Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +0000174- Issue #2670: Fix a failure in urllib2.build_opener(), when passed two
175 handlers that derive the same default base class.
176
Christian Heimese74c8f22008-04-19 02:23:57 +0000177- Added kill, terminate and send_signal(sig) to subprocess.Popen.

186 passed a value less than or equal to zero.
187
Brett Cannone9746892008-04-12 23:44:07 +0000188- Issue #1631171: Re-implement the 'warnings' module in C (the original Python
189 code has been kept as backup). This will allow for using the 'warning's
190 machinery in such places as the parser where use of pure Python code is not
Brett Cannonb457dda2008-05-02 02:25:09 +0000191 possible. Both the ``showarning()`` and ``formatwarning()`` gain an
192 optional 'line' argument which is not called by default for
Brett Cannon8a232cc2008-05-05 05:32:07 +0000193 backwards-compatibility reasons. Setting ``warnings.showwarning()`` to
194 an implementation that lacks support for the ``line`` argument will raise a
195 DeprecationWarning.

221 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +0000222
Skip Montanarob131f042008-04-18 20:35:46 +0000223- Issue #2014: Allow XML-RPC datetime objects to have dates before

241 threads at once without fear of crashing the Python interpreter. If
242 file.close() is called while an object is in use by another thread
243 an IOError exception will be raised and the file will not be closed.
244
Thomas Hellerf7906482008-04-04 19:43:25 +0000245- The bundled libffi copy is now in sync with the recently released
246 libffi3.0.5 version, apart from some small changes to

251 environment. This supports setup.py scripts that refer to data files.
252
Barry Warsawba437742008-04-04 01:34:41 +0000253Tests
254-----
Trent Nelsone41b0062008-04-08 23:47:30 +0000255- Issue #2550: The approach used by client/server code for obtaining ports
256 to listen on in network-oriented tests has been refined in an effort to
257 facilitate running multiple instances of the entire regression test suite
258 in parallel without issue. test_support.bind_port() has been fixed such
259 that it will always return a unique port -- which wasn't always the case
260 with the previous implementation, especially if socket options had been
261 set that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
262 new implementation of bind_port() will actually raise an exception if it
263 is passed an AF_INET/SOCK_STREAM socket with either the SO_REUSEADDR or
264 SO_REUSEPORT socket option set. Furthermore, if available, bind_port()
265 will set the SO_EXCLUSIVEADDRUSE option on the socket it's been passed.
266 This currently only applies to Windows. This option prevents any other
267 sockets from binding to the host/port we've bound to, thus removing the
268 possibility of the 'non-deterministic' behaviour, as Microsoft puts it,
269 that occurs when a second SOCK_STREAM socket binds and accepts to a
270 host/port that's already been bound by another socket. The optional
271 preferred port parameter to bind_port() has been removed. Under no
272 circumstances should tests be hard coding ports!
273
274 test_support.find_unused_port() has also been introduced, which will pass
275 a temporary socket object to bind_port() in order to obtain an unused port.
276 The temporary socket object is then closed and deleted, and the port is
277 returned. This method should only be used for obtaining an unused port
278 in order to pass to an external program (i.e. the -accept [port] argument
279 to openssl's s_server mode) or as a parameter to a server-oriented class
280 that doesn't give you direct access to the underlying socket used.
281
282 Finally, test_support.HOST has been introduced, which should be used for
283 the host argument of any relevant socket calls (i.e. bind and connect).
284
285 The following tests were updated to following the new conventions:
286 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
287 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
288 test_asynchat and test_socket_ssl.
289
290 It is now possible for multiple instances of the regression test suite to
291 run in parallel without issue.

561 These are the PEP 3127 version of these functions, designed to be
562 compatible with the hex() and oct() builtins from Python 3.0. They
563 differ slightly in their output formats from the existing, unchanged
564 Python 2.6 builtins. The expected usage of the future_builtins
565 module is:
566 from future_builtins import hex, oct
567
Eric Smith7ef40bf2008-02-20 23:34:22 +0000568- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
569 exponents for exponents with absolute value < 100. Follows C99
570 standard. This is a change on Windows, which would use 3 digits.
571 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
572 so that any alterations it does to the resulting string will be
573 available in stringlib/formatter.h (for float.__format__).

605 ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +0000606 to compact the internal free lists of pre-allocted ints and floats.
607
Christian Heimes951cc0f2008-01-31 23:08:23 +0000608- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.

Mark Dickinson105be772008-01-31 22:17:37 +0000611- Issue #1678380: Fix a bug that identifies 0j and -0j when they appear
612 in the same code unit.
613
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +0000614- Issue #2025 : Add tuple.count() and tuple.index() methods to comply with
615 the collections.Sequence API.
616
Christian Heimes4d4f2702008-01-30 11:32:37 +0000617- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and linebreak
618 detection
619
Christian Heimes422051a2008-02-04 18:00:12 +0000620- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear the
Christian Heimes908caac2008-01-27 23:34:59 +0000621 internal lookup cache for ref leak tests.
622
Georg Brandl0cdf9a32008-01-26 14:14:20 +0000623- Patch #1473257: generator objects gain a gi_code attribute. This is the
624 same object as the func_code attribute of the function that produced the
625 generator.
626
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +0000627- Issue #1920: "while 0" statements were completely removed by the compiler,
Vinay Sajipb7edfc42008-04-02 21:10:23 +0000628 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +0000629 the condition is false. Now the compiler correctly emits bytecode for the
630 "else" suite.
631
Guido van Rossumeead05f2008-01-24 18:21:02 +0000632- A few crashers fixed: weakref_in_del.py (issue #1377858);
633 loosing_dict_ref.py (issue #1303614, test67.py);
634 borrowed_ref_[34].py (not in tracker).
635
Vinay Sajipd7cf32e2008-01-24 12:43:33 +0000636- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +0000637 suppressed while an extension is loaded by calling SetErrorMode in
638 dynload_win.c. The error is still reported properly.
639
Christian Heimes082c9b02008-01-23 14:20:50 +0000640- Bug #1915: Python compiles with --enable-unicode=no again. However
641 several extension methods and modules do not work without unicode
642 support.
643
Georg Brandl26543b12008-01-21 18:36:51 +0000644- Issue #1882: when compiling code from a string, encoding cookies in the
645 second line of code were not always recognized correctly.
646
Georg Brandl14404b62008-01-19 19:27:05 +0000647- Issue #1679: "0x" was taken as a valid integer literal.
648
Georg Brandl6caad7d2008-01-26 14:19:22 +0000649- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +0000650 added.
651
Christian Heimesc94e2b52008-01-14 04:13:37 +0000652- sys.float_info / PyFloat_GetInfo: The floating point information
653 object was converted from a dict to a specialized structseq object.
654
Christian Heimesf31b69f2008-01-14 03:42:48 +0000655- Patch #1816: Added sys.flags structseq. It exposes the status of most
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000656 command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +0000657
Georg Brandl6caad7d2008-01-26 14:19:22 +0000658- Objects/structseq.c: Implemented new structseq representation. The patch
Christian Heimesf31b69f2008-01-14 03:42:48 +0000659 makes structseqs (e.g. the return value of os.stat) more readable.
Christian Heimes9c201962008-01-14 03:33:52 +0000660
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +0000661- Patch #1700288: added a type attribute cache that caches method accesses,
662 resulting in speedups in heavily object-oriented code.
663
Neal Norwitz3fc15b82008-01-10 05:42:58 +0000664- Bug #1776: __import__() no longer accepts filenames on any platform.
665 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +0000666
Georg Brandlaed6c662008-01-07 17:25:53 +0000667- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
668
Georg Brandl2da0fce2008-01-07 17:09:35 +0000669- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE envvar
670 and sys.dont_write_bytecode attribute. All these can be set to forbid Python
671 to attempt to write compiled bytecode files.
672
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +0000673- Improve some exception messages when Windows fails to load an extension
674 module. Now we get for example '%1 is not a valid Win32 application' instead
675 of 'error code 193'.
676
Christian Heimes8267d1d2008-01-04 00:37:34 +0000677- Bug #1481296: Fixed long(float('nan'))!=0L.
678
Christian Heimeseebb79c2008-01-03 22:32:26 +0000679- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x, y)
680 functions.
Christian Heimese2ca4242008-01-03 20:23:15 +0000681
Christian Heimes0a8143f2007-12-18 23:22:54 +0000682- Issue #1635: Platform independent creation and representation of NaN
683 and INF. float("nan"), float("inf") and float("-inf") now work on every
684 platform with IEEE 754 semantics.
685
Raymond Hettingerfd7ed402007-12-18 21:24:09 +0000686- Compiler now generates simpler and faster code for dictionary literals.
687 The oparg for BUILD_MAP now indicates an estimated dictionary size.
688 There is a new opcode, STORE_MAP, for adding entries to the dictionary.
689
Christian Heimesdb3d6cb2007-12-16 21:39:43 +0000690- Issue #1638: %zd configure test fails on Linux
691
Christian Heimes90e10e72007-12-14 02:35:23 +0000692- Issue #1620: New property decorator syntax was modifying the decorator
693 in place instead of creating a new decorator object.
694
Skip Montanaro26015492007-12-08 15:33:24 +0000695- Issue #1538: Avoid copying string in split/rsplit if the split
696 char is not found.
697
Andrew M. Kuchling395fe442007-12-05 13:27:20 +0000698- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +0000699 SystemError.
700
Nick Coghlanef01d822007-12-03 12:55:17 +0000701- PEP 366: Allow explicit relative imports when executing modules
702 inside packages with the -m switch via a new module level
703 __package__ attribute.
704
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +0000705- Issue #1402: Fix a crash on exit, when another thread is still running, and
706 if the deallocation of its frames somehow calls the PyGILState_Ensure() /
707 PyGILState_Release() functions.
708
Christian Heimes28104c52007-11-27 23:16:44 +0000709- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
710
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000711- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +0000712 attribute of an empty cell object.
713
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +0000714- Issue #1460: The utf-7 incremental decoder did not accept truncated input.
715 It now correctly saves its state between chunks of data.
716
Nick Coghlan327a39b2007-11-18 11:56:28 +0000717- Patch #1739468: Directories and zipfiles containing a __main__.py file can
718 now be directly executed by passing their name to the interpreter. The
719 directory/zipfile is automatically inserted as the first entry in sys.path.
720
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +0000721- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
722 generator expression when at the same time the executed code is closing a
723 paused generator.
724
Raymond Hettinger1760c8a2007-11-08 02:52:43 +0000725- sets and frozensets now have an isdisjoint() method.
726
Raymond Hettinger3f8caa32007-10-24 01:28:33 +0000727- optimize the performance of builtin.sum().
728
Neal Norwitz44f326e2007-10-05 05:29:17 +0000729- Fix warnings found by the new version of the Coverity checker.
730
Raymond Hettinger8f669372007-10-03 21:18:11 +0000731- The enumerate() builtin function is no longer bounded to sequences smaller
732 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
733 shifts from ints to longs.
734
Brett Cannon0b14f242007-09-30 19:45:10 +0000735- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
736 having a self-referential tuple, which is possible from C code. Nor did
737 object's tp_str consider that a type's tp_str could do something that could
738 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
739 respectively, fixed the issues.
740
Brett Cannon01531592007-09-17 03:28:34 +0000741- Issue #1164: It was possible to trigger deadlock when using the 'print'
742 statement to write to a file since the GIL was not released as needed. Now
743 PyObject_Print() does the right thing along with various tp_print
744 implementations of the built-in types and those in the collections module.
745
Brett Cannon4c20bc42007-09-11 21:02:28 +0000746- Issue #1147: Exceptions were directly allowing string exceptions in their
747 throw() method even though string exceptions no longer allowed.
748
Brett Cannona0c05512007-09-10 21:38:27 +0000749- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
750 list by using the recursion counter.
751
Brett Cannon1e534b52007-09-07 04:18:30 +0000752- Issue #1202533: Fix infinite recursion calls triggered by calls to
753 PyObject_Call() never calling back out to Python code to trigger recursion
754 depth updates/checks. Required the creation of a static RuntimeError
755 instance in case normalizing an exception put the recursion check value past
756 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
757
Martin v. Löwisa5136192007-09-04 14:19:28 +0000758- Patch #1031213: Decode source line in SyntaxErrors back to its original source
759 encoding.
760
Georg Brandl7c3b50d2007-07-12 08:38:00 +0000761- Patch #1673759: add a missing overflow check when formatting floats
762 with %G.
763
Neal Norwitzdb2b1b32007-06-11 07:36:24 +0000764- Prevent expandtabs() on string and unicode objects from causing a segfault
765 when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +0000766
Martin v. Löwisda587ab2007-06-08 17:29:20 +0000767- Bug #1733488: Fix compilation of bufferobject.c on AIX.
768
Georg Brandl25497a12007-06-01 19:20:27 +0000769- Bug #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +0000770
Neal Norwitz0ac60192007-05-27 04:08:54 +0000771- Add new attribute names for function objects. All the func_* become
772 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
773
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +0000774- Add -3 option to the interpreter to warn about features that are
775 deprecated and will be changed/removed in Python 3.0.
776
Georg Brandl2134e752007-05-21 20:34:16 +0000777- Patch #1686487: you can now pass any mapping after '**' in function
778 calls.
779
Collin Winter62903052007-05-18 23:11:24 +0000780- except clauses may now be spelled either "except E, target:" or
781 "except E as target:". This is to provide forwards compatibility with
782 Python 3.0.
783
Brett Cannon229cee22007-05-05 01:34:02 +0000784- Deprecate BaseException.message as per PEP 352.
785
Armin Rigo9790a272007-05-02 19:23:31 +0000786- Bug #1303614: don't expose object's __dict__ when the dict is
787 inherited from a builtin base.
788
Vinay Sajip8549ce32007-05-06 17:53:37 +0000789- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +0000790 setting a plain string, ie don't expand to single letter identifiers.
791
Raymond Hettinger13936692007-04-11 18:40:58 +0000792- Request #1191699: Slices can now be pickled.
793
Raymond Hettinger4db5fe92007-04-12 04:10:00 +0000794- Request #1193128: str.translate() now allows a None argument for
795 translations that only remove characters without re-mapping the
796 remaining characters.
797
Georg Brandl5cb76c12007-03-21 09:00:39 +0000798- Patch #1682205: a TypeError while unpacking an iterable is no longer
799 masked by a generic one with the message "unpack non-sequence".
800
Neal Norwitzaa754b72007-03-21 06:39:48 +0000801- Remove unused file Python/fmod.c.
802
Guido van Rossum143b5642007-03-23 04:58:42 +0000803- Bug #1683368: The object.__init__() and object.__new__() methods are
804 now stricter in rejecting excess arguments. The only time when
805 either allows excess arguments is when it is not overridden and the
806 other one is. For backwards compatibility, when both are
807 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +0000808 warning later). Also, type.__init__() insists on the same signature
809 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +0000810
Georg Brandl2b869942007-03-17 16:08:45 +0000811- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
812 to complex using its __complex__() method before falling back to the
813 __float__() method. Therefore, the functions in the cmath module now
814 can operate on objects that define a __complex__() method.
815
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +0000816- Patch #1623563: allow __class__ assignment for classes with __slots__.
817 The old and the new class are still required to have the same slot names.
818
Collin Winter77c67bd2007-03-16 04:11:30 +0000819- Patch #1642547: Fix an error/crash when encountering syntax errors in
820 complex if statements.
821
Žiga Seilnacht20f43d32007-03-15 11:44:55 +0000822- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
823 is called with an object that is faking its type.
824
Žiga Seilnacht71436f02007-03-14 12:24:09 +0000825- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
826 name.
827
Georg Brandl5240d742007-03-13 20:46:32 +0000828- Patch #1444529: the builtin compile() now accepts keyword arguments.
829
Georg Brandl7b9c5552007-03-12 14:30:05 +0000830- Bug #1678647: write a newline after printing an exception in any
831 case, even when converting the value to a string failed.
832
Georg Brandl871f1bc2007-03-12 13:17:36 +0000833- The dir() function has been extended to call the __dir__() method on
834 its argument, if it exists. If not, it will work like before. This allows
835 customizing the output of dir() in the presence of a __getattr__().
836
Collin Winter276887b2007-03-12 16:11:39 +0000837- Patch #922167: Python no longer segfaults when faced with infinitely
838 self-recursive reload() calls (as reported by bug #742342).
839
Žiga Seilnacht89032082007-03-11 15:54:54 +0000840- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
841
Collin Wintere38051d2007-03-09 20:33:07 +0000842- Patch #1491866: change the complex() constructor to allow parthensized
843 forms. This means complex(repr(x)) now works instead of raising a
844 ValueError.
845
Georg Brandlaa2321b2007-03-07 00:40:28 +0000846- Patch #703779: unset __file__ in __main__ after running a file. This
847 makes the filenames the warning module prints much more sensible when
848 a PYTHONSTARTUP file is used.
849
Georg Brandl49aafc92007-03-07 00:34:46 +0000850- Variant of patch #697613: don't exit the interpreter on a SystemExit
851 exception if the -i command line option or PYTHONINSPECT environment
852 variable is given, but break into the interactive interpreter just like
853 on other exceptions or normal program exit.
854
Georg Brandl00cd8182007-03-06 18:41:12 +0000855- Patch #1638879: don't accept strings with embedded NUL bytes in long().
856
Georg Brandl098cd692007-03-06 12:17:50 +0000857- Bug #1674503: close the file opened by execfile() in an error condition.
858
Georg Brandl0fca97a2007-03-05 22:28:08 +0000859- Patch #1674228: when assigning a slice (old-style), check for the
860 sq_ass_slice instead of the sq_slice slot.
861
Neal Norwitz88516a62007-02-26 22:41:45 +0000862- When printing an unraisable error, don't print exceptions. before the name.
863 This duplicates the behavior whening normally printing exceptions.
864
Martin v. Löwisfd963262007-02-09 12:19:32 +0000865- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
866
Brett Cannon129bd522007-01-30 21:34:36 +0000867- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
868 catch a string exception raises DeprecationWarning.
869
Brett Cannonf5bee302007-01-23 23:21:22 +0000870- Bug #1377858: Fix the segfaulting of the interpreter when an object created
871 a weakref on itself during a __del__ call for new-style classes (classic
872 classes still have the bug).
873
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000874- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
875 frame's thread state.
876
Thomas Wouters6ed19652007-01-23 13:50:49 +0000877- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
878
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000879- Prevent seg fault on shutdown which could occur if an object
880 raised a warning.
881
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000882- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
883 to avoid relying on atexit.
884
Raymond Hettinger94547f72006-12-20 06:42:06 +0000885- Bug #1590891: random.randrange don't return correct value for big number
886
Georg Brandl283a1352006-11-19 08:48:30 +0000887- Patch #1586791: Better exception messages for some operations on strings,
888 tuples and lists.
889
Martin v. Löwis056dac12006-11-12 18:24:26 +0000890- Bug #1067760: Deprecate passing floats to file.seek.
891

1460 and TestSuite subclasses (not instances) are no longer accepted in

1462 never made sense with ordinary subclasses -- the failure just occurred
1463 later, with a more cumbersome exception.

1734
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00001735- Issue829951: In the smtplib module, SMTP.starttls() now complies with
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00001736 RFC 3207 and forgets any knowledge obtained from the server not obtained
1737 from the TLS negotiation itself. Patch contributed by Bill Fenner.
1738
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00001739- Issue1339: The smtplib.SMTP class has been refactored a bit such
1740 that the SMTP.starttls() caller no longer needs to call ehlo()
1741 beforehand. SMTP.starttls() now raises an exception of the server
1742 does not claim to support starttls. Adds the SMTP.ehlo_or_helo_if_needed()
1743 method. Patch contributed by Bill Fenner.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00001833- pybsddb.sf.net Bug #477182: Load the database flags at database open
1834 time so that opening a database previously created with the DB_DUP or
1835 DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
1836 Specifically: dictionary assignment to a DB object will replace all
1837 values for a given key when the database allows duplicate values.
1838 DB users should use DB.put(k, v) when they want to store duplicates; not
1839 DB[k] = v.
1840
Gregory P. Smithac11e022007-11-05 02:56:31 +00001841- Add the bsddb.db.DBEnv.lock_id_free method.

2164
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00002165- ``PySet_Add()`` can now modify a newly created frozenset. Similarly to
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002166 ``PyTuple_SetItem``, it can be used to populate a brand new frozenset; but
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00002167 it does not steal a reference to the added item.
2168
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002169- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

2176
2177- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
2178 ``PyFloat_GetInfo()`` to the float API.
2179
2180- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
2181 format code incorrectly truncated the length to an int, even when
2182 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
2183 results with huge strings.
2184
2185- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE
2186 and Py_REFCNT.
2187
2188- PEP 3123: Provide forward compatibility with Python 3.0, while keeping
2189 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
2190 PyVarObject_HEAD_INIT.
2191
2192- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
2193
2194- Patch #1733960: Allow T_LONGLONG to accept ints.
2195
2196- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
2197

2201
2202- Fix some leftovers from the conversion from int to Py_ssize_t
2203 (relevant to strings and sequences of more than 2**31 items).
2204
2205- Make _PyGILState_NoteThreadState() static, it was not used anywhere
2206 outside of pystate.c and should not be necessary.
2207
Christian Heimes000a0742008-01-03 22:16:32 +00002208- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do absolute
2209 imports. In earlier versions they might have used relative imports under
2210 some conditions.
2211
Andrew M. Kuchlingadc60ab2008-01-04 02:26:00 +00002212- Added case insensitive comparison methods ``PyOS_stricmp(char*, char*)``
Christian Heimes000a0742008-01-03 22:16:32 +00002213 and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
