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
Christian Heimes9c201962008-01-14 03:33:52 +000015- Object/structseq.c: Implemented new structseq representation. structseqs
16 like the return value of os.stat are more readable.
17
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +000018- Patch #1700288: added a type attribute cache that caches method accesses,
19 resulting in speedups in heavily object-oriented code.
20
Neal Norwitz3fc15b82008-01-10 05:42:58 +000021- Bug #1776: __import__() no longer accepts filenames on any platform.
22 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +000023
Georg Brandlaed6c662008-01-07 17:25:53 +000024- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
25
Georg Brandl2da0fce2008-01-07 17:09:35 +000026- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE envvar
27 and sys.dont_write_bytecode attribute. All these can be set to forbid Python
28 to attempt to write compiled bytecode files.
29
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +000030- Improve some exception messages when Windows fails to load an extension
31 module. Now we get for example '%1 is not a valid Win32 application' instead
32 of 'error code 193'.
33
Christian Heimes8267d1d2008-01-04 00:37:34 +000034- Bug #1481296: Fixed long(float('nan'))!=0L.
35
Christian Heimeseebb79c2008-01-03 22:32:26 +000036- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x, y)
37 functions.
Christian Heimese2ca4242008-01-03 20:23:15 +000038
Christian Heimes0a8143f2007-12-18 23:22:54 +000039- Issue #1635: Platform independent creation and representation of NaN
40 and INF. float("nan"), float("inf") and float("-inf") now work on every
41 platform with IEEE 754 semantics.
42
Raymond Hettingerfd7ed402007-12-18 21:24:09 +000043- Compiler now generates simpler and faster code for dictionary literals.
44 The oparg for BUILD_MAP now indicates an estimated dictionary size.
45 There is a new opcode, STORE_MAP, for adding entries to the dictionary.
46
Christian Heimesdb3d6cb2007-12-16 21:39:43 +000047- Issue #1638: %zd configure test fails on Linux
48
Christian Heimes90e10e72007-12-14 02:35:23 +000049- Issue #1620: New property decorator syntax was modifying the decorator
50 in place instead of creating a new decorator object.
51
Christian Heimes284d9272007-12-10 22:28:56 +000052- Issue #1580: New free format floating point representation based on
53 "Floating-Point Printer Sample Code", by Robert G. Burger. For example
54 repr(11./5) now returns '2.2' instead of '2.2000000000000002'.
55
Skip Montanaro26015492007-12-08 15:33:24 +000056- Issue #1538: Avoid copying string in split/rsplit if the split
57 char is not found.
58
Andrew M. Kuchling395fe442007-12-05 13:27:20 +000059- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +000060 SystemError.
61
Nick Coghlanef01d822007-12-03 12:55:17 +000062- PEP 366: Allow explicit relative imports when executing modules
63 inside packages with the -m switch via a new module level
64 __package__ attribute.
65
Christian Heimesdfdfaab2007-12-01 11:20:10 +000066- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
67 ``PyFloat_GetInfo()`` to the float API.
68
Amaury Forgeot d'Arcdafd32b2007-11-30 20:51:40 +000069- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
70 format code incorrectly truncated the length to an int, even when
71 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
72 results with huge strings.
73
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +000074- Issue #1402: Fix a crash on exit, when another thread is still running, and
75 if the deallocation of its frames somehow calls the PyGILState_Ensure() /
76 PyGILState_Release() functions.
77
Christian Heimes28104c52007-11-27 23:16:44 +000078- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
79
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +000080- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
81 attribute of an empty cell object.
82
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +000083- Issue #1460: The utf-7 incremental decoder did not accept truncated input.
84 It now correctly saves its state between chunks of data.
85
Nick Coghlan327a39b2007-11-18 11:56:28 +000086- Patch #1739468: Directories and zipfiles containing a __main__.py file can
87 now be directly executed by passing their name to the interpreter. The
88 directory/zipfile is automatically inserted as the first entry in sys.path.
89
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +000090- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
91 generator expression when at the same time the executed code is closing a
92 paused generator.
93
Raymond Hettinger1760c8a2007-11-08 02:52:43 +000094- sets and frozensets now have an isdisjoint() method.
95
Raymond Hettinger3f8caa32007-10-24 01:28:33 +000096- optimize the performance of builtin.sum().
97
Neal Norwitz44f326e2007-10-05 05:29:17 +000098- Fix warnings found by the new version of the Coverity checker.
99
Raymond Hettinger8f669372007-10-03 21:18:11 +0000100- The enumerate() builtin function is no longer bounded to sequences smaller
101 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
102 shifts from ints to longs.
103
Brett Cannon0b14f242007-09-30 19:45:10 +0000104- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
105 having a self-referential tuple, which is possible from C code. Nor did
106 object's tp_str consider that a type's tp_str could do something that could
107 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
108 respectively, fixed the issues.
109
Brett Cannon01531592007-09-17 03:28:34 +0000110- Issue #1164: It was possible to trigger deadlock when using the 'print'
111 statement to write to a file since the GIL was not released as needed. Now
112 PyObject_Print() does the right thing along with various tp_print
113 implementations of the built-in types and those in the collections module.
114
Brett Cannon4c20bc42007-09-11 21:02:28 +0000115- Issue #1147: Exceptions were directly allowing string exceptions in their
116 throw() method even though string exceptions no longer allowed.
117
Brett Cannona0c05512007-09-10 21:38:27 +0000118- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
119 list by using the recursion counter.
120
Brett Cannon1e534b52007-09-07 04:18:30 +0000121- Issue #1202533: Fix infinite recursion calls triggered by calls to
122 PyObject_Call() never calling back out to Python code to trigger recursion
123 depth updates/checks. Required the creation of a static RuntimeError
124 instance in case normalizing an exception put the recursion check value past
125 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
126
Martin v. Löwisa5136192007-09-04 14:19:28 +0000127- Patch #1031213: Decode source line in SyntaxErrors back to its original source
128 encoding.
129
Neal Norwitz766d8802007-08-03 06:46:29 +0000130- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
131
Martin v. Löwis68192102007-07-21 06:55:02 +0000132- PEP 3123: Provide forward compatibility with Python 3.0, while keeping
133 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
134 PyVarObject_HEAD_INIT.
135
Georg Brandl7c3b50d2007-07-12 08:38:00 +0000136- Patch #1673759: add a missing overflow check when formatting floats
137 with %G.
138
Martin v. Löwis6371cd82007-06-09 07:42:52 +0000139- Patch #1733960: Allow T_LONGLONG to accept ints.
140
Walter Dörwald84a3efe2007-06-13 16:57:12 +0000141- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
142
Neal Norwitzdb2b1b32007-06-11 07:36:24 +0000143- Prevent expandtabs() on string and unicode objects from causing a segfault
144 when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +0000145
Martin v. Löwisda587ab2007-06-08 17:29:20 +0000146- Bug #1733488: Fix compilation of bufferobject.c on AIX.
147
Georg Brandl25497a12007-06-01 19:20:27 +0000148- Bug #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +0000149
Neal Norwitz0ac60192007-05-27 04:08:54 +0000150- Add new attribute names for function objects. All the func_* become
151 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
152
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +0000153- Add -3 option to the interpreter to warn about features that are
154 deprecated and will be changed/removed in Python 3.0.
155
Georg Brandl2134e752007-05-21 20:34:16 +0000156- Patch #1686487: you can now pass any mapping after '**' in function
157 calls.
158
Collin Winter62903052007-05-18 23:11:24 +0000159- except clauses may now be spelled either "except E, target:" or
160 "except E as target:". This is to provide forwards compatibility with
161 Python 3.0.
162
Brett Cannon229cee22007-05-05 01:34:02 +0000163- Deprecate BaseException.message as per PEP 352.
164
Armin Rigo9790a272007-05-02 19:23:31 +0000165- Bug #1303614: don't expose object's __dict__ when the dict is
166 inherited from a builtin base.
167
Vinay Sajip8549ce32007-05-06 17:53:37 +0000168- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +0000169 setting a plain string, ie don't expand to single letter identifiers.
170
Raymond Hettinger13936692007-04-11 18:40:58 +0000171- Request #1191699: Slices can now be pickled.
172
Raymond Hettinger4db5fe92007-04-12 04:10:00 +0000173- Request #1193128: str.translate() now allows a None argument for
174 translations that only remove characters without re-mapping the
175 remaining characters.
176
Georg Brandl5cb76c12007-03-21 09:00:39 +0000177- Patch #1682205: a TypeError while unpacking an iterable is no longer
178 masked by a generic one with the message "unpack non-sequence".
179
Neal Norwitzaa754b72007-03-21 06:39:48 +0000180- Remove unused file Python/fmod.c.
181
Guido van Rossum143b5642007-03-23 04:58:42 +0000182- Bug #1683368: The object.__init__() and object.__new__() methods are
183 now stricter in rejecting excess arguments. The only time when
184 either allows excess arguments is when it is not overridden and the
185 other one is. For backwards compatibility, when both are
186 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +0000187 warning later). Also, type.__init__() insists on the same signature
188 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +0000189
Georg Brandl2b869942007-03-17 16:08:45 +0000190- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
191 to complex using its __complex__() method before falling back to the
192 __float__() method. Therefore, the functions in the cmath module now
193 can operate on objects that define a __complex__() method.
194
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +0000195- Patch #1623563: allow __class__ assignment for classes with __slots__.
196 The old and the new class are still required to have the same slot names.
197
Collin Winter77c67bd2007-03-16 04:11:30 +0000198- Patch #1642547: Fix an error/crash when encountering syntax errors in
199 complex if statements.
200
Žiga Seilnacht20f43d32007-03-15 11:44:55 +0000201- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
202 is called with an object that is faking its type.
203
Žiga Seilnacht71436f02007-03-14 12:24:09 +0000204- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
205 name.
206
Georg Brandl5240d742007-03-13 20:46:32 +0000207- Patch #1444529: the builtin compile() now accepts keyword arguments.
208
Georg Brandl7b9c5552007-03-12 14:30:05 +0000209- Bug #1678647: write a newline after printing an exception in any
210 case, even when converting the value to a string failed.
211
Georg Brandl871f1bc2007-03-12 13:17:36 +0000212- The dir() function has been extended to call the __dir__() method on
213 its argument, if it exists. If not, it will work like before. This allows
214 customizing the output of dir() in the presence of a __getattr__().
215
Collin Winter276887b2007-03-12 16:11:39 +0000216- Patch #922167: Python no longer segfaults when faced with infinitely
217 self-recursive reload() calls (as reported by bug #742342).
218
Žiga Seilnacht89032082007-03-11 15:54:54 +0000219- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
220
Collin Wintere38051d2007-03-09 20:33:07 +0000221- Patch #1491866: change the complex() constructor to allow parthensized
222 forms. This means complex(repr(x)) now works instead of raising a
223 ValueError.
224
Georg Brandlaa2321b2007-03-07 00:40:28 +0000225- Patch #703779: unset __file__ in __main__ after running a file. This
226 makes the filenames the warning module prints much more sensible when
227 a PYTHONSTARTUP file is used.
228
Georg Brandl49aafc92007-03-07 00:34:46 +0000229- Variant of patch #697613: don't exit the interpreter on a SystemExit
230 exception if the -i command line option or PYTHONINSPECT environment
231 variable is given, but break into the interactive interpreter just like
232 on other exceptions or normal program exit.
233
Georg Brandl00cd8182007-03-06 18:41:12 +0000234- Patch #1638879: don't accept strings with embedded NUL bytes in long().
235
Georg Brandl098cd692007-03-06 12:17:50 +0000236- Bug #1674503: close the file opened by execfile() in an error condition.
237
Georg Brandl0fca97a2007-03-05 22:28:08 +0000238- Patch #1674228: when assigning a slice (old-style), check for the
239 sq_ass_slice instead of the sq_slice slot.
240
Neal Norwitz88516a62007-02-26 22:41:45 +0000241- When printing an unraisable error, don't print exceptions. before the name.
242 This duplicates the behavior whening normally printing exceptions.
243
Martin v. Löwisfd963262007-02-09 12:19:32 +0000244- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
245
Brett Cannon129bd522007-01-30 21:34:36 +0000246- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
247 catch a string exception raises DeprecationWarning.
248
Brett Cannonf5bee302007-01-23 23:21:22 +0000249- Bug #1377858: Fix the segfaulting of the interpreter when an object created
250 a weakref on itself during a __del__ call for new-style classes (classic
251 classes still have the bug).
252
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000253- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
254 frame's thread state.
255
Thomas Wouters6ed19652007-01-23 13:50:49 +0000256- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
257
Martin v. Löwis4885e7d2007-01-19 06:42:22 +0000258- Bug #1637022: Prefix AST symbols with _Py_.
259
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000260- Prevent seg fault on shutdown which could occur if an object
261 raised a warning.
262
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000263- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
264 to avoid relying on atexit.
265
Raymond Hettinger94547f72006-12-20 06:42:06 +0000266- Bug #1590891: random.randrange don't return correct value for big number
267
Georg Brandl283a1352006-11-19 08:48:30 +0000268- Patch #1586791: Better exception messages for some operations on strings,
269 tuples and lists.
270

Neal Norwitz85dbec62006-11-04 19:25:22 +0000275- Bug #1588287: fix invalid assertion for `1,2` in debug builds.
276
Georg Brandlb9f4ad32006-10-29 18:31:42 +0000277- Bug #1576657: when setting a KeyError for a tuple key, make sure that
278 the tuple isn't used as the "exception arguments tuple".
279
Neal Norwitz21997af2006-10-28 21:19:07 +0000280- Bug #1565514, SystemError not raised on too many nested blocks.
281
Thomas Hellerdf08f0b2006-10-27 18:31:36 +0000282- Bug #1576174: WindowsError now displays the windows error code
283 again, no longer the posix error code.
284
Martin v. Löwisb5bc5372006-10-27 06:16:31 +0000285- Patch #1549049: Support long values in structmember, issue warnings
286 if the assigned value for structmember fields gets truncated.
287
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000288- Update the peephole optimizer to remove more dead code (jumps after returns)
289 and inline unconditional jumps to returns.
290
Georg Brandl2c1375c2006-10-12 11:27:59 +0000291- Bug #1545497: when given an explicit base, int() did ignore NULs

1012 time so that opening a database previously created with the DB_DUP or
1013 DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
1014 Specifically: dictionary assignment to a DB object will replace all
1015 values for a given key when the database allows duplicate values.
1016 DB users should use DB.put(k, v) when they want to store duplicates; not
1017 DB[k] = v.
1018
Gregory P. Smithac11e022007-11-05 02:56:31 +00001019- Add the bsddb.db.DBEnv.lock_id_free method.

1341-----------------
1342
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001343- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001344 compared equal or unequal to a string and a UnicodeDecodeError
1345 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001346
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001347 Instead, the equal (==) and unequal (!=) comparison operators will
1348 now issue a UnicodeWarning and interpret the two objects as
1349 unequal. The UnicodeWarning can be filtered as desired using
1350 the warning framework, e.g. silenced completely, turned into an
1351 exception, logged, etc.
1352
1353 Note that compare operators other than equal and unequal will still
1354 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001355
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001356- Fix segfault when doing string formatting on subclasses of long.

1360
1361- Fix bug related to __len__ functions returning negative values with
1362 classic classes.
1363
1364- Patch #1538606, Fix __index__() clipping. There were some problems
1365 discovered with the API and how integers that didn't fit into Py_ssize_t
1366 were handled. This patch attempts to provide enough alternatives
1367 to effectively use __index__.
1368
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001369- Bug #1536021: __hash__ may now return long int; the final hash
1370 value is obtained by invoking hash on the long int.
1371
Thomas Hellerab1049c2006-08-08 17:37:00 +00001372- Bug #1536786: buffer comparison could emit a RuntimeWarning.

1375 sys.stdin is closed.
1376
Thomas Heller74d36f02006-08-04 18:17:40 +00001377- On Windows, the PyErr_Warn function is now exported from
1378 the Python dll again.
1379
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001380- Bug #1191458: tracing over for loops now produces a line event
1381 on each iteration. Fixing this problem required changing the .pyc
1382 magic number. This means that .pyc files generated before 2.5c1
1383 will be regenerated.
1384
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001385- Bug #1333982: string/number constants were inappropriately stored
1386 in the byte code and co_consts even if they were not used, ie
1387 immediately popped off the stack.
1388
Georg Brandle9462c72006-08-04 18:03:37 +00001389- Fixed a reference-counting problem in property().

1393-------
1394
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001395- Fix a bug in the ``compiler`` package that caused invalid code to be
1396 generated for generator expressions.
1397
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001398- The distutils version has been changed to 2.5.0. The change to
1399 keep it programmatically in sync with the Python version running
1400 the code (introduced in 2.5b3) has been reverted. It will continue
1401 to be maintained manually as static string literal.
1402
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001403- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001404 and this cannot be converted to the required C type, an exception is
1405 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001406 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001407
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001408- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001409 an exception.
1410
Tim Petersc10c9d02006-09-05 02:18:09 +00001411- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001412 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001413 workarounds for clocks with low resolution, to stop the code yielding
1414 duplicate UUIDs.
1415
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001416- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1417 before raising SystemExit, allowing IDLE to honor quit() and exit().
1418
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001419- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

1445 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1446
Thomas Heller86720042006-08-14 11:17:48 +00001447- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1448 uses the _as_parameter_ attribute when objects are passed to foreign
1449 function calls. The ctypes version number was changed to 1.0.1.
1450
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001451- Bug #1530559, struct.pack raises TypeError where it used to convert.
1452 Passing float arguments to struct.pack when integers are expected
1453 now triggers a DeprecationWarning.

Fred Drake53912162006-07-29 13:22:49 +00001498What's New in Python 2.5 beta 3?
1499================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001500
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001501*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001502
1503Core and builtins
1504-----------------
1505
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001506- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001507 returned a long (see PEP 353).
1508
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001509- Bug #1515471: string.replace() accepts character buffers again.
1510
Neal Norwitz07aadb12006-07-30 06:55:48 +00001511- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1512 This provides the proper warning for struct.pack().
1513 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1514
Neal Norwitz0d62a062006-07-30 06:53:31 +00001515- Patch #1531113: Fix augmented assignment with yield expressions.
1516 Also fix a SystemError when trying to assign to yield expressions.
1517
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001518- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1519 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1520 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1521 excessive filesystem operations during imports.
1522
Tim Petersbc24eee2006-07-27 01:14:53 +00001523- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1524 operations on signed longs that are formally undefined by C.
1525 Unfortunately, at least one compiler now cares about that, so complicated
1526 the code to make that compiler happy again.
1527
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001528- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1529
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001530- Patch #1232023: Stop including current directory in search
1531 path on Windows.
1532
Neal Norwitze1fdb322006-07-21 05:32:28 +00001533- Fix some potential crashes found with failmalloc.
1534
Neal Norwitze7563102006-07-17 01:00:16 +00001535- Fix warnings reported by Klocwork's static analysis tool.
1536
Neal Norwitz84be93b2006-07-16 01:50:38 +00001537- Bug #1512814, Fix incorrect lineno's when code within a function
1538 had more than 255 blank lines.
1539
Georg Brandl9dceedb2006-07-12 15:31:17 +00001540- Patch #1521179: Python now accepts the standard options ``--help`` and
1541 ``--version`` as well as ``/?`` on Windows.
1542
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001543- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001544 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001545 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001546
Tim Peters112aad32006-07-19 00:03:19 +00001547- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001548 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001549 new ``sys._current_frames()`` returns a dictionary with one entry,
1550 mapping the faux "thread id" 0 to the current frame.
1551
Ronald Oussoren3075e162006-07-25 20:28:55 +00001552- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001553
Ronald Oussoren3075e162006-07-25 20:28:55 +00001554
Neal Norwitza1f10902006-07-12 07:28:29 +00001555Library
1556-------
1557
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001558- Correction of patch #1455898: In the mbcs decoder, set final=False
1559 for stream decoder, but final=True for the decode function.
1560
Georg Brandl07fec3a2006-08-01 18:49:24 +00001561- os.urandom no longer masks unrelated exceptions like SystemExit or
1562 KeyboardInterrupt.
1563
Tim Peters4643c2f2006-08-10 22:45:34 +00001564- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001565 shutil.copytree on Windows
1566
Georg Brandle34ac7c2006-07-30 11:07:23 +00001567- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1568 refers to file descriptors, not file objects.
1569
Tim Petersc10c9d02006-09-05 02:18:09 +00001570- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001571 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001572 #1513611, and probably others.
1573
Georg Brandledd9b0d2006-07-29 09:33:26 +00001574- Bug #1441397: The compiler module now recognizes module and function
1575 docstrings correctly as it did in Python 2.4.
1576
Tim Peters6f681472006-07-27 23:44:37 +00001577- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1578 lost that tests are sorted by name before being run. This rarely
1579 matters for well-written tests, but can create baffling symptoms if
1580 side effects from one test to the next affect outcomes. ``DocTestFinder``
1581 has been changed to sort the list of tests it returns.
1582
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001583- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001584 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001585
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001586- Bug #978833: Really close underlying socket in _socketobject.close.
1587
Georg Brandl8c036cc2006-08-20 13:15:39 +00001588- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1589 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001590
Georg Brandlcf0c1722006-07-26 07:23:32 +00001591- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1592 to recursive calls and call it with the failing package name.
1593
Martin v. Löwis0b483032006-07-25 09:53:12 +00001594- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1595
Georg Brandlc13c34c2006-07-24 14:09:56 +00001596- Patch #1515343: Fix printing of deprecated string exceptions with a
1597 value in the traceback module.
1598
Greg Ward48fae7a2006-07-23 16:05:51 +00001599- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1600
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001601- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1602
Brett Cannoncaebe222006-07-18 04:41:36 +00001603- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1604 argument tuple. For arguments where zero is illegal, the value is forced to
1605 the minimum value that is correct. This is to support an undocumented but
1606 common way people used to fill in inconsequential information in the time
1607 tuple pre-2.4.
1608
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001609- Patch #1220874: Update the binhex module for Mach-O.
1610
Barry Warsawb110bad2006-07-21 14:51:07 +00001611- The email package has improved RFC 2231 support, specifically for
1612 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1613 (name*0=<blah>) parameter continuations. This may change the types of
1614 values returned from email.message.Message.get_param() and friends.
1615 Specifically in some cases where non-encoded continuations were used,
1616 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1617 will just return the string (since non-encoded continuations don't have
1618 charset and language parts).
1619
1620 Also, whereas % values were decoded in all parameter continuations, they are
1621 now only decoded in encoded parameter parts.
1622
Ronald Oussoren3075e162006-07-25 20:28:55 +00001623- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1624
1625- Bug #1517996: IDLE now longer shows the default Tk menu when a
1626 path browser, class browser or debugger is the frontmost window on MacOS X
1627
Barry Warsaw00decd72006-07-27 23:43:15 +00001628- Patch #1520294: Support for getset and member descriptors in types.py,
1629 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1630 of an object against these built-in types and more importantly, for getting
1631 their docstrings printed in the interactive interpreter's help() function.

1636
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001637- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1638 a socket operation on a socket with a timeout, the exception will be
1639 caught correctly. Previously, the exception was not caught.
1640
Thomas Heller1393d6a2006-07-28 21:43:20 +00001641- Patch #1529514: The _ctypes extension is now compiled on more
1642 openbsd target platforms.
1643
Tim Peters9cab5932006-07-28 00:30:00 +00001644- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1645 a memory leak, affecting pickles and deep copies.
1646
Tim Petersbc24eee2006-07-27 01:14:53 +00001647- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001648 Paul Eggert.
1649
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001650- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1651
Thomas Hellerce049a02006-07-14 17:51:14 +00001652- Patch #1521817: Index range checking on ctypes arrays containing
1653 exactly one element enabled again. This allows iterating over these
1654 arrays, without the need to check the array size before.
1655
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001656- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001657 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001658 /dev/null in certain cases; this is now fixed.
1659
Thomas Heller47d7a062006-07-12 08:43:47 +00001660- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1661 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001662
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001663- Because of a misspelled preprocessor symbol, ctypes was always
1664 compiled without thread support; this is now fixed.
1665
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001666- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1667 methods now allow their database parameter to be None as the
1668 sleepycat API allows.
1669
Matt Flemingec926502006-07-28 11:27:27 +00001670- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1671 bluetooth API compared with Linux and FreeBSD.
1672
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001673Tests
1674-----
1675
1676- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1677 how long the test file should take to play. Now accepts taking 2.93 secs
1678 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1679
Georg Brandl4793aa32006-07-28 18:31:39 +00001680- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1681 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1682 run via ``regrtest.py``. Now they do.

1691
1692- PythonLauncher now works correctly when the path to the script contains
1693 characters that are treated specially by the shell (such as quotes).
1694
1695- Bug #1527397: PythonLauncher now launches scripts with the working directory
1696 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001697 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001698 expect.

1711
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001712- Bug #1501934: The scope of global variables that are locally assigned

Neal Norwitz28746ab2006-07-09 22:14:42 +00001727- On 64 bit systems, int literals that use less than 64 bits are
1728 now ints rather than longs.
1729
Neal Norwitzed657552006-07-10 00:04:44 +00001730- Bug #1512814, Fix incorrect lineno's when code at module scope
1731 started after line 256.
1732
Tim Peters32a83612006-07-10 21:08:24 +00001733- New function ``sys._current_frames()`` returns a dict mapping thread
1734 id to topmost thread stack frame. This is for expert use, and is
1735 especially useful for debugging application deadlocks. The functionality
1736 was previously available in Fazal Majid's ``threadframe`` extension
1737 module, but it wasn't possible to do this in a wholly threadsafe way from
1738 an extension.

1755
Thomas Woutersadd19112006-07-05 11:03:49 +00001756- string.Template() now correctly handles tuple-values. Previously,
1757 multi-value tuples would raise an exception and single-value tuples would
1758 be treated as the value they contain, instead.
1759
Martin v. Löwisede77f52006-07-03 13:01:35 +00001760- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1785
Brett Cannon53ab5b72006-06-22 16:49:14 +00001786- Bug #1510580: The 'warnings' module improperly required that a Warning
1787 category be either a types.ClassType and a subclass of Warning. The proper
1788 check is just that it is a subclass with Warning as the documentation states.
1789
Georg Brandlad29e632006-06-21 17:45:17 +00001790- The compiler module now correctly compiles the new try-except-finally
1791 statement (bug #1509132).
1792
Neal Norwitz60373cd2006-06-22 06:30:50 +00001793- The wsgiref package is now installed properly on Unix.

1797
Gerhard Häring762fbd32006-07-02 17:48:30 +00001798- The sqlite3 module did cut off data from the SQLite database at the first
1799 null character before sending it to a custom converter. This has been fixed
1800 now.

1803-----------------
1804
Tim Peters112aad32006-07-19 00:03:19 +00001805- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1806 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1807 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001808
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001809- Assigning None to pointer type fields in ctypes structures possible
1810 overwrote the wrong fields, this is fixed now.
1811
1812- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1813 on non-Windows platforms.
1814
1815- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1816 integer or long, without range checking.
1817
1818- Patch #1517790: It is now possible to use custom objects in the ctypes
1819 foreign function argtypes sequence as long as they provide a from_param
1820 method, no longer is it required that the object is a ctypes type.
1821
1822- The '_ctypes' extension module now works when Python is configured
1823 with the --without-threads option.
1824
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001825- Bug #1513646: os.access on Windows now correctly determines write

1840
Tim Peters32a83612006-07-10 21:08:24 +00001841- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001842 Previously, the slight difference could cause compilation errors of the
1843 'zlib' module on systems with more than one version of zlib.
1844
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001845- The MSI compileall step was fixed to also support a TARGETDIR

1876Core and builtins
1877-----------------
1878
Georg Brandla56b9152006-06-19 06:35:54 +00001879- Patch #1507676: Error messages returned by invalid abstract object operations
1880 (such as iterating over an integer) have been improved and now include the
1881 type of the offending object to help with debugging.
1882
Brett Cannonea3912b2006-06-13 21:46:41 +00001883- Bug #992017: A classic class that defined a __coerce__() method that returned
1884 its arguments swapped would infinitely recurse and segfault the interpreter.
1885
Neal Norwitz909eb122006-06-12 02:13:21 +00001886- Fix the socket tests so they can be run concurrently.
1887
Neal Norwitzb9845e72006-06-12 02:11:18 +00001888- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001889 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001890
Brett Cannon22565aa2006-06-09 22:31:23 +00001891- Bug #532646: object.__call__() will continue looking for the __call__
1892 attribute on objects until one without one is found. This leads to recursion
1893 when you take a class and set its __call__ attribute to an instance of the
1894 class. Originally fixed for classic classes, but this fix is for new-style.
1895 Removes the infinite_rec_3 crasher.
1896
Georg Brandl24250812006-06-09 18:45:48 +00001897- The string and unicode methods startswith() and endswith() now accept
1898 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1899
Brett Cannonde3b0522006-06-08 17:00:45 +00001900- Buffer objects, at the C level, never used the char buffer
1901 implementation even when the char buffer for the wrapped object was
1902 explicitly requested (originally returned the read or write buffer).
1903 Now a TypeError is raised if the char buffer is not present but is
1904 requested.
1905
Georg Brandlddbaa662006-06-04 21:56:52 +00001906- Patch #1346214: Statements like "if 0: suite" are now again optimized
1907 away like they were in Python 2.4.
1908
Georg Brandlb7c8f542006-05-27 12:30:25 +00001909- Builtin exceptions are now full-blown new-style classes instead of
1910 instances pretending to be classes, which speeds up exception handling
1911 by about 80% in comparison to 2.5a2.
1912
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001913- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1914 Unicode 4.1.
1915
Georg Brandlf4ef1162006-05-26 18:03:31 +00001916- Patch #921466: sys.path_importer_cache is now used to cache valid and
1917 invalid file paths for the built-in import machinery which leads to
1918 fewer open calls on startup.
1919
Tim Peters696cf432006-05-24 21:10:40 +00001920- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1921 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1922 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1923 the number of input digits (it was and remains linear-time for bases
1924 2, 4, 8, 16 and 32).
1925
Tim Petersb713ec22006-05-23 18:45:30 +00001926- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1927 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1928 an integer close to ``sys.maxint``. This was repaired by patch
1929 #1335972, which also gives a nice speedup.
1930
Richard Jonescebbefc2006-05-23 18:28:17 +00001931- Patch #1337051: reduced size of frame objects.
1932
1933- PyErr_NewException now accepts a tuple of base classes as its
1934 "base" parameter.
1935
Richard Jones7c88dcc2006-05-23 10:37:38 +00001936- Patch #876206: function call speedup by retaining allocated frame
1937 objects.
1938
Georg Brandl7b90e162006-05-18 07:01:27 +00001939- Bug #1462152: file() now checks more thoroughly for invalid mode
1940 strings and removes a possible "U" before passing the mode to the
1941 C library function.
1942
Neal Norwitz1004a532006-05-15 07:17:23 +00001943- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1944
Neal Norwitz373f0a72006-05-15 07:04:36 +00001945- Bug #1487966: Fix SystemError with conditional expression in assignment
1946
Martin v. Löwis879768d2006-05-11 13:28:43 +00001947- WindowsError now has two error code attributes: errno, which carries
1948 the error values from errno.h, and winerror, which carries the error
1949 values from winerror.h. Previous versions put the winerror.h values
1950 (from GetLastError()) into the errno attribute.
1951
Martin v. Löwis77736712006-05-04 05:51:03 +00001952- Patch #1475845: Raise IndentationError for unexpected indent.
1953
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001954- Patch #1479181: split open() and file() from being aliases for each other.
1955
Tim Peters44bd9862006-06-01 13:49:23 +00001956- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1957 methods were always silently ignored by dictionaries when comparing keys.
1958 They are now passed through (except when using the C API function
1959 ``PyDict_GetItem()``, whose semantics did not change).
1960
1961- Bug #1456209: In some obscure cases it was possible for a class with a
1962 custom ``__eq__()`` method to confuse dict internals when class instances
1963 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1964 No, you don't have any code that did this ;-)

1972
Brett Cannon6ee7d012006-06-08 16:23:04 +00001973- Change binascii.hexlify to accept a read-only buffer instead of only a char
1974 buffer and actually follow its documentation.
1975
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001976- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1977
Nick Coghlanc649ec52006-05-29 12:43:05 +00001978- Patch #1478788 (modified version): The functional extension module has
1979 been renamed to _functools and a functools Python wrapper module added.
1980 This provides a home for additional function related utilities that are
1981 not specifically about functional programming. See PEP 309.
1982
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001983- Patch #1493701: performance enhancements for struct module.

1988 copy() method.
1989
Andrew MacIntyre92913322006-06-13 15:04:24 +00001990- Patch #1454481: thread stack size is now tunable at runtime for thread
1991 enabled builds on Windows and systems with Posix threads support.
1992
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001993- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1994 (up to the system limit of 32K characters).
1995
1996- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1997 As a result, these functions now raise WindowsError instead of OSError.
1998
Tim Peters7a822da2006-05-25 21:50:17 +00001999- ``time.clock()`` on Win64 should use the high-performance Windows
2000 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
2001 Windows platforms).
2002
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002003- Calling Tk_Init twice is refused if the first call failed as that
2004 may deadlock.
2005
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00002006- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
2007 accept it without potentially using an uninitialized pointer.
2008
2009- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
2010 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
2011 patch numbers 1494885 and 1494902]

Gregory P. Smith372b5832006-06-05 18:48:21 +00002013- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00002014 [pybsddb project SF patch number 1466734]
2015
Gregory P. Smith372b5832006-06-05 18:48:21 +00002016- bsddb: fix DBCursor.pget() bug with keyword argument names when no data

2018
Gregory P. Smith3c228b12006-06-05 23:59:37 +00002019- bsddb: the __len__ method of a DB object has been fixed to return correct
2020 results. It could previously incorrectly return 0 in some cases.
2021 Fixes SF bug 1493322 (pybsddb bug 1184012).
2022
Gregory P. Smithff7d9912006-06-08 05:17:08 +00002023- bsddb: the bsddb.dbtables Modify method now raises the proper error and
2024 aborts the db transaction safely when a modifier callback fails.
2025 Fixes SF python patch/bug #1408584.
2026
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002027- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00002028 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002029 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
2030 database calls that would previously deadlock. [SF python bug #775414]

2061
Tim Peters43898b42006-06-14 04:09:25 +00002062- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2063 guarantee that adjacent triples in the return list always describe
2064 non-adjacent blocks. Previously, a pair of matching blocks could end
2065 up being described by multiple adjacent triples that formed a partition
2066 of the matching pair.

2075
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002076- The wsgiref package has been added to the standard library.
2077
Nick Coghlan676725d2006-06-08 13:54:49 +00002078- The functions update_wrapper() and wraps() have been added to the functools
2079 module. These make it easier to copy relevant metadata from the original
2080 function when writing wrapper functions.
2081
Tim Petersd6a9eef2006-06-05 01:48:21 +00002082- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2083 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002084
Martin v. Löwis3f767792006-06-04 19:36:28 +00002085- Patch #1359618: Speed up charmap encoder by using a trie structure
2086 for lookup.
2087
Tim Petersd609b1a2006-06-02 23:22:51 +00002088- The functions in the ``pprint`` module now sort dictionaries by key
2089 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2090 if and only if its display required more than one line, although that
2091 wasn't documented. The new behavior increases predictability; e.g.,
2092 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.

2115 stdout arguments, making it possible to redirect input and output
2116 for remote debugging.
2117
2118- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2119 a couple of issues, notably handling of long file names using the
2120 GNU LONGNAME extension.
2121
2122- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2123 new flag when ``name`` is already the name of an option flag.

2169Core and builtins
2170-----------------
2171
Thomas Heller1b046642006-04-18 18:51:06 +00002172- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2173 by converting these apis from macros into exported functions again:
2174
2175 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2176 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2177 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2178 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2179 PyRun_String Py_CompileString
2180
Martin v. Löwis45294a92006-04-18 06:24:08 +00002181- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2182
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002183- All uses of PyStructSequence_InitType have been changed to initialize
2184 the type objects only once, even if the interpreter is initialized
2185 multiple times.
2186
Neal Norwitz61546162006-04-14 05:20:28 +00002187- Bug #1454485, array.array('u') could crash the interpreter. This was
2188 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2189 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2190
2191- Py_UNICODE is unsigned. It was always documented as unsigned, but
2192 due to a bug had a signed value in previous versions.
2193
Tim Peters3a5e8b12006-04-11 01:44:07 +00002194- Patch #837242: ``id()`` of any Python object always gives a positive
2195 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2196 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002197 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002198 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002199
Tim Peters3a5e8b12006-04-11 01:44:07 +00002200 def __hash__(self):
2201 return id(self) # WRONG
2202
2203 because a hash result must be a (short) Python int but it was always
2204 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002205 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002206 was always usable as a hash value before this patch. That's no longer
2207 necessarily so.
2208
2209- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002210 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002211 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002212 #1454844)
2213
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002214- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2215 involving generators that have paused outside of any ``try`` or ``with``
2216 blocks. (In 2.5a1, a paused generator that was part of a reference
2217 cycle could not be garbage collected, regardless of whether it was
2218 paused in a ``try`` or ``with`` block.)

2252 or exception is ignored).
2253
Nick Coghlanda2268f2006-04-24 04:37:15 +00002254- Fixed contextlib.nested to cope with exceptions being raised and
2255 caught inside exit handlers.
2256
Greg Wardab05edc2006-04-23 03:47:58 +00002257- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2258 hex, octal, or binary; add ``append_const`` action; keep going if
2259 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2260 added ``epilog`` for better help generation).
2261
Tim Peters21fbd572006-04-21 21:18:10 +00002262- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2263 called from a thread spawned as a side effect of importing a module.
2264
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002265- The pydoc module now supports documenting packages contained in
2266 .zip or .egg files.
2267
2268- The pkgutil module now has several new utility functions, such
2269 as ``walk_packages()`` to support working with packages that are either
2270 in the filesystem or zip files.
2271
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002272- The mailbox module can now modify and delete messages from
2273 mailboxes, in addition to simply reading them. Thanks to Gregory
2274 K. Johnson for writing the code, and to the 2005 Google Summer of
2275 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002276
Tim Petersc7605f22006-04-17 21:12:33 +00002277- The ``__del__`` method of class ``local`` in module ``_threading_local``
2278 returned before accomplishing any of its intended cleanup.
2279
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002280- Patch #790710: Add breakpoint command lists in pdb.

2323 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2324 and "%zu" for unsigned integers of type ``size_t``.

2327-----
2328
Nick Coghlanda2268f2006-04-24 04:37:15 +00002329- test_contextlib now checks contextlib.nested can cope with exceptions
2330 being raised and caught inside exit handlers.
2331
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002332- test_cmd_line now checks operation of the -m and -c command switches
2333
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002334- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2335 it separately and by hand. It also wasn't cleaning up its changes to
2336 the current Decimal context.
2337
Thomas Woutersabd08882006-04-26 15:53:30 +00002338- regrtest.py now has a -M option to run tests that test the new limits of
2339 containers, on 64-bit architectures. Running these tests is only sensible
2340 on 64-bit machines with more than two gigabytes of memory. The argument
2341 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002349Documentation
2350-------------
2351
Tim Petersb06d28c2006-05-12 01:57:59 +00002352- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2353
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002354- PEP 343: Added Context Types section to the library reference
2355 and attempted to bring other PEP 343 related documentation into
2356 line with the implementation and/or python-dev discussions.
2357
Tim Peters8dc73d22006-04-24 02:03:16 +00002358- Bug #1337990: clarified that ``doctest`` does not support examples
2359 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002362What's New in Python 2.5 alpha 1?
2363=================================
2364
Anthony Baxterebed3f62006-04-03 15:03:44 +00002365*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002366
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002367Core and builtins
2368-----------------
2369
Nick Coghlan43832302006-04-23 17:04:07 +00002370- PEP 338: -m command line switch now delegates to runpy.run_module
2371 allowing it to support modules in packages and zipfiles
2372
Martin v. Löwisc661b882006-04-20 04:54:23 +00002373- On Windows, .DLL is not an accepted file name extension for
2374 extension modules anymore; extensions are only found if they
2375 end in .PYD.
2376
Martin v. Löwisea62d252006-04-03 10:56:49 +00002377- Bug #1421664: sys.stderr.encoding is now set to the same value as
2378 sys.stdout.encoding.
2379
Neal Norwitz92e212f2006-04-03 04:48:37 +00002380- __import__ accepts keyword arguments.
2381
Georg Brandlccadf842006-03-31 18:54:53 +00002382- Patch #1460496: round() now accepts keyword arguments.
2383
Anthony Baxter262c00a2006-03-30 10:53:17 +00002384- Fixed bug #1459029 - unicode reprs were double-escaped.
2385
Hye-Shik Changd478f342006-03-23 12:32:36 +00002386- Patch #1396919: The system scope threads are reenabled on FreeBSD
2387 5.4 and later versions.
2388
Neal Norwitze98ccf62006-03-23 05:39:47 +00002389- Bug #1115379: Compiling a Unicode string with an encoding declaration
2390 now gives a SyntaxError.
2391
Georg Brandlabd1ff82006-03-18 07:59:59 +00002392- Previously, Python code had no easy way to access the contents of a
2393 cell object. Now, a ``cell_contents`` attribute has been added
2394 (closes patch #1170323).
2395
Tim Peterscf79aac2006-03-16 01:14:46 +00002396- Patch #1123430: Python's small-object allocator now returns an arena to
2397 the system ``free()`` when all memory within an arena becomes unused
2398 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2399 freed. Some applications will see a drop in virtual memory size now,
2400 especially long-running applications that, from time to time, temporarily
2401 use a large number of small objects. Note that when Python returns an
2402 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002403 platform C library will in turn return that memory to the operating system.
2404 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002405 appears to be effective at least on Microsoft C and gcc-based systems.
2406 Thanks to Evan Jones for hard work and patience.
2407
Georg Brandl533ff6f2006-03-08 18:09:27 +00002408- Patch #1434038: property() now uses the getter's docstring if there is
2409 no "doc" argument given. This makes it possible to legitimately use
2410 property() as a decorator to produce a read-only property.
2411
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002412- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2413 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2414 of requiring an int or long in slicing and a few other contexts, enabling
2415 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2416
Neal Norwitz995acdf2006-03-07 05:01:00 +00002417- Fixed various bugs reported by Coverity's Prevent tool.
2418
Brett Cannonbf364092006-03-01 04:25:17 +00002419- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2420 new exception base class, BaseException, which has a new message attribute.
2421 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2422 Raising a string exception now raises a DeprecationWarning.
2423
Thomas Woutersfb609f42006-02-28 16:37:25 +00002424- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2425 explicitly relative, using 'from .module import name' to mean 'from the same
2426 package as this module is in. Imports without dots still default to the
2427 old relative-then-absolute, unless 'from __future__ import
2428 absolute_import' is used.
2429
Brett Cannona7446e32006-02-27 23:39:10 +00002430- Properly check if 'warnings' raises an exception (usually when a filter set
2431 to "error" is triggered) when raising a warning for raising string
2432 exceptions.
2433
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002434- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002435 The name was removed from Include/code.h.
2436
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002437- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002438
Guido van Rossum1968ad32006-02-25 22:38:04 +00002439- Patch 1433928:
2440 - The copy module now "copies" function objects (as atomic objects).
2441 - dict.__getitem__ now looks for a __missing__ hook before raising
2442 KeyError.
2443
Tim Peters84ef21c2006-02-28 20:39:06 +00002444- PEP 343: with statement implemented. Needs ``from __future__ import
2445 with_statement``. Use of 'with' as a variable will generate a warning.
2446 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002447 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002448 The following objects have __context__ methods:
2449 - The built-in file type.
2450 - The thread.LockType type.
2451 - The following types defined by the threading module:
2452 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2453 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002454
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002455- Fix the encodings package codec search function to only search
2456 inside its own package. Fixes problem reported in patch #1433198.
2457
2458 Note: Codec packages should implement and register their own
2459 codec search function. PEP 100 has the details.
2460
Tim Peters9ea89d22006-06-04 03:26:02 +00002461- PEP 353: Using ``Py_ssize_t`` as the index type.
2462
2463- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2464 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2465 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2466 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2467 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002468
Neal Norwitzfc76d632006-01-10 06:03:13 +00002469- Patch #1400181, fix unicode string formatting to not use the locale.
2470 This is how string objects work. u'%f' could use , instead of .
2471 for the decimal point. Now both strings and unicode always use periods.
2472
Neal Norwitz671b9e32006-01-09 07:07:12 +00002473- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2474 configure would break checking curses.h.
2475
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002476- Bug #959576: The pwd module is now builtin. This allows Python to be
2477 built on UNIX platforms without $HOME set.
2478
Neal Norwitzc10978f2005-12-19 06:07:16 +00002479- Bug #1072182, fix some potential problems if characters are signed.
2480
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002481- Bug #889500, fix line number on SyntaxWarning for global declarations.
2482
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002483- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2484
Neal Norwitze7214a12005-12-18 05:03:17 +00002485- Support for converting hex strings to floats no longer works.
2486 This was not portable. float('0x3') now raises a ValueError.
2487
Barry Warsaw2a38a862005-12-18 01:27:35 +00002488- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002489 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002490 is now displayed in interactive prompt banner.
2491
Georg Brandlfa166682005-12-17 21:45:17 +00002492- Implementation of PEP 341 - Unification of try/except and try/finally.
2493 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002494 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002495
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002496- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2497 now encodes backslash correctly.
2498
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002499- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2500
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002501- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002502 and long longs.
2503
Neal Norwitz67715f02005-11-09 06:59:35 +00002504- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002505 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002506 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002507
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002508- Replaced most Unicode charmap codecs with new ones using the
2509 new Unicode translate string feature in the builtin charmap
2510 codec; the codecs were created from the mapping tables available
2511 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2512 encodings now include a mapping for the Apple logo)
2513
Tim Peterse3547fd2005-12-16 23:13:57 +00002514- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002515
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002516- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002517
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002518- A new AST parser implementation was completed. The abstract
2519 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002520 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002521
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002522- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002523 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2524
Neal Norwitz708e51a2005-10-03 04:48:15 +00002525- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2526
Neal Norwitz11bd1192005-10-03 00:54:56 +00002527- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2528 Provide a warning when a directory is passed on the command line.
2529
Neal Norwitz40d37812005-10-02 01:48:49 +00002530- Fix segfault with invalid coding.
2531
2532- SF bug #772896: unknown encoding results in MemoryError.
2533
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002534- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002535 supported a __len__() method which evaluated to False when the iterator
2536 was empty.
2537
Guido van Rossum630db602005-09-20 18:49:54 +00002538- On 64-bit platforms, when __len__() returns a value that cannot be
2539 represented as a C int, raise OverflowError.
2540
Skip Montanarof8948ca2005-09-19 03:54:46 +00002541- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002542 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002543
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002544- SF bug #893549: parsing keyword arguments was broken with a few format
2545 codes.
2546
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002547- Changes donated by Elemental Security to make it work on AIX 5.3
2548 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2549 bug #105470: test_pwd fails on 64bit system (Opteron).
2550
Guido van Rossum539c6622005-09-14 17:49:54 +00002551- Changes donated by Elemental Security to make it work on HP-UX 11 on
2552 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2553
Georg Brandl4550b8d2005-08-26 06:43:52 +00002554- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002555 (fixes bug #1119418).
2556
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002557- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2558
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002559- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2560 exceptions that cause a function to exit.
2561
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002562- The implementation of set() and frozenset() was revised to use its
2563 own internal data structure. Memory consumption is reduced by 1/3
2564 and there are modest speed-ups as well. The API is unchanged.
2565
Tim Petersde7990b2005-07-17 23:45:23 +00002566- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2567
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002568- SF bug #1229429: PyObject_CallMethod failed to decrement some
2569 reference counts in some error exit cases.
2570
Tim Petersecc6e6a2005-07-10 22:30:55 +00002571- SF bug #1185883: Python's small-object memory allocator took over
2572 a block managed by the platform C library whenever a realloc specified
2573 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002574 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002575 portable way to copy data from the C-managed block into Python's
2576 small-object space without risking a memory fault. Python's small-object
2577 realloc now leaves such blocks under the control of the platform C
2578 realloc.
2579
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002580- SF bug #1232517: An overflow error was not detected properly when
2581 attempting to convert a large float to an int in os.utime().
2582
Raymond Hettinger3296e692005-06-29 23:29:56 +00002583- SF bug #1224347: hex longs now print with lowercase letters just
2584 like their int counterparts.
2585
Michael W. Hudson188d4362005-06-20 16:52:57 +00002586- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2587 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2588 interpreter states; back out that fix and do a better job (see
2589 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2590 for a longer write-up of the problem).
2591
Michael W. Hudsondf888462005-06-03 14:41:55 +00002592- SF patch #1180995: marshal now uses a binary format by default when
2593 serializing floats.
2594
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002595- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2596 the routines that promise to produce IEEE 754 binary representations
2597 of floats now simply copy bytes around.
2598
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002599- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2600 278.
2601
Brett Cannonc3647ac2005-04-26 03:45:26 +00002602- patch #1109424: int, long, float, complex, and unicode now check for the
2603 proper magic slot for type conversions when subclassed. Previously the
2604 magic slot was ignored during conversion. Semantics now match the way
2605 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002606 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002607 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002608 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002609
Barry Warsawc8d907c2005-04-19 23:43:40 +00002610- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2611 NULL, now raise an AttributeError when attempting to set or delete the
2612 attribute. Previously a TypeError was raised, but this was inconsistent
2613 with the equivalent pure-Python implementation.
2614
Michael W. Hudson774479c2005-04-18 08:46:17 +00002615- It is now safe to call PyGILState_Release() before
2616 PyEval_InitThreads() (note that if there is reason to believe there
2617 are multiple threads around you still must call PyEval_InitThreads()
2618 before using the Python API; this fix is for extension modules that
2619 have no way of knowing if Python is multi-threaded yet).
2620
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002621- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2622 disabled caused a crash.
2623
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002624- Bug #1165306: instancemethod_new allowed the creation of a method
2625 with im_class == im_self == NULL, which caused a crash when called.
2626
Tim Petersecc6e6a2005-07-10 22:30:55 +00002627- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002628 fixes the crash seen in bug #1165761
2629
Raymond Hettinger96229b12005-03-11 06:49:40 +00002630- Added two new builtins, any() and all().
2631
Brett Cannon409d8f22005-03-05 06:47:57 +00002632- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002633 (e.g., ``class C(): pass`` is no longer a syntax error).
2634 Patch #1176012 added support to the 'parser' module and 'compiler' package
2635 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002636
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002637- Patch #1115086: Support PY_LONGLONG in structmember.
2638
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002639- Bug #1155938: new style classes did not check that __init__() was
2640 returning None.
2641
Tim Petersecc6e6a2005-07-10 22:30:55 +00002642- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002643 ('\') with a specific error message.
2644
Martin v. Löwisff232d72005-03-03 09:24:38 +00002645- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2646
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002647- Bug #1124295: the __name__ attribute of file objects was
2648 inadvertently made inaccessible in restricted mode.
2649
Tim Petersecc6e6a2005-07-10 22:30:55 +00002650- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002651 an ferror() call.
2652
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002653- min() and max() now support key= arguments with the same meaning as in
2654 list.sort().
2655
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002656- The peephole optimizer now performs simple constant folding in expressions:
2657 (2+3) --> (5).
2658
Raymond Hettingera422c342005-01-11 03:03:27 +00002659- set and frozenset objects can now be marshalled. SF #1098985.
2660
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002661- Bug #1077106: Poor argument checking could cause memory corruption
2662 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002663
Jeremy Hyltonab630502005-02-04 18:44:06 +00002664- The parser did not complain about future statements in illegal
2665 positions. It once again reports a syntax error if a future
2666 statement occurs after anything other than a doc string.
2667
Neil Schemenauercf52c072005-08-12 17:34:58 +00002668- Change the %s format specifier for str objects so that it returns a
2669 unicode instance if the argument is not an instance of basestring and
2670 calling __str__ on the argument returns a unicode instance.
2671
Tim Petersf4e69282006-02-27 17:15:31 +00002672- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2673 current thread state when the auto-GIL-state machinery knows about
2674 it (since the thread state is being deleted, continuing to remember it
2675 can't help, but can hurt if another thread happens to get created with
2676 the same thread id).
2677

2706 for applications that require this specific version (such as IDNA).
2707
Neal Norwitzb62c4332006-03-04 18:35:47 +00002708- The timing module is no longer built by default. It was deprecated

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002868- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2869 been renamed to have only a single underscore prefix. This was done to
2870 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002871
Nick Coghlan43832302006-04-23 17:04:07 +00002872- PEP 338: new module runpy defines a run_module function to support
2873 executing modules which provide access to source code or a code object
2874 via the PEP 302 import mechanisms.
2875
Anthony Baxter93f5b932006-04-03 08:05:07 +00002876- The email module's parsedate_tz function now sets the daylight savings

2884 in attribute values.
2885
Anthony Baxterc51ee692006-04-01 00:57:31 +00002886- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002887 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002888 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002889 module will not be built.
2890
Tim Petersc17976e2006-04-01 00:26:53 +00002891- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2892 aren't officially supported here, and trying to use them will probably
2893 raise an exception some day. But dicts have been allowed, and "mostly
2894 worked", so support for them won't go away without warning.
2895
Georg Brandl338ef7d2006-03-31 18:42:16 +00002896- Bug #1445068: getpass.getpass() can now be given an explicit stream

2914
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002915- email 4.0 package now integrated. This is largely the same as the email 3.0
2916 package that was included in Python 2.3, except that PEP 8 module names are
2917 now used (e.g. mail.message instead of email.Message). The MIME classes
2918 have been moved to a subpackage (e.g. email.mime.text instead of
2919 email.MIMEText). The old names are still supported for now. Several
2920 deprecated Message methods have been removed and lots of bugs have been
2921 fixed. More details can be found in the email package documentation.
2922
Walter Dörwald40108c92006-03-27 08:15:44 +00002923- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2924 (a subclass of tuple) that provides incremental decoders and encoders
2925 (a way to use stateful codecs without the stream API). Python functions
2926 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2927 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2928 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002930- Patch #1359365: Calling next() on a closed StringIO.String object raises
2931 a ValueError instead of a StopIteration now (like file and cString.String do).
2932 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2933 called before (like file and StringIO.StringIO do).

3008 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
3009 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
3010 Ronald L. Rivest offered this advice for Python:
3011
3012 "The consensus of researchers in this area (at least as
3013 expressed at the NIST Hash Function Workshop 10/31/05),
3014 is that SHA-256 is a good choice for the time being, but
3015 that research should continue, and other alternatives may
3016 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00003017
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00003018- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl268e61c2005-06-03 14:28:50 +00003120- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
3121 component of the path.
3122
Skip Montanaro174dd222005-05-14 20:54:16 +00003123- Patch #1120353: The xmlrpclib module provides better, more transparent,
3124 support for datetime.{datetime,date,time} objects. With use_datetime set
3125 to True, applications shouldn't have to fiddle with the DateTime wrapper
3126 class at all.
3127
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00003128- distutils.commands.upload was added to support uploading distribution
3129 files to PyPI.
3130
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00003131- distutils.commands.register now encodes the data as UTF-8 before posting
3132 them to PyPI.
3133
Raymond Hettinger267b8682005-03-27 10:47:39 +00003134- decimal operator and comparison methods now return NotImplemented
3135 instead of raising a TypeError when interacting with other types. This
3136 allows other classes to implement __radd__ style methods and have them
3137 work as expected.
3138
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003139- Bug #1163325: Decimal infinities failed to hash. Attempting to
3140 hash a NaN raised an InvalidOperation instead of a TypeError.
3141
Tim Petersecc6e6a2005-07-10 22:30:55 +00003142- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00003143 stream compression; add, for symmetry reasons, r:* as a synonym of r.
3144
Martin v. Löwis00a73e72005-03-04 19:40:34 +00003145- Patch #1043890: Add extractall method to tarfile.
3146
Martin v. Löwisc72dd382005-03-04 13:50:17 +00003147- Patch #1075887: Don't require MSVC in distutils if there is nothing
3148 to build.
3149
Martin v. Löwis637431b2005-03-03 23:12:42 +00003150- Patch #1103407: Properly deal with tarfile iterators when untarring
3151 symbolic links on Windows.
3152
Tim Petersecc6e6a2005-07-10 22:30:55 +00003153- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00003154 profile.py if available.
3155
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00003156- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
3157
Martin v. Löwisc5574e82005-03-03 10:57:37 +00003158- Patch #1117454: Remove code to special-case cookies without values
3159 in LWPCookieJar.
3160
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00003161- Patch #1117339: Add cookielib special name tests.
3162
Martin v. Löwise869eb12005-03-03 09:46:07 +00003163- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
3164
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00003165- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
3166
Martin v. Löwisdf241532005-03-03 08:17:42 +00003167- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
3168
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00003169- Patch #1104111: Alter setup.py --help and --help-commands.
3170
Martin v. Löwis4afe1542005-03-01 08:09:28 +00003171- Patch #1121234: Properly cleanup _exit and tkerror commands.
3172
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00003173- Patch #1049151: xdrlib now unpacks booleans as True or False.
3174
Raymond Hettingerbab41432005-02-05 01:31:19 +00003175- Fixed bug in a NameError bug in cookielib. Patch #1116583.
3176
Guido van Rossumd0641422005-02-03 15:01:24 +00003177- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3178 disables recursive traversal through instance attributes, which can
3179 be exploited in various ways.
3180
Tim Peterse3547fd2005-12-16 23:13:57 +00003181- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003182 flags on the HTTP listening socket.
3183
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003184- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3185 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3186
Fred Drakefbdeaad2006-07-29 16:56:15 +00003187- Patches #893642, #1039083: add allow_none, encoding arguments to
3188 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003189
Martin v. Löwis1d11de62005-01-29 13:29:23 +00003190- Bug #1110478: Revert os.environ.update to do putenv again.
3191
Thomas Hellerd6c6e222005-01-20 19:20:16 +00003192- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3193
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003194- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3195
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003196- Enhancements to the csv module:
3197
3198 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003199 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003200 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003201 + Dialect parameter parsing has been re-implemented to improve error
3202 reporting.
3203 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3204 dictates.
3205 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003206 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003207 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003208 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3209 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003210 + reader now allows \r characters to be quoted (previously it only allowed
3211 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003212 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003213 + Dialect classes passed to the module are no longer instantiated by
3214 the module before being parsed (the former validation scheme required
3215 this, but the mechanism was unreliable).
3216 + The dialect registry now contains instances of the internal
3217 C-coded dialect type, rather than references to python objects.
3218 + the internal c-coded dialect type is now immutable.
3219 + register_dialect now accepts the same keyword dialect specifications
3220 as the reader and writer, allowing the user to register dialects
3221 without first creating a dialect class.
3222 + a configurable limit to the size of parsed fields has been added -
3223 previously, an unmatched quote character could result in the entire
3224 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003225 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003226 the parser field size limit (returning the former limit). The initial
3227 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003228 + A line_num attribute has been added to the reader object, which tracks
3229 the number of lines read from the source iterator. This is not
3230 the same as the number of records returned, as records can span
3231 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003232 + reader and writer objects were not being registered with the cyclic-GC.
3233 This has been fixed.
3234
Brett Cannone6539c42005-01-08 02:43:53 +00003235- _DummyThread objects in the threading module now delete self.__block that is
3236 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3237 lock primitives tend to be limited in number and thus should not be wasted on
3238 a _DummyThread object. Fixes bug #1089632.
3239
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003240- The imghdr module now detects Exif files.
3241
Raymond Hettinger6065d322004-12-20 23:51:53 +00003242- StringIO.truncate() now correctly adjusts the size attribute.
3243 (Bug #951915).
3244
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003245- locale.py now uses an updated locale alias table (built using
3246 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3247 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003248 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003249
Raymond Hettinger3557f422004-12-07 12:02:02 +00003250- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3251
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003252- the pickle module no longer accepts the deprecated None option in the
3253 args tuple returned by __reduce__().
3254
Brett Cannon84667c02004-12-07 03:25:18 +00003255- optparse now optionally imports gettext. This allows its use in setup.py.
3256
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003257- the pickle module no longer uses the deprecated bin parameter.
3258
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003259- the shelve module no longer uses the deprecated binary parameter.
3260
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003261- the pstats module no longer uses the deprecated ignore() method.
3262
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003263- the filecmp module no longer uses the deprecated use_statcache argument.
3264
Raymond Hettinger664347b2004-12-04 21:21:53 +00003265- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3266 extended or overridden by subclasses. Formerly, the subclassed method would
3267 be ignored by the rest of the module. (Bug #1078905).
3268
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003269- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003270 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003271
Walter Dörwald36733692004-12-22 12:50:50 +00003272- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3273 once when a size argument is given. This prevents a buffer overflow in the
3274 tokenizer with very long source lines.
3275
Barry Warsaw538561e2006-01-01 21:48:54 +00003276- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3277 immediately after creating the object, without any intervening
3278 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003279
Skip Montanaro05885812005-01-16 20:48:27 +00003280- The reconvert.quote function can now emit triple-quoted strings. The
3281 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003282
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003283- ``UserString.MutableString`` now supports negative indices in
3284 ``__setitem__`` and ``__delitem__``
3285
Greg Ward40407942005-03-05 02:53:17 +00003286- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3287 correctly.
3288
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003289- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3290 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3291 character even if the user has passed a size parameter to get a proper
3292 line ending. Remove the special handling of a "\r\n" that has been split
3293 between two lines.
3294
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003295- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3296 about illegal code points. The codec now supports PEP 293 style error
3297 handlers.
3298
Walter Dörwald78a78b02005-09-01 12:04:29 +00003299- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003300 from the input stream, so that the output is a byte string in the correct
3301 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003302
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003303- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3304 considering it exactly like a '*'.
3305
Walter Dörwald007f8df2005-10-09 19:42:27 +00003306- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3307 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003308
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003309- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3310
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003311- Patch #1413711: Certain patterns of differences were making difflib
3312 touch the recursion limit.
3313
Walter Dörwald58917a62006-03-31 15:26:22 +00003314- Bug #947906: An object oriented interface has been added to the calendar
3315 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003316 called as a script (e.g. via ``python -mcalendar``). Localized month and
3317 weekday names can be ouput (even if an exotic encoding is used) using
3318 special classes that use unicode.

3321-----
3322
Neal Norwitz602d3392006-03-31 08:21:40 +00003323- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3324 by using -mieee gcc option.
3325
Martin v. Löwis86d66262006-02-17 08:40:11 +00003326- Patch #1432345: Make python compile on DragonFly.
3327
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003328- Build support for Win64-AMD64 was added.
3329
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003330- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3331
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003332- Patch #881820: look for openpty and forkpty also in libbsd.
3333
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003334- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3335 The zlib module is now builtin on Windows.
3336
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003337- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3338
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003339- Bug #1189330: configure did not correctly determine the necessary
3340 value of LINKCC if python was built with GCC 4.0.
3341
Trent Mick8321b422005-07-26 02:29:21 +00003342- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3343 vulnerability in zlib 1.2.1 and 1.2.2.
3344
Brett Cannon08cd5982005-04-24 22:26:38 +00003345- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3346 flags that change binary compatibility. Changes were also made to
3347 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003348 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003349
Bob Ippolitoed233462005-03-29 13:47:59 +00003350- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3351 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3352 no longer exists). This configure patch makes things right.
3353
Martin v. Löwise2713be2005-03-08 15:03:08 +00003354- Bug #1158607: Build with --disable-unicode again.
3355
Brett Cannon46d96232005-02-16 00:07:19 +00003356- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3357 defined. Discovered as a result of not being able to build on OS X.
3358
Brett Cannon516592f2004-12-07 00:42:59 +00003359- setup.py now uses the directories specified in LDFLAGS using the -L option
3360 and in CPPFLAGS using the -I option for adding library and include
3361 directories, respectively, for compiling extension modules against. This has
3362 led to the core being compiled using the values in CPPFLAGS. It also removes
3363 the need for the special-casing of both DarwinPorts and Fink for darwin since
3364 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3365 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3366 Fink, ``-I/opt/local/include`` for DarwinPorts).
3367
Brett Cannon43802422005-02-10 20:48:03 +00003368- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3369 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3370 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3371 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003373C API
3374-----
3375
Tim Petersc9d78aa2006-03-26 23:27:58 +00003376- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3377 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3378 is obtained via the ``PyObject_`` family, it must be released via the
3379 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3380 always been officially true, but when Python's small-object allocator was
3381 introduced, an attempt was made to cater to a few extension modules
3382 discovered at the time that obtained memory via ``PyObject_New`` but
3383 released it via ``PyMem_DEL``. It's years later, and if such code still
3384 exists it will fail now (probably with segfaults, but calling wrong
