Georg Brandld2094602008-12-05 08:51:30 +000079 method on file objects with closefd=False. The file descriptor is still

201
202- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
203 302 conformant loader) will now work correctly in most cases (they
204 are still subject to the constraints that exist for all code running
205 from inside a module loaded via a PEP 302 loader and attempting to

248
Benjamin Peterson866eba92008-11-19 22:05:53 +0000249- Issue #4348: Some bytearray methods returned that didn't cause any change to

251

535
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000536- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
537 PyString_FromFormat or PyErr_Format to display size_t values. The macro
538 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
539 ``printf`` function, whereas PyString_FromFormat has an independent
540 implementation and uses "%zd" on all platforms for size_t values.
541 This makes a difference on win64, where ``printf`` needs "%Id" to display

Antoine Pitrou0668c622008-08-26 22:42:08 +0000562 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
563 mechanism. In the process, fix a bug where isinstance() and issubclass(),

634 path to the Python binary.
635
Brett Cannon1eaf0742008-09-02 01:25:16 +0000636- Issue 3602: Moved test.test_support.catch_warning() to
637 warnings.catch_warnings() along with some API cleanup. Expanding the tests
638 for catch_warnings() also led to an improvement in the raising of a
639 DeprecationWarning related to warnings.warn_explicit().
640
Benjamin Peterson973e6c22008-09-01 23:12:58 +0000641- The deprecation warnings for the old camelCase threading API were removed.
642
Vinay Sajip35e3b032008-09-01 14:33:59 +0000643- logging: fixed lack of use of encoding attribute specified on a stream.
644

646
Christian Heimes1cc69632008-08-22 20:10:27 +0000647- Fixed two format strings in the _collections module.
648
Benjamin Peterson17f03ca2008-09-01 14:18:30 +0000649- Issue #3703: _fileio.FileIO gave unhelpful error message when trying to open a
650 directory.
Benjamin Petersonf22c26e2008-09-01 14:13:43 +0000651
Gregory P. Smithd7122032008-09-02 05:36:11 +0000652- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
653 non-integer floating point number.
654
Vinay Sajip65d66e12008-09-04 07:31:21 +0000655- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing
Jesse Nollerb814d6a2008-09-03 18:10:30 +0000656 SEM_VALUE_MAX.
657
Benjamin Peterson37346b22008-08-23 20:27:43 +0000658Extension Modules
659-----------------
660
Benjamin Peterson7fd60682009-03-13 20:48:10 +0000661- Issue #4301: Patch the logging module to add processName support, remove
662 _check_logger_class from multiprocessing.
663
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +0000664- Issue #2975: When compiling several extension modules with Visual Studio 2008
665 from the same python interpreter, some environment variables would grow
666 without limit.
667
Benjamin Peterson37346b22008-08-23 20:27:43 +0000668- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
669 exploitation of poor argument checking.
670
Gerhard Häringef2276b2008-09-12 13:54:06 +0000671- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
672
Gerhard Häring6e1afcf2008-09-12 18:58:57 +0000673- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
674 remaining ones have "pysqlite_" prefix.
675
Gerhard Häringe6872eb2008-09-12 22:33:22 +0000676- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves
677 concurrent access to the same SQLite database from multiple
678 threads/processes.

684 wrapper for warnings.catch_warnings() that makes it easier to check
685 that expected warning messages are being reported.
686
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +0000687- Issue #3796: Some tests functions were not enabled in test_float.
688
689- Issue #3768: Move test_py3kwarn over to the new API for catch_warnings().
Brett Cannona0b74442008-09-03 22:45:11 +0000690

695
Martin v. Löwis3f5fda82008-09-08 13:50:10 +0000696- Issue #2271: Set SecureCustomProperties so that installation will properly

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000705What's New in Python 2.6 beta 3?
706================================
707
Barry Warsaw07a4a382008-08-21 01:15:08 +0000708*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000709
710Core and Builtins
711-----------------
712
Guido van Rossumf8402962008-08-20 15:01:50 +0000713- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
714 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
715 extensions do not automatically benefit from the class attribute
716 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
717 to their tp_flags field if they care. This is a backwards
718 compatibility feature; in 3.0, all types will use the cache by
719 default.
720
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000721- Keyword arguments can now follow starred arguments. (``f(a, *args,
722 keyword=23)`` is now valid syntax.)
723
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000724- ctypes function pointers that are COM methods have a boolean True
725 value again.
726
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000727- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
728 by denying s# to parse objects that have a releasebuffer procedure,
729 and introducing s*.
730
Georg Brandl1e13ea92008-08-11 09:07:59 +0000731- Issue #3537: Fix an assertion failure when an empty but presized dict
732 object was stored in the freelist.
733
Mark Dickinsonb6467572008-08-04 21:30:09 +0000734- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
735 ValueError consistently across platforms.
736
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000737- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
738 (64bit Unix, for example), unichr() would truncate its argument and return
739 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
740
Neal Norwitze7d8be82008-07-31 17:17:14 +0000741- Apply security patches from Apple.
742
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000743- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
744 PyErr_ExceptionMatches returns 0 when an exception occurs there.
745
Antoine Pitrou92f82162008-07-25 22:22:08 +0000746- Issue #1819: function calls with several named parameters are now on
747 average 35% faster (as measured by pybench).
748
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000749- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
750 the python debugger steps into a class statement: the free variables (local
751 variables defined in an outer scope) would be deleted from the outer scope.
752
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000753- Issue #2620: Overflow checking when allocating or reallocating memory
754 was not always being done properly in some python types and extension
755 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
756 all been updated to perform better checks and places in the code that
757 would previously leak memory on the error path when such an allocation
758 failed have been fixed.
759
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000760Library
761-------
762

Benjamin Petersone977ad42008-08-20 01:42:01 +0000765- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
766 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
767
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000768- Issue #2234: distutils failed for some versions of the cygwin compiler. The
769 version reported by these tools does not necessarily follow the python
770 version numbering scheme, so the module is less strict when parsing it.
771
Nick Coghlanf70385a2008-08-18 12:42:46 +0000772- Issue #2235: Added Py3k warnings for types which will become unhashable
773 under the stricter __hash__ inheritance rules in 3.0. Several types
774 which did not meet the rules for hash invariants and were already
775 unhashable in 3.0 have now been explicitly flagged as unhashable in
776 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
777 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
778
Brett Cannon88f801d2008-08-18 00:46:22 +0000779- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

787
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000788- Issue #3575: Incremental decoder's decode function now takes bytearray
789 by using 's*' instead of 't#'.
790
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000791- Issue #2222: Fixed reference leak when occured os.rename()
792 fails unicode conversion on 2nd parameter. (windows only)
793
Facundo Batista94f243a2008-08-17 03:38:39 +0000794- Issue 2464. urllib2 now supports a malformation in the URL received
795 in a redirect.
796
Brett Cannonabe423e2008-08-16 21:47:07 +0000797- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +0000798 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +0000799
Facundo Batistaeb90b782008-08-16 14:44:07 +0000800- Issue #2776: fixed small issue when handling an URL with double slash
801 after a 302 response in the case of not going through a proxy.
802
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000803- Issue #2676: in the email package, content-type parsing was hanging on
804 pathological input because of quadratic or exponential behaviour of a
805 regular expression.
806
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000807- Issue #3476: binary buffered reading through the new "io" library is now
808 thread-safe.
809
Brett Cannonbf3157b2008-08-14 05:00:03 +0000810- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
811 since mimetools itself is deprecated. Because modules are cached, all
812 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
813
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000814- Issue #3134: shutil referenced undefined WindowsError symbol.
815
Robert Schuppenies14646332008-08-10 11:01:53 +0000816- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
817 menu entries were not deleted.
818
Brett Cannon83e81842008-08-09 23:30:55 +0000819- Copied the implementation of reduce() to _functools.reduce() to have a
820 version that did not raise a DeprecationWarning under -3.
821
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000822- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
823 a MemoryError rather than silently stop the iteration.
824
Guido van Rossum59ce9012008-08-09 14:55:34 +0000825- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
826 to _sre.compile() will now be rejected. This should not affect anybody
827 since the re.compile() function never generates invalid re-bytecode.
828
Skip Montanaroa032bf42008-08-08 22:52:51 +0000829- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
830 upon first access it can be automatically initialized from the csv file if
831 it wasn't initialized during instantiation.
832
Brett Cannon3aa2a492008-08-06 22:28:09 +0000833- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
834 the reload() built-in has been removed.

842 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +0000843

873
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +0000874- Issue #3394: zipfile.writestr sets external attributes when passed a
875 file name rather than a ZipInfo instance, so files are extracted with
876 mode 0600 rather than 000 under Unix.
877
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +0000878- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
879 argument in python 2.5, this broke code that subclassed Popen to include its

Raymond Hettingere3ae6552008-06-20 04:18:15 +0000899What's New in Python 2.6 beta 2?
900================================
901
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000902*Release date: 17-Jul-2008*
903
Raymond Hettingere3ae6552008-06-20 04:18:15 +0000904Core and Builtins
905-----------------
906
Georg Brandl3e483f62008-07-16 22:57:41 +0000907- Issue #3156: Fix inconsistent behavior of the bytearray type: all
908 its methods now allow for items objects that can be converted to
909 an integer using operator.index().
910
Mark Dickinson64b7e502008-07-16 09:40:03 +0000911- Issue #3360: Fix incorrect parsing of '020000000000.0', which
912 produced a ValueError instead of giving the correct float.
913
Eric Smitha5fa5a22008-07-16 00:11:49 +0000914- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
915 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
916
Mark Dickinson7103aa42008-07-15 19:08:33 +0000917- Issue #3008: the float type has a new instance method 'float.hex'
918 and a new class method 'float.fromhex' to convert floating-point
919 numbers to and from hexadecimal strings, respectively.
920
Nick Coghlan6d6bd442008-07-15 15:40:22 +0000921- Issue #2235: __hash__ is once again inherited by default. To allow
922 collections.Hashable to remain meaningful in the presence of the
923 default hash implementation (object.__hash__), it is now possible
924 to explicit block inheritance of hash by setting __hash__=None at
925 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
926 level.
927
Nick Coghlanb028f502008-07-13 14:52:36 +0000928- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
929 the parent module cannot be found while performing an absolute import.
930 This means that an incorrectly defined __package__ attribute will
931 now only prevent relative imports in that module rather than causing
932 all imports from that module to fail.
933
Nick Coghlan14ff9942008-07-08 14:21:42 +0000934- Issue #2517: Allow unicode messages in Exceptions again by correctly
935 bypassing the instance dictionary when looking up __unicode__ on
936 new-style classes.

Georg Brandl5cc774e2008-06-11 20:28:06 +00001405 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001406
1407 This is controlled by the configure argument ``--with-universal-archs``:

1454 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001467- Issue #1631171: Re-implement the 'warnings' module in C (the
1468 original Python code has been kept as backup). This will allow for
1469 using the 'warning's machinery in such places as the parser where
1470 use of pure Python code is not possible. Both the ``showarning()``
1471 and ``formatwarning()`` gain an optional 'line' argument which is
1472 not called by default for backwards-compatibility reasons. Setting
1473 ``warnings.showwarning()`` to an implementation that lacks support
1474 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001537- Issue #2550: The approach used by client/server code for obtaining
1538 ports to listen on in network-oriented tests has been refined in an
1539 effort to facilitate running multiple instances of the entire
1540 regression test suite in parallel without issue.
1541 test_support.bind_port() has been fixed such that it will always
1542 return a unique port -- which wasn't always the case with the
1543 previous implementation, especially if socket options had been set
1544 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1545 new implementation of bind_port() will actually raise an exception
1546 if it is passed an AF_INET/SOCK_STREAM socket with either the
1547 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1548 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1549 the socket it's been passed. This currently only applies to
1550 Windows. This option prevents any other sockets from binding to the
1551 host/port we've bound to, thus removing the possibility of the
1552 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1553 when a second SOCK_STREAM socket binds and accepts to a host/port
1554 that's already been bound by another socket. The optional preferred
1555 port parameter to bind_port() has been removed. Under no
1556 circumstances should tests be hard coding ports!
1557
1558 test_support.find_unused_port() has also been introduced, which will
1559 pass a temporary socket object to bind_port() in order to obtain an
1560 unused port. The temporary socket object is then closed and
1561 deleted, and the port is returned. This method should only be used
1562 for obtaining an unused port in order to pass to an external program
1563 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1564 a parameter to a server-oriented class that doesn't give you direct
1565 access to the underlying socket used.
1566
1567 Finally, test_support.HOST has been introduced, which should be used
1568 for the host argument of any relevant socket calls (i.e. bind and
1569 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001570
1571 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001572 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001573 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1574 test_asynchat and test_socket_ssl.
1575
Georg Brandl3ee81df2008-05-17 18:14:43 +00001576 It is now possible for multiple instances of the regression test
1577 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001761 optional: it defaults to the traceback of the exception that is
1762 currently being handled (is mandatory to be in the middle of an
1763 exception, otherwise it raises ValueError).

1780
Thomas Heller78b8f442008-03-05 14:53:39 +00001781- The bundled libffi copy is now in sync with the recently released
1782 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00001783 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
1784 files are used. On all linux systems the --with-system-ffi
1785 configure option defaults to "yes".

1844-----------------
1845
Fred Drakea8ee94b2008-03-01 02:45:07 +00001846- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001847 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00001848
Georg Brandlad61bc82008-02-23 15:11:18 +00001849- Issue #2067: file.__exit__() now calls subclasses' close() method.
1850
1851- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00001852
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001853- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001854 issue 215555 for a discussion.
1855
Eric Smitha73fbe72008-02-23 03:09:44 +00001856- Added the future_builtins module, which contains hex() and oct().
1857 These are the PEP 3127 version of these functions, designed to be
1858 compatible with the hex() and oct() builtins from Python 3.0. They
1859 differ slightly in their output formats from the existing, unchanged
1860 Python 2.6 builtins. The expected usage of the future_builtins
1861 module is:
1862 from future_builtins import hex, oct
1863
Eric Smith7ef40bf2008-02-20 23:34:22 +00001864- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1865 exponents for exponents with absolute value < 100. Follows C99
1866 standard. This is a change on Windows, which would use 3 digits.
1867 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1868 so that any alterations it does to the resulting string will be
1869 available in stringlib/formatter.h (for float.__format__).
1870
Eric Smith5a3c1352008-02-19 13:21:56 +00001871- Implemented PEP 3101, Advanced String Formatting. This adds a new
1872 builtin format(); a format() method for str and unicode; a
1873 __format__() method to object, str, unicode, int, long, float, and
1874 datetime; the class string.Formatter; and the C API
1875 PyObject_Format().
1876
Georg Brandl3ee81df2008-05-17 18:14:43 +00001877- Fixed several potential crashes, all caused by specially crafted
1878 __del__ methods exploiting objects in temporarily inconsistent
1879 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001880
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001881- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001882 prevent a possible crash: an Abstract Base Class would try to access
1883 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00001884
Georg Brandl3ee81df2008-05-17 18:14:43 +00001885- Fixed repr() and str() of complex numbers with infinity or nan as
1886 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00001887
Georg Brandl3ee81df2008-05-17 18:14:43 +00001888- Clear all free lists during a gc.collect() of the highest generation
1889 in order to allow pymalloc to free more arenas. Python may give back
1890 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00001891
Georg Brandl3ee81df2008-05-17 18:14:43 +00001892- Issue #2045: Fix an infinite recursion triggered when printing a
1893 subclass of collections.defaultdict, if its default_factory is set
1894 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00001895
Christian Heimesf75dbef2008-02-08 00:11:31 +00001896- Fixed a minor memory leak in dictobject.c. The content of the free
1897 list was not freed on interpreter shutdown.
1898
Georg Brandl3ee81df2008-05-17 18:14:43 +00001899- Limit free list of method and builtin function objects to 256
1900 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00001901
Georg Brandl3ee81df2008-05-17 18:14:43 +00001902- Patch #1953: Added ``sys._compact_freelists()`` and the C API
1903 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00001904 to compact the internal free lists of pre-allocted ints and floats.
1905
Georg Brandl3ee81df2008-05-17 18:14:43 +00001906- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
1907 calls. Python expected the return type int but the fork familie
1908 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00001909
Georg Brandl3ee81df2008-05-17 18:14:43 +00001910- Issue #1678380: Fix a bug that identifies 0j and -0j when they
1911 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00001912
Georg Brandl3ee81df2008-05-17 18:14:43 +00001913- Issue #2025: Add tuple.count() and tuple.index() methods to comply
1914 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00001915

Georg Brandl3ee81df2008-05-17 18:14:43 +00001919- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
1920 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00001921
Georg Brandl3ee81df2008-05-17 18:14:43 +00001922- Patch #1473257: generator objects gain a gi_code attribute. This is
1923 the same object as the func_code attribute of the function that
1924 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00001925
Georg Brandl3ee81df2008-05-17 18:14:43 +00001926- Issue #1920: "while 0" statements were completely removed by the
1927 compiler, even in the presence of an "else" clause, which is
1928 supposed to be run when the condition is false. Now the compiler
1929 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00001930
Guido van Rossumeead05f2008-01-24 18:21:02 +00001931- A few crashers fixed: weakref_in_del.py (issue #1377858);
1932 loosing_dict_ref.py (issue #1303614, test67.py);
1933 borrowed_ref_[34].py (not in tracker).
1934
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00001935- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00001936 suppressed while an extension is loaded by calling SetErrorMode in
1937 dynload_win.c. The error is still reported properly.
1938
Georg Brandl3ee81df2008-05-17 18:14:43 +00001939- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00001940 several extension methods and modules do not work without unicode
1941 support.
1942
Georg Brandl26543b12008-01-21 18:36:51 +00001943- Issue #1882: when compiling code from a string, encoding cookies in the
1944 second line of code were not always recognized correctly.
1945
Georg Brandl14404b62008-01-19 19:27:05 +00001946- Issue #1679: "0x" was taken as a valid integer literal.
1947
Georg Brandl6caad7d2008-01-26 14:19:22 +00001948- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00001949 added.
1950
Christian Heimesc94e2b52008-01-14 04:13:37 +00001951- sys.float_info / PyFloat_GetInfo: The floating point information
1952 object was converted from a dict to a specialized structseq object.
1953
Georg Brandl3ee81df2008-05-17 18:14:43 +00001954- Patch #1816: Added sys.flags structseq. It exposes the status of
1955 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00001956
Georg Brandl3ee81df2008-05-17 18:14:43 +00001957- Objects/structseq.c: Implemented new structseq representation. The
1958 patch makes structseqs (e.g. the return value of os.stat) more
1959 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00001960
Georg Brandl3ee81df2008-05-17 18:14:43 +00001961- Patch #1700288: added a type attribute cache that caches method
1962 accesses, resulting in speedups in heavily object-oriented code.

1970 envvar and sys.dont_write_bytecode attribute. All these can be set
1971 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00001972
Georg Brandl3ee81df2008-05-17 18:14:43 +00001973- Improve some exception messages when Windows fails to load an
1974 extension module. Now we get for example '%1 is not a valid Win32
1975 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00001976

Christian Heimes0a8143f2007-12-18 23:22:54 +00001982- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00001983 and INF. float("nan"), float("inf") and float("-inf") now work on
1984 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00001985
Georg Brandl3ee81df2008-05-17 18:14:43 +00001986- Compiler now generates simpler and faster code for dictionary
1987 literals. The oparg for BUILD_MAP now indicates an estimated
1988 dictionary size. There is a new opcode, STORE_MAP, for adding
1989 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002018- Patch #1739468: Directories and zipfiles containing a __main__.py
2019 file can now be directly executed by passing their name to the
2020 interpreter. The directory/zipfile is automatically inserted as the
2021 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002023- Issue #1265: Fix a problem with sys.settrace, if the tracing
2024 function uses a generator expression when at the same time the
2025 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002026
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002027- sets and frozensets now have an isdisjoint() method.

2032
Georg Brandl3ee81df2008-05-17 18:14:43 +00002033- The enumerate() builtin function is no longer bounded to sequences
2034 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2035 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002036
Georg Brandl3ee81df2008-05-17 18:14:43 +00002037- Issue #1686386: Tuple's tp_repr did not take into account the
2038 possibility of having a self-referential tuple, which is possible
2039 from C code. Nor did object's tp_str consider that a type's tp_str
2040 could do something that could lead to an inifinite recursion.
2041 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2042 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002043
Georg Brandl3ee81df2008-05-17 18:14:43 +00002044- Issue #1164: It was possible to trigger deadlock when using the
2045 'print' statement to write to a file since the GIL was not released
2046 as needed. Now PyObject_Print() does the right thing along with
2047 various tp_print implementations of the built-in types and those in
2048 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002049
Georg Brandl3ee81df2008-05-17 18:14:43 +00002050- Issue #1147: Exceptions were directly allowing string exceptions in
2051 their throw() method even though string exceptions no longer
2052 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002053
Georg Brandl3ee81df2008-05-17 18:14:43 +00002054- Issue #1096: Prevent a segfault from getting the repr of a very
2055 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002056
Brett Cannon1e534b52007-09-07 04:18:30 +00002057- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002058 PyObject_Call() never calling back out to Python code to trigger
2059 recursion depth updates/checks. Required the creation of a static
2060 RuntimeError instance in case normalizing an exception put the
2061 recursion check value past its limit. Fixes crashers
2062 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002063

Neal Norwitz0ac60192007-05-27 04:08:54 +00002077- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002078 __*__ attributes. (Some already existed, e.g., __doc__ and
2079 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002080
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002081- Add -3 option to the interpreter to warn about features that are
2082 deprecated and will be changed/removed in Python 3.0.
2083
Georg Brandl2134e752007-05-21 20:34:16 +00002084- Patch #1686487: you can now pass any mapping after '**' in function
2085 calls.
2086
Collin Winter62903052007-05-18 23:11:24 +00002087- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002088 "except E as target:". This is to provide forwards compatibility
2089 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002090
Brett Cannon229cee22007-05-05 01:34:02 +00002091- Deprecate BaseException.message as per PEP 352.
2092
Georg Brandl3ee81df2008-05-17 18:14:43 +00002093- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002094 inherited from a builtin base.
2095
Vinay Sajip8549ce32007-05-06 17:53:37 +00002096- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002097 setting a plain string, ie don't expand to single letter identifiers.
2098
Raymond Hettinger13936692007-04-11 18:40:58 +00002099- Request #1191699: Slices can now be pickled.
2100
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002101- Request #1193128: str.translate() now allows a None argument for
2102 translations that only remove characters without re-mapping the
2103 remaining characters.
2104
Georg Brandl5cb76c12007-03-21 09:00:39 +00002105- Patch #1682205: a TypeError while unpacking an iterable is no longer
2106 masked by a generic one with the message "unpack non-sequence".
2107
Neal Norwitzaa754b72007-03-21 06:39:48 +00002108- Remove unused file Python/fmod.c.
2109
Guido van Rossum143b5642007-03-23 04:58:42 +00002110- Bug #1683368: The object.__init__() and object.__new__() methods are
2111 now stricter in rejecting excess arguments. The only time when
2112 either allows excess arguments is when it is not overridden and the
2113 other one is. For backwards compatibility, when both are
2114 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002115 warning later). Also, type.__init__() insists on the same signature
2116 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002117
Georg Brandl3ee81df2008-05-17 18:14:43 +00002118- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2119 object to complex using its __complex__() method before falling back
2120 to the __float__() method. Therefore, the functions in the cmath
2121 module now can operate on objects that define a __complex__()
2122 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002123
Georg Brandl3ee81df2008-05-17 18:14:43 +00002124- Patch #1623563: allow __class__ assignment for classes with
2125 __slots__. The old and the new class are still required to have the
2126 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002127
Georg Brandl3ee81df2008-05-17 18:14:43 +00002128- Patch #1642547: Fix an error/crash when encountering syntax errors

2132 ``object.__reduce_ex__()`` is called with an object that is faking
2133 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002134
Georg Brandl3ee81df2008-05-17 18:14:43 +00002135- Patch #1680015: Don't modify __slots__ tuple if it contains an

2139
Georg Brandl7b9c5552007-03-12 14:30:05 +00002140- Bug #1678647: write a newline after printing an exception in any
2141 case, even when converting the value to a string failed.
2142
Georg Brandl871f1bc2007-03-12 13:17:36 +00002143- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002144 its argument, if it exists. If not, it will work like before. This
2145 allows customizing the output of dir() in the presence of a
2146 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002147
Collin Winter276887b2007-03-12 16:11:39 +00002148- Patch #922167: Python no longer segfaults when faced with infinitely
2149 self-recursive reload() calls (as reported by bug #742342).
2150
Georg Brandl3ee81df2008-05-17 18:14:43 +00002151- Patch #1675981: remove unreachable code from ``type.__new__()``
2152 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002154- Patch #1491866: change the complex() constructor to allow
2155 parthensized forms. This means complex(repr(x)) now works instead of
2156 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002157
Georg Brandlaa2321b2007-03-07 00:40:28 +00002158- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002159 makes the filenames the warning module prints much more sensible
2160 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002161
Georg Brandl49aafc92007-03-07 00:34:46 +00002162- Variant of patch #697613: don't exit the interpreter on a SystemExit
2163 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002164 variable is given, but break into the interactive interpreter just
2165 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002170- Bug #1674503: close the file opened by execfile() in an error
2171 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00002172
Georg Brandl0fca97a2007-03-05 22:28:08 +00002173- Patch #1674228: when assigning a slice (old-style), check for the
2174 sq_ass_slice instead of the sq_slice slot.
2175
Georg Brandl3ee81df2008-05-17 18:14:43 +00002176- When printing an unraisable error, don't print exceptions. before
2177 the name. This duplicates the behavior whening normally printing
2178 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002179
Georg Brandl3ee81df2008-05-17 18:14:43 +00002180- Bug #1653736: Properly discard third argument to

2187 created a weakref on itself during a __del__ call for new-style
2188 classes (classic classes still have the bug).

2235
Armin Rigo7ccbca92006-10-04 12:17:45 +00002236- A number of places, including integer negation and absolute value,
2237 were fixed to not rely on undefined behaviour of the C compiler
2238 anymore.

Georg Brandl92a6bae2007-03-13 17:43:32 +00002745- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002746 are set for invalid interpolation sequences that would lead to

2803 TestCase and TestSuite subclasses (not instances) are no longer
2804 accepted in TestSuite.addTest(). This should cause no

2806 -- the failure just occurred later, with a more cumbersome
2807 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003088- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3089 with RFC 3207 and forgets any knowledge obtained from the server not
3090 obtained from the TLS negotiation itself. Patch contributed by Bill
3091 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003092
Georg Brandl3ee81df2008-05-17 18:14:43 +00003093- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003094 that the SMTP.starttls() caller no longer needs to call ehlo()
3095 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003096 does not claim to support starttls. Adds the
3097 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3178 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3179 silently miscode subclasses of those types. Now, it raises a
3180 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003181

Georg Brandl3ee81df2008-05-17 18:14:43 +00003196 time so that opening a database previously created with the DB_DUP
3197 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3198 opens. Specifically: dictionary assignment to a DB object will
3199 replace all values for a given key when the database allows
3200 duplicate values. DB users should use DB.put(k, v) when they want
3201 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003202

3208 characters with ASCII value less than 32. Also, it correctly quotes
3209 dots only if they occur on a single line, as opposed to the previous
3210 behavior of quoting dots if they are the second character of any
3211 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003212

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00003480- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00003481 periodic threadstate and signal checking in tight loops. By
3482 default, this option is turned-off. It should only be enabled in
3483 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00003540
Georg Brandl3ee81df2008-05-17 18:14:43 +00003541- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3542 to ``PyTuple_SetItem``, it can be used to populate a brand new

3555
Georg Brandl3ee81df2008-05-17 18:14:43 +00003556- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3557 of w# format code incorrectly truncated the length to an int, even
3558 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3559 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003560
Georg Brandl3ee81df2008-05-17 18:14:43 +00003561- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

3583 outside of pystate.c and should not be necessary.
3584
Georg Brandl3ee81df2008-05-17 18:14:43 +00003585- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do

Georg Brandl3ee81df2008-05-17 18:14:43 +00003589- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3590 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003591
Georg Brandl3ee81df2008-05-17 18:14:43 +00003592- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00003617- Removed the macfs module. It had been deprecated since Python 2.5.
3618 This lead to the deprecation of macostools.touched() as it relied
