(element) is used with a set element, the element
785 is temporarily replaced with an equivalent frozenset. But the eventual
786 KeyError would always report the empty frozenset([]) as the missing key. Now
787 it correctly refers to the initial element.
788
789- Fixed C99 style comments in several files. Python is now C89 compatible
790 again.

938
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000939- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
940 PyString_FromFormat or PyErr_Format to display size_t values. The macro
941 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
942 ``printf`` function, whereas PyString_FromFormat has an independent

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

Antoine Pitrou0668c622008-08-26 22:42:08 +0000965 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
966 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1040 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1041 for catch_warnings() also led to an improvement in the raising of a
1042 DeprecationWarning related to warnings.warn_explicit().

1062-----------------
1063
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001064- Issue #2975: When compiling several extension modules with Visual Studio 2008
1065 from the same python interpreter, some environment variables would grow
1066 without limit.
1067
Benjamin Peterson37346b22008-08-23 20:27:43 +00001068- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001105What's New in Python 2.6 beta 3?
1106================================
1107
Barry Warsaw07a4a382008-08-21 01:15:08 +00001108*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001109
1110Core and Builtins
1111-----------------
1112
Guido van Rossumf8402962008-08-20 15:01:50 +00001113- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1114 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1115 extensions do not automatically benefit from the class attribute
1116 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1117 to their tp_flags field if they care. This is a backwards
1118 compatibility feature; in 3.0, all types will use the cache by
1119 default.
1120
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001121- Keyword arguments can now follow starred arguments. (``f(a, *args,
1122 keyword=23)`` is now valid syntax.)
1123
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001124- ctypes function pointers that are COM methods have a boolean True
1125 value again.
1126
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001127- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1128 by denying s# to parse objects that have a releasebuffer procedure,
1129 and introducing s*.
1130
Georg Brandl1e13ea92008-08-11 09:07:59 +00001131- Issue #3537: Fix an assertion failure when an empty but presized dict
1132 object was stored in the freelist.
1133
Mark Dickinsonb6467572008-08-04 21:30:09 +00001134- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1135 ValueError consistently across platforms.
1136
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001137- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1138 (64bit Unix, for example), unichr() would truncate its argument and return
1139 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1140
Neal Norwitze7d8be82008-07-31 17:17:14 +00001141- Apply security patches from Apple.
1142
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001143- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1144 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1145
Antoine Pitrou92f82162008-07-25 22:22:08 +00001146- Issue #1819: function calls with several named parameters are now on
1147 average 35% faster (as measured by pybench).
1148
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001149- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1150 the python debugger steps into a class statement: the free variables (local
1151 variables defined in an outer scope) would be deleted from the outer scope.
1152
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001153- Issue #2620: Overflow checking when allocating or reallocating memory
1154 was not always being done properly in some python types and extension
1155 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1156 all been updated to perform better checks and places in the code that
1157 would previously leak memory on the error path when such an allocation
1158 failed have been fixed.
1159

1161-------
1162
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001163- Issue #3612: Added some missing basic types in ctypes.wintypes.
1164
Benjamin Petersone977ad42008-08-20 01:42:01 +00001165- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1166 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1167
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001168- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1169 version reported by these tools does not necessarily follow the python
1170 version numbering scheme, so the module is less strict when parsing it.
1171
Nick Coghlanf70385a2008-08-18 12:42:46 +00001172- Issue #2235: Added Py3k warnings for types which will become unhashable
1173 under the stricter __hash__ inheritance rules in 3.0. Several types
1174 which did not meet the rules for hash invariants and were already
1175 unhashable in 3.0 have now been explicitly flagged as unhashable in
1176 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1177 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1178
Brett Cannon88f801d2008-08-18 00:46:22 +00001179- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1180 imported into the module but exposed as part of the module's API.
1181
Brett Cannon7b96f072008-08-18 00:41:11 +00001182- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1183
Brett Cannon46225e72008-08-18 00:36:52 +00001184- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001186- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1187
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001188- Issue #3575: Incremental decoder's decode function now takes bytearray
1189 by using 's*' instead of 't#'.
1190
Jesus Cea585ad8a2009-07-02 15:37:21 +00001191- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001192 fails unicode conversion on 2nd parameter. (windows only)
1193
Facundo Batista94f243a2008-08-17 03:38:39 +00001194- Issue 2464. urllib2 now supports a malformation in the URL received
1195 in a redirect.
1196
Brett Cannonabe423e2008-08-16 21:47:07 +00001197- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001198 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001199
Facundo Batistaeb90b782008-08-16 14:44:07 +00001200- Issue #2776: fixed small issue when handling an URL with double slash
1201 after a 302 response in the case of not going through a proxy.
1202
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001203- Issue #2676: in the email package, content-type parsing was hanging on
1204 pathological input because of quadratic or exponential behaviour of a
1205 regular expression.
1206
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001207- Issue #3476: binary buffered reading through the new "io" library is now
1208 thread-safe.
1209
Brett Cannonbf3157b2008-08-14 05:00:03 +00001210- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1211 since mimetools itself is deprecated. Because modules are cached, all
1212 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1213
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001214- Issue #3134: shutil referenced undefined WindowsError symbol.
1215
Robert Schuppenies14646332008-08-10 11:01:53 +00001216- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1217 menu entries were not deleted.
1218
Brett Cannon83e81842008-08-09 23:30:55 +00001219- Copied the implementation of reduce() to _functools.reduce() to have a
1220 version that did not raise a DeprecationWarning under -3.
1221
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001222- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1223 a MemoryError rather than silently stop the iteration.
1224
Guido van Rossum59ce9012008-08-09 14:55:34 +00001225- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1226 to _sre.compile() will now be rejected. This should not affect anybody
1227 since the re.compile() function never generates invalid re-bytecode.
1228
Skip Montanaroa032bf42008-08-08 22:52:51 +00001229- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Brett Cannon3aa2a492008-08-06 22:28:09 +00001233- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1234 the reload() built-in has been removed.
1235
Brett Cannon7e30b672008-08-04 21:52:25 +00001236- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001237 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001248 asking for a specific length. This problem only affected files opened
1249 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001250

1275 file name rather than a ZipInfo instance, so files are extracted with
1276 mode 0600 rather than 000 under Unix.
1277
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001278- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1279 argument in python 2.5, this broke code that subclassed Popen to include its

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001299What's New in Python 2.6 beta 2?
1300================================
1301
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001302*Release date: 17-Jul-2008*
1303
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001304Core and Builtins
1305-----------------
1306
Georg Brandl3e483f62008-07-16 22:57:41 +00001307- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1308 its methods now allow for items objects that can be converted to
1309 an integer using operator.index().
1310
Mark Dickinson64b7e502008-07-16 09:40:03 +00001311- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1312 produced a ValueError instead of giving the correct float.
1313
Eric Smitha5fa5a22008-07-16 00:11:49 +00001314- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1315 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1316
Mark Dickinson7103aa42008-07-15 19:08:33 +00001317- Issue #3008: the float type has a new instance method 'float.hex'
1318 and a new class method 'float.fromhex' to convert floating-point
1319 numbers to and from hexadecimal strings, respectively.
1320
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001321- Issue #2235: __hash__ is once again inherited by default. To allow
1322 collections.Hashable to remain meaningful in the presence of the
1323 default hash implementation (object.__hash__), it is now possible
1324 to explicit block inheritance of hash by setting __hash__=None at
1325 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1326 level.
1327
Nick Coghlanb028f502008-07-13 14:52:36 +00001328- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1329 the parent module cannot be found while performing an absolute import.
1330 This means that an incorrectly defined __package__ attribute will
1331 now only prevent relative imports in that module rather than causing
1332 all imports from that module to fail.
1333
Nick Coghlan14ff9942008-07-08 14:21:42 +00001334- Issue #2517: Allow unicode messages in Exceptions again by correctly
1335 bypassing the instance dictionary when looking up __unicode__ on
1336 new-style classes.
1337
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001338- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1339 set to a custom object whose write() method happens to install
1340 another file in sys.stdout.
1341
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001342- Issue #3088: Corrected a race condition in classes derived from
1343 threading.local: the first member set by a thread could be saved in
1344 another thread's dictionary.
1345
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001346- Issue #3004: Minor change to slice.indices(): the start and stop
1347 arguments are now treated identically, making the behaviour easier
1348 to describe and understand. For example, slice(None, -10,
1349 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1350 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1351 10, -1).
1352
Georg Brandl278fc502008-07-19 12:46:12 +00001353- Issue #3219: Calling a function with repeated keyword arguments,
1354 f(a=2, a=23), would not cause a syntax error. This was a regression
1355 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001356
Georg Brandl278fc502008-07-19 12:46:12 +00001357- Issue #2862: Make int and float freelist management consistent with
1358 other freelists. Changes their CompactFreeList apis into
1359 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001360
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001361Library
1362-------
1363
Thomas Heller57adf222008-08-14 19:10:48 +00001364- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1365 api functions without holding the GIL, which could lead to a fatal
1366 error when they failed.
1367
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001368- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
1369

1375
Jesse Noller13e9d582008-07-16 14:32:36 +00001376- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1377 ForkingPickler.register() to resolve conflict with ctypes.
1378
Vinay Sajip51e65192008-07-18 09:01:10 +00001379- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001380
Thomas Heller880f5292008-07-15 19:39:38 +00001381- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1382 a valid dlerror() message.
1383
Thomas Heller2bad6572008-07-15 17:19:50 +00001384- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1385 incomplete structure was created.
1386
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001387- Issue #3339: dummy_thread.acquire() should not return None.
1388
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001389- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1390
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001391- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001392
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001393- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1394 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001395 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001396 content-length. The problem had been corrected in the 2.4 branch, but never
1397 merged into trunk.
1398
Georg Brandle78fbcc2008-07-05 10:13:36 +00001399- Issue #2663: add filtering capability to shutil.copytree().

1402
1403- Issue #1526: Allow more than 64k files to be added to Zip64 file.
1404
1405- Issue #1746: Correct handling of zipfile archive comments (previously
1406 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00001407 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00001408
Vinay Sajip51e65192008-07-18 09:01:10 +00001409- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001410 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00001411
Nick Coghlanc060b0e2008-07-02 13:09:19 +00001412- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1413 handling is now the same as that of other special attributes like __name__).
1414
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001415- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
1416 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00001867- Issue #1631171: Re-implement the 'warnings' module in C (the
1868 original Python code has been kept as backup). This will allow for
1869 using the 'warning's machinery in such places as the parser where
1870 use of pure Python code is not possible. Both the ``showarning()``
1871 and ``formatwarning()`` gain an optional 'line' argument which is
1872 not called by default for backwards-compatibility reasons. Setting
1873 ``warnings.showwarning()`` to an implementation that lacks support
1874 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001937- Issue #2550: The approach used by client/server code for obtaining
1938 ports to listen on in network-oriented tests has been refined in an
1939 effort to facilitate running multiple instances of the entire
1940 regression test suite in parallel without issue.
1941 test_support.bind_port() has been fixed such that it will always
1942 return a unique port -- which wasn't always the case with the
1943 previous implementation, especially if socket options had been set
1944 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1945 new implementation of bind_port() will actually raise an exception
1946 if it is passed an AF_INET/SOCK_STREAM socket with either the
1947 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1948 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1949 the socket it's been passed. This currently only applies to
1950 Windows. This option prevents any other sockets from binding to the
1951 host/port we've bound to, thus removing the possibility of the
1952 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1953 when a second SOCK_STREAM socket binds and accepts to a host/port
1954 that's already been bound by another socket. The optional preferred
1955 port parameter to bind_port() has been removed. Under no
1956 circumstances should tests be hard coding ports!
1957
1958 test_support.find_unused_port() has also been introduced, which will
1959 pass a temporary socket object to bind_port() in order to obtain an
1960 unused port. The temporary socket object is then closed and
1961 deleted, and the port is returned. This method should only be used
1962 for obtaining an unused port in order to pass to an external program
1963 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1964 a parameter to a server-oriented class that doesn't give you direct
1965 access to the underlying socket used.
1966
1967 Finally, test_support.HOST has been introduced, which should be used
1968 for the host argument of any relevant socket calls (i.e. bind and
1969 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001970
1971 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001972 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001973 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1974 test_asynchat and test_socket_ssl.
1975
Georg Brandl3ee81df2008-05-17 18:14:43 +00001976 It is now possible for multiple instances of the regression test
1977 suite to run in parallel without issue.

2133 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00002134 platform.machine() and platform.processor() will report this
2135 information as well.

2244-----------------
2245
Fred Drakea8ee94b2008-03-01 02:45:07 +00002246- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002247 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002249- Issue #2067: file.__exit__() now calls subclasses' close() method.
2250
2251- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002252
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002253- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002254 issue 215555 for a discussion.
2255
Eric Smitha73fbe72008-02-23 03:09:44 +00002256- Added the future_builtins module, which contains hex() and oct().
2257 These are the PEP 3127 version of these functions, designed to be
2258 compatible with the hex() and oct() builtins from Python 3.0. They
2259 differ slightly in their output formats from the existing, unchanged
2260 Python 2.6 builtins. The expected usage of the future_builtins
2261 module is:
2262 from future_builtins import hex, oct
2263
Eric Smith7ef40bf2008-02-20 23:34:22 +00002264- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2265 exponents for exponents with absolute value < 100. Follows C99
2266 standard. This is a change on Windows, which would use 3 digits.
2267 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2268 so that any alterations it does to the resulting string will be
2269 available in stringlib/formatter.h (for float.__format__).
2270
Eric Smith5a3c1352008-02-19 13:21:56 +00002271- Implemented PEP 3101, Advanced String Formatting. This adds a new
2272 builtin format(); a format() method for str and unicode; a
2273 __format__() method to object, str, unicode, int, long, float, and
2274 datetime; the class string.Formatter; and the C API
2275 PyObject_Format().
2276
Georg Brandl3ee81df2008-05-17 18:14:43 +00002277- Fixed several potential crashes, all caused by specially crafted
2278 __del__ methods exploiting objects in temporarily inconsistent
2279 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002280
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002281- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002282 prevent a possible crash: an Abstract Base Class would try to access
2283 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002284
Georg Brandl3ee81df2008-05-17 18:14:43 +00002285- Fixed repr() and str() of complex numbers with infinity or nan as
2286 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002288- Clear all free lists during a gc.collect() of the highest generation
2289 in order to allow pymalloc to free more arenas. Python may give back
2290 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002291
Georg Brandl3ee81df2008-05-17 18:14:43 +00002292- Issue #2045: Fix an infinite recursion triggered when printing a
2293 subclass of collections.defaultdict, if its default_factory is set
2294 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002295
Christian Heimesf75dbef2008-02-08 00:11:31 +00002296- Fixed a minor memory leak in dictobject.c. The content of the free
2297 list was not freed on interpreter shutdown.
2298
Georg Brandl3ee81df2008-05-17 18:14:43 +00002299- Limit free list of method and builtin function objects to 256
2300 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002301
Georg Brandl3ee81df2008-05-17 18:14:43 +00002302- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2303 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002304 to compact the internal free lists of pre-allocted ints and floats.
2305
Georg Brandl3ee81df2008-05-17 18:14:43 +00002306- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2307 calls. Python expected the return type int but the fork familie
2308 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002309
Georg Brandl3ee81df2008-05-17 18:14:43 +00002310- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2311 appear in the same code unit.

2320 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002321
Georg Brandl3ee81df2008-05-17 18:14:43 +00002322- Patch #1473257: generator objects gain a gi_code attribute. This is
2323 the same object as the func_code attribute of the function that
2324 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002325
Georg Brandl3ee81df2008-05-17 18:14:43 +00002326- Issue #1920: "while 0" statements were completely removed by the
2327 compiler, even in the presence of an "else" clause, which is
2328 supposed to be run when the condition is false. Now the compiler
2329 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002330
Guido van Rossumeead05f2008-01-24 18:21:02 +00002331- A few crashers fixed: weakref_in_del.py (issue #1377858);

2333 borrowed_ref_[34].py (not in tracker).
2334
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002335- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002336 suppressed while an extension is loaded by calling SetErrorMode in

2338
Georg Brandl3ee81df2008-05-17 18:14:43 +00002339- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002340 several extension methods and modules do not work without unicode
2341 support.
2342
Georg Brandl26543b12008-01-21 18:36:51 +00002343- Issue #1882: when compiling code from a string, encoding cookies in the
2344 second line of code were not always recognized correctly.
2345
Georg Brandl14404b62008-01-19 19:27:05 +00002346- Issue #1679: "0x" was taken as a valid integer literal.
2347
Georg Brandl6caad7d2008-01-26 14:19:22 +00002348- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002349 added.
2350
Christian Heimesc94e2b52008-01-14 04:13:37 +00002351- sys.float_info / PyFloat_GetInfo: The floating point information
2352 object was converted from a dict to a specialized structseq object.
2353
Georg Brandl3ee81df2008-05-17 18:14:43 +00002354- Patch #1816: Added sys.flags structseq. It exposes the status of
2355 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002356
Georg Brandl3ee81df2008-05-17 18:14:43 +00002357- Objects/structseq.c: Implemented new structseq representation. The

2370 envvar and sys.dont_write_bytecode attribute. All these can be set
2371 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002373- Improve some exception messages when Windows fails to load an
2374 extension module. Now we get for example '%1 is not a valid Win32
2375 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002376

Christian Heimes0a8143f2007-12-18 23:22:54 +00002382- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002383 and INF. float("nan"), float("inf") and float("-inf") now work on
2384 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002385
Georg Brandl3ee81df2008-05-17 18:14:43 +00002386- Compiler now generates simpler and faster code for dictionary
2387 literals. The oparg for BUILD_MAP now indicates an estimated
2388 dictionary size. There is a new opcode, STORE_MAP, for adding
2389 entries to the dictionary.

2407 running, and if the deallocation of its frames somehow calls the
2408 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002409

Georg Brandl3ee81df2008-05-17 18:14:43 +00002418- Patch #1739468: Directories and zipfiles containing a __main__.py
2419 file can now be directly executed by passing their name to the
2420 interpreter. The directory/zipfile is automatically inserted as the
2421 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002422
Georg Brandl3ee81df2008-05-17 18:14:43 +00002423- Issue #1265: Fix a problem with sys.settrace, if the tracing
2424 function uses a generator expression when at the same time the
2425 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002426
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002427- sets and frozensets now have an isdisjoint() method.
2428

2430
Neal Norwitz44f326e2007-10-05 05:29:17 +00002431- Fix warnings found by the new version of the Coverity checker.
2432
Georg Brandl3ee81df2008-05-17 18:14:43 +00002433- The enumerate() builtin function is no longer bounded to sequences
2434 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2435 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002436
Georg Brandl3ee81df2008-05-17 18:14:43 +00002437- Issue #1686386: Tuple's tp_repr did not take into account the
2438 possibility of having a self-referential tuple, which is possible
2439 from C code. Nor did object's tp_str consider that a type's tp_str
2440 could do something that could lead to an inifinite recursion.
2441 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2442 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002443
Georg Brandl3ee81df2008-05-17 18:14:43 +00002444- Issue #1164: It was possible to trigger deadlock when using the
2445 'print' statement to write to a file since the GIL was not released
2446 as needed. Now PyObject_Print() does the right thing along with
2447 various tp_print implementations of the built-in types and those in
2448 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002449
Georg Brandl3ee81df2008-05-17 18:14:43 +00002450- Issue #1147: Exceptions were directly allowing string exceptions in
2451 their throw() method even though string exceptions no longer
2452 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002453
Georg Brandl3ee81df2008-05-17 18:14:43 +00002454- Issue #1096: Prevent a segfault from getting the repr of a very
2455 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002456
Brett Cannon1e534b52007-09-07 04:18:30 +00002457- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002458 PyObject_Call() never calling back out to Python code to trigger
2459 recursion depth updates/checks. Required the creation of a static
2460 RuntimeError instance in case normalizing an exception put the
2461 recursion check value past its limit. Fixes crashers
2462 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002463
Georg Brandl3ee81df2008-05-17 18:14:43 +00002464- Patch #1031213: Decode source line in SyntaxErrors back to its

2468 with %G.
2469
Georg Brandl3ee81df2008-05-17 18:14:43 +00002470- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00002477- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002478 __*__ attributes. (Some already existed, e.g., __doc__ and
2479 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002480
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002481- Add -3 option to the interpreter to warn about features that are
2482 deprecated and will be changed/removed in Python 3.0.
2483
Georg Brandl2134e752007-05-21 20:34:16 +00002484- Patch #1686487: you can now pass any mapping after '**' in function
2485 calls.
2486
Collin Winter62903052007-05-18 23:11:24 +00002487- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002488 "except E as target:". This is to provide forwards compatibility
2489 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002490
Brett Cannon229cee22007-05-05 01:34:02 +00002491- Deprecate BaseException.message as per PEP 352.
2492
Georg Brandl3ee81df2008-05-17 18:14:43 +00002493- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002494 inherited from a builtin base.
2495
Vinay Sajip8549ce32007-05-06 17:53:37 +00002496- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002497 setting a plain string, ie don't expand to single letter identifiers.
2498
Raymond Hettinger13936692007-04-11 18:40:58 +00002499- Request #1191699: Slices can now be pickled.
2500
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002501- Request #1193128: str.translate() now allows a None argument for
2502 translations that only remove characters without re-mapping the
2503 remaining characters.
2504
Georg Brandl5cb76c12007-03-21 09:00:39 +00002505- Patch #1682205: a TypeError while unpacking an iterable is no longer
2506 masked by a generic one with the message "unpack non-sequence".
2507
Neal Norwitzaa754b72007-03-21 06:39:48 +00002508- Remove unused file Python/fmod.c.
2509
Guido van Rossum143b5642007-03-23 04:58:42 +00002510- Bug #1683368: The object.__init__() and object.__new__() methods are
2511 now stricter in rejecting excess arguments. The only time when
2512 either allows excess arguments is when it is not overridden and the
2513 other one is. For backwards compatibility, when both are
2514 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002515 warning later). Also, type.__init__() insists on the same signature
2516 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002517
Georg Brandl3ee81df2008-05-17 18:14:43 +00002518- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2519 object to complex using its __complex__() method before falling back
2520 to the __float__() method. Therefore, the functions in the cmath
2521 module now can operate on objects that define a __complex__()
2522 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002523
Georg Brandl3ee81df2008-05-17 18:14:43 +00002524- Patch #1623563: allow __class__ assignment for classes with
2525 __slots__. The old and the new class are still required to have the
2526 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002527
Georg Brandl3ee81df2008-05-17 18:14:43 +00002528- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002531- Patch #1462488: Python no longer segfaults when
2532 ``object.__reduce_ex__()`` is called with an object that is faking
2533 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002534
Georg Brandl3ee81df2008-05-17 18:14:43 +00002535- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002538- Patch #1444529: the builtin compile() now accepts keyword arguments.
2539
Georg Brandl7b9c5552007-03-12 14:30:05 +00002540- Bug #1678647: write a newline after printing an exception in any
2541 case, even when converting the value to a string failed.
2542
Georg Brandl871f1bc2007-03-12 13:17:36 +00002543- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002544 its argument, if it exists. If not, it will work like before. This
2545 allows customizing the output of dir() in the presence of a
2546 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002547
Collin Winter276887b2007-03-12 16:11:39 +00002548- Patch #922167: Python no longer segfaults when faced with infinitely
2549 self-recursive reload() calls (as reported by bug #742342).
2550
Georg Brandl3ee81df2008-05-17 18:14:43 +00002551- Patch #1675981: remove unreachable code from ``type.__new__()``
2552 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002554- Patch #1491866: change the complex() constructor to allow
2555 parthensized forms. This means complex(repr(x)) now works instead of
2556 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002557
Georg Brandlaa2321b2007-03-07 00:40:28 +00002558- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002559 makes the filenames the warning module prints much more sensible
2560 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002561
Georg Brandl49aafc92007-03-07 00:34:46 +00002562- Variant of patch #697613: don't exit the interpreter on a SystemExit
2563 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002564 variable is given, but break into the interactive interpreter just
2565 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002573- Patch #1674228: when assigning a slice (old-style), check for the
2574 sq_ass_slice instead of the sq_slice slot.
2575
Georg Brandl3ee81df2008-05-17 18:14:43 +00002576- When printing an unraisable error, don't print exceptions. before
2577 the name. This duplicates the behavior whening normally printing
2578 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002579
Georg Brandl3ee81df2008-05-17 18:14:43 +00002580- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00003111 AttributeError instead of an IOError when the server's response
3112 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003113

Georg Brandl3ee81df2008-05-17 18:14:43 +00003129- Patch #1530482: add pydoc.render_doc() which returns the

3144
Georg Brandl92a6bae2007-03-13 17:43:32 +00003145- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003146 are set for invalid interpolation sequences that would lead to
3147 errors on reading back those values.

3190 returned string up to the first NUL character.

3201
Georg Brandl3ee81df2008-05-17 18:14:43 +00003202- unittest now verifies more of its assumptions. In particular,
3203 TestCase and TestSuite subclasses (not instances) are no longer
3204 accepted in TestSuite.addTest(). This should cause no
3205 incompatibility since it never made sense with ordinary subclasses
3206 -- the failure just occurred later, with a more cumbersome
3207 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003494 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00003596 time so that opening a database previously created with the DB_DUP
3597 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3598 opens. Specifically: dictionary assignment to a DB object will
3599 replace all values for a given key when the database allows
3600 duplicate values. DB users should use DB.put(k, v) when they want
3601 to store duplicates; not DB[k] = v.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003881 periodic threadstate and signal checking in tight loops. By
3882 default, this option is turned-off. It should only be enabled in

Christian Heimes5b970ad2008-02-06 13:33:44 +00003940
Georg Brandl3ee81df2008-05-17 18:14:43 +00003941- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3942 to ``PyTuple_SetItem``, it can be used to populate a brand new

3955
Georg Brandl3ee81df2008-05-17 18:14:43 +00003956- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3957 of w# format code incorrectly truncated the length to an int, even
3958 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3959 incorrect results with huge strings.

3983 outside of pystate.c and should not be necessary.
3984
Georg Brandl3ee81df2008-05-17 18:14:43 +00003985- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3986 absolute imports. In earlier versions they might have used relative
3987 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003988
Georg Brandl3ee81df2008-05-17 18:14:43 +00003989- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3990 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003991
Georg Brandl3ee81df2008-05-17 18:14:43 +00003992- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004017- Removed the macfs module. It had been deprecated since Python 2.5.
4018 This lead to the deprecation of macostools.touched() as it relied
