Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +0000159- Issue #2670: Fix a failure in urllib2.build_opener(), when passed two

171 passed a value less than or equal to zero.
172
Brett Cannone9746892008-04-12 23:44:07 +0000173- Issue #1631171: Re-implement the 'warnings' module in C (the original Python
174 code has been kept as backup). This will allow for using the 'warning's
175 machinery in such places as the parser where use of pure Python code is not
Brett Cannonb457dda2008-05-02 02:25:09 +0000176 possible. Both the ``showarning()`` and ``formatwarning()`` gain an
177 optional 'line' argument which is not called by default for
Brett Cannon8a232cc2008-05-05 05:32:07 +0000178 backwards-compatibility reasons. Setting ``warnings.showwarning()`` to
179 an implementation that lacks support for the ``line`` argument will raise a
180 DeprecationWarning.

206 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +0000207
Skip Montanarob131f042008-04-18 20:35:46 +0000208- Issue #2014: Allow XML-RPC datetime objects to have dates before

226 threads at once without fear of crashing the Python interpreter. If
227 file.close() is called while an object is in use by another thread
228 an IOError exception will be raised and the file will not be closed.
229
Thomas Hellerf7906482008-04-04 19:43:25 +0000230- The bundled libffi copy is now in sync with the recently released
231 libffi3.0.5 version, apart from some small changes to
232 Modules/_ctypes/libffi/configure.ac.
233
Fred Drake46c58c12008-04-04 05:41:30 +0000234- Issue #2385: distutils.core.run_script() makes __file__ available, so the
235 controlled environment will more closely mirror the typical script
236 environment. This supports setup.py scripts that refer to data files.
237

239-----
Trent Nelsone41b0062008-04-08 23:47:30 +0000240- Issue #2550: The approach used by client/server code for obtaining ports
241 to listen on in network-oriented tests has been refined in an effort to
242 facilitate running multiple instances of the entire regression test suite
243 in parallel without issue. test_support.bind_port() has been fixed such
244 that it will always return a unique port -- which wasn't always the case
245 with the previous implementation, especially if socket options had been
246 set that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
247 new implementation of bind_port() will actually raise an exception if it
248 is passed an AF_INET/SOCK_STREAM socket with either the SO_REUSEADDR or
249 SO_REUSEPORT socket option set. Furthermore, if available, bind_port()
250 will set the SO_EXCLUSIVEADDRUSE option on the socket it's been passed.
251 This currently only applies to Windows. This option prevents any other
252 sockets from binding to the host/port we've bound to, thus removing the
253 possibility of the 'non-deterministic' behaviour, as Microsoft puts it,
254 that occurs when a second SOCK_STREAM socket binds and accepts to a
255 host/port that's already been bound by another socket. The optional
256 preferred port parameter to bind_port() has been removed. Under no
257 circumstances should tests be hard coding ports!
258
259 test_support.find_unused_port() has also been introduced, which will pass
260 a temporary socket object to bind_port() in order to obtain an unused port.
261 The temporary socket object is then closed and deleted, and the port is
262 returned. This method should only be used for obtaining an unused port
263 in order to pass to an external program (i.e. the -accept [port] argument
264 to openssl's s_server mode) or as a parameter to a server-oriented class
265 that doesn't give you direct access to the underlying socket used.
266
267 Finally, test_support.HOST has been introduced, which should be used for
268 the host argument of any relevant socket calls (i.e. bind and connect).
269
270 The following tests were updated to following the new conventions:
271 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
272 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
273 test_asynchat and test_socket_ssl.
274
275 It is now possible for multiple instances of the regression test suite to
276 run in parallel without issue.

532Core and builtins
533-----------------
534
Fred Drakea8ee94b2008-03-01 02:45:07 +0000535- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +0000536 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +0000537

544
Eric Smitha73fbe72008-02-23 03:09:44 +0000545- Added the future_builtins module, which contains hex() and oct().
546 These are the PEP 3127 version of these functions, designed to be
547 compatible with the hex() and oct() builtins from Python 3.0. They
548 differ slightly in their output formats from the existing, unchanged
549 Python 2.6 builtins. The expected usage of the future_builtins
550 module is:
551 from future_builtins import hex, oct
552
Eric Smith7ef40bf2008-02-20 23:34:22 +0000553- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
554 exponents for exponents with absolute value < 100. Follows C99
555 standard. This is a change on Windows, which would use 3 digits.
556 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
557 so that any alterations it does to the resulting string will be
558 available in stringlib/formatter.h (for float.__format__).
559
Eric Smith5a3c1352008-02-19 13:21:56 +0000560- Implemented PEP 3101, Advanced String Formatting. This adds a new
561 builtin format(); a format() method for str and unicode; a
562 __format__() method to object, str, unicode, int, long, float, and
563 datetime; the class string.Formatter; and the C API
564 PyObject_Format().
565
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +0000566- Fixed several potential crashes, all caused by specially crafted __del__
567 methods exploiting objects in temporarily inconsistent state.
568
Vinay Sajipb7edfc42008-04-02 21:10:23 +0000569- Issue #2115: Important speedup in setting __slot__ attributes. Also

582
Christian Heimesf75dbef2008-02-08 00:11:31 +0000583- Fixed a minor memory leak in dictobject.c. The content of the free
584 list was not freed on interpreter shutdown.
585
Christian Heimes6075a822008-02-06 12:44:34 +0000586- Limit free list of method and builtin function objects to 256 entries
587 each.
588
Amaury Forgeot d'Arc578a8ca2008-02-04 20:53:14 +0000589- Patch #1953: Added ``sys._compact_freelists()`` and the C API functions
590 ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +0000591 to compact the internal free lists of pre-allocted ints and floats.
592
Christian Heimes951cc0f2008-01-31 23:08:23 +0000593- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.

607
Georg Brandl0cdf9a32008-01-26 14:14:20 +0000608- Patch #1473257: generator objects gain a gi_code attribute. This is the
609 same object as the func_code attribute of the function that produced the

Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +0000612- Issue #1920: "while 0" statements were completely removed by the compiler,
Vinay Sajipb7edfc42008-04-02 21:10:23 +0000613 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +0000614 the condition is false. Now the compiler correctly emits bytecode for the
615 "else" suite.
616
Guido van Rossumeead05f2008-01-24 18:21:02 +0000617- A few crashers fixed: weakref_in_del.py (issue #1377858);
618 loosing_dict_ref.py (issue #1303614, test67.py);
619 borrowed_ref_[34].py (not in tracker).
620
Vinay Sajipd7cf32e2008-01-24 12:43:33 +0000621- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +0000622 suppressed while an extension is loaded by calling SetErrorMode in
623 dynload_win.c. The error is still reported properly.
624
Christian Heimes082c9b02008-01-23 14:20:50 +0000625- Bug #1915: Python compiles with --enable-unicode=no again. However
626 several extension methods and modules do not work without unicode
627 support.
628
Georg Brandl26543b12008-01-21 18:36:51 +0000629- Issue #1882: when compiling code from a string, encoding cookies in the
630 second line of code were not always recognized correctly.
631
Georg Brandl14404b62008-01-19 19:27:05 +0000632- Issue #1679: "0x" was taken as a valid integer literal.
633
Georg Brandl6caad7d2008-01-26 14:19:22 +0000634- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +0000635 added.
636
Christian Heimesc94e2b52008-01-14 04:13:37 +0000637- sys.float_info / PyFloat_GetInfo: The floating point information
638 object was converted from a dict to a specialized structseq object.
639
Christian Heimesf31b69f2008-01-14 03:42:48 +0000640- Patch #1816: Added sys.flags structseq. It exposes the status of most
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000641 command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +0000642
Georg Brandl6caad7d2008-01-26 14:19:22 +0000643- Objects/structseq.c: Implemented new structseq representation. The patch
Christian Heimesf31b69f2008-01-14 03:42:48 +0000644 makes structseqs (e.g. the return value of os.stat) more readable.
Christian Heimes9c201962008-01-14 03:33:52 +0000645
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +0000646- Patch #1700288: added a type attribute cache that caches method accesses,
647 resulting in speedups in heavily object-oriented code.
648
Neal Norwitz3fc15b82008-01-10 05:42:58 +0000649- Bug #1776: __import__() no longer accepts filenames on any platform.
650 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +0000651
Georg Brandlaed6c662008-01-07 17:25:53 +0000652- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
653
Georg Brandl2da0fce2008-01-07 17:09:35 +0000654- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE envvar
655 and sys.dont_write_bytecode attribute. All these can be set to forbid Python
656 to attempt to write compiled bytecode files.
657
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +0000658- Improve some exception messages when Windows fails to load an extension
659 module. Now we get for example '%1 is not a valid Win32 application' instead
660 of 'error code 193'.
661
Christian Heimes8267d1d2008-01-04 00:37:34 +0000662- Bug #1481296: Fixed long(float('nan'))!=0L.
663
Christian Heimeseebb79c2008-01-03 22:32:26 +0000664- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x, y)
665 functions.
Christian Heimese2ca4242008-01-03 20:23:15 +0000666
Christian Heimes0a8143f2007-12-18 23:22:54 +0000667- Issue #1635: Platform independent creation and representation of NaN
668 and INF. float("nan"), float("inf") and float("-inf") now work on every
669 platform with IEEE 754 semantics.
670
Raymond Hettingerfd7ed402007-12-18 21:24:09 +0000671- Compiler now generates simpler and faster code for dictionary literals.
672 The oparg for BUILD_MAP now indicates an estimated dictionary size.
673 There is a new opcode, STORE_MAP, for adding entries to the dictionary.
674
Christian Heimesdb3d6cb2007-12-16 21:39:43 +0000675- Issue #1638: %zd configure test fails on Linux
676
Christian Heimes90e10e72007-12-14 02:35:23 +0000677- Issue #1620: New property decorator syntax was modifying the decorator
678 in place instead of creating a new decorator object.
679
Skip Montanaro26015492007-12-08 15:33:24 +0000680- Issue #1538: Avoid copying string in split/rsplit if the split
681 char is not found.
682
Andrew M. Kuchling395fe442007-12-05 13:27:20 +0000683- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +0000684 SystemError.
685
Nick Coghlanef01d822007-12-03 12:55:17 +0000686- PEP 366: Allow explicit relative imports when executing modules
687 inside packages with the -m switch via a new module level
688 __package__ attribute.
689
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +0000690- Issue #1402: Fix a crash on exit, when another thread is still running, and
691 if the deallocation of its frames somehow calls the PyGILState_Ensure() /
692 PyGILState_Release() functions.
693
Christian Heimes28104c52007-11-27 23:16:44 +0000694- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
695
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000696- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +0000697 attribute of an empty cell object.
698
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +0000699- Issue #1460: The utf-7 incremental decoder did not accept truncated input.
700 It now correctly saves its state between chunks of data.
701
Nick Coghlan327a39b2007-11-18 11:56:28 +0000702- Patch #1739468: Directories and zipfiles containing a __main__.py file can
703 now be directly executed by passing their name to the interpreter. The
704 directory/zipfile is automatically inserted as the first entry in sys.path.
705
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +0000706- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
707 generator expression when at the same time the executed code is closing a
708 paused generator.
709
Raymond Hettinger1760c8a2007-11-08 02:52:43 +0000710- sets and frozensets now have an isdisjoint() method.
711
Raymond Hettinger3f8caa32007-10-24 01:28:33 +0000712- optimize the performance of builtin.sum().
713
Neal Norwitz44f326e2007-10-05 05:29:17 +0000714- Fix warnings found by the new version of the Coverity checker.
715
Raymond Hettinger8f669372007-10-03 21:18:11 +0000716- The enumerate() builtin function is no longer bounded to sequences smaller
717 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
718 shifts from ints to longs.
719
Brett Cannon0b14f242007-09-30 19:45:10 +0000720- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
721 having a self-referential tuple, which is possible from C code. Nor did
722 object's tp_str consider that a type's tp_str could do something that could
723 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
724 respectively, fixed the issues.
725
Brett Cannon01531592007-09-17 03:28:34 +0000726- Issue #1164: It was possible to trigger deadlock when using the 'print'
727 statement to write to a file since the GIL was not released as needed. Now
728 PyObject_Print() does the right thing along with various tp_print
729 implementations of the built-in types and those in the collections module.
730
Brett Cannon4c20bc42007-09-11 21:02:28 +0000731- Issue #1147: Exceptions were directly allowing string exceptions in their
732 throw() method even though string exceptions no longer allowed.
733
Brett Cannona0c05512007-09-10 21:38:27 +0000734- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
735 list by using the recursion counter.
736
Brett Cannon1e534b52007-09-07 04:18:30 +0000737- Issue #1202533: Fix infinite recursion calls triggered by calls to
738 PyObject_Call() never calling back out to Python code to trigger recursion
739 depth updates/checks. Required the creation of a static RuntimeError
740 instance in case normalizing an exception put the recursion check value past
741 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
742
Martin v. Löwisa5136192007-09-04 14:19:28 +0000743- Patch #1031213: Decode source line in SyntaxErrors back to its original source
744 encoding.
745
Georg Brandl7c3b50d2007-07-12 08:38:00 +0000746- Patch #1673759: add a missing overflow check when formatting floats
747 with %G.
748
Neal Norwitzdb2b1b32007-06-11 07:36:24 +0000749- Prevent expandtabs() on string and unicode objects from causing a segfault
750 when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +0000751
Martin v. Löwisda587ab2007-06-08 17:29:20 +0000752- Bug #1733488: Fix compilation of bufferobject.c on AIX.
753
Georg Brandl25497a12007-06-01 19:20:27 +0000754- Bug #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +0000755
Neal Norwitz0ac60192007-05-27 04:08:54 +0000756- Add new attribute names for function objects. All the func_* become
757 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
758
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +0000759- Add -3 option to the interpreter to warn about features that are
760 deprecated and will be changed/removed in Python 3.0.
761
Georg Brandl2134e752007-05-21 20:34:16 +0000762- Patch #1686487: you can now pass any mapping after '**' in function
763 calls.
764
Collin Winter62903052007-05-18 23:11:24 +0000765- except clauses may now be spelled either "except E, target:" or
766 "except E as target:". This is to provide forwards compatibility with
767 Python 3.0.
768
Brett Cannon229cee22007-05-05 01:34:02 +0000769- Deprecate BaseException.message as per PEP 352.
770
Armin Rigo9790a272007-05-02 19:23:31 +0000771- Bug #1303614: don't expose object's __dict__ when the dict is
772 inherited from a builtin base.
773
Vinay Sajip8549ce32007-05-06 17:53:37 +0000774- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +0000775 setting a plain string, ie don't expand to single letter identifiers.
776
Raymond Hettinger13936692007-04-11 18:40:58 +0000777- Request #1191699: Slices can now be pickled.
778
Raymond Hettinger4db5fe92007-04-12 04:10:00 +0000779- Request #1193128: str.translate() now allows a None argument for
780 translations that only remove characters without re-mapping the
781 remaining characters.
782
Georg Brandl5cb76c12007-03-21 09:00:39 +0000783- Patch #1682205: a TypeError while unpacking an iterable is no longer
784 masked by a generic one with the message "unpack non-sequence".
785
Neal Norwitzaa754b72007-03-21 06:39:48 +0000786- Remove unused file Python/fmod.c.
787
Guido van Rossum143b5642007-03-23 04:58:42 +0000788- Bug #1683368: The object.__init__() and object.__new__() methods are
789 now stricter in rejecting excess arguments. The only time when
790 either allows excess arguments is when it is not overridden and the
791 other one is. For backwards compatibility, when both are
792 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +0000793 warning later). Also, type.__init__() insists on the same signature
794 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +0000795
Georg Brandl2b869942007-03-17 16:08:45 +0000796- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
797 to complex using its __complex__() method before falling back to the
798 __float__() method. Therefore, the functions in the cmath module now
799 can operate on objects that define a __complex__() method.
800
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +0000801- Patch #1623563: allow __class__ assignment for classes with __slots__.
802 The old and the new class are still required to have the same slot names.
803
Collin Winter77c67bd2007-03-16 04:11:30 +0000804- Patch #1642547: Fix an error/crash when encountering syntax errors in
805 complex if statements.
806
Žiga Seilnacht20f43d32007-03-15 11:44:55 +0000807- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
808 is called with an object that is faking its type.
809
Žiga Seilnacht71436f02007-03-14 12:24:09 +0000810- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
811 name.
812
Georg Brandl5240d742007-03-13 20:46:32 +0000813- Patch #1444529: the builtin compile() now accepts keyword arguments.
814
Georg Brandl7b9c5552007-03-12 14:30:05 +0000815- Bug #1678647: write a newline after printing an exception in any
816 case, even when converting the value to a string failed.
817
Georg Brandl871f1bc2007-03-12 13:17:36 +0000818- The dir() function has been extended to call the __dir__() method on
819 its argument, if it exists. If not, it will work like before. This allows
820 customizing the output of dir() in the presence of a __getattr__().
821
Collin Winter276887b2007-03-12 16:11:39 +0000822- Patch #922167: Python no longer segfaults when faced with infinitely
823 self-recursive reload() calls (as reported by bug #742342).
824
Žiga Seilnacht89032082007-03-11 15:54:54 +0000825- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
826
Collin Wintere38051d2007-03-09 20:33:07 +0000827- Patch #1491866: change the complex() constructor to allow parthensized
828 forms. This means complex(repr(x)) now works instead of raising a
829 ValueError.
830
Georg Brandlaa2321b2007-03-07 00:40:28 +0000831- Patch #703779: unset __file__ in __main__ after running a file. This
832 makes the filenames the warning module prints much more sensible when
833 a PYTHONSTARTUP file is used.
834
Georg Brandl49aafc92007-03-07 00:34:46 +0000835- Variant of patch #697613: don't exit the interpreter on a SystemExit
836 exception if the -i command line option or PYTHONINSPECT environment
837 variable is given, but break into the interactive interpreter just like
838 on other exceptions or normal program exit.
839
Georg Brandl00cd8182007-03-06 18:41:12 +0000840- Patch #1638879: don't accept strings with embedded NUL bytes in long().
841
Georg Brandl098cd692007-03-06 12:17:50 +0000842- Bug #1674503: close the file opened by execfile() in an error condition.
843
Georg Brandl0fca97a2007-03-05 22:28:08 +0000844- Patch #1674228: when assigning a slice (old-style), check for the
845 sq_ass_slice instead of the sq_slice slot.
846
Neal Norwitz88516a62007-02-26 22:41:45 +0000847- When printing an unraisable error, don't print exceptions. before the name.
848 This duplicates the behavior whening normally printing exceptions.
849
Martin v. Löwisfd963262007-02-09 12:19:32 +0000850- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
851
Brett Cannon129bd522007-01-30 21:34:36 +0000852- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
853 catch a string exception raises DeprecationWarning.
854
Brett Cannonf5bee302007-01-23 23:21:22 +0000855- Bug #1377858: Fix the segfaulting of the interpreter when an object created
856 a weakref on itself during a __del__ call for new-style classes (classic
857 classes still have the bug).
858
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000859- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
860 frame's thread state.
861
Thomas Wouters6ed19652007-01-23 13:50:49 +0000862- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
863
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000864- Prevent seg fault on shutdown which could occur if an object
865 raised a warning.
866
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000867- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
868 to avoid relying on atexit.
869
Raymond Hettinger94547f72006-12-20 06:42:06 +0000870- Bug #1590891: random.randrange don't return correct value for big number
871
Georg Brandl283a1352006-11-19 08:48:30 +0000872- Patch #1586791: Better exception messages for some operations on strings,
873 tuples and lists.
874

876
Martin v. Löwisa346c092006-11-08 06:48:36 +0000877- Bug #1591996: Correctly forward exception in instance_contains().
878
Neal Norwitz85dbec62006-11-04 19:25:22 +0000879- Bug #1588287: fix invalid assertion for `1,2` in debug builds.
880
Georg Brandlb9f4ad32006-10-29 18:31:42 +0000881- Bug #1576657: when setting a KeyError for a tuple key, make sure that
882 the tuple isn't used as the "exception arguments tuple".
883
Neal Norwitz21997af2006-10-28 21:19:07 +0000884- Bug #1565514, SystemError not raised on too many nested blocks.
885
Thomas Hellerdf08f0b2006-10-27 18:31:36 +0000886- Bug #1576174: WindowsError now displays the windows error code
887 again, no longer the posix error code.
888
Martin v. Löwisb5bc5372006-10-27 06:16:31 +0000889- Patch #1549049: Support long values in structmember, issue warnings
890 if the assigned value for structmember fields gets truncated.
891
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000892- Update the peephole optimizer to remove more dead code (jumps after returns)

1432 returned string up to the first NUL character.
1433

1819 time so that opening a database previously created with the DB_DUP or
1820 DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
1821 Specifically: dictionary assignment to a DB object will replace all
1822 values for a given key when the database allows duplicate values.
1823 DB users should use DB.put(k, v) when they want to store duplicates; not
1824 DB[k] = v.
1825

2144-----
2145
Christian Heimes5b970ad2008-02-06 13:33:44 +00002146- Unified naming convention for free lists and their limits. All free lists
2147 in Object/ are named ``free_list``, the counter ``numfree`` and the upper
2148 limit is a macro ``PyName_MAXFREELIST`` inside an #ifndef block.
2149
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00002150- ``PySet_Add()`` can now modify a newly created frozenset. Similarly to
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002151 ``PyTuple_SetItem``, it can be used to populate a brand new frozenset; but
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00002152 it does not steal a reference to the added item.
2153
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002154- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

2157 _FormatV from Python 3.0. Made PyLong_AsSsize_t and PyLong_FromSsize_t
2158 public functions.
2159
2160- Patch #1720595: add T_BOOL to the range of structmember types.
2161
2162- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
2163 ``PyFloat_GetInfo()`` to the float API.
2164
2165- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
2166 format code incorrectly truncated the length to an int, even when
2167 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
2168 results with huge strings.
2169
2170- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE
2171 and Py_REFCNT.
2172
2173- PEP 3123: Provide forward compatibility with Python 3.0, while keeping
2174 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
2175 PyVarObject_HEAD_INIT.
2176
2177- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
2178
2179- Patch #1733960: Allow T_LONGLONG to accept ints.
2180
2181- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
2182
Christian Heimes000a0742008-01-03 22:16:32 +00002183- Added a new API function ``PyImport_ImportModuleNoBlock``.
2184

2186
2187- Fix some leftovers from the conversion from int to Py_ssize_t
2188 (relevant to strings and sequences of more than 2**31 items).
2189
2190- Make _PyGILState_NoteThreadState() static, it was not used anywhere
2191 outside of pystate.c and should not be necessary.
2192
Christian Heimes000a0742008-01-03 22:16:32 +00002193- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do absolute
2194 imports. In earlier versions they might have used relative imports under
2195 some conditions.
2196
Andrew M. Kuchlingadc60ab2008-01-04 02:26:00 +00002197- Added case insensitive comparison methods ``PyOS_stricmp(char*, char*)``
Christian Heimes000a0742008-01-03 22:16:32 +00002198 and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
2199
Neal Norwitz8a267062006-08-19 04:25:29 +00002200- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx macro
2201 so it can be used as an expression.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00002207- Patch #1706: Drop support for Win9x, WinME and NT4. Python now requires
Christian Heimes95d64472008-02-09 19:55:22 +00002208 Windows 2000 or greater. The _WINVER and NTDDI_VERSION macros are set to
2209 Win2k for x86/32bit builds and WinXP for AMD64 builds.
2210
Martin v. Löwis2607e6c2006-11-21 18:20:25 +00002211- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE

Brett Cannon5e263512007-05-20 23:17:38 +00002224- Removed the macfs module. It had been deprecated since Python 2.5. This
2225 lead to the deprecation of macostools.touched() as it relied solely on macfs
2226 and was a no-op under OS X.
