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392 code objects if the original filename is obsolete (which can happen if the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

430
Vinay Sajip6badbe92009-01-20 22:49:13 +0000431- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +0000432 method on file objects with closefd=False. The file descriptor is still
433 kept open but the file object behaves like a closed file. The ``FileIO``
434 object also got a new readonly attribute ``closefd``.
435
Georg Brandlfa71a902008-12-05 09:08:28 +0000436- Issue #3689: The list reversed iterator now supports __length_hint__

803What's New in Python 2.6.1
804==========================
805
806*Release date: 04-Dec-2008*
807
808Core and Builtins
809-----------------
810
811- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
812 interpreter to abort ("Fatal Python error: Could not reset the stack!")
813 instead of throwing a MemoryError.
814
815- Issue #4367: Python would segfault during compiling when the unicodedata
816 module couldn't be imported and \N escapes were present.
817
818- Issue #4348: Some bytearray methods returned that didn't cause any change to
819 the bytearray, returned the same bytearray instead of a copy.
820
821- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
822
823- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
824
825- Issue #4048: The parser module now correctly validates relative imports.
826
827- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
828 exec statement.
829
830- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
831 method does not return iterators for the 4th and 5th items.
832
833- Issue #4209: Enabling unicode_literals and the print_function in the same
834 __future__ import didn't work.
835
836- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
837 returned a path longer than MAX_PATH. (But It's doubtful this code path is
838 really executed because I cannot move to such directory on win2k)
839
840- Issue #4069: When set.remove(element) is used with a set element, the element
841 is temporarily replaced with an equivalent frozenset. But the eventual
842 KeyError would always report the empty frozenset([]) as the missing key. Now
843 it correctly refers to the initial element.
844
845- Fixed C99 style comments in several files. Python is now C89 compatible
846 again.

1005
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001006- Issue #3777: long() applied to a float object now always return a long
1007 object; previously an int would be returned for small values. the __long__
1008 method is allowed to return either an int or a long, but the behaviour of
1009 float objects should not change to respect backward compatibility.
1010
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001011- Issue #3751: str.rpartition would perform a left-partition when called with
1012 a unicode argument.
1013
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001014- Issue #3683: Fix compilation when --without-threads is given.
1015
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001016- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001017 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001018 was correctly parsed but parsing of subsequent arguments failed.
1019
Vinay Sajip35e3b032008-09-01 14:33:59 +00001020- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001021 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1022 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1023 when given a tuple of classes as second argument, were looking up
1024 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1025 type object.
1026
Neal Norwitz18aa3882008-08-24 05:04:52 +00001027- Fix crashes on memory allocation failure found with failmalloc.

1096 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1097 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001161What's New in Python 2.6 beta 3?
1162================================
1163
Barry Warsaw07a4a382008-08-21 01:15:08 +00001164*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001165
1166Core and Builtins
1167-----------------
1168
Guido van Rossumf8402962008-08-20 15:01:50 +00001169- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1170 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1171 extensions do not automatically benefit from the class attribute
1172 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1173 to their tp_flags field if they care. This is a backwards
1174 compatibility feature; in 3.0, all types will use the cache by
1175 default.
1176
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001177- Keyword arguments can now follow starred arguments. (``f(a, *args,
1178 keyword=23)`` is now valid syntax.)
1179
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001180- ctypes function pointers that are COM methods have a boolean True
1181 value again.
1182
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001183- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1184 by denying s# to parse objects that have a releasebuffer procedure,
1185 and introducing s*.
1186
Georg Brandl1e13ea92008-08-11 09:07:59 +00001187- Issue #3537: Fix an assertion failure when an empty but presized dict
1188 object was stored in the freelist.
1189
Mark Dickinsonb6467572008-08-04 21:30:09 +00001190- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1191 ValueError consistently across platforms.
1192
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001193- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1194 (64bit Unix, for example), unichr() would truncate its argument and return
1195 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1196
Neal Norwitze7d8be82008-07-31 17:17:14 +00001197- Apply security patches from Apple.
1198
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001199- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1200 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1201
Antoine Pitrou92f82162008-07-25 22:22:08 +00001202- Issue #1819: function calls with several named parameters are now on
1203 average 35% faster (as measured by pybench).
1204
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001205- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1206 the python debugger steps into a class statement: the free variables (local
1207 variables defined in an outer scope) would be deleted from the outer scope.
1208
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001209- Issue #2620: Overflow checking when allocating or reallocating memory
1210 was not always being done properly in some python types and extension
1211 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1212 all been updated to perform better checks and places in the code that
1213 would previously leak memory on the error path when such an allocation
1214 failed have been fixed.

1218
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001219- Issue #3612: Added some missing basic types in ctypes.wintypes.
1220
Benjamin Petersone977ad42008-08-20 01:42:01 +00001221- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1222 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1223
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001224- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1225 version reported by these tools does not necessarily follow the python
1226 version numbering scheme, so the module is less strict when parsing it.
1227
Nick Coghlanf70385a2008-08-18 12:42:46 +00001228- Issue #2235: Added Py3k warnings for types which will become unhashable
1229 under the stricter __hash__ inheritance rules in 3.0. Several types
1230 which did not meet the rules for hash invariants and were already
1231 unhashable in 3.0 have now been explicitly flagged as unhashable in
1232 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1233 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1234
Brett Cannon88f801d2008-08-18 00:46:22 +00001235- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1236 imported into the module but exposed as part of the module's API.
1237
Brett Cannon7b96f072008-08-18 00:41:11 +00001238- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1239
Brett Cannon46225e72008-08-18 00:36:52 +00001240- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001242- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1243
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001244- Issue #3575: Incremental decoder's decode function now takes bytearray
1245 by using 's*' instead of 't#'.
1246
Jesus Cea585ad8a2009-07-02 15:37:21 +00001247- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001248 fails unicode conversion on 2nd parameter. (windows only)
1249
Facundo Batista94f243a2008-08-17 03:38:39 +00001250- Issue 2464. urllib2 now supports a malformation in the URL received
1251 in a redirect.
1252
Brett Cannonabe423e2008-08-16 21:47:07 +00001253- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001254 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001255
Facundo Batistaeb90b782008-08-16 14:44:07 +00001256- Issue #2776: fixed small issue when handling an URL with double slash
1257 after a 302 response in the case of not going through a proxy.
1258
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001259- Issue #2676: in the email package, content-type parsing was hanging on
1260 pathological input because of quadratic or exponential behaviour of a
1261 regular expression.
1262
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001263- Issue #3476: binary buffered reading through the new "io" library is now
1264 thread-safe.
1265
Brett Cannonbf3157b2008-08-14 05:00:03 +00001266- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1267 since mimetools itself is deprecated. Because modules are cached, all
1268 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1269
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001270- Issue #3134: shutil referenced undefined WindowsError symbol.
1271
Robert Schuppenies14646332008-08-10 11:01:53 +00001272- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1273 menu entries were not deleted.
1274
Brett Cannon83e81842008-08-09 23:30:55 +00001275- Copied the implementation of reduce() to _functools.reduce() to have a
1276 version that did not raise a DeprecationWarning under -3.
1277
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001278- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1279 a MemoryError rather than silently stop the iteration.
1280
Guido van Rossum59ce9012008-08-09 14:55:34 +00001281- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1282 to _sre.compile() will now be rejected. This should not affect anybody
1283 since the re.compile() function never generates invalid re-bytecode.
1284
Skip Montanaroa032bf42008-08-08 22:52:51 +00001285- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1286 upon first access it can be automatically initialized from the csv file if
1287 it wasn't initialized during instantiation.
1288
Brett Cannon3aa2a492008-08-06 22:28:09 +00001289- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1290 the reload() built-in has been removed.

Benjamin Peterson01a24322008-07-28 23:35:27 +00001303- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001304 asking for a specific length. This problem only affected files opened
1305 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001306

1331 file name rather than a ZipInfo instance, so files are extracted with
1332 mode 0600 rather than 000 under Unix.
1333
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001334- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1347 interaction with the tp_hash slot (added in 2.6b2) are now documented
1348
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001349- Issue #643841: The language reference now provides more detailed

1356================================
1357
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001358*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001360Core and Builtins
1361-----------------
1362
Georg Brandl3e483f62008-07-16 22:57:41 +00001363- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1364 its methods now allow for items objects that can be converted to
1365 an integer using operator.index().
1366
Mark Dickinson64b7e502008-07-16 09:40:03 +00001367- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1368 produced a ValueError instead of giving the correct float.
1369
Eric Smitha5fa5a22008-07-16 00:11:49 +00001370- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1371 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1372
Mark Dickinson7103aa42008-07-15 19:08:33 +00001373- Issue #3008: the float type has a new instance method 'float.hex'
1374 and a new class method 'float.fromhex' to convert floating-point
1375 numbers to and from hexadecimal strings, respectively.
1376
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001377- Issue #2235: __hash__ is once again inherited by default. To allow
1378 collections.Hashable to remain meaningful in the presence of the
1379 default hash implementation (object.__hash__), it is now possible
1380 to explicit block inheritance of hash by setting __hash__=None at
1381 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1382 level.
1383
Nick Coghlanb028f502008-07-13 14:52:36 +00001384- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1385 the parent module cannot be found while performing an absolute import.
1386 This means that an incorrectly defined __package__ attribute will
1387 now only prevent relative imports in that module rather than causing
1388 all imports from that module to fail.
1389
Nick Coghlan14ff9942008-07-08 14:21:42 +00001390- Issue #2517: Allow unicode messages in Exceptions again by correctly
1391 bypassing the instance dictionary when looking up __unicode__ on
1392 new-style classes.

1395 set to a custom object whose write() method happens to install
1396 another file in sys.stdout.

1399 threading.local: the first member set by a thread could be saved in
1400 another thread's dictionary.
1401
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001402- Issue #3004: Minor change to slice.indices(): the start and stop
1403 arguments are now treated identically, making the behaviour easier
1404 to describe and understand. For example, slice(None, -10,
1405 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1406 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1407 10, -1).
1408
Georg Brandl278fc502008-07-19 12:46:12 +00001409- Issue #3219: Calling a function with repeated keyword arguments,
1410 f(a=2, a=23), would not cause a syntax error. This was a regression
1411 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001412
Georg Brandl278fc502008-07-19 12:46:12 +00001413- Issue #2862: Make int and float freelist management consistent with
1414 other freelists. Changes their CompactFreeList apis into
1415 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00001420- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1421 api functions without holding the GIL, which could lead to a fatal
1422 error when they failed.
1423
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001424- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001449- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1450 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001451 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001452 content-length. The problem had been corrected in the 2.4 branch, but never
1453 merged into trunk.
1454
Georg Brandle78fbcc2008-07-05 10:13:36 +00001455- Issue #2663: add filtering capability to shutil.copytree().

Facundo Batista66c52772008-07-02 16:52:55 +00001467
Nick Coghlanc060b0e2008-07-02 13:09:19 +00001468- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1469 handling is now the same as that of other special attributes like __name__).
1470
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001471- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00001859- On MacOS X it is now possible to install the framework in 64-bit
1860 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001861 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001862
1863 This is controlled by the configure argument ``--with-universal-archs``:
1864
1865 - ``--with-universal-archs=all``: install 4-way universal
1866
1867 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1868
1869 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1870
1871 This option should be used in combination with ``--enable-universalsdk=``.
1872
1873 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

1878
Georg Brandl74a1dea2008-05-28 11:21:39 +00001879- Add ``PyType_Modified()`` as a public API to clear the type cache.
1880
1881- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00001882
1883- The PyString functions have been renamed to PyBytes. A batch of
1884 defines were added so that the linker still sees the original
1885 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001923- Issue #1631171: Re-implement the 'warnings' module in C (the
1924 original Python code has been kept as backup). This will allow for
1925 using the 'warning's machinery in such places as the parser where
1926 use of pure Python code is not possible. Both the ``showarning()``
1927 and ``formatwarning()`` gain an optional 'line' argument which is
1928 not called by default for backwards-compatibility reasons. Setting
1929 ``warnings.showwarning()`` to an implementation that lacks support
1930 for the ``line`` argument will raise a DeprecationWarning.

1954
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001955- The getpass module has been improved on Unix. It now uses /dev/tty
1956 by default and uses stderr instead of stdout. A GetPassWarning is
1957 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00001958

Georg Brandl3ee81df2008-05-17 18:14:43 +00001972- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001973 extension modules between 32 and 64 bit platforms. See the distutls

1986 so the controlled environment will more closely mirror the typical
1987 script environment. This supports setup.py scripts that refer to
1988 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001993- Issue #2550: The approach used by client/server code for obtaining
1994 ports to listen on in network-oriented tests has been refined in an
1995 effort to facilitate running multiple instances of the entire
1996 regression test suite in parallel without issue.
1997 test_support.bind_port() has been fixed such that it will always
1998 return a unique port -- which wasn't always the case with the
1999 previous implementation, especially if socket options had been set
2000 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2001 new implementation of bind_port() will actually raise an exception
2002 if it is passed an AF_INET/SOCK_STREAM socket with either the
2003 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2004 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2005 the socket it's been passed. This currently only applies to
2006 Windows. This option prevents any other sockets from binding to the
2007 host/port we've bound to, thus removing the possibility of the
2008 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2009 when a second SOCK_STREAM socket binds and accepts to a host/port
2010 that's already been bound by another socket. The optional preferred
2011 port parameter to bind_port() has been removed. Under no
2012 circumstances should tests be hard coding ports!
2013
2014 test_support.find_unused_port() has also been introduced, which will
2015 pass a temporary socket object to bind_port() in order to obtain an
2016 unused port. The temporary socket object is then closed and
2017 deleted, and the port is returned. This method should only be used
2018 for obtaining an unused port in order to pass to an external program
2019 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2020 a parameter to a server-oriented class that doesn't give you direct
2021 access to the underlying socket used.
2022
2023 Finally, test_support.HOST has been introduced, which should be used
2024 for the host argument of any relevant socket calls (i.e. bind and
2025 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002026
2027 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002028 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002029 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2030 test_asynchat and test_socket_ssl.
2031
Georg Brandl3ee81df2008-05-17 18:14:43 +00002032 It is now possible for multiple instances of the regression test
2033 suite to run in parallel without issue.

2300-----------------
2301
Fred Drakea8ee94b2008-03-01 02:45:07 +00002302- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002303 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002308
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002309- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002310 issue 215555 for a discussion.
2311
Eric Smitha73fbe72008-02-23 03:09:44 +00002312- Added the future_builtins module, which contains hex() and oct().
2313 These are the PEP 3127 version of these functions, designed to be
2314 compatible with the hex() and oct() builtins from Python 3.0. They
2315 differ slightly in their output formats from the existing, unchanged
2316 Python 2.6 builtins. The expected usage of the future_builtins
2317 module is:
2318 from future_builtins import hex, oct
2319
Eric Smith7ef40bf2008-02-20 23:34:22 +00002320- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2321 exponents for exponents with absolute value < 100. Follows C99
2322 standard. This is a change on Windows, which would use 3 digits.
2323 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2324 so that any alterations it does to the resulting string will be
2325 available in stringlib/formatter.h (for float.__format__).
2326
Eric Smith5a3c1352008-02-19 13:21:56 +00002327- Implemented PEP 3101, Advanced String Formatting. This adds a new
2328 builtin format(); a format() method for str and unicode; a
2329 __format__() method to object, str, unicode, int, long, float, and
2330 datetime; the class string.Formatter; and the C API
2331 PyObject_Format().
2332
Georg Brandl3ee81df2008-05-17 18:14:43 +00002333- Fixed several potential crashes, all caused by specially crafted
2334 __del__ methods exploiting objects in temporarily inconsistent
2335 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002336
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002337- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002338 prevent a possible crash: an Abstract Base Class would try to access
2339 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002344- Clear all free lists during a gc.collect() of the highest generation
2345 in order to allow pymalloc to free more arenas. Python may give back
2346 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002347
Georg Brandl3ee81df2008-05-17 18:14:43 +00002348- Issue #2045: Fix an infinite recursion triggered when printing a
2349 subclass of collections.defaultdict, if its default_factory is set
2350 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002351
Christian Heimesf75dbef2008-02-08 00:11:31 +00002352- Fixed a minor memory leak in dictobject.c. The content of the free
2353 list was not freed on interpreter shutdown.
2354
Georg Brandl3ee81df2008-05-17 18:14:43 +00002355- Limit free list of method and builtin function objects to 256
2356 entries each.

2359 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002360 to compact the internal free lists of pre-allocted ints and floats.
2361
Georg Brandl3ee81df2008-05-17 18:14:43 +00002362- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2363 calls. Python expected the return type int but the fork familie
2364 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002365

Georg Brandl3ee81df2008-05-17 18:14:43 +00002378- Patch #1473257: generator objects gain a gi_code attribute. This is
2379 the same object as the func_code attribute of the function that
2380 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002381
Georg Brandl3ee81df2008-05-17 18:14:43 +00002382- Issue #1920: "while 0" statements were completely removed by the
2383 compiler, even in the presence of an "else" clause, which is
2384 supposed to be run when the condition is false. Now the compiler
2385 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002386
Guido van Rossumeead05f2008-01-24 18:21:02 +00002387- A few crashers fixed: weakref_in_del.py (issue #1377858);
2388 loosing_dict_ref.py (issue #1303614, test67.py);
2389 borrowed_ref_[34].py (not in tracker).
2390
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002391- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002392 suppressed while an extension is loaded by calling SetErrorMode in
2393 dynload_win.c. The error is still reported properly.
2394
Georg Brandl3ee81df2008-05-17 18:14:43 +00002395- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002396 several extension methods and modules do not work without unicode
2397 support.
2398
Georg Brandl26543b12008-01-21 18:36:51 +00002399- Issue #1882: when compiling code from a string, encoding cookies in the
2400 second line of code were not always recognized correctly.
2401
Georg Brandl14404b62008-01-19 19:27:05 +00002402- Issue #1679: "0x" was taken as a valid integer literal.
2403
Georg Brandl6caad7d2008-01-26 14:19:22 +00002404- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002405 added.
2406
Christian Heimesc94e2b52008-01-14 04:13:37 +00002407- sys.float_info / PyFloat_GetInfo: The floating point information
2408 object was converted from a dict to a specialized structseq object.
2409
Georg Brandl3ee81df2008-05-17 18:14:43 +00002410- Patch #1816: Added sys.flags structseq. It exposes the status of
2411 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002412
Georg Brandl3ee81df2008-05-17 18:14:43 +00002413- Objects/structseq.c: Implemented new structseq representation. The
2414 patch makes structseqs (e.g. the return value of os.stat) more
2415 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002416
Georg Brandl3ee81df2008-05-17 18:14:43 +00002417- Patch #1700288: added a type attribute cache that caches method
2418 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002419
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002420- Bug #1776: __import__() no longer accepts filenames on any platform.
2421 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002422
Georg Brandlaed6c662008-01-07 17:25:53 +00002423- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2424
Georg Brandl3ee81df2008-05-17 18:14:43 +00002425- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2426 envvar and sys.dont_write_bytecode attribute. All these can be set
2427 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002428
Georg Brandl3ee81df2008-05-17 18:14:43 +00002429- Improve some exception messages when Windows fails to load an
2430 extension module. Now we get for example '%1 is not a valid Win32
2431 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002432
Georg Brandl3ee81df2008-05-17 18:14:43 +00002433- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002435- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2436 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002437
Christian Heimes0a8143f2007-12-18 23:22:54 +00002438- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002439 and INF. float("nan"), float("inf") and float("-inf") now work on
2440 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002441
Georg Brandl3ee81df2008-05-17 18:14:43 +00002442- Compiler now generates simpler and faster code for dictionary
2443 literals. The oparg for BUILD_MAP now indicates an estimated
2444 dictionary size. There is a new opcode, STORE_MAP, for adding
2445 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002446
Georg Brandl3ee81df2008-05-17 18:14:43 +00002447- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002455- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002456 SystemError.
2457
Nick Coghlanef01d822007-12-03 12:55:17 +00002458- PEP 366: Allow explicit relative imports when executing modules

2463 running, and if the deallocation of its frames somehow calls the
2464 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002465

2470
Georg Brandl3ee81df2008-05-17 18:14:43 +00002471- Issue #1460: The utf-7 incremental decoder did not accept truncated
2472 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002473
Georg Brandl3ee81df2008-05-17 18:14:43 +00002474- Patch #1739468: Directories and zipfiles containing a __main__.py
2475 file can now be directly executed by passing their name to the
2476 interpreter. The directory/zipfile is automatically inserted as the
2477 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002478
Georg Brandl3ee81df2008-05-17 18:14:43 +00002479- Issue #1265: Fix a problem with sys.settrace, if the tracing
2480 function uses a generator expression when at the same time the
2481 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002482
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002483- sets and frozensets now have an isdisjoint() method.
2484
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002485- optimize the performance of builtin.sum().
2486
Neal Norwitz44f326e2007-10-05 05:29:17 +00002487- Fix warnings found by the new version of the Coverity checker.
2488
Georg Brandl3ee81df2008-05-17 18:14:43 +00002489- The enumerate() builtin function is no longer bounded to sequences
2490 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2491 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002492
Georg Brandl3ee81df2008-05-17 18:14:43 +00002493- Issue #1686386: Tuple's tp_repr did not take into account the
2494 possibility of having a self-referential tuple, which is possible
2495 from C code. Nor did object's tp_str consider that a type's tp_str
2496 could do something that could lead to an inifinite recursion.
2497 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2498 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002499
Georg Brandl3ee81df2008-05-17 18:14:43 +00002500- Issue #1164: It was possible to trigger deadlock when using the
2501 'print' statement to write to a file since the GIL was not released
2502 as needed. Now PyObject_Print() does the right thing along with
2503 various tp_print implementations of the built-in types and those in
2504 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002505
Georg Brandl3ee81df2008-05-17 18:14:43 +00002506- Issue #1147: Exceptions were directly allowing string exceptions in
2507 their throw() method even though string exceptions no longer
2508 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002509
Georg Brandl3ee81df2008-05-17 18:14:43 +00002510- Issue #1096: Prevent a segfault from getting the repr of a very
2511 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002512
Brett Cannon1e534b52007-09-07 04:18:30 +00002513- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002514 PyObject_Call() never calling back out to Python code to trigger
2515 recursion depth updates/checks. Required the creation of a static
2516 RuntimeError instance in case normalizing an exception put the
2517 recursion check value past its limit. Fixes crashers
2518 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002519
Georg Brandl3ee81df2008-05-17 18:14:43 +00002520- Patch #1031213: Decode source line in SyntaxErrors back to its

2524 with %G.
2525
Georg Brandl3ee81df2008-05-17 18:14:43 +00002526- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00002533- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002534 __*__ attributes. (Some already existed, e.g., __doc__ and
2535 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002536
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002537- Add -3 option to the interpreter to warn about features that are
2538 deprecated and will be changed/removed in Python 3.0.
2539
Georg Brandl2134e752007-05-21 20:34:16 +00002540- Patch #1686487: you can now pass any mapping after '**' in function
2541 calls.
2542
Collin Winter62903052007-05-18 23:11:24 +00002543- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002544 "except E as target:". This is to provide forwards compatibility
2545 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002546
Brett Cannon229cee22007-05-05 01:34:02 +00002547- Deprecate BaseException.message as per PEP 352.
2548
Georg Brandl3ee81df2008-05-17 18:14:43 +00002549- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002550 inherited from a builtin base.
2551
Vinay Sajip8549ce32007-05-06 17:53:37 +00002552- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002553 setting a plain string, ie don't expand to single letter identifiers.
2554
Raymond Hettinger13936692007-04-11 18:40:58 +00002555- Request #1191699: Slices can now be pickled.
2556
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002557- Request #1193128: str.translate() now allows a None argument for
2558 translations that only remove characters without re-mapping the
2559 remaining characters.
2560
Georg Brandl5cb76c12007-03-21 09:00:39 +00002561- Patch #1682205: a TypeError while unpacking an iterable is no longer
2562 masked by a generic one with the message "unpack non-sequence".
2563
Neal Norwitzaa754b72007-03-21 06:39:48 +00002564- Remove unused file Python/fmod.c.
2565
Guido van Rossum143b5642007-03-23 04:58:42 +00002566- Bug #1683368: The object.__init__() and object.__new__() methods are
2567 now stricter in rejecting excess arguments. The only time when
2568 either allows excess arguments is when it is not overridden and the
2569 other one is. For backwards compatibility, when both are
2570 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002571 warning later). Also, type.__init__() insists on the same signature
2572 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002573
Georg Brandl3ee81df2008-05-17 18:14:43 +00002574- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2575 object to complex using its __complex__() method before falling back
2576 to the __float__() method. Therefore, the functions in the cmath
2577 module now can operate on objects that define a __complex__()
2578 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002579
Georg Brandl3ee81df2008-05-17 18:14:43 +00002580- Patch #1623563: allow __class__ assignment for classes with
2581 __slots__. The old and the new class are still required to have the
2582 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002583
Georg Brandl3ee81df2008-05-17 18:14:43 +00002584- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002587- Patch #1462488: Python no longer segfaults when
2588 ``object.__reduce_ex__()`` is called with an object that is faking
2589 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002590
Georg Brandl3ee81df2008-05-17 18:14:43 +00002591- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002594- Patch #1444529: the builtin compile() now accepts keyword arguments.
2595
Georg Brandl7b9c5552007-03-12 14:30:05 +00002596- Bug #1678647: write a newline after printing an exception in any
2597 case, even when converting the value to a string failed.
2598
Georg Brandl871f1bc2007-03-12 13:17:36 +00002599- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002600 its argument, if it exists. If not, it will work like before. This
2601 allows customizing the output of dir() in the presence of a
2602 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002603
Collin Winter276887b2007-03-12 16:11:39 +00002604- Patch #922167: Python no longer segfaults when faced with infinitely
2605 self-recursive reload() calls (as reported by bug #742342).
2606
Georg Brandl3ee81df2008-05-17 18:14:43 +00002607- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002610- Patch #1491866: change the complex() constructor to allow
2611 parthensized forms. This means complex(repr(x)) now works instead of
2612 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002613
Georg Brandlaa2321b2007-03-07 00:40:28 +00002614- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002615 makes the filenames the warning module prints much more sensible
2616 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002617

3124
Facundo Batistad918a652007-04-24 13:54:38 +00003125- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003126 the client's request was successfully received, understood, and
3127 accepted. Now in these cases no error is raised in urllib (issue
3128 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00003129

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003136- Added a timeout parameter to the constructor of other protocols
3137 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3138 work started with create_connection() and timeout in httplib, and
3139 closes patch #723312.
3140
Vinay Sajip8549ce32007-05-06 17:53:37 +00003141- Patch #1676823: Added create_connection() to socket.py, which may be
3142 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003143 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003144
Martin v. Löwis0af33882007-03-23 13:27:15 +00003145- Bug #978833: Revert r50844, as it broke _socketobject.dup.

3165
Georg Brandlf66b6032007-03-14 08:27:52 +00003166- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003167 AttributeError instead of an IOError when the server's response
3168 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003169
Georg Brandl3ee81df2008-05-17 18:14:43 +00003170- Patch #957650: "%var%" environment variable references are now
3171 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00003173
Georg Brandl3ee81df2008-05-17 18:14:43 +00003174- Patch #1429539: pdb now correctly initializes the __main__ module
3175 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003176 correctly now.
3177
Georg Brandlbad6f192007-03-13 21:32:56 +00003178- The nonobvious commands.getstatus() function is now deprecated.

3184
Georg Brandl3ee81df2008-05-17 18:14:43 +00003185- Patch #1530482: add pydoc.render_doc() which returns the
3186 documentation for a thing instead of paging it to stdout, which
3187 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00003188
Georg Brandl3ee81df2008-05-17 18:14:43 +00003189- Patch #1533909: the timeit module now accepts callables in addition

3196 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00003197
Georg Brandl9e6b4702007-03-13 18:15:41 +00003198- Patch #1581073: add a flag to textwrap that prevents the dropping of
3199 whitespace while wrapping.
3200
Georg Brandl92a6bae2007-03-13 17:43:32 +00003201- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003202 are set for invalid interpolation sequences that would lead to
3203 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00003204

Georg Brandl3ee81df2008-05-17 18:14:43 +00003219 field names in its exception message if you try to write a record
3220 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00003238

3246 returned string up to the first NUL character.

3257
Georg Brandl3ee81df2008-05-17 18:14:43 +00003258- unittest now verifies more of its assumptions. In particular,
3259 TestCase and TestSuite subclasses (not instances) are no longer
3260 accepted in TestSuite.addTest(). This should cause no
3261 incompatibility since it never made sense with ordinary subclasses
3262 -- the failure just occurred later, with a more cumbersome
3263 exception.

3272 given a unicode argument and os.listdir() returns unicode filenames.
3273
Georg Brandl3ee81df2008-05-17 18:14:43 +00003274- Patch #1673619: setup.py identifies extension modules it doesn't

3276 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003652 time so that opening a database previously created with the DB_DUP
3653 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3654 opens. Specifically: dictionary assignment to a DB object will
3655 replace all values for a given key when the database allows
3656 duplicate values. DB users should use DB.put(k, v) when they want
3657 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003658

3664 characters with ASCII value less than 32. Also, it correctly quotes
3665 dots only if they occur on a single line, as opposed to the previous
3666 behavior of quoting dots if they are the second character of any
3667 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003668
