Nick Coghlanbb0996c2006-09-03 01:20:46 +00007What's New in Python 2.6 alpha 1?
8=================================
Martin v. Löwis2eb8c4f2006-08-18 03:47:18 +00009
Guido van Rossum901464f2007-12-08 04:38:23 +000010*Release date: XX-XXX-2008*
Neal Norwitz92422fb2006-08-18 03:57:54 +000011
12Core and builtins
13-----------------
14
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +000015- Fixed several potential crashes, all caused by specially crafted __del__
16 methods exploiting objects in temporarily inconsistent state.
17
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +000018- Issue #2115: Important speedup in setting __slot__ attributes. Also
19 prevent a possible crash: an Abstract Base Class would try to access a slot
20 on a registered virtual subclass.
21
Christian Heimes2f0da532008-02-15 06:57:08 +000022- Fixed repr() and str() of complex numbers with infinity or nan as real or
23 imaginary part.
24
Christian Heimes3b718a72008-02-14 12:47:33 +000025- Clear all free list during a gc.collect() of the highest generation in order
26 to allow pymalloc to free more arenas. Python may give back memory to the
27 OS earlier.
28
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +000029- Issue #2045: Fix an infinite recursion triggered when printing a subclass of
30 collections.defaultdict, if its default_factory is set to a bound method.
31
Christian Heimesf75dbef2008-02-08 00:11:31 +000032- Fixed a minor memory leak in dictobject.c. The content of the free
33 list was not freed on interpreter shutdown.
34
Christian Heimes6075a822008-02-06 12:44:34 +000035- Limit free list of method and builtin function objects to 256 entries
36 each.
37
Amaury Forgeot d'Arc578a8ca2008-02-04 20:53:14 +000038- Patch #1953: Added ``sys._compact_freelists()`` and the C API functions
39 ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +000040 to compact the internal free lists of pre-allocted ints and floats.
41
Christian Heimes951cc0f2008-01-31 23:08:23 +000042- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
43 Python expected the return type int but the fork familie returns pi_t.
44
Mark Dickinson105be772008-01-31 22:17:37 +000045- Issue #1678380: Fix a bug that identifies 0j and -0j when they appear
46 in the same code unit.
47
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +000048- Issue #2025 : Add tuple.count() and tuple.index() methods to comply with
49 the collections.Sequence API.
50
Christian Heimes4d4f2702008-01-30 11:32:37 +000051- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and linebreak
52 detection
53
Christian Heimes422051a2008-02-04 18:00:12 +000054- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear the
Christian Heimes908caac2008-01-27 23:34:59 +000055 internal lookup cache for ref leak tests.
56
Georg Brandl0cdf9a32008-01-26 14:14:20 +000057- Patch #1473257: generator objects gain a gi_code attribute. This is the
58 same object as the func_code attribute of the function that produced the
59 generator.
60
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +000061- Issue #1920: "while 0" statements were completely removed by the compiler,
62 even in the presence of an "else" clause, which is supposed to be run when
63 the condition is false. Now the compiler correctly emits bytecode for the
64 "else" suite.
65
Guido van Rossumeead05f2008-01-24 18:21:02 +000066- A few crashers fixed: weakref_in_del.py (issue #1377858);
67 loosing_dict_ref.py (issue #1303614, test67.py);
68 borrowed_ref_[34].py (not in tracker).
69
Vinay Sajipd7cf32e2008-01-24 12:43:33 +000070- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +000071 suppressed while an extension is loaded by calling SetErrorMode in
72 dynload_win.c. The error is still reported properly.
73
Christian Heimes082c9b02008-01-23 14:20:50 +000074- Bug #1915: Python compiles with --enable-unicode=no again. However
75 several extension methods and modules do not work without unicode
76 support.
77
Georg Brandl26543b12008-01-21 18:36:51 +000078- Issue #1882: when compiling code from a string, encoding cookies in the
79 second line of code were not always recognized correctly.
80
Georg Brandl14404b62008-01-19 19:27:05 +000081- Issue #1679: "0x" was taken as a valid integer literal.
82
Georg Brandl6caad7d2008-01-26 14:19:22 +000083- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +000084 added.
85
Christian Heimesc94e2b52008-01-14 04:13:37 +000086- sys.float_info / PyFloat_GetInfo: The floating point information
87 object was converted from a dict to a specialized structseq object.
88
Christian Heimesf31b69f2008-01-14 03:42:48 +000089- Patch #1816: Added sys.flags structseq. It exposes the status of most
Vinay Sajip2bdc48c2008-01-21 18:16:05 +000090 command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +000091
Georg Brandl6caad7d2008-01-26 14:19:22 +000092- Objects/structseq.c: Implemented new structseq representation. The patch
Christian Heimesf31b69f2008-01-14 03:42:48 +000093 makes structseqs (e.g. the return value of os.stat) more readable.
Christian Heimes9c201962008-01-14 03:33:52 +000094
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +000095- Patch #1700288: added a type attribute cache that caches method accesses,
96 resulting in speedups in heavily object-oriented code.
97
Neal Norwitz3fc15b82008-01-10 05:42:58 +000098- Bug #1776: __import__() no longer accepts filenames on any platform.
99 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +0000100
Georg Brandlaed6c662008-01-07 17:25:53 +0000101- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
102
Georg Brandl2da0fce2008-01-07 17:09:35 +0000103- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE envvar
104 and sys.dont_write_bytecode attribute. All these can be set to forbid Python
105 to attempt to write compiled bytecode files.
106
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +0000107- Improve some exception messages when Windows fails to load an extension
108 module. Now we get for example '%1 is not a valid Win32 application' instead
109 of 'error code 193'.
110
Christian Heimes8267d1d2008-01-04 00:37:34 +0000111- Bug #1481296: Fixed long(float('nan'))!=0L.
112
Christian Heimeseebb79c2008-01-03 22:32:26 +0000113- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x, y)
114 functions.
Christian Heimese2ca4242008-01-03 20:23:15 +0000115
Christian Heimes0a8143f2007-12-18 23:22:54 +0000116- Issue #1635: Platform independent creation and representation of NaN
117 and INF. float("nan"), float("inf") and float("-inf") now work on every
118 platform with IEEE 754 semantics.
119
Raymond Hettingerfd7ed402007-12-18 21:24:09 +0000120- Compiler now generates simpler and faster code for dictionary literals.
121 The oparg for BUILD_MAP now indicates an estimated dictionary size.
122 There is a new opcode, STORE_MAP, for adding entries to the dictionary.
123
Christian Heimesdb3d6cb2007-12-16 21:39:43 +0000124- Issue #1638: %zd configure test fails on Linux
125
Christian Heimes90e10e72007-12-14 02:35:23 +0000126- Issue #1620: New property decorator syntax was modifying the decorator
127 in place instead of creating a new decorator object.
128
Christian Heimes284d9272007-12-10 22:28:56 +0000129- Issue #1580: New free format floating point representation based on
130 "Floating-Point Printer Sample Code", by Robert G. Burger. For example
131 repr(11./5) now returns '2.2' instead of '2.2000000000000002'.
132
Skip Montanaro26015492007-12-08 15:33:24 +0000133- Issue #1538: Avoid copying string in split/rsplit if the split
134 char is not found.
135
Andrew M. Kuchling395fe442007-12-05 13:27:20 +0000136- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +0000137 SystemError.
138
Nick Coghlanef01d822007-12-03 12:55:17 +0000139- PEP 366: Allow explicit relative imports when executing modules
140 inside packages with the -m switch via a new module level
141 __package__ attribute.
142
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +0000143- Issue #1402: Fix a crash on exit, when another thread is still running, and
144 if the deallocation of its frames somehow calls the PyGILState_Ensure() /
145 PyGILState_Release() functions.
146
Christian Heimes28104c52007-11-27 23:16:44 +0000147- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
148
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000149- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +0000150 attribute of an empty cell object.
151
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +0000152- Issue #1460: The utf-7 incremental decoder did not accept truncated input.
153 It now correctly saves its state between chunks of data.
154
Nick Coghlan327a39b2007-11-18 11:56:28 +0000155- Patch #1739468: Directories and zipfiles containing a __main__.py file can
156 now be directly executed by passing their name to the interpreter. The
157 directory/zipfile is automatically inserted as the first entry in sys.path.
158
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +0000159- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
160 generator expression when at the same time the executed code is closing a
161 paused generator.
162
Raymond Hettinger1760c8a2007-11-08 02:52:43 +0000163- sets and frozensets now have an isdisjoint() method.
164
Raymond Hettinger3f8caa32007-10-24 01:28:33 +0000165- optimize the performance of builtin.sum().
166
Neal Norwitz44f326e2007-10-05 05:29:17 +0000167- Fix warnings found by the new version of the Coverity checker.
168
Raymond Hettinger8f669372007-10-03 21:18:11 +0000169- The enumerate() builtin function is no longer bounded to sequences smaller
170 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
171 shifts from ints to longs.
172
Brett Cannon0b14f242007-09-30 19:45:10 +0000173- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
174 having a self-referential tuple, which is possible from C code. Nor did
175 object's tp_str consider that a type's tp_str could do something that could
176 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
177 respectively, fixed the issues.
178
Brett Cannon01531592007-09-17 03:28:34 +0000179- Issue #1164: It was possible to trigger deadlock when using the 'print'
180 statement to write to a file since the GIL was not released as needed. Now
181 PyObject_Print() does the right thing along with various tp_print
182 implementations of the built-in types and those in the collections module.
183
Brett Cannon4c20bc42007-09-11 21:02:28 +0000184- Issue #1147: Exceptions were directly allowing string exceptions in their
185 throw() method even though string exceptions no longer allowed.
186
Brett Cannona0c05512007-09-10 21:38:27 +0000187- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
188 list by using the recursion counter.
189
Brett Cannon1e534b52007-09-07 04:18:30 +0000190- Issue #1202533: Fix infinite recursion calls triggered by calls to
191 PyObject_Call() never calling back out to Python code to trigger recursion
192 depth updates/checks. Required the creation of a static RuntimeError
193 instance in case normalizing an exception put the recursion check value past
194 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
195
Martin v. Löwisa5136192007-09-04 14:19:28 +0000196- Patch #1031213: Decode source line in SyntaxErrors back to its original source
197 encoding.
198
Georg Brandl7c3b50d2007-07-12 08:38:00 +0000199- Patch #1673759: add a missing overflow check when formatting floats
200 with %G.
201
Neal Norwitzdb2b1b32007-06-11 07:36:24 +0000202- Prevent expandtabs() on string and unicode objects from causing a segfault
203 when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +0000204
Martin v. Löwisda587ab2007-06-08 17:29:20 +0000205- Bug #1733488: Fix compilation of bufferobject.c on AIX.
206
Georg Brandl25497a12007-06-01 19:20:27 +0000207- Bug #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +0000208
Neal Norwitz0ac60192007-05-27 04:08:54 +0000209- Add new attribute names for function objects. All the func_* become
210 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
211
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +0000212- Add -3 option to the interpreter to warn about features that are
213 deprecated and will be changed/removed in Python 3.0.
214
Georg Brandl2134e752007-05-21 20:34:16 +0000215- Patch #1686487: you can now pass any mapping after '**' in function
216 calls.
217
Collin Winter62903052007-05-18 23:11:24 +0000218- except clauses may now be spelled either "except E, target:" or
219 "except E as target:". This is to provide forwards compatibility with
220 Python 3.0.
221
Brett Cannon229cee22007-05-05 01:34:02 +0000222- Deprecate BaseException.message as per PEP 352.
223
Armin Rigo9790a272007-05-02 19:23:31 +0000224- Bug #1303614: don't expose object's __dict__ when the dict is
225 inherited from a builtin base.
226
Vinay Sajip8549ce32007-05-06 17:53:37 +0000227- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +0000228 setting a plain string, ie don't expand to single letter identifiers.
229
Raymond Hettinger13936692007-04-11 18:40:58 +0000230- Request #1191699: Slices can now be pickled.
231
Raymond Hettinger4db5fe92007-04-12 04:10:00 +0000232- Request #1193128: str.translate() now allows a None argument for
233 translations that only remove characters without re-mapping the
234 remaining characters.
235
Georg Brandl5cb76c12007-03-21 09:00:39 +0000236- Patch #1682205: a TypeError while unpacking an iterable is no longer
237 masked by a generic one with the message "unpack non-sequence".
238
Neal Norwitzaa754b72007-03-21 06:39:48 +0000239- Remove unused file Python/fmod.c.
240
Guido van Rossum143b5642007-03-23 04:58:42 +0000241- Bug #1683368: The object.__init__() and object.__new__() methods are
242 now stricter in rejecting excess arguments. The only time when
243 either allows excess arguments is when it is not overridden and the
244 other one is. For backwards compatibility, when both are
245 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +0000246 warning later). Also, type.__init__() insists on the same signature
247 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +0000248
Georg Brandl2b869942007-03-17 16:08:45 +0000249- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
250 to complex using its __complex__() method before falling back to the
251 __float__() method. Therefore, the functions in the cmath module now
252 can operate on objects that define a __complex__() method.
253
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +0000254- Patch #1623563: allow __class__ assignment for classes with __slots__.
255 The old and the new class are still required to have the same slot names.
256
Collin Winter77c67bd2007-03-16 04:11:30 +0000257- Patch #1642547: Fix an error/crash when encountering syntax errors in
258 complex if statements.
259
Žiga Seilnacht20f43d32007-03-15 11:44:55 +0000260- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
261 is called with an object that is faking its type.
262
Žiga Seilnacht71436f02007-03-14 12:24:09 +0000263- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
264 name.
265
Georg Brandl5240d742007-03-13 20:46:32 +0000266- Patch #1444529: the builtin compile() now accepts keyword arguments.
267
Georg Brandl7b9c5552007-03-12 14:30:05 +0000268- Bug #1678647: write a newline after printing an exception in any
269 case, even when converting the value to a string failed.
270
Georg Brandl871f1bc2007-03-12 13:17:36 +0000271- The dir() function has been extended to call the __dir__() method on
272 its argument, if it exists. If not, it will work like before. This allows
273 customizing the output of dir() in the presence of a __getattr__().
274
Collin Winter276887b2007-03-12 16:11:39 +0000275- Patch #922167: Python no longer segfaults when faced with infinitely
276 self-recursive reload() calls (as reported by bug #742342).
277
Žiga Seilnacht89032082007-03-11 15:54:54 +0000278- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
279
Collin Wintere38051d2007-03-09 20:33:07 +0000280- Patch #1491866: change the complex() constructor to allow parthensized
281 forms. This means complex(repr(x)) now works instead of raising a
282 ValueError.
283
Georg Brandlaa2321b2007-03-07 00:40:28 +0000284- Patch #703779: unset __file__ in __main__ after running a file. This
285 makes the filenames the warning module prints much more sensible when
286 a PYTHONSTARTUP file is used.
287
Georg Brandl49aafc92007-03-07 00:34:46 +0000288- Variant of patch #697613: don't exit the interpreter on a SystemExit

Collin Winter22c42ba2007-03-10 02:51:26 +0000843
Andrew M. Kuchlinge45a77a2008-01-19 16:26:13 +0000844- Patch #742598: Add .timeout attribute to SocketServer that calls

864 and TestSuite subclasses (not instances) are no longer accepted in

867 later, with a more cumbersome exception.

1206 tuple, list, dict, set, and frozenset. Formerly, it would silently miscode
1207 subclasses of those types. Now, it raises a ValueError instead.

1223 time so that opening a database previously created with the DB_DUP or
1224 DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
1225 Specifically: dictionary assignment to a DB object will replace all
1226 values for a given key when the database allows duplicate values.
1227 DB users should use DB.put(k, v) when they want to store duplicates; not
1228 DB[k] = v.
1229
Gregory P. Smithac11e022007-11-05 02:56:31 +00001230- Add the bsddb.db.DBEnv.lock_id_free method.

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00001488- Add a FAST_LOOPS build option that speeds-up looping by trading away
1489 periodic threadstate and signal checking in tight loops. By default,
1490 this option is turned-off. It should only be enabled in debugged,
1491 performance critical applications.
1492
Martin v. Löwisd44a4e92007-09-05 11:47:34 +00001493- Patch #786737: Allow building in a tree of symlinks pointing to

1505 returned by python-config if Python was built with --enable-shared
1506 because that prevented the shared library from being used.
1507
Georg Brandl18c47f62007-03-13 10:19:22 +00001508- Patch #1569798: fix a bug in distutils when building Python from a

Neal Norwitz92422fb2006-08-18 03:57:54 +00001538C API
1539-----
1540
Christian Heimes5b970ad2008-02-06 13:33:44 +00001541- Unified naming convention for free lists and their limits. All free lists
1542 in Object/ are named ``free_list``, the counter ``numfree`` and the upper
1543 limit is a macro ``PyName_MAXFREELIST`` inside an #ifndef block.
1544
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00001545- ``PySet_Add()`` can now modify a newly created frozenset. Similarly to
1546 ``PyTuple_SetItem``, it can be used to populate a brand new frozenset; but
1547 it does not steal a reference to the added item.
1548
1549- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
1550
Georg Brandl6caad7d2008-01-26 14:19:22 +00001551- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format and
1552 _FormatV from Python 3.0. Made PyLong_AsSsize_t and PyLong_FromSsize_t
1553 public functions.
1554
1555- Patch #1720595: add T_BOOL to the range of structmember types.
1556
1557- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
1558 ``PyFloat_GetInfo()`` to the float API.
1559
1560- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
1561 format code incorrectly truncated the length to an int, even when
1562 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
1563 results with huge strings.
1564
1565- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE
1566 and Py_REFCNT.
1567
1568- PEP 3123: Provide forward compatibility with Python 3.0, while keeping
1569 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
1570 PyVarObject_HEAD_INIT.
1571
1572- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
1573
1574- Patch #1733960: Allow T_LONGLONG to accept ints.
1575
1576- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
1577
Christian Heimes000a0742008-01-03 22:16:32 +00001578- Added a new API function ``PyImport_ImportModuleNoBlock``.
1579
Georg Brandl6caad7d2008-01-26 14:19:22 +00001580- Bug #1637022: Prefix AST symbols with _Py_.
1581
1582- Fix some leftovers from the conversion from int to Py_ssize_t
1583 (relevant to strings and sequences of more than 2**31 items).
1584
1585- Make _PyGILState_NoteThreadState() static, it was not used anywhere
1586 outside of pystate.c and should not be necessary.
1587
Christian Heimes000a0742008-01-03 22:16:32 +00001588- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do absolute
1589 imports. In earlier versions they might have used relative imports under
1590 some conditions.
1591
Andrew M. Kuchlingadc60ab2008-01-04 02:26:00 +00001592- Added case insensitive comparison methods ``PyOS_stricmp(char*, char*)``
Christian Heimes000a0742008-01-03 22:16:32 +00001593 and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
1594
Neal Norwitz8a267062006-08-19 04:25:29 +00001595- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx macro
1596 so it can be used as an expression.

1600-------
1601
Christian Heimes95d64472008-02-09 19:55:22 +00001602- Patch #1706: Drop support for Win9x, WinME and NT4. Python now requires
1603 Windows 2000 or greater. The _WINVER and NTDDI_VERSION macros are set to
1604 Win2k for x86/32bit builds and WinXP for AMD64 builds.
1605
Martin v. Löwis2607e6c2006-11-21 18:20:25 +00001606- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE
1607 and _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00001617- buildtools now raises a DeprecationWarning.
1618
Brett Cannon5e263512007-05-20 23:17:38 +00001619- Removed the macfs module. It had been deprecated since Python 2.5. This
1620 lead to the deprecation of macostools.touched() as it relied solely on macfs
1621 and was a no-op under OS X.

1630-----------------
1631
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001632- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001633 compared equal or unequal to a string and a UnicodeDecodeError
1634 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001635
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001636 Instead, the equal (==) and unequal (!=) comparison operators will
1637 now issue a UnicodeWarning and interpret the two objects as
1638 unequal. The UnicodeWarning can be filtered as desired using
1639 the warning framework, e.g. silenced completely, turned into an
1640 exception, logged, etc.
1641
1642 Note that compare operators other than equal and unequal will still
1643 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001644
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001645- Fix segfault when doing string formatting on subclasses of long.
1646
1647- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1648 with new-style classes.
1649
1650- Fix bug related to __len__ functions returning negative values with
1651 classic classes.
1652
1653- Patch #1538606, Fix __index__() clipping. There were some problems
1654 discovered with the API and how integers that didn't fit into Py_ssize_t
1655 were handled. This patch attempts to provide enough alternatives
1656 to effectively use __index__.
1657
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001658- Bug #1536021: __hash__ may now return long int; the final hash
1659 value is obtained by invoking hash on the long int.
1660
Thomas Hellerab1049c2006-08-08 17:37:00 +00001661- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1662
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001663- Bug #1535165: fixed a segfault in input() and raw_input() when
1664 sys.stdin is closed.
1665
Thomas Heller74d36f02006-08-04 18:17:40 +00001666- On Windows, the PyErr_Warn function is now exported from
1667 the Python dll again.
1668
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001669- Bug #1191458: tracing over for loops now produces a line event
1670 on each iteration. Fixing this problem required changing the .pyc
1671 magic number. This means that .pyc files generated before 2.5c1
1672 will be regenerated.
1673
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001674- Bug #1333982: string/number constants were inappropriately stored
1675 in the byte code and co_consts even if they were not used, ie
1676 immediately popped off the stack.
1677
Georg Brandle9462c72006-08-04 18:03:37 +00001678- Fixed a reference-counting problem in property().

1681Library
1682-------
1683
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001684- Fix a bug in the ``compiler`` package that caused invalid code to be
1685 generated for generator expressions.
1686
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001687- The distutils version has been changed to 2.5.0. The change to
1688 keep it programmatically in sync with the Python version running
1689 the code (introduced in 2.5b3) has been reverted. It will continue
1690 to be maintained manually as static string literal.
1691
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001692- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001693 and this cannot be converted to the required C type, an exception is
1694 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001695 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001696
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001697- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001698 an exception.
1699
Tim Petersc10c9d02006-09-05 02:18:09 +00001700- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001701 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001702 workarounds for clocks with low resolution, to stop the code yielding
1703 duplicate UUIDs.
1704
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001705- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1706 before raising SystemExit, allowing IDLE to honor quit() and exit().
1707
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001708- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1709
Georg Brandl7a1af772006-08-14 21:55:28 +00001710- Patch #1536071: trace.py should now find the full module name of a
1711 file correctly even on Windows.
1712
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001713- logging's atexit hook now runs even if the rest of the module has
1714 already been cleaned up.
1715
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001716- Bug #1112549, fix DoS attack on cgi.FieldStorage.

1731 raises the correct exceptions.
1732
Thomas Heller1ce433e2006-08-14 16:20:04 +00001733- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1734 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1735
Thomas Heller86720042006-08-14 11:17:48 +00001736- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1737 uses the _as_parameter_ attribute when objects are passed to foreign
1738 function calls. The ctypes version number was changed to 1.0.1.
1739
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001740- Bug #1530559, struct.pack raises TypeError where it used to convert.

1777-----
1778
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001779- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1780
Tim Peters4643c2f2006-08-10 22:45:34 +00001781- Bug #1069160. Internal correctness changes were made to
1782 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1783 the documentation was changed to state that the return value
1784 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001787What's New in Python 2.5 beta 3?
1788================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001789
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001790*Release date: 03-AUG-2006*

1792Core and builtins
1793-----------------
1794
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001795- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001796 returned a long (see PEP 353).
1797
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001798- Bug #1515471: string.replace() accepts character buffers again.
1799
Neal Norwitz07aadb12006-07-30 06:55:48 +00001800- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1801 This provides the proper warning for struct.pack().
1802 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1803
Neal Norwitz0d62a062006-07-30 06:53:31 +00001804- Patch #1531113: Fix augmented assignment with yield expressions.
1805 Also fix a SystemError when trying to assign to yield expressions.
1806
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001807- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1808 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1809 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1810 excessive filesystem operations during imports.
1811
Tim Petersbc24eee2006-07-27 01:14:53 +00001812- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1813 operations on signed longs that are formally undefined by C.
1814 Unfortunately, at least one compiler now cares about that, so complicated
1815 the code to make that compiler happy again.
1816
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001817- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1818
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001819- Patch #1232023: Stop including current directory in search
1820 path on Windows.
1821
Neal Norwitze1fdb322006-07-21 05:32:28 +00001822- Fix some potential crashes found with failmalloc.
1823
Neal Norwitze7563102006-07-17 01:00:16 +00001824- Fix warnings reported by Klocwork's static analysis tool.
1825
Neal Norwitz84be93b2006-07-16 01:50:38 +00001826- Bug #1512814, Fix incorrect lineno's when code within a function
1827 had more than 255 blank lines.
1828
Georg Brandl9dceedb2006-07-12 15:31:17 +00001829- Patch #1521179: Python now accepts the standard options ``--help`` and
1830 ``--version`` as well as ``/?`` on Windows.
1831
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001832- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001833 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001834 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001835
Tim Peters112aad32006-07-19 00:03:19 +00001836- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001837 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001838 new ``sys._current_frames()`` returns a dictionary with one entry,
1839 mapping the faux "thread id" 0 to the current frame.
1840
Ronald Oussoren3075e162006-07-25 20:28:55 +00001841- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001842

1845-------
1846
Facundo Batista6e22be72008-01-19 18:45:46 +00001847- Fix #1693149. Now you can pass several modules separated by
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00001848 comma to trace.py in the same --ignore-module option.
Facundo Batista6e22be72008-01-19 18:45:46 +00001849
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001850- Correction of patch #1455898: In the mbcs decoder, set final=False
1851 for stream decoder, but final=True for the decode function.
1852
Georg Brandl07fec3a2006-08-01 18:49:24 +00001853- os.urandom no longer masks unrelated exceptions like SystemExit or
1854 KeyboardInterrupt.
1855
Tim Peters4643c2f2006-08-10 22:45:34 +00001856- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001857 shutil.copytree on Windows
1858
Georg Brandle34ac7c2006-07-30 11:07:23 +00001859- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1860 refers to file descriptors, not file objects.
1861
Tim Petersc10c9d02006-09-05 02:18:09 +00001862- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001863 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001864 #1513611, and probably others.
1865
Georg Brandledd9b0d2006-07-29 09:33:26 +00001866- Bug #1441397: The compiler module now recognizes module and function
1867 docstrings correctly as it did in Python 2.4.
1868
Tim Peters6f681472006-07-27 23:44:37 +00001869- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1870 lost that tests are sorted by name before being run. This rarely
1871 matters for well-written tests, but can create baffling symptoms if
1872 side effects from one test to the next affect outcomes. ``DocTestFinder``
1873 has been changed to sort the list of tests it returns.
1874
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001875- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001876 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001877
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001878- Bug #978833: Really close underlying socket in _socketobject.close.
1879
Georg Brandl8c036cc2006-08-20 13:15:39 +00001880- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1881 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001882
Georg Brandlcf0c1722006-07-26 07:23:32 +00001883- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1884 to recursive calls and call it with the failing package name.
1885
Martin v. Löwis0b483032006-07-25 09:53:12 +00001886- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1887
Georg Brandlc13c34c2006-07-24 14:09:56 +00001888- Patch #1515343: Fix printing of deprecated string exceptions with a
1889 value in the traceback module.
1890
Greg Ward48fae7a2006-07-23 16:05:51 +00001891- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1892
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001893- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1894
Brett Cannoncaebe222006-07-18 04:41:36 +00001895- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1896 argument tuple. For arguments where zero is illegal, the value is forced to
1897 the minimum value that is correct. This is to support an undocumented but
1898 common way people used to fill in inconsequential information in the time
1899 tuple pre-2.4.
1900
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001901- Patch #1220874: Update the binhex module for Mach-O.
1902
Barry Warsawb110bad2006-07-21 14:51:07 +00001903- The email package has improved RFC 2231 support, specifically for
1904 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1905 (name*0=<blah>) parameter continuations. This may change the types of
1906 values returned from email.message.Message.get_param() and friends.
1907 Specifically in some cases where non-encoded continuations were used,
1908 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1909 will just return the string (since non-encoded continuations don't have
1910 charset and language parts).
1911
1912 Also, whereas % values were decoded in all parameter continuations, they are
1913 now only decoded in encoded parameter parts.
1914
Ronald Oussoren3075e162006-07-25 20:28:55 +00001915- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1916
1917- Bug #1517996: IDLE now longer shows the default Tk menu when a
1918 path browser, class browser or debugger is the frontmost window on MacOS X
1919
Barry Warsaw00decd72006-07-27 23:43:15 +00001920- Patch #1520294: Support for getset and member descriptors in types.py,
1921 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1922 of an object against these built-in types and more importantly, for getting
1923 their docstrings printed in the interactive interpreter's help() function.

1928
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001929- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1930 a socket operation on a socket with a timeout, the exception will be
1931 caught correctly. Previously, the exception was not caught.
1932
Thomas Heller1393d6a2006-07-28 21:43:20 +00001933- Patch #1529514: The _ctypes extension is now compiled on more
1934 openbsd target platforms.
1935
Tim Peters9cab5932006-07-28 00:30:00 +00001936- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1937 a memory leak, affecting pickles and deep copies.
1938
Tim Petersbc24eee2006-07-27 01:14:53 +00001939- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1941
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001942- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1943
Thomas Hellerce049a02006-07-14 17:51:14 +00001944- Patch #1521817: Index range checking on ctypes arrays containing
1945 exactly one element enabled again. This allows iterating over these
1946 arrays, without the need to check the array size before.
1947
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001948- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001949 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001950 /dev/null in certain cases; this is now fixed.
1951
Thomas Heller47d7a062006-07-12 08:43:47 +00001952- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1953 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001954
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001955- Because of a misspelled preprocessor symbol, ctypes was always
1956 compiled without thread support; this is now fixed.
1957
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001958- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1959 methods now allow their database parameter to be None as the
1960 sleepycat API allows.
1961
Matt Flemingec926502006-07-28 11:27:27 +00001962- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1963 bluetooth API compared with Linux and FreeBSD.

1966-----
1967
1968- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1969 how long the test file should take to play. Now accepts taking 2.93 secs
1970 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1971
Georg Brandl4793aa32006-07-28 18:31:39 +00001972- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1973 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1974 run via ``regrtest.py``. Now they do.

1984- PythonLauncher now works correctly when the path to the script contains
1985 characters that are treated specially by the shell (such as quotes).
1986
1987- Bug #1527397: PythonLauncher now launches scripts with the working directory
1988 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001989 directory. That latter was an implementation accident and not what users

Neil Schemenauer0e07b602006-07-09 16:16:34 +00002004- Bug #1501934: The scope of global variables that are locally assigned
2005 using augmented assignment is now correctly determined.
2006
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00002007- Bug #927248: Recursive method-wrapper objects can now safely
2008 be released.
2009
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00002010- Bug #1417699: Reject locale-specific decimal point in float()
2011 and atof().
2012
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00002013- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
2014 omit a default "error" argument for NULL pointer. This allows
2015 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00002016
Neal Norwitzfb48afa2006-07-08 05:31:37 +00002017- Bug #1519018: 'as' is now validated properly in import statements.
2018
Neal Norwitz28746ab2006-07-09 22:14:42 +00002019- On 64 bit systems, int literals that use less than 64 bits are
2020 now ints rather than longs.
2021
Neal Norwitzed657552006-07-10 00:04:44 +00002022- Bug #1512814, Fix incorrect lineno's when code at module scope
2023 started after line 256.
2024
Tim Peters32a83612006-07-10 21:08:24 +00002025- New function ``sys._current_frames()`` returns a dict mapping thread
2026 id to topmost thread stack frame. This is for expert use, and is
2027 especially useful for debugging application deadlocks. The functionality
2028 was previously available in Fazal Majid's ``threadframe`` extension
2029 module, but it wasn't possible to do this in a wholly threadsafe way from
2030 an extension.

2047
Thomas Woutersadd19112006-07-05 11:03:49 +00002048- string.Template() now correctly handles tuple-values. Previously,
2049 multi-value tuples would raise an exception and single-value tuples would
2050 be treated as the value they contain, instead.
2051
Martin v. Löwisede77f52006-07-03 13:01:35 +00002052- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

2077
Brett Cannon53ab5b72006-06-22 16:49:14 +00002078- Bug #1510580: The 'warnings' module improperly required that a Warning
2079 category be either a types.ClassType and a subclass of Warning. The proper
2080 check is just that it is a subclass with Warning as the documentation states.
2081
Georg Brandlad29e632006-06-21 17:45:17 +00002082- The compiler module now correctly compiles the new try-except-finally
2083 statement (bug #1509132).
2084
Neal Norwitz60373cd2006-06-22 06:30:50 +00002085- The wsgiref package is now installed properly on Unix.
2086

2088 shutdown when fileConfig() was called multiple times.
2089
Gerhard Häring762fbd32006-07-02 17:48:30 +00002090- The sqlite3 module did cut off data from the SQLite database at the first
2091 null character before sending it to a custom converter. This has been fixed
2092 now.

2095-----------------
2096
Tim Peters112aad32006-07-19 00:03:19 +00002097- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
2098 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
2099 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00002100
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00002101- Assigning None to pointer type fields in ctypes structures possible
2102 overwrote the wrong fields, this is fixed now.
2103
2104- Fixed a segfault in _ctypes when ctypes.wintypes were imported
2105 on non-Windows platforms.
2106
2107- Bug #1518190: The ctypes.c_void_p constructor now accepts any
2108 integer or long, without range checking.
2109
2110- Patch #1517790: It is now possible to use custom objects in the ctypes
2111 foreign function argtypes sequence as long as they provide a from_param
2112 method, no longer is it required that the object is a ctypes type.
2113
2114- The '_ctypes' extension module now works when Python is configured
2115 with the --without-threads option.
2116
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00002117- Bug #1513646: os.access on Windows now correctly determines write
2118 access, again.
2119
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00002120- Bug #1512695: cPickle.loads could crash if it was interrupted with

2132
Tim Peters32a83612006-07-10 21:08:24 +00002133- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00002134 Previously, the slight difference could cause compilation errors of the
2135 'zlib' module on systems with more than one version of zlib.
2136
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00002137- The MSI compileall step was fixed to also support a TARGETDIR
2138 with spaces in it.

2168Core and builtins
2169-----------------
2170
Georg Brandla56b9152006-06-19 06:35:54 +00002171- Patch #1507676: Error messages returned by invalid abstract object operations
2172 (such as iterating over an integer) have been improved and now include the
2173 type of the offending object to help with debugging.
2174
Brett Cannonea3912b2006-06-13 21:46:41 +00002175- Bug #992017: A classic class that defined a __coerce__() method that returned
2176 its arguments swapped would infinitely recurse and segfault the interpreter.
2177
Neal Norwitz909eb122006-06-12 02:13:21 +00002178- Fix the socket tests so they can be run concurrently.
2179
Neal Norwitzb9845e72006-06-12 02:11:18 +00002180- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00002181 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00002182
Brett Cannon22565aa2006-06-09 22:31:23 +00002183- Bug #532646: object.__call__() will continue looking for the __call__
2184 attribute on objects until one without one is found. This leads to recursion
2185 when you take a class and set its __call__ attribute to an instance of the
2186 class. Originally fixed for classic classes, but this fix is for new-style.
2187 Removes the infinite_rec_3 crasher.
2188
Georg Brandl24250812006-06-09 18:45:48 +00002189- The string and unicode methods startswith() and endswith() now accept
2190 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
2191
Brett Cannonde3b0522006-06-08 17:00:45 +00002192- Buffer objects, at the C level, never used the char buffer
2193 implementation even when the char buffer for the wrapped object was
2194 explicitly requested (originally returned the read or write buffer).
2195 Now a TypeError is raised if the char buffer is not present but is
2196 requested.
2197
Georg Brandlddbaa662006-06-04 21:56:52 +00002198- Patch #1346214: Statements like "if 0: suite" are now again optimized
2199 away like they were in Python 2.4.
2200
Georg Brandlb7c8f542006-05-27 12:30:25 +00002201- Builtin exceptions are now full-blown new-style classes instead of
2202 instances pretending to be classes, which speeds up exception handling
2203 by about 80% in comparison to 2.5a2.
2204
Martin v. Löwisd004fc82006-05-27 08:36:52 +00002205- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
2206 Unicode 4.1.
2207
Georg Brandlf4ef1162006-05-26 18:03:31 +00002208- Patch #921466: sys.path_importer_cache is now used to cache valid and
2209 invalid file paths for the built-in import machinery which leads to
2210 fewer open calls on startup.
2211
Tim Peters696cf432006-05-24 21:10:40 +00002212- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
2213 of-2 bases. The largest speedup is for inputs with about 1000 decimal
2214 digits. Conversion from non-power-of-2 bases remains quadratic-time in
2215 the number of input digits (it was and remains linear-time for bases
2216 2, 4, 8, 16 and 32).
2217
Tim Petersb713ec22006-05-23 18:45:30 +00002218- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
2219 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
2220 an integer close to ``sys.maxint``. This was repaired by patch
2221 #1335972, which also gives a nice speedup.
2222
Richard Jonescebbefc2006-05-23 18:28:17 +00002223- Patch #1337051: reduced size of frame objects.
2224
2225- PyErr_NewException now accepts a tuple of base classes as its
2226 "base" parameter.
2227
Richard Jones7c88dcc2006-05-23 10:37:38 +00002228- Patch #876206: function call speedup by retaining allocated frame
2229 objects.
2230
Georg Brandl7b90e162006-05-18 07:01:27 +00002231- Bug #1462152: file() now checks more thoroughly for invalid mode
2232 strings and removes a possible "U" before passing the mode to the
2233 C library function.
2234
Neal Norwitz1004a532006-05-15 07:17:23 +00002235- Patch #1488312, Fix memory alignment problem on SPARC in unicode
2236
Neal Norwitz373f0a72006-05-15 07:04:36 +00002237- Bug #1487966: Fix SystemError with conditional expression in assignment
2238
Martin v. Löwis879768d2006-05-11 13:28:43 +00002239- WindowsError now has two error code attributes: errno, which carries
2240 the error values from errno.h, and winerror, which carries the error
2241 values from winerror.h. Previous versions put the winerror.h values
2242 (from GetLastError()) into the errno attribute.
2243
Martin v. Löwis77736712006-05-04 05:51:03 +00002244- Patch #1475845: Raise IndentationError for unexpected indent.
2245
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00002246- Patch #1479181: split open() and file() from being aliases for each other.
2247
Tim Peters44bd9862006-06-01 13:49:23 +00002248- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
2249 methods were always silently ignored by dictionaries when comparing keys.
2250 They are now passed through (except when using the C API function
2251 ``PyDict_GetItem()``, whose semantics did not change).
2252
2253- Bug #1456209: In some obscure cases it was possible for a class with a
2254 custom ``__eq__()`` method to confuse dict internals when class instances
2255 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
2256 No, you don't have any code that did this ;-)

2259-----------------
2260
Trent Mick960a3f82006-06-28 20:30:41 +00002261- Bug #1295808: expat symbols should be namespaced in pyexpat
2262

2264
Brett Cannon6ee7d012006-06-08 16:23:04 +00002265- Change binascii.hexlify to accept a read-only buffer instead of only a char
2266 buffer and actually follow its documentation.
2267
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00002268- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
2269
Nick Coghlanc649ec52006-05-29 12:43:05 +00002270- Patch #1478788 (modified version): The functional extension module has
2271 been renamed to _functools and a functools Python wrapper module added.
2272 This provides a home for additional function related utilities that are
2273 not specifically about functional programming. See PEP 309.
2274
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00002275- Patch #1493701: performance enhancements for struct module.

2278
Georg Brandl8d3342b2006-05-16 07:38:27 +00002279- Patch #1435422: zlib's compress and decompress objects now have a
2280 copy() method.
2281
Andrew MacIntyre92913322006-06-13 15:04:24 +00002282- Patch #1454481: thread stack size is now tunable at runtime for thread
2283 enabled builds on Windows and systems with Posix threads support.
2284
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002285- On Win32, os.listdir now supports arbitrarily-long Unicode path names
2286 (up to the system limit of 32K characters).
2287
2288- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
2289 As a result, these functions now raise WindowsError instead of OSError.
2290
Tim Peters7a822da2006-05-25 21:50:17 +00002291- ``time.clock()`` on Win64 should use the high-performance Windows
2292 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
2293 Windows platforms).
2294
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002295- Calling Tk_Init twice is refused if the first call failed as that
2296 may deadlock.
2297
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00002298- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
2299 accept it without potentially using an uninitialized pointer.

2307
Gregory P. Smith372b5832006-06-05 18:48:21 +00002308- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
2309 parameter is supplied. [SF pybsddb bug #1477863]
2310
Gregory P. Smith3c228b12006-06-05 23:59:37 +00002311- bsddb: the __len__ method of a DB object has been fixed to return correct
2312 results. It could previously incorrectly return 0 in some cases.
2313 Fixes SF bug 1493322 (pybsddb bug 1184012).
2314
Gregory P. Smithff7d9912006-06-08 05:17:08 +00002315- bsddb: the bsddb.dbtables Modify method now raises the proper error and
2316 aborts the db transaction safely when a modifier callback fails.
2317 Fixes SF python patch/bug #1408584.
2318
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002319- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00002320 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002321 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
2322 database calls that would previously deadlock. [SF python bug #775414]

2352 double-byte encodings.
2353
Tim Peters43898b42006-06-14 04:09:25 +00002354- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2355 guarantee that adjacent triples in the return list always describe
2356 non-adjacent blocks. Previously, a pair of matching blocks could end
2357 up being described by multiple adjacent triples that formed a partition
2358 of the matching pair.

2367
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002368- The wsgiref package has been added to the standard library.
2369
Nick Coghlan676725d2006-06-08 13:54:49 +00002370- The functions update_wrapper() and wraps() have been added to the functools
2371 module. These make it easier to copy relevant metadata from the original
2372 function when writing wrapper functions.
2373
Tim Petersd6a9eef2006-06-05 01:48:21 +00002374- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2375 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002376
Martin v. Löwis3f767792006-06-04 19:36:28 +00002377- Patch #1359618: Speed up charmap encoder by using a trie structure
2378 for lookup.
2379
Tim Petersd609b1a2006-06-02 23:22:51 +00002380- The functions in the ``pprint`` module now sort dictionaries by key
2381 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2382 if and only if its display required more than one line, although that
2383 wasn't documented. The new behavior increases predictability; e.g.,
2384 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2385

Georg Brandlb89316f2006-05-17 15:51:16 +00002396- Patch #1180296: Two new functions were added to the locale module:
2397 format_string() to get the effect of "format % items" but locale-aware,
2398 and currency() to format a monetary number with currency sign.

2405
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002406- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2407 stdout arguments, making it possible to redirect input and output
2408 for remote debugging.
2409
2410- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2411 a couple of issues, notably handling of long file names using the
2412 GNU LONGNAME extension.
2413
2414- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2415 new flag when ``name`` is already the name of an option flag.
2416
2417- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2418 package.
2419
2420- Patch #1472854: make the rlcompleter.Completer class usable on non-
2421 UNIX platforms.

2461Core and builtins
2462-----------------
2463
Thomas Heller1b046642006-04-18 18:51:06 +00002464- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2465 by converting these apis from macros into exported functions again:
2466
2467 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2468 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2469 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2470 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2471 PyRun_String Py_CompileString
2472
Martin v. Löwis45294a92006-04-18 06:24:08 +00002473- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2474
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002475- All uses of PyStructSequence_InitType have been changed to initialize
2476 the type objects only once, even if the interpreter is initialized
2477 multiple times.
2478
Neal Norwitz61546162006-04-14 05:20:28 +00002479- Bug #1454485, array.array('u') could crash the interpreter. This was
2480 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2481 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2482
2483- Py_UNICODE is unsigned. It was always documented as unsigned, but
2484 due to a bug had a signed value in previous versions.
2485
Tim Peters3a5e8b12006-04-11 01:44:07 +00002486- Patch #837242: ``id()`` of any Python object always gives a positive
2487 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2488 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002489 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002490 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002491
Tim Peters3a5e8b12006-04-11 01:44:07 +00002492 def __hash__(self):
2493 return id(self) # WRONG
2494
2495 because a hash result must be a (short) Python int but it was always
2496 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002497 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002498 was always usable as a hash value before this patch. That's no longer
2499 necessarily so.
2500
2501- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002502 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002503 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002504 #1454844)
2505
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002506- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2507 involving generators that have paused outside of any ``try`` or ``with``
2508 blocks. (In 2.5a1, a paused generator that was part of a reference
2509 cycle could not be garbage collected, regardless of whether it was
2510 paused in a ``try`` or ``with`` block.)

Tim Peters711bf302006-04-25 03:31:36 +00002542- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes

2544 or exception is ignored).
2545
Nick Coghlanda2268f2006-04-24 04:37:15 +00002546- Fixed contextlib.nested to cope with exceptions being raised and
2547 caught inside exit handlers.
2548
Greg Wardab05edc2006-04-23 03:47:58 +00002549- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2550 hex, octal, or binary; add ``append_const`` action; keep going if
2551 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2552 added ``epilog`` for better help generation).
2553
Tim Peters21fbd572006-04-21 21:18:10 +00002554- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2555 called from a thread spawned as a side effect of importing a module.
2556
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002557- The pydoc module now supports documenting packages contained in
2558 .zip or .egg files.
2559
2560- The pkgutil module now has several new utility functions, such
2561 as ``walk_packages()`` to support working with packages that are either
2562 in the filesystem or zip files.
2563
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002564- The mailbox module can now modify and delete messages from
2565 mailboxes, in addition to simply reading them. Thanks to Gregory
2566 K. Johnson for writing the code, and to the 2005 Google Summer of
2567 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002568
Tim Petersc7605f22006-04-17 21:12:33 +00002569- The ``__del__`` method of class ``local`` in module ``_threading_local``
2570 returned before accomplishing any of its intended cleanup.
2571
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002572- Patch #790710: Add breakpoint command lists in pdb.

Martin v. Löwis0f48d982006-04-14 14:34:26 +00002605- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2606 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002607 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002608 CXX from --with-cxx-main, see description in README.
2609
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002610- Patch #1429775: Link extension modules with the shared libpython.
2611
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002612- Fixed a libffi build problem on MIPS systems.
2613
Tim Peters8931ff12006-05-13 23:28:20 +00002614- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2615 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2616 and "%zu" for unsigned integers of type ``size_t``.
2617
Anthony Baxter51bcb682006-04-05 14:51:42 +00002618Tests
2619-----
2620
Nick Coghlanda2268f2006-04-24 04:37:15 +00002621- test_contextlib now checks contextlib.nested can cope with exceptions
2622 being raised and caught inside exit handlers.
2623
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002624- test_cmd_line now checks operation of the -m and -c command switches
2625
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002626- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2627 it separately and by hand. It also wasn't cleaning up its changes to
2628 the current Decimal context.
2629
Thomas Woutersabd08882006-04-26 15:53:30 +00002630- regrtest.py now has a -M option to run tests that test the new limits of
2631 containers, on 64-bit architectures. Running these tests is only sensible
2632 on 64-bit machines with more than two gigabytes of memory. The argument
2633 passed is the maximum amount of memory for the tests to use.
2634
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00002635Tools

2637
2638- Added the Python benchmark suite pybench to the Tools/ directory;
2639 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002641Documentation
2642-------------
2643
Tim Petersb06d28c2006-05-12 01:57:59 +00002644- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2645
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002646- PEP 343: Added Context Types section to the library reference
2647 and attempted to bring other PEP 343 related documentation into
2648 line with the implementation and/or python-dev discussions.
2649
Tim Peters8dc73d22006-04-24 02:03:16 +00002650- Bug #1337990: clarified that ``doctest`` does not support examples
2651 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002654What's New in Python 2.5 alpha 1?
2655=================================
2656
Anthony Baxterebed3f62006-04-03 15:03:44 +00002657*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002658
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002659Core and builtins
2660-----------------
2661
Nick Coghlan43832302006-04-23 17:04:07 +00002662- PEP 338: -m command line switch now delegates to runpy.run_module
2663 allowing it to support modules in packages and zipfiles
2664
Martin v. Löwisc661b882006-04-20 04:54:23 +00002665- On Windows, .DLL is not an accepted file name extension for
2666 extension modules anymore; extensions are only found if they
2667 end in .PYD.
2668
Martin v. Löwisea62d252006-04-03 10:56:49 +00002669- Bug #1421664: sys.stderr.encoding is now set to the same value as
2670 sys.stdout.encoding.
2671
Neal Norwitz92e212f2006-04-03 04:48:37 +00002672- __import__ accepts keyword arguments.
2673
Georg Brandlccadf842006-03-31 18:54:53 +00002674- Patch #1460496: round() now accepts keyword arguments.
2675
Anthony Baxter262c00a2006-03-30 10:53:17 +00002676- Fixed bug #1459029 - unicode reprs were double-escaped.
2677
Hye-Shik Changd478f342006-03-23 12:32:36 +00002678- Patch #1396919: The system scope threads are reenabled on FreeBSD
2679 5.4 and later versions.
2680
Neal Norwitze98ccf62006-03-23 05:39:47 +00002681- Bug #1115379: Compiling a Unicode string with an encoding declaration
2682 now gives a SyntaxError.
2683
Georg Brandlabd1ff82006-03-18 07:59:59 +00002684- Previously, Python code had no easy way to access the contents of a
2685 cell object. Now, a ``cell_contents`` attribute has been added
2686 (closes patch #1170323).
2687
Tim Peterscf79aac2006-03-16 01:14:46 +00002688- Patch #1123430: Python's small-object allocator now returns an arena to
2689 the system ``free()`` when all memory within an arena becomes unused
2690 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2691 freed. Some applications will see a drop in virtual memory size now,
2692 especially long-running applications that, from time to time, temporarily
2693 use a large number of small objects. Note that when Python returns an
2694 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002695 platform C library will in turn return that memory to the operating system.
2696 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002697 appears to be effective at least on Microsoft C and gcc-based systems.
2698 Thanks to Evan Jones for hard work and patience.
2699
Georg Brandl533ff6f2006-03-08 18:09:27 +00002700- Patch #1434038: property() now uses the getter's docstring if there is
2701 no "doc" argument given. This makes it possible to legitimately use
2702 property() as a decorator to produce a read-only property.
2703
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002704- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2705 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2706 of requiring an int or long in slicing and a few other contexts, enabling
2707 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2708
Neal Norwitz995acdf2006-03-07 05:01:00 +00002709- Fixed various bugs reported by Coverity's Prevent tool.
2710
Brett Cannonbf364092006-03-01 04:25:17 +00002711- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2712 new exception base class, BaseException, which has a new message attribute.
2713 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2714 Raising a string exception now raises a DeprecationWarning.
2715
Thomas Woutersfb609f42006-02-28 16:37:25 +00002716- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2717 explicitly relative, using 'from .module import name' to mean 'from the same
2718 package as this module is in. Imports without dots still default to the
2719 old relative-then-absolute, unless 'from __future__ import
2720 absolute_import' is used.
2721
Brett Cannona7446e32006-02-27 23:39:10 +00002722- Properly check if 'warnings' raises an exception (usually when a filter set
2723 to "error" is triggered) when raising a warning for raising string
2724 exceptions.
2725
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002726- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002727 The name was removed from Include/code.h.
2728
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002729- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002730
Guido van Rossum1968ad32006-02-25 22:38:04 +00002731- Patch 1433928:
2732 - The copy module now "copies" function objects (as atomic objects).
2733 - dict.__getitem__ now looks for a __missing__ hook before raising
2734 KeyError.
2735
Tim Peters84ef21c2006-02-28 20:39:06 +00002736- PEP 343: with statement implemented. Needs ``from __future__ import
2737 with_statement``. Use of 'with' as a variable will generate a warning.
2738 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002739 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002740 The following objects have __context__ methods:
2741 - The built-in file type.
2742 - The thread.LockType type.
2743 - The following types defined by the threading module:
2744 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2745 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002746
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002747- Fix the encodings package codec search function to only search
2748 inside its own package. Fixes problem reported in patch #1433198.
2749
2750 Note: Codec packages should implement and register their own
2751 codec search function. PEP 100 has the details.
2752
Tim Peters9ea89d22006-06-04 03:26:02 +00002753- PEP 353: Using ``Py_ssize_t`` as the index type.
2754
2755- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2756 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2757 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2758 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2759 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002760
Neal Norwitzfc76d632006-01-10 06:03:13 +00002761- Patch #1400181, fix unicode string formatting to not use the locale.
2762 This is how string objects work. u'%f' could use , instead of .
2763 for the decimal point. Now both strings and unicode always use periods.
2764
Neal Norwitz671b9e32006-01-09 07:07:12 +00002765- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2766 configure would break checking curses.h.
2767
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002768- Bug #959576: The pwd module is now builtin. This allows Python to be
2769 built on UNIX platforms without $HOME set.
2770
Neal Norwitzc10978f2005-12-19 06:07:16 +00002771- Bug #1072182, fix some potential problems if characters are signed.
2772
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002773- Bug #889500, fix line number on SyntaxWarning for global declarations.
2774
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002775- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2776
Neal Norwitze7214a12005-12-18 05:03:17 +00002777- Support for converting hex strings to floats no longer works.
2778 This was not portable. float('0x3') now raises a ValueError.
2779
Barry Warsaw2a38a862005-12-18 01:27:35 +00002780- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002781 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002782 is now displayed in interactive prompt banner.
2783
Georg Brandlfa166682005-12-17 21:45:17 +00002784- Implementation of PEP 341 - Unification of try/except and try/finally.
2785 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002786 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002787
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002788- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2789 now encodes backslash correctly.
2790
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002791- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2792
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002793- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002794 and long longs.
2795
Neal Norwitz67715f02005-11-09 06:59:35 +00002796- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002797 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002798 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002799
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002800- Replaced most Unicode charmap codecs with new ones using the
2801 new Unicode translate string feature in the builtin charmap
2802 codec; the codecs were created from the mapping tables available
2803 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2804 encodings now include a mapping for the Apple logo)
2805
Tim Peterse3547fd2005-12-16 23:13:57 +00002806- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002807
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002808- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002809
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002810- A new AST parser implementation was completed. The abstract
2811 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002812 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002813
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002814- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002815 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2816
Neal Norwitz708e51a2005-10-03 04:48:15 +00002817- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2818
Neal Norwitz11bd1192005-10-03 00:54:56 +00002819- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2820 Provide a warning when a directory is passed on the command line.
2821
Neal Norwitz40d37812005-10-02 01:48:49 +00002822- Fix segfault with invalid coding.
2823
2824- SF bug #772896: unknown encoding results in MemoryError.
2825
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002826- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002827 supported a __len__() method which evaluated to False when the iterator
2828 was empty.
2829
Guido van Rossum630db602005-09-20 18:49:54 +00002830- On 64-bit platforms, when __len__() returns a value that cannot be
2831 represented as a C int, raise OverflowError.
2832
Skip Montanarof8948ca2005-09-19 03:54:46 +00002833- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002834 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002835
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002836- SF bug #893549: parsing keyword arguments was broken with a few format
2837 codes.
2838
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002839- Changes donated by Elemental Security to make it work on AIX 5.3
2840 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2841 bug #105470: test_pwd fails on 64bit system (Opteron).
2842
Guido van Rossum539c6622005-09-14 17:49:54 +00002843- Changes donated by Elemental Security to make it work on HP-UX 11 on
2844 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2845
Georg Brandl4550b8d2005-08-26 06:43:52 +00002846- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002847 (fixes bug #1119418).
2848
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002849- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2850
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002851- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2852 exceptions that cause a function to exit.
2853
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002854- The implementation of set() and frozenset() was revised to use its
2855 own internal data structure. Memory consumption is reduced by 1/3
2856 and there are modest speed-ups as well. The API is unchanged.
2857
Tim Petersde7990b2005-07-17 23:45:23 +00002858- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2859
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002860- SF bug #1229429: PyObject_CallMethod failed to decrement some
2861 reference counts in some error exit cases.
2862
Tim Petersecc6e6a2005-07-10 22:30:55 +00002863- SF bug #1185883: Python's small-object memory allocator took over
2864 a block managed by the platform C library whenever a realloc specified
2865 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002866 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002867 portable way to copy data from the C-managed block into Python's
2868 small-object space without risking a memory fault. Python's small-object
2869 realloc now leaves such blocks under the control of the platform C

Michael W. Hudsonb8963812005-07-05 15:21:58 +00002872- SF bug #1232517: An overflow error was not detected properly when
2873 attempting to convert a large float to an int in os.utime().
2874
Raymond Hettinger3296e692005-06-29 23:29:56 +00002875- SF bug #1224347: hex longs now print with lowercase letters just
2876 like their int counterparts.
2877
Michael W. Hudson188d4362005-06-20 16:52:57 +00002878- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2879 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2880 interpreter states; back out that fix and do a better job (see
2881 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2882 for a longer write-up of the problem).
2883
Michael W. Hudsondf888462005-06-03 14:41:55 +00002884- SF patch #1180995: marshal now uses a binary format by default when
2885 serializing floats.
2886
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002887- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2888 the routines that promise to produce IEEE 754 binary representations
2889 of floats now simply copy bytes around.
2890
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002891- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2892 278.
2893
Brett Cannonc3647ac2005-04-26 03:45:26 +00002894- patch #1109424: int, long, float, complex, and unicode now check for the
2895 proper magic slot for type conversions when subclassed. Previously the
2896 magic slot was ignored during conversion. Semantics now match the way
2897 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002898 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002899 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002900 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002901
Barry Warsawc8d907c2005-04-19 23:43:40 +00002902- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2903 NULL, now raise an AttributeError when attempting to set or delete the
2904 attribute. Previously a TypeError was raised, but this was inconsistent
2905 with the equivalent pure-Python implementation.
2906
Michael W. Hudson774479c2005-04-18 08:46:17 +00002907- It is now safe to call PyGILState_Release() before
2908 PyEval_InitThreads() (note that if there is reason to believe there
2909 are multiple threads around you still must call PyEval_InitThreads()
2910 before using the Python API; this fix is for extension modules that
2911 have no way of knowing if Python is multi-threaded yet).
2912
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002913- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2914 disabled caused a crash.
2915
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002916- Bug #1165306: instancemethod_new allowed the creation of a method
2917 with im_class == im_self == NULL, which caused a crash when called.
2918
Tim Petersecc6e6a2005-07-10 22:30:55 +00002919- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002920 fixes the crash seen in bug #1165761
2921
Raymond Hettinger96229b12005-03-11 06:49:40 +00002922- Added two new builtins, any() and all().
2923
Brett Cannon409d8f22005-03-05 06:47:57 +00002924- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002925 (e.g., ``class C(): pass`` is no longer a syntax error).
2926 Patch #1176012 added support to the 'parser' module and 'compiler' package
2927 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002928
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002929- Patch #1115086: Support PY_LONGLONG in structmember.
2930
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002931- Bug #1155938: new style classes did not check that __init__() was
2932 returning None.
2933
Tim Petersecc6e6a2005-07-10 22:30:55 +00002934- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002935 ('\') with a specific error message.
2936
Martin v. Löwisff232d72005-03-03 09:24:38 +00002937- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2938
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002939- Bug #1124295: the __name__ attribute of file objects was
2940 inadvertently made inaccessible in restricted mode.
2941
Tim Petersecc6e6a2005-07-10 22:30:55 +00002942- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002943 an ferror() call.
2944
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002945- min() and max() now support key= arguments with the same meaning as in
2946 list.sort().
2947
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002948- The peephole optimizer now performs simple constant folding in expressions:
2949 (2+3) --> (5).
2950
Raymond Hettingera422c342005-01-11 03:03:27 +00002951- set and frozenset objects can now be marshalled. SF #1098985.
2952
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002953- Bug #1077106: Poor argument checking could cause memory corruption
2954 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002955
Jeremy Hyltonab630502005-02-04 18:44:06 +00002956- The parser did not complain about future statements in illegal
2957 positions. It once again reports a syntax error if a future
2958 statement occurs after anything other than a doc string.
2959
Neil Schemenauercf52c072005-08-12 17:34:58 +00002960- Change the %s format specifier for str objects so that it returns a
2961 unicode instance if the argument is not an instance of basestring and
2962 calling __str__ on the argument returns a unicode instance.
2963
Tim Petersf4e69282006-02-27 17:15:31 +00002964- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2965 current thread state when the auto-GIL-state machinery knows about
2966 it (since the thread state is being deleted, continuing to remember it
2967 can't help, but can hurt if another thread happens to get created with
2968 the same thread id).
2969

2987
2988- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2989
2990- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002991 is deprecated. The undocumented re.engine variable no longer exists.

2995
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002996- The unicodedata module was updated to the 4.1 version of the Unicode
2997 database. The 3.2 version is still available as unicodedata.db_3_2_0
2998 for applications that require this specific version (such as IDNA).
2999
Neal Norwitzb62c4332006-03-04 18:35:47 +00003000- The timing module is no longer built by default. It was deprecated

3101 the request code argument, which results in more C-like behaviour
3102 for large or negative values.
3103
Tim Petersecc6e6a2005-07-10 22:30:55 +00003104- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

3145 args tuple returned by __reduce__().
3146
Raymond Hettingerb2594052004-12-05 09:25:51 +00003147- itertools.islice() now accepts None for the start and step arguments.
3148 This allows islice() to work more readily with slices:
3149 islice(s.start, s.stop, s.step)

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00003160- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
3161 been renamed to have only a single underscore prefix. This was done to
3162 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003163
Nick Coghlan43832302006-04-23 17:04:07 +00003164- PEP 338: new module runpy defines a run_module function to support
3165 executing modules which provide access to source code or a code object
3166 via the PEP 302 import mechanisms.
3167
Anthony Baxter93f5b932006-04-03 08:05:07 +00003168- The email module's parsedate_tz function now sets the daylight savings

3176 in attribute values.
3177
Anthony Baxterc51ee692006-04-01 00:57:31 +00003178- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00003179 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00003180 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00003181 module will not be built.
3182
Tim Petersc17976e2006-04-01 00:26:53 +00003183- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
3184 aren't officially supported here, and trying to use them will probably
3185 raise an exception some day. But dicts have been allowed, and "mostly
3186 worked", so support for them won't go away without warning.
3187
Georg Brandl338ef7d2006-03-31 18:42:16 +00003188- Bug #1445068: getpass.getpass() can now be given an explicit stream
3189 argument to specify where to write the prompt.
3190

3200 to make it easier to monitor when daemon threads have completed
3201 processing all enqueued tasks. Patch #1455676.
3202
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00003203- popen2.Popen objects now preserve the command in a .cmd attribute.
3204

3206
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00003207- email 4.0 package now integrated. This is largely the same as the email 3.0
3208 package that was included in Python 2.3, except that PEP 8 module names are
3209 now used (e.g. mail.message instead of email.Message). The MIME classes
3210 have been moved to a subpackage (e.g. email.mime.text instead of
3211 email.MIMEText). The old names are still supported for now. Several
3212 deprecated Message methods have been removed and lots of bugs have been
3213 fixed. More details can be found in the email package documentation.
3214
Walter Dörwald40108c92006-03-27 08:15:44 +00003215- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
3216 (a subclass of tuple) that provides incremental decoders and encoders
3217 (a way to use stateful codecs without the stream API). Python functions
3218 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
3219 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
3220 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00003221
Walter Dörwald067db482006-03-15 22:17:27 +00003222- Patch #1359365: Calling next() on a closed StringIO.String object raises
3223 a ValueError instead of a StopIteration now (like file and cString.String do).
3224 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
3225 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00003226
Martin v. Löwis04824ce2006-03-10 21:26:16 +00003227- A regrtest option -w was added to re-run failed tests in verbose mode.

3300 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
3301 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
3302 Ronald L. Rivest offered this advice for Python:
3303
3304 "The consensus of researchers in this area (at least as
3305 expressed at the NIST Hash Function Workshop 10/31/05),
3306 is that SHA-256 is a good choice for the time being, but
3307 that research should continue, and other alternatives may
3308 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00003309
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00003310- Added a subset of Fredrik Lundh's ElementTree package. Available

Raymond Hettingerda99d1c2005-06-21 07:43:58 +00003402- The tokenize module now detects and reports indentation errors.
3403 Bug #1224621.
3404
Raymond Hettinger68c04532005-06-10 11:05:19 +00003405- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00003406 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00003407 the generate_tokens() function now accepts a callable argument that
3408 terminates by raising StopIteration.

Georg Brandl268e61c2005-06-03 14:28:50 +00003412- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
3413 component of the path.
3414
Skip Montanaro174dd222005-05-14 20:54:16 +00003415- Patch #1120353: The xmlrpclib module provides better, more transparent,
3416 support for datetime.{datetime,date,time} objects. With use_datetime set
3417 to True, applications shouldn't have to fiddle with the DateTime wrapper
3418 class at all.
3419
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00003420- distutils.commands.upload was added to support uploading distribution
3421 files to PyPI.
3422
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00003423- distutils.commands.register now encodes the data as UTF-8 before posting
3424 them to PyPI.
3425
Raymond Hettinger267b8682005-03-27 10:47:39 +00003426- decimal operator and comparison methods now return NotImplemented
3427 instead of raising a TypeError when interacting with other types. This
3428 allows other classes to implement __radd__ style methods and have them
3429 work as expected.
3430
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003431- Bug #1163325: Decimal infinities failed to hash. Attempting to
3432 hash a NaN raised an InvalidOperation instead of a TypeError.
3433

3468
Guido van Rossumd0641422005-02-03 15:01:24 +00003469- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3470 disables recursive traversal through instance attributes, which can
3471 be exploited in various ways.
3472
Tim Peterse3547fd2005-12-16 23:13:57 +00003473- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003474 flags on the HTTP listening socket.
3475
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003476- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3477 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3478
Fred Drakefbdeaad2006-07-29 16:56:15 +00003479- Patches #893642, #1039083: add allow_none, encoding arguments to

3485
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003486- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3487
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003488- Enhancements to the csv module:
3489
3490 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003491 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003492 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003493 + Dialect parameter parsing has been re-implemented to improve error
3494 reporting.
3495 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3496 dictates.
3497 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003498 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003499 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003500 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3501 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003502 + reader now allows \r characters to be quoted (previously it only allowed
3503 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003504 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003505 + Dialect classes passed to the module are no longer instantiated by
3506 the module before being parsed (the former validation scheme required
3507 this, but the mechanism was unreliable).
3508 + The dialect registry now contains instances of the internal
3509 C-coded dialect type, rather than references to python objects.
3510 + the internal c-coded dialect type is now immutable.
3511 + register_dialect now accepts the same keyword dialect specifications
3512 as the reader and writer, allowing the user to register dialects
3513 without first creating a dialect class.
3514 + a configurable limit to the size of parsed fields has been added -
3515 previously, an unmatched quote character could result in the entire
3516 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003517 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003518 the parser field size limit (returning the former limit). The initial
3519 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003520 + A line_num attribute has been added to the reader object, which tracks
3521 the number of lines read from the source iterator. This is not
3522 the same as the number of records returned, as records can span
3523 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003524 + reader and writer objects were not being registered with the cyclic-GC.
3525 This has been fixed.
3526
Brett Cannone6539c42005-01-08 02:43:53 +00003527- _DummyThread objects in the threading module now delete self.__block that is
3528 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3529 lock primitives tend to be limited in number and thus should not be wasted on
3530 a _DummyThread object. Fixes bug #1089632.
3531
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003532- The imghdr module now detects Exif files.
3533
Raymond Hettinger6065d322004-12-20 23:51:53 +00003534- StringIO.truncate() now correctly adjusts the size attribute.
3535 (Bug #951915).
3536
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003537- locale.py now uses an updated locale alias table (built using
3538 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3539 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003540 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003541
Raymond Hettinger3557f422004-12-07 12:02:02 +00003542- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3543
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003544- the pickle module no longer accepts the deprecated None option in the
3545 args tuple returned by __reduce__().
3546
Brett Cannon84667c02004-12-07 03:25:18 +00003547- optparse now optionally imports gettext. This allows its use in setup.py.
3548
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003549- the pickle module no longer uses the deprecated bin parameter.
3550
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003551- the shelve module no longer uses the deprecated binary parameter.
3552
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003553- the pstats module no longer uses the deprecated ignore() method.
3554
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003555- the filecmp module no longer uses the deprecated use_statcache argument.
3556
Raymond Hettinger664347b2004-12-04 21:21:53 +00003557- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3558 extended or overridden by subclasses. Formerly, the subclassed method would
3559 be ignored by the rest of the module. (Bug #1078905).
3560
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003561- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003562 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003563
Walter Dörwald36733692004-12-22 12:50:50 +00003564- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3565 once when a size argument is given. This prevents a buffer overflow in the
3566 tokenizer with very long source lines.
3567
Barry Warsaw538561e2006-01-01 21:48:54 +00003568- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3569 immediately after creating the object, without any intervening
3570 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003571
Skip Montanaro05885812005-01-16 20:48:27 +00003572- The reconvert.quote function can now emit triple-quoted strings. The
3573 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003574
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003575- ``UserString.MutableString`` now supports negative indices in
3576 ``__setitem__`` and ``__delitem__``
3577
Greg Ward40407942005-03-05 02:53:17 +00003578- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3579 correctly.
3580
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003581- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3582 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3583 character even if the user has passed a size parameter to get a proper
3584 line ending. Remove the special handling of a "\r\n" that has been split
3585 between two lines.
3586
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003587- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3588 about illegal code points. The codec now supports PEP 293 style error
3589 handlers.
3590
Walter Dörwald78a78b02005-09-01 12:04:29 +00003591- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003592 from the input stream, so that the output is a byte string in the correct
3593 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003594
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003595- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3596 considering it exactly like a '*'.
3597
Walter Dörwald007f8df2005-10-09 19:42:27 +00003598- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3599 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003600
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003601- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3602
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003603- Patch #1413711: Certain patterns of differences were making difflib
3604 touch the recursion limit.
3605
Walter Dörwald58917a62006-03-31 15:26:22 +00003606- Bug #947906: An object oriented interface has been added to the calendar
3607 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003608 called as a script (e.g. via ``python -mcalendar``). Localized month and
3609 weekday names can be ouput (even if an exotic encoding is used) using
3610 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003611
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003612Build
3613-----
3614

3621
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003622- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3623
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003624- Patch #881820: look for openpty and forkpty also in libbsd.
3625
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003626- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3627 The zlib module is now builtin on Windows.
3628
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003629- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3630
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003631- Bug #1189330: configure did not correctly determine the necessary
3632 value of LINKCC if python was built with GCC 4.0.
3633
Trent Mick8321b422005-07-26 02:29:21 +00003634- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3635 vulnerability in zlib 1.2.1 and 1.2.2.
3636
Brett Cannon08cd5982005-04-24 22:26:38 +00003637- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3638 flags that change binary compatibility. Changes were also made to
3639 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003640 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003641
Bob Ippolitoed233462005-03-29 13:47:59 +00003642- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3643 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3644 no longer exists). This configure patch makes things right.
3645
Martin v. Löwise2713be2005-03-08 15:03:08 +00003646- Bug #1158607: Build with --disable-unicode again.
3647
Brett Cannon46d96232005-02-16 00:07:19 +00003648- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3649 defined. Discovered as a result of not being able to build on OS X.
3650
Brett Cannon516592f2004-12-07 00:42:59 +00003651- setup.py now uses the directories specified in LDFLAGS using the -L option
3652 and in CPPFLAGS using the -I option for adding library and include
3653 directories, respectively, for compiling extension modules against. This has
3654 led to the core being compiled using the values in CPPFLAGS. It also removes
3655 the need for the special-casing of both DarwinPorts and Fink for darwin since
3656 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3657 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3658 Fink, ``-I/opt/local/include`` for DarwinPorts).
3659
Brett Cannon43802422005-02-10 20:48:03 +00003660- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3661 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3662 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.

3667
Tim Petersc9d78aa2006-03-26 23:27:58 +00003668- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3669 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3670 is obtained via the ``PyObject_`` family, it must be released via the
3671 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3672 always been officially true, but when Python's small-object allocator was
3673 introduced, an attempt was made to cater to a few extension modules
3674 discovered at the time that obtained memory via ``PyObject_New`` but
3675 released it via ``PyMem_DEL``. It's years later, and if such code still
3676 exists it will fail now (probably with segfaults, but calling wrong
3677 low-level memory management functions can yield many symptoms).
3678
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003679- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003683- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3684 mapping argument now. This string is used as a mapping table. Byte values
3685 greater than the length of the string and 0xFFFE are treated as undefined
3686 mappings.
