121
Antoine Pitrou0b074572010-01-08 19:21:34 +0000122- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
123 renaming of `cPickle` to `pickle`. The warning was annoying since there's

184 reading from stdin so that existing input does not confuse it and

195 than the current precision) in shift and rotate.
196
R. David Murray7034db32009-10-27 23:39:06 +0000197- Issue #7082: When falling back to the MIME 'name' parameter, the

199
Mark Dickinson20a7cfc2009-10-27 18:27:53 +0000200- Issue #7099: Decimal.is_normal now returns True for numbers with exponent

Georg Brandld2094602008-12-05 08:51:30 +0000759 method on file objects with closefd=False. The file descriptor is still

762
Georg Brandlfa71a902008-12-05 09:08:28 +0000763- Issue #3689: The list reversed iterator now supports __length_hint__

1134What's New in Python 2.6.1
1135==========================
1136
1137*Release date: 04-Dec-2008*
1138
1139Core and Builtins
1140-----------------
1141
1142- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1143 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1144 instead of throwing a MemoryError.
1145
1146- Issue #4367: Python would segfault during compiling when the unicodedata
1147 module couldn't be imported and \N escapes were present.
1148
1149- Issue #4348: Some bytearray methods returned that didn't cause any change to
1150 the bytearray, returned the same bytearray instead of a copy.
1151
1152- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1153
1154- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1155
1156- Issue #4048: The parser module now correctly validates relative imports.
1157
1158- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1159 exec statement.
1160
1161- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1162 method does not return iterators for the 4th and 5th items.
1163
1164- Issue #4209: Enabling unicode_literals and the print_function in the same
1165 __future__ import didn't work.
1166
1167- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1168 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1169 really executed because I cannot move to such directory on win2k)
1170
1171- Issue #4069: When set.remove(element) is used with a set element, the element
1172 is temporarily replaced with an equivalent frozenset. But the eventual
1173 KeyError would always report the empty frozenset([]) as the missing key. Now
1174 it correctly refers to the initial element.
1175
1176- Fixed C99 style comments in several files. Python is now C89 compatible
1177 again.

1323
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001324- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1325
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001326- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1327 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1328 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1329 ``printf`` function, whereas PyString_FromFormat has an independent
1330 implementation and uses "%zd" on all platforms for size_t values.
1331 This makes a difference on win64, where ``printf`` needs "%Id" to display
1332 64bit values.
1333
Benjamin Peterson97179b02008-09-09 20:55:01 +00001334- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1335 error.
1336
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001337- Issue #3777: long() applied to a float object now always return a long
1338 object; previously an int would be returned for small values. the __long__
1339 method is allowed to return either an int or a long, but the behaviour of
1340 float objects should not change to respect backward compatibility.
1341
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001342- Issue #3751: str.rpartition would perform a left-partition when called with
1343 a unicode argument.
1344
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001345- Issue #3683: Fix compilation when --without-threads is given.
1346
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001347- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001348 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001349 was correctly parsed but parsing of subsequent arguments failed.
1350
Vinay Sajip35e3b032008-09-01 14:33:59 +00001351- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001352 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1353 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1354 when given a tuple of classes as second argument, were looking up
1355 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1356 type object.
1357
Neal Norwitz18aa3882008-08-24 05:04:52 +00001358- Fix crashes on memory allocation failure found with failmalloc.
1359
1360- Fix memory leaks found with valgrind and update suppressions file.
1361
1362- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1363
1364- Fix problem using wrong name in decimal module reported by pychecker.
1365
Christian Heimes7d4c3172008-08-22 19:47:25 +00001366- Silenced another compiler warning about a used but not defined
1367 function 'stringlib_contains_obj'.

1370 ``__delslice__``.
1371
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001372- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1373 library targets in the Makefile.
1374
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001375- Issue #1204: The configure script now tests for additional libraries
1376 that may be required when linking against readline. This fixes issues
1377 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00001394- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
1395 silent misbehaviour when a single instance is nested in multiple
1396 with statements, or when the methods are invoked in the wrong order.
1397
Vinay Sajip844f7412008-09-09 13:42:08 +00001398- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
1399
Nick Coghland2e09382008-09-11 12:11:06 +00001400- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001401 return a list or None rather than a custom object.
1402
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001403- Issue #1638033: Cookie.Morsel gained the httponly attribute.

1427 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1428 for catch_warnings() also led to an improvement in the raising of a
1429 DeprecationWarning related to warnings.warn_explicit().
1430
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001431- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001492What's New in Python 2.6 beta 3?
1493================================
1494
Barry Warsaw07a4a382008-08-21 01:15:08 +00001495*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001496
1497Core and Builtins
1498-----------------
1499
Guido van Rossumf8402962008-08-20 15:01:50 +00001500- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1501 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1502 extensions do not automatically benefit from the class attribute
1503 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1504 to their tp_flags field if they care. This is a backwards
1505 compatibility feature; in 3.0, all types will use the cache by
1506 default.
1507
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001508- Keyword arguments can now follow starred arguments. (``f(a, *args,
1509 keyword=23)`` is now valid syntax.)
1510
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001511- ctypes function pointers that are COM methods have a boolean True
1512 value again.
1513
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001514- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1515 by denying s# to parse objects that have a releasebuffer procedure,
1516 and introducing s*.
1517
Georg Brandl1e13ea92008-08-11 09:07:59 +00001518- Issue #3537: Fix an assertion failure when an empty but presized dict
1519 object was stored in the freelist.
1520
Mark Dickinsonb6467572008-08-04 21:30:09 +00001521- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1522 ValueError consistently across platforms.
1523
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001524- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1525 (64bit Unix, for example), unichr() would truncate its argument and return
1526 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1527
Neal Norwitze7d8be82008-07-31 17:17:14 +00001528- Apply security patches from Apple.
1529
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001530- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1531 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1532
Antoine Pitrou92f82162008-07-25 22:22:08 +00001533- Issue #1819: function calls with several named parameters are now on
1534 average 35% faster (as measured by pybench).
1535
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001536- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1537 the python debugger steps into a class statement: the free variables (local
1538 variables defined in an outer scope) would be deleted from the outer scope.
1539
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001540- Issue #2620: Overflow checking when allocating or reallocating memory
1541 was not always being done properly in some python types and extension
1542 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1543 all been updated to perform better checks and places in the code that
1544 would previously leak memory on the error path when such an allocation
1545 failed have been fixed.

1551
Benjamin Petersone977ad42008-08-20 01:42:01 +00001552- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1553 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1554
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001555- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1556 version reported by these tools does not necessarily follow the python
1557 version numbering scheme, so the module is less strict when parsing it.
1558
Nick Coghlanf70385a2008-08-18 12:42:46 +00001559- Issue #2235: Added Py3k warnings for types which will become unhashable
1560 under the stricter __hash__ inheritance rules in 3.0. Several types
1561 which did not meet the rules for hash invariants and were already
1562 unhashable in 3.0 have now been explicitly flagged as unhashable in
1563 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1564 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1565
Brett Cannon88f801d2008-08-18 00:46:22 +00001566- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1567 imported into the module but exposed as part of the module's API.
1568
Brett Cannon7b96f072008-08-18 00:41:11 +00001569- Remove an unneeded import of abc.ABCMeta from 'inspect'.

1574
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001575- Issue #3575: Incremental decoder's decode function now takes bytearray
1576 by using 's*' instead of 't#'.
1577
Jesus Cea585ad8a2009-07-02 15:37:21 +00001578- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001579 fails unicode conversion on 2nd parameter. (windows only)
1580
Facundo Batista94f243a2008-08-17 03:38:39 +00001581- Issue 2464. urllib2 now supports a malformation in the URL received
1582 in a redirect.

Brett Cannonabe423e2008-08-16 21:47:07 +00001586
Facundo Batistaeb90b782008-08-16 14:44:07 +00001587- Issue #2776: fixed small issue when handling an URL with double slash

Antoine Pitroude781a42008-08-09 12:43:23 +00001635 asking for a specific length. This problem only affected files opened

1679
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001680- Issue #643841: The language reference now provides more detailed

1692-----------------
1693
Georg Brandl3e483f62008-07-16 22:57:41 +00001694- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1695 its methods now allow for items objects that can be converted to
1696 an integer using operator.index().
1697
Mark Dickinson64b7e502008-07-16 09:40:03 +00001698- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1699 produced a ValueError instead of giving the correct float.
1700
Eric Smitha5fa5a22008-07-16 00:11:49 +00001701- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1702 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1703
Mark Dickinson7103aa42008-07-15 19:08:33 +00001704- Issue #3008: the float type has a new instance method 'float.hex'
1705 and a new class method 'float.fromhex' to convert floating-point
1706 numbers to and from hexadecimal strings, respectively.
1707
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001708- Issue #2235: __hash__ is once again inherited by default. To allow
1709 collections.Hashable to remain meaningful in the presence of the
1710 default hash implementation (object.__hash__), it is now possible
1711 to explicit block inheritance of hash by setting __hash__=None at
1712 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1713 level.
1714
Nick Coghlanb028f502008-07-13 14:52:36 +00001715- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1716 the parent module cannot be found while performing an absolute import.
1717 This means that an incorrectly defined __package__ attribute will
1718 now only prevent relative imports in that module rather than causing
1719 all imports from that module to fail.
1720
Nick Coghlan14ff9942008-07-08 14:21:42 +00001721- Issue #2517: Allow unicode messages in Exceptions again by correctly
1722 bypassing the instance dictionary when looking up __unicode__ on
1723 new-style classes.

1731 another thread's dictionary.
1732
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001733- Issue #3004: Minor change to slice.indices(): the start and stop
1734 arguments are now treated identically, making the behaviour easier
1735 to describe and understand. For example, slice(None, -10,
1736 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1737 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1738 10, -1).
1739
Georg Brandl278fc502008-07-19 12:46:12 +00001740- Issue #3219: Calling a function with repeated keyword arguments,
1741 f(a=2, a=23), would not cause a syntax error. This was a regression
1742 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00001744- Issue #2862: Make int and float freelist management consistent with
1745 other freelists. Changes their CompactFreeList apis into

1752 api functions without holding the GIL, which could lead to a fatal
1753 error when they failed.
1754
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001755- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001780- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1781 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001782 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001783 content-length. The problem had been corrected in the 2.4 branch, but never
1784 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001799- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Vinay Sajip9828b7e2008-06-17 11:04:02 +00002170- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002171 environment to control the '-arch' flags that are used to build
2172 an extension. This was added for compatibility with Apple's build
2173 of Python.
2174
2175- The bundled OSX-specific copy of libbffi is now in sync with the version
2176 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
2177

2187
Brett Cannonb61d8012008-05-11 23:39:04 +00002188- ``Lib/lib-old`` is now added to sys.path.
2189
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002190- On MacOS X it is now possible to install the framework in 64-bit
2191 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002192 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002193
2194 This is controlled by the configure argument ``--with-universal-archs``:
2195
2196 - ``--with-universal-archs=all``: install 4-way universal
2197
2198 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2199
2200 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2201
2202 This option should be used in combination with ``--enable-universalsdk=``.
2203
2204 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002254- Issue #1631171: Re-implement the 'warnings' module in C (the
2255 original Python code has been kept as backup). This will allow for
2256 using the 'warning's machinery in such places as the parser where
2257 use of pure Python code is not possible. Both the ``showarning()``
2258 and ``formatwarning()`` gain an optional 'line' argument which is
2259 not called by default for backwards-compatibility reasons. Setting
2260 ``warnings.showwarning()`` to an implementation that lacks support
2261 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002286- The getpass module has been improved on Unix. It now uses /dev/tty
2287 by default and uses stderr instead of stdout. A GetPassWarning is
2288 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002303- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002304 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002324- Issue #2550: The approach used by client/server code for obtaining
2325 ports to listen on in network-oriented tests has been refined in an
2326 effort to facilitate running multiple instances of the entire
2327 regression test suite in parallel without issue.
2328 test_support.bind_port() has been fixed such that it will always
2329 return a unique port -- which wasn't always the case with the
2330 previous implementation, especially if socket options had been set
2331 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2332 new implementation of bind_port() will actually raise an exception
2333 if it is passed an AF_INET/SOCK_STREAM socket with either the
2334 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2335 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2336 the socket it's been passed. This currently only applies to
2337 Windows. This option prevents any other sockets from binding to the
2338 host/port we've bound to, thus removing the possibility of the
2339 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2340 when a second SOCK_STREAM socket binds and accepts to a host/port
2341 that's already been bound by another socket. The optional preferred
2342 port parameter to bind_port() has been removed. Under no
2343 circumstances should tests be hard coding ports!
2344
2345 test_support.find_unused_port() has also been introduced, which will
2346 pass a temporary socket object to bind_port() in order to obtain an
2347 unused port. The temporary socket object is then closed and
2348 deleted, and the port is returned. This method should only be used
2349 for obtaining an unused port in order to pass to an external program
2350 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2351 a parameter to a server-oriented class that doesn't give you direct
2352 access to the underlying socket used.
2353
2354 Finally, test_support.HOST has been introduced, which should be used
2355 for the host argument of any relevant socket calls (i.e. bind and
2356 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002357
2358 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002359 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002360 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2361 test_asynchat and test_socket_ssl.
2362
Georg Brandl3ee81df2008-05-17 18:14:43 +00002363 It is now possible for multiple instances of the regression test
2364 suite to run in parallel without issue.

2631-----------------
2632
Fred Drakea8ee94b2008-03-01 02:45:07 +00002633- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002634 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002639
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002640- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002641 issue 215555 for a discussion.
2642
Eric Smitha73fbe72008-02-23 03:09:44 +00002643- Added the future_builtins module, which contains hex() and oct().
2644 These are the PEP 3127 version of these functions, designed to be
2645 compatible with the hex() and oct() builtins from Python 3.0. They
2646 differ slightly in their output formats from the existing, unchanged
2647 Python 2.6 builtins. The expected usage of the future_builtins
2648 module is:
2649 from future_builtins import hex, oct
2650
Eric Smith7ef40bf2008-02-20 23:34:22 +00002651- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2652 exponents for exponents with absolute value < 100. Follows C99
2653 standard. This is a change on Windows, which would use 3 digits.
2654 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2655 so that any alterations it does to the resulting string will be
2656 available in stringlib/formatter.h (for float.__format__).
2657
Eric Smith5a3c1352008-02-19 13:21:56 +00002658- Implemented PEP 3101, Advanced String Formatting. This adds a new
2659 builtin format(); a format() method for str and unicode; a
2660 __format__() method to object, str, unicode, int, long, float, and
2661 datetime; the class string.Formatter; and the C API
2662 PyObject_Format().
2663
Georg Brandl3ee81df2008-05-17 18:14:43 +00002664- Fixed several potential crashes, all caused by specially crafted
2665 __del__ methods exploiting objects in temporarily inconsistent
2666 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00002668- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002669 prevent a possible crash: an Abstract Base Class would try to access
2670 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002671

2673 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002674
Georg Brandl3ee81df2008-05-17 18:14:43 +00002675- Clear all free lists during a gc.collect() of the highest generation
2676 in order to allow pymalloc to free more arenas. Python may give back
2677 memory to the OS earlier.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002679- Issue #2045: Fix an infinite recursion triggered when printing a
2680 subclass of collections.defaultdict, if its default_factory is set
2681 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002682
Christian Heimesf75dbef2008-02-08 00:11:31 +00002683- Fixed a minor memory leak in dictobject.c. The content of the free
2684 list was not freed on interpreter shutdown.
2685
Georg Brandl3ee81df2008-05-17 18:14:43 +00002686- Limit free list of method and builtin function objects to 256
2687 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002688
Georg Brandl3ee81df2008-05-17 18:14:43 +00002689- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2690 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002691 to compact the internal free lists of pre-allocted ints and floats.
2692
Georg Brandl3ee81df2008-05-17 18:14:43 +00002693- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2694 calls. Python expected the return type int but the fork familie
2695 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002696
Georg Brandl3ee81df2008-05-17 18:14:43 +00002697- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2698 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002699
Georg Brandl3ee81df2008-05-17 18:14:43 +00002700- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2701 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002702
Georg Brandl3ee81df2008-05-17 18:14:43 +00002703- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2704 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00002706- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2707 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002708
Georg Brandl3ee81df2008-05-17 18:14:43 +00002709- Patch #1473257: generator objects gain a gi_code attribute. This is
2710 the same object as the func_code attribute of the function that
2711 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002712
Georg Brandl3ee81df2008-05-17 18:14:43 +00002713- Issue #1920: "while 0" statements were completely removed by the
2714 compiler, even in the presence of an "else" clause, which is
2715 supposed to be run when the condition is false. Now the compiler
2716 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002717
Guido van Rossumeead05f2008-01-24 18:21:02 +00002718- A few crashers fixed: weakref_in_del.py (issue #1377858);
2719 loosing_dict_ref.py (issue #1303614, test67.py);
2720 borrowed_ref_[34].py (not in tracker).
2721
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002722- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002723 suppressed while an extension is loaded by calling SetErrorMode in
2724 dynload_win.c. The error is still reported properly.
2725
Georg Brandl3ee81df2008-05-17 18:14:43 +00002726- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002727 several extension methods and modules do not work without unicode
2728 support.
2729
Georg Brandl26543b12008-01-21 18:36:51 +00002730- Issue #1882: when compiling code from a string, encoding cookies in the
2731 second line of code were not always recognized correctly.
2732
Georg Brandl14404b62008-01-19 19:27:05 +00002733- Issue #1679: "0x" was taken as a valid integer literal.
2734
Georg Brandl6caad7d2008-01-26 14:19:22 +00002735- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002736 added.
2737
Christian Heimesc94e2b52008-01-14 04:13:37 +00002738- sys.float_info / PyFloat_GetInfo: The floating point information
2739 object was converted from a dict to a specialized structseq object.
2740
Georg Brandl3ee81df2008-05-17 18:14:43 +00002741- Patch #1816: Added sys.flags structseq. It exposes the status of
2742 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002743
Georg Brandl3ee81df2008-05-17 18:14:43 +00002744- Objects/structseq.c: Implemented new structseq representation. The
2745 patch makes structseqs (e.g. the return value of os.stat) more
2746 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002747
Georg Brandl3ee81df2008-05-17 18:14:43 +00002748- Patch #1700288: added a type attribute cache that caches method
2749 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002750
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002751- Bug #1776: __import__() no longer accepts filenames on any platform.
2752 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002753
Georg Brandlaed6c662008-01-07 17:25:53 +00002754- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2755
Georg Brandl3ee81df2008-05-17 18:14:43 +00002756- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2757 envvar and sys.dont_write_bytecode attribute. All these can be set
2758 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002759
Georg Brandl3ee81df2008-05-17 18:14:43 +00002760- Improve some exception messages when Windows fails to load an
2761 extension module. Now we get for example '%1 is not a valid Win32
2762 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002763
Georg Brandl3ee81df2008-05-17 18:14:43 +00002764- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002766- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2767 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002768
Christian Heimes0a8143f2007-12-18 23:22:54 +00002769- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002770 and INF. float("nan"), float("inf") and float("-inf") now work on
2771 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002772
Georg Brandl3ee81df2008-05-17 18:14:43 +00002773- Compiler now generates simpler and faster code for dictionary
2774 literals. The oparg for BUILD_MAP now indicates an estimated
2775 dictionary size. There is a new opcode, STORE_MAP, for adding
2776 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002777
Georg Brandl3ee81df2008-05-17 18:14:43 +00002778- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002786- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002787 SystemError.
2788
Nick Coghlanef01d822007-12-03 12:55:17 +00002789- PEP 366: Allow explicit relative imports when executing modules

2794 running, and if the deallocation of its frames somehow calls the
2795 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002796

2801
Georg Brandl3ee81df2008-05-17 18:14:43 +00002802- Issue #1460: The utf-7 incremental decoder did not accept truncated
2803 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002804
Georg Brandl3ee81df2008-05-17 18:14:43 +00002805- Patch #1739468: Directories and zipfiles containing a __main__.py
2806 file can now be directly executed by passing their name to the
2807 interpreter. The directory/zipfile is automatically inserted as the
2808 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002809
Georg Brandl3ee81df2008-05-17 18:14:43 +00002810- Issue #1265: Fix a problem with sys.settrace, if the tracing
2811 function uses a generator expression when at the same time the
2812 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002813
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002814- sets and frozensets now have an isdisjoint() method.
2815
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002816- optimize the performance of builtin.sum().
2817
Neal Norwitz44f326e2007-10-05 05:29:17 +00002818- Fix warnings found by the new version of the Coverity checker.
2819
Georg Brandl3ee81df2008-05-17 18:14:43 +00002820- The enumerate() builtin function is no longer bounded to sequences
2821 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2822 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002823
Georg Brandl3ee81df2008-05-17 18:14:43 +00002824- Issue #1686386: Tuple's tp_repr did not take into account the
2825 possibility of having a self-referential tuple, which is possible
2826 from C code. Nor did object's tp_str consider that a type's tp_str
2827 could do something that could lead to an inifinite recursion.
2828 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2829 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002830
Georg Brandl3ee81df2008-05-17 18:14:43 +00002831- Issue #1164: It was possible to trigger deadlock when using the
2832 'print' statement to write to a file since the GIL was not released
2833 as needed. Now PyObject_Print() does the right thing along with
2834 various tp_print implementations of the built-in types and those in
2835 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002836
Georg Brandl3ee81df2008-05-17 18:14:43 +00002837- Issue #1147: Exceptions were directly allowing string exceptions in
2838 their throw() method even though string exceptions no longer
2839 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002840
Georg Brandl3ee81df2008-05-17 18:14:43 +00002841- Issue #1096: Prevent a segfault from getting the repr of a very
2842 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002843
Brett Cannon1e534b52007-09-07 04:18:30 +00002844- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002845 PyObject_Call() never calling back out to Python code to trigger
2846 recursion depth updates/checks. Required the creation of a static
2847 RuntimeError instance in case normalizing an exception put the
2848 recursion check value past its limit. Fixes crashers
2849 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002850
Georg Brandl3ee81df2008-05-17 18:14:43 +00002851- Patch #1031213: Decode source line in SyntaxErrors back to its

2855 with %G.
2856
Georg Brandl3ee81df2008-05-17 18:14:43 +00002857- Prevent expandtabs() on string and unicode objects from causing a
2858 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002864- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002865 __*__ attributes. (Some already existed, e.g., __doc__ and
2866 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002867
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002868- Add -3 option to the interpreter to warn about features that are
2869 deprecated and will be changed/removed in Python 3.0.
2870
Georg Brandl2134e752007-05-21 20:34:16 +00002871- Patch #1686487: you can now pass any mapping after '**' in function
2872 calls.
2873
Collin Winter62903052007-05-18 23:11:24 +00002874- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002875 "except E as target:". This is to provide forwards compatibility
2876 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002877
Brett Cannon229cee22007-05-05 01:34:02 +00002878- Deprecate BaseException.message as per PEP 352.
2879
Georg Brandl3ee81df2008-05-17 18:14:43 +00002880- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002881 inherited from a builtin base.
2882
Vinay Sajip8549ce32007-05-06 17:53:37 +00002883- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002884 setting a plain string, ie don't expand to single letter identifiers.
2885
Raymond Hettinger13936692007-04-11 18:40:58 +00002886- Request #1191699: Slices can now be pickled.
2887
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002888- Request #1193128: str.translate() now allows a None argument for
2889 translations that only remove characters without re-mapping the
2890 remaining characters.
2891
Georg Brandl5cb76c12007-03-21 09:00:39 +00002892- Patch #1682205: a TypeError while unpacking an iterable is no longer
2893 masked by a generic one with the message "unpack non-sequence".
2894
Neal Norwitzaa754b72007-03-21 06:39:48 +00002895- Remove unused file Python/fmod.c.
2896
Guido van Rossum143b5642007-03-23 04:58:42 +00002897- Bug #1683368: The object.__init__() and object.__new__() methods are
2898 now stricter in rejecting excess arguments. The only time when
2899 either allows excess arguments is when it is not overridden and the
2900 other one is. For backwards compatibility, when both are
2901 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002902 warning later). Also, type.__init__() insists on the same signature
2903 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002904
Georg Brandl3ee81df2008-05-17 18:14:43 +00002905- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2906 object to complex using its __complex__() method before falling back
2907 to the __float__() method. Therefore, the functions in the cmath
2908 module now can operate on objects that define a __complex__()
2909 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002910
Georg Brandl3ee81df2008-05-17 18:14:43 +00002911- Patch #1623563: allow __class__ assignment for classes with
2912 __slots__. The old and the new class are still required to have the
2913 same slot names.

3016 embedded in the string to convert.
3017

Georg Brandl3ee81df2008-05-17 18:14:43 +00003983 time so that opening a database previously created with the DB_DUP
3984 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3985 opens. Specifically: dictionary assignment to a DB object will
3986 replace all values for a given key when the database allows
3987 duplicate values. DB users should use DB.put(k, v) when they want
3988 to store duplicates; not DB[k] = v.

3995 characters with ASCII value less than 32. Also, it correctly quotes
3996 dots only if they occur on a single line, as opposed to the previous
3997 behavior of quoting dots if they are the second character of any
3998 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003999
