716What's New in Python 2.6.1
717==========================
718
719*Release date: 04-Dec-2008*
720
721Core and Builtins
722-----------------
723
724- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
725 interpreter to abort ("Fatal Python error: Could not reset the stack!")
726 instead of throwing a MemoryError.
727
728- Issue #4367: Python would segfault during compiling when the unicodedata
729 module couldn't be imported and \N escapes were present.
730
731- Issue #4348: Some bytearray methods returned that didn't cause any change to
732 the bytearray, returned the same bytearray instead of a copy.
733
734- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
735
736- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
737
738- Issue #4048: The parser module now correctly validates relative imports.
739
740- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
741 exec statement.
742
743- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
744 method does not return iterators for the 4th and 5th items.
745
746- Issue #4209: Enabling unicode_literals and the print_function in the same
747 __future__ import didn't work.
748
749- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
750 returned a path longer than MAX_PATH. (But It's doubtful this code path is
751 really executed because I cannot move to such directory on win2k)
752
753- Issue #4069: When set.remove(element) is used with a set element, the element
754 is temporarily replaced with an equivalent frozenset. But the eventual
755 KeyError would always report the empty frozenset([]) as the missing key. Now
756 it correctly refers to the initial element.
757
758- Fixed C99 style comments in several files. Python is now C89 compatible
759 again.

907
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000908- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
909 PyString_FromFormat or PyErr_Format to display size_t values. The macro
910 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
911 ``printf`` function, whereas PyString_FromFormat has an independent

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

Antoine Pitrou0668c622008-08-26 22:42:08 +0000934 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
935 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1009 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1010 for catch_warnings() also led to an improvement in the raising of a
1011 DeprecationWarning related to warnings.warn_explicit().
1012

1031-----------------
1032
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001033- Issue #2975: When compiling several extension modules with Visual Studio 2008
1034 from the same python interpreter, some environment variables would grow
1035 without limit.
1036
Benjamin Peterson37346b22008-08-23 20:27:43 +00001037- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
1038 exploitation of poor argument checking.
1039

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001074What's New in Python 2.6 beta 3?
1075================================
1076
Barry Warsaw07a4a382008-08-21 01:15:08 +00001077*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001078
1079Core and Builtins
1080-----------------
1081
Guido van Rossumf8402962008-08-20 15:01:50 +00001082- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1083 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1084 extensions do not automatically benefit from the class attribute
1085 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1086 to their tp_flags field if they care. This is a backwards
1087 compatibility feature; in 3.0, all types will use the cache by
1088 default.
1089
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001090- Keyword arguments can now follow starred arguments. (``f(a, *args,
1091 keyword=23)`` is now valid syntax.)
1092
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001093- ctypes function pointers that are COM methods have a boolean True
1094 value again.
1095
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001096- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1097 by denying s# to parse objects that have a releasebuffer procedure,
1098 and introducing s*.
1099
Georg Brandl1e13ea92008-08-11 09:07:59 +00001100- Issue #3537: Fix an assertion failure when an empty but presized dict
1101 object was stored in the freelist.
1102
Mark Dickinsonb6467572008-08-04 21:30:09 +00001103- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1104 ValueError consistently across platforms.
1105
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001106- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1107 (64bit Unix, for example), unichr() would truncate its argument and return
1108 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1109
Neal Norwitze7d8be82008-07-31 17:17:14 +00001110- Apply security patches from Apple.
1111
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001112- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1113 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1114
Antoine Pitrou92f82162008-07-25 22:22:08 +00001115- Issue #1819: function calls with several named parameters are now on
1116 average 35% faster (as measured by pybench).
1117
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001118- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1119 the python debugger steps into a class statement: the free variables (local
1120 variables defined in an outer scope) would be deleted from the outer scope.
1121
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001122- Issue #2620: Overflow checking when allocating or reallocating memory
1123 was not always being done properly in some python types and extension
1124 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1125 all been updated to perform better checks and places in the code that
1126 would previously leak memory on the error path when such an allocation
1127 failed have been fixed.
1128
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001129Library
1130-------
1131
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001132- Issue #3612: Added some missing basic types in ctypes.wintypes.
1133
Benjamin Petersone977ad42008-08-20 01:42:01 +00001134- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1135 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1136
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001137- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1138 version reported by these tools does not necessarily follow the python
1139 version numbering scheme, so the module is less strict when parsing it.
1140
Nick Coghlanf70385a2008-08-18 12:42:46 +00001141- Issue #2235: Added Py3k warnings for types which will become unhashable
1142 under the stricter __hash__ inheritance rules in 3.0. Several types
1143 which did not meet the rules for hash invariants and were already
1144 unhashable in 3.0 have now been explicitly flagged as unhashable in
1145 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1146 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1147
Brett Cannon88f801d2008-08-18 00:46:22 +00001148- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1156
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001157- Issue #3575: Incremental decoder's decode function now takes bytearray
1158 by using 's*' instead of 't#'.
1159
Jesus Cea585ad8a2009-07-02 15:37:21 +00001160- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001161 fails unicode conversion on 2nd parameter. (windows only)
1162
Facundo Batista94f243a2008-08-17 03:38:39 +00001163- Issue 2464. urllib2 now supports a malformation in the URL received
1164 in a redirect.
1165
Brett Cannonabe423e2008-08-16 21:47:07 +00001166- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001167 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001168
Facundo Batistaeb90b782008-08-16 14:44:07 +00001169- Issue #2776: fixed small issue when handling an URL with double slash
1170 after a 302 response in the case of not going through a proxy.
1171
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001172- Issue #2676: in the email package, content-type parsing was hanging on
1173 pathological input because of quadratic or exponential behaviour of a
1174 regular expression.
1175
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001176- Issue #3476: binary buffered reading through the new "io" library is now
1177 thread-safe.
1178
Brett Cannonbf3157b2008-08-14 05:00:03 +00001179- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1180 since mimetools itself is deprecated. Because modules are cached, all
1181 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1182
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001183- Issue #3134: shutil referenced undefined WindowsError symbol.
1184
Robert Schuppenies14646332008-08-10 11:01:53 +00001185- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1186 menu entries were not deleted.
1187
Brett Cannon83e81842008-08-09 23:30:55 +00001188- Copied the implementation of reduce() to _functools.reduce() to have a
1189 version that did not raise a DeprecationWarning under -3.
1190
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001191- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1192 a MemoryError rather than silently stop the iteration.
1193
Guido van Rossum59ce9012008-08-09 14:55:34 +00001194- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1195 to _sre.compile() will now be rejected. This should not affect anybody
1196 since the re.compile() function never generates invalid re-bytecode.
1197
Skip Montanaroa032bf42008-08-08 22:52:51 +00001198- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Brett Cannon3aa2a492008-08-06 22:28:09 +00001202- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1203 the reload() built-in has been removed.
1204

Antoine Pitroude781a42008-08-09 12:43:23 +00001217 asking for a specific length. This problem only affected files opened
1218 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001219

1244 file name rather than a ZipInfo instance, so files are extracted with
1245 mode 0600 rather than 000 under Unix.
1246
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001247- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1248 argument in python 2.5, this broke code that subclassed Popen to include its

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001268What's New in Python 2.6 beta 2?
1269================================
1270
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001271*Release date: 17-Jul-2008*
1272
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001273Core and Builtins
1274-----------------
1275
Georg Brandl3e483f62008-07-16 22:57:41 +00001276- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1277 its methods now allow for items objects that can be converted to
1278 an integer using operator.index().
1279
Mark Dickinson64b7e502008-07-16 09:40:03 +00001280- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1281 produced a ValueError instead of giving the correct float.
1282
Eric Smitha5fa5a22008-07-16 00:11:49 +00001283- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1284 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1285
Mark Dickinson7103aa42008-07-15 19:08:33 +00001286- Issue #3008: the float type has a new instance method 'float.hex'
1287 and a new class method 'float.fromhex' to convert floating-point
1288 numbers to and from hexadecimal strings, respectively.
1289
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001290- Issue #2235: __hash__ is once again inherited by default. To allow
1291 collections.Hashable to remain meaningful in the presence of the
1292 default hash implementation (object.__hash__), it is now possible
1293 to explicit block inheritance of hash by setting __hash__=None at
1294 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1295 level.
1296
Nick Coghlanb028f502008-07-13 14:52:36 +00001297- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1298 the parent module cannot be found while performing an absolute import.
1299 This means that an incorrectly defined __package__ attribute will
1300 now only prevent relative imports in that module rather than causing
1301 all imports from that module to fail.
1302
Nick Coghlan14ff9942008-07-08 14:21:42 +00001303- Issue #2517: Allow unicode messages in Exceptions again by correctly
1304 bypassing the instance dictionary when looking up __unicode__ on
1305 new-style classes.
1306
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001307- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1308 set to a custom object whose write() method happens to install
1309 another file in sys.stdout.
1310
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001311- Issue #3088: Corrected a race condition in classes derived from
1312 threading.local: the first member set by a thread could be saved in
1313 another thread's dictionary.
1314
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001315- Issue #3004: Minor change to slice.indices(): the start and stop
1316 arguments are now treated identically, making the behaviour easier
1317 to describe and understand. For example, slice(None, -10,
1318 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1319 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1320 10, -1).
1321
Georg Brandl278fc502008-07-19 12:46:12 +00001322- Issue #3219: Calling a function with repeated keyword arguments,
1323 f(a=2, a=23), would not cause a syntax error. This was a regression
1324 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001325
Georg Brandl278fc502008-07-19 12:46:12 +00001326- Issue #2862: Make int and float freelist management consistent with
1327 other freelists. Changes their CompactFreeList apis into
1328 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001329
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001330Library
1331-------
1332
Thomas Heller57adf222008-08-14 19:10:48 +00001333- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1334 api functions without holding the GIL, which could lead to a fatal
1335 error when they failed.
1336
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001337- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
1338

1344
Jesse Noller13e9d582008-07-16 14:32:36 +00001345- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1346 ForkingPickler.register() to resolve conflict with ctypes.
1347
Vinay Sajip51e65192008-07-18 09:01:10 +00001348- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001349
Thomas Heller880f5292008-07-15 19:39:38 +00001350- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1351 a valid dlerror() message.
1352
Thomas Heller2bad6572008-07-15 17:19:50 +00001353- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1354 incomplete structure was created.
1355
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001356- Issue #3339: dummy_thread.acquire() should not return None.
1357
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001358- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1359
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001360- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001361
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001362- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1363 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001364 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001365 content-length. The problem had been corrected in the 2.4 branch, but never
1366 merged into trunk.
1367
Georg Brandle78fbcc2008-07-05 10:13:36 +00001368- Issue #2663: add filtering capability to shutil.copytree().

1371
1372- Issue #1526: Allow more than 64k files to be added to Zip64 file.
1373
1374- Issue #1746: Correct handling of zipfile archive comments (previously
1375 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00001376 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00001377
Vinay Sajip51e65192008-07-18 09:01:10 +00001378- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001379 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00001380
Nick Coghlanc060b0e2008-07-02 13:09:19 +00001381- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1382 handling is now the same as that of other special attributes like __name__).
1383
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001384- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
1385 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00001836- Issue #1631171: Re-implement the 'warnings' module in C (the
1837 original Python code has been kept as backup). This will allow for
1838 using the 'warning's machinery in such places as the parser where
1839 use of pure Python code is not possible. Both the ``showarning()``
1840 and ``formatwarning()`` gain an optional 'line' argument which is
1841 not called by default for backwards-compatibility reasons. Setting
1842 ``warnings.showwarning()`` to an implementation that lacks support
1843 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001906- Issue #2550: The approach used by client/server code for obtaining
1907 ports to listen on in network-oriented tests has been refined in an
1908 effort to facilitate running multiple instances of the entire
1909 regression test suite in parallel without issue.
1910 test_support.bind_port() has been fixed such that it will always
1911 return a unique port -- which wasn't always the case with the
1912 previous implementation, especially if socket options had been set
1913 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1914 new implementation of bind_port() will actually raise an exception
1915 if it is passed an AF_INET/SOCK_STREAM socket with either the
1916 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1917 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1918 the socket it's been passed. This currently only applies to
1919 Windows. This option prevents any other sockets from binding to the
1920 host/port we've bound to, thus removing the possibility of the
1921 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1922 when a second SOCK_STREAM socket binds and accepts to a host/port
1923 that's already been bound by another socket. The optional preferred
1924 port parameter to bind_port() has been removed. Under no
1925 circumstances should tests be hard coding ports!
1926
1927 test_support.find_unused_port() has also been introduced, which will
1928 pass a temporary socket object to bind_port() in order to obtain an
1929 unused port. The temporary socket object is then closed and
1930 deleted, and the port is returned. This method should only be used
1931 for obtaining an unused port in order to pass to an external program
1932 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1933 a parameter to a server-oriented class that doesn't give you direct
1934 access to the underlying socket used.
1935
1936 Finally, test_support.HOST has been introduced, which should be used
1937 for the host argument of any relevant socket calls (i.e. bind and
1938 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001939
1940 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001941 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001942 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1943 test_asynchat and test_socket_ssl.
1944
Georg Brandl3ee81df2008-05-17 18:14:43 +00001945 It is now possible for multiple instances of the regression test
1946 suite to run in parallel without issue.

2102 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00002103 platform.machine() and platform.processor() will report this
2104 information as well.

2212Core and builtins
2213-----------------
2214
Fred Drakea8ee94b2008-03-01 02:45:07 +00002215- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002216 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002217
Georg Brandlad61bc82008-02-23 15:11:18 +00002218- Issue #2067: file.__exit__() now calls subclasses' close() method.
2219
2220- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002221
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002222- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002223 issue 215555 for a discussion.
2224
Eric Smitha73fbe72008-02-23 03:09:44 +00002225- Added the future_builtins module, which contains hex() and oct().
2226 These are the PEP 3127 version of these functions, designed to be
2227 compatible with the hex() and oct() builtins from Python 3.0. They
2228 differ slightly in their output formats from the existing, unchanged
2229 Python 2.6 builtins. The expected usage of the future_builtins
2230 module is:
2231 from future_builtins import hex, oct
2232
Eric Smith7ef40bf2008-02-20 23:34:22 +00002233- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2234 exponents for exponents with absolute value < 100. Follows C99
2235 standard. This is a change on Windows, which would use 3 digits.
2236 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2237 so that any alterations it does to the resulting string will be
2238 available in stringlib/formatter.h (for float.__format__).
2239
Eric Smith5a3c1352008-02-19 13:21:56 +00002240- Implemented PEP 3101, Advanced String Formatting. This adds a new
2241 builtin format(); a format() method for str and unicode; a
2242 __format__() method to object, str, unicode, int, long, float, and
2243 datetime; the class string.Formatter; and the C API
2244 PyObject_Format().
2245
Georg Brandl3ee81df2008-05-17 18:14:43 +00002246- Fixed several potential crashes, all caused by specially crafted
2247 __del__ methods exploiting objects in temporarily inconsistent
2248 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002249
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002250- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002251 prevent a possible crash: an Abstract Base Class would try to access
2252 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002253
Georg Brandl3ee81df2008-05-17 18:14:43 +00002254- Fixed repr() and str() of complex numbers with infinity or nan as
2255 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002257- Clear all free lists during a gc.collect() of the highest generation
2258 in order to allow pymalloc to free more arenas. Python may give back
2259 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002260
Georg Brandl3ee81df2008-05-17 18:14:43 +00002261- Issue #2045: Fix an infinite recursion triggered when printing a
2262 subclass of collections.defaultdict, if its default_factory is set
2263 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002264
Christian Heimesf75dbef2008-02-08 00:11:31 +00002265- Fixed a minor memory leak in dictobject.c. The content of the free
2266 list was not freed on interpreter shutdown.
2267
Georg Brandl3ee81df2008-05-17 18:14:43 +00002268- Limit free list of method and builtin function objects to 256
2269 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002270
Georg Brandl3ee81df2008-05-17 18:14:43 +00002271- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2272 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002273 to compact the internal free lists of pre-allocted ints and floats.
2274
Georg Brandl3ee81df2008-05-17 18:14:43 +00002275- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2276 calls. Python expected the return type int but the fork familie
2277 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002278
Georg Brandl3ee81df2008-05-17 18:14:43 +00002279- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2280 appear in the same code unit.

2289 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002290
Georg Brandl3ee81df2008-05-17 18:14:43 +00002291- Patch #1473257: generator objects gain a gi_code attribute. This is
2292 the same object as the func_code attribute of the function that
2293 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002294
Georg Brandl3ee81df2008-05-17 18:14:43 +00002295- Issue #1920: "while 0" statements were completely removed by the
2296 compiler, even in the presence of an "else" clause, which is
2297 supposed to be run when the condition is false. Now the compiler
2298 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002299
Guido van Rossumeead05f2008-01-24 18:21:02 +00002300- A few crashers fixed: weakref_in_del.py (issue #1377858);
2301 loosing_dict_ref.py (issue #1303614, test67.py);
2302 borrowed_ref_[34].py (not in tracker).
2303
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002304- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002305 suppressed while an extension is loaded by calling SetErrorMode in
2306 dynload_win.c. The error is still reported properly.
2307
Georg Brandl3ee81df2008-05-17 18:14:43 +00002308- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002309 several extension methods and modules do not work without unicode
2310 support.
2311
Georg Brandl26543b12008-01-21 18:36:51 +00002312- Issue #1882: when compiling code from a string, encoding cookies in the
2313 second line of code were not always recognized correctly.
2314
Georg Brandl14404b62008-01-19 19:27:05 +00002315- Issue #1679: "0x" was taken as a valid integer literal.
2316
Georg Brandl6caad7d2008-01-26 14:19:22 +00002317- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002318 added.
2319
Christian Heimesc94e2b52008-01-14 04:13:37 +00002320- sys.float_info / PyFloat_GetInfo: The floating point information
2321 object was converted from a dict to a specialized structseq object.
2322
Georg Brandl3ee81df2008-05-17 18:14:43 +00002323- Patch #1816: Added sys.flags structseq. It exposes the status of
2324 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002325
Georg Brandl3ee81df2008-05-17 18:14:43 +00002326- Objects/structseq.c: Implemented new structseq representation. The
2327 patch makes structseqs (e.g. the return value of os.stat) more
2328 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002329
Georg Brandl3ee81df2008-05-17 18:14:43 +00002330- Patch #1700288: added a type attribute cache that caches method
2331 accesses, resulting in speedups in heavily object-oriented code.

2339 envvar and sys.dont_write_bytecode attribute. All these can be set
2340 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002342- Improve some exception messages when Windows fails to load an
2343 extension module. Now we get for example '%1 is not a valid Win32
2344 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002345
Georg Brandl3ee81df2008-05-17 18:14:43 +00002346- Bug #1481296: Fixed long(float('nan')) != 0L.

Christian Heimes0a8143f2007-12-18 23:22:54 +00002351- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002352 and INF. float("nan"), float("inf") and float("-inf") now work on
2353 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002354
Georg Brandl3ee81df2008-05-17 18:14:43 +00002355- Compiler now generates simpler and faster code for dictionary
2356 literals. The oparg for BUILD_MAP now indicates an estimated
2357 dictionary size. There is a new opcode, STORE_MAP, for adding
2358 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002387- Patch #1739468: Directories and zipfiles containing a __main__.py
2388 file can now be directly executed by passing their name to the
2389 interpreter. The directory/zipfile is automatically inserted as the
2390 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002391
Georg Brandl3ee81df2008-05-17 18:14:43 +00002392- Issue #1265: Fix a problem with sys.settrace, if the tracing
2393 function uses a generator expression when at the same time the
2394 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002395
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002396- sets and frozensets now have an isdisjoint() method.
2397

2401
Georg Brandl3ee81df2008-05-17 18:14:43 +00002402- The enumerate() builtin function is no longer bounded to sequences
2403 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2404 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002405
Georg Brandl3ee81df2008-05-17 18:14:43 +00002406- Issue #1686386: Tuple's tp_repr did not take into account the
2407 possibility of having a self-referential tuple, which is possible
2408 from C code. Nor did object's tp_str consider that a type's tp_str
2409 could do something that could lead to an inifinite recursion.
2410 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2411 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002412
Georg Brandl3ee81df2008-05-17 18:14:43 +00002413- Issue #1164: It was possible to trigger deadlock when using the
2414 'print' statement to write to a file since the GIL was not released
2415 as needed. Now PyObject_Print() does the right thing along with
2416 various tp_print implementations of the built-in types and those in
2417 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002418
Georg Brandl3ee81df2008-05-17 18:14:43 +00002419- Issue #1147: Exceptions were directly allowing string exceptions in
2420 their throw() method even though string exceptions no longer
2421 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002422
Georg Brandl3ee81df2008-05-17 18:14:43 +00002423- Issue #1096: Prevent a segfault from getting the repr of a very
2424 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002425
Brett Cannon1e534b52007-09-07 04:18:30 +00002426- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002427 PyObject_Call() never calling back out to Python code to trigger
2428 recursion depth updates/checks. Required the creation of a static
2429 RuntimeError instance in case normalizing an exception put the
2430 recursion check value past its limit. Fixes crashers
2431 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002432
Georg Brandl3ee81df2008-05-17 18:14:43 +00002433- Patch #1031213: Decode source line in SyntaxErrors back to its

2437 with %G.
2438
Georg Brandl3ee81df2008-05-17 18:14:43 +00002439- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00002446- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002447 __*__ attributes. (Some already existed, e.g., __doc__ and
2448 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002449
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002450- Add -3 option to the interpreter to warn about features that are
2451 deprecated and will be changed/removed in Python 3.0.
2452
Georg Brandl2134e752007-05-21 20:34:16 +00002453- Patch #1686487: you can now pass any mapping after '**' in function
2454 calls.
2455
Collin Winter62903052007-05-18 23:11:24 +00002456- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002457 "except E as target:". This is to provide forwards compatibility
2458 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002459
Brett Cannon229cee22007-05-05 01:34:02 +00002460- Deprecate BaseException.message as per PEP 352.
2461
Georg Brandl3ee81df2008-05-17 18:14:43 +00002462- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002463 inherited from a builtin base.
2464
Vinay Sajip8549ce32007-05-06 17:53:37 +00002465- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002466 setting a plain string, ie don't expand to single letter identifiers.
2467
Raymond Hettinger13936692007-04-11 18:40:58 +00002468- Request #1191699: Slices can now be pickled.
2469
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002470- Request #1193128: str.translate() now allows a None argument for
2471 translations that only remove characters without re-mapping the
2472 remaining characters.
2473
Georg Brandl5cb76c12007-03-21 09:00:39 +00002474- Patch #1682205: a TypeError while unpacking an iterable is no longer
2475 masked by a generic one with the message "unpack non-sequence".
2476
Neal Norwitzaa754b72007-03-21 06:39:48 +00002477- Remove unused file Python/fmod.c.
2478
Guido van Rossum143b5642007-03-23 04:58:42 +00002479- Bug #1683368: The object.__init__() and object.__new__() methods are
2480 now stricter in rejecting excess arguments. The only time when
2481 either allows excess arguments is when it is not overridden and the
2482 other one is. For backwards compatibility, when both are
2483 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002484 warning later). Also, type.__init__() insists on the same signature
2485 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002486
Georg Brandl3ee81df2008-05-17 18:14:43 +00002487- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2488 object to complex using its __complex__() method before falling back
2489 to the __float__() method. Therefore, the functions in the cmath
2490 module now can operate on objects that define a __complex__()
2491 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002492
Georg Brandl3ee81df2008-05-17 18:14:43 +00002493- Patch #1623563: allow __class__ assignment for classes with
2494 __slots__. The old and the new class are still required to have the
2495 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002496
Georg Brandl3ee81df2008-05-17 18:14:43 +00002497- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002500- Patch #1462488: Python no longer segfaults when
2501 ``object.__reduce_ex__()`` is called with an object that is faking
2502 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002503
Georg Brandl3ee81df2008-05-17 18:14:43 +00002504- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002507- Patch #1444529: the builtin compile() now accepts keyword arguments.
2508
Georg Brandl7b9c5552007-03-12 14:30:05 +00002509- Bug #1678647: write a newline after printing an exception in any
2510 case, even when converting the value to a string failed.
2511
Georg Brandl871f1bc2007-03-12 13:17:36 +00002512- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002513 its argument, if it exists. If not, it will work like before. This
2514 allows customizing the output of dir() in the presence of a
2515 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002516
Collin Winter276887b2007-03-12 16:11:39 +00002517- Patch #922167: Python no longer segfaults when faced with infinitely
2518 self-recursive reload() calls (as reported by bug #742342).
2519
Georg Brandl3ee81df2008-05-17 18:14:43 +00002520- Patch #1675981: remove unreachable code from ``type.__new__()``
2521 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002523- Patch #1491866: change the complex() constructor to allow
2524 parthensized forms. This means complex(repr(x)) now works instead of
2525 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002526
Georg Brandlaa2321b2007-03-07 00:40:28 +00002527- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002528 makes the filenames the warning module prints much more sensible
2529 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002530
Georg Brandl49aafc92007-03-07 00:34:46 +00002531- Variant of patch #697613: don't exit the interpreter on a SystemExit
2532 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002533 variable is given, but break into the interactive interpreter just
2534 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00002541
Georg Brandl0fca97a2007-03-05 22:28:08 +00002542- Patch #1674228: when assigning a slice (old-style), check for the
2543 sq_ass_slice instead of the sq_slice slot.
2544
Georg Brandl3ee81df2008-05-17 18:14:43 +00002545- When printing an unraisable error, don't print exceptions. before
2546 the name. This duplicates the behavior whening normally printing
2547 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002548
Georg Brandl3ee81df2008-05-17 18:14:43 +00002549- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00003080 AttributeError instead of an IOError when the server's response
3081 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003082

Georg Brandl3ee81df2008-05-17 18:14:43 +00003098- Patch #1530482: add pydoc.render_doc() which returns the

3113
Georg Brandl92a6bae2007-03-13 17:43:32 +00003114- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003115 are set for invalid interpolation sequences that would lead to
3116 errors on reading back those values.

3170
Georg Brandl3ee81df2008-05-17 18:14:43 +00003171- unittest now verifies more of its assumptions. In particular,
3172 TestCase and TestSuite subclasses (not instances) are no longer
3173 accepted in TestSuite.addTest(). This should cause no
3174 incompatibility since it never made sense with ordinary subclasses
3175 -- the failure just occurred later, with a more cumbersome
3176 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003463 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00003565 time so that opening a database previously created with the DB_DUP
3566 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3567 opens. Specifically: dictionary assignment to a DB object will
3568 replace all values for a given key when the database allows
3569 duplicate values. DB users should use DB.put(k, v) when they want
3570 to store duplicates; not DB[k] = v.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003850 periodic threadstate and signal checking in tight loops. By
3851 default, this option is turned-off. It should only be enabled in

Christian Heimes5b970ad2008-02-06 13:33:44 +00003909
Georg Brandl3ee81df2008-05-17 18:14:43 +00003910- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3911 to ``PyTuple_SetItem``, it can be used to populate a brand new

3924
Georg Brandl3ee81df2008-05-17 18:14:43 +00003925- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3926 of w# format code incorrectly truncated the length to an int, even
3927 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3928 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003929
Georg Brandl3ee81df2008-05-17 18:14:43 +00003930- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

3952 outside of pystate.c and should not be necessary.
3953
Georg Brandl3ee81df2008-05-17 18:14:43 +00003954- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3955 absolute imports. In earlier versions they might have used relative
3956 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003957
Georg Brandl3ee81df2008-05-17 18:14:43 +00003958- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3959 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003960
Georg Brandl3ee81df2008-05-17 18:14:43 +00003961- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00003986- Removed the macfs module. It had been deprecated since Python 2.5.
3987 This lead to the deprecation of macostools.touched() as it relied
