Nick Coghlanbb0996c2006-09-03 01:20:46 +00007What's New in Python 2.6 alpha 1?
8=================================
Martin v. Löwis2eb8c4f2006-08-18 03:47:18 +00009
Guido van Rossum901464f2007-12-08 04:38:23 +000010*Release date: XX-XXX-2008*
Neal Norwitz92422fb2006-08-18 03:57:54 +000011
12Core and builtins
13-----------------
14
Christian Heimesc94e2b52008-01-14 04:13:37 +000015- sys.float_info / PyFloat_GetInfo: The floating point information
16 object was converted from a dict to a specialized structseq object.
17
Christian Heimesf31b69f2008-01-14 03:42:48 +000018- Patch #1816: Added sys.flags structseq. It exposes the status of most
19 command line arguments and PYTHON* environment variables.
20
21- Object/structseq.c: Implemented new structseq representation. The patch
22 makes structseqs (e.g. the return value of os.stat) more readable.
Christian Heimes9c201962008-01-14 03:33:52 +000023
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +000024- Patch #1700288: added a type attribute cache that caches method accesses,
25 resulting in speedups in heavily object-oriented code.
26
Neal Norwitz3fc15b82008-01-10 05:42:58 +000027- Bug #1776: __import__() no longer accepts filenames on any platform.
28 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +000029
Georg Brandlaed6c662008-01-07 17:25:53 +000030- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
31
Georg Brandl2da0fce2008-01-07 17:09:35 +000032- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE envvar
33 and sys.dont_write_bytecode attribute. All these can be set to forbid Python
34 to attempt to write compiled bytecode files.
35
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +000036- Improve some exception messages when Windows fails to load an extension
37 module. Now we get for example '%1 is not a valid Win32 application' instead
38 of 'error code 193'.
39
Christian Heimes8267d1d2008-01-04 00:37:34 +000040- Bug #1481296: Fixed long(float('nan'))!=0L.
41
Christian Heimeseebb79c2008-01-03 22:32:26 +000042- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x, y)
43 functions.
Christian Heimese2ca4242008-01-03 20:23:15 +000044
Christian Heimes0a8143f2007-12-18 23:22:54 +000045- Issue #1635: Platform independent creation and representation of NaN
46 and INF. float("nan"), float("inf") and float("-inf") now work on every
47 platform with IEEE 754 semantics.
48
Raymond Hettingerfd7ed402007-12-18 21:24:09 +000049- Compiler now generates simpler and faster code for dictionary literals.
50 The oparg for BUILD_MAP now indicates an estimated dictionary size.
51 There is a new opcode, STORE_MAP, for adding entries to the dictionary.
52
Christian Heimesdb3d6cb2007-12-16 21:39:43 +000053- Issue #1638: %zd configure test fails on Linux
54
Christian Heimes90e10e72007-12-14 02:35:23 +000055- Issue #1620: New property decorator syntax was modifying the decorator
56 in place instead of creating a new decorator object.
57
Christian Heimes284d9272007-12-10 22:28:56 +000058- Issue #1580: New free format floating point representation based on
59 "Floating-Point Printer Sample Code", by Robert G. Burger. For example
60 repr(11./5) now returns '2.2' instead of '2.2000000000000002'.
61
Skip Montanaro26015492007-12-08 15:33:24 +000062- Issue #1538: Avoid copying string in split/rsplit if the split
63 char is not found.
64
Andrew M. Kuchling395fe442007-12-05 13:27:20 +000065- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +000066 SystemError.
67
Nick Coghlanef01d822007-12-03 12:55:17 +000068- PEP 366: Allow explicit relative imports when executing modules
69 inside packages with the -m switch via a new module level
70 __package__ attribute.
71
Christian Heimesdfdfaab2007-12-01 11:20:10 +000072- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
73 ``PyFloat_GetInfo()`` to the float API.
74
Amaury Forgeot d'Arcdafd32b2007-11-30 20:51:40 +000075- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
76 format code incorrectly truncated the length to an int, even when
77 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
78 results with huge strings.
79
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +000080- Issue #1402: Fix a crash on exit, when another thread is still running, and
81 if the deallocation of its frames somehow calls the PyGILState_Ensure() /
82 PyGILState_Release() functions.
83
Christian Heimes28104c52007-11-27 23:16:44 +000084- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
85
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +000086- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
87 attribute of an empty cell object.
88
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +000089- Issue #1460: The utf-7 incremental decoder did not accept truncated input.
90 It now correctly saves its state between chunks of data.
91
Nick Coghlan327a39b2007-11-18 11:56:28 +000092- Patch #1739468: Directories and zipfiles containing a __main__.py file can
93 now be directly executed by passing their name to the interpreter. The
94 directory/zipfile is automatically inserted as the first entry in sys.path.
95
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +000096- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
97 generator expression when at the same time the executed code is closing a
98 paused generator.
99
Raymond Hettinger1760c8a2007-11-08 02:52:43 +0000100- sets and frozensets now have an isdisjoint() method.
101
Raymond Hettinger3f8caa32007-10-24 01:28:33 +0000102- optimize the performance of builtin.sum().
103
Neal Norwitz44f326e2007-10-05 05:29:17 +0000104- Fix warnings found by the new version of the Coverity checker.
105
Raymond Hettinger8f669372007-10-03 21:18:11 +0000106- The enumerate() builtin function is no longer bounded to sequences smaller
107 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
108 shifts from ints to longs.
109
Brett Cannon0b14f242007-09-30 19:45:10 +0000110- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
111 having a self-referential tuple, which is possible from C code. Nor did
112 object's tp_str consider that a type's tp_str could do something that could
113 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
114 respectively, fixed the issues.
115
Brett Cannon01531592007-09-17 03:28:34 +0000116- Issue #1164: It was possible to trigger deadlock when using the 'print'
117 statement to write to a file since the GIL was not released as needed. Now
118 PyObject_Print() does the right thing along with various tp_print
119 implementations of the built-in types and those in the collections module.
120
Brett Cannon4c20bc42007-09-11 21:02:28 +0000121- Issue #1147: Exceptions were directly allowing string exceptions in their
122 throw() method even though string exceptions no longer allowed.
123
Brett Cannona0c05512007-09-10 21:38:27 +0000124- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
125 list by using the recursion counter.
126
Brett Cannon1e534b52007-09-07 04:18:30 +0000127- Issue #1202533: Fix infinite recursion calls triggered by calls to
128 PyObject_Call() never calling back out to Python code to trigger recursion
129 depth updates/checks. Required the creation of a static RuntimeError
130 instance in case normalizing an exception put the recursion check value past
131 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
132
Martin v. Löwisa5136192007-09-04 14:19:28 +0000133- Patch #1031213: Decode source line in SyntaxErrors back to its original source
134 encoding.
135
Neal Norwitz766d8802007-08-03 06:46:29 +0000136- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
137

139 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
140 PyVarObject_HEAD_INIT.
141
Georg Brandl7c3b50d2007-07-12 08:38:00 +0000142- Patch #1673759: add a missing overflow check when formatting floats
143 with %G.
144
Martin v. Löwis6371cd82007-06-09 07:42:52 +0000145- Patch #1733960: Allow T_LONGLONG to accept ints.
146
Walter Dörwald84a3efe2007-06-13 16:57:12 +0000147- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
148
Neal Norwitzdb2b1b32007-06-11 07:36:24 +0000149- Prevent expandtabs() on string and unicode objects from causing a segfault
150 when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +0000151
Martin v. Löwisda587ab2007-06-08 17:29:20 +0000152- Bug #1733488: Fix compilation of bufferobject.c on AIX.
153
Georg Brandl25497a12007-06-01 19:20:27 +0000154- Bug #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +0000155
Neal Norwitz0ac60192007-05-27 04:08:54 +0000156- Add new attribute names for function objects. All the func_* become
157 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
158
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +0000159- Add -3 option to the interpreter to warn about features that are
160 deprecated and will be changed/removed in Python 3.0.
161
Georg Brandl2134e752007-05-21 20:34:16 +0000162- Patch #1686487: you can now pass any mapping after '**' in function
163 calls.
164
Collin Winter62903052007-05-18 23:11:24 +0000165- except clauses may now be spelled either "except E, target:" or
166 "except E as target:". This is to provide forwards compatibility with
167 Python 3.0.
168
Brett Cannon229cee22007-05-05 01:34:02 +0000169- Deprecate BaseException.message as per PEP 352.
170
Armin Rigo9790a272007-05-02 19:23:31 +0000171- Bug #1303614: don't expose object's __dict__ when the dict is
172 inherited from a builtin base.
173
Vinay Sajip8549ce32007-05-06 17:53:37 +0000174- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +0000175 setting a plain string, ie don't expand to single letter identifiers.
176
Raymond Hettinger13936692007-04-11 18:40:58 +0000177- Request #1191699: Slices can now be pickled.
178
Raymond Hettinger4db5fe92007-04-12 04:10:00 +0000179- Request #1193128: str.translate() now allows a None argument for
180 translations that only remove characters without re-mapping the
181 remaining characters.
182
Georg Brandl5cb76c12007-03-21 09:00:39 +0000183- Patch #1682205: a TypeError while unpacking an iterable is no longer
184 masked by a generic one with the message "unpack non-sequence".
185
Neal Norwitzaa754b72007-03-21 06:39:48 +0000186- Remove unused file Python/fmod.c.
187
Guido van Rossum143b5642007-03-23 04:58:42 +0000188- Bug #1683368: The object.__init__() and object.__new__() methods are
189 now stricter in rejecting excess arguments. The only time when
190 either allows excess arguments is when it is not overridden and the
191 other one is. For backwards compatibility, when both are
192 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +0000193 warning later). Also, type.__init__() insists on the same signature
194 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +0000195
Georg Brandl2b869942007-03-17 16:08:45 +0000196- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
197 to complex using its __complex__() method before falling back to the
198 __float__() method. Therefore, the functions in the cmath module now
199 can operate on objects that define a __complex__() method.
200
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +0000201- Patch #1623563: allow __class__ assignment for classes with __slots__.
202 The old and the new class are still required to have the same slot names.
203
Collin Winter77c67bd2007-03-16 04:11:30 +0000204- Patch #1642547: Fix an error/crash when encountering syntax errors in
205 complex if statements.
206
Žiga Seilnacht20f43d32007-03-15 11:44:55 +0000207- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
208 is called with an object that is faking its type.
209
Žiga Seilnacht71436f02007-03-14 12:24:09 +0000210- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
211 name.
212
Georg Brandl5240d742007-03-13 20:46:32 +0000213- Patch #1444529: the builtin compile() now accepts keyword arguments.
214
Georg Brandl7b9c5552007-03-12 14:30:05 +0000215- Bug #1678647: write a newline after printing an exception in any
216 case, even when converting the value to a string failed.
217
Georg Brandl871f1bc2007-03-12 13:17:36 +0000218- The dir() function has been extended to call the __dir__() method on
219 its argument, if it exists. If not, it will work like before. This allows
220 customizing the output of dir() in the presence of a __getattr__().
221
Collin Winter276887b2007-03-12 16:11:39 +0000222- Patch #922167: Python no longer segfaults when faced with infinitely
223 self-recursive reload() calls (as reported by bug #742342).
224
Žiga Seilnacht89032082007-03-11 15:54:54 +0000225- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
226
Collin Wintere38051d2007-03-09 20:33:07 +0000227- Patch #1491866: change the complex() constructor to allow parthensized
228 forms. This means complex(repr(x)) now works instead of raising a
229 ValueError.
230
Georg Brandlaa2321b2007-03-07 00:40:28 +0000231- Patch #703779: unset __file__ in __main__ after running a file. This
232 makes the filenames the warning module prints much more sensible when
233 a PYTHONSTARTUP file is used.
234
Georg Brandl49aafc92007-03-07 00:34:46 +0000235- Variant of patch #697613: don't exit the interpreter on a SystemExit
236 exception if the -i command line option or PYTHONINSPECT environment
237 variable is given, but break into the interactive interpreter just like
238 on other exceptions or normal program exit.
239
Georg Brandl00cd8182007-03-06 18:41:12 +0000240- Patch #1638879: don't accept strings with embedded NUL bytes in long().
241
Georg Brandl098cd692007-03-06 12:17:50 +0000242- Bug #1674503: close the file opened by execfile() in an error condition.
243
Georg Brandl0fca97a2007-03-05 22:28:08 +0000244- Patch #1674228: when assigning a slice (old-style), check for the
245 sq_ass_slice instead of the sq_slice slot.
246
Neal Norwitz88516a62007-02-26 22:41:45 +0000247- When printing an unraisable error, don't print exceptions. before the name.
248 This duplicates the behavior whening normally printing exceptions.
249
Martin v. Löwisfd963262007-02-09 12:19:32 +0000250- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
251
Brett Cannon129bd522007-01-30 21:34:36 +0000252- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
253 catch a string exception raises DeprecationWarning.
254
Brett Cannonf5bee302007-01-23 23:21:22 +0000255- Bug #1377858: Fix the segfaulting of the interpreter when an object created
256 a weakref on itself during a __del__ call for new-style classes (classic
257 classes still have the bug).
258
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000259- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
260 frame's thread state.
261
Thomas Wouters6ed19652007-01-23 13:50:49 +0000262- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
263
Martin v. Löwis4885e7d2007-01-19 06:42:22 +0000264- Bug #1637022: Prefix AST symbols with _Py_.
265
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000266- Prevent seg fault on shutdown which could occur if an object
267 raised a warning.
268
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000269- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
270 to avoid relying on atexit.
271
Raymond Hettinger94547f72006-12-20 06:42:06 +0000272- Bug #1590891: random.randrange don't return correct value for big number
273
Georg Brandl283a1352006-11-19 08:48:30 +0000274- Patch #1586791: Better exception messages for some operations on strings,
275 tuples and lists.
276

282
Georg Brandlb9f4ad32006-10-29 18:31:42 +0000283- Bug #1576657: when setting a KeyError for a tuple key, make sure that
284 the tuple isn't used as the "exception arguments tuple".
285
Neal Norwitz21997af2006-10-28 21:19:07 +0000286- Bug #1565514, SystemError not raised on too many nested blocks.
287
Thomas Hellerdf08f0b2006-10-27 18:31:36 +0000288- Bug #1576174: WindowsError now displays the windows error code
289 again, no longer the posix error code.
290
Martin v. Löwisb5bc5372006-10-27 06:16:31 +0000291- Patch #1549049: Support long values in structmember, issue warnings

698 and TestSuite subclasses (not instances) are no longer accepted in

1018 time so that opening a database previously created with the DB_DUP or
1019 DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
1020 Specifically: dictionary assignment to a DB object will replace all
1021 values for a given key when the database allows duplicate values.
1022 DB users should use DB.put(k, v) when they want to store duplicates; not
1023 DB[k] = v.
1024

1348
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001349- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001350 compared equal or unequal to a string and a UnicodeDecodeError
1351 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001352
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001353 Instead, the equal (==) and unequal (!=) comparison operators will
1354 now issue a UnicodeWarning and interpret the two objects as
1355 unequal. The UnicodeWarning can be filtered as desired using
1356 the warning framework, e.g. silenced completely, turned into an
1357 exception, logged, etc.
1358
1359 Note that compare operators other than equal and unequal will still
1360 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001361
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001362- Fix segfault when doing string formatting on subclasses of long.
1363
1364- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1365 with new-style classes.
1366
1367- Fix bug related to __len__ functions returning negative values with
1368 classic classes.
1369
1370- Patch #1538606, Fix __index__() clipping. There were some problems
1371 discovered with the API and how integers that didn't fit into Py_ssize_t
1372 were handled. This patch attempts to provide enough alternatives
1373 to effectively use __index__.
1374
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001375- Bug #1536021: __hash__ may now return long int; the final hash
1376 value is obtained by invoking hash on the long int.
1377
Thomas Hellerab1049c2006-08-08 17:37:00 +00001378- Bug #1536786: buffer comparison could emit a RuntimeWarning.

1381 sys.stdin is closed.
1382
Thomas Heller74d36f02006-08-04 18:17:40 +00001383- On Windows, the PyErr_Warn function is now exported from
1384 the Python dll again.
1385
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001386- Bug #1191458: tracing over for loops now produces a line event
1387 on each iteration. Fixing this problem required changing the .pyc
1388 magic number. This means that .pyc files generated before 2.5c1
1389 will be regenerated.
1390
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001391- Bug #1333982: string/number constants were inappropriately stored
1392 in the byte code and co_consts even if they were not used, ie
1393 immediately popped off the stack.
1394
Georg Brandle9462c72006-08-04 18:03:37 +00001395- Fixed a reference-counting problem in property().

1400
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001401- Fix a bug in the ``compiler`` package that caused invalid code to be
1402 generated for generator expressions.
1403
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001404- The distutils version has been changed to 2.5.0. The change to
1405 keep it programmatically in sync with the Python version running
1406 the code (introduced in 2.5b3) has been reverted. It will continue
1407 to be maintained manually as static string literal.
1408
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001409- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001410 and this cannot be converted to the required C type, an exception is
1411 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001412 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001413
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001414- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001415 an exception.
1416
Tim Petersc10c9d02006-09-05 02:18:09 +00001417- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001418 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001419 workarounds for clocks with low resolution, to stop the code yielding
1420 duplicate UUIDs.
1421
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001422- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1423 before raising SystemExit, allowing IDLE to honor quit() and exit().
1424
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001425- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001430- logging's atexit hook now runs even if the rest of the module has
1431 already been cleaned up.
1432

1452
Thomas Heller86720042006-08-14 11:17:48 +00001453- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1454 uses the _as_parameter_ attribute when objects are passed to foreign
1455 function calls. The ctypes version number was changed to 1.0.1.
1456
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001457- Bug #1530559, struct.pack raises TypeError where it used to convert.

Fred Drake53912162006-07-29 13:22:49 +00001504What's New in Python 2.5 beta 3?
1505================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001506
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001507*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001508
1509Core and builtins
1510-----------------
1511
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001512- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001513 returned a long (see PEP 353).
1514
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001515- Bug #1515471: string.replace() accepts character buffers again.
1516
Neal Norwitz07aadb12006-07-30 06:55:48 +00001517- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1518 This provides the proper warning for struct.pack().
1519 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1520
Neal Norwitz0d62a062006-07-30 06:53:31 +00001521- Patch #1531113: Fix augmented assignment with yield expressions.
1522 Also fix a SystemError when trying to assign to yield expressions.
1523
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001524- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1525 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1526 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1527 excessive filesystem operations during imports.
1528
Tim Petersbc24eee2006-07-27 01:14:53 +00001529- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1530 operations on signed longs that are formally undefined by C.
1531 Unfortunately, at least one compiler now cares about that, so complicated
1532 the code to make that compiler happy again.
1533
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001534- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1535
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001536- Patch #1232023: Stop including current directory in search
1537 path on Windows.
1538
Neal Norwitze1fdb322006-07-21 05:32:28 +00001539- Fix some potential crashes found with failmalloc.
1540
Neal Norwitze7563102006-07-17 01:00:16 +00001541- Fix warnings reported by Klocwork's static analysis tool.
1542
Neal Norwitz84be93b2006-07-16 01:50:38 +00001543- Bug #1512814, Fix incorrect lineno's when code within a function
1544 had more than 255 blank lines.
1545
Georg Brandl9dceedb2006-07-12 15:31:17 +00001546- Patch #1521179: Python now accepts the standard options ``--help`` and
1547 ``--version`` as well as ``/?`` on Windows.
1548
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001549- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001550 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001551 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001552
Tim Peters112aad32006-07-19 00:03:19 +00001553- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001554 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001555 new ``sys._current_frames()`` returns a dictionary with one entry,
1556 mapping the faux "thread id" 0 to the current frame.
1557
Ronald Oussoren3075e162006-07-25 20:28:55 +00001558- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001559
Ronald Oussoren3075e162006-07-25 20:28:55 +00001560
Neal Norwitza1f10902006-07-12 07:28:29 +00001561Library
1562-------
1563
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001564- Correction of patch #1455898: In the mbcs decoder, set final=False
1565 for stream decoder, but final=True for the decode function.
1566
Georg Brandl07fec3a2006-08-01 18:49:24 +00001567- os.urandom no longer masks unrelated exceptions like SystemExit or
1568 KeyboardInterrupt.
1569
Tim Peters4643c2f2006-08-10 22:45:34 +00001570- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001571 shutil.copytree on Windows
1572
Georg Brandle34ac7c2006-07-30 11:07:23 +00001573- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1574 refers to file descriptors, not file objects.
1575
Tim Petersc10c9d02006-09-05 02:18:09 +00001576- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001577 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001578 #1513611, and probably others.
1579
Georg Brandledd9b0d2006-07-29 09:33:26 +00001580- Bug #1441397: The compiler module now recognizes module and function
1581 docstrings correctly as it did in Python 2.4.
1582
Tim Peters6f681472006-07-27 23:44:37 +00001583- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1584 lost that tests are sorted by name before being run. This rarely
1585 matters for well-written tests, but can create baffling symptoms if
1586 side effects from one test to the next affect outcomes. ``DocTestFinder``
1587 has been changed to sort the list of tests it returns.
1588
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001589- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001590 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001591
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001592- Bug #978833: Really close underlying socket in _socketobject.close.
1593
Georg Brandl8c036cc2006-08-20 13:15:39 +00001594- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1595 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001596
Georg Brandlcf0c1722006-07-26 07:23:32 +00001597- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1598 to recursive calls and call it with the failing package name.
1599
Martin v. Löwis0b483032006-07-25 09:53:12 +00001600- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1601
Georg Brandlc13c34c2006-07-24 14:09:56 +00001602- Patch #1515343: Fix printing of deprecated string exceptions with a
1603 value in the traceback module.
1604
Greg Ward48fae7a2006-07-23 16:05:51 +00001605- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1606
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001607- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1608
Brett Cannoncaebe222006-07-18 04:41:36 +00001609- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1610 argument tuple. For arguments where zero is illegal, the value is forced to
1611 the minimum value that is correct. This is to support an undocumented but
1612 common way people used to fill in inconsequential information in the time
1613 tuple pre-2.4.
1614
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001615- Patch #1220874: Update the binhex module for Mach-O.
1616
Barry Warsawb110bad2006-07-21 14:51:07 +00001617- The email package has improved RFC 2231 support, specifically for
1618 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1619 (name*0=<blah>) parameter continuations. This may change the types of
1620 values returned from email.message.Message.get_param() and friends.
1621 Specifically in some cases where non-encoded continuations were used,
1622 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1623 will just return the string (since non-encoded continuations don't have
1624 charset and language parts).
1625
1626 Also, whereas % values were decoded in all parameter continuations, they are
1627 now only decoded in encoded parameter parts.
1628
Ronald Oussoren3075e162006-07-25 20:28:55 +00001629- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1630
1631- Bug #1517996: IDLE now longer shows the default Tk menu when a
1632 path browser, class browser or debugger is the frontmost window on MacOS X
1633
Barry Warsaw00decd72006-07-27 23:43:15 +00001634- Patch #1520294: Support for getset and member descriptors in types.py,
1635 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1636 of an object against these built-in types and more importantly, for getting
1637 their docstrings printed in the interactive interpreter's help() function.

1641-----------------
1642
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001643- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1644 a socket operation on a socket with a timeout, the exception will be
1645 caught correctly. Previously, the exception was not caught.
1646
Thomas Heller1393d6a2006-07-28 21:43:20 +00001647- Patch #1529514: The _ctypes extension is now compiled on more
1648 openbsd target platforms.
1649
Tim Peters9cab5932006-07-28 00:30:00 +00001650- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1651 a memory leak, affecting pickles and deep copies.
1652
Tim Petersbc24eee2006-07-27 01:14:53 +00001653- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001654 Paul Eggert.
1655
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001656- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1657
Thomas Hellerce049a02006-07-14 17:51:14 +00001658- Patch #1521817: Index range checking on ctypes arrays containing
1659 exactly one element enabled again. This allows iterating over these
1660 arrays, without the need to check the array size before.
1661
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001662- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001663 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001664 /dev/null in certain cases; this is now fixed.
1665
Thomas Heller47d7a062006-07-12 08:43:47 +00001666- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1667 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001668
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001669- Because of a misspelled preprocessor symbol, ctypes was always
1670 compiled without thread support; this is now fixed.
1671
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001672- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1673 methods now allow their database parameter to be None as the
1674 sleepycat API allows.
1675
Matt Flemingec926502006-07-28 11:27:27 +00001676- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1677 bluetooth API compared with Linux and FreeBSD.
1678
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001679Tests
1680-----
1681
1682- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1683 how long the test file should take to play. Now accepts taking 2.93 secs
1684 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1685
Georg Brandl4793aa32006-07-28 18:31:39 +00001686- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1687 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1688 run via ``regrtest.py``. Now they do.

1698- PythonLauncher now works correctly when the path to the script contains
1699 characters that are treated specially by the shell (such as quotes).
1700
1701- Bug #1527397: PythonLauncher now launches scripts with the working directory
1702 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001703 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001704 expect.

1729 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001730
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001731- Bug #1519018: 'as' is now validated properly in import statements.
1732
Neal Norwitz28746ab2006-07-09 22:14:42 +00001733- On 64 bit systems, int literals that use less than 64 bits are
1734 now ints rather than longs.
1735
Neal Norwitzed657552006-07-10 00:04:44 +00001736- Bug #1512814, Fix incorrect lineno's when code at module scope
1737 started after line 256.
1738
Tim Peters32a83612006-07-10 21:08:24 +00001739- New function ``sys._current_frames()`` returns a dict mapping thread
1740 id to topmost thread stack frame. This is for expert use, and is
1741 especially useful for debugging application deadlocks. The functionality
1742 was previously available in Fazal Majid's ``threadframe`` extension
1743 module, but it wasn't possible to do this in a wholly threadsafe way from
1744 an extension.

1761
Thomas Woutersadd19112006-07-05 11:03:49 +00001762- string.Template() now correctly handles tuple-values. Previously,
1763 multi-value tuples would raise an exception and single-value tuples would
1764 be treated as the value they contain, instead.
1765
Martin v. Löwisede77f52006-07-03 13:01:35 +00001766- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

Brett Cannon53ab5b72006-06-22 16:49:14 +00001792- Bug #1510580: The 'warnings' module improperly required that a Warning
1793 category be either a types.ClassType and a subclass of Warning. The proper
1794 check is just that it is a subclass with Warning as the documentation states.
1795
Georg Brandlad29e632006-06-21 17:45:17 +00001796- The compiler module now correctly compiles the new try-except-finally

Tim Peters112aad32006-07-19 00:03:19 +00001811- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1812 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1813 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001814
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001815- Assigning None to pointer type fields in ctypes structures possible
1816 overwrote the wrong fields, this is fixed now.
1817
1818- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1819 on non-Windows platforms.
1820
1821- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1822 integer or long, without range checking.
1823
1824- Patch #1517790: It is now possible to use custom objects in the ctypes
1825 foreign function argtypes sequence as long as they provide a from_param
1826 method, no longer is it required that the object is a ctypes type.
1827
1828- The '_ctypes' extension module now works when Python is configured
1829 with the --without-threads option.

1846
Tim Peters32a83612006-07-10 21:08:24 +00001847- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001848 Previously, the slight difference could cause compilation errors of the
1849 'zlib' module on systems with more than one version of zlib.
1850
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001851- The MSI compileall step was fixed to also support a TARGETDIR

1882Core and builtins
1883-----------------
1884
Georg Brandla56b9152006-06-19 06:35:54 +00001885- Patch #1507676: Error messages returned by invalid abstract object operations
1886 (such as iterating over an integer) have been improved and now include the
1887 type of the offending object to help with debugging.
1888
Brett Cannonea3912b2006-06-13 21:46:41 +00001889- Bug #992017: A classic class that defined a __coerce__() method that returned
1890 its arguments swapped would infinitely recurse and segfault the interpreter.
1891
Neal Norwitz909eb122006-06-12 02:13:21 +00001892- Fix the socket tests so they can be run concurrently.
1893
Neal Norwitzb9845e72006-06-12 02:11:18 +00001894- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001895 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001896
Brett Cannon22565aa2006-06-09 22:31:23 +00001897- Bug #532646: object.__call__() will continue looking for the __call__
1898 attribute on objects until one without one is found. This leads to recursion
1899 when you take a class and set its __call__ attribute to an instance of the
1900 class. Originally fixed for classic classes, but this fix is for new-style.
1901 Removes the infinite_rec_3 crasher.
1902
Georg Brandl24250812006-06-09 18:45:48 +00001903- The string and unicode methods startswith() and endswith() now accept
1904 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1905
Brett Cannonde3b0522006-06-08 17:00:45 +00001906- Buffer objects, at the C level, never used the char buffer
1907 implementation even when the char buffer for the wrapped object was
1908 explicitly requested (originally returned the read or write buffer).
1909 Now a TypeError is raised if the char buffer is not present but is
1910 requested.
1911
Georg Brandlddbaa662006-06-04 21:56:52 +00001912- Patch #1346214: Statements like "if 0: suite" are now again optimized
1913 away like they were in Python 2.4.
1914
Georg Brandlb7c8f542006-05-27 12:30:25 +00001915- Builtin exceptions are now full-blown new-style classes instead of
1916 instances pretending to be classes, which speeds up exception handling
1917 by about 80% in comparison to 2.5a2.
1918
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001919- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1920 Unicode 4.1.
1921
Georg Brandlf4ef1162006-05-26 18:03:31 +00001922- Patch #921466: sys.path_importer_cache is now used to cache valid and
1923 invalid file paths for the built-in import machinery which leads to
1924 fewer open calls on startup.
1925
Tim Peters696cf432006-05-24 21:10:40 +00001926- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1927 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1928 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1929 the number of input digits (it was and remains linear-time for bases
1930 2, 4, 8, 16 and 32).
1931
Tim Petersb713ec22006-05-23 18:45:30 +00001932- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1933 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1934 an integer close to ``sys.maxint``. This was repaired by patch
1935 #1335972, which also gives a nice speedup.
1936
Richard Jonescebbefc2006-05-23 18:28:17 +00001937- Patch #1337051: reduced size of frame objects.
1938
1939- PyErr_NewException now accepts a tuple of base classes as its
1940 "base" parameter.
1941
Richard Jones7c88dcc2006-05-23 10:37:38 +00001942- Patch #876206: function call speedup by retaining allocated frame
1943 objects.
1944
Georg Brandl7b90e162006-05-18 07:01:27 +00001945- Bug #1462152: file() now checks more thoroughly for invalid mode
1946 strings and removes a possible "U" before passing the mode to the
1947 C library function.
1948
Neal Norwitz1004a532006-05-15 07:17:23 +00001949- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1950
Neal Norwitz373f0a72006-05-15 07:04:36 +00001951- Bug #1487966: Fix SystemError with conditional expression in assignment
1952
Martin v. Löwis879768d2006-05-11 13:28:43 +00001953- WindowsError now has two error code attributes: errno, which carries
1954 the error values from errno.h, and winerror, which carries the error
1955 values from winerror.h. Previous versions put the winerror.h values
1956 (from GetLastError()) into the errno attribute.
1957
Martin v. Löwis77736712006-05-04 05:51:03 +00001958- Patch #1475845: Raise IndentationError for unexpected indent.
1959
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001960- Patch #1479181: split open() and file() from being aliases for each other.
1961
Tim Peters44bd9862006-06-01 13:49:23 +00001962- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1963 methods were always silently ignored by dictionaries when comparing keys.
1964 They are now passed through (except when using the C API function
1965 ``PyDict_GetItem()``, whose semantics did not change).
1966
1967- Bug #1456209: In some obscure cases it was possible for a class with a
1968 custom ``__eq__()`` method to confuse dict internals when class instances
1969 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1970 No, you don't have any code that did this ;-)

Brett Cannon6ee7d012006-06-08 16:23:04 +00001979- Change binascii.hexlify to accept a read-only buffer instead of only a char
1980 buffer and actually follow its documentation.
1981
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001982- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1983
Nick Coghlanc649ec52006-05-29 12:43:05 +00001984- Patch #1478788 (modified version): The functional extension module has
1985 been renamed to _functools and a functools Python wrapper module added.
1986 This provides a home for additional function related utilities that are
1987 not specifically about functional programming. See PEP 309.
1988
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001989- Patch #1493701: performance enhancements for struct module.

1995
Andrew MacIntyre92913322006-06-13 15:04:24 +00001996- Patch #1454481: thread stack size is now tunable at runtime for thread
1997 enabled builds on Windows and systems with Posix threads support.
1998
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001999- On Win32, os.listdir now supports arbitrarily-long Unicode path names
2000 (up to the system limit of 32K characters).
2001
2002- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
2003 As a result, these functions now raise WindowsError instead of OSError.
2004
Tim Peters7a822da2006-05-25 21:50:17 +00002005- ``time.clock()`` on Win64 should use the high-performance Windows
2006 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
2007 Windows platforms).
2008
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002009- Calling Tk_Init twice is refused if the first call failed as that
2010 may deadlock.
2011
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00002012- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
2013 accept it without potentially using an uninitialized pointer.
2014
2015- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
2016 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smith372b5832006-06-05 18:48:21 +00002022- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
2023 parameter is supplied. [SF pybsddb bug #1477863]
2024
Gregory P. Smith3c228b12006-06-05 23:59:37 +00002025- bsddb: the __len__ method of a DB object has been fixed to return correct
2026 results. It could previously incorrectly return 0 in some cases.
2027 Fixes SF bug 1493322 (pybsddb bug 1184012).
2028
Gregory P. Smithff7d9912006-06-08 05:17:08 +00002029- bsddb: the bsddb.dbtables Modify method now raises the proper error and
2030 aborts the db transaction safely when a modifier callback fails.
2031 Fixes SF python patch/bug #1408584.
2032
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002033- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00002034 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002035 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
2036 database calls that would previously deadlock. [SF python bug #775414]
2037
Vinay Sajip28e57612006-07-01 10:45:20 +00002038- Patch #1446489: add support for the ZIP64 extensions to zipfile.

2060 mime.types file for determining MIME types.
2061
Georg Brandl2605ca82006-06-14 06:08:31 +00002062- Bug #1339007: Shelf objects now don't raise an exception in their
2063 __del__ method when initialization failed.
2064
Martin v. Löwisd8251432006-06-14 05:21:04 +00002065- Patch #1455898: The MBCS codec now supports the incremental mode for
2066 double-byte encodings.
2067
Tim Peters43898b42006-06-14 04:09:25 +00002068- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2069 guarantee that adjacent triples in the return list always describe
2070 non-adjacent blocks. Previously, a pair of matching blocks could end
2071 up being described by multiple adjacent triples that formed a partition
2072 of the matching pair.
2073
Greg Ward0e0c9f42006-06-11 16:24:11 +00002074- Bug #1498146: fix optparse to handle Unicode strings in option help,
2075 description, and epilog.
2076
Greg Wardd1c797e2006-06-11 14:42:41 +00002077- Bug #1366250: minor optparse documentation error.
2078
Greg Ward7f547402006-06-11 00:40:49 +00002079- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
2080 clarify docs.
2081
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002082- The wsgiref package has been added to the standard library.
2083
Nick Coghlan676725d2006-06-08 13:54:49 +00002084- The functions update_wrapper() and wraps() have been added to the functools
2085 module. These make it easier to copy relevant metadata from the original
2086 function when writing wrapper functions.
2087
Tim Petersd6a9eef2006-06-05 01:48:21 +00002088- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2089 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002090
Martin v. Löwis3f767792006-06-04 19:36:28 +00002091- Patch #1359618: Speed up charmap encoder by using a trie structure
2092 for lookup.
2093
Tim Petersd609b1a2006-06-02 23:22:51 +00002094- The functions in the ``pprint`` module now sort dictionaries by key
2095 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2096 if and only if its display required more than one line, although that
2097 wasn't documented. The new behavior increases predictability; e.g.,
2098 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2099
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002100- Patch #1497027: try HTTP digest auth before basic auth in urllib2
2101 (thanks for J. J. Lee).
2102
Georg Brandl2b330372006-05-28 20:23:12 +00002103- Patch #1496206: improve urllib2 handling of passwords with respect to
2104 default HTTP and HTTPS ports.
2105
George Yoshidaf3c65de2006-05-28 16:39:09 +00002106- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
2107
Bob Ippolito7298f272006-05-23 18:43:47 +00002108- Patch #1281707: speed up gzip.readline.
2109
Georg Brandlb89316f2006-05-17 15:51:16 +00002110- Patch #1180296: Two new functions were added to the locale module:
2111 format_string() to get the effect of "format % items" but locale-aware,
2112 and currency() to format a monetary number with currency sign.
2113
Georg Brandle3a25832006-05-17 14:56:04 +00002114- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2115 and several features added, such as speed and geometry control.
2116
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002117- Patch #1488881: add support for external file objects in bz2 compressed
2118 tarfiles.
2119
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002120- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2121 stdout arguments, making it possible to redirect input and output
2122 for remote debugging.
2123
2124- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2125 a couple of issues, notably handling of long file names using the
2126 GNU LONGNAME extension.
2127
2128- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2129 new flag when ``name`` is already the name of an option flag.
2130
2131- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2132 package.
2133
2134- Patch #1472854: make the rlcompleter.Completer class usable on non-
2135 UNIX platforms.
2136
2137- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
2138
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00002139- Bug #1472827: correctly escape newlines and tabs in attribute values in
2140 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002170What's New in Python 2.5 alpha 2?
2171=================================
2172
2173*Release date: 27-APR-2006*
2174
2175Core and builtins
2176-----------------
2177
Thomas Heller1b046642006-04-18 18:51:06 +00002178- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2179 by converting these apis from macros into exported functions again:
2180
2181 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2182 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2183 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2184 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2185 PyRun_String Py_CompileString
2186
Martin v. Löwis45294a92006-04-18 06:24:08 +00002187- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2188
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002189- All uses of PyStructSequence_InitType have been changed to initialize
2190 the type objects only once, even if the interpreter is initialized
2191 multiple times.
2192
Neal Norwitz61546162006-04-14 05:20:28 +00002193- Bug #1454485, array.array('u') could crash the interpreter. This was
2194 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2195 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2196
2197- Py_UNICODE is unsigned. It was always documented as unsigned, but
2198 due to a bug had a signed value in previous versions.
2199
Tim Peters3a5e8b12006-04-11 01:44:07 +00002200- Patch #837242: ``id()`` of any Python object always gives a positive
2201 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2202 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002203 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002204 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002205
Tim Peters3a5e8b12006-04-11 01:44:07 +00002206 def __hash__(self):
2207 return id(self) # WRONG
2208
2209 because a hash result must be a (short) Python int but it was always
2210 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002211 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002212 was always usable as a hash value before this patch. That's no longer
2213 necessarily so.
2214
2215- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002216 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002217 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002218 #1454844)
2219
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002220- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2221 involving generators that have paused outside of any ``try`` or ``with``
2222 blocks. (In 2.5a1, a paused generator that was part of a reference
2223 cycle could not be garbage collected, regardless of whether it was
2224 paused in a ``try`` or ``with`` block.)

2243- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2244 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002245
Armin Rigoa9017c32006-04-19 11:50:27 +00002246- Patch #1062014: AF_UNIX sockets under Linux have a special

2255
Tim Peters711bf302006-04-25 03:31:36 +00002256- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2257 a doctest to be skipped (the code is not run, and the expected output
2258 or exception is ignored).
2259
Nick Coghlanda2268f2006-04-24 04:37:15 +00002260- Fixed contextlib.nested to cope with exceptions being raised and
2261 caught inside exit handlers.
2262
Greg Wardab05edc2006-04-23 03:47:58 +00002263- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2264 hex, octal, or binary; add ``append_const`` action; keep going if
2265 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2266 added ``epilog`` for better help generation).
2267
Tim Peters21fbd572006-04-21 21:18:10 +00002268- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2269 called from a thread spawned as a side effect of importing a module.
2270
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002271- The pydoc module now supports documenting packages contained in
2272 .zip or .egg files.
2273
2274- The pkgutil module now has several new utility functions, such
2275 as ``walk_packages()`` to support working with packages that are either
2276 in the filesystem or zip files.
2277
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002278- The mailbox module can now modify and delete messages from
2279 mailboxes, in addition to simply reading them. Thanks to Gregory
2280 K. Johnson for writing the code, and to the 2005 Google Summer of
2281 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002282
Tim Petersc7605f22006-04-17 21:12:33 +00002283- The ``__del__`` method of class ``local`` in module ``_threading_local``
2284 returned before accomplishing any of its intended cleanup.
2285
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002286- Patch #790710: Add breakpoint command lists in pdb.

Martin v. Löwis10acfd02006-04-10 12:39:36 +00002324- Patch #1429775: Link extension modules with the shared libpython.
2325
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002326- Fixed a libffi build problem on MIPS systems.
2327
Tim Peters8931ff12006-05-13 23:28:20 +00002328- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2329 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2330 and "%zu" for unsigned integers of type ``size_t``.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002332Tests
2333-----
2334
Nick Coghlanda2268f2006-04-24 04:37:15 +00002335- test_contextlib now checks contextlib.nested can cope with exceptions
2336 being raised and caught inside exit handlers.
2337
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002338- test_cmd_line now checks operation of the -m and -c command switches
2339
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002340- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2341 it separately and by hand. It also wasn't cleaning up its changes to
2342 the current Decimal context.
2343
Thomas Woutersabd08882006-04-26 15:53:30 +00002344- regrtest.py now has a -M option to run tests that test the new limits of
2345 containers, on 64-bit architectures. Running these tests is only sensible
2346 on 64-bit machines with more than two gigabytes of memory. The argument
2347 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002355Documentation
2356-------------
2357
Tim Petersb06d28c2006-05-12 01:57:59 +00002358- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2359
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002360- PEP 343: Added Context Types section to the library reference
2361 and attempted to bring other PEP 343 related documentation into
2362 line with the implementation and/or python-dev discussions.
2363
Tim Peters8dc73d22006-04-24 02:03:16 +00002364- Bug #1337990: clarified that ``doctest`` does not support examples
2365 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002368What's New in Python 2.5 alpha 1?
2369=================================
2370
Anthony Baxterebed3f62006-04-03 15:03:44 +00002371*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002372
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002373Core and builtins
2374-----------------
2375
Nick Coghlan43832302006-04-23 17:04:07 +00002376- PEP 338: -m command line switch now delegates to runpy.run_module
2377 allowing it to support modules in packages and zipfiles
2378
Martin v. Löwisc661b882006-04-20 04:54:23 +00002379- On Windows, .DLL is not an accepted file name extension for
2380 extension modules anymore; extensions are only found if they
2381 end in .PYD.
2382
Martin v. Löwisea62d252006-04-03 10:56:49 +00002383- Bug #1421664: sys.stderr.encoding is now set to the same value as
2384 sys.stdout.encoding.
2385
Neal Norwitz92e212f2006-04-03 04:48:37 +00002386- __import__ accepts keyword arguments.
2387
Georg Brandlccadf842006-03-31 18:54:53 +00002388- Patch #1460496: round() now accepts keyword arguments.
2389
Anthony Baxter262c00a2006-03-30 10:53:17 +00002390- Fixed bug #1459029 - unicode reprs were double-escaped.
2391
Hye-Shik Changd478f342006-03-23 12:32:36 +00002392- Patch #1396919: The system scope threads are reenabled on FreeBSD
2393 5.4 and later versions.
2394
Neal Norwitze98ccf62006-03-23 05:39:47 +00002395- Bug #1115379: Compiling a Unicode string with an encoding declaration
2396 now gives a SyntaxError.
2397
Georg Brandlabd1ff82006-03-18 07:59:59 +00002398- Previously, Python code had no easy way to access the contents of a
2399 cell object. Now, a ``cell_contents`` attribute has been added
2400 (closes patch #1170323).
2401
Tim Peterscf79aac2006-03-16 01:14:46 +00002402- Patch #1123430: Python's small-object allocator now returns an arena to
2403 the system ``free()`` when all memory within an arena becomes unused
2404 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2405 freed. Some applications will see a drop in virtual memory size now,
2406 especially long-running applications that, from time to time, temporarily
2407 use a large number of small objects. Note that when Python returns an
2408 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002409 platform C library will in turn return that memory to the operating system.
2410 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002411 appears to be effective at least on Microsoft C and gcc-based systems.
2412 Thanks to Evan Jones for hard work and patience.
2413
Georg Brandl533ff6f2006-03-08 18:09:27 +00002414- Patch #1434038: property() now uses the getter's docstring if there is
2415 no "doc" argument given. This makes it possible to legitimately use
2416 property() as a decorator to produce a read-only property.
2417
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002418- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2419 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2420 of requiring an int or long in slicing and a few other contexts, enabling
2421 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2422
Neal Norwitz995acdf2006-03-07 05:01:00 +00002423- Fixed various bugs reported by Coverity's Prevent tool.
2424
Brett Cannonbf364092006-03-01 04:25:17 +00002425- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2426 new exception base class, BaseException, which has a new message attribute.
2427 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2428 Raising a string exception now raises a DeprecationWarning.
2429
Thomas Woutersfb609f42006-02-28 16:37:25 +00002430- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2431 explicitly relative, using 'from .module import name' to mean 'from the same
2432 package as this module is in. Imports without dots still default to the
2433 old relative-then-absolute, unless 'from __future__ import
2434 absolute_import' is used.
2435
Brett Cannona7446e32006-02-27 23:39:10 +00002436- Properly check if 'warnings' raises an exception (usually when a filter set
2437 to "error" is triggered) when raising a warning for raising string
2438 exceptions.
2439
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002440- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002441 The name was removed from Include/code.h.
2442
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002443- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002444
Guido van Rossum1968ad32006-02-25 22:38:04 +00002445- Patch 1433928:
2446 - The copy module now "copies" function objects (as atomic objects).
2447 - dict.__getitem__ now looks for a __missing__ hook before raising
2448 KeyError.
2449
Tim Peters84ef21c2006-02-28 20:39:06 +00002450- PEP 343: with statement implemented. Needs ``from __future__ import
2451 with_statement``. Use of 'with' as a variable will generate a warning.
2452 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002453 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002454 The following objects have __context__ methods:
2455 - The built-in file type.
2456 - The thread.LockType type.
2457 - The following types defined by the threading module:
2458 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2459 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002460
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002461- Fix the encodings package codec search function to only search
2462 inside its own package. Fixes problem reported in patch #1433198.
2463
2464 Note: Codec packages should implement and register their own
2465 codec search function. PEP 100 has the details.
2466
Tim Peters9ea89d22006-06-04 03:26:02 +00002467- PEP 353: Using ``Py_ssize_t`` as the index type.
2468
2469- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2470 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2471 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2472 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2473 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002474
Neal Norwitzfc76d632006-01-10 06:03:13 +00002475- Patch #1400181, fix unicode string formatting to not use the locale.
2476 This is how string objects work. u'%f' could use , instead of .
2477 for the decimal point. Now both strings and unicode always use periods.
2478
Neal Norwitz671b9e32006-01-09 07:07:12 +00002479- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2480 configure would break checking curses.h.
2481
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002482- Bug #959576: The pwd module is now builtin. This allows Python to be
2483 built on UNIX platforms without $HOME set.
2484
Neal Norwitzc10978f2005-12-19 06:07:16 +00002485- Bug #1072182, fix some potential problems if characters are signed.
2486
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002487- Bug #889500, fix line number on SyntaxWarning for global declarations.
2488
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002489- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2490
Neal Norwitze7214a12005-12-18 05:03:17 +00002491- Support for converting hex strings to floats no longer works.
2492 This was not portable. float('0x3') now raises a ValueError.
2493
Barry Warsaw2a38a862005-12-18 01:27:35 +00002494- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002495 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002496 is now displayed in interactive prompt banner.
2497
Georg Brandlfa166682005-12-17 21:45:17 +00002498- Implementation of PEP 341 - Unification of try/except and try/finally.
2499 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002500 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002501
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002502- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2503 now encodes backslash correctly.
2504
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002505- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2506
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002507- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002508 and long longs.
2509
Neal Norwitz67715f02005-11-09 06:59:35 +00002510- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002511 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002512 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002513
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002514- Replaced most Unicode charmap codecs with new ones using the
2515 new Unicode translate string feature in the builtin charmap
2516 codec; the codecs were created from the mapping tables available
2517 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2518 encodings now include a mapping for the Apple logo)
2519
Tim Peterse3547fd2005-12-16 23:13:57 +00002520- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002521
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002522- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002523
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002524- A new AST parser implementation was completed. The abstract
2525 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002526 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002527
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002528- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002529 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2530
Neal Norwitz708e51a2005-10-03 04:48:15 +00002531- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2532
Neal Norwitz11bd1192005-10-03 00:54:56 +00002533- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2534 Provide a warning when a directory is passed on the command line.
2535
Neal Norwitz40d37812005-10-02 01:48:49 +00002536- Fix segfault with invalid coding.
2537
2538- SF bug #772896: unknown encoding results in MemoryError.
2539
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002540- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002541 supported a __len__() method which evaluated to False when the iterator
2542 was empty.
2543
Guido van Rossum630db602005-09-20 18:49:54 +00002544- On 64-bit platforms, when __len__() returns a value that cannot be
2545 represented as a C int, raise OverflowError.
2546
Skip Montanarof8948ca2005-09-19 03:54:46 +00002547- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002548 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002549
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002550- SF bug #893549: parsing keyword arguments was broken with a few format
2551 codes.
2552
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002553- Changes donated by Elemental Security to make it work on AIX 5.3
2554 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2555 bug #105470: test_pwd fails on 64bit system (Opteron).
2556
Guido van Rossum539c6622005-09-14 17:49:54 +00002557- Changes donated by Elemental Security to make it work on HP-UX 11 on
2558 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2559
Georg Brandl4550b8d2005-08-26 06:43:52 +00002560- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002561 (fixes bug #1119418).
2562
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002563- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2564
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002565- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2566 exceptions that cause a function to exit.
2567
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002568- The implementation of set() and frozenset() was revised to use its
2569 own internal data structure. Memory consumption is reduced by 1/3
2570 and there are modest speed-ups as well. The API is unchanged.
2571
Tim Petersde7990b2005-07-17 23:45:23 +00002572- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2573
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002574- SF bug #1229429: PyObject_CallMethod failed to decrement some
2575 reference counts in some error exit cases.
2576
Tim Petersecc6e6a2005-07-10 22:30:55 +00002577- SF bug #1185883: Python's small-object memory allocator took over
2578 a block managed by the platform C library whenever a realloc specified
2579 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002580 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002581 portable way to copy data from the C-managed block into Python's
2582 small-object space without risking a memory fault. Python's small-object
2583 realloc now leaves such blocks under the control of the platform C
2584 realloc.
2585
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002586- SF bug #1232517: An overflow error was not detected properly when
2587 attempting to convert a large float to an int in os.utime().
2588
Raymond Hettinger3296e692005-06-29 23:29:56 +00002589- SF bug #1224347: hex longs now print with lowercase letters just
2590 like their int counterparts.
2591
Michael W. Hudson188d4362005-06-20 16:52:57 +00002592- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2593 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2594 interpreter states; back out that fix and do a better job (see
2595 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2596 for a longer write-up of the problem).
2597
Michael W. Hudsondf888462005-06-03 14:41:55 +00002598- SF patch #1180995: marshal now uses a binary format by default when
2599 serializing floats.
2600
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002601- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2602 the routines that promise to produce IEEE 754 binary representations
2603 of floats now simply copy bytes around.
2604
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002605- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2606 278.
2607
Brett Cannonc3647ac2005-04-26 03:45:26 +00002608- patch #1109424: int, long, float, complex, and unicode now check for the
2609 proper magic slot for type conversions when subclassed. Previously the
2610 magic slot was ignored during conversion. Semantics now match the way
2611 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002612 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002613 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002614 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002615
Barry Warsawc8d907c2005-04-19 23:43:40 +00002616- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2617 NULL, now raise an AttributeError when attempting to set or delete the
2618 attribute. Previously a TypeError was raised, but this was inconsistent
2619 with the equivalent pure-Python implementation.
2620
Michael W. Hudson774479c2005-04-18 08:46:17 +00002621- It is now safe to call PyGILState_Release() before
2622 PyEval_InitThreads() (note that if there is reason to believe there
2623 are multiple threads around you still must call PyEval_InitThreads()
2624 before using the Python API; this fix is for extension modules that
2625 have no way of knowing if Python is multi-threaded yet).
2626
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002627- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2628 disabled caused a crash.
2629
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002630- Bug #1165306: instancemethod_new allowed the creation of a method
2631 with im_class == im_self == NULL, which caused a crash when called.
2632
Tim Petersecc6e6a2005-07-10 22:30:55 +00002633- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002634 fixes the crash seen in bug #1165761
2635
Raymond Hettinger96229b12005-03-11 06:49:40 +00002636- Added two new builtins, any() and all().
2637
Brett Cannon409d8f22005-03-05 06:47:57 +00002638- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002639 (e.g., ``class C(): pass`` is no longer a syntax error).
2640 Patch #1176012 added support to the 'parser' module and 'compiler' package
2641 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002642
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002643- Patch #1115086: Support PY_LONGLONG in structmember.
2644
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002645- Bug #1155938: new style classes did not check that __init__() was
2646 returning None.
2647
Tim Petersecc6e6a2005-07-10 22:30:55 +00002648- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002649 ('\') with a specific error message.
2650
Martin v. Löwisff232d72005-03-03 09:24:38 +00002651- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2652
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002653- Bug #1124295: the __name__ attribute of file objects was
2654 inadvertently made inaccessible in restricted mode.
2655
Tim Petersecc6e6a2005-07-10 22:30:55 +00002656- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002657 an ferror() call.
2658
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002659- min() and max() now support key= arguments with the same meaning as in
2660 list.sort().
2661
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002662- The peephole optimizer now performs simple constant folding in expressions:
2663 (2+3) --> (5).
2664
Raymond Hettingera422c342005-01-11 03:03:27 +00002665- set and frozenset objects can now be marshalled. SF #1098985.
2666
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002667- Bug #1077106: Poor argument checking could cause memory corruption
2668 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002669
Jeremy Hyltonab630502005-02-04 18:44:06 +00002670- The parser did not complain about future statements in illegal
2671 positions. It once again reports a syntax error if a future
2672 statement occurs after anything other than a doc string.
2673
Neil Schemenauercf52c072005-08-12 17:34:58 +00002674- Change the %s format specifier for str objects so that it returns a
2675 unicode instance if the argument is not an instance of basestring and
2676 calling __str__ on the argument returns a unicode instance.
2677
Tim Petersf4e69282006-02-27 17:15:31 +00002678- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2679 current thread state when the auto-GIL-state machinery knows about
2680 it (since the thread state is being deleted, continuing to remember it
2681 can't help, but can hurt if another thread happens to get created with
2682 the same thread id).
2683

2712 for applications that require this specific version (such as IDNA).
2713
Neal Norwitzb62c4332006-03-04 18:35:47 +00002714- The timing module is no longer built by default. It was deprecated

Raymond Hettingerb2594052004-12-05 09:25:51 +00002861- itertools.islice() now accepts None for the start and step arguments.
2862 This allows islice() to work more readily with slices:
2863 islice(s.start, s.stop, s.step)

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002874- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2875 been renamed to have only a single underscore prefix. This was done to
2876 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002877
Nick Coghlan43832302006-04-23 17:04:07 +00002878- PEP 338: new module runpy defines a run_module function to support
2879 executing modules which provide access to source code or a code object
2880 via the PEP 302 import mechanisms.
2881
Anthony Baxter93f5b932006-04-03 08:05:07 +00002882- The email module's parsedate_tz function now sets the daylight savings

2890 in attribute values.
2891
Anthony Baxterc51ee692006-04-01 00:57:31 +00002892- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002893 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002894 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002895 module will not be built.
2896
Tim Petersc17976e2006-04-01 00:26:53 +00002897- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2898 aren't officially supported here, and trying to use them will probably
2899 raise an exception some day. But dicts have been allowed, and "mostly
2900 worked", so support for them won't go away without warning.
2901
Georg Brandl338ef7d2006-03-31 18:42:16 +00002902- Bug #1445068: getpass.getpass() can now be given an explicit stream

2920
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002921- email 4.0 package now integrated. This is largely the same as the email 3.0
2922 package that was included in Python 2.3, except that PEP 8 module names are
2923 now used (e.g. mail.message instead of email.Message). The MIME classes
2924 have been moved to a subpackage (e.g. email.mime.text instead of
2925 email.MIMEText). The old names are still supported for now. Several
2926 deprecated Message methods have been removed and lots of bugs have been
2927 fixed. More details can be found in the email package documentation.
2928
Walter Dörwald40108c92006-03-27 08:15:44 +00002929- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2930 (a subclass of tuple) that provides incremental decoders and encoders
2931 (a way to use stateful codecs without the stream API). Python functions
2932 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2933 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2934 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002935
Walter Dörwald067db482006-03-15 22:17:27 +00002936- Patch #1359365: Calling next() on a closed StringIO.String object raises
2937 a ValueError instead of a StopIteration now (like file and cString.String do).
2938 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2939 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00003013 SHA1, 224, 256, 384, and 512. Note that recent developments make the
3014 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
3015 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
3016 Ronald L. Rivest offered this advice for Python:
3017
3018 "The consensus of researchers in this area (at least as
3019 expressed at the NIST Hash Function Workshop 10/31/05),
3020 is that SHA-256 is a good choice for the time being, but
3021 that research should continue, and other alternatives may
3022 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00003023
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00003024- Added a subset of Fredrik Lundh's ElementTree package. Available

Raymond Hettinger68c04532005-06-10 11:05:19 +00003121 the generate_tokens() function now accepts a callable argument that
3122 terminates by raising StopIteration.
3123
Georg Brandl9166e1a2005-06-04 09:20:03 +00003124- Bug #1196315: fix weakref.WeakValueDictionary constructor.
3125
Georg Brandl268e61c2005-06-03 14:28:50 +00003126- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
3127 component of the path.
3128
Skip Montanaro174dd222005-05-14 20:54:16 +00003129- Patch #1120353: The xmlrpclib module provides better, more transparent,
3130 support for datetime.{datetime,date,time} objects. With use_datetime set
3131 to True, applications shouldn't have to fiddle with the DateTime wrapper
3132 class at all.
3133
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00003134- distutils.commands.upload was added to support uploading distribution
3135 files to PyPI.
3136
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00003137- distutils.commands.register now encodes the data as UTF-8 before posting
3138 them to PyPI.
3139
Raymond Hettinger267b8682005-03-27 10:47:39 +00003140- decimal operator and comparison methods now return NotImplemented
3141 instead of raising a TypeError when interacting with other types. This
3142 allows other classes to implement __radd__ style methods and have them
3143 work as expected.
3144
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003145- Bug #1163325: Decimal infinities failed to hash. Attempting to
3146 hash a NaN raised an InvalidOperation instead of a TypeError.
3147
Tim Petersecc6e6a2005-07-10 22:30:55 +00003148- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00003149 stream compression; add, for symmetry reasons, r:* as a synonym of r.
3150
Martin v. Löwis00a73e72005-03-04 19:40:34 +00003151- Patch #1043890: Add extractall method to tarfile.
3152
Martin v. Löwisc72dd382005-03-04 13:50:17 +00003153- Patch #1075887: Don't require MSVC in distutils if there is nothing
3154 to build.
3155
Martin v. Löwis637431b2005-03-03 23:12:42 +00003156- Patch #1103407: Properly deal with tarfile iterators when untarring
3157 symbolic links on Windows.
3158
Tim Petersecc6e6a2005-07-10 22:30:55 +00003159- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00003160 profile.py if available.
3161
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00003162- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
3163
Martin v. Löwisc5574e82005-03-03 10:57:37 +00003164- Patch #1117454: Remove code to special-case cookies without values
3165 in LWPCookieJar.
3166
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00003167- Patch #1117339: Add cookielib special name tests.
3168
Martin v. Löwise869eb12005-03-03 09:46:07 +00003169- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
3170
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00003171- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
3172
Martin v. Löwisdf241532005-03-03 08:17:42 +00003173- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
3174
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00003175- Patch #1104111: Alter setup.py --help and --help-commands.
3176
Martin v. Löwis4afe1542005-03-01 08:09:28 +00003177- Patch #1121234: Properly cleanup _exit and tkerror commands.
3178
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00003179- Patch #1049151: xdrlib now unpacks booleans as True or False.
3180
Raymond Hettingerbab41432005-02-05 01:31:19 +00003181- Fixed bug in a NameError bug in cookielib. Patch #1116583.
3182
Guido van Rossumd0641422005-02-03 15:01:24 +00003183- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3184 disables recursive traversal through instance attributes, which can
3185 be exploited in various ways.
3186
Tim Peterse3547fd2005-12-16 23:13:57 +00003187- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003188 flags on the HTTP listening socket.
3189
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003190- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3191 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3192
Fred Drakefbdeaad2006-07-29 16:56:15 +00003193- Patches #893642, #1039083: add allow_none, encoding arguments to
3194 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003195
Martin v. Löwis1d11de62005-01-29 13:29:23 +00003196- Bug #1110478: Revert os.environ.update to do putenv again.
3197
Thomas Hellerd6c6e222005-01-20 19:20:16 +00003198- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3199
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003200- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3201
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003202- Enhancements to the csv module:
3203
3204 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003205 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003206 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003207 + Dialect parameter parsing has been re-implemented to improve error
3208 reporting.
3209 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3210 dictates.
3211 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003212 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003213 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003214 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3215 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003216 + reader now allows \r characters to be quoted (previously it only allowed
3217 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003218 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003219 + Dialect classes passed to the module are no longer instantiated by
3220 the module before being parsed (the former validation scheme required
3221 this, but the mechanism was unreliable).
3222 + The dialect registry now contains instances of the internal
3223 C-coded dialect type, rather than references to python objects.
3224 + the internal c-coded dialect type is now immutable.
3225 + register_dialect now accepts the same keyword dialect specifications
3226 as the reader and writer, allowing the user to register dialects
3227 without first creating a dialect class.
3228 + a configurable limit to the size of parsed fields has been added -
3229 previously, an unmatched quote character could result in the entire
3230 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003231 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003232 the parser field size limit (returning the former limit). The initial
3233 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003234 + A line_num attribute has been added to the reader object, which tracks
3235 the number of lines read from the source iterator. This is not
3236 the same as the number of records returned, as records can span
3237 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003238 + reader and writer objects were not being registered with the cyclic-GC.
3239 This has been fixed.
3240
Brett Cannone6539c42005-01-08 02:43:53 +00003241- _DummyThread objects in the threading module now delete self.__block that is
3242 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3243 lock primitives tend to be limited in number and thus should not be wasted on
3244 a _DummyThread object. Fixes bug #1089632.
3245
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003246- The imghdr module now detects Exif files.
3247
Raymond Hettinger6065d322004-12-20 23:51:53 +00003248- StringIO.truncate() now correctly adjusts the size attribute.
3249 (Bug #951915).
3250
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003251- locale.py now uses an updated locale alias table (built using
3252 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3253 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003254 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003255
Raymond Hettinger3557f422004-12-07 12:02:02 +00003256- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3257
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003258- the pickle module no longer accepts the deprecated None option in the
3259 args tuple returned by __reduce__().
3260
Brett Cannon84667c02004-12-07 03:25:18 +00003261- optparse now optionally imports gettext. This allows its use in setup.py.
3262
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003263- the pickle module no longer uses the deprecated bin parameter.
3264
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003265- the shelve module no longer uses the deprecated binary parameter.
3266
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003267- the pstats module no longer uses the deprecated ignore() method.
3268
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003269- the filecmp module no longer uses the deprecated use_statcache argument.
3270
Raymond Hettinger664347b2004-12-04 21:21:53 +00003271- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3272 extended or overridden by subclasses. Formerly, the subclassed method would
3273 be ignored by the rest of the module. (Bug #1078905).
3274
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003275- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003276 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003277
Walter Dörwald36733692004-12-22 12:50:50 +00003278- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3279 once when a size argument is given. This prevents a buffer overflow in the
3280 tokenizer with very long source lines.
3281
Barry Warsaw538561e2006-01-01 21:48:54 +00003282- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3283 immediately after creating the object, without any intervening
3284 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003285
Skip Montanaro05885812005-01-16 20:48:27 +00003286- The reconvert.quote function can now emit triple-quoted strings. The
3287 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003288
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003289- ``UserString.MutableString`` now supports negative indices in
3290 ``__setitem__`` and ``__delitem__``
3291
Greg Ward40407942005-03-05 02:53:17 +00003292- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3293 correctly.
3294
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003295- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3296 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3297 character even if the user has passed a size parameter to get a proper
3298 line ending. Remove the special handling of a "\r\n" that has been split
3299 between two lines.
3300
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003301- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3302 about illegal code points. The codec now supports PEP 293 style error
3303 handlers.
3304
Walter Dörwald78a78b02005-09-01 12:04:29 +00003305- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003306 from the input stream, so that the output is a byte string in the correct
3307 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003308
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003309- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3310 considering it exactly like a '*'.
3311
Walter Dörwald007f8df2005-10-09 19:42:27 +00003312- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3313 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003314
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003315- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3316
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003317- Patch #1413711: Certain patterns of differences were making difflib
3318 touch the recursion limit.
3319
Walter Dörwald58917a62006-03-31 15:26:22 +00003320- Bug #947906: An object oriented interface has been added to the calendar
3321 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003322 called as a script (e.g. via ``python -mcalendar``). Localized month and
3323 weekday names can be ouput (even if an exotic encoding is used) using
3324 special classes that use unicode.

3327-----
3328
Neal Norwitz602d3392006-03-31 08:21:40 +00003329- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3330 by using -mieee gcc option.
3331

3333
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003334- Build support for Win64-AMD64 was added.
3335
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003336- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3337
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003338- Patch #881820: look for openpty and forkpty also in libbsd.
3339
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003340- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3341 The zlib module is now builtin on Windows.
3342
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003343- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3344
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003345- Bug #1189330: configure did not correctly determine the necessary
3346 value of LINKCC if python was built with GCC 4.0.
3347
Trent Mick8321b422005-07-26 02:29:21 +00003348- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3349 vulnerability in zlib 1.2.1 and 1.2.2.
3350
Brett Cannon08cd5982005-04-24 22:26:38 +00003351- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3352 flags that change binary compatibility. Changes were also made to
3353 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003354 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003355
Bob Ippolitoed233462005-03-29 13:47:59 +00003356- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3357 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3358 no longer exists). This configure patch makes things right.
3359
Martin v. Löwise2713be2005-03-08 15:03:08 +00003360- Bug #1158607: Build with --disable-unicode again.
3361
Brett Cannon46d96232005-02-16 00:07:19 +00003362- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3363 defined. Discovered as a result of not being able to build on OS X.
3364
Brett Cannon516592f2004-12-07 00:42:59 +00003365- setup.py now uses the directories specified in LDFLAGS using the -L option
3366 and in CPPFLAGS using the -I option for adding library and include
3367 directories, respectively, for compiling extension modules against. This has
3368 led to the core being compiled using the values in CPPFLAGS. It also removes
3369 the need for the special-casing of both DarwinPorts and Fink for darwin since
3370 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3371 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3372 Fink, ``-I/opt/local/include`` for DarwinPorts).
3373
Brett Cannon43802422005-02-10 20:48:03 +00003374- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3375 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3376 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3377 Closes bug #1096244. Thanks Gregory Bond.

Tim Petersc9d78aa2006-03-26 23:27:58 +00003382- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3383 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3384 is obtained via the ``PyObject_`` family, it must be released via the
3385 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3386 always been officially true, but when Python's small-object allocator was
3387 introduced, an attempt was made to cater to a few extension modules
3388 discovered at the time that obtained memory via ``PyObject_New`` but
3389 released it via ``PyMem_DEL``. It's years later, and if such code still
3390 exists it will fail now (probably with segfaults, but calling wrong
3391 low-level memory management functions can yield many symptoms).

Raymond Hettingerbeb31012005-08-16 03:47:52 +00003393- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003397- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3398 mapping argument now. This string is used as a mapping table. Byte values
3399 greater than the length of the string and 0xFFFE are treated as undefined
3400 mappings.
