377 an existing .py counterpart, override the co_filename attributes of all
378 code objects if the original filename is obsolete (which can happen if the
379 file has been renamed, moved, or if it is accessed through different paths).
380 Patch by Ziga Seilnacht and Jean-Paul Calderone.

Georg Brandl734373c2009-01-03 21:55:17 +0000382- Issue #4075: Use OutputDebugStringW in Py_FatalError.

416
Vinay Sajip6badbe92009-01-20 22:49:13 +0000417- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +0000418 method on file objects with closefd=False. The file descriptor is still
419 kept open but the file object behaves like a closed file. The ``FileIO``
420 object also got a new readonly attribute ``closefd``.
421
Georg Brandlfa71a902008-12-05 09:08:28 +0000422- Issue #3689: The list reversed iterator now supports __length_hint__

627- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
628 302 conformant loader) will now work correctly in most cases (they
629 are still subject to the constraints that exist for all code running
630 from inside a module loaded via a PEP 302 loader and attempting to

789What's New in Python 2.6.1
790==========================
791
792*Release date: 04-Dec-2008*
793
794Core and Builtins
795-----------------
796
797- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
798 interpreter to abort ("Fatal Python error: Could not reset the stack!")
799 instead of throwing a MemoryError.
800
801- Issue #4367: Python would segfault during compiling when the unicodedata
802 module couldn't be imported and \N escapes were present.
803
804- Issue #4348: Some bytearray methods returned that didn't cause any change to
805 the bytearray, returned the same bytearray instead of a copy.
806
807- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
808
809- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
810
811- Issue #4048: The parser module now correctly validates relative imports.
812
813- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
814 exec statement.
815
816- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
817 method does not return iterators for the 4th and 5th items.
818
819- Issue #4209: Enabling unicode_literals and the print_function in the same
820 __future__ import didn't work.
821
822- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
823 returned a path longer than MAX_PATH. (But It's doubtful this code path is
824 really executed because I cannot move to such directory on win2k)
825
826- Issue #4069: When set.remove(element) is used with a set element, the element
827 is temporarily replaced with an equivalent frozenset. But the eventual
828 KeyError would always report the empty frozenset([]) as the missing key. Now
829 it correctly refers to the initial element.
830
831- Fixed C99 style comments in several files. Python is now C89 compatible
832 again.

982 PyString_FromFormat or PyErr_Format to display size_t values. The macro
983 PY_FORMAT_SIZE_T is designed to select the correct format for the OS

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001002- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001003 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001004 was correctly parsed but parsing of subsequent arguments failed.
1005
Vinay Sajip35e3b032008-09-01 14:33:59 +00001006- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001007 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1008 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1009 when given a tuple of classes as second argument, were looking up
1010 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1011 type object.
1012
Neal Norwitz18aa3882008-08-24 05:04:52 +00001013- Fix crashes on memory allocation failure found with failmalloc.

1082 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1083 for catch_warnings() also led to an improvement in the raising of a
1084 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001106- Issue #2975: When compiling several extension modules with Visual Studio 2008
1107 from the same python interpreter, some environment variables would grow
1108 without limit.
1109

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001147What's New in Python 2.6 beta 3?
1148================================
1149
Barry Warsaw07a4a382008-08-21 01:15:08 +00001150*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001151
1152Core and Builtins
1153-----------------
1154
Guido van Rossumf8402962008-08-20 15:01:50 +00001155- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1156 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1157 extensions do not automatically benefit from the class attribute
1158 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1159 to their tp_flags field if they care. This is a backwards
1160 compatibility feature; in 3.0, all types will use the cache by
1161 default.
1162
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001163- Keyword arguments can now follow starred arguments. (``f(a, *args,
1164 keyword=23)`` is now valid syntax.)
1165
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001166- ctypes function pointers that are COM methods have a boolean True
1167 value again.
1168
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001169- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1170 by denying s# to parse objects that have a releasebuffer procedure,
1171 and introducing s*.
1172
Georg Brandl1e13ea92008-08-11 09:07:59 +00001173- Issue #3537: Fix an assertion failure when an empty but presized dict
1174 object was stored in the freelist.
1175
Mark Dickinsonb6467572008-08-04 21:30:09 +00001176- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1177 ValueError consistently across platforms.
1178
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001179- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1180 (64bit Unix, for example), unichr() would truncate its argument and return
1181 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1182
Neal Norwitze7d8be82008-07-31 17:17:14 +00001183- Apply security patches from Apple.
1184
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001185- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1186 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1187
Antoine Pitrou92f82162008-07-25 22:22:08 +00001188- Issue #1819: function calls with several named parameters are now on
1189 average 35% faster (as measured by pybench).
1190
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001191- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1192 the python debugger steps into a class statement: the free variables (local
1193 variables defined in an outer scope) would be deleted from the outer scope.
1194
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001195- Issue #2620: Overflow checking when allocating or reallocating memory
1196 was not always being done properly in some python types and extension
1197 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1198 all been updated to perform better checks and places in the code that
1199 would previously leak memory on the error path when such an allocation
1200 failed have been fixed.

1204
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001205- Issue #3612: Added some missing basic types in ctypes.wintypes.
1206
Benjamin Petersone977ad42008-08-20 01:42:01 +00001207- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1208 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1209
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001210- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1211 version reported by these tools does not necessarily follow the python
1212 version numbering scheme, so the module is less strict when parsing it.
1213
Nick Coghlanf70385a2008-08-18 12:42:46 +00001214- Issue #2235: Added Py3k warnings for types which will become unhashable
1215 under the stricter __hash__ inheritance rules in 3.0. Several types
1216 which did not meet the rules for hash invariants and were already
1217 unhashable in 3.0 have now been explicitly flagged as unhashable in
1218 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1219 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1220
Brett Cannon88f801d2008-08-18 00:46:22 +00001221- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1222 imported into the module but exposed as part of the module's API.
1223
Brett Cannon7b96f072008-08-18 00:41:11 +00001224- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1225
Brett Cannon46225e72008-08-18 00:36:52 +00001226- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1227
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001228- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1229
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001230- Issue #3575: Incremental decoder's decode function now takes bytearray
1231 by using 's*' instead of 't#'.
1232
Jesus Cea585ad8a2009-07-02 15:37:21 +00001233- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001234 fails unicode conversion on 2nd parameter. (windows only)
1235
Facundo Batista94f243a2008-08-17 03:38:39 +00001236- Issue 2464. urllib2 now supports a malformation in the URL received
1237 in a redirect.
1238
Brett Cannonabe423e2008-08-16 21:47:07 +00001239- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001240 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001241
Facundo Batistaeb90b782008-08-16 14:44:07 +00001242- Issue #2776: fixed small issue when handling an URL with double slash
1243 after a 302 response in the case of not going through a proxy.
1244
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001245- Issue #2676: in the email package, content-type parsing was hanging on
1246 pathological input because of quadratic or exponential behaviour of a
1247 regular expression.
1248
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001249- Issue #3476: binary buffered reading through the new "io" library is now
1250 thread-safe.
1251
Brett Cannonbf3157b2008-08-14 05:00:03 +00001252- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1253 since mimetools itself is deprecated. Because modules are cached, all
1254 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1255
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001256- Issue #3134: shutil referenced undefined WindowsError symbol.
1257
Robert Schuppenies14646332008-08-10 11:01:53 +00001258- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1259 menu entries were not deleted.
1260
Brett Cannon83e81842008-08-09 23:30:55 +00001261- Copied the implementation of reduce() to _functools.reduce() to have a
1262 version that did not raise a DeprecationWarning under -3.
1263
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001264- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1265 a MemoryError rather than silently stop the iteration.
1266
Guido van Rossum59ce9012008-08-09 14:55:34 +00001267- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1268 to _sre.compile() will now be rejected. This should not affect anybody
1269 since the re.compile() function never generates invalid re-bytecode.
1270
Skip Montanaroa032bf42008-08-08 22:52:51 +00001271- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1272 upon first access it can be automatically initialized from the csv file if
1273 it wasn't initialized during instantiation.
1274
Brett Cannon3aa2a492008-08-06 22:28:09 +00001275- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1276 the reload() built-in has been removed.
1277
Brett Cannon7e30b672008-08-04 21:52:25 +00001278- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001279 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001290 asking for a specific length. This problem only affected files opened

1343
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001344*Release date: 17-Jul-2008*

1347-----------------
1348
Georg Brandl3e483f62008-07-16 22:57:41 +00001349- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1350 its methods now allow for items objects that can be converted to
1351 an integer using operator.index().
1352
Mark Dickinson64b7e502008-07-16 09:40:03 +00001353- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1354 produced a ValueError instead of giving the correct float.
1355
Eric Smitha5fa5a22008-07-16 00:11:49 +00001356- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1357 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1358
Mark Dickinson7103aa42008-07-15 19:08:33 +00001359- Issue #3008: the float type has a new instance method 'float.hex'
1360 and a new class method 'float.fromhex' to convert floating-point
1361 numbers to and from hexadecimal strings, respectively.
1362
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001363- Issue #2235: __hash__ is once again inherited by default. To allow
1364 collections.Hashable to remain meaningful in the presence of the
1365 default hash implementation (object.__hash__), it is now possible
1366 to explicit block inheritance of hash by setting __hash__=None at
1367 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1368 level.
1369
Nick Coghlanb028f502008-07-13 14:52:36 +00001370- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1371 the parent module cannot be found while performing an absolute import.
1372 This means that an incorrectly defined __package__ attribute will
1373 now only prevent relative imports in that module rather than causing
1374 all imports from that module to fail.
1375
Nick Coghlan14ff9942008-07-08 14:21:42 +00001376- Issue #2517: Allow unicode messages in Exceptions again by correctly

1386 another thread's dictionary.
1387
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001388- Issue #3004: Minor change to slice.indices(): the start and stop
1389 arguments are now treated identically, making the behaviour easier
1390 to describe and understand. For example, slice(None, -10,
1391 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1392 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1393 10, -1).
1394
Georg Brandl278fc502008-07-19 12:46:12 +00001395- Issue #3219: Calling a function with repeated keyword arguments,
1396 f(a=2, a=23), would not cause a syntax error. This was a regression
1397 from 2.4 caused by the switch to the new compiler.

1400 other freelists. Changes their CompactFreeList apis into

1408 error when they failed.
1409
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001410- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001435- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1436 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001437 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001438 content-length. The problem had been corrected in the 2.4 branch, but never
1439 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001454- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl3ee81df2008-05-17 18:14:43 +00001909- Issue #1631171: Re-implement the 'warnings' module in C (the
1910 original Python code has been kept as backup). This will allow for
1911 using the 'warning's machinery in such places as the parser where
1912 use of pure Python code is not possible. Both the ``showarning()``
1913 and ``formatwarning()`` gain an optional 'line' argument which is
1914 not called by default for backwards-compatibility reasons. Setting
1915 ``warnings.showwarning()`` to an implementation that lacks support
1916 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001941- The getpass module has been improved on Unix. It now uses /dev/tty
1942 by default and uses stderr instead of stdout. A GetPassWarning is
1943 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001958- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001959 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00001979- Issue #2550: The approach used by client/server code for obtaining
1980 ports to listen on in network-oriented tests has been refined in an
1981 effort to facilitate running multiple instances of the entire
1982 regression test suite in parallel without issue.
1983 test_support.bind_port() has been fixed such that it will always
1984 return a unique port -- which wasn't always the case with the
1985 previous implementation, especially if socket options had been set
1986 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1987 new implementation of bind_port() will actually raise an exception
1988 if it is passed an AF_INET/SOCK_STREAM socket with either the
1989 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1990 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1991 the socket it's been passed. This currently only applies to
1992 Windows. This option prevents any other sockets from binding to the
1993 host/port we've bound to, thus removing the possibility of the
1994 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1995 when a second SOCK_STREAM socket binds and accepts to a host/port
1996 that's already been bound by another socket. The optional preferred
1997 port parameter to bind_port() has been removed. Under no
1998 circumstances should tests be hard coding ports!
1999
2000 test_support.find_unused_port() has also been introduced, which will
2001 pass a temporary socket object to bind_port() in order to obtain an
2002 unused port. The temporary socket object is then closed and
2003 deleted, and the port is returned. This method should only be used
2004 for obtaining an unused port in order to pass to an external program
2005 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2006 a parameter to a server-oriented class that doesn't give you direct
2007 access to the underlying socket used.
2008
2009 Finally, test_support.HOST has been introduced, which should be used
2010 for the host argument of any relevant socket calls (i.e. bind and
2011 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002012
2013 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002014 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002015 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2016 test_asynchat and test_socket_ssl.
2017
Georg Brandl3ee81df2008-05-17 18:14:43 +00002018 It is now possible for multiple instances of the regression test
2019 suite to run in parallel without issue.

2286-----------------
2287
Fred Drakea8ee94b2008-03-01 02:45:07 +00002288- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002289 644. The mode is now inherited from the py file.

2292
2293- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002294
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002295- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002296 issue 215555 for a discussion.
2297
Eric Smitha73fbe72008-02-23 03:09:44 +00002298- Added the future_builtins module, which contains hex() and oct().
2299 These are the PEP 3127 version of these functions, designed to be
2300 compatible with the hex() and oct() builtins from Python 3.0. They
2301 differ slightly in their output formats from the existing, unchanged
2302 Python 2.6 builtins. The expected usage of the future_builtins
2303 module is:
2304 from future_builtins import hex, oct
2305
Eric Smith7ef40bf2008-02-20 23:34:22 +00002306- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2307 exponents for exponents with absolute value < 100. Follows C99
2308 standard. This is a change on Windows, which would use 3 digits.
2309 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2310 so that any alterations it does to the resulting string will be
2311 available in stringlib/formatter.h (for float.__format__).
2312
Eric Smith5a3c1352008-02-19 13:21:56 +00002313- Implemented PEP 3101, Advanced String Formatting. This adds a new
2314 builtin format(); a format() method for str and unicode; a
2315 __format__() method to object, str, unicode, int, long, float, and
2316 datetime; the class string.Formatter; and the C API
2317 PyObject_Format().
2318
Georg Brandl3ee81df2008-05-17 18:14:43 +00002319- Fixed several potential crashes, all caused by specially crafted
2320 __del__ methods exploiting objects in temporarily inconsistent
2321 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002322
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002323- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002324 prevent a possible crash: an Abstract Base Class would try to access
2325 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002326

Georg Brandl3ee81df2008-05-17 18:14:43 +00002330- Clear all free lists during a gc.collect() of the highest generation
2331 in order to allow pymalloc to free more arenas. Python may give back
2332 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002333
Georg Brandl3ee81df2008-05-17 18:14:43 +00002334- Issue #2045: Fix an infinite recursion triggered when printing a
2335 subclass of collections.defaultdict, if its default_factory is set
2336 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002337
Christian Heimesf75dbef2008-02-08 00:11:31 +00002338- Fixed a minor memory leak in dictobject.c. The content of the free
2339 list was not freed on interpreter shutdown.
2340
Georg Brandl3ee81df2008-05-17 18:14:43 +00002341- Limit free list of method and builtin function objects to 256
2342 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002344- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2345 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002346 to compact the internal free lists of pre-allocted ints and floats.
2347
Georg Brandl3ee81df2008-05-17 18:14:43 +00002348- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2349 calls. Python expected the return type int but the fork familie
2350 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002351
Georg Brandl3ee81df2008-05-17 18:14:43 +00002352- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00002364- Patch #1473257: generator objects gain a gi_code attribute. This is
2365 the same object as the func_code attribute of the function that
2366 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002367
Georg Brandl3ee81df2008-05-17 18:14:43 +00002368- Issue #1920: "while 0" statements were completely removed by the
2369 compiler, even in the presence of an "else" clause, which is
2370 supposed to be run when the condition is false. Now the compiler

Guido van Rossumeead05f2008-01-24 18:21:02 +00002373- A few crashers fixed: weakref_in_del.py (issue #1377858);
2374 loosing_dict_ref.py (issue #1303614, test67.py);
2375 borrowed_ref_[34].py (not in tracker).
2376
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002377- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002378 suppressed while an extension is loaded by calling SetErrorMode in
2379 dynload_win.c. The error is still reported properly.
2380
Georg Brandl3ee81df2008-05-17 18:14:43 +00002381- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002382 several extension methods and modules do not work without unicode
2383 support.
2384
Georg Brandl26543b12008-01-21 18:36:51 +00002385- Issue #1882: when compiling code from a string, encoding cookies in the
2386 second line of code were not always recognized correctly.
2387
Georg Brandl14404b62008-01-19 19:27:05 +00002388- Issue #1679: "0x" was taken as a valid integer literal.
2389
Georg Brandl6caad7d2008-01-26 14:19:22 +00002390- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002391 added.
2392
Christian Heimesc94e2b52008-01-14 04:13:37 +00002393- sys.float_info / PyFloat_GetInfo: The floating point information
2394 object was converted from a dict to a specialized structseq object.
2395
Georg Brandl3ee81df2008-05-17 18:14:43 +00002396- Patch #1816: Added sys.flags structseq. It exposes the status of
2397 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002398
Georg Brandl3ee81df2008-05-17 18:14:43 +00002399- Objects/structseq.c: Implemented new structseq representation. The
2400 patch makes structseqs (e.g. the return value of os.stat) more
2401 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002402
Georg Brandl3ee81df2008-05-17 18:14:43 +00002403- Patch #1700288: added a type attribute cache that caches method
2404 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002405
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002406- Bug #1776: __import__() no longer accepts filenames on any platform.
2407 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002408
Georg Brandlaed6c662008-01-07 17:25:53 +00002409- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2410
Georg Brandl3ee81df2008-05-17 18:14:43 +00002411- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2412 envvar and sys.dont_write_bytecode attribute. All these can be set
2413 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002414
Georg Brandl3ee81df2008-05-17 18:14:43 +00002415- Improve some exception messages when Windows fails to load an
2416 extension module. Now we get for example '%1 is not a valid Win32
2417 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002418
Georg Brandl3ee81df2008-05-17 18:14:43 +00002419- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002421- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2422 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002423
Christian Heimes0a8143f2007-12-18 23:22:54 +00002424- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002425 and INF. float("nan"), float("inf") and float("-inf") now work on
2426 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002427
Georg Brandl3ee81df2008-05-17 18:14:43 +00002428- Compiler now generates simpler and faster code for dictionary
2429 literals. The oparg for BUILD_MAP now indicates an estimated
2430 dictionary size. There is a new opcode, STORE_MAP, for adding
2431 entries to the dictionary.

2449 running, and if the deallocation of its frames somehow calls the
2450 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002451

2456
Georg Brandl3ee81df2008-05-17 18:14:43 +00002457- Issue #1460: The utf-7 incremental decoder did not accept truncated
2458 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002459
Georg Brandl3ee81df2008-05-17 18:14:43 +00002460- Patch #1739468: Directories and zipfiles containing a __main__.py
2461 file can now be directly executed by passing their name to the
2462 interpreter. The directory/zipfile is automatically inserted as the
2463 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002464
Georg Brandl3ee81df2008-05-17 18:14:43 +00002465- Issue #1265: Fix a problem with sys.settrace, if the tracing
2466 function uses a generator expression when at the same time the
2467 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002468
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002469- sets and frozensets now have an isdisjoint() method.
2470
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002471- optimize the performance of builtin.sum().
2472
Neal Norwitz44f326e2007-10-05 05:29:17 +00002473- Fix warnings found by the new version of the Coverity checker.
2474
Georg Brandl3ee81df2008-05-17 18:14:43 +00002475- The enumerate() builtin function is no longer bounded to sequences
2476 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2477 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002478
Georg Brandl3ee81df2008-05-17 18:14:43 +00002479- Issue #1686386: Tuple's tp_repr did not take into account the
2480 possibility of having a self-referential tuple, which is possible
2481 from C code. Nor did object's tp_str consider that a type's tp_str
2482 could do something that could lead to an inifinite recursion.
2483 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2484 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002485
Georg Brandl3ee81df2008-05-17 18:14:43 +00002486- Issue #1164: It was possible to trigger deadlock when using the
2487 'print' statement to write to a file since the GIL was not released
2488 as needed. Now PyObject_Print() does the right thing along with
2489 various tp_print implementations of the built-in types and those in
2490 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002491
Georg Brandl3ee81df2008-05-17 18:14:43 +00002492- Issue #1147: Exceptions were directly allowing string exceptions in
2493 their throw() method even though string exceptions no longer
2494 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002495
Georg Brandl3ee81df2008-05-17 18:14:43 +00002496- Issue #1096: Prevent a segfault from getting the repr of a very
2497 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002498
Brett Cannon1e534b52007-09-07 04:18:30 +00002499- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002500 PyObject_Call() never calling back out to Python code to trigger
2501 recursion depth updates/checks. Required the creation of a static
2502 RuntimeError instance in case normalizing an exception put the
2503 recursion check value past its limit. Fixes crashers
2504 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002505
Georg Brandl3ee81df2008-05-17 18:14:43 +00002506- Patch #1031213: Decode source line in SyntaxErrors back to its

2510 with %G.
2511
Georg Brandl3ee81df2008-05-17 18:14:43 +00002512- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00002519- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002520 __*__ attributes. (Some already existed, e.g., __doc__ and
2521 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002522
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002523- Add -3 option to the interpreter to warn about features that are
2524 deprecated and will be changed/removed in Python 3.0.
2525
Georg Brandl2134e752007-05-21 20:34:16 +00002526- Patch #1686487: you can now pass any mapping after '**' in function
2527 calls.
2528
Collin Winter62903052007-05-18 23:11:24 +00002529- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002530 "except E as target:". This is to provide forwards compatibility
2531 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002532
Brett Cannon229cee22007-05-05 01:34:02 +00002533- Deprecate BaseException.message as per PEP 352.
2534
Georg Brandl3ee81df2008-05-17 18:14:43 +00002535- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002536 inherited from a builtin base.
2537
Vinay Sajip8549ce32007-05-06 17:53:37 +00002538- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002539 setting a plain string, ie don't expand to single letter identifiers.
2540
Raymond Hettinger13936692007-04-11 18:40:58 +00002541- Request #1191699: Slices can now be pickled.
2542
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002543- Request #1193128: str.translate() now allows a None argument for
2544 translations that only remove characters without re-mapping the
2545 remaining characters.
2546
Georg Brandl5cb76c12007-03-21 09:00:39 +00002547- Patch #1682205: a TypeError while unpacking an iterable is no longer
2548 masked by a generic one with the message "unpack non-sequence".
2549
Neal Norwitzaa754b72007-03-21 06:39:48 +00002550- Remove unused file Python/fmod.c.
2551
Guido van Rossum143b5642007-03-23 04:58:42 +00002552- Bug #1683368: The object.__init__() and object.__new__() methods are
2553 now stricter in rejecting excess arguments. The only time when
2554 either allows excess arguments is when it is not overridden and the
2555 other one is. For backwards compatibility, when both are
2556 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002557 warning later). Also, type.__init__() insists on the same signature
2558 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002559
Georg Brandl3ee81df2008-05-17 18:14:43 +00002560- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2561 object to complex using its __complex__() method before falling back
2562 to the __float__() method. Therefore, the functions in the cmath
2563 module now can operate on objects that define a __complex__()
2564 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002565
Georg Brandl3ee81df2008-05-17 18:14:43 +00002566- Patch #1623563: allow __class__ assignment for classes with
2567 __slots__. The old and the new class are still required to have the
2568 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002569
Georg Brandl3ee81df2008-05-17 18:14:43 +00002570- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002573- Patch #1462488: Python no longer segfaults when
2574 ``object.__reduce_ex__()`` is called with an object that is faking
2575 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002576
Georg Brandl3ee81df2008-05-17 18:14:43 +00002577- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002580- Patch #1444529: the builtin compile() now accepts keyword arguments.
2581
Georg Brandl7b9c5552007-03-12 14:30:05 +00002582- Bug #1678647: write a newline after printing an exception in any
2583 case, even when converting the value to a string failed.
2584
Georg Brandl871f1bc2007-03-12 13:17:36 +00002585- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002586 its argument, if it exists. If not, it will work like before. This
2587 allows customizing the output of dir() in the presence of a
2588 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002589
Collin Winter276887b2007-03-12 16:11:39 +00002590- Patch #922167: Python no longer segfaults when faced with infinitely
2591 self-recursive reload() calls (as reported by bug #742342).
2592
Georg Brandl3ee81df2008-05-17 18:14:43 +00002593- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002596- Patch #1491866: change the complex() constructor to allow
2597 parthensized forms. This means complex(repr(x)) now works instead of
2598 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002599
Georg Brandlaa2321b2007-03-07 00:40:28 +00002600- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002601 makes the filenames the warning module prints much more sensible
2602 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002603
Georg Brandl49aafc92007-03-07 00:34:46 +00002604- Variant of patch #697613: don't exit the interpreter on a SystemExit
2605 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002606 variable is given, but break into the interactive interpreter just
2607 like on other exceptions or normal program exit.

3106
Georg Brandlfb4b3b72007-04-24 15:27:13 +00003107- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
3108 (as opposed to the command line) will now write file names ending in
3109 ".cpp" too.
3110
Facundo Batistad918a652007-04-24 13:54:38 +00003111- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003112 the client's request was successfully received, understood, and
3113 accepted. Now in these cases no error is raised in urllib (issue
3114 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00003115

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003122- Added a timeout parameter to the constructor of other protocols
3123 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3124 work started with create_connection() and timeout in httplib, and
3125 closes patch #723312.
3126
Vinay Sajip8549ce32007-05-06 17:53:37 +00003127- Patch #1676823: Added create_connection() to socket.py, which may be
3128 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003129 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003130
Martin v. Löwis0af33882007-03-23 13:27:15 +00003131- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003138- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
3139 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00003140 directories.
3141

3151
Georg Brandlf66b6032007-03-14 08:27:52 +00003152- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003153 AttributeError instead of an IOError when the server's response
3154 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003155
Georg Brandl3ee81df2008-05-17 18:14:43 +00003156- Patch #957650: "%var%" environment variable references are now
3157 properly expanded in ntpath.expandvars(), also "~user" home
3158 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00003159
Georg Brandl3ee81df2008-05-17 18:14:43 +00003160- Patch #1429539: pdb now correctly initializes the __main__ module
3161 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003162 correctly now.
3163
Georg Brandlbad6f192007-03-13 21:32:56 +00003164- The nonobvious commands.getstatus() function is now deprecated.

3170
Georg Brandl3ee81df2008-05-17 18:14:43 +00003171- Patch #1530482: add pydoc.render_doc() which returns the
3172 documentation for a thing instead of paging it to stdout, which
3173 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00003174
Georg Brandl3ee81df2008-05-17 18:14:43 +00003175- Patch #1533909: the timeit module now accepts callables in addition

3181 parameter which can be set to False to prevent the default
3182 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00003183
Georg Brandl9e6b4702007-03-13 18:15:41 +00003184- Patch #1581073: add a flag to textwrap that prevents the dropping of
3185 whitespace while wrapping.
3186
Georg Brandl92a6bae2007-03-13 17:43:32 +00003187- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003188 are set for invalid interpolation sequences that would lead to
3189 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00003190

3203
Georg Brandl94fe3f52007-03-13 09:32:11 +00003204- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00003205 field names in its exception message if you try to write a record
3206 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00003224

3232 returned string up to the first NUL character.
3233

3243
Georg Brandl3ee81df2008-05-17 18:14:43 +00003244- unittest now verifies more of its assumptions. In particular,
3245 TestCase and TestSuite subclasses (not instances) are no longer
3246 accepted in TestSuite.addTest(). This should cause no
3247 incompatibility since it never made sense with ordinary subclasses
3248 -- the failure just occurred later, with a more cumbersome
3249 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00003250

3258 given a unicode argument and os.listdir() returns unicode filenames.
3259
Georg Brandl3ee81df2008-05-17 18:14:43 +00003260- Patch #1673619: setup.py identifies extension modules it doesn't
3261 know how to build and those it knows how to build but that fail to
3262 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003638 time so that opening a database previously created with the DB_DUP
3639 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3640 opens. Specifically: dictionary assignment to a DB object will
3641 replace all values for a given key when the database allows
3642 duplicate values. DB users should use DB.put(k, v) when they want
3643 to store duplicates; not DB[k] = v.

3650 characters with ASCII value less than 32. Also, it correctly quotes
3651 dots only if they occur on a single line, as opposed to the previous
3652 behavior of quoting dots if they are the second character of any
3653 line.
