Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +0000180- Issue #2670: Fix a failure in urllib2.build_opener(), when passed two
181 handlers that derive the same default base class.
182

192 passed a value less than or equal to zero.
193
Brett Cannone9746892008-04-12 23:44:07 +0000194- Issue #1631171: Re-implement the 'warnings' module in C (the original Python
195 code has been kept as backup). This will allow for using the 'warning's
196 machinery in such places as the parser where use of pure Python code is not
Brett Cannonb457dda2008-05-02 02:25:09 +0000197 possible. Both the ``showarning()`` and ``formatwarning()`` gain an
198 optional 'line' argument which is not called by default for
Brett Cannon8a232cc2008-05-05 05:32:07 +0000199 backwards-compatibility reasons. Setting ``warnings.showwarning()`` to
200 an implementation that lacks support for the ``line`` argument will raise a
201 DeprecationWarning.

224
Gregory P. Smithd59fefb2008-04-22 08:11:33 +0000225- The getpass module has been improved on Unix. It now uses /dev/tty
226 by default and uses stderr instead of stdout. A GetPassWarning is
227 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +0000228
Skip Montanarob131f042008-04-18 20:35:46 +0000229- Issue #2014: Allow XML-RPC datetime objects to have dates before

231
Nick Coghlan106fc482008-04-15 10:25:31 +0000232- Issue #2439: Added new function pkgutil.get_data(), which is a
233 convenience wrapper for the PEP 302 get_data() API.
234

247 threads at once without fear of crashing the Python interpreter. If
248 file.close() is called while an object is in use by another thread
249 an IOError exception will be raised and the file will not be closed.
250
Thomas Hellerf7906482008-04-04 19:43:25 +0000251- The bundled libffi copy is now in sync with the recently released
252 libffi3.0.5 version, apart from some small changes to
253 Modules/_ctypes/libffi/configure.ac.
254
Fred Drake46c58c12008-04-04 05:41:30 +0000255- Issue #2385: distutils.core.run_script() makes __file__ available, so the
256 controlled environment will more closely mirror the typical script
257 environment. This supports setup.py scripts that refer to data files.
258
Barry Warsawba437742008-04-04 01:34:41 +0000259Tests
260-----
Trent Nelsone41b0062008-04-08 23:47:30 +0000261- Issue #2550: The approach used by client/server code for obtaining ports
262 to listen on in network-oriented tests has been refined in an effort to
263 facilitate running multiple instances of the entire regression test suite
264 in parallel without issue. test_support.bind_port() has been fixed such
265 that it will always return a unique port -- which wasn't always the case
266 with the previous implementation, especially if socket options had been
267 set that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
268 new implementation of bind_port() will actually raise an exception if it
269 is passed an AF_INET/SOCK_STREAM socket with either the SO_REUSEADDR or
270 SO_REUSEPORT socket option set. Furthermore, if available, bind_port()
271 will set the SO_EXCLUSIVEADDRUSE option on the socket it's been passed.
272 This currently only applies to Windows. This option prevents any other
273 sockets from binding to the host/port we've bound to, thus removing the
274 possibility of the 'non-deterministic' behaviour, as Microsoft puts it,
275 that occurs when a second SOCK_STREAM socket binds and accepts to a
276 host/port that's already been bound by another socket. The optional
277 preferred port parameter to bind_port() has been removed. Under no
278 circumstances should tests be hard coding ports!
279
280 test_support.find_unused_port() has also been introduced, which will pass
281 a temporary socket object to bind_port() in order to obtain an unused port.
282 The temporary socket object is then closed and deleted, and the port is
283 returned. This method should only be used for obtaining an unused port
284 in order to pass to an external program (i.e. the -accept [port] argument
285 to openssl's s_server mode) or as a parameter to a server-oriented class
286 that doesn't give you direct access to the underlying socket used.
287
288 Finally, test_support.HOST has been introduced, which should be used for
289 the host argument of any relevant socket calls (i.e. bind and connect).
290
291 The following tests were updated to following the new conventions:
292 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
293 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
294 test_asynchat and test_socket_ssl.
295
296 It is now possible for multiple instances of the regression test suite to
297 run in parallel without issue.

567 These are the PEP 3127 version of these functions, designed to be
568 compatible with the hex() and oct() builtins from Python 3.0. They
569 differ slightly in their output formats from the existing, unchanged
570 Python 2.6 builtins. The expected usage of the future_builtins
571 module is:
572 from future_builtins import hex, oct
573
Eric Smith7ef40bf2008-02-20 23:34:22 +0000574- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
575 exponents for exponents with absolute value < 100. Follows C99
576 standard. This is a change on Windows, which would use 3 digits.
577 Also, added 'n' to the formats that PyOS_ascii_formatd understands,

611 ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +0000612 to compact the internal free lists of pre-allocted ints and floats.
613
Christian Heimes951cc0f2008-01-31 23:08:23 +0000614- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
615 Python expected the return type int but the fork familie returns pi_t.
616
Mark Dickinson105be772008-01-31 22:17:37 +0000617- Issue #1678380: Fix a bug that identifies 0j and -0j when they appear
618 in the same code unit.
619
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +0000620- Issue #2025 : Add tuple.count() and tuple.index() methods to comply with
621 the collections.Sequence API.
622
Christian Heimes4d4f2702008-01-30 11:32:37 +0000623- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and linebreak
624 detection
625
Christian Heimes422051a2008-02-04 18:00:12 +0000626- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear the
Christian Heimes908caac2008-01-27 23:34:59 +0000627 internal lookup cache for ref leak tests.
628
Georg Brandl0cdf9a32008-01-26 14:14:20 +0000629- Patch #1473257: generator objects gain a gi_code attribute. This is the
630 same object as the func_code attribute of the function that produced the
631 generator.
632
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +0000633- Issue #1920: "while 0" statements were completely removed by the compiler,
Vinay Sajipb7edfc42008-04-02 21:10:23 +0000634 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +0000635 the condition is false. Now the compiler correctly emits bytecode for the
636 "else" suite.
637
Guido van Rossumeead05f2008-01-24 18:21:02 +0000638- A few crashers fixed: weakref_in_del.py (issue #1377858);
639 loosing_dict_ref.py (issue #1303614, test67.py);
640 borrowed_ref_[34].py (not in tracker).
641
Vinay Sajipd7cf32e2008-01-24 12:43:33 +0000642- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +0000643 suppressed while an extension is loaded by calling SetErrorMode in
644 dynload_win.c. The error is still reported properly.
645
Christian Heimes082c9b02008-01-23 14:20:50 +0000646- Bug #1915: Python compiles with --enable-unicode=no again. However
647 several extension methods and modules do not work without unicode
648 support.
649
Georg Brandl26543b12008-01-21 18:36:51 +0000650- Issue #1882: when compiling code from a string, encoding cookies in the
651 second line of code were not always recognized correctly.
652
Georg Brandl14404b62008-01-19 19:27:05 +0000653- Issue #1679: "0x" was taken as a valid integer literal.
654
Georg Brandl6caad7d2008-01-26 14:19:22 +0000655- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +0000656 added.
657
Christian Heimesc94e2b52008-01-14 04:13:37 +0000658- sys.float_info / PyFloat_GetInfo: The floating point information
659 object was converted from a dict to a specialized structseq object.
660
Christian Heimesf31b69f2008-01-14 03:42:48 +0000661- Patch #1816: Added sys.flags structseq. It exposes the status of most
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000662 command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +0000663
Georg Brandl6caad7d2008-01-26 14:19:22 +0000664- Objects/structseq.c: Implemented new structseq representation. The patch
Christian Heimesf31b69f2008-01-14 03:42:48 +0000665 makes structseqs (e.g. the return value of os.stat) more readable.
Christian Heimes9c201962008-01-14 03:33:52 +0000666
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +0000667- Patch #1700288: added a type attribute cache that caches method accesses,
668 resulting in speedups in heavily object-oriented code.
669
Neal Norwitz3fc15b82008-01-10 05:42:58 +0000670- Bug #1776: __import__() no longer accepts filenames on any platform.
671 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +0000672
Georg Brandlaed6c662008-01-07 17:25:53 +0000673- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
674
Georg Brandl2da0fce2008-01-07 17:09:35 +0000675- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE envvar
676 and sys.dont_write_bytecode attribute. All these can be set to forbid Python
677 to attempt to write compiled bytecode files.
678
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +0000679- Improve some exception messages when Windows fails to load an extension
680 module. Now we get for example '%1 is not a valid Win32 application' instead
681 of 'error code 193'.
682
Christian Heimes8267d1d2008-01-04 00:37:34 +0000683- Bug #1481296: Fixed long(float('nan'))!=0L.
684
Christian Heimeseebb79c2008-01-03 22:32:26 +0000685- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x, y)
686 functions.
Christian Heimese2ca4242008-01-03 20:23:15 +0000687
Christian Heimes0a8143f2007-12-18 23:22:54 +0000688- Issue #1635: Platform independent creation and representation of NaN
689 and INF. float("nan"), float("inf") and float("-inf") now work on every
690 platform with IEEE 754 semantics.
691
Raymond Hettingerfd7ed402007-12-18 21:24:09 +0000692- Compiler now generates simpler and faster code for dictionary literals.
693 The oparg for BUILD_MAP now indicates an estimated dictionary size.
694 There is a new opcode, STORE_MAP, for adding entries to the dictionary.
695
Christian Heimesdb3d6cb2007-12-16 21:39:43 +0000696- Issue #1638: %zd configure test fails on Linux
697
Christian Heimes90e10e72007-12-14 02:35:23 +0000698- Issue #1620: New property decorator syntax was modifying the decorator
699 in place instead of creating a new decorator object.
700
Skip Montanaro26015492007-12-08 15:33:24 +0000701- Issue #1538: Avoid copying string in split/rsplit if the split
702 char is not found.
703
Andrew M. Kuchling395fe442007-12-05 13:27:20 +0000704- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +0000705 SystemError.
706
Nick Coghlanef01d822007-12-03 12:55:17 +0000707- PEP 366: Allow explicit relative imports when executing modules
708 inside packages with the -m switch via a new module level
709 __package__ attribute.
710
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +0000711- Issue #1402: Fix a crash on exit, when another thread is still running, and
712 if the deallocation of its frames somehow calls the PyGILState_Ensure() /
713 PyGILState_Release() functions.
714
Christian Heimes28104c52007-11-27 23:16:44 +0000715- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
716
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000717- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +0000718 attribute of an empty cell object.
719
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +0000720- Issue #1460: The utf-7 incremental decoder did not accept truncated input.
721 It now correctly saves its state between chunks of data.
722
Nick Coghlan327a39b2007-11-18 11:56:28 +0000723- Patch #1739468: Directories and zipfiles containing a __main__.py file can
724 now be directly executed by passing their name to the interpreter. The
725 directory/zipfile is automatically inserted as the first entry in sys.path.
726
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +0000727- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
728 generator expression when at the same time the executed code is closing a
729 paused generator.
730
Raymond Hettinger1760c8a2007-11-08 02:52:43 +0000731- sets and frozensets now have an isdisjoint() method.
732
Raymond Hettinger3f8caa32007-10-24 01:28:33 +0000733- optimize the performance of builtin.sum().
734
Neal Norwitz44f326e2007-10-05 05:29:17 +0000735- Fix warnings found by the new version of the Coverity checker.
736
Raymond Hettinger8f669372007-10-03 21:18:11 +0000737- The enumerate() builtin function is no longer bounded to sequences smaller
738 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
739 shifts from ints to longs.
740
Brett Cannon0b14f242007-09-30 19:45:10 +0000741- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
742 having a self-referential tuple, which is possible from C code. Nor did
743 object's tp_str consider that a type's tp_str could do something that could
744 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
745 respectively, fixed the issues.
746
Brett Cannon01531592007-09-17 03:28:34 +0000747- Issue #1164: It was possible to trigger deadlock when using the 'print'
748 statement to write to a file since the GIL was not released as needed. Now
749 PyObject_Print() does the right thing along with various tp_print
750 implementations of the built-in types and those in the collections module.
751
Brett Cannon4c20bc42007-09-11 21:02:28 +0000752- Issue #1147: Exceptions were directly allowing string exceptions in their
753 throw() method even though string exceptions no longer allowed.
754
Brett Cannona0c05512007-09-10 21:38:27 +0000755- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
756 list by using the recursion counter.
757
Brett Cannon1e534b52007-09-07 04:18:30 +0000758- Issue #1202533: Fix infinite recursion calls triggered by calls to
759 PyObject_Call() never calling back out to Python code to trigger recursion
760 depth updates/checks. Required the creation of a static RuntimeError
761 instance in case normalizing an exception put the recursion check value past
762 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
763
Martin v. Löwisa5136192007-09-04 14:19:28 +0000764- Patch #1031213: Decode source line in SyntaxErrors back to its original source
765 encoding.
766
Georg Brandl7c3b50d2007-07-12 08:38:00 +0000767- Patch #1673759: add a missing overflow check when formatting floats
768 with %G.
769
Neal Norwitzdb2b1b32007-06-11 07:36:24 +0000770- Prevent expandtabs() on string and unicode objects from causing a segfault
771 when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +0000772
Martin v. Löwisda587ab2007-06-08 17:29:20 +0000773- Bug #1733488: Fix compilation of bufferobject.c on AIX.
774
Georg Brandl25497a12007-06-01 19:20:27 +0000775- Bug #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +0000776
Neal Norwitz0ac60192007-05-27 04:08:54 +0000777- Add new attribute names for function objects. All the func_* become
778 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
779
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +0000780- Add -3 option to the interpreter to warn about features that are
781 deprecated and will be changed/removed in Python 3.0.
782
Georg Brandl2134e752007-05-21 20:34:16 +0000783- Patch #1686487: you can now pass any mapping after '**' in function
784 calls.
785
Collin Winter62903052007-05-18 23:11:24 +0000786- except clauses may now be spelled either "except E, target:" or
787 "except E as target:". This is to provide forwards compatibility with
788 Python 3.0.
789
Brett Cannon229cee22007-05-05 01:34:02 +0000790- Deprecate BaseException.message as per PEP 352.
791
Armin Rigo9790a272007-05-02 19:23:31 +0000792- Bug #1303614: don't expose object's __dict__ when the dict is
793 inherited from a builtin base.
794
Vinay Sajip8549ce32007-05-06 17:53:37 +0000795- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +0000796 setting a plain string, ie don't expand to single letter identifiers.
797
Raymond Hettinger13936692007-04-11 18:40:58 +0000798- Request #1191699: Slices can now be pickled.
799
Raymond Hettinger4db5fe92007-04-12 04:10:00 +0000800- Request #1193128: str.translate() now allows a None argument for
801 translations that only remove characters without re-mapping the
802 remaining characters.
803
Georg Brandl5cb76c12007-03-21 09:00:39 +0000804- Patch #1682205: a TypeError while unpacking an iterable is no longer
805 masked by a generic one with the message "unpack non-sequence".
806
Neal Norwitzaa754b72007-03-21 06:39:48 +0000807- Remove unused file Python/fmod.c.
808
Guido van Rossum143b5642007-03-23 04:58:42 +0000809- Bug #1683368: The object.__init__() and object.__new__() methods are
810 now stricter in rejecting excess arguments. The only time when
811 either allows excess arguments is when it is not overridden and the
812 other one is. For backwards compatibility, when both are
813 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +0000814 warning later). Also, type.__init__() insists on the same signature
815 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +0000816
Georg Brandl2b869942007-03-17 16:08:45 +0000817- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
818 to complex using its __complex__() method before falling back to the
819 __float__() method. Therefore, the functions in the cmath module now
820 can operate on objects that define a __complex__() method.
821
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +0000822- Patch #1623563: allow __class__ assignment for classes with __slots__.
823 The old and the new class are still required to have the same slot names.
824
Collin Winter77c67bd2007-03-16 04:11:30 +0000825- Patch #1642547: Fix an error/crash when encountering syntax errors in
826 complex if statements.
827
Žiga Seilnacht20f43d32007-03-15 11:44:55 +0000828- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
829 is called with an object that is faking its type.
830
Žiga Seilnacht71436f02007-03-14 12:24:09 +0000831- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
832 name.
833
Georg Brandl5240d742007-03-13 20:46:32 +0000834- Patch #1444529: the builtin compile() now accepts keyword arguments.
835
Georg Brandl7b9c5552007-03-12 14:30:05 +0000836- Bug #1678647: write a newline after printing an exception in any
837 case, even when converting the value to a string failed.
838
Georg Brandl871f1bc2007-03-12 13:17:36 +0000839- The dir() function has been extended to call the __dir__() method on
840 its argument, if it exists. If not, it will work like before. This allows
841 customizing the output of dir() in the presence of a __getattr__().
842
Collin Winter276887b2007-03-12 16:11:39 +0000843- Patch #922167: Python no longer segfaults when faced with infinitely
844 self-recursive reload() calls (as reported by bug #742342).
845
Žiga Seilnacht89032082007-03-11 15:54:54 +0000846- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
847
Collin Wintere38051d2007-03-09 20:33:07 +0000848- Patch #1491866: change the complex() constructor to allow parthensized
849 forms. This means complex(repr(x)) now works instead of raising a
850 ValueError.
851
Georg Brandlaa2321b2007-03-07 00:40:28 +0000852- Patch #703779: unset __file__ in __main__ after running a file. This
853 makes the filenames the warning module prints much more sensible when
854 a PYTHONSTARTUP file is used.
855
Georg Brandl49aafc92007-03-07 00:34:46 +0000856- Variant of patch #697613: don't exit the interpreter on a SystemExit
857 exception if the -i command line option or PYTHONINSPECT environment
858 variable is given, but break into the interactive interpreter just like
859 on other exceptions or normal program exit.
860
Georg Brandl00cd8182007-03-06 18:41:12 +0000861- Patch #1638879: don't accept strings with embedded NUL bytes in long().
862
Georg Brandl098cd692007-03-06 12:17:50 +0000863- Bug #1674503: close the file opened by execfile() in an error condition.
864
Georg Brandl0fca97a2007-03-05 22:28:08 +0000865- Patch #1674228: when assigning a slice (old-style), check for the
866 sq_ass_slice instead of the sq_slice slot.
867
Neal Norwitz88516a62007-02-26 22:41:45 +0000868- When printing an unraisable error, don't print exceptions. before the name.
869 This duplicates the behavior whening normally printing exceptions.
870
Martin v. Löwisfd963262007-02-09 12:19:32 +0000871- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
872
Brett Cannon129bd522007-01-30 21:34:36 +0000873- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
874 catch a string exception raises DeprecationWarning.
875
Brett Cannonf5bee302007-01-23 23:21:22 +0000876- Bug #1377858: Fix the segfaulting of the interpreter when an object created
877 a weakref on itself during a __del__ call for new-style classes (classic
878 classes still have the bug).
879
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000880- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
881 frame's thread state.
882
Thomas Wouters6ed19652007-01-23 13:50:49 +0000883- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
884
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000885- Prevent seg fault on shutdown which could occur if an object
886 raised a warning.
887
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000888- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
889 to avoid relying on atexit.
890

Gregory P. Smith2b3ba582008-01-17 08:03:17 +00001742 RFC 3207 and forgets any knowledge obtained from the server not obtained
1743 from the TLS negotiation itself. Patch contributed by Bill Fenner.
1744
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00001745- Issue1339: The smtplib.SMTP class has been refactored a bit such
1746 that the SMTP.starttls() caller no longer needs to call ehlo()

1840 time so that opening a database previously created with the DB_DUP or
1841 DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
1842 Specifically: dictionary assignment to a DB object will replace all
1843 values for a given key when the database allows duplicate values.
1844 DB users should use DB.put(k, v) when they want to store duplicates; not
1845 DB[k] = v.
1846
Gregory P. Smithac11e022007-11-05 02:56:31 +00001847- Add the bsddb.db.DBEnv.lock_id_free method.

2170
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00002171- ``PySet_Add()`` can now modify a newly created frozenset. Similarly to
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002172 ``PyTuple_SetItem``, it can be used to populate a brand new frozenset; but
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00002173 it does not steal a reference to the added item.
2174
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002175- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

2182
2183- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
2184 ``PyFloat_GetInfo()`` to the float API.
2185
2186- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
2187 format code incorrectly truncated the length to an int, even when
2188 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
2189 results with huge strings.
2190
2191- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE
2192 and Py_REFCNT.
2193
2194- PEP 3123: Provide forward compatibility with Python 3.0, while keeping
2195 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and

2197
2198- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
2199
2200- Patch #1733960: Allow T_LONGLONG to accept ints.
2201
2202- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.

2207
2208- Fix some leftovers from the conversion from int to Py_ssize_t
2209 (relevant to strings and sequences of more than 2**31 items).
2210
2211- Make _PyGILState_NoteThreadState() static, it was not used anywhere
2212 outside of pystate.c and should not be necessary.
2213
Christian Heimes000a0742008-01-03 22:16:32 +00002214- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do absolute
2215 imports. In earlier versions they might have used relative imports under
2216 some conditions.
2217
Andrew M. Kuchlingadc60ab2008-01-04 02:26:00 +00002218- Added case insensitive comparison methods ``PyOS_stricmp(char*, char*)``
Christian Heimes000a0742008-01-03 22:16:32 +00002219 and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
