12Core and builtins
13-----------------
14
Christian Heimes1beea3b2008-01-03 15:41:30 +000015- Issue #1726: Remove Python/atof.c from PCBuild/pythoncore.vcproj
16
Christian Heimesd9fbab22008-01-02 17:43:40 +000017- Removed PCbuild8/ directory and added a new build directory for VS 2005
18 based on the VS 2008 build directory to PC/VS8.0. The script
19 PCbuild/vs8to9.py was added to sync changes from PCbuild to PC/VS8.0.
20
Christian Heimes3adfe9a2007-12-31 15:18:55 +000021- Moved PCbuild/ directory for VS 2003 to PC/VS7.1 and renamed PCBuild9/
22 directory to PCBuild/.
23
Christian Heimese93237d2007-12-19 02:37:44 +000024- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE
25 and Py_REFCNT.
26
Christian Heimes0a8143f2007-12-18 23:22:54 +000027- Issue #1635: Platform independent creation and representation of NaN
28 and INF. float("nan"), float("inf") and float("-inf") now work on every
29 platform with IEEE 754 semantics.
30
31- Added case insensitive comparsion methods ``PyOS_stricmp(char*, char*)``
32 and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
33
Raymond Hettingerfd7ed402007-12-18 21:24:09 +000034- Compiler now generates simpler and faster code for dictionary literals.
35 The oparg for BUILD_MAP now indicates an estimated dictionary size.
36 There is a new opcode, STORE_MAP, for adding entries to the dictionary.
37
Christian Heimesdb3d6cb2007-12-16 21:39:43 +000038- Issue #1638: %zd configure test fails on Linux
39
Christian Heimes90e10e72007-12-14 02:35:23 +000040- Issue #1620: New property decorator syntax was modifying the decorator
41 in place instead of creating a new decorator object.
42
Christian Heimes284d9272007-12-10 22:28:56 +000043- Issue #1580: New free format floating point representation based on
44 "Floating-Point Printer Sample Code", by Robert G. Burger. For example
45 repr(11./5) now returns '2.2' instead of '2.2000000000000002'.
46
Skip Montanaro26015492007-12-08 15:33:24 +000047- Issue #1538: Avoid copying string in split/rsplit if the split
48 char is not found.
49
Andrew M. Kuchling395fe442007-12-05 13:27:20 +000050- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +000051 SystemError.
52
Nick Coghlanef01d822007-12-03 12:55:17 +000053- PEP 366: Allow explicit relative imports when executing modules
54 inside packages with the -m switch via a new module level
55 __package__ attribute.
56
Christian Heimesdfdfaab2007-12-01 11:20:10 +000057- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
58 ``PyFloat_GetInfo()`` to the float API.
59
Amaury Forgeot d'Arcdafd32b2007-11-30 20:51:40 +000060- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
61 format code incorrectly truncated the length to an int, even when
62 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
63 results with huge strings.
64
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +000065- Issue #1402: Fix a crash on exit, when another thread is still running, and
66 if the deallocation of its frames somehow calls the PyGILState_Ensure() /
67 PyGILState_Release() functions.
68
Christian Heimes28104c52007-11-27 23:16:44 +000069- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
70
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +000071- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
72 attribute of an empty cell object.
73
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +000074- Issue #1460: The utf-7 incremental decoder did not accept truncated input.
75 It now correctly saves its state between chunks of data.
76
Nick Coghlan327a39b2007-11-18 11:56:28 +000077- Patch #1739468: Directories and zipfiles containing a __main__.py file can
78 now be directly executed by passing their name to the interpreter. The
79 directory/zipfile is automatically inserted as the first entry in sys.path.
80
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +000081- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
82 generator expression when at the same time the executed code is closing a
83 paused generator.
84
Raymond Hettinger1760c8a2007-11-08 02:52:43 +000085- sets and frozensets now have an isdisjoint() method.
86
Raymond Hettinger3f8caa32007-10-24 01:28:33 +000087- optimize the performance of builtin.sum().
88
Neal Norwitz44f326e2007-10-05 05:29:17 +000089- Fix warnings found by the new version of the Coverity checker.
90
Raymond Hettinger8f669372007-10-03 21:18:11 +000091- The enumerate() builtin function is no longer bounded to sequences smaller
92 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
93 shifts from ints to longs.
94
Brett Cannon0b14f242007-09-30 19:45:10 +000095- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
96 having a self-referential tuple, which is possible from C code. Nor did
97 object's tp_str consider that a type's tp_str could do something that could
98 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
99 respectively, fixed the issues.
100
Brett Cannon01531592007-09-17 03:28:34 +0000101- Issue #1164: It was possible to trigger deadlock when using the 'print'
102 statement to write to a file since the GIL was not released as needed. Now
103 PyObject_Print() does the right thing along with various tp_print
104 implementations of the built-in types and those in the collections module.
105
Brett Cannon4c20bc42007-09-11 21:02:28 +0000106- Issue #1147: Exceptions were directly allowing string exceptions in their
107 throw() method even though string exceptions no longer allowed.
108
Brett Cannona0c05512007-09-10 21:38:27 +0000109- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
110 list by using the recursion counter.
111
Brett Cannon1e534b52007-09-07 04:18:30 +0000112- Issue #1202533: Fix infinite recursion calls triggered by calls to
113 PyObject_Call() never calling back out to Python code to trigger recursion
114 depth updates/checks. Required the creation of a static RuntimeError
115 instance in case normalizing an exception put the recursion check value past
116 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
117
Martin v. Löwisa5136192007-09-04 14:19:28 +0000118- Patch #1031213: Decode source line in SyntaxErrors back to its original source
119 encoding.
120
Neal Norwitz766d8802007-08-03 06:46:29 +0000121- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
122
Martin v. Löwis68192102007-07-21 06:55:02 +0000123- PEP 3123: Provide forward compatibility with Python 3.0, while keeping
124 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
125 PyVarObject_HEAD_INIT.
126
Georg Brandl7c3b50d2007-07-12 08:38:00 +0000127- Patch #1673759: add a missing overflow check when formatting floats
128 with %G.
129
Martin v. Löwis6371cd82007-06-09 07:42:52 +0000130- Patch #1733960: Allow T_LONGLONG to accept ints.
131
Walter Dörwald84a3efe2007-06-13 16:57:12 +0000132- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
133
Neal Norwitzdb2b1b32007-06-11 07:36:24 +0000134- Prevent expandtabs() on string and unicode objects from causing a segfault
135 when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +0000136
Martin v. Löwisda587ab2007-06-08 17:29:20 +0000137- Bug #1733488: Fix compilation of bufferobject.c on AIX.
138
Georg Brandl25497a12007-06-01 19:20:27 +0000139- Bug #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +0000140
Neal Norwitz0ac60192007-05-27 04:08:54 +0000141- Add new attribute names for function objects. All the func_* become
142 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
143
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +0000144- Add -3 option to the interpreter to warn about features that are
145 deprecated and will be changed/removed in Python 3.0.
146
Georg Brandl2134e752007-05-21 20:34:16 +0000147- Patch #1686487: you can now pass any mapping after '**' in function
148 calls.
149
Collin Winter62903052007-05-18 23:11:24 +0000150- except clauses may now be spelled either "except E, target:" or
151 "except E as target:". This is to provide forwards compatibility with
152 Python 3.0.
153
Brett Cannon229cee22007-05-05 01:34:02 +0000154- Deprecate BaseException.message as per PEP 352.
155
Armin Rigo9790a272007-05-02 19:23:31 +0000156- Bug #1303614: don't expose object's __dict__ when the dict is
157 inherited from a builtin base.
158
Vinay Sajip8549ce32007-05-06 17:53:37 +0000159- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +0000160 setting a plain string, ie don't expand to single letter identifiers.
161
Raymond Hettinger13936692007-04-11 18:40:58 +0000162- Request #1191699: Slices can now be pickled.
163
Raymond Hettinger4db5fe92007-04-12 04:10:00 +0000164- Request #1193128: str.translate() now allows a None argument for
165 translations that only remove characters without re-mapping the
166 remaining characters.
167
Georg Brandl5cb76c12007-03-21 09:00:39 +0000168- Patch #1682205: a TypeError while unpacking an iterable is no longer
169 masked by a generic one with the message "unpack non-sequence".
170
Neal Norwitzaa754b72007-03-21 06:39:48 +0000171- Remove unused file Python/fmod.c.
172
Guido van Rossum143b5642007-03-23 04:58:42 +0000173- Bug #1683368: The object.__init__() and object.__new__() methods are
174 now stricter in rejecting excess arguments. The only time when
175 either allows excess arguments is when it is not overridden and the
176 other one is. For backwards compatibility, when both are
177 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +0000178 warning later). Also, type.__init__() insists on the same signature
179 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +0000180
Georg Brandl2b869942007-03-17 16:08:45 +0000181- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
182 to complex using its __complex__() method before falling back to the
183 __float__() method. Therefore, the functions in the cmath module now
184 can operate on objects that define a __complex__() method.
185
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +0000186- Patch #1623563: allow __class__ assignment for classes with __slots__.
187 The old and the new class are still required to have the same slot names.
188
Collin Winter77c67bd2007-03-16 04:11:30 +0000189- Patch #1642547: Fix an error/crash when encountering syntax errors in
190 complex if statements.
191
Žiga Seilnacht20f43d32007-03-15 11:44:55 +0000192- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
193 is called with an object that is faking its type.
194
Žiga Seilnacht71436f02007-03-14 12:24:09 +0000195- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
196 name.
197
Georg Brandl5240d742007-03-13 20:46:32 +0000198- Patch #1444529: the builtin compile() now accepts keyword arguments.
199
Georg Brandl7b9c5552007-03-12 14:30:05 +0000200- Bug #1678647: write a newline after printing an exception in any
201 case, even when converting the value to a string failed.
202
Georg Brandl871f1bc2007-03-12 13:17:36 +0000203- The dir() function has been extended to call the __dir__() method on
204 its argument, if it exists. If not, it will work like before. This allows
205 customizing the output of dir() in the presence of a __getattr__().
206
Collin Winter276887b2007-03-12 16:11:39 +0000207- Patch #922167: Python no longer segfaults when faced with infinitely
208 self-recursive reload() calls (as reported by bug #742342).
209
Žiga Seilnacht89032082007-03-11 15:54:54 +0000210- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
211
Collin Wintere38051d2007-03-09 20:33:07 +0000212- Patch #1491866: change the complex() constructor to allow parthensized
213 forms. This means complex(repr(x)) now works instead of raising a
214 ValueError.
215
Georg Brandlaa2321b2007-03-07 00:40:28 +0000216- Patch #703779: unset __file__ in __main__ after running a file. This
217 makes the filenames the warning module prints much more sensible when
218 a PYTHONSTARTUP file is used.
219
Georg Brandl49aafc92007-03-07 00:34:46 +0000220- Variant of patch #697613: don't exit the interpreter on a SystemExit
221 exception if the -i command line option or PYTHONINSPECT environment
222 variable is given, but break into the interactive interpreter just like
223 on other exceptions or normal program exit.
224
Georg Brandl00cd8182007-03-06 18:41:12 +0000225- Patch #1638879: don't accept strings with embedded NUL bytes in long().
226
Georg Brandl098cd692007-03-06 12:17:50 +0000227- Bug #1674503: close the file opened by execfile() in an error condition.
228
Georg Brandl0fca97a2007-03-05 22:28:08 +0000229- Patch #1674228: when assigning a slice (old-style), check for the
230 sq_ass_slice instead of the sq_slice slot.
231
Neal Norwitz88516a62007-02-26 22:41:45 +0000232- When printing an unraisable error, don't print exceptions. before the name.
233 This duplicates the behavior whening normally printing exceptions.
234
Martin v. Löwisfd963262007-02-09 12:19:32 +0000235- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
236
Brett Cannon129bd522007-01-30 21:34:36 +0000237- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
238 catch a string exception raises DeprecationWarning.
239
Brett Cannonf5bee302007-01-23 23:21:22 +0000240- Bug #1377858: Fix the segfaulting of the interpreter when an object created
241 a weakref on itself during a __del__ call for new-style classes (classic
242 classes still have the bug).
243
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000244- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
245 frame's thread state.
246
Thomas Wouters6ed19652007-01-23 13:50:49 +0000247- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
248
Martin v. Löwis4885e7d2007-01-19 06:42:22 +0000249- Bug #1637022: Prefix AST symbols with _Py_.
250
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000251- Prevent seg fault on shutdown which could occur if an object
252 raised a warning.
253
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000254- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
255 to avoid relying on atexit.
256
Raymond Hettinger94547f72006-12-20 06:42:06 +0000257- Bug #1590891: random.randrange don't return correct value for big number
258
Georg Brandl283a1352006-11-19 08:48:30 +0000259- Patch #1586791: Better exception messages for some operations on strings,
260 tuples and lists.
261
Martin v. Löwis056dac12006-11-12 18:24:26 +0000262- Bug #1067760: Deprecate passing floats to file.seek.
263
Martin v. Löwisa346c092006-11-08 06:48:36 +0000264- Bug #1591996: Correctly forward exception in instance_contains().

Neal Norwitz85dbec62006-11-04 19:25:22 +0000266- Bug #1588287: fix invalid assertion for `1,2` in debug builds.
267
Georg Brandlb9f4ad32006-10-29 18:31:42 +0000268- Bug #1576657: when setting a KeyError for a tuple key, make sure that
269 the tuple isn't used as the "exception arguments tuple".
270
Neal Norwitz21997af2006-10-28 21:19:07 +0000271- Bug #1565514, SystemError not raised on too many nested blocks.
272
Thomas Hellerdf08f0b2006-10-27 18:31:36 +0000273- Bug #1576174: WindowsError now displays the windows error code
274 again, no longer the posix error code.
275
Martin v. Löwisb5bc5372006-10-27 06:16:31 +0000276- Patch #1549049: Support long values in structmember, issue warnings
277 if the assigned value for structmember fields gets truncated.
278
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000279- Update the peephole optimizer to remove more dead code (jumps after returns)
280 and inline unconditional jumps to returns.
281
Georg Brandl2c1375c2006-10-12 11:27:59 +0000282- Bug #1545497: when given an explicit base, int() did ignore NULs
283 embedded in the string to convert.
284
Georg Brandl846f73a2006-10-08 07:11:54 +0000285- Bug #1569998: break inside a try statement (outside a loop) is now
286 recognized and rejected.
287
Armin Rigo7ccbca92006-10-04 12:17:45 +0000288- list.pop(x) accepts any object x following the __index__ protocol.
289
290- Fix some leftovers from the conversion from int to Py_ssize_t
291 (relevant to strings and sequences of more than 2**31 items).
292
293- A number of places, including integer negation and absolute value,
294 were fixed to not rely on undefined behaviour of the C compiler
295 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +0000296
Georg Brandl3267d282006-09-30 09:03:42 +0000297- Bug #1566800: make sure that EnvironmentError can be called with any

Collin Winterfaaa2042007-03-10 03:35:34 +0000622 be equal to calling getsockname() on the server's socket. Fixed by

Georg Brandl2c94bf72006-09-24 10:36:01 +0000887- Make webbrowser.BackgroundBrowser usable in Windows (it wasn't because

915
Neal Norwitz92422fb2006-08-18 03:57:54 +0000916Extension Modules

950 time so that opening a database previously created with the DB_DUP or
951 DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
952 Specifically: dictionary assignment to a DB object will replace all
953 values for a given key when the database allows duplicate values.
954 DB users should use DB.put(k, v) when they want to store duplicates; not
955 DB[k] = v.
956

1164
Guido van Rossum7c862f82007-12-13 20:50:10 +00001165- Bug #1608: use -fwrapv when GCC supports it. This is important,
1166 newer GCC versions may optimize away overflow buffer overflow checks
1167 without this option!
1168
Martin v. Löwis63bf1492007-11-12 05:14:05 +00001169- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.

1172 periodic threadstate and signal checking in tight loops. By default,
1173 this option is turned-off. It should only be enabled in debugged,
1174 performance critical applications.

1186
Georg Brandldb846032007-03-31 18:56:11 +00001187- Bug #1655392: don't add -L/usr/lib/pythonX.Y/config to the LDFLAGS
1188 returned by python-config if Python was built with --enable-shared
1189 because that prevented the shared library from being used.

Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001256- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001257 compared equal or unequal to a string and a UnicodeDecodeError
1258 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001259
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001260 Instead, the equal (==) and unequal (!=) comparison operators will
1261 now issue a UnicodeWarning and interpret the two objects as
1262 unequal. The UnicodeWarning can be filtered as desired using
1263 the warning framework, e.g. silenced completely, turned into an
1264 exception, logged, etc.
1265
1266 Note that compare operators other than equal and unequal will still
1267 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001268
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001269- Fix segfault when doing string formatting on subclasses of long.
1270
1271- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1272 with new-style classes.
1273
1274- Fix bug related to __len__ functions returning negative values with
1275 classic classes.
1276
1277- Patch #1538606, Fix __index__() clipping. There were some problems
1278 discovered with the API and how integers that didn't fit into Py_ssize_t
1279 were handled. This patch attempts to provide enough alternatives
1280 to effectively use __index__.
1281
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001282- Bug #1536021: __hash__ may now return long int; the final hash
1283 value is obtained by invoking hash on the long int.
1284
Thomas Hellerab1049c2006-08-08 17:37:00 +00001285- Bug #1536786: buffer comparison could emit a RuntimeWarning.

Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001287- Bug #1535165: fixed a segfault in input() and raw_input() when
1288 sys.stdin is closed.
1289
Thomas Heller74d36f02006-08-04 18:17:40 +00001290- On Windows, the PyErr_Warn function is now exported from
1291 the Python dll again.
1292
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001293- Bug #1191458: tracing over for loops now produces a line event
1294 on each iteration. Fixing this problem required changing the .pyc
1295 magic number. This means that .pyc files generated before 2.5c1
1296 will be regenerated.
1297
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001298- Bug #1333982: string/number constants were inappropriately stored
1299 in the byte code and co_consts even if they were not used, ie
1300 immediately popped off the stack.
1301
Georg Brandle9462c72006-08-04 18:03:37 +00001302- Fixed a reference-counting problem in property().

1306-------
1307
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001308- Fix a bug in the ``compiler`` package that caused invalid code to be
1309 generated for generator expressions.
1310
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001311- The distutils version has been changed to 2.5.0. The change to
1312 keep it programmatically in sync with the Python version running
1313 the code (introduced in 2.5b3) has been reverted. It will continue
1314 to be maintained manually as static string literal.
1315
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001316- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001317 and this cannot be converted to the required C type, an exception is
1318 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001319 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001320
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001321- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001322 an exception.
1323
Tim Petersc10c9d02006-09-05 02:18:09 +00001324- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001325 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001326 workarounds for clocks with low resolution, to stop the code yielding
1327 duplicate UUIDs.
1328
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001329- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1330 before raising SystemExit, allowing IDLE to honor quit() and exit().
1331
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001332- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1333
Georg Brandl7a1af772006-08-14 21:55:28 +00001334- Patch #1536071: trace.py should now find the full module name of a
1335 file correctly even on Windows.
1336
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001337- logging's atexit hook now runs even if the rest of the module has
1338 already been cleaned up.
1339
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001340- Bug #1112549, fix DoS attack on cgi.FieldStorage.

Neal Norwitzff4b63b2006-08-04 04:50:21 +00001342- Bug #1531405, format_exception no longer raises an exception if
1343 str(exception) raised an exception.
1344
Neil Schemenauer06ded092006-08-04 16:20:30 +00001345- Fix a bug in the ``compiler`` package that caused invalid code to be

Georg Brandl3335a7a2006-08-14 21:42:55 +00001354- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1355 raises the correct exceptions.
1356
Thomas Heller1ce433e2006-08-14 16:20:04 +00001357- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1358 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1359
Thomas Heller86720042006-08-14 11:17:48 +00001360- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1361 uses the _as_parameter_ attribute when objects are passed to foreign
1362 function calls. The ctypes version number was changed to 1.0.1.
1363
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001364- Bug #1530559, struct.pack raises TypeError where it used to convert.
1365 Passing float arguments to struct.pack when integers are expected
1366 now triggers a DeprecationWarning.

1417-----------------
1418
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001419- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001420 returned a long (see PEP 353).
1421
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001422- Bug #1515471: string.replace() accepts character buffers again.
1423
Neal Norwitz07aadb12006-07-30 06:55:48 +00001424- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1425 This provides the proper warning for struct.pack().
1426 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1427
Neal Norwitz0d62a062006-07-30 06:53:31 +00001428- Patch #1531113: Fix augmented assignment with yield expressions.
1429 Also fix a SystemError when trying to assign to yield expressions.
1430
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001431- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1432 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1433 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1434 excessive filesystem operations during imports.
1435
Tim Petersbc24eee2006-07-27 01:14:53 +00001436- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1437 operations on signed longs that are formally undefined by C.
1438 Unfortunately, at least one compiler now cares about that, so complicated
1439 the code to make that compiler happy again.
1440
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001441- Bug #1524310: Properly report errors from FindNextFile in os.listdir.

Neal Norwitz84be93b2006-07-16 01:50:38 +00001450- Bug #1512814, Fix incorrect lineno's when code within a function
1451 had more than 255 blank lines.
1452
Georg Brandl9dceedb2006-07-12 15:31:17 +00001453- Patch #1521179: Python now accepts the standard options ``--help`` and
1454 ``--version`` as well as ``/?`` on Windows.
1455
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001456- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001457 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001458 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001459
Tim Peters112aad32006-07-19 00:03:19 +00001460- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001461 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001462 new ``sys._current_frames()`` returns a dictionary with one entry,
1463 mapping the faux "thread id" 0 to the current frame.
1464
Ronald Oussoren3075e162006-07-25 20:28:55 +00001465- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

1469-------
1470
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001471- Correction of patch #1455898: In the mbcs decoder, set final=False
1472 for stream decoder, but final=True for the decode function.
1473
Georg Brandl07fec3a2006-08-01 18:49:24 +00001474- os.urandom no longer masks unrelated exceptions like SystemExit or
1475 KeyboardInterrupt.
1476
Tim Peters4643c2f2006-08-10 22:45:34 +00001477- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001478 shutil.copytree on Windows
1479
Georg Brandle34ac7c2006-07-30 11:07:23 +00001480- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1481 refers to file descriptors, not file objects.
1482
Tim Petersc10c9d02006-09-05 02:18:09 +00001483- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001484 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001485 #1513611, and probably others.
1486
Georg Brandledd9b0d2006-07-29 09:33:26 +00001487- Bug #1441397: The compiler module now recognizes module and function
1488 docstrings correctly as it did in Python 2.4.
1489
Tim Peters6f681472006-07-27 23:44:37 +00001490- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1491 lost that tests are sorted by name before being run. This rarely
1492 matters for well-written tests, but can create baffling symptoms if
1493 side effects from one test to the next affect outcomes. ``DocTestFinder``
1494 has been changed to sort the list of tests it returns.
1495
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001496- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001497 in sync with sys.version_info[:3].

Martin v. Löwis9298eff2006-07-26 12:12:56 +00001499- Bug #978833: Really close underlying socket in _socketobject.close.
1500
Georg Brandl8c036cc2006-08-20 13:15:39 +00001501- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1502 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001503
Georg Brandlcf0c1722006-07-26 07:23:32 +00001504- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1505 to recursive calls and call it with the failing package name.
1506
Martin v. Löwis0b483032006-07-25 09:53:12 +00001507- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1508
Georg Brandlc13c34c2006-07-24 14:09:56 +00001509- Patch #1515343: Fix printing of deprecated string exceptions with a
1510 value in the traceback module.
1511
Greg Ward48fae7a2006-07-23 16:05:51 +00001512- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1513
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001514- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1515
Brett Cannoncaebe222006-07-18 04:41:36 +00001516- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1517 argument tuple. For arguments where zero is illegal, the value is forced to
1518 the minimum value that is correct. This is to support an undocumented but
1519 common way people used to fill in inconsequential information in the time
1520 tuple pre-2.4.
1521
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001522- Patch #1220874: Update the binhex module for Mach-O.
1523
Barry Warsawb110bad2006-07-21 14:51:07 +00001524- The email package has improved RFC 2231 support, specifically for
1525 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1526 (name*0=<blah>) parameter continuations. This may change the types of
1527 values returned from email.message.Message.get_param() and friends.
1528 Specifically in some cases where non-encoded continuations were used,
1529 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1530 will just return the string (since non-encoded continuations don't have
1531 charset and language parts).
1532
1533 Also, whereas % values were decoded in all parameter continuations, they are
1534 now only decoded in encoded parameter parts.
1535
Ronald Oussoren3075e162006-07-25 20:28:55 +00001536- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1537
1538- Bug #1517996: IDLE now longer shows the default Tk menu when a
1539 path browser, class browser or debugger is the frontmost window on MacOS X
1540
Barry Warsaw00decd72006-07-27 23:43:15 +00001541- Patch #1520294: Support for getset and member descriptors in types.py,
1542 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1543 of an object against these built-in types and more importantly, for getting
1544 their docstrings printed in the interactive interpreter's help() function.

1548-----------------
1549
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001550- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1551 a socket operation on a socket with a timeout, the exception will be
1552 caught correctly. Previously, the exception was not caught.
1553
Thomas Heller1393d6a2006-07-28 21:43:20 +00001554- Patch #1529514: The _ctypes extension is now compiled on more
1555 openbsd target platforms.
1556
Tim Peters9cab5932006-07-28 00:30:00 +00001557- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1558 a memory leak, affecting pickles and deep copies.
1559
Tim Petersbc24eee2006-07-27 01:14:53 +00001560- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1562
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001563- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1564
Thomas Hellerce049a02006-07-14 17:51:14 +00001565- Patch #1521817: Index range checking on ctypes arrays containing
1566 exactly one element enabled again. This allows iterating over these
1567 arrays, without the need to check the array size before.
1568
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001569- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001570 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001571 /dev/null in certain cases; this is now fixed.
1572
Thomas Heller47d7a062006-07-12 08:43:47 +00001573- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1574 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001575
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001576- Because of a misspelled preprocessor symbol, ctypes was always
1577 compiled without thread support; this is now fixed.
1578
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001579- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1580 methods now allow their database parameter to be None as the
1581 sleepycat API allows.
1582
Matt Flemingec926502006-07-28 11:27:27 +00001583- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1584 bluetooth API compared with Linux and FreeBSD.
1585
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001586Tests
1587-----
1588
1589- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1590 how long the test file should take to play. Now accepts taking 2.93 secs
1591 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1592
Georg Brandl4793aa32006-07-28 18:31:39 +00001593- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1594 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1595 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001602Mac
1603---
1604
1605- PythonLauncher now works correctly when the path to the script contains
1606 characters that are treated specially by the shell (such as quotes).
1607
1608- Bug #1527397: PythonLauncher now launches scripts with the working directory
1609 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001610 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001611 expect.

1620-----------------
1621
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001622- Bug #1441486: The literal representation of -(sys.maxint - 1)
1623 again evaluates to a int object, not a long.
1624
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001625- Bug #1501934: The scope of global variables that are locally assigned
1626 using augmented assignment is now correctly determined.
1627
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001628- Bug #927248: Recursive method-wrapper objects can now safely
1629 be released.
1630
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001631- Bug #1417699: Reject locale-specific decimal point in float()
1632 and atof().
1633
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001634- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1635 omit a default "error" argument for NULL pointer. This allows
1636 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001637
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001638- Bug #1519018: 'as' is now validated properly in import statements.
1639
Neal Norwitz28746ab2006-07-09 22:14:42 +00001640- On 64 bit systems, int literals that use less than 64 bits are
1641 now ints rather than longs.
1642
Neal Norwitzed657552006-07-10 00:04:44 +00001643- Bug #1512814, Fix incorrect lineno's when code at module scope
1644 started after line 256.
1645
Tim Peters32a83612006-07-10 21:08:24 +00001646- New function ``sys._current_frames()`` returns a dict mapping thread
1647 id to topmost thread stack frame. This is for expert use, and is
1648 especially useful for debugging application deadlocks. The functionality
1649 was previously available in Fazal Majid's ``threadframe`` extension
1650 module, but it wasn't possible to do this in a wholly threadsafe way from
1651 an extension.

1660
Tim Peters32a83612006-07-10 21:08:24 +00001661- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001662 environment variable to be set in order to the SDK environment
1663 for finding the compiler, include files, etc.

Nick Coghlan2d792252006-07-06 13:47:18 +00001667- warnings.py now ignores ImportWarning by default
1668
Thomas Woutersadd19112006-07-05 11:03:49 +00001669- string.Template() now correctly handles tuple-values. Previously,
1670 multi-value tuples would raise an exception and single-value tuples would
1671 be treated as the value they contain, instead.
1672
Martin v. Löwisede77f52006-07-03 13:01:35 +00001673- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1675
Martin v. Löwis45482392006-07-03 12:28:58 +00001676- Bug #1267547: Put proper recursive setup.py call into the
1677 spec file generated by bdist_rpm.
1678
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001679- Bug #1514693: Update turtle's heading when switching between
1680 degrees and radians.
1681
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001682- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001683 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001684
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001685- Bug #1514703: Only setup canvas window in turtle when the canvas
1686 is created.
1687
Martin v. Löwis7596e832006-07-01 15:33:37 +00001688- Bug #1513223: .close() of a _socketobj now releases the underlying
1689 socket again, which then gets closed as it becomes unreferenced.
1690
Fred Drake10497c82006-06-29 02:57:48 +00001691- Bug #1504333: Make sgmllib support angle brackets in quoted
1692 attribute values.
1693
1694- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1695 sgmllib ('[' and ']' were not accepted).
1696
Georg Brandl1be63af2006-06-28 20:23:25 +00001697- Fix a bug in the turtle module's end_fill function.
1698
Brett Cannon53ab5b72006-06-22 16:49:14 +00001699- Bug #1510580: The 'warnings' module improperly required that a Warning
1700 category be either a types.ClassType and a subclass of Warning. The proper
1701 check is just that it is a subclass with Warning as the documentation states.
1702
Georg Brandlad29e632006-06-21 17:45:17 +00001703- The compiler module now correctly compiles the new try-except-finally
1704 statement (bug #1509132).
1705
Neal Norwitz60373cd2006-06-22 06:30:50 +00001706- The wsgiref package is now installed properly on Unix.
1707
Vinay Sajip28e57612006-07-01 10:45:20 +00001708- A bug was fixed in logging.config.fileConfig() which caused a crash on
1709 shutdown when fileConfig() was called multiple times.
1710
Gerhard Häring762fbd32006-07-02 17:48:30 +00001711- The sqlite3 module did cut off data from the SQLite database at the first
1712 null character before sending it to a custom converter. This has been fixed
1713 now.

1716-----------------
1717
Tim Peters112aad32006-07-19 00:03:19 +00001718- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1719 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1720 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001721
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001722- Assigning None to pointer type fields in ctypes structures possible
1723 overwrote the wrong fields, this is fixed now.
1724
1725- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1726 on non-Windows platforms.
1727
1728- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1729 integer or long, without range checking.
1730
1731- Patch #1517790: It is now possible to use custom objects in the ctypes
1732 foreign function argtypes sequence as long as they provide a from_param
1733 method, no longer is it required that the object is a ctypes type.
1734
1735- The '_ctypes' extension module now works when Python is configured
1736 with the --without-threads option.
1737
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001738- Bug #1513646: os.access on Windows now correctly determines write
1739 access, again.
1740
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001741- Bug #1512695: cPickle.loads could crash if it was interrupted with
1742 a KeyboardInterrupt.
1743
Neal Norwitza12aa882006-07-06 06:45:08 +00001744- Bug #1296433: parsing XML with a non-default encoding and
1745 a CharacterDataHandler could crash the interpreter in pyexpat.
1746
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001747- Patch #1516912: improve Modules support for OpenVMS.

1751
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001752- Automate Windows build process for the Win64 SSL module.
1753
Tim Peters32a83612006-07-10 21:08:24 +00001754- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001755 Previously, the slight difference could cause compilation errors of the
1756 'zlib' module on systems with more than one version of zlib.
1757
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001758- The MSI compileall step was fixed to also support a TARGETDIR
1759 with spaces in it.
1760
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001761- Bug #1517388: sqlite3.dll is now installed on Windows independent
1762 of Tcl/Tk.
1763
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001764- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001765 trying to be installed even though it's empty.

1771 to minimize resources (zombies).
1772
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001773Documentation
1774-------------
1775
Nick Coghlan2d792252006-07-06 13:47:18 +00001776- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1777 documentation for the warnings module.
1778
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001779- Patch #1509163: MS Toolkit Compiler no longer available.
1780
Neal Norwitz56640df2006-07-10 02:36:41 +00001781- Patch #1504046: Add documentation for xml.etree.

Nick Coghlanc649ec52006-05-29 12:43:05 +00001784What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001785================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001786
Anthony Baxterd1136802006-06-19 12:04:15 +00001787*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001788
1789Core and builtins
1790-----------------
1791
Georg Brandla56b9152006-06-19 06:35:54 +00001792- Patch #1507676: Error messages returned by invalid abstract object operations
1793 (such as iterating over an integer) have been improved and now include the
1794 type of the offending object to help with debugging.
1795
Brett Cannonea3912b2006-06-13 21:46:41 +00001796- Bug #992017: A classic class that defined a __coerce__() method that returned
1797 its arguments swapped would infinitely recurse and segfault the interpreter.
1798
Neal Norwitz909eb122006-06-12 02:13:21 +00001799- Fix the socket tests so they can be run concurrently.
1800
Neal Norwitzb9845e72006-06-12 02:11:18 +00001801- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001802 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001803
Brett Cannon22565aa2006-06-09 22:31:23 +00001804- Bug #532646: object.__call__() will continue looking for the __call__
1805 attribute on objects until one without one is found. This leads to recursion
1806 when you take a class and set its __call__ attribute to an instance of the
1807 class. Originally fixed for classic classes, but this fix is for new-style.
1808 Removes the infinite_rec_3 crasher.
1809
Georg Brandl24250812006-06-09 18:45:48 +00001810- The string and unicode methods startswith() and endswith() now accept
1811 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1812
Brett Cannonde3b0522006-06-08 17:00:45 +00001813- Buffer objects, at the C level, never used the char buffer
1814 implementation even when the char buffer for the wrapped object was
1815 explicitly requested (originally returned the read or write buffer).
1816 Now a TypeError is raised if the char buffer is not present but is
1817 requested.
1818
Georg Brandlddbaa662006-06-04 21:56:52 +00001819- Patch #1346214: Statements like "if 0: suite" are now again optimized
1820 away like they were in Python 2.4.
1821
Georg Brandlb7c8f542006-05-27 12:30:25 +00001822- Builtin exceptions are now full-blown new-style classes instead of
1823 instances pretending to be classes, which speeds up exception handling
1824 by about 80% in comparison to 2.5a2.
1825
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001826- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1827 Unicode 4.1.
1828
Georg Brandlf4ef1162006-05-26 18:03:31 +00001829- Patch #921466: sys.path_importer_cache is now used to cache valid and
1830 invalid file paths for the built-in import machinery which leads to
1831 fewer open calls on startup.
1832
Tim Peters696cf432006-05-24 21:10:40 +00001833- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1834 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1835 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1836 the number of input digits (it was and remains linear-time for bases
1837 2, 4, 8, 16 and 32).
1838
Tim Petersb713ec22006-05-23 18:45:30 +00001839- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1840 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1841 an integer close to ``sys.maxint``. This was repaired by patch
1842 #1335972, which also gives a nice speedup.
1843
Richard Jonescebbefc2006-05-23 18:28:17 +00001844- Patch #1337051: reduced size of frame objects.
1845
1846- PyErr_NewException now accepts a tuple of base classes as its
1847 "base" parameter.
1848
Richard Jones7c88dcc2006-05-23 10:37:38 +00001849- Patch #876206: function call speedup by retaining allocated frame
1850 objects.
1851
Georg Brandl7b90e162006-05-18 07:01:27 +00001852- Bug #1462152: file() now checks more thoroughly for invalid mode
1853 strings and removes a possible "U" before passing the mode to the
1854 C library function.
1855
Neal Norwitz1004a532006-05-15 07:17:23 +00001856- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1857
Neal Norwitz373f0a72006-05-15 07:04:36 +00001858- Bug #1487966: Fix SystemError with conditional expression in assignment
1859
Martin v. Löwis879768d2006-05-11 13:28:43 +00001860- WindowsError now has two error code attributes: errno, which carries
1861 the error values from errno.h, and winerror, which carries the error
1862 values from winerror.h. Previous versions put the winerror.h values
1863 (from GetLastError()) into the errno attribute.
1864
Martin v. Löwis77736712006-05-04 05:51:03 +00001865- Patch #1475845: Raise IndentationError for unexpected indent.
1866
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001867- Patch #1479181: split open() and file() from being aliases for each other.
1868
Tim Peters44bd9862006-06-01 13:49:23 +00001869- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1870 methods were always silently ignored by dictionaries when comparing keys.
1871 They are now passed through (except when using the C API function
1872 ``PyDict_GetItem()``, whose semantics did not change).
1873
1874- Bug #1456209: In some obscure cases it was possible for a class with a
1875 custom ``__eq__()`` method to confuse dict internals when class instances
1876 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1877 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001879Extension Modules
1880-----------------
1881
Trent Mick960a3f82006-06-28 20:30:41 +00001882- Bug #1295808: expat symbols should be namespaced in pyexpat
1883
1884- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1885
Brett Cannon6ee7d012006-06-08 16:23:04 +00001886- Change binascii.hexlify to accept a read-only buffer instead of only a char
1887 buffer and actually follow its documentation.
1888
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001889- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1890
Nick Coghlanc649ec52006-05-29 12:43:05 +00001891- Patch #1478788 (modified version): The functional extension module has
1892 been renamed to _functools and a functools Python wrapper module added.
1893 This provides a home for additional function related utilities that are
1894 not specifically about functional programming. See PEP 309.
1895
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001896- Patch #1493701: performance enhancements for struct module.
1897
Georg Brandl378d5922006-05-17 14:26:50 +00001898- Patch #1490224: time.altzone is now set correctly on Cygwin.
1899
Georg Brandl8d3342b2006-05-16 07:38:27 +00001900- Patch #1435422: zlib's compress and decompress objects now have a
1901 copy() method.
1902
Andrew MacIntyre92913322006-06-13 15:04:24 +00001903- Patch #1454481: thread stack size is now tunable at runtime for thread
1904 enabled builds on Windows and systems with Posix threads support.
1905
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001906- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1907 (up to the system limit of 32K characters).
1908
1909- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1910 As a result, these functions now raise WindowsError instead of OSError.
1911
Tim Peters7a822da2006-05-25 21:50:17 +00001912- ``time.clock()`` on Win64 should use the high-performance Windows
1913 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1914 Windows platforms).
1915
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001916- Calling Tk_Init twice is refused if the first call failed as that
1917 may deadlock.
1918
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001919- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1920 accept it without potentially using an uninitialized pointer.
1921
1922- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1923 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1924 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001925
Gregory P. Smith372b5832006-06-05 18:48:21 +00001926- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001927 [pybsddb project SF patch number 1466734]
1928
Gregory P. Smith372b5832006-06-05 18:48:21 +00001929- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1930 parameter is supplied. [SF pybsddb bug #1477863]
1931
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001932- bsddb: the __len__ method of a DB object has been fixed to return correct
1933 results. It could previously incorrectly return 0 in some cases.
1934 Fixes SF bug 1493322 (pybsddb bug 1184012).
1935
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001936- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1937 aborts the db transaction safely when a modifier callback fails.
1938 Fixes SF python patch/bug #1408584.
1939
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001940- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001941 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001942 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1943 database calls that would previously deadlock. [SF python bug #775414]
1944
Vinay Sajip28e57612006-07-01 10:45:20 +00001945- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001946
Walter Dörwald4994d952006-06-19 08:07:50 +00001947- Patch #1506645: add Python wrappers for the curses functions
1948 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001949

1951-------
1952
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001953- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1954 functions.
1955
Martin v. Löwis3798da02006-06-17 18:44:27 +00001956- Patch #812986: Update turtle output even if not tracing.
1957
Vinay Sajip28e57612006-07-01 10:45:20 +00001958- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001959 Tkinter.BaseWidget.
1960
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001961- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1962
Martin v. Löwis337487e2006-06-17 09:15:14 +00001963- Patch #763580: Add name and value arguments to Tkinter variable
1964 classes.
1965
Georg Brandl83cc0d02006-06-14 08:50:03 +00001966- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1967 mime.types file for determining MIME types.
1968
Georg Brandl2605ca82006-06-14 06:08:31 +00001969- Bug #1339007: Shelf objects now don't raise an exception in their
1970 __del__ method when initialization failed.
1971
Martin v. Löwisd8251432006-06-14 05:21:04 +00001972- Patch #1455898: The MBCS codec now supports the incremental mode for
1973 double-byte encodings.
1974
Tim Peters43898b42006-06-14 04:09:25 +00001975- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1976 guarantee that adjacent triples in the return list always describe
1977 non-adjacent blocks. Previously, a pair of matching blocks could end
1978 up being described by multiple adjacent triples that formed a partition
1979 of the matching pair.
1980
Greg Ward0e0c9f42006-06-11 16:24:11 +00001981- Bug #1498146: fix optparse to handle Unicode strings in option help,
1982 description, and epilog.
1983
Greg Wardd1c797e2006-06-11 14:42:41 +00001984- Bug #1366250: minor optparse documentation error.
1985
Greg Ward7f547402006-06-11 00:40:49 +00001986- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1987 clarify docs.
1988
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001989- The wsgiref package has been added to the standard library.
1990
Nick Coghlan676725d2006-06-08 13:54:49 +00001991- The functions update_wrapper() and wraps() have been added to the functools
1992 module. These make it easier to copy relevant metadata from the original
1993 function when writing wrapper functions.
1994
Tim Petersd6a9eef2006-06-05 01:48:21 +00001995- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1996 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001997
Martin v. Löwis3f767792006-06-04 19:36:28 +00001998- Patch #1359618: Speed up charmap encoder by using a trie structure
1999 for lookup.
2000
Tim Petersd609b1a2006-06-02 23:22:51 +00002001- The functions in the ``pprint`` module now sort dictionaries by key
2002 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2003 if and only if its display required more than one line, although that
2004 wasn't documented. The new behavior increases predictability; e.g.,
2005 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2006
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002007- Patch #1497027: try HTTP digest auth before basic auth in urllib2
2008 (thanks for J. J. Lee).
2009
Georg Brandl2b330372006-05-28 20:23:12 +00002010- Patch #1496206: improve urllib2 handling of passwords with respect to
2011 default HTTP and HTTPS ports.
2012
George Yoshidaf3c65de2006-05-28 16:39:09 +00002013- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
2014
Bob Ippolito7298f272006-05-23 18:43:47 +00002015- Patch #1281707: speed up gzip.readline.
2016
Georg Brandlb89316f2006-05-17 15:51:16 +00002017- Patch #1180296: Two new functions were added to the locale module:
2018 format_string() to get the effect of "format % items" but locale-aware,

2026
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002027- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2028 stdout arguments, making it possible to redirect input and output
2029 for remote debugging.
2030
2031- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2032 a couple of issues, notably handling of long file names using the
2033 GNU LONGNAME extension.
2034
2035- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2036 new flag when ``name`` is already the name of an option flag.
2037
2038- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002077What's New in Python 2.5 alpha 2?
2078=================================
2079
2080*Release date: 27-APR-2006*
2081
2082Core and builtins
2083-----------------
2084
Thomas Heller1b046642006-04-18 18:51:06 +00002085- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2086 by converting these apis from macros into exported functions again:
2087
2088 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2089 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2090 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2091 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2092 PyRun_String Py_CompileString
2093
Martin v. Löwis45294a92006-04-18 06:24:08 +00002094- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2095
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002096- All uses of PyStructSequence_InitType have been changed to initialize
2097 the type objects only once, even if the interpreter is initialized
2098 multiple times.
2099
Neal Norwitz61546162006-04-14 05:20:28 +00002100- Bug #1454485, array.array('u') could crash the interpreter. This was
2101 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2102 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2103
2104- Py_UNICODE is unsigned. It was always documented as unsigned, but
2105 due to a bug had a signed value in previous versions.
2106
Tim Peters3a5e8b12006-04-11 01:44:07 +00002107- Patch #837242: ``id()`` of any Python object always gives a positive
2108 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2109 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002110 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002111 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002112
Tim Peters3a5e8b12006-04-11 01:44:07 +00002113 def __hash__(self):
2114 return id(self) # WRONG
2115
2116 because a hash result must be a (short) Python int but it was always
2117 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002118 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002119 was always usable as a hash value before this patch. That's no longer
2120 necessarily so.
2121
2122- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002123 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002124 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002125 #1454844)
2126
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002127- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2128 involving generators that have paused outside of any ``try`` or ``with``
2129 blocks. (In 2.5a1, a paused generator that was part of a reference
2130 cycle could not be garbage collected, regardless of whether it was
2131 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00002132
Anthony Baxter51bcb682006-04-05 14:51:42 +00002133Extension Modules
2134-----------------
2135
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00002136- Patch #1191065: Fix preprocessor problems on systems where recvfrom
2137 is a macro.
2138
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002139- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2140 fails with an error condition.
2141
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002142- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2143
2144- Bug #1117761: bsddb.*open() no longer raises an exception when using
2145 the cachesize parameter.
2146
2147- Bug #1149413: bsddb.*open() no longer raises an exception when using
2148 a temporary db (file=None) with the 'n' flag to truncate on open.
2149
2150- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2151 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002152
Armin Rigoa9017c32006-04-19 11:50:27 +00002153- Patch #1062014: AF_UNIX sockets under Linux have a special
2154 abstract namespace that is now fully supported.
2155
Anthony Baxter51bcb682006-04-05 14:51:42 +00002156Library
2157-------
2158
Peter Astrand7d1d4362006-07-14 14:04:45 +00002159- Bug #1223937: subprocess.CalledProcessError reports the exit status
2160 of the process using the returncode attribute, instead of
2161 abusing errno.
2162
Tim Peters711bf302006-04-25 03:31:36 +00002163- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2164 a doctest to be skipped (the code is not run, and the expected output
2165 or exception is ignored).
2166
Nick Coghlanda2268f2006-04-24 04:37:15 +00002167- Fixed contextlib.nested to cope with exceptions being raised and
2168 caught inside exit handlers.
2169
Greg Wardab05edc2006-04-23 03:47:58 +00002170- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2171 hex, octal, or binary; add ``append_const`` action; keep going if
2172 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2173 added ``epilog`` for better help generation).
2174
Tim Peters21fbd572006-04-21 21:18:10 +00002175- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2176 called from a thread spawned as a side effect of importing a module.
2177
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002178- The pydoc module now supports documenting packages contained in
2179 .zip or .egg files.
2180
2181- The pkgutil module now has several new utility functions, such
2182 as ``walk_packages()`` to support working with packages that are either
2183 in the filesystem or zip files.
2184
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002185- The mailbox module can now modify and delete messages from
2186 mailboxes, in addition to simply reading them. Thanks to Gregory
2187 K. Johnson for writing the code, and to the 2005 Google Summer of
2188 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002189
Tim Petersc7605f22006-04-17 21:12:33 +00002190- The ``__del__`` method of class ``local`` in module ``_threading_local``
2191 returned before accomplishing any of its intended cleanup.
2192
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002193- Patch #790710: Add breakpoint command lists in pdb.
2194
Martin v. Löwis0db2a982006-04-16 20:55:38 +00002195- Patch #1063914: Add Tkinter.Misc.clipboard_get().
2196
Martin v. Löwis4b501e62006-04-15 08:41:11 +00002197- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
2198
Anthony Baxtere29002c2006-04-12 12:07:31 +00002199- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2200 Windows. Bug #1469163.
2201
Phillip J. Eby47032112006-04-11 01:07:43 +00002202- The warnings, linecache, inspect, traceback, site, and doctest modules
2203 were updated to work correctly with modules imported from zipfiles or
2204 via other PEP 302 __loader__ objects.
2205
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002206- Patch #1467770: Reduce usage of subprocess._active to processes which
2207 the application hasn't waited on.
2208
Martin v. Löwisb04dee92006-04-10 08:34:21 +00002209- Patch #1462222: Fix Tix.Grid.
2210
Neal Norwitza31bf182006-04-09 03:35:43 +00002211- Fix exception when doing glob.glob('anything*/')
2212
Skip Montanaro262fb922006-04-21 02:31:07 +00002213- The pstats.Stats class accepts an optional stream keyword argument to
2214 direct output to an alternate file-like object.
2215
Anthony Baxter51bcb682006-04-05 14:51:42 +00002216Build
2217-----
2218
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002219- The Makefile now has a reindent target, which runs reindent.py on
2220 the library.
2221
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002222- Patch #1470875: Building Python with MS Free Compiler
2223
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002224- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002225
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002226- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2227 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002228 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002229 CXX from --with-cxx-main, see description in README.
2230
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002231- Patch #1429775: Link extension modules with the shared libpython.
2232
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002233- Fixed a libffi build problem on MIPS systems.
2234
Tim Peters8931ff12006-05-13 23:28:20 +00002235- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2236 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2237 and "%zu" for unsigned integers of type ``size_t``.
2238
Anthony Baxter51bcb682006-04-05 14:51:42 +00002239Tests
2240-----
2241
Nick Coghlanda2268f2006-04-24 04:37:15 +00002242- test_contextlib now checks contextlib.nested can cope with exceptions
2243 being raised and caught inside exit handlers.
2244
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002245- test_cmd_line now checks operation of the -m and -c command switches
2246
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002247- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2248 it separately and by hand. It also wasn't cleaning up its changes to
2249 the current Decimal context.
2250
Thomas Woutersabd08882006-04-26 15:53:30 +00002251- regrtest.py now has a -M option to run tests that test the new limits of
2252 containers, on 64-bit architectures. Running these tests is only sensible
2253 on 64-bit machines with more than two gigabytes of memory. The argument
2254 passed is the maximum amount of memory for the tests to use.
2255
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00002256Tools

Anthony Baxter51bcb682006-04-05 14:51:42 +00002262Documentation
2263-------------
2264
Tim Petersb06d28c2006-05-12 01:57:59 +00002265- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2266
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002267- PEP 343: Added Context Types section to the library reference
2268 and attempted to bring other PEP 343 related documentation into
2269 line with the implementation and/or python-dev discussions.
2270
Tim Peters8dc73d22006-04-24 02:03:16 +00002271- Bug #1337990: clarified that ``doctest`` does not support examples
2272 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002275What's New in Python 2.5 alpha 1?
2276=================================
2277
Anthony Baxterebed3f62006-04-03 15:03:44 +00002278*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002279
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002280Core and builtins
2281-----------------
2282
Nick Coghlan43832302006-04-23 17:04:07 +00002283- PEP 338: -m command line switch now delegates to runpy.run_module
2284 allowing it to support modules in packages and zipfiles
2285
Martin v. Löwisc661b882006-04-20 04:54:23 +00002286- On Windows, .DLL is not an accepted file name extension for
2287 extension modules anymore; extensions are only found if they
2288 end in .PYD.
2289
Martin v. Löwisea62d252006-04-03 10:56:49 +00002290- Bug #1421664: sys.stderr.encoding is now set to the same value as
2291 sys.stdout.encoding.
2292
Neal Norwitz92e212f2006-04-03 04:48:37 +00002293- __import__ accepts keyword arguments.
2294
Georg Brandlccadf842006-03-31 18:54:53 +00002295- Patch #1460496: round() now accepts keyword arguments.
2296
Anthony Baxter262c00a2006-03-30 10:53:17 +00002297- Fixed bug #1459029 - unicode reprs were double-escaped.
2298
Hye-Shik Changd478f342006-03-23 12:32:36 +00002299- Patch #1396919: The system scope threads are reenabled on FreeBSD
2300 5.4 and later versions.
2301
Neal Norwitze98ccf62006-03-23 05:39:47 +00002302- Bug #1115379: Compiling a Unicode string with an encoding declaration
2303 now gives a SyntaxError.
2304
Georg Brandlabd1ff82006-03-18 07:59:59 +00002305- Previously, Python code had no easy way to access the contents of a
2306 cell object. Now, a ``cell_contents`` attribute has been added
2307 (closes patch #1170323).
2308
Tim Peterscf79aac2006-03-16 01:14:46 +00002309- Patch #1123430: Python's small-object allocator now returns an arena to
2310 the system ``free()`` when all memory within an arena becomes unused
2311 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2312 freed. Some applications will see a drop in virtual memory size now,
2313 especially long-running applications that, from time to time, temporarily
2314 use a large number of small objects. Note that when Python returns an
2315 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002316 platform C library will in turn return that memory to the operating system.
2317 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002318 appears to be effective at least on Microsoft C and gcc-based systems.
2319 Thanks to Evan Jones for hard work and patience.
2320
Georg Brandl533ff6f2006-03-08 18:09:27 +00002321- Patch #1434038: property() now uses the getter's docstring if there is
2322 no "doc" argument given. This makes it possible to legitimately use
2323 property() as a decorator to produce a read-only property.
2324
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002325- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2326 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2327 of requiring an int or long in slicing and a few other contexts, enabling
2328 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2329
Neal Norwitz995acdf2006-03-07 05:01:00 +00002330- Fixed various bugs reported by Coverity's Prevent tool.
2331
Brett Cannonbf364092006-03-01 04:25:17 +00002332- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2333 new exception base class, BaseException, which has a new message attribute.
2334 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2335 Raising a string exception now raises a DeprecationWarning.
2336
Thomas Woutersfb609f42006-02-28 16:37:25 +00002337- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2338 explicitly relative, using 'from .module import name' to mean 'from the same
2339 package as this module is in. Imports without dots still default to the
2340 old relative-then-absolute, unless 'from __future__ import
2341 absolute_import' is used.
2342
Brett Cannona7446e32006-02-27 23:39:10 +00002343- Properly check if 'warnings' raises an exception (usually when a filter set
2344 to "error" is triggered) when raising a warning for raising string
2345 exceptions.
2346
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002347- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002348 The name was removed from Include/code.h.
2349
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002350- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002351
Guido van Rossum1968ad32006-02-25 22:38:04 +00002352- Patch 1433928:
2353 - The copy module now "copies" function objects (as atomic objects).
2354 - dict.__getitem__ now looks for a __missing__ hook before raising
2355 KeyError.
2356
Tim Peters84ef21c2006-02-28 20:39:06 +00002357- PEP 343: with statement implemented. Needs ``from __future__ import
2358 with_statement``. Use of 'with' as a variable will generate a warning.
2359 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002360 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002361 The following objects have __context__ methods:
2362 - The built-in file type.
2363 - The thread.LockType type.
2364 - The following types defined by the threading module:
2365 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2366 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002367
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002368- Fix the encodings package codec search function to only search
2369 inside its own package. Fixes problem reported in patch #1433198.
2370
2371 Note: Codec packages should implement and register their own
2372 codec search function. PEP 100 has the details.
2373
Tim Peters9ea89d22006-06-04 03:26:02 +00002374- PEP 353: Using ``Py_ssize_t`` as the index type.
2375
2376- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2377 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2378 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2379 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2380 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002381
Neal Norwitzfc76d632006-01-10 06:03:13 +00002382- Patch #1400181, fix unicode string formatting to not use the locale.
2383 This is how string objects work. u'%f' could use , instead of .
2384 for the decimal point. Now both strings and unicode always use periods.
2385
Neal Norwitz671b9e32006-01-09 07:07:12 +00002386- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2387 configure would break checking curses.h.
2388
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002389- Bug #959576: The pwd module is now builtin. This allows Python to be
2390 built on UNIX platforms without $HOME set.
2391
Neal Norwitzc10978f2005-12-19 06:07:16 +00002392- Bug #1072182, fix some potential problems if characters are signed.
2393
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002394- Bug #889500, fix line number on SyntaxWarning for global declarations.
2395
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002396- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2397
Neal Norwitze7214a12005-12-18 05:03:17 +00002398- Support for converting hex strings to floats no longer works.
2399 This was not portable. float('0x3') now raises a ValueError.
2400
Barry Warsaw2a38a862005-12-18 01:27:35 +00002401- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002402 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002403 is now displayed in interactive prompt banner.
2404
Georg Brandlfa166682005-12-17 21:45:17 +00002405- Implementation of PEP 341 - Unification of try/except and try/finally.
2406 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002407 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002408
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002409- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2410 now encodes backslash correctly.
2411
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002412- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2413
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002414- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002415 and long longs.
2416
Neal Norwitz67715f02005-11-09 06:59:35 +00002417- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002418 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002419 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002420
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002421- Replaced most Unicode charmap codecs with new ones using the
2422 new Unicode translate string feature in the builtin charmap
2423 codec; the codecs were created from the mapping tables available
2424 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2425 encodings now include a mapping for the Apple logo)
2426
Tim Peterse3547fd2005-12-16 23:13:57 +00002427- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002428
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002429- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002430
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002431- A new AST parser implementation was completed. The abstract
2432 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002433 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002434
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002435- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002436 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2437
Neal Norwitz708e51a2005-10-03 04:48:15 +00002438- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2439
Neal Norwitz11bd1192005-10-03 00:54:56 +00002440- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2441 Provide a warning when a directory is passed on the command line.
2442
Neal Norwitz40d37812005-10-02 01:48:49 +00002443- Fix segfault with invalid coding.
2444
2445- SF bug #772896: unknown encoding results in MemoryError.
2446
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002447- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002448 supported a __len__() method which evaluated to False when the iterator
2449 was empty.
2450
Guido van Rossum630db602005-09-20 18:49:54 +00002451- On 64-bit platforms, when __len__() returns a value that cannot be
2452 represented as a C int, raise OverflowError.
2453
Skip Montanarof8948ca2005-09-19 03:54:46 +00002454- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002455 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002456
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002457- SF bug #893549: parsing keyword arguments was broken with a few format
2458 codes.
2459
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002460- Changes donated by Elemental Security to make it work on AIX 5.3
2461 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2462 bug #105470: test_pwd fails on 64bit system (Opteron).
2463
Guido van Rossum539c6622005-09-14 17:49:54 +00002464- Changes donated by Elemental Security to make it work on HP-UX 11 on
2465 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2466
Georg Brandl4550b8d2005-08-26 06:43:52 +00002467- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002468 (fixes bug #1119418).
2469
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002470- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2471
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002472- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2473 exceptions that cause a function to exit.
2474
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002475- The implementation of set() and frozenset() was revised to use its
2476 own internal data structure. Memory consumption is reduced by 1/3
2477 and there are modest speed-ups as well. The API is unchanged.
2478
Tim Petersde7990b2005-07-17 23:45:23 +00002479- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2480
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002481- SF bug #1229429: PyObject_CallMethod failed to decrement some
2482 reference counts in some error exit cases.
2483
Tim Petersecc6e6a2005-07-10 22:30:55 +00002484- SF bug #1185883: Python's small-object memory allocator took over
2485 a block managed by the platform C library whenever a realloc specified
2486 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002487 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002488 portable way to copy data from the C-managed block into Python's
2489 small-object space without risking a memory fault. Python's small-object
2490 realloc now leaves such blocks under the control of the platform C
2491 realloc.
2492
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002493- SF bug #1232517: An overflow error was not detected properly when
2494 attempting to convert a large float to an int in os.utime().
2495
Raymond Hettinger3296e692005-06-29 23:29:56 +00002496- SF bug #1224347: hex longs now print with lowercase letters just
2497 like their int counterparts.
2498
Michael W. Hudson188d4362005-06-20 16:52:57 +00002499- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2500 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2501 interpreter states; back out that fix and do a better job (see
2502 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2503 for a longer write-up of the problem).
2504
Michael W. Hudsondf888462005-06-03 14:41:55 +00002505- SF patch #1180995: marshal now uses a binary format by default when
2506 serializing floats.
2507
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002508- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2509 the routines that promise to produce IEEE 754 binary representations
2510 of floats now simply copy bytes around.
2511
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002512- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2513 278.
2514
Brett Cannonc3647ac2005-04-26 03:45:26 +00002515- patch #1109424: int, long, float, complex, and unicode now check for the
2516 proper magic slot for type conversions when subclassed. Previously the
2517 magic slot was ignored during conversion. Semantics now match the way
2518 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002519 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002520 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002521 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002522
Barry Warsawc8d907c2005-04-19 23:43:40 +00002523- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2524 NULL, now raise an AttributeError when attempting to set or delete the
2525 attribute. Previously a TypeError was raised, but this was inconsistent
2526 with the equivalent pure-Python implementation.
2527
Michael W. Hudson774479c2005-04-18 08:46:17 +00002528- It is now safe to call PyGILState_Release() before
2529 PyEval_InitThreads() (note that if there is reason to believe there
2530 are multiple threads around you still must call PyEval_InitThreads()
2531 before using the Python API; this fix is for extension modules that
2532 have no way of knowing if Python is multi-threaded yet).
2533
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002534- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2535 disabled caused a crash.
2536
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002537- Bug #1165306: instancemethod_new allowed the creation of a method
2538 with im_class == im_self == NULL, which caused a crash when called.
2539
Tim Petersecc6e6a2005-07-10 22:30:55 +00002540- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002541 fixes the crash seen in bug #1165761
2542
Raymond Hettinger96229b12005-03-11 06:49:40 +00002543- Added two new builtins, any() and all().
2544
Brett Cannon409d8f22005-03-05 06:47:57 +00002545- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002546 (e.g., ``class C(): pass`` is no longer a syntax error).
2547 Patch #1176012 added support to the 'parser' module and 'compiler' package
2548 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002549
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002550- Patch #1115086: Support PY_LONGLONG in structmember.
2551
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002552- Bug #1155938: new style classes did not check that __init__() was
2553 returning None.
2554
Tim Petersecc6e6a2005-07-10 22:30:55 +00002555- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002556 ('\') with a specific error message.
2557
Martin v. Löwisff232d72005-03-03 09:24:38 +00002558- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2559
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002560- Bug #1124295: the __name__ attribute of file objects was
2561 inadvertently made inaccessible in restricted mode.
2562
Tim Petersecc6e6a2005-07-10 22:30:55 +00002563- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002564 an ferror() call.
2565
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002566- min() and max() now support key= arguments with the same meaning as in
2567 list.sort().
2568
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002569- The peephole optimizer now performs simple constant folding in expressions:
2570 (2+3) --> (5).
2571
Raymond Hettingera422c342005-01-11 03:03:27 +00002572- set and frozenset objects can now be marshalled. SF #1098985.
2573
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002574- Bug #1077106: Poor argument checking could cause memory corruption
2575 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002576
Jeremy Hyltonab630502005-02-04 18:44:06 +00002577- The parser did not complain about future statements in illegal
2578 positions. It once again reports a syntax error if a future
2579 statement occurs after anything other than a doc string.
2580
Neil Schemenauercf52c072005-08-12 17:34:58 +00002581- Change the %s format specifier for str objects so that it returns a
2582 unicode instance if the argument is not an instance of basestring and
2583 calling __str__ on the argument returns a unicode instance.
2584
Tim Petersf4e69282006-02-27 17:15:31 +00002585- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2586 current thread state when the auto-GIL-state machinery knows about
2587 it (since the thread state is being deleted, continuing to remember it
2588 can't help, but can hurt if another thread happens to get created with
2589 the same thread id).

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002784
Nick Coghlan43832302006-04-23 17:04:07 +00002785- PEP 338: new module runpy defines a run_module function to support
2786 executing modules which provide access to source code or a code object
2787 via the PEP 302 import mechanisms.
2788

2797 in attribute values.
2798
Anthony Baxterc51ee692006-04-01 00:57:31 +00002799- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002800 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002801 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002802 module will not be built.
2803
Tim Petersc17976e2006-04-01 00:26:53 +00002804- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2805 aren't officially supported here, and trying to use them will probably
2806 raise an exception some day. But dicts have been allowed, and "mostly
2807 worked", so support for them won't go away without warning.
2808
Georg Brandl338ef7d2006-03-31 18:42:16 +00002809- Bug #1445068: getpass.getpass() can now be given an explicit stream
2810 argument to specify where to write the prompt.
2811
Georg Brandl22ec80b2006-03-31 18:25:44 +00002812- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2827
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002828- email 4.0 package now integrated. This is largely the same as the email 3.0
2829 package that was included in Python 2.3, except that PEP 8 module names are
2830 now used (e.g. mail.message instead of email.Message). The MIME classes
2831 have been moved to a subpackage (e.g. email.mime.text instead of
2832 email.MIMEText). The old names are still supported for now. Several
2833 deprecated Message methods have been removed and lots of bugs have been
2834 fixed. More details can be found in the email package documentation.
2835
Walter Dörwald40108c92006-03-27 08:15:44 +00002836- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2837 (a subclass of tuple) that provides incremental decoders and encoders
2838 (a way to use stateful codecs without the stream API). Python functions
2839 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2840 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2841 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002842
Walter Dörwald067db482006-03-15 22:17:27 +00002843- Patch #1359365: Calling next() on a closed StringIO.String object raises
2844 a ValueError instead of a StopIteration now (like file and cString.String do).
2845 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2846 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002847
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002848- A regrtest option -w was added to re-run failed tests in verbose mode.

2854 grew an optional 'generation' argument.
2855
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00002856- A library msilib to generate Windows Installer files, and a distutils

2927 is that SHA-256 is a good choice for the time being, but
2928 that research should continue, and other alternatives may
2929 arise from this research. The larger SHA's also seem OK."

Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003114 + Dialect parameter parsing has been re-implemented to improve error
3115 reporting.
3116 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3117 dictates.
3118 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003119 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003120 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003121 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3122 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003123 + reader now allows \r characters to be quoted (previously it only allowed
3124 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003125 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003126 + Dialect classes passed to the module are no longer instantiated by
3127 the module before being parsed (the former validation scheme required
3128 this, but the mechanism was unreliable).
3129 + The dialect registry now contains instances of the internal
3130 C-coded dialect type, rather than references to python objects.
3131 + the internal c-coded dialect type is now immutable.
3132 + register_dialect now accepts the same keyword dialect specifications
3133 as the reader and writer, allowing the user to register dialects
3134 without first creating a dialect class.
3135 + a configurable limit to the size of parsed fields has been added -
3136 previously, an unmatched quote character could result in the entire
3137 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003138 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003139 the parser field size limit (returning the former limit). The initial
3140 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003141 + A line_num attribute has been added to the reader object, which tracks
3142 the number of lines read from the source iterator. This is not
3143 the same as the number of records returned, as records can span
3144 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003145 + reader and writer objects were not being registered with the cyclic-GC.
3146 This has been fixed.
3147
Brett Cannone6539c42005-01-08 02:43:53 +00003148- _DummyThread objects in the threading module now delete self.__block that is
3149 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3150 lock primitives tend to be limited in number and thus should not be wasted on
3151 a _DummyThread object. Fixes bug #1089632.
3152
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003153- The imghdr module now detects Exif files.
3154
Raymond Hettinger6065d322004-12-20 23:51:53 +00003155- StringIO.truncate() now correctly adjusts the size attribute.
3156 (Bug #951915).
3157
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003158- locale.py now uses an updated locale alias table (built using
3159 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3160 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003161 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003162
Raymond Hettinger3557f422004-12-07 12:02:02 +00003163- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3164
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003165- the pickle module no longer accepts the deprecated None option in the
3166 args tuple returned by __reduce__().
3167
Brett Cannon84667c02004-12-07 03:25:18 +00003168- optparse now optionally imports gettext. This allows its use in setup.py.
3169
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003170- the pickle module no longer uses the deprecated bin parameter.
3171
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003172- the shelve module no longer uses the deprecated binary parameter.
3173
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003174- the pstats module no longer uses the deprecated ignore() method.
3175
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003176- the filecmp module no longer uses the deprecated use_statcache argument.
3177
Raymond Hettinger664347b2004-12-04 21:21:53 +00003178- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3179 extended or overridden by subclasses. Formerly, the subclassed method would
3180 be ignored by the rest of the module. (Bug #1078905).
3181
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003182- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003183 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003184
Walter Dörwald36733692004-12-22 12:50:50 +00003185- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3186 once when a size argument is given. This prevents a buffer overflow in the
3187 tokenizer with very long source lines.
3188
Barry Warsaw538561e2006-01-01 21:48:54 +00003189- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3190 immediately after creating the object, without any intervening
3191 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003192
Skip Montanaro05885812005-01-16 20:48:27 +00003193- The reconvert.quote function can now emit triple-quoted strings. The
3194 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003195
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003196- ``UserString.MutableString`` now supports negative indices in
3197 ``__setitem__`` and ``__delitem__``
3198
Greg Ward40407942005-03-05 02:53:17 +00003199- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3200 correctly.
3201
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003202- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3203 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3204 character even if the user has passed a size parameter to get a proper
3205 line ending. Remove the special handling of a "\r\n" that has been split
3206 between two lines.
3207
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003208- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3209 about illegal code points. The codec now supports PEP 293 style error
3210 handlers.
3211
Walter Dörwald78a78b02005-09-01 12:04:29 +00003212- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003213 from the input stream, so that the output is a byte string in the correct
3214 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003215
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003216- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3217 considering it exactly like a '*'.
3218
Walter Dörwald007f8df2005-10-09 19:42:27 +00003219- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3220 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003221
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003222- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3223
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003224- Patch #1413711: Certain patterns of differences were making difflib
3225 touch the recursion limit.
3226
Walter Dörwald58917a62006-03-31 15:26:22 +00003227- Bug #947906: An object oriented interface has been added to the calendar
3228 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003229 called as a script (e.g. via ``python -mcalendar``). Localized month and
3230 weekday names can be ouput (even if an exotic encoding is used) using
3231 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003232
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003233Build
3234-----
3235
Neal Norwitz602d3392006-03-31 08:21:40 +00003236- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3237 by using -mieee gcc option.
3238
Martin v. Löwis86d66262006-02-17 08:40:11 +00003239- Patch #1432345: Make python compile on DragonFly.
3240
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003241- Build support for Win64-AMD64 was added.
3242
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003243- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3244
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003245- Patch #881820: look for openpty and forkpty also in libbsd.
3246
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003247- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3248 The zlib module is now builtin on Windows.
3249
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003250- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3251
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003252- Bug #1189330: configure did not correctly determine the necessary
3253 value of LINKCC if python was built with GCC 4.0.
3254
Trent Mick8321b422005-07-26 02:29:21 +00003255- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3256 vulnerability in zlib 1.2.1 and 1.2.2.
3257
Brett Cannon08cd5982005-04-24 22:26:38 +00003258- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3259 flags that change binary compatibility. Changes were also made to
3260 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003261 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003262
Bob Ippolitoed233462005-03-29 13:47:59 +00003263- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3264 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3265 no longer exists). This configure patch makes things right.
3266
Martin v. Löwise2713be2005-03-08 15:03:08 +00003267- Bug #1158607: Build with --disable-unicode again.
3268
Brett Cannon46d96232005-02-16 00:07:19 +00003269- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3270 defined. Discovered as a result of not being able to build on OS X.
3271
Brett Cannon516592f2004-12-07 00:42:59 +00003272- setup.py now uses the directories specified in LDFLAGS using the -L option
3273 and in CPPFLAGS using the -I option for adding library and include
3274 directories, respectively, for compiling extension modules against. This has
3275 led to the core being compiled using the values in CPPFLAGS. It also removes
3276 the need for the special-casing of both DarwinPorts and Fink for darwin since
3277 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3278 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3279 Fink, ``-I/opt/local/include`` for DarwinPorts).
3280
Brett Cannon43802422005-02-10 20:48:03 +00003281- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3282 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3283 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3284 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003286C API
3287-----
3288
Tim Petersc9d78aa2006-03-26 23:27:58 +00003289- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3290 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3291 is obtained via the ``PyObject_`` family, it must be released via the
3292 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3293 always been officially true, but when Python's small-object allocator was
3294 introduced, an attempt was made to cater to a few extension modules
3295 discovered at the time that obtained memory via ``PyObject_New`` but
3296 released it via ``PyMem_DEL``. It's years later, and if such code still
3297 exists it will fail now (probably with segfaults, but calling wrong
3298 low-level memory management functions can yield many symptoms).
3299
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003300- Added a C API for set and frozenset objects.
3301
Raymond Hettinger66517482004-12-03 11:45:13 +00003302- Removed PyRange_New().
3303
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003304- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3305 mapping argument now. This string is used as a mapping table. Byte values
3306 greater than the length of the string and 0xFFFE are treated as undefined
3307 mappings.
