Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +0000163- Issue #2670: Fix a failure in urllib2.build_opener(), when passed two

175 passed a value less than or equal to zero.
176
Brett Cannone9746892008-04-12 23:44:07 +0000177- Issue #1631171: Re-implement the 'warnings' module in C (the original Python
178 code has been kept as backup). This will allow for using the 'warning's
179 machinery in such places as the parser where use of pure Python code is not
Brett Cannonb457dda2008-05-02 02:25:09 +0000180 possible. Both the ``showarning()`` and ``formatwarning()`` gain an
181 optional 'line' argument which is not called by default for
Brett Cannon8a232cc2008-05-05 05:32:07 +0000182 backwards-compatibility reasons. Setting ``warnings.showwarning()`` to
183 an implementation that lacks support for the ``line`` argument will raise a
184 DeprecationWarning.

230 threads at once without fear of crashing the Python interpreter. If
231 file.close() is called while an object is in use by another thread
232 an IOError exception will be raised and the file will not be closed.
233
Thomas Hellerf7906482008-04-04 19:43:25 +0000234- The bundled libffi copy is now in sync with the recently released

243-----
Trent Nelsone41b0062008-04-08 23:47:30 +0000244- Issue #2550: The approach used by client/server code for obtaining ports
245 to listen on in network-oriented tests has been refined in an effort to
246 facilitate running multiple instances of the entire regression test suite
247 in parallel without issue. test_support.bind_port() has been fixed such
248 that it will always return a unique port -- which wasn't always the case
249 with the previous implementation, especially if socket options had been
250 set that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
251 new implementation of bind_port() will actually raise an exception if it
252 is passed an AF_INET/SOCK_STREAM socket with either the SO_REUSEADDR or
253 SO_REUSEPORT socket option set. Furthermore, if available, bind_port()
254 will set the SO_EXCLUSIVEADDRUSE option on the socket it's been passed.
255 This currently only applies to Windows. This option prevents any other
256 sockets from binding to the host/port we've bound to, thus removing the
257 possibility of the 'non-deterministic' behaviour, as Microsoft puts it,
258 that occurs when a second SOCK_STREAM socket binds and accepts to a
259 host/port that's already been bound by another socket. The optional
260 preferred port parameter to bind_port() has been removed. Under no
261 circumstances should tests be hard coding ports!
262
263 test_support.find_unused_port() has also been introduced, which will pass
264 a temporary socket object to bind_port() in order to obtain an unused port.
265 The temporary socket object is then closed and deleted, and the port is
266 returned. This method should only be used for obtaining an unused port
267 in order to pass to an external program (i.e. the -accept [port] argument
268 to openssl's s_server mode) or as a parameter to a server-oriented class
269 that doesn't give you direct access to the underlying socket used.
270
271 Finally, test_support.HOST has been introduced, which should be used for
272 the host argument of any relevant socket calls (i.e. bind and connect).
273
274 The following tests were updated to following the new conventions:
275 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
276 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
277 test_asynchat and test_socket_ssl.
278
279 It is now possible for multiple instances of the regression test suite to
280 run in parallel without issue.

536Core and builtins
537-----------------
538
Fred Drakea8ee94b2008-03-01 02:45:07 +0000539- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +0000540 644. The mode is now inherited from the py file.

548
Eric Smitha73fbe72008-02-23 03:09:44 +0000549- Added the future_builtins module, which contains hex() and oct().
550 These are the PEP 3127 version of these functions, designed to be
551 compatible with the hex() and oct() builtins from Python 3.0. They
552 differ slightly in their output formats from the existing, unchanged
553 Python 2.6 builtins. The expected usage of the future_builtins
554 module is:
555 from future_builtins import hex, oct
556
Eric Smith7ef40bf2008-02-20 23:34:22 +0000557- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
558 exponents for exponents with absolute value < 100. Follows C99
559 standard. This is a change on Windows, which would use 3 digits.
560 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
561 so that any alterations it does to the resulting string will be
562 available in stringlib/formatter.h (for float.__format__).
563
Eric Smith5a3c1352008-02-19 13:21:56 +0000564- Implemented PEP 3101, Advanced String Formatting. This adds a new
565 builtin format(); a format() method for str and unicode; a
566 __format__() method to object, str, unicode, int, long, float, and
567 datetime; the class string.Formatter; and the C API
568 PyObject_Format().
569
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +0000570- Fixed several potential crashes, all caused by specially crafted __del__
571 methods exploiting objects in temporarily inconsistent state.
572
Vinay Sajipb7edfc42008-04-02 21:10:23 +0000573- Issue #2115: Important speedup in setting __slot__ attributes. Also

586
Christian Heimesf75dbef2008-02-08 00:11:31 +0000587- Fixed a minor memory leak in dictobject.c. The content of the free
588 list was not freed on interpreter shutdown.
589
Christian Heimes6075a822008-02-06 12:44:34 +0000590- Limit free list of method and builtin function objects to 256 entries
591 each.
592
Amaury Forgeot d'Arc578a8ca2008-02-04 20:53:14 +0000593- Patch #1953: Added ``sys._compact_freelists()`` and the C API functions
594 ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +0000595 to compact the internal free lists of pre-allocted ints and floats.

Georg Brandl0cdf9a32008-01-26 14:14:20 +0000612- Patch #1473257: generator objects gain a gi_code attribute. This is the
613 same object as the func_code attribute of the function that produced the
614 generator.
615
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +0000616- Issue #1920: "while 0" statements were completely removed by the compiler,
Vinay Sajipb7edfc42008-04-02 21:10:23 +0000617 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +0000618 the condition is false. Now the compiler correctly emits bytecode for the
619 "else" suite.
620
Guido van Rossumeead05f2008-01-24 18:21:02 +0000621- A few crashers fixed: weakref_in_del.py (issue #1377858);
622 loosing_dict_ref.py (issue #1303614, test67.py);
623 borrowed_ref_[34].py (not in tracker).
624
Vinay Sajipd7cf32e2008-01-24 12:43:33 +0000625- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +0000626 suppressed while an extension is loaded by calling SetErrorMode in
627 dynload_win.c. The error is still reported properly.
628
Christian Heimes082c9b02008-01-23 14:20:50 +0000629- Bug #1915: Python compiles with --enable-unicode=no again. However
630 several extension methods and modules do not work without unicode
631 support.
632
Georg Brandl26543b12008-01-21 18:36:51 +0000633- Issue #1882: when compiling code from a string, encoding cookies in the
634 second line of code were not always recognized correctly.
635
Georg Brandl14404b62008-01-19 19:27:05 +0000636- Issue #1679: "0x" was taken as a valid integer literal.
637
Georg Brandl6caad7d2008-01-26 14:19:22 +0000638- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +0000639 added.
640
Christian Heimesc94e2b52008-01-14 04:13:37 +0000641- sys.float_info / PyFloat_GetInfo: The floating point information
642 object was converted from a dict to a specialized structseq object.
643
Christian Heimesf31b69f2008-01-14 03:42:48 +0000644- Patch #1816: Added sys.flags structseq. It exposes the status of most
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000645 command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +0000646
Georg Brandl6caad7d2008-01-26 14:19:22 +0000647- Objects/structseq.c: Implemented new structseq representation. The patch
Christian Heimesf31b69f2008-01-14 03:42:48 +0000648 makes structseqs (e.g. the return value of os.stat) more readable.
Christian Heimes9c201962008-01-14 03:33:52 +0000649
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +0000650- Patch #1700288: added a type attribute cache that caches method accesses,
651 resulting in speedups in heavily object-oriented code.
652
Neal Norwitz3fc15b82008-01-10 05:42:58 +0000653- Bug #1776: __import__() no longer accepts filenames on any platform.
654 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +0000655
Georg Brandlaed6c662008-01-07 17:25:53 +0000656- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
657
Georg Brandl2da0fce2008-01-07 17:09:35 +0000658- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE envvar
659 and sys.dont_write_bytecode attribute. All these can be set to forbid Python
660 to attempt to write compiled bytecode files.
661
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +0000662- Improve some exception messages when Windows fails to load an extension
663 module. Now we get for example '%1 is not a valid Win32 application' instead
664 of 'error code 193'.
665
Christian Heimes8267d1d2008-01-04 00:37:34 +0000666- Bug #1481296: Fixed long(float('nan'))!=0L.
667
Christian Heimeseebb79c2008-01-03 22:32:26 +0000668- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x, y)
669 functions.
Christian Heimese2ca4242008-01-03 20:23:15 +0000670
Christian Heimes0a8143f2007-12-18 23:22:54 +0000671- Issue #1635: Platform independent creation and representation of NaN
672 and INF. float("nan"), float("inf") and float("-inf") now work on every
673 platform with IEEE 754 semantics.
674
Raymond Hettingerfd7ed402007-12-18 21:24:09 +0000675- Compiler now generates simpler and faster code for dictionary literals.
676 The oparg for BUILD_MAP now indicates an estimated dictionary size.
677 There is a new opcode, STORE_MAP, for adding entries to the dictionary.
678
Christian Heimesdb3d6cb2007-12-16 21:39:43 +0000679- Issue #1638: %zd configure test fails on Linux
680
Christian Heimes90e10e72007-12-14 02:35:23 +0000681- Issue #1620: New property decorator syntax was modifying the decorator
682 in place instead of creating a new decorator object.
683
Skip Montanaro26015492007-12-08 15:33:24 +0000684- Issue #1538: Avoid copying string in split/rsplit if the split
685 char is not found.
686
Andrew M. Kuchling395fe442007-12-05 13:27:20 +0000687- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +0000688 SystemError.
689
Nick Coghlanef01d822007-12-03 12:55:17 +0000690- PEP 366: Allow explicit relative imports when executing modules
691 inside packages with the -m switch via a new module level
692 __package__ attribute.
693
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +0000694- Issue #1402: Fix a crash on exit, when another thread is still running, and
695 if the deallocation of its frames somehow calls the PyGILState_Ensure() /
696 PyGILState_Release() functions.
697
Christian Heimes28104c52007-11-27 23:16:44 +0000698- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
699
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000700- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +0000701 attribute of an empty cell object.
702
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +0000703- Issue #1460: The utf-7 incremental decoder did not accept truncated input.
704 It now correctly saves its state between chunks of data.
705
Nick Coghlan327a39b2007-11-18 11:56:28 +0000706- Patch #1739468: Directories and zipfiles containing a __main__.py file can
707 now be directly executed by passing their name to the interpreter. The
708 directory/zipfile is automatically inserted as the first entry in sys.path.
709
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +0000710- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
711 generator expression when at the same time the executed code is closing a
712 paused generator.
713
Raymond Hettinger1760c8a2007-11-08 02:52:43 +0000714- sets and frozensets now have an isdisjoint() method.
715
Raymond Hettinger3f8caa32007-10-24 01:28:33 +0000716- optimize the performance of builtin.sum().
717
Neal Norwitz44f326e2007-10-05 05:29:17 +0000718- Fix warnings found by the new version of the Coverity checker.
719
Raymond Hettinger8f669372007-10-03 21:18:11 +0000720- The enumerate() builtin function is no longer bounded to sequences smaller
721 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
722 shifts from ints to longs.
723
Brett Cannon0b14f242007-09-30 19:45:10 +0000724- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
725 having a self-referential tuple, which is possible from C code. Nor did
726 object's tp_str consider that a type's tp_str could do something that could
727 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
728 respectively, fixed the issues.
729
Brett Cannon01531592007-09-17 03:28:34 +0000730- Issue #1164: It was possible to trigger deadlock when using the 'print'
731 statement to write to a file since the GIL was not released as needed. Now
732 PyObject_Print() does the right thing along with various tp_print
733 implementations of the built-in types and those in the collections module.
734
Brett Cannon4c20bc42007-09-11 21:02:28 +0000735- Issue #1147: Exceptions were directly allowing string exceptions in their
736 throw() method even though string exceptions no longer allowed.
737
Brett Cannona0c05512007-09-10 21:38:27 +0000738- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
739 list by using the recursion counter.
740
Brett Cannon1e534b52007-09-07 04:18:30 +0000741- Issue #1202533: Fix infinite recursion calls triggered by calls to
742 PyObject_Call() never calling back out to Python code to trigger recursion
743 depth updates/checks. Required the creation of a static RuntimeError
744 instance in case normalizing an exception put the recursion check value past
745 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
746
Martin v. Löwisa5136192007-09-04 14:19:28 +0000747- Patch #1031213: Decode source line in SyntaxErrors back to its original source
748 encoding.
749
Georg Brandl7c3b50d2007-07-12 08:38:00 +0000750- Patch #1673759: add a missing overflow check when formatting floats
751 with %G.
752
Neal Norwitzdb2b1b32007-06-11 07:36:24 +0000753- Prevent expandtabs() on string and unicode objects from causing a segfault
754 when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +0000755
Martin v. Löwisda587ab2007-06-08 17:29:20 +0000756- Bug #1733488: Fix compilation of bufferobject.c on AIX.
757
Georg Brandl25497a12007-06-01 19:20:27 +0000758- Bug #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +0000759
Neal Norwitz0ac60192007-05-27 04:08:54 +0000760- Add new attribute names for function objects. All the func_* become
761 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
762
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +0000763- Add -3 option to the interpreter to warn about features that are
764 deprecated and will be changed/removed in Python 3.0.
765
Georg Brandl2134e752007-05-21 20:34:16 +0000766- Patch #1686487: you can now pass any mapping after '**' in function
767 calls.
768
Collin Winter62903052007-05-18 23:11:24 +0000769- except clauses may now be spelled either "except E, target:" or
770 "except E as target:". This is to provide forwards compatibility with
771 Python 3.0.
772
Brett Cannon229cee22007-05-05 01:34:02 +0000773- Deprecate BaseException.message as per PEP 352.
774
Armin Rigo9790a272007-05-02 19:23:31 +0000775- Bug #1303614: don't expose object's __dict__ when the dict is
776 inherited from a builtin base.
777
Vinay Sajip8549ce32007-05-06 17:53:37 +0000778- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +0000779 setting a plain string, ie don't expand to single letter identifiers.
780
Raymond Hettinger13936692007-04-11 18:40:58 +0000781- Request #1191699: Slices can now be pickled.
782
Raymond Hettinger4db5fe92007-04-12 04:10:00 +0000783- Request #1193128: str.translate() now allows a None argument for
784 translations that only remove characters without re-mapping the
785 remaining characters.
786
Georg Brandl5cb76c12007-03-21 09:00:39 +0000787- Patch #1682205: a TypeError while unpacking an iterable is no longer
788 masked by a generic one with the message "unpack non-sequence".
789
Neal Norwitzaa754b72007-03-21 06:39:48 +0000790- Remove unused file Python/fmod.c.
791
Guido van Rossum143b5642007-03-23 04:58:42 +0000792- Bug #1683368: The object.__init__() and object.__new__() methods are
793 now stricter in rejecting excess arguments. The only time when
794 either allows excess arguments is when it is not overridden and the
795 other one is. For backwards compatibility, when both are
796 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +0000797 warning later). Also, type.__init__() insists on the same signature
798 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +0000799
Georg Brandl2b869942007-03-17 16:08:45 +0000800- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
801 to complex using its __complex__() method before falling back to the
802 __float__() method. Therefore, the functions in the cmath module now
803 can operate on objects that define a __complex__() method.
804
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +0000805- Patch #1623563: allow __class__ assignment for classes with __slots__.
806 The old and the new class are still required to have the same slot names.
807
Collin Winter77c67bd2007-03-16 04:11:30 +0000808- Patch #1642547: Fix an error/crash when encountering syntax errors in
809 complex if statements.
810
Žiga Seilnacht20f43d32007-03-15 11:44:55 +0000811- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
812 is called with an object that is faking its type.
813
Žiga Seilnacht71436f02007-03-14 12:24:09 +0000814- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
815 name.
816
Georg Brandl5240d742007-03-13 20:46:32 +0000817- Patch #1444529: the builtin compile() now accepts keyword arguments.
818
Georg Brandl7b9c5552007-03-12 14:30:05 +0000819- Bug #1678647: write a newline after printing an exception in any
820 case, even when converting the value to a string failed.
821
Georg Brandl871f1bc2007-03-12 13:17:36 +0000822- The dir() function has been extended to call the __dir__() method on
823 its argument, if it exists. If not, it will work like before. This allows
824 customizing the output of dir() in the presence of a __getattr__().
825
Collin Winter276887b2007-03-12 16:11:39 +0000826- Patch #922167: Python no longer segfaults when faced with infinitely
827 self-recursive reload() calls (as reported by bug #742342).
828
Žiga Seilnacht89032082007-03-11 15:54:54 +0000829- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
830
Collin Wintere38051d2007-03-09 20:33:07 +0000831- Patch #1491866: change the complex() constructor to allow parthensized
832 forms. This means complex(repr(x)) now works instead of raising a
833 ValueError.
834
Georg Brandlaa2321b2007-03-07 00:40:28 +0000835- Patch #703779: unset __file__ in __main__ after running a file. This
836 makes the filenames the warning module prints much more sensible when
837 a PYTHONSTARTUP file is used.
838
Georg Brandl49aafc92007-03-07 00:34:46 +0000839- Variant of patch #697613: don't exit the interpreter on a SystemExit
840 exception if the -i command line option or PYTHONINSPECT environment
841 variable is given, but break into the interactive interpreter just like
842 on other exceptions or normal program exit.
843
Georg Brandl00cd8182007-03-06 18:41:12 +0000844- Patch #1638879: don't accept strings with embedded NUL bytes in long().
845
Georg Brandl098cd692007-03-06 12:17:50 +0000846- Bug #1674503: close the file opened by execfile() in an error condition.
847
Georg Brandl0fca97a2007-03-05 22:28:08 +0000848- Patch #1674228: when assigning a slice (old-style), check for the
849 sq_ass_slice instead of the sq_slice slot.
850
Neal Norwitz88516a62007-02-26 22:41:45 +0000851- When printing an unraisable error, don't print exceptions. before the name.
852 This duplicates the behavior whening normally printing exceptions.
853
Martin v. Löwisfd963262007-02-09 12:19:32 +0000854- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
855
Brett Cannon129bd522007-01-30 21:34:36 +0000856- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
857 catch a string exception raises DeprecationWarning.
858
Brett Cannonf5bee302007-01-23 23:21:22 +0000859- Bug #1377858: Fix the segfaulting of the interpreter when an object created
860 a weakref on itself during a __del__ call for new-style classes (classic
861 classes still have the bug).
862
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000863- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
864 frame's thread state.
865
Thomas Wouters6ed19652007-01-23 13:50:49 +0000866- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
867
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000868- Prevent seg fault on shutdown which could occur if an object
869 raised a warning.
870
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000871- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
872 to avoid relying on atexit.
873
Raymond Hettinger94547f72006-12-20 06:42:06 +0000874- Bug #1590891: random.randrange don't return correct value for big number
875
Georg Brandl283a1352006-11-19 08:48:30 +0000876- Patch #1586791: Better exception messages for some operations on strings,
877 tuples and lists.
878
Martin v. Löwis056dac12006-11-12 18:24:26 +0000879- Bug #1067760: Deprecate passing floats to file.seek.
880
Martin v. Löwisa346c092006-11-08 06:48:36 +0000881- Bug #1591996: Correctly forward exception in instance_contains().
882
Neal Norwitz85dbec62006-11-04 19:25:22 +0000883- Bug #1588287: fix invalid assertion for `1,2` in debug builds.
884
Georg Brandlb9f4ad32006-10-29 18:31:42 +0000885- Bug #1576657: when setting a KeyError for a tuple key, make sure that
886 the tuple isn't used as the "exception arguments tuple".
887
Neal Norwitz21997af2006-10-28 21:19:07 +0000888- Bug #1565514, SystemError not raised on too many nested blocks.
889
Thomas Hellerdf08f0b2006-10-27 18:31:36 +0000890- Bug #1576174: WindowsError now displays the windows error code

Georg Brandl2c1375c2006-10-12 11:27:59 +0000899- Bug #1545497: when given an explicit base, int() did ignore NULs

1384 convenience functions for instantiating a Timer and calling its methods.
1385

Collin Winterfaaa2042007-03-10 03:35:34 +00001426 be equal to calling getsockname() on the server's socket. Fixed by
1427 patch #1545011.
Collin Winter22c42ba2007-03-10 02:51:26 +00001428
Andrew M. Kuchlinge45a77a2008-01-19 16:26:13 +00001429- Patch #742598: Add .timeout attribute to SocketServer that calls

1436 returned string up to the first NUL character.
1437
Martin v. Löwis1190a382007-03-09 15:35:55 +00001438- Patch #957003: Implement smtplib.LMTP.

1449 and TestSuite subclasses (not instances) are no longer accepted in

1452 later, with a more cumbersome exception.

Gregory P. Smith2b3ba582008-01-17 08:03:17 +00001725 RFC 3207 and forgets any knowledge obtained from the server not obtained
1726 from the TLS negotiation itself. Patch contributed by Bill Fenner.
1727
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00001728- Issue1339: The smtplib.SMTP class has been refactored a bit such
1729 that the SMTP.starttls() caller no longer needs to call ehlo()
1730 beforehand. SMTP.starttls() now raises an exception of the server
1731 does not claim to support starttls. Adds the SMTP.ehlo_or_helo_if_needed()
1732 method. Patch contributed by Bill Fenner.

1823 time so that opening a database previously created with the DB_DUP or
1824 DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
1825 Specifically: dictionary assignment to a DB object will replace all
1826 values for a given key when the database allows duplicate values.
1827 DB users should use DB.put(k, v) when they want to store duplicates; not
1828 DB[k] = v.
1829

2148-----
2149
Christian Heimes5b970ad2008-02-06 13:33:44 +00002150- Unified naming convention for free lists and their limits. All free lists
2151 in Object/ are named ``free_list``, the counter ``numfree`` and the upper

2153
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00002154- ``PySet_Add()`` can now modify a newly created frozenset. Similarly to
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002155 ``PyTuple_SetItem``, it can be used to populate a brand new frozenset; but
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00002156 it does not steal a reference to the added item.
2157
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002158- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

2161 _FormatV from Python 3.0. Made PyLong_AsSsize_t and PyLong_FromSsize_t
2162 public functions.
2163
2164- Patch #1720595: add T_BOOL to the range of structmember types.
2165
2166- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
2167 ``PyFloat_GetInfo()`` to the float API.
2168
2169- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
2170 format code incorrectly truncated the length to an int, even when
2171 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
2172 results with huge strings.
2173
2174- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE
2175 and Py_REFCNT.
2176
2177- PEP 3123: Provide forward compatibility with Python 3.0, while keeping
2178 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
2179 PyVarObject_HEAD_INIT.
2180
2181- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
2182
2183- Patch #1733960: Allow T_LONGLONG to accept ints.
2184
2185- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
2186
Christian Heimes000a0742008-01-03 22:16:32 +00002187- Added a new API function ``PyImport_ImportModuleNoBlock``.

2190
2191- Fix some leftovers from the conversion from int to Py_ssize_t
2192 (relevant to strings and sequences of more than 2**31 items).
2193
2194- Make _PyGILState_NoteThreadState() static, it was not used anywhere
2195 outside of pystate.c and should not be necessary.
2196
Christian Heimes000a0742008-01-03 22:16:32 +00002197- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do absolute
2198 imports. In earlier versions they might have used relative imports under
2199 some conditions.
2200
Andrew M. Kuchlingadc60ab2008-01-04 02:26:00 +00002201- Added case insensitive comparison methods ``PyOS_stricmp(char*, char*)``
Christian Heimes000a0742008-01-03 22:16:32 +00002202 and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
2203
Neal Norwitz8a267062006-08-19 04:25:29 +00002204- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx macro
2205 so it can be used as an expression.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00002211- Patch #1706: Drop support for Win9x, WinME and NT4. Python now requires
Christian Heimes95d64472008-02-09 19:55:22 +00002212 Windows 2000 or greater. The _WINVER and NTDDI_VERSION macros are set to
2213 Win2k for x86/32bit builds and WinXP for AMD64 builds.
2214
Martin v. Löwis2607e6c2006-11-21 18:20:25 +00002215- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE

Brett Cannon5e263512007-05-20 23:17:38 +00002228- Removed the macfs module. It had been deprecated since Python 2.5. This
2229 lead to the deprecation of macostools.touched() as it relied solely on macfs
2230 and was a no-op under OS X.
