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 Heimese93237d2007-12-19 02:37:44 +000015- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE
16 and Py_REFCNT.
17
Christian Heimes0a8143f2007-12-18 23:22:54 +000018- Issue #1635: Platform independent creation and representation of NaN
19 and INF. float("nan"), float("inf") and float("-inf") now work on every
20 platform with IEEE 754 semantics.
21
22- Added case insensitive comparsion methods ``PyOS_stricmp(char*, char*)``
23 and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
24
Raymond Hettingerfd7ed402007-12-18 21:24:09 +000025- Compiler now generates simpler and faster code for dictionary literals.
26 The oparg for BUILD_MAP now indicates an estimated dictionary size.
27 There is a new opcode, STORE_MAP, for adding entries to the dictionary.
28
Christian Heimesdb3d6cb2007-12-16 21:39:43 +000029- Issue #1638: %zd configure test fails on Linux
30
Christian Heimes90e10e72007-12-14 02:35:23 +000031- Issue #1620: New property decorator syntax was modifying the decorator
32 in place instead of creating a new decorator object.
33
Christian Heimes284d9272007-12-10 22:28:56 +000034- Issue #1580: New free format floating point representation based on
35 "Floating-Point Printer Sample Code", by Robert G. Burger. For example
36 repr(11./5) now returns '2.2' instead of '2.2000000000000002'.
37
Skip Montanaro26015492007-12-08 15:33:24 +000038- Issue #1538: Avoid copying string in split/rsplit if the split
39 char is not found.
40
Andrew M. Kuchling395fe442007-12-05 13:27:20 +000041- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +000042 SystemError.
43
Nick Coghlanef01d822007-12-03 12:55:17 +000044- PEP 366: Allow explicit relative imports when executing modules
45 inside packages with the -m switch via a new module level
46 __package__ attribute.
47
Christian Heimesdfdfaab2007-12-01 11:20:10 +000048- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
49 ``PyFloat_GetInfo()`` to the float API.
50
Amaury Forgeot d'Arcdafd32b2007-11-30 20:51:40 +000051- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
52 format code incorrectly truncated the length to an int, even when
53 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
54 results with huge strings.
55
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +000056- Issue #1402: Fix a crash on exit, when another thread is still running, and
57 if the deallocation of its frames somehow calls the PyGILState_Ensure() /
58 PyGILState_Release() functions.
59
Christian Heimes28104c52007-11-27 23:16:44 +000060- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
61
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +000062- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
63 attribute of an empty cell object.
64
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +000065- Issue #1460: The utf-7 incremental decoder did not accept truncated input.
66 It now correctly saves its state between chunks of data.
67
Nick Coghlan327a39b2007-11-18 11:56:28 +000068- Patch #1739468: Directories and zipfiles containing a __main__.py file can
69 now be directly executed by passing their name to the interpreter. The
70 directory/zipfile is automatically inserted as the first entry in sys.path.
71
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +000072- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
73 generator expression when at the same time the executed code is closing a
74 paused generator.
75
Raymond Hettinger1760c8a2007-11-08 02:52:43 +000076- sets and frozensets now have an isdisjoint() method.
77
Raymond Hettinger3f8caa32007-10-24 01:28:33 +000078- optimize the performance of builtin.sum().
79
Neal Norwitz44f326e2007-10-05 05:29:17 +000080- Fix warnings found by the new version of the Coverity checker.
81
Raymond Hettinger8f669372007-10-03 21:18:11 +000082- The enumerate() builtin function is no longer bounded to sequences smaller
83 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
84 shifts from ints to longs.
85
Brett Cannon0b14f242007-09-30 19:45:10 +000086- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
87 having a self-referential tuple, which is possible from C code. Nor did
88 object's tp_str consider that a type's tp_str could do something that could
89 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
90 respectively, fixed the issues.
91
Brett Cannon01531592007-09-17 03:28:34 +000092- Issue #1164: It was possible to trigger deadlock when using the 'print'
93 statement to write to a file since the GIL was not released as needed. Now
94 PyObject_Print() does the right thing along with various tp_print
95 implementations of the built-in types and those in the collections module.
96
Brett Cannon4c20bc42007-09-11 21:02:28 +000097- Issue #1147: Exceptions were directly allowing string exceptions in their
98 throw() method even though string exceptions no longer allowed.
99
Brett Cannona0c05512007-09-10 21:38:27 +0000100- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
101 list by using the recursion counter.
102
Brett Cannon1e534b52007-09-07 04:18:30 +0000103- Issue #1202533: Fix infinite recursion calls triggered by calls to
104 PyObject_Call() never calling back out to Python code to trigger recursion
105 depth updates/checks. Required the creation of a static RuntimeError
106 instance in case normalizing an exception put the recursion check value past
107 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
108
Martin v. Löwisa5136192007-09-04 14:19:28 +0000109- Patch #1031213: Decode source line in SyntaxErrors back to its original source
110 encoding.
111
Neal Norwitz766d8802007-08-03 06:46:29 +0000112- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
113
Martin v. Löwis68192102007-07-21 06:55:02 +0000114- PEP 3123: Provide forward compatibility with Python 3.0, while keeping
115 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
116 PyVarObject_HEAD_INIT.
117
Georg Brandl7c3b50d2007-07-12 08:38:00 +0000118- Patch #1673759: add a missing overflow check when formatting floats
119 with %G.
120
Martin v. Löwis6371cd82007-06-09 07:42:52 +0000121- Patch #1733960: Allow T_LONGLONG to accept ints.
122
Walter Dörwald84a3efe2007-06-13 16:57:12 +0000123- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
124
Neal Norwitzdb2b1b32007-06-11 07:36:24 +0000125- Prevent expandtabs() on string and unicode objects from causing a segfault
126 when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +0000127
Martin v. Löwisda587ab2007-06-08 17:29:20 +0000128- Bug #1733488: Fix compilation of bufferobject.c on AIX.
129
Georg Brandl25497a12007-06-01 19:20:27 +0000130- Bug #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +0000131
Neal Norwitz0ac60192007-05-27 04:08:54 +0000132- Add new attribute names for function objects. All the func_* become
133 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
134
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +0000135- Add -3 option to the interpreter to warn about features that are
136 deprecated and will be changed/removed in Python 3.0.
137
Georg Brandl2134e752007-05-21 20:34:16 +0000138- Patch #1686487: you can now pass any mapping after '**' in function
139 calls.
140
Collin Winter62903052007-05-18 23:11:24 +0000141- except clauses may now be spelled either "except E, target:" or
142 "except E as target:". This is to provide forwards compatibility with
143 Python 3.0.
144
Brett Cannon229cee22007-05-05 01:34:02 +0000145- Deprecate BaseException.message as per PEP 352.
146
Armin Rigo9790a272007-05-02 19:23:31 +0000147- Bug #1303614: don't expose object's __dict__ when the dict is
148 inherited from a builtin base.
149
Vinay Sajip8549ce32007-05-06 17:53:37 +0000150- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +0000151 setting a plain string, ie don't expand to single letter identifiers.
152
Raymond Hettinger13936692007-04-11 18:40:58 +0000153- Request #1191699: Slices can now be pickled.
154
Raymond Hettinger4db5fe92007-04-12 04:10:00 +0000155- Request #1193128: str.translate() now allows a None argument for
156 translations that only remove characters without re-mapping the
157 remaining characters.
158
Georg Brandl5cb76c12007-03-21 09:00:39 +0000159- Patch #1682205: a TypeError while unpacking an iterable is no longer
160 masked by a generic one with the message "unpack non-sequence".
161
Neal Norwitzaa754b72007-03-21 06:39:48 +0000162- Remove unused file Python/fmod.c.
163
Guido van Rossum143b5642007-03-23 04:58:42 +0000164- Bug #1683368: The object.__init__() and object.__new__() methods are
165 now stricter in rejecting excess arguments. The only time when
166 either allows excess arguments is when it is not overridden and the
167 other one is. For backwards compatibility, when both are
168 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +0000169 warning later). Also, type.__init__() insists on the same signature
170 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +0000171
Georg Brandl2b869942007-03-17 16:08:45 +0000172- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
173 to complex using its __complex__() method before falling back to the
174 __float__() method. Therefore, the functions in the cmath module now
175 can operate on objects that define a __complex__() method.
176
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +0000177- Patch #1623563: allow __class__ assignment for classes with __slots__.
178 The old and the new class are still required to have the same slot names.
179
Collin Winter77c67bd2007-03-16 04:11:30 +0000180- Patch #1642547: Fix an error/crash when encountering syntax errors in
181 complex if statements.
182
Žiga Seilnacht20f43d32007-03-15 11:44:55 +0000183- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
184 is called with an object that is faking its type.
185
Žiga Seilnacht71436f02007-03-14 12:24:09 +0000186- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
187 name.
188
Georg Brandl5240d742007-03-13 20:46:32 +0000189- Patch #1444529: the builtin compile() now accepts keyword arguments.
190
Georg Brandl7b9c5552007-03-12 14:30:05 +0000191- Bug #1678647: write a newline after printing an exception in any
192 case, even when converting the value to a string failed.
193
Georg Brandl871f1bc2007-03-12 13:17:36 +0000194- The dir() function has been extended to call the __dir__() method on
195 its argument, if it exists. If not, it will work like before. This allows
196 customizing the output of dir() in the presence of a __getattr__().
197
Collin Winter276887b2007-03-12 16:11:39 +0000198- Patch #922167: Python no longer segfaults when faced with infinitely
199 self-recursive reload() calls (as reported by bug #742342).
200
Žiga Seilnacht89032082007-03-11 15:54:54 +0000201- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
202
Collin Wintere38051d2007-03-09 20:33:07 +0000203- Patch #1491866: change the complex() constructor to allow parthensized
204 forms. This means complex(repr(x)) now works instead of raising a
205 ValueError.
206
Georg Brandlaa2321b2007-03-07 00:40:28 +0000207- Patch #703779: unset __file__ in __main__ after running a file. This
208 makes the filenames the warning module prints much more sensible when
209 a PYTHONSTARTUP file is used.
210
Georg Brandl49aafc92007-03-07 00:34:46 +0000211- Variant of patch #697613: don't exit the interpreter on a SystemExit
212 exception if the -i command line option or PYTHONINSPECT environment
213 variable is given, but break into the interactive interpreter just like
214 on other exceptions or normal program exit.
215
Georg Brandl00cd8182007-03-06 18:41:12 +0000216- Patch #1638879: don't accept strings with embedded NUL bytes in long().
217
Georg Brandl098cd692007-03-06 12:17:50 +0000218- Bug #1674503: close the file opened by execfile() in an error condition.
219
Georg Brandl0fca97a2007-03-05 22:28:08 +0000220- Patch #1674228: when assigning a slice (old-style), check for the
221 sq_ass_slice instead of the sq_slice slot.
222
Neal Norwitz88516a62007-02-26 22:41:45 +0000223- When printing an unraisable error, don't print exceptions. before the name.
224 This duplicates the behavior whening normally printing exceptions.
225
Martin v. Löwisfd963262007-02-09 12:19:32 +0000226- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
227
Brett Cannon129bd522007-01-30 21:34:36 +0000228- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
229 catch a string exception raises DeprecationWarning.
230
Brett Cannonf5bee302007-01-23 23:21:22 +0000231- Bug #1377858: Fix the segfaulting of the interpreter when an object created
232 a weakref on itself during a __del__ call for new-style classes (classic
233 classes still have the bug).
234
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000235- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
236 frame's thread state.
237
Thomas Wouters6ed19652007-01-23 13:50:49 +0000238- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
239
Martin v. Löwis4885e7d2007-01-19 06:42:22 +0000240- Bug #1637022: Prefix AST symbols with _Py_.
241
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000242- Prevent seg fault on shutdown which could occur if an object
243 raised a warning.
244
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000245- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
246 to avoid relying on atexit.
247
Raymond Hettinger94547f72006-12-20 06:42:06 +0000248- Bug #1590891: random.randrange don't return correct value for big number
249
Georg Brandl283a1352006-11-19 08:48:30 +0000250- Patch #1586791: Better exception messages for some operations on strings,
251 tuples and lists.
252

258
Georg Brandlb9f4ad32006-10-29 18:31:42 +0000259- Bug #1576657: when setting a KeyError for a tuple key, make sure that
260 the tuple isn't used as the "exception arguments tuple".
261
Neal Norwitz21997af2006-10-28 21:19:07 +0000262- Bug #1565514, SystemError not raised on too many nested blocks.
263
Thomas Hellerdf08f0b2006-10-27 18:31:36 +0000264- Bug #1576174: WindowsError now displays the windows error code
265 again, no longer the posix error code.
266
Martin v. Löwisb5bc5372006-10-27 06:16:31 +0000267- Patch #1549049: Support long values in structmember, issue warnings
268 if the assigned value for structmember fields gets truncated.
269
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000270- Update the peephole optimizer to remove more dead code (jumps after returns)
271 and inline unconditional jumps to returns.
272
Georg Brandl2c1375c2006-10-12 11:27:59 +0000273- Bug #1545497: when given an explicit base, int() did ignore NULs
274 embedded in the string to convert.
275
Georg Brandl846f73a2006-10-08 07:11:54 +0000276- Bug #1569998: break inside a try statement (outside a loop) is now
277 recognized and rejected.
278
Armin Rigo7ccbca92006-10-04 12:17:45 +0000279- list.pop(x) accepts any object x following the __index__ protocol.
280
281- Fix some leftovers from the conversion from int to Py_ssize_t
282 (relevant to strings and sequences of more than 2**31 items).
283
284- A number of places, including integer negation and absolute value,
285 were fixed to not rely on undefined behaviour of the C compiler
286 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +0000287
Georg Brandl3267d282006-09-30 09:03:42 +0000288- Bug #1566800: make sure that EnvironmentError can be called with any
289 number of arguments, as was the case in Python 2.4.
290
Georg Brandl5d59c092006-09-30 08:43:30 +0000291- Patch #1567691: super() and new.instancemethod() now don't accept
292 keyword arguments any more (previously they accepted them, but didn't
293 use them).
294
Georg Brandla10d3af2006-09-24 12:35:36 +0000295- Fix a bug in the parser's future statement handling that led to "with"
296 not being recognized as a keyword after, e.g., this statement:
297 from __future__ import division, with_statement
298

Collin Winterfaaa2042007-03-10 03:35:34 +0000608 be equal to calling getsockname() on the server's socket. Fixed by

934 time so that opening a database previously created with the DB_DUP or
935 DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
936 Specifically: dictionary assignment to a DB object will replace all
937 values for a given key when the database allows duplicate values.
938 DB users should use DB.put(k, v) when they want to store duplicates; not
939 DB[k] = v.
940

1237
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001238- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001239 compared equal or unequal to a string and a UnicodeDecodeError
1240 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001241
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001242 Instead, the equal (==) and unequal (!=) comparison operators will
1243 now issue a UnicodeWarning and interpret the two objects as
1244 unequal. The UnicodeWarning can be filtered as desired using
1245 the warning framework, e.g. silenced completely, turned into an
1246 exception, logged, etc.
1247
1248 Note that compare operators other than equal and unequal will still
1249 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001250
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001251- Fix segfault when doing string formatting on subclasses of long.
1252
1253- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1254 with new-style classes.
1255
1256- Fix bug related to __len__ functions returning negative values with
1257 classic classes.
1258
1259- Patch #1538606, Fix __index__() clipping. There were some problems
1260 discovered with the API and how integers that didn't fit into Py_ssize_t
1261 were handled. This patch attempts to provide enough alternatives
1262 to effectively use __index__.
1263
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001264- Bug #1536021: __hash__ may now return long int; the final hash
1265 value is obtained by invoking hash on the long int.
1266
Thomas Hellerab1049c2006-08-08 17:37:00 +00001267- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1268
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001269- Bug #1535165: fixed a segfault in input() and raw_input() when
1270 sys.stdin is closed.
1271
Thomas Heller74d36f02006-08-04 18:17:40 +00001272- On Windows, the PyErr_Warn function is now exported from
1273 the Python dll again.
1274
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001275- Bug #1191458: tracing over for loops now produces a line event
1276 on each iteration. Fixing this problem required changing the .pyc
1277 magic number. This means that .pyc files generated before 2.5c1
1278 will be regenerated.
1279
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001280- Bug #1333982: string/number constants were inappropriately stored
1281 in the byte code and co_consts even if they were not used, ie
1282 immediately popped off the stack.
1283
Georg Brandle9462c72006-08-04 18:03:37 +00001284- Fixed a reference-counting problem in property().

1287Library
1288-------
1289
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001290- Fix a bug in the ``compiler`` package that caused invalid code to be
1291 generated for generator expressions.
1292
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001293- The distutils version has been changed to 2.5.0. The change to
1294 keep it programmatically in sync with the Python version running
1295 the code (introduced in 2.5b3) has been reverted. It will continue
1296 to be maintained manually as static string literal.
1297
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001298- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001299 and this cannot be converted to the required C type, an exception is
1300 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001301 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001302
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001303- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001304 an exception.
1305
Tim Petersc10c9d02006-09-05 02:18:09 +00001306- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001307 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001308 workarounds for clocks with low resolution, to stop the code yielding
1309 duplicate UUIDs.
1310
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001311- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1312 before raising SystemExit, allowing IDLE to honor quit() and exit().
1313
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001314- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1315
Georg Brandl7a1af772006-08-14 21:55:28 +00001316- Patch #1536071: trace.py should now find the full module name of a
1317 file correctly even on Windows.
1318
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001319- logging's atexit hook now runs even if the rest of the module has
1320 already been cleaned up.
1321
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001322- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001323
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001324- Bug #1531405, format_exception no longer raises an exception if
1325 str(exception) raised an exception.
1326
Neil Schemenauer06ded092006-08-04 16:20:30 +00001327- Fix a bug in the ``compiler`` package that caused invalid code to be
1328 generated for nested functions.

Georg Brandl3335a7a2006-08-14 21:42:55 +00001336- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1337 raises the correct exceptions.
1338
Thomas Heller1ce433e2006-08-14 16:20:04 +00001339- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1340 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1341
Thomas Heller86720042006-08-14 11:17:48 +00001342- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1343 uses the _as_parameter_ attribute when objects are passed to foreign
1344 function calls. The ctypes version number was changed to 1.0.1.
1345
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001346- Bug #1530559, struct.pack raises TypeError where it used to convert.
1347 Passing float arguments to struct.pack when integers are expected
1348 now triggers a DeprecationWarning.
1349

1399-----------------
1400
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001401- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001402 returned a long (see PEP 353).
1403
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001404- Bug #1515471: string.replace() accepts character buffers again.
1405
Neal Norwitz07aadb12006-07-30 06:55:48 +00001406- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1407 This provides the proper warning for struct.pack().
1408 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1409
Neal Norwitz0d62a062006-07-30 06:53:31 +00001410- Patch #1531113: Fix augmented assignment with yield expressions.
1411 Also fix a SystemError when trying to assign to yield expressions.
1412
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001413- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1414 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1415 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1416 excessive filesystem operations during imports.
1417
Tim Petersbc24eee2006-07-27 01:14:53 +00001418- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1419 operations on signed longs that are formally undefined by C.
1420 Unfortunately, at least one compiler now cares about that, so complicated
1421 the code to make that compiler happy again.
1422
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001423- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1424
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001425- Patch #1232023: Stop including current directory in search
1426 path on Windows.
1427
Neal Norwitze1fdb322006-07-21 05:32:28 +00001428- Fix some potential crashes found with failmalloc.
1429
Neal Norwitze7563102006-07-17 01:00:16 +00001430- Fix warnings reported by Klocwork's static analysis tool.

1433 had more than 255 blank lines.
1434
Georg Brandl9dceedb2006-07-12 15:31:17 +00001435- Patch #1521179: Python now accepts the standard options ``--help`` and
1436 ``--version`` as well as ``/?`` on Windows.
1437
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001438- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001439 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001440 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001441
Tim Peters112aad32006-07-19 00:03:19 +00001442- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001443 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001444 new ``sys._current_frames()`` returns a dictionary with one entry,

1451-------
1452
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001453- Correction of patch #1455898: In the mbcs decoder, set final=False
1454 for stream decoder, but final=True for the decode function.
1455
Georg Brandl07fec3a2006-08-01 18:49:24 +00001456- os.urandom no longer masks unrelated exceptions like SystemExit or
1457 KeyboardInterrupt.
1458
Tim Peters4643c2f2006-08-10 22:45:34 +00001459- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001460 shutil.copytree on Windows
1461
Georg Brandle34ac7c2006-07-30 11:07:23 +00001462- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1463 refers to file descriptors, not file objects.
1464
Tim Petersc10c9d02006-09-05 02:18:09 +00001465- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001466 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001467 #1513611, and probably others.
1468
Georg Brandledd9b0d2006-07-29 09:33:26 +00001469- Bug #1441397: The compiler module now recognizes module and function
1470 docstrings correctly as it did in Python 2.4.
1471
Tim Peters6f681472006-07-27 23:44:37 +00001472- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1473 lost that tests are sorted by name before being run. This rarely
1474 matters for well-written tests, but can create baffling symptoms if
1475 side effects from one test to the next affect outcomes. ``DocTestFinder``
1476 has been changed to sort the list of tests it returns.
1477
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001478- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001479 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001480
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001481- Bug #978833: Really close underlying socket in _socketobject.close.
1482
Georg Brandl8c036cc2006-08-20 13:15:39 +00001483- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1484 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001485
Georg Brandlcf0c1722006-07-26 07:23:32 +00001486- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1487 to recursive calls and call it with the failing package name.
1488
Martin v. Löwis0b483032006-07-25 09:53:12 +00001489- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1490
Georg Brandlc13c34c2006-07-24 14:09:56 +00001491- Patch #1515343: Fix printing of deprecated string exceptions with a
1492 value in the traceback module.
1493
Greg Ward48fae7a2006-07-23 16:05:51 +00001494- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1495
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001496- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1497
Brett Cannoncaebe222006-07-18 04:41:36 +00001498- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1499 argument tuple. For arguments where zero is illegal, the value is forced to
1500 the minimum value that is correct. This is to support an undocumented but
1501 common way people used to fill in inconsequential information in the time
1502 tuple pre-2.4.
1503
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001504- Patch #1220874: Update the binhex module for Mach-O.
1505
Barry Warsawb110bad2006-07-21 14:51:07 +00001506- The email package has improved RFC 2231 support, specifically for
1507 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1508 (name*0=<blah>) parameter continuations. This may change the types of
1509 values returned from email.message.Message.get_param() and friends.
1510 Specifically in some cases where non-encoded continuations were used,
1511 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1512 will just return the string (since non-encoded continuations don't have
1513 charset and language parts).
1514
1515 Also, whereas % values were decoded in all parameter continuations, they are
1516 now only decoded in encoded parameter parts.
1517
Ronald Oussoren3075e162006-07-25 20:28:55 +00001518- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1519
1520- Bug #1517996: IDLE now longer shows the default Tk menu when a
1521 path browser, class browser or debugger is the frontmost window on MacOS X
1522
Barry Warsaw00decd72006-07-27 23:43:15 +00001523- Patch #1520294: Support for getset and member descriptors in types.py,
1524 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1525 of an object against these built-in types and more importantly, for getting
1526 their docstrings printed in the interactive interpreter's help() function.

1530-----------------
1531
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001532- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1533 a socket operation on a socket with a timeout, the exception will be
1534 caught correctly. Previously, the exception was not caught.
1535
Thomas Heller1393d6a2006-07-28 21:43:20 +00001536- Patch #1529514: The _ctypes extension is now compiled on more
1537 openbsd target platforms.
1538
Tim Peters9cab5932006-07-28 00:30:00 +00001539- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1540 a memory leak, affecting pickles and deep copies.
1541
Tim Petersbc24eee2006-07-27 01:14:53 +00001542- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001543 Paul Eggert.
1544
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001545- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1546
Thomas Hellerce049a02006-07-14 17:51:14 +00001547- Patch #1521817: Index range checking on ctypes arrays containing
1548 exactly one element enabled again. This allows iterating over these
1549 arrays, without the need to check the array size before.
1550
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001551- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001552 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001553 /dev/null in certain cases; this is now fixed.
1554
Thomas Heller47d7a062006-07-12 08:43:47 +00001555- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1556 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001557
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001558- Because of a misspelled preprocessor symbol, ctypes was always
1559 compiled without thread support; this is now fixed.
1560
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001561- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1562 methods now allow their database parameter to be None as the
1563 sleepycat API allows.
1564
Matt Flemingec926502006-07-28 11:27:27 +00001565- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1566 bluetooth API compared with Linux and FreeBSD.
1567
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001568Tests
1569-----
1570
1571- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1572 how long the test file should take to play. Now accepts taking 2.93 secs
1573 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1574
Georg Brandl4793aa32006-07-28 18:31:39 +00001575- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1576 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1577 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001584Mac
1585---
1586
1587- PythonLauncher now works correctly when the path to the script contains
1588 characters that are treated specially by the shell (such as quotes).
1589
1590- Bug #1527397: PythonLauncher now launches scripts with the working directory
1591 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001592 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001593 expect.

1602-----------------
1603
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001604- Bug #1441486: The literal representation of -(sys.maxint - 1)
1605 again evaluates to a int object, not a long.
1606
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001607- Bug #1501934: The scope of global variables that are locally assigned
1608 using augmented assignment is now correctly determined.
1609
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001610- Bug #927248: Recursive method-wrapper objects can now safely
1611 be released.
1612
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001613- Bug #1417699: Reject locale-specific decimal point in float()
1614 and atof().
1615
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001616- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1617 omit a default "error" argument for NULL pointer. This allows
1618 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001619
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001620- Bug #1519018: 'as' is now validated properly in import statements.
1621
Neal Norwitz28746ab2006-07-09 22:14:42 +00001622- On 64 bit systems, int literals that use less than 64 bits are
1623 now ints rather than longs.
1624
Neal Norwitzed657552006-07-10 00:04:44 +00001625- Bug #1512814, Fix incorrect lineno's when code at module scope
1626 started after line 256.
1627
Tim Peters32a83612006-07-10 21:08:24 +00001628- New function ``sys._current_frames()`` returns a dict mapping thread
1629 id to topmost thread stack frame. This is for expert use, and is
1630 especially useful for debugging application deadlocks. The functionality
1631 was previously available in Fazal Majid's ``threadframe`` extension
1632 module, but it wasn't possible to do this in a wholly threadsafe way from
1633 an extension.

1639 VS 2003.
1640
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001641- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1642
Tim Peters32a83612006-07-10 21:08:24 +00001643- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001644 environment variable to be set in order to the SDK environment
1645 for finding the compiler, include files, etc.

1650
Thomas Woutersadd19112006-07-05 11:03:49 +00001651- string.Template() now correctly handles tuple-values. Previously,
1652 multi-value tuples would raise an exception and single-value tuples would
1653 be treated as the value they contain, instead.
1654
Martin v. Löwisede77f52006-07-03 13:01:35 +00001655- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1657
Martin v. Löwis45482392006-07-03 12:28:58 +00001658- Bug #1267547: Put proper recursive setup.py call into the
1659 spec file generated by bdist_rpm.
1660
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001661- Bug #1514693: Update turtle's heading when switching between
1662 degrees and radians.
1663
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001664- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001665 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001666
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001667- Bug #1514703: Only setup canvas window in turtle when the canvas
1668 is created.
1669
Martin v. Löwis7596e832006-07-01 15:33:37 +00001670- Bug #1513223: .close() of a _socketobj now releases the underlying
1671 socket again, which then gets closed as it becomes unreferenced.
1672
Fred Drake10497c82006-06-29 02:57:48 +00001673- Bug #1504333: Make sgmllib support angle brackets in quoted
1674 attribute values.
1675
1676- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1677 sgmllib ('[' and ']' were not accepted).
1678
Georg Brandl1be63af2006-06-28 20:23:25 +00001679- Fix a bug in the turtle module's end_fill function.
1680
Brett Cannon53ab5b72006-06-22 16:49:14 +00001681- Bug #1510580: The 'warnings' module improperly required that a Warning
1682 category be either a types.ClassType and a subclass of Warning. The proper
1683 check is just that it is a subclass with Warning as the documentation states.
1684
Georg Brandlad29e632006-06-21 17:45:17 +00001685- The compiler module now correctly compiles the new try-except-finally
1686 statement (bug #1509132).
1687
Neal Norwitz60373cd2006-06-22 06:30:50 +00001688- The wsgiref package is now installed properly on Unix.
1689
Vinay Sajip28e57612006-07-01 10:45:20 +00001690- A bug was fixed in logging.config.fileConfig() which caused a crash on
1691 shutdown when fileConfig() was called multiple times.
1692
Gerhard Häring762fbd32006-07-02 17:48:30 +00001693- The sqlite3 module did cut off data from the SQLite database at the first
1694 null character before sending it to a custom converter. This has been fixed
1695 now.

1698-----------------
1699
Tim Peters112aad32006-07-19 00:03:19 +00001700- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1701 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1702 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001703
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001704- Assigning None to pointer type fields in ctypes structures possible
1705 overwrote the wrong fields, this is fixed now.
1706
1707- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1708 on non-Windows platforms.
1709
1710- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1711 integer or long, without range checking.
1712
1713- Patch #1517790: It is now possible to use custom objects in the ctypes
1714 foreign function argtypes sequence as long as they provide a from_param
1715 method, no longer is it required that the object is a ctypes type.
1716
1717- The '_ctypes' extension module now works when Python is configured
1718 with the --without-threads option.
1719
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001720- Bug #1513646: os.access on Windows now correctly determines write
1721 access, again.
1722
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001723- Bug #1512695: cPickle.loads could crash if it was interrupted with
1724 a KeyboardInterrupt.
1725
Neal Norwitza12aa882006-07-06 06:45:08 +00001726- Bug #1296433: parsing XML with a non-default encoding and
1727 a CharacterDataHandler could crash the interpreter in pyexpat.
1728
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001729- Patch #1516912: improve Modules support for OpenVMS.

1735
Tim Peters32a83612006-07-10 21:08:24 +00001736- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001737 Previously, the slight difference could cause compilation errors of the

Anthony Baxter51bcb682006-04-05 14:51:42 +00001770
1771Core and builtins
1772-----------------
1773
Georg Brandla56b9152006-06-19 06:35:54 +00001774- Patch #1507676: Error messages returned by invalid abstract object operations
1775 (such as iterating over an integer) have been improved and now include the
1776 type of the offending object to help with debugging.
1777
Brett Cannonea3912b2006-06-13 21:46:41 +00001778- Bug #992017: A classic class that defined a __coerce__() method that returned
1779 its arguments swapped would infinitely recurse and segfault the interpreter.
1780
Neal Norwitz909eb122006-06-12 02:13:21 +00001781- Fix the socket tests so they can be run concurrently.
1782
Neal Norwitzb9845e72006-06-12 02:11:18 +00001783- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001784 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001785
Brett Cannon22565aa2006-06-09 22:31:23 +00001786- Bug #532646: object.__call__() will continue looking for the __call__
1787 attribute on objects until one without one is found. This leads to recursion
1788 when you take a class and set its __call__ attribute to an instance of the
1789 class. Originally fixed for classic classes, but this fix is for new-style.
1790 Removes the infinite_rec_3 crasher.
1791
Georg Brandl24250812006-06-09 18:45:48 +00001792- The string and unicode methods startswith() and endswith() now accept
1793 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1794
Brett Cannonde3b0522006-06-08 17:00:45 +00001795- Buffer objects, at the C level, never used the char buffer
1796 implementation even when the char buffer for the wrapped object was
1797 explicitly requested (originally returned the read or write buffer).
1798 Now a TypeError is raised if the char buffer is not present but is
1799 requested.
1800
Georg Brandlddbaa662006-06-04 21:56:52 +00001801- Patch #1346214: Statements like "if 0: suite" are now again optimized
1802 away like they were in Python 2.4.
1803
Georg Brandlb7c8f542006-05-27 12:30:25 +00001804- Builtin exceptions are now full-blown new-style classes instead of
1805 instances pretending to be classes, which speeds up exception handling
1806 by about 80% in comparison to 2.5a2.
1807
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001808- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1809 Unicode 4.1.
1810
Georg Brandlf4ef1162006-05-26 18:03:31 +00001811- Patch #921466: sys.path_importer_cache is now used to cache valid and
1812 invalid file paths for the built-in import machinery which leads to
1813 fewer open calls on startup.
1814
Tim Peters696cf432006-05-24 21:10:40 +00001815- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1816 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1817 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1818 the number of input digits (it was and remains linear-time for bases
1819 2, 4, 8, 16 and 32).
1820
Tim Petersb713ec22006-05-23 18:45:30 +00001821- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1822 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1823 an integer close to ``sys.maxint``. This was repaired by patch
1824 #1335972, which also gives a nice speedup.
1825
Richard Jonescebbefc2006-05-23 18:28:17 +00001826- Patch #1337051: reduced size of frame objects.
1827
1828- PyErr_NewException now accepts a tuple of base classes as its
1829 "base" parameter.
1830
Richard Jones7c88dcc2006-05-23 10:37:38 +00001831- Patch #876206: function call speedup by retaining allocated frame
1832 objects.
1833
Georg Brandl7b90e162006-05-18 07:01:27 +00001834- Bug #1462152: file() now checks more thoroughly for invalid mode
1835 strings and removes a possible "U" before passing the mode to the
1836 C library function.
1837
Neal Norwitz1004a532006-05-15 07:17:23 +00001838- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1839
Neal Norwitz373f0a72006-05-15 07:04:36 +00001840- Bug #1487966: Fix SystemError with conditional expression in assignment
1841
Martin v. Löwis879768d2006-05-11 13:28:43 +00001842- WindowsError now has two error code attributes: errno, which carries
1843 the error values from errno.h, and winerror, which carries the error
1844 values from winerror.h. Previous versions put the winerror.h values
1845 (from GetLastError()) into the errno attribute.
1846
Martin v. Löwis77736712006-05-04 05:51:03 +00001847- Patch #1475845: Raise IndentationError for unexpected indent.
1848
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001849- Patch #1479181: split open() and file() from being aliases for each other.
1850
Tim Peters44bd9862006-06-01 13:49:23 +00001851- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1852 methods were always silently ignored by dictionaries when comparing keys.
1853 They are now passed through (except when using the C API function
1854 ``PyDict_GetItem()``, whose semantics did not change).
1855
1856- Bug #1456209: In some obscure cases it was possible for a class with a
1857 custom ``__eq__()`` method to confuse dict internals when class instances
1858 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1859 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001861Extension Modules
1862-----------------
1863
Trent Mick960a3f82006-06-28 20:30:41 +00001864- Bug #1295808: expat symbols should be namespaced in pyexpat
1865
1866- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1867
Brett Cannon6ee7d012006-06-08 16:23:04 +00001868- Change binascii.hexlify to accept a read-only buffer instead of only a char
1869 buffer and actually follow its documentation.
1870
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001871- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1872
Nick Coghlanc649ec52006-05-29 12:43:05 +00001873- Patch #1478788 (modified version): The functional extension module has
1874 been renamed to _functools and a functools Python wrapper module added.
1875 This provides a home for additional function related utilities that are
1876 not specifically about functional programming. See PEP 309.
1877
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001878- Patch #1493701: performance enhancements for struct module.
1879

1881
Georg Brandl8d3342b2006-05-16 07:38:27 +00001882- Patch #1435422: zlib's compress and decompress objects now have a
1883 copy() method.
1884
Andrew MacIntyre92913322006-06-13 15:04:24 +00001885- Patch #1454481: thread stack size is now tunable at runtime for thread
1886 enabled builds on Windows and systems with Posix threads support.
1887
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001888- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1889 (up to the system limit of 32K characters).
1890
1891- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1892 As a result, these functions now raise WindowsError instead of OSError.
1893
Tim Peters7a822da2006-05-25 21:50:17 +00001894- ``time.clock()`` on Win64 should use the high-performance Windows
1895 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1896 Windows platforms).
1897
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001898- Calling Tk_Init twice is refused if the first call failed as that
1899 may deadlock.
1900
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001901- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1902 accept it without potentially using an uninitialized pointer.
1903
1904- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1905 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1906 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001907
Gregory P. Smith372b5832006-06-05 18:48:21 +00001908- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001909 [pybsddb project SF patch number 1466734]
1910
Gregory P. Smith372b5832006-06-05 18:48:21 +00001911- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1912 parameter is supplied. [SF pybsddb bug #1477863]
1913
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001914- bsddb: the __len__ method of a DB object has been fixed to return correct
1915 results. It could previously incorrectly return 0 in some cases.
1916 Fixes SF bug 1493322 (pybsddb bug 1184012).
1917
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001918- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1919 aborts the db transaction safely when a modifier callback fails.
1920 Fixes SF python patch/bug #1408584.
1921
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001922- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001923 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001924 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1925 database calls that would previously deadlock. [SF python bug #775414]
1926
Vinay Sajip28e57612006-07-01 10:45:20 +00001927- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1933-------
1934
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001935- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1936 functions.
1937
Martin v. Löwis3798da02006-06-17 18:44:27 +00001938- Patch #812986: Update turtle output even if not tracing.
1939
Vinay Sajip28e57612006-07-01 10:45:20 +00001940- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001941 Tkinter.BaseWidget.
1942
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001943- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1944
Martin v. Löwis337487e2006-06-17 09:15:14 +00001945- Patch #763580: Add name and value arguments to Tkinter variable
1946 classes.
1947
Georg Brandl83cc0d02006-06-14 08:50:03 +00001948- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1949 mime.types file for determining MIME types.
1950
Georg Brandl2605ca82006-06-14 06:08:31 +00001951- Bug #1339007: Shelf objects now don't raise an exception in their
1952 __del__ method when initialization failed.
1953
Martin v. Löwisd8251432006-06-14 05:21:04 +00001954- Patch #1455898: The MBCS codec now supports the incremental mode for
1955 double-byte encodings.
1956
Tim Peters43898b42006-06-14 04:09:25 +00001957- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1958 guarantee that adjacent triples in the return list always describe
1959 non-adjacent blocks. Previously, a pair of matching blocks could end
1960 up being described by multiple adjacent triples that formed a partition
1961 of the matching pair.
1962
Greg Ward0e0c9f42006-06-11 16:24:11 +00001963- Bug #1498146: fix optparse to handle Unicode strings in option help,
1964 description, and epilog.
1965
Greg Wardd1c797e2006-06-11 14:42:41 +00001966- Bug #1366250: minor optparse documentation error.
1967
Greg Ward7f547402006-06-11 00:40:49 +00001968- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1969 clarify docs.
1970
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001971- The wsgiref package has been added to the standard library.
1972
Nick Coghlan676725d2006-06-08 13:54:49 +00001973- The functions update_wrapper() and wraps() have been added to the functools
1974 module. These make it easier to copy relevant metadata from the original
1975 function when writing wrapper functions.
1976
Tim Petersd6a9eef2006-06-05 01:48:21 +00001977- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1978 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001979
Martin v. Löwis3f767792006-06-04 19:36:28 +00001980- Patch #1359618: Speed up charmap encoder by using a trie structure
1981 for lookup.
1982
Tim Petersd609b1a2006-06-02 23:22:51 +00001983- The functions in the ``pprint`` module now sort dictionaries by key
1984 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1985 if and only if its display required more than one line, although that
1986 wasn't documented. The new behavior increases predictability; e.g.,
1987 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1988
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001989- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1990 (thanks for J. J. Lee).
1991
Georg Brandl2b330372006-05-28 20:23:12 +00001992- Patch #1496206: improve urllib2 handling of passwords with respect to
1993 default HTTP and HTTPS ports.
1994
George Yoshidaf3c65de2006-05-28 16:39:09 +00001995- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1996
Bob Ippolito7298f272006-05-23 18:43:47 +00001997- Patch #1281707: speed up gzip.readline.
1998
Georg Brandlb89316f2006-05-17 15:51:16 +00001999- Patch #1180296: Two new functions were added to the locale module:
2000 format_string() to get the effect of "format % items" but locale-aware,
2001 and currency() to format a monetary number with currency sign.
2002
Georg Brandle3a25832006-05-17 14:56:04 +00002003- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2004 and several features added, such as speed and geometry control.
2005
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002006- Patch #1488881: add support for external file objects in bz2 compressed
2007 tarfiles.
2008
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002009- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2010 stdout arguments, making it possible to redirect input and output
2011 for remote debugging.
2012
2013- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2014 a couple of issues, notably handling of long file names using the
2015 GNU LONGNAME extension.
2016
2017- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2018 new flag when ``name`` is already the name of an option flag.
2019
2020- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2021 package.
2022
2023- Patch #1472854: make the rlcompleter.Completer class usable on non-
2024 UNIX platforms.
2025
2026- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
2027
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00002028- Bug #1472827: correctly escape newlines and tabs in attribute values in

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002059What's New in Python 2.5 alpha 2?
2060=================================
2061
2062*Release date: 27-APR-2006*
2063
2064Core and builtins
2065-----------------
2066
Thomas Heller1b046642006-04-18 18:51:06 +00002067- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2068 by converting these apis from macros into exported functions again:
2069
2070 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2071 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2072 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2073 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2074 PyRun_String Py_CompileString
2075
Martin v. Löwis45294a92006-04-18 06:24:08 +00002076- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2077
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002078- All uses of PyStructSequence_InitType have been changed to initialize
2079 the type objects only once, even if the interpreter is initialized
2080 multiple times.
2081
Neal Norwitz61546162006-04-14 05:20:28 +00002082- Bug #1454485, array.array('u') could crash the interpreter. This was
2083 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2084 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2085
2086- Py_UNICODE is unsigned. It was always documented as unsigned, but
2087 due to a bug had a signed value in previous versions.
2088
Tim Peters3a5e8b12006-04-11 01:44:07 +00002089- Patch #837242: ``id()`` of any Python object always gives a positive
2090 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2091 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002092 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002093 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002094
Tim Peters3a5e8b12006-04-11 01:44:07 +00002095 def __hash__(self):
2096 return id(self) # WRONG
2097
2098 because a hash result must be a (short) Python int but it was always
2099 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002100 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002101 was always usable as a hash value before this patch. That's no longer
2102 necessarily so.
2103
2104- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002105 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002106 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002107 #1454844)
2108
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002109- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2110 involving generators that have paused outside of any ``try`` or ``with``
2111 blocks. (In 2.5a1, a paused generator that was part of a reference
2112 cycle could not be garbage collected, regardless of whether it was
2113 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00002114
Anthony Baxter51bcb682006-04-05 14:51:42 +00002115Extension Modules
2116-----------------
2117
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00002118- Patch #1191065: Fix preprocessor problems on systems where recvfrom
2119 is a macro.
2120
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002121- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2122 fails with an error condition.
2123
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002124- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2125
2126- Bug #1117761: bsddb.*open() no longer raises an exception when using
2127 the cachesize parameter.
2128
2129- Bug #1149413: bsddb.*open() no longer raises an exception when using
2130 a temporary db (file=None) with the 'n' flag to truncate on open.
2131
2132- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2133 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002134
Armin Rigoa9017c32006-04-19 11:50:27 +00002135- Patch #1062014: AF_UNIX sockets under Linux have a special
2136 abstract namespace that is now fully supported.
2137
Anthony Baxter51bcb682006-04-05 14:51:42 +00002138Library
2139-------
2140
Peter Astrand7d1d4362006-07-14 14:04:45 +00002141- Bug #1223937: subprocess.CalledProcessError reports the exit status
2142 of the process using the returncode attribute, instead of
2143 abusing errno.
2144
Tim Peters711bf302006-04-25 03:31:36 +00002145- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2146 a doctest to be skipped (the code is not run, and the expected output
2147 or exception is ignored).
2148
Nick Coghlanda2268f2006-04-24 04:37:15 +00002149- Fixed contextlib.nested to cope with exceptions being raised and
2150 caught inside exit handlers.
2151
Greg Wardab05edc2006-04-23 03:47:58 +00002152- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2153 hex, octal, or binary; add ``append_const`` action; keep going if
2154 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2155 added ``epilog`` for better help generation).
2156
Tim Peters21fbd572006-04-21 21:18:10 +00002157- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2158 called from a thread spawned as a side effect of importing a module.
2159
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002160- The pydoc module now supports documenting packages contained in
2161 .zip or .egg files.
2162
2163- The pkgutil module now has several new utility functions, such
2164 as ``walk_packages()`` to support working with packages that are either
2165 in the filesystem or zip files.
2166
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002167- The mailbox module can now modify and delete messages from
2168 mailboxes, in addition to simply reading them. Thanks to Gregory
2169 K. Johnson for writing the code, and to the 2005 Google Summer of
2170 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002171
Tim Petersc7605f22006-04-17 21:12:33 +00002172- The ``__del__`` method of class ``local`` in module ``_threading_local``
2173 returned before accomplishing any of its intended cleanup.
2174
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002175- Patch #790710: Add breakpoint command lists in pdb.
2176
Martin v. Löwis0db2a982006-04-16 20:55:38 +00002177- Patch #1063914: Add Tkinter.Misc.clipboard_get().
2178
Martin v. Löwis4b501e62006-04-15 08:41:11 +00002179- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
2180
Anthony Baxtere29002c2006-04-12 12:07:31 +00002181- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2182 Windows. Bug #1469163.
2183
Phillip J. Eby47032112006-04-11 01:07:43 +00002184- The warnings, linecache, inspect, traceback, site, and doctest modules
2185 were updated to work correctly with modules imported from zipfiles or
2186 via other PEP 302 __loader__ objects.
2187
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002188- Patch #1467770: Reduce usage of subprocess._active to processes which
2189 the application hasn't waited on.
2190
Martin v. Löwisb04dee92006-04-10 08:34:21 +00002191- Patch #1462222: Fix Tix.Grid.
2192
Neal Norwitza31bf182006-04-09 03:35:43 +00002193- Fix exception when doing glob.glob('anything*/')
2194
Skip Montanaro262fb922006-04-21 02:31:07 +00002195- The pstats.Stats class accepts an optional stream keyword argument to
2196 direct output to an alternate file-like object.
2197
Anthony Baxter51bcb682006-04-05 14:51:42 +00002198Build
2199-----
2200
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002201- The Makefile now has a reindent target, which runs reindent.py on
2202 the library.
2203
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002204- Patch #1470875: Building Python with MS Free Compiler
2205
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002206- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002207
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002208- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2209 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002210 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002211 CXX from --with-cxx-main, see description in README.
2212
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002213- Patch #1429775: Link extension modules with the shared libpython.
2214
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002215- Fixed a libffi build problem on MIPS systems.
2216
Tim Peters8931ff12006-05-13 23:28:20 +00002217- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2218 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2219 and "%zu" for unsigned integers of type ``size_t``.
2220
Anthony Baxter51bcb682006-04-05 14:51:42 +00002221Tests
2222-----
2223
Nick Coghlanda2268f2006-04-24 04:37:15 +00002224- test_contextlib now checks contextlib.nested can cope with exceptions
2225 being raised and caught inside exit handlers.
2226
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002227- test_cmd_line now checks operation of the -m and -c command switches
2228
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002229- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2230 it separately and by hand. It also wasn't cleaning up its changes to
2231 the current Decimal context.
2232
Thomas Woutersabd08882006-04-26 15:53:30 +00002233- regrtest.py now has a -M option to run tests that test the new limits of
2234 containers, on 64-bit architectures. Running these tests is only sensible
2235 on 64-bit machines with more than two gigabytes of memory. The argument
2236 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002244Documentation
2245-------------
2246
Tim Petersb06d28c2006-05-12 01:57:59 +00002247- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2248
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002249- PEP 343: Added Context Types section to the library reference
2250 and attempted to bring other PEP 343 related documentation into
2251 line with the implementation and/or python-dev discussions.
2252
Tim Peters8dc73d22006-04-24 02:03:16 +00002253- Bug #1337990: clarified that ``doctest`` does not support examples
2254 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002257What's New in Python 2.5 alpha 1?
2258=================================
2259
Anthony Baxterebed3f62006-04-03 15:03:44 +00002260*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002261
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002262Core and builtins
2263-----------------
2264
Nick Coghlan43832302006-04-23 17:04:07 +00002265- PEP 338: -m command line switch now delegates to runpy.run_module
2266 allowing it to support modules in packages and zipfiles
2267
Martin v. Löwisc661b882006-04-20 04:54:23 +00002268- On Windows, .DLL is not an accepted file name extension for
2269 extension modules anymore; extensions are only found if they
2270 end in .PYD.
2271
Martin v. Löwisea62d252006-04-03 10:56:49 +00002272- Bug #1421664: sys.stderr.encoding is now set to the same value as
2273 sys.stdout.encoding.
2274
Neal Norwitz92e212f2006-04-03 04:48:37 +00002275- __import__ accepts keyword arguments.
2276
Georg Brandlccadf842006-03-31 18:54:53 +00002277- Patch #1460496: round() now accepts keyword arguments.
2278
Anthony Baxter262c00a2006-03-30 10:53:17 +00002279- Fixed bug #1459029 - unicode reprs were double-escaped.
2280
Hye-Shik Changd478f342006-03-23 12:32:36 +00002281- Patch #1396919: The system scope threads are reenabled on FreeBSD
2282 5.4 and later versions.
2283
Neal Norwitze98ccf62006-03-23 05:39:47 +00002284- Bug #1115379: Compiling a Unicode string with an encoding declaration
2285 now gives a SyntaxError.
2286
Georg Brandlabd1ff82006-03-18 07:59:59 +00002287- Previously, Python code had no easy way to access the contents of a
2288 cell object. Now, a ``cell_contents`` attribute has been added
2289 (closes patch #1170323).
2290
Tim Peterscf79aac2006-03-16 01:14:46 +00002291- Patch #1123430: Python's small-object allocator now returns an arena to
2292 the system ``free()`` when all memory within an arena becomes unused
2293 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2294 freed. Some applications will see a drop in virtual memory size now,
2295 especially long-running applications that, from time to time, temporarily
2296 use a large number of small objects. Note that when Python returns an
2297 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002298 platform C library will in turn return that memory to the operating system.
2299 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002300 appears to be effective at least on Microsoft C and gcc-based systems.
2301 Thanks to Evan Jones for hard work and patience.
2302
Georg Brandl533ff6f2006-03-08 18:09:27 +00002303- Patch #1434038: property() now uses the getter's docstring if there is
2304 no "doc" argument given. This makes it possible to legitimately use
2305 property() as a decorator to produce a read-only property.
2306
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002307- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2308 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2309 of requiring an int or long in slicing and a few other contexts, enabling
2310 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2311
Neal Norwitz995acdf2006-03-07 05:01:00 +00002312- Fixed various bugs reported by Coverity's Prevent tool.
2313
Brett Cannonbf364092006-03-01 04:25:17 +00002314- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2315 new exception base class, BaseException, which has a new message attribute.
2316 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2317 Raising a string exception now raises a DeprecationWarning.
2318
Thomas Woutersfb609f42006-02-28 16:37:25 +00002319- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2320 explicitly relative, using 'from .module import name' to mean 'from the same
2321 package as this module is in. Imports without dots still default to the
2322 old relative-then-absolute, unless 'from __future__ import
2323 absolute_import' is used.
2324
Brett Cannona7446e32006-02-27 23:39:10 +00002325- Properly check if 'warnings' raises an exception (usually when a filter set
2326 to "error" is triggered) when raising a warning for raising string
2327 exceptions.
2328
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002329- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002330 The name was removed from Include/code.h.
2331
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002332- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002333
Guido van Rossum1968ad32006-02-25 22:38:04 +00002334- Patch 1433928:
2335 - The copy module now "copies" function objects (as atomic objects).
2336 - dict.__getitem__ now looks for a __missing__ hook before raising
2337 KeyError.
2338
Tim Peters84ef21c2006-02-28 20:39:06 +00002339- PEP 343: with statement implemented. Needs ``from __future__ import
2340 with_statement``. Use of 'with' as a variable will generate a warning.
2341 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002342 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002343 The following objects have __context__ methods:
2344 - The built-in file type.
2345 - The thread.LockType type.
2346 - The following types defined by the threading module:
2347 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2348 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002349
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002350- Fix the encodings package codec search function to only search
2351 inside its own package. Fixes problem reported in patch #1433198.
2352
2353 Note: Codec packages should implement and register their own
2354 codec search function. PEP 100 has the details.
2355
Tim Peters9ea89d22006-06-04 03:26:02 +00002356- PEP 353: Using ``Py_ssize_t`` as the index type.
2357
2358- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2359 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2360 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2361 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2362 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002363
Neal Norwitzfc76d632006-01-10 06:03:13 +00002364- Patch #1400181, fix unicode string formatting to not use the locale.
2365 This is how string objects work. u'%f' could use , instead of .
2366 for the decimal point. Now both strings and unicode always use periods.
2367
Neal Norwitz671b9e32006-01-09 07:07:12 +00002368- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2369 configure would break checking curses.h.
2370
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002371- Bug #959576: The pwd module is now builtin. This allows Python to be
2372 built on UNIX platforms without $HOME set.
2373
Neal Norwitzc10978f2005-12-19 06:07:16 +00002374- Bug #1072182, fix some potential problems if characters are signed.
2375
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002376- Bug #889500, fix line number on SyntaxWarning for global declarations.
2377
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002378- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2379
Neal Norwitze7214a12005-12-18 05:03:17 +00002380- Support for converting hex strings to floats no longer works.
2381 This was not portable. float('0x3') now raises a ValueError.
2382
Barry Warsaw2a38a862005-12-18 01:27:35 +00002383- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002384 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002385 is now displayed in interactive prompt banner.
2386
Georg Brandlfa166682005-12-17 21:45:17 +00002387- Implementation of PEP 341 - Unification of try/except and try/finally.
2388 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002389 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002390
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002391- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2392 now encodes backslash correctly.
2393
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002394- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2395
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002396- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002397 and long longs.
2398
Neal Norwitz67715f02005-11-09 06:59:35 +00002399- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002400 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002401 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002402
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002403- Replaced most Unicode charmap codecs with new ones using the
2404 new Unicode translate string feature in the builtin charmap
2405 codec; the codecs were created from the mapping tables available
2406 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2407 encodings now include a mapping for the Apple logo)
2408
Tim Peterse3547fd2005-12-16 23:13:57 +00002409- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002410
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002411- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002412
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002413- A new AST parser implementation was completed. The abstract
2414 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002415 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002416
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002417- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002418 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2419
Neal Norwitz708e51a2005-10-03 04:48:15 +00002420- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2421
Neal Norwitz11bd1192005-10-03 00:54:56 +00002422- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2423 Provide a warning when a directory is passed on the command line.
2424
Neal Norwitz40d37812005-10-02 01:48:49 +00002425- Fix segfault with invalid coding.
2426
2427- SF bug #772896: unknown encoding results in MemoryError.
2428
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002429- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002430 supported a __len__() method which evaluated to False when the iterator
2431 was empty.
2432
Guido van Rossum630db602005-09-20 18:49:54 +00002433- On 64-bit platforms, when __len__() returns a value that cannot be
2434 represented as a C int, raise OverflowError.
2435
Skip Montanarof8948ca2005-09-19 03:54:46 +00002436- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002437 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002438
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002439- SF bug #893549: parsing keyword arguments was broken with a few format
2440 codes.
2441
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002442- Changes donated by Elemental Security to make it work on AIX 5.3
2443 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2444 bug #105470: test_pwd fails on 64bit system (Opteron).
2445
Guido van Rossum539c6622005-09-14 17:49:54 +00002446- Changes donated by Elemental Security to make it work on HP-UX 11 on
2447 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2448
Georg Brandl4550b8d2005-08-26 06:43:52 +00002449- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002450 (fixes bug #1119418).
2451
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002452- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2453
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002454- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2455 exceptions that cause a function to exit.
2456
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002457- The implementation of set() and frozenset() was revised to use its
2458 own internal data structure. Memory consumption is reduced by 1/3
2459 and there are modest speed-ups as well. The API is unchanged.
2460
Tim Petersde7990b2005-07-17 23:45:23 +00002461- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2462
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002463- SF bug #1229429: PyObject_CallMethod failed to decrement some
2464 reference counts in some error exit cases.
2465
Tim Petersecc6e6a2005-07-10 22:30:55 +00002466- SF bug #1185883: Python's small-object memory allocator took over
2467 a block managed by the platform C library whenever a realloc specified
2468 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002469 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002470 portable way to copy data from the C-managed block into Python's
2471 small-object space without risking a memory fault. Python's small-object
2472 realloc now leaves such blocks under the control of the platform C
2473 realloc.
2474
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002475- SF bug #1232517: An overflow error was not detected properly when
2476 attempting to convert a large float to an int in os.utime().
2477
Raymond Hettinger3296e692005-06-29 23:29:56 +00002478- SF bug #1224347: hex longs now print with lowercase letters just
2479 like their int counterparts.
2480
Michael W. Hudson188d4362005-06-20 16:52:57 +00002481- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2482 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2483 interpreter states; back out that fix and do a better job (see
2484 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2485 for a longer write-up of the problem).
2486
Michael W. Hudsondf888462005-06-03 14:41:55 +00002487- SF patch #1180995: marshal now uses a binary format by default when
2488 serializing floats.
2489
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002490- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2491 the routines that promise to produce IEEE 754 binary representations
2492 of floats now simply copy bytes around.
2493
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002494- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2495 278.
2496
Brett Cannonc3647ac2005-04-26 03:45:26 +00002497- patch #1109424: int, long, float, complex, and unicode now check for the
2498 proper magic slot for type conversions when subclassed. Previously the
2499 magic slot was ignored during conversion. Semantics now match the way
2500 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002501 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002502 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002503 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002504
Barry Warsawc8d907c2005-04-19 23:43:40 +00002505- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2506 NULL, now raise an AttributeError when attempting to set or delete the
2507 attribute. Previously a TypeError was raised, but this was inconsistent
2508 with the equivalent pure-Python implementation.
2509
Michael W. Hudson774479c2005-04-18 08:46:17 +00002510- It is now safe to call PyGILState_Release() before
2511 PyEval_InitThreads() (note that if there is reason to believe there
2512 are multiple threads around you still must call PyEval_InitThreads()
2513 before using the Python API; this fix is for extension modules that
2514 have no way of knowing if Python is multi-threaded yet).
2515
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002516- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2517 disabled caused a crash.
2518
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002519- Bug #1165306: instancemethod_new allowed the creation of a method
2520 with im_class == im_self == NULL, which caused a crash when called.
2521
Tim Petersecc6e6a2005-07-10 22:30:55 +00002522- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002523 fixes the crash seen in bug #1165761
2524
Raymond Hettinger96229b12005-03-11 06:49:40 +00002525- Added two new builtins, any() and all().
2526
Brett Cannon409d8f22005-03-05 06:47:57 +00002527- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002528 (e.g., ``class C(): pass`` is no longer a syntax error).
2529 Patch #1176012 added support to the 'parser' module and 'compiler' package
2530 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002531
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002532- Patch #1115086: Support PY_LONGLONG in structmember.
2533
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002534- Bug #1155938: new style classes did not check that __init__() was
2535 returning None.
2536
Tim Petersecc6e6a2005-07-10 22:30:55 +00002537- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002538 ('\') with a specific error message.
2539
Martin v. Löwisff232d72005-03-03 09:24:38 +00002540- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2541
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002542- Bug #1124295: the __name__ attribute of file objects was
2543 inadvertently made inaccessible in restricted mode.
2544
Tim Petersecc6e6a2005-07-10 22:30:55 +00002545- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002546 an ferror() call.
2547
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002548- min() and max() now support key= arguments with the same meaning as in
2549 list.sort().
2550
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002551- The peephole optimizer now performs simple constant folding in expressions:
2552 (2+3) --> (5).
2553
Raymond Hettingera422c342005-01-11 03:03:27 +00002554- set and frozenset objects can now be marshalled. SF #1098985.
2555
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002556- Bug #1077106: Poor argument checking could cause memory corruption
2557 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002558
Jeremy Hyltonab630502005-02-04 18:44:06 +00002559- The parser did not complain about future statements in illegal
2560 positions. It once again reports a syntax error if a future
2561 statement occurs after anything other than a doc string.
2562
Neil Schemenauercf52c072005-08-12 17:34:58 +00002563- Change the %s format specifier for str objects so that it returns a
2564 unicode instance if the argument is not an instance of basestring and
2565 calling __str__ on the argument returns a unicode instance.
2566
Tim Petersf4e69282006-02-27 17:15:31 +00002567- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2568 current thread state when the auto-GIL-state machinery knows about
2569 it (since the thread state is being deleted, continuing to remember it
2570 can't help, but can hurt if another thread happens to get created with
2571 the same thread id).
2572
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002573Extension Modules
2574-----------------
2575
Georg Brandl43f08a82006-03-31 18:01:16 +00002576- Patch #1380952: fix SSL objects timing out on consecutive read()s
2577
Neal Norwitz05a45592006-03-20 06:30:08 +00002578- Patch #1309579: wait3 and wait4 were added to the posix module.
2579
Anthony Baxterfa869072006-03-20 05:21:58 +00002580- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2581 In addition, the existing ulaw code was updated.
2582
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002583- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002584 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002585
Neal Norwitz10be10c2006-03-16 06:50:13 +00002586- Everything under lib-old was removed. This includes the following modules:
2587 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002588 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002589 util, whatsound, whrandom, zmod
2590
2591- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2592
2593- re and sre were swapped, so help(re) provides full help. importing sre

2749
Raymond Hettingerb2594052004-12-05 09:25:51 +00002750- itertools.islice() now accepts None for the start and step arguments.
2751 This allows islice() to work more readily with slices:
2752 islice(s.start, s.stop, s.step)
2753
Skip Montanaro0af3ade2005-01-13 04:12:31 +00002754- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002763- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2764 been renamed to have only a single underscore prefix. This was done to
2765 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002766
Nick Coghlan43832302006-04-23 17:04:07 +00002767- PEP 338: new module runpy defines a run_module function to support
2768 executing modules which provide access to source code or a code object
2769 via the PEP 302 import mechanisms.
2770
Anthony Baxter93f5b932006-04-03 08:05:07 +00002771- The email module's parsedate_tz function now sets the daylight savings

2779 in attribute values.
2780
Anthony Baxterc51ee692006-04-01 00:57:31 +00002781- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002782 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002783 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002784 module will not be built.
2785
Tim Petersc17976e2006-04-01 00:26:53 +00002786- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2787 aren't officially supported here, and trying to use them will probably
2788 raise an exception some day. But dicts have been allowed, and "mostly
2789 worked", so support for them won't go away without warning.
2790
Georg Brandl338ef7d2006-03-31 18:42:16 +00002791- Bug #1445068: getpass.getpass() can now be given an explicit stream
2792 argument to specify where to write the prompt.
2793

2809
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002810- email 4.0 package now integrated. This is largely the same as the email 3.0
2811 package that was included in Python 2.3, except that PEP 8 module names are
2812 now used (e.g. mail.message instead of email.Message). The MIME classes
2813 have been moved to a subpackage (e.g. email.mime.text instead of
2814 email.MIMEText). The old names are still supported for now. Several
2815 deprecated Message methods have been removed and lots of bugs have been
2816 fixed. More details can be found in the email package documentation.
2817
Walter Dörwald40108c92006-03-27 08:15:44 +00002818- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2819 (a subclass of tuple) that provides incremental decoders and encoders
2820 (a way to use stateful codecs without the stream API). Python functions
2821 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2822 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2823 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002825- Patch #1359365: Calling next() on a closed StringIO.String object raises
2826 a ValueError instead of a StopIteration now (like file and cString.String do).
2827 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2828 called before (like file and StringIO.StringIO do).

2898 LoadError as documented, instead of IOError. For compatibility,
2899 LoadError subclasses IOError.
2900
Brett Cannon3cbd0382005-12-16 22:49:23 +00002901- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002902 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2903 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2904 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2905 Ronald L. Rivest offered this advice for Python:
2906
2907 "The consensus of researchers in this area (at least as
2908 expressed at the NIST Hash Function Workshop 10/31/05),
2909 is that SHA-256 is a good choice for the time being, but
2910 that research should continue, and other alternatives may
2911 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002912
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002913- Added a subset of Fredrik Lundh's ElementTree package. Available

Walter Dörwalda05834e2005-10-09 19:38:21 +00002967 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002968

3031 allows other classes to implement __radd__ style methods and have them
3032 work as expected.
3033
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003034- Bug #1163325: Decimal infinities failed to hash. Attempting to

Guido van Rossumd0641422005-02-03 15:01:24 +00003072- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3073 disables recursive traversal through instance attributes, which can
3074 be exploited in various ways.
3075
Tim Peterse3547fd2005-12-16 23:13:57 +00003076- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec

3090
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003091- Enhancements to the csv module:
3092
3093 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003094 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003095 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003096 + Dialect parameter parsing has been re-implemented to improve error
3097 reporting.
3098 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3099 dictates.
3100 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003101 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003102 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003103 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3104 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003105 + reader now allows \r characters to be quoted (previously it only allowed
3106 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003107 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003108 + Dialect classes passed to the module are no longer instantiated by
3109 the module before being parsed (the former validation scheme required
3110 this, but the mechanism was unreliable).
3111 + The dialect registry now contains instances of the internal
3112 C-coded dialect type, rather than references to python objects.
3113 + the internal c-coded dialect type is now immutable.
3114 + register_dialect now accepts the same keyword dialect specifications
3115 as the reader and writer, allowing the user to register dialects
3116 without first creating a dialect class.
3117 + a configurable limit to the size of parsed fields has been added -
3118 previously, an unmatched quote character could result in the entire
3119 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003120 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003121 the parser field size limit (returning the former limit). The initial
3122 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003123 + A line_num attribute has been added to the reader object, which tracks
3124 the number of lines read from the source iterator. This is not
3125 the same as the number of records returned, as records can span
3126 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003127 + reader and writer objects were not being registered with the cyclic-GC.
3128 This has been fixed.
3129
Brett Cannone6539c42005-01-08 02:43:53 +00003130- _DummyThread objects in the threading module now delete self.__block that is
3131 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3132 lock primitives tend to be limited in number and thus should not be wasted on
3133 a _DummyThread object. Fixes bug #1089632.
3134
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003135- The imghdr module now detects Exif files.
3136
Raymond Hettinger6065d322004-12-20 23:51:53 +00003137- StringIO.truncate() now correctly adjusts the size attribute.
3138 (Bug #951915).
3139
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003140- locale.py now uses an updated locale alias table (built using
3141 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3142 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003143 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003144
Raymond Hettinger3557f422004-12-07 12:02:02 +00003145- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3146
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003147- the pickle module no longer accepts the deprecated None option in the
3148 args tuple returned by __reduce__().
3149
Brett Cannon84667c02004-12-07 03:25:18 +00003150- optparse now optionally imports gettext. This allows its use in setup.py.
3151
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003152- the pickle module no longer uses the deprecated bin parameter.
3153
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003154- the shelve module no longer uses the deprecated binary parameter.
3155
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003156- the pstats module no longer uses the deprecated ignore() method.
3157
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003158- the filecmp module no longer uses the deprecated use_statcache argument.
3159
Raymond Hettinger664347b2004-12-04 21:21:53 +00003160- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3161 extended or overridden by subclasses. Formerly, the subclassed method would
3162 be ignored by the rest of the module. (Bug #1078905).
3163
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003164- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003165 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003166
Walter Dörwald36733692004-12-22 12:50:50 +00003167- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3168 once when a size argument is given. This prevents a buffer overflow in the
3169 tokenizer with very long source lines.
3170
Barry Warsaw538561e2006-01-01 21:48:54 +00003171- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3172 immediately after creating the object, without any intervening
3173 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003174
Skip Montanaro05885812005-01-16 20:48:27 +00003175- The reconvert.quote function can now emit triple-quoted strings. The
3176 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003177
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003178- ``UserString.MutableString`` now supports negative indices in
3179 ``__setitem__`` and ``__delitem__``
3180
Greg Ward40407942005-03-05 02:53:17 +00003181- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3182 correctly.
3183
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003184- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3185 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3186 character even if the user has passed a size parameter to get a proper
3187 line ending. Remove the special handling of a "\r\n" that has been split
3188 between two lines.
3189
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003190- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3191 about illegal code points. The codec now supports PEP 293 style error
3192 handlers.
3193
Walter Dörwald78a78b02005-09-01 12:04:29 +00003194- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003195 from the input stream, so that the output is a byte string in the correct
3196 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003197
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003198- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3199 considering it exactly like a '*'.
3200
Walter Dörwald007f8df2005-10-09 19:42:27 +00003201- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3202 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003203
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003204- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3205
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003206- Patch #1413711: Certain patterns of differences were making difflib
3207 touch the recursion limit.
3208
Walter Dörwald58917a62006-03-31 15:26:22 +00003209- Bug #947906: An object oriented interface has been added to the calendar
3210 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003211 called as a script (e.g. via ``python -mcalendar``). Localized month and
3212 weekday names can be ouput (even if an exotic encoding is used) using
3213 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003214
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003215Build
3216-----
3217
Neal Norwitz602d3392006-03-31 08:21:40 +00003218- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3219 by using -mieee gcc option.
3220
Martin v. Löwis86d66262006-02-17 08:40:11 +00003221- Patch #1432345: Make python compile on DragonFly.
3222
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003223- Build support for Win64-AMD64 was added.
3224
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003225- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3226
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003227- Patch #881820: look for openpty and forkpty also in libbsd.
3228
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003229- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3230 The zlib module is now builtin on Windows.
3231
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003232- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3233
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003234- Bug #1189330: configure did not correctly determine the necessary
3235 value of LINKCC if python was built with GCC 4.0.
3236
Trent Mick8321b422005-07-26 02:29:21 +00003237- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3238 vulnerability in zlib 1.2.1 and 1.2.2.
3239
Brett Cannon08cd5982005-04-24 22:26:38 +00003240- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3241 flags that change binary compatibility. Changes were also made to
3242 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003243 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003244
Bob Ippolitoed233462005-03-29 13:47:59 +00003245- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3246 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3247 no longer exists). This configure patch makes things right.
3248
Martin v. Löwise2713be2005-03-08 15:03:08 +00003249- Bug #1158607: Build with --disable-unicode again.
3250
Brett Cannon46d96232005-02-16 00:07:19 +00003251- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3252 defined. Discovered as a result of not being able to build on OS X.
3253
Brett Cannon516592f2004-12-07 00:42:59 +00003254- setup.py now uses the directories specified in LDFLAGS using the -L option
3255 and in CPPFLAGS using the -I option for adding library and include
3256 directories, respectively, for compiling extension modules against. This has
3257 led to the core being compiled using the values in CPPFLAGS. It also removes
3258 the need for the special-casing of both DarwinPorts and Fink for darwin since
3259 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3260 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3261 Fink, ``-I/opt/local/include`` for DarwinPorts).
3262
Brett Cannon43802422005-02-10 20:48:03 +00003263- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3264 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3265 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3266 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003268C API
3269-----
3270
Tim Petersc9d78aa2006-03-26 23:27:58 +00003271- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3272 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3273 is obtained via the ``PyObject_`` family, it must be released via the
3274 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3275 always been officially true, but when Python's small-object allocator was
3276 introduced, an attempt was made to cater to a few extension modules
3277 discovered at the time that obtained memory via ``PyObject_New`` but
3278 released it via ``PyMem_DEL``. It's years later, and if such code still
3279 exists it will fail now (probably with segfaults, but calling wrong
3280 low-level memory management functions can yield many symptoms).
3281
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003282- Added a C API for set and frozenset objects.
3283
Raymond Hettinger66517482004-12-03 11:45:13 +00003284- Removed PyRange_New().
3285
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003286- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3287 mapping argument now. This string is used as a mapping table. Byte values
3288 greater than the length of the string and 0xFFFE are treated as undefined
3289 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003296
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003297- Patch #1276356: New resource "urlfetch" is implemented. This enables
