128 passed a value less than or equal to zero.
129
Brett Cannone9746892008-04-12 23:44:07 +0000130- Issue #1631171: Re-implement the 'warnings' module in C (the original Python
131 code has been kept as backup). This will allow for using the 'warning's
132 machinery in such places as the parser where use of pure Python code is not
Brett Cannonb457dda2008-05-02 02:25:09 +0000133 possible. Both the ``showarning()`` and ``formatwarning()`` gain an
134 optional 'line' argument which is not called by default for
Brett Cannon8a232cc2008-05-05 05:32:07 +0000135 backwards-compatibility reasons. Setting ``warnings.showwarning()`` to
136 an implementation that lacks support for the ``line`` argument will raise a
137 DeprecationWarning.

163 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +0000164
Skip Montanarob131f042008-04-18 20:35:46 +0000165- Issue #2014: Allow XML-RPC datetime objects to have dates before

183 threads at once without fear of crashing the Python interpreter. If
184 file.close() is called while an object is in use by another thread
185 an IOError exception will be raised and the file will not be closed.
186
Thomas Hellerf7906482008-04-04 19:43:25 +0000187- The bundled libffi copy is now in sync with the recently released
188 libffi3.0.5 version, apart from some small changes to
189 Modules/_ctypes/libffi/configure.ac.
190
Fred Drake46c58c12008-04-04 05:41:30 +0000191- Issue #2385: distutils.core.run_script() makes __file__ available, so the
192 controlled environment will more closely mirror the typical script
193 environment. This supports setup.py scripts that refer to data files.
194
Barry Warsawba437742008-04-04 01:34:41 +0000195Tests
196-----
Trent Nelsone41b0062008-04-08 23:47:30 +0000197- Issue #2550: The approach used by client/server code for obtaining ports
198 to listen on in network-oriented tests has been refined in an effort to
199 facilitate running multiple instances of the entire regression test suite
200 in parallel without issue. test_support.bind_port() has been fixed such
201 that it will always return a unique port -- which wasn't always the case
202 with the previous implementation, especially if socket options had been
203 set that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
204 new implementation of bind_port() will actually raise an exception if it
205 is passed an AF_INET/SOCK_STREAM socket with either the SO_REUSEADDR or
206 SO_REUSEPORT socket option set. Furthermore, if available, bind_port()
207 will set the SO_EXCLUSIVEADDRUSE option on the socket it's been passed.
208 This currently only applies to Windows. This option prevents any other
209 sockets from binding to the host/port we've bound to, thus removing the
210 possibility of the 'non-deterministic' behaviour, as Microsoft puts it,
211 that occurs when a second SOCK_STREAM socket binds and accepts to a
212 host/port that's already been bound by another socket. The optional
213 preferred port parameter to bind_port() has been removed. Under no
214 circumstances should tests be hard coding ports!
215
216 test_support.find_unused_port() has also been introduced, which will pass
217 a temporary socket object to bind_port() in order to obtain an unused port.
218 The temporary socket object is then closed and deleted, and the port is
219 returned. This method should only be used for obtaining an unused port
220 in order to pass to an external program (i.e. the -accept [port] argument
221 to openssl's s_server mode) or as a parameter to a server-oriented class
222 that doesn't give you direct access to the underlying socket used.
223
224 Finally, test_support.HOST has been introduced, which should be used for
225 the host argument of any relevant socket calls (i.e. bind and connect).
226
227 The following tests were updated to following the new conventions:
228 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
229 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
230 test_asynchat and test_socket_ssl.
231
232 It is now possible for multiple instances of the regression test suite to
233 run in parallel without issue.

489Core and builtins
490-----------------
491
Fred Drakea8ee94b2008-03-01 02:45:07 +0000492- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +0000493 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +0000494
Georg Brandlad61bc82008-02-23 15:11:18 +0000495- Issue #2067: file.__exit__() now calls subclasses' close() method.
496
497- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +0000498
Vinay Sajipb7edfc42008-04-02 21:10:23 +0000499- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +0000500 issue 215555 for a discussion.
501
Eric Smitha73fbe72008-02-23 03:09:44 +0000502- Added the future_builtins module, which contains hex() and oct().
503 These are the PEP 3127 version of these functions, designed to be
504 compatible with the hex() and oct() builtins from Python 3.0. They
505 differ slightly in their output formats from the existing, unchanged
506 Python 2.6 builtins. The expected usage of the future_builtins
507 module is:
508 from future_builtins import hex, oct
509
Eric Smith7ef40bf2008-02-20 23:34:22 +0000510- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
511 exponents for exponents with absolute value < 100. Follows C99
512 standard. This is a change on Windows, which would use 3 digits.
513 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
514 so that any alterations it does to the resulting string will be
515 available in stringlib/formatter.h (for float.__format__).
516
Eric Smith5a3c1352008-02-19 13:21:56 +0000517- Implemented PEP 3101, Advanced String Formatting. This adds a new
518 builtin format(); a format() method for str and unicode; a
519 __format__() method to object, str, unicode, int, long, float, and
520 datetime; the class string.Formatter; and the C API
521 PyObject_Format().
522
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +0000523- Fixed several potential crashes, all caused by specially crafted __del__
524 methods exploiting objects in temporarily inconsistent state.
525
Vinay Sajipb7edfc42008-04-02 21:10:23 +0000526- Issue #2115: Important speedup in setting __slot__ attributes. Also
527 prevent a possible crash: an Abstract Base Class would try to access a slot
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +0000528 on a registered virtual subclass.
529
Christian Heimes2f0da532008-02-15 06:57:08 +0000530- Fixed repr() and str() of complex numbers with infinity or nan as real or
531 imaginary part.
532
Andrew M. Kuchlingc6511a82008-03-04 01:48:26 +0000533- Clear all free lists during a gc.collect() of the highest generation in order
Christian Heimes3b718a72008-02-14 12:47:33 +0000534 to allow pymalloc to free more arenas. Python may give back memory to the
535 OS earlier.
536
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +0000537- Issue #2045: Fix an infinite recursion triggered when printing a subclass of
538 collections.defaultdict, if its default_factory is set to a bound method.
539
Christian Heimesf75dbef2008-02-08 00:11:31 +0000540- Fixed a minor memory leak in dictobject.c. The content of the free
541 list was not freed on interpreter shutdown.
542
Christian Heimes6075a822008-02-06 12:44:34 +0000543- Limit free list of method and builtin function objects to 256 entries
544 each.
545
Amaury Forgeot d'Arc578a8ca2008-02-04 20:53:14 +0000546- Patch #1953: Added ``sys._compact_freelists()`` and the C API functions
547 ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +0000548 to compact the internal free lists of pre-allocted ints and floats.
549
Christian Heimes951cc0f2008-01-31 23:08:23 +0000550- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
551 Python expected the return type int but the fork familie returns pi_t.
552
Mark Dickinson105be772008-01-31 22:17:37 +0000553- Issue #1678380: Fix a bug that identifies 0j and -0j when they appear
554 in the same code unit.
555
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +0000556- Issue #2025 : Add tuple.count() and tuple.index() methods to comply with
557 the collections.Sequence API.
558
Christian Heimes4d4f2702008-01-30 11:32:37 +0000559- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and linebreak
560 detection
561
Christian Heimes422051a2008-02-04 18:00:12 +0000562- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear the
Christian Heimes908caac2008-01-27 23:34:59 +0000563 internal lookup cache for ref leak tests.
564
Georg Brandl0cdf9a32008-01-26 14:14:20 +0000565- Patch #1473257: generator objects gain a gi_code attribute. This is the
566 same object as the func_code attribute of the function that produced the
567 generator.
568
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +0000569- Issue #1920: "while 0" statements were completely removed by the compiler,
Vinay Sajipb7edfc42008-04-02 21:10:23 +0000570 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +0000571 the condition is false. Now the compiler correctly emits bytecode for the
572 "else" suite.
573
Guido van Rossumeead05f2008-01-24 18:21:02 +0000574- A few crashers fixed: weakref_in_del.py (issue #1377858);
575 loosing_dict_ref.py (issue #1303614, test67.py);
576 borrowed_ref_[34].py (not in tracker).
577
Vinay Sajipd7cf32e2008-01-24 12:43:33 +0000578- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +0000579 suppressed while an extension is loaded by calling SetErrorMode in
580 dynload_win.c. The error is still reported properly.
581
Christian Heimes082c9b02008-01-23 14:20:50 +0000582- Bug #1915: Python compiles with --enable-unicode=no again. However
583 several extension methods and modules do not work without unicode
584 support.
585
Georg Brandl26543b12008-01-21 18:36:51 +0000586- Issue #1882: when compiling code from a string, encoding cookies in the
587 second line of code were not always recognized correctly.
588
Georg Brandl14404b62008-01-19 19:27:05 +0000589- Issue #1679: "0x" was taken as a valid integer literal.
590
Georg Brandl6caad7d2008-01-26 14:19:22 +0000591- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +0000592 added.
593
Christian Heimesc94e2b52008-01-14 04:13:37 +0000594- sys.float_info / PyFloat_GetInfo: The floating point information
595 object was converted from a dict to a specialized structseq object.
596
Christian Heimesf31b69f2008-01-14 03:42:48 +0000597- Patch #1816: Added sys.flags structseq. It exposes the status of most
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000598 command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +0000599
Georg Brandl6caad7d2008-01-26 14:19:22 +0000600- Objects/structseq.c: Implemented new structseq representation. The patch
Christian Heimesf31b69f2008-01-14 03:42:48 +0000601 makes structseqs (e.g. the return value of os.stat) more readable.
Christian Heimes9c201962008-01-14 03:33:52 +0000602
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +0000603- Patch #1700288: added a type attribute cache that caches method accesses,
604 resulting in speedups in heavily object-oriented code.
605
Neal Norwitz3fc15b82008-01-10 05:42:58 +0000606- Bug #1776: __import__() no longer accepts filenames on any platform.
607 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +0000608
Georg Brandlaed6c662008-01-07 17:25:53 +0000609- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
610
Georg Brandl2da0fce2008-01-07 17:09:35 +0000611- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE envvar
612 and sys.dont_write_bytecode attribute. All these can be set to forbid Python
613 to attempt to write compiled bytecode files.
614
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +0000615- Improve some exception messages when Windows fails to load an extension
616 module. Now we get for example '%1 is not a valid Win32 application' instead
617 of 'error code 193'.
618
Christian Heimes8267d1d2008-01-04 00:37:34 +0000619- Bug #1481296: Fixed long(float('nan'))!=0L.
620
Christian Heimeseebb79c2008-01-03 22:32:26 +0000621- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x, y)
622 functions.
Christian Heimese2ca4242008-01-03 20:23:15 +0000623
Christian Heimes0a8143f2007-12-18 23:22:54 +0000624- Issue #1635: Platform independent creation and representation of NaN
625 and INF. float("nan"), float("inf") and float("-inf") now work on every
626 platform with IEEE 754 semantics.
627
Raymond Hettingerfd7ed402007-12-18 21:24:09 +0000628- Compiler now generates simpler and faster code for dictionary literals.
629 The oparg for BUILD_MAP now indicates an estimated dictionary size.
630 There is a new opcode, STORE_MAP, for adding entries to the dictionary.
631
Christian Heimesdb3d6cb2007-12-16 21:39:43 +0000632- Issue #1638: %zd configure test fails on Linux
633
Christian Heimes90e10e72007-12-14 02:35:23 +0000634- Issue #1620: New property decorator syntax was modifying the decorator
635 in place instead of creating a new decorator object.
636
Skip Montanaro26015492007-12-08 15:33:24 +0000637- Issue #1538: Avoid copying string in split/rsplit if the split
638 char is not found.
639
Andrew M. Kuchling395fe442007-12-05 13:27:20 +0000640- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +0000641 SystemError.
642
Nick Coghlanef01d822007-12-03 12:55:17 +0000643- PEP 366: Allow explicit relative imports when executing modules
644 inside packages with the -m switch via a new module level
645 __package__ attribute.
646
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +0000647- Issue #1402: Fix a crash on exit, when another thread is still running, and
648 if the deallocation of its frames somehow calls the PyGILState_Ensure() /
649 PyGILState_Release() functions.
650
Christian Heimes28104c52007-11-27 23:16:44 +0000651- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
652
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000653- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +0000654 attribute of an empty cell object.
655
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +0000656- Issue #1460: The utf-7 incremental decoder did not accept truncated input.
657 It now correctly saves its state between chunks of data.
658
Nick Coghlan327a39b2007-11-18 11:56:28 +0000659- Patch #1739468: Directories and zipfiles containing a __main__.py file can
660 now be directly executed by passing their name to the interpreter. The
661 directory/zipfile is automatically inserted as the first entry in sys.path.
662
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +0000663- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
664 generator expression when at the same time the executed code is closing a
665 paused generator.
666
Raymond Hettinger1760c8a2007-11-08 02:52:43 +0000667- sets and frozensets now have an isdisjoint() method.
668
Raymond Hettinger3f8caa32007-10-24 01:28:33 +0000669- optimize the performance of builtin.sum().
670
Neal Norwitz44f326e2007-10-05 05:29:17 +0000671- Fix warnings found by the new version of the Coverity checker.
672
Raymond Hettinger8f669372007-10-03 21:18:11 +0000673- The enumerate() builtin function is no longer bounded to sequences smaller
674 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
675 shifts from ints to longs.
676
Brett Cannon0b14f242007-09-30 19:45:10 +0000677- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
678 having a self-referential tuple, which is possible from C code. Nor did
679 object's tp_str consider that a type's tp_str could do something that could
680 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
681 respectively, fixed the issues.
682
Brett Cannon01531592007-09-17 03:28:34 +0000683- Issue #1164: It was possible to trigger deadlock when using the 'print'
684 statement to write to a file since the GIL was not released as needed. Now
685 PyObject_Print() does the right thing along with various tp_print
686 implementations of the built-in types and those in the collections module.
687
Brett Cannon4c20bc42007-09-11 21:02:28 +0000688- Issue #1147: Exceptions were directly allowing string exceptions in their
689 throw() method even though string exceptions no longer allowed.
690
Brett Cannona0c05512007-09-10 21:38:27 +0000691- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
692 list by using the recursion counter.
693
Brett Cannon1e534b52007-09-07 04:18:30 +0000694- Issue #1202533: Fix infinite recursion calls triggered by calls to
695 PyObject_Call() never calling back out to Python code to trigger recursion
696 depth updates/checks. Required the creation of a static RuntimeError
697 instance in case normalizing an exception put the recursion check value past
698 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
699
Martin v. Löwisa5136192007-09-04 14:19:28 +0000700- Patch #1031213: Decode source line in SyntaxErrors back to its original source
701 encoding.
702
Georg Brandl7c3b50d2007-07-12 08:38:00 +0000703- Patch #1673759: add a missing overflow check when formatting floats
704 with %G.
705
Neal Norwitzdb2b1b32007-06-11 07:36:24 +0000706- Prevent expandtabs() on string and unicode objects from causing a segfault
707 when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +0000708
Martin v. Löwisda587ab2007-06-08 17:29:20 +0000709- Bug #1733488: Fix compilation of bufferobject.c on AIX.
710
Georg Brandl25497a12007-06-01 19:20:27 +0000711- Bug #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +0000712
Neal Norwitz0ac60192007-05-27 04:08:54 +0000713- Add new attribute names for function objects. All the func_* become
714 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
715
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +0000716- Add -3 option to the interpreter to warn about features that are
717 deprecated and will be changed/removed in Python 3.0.
718
Georg Brandl2134e752007-05-21 20:34:16 +0000719- Patch #1686487: you can now pass any mapping after '**' in function
720 calls.
721
Collin Winter62903052007-05-18 23:11:24 +0000722- except clauses may now be spelled either "except E, target:" or
723 "except E as target:". This is to provide forwards compatibility with
724 Python 3.0.
725
Brett Cannon229cee22007-05-05 01:34:02 +0000726- Deprecate BaseException.message as per PEP 352.
727
Armin Rigo9790a272007-05-02 19:23:31 +0000728- Bug #1303614: don't expose object's __dict__ when the dict is
729 inherited from a builtin base.
730
Vinay Sajip8549ce32007-05-06 17:53:37 +0000731- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +0000732 setting a plain string, ie don't expand to single letter identifiers.
733
Raymond Hettinger13936692007-04-11 18:40:58 +0000734- Request #1191699: Slices can now be pickled.
735
Raymond Hettinger4db5fe92007-04-12 04:10:00 +0000736- Request #1193128: str.translate() now allows a None argument for
737 translations that only remove characters without re-mapping the
738 remaining characters.
739
Georg Brandl5cb76c12007-03-21 09:00:39 +0000740- Patch #1682205: a TypeError while unpacking an iterable is no longer
741 masked by a generic one with the message "unpack non-sequence".
742
Neal Norwitzaa754b72007-03-21 06:39:48 +0000743- Remove unused file Python/fmod.c.
744
Guido van Rossum143b5642007-03-23 04:58:42 +0000745- Bug #1683368: The object.__init__() and object.__new__() methods are
746 now stricter in rejecting excess arguments. The only time when
747 either allows excess arguments is when it is not overridden and the
748 other one is. For backwards compatibility, when both are
749 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +0000750 warning later). Also, type.__init__() insists on the same signature
751 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +0000752
Georg Brandl2b869942007-03-17 16:08:45 +0000753- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
754 to complex using its __complex__() method before falling back to the
755 __float__() method. Therefore, the functions in the cmath module now
756 can operate on objects that define a __complex__() method.
757
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +0000758- Patch #1623563: allow __class__ assignment for classes with __slots__.
759 The old and the new class are still required to have the same slot names.
760
Collin Winter77c67bd2007-03-16 04:11:30 +0000761- Patch #1642547: Fix an error/crash when encountering syntax errors in
762 complex if statements.
763
Žiga Seilnacht20f43d32007-03-15 11:44:55 +0000764- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
765 is called with an object that is faking its type.
766
Žiga Seilnacht71436f02007-03-14 12:24:09 +0000767- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
768 name.
769
Georg Brandl5240d742007-03-13 20:46:32 +0000770- Patch #1444529: the builtin compile() now accepts keyword arguments.
771
Georg Brandl7b9c5552007-03-12 14:30:05 +0000772- Bug #1678647: write a newline after printing an exception in any
773 case, even when converting the value to a string failed.
774
Georg Brandl871f1bc2007-03-12 13:17:36 +0000775- The dir() function has been extended to call the __dir__() method on
776 its argument, if it exists. If not, it will work like before. This allows
777 customizing the output of dir() in the presence of a __getattr__().
778
Collin Winter276887b2007-03-12 16:11:39 +0000779- Patch #922167: Python no longer segfaults when faced with infinitely
780 self-recursive reload() calls (as reported by bug #742342).
781
Žiga Seilnacht89032082007-03-11 15:54:54 +0000782- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
783
Collin Wintere38051d2007-03-09 20:33:07 +0000784- Patch #1491866: change the complex() constructor to allow parthensized
785 forms. This means complex(repr(x)) now works instead of raising a
786 ValueError.
787
Georg Brandlaa2321b2007-03-07 00:40:28 +0000788- Patch #703779: unset __file__ in __main__ after running a file. This
789 makes the filenames the warning module prints much more sensible when
790 a PYTHONSTARTUP file is used.
791
Georg Brandl49aafc92007-03-07 00:34:46 +0000792- Variant of patch #697613: don't exit the interpreter on a SystemExit
793 exception if the -i command line option or PYTHONINSPECT environment
794 variable is given, but break into the interactive interpreter just like
795 on other exceptions or normal program exit.
796
Georg Brandl00cd8182007-03-06 18:41:12 +0000797- Patch #1638879: don't accept strings with embedded NUL bytes in long().
798
Georg Brandl098cd692007-03-06 12:17:50 +0000799- Bug #1674503: close the file opened by execfile() in an error condition.
800
Georg Brandl0fca97a2007-03-05 22:28:08 +0000801- Patch #1674228: when assigning a slice (old-style), check for the
802 sq_ass_slice instead of the sq_slice slot.
803
Neal Norwitz88516a62007-02-26 22:41:45 +0000804- When printing an unraisable error, don't print exceptions. before the name.
805 This duplicates the behavior whening normally printing exceptions.
806
Martin v. Löwisfd963262007-02-09 12:19:32 +0000807- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
808
Brett Cannon129bd522007-01-30 21:34:36 +0000809- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
810 catch a string exception raises DeprecationWarning.
811
Brett Cannonf5bee302007-01-23 23:21:22 +0000812- Bug #1377858: Fix the segfaulting of the interpreter when an object created
813 a weakref on itself during a __del__ call for new-style classes (classic
814 classes still have the bug).
815
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000816- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
817 frame's thread state.
818
Thomas Wouters6ed19652007-01-23 13:50:49 +0000819- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
820
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000821- Prevent seg fault on shutdown which could occur if an object
822 raised a warning.
823
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000824- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
825 to avoid relying on atexit.
826
Raymond Hettinger94547f72006-12-20 06:42:06 +0000827- Bug #1590891: random.randrange don't return correct value for big number
828
Georg Brandl283a1352006-11-19 08:48:30 +0000829- Patch #1586791: Better exception messages for some operations on strings,
830 tuples and lists.
831

835
Neal Norwitz85dbec62006-11-04 19:25:22 +0000836- Bug #1588287: fix invalid assertion for `1,2` in debug builds.
837
Georg Brandlb9f4ad32006-10-29 18:31:42 +0000838- Bug #1576657: when setting a KeyError for a tuple key, make sure that
839 the tuple isn't used as the "exception arguments tuple".
840
Neal Norwitz21997af2006-10-28 21:19:07 +0000841- Bug #1565514, SystemError not raised on too many nested blocks.
842
Thomas Hellerdf08f0b2006-10-27 18:31:36 +0000843- Bug #1576174: WindowsError now displays the windows error code
844 again, no longer the posix error code.
845
Martin v. Löwisb5bc5372006-10-27 06:16:31 +0000846- Patch #1549049: Support long values in structmember, issue warnings
847 if the assigned value for structmember fields gets truncated.
848
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000849- Update the peephole optimizer to remove more dead code (jumps after returns)
850 and inline unconditional jumps to returns.
851
Georg Brandl2c1375c2006-10-12 11:27:59 +0000852- Bug #1545497: when given an explicit base, int() did ignore NULs
853 embedded in the string to convert.
854
Georg Brandl846f73a2006-10-08 07:11:54 +0000855- Bug #1569998: break inside a try statement (outside a loop) is now
856 recognized and rejected.
857
Armin Rigo7ccbca92006-10-04 12:17:45 +0000858- list.pop(x) accepts any object x following the __index__ protocol.
859
Armin Rigo7ccbca92006-10-04 12:17:45 +0000860- A number of places, including integer negation and absolute value,
861 were fixed to not rely on undefined behaviour of the C compiler
862 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +0000863
Georg Brandl3267d282006-09-30 09:03:42 +0000864- Bug #1566800: make sure that EnvironmentError can be called with any
865 number of arguments, as was the case in Python 2.4.
866
Georg Brandl5d59c092006-09-30 08:43:30 +0000867- Patch #1567691: super() and new.instancemethod() now don't accept
868 keyword arguments any more (previously they accepted them, but didn't
869 use them).
870
Georg Brandla10d3af2006-09-24 12:35:36 +0000871- Fix a bug in the parser's future statement handling that led to "with"
872 not being recognized as a keyword after, e.g., this statement:
873 from __future__ import division, with_statement
874
Neal Norwitz3a230172006-09-22 08:18:10 +0000875- Bug #1557232: fix seg fault with def f((((x)))) and def f(((x),)).
876

878
Brett Cannonf6aa86e2006-09-20 18:43:13 +0000879- Allow exception instances to be directly sliced again.
880
Brett Cannon9adeab72006-09-20 18:34:28 +0000881- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
882 allows calling unicode() on exceptions classes directly to succeed.
883
Georg Brandl4e933132006-09-06 20:05:58 +0000884- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
885 Also make sure that every exception class has __module__ set to
886 'exceptions'.
887
Georg Brandl98775df2006-09-06 06:09:31 +0000888- Bug #1550983: emit better error messages for erroneous relative
889 imports (if not in package and if beyond toplevel package).
890
Tim Petersc10c9d02006-09-05 02:18:09 +0000891- Overflow checking code in integer division ran afoul of new gcc
892 optimizations. Changed to be more standard-conforming.

1389 returned string up to the first NUL character.

1450 relative directory names.
1451

1776 time so that opening a database previously created with the DB_DUP or
1777 DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
1778 Specifically: dictionary assignment to a DB object will replace all
1779 values for a given key when the database allows duplicate values.
1780 DB users should use DB.put(k, v) when they want to store duplicates; not
1781 DB[k] = v.

2101-----
2102
Christian Heimes5b970ad2008-02-06 13:33:44 +00002103- Unified naming convention for free lists and their limits. All free lists
2104 in Object/ are named ``free_list``, the counter ``numfree`` and the upper
2105 limit is a macro ``PyName_MAXFREELIST`` inside an #ifndef block.
2106
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00002107- ``PySet_Add()`` can now modify a newly created frozenset. Similarly to
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002108 ``PyTuple_SetItem``, it can be used to populate a brand new frozenset; but
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00002109 it does not steal a reference to the added item.
2110
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002111- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl6caad7d2008-01-26 14:19:22 +00002113- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format and
2114 _FormatV from Python 3.0. Made PyLong_AsSsize_t and PyLong_FromSsize_t
2115 public functions.
2116
2117- Patch #1720595: add T_BOOL to the range of structmember types.
2118
2119- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
2120 ``PyFloat_GetInfo()`` to the float API.
2121
2122- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
2123 format code incorrectly truncated the length to an int, even when
2124 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
2125 results with huge strings.
2126
2127- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE
2128 and Py_REFCNT.
2129
2130- PEP 3123: Provide forward compatibility with Python 3.0, while keeping
2131 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
2132 PyVarObject_HEAD_INIT.
2133
2134- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
2135
2136- Patch #1733960: Allow T_LONGLONG to accept ints.
2137
2138- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
2139
Christian Heimes000a0742008-01-03 22:16:32 +00002140- Added a new API function ``PyImport_ImportModuleNoBlock``.
2141
Georg Brandl6caad7d2008-01-26 14:19:22 +00002142- Bug #1637022: Prefix AST symbols with _Py_.
2143
2144- Fix some leftovers from the conversion from int to Py_ssize_t
2145 (relevant to strings and sequences of more than 2**31 items).
2146
2147- Make _PyGILState_NoteThreadState() static, it was not used anywhere
2148 outside of pystate.c and should not be necessary.
2149
Christian Heimes000a0742008-01-03 22:16:32 +00002150- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do absolute
2151 imports. In earlier versions they might have used relative imports under
2152 some conditions.
2153
Andrew M. Kuchlingadc60ab2008-01-04 02:26:00 +00002154- Added case insensitive comparison methods ``PyOS_stricmp(char*, char*)``
Christian Heimes000a0742008-01-03 22:16:32 +00002155 and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
2156
Neal Norwitz8a267062006-08-19 04:25:29 +00002157- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx macro
2158 so it can be used as an expression.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00002164- Patch #1706: Drop support for Win9x, WinME and NT4. Python now requires
Christian Heimes95d64472008-02-09 19:55:22 +00002165 Windows 2000 or greater. The _WINVER and NTDDI_VERSION macros are set to
2166 Win2k for x86/32bit builds and WinXP for AMD64 builds.
2167
Martin v. Löwis2607e6c2006-11-21 18:20:25 +00002168- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE

Brett Cannon5e263512007-05-20 23:17:38 +00002181- Removed the macfs module. It had been deprecated since Python 2.5. This
2182 lead to the deprecation of macostools.touched() as it relied solely on macfs
2183 and was a no-op under OS X.
