473- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
474 302 conformant loader) will now work correctly in most cases (they
475 are still subject to the constraints that exist for all code running
476 from inside a module loaded via a PEP 302 loader and attempting to

829
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000830- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
831 PyString_FromFormat or PyErr_Format to display size_t values. The macro
832 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
833 ``printf`` function, whereas PyString_FromFormat has an independent
834 implementation and uses "%zd" on all platforms for size_t values.
835 This makes a difference on win64, where ``printf`` needs "%Id" to display
836 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +0000856 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
857 mechanism. In the process, fix a bug where isinstance() and issubclass(),

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000996What's New in Python 2.6 beta 3?
997================================
998
Barry Warsaw07a4a382008-08-21 01:15:08 +0000999*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001000
1001Core and Builtins
1002-----------------
1003
Guido van Rossumf8402962008-08-20 15:01:50 +00001004- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1005 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1006 extensions do not automatically benefit from the class attribute
1007 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1008 to their tp_flags field if they care. This is a backwards
1009 compatibility feature; in 3.0, all types will use the cache by
1010 default.
1011
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001012- Keyword arguments can now follow starred arguments. (``f(a, *args,
1013 keyword=23)`` is now valid syntax.)
1014
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001015- ctypes function pointers that are COM methods have a boolean True
1016 value again.
1017
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001018- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1019 by denying s# to parse objects that have a releasebuffer procedure,
1020 and introducing s*.
1021
Georg Brandl1e13ea92008-08-11 09:07:59 +00001022- Issue #3537: Fix an assertion failure when an empty but presized dict
1023 object was stored in the freelist.
1024
Mark Dickinsonb6467572008-08-04 21:30:09 +00001025- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1026 ValueError consistently across platforms.
1027
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001028- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1029 (64bit Unix, for example), unichr() would truncate its argument and return
1030 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1031
Neal Norwitze7d8be82008-07-31 17:17:14 +00001032- Apply security patches from Apple.
1033
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001034- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1035 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1036
Antoine Pitrou92f82162008-07-25 22:22:08 +00001037- Issue #1819: function calls with several named parameters are now on
1038 average 35% faster (as measured by pybench).
1039
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001040- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1041 the python debugger steps into a class statement: the free variables (local
1042 variables defined in an outer scope) would be deleted from the outer scope.
1043
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001044- Issue #2620: Overflow checking when allocating or reallocating memory
1045 was not always being done properly in some python types and extension
1046 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1047 all been updated to perform better checks and places in the code that
1048 would previously leak memory on the error path when such an allocation
1049 failed have been fixed.
1050
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001051Library
1052-------
1053
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001054- Issue #3612: Added some missing basic types in ctypes.wintypes.
1055
Benjamin Petersone977ad42008-08-20 01:42:01 +00001056- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1057 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1058
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001059- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1060 version reported by these tools does not necessarily follow the python
1061 version numbering scheme, so the module is less strict when parsing it.
1062
Nick Coghlanf70385a2008-08-18 12:42:46 +00001063- Issue #2235: Added Py3k warnings for types which will become unhashable
1064 under the stricter __hash__ inheritance rules in 3.0. Several types
1065 which did not meet the rules for hash invariants and were already
1066 unhashable in 3.0 have now been explicitly flagged as unhashable in
1067 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1068 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1069
Brett Cannon88f801d2008-08-18 00:46:22 +00001070- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1071 imported into the module but exposed as part of the module's API.
1072
Brett Cannon7b96f072008-08-18 00:41:11 +00001073- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1074
Brett Cannon46225e72008-08-18 00:36:52 +00001075- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1076
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001077- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1078
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001079- Issue #3575: Incremental decoder's decode function now takes bytearray
1080 by using 's*' instead of 't#'.
1081
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001082- Issue #2222: Fixed reference leak when occured os.rename()
1083 fails unicode conversion on 2nd parameter. (windows only)
1084
Facundo Batista94f243a2008-08-17 03:38:39 +00001085- Issue 2464. urllib2 now supports a malformation in the URL received
1086 in a redirect.
1087
Brett Cannonabe423e2008-08-16 21:47:07 +00001088- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001089 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001090
Facundo Batistaeb90b782008-08-16 14:44:07 +00001091- Issue #2776: fixed small issue when handling an URL with double slash
1092 after a 302 response in the case of not going through a proxy.
1093
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001094- Issue #2676: in the email package, content-type parsing was hanging on
1095 pathological input because of quadratic or exponential behaviour of a
1096 regular expression.
1097
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001098- Issue #3476: binary buffered reading through the new "io" library is now
1099 thread-safe.
1100
Brett Cannonbf3157b2008-08-14 05:00:03 +00001101- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1102 since mimetools itself is deprecated. Because modules are cached, all
1103 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1104
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001105- Issue #3134: shutil referenced undefined WindowsError symbol.
1106
Robert Schuppenies14646332008-08-10 11:01:53 +00001107- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1108 menu entries were not deleted.
1109
Brett Cannon83e81842008-08-09 23:30:55 +00001110- Copied the implementation of reduce() to _functools.reduce() to have a
1111 version that did not raise a DeprecationWarning under -3.
1112
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001113- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1114 a MemoryError rather than silently stop the iteration.
1115
Guido van Rossum59ce9012008-08-09 14:55:34 +00001116- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1117 to _sre.compile() will now be rejected. This should not affect anybody
1118 since the re.compile() function never generates invalid re-bytecode.
1119
Skip Montanaroa032bf42008-08-08 22:52:51 +00001120- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1121 upon first access it can be automatically initialized from the csv file if
1122 it wasn't initialized during instantiation.
1123
Brett Cannon3aa2a492008-08-06 22:28:09 +00001124- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1125 the reload() built-in has been removed.
1126
Brett Cannon7e30b672008-08-04 21:52:25 +00001127- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001128 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1132 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1133 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001134

1136 raised an AttributeError.
1137
Benjamin Peterson01a24322008-07-28 23:35:27 +00001138- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001139 asking for a specific length. This problem only affected files opened
1140 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001141
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001142- Issue #3449: Update decimal module to use most recent specification
1143 (v. 1.68) and tests (v. 2.58) from IBM.
1144
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001145- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

1153
1154- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1155 invalid arguments.
1156
1157- Issue #3302: Fix several crashes when calling locale's gettext functions
1158 with None arguments.
1159
1160- Issue #3389: Allow resolving dotted names for handlers in logging
1161 configuration files.
1162
1163- Deprecate the sunaudio module for removal in Python 3.0.
1164
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001165- Issue #3394: zipfile.writestr sets external attributes when passed a
1166 file name rather than a ZipInfo instance, so files are extracted with
1167 mode 0600 rather than 000 under Unix.
1168
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001169- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1170 argument in python 2.5, this broke code that subclassed Popen to include its
1171 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001181- Issue #2235: the C API function PyObject_HashNotImplemented and its
1182 interaction with the tp_hash slot (added in 2.6b2) are now documented
1183
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001184- Issue #643841: The language reference now provides more detailed
1185 coverage of the lookup process for special methods. The disclaimers
1186 regarding lack of coverage of new-style classes have also been
1187 removed, since the coverage is now fairly reasonable.

1191================================
1192
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001193*Release date: 17-Jul-2008*

1196-----------------
1197
Georg Brandl3e483f62008-07-16 22:57:41 +00001198- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1199 its methods now allow for items objects that can be converted to
1200 an integer using operator.index().
1201
Mark Dickinson64b7e502008-07-16 09:40:03 +00001202- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1203 produced a ValueError instead of giving the correct float.
1204
Eric Smitha5fa5a22008-07-16 00:11:49 +00001205- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1206 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1207
Mark Dickinson7103aa42008-07-15 19:08:33 +00001208- Issue #3008: the float type has a new instance method 'float.hex'
1209 and a new class method 'float.fromhex' to convert floating-point
1210 numbers to and from hexadecimal strings, respectively.
1211
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001212- Issue #2235: __hash__ is once again inherited by default. To allow
1213 collections.Hashable to remain meaningful in the presence of the
1214 default hash implementation (object.__hash__), it is now possible
1215 to explicit block inheritance of hash by setting __hash__=None at
1216 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1217 level.
1218
Nick Coghlanb028f502008-07-13 14:52:36 +00001219- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1220 the parent module cannot be found while performing an absolute import.
1221 This means that an incorrectly defined __package__ attribute will
1222 now only prevent relative imports in that module rather than causing
1223 all imports from that module to fail.
1224
Nick Coghlan14ff9942008-07-08 14:21:42 +00001225- Issue #2517: Allow unicode messages in Exceptions again by correctly
1226 bypassing the instance dictionary when looking up __unicode__ on
1227 new-style classes.
1228
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001229- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1230 set to a custom object whose write() method happens to install
1231 another file in sys.stdout.

1235 another thread's dictionary.
1236
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001237- Issue #3004: Minor change to slice.indices(): the start and stop
1238 arguments are now treated identically, making the behaviour easier
1239 to describe and understand. For example, slice(None, -10,
1240 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1241 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1242 10, -1).
1243
Georg Brandl278fc502008-07-19 12:46:12 +00001244- Issue #3219: Calling a function with repeated keyword arguments,
1245 f(a=2, a=23), would not cause a syntax error. This was a regression
1246 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00001696 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001697
1698 This is controlled by the configure argument ``--with-universal-archs``:
1699
1700 - ``--with-universal-archs=all``: install 4-way universal
1701
1702 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1703
1704 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1705

Georg Brandl3ee81df2008-05-17 18:14:43 +00001758- Issue #1631171: Re-implement the 'warnings' module in C (the
1759 original Python code has been kept as backup). This will allow for
1760 using the 'warning's machinery in such places as the parser where
1761 use of pure Python code is not possible. Both the ``showarning()``
1762 and ``formatwarning()`` gain an optional 'line' argument which is
1763 not called by default for backwards-compatibility reasons. Setting
1764 ``warnings.showwarning()`` to an implementation that lacks support
1765 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001820- Issue #2385: distutils.core.run_script() makes __file__ available,
1821 so the controlled environment will more closely mirror the typical
1822 script environment. This supports setup.py scripts that refer to
1823 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001828- Issue #2550: The approach used by client/server code for obtaining
1829 ports to listen on in network-oriented tests has been refined in an
1830 effort to facilitate running multiple instances of the entire
1831 regression test suite in parallel without issue.
1832 test_support.bind_port() has been fixed such that it will always
1833 return a unique port -- which wasn't always the case with the
1834 previous implementation, especially if socket options had been set
1835 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1836 new implementation of bind_port() will actually raise an exception
1837 if it is passed an AF_INET/SOCK_STREAM socket with either the
1838 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1839 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1840 the socket it's been passed. This currently only applies to
1841 Windows. This option prevents any other sockets from binding to the
1842 host/port we've bound to, thus removing the possibility of the
1843 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1844 when a second SOCK_STREAM socket binds and accepts to a host/port
1845 that's already been bound by another socket. The optional preferred
1846 port parameter to bind_port() has been removed. Under no
1847 circumstances should tests be hard coding ports!
1848
1849 test_support.find_unused_port() has also been introduced, which will
1850 pass a temporary socket object to bind_port() in order to obtain an
1851 unused port. The temporary socket object is then closed and
1852 deleted, and the port is returned. This method should only be used
1853 for obtaining an unused port in order to pass to an external program
1854 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1855 a parameter to a server-oriented class that doesn't give you direct
1856 access to the underlying socket used.
1857
1858 Finally, test_support.HOST has been introduced, which should be used
1859 for the host argument of any relevant socket calls (i.e. bind and
1860 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001861
1862 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001863 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001864 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1865 test_asynchat and test_socket_ssl.
1866
Georg Brandl3ee81df2008-05-17 18:14:43 +00001867 It is now possible for multiple instances of the regression test
1868 suite to run in parallel without issue.

2134Core and builtins
2135-----------------
2136
Fred Drakea8ee94b2008-03-01 02:45:07 +00002137- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002138 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002139
Georg Brandlad61bc82008-02-23 15:11:18 +00002140- Issue #2067: file.__exit__() now calls subclasses' close() method.
2141
2142- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002143
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002144- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002145 issue 215555 for a discussion.
2146
Eric Smitha73fbe72008-02-23 03:09:44 +00002147- Added the future_builtins module, which contains hex() and oct().
2148 These are the PEP 3127 version of these functions, designed to be
2149 compatible with the hex() and oct() builtins from Python 3.0. They
2150 differ slightly in their output formats from the existing, unchanged
2151 Python 2.6 builtins. The expected usage of the future_builtins
2152 module is:
2153 from future_builtins import hex, oct
2154
Eric Smith7ef40bf2008-02-20 23:34:22 +00002155- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2156 exponents for exponents with absolute value < 100. Follows C99
2157 standard. This is a change on Windows, which would use 3 digits.
2158 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2159 so that any alterations it does to the resulting string will be
2160 available in stringlib/formatter.h (for float.__format__).
2161
Eric Smith5a3c1352008-02-19 13:21:56 +00002162- Implemented PEP 3101, Advanced String Formatting. This adds a new
2163 builtin format(); a format() method for str and unicode; a
2164 __format__() method to object, str, unicode, int, long, float, and
2165 datetime; the class string.Formatter; and the C API
2166 PyObject_Format().
2167
Georg Brandl3ee81df2008-05-17 18:14:43 +00002168- Fixed several potential crashes, all caused by specially crafted
2169 __del__ methods exploiting objects in temporarily inconsistent
2170 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002171
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002172- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002173 prevent a possible crash: an Abstract Base Class would try to access
2174 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002175
Georg Brandl3ee81df2008-05-17 18:14:43 +00002176- Fixed repr() and str() of complex numbers with infinity or nan as
2177 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002178
Georg Brandl3ee81df2008-05-17 18:14:43 +00002179- Clear all free lists during a gc.collect() of the highest generation
2180 in order to allow pymalloc to free more arenas. Python may give back
2181 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002182
Georg Brandl3ee81df2008-05-17 18:14:43 +00002183- Issue #2045: Fix an infinite recursion triggered when printing a
2184 subclass of collections.defaultdict, if its default_factory is set
2185 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002186
Christian Heimesf75dbef2008-02-08 00:11:31 +00002187- Fixed a minor memory leak in dictobject.c. The content of the free
2188 list was not freed on interpreter shutdown.
2189
Georg Brandl3ee81df2008-05-17 18:14:43 +00002190- Limit free list of method and builtin function objects to 256
2191 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002192
Georg Brandl3ee81df2008-05-17 18:14:43 +00002193- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2194 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002195 to compact the internal free lists of pre-allocted ints and floats.
2196
Georg Brandl3ee81df2008-05-17 18:14:43 +00002197- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2198 calls. Python expected the return type int but the fork familie
2199 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002200
Georg Brandl3ee81df2008-05-17 18:14:43 +00002201- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2202 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002203
Georg Brandl3ee81df2008-05-17 18:14:43 +00002204- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2205 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002206

2208 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002209
Georg Brandl3ee81df2008-05-17 18:14:43 +00002210- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2211 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002212
Georg Brandl3ee81df2008-05-17 18:14:43 +00002213- Patch #1473257: generator objects gain a gi_code attribute. This is
2214 the same object as the func_code attribute of the function that
2215 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002216
Georg Brandl3ee81df2008-05-17 18:14:43 +00002217- Issue #1920: "while 0" statements were completely removed by the
2218 compiler, even in the presence of an "else" clause, which is
2219 supposed to be run when the condition is false. Now the compiler
2220 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002221
Guido van Rossumeead05f2008-01-24 18:21:02 +00002222- A few crashers fixed: weakref_in_del.py (issue #1377858);
2223 loosing_dict_ref.py (issue #1303614, test67.py);
2224 borrowed_ref_[34].py (not in tracker).
2225
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002226- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002227 suppressed while an extension is loaded by calling SetErrorMode in
2228 dynload_win.c. The error is still reported properly.
2229
Georg Brandl3ee81df2008-05-17 18:14:43 +00002230- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002231 several extension methods and modules do not work without unicode
2232 support.
2233
Georg Brandl26543b12008-01-21 18:36:51 +00002234- Issue #1882: when compiling code from a string, encoding cookies in the
2235 second line of code were not always recognized correctly.
2236
Georg Brandl14404b62008-01-19 19:27:05 +00002237- Issue #1679: "0x" was taken as a valid integer literal.
2238
Georg Brandl6caad7d2008-01-26 14:19:22 +00002239- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002240 added.
2241
Christian Heimesc94e2b52008-01-14 04:13:37 +00002242- sys.float_info / PyFloat_GetInfo: The floating point information
2243 object was converted from a dict to a specialized structseq object.
2244
Georg Brandl3ee81df2008-05-17 18:14:43 +00002245- Patch #1816: Added sys.flags structseq. It exposes the status of
2246 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002247
Georg Brandl3ee81df2008-05-17 18:14:43 +00002248- Objects/structseq.c: Implemented new structseq representation. The
2249 patch makes structseqs (e.g. the return value of os.stat) more
2250 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002251
Georg Brandl3ee81df2008-05-17 18:14:43 +00002252- Patch #1700288: added a type attribute cache that caches method
2253 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002254

2261 envvar and sys.dont_write_bytecode attribute. All these can be set
2262 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002263
Georg Brandl3ee81df2008-05-17 18:14:43 +00002264- Improve some exception messages when Windows fails to load an
2265 extension module. Now we get for example '%1 is not a valid Win32
2266 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00002273- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002274 and INF. float("nan"), float("inf") and float("-inf") now work on
2275 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002276
Georg Brandl3ee81df2008-05-17 18:14:43 +00002277- Compiler now generates simpler and faster code for dictionary
2278 literals. The oparg for BUILD_MAP now indicates an estimated
2279 dictionary size. There is a new opcode, STORE_MAP, for adding
2280 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002328- Issue #1686386: Tuple's tp_repr did not take into account the
2329 possibility of having a self-referential tuple, which is possible
2330 from C code. Nor did object's tp_str consider that a type's tp_str
2331 could do something that could lead to an inifinite recursion.
2332 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2333 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002335- Issue #1164: It was possible to trigger deadlock when using the
2336 'print' statement to write to a file since the GIL was not released
2337 as needed. Now PyObject_Print() does the right thing along with
2338 various tp_print implementations of the built-in types and those in
2339 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002341- Issue #1147: Exceptions were directly allowing string exceptions in
2342 their throw() method even though string exceptions no longer
2343 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002344
Georg Brandl3ee81df2008-05-17 18:14:43 +00002345- Issue #1096: Prevent a segfault from getting the repr of a very
2346 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002347
Brett Cannon1e534b52007-09-07 04:18:30 +00002348- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002349 PyObject_Call() never calling back out to Python code to trigger
2350 recursion depth updates/checks. Required the creation of a static
2351 RuntimeError instance in case normalizing an exception put the
2352 recursion check value past its limit. Fixes crashers
2353 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002354

Neal Norwitz0ac60192007-05-27 04:08:54 +00002368- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002369 __*__ attributes. (Some already existed, e.g., __doc__ and
2370 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002371
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002372- Add -3 option to the interpreter to warn about features that are
2373 deprecated and will be changed/removed in Python 3.0.
2374
Georg Brandl2134e752007-05-21 20:34:16 +00002375- Patch #1686487: you can now pass any mapping after '**' in function
2376 calls.
2377
Collin Winter62903052007-05-18 23:11:24 +00002378- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002379 "except E as target:". This is to provide forwards compatibility
2380 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002381
Brett Cannon229cee22007-05-05 01:34:02 +00002382- Deprecate BaseException.message as per PEP 352.
2383
Georg Brandl3ee81df2008-05-17 18:14:43 +00002384- Issue #1303614: don't expose object's __dict__ when the dict is

2386
Vinay Sajip8549ce32007-05-06 17:53:37 +00002387- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002388 setting a plain string, ie don't expand to single letter identifiers.
2389
Raymond Hettinger13936692007-04-11 18:40:58 +00002390- Request #1191699: Slices can now be pickled.
2391
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002392- Request #1193128: str.translate() now allows a None argument for
2393 translations that only remove characters without re-mapping the
2394 remaining characters.
2395
Georg Brandl5cb76c12007-03-21 09:00:39 +00002396- Patch #1682205: a TypeError while unpacking an iterable is no longer
2397 masked by a generic one with the message "unpack non-sequence".
2398
Neal Norwitzaa754b72007-03-21 06:39:48 +00002399- Remove unused file Python/fmod.c.
2400
Guido van Rossum143b5642007-03-23 04:58:42 +00002401- Bug #1683368: The object.__init__() and object.__new__() methods are
2402 now stricter in rejecting excess arguments. The only time when
2403 either allows excess arguments is when it is not overridden and the
2404 other one is. For backwards compatibility, when both are
2405 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002406 warning later). Also, type.__init__() insists on the same signature
2407 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002408
Georg Brandl3ee81df2008-05-17 18:14:43 +00002409- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2410 object to complex using its __complex__() method before falling back
2411 to the __float__() method. Therefore, the functions in the cmath
2412 module now can operate on objects that define a __complex__()
2413 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002414
Georg Brandl3ee81df2008-05-17 18:14:43 +00002415- Patch #1623563: allow __class__ assignment for classes with
2416 __slots__. The old and the new class are still required to have the
2417 same slot names.

2424 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002425
Georg Brandl3ee81df2008-05-17 18:14:43 +00002426- Patch #1680015: Don't modify __slots__ tuple if it contains an

2430
Georg Brandl7b9c5552007-03-12 14:30:05 +00002431- Bug #1678647: write a newline after printing an exception in any
2432 case, even when converting the value to a string failed.
2433
Georg Brandl871f1bc2007-03-12 13:17:36 +00002434- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002435 its argument, if it exists. If not, it will work like before. This
2436 allows customizing the output of dir() in the presence of a
2437 __getattr__().

2446 parthensized forms. This means complex(repr(x)) now works instead of
2447 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002448
Georg Brandlaa2321b2007-03-07 00:40:28 +00002449- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002450 makes the filenames the warning module prints much more sensible
2451 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002464- Patch #1674228: when assigning a slice (old-style), check for the
2465 sq_ass_slice instead of the sq_slice slot.
2466
Georg Brandl3ee81df2008-05-17 18:14:43 +00002467- When printing an unraisable error, don't print exceptions. before
2468 the name. This duplicates the behavior whening normally printing
2469 exceptions.

3098 exception.

Thomas Hellerd2ea4a22006-10-17 19:30:48 +00003309- ctypes callback functions only support 'fundamental' data types as
3310 result type. Raise an error when something else is used. This is a
3311 partial fix for Bug #1574584.
3312
Georg Brandl3ee81df2008-05-17 18:14:43 +00003313- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003379- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3380 with RFC 3207 and forgets any knowledge obtained from the server not
3381 obtained from the TLS negotiation itself. Patch contributed by Bill
3382 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003383
Georg Brandl3ee81df2008-05-17 18:14:43 +00003384- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003385 that the SMTP.starttls() caller no longer needs to call ehlo()
3386 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003387 does not claim to support starttls. Adds the
3388 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3389 Fenner.

Georg Brandl56112892008-01-20 13:59:46 +00003426- Patch #1648: added ``sys.getprofile()`` and ``sys.gettrace()``.
3427
Georg Brandl3ee81df2008-05-17 18:14:43 +00003428- Patch #1663329: added ``os.closerange()`` function to quickly close

Georg Brandl3ee81df2008-05-17 18:14:43 +00003431- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00003432 works as expected. ``mmap.find`` also takes an optional ``end``

3469 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3470 silently miscode subclasses of those types. Now, it raises a
3471 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003472

Georg Brandl3ee81df2008-05-17 18:14:43 +00003487 time so that opening a database previously created with the DB_DUP
3488 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3489 opens. Specifically: dictionary assignment to a DB object will
3490 replace all values for a given key when the database allows
3491 duplicate values. DB users should use DB.put(k, v) when they want
3492 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003493

3499 characters with ASCII value less than 32. Also, it correctly quotes
3500 dots only if they occur on a single line, as opposed to the previous
3501 behavior of quoting dots if they are the second character of any
3502 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003503

3825-----
3826
Georg Brandl3ee81df2008-05-17 18:14:43 +00003827- Unified naming convention for free lists and their limits. All free
3828 lists in Object/ are named ``free_list``, the counter ``numfree``
3829 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
3830 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003831
Georg Brandl3ee81df2008-05-17 18:14:43 +00003832- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3833 to ``PyTuple_SetItem``, it can be used to populate a brand new
3834 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00003835
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003836- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003838- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
3839 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
3840 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003841
3842- Patch #1720595: add T_BOOL to the range of structmember types.
3843
3844- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
3845 ``PyFloat_GetInfo()`` to the float API.
3846
Georg Brandl3ee81df2008-05-17 18:14:43 +00003847- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3848 of w# format code incorrectly truncated the length to an int, even
3849 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3850 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003851
Georg Brandl3ee81df2008-05-17 18:14:43 +00003852- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
3853 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003855- PEP 3123: Provide forward compatibility with Python 3.0, while
3856 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
3857 and PyVarObject_HEAD_INIT.

3860 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003861
3862- Patch #1733960: Allow T_LONGLONG to accept ints.

3869
3870- Fix some leftovers from the conversion from int to Py_ssize_t
3871 (relevant to strings and sequences of more than 2**31 items).
3872
3873- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3874 outside of pystate.c and should not be necessary.
3875
Georg Brandl3ee81df2008-05-17 18:14:43 +00003876- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3877 absolute imports. In earlier versions they might have used relative
3878 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003879
Georg Brandl3ee81df2008-05-17 18:14:43 +00003880- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3881 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003882
Georg Brandl3ee81df2008-05-17 18:14:43 +00003883- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
3884 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003890- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3891 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3892 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3893 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003894

Georg Brandl3ee81df2008-05-17 18:14:43 +00003908- Removed the macfs module. It had been deprecated since Python 2.5.
3909 This lead to the deprecation of macostools.touched() as it relied
3910 solely on macfs and was a no-op under OS X.
