Tarek Ziadé06426fc2010-01-11 22:54:57 +0000130- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since

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

214 than the current precision) in shift and rotate.
215
R. David Murray7034db32009-10-27 23:39:06 +0000216- Issue #7082: When falling back to the MIME 'name' parameter, the

992 302 conformant loader) will now work correctly in most cases (they
993 are still subject to the constraints that exist for all code running

1153What's New in Python 2.6.1
1154==========================
1155
1156*Release date: 04-Dec-2008*
1157
1158Core and Builtins
1159-----------------
1160
1161- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1162 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1163 instead of throwing a MemoryError.
1164
1165- Issue #4367: Python would segfault during compiling when the unicodedata
1166 module couldn't be imported and \N escapes were present.
1167
1168- Issue #4348: Some bytearray methods returned that didn't cause any change to
1169 the bytearray, returned the same bytearray instead of a copy.
1170
1171- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1172
1173- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1174
1175- Issue #4048: The parser module now correctly validates relative imports.
1176
1177- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1178 exec statement.
1179
1180- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1181 method does not return iterators for the 4th and 5th items.
1182
1183- Issue #4209: Enabling unicode_literals and the print_function in the same
1184 __future__ import didn't work.
1185
1186- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1187 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1188 really executed because I cannot move to such directory on win2k)
1189
1190- Issue #4069: When set.remove(element) is used with a set element, the element
1191 is temporarily replaced with an equivalent frozenset. But the eventual
1192 KeyError would always report the empty frozenset([]) as the missing key. Now
1193 it correctly refers to the initial element.
1194
1195- Fixed C99 style comments in several files. Python is now C89 compatible
1196 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001343- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1344
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001345- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1346 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1347 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1348 ``printf`` function, whereas PyString_FromFormat has an independent
1349 implementation and uses "%zd" on all platforms for size_t values.
1350 This makes a difference on win64, where ``printf`` needs "%Id" to display
1351 64bit values.
1352
Benjamin Peterson97179b02008-09-09 20:55:01 +00001353- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1354 error.
1355
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001356- Issue #3777: long() applied to a float object now always return a long
1357 object; previously an int would be returned for small values. the __long__
1358 method is allowed to return either an int or a long, but the behaviour of
1359 float objects should not change to respect backward compatibility.
1360
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001361- Issue #3751: str.rpartition would perform a left-partition when called with
1362 a unicode argument.
1363
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001364- Issue #3683: Fix compilation when --without-threads is given.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001366- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001367 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001368 was correctly parsed but parsing of subsequent arguments failed.
1369
Vinay Sajip35e3b032008-09-01 14:33:59 +00001370- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001371 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1372 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1373 when given a tuple of classes as second argument, were looking up
1374 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1375 type object.
1376
Neal Norwitz18aa3882008-08-24 05:04:52 +00001377- Fix crashes on memory allocation failure found with failmalloc.
1378
1379- Fix memory leaks found with valgrind and update suppressions file.
1380
1381- Fix compiler warnings in opt mode which would lead to invalid memory reads.

1446 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1447 for catch_warnings() also led to an improvement in the raising of a
1448 DeprecationWarning related to warnings.warn_explicit().

1516Core and Builtins
1517-----------------
1518
Guido van Rossumf8402962008-08-20 15:01:50 +00001519- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1520 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1521 extensions do not automatically benefit from the class attribute
1522 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1523 to their tp_flags field if they care. This is a backwards
1524 compatibility feature; in 3.0, all types will use the cache by
1525 default.
1526
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001527- Keyword arguments can now follow starred arguments. (``f(a, *args,
1528 keyword=23)`` is now valid syntax.)
1529
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001530- ctypes function pointers that are COM methods have a boolean True
1531 value again.
1532
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001533- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1534 by denying s# to parse objects that have a releasebuffer procedure,
1535 and introducing s*.
1536
Georg Brandl1e13ea92008-08-11 09:07:59 +00001537- Issue #3537: Fix an assertion failure when an empty but presized dict
1538 object was stored in the freelist.
1539
Mark Dickinsonb6467572008-08-04 21:30:09 +00001540- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1541 ValueError consistently across platforms.
1542
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001543- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1544 (64bit Unix, for example), unichr() would truncate its argument and return
1545 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1546
Neal Norwitze7d8be82008-07-31 17:17:14 +00001547- Apply security patches from Apple.
1548
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001549- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1550 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1551
Antoine Pitrou92f82162008-07-25 22:22:08 +00001552- Issue #1819: function calls with several named parameters are now on
1553 average 35% faster (as measured by pybench).
1554
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001555- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1556 the python debugger steps into a class statement: the free variables (local
1557 variables defined in an outer scope) would be deleted from the outer scope.
1558
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001559- Issue #2620: Overflow checking when allocating or reallocating memory
1560 was not always being done properly in some python types and extension
1561 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1562 all been updated to perform better checks and places in the code that
1563 would previously leak memory on the error path when such an allocation
1564 failed have been fixed.

1570
Benjamin Petersone977ad42008-08-20 01:42:01 +00001571- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1572 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1573
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001574- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1575 version reported by these tools does not necessarily follow the python
1576 version numbering scheme, so the module is less strict when parsing it.
1577
Nick Coghlanf70385a2008-08-18 12:42:46 +00001578- Issue #2235: Added Py3k warnings for types which will become unhashable
1579 under the stricter __hash__ inheritance rules in 3.0. Several types
1580 which did not meet the rules for hash invariants and were already
1581 unhashable in 3.0 have now been explicitly flagged as unhashable in
1582 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1583 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1584
Brett Cannon88f801d2008-08-18 00:46:22 +00001585- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1586 imported into the module but exposed as part of the module's API.
1587

1698
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001699- Issue #643841: The language reference now provides more detailed

1711-----------------
1712
Georg Brandl3e483f62008-07-16 22:57:41 +00001713- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1714 its methods now allow for items objects that can be converted to
1715 an integer using operator.index().
1716
Mark Dickinson64b7e502008-07-16 09:40:03 +00001717- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1718 produced a ValueError instead of giving the correct float.
1719
Eric Smitha5fa5a22008-07-16 00:11:49 +00001720- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1721 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1722
Mark Dickinson7103aa42008-07-15 19:08:33 +00001723- Issue #3008: the float type has a new instance method 'float.hex'
1724 and a new class method 'float.fromhex' to convert floating-point
1725 numbers to and from hexadecimal strings, respectively.
1726
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001727- Issue #2235: __hash__ is once again inherited by default. To allow
1728 collections.Hashable to remain meaningful in the presence of the
1729 default hash implementation (object.__hash__), it is now possible
1730 to explicit block inheritance of hash by setting __hash__=None at
1731 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1732 level.
1733
Nick Coghlanb028f502008-07-13 14:52:36 +00001734- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1735 the parent module cannot be found while performing an absolute import.
1736 This means that an incorrectly defined __package__ attribute will
1737 now only prevent relative imports in that module rather than causing
1738 all imports from that module to fail.
1739
Nick Coghlan14ff9942008-07-08 14:21:42 +00001740- Issue #2517: Allow unicode messages in Exceptions again by correctly

1750 another thread's dictionary.
1751
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001752- Issue #3004: Minor change to slice.indices(): the start and stop
1753 arguments are now treated identically, making the behaviour easier
1754 to describe and understand. For example, slice(None, -10,
1755 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1756 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1757 10, -1).
1758
Georg Brandl278fc502008-07-19 12:46:12 +00001759- Issue #3219: Calling a function with repeated keyword arguments,
1760 f(a=2, a=23), would not cause a syntax error. This was a regression
1761 from 2.4 caused by the switch to the new compiler.

1772 error when they failed.
1773
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001774- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1800 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001801 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001802 content-length. The problem had been corrected in the 2.4 branch, but never

2208
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002209- On MacOS X it is now possible to install the framework in 64-bit
2210 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002211 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002212
2213 This is controlled by the configure argument ``--with-universal-archs``:
2214
2215 - ``--with-universal-archs=all``: install 4-way universal
2216
2217 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2218
2219 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2220
2221 This option should be used in combination with ``--enable-universalsdk=``.
2222
2223 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 +00002273- Issue #1631171: Re-implement the 'warnings' module in C (the
2274 original Python code has been kept as backup). This will allow for
2275 using the 'warning's machinery in such places as the parser where
2276 use of pure Python code is not possible. Both the ``showarning()``
2277 and ``formatwarning()`` gain an optional 'line' argument which is
2278 not called by default for backwards-compatibility reasons. Setting
2279 ``warnings.showwarning()`` to an implementation that lacks support
2280 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002343- Issue #2550: The approach used by client/server code for obtaining
2344 ports to listen on in network-oriented tests has been refined in an
2345 effort to facilitate running multiple instances of the entire
2346 regression test suite in parallel without issue.
2347 test_support.bind_port() has been fixed such that it will always
2348 return a unique port -- which wasn't always the case with the
2349 previous implementation, especially if socket options had been set
2350 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2351 new implementation of bind_port() will actually raise an exception
2352 if it is passed an AF_INET/SOCK_STREAM socket with either the
2353 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2354 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2355 the socket it's been passed. This currently only applies to
2356 Windows. This option prevents any other sockets from binding to the
2357 host/port we've bound to, thus removing the possibility of the
2358 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2359 when a second SOCK_STREAM socket binds and accepts to a host/port
2360 that's already been bound by another socket. The optional preferred
2361 port parameter to bind_port() has been removed. Under no
2362 circumstances should tests be hard coding ports!
2363
2364 test_support.find_unused_port() has also been introduced, which will
2365 pass a temporary socket object to bind_port() in order to obtain an
2366 unused port. The temporary socket object is then closed and
2367 deleted, and the port is returned. This method should only be used
2368 for obtaining an unused port in order to pass to an external program
2369 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2370 a parameter to a server-oriented class that doesn't give you direct
2371 access to the underlying socket used.
2372
2373 Finally, test_support.HOST has been introduced, which should be used
2374 for the host argument of any relevant socket calls (i.e. bind and
2375 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002376
2377 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002378 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002379 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2380 test_asynchat and test_socket_ssl.
2381
Georg Brandl3ee81df2008-05-17 18:14:43 +00002382 It is now possible for multiple instances of the regression test
2383 suite to run in parallel without issue.

2436
Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00002437- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00002438 \Uxxxxxxxx did not accept values outside the Basic Multilingual
2439 Plane. This affected raw unicode literals and the
2440 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2441 this case, like normal unicode literals and the 'unicode-escape'
2442 codec.

2651
Fred Drakea8ee94b2008-03-01 02:45:07 +00002652- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002653 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002658
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002659- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002660 issue 215555 for a discussion.
2661
Eric Smitha73fbe72008-02-23 03:09:44 +00002662- Added the future_builtins module, which contains hex() and oct().
2663 These are the PEP 3127 version of these functions, designed to be
2664 compatible with the hex() and oct() builtins from Python 3.0. They
2665 differ slightly in their output formats from the existing, unchanged
2666 Python 2.6 builtins. The expected usage of the future_builtins
2667 module is:
2668 from future_builtins import hex, oct
2669
Eric Smith7ef40bf2008-02-20 23:34:22 +00002670- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2671 exponents for exponents with absolute value < 100. Follows C99
2672 standard. This is a change on Windows, which would use 3 digits.
2673 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2674 so that any alterations it does to the resulting string will be
2675 available in stringlib/formatter.h (for float.__format__).
2676
Eric Smith5a3c1352008-02-19 13:21:56 +00002677- Implemented PEP 3101, Advanced String Formatting. This adds a new
2678 builtin format(); a format() method for str and unicode; a
2679 __format__() method to object, str, unicode, int, long, float, and
2680 datetime; the class string.Formatter; and the C API
2681 PyObject_Format().
2682
Georg Brandl3ee81df2008-05-17 18:14:43 +00002683- Fixed several potential crashes, all caused by specially crafted
2684 __del__ methods exploiting objects in temporarily inconsistent
2685 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002686
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002687- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002688 prevent a possible crash: an Abstract Base Class would try to access
2689 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002690

Georg Brandl3ee81df2008-05-17 18:14:43 +00002694- Clear all free lists during a gc.collect() of the highest generation
2695 in order to allow pymalloc to free more arenas. Python may give back
2696 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002697
Georg Brandl3ee81df2008-05-17 18:14:43 +00002698- Issue #2045: Fix an infinite recursion triggered when printing a
2699 subclass of collections.defaultdict, if its default_factory is set

Georg Brandl3ee81df2008-05-17 18:14:43 +00002708- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2709 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002710 to compact the internal free lists of pre-allocted ints and floats.
2711
Georg Brandl3ee81df2008-05-17 18:14:43 +00002712- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2713 calls. Python expected the return type int but the fork familie
2714 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002715
Georg Brandl3ee81df2008-05-17 18:14:43 +00002716- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00002728- Patch #1473257: generator objects gain a gi_code attribute. This is
2729 the same object as the func_code attribute of the function that
2730 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002731
Georg Brandl3ee81df2008-05-17 18:14:43 +00002732- Issue #1920: "while 0" statements were completely removed by the
2733 compiler, even in the presence of an "else" clause, which is
2734 supposed to be run when the condition is false. Now the compiler
2735 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002736
Guido van Rossumeead05f2008-01-24 18:21:02 +00002737- A few crashers fixed: weakref_in_del.py (issue #1377858);
2738 loosing_dict_ref.py (issue #1303614, test67.py);
2739 borrowed_ref_[34].py (not in tracker).
2740
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002741- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002742 suppressed while an extension is loaded by calling SetErrorMode in
2743 dynload_win.c. The error is still reported properly.
2744
Georg Brandl3ee81df2008-05-17 18:14:43 +00002745- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002746 several extension methods and modules do not work without unicode
2747 support.
2748
Georg Brandl26543b12008-01-21 18:36:51 +00002749- Issue #1882: when compiling code from a string, encoding cookies in the

2751
Georg Brandl14404b62008-01-19 19:27:05 +00002752- Issue #1679: "0x" was taken as a valid integer literal.
2753
Georg Brandl6caad7d2008-01-26 14:19:22 +00002754- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002755 added.
2756
Christian Heimesc94e2b52008-01-14 04:13:37 +00002757- sys.float_info / PyFloat_GetInfo: The floating point information
2758 object was converted from a dict to a specialized structseq object.
2759
Georg Brandl3ee81df2008-05-17 18:14:43 +00002760- Patch #1816: Added sys.flags structseq. It exposes the status of
2761 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002762
Georg Brandl3ee81df2008-05-17 18:14:43 +00002763- Objects/structseq.c: Implemented new structseq representation. The
2764 patch makes structseqs (e.g. the return value of os.stat) more
2765 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002766
Georg Brandl3ee81df2008-05-17 18:14:43 +00002767- Patch #1700288: added a type attribute cache that caches method
2768 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002769
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002770- Bug #1776: __import__() no longer accepts filenames on any platform.
2771 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002772
Georg Brandlaed6c662008-01-07 17:25:53 +00002773- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2774

2776 envvar and sys.dont_write_bytecode attribute. All these can be set
2777 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002778
Georg Brandl3ee81df2008-05-17 18:14:43 +00002779- Improve some exception messages when Windows fails to load an
2780 extension module. Now we get for example '%1 is not a valid Win32
2781 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002782

Christian Heimes0a8143f2007-12-18 23:22:54 +00002788- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002789 and INF. float("nan"), float("inf") and float("-inf") now work on
2790 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002791
Georg Brandl3ee81df2008-05-17 18:14:43 +00002792- Compiler now generates simpler and faster code for dictionary
2793 literals. The oparg for BUILD_MAP now indicates an estimated
2794 dictionary size. There is a new opcode, STORE_MAP, for adding
2795 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002824- Patch #1739468: Directories and zipfiles containing a __main__.py
2825 file can now be directly executed by passing their name to the
2826 interpreter. The directory/zipfile is automatically inserted as the
2827 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002828
Georg Brandl3ee81df2008-05-17 18:14:43 +00002829- Issue #1265: Fix a problem with sys.settrace, if the tracing
2830 function uses a generator expression when at the same time the
2831 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002832
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002833- sets and frozensets now have an isdisjoint() method.
2834

2838
Georg Brandl3ee81df2008-05-17 18:14:43 +00002839- The enumerate() builtin function is no longer bounded to sequences
2840 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2841 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002842
Georg Brandl3ee81df2008-05-17 18:14:43 +00002843- Issue #1686386: Tuple's tp_repr did not take into account the
2844 possibility of having a self-referential tuple, which is possible
2845 from C code. Nor did object's tp_str consider that a type's tp_str
2846 could do something that could lead to an inifinite recursion.
2847 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2848 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002849
Georg Brandl3ee81df2008-05-17 18:14:43 +00002850- Issue #1164: It was possible to trigger deadlock when using the
2851 'print' statement to write to a file since the GIL was not released
2852 as needed. Now PyObject_Print() does the right thing along with
2853 various tp_print implementations of the built-in types and those in
2854 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002855
Georg Brandl3ee81df2008-05-17 18:14:43 +00002856- Issue #1147: Exceptions were directly allowing string exceptions in

2858 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002859

Brett Cannon1e534b52007-09-07 04:18:30 +00002863- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002864 PyObject_Call() never calling back out to Python code to trigger
2865 recursion depth updates/checks. Required the creation of a static
2866 RuntimeError instance in case normalizing an exception put the
2867 recursion check value past its limit. Fixes crashers
2868 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002869

Neal Norwitz0ac60192007-05-27 04:08:54 +00002883- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002884 __*__ attributes. (Some already existed, e.g., __doc__ and
2885 __name__.)

2891 calls.
2892
Collin Winter62903052007-05-18 23:11:24 +00002893- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002894 "except E as target:". This is to provide forwards compatibility
2895 with Python 3.0.

2901
Vinay Sajip8549ce32007-05-06 17:53:37 +00002902- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002903 setting a plain string, ie don't expand to single letter identifiers.
2904
Raymond Hettinger13936692007-04-11 18:40:58 +00002905- Request #1191699: Slices can now be pickled.
2906
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002907- Request #1193128: str.translate() now allows a None argument for

2909 remaining characters.
2910
Georg Brandl5cb76c12007-03-21 09:00:39 +00002911- Patch #1682205: a TypeError while unpacking an iterable is no longer
2912 masked by a generic one with the message "unpack non-sequence".
2913
Neal Norwitzaa754b72007-03-21 06:39:48 +00002914- Remove unused file Python/fmod.c.
2915
Guido van Rossum143b5642007-03-23 04:58:42 +00002916- Bug #1683368: The object.__init__() and object.__new__() methods are
2917 now stricter in rejecting excess arguments. The only time when
2918 either allows excess arguments is when it is not overridden and the
2919 other one is. For backwards compatibility, when both are
2920 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002921 warning later). Also, type.__init__() insists on the same signature
2922 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002924- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2925 object to complex using its __complex__() method before falling back
2926 to the __float__() method. Therefore, the functions in the cmath
2927 module now can operate on objects that define a __complex__()
2928 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002950 its argument, if it exists. If not, it will work like before. This
2951 allows customizing the output of dir() in the presence of a
2952 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00002964- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002965 makes the filenames the warning module prints much more sensible
2966 when a PYTHONSTARTUP file is used.

Georg Brandl2c1375c2006-10-12 11:27:59 +00003034- Bug #1545497: when given an explicit base, int() did ignore NULs
3035 embedded in the string to convert.
3036
Georg Brandl846f73a2006-10-08 07:11:54 +00003037- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003085 generator expressions (x for x, in ... ) works again. Fixing this
3086 problem required changing the .pyc magic number. This means that
3087 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003894- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3895 with RFC 3207 and forgets any knowledge obtained from the server not
3896 obtained from the TLS negotiation itself. Patch contributed by Bill
3897 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003899- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003900 that the SMTP.starttls() caller no longer needs to call ehlo()
3901 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003902 does not claim to support starttls. Adds the
3903 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00004002 time so that opening a database previously created with the DB_DUP
4003 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4004 opens. Specifically: dictionary assignment to a DB object will
4005 replace all values for a given key when the database allows
4006 duplicate values. DB users should use DB.put(k, v) when they want
4007 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004008

4014 characters with ASCII value less than 32. Also, it correctly quotes
4015 dots only if they occur on a single line, as opposed to the previous
4016 behavior of quoting dots if they are the second character of any
4017 line.
