12Core and builtins
13-----------------
14
Georg Brandl32a3fb52008-01-21 21:23:15 +000015- Patch #1720595: add T_BOOL to the range of structmember types.
16
Georg Brandl26543b12008-01-21 18:36:51 +000017- Issue #1882: when compiling code from a string, encoding cookies in the
18 second line of code were not always recognized correctly.
19
Georg Brandl14404b62008-01-19 19:27:05 +000020- Issue #1679: "0x" was taken as a valid integer literal.
21
Christian Heimes288e89a2008-01-18 18:24:07 +000022- Issue #1865: Bytes as an alias for str and b"" as an alias "" were
23 added.
24
Christian Heimesc94e2b52008-01-14 04:13:37 +000025- sys.float_info / PyFloat_GetInfo: The floating point information
26 object was converted from a dict to a specialized structseq object.
27
Christian Heimesf31b69f2008-01-14 03:42:48 +000028- Patch #1816: Added sys.flags structseq. It exposes the status of most
Vinay Sajip2bdc48c2008-01-21 18:16:05 +000029 command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +000030
31- Object/structseq.c: Implemented new structseq representation. The patch
32 makes structseqs (e.g. the return value of os.stat) more readable.
Christian Heimes9c201962008-01-14 03:33:52 +000033
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +000034- Patch #1700288: added a type attribute cache that caches method accesses,
35 resulting in speedups in heavily object-oriented code.
36
Neal Norwitz3fc15b82008-01-10 05:42:58 +000037- Bug #1776: __import__() no longer accepts filenames on any platform.

Georg Brandlaed6c662008-01-07 17:25:53 +000040- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
41
Georg Brandl2da0fce2008-01-07 17:09:35 +000042- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE envvar
43 and sys.dont_write_bytecode attribute. All these can be set to forbid Python
44 to attempt to write compiled bytecode files.
45
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +000046- Improve some exception messages when Windows fails to load an extension
47 module. Now we get for example '%1 is not a valid Win32 application' instead
48 of 'error code 193'.
49
Christian Heimes8267d1d2008-01-04 00:37:34 +000050- Bug #1481296: Fixed long(float('nan'))!=0L.
51
Christian Heimeseebb79c2008-01-03 22:32:26 +000052- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x, y)
53 functions.

57 platform with IEEE 754 semantics.
58
Raymond Hettingerfd7ed402007-12-18 21:24:09 +000059- Compiler now generates simpler and faster code for dictionary literals.
60 The oparg for BUILD_MAP now indicates an estimated dictionary size.
61 There is a new opcode, STORE_MAP, for adding entries to the dictionary.
62
Christian Heimesdb3d6cb2007-12-16 21:39:43 +000063- Issue #1638: %zd configure test fails on Linux
64
Christian Heimes90e10e72007-12-14 02:35:23 +000065- Issue #1620: New property decorator syntax was modifying the decorator
66 in place instead of creating a new decorator object.
67
Christian Heimes284d9272007-12-10 22:28:56 +000068- Issue #1580: New free format floating point representation based on
69 "Floating-Point Printer Sample Code", by Robert G. Burger. For example
70 repr(11./5) now returns '2.2' instead of '2.2000000000000002'.
71
Skip Montanaro26015492007-12-08 15:33:24 +000072- Issue #1538: Avoid copying string in split/rsplit if the split
73 char is not found.
74
Andrew M. Kuchling395fe442007-12-05 13:27:20 +000075- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +000076 SystemError.
77
Nick Coghlanef01d822007-12-03 12:55:17 +000078- PEP 366: Allow explicit relative imports when executing modules
79 inside packages with the -m switch via a new module level
80 __package__ attribute.
81
Christian Heimesdfdfaab2007-12-01 11:20:10 +000082- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
83 ``PyFloat_GetInfo()`` to the float API.
84
Amaury Forgeot d'Arcdafd32b2007-11-30 20:51:40 +000085- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
86 format code incorrectly truncated the length to an int, even when
87 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
88 results with huge strings.
89
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +000090- Issue #1402: Fix a crash on exit, when another thread is still running, and
91 if the deallocation of its frames somehow calls the PyGILState_Ensure() /
92 PyGILState_Release() functions.
93
Christian Heimes28104c52007-11-27 23:16:44 +000094- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
95
Vinay Sajip2bdc48c2008-01-21 18:16:05 +000096- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +000097 attribute of an empty cell object.
98
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +000099- Issue #1460: The utf-7 incremental decoder did not accept truncated input.
100 It now correctly saves its state between chunks of data.
101
Nick Coghlan327a39b2007-11-18 11:56:28 +0000102- Patch #1739468: Directories and zipfiles containing a __main__.py file can
103 now be directly executed by passing their name to the interpreter. The
104 directory/zipfile is automatically inserted as the first entry in sys.path.
105
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +0000106- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
107 generator expression when at the same time the executed code is closing a
108 paused generator.
109
Raymond Hettinger1760c8a2007-11-08 02:52:43 +0000110- sets and frozensets now have an isdisjoint() method.
111
Raymond Hettinger3f8caa32007-10-24 01:28:33 +0000112- optimize the performance of builtin.sum().
113
Neal Norwitz44f326e2007-10-05 05:29:17 +0000114- Fix warnings found by the new version of the Coverity checker.
115
Raymond Hettinger8f669372007-10-03 21:18:11 +0000116- The enumerate() builtin function is no longer bounded to sequences smaller
117 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
118 shifts from ints to longs.
119
Brett Cannon0b14f242007-09-30 19:45:10 +0000120- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
121 having a self-referential tuple, which is possible from C code. Nor did
122 object's tp_str consider that a type's tp_str could do something that could
123 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
124 respectively, fixed the issues.
125
Brett Cannon01531592007-09-17 03:28:34 +0000126- Issue #1164: It was possible to trigger deadlock when using the 'print'
127 statement to write to a file since the GIL was not released as needed. Now
128 PyObject_Print() does the right thing along with various tp_print
129 implementations of the built-in types and those in the collections module.
130
Brett Cannon4c20bc42007-09-11 21:02:28 +0000131- Issue #1147: Exceptions were directly allowing string exceptions in their
132 throw() method even though string exceptions no longer allowed.
133
Brett Cannona0c05512007-09-10 21:38:27 +0000134- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
135 list by using the recursion counter.
136
Brett Cannon1e534b52007-09-07 04:18:30 +0000137- Issue #1202533: Fix infinite recursion calls triggered by calls to
138 PyObject_Call() never calling back out to Python code to trigger recursion
139 depth updates/checks. Required the creation of a static RuntimeError
140 instance in case normalizing an exception put the recursion check value past
141 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
142
Martin v. Löwisa5136192007-09-04 14:19:28 +0000143- Patch #1031213: Decode source line in SyntaxErrors back to its original source
144 encoding.
145

149 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
150 PyVarObject_HEAD_INIT.
151
Georg Brandl7c3b50d2007-07-12 08:38:00 +0000152- Patch #1673759: add a missing overflow check when formatting floats
153 with %G.
154
Martin v. Löwis6371cd82007-06-09 07:42:52 +0000155- Patch #1733960: Allow T_LONGLONG to accept ints.
156
Walter Dörwald84a3efe2007-06-13 16:57:12 +0000157- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
158
Neal Norwitzdb2b1b32007-06-11 07:36:24 +0000159- Prevent expandtabs() on string and unicode objects from causing a segfault
160 when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +0000161
Martin v. Löwisda587ab2007-06-08 17:29:20 +0000162- Bug #1733488: Fix compilation of bufferobject.c on AIX.
163
Georg Brandl25497a12007-06-01 19:20:27 +0000164- Bug #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +0000165
Neal Norwitz0ac60192007-05-27 04:08:54 +0000166- Add new attribute names for function objects. All the func_* become
167 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
168
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +0000169- Add -3 option to the interpreter to warn about features that are
170 deprecated and will be changed/removed in Python 3.0.
171
Georg Brandl2134e752007-05-21 20:34:16 +0000172- Patch #1686487: you can now pass any mapping after '**' in function
173 calls.
174
Collin Winter62903052007-05-18 23:11:24 +0000175- except clauses may now be spelled either "except E, target:" or
176 "except E as target:". This is to provide forwards compatibility with
177 Python 3.0.
178
Brett Cannon229cee22007-05-05 01:34:02 +0000179- Deprecate BaseException.message as per PEP 352.
180
Armin Rigo9790a272007-05-02 19:23:31 +0000181- Bug #1303614: don't expose object's __dict__ when the dict is
182 inherited from a builtin base.
183
Vinay Sajip8549ce32007-05-06 17:53:37 +0000184- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +0000185 setting a plain string, ie don't expand to single letter identifiers.
186
Raymond Hettinger13936692007-04-11 18:40:58 +0000187- Request #1191699: Slices can now be pickled.
188
Raymond Hettinger4db5fe92007-04-12 04:10:00 +0000189- Request #1193128: str.translate() now allows a None argument for
190 translations that only remove characters without re-mapping the
191 remaining characters.
192
Georg Brandl5cb76c12007-03-21 09:00:39 +0000193- Patch #1682205: a TypeError while unpacking an iterable is no longer
194 masked by a generic one with the message "unpack non-sequence".
195
Neal Norwitzaa754b72007-03-21 06:39:48 +0000196- Remove unused file Python/fmod.c.
197
Guido van Rossum143b5642007-03-23 04:58:42 +0000198- Bug #1683368: The object.__init__() and object.__new__() methods are
199 now stricter in rejecting excess arguments. The only time when
200 either allows excess arguments is when it is not overridden and the
201 other one is. For backwards compatibility, when both are
202 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +0000203 warning later). Also, type.__init__() insists on the same signature
204 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +0000205
Georg Brandl2b869942007-03-17 16:08:45 +0000206- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
207 to complex using its __complex__() method before falling back to the
208 __float__() method. Therefore, the functions in the cmath module now
209 can operate on objects that define a __complex__() method.
210
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +0000211- Patch #1623563: allow __class__ assignment for classes with __slots__.
212 The old and the new class are still required to have the same slot names.
213
Collin Winter77c67bd2007-03-16 04:11:30 +0000214- Patch #1642547: Fix an error/crash when encountering syntax errors in
215 complex if statements.
216
Žiga Seilnacht20f43d32007-03-15 11:44:55 +0000217- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
218 is called with an object that is faking its type.
219
Žiga Seilnacht71436f02007-03-14 12:24:09 +0000220- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
221 name.
222
Georg Brandl5240d742007-03-13 20:46:32 +0000223- Patch #1444529: the builtin compile() now accepts keyword arguments.
224
Georg Brandl7b9c5552007-03-12 14:30:05 +0000225- Bug #1678647: write a newline after printing an exception in any
226 case, even when converting the value to a string failed.
227
Georg Brandl871f1bc2007-03-12 13:17:36 +0000228- The dir() function has been extended to call the __dir__() method on
229 its argument, if it exists. If not, it will work like before. This allows
230 customizing the output of dir() in the presence of a __getattr__().
231
Collin Winter276887b2007-03-12 16:11:39 +0000232- Patch #922167: Python no longer segfaults when faced with infinitely
233 self-recursive reload() calls (as reported by bug #742342).
234
Žiga Seilnacht89032082007-03-11 15:54:54 +0000235- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
236
Collin Wintere38051d2007-03-09 20:33:07 +0000237- Patch #1491866: change the complex() constructor to allow parthensized
238 forms. This means complex(repr(x)) now works instead of raising a
239 ValueError.
240
Georg Brandlaa2321b2007-03-07 00:40:28 +0000241- Patch #703779: unset __file__ in __main__ after running a file. This
242 makes the filenames the warning module prints much more sensible when
243 a PYTHONSTARTUP file is used.
244
Georg Brandl49aafc92007-03-07 00:34:46 +0000245- Variant of patch #697613: don't exit the interpreter on a SystemExit
246 exception if the -i command line option or PYTHONINSPECT environment
247 variable is given, but break into the interactive interpreter just like
248 on other exceptions or normal program exit.
249
Georg Brandl00cd8182007-03-06 18:41:12 +0000250- Patch #1638879: don't accept strings with embedded NUL bytes in long().
251
Georg Brandl098cd692007-03-06 12:17:50 +0000252- Bug #1674503: close the file opened by execfile() in an error condition.
253
Georg Brandl0fca97a2007-03-05 22:28:08 +0000254- Patch #1674228: when assigning a slice (old-style), check for the
255 sq_ass_slice instead of the sq_slice slot.
256
Neal Norwitz88516a62007-02-26 22:41:45 +0000257- When printing an unraisable error, don't print exceptions. before the name.
258 This duplicates the behavior whening normally printing exceptions.
259
Martin v. Löwisfd963262007-02-09 12:19:32 +0000260- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
261
Brett Cannon129bd522007-01-30 21:34:36 +0000262- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
263 catch a string exception raises DeprecationWarning.
264
Brett Cannonf5bee302007-01-23 23:21:22 +0000265- Bug #1377858: Fix the segfaulting of the interpreter when an object created
266 a weakref on itself during a __del__ call for new-style classes (classic
267 classes still have the bug).
268
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000269- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
270 frame's thread state.
271
Thomas Wouters6ed19652007-01-23 13:50:49 +0000272- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
273
Martin v. Löwis4885e7d2007-01-19 06:42:22 +0000274- Bug #1637022: Prefix AST symbols with _Py_.
275
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000276- Prevent seg fault on shutdown which could occur if an object
277 raised a warning.
278
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000279- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
280 to avoid relying on atexit.
281
Raymond Hettinger94547f72006-12-20 06:42:06 +0000282- Bug #1590891: random.randrange don't return correct value for big number
283
Georg Brandl283a1352006-11-19 08:48:30 +0000284- Patch #1586791: Better exception messages for some operations on strings,

Gregory P. Smith2b3ba582008-01-17 08:03:17 +00001063 RFC 3207 and forgets any knowledge obtained from the server not obtained
1064 from the TLS negotiation itself. Patch contributed by Bill Fenner.
1065
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00001066- Issue1339: The smtplib.SMTP class has been refactored a bit such

1090
Raymond Hettinger47317092008-01-17 03:02:14 +00001091- itertools.starmap() now accepts any iterable input. Previously, it required

1116 tuple, list, dict, set, and frozenset. Formerly, it would silently miscode
1117 subclasses of those types. Now, it raises a ValueError instead.
1118
Martin v. Löwis58bd49f2007-09-04 13:13:14 +00001119- Patch #1388440: Add set_completion_display_matches_hook and

1133 time so that opening a database previously created with the DB_DUP or
1134 DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
1135 Specifically: dictionary assignment to a DB object will replace all
1136 values for a given key when the database allows duplicate values.
1137 DB users should use DB.put(k, v) when they want to store duplicates; not
1138 DB[k] = v.
1139
Gregory P. Smithac11e022007-11-05 02:56:31 +00001140- Add the bsddb.db.DBEnv.lock_id_free method.

1430-----
1431
Christian Heimes000a0742008-01-03 22:16:32 +00001432- Added a new API function ``PyImport_ImportModuleNoBlock``.
1433
1434- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do absolute
1435 imports. In earlier versions they might have used relative imports under
1436 some conditions.
1437
1438- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE
1439 and Py_REFCNT.
1440
Andrew M. Kuchlingadc60ab2008-01-04 02:26:00 +00001441- Added case insensitive comparison methods ``PyOS_stricmp(char*, char*)``
Christian Heimes000a0742008-01-03 22:16:32 +00001442 and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
1443
Neal Norwitz8a267062006-08-19 04:25:29 +00001444- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx macro
1445 so it can be used as an expression.

Brett Cannon5e263512007-05-20 23:17:38 +00001464- Removed the macfs module. It had been deprecated since Python 2.5. This
1465 lead to the deprecation of macostools.touched() as it relied solely on macfs
1466 and was a no-op under OS X.

1475-----------------
1476
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001477- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001478 compared equal or unequal to a string and a UnicodeDecodeError
1479 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001480
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001481 Instead, the equal (==) and unequal (!=) comparison operators will
1482 now issue a UnicodeWarning and interpret the two objects as
1483 unequal. The UnicodeWarning can be filtered as desired using
1484 the warning framework, e.g. silenced completely, turned into an
1485 exception, logged, etc.
1486
1487 Note that compare operators other than equal and unequal will still
1488 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001489
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001490- Fix segfault when doing string formatting on subclasses of long.
1491
1492- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1493 with new-style classes.
1494
1495- Fix bug related to __len__ functions returning negative values with
1496 classic classes.
1497
1498- Patch #1538606, Fix __index__() clipping. There were some problems
1499 discovered with the API and how integers that didn't fit into Py_ssize_t
1500 were handled. This patch attempts to provide enough alternatives
1501 to effectively use __index__.
1502
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001503- Bug #1536021: __hash__ may now return long int; the final hash
1504 value is obtained by invoking hash on the long int.
1505
Thomas Hellerab1049c2006-08-08 17:37:00 +00001506- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1507
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001508- Bug #1535165: fixed a segfault in input() and raw_input() when
1509 sys.stdin is closed.
1510
Thomas Heller74d36f02006-08-04 18:17:40 +00001511- On Windows, the PyErr_Warn function is now exported from
1512 the Python dll again.
1513
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001514- Bug #1191458: tracing over for loops now produces a line event
1515 on each iteration. Fixing this problem required changing the .pyc
1516 magic number. This means that .pyc files generated before 2.5c1
1517 will be regenerated.
1518
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001519- Bug #1333982: string/number constants were inappropriately stored
1520 in the byte code and co_consts even if they were not used, ie
1521 immediately popped off the stack.
1522
Georg Brandle9462c72006-08-04 18:03:37 +00001523- Fixed a reference-counting problem in property().

1526Library
1527-------
1528
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001529- Fix a bug in the ``compiler`` package that caused invalid code to be
1530 generated for generator expressions.
1531
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001532- The distutils version has been changed to 2.5.0. The change to
1533 keep it programmatically in sync with the Python version running
1534 the code (introduced in 2.5b3) has been reverted. It will continue
1535 to be maintained manually as static string literal.
1536
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001537- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001538 and this cannot be converted to the required C type, an exception is
1539 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001540 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001541
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001542- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001543 an exception.
1544
Tim Petersc10c9d02006-09-05 02:18:09 +00001545- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001546 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001547 workarounds for clocks with low resolution, to stop the code yielding
1548 duplicate UUIDs.
1549
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001550- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1551 before raising SystemExit, allowing IDLE to honor quit() and exit().
1552
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001553- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1554
Georg Brandl7a1af772006-08-14 21:55:28 +00001555- Patch #1536071: trace.py should now find the full module name of a
1556 file correctly even on Windows.
1557
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001558- logging's atexit hook now runs even if the rest of the module has
1559 already been cleaned up.
1560
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001561- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001562
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001563- Bug #1531405, format_exception no longer raises an exception if
1564 str(exception) raised an exception.
1565
Neil Schemenauer06ded092006-08-04 16:20:30 +00001566- Fix a bug in the ``compiler`` package that caused invalid code to be
1567 generated for nested functions.

Georg Brandl3335a7a2006-08-14 21:42:55 +00001575- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1576 raises the correct exceptions.
1577
Thomas Heller1ce433e2006-08-14 16:20:04 +00001578- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1579 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1580
Thomas Heller86720042006-08-14 11:17:48 +00001581- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1582 uses the _as_parameter_ attribute when objects are passed to foreign
1583 function calls. The ctypes version number was changed to 1.0.1.
1584
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001585- Bug #1530559, struct.pack raises TypeError where it used to convert.
1586 Passing float arguments to struct.pack when integers are expected
1587 now triggers a DeprecationWarning.

1637Core and builtins
1638-----------------
1639
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001640- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001641 returned a long (see PEP 353).
1642
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001643- Bug #1515471: string.replace() accepts character buffers again.
1644
Neal Norwitz07aadb12006-07-30 06:55:48 +00001645- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1646 This provides the proper warning for struct.pack().
1647 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1648
Neal Norwitz0d62a062006-07-30 06:53:31 +00001649- Patch #1531113: Fix augmented assignment with yield expressions.
1650 Also fix a SystemError when trying to assign to yield expressions.
1651
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001652- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1653 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1654 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1655 excessive filesystem operations during imports.
1656
Tim Petersbc24eee2006-07-27 01:14:53 +00001657- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1658 operations on signed longs that are formally undefined by C.
1659 Unfortunately, at least one compiler now cares about that, so complicated
1660 the code to make that compiler happy again.
1661
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001662- Bug #1524310: Properly report errors from FindNextFile in os.listdir.

1665 path on Windows.
1666
Neal Norwitze1fdb322006-07-21 05:32:28 +00001667- Fix some potential crashes found with failmalloc.
1668
Neal Norwitze7563102006-07-17 01:00:16 +00001669- Fix warnings reported by Klocwork's static analysis tool.

1672 had more than 255 blank lines.
1673
Georg Brandl9dceedb2006-07-12 15:31:17 +00001674- Patch #1521179: Python now accepts the standard options ``--help`` and
1675 ``--version`` as well as ``/?`` on Windows.
1676
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001677- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001678 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001679 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001680
Tim Peters112aad32006-07-19 00:03:19 +00001681- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001682 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001683 new ``sys._current_frames()`` returns a dictionary with one entry,
1684 mapping the faux "thread id" 0 to the current frame.
1685
Ronald Oussoren3075e162006-07-25 20:28:55 +00001686- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001687

1690-------
1691
Facundo Batista6e22be72008-01-19 18:45:46 +00001692- Fix #1693149. Now you can pass several modules separated by
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00001693 comma to trace.py in the same --ignore-module option.
Facundo Batista6e22be72008-01-19 18:45:46 +00001694
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001695- Correction of patch #1455898: In the mbcs decoder, set final=False
1696 for stream decoder, but final=True for the decode function.
1697
Georg Brandl07fec3a2006-08-01 18:49:24 +00001698- os.urandom no longer masks unrelated exceptions like SystemExit or
1699 KeyboardInterrupt.
1700
Tim Peters4643c2f2006-08-10 22:45:34 +00001701- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001702 shutil.copytree on Windows
1703
Georg Brandle34ac7c2006-07-30 11:07:23 +00001704- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1705 refers to file descriptors, not file objects.
1706
Tim Petersc10c9d02006-09-05 02:18:09 +00001707- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001708 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001709 #1513611, and probably others.
1710
Georg Brandledd9b0d2006-07-29 09:33:26 +00001711- Bug #1441397: The compiler module now recognizes module and function
1712 docstrings correctly as it did in Python 2.4.
1713
Tim Peters6f681472006-07-27 23:44:37 +00001714- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1715 lost that tests are sorted by name before being run. This rarely
1716 matters for well-written tests, but can create baffling symptoms if
1717 side effects from one test to the next affect outcomes. ``DocTestFinder``
1718 has been changed to sort the list of tests it returns.
1719
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001720- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001721 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001722
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001723- Bug #978833: Really close underlying socket in _socketobject.close.
1724
Georg Brandl8c036cc2006-08-20 13:15:39 +00001725- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1726 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001727
Georg Brandlcf0c1722006-07-26 07:23:32 +00001728- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1729 to recursive calls and call it with the failing package name.
1730
Martin v. Löwis0b483032006-07-25 09:53:12 +00001731- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1732
Georg Brandlc13c34c2006-07-24 14:09:56 +00001733- Patch #1515343: Fix printing of deprecated string exceptions with a
1734 value in the traceback module.
1735
Greg Ward48fae7a2006-07-23 16:05:51 +00001736- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1737
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001738- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1739
Brett Cannoncaebe222006-07-18 04:41:36 +00001740- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1741 argument tuple. For arguments where zero is illegal, the value is forced to
1742 the minimum value that is correct. This is to support an undocumented but
1743 common way people used to fill in inconsequential information in the time
1744 tuple pre-2.4.
1745
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001746- Patch #1220874: Update the binhex module for Mach-O.
1747
Barry Warsawb110bad2006-07-21 14:51:07 +00001748- The email package has improved RFC 2231 support, specifically for
1749 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1750 (name*0=<blah>) parameter continuations. This may change the types of
1751 values returned from email.message.Message.get_param() and friends.
1752 Specifically in some cases where non-encoded continuations were used,
1753 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1754 will just return the string (since non-encoded continuations don't have
1755 charset and language parts).
1756
1757 Also, whereas % values were decoded in all parameter continuations, they are
1758 now only decoded in encoded parameter parts.
1759
Ronald Oussoren3075e162006-07-25 20:28:55 +00001760- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1761
1762- Bug #1517996: IDLE now longer shows the default Tk menu when a
1763 path browser, class browser or debugger is the frontmost window on MacOS X
1764
Barry Warsaw00decd72006-07-27 23:43:15 +00001765- Patch #1520294: Support for getset and member descriptors in types.py,
1766 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1767 of an object against these built-in types and more importantly, for getting
1768 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001771Extension Modules
1772-----------------
1773
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001774- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1775 a socket operation on a socket with a timeout, the exception will be
1776 caught correctly. Previously, the exception was not caught.
1777
Thomas Heller1393d6a2006-07-28 21:43:20 +00001778- Patch #1529514: The _ctypes extension is now compiled on more
1779 openbsd target platforms.
1780
Tim Peters9cab5932006-07-28 00:30:00 +00001781- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1782 a memory leak, affecting pickles and deep copies.
1783
Tim Petersbc24eee2006-07-27 01:14:53 +00001784- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001785 Paul Eggert.
1786
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001787- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1788
Thomas Hellerce049a02006-07-14 17:51:14 +00001789- Patch #1521817: Index range checking on ctypes arrays containing
1790 exactly one element enabled again. This allows iterating over these
1791 arrays, without the need to check the array size before.
1792
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001793- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001794 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001795 /dev/null in certain cases; this is now fixed.
1796
Thomas Heller47d7a062006-07-12 08:43:47 +00001797- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1798 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001799
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001800- Because of a misspelled preprocessor symbol, ctypes was always
1801 compiled without thread support; this is now fixed.
1802
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001803- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1804 methods now allow their database parameter to be None as the
1805 sleepycat API allows.
1806
Matt Flemingec926502006-07-28 11:27:27 +00001807- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1808 bluetooth API compared with Linux and FreeBSD.
1809
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001810Tests
1811-----
1812
1813- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1814 how long the test file should take to play. Now accepts taking 2.93 secs
1815 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1816
Georg Brandl4793aa32006-07-28 18:31:39 +00001817- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1818 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1819 run via ``regrtest.py``. Now they do.

1822-----
1823
1824- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1825
Ronald Oussoren26cad082006-08-01 21:00:57 +00001826Mac
1827---
1828
1829- PythonLauncher now works correctly when the path to the script contains
1830 characters that are treated specially by the shell (such as quotes).
1831
1832- Bug #1527397: PythonLauncher now launches scripts with the working directory
1833 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001834 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001835 expect.

1844-----------------
1845
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001846- Bug #1441486: The literal representation of -(sys.maxint - 1)
1847 again evaluates to a int object, not a long.
1848
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001849- Bug #1501934: The scope of global variables that are locally assigned
1850 using augmented assignment is now correctly determined.
1851
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001852- Bug #927248: Recursive method-wrapper objects can now safely
1853 be released.
1854
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001855- Bug #1417699: Reject locale-specific decimal point in float()
1856 and atof().
1857
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001858- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1859 omit a default "error" argument for NULL pointer. This allows
1860 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001861
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001862- Bug #1519018: 'as' is now validated properly in import statements.
1863
Neal Norwitz28746ab2006-07-09 22:14:42 +00001864- On 64 bit systems, int literals that use less than 64 bits are
1865 now ints rather than longs.
1866
Neal Norwitzed657552006-07-10 00:04:44 +00001867- Bug #1512814, Fix incorrect lineno's when code at module scope
1868 started after line 256.
1869
Tim Peters32a83612006-07-10 21:08:24 +00001870- New function ``sys._current_frames()`` returns a dict mapping thread
1871 id to topmost thread stack frame. This is for expert use, and is
1872 especially useful for debugging application deadlocks. The functionality
1873 was previously available in Fazal Majid's ``threadframe`` extension
1874 module, but it wasn't possible to do this in a wholly threadsafe way from
1875 an extension.

1892
Thomas Woutersadd19112006-07-05 11:03:49 +00001893- string.Template() now correctly handles tuple-values. Previously,
1894 multi-value tuples would raise an exception and single-value tuples would
1895 be treated as the value they contain, instead.
1896
Martin v. Löwisede77f52006-07-03 13:01:35 +00001897- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1899
Martin v. Löwis45482392006-07-03 12:28:58 +00001900- Bug #1267547: Put proper recursive setup.py call into the

1902
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001903- Bug #1514693: Update turtle's heading when switching between
1904 degrees and radians.
1905
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001906- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001907 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001908
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001909- Bug #1514703: Only setup canvas window in turtle when the canvas
1910 is created.
1911
Martin v. Löwis7596e832006-07-01 15:33:37 +00001912- Bug #1513223: .close() of a _socketobj now releases the underlying
1913 socket again, which then gets closed as it becomes unreferenced.
1914
Fred Drake10497c82006-06-29 02:57:48 +00001915- Bug #1504333: Make sgmllib support angle brackets in quoted
1916 attribute values.
1917
1918- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1919 sgmllib ('[' and ']' were not accepted).
1920
Georg Brandl1be63af2006-06-28 20:23:25 +00001921- Fix a bug in the turtle module's end_fill function.
1922
Brett Cannon53ab5b72006-06-22 16:49:14 +00001923- Bug #1510580: The 'warnings' module improperly required that a Warning
1924 category be either a types.ClassType and a subclass of Warning. The proper
1925 check is just that it is a subclass with Warning as the documentation states.
1926
Georg Brandlad29e632006-06-21 17:45:17 +00001927- The compiler module now correctly compiles the new try-except-finally
1928 statement (bug #1509132).
1929
Neal Norwitz60373cd2006-06-22 06:30:50 +00001930- The wsgiref package is now installed properly on Unix.
1931
Vinay Sajip28e57612006-07-01 10:45:20 +00001932- A bug was fixed in logging.config.fileConfig() which caused a crash on
1933 shutdown when fileConfig() was called multiple times.
1934
Gerhard Häring762fbd32006-07-02 17:48:30 +00001935- The sqlite3 module did cut off data from the SQLite database at the first
1936 null character before sending it to a custom converter. This has been fixed
1937 now.
1938
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001939Extension Modules
1940-----------------
1941
Tim Peters112aad32006-07-19 00:03:19 +00001942- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1943 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1944 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001945
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001946- Assigning None to pointer type fields in ctypes structures possible
1947 overwrote the wrong fields, this is fixed now.
1948
1949- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1950 on non-Windows platforms.
1951
1952- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1953 integer or long, without range checking.
1954
1955- Patch #1517790: It is now possible to use custom objects in the ctypes
1956 foreign function argtypes sequence as long as they provide a from_param
1957 method, no longer is it required that the object is a ctypes type.
1958
1959- The '_ctypes' extension module now works when Python is configured
1960 with the --without-threads option.
1961
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001962- Bug #1513646: os.access on Windows now correctly determines write

1977
Tim Peters32a83612006-07-10 21:08:24 +00001978- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001979 Previously, the slight difference could cause compilation errors of the
1980 'zlib' module on systems with more than one version of zlib.
1981
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001982- The MSI compileall step was fixed to also support a TARGETDIR
1983 with spaces in it.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002012
2013Core and builtins
2014-----------------
2015
Georg Brandla56b9152006-06-19 06:35:54 +00002016- Patch #1507676: Error messages returned by invalid abstract object operations
2017 (such as iterating over an integer) have been improved and now include the
2018 type of the offending object to help with debugging.
2019
Brett Cannonea3912b2006-06-13 21:46:41 +00002020- Bug #992017: A classic class that defined a __coerce__() method that returned
2021 its arguments swapped would infinitely recurse and segfault the interpreter.
2022
Neal Norwitz909eb122006-06-12 02:13:21 +00002023- Fix the socket tests so they can be run concurrently.
2024
Neal Norwitzb9845e72006-06-12 02:11:18 +00002025- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00002026 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00002027
Brett Cannon22565aa2006-06-09 22:31:23 +00002028- Bug #532646: object.__call__() will continue looking for the __call__
2029 attribute on objects until one without one is found. This leads to recursion
2030 when you take a class and set its __call__ attribute to an instance of the
2031 class. Originally fixed for classic classes, but this fix is for new-style.
2032 Removes the infinite_rec_3 crasher.
2033
Georg Brandl24250812006-06-09 18:45:48 +00002034- The string and unicode methods startswith() and endswith() now accept
2035 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
2036
Brett Cannonde3b0522006-06-08 17:00:45 +00002037- Buffer objects, at the C level, never used the char buffer
2038 implementation even when the char buffer for the wrapped object was
2039 explicitly requested (originally returned the read or write buffer).
2040 Now a TypeError is raised if the char buffer is not present but is
2041 requested.
2042
Georg Brandlddbaa662006-06-04 21:56:52 +00002043- Patch #1346214: Statements like "if 0: suite" are now again optimized
2044 away like they were in Python 2.4.
2045
Georg Brandlb7c8f542006-05-27 12:30:25 +00002046- Builtin exceptions are now full-blown new-style classes instead of
2047 instances pretending to be classes, which speeds up exception handling
2048 by about 80% in comparison to 2.5a2.
2049
Martin v. Löwisd004fc82006-05-27 08:36:52 +00002050- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
2051 Unicode 4.1.
2052
Georg Brandlf4ef1162006-05-26 18:03:31 +00002053- Patch #921466: sys.path_importer_cache is now used to cache valid and
2054 invalid file paths for the built-in import machinery which leads to
2055 fewer open calls on startup.
2056
Tim Peters696cf432006-05-24 21:10:40 +00002057- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
2058 of-2 bases. The largest speedup is for inputs with about 1000 decimal
2059 digits. Conversion from non-power-of-2 bases remains quadratic-time in
2060 the number of input digits (it was and remains linear-time for bases
2061 2, 4, 8, 16 and 32).
2062
Tim Petersb713ec22006-05-23 18:45:30 +00002063- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
2064 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
2065 an integer close to ``sys.maxint``. This was repaired by patch
2066 #1335972, which also gives a nice speedup.
2067
Richard Jonescebbefc2006-05-23 18:28:17 +00002068- Patch #1337051: reduced size of frame objects.
2069
2070- PyErr_NewException now accepts a tuple of base classes as its
2071 "base" parameter.
2072
Richard Jones7c88dcc2006-05-23 10:37:38 +00002073- Patch #876206: function call speedup by retaining allocated frame
2074 objects.
2075
Georg Brandl7b90e162006-05-18 07:01:27 +00002076- Bug #1462152: file() now checks more thoroughly for invalid mode
2077 strings and removes a possible "U" before passing the mode to the
2078 C library function.
2079
Neal Norwitz1004a532006-05-15 07:17:23 +00002080- Patch #1488312, Fix memory alignment problem on SPARC in unicode
2081
Neal Norwitz373f0a72006-05-15 07:04:36 +00002082- Bug #1487966: Fix SystemError with conditional expression in assignment
2083
Martin v. Löwis879768d2006-05-11 13:28:43 +00002084- WindowsError now has two error code attributes: errno, which carries
2085 the error values from errno.h, and winerror, which carries the error
2086 values from winerror.h. Previous versions put the winerror.h values
2087 (from GetLastError()) into the errno attribute.
2088
Martin v. Löwis77736712006-05-04 05:51:03 +00002089- Patch #1475845: Raise IndentationError for unexpected indent.
2090
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00002091- Patch #1479181: split open() and file() from being aliases for each other.
2092
Tim Peters44bd9862006-06-01 13:49:23 +00002093- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
2094 methods were always silently ignored by dictionaries when comparing keys.
2095 They are now passed through (except when using the C API function
2096 ``PyDict_GetItem()``, whose semantics did not change).
2097
2098- Bug #1456209: In some obscure cases it was possible for a class with a
2099 custom ``__eq__()`` method to confuse dict internals when class instances
2100 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
2101 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002103Extension Modules
2104-----------------
2105
Trent Mick960a3f82006-06-28 20:30:41 +00002106- Bug #1295808: expat symbols should be namespaced in pyexpat
2107
2108- Patch #1462338: Upgrade pyexpat to expat 2.0.0
2109
Brett Cannon6ee7d012006-06-08 16:23:04 +00002110- Change binascii.hexlify to accept a read-only buffer instead of only a char
2111 buffer and actually follow its documentation.
2112
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00002113- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
2114
Nick Coghlanc649ec52006-05-29 12:43:05 +00002115- Patch #1478788 (modified version): The functional extension module has
2116 been renamed to _functools and a functools Python wrapper module added.
2117 This provides a home for additional function related utilities that are
2118 not specifically about functional programming. See PEP 309.
2119
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00002120- Patch #1493701: performance enhancements for struct module.
2121
Georg Brandl378d5922006-05-17 14:26:50 +00002122- Patch #1490224: time.altzone is now set correctly on Cygwin.
2123
Georg Brandl8d3342b2006-05-16 07:38:27 +00002124- Patch #1435422: zlib's compress and decompress objects now have a
2125 copy() method.
2126
Andrew MacIntyre92913322006-06-13 15:04:24 +00002127- Patch #1454481: thread stack size is now tunable at runtime for thread
2128 enabled builds on Windows and systems with Posix threads support.
2129
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002130- On Win32, os.listdir now supports arbitrarily-long Unicode path names
2131 (up to the system limit of 32K characters).
2132
2133- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
2134 As a result, these functions now raise WindowsError instead of OSError.
2135
Tim Peters7a822da2006-05-25 21:50:17 +00002136- ``time.clock()`` on Win64 should use the high-performance Windows
2137 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
2138 Windows platforms).
2139
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002140- Calling Tk_Init twice is refused if the first call failed as that
2141 may deadlock.
2142
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00002143- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
2144 accept it without potentially using an uninitialized pointer.
2145
2146- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
2147 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
2148 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00002149
Gregory P. Smith372b5832006-06-05 18:48:21 +00002150- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00002151 [pybsddb project SF patch number 1466734]
2152
Gregory P. Smith372b5832006-06-05 18:48:21 +00002153- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
2154 parameter is supplied. [SF pybsddb bug #1477863]
2155
Gregory P. Smith3c228b12006-06-05 23:59:37 +00002156- bsddb: the __len__ method of a DB object has been fixed to return correct
2157 results. It could previously incorrectly return 0 in some cases.
2158 Fixes SF bug 1493322 (pybsddb bug 1184012).
2159
Gregory P. Smithff7d9912006-06-08 05:17:08 +00002160- bsddb: the bsddb.dbtables Modify method now raises the proper error and
2161 aborts the db transaction safely when a modifier callback fails.
2162 Fixes SF python patch/bug #1408584.
2163
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002164- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00002165 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002166 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
2167 database calls that would previously deadlock. [SF python bug #775414]
2168
Vinay Sajip28e57612006-07-01 10:45:20 +00002169- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00002170
Walter Dörwald4994d952006-06-19 08:07:50 +00002171- Patch #1506645: add Python wrappers for the curses functions
2172 is_term_resized, resize_term and resizeterm.

2175-------
2176
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00002177- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
2178 functions.
2179
Martin v. Löwis3798da02006-06-17 18:44:27 +00002180- Patch #812986: Update turtle output even if not tracing.
2181
Vinay Sajip28e57612006-07-01 10:45:20 +00002182- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00002183 Tkinter.BaseWidget.
2184
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00002185- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
2186
Martin v. Löwis337487e2006-06-17 09:15:14 +00002187- Patch #763580: Add name and value arguments to Tkinter variable
2188 classes.
2189
Georg Brandl83cc0d02006-06-14 08:50:03 +00002190- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
2191 mime.types file for determining MIME types.
2192
Georg Brandl2605ca82006-06-14 06:08:31 +00002193- Bug #1339007: Shelf objects now don't raise an exception in their
2194 __del__ method when initialization failed.
2195
Martin v. Löwisd8251432006-06-14 05:21:04 +00002196- Patch #1455898: The MBCS codec now supports the incremental mode for
2197 double-byte encodings.
2198
Tim Peters43898b42006-06-14 04:09:25 +00002199- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2200 guarantee that adjacent triples in the return list always describe
2201 non-adjacent blocks. Previously, a pair of matching blocks could end
2202 up being described by multiple adjacent triples that formed a partition
2203 of the matching pair.
2204
Greg Ward0e0c9f42006-06-11 16:24:11 +00002205- Bug #1498146: fix optparse to handle Unicode strings in option help,
2206 description, and epilog.
2207
Greg Wardd1c797e2006-06-11 14:42:41 +00002208- Bug #1366250: minor optparse documentation error.
2209
Greg Ward7f547402006-06-11 00:40:49 +00002210- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
2211 clarify docs.
2212
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002213- The wsgiref package has been added to the standard library.
2214
Nick Coghlan676725d2006-06-08 13:54:49 +00002215- The functions update_wrapper() and wraps() have been added to the functools
2216 module. These make it easier to copy relevant metadata from the original
2217 function when writing wrapper functions.
2218
Tim Petersd6a9eef2006-06-05 01:48:21 +00002219- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2220 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002221
Martin v. Löwis3f767792006-06-04 19:36:28 +00002222- Patch #1359618: Speed up charmap encoder by using a trie structure
2223 for lookup.
2224
Tim Petersd609b1a2006-06-02 23:22:51 +00002225- The functions in the ``pprint`` module now sort dictionaries by key
2226 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2227 if and only if its display required more than one line, although that
2228 wasn't documented. The new behavior increases predictability; e.g.,
2229 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2230
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002231- Patch #1497027: try HTTP digest auth before basic auth in urllib2
2232 (thanks for J. J. Lee).
2233
Georg Brandl2b330372006-05-28 20:23:12 +00002234- Patch #1496206: improve urllib2 handling of passwords with respect to
2235 default HTTP and HTTPS ports.
2236
George Yoshidaf3c65de2006-05-28 16:39:09 +00002237- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
2238
Bob Ippolito7298f272006-05-23 18:43:47 +00002239- Patch #1281707: speed up gzip.readline.
2240
Georg Brandlb89316f2006-05-17 15:51:16 +00002241- Patch #1180296: Two new functions were added to the locale module:
2242 format_string() to get the effect of "format % items" but locale-aware,
2243 and currency() to format a monetary number with currency sign.
2244
Georg Brandle3a25832006-05-17 14:56:04 +00002245- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2246 and several features added, such as speed and geometry control.
2247
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002248- Patch #1488881: add support for external file objects in bz2 compressed
2249 tarfiles.
2250
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002251- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2252 stdout arguments, making it possible to redirect input and output
2253 for remote debugging.
2254
2255- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2256 a couple of issues, notably handling of long file names using the
2257 GNU LONGNAME extension.
2258
2259- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2260 new flag when ``name`` is already the name of an option flag.
2261
2262- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2263 package.
2264
2265- Patch #1472854: make the rlcompleter.Completer class usable on non-
2266 UNIX platforms.
2267
2268- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
2269
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00002270- Bug #1472827: correctly escape newlines and tabs in attribute values in
2271 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002301What's New in Python 2.5 alpha 2?
2302=================================
2303
2304*Release date: 27-APR-2006*
2305
2306Core and builtins
2307-----------------
2308
Thomas Heller1b046642006-04-18 18:51:06 +00002309- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2310 by converting these apis from macros into exported functions again:
2311
2312 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2313 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2314 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2315 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2316 PyRun_String Py_CompileString
2317
Martin v. Löwis45294a92006-04-18 06:24:08 +00002318- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2319
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002320- All uses of PyStructSequence_InitType have been changed to initialize
2321 the type objects only once, even if the interpreter is initialized
2322 multiple times.
2323
Neal Norwitz61546162006-04-14 05:20:28 +00002324- Bug #1454485, array.array('u') could crash the interpreter. This was
2325 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2326 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2327
2328- Py_UNICODE is unsigned. It was always documented as unsigned, but
2329 due to a bug had a signed value in previous versions.
2330
Tim Peters3a5e8b12006-04-11 01:44:07 +00002331- Patch #837242: ``id()`` of any Python object always gives a positive
2332 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2333 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002334 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002335 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002336
Tim Peters3a5e8b12006-04-11 01:44:07 +00002337 def __hash__(self):
2338 return id(self) # WRONG
2339
2340 because a hash result must be a (short) Python int but it was always
2341 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002342 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002343 was always usable as a hash value before this patch. That's no longer
2344 necessarily so.
2345
2346- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002347 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002348 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002349 #1454844)
2350
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002351- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2352 involving generators that have paused outside of any ``try`` or ``with``
2353 blocks. (In 2.5a1, a paused generator that was part of a reference
2354 cycle could not be garbage collected, regardless of whether it was
2355 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00002356
Anthony Baxter51bcb682006-04-05 14:51:42 +00002357Extension Modules
2358-----------------
2359
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00002360- Patch #1191065: Fix preprocessor problems on systems where recvfrom
2361 is a macro.
2362
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002363- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2364 fails with an error condition.
2365
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002366- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2367
2368- Bug #1117761: bsddb.*open() no longer raises an exception when using
2369 the cachesize parameter.
2370
2371- Bug #1149413: bsddb.*open() no longer raises an exception when using
2372 a temporary db (file=None) with the 'n' flag to truncate on open.
2373
2374- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2375 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002376
Armin Rigoa9017c32006-04-19 11:50:27 +00002377- Patch #1062014: AF_UNIX sockets under Linux have a special
2378 abstract namespace that is now fully supported.
2379
Anthony Baxter51bcb682006-04-05 14:51:42 +00002380Library
2381-------
2382
Peter Astrand7d1d4362006-07-14 14:04:45 +00002383- Bug #1223937: subprocess.CalledProcessError reports the exit status
2384 of the process using the returncode attribute, instead of
2385 abusing errno.
2386
Tim Peters711bf302006-04-25 03:31:36 +00002387- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2388 a doctest to be skipped (the code is not run, and the expected output
2389 or exception is ignored).
2390
Nick Coghlanda2268f2006-04-24 04:37:15 +00002391- Fixed contextlib.nested to cope with exceptions being raised and
2392 caught inside exit handlers.
2393
Greg Wardab05edc2006-04-23 03:47:58 +00002394- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2395 hex, octal, or binary; add ``append_const`` action; keep going if
2396 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2397 added ``epilog`` for better help generation).
2398
Tim Peters21fbd572006-04-21 21:18:10 +00002399- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2400 called from a thread spawned as a side effect of importing a module.
2401
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002402- The pydoc module now supports documenting packages contained in
2403 .zip or .egg files.
2404
2405- The pkgutil module now has several new utility functions, such
2406 as ``walk_packages()`` to support working with packages that are either
2407 in the filesystem or zip files.
2408
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002409- The mailbox module can now modify and delete messages from
2410 mailboxes, in addition to simply reading them. Thanks to Gregory
2411 K. Johnson for writing the code, and to the 2005 Google Summer of
2412 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002413
Tim Petersc7605f22006-04-17 21:12:33 +00002414- The ``__del__`` method of class ``local`` in module ``_threading_local``
2415 returned before accomplishing any of its intended cleanup.
2416
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002417- Patch #790710: Add breakpoint command lists in pdb.
2418
Martin v. Löwis0db2a982006-04-16 20:55:38 +00002419- Patch #1063914: Add Tkinter.Misc.clipboard_get().
2420
Martin v. Löwis4b501e62006-04-15 08:41:11 +00002421- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
2422
Anthony Baxtere29002c2006-04-12 12:07:31 +00002423- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2424 Windows. Bug #1469163.
2425
Phillip J. Eby47032112006-04-11 01:07:43 +00002426- The warnings, linecache, inspect, traceback, site, and doctest modules
2427 were updated to work correctly with modules imported from zipfiles or
2428 via other PEP 302 __loader__ objects.
2429
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002430- Patch #1467770: Reduce usage of subprocess._active to processes which
2431 the application hasn't waited on.
2432
Martin v. Löwisb04dee92006-04-10 08:34:21 +00002433- Patch #1462222: Fix Tix.Grid.
2434
Neal Norwitza31bf182006-04-09 03:35:43 +00002435- Fix exception when doing glob.glob('anything*/')
2436
Skip Montanaro262fb922006-04-21 02:31:07 +00002437- The pstats.Stats class accepts an optional stream keyword argument to
2438 direct output to an alternate file-like object.
2439
Anthony Baxter51bcb682006-04-05 14:51:42 +00002440Build
2441-----
2442
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002443- The Makefile now has a reindent target, which runs reindent.py on
2444 the library.
2445
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002446- Patch #1470875: Building Python with MS Free Compiler
2447
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002448- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002449
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002450- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2451 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002452 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002453 CXX from --with-cxx-main, see description in README.
2454
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002455- Patch #1429775: Link extension modules with the shared libpython.
2456
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002457- Fixed a libffi build problem on MIPS systems.
2458
Tim Peters8931ff12006-05-13 23:28:20 +00002459- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2460 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2461 and "%zu" for unsigned integers of type ``size_t``.
2462
Anthony Baxter51bcb682006-04-05 14:51:42 +00002463Tests
2464-----
2465
Nick Coghlanda2268f2006-04-24 04:37:15 +00002466- test_contextlib now checks contextlib.nested can cope with exceptions
2467 being raised and caught inside exit handlers.
2468
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002469- test_cmd_line now checks operation of the -m and -c command switches
2470
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002471- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2472 it separately and by hand. It also wasn't cleaning up its changes to
2473 the current Decimal context.
2474
Thomas Woutersabd08882006-04-26 15:53:30 +00002475- regrtest.py now has a -M option to run tests that test the new limits of
2476 containers, on 64-bit architectures. Running these tests is only sensible
2477 on 64-bit machines with more than two gigabytes of memory. The argument
2478 passed is the maximum amount of memory for the tests to use.
2479
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00002480Tools
2481-----
2482
2483- Added the Python benchmark suite pybench to the Tools/ directory;
2484 contributed by Marc-Andre Lemburg.
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002485
Anthony Baxter51bcb682006-04-05 14:51:42 +00002486Documentation
2487-------------
2488
Tim Petersb06d28c2006-05-12 01:57:59 +00002489- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2490
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002491- PEP 343: Added Context Types section to the library reference
2492 and attempted to bring other PEP 343 related documentation into
2493 line with the implementation and/or python-dev discussions.
2494
Tim Peters8dc73d22006-04-24 02:03:16 +00002495- Bug #1337990: clarified that ``doctest`` does not support examples
2496 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +00002497
2498
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002499What's New in Python 2.5 alpha 1?
2500=================================
2501
Anthony Baxterebed3f62006-04-03 15:03:44 +00002502*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002503
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002504Core and builtins
2505-----------------
2506
Nick Coghlan43832302006-04-23 17:04:07 +00002507- PEP 338: -m command line switch now delegates to runpy.run_module
2508 allowing it to support modules in packages and zipfiles
2509
Martin v. Löwisc661b882006-04-20 04:54:23 +00002510- On Windows, .DLL is not an accepted file name extension for
2511 extension modules anymore; extensions are only found if they
2512 end in .PYD.
2513
Martin v. Löwisea62d252006-04-03 10:56:49 +00002514- Bug #1421664: sys.stderr.encoding is now set to the same value as
2515 sys.stdout.encoding.
2516
Neal Norwitz92e212f2006-04-03 04:48:37 +00002517- __import__ accepts keyword arguments.
2518
Georg Brandlccadf842006-03-31 18:54:53 +00002519- Patch #1460496: round() now accepts keyword arguments.
2520
Anthony Baxter262c00a2006-03-30 10:53:17 +00002521- Fixed bug #1459029 - unicode reprs were double-escaped.
2522
Hye-Shik Changd478f342006-03-23 12:32:36 +00002523- Patch #1396919: The system scope threads are reenabled on FreeBSD
2524 5.4 and later versions.
2525
Neal Norwitze98ccf62006-03-23 05:39:47 +00002526- Bug #1115379: Compiling a Unicode string with an encoding declaration
2527 now gives a SyntaxError.
2528
Georg Brandlabd1ff82006-03-18 07:59:59 +00002529- Previously, Python code had no easy way to access the contents of a
2530 cell object. Now, a ``cell_contents`` attribute has been added
2531 (closes patch #1170323).
2532
Tim Peterscf79aac2006-03-16 01:14:46 +00002533- Patch #1123430: Python's small-object allocator now returns an arena to
2534 the system ``free()`` when all memory within an arena becomes unused
2535 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2536 freed. Some applications will see a drop in virtual memory size now,
2537 especially long-running applications that, from time to time, temporarily
2538 use a large number of small objects. Note that when Python returns an
2539 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002540 platform C library will in turn return that memory to the operating system.
2541 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002542 appears to be effective at least on Microsoft C and gcc-based systems.
2543 Thanks to Evan Jones for hard work and patience.
2544
Georg Brandl533ff6f2006-03-08 18:09:27 +00002545- Patch #1434038: property() now uses the getter's docstring if there is
2546 no "doc" argument given. This makes it possible to legitimately use
2547 property() as a decorator to produce a read-only property.
2548
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002549- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2550 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2551 of requiring an int or long in slicing and a few other contexts, enabling
2552 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2553
Neal Norwitz995acdf2006-03-07 05:01:00 +00002554- Fixed various bugs reported by Coverity's Prevent tool.
2555
Brett Cannonbf364092006-03-01 04:25:17 +00002556- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2557 new exception base class, BaseException, which has a new message attribute.
2558 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2559 Raising a string exception now raises a DeprecationWarning.
2560
Thomas Woutersfb609f42006-02-28 16:37:25 +00002561- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2562 explicitly relative, using 'from .module import name' to mean 'from the same
2563 package as this module is in. Imports without dots still default to the
2564 old relative-then-absolute, unless 'from __future__ import
2565 absolute_import' is used.
2566
Brett Cannona7446e32006-02-27 23:39:10 +00002567- Properly check if 'warnings' raises an exception (usually when a filter set
2568 to "error" is triggered) when raising a warning for raising string
2569 exceptions.
2570
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002571- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002572 The name was removed from Include/code.h.
2573
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002574- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002575
Guido van Rossum1968ad32006-02-25 22:38:04 +00002576- Patch 1433928:
2577 - The copy module now "copies" function objects (as atomic objects).
2578 - dict.__getitem__ now looks for a __missing__ hook before raising
2579 KeyError.
2580
Tim Peters84ef21c2006-02-28 20:39:06 +00002581- PEP 343: with statement implemented. Needs ``from __future__ import
2582 with_statement``. Use of 'with' as a variable will generate a warning.
2583 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002584 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002585 The following objects have __context__ methods:
2586 - The built-in file type.
2587 - The thread.LockType type.
2588 - The following types defined by the threading module:
2589 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2590 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002591
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002592- Fix the encodings package codec search function to only search
2593 inside its own package. Fixes problem reported in patch #1433198.
2594
2595 Note: Codec packages should implement and register their own
2596 codec search function. PEP 100 has the details.
2597
Tim Peters9ea89d22006-06-04 03:26:02 +00002598- PEP 353: Using ``Py_ssize_t`` as the index type.
2599
2600- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2601 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2602 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2603 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2604 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002605
Neal Norwitzfc76d632006-01-10 06:03:13 +00002606- Patch #1400181, fix unicode string formatting to not use the locale.
2607 This is how string objects work. u'%f' could use , instead of .
2608 for the decimal point. Now both strings and unicode always use periods.
2609
Neal Norwitz671b9e32006-01-09 07:07:12 +00002610- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2611 configure would break checking curses.h.
2612
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002613- Bug #959576: The pwd module is now builtin. This allows Python to be
2614 built on UNIX platforms without $HOME set.
2615
Neal Norwitzc10978f2005-12-19 06:07:16 +00002616- Bug #1072182, fix some potential problems if characters are signed.
2617
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002618- Bug #889500, fix line number on SyntaxWarning for global declarations.
2619
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002620- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2621
Neal Norwitze7214a12005-12-18 05:03:17 +00002622- Support for converting hex strings to floats no longer works.
2623 This was not portable. float('0x3') now raises a ValueError.
2624
Barry Warsaw2a38a862005-12-18 01:27:35 +00002625- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002626 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002627 is now displayed in interactive prompt banner.
2628
Georg Brandlfa166682005-12-17 21:45:17 +00002629- Implementation of PEP 341 - Unification of try/except and try/finally.
2630 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002631 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002632
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002633- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2634 now encodes backslash correctly.
2635
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002636- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2637
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002638- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002639 and long longs.
2640
Neal Norwitz67715f02005-11-09 06:59:35 +00002641- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002642 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002643 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002644
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002645- Replaced most Unicode charmap codecs with new ones using the
2646 new Unicode translate string feature in the builtin charmap
2647 codec; the codecs were created from the mapping tables available
2648 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2649 encodings now include a mapping for the Apple logo)
2650
Tim Peterse3547fd2005-12-16 23:13:57 +00002651- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002652
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002653- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002654
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002655- A new AST parser implementation was completed. The abstract
2656 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002657 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002658
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002659- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002660 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2661
Neal Norwitz708e51a2005-10-03 04:48:15 +00002662- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2663
Neal Norwitz11bd1192005-10-03 00:54:56 +00002664- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2665 Provide a warning when a directory is passed on the command line.
2666
Neal Norwitz40d37812005-10-02 01:48:49 +00002667- Fix segfault with invalid coding.
2668
2669- SF bug #772896: unknown encoding results in MemoryError.
2670
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002671- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002672 supported a __len__() method which evaluated to False when the iterator
2673 was empty.
2674
Guido van Rossum630db602005-09-20 18:49:54 +00002675- On 64-bit platforms, when __len__() returns a value that cannot be
2676 represented as a C int, raise OverflowError.
2677
Skip Montanarof8948ca2005-09-19 03:54:46 +00002678- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002679 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002680
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002681- SF bug #893549: parsing keyword arguments was broken with a few format
2682 codes.
2683
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002684- Changes donated by Elemental Security to make it work on AIX 5.3
2685 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2686 bug #105470: test_pwd fails on 64bit system (Opteron).
2687
Guido van Rossum539c6622005-09-14 17:49:54 +00002688- Changes donated by Elemental Security to make it work on HP-UX 11 on
2689 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2690
Georg Brandl4550b8d2005-08-26 06:43:52 +00002691- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002692 (fixes bug #1119418).
2693
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002694- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2695
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002696- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2697 exceptions that cause a function to exit.
2698
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002699- The implementation of set() and frozenset() was revised to use its
2700 own internal data structure. Memory consumption is reduced by 1/3
2701 and there are modest speed-ups as well. The API is unchanged.
2702
Tim Petersde7990b2005-07-17 23:45:23 +00002703- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2704
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002705- SF bug #1229429: PyObject_CallMethod failed to decrement some
2706 reference counts in some error exit cases.
2707
Tim Petersecc6e6a2005-07-10 22:30:55 +00002708- SF bug #1185883: Python's small-object memory allocator took over
2709 a block managed by the platform C library whenever a realloc specified
2710 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002711 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002712 portable way to copy data from the C-managed block into Python's
2713 small-object space without risking a memory fault. Python's small-object
2714 realloc now leaves such blocks under the control of the platform C
2715 realloc.
2716
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002717- SF bug #1232517: An overflow error was not detected properly when
2718 attempting to convert a large float to an int in os.utime().
2719
Raymond Hettinger3296e692005-06-29 23:29:56 +00002720- SF bug #1224347: hex longs now print with lowercase letters just
2721 like their int counterparts.
2722
Michael W. Hudson188d4362005-06-20 16:52:57 +00002723- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2724 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2725 interpreter states; back out that fix and do a better job (see
2726 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2727 for a longer write-up of the problem).
2728
Michael W. Hudsondf888462005-06-03 14:41:55 +00002729- SF patch #1180995: marshal now uses a binary format by default when
2730 serializing floats.
2731
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002732- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2733 the routines that promise to produce IEEE 754 binary representations
2734 of floats now simply copy bytes around.
2735
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002736- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2737 278.
2738
Brett Cannonc3647ac2005-04-26 03:45:26 +00002739- patch #1109424: int, long, float, complex, and unicode now check for the
2740 proper magic slot for type conversions when subclassed. Previously the
2741 magic slot was ignored during conversion. Semantics now match the way
2742 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002743 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002744 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002745 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002746
Barry Warsawc8d907c2005-04-19 23:43:40 +00002747- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2748 NULL, now raise an AttributeError when attempting to set or delete the
2749 attribute. Previously a TypeError was raised, but this was inconsistent
2750 with the equivalent pure-Python implementation.
2751
Michael W. Hudson774479c2005-04-18 08:46:17 +00002752- It is now safe to call PyGILState_Release() before
2753 PyEval_InitThreads() (note that if there is reason to believe there
2754 are multiple threads around you still must call PyEval_InitThreads()
2755 before using the Python API; this fix is for extension modules that
2756 have no way of knowing if Python is multi-threaded yet).
2757
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002758- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2759 disabled caused a crash.
2760
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002761- Bug #1165306: instancemethod_new allowed the creation of a method
2762 with im_class == im_self == NULL, which caused a crash when called.
2763
Tim Petersecc6e6a2005-07-10 22:30:55 +00002764- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002765 fixes the crash seen in bug #1165761
2766
Raymond Hettinger96229b12005-03-11 06:49:40 +00002767- Added two new builtins, any() and all().
2768
Brett Cannon409d8f22005-03-05 06:47:57 +00002769- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002770 (e.g., ``class C(): pass`` is no longer a syntax error).
2771 Patch #1176012 added support to the 'parser' module and 'compiler' package
2772 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002773
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002774- Patch #1115086: Support PY_LONGLONG in structmember.
2775
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002776- Bug #1155938: new style classes did not check that __init__() was
2777 returning None.
2778
Tim Petersecc6e6a2005-07-10 22:30:55 +00002779- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002780 ('\') with a specific error message.
2781
Martin v. Löwisff232d72005-03-03 09:24:38 +00002782- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2783
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002784- Bug #1124295: the __name__ attribute of file objects was
2785 inadvertently made inaccessible in restricted mode.
2786
Tim Petersecc6e6a2005-07-10 22:30:55 +00002787- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002788 an ferror() call.
2789
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002790- min() and max() now support key= arguments with the same meaning as in
2791 list.sort().
2792
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002793- The peephole optimizer now performs simple constant folding in expressions:
2794 (2+3) --> (5).
2795
Raymond Hettingera422c342005-01-11 03:03:27 +00002796- set and frozenset objects can now be marshalled. SF #1098985.
2797
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002798- Bug #1077106: Poor argument checking could cause memory corruption
2799 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002800
Jeremy Hyltonab630502005-02-04 18:44:06 +00002801- The parser did not complain about future statements in illegal
2802 positions. It once again reports a syntax error if a future
2803 statement occurs after anything other than a doc string.
2804
Neil Schemenauercf52c072005-08-12 17:34:58 +00002805- Change the %s format specifier for str objects so that it returns a
2806 unicode instance if the argument is not an instance of basestring and
2807 calling __str__ on the argument returns a unicode instance.
2808
Tim Petersf4e69282006-02-27 17:15:31 +00002809- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2810 current thread state when the auto-GIL-state machinery knows about
2811 it (since the thread state is being deleted, continuing to remember it
2812 can't help, but can hurt if another thread happens to get created with
2813 the same thread id).
2814
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002815Extension Modules
2816-----------------
2817
Georg Brandl43f08a82006-03-31 18:01:16 +00002818- Patch #1380952: fix SSL objects timing out on consecutive read()s
2819
Neal Norwitz05a45592006-03-20 06:30:08 +00002820- Patch #1309579: wait3 and wait4 were added to the posix module.
2821
Anthony Baxterfa869072006-03-20 05:21:58 +00002822- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2823 In addition, the existing ulaw code was updated.
2824
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002825- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002826 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002827
Neal Norwitz10be10c2006-03-16 06:50:13 +00002828- Everything under lib-old was removed. This includes the following modules:
2829 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002830 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002831 util, whatsound, whrandom, zmod
2832
2833- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2834
2835- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002836 is deprecated. The undocumented re.engine variable no longer exists.
2837
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002838- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2839 SS2 (single-shift 2) escape sequences correctly.
2840
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002841- The unicodedata module was updated to the 4.1 version of the Unicode
2842 database. The 3.2 version is still available as unicodedata.db_3_2_0
2843 for applications that require this specific version (such as IDNA).
2844
Neal Norwitzb62c4332006-03-04 18:35:47 +00002845- The timing module is no longer built by default. It was deprecated
2846 in PEP 4 in Python 2.0 or earlier.
2847
Guido van Rossum1968ad32006-02-25 22:38:04 +00002848- Patch 1433928: Added a new type, defaultdict, to the collections module.
2849 This uses the new __missing__ hook behavior added to dict (see above).
2850
Georg Brandldbd83392006-02-20 09:42:33 +00002851- Bug #854823: socketmodule now builds on Sun platforms even when
2852 INET_ADDRSTRLEN is not defined.
2853
Georg Brandlf4f44152006-02-18 22:29:33 +00002854- Patch #1393157: os.startfile() now has an optional argument to specify

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00003005- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
3006 been renamed to have only a single underscore prefix. This was done to
3007 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003008
Nick Coghlan43832302006-04-23 17:04:07 +00003009- PEP 338: new module runpy defines a run_module function to support
3010 executing modules which provide access to source code or a code object
3011 via the PEP 302 import mechanisms.
3012
Anthony Baxter93f5b932006-04-03 08:05:07 +00003013- The email module's parsedate_tz function now sets the daylight savings

3021 in attribute values.
3022
Anthony Baxterc51ee692006-04-01 00:57:31 +00003023- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00003024 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00003025 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00003026 module will not be built.
3027
Tim Petersc17976e2006-04-01 00:26:53 +00003028- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
3029 aren't officially supported here, and trying to use them will probably
3030 raise an exception some day. But dicts have been allowed, and "mostly
3031 worked", so support for them won't go away without warning.
3032
Georg Brandl338ef7d2006-03-31 18:42:16 +00003033- Bug #1445068: getpass.getpass() can now be given an explicit stream
3034 argument to specify where to write the prompt.
3035

3051
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00003052- email 4.0 package now integrated. This is largely the same as the email 3.0
3053 package that was included in Python 2.3, except that PEP 8 module names are
3054 now used (e.g. mail.message instead of email.Message). The MIME classes
3055 have been moved to a subpackage (e.g. email.mime.text instead of
3056 email.MIMEText). The old names are still supported for now. Several
3057 deprecated Message methods have been removed and lots of bugs have been
3058 fixed. More details can be found in the email package documentation.
3059
Walter Dörwald40108c92006-03-27 08:15:44 +00003060- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
3061 (a subclass of tuple) that provides incremental decoders and encoders
3062 (a way to use stateful codecs without the stream API). Python functions
3063 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
3064 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
3065 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00003067- Patch #1359365: Calling next() on a closed StringIO.String object raises
3068 a ValueError instead of a StopIteration now (like file and cString.String do).
3069 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
3070 called before (like file and StringIO.StringIO do).

3138
Neal Norwitz338e7862005-12-23 21:27:46 +00003139- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
3140 LoadError as documented, instead of IOError. For compatibility,
3141 LoadError subclasses IOError.
3142
Brett Cannon3cbd0382005-12-16 22:49:23 +00003143- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00003144 SHA1, 224, 256, 384, and 512. Note that recent developments make the
3145 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
3146 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
3147 Ronald L. Rivest offered this advice for Python:
3148
3149 "The consensus of researchers in this area (at least as
3150 expressed at the NIST Hash Function Workshop 10/31/05),
3151 is that SHA-256 is a good choice for the time being, but
3152 that research should continue, and other alternatives may
3153 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00003154
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00003155- Added a subset of Fredrik Lundh's ElementTree package. Available

3208 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00003209 correct line numbers for decoding errors in source code.

3232 to W3C name (404 -> 'Not Found'). RFE #1216944.
3233
Georg Brandl9e43acf2005-07-04 17:16:07 +00003234- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
3235 as this can cause problems with apps closing all file descriptors.

3248 Bug #1224621.
3249
Raymond Hettinger68c04532005-06-10 11:05:19 +00003250- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00003251 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00003252 the generate_tokens() function now accepts a callable argument that
3253 terminates by raising StopIteration.
3254
Georg Brandl9166e1a2005-06-04 09:20:03 +00003255- Bug #1196315: fix weakref.WeakValueDictionary constructor.

3259
Skip Montanaro174dd222005-05-14 20:54:16 +00003260- Patch #1120353: The xmlrpclib module provides better, more transparent,

3263 class at all.
3264
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00003265- distutils.commands.upload was added to support uploading distribution

3269 them to PyPI.
3270
Raymond Hettinger267b8682005-03-27 10:47:39 +00003271- decimal operator and comparison methods now return NotImplemented
3272 instead of raising a TypeError when interacting with other types. This
3273 allows other classes to implement __radd__ style methods and have them
3274 work as expected.
3275
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003276- Bug #1163325: Decimal infinities failed to hash. Attempting to
3277 hash a NaN raised an InvalidOperation instead of a TypeError.
3278
Tim Petersecc6e6a2005-07-10 22:30:55 +00003279- Patch #918101: Add tarfile open mode r|* for auto-detection of the

3313
Guido van Rossumd0641422005-02-03 15:01:24 +00003314- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3315 disables recursive traversal through instance attributes, which can
3316 be exploited in various ways.
3317
Tim Peterse3547fd2005-12-16 23:13:57 +00003318- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003319 flags on the HTTP listening socket.
3320
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003321- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3322 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3323
Fred Drakefbdeaad2006-07-29 16:56:15 +00003324- Patches #893642, #1039083: add allow_none, encoding arguments to
3325 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003326

Thomas Hellerd6c6e222005-01-20 19:20:16 +00003329- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3330
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003331- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3332
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003333- Enhancements to the csv module:
3334
3335 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003336 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003337 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003338 + Dialect parameter parsing has been re-implemented to improve error
3339 reporting.
3340 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3341 dictates.
3342 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003343 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003344 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003345 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3346 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003347 + reader now allows \r characters to be quoted (previously it only allowed
3348 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003349 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003350 + Dialect classes passed to the module are no longer instantiated by
3351 the module before being parsed (the former validation scheme required
3352 this, but the mechanism was unreliable).
3353 + The dialect registry now contains instances of the internal
3354 C-coded dialect type, rather than references to python objects.
3355 + the internal c-coded dialect type is now immutable.
3356 + register_dialect now accepts the same keyword dialect specifications
3357 as the reader and writer, allowing the user to register dialects
3358 without first creating a dialect class.
3359 + a configurable limit to the size of parsed fields has been added -
3360 previously, an unmatched quote character could result in the entire
3361 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003362 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003363 the parser field size limit (returning the former limit). The initial
3364 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003365 + A line_num attribute has been added to the reader object, which tracks
3366 the number of lines read from the source iterator. This is not
3367 the same as the number of records returned, as records can span
3368 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003369 + reader and writer objects were not being registered with the cyclic-GC.
3370 This has been fixed.
3371
Brett Cannone6539c42005-01-08 02:43:53 +00003372- _DummyThread objects in the threading module now delete self.__block that is
3373 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3374 lock primitives tend to be limited in number and thus should not be wasted on
3375 a _DummyThread object. Fixes bug #1089632.
3376
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003377- The imghdr module now detects Exif files.
3378
Raymond Hettinger6065d322004-12-20 23:51:53 +00003379- StringIO.truncate() now correctly adjusts the size attribute.
3380 (Bug #951915).
3381
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003382- locale.py now uses an updated locale alias table (built using
3383 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3384 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003385 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003386
Raymond Hettinger3557f422004-12-07 12:02:02 +00003387- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3388
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003389- the pickle module no longer accepts the deprecated None option in the
3390 args tuple returned by __reduce__().
3391
Brett Cannon84667c02004-12-07 03:25:18 +00003392- optparse now optionally imports gettext. This allows its use in setup.py.
3393
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003394- the pickle module no longer uses the deprecated bin parameter.
3395
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003396- the shelve module no longer uses the deprecated binary parameter.
3397
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003398- the pstats module no longer uses the deprecated ignore() method.
3399
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003400- the filecmp module no longer uses the deprecated use_statcache argument.
3401
Raymond Hettinger664347b2004-12-04 21:21:53 +00003402- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3403 extended or overridden by subclasses. Formerly, the subclassed method would
3404 be ignored by the rest of the module. (Bug #1078905).
3405
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003406- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003407 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003408
Walter Dörwald36733692004-12-22 12:50:50 +00003409- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3410 once when a size argument is given. This prevents a buffer overflow in the
3411 tokenizer with very long source lines.
3412
Barry Warsaw538561e2006-01-01 21:48:54 +00003413- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3414 immediately after creating the object, without any intervening
3415 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003416
Skip Montanaro05885812005-01-16 20:48:27 +00003417- The reconvert.quote function can now emit triple-quoted strings. The
3418 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003419
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003420- ``UserString.MutableString`` now supports negative indices in
3421 ``__setitem__`` and ``__delitem__``
3422
Greg Ward40407942005-03-05 02:53:17 +00003423- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3424 correctly.
3425
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003426- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3427 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3428 character even if the user has passed a size parameter to get a proper
3429 line ending. Remove the special handling of a "\r\n" that has been split
3430 between two lines.
3431
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003432- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3433 about illegal code points. The codec now supports PEP 293 style error
3434 handlers.
3435
Walter Dörwald78a78b02005-09-01 12:04:29 +00003436- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003437 from the input stream, so that the output is a byte string in the correct
3438 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003439
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003440- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3441 considering it exactly like a '*'.
3442
Walter Dörwald007f8df2005-10-09 19:42:27 +00003443- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3444 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003445
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003446- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3447
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003448- Patch #1413711: Certain patterns of differences were making difflib
3449 touch the recursion limit.
3450
Walter Dörwald58917a62006-03-31 15:26:22 +00003451- Bug #947906: An object oriented interface has been added to the calendar
3452 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003453 called as a script (e.g. via ``python -mcalendar``). Localized month and
3454 weekday names can be ouput (even if an exotic encoding is used) using
3455 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003456
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003457Build
3458-----
3459
Neal Norwitz602d3392006-03-31 08:21:40 +00003460- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3461 by using -mieee gcc option.
3462
Martin v. Löwis86d66262006-02-17 08:40:11 +00003463- Patch #1432345: Make python compile on DragonFly.
3464
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003465- Build support for Win64-AMD64 was added.
3466
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003467- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3468
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003469- Patch #881820: look for openpty and forkpty also in libbsd.
3470
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003471- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3472 The zlib module is now builtin on Windows.
3473
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003474- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3475
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003476- Bug #1189330: configure did not correctly determine the necessary
3477 value of LINKCC if python was built with GCC 4.0.
3478
Trent Mick8321b422005-07-26 02:29:21 +00003479- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3480 vulnerability in zlib 1.2.1 and 1.2.2.
3481
Brett Cannon08cd5982005-04-24 22:26:38 +00003482- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3483 flags that change binary compatibility. Changes were also made to
3484 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003485 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003486
Bob Ippolitoed233462005-03-29 13:47:59 +00003487- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3488 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3489 no longer exists). This configure patch makes things right.
3490
Martin v. Löwise2713be2005-03-08 15:03:08 +00003491- Bug #1158607: Build with --disable-unicode again.
3492
Brett Cannon46d96232005-02-16 00:07:19 +00003493- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3494 defined. Discovered as a result of not being able to build on OS X.
3495
Brett Cannon516592f2004-12-07 00:42:59 +00003496- setup.py now uses the directories specified in LDFLAGS using the -L option
3497 and in CPPFLAGS using the -I option for adding library and include
3498 directories, respectively, for compiling extension modules against. This has
3499 led to the core being compiled using the values in CPPFLAGS. It also removes
3500 the need for the special-casing of both DarwinPorts and Fink for darwin since
3501 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3502 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3503 Fink, ``-I/opt/local/include`` for DarwinPorts).
3504
Brett Cannon43802422005-02-10 20:48:03 +00003505- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3506 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3507 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3508 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003510C API
3511-----
3512
Tim Petersc9d78aa2006-03-26 23:27:58 +00003513- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3514 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3515 is obtained via the ``PyObject_`` family, it must be released via the
3516 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3517 always been officially true, but when Python's small-object allocator was
3518 introduced, an attempt was made to cater to a few extension modules
3519 discovered at the time that obtained memory via ``PyObject_New`` but
3520 released it via ``PyMem_DEL``. It's years later, and if such code still
3521 exists it will fail now (probably with segfaults, but calling wrong
3522 low-level memory management functions can yield many symptoms).
3523
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003524- Added a C API for set and frozenset objects.
3525
Raymond Hettinger66517482004-12-03 11:45:13 +00003526- Removed PyRange_New().
3527
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003528- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3529 mapping argument now. This string is used as a mapping table. Byte values
3530 greater than the length of the string and 0xFFFE are treated as undefined
3531 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003538
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003539- Patch #1276356: New resource "urlfetch" is implemented. This enables
3540 even impatient people to run tests that require remote files.
