832
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000833- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
834 PyString_FromFormat or PyErr_Format to display size_t values. The macro
835 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
836 ``printf`` function, whereas PyString_FromFormat has an independent
837 implementation and uses "%zd" on all platforms for size_t values.
838 This makes a difference on win64, where ``printf`` needs "%Id" to display
839 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +0000859 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
860 mechanism. In the process, fix a bug where isinstance() and issubclass(),

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000999What's New in Python 2.6 beta 3?
1000================================
1001
Barry Warsaw07a4a382008-08-21 01:15:08 +00001002*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001003
1004Core and Builtins
1005-----------------
1006
Guido van Rossumf8402962008-08-20 15:01:50 +00001007- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1008 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1009 extensions do not automatically benefit from the class attribute
1010 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1011 to their tp_flags field if they care. This is a backwards
1012 compatibility feature; in 3.0, all types will use the cache by
1013 default.
1014
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001015- Keyword arguments can now follow starred arguments. (``f(a, *args,
1016 keyword=23)`` is now valid syntax.)
1017
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001018- ctypes function pointers that are COM methods have a boolean True
1019 value again.
1020
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001021- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1022 by denying s# to parse objects that have a releasebuffer procedure,
1023 and introducing s*.
1024
Georg Brandl1e13ea92008-08-11 09:07:59 +00001025- Issue #3537: Fix an assertion failure when an empty but presized dict
1026 object was stored in the freelist.
1027
Mark Dickinsonb6467572008-08-04 21:30:09 +00001028- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1029 ValueError consistently across platforms.
1030
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001031- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1032 (64bit Unix, for example), unichr() would truncate its argument and return
1033 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1034
Neal Norwitze7d8be82008-07-31 17:17:14 +00001035- Apply security patches from Apple.
1036
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001037- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1038 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1039
Antoine Pitrou92f82162008-07-25 22:22:08 +00001040- Issue #1819: function calls with several named parameters are now on
1041 average 35% faster (as measured by pybench).
1042
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001043- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1044 the python debugger steps into a class statement: the free variables (local
1045 variables defined in an outer scope) would be deleted from the outer scope.
1046
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001047- Issue #2620: Overflow checking when allocating or reallocating memory
1048 was not always being done properly in some python types and extension
1049 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1050 all been updated to perform better checks and places in the code that
1051 would previously leak memory on the error path when such an allocation
1052 failed have been fixed.
1053
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001054Library
1055-------
1056
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001057- Issue #3612: Added some missing basic types in ctypes.wintypes.
1058
Benjamin Petersone977ad42008-08-20 01:42:01 +00001059- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1060 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1061
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001062- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1063 version reported by these tools does not necessarily follow the python
1064 version numbering scheme, so the module is less strict when parsing it.
1065
Nick Coghlanf70385a2008-08-18 12:42:46 +00001066- Issue #2235: Added Py3k warnings for types which will become unhashable
1067 under the stricter __hash__ inheritance rules in 3.0. Several types
1068 which did not meet the rules for hash invariants and were already
1069 unhashable in 3.0 have now been explicitly flagged as unhashable in
1070 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1071 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1072
Brett Cannon88f801d2008-08-18 00:46:22 +00001073- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1074 imported into the module but exposed as part of the module's API.
1075
Brett Cannon7b96f072008-08-18 00:41:11 +00001076- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1077
Brett Cannon46225e72008-08-18 00:36:52 +00001078- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1079
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001080- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1081
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001082- Issue #3575: Incremental decoder's decode function now takes bytearray
1083 by using 's*' instead of 't#'.
1084
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001085- Issue #2222: Fixed reference leak when occured os.rename()
1086 fails unicode conversion on 2nd parameter. (windows only)
1087
Facundo Batista94f243a2008-08-17 03:38:39 +00001088- Issue 2464. urllib2 now supports a malformation in the URL received
1089 in a redirect.
1090
Brett Cannonabe423e2008-08-16 21:47:07 +00001091- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001092 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001093
Facundo Batistaeb90b782008-08-16 14:44:07 +00001094- Issue #2776: fixed small issue when handling an URL with double slash
1095 after a 302 response in the case of not going through a proxy.
1096
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001097- Issue #2676: in the email package, content-type parsing was hanging on
1098 pathological input because of quadratic or exponential behaviour of a
1099 regular expression.
1100
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001101- Issue #3476: binary buffered reading through the new "io" library is now
1102 thread-safe.
1103
Brett Cannonbf3157b2008-08-14 05:00:03 +00001104- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1105 since mimetools itself is deprecated. Because modules are cached, all
1106 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1107
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001108- Issue #3134: shutil referenced undefined WindowsError symbol.
1109
Robert Schuppenies14646332008-08-10 11:01:53 +00001110- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1111 menu entries were not deleted.
1112
Brett Cannon83e81842008-08-09 23:30:55 +00001113- Copied the implementation of reduce() to _functools.reduce() to have a
1114 version that did not raise a DeprecationWarning under -3.
1115
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001116- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1117 a MemoryError rather than silently stop the iteration.
1118
Guido van Rossum59ce9012008-08-09 14:55:34 +00001119- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1120 to _sre.compile() will now be rejected. This should not affect anybody
1121 since the re.compile() function never generates invalid re-bytecode.
1122
Skip Montanaroa032bf42008-08-08 22:52:51 +00001123- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1124 upon first access it can be automatically initialized from the csv file if
1125 it wasn't initialized during instantiation.
1126
Brett Cannon3aa2a492008-08-06 22:28:09 +00001127- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1128 the reload() built-in has been removed.
1129
Brett Cannon7e30b672008-08-04 21:52:25 +00001130- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001131 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1135 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1136 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001137

1139 raised an AttributeError.
1140
Benjamin Peterson01a24322008-07-28 23:35:27 +00001141- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001142 asking for a specific length. This problem only affected files opened
1143 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001144
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001145- Issue #3449: Update decimal module to use most recent specification
1146 (v. 1.68) and tests (v. 2.58) from IBM.
1147
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001148- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

1156
1157- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1158 invalid arguments.
1159
1160- Issue #3302: Fix several crashes when calling locale's gettext functions
1161 with None arguments.
1162
1163- Issue #3389: Allow resolving dotted names for handlers in logging
1164 configuration files.
1165
1166- Deprecate the sunaudio module for removal in Python 3.0.
1167
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001168- Issue #3394: zipfile.writestr sets external attributes when passed a
1169 file name rather than a ZipInfo instance, so files are extracted with
1170 mode 0600 rather than 000 under Unix.
1171
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001172- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1173 argument in python 2.5, this broke code that subclassed Popen to include its
1174 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1183
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001184- Issue #2235: the C API function PyObject_HashNotImplemented and its
1185 interaction with the tp_hash slot (added in 2.6b2) are now documented
1186
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001187- Issue #643841: The language reference now provides more detailed
1188 coverage of the lookup process for special methods. The disclaimers
1189 regarding lack of coverage of new-style classes have also been
1190 removed, since the coverage is now fairly reasonable.

1194================================
1195
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001196*Release date: 17-Jul-2008*

1199-----------------
1200
Georg Brandl3e483f62008-07-16 22:57:41 +00001201- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1202 its methods now allow for items objects that can be converted to
1203 an integer using operator.index().
1204
Mark Dickinson64b7e502008-07-16 09:40:03 +00001205- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1206 produced a ValueError instead of giving the correct float.
1207
Eric Smitha5fa5a22008-07-16 00:11:49 +00001208- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1209 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1210
Mark Dickinson7103aa42008-07-15 19:08:33 +00001211- Issue #3008: the float type has a new instance method 'float.hex'
1212 and a new class method 'float.fromhex' to convert floating-point
1213 numbers to and from hexadecimal strings, respectively.
1214
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001215- Issue #2235: __hash__ is once again inherited by default. To allow
1216 collections.Hashable to remain meaningful in the presence of the
1217 default hash implementation (object.__hash__), it is now possible
1218 to explicit block inheritance of hash by setting __hash__=None at
1219 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1220 level.
1221
Nick Coghlanb028f502008-07-13 14:52:36 +00001222- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1223 the parent module cannot be found while performing an absolute import.
1224 This means that an incorrectly defined __package__ attribute will
1225 now only prevent relative imports in that module rather than causing
1226 all imports from that module to fail.
1227
Nick Coghlan14ff9942008-07-08 14:21:42 +00001228- Issue #2517: Allow unicode messages in Exceptions again by correctly
1229 bypassing the instance dictionary when looking up __unicode__ on
1230 new-style classes.
1231
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001232- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1233 set to a custom object whose write() method happens to install
1234 another file in sys.stdout.

1238 another thread's dictionary.
1239
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001240- Issue #3004: Minor change to slice.indices(): the start and stop
1241 arguments are now treated identically, making the behaviour easier
1242 to describe and understand. For example, slice(None, -10,
1243 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1244 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1245 10, -1).
1246
Georg Brandl278fc502008-07-19 12:46:12 +00001247- Issue #3219: Calling a function with repeated keyword arguments,
1248 f(a=2, a=23), would not cause a syntax error. This was a regression
1249 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00001699 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001700
1701 This is controlled by the configure argument ``--with-universal-archs``:
1702
1703 - ``--with-universal-archs=all``: install 4-way universal
1704
1705 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1706
1707 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1708

Georg Brandl3ee81df2008-05-17 18:14:43 +00001761- Issue #1631171: Re-implement the 'warnings' module in C (the
1762 original Python code has been kept as backup). This will allow for
1763 using the 'warning's machinery in such places as the parser where
1764 use of pure Python code is not possible. Both the ``showarning()``
1765 and ``formatwarning()`` gain an optional 'line' argument which is
1766 not called by default for backwards-compatibility reasons. Setting
1767 ``warnings.showwarning()`` to an implementation that lacks support
1768 for the ``line`` argument will raise a DeprecationWarning.

1792
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001793- The getpass module has been improved on Unix. It now uses /dev/tty
1794 by default and uses stderr instead of stdout. A GetPassWarning is
1795 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001810- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001811 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00001823- Issue #2385: distutils.core.run_script() makes __file__ available,
1824 so the controlled environment will more closely mirror the typical
1825 script environment. This supports setup.py scripts that refer to
1826 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001831- Issue #2550: The approach used by client/server code for obtaining
1832 ports to listen on in network-oriented tests has been refined in an
1833 effort to facilitate running multiple instances of the entire
1834 regression test suite in parallel without issue.
1835 test_support.bind_port() has been fixed such that it will always
1836 return a unique port -- which wasn't always the case with the
1837 previous implementation, especially if socket options had been set
1838 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1839 new implementation of bind_port() will actually raise an exception
1840 if it is passed an AF_INET/SOCK_STREAM socket with either the
1841 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1842 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1843 the socket it's been passed. This currently only applies to
1844 Windows. This option prevents any other sockets from binding to the
1845 host/port we've bound to, thus removing the possibility of the
1846 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1847 when a second SOCK_STREAM socket binds and accepts to a host/port
1848 that's already been bound by another socket. The optional preferred
1849 port parameter to bind_port() has been removed. Under no
1850 circumstances should tests be hard coding ports!
1851
1852 test_support.find_unused_port() has also been introduced, which will
1853 pass a temporary socket object to bind_port() in order to obtain an
1854 unused port. The temporary socket object is then closed and
1855 deleted, and the port is returned. This method should only be used
1856 for obtaining an unused port in order to pass to an external program
1857 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1858 a parameter to a server-oriented class that doesn't give you direct
1859 access to the underlying socket used.
1860
1861 Finally, test_support.HOST has been introduced, which should be used
1862 for the host argument of any relevant socket calls (i.e. bind and
1863 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001864
1865 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001866 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001867 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1868 test_asynchat and test_socket_ssl.
1869
Georg Brandl3ee81df2008-05-17 18:14:43 +00001870 It is now possible for multiple instances of the regression test
1871 suite to run in parallel without issue.

2137Core and builtins
2138-----------------
2139
Fred Drakea8ee94b2008-03-01 02:45:07 +00002140- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002141 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002142
Georg Brandlad61bc82008-02-23 15:11:18 +00002143- Issue #2067: file.__exit__() now calls subclasses' close() method.
2144
2145- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002146
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002147- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002148 issue 215555 for a discussion.
2149
Eric Smitha73fbe72008-02-23 03:09:44 +00002150- Added the future_builtins module, which contains hex() and oct().
2151 These are the PEP 3127 version of these functions, designed to be
2152 compatible with the hex() and oct() builtins from Python 3.0. They
2153 differ slightly in their output formats from the existing, unchanged
2154 Python 2.6 builtins. The expected usage of the future_builtins
2155 module is:
2156 from future_builtins import hex, oct
2157
Eric Smith7ef40bf2008-02-20 23:34:22 +00002158- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2159 exponents for exponents with absolute value < 100. Follows C99
2160 standard. This is a change on Windows, which would use 3 digits.
2161 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2162 so that any alterations it does to the resulting string will be
2163 available in stringlib/formatter.h (for float.__format__).
2164
Eric Smith5a3c1352008-02-19 13:21:56 +00002165- Implemented PEP 3101, Advanced String Formatting. This adds a new
2166 builtin format(); a format() method for str and unicode; a
2167 __format__() method to object, str, unicode, int, long, float, and
2168 datetime; the class string.Formatter; and the C API
2169 PyObject_Format().
2170
Georg Brandl3ee81df2008-05-17 18:14:43 +00002171- Fixed several potential crashes, all caused by specially crafted
2172 __del__ methods exploiting objects in temporarily inconsistent
2173 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002174
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002175- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002176 prevent a possible crash: an Abstract Base Class would try to access
2177 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002178
Georg Brandl3ee81df2008-05-17 18:14:43 +00002179- Fixed repr() and str() of complex numbers with infinity or nan as
2180 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002181
Georg Brandl3ee81df2008-05-17 18:14:43 +00002182- Clear all free lists during a gc.collect() of the highest generation
2183 in order to allow pymalloc to free more arenas. Python may give back
2184 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002185
Georg Brandl3ee81df2008-05-17 18:14:43 +00002186- Issue #2045: Fix an infinite recursion triggered when printing a
2187 subclass of collections.defaultdict, if its default_factory is set
2188 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002189
Christian Heimesf75dbef2008-02-08 00:11:31 +00002190- Fixed a minor memory leak in dictobject.c. The content of the free
2191 list was not freed on interpreter shutdown.
2192
Georg Brandl3ee81df2008-05-17 18:14:43 +00002193- Limit free list of method and builtin function objects to 256
2194 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002195
Georg Brandl3ee81df2008-05-17 18:14:43 +00002196- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2197 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002198 to compact the internal free lists of pre-allocted ints and floats.
2199
Georg Brandl3ee81df2008-05-17 18:14:43 +00002200- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2201 calls. Python expected the return type int but the fork familie
2202 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002203
Georg Brandl3ee81df2008-05-17 18:14:43 +00002204- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2205 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002206
Georg Brandl3ee81df2008-05-17 18:14:43 +00002207- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2208 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002209

2211 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002212
Georg Brandl3ee81df2008-05-17 18:14:43 +00002213- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2214 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002215
Georg Brandl3ee81df2008-05-17 18:14:43 +00002216- Patch #1473257: generator objects gain a gi_code attribute. This is
2217 the same object as the func_code attribute of the function that
2218 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002219
Georg Brandl3ee81df2008-05-17 18:14:43 +00002220- Issue #1920: "while 0" statements were completely removed by the
2221 compiler, even in the presence of an "else" clause, which is
2222 supposed to be run when the condition is false. Now the compiler
2223 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002224
Guido van Rossumeead05f2008-01-24 18:21:02 +00002225- A few crashers fixed: weakref_in_del.py (issue #1377858);
2226 loosing_dict_ref.py (issue #1303614, test67.py);
2227 borrowed_ref_[34].py (not in tracker).
2228
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002229- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002230 suppressed while an extension is loaded by calling SetErrorMode in
2231 dynload_win.c. The error is still reported properly.
2232
Georg Brandl3ee81df2008-05-17 18:14:43 +00002233- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002234 several extension methods and modules do not work without unicode
2235 support.
2236
Georg Brandl26543b12008-01-21 18:36:51 +00002237- Issue #1882: when compiling code from a string, encoding cookies in the
2238 second line of code were not always recognized correctly.
2239
Georg Brandl14404b62008-01-19 19:27:05 +00002240- Issue #1679: "0x" was taken as a valid integer literal.
2241
Georg Brandl6caad7d2008-01-26 14:19:22 +00002242- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002243 added.
2244
Christian Heimesc94e2b52008-01-14 04:13:37 +00002245- sys.float_info / PyFloat_GetInfo: The floating point information
2246 object was converted from a dict to a specialized structseq object.
2247
Georg Brandl3ee81df2008-05-17 18:14:43 +00002248- Patch #1816: Added sys.flags structseq. It exposes the status of
2249 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002250
Georg Brandl3ee81df2008-05-17 18:14:43 +00002251- Objects/structseq.c: Implemented new structseq representation. The
2252 patch makes structseqs (e.g. the return value of os.stat) more
2253 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002254
Georg Brandl3ee81df2008-05-17 18:14:43 +00002255- Patch #1700288: added a type attribute cache that caches method
2256 accesses, resulting in speedups in heavily object-oriented code.

2264 envvar and sys.dont_write_bytecode attribute. All these can be set
2265 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002266
Georg Brandl3ee81df2008-05-17 18:14:43 +00002267- Improve some exception messages when Windows fails to load an
2268 extension module. Now we get for example '%1 is not a valid Win32
2269 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002277 and INF. float("nan"), float("inf") and float("-inf") now work on
2278 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002279
Georg Brandl3ee81df2008-05-17 18:14:43 +00002280- Compiler now generates simpler and faster code for dictionary
2281 literals. The oparg for BUILD_MAP now indicates an estimated
2282 dictionary size. There is a new opcode, STORE_MAP, for adding
2283 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002331- Issue #1686386: Tuple's tp_repr did not take into account the
2332 possibility of having a self-referential tuple, which is possible
2333 from C code. Nor did object's tp_str consider that a type's tp_str
2334 could do something that could lead to an inifinite recursion.
2335 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2336 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002338- Issue #1164: It was possible to trigger deadlock when using the
2339 'print' statement to write to a file since the GIL was not released
2340 as needed. Now PyObject_Print() does the right thing along with
2341 various tp_print implementations of the built-in types and those in
2342 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002343
Georg Brandl3ee81df2008-05-17 18:14:43 +00002344- Issue #1147: Exceptions were directly allowing string exceptions in
2345 their throw() method even though string exceptions no longer
2346 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002347
Georg Brandl3ee81df2008-05-17 18:14:43 +00002348- Issue #1096: Prevent a segfault from getting the repr of a very
2349 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002350
Brett Cannon1e534b52007-09-07 04:18:30 +00002351- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002352 PyObject_Call() never calling back out to Python code to trigger
2353 recursion depth updates/checks. Required the creation of a static
2354 RuntimeError instance in case normalizing an exception put the
2355 recursion check value past its limit. Fixes crashers
2356 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002357

Neal Norwitz0ac60192007-05-27 04:08:54 +00002371- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002372 __*__ attributes. (Some already existed, e.g., __doc__ and
2373 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002374
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002375- Add -3 option to the interpreter to warn about features that are
2376 deprecated and will be changed/removed in Python 3.0.
2377
Georg Brandl2134e752007-05-21 20:34:16 +00002378- Patch #1686487: you can now pass any mapping after '**' in function
2379 calls.
2380
Collin Winter62903052007-05-18 23:11:24 +00002381- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002382 "except E as target:". This is to provide forwards compatibility
2383 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002384
Brett Cannon229cee22007-05-05 01:34:02 +00002385- Deprecate BaseException.message as per PEP 352.
2386
Georg Brandl3ee81df2008-05-17 18:14:43 +00002387- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002388 inherited from a builtin base.
2389
Vinay Sajip8549ce32007-05-06 17:53:37 +00002390- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002391 setting a plain string, ie don't expand to single letter identifiers.
2392
Raymond Hettinger13936692007-04-11 18:40:58 +00002393- Request #1191699: Slices can now be pickled.
2394
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002395- Request #1193128: str.translate() now allows a None argument for
2396 translations that only remove characters without re-mapping the
2397 remaining characters.
2398
Georg Brandl5cb76c12007-03-21 09:00:39 +00002399- Patch #1682205: a TypeError while unpacking an iterable is no longer
2400 masked by a generic one with the message "unpack non-sequence".
2401
Neal Norwitzaa754b72007-03-21 06:39:48 +00002402- Remove unused file Python/fmod.c.
2403
Guido van Rossum143b5642007-03-23 04:58:42 +00002404- Bug #1683368: The object.__init__() and object.__new__() methods are
2405 now stricter in rejecting excess arguments. The only time when
2406 either allows excess arguments is when it is not overridden and the
2407 other one is. For backwards compatibility, when both are
2408 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002409 warning later). Also, type.__init__() insists on the same signature
2410 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002411
Georg Brandl3ee81df2008-05-17 18:14:43 +00002412- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2413 object to complex using its __complex__() method before falling back
2414 to the __float__() method. Therefore, the functions in the cmath
2415 module now can operate on objects that define a __complex__()
2416 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002417
Georg Brandl3ee81df2008-05-17 18:14:43 +00002418- Patch #1623563: allow __class__ assignment for classes with
2419 __slots__. The old and the new class are still required to have the
2420 same slot names.

2427 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002428
Georg Brandl3ee81df2008-05-17 18:14:43 +00002429- Patch #1680015: Don't modify __slots__ tuple if it contains an

2433
Georg Brandl7b9c5552007-03-12 14:30:05 +00002434- Bug #1678647: write a newline after printing an exception in any
2435 case, even when converting the value to a string failed.
2436
Georg Brandl871f1bc2007-03-12 13:17:36 +00002437- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002438 its argument, if it exists. If not, it will work like before. This
2439 allows customizing the output of dir() in the presence of a
2440 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00002442- Patch #922167: Python no longer segfaults when faced with infinitely
2443 self-recursive reload() calls (as reported by bug #742342).
2444

2449 parthensized forms. This means complex(repr(x)) now works instead of
2450 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002451
Georg Brandlaa2321b2007-03-07 00:40:28 +00002452- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002453 makes the filenames the warning module prints much more sensible
2454 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002455

2457 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002458 variable is given, but break into the interactive interpreter just
2459 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002467- Patch #1674228: when assigning a slice (old-style), check for the
2468 sq_ass_slice instead of the sq_slice slot.
2469
Georg Brandl3ee81df2008-05-17 18:14:43 +00002470- When printing an unraisable error, don't print exceptions. before
2471 the name. This duplicates the behavior whening normally printing
2472 exceptions.

3101 exception.

3314 partial fix for Bug #1574584.
3315
Georg Brandl3ee81df2008-05-17 18:14:43 +00003316- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003382- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3383 with RFC 3207 and forgets any knowledge obtained from the server not
3384 obtained from the TLS negotiation itself. Patch contributed by Bill
3385 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003386
Georg Brandl3ee81df2008-05-17 18:14:43 +00003387- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003388 that the SMTP.starttls() caller no longer needs to call ehlo()
3389 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003390 does not claim to support starttls. Adds the
3391 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3472 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3473 silently miscode subclasses of those types. Now, it raises a
3474 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003475

Georg Brandl3ee81df2008-05-17 18:14:43 +00003490 time so that opening a database previously created with the DB_DUP
3491 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3492 opens. Specifically: dictionary assignment to a DB object will
3493 replace all values for a given key when the database allows
3494 duplicate values. DB users should use DB.put(k, v) when they want
3495 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003496

3502 characters with ASCII value less than 32. Also, it correctly quotes
3503 dots only if they occur on a single line, as opposed to the previous
3504 behavior of quoting dots if they are the second character of any
3505 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003506

3828-----
3829
Georg Brandl3ee81df2008-05-17 18:14:43 +00003830- Unified naming convention for free lists and their limits. All free
3831 lists in Object/ are named ``free_list``, the counter ``numfree``
3832 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
3833 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003834
Georg Brandl3ee81df2008-05-17 18:14:43 +00003835- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3836 to ``PyTuple_SetItem``, it can be used to populate a brand new
3837 frozenset; but it does not steal a reference to the added item.

3842 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
3843 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003844
3845- Patch #1720595: add T_BOOL to the range of structmember types.
3846
3847- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
3848 ``PyFloat_GetInfo()`` to the float API.
3849
Georg Brandl3ee81df2008-05-17 18:14:43 +00003850- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3851 of w# format code incorrectly truncated the length to an int, even
3852 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3853 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003854
Georg Brandl3ee81df2008-05-17 18:14:43 +00003855- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
3856 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003858- PEP 3123: Provide forward compatibility with Python 3.0, while
3859 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
3860 and PyVarObject_HEAD_INIT.

3872
3873- Fix some leftovers from the conversion from int to Py_ssize_t
3874 (relevant to strings and sequences of more than 2**31 items).
3875
3876- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3877 outside of pystate.c and should not be necessary.
3878
Georg Brandl3ee81df2008-05-17 18:14:43 +00003879- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3880 absolute imports. In earlier versions they might have used relative
3881 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003882
Georg Brandl3ee81df2008-05-17 18:14:43 +00003883- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3884 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003885
Georg Brandl3ee81df2008-05-17 18:14:43 +00003886- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00003893- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3894 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3895 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3896 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003897

Georg Brandl3ee81df2008-05-17 18:14:43 +00003911- Removed the macfs module. It had been deprecated since Python 2.5.
3912 This lead to the deprecation of macostools.touched() as it relied
3913 solely on macfs and was a no-op under OS X.
