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
Georg Brandl14404b62008-01-19 19:27:05 +000015- Issue #1679: "0x" was taken as a valid integer literal.
16
Christian Heimes288e89a2008-01-18 18:24:07 +000017- Issue #1865: Bytes as an alias for str and b"" as an alias "" were
18 added.
19
Christian Heimesc94e2b52008-01-14 04:13:37 +000020- sys.float_info / PyFloat_GetInfo: The floating point information
21 object was converted from a dict to a specialized structseq object.
22
Christian Heimesf31b69f2008-01-14 03:42:48 +000023- Patch #1816: Added sys.flags structseq. It exposes the status of most
24 command line arguments and PYTHON* environment variables.
25
26- Object/structseq.c: Implemented new structseq representation. The patch
27 makes structseqs (e.g. the return value of os.stat) more readable.
Christian Heimes9c201962008-01-14 03:33:52 +000028
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +000029- Patch #1700288: added a type attribute cache that caches method accesses,
30 resulting in speedups in heavily object-oriented code.
31
Neal Norwitz3fc15b82008-01-10 05:42:58 +000032- Bug #1776: __import__() no longer accepts filenames on any platform.
33 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +000034
Georg Brandlaed6c662008-01-07 17:25:53 +000035- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
36
Georg Brandl2da0fce2008-01-07 17:09:35 +000037- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE envvar
38 and sys.dont_write_bytecode attribute. All these can be set to forbid Python
39 to attempt to write compiled bytecode files.
40
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +000041- Improve some exception messages when Windows fails to load an extension
42 module. Now we get for example '%1 is not a valid Win32 application' instead
43 of 'error code 193'.
44
Christian Heimes8267d1d2008-01-04 00:37:34 +000045- Bug #1481296: Fixed long(float('nan'))!=0L.
46
Christian Heimeseebb79c2008-01-03 22:32:26 +000047- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x, y)
48 functions.
Christian Heimese2ca4242008-01-03 20:23:15 +000049
Christian Heimes0a8143f2007-12-18 23:22:54 +000050- Issue #1635: Platform independent creation and representation of NaN
51 and INF. float("nan"), float("inf") and float("-inf") now work on every
52 platform with IEEE 754 semantics.
53
Raymond Hettingerfd7ed402007-12-18 21:24:09 +000054- Compiler now generates simpler and faster code for dictionary literals.
55 The oparg for BUILD_MAP now indicates an estimated dictionary size.
56 There is a new opcode, STORE_MAP, for adding entries to the dictionary.
57
Christian Heimesdb3d6cb2007-12-16 21:39:43 +000058- Issue #1638: %zd configure test fails on Linux
59
Christian Heimes90e10e72007-12-14 02:35:23 +000060- Issue #1620: New property decorator syntax was modifying the decorator
61 in place instead of creating a new decorator object.
62
Christian Heimes284d9272007-12-10 22:28:56 +000063- Issue #1580: New free format floating point representation based on
64 "Floating-Point Printer Sample Code", by Robert G. Burger. For example
65 repr(11./5) now returns '2.2' instead of '2.2000000000000002'.
66
Skip Montanaro26015492007-12-08 15:33:24 +000067- Issue #1538: Avoid copying string in split/rsplit if the split
68 char is not found.
69
Andrew M. Kuchling395fe442007-12-05 13:27:20 +000070- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +000071 SystemError.
72
Nick Coghlanef01d822007-12-03 12:55:17 +000073- PEP 366: Allow explicit relative imports when executing modules
74 inside packages with the -m switch via a new module level
75 __package__ attribute.
76
Christian Heimesdfdfaab2007-12-01 11:20:10 +000077- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
78 ``PyFloat_GetInfo()`` to the float API.
79
Amaury Forgeot d'Arcdafd32b2007-11-30 20:51:40 +000080- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
81 format code incorrectly truncated the length to an int, even when
82 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
83 results with huge strings.
84
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +000085- Issue #1402: Fix a crash on exit, when another thread is still running, and
86 if the deallocation of its frames somehow calls the PyGILState_Ensure() /
87 PyGILState_Release() functions.
88
Christian Heimes28104c52007-11-27 23:16:44 +000089- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
90
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +000091- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
92 attribute of an empty cell object.
93
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +000094- Issue #1460: The utf-7 incremental decoder did not accept truncated input.
95 It now correctly saves its state between chunks of data.
96
Nick Coghlan327a39b2007-11-18 11:56:28 +000097- Patch #1739468: Directories and zipfiles containing a __main__.py file can
98 now be directly executed by passing their name to the interpreter. The
99 directory/zipfile is automatically inserted as the first entry in sys.path.
100
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +0000101- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
102 generator expression when at the same time the executed code is closing a
103 paused generator.
104
Raymond Hettinger1760c8a2007-11-08 02:52:43 +0000105- sets and frozensets now have an isdisjoint() method.
106
Raymond Hettinger3f8caa32007-10-24 01:28:33 +0000107- optimize the performance of builtin.sum().
108
Neal Norwitz44f326e2007-10-05 05:29:17 +0000109- Fix warnings found by the new version of the Coverity checker.
110
Raymond Hettinger8f669372007-10-03 21:18:11 +0000111- The enumerate() builtin function is no longer bounded to sequences smaller
112 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
113 shifts from ints to longs.
114
Brett Cannon0b14f242007-09-30 19:45:10 +0000115- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
116 having a self-referential tuple, which is possible from C code. Nor did
117 object's tp_str consider that a type's tp_str could do something that could
118 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
119 respectively, fixed the issues.
120
Brett Cannon01531592007-09-17 03:28:34 +0000121- Issue #1164: It was possible to trigger deadlock when using the 'print'
122 statement to write to a file since the GIL was not released as needed. Now
123 PyObject_Print() does the right thing along with various tp_print
124 implementations of the built-in types and those in the collections module.
125
Brett Cannon4c20bc42007-09-11 21:02:28 +0000126- Issue #1147: Exceptions were directly allowing string exceptions in their
127 throw() method even though string exceptions no longer allowed.
128
Brett Cannona0c05512007-09-10 21:38:27 +0000129- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
130 list by using the recursion counter.
131
Brett Cannon1e534b52007-09-07 04:18:30 +0000132- Issue #1202533: Fix infinite recursion calls triggered by calls to
133 PyObject_Call() never calling back out to Python code to trigger recursion
134 depth updates/checks. Required the creation of a static RuntimeError
135 instance in case normalizing an exception put the recursion check value past
136 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
137
Martin v. Löwisa5136192007-09-04 14:19:28 +0000138- Patch #1031213: Decode source line in SyntaxErrors back to its original source
139 encoding.
140

144 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
145 PyVarObject_HEAD_INIT.
146
Georg Brandl7c3b50d2007-07-12 08:38:00 +0000147- Patch #1673759: add a missing overflow check when formatting floats
148 with %G.
149
Martin v. Löwis6371cd82007-06-09 07:42:52 +0000150- Patch #1733960: Allow T_LONGLONG to accept ints.
151
Walter Dörwald84a3efe2007-06-13 16:57:12 +0000152- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
153
Neal Norwitzdb2b1b32007-06-11 07:36:24 +0000154- Prevent expandtabs() on string and unicode objects from causing a segfault
155 when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +0000156
Martin v. Löwisda587ab2007-06-08 17:29:20 +0000157- Bug #1733488: Fix compilation of bufferobject.c on AIX.
158
Georg Brandl25497a12007-06-01 19:20:27 +0000159- Bug #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +0000160
Neal Norwitz0ac60192007-05-27 04:08:54 +0000161- Add new attribute names for function objects. All the func_* become
162 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
163
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +0000164- Add -3 option to the interpreter to warn about features that are
165 deprecated and will be changed/removed in Python 3.0.
166
Georg Brandl2134e752007-05-21 20:34:16 +0000167- Patch #1686487: you can now pass any mapping after '**' in function
168 calls.
169
Collin Winter62903052007-05-18 23:11:24 +0000170- except clauses may now be spelled either "except E, target:" or
171 "except E as target:". This is to provide forwards compatibility with
172 Python 3.0.
173
Brett Cannon229cee22007-05-05 01:34:02 +0000174- Deprecate BaseException.message as per PEP 352.
175
Armin Rigo9790a272007-05-02 19:23:31 +0000176- Bug #1303614: don't expose object's __dict__ when the dict is
177 inherited from a builtin base.
178
Vinay Sajip8549ce32007-05-06 17:53:37 +0000179- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +0000180 setting a plain string, ie don't expand to single letter identifiers.
181
Raymond Hettinger13936692007-04-11 18:40:58 +0000182- Request #1191699: Slices can now be pickled.
183
Raymond Hettinger4db5fe92007-04-12 04:10:00 +0000184- Request #1193128: str.translate() now allows a None argument for
185 translations that only remove characters without re-mapping the
186 remaining characters.
187
Georg Brandl5cb76c12007-03-21 09:00:39 +0000188- Patch #1682205: a TypeError while unpacking an iterable is no longer
189 masked by a generic one with the message "unpack non-sequence".
190
Neal Norwitzaa754b72007-03-21 06:39:48 +0000191- Remove unused file Python/fmod.c.
192
Guido van Rossum143b5642007-03-23 04:58:42 +0000193- Bug #1683368: The object.__init__() and object.__new__() methods are
194 now stricter in rejecting excess arguments. The only time when
195 either allows excess arguments is when it is not overridden and the
196 other one is. For backwards compatibility, when both are
197 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +0000198 warning later). Also, type.__init__() insists on the same signature
199 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +0000200
Georg Brandl2b869942007-03-17 16:08:45 +0000201- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
202 to complex using its __complex__() method before falling back to the
203 __float__() method. Therefore, the functions in the cmath module now
204 can operate on objects that define a __complex__() method.
205
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +0000206- Patch #1623563: allow __class__ assignment for classes with __slots__.
207 The old and the new class are still required to have the same slot names.
208
Collin Winter77c67bd2007-03-16 04:11:30 +0000209- Patch #1642547: Fix an error/crash when encountering syntax errors in
210 complex if statements.
211
Žiga Seilnacht20f43d32007-03-15 11:44:55 +0000212- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
213 is called with an object that is faking its type.
214
Žiga Seilnacht71436f02007-03-14 12:24:09 +0000215- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
216 name.
217
Georg Brandl5240d742007-03-13 20:46:32 +0000218- Patch #1444529: the builtin compile() now accepts keyword arguments.
219
Georg Brandl7b9c5552007-03-12 14:30:05 +0000220- Bug #1678647: write a newline after printing an exception in any
221 case, even when converting the value to a string failed.
222
Georg Brandl871f1bc2007-03-12 13:17:36 +0000223- The dir() function has been extended to call the __dir__() method on
224 its argument, if it exists. If not, it will work like before. This allows
225 customizing the output of dir() in the presence of a __getattr__().
226
Collin Winter276887b2007-03-12 16:11:39 +0000227- Patch #922167: Python no longer segfaults when faced with infinitely
228 self-recursive reload() calls (as reported by bug #742342).
229
Žiga Seilnacht89032082007-03-11 15:54:54 +0000230- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
231
Collin Wintere38051d2007-03-09 20:33:07 +0000232- Patch #1491866: change the complex() constructor to allow parthensized
233 forms. This means complex(repr(x)) now works instead of raising a
234 ValueError.
235
Georg Brandlaa2321b2007-03-07 00:40:28 +0000236- Patch #703779: unset __file__ in __main__ after running a file. This
237 makes the filenames the warning module prints much more sensible when
238 a PYTHONSTARTUP file is used.
239
Georg Brandl49aafc92007-03-07 00:34:46 +0000240- Variant of patch #697613: don't exit the interpreter on a SystemExit
241 exception if the -i command line option or PYTHONINSPECT environment
242 variable is given, but break into the interactive interpreter just like
243 on other exceptions or normal program exit.
244
Georg Brandl00cd8182007-03-06 18:41:12 +0000245- Patch #1638879: don't accept strings with embedded NUL bytes in long().
246
Georg Brandl098cd692007-03-06 12:17:50 +0000247- Bug #1674503: close the file opened by execfile() in an error condition.
248
Georg Brandl0fca97a2007-03-05 22:28:08 +0000249- Patch #1674228: when assigning a slice (old-style), check for the
250 sq_ass_slice instead of the sq_slice slot.
251
Neal Norwitz88516a62007-02-26 22:41:45 +0000252- When printing an unraisable error, don't print exceptions. before the name.
253 This duplicates the behavior whening normally printing exceptions.
254
Martin v. Löwisfd963262007-02-09 12:19:32 +0000255- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
256
Brett Cannon129bd522007-01-30 21:34:36 +0000257- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
258 catch a string exception raises DeprecationWarning.
259
Brett Cannonf5bee302007-01-23 23:21:22 +0000260- Bug #1377858: Fix the segfaulting of the interpreter when an object created
261 a weakref on itself during a __del__ call for new-style classes (classic
262 classes still have the bug).
263
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000264- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
265 frame's thread state.
266
Thomas Wouters6ed19652007-01-23 13:50:49 +0000267- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
268
Martin v. Löwis4885e7d2007-01-19 06:42:22 +0000269- Bug #1637022: Prefix AST symbols with _Py_.
270
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000271- Prevent seg fault on shutdown which could occur if an object
272 raised a warning.
273
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000274- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
275 to avoid relying on atexit.
276
Raymond Hettinger94547f72006-12-20 06:42:06 +0000277- Bug #1590891: random.randrange don't return correct value for big number
278
Georg Brandl283a1352006-11-19 08:48:30 +0000279- Patch #1586791: Better exception messages for some operations on strings,
280 tuples and lists.
281
Martin v. Löwis056dac12006-11-12 18:24:26 +0000282- Bug #1067760: Deprecate passing floats to file.seek.

287
Georg Brandlb9f4ad32006-10-29 18:31:42 +0000288- Bug #1576657: when setting a KeyError for a tuple key, make sure that
289 the tuple isn't used as the "exception arguments tuple".
290
Neal Norwitz21997af2006-10-28 21:19:07 +0000291- Bug #1565514, SystemError not raised on too many nested blocks.

596
Georg Brandla09a96a2007-05-15 20:19:34 +0000597- HTML-escape the plain traceback in cgitb's HTML output, to prevent
598 the traceback inadvertently or maliciously closing the comment and
599 injecting HTML into the error page.
600
Neal Norwitz42dd86b2007-05-11 06:57:33 +0000601- The popen2 module and os.popen* are deprecated. Use the subprocess module.

Facundo Batistad918a652007-04-24 13:54:38 +0000618- As specified in RFC 2616, an HTTP response like 2xx indicates that
619 the client's request was successfully received, understood, and accepted.

Facundo Batista07c78be2007-03-23 18:54:07 +0000635
Martin v. Löwis0af33882007-03-23 13:27:15 +0000636- Bug #978833: Revert r50844, as it broke _socketobject.dup.

644 True (which is not the default), it visits symlinks pointing to
645 directories.
646
Georg Brandl8f06d022007-03-16 07:55:09 +0000647- Bug #1681228: the webbrowser module now correctly uses the default
648 GNOME or KDE browser, depending on whether there is a session of one

675
Georg Brandl8441f152007-03-13 20:02:57 +0000676- Patch #1530482: add pydoc.render_doc() which returns the documentation

Collin Winterfaaa2042007-03-10 03:35:34 +0000723 be equal to calling getsockname() on the server's socket. Fixed by
724 patch #1545011.
Collin Winter22c42ba2007-03-10 02:51:26 +0000725

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

780 import semantics.

1069 tuple, list, dict, set, and frozenset. Formerly, it would silently miscode
1070 subclasses of those types. Now, it raises a ValueError instead.

1086 time so that opening a database previously created with the DB_DUP or
1087 DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
1088 Specifically: dictionary assignment to a DB object will replace all
1089 values for a given key when the database allows duplicate values.
1090 DB users should use DB.put(k, v) when they want to store duplicates; not
1091 DB[k] = v.
1092
Gregory P. Smithac11e022007-11-05 02:56:31 +00001093- Add the bsddb.db.DBEnv.lock_id_free method.

1422-----------------
1423
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001424- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001425 compared equal or unequal to a string and a UnicodeDecodeError
1426 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001427
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001428 Instead, the equal (==) and unequal (!=) comparison operators will
1429 now issue a UnicodeWarning and interpret the two objects as
1430 unequal. The UnicodeWarning can be filtered as desired using
1431 the warning framework, e.g. silenced completely, turned into an
1432 exception, logged, etc.
1433
1434 Note that compare operators other than equal and unequal will still
1435 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001436

1445- Patch #1538606, Fix __index__() clipping. There were some problems
1446 discovered with the API and how integers that didn't fit into Py_ssize_t
1447 were handled. This patch attempts to provide enough alternatives
1448 to effectively use __index__.
1449
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001450- Bug #1536021: __hash__ may now return long int; the final hash
1451 value is obtained by invoking hash on the long int.
1452
Thomas Hellerab1049c2006-08-08 17:37:00 +00001453- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1454
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001455- Bug #1535165: fixed a segfault in input() and raw_input() when
1456 sys.stdin is closed.
1457
Thomas Heller74d36f02006-08-04 18:17:40 +00001458- On Windows, the PyErr_Warn function is now exported from
1459 the Python dll again.
1460
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001461- Bug #1191458: tracing over for loops now produces a line event
1462 on each iteration. Fixing this problem required changing the .pyc
1463 magic number. This means that .pyc files generated before 2.5c1
1464 will be regenerated.
1465
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001466- Bug #1333982: string/number constants were inappropriately stored
1467 in the byte code and co_consts even if they were not used, ie
1468 immediately popped off the stack.
1469
Georg Brandle9462c72006-08-04 18:03:37 +00001470- Fixed a reference-counting problem in property().

1473Library
1474-------
1475
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001476- Fix a bug in the ``compiler`` package that caused invalid code to be
1477 generated for generator expressions.
1478
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001479- The distutils version has been changed to 2.5.0. The change to
1480 keep it programmatically in sync with the Python version running
1481 the code (introduced in 2.5b3) has been reverted. It will continue
1482 to be maintained manually as static string literal.
1483
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001484- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001485 and this cannot be converted to the required C type, an exception is
1486 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001487 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001488
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001489- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001490 an exception.
1491
Tim Petersc10c9d02006-09-05 02:18:09 +00001492- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001493 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001494 workarounds for clocks with low resolution, to stop the code yielding
1495 duplicate UUIDs.
1496
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001497- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1498 before raising SystemExit, allowing IDLE to honor quit() and exit().
1499
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001500- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1501
Georg Brandl7a1af772006-08-14 21:55:28 +00001502- Patch #1536071: trace.py should now find the full module name of a
1503 file correctly even on Windows.
1504
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001505- logging's atexit hook now runs even if the rest of the module has
1506 already been cleaned up.
1507
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001508- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001509
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001510- Bug #1531405, format_exception no longer raises an exception if
1511 str(exception) raised an exception.
1512
Neil Schemenauer06ded092006-08-04 16:20:30 +00001513- Fix a bug in the ``compiler`` package that caused invalid code to be
1514 generated for nested functions.

1521
Georg Brandl3335a7a2006-08-14 21:42:55 +00001522- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1523 raises the correct exceptions.
1524
Thomas Heller1ce433e2006-08-14 16:20:04 +00001525- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1526 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1527
Thomas Heller86720042006-08-14 11:17:48 +00001528- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1529 uses the _as_parameter_ attribute when objects are passed to foreign
1530 function calls. The ctypes version number was changed to 1.0.1.
1531
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001532- Bug #1530559, struct.pack raises TypeError where it used to convert.
1533 Passing float arguments to struct.pack when integers are expected
1534 now triggers a DeprecationWarning.
1535
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001536

1559
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001560- Bug #1535502, build _hashlib on Windows, and use masm assembler
1561 code in OpenSSL.
1562
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001563- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.
1564
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001565- Bug #1530448, ctypes build failure on Solaris 10 was fixed.
Thomas Heller17984892006-08-04 18:57:34 +00001566
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001567
Tim Peters4643c2f2006-08-10 22:45:34 +00001568C API
1569-----
1570
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001571- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1572
Tim Peters4643c2f2006-08-10 22:45:34 +00001573- Bug #1069160. Internal correctness changes were made to
1574 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1575 the documentation was changed to state that the return value
1576 is always 1 (normal) or 0 (if the specified thread wasn't found).

Neal Norwitza1f10902006-07-12 07:28:29 +00001581
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001582*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001583
1584Core and builtins
1585-----------------
1586
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001587- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001588 returned a long (see PEP 353).
1589
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001590- Bug #1515471: string.replace() accepts character buffers again.
1591
Neal Norwitz07aadb12006-07-30 06:55:48 +00001592- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1593 This provides the proper warning for struct.pack().
1594 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1595
Neal Norwitz0d62a062006-07-30 06:53:31 +00001596- Patch #1531113: Fix augmented assignment with yield expressions.
1597 Also fix a SystemError when trying to assign to yield expressions.
1598
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001599- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1600 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1601 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1602 excessive filesystem operations during imports.
1603
Tim Petersbc24eee2006-07-27 01:14:53 +00001604- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1605 operations on signed longs that are formally undefined by C.
1606 Unfortunately, at least one compiler now cares about that, so complicated
1607 the code to make that compiler happy again.
1608
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001609- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1610
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001611- Patch #1232023: Stop including current directory in search
1612 path on Windows.
1613
Neal Norwitze1fdb322006-07-21 05:32:28 +00001614- Fix some potential crashes found with failmalloc.
1615
Neal Norwitze7563102006-07-17 01:00:16 +00001616- Fix warnings reported by Klocwork's static analysis tool.
1617
Neal Norwitz84be93b2006-07-16 01:50:38 +00001618- Bug #1512814, Fix incorrect lineno's when code within a function
1619 had more than 255 blank lines.
1620
Georg Brandl9dceedb2006-07-12 15:31:17 +00001621- Patch #1521179: Python now accepts the standard options ``--help`` and
1622 ``--version`` as well as ``/?`` on Windows.
1623
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001624- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001625 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001626 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001627
Tim Peters112aad32006-07-19 00:03:19 +00001628- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001629 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001630 new ``sys._current_frames()`` returns a dictionary with one entry,
1631 mapping the faux "thread id" 0 to the current frame.
1632
Ronald Oussoren3075e162006-07-25 20:28:55 +00001633- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001634
Ronald Oussoren3075e162006-07-25 20:28:55 +00001635
Neal Norwitza1f10902006-07-12 07:28:29 +00001636Library
1637-------
1638
Facundo Batista6e22be72008-01-19 18:45:46 +00001639- Fix #1693149. Now you can pass several modules separated by
1640 comma to trace.py in the same --ignore-module option.
1641
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001642- Correction of patch #1455898: In the mbcs decoder, set final=False
1643 for stream decoder, but final=True for the decode function.
1644
Georg Brandl07fec3a2006-08-01 18:49:24 +00001645- os.urandom no longer masks unrelated exceptions like SystemExit or
1646 KeyboardInterrupt.
1647
Tim Peters4643c2f2006-08-10 22:45:34 +00001648- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001649 shutil.copytree on Windows
1650
Georg Brandle34ac7c2006-07-30 11:07:23 +00001651- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1652 refers to file descriptors, not file objects.
1653
Tim Petersc10c9d02006-09-05 02:18:09 +00001654- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001655 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001656 #1513611, and probably others.
1657
Georg Brandledd9b0d2006-07-29 09:33:26 +00001658- Bug #1441397: The compiler module now recognizes module and function
1659 docstrings correctly as it did in Python 2.4.
1660
Tim Peters6f681472006-07-27 23:44:37 +00001661- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1662 lost that tests are sorted by name before being run. This rarely
1663 matters for well-written tests, but can create baffling symptoms if
1664 side effects from one test to the next affect outcomes. ``DocTestFinder``
1665 has been changed to sort the list of tests it returns.
1666
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001667- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001668 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001669
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001670- Bug #978833: Really close underlying socket in _socketobject.close.
1671
Georg Brandl8c036cc2006-08-20 13:15:39 +00001672- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1673 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001674
Georg Brandlcf0c1722006-07-26 07:23:32 +00001675- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1676 to recursive calls and call it with the failing package name.
1677
Martin v. Löwis0b483032006-07-25 09:53:12 +00001678- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1679
Georg Brandlc13c34c2006-07-24 14:09:56 +00001680- Patch #1515343: Fix printing of deprecated string exceptions with a
1681 value in the traceback module.
1682
Greg Ward48fae7a2006-07-23 16:05:51 +00001683- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1684
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001685- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1686
Brett Cannoncaebe222006-07-18 04:41:36 +00001687- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1688 argument tuple. For arguments where zero is illegal, the value is forced to
1689 the minimum value that is correct. This is to support an undocumented but
1690 common way people used to fill in inconsequential information in the time
1691 tuple pre-2.4.
1692
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001693- Patch #1220874: Update the binhex module for Mach-O.
1694
Barry Warsawb110bad2006-07-21 14:51:07 +00001695- The email package has improved RFC 2231 support, specifically for
1696 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1697 (name*0=<blah>) parameter continuations. This may change the types of
1698 values returned from email.message.Message.get_param() and friends.
1699 Specifically in some cases where non-encoded continuations were used,
1700 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1701 will just return the string (since non-encoded continuations don't have
1702 charset and language parts).
1703
1704 Also, whereas % values were decoded in all parameter continuations, they are
1705 now only decoded in encoded parameter parts.
1706
Ronald Oussoren3075e162006-07-25 20:28:55 +00001707- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1708
1709- Bug #1517996: IDLE now longer shows the default Tk menu when a
1710 path browser, class browser or debugger is the frontmost window on MacOS X
1711
Barry Warsaw00decd72006-07-27 23:43:15 +00001712- Patch #1520294: Support for getset and member descriptors in types.py,
1713 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1714 of an object against these built-in types and more importantly, for getting
1715 their docstrings printed in the interactive interpreter's help() function.

1719-----------------
1720
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001721- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1722 a socket operation on a socket with a timeout, the exception will be
1723 caught correctly. Previously, the exception was not caught.
1724
Thomas Heller1393d6a2006-07-28 21:43:20 +00001725- Patch #1529514: The _ctypes extension is now compiled on more
1726 openbsd target platforms.
1727
Tim Peters9cab5932006-07-28 00:30:00 +00001728- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1729 a memory leak, affecting pickles and deep copies.
1730
Tim Petersbc24eee2006-07-27 01:14:53 +00001731- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001732 Paul Eggert.
1733
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001734- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1735
Thomas Hellerce049a02006-07-14 17:51:14 +00001736- Patch #1521817: Index range checking on ctypes arrays containing
1737 exactly one element enabled again. This allows iterating over these
1738 arrays, without the need to check the array size before.
1739
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001740- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001741 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001742 /dev/null in certain cases; this is now fixed.
1743
Thomas Heller47d7a062006-07-12 08:43:47 +00001744- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1745 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001746
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001747- Because of a misspelled preprocessor symbol, ctypes was always
1748 compiled without thread support; this is now fixed.
1749
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001750- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1751 methods now allow their database parameter to be None as the
1752 sleepycat API allows.
1753
Matt Flemingec926502006-07-28 11:27:27 +00001754- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1755 bluetooth API compared with Linux and FreeBSD.
1756
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001757Tests
1758-----
1759
1760- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1761 how long the test file should take to play. Now accepts taking 2.93 secs
1762 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1763
Georg Brandl4793aa32006-07-28 18:31:39 +00001764- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1765 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1766 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001773Mac
1774---
1775
1776- PythonLauncher now works correctly when the path to the script contains
1777 characters that are treated specially by the shell (such as quotes).
1778
1779- Bug #1527397: PythonLauncher now launches scripts with the working directory
1780 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001781 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001782 expect.

1790Core and builtins
1791-----------------
1792
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001793- Bug #1441486: The literal representation of -(sys.maxint - 1)
1794 again evaluates to a int object, not a long.
1795
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001796- Bug #1501934: The scope of global variables that are locally assigned
1797 using augmented assignment is now correctly determined.
1798
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001799- Bug #927248: Recursive method-wrapper objects can now safely
1800 be released.
1801
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001802- Bug #1417699: Reject locale-specific decimal point in float()
1803 and atof().
1804
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001805- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1806 omit a default "error" argument for NULL pointer. This allows
1807 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001808
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001809- Bug #1519018: 'as' is now validated properly in import statements.
1810
Neal Norwitz28746ab2006-07-09 22:14:42 +00001811- On 64 bit systems, int literals that use less than 64 bits are
1812 now ints rather than longs.
1813
Neal Norwitzed657552006-07-10 00:04:44 +00001814- Bug #1512814, Fix incorrect lineno's when code at module scope
1815 started after line 256.
1816
Tim Peters32a83612006-07-10 21:08:24 +00001817- New function ``sys._current_frames()`` returns a dict mapping thread
1818 id to topmost thread stack frame. This is for expert use, and is
1819 especially useful for debugging application deadlocks. The functionality
1820 was previously available in Fazal Majid's ``threadframe`` extension
1821 module, but it wasn't possible to do this in a wholly threadsafe way from
1822 an extension.
1823

1828 VS 2003.
1829
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001830- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1831
Tim Peters32a83612006-07-10 21:08:24 +00001832- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001833 environment variable to be set in order to the SDK environment
1834 for finding the compiler, include files, etc.

1839
Thomas Woutersadd19112006-07-05 11:03:49 +00001840- string.Template() now correctly handles tuple-values. Previously,
1841 multi-value tuples would raise an exception and single-value tuples would
1842 be treated as the value they contain, instead.
1843
Martin v. Löwisede77f52006-07-03 13:01:35 +00001844- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1846
Martin v. Löwis45482392006-07-03 12:28:58 +00001847- Bug #1267547: Put proper recursive setup.py call into the
1848 spec file generated by bdist_rpm.
1849
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001850- Bug #1514693: Update turtle's heading when switching between
1851 degrees and radians.
1852
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001853- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001854 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001855
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001856- Bug #1514703: Only setup canvas window in turtle when the canvas
1857 is created.
1858
Martin v. Löwis7596e832006-07-01 15:33:37 +00001859- Bug #1513223: .close() of a _socketobj now releases the underlying
1860 socket again, which then gets closed as it becomes unreferenced.

1863 attribute values.
1864
1865- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1866 sgmllib ('[' and ']' were not accepted).
1867
Georg Brandl1be63af2006-06-28 20:23:25 +00001868- Fix a bug in the turtle module's end_fill function.
1869
Brett Cannon53ab5b72006-06-22 16:49:14 +00001870- Bug #1510580: The 'warnings' module improperly required that a Warning
1871 category be either a types.ClassType and a subclass of Warning. The proper
1872 check is just that it is a subclass with Warning as the documentation states.
1873
Georg Brandlad29e632006-06-21 17:45:17 +00001874- The compiler module now correctly compiles the new try-except-finally
1875 statement (bug #1509132).
1876
Neal Norwitz60373cd2006-06-22 06:30:50 +00001877- The wsgiref package is now installed properly on Unix.
1878
Vinay Sajip28e57612006-07-01 10:45:20 +00001879- A bug was fixed in logging.config.fileConfig() which caused a crash on
1880 shutdown when fileConfig() was called multiple times.
1881
Gerhard Häring762fbd32006-07-02 17:48:30 +00001882- The sqlite3 module did cut off data from the SQLite database at the first
1883 null character before sending it to a custom converter. This has been fixed
1884 now.
1885
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001886Extension Modules
1887-----------------
1888
Tim Peters112aad32006-07-19 00:03:19 +00001889- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1890 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1891 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001892
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001893- Assigning None to pointer type fields in ctypes structures possible
1894 overwrote the wrong fields, this is fixed now.
1895
1896- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1897 on non-Windows platforms.
1898
1899- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1900 integer or long, without range checking.
1901
1902- Patch #1517790: It is now possible to use custom objects in the ctypes
1903 foreign function argtypes sequence as long as they provide a from_param
1904 method, no longer is it required that the object is a ctypes type.
1905
1906- The '_ctypes' extension module now works when Python is configured
1907 with the --without-threads option.
1908
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001909- Bug #1513646: os.access on Windows now correctly determines write
1910 access, again.
1911
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001912- Bug #1512695: cPickle.loads could crash if it was interrupted with
1913 a KeyboardInterrupt.
1914
Neal Norwitza12aa882006-07-06 06:45:08 +00001915- Bug #1296433: parsing XML with a non-default encoding and
1916 a CharacterDataHandler could crash the interpreter in pyexpat.
1917
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001918- Patch #1516912: improve Modules support for OpenVMS.

1921-----
1922
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001923- Automate Windows build process for the Win64 SSL module.
1924
Tim Peters32a83612006-07-10 21:08:24 +00001925- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001926 Previously, the slight difference could cause compilation errors of the
1927 'zlib' module on systems with more than one version of zlib.
1928
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001929- The MSI compileall step was fixed to also support a TARGETDIR
1930 with spaces in it.
1931
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001932- Bug #1517388: sqlite3.dll is now installed on Windows independent

1948 documentation for the warnings module.
1949
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001950- Patch #1509163: MS Toolkit Compiler no longer available.

1960Core and builtins
1961-----------------
1962
Georg Brandla56b9152006-06-19 06:35:54 +00001963- Patch #1507676: Error messages returned by invalid abstract object operations
1964 (such as iterating over an integer) have been improved and now include the
1965 type of the offending object to help with debugging.
1966
Brett Cannonea3912b2006-06-13 21:46:41 +00001967- Bug #992017: A classic class that defined a __coerce__() method that returned
1968 its arguments swapped would infinitely recurse and segfault the interpreter.
1969
Neal Norwitz909eb122006-06-12 02:13:21 +00001970- Fix the socket tests so they can be run concurrently.
1971
Neal Norwitzb9845e72006-06-12 02:11:18 +00001972- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001973 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001974
Brett Cannon22565aa2006-06-09 22:31:23 +00001975- Bug #532646: object.__call__() will continue looking for the __call__
1976 attribute on objects until one without one is found. This leads to recursion
1977 when you take a class and set its __call__ attribute to an instance of the
1978 class. Originally fixed for classic classes, but this fix is for new-style.
1979 Removes the infinite_rec_3 crasher.
1980
Georg Brandl24250812006-06-09 18:45:48 +00001981- The string and unicode methods startswith() and endswith() now accept
1982 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1983
Brett Cannonde3b0522006-06-08 17:00:45 +00001984- Buffer objects, at the C level, never used the char buffer
1985 implementation even when the char buffer for the wrapped object was
1986 explicitly requested (originally returned the read or write buffer).
1987 Now a TypeError is raised if the char buffer is not present but is
1988 requested.
1989
Georg Brandlddbaa662006-06-04 21:56:52 +00001990- Patch #1346214: Statements like "if 0: suite" are now again optimized
1991 away like they were in Python 2.4.
1992
Georg Brandlb7c8f542006-05-27 12:30:25 +00001993- Builtin exceptions are now full-blown new-style classes instead of
1994 instances pretending to be classes, which speeds up exception handling
1995 by about 80% in comparison to 2.5a2.
1996
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001997- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1998 Unicode 4.1.
1999
Georg Brandlf4ef1162006-05-26 18:03:31 +00002000- Patch #921466: sys.path_importer_cache is now used to cache valid and
2001 invalid file paths for the built-in import machinery which leads to
2002 fewer open calls on startup.
2003
Tim Peters696cf432006-05-24 21:10:40 +00002004- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
2005 of-2 bases. The largest speedup is for inputs with about 1000 decimal
2006 digits. Conversion from non-power-of-2 bases remains quadratic-time in
2007 the number of input digits (it was and remains linear-time for bases
2008 2, 4, 8, 16 and 32).
2009
Tim Petersb713ec22006-05-23 18:45:30 +00002010- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
2011 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
2012 an integer close to ``sys.maxint``. This was repaired by patch
2013 #1335972, which also gives a nice speedup.
2014
Richard Jonescebbefc2006-05-23 18:28:17 +00002015- Patch #1337051: reduced size of frame objects.
2016
2017- PyErr_NewException now accepts a tuple of base classes as its
2018 "base" parameter.
2019
Richard Jones7c88dcc2006-05-23 10:37:38 +00002020- Patch #876206: function call speedup by retaining allocated frame
2021 objects.
2022
Georg Brandl7b90e162006-05-18 07:01:27 +00002023- Bug #1462152: file() now checks more thoroughly for invalid mode
2024 strings and removes a possible "U" before passing the mode to the
2025 C library function.
2026
Neal Norwitz1004a532006-05-15 07:17:23 +00002027- Patch #1488312, Fix memory alignment problem on SPARC in unicode
2028
Neal Norwitz373f0a72006-05-15 07:04:36 +00002029- Bug #1487966: Fix SystemError with conditional expression in assignment
2030
Martin v. Löwis879768d2006-05-11 13:28:43 +00002031- WindowsError now has two error code attributes: errno, which carries
2032 the error values from errno.h, and winerror, which carries the error
2033 values from winerror.h. Previous versions put the winerror.h values
2034 (from GetLastError()) into the errno attribute.
2035
Martin v. Löwis77736712006-05-04 05:51:03 +00002036- Patch #1475845: Raise IndentationError for unexpected indent.
2037
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00002038- Patch #1479181: split open() and file() from being aliases for each other.
2039
Tim Peters44bd9862006-06-01 13:49:23 +00002040- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
2041 methods were always silently ignored by dictionaries when comparing keys.
2042 They are now passed through (except when using the C API function
2043 ``PyDict_GetItem()``, whose semantics did not change).
2044
2045- Bug #1456209: In some obscure cases it was possible for a class with a
2046 custom ``__eq__()`` method to confuse dict internals when class instances
2047 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
2048 No, you don't have any code that did this ;-)

2051-----------------
2052
Trent Mick960a3f82006-06-28 20:30:41 +00002053- Bug #1295808: expat symbols should be namespaced in pyexpat
2054
2055- Patch #1462338: Upgrade pyexpat to expat 2.0.0
2056
Brett Cannon6ee7d012006-06-08 16:23:04 +00002057- Change binascii.hexlify to accept a read-only buffer instead of only a char
2058 buffer and actually follow its documentation.
2059
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00002060- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
2061
Nick Coghlanc649ec52006-05-29 12:43:05 +00002062- Patch #1478788 (modified version): The functional extension module has
2063 been renamed to _functools and a functools Python wrapper module added.
2064 This provides a home for additional function related utilities that are
2065 not specifically about functional programming. See PEP 309.
2066
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00002067- Patch #1493701: performance enhancements for struct module.
2068
Georg Brandl378d5922006-05-17 14:26:50 +00002069- Patch #1490224: time.altzone is now set correctly on Cygwin.
2070
Georg Brandl8d3342b2006-05-16 07:38:27 +00002071- Patch #1435422: zlib's compress and decompress objects now have a
2072 copy() method.
2073
Andrew MacIntyre92913322006-06-13 15:04:24 +00002074- Patch #1454481: thread stack size is now tunable at runtime for thread
2075 enabled builds on Windows and systems with Posix threads support.
2076
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002077- On Win32, os.listdir now supports arbitrarily-long Unicode path names
2078 (up to the system limit of 32K characters).
2079
2080- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
2081 As a result, these functions now raise WindowsError instead of OSError.
2082
Tim Peters7a822da2006-05-25 21:50:17 +00002083- ``time.clock()`` on Win64 should use the high-performance Windows
2084 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
2085 Windows platforms).
2086
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002087- Calling Tk_Init twice is refused if the first call failed as that
2088 may deadlock.
2089
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00002090- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
2091 accept it without potentially using an uninitialized pointer.
2092
2093- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
2094 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
2095 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00002096
Gregory P. Smith372b5832006-06-05 18:48:21 +00002097- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00002098 [pybsddb project SF patch number 1466734]
2099
Gregory P. Smith372b5832006-06-05 18:48:21 +00002100- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
2101 parameter is supplied. [SF pybsddb bug #1477863]
2102
Gregory P. Smith3c228b12006-06-05 23:59:37 +00002103- bsddb: the __len__ method of a DB object has been fixed to return correct
2104 results. It could previously incorrectly return 0 in some cases.
2105 Fixes SF bug 1493322 (pybsddb bug 1184012).
2106
Gregory P. Smithff7d9912006-06-08 05:17:08 +00002107- bsddb: the bsddb.dbtables Modify method now raises the proper error and
2108 aborts the db transaction safely when a modifier callback fails.
2109 Fixes SF python patch/bug #1408584.
2110
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002111- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00002112 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002113 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
2114 database calls that would previously deadlock. [SF python bug #775414]
2115
Vinay Sajip28e57612006-07-01 10:45:20 +00002116- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00002117
Walter Dörwald4994d952006-06-19 08:07:50 +00002118- Patch #1506645: add Python wrappers for the curses functions
2119 is_term_resized, resize_term and resizeterm.

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00002124- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
2125 functions.
2126
Martin v. Löwis3798da02006-06-17 18:44:27 +00002127- Patch #812986: Update turtle output even if not tracing.
2128
Vinay Sajip28e57612006-07-01 10:45:20 +00002129- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00002130 Tkinter.BaseWidget.
2131
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00002132- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
2133
Martin v. Löwis337487e2006-06-17 09:15:14 +00002134- Patch #763580: Add name and value arguments to Tkinter variable
2135 classes.
2136
Georg Brandl83cc0d02006-06-14 08:50:03 +00002137- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
2138 mime.types file for determining MIME types.
2139
Georg Brandl2605ca82006-06-14 06:08:31 +00002140- Bug #1339007: Shelf objects now don't raise an exception in their
2141 __del__ method when initialization failed.
2142
Martin v. Löwisd8251432006-06-14 05:21:04 +00002143- Patch #1455898: The MBCS codec now supports the incremental mode for
2144 double-byte encodings.
2145
Tim Peters43898b42006-06-14 04:09:25 +00002146- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2147 guarantee that adjacent triples in the return list always describe
2148 non-adjacent blocks. Previously, a pair of matching blocks could end
2149 up being described by multiple adjacent triples that formed a partition
2150 of the matching pair.
2151
Greg Ward0e0c9f42006-06-11 16:24:11 +00002152- Bug #1498146: fix optparse to handle Unicode strings in option help,
2153 description, and epilog.
2154
Greg Wardd1c797e2006-06-11 14:42:41 +00002155- Bug #1366250: minor optparse documentation error.
2156
Greg Ward7f547402006-06-11 00:40:49 +00002157- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
2158 clarify docs.
2159
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002160- The wsgiref package has been added to the standard library.
2161
Nick Coghlan676725d2006-06-08 13:54:49 +00002162- The functions update_wrapper() and wraps() have been added to the functools
2163 module. These make it easier to copy relevant metadata from the original
2164 function when writing wrapper functions.
2165
Tim Petersd6a9eef2006-06-05 01:48:21 +00002166- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2167 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002168
Martin v. Löwis3f767792006-06-04 19:36:28 +00002169- Patch #1359618: Speed up charmap encoder by using a trie structure
2170 for lookup.
2171
Tim Petersd609b1a2006-06-02 23:22:51 +00002172- The functions in the ``pprint`` module now sort dictionaries by key
2173 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2174 if and only if its display required more than one line, although that
2175 wasn't documented. The new behavior increases predictability; e.g.,
2176 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2177
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002178- Patch #1497027: try HTTP digest auth before basic auth in urllib2
2179 (thanks for J. J. Lee).
2180
Georg Brandl2b330372006-05-28 20:23:12 +00002181- Patch #1496206: improve urllib2 handling of passwords with respect to
2182 default HTTP and HTTPS ports.
2183
George Yoshidaf3c65de2006-05-28 16:39:09 +00002184- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
2185
Bob Ippolito7298f272006-05-23 18:43:47 +00002186- Patch #1281707: speed up gzip.readline.
2187
Georg Brandlb89316f2006-05-17 15:51:16 +00002188- Patch #1180296: Two new functions were added to the locale module:
2189 format_string() to get the effect of "format % items" but locale-aware,
2190 and currency() to format a monetary number with currency sign.
2191
Georg Brandle3a25832006-05-17 14:56:04 +00002192- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2193 and several features added, such as speed and geometry control.
2194
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002195- Patch #1488881: add support for external file objects in bz2 compressed
2196 tarfiles.
2197
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002198- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2199 stdout arguments, making it possible to redirect input and output
2200 for remote debugging.
2201
2202- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2203 a couple of issues, notably handling of long file names using the
2204 GNU LONGNAME extension.
2205
2206- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2207 new flag when ``name`` is already the name of an option flag.
2208
2209- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2210 package.
2211
2212- Patch #1472854: make the rlcompleter.Completer class usable on non-
2213 UNIX platforms.
2214
2215- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
2216
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00002217- Bug #1472827: correctly escape newlines and tabs in attribute values in
2218 the saxutils.XMLGenerator class.

2253Core and builtins
2254-----------------
2255
Thomas Heller1b046642006-04-18 18:51:06 +00002256- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2257 by converting these apis from macros into exported functions again:
2258
2259 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2260 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2261 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2262 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2263 PyRun_String Py_CompileString
2264
Martin v. Löwis45294a92006-04-18 06:24:08 +00002265- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2266
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002267- All uses of PyStructSequence_InitType have been changed to initialize
2268 the type objects only once, even if the interpreter is initialized
2269 multiple times.
2270
Neal Norwitz61546162006-04-14 05:20:28 +00002271- Bug #1454485, array.array('u') could crash the interpreter. This was
2272 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2273 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2274
2275- Py_UNICODE is unsigned. It was always documented as unsigned, but
2276 due to a bug had a signed value in previous versions.
2277
Tim Peters3a5e8b12006-04-11 01:44:07 +00002278- Patch #837242: ``id()`` of any Python object always gives a positive
2279 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2280 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002281 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002282 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002283
Tim Peters3a5e8b12006-04-11 01:44:07 +00002284 def __hash__(self):
2285 return id(self) # WRONG
2286
2287 because a hash result must be a (short) Python int but it was always
2288 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002289 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002290 was always usable as a hash value before this patch. That's no longer
2291 necessarily so.
2292
2293- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002294 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002295 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002296 #1454844)
2297
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002298- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2299 involving generators that have paused outside of any ``try`` or ``with``
2300 blocks. (In 2.5a1, a paused generator that was part of a reference
2301 cycle could not be garbage collected, regardless of whether it was
2302 paused in a ``try`` or ``with`` block.)

Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002310- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2311 fails with an error condition.
2312
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002313- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2314
2315- Bug #1117761: bsddb.*open() no longer raises an exception when using
2316 the cachesize parameter.
2317
2318- Bug #1149413: bsddb.*open() no longer raises an exception when using
2319 a temporary db (file=None) with the 'n' flag to truncate on open.
2320
2321- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2322 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002323
Armin Rigoa9017c32006-04-19 11:50:27 +00002324- Patch #1062014: AF_UNIX sockets under Linux have a special

2329
Peter Astrand7d1d4362006-07-14 14:04:45 +00002330- Bug #1223937: subprocess.CalledProcessError reports the exit status
2331 of the process using the returncode attribute, instead of
2332 abusing errno.
2333
Tim Peters711bf302006-04-25 03:31:36 +00002334- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2335 a doctest to be skipped (the code is not run, and the expected output
2336 or exception is ignored).
2337
Nick Coghlanda2268f2006-04-24 04:37:15 +00002338- Fixed contextlib.nested to cope with exceptions being raised and
2339 caught inside exit handlers.
2340
Greg Wardab05edc2006-04-23 03:47:58 +00002341- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2342 hex, octal, or binary; add ``append_const`` action; keep going if
2343 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2344 added ``epilog`` for better help generation).
2345
Tim Peters21fbd572006-04-21 21:18:10 +00002346- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2347 called from a thread spawned as a side effect of importing a module.
2348
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002349- The pydoc module now supports documenting packages contained in
2350 .zip or .egg files.
2351
2352- The pkgutil module now has several new utility functions, such
2353 as ``walk_packages()`` to support working with packages that are either
2354 in the filesystem or zip files.
2355
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002356- The mailbox module can now modify and delete messages from
2357 mailboxes, in addition to simply reading them. Thanks to Gregory
2358 K. Johnson for writing the code, and to the 2005 Google Summer of
2359 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002360
Tim Petersc7605f22006-04-17 21:12:33 +00002361- The ``__del__`` method of class ``local`` in module ``_threading_local``

2369
Anthony Baxtere29002c2006-04-12 12:07:31 +00002370- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2371 Windows. Bug #1469163.
2372
Phillip J. Eby47032112006-04-11 01:07:43 +00002373- The warnings, linecache, inspect, traceback, site, and doctest modules
2374 were updated to work correctly with modules imported from zipfiles or
2375 via other PEP 302 __loader__ objects.
2376
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002377- Patch #1467770: Reduce usage of subprocess._active to processes which

Skip Montanaro262fb922006-04-21 02:31:07 +00002384- The pstats.Stats class accepts an optional stream keyword argument to
2385 direct output to an alternate file-like object.
2386
Anthony Baxter51bcb682006-04-05 14:51:42 +00002387Build
2388-----
2389
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002390- The Makefile now has a reindent target, which runs reindent.py on
2391 the library.
2392
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002393- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002396
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002397- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2398 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002399 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002400 CXX from --with-cxx-main, see description in README.
2401
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002402- Patch #1429775: Link extension modules with the shared libpython.
2403
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002404- Fixed a libffi build problem on MIPS systems.
2405
Tim Peters8931ff12006-05-13 23:28:20 +00002406- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2407 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2408 and "%zu" for unsigned integers of type ``size_t``.
2409
Anthony Baxter51bcb682006-04-05 14:51:42 +00002410Tests
2411-----
2412
Nick Coghlanda2268f2006-04-24 04:37:15 +00002413- test_contextlib now checks contextlib.nested can cope with exceptions
2414 being raised and caught inside exit handlers.
2415
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002416- test_cmd_line now checks operation of the -m and -c command switches
2417
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002418- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2419 it separately and by hand. It also wasn't cleaning up its changes to
2420 the current Decimal context.
2421
Thomas Woutersabd08882006-04-26 15:53:30 +00002422- regrtest.py now has a -M option to run tests that test the new limits of
2423 containers, on 64-bit architectures. Running these tests is only sensible
2424 on 64-bit machines with more than two gigabytes of memory. The argument
2425 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002433Documentation
2434-------------
2435
Tim Petersb06d28c2006-05-12 01:57:59 +00002436- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2437
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002438- PEP 343: Added Context Types section to the library reference
2439 and attempted to bring other PEP 343 related documentation into
2440 line with the implementation and/or python-dev discussions.
2441
Tim Peters8dc73d22006-04-24 02:03:16 +00002442- Bug #1337990: clarified that ``doctest`` does not support examples
2443 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +00002444

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002446What's New in Python 2.5 alpha 1?
2447=================================
2448
Anthony Baxterebed3f62006-04-03 15:03:44 +00002449*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002450
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002451Core and builtins
2452-----------------
2453
Nick Coghlan43832302006-04-23 17:04:07 +00002454- PEP 338: -m command line switch now delegates to runpy.run_module
2455 allowing it to support modules in packages and zipfiles
2456
Martin v. Löwisc661b882006-04-20 04:54:23 +00002457- On Windows, .DLL is not an accepted file name extension for
2458 extension modules anymore; extensions are only found if they
2459 end in .PYD.
2460
Martin v. Löwisea62d252006-04-03 10:56:49 +00002461- Bug #1421664: sys.stderr.encoding is now set to the same value as
2462 sys.stdout.encoding.
2463
Neal Norwitz92e212f2006-04-03 04:48:37 +00002464- __import__ accepts keyword arguments.
2465
Georg Brandlccadf842006-03-31 18:54:53 +00002466- Patch #1460496: round() now accepts keyword arguments.
2467
Anthony Baxter262c00a2006-03-30 10:53:17 +00002468- Fixed bug #1459029 - unicode reprs were double-escaped.
2469
Hye-Shik Changd478f342006-03-23 12:32:36 +00002470- Patch #1396919: The system scope threads are reenabled on FreeBSD
2471 5.4 and later versions.
2472
Neal Norwitze98ccf62006-03-23 05:39:47 +00002473- Bug #1115379: Compiling a Unicode string with an encoding declaration
2474 now gives a SyntaxError.
2475
Georg Brandlabd1ff82006-03-18 07:59:59 +00002476- Previously, Python code had no easy way to access the contents of a
2477 cell object. Now, a ``cell_contents`` attribute has been added
2478 (closes patch #1170323).
2479
Tim Peterscf79aac2006-03-16 01:14:46 +00002480- Patch #1123430: Python's small-object allocator now returns an arena to
2481 the system ``free()`` when all memory within an arena becomes unused
2482 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2483 freed. Some applications will see a drop in virtual memory size now,
2484 especially long-running applications that, from time to time, temporarily
2485 use a large number of small objects. Note that when Python returns an
2486 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002487 platform C library will in turn return that memory to the operating system.
2488 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002489 appears to be effective at least on Microsoft C and gcc-based systems.
2490 Thanks to Evan Jones for hard work and patience.
2491
Georg Brandl533ff6f2006-03-08 18:09:27 +00002492- Patch #1434038: property() now uses the getter's docstring if there is
2493 no "doc" argument given. This makes it possible to legitimately use
2494 property() as a decorator to produce a read-only property.
2495
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002496- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2497 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2498 of requiring an int or long in slicing and a few other contexts, enabling
2499 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2500
Neal Norwitz995acdf2006-03-07 05:01:00 +00002501- Fixed various bugs reported by Coverity's Prevent tool.
2502
Brett Cannonbf364092006-03-01 04:25:17 +00002503- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2504 new exception base class, BaseException, which has a new message attribute.
2505 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2506 Raising a string exception now raises a DeprecationWarning.
2507
Thomas Woutersfb609f42006-02-28 16:37:25 +00002508- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2509 explicitly relative, using 'from .module import name' to mean 'from the same
2510 package as this module is in. Imports without dots still default to the
2511 old relative-then-absolute, unless 'from __future__ import
2512 absolute_import' is used.
2513
Brett Cannona7446e32006-02-27 23:39:10 +00002514- Properly check if 'warnings' raises an exception (usually when a filter set
2515 to "error" is triggered) when raising a warning for raising string
2516 exceptions.
2517
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002518- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002519 The name was removed from Include/code.h.
2520
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002521- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002522
Guido van Rossum1968ad32006-02-25 22:38:04 +00002523- Patch 1433928:
2524 - The copy module now "copies" function objects (as atomic objects).
2525 - dict.__getitem__ now looks for a __missing__ hook before raising
2526 KeyError.
2527
Tim Peters84ef21c2006-02-28 20:39:06 +00002528- PEP 343: with statement implemented. Needs ``from __future__ import
2529 with_statement``. Use of 'with' as a variable will generate a warning.
2530 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002531 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002532 The following objects have __context__ methods:
2533 - The built-in file type.
2534 - The thread.LockType type.
2535 - The following types defined by the threading module:
2536 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2537 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002538
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002539- Fix the encodings package codec search function to only search
2540 inside its own package. Fixes problem reported in patch #1433198.
2541
2542 Note: Codec packages should implement and register their own
2543 codec search function. PEP 100 has the details.
2544
Tim Peters9ea89d22006-06-04 03:26:02 +00002545- PEP 353: Using ``Py_ssize_t`` as the index type.
2546
2547- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2548 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2549 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2550 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2551 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002552
Neal Norwitzfc76d632006-01-10 06:03:13 +00002553- Patch #1400181, fix unicode string formatting to not use the locale.
2554 This is how string objects work. u'%f' could use , instead of .
2555 for the decimal point. Now both strings and unicode always use periods.
2556
Neal Norwitz671b9e32006-01-09 07:07:12 +00002557- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2558 configure would break checking curses.h.
2559
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002560- Bug #959576: The pwd module is now builtin. This allows Python to be
2561 built on UNIX platforms without $HOME set.
2562
Neal Norwitzc10978f2005-12-19 06:07:16 +00002563- Bug #1072182, fix some potential problems if characters are signed.
2564
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002565- Bug #889500, fix line number on SyntaxWarning for global declarations.
2566
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002567- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2568
Neal Norwitze7214a12005-12-18 05:03:17 +00002569- Support for converting hex strings to floats no longer works.
2570 This was not portable. float('0x3') now raises a ValueError.
2571
Barry Warsaw2a38a862005-12-18 01:27:35 +00002572- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002573 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002574 is now displayed in interactive prompt banner.
2575
Georg Brandlfa166682005-12-17 21:45:17 +00002576- Implementation of PEP 341 - Unification of try/except and try/finally.
2577 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002578 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002579
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002580- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2581 now encodes backslash correctly.
2582
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002583- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2584
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002585- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002586 and long longs.
2587
Neal Norwitz67715f02005-11-09 06:59:35 +00002588- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002589 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002590 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002591
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002592- Replaced most Unicode charmap codecs with new ones using the
2593 new Unicode translate string feature in the builtin charmap
2594 codec; the codecs were created from the mapping tables available
2595 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2596 encodings now include a mapping for the Apple logo)
2597
Tim Peterse3547fd2005-12-16 23:13:57 +00002598- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002599
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002600- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002601
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002602- A new AST parser implementation was completed. The abstract
2603 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002604 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002605
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002606- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002607 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2608
Neal Norwitz708e51a2005-10-03 04:48:15 +00002609- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2610
Neal Norwitz11bd1192005-10-03 00:54:56 +00002611- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2612 Provide a warning when a directory is passed on the command line.
2613
Neal Norwitz40d37812005-10-02 01:48:49 +00002614- Fix segfault with invalid coding.
2615
2616- SF bug #772896: unknown encoding results in MemoryError.
2617
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002618- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002619 supported a __len__() method which evaluated to False when the iterator
2620 was empty.
2621
Guido van Rossum630db602005-09-20 18:49:54 +00002622- On 64-bit platforms, when __len__() returns a value that cannot be
2623 represented as a C int, raise OverflowError.
2624
Skip Montanarof8948ca2005-09-19 03:54:46 +00002625- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002626 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002627
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002628- SF bug #893549: parsing keyword arguments was broken with a few format
2629 codes.
2630
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002631- Changes donated by Elemental Security to make it work on AIX 5.3
2632 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2633 bug #105470: test_pwd fails on 64bit system (Opteron).
2634
Guido van Rossum539c6622005-09-14 17:49:54 +00002635- Changes donated by Elemental Security to make it work on HP-UX 11 on
2636 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2637
Georg Brandl4550b8d2005-08-26 06:43:52 +00002638- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002639 (fixes bug #1119418).
2640
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002641- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2642
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002643- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2644 exceptions that cause a function to exit.
2645
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002646- The implementation of set() and frozenset() was revised to use its
2647 own internal data structure. Memory consumption is reduced by 1/3
2648 and there are modest speed-ups as well. The API is unchanged.
2649
Tim Petersde7990b2005-07-17 23:45:23 +00002650- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2651
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002652- SF bug #1229429: PyObject_CallMethod failed to decrement some
2653 reference counts in some error exit cases.
2654
Tim Petersecc6e6a2005-07-10 22:30:55 +00002655- SF bug #1185883: Python's small-object memory allocator took over
2656 a block managed by the platform C library whenever a realloc specified
2657 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002658 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002659 portable way to copy data from the C-managed block into Python's
2660 small-object space without risking a memory fault. Python's small-object
2661 realloc now leaves such blocks under the control of the platform C
2662 realloc.
2663
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002664- SF bug #1232517: An overflow error was not detected properly when
2665 attempting to convert a large float to an int in os.utime().
2666
Raymond Hettinger3296e692005-06-29 23:29:56 +00002667- SF bug #1224347: hex longs now print with lowercase letters just
2668 like their int counterparts.
2669
Michael W. Hudson188d4362005-06-20 16:52:57 +00002670- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2671 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2672 interpreter states; back out that fix and do a better job (see
2673 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2674 for a longer write-up of the problem).
2675
Michael W. Hudsondf888462005-06-03 14:41:55 +00002676- SF patch #1180995: marshal now uses a binary format by default when
2677 serializing floats.
2678
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002679- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2680 the routines that promise to produce IEEE 754 binary representations
2681 of floats now simply copy bytes around.
2682
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002683- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2684 278.
2685
Brett Cannonc3647ac2005-04-26 03:45:26 +00002686- patch #1109424: int, long, float, complex, and unicode now check for the
2687 proper magic slot for type conversions when subclassed. Previously the
2688 magic slot was ignored during conversion. Semantics now match the way
2689 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002690 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002691 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002692 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002693
Barry Warsawc8d907c2005-04-19 23:43:40 +00002694- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2695 NULL, now raise an AttributeError when attempting to set or delete the
2696 attribute. Previously a TypeError was raised, but this was inconsistent
2697 with the equivalent pure-Python implementation.
2698
Michael W. Hudson774479c2005-04-18 08:46:17 +00002699- It is now safe to call PyGILState_Release() before
2700 PyEval_InitThreads() (note that if there is reason to believe there
2701 are multiple threads around you still must call PyEval_InitThreads()
2702 before using the Python API; this fix is for extension modules that
2703 have no way of knowing if Python is multi-threaded yet).
2704
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002705- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2706 disabled caused a crash.
2707
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002708- Bug #1165306: instancemethod_new allowed the creation of a method
2709 with im_class == im_self == NULL, which caused a crash when called.
2710
Tim Petersecc6e6a2005-07-10 22:30:55 +00002711- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002712 fixes the crash seen in bug #1165761
2713
Raymond Hettinger96229b12005-03-11 06:49:40 +00002714- Added two new builtins, any() and all().
2715
Brett Cannon409d8f22005-03-05 06:47:57 +00002716- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002717 (e.g., ``class C(): pass`` is no longer a syntax error).
2718 Patch #1176012 added support to the 'parser' module and 'compiler' package
2719 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002720
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002721- Patch #1115086: Support PY_LONGLONG in structmember.
2722
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002723- Bug #1155938: new style classes did not check that __init__() was
2724 returning None.
2725
Tim Petersecc6e6a2005-07-10 22:30:55 +00002726- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002727 ('\') with a specific error message.
2728
Martin v. Löwisff232d72005-03-03 09:24:38 +00002729- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2730
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002731- Bug #1124295: the __name__ attribute of file objects was
2732 inadvertently made inaccessible in restricted mode.
2733
Tim Petersecc6e6a2005-07-10 22:30:55 +00002734- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002735 an ferror() call.
2736
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002737- min() and max() now support key= arguments with the same meaning as in
2738 list.sort().
2739
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002740- The peephole optimizer now performs simple constant folding in expressions:
2741 (2+3) --> (5).
2742
Raymond Hettingera422c342005-01-11 03:03:27 +00002743- set and frozenset objects can now be marshalled. SF #1098985.
2744
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002745- Bug #1077106: Poor argument checking could cause memory corruption
2746 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002747
Jeremy Hyltonab630502005-02-04 18:44:06 +00002748- The parser did not complain about future statements in illegal
2749 positions. It once again reports a syntax error if a future
2750 statement occurs after anything other than a doc string.
2751
Neil Schemenauercf52c072005-08-12 17:34:58 +00002752- Change the %s format specifier for str objects so that it returns a
2753 unicode instance if the argument is not an instance of basestring and
2754 calling __str__ on the argument returns a unicode instance.
2755
Tim Petersf4e69282006-02-27 17:15:31 +00002756- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2757 current thread state when the auto-GIL-state machinery knows about
2758 it (since the thread state is being deleted, continuing to remember it
2759 can't help, but can hurt if another thread happens to get created with
2760 the same thread id).
2761
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002762Extension Modules
2763-----------------
2764

Neal Norwitz10be10c2006-03-16 06:50:13 +00002778 util, whatsound, whrandom, zmod
2779
2780- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2781
2782- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002783 is deprecated. The undocumented re.engine variable no longer exists.
2784
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002785- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2786 SS2 (single-shift 2) escape sequences correctly.
2787
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002788- The unicodedata module was updated to the 4.1 version of the Unicode
2789 database. The 3.2 version is still available as unicodedata.db_3_2_0
2790 for applications that require this specific version (such as IDNA).
2791
Neal Norwitzb62c4332006-03-04 18:35:47 +00002792- The timing module is no longer built by default. It was deprecated
2793 in PEP 4 in Python 2.0 or earlier.
2794
Guido van Rossum1968ad32006-02-25 22:38:04 +00002795- Patch 1433928: Added a new type, defaultdict, to the collections module.
2796 This uses the new __missing__ hook behavior added to dict (see above).
2797
Georg Brandldbd83392006-02-20 09:42:33 +00002798- Bug #854823: socketmodule now builds on Sun platforms even when
2799 INET_ADDRSTRLEN is not defined.
2800
Georg Brandlf4f44152006-02-18 22:29:33 +00002801- Patch #1393157: os.startfile() now has an optional argument to specify
2802 a "command verb" to invoke on the file.
2803
Neal Norwitz082b2df2006-02-07 07:04:46 +00002804- Bug #876637, prevent stack corruption when socket descriptor

2806
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002807- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2808 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2809 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

2812 than the system default domain.
2813
Martin v. Löwis14694662006-02-03 12:54:16 +00002814- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2815 are reported, the limit on path name lengths is removed, and stat reports
2816 WindowsError now (instead of OSError).
2817
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002818- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2893 the request code argument, which results in more C-like behaviour
2894 for large or negative values.
2895
Tim Petersecc6e6a2005-07-10 22:30:55 +00002896- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2911
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00002912- operator.itemgetter() and operator.attrgetter() now support retrieving

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002936- the cPickle module no longer accepts the deprecated None option in the
2937 args tuple returned by __reduce__().
2938
Raymond Hettingerb2594052004-12-05 09:25:51 +00002939- itertools.islice() now accepts None for the start and step arguments.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002952- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2953 been renamed to have only a single underscore prefix. This was done to
2954 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002955
Nick Coghlan43832302006-04-23 17:04:07 +00002956- PEP 338: new module runpy defines a run_module function to support
2957 executing modules which provide access to source code or a code object
2958 via the PEP 302 import mechanisms.
2959
Anthony Baxter93f5b932006-04-03 08:05:07 +00002960- The email module's parsedate_tz function now sets the daylight savings

2968 in attribute values.
2969
Anthony Baxterc51ee692006-04-01 00:57:31 +00002970- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002971 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002972 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002973 module will not be built.
2974
Tim Petersc17976e2006-04-01 00:26:53 +00002975- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2976 aren't officially supported here, and trying to use them will probably
2977 raise an exception some day. But dicts have been allowed, and "mostly
2978 worked", so support for them won't go away without warning.
2979
Georg Brandl338ef7d2006-03-31 18:42:16 +00002980- Bug #1445068: getpass.getpass() can now be given an explicit stream
2981 argument to specify where to write the prompt.
2982
Georg Brandl22ec80b2006-03-31 18:25:44 +00002983- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2990
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002991- Queue.Queue objects now support .task_done() and .join() methods
2992 to make it easier to monitor when daemon threads have completed
2993 processing all enqueued tasks. Patch #1455676.
2994
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002995- popen2.Popen objects now preserve the command in a .cmd attribute.

2998
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002999- email 4.0 package now integrated. This is largely the same as the email 3.0
3000 package that was included in Python 2.3, except that PEP 8 module names are
3001 now used (e.g. mail.message instead of email.Message). The MIME classes
3002 have been moved to a subpackage (e.g. email.mime.text instead of
3003 email.MIMEText). The old names are still supported for now. Several
3004 deprecated Message methods have been removed and lots of bugs have been
3005 fixed. More details can be found in the email package documentation.
3006
Walter Dörwald40108c92006-03-27 08:15:44 +00003007- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
3008 (a subclass of tuple) that provides incremental decoders and encoders
3009 (a way to use stateful codecs without the stream API). Python functions
3010 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
3011 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
3012 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00003013
Walter Dörwald067db482006-03-15 22:17:27 +00003014- Patch #1359365: Calling next() on a closed StringIO.String object raises
3015 a ValueError instead of a StopIteration now (like file and cString.String do).
3016 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
3017 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00003018
Martin v. Löwis04824ce2006-03-10 21:26:16 +00003019- A regrtest option -w was added to re-run failed tests in verbose mode.

3029
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00003030- PEP 343: new module contextlib.py defines decorator @contextmanager
3031 and helpful context managers nested() and closing().
3032
Martin v. Löwis415ed932006-02-27 19:56:30 +00003033- The compiler package now supports future imports after the module docstring.
3034

Martin v. Löwis3e865952006-01-24 15:51:21 +00003067 specifications, raises IOErrors when proxies for unsupported protocols
3068 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00003091 SHA1, 224, 256, 384, and 512. Note that recent developments make the
3092 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
3093 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
3094 Ronald L. Rivest offered this advice for Python:
3095
3096 "The consensus of researchers in this area (at least as
3097 expressed at the NIST Hash Function Workshop 10/31/05),
3098 is that SHA-256 is a good choice for the time being, but
3099 that research should continue, and other alternatives may
3100 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00003101
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00003102- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandlb9256022005-08-24 18:46:39 +00003148- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
3149 ContentTooShortException, when the actually downloaded size does not
3150 match the Content-Length header.
3151
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +00003152- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
3153
Martin v. Löwis56066d22005-08-24 07:38:12 +00003154- Bug #1178484: Return complete lines from codec stream readers
3155 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00003156 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00003157

3171
Georg Brandla4a8b822005-07-15 09:13:21 +00003172- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
3173 parameter, but uses the usual "kwargs=None".
3174
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003175- textwrap now processes text chunks at O(n) speed instead of O(n**2).

3177
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00003178- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
3179 to W3C name (404 -> 'Not Found'). RFE #1216944.
3180
Georg Brandl9e43acf2005-07-04 17:16:07 +00003181- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
3182 as this can cause problems with apps closing all file descriptors.
3183
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00003184- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003185 it can be missing in embedded interpreters

Raymond Hettingerda99d1c2005-06-21 07:43:58 +00003194- The tokenize module now detects and reports indentation errors.
3195 Bug #1224621.
3196
Raymond Hettinger68c04532005-06-10 11:05:19 +00003197- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00003198 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00003199 the generate_tokens() function now accepts a callable argument that
3200 terminates by raising StopIteration.
3201
Georg Brandl9166e1a2005-06-04 09:20:03 +00003202- Bug #1196315: fix weakref.WeakValueDictionary constructor.
3203
Georg Brandl268e61c2005-06-03 14:28:50 +00003204- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
3205 component of the path.
3206
Skip Montanaro174dd222005-05-14 20:54:16 +00003207- Patch #1120353: The xmlrpclib module provides better, more transparent,
3208 support for datetime.{datetime,date,time} objects. With use_datetime set
3209 to True, applications shouldn't have to fiddle with the DateTime wrapper
3210 class at all.
3211
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00003212- distutils.commands.upload was added to support uploading distribution
3213 files to PyPI.
3214
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00003215- distutils.commands.register now encodes the data as UTF-8 before posting
3216 them to PyPI.
3217
Raymond Hettinger267b8682005-03-27 10:47:39 +00003218- decimal operator and comparison methods now return NotImplemented
3219 instead of raising a TypeError when interacting with other types. This
3220 allows other classes to implement __radd__ style methods and have them
3221 work as expected.
3222
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003223- Bug #1163325: Decimal infinities failed to hash. Attempting to
3224 hash a NaN raised an InvalidOperation instead of a TypeError.
3225
Tim Petersecc6e6a2005-07-10 22:30:55 +00003226- Patch #918101: Add tarfile open mode r|* for auto-detection of the

3260
Guido van Rossumd0641422005-02-03 15:01:24 +00003261- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3262 disables recursive traversal through instance attributes, which can
3263 be exploited in various ways.
3264
Tim Peterse3547fd2005-12-16 23:13:57 +00003265- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003266 flags on the HTTP listening socket.
3267
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003268- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3269 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3270
Fred Drakefbdeaad2006-07-29 16:56:15 +00003271- Patches #893642, #1039083: add allow_none, encoding arguments to
3272 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003273
Martin v. Löwis1d11de62005-01-29 13:29:23 +00003274- Bug #1110478: Revert os.environ.update to do putenv again.
3275
Thomas Hellerd6c6e222005-01-20 19:20:16 +00003276- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3277
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003278- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3279
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003280- Enhancements to the csv module:
3281
3282 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003283 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003284 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003285 + Dialect parameter parsing has been re-implemented to improve error
3286 reporting.
3287 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3288 dictates.
3289 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003290 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003291 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003292 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3293 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003294 + reader now allows \r characters to be quoted (previously it only allowed
3295 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003296 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003297 + Dialect classes passed to the module are no longer instantiated by
3298 the module before being parsed (the former validation scheme required
3299 this, but the mechanism was unreliable).
3300 + The dialect registry now contains instances of the internal
3301 C-coded dialect type, rather than references to python objects.
3302 + the internal c-coded dialect type is now immutable.
3303 + register_dialect now accepts the same keyword dialect specifications
3304 as the reader and writer, allowing the user to register dialects
3305 without first creating a dialect class.
3306 + a configurable limit to the size of parsed fields has been added -
3307 previously, an unmatched quote character could result in the entire
3308 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003309 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003310 the parser field size limit (returning the former limit). The initial
3311 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003312 + A line_num attribute has been added to the reader object, which tracks
3313 the number of lines read from the source iterator. This is not
3314 the same as the number of records returned, as records can span
3315 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003316 + reader and writer objects were not being registered with the cyclic-GC.
3317 This has been fixed.
3318
Brett Cannone6539c42005-01-08 02:43:53 +00003319- _DummyThread objects in the threading module now delete self.__block that is
3320 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3321 lock primitives tend to be limited in number and thus should not be wasted on
3322 a _DummyThread object. Fixes bug #1089632.
3323
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003324- The imghdr module now detects Exif files.
3325
Raymond Hettinger6065d322004-12-20 23:51:53 +00003326- StringIO.truncate() now correctly adjusts the size attribute.
3327 (Bug #951915).
3328
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003329- locale.py now uses an updated locale alias table (built using
3330 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3331 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003332 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003333
Raymond Hettinger3557f422004-12-07 12:02:02 +00003334- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3335
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003336- the pickle module no longer accepts the deprecated None option in the
3337 args tuple returned by __reduce__().
3338
Brett Cannon84667c02004-12-07 03:25:18 +00003339- optparse now optionally imports gettext. This allows its use in setup.py.
3340
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003341- the pickle module no longer uses the deprecated bin parameter.
3342
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003343- the shelve module no longer uses the deprecated binary parameter.
3344
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003345- the pstats module no longer uses the deprecated ignore() method.
3346
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003347- the filecmp module no longer uses the deprecated use_statcache argument.
3348
Raymond Hettinger664347b2004-12-04 21:21:53 +00003349- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3350 extended or overridden by subclasses. Formerly, the subclassed method would
3351 be ignored by the rest of the module. (Bug #1078905).
3352
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003353- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003354 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003355
Walter Dörwald36733692004-12-22 12:50:50 +00003356- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3357 once when a size argument is given. This prevents a buffer overflow in the
3358 tokenizer with very long source lines.
3359
Barry Warsaw538561e2006-01-01 21:48:54 +00003360- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3361 immediately after creating the object, without any intervening
3362 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003363
Skip Montanaro05885812005-01-16 20:48:27 +00003364- The reconvert.quote function can now emit triple-quoted strings. The
3365 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003366
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003367- ``UserString.MutableString`` now supports negative indices in
3368 ``__setitem__`` and ``__delitem__``
3369
Greg Ward40407942005-03-05 02:53:17 +00003370- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3371 correctly.
3372
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003373- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3374 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3375 character even if the user has passed a size parameter to get a proper
3376 line ending. Remove the special handling of a "\r\n" that has been split
3377 between two lines.
3378
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003379- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3380 about illegal code points. The codec now supports PEP 293 style error
3381 handlers.
3382
Walter Dörwald78a78b02005-09-01 12:04:29 +00003383- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003384 from the input stream, so that the output is a byte string in the correct
3385 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003386
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003387- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3388 considering it exactly like a '*'.
3389
Walter Dörwald007f8df2005-10-09 19:42:27 +00003390- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3391 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003392
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003393- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3394
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003395- Patch #1413711: Certain patterns of differences were making difflib
3396 touch the recursion limit.
3397
Walter Dörwald58917a62006-03-31 15:26:22 +00003398- Bug #947906: An object oriented interface has been added to the calendar
3399 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003400 called as a script (e.g. via ``python -mcalendar``). Localized month and
3401 weekday names can be ouput (even if an exotic encoding is used) using
3402 special classes that use unicode.

3411
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003412- Build support for Win64-AMD64 was added.
3413
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003414- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3415
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003416- Patch #881820: look for openpty and forkpty also in libbsd.
3417
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003418- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3419 The zlib module is now builtin on Windows.
3420
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003421- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3422
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003423- Bug #1189330: configure did not correctly determine the necessary
3424 value of LINKCC if python was built with GCC 4.0.
3425
Trent Mick8321b422005-07-26 02:29:21 +00003426- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3427 vulnerability in zlib 1.2.1 and 1.2.2.
3428
Brett Cannon08cd5982005-04-24 22:26:38 +00003429- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3430 flags that change binary compatibility. Changes were also made to
3431 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003432 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003433
Bob Ippolitoed233462005-03-29 13:47:59 +00003434- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3435 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3436 no longer exists). This configure patch makes things right.
3437
Martin v. Löwise2713be2005-03-08 15:03:08 +00003438- Bug #1158607: Build with --disable-unicode again.
3439
Brett Cannon46d96232005-02-16 00:07:19 +00003440- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3441 defined. Discovered as a result of not being able to build on OS X.
3442
Brett Cannon516592f2004-12-07 00:42:59 +00003443- setup.py now uses the directories specified in LDFLAGS using the -L option
3444 and in CPPFLAGS using the -I option for adding library and include
3445 directories, respectively, for compiling extension modules against. This has
3446 led to the core being compiled using the values in CPPFLAGS. It also removes
3447 the need for the special-casing of both DarwinPorts and Fink for darwin since
3448 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3449 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3450 Fink, ``-I/opt/local/include`` for DarwinPorts).
3451
Brett Cannon43802422005-02-10 20:48:03 +00003452- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3453 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3454 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3455 Closes bug #1096244. Thanks Gregory Bond.

3458-----
3459
Tim Petersc9d78aa2006-03-26 23:27:58 +00003460- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3461 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3462 is obtained via the ``PyObject_`` family, it must be released via the
3463 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3464 always been officially true, but when Python's small-object allocator was
3465 introduced, an attempt was made to cater to a few extension modules
3466 discovered at the time that obtained memory via ``PyObject_New`` but
3467 released it via ``PyMem_DEL``. It's years later, and if such code still
3468 exists it will fail now (probably with segfaults, but calling wrong
3469 low-level memory management functions can yield many symptoms).
3470
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003471- Added a C API for set and frozenset objects.
3472
Raymond Hettinger66517482004-12-03 11:45:13 +00003473- Removed PyRange_New().
3474
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003475- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3476 mapping argument now. This string is used as a mapping table. Byte values
3477 greater than the length of the string and 0xFFFE are treated as undefined
3478 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003485
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003486- Patch #1276356: New resource "urlfetch" is implemented. This enables
3487 even impatient people to run tests that require remote files.
