1145What's New in Python 2.6.1
1146==========================
1147
1148*Release date: 04-Dec-2008*
1149
1150Core and Builtins
1151-----------------
1152
1153- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1154 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1155 instead of throwing a MemoryError.
1156
1157- Issue #4367: Python would segfault during compiling when the unicodedata
1158 module couldn't be imported and \N escapes were present.
1159
1160- Issue #4348: Some bytearray methods returned that didn't cause any change to
1161 the bytearray, returned the same bytearray instead of a copy.
1162
1163- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1164
1165- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1166
1167- Issue #4048: The parser module now correctly validates relative imports.
1168
1169- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1170 exec statement.
1171
1172- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1173 method does not return iterators for the 4th and 5th items.
1174
1175- Issue #4209: Enabling unicode_literals and the print_function in the same
1176 __future__ import didn't work.
1177
1178- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1179 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1180 really executed because I cannot move to such directory on win2k)
1181
1182- Issue #4069: When set.remove(element) is used with a set element, the element
1183 is temporarily replaced with an equivalent frozenset. But the eventual
1184 KeyError would always report the empty frozenset([]) as the missing key. Now
1185 it correctly refers to the initial element.
1186
1187- Fixed C99 style comments in several files. Python is now C89 compatible
1188 again.

1315- Issue #3850: recursion tests in Misc/find_recursion_limit.py can raise
1316 AttributeError instead of RuntimeError, depending in which C API call
1317 exactly the recursion limit is exceeded. Consequently, both exception types
1318 are caught and silenced.

1334
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001335- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1336
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001337- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1338 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1339 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1340 ``printf`` function, whereas PyString_FromFormat has an independent
1341 implementation and uses "%zd" on all platforms for size_t values.
1342 This makes a difference on win64, where ``printf`` needs "%Id" to display
1343 64bit values.
1344
Benjamin Peterson97179b02008-09-09 20:55:01 +00001345- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1346 error.
1347
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001348- Issue #3777: long() applied to a float object now always return a long
1349 object; previously an int would be returned for small values. the __long__
1350 method is allowed to return either an int or a long, but the behaviour of
1351 float objects should not change to respect backward compatibility.
1352
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001353- Issue #3751: str.rpartition would perform a left-partition when called with
1354 a unicode argument.
1355
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001356- Issue #3683: Fix compilation when --without-threads is given.
1357
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001358- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001359 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001360 was correctly parsed but parsing of subsequent arguments failed.
1361
Vinay Sajip35e3b032008-09-01 14:33:59 +00001362- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001363 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1364 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1365 when given a tuple of classes as second argument, were looking up
1366 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1367 type object.
1368
Neal Norwitz18aa3882008-08-24 05:04:52 +00001369- Fix crashes on memory allocation failure found with failmalloc.
1370
1371- Fix memory leaks found with valgrind and update suppressions file.
1372
1373- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1374
1375- Fix problem using wrong name in decimal module reported by pychecker.
1376
Christian Heimes7d4c3172008-08-22 19:47:25 +00001377- Silenced another compiler warning about a used but not defined
1378 function 'stringlib_contains_obj'.

1381 ``__delslice__``.
1382
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001383- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1384 library targets in the Makefile.
1385
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001386- Issue #1204: The configure script now tests for additional libraries
1387 that may be required when linking against readline. This fixes issues
1388 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00001405- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
1406 silent misbehaviour when a single instance is nested in multiple
1407 with statements, or when the methods are invoked in the wrong order.
1408
Vinay Sajip844f7412008-09-09 13:42:08 +00001409- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
1410
Nick Coghland2e09382008-09-11 12:11:06 +00001411- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001412 return a list or None rather than a custom object.
1413
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001414- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00001437- Issue 3602: Moved test.test_support.catch_warning() to
1438 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1439 for catch_warnings() also led to an improvement in the raising of a
1440 DeprecationWarning related to warnings.warn_explicit().
1441
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001442- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001503What's New in Python 2.6 beta 3?
1504================================

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001507
1508Core and Builtins
1509-----------------
1510
Guido van Rossumf8402962008-08-20 15:01:50 +00001511- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1512 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1513 extensions do not automatically benefit from the class attribute
1514 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1515 to their tp_flags field if they care. This is a backwards
1516 compatibility feature; in 3.0, all types will use the cache by
1517 default.
1518
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001519- Keyword arguments can now follow starred arguments. (``f(a, *args,
1520 keyword=23)`` is now valid syntax.)
1521
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001522- ctypes function pointers that are COM methods have a boolean True
1523 value again.
1524
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001525- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1526 by denying s# to parse objects that have a releasebuffer procedure,
1527 and introducing s*.
1528
Georg Brandl1e13ea92008-08-11 09:07:59 +00001529- Issue #3537: Fix an assertion failure when an empty but presized dict
1530 object was stored in the freelist.
1531
Mark Dickinsonb6467572008-08-04 21:30:09 +00001532- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1533 ValueError consistently across platforms.
1534
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001535- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1536 (64bit Unix, for example), unichr() would truncate its argument and return
1537 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1538
Neal Norwitze7d8be82008-07-31 17:17:14 +00001539- Apply security patches from Apple.
1540
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001541- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1542 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1543
Antoine Pitrou92f82162008-07-25 22:22:08 +00001544- Issue #1819: function calls with several named parameters are now on
1545 average 35% faster (as measured by pybench).
1546
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001547- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1548 the python debugger steps into a class statement: the free variables (local
1549 variables defined in an outer scope) would be deleted from the outer scope.
1550
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001551- Issue #2620: Overflow checking when allocating or reallocating memory
1552 was not always being done properly in some python types and extension
1553 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1554 all been updated to perform better checks and places in the code that
1555 would previously leak memory on the error path when such an allocation
1556 failed have been fixed.

1562
Benjamin Petersone977ad42008-08-20 01:42:01 +00001563- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1564 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1565
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001566- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1567 version reported by these tools does not necessarily follow the python
1568 version numbering scheme, so the module is less strict when parsing it.
1569
Nick Coghlanf70385a2008-08-18 12:42:46 +00001570- Issue #2235: Added Py3k warnings for types which will become unhashable
1571 under the stricter __hash__ inheritance rules in 3.0. Several types
1572 which did not meet the rules for hash invariants and were already
1573 unhashable in 3.0 have now been explicitly flagged as unhashable in
1574 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1575 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1576
Brett Cannon88f801d2008-08-18 00:46:22 +00001577- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1578 imported into the module but exposed as part of the module's API.
1579
Brett Cannon7b96f072008-08-18 00:41:11 +00001580- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001584- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1585
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001586- Issue #3575: Incremental decoder's decode function now takes bytearray
1587 by using 's*' instead of 't#'.
1588

1690
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001691- Issue #643841: The language reference now provides more detailed

1698================================
1699
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001700*Release date: 17-Jul-2008*

1703-----------------
1704
Georg Brandl3e483f62008-07-16 22:57:41 +00001705- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1706 its methods now allow for items objects that can be converted to
1707 an integer using operator.index().
1708
Mark Dickinson64b7e502008-07-16 09:40:03 +00001709- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1710 produced a ValueError instead of giving the correct float.
1711
Eric Smitha5fa5a22008-07-16 00:11:49 +00001712- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1713 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1714
Mark Dickinson7103aa42008-07-15 19:08:33 +00001715- Issue #3008: the float type has a new instance method 'float.hex'
1716 and a new class method 'float.fromhex' to convert floating-point
1717 numbers to and from hexadecimal strings, respectively.
1718
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001719- Issue #2235: __hash__ is once again inherited by default. To allow
1720 collections.Hashable to remain meaningful in the presence of the
1721 default hash implementation (object.__hash__), it is now possible
1722 to explicit block inheritance of hash by setting __hash__=None at
1723 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1724 level.
1725
Nick Coghlanb028f502008-07-13 14:52:36 +00001726- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1727 the parent module cannot be found while performing an absolute import.
1728 This means that an incorrectly defined __package__ attribute will
1729 now only prevent relative imports in that module rather than causing
1730 all imports from that module to fail.
1731
Nick Coghlan14ff9942008-07-08 14:21:42 +00001732- Issue #2517: Allow unicode messages in Exceptions again by correctly
1733 bypassing the instance dictionary when looking up __unicode__ on
1734 new-style classes.
1735
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001736- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1737 set to a custom object whose write() method happens to install
1738 another file in sys.stdout.
1739
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001740- Issue #3088: Corrected a race condition in classes derived from
1741 threading.local: the first member set by a thread could be saved in
1742 another thread's dictionary.
1743
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001744- Issue #3004: Minor change to slice.indices(): the start and stop
1745 arguments are now treated identically, making the behaviour easier
1746 to describe and understand. For example, slice(None, -10,
1747 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1748 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1749 10, -1).
1750
Georg Brandl278fc502008-07-19 12:46:12 +00001751- Issue #3219: Calling a function with repeated keyword arguments,
1752 f(a=2, a=23), would not cause a syntax error. This was a regression
1753 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001754
Georg Brandl278fc502008-07-19 12:46:12 +00001755- Issue #2862: Make int and float freelist management consistent with
1756 other freelists. Changes their CompactFreeList apis into
1757 ClearFreeList apis and calls them via gc.collect().

1763 api functions without holding the GIL, which could lead to a fatal
1764 error when they failed.
1765
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001766- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001791- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1792 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001793 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001794 content-length. The problem had been corrected in the 2.4 branch, but never
1795 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001810- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1812
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001813- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl5cc774e2008-06-11 20:28:06 +00002203 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002204
2205 This is controlled by the configure argument ``--with-universal-archs``:
2206
2207 - ``--with-universal-archs=all``: install 4-way universal
2208
2209 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2210
2211 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2212
2213 This option should be used in combination with ``--enable-universalsdk=``.

2266 original Python code has been kept as backup). This will allow for
2267 using the 'warning's machinery in such places as the parser where
2268 use of pure Python code is not possible. Both the ``showarning()``
2269 and ``formatwarning()`` gain an optional 'line' argument which is
2270 not called by default for backwards-compatibility reasons. Setting
2271 ``warnings.showwarning()`` to an implementation that lacks support
2272 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002335- Issue #2550: The approach used by client/server code for obtaining
2336 ports to listen on in network-oriented tests has been refined in an
2337 effort to facilitate running multiple instances of the entire
2338 regression test suite in parallel without issue.
2339 test_support.bind_port() has been fixed such that it will always
2340 return a unique port -- which wasn't always the case with the
2341 previous implementation, especially if socket options had been set
2342 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2343 new implementation of bind_port() will actually raise an exception
2344 if it is passed an AF_INET/SOCK_STREAM socket with either the
2345 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2346 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2347 the socket it's been passed. This currently only applies to
2348 Windows. This option prevents any other sockets from binding to the
2349 host/port we've bound to, thus removing the possibility of the
2350 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2351 when a second SOCK_STREAM socket binds and accepts to a host/port
2352 that's already been bound by another socket. The optional preferred
2353 port parameter to bind_port() has been removed. Under no
2354 circumstances should tests be hard coding ports!
2355
2356 test_support.find_unused_port() has also been introduced, which will
2357 pass a temporary socket object to bind_port() in order to obtain an
2358 unused port. The temporary socket object is then closed and
2359 deleted, and the port is returned. This method should only be used
2360 for obtaining an unused port in order to pass to an external program
2361 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2362 a parameter to a server-oriented class that doesn't give you direct
2363 access to the underlying socket used.
2364
2365 Finally, test_support.HOST has been introduced, which should be used
2366 for the host argument of any relevant socket calls (i.e. bind and
2367 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002368
2369 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002370 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002371 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2372 test_asynchat and test_socket_ssl.
2373
Georg Brandl3ee81df2008-05-17 18:14:43 +00002374 It is now possible for multiple instances of the regression test
2375 suite to run in parallel without issue.

2432 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2433 this case, like normal unicode literals and the 'unicode-escape'
2434 codec.

2642-----------------
2643
Fred Drakea8ee94b2008-03-01 02:45:07 +00002644- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002645 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002650
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002651- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002652 issue 215555 for a discussion.
2653
Eric Smitha73fbe72008-02-23 03:09:44 +00002654- Added the future_builtins module, which contains hex() and oct().
2655 These are the PEP 3127 version of these functions, designed to be
2656 compatible with the hex() and oct() builtins from Python 3.0. They
2657 differ slightly in their output formats from the existing, unchanged
2658 Python 2.6 builtins. The expected usage of the future_builtins
2659 module is:
2660 from future_builtins import hex, oct
2661
Eric Smith7ef40bf2008-02-20 23:34:22 +00002662- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2663 exponents for exponents with absolute value < 100. Follows C99
2664 standard. This is a change on Windows, which would use 3 digits.
2665 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2666 so that any alterations it does to the resulting string will be
2667 available in stringlib/formatter.h (for float.__format__).
2668
Eric Smith5a3c1352008-02-19 13:21:56 +00002669- Implemented PEP 3101, Advanced String Formatting. This adds a new
2670 builtin format(); a format() method for str and unicode; a
2671 __format__() method to object, str, unicode, int, long, float, and
2672 datetime; the class string.Formatter; and the C API
2673 PyObject_Format().
2674
Georg Brandl3ee81df2008-05-17 18:14:43 +00002675- Fixed several potential crashes, all caused by specially crafted
2676 __del__ methods exploiting objects in temporarily inconsistent
2677 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002678
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002679- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002680 prevent a possible crash: an Abstract Base Class would try to access
2681 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002686- Clear all free lists during a gc.collect() of the highest generation
2687 in order to allow pymalloc to free more arenas. Python may give back
2688 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002689
Georg Brandl3ee81df2008-05-17 18:14:43 +00002690- Issue #2045: Fix an infinite recursion triggered when printing a
2691 subclass of collections.defaultdict, if its default_factory is set
2692 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002700- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2701 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002702 to compact the internal free lists of pre-allocted ints and floats.
2703
Georg Brandl3ee81df2008-05-17 18:14:43 +00002704- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2705 calls. Python expected the return type int but the fork familie
2706 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002707
Georg Brandl3ee81df2008-05-17 18:14:43 +00002708- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00002720- Patch #1473257: generator objects gain a gi_code attribute. This is
2721 the same object as the func_code attribute of the function that
2722 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002723
Georg Brandl3ee81df2008-05-17 18:14:43 +00002724- Issue #1920: "while 0" statements were completely removed by the
2725 compiler, even in the presence of an "else" clause, which is
2726 supposed to be run when the condition is false. Now the compiler
2727 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002728
Guido van Rossumeead05f2008-01-24 18:21:02 +00002729- A few crashers fixed: weakref_in_del.py (issue #1377858);
2730 loosing_dict_ref.py (issue #1303614, test67.py);
2731 borrowed_ref_[34].py (not in tracker).
2732
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002733- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002734 suppressed while an extension is loaded by calling SetErrorMode in
2735 dynload_win.c. The error is still reported properly.
2736
Georg Brandl3ee81df2008-05-17 18:14:43 +00002737- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002738 several extension methods and modules do not work without unicode
2739 support.
2740
Georg Brandl26543b12008-01-21 18:36:51 +00002741- Issue #1882: when compiling code from a string, encoding cookies in the

2745
Georg Brandl6caad7d2008-01-26 14:19:22 +00002746- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002747 added.
2748
Christian Heimesc94e2b52008-01-14 04:13:37 +00002749- sys.float_info / PyFloat_GetInfo: The floating point information
2750 object was converted from a dict to a specialized structseq object.
2751
Georg Brandl3ee81df2008-05-17 18:14:43 +00002752- Patch #1816: Added sys.flags structseq. It exposes the status of
2753 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002754
Georg Brandl3ee81df2008-05-17 18:14:43 +00002755- Objects/structseq.c: Implemented new structseq representation. The
2756 patch makes structseqs (e.g. the return value of os.stat) more
2757 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002758
Georg Brandl3ee81df2008-05-17 18:14:43 +00002759- Patch #1700288: added a type attribute cache that caches method
2760 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002761
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002762- Bug #1776: __import__() no longer accepts filenames on any platform.
2763 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002764

2768 envvar and sys.dont_write_bytecode attribute. All these can be set
2769 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002770
Georg Brandl3ee81df2008-05-17 18:14:43 +00002771- Improve some exception messages when Windows fails to load an
2772 extension module. Now we get for example '%1 is not a valid Win32
2773 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002774

Christian Heimes0a8143f2007-12-18 23:22:54 +00002780- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002781 and INF. float("nan"), float("inf") and float("-inf") now work on
2782 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002783
Georg Brandl3ee81df2008-05-17 18:14:43 +00002784- Compiler now generates simpler and faster code for dictionary
2785 literals. The oparg for BUILD_MAP now indicates an estimated
2786 dictionary size. There is a new opcode, STORE_MAP, for adding
2787 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002816- Patch #1739468: Directories and zipfiles containing a __main__.py
2817 file can now be directly executed by passing their name to the
2818 interpreter. The directory/zipfile is automatically inserted as the
2819 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002821- Issue #1265: Fix a problem with sys.settrace, if the tracing
2822 function uses a generator expression when at the same time the
2823 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002824
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002825- sets and frozensets now have an isdisjoint() method.
2826

2828
Neal Norwitz44f326e2007-10-05 05:29:17 +00002829- Fix warnings found by the new version of the Coverity checker.
2830
Georg Brandl3ee81df2008-05-17 18:14:43 +00002831- The enumerate() builtin function is no longer bounded to sequences
2832 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2833 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002834
Georg Brandl3ee81df2008-05-17 18:14:43 +00002835- Issue #1686386: Tuple's tp_repr did not take into account the
2836 possibility of having a self-referential tuple, which is possible
2837 from C code. Nor did object's tp_str consider that a type's tp_str
2838 could do something that could lead to an inifinite recursion.
2839 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2840 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002841
Georg Brandl3ee81df2008-05-17 18:14:43 +00002842- Issue #1164: It was possible to trigger deadlock when using the
2843 'print' statement to write to a file since the GIL was not released
2844 as needed. Now PyObject_Print() does the right thing along with
2845 various tp_print implementations of the built-in types and those in
2846 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002847
Georg Brandl3ee81df2008-05-17 18:14:43 +00002848- Issue #1147: Exceptions were directly allowing string exceptions in

2850 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002851
Georg Brandl3ee81df2008-05-17 18:14:43 +00002852- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00002854
Brett Cannon1e534b52007-09-07 04:18:30 +00002855- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002856 PyObject_Call() never calling back out to Python code to trigger
2857 recursion depth updates/checks. Required the creation of a static
2858 RuntimeError instance in case normalizing an exception put the
2859 recursion check value past its limit. Fixes crashers
2860 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002861

Neal Norwitz0ac60192007-05-27 04:08:54 +00002875- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002876 __*__ attributes. (Some already existed, e.g., __doc__ and
2877 __name__.)

2883 calls.
2884
Collin Winter62903052007-05-18 23:11:24 +00002885- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002886 "except E as target:". This is to provide forwards compatibility
2887 with Python 3.0.

2893
Vinay Sajip8549ce32007-05-06 17:53:37 +00002894- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002895 setting a plain string, ie don't expand to single letter identifiers.
2896
Raymond Hettinger13936692007-04-11 18:40:58 +00002897- Request #1191699: Slices can now be pickled.
2898
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002899- Request #1193128: str.translate() now allows a None argument for

2901 remaining characters.
2902
Georg Brandl5cb76c12007-03-21 09:00:39 +00002903- Patch #1682205: a TypeError while unpacking an iterable is no longer
2904 masked by a generic one with the message "unpack non-sequence".
2905
Neal Norwitzaa754b72007-03-21 06:39:48 +00002906- Remove unused file Python/fmod.c.
2907
Guido van Rossum143b5642007-03-23 04:58:42 +00002908- Bug #1683368: The object.__init__() and object.__new__() methods are
2909 now stricter in rejecting excess arguments. The only time when
2910 either allows excess arguments is when it is not overridden and the
2911 other one is. For backwards compatibility, when both are
2912 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002913 warning later). Also, type.__init__() insists on the same signature
2914 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002916- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2917 object to complex using its __complex__() method before falling back
2918 to the __float__() method. Therefore, the functions in the cmath
2919 module now can operate on objects that define a __complex__()
2920 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002942 its argument, if it exists. If not, it will work like before. This
2943 allows customizing the output of dir() in the presence of a
2944 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00002956- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00003026- Bug #1545497: when given an explicit base, int() did ignore NULs
3027 embedded in the string to convert.
3028
Georg Brandl846f73a2006-10-08 07:11:54 +00003029- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00003059- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003077 generator expressions (x for x, in ... ) works again. Fixing this
3078 problem required changing the .pyc magic number. This means that
3079 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003994 time so that opening a database previously created with the DB_DUP
3995 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3996 opens. Specifically: dictionary assignment to a DB object will
3997 replace all values for a given key when the database allows
3998 duplicate values. DB users should use DB.put(k, v) when they want
3999 to store duplicates; not DB[k] = v.

4006 characters with ASCII value less than 32. Also, it correctly quotes
4007 dots only if they occur on a single line, as opposed to the previous
4008 behavior of quoting dots if they are the second character of any
4009 line.
