372 an existing .py counterpart, override the co_filename attributes of all
373 code objects if the original filename is obsolete (which can happen if the
374 file has been renamed, moved, or if it is accessed through different paths).
375 Patch by Ziga Seilnacht and Jean-Paul Calderone.
376
Georg Brandl734373c2009-01-03 21:55:17 +0000377- Issue #4075: Use OutputDebugStringW in Py_FatalError.

411
Vinay Sajip6badbe92009-01-20 22:49:13 +0000412- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +0000413 method on file objects with closefd=False. The file descriptor is still
414 kept open but the file object behaves like a closed file. The ``FileIO``
415 object also got a new readonly attribute ``closefd``.
416
Georg Brandlfa71a902008-12-05 09:08:28 +0000417- Issue #3689: The list reversed iterator now supports __length_hint__

588 traditional 2.x file object.

621
622- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
623 302 conformant loader) will now work correctly in most cases (they
624 are still subject to the constraints that exist for all code running
625 from inside a module loaded via a PEP 302 loader and attempting to

784What's New in Python 2.6.1
785==========================
786
787*Release date: 04-Dec-2008*
788
789Core and Builtins
790-----------------
791
792- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
793 interpreter to abort ("Fatal Python error: Could not reset the stack!")
794 instead of throwing a MemoryError.
795
796- Issue #4367: Python would segfault during compiling when the unicodedata
797 module couldn't be imported and \N escapes were present.
798
799- Issue #4348: Some bytearray methods returned that didn't cause any change to
800 the bytearray, returned the same bytearray instead of a copy.
801
802- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
803
804- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
805
806- Issue #4048: The parser module now correctly validates relative imports.
807
808- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
809 exec statement.
810
811- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
812 method does not return iterators for the 4th and 5th items.
813
814- Issue #4209: Enabling unicode_literals and the print_function in the same
815 __future__ import didn't work.
816
817- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
818 returned a path longer than MAX_PATH. (But It's doubtful this code path is
819 really executed because I cannot move to such directory on win2k)
820
821- Issue #4069: When set.remove(element) is used with a set element, the element
822 is temporarily replaced with an equivalent frozenset. But the eventual
823 KeyError would always report the empty frozenset([]) as the missing key. Now
824 it correctly refers to the initial element.
825
826- Fixed C99 style comments in several files. Python is now C89 compatible
827 again.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000976- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
977 PyString_FromFormat or PyErr_Format to display size_t values. The macro
978 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
979 ``printf`` function, whereas PyString_FromFormat has an independent

Vinay Sajip35e3b032008-09-01 14:33:59 +0000998 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000999 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001001- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001002 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1003 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1004 when given a tuple of classes as second argument, were looking up
1005 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1006 type object.
1007
Neal Norwitz18aa3882008-08-24 05:04:52 +00001008- Fix crashes on memory allocation failure found with failmalloc.

1077 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1078 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001142What's New in Python 2.6 beta 3?
1143================================
1144
Barry Warsaw07a4a382008-08-21 01:15:08 +00001145*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001146
1147Core and Builtins
1148-----------------
1149
Guido van Rossumf8402962008-08-20 15:01:50 +00001150- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1151 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1152 extensions do not automatically benefit from the class attribute
1153 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1154 to their tp_flags field if they care. This is a backwards
1155 compatibility feature; in 3.0, all types will use the cache by
1156 default.
1157
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001158- Keyword arguments can now follow starred arguments. (``f(a, *args,
1159 keyword=23)`` is now valid syntax.)
1160
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001161- ctypes function pointers that are COM methods have a boolean True
1162 value again.
1163
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001164- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1165 by denying s# to parse objects that have a releasebuffer procedure,
1166 and introducing s*.
1167
Georg Brandl1e13ea92008-08-11 09:07:59 +00001168- Issue #3537: Fix an assertion failure when an empty but presized dict
1169 object was stored in the freelist.
1170
Mark Dickinsonb6467572008-08-04 21:30:09 +00001171- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1172 ValueError consistently across platforms.
1173
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001174- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1175 (64bit Unix, for example), unichr() would truncate its argument and return
1176 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1177
Neal Norwitze7d8be82008-07-31 17:17:14 +00001178- Apply security patches from Apple.
1179
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001180- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1181 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1182
Antoine Pitrou92f82162008-07-25 22:22:08 +00001183- Issue #1819: function calls with several named parameters are now on
1184 average 35% faster (as measured by pybench).
1185
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001186- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1187 the python debugger steps into a class statement: the free variables (local
1188 variables defined in an outer scope) would be deleted from the outer scope.
1189
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001190- Issue #2620: Overflow checking when allocating or reallocating memory
1191 was not always being done properly in some python types and extension
1192 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1193 all been updated to perform better checks and places in the code that
1194 would previously leak memory on the error path when such an allocation
1195 failed have been fixed.

1199
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001200- Issue #3612: Added some missing basic types in ctypes.wintypes.
1201
Benjamin Petersone977ad42008-08-20 01:42:01 +00001202- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1203 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1204
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001205- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1206 version reported by these tools does not necessarily follow the python
1207 version numbering scheme, so the module is less strict when parsing it.
1208
Nick Coghlanf70385a2008-08-18 12:42:46 +00001209- Issue #2235: Added Py3k warnings for types which will become unhashable
1210 under the stricter __hash__ inheritance rules in 3.0. Several types
1211 which did not meet the rules for hash invariants and were already
1212 unhashable in 3.0 have now been explicitly flagged as unhashable in
1213 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1214 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1215
Brett Cannon88f801d2008-08-18 00:46:22 +00001216- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1217 imported into the module but exposed as part of the module's API.
1218
Brett Cannon7b96f072008-08-18 00:41:11 +00001219- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1220
Brett Cannon46225e72008-08-18 00:36:52 +00001221- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001223- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1224
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001225- Issue #3575: Incremental decoder's decode function now takes bytearray
1226 by using 's*' instead of 't#'.
1227
Jesus Cea585ad8a2009-07-02 15:37:21 +00001228- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001229 fails unicode conversion on 2nd parameter. (windows only)
1230
Facundo Batista94f243a2008-08-17 03:38:39 +00001231- Issue 2464. urllib2 now supports a malformation in the URL received
1232 in a redirect.
1233
Brett Cannonabe423e2008-08-16 21:47:07 +00001234- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001235 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001236
Facundo Batistaeb90b782008-08-16 14:44:07 +00001237- Issue #2776: fixed small issue when handling an URL with double slash
1238 after a 302 response in the case of not going through a proxy.
1239
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001240- Issue #2676: in the email package, content-type parsing was hanging on
1241 pathological input because of quadratic or exponential behaviour of a
1242 regular expression.
1243
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001244- Issue #3476: binary buffered reading through the new "io" library is now
1245 thread-safe.
1246
Brett Cannonbf3157b2008-08-14 05:00:03 +00001247- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1248 since mimetools itself is deprecated. Because modules are cached, all
1249 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1250
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001251- Issue #3134: shutil referenced undefined WindowsError symbol.
1252
Robert Schuppenies14646332008-08-10 11:01:53 +00001253- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1254 menu entries were not deleted.
1255
Brett Cannon83e81842008-08-09 23:30:55 +00001256- Copied the implementation of reduce() to _functools.reduce() to have a
1257 version that did not raise a DeprecationWarning under -3.
1258
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001259- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1260 a MemoryError rather than silently stop the iteration.
1261
Guido van Rossum59ce9012008-08-09 14:55:34 +00001262- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1263 to _sre.compile() will now be rejected. This should not affect anybody
1264 since the re.compile() function never generates invalid re-bytecode.
1265
Skip Montanaroa032bf42008-08-08 22:52:51 +00001266- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1267 upon first access it can be automatically initialized from the csv file if
1268 it wasn't initialized during instantiation.
1269
Brett Cannon3aa2a492008-08-06 22:28:09 +00001270- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1271 the reload() built-in has been removed.
1272
Brett Cannon7e30b672008-08-04 21:52:25 +00001273- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001274 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1342-----------------
1343
Georg Brandl3e483f62008-07-16 22:57:41 +00001344- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1345 its methods now allow for items objects that can be converted to
1346 an integer using operator.index().
1347
Mark Dickinson64b7e502008-07-16 09:40:03 +00001348- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1349 produced a ValueError instead of giving the correct float.
1350
Eric Smitha5fa5a22008-07-16 00:11:49 +00001351- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1352 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1353
Mark Dickinson7103aa42008-07-15 19:08:33 +00001354- Issue #3008: the float type has a new instance method 'float.hex'
1355 and a new class method 'float.fromhex' to convert floating-point
1356 numbers to and from hexadecimal strings, respectively.
1357
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001358- Issue #2235: __hash__ is once again inherited by default. To allow
1359 collections.Hashable to remain meaningful in the presence of the
1360 default hash implementation (object.__hash__), it is now possible
1361 to explicit block inheritance of hash by setting __hash__=None at
1362 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1363 level.
1364
Nick Coghlanb028f502008-07-13 14:52:36 +00001365- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1366 the parent module cannot be found while performing an absolute import.
1367 This means that an incorrectly defined __package__ attribute will
1368 now only prevent relative imports in that module rather than causing
1369 all imports from that module to fail.
1370
Nick Coghlan14ff9942008-07-08 14:21:42 +00001371- Issue #2517: Allow unicode messages in Exceptions again by correctly

1381 another thread's dictionary.
1382
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001383- Issue #3004: Minor change to slice.indices(): the start and stop
1384 arguments are now treated identically, making the behaviour easier
1385 to describe and understand. For example, slice(None, -10,
1386 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1387 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1388 10, -1).
1389
Georg Brandl278fc502008-07-19 12:46:12 +00001390- Issue #3219: Calling a function with repeated keyword arguments,
1391 f(a=2, a=23), would not cause a syntax error. This was a regression
1392 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001430- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1431 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001432 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001433 content-length. The problem had been corrected in the 2.4 branch, but never
1434 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001449- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1862- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00001863
1864- The PyString functions have been renamed to PyBytes. A batch of
1865 defines were added so that the linker still sees the original
1866 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001904- Issue #1631171: Re-implement the 'warnings' module in C (the
1905 original Python code has been kept as backup). This will allow for
1906 using the 'warning's machinery in such places as the parser where
1907 use of pure Python code is not possible. Both the ``showarning()``
1908 and ``formatwarning()`` gain an optional 'line' argument which is
1909 not called by default for backwards-compatibility reasons. Setting
1910 ``warnings.showwarning()`` to an implementation that lacks support
1911 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001936- The getpass module has been improved on Unix. It now uses /dev/tty
1937 by default and uses stderr instead of stdout. A GetPassWarning is
1938 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001953- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001954 extension modules between 32 and 64 bit platforms. See the distutls

1967 so the controlled environment will more closely mirror the typical
1968 script environment. This supports setup.py scripts that refer to
1969 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001974- Issue #2550: The approach used by client/server code for obtaining
1975 ports to listen on in network-oriented tests has been refined in an
1976 effort to facilitate running multiple instances of the entire
1977 regression test suite in parallel without issue.
1978 test_support.bind_port() has been fixed such that it will always
1979 return a unique port -- which wasn't always the case with the
1980 previous implementation, especially if socket options had been set
1981 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1982 new implementation of bind_port() will actually raise an exception
1983 if it is passed an AF_INET/SOCK_STREAM socket with either the
1984 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1985 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1986 the socket it's been passed. This currently only applies to
1987 Windows. This option prevents any other sockets from binding to the
1988 host/port we've bound to, thus removing the possibility of the
1989 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1990 when a second SOCK_STREAM socket binds and accepts to a host/port
1991 that's already been bound by another socket. The optional preferred
1992 port parameter to bind_port() has been removed. Under no
1993 circumstances should tests be hard coding ports!
1994
1995 test_support.find_unused_port() has also been introduced, which will
1996 pass a temporary socket object to bind_port() in order to obtain an
1997 unused port. The temporary socket object is then closed and
1998 deleted, and the port is returned. This method should only be used
1999 for obtaining an unused port in order to pass to an external program
2000 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2001 a parameter to a server-oriented class that doesn't give you direct
2002 access to the underlying socket used.
2003
2004 Finally, test_support.HOST has been introduced, which should be used
2005 for the host argument of any relevant socket calls (i.e. bind and
2006 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002007
2008 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002009 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002010 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2011 test_asynchat and test_socket_ssl.
2012
Georg Brandl3ee81df2008-05-17 18:14:43 +00002013 It is now possible for multiple instances of the regression test
2014 suite to run in parallel without issue.

2281-----------------
2282
Fred Drakea8ee94b2008-03-01 02:45:07 +00002283- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002284 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002289
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002290- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002291 issue 215555 for a discussion.
2292
Eric Smitha73fbe72008-02-23 03:09:44 +00002293- Added the future_builtins module, which contains hex() and oct().
2294 These are the PEP 3127 version of these functions, designed to be
2295 compatible with the hex() and oct() builtins from Python 3.0. They
2296 differ slightly in their output formats from the existing, unchanged
2297 Python 2.6 builtins. The expected usage of the future_builtins
2298 module is:
2299 from future_builtins import hex, oct
2300
Eric Smith7ef40bf2008-02-20 23:34:22 +00002301- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2302 exponents for exponents with absolute value < 100. Follows C99
2303 standard. This is a change on Windows, which would use 3 digits.
2304 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2305 so that any alterations it does to the resulting string will be
2306 available in stringlib/formatter.h (for float.__format__).
2307
Eric Smith5a3c1352008-02-19 13:21:56 +00002308- Implemented PEP 3101, Advanced String Formatting. This adds a new
2309 builtin format(); a format() method for str and unicode; a
2310 __format__() method to object, str, unicode, int, long, float, and
2311 datetime; the class string.Formatter; and the C API
2312 PyObject_Format().
2313
Georg Brandl3ee81df2008-05-17 18:14:43 +00002314- Fixed several potential crashes, all caused by specially crafted
2315 __del__ methods exploiting objects in temporarily inconsistent
2316 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002317
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002318- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002319 prevent a possible crash: an Abstract Base Class would try to access
2320 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002325- Clear all free lists during a gc.collect() of the highest generation
2326 in order to allow pymalloc to free more arenas. Python may give back
2327 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002328
Georg Brandl3ee81df2008-05-17 18:14:43 +00002329- Issue #2045: Fix an infinite recursion triggered when printing a
2330 subclass of collections.defaultdict, if its default_factory is set
2331 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002332
Christian Heimesf75dbef2008-02-08 00:11:31 +00002333- Fixed a minor memory leak in dictobject.c. The content of the free
2334 list was not freed on interpreter shutdown.
2335
Georg Brandl3ee81df2008-05-17 18:14:43 +00002336- Limit free list of method and builtin function objects to 256
2337 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002339- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2340 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002341 to compact the internal free lists of pre-allocted ints and floats.
2342
Georg Brandl3ee81df2008-05-17 18:14:43 +00002343- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2344 calls. Python expected the return type int but the fork familie
2345 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002346
Georg Brandl3ee81df2008-05-17 18:14:43 +00002347- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00002359- Patch #1473257: generator objects gain a gi_code attribute. This is
2360 the same object as the func_code attribute of the function that
2361 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002362
Georg Brandl3ee81df2008-05-17 18:14:43 +00002363- Issue #1920: "while 0" statements were completely removed by the
2364 compiler, even in the presence of an "else" clause, which is
2365 supposed to be run when the condition is false. Now the compiler
2366 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002367
Guido van Rossumeead05f2008-01-24 18:21:02 +00002368- A few crashers fixed: weakref_in_del.py (issue #1377858);

Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002372- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002373 suppressed while an extension is loaded by calling SetErrorMode in
2374 dynload_win.c. The error is still reported properly.
2375
Georg Brandl3ee81df2008-05-17 18:14:43 +00002376- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002377 several extension methods and modules do not work without unicode
2378 support.
2379
Georg Brandl26543b12008-01-21 18:36:51 +00002380- Issue #1882: when compiling code from a string, encoding cookies in the
2381 second line of code were not always recognized correctly.
2382
Georg Brandl14404b62008-01-19 19:27:05 +00002383- Issue #1679: "0x" was taken as a valid integer literal.
2384
Georg Brandl6caad7d2008-01-26 14:19:22 +00002385- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002386 added.
2387
Christian Heimesc94e2b52008-01-14 04:13:37 +00002388- sys.float_info / PyFloat_GetInfo: The floating point information
2389 object was converted from a dict to a specialized structseq object.
2390
Georg Brandl3ee81df2008-05-17 18:14:43 +00002391- Patch #1816: Added sys.flags structseq. It exposes the status of
2392 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002393
Georg Brandl3ee81df2008-05-17 18:14:43 +00002394- Objects/structseq.c: Implemented new structseq representation. The
2395 patch makes structseqs (e.g. the return value of os.stat) more
2396 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002397
Georg Brandl3ee81df2008-05-17 18:14:43 +00002398- Patch #1700288: added a type attribute cache that caches method
2399 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002400
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002401- Bug #1776: __import__() no longer accepts filenames on any platform.
2402 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002403
Georg Brandlaed6c662008-01-07 17:25:53 +00002404- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2405
Georg Brandl3ee81df2008-05-17 18:14:43 +00002406- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2407 envvar and sys.dont_write_bytecode attribute. All these can be set
2408 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002409
Georg Brandl3ee81df2008-05-17 18:14:43 +00002410- Improve some exception messages when Windows fails to load an
2411 extension module. Now we get for example '%1 is not a valid Win32
2412 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002413
Georg Brandl3ee81df2008-05-17 18:14:43 +00002414- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002416- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2417 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002418
Christian Heimes0a8143f2007-12-18 23:22:54 +00002419- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002420 and INF. float("nan"), float("inf") and float("-inf") now work on
2421 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002422
Georg Brandl3ee81df2008-05-17 18:14:43 +00002423- Compiler now generates simpler and faster code for dictionary
2424 literals. The oparg for BUILD_MAP now indicates an estimated
2425 dictionary size. There is a new opcode, STORE_MAP, for adding
2426 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002436- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002437 SystemError.
2438
Nick Coghlanef01d822007-12-03 12:55:17 +00002439- PEP 366: Allow explicit relative imports when executing modules

2444 running, and if the deallocation of its frames somehow calls the
2445 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002446

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00002450 attribute of an empty cell object.
2451
Georg Brandl3ee81df2008-05-17 18:14:43 +00002452- Issue #1460: The utf-7 incremental decoder did not accept truncated
2453 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002454
Georg Brandl3ee81df2008-05-17 18:14:43 +00002455- Patch #1739468: Directories and zipfiles containing a __main__.py
2456 file can now be directly executed by passing their name to the
2457 interpreter. The directory/zipfile is automatically inserted as the
2458 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002459
Georg Brandl3ee81df2008-05-17 18:14:43 +00002460- Issue #1265: Fix a problem with sys.settrace, if the tracing
2461 function uses a generator expression when at the same time the
2462 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002463
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002464- sets and frozensets now have an isdisjoint() method.
2465
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002466- optimize the performance of builtin.sum().
2467
Neal Norwitz44f326e2007-10-05 05:29:17 +00002468- Fix warnings found by the new version of the Coverity checker.
2469
Georg Brandl3ee81df2008-05-17 18:14:43 +00002470- The enumerate() builtin function is no longer bounded to sequences
2471 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2472 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002473
Georg Brandl3ee81df2008-05-17 18:14:43 +00002474- Issue #1686386: Tuple's tp_repr did not take into account the
2475 possibility of having a self-referential tuple, which is possible
2476 from C code. Nor did object's tp_str consider that a type's tp_str
2477 could do something that could lead to an inifinite recursion.
2478 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2479 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002480
Georg Brandl3ee81df2008-05-17 18:14:43 +00002481- Issue #1164: It was possible to trigger deadlock when using the
2482 'print' statement to write to a file since the GIL was not released
2483 as needed. Now PyObject_Print() does the right thing along with
2484 various tp_print implementations of the built-in types and those in
2485 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002486
Georg Brandl3ee81df2008-05-17 18:14:43 +00002487- Issue #1147: Exceptions were directly allowing string exceptions in
2488 their throw() method even though string exceptions no longer
2489 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002490
Georg Brandl3ee81df2008-05-17 18:14:43 +00002491- Issue #1096: Prevent a segfault from getting the repr of a very
2492 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002493
Brett Cannon1e534b52007-09-07 04:18:30 +00002494- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002495 PyObject_Call() never calling back out to Python code to trigger
2496 recursion depth updates/checks. Required the creation of a static
2497 RuntimeError instance in case normalizing an exception put the
2498 recursion check value past its limit. Fixes crashers
2499 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002500
Georg Brandl3ee81df2008-05-17 18:14:43 +00002501- Patch #1031213: Decode source line in SyntaxErrors back to its
2502 original source encoding.

Georg Brandl7c3b50d2007-07-12 08:38:00 +00002504- Patch #1673759: add a missing overflow check when formatting floats
2505 with %G.
2506
Georg Brandl3ee81df2008-05-17 18:14:43 +00002507- Prevent expandtabs() on string and unicode objects from causing a
2508 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00002509

Georg Brandl3ee81df2008-05-17 18:14:43 +00002512- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00002513
Neal Norwitz0ac60192007-05-27 04:08:54 +00002514- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002515 __*__ attributes. (Some already existed, e.g., __doc__ and
2516 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002517
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002518- Add -3 option to the interpreter to warn about features that are
2519 deprecated and will be changed/removed in Python 3.0.
2520
Georg Brandl2134e752007-05-21 20:34:16 +00002521- Patch #1686487: you can now pass any mapping after '**' in function
2522 calls.
2523
Collin Winter62903052007-05-18 23:11:24 +00002524- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002525 "except E as target:". This is to provide forwards compatibility
2526 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002527
Brett Cannon229cee22007-05-05 01:34:02 +00002528- Deprecate BaseException.message as per PEP 352.
2529
Georg Brandl3ee81df2008-05-17 18:14:43 +00002530- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002531 inherited from a builtin base.
2532
Vinay Sajip8549ce32007-05-06 17:53:37 +00002533- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002534 setting a plain string, ie don't expand to single letter identifiers.
2535
Raymond Hettinger13936692007-04-11 18:40:58 +00002536- Request #1191699: Slices can now be pickled.
2537
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002538- Request #1193128: str.translate() now allows a None argument for
2539 translations that only remove characters without re-mapping the
2540 remaining characters.
2541
Georg Brandl5cb76c12007-03-21 09:00:39 +00002542- Patch #1682205: a TypeError while unpacking an iterable is no longer
2543 masked by a generic one with the message "unpack non-sequence".
2544
Neal Norwitzaa754b72007-03-21 06:39:48 +00002545- Remove unused file Python/fmod.c.
2546
Guido van Rossum143b5642007-03-23 04:58:42 +00002547- Bug #1683368: The object.__init__() and object.__new__() methods are
2548 now stricter in rejecting excess arguments. The only time when
2549 either allows excess arguments is when it is not overridden and the
2550 other one is. For backwards compatibility, when both are
2551 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002552 warning later). Also, type.__init__() insists on the same signature
2553 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002554
Georg Brandl3ee81df2008-05-17 18:14:43 +00002555- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2556 object to complex using its __complex__() method before falling back
2557 to the __float__() method. Therefore, the functions in the cmath
2558 module now can operate on objects that define a __complex__()
2559 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002560
Georg Brandl3ee81df2008-05-17 18:14:43 +00002561- Patch #1623563: allow __class__ assignment for classes with
2562 __slots__. The old and the new class are still required to have the
2563 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002564
Georg Brandl3ee81df2008-05-17 18:14:43 +00002565- Patch #1642547: Fix an error/crash when encountering syntax errors
2566 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002568- Patch #1462488: Python no longer segfaults when
2569 ``object.__reduce_ex__()`` is called with an object that is faking
2570 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002571
Georg Brandl3ee81df2008-05-17 18:14:43 +00002572- Patch #1680015: Don't modify __slots__ tuple if it contains an
2573 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00002575- Patch #1444529: the builtin compile() now accepts keyword arguments.
2576
Georg Brandl7b9c5552007-03-12 14:30:05 +00002577- Bug #1678647: write a newline after printing an exception in any
2578 case, even when converting the value to a string failed.
2579
Georg Brandl871f1bc2007-03-12 13:17:36 +00002580- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002581 its argument, if it exists. If not, it will work like before. This
2582 allows customizing the output of dir() in the presence of a
2583 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002584
Collin Winter276887b2007-03-12 16:11:39 +00002585- Patch #922167: Python no longer segfaults when faced with infinitely
2586 self-recursive reload() calls (as reported by bug #742342).
2587
Georg Brandl3ee81df2008-05-17 18:14:43 +00002588- Patch #1675981: remove unreachable code from ``type.__new__()``
2589 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002591- Patch #1491866: change the complex() constructor to allow
2592 parthensized forms. This means complex(repr(x)) now works instead of
2593 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002594
Georg Brandlaa2321b2007-03-07 00:40:28 +00002595- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002596 makes the filenames the warning module prints much more sensible
2597 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002598
Georg Brandl49aafc92007-03-07 00:34:46 +00002599- Variant of patch #697613: don't exit the interpreter on a SystemExit
2600 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002601 variable is given, but break into the interactive interpreter just
2602 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00002603
Georg Brandl3ee81df2008-05-17 18:14:43 +00002604- Patch #1638879: don't accept strings with embedded NUL bytes in

Georg Brandl3ee81df2008-05-17 18:14:43 +00002607- Bug #1674503: close the file opened by execfile() in an error
2608 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00002609
Georg Brandl0fca97a2007-03-05 22:28:08 +00002610- Patch #1674228: when assigning a slice (old-style), check for the

3103 (as opposed to the command line) will now write file names ending in
3104 ".cpp" too.
3105
Facundo Batistad918a652007-04-24 13:54:38 +00003106- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003107 the client's request was successfully received, understood, and
3108 accepted. Now in these cases no error is raised in urllib (issue
3109 #1177) and urllib2.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003117- Added a timeout parameter to the constructor of other protocols
3118 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3119 work started with create_connection() and timeout in httplib, and
3120 closes patch #723312.
3121
Vinay Sajip8549ce32007-05-06 17:53:37 +00003122- Patch #1676823: Added create_connection() to socket.py, which may be
3123 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003124 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003125
Martin v. Löwis0af33882007-03-23 13:27:15 +00003126- Bug #978833: Revert r50844, as it broke _socketobject.dup.

3146
Georg Brandlf66b6032007-03-14 08:27:52 +00003147- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003148 AttributeError instead of an IOError when the server's response
3149 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003150

Georg Brandl3ee81df2008-05-17 18:14:43 +00003155- Patch #1429539: pdb now correctly initializes the __main__ module
3156 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003157 correctly now.
3158

3165
Georg Brandl3ee81df2008-05-17 18:14:43 +00003166- Patch #1530482: add pydoc.render_doc() which returns the
3167 documentation for a thing instead of paging it to stdout, which

Georg Brandl9e6b4702007-03-13 18:15:41 +00003179- Patch #1581073: add a flag to textwrap that prevents the dropping of
3180 whitespace while wrapping.
3181
Georg Brandl92a6bae2007-03-13 17:43:32 +00003182- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003183 are set for invalid interpolation sequences that would lead to
3184 errors on reading back those values.

3227 returned string up to the first NUL character.

3238
Georg Brandl3ee81df2008-05-17 18:14:43 +00003239- unittest now verifies more of its assumptions. In particular,
3240 TestCase and TestSuite subclasses (not instances) are no longer
3241 accepted in TestSuite.addTest(). This should cause no
3242 incompatibility since it never made sense with ordinary subclasses
3243 -- the failure just occurred later, with a more cumbersome
3244 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00003245

3253 given a unicode argument and os.listdir() returns unicode filenames.
3254
Georg Brandl3ee81df2008-05-17 18:14:43 +00003255- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00003633 time so that opening a database previously created with the DB_DUP
3634 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3635 opens. Specifically: dictionary assignment to a DB object will
3636 replace all values for a given key when the database allows
3637 duplicate values. DB users should use DB.put(k, v) when they want
3638 to store duplicates; not DB[k] = v.

3645 characters with ASCII value less than 32. Also, it correctly quotes
3646 dots only if they occur on a single line, as opposed to the previous
3647 behavior of quoting dots if they are the second character of any
3648 line.
