Tarek Ziadé06426fc2010-01-11 22:54:57 +0000132- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since

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

216 than the current precision) in shift and rotate.
217
R. David Murray7034db32009-10-27 23:39:06 +0000218- Issue #7082: When falling back to the MIME 'name' parameter, the

1003- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1004 302 conformant loader) will now work correctly in most cases (they
1005 are still subject to the constraints that exist for all code running
1006 from inside a module loaded via a PEP 302 loader and attempting to

1165What's New in Python 2.6.1
1166==========================
1167
1168*Release date: 04-Dec-2008*
1169
1170Core and Builtins
1171-----------------
1172
1173- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1174 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1175 instead of throwing a MemoryError.
1176
1177- Issue #4367: Python would segfault during compiling when the unicodedata
1178 module couldn't be imported and \N escapes were present.
1179
1180- Issue #4348: Some bytearray methods returned that didn't cause any change to
1181 the bytearray, returned the same bytearray instead of a copy.
1182
1183- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1184
1185- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1186
1187- Issue #4048: The parser module now correctly validates relative imports.
1188
1189- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1190 exec statement.
1191
1192- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1193 method does not return iterators for the 4th and 5th items.
1194
1195- Issue #4209: Enabling unicode_literals and the print_function in the same
1196 __future__ import didn't work.
1197
1198- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1199 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1200 really executed because I cannot move to such directory on win2k)
1201
1202- Issue #4069: When set.remove(element) is used with a set element, the element
1203 is temporarily replaced with an equivalent frozenset. But the eventual
1204 KeyError would always report the empty frozenset([]) as the missing key. Now
1205 it correctly refers to the initial element.
1206
1207- Fixed C99 style comments in several files. Python is now C89 compatible
1208 again.

1354
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001355- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1356
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001357- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1358 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1359 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1360 ``printf`` function, whereas PyString_FromFormat has an independent
1361 implementation and uses "%zd" on all platforms for size_t values.
1362 This makes a difference on win64, where ``printf`` needs "%Id" to display
1363 64bit values.
1364
Benjamin Peterson97179b02008-09-09 20:55:01 +00001365- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1366 error.
1367
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001368- Issue #3777: long() applied to a float object now always return a long
1369 object; previously an int would be returned for small values. the __long__
1370 method is allowed to return either an int or a long, but the behaviour of
1371 float objects should not change to respect backward compatibility.
1372
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001373- Issue #3751: str.rpartition would perform a left-partition when called with
1374 a unicode argument.
1375
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001376- Issue #3683: Fix compilation when --without-threads is given.
1377
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001378- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001379 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001380 was correctly parsed but parsing of subsequent arguments failed.
1381
Vinay Sajip35e3b032008-09-01 14:33:59 +00001382- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001383 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1384 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1385 when given a tuple of classes as second argument, were looking up
1386 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1387 type object.
1388
Neal Norwitz18aa3882008-08-24 05:04:52 +00001389- Fix crashes on memory allocation failure found with failmalloc.
1390
1391- Fix memory leaks found with valgrind and update suppressions file.
1392
1393- Fix compiler warnings in opt mode which would lead to invalid memory reads.

Christian Heimes7d4c3172008-08-22 19:47:25 +00001397- Silenced another compiler warning about a used but not defined
1398 function 'stringlib_contains_obj'.

1404 library targets in the Makefile.
1405
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001406- Issue #1204: The configure script now tests for additional libraries

1427 with statements, or when the methods are invoked in the wrong order.
1428

Nick Coghland2e09382008-09-11 12:11:06 +00001431- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001432 return a list or None rather than a custom object.

1458 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1459 for catch_warnings() also led to an improvement in the raising of a
1460 DeprecationWarning related to warnings.warn_explicit().
1461

1529-----------------
1530
Guido van Rossumf8402962008-08-20 15:01:50 +00001531- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1532 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1533 extensions do not automatically benefit from the class attribute
1534 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1535 to their tp_flags field if they care. This is a backwards
1536 compatibility feature; in 3.0, all types will use the cache by
1537 default.
1538
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001539- Keyword arguments can now follow starred arguments. (``f(a, *args,
1540 keyword=23)`` is now valid syntax.)
1541
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001542- ctypes function pointers that are COM methods have a boolean True
1543 value again.
1544
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001545- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1546 by denying s# to parse objects that have a releasebuffer procedure,
1547 and introducing s*.
1548
Georg Brandl1e13ea92008-08-11 09:07:59 +00001549- Issue #3537: Fix an assertion failure when an empty but presized dict
1550 object was stored in the freelist.
1551
Mark Dickinsonb6467572008-08-04 21:30:09 +00001552- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1553 ValueError consistently across platforms.
1554
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001555- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1556 (64bit Unix, for example), unichr() would truncate its argument and return
1557 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1558
Neal Norwitze7d8be82008-07-31 17:17:14 +00001559- Apply security patches from Apple.
1560
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001561- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1562 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1563
Antoine Pitrou92f82162008-07-25 22:22:08 +00001564- Issue #1819: function calls with several named parameters are now on
1565 average 35% faster (as measured by pybench).
1566
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001567- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1568 the python debugger steps into a class statement: the free variables (local
1569 variables defined in an outer scope) would be deleted from the outer scope.
1570
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001571- Issue #2620: Overflow checking when allocating or reallocating memory
1572 was not always being done properly in some python types and extension
1573 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1574 all been updated to perform better checks and places in the code that
1575 would previously leak memory on the error path when such an allocation
1576 failed have been fixed.

1582
Benjamin Petersone977ad42008-08-20 01:42:01 +00001583- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1584 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1585
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001586- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1587 version reported by these tools does not necessarily follow the python
1588 version numbering scheme, so the module is less strict when parsing it.
1589
Nick Coghlanf70385a2008-08-18 12:42:46 +00001590- Issue #2235: Added Py3k warnings for types which will become unhashable
1591 under the stricter __hash__ inheritance rules in 3.0. Several types

Antoine Pitroude781a42008-08-09 12:43:23 +00001666 asking for a specific length. This problem only affected files opened

1710
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001711- Issue #643841: The language reference now provides more detailed

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001720*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001722Core and Builtins
1723-----------------
1724
Georg Brandl3e483f62008-07-16 22:57:41 +00001725- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1726 its methods now allow for items objects that can be converted to
1727 an integer using operator.index().
1728
Mark Dickinson64b7e502008-07-16 09:40:03 +00001729- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1730 produced a ValueError instead of giving the correct float.
1731
Eric Smitha5fa5a22008-07-16 00:11:49 +00001732- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1733 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1734
Mark Dickinson7103aa42008-07-15 19:08:33 +00001735- Issue #3008: the float type has a new instance method 'float.hex'
1736 and a new class method 'float.fromhex' to convert floating-point
1737 numbers to and from hexadecimal strings, respectively.
1738
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001739- Issue #2235: __hash__ is once again inherited by default. To allow
1740 collections.Hashable to remain meaningful in the presence of the
1741 default hash implementation (object.__hash__), it is now possible
1742 to explicit block inheritance of hash by setting __hash__=None at
1743 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1744 level.
1745
Nick Coghlanb028f502008-07-13 14:52:36 +00001746- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1747 the parent module cannot be found while performing an absolute import.
1748 This means that an incorrectly defined __package__ attribute will
1749 now only prevent relative imports in that module rather than causing
1750 all imports from that module to fail.
1751
Nick Coghlan14ff9942008-07-08 14:21:42 +00001752- Issue #2517: Allow unicode messages in Exceptions again by correctly
1753 bypassing the instance dictionary when looking up __unicode__ on
1754 new-style classes.
1755

1757 set to a custom object whose write() method happens to install
1758 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001760- Issue #3088: Corrected a race condition in classes derived from
1761 threading.local: the first member set by a thread could be saved in
1762 another thread's dictionary.
1763
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001764- Issue #3004: Minor change to slice.indices(): the start and stop
1765 arguments are now treated identically, making the behaviour easier
1766 to describe and understand. For example, slice(None, -10,
1767 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1768 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1769 10, -1).
1770
Georg Brandl278fc502008-07-19 12:46:12 +00001771- Issue #3219: Calling a function with repeated keyword arguments,
1772 f(a=2, a=23), would not cause a syntax error. This was a regression
1773 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001774
Georg Brandl278fc502008-07-19 12:46:12 +00001775- Issue #2862: Make int and float freelist management consistent with
1776 other freelists. Changes their CompactFreeList apis into

1783 api functions without holding the GIL, which could lead to a fatal
1784 error when they failed.
1785
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001786- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001811- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1812 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001813 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001814 content-length. The problem had been corrected in the 2.4 branch, but never
1815 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001830- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Ronald Oussoren5640ce22008-06-05 12:58:24 +00002221- On MacOS X it is now possible to install the framework in 64-bit
2222 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002223 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002224
2225 This is controlled by the configure argument ``--with-universal-archs``:
2226
2227 - ``--with-universal-archs=all``: install 4-way universal
2228
2229 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2230
2231 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2232
2233 This option should be used in combination with ``--enable-universalsdk=``.
2234
2235 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 +00002285- Issue #1631171: Re-implement the 'warnings' module in C (the
2286 original Python code has been kept as backup). This will allow for
2287 using the 'warning's machinery in such places as the parser where
2288 use of pure Python code is not possible. Both the ``showarning()``
2289 and ``formatwarning()`` gain an optional 'line' argument which is
2290 not called by default for backwards-compatibility reasons. Setting
2291 ``warnings.showwarning()`` to an implementation that lacks support
2292 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002355- Issue #2550: The approach used by client/server code for obtaining
2356 ports to listen on in network-oriented tests has been refined in an
2357 effort to facilitate running multiple instances of the entire
2358 regression test suite in parallel without issue.
2359 test_support.bind_port() has been fixed such that it will always
2360 return a unique port -- which wasn't always the case with the
2361 previous implementation, especially if socket options had been set
2362 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2363 new implementation of bind_port() will actually raise an exception
2364 if it is passed an AF_INET/SOCK_STREAM socket with either the
2365 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2366 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2367 the socket it's been passed. This currently only applies to
2368 Windows. This option prevents any other sockets from binding to the
2369 host/port we've bound to, thus removing the possibility of the
2370 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2371 when a second SOCK_STREAM socket binds and accepts to a host/port
2372 that's already been bound by another socket. The optional preferred
2373 port parameter to bind_port() has been removed. Under no
2374 circumstances should tests be hard coding ports!
2375
2376 test_support.find_unused_port() has also been introduced, which will
2377 pass a temporary socket object to bind_port() in order to obtain an
2378 unused port. The temporary socket object is then closed and
2379 deleted, and the port is returned. This method should only be used
2380 for obtaining an unused port in order to pass to an external program
2381 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2382 a parameter to a server-oriented class that doesn't give you direct
2383 access to the underlying socket used.
2384
2385 Finally, test_support.HOST has been introduced, which should be used
2386 for the host argument of any relevant socket calls (i.e. bind and
2387 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002388
2389 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002390 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002391 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2392 test_asynchat and test_socket_ssl.
2393
Georg Brandl3ee81df2008-05-17 18:14:43 +00002394 It is now possible for multiple instances of the regression test
2395 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00002449- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00002450 \Uxxxxxxxx did not accept values outside the Basic Multilingual
2451 Plane. This affected raw unicode literals and the
2452 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2453 this case, like normal unicode literals and the 'unicode-escape'
2454 codec.

2662-----------------
2663
Fred Drakea8ee94b2008-03-01 02:45:07 +00002664- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002665 644. The mode is now inherited from the py file.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00002671- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002672 issue 215555 for a discussion.
2673
Eric Smitha73fbe72008-02-23 03:09:44 +00002674- Added the future_builtins module, which contains hex() and oct().
2675 These are the PEP 3127 version of these functions, designed to be
2676 compatible with the hex() and oct() builtins from Python 3.0. They
2677 differ slightly in their output formats from the existing, unchanged
2678 Python 2.6 builtins. The expected usage of the future_builtins
2679 module is:
2680 from future_builtins import hex, oct
2681
Eric Smith7ef40bf2008-02-20 23:34:22 +00002682- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2683 exponents for exponents with absolute value < 100. Follows C99
2684 standard. This is a change on Windows, which would use 3 digits.
2685 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2686 so that any alterations it does to the resulting string will be
2687 available in stringlib/formatter.h (for float.__format__).
2688
Eric Smith5a3c1352008-02-19 13:21:56 +00002689- Implemented PEP 3101, Advanced String Formatting. This adds a new
2690 builtin format(); a format() method for str and unicode; a
2691 __format__() method to object, str, unicode, int, long, float, and
2692 datetime; the class string.Formatter; and the C API
2693 PyObject_Format().
2694
Georg Brandl3ee81df2008-05-17 18:14:43 +00002695- Fixed several potential crashes, all caused by specially crafted
2696 __del__ methods exploiting objects in temporarily inconsistent
2697 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002698
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002699- Issue #2115: Important speedup in setting __slot__ attributes. Also

Georg Brandl3ee81df2008-05-17 18:14:43 +00002706- Clear all free lists during a gc.collect() of the highest generation
2707 in order to allow pymalloc to free more arenas. Python may give back
2708 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002709
Georg Brandl3ee81df2008-05-17 18:14:43 +00002710- Issue #2045: Fix an infinite recursion triggered when printing a

Georg Brandl3ee81df2008-05-17 18:14:43 +00002740- Patch #1473257: generator objects gain a gi_code attribute. This is
2741 the same object as the func_code attribute of the function that
2742 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002743
Georg Brandl3ee81df2008-05-17 18:14:43 +00002744- Issue #1920: "while 0" statements were completely removed by the
2745 compiler, even in the presence of an "else" clause, which is
2746 supposed to be run when the condition is false. Now the compiler
2747 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002748
Guido van Rossumeead05f2008-01-24 18:21:02 +00002749- A few crashers fixed: weakref_in_del.py (issue #1377858);
2750 loosing_dict_ref.py (issue #1303614, test67.py);
2751 borrowed_ref_[34].py (not in tracker).

2756
Georg Brandl3ee81df2008-05-17 18:14:43 +00002757- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002758 several extension methods and modules do not work without unicode
2759 support.
2760

2765
Georg Brandl6caad7d2008-01-26 14:19:22 +00002766- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002767 added.
2768
Christian Heimesc94e2b52008-01-14 04:13:37 +00002769- sys.float_info / PyFloat_GetInfo: The floating point information
2770 object was converted from a dict to a specialized structseq object.
2771
Georg Brandl3ee81df2008-05-17 18:14:43 +00002772- Patch #1816: Added sys.flags structseq. It exposes the status of
2773 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002774
Georg Brandl3ee81df2008-05-17 18:14:43 +00002775- Objects/structseq.c: Implemented new structseq representation. The
2776 patch makes structseqs (e.g. the return value of os.stat) more
2777 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002778
Georg Brandl3ee81df2008-05-17 18:14:43 +00002779- Patch #1700288: added a type attribute cache that caches method
2780 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002781
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002782- Bug #1776: __import__() no longer accepts filenames on any platform.
2783 The first parameter to __import__() must be a valid module name.

2788 envvar and sys.dont_write_bytecode attribute. All these can be set
2789 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002790
Georg Brandl3ee81df2008-05-17 18:14:43 +00002791- Improve some exception messages when Windows fails to load an
2792 extension module. Now we get for example '%1 is not a valid Win32
2793 application' instead of 'error code 193'.

2850
Georg Brandl3ee81df2008-05-17 18:14:43 +00002851- The enumerate() builtin function is no longer bounded to sequences
2852 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2853 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002854
Georg Brandl3ee81df2008-05-17 18:14:43 +00002855- Issue #1686386: Tuple's tp_repr did not take into account the
2856 possibility of having a self-referential tuple, which is possible
2857 from C code. Nor did object's tp_str consider that a type's tp_str
2858 could do something that could lead to an inifinite recursion.
2859 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2860 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002861
Georg Brandl3ee81df2008-05-17 18:14:43 +00002862- Issue #1164: It was possible to trigger deadlock when using the
2863 'print' statement to write to a file since the GIL was not released
2864 as needed. Now PyObject_Print() does the right thing along with
2865 various tp_print implementations of the built-in types and those in
2866 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002867

Georg Brandl3ee81df2008-05-17 18:14:43 +00002876 PyObject_Call() never calling back out to Python code to trigger
2877 recursion depth updates/checks. Required the creation of a static
2878 RuntimeError instance in case normalizing an exception put the
2879 recursion check value past its limit. Fixes crashers

2929 now stricter in rejecting excess arguments. The only time when
2930 either allows excess arguments is when it is not overridden and the
2931 other one is. For backwards compatibility, when both are
2932 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002933 warning later). Also, type.__init__() insists on the same signature
2934 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002936- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2937 object to complex using its __complex__() method before falling back
2938 to the __float__() method. Therefore, the functions in the cmath
2939 module now can operate on objects that define a __complex__()
2940 method.

2959 case, even when converting the value to a string failed.
2960
Georg Brandl871f1bc2007-03-12 13:17:36 +00002961- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002962 its argument, if it exists. If not, it will work like before. This
2963 allows customizing the output of dir() in the presence of a
2964 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00002976- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002977 makes the filenames the warning module prints much more sensible
2978 when a PYTHONSTARTUP file is used.

2992 sq_ass_slice instead of the sq_slice slot.
2993
Georg Brandl3ee81df2008-05-17 18:14:43 +00002994- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00003046- Bug #1545497: when given an explicit base, int() did ignore NULs
3047 embedded in the string to convert.
3048
Georg Brandl846f73a2006-10-08 07:11:54 +00003049- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003097 generator expressions (x for x, in ... ) works again. Fixing this
3098 problem required changing the .pyc magic number. This means that
3099 .pyc files generated before 2.5c2 will be regenerated.

3904 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00003905
Georg Brandl3ee81df2008-05-17 18:14:43 +00003906- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3907 with RFC 3207 and forgets any knowledge obtained from the server not
3908 obtained from the TLS negotiation itself. Patch contributed by Bill
3909 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003910
Georg Brandl3ee81df2008-05-17 18:14:43 +00003911- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003912 that the SMTP.starttls() caller no longer needs to call ehlo()
3913 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003914 does not claim to support starttls. Adds the
3915 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3916 Fenner.

3996 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3997 silently miscode subclasses of those types. Now, it raises a
3998 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003999

Georg Brandl3ee81df2008-05-17 18:14:43 +00004014 time so that opening a database previously created with the DB_DUP
4015 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4016 opens. Specifically: dictionary assignment to a DB object will
4017 replace all values for a given key when the database allows
4018 duplicate values. DB users should use DB.put(k, v) when they want
4019 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004020

4026 characters with ASCII value less than 32. Also, it correctly quotes
4027 dots only if they occur on a single line, as opposed to the previous
4028 behavior of quoting dots if they are the second character of any
4029 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004030
