Barry Warsawba437742008-04-04 01:34:41 +0000142
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +0000143- Issue #2670: Fix a failure in urllib2.build_opener(), when passed two

155 passed a value less than or equal to zero.
156
Brett Cannone9746892008-04-12 23:44:07 +0000157- Issue #1631171: Re-implement the 'warnings' module in C (the original Python
158 code has been kept as backup). This will allow for using the 'warning's
159 machinery in such places as the parser where use of pure Python code is not
Brett Cannonb457dda2008-05-02 02:25:09 +0000160 possible. Both the ``showarning()`` and ``formatwarning()`` gain an
161 optional 'line' argument which is not called by default for
Brett Cannon8a232cc2008-05-05 05:32:07 +0000162 backwards-compatibility reasons. Setting ``warnings.showwarning()`` to
163 an implementation that lacks support for the ``line`` argument will raise a
164 DeprecationWarning.

190 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +0000191
Skip Montanarob131f042008-04-18 20:35:46 +0000192- Issue #2014: Allow XML-RPC datetime objects to have dates before

194
Nick Coghlan106fc482008-04-15 10:25:31 +0000195- Issue #2439: Added new function pkgutil.get_data(), which is a

210 threads at once without fear of crashing the Python interpreter. If
211 file.close() is called while an object is in use by another thread
212 an IOError exception will be raised and the file will not be closed.
213
Thomas Hellerf7906482008-04-04 19:43:25 +0000214- The bundled libffi copy is now in sync with the recently released
215 libffi3.0.5 version, apart from some small changes to
216 Modules/_ctypes/libffi/configure.ac.
217
Fred Drake46c58c12008-04-04 05:41:30 +0000218- Issue #2385: distutils.core.run_script() makes __file__ available, so the
219 controlled environment will more closely mirror the typical script
220 environment. This supports setup.py scripts that refer to data files.
221
Barry Warsawba437742008-04-04 01:34:41 +0000222Tests
223-----
Trent Nelsone41b0062008-04-08 23:47:30 +0000224- Issue #2550: The approach used by client/server code for obtaining ports
225 to listen on in network-oriented tests has been refined in an effort to
226 facilitate running multiple instances of the entire regression test suite
227 in parallel without issue. test_support.bind_port() has been fixed such
228 that it will always return a unique port -- which wasn't always the case
229 with the previous implementation, especially if socket options had been
230 set that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
231 new implementation of bind_port() will actually raise an exception if it
232 is passed an AF_INET/SOCK_STREAM socket with either the SO_REUSEADDR or
233 SO_REUSEPORT socket option set. Furthermore, if available, bind_port()
234 will set the SO_EXCLUSIVEADDRUSE option on the socket it's been passed.
235 This currently only applies to Windows. This option prevents any other
236 sockets from binding to the host/port we've bound to, thus removing the
237 possibility of the 'non-deterministic' behaviour, as Microsoft puts it,
238 that occurs when a second SOCK_STREAM socket binds and accepts to a
239 host/port that's already been bound by another socket. The optional
240 preferred port parameter to bind_port() has been removed. Under no
241 circumstances should tests be hard coding ports!
242
243 test_support.find_unused_port() has also been introduced, which will pass
244 a temporary socket object to bind_port() in order to obtain an unused port.
245 The temporary socket object is then closed and deleted, and the port is
246 returned. This method should only be used for obtaining an unused port
247 in order to pass to an external program (i.e. the -accept [port] argument
248 to openssl's s_server mode) or as a parameter to a server-oriented class
249 that doesn't give you direct access to the underlying socket used.
250
251 Finally, test_support.HOST has been introduced, which should be used for
252 the host argument of any relevant socket calls (i.e. bind and connect).
253
254 The following tests were updated to following the new conventions:
255 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
256 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
257 test_asynchat and test_socket_ssl.
258
259 It is now possible for multiple instances of the regression test suite to
260 run in parallel without issue.

318 UTF-16 surrogates are generated in this case, like normal unicode literals
319 and the 'unicode-escape' codec.

516Core and builtins
517-----------------
518
Fred Drakea8ee94b2008-03-01 02:45:07 +0000519- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +0000520 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +0000521
Georg Brandlad61bc82008-02-23 15:11:18 +0000522- Issue #2067: file.__exit__() now calls subclasses' close() method.
523
524- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +0000525
Vinay Sajipb7edfc42008-04-02 21:10:23 +0000526- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +0000527 issue 215555 for a discussion.
528
Eric Smitha73fbe72008-02-23 03:09:44 +0000529- Added the future_builtins module, which contains hex() and oct().
530 These are the PEP 3127 version of these functions, designed to be
531 compatible with the hex() and oct() builtins from Python 3.0. They
532 differ slightly in their output formats from the existing, unchanged
533 Python 2.6 builtins. The expected usage of the future_builtins
534 module is:
535 from future_builtins import hex, oct
536
Eric Smith7ef40bf2008-02-20 23:34:22 +0000537- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
538 exponents for exponents with absolute value < 100. Follows C99
539 standard. This is a change on Windows, which would use 3 digits.
540 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
541 so that any alterations it does to the resulting string will be
542 available in stringlib/formatter.h (for float.__format__).
543
Eric Smith5a3c1352008-02-19 13:21:56 +0000544- Implemented PEP 3101, Advanced String Formatting. This adds a new
545 builtin format(); a format() method for str and unicode; a
546 __format__() method to object, str, unicode, int, long, float, and
547 datetime; the class string.Formatter; and the C API
548 PyObject_Format().
549
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +0000550- Fixed several potential crashes, all caused by specially crafted __del__
551 methods exploiting objects in temporarily inconsistent state.
552
Vinay Sajipb7edfc42008-04-02 21:10:23 +0000553- Issue #2115: Important speedup in setting __slot__ attributes. Also
554 prevent a possible crash: an Abstract Base Class would try to access a slot
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +0000555 on a registered virtual subclass.
556
Christian Heimes2f0da532008-02-15 06:57:08 +0000557- Fixed repr() and str() of complex numbers with infinity or nan as real or
558 imaginary part.
559
Andrew M. Kuchlingc6511a82008-03-04 01:48:26 +0000560- Clear all free lists during a gc.collect() of the highest generation in order
Christian Heimes3b718a72008-02-14 12:47:33 +0000561 to allow pymalloc to free more arenas. Python may give back memory to the
562 OS earlier.
563
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +0000564- Issue #2045: Fix an infinite recursion triggered when printing a subclass of
565 collections.defaultdict, if its default_factory is set to a bound method.
566
Christian Heimesf75dbef2008-02-08 00:11:31 +0000567- Fixed a minor memory leak in dictobject.c. The content of the free
568 list was not freed on interpreter shutdown.
569
Christian Heimes6075a822008-02-06 12:44:34 +0000570- Limit free list of method and builtin function objects to 256 entries
571 each.
572
Amaury Forgeot d'Arc578a8ca2008-02-04 20:53:14 +0000573- Patch #1953: Added ``sys._compact_freelists()`` and the C API functions
574 ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +0000575 to compact the internal free lists of pre-allocted ints and floats.
576
Christian Heimes951cc0f2008-01-31 23:08:23 +0000577- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
578 Python expected the return type int but the fork familie returns pi_t.
579
Mark Dickinson105be772008-01-31 22:17:37 +0000580- Issue #1678380: Fix a bug that identifies 0j and -0j when they appear
581 in the same code unit.
582

584 the collections.Sequence API.
585
Christian Heimes4d4f2702008-01-30 11:32:37 +0000586- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and linebreak
587 detection
588
Christian Heimes422051a2008-02-04 18:00:12 +0000589- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear the
Christian Heimes908caac2008-01-27 23:34:59 +0000590 internal lookup cache for ref leak tests.
591
Georg Brandl0cdf9a32008-01-26 14:14:20 +0000592- Patch #1473257: generator objects gain a gi_code attribute. This is the
593 same object as the func_code attribute of the function that produced the
594 generator.
595
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +0000596- Issue #1920: "while 0" statements were completely removed by the compiler,
Vinay Sajipb7edfc42008-04-02 21:10:23 +0000597 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +0000598 the condition is false. Now the compiler correctly emits bytecode for the
599 "else" suite.
600
Guido van Rossumeead05f2008-01-24 18:21:02 +0000601- A few crashers fixed: weakref_in_del.py (issue #1377858);
602 loosing_dict_ref.py (issue #1303614, test67.py);
603 borrowed_ref_[34].py (not in tracker).
604
Vinay Sajipd7cf32e2008-01-24 12:43:33 +0000605- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +0000606 suppressed while an extension is loaded by calling SetErrorMode in
607 dynload_win.c. The error is still reported properly.
608
Christian Heimes082c9b02008-01-23 14:20:50 +0000609- Bug #1915: Python compiles with --enable-unicode=no again. However
610 several extension methods and modules do not work without unicode
611 support.
612
Georg Brandl26543b12008-01-21 18:36:51 +0000613- Issue #1882: when compiling code from a string, encoding cookies in the
614 second line of code were not always recognized correctly.
615
Georg Brandl14404b62008-01-19 19:27:05 +0000616- Issue #1679: "0x" was taken as a valid integer literal.
617
Georg Brandl6caad7d2008-01-26 14:19:22 +0000618- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +0000619 added.
620
Christian Heimesc94e2b52008-01-14 04:13:37 +0000621- sys.float_info / PyFloat_GetInfo: The floating point information
622 object was converted from a dict to a specialized structseq object.
623
Christian Heimesf31b69f2008-01-14 03:42:48 +0000624- Patch #1816: Added sys.flags structseq. It exposes the status of most
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000625 command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +0000626
Georg Brandl6caad7d2008-01-26 14:19:22 +0000627- Objects/structseq.c: Implemented new structseq representation. The patch
Christian Heimesf31b69f2008-01-14 03:42:48 +0000628 makes structseqs (e.g. the return value of os.stat) more readable.
Christian Heimes9c201962008-01-14 03:33:52 +0000629
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +0000630- Patch #1700288: added a type attribute cache that caches method accesses,
631 resulting in speedups in heavily object-oriented code.
632
Neal Norwitz3fc15b82008-01-10 05:42:58 +0000633- Bug #1776: __import__() no longer accepts filenames on any platform.
634 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +0000635
Georg Brandlaed6c662008-01-07 17:25:53 +0000636- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
637
Georg Brandl2da0fce2008-01-07 17:09:35 +0000638- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE envvar
639 and sys.dont_write_bytecode attribute. All these can be set to forbid Python
640 to attempt to write compiled bytecode files.
641
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +0000642- Improve some exception messages when Windows fails to load an extension
643 module. Now we get for example '%1 is not a valid Win32 application' instead
644 of 'error code 193'.
645
Christian Heimes8267d1d2008-01-04 00:37:34 +0000646- Bug #1481296: Fixed long(float('nan'))!=0L.
647

649 functions.
Christian Heimese2ca4242008-01-03 20:23:15 +0000650
Christian Heimes0a8143f2007-12-18 23:22:54 +0000651- Issue #1635: Platform independent creation and representation of NaN
652 and INF. float("nan"), float("inf") and float("-inf") now work on every
653 platform with IEEE 754 semantics.
654
Raymond Hettingerfd7ed402007-12-18 21:24:09 +0000655- Compiler now generates simpler and faster code for dictionary literals.
656 The oparg for BUILD_MAP now indicates an estimated dictionary size.
657 There is a new opcode, STORE_MAP, for adding entries to the dictionary.
658
Christian Heimesdb3d6cb2007-12-16 21:39:43 +0000659- Issue #1638: %zd configure test fails on Linux
660
Christian Heimes90e10e72007-12-14 02:35:23 +0000661- Issue #1620: New property decorator syntax was modifying the decorator
662 in place instead of creating a new decorator object.
663
Skip Montanaro26015492007-12-08 15:33:24 +0000664- Issue #1538: Avoid copying string in split/rsplit if the split
665 char is not found.
666
Andrew M. Kuchling395fe442007-12-05 13:27:20 +0000667- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +0000668 SystemError.
669
Nick Coghlanef01d822007-12-03 12:55:17 +0000670- PEP 366: Allow explicit relative imports when executing modules
671 inside packages with the -m switch via a new module level
672 __package__ attribute.
673
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +0000674- Issue #1402: Fix a crash on exit, when another thread is still running, and
675 if the deallocation of its frames somehow calls the PyGILState_Ensure() /
676 PyGILState_Release() functions.
677
Christian Heimes28104c52007-11-27 23:16:44 +0000678- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
679
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000680- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +0000681 attribute of an empty cell object.
682
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +0000683- Issue #1460: The utf-7 incremental decoder did not accept truncated input.
684 It now correctly saves its state between chunks of data.
685
Nick Coghlan327a39b2007-11-18 11:56:28 +0000686- Patch #1739468: Directories and zipfiles containing a __main__.py file can
687 now be directly executed by passing their name to the interpreter. The
688 directory/zipfile is automatically inserted as the first entry in sys.path.
689
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +0000690- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
691 generator expression when at the same time the executed code is closing a
692 paused generator.
693
Raymond Hettinger1760c8a2007-11-08 02:52:43 +0000694- sets and frozensets now have an isdisjoint() method.
695
Raymond Hettinger3f8caa32007-10-24 01:28:33 +0000696- optimize the performance of builtin.sum().
697
Neal Norwitz44f326e2007-10-05 05:29:17 +0000698- Fix warnings found by the new version of the Coverity checker.
699
Raymond Hettinger8f669372007-10-03 21:18:11 +0000700- The enumerate() builtin function is no longer bounded to sequences smaller
701 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
702 shifts from ints to longs.
703
Brett Cannon0b14f242007-09-30 19:45:10 +0000704- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
705 having a self-referential tuple, which is possible from C code. Nor did
706 object's tp_str consider that a type's tp_str could do something that could
707 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
708 respectively, fixed the issues.
709
Brett Cannon01531592007-09-17 03:28:34 +0000710- Issue #1164: It was possible to trigger deadlock when using the 'print'
711 statement to write to a file since the GIL was not released as needed. Now
712 PyObject_Print() does the right thing along with various tp_print
713 implementations of the built-in types and those in the collections module.
714
Brett Cannon4c20bc42007-09-11 21:02:28 +0000715- Issue #1147: Exceptions were directly allowing string exceptions in their
716 throw() method even though string exceptions no longer allowed.
717
Brett Cannona0c05512007-09-10 21:38:27 +0000718- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
719 list by using the recursion counter.
720
Brett Cannon1e534b52007-09-07 04:18:30 +0000721- Issue #1202533: Fix infinite recursion calls triggered by calls to
722 PyObject_Call() never calling back out to Python code to trigger recursion
723 depth updates/checks. Required the creation of a static RuntimeError
724 instance in case normalizing an exception put the recursion check value past
725 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
726
Martin v. Löwisa5136192007-09-04 14:19:28 +0000727- Patch #1031213: Decode source line in SyntaxErrors back to its original source
728 encoding.
729
Georg Brandl7c3b50d2007-07-12 08:38:00 +0000730- Patch #1673759: add a missing overflow check when formatting floats
731 with %G.
732
Neal Norwitzdb2b1b32007-06-11 07:36:24 +0000733- Prevent expandtabs() on string and unicode objects from causing a segfault
734 when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +0000735
Martin v. Löwisda587ab2007-06-08 17:29:20 +0000736- Bug #1733488: Fix compilation of bufferobject.c on AIX.
737
Georg Brandl25497a12007-06-01 19:20:27 +0000738- Bug #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +0000739
Neal Norwitz0ac60192007-05-27 04:08:54 +0000740- Add new attribute names for function objects. All the func_* become
741 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
742
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +0000743- Add -3 option to the interpreter to warn about features that are
744 deprecated and will be changed/removed in Python 3.0.
745
Georg Brandl2134e752007-05-21 20:34:16 +0000746- Patch #1686487: you can now pass any mapping after '**' in function
747 calls.
748
Collin Winter62903052007-05-18 23:11:24 +0000749- except clauses may now be spelled either "except E, target:" or
750 "except E as target:". This is to provide forwards compatibility with
751 Python 3.0.
752
Brett Cannon229cee22007-05-05 01:34:02 +0000753- Deprecate BaseException.message as per PEP 352.
754
Armin Rigo9790a272007-05-02 19:23:31 +0000755- Bug #1303614: don't expose object's __dict__ when the dict is
756 inherited from a builtin base.
757
Vinay Sajip8549ce32007-05-06 17:53:37 +0000758- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +0000759 setting a plain string, ie don't expand to single letter identifiers.
760
Raymond Hettinger13936692007-04-11 18:40:58 +0000761- Request #1191699: Slices can now be pickled.
762
Raymond Hettinger4db5fe92007-04-12 04:10:00 +0000763- Request #1193128: str.translate() now allows a None argument for
764 translations that only remove characters without re-mapping the
765 remaining characters.
766
Georg Brandl5cb76c12007-03-21 09:00:39 +0000767- Patch #1682205: a TypeError while unpacking an iterable is no longer
768 masked by a generic one with the message "unpack non-sequence".
769
Neal Norwitzaa754b72007-03-21 06:39:48 +0000770- Remove unused file Python/fmod.c.
771
Guido van Rossum143b5642007-03-23 04:58:42 +0000772- Bug #1683368: The object.__init__() and object.__new__() methods are
773 now stricter in rejecting excess arguments. The only time when
774 either allows excess arguments is when it is not overridden and the
775 other one is. For backwards compatibility, when both are
776 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +0000777 warning later). Also, type.__init__() insists on the same signature
778 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +0000779
Georg Brandl2b869942007-03-17 16:08:45 +0000780- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
781 to complex using its __complex__() method before falling back to the
782 __float__() method. Therefore, the functions in the cmath module now
783 can operate on objects that define a __complex__() method.
784
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +0000785- Patch #1623563: allow __class__ assignment for classes with __slots__.
786 The old and the new class are still required to have the same slot names.
787
Collin Winter77c67bd2007-03-16 04:11:30 +0000788- Patch #1642547: Fix an error/crash when encountering syntax errors in
789 complex if statements.
790
Žiga Seilnacht20f43d32007-03-15 11:44:55 +0000791- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
792 is called with an object that is faking its type.
793
Žiga Seilnacht71436f02007-03-14 12:24:09 +0000794- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
795 name.
796
Georg Brandl5240d742007-03-13 20:46:32 +0000797- Patch #1444529: the builtin compile() now accepts keyword arguments.
798
Georg Brandl7b9c5552007-03-12 14:30:05 +0000799- Bug #1678647: write a newline after printing an exception in any
800 case, even when converting the value to a string failed.
801
Georg Brandl871f1bc2007-03-12 13:17:36 +0000802- The dir() function has been extended to call the __dir__() method on
803 its argument, if it exists. If not, it will work like before. This allows
804 customizing the output of dir() in the presence of a __getattr__().
805
Collin Winter276887b2007-03-12 16:11:39 +0000806- Patch #922167: Python no longer segfaults when faced with infinitely
807 self-recursive reload() calls (as reported by bug #742342).
808
Žiga Seilnacht89032082007-03-11 15:54:54 +0000809- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
810
Collin Wintere38051d2007-03-09 20:33:07 +0000811- Patch #1491866: change the complex() constructor to allow parthensized
812 forms. This means complex(repr(x)) now works instead of raising a
813 ValueError.
814
Georg Brandlaa2321b2007-03-07 00:40:28 +0000815- Patch #703779: unset __file__ in __main__ after running a file. This
816 makes the filenames the warning module prints much more sensible when
817 a PYTHONSTARTUP file is used.
818
Georg Brandl49aafc92007-03-07 00:34:46 +0000819- Variant of patch #697613: don't exit the interpreter on a SystemExit
820 exception if the -i command line option or PYTHONINSPECT environment
821 variable is given, but break into the interactive interpreter just like
822 on other exceptions or normal program exit.
823
Georg Brandl00cd8182007-03-06 18:41:12 +0000824- Patch #1638879: don't accept strings with embedded NUL bytes in long().
825
Georg Brandl098cd692007-03-06 12:17:50 +0000826- Bug #1674503: close the file opened by execfile() in an error condition.
827
Georg Brandl0fca97a2007-03-05 22:28:08 +0000828- Patch #1674228: when assigning a slice (old-style), check for the
829 sq_ass_slice instead of the sq_slice slot.
830
Neal Norwitz88516a62007-02-26 22:41:45 +0000831- When printing an unraisable error, don't print exceptions. before the name.
832 This duplicates the behavior whening normally printing exceptions.
833
Martin v. Löwisfd963262007-02-09 12:19:32 +0000834- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
835
Brett Cannon129bd522007-01-30 21:34:36 +0000836- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
837 catch a string exception raises DeprecationWarning.
838
Brett Cannonf5bee302007-01-23 23:21:22 +0000839- Bug #1377858: Fix the segfaulting of the interpreter when an object created
840 a weakref on itself during a __del__ call for new-style classes (classic
841 classes still have the bug).
842
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000843- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
844 frame's thread state.
845
Thomas Wouters6ed19652007-01-23 13:50:49 +0000846- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
847
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000848- Prevent seg fault on shutdown which could occur if an object
849 raised a warning.
850
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000851- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
852 to avoid relying on atexit.
853
Raymond Hettinger94547f72006-12-20 06:42:06 +0000854- Bug #1590891: random.randrange don't return correct value for big number
855
Georg Brandl283a1352006-11-19 08:48:30 +0000856- Patch #1586791: Better exception messages for some operations on strings,

862
Neal Norwitz85dbec62006-11-04 19:25:22 +0000863- Bug #1588287: fix invalid assertion for `1,2` in debug builds.
864
Georg Brandlb9f4ad32006-10-29 18:31:42 +0000865- Bug #1576657: when setting a KeyError for a tuple key, make sure that
866 the tuple isn't used as the "exception arguments tuple".
867
Neal Norwitz21997af2006-10-28 21:19:07 +0000868- Bug #1565514, SystemError not raised on too many nested blocks.
869
Thomas Hellerdf08f0b2006-10-27 18:31:36 +0000870- Bug #1576174: WindowsError now displays the windows error code
871 again, no longer the posix error code.
872
Martin v. Löwisb5bc5372006-10-27 06:16:31 +0000873- Patch #1549049: Support long values in structmember, issue warnings
874 if the assigned value for structmember fields gets truncated.
875
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000876- Update the peephole optimizer to remove more dead code (jumps after returns)
877 and inline unconditional jumps to returns.
878
Georg Brandl2c1375c2006-10-12 11:27:59 +0000879- Bug #1545497: when given an explicit base, int() did ignore NULs
880 embedded in the string to convert.
881
Georg Brandl846f73a2006-10-08 07:11:54 +0000882- Bug #1569998: break inside a try statement (outside a loop) is now
883 recognized and rejected.
884
Armin Rigo7ccbca92006-10-04 12:17:45 +0000885- list.pop(x) accepts any object x following the __index__ protocol.
886
Armin Rigo7ccbca92006-10-04 12:17:45 +0000887- A number of places, including integer negation and absolute value,
888 were fixed to not rely on undefined behaviour of the C compiler
889 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +0000890
Georg Brandl3267d282006-09-30 09:03:42 +0000891- Bug #1566800: make sure that EnvironmentError can be called with any
892 number of arguments, as was the case in Python 2.4.
893
Georg Brandl5d59c092006-09-30 08:43:30 +0000894- Patch #1567691: super() and new.instancemethod() now don't accept
895 keyword arguments any more (previously they accepted them, but didn't

1361
Georg Brandld9bef352007-03-13 19:32:21 +00001362- Patch #1533909: the timeit module now accepts callables in addition to

1407 patch #1545011.
Collin Winter22c42ba2007-03-10 02:51:26 +00001408

1416 returned string up to the first NUL character.
1417

1429 and TestSuite subclasses (not instances) are no longer accepted in

1432 later, with a more cumbersome exception.

2128-----
2129
Christian Heimes5b970ad2008-02-06 13:33:44 +00002130- Unified naming convention for free lists and their limits. All free lists
2131 in Object/ are named ``free_list``, the counter ``numfree`` and the upper
2132 limit is a macro ``PyName_MAXFREELIST`` inside an #ifndef block.
2133
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00002134- ``PySet_Add()`` can now modify a newly created frozenset. Similarly to
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002135 ``PyTuple_SetItem``, it can be used to populate a brand new frozenset; but
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00002136 it does not steal a reference to the added item.
2137
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002138- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

2141 _FormatV from Python 3.0. Made PyLong_AsSsize_t and PyLong_FromSsize_t
2142 public functions.
2143
2144- Patch #1720595: add T_BOOL to the range of structmember types.
2145
2146- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
2147 ``PyFloat_GetInfo()`` to the float API.
2148
2149- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
2150 format code incorrectly truncated the length to an int, even when
2151 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
2152 results with huge strings.
2153
2154- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE
2155 and Py_REFCNT.
2156
2157- PEP 3123: Provide forward compatibility with Python 3.0, while keeping
2158 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
2159 PyVarObject_HEAD_INIT.
2160
2161- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
2162
2163- Patch #1733960: Allow T_LONGLONG to accept ints.
2164
2165- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
2166
Christian Heimes000a0742008-01-03 22:16:32 +00002167- Added a new API function ``PyImport_ImportModuleNoBlock``.

2170
2171- Fix some leftovers from the conversion from int to Py_ssize_t
2172 (relevant to strings and sequences of more than 2**31 items).
2173
2174- Make _PyGILState_NoteThreadState() static, it was not used anywhere
2175 outside of pystate.c and should not be necessary.
2176
Christian Heimes000a0742008-01-03 22:16:32 +00002177- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do absolute
2178 imports. In earlier versions they might have used relative imports under
2179 some conditions.
2180
Andrew M. Kuchlingadc60ab2008-01-04 02:26:00 +00002181- Added case insensitive comparison methods ``PyOS_stricmp(char*, char*)``
Christian Heimes000a0742008-01-03 22:16:32 +00002182 and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
2183
Neal Norwitz8a267062006-08-19 04:25:29 +00002184- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx macro
2185 so it can be used as an expression.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00002191- Patch #1706: Drop support for Win9x, WinME and NT4. Python now requires
Christian Heimes95d64472008-02-09 19:55:22 +00002192 Windows 2000 or greater. The _WINVER and NTDDI_VERSION macros are set to
2193 Win2k for x86/32bit builds and WinXP for AMD64 builds.
2194
Martin v. Löwis2607e6c2006-11-21 18:20:25 +00002195- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE

Brett Cannon5e263512007-05-20 23:17:38 +00002208- Removed the macfs module. It had been deprecated since Python 2.5. This
2209 lead to the deprecation of macostools.touched() as it relied solely on macfs
2210 and was a no-op under OS X.
