204
Andrew M. Kuchling46d6b682008-04-30 16:19:55 +0000205Extension Modules
206-----------------
Barry Warsawba437742008-04-04 01:34:41 +0000207
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +0000208- Issue #2670: Fix a failure in urllib2.build_opener(), when passed two
209 handlers that derive the same default base class.
210
Christian Heimese74c8f22008-04-19 02:23:57 +0000211- Added kill, terminate and send_signal(sig) to subprocess.Popen.
212
Christian Heimes6f341092008-04-18 23:13:07 +0000213- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to the cmath
214 module.
215
216- Four new methods were added to the math and cmath modules:
217 acosh, asinh, atanh and log1p.
218
Gregory P. Smith671c5d92008-04-09 18:18:43 +0000219- zlib.decompressobj().flush(value) no longer crashes the interpreter when
220 passed a value less than or equal to zero.
221
Brett Cannone9746892008-04-12 23:44:07 +0000222- Issue #1631171: Re-implement the 'warnings' module in C (the original Python
223 code has been kept as backup). This will allow for using the 'warning's
224 machinery in such places as the parser where use of pure Python code is not
Brett Cannonb457dda2008-05-02 02:25:09 +0000225 possible. Both the ``showarning()`` and ``formatwarning()`` gain an
226 optional 'line' argument which is not called by default for
Brett Cannon8a232cc2008-05-05 05:32:07 +0000227 backwards-compatibility reasons. Setting ``warnings.showwarning()`` to
228 an implementation that lacks support for the ``line`` argument will raise a
229 DeprecationWarning.

255 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +0000256

276 file.close() is called while an object is in use by another thread
277 an IOError exception will be raised and the file will not be closed.
278
Thomas Hellerf7906482008-04-04 19:43:25 +0000279- The bundled libffi copy is now in sync with the recently released

286
Barry Warsawba437742008-04-04 01:34:41 +0000287Tests
288-----
Trent Nelsone41b0062008-04-08 23:47:30 +0000289- Issue #2550: The approach used by client/server code for obtaining ports
290 to listen on in network-oriented tests has been refined in an effort to
291 facilitate running multiple instances of the entire regression test suite
292 in parallel without issue. test_support.bind_port() has been fixed such
293 that it will always return a unique port -- which wasn't always the case
294 with the previous implementation, especially if socket options had been
295 set that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
296 new implementation of bind_port() will actually raise an exception if it
297 is passed an AF_INET/SOCK_STREAM socket with either the SO_REUSEADDR or
298 SO_REUSEPORT socket option set. Furthermore, if available, bind_port()
299 will set the SO_EXCLUSIVEADDRUSE option on the socket it's been passed.
300 This currently only applies to Windows. This option prevents any other
301 sockets from binding to the host/port we've bound to, thus removing the
302 possibility of the 'non-deterministic' behaviour, as Microsoft puts it,
303 that occurs when a second SOCK_STREAM socket binds and accepts to a
304 host/port that's already been bound by another socket. The optional
305 preferred port parameter to bind_port() has been removed. Under no
306 circumstances should tests be hard coding ports!
307
308 test_support.find_unused_port() has also been introduced, which will pass
309 a temporary socket object to bind_port() in order to obtain an unused port.
310 The temporary socket object is then closed and deleted, and the port is
311 returned. This method should only be used for obtaining an unused port
312 in order to pass to an external program (i.e. the -accept [port] argument
313 to openssl's s_server mode) or as a parameter to a server-oriented class
314 that doesn't give you direct access to the underlying socket used.
315
316 Finally, test_support.HOST has been introduced, which should be used for
317 the host argument of any relevant socket calls (i.e. bind and connect).
318
319 The following tests were updated to following the new conventions:
320 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
321 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
322 test_asynchat and test_socket_ssl.
323
324 It is now possible for multiple instances of the regression test suite to
325 run in parallel without issue.

593
Eric Smitha73fbe72008-02-23 03:09:44 +0000594- Added the future_builtins module, which contains hex() and oct().
595 These are the PEP 3127 version of these functions, designed to be
596 compatible with the hex() and oct() builtins from Python 3.0. They
597 differ slightly in their output formats from the existing, unchanged
598 Python 2.6 builtins. The expected usage of the future_builtins
599 module is:
600 from future_builtins import hex, oct
601
Eric Smith7ef40bf2008-02-20 23:34:22 +0000602- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
603 exponents for exponents with absolute value < 100. Follows C99
604 standard. This is a change on Windows, which would use 3 digits.
605 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
606 so that any alterations it does to the resulting string will be
607 available in stringlib/formatter.h (for float.__format__).
608
Eric Smith5a3c1352008-02-19 13:21:56 +0000609- Implemented PEP 3101, Advanced String Formatting. This adds a new
610 builtin format(); a format() method for str and unicode; a
611 __format__() method to object, str, unicode, int, long, float, and
612 datetime; the class string.Formatter; and the C API
613 PyObject_Format().
614
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +0000615- Fixed several potential crashes, all caused by specially crafted __del__
616 methods exploiting objects in temporarily inconsistent state.
617
Vinay Sajipb7edfc42008-04-02 21:10:23 +0000618- Issue #2115: Important speedup in setting __slot__ attributes. Also
619 prevent a possible crash: an Abstract Base Class would try to access a slot
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +0000620 on a registered virtual subclass.
621
Christian Heimes2f0da532008-02-15 06:57:08 +0000622- Fixed repr() and str() of complex numbers with infinity or nan as real or
623 imaginary part.
624
Andrew M. Kuchlingc6511a82008-03-04 01:48:26 +0000625- Clear all free lists during a gc.collect() of the highest generation in order
Christian Heimes3b718a72008-02-14 12:47:33 +0000626 to allow pymalloc to free more arenas. Python may give back memory to the
627 OS earlier.
628
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +0000629- Issue #2045: Fix an infinite recursion triggered when printing a subclass of
630 collections.defaultdict, if its default_factory is set to a bound method.
631
Christian Heimesf75dbef2008-02-08 00:11:31 +0000632- Fixed a minor memory leak in dictobject.c. The content of the free
633 list was not freed on interpreter shutdown.
634
Christian Heimes6075a822008-02-06 12:44:34 +0000635- Limit free list of method and builtin function objects to 256 entries
636 each.
637
Amaury Forgeot d'Arc578a8ca2008-02-04 20:53:14 +0000638- Patch #1953: Added ``sys._compact_freelists()`` and the C API functions
639 ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +0000640 to compact the internal free lists of pre-allocted ints and floats.
641
Christian Heimes951cc0f2008-01-31 23:08:23 +0000642- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
643 Python expected the return type int but the fork familie returns pi_t.
644
Mark Dickinson105be772008-01-31 22:17:37 +0000645- Issue #1678380: Fix a bug that identifies 0j and -0j when they appear
646 in the same code unit.
647
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +0000648- Issue #2025 : Add tuple.count() and tuple.index() methods to comply with
649 the collections.Sequence API.
650
Christian Heimes4d4f2702008-01-30 11:32:37 +0000651- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and linebreak
652 detection
653
Christian Heimes422051a2008-02-04 18:00:12 +0000654- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear the
Christian Heimes908caac2008-01-27 23:34:59 +0000655 internal lookup cache for ref leak tests.
656
Georg Brandl0cdf9a32008-01-26 14:14:20 +0000657- Patch #1473257: generator objects gain a gi_code attribute. This is the
658 same object as the func_code attribute of the function that produced the
659 generator.
660
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +0000661- Issue #1920: "while 0" statements were completely removed by the compiler,
Vinay Sajipb7edfc42008-04-02 21:10:23 +0000662 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +0000663 the condition is false. Now the compiler correctly emits bytecode for the
664 "else" suite.
665
Guido van Rossumeead05f2008-01-24 18:21:02 +0000666- A few crashers fixed: weakref_in_del.py (issue #1377858);
667 loosing_dict_ref.py (issue #1303614, test67.py);
668 borrowed_ref_[34].py (not in tracker).
669
Vinay Sajipd7cf32e2008-01-24 12:43:33 +0000670- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +0000671 suppressed while an extension is loaded by calling SetErrorMode in
672 dynload_win.c. The error is still reported properly.
673
Christian Heimes082c9b02008-01-23 14:20:50 +0000674- Bug #1915: Python compiles with --enable-unicode=no again. However
675 several extension methods and modules do not work without unicode
676 support.
677
Georg Brandl26543b12008-01-21 18:36:51 +0000678- Issue #1882: when compiling code from a string, encoding cookies in the
679 second line of code were not always recognized correctly.
680
Georg Brandl14404b62008-01-19 19:27:05 +0000681- Issue #1679: "0x" was taken as a valid integer literal.
682
Georg Brandl6caad7d2008-01-26 14:19:22 +0000683- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +0000684 added.
685
Christian Heimesc94e2b52008-01-14 04:13:37 +0000686- sys.float_info / PyFloat_GetInfo: The floating point information
687 object was converted from a dict to a specialized structseq object.
688
Christian Heimesf31b69f2008-01-14 03:42:48 +0000689- Patch #1816: Added sys.flags structseq. It exposes the status of most
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000690 command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +0000691
Georg Brandl6caad7d2008-01-26 14:19:22 +0000692- Objects/structseq.c: Implemented new structseq representation. The patch
Christian Heimesf31b69f2008-01-14 03:42:48 +0000693 makes structseqs (e.g. the return value of os.stat) more readable.
Christian Heimes9c201962008-01-14 03:33:52 +0000694
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +0000695- Patch #1700288: added a type attribute cache that caches method accesses,
696 resulting in speedups in heavily object-oriented code.
697
Neal Norwitz3fc15b82008-01-10 05:42:58 +0000698- Bug #1776: __import__() no longer accepts filenames on any platform.
699 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +0000700
Georg Brandlaed6c662008-01-07 17:25:53 +0000701- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
702
Georg Brandl2da0fce2008-01-07 17:09:35 +0000703- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE envvar
704 and sys.dont_write_bytecode attribute. All these can be set to forbid Python
705 to attempt to write compiled bytecode files.
706
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +0000707- Improve some exception messages when Windows fails to load an extension
708 module. Now we get for example '%1 is not a valid Win32 application' instead
709 of 'error code 193'.
710
Christian Heimes8267d1d2008-01-04 00:37:34 +0000711- Bug #1481296: Fixed long(float('nan'))!=0L.
712
Christian Heimeseebb79c2008-01-03 22:32:26 +0000713- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x, y)
714 functions.
Christian Heimese2ca4242008-01-03 20:23:15 +0000715
Christian Heimes0a8143f2007-12-18 23:22:54 +0000716- Issue #1635: Platform independent creation and representation of NaN
717 and INF. float("nan"), float("inf") and float("-inf") now work on every
718 platform with IEEE 754 semantics.
719
Raymond Hettingerfd7ed402007-12-18 21:24:09 +0000720- Compiler now generates simpler and faster code for dictionary literals.
721 The oparg for BUILD_MAP now indicates an estimated dictionary size.
722 There is a new opcode, STORE_MAP, for adding entries to the dictionary.
723
Christian Heimesdb3d6cb2007-12-16 21:39:43 +0000724- Issue #1638: %zd configure test fails on Linux
725
Christian Heimes90e10e72007-12-14 02:35:23 +0000726- Issue #1620: New property decorator syntax was modifying the decorator
727 in place instead of creating a new decorator object.
728
Skip Montanaro26015492007-12-08 15:33:24 +0000729- Issue #1538: Avoid copying string in split/rsplit if the split
730 char is not found.
731
Andrew M. Kuchling395fe442007-12-05 13:27:20 +0000732- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +0000733 SystemError.
734
Nick Coghlanef01d822007-12-03 12:55:17 +0000735- PEP 366: Allow explicit relative imports when executing modules
736 inside packages with the -m switch via a new module level
737 __package__ attribute.
738
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +0000739- Issue #1402: Fix a crash on exit, when another thread is still running, and
740 if the deallocation of its frames somehow calls the PyGILState_Ensure() /
741 PyGILState_Release() functions.
742
Christian Heimes28104c52007-11-27 23:16:44 +0000743- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
744
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000745- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +0000746 attribute of an empty cell object.
747
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +0000748- Issue #1460: The utf-7 incremental decoder did not accept truncated input.
749 It now correctly saves its state between chunks of data.
750
Nick Coghlan327a39b2007-11-18 11:56:28 +0000751- Patch #1739468: Directories and zipfiles containing a __main__.py file can
752 now be directly executed by passing their name to the interpreter. The
753 directory/zipfile is automatically inserted as the first entry in sys.path.
754
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +0000755- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
756 generator expression when at the same time the executed code is closing a
757 paused generator.
758
Raymond Hettinger1760c8a2007-11-08 02:52:43 +0000759- sets and frozensets now have an isdisjoint() method.
760
Raymond Hettinger3f8caa32007-10-24 01:28:33 +0000761- optimize the performance of builtin.sum().
762
Neal Norwitz44f326e2007-10-05 05:29:17 +0000763- Fix warnings found by the new version of the Coverity checker.
764
Raymond Hettinger8f669372007-10-03 21:18:11 +0000765- The enumerate() builtin function is no longer bounded to sequences smaller
766 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
767 shifts from ints to longs.
768
Brett Cannon0b14f242007-09-30 19:45:10 +0000769- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
770 having a self-referential tuple, which is possible from C code. Nor did
771 object's tp_str consider that a type's tp_str could do something that could
772 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
773 respectively, fixed the issues.
774
Brett Cannon01531592007-09-17 03:28:34 +0000775- Issue #1164: It was possible to trigger deadlock when using the 'print'
776 statement to write to a file since the GIL was not released as needed. Now
777 PyObject_Print() does the right thing along with various tp_print
778 implementations of the built-in types and those in the collections module.
779
Brett Cannon4c20bc42007-09-11 21:02:28 +0000780- Issue #1147: Exceptions were directly allowing string exceptions in their
781 throw() method even though string exceptions no longer allowed.
782
Brett Cannona0c05512007-09-10 21:38:27 +0000783- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
784 list by using the recursion counter.
785
Brett Cannon1e534b52007-09-07 04:18:30 +0000786- Issue #1202533: Fix infinite recursion calls triggered by calls to
787 PyObject_Call() never calling back out to Python code to trigger recursion
788 depth updates/checks. Required the creation of a static RuntimeError
789 instance in case normalizing an exception put the recursion check value past
790 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
791
Martin v. Löwisa5136192007-09-04 14:19:28 +0000792- Patch #1031213: Decode source line in SyntaxErrors back to its original source
793 encoding.
794
Georg Brandl7c3b50d2007-07-12 08:38:00 +0000795- Patch #1673759: add a missing overflow check when formatting floats
796 with %G.
797
Neal Norwitzdb2b1b32007-06-11 07:36:24 +0000798- Prevent expandtabs() on string and unicode objects from causing a segfault
799 when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +0000800
Martin v. Löwisda587ab2007-06-08 17:29:20 +0000801- Bug #1733488: Fix compilation of bufferobject.c on AIX.
802
Georg Brandl25497a12007-06-01 19:20:27 +0000803- Bug #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +0000804
Neal Norwitz0ac60192007-05-27 04:08:54 +0000805- Add new attribute names for function objects. All the func_* become
806 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
807
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +0000808- Add -3 option to the interpreter to warn about features that are
809 deprecated and will be changed/removed in Python 3.0.
810
Georg Brandl2134e752007-05-21 20:34:16 +0000811- Patch #1686487: you can now pass any mapping after '**' in function
812 calls.
813
Collin Winter62903052007-05-18 23:11:24 +0000814- except clauses may now be spelled either "except E, target:" or
815 "except E as target:". This is to provide forwards compatibility with
816 Python 3.0.
817
Brett Cannon229cee22007-05-05 01:34:02 +0000818- Deprecate BaseException.message as per PEP 352.
819
Armin Rigo9790a272007-05-02 19:23:31 +0000820- Bug #1303614: don't expose object's __dict__ when the dict is
821 inherited from a builtin base.
822
Vinay Sajip8549ce32007-05-06 17:53:37 +0000823- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +0000824 setting a plain string, ie don't expand to single letter identifiers.
825
Raymond Hettinger13936692007-04-11 18:40:58 +0000826- Request #1191699: Slices can now be pickled.
827
Raymond Hettinger4db5fe92007-04-12 04:10:00 +0000828- Request #1193128: str.translate() now allows a None argument for
829 translations that only remove characters without re-mapping the
830 remaining characters.
831
Georg Brandl5cb76c12007-03-21 09:00:39 +0000832- Patch #1682205: a TypeError while unpacking an iterable is no longer
833 masked by a generic one with the message "unpack non-sequence".
834
Neal Norwitzaa754b72007-03-21 06:39:48 +0000835- Remove unused file Python/fmod.c.
836
Guido van Rossum143b5642007-03-23 04:58:42 +0000837- Bug #1683368: The object.__init__() and object.__new__() methods are
838 now stricter in rejecting excess arguments. The only time when
839 either allows excess arguments is when it is not overridden and the
840 other one is. For backwards compatibility, when both are
841 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +0000842 warning later). Also, type.__init__() insists on the same signature
843 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +0000844
Georg Brandl2b869942007-03-17 16:08:45 +0000845- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
846 to complex using its __complex__() method before falling back to the
847 __float__() method. Therefore, the functions in the cmath module now
848 can operate on objects that define a __complex__() method.
849
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +0000850- Patch #1623563: allow __class__ assignment for classes with __slots__.
851 The old and the new class are still required to have the same slot names.
852
Collin Winter77c67bd2007-03-16 04:11:30 +0000853- Patch #1642547: Fix an error/crash when encountering syntax errors in
854 complex if statements.
855
Žiga Seilnacht20f43d32007-03-15 11:44:55 +0000856- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
857 is called with an object that is faking its type.
858
Žiga Seilnacht71436f02007-03-14 12:24:09 +0000859- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
860 name.
861
Georg Brandl5240d742007-03-13 20:46:32 +0000862- Patch #1444529: the builtin compile() now accepts keyword arguments.
863
Georg Brandl7b9c5552007-03-12 14:30:05 +0000864- Bug #1678647: write a newline after printing an exception in any
865 case, even when converting the value to a string failed.
866
Georg Brandl871f1bc2007-03-12 13:17:36 +0000867- The dir() function has been extended to call the __dir__() method on
868 its argument, if it exists. If not, it will work like before. This allows
869 customizing the output of dir() in the presence of a __getattr__().
870
Collin Winter276887b2007-03-12 16:11:39 +0000871- Patch #922167: Python no longer segfaults when faced with infinitely
872 self-recursive reload() calls (as reported by bug #742342).
873
Žiga Seilnacht89032082007-03-11 15:54:54 +0000874- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
875
Collin Wintere38051d2007-03-09 20:33:07 +0000876- Patch #1491866: change the complex() constructor to allow parthensized
877 forms. This means complex(repr(x)) now works instead of raising a
878 ValueError.
879
Georg Brandlaa2321b2007-03-07 00:40:28 +0000880- Patch #703779: unset __file__ in __main__ after running a file. This
881 makes the filenames the warning module prints much more sensible when
882 a PYTHONSTARTUP file is used.
883
Georg Brandl49aafc92007-03-07 00:34:46 +0000884- Variant of patch #697613: don't exit the interpreter on a SystemExit
885 exception if the -i command line option or PYTHONINSPECT environment
886 variable is given, but break into the interactive interpreter just like
887 on other exceptions or normal program exit.
888
Georg Brandl00cd8182007-03-06 18:41:12 +0000889- Patch #1638879: don't accept strings with embedded NUL bytes in long().
890
Georg Brandl098cd692007-03-06 12:17:50 +0000891- Bug #1674503: close the file opened by execfile() in an error condition.
892
Georg Brandl0fca97a2007-03-05 22:28:08 +0000893- Patch #1674228: when assigning a slice (old-style), check for the

1768
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00001769- Issue829951: In the smtplib module, SMTP.starttls() now complies with
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00001770 RFC 3207 and forgets any knowledge obtained from the server not obtained
1771 from the TLS negotiation itself. Patch contributed by Bill Fenner.

1868 time so that opening a database previously created with the DB_DUP or
1869 DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
1870 Specifically: dictionary assignment to a DB object will replace all
1871 values for a given key when the database allows duplicate values.
1872 DB users should use DB.put(k, v) when they want to store duplicates; not
1873 DB[k] = v.
1874

2198
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00002199- ``PySet_Add()`` can now modify a newly created frozenset. Similarly to
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002200 ``PyTuple_SetItem``, it can be used to populate a brand new frozenset; but
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00002201 it does not steal a reference to the added item.
2202
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002203- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

2209- Patch #1720595: add T_BOOL to the range of structmember types.
2210
2211- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
2212 ``PyFloat_GetInfo()`` to the float API.
2213
2214- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
2215 format code incorrectly truncated the length to an int, even when
2216 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
2217 results with huge strings.
2218
2219- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE
2220 and Py_REFCNT.
2221
2222- PEP 3123: Provide forward compatibility with Python 3.0, while keeping
2223 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
2224 PyVarObject_HEAD_INIT.
2225
2226- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
2227
2228- Patch #1733960: Allow T_LONGLONG to accept ints.
2229
2230- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.

2235
2236- Fix some leftovers from the conversion from int to Py_ssize_t
2237 (relevant to strings and sequences of more than 2**31 items).
2238
2239- Make _PyGILState_NoteThreadState() static, it was not used anywhere
2240 outside of pystate.c and should not be necessary.
2241
Christian Heimes000a0742008-01-03 22:16:32 +00002242- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do absolute
2243 imports. In earlier versions they might have used relative imports under
2244 some conditions.
2245
Andrew M. Kuchlingadc60ab2008-01-04 02:26:00 +00002246- Added case insensitive comparison methods ``PyOS_stricmp(char*, char*)``
Christian Heimes000a0742008-01-03 22:16:32 +00002247 and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00002256- Patch #1706: Drop support for Win9x, WinME and NT4. Python now requires
Christian Heimes95d64472008-02-09 19:55:22 +00002257 Windows 2000 or greater. The _WINVER and NTDDI_VERSION macros are set to
2258 Win2k for x86/32bit builds and WinXP for AMD64 builds.

Brett Cannon5e263512007-05-20 23:17:38 +00002273- Removed the macfs module. It had been deprecated since Python 2.5. This
2274 lead to the deprecation of macostools.touched() as it relied solely on macfs
2275 and was a no-op under OS X.
