Nick Coghlanbb0996c2006-09-03 01:20:46 +00007What's New in Python 2.6 alpha 1?
8=================================
Martin v. Löwis2eb8c4f2006-08-18 03:47:18 +00009
Guido van Rossum901464f2007-12-08 04:38:23 +000010*Release date: XX-XXX-2008*
Neal Norwitz92422fb2006-08-18 03:57:54 +000011
12Core and builtins
13-----------------
14
Eric Smith7ef40bf2008-02-20 23:34:22 +000015- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
16 exponents for exponents with absolute value < 100. Follows C99
17 standard. This is a change on Windows, which would use 3 digits.
18 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
19 so that any alterations it does to the resulting string will be
20 available in stringlib/formatter.h (for float.__format__).
21
Eric Smith5a3c1352008-02-19 13:21:56 +000022- Implemented PEP 3101, Advanced String Formatting. This adds a new
23 builtin format(); a format() method for str and unicode; a
24 __format__() method to object, str, unicode, int, long, float, and
25 datetime; the class string.Formatter; and the C API
26 PyObject_Format().
27
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +000028- Fixed several potential crashes, all caused by specially crafted __del__
29 methods exploiting objects in temporarily inconsistent state.
30
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +000031- Issue #2115: Important speedup in setting __slot__ attributes. Also
32 prevent a possible crash: an Abstract Base Class would try to access a slot
33 on a registered virtual subclass.
34
Christian Heimes2f0da532008-02-15 06:57:08 +000035- Fixed repr() and str() of complex numbers with infinity or nan as real or
36 imaginary part.
37
Christian Heimes3b718a72008-02-14 12:47:33 +000038- Clear all free list during a gc.collect() of the highest generation in order
39 to allow pymalloc to free more arenas. Python may give back memory to the
40 OS earlier.
41
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +000042- Issue #2045: Fix an infinite recursion triggered when printing a subclass of
43 collections.defaultdict, if its default_factory is set to a bound method.
44
Christian Heimesf75dbef2008-02-08 00:11:31 +000045- Fixed a minor memory leak in dictobject.c. The content of the free
46 list was not freed on interpreter shutdown.
47
Christian Heimes6075a822008-02-06 12:44:34 +000048- Limit free list of method and builtin function objects to 256 entries
49 each.
50
Amaury Forgeot d'Arc578a8ca2008-02-04 20:53:14 +000051- Patch #1953: Added ``sys._compact_freelists()`` and the C API functions
52 ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +000053 to compact the internal free lists of pre-allocted ints and floats.
54
Christian Heimes951cc0f2008-01-31 23:08:23 +000055- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
56 Python expected the return type int but the fork familie returns pi_t.
57
Mark Dickinson105be772008-01-31 22:17:37 +000058- Issue #1678380: Fix a bug that identifies 0j and -0j when they appear
59 in the same code unit.
60
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +000061- Issue #2025 : Add tuple.count() and tuple.index() methods to comply with
62 the collections.Sequence API.
63
Christian Heimes4d4f2702008-01-30 11:32:37 +000064- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and linebreak
65 detection
66
Christian Heimes422051a2008-02-04 18:00:12 +000067- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear the
Christian Heimes908caac2008-01-27 23:34:59 +000068 internal lookup cache for ref leak tests.
69
Georg Brandl0cdf9a32008-01-26 14:14:20 +000070- Patch #1473257: generator objects gain a gi_code attribute. This is the
71 same object as the func_code attribute of the function that produced the
72 generator.
73
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +000074- Issue #1920: "while 0" statements were completely removed by the compiler,
75 even in the presence of an "else" clause, which is supposed to be run when
76 the condition is false. Now the compiler correctly emits bytecode for the
77 "else" suite.
78
Guido van Rossumeead05f2008-01-24 18:21:02 +000079- A few crashers fixed: weakref_in_del.py (issue #1377858);
80 loosing_dict_ref.py (issue #1303614, test67.py);
81 borrowed_ref_[34].py (not in tracker).
82
Vinay Sajipd7cf32e2008-01-24 12:43:33 +000083- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +000084 suppressed while an extension is loaded by calling SetErrorMode in
85 dynload_win.c. The error is still reported properly.
86
Christian Heimes082c9b02008-01-23 14:20:50 +000087- Bug #1915: Python compiles with --enable-unicode=no again. However
88 several extension methods and modules do not work without unicode
89 support.
90
Georg Brandl26543b12008-01-21 18:36:51 +000091- Issue #1882: when compiling code from a string, encoding cookies in the
92 second line of code were not always recognized correctly.
93
Georg Brandl14404b62008-01-19 19:27:05 +000094- Issue #1679: "0x" was taken as a valid integer literal.
95
Georg Brandl6caad7d2008-01-26 14:19:22 +000096- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +000097 added.
98
Christian Heimesc94e2b52008-01-14 04:13:37 +000099- sys.float_info / PyFloat_GetInfo: The floating point information
100 object was converted from a dict to a specialized structseq object.
101
Christian Heimesf31b69f2008-01-14 03:42:48 +0000102- Patch #1816: Added sys.flags structseq. It exposes the status of most
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000103 command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +0000104
Georg Brandl6caad7d2008-01-26 14:19:22 +0000105- Objects/structseq.c: Implemented new structseq representation. The patch
Christian Heimesf31b69f2008-01-14 03:42:48 +0000106 makes structseqs (e.g. the return value of os.stat) more readable.
Christian Heimes9c201962008-01-14 03:33:52 +0000107
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +0000108- Patch #1700288: added a type attribute cache that caches method accesses,
109 resulting in speedups in heavily object-oriented code.
110
Neal Norwitz3fc15b82008-01-10 05:42:58 +0000111- Bug #1776: __import__() no longer accepts filenames on any platform.
112 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +0000113
Georg Brandlaed6c662008-01-07 17:25:53 +0000114- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
115
Georg Brandl2da0fce2008-01-07 17:09:35 +0000116- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE envvar
117 and sys.dont_write_bytecode attribute. All these can be set to forbid Python
118 to attempt to write compiled bytecode files.
119
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +0000120- Improve some exception messages when Windows fails to load an extension
121 module. Now we get for example '%1 is not a valid Win32 application' instead
122 of 'error code 193'.
123
Christian Heimes8267d1d2008-01-04 00:37:34 +0000124- Bug #1481296: Fixed long(float('nan'))!=0L.
125
Christian Heimeseebb79c2008-01-03 22:32:26 +0000126- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x, y)
127 functions.
Christian Heimese2ca4242008-01-03 20:23:15 +0000128
Christian Heimes0a8143f2007-12-18 23:22:54 +0000129- Issue #1635: Platform independent creation and representation of NaN
130 and INF. float("nan"), float("inf") and float("-inf") now work on every
131 platform with IEEE 754 semantics.
132
Raymond Hettingerfd7ed402007-12-18 21:24:09 +0000133- Compiler now generates simpler and faster code for dictionary literals.
134 The oparg for BUILD_MAP now indicates an estimated dictionary size.
135 There is a new opcode, STORE_MAP, for adding entries to the dictionary.
136
Christian Heimesdb3d6cb2007-12-16 21:39:43 +0000137- Issue #1638: %zd configure test fails on Linux
138
Christian Heimes90e10e72007-12-14 02:35:23 +0000139- Issue #1620: New property decorator syntax was modifying the decorator
140 in place instead of creating a new decorator object.
141
Skip Montanaro26015492007-12-08 15:33:24 +0000142- Issue #1538: Avoid copying string in split/rsplit if the split
143 char is not found.
144
Andrew M. Kuchling395fe442007-12-05 13:27:20 +0000145- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +0000146 SystemError.
147
Nick Coghlanef01d822007-12-03 12:55:17 +0000148- PEP 366: Allow explicit relative imports when executing modules
149 inside packages with the -m switch via a new module level
150 __package__ attribute.
151
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +0000152- Issue #1402: Fix a crash on exit, when another thread is still running, and
153 if the deallocation of its frames somehow calls the PyGILState_Ensure() /
154 PyGILState_Release() functions.
155
Christian Heimes28104c52007-11-27 23:16:44 +0000156- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
157
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000158- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +0000159 attribute of an empty cell object.
160
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +0000161- Issue #1460: The utf-7 incremental decoder did not accept truncated input.
162 It now correctly saves its state between chunks of data.
163
Nick Coghlan327a39b2007-11-18 11:56:28 +0000164- Patch #1739468: Directories and zipfiles containing a __main__.py file can
165 now be directly executed by passing their name to the interpreter. The
166 directory/zipfile is automatically inserted as the first entry in sys.path.
167
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +0000168- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
169 generator expression when at the same time the executed code is closing a
170 paused generator.
171
Raymond Hettinger1760c8a2007-11-08 02:52:43 +0000172- sets and frozensets now have an isdisjoint() method.
173
Raymond Hettinger3f8caa32007-10-24 01:28:33 +0000174- optimize the performance of builtin.sum().
175
Neal Norwitz44f326e2007-10-05 05:29:17 +0000176- Fix warnings found by the new version of the Coverity checker.
177
Raymond Hettinger8f669372007-10-03 21:18:11 +0000178- The enumerate() builtin function is no longer bounded to sequences smaller
179 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
180 shifts from ints to longs.
181
Brett Cannon0b14f242007-09-30 19:45:10 +0000182- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
183 having a self-referential tuple, which is possible from C code. Nor did
184 object's tp_str consider that a type's tp_str could do something that could
185 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
186 respectively, fixed the issues.
187
Brett Cannon01531592007-09-17 03:28:34 +0000188- Issue #1164: It was possible to trigger deadlock when using the 'print'
189 statement to write to a file since the GIL was not released as needed. Now
190 PyObject_Print() does the right thing along with various tp_print
191 implementations of the built-in types and those in the collections module.
192
Brett Cannon4c20bc42007-09-11 21:02:28 +0000193- Issue #1147: Exceptions were directly allowing string exceptions in their
194 throw() method even though string exceptions no longer allowed.
195
Brett Cannona0c05512007-09-10 21:38:27 +0000196- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
197 list by using the recursion counter.
198
Brett Cannon1e534b52007-09-07 04:18:30 +0000199- Issue #1202533: Fix infinite recursion calls triggered by calls to
200 PyObject_Call() never calling back out to Python code to trigger recursion
201 depth updates/checks. Required the creation of a static RuntimeError
202 instance in case normalizing an exception put the recursion check value past
203 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
204
Martin v. Löwisa5136192007-09-04 14:19:28 +0000205- Patch #1031213: Decode source line in SyntaxErrors back to its original source
206 encoding.
207
Georg Brandl7c3b50d2007-07-12 08:38:00 +0000208- Patch #1673759: add a missing overflow check when formatting floats
209 with %G.
210
Neal Norwitzdb2b1b32007-06-11 07:36:24 +0000211- Prevent expandtabs() on string and unicode objects from causing a segfault
212 when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +0000213
Martin v. Löwisda587ab2007-06-08 17:29:20 +0000214- Bug #1733488: Fix compilation of bufferobject.c on AIX.
215
Georg Brandl25497a12007-06-01 19:20:27 +0000216- Bug #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +0000217
Neal Norwitz0ac60192007-05-27 04:08:54 +0000218- Add new attribute names for function objects. All the func_* become
219 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
220
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +0000221- Add -3 option to the interpreter to warn about features that are
222 deprecated and will be changed/removed in Python 3.0.
223
Georg Brandl2134e752007-05-21 20:34:16 +0000224- Patch #1686487: you can now pass any mapping after '**' in function
225 calls.
226
Collin Winter62903052007-05-18 23:11:24 +0000227- except clauses may now be spelled either "except E, target:" or
228 "except E as target:". This is to provide forwards compatibility with
229 Python 3.0.
230
Brett Cannon229cee22007-05-05 01:34:02 +0000231- Deprecate BaseException.message as per PEP 352.
232
Armin Rigo9790a272007-05-02 19:23:31 +0000233- Bug #1303614: don't expose object's __dict__ when the dict is
234 inherited from a builtin base.
235
Vinay Sajip8549ce32007-05-06 17:53:37 +0000236- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +0000237 setting a plain string, ie don't expand to single letter identifiers.
238
Raymond Hettinger13936692007-04-11 18:40:58 +0000239- Request #1191699: Slices can now be pickled.
240
Raymond Hettinger4db5fe92007-04-12 04:10:00 +0000241- Request #1193128: str.translate() now allows a None argument for
242 translations that only remove characters without re-mapping the
243 remaining characters.
244
Georg Brandl5cb76c12007-03-21 09:00:39 +0000245- Patch #1682205: a TypeError while unpacking an iterable is no longer
246 masked by a generic one with the message "unpack non-sequence".
247
Neal Norwitzaa754b72007-03-21 06:39:48 +0000248- Remove unused file Python/fmod.c.
249
Guido van Rossum143b5642007-03-23 04:58:42 +0000250- Bug #1683368: The object.__init__() and object.__new__() methods are
251 now stricter in rejecting excess arguments. The only time when
252 either allows excess arguments is when it is not overridden and the
253 other one is. For backwards compatibility, when both are
254 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +0000255 warning later). Also, type.__init__() insists on the same signature
256 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +0000257
Georg Brandl2b869942007-03-17 16:08:45 +0000258- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
259 to complex using its __complex__() method before falling back to the
260 __float__() method. Therefore, the functions in the cmath module now
261 can operate on objects that define a __complex__() method.
262
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +0000263- Patch #1623563: allow __class__ assignment for classes with __slots__.
264 The old and the new class are still required to have the same slot names.
265
Collin Winter77c67bd2007-03-16 04:11:30 +0000266- Patch #1642547: Fix an error/crash when encountering syntax errors in
267 complex if statements.
268
Žiga Seilnacht20f43d32007-03-15 11:44:55 +0000269- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
270 is called with an object that is faking its type.
271
Žiga Seilnacht71436f02007-03-14 12:24:09 +0000272- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
273 name.
274
Georg Brandl5240d742007-03-13 20:46:32 +0000275- Patch #1444529: the builtin compile() now accepts keyword arguments.
276
Georg Brandl7b9c5552007-03-12 14:30:05 +0000277- Bug #1678647: write a newline after printing an exception in any
278 case, even when converting the value to a string failed.
279
Georg Brandl871f1bc2007-03-12 13:17:36 +0000280- The dir() function has been extended to call the __dir__() method on
281 its argument, if it exists. If not, it will work like before. This allows
282 customizing the output of dir() in the presence of a __getattr__().
283
Collin Winter276887b2007-03-12 16:11:39 +0000284- Patch #922167: Python no longer segfaults when faced with infinitely
285 self-recursive reload() calls (as reported by bug #742342).
286
Žiga Seilnacht89032082007-03-11 15:54:54 +0000287- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
288
Collin Wintere38051d2007-03-09 20:33:07 +0000289- Patch #1491866: change the complex() constructor to allow parthensized
290 forms. This means complex(repr(x)) now works instead of raising a

877 and TestSuite subclasses (not instances) are no longer accepted in
878 TestSuite.addTest(). This should cause no incompatibility since it
879 never made sense with ordinary subclasses -- the failure just occurred
880 later, with a more cumbersome exception.

Vinay Sajip2bdc48c2008-01-21 18:16:05 +00001151- Issue829951: In the smtplib module, SMTP.starttls() now complies with
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00001152 RFC 3207 and forgets any knowledge obtained from the server not obtained
1153 from the TLS negotiation itself. Patch contributed by Bill Fenner.
1154
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00001155- Issue1339: The smtplib.SMTP class has been refactored a bit such
1156 that the SMTP.starttls() caller no longer needs to call ehlo()
1157 beforehand. SMTP.starttls() now raises an exception of the server
1158 does not claim to support starttls. Adds the SMTP.ehlo_or_helo_if_needed()
1159 method. Patch contributed by Bill Fenner.

1222 tuple, list, dict, set, and frozenset. Formerly, it would silently miscode
1223 subclasses of those types. Now, it raises a ValueError instead.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00001238- pybsddb.sf.net Bug #477182: Load the database flags at database open
1239 time so that opening a database previously created with the DB_DUP or
1240 DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
1241 Specifically: dictionary assignment to a DB object will replace all
1242 values for a given key when the database allows duplicate values.
1243 DB users should use DB.put(k, v) when they want to store duplicates; not
1244 DB[k] = v.
1245

1512 periodic threadstate and signal checking in tight loops. By default,
1513 this option is turned-off. It should only be enabled in debugged,
1514 performance critical applications.
1515
Martin v. Löwisd44a4e92007-09-05 11:47:34 +00001516- Patch #786737: Allow building in a tree of symlinks pointing to

Neal Norwitz92422fb2006-08-18 03:57:54 +00001561C API
1562-----
1563
Christian Heimes5b970ad2008-02-06 13:33:44 +00001564- Unified naming convention for free lists and their limits. All free lists
1565 in Object/ are named ``free_list``, the counter ``numfree`` and the upper
1566 limit is a macro ``PyName_MAXFREELIST`` inside an #ifndef block.
1567
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00001568- ``PySet_Add()`` can now modify a newly created frozenset. Similarly to
1569 ``PyTuple_SetItem``, it can be used to populate a brand new frozenset; but
1570 it does not steal a reference to the added item.
1571
1572- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
1573
Georg Brandl6caad7d2008-01-26 14:19:22 +00001574- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format and
1575 _FormatV from Python 3.0. Made PyLong_AsSsize_t and PyLong_FromSsize_t
1576 public functions.
1577
1578- Patch #1720595: add T_BOOL to the range of structmember types.
1579
1580- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
1581 ``PyFloat_GetInfo()`` to the float API.
1582
1583- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
1584 format code incorrectly truncated the length to an int, even when
1585 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
1586 results with huge strings.
1587
1588- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE
1589 and Py_REFCNT.
1590
1591- PEP 3123: Provide forward compatibility with Python 3.0, while keeping
1592 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
1593 PyVarObject_HEAD_INIT.
1594
1595- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
1596
1597- Patch #1733960: Allow T_LONGLONG to accept ints.
1598
1599- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
1600
Christian Heimes000a0742008-01-03 22:16:32 +00001601- Added a new API function ``PyImport_ImportModuleNoBlock``.
1602
Georg Brandl6caad7d2008-01-26 14:19:22 +00001603- Bug #1637022: Prefix AST symbols with _Py_.
1604
1605- Fix some leftovers from the conversion from int to Py_ssize_t
1606 (relevant to strings and sequences of more than 2**31 items).
1607
1608- Make _PyGILState_NoteThreadState() static, it was not used anywhere
1609 outside of pystate.c and should not be necessary.
1610
Christian Heimes000a0742008-01-03 22:16:32 +00001611- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do absolute
1612 imports. In earlier versions they might have used relative imports under
1613 some conditions.
1614
Andrew M. Kuchlingadc60ab2008-01-04 02:26:00 +00001615- Added case insensitive comparison methods ``PyOS_stricmp(char*, char*)``
Christian Heimes000a0742008-01-03 22:16:32 +00001616 and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
1617
Neal Norwitz8a267062006-08-19 04:25:29 +00001618- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx macro
1619 so it can be used as an expression.

Christian Heimes95d64472008-02-09 19:55:22 +00001625- Patch #1706: Drop support for Win9x, WinME and NT4. Python now requires
1626 Windows 2000 or greater. The _WINVER and NTDDI_VERSION macros are set to
1627 Win2k for x86/32bit builds and WinXP for AMD64 builds.
1628
Martin v. Löwis2607e6c2006-11-21 18:20:25 +00001629- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE
1630 and _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00001640- buildtools now raises a DeprecationWarning.
1641
Brett Cannon5e263512007-05-20 23:17:38 +00001642- Removed the macfs module. It had been deprecated since Python 2.5. This
1643 lead to the deprecation of macostools.touched() as it relied solely on macfs
1644 and was a no-op under OS X.

1654
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001655- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001656 compared equal or unequal to a string and a UnicodeDecodeError
1657 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001658
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001659 Instead, the equal (==) and unequal (!=) comparison operators will
1660 now issue a UnicodeWarning and interpret the two objects as
1661 unequal. The UnicodeWarning can be filtered as desired using
1662 the warning framework, e.g. silenced completely, turned into an
1663 exception, logged, etc.
1664
1665 Note that compare operators other than equal and unequal will still
1666 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001667
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001668- Fix segfault when doing string formatting on subclasses of long.
1669
1670- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1671 with new-style classes.
1672
1673- Fix bug related to __len__ functions returning negative values with
1674 classic classes.
1675
1676- Patch #1538606, Fix __index__() clipping. There were some problems
1677 discovered with the API and how integers that didn't fit into Py_ssize_t
1678 were handled. This patch attempts to provide enough alternatives
1679 to effectively use __index__.
1680
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001681- Bug #1536021: __hash__ may now return long int; the final hash
1682 value is obtained by invoking hash on the long int.
1683
Thomas Hellerab1049c2006-08-08 17:37:00 +00001684- Bug #1536786: buffer comparison could emit a RuntimeWarning.

Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001686- Bug #1535165: fixed a segfault in input() and raw_input() when
1687 sys.stdin is closed.
1688
Thomas Heller74d36f02006-08-04 18:17:40 +00001689- On Windows, the PyErr_Warn function is now exported from
1690 the Python dll again.
1691
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001692- Bug #1191458: tracing over for loops now produces a line event
1693 on each iteration. Fixing this problem required changing the .pyc
1694 magic number. This means that .pyc files generated before 2.5c1
1695 will be regenerated.
1696
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001697- Bug #1333982: string/number constants were inappropriately stored
1698 in the byte code and co_consts even if they were not used, ie
1699 immediately popped off the stack.
1700
Georg Brandle9462c72006-08-04 18:03:37 +00001701- Fixed a reference-counting problem in property().

1708 generated for generator expressions.
1709
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001710- The distutils version has been changed to 2.5.0. The change to
1711 keep it programmatically in sync with the Python version running
1712 the code (introduced in 2.5b3) has been reverted. It will continue
1713 to be maintained manually as static string literal.
1714
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001715- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001716 and this cannot be converted to the required C type, an exception is
1717 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001718 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001719
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001720- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001721 an exception.
1722
Tim Petersc10c9d02006-09-05 02:18:09 +00001723- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001724 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001725 workarounds for clocks with low resolution, to stop the code yielding
1726 duplicate UUIDs.
1727
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001728- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1729 before raising SystemExit, allowing IDLE to honor quit() and exit().
1730
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001731- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

Georg Brandl7a1af772006-08-14 21:55:28 +00001733- Patch #1536071: trace.py should now find the full module name of a
1734 file correctly even on Windows.
1735
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001736- logging's atexit hook now runs even if the rest of the module has
1737 already been cleaned up.
1738
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001739- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001740
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001741- Bug #1531405, format_exception no longer raises an exception if
1742 str(exception) raised an exception.
1743
Neil Schemenauer06ded092006-08-04 16:20:30 +00001744- Fix a bug in the ``compiler`` package that caused invalid code to be
1745 generated for nested functions.

1752
Georg Brandl3335a7a2006-08-14 21:42:55 +00001753- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1754 raises the correct exceptions.
1755
Thomas Heller1ce433e2006-08-14 16:20:04 +00001756- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1757 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1758
Thomas Heller86720042006-08-14 11:17:48 +00001759- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1760 uses the _as_parameter_ attribute when objects are passed to foreign
1761 function calls. The ctypes version number was changed to 1.0.1.
1762
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001763- Bug #1530559, struct.pack raises TypeError where it used to convert.
1764 Passing float arguments to struct.pack when integers are expected
1765 now triggers a DeprecationWarning.
1766
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001767
1768Tests
1769-----
1770
Neal Norwitzb476fdf2006-08-15 04:58:28 +00001771- test_socketserver should now work on cygwin and not fail sporadically
1772 on other platforms.

1777
Andrew MacIntyre16ee33a2006-08-06 12:37:03 +00001778- test_threading now skips testing alternate thread stack sizes on
1779 platforms that don't support changing thread stack size.
1780
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001781
Georg Brandl212b5872006-08-05 06:10:54 +00001782Documentation
1783-------------

1789-----
1790
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001791- Bug #1535502, build _hashlib on Windows, and use masm assembler
1792 code in OpenSSL.
1793
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001794- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Thomas Heller17984892006-08-04 18:57:34 +00001797
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001798
Tim Peters4643c2f2006-08-10 22:45:34 +00001799C API
1800-----
1801
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001802- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1803
Tim Peters4643c2f2006-08-10 22:45:34 +00001804- Bug #1069160. Internal correctness changes were made to
1805 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1806 the documentation was changed to state that the return value
1807 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001810What's New in Python 2.5 beta 3?
1811================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001812
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001813*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001814
1815Core and builtins
1816-----------------
1817
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001818- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001819 returned a long (see PEP 353).
1820
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001821- Bug #1515471: string.replace() accepts character buffers again.
1822
Neal Norwitz07aadb12006-07-30 06:55:48 +00001823- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1824 This provides the proper warning for struct.pack().
1825 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1826
Neal Norwitz0d62a062006-07-30 06:53:31 +00001827- Patch #1531113: Fix augmented assignment with yield expressions.
1828 Also fix a SystemError when trying to assign to yield expressions.
1829
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001830- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1831 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1832 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1833 excessive filesystem operations during imports.
1834
Tim Petersbc24eee2006-07-27 01:14:53 +00001835- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1836 operations on signed longs that are formally undefined by C.
1837 Unfortunately, at least one compiler now cares about that, so complicated
1838 the code to make that compiler happy again.
1839
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001840- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1841
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001842- Patch #1232023: Stop including current directory in search
1843 path on Windows.
1844
Neal Norwitze1fdb322006-07-21 05:32:28 +00001845- Fix some potential crashes found with failmalloc.
1846
Neal Norwitze7563102006-07-17 01:00:16 +00001847- Fix warnings reported by Klocwork's static analysis tool.
1848
Neal Norwitz84be93b2006-07-16 01:50:38 +00001849- Bug #1512814, Fix incorrect lineno's when code within a function
1850 had more than 255 blank lines.
1851
Georg Brandl9dceedb2006-07-12 15:31:17 +00001852- Patch #1521179: Python now accepts the standard options ``--help`` and
1853 ``--version`` as well as ``/?`` on Windows.
1854
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001855- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001856 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001857 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001858
Tim Peters112aad32006-07-19 00:03:19 +00001859- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001860 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001861 new ``sys._current_frames()`` returns a dictionary with one entry,
1862 mapping the faux "thread id" 0 to the current frame.
1863
Ronald Oussoren3075e162006-07-25 20:28:55 +00001864- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001865
Ronald Oussoren3075e162006-07-25 20:28:55 +00001866
Neal Norwitza1f10902006-07-12 07:28:29 +00001867Library
1868-------
1869
Facundo Batista6e22be72008-01-19 18:45:46 +00001870- Fix #1693149. Now you can pass several modules separated by
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00001871 comma to trace.py in the same --ignore-module option.
Facundo Batista6e22be72008-01-19 18:45:46 +00001872
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001873- Correction of patch #1455898: In the mbcs decoder, set final=False
1874 for stream decoder, but final=True for the decode function.
1875
Georg Brandl07fec3a2006-08-01 18:49:24 +00001876- os.urandom no longer masks unrelated exceptions like SystemExit or
1877 KeyboardInterrupt.
1878
Tim Peters4643c2f2006-08-10 22:45:34 +00001879- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001880 shutil.copytree on Windows
1881
Georg Brandle34ac7c2006-07-30 11:07:23 +00001882- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1883 refers to file descriptors, not file objects.
1884
Tim Petersc10c9d02006-09-05 02:18:09 +00001885- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001886 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001887 #1513611, and probably others.
1888
Georg Brandledd9b0d2006-07-29 09:33:26 +00001889- Bug #1441397: The compiler module now recognizes module and function
1890 docstrings correctly as it did in Python 2.4.
1891
Tim Peters6f681472006-07-27 23:44:37 +00001892- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1893 lost that tests are sorted by name before being run. This rarely
1894 matters for well-written tests, but can create baffling symptoms if
1895 side effects from one test to the next affect outcomes. ``DocTestFinder``
1896 has been changed to sort the list of tests it returns.
1897
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001898- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001899 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001900
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001901- Bug #978833: Really close underlying socket in _socketobject.close.
1902
Georg Brandl8c036cc2006-08-20 13:15:39 +00001903- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1904 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001905
Georg Brandlcf0c1722006-07-26 07:23:32 +00001906- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1907 to recursive calls and call it with the failing package name.
1908
Martin v. Löwis0b483032006-07-25 09:53:12 +00001909- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1910
Georg Brandlc13c34c2006-07-24 14:09:56 +00001911- Patch #1515343: Fix printing of deprecated string exceptions with a
1912 value in the traceback module.
1913
Greg Ward48fae7a2006-07-23 16:05:51 +00001914- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1915
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001916- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1917
Brett Cannoncaebe222006-07-18 04:41:36 +00001918- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1919 argument tuple. For arguments where zero is illegal, the value is forced to
1920 the minimum value that is correct. This is to support an undocumented but
1921 common way people used to fill in inconsequential information in the time
1922 tuple pre-2.4.
1923
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001924- Patch #1220874: Update the binhex module for Mach-O.
1925
Barry Warsawb110bad2006-07-21 14:51:07 +00001926- The email package has improved RFC 2231 support, specifically for
1927 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1928 (name*0=<blah>) parameter continuations. This may change the types of
1929 values returned from email.message.Message.get_param() and friends.
1930 Specifically in some cases where non-encoded continuations were used,
1931 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1932 will just return the string (since non-encoded continuations don't have
1933 charset and language parts).
1934
1935 Also, whereas % values were decoded in all parameter continuations, they are
1936 now only decoded in encoded parameter parts.
1937
Ronald Oussoren3075e162006-07-25 20:28:55 +00001938- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1939
1940- Bug #1517996: IDLE now longer shows the default Tk menu when a
1941 path browser, class browser or debugger is the frontmost window on MacOS X
1942
Barry Warsaw00decd72006-07-27 23:43:15 +00001943- Patch #1520294: Support for getset and member descriptors in types.py,
1944 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1945 of an object against these built-in types and more importantly, for getting
1946 their docstrings printed in the interactive interpreter's help() function.
1947
Ronald Oussoren3075e162006-07-25 20:28:55 +00001948

1950-----------------
1951
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001952- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1953 a socket operation on a socket with a timeout, the exception will be
1954 caught correctly. Previously, the exception was not caught.
1955
Thomas Heller1393d6a2006-07-28 21:43:20 +00001956- Patch #1529514: The _ctypes extension is now compiled on more
1957 openbsd target platforms.
1958
Tim Peters9cab5932006-07-28 00:30:00 +00001959- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1960 a memory leak, affecting pickles and deep copies.
1961
Tim Petersbc24eee2006-07-27 01:14:53 +00001962- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1964
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001965- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1966
Thomas Hellerce049a02006-07-14 17:51:14 +00001967- Patch #1521817: Index range checking on ctypes arrays containing
1968 exactly one element enabled again. This allows iterating over these
1969 arrays, without the need to check the array size before.
1970
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001971- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001972 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001973 /dev/null in certain cases; this is now fixed.
1974
Thomas Heller47d7a062006-07-12 08:43:47 +00001975- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1976 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001977
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001978- Because of a misspelled preprocessor symbol, ctypes was always
1979 compiled without thread support; this is now fixed.
1980
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001981- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1982 methods now allow their database parameter to be None as the
1983 sleepycat API allows.
1984
Matt Flemingec926502006-07-28 11:27:27 +00001985- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1986 bluetooth API compared with Linux and FreeBSD.
1987
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001988Tests
1989-----
1990
1991- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1992 how long the test file should take to play. Now accepts taking 2.93 secs
1993 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1994
Georg Brandl4793aa32006-07-28 18:31:39 +00001995- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1996 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when

2006
2007- PythonLauncher now works correctly when the path to the script contains
2008 characters that are treated specially by the shell (such as quotes).
2009
2010- Bug #1527397: PythonLauncher now launches scripts with the working directory
2011 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00002012 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00002013 expect.

2021Core and builtins
2022-----------------
2023
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00002024- Bug #1441486: The literal representation of -(sys.maxint - 1)
2025 again evaluates to a int object, not a long.
2026
Neil Schemenauer0e07b602006-07-09 16:16:34 +00002027- Bug #1501934: The scope of global variables that are locally assigned
2028 using augmented assignment is now correctly determined.
2029
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00002030- Bug #927248: Recursive method-wrapper objects can now safely
2031 be released.
2032
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00002033- Bug #1417699: Reject locale-specific decimal point in float()
2034 and atof().
2035
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00002036- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
2037 omit a default "error" argument for NULL pointer. This allows
2038 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00002039
Neal Norwitzfb48afa2006-07-08 05:31:37 +00002040- Bug #1519018: 'as' is now validated properly in import statements.
2041
Neal Norwitz28746ab2006-07-09 22:14:42 +00002042- On 64 bit systems, int literals that use less than 64 bits are
2043 now ints rather than longs.
2044
Neal Norwitzed657552006-07-10 00:04:44 +00002045- Bug #1512814, Fix incorrect lineno's when code at module scope
2046 started after line 256.
2047
Tim Peters32a83612006-07-10 21:08:24 +00002048- New function ``sys._current_frames()`` returns a dict mapping thread
2049 id to topmost thread stack frame. This is for expert use, and is
2050 especially useful for debugging application deadlocks. The functionality
2051 was previously available in Fazal Majid's ``threadframe`` extension
2052 module, but it wasn't possible to do this in a wholly threadsafe way from
2053 an extension.

2062
Tim Peters32a83612006-07-10 21:08:24 +00002063- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00002064 environment variable to be set in order to the SDK environment
2065 for finding the compiler, include files, etc.

2070
Thomas Woutersadd19112006-07-05 11:03:49 +00002071- string.Template() now correctly handles tuple-values. Previously,
2072 multi-value tuples would raise an exception and single-value tuples would
2073 be treated as the value they contain, instead.
2074
Martin v. Löwisede77f52006-07-03 13:01:35 +00002075- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

2082 degrees and radians.
2083
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00002084- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00002085 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00002086
Martin v. Löwisbd39c032006-07-03 09:44:00 +00002087- Bug #1514703: Only setup canvas window in turtle when the canvas
2088 is created.
2089
Martin v. Löwis7596e832006-07-01 15:33:37 +00002090- Bug #1513223: .close() of a _socketobj now releases the underlying

2094 attribute values.
2095
2096- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
2097 sgmllib ('[' and ']' were not accepted).
2098
Georg Brandl1be63af2006-06-28 20:23:25 +00002099- Fix a bug in the turtle module's end_fill function.
2100
Brett Cannon53ab5b72006-06-22 16:49:14 +00002101- Bug #1510580: The 'warnings' module improperly required that a Warning
2102 category be either a types.ClassType and a subclass of Warning. The proper
2103 check is just that it is a subclass with Warning as the documentation states.
2104
Georg Brandlad29e632006-06-21 17:45:17 +00002105- The compiler module now correctly compiles the new try-except-finally
2106 statement (bug #1509132).
2107
Neal Norwitz60373cd2006-06-22 06:30:50 +00002108- The wsgiref package is now installed properly on Unix.
2109
Vinay Sajip28e57612006-07-01 10:45:20 +00002110- A bug was fixed in logging.config.fileConfig() which caused a crash on
2111 shutdown when fileConfig() was called multiple times.
2112
Gerhard Häring762fbd32006-07-02 17:48:30 +00002113- The sqlite3 module did cut off data from the SQLite database at the first
2114 null character before sending it to a custom converter. This has been fixed
2115 now.
2116
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00002117Extension Modules
2118-----------------
2119
Tim Peters112aad32006-07-19 00:03:19 +00002120- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
2121 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
2122 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00002123
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00002124- Assigning None to pointer type fields in ctypes structures possible
2125 overwrote the wrong fields, this is fixed now.
2126
2127- Fixed a segfault in _ctypes when ctypes.wintypes were imported
2128 on non-Windows platforms.
2129
2130- Bug #1518190: The ctypes.c_void_p constructor now accepts any
2131 integer or long, without range checking.
2132
2133- Patch #1517790: It is now possible to use custom objects in the ctypes
2134 foreign function argtypes sequence as long as they provide a from_param
2135 method, no longer is it required that the object is a ctypes type.
2136
2137- The '_ctypes' extension module now works when Python is configured
2138 with the --without-threads option.
2139
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00002140- Bug #1513646: os.access on Windows now correctly determines write
2141 access, again.
2142
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00002143- Bug #1512695: cPickle.loads could crash if it was interrupted with
2144 a KeyboardInterrupt.
2145
Neal Norwitza12aa882006-07-06 06:45:08 +00002146- Bug #1296433: parsing XML with a non-default encoding and
2147 a CharacterDataHandler could crash the interpreter in pyexpat.
2148
Neal Norwitz2a30cd02006-07-10 01:18:57 +00002149- Patch #1516912: improve Modules support for OpenVMS.

Neal Norwitz3b6b8012006-06-27 04:12:58 +00002151Build
2152-----
2153
Martin v. Löwisd73168d2006-07-14 09:58:55 +00002154- Automate Windows build process for the Win64 SSL module.
2155
Tim Peters32a83612006-07-10 21:08:24 +00002156- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00002157 Previously, the slight difference could cause compilation errors of the
2158 'zlib' module on systems with more than one version of zlib.
2159
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00002160- The MSI compileall step was fixed to also support a TARGETDIR
2161 with spaces in it.
2162
Martin v. Löwis88ef6372006-07-06 06:55:58 +00002163- Bug #1517388: sqlite3.dll is now installed on Windows independent
2164 of Tcl/Tk.
2165
Neal Norwitzc315a0f2006-06-27 04:28:56 +00002166- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00002167 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +00002169Tests
2170-----
2171
2172- Call os.waitpid() at the end of tests that spawn child processes in order
2173 to minimize resources (zombies).
2174
Martin v. Löwis1bf59592006-06-29 18:58:44 +00002175Documentation
2176-------------
2177
Nick Coghlan2d792252006-07-06 13:47:18 +00002178- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
2179 documentation for the warnings module.
2180
Martin v. Löwis1bf59592006-06-29 18:58:44 +00002181- Patch #1509163: MS Toolkit Compiler no longer available.
2182

Anthony Baxter51bcb682006-04-05 14:51:42 +00002190
2191Core and builtins
2192-----------------
2193
Georg Brandla56b9152006-06-19 06:35:54 +00002194- Patch #1507676: Error messages returned by invalid abstract object operations
2195 (such as iterating over an integer) have been improved and now include the
2196 type of the offending object to help with debugging.
2197
Brett Cannonea3912b2006-06-13 21:46:41 +00002198- Bug #992017: A classic class that defined a __coerce__() method that returned
2199 its arguments swapped would infinitely recurse and segfault the interpreter.
2200
Neal Norwitz909eb122006-06-12 02:13:21 +00002201- Fix the socket tests so they can be run concurrently.
2202
Neal Norwitzb9845e72006-06-12 02:11:18 +00002203- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00002204 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00002205
Brett Cannon22565aa2006-06-09 22:31:23 +00002206- Bug #532646: object.__call__() will continue looking for the __call__
2207 attribute on objects until one without one is found. This leads to recursion
2208 when you take a class and set its __call__ attribute to an instance of the
2209 class. Originally fixed for classic classes, but this fix is for new-style.
2210 Removes the infinite_rec_3 crasher.
2211
Georg Brandl24250812006-06-09 18:45:48 +00002212- The string and unicode methods startswith() and endswith() now accept
2213 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
2214
Brett Cannonde3b0522006-06-08 17:00:45 +00002215- Buffer objects, at the C level, never used the char buffer
2216 implementation even when the char buffer for the wrapped object was
2217 explicitly requested (originally returned the read or write buffer).
2218 Now a TypeError is raised if the char buffer is not present but is
2219 requested.
2220
Georg Brandlddbaa662006-06-04 21:56:52 +00002221- Patch #1346214: Statements like "if 0: suite" are now again optimized
2222 away like they were in Python 2.4.
2223
Georg Brandlb7c8f542006-05-27 12:30:25 +00002224- Builtin exceptions are now full-blown new-style classes instead of
2225 instances pretending to be classes, which speeds up exception handling
2226 by about 80% in comparison to 2.5a2.
2227
Martin v. Löwisd004fc82006-05-27 08:36:52 +00002228- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
2229 Unicode 4.1.
2230
Georg Brandlf4ef1162006-05-26 18:03:31 +00002231- Patch #921466: sys.path_importer_cache is now used to cache valid and
2232 invalid file paths for the built-in import machinery which leads to
2233 fewer open calls on startup.
2234
Tim Peters696cf432006-05-24 21:10:40 +00002235- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
2236 of-2 bases. The largest speedup is for inputs with about 1000 decimal
2237 digits. Conversion from non-power-of-2 bases remains quadratic-time in
2238 the number of input digits (it was and remains linear-time for bases
2239 2, 4, 8, 16 and 32).
2240
Tim Petersb713ec22006-05-23 18:45:30 +00002241- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
2242 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
2243 an integer close to ``sys.maxint``. This was repaired by patch
2244 #1335972, which also gives a nice speedup.
2245
Richard Jonescebbefc2006-05-23 18:28:17 +00002246- Patch #1337051: reduced size of frame objects.
2247
2248- PyErr_NewException now accepts a tuple of base classes as its
2249 "base" parameter.
2250
Richard Jones7c88dcc2006-05-23 10:37:38 +00002251- Patch #876206: function call speedup by retaining allocated frame
2252 objects.
2253
Georg Brandl7b90e162006-05-18 07:01:27 +00002254- Bug #1462152: file() now checks more thoroughly for invalid mode
2255 strings and removes a possible "U" before passing the mode to the
2256 C library function.
2257
Neal Norwitz1004a532006-05-15 07:17:23 +00002258- Patch #1488312, Fix memory alignment problem on SPARC in unicode
2259
Neal Norwitz373f0a72006-05-15 07:04:36 +00002260- Bug #1487966: Fix SystemError with conditional expression in assignment
2261
Martin v. Löwis879768d2006-05-11 13:28:43 +00002262- WindowsError now has two error code attributes: errno, which carries
2263 the error values from errno.h, and winerror, which carries the error
2264 values from winerror.h. Previous versions put the winerror.h values
2265 (from GetLastError()) into the errno attribute.
2266
Martin v. Löwis77736712006-05-04 05:51:03 +00002267- Patch #1475845: Raise IndentationError for unexpected indent.
2268
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00002269- Patch #1479181: split open() and file() from being aliases for each other.
2270
Tim Peters44bd9862006-06-01 13:49:23 +00002271- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
2272 methods were always silently ignored by dictionaries when comparing keys.
2273 They are now passed through (except when using the C API function
2274 ``PyDict_GetItem()``, whose semantics did not change).
2275
2276- Bug #1456209: In some obscure cases it was possible for a class with a
2277 custom ``__eq__()`` method to confuse dict internals when class instances
2278 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
2279 No, you don't have any code that did this ;-)

Trent Mick960a3f82006-06-28 20:30:41 +00002284- Bug #1295808: expat symbols should be namespaced in pyexpat
2285
2286- Patch #1462338: Upgrade pyexpat to expat 2.0.0
2287
Brett Cannon6ee7d012006-06-08 16:23:04 +00002288- Change binascii.hexlify to accept a read-only buffer instead of only a char
2289 buffer and actually follow its documentation.
2290
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00002291- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
2292
Nick Coghlanc649ec52006-05-29 12:43:05 +00002293- Patch #1478788 (modified version): The functional extension module has
2294 been renamed to _functools and a functools Python wrapper module added.
2295 This provides a home for additional function related utilities that are

2299
Georg Brandl378d5922006-05-17 14:26:50 +00002300- Patch #1490224: time.altzone is now set correctly on Cygwin.
2301
Georg Brandl8d3342b2006-05-16 07:38:27 +00002302- Patch #1435422: zlib's compress and decompress objects now have a
2303 copy() method.
2304
Andrew MacIntyre92913322006-06-13 15:04:24 +00002305- Patch #1454481: thread stack size is now tunable at runtime for thread
2306 enabled builds on Windows and systems with Posix threads support.
2307
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002308- On Win32, os.listdir now supports arbitrarily-long Unicode path names
2309 (up to the system limit of 32K characters).
2310
2311- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
2312 As a result, these functions now raise WindowsError instead of OSError.
2313
Tim Peters7a822da2006-05-25 21:50:17 +00002314- ``time.clock()`` on Win64 should use the high-performance Windows
2315 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
2316 Windows platforms).
2317
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002318- Calling Tk_Init twice is refused if the first call failed as that
2319 may deadlock.
2320
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00002321- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
2322 accept it without potentially using an uninitialized pointer.
2323
2324- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
2325 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
2326 patch numbers 1494885 and 1494902]

2330
Gregory P. Smith372b5832006-06-05 18:48:21 +00002331- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
2332 parameter is supplied. [SF pybsddb bug #1477863]
2333
Gregory P. Smith3c228b12006-06-05 23:59:37 +00002334- bsddb: the __len__ method of a DB object has been fixed to return correct
2335 results. It could previously incorrectly return 0 in some cases.
2336 Fixes SF bug 1493322 (pybsddb bug 1184012).
2337
Gregory P. Smithff7d9912006-06-08 05:17:08 +00002338- bsddb: the bsddb.dbtables Modify method now raises the proper error and
2339 aborts the db transaction safely when a modifier callback fails.
2340 Fixes SF python patch/bug #1408584.
2341
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002342- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00002343 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002344 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
2345 database calls that would previously deadlock. [SF python bug #775414]

2370
Georg Brandl2605ca82006-06-14 06:08:31 +00002371- Bug #1339007: Shelf objects now don't raise an exception in their

2373
Martin v. Löwisd8251432006-06-14 05:21:04 +00002374- Patch #1455898: The MBCS codec now supports the incremental mode for
2375 double-byte encodings.
2376
Tim Peters43898b42006-06-14 04:09:25 +00002377- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2378 guarantee that adjacent triples in the return list always describe
2379 non-adjacent blocks. Previously, a pair of matching blocks could end
2380 up being described by multiple adjacent triples that formed a partition
2381 of the matching pair.

2389 clarify docs.
2390
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002391- The wsgiref package has been added to the standard library.
2392
Nick Coghlan676725d2006-06-08 13:54:49 +00002393- The functions update_wrapper() and wraps() have been added to the functools
2394 module. These make it easier to copy relevant metadata from the original
2395 function when writing wrapper functions.
2396
Tim Petersd6a9eef2006-06-05 01:48:21 +00002397- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2398 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002399
Martin v. Löwis3f767792006-06-04 19:36:28 +00002400- Patch #1359618: Speed up charmap encoder by using a trie structure
2401 for lookup.
2402
Tim Petersd609b1a2006-06-02 23:22:51 +00002403- The functions in the ``pprint`` module now sort dictionaries by key
2404 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2405 if and only if its display required more than one line, although that
2406 wasn't documented. The new behavior increases predictability; e.g.,
2407 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2408
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002409- Patch #1497027: try HTTP digest auth before basic auth in urllib2

2411
Georg Brandl2b330372006-05-28 20:23:12 +00002412- Patch #1496206: improve urllib2 handling of passwords with respect to
2413 default HTTP and HTTPS ports.
2414
George Yoshidaf3c65de2006-05-28 16:39:09 +00002415- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.

Bob Ippolito7298f272006-05-23 18:43:47 +00002417- Patch #1281707: speed up gzip.readline.
2418
Georg Brandlb89316f2006-05-17 15:51:16 +00002419- Patch #1180296: Two new functions were added to the locale module:
2420 format_string() to get the effect of "format % items" but locale-aware,
2421 and currency() to format a monetary number with currency sign.
2422
Georg Brandle3a25832006-05-17 14:56:04 +00002423- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2424 and several features added, such as speed and geometry control.
2425
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002426- Patch #1488881: add support for external file objects in bz2 compressed
2427 tarfiles.
2428
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002429- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2430 stdout arguments, making it possible to redirect input and output
2431 for remote debugging.
2432
2433- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2434 a couple of issues, notably handling of long file names using the
2435 GNU LONGNAME extension.
2436
2437- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2438 new flag when ``name`` is already the name of an option flag.
2439
2440- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2441 package.
2442
2443- Patch #1472854: make the rlcompleter.Completer class usable on non-
2444 UNIX platforms.

2485-----------------
2486
Thomas Heller1b046642006-04-18 18:51:06 +00002487- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2488 by converting these apis from macros into exported functions again:
2489
2490 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2491 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2492 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2493 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2494 PyRun_String Py_CompileString
2495
Martin v. Löwis45294a92006-04-18 06:24:08 +00002496- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2497
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002498- All uses of PyStructSequence_InitType have been changed to initialize
2499 the type objects only once, even if the interpreter is initialized
2500 multiple times.
2501
Neal Norwitz61546162006-04-14 05:20:28 +00002502- Bug #1454485, array.array('u') could crash the interpreter. This was
2503 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2504 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2505
2506- Py_UNICODE is unsigned. It was always documented as unsigned, but
2507 due to a bug had a signed value in previous versions.
2508
Tim Peters3a5e8b12006-04-11 01:44:07 +00002509- Patch #837242: ``id()`` of any Python object always gives a positive
2510 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2511 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002512 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002513 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002514
Tim Peters3a5e8b12006-04-11 01:44:07 +00002515 def __hash__(self):
2516 return id(self) # WRONG
2517
2518 because a hash result must be a (short) Python int but it was always
2519 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002520 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002521 was always usable as a hash value before this patch. That's no longer
2522 necessarily so.
2523
2524- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002525 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002526 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002527 #1454844)
2528
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002529- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2530 involving generators that have paused outside of any ``try`` or ``with``
2531 blocks. (In 2.5a1, a paused generator that was part of a reference
2532 cycle could not be garbage collected, regardless of whether it was
2533 paused in a ``try`` or ``with`` block.)

2547 the cachesize parameter.
2548
2549- Bug #1149413: bsddb.*open() no longer raises an exception when using
2550 a temporary db (file=None) with the 'n' flag to truncate on open.
2551
2552- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2553 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002554
Armin Rigoa9017c32006-04-19 11:50:27 +00002555- Patch #1062014: AF_UNIX sockets under Linux have a special

Peter Astrand7d1d4362006-07-14 14:04:45 +00002561- Bug #1223937: subprocess.CalledProcessError reports the exit status
2562 of the process using the returncode attribute, instead of
2563 abusing errno.
2564
Tim Peters711bf302006-04-25 03:31:36 +00002565- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2566 a doctest to be skipped (the code is not run, and the expected output
2567 or exception is ignored).
2568
Nick Coghlanda2268f2006-04-24 04:37:15 +00002569- Fixed contextlib.nested to cope with exceptions being raised and
2570 caught inside exit handlers.
2571
Greg Wardab05edc2006-04-23 03:47:58 +00002572- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2573 hex, octal, or binary; add ``append_const`` action; keep going if
2574 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2575 added ``epilog`` for better help generation).
2576
Tim Peters21fbd572006-04-21 21:18:10 +00002577- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2578 called from a thread spawned as a side effect of importing a module.
2579
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002580- The pydoc module now supports documenting packages contained in
2581 .zip or .egg files.
2582
2583- The pkgutil module now has several new utility functions, such
2584 as ``walk_packages()`` to support working with packages that are either
2585 in the filesystem or zip files.
2586
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002587- The mailbox module can now modify and delete messages from
2588 mailboxes, in addition to simply reading them. Thanks to Gregory
2589 K. Johnson for writing the code, and to the 2005 Google Summer of
2590 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002591
Tim Petersc7605f22006-04-17 21:12:33 +00002592- The ``__del__`` method of class ``local`` in module ``_threading_local``
2593 returned before accomplishing any of its intended cleanup.
2594
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002595- Patch #790710: Add breakpoint command lists in pdb.

2603
Phillip J. Eby47032112006-04-11 01:07:43 +00002604- The warnings, linecache, inspect, traceback, site, and doctest modules
2605 were updated to work correctly with modules imported from zipfiles or
2606 via other PEP 302 __loader__ objects.
2607
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002608- Patch #1467770: Reduce usage of subprocess._active to processes which
2609 the application hasn't waited on.

2614
Skip Montanaro262fb922006-04-21 02:31:07 +00002615- The pstats.Stats class accepts an optional stream keyword argument to
2616 direct output to an alternate file-like object.
2617
Anthony Baxter51bcb682006-04-05 14:51:42 +00002618Build
2619-----
2620
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002621- The Makefile now has a reindent target, which runs reindent.py on
2622 the library.
2623
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002624- Patch #1470875: Building Python with MS Free Compiler
2625
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002626- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002627
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002628- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2629 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002630 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002631 CXX from --with-cxx-main, see description in README.
2632
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002633- Patch #1429775: Link extension modules with the shared libpython.
2634
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002635- Fixed a libffi build problem on MIPS systems.
2636
Tim Peters8931ff12006-05-13 23:28:20 +00002637- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2638 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2639 and "%zu" for unsigned integers of type ``size_t``.
2640
Anthony Baxter51bcb682006-04-05 14:51:42 +00002641Tests
2642-----
2643
Nick Coghlanda2268f2006-04-24 04:37:15 +00002644- test_contextlib now checks contextlib.nested can cope with exceptions
2645 being raised and caught inside exit handlers.
2646
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002647- test_cmd_line now checks operation of the -m and -c command switches
2648
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002649- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2650 it separately and by hand. It also wasn't cleaning up its changes to
2651 the current Decimal context.
2652
Thomas Woutersabd08882006-04-26 15:53:30 +00002653- regrtest.py now has a -M option to run tests that test the new limits of
2654 containers, on 64-bit architectures. Running these tests is only sensible
2655 on 64-bit machines with more than two gigabytes of memory. The argument
2656 passed is the maximum amount of memory for the tests to use.
2657
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00002658Tools

Anthony Baxter51bcb682006-04-05 14:51:42 +00002664Documentation
2665-------------
2666
Tim Petersb06d28c2006-05-12 01:57:59 +00002667- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2668
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002669- PEP 343: Added Context Types section to the library reference
2670 and attempted to bring other PEP 343 related documentation into
2671 line with the implementation and/or python-dev discussions.
2672
Tim Peters8dc73d22006-04-24 02:03:16 +00002673- Bug #1337990: clarified that ``doctest`` does not support examples
2674 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002677What's New in Python 2.5 alpha 1?
2678=================================
2679
Anthony Baxterebed3f62006-04-03 15:03:44 +00002680*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002681
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002682Core and builtins
2683-----------------
2684
Nick Coghlan43832302006-04-23 17:04:07 +00002685- PEP 338: -m command line switch now delegates to runpy.run_module
2686 allowing it to support modules in packages and zipfiles
2687
Martin v. Löwisc661b882006-04-20 04:54:23 +00002688- On Windows, .DLL is not an accepted file name extension for
2689 extension modules anymore; extensions are only found if they
2690 end in .PYD.
2691
Martin v. Löwisea62d252006-04-03 10:56:49 +00002692- Bug #1421664: sys.stderr.encoding is now set to the same value as
2693 sys.stdout.encoding.
2694
Neal Norwitz92e212f2006-04-03 04:48:37 +00002695- __import__ accepts keyword arguments.
2696
Georg Brandlccadf842006-03-31 18:54:53 +00002697- Patch #1460496: round() now accepts keyword arguments.
2698
Anthony Baxter262c00a2006-03-30 10:53:17 +00002699- Fixed bug #1459029 - unicode reprs were double-escaped.
2700
Hye-Shik Changd478f342006-03-23 12:32:36 +00002701- Patch #1396919: The system scope threads are reenabled on FreeBSD
2702 5.4 and later versions.
2703
Neal Norwitze98ccf62006-03-23 05:39:47 +00002704- Bug #1115379: Compiling a Unicode string with an encoding declaration
2705 now gives a SyntaxError.
2706
Georg Brandlabd1ff82006-03-18 07:59:59 +00002707- Previously, Python code had no easy way to access the contents of a
2708 cell object. Now, a ``cell_contents`` attribute has been added
2709 (closes patch #1170323).
2710
Tim Peterscf79aac2006-03-16 01:14:46 +00002711- Patch #1123430: Python's small-object allocator now returns an arena to
2712 the system ``free()`` when all memory within an arena becomes unused
2713 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2714 freed. Some applications will see a drop in virtual memory size now,
2715 especially long-running applications that, from time to time, temporarily
2716 use a large number of small objects. Note that when Python returns an
2717 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002718 platform C library will in turn return that memory to the operating system.
2719 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002720 appears to be effective at least on Microsoft C and gcc-based systems.
2721 Thanks to Evan Jones for hard work and patience.
2722
Georg Brandl533ff6f2006-03-08 18:09:27 +00002723- Patch #1434038: property() now uses the getter's docstring if there is
2724 no "doc" argument given. This makes it possible to legitimately use
2725 property() as a decorator to produce a read-only property.
2726
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002727- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2728 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2729 of requiring an int or long in slicing and a few other contexts, enabling
2730 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2731
Neal Norwitz995acdf2006-03-07 05:01:00 +00002732- Fixed various bugs reported by Coverity's Prevent tool.
2733
Brett Cannonbf364092006-03-01 04:25:17 +00002734- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2735 new exception base class, BaseException, which has a new message attribute.
2736 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2737 Raising a string exception now raises a DeprecationWarning.
2738
Thomas Woutersfb609f42006-02-28 16:37:25 +00002739- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2740 explicitly relative, using 'from .module import name' to mean 'from the same
2741 package as this module is in. Imports without dots still default to the
2742 old relative-then-absolute, unless 'from __future__ import
2743 absolute_import' is used.
2744
Brett Cannona7446e32006-02-27 23:39:10 +00002745- Properly check if 'warnings' raises an exception (usually when a filter set
2746 to "error" is triggered) when raising a warning for raising string
2747 exceptions.
2748
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002749- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002750 The name was removed from Include/code.h.
2751
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002752- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002753
Guido van Rossum1968ad32006-02-25 22:38:04 +00002754- Patch 1433928:
2755 - The copy module now "copies" function objects (as atomic objects).
2756 - dict.__getitem__ now looks for a __missing__ hook before raising
2757 KeyError.
2758
Tim Peters84ef21c2006-02-28 20:39:06 +00002759- PEP 343: with statement implemented. Needs ``from __future__ import
2760 with_statement``. Use of 'with' as a variable will generate a warning.
2761 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002762 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002763 The following objects have __context__ methods:
2764 - The built-in file type.
2765 - The thread.LockType type.
2766 - The following types defined by the threading module:
2767 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2768 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002769
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002770- Fix the encodings package codec search function to only search
2771 inside its own package. Fixes problem reported in patch #1433198.
2772
2773 Note: Codec packages should implement and register their own
2774 codec search function. PEP 100 has the details.
2775
Tim Peters9ea89d22006-06-04 03:26:02 +00002776- PEP 353: Using ``Py_ssize_t`` as the index type.
2777
2778- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2779 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2780 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2781 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2782 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002783
Neal Norwitzfc76d632006-01-10 06:03:13 +00002784- Patch #1400181, fix unicode string formatting to not use the locale.
2785 This is how string objects work. u'%f' could use , instead of .
2786 for the decimal point. Now both strings and unicode always use periods.
2787
Neal Norwitz671b9e32006-01-09 07:07:12 +00002788- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2789 configure would break checking curses.h.
2790
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002791- Bug #959576: The pwd module is now builtin. This allows Python to be
2792 built on UNIX platforms without $HOME set.
2793
Neal Norwitzc10978f2005-12-19 06:07:16 +00002794- Bug #1072182, fix some potential problems if characters are signed.
2795
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002796- Bug #889500, fix line number on SyntaxWarning for global declarations.
2797
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002798- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2799
Neal Norwitze7214a12005-12-18 05:03:17 +00002800- Support for converting hex strings to floats no longer works.
2801 This was not portable. float('0x3') now raises a ValueError.
2802
Barry Warsaw2a38a862005-12-18 01:27:35 +00002803- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002804 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002805 is now displayed in interactive prompt banner.
2806
Georg Brandlfa166682005-12-17 21:45:17 +00002807- Implementation of PEP 341 - Unification of try/except and try/finally.
2808 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002809 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002810
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002811- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2812 now encodes backslash correctly.
2813
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002814- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2815
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002816- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002817 and long longs.
2818
Neal Norwitz67715f02005-11-09 06:59:35 +00002819- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002820 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002821 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002822
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002823- Replaced most Unicode charmap codecs with new ones using the
2824 new Unicode translate string feature in the builtin charmap
2825 codec; the codecs were created from the mapping tables available
2826 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2827 encodings now include a mapping for the Apple logo)
2828
Tim Peterse3547fd2005-12-16 23:13:57 +00002829- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002830
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002831- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002832
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002833- A new AST parser implementation was completed. The abstract
2834 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002835 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002836
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002837- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002838 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2839
Neal Norwitz708e51a2005-10-03 04:48:15 +00002840- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2841
Neal Norwitz11bd1192005-10-03 00:54:56 +00002842- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2843 Provide a warning when a directory is passed on the command line.
2844
Neal Norwitz40d37812005-10-02 01:48:49 +00002845- Fix segfault with invalid coding.
2846
2847- SF bug #772896: unknown encoding results in MemoryError.
2848
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002849- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002850 supported a __len__() method which evaluated to False when the iterator
2851 was empty.
2852
Guido van Rossum630db602005-09-20 18:49:54 +00002853- On 64-bit platforms, when __len__() returns a value that cannot be
2854 represented as a C int, raise OverflowError.
2855
Skip Montanarof8948ca2005-09-19 03:54:46 +00002856- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002857 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002858
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002859- SF bug #893549: parsing keyword arguments was broken with a few format
2860 codes.
2861
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002862- Changes donated by Elemental Security to make it work on AIX 5.3
2863 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2864 bug #105470: test_pwd fails on 64bit system (Opteron).
2865
Guido van Rossum539c6622005-09-14 17:49:54 +00002866- Changes donated by Elemental Security to make it work on HP-UX 11 on
2867 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2868
Georg Brandl4550b8d2005-08-26 06:43:52 +00002869- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002870 (fixes bug #1119418).
2871
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002872- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2873
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002874- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2875 exceptions that cause a function to exit.
2876
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002877- The implementation of set() and frozenset() was revised to use its
2878 own internal data structure. Memory consumption is reduced by 1/3
2879 and there are modest speed-ups as well. The API is unchanged.
2880
Tim Petersde7990b2005-07-17 23:45:23 +00002881- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2882
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002883- SF bug #1229429: PyObject_CallMethod failed to decrement some
2884 reference counts in some error exit cases.
2885
Tim Petersecc6e6a2005-07-10 22:30:55 +00002886- SF bug #1185883: Python's small-object memory allocator took over
2887 a block managed by the platform C library whenever a realloc specified
2888 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002889 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002890 portable way to copy data from the C-managed block into Python's
2891 small-object space without risking a memory fault. Python's small-object
2892 realloc now leaves such blocks under the control of the platform C
2893 realloc.
2894
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002895- SF bug #1232517: An overflow error was not detected properly when
2896 attempting to convert a large float to an int in os.utime().
2897
Raymond Hettinger3296e692005-06-29 23:29:56 +00002898- SF bug #1224347: hex longs now print with lowercase letters just
2899 like their int counterparts.
2900
Michael W. Hudson188d4362005-06-20 16:52:57 +00002901- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2902 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2903 interpreter states; back out that fix and do a better job (see
2904 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2905 for a longer write-up of the problem).
2906
Michael W. Hudsondf888462005-06-03 14:41:55 +00002907- SF patch #1180995: marshal now uses a binary format by default when
2908 serializing floats.
2909
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002910- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2911 the routines that promise to produce IEEE 754 binary representations
2912 of floats now simply copy bytes around.
2913
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002914- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2915 278.
2916
Brett Cannonc3647ac2005-04-26 03:45:26 +00002917- patch #1109424: int, long, float, complex, and unicode now check for the
2918 proper magic slot for type conversions when subclassed. Previously the
2919 magic slot was ignored during conversion. Semantics now match the way
2920 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002921 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002922 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002923 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002924
Barry Warsawc8d907c2005-04-19 23:43:40 +00002925- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2926 NULL, now raise an AttributeError when attempting to set or delete the
2927 attribute. Previously a TypeError was raised, but this was inconsistent
2928 with the equivalent pure-Python implementation.
2929
Michael W. Hudson774479c2005-04-18 08:46:17 +00002930- It is now safe to call PyGILState_Release() before
2931 PyEval_InitThreads() (note that if there is reason to believe there
2932 are multiple threads around you still must call PyEval_InitThreads()
2933 before using the Python API; this fix is for extension modules that
2934 have no way of knowing if Python is multi-threaded yet).
2935
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002936- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2937 disabled caused a crash.
2938
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002939- Bug #1165306: instancemethod_new allowed the creation of a method
2940 with im_class == im_self == NULL, which caused a crash when called.
2941
Tim Petersecc6e6a2005-07-10 22:30:55 +00002942- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002943 fixes the crash seen in bug #1165761
2944
Raymond Hettinger96229b12005-03-11 06:49:40 +00002945- Added two new builtins, any() and all().
2946
Brett Cannon409d8f22005-03-05 06:47:57 +00002947- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002948 (e.g., ``class C(): pass`` is no longer a syntax error).
2949 Patch #1176012 added support to the 'parser' module and 'compiler' package
2950 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002951
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002952- Patch #1115086: Support PY_LONGLONG in structmember.
2953
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002954- Bug #1155938: new style classes did not check that __init__() was
2955 returning None.
2956
Tim Petersecc6e6a2005-07-10 22:30:55 +00002957- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002958 ('\') with a specific error message.
2959
Martin v. Löwisff232d72005-03-03 09:24:38 +00002960- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2961
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002962- Bug #1124295: the __name__ attribute of file objects was
2963 inadvertently made inaccessible in restricted mode.
2964
Tim Petersecc6e6a2005-07-10 22:30:55 +00002965- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002966 an ferror() call.
2967
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002968- min() and max() now support key= arguments with the same meaning as in
2969 list.sort().
2970
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002971- The peephole optimizer now performs simple constant folding in expressions:
2972 (2+3) --> (5).
2973
Raymond Hettingera422c342005-01-11 03:03:27 +00002974- set and frozenset objects can now be marshalled. SF #1098985.
2975
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002976- Bug #1077106: Poor argument checking could cause memory corruption
2977 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002978
Jeremy Hyltonab630502005-02-04 18:44:06 +00002979- The parser did not complain about future statements in illegal
2980 positions. It once again reports a syntax error if a future
2981 statement occurs after anything other than a doc string.
2982
Neil Schemenauercf52c072005-08-12 17:34:58 +00002983- Change the %s format specifier for str objects so that it returns a
2984 unicode instance if the argument is not an instance of basestring and
2985 calling __str__ on the argument returns a unicode instance.
2986
Tim Petersf4e69282006-02-27 17:15:31 +00002987- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2988 current thread state when the auto-GIL-state machinery knows about
2989 it (since the thread state is being deleted, continuing to remember it
2990 can't help, but can hurt if another thread happens to get created with
2991 the same thread id).
2992

3010
3011- The following modules were removed: regsub, reconvert, regex, regex_syntax.
3012
3013- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00003014 is deprecated. The undocumented re.engine variable no longer exists.

3018
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00003019- The unicodedata module was updated to the 4.1 version of the Unicode
3020 database. The 3.2 version is still available as unicodedata.db_3_2_0
3021 for applications that require this specific version (such as IDNA).
3022
Neal Norwitzb62c4332006-03-04 18:35:47 +00003023- The timing module is no longer built by default. It was deprecated
3024 in PEP 4 in Python 2.0 or earlier.
3025
Guido van Rossum1968ad32006-02-25 22:38:04 +00003026- Patch 1433928: Added a new type, defaultdict, to the collections module.

3044
Martin v. Löwis14694662006-02-03 12:54:16 +00003045- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
3046 are reported, the limit on path name lengths is removed, and stat reports
3047 WindowsError now (instead of OSError).
3048
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00003049- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

3124 the request code argument, which results in more C-like behaviour
3125 for large or negative values.
3126
Tim Petersecc6e6a2005-07-10 22:30:55 +00003127- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

3166
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003167- the cPickle module no longer accepts the deprecated None option in the
3168 args tuple returned by __reduce__().
3169
Raymond Hettingerb2594052004-12-05 09:25:51 +00003170- itertools.islice() now accepts None for the start and step arguments.
3171 This allows islice() to work more readily with slices:
3172 islice(s.start, s.stop, s.step)
3173
Skip Montanaro0af3ade2005-01-13 04:12:31 +00003174- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00003183- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
3184 been renamed to have only a single underscore prefix. This was done to
3185 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003186
Nick Coghlan43832302006-04-23 17:04:07 +00003187- PEP 338: new module runpy defines a run_module function to support
3188 executing modules which provide access to source code or a code object
3189 via the PEP 302 import mechanisms.
3190
Anthony Baxter93f5b932006-04-03 08:05:07 +00003191- The email module's parsedate_tz function now sets the daylight savings
3192 flag to -1 (unknown) since it can't tell from the date whether it should

3199 in attribute values.
3200
Anthony Baxterc51ee692006-04-01 00:57:31 +00003201- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00003202 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00003203 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00003204 module will not be built.
3205
Tim Petersc17976e2006-04-01 00:26:53 +00003206- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
3207 aren't officially supported here, and trying to use them will probably
3208 raise an exception some day. But dicts have been allowed, and "mostly
3209 worked", so support for them won't go away without warning.
3210
Georg Brandl338ef7d2006-03-31 18:42:16 +00003211- Bug #1445068: getpass.getpass() can now be given an explicit stream
3212 argument to specify where to write the prompt.
3213
Georg Brandl22ec80b2006-03-31 18:25:44 +00003214- Patch #1462313, bug #1443328: the pickle modules now can handle classes
3215 that have __private names in their __slots__.

3221
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00003222- Queue.Queue objects now support .task_done() and .join() methods
3223 to make it easier to monitor when daemon threads have completed
3224 processing all enqueued tasks. Patch #1455676.
3225
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00003226- popen2.Popen objects now preserve the command in a .cmd attribute.

3229
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00003230- email 4.0 package now integrated. This is largely the same as the email 3.0
3231 package that was included in Python 2.3, except that PEP 8 module names are
3232 now used (e.g. mail.message instead of email.Message). The MIME classes
3233 have been moved to a subpackage (e.g. email.mime.text instead of
3234 email.MIMEText). The old names are still supported for now. Several
3235 deprecated Message methods have been removed and lots of bugs have been
3236 fixed. More details can be found in the email package documentation.
3237
Walter Dörwald40108c92006-03-27 08:15:44 +00003238- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
3239 (a subclass of tuple) that provides incremental decoders and encoders
3240 (a way to use stateful codecs without the stream API). Python functions
3241 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
3242 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
3243 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00003244
Walter Dörwald067db482006-03-15 22:17:27 +00003245- Patch #1359365: Calling next() on a closed StringIO.String object raises
3246 a ValueError instead of a StopIteration now (like file and cString.String do).
3247 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
3248 called before (like file and StringIO.StringIO do).

3262 and helpful context managers nested() and closing().
3263

Martin v. Löwis3e865952006-01-24 15:51:21 +00003298 specifications, raises IOErrors when proxies for unsupported protocols
3299 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00003322 SHA1, 224, 256, 384, and 512. Note that recent developments make the
3323 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
3324 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
3325 Ronald L. Rivest offered this advice for Python:
3326
3327 "The consensus of researchers in this area (at least as
3328 expressed at the NIST Hash Function Workshop 10/31/05),
3329 is that SHA-256 is a good choice for the time being, but
3330 that research should continue, and other alternatives may
3331 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00003332
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00003333- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandla4a8b822005-07-15 09:13:21 +00003403- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
3404 parameter, but uses the usual "kwargs=None".
3405
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003406- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00003407 Patch #1209527 (Contributed by Connelly).
3408
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00003409- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
3410 to W3C name (404 -> 'Not Found'). RFE #1216944.
3411
Georg Brandl9e43acf2005-07-04 17:16:07 +00003412- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
3413 as this can cause problems with apps closing all file descriptors.
3414
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00003415- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003416 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00003417
Georg Brandl2f210b62005-06-26 22:09:06 +00003418- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
3419
Georg Brandlfbff1bc2005-06-26 21:36:25 +00003420- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
3421 error messages.
3422
Georg Brandl379f99d2005-06-26 21:09:38 +00003423- Bug #1108948: Cookie.py produced invalid JavaScript code.
3424
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00003425- The tokenize module now detects and reports indentation errors.
3426 Bug #1224621.
3427
Raymond Hettinger68c04532005-06-10 11:05:19 +00003428- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00003429 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00003430 the generate_tokens() function now accepts a callable argument that
3431 terminates by raising StopIteration.
3432
Georg Brandl9166e1a2005-06-04 09:20:03 +00003433- Bug #1196315: fix weakref.WeakValueDictionary constructor.
3434
Georg Brandl268e61c2005-06-03 14:28:50 +00003435- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
3436 component of the path.
3437
Skip Montanaro174dd222005-05-14 20:54:16 +00003438- Patch #1120353: The xmlrpclib module provides better, more transparent,
3439 support for datetime.{datetime,date,time} objects. With use_datetime set
3440 to True, applications shouldn't have to fiddle with the DateTime wrapper
3441 class at all.
3442
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00003443- distutils.commands.upload was added to support uploading distribution
3444 files to PyPI.
3445
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00003446- distutils.commands.register now encodes the data as UTF-8 before posting
3447 them to PyPI.
3448
Raymond Hettinger267b8682005-03-27 10:47:39 +00003449- decimal operator and comparison methods now return NotImplemented
3450 instead of raising a TypeError when interacting with other types. This
3451 allows other classes to implement __radd__ style methods and have them
3452 work as expected.
3453
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003454- Bug #1163325: Decimal infinities failed to hash. Attempting to
3455 hash a NaN raised an InvalidOperation instead of a TypeError.
3456
Tim Petersecc6e6a2005-07-10 22:30:55 +00003457- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00003458 stream compression; add, for symmetry reasons, r:* as a synonym of r.
3459
Martin v. Löwis00a73e72005-03-04 19:40:34 +00003460- Patch #1043890: Add extractall method to tarfile.

3489
Raymond Hettingerbab41432005-02-05 01:31:19 +00003490- Fixed bug in a NameError bug in cookielib. Patch #1116583.
3491
Guido van Rossumd0641422005-02-03 15:01:24 +00003492- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3493 disables recursive traversal through instance attributes, which can
3494 be exploited in various ways.
3495
Tim Peterse3547fd2005-12-16 23:13:57 +00003496- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003497 flags on the HTTP listening socket.
3498
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003499- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3500 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3501
Fred Drakefbdeaad2006-07-29 16:56:15 +00003502- Patches #893642, #1039083: add allow_none, encoding arguments to
3503 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003504
Martin v. Löwis1d11de62005-01-29 13:29:23 +00003505- Bug #1110478: Revert os.environ.update to do putenv again.
3506
Thomas Hellerd6c6e222005-01-20 19:20:16 +00003507- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3508
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003509- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3510
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003511- Enhancements to the csv module:
3512
3513 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003514 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003515 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003516 + Dialect parameter parsing has been re-implemented to improve error
3517 reporting.
3518 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3519 dictates.
3520 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003521 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003522 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003523 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3524 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003525 + reader now allows \r characters to be quoted (previously it only allowed
3526 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003527 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003528 + Dialect classes passed to the module are no longer instantiated by
3529 the module before being parsed (the former validation scheme required
3530 this, but the mechanism was unreliable).
3531 + The dialect registry now contains instances of the internal
3532 C-coded dialect type, rather than references to python objects.
3533 + the internal c-coded dialect type is now immutable.
3534 + register_dialect now accepts the same keyword dialect specifications
3535 as the reader and writer, allowing the user to register dialects
3536 without first creating a dialect class.
3537 + a configurable limit to the size of parsed fields has been added -
3538 previously, an unmatched quote character could result in the entire
3539 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003540 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003541 the parser field size limit (returning the former limit). The initial
3542 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003543 + A line_num attribute has been added to the reader object, which tracks
3544 the number of lines read from the source iterator. This is not
3545 the same as the number of records returned, as records can span
3546 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003547 + reader and writer objects were not being registered with the cyclic-GC.
3548 This has been fixed.
3549
Brett Cannone6539c42005-01-08 02:43:53 +00003550- _DummyThread objects in the threading module now delete self.__block that is
3551 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3552 lock primitives tend to be limited in number and thus should not be wasted on
3553 a _DummyThread object. Fixes bug #1089632.
3554
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003555- The imghdr module now detects Exif files.
3556
Raymond Hettinger6065d322004-12-20 23:51:53 +00003557- StringIO.truncate() now correctly adjusts the size attribute.
3558 (Bug #951915).
3559
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003560- locale.py now uses an updated locale alias table (built using
3561 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3562 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003563 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003564
Raymond Hettinger3557f422004-12-07 12:02:02 +00003565- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3566
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003567- the pickle module no longer accepts the deprecated None option in the
3568 args tuple returned by __reduce__().
3569
Brett Cannon84667c02004-12-07 03:25:18 +00003570- optparse now optionally imports gettext. This allows its use in setup.py.
3571
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003572- the pickle module no longer uses the deprecated bin parameter.
3573
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003574- the shelve module no longer uses the deprecated binary parameter.
3575
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003576- the pstats module no longer uses the deprecated ignore() method.
3577
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003578- the filecmp module no longer uses the deprecated use_statcache argument.
3579
Raymond Hettinger664347b2004-12-04 21:21:53 +00003580- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3581 extended or overridden by subclasses. Formerly, the subclassed method would
3582 be ignored by the rest of the module. (Bug #1078905).
3583
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003584- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003585 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003586
Walter Dörwald36733692004-12-22 12:50:50 +00003587- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3588 once when a size argument is given. This prevents a buffer overflow in the
3589 tokenizer with very long source lines.
3590
Barry Warsaw538561e2006-01-01 21:48:54 +00003591- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3592 immediately after creating the object, without any intervening
3593 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003594
Skip Montanaro05885812005-01-16 20:48:27 +00003595- The reconvert.quote function can now emit triple-quoted strings. The
3596 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003597
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003598- ``UserString.MutableString`` now supports negative indices in
3599 ``__setitem__`` and ``__delitem__``
3600
Greg Ward40407942005-03-05 02:53:17 +00003601- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3602 correctly.
3603
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003604- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3605 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3606 character even if the user has passed a size parameter to get a proper
3607 line ending. Remove the special handling of a "\r\n" that has been split
3608 between two lines.
3609
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003610- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3611 about illegal code points. The codec now supports PEP 293 style error
3612 handlers.
3613
Walter Dörwald78a78b02005-09-01 12:04:29 +00003614- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003615 from the input stream, so that the output is a byte string in the correct
3616 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003617
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003618- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3619 considering it exactly like a '*'.
3620
Walter Dörwald007f8df2005-10-09 19:42:27 +00003621- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3622 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003623
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003624- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3625
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003626- Patch #1413711: Certain patterns of differences were making difflib
3627 touch the recursion limit.
3628
Walter Dörwald58917a62006-03-31 15:26:22 +00003629- Bug #947906: An object oriented interface has been added to the calendar
3630 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003631 called as a script (e.g. via ``python -mcalendar``). Localized month and
3632 weekday names can be ouput (even if an exotic encoding is used) using
3633 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003634

3653
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003654- Bug #1189330: configure did not correctly determine the necessary
3655 value of LINKCC if python was built with GCC 4.0.
3656
Trent Mick8321b422005-07-26 02:29:21 +00003657- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3658 vulnerability in zlib 1.2.1 and 1.2.2.
3659
Brett Cannon08cd5982005-04-24 22:26:38 +00003660- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3661 flags that change binary compatibility. Changes were also made to
3662 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003663 compilation of the interpreter and of C extensions through distutils.

Bob Ippolitoed233462005-03-29 13:47:59 +00003665- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3666 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3667 no longer exists). This configure patch makes things right.
3668
Martin v. Löwise2713be2005-03-08 15:03:08 +00003669- Bug #1158607: Build with --disable-unicode again.
3670
Brett Cannon46d96232005-02-16 00:07:19 +00003671- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3672 defined. Discovered as a result of not being able to build on OS X.
3673
Brett Cannon516592f2004-12-07 00:42:59 +00003674- setup.py now uses the directories specified in LDFLAGS using the -L option
3675 and in CPPFLAGS using the -I option for adding library and include
3676 directories, respectively, for compiling extension modules against. This has
3677 led to the core being compiled using the values in CPPFLAGS. It also removes
3678 the need for the special-casing of both DarwinPorts and Fink for darwin since
3679 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3680 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3681 Fink, ``-I/opt/local/include`` for DarwinPorts).
3682
Brett Cannon43802422005-02-10 20:48:03 +00003683- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3684 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3685 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3686 Closes bug #1096244. Thanks Gregory Bond.

3689-----
3690
Tim Petersc9d78aa2006-03-26 23:27:58 +00003691- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3692 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3693 is obtained via the ``PyObject_`` family, it must be released via the
3694 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3695 always been officially true, but when Python's small-object allocator was
3696 introduced, an attempt was made to cater to a few extension modules
3697 discovered at the time that obtained memory via ``PyObject_New`` but
3698 released it via ``PyMem_DEL``. It's years later, and if such code still
3699 exists it will fail now (probably with segfaults, but calling wrong
3700 low-level memory management functions can yield many symptoms).
3701
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003702- Added a C API for set and frozenset objects.
3703

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003706- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3707 mapping argument now. This string is used as a mapping table. Byte values
3708 greater than the length of the string and 0xFFFE are treated as undefined
3709 mappings.

Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003717- Patch #1276356: New resource "urlfetch" is implemented. This enables
3718 even impatient people to run tests that require remote files.
