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.

1197 time so that opening a database previously created with the DB_DUP or
1198 DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
1199 Specifically: dictionary assignment to a DB object will replace all
1200 values for a given key when the database allows duplicate values.
1201 DB users should use DB.put(k, v) when they want to store duplicates; not
1202 DB[k] = v.
1203
Gregory P. Smithac11e022007-11-05 02:56:31 +00001204- Add the bsddb.db.DBEnv.lock_id_free method.

1426 alphatbetical order. Makes output more deterministic and easier to tell if
1427 the file is stale or not.
1428
Marc-André Lemburg96148682006-09-06 20:40:22 +00001429- Bug #1546372: Fixed small bugglet in pybench that caused a missing

1435
Brett Cannon70c0c022008-02-03 09:59:21 +00001436- Have the search path for building extensions follow the declared order in
1437 $CPPFLAGS and $LDFLAGS when adding directories from those environment
1438 variables.
1439
Christian Heimes951cc0f2008-01-31 23:08:23 +00001440- Bug #1983: Added a check to pyport to verify that sizeof(pid_t) is
1441 smaller or equal sizeof(long).
1442
Christian Heimescba36bb2008-01-30 22:54:18 +00001443- Bug #1234: Fixed semaphore errors on AIX 5.2

1446
1447- Removed PCbuild8/ directory and added a new build directory for VS 2005
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00001448 based on the VS 2008 build directory to PC/VS8.0. The script
Christian Heimes000a0742008-01-03 22:16:32 +00001449 PCbuild/vs8to9.py was added to sync changes from PCbuild to PC/VS8.0.
1450
1451- Moved PCbuild/ directory for VS 2003 to PC/VS7.1 and renamed PCBuild9/
1452 directory to PCBuild/.

1455
Guido van Rossum7c862f82007-12-13 20:50:10 +00001456- Bug #1608: use -fwrapv when GCC supports it. This is important,
1457 newer GCC versions may optimize away overflow buffer overflow checks
1458 without this option!
1459
Martin v. Löwis63bf1492007-11-12 05:14:05 +00001460- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.
1461
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00001462- Add a FAST_LOOPS build option that speeds-up looping by trading away
1463 periodic threadstate and signal checking in tight loops. By default,
1464 this option is turned-off. It should only be enabled in debugged,
1465 performance critical applications.
1466
Martin v. Löwisd44a4e92007-09-05 11:47:34 +00001467- Patch #786737: Allow building in a tree of symlinks pointing to

1477
Georg Brandldb846032007-03-31 18:56:11 +00001478- Bug #1655392: don't add -L/usr/lib/pythonX.Y/config to the LDFLAGS
1479 returned by python-config if Python was built with --enable-shared
1480 because that prevented the shared library from being used.
1481
Georg Brandl18c47f62007-03-13 10:19:22 +00001482- Patch #1569798: fix a bug in distutils when building Python from a
1483 directory within sys.exec_prefix.
1484

1490 attribute.
1491
Vinay Sajip76fdb8c2006-12-14 08:53:55 +00001492- Bug #1578513: Cross compilation was broken by a change to configure.
Martin v. Löwisfefbc202006-10-17 18:59:23 +00001493 Repair so that it's back to how it was in 2.4.3.
1494
Martin v. Löwisc9e82f62006-10-15 07:54:40 +00001495- Patch #1576954: Update VC6 build directory; remove redundant

Matthias Klose642ac852007-09-04 18:17:36 +00001508- Makefile.pre.in(buildbottest): Run an optional script pybuildbot.identify
1509 to include some information about the build environment.
1510
Georg Brandl6caad7d2008-01-26 14:19:22 +00001511
Neal Norwitz92422fb2006-08-18 03:57:54 +00001512C API
1513-----
1514
Christian Heimes5b970ad2008-02-06 13:33:44 +00001515- Unified naming convention for free lists and their limits. All free lists
1516 in Object/ are named ``free_list``, the counter ``numfree`` and the upper
1517 limit is a macro ``PyName_MAXFREELIST`` inside an #ifndef block.
1518
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00001519- ``PySet_Add()`` can now modify a newly created frozenset. Similarly to
1520 ``PyTuple_SetItem``, it can be used to populate a brand new frozenset; but
1521 it does not steal a reference to the added item.
1522
1523- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
1524
Georg Brandl6caad7d2008-01-26 14:19:22 +00001525- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format and
1526 _FormatV from Python 3.0. Made PyLong_AsSsize_t and PyLong_FromSsize_t
1527 public functions.
1528
1529- Patch #1720595: add T_BOOL to the range of structmember types.
1530
1531- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
1532 ``PyFloat_GetInfo()`` to the float API.
1533
1534- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
1535 format code incorrectly truncated the length to an int, even when
1536 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
1537 results with huge strings.
1538
1539- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE
1540 and Py_REFCNT.
1541
1542- PEP 3123: Provide forward compatibility with Python 3.0, while keeping
1543 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
1544 PyVarObject_HEAD_INIT.
1545
1546- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
1547
1548- Patch #1733960: Allow T_LONGLONG to accept ints.
1549
1550- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
1551
Christian Heimes000a0742008-01-03 22:16:32 +00001552- Added a new API function ``PyImport_ImportModuleNoBlock``.
1553
Georg Brandl6caad7d2008-01-26 14:19:22 +00001554- Bug #1637022: Prefix AST symbols with _Py_.
1555
1556- Fix some leftovers from the conversion from int to Py_ssize_t
1557 (relevant to strings and sequences of more than 2**31 items).
1558
1559- Make _PyGILState_NoteThreadState() static, it was not used anywhere
1560 outside of pystate.c and should not be necessary.
1561
Christian Heimes000a0742008-01-03 22:16:32 +00001562- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do absolute
1563 imports. In earlier versions they might have used relative imports under
1564 some conditions.
1565
Andrew M. Kuchlingadc60ab2008-01-04 02:26:00 +00001566- Added case insensitive comparison methods ``PyOS_stricmp(char*, char*)``
Christian Heimes000a0742008-01-03 22:16:32 +00001567 and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
1568
Neal Norwitz8a267062006-08-19 04:25:29 +00001569- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx macro
1570 so it can be used as an expression.

1574-------
1575
Christian Heimes95d64472008-02-09 19:55:22 +00001576- Patch #1706: Drop support for Win9x, WinME and NT4. Python now requires
1577 Windows 2000 or greater. The _WINVER and NTDDI_VERSION macros are set to
1578 Win2k for x86/32bit builds and WinXP for AMD64 builds.
1579
Martin v. Löwis2607e6c2006-11-21 18:20:25 +00001580- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE
1581 and _CRT_NONSTDC_NO_DEPRECATE.
1582
Martin v. Löwisd476a402007-10-12 08:56:52 +00001583- Bug #1216: Restore support for Visual Studio 2002.

Brett Cannonf0cb1d72007-05-31 20:01:11 +00001589- cfmfile now raises a DeprecationWarning.
1590
Brett Cannon791d56f2007-05-31 19:40:42 +00001591- buildtools now raises a DeprecationWarning.
1592
Brett Cannon5e263512007-05-20 23:17:38 +00001593- Removed the macfs module. It had been deprecated since Python 2.5. This
1594 lead to the deprecation of macostools.touched() as it relied solely on macfs
1595 and was a no-op under OS X.

1604-----------------
1605
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001606- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001607 compared equal or unequal to a string and a UnicodeDecodeError
1608 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001609
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001610 Instead, the equal (==) and unequal (!=) comparison operators will
1611 now issue a UnicodeWarning and interpret the two objects as
1612 unequal. The UnicodeWarning can be filtered as desired using
1613 the warning framework, e.g. silenced completely, turned into an
1614 exception, logged, etc.
1615
1616 Note that compare operators other than equal and unequal will still
1617 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001618
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001619- Fix segfault when doing string formatting on subclasses of long.
1620
1621- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1622 with new-style classes.
1623
1624- Fix bug related to __len__ functions returning negative values with
1625 classic classes.
1626
1627- Patch #1538606, Fix __index__() clipping. There were some problems
1628 discovered with the API and how integers that didn't fit into Py_ssize_t
1629 were handled. This patch attempts to provide enough alternatives
1630 to effectively use __index__.
1631
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001632- Bug #1536021: __hash__ may now return long int; the final hash
1633 value is obtained by invoking hash on the long int.
1634
Thomas Hellerab1049c2006-08-08 17:37:00 +00001635- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1636
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001637- Bug #1535165: fixed a segfault in input() and raw_input() when
1638 sys.stdin is closed.
1639
Thomas Heller74d36f02006-08-04 18:17:40 +00001640- On Windows, the PyErr_Warn function is now exported from
1641 the Python dll again.
1642
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001643- Bug #1191458: tracing over for loops now produces a line event
1644 on each iteration. Fixing this problem required changing the .pyc
1645 magic number. This means that .pyc files generated before 2.5c1
1646 will be regenerated.
1647
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001648- Bug #1333982: string/number constants were inappropriately stored
1649 in the byte code and co_consts even if they were not used, ie
1650 immediately popped off the stack.
1651
Georg Brandle9462c72006-08-04 18:03:37 +00001652- Fixed a reference-counting problem in property().
1653
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001654
1655Library
1656-------
1657
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001658- Fix a bug in the ``compiler`` package that caused invalid code to be
1659 generated for generator expressions.
1660
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001661- The distutils version has been changed to 2.5.0. The change to
1662 keep it programmatically in sync with the Python version running
1663 the code (introduced in 2.5b3) has been reverted. It will continue
1664 to be maintained manually as static string literal.
1665
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001666- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001667 and this cannot be converted to the required C type, an exception is
1668 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001669 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001670
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001671- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001672 an exception.
1673
Tim Petersc10c9d02006-09-05 02:18:09 +00001674- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001675 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001676 workarounds for clocks with low resolution, to stop the code yielding
1677 duplicate UUIDs.
1678
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001679- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1680 before raising SystemExit, allowing IDLE to honor quit() and exit().
1681
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001682- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1683
Georg Brandl7a1af772006-08-14 21:55:28 +00001684- Patch #1536071: trace.py should now find the full module name of a
1685 file correctly even on Windows.
1686
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001687- logging's atexit hook now runs even if the rest of the module has
1688 already been cleaned up.
1689
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001690- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001691
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001692- Bug #1531405, format_exception no longer raises an exception if
1693 str(exception) raised an exception.
1694
Neil Schemenauer06ded092006-08-04 16:20:30 +00001695- Fix a bug in the ``compiler`` package that caused invalid code to be
1696 generated for nested functions.

1705 raises the correct exceptions.
1706
Thomas Heller1ce433e2006-08-14 16:20:04 +00001707- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1708 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1709
Thomas Heller86720042006-08-14 11:17:48 +00001710- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1711 uses the _as_parameter_ attribute when objects are passed to foreign
1712 function calls. The ctypes version number was changed to 1.0.1.
1713
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001714- Bug #1530559, struct.pack raises TypeError where it used to convert.
1715 Passing float arguments to struct.pack when integers are expected
1716 now triggers a DeprecationWarning.

1754
Tim Peters4643c2f2006-08-10 22:45:34 +00001755- Bug #1069160. Internal correctness changes were made to
1756 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1757 the documentation was changed to state that the return value
1758 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001761What's New in Python 2.5 beta 3?
1762================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001763
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001764*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001765
1766Core and builtins
1767-----------------
1768
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001769- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001770 returned a long (see PEP 353).
1771
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001772- Bug #1515471: string.replace() accepts character buffers again.
1773
Neal Norwitz07aadb12006-07-30 06:55:48 +00001774- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1775 This provides the proper warning for struct.pack().
1776 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1777
Neal Norwitz0d62a062006-07-30 06:53:31 +00001778- Patch #1531113: Fix augmented assignment with yield expressions.
1779 Also fix a SystemError when trying to assign to yield expressions.
1780
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001781- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1782 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1783 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1784 excessive filesystem operations during imports.
1785
Tim Petersbc24eee2006-07-27 01:14:53 +00001786- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1787 operations on signed longs that are formally undefined by C.
1788 Unfortunately, at least one compiler now cares about that, so complicated
1789 the code to make that compiler happy again.
1790
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001791- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1792
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001793- Patch #1232023: Stop including current directory in search
1794 path on Windows.
1795
Neal Norwitze1fdb322006-07-21 05:32:28 +00001796- Fix some potential crashes found with failmalloc.
1797
Neal Norwitze7563102006-07-17 01:00:16 +00001798- Fix warnings reported by Klocwork's static analysis tool.
1799
Neal Norwitz84be93b2006-07-16 01:50:38 +00001800- Bug #1512814, Fix incorrect lineno's when code within a function
1801 had more than 255 blank lines.
1802
Georg Brandl9dceedb2006-07-12 15:31:17 +00001803- Patch #1521179: Python now accepts the standard options ``--help`` and
1804 ``--version`` as well as ``/?`` on Windows.
1805
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001806- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001807 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001808 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001809
Tim Peters112aad32006-07-19 00:03:19 +00001810- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001811 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001812 new ``sys._current_frames()`` returns a dictionary with one entry,
1813 mapping the faux "thread id" 0 to the current frame.
1814
Ronald Oussoren3075e162006-07-25 20:28:55 +00001815- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001816

1819-------
1820
Facundo Batista6e22be72008-01-19 18:45:46 +00001821- Fix #1693149. Now you can pass several modules separated by
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00001822 comma to trace.py in the same --ignore-module option.
Facundo Batista6e22be72008-01-19 18:45:46 +00001823
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001824- Correction of patch #1455898: In the mbcs decoder, set final=False
1825 for stream decoder, but final=True for the decode function.
1826
Georg Brandl07fec3a2006-08-01 18:49:24 +00001827- os.urandom no longer masks unrelated exceptions like SystemExit or
1828 KeyboardInterrupt.
1829
Tim Peters4643c2f2006-08-10 22:45:34 +00001830- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001831 shutil.copytree on Windows
1832
Georg Brandle34ac7c2006-07-30 11:07:23 +00001833- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1834 refers to file descriptors, not file objects.
1835
Tim Petersc10c9d02006-09-05 02:18:09 +00001836- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001837 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001838 #1513611, and probably others.
1839
Georg Brandledd9b0d2006-07-29 09:33:26 +00001840- Bug #1441397: The compiler module now recognizes module and function
1841 docstrings correctly as it did in Python 2.4.
1842
Tim Peters6f681472006-07-27 23:44:37 +00001843- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1844 lost that tests are sorted by name before being run. This rarely
1845 matters for well-written tests, but can create baffling symptoms if
1846 side effects from one test to the next affect outcomes. ``DocTestFinder``
1847 has been changed to sort the list of tests it returns.
1848
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001849- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001850 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001851
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001852- Bug #978833: Really close underlying socket in _socketobject.close.
1853
Georg Brandl8c036cc2006-08-20 13:15:39 +00001854- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1855 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001856
Georg Brandlcf0c1722006-07-26 07:23:32 +00001857- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1858 to recursive calls and call it with the failing package name.
1859
Martin v. Löwis0b483032006-07-25 09:53:12 +00001860- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1861
Georg Brandlc13c34c2006-07-24 14:09:56 +00001862- Patch #1515343: Fix printing of deprecated string exceptions with a
1863 value in the traceback module.
1864
Greg Ward48fae7a2006-07-23 16:05:51 +00001865- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1866
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001867- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1868
Brett Cannoncaebe222006-07-18 04:41:36 +00001869- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1870 argument tuple. For arguments where zero is illegal, the value is forced to
1871 the minimum value that is correct. This is to support an undocumented but
1872 common way people used to fill in inconsequential information in the time
1873 tuple pre-2.4.
1874
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001875- Patch #1220874: Update the binhex module for Mach-O.
1876
Barry Warsawb110bad2006-07-21 14:51:07 +00001877- The email package has improved RFC 2231 support, specifically for
1878 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1879 (name*0=<blah>) parameter continuations. This may change the types of
1880 values returned from email.message.Message.get_param() and friends.
1881 Specifically in some cases where non-encoded continuations were used,
1882 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1883 will just return the string (since non-encoded continuations don't have
1884 charset and language parts).
1885
1886 Also, whereas % values were decoded in all parameter continuations, they are
1887 now only decoded in encoded parameter parts.
1888
Ronald Oussoren3075e162006-07-25 20:28:55 +00001889- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1890
1891- Bug #1517996: IDLE now longer shows the default Tk menu when a
1892 path browser, class browser or debugger is the frontmost window on MacOS X
1893
Barry Warsaw00decd72006-07-27 23:43:15 +00001894- Patch #1520294: Support for getset and member descriptors in types.py,
1895 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1896 of an object against these built-in types and more importantly, for getting
1897 their docstrings printed in the interactive interpreter's help() function.

1901-----------------
1902
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001903- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1904 a socket operation on a socket with a timeout, the exception will be
1905 caught correctly. Previously, the exception was not caught.
1906
Thomas Heller1393d6a2006-07-28 21:43:20 +00001907- Patch #1529514: The _ctypes extension is now compiled on more
1908 openbsd target platforms.
1909
Tim Peters9cab5932006-07-28 00:30:00 +00001910- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1911 a memory leak, affecting pickles and deep copies.
1912
Tim Petersbc24eee2006-07-27 01:14:53 +00001913- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1915
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001916- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1917
Thomas Hellerce049a02006-07-14 17:51:14 +00001918- Patch #1521817: Index range checking on ctypes arrays containing
1919 exactly one element enabled again. This allows iterating over these
1920 arrays, without the need to check the array size before.
1921
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001922- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001923 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001924 /dev/null in certain cases; this is now fixed.
1925
Thomas Heller47d7a062006-07-12 08:43:47 +00001926- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1927 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001928
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001929- Because of a misspelled preprocessor symbol, ctypes was always
1930 compiled without thread support; this is now fixed.
1931
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001932- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1933 methods now allow their database parameter to be None as the
1934 sleepycat API allows.
1935
Matt Flemingec926502006-07-28 11:27:27 +00001936- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1937 bluetooth API compared with Linux and FreeBSD.
1938
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001939Tests
1940-----
1941
1942- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1943 how long the test file should take to play. Now accepts taking 2.93 secs
1944 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1945
Georg Brandl4793aa32006-07-28 18:31:39 +00001946- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1947 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1948 run via ``regrtest.py``. Now they do.

1957
1958- PythonLauncher now works correctly when the path to the script contains
1959 characters that are treated specially by the shell (such as quotes).
1960
1961- Bug #1527397: PythonLauncher now launches scripts with the working directory
1962 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001963 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001964 expect.

Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001975- Bug #1441486: The literal representation of -(sys.maxint - 1)
1976 again evaluates to a int object, not a long.
1977
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001978- Bug #1501934: The scope of global variables that are locally assigned
1979 using augmented assignment is now correctly determined.

1985 and atof().
1986
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001987- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1988 omit a default "error" argument for NULL pointer. This allows
1989 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001990
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001991- Bug #1519018: 'as' is now validated properly in import statements.
1992
Neal Norwitz28746ab2006-07-09 22:14:42 +00001993- On 64 bit systems, int literals that use less than 64 bits are
1994 now ints rather than longs.
1995
Neal Norwitzed657552006-07-10 00:04:44 +00001996- Bug #1512814, Fix incorrect lineno's when code at module scope

Tim Peters32a83612006-07-10 21:08:24 +00001999- New function ``sys._current_frames()`` returns a dict mapping thread
2000 id to topmost thread stack frame. This is for expert use, and is
2001 especially useful for debugging application deadlocks. The functionality
2002 was previously available in Fazal Majid's ``threadframe`` extension
2003 module, but it wasn't possible to do this in a wholly threadsafe way from
2004 an extension.

2021
Thomas Woutersadd19112006-07-05 11:03:49 +00002022- string.Template() now correctly handles tuple-values. Previously,
2023 multi-value tuples would raise an exception and single-value tuples would
2024 be treated as the value they contain, instead.
2025
Martin v. Löwisede77f52006-07-03 13:01:35 +00002026- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

2051
Brett Cannon53ab5b72006-06-22 16:49:14 +00002052- Bug #1510580: The 'warnings' module improperly required that a Warning
2053 category be either a types.ClassType and a subclass of Warning. The proper
2054 check is just that it is a subclass with Warning as the documentation states.
2055
Georg Brandlad29e632006-06-21 17:45:17 +00002056- The compiler module now correctly compiles the new try-except-finally
2057 statement (bug #1509132).
2058
Neal Norwitz60373cd2006-06-22 06:30:50 +00002059- The wsgiref package is now installed properly on Unix.

Tim Peters112aad32006-07-19 00:03:19 +00002071- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
2072 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
2073 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00002074
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00002075- Assigning None to pointer type fields in ctypes structures possible
2076 overwrote the wrong fields, this is fixed now.
2077
2078- Fixed a segfault in _ctypes when ctypes.wintypes were imported
2079 on non-Windows platforms.
2080
2081- Bug #1518190: The ctypes.c_void_p constructor now accepts any
2082 integer or long, without range checking.
2083
2084- Patch #1517790: It is now possible to use custom objects in the ctypes
2085 foreign function argtypes sequence as long as they provide a from_param
2086 method, no longer is it required that the object is a ctypes type.
2087
2088- The '_ctypes' extension module now works when Python is configured
2089 with the --without-threads option.
2090
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00002091- Bug #1513646: os.access on Windows now correctly determines write
2092 access, again.
2093
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00002094- Bug #1512695: cPickle.loads could crash if it was interrupted with
2095 a KeyboardInterrupt.
2096
Neal Norwitza12aa882006-07-06 06:45:08 +00002097- Bug #1296433: parsing XML with a non-default encoding and

2106
Tim Peters32a83612006-07-10 21:08:24 +00002107- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00002108 Previously, the slight difference could cause compilation errors of the
2109 'zlib' module on systems with more than one version of zlib.
2110
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00002111- The MSI compileall step was fixed to also support a TARGETDIR

2143-----------------
2144
Georg Brandla56b9152006-06-19 06:35:54 +00002145- Patch #1507676: Error messages returned by invalid abstract object operations
2146 (such as iterating over an integer) have been improved and now include the
2147 type of the offending object to help with debugging.
2148
Brett Cannonea3912b2006-06-13 21:46:41 +00002149- Bug #992017: A classic class that defined a __coerce__() method that returned
2150 its arguments swapped would infinitely recurse and segfault the interpreter.
2151
Neal Norwitz909eb122006-06-12 02:13:21 +00002152- Fix the socket tests so they can be run concurrently.
2153
Neal Norwitzb9845e72006-06-12 02:11:18 +00002154- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00002155 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00002156
Brett Cannon22565aa2006-06-09 22:31:23 +00002157- Bug #532646: object.__call__() will continue looking for the __call__
2158 attribute on objects until one without one is found. This leads to recursion
2159 when you take a class and set its __call__ attribute to an instance of the
2160 class. Originally fixed for classic classes, but this fix is for new-style.
2161 Removes the infinite_rec_3 crasher.
2162
Georg Brandl24250812006-06-09 18:45:48 +00002163- The string and unicode methods startswith() and endswith() now accept
2164 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
2165
Brett Cannonde3b0522006-06-08 17:00:45 +00002166- Buffer objects, at the C level, never used the char buffer
2167 implementation even when the char buffer for the wrapped object was
2168 explicitly requested (originally returned the read or write buffer).
2169 Now a TypeError is raised if the char buffer is not present but is
2170 requested.
2171
Georg Brandlddbaa662006-06-04 21:56:52 +00002172- Patch #1346214: Statements like "if 0: suite" are now again optimized
2173 away like they were in Python 2.4.
2174
Georg Brandlb7c8f542006-05-27 12:30:25 +00002175- Builtin exceptions are now full-blown new-style classes instead of
2176 instances pretending to be classes, which speeds up exception handling
2177 by about 80% in comparison to 2.5a2.
2178
Martin v. Löwisd004fc82006-05-27 08:36:52 +00002179- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
2180 Unicode 4.1.
2181
Georg Brandlf4ef1162006-05-26 18:03:31 +00002182- Patch #921466: sys.path_importer_cache is now used to cache valid and
2183 invalid file paths for the built-in import machinery which leads to
2184 fewer open calls on startup.
2185
Tim Peters696cf432006-05-24 21:10:40 +00002186- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
2187 of-2 bases. The largest speedup is for inputs with about 1000 decimal
2188 digits. Conversion from non-power-of-2 bases remains quadratic-time in
2189 the number of input digits (it was and remains linear-time for bases
2190 2, 4, 8, 16 and 32).
2191
Tim Petersb713ec22006-05-23 18:45:30 +00002192- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
2193 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
2194 an integer close to ``sys.maxint``. This was repaired by patch
2195 #1335972, which also gives a nice speedup.
2196
Richard Jonescebbefc2006-05-23 18:28:17 +00002197- Patch #1337051: reduced size of frame objects.
2198
2199- PyErr_NewException now accepts a tuple of base classes as its
2200 "base" parameter.
2201
Richard Jones7c88dcc2006-05-23 10:37:38 +00002202- Patch #876206: function call speedup by retaining allocated frame
2203 objects.
2204
Georg Brandl7b90e162006-05-18 07:01:27 +00002205- Bug #1462152: file() now checks more thoroughly for invalid mode
2206 strings and removes a possible "U" before passing the mode to the
2207 C library function.
2208
Neal Norwitz1004a532006-05-15 07:17:23 +00002209- Patch #1488312, Fix memory alignment problem on SPARC in unicode
2210
Neal Norwitz373f0a72006-05-15 07:04:36 +00002211- Bug #1487966: Fix SystemError with conditional expression in assignment
2212
Martin v. Löwis879768d2006-05-11 13:28:43 +00002213- WindowsError now has two error code attributes: errno, which carries
2214 the error values from errno.h, and winerror, which carries the error
2215 values from winerror.h. Previous versions put the winerror.h values
2216 (from GetLastError()) into the errno attribute.
2217
Martin v. Löwis77736712006-05-04 05:51:03 +00002218- Patch #1475845: Raise IndentationError for unexpected indent.
2219
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00002220- Patch #1479181: split open() and file() from being aliases for each other.
2221
Tim Peters44bd9862006-06-01 13:49:23 +00002222- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
2223 methods were always silently ignored by dictionaries when comparing keys.
2224 They are now passed through (except when using the C API function
2225 ``PyDict_GetItem()``, whose semantics did not change).
2226
2227- Bug #1456209: In some obscure cases it was possible for a class with a
2228 custom ``__eq__()`` method to confuse dict internals when class instances
2229 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
2230 No, you don't have any code that did this ;-)

2238
Brett Cannon6ee7d012006-06-08 16:23:04 +00002239- Change binascii.hexlify to accept a read-only buffer instead of only a char
2240 buffer and actually follow its documentation.
2241
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00002242- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
2243
Nick Coghlanc649ec52006-05-29 12:43:05 +00002244- Patch #1478788 (modified version): The functional extension module has
2245 been renamed to _functools and a functools Python wrapper module added.
2246 This provides a home for additional function related utilities that are
2247 not specifically about functional programming. See PEP 309.
2248
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00002249- Patch #1493701: performance enhancements for struct module.

2254 copy() method.
2255
Andrew MacIntyre92913322006-06-13 15:04:24 +00002256- Patch #1454481: thread stack size is now tunable at runtime for thread
2257 enabled builds on Windows and systems with Posix threads support.
2258
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002259- On Win32, os.listdir now supports arbitrarily-long Unicode path names
2260 (up to the system limit of 32K characters).
2261
2262- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
2263 As a result, these functions now raise WindowsError instead of OSError.
2264
Tim Peters7a822da2006-05-25 21:50:17 +00002265- ``time.clock()`` on Win64 should use the high-performance Windows
2266 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
2267 Windows platforms).
2268
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002269- Calling Tk_Init twice is refused if the first call failed as that
2270 may deadlock.
2271
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00002272- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
2273 accept it without potentially using an uninitialized pointer.
2274
2275- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
2276 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
2277 patch numbers 1494885 and 1494902]

2286 results. It could previously incorrectly return 0 in some cases.
2287 Fixes SF bug 1493322 (pybsddb bug 1184012).
2288
Gregory P. Smithff7d9912006-06-08 05:17:08 +00002289- bsddb: the bsddb.dbtables Modify method now raises the proper error and

Gregory P. Smith506f7b52006-06-15 08:52:32 +00002293- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00002294 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002295 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
2296 database calls that would previously deadlock. [SF python bug #775414]

2320 mime.types file for determining MIME types.
2321
Georg Brandl2605ca82006-06-14 06:08:31 +00002322- Bug #1339007: Shelf objects now don't raise an exception in their
2323 __del__ method when initialization failed.
2324
Martin v. Löwisd8251432006-06-14 05:21:04 +00002325- Patch #1455898: The MBCS codec now supports the incremental mode for
2326 double-byte encodings.
2327
Tim Peters43898b42006-06-14 04:09:25 +00002328- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2329 guarantee that adjacent triples in the return list always describe
2330 non-adjacent blocks. Previously, a pair of matching blocks could end
2331 up being described by multiple adjacent triples that formed a partition
2332 of the matching pair.
2333
Greg Ward0e0c9f42006-06-11 16:24:11 +00002334- Bug #1498146: fix optparse to handle Unicode strings in option help,
2335 description, and epilog.
2336
Greg Wardd1c797e2006-06-11 14:42:41 +00002337- Bug #1366250: minor optparse documentation error.

2340 clarify docs.
2341
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002342- The wsgiref package has been added to the standard library.
2343
Nick Coghlan676725d2006-06-08 13:54:49 +00002344- The functions update_wrapper() and wraps() have been added to the functools
2345 module. These make it easier to copy relevant metadata from the original
2346 function when writing wrapper functions.
2347
Tim Petersd6a9eef2006-06-05 01:48:21 +00002348- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2349 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002350
Martin v. Löwis3f767792006-06-04 19:36:28 +00002351- Patch #1359618: Speed up charmap encoder by using a trie structure
2352 for lookup.
2353
Tim Petersd609b1a2006-06-02 23:22:51 +00002354- The functions in the ``pprint`` module now sort dictionaries by key
2355 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2356 if and only if its display required more than one line, although that
2357 wasn't documented. The new behavior increases predictability; e.g.,
2358 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2359
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002360- Patch #1497027: try HTTP digest auth before basic auth in urllib2

Georg Brandlb89316f2006-05-17 15:51:16 +00002370- Patch #1180296: Two new functions were added to the locale module:
2371 format_string() to get the effect of "format % items" but locale-aware,
2372 and currency() to format a monetary number with currency sign.

2378 tarfiles.
2379
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002380- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2381 stdout arguments, making it possible to redirect input and output
2382 for remote debugging.
2383
2384- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2385 a couple of issues, notably handling of long file names using the
2386 GNU LONGNAME extension.
2387
2388- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2389 new flag when ``name`` is already the name of an option flag.
2390
2391- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2392 package.
2393
2394- Patch #1472854: make the rlcompleter.Completer class usable on non-
2395 UNIX platforms.

2435Core and builtins
2436-----------------
2437
Thomas Heller1b046642006-04-18 18:51:06 +00002438- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2439 by converting these apis from macros into exported functions again:
2440
2441 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2442 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2443 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2444 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2445 PyRun_String Py_CompileString
2446
Martin v. Löwis45294a92006-04-18 06:24:08 +00002447- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2448
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002449- All uses of PyStructSequence_InitType have been changed to initialize
2450 the type objects only once, even if the interpreter is initialized
2451 multiple times.
2452
Neal Norwitz61546162006-04-14 05:20:28 +00002453- Bug #1454485, array.array('u') could crash the interpreter. This was
2454 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2455 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2456
2457- Py_UNICODE is unsigned. It was always documented as unsigned, but
2458 due to a bug had a signed value in previous versions.
2459
Tim Peters3a5e8b12006-04-11 01:44:07 +00002460- Patch #837242: ``id()`` of any Python object always gives a positive
2461 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2462 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002463 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002464 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002465
Tim Peters3a5e8b12006-04-11 01:44:07 +00002466 def __hash__(self):
2467 return id(self) # WRONG
2468
2469 because a hash result must be a (short) Python int but it was always
2470 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002471 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002472 was always usable as a hash value before this patch. That's no longer
2473 necessarily so.
2474
2475- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002476 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002477 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002478 #1454844)
2479
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002480- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2481 involving generators that have paused outside of any ``try`` or ``with``
2482 blocks. (In 2.5a1, a paused generator that was part of a reference
2483 cycle could not be garbage collected, regardless of whether it was
2484 paused in a ``try`` or ``with`` block.)

2504 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002505

Tim Peters711bf302006-04-25 03:31:36 +00002516- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2517 a doctest to be skipped (the code is not run, and the expected output
2518 or exception is ignored).
2519
Nick Coghlanda2268f2006-04-24 04:37:15 +00002520- Fixed contextlib.nested to cope with exceptions being raised and
2521 caught inside exit handlers.
2522
Greg Wardab05edc2006-04-23 03:47:58 +00002523- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2524 hex, octal, or binary; add ``append_const`` action; keep going if
2525 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2526 added ``epilog`` for better help generation).
2527
Tim Peters21fbd572006-04-21 21:18:10 +00002528- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2529 called from a thread spawned as a side effect of importing a module.
2530
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002531- The pydoc module now supports documenting packages contained in
2532 .zip or .egg files.
2533
2534- The pkgutil module now has several new utility functions, such
2535 as ``walk_packages()`` to support working with packages that are either
2536 in the filesystem or zip files.
2537
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002538- The mailbox module can now modify and delete messages from
2539 mailboxes, in addition to simply reading them. Thanks to Gregory
2540 K. Johnson for writing the code, and to the 2005 Google Summer of
2541 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002542
Tim Petersc7605f22006-04-17 21:12:33 +00002543- The ``__del__`` method of class ``local`` in module ``_threading_local``
2544 returned before accomplishing any of its intended cleanup.
2545
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002546- Patch #790710: Add breakpoint command lists in pdb.

Nick Coghlan27ec1a72006-04-24 04:32:47 +00002598- test_cmd_line now checks operation of the -m and -c command switches
2599
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002600- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2601 it separately and by hand. It also wasn't cleaning up its changes to
2602 the current Decimal context.
2603
Thomas Woutersabd08882006-04-26 15:53:30 +00002604- regrtest.py now has a -M option to run tests that test the new limits of
2605 containers, on 64-bit architectures. Running these tests is only sensible
2606 on 64-bit machines with more than two gigabytes of memory. The argument
2607 passed is the maximum amount of memory for the tests to use.

2616-------------
2617
Tim Petersb06d28c2006-05-12 01:57:59 +00002618- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2619
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002620- PEP 343: Added Context Types section to the library reference
2621 and attempted to bring other PEP 343 related documentation into
2622 line with the implementation and/or python-dev discussions.
2623
Tim Peters8dc73d22006-04-24 02:03:16 +00002624- Bug #1337990: clarified that ``doctest`` does not support examples
2625 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002628What's New in Python 2.5 alpha 1?
2629=================================
2630
Anthony Baxterebed3f62006-04-03 15:03:44 +00002631*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002632
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002633Core and builtins
2634-----------------
2635
Nick Coghlan43832302006-04-23 17:04:07 +00002636- PEP 338: -m command line switch now delegates to runpy.run_module
2637 allowing it to support modules in packages and zipfiles
2638
Martin v. Löwisc661b882006-04-20 04:54:23 +00002639- On Windows, .DLL is not an accepted file name extension for
2640 extension modules anymore; extensions are only found if they
2641 end in .PYD.
2642
Martin v. Löwisea62d252006-04-03 10:56:49 +00002643- Bug #1421664: sys.stderr.encoding is now set to the same value as
2644 sys.stdout.encoding.
2645
Neal Norwitz92e212f2006-04-03 04:48:37 +00002646- __import__ accepts keyword arguments.
2647
Georg Brandlccadf842006-03-31 18:54:53 +00002648- Patch #1460496: round() now accepts keyword arguments.
2649
Anthony Baxter262c00a2006-03-30 10:53:17 +00002650- Fixed bug #1459029 - unicode reprs were double-escaped.
2651
Hye-Shik Changd478f342006-03-23 12:32:36 +00002652- Patch #1396919: The system scope threads are reenabled on FreeBSD
2653 5.4 and later versions.
2654
Neal Norwitze98ccf62006-03-23 05:39:47 +00002655- Bug #1115379: Compiling a Unicode string with an encoding declaration
2656 now gives a SyntaxError.
2657
Georg Brandlabd1ff82006-03-18 07:59:59 +00002658- Previously, Python code had no easy way to access the contents of a
2659 cell object. Now, a ``cell_contents`` attribute has been added
2660 (closes patch #1170323).
2661
Tim Peterscf79aac2006-03-16 01:14:46 +00002662- Patch #1123430: Python's small-object allocator now returns an arena to
2663 the system ``free()`` when all memory within an arena becomes unused
2664 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2665 freed. Some applications will see a drop in virtual memory size now,
2666 especially long-running applications that, from time to time, temporarily
2667 use a large number of small objects. Note that when Python returns an
2668 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002669 platform C library will in turn return that memory to the operating system.
2670 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002671 appears to be effective at least on Microsoft C and gcc-based systems.
2672 Thanks to Evan Jones for hard work and patience.
2673
Georg Brandl533ff6f2006-03-08 18:09:27 +00002674- Patch #1434038: property() now uses the getter's docstring if there is
2675 no "doc" argument given. This makes it possible to legitimately use
2676 property() as a decorator to produce a read-only property.
2677
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002678- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2679 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2680 of requiring an int or long in slicing and a few other contexts, enabling
2681 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2682
Neal Norwitz995acdf2006-03-07 05:01:00 +00002683- Fixed various bugs reported by Coverity's Prevent tool.
2684
Brett Cannonbf364092006-03-01 04:25:17 +00002685- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2686 new exception base class, BaseException, which has a new message attribute.
2687 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2688 Raising a string exception now raises a DeprecationWarning.
2689
Thomas Woutersfb609f42006-02-28 16:37:25 +00002690- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2691 explicitly relative, using 'from .module import name' to mean 'from the same
2692 package as this module is in. Imports without dots still default to the
2693 old relative-then-absolute, unless 'from __future__ import
2694 absolute_import' is used.
2695
Brett Cannona7446e32006-02-27 23:39:10 +00002696- Properly check if 'warnings' raises an exception (usually when a filter set
2697 to "error" is triggered) when raising a warning for raising string
2698 exceptions.
2699
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002700- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002701 The name was removed from Include/code.h.
2702
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002703- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002704
Guido van Rossum1968ad32006-02-25 22:38:04 +00002705- Patch 1433928:
2706 - The copy module now "copies" function objects (as atomic objects).
2707 - dict.__getitem__ now looks for a __missing__ hook before raising
2708 KeyError.
2709
Tim Peters84ef21c2006-02-28 20:39:06 +00002710- PEP 343: with statement implemented. Needs ``from __future__ import
2711 with_statement``. Use of 'with' as a variable will generate a warning.
2712 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002713 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002714 The following objects have __context__ methods:
2715 - The built-in file type.
2716 - The thread.LockType type.
2717 - The following types defined by the threading module:
2718 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2719 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002720
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002721- Fix the encodings package codec search function to only search
2722 inside its own package. Fixes problem reported in patch #1433198.
2723
2724 Note: Codec packages should implement and register their own
2725 codec search function. PEP 100 has the details.
2726
Tim Peters9ea89d22006-06-04 03:26:02 +00002727- PEP 353: Using ``Py_ssize_t`` as the index type.
2728
2729- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2730 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2731 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2732 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2733 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002734
Neal Norwitzfc76d632006-01-10 06:03:13 +00002735- Patch #1400181, fix unicode string formatting to not use the locale.
2736 This is how string objects work. u'%f' could use , instead of .
2737 for the decimal point. Now both strings and unicode always use periods.
2738
Neal Norwitz671b9e32006-01-09 07:07:12 +00002739- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2740 configure would break checking curses.h.
2741
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002742- Bug #959576: The pwd module is now builtin. This allows Python to be
2743 built on UNIX platforms without $HOME set.
2744
Neal Norwitzc10978f2005-12-19 06:07:16 +00002745- Bug #1072182, fix some potential problems if characters are signed.
2746
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002747- Bug #889500, fix line number on SyntaxWarning for global declarations.
2748
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002749- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2750
Neal Norwitze7214a12005-12-18 05:03:17 +00002751- Support for converting hex strings to floats no longer works.
2752 This was not portable. float('0x3') now raises a ValueError.
2753
Barry Warsaw2a38a862005-12-18 01:27:35 +00002754- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002755 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002756 is now displayed in interactive prompt banner.
2757
Georg Brandlfa166682005-12-17 21:45:17 +00002758- Implementation of PEP 341 - Unification of try/except and try/finally.
2759 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002760 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002761
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002762- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2763 now encodes backslash correctly.
2764
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002765- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2766
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002767- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002768 and long longs.
2769
Neal Norwitz67715f02005-11-09 06:59:35 +00002770- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002771 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002772 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002773
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002774- Replaced most Unicode charmap codecs with new ones using the
2775 new Unicode translate string feature in the builtin charmap
2776 codec; the codecs were created from the mapping tables available
2777 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2778 encodings now include a mapping for the Apple logo)
2779
Tim Peterse3547fd2005-12-16 23:13:57 +00002780- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002781
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002782- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002783
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002784- A new AST parser implementation was completed. The abstract
2785 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002786 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002787
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002788- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002789 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2790
Neal Norwitz708e51a2005-10-03 04:48:15 +00002791- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2792
Neal Norwitz11bd1192005-10-03 00:54:56 +00002793- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2794 Provide a warning when a directory is passed on the command line.
2795
Neal Norwitz40d37812005-10-02 01:48:49 +00002796- Fix segfault with invalid coding.
2797
2798- SF bug #772896: unknown encoding results in MemoryError.
2799
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002800- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002801 supported a __len__() method which evaluated to False when the iterator
2802 was empty.
2803
Guido van Rossum630db602005-09-20 18:49:54 +00002804- On 64-bit platforms, when __len__() returns a value that cannot be
2805 represented as a C int, raise OverflowError.
2806
Skip Montanarof8948ca2005-09-19 03:54:46 +00002807- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002808 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002809
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002810- SF bug #893549: parsing keyword arguments was broken with a few format
2811 codes.
2812
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002813- Changes donated by Elemental Security to make it work on AIX 5.3
2814 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2815 bug #105470: test_pwd fails on 64bit system (Opteron).
2816
Guido van Rossum539c6622005-09-14 17:49:54 +00002817- Changes donated by Elemental Security to make it work on HP-UX 11 on
2818 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2819
Georg Brandl4550b8d2005-08-26 06:43:52 +00002820- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002821 (fixes bug #1119418).
2822
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002823- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2824
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002825- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2826 exceptions that cause a function to exit.
2827
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002828- The implementation of set() and frozenset() was revised to use its
2829 own internal data structure. Memory consumption is reduced by 1/3
2830 and there are modest speed-ups as well. The API is unchanged.
2831
Tim Petersde7990b2005-07-17 23:45:23 +00002832- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2833
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002834- SF bug #1229429: PyObject_CallMethod failed to decrement some
2835 reference counts in some error exit cases.
2836
Tim Petersecc6e6a2005-07-10 22:30:55 +00002837- SF bug #1185883: Python's small-object memory allocator took over
2838 a block managed by the platform C library whenever a realloc specified
2839 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002840 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002841 portable way to copy data from the C-managed block into Python's
2842 small-object space without risking a memory fault. Python's small-object
2843 realloc now leaves such blocks under the control of the platform C
2844 realloc.
2845
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002846- SF bug #1232517: An overflow error was not detected properly when
2847 attempting to convert a large float to an int in os.utime().
2848
Raymond Hettinger3296e692005-06-29 23:29:56 +00002849- SF bug #1224347: hex longs now print with lowercase letters just
2850 like their int counterparts.
2851
Michael W. Hudson188d4362005-06-20 16:52:57 +00002852- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2853 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2854 interpreter states; back out that fix and do a better job (see
2855 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2856 for a longer write-up of the problem).
2857
Michael W. Hudsondf888462005-06-03 14:41:55 +00002858- SF patch #1180995: marshal now uses a binary format by default when
2859 serializing floats.
2860
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002861- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2862 the routines that promise to produce IEEE 754 binary representations
2863 of floats now simply copy bytes around.
2864
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002865- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2866 278.

Brett Cannonc3647ac2005-04-26 03:45:26 +00002868- patch #1109424: int, long, float, complex, and unicode now check for the
2869 proper magic slot for type conversions when subclassed. Previously the
2870 magic slot was ignored during conversion. Semantics now match the way
2871 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002872 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002873 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002874 Thanks Walter D�rwald.

Barry Warsawc8d907c2005-04-19 23:43:40 +00002876- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2877 NULL, now raise an AttributeError when attempting to set or delete the
2878 attribute. Previously a TypeError was raised, but this was inconsistent
2879 with the equivalent pure-Python implementation.
2880
Michael W. Hudson774479c2005-04-18 08:46:17 +00002881- It is now safe to call PyGILState_Release() before
2882 PyEval_InitThreads() (note that if there is reason to believe there
2883 are multiple threads around you still must call PyEval_InitThreads()
2884 before using the Python API; this fix is for extension modules that
2885 have no way of knowing if Python is multi-threaded yet).
2886
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002887- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2888 disabled caused a crash.
2889
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002890- Bug #1165306: instancemethod_new allowed the creation of a method
2891 with im_class == im_self == NULL, which caused a crash when called.
2892
Tim Petersecc6e6a2005-07-10 22:30:55 +00002893- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002894 fixes the crash seen in bug #1165761
2895
Raymond Hettinger96229b12005-03-11 06:49:40 +00002896- Added two new builtins, any() and all().
2897
Brett Cannon409d8f22005-03-05 06:47:57 +00002898- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002899 (e.g., ``class C(): pass`` is no longer a syntax error).
2900 Patch #1176012 added support to the 'parser' module and 'compiler' package
2901 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002902

2904
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002905- Bug #1155938: new style classes did not check that __init__() was
2906 returning None.
2907
Tim Petersecc6e6a2005-07-10 22:30:55 +00002908- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002909 ('\') with a specific error message.
2910
Martin v. Löwisff232d72005-03-03 09:24:38 +00002911- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2912
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002913- Bug #1124295: the __name__ attribute of file objects was

2915
Tim Petersecc6e6a2005-07-10 22:30:55 +00002916- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002917 an ferror() call.
2918
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002919- min() and max() now support key= arguments with the same meaning as in
2920 list.sort().
2921
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002922- The peephole optimizer now performs simple constant folding in expressions:
2923 (2+3) --> (5).
2924
Raymond Hettingera422c342005-01-11 03:03:27 +00002925- set and frozenset objects can now be marshalled. SF #1098985.
2926
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002927- Bug #1077106: Poor argument checking could cause memory corruption
2928 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002929
Jeremy Hyltonab630502005-02-04 18:44:06 +00002930- The parser did not complain about future statements in illegal
2931 positions. It once again reports a syntax error if a future
2932 statement occurs after anything other than a doc string.
2933
Neil Schemenauercf52c072005-08-12 17:34:58 +00002934- Change the %s format specifier for str objects so that it returns a
2935 unicode instance if the argument is not an instance of basestring and
2936 calling __str__ on the argument returns a unicode instance.
2937
Tim Petersf4e69282006-02-27 17:15:31 +00002938- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2939 current thread state when the auto-GIL-state machinery knows about
2940 it (since the thread state is being deleted, continuing to remember it
2941 can't help, but can hurt if another thread happens to get created with
2942 the same thread id).

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00003134- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
3135 been renamed to have only a single underscore prefix. This was done to
3136 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003137
Nick Coghlan43832302006-04-23 17:04:07 +00003138- PEP 338: new module runpy defines a run_module function to support
3139 executing modules which provide access to source code or a code object
3140 via the PEP 302 import mechanisms.
3141
Anthony Baxter93f5b932006-04-03 08:05:07 +00003142- The email module's parsedate_tz function now sets the daylight savings
3143 flag to -1 (unknown) since it can't tell from the date whether it should
3144 be set.
3145

3150 in attribute values.
3151
Anthony Baxterc51ee692006-04-01 00:57:31 +00003152- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00003153 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00003154 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00003155 module will not be built.
3156
Tim Petersc17976e2006-04-01 00:26:53 +00003157- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
3158 aren't officially supported here, and trying to use them will probably
3159 raise an exception some day. But dicts have been allowed, and "mostly
3160 worked", so support for them won't go away without warning.
3161
Georg Brandl338ef7d2006-03-31 18:42:16 +00003162- Bug #1445068: getpass.getpass() can now be given an explicit stream
3163 argument to specify where to write the prompt.
3164
Georg Brandl22ec80b2006-03-31 18:25:44 +00003165- Patch #1462313, bug #1443328: the pickle modules now can handle classes

3171 key to be used for signing the uploaded code.
3172
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00003173- Queue.Queue objects now support .task_done() and .join() methods
3174 to make it easier to monitor when daemon threads have completed
3175 processing all enqueued tasks. Patch #1455676.
3176
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00003177- popen2.Popen objects now preserve the command in a .cmd attribute.
3178
Thomas Hellerc61c0492006-03-22 10:09:27 +00003179- Added the ctypes ffi package.
3180
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00003181- email 4.0 package now integrated. This is largely the same as the email 3.0
3182 package that was included in Python 2.3, except that PEP 8 module names are
3183 now used (e.g. mail.message instead of email.Message). The MIME classes
3184 have been moved to a subpackage (e.g. email.mime.text instead of
3185 email.MIMEText). The old names are still supported for now. Several
3186 deprecated Message methods have been removed and lots of bugs have been
3187 fixed. More details can be found in the email package documentation.
3188
Walter Dörwald40108c92006-03-27 08:15:44 +00003189- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
3190 (a subclass of tuple) that provides incremental decoders and encoders
3191 (a way to use stateful codecs without the stream API). Python functions
3192 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
3193 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
3194 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00003195
Walter Dörwald067db482006-03-15 22:17:27 +00003196- Patch #1359365: Calling next() on a closed StringIO.String object raises
3197 a ValueError instead of a StopIteration now (like file and cString.String do).
3198 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
3199 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00003200
Martin v. Löwis04824ce2006-03-10 21:26:16 +00003201- A regrtest option -w was added to re-run failed tests in verbose mode.

3204 interpreter to exit.
3205
Barry Warsawd3c38ff2006-03-07 09:46:03 +00003206- The function get_count() has been added to the gc module, and gc.collect()
3207 grew an optional 'generation' argument.
3208
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00003209- A library msilib to generate Windows Installer files, and a distutils

3213 and helpful context managers nested() and closing().
3214

Martin v. Löwis3e865952006-01-24 15:51:21 +00003249 specifications, raises IOErrors when proxies for unsupported protocols

3274 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
3275 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
3276 Ronald L. Rivest offered this advice for Python:
3277
3278 "The consensus of researchers in this area (at least as
3279 expressed at the NIST Hash Function Workshop 10/31/05),
3280 is that SHA-256 is a good choice for the time being, but
3281 that research should continue, and other alternatives may
3282 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00003283
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00003284- Added a subset of Fredrik Lundh's ElementTree package. Available

3395 files to PyPI.
3396
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00003397- distutils.commands.register now encodes the data as UTF-8 before posting
3398 them to PyPI.
3399
Raymond Hettinger267b8682005-03-27 10:47:39 +00003400- decimal operator and comparison methods now return NotImplemented
3401 instead of raising a TypeError when interacting with other types. This
3402 allows other classes to implement __radd__ style methods and have them
3403 work as expected.
3404
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003405- Bug #1163325: Decimal infinities failed to hash. Attempting to
3406 hash a NaN raised an InvalidOperation instead of a TypeError.
3407
Tim Petersecc6e6a2005-07-10 22:30:55 +00003408- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00003409 stream compression; add, for symmetry reasons, r:* as a synonym of r.
3410

Martin v. Löwisc72dd382005-03-04 13:50:17 +00003413- Patch #1075887: Don't require MSVC in distutils if there is nothing
3414 to build.
3415
Martin v. Löwis637431b2005-03-03 23:12:42 +00003416- Patch #1103407: Properly deal with tarfile iterators when untarring
3417 symbolic links on Windows.
3418
Tim Petersecc6e6a2005-07-10 22:30:55 +00003419- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00003420 profile.py if available.
3421
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00003422- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
3423
Martin v. Löwisc5574e82005-03-03 10:57:37 +00003424- Patch #1117454: Remove code to special-case cookies without values
3425 in LWPCookieJar.
3426
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00003427- Patch #1117339: Add cookielib special name tests.
3428

3430
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00003431- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
3432
Martin v. Löwisdf241532005-03-03 08:17:42 +00003433- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
3434
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00003435- Patch #1104111: Alter setup.py --help and --help-commands.
3436
Martin v. Löwis4afe1542005-03-01 08:09:28 +00003437- Patch #1121234: Properly cleanup _exit and tkerror commands.
3438
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00003439- Patch #1049151: xdrlib now unpacks booleans as True or False.
3440
Raymond Hettingerbab41432005-02-05 01:31:19 +00003441- Fixed bug in a NameError bug in cookielib. Patch #1116583.
3442
Guido van Rossumd0641422005-02-03 15:01:24 +00003443- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3444 disables recursive traversal through instance attributes, which can
3445 be exploited in various ways.
3446
Tim Peterse3547fd2005-12-16 23:13:57 +00003447- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003448 flags on the HTTP listening socket.
3449
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003450- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3451 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3452
Fred Drakefbdeaad2006-07-29 16:56:15 +00003453- Patches #893642, #1039083: add allow_none, encoding arguments to
3454 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003455

3457
Thomas Hellerd6c6e222005-01-20 19:20:16 +00003458- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3459
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003460- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3461
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003462- Enhancements to the csv module:
3463
3464 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003465 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003466 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003467 + Dialect parameter parsing has been re-implemented to improve error
3468 reporting.
3469 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3470 dictates.
3471 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003472 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003473 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003474 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3475 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003476 + reader now allows \r characters to be quoted (previously it only allowed
3477 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003478 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003479 + Dialect classes passed to the module are no longer instantiated by
3480 the module before being parsed (the former validation scheme required
3481 this, but the mechanism was unreliable).
3482 + The dialect registry now contains instances of the internal
3483 C-coded dialect type, rather than references to python objects.
3484 + the internal c-coded dialect type is now immutable.
3485 + register_dialect now accepts the same keyword dialect specifications
3486 as the reader and writer, allowing the user to register dialects
3487 without first creating a dialect class.
3488 + a configurable limit to the size of parsed fields has been added -
3489 previously, an unmatched quote character could result in the entire
3490 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003491 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003492 the parser field size limit (returning the former limit). The initial
3493 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003494 + A line_num attribute has been added to the reader object, which tracks
3495 the number of lines read from the source iterator. This is not
3496 the same as the number of records returned, as records can span
3497 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003498 + reader and writer objects were not being registered with the cyclic-GC.
3499 This has been fixed.
3500
Brett Cannone6539c42005-01-08 02:43:53 +00003501- _DummyThread objects in the threading module now delete self.__block that is
3502 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3503 lock primitives tend to be limited in number and thus should not be wasted on
3504 a _DummyThread object. Fixes bug #1089632.
3505
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003506- The imghdr module now detects Exif files.
3507
Raymond Hettinger6065d322004-12-20 23:51:53 +00003508- StringIO.truncate() now correctly adjusts the size attribute.
3509 (Bug #951915).
3510
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003511- locale.py now uses an updated locale alias table (built using
3512 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3513 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003514 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003515
Raymond Hettinger3557f422004-12-07 12:02:02 +00003516- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3517
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003518- the pickle module no longer accepts the deprecated None option in the
3519 args tuple returned by __reduce__().
3520
Brett Cannon84667c02004-12-07 03:25:18 +00003521- optparse now optionally imports gettext. This allows its use in setup.py.
3522
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003523- the pickle module no longer uses the deprecated bin parameter.
3524
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003525- the shelve module no longer uses the deprecated binary parameter.
3526
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003527- the pstats module no longer uses the deprecated ignore() method.
3528
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003529- the filecmp module no longer uses the deprecated use_statcache argument.
3530
Raymond Hettinger664347b2004-12-04 21:21:53 +00003531- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3532 extended or overridden by subclasses. Formerly, the subclassed method would
3533 be ignored by the rest of the module. (Bug #1078905).
3534
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003535- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003536 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003537
Walter Dörwald36733692004-12-22 12:50:50 +00003538- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3539 once when a size argument is given. This prevents a buffer overflow in the
3540 tokenizer with very long source lines.
3541
Barry Warsaw538561e2006-01-01 21:48:54 +00003542- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3543 immediately after creating the object, without any intervening
3544 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003545
Skip Montanaro05885812005-01-16 20:48:27 +00003546- The reconvert.quote function can now emit triple-quoted strings. The
3547 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003548
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003549- ``UserString.MutableString`` now supports negative indices in
3550 ``__setitem__`` and ``__delitem__``
3551
Greg Ward40407942005-03-05 02:53:17 +00003552- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3553 correctly.
3554
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003555- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3556 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3557 character even if the user has passed a size parameter to get a proper
3558 line ending. Remove the special handling of a "\r\n" that has been split
3559 between two lines.
3560
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003561- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3562 about illegal code points. The codec now supports PEP 293 style error
3563 handlers.
3564
Walter Dörwald78a78b02005-09-01 12:04:29 +00003565- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003566 from the input stream, so that the output is a byte string in the correct
3567 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003568
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003569- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3570 considering it exactly like a '*'.
3571
Walter Dörwald007f8df2005-10-09 19:42:27 +00003572- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3573 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003574
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003575- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3576
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003577- Patch #1413711: Certain patterns of differences were making difflib
3578 touch the recursion limit.
3579
Walter Dörwald58917a62006-03-31 15:26:22 +00003580- Bug #947906: An object oriented interface has been added to the calendar
3581 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003582 called as a script (e.g. via ``python -mcalendar``). Localized month and
3583 weekday names can be ouput (even if an exotic encoding is used) using
3584 special classes that use unicode.

3593
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003594- Build support for Win64-AMD64 was added.
3595
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003596- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3597
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003598- Patch #881820: look for openpty and forkpty also in libbsd.
3599
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003600- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3601 The zlib module is now builtin on Windows.
3602
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003603- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3604
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003605- Bug #1189330: configure did not correctly determine the necessary
3606 value of LINKCC if python was built with GCC 4.0.
3607
Trent Mick8321b422005-07-26 02:29:21 +00003608- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3609 vulnerability in zlib 1.2.1 and 1.2.2.
3610
Brett Cannon08cd5982005-04-24 22:26:38 +00003611- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3612 flags that change binary compatibility. Changes were also made to
3613 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003614 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003615
Bob Ippolitoed233462005-03-29 13:47:59 +00003616- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3617 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3618 no longer exists). This configure patch makes things right.
3619
Martin v. Löwise2713be2005-03-08 15:03:08 +00003620- Bug #1158607: Build with --disable-unicode again.
3621
Brett Cannon46d96232005-02-16 00:07:19 +00003622- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3623 defined. Discovered as a result of not being able to build on OS X.
3624
Brett Cannon516592f2004-12-07 00:42:59 +00003625- setup.py now uses the directories specified in LDFLAGS using the -L option
3626 and in CPPFLAGS using the -I option for adding library and include
3627 directories, respectively, for compiling extension modules against. This has
3628 led to the core being compiled using the values in CPPFLAGS. It also removes
3629 the need for the special-casing of both DarwinPorts and Fink for darwin since
3630 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3631 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3632 Fink, ``-I/opt/local/include`` for DarwinPorts).
3633
Brett Cannon43802422005-02-10 20:48:03 +00003634- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3635 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3636 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3637 Closes bug #1096244. Thanks Gregory Bond.

3640-----
3641
Tim Petersc9d78aa2006-03-26 23:27:58 +00003642- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3643 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3644 is obtained via the ``PyObject_`` family, it must be released via the
3645 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3646 always been officially true, but when Python's small-object allocator was
3647 introduced, an attempt was made to cater to a few extension modules
3648 discovered at the time that obtained memory via ``PyObject_New`` but
3649 released it via ``PyMem_DEL``. It's years later, and if such code still
3650 exists it will fail now (probably with segfaults, but calling wrong
3651 low-level memory management functions can yield many symptoms).
3652
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003653- Added a C API for set and frozenset objects.
3654
Raymond Hettinger66517482004-12-03 11:45:13 +00003655- Removed PyRange_New().
3656
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003657- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3658 mapping argument now. This string is used as a mapping table. Byte values
3659 greater than the length of the string and 0xFFFE are treated as undefined
3660 mappings.
