12Core and builtins
13-----------------
14
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +000015- Issue #2115: Important speedup in setting __slot__ attributes. Also
16 prevent a possible crash: an Abstract Base Class would try to access a slot
17 on a registered virtual subclass.
18
Christian Heimes2f0da532008-02-15 06:57:08 +000019- Fixed repr() and str() of complex numbers with infinity or nan as real or
20 imaginary part.
21
Christian Heimes3b718a72008-02-14 12:47:33 +000022- Clear all free list during a gc.collect() of the highest generation in order
23 to allow pymalloc to free more arenas. Python may give back memory to the
24 OS earlier.
25
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +000026- Issue #2045: Fix an infinite recursion triggered when printing a subclass of
27 collections.defaultdict, if its default_factory is set to a bound method.
28
Christian Heimesf75dbef2008-02-08 00:11:31 +000029- Fixed a minor memory leak in dictobject.c. The content of the free
30 list was not freed on interpreter shutdown.
31
Christian Heimes6075a822008-02-06 12:44:34 +000032- Limit free list of method and builtin function objects to 256 entries
33 each.
34
Amaury Forgeot d'Arc578a8ca2008-02-04 20:53:14 +000035- Patch #1953: Added ``sys._compact_freelists()`` and the C API functions
36 ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +000037 to compact the internal free lists of pre-allocted ints and floats.
38
Christian Heimes951cc0f2008-01-31 23:08:23 +000039- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
40 Python expected the return type int but the fork familie returns pi_t.
41
Mark Dickinson105be772008-01-31 22:17:37 +000042- Issue #1678380: Fix a bug that identifies 0j and -0j when they appear
43 in the same code unit.
44
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +000045- Issue #2025 : Add tuple.count() and tuple.index() methods to comply with
46 the collections.Sequence API.
47
Christian Heimes4d4f2702008-01-30 11:32:37 +000048- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and linebreak
49 detection
50
Christian Heimes422051a2008-02-04 18:00:12 +000051- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear the
Christian Heimes908caac2008-01-27 23:34:59 +000052 internal lookup cache for ref leak tests.
53
Georg Brandl0cdf9a32008-01-26 14:14:20 +000054- Patch #1473257: generator objects gain a gi_code attribute. This is the
55 same object as the func_code attribute of the function that produced the
56 generator.
57
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +000058- Issue #1920: "while 0" statements were completely removed by the compiler,
59 even in the presence of an "else" clause, which is supposed to be run when
60 the condition is false. Now the compiler correctly emits bytecode for the
61 "else" suite.
62
Guido van Rossumeead05f2008-01-24 18:21:02 +000063- A few crashers fixed: weakref_in_del.py (issue #1377858);
64 loosing_dict_ref.py (issue #1303614, test67.py);
65 borrowed_ref_[34].py (not in tracker).
66
Vinay Sajipd7cf32e2008-01-24 12:43:33 +000067- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +000068 suppressed while an extension is loaded by calling SetErrorMode in
69 dynload_win.c. The error is still reported properly.
70
Christian Heimes082c9b02008-01-23 14:20:50 +000071- Bug #1915: Python compiles with --enable-unicode=no again. However
72 several extension methods and modules do not work without unicode
73 support.
74
Georg Brandl26543b12008-01-21 18:36:51 +000075- Issue #1882: when compiling code from a string, encoding cookies in the
76 second line of code were not always recognized correctly.
77
Georg Brandl14404b62008-01-19 19:27:05 +000078- Issue #1679: "0x" was taken as a valid integer literal.
79
Georg Brandl6caad7d2008-01-26 14:19:22 +000080- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +000081 added.
82
Christian Heimesc94e2b52008-01-14 04:13:37 +000083- sys.float_info / PyFloat_GetInfo: The floating point information
84 object was converted from a dict to a specialized structseq object.
85
Christian Heimesf31b69f2008-01-14 03:42:48 +000086- Patch #1816: Added sys.flags structseq. It exposes the status of most
Vinay Sajip2bdc48c2008-01-21 18:16:05 +000087 command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +000088
Georg Brandl6caad7d2008-01-26 14:19:22 +000089- Objects/structseq.c: Implemented new structseq representation. The patch
Christian Heimesf31b69f2008-01-14 03:42:48 +000090 makes structseqs (e.g. the return value of os.stat) more readable.
Christian Heimes9c201962008-01-14 03:33:52 +000091
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +000092- Patch #1700288: added a type attribute cache that caches method accesses,
93 resulting in speedups in heavily object-oriented code.
94
Neal Norwitz3fc15b82008-01-10 05:42:58 +000095- Bug #1776: __import__() no longer accepts filenames on any platform.
96 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +000097
Georg Brandlaed6c662008-01-07 17:25:53 +000098- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
99
Georg Brandl2da0fce2008-01-07 17:09:35 +0000100- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE envvar
101 and sys.dont_write_bytecode attribute. All these can be set to forbid Python
102 to attempt to write compiled bytecode files.
103
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +0000104- Improve some exception messages when Windows fails to load an extension
105 module. Now we get for example '%1 is not a valid Win32 application' instead
106 of 'error code 193'.
107
Christian Heimes8267d1d2008-01-04 00:37:34 +0000108- Bug #1481296: Fixed long(float('nan'))!=0L.
109
Christian Heimeseebb79c2008-01-03 22:32:26 +0000110- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x, y)
111 functions.
Christian Heimese2ca4242008-01-03 20:23:15 +0000112
Christian Heimes0a8143f2007-12-18 23:22:54 +0000113- Issue #1635: Platform independent creation and representation of NaN
114 and INF. float("nan"), float("inf") and float("-inf") now work on every
115 platform with IEEE 754 semantics.
116
Raymond Hettingerfd7ed402007-12-18 21:24:09 +0000117- Compiler now generates simpler and faster code for dictionary literals.
118 The oparg for BUILD_MAP now indicates an estimated dictionary size.
119 There is a new opcode, STORE_MAP, for adding entries to the dictionary.
120
Christian Heimesdb3d6cb2007-12-16 21:39:43 +0000121- Issue #1638: %zd configure test fails on Linux
122
Christian Heimes90e10e72007-12-14 02:35:23 +0000123- Issue #1620: New property decorator syntax was modifying the decorator
124 in place instead of creating a new decorator object.
125
Christian Heimes284d9272007-12-10 22:28:56 +0000126- Issue #1580: New free format floating point representation based on
127 "Floating-Point Printer Sample Code", by Robert G. Burger. For example
128 repr(11./5) now returns '2.2' instead of '2.2000000000000002'.
129
Skip Montanaro26015492007-12-08 15:33:24 +0000130- Issue #1538: Avoid copying string in split/rsplit if the split
131 char is not found.
132
Andrew M. Kuchling395fe442007-12-05 13:27:20 +0000133- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +0000134 SystemError.
135
Nick Coghlanef01d822007-12-03 12:55:17 +0000136- PEP 366: Allow explicit relative imports when executing modules
137 inside packages with the -m switch via a new module level
138 __package__ attribute.
139
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +0000140- Issue #1402: Fix a crash on exit, when another thread is still running, and
141 if the deallocation of its frames somehow calls the PyGILState_Ensure() /
142 PyGILState_Release() functions.
143
Christian Heimes28104c52007-11-27 23:16:44 +0000144- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
145
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000146- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +0000147 attribute of an empty cell object.
148
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +0000149- Issue #1460: The utf-7 incremental decoder did not accept truncated input.
150 It now correctly saves its state between chunks of data.
151
Nick Coghlan327a39b2007-11-18 11:56:28 +0000152- Patch #1739468: Directories and zipfiles containing a __main__.py file can
153 now be directly executed by passing their name to the interpreter. The
154 directory/zipfile is automatically inserted as the first entry in sys.path.
155
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +0000156- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
157 generator expression when at the same time the executed code is closing a
158 paused generator.
159
Raymond Hettinger1760c8a2007-11-08 02:52:43 +0000160- sets and frozensets now have an isdisjoint() method.
161
Raymond Hettinger3f8caa32007-10-24 01:28:33 +0000162- optimize the performance of builtin.sum().
163
Neal Norwitz44f326e2007-10-05 05:29:17 +0000164- Fix warnings found by the new version of the Coverity checker.
165
Raymond Hettinger8f669372007-10-03 21:18:11 +0000166- The enumerate() builtin function is no longer bounded to sequences smaller
167 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
168 shifts from ints to longs.
169
Brett Cannon0b14f242007-09-30 19:45:10 +0000170- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
171 having a self-referential tuple, which is possible from C code. Nor did
172 object's tp_str consider that a type's tp_str could do something that could
173 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
174 respectively, fixed the issues.
175
Brett Cannon01531592007-09-17 03:28:34 +0000176- Issue #1164: It was possible to trigger deadlock when using the 'print'
177 statement to write to a file since the GIL was not released as needed. Now
178 PyObject_Print() does the right thing along with various tp_print
179 implementations of the built-in types and those in the collections module.
180
Brett Cannon4c20bc42007-09-11 21:02:28 +0000181- Issue #1147: Exceptions were directly allowing string exceptions in their
182 throw() method even though string exceptions no longer allowed.
183
Brett Cannona0c05512007-09-10 21:38:27 +0000184- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
185 list by using the recursion counter.
186
Brett Cannon1e534b52007-09-07 04:18:30 +0000187- Issue #1202533: Fix infinite recursion calls triggered by calls to
188 PyObject_Call() never calling back out to Python code to trigger recursion
189 depth updates/checks. Required the creation of a static RuntimeError
190 instance in case normalizing an exception put the recursion check value past
191 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
192
Martin v. Löwisa5136192007-09-04 14:19:28 +0000193- Patch #1031213: Decode source line in SyntaxErrors back to its original source
194 encoding.
195
Georg Brandl7c3b50d2007-07-12 08:38:00 +0000196- Patch #1673759: add a missing overflow check when formatting floats
197 with %G.
198
Neal Norwitzdb2b1b32007-06-11 07:36:24 +0000199- Prevent expandtabs() on string and unicode objects from causing a segfault
200 when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +0000201
Martin v. Löwisda587ab2007-06-08 17:29:20 +0000202- Bug #1733488: Fix compilation of bufferobject.c on AIX.
203
Georg Brandl25497a12007-06-01 19:20:27 +0000204- Bug #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +0000205
Neal Norwitz0ac60192007-05-27 04:08:54 +0000206- Add new attribute names for function objects. All the func_* become
207 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
208
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +0000209- Add -3 option to the interpreter to warn about features that are
210 deprecated and will be changed/removed in Python 3.0.
211
Georg Brandl2134e752007-05-21 20:34:16 +0000212- Patch #1686487: you can now pass any mapping after '**' in function
213 calls.
214
Collin Winter62903052007-05-18 23:11:24 +0000215- except clauses may now be spelled either "except E, target:" or
216 "except E as target:". This is to provide forwards compatibility with
217 Python 3.0.
218
Brett Cannon229cee22007-05-05 01:34:02 +0000219- Deprecate BaseException.message as per PEP 352.
220
Armin Rigo9790a272007-05-02 19:23:31 +0000221- Bug #1303614: don't expose object's __dict__ when the dict is
222 inherited from a builtin base.
223
Vinay Sajip8549ce32007-05-06 17:53:37 +0000224- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +0000225 setting a plain string, ie don't expand to single letter identifiers.
226
Raymond Hettinger13936692007-04-11 18:40:58 +0000227- Request #1191699: Slices can now be pickled.
228
Raymond Hettinger4db5fe92007-04-12 04:10:00 +0000229- Request #1193128: str.translate() now allows a None argument for
230 translations that only remove characters without re-mapping the
231 remaining characters.
232
Georg Brandl5cb76c12007-03-21 09:00:39 +0000233- Patch #1682205: a TypeError while unpacking an iterable is no longer
234 masked by a generic one with the message "unpack non-sequence".
235
Neal Norwitzaa754b72007-03-21 06:39:48 +0000236- Remove unused file Python/fmod.c.
237
Guido van Rossum143b5642007-03-23 04:58:42 +0000238- Bug #1683368: The object.__init__() and object.__new__() methods are
239 now stricter in rejecting excess arguments. The only time when
240 either allows excess arguments is when it is not overridden and the
241 other one is. For backwards compatibility, when both are
242 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +0000243 warning later). Also, type.__init__() insists on the same signature
244 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +0000245
Georg Brandl2b869942007-03-17 16:08:45 +0000246- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
247 to complex using its __complex__() method before falling back to the
248 __float__() method. Therefore, the functions in the cmath module now
249 can operate on objects that define a __complex__() method.
250
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +0000251- Patch #1623563: allow __class__ assignment for classes with __slots__.
252 The old and the new class are still required to have the same slot names.
253
Collin Winter77c67bd2007-03-16 04:11:30 +0000254- Patch #1642547: Fix an error/crash when encountering syntax errors in
255 complex if statements.
256
Žiga Seilnacht20f43d32007-03-15 11:44:55 +0000257- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
258 is called with an object that is faking its type.
259
Žiga Seilnacht71436f02007-03-14 12:24:09 +0000260- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
261 name.
262
Georg Brandl5240d742007-03-13 20:46:32 +0000263- Patch #1444529: the builtin compile() now accepts keyword arguments.
264
Georg Brandl7b9c5552007-03-12 14:30:05 +0000265- Bug #1678647: write a newline after printing an exception in any
266 case, even when converting the value to a string failed.
267
Georg Brandl871f1bc2007-03-12 13:17:36 +0000268- The dir() function has been extended to call the __dir__() method on
269 its argument, if it exists. If not, it will work like before. This allows
270 customizing the output of dir() in the presence of a __getattr__().
271
Collin Winter276887b2007-03-12 16:11:39 +0000272- Patch #922167: Python no longer segfaults when faced with infinitely
273 self-recursive reload() calls (as reported by bug #742342).
274
Žiga Seilnacht89032082007-03-11 15:54:54 +0000275- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
276
Collin Wintere38051d2007-03-09 20:33:07 +0000277- Patch #1491866: change the complex() constructor to allow parthensized
278 forms. This means complex(repr(x)) now works instead of raising a
279 ValueError.
280
Georg Brandlaa2321b2007-03-07 00:40:28 +0000281- Patch #703779: unset __file__ in __main__ after running a file. This
282 makes the filenames the warning module prints much more sensible when
283 a PYTHONSTARTUP file is used.
284
Georg Brandl49aafc92007-03-07 00:34:46 +0000285- Variant of patch #697613: don't exit the interpreter on a SystemExit
286 exception if the -i command line option or PYTHONINSPECT environment
287 variable is given, but break into the interactive interpreter just like
288 on other exceptions or normal program exit.
289

Collin Winter22c42ba2007-03-10 02:51:26 +0000840
Andrew M. Kuchlinge45a77a2008-01-19 16:26:13 +0000841- Patch #742598: Add .timeout attribute to SocketServer that calls

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

864 later, with a more cumbersome exception.

1203 tuple, list, dict, set, and frozenset. Formerly, it would silently miscode
1204 subclasses of those types. Now, it raises a ValueError instead.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00001219- pybsddb.sf.net Bug #477182: Load the database flags at database open
1220 time so that opening a database previously created with the DB_DUP or
1221 DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
1222 Specifically: dictionary assignment to a DB object will replace all
1223 values for a given key when the database allows duplicate values.
1224 DB users should use DB.put(k, v) when they want to store duplicates; not
1225 DB[k] = v.
1226
Gregory P. Smithac11e022007-11-05 02:56:31 +00001227- Add the bsddb.db.DBEnv.lock_id_free method.

1234 quoting dots if they are the second character of any line.
1235
Georg Brandla47337f2007-03-13 12:34:25 +00001236- Bug #1622896: fix a rare corner case where the bz2 module raised an

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00001485- Add a FAST_LOOPS build option that speeds-up looping by trading away
1486 periodic threadstate and signal checking in tight loops. By default,
1487 this option is turned-off. It should only be enabled in debugged,
1488 performance critical applications.
1489
Martin v. Löwisd44a4e92007-09-05 11:47:34 +00001490- Patch #786737: Allow building in a tree of symlinks pointing to

1502 returned by python-config if Python was built with --enable-shared
1503 because that prevented the shared library from being used.
1504
Georg Brandl18c47f62007-03-13 10:19:22 +00001505- Patch #1569798: fix a bug in distutils when building Python from a

Neal Norwitz92422fb2006-08-18 03:57:54 +00001535C API
1536-----
1537
Christian Heimes5b970ad2008-02-06 13:33:44 +00001538- Unified naming convention for free lists and their limits. All free lists
1539 in Object/ are named ``free_list``, the counter ``numfree`` and the upper
1540 limit is a macro ``PyName_MAXFREELIST`` inside an #ifndef block.
1541
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00001542- ``PySet_Add()`` can now modify a newly created frozenset. Similarly to
1543 ``PyTuple_SetItem``, it can be used to populate a brand new frozenset; but
1544 it does not steal a reference to the added item.
1545
1546- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
1547
Georg Brandl6caad7d2008-01-26 14:19:22 +00001548- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format and
1549 _FormatV from Python 3.0. Made PyLong_AsSsize_t and PyLong_FromSsize_t
1550 public functions.
1551
1552- Patch #1720595: add T_BOOL to the range of structmember types.
1553
1554- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
1555 ``PyFloat_GetInfo()`` to the float API.
1556
1557- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
1558 format code incorrectly truncated the length to an int, even when
1559 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
1560 results with huge strings.
1561
1562- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE
1563 and Py_REFCNT.
1564
1565- PEP 3123: Provide forward compatibility with Python 3.0, while keeping
1566 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
1567 PyVarObject_HEAD_INIT.
1568
1569- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
1570
1571- Patch #1733960: Allow T_LONGLONG to accept ints.
1572
1573- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
1574
Christian Heimes000a0742008-01-03 22:16:32 +00001575- Added a new API function ``PyImport_ImportModuleNoBlock``.
1576
Georg Brandl6caad7d2008-01-26 14:19:22 +00001577- Bug #1637022: Prefix AST symbols with _Py_.
1578
1579- Fix some leftovers from the conversion from int to Py_ssize_t
1580 (relevant to strings and sequences of more than 2**31 items).
1581
1582- Make _PyGILState_NoteThreadState() static, it was not used anywhere
1583 outside of pystate.c and should not be necessary.
1584
Christian Heimes000a0742008-01-03 22:16:32 +00001585- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do absolute
1586 imports. In earlier versions they might have used relative imports under
1587 some conditions.
1588
Andrew M. Kuchlingadc60ab2008-01-04 02:26:00 +00001589- Added case insensitive comparison methods ``PyOS_stricmp(char*, char*)``
Christian Heimes000a0742008-01-03 22:16:32 +00001590 and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
1591
Neal Norwitz8a267062006-08-19 04:25:29 +00001592- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx macro
1593 so it can be used as an expression.

1597-------
1598
Christian Heimes95d64472008-02-09 19:55:22 +00001599- Patch #1706: Drop support for Win9x, WinME and NT4. Python now requires
1600 Windows 2000 or greater. The _WINVER and NTDDI_VERSION macros are set to
1601 Win2k for x86/32bit builds and WinXP for AMD64 builds.
1602
Martin v. Löwis2607e6c2006-11-21 18:20:25 +00001603- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE
1604 and _CRT_NONSTDC_NO_DEPRECATE.
1605

Brett Cannon791d56f2007-05-31 19:40:42 +00001614- buildtools now raises a DeprecationWarning.
1615
Brett Cannon5e263512007-05-20 23:17:38 +00001616- Removed the macfs module. It had been deprecated since Python 2.5. This
1617 lead to the deprecation of macostools.touched() as it relied solely on macfs
1618 and was a no-op under OS X.

1627-----------------
1628
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001629- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001630 compared equal or unequal to a string and a UnicodeDecodeError
1631 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001632
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001633 Instead, the equal (==) and unequal (!=) comparison operators will
1634 now issue a UnicodeWarning and interpret the two objects as
1635 unequal. The UnicodeWarning can be filtered as desired using
1636 the warning framework, e.g. silenced completely, turned into an
1637 exception, logged, etc.
1638
1639 Note that compare operators other than equal and unequal will still
1640 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001641
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001642- Fix segfault when doing string formatting on subclasses of long.
1643
1644- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1645 with new-style classes.
1646
1647- Fix bug related to __len__ functions returning negative values with
1648 classic classes.
1649
1650- Patch #1538606, Fix __index__() clipping. There were some problems
1651 discovered with the API and how integers that didn't fit into Py_ssize_t
1652 were handled. This patch attempts to provide enough alternatives
1653 to effectively use __index__.
1654
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001655- Bug #1536021: __hash__ may now return long int; the final hash
1656 value is obtained by invoking hash on the long int.
1657
Thomas Hellerab1049c2006-08-08 17:37:00 +00001658- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1659
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001660- Bug #1535165: fixed a segfault in input() and raw_input() when
1661 sys.stdin is closed.
1662
Thomas Heller74d36f02006-08-04 18:17:40 +00001663- On Windows, the PyErr_Warn function is now exported from
1664 the Python dll again.
1665
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001666- Bug #1191458: tracing over for loops now produces a line event
1667 on each iteration. Fixing this problem required changing the .pyc
1668 magic number. This means that .pyc files generated before 2.5c1
1669 will be regenerated.
1670
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001671- Bug #1333982: string/number constants were inappropriately stored
1672 in the byte code and co_consts even if they were not used, ie
1673 immediately popped off the stack.
1674
Georg Brandle9462c72006-08-04 18:03:37 +00001675- Fixed a reference-counting problem in property().

1678Library
1679-------
1680
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001681- Fix a bug in the ``compiler`` package that caused invalid code to be
1682 generated for generator expressions.
1683
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001684- The distutils version has been changed to 2.5.0. The change to
1685 keep it programmatically in sync with the Python version running
1686 the code (introduced in 2.5b3) has been reverted. It will continue
1687 to be maintained manually as static string literal.
1688
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001689- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001690 and this cannot be converted to the required C type, an exception is
1691 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001692 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001693
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001694- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001695 an exception.
1696
Tim Petersc10c9d02006-09-05 02:18:09 +00001697- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001698 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001699 workarounds for clocks with low resolution, to stop the code yielding
1700 duplicate UUIDs.
1701
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001702- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1703 before raising SystemExit, allowing IDLE to honor quit() and exit().
1704
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001705- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1706
Georg Brandl7a1af772006-08-14 21:55:28 +00001707- Patch #1536071: trace.py should now find the full module name of a
1708 file correctly even on Windows.
1709
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001710- logging's atexit hook now runs even if the rest of the module has
1711 already been cleaned up.
1712
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001713- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001714

1728 raises the correct exceptions.
1729
Thomas Heller1ce433e2006-08-14 16:20:04 +00001730- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1731 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1732
Thomas Heller86720042006-08-14 11:17:48 +00001733- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1734 uses the _as_parameter_ attribute when objects are passed to foreign
1735 function calls. The ctypes version number was changed to 1.0.1.
1736
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001737- Bug #1530559, struct.pack raises TypeError where it used to convert.
1738 Passing float arguments to struct.pack when integers are expected
1739 now triggers a DeprecationWarning.

1774-----
1775
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001776- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1777
Tim Peters4643c2f2006-08-10 22:45:34 +00001778- Bug #1069160. Internal correctness changes were made to
1779 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1780 the documentation was changed to state that the return value
1781 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001784What's New in Python 2.5 beta 3?

Neal Norwitza1f10902006-07-12 07:28:29 +00001786
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001787*Release date: 03-AUG-2006*

1789Core and builtins
1790-----------------
1791
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001792- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001793 returned a long (see PEP 353).
1794
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001795- Bug #1515471: string.replace() accepts character buffers again.
1796
Neal Norwitz07aadb12006-07-30 06:55:48 +00001797- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1798 This provides the proper warning for struct.pack().
1799 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1800
Neal Norwitz0d62a062006-07-30 06:53:31 +00001801- Patch #1531113: Fix augmented assignment with yield expressions.
1802 Also fix a SystemError when trying to assign to yield expressions.
1803
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001804- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1805 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1806 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1807 excessive filesystem operations during imports.
1808
Tim Petersbc24eee2006-07-27 01:14:53 +00001809- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1810 operations on signed longs that are formally undefined by C.
1811 Unfortunately, at least one compiler now cares about that, so complicated
1812 the code to make that compiler happy again.
1813
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001814- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1815
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001816- Patch #1232023: Stop including current directory in search
1817 path on Windows.
1818
Neal Norwitze1fdb322006-07-21 05:32:28 +00001819- Fix some potential crashes found with failmalloc.
1820
Neal Norwitze7563102006-07-17 01:00:16 +00001821- Fix warnings reported by Klocwork's static analysis tool.
1822
Neal Norwitz84be93b2006-07-16 01:50:38 +00001823- Bug #1512814, Fix incorrect lineno's when code within a function
1824 had more than 255 blank lines.
1825
Georg Brandl9dceedb2006-07-12 15:31:17 +00001826- Patch #1521179: Python now accepts the standard options ``--help`` and
1827 ``--version`` as well as ``/?`` on Windows.
1828
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001829- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001830 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001831 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001832
Tim Peters112aad32006-07-19 00:03:19 +00001833- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001834 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001835 new ``sys._current_frames()`` returns a dictionary with one entry,
1836 mapping the faux "thread id" 0 to the current frame.
1837
Ronald Oussoren3075e162006-07-25 20:28:55 +00001838- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001839
Ronald Oussoren3075e162006-07-25 20:28:55 +00001840
Neal Norwitza1f10902006-07-12 07:28:29 +00001841Library
1842-------
1843
Facundo Batista6e22be72008-01-19 18:45:46 +00001844- Fix #1693149. Now you can pass several modules separated by
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00001845 comma to trace.py in the same --ignore-module option.
Facundo Batista6e22be72008-01-19 18:45:46 +00001846
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001847- Correction of patch #1455898: In the mbcs decoder, set final=False
1848 for stream decoder, but final=True for the decode function.
1849
Georg Brandl07fec3a2006-08-01 18:49:24 +00001850- os.urandom no longer masks unrelated exceptions like SystemExit or
1851 KeyboardInterrupt.
1852
Tim Peters4643c2f2006-08-10 22:45:34 +00001853- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001854 shutil.copytree on Windows
1855
Georg Brandle34ac7c2006-07-30 11:07:23 +00001856- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1857 refers to file descriptors, not file objects.
1858
Tim Petersc10c9d02006-09-05 02:18:09 +00001859- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001860 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001861 #1513611, and probably others.
1862
Georg Brandledd9b0d2006-07-29 09:33:26 +00001863- Bug #1441397: The compiler module now recognizes module and function
1864 docstrings correctly as it did in Python 2.4.
1865
Tim Peters6f681472006-07-27 23:44:37 +00001866- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1867 lost that tests are sorted by name before being run. This rarely
1868 matters for well-written tests, but can create baffling symptoms if
1869 side effects from one test to the next affect outcomes. ``DocTestFinder``
1870 has been changed to sort the list of tests it returns.
1871
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001872- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001873 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001874
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001875- Bug #978833: Really close underlying socket in _socketobject.close.
1876
Georg Brandl8c036cc2006-08-20 13:15:39 +00001877- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1878 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001879
Georg Brandlcf0c1722006-07-26 07:23:32 +00001880- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1881 to recursive calls and call it with the failing package name.
1882
Martin v. Löwis0b483032006-07-25 09:53:12 +00001883- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1884
Georg Brandlc13c34c2006-07-24 14:09:56 +00001885- Patch #1515343: Fix printing of deprecated string exceptions with a
1886 value in the traceback module.
1887
Greg Ward48fae7a2006-07-23 16:05:51 +00001888- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1889
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001890- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1891
Brett Cannoncaebe222006-07-18 04:41:36 +00001892- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1893 argument tuple. For arguments where zero is illegal, the value is forced to
1894 the minimum value that is correct. This is to support an undocumented but
1895 common way people used to fill in inconsequential information in the time
1896 tuple pre-2.4.
1897
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001898- Patch #1220874: Update the binhex module for Mach-O.
1899
Barry Warsawb110bad2006-07-21 14:51:07 +00001900- The email package has improved RFC 2231 support, specifically for
1901 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1902 (name*0=<blah>) parameter continuations. This may change the types of
1903 values returned from email.message.Message.get_param() and friends.
1904 Specifically in some cases where non-encoded continuations were used,
1905 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1906 will just return the string (since non-encoded continuations don't have
1907 charset and language parts).
1908
1909 Also, whereas % values were decoded in all parameter continuations, they are
1910 now only decoded in encoded parameter parts.
1911
Ronald Oussoren3075e162006-07-25 20:28:55 +00001912- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1913
1914- Bug #1517996: IDLE now longer shows the default Tk menu when a
1915 path browser, class browser or debugger is the frontmost window on MacOS X
1916
Barry Warsaw00decd72006-07-27 23:43:15 +00001917- Patch #1520294: Support for getset and member descriptors in types.py,
1918 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1919 of an object against these built-in types and more importantly, for getting
1920 their docstrings printed in the interactive interpreter's help() function.

1925
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001926- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1927 a socket operation on a socket with a timeout, the exception will be
1928 caught correctly. Previously, the exception was not caught.
1929
Thomas Heller1393d6a2006-07-28 21:43:20 +00001930- Patch #1529514: The _ctypes extension is now compiled on more
1931 openbsd target platforms.
1932
Tim Peters9cab5932006-07-28 00:30:00 +00001933- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1934 a memory leak, affecting pickles and deep copies.
1935
Tim Petersbc24eee2006-07-27 01:14:53 +00001936- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001937 Paul Eggert.
1938
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001939- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1940
Thomas Hellerce049a02006-07-14 17:51:14 +00001941- Patch #1521817: Index range checking on ctypes arrays containing
1942 exactly one element enabled again. This allows iterating over these
1943 arrays, without the need to check the array size before.
1944
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001945- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001946 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001947 /dev/null in certain cases; this is now fixed.
1948
Thomas Heller47d7a062006-07-12 08:43:47 +00001949- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1950 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001951
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001952- Because of a misspelled preprocessor symbol, ctypes was always
1953 compiled without thread support; this is now fixed.
1954
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001955- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1956 methods now allow their database parameter to be None as the
1957 sleepycat API allows.
1958
Matt Flemingec926502006-07-28 11:27:27 +00001959- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1960 bluetooth API compared with Linux and FreeBSD.
1961
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001962Tests
1963-----
1964
1965- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1966 how long the test file should take to play. Now accepts taking 2.93 secs
1967 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1968
Georg Brandl4793aa32006-07-28 18:31:39 +00001969- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1970 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1971 run via ``regrtest.py``. Now they do.

1981- PythonLauncher now works correctly when the path to the script contains
1982 characters that are treated specially by the shell (such as quotes).
1983
1984- Bug #1527397: PythonLauncher now launches scripts with the working directory
1985 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001986 directory. That latter was an implementation accident and not what users

Neil Schemenauer0e07b602006-07-09 16:16:34 +00002001- Bug #1501934: The scope of global variables that are locally assigned
2002 using augmented assignment is now correctly determined.
2003
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00002004- Bug #927248: Recursive method-wrapper objects can now safely
2005 be released.
2006
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00002007- Bug #1417699: Reject locale-specific decimal point in float()
2008 and atof().
2009
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00002010- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
2011 omit a default "error" argument for NULL pointer. This allows
2012 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00002013
Neal Norwitzfb48afa2006-07-08 05:31:37 +00002014- Bug #1519018: 'as' is now validated properly in import statements.
2015
Neal Norwitz28746ab2006-07-09 22:14:42 +00002016- On 64 bit systems, int literals that use less than 64 bits are
2017 now ints rather than longs.
2018
Neal Norwitzed657552006-07-10 00:04:44 +00002019- Bug #1512814, Fix incorrect lineno's when code at module scope
2020 started after line 256.
2021
Tim Peters32a83612006-07-10 21:08:24 +00002022- New function ``sys._current_frames()`` returns a dict mapping thread
2023 id to topmost thread stack frame. This is for expert use, and is
2024 especially useful for debugging application deadlocks. The functionality
2025 was previously available in Fazal Majid's ``threadframe`` extension
2026 module, but it wasn't possible to do this in a wholly threadsafe way from
2027 an extension.

2044
Thomas Woutersadd19112006-07-05 11:03:49 +00002045- string.Template() now correctly handles tuple-values. Previously,
2046 multi-value tuples would raise an exception and single-value tuples would
2047 be treated as the value they contain, instead.
2048
Martin v. Löwisede77f52006-07-03 13:01:35 +00002049- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

Georg Brandl1be63af2006-06-28 20:23:25 +00002073- Fix a bug in the turtle module's end_fill function.
2074
Brett Cannon53ab5b72006-06-22 16:49:14 +00002075- Bug #1510580: The 'warnings' module improperly required that a Warning
2076 category be either a types.ClassType and a subclass of Warning. The proper
2077 check is just that it is a subclass with Warning as the documentation states.
2078
Georg Brandlad29e632006-06-21 17:45:17 +00002079- The compiler module now correctly compiles the new try-except-finally
2080 statement (bug #1509132).
2081
Neal Norwitz60373cd2006-06-22 06:30:50 +00002082- The wsgiref package is now installed properly on Unix.
2083

2085 shutdown when fileConfig() was called multiple times.
2086
Gerhard Häring762fbd32006-07-02 17:48:30 +00002087- The sqlite3 module did cut off data from the SQLite database at the first
2088 null character before sending it to a custom converter. This has been fixed
2089 now.

2092-----------------
2093
Tim Peters112aad32006-07-19 00:03:19 +00002094- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
2095 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
2096 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00002097
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00002098- Assigning None to pointer type fields in ctypes structures possible
2099 overwrote the wrong fields, this is fixed now.
2100
2101- Fixed a segfault in _ctypes when ctypes.wintypes were imported
2102 on non-Windows platforms.
2103
2104- Bug #1518190: The ctypes.c_void_p constructor now accepts any
2105 integer or long, without range checking.
2106
2107- Patch #1517790: It is now possible to use custom objects in the ctypes
2108 foreign function argtypes sequence as long as they provide a from_param
2109 method, no longer is it required that the object is a ctypes type.
2110
2111- The '_ctypes' extension module now works when Python is configured
2112 with the --without-threads option.
2113
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00002114- Bug #1513646: os.access on Windows now correctly determines write
2115 access, again.
2116
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00002117- Bug #1512695: cPickle.loads could crash if it was interrupted with
2118 a KeyboardInterrupt.
2119
Neal Norwitza12aa882006-07-06 06:45:08 +00002120- Bug #1296433: parsing XML with a non-default encoding and
2121 a CharacterDataHandler could crash the interpreter in pyexpat.
2122
Neal Norwitz2a30cd02006-07-10 01:18:57 +00002123- Patch #1516912: improve Modules support for OpenVMS.

Martin v. Löwisd73168d2006-07-14 09:58:55 +00002128- Automate Windows build process for the Win64 SSL module.
2129
Tim Peters32a83612006-07-10 21:08:24 +00002130- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00002131 Previously, the slight difference could cause compilation errors of the
2132 'zlib' module on systems with more than one version of zlib.
2133
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00002134- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +00002164
2165Core and builtins
2166-----------------
2167
Georg Brandla56b9152006-06-19 06:35:54 +00002168- Patch #1507676: Error messages returned by invalid abstract object operations
2169 (such as iterating over an integer) have been improved and now include the
2170 type of the offending object to help with debugging.
2171
Brett Cannonea3912b2006-06-13 21:46:41 +00002172- Bug #992017: A classic class that defined a __coerce__() method that returned
2173 its arguments swapped would infinitely recurse and segfault the interpreter.
2174
Neal Norwitz909eb122006-06-12 02:13:21 +00002175- Fix the socket tests so they can be run concurrently.
2176
Neal Norwitzb9845e72006-06-12 02:11:18 +00002177- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00002178 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00002179
Brett Cannon22565aa2006-06-09 22:31:23 +00002180- Bug #532646: object.__call__() will continue looking for the __call__
2181 attribute on objects until one without one is found. This leads to recursion
2182 when you take a class and set its __call__ attribute to an instance of the
2183 class. Originally fixed for classic classes, but this fix is for new-style.
2184 Removes the infinite_rec_3 crasher.
2185
Georg Brandl24250812006-06-09 18:45:48 +00002186- The string and unicode methods startswith() and endswith() now accept
2187 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
2188
Brett Cannonde3b0522006-06-08 17:00:45 +00002189- Buffer objects, at the C level, never used the char buffer
2190 implementation even when the char buffer for the wrapped object was
2191 explicitly requested (originally returned the read or write buffer).
2192 Now a TypeError is raised if the char buffer is not present but is
2193 requested.
2194
Georg Brandlddbaa662006-06-04 21:56:52 +00002195- Patch #1346214: Statements like "if 0: suite" are now again optimized
2196 away like they were in Python 2.4.
2197
Georg Brandlb7c8f542006-05-27 12:30:25 +00002198- Builtin exceptions are now full-blown new-style classes instead of
2199 instances pretending to be classes, which speeds up exception handling
2200 by about 80% in comparison to 2.5a2.
2201
Martin v. Löwisd004fc82006-05-27 08:36:52 +00002202- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
2203 Unicode 4.1.
2204
Georg Brandlf4ef1162006-05-26 18:03:31 +00002205- Patch #921466: sys.path_importer_cache is now used to cache valid and
2206 invalid file paths for the built-in import machinery which leads to
2207 fewer open calls on startup.
2208
Tim Peters696cf432006-05-24 21:10:40 +00002209- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
2210 of-2 bases. The largest speedup is for inputs with about 1000 decimal
2211 digits. Conversion from non-power-of-2 bases remains quadratic-time in
2212 the number of input digits (it was and remains linear-time for bases
2213 2, 4, 8, 16 and 32).
2214
Tim Petersb713ec22006-05-23 18:45:30 +00002215- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
2216 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
2217 an integer close to ``sys.maxint``. This was repaired by patch
2218 #1335972, which also gives a nice speedup.
2219
Richard Jonescebbefc2006-05-23 18:28:17 +00002220- Patch #1337051: reduced size of frame objects.
2221
2222- PyErr_NewException now accepts a tuple of base classes as its
2223 "base" parameter.
2224
Richard Jones7c88dcc2006-05-23 10:37:38 +00002225- Patch #876206: function call speedup by retaining allocated frame
2226 objects.
2227
Georg Brandl7b90e162006-05-18 07:01:27 +00002228- Bug #1462152: file() now checks more thoroughly for invalid mode
2229 strings and removes a possible "U" before passing the mode to the
2230 C library function.
2231
Neal Norwitz1004a532006-05-15 07:17:23 +00002232- Patch #1488312, Fix memory alignment problem on SPARC in unicode
2233
Neal Norwitz373f0a72006-05-15 07:04:36 +00002234- Bug #1487966: Fix SystemError with conditional expression in assignment
2235
Martin v. Löwis879768d2006-05-11 13:28:43 +00002236- WindowsError now has two error code attributes: errno, which carries
2237 the error values from errno.h, and winerror, which carries the error
2238 values from winerror.h. Previous versions put the winerror.h values
2239 (from GetLastError()) into the errno attribute.
2240
Martin v. Löwis77736712006-05-04 05:51:03 +00002241- Patch #1475845: Raise IndentationError for unexpected indent.
2242
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00002243- Patch #1479181: split open() and file() from being aliases for each other.
2244
Tim Peters44bd9862006-06-01 13:49:23 +00002245- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
2246 methods were always silently ignored by dictionaries when comparing keys.
2247 They are now passed through (except when using the C API function
2248 ``PyDict_GetItem()``, whose semantics did not change).
2249
2250- Bug #1456209: In some obscure cases it was possible for a class with a
2251 custom ``__eq__()`` method to confuse dict internals when class instances
2252 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
2253 No, you don't have any code that did this ;-)

2256-----------------
2257
Trent Mick960a3f82006-06-28 20:30:41 +00002258- Bug #1295808: expat symbols should be namespaced in pyexpat
2259
2260- Patch #1462338: Upgrade pyexpat to expat 2.0.0
2261
Brett Cannon6ee7d012006-06-08 16:23:04 +00002262- Change binascii.hexlify to accept a read-only buffer instead of only a char
2263 buffer and actually follow its documentation.
2264
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00002265- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
2266
Nick Coghlanc649ec52006-05-29 12:43:05 +00002267- Patch #1478788 (modified version): The functional extension module has
2268 been renamed to _functools and a functools Python wrapper module added.
2269 This provides a home for additional function related utilities that are
2270 not specifically about functional programming. See PEP 309.
2271
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00002272- Patch #1493701: performance enhancements for struct module.

2275
Georg Brandl8d3342b2006-05-16 07:38:27 +00002276- Patch #1435422: zlib's compress and decompress objects now have a
2277 copy() method.
2278
Andrew MacIntyre92913322006-06-13 15:04:24 +00002279- Patch #1454481: thread stack size is now tunable at runtime for thread
2280 enabled builds on Windows and systems with Posix threads support.
2281
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002282- On Win32, os.listdir now supports arbitrarily-long Unicode path names
2283 (up to the system limit of 32K characters).
2284
2285- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
2286 As a result, these functions now raise WindowsError instead of OSError.
2287
Tim Peters7a822da2006-05-25 21:50:17 +00002288- ``time.clock()`` on Win64 should use the high-performance Windows
2289 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
2290 Windows platforms).
2291
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002292- Calling Tk_Init twice is refused if the first call failed as that
2293 may deadlock.
2294
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00002295- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
2296 accept it without potentially using an uninitialized pointer.

Gregory P. Smith372b5832006-06-05 18:48:21 +00002305- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
2306 parameter is supplied. [SF pybsddb bug #1477863]
2307
Gregory P. Smith3c228b12006-06-05 23:59:37 +00002308- bsddb: the __len__ method of a DB object has been fixed to return correct
2309 results. It could previously incorrectly return 0 in some cases.
2310 Fixes SF bug 1493322 (pybsddb bug 1184012).
2311
Gregory P. Smithff7d9912006-06-08 05:17:08 +00002312- bsddb: the bsddb.dbtables Modify method now raises the proper error and
2313 aborts the db transaction safely when a modifier callback fails.
2314 Fixes SF python patch/bug #1408584.
2315
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002316- bsddb: multithreaded DB access using the simple bsddb module interface

2350
Tim Peters43898b42006-06-14 04:09:25 +00002351- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2352 guarantee that adjacent triples in the return list always describe
2353 non-adjacent blocks. Previously, a pair of matching blocks could end
2354 up being described by multiple adjacent triples that formed a partition
2355 of the matching pair.

2364
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002365- The wsgiref package has been added to the standard library.
2366
Nick Coghlan676725d2006-06-08 13:54:49 +00002367- The functions update_wrapper() and wraps() have been added to the functools
2368 module. These make it easier to copy relevant metadata from the original
2369 function when writing wrapper functions.
2370
Tim Petersd6a9eef2006-06-05 01:48:21 +00002371- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2372 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.

Martin v. Löwis3f767792006-06-04 19:36:28 +00002374- Patch #1359618: Speed up charmap encoder by using a trie structure
2375 for lookup.
2376
Tim Petersd609b1a2006-06-02 23:22:51 +00002377- The functions in the ``pprint`` module now sort dictionaries by key
2378 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2379 if and only if its display required more than one line, although that
2380 wasn't documented. The new behavior increases predictability; e.g.,
2381 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.

Georg Brandlb89316f2006-05-17 15:51:16 +00002393- Patch #1180296: Two new functions were added to the locale module:
2394 format_string() to get the effect of "format % items" but locale-aware,
2395 and currency() to format a monetary number with currency sign.

2402
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002403- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2404 stdout arguments, making it possible to redirect input and output
2405 for remote debugging.
2406
2407- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2408 a couple of issues, notably handling of long file names using the
2409 GNU LONGNAME extension.
2410
2411- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2412 new flag when ``name`` is already the name of an option flag.
2413
2414- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2415 package.

2459-----------------
2460
Thomas Heller1b046642006-04-18 18:51:06 +00002461- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2462 by converting these apis from macros into exported functions again:
2463
2464 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2465 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2466 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2467 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2468 PyRun_String Py_CompileString
2469
Martin v. Löwis45294a92006-04-18 06:24:08 +00002470- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2471
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002472- All uses of PyStructSequence_InitType have been changed to initialize
2473 the type objects only once, even if the interpreter is initialized
2474 multiple times.
2475
Neal Norwitz61546162006-04-14 05:20:28 +00002476- Bug #1454485, array.array('u') could crash the interpreter. This was
2477 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2478 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2479
2480- Py_UNICODE is unsigned. It was always documented as unsigned, but
2481 due to a bug had a signed value in previous versions.
2482
Tim Peters3a5e8b12006-04-11 01:44:07 +00002483- Patch #837242: ``id()`` of any Python object always gives a positive
2484 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2485 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002486 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002487 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002488
Tim Peters3a5e8b12006-04-11 01:44:07 +00002489 def __hash__(self):
2490 return id(self) # WRONG
2491
2492 because a hash result must be a (short) Python int but it was always
2493 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002494 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002495 was always usable as a hash value before this patch. That's no longer
2496 necessarily so.
2497
2498- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002499 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002500 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002501 #1454844)
2502
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002503- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2504 involving generators that have paused outside of any ``try`` or ``with``
2505 blocks. (In 2.5a1, a paused generator that was part of a reference
2506 cycle could not be garbage collected, regardless of whether it was
2507 paused in a ``try`` or ``with`` block.)

Tim Peters711bf302006-04-25 03:31:36 +00002539- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes

2541 or exception is ignored).
2542
Nick Coghlanda2268f2006-04-24 04:37:15 +00002543- Fixed contextlib.nested to cope with exceptions being raised and
2544 caught inside exit handlers.
2545
Greg Wardab05edc2006-04-23 03:47:58 +00002546- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2547 hex, octal, or binary; add ``append_const`` action; keep going if
2548 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2549 added ``epilog`` for better help generation).
2550
Tim Peters21fbd572006-04-21 21:18:10 +00002551- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2552 called from a thread spawned as a side effect of importing a module.
2553
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002554- The pydoc module now supports documenting packages contained in
2555 .zip or .egg files.
2556
2557- The pkgutil module now has several new utility functions, such
2558 as ``walk_packages()`` to support working with packages that are either
2559 in the filesystem or zip files.
2560
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002561- The mailbox module can now modify and delete messages from
2562 mailboxes, in addition to simply reading them. Thanks to Gregory
2563 K. Johnson for writing the code, and to the 2005 Google Summer of
2564 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002565
Tim Petersc7605f22006-04-17 21:12:33 +00002566- The ``__del__`` method of class ``local`` in module ``_threading_local``
2567 returned before accomplishing any of its intended cleanup.
2568
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002569- Patch #790710: Add breakpoint command lists in pdb.

Martin v. Löwis0f48d982006-04-14 14:34:26 +00002602- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2603 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002604 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002605 CXX from --with-cxx-main, see description in README.
2606
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002607- Patch #1429775: Link extension modules with the shared libpython.
2608
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002609- Fixed a libffi build problem on MIPS systems.
2610
Tim Peters8931ff12006-05-13 23:28:20 +00002611- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2612 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2613 and "%zu" for unsigned integers of type ``size_t``.
2614
Anthony Baxter51bcb682006-04-05 14:51:42 +00002615Tests
2616-----
2617
Nick Coghlanda2268f2006-04-24 04:37:15 +00002618- test_contextlib now checks contextlib.nested can cope with exceptions
2619 being raised and caught inside exit handlers.
2620
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002621- test_cmd_line now checks operation of the -m and -c command switches
2622
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002623- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2624 it separately and by hand. It also wasn't cleaning up its changes to
2625 the current Decimal context.
2626
Thomas Woutersabd08882006-04-26 15:53:30 +00002627- regrtest.py now has a -M option to run tests that test the new limits of
2628 containers, on 64-bit architectures. Running these tests is only sensible
2629 on 64-bit machines with more than two gigabytes of memory. The argument
2630 passed is the maximum amount of memory for the tests to use.
2631
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00002632Tools

2634
2635- Added the Python benchmark suite pybench to the Tools/ directory;
2636 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002638Documentation
2639-------------
2640
Tim Petersb06d28c2006-05-12 01:57:59 +00002641- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2642
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002643- PEP 343: Added Context Types section to the library reference
2644 and attempted to bring other PEP 343 related documentation into
2645 line with the implementation and/or python-dev discussions.
2646
Tim Peters8dc73d22006-04-24 02:03:16 +00002647- Bug #1337990: clarified that ``doctest`` does not support examples
2648 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002651What's New in Python 2.5 alpha 1?
2652=================================
2653
Anthony Baxterebed3f62006-04-03 15:03:44 +00002654*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002655
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002656Core and builtins
2657-----------------
2658
Nick Coghlan43832302006-04-23 17:04:07 +00002659- PEP 338: -m command line switch now delegates to runpy.run_module
2660 allowing it to support modules in packages and zipfiles
2661
Martin v. Löwisc661b882006-04-20 04:54:23 +00002662- On Windows, .DLL is not an accepted file name extension for
2663 extension modules anymore; extensions are only found if they
2664 end in .PYD.
2665
Martin v. Löwisea62d252006-04-03 10:56:49 +00002666- Bug #1421664: sys.stderr.encoding is now set to the same value as
2667 sys.stdout.encoding.
2668
Neal Norwitz92e212f2006-04-03 04:48:37 +00002669- __import__ accepts keyword arguments.
2670
Georg Brandlccadf842006-03-31 18:54:53 +00002671- Patch #1460496: round() now accepts keyword arguments.
2672
Anthony Baxter262c00a2006-03-30 10:53:17 +00002673- Fixed bug #1459029 - unicode reprs were double-escaped.
2674
Hye-Shik Changd478f342006-03-23 12:32:36 +00002675- Patch #1396919: The system scope threads are reenabled on FreeBSD
2676 5.4 and later versions.
2677
Neal Norwitze98ccf62006-03-23 05:39:47 +00002678- Bug #1115379: Compiling a Unicode string with an encoding declaration
2679 now gives a SyntaxError.
2680
Georg Brandlabd1ff82006-03-18 07:59:59 +00002681- Previously, Python code had no easy way to access the contents of a
2682 cell object. Now, a ``cell_contents`` attribute has been added
2683 (closes patch #1170323).
2684
Tim Peterscf79aac2006-03-16 01:14:46 +00002685- Patch #1123430: Python's small-object allocator now returns an arena to
2686 the system ``free()`` when all memory within an arena becomes unused
2687 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2688 freed. Some applications will see a drop in virtual memory size now,
2689 especially long-running applications that, from time to time, temporarily
2690 use a large number of small objects. Note that when Python returns an
2691 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002692 platform C library will in turn return that memory to the operating system.
2693 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002694 appears to be effective at least on Microsoft C and gcc-based systems.
2695 Thanks to Evan Jones for hard work and patience.
2696
Georg Brandl533ff6f2006-03-08 18:09:27 +00002697- Patch #1434038: property() now uses the getter's docstring if there is
2698 no "doc" argument given. This makes it possible to legitimately use
2699 property() as a decorator to produce a read-only property.
2700
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002701- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2702 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2703 of requiring an int or long in slicing and a few other contexts, enabling
2704 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2705
Neal Norwitz995acdf2006-03-07 05:01:00 +00002706- Fixed various bugs reported by Coverity's Prevent tool.
2707
Brett Cannonbf364092006-03-01 04:25:17 +00002708- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2709 new exception base class, BaseException, which has a new message attribute.
2710 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2711 Raising a string exception now raises a DeprecationWarning.
2712
Thomas Woutersfb609f42006-02-28 16:37:25 +00002713- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2714 explicitly relative, using 'from .module import name' to mean 'from the same
2715 package as this module is in. Imports without dots still default to the
2716 old relative-then-absolute, unless 'from __future__ import
2717 absolute_import' is used.
2718
Brett Cannona7446e32006-02-27 23:39:10 +00002719- Properly check if 'warnings' raises an exception (usually when a filter set
2720 to "error" is triggered) when raising a warning for raising string
2721 exceptions.
2722
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002723- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002724 The name was removed from Include/code.h.
2725
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002726- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002727
Guido van Rossum1968ad32006-02-25 22:38:04 +00002728- Patch 1433928:
2729 - The copy module now "copies" function objects (as atomic objects).
2730 - dict.__getitem__ now looks for a __missing__ hook before raising
2731 KeyError.
2732
Tim Peters84ef21c2006-02-28 20:39:06 +00002733- PEP 343: with statement implemented. Needs ``from __future__ import
2734 with_statement``. Use of 'with' as a variable will generate a warning.
2735 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002736 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002737 The following objects have __context__ methods:
2738 - The built-in file type.
2739 - The thread.LockType type.
2740 - The following types defined by the threading module:
2741 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2742 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002743
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002744- Fix the encodings package codec search function to only search
2745 inside its own package. Fixes problem reported in patch #1433198.
2746
2747 Note: Codec packages should implement and register their own
2748 codec search function. PEP 100 has the details.
2749
Tim Peters9ea89d22006-06-04 03:26:02 +00002750- PEP 353: Using ``Py_ssize_t`` as the index type.
2751
2752- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2753 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2754 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2755 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2756 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002757
Neal Norwitzfc76d632006-01-10 06:03:13 +00002758- Patch #1400181, fix unicode string formatting to not use the locale.
2759 This is how string objects work. u'%f' could use , instead of .
2760 for the decimal point. Now both strings and unicode always use periods.
2761
Neal Norwitz671b9e32006-01-09 07:07:12 +00002762- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2763 configure would break checking curses.h.
2764
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002765- Bug #959576: The pwd module is now builtin. This allows Python to be
2766 built on UNIX platforms without $HOME set.
2767
Neal Norwitzc10978f2005-12-19 06:07:16 +00002768- Bug #1072182, fix some potential problems if characters are signed.
2769
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002770- Bug #889500, fix line number on SyntaxWarning for global declarations.
2771
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002772- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2773
Neal Norwitze7214a12005-12-18 05:03:17 +00002774- Support for converting hex strings to floats no longer works.
2775 This was not portable. float('0x3') now raises a ValueError.
2776
Barry Warsaw2a38a862005-12-18 01:27:35 +00002777- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002778 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002779 is now displayed in interactive prompt banner.
2780
Georg Brandlfa166682005-12-17 21:45:17 +00002781- Implementation of PEP 341 - Unification of try/except and try/finally.
2782 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002783 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002784
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002785- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2786 now encodes backslash correctly.
2787
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002788- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2789
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002790- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002791 and long longs.
2792
Neal Norwitz67715f02005-11-09 06:59:35 +00002793- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002794 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002795 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002796
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002797- Replaced most Unicode charmap codecs with new ones using the
2798 new Unicode translate string feature in the builtin charmap
2799 codec; the codecs were created from the mapping tables available
2800 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2801 encodings now include a mapping for the Apple logo)
2802
Tim Peterse3547fd2005-12-16 23:13:57 +00002803- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002804
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002805- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002806
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002807- A new AST parser implementation was completed. The abstract
2808 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002809 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002810
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002811- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002812 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2813
Neal Norwitz708e51a2005-10-03 04:48:15 +00002814- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2815
Neal Norwitz11bd1192005-10-03 00:54:56 +00002816- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2817 Provide a warning when a directory is passed on the command line.
2818
Neal Norwitz40d37812005-10-02 01:48:49 +00002819- Fix segfault with invalid coding.
2820
2821- SF bug #772896: unknown encoding results in MemoryError.
2822
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002823- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002824 supported a __len__() method which evaluated to False when the iterator
2825 was empty.
2826
Guido van Rossum630db602005-09-20 18:49:54 +00002827- On 64-bit platforms, when __len__() returns a value that cannot be
2828 represented as a C int, raise OverflowError.
2829
Skip Montanarof8948ca2005-09-19 03:54:46 +00002830- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002831 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002832
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002833- SF bug #893549: parsing keyword arguments was broken with a few format
2834 codes.
2835
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002836- Changes donated by Elemental Security to make it work on AIX 5.3
2837 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2838 bug #105470: test_pwd fails on 64bit system (Opteron).
2839
Guido van Rossum539c6622005-09-14 17:49:54 +00002840- Changes donated by Elemental Security to make it work on HP-UX 11 on
2841 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2842
Georg Brandl4550b8d2005-08-26 06:43:52 +00002843- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002844 (fixes bug #1119418).
2845
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002846- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2847
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002848- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2849 exceptions that cause a function to exit.
2850
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002851- The implementation of set() and frozenset() was revised to use its
2852 own internal data structure. Memory consumption is reduced by 1/3
2853 and there are modest speed-ups as well. The API is unchanged.
2854
Tim Petersde7990b2005-07-17 23:45:23 +00002855- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2856
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002857- SF bug #1229429: PyObject_CallMethod failed to decrement some
2858 reference counts in some error exit cases.
2859
Tim Petersecc6e6a2005-07-10 22:30:55 +00002860- SF bug #1185883: Python's small-object memory allocator took over
2861 a block managed by the platform C library whenever a realloc specified
2862 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002863 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002864 portable way to copy data from the C-managed block into Python's
2865 small-object space without risking a memory fault. Python's small-object
2866 realloc now leaves such blocks under the control of the platform C

Michael W. Hudsonb8963812005-07-05 15:21:58 +00002869- SF bug #1232517: An overflow error was not detected properly when
2870 attempting to convert a large float to an int in os.utime().
2871
Raymond Hettinger3296e692005-06-29 23:29:56 +00002872- SF bug #1224347: hex longs now print with lowercase letters just
2873 like their int counterparts.
2874
Michael W. Hudson188d4362005-06-20 16:52:57 +00002875- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2876 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2877 interpreter states; back out that fix and do a better job (see
2878 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2879 for a longer write-up of the problem).
2880
Michael W. Hudsondf888462005-06-03 14:41:55 +00002881- SF patch #1180995: marshal now uses a binary format by default when
2882 serializing floats.
2883
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002884- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2885 the routines that promise to produce IEEE 754 binary representations
2886 of floats now simply copy bytes around.
2887
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002888- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2889 278.
2890
Brett Cannonc3647ac2005-04-26 03:45:26 +00002891- patch #1109424: int, long, float, complex, and unicode now check for the
2892 proper magic slot for type conversions when subclassed. Previously the
2893 magic slot was ignored during conversion. Semantics now match the way
2894 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002895 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002896 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002897 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002898
Barry Warsawc8d907c2005-04-19 23:43:40 +00002899- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2900 NULL, now raise an AttributeError when attempting to set or delete the
2901 attribute. Previously a TypeError was raised, but this was inconsistent
2902 with the equivalent pure-Python implementation.
2903
Michael W. Hudson774479c2005-04-18 08:46:17 +00002904- It is now safe to call PyGILState_Release() before
2905 PyEval_InitThreads() (note that if there is reason to believe there
2906 are multiple threads around you still must call PyEval_InitThreads()
2907 before using the Python API; this fix is for extension modules that
2908 have no way of knowing if Python is multi-threaded yet).
2909
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002910- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2911 disabled caused a crash.
2912
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002913- Bug #1165306: instancemethod_new allowed the creation of a method
2914 with im_class == im_self == NULL, which caused a crash when called.
2915
Tim Petersecc6e6a2005-07-10 22:30:55 +00002916- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002917 fixes the crash seen in bug #1165761
2918
Raymond Hettinger96229b12005-03-11 06:49:40 +00002919- Added two new builtins, any() and all().
2920
Brett Cannon409d8f22005-03-05 06:47:57 +00002921- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002922 (e.g., ``class C(): pass`` is no longer a syntax error).
2923 Patch #1176012 added support to the 'parser' module and 'compiler' package
2924 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002925
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002926- Patch #1115086: Support PY_LONGLONG in structmember.
2927
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002928- Bug #1155938: new style classes did not check that __init__() was
2929 returning None.
2930
Tim Petersecc6e6a2005-07-10 22:30:55 +00002931- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002932 ('\') with a specific error message.
2933
Martin v. Löwisff232d72005-03-03 09:24:38 +00002934- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2935
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002936- Bug #1124295: the __name__ attribute of file objects was
2937 inadvertently made inaccessible in restricted mode.
2938
Tim Petersecc6e6a2005-07-10 22:30:55 +00002939- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002940 an ferror() call.
2941
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002942- min() and max() now support key= arguments with the same meaning as in
2943 list.sort().
2944
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002945- The peephole optimizer now performs simple constant folding in expressions:
2946 (2+3) --> (5).
2947
Raymond Hettingera422c342005-01-11 03:03:27 +00002948- set and frozenset objects can now be marshalled. SF #1098985.
2949
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002950- Bug #1077106: Poor argument checking could cause memory corruption
2951 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002952
Jeremy Hyltonab630502005-02-04 18:44:06 +00002953- The parser did not complain about future statements in illegal
2954 positions. It once again reports a syntax error if a future
2955 statement occurs after anything other than a doc string.
2956
Neil Schemenauercf52c072005-08-12 17:34:58 +00002957- Change the %s format specifier for str objects so that it returns a
2958 unicode instance if the argument is not an instance of basestring and
2959 calling __str__ on the argument returns a unicode instance.
2960
Tim Petersf4e69282006-02-27 17:15:31 +00002961- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2962 current thread state when the auto-GIL-state machinery knows about
2963 it (since the thread state is being deleted, continuing to remember it
2964 can't help, but can hurt if another thread happens to get created with
2965 the same thread id).
2966

2992
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002993- The unicodedata module was updated to the 4.1 version of the Unicode
2994 database. The 3.2 version is still available as unicodedata.db_3_2_0
2995 for applications that require this specific version (such as IDNA).
2996
Neal Norwitzb62c4332006-03-04 18:35:47 +00002997- The timing module is no longer built by default. It was deprecated

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003141- the cPickle module no longer accepts the deprecated None option in the
3142 args tuple returned by __reduce__().
3143
Raymond Hettingerb2594052004-12-05 09:25:51 +00003144- itertools.islice() now accepts None for the start and step arguments.
3145 This allows islice() to work more readily with slices:
3146 islice(s.start, s.stop, s.step)
3147
Skip Montanaro0af3ade2005-01-13 04:12:31 +00003148- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00003157- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
3158 been renamed to have only a single underscore prefix. This was done to
3159 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003160
Nick Coghlan43832302006-04-23 17:04:07 +00003161- PEP 338: new module runpy defines a run_module function to support
3162 executing modules which provide access to source code or a code object
3163 via the PEP 302 import mechanisms.
3164
Anthony Baxter93f5b932006-04-03 08:05:07 +00003165- The email module's parsedate_tz function now sets the daylight savings

3173 in attribute values.
3174
Anthony Baxterc51ee692006-04-01 00:57:31 +00003175- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00003176 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00003177 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00003178 module will not be built.
3179
Tim Petersc17976e2006-04-01 00:26:53 +00003180- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
3181 aren't officially supported here, and trying to use them will probably
3182 raise an exception some day. But dicts have been allowed, and "mostly
3183 worked", so support for them won't go away without warning.
3184
Georg Brandl338ef7d2006-03-31 18:42:16 +00003185- Bug #1445068: getpass.getpass() can now be given an explicit stream
3186 argument to specify where to write the prompt.
3187
Georg Brandl22ec80b2006-03-31 18:25:44 +00003188- Patch #1462313, bug #1443328: the pickle modules now can handle classes

3197 to make it easier to monitor when daemon threads have completed
3198 processing all enqueued tasks. Patch #1455676.
3199
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00003200- popen2.Popen objects now preserve the command in a .cmd attribute.

3203
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00003204- email 4.0 package now integrated. This is largely the same as the email 3.0
3205 package that was included in Python 2.3, except that PEP 8 module names are
3206 now used (e.g. mail.message instead of email.Message). The MIME classes
3207 have been moved to a subpackage (e.g. email.mime.text instead of
3208 email.MIMEText). The old names are still supported for now. Several
3209 deprecated Message methods have been removed and lots of bugs have been
3210 fixed. More details can be found in the email package documentation.
3211
Walter Dörwald40108c92006-03-27 08:15:44 +00003212- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
3213 (a subclass of tuple) that provides incremental decoders and encoders
3214 (a way to use stateful codecs without the stream API). Python functions
3215 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
3216 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
3217 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00003218
Walter Dörwald067db482006-03-15 22:17:27 +00003219- Patch #1359365: Calling next() on a closed StringIO.String object raises
3220 a ValueError instead of a StopIteration now (like file and cString.String do).
3221 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
3222 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00003223
Martin v. Löwis04824ce2006-03-10 21:26:16 +00003224- A regrtest option -w was added to re-run failed tests in verbose mode.

3297 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
3298 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
3299 Ronald L. Rivest offered this advice for Python:
3300
3301 "The consensus of researchers in this area (at least as
3302 expressed at the NIST Hash Function Workshop 10/31/05),
3303 is that SHA-256 is a good choice for the time being, but
3304 that research should continue, and other alternatives may
3305 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00003306
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00003307- Added a subset of Fredrik Lundh's ElementTree package. Available

3401
Raymond Hettinger68c04532005-06-10 11:05:19 +00003402- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00003403 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00003404 the generate_tokens() function now accepts a callable argument that
3405 terminates by raising StopIteration.

3411
Skip Montanaro174dd222005-05-14 20:54:16 +00003412- Patch #1120353: The xmlrpclib module provides better, more transparent,
3413 support for datetime.{datetime,date,time} objects. With use_datetime set
3414 to True, applications shouldn't have to fiddle with the DateTime wrapper
3415 class at all.
3416
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00003417- distutils.commands.upload was added to support uploading distribution
3418 files to PyPI.
3419
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00003420- distutils.commands.register now encodes the data as UTF-8 before posting
3421 them to PyPI.
3422
Raymond Hettinger267b8682005-03-27 10:47:39 +00003423- decimal operator and comparison methods now return NotImplemented
3424 instead of raising a TypeError when interacting with other types. This
3425 allows other classes to implement __radd__ style methods and have them
3426 work as expected.
3427
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003428- Bug #1163325: Decimal infinities failed to hash. Attempting to

3465
Guido van Rossumd0641422005-02-03 15:01:24 +00003466- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3467 disables recursive traversal through instance attributes, which can
3468 be exploited in various ways.
3469
Tim Peterse3547fd2005-12-16 23:13:57 +00003470- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003471 flags on the HTTP listening socket.
3472
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003473- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3474 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3475
Fred Drakefbdeaad2006-07-29 16:56:15 +00003476- Patches #893642, #1039083: add allow_none, encoding arguments to

3482
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003483- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3484
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003485- Enhancements to the csv module:
3486
3487 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003488 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003489 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003490 + Dialect parameter parsing has been re-implemented to improve error
3491 reporting.
3492 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3493 dictates.
3494 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003495 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003496 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003497 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3498 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003499 + reader now allows \r characters to be quoted (previously it only allowed
3500 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003501 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003502 + Dialect classes passed to the module are no longer instantiated by
3503 the module before being parsed (the former validation scheme required
3504 this, but the mechanism was unreliable).
3505 + The dialect registry now contains instances of the internal
3506 C-coded dialect type, rather than references to python objects.
3507 + the internal c-coded dialect type is now immutable.
3508 + register_dialect now accepts the same keyword dialect specifications
3509 as the reader and writer, allowing the user to register dialects
3510 without first creating a dialect class.
3511 + a configurable limit to the size of parsed fields has been added -
3512 previously, an unmatched quote character could result in the entire
3513 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003514 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003515 the parser field size limit (returning the former limit). The initial
3516 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003517 + A line_num attribute has been added to the reader object, which tracks
3518 the number of lines read from the source iterator. This is not
3519 the same as the number of records returned, as records can span
3520 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003521 + reader and writer objects were not being registered with the cyclic-GC.
3522 This has been fixed.
3523
Brett Cannone6539c42005-01-08 02:43:53 +00003524- _DummyThread objects in the threading module now delete self.__block that is
3525 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3526 lock primitives tend to be limited in number and thus should not be wasted on
3527 a _DummyThread object. Fixes bug #1089632.
3528
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003529- The imghdr module now detects Exif files.
3530
Raymond Hettinger6065d322004-12-20 23:51:53 +00003531- StringIO.truncate() now correctly adjusts the size attribute.
3532 (Bug #951915).
3533
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003534- locale.py now uses an updated locale alias table (built using
3535 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3536 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003537 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003538
Raymond Hettinger3557f422004-12-07 12:02:02 +00003539- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3540
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003541- the pickle module no longer accepts the deprecated None option in the
3542 args tuple returned by __reduce__().
3543
Brett Cannon84667c02004-12-07 03:25:18 +00003544- optparse now optionally imports gettext. This allows its use in setup.py.
3545
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003546- the pickle module no longer uses the deprecated bin parameter.
3547
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003548- the shelve module no longer uses the deprecated binary parameter.
3549
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003550- the pstats module no longer uses the deprecated ignore() method.
3551
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003552- the filecmp module no longer uses the deprecated use_statcache argument.
3553
Raymond Hettinger664347b2004-12-04 21:21:53 +00003554- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3555 extended or overridden by subclasses. Formerly, the subclassed method would
3556 be ignored by the rest of the module. (Bug #1078905).
3557
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003558- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003559 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003560
Walter Dörwald36733692004-12-22 12:50:50 +00003561- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3562 once when a size argument is given. This prevents a buffer overflow in the
3563 tokenizer with very long source lines.
3564
Barry Warsaw538561e2006-01-01 21:48:54 +00003565- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3566 immediately after creating the object, without any intervening
3567 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003568
Skip Montanaro05885812005-01-16 20:48:27 +00003569- The reconvert.quote function can now emit triple-quoted strings. The
3570 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003571
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003572- ``UserString.MutableString`` now supports negative indices in
3573 ``__setitem__`` and ``__delitem__``
3574
Greg Ward40407942005-03-05 02:53:17 +00003575- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3576 correctly.
3577
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003578- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3579 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3580 character even if the user has passed a size parameter to get a proper
3581 line ending. Remove the special handling of a "\r\n" that has been split
3582 between two lines.
3583
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003584- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3585 about illegal code points. The codec now supports PEP 293 style error
3586 handlers.
3587
Walter Dörwald78a78b02005-09-01 12:04:29 +00003588- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003589 from the input stream, so that the output is a byte string in the correct
3590 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003591
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003592- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3593 considering it exactly like a '*'.
3594
Walter Dörwald007f8df2005-10-09 19:42:27 +00003595- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3596 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003597
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003598- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3599
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003600- Patch #1413711: Certain patterns of differences were making difflib
3601 touch the recursion limit.
3602
Walter Dörwald58917a62006-03-31 15:26:22 +00003603- Bug #947906: An object oriented interface has been added to the calendar
3604 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003605 called as a script (e.g. via ``python -mcalendar``). Localized month and
3606 weekday names can be ouput (even if an exotic encoding is used) using
3607 special classes that use unicode.

3618
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003619- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3620
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003621- Patch #881820: look for openpty and forkpty also in libbsd.
3622
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003623- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3624 The zlib module is now builtin on Windows.
3625
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003626- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3627
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003628- Bug #1189330: configure did not correctly determine the necessary
3629 value of LINKCC if python was built with GCC 4.0.
3630
Trent Mick8321b422005-07-26 02:29:21 +00003631- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3632 vulnerability in zlib 1.2.1 and 1.2.2.
3633
Brett Cannon08cd5982005-04-24 22:26:38 +00003634- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3635 flags that change binary compatibility. Changes were also made to
3636 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003637 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003638
Bob Ippolitoed233462005-03-29 13:47:59 +00003639- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3640 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3641 no longer exists). This configure patch makes things right.
3642
Martin v. Löwise2713be2005-03-08 15:03:08 +00003643- Bug #1158607: Build with --disable-unicode again.
3644
Brett Cannon46d96232005-02-16 00:07:19 +00003645- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3646 defined. Discovered as a result of not being able to build on OS X.
3647
Brett Cannon516592f2004-12-07 00:42:59 +00003648- setup.py now uses the directories specified in LDFLAGS using the -L option
3649 and in CPPFLAGS using the -I option for adding library and include
3650 directories, respectively, for compiling extension modules against. This has
3651 led to the core being compiled using the values in CPPFLAGS. It also removes
3652 the need for the special-casing of both DarwinPorts and Fink for darwin since
3653 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3654 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3655 Fink, ``-I/opt/local/include`` for DarwinPorts).
3656
Brett Cannon43802422005-02-10 20:48:03 +00003657- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3658 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3659 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.

Tim Petersc9d78aa2006-03-26 23:27:58 +00003665- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3666 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3667 is obtained via the ``PyObject_`` family, it must be released via the
3668 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3669 always been officially true, but when Python's small-object allocator was
3670 introduced, an attempt was made to cater to a few extension modules
3671 discovered at the time that obtained memory via ``PyObject_New`` but
3672 released it via ``PyMem_DEL``. It's years later, and if such code still
3673 exists it will fail now (probably with segfaults, but calling wrong
3674 low-level memory management functions can yield many symptoms).
3675
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003676- Added a C API for set and frozenset objects.
3677

3679
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003680- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3681 mapping argument now. This string is used as a mapping table. Byte values
3682 greater than the length of the string and 0xFFFE are treated as undefined
3683 mappings.
