Neal Norwitz92422fb2006-08-18 03:57:54 +000011
12Core and builtins
13-----------------
14
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +000015- Issue #2045: Fix an infinite recursion triggered when printing a subclass of
16 collections.defaultdict, if its default_factory is set to a bound method.
17
Christian Heimesf75dbef2008-02-08 00:11:31 +000018- Fixed a minor memory leak in dictobject.c. The content of the free
19 list was not freed on interpreter shutdown.
20
Christian Heimes6075a822008-02-06 12:44:34 +000021- Limit free list of method and builtin function objects to 256 entries
22 each.
23
Amaury Forgeot d'Arc578a8ca2008-02-04 20:53:14 +000024- Patch #1953: Added ``sys._compact_freelists()`` and the C API functions
25 ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +000026 to compact the internal free lists of pre-allocted ints and floats.
27
Christian Heimes951cc0f2008-01-31 23:08:23 +000028- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
29 Python expected the return type int but the fork familie returns pi_t.
30
Mark Dickinson105be772008-01-31 22:17:37 +000031- Issue #1678380: Fix a bug that identifies 0j and -0j when they appear
32 in the same code unit.
33
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +000034- Issue #2025 : Add tuple.count() and tuple.index() methods to comply with
35 the collections.Sequence API.
36
Christian Heimes4d4f2702008-01-30 11:32:37 +000037- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and linebreak
38 detection
39
Christian Heimes422051a2008-02-04 18:00:12 +000040- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear the
Christian Heimes908caac2008-01-27 23:34:59 +000041 internal lookup cache for ref leak tests.
42
Georg Brandl0cdf9a32008-01-26 14:14:20 +000043- Patch #1473257: generator objects gain a gi_code attribute. This is the
44 same object as the func_code attribute of the function that produced the
45 generator.
46
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +000047- Issue #1920: "while 0" statements were completely removed by the compiler,
48 even in the presence of an "else" clause, which is supposed to be run when
49 the condition is false. Now the compiler correctly emits bytecode for the
50 "else" suite.
51
Guido van Rossumeead05f2008-01-24 18:21:02 +000052- A few crashers fixed: weakref_in_del.py (issue #1377858);
53 loosing_dict_ref.py (issue #1303614, test67.py);
54 borrowed_ref_[34].py (not in tracker).
55
Vinay Sajipd7cf32e2008-01-24 12:43:33 +000056- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +000057 suppressed while an extension is loaded by calling SetErrorMode in
58 dynload_win.c. The error is still reported properly.
59
Christian Heimes082c9b02008-01-23 14:20:50 +000060- Bug #1915: Python compiles with --enable-unicode=no again. However
61 several extension methods and modules do not work without unicode
62 support.
63
Georg Brandl26543b12008-01-21 18:36:51 +000064- Issue #1882: when compiling code from a string, encoding cookies in the
65 second line of code were not always recognized correctly.
66
Georg Brandl14404b62008-01-19 19:27:05 +000067- Issue #1679: "0x" was taken as a valid integer literal.
68
Georg Brandl6caad7d2008-01-26 14:19:22 +000069- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +000070 added.
71
Christian Heimesc94e2b52008-01-14 04:13:37 +000072- sys.float_info / PyFloat_GetInfo: The floating point information
73 object was converted from a dict to a specialized structseq object.
74
Christian Heimesf31b69f2008-01-14 03:42:48 +000075- Patch #1816: Added sys.flags structseq. It exposes the status of most
Vinay Sajip2bdc48c2008-01-21 18:16:05 +000076 command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +000077
Georg Brandl6caad7d2008-01-26 14:19:22 +000078- Objects/structseq.c: Implemented new structseq representation. The patch
Christian Heimesf31b69f2008-01-14 03:42:48 +000079 makes structseqs (e.g. the return value of os.stat) more readable.
Christian Heimes9c201962008-01-14 03:33:52 +000080
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +000081- Patch #1700288: added a type attribute cache that caches method accesses,
82 resulting in speedups in heavily object-oriented code.
83
Neal Norwitz3fc15b82008-01-10 05:42:58 +000084- Bug #1776: __import__() no longer accepts filenames on any platform.
85 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +000086
Georg Brandlaed6c662008-01-07 17:25:53 +000087- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
88
Georg Brandl2da0fce2008-01-07 17:09:35 +000089- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE envvar
90 and sys.dont_write_bytecode attribute. All these can be set to forbid Python
91 to attempt to write compiled bytecode files.
92
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +000093- Improve some exception messages when Windows fails to load an extension
94 module. Now we get for example '%1 is not a valid Win32 application' instead
95 of 'error code 193'.
96
Christian Heimes8267d1d2008-01-04 00:37:34 +000097- Bug #1481296: Fixed long(float('nan'))!=0L.
98
Christian Heimeseebb79c2008-01-03 22:32:26 +000099- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x, y)
100 functions.
Christian Heimese2ca4242008-01-03 20:23:15 +0000101
Christian Heimes0a8143f2007-12-18 23:22:54 +0000102- Issue #1635: Platform independent creation and representation of NaN
103 and INF. float("nan"), float("inf") and float("-inf") now work on every
104 platform with IEEE 754 semantics.
105
Raymond Hettingerfd7ed402007-12-18 21:24:09 +0000106- Compiler now generates simpler and faster code for dictionary literals.
107 The oparg for BUILD_MAP now indicates an estimated dictionary size.
108 There is a new opcode, STORE_MAP, for adding entries to the dictionary.
109
Christian Heimesdb3d6cb2007-12-16 21:39:43 +0000110- Issue #1638: %zd configure test fails on Linux
111
Christian Heimes90e10e72007-12-14 02:35:23 +0000112- Issue #1620: New property decorator syntax was modifying the decorator
113 in place instead of creating a new decorator object.
114
Christian Heimes284d9272007-12-10 22:28:56 +0000115- Issue #1580: New free format floating point representation based on
116 "Floating-Point Printer Sample Code", by Robert G. Burger. For example
117 repr(11./5) now returns '2.2' instead of '2.2000000000000002'.
118
Skip Montanaro26015492007-12-08 15:33:24 +0000119- Issue #1538: Avoid copying string in split/rsplit if the split
120 char is not found.
121
Andrew M. Kuchling395fe442007-12-05 13:27:20 +0000122- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +0000123 SystemError.
124
Nick Coghlanef01d822007-12-03 12:55:17 +0000125- PEP 366: Allow explicit relative imports when executing modules
126 inside packages with the -m switch via a new module level
127 __package__ attribute.
128
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +0000129- Issue #1402: Fix a crash on exit, when another thread is still running, and
130 if the deallocation of its frames somehow calls the PyGILState_Ensure() /
131 PyGILState_Release() functions.
132
Christian Heimes28104c52007-11-27 23:16:44 +0000133- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
134
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000135- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +0000136 attribute of an empty cell object.
137
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +0000138- Issue #1460: The utf-7 incremental decoder did not accept truncated input.
139 It now correctly saves its state between chunks of data.
140
Nick Coghlan327a39b2007-11-18 11:56:28 +0000141- Patch #1739468: Directories and zipfiles containing a __main__.py file can
142 now be directly executed by passing their name to the interpreter. The
143 directory/zipfile is automatically inserted as the first entry in sys.path.
144
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +0000145- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
146 generator expression when at the same time the executed code is closing a
147 paused generator.
148
Raymond Hettinger1760c8a2007-11-08 02:52:43 +0000149- sets and frozensets now have an isdisjoint() method.
150
Raymond Hettinger3f8caa32007-10-24 01:28:33 +0000151- optimize the performance of builtin.sum().
152
Neal Norwitz44f326e2007-10-05 05:29:17 +0000153- Fix warnings found by the new version of the Coverity checker.
154
Raymond Hettinger8f669372007-10-03 21:18:11 +0000155- The enumerate() builtin function is no longer bounded to sequences smaller
156 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
157 shifts from ints to longs.
158
Brett Cannon0b14f242007-09-30 19:45:10 +0000159- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
160 having a self-referential tuple, which is possible from C code. Nor did
161 object's tp_str consider that a type's tp_str could do something that could
162 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
163 respectively, fixed the issues.
164
Brett Cannon01531592007-09-17 03:28:34 +0000165- Issue #1164: It was possible to trigger deadlock when using the 'print'
166 statement to write to a file since the GIL was not released as needed. Now
167 PyObject_Print() does the right thing along with various tp_print
168 implementations of the built-in types and those in the collections module.
169
Brett Cannon4c20bc42007-09-11 21:02:28 +0000170- Issue #1147: Exceptions were directly allowing string exceptions in their
171 throw() method even though string exceptions no longer allowed.
172
Brett Cannona0c05512007-09-10 21:38:27 +0000173- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
174 list by using the recursion counter.
175
Brett Cannon1e534b52007-09-07 04:18:30 +0000176- Issue #1202533: Fix infinite recursion calls triggered by calls to
177 PyObject_Call() never calling back out to Python code to trigger recursion
178 depth updates/checks. Required the creation of a static RuntimeError
179 instance in case normalizing an exception put the recursion check value past
180 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
181
Martin v. Löwisa5136192007-09-04 14:19:28 +0000182- Patch #1031213: Decode source line in SyntaxErrors back to its original source
183 encoding.
184
Georg Brandl7c3b50d2007-07-12 08:38:00 +0000185- Patch #1673759: add a missing overflow check when formatting floats
186 with %G.
187
Neal Norwitzdb2b1b32007-06-11 07:36:24 +0000188- Prevent expandtabs() on string and unicode objects from causing a segfault
189 when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +0000190
Martin v. Löwisda587ab2007-06-08 17:29:20 +0000191- Bug #1733488: Fix compilation of bufferobject.c on AIX.
192
Georg Brandl25497a12007-06-01 19:20:27 +0000193- Bug #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +0000194
Neal Norwitz0ac60192007-05-27 04:08:54 +0000195- Add new attribute names for function objects. All the func_* become
196 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
197
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +0000198- Add -3 option to the interpreter to warn about features that are
199 deprecated and will be changed/removed in Python 3.0.
200
Georg Brandl2134e752007-05-21 20:34:16 +0000201- Patch #1686487: you can now pass any mapping after '**' in function
202 calls.
203
Collin Winter62903052007-05-18 23:11:24 +0000204- except clauses may now be spelled either "except E, target:" or
205 "except E as target:". This is to provide forwards compatibility with
206 Python 3.0.
207
Brett Cannon229cee22007-05-05 01:34:02 +0000208- Deprecate BaseException.message as per PEP 352.
209
Armin Rigo9790a272007-05-02 19:23:31 +0000210- Bug #1303614: don't expose object's __dict__ when the dict is
211 inherited from a builtin base.
212
Vinay Sajip8549ce32007-05-06 17:53:37 +0000213- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +0000214 setting a plain string, ie don't expand to single letter identifiers.
215
Raymond Hettinger13936692007-04-11 18:40:58 +0000216- Request #1191699: Slices can now be pickled.
217
Raymond Hettinger4db5fe92007-04-12 04:10:00 +0000218- Request #1193128: str.translate() now allows a None argument for
219 translations that only remove characters without re-mapping the
220 remaining characters.
221
Georg Brandl5cb76c12007-03-21 09:00:39 +0000222- Patch #1682205: a TypeError while unpacking an iterable is no longer
223 masked by a generic one with the message "unpack non-sequence".
224
Neal Norwitzaa754b72007-03-21 06:39:48 +0000225- Remove unused file Python/fmod.c.
226
Guido van Rossum143b5642007-03-23 04:58:42 +0000227- Bug #1683368: The object.__init__() and object.__new__() methods are
228 now stricter in rejecting excess arguments. The only time when
229 either allows excess arguments is when it is not overridden and the
230 other one is. For backwards compatibility, when both are
231 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +0000232 warning later). Also, type.__init__() insists on the same signature
233 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +0000234
Georg Brandl2b869942007-03-17 16:08:45 +0000235- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
236 to complex using its __complex__() method before falling back to the
237 __float__() method. Therefore, the functions in the cmath module now
238 can operate on objects that define a __complex__() method.
239
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +0000240- Patch #1623563: allow __class__ assignment for classes with __slots__.
241 The old and the new class are still required to have the same slot names.
242
Collin Winter77c67bd2007-03-16 04:11:30 +0000243- Patch #1642547: Fix an error/crash when encountering syntax errors in
244 complex if statements.
245
Žiga Seilnacht20f43d32007-03-15 11:44:55 +0000246- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
247 is called with an object that is faking its type.
248
Žiga Seilnacht71436f02007-03-14 12:24:09 +0000249- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
250 name.
251
Georg Brandl5240d742007-03-13 20:46:32 +0000252- Patch #1444529: the builtin compile() now accepts keyword arguments.
253
Georg Brandl7b9c5552007-03-12 14:30:05 +0000254- Bug #1678647: write a newline after printing an exception in any
255 case, even when converting the value to a string failed.
256
Georg Brandl871f1bc2007-03-12 13:17:36 +0000257- The dir() function has been extended to call the __dir__() method on
258 its argument, if it exists. If not, it will work like before. This allows
259 customizing the output of dir() in the presence of a __getattr__().
260
Collin Winter276887b2007-03-12 16:11:39 +0000261- Patch #922167: Python no longer segfaults when faced with infinitely
262 self-recursive reload() calls (as reported by bug #742342).
263
Žiga Seilnacht89032082007-03-11 15:54:54 +0000264- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
265
Collin Wintere38051d2007-03-09 20:33:07 +0000266- Patch #1491866: change the complex() constructor to allow parthensized
267 forms. This means complex(repr(x)) now works instead of raising a
268 ValueError.
269
Georg Brandlaa2321b2007-03-07 00:40:28 +0000270- Patch #703779: unset __file__ in __main__ after running a file. This
271 makes the filenames the warning module prints much more sensible when
272 a PYTHONSTARTUP file is used.
273
Georg Brandl49aafc92007-03-07 00:34:46 +0000274- Variant of patch #697613: don't exit the interpreter on a SystemExit
275 exception if the -i command line option or PYTHONINSPECT environment
276 variable is given, but break into the interactive interpreter just like
277 on other exceptions or normal program exit.
278
Georg Brandl00cd8182007-03-06 18:41:12 +0000279- Patch #1638879: don't accept strings with embedded NUL bytes in long().
280
Georg Brandl098cd692007-03-06 12:17:50 +0000281- Bug #1674503: close the file opened by execfile() in an error condition.
282
Georg Brandl0fca97a2007-03-05 22:28:08 +0000283- Patch #1674228: when assigning a slice (old-style), check for the
284 sq_ass_slice instead of the sq_slice slot.
285
Neal Norwitz88516a62007-02-26 22:41:45 +0000286- When printing an unraisable error, don't print exceptions. before the name.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00001189- pybsddb.sf.net Bug #477182: Load the database flags at database open
1190 time so that opening a database previously created with the DB_DUP or
1191 DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
1192 Specifically: dictionary assignment to a DB object will replace all
1193 values for a given key when the database allows duplicate values.
1194 DB users should use DB.put(k, v) when they want to store duplicates; not
1195 DB[k] = v.
1196

1428
Brett Cannon70c0c022008-02-03 09:59:21 +00001429- Have the search path for building extensions follow the declared order in
1430 $CPPFLAGS and $LDFLAGS when adding directories from those environment
1431 variables.
1432
Christian Heimes951cc0f2008-01-31 23:08:23 +00001433- Bug #1983: Added a check to pyport to verify that sizeof(pid_t) is
1434 smaller or equal sizeof(long).
1435

1439
1440- Removed PCbuild8/ directory and added a new build directory for VS 2005
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00001441 based on the VS 2008 build directory to PC/VS8.0. The script
Christian Heimes000a0742008-01-03 22:16:32 +00001442 PCbuild/vs8to9.py was added to sync changes from PCbuild to PC/VS8.0.
1443
1444- Moved PCbuild/ directory for VS 2003 to PC/VS7.1 and renamed PCBuild9/
1445 directory to PCBuild/.

1448
Guido van Rossum7c862f82007-12-13 20:50:10 +00001449- Bug #1608: use -fwrapv when GCC supports it. This is important,
1450 newer GCC versions may optimize away overflow buffer overflow checks
1451 without this option!
1452
Martin v. Löwis63bf1492007-11-12 05:14:05 +00001453- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.
1454
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00001455- Add a FAST_LOOPS build option that speeds-up looping by trading away
1456 periodic threadstate and signal checking in tight loops. By default,
1457 this option is turned-off. It should only be enabled in debugged,
1458 performance critical applications.
1459
Martin v. Löwisd44a4e92007-09-05 11:47:34 +00001460- Patch #786737: Allow building in a tree of symlinks pointing to

1470
Georg Brandldb846032007-03-31 18:56:11 +00001471- Bug #1655392: don't add -L/usr/lib/pythonX.Y/config to the LDFLAGS
1472 returned by python-config if Python was built with --enable-shared
1473 because that prevented the shared library from being used.
1474
Georg Brandl18c47f62007-03-13 10:19:22 +00001475- Patch #1569798: fix a bug in distutils when building Python from a
1476 directory within sys.exec_prefix.

1483 attribute.
1484
Vinay Sajip76fdb8c2006-12-14 08:53:55 +00001485- Bug #1578513: Cross compilation was broken by a change to configure.
Martin v. Löwisfefbc202006-10-17 18:59:23 +00001486 Repair so that it's back to how it was in 2.4.3.
1487
Martin v. Löwisc9e82f62006-10-15 07:54:40 +00001488- Patch #1576954: Update VC6 build directory; remove redundant

1502 to include some information about the build environment.
1503
Georg Brandl6caad7d2008-01-26 14:19:22 +00001504
Neal Norwitz92422fb2006-08-18 03:57:54 +00001505C API
1506-----
1507
Christian Heimes5b970ad2008-02-06 13:33:44 +00001508- Unified naming convention for free lists and their limits. All free lists
1509 in Object/ are named ``free_list``, the counter ``numfree`` and the upper
1510 limit is a macro ``PyName_MAXFREELIST`` inside an #ifndef block.
1511
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00001512- ``PySet_Add()`` can now modify a newly created frozenset. Similarly to
1513 ``PyTuple_SetItem``, it can be used to populate a brand new frozenset; but
1514 it does not steal a reference to the added item.
1515
1516- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
1517
Georg Brandl6caad7d2008-01-26 14:19:22 +00001518- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format and
1519 _FormatV from Python 3.0. Made PyLong_AsSsize_t and PyLong_FromSsize_t
1520 public functions.
1521
1522- Patch #1720595: add T_BOOL to the range of structmember types.
1523
1524- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
1525 ``PyFloat_GetInfo()`` to the float API.
1526
1527- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
1528 format code incorrectly truncated the length to an int, even when
1529 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
1530 results with huge strings.
1531
1532- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE
1533 and Py_REFCNT.
1534
1535- PEP 3123: Provide forward compatibility with Python 3.0, while keeping
1536 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
1537 PyVarObject_HEAD_INIT.
1538
1539- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
1540
1541- Patch #1733960: Allow T_LONGLONG to accept ints.
1542
1543- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
1544
Christian Heimes000a0742008-01-03 22:16:32 +00001545- Added a new API function ``PyImport_ImportModuleNoBlock``.
1546
Georg Brandl6caad7d2008-01-26 14:19:22 +00001547- Bug #1637022: Prefix AST symbols with _Py_.
1548
1549- Fix some leftovers from the conversion from int to Py_ssize_t
1550 (relevant to strings and sequences of more than 2**31 items).
1551
1552- Make _PyGILState_NoteThreadState() static, it was not used anywhere
1553 outside of pystate.c and should not be necessary.
1554
Christian Heimes000a0742008-01-03 22:16:32 +00001555- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do absolute
1556 imports. In earlier versions they might have used relative imports under
1557 some conditions.
1558
Andrew M. Kuchlingadc60ab2008-01-04 02:26:00 +00001559- Added case insensitive comparison methods ``PyOS_stricmp(char*, char*)``
Christian Heimes000a0742008-01-03 22:16:32 +00001560 and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
1561
Neal Norwitz8a267062006-08-19 04:25:29 +00001562- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx macro
1563 so it can be used as an expression.

1567-------
1568
Christian Heimes95d64472008-02-09 19:55:22 +00001569- Patch #1706: Drop support for Win9x, WinME and NT4. Python now requires
1570 Windows 2000 or greater. The _WINVER and NTDDI_VERSION macros are set to
1571 Win2k for x86/32bit builds and WinXP for AMD64 builds.
1572
Martin v. Löwis2607e6c2006-11-21 18:20:25 +00001573- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE
1574 and _CRT_NONSTDC_NO_DEPRECATE.
1575
Martin v. Löwisd476a402007-10-12 08:56:52 +00001576- Bug #1216: Restore support for Visual Studio 2002.

1583
Brett Cannon791d56f2007-05-31 19:40:42 +00001584- buildtools now raises a DeprecationWarning.
1585
Brett Cannon5e263512007-05-20 23:17:38 +00001586- Removed the macfs module. It had been deprecated since Python 2.5. This
1587 lead to the deprecation of macostools.touched() as it relied solely on macfs
1588 and was a no-op under OS X.

1597-----------------
1598
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001599- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001600 compared equal or unequal to a string and a UnicodeDecodeError
1601 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001602
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001603 Instead, the equal (==) and unequal (!=) comparison operators will
1604 now issue a UnicodeWarning and interpret the two objects as
1605 unequal. The UnicodeWarning can be filtered as desired using
1606 the warning framework, e.g. silenced completely, turned into an
1607 exception, logged, etc.
1608
1609 Note that compare operators other than equal and unequal will still
1610 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001611
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001612- Fix segfault when doing string formatting on subclasses of long.
1613
1614- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1615 with new-style classes.
1616
1617- Fix bug related to __len__ functions returning negative values with
1618 classic classes.
1619
1620- Patch #1538606, Fix __index__() clipping. There were some problems
1621 discovered with the API and how integers that didn't fit into Py_ssize_t
1622 were handled. This patch attempts to provide enough alternatives
1623 to effectively use __index__.
1624
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001625- Bug #1536021: __hash__ may now return long int; the final hash
1626 value is obtained by invoking hash on the long int.
1627
Thomas Hellerab1049c2006-08-08 17:37:00 +00001628- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1629
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001630- Bug #1535165: fixed a segfault in input() and raw_input() when
1631 sys.stdin is closed.
1632
Thomas Heller74d36f02006-08-04 18:17:40 +00001633- On Windows, the PyErr_Warn function is now exported from
1634 the Python dll again.
1635
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001636- Bug #1191458: tracing over for loops now produces a line event
1637 on each iteration. Fixing this problem required changing the .pyc
1638 magic number. This means that .pyc files generated before 2.5c1
1639 will be regenerated.
1640
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001641- Bug #1333982: string/number constants were inappropriately stored
1642 in the byte code and co_consts even if they were not used, ie
1643 immediately popped off the stack.
1644
Georg Brandle9462c72006-08-04 18:03:37 +00001645- Fixed a reference-counting problem in property().

1648Library
1649-------
1650
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001651- Fix a bug in the ``compiler`` package that caused invalid code to be
1652 generated for generator expressions.
1653
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001654- The distutils version has been changed to 2.5.0. The change to
1655 keep it programmatically in sync with the Python version running
1656 the code (introduced in 2.5b3) has been reverted. It will continue
1657 to be maintained manually as static string literal.
1658
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001659- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001660 and this cannot be converted to the required C type, an exception is
1661 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001662 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001663
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001664- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001665 an exception.
1666
Tim Petersc10c9d02006-09-05 02:18:09 +00001667- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001668 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001669 workarounds for clocks with low resolution, to stop the code yielding
1670 duplicate UUIDs.
1671
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001672- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1673 before raising SystemExit, allowing IDLE to honor quit() and exit().
1674
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001675- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1676
Georg Brandl7a1af772006-08-14 21:55:28 +00001677- Patch #1536071: trace.py should now find the full module name of a
1678 file correctly even on Windows.
1679
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001680- logging's atexit hook now runs even if the rest of the module has
1681 already been cleaned up.
1682
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001683- Bug #1112549, fix DoS attack on cgi.FieldStorage.

1686 str(exception) raised an exception.
1687
Neil Schemenauer06ded092006-08-04 16:20:30 +00001688- Fix a bug in the ``compiler`` package that caused invalid code to be
1689 generated for nested functions.

1702
Thomas Heller86720042006-08-14 11:17:48 +00001703- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1704 uses the _as_parameter_ attribute when objects are passed to foreign
1705 function calls. The ctypes version number was changed to 1.0.1.
1706
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001707- Bug #1530559, struct.pack raises TypeError where it used to convert.
1708 Passing float arguments to struct.pack when integers are expected
1709 now triggers a DeprecationWarning.

Andrew MacIntyre16ee33a2006-08-06 12:37:03 +00001722- test_threading now skips testing alternate thread stack sizes on
1723 platforms that don't support changing thread stack size.

1749 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1750 the documentation was changed to state that the return value
1751 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001754What's New in Python 2.5 beta 3?
1755================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001756
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001757*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001758
1759Core and builtins
1760-----------------
1761
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001762- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001763 returned a long (see PEP 353).
1764
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001765- Bug #1515471: string.replace() accepts character buffers again.
1766
Neal Norwitz07aadb12006-07-30 06:55:48 +00001767- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1768 This provides the proper warning for struct.pack().
1769 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1770
Neal Norwitz0d62a062006-07-30 06:53:31 +00001771- Patch #1531113: Fix augmented assignment with yield expressions.
1772 Also fix a SystemError when trying to assign to yield expressions.
1773
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001774- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1775 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1776 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1777 excessive filesystem operations during imports.
1778
Tim Petersbc24eee2006-07-27 01:14:53 +00001779- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1780 operations on signed longs that are formally undefined by C.
1781 Unfortunately, at least one compiler now cares about that, so complicated
1782 the code to make that compiler happy again.
1783
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001784- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1785
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001786- Patch #1232023: Stop including current directory in search
1787 path on Windows.
1788
Neal Norwitze1fdb322006-07-21 05:32:28 +00001789- Fix some potential crashes found with failmalloc.
1790
Neal Norwitze7563102006-07-17 01:00:16 +00001791- Fix warnings reported by Klocwork's static analysis tool.
1792
Neal Norwitz84be93b2006-07-16 01:50:38 +00001793- Bug #1512814, Fix incorrect lineno's when code within a function
1794 had more than 255 blank lines.
1795
Georg Brandl9dceedb2006-07-12 15:31:17 +00001796- Patch #1521179: Python now accepts the standard options ``--help`` and
1797 ``--version`` as well as ``/?`` on Windows.
1798
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001799- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001800 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001801 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001802
Tim Peters112aad32006-07-19 00:03:19 +00001803- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001804 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001805 new ``sys._current_frames()`` returns a dictionary with one entry,
1806 mapping the faux "thread id" 0 to the current frame.
1807
Ronald Oussoren3075e162006-07-25 20:28:55 +00001808- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

1812-------
1813
Facundo Batista6e22be72008-01-19 18:45:46 +00001814- Fix #1693149. Now you can pass several modules separated by
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00001815 comma to trace.py in the same --ignore-module option.
Facundo Batista6e22be72008-01-19 18:45:46 +00001816
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001817- Correction of patch #1455898: In the mbcs decoder, set final=False
1818 for stream decoder, but final=True for the decode function.
1819
Georg Brandl07fec3a2006-08-01 18:49:24 +00001820- os.urandom no longer masks unrelated exceptions like SystemExit or
1821 KeyboardInterrupt.
1822
Tim Peters4643c2f2006-08-10 22:45:34 +00001823- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001824 shutil.copytree on Windows
1825
Georg Brandle34ac7c2006-07-30 11:07:23 +00001826- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1827 refers to file descriptors, not file objects.
1828
Tim Petersc10c9d02006-09-05 02:18:09 +00001829- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001830 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001831 #1513611, and probably others.
1832
Georg Brandledd9b0d2006-07-29 09:33:26 +00001833- Bug #1441397: The compiler module now recognizes module and function
1834 docstrings correctly as it did in Python 2.4.
1835
Tim Peters6f681472006-07-27 23:44:37 +00001836- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1837 lost that tests are sorted by name before being run. This rarely
1838 matters for well-written tests, but can create baffling symptoms if
1839 side effects from one test to the next affect outcomes. ``DocTestFinder``
1840 has been changed to sort the list of tests it returns.
1841
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001842- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001843 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001844
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001845- Bug #978833: Really close underlying socket in _socketobject.close.
1846
Georg Brandl8c036cc2006-08-20 13:15:39 +00001847- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1848 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001849
Georg Brandlcf0c1722006-07-26 07:23:32 +00001850- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1851 to recursive calls and call it with the failing package name.
1852
Martin v. Löwis0b483032006-07-25 09:53:12 +00001853- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1854
Georg Brandlc13c34c2006-07-24 14:09:56 +00001855- Patch #1515343: Fix printing of deprecated string exceptions with a
1856 value in the traceback module.
1857
Greg Ward48fae7a2006-07-23 16:05:51 +00001858- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1859
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001860- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1861
Brett Cannoncaebe222006-07-18 04:41:36 +00001862- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1863 argument tuple. For arguments where zero is illegal, the value is forced to
1864 the minimum value that is correct. This is to support an undocumented but
1865 common way people used to fill in inconsequential information in the time
1866 tuple pre-2.4.
1867
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001868- Patch #1220874: Update the binhex module for Mach-O.
1869
Barry Warsawb110bad2006-07-21 14:51:07 +00001870- The email package has improved RFC 2231 support, specifically for
1871 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1872 (name*0=<blah>) parameter continuations. This may change the types of
1873 values returned from email.message.Message.get_param() and friends.
1874 Specifically in some cases where non-encoded continuations were used,
1875 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1876 will just return the string (since non-encoded continuations don't have
1877 charset and language parts).
1878
1879 Also, whereas % values were decoded in all parameter continuations, they are
1880 now only decoded in encoded parameter parts.
1881
Ronald Oussoren3075e162006-07-25 20:28:55 +00001882- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1883
1884- Bug #1517996: IDLE now longer shows the default Tk menu when a
1885 path browser, class browser or debugger is the frontmost window on MacOS X
1886
Barry Warsaw00decd72006-07-27 23:43:15 +00001887- Patch #1520294: Support for getset and member descriptors in types.py,
1888 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1889 of an object against these built-in types and more importantly, for getting
1890 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001893Extension Modules
1894-----------------
1895
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001896- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1897 a socket operation on a socket with a timeout, the exception will be
1898 caught correctly. Previously, the exception was not caught.
1899
Thomas Heller1393d6a2006-07-28 21:43:20 +00001900- Patch #1529514: The _ctypes extension is now compiled on more
1901 openbsd target platforms.
1902
Tim Peters9cab5932006-07-28 00:30:00 +00001903- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1904 a memory leak, affecting pickles and deep copies.
1905
Tim Petersbc24eee2006-07-27 01:14:53 +00001906- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001907 Paul Eggert.
1908
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001909- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1910
Thomas Hellerce049a02006-07-14 17:51:14 +00001911- Patch #1521817: Index range checking on ctypes arrays containing
1912 exactly one element enabled again. This allows iterating over these
1913 arrays, without the need to check the array size before.
1914
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001915- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001916 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001917 /dev/null in certain cases; this is now fixed.
1918
Thomas Heller47d7a062006-07-12 08:43:47 +00001919- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1920 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001921
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001922- Because of a misspelled preprocessor symbol, ctypes was always
1923 compiled without thread support; this is now fixed.
1924
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001925- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1926 methods now allow their database parameter to be None as the
1927 sleepycat API allows.
1928
Matt Flemingec926502006-07-28 11:27:27 +00001929- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1930 bluetooth API compared with Linux and FreeBSD.
1931
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001932Tests
1933-----
1934
1935- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1936 how long the test file should take to play. Now accepts taking 2.93 secs
1937 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1938
Georg Brandl4793aa32006-07-28 18:31:39 +00001939- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1940 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1941 run via ``regrtest.py``. Now they do.

1951- PythonLauncher now works correctly when the path to the script contains
1952 characters that are treated specially by the shell (such as quotes).
1953
1954- Bug #1527397: PythonLauncher now launches scripts with the working directory
1955 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001956 directory. That latter was an implementation accident and not what users

Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001968- Bug #1441486: The literal representation of -(sys.maxint - 1)
1969 again evaluates to a int object, not a long.
1970
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001971- Bug #1501934: The scope of global variables that are locally assigned
1972 using augmented assignment is now correctly determined.
1973
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001974- Bug #927248: Recursive method-wrapper objects can now safely

1976
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001977- Bug #1417699: Reject locale-specific decimal point in float()
1978 and atof().
1979
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001980- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1981 omit a default "error" argument for NULL pointer. This allows
1982 the parser to take a codec from cjkcodecs again.

Neal Norwitzfb48afa2006-07-08 05:31:37 +00001984- Bug #1519018: 'as' is now validated properly in import statements.
1985
Neal Norwitz28746ab2006-07-09 22:14:42 +00001986- On 64 bit systems, int literals that use less than 64 bits are
1987 now ints rather than longs.
1988
Neal Norwitzed657552006-07-10 00:04:44 +00001989- Bug #1512814, Fix incorrect lineno's when code at module scope
1990 started after line 256.
1991
Tim Peters32a83612006-07-10 21:08:24 +00001992- New function ``sys._current_frames()`` returns a dict mapping thread
1993 id to topmost thread stack frame. This is for expert use, and is
1994 especially useful for debugging application deadlocks. The functionality
1995 was previously available in Fazal Majid's ``threadframe`` extension
1996 module, but it wasn't possible to do this in a wholly threadsafe way from
1997 an extension.

2014
Thomas Woutersadd19112006-07-05 11:03:49 +00002015- string.Template() now correctly handles tuple-values. Previously,
2016 multi-value tuples would raise an exception and single-value tuples would
2017 be treated as the value they contain, instead.
2018
Martin v. Löwisede77f52006-07-03 13:01:35 +00002019- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
2020 even if some data are received.

2026 degrees and radians.
2027
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00002028- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00002029 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00002030

2032 is created.
2033
Martin v. Löwis7596e832006-07-01 15:33:37 +00002034- Bug #1513223: .close() of a _socketobj now releases the underlying

2038 attribute values.
2039
2040- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
2041 sgmllib ('[' and ']' were not accepted).

Georg Brandl1be63af2006-06-28 20:23:25 +00002043- Fix a bug in the turtle module's end_fill function.
2044
Brett Cannon53ab5b72006-06-22 16:49:14 +00002045- Bug #1510580: The 'warnings' module improperly required that a Warning
2046 category be either a types.ClassType and a subclass of Warning. The proper
2047 check is just that it is a subclass with Warning as the documentation states.
2048
Georg Brandlad29e632006-06-21 17:45:17 +00002049- The compiler module now correctly compiles the new try-except-finally
2050 statement (bug #1509132).
2051
Neal Norwitz60373cd2006-06-22 06:30:50 +00002052- The wsgiref package is now installed properly on Unix.
2053

2055 shutdown when fileConfig() was called multiple times.
2056
Gerhard Häring762fbd32006-07-02 17:48:30 +00002057- The sqlite3 module did cut off data from the SQLite database at the first
2058 null character before sending it to a custom converter. This has been fixed
2059 now.
2060
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00002061Extension Modules
2062-----------------
2063
Tim Peters112aad32006-07-19 00:03:19 +00002064- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
2065 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
2066 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00002067
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00002068- Assigning None to pointer type fields in ctypes structures possible
2069 overwrote the wrong fields, this is fixed now.
2070
2071- Fixed a segfault in _ctypes when ctypes.wintypes were imported
2072 on non-Windows platforms.
2073
2074- Bug #1518190: The ctypes.c_void_p constructor now accepts any
2075 integer or long, without range checking.
2076
2077- Patch #1517790: It is now possible to use custom objects in the ctypes
2078 foreign function argtypes sequence as long as they provide a from_param
2079 method, no longer is it required that the object is a ctypes type.
2080
2081- The '_ctypes' extension module now works when Python is configured
2082 with the --without-threads option.
2083
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00002084- Bug #1513646: os.access on Windows now correctly determines write
2085 access, again.
2086
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00002087- Bug #1512695: cPickle.loads could crash if it was interrupted with
2088 a KeyboardInterrupt.
2089
Neal Norwitza12aa882006-07-06 06:45:08 +00002090- Bug #1296433: parsing XML with a non-default encoding and
2091 a CharacterDataHandler could crash the interpreter in pyexpat.
2092
Neal Norwitz2a30cd02006-07-10 01:18:57 +00002093- Patch #1516912: improve Modules support for OpenVMS.

2096-----
2097
Martin v. Löwisd73168d2006-07-14 09:58:55 +00002098- Automate Windows build process for the Win64 SSL module.
2099
Tim Peters32a83612006-07-10 21:08:24 +00002100- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00002101 Previously, the slight difference could cause compilation errors of the
2102 'zlib' module on systems with more than one version of zlib.
2103
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00002104- The MSI compileall step was fixed to also support a TARGETDIR
2105 with spaces in it.

Martin v. Löwis88ef6372006-07-06 06:55:58 +00002107- Bug #1517388: sqlite3.dll is now installed on Windows independent
2108 of Tcl/Tk.
2109
Neal Norwitzc315a0f2006-06-27 04:28:56 +00002110- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00002111 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +00002112
Neal Norwitzb15ac312006-06-29 04:10:08 +00002113Tests
2114-----

2116- Call os.waitpid() at the end of tests that spawn child processes in order
2117 to minimize resources (zombies).
2118
Martin v. Löwis1bf59592006-06-29 18:58:44 +00002119Documentation
2120-------------
2121
Nick Coghlan2d792252006-07-06 13:47:18 +00002122- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
2123 documentation for the warnings module.
2124
Martin v. Löwis1bf59592006-06-29 18:58:44 +00002125- Patch #1509163: MS Toolkit Compiler no longer available.
2126
Neal Norwitz56640df2006-07-10 02:36:41 +00002127- Patch #1504046: Add documentation for xml.etree.

Nick Coghlanc649ec52006-05-29 12:43:05 +00002130What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00002131================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00002132
Anthony Baxterd1136802006-06-19 12:04:15 +00002133*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00002134
2135Core and builtins
2136-----------------
2137
Georg Brandla56b9152006-06-19 06:35:54 +00002138- Patch #1507676: Error messages returned by invalid abstract object operations
2139 (such as iterating over an integer) have been improved and now include the
2140 type of the offending object to help with debugging.
2141
Brett Cannonea3912b2006-06-13 21:46:41 +00002142- Bug #992017: A classic class that defined a __coerce__() method that returned
2143 its arguments swapped would infinitely recurse and segfault the interpreter.
2144
Neal Norwitz909eb122006-06-12 02:13:21 +00002145- Fix the socket tests so they can be run concurrently.
2146
Neal Norwitzb9845e72006-06-12 02:11:18 +00002147- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00002148 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00002149
Brett Cannon22565aa2006-06-09 22:31:23 +00002150- Bug #532646: object.__call__() will continue looking for the __call__
2151 attribute on objects until one without one is found. This leads to recursion
2152 when you take a class and set its __call__ attribute to an instance of the
2153 class. Originally fixed for classic classes, but this fix is for new-style.
2154 Removes the infinite_rec_3 crasher.
2155
Georg Brandl24250812006-06-09 18:45:48 +00002156- The string and unicode methods startswith() and endswith() now accept
2157 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
2158
Brett Cannonde3b0522006-06-08 17:00:45 +00002159- Buffer objects, at the C level, never used the char buffer
2160 implementation even when the char buffer for the wrapped object was
2161 explicitly requested (originally returned the read or write buffer).
2162 Now a TypeError is raised if the char buffer is not present but is
2163 requested.
2164
Georg Brandlddbaa662006-06-04 21:56:52 +00002165- Patch #1346214: Statements like "if 0: suite" are now again optimized
2166 away like they were in Python 2.4.
2167
Georg Brandlb7c8f542006-05-27 12:30:25 +00002168- Builtin exceptions are now full-blown new-style classes instead of
2169 instances pretending to be classes, which speeds up exception handling
2170 by about 80% in comparison to 2.5a2.
2171
Martin v. Löwisd004fc82006-05-27 08:36:52 +00002172- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
2173 Unicode 4.1.
2174
Georg Brandlf4ef1162006-05-26 18:03:31 +00002175- Patch #921466: sys.path_importer_cache is now used to cache valid and
2176 invalid file paths for the built-in import machinery which leads to
2177 fewer open calls on startup.
2178
Tim Peters696cf432006-05-24 21:10:40 +00002179- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
2180 of-2 bases. The largest speedup is for inputs with about 1000 decimal
2181 digits. Conversion from non-power-of-2 bases remains quadratic-time in
2182 the number of input digits (it was and remains linear-time for bases
2183 2, 4, 8, 16 and 32).
2184
Tim Petersb713ec22006-05-23 18:45:30 +00002185- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
2186 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
2187 an integer close to ``sys.maxint``. This was repaired by patch
2188 #1335972, which also gives a nice speedup.
2189
Richard Jonescebbefc2006-05-23 18:28:17 +00002190- Patch #1337051: reduced size of frame objects.
2191
2192- PyErr_NewException now accepts a tuple of base classes as its
2193 "base" parameter.
2194
Richard Jones7c88dcc2006-05-23 10:37:38 +00002195- Patch #876206: function call speedup by retaining allocated frame
2196 objects.
2197
Georg Brandl7b90e162006-05-18 07:01:27 +00002198- Bug #1462152: file() now checks more thoroughly for invalid mode
2199 strings and removes a possible "U" before passing the mode to the
2200 C library function.
2201
Neal Norwitz1004a532006-05-15 07:17:23 +00002202- Patch #1488312, Fix memory alignment problem on SPARC in unicode
2203
Neal Norwitz373f0a72006-05-15 07:04:36 +00002204- Bug #1487966: Fix SystemError with conditional expression in assignment
2205
Martin v. Löwis879768d2006-05-11 13:28:43 +00002206- WindowsError now has two error code attributes: errno, which carries
2207 the error values from errno.h, and winerror, which carries the error
2208 values from winerror.h. Previous versions put the winerror.h values
2209 (from GetLastError()) into the errno attribute.
2210
Martin v. Löwis77736712006-05-04 05:51:03 +00002211- Patch #1475845: Raise IndentationError for unexpected indent.
2212
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00002213- Patch #1479181: split open() and file() from being aliases for each other.
2214
Tim Peters44bd9862006-06-01 13:49:23 +00002215- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
2216 methods were always silently ignored by dictionaries when comparing keys.
2217 They are now passed through (except when using the C API function
2218 ``PyDict_GetItem()``, whose semantics did not change).
2219
2220- Bug #1456209: In some obscure cases it was possible for a class with a
2221 custom ``__eq__()`` method to confuse dict internals when class instances
2222 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
2223 No, you don't have any code that did this ;-)

2231
Brett Cannon6ee7d012006-06-08 16:23:04 +00002232- Change binascii.hexlify to accept a read-only buffer instead of only a char
2233 buffer and actually follow its documentation.
2234
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00002235- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
2236
Nick Coghlanc649ec52006-05-29 12:43:05 +00002237- Patch #1478788 (modified version): The functional extension module has
2238 been renamed to _functools and a functools Python wrapper module added.
2239 This provides a home for additional function related utilities that are
2240 not specifically about functional programming. See PEP 309.
2241
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00002242- Patch #1493701: performance enhancements for struct module.

Georg Brandl8d3342b2006-05-16 07:38:27 +00002246- Patch #1435422: zlib's compress and decompress objects now have a
2247 copy() method.
2248
Andrew MacIntyre92913322006-06-13 15:04:24 +00002249- Patch #1454481: thread stack size is now tunable at runtime for thread
2250 enabled builds on Windows and systems with Posix threads support.
2251
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002252- On Win32, os.listdir now supports arbitrarily-long Unicode path names
2253 (up to the system limit of 32K characters).
2254
2255- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
2256 As a result, these functions now raise WindowsError instead of OSError.
2257
Tim Peters7a822da2006-05-25 21:50:17 +00002258- ``time.clock()`` on Win64 should use the high-performance Windows
2259 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
2260 Windows platforms).
2261
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002262- Calling Tk_Init twice is refused if the first call failed as that
2263 may deadlock.
2264
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00002265- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
2266 accept it without potentially using an uninitialized pointer.
2267
2268- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
2269 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
2270 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00002271
Gregory P. Smith372b5832006-06-05 18:48:21 +00002272- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00002273 [pybsddb project SF patch number 1466734]
2274
Gregory P. Smith372b5832006-06-05 18:48:21 +00002275- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
2276 parameter is supplied. [SF pybsddb bug #1477863]
2277
Gregory P. Smith3c228b12006-06-05 23:59:37 +00002278- bsddb: the __len__ method of a DB object has been fixed to return correct
2279 results. It could previously incorrectly return 0 in some cases.
2280 Fixes SF bug 1493322 (pybsddb bug 1184012).
2281
Gregory P. Smithff7d9912006-06-08 05:17:08 +00002282- bsddb: the bsddb.dbtables Modify method now raises the proper error and
2283 aborts the db transaction safely when a modifier callback fails.
2284 Fixes SF python patch/bug #1408584.
2285
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002286- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00002287 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002288 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
2289 database calls that would previously deadlock. [SF python bug #775414]

2313 mime.types file for determining MIME types.
2314
Georg Brandl2605ca82006-06-14 06:08:31 +00002315- Bug #1339007: Shelf objects now don't raise an exception in their
2316 __del__ method when initialization failed.
2317
Martin v. Löwisd8251432006-06-14 05:21:04 +00002318- Patch #1455898: The MBCS codec now supports the incremental mode for
2319 double-byte encodings.
2320
Tim Peters43898b42006-06-14 04:09:25 +00002321- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2322 guarantee that adjacent triples in the return list always describe
2323 non-adjacent blocks. Previously, a pair of matching blocks could end
2324 up being described by multiple adjacent triples that formed a partition
2325 of the matching pair.
2326
Greg Ward0e0c9f42006-06-11 16:24:11 +00002327- Bug #1498146: fix optparse to handle Unicode strings in option help,
2328 description, and epilog.
2329
Greg Wardd1c797e2006-06-11 14:42:41 +00002330- Bug #1366250: minor optparse documentation error.

Greg Ward7f547402006-06-11 00:40:49 +00002332- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
2333 clarify docs.
2334
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002335- The wsgiref package has been added to the standard library.
2336
Nick Coghlan676725d2006-06-08 13:54:49 +00002337- The functions update_wrapper() and wraps() have been added to the functools
2338 module. These make it easier to copy relevant metadata from the original
2339 function when writing wrapper functions.
2340
Tim Petersd6a9eef2006-06-05 01:48:21 +00002341- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2342 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002343
Martin v. Löwis3f767792006-06-04 19:36:28 +00002344- Patch #1359618: Speed up charmap encoder by using a trie structure
2345 for lookup.
2346
Tim Petersd609b1a2006-06-02 23:22:51 +00002347- The functions in the ``pprint`` module now sort dictionaries by key
2348 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2349 if and only if its display required more than one line, although that
2350 wasn't documented. The new behavior increases predictability; e.g.,
2351 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2352
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002353- Patch #1497027: try HTTP digest auth before basic auth in urllib2

2362
Georg Brandlb89316f2006-05-17 15:51:16 +00002363- Patch #1180296: Two new functions were added to the locale module:
2364 format_string() to get the effect of "format % items" but locale-aware,
2365 and currency() to format a monetary number with currency sign.
2366
Georg Brandle3a25832006-05-17 14:56:04 +00002367- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2368 and several features added, such as speed and geometry control.
2369
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002370- Patch #1488881: add support for external file objects in bz2 compressed
2371 tarfiles.
2372
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002373- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2374 stdout arguments, making it possible to redirect input and output
2375 for remote debugging.
2376
2377- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2378 a couple of issues, notably handling of long file names using the
2379 GNU LONGNAME extension.
2380
2381- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2382 new flag when ``name`` is already the name of an option flag.
2383
2384- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2385 package.
2386
2387- Patch #1472854: make the rlcompleter.Completer class usable on non-
2388 UNIX platforms.
2389

Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00002392- Bug #1472827: correctly escape newlines and tabs in attribute values in
2393 the saxutils.XMLGenerator class.

2429-----------------
2430
Thomas Heller1b046642006-04-18 18:51:06 +00002431- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2432 by converting these apis from macros into exported functions again:
2433
2434 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2435 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2436 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2437 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2438 PyRun_String Py_CompileString
2439
Martin v. Löwis45294a92006-04-18 06:24:08 +00002440- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2441
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002442- All uses of PyStructSequence_InitType have been changed to initialize
2443 the type objects only once, even if the interpreter is initialized
2444 multiple times.
2445
Neal Norwitz61546162006-04-14 05:20:28 +00002446- Bug #1454485, array.array('u') could crash the interpreter. This was
2447 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2448 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2449
2450- Py_UNICODE is unsigned. It was always documented as unsigned, but
2451 due to a bug had a signed value in previous versions.
2452
Tim Peters3a5e8b12006-04-11 01:44:07 +00002453- Patch #837242: ``id()`` of any Python object always gives a positive
2454 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2455 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002456 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002457 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002458
Tim Peters3a5e8b12006-04-11 01:44:07 +00002459 def __hash__(self):
2460 return id(self) # WRONG
2461
2462 because a hash result must be a (short) Python int but it was always
2463 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002464 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002465 was always usable as a hash value before this patch. That's no longer
2466 necessarily so.
2467
2468- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002469 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002470 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002471 #1454844)
2472
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002473- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2474 involving generators that have paused outside of any ``try`` or ``with``
2475 blocks. (In 2.5a1, a paused generator that was part of a reference
2476 cycle could not be garbage collected, regardless of whether it was
2477 paused in a ``try`` or ``with`` block.)

2491 the cachesize parameter.
2492
2493- Bug #1149413: bsddb.*open() no longer raises an exception when using
2494 a temporary db (file=None) with the 'n' flag to truncate on open.

2496- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2497 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002498
Armin Rigoa9017c32006-04-19 11:50:27 +00002499- Patch #1062014: AF_UNIX sockets under Linux have a special

2507 abusing errno.
2508
Tim Peters711bf302006-04-25 03:31:36 +00002509- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2510 a doctest to be skipped (the code is not run, and the expected output
2511 or exception is ignored).
2512
Nick Coghlanda2268f2006-04-24 04:37:15 +00002513- Fixed contextlib.nested to cope with exceptions being raised and
2514 caught inside exit handlers.
2515
Greg Wardab05edc2006-04-23 03:47:58 +00002516- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2517 hex, octal, or binary; add ``append_const`` action; keep going if
2518 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2519 added ``epilog`` for better help generation).
2520
Tim Peters21fbd572006-04-21 21:18:10 +00002521- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2522 called from a thread spawned as a side effect of importing a module.
2523
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002524- The pydoc module now supports documenting packages contained in
2525 .zip or .egg files.
2526
2527- The pkgutil module now has several new utility functions, such
2528 as ``walk_packages()`` to support working with packages that are either
2529 in the filesystem or zip files.
2530
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002531- The mailbox module can now modify and delete messages from
2532 mailboxes, in addition to simply reading them. Thanks to Gregory
2533 K. Johnson for writing the code, and to the 2005 Google Summer of
2534 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002535
Tim Petersc7605f22006-04-17 21:12:33 +00002536- The ``__del__`` method of class ``local`` in module ``_threading_local``
2537 returned before accomplishing any of its intended cleanup.
2538
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002539- Patch #790710: Add breakpoint command lists in pdb.

2547
Phillip J. Eby47032112006-04-11 01:07:43 +00002548- The warnings, linecache, inspect, traceback, site, and doctest modules

2573 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002574 specified. (Can be overridden by explicitly setting LINKCC.) Decouple

2580
Tim Peters8931ff12006-05-13 23:28:20 +00002581- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2582 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,

2584
Anthony Baxter51bcb682006-04-05 14:51:42 +00002585Tests
2586-----
2587
Nick Coghlanda2268f2006-04-24 04:37:15 +00002588- test_contextlib now checks contextlib.nested can cope with exceptions
2589 being raised and caught inside exit handlers.

2592
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002593- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2594 it separately and by hand. It also wasn't cleaning up its changes to
2595 the current Decimal context.
2596
Thomas Woutersabd08882006-04-26 15:53:30 +00002597- regrtest.py now has a -M option to run tests that test the new limits of
2598 containers, on 64-bit architectures. Running these tests is only sensible
2599 on 64-bit machines with more than two gigabytes of memory. The argument
2600 passed is the maximum amount of memory for the tests to use.

2609-------------
2610
Tim Petersb06d28c2006-05-12 01:57:59 +00002611- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2612
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002613- PEP 343: Added Context Types section to the library reference
2614 and attempted to bring other PEP 343 related documentation into
2615 line with the implementation and/or python-dev discussions.
2616
Tim Peters8dc73d22006-04-24 02:03:16 +00002617- Bug #1337990: clarified that ``doctest`` does not support examples
2618 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002626Core and builtins
2627-----------------
2628
Nick Coghlan43832302006-04-23 17:04:07 +00002629- PEP 338: -m command line switch now delegates to runpy.run_module
2630 allowing it to support modules in packages and zipfiles
2631
Martin v. Löwisc661b882006-04-20 04:54:23 +00002632- On Windows, .DLL is not an accepted file name extension for
2633 extension modules anymore; extensions are only found if they
2634 end in .PYD.
2635
Martin v. Löwisea62d252006-04-03 10:56:49 +00002636- Bug #1421664: sys.stderr.encoding is now set to the same value as
2637 sys.stdout.encoding.
2638
Neal Norwitz92e212f2006-04-03 04:48:37 +00002639- __import__ accepts keyword arguments.
2640
Georg Brandlccadf842006-03-31 18:54:53 +00002641- Patch #1460496: round() now accepts keyword arguments.
2642
Anthony Baxter262c00a2006-03-30 10:53:17 +00002643- Fixed bug #1459029 - unicode reprs were double-escaped.
2644
Hye-Shik Changd478f342006-03-23 12:32:36 +00002645- Patch #1396919: The system scope threads are reenabled on FreeBSD
2646 5.4 and later versions.
2647
Neal Norwitze98ccf62006-03-23 05:39:47 +00002648- Bug #1115379: Compiling a Unicode string with an encoding declaration
2649 now gives a SyntaxError.
2650
Georg Brandlabd1ff82006-03-18 07:59:59 +00002651- Previously, Python code had no easy way to access the contents of a
2652 cell object. Now, a ``cell_contents`` attribute has been added
2653 (closes patch #1170323).
2654
Tim Peterscf79aac2006-03-16 01:14:46 +00002655- Patch #1123430: Python's small-object allocator now returns an arena to
2656 the system ``free()`` when all memory within an arena becomes unused
2657 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2658 freed. Some applications will see a drop in virtual memory size now,
2659 especially long-running applications that, from time to time, temporarily
2660 use a large number of small objects. Note that when Python returns an
2661 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002662 platform C library will in turn return that memory to the operating system.
2663 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002664 appears to be effective at least on Microsoft C and gcc-based systems.
2665 Thanks to Evan Jones for hard work and patience.
2666
Georg Brandl533ff6f2006-03-08 18:09:27 +00002667- Patch #1434038: property() now uses the getter's docstring if there is
2668 no "doc" argument given. This makes it possible to legitimately use
2669 property() as a decorator to produce a read-only property.
2670
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002671- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2672 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2673 of requiring an int or long in slicing and a few other contexts, enabling
2674 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2675
Neal Norwitz995acdf2006-03-07 05:01:00 +00002676- Fixed various bugs reported by Coverity's Prevent tool.
2677
Brett Cannonbf364092006-03-01 04:25:17 +00002678- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2679 new exception base class, BaseException, which has a new message attribute.
2680 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2681 Raising a string exception now raises a DeprecationWarning.
2682
Thomas Woutersfb609f42006-02-28 16:37:25 +00002683- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2684 explicitly relative, using 'from .module import name' to mean 'from the same
2685 package as this module is in. Imports without dots still default to the
2686 old relative-then-absolute, unless 'from __future__ import
2687 absolute_import' is used.
2688
Brett Cannona7446e32006-02-27 23:39:10 +00002689- Properly check if 'warnings' raises an exception (usually when a filter set
2690 to "error" is triggered) when raising a warning for raising string
2691 exceptions.
2692
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002693- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002694 The name was removed from Include/code.h.
2695
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002696- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002697
Guido van Rossum1968ad32006-02-25 22:38:04 +00002698- Patch 1433928:
2699 - The copy module now "copies" function objects (as atomic objects).
2700 - dict.__getitem__ now looks for a __missing__ hook before raising
2701 KeyError.
2702
Tim Peters84ef21c2006-02-28 20:39:06 +00002703- PEP 343: with statement implemented. Needs ``from __future__ import
2704 with_statement``. Use of 'with' as a variable will generate a warning.
2705 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002706 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002707 The following objects have __context__ methods:
2708 - The built-in file type.
2709 - The thread.LockType type.
2710 - The following types defined by the threading module:
2711 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2712 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002713
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002714- Fix the encodings package codec search function to only search
2715 inside its own package. Fixes problem reported in patch #1433198.
2716
2717 Note: Codec packages should implement and register their own
2718 codec search function. PEP 100 has the details.
2719
Tim Peters9ea89d22006-06-04 03:26:02 +00002720- PEP 353: Using ``Py_ssize_t`` as the index type.
2721
2722- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2723 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2724 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2725 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2726 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002727
Neal Norwitzfc76d632006-01-10 06:03:13 +00002728- Patch #1400181, fix unicode string formatting to not use the locale.
2729 This is how string objects work. u'%f' could use , instead of .
2730 for the decimal point. Now both strings and unicode always use periods.
2731
Neal Norwitz671b9e32006-01-09 07:07:12 +00002732- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2733 configure would break checking curses.h.
2734
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002735- Bug #959576: The pwd module is now builtin. This allows Python to be
2736 built on UNIX platforms without $HOME set.
2737
Neal Norwitzc10978f2005-12-19 06:07:16 +00002738- Bug #1072182, fix some potential problems if characters are signed.
2739
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002740- Bug #889500, fix line number on SyntaxWarning for global declarations.
2741
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002742- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2743
Neal Norwitze7214a12005-12-18 05:03:17 +00002744- Support for converting hex strings to floats no longer works.
2745 This was not portable. float('0x3') now raises a ValueError.
2746
Barry Warsaw2a38a862005-12-18 01:27:35 +00002747- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002748 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002749 is now displayed in interactive prompt banner.
2750
Georg Brandlfa166682005-12-17 21:45:17 +00002751- Implementation of PEP 341 - Unification of try/except and try/finally.
2752 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002753 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002754
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002755- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2756 now encodes backslash correctly.
2757
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002758- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2759
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002760- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002761 and long longs.
2762
Neal Norwitz67715f02005-11-09 06:59:35 +00002763- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002764 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002765 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002766
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002767- Replaced most Unicode charmap codecs with new ones using the
2768 new Unicode translate string feature in the builtin charmap
2769 codec; the codecs were created from the mapping tables available
2770 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2771 encodings now include a mapping for the Apple logo)
2772
Tim Peterse3547fd2005-12-16 23:13:57 +00002773- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002774
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002775- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002776
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002777- A new AST parser implementation was completed. The abstract
2778 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002779 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002780
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002781- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002782 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2783
Neal Norwitz708e51a2005-10-03 04:48:15 +00002784- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2785
Neal Norwitz11bd1192005-10-03 00:54:56 +00002786- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2787 Provide a warning when a directory is passed on the command line.
2788
Neal Norwitz40d37812005-10-02 01:48:49 +00002789- Fix segfault with invalid coding.
2790
2791- SF bug #772896: unknown encoding results in MemoryError.
2792
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002793- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002794 supported a __len__() method which evaluated to False when the iterator
2795 was empty.
2796
Guido van Rossum630db602005-09-20 18:49:54 +00002797- On 64-bit platforms, when __len__() returns a value that cannot be
2798 represented as a C int, raise OverflowError.
2799
Skip Montanarof8948ca2005-09-19 03:54:46 +00002800- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002801 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002802
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002803- SF bug #893549: parsing keyword arguments was broken with a few format
2804 codes.
2805
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002806- Changes donated by Elemental Security to make it work on AIX 5.3
2807 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2808 bug #105470: test_pwd fails on 64bit system (Opteron).
2809
Guido van Rossum539c6622005-09-14 17:49:54 +00002810- Changes donated by Elemental Security to make it work on HP-UX 11 on
2811 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2812
Georg Brandl4550b8d2005-08-26 06:43:52 +00002813- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002814 (fixes bug #1119418).
2815
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002816- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2817
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002818- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2819 exceptions that cause a function to exit.
2820
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002821- The implementation of set() and frozenset() was revised to use its
2822 own internal data structure. Memory consumption is reduced by 1/3
2823 and there are modest speed-ups as well. The API is unchanged.
2824
Tim Petersde7990b2005-07-17 23:45:23 +00002825- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2826
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002827- SF bug #1229429: PyObject_CallMethod failed to decrement some
2828 reference counts in some error exit cases.
2829
Tim Petersecc6e6a2005-07-10 22:30:55 +00002830- SF bug #1185883: Python's small-object memory allocator took over
2831 a block managed by the platform C library whenever a realloc specified
2832 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002833 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002834 portable way to copy data from the C-managed block into Python's
2835 small-object space without risking a memory fault. Python's small-object
2836 realloc now leaves such blocks under the control of the platform C
2837 realloc.
2838
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002839- SF bug #1232517: An overflow error was not detected properly when
2840 attempting to convert a large float to an int in os.utime().
2841
Raymond Hettinger3296e692005-06-29 23:29:56 +00002842- SF bug #1224347: hex longs now print with lowercase letters just
2843 like their int counterparts.
2844
Michael W. Hudson188d4362005-06-20 16:52:57 +00002845- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2846 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2847 interpreter states; back out that fix and do a better job (see
2848 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2849 for a longer write-up of the problem).
2850
Michael W. Hudsondf888462005-06-03 14:41:55 +00002851- SF patch #1180995: marshal now uses a binary format by default when
2852 serializing floats.
2853
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002854- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2855 the routines that promise to produce IEEE 754 binary representations
2856 of floats now simply copy bytes around.
2857
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002858- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2859 278.
2860
Brett Cannonc3647ac2005-04-26 03:45:26 +00002861- patch #1109424: int, long, float, complex, and unicode now check for the
2862 proper magic slot for type conversions when subclassed. Previously the
2863 magic slot was ignored during conversion. Semantics now match the way
2864 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002865 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002866 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002867 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002868
Barry Warsawc8d907c2005-04-19 23:43:40 +00002869- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2870 NULL, now raise an AttributeError when attempting to set or delete the
2871 attribute. Previously a TypeError was raised, but this was inconsistent
2872 with the equivalent pure-Python implementation.
2873
Michael W. Hudson774479c2005-04-18 08:46:17 +00002874- It is now safe to call PyGILState_Release() before
2875 PyEval_InitThreads() (note that if there is reason to believe there
2876 are multiple threads around you still must call PyEval_InitThreads()
2877 before using the Python API; this fix is for extension modules that
2878 have no way of knowing if Python is multi-threaded yet).
2879
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002880- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2881 disabled caused a crash.
2882
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002883- Bug #1165306: instancemethod_new allowed the creation of a method
2884 with im_class == im_self == NULL, which caused a crash when called.
2885
Tim Petersecc6e6a2005-07-10 22:30:55 +00002886- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002887 fixes the crash seen in bug #1165761
2888
Raymond Hettinger96229b12005-03-11 06:49:40 +00002889- Added two new builtins, any() and all().
2890
Brett Cannon409d8f22005-03-05 06:47:57 +00002891- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002892 (e.g., ``class C(): pass`` is no longer a syntax error).
2893 Patch #1176012 added support to the 'parser' module and 'compiler' package
2894 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002895
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002896- Patch #1115086: Support PY_LONGLONG in structmember.

2899 returning None.
2900
Tim Petersecc6e6a2005-07-10 22:30:55 +00002901- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002902 ('\') with a specific error message.
2903
Martin v. Löwisff232d72005-03-03 09:24:38 +00002904- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2905
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002906- Bug #1124295: the __name__ attribute of file objects was
2907 inadvertently made inaccessible in restricted mode.
2908
Tim Petersecc6e6a2005-07-10 22:30:55 +00002909- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002910 an ferror() call.
2911
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002912- min() and max() now support key= arguments with the same meaning as in
2913 list.sort().
2914
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002915- The peephole optimizer now performs simple constant folding in expressions:
2916 (2+3) --> (5).
2917
Raymond Hettingera422c342005-01-11 03:03:27 +00002918- set and frozenset objects can now be marshalled. SF #1098985.
2919
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002920- Bug #1077106: Poor argument checking could cause memory corruption
2921 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002922
Jeremy Hyltonab630502005-02-04 18:44:06 +00002923- The parser did not complain about future statements in illegal
2924 positions. It once again reports a syntax error if a future
2925 statement occurs after anything other than a doc string.
2926
Neil Schemenauercf52c072005-08-12 17:34:58 +00002927- Change the %s format specifier for str objects so that it returns a
2928 unicode instance if the argument is not an instance of basestring and
2929 calling __str__ on the argument returns a unicode instance.
2930
Tim Petersf4e69282006-02-27 17:15:31 +00002931- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2932 current thread state when the auto-GIL-state machinery knows about
2933 it (since the thread state is being deleted, continuing to remember it
2934 can't help, but can hurt if another thread happens to get created with
2935 the same thread id).
2936

Nick Coghlan43832302006-04-23 17:04:07 +00003131- PEP 338: new module runpy defines a run_module function to support
3132 executing modules which provide access to source code or a code object
3133 via the PEP 302 import mechanisms.
3134
Anthony Baxter93f5b932006-04-03 08:05:07 +00003135- The email module's parsedate_tz function now sets the daylight savings

3143 in attribute values.
3144
Anthony Baxterc51ee692006-04-01 00:57:31 +00003145- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00003146 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00003147 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00003148 module will not be built.
3149
Tim Petersc17976e2006-04-01 00:26:53 +00003150- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
3151 aren't officially supported here, and trying to use them will probably
3152 raise an exception some day. But dicts have been allowed, and "mostly
3153 worked", so support for them won't go away without warning.
3154
Georg Brandl338ef7d2006-03-31 18:42:16 +00003155- Bug #1445068: getpass.getpass() can now be given an explicit stream

3167 to make it easier to monitor when daemon threads have completed
3168 processing all enqueued tasks. Patch #1455676.
3169
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00003170- popen2.Popen objects now preserve the command in a .cmd attribute.

3173
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00003174- email 4.0 package now integrated. This is largely the same as the email 3.0
3175 package that was included in Python 2.3, except that PEP 8 module names are
3176 now used (e.g. mail.message instead of email.Message). The MIME classes
3177 have been moved to a subpackage (e.g. email.mime.text instead of
3178 email.MIMEText). The old names are still supported for now. Several
3179 deprecated Message methods have been removed and lots of bugs have been
3180 fixed. More details can be found in the email package documentation.
3181
Walter Dörwald40108c92006-03-27 08:15:44 +00003182- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
3183 (a subclass of tuple) that provides incremental decoders and encoders
3184 (a way to use stateful codecs without the stream API). Python functions
3185 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
3186 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
3187 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00003188
Walter Dörwald067db482006-03-15 22:17:27 +00003189- Patch #1359365: Calling next() on a closed StringIO.String object raises
3190 a ValueError instead of a StopIteration now (like file and cString.String do).
3191 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
3192 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00003193
Martin v. Löwis04824ce2006-03-10 21:26:16 +00003194- A regrtest option -w was added to re-run failed tests in verbose mode.

Tim Peterse3547fd2005-12-16 23:13:57 +00003266 SHA1, 224, 256, 384, and 512. Note that recent developments make the
3267 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
3268 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
3269 Ronald L. Rivest offered this advice for Python:
3270
3271 "The consensus of researchers in this area (at least as
3272 expressed at the NIST Hash Function Workshop 10/31/05),
3273 is that SHA-256 is a good choice for the time being, but
3274 that research should continue, and other alternatives may
3275 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00003276
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00003277- Added a subset of Fredrik Lundh's ElementTree package. Available

Raymond Hettinger267b8682005-03-27 10:47:39 +00003393- decimal operator and comparison methods now return NotImplemented
3394 instead of raising a TypeError when interacting with other types. This
3395 allows other classes to implement __radd__ style methods and have them
3396 work as expected.
3397
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003398- Bug #1163325: Decimal infinities failed to hash. Attempting to
3399 hash a NaN raised an InvalidOperation instead of a TypeError.
3400
Tim Petersecc6e6a2005-07-10 22:30:55 +00003401- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00003402 stream compression; add, for symmetry reasons, r:* as a synonym of r.
3403
Martin v. Löwis00a73e72005-03-04 19:40:34 +00003404- Patch #1043890: Add extractall method to tarfile.

Martin v. Löwisc72dd382005-03-04 13:50:17 +00003406- Patch #1075887: Don't require MSVC in distutils if there is nothing
3407 to build.
3408
Martin v. Löwis637431b2005-03-03 23:12:42 +00003409- Patch #1103407: Properly deal with tarfile iterators when untarring
3410 symbolic links on Windows.
3411
Tim Petersecc6e6a2005-07-10 22:30:55 +00003412- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00003413 profile.py if available.
3414
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00003415- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
3416
Martin v. Löwisc5574e82005-03-03 10:57:37 +00003417- Patch #1117454: Remove code to special-case cookies without values
3418 in LWPCookieJar.
3419
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00003420- Patch #1117339: Add cookielib special name tests.
3421
Martin v. Löwise869eb12005-03-03 09:46:07 +00003422- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
3423
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00003424- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
3425
Martin v. Löwisdf241532005-03-03 08:17:42 +00003426- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
3427
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00003428- Patch #1104111: Alter setup.py --help and --help-commands.
3429
Martin v. Löwis4afe1542005-03-01 08:09:28 +00003430- Patch #1121234: Properly cleanup _exit and tkerror commands.
3431
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00003432- Patch #1049151: xdrlib now unpacks booleans as True or False.
3433
Raymond Hettingerbab41432005-02-05 01:31:19 +00003434- Fixed bug in a NameError bug in cookielib. Patch #1116583.
3435
Guido van Rossumd0641422005-02-03 15:01:24 +00003436- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3437 disables recursive traversal through instance attributes, which can
3438 be exploited in various ways.
3439
Tim Peterse3547fd2005-12-16 23:13:57 +00003440- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003441 flags on the HTTP listening socket.
3442
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003443- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3444 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3445
Fred Drakefbdeaad2006-07-29 16:56:15 +00003446- Patches #893642, #1039083: add allow_none, encoding arguments to
3447 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003448
Martin v. Löwis1d11de62005-01-29 13:29:23 +00003449- Bug #1110478: Revert os.environ.update to do putenv again.
3450
Thomas Hellerd6c6e222005-01-20 19:20:16 +00003451- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3452
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003453- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3454
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003455- Enhancements to the csv module:
3456
3457 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003458 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003459 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003460 + Dialect parameter parsing has been re-implemented to improve error
3461 reporting.
3462 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3463 dictates.
3464 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003465 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003466 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003467 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3468 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003469 + reader now allows \r characters to be quoted (previously it only allowed
3470 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003471 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003472 + Dialect classes passed to the module are no longer instantiated by
3473 the module before being parsed (the former validation scheme required
3474 this, but the mechanism was unreliable).
3475 + The dialect registry now contains instances of the internal
3476 C-coded dialect type, rather than references to python objects.
3477 + the internal c-coded dialect type is now immutable.
3478 + register_dialect now accepts the same keyword dialect specifications
3479 as the reader and writer, allowing the user to register dialects
3480 without first creating a dialect class.
3481 + a configurable limit to the size of parsed fields has been added -
3482 previously, an unmatched quote character could result in the entire
3483 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003484 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003485 the parser field size limit (returning the former limit). The initial
3486 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003487 + A line_num attribute has been added to the reader object, which tracks
3488 the number of lines read from the source iterator. This is not
3489 the same as the number of records returned, as records can span
3490 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003491 + reader and writer objects were not being registered with the cyclic-GC.
3492 This has been fixed.
3493
Brett Cannone6539c42005-01-08 02:43:53 +00003494- _DummyThread objects in the threading module now delete self.__block that is
3495 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3496 lock primitives tend to be limited in number and thus should not be wasted on
3497 a _DummyThread object. Fixes bug #1089632.
3498
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003499- The imghdr module now detects Exif files.
3500
Raymond Hettinger6065d322004-12-20 23:51:53 +00003501- StringIO.truncate() now correctly adjusts the size attribute.
3502 (Bug #951915).
3503
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003504- locale.py now uses an updated locale alias table (built using
3505 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3506 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003507 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003508
Raymond Hettinger3557f422004-12-07 12:02:02 +00003509- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3510
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003511- the pickle module no longer accepts the deprecated None option in the
3512 args tuple returned by __reduce__().
3513
Brett Cannon84667c02004-12-07 03:25:18 +00003514- optparse now optionally imports gettext. This allows its use in setup.py.
3515
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003516- the pickle module no longer uses the deprecated bin parameter.
3517
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003518- the shelve module no longer uses the deprecated binary parameter.
3519
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003520- the pstats module no longer uses the deprecated ignore() method.
3521
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003522- the filecmp module no longer uses the deprecated use_statcache argument.
3523
Raymond Hettinger664347b2004-12-04 21:21:53 +00003524- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3525 extended or overridden by subclasses. Formerly, the subclassed method would
3526 be ignored by the rest of the module. (Bug #1078905).
3527
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003528- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003529 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003530
Walter Dörwald36733692004-12-22 12:50:50 +00003531- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3532 once when a size argument is given. This prevents a buffer overflow in the
3533 tokenizer with very long source lines.
3534
Barry Warsaw538561e2006-01-01 21:48:54 +00003535- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3536 immediately after creating the object, without any intervening
3537 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003538
Skip Montanaro05885812005-01-16 20:48:27 +00003539- The reconvert.quote function can now emit triple-quoted strings. The
3540 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003541
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003542- ``UserString.MutableString`` now supports negative indices in
3543 ``__setitem__`` and ``__delitem__``
3544
Greg Ward40407942005-03-05 02:53:17 +00003545- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3546 correctly.
3547
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003548- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3549 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3550 character even if the user has passed a size parameter to get a proper
3551 line ending. Remove the special handling of a "\r\n" that has been split
3552 between two lines.
3553
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003554- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3555 about illegal code points. The codec now supports PEP 293 style error
3556 handlers.
3557
Walter Dörwald78a78b02005-09-01 12:04:29 +00003558- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003559 from the input stream, so that the output is a byte string in the correct
3560 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003561
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003562- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3563 considering it exactly like a '*'.
3564
Walter Dörwald007f8df2005-10-09 19:42:27 +00003565- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3566 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003567
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003568- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3569
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003570- Patch #1413711: Certain patterns of differences were making difflib
3571 touch the recursion limit.
3572
Walter Dörwald58917a62006-03-31 15:26:22 +00003573- Bug #947906: An object oriented interface has been added to the calendar
3574 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003575 called as a script (e.g. via ``python -mcalendar``). Localized month and
3576 weekday names can be ouput (even if an exotic encoding is used) using
3577 special classes that use unicode.

3581
Neal Norwitz602d3392006-03-31 08:21:40 +00003582- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3583 by using -mieee gcc option.
3584

3586
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003587- Build support for Win64-AMD64 was added.
3588
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003589- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3590
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003591- Patch #881820: look for openpty and forkpty also in libbsd.
3592
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003593- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3594 The zlib module is now builtin on Windows.
3595
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003596- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3597
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003598- Bug #1189330: configure did not correctly determine the necessary
3599 value of LINKCC if python was built with GCC 4.0.
3600
Trent Mick8321b422005-07-26 02:29:21 +00003601- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3602 vulnerability in zlib 1.2.1 and 1.2.2.
3603
Brett Cannon08cd5982005-04-24 22:26:38 +00003604- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3605 flags that change binary compatibility. Changes were also made to
3606 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003607 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003608
Bob Ippolitoed233462005-03-29 13:47:59 +00003609- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3610 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3611 no longer exists). This configure patch makes things right.
3612
Martin v. Löwise2713be2005-03-08 15:03:08 +00003613- Bug #1158607: Build with --disable-unicode again.
3614
Brett Cannon46d96232005-02-16 00:07:19 +00003615- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3616 defined. Discovered as a result of not being able to build on OS X.
3617
Brett Cannon516592f2004-12-07 00:42:59 +00003618- setup.py now uses the directories specified in LDFLAGS using the -L option
3619 and in CPPFLAGS using the -I option for adding library and include
3620 directories, respectively, for compiling extension modules against. This has
3621 led to the core being compiled using the values in CPPFLAGS. It also removes
3622 the need for the special-casing of both DarwinPorts and Fink for darwin since
3623 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3624 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3625 Fink, ``-I/opt/local/include`` for DarwinPorts).
3626
Brett Cannon43802422005-02-10 20:48:03 +00003627- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3628 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3629 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3630 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003632C API
3633-----
3634
Tim Petersc9d78aa2006-03-26 23:27:58 +00003635- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3636 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3637 is obtained via the ``PyObject_`` family, it must be released via the
3638 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3639 always been officially true, but when Python's small-object allocator was
3640 introduced, an attempt was made to cater to a few extension modules
3641 discovered at the time that obtained memory via ``PyObject_New`` but
3642 released it via ``PyMem_DEL``. It's years later, and if such code still
3643 exists it will fail now (probably with segfaults, but calling wrong
3644 low-level memory management functions can yield many symptoms).
3645
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003646- Added a C API for set and frozenset objects.
3647
Raymond Hettinger66517482004-12-03 11:45:13 +00003648- Removed PyRange_New().

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003650- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3651 mapping argument now. This string is used as a mapping table. Byte values
3652 greater than the length of the string and 0xFFFE are treated as undefined
3653 mappings.
