11
12Core and builtins
13-----------------
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000014
Benjamin Peterson6f08e852008-11-03 15:19:35 +000015- Issue #4048: The parser module now correctly validates relative imports.
16
Amaury Forgeot d'Arc3b335ff2008-10-30 21:40:05 +000017- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
18 method does not return iterators for the 4th and 5th items.
19
Amaury Forgeot d'Arcb50f9922008-09-26 22:46:01 +000020- Issue #3967: Fixed a crash in the count() and find() methods of string-like
21 objects, when the "start" parameter is a huge value.
22
Benjamin Petersond1c7d072008-09-25 20:46:05 +000023- Issue #3936: The parser warnings for using "as" and "with" as variable names
24 didn't fire after import statements.
25
Amaury Forgeot d'Arcafa0d582008-09-01 20:05:08 +000026- Issue #3751: str.rpartition would perform a left-partition when called with
27 a unicode argument.
28
Georg Brandl45c33ce2008-08-11 09:13:26 +000029- Issue #3537: Fix an assertion failure when an empty but presized dict
30 object was stored in the freelist.
31
Neal Norwitz4f3be8a2008-07-31 17:08:14 +000032- Apply security patches from Apple.
33
Neal Norwitz83ac0142008-07-28 05:06:20 +000034- Issue #2620: Overflow checking when allocating or reallocating memory
35 was not always being done properly in some python types and extension
36 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
37 all been updated to perform better checks and places in the code that
38 would previously leak memory on the error path when such an allocation
39 failed have been fixed.
40
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +000041- Issue #2242: Fix a crash when decoding invalid utf-7 input on certain
42 Windows / Visual Studio versions.
43
Mark Dickinsonab396e02008-07-16 11:04:17 +000044- Issue #3360: Fix incorrect parsing of '020000000000.0', which
45 produced a ValueError instead of giving the correct float.
46
Amaury Forgeot d'Arcceda6a62008-07-01 20:52:56 +000047- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
48 set to a custom object whose write() method happens to install
49 another file in sys.stdout.
50
Amaury Forgeot d'Arcb15bdf72008-07-01 20:59:49 +000051- Issue #3088: Corrected a race condition in classes derived from
52 threading.local: the first member set by a thread could be saved in
53 another thread's dictionary.
54
Amaury Forgeot d'Arc3255e132008-06-16 19:22:42 +000055- Issue #3100: Corrected a crash on deallocation of a subclassed weakref which
56 holds the last (strong) reference to its referent.
57
Guido van Rossumaa975432008-04-10 22:43:58 +000058- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
59 having a self-referential tuple, which is possible from C code. Nor did
60 object's tp_str consider that a type's tp_str could do something that could
61 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
62 respectively, fixed the issues. (Backport of r58288 from trunk.)
63
Georg Brandld9f1da02008-03-29 01:50:46 +000064- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
65 cannot be executed.
66
Amaury Forgeot d'Arc8432d862008-03-28 20:45:42 +000067- The compilation of a class nested in another class used to leak one
68 reference on the outer class name.
69
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000070- Issue #1477: With narrow Unicode builds, the unicode escape sequence
71 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
72 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
73 UTF-16 surrogates are generated in this case, like normal unicode literals
74 and the 'unicode-escape' codec.
75
Neal Norwitzb3635f92008-03-18 04:17:36 +000076- Issue #2321: use pymalloc for unicode object string data to reduce
77 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +000078
Sean Reifscheider4af861c2008-03-20 17:39:31 +000079- Issue #2238: Some syntax errors in *args and **kwargs expressions could give
80 bogus error messages.
81
Gregory P. Smith14acde32008-04-09 23:41:13 +000082- Issue #2587: In the C API, PyString_FromStringAndSize() takes a signed size
83 parameter but was not verifying that it was greater than zero. Values
84 less than zero will now raise a SystemError and return NULL to indicate a
85 bug in the calling C code.
86
Gregory P. Smith9aa040d2008-06-02 00:07:25 +000087- Issue #2588, #2589: Fix potential integer underflow and overflow
88 conditions in the PyOS_vsnprintf C API function.
89
Gregory P. Smithcae7f882008-09-07 06:44:12 +000090- Issue #1204: The configure script now tests for additional libraries
91 that may be required when linking against readline. This fixes issues
92 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
Georg Brandld9f1da02008-03-29 01:50:46 +000093
Gregory P. Smitha7a94a02008-09-22 00:22:44 +000094- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
95 library targets in the Makefile.

105
Brett Cannon70f1192d2008-09-29 03:57:24 +0000106- Issue #3895: _lsprof could be crashed with an external timer that did not
107 return a float when a Profiler object is garbage collected.
108

115 its symbolic link.
116
Thomas Heller275e2292008-08-19 17:17:37 +0000117- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
118 api functions without holding the GIL, which could lead to a fatal
119 error when they failed.
120
Amaury Forgeot d'Arc22679b82008-08-18 19:33:42 +0000121- Issue #2234: distutils failed for some versions of the cygwin compiler. The
122 version reported by these tools does not necessarily follow the python
123 version numbering scheme, so the module is less strict when parsing it.
124
Hirokazu Yamamoto1d63a452008-08-17 09:49:10 +0000125- Issue #2222: Fixed reference leak when occured os.rename()
126 fails unicode conversion on 2nd parameter. (windows only)

Amaury Forgeot d'Arc198e3532008-03-27 23:41:59 +0000146- Issue #2495: tokenize.untokenize now inserts a space between two consecutive
147 string literals; previously, ["" ""] was rendered as [""""], which is
148 incorrect python code.
149
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +0000150- Issue #2482: Make sure that the coefficient of a Decimal is always
151 stored as a str instance, not as a unicode instance. This ensures
152 that str(Decimal) is always an instance of str. This fixes a
153 regression from Python 2.5.1 to Python 2.5.2.
154
Mark Dickinson26c25d92008-03-25 14:35:25 +0000155- Issue #2478: fix failure of decimal.Decimal(0).sqrt()

169 large messages.
170
Andrew M. Kuchling664553a2008-02-23 19:30:59 +0000171- Bug #1389051, 1092502: fix excessively large memory allocations when
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000172 calling .read() on a socket object wrapped with makefile().
Andrew M. Kuchling664553a2008-02-23 19:30:59 +0000173

178 stdout and stderr fds rather than leaving them open until the
179 instance is destroyed.
180

272-----------------
273
Martin v. Löwis73c01d42008-02-14 11:26:18 +0000274- Added checks for integer overflows, contributed by Google. Some are
275 only available if asserts are left in the code, in cases where they
276 can't be triggered from Python code.
277
Amaury Forgeot d'Arc3e5f8a62008-02-08 01:05:21 +0000278- Issue #2045: Fix an infinite recursion triggered when printing a subclass of
279 collections.defaultdict, if its default_factory is set to a bound method.
280
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000281- Issue #1920: "while 0" statements were completely removed by the compiler,
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000282 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000283 the condition is false. Now the compiler correctly emits bytecode for the
284 "else" suite.
285
Guido van Rossumd933e0a2008-01-24 18:28:37 +0000286- A few crashers fixed: weakref_in_del.py (issue #1377858);

293
Christian Heimesd2f4cb82008-01-23 14:20:41 +0000294- Bug #1915: Python compiles with --enable-unicode=no again. However
295 several extension methods and modules do not work without unicode
296 support.
297
Mark Dickinson2bebadf2008-01-21 21:54:47 +0000298- Issue #1678380: distinction between 0.0 and -0.0 was lost during constant
299 folding optimization. This was a regression from Python 2.4.
300
Georg Brandl78d50cc2008-01-21 18:36:54 +0000301- Issue #1882: when compiling code from a string, encoding cookies in the

869 be equal to calling getsockname() on the server's socket. Fixed by patch
870 #1545011.
871
Thomas Heller8bf469d2007-03-09 20:48:57 +0000872- Bug #1651235: When a tuple was passed to a ctypes function call,
873 Python would crash instead of raising an error.

881
Georg Brandld59ea472007-03-08 18:37:35 +0000882- unittest now verifies more of its assumptions. In particular, TestCase
883 and TestSuite subclasses (not instances) are no longer accepted in
884 TestSuite.addTest(). This should cause no incompatibility since it
885 never made sense with ordinary subclasses -- the failure just occurred
886 later, with a more cumbersome exception.

Brett Cannon19d76c52006-09-09 07:18:44 +00001105- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

Neal Norwitzff4b63b2006-08-04 04:50:21 +00001240
1241Core and builtins
1242-----------------
1243
Neal Norwitz24b6f202006-09-05 04:43:56 +00001244- Fix infinite recursion when subclassing long and overriding __hash__.
1245
1246- Fix concatenation (+=) of long strings.
1247
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001248- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001249 compared equal or unequal to a string and a UnicodeDecodeError
1250 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001251
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001252 Instead, the equal (==) and unequal (!=) comparison operators will
1253 now issue a UnicodeWarning and interpret the two objects as
1254 unequal. The UnicodeWarning can be filtered as desired using
1255 the warning framework, e.g. silenced completely, turned into an
1256 exception, logged, etc.
1257
1258 Note that compare operators other than equal and unequal will still
1259 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001260
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001261- Fix segfault when doing string formatting on subclasses of long.
1262
1263- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1264 with new-style classes.
1265
1266- Fix bug related to __len__ functions returning negative values with
1267 classic classes.
1268
1269- Patch #1538606, Fix __index__() clipping. There were some problems
1270 discovered with the API and how integers that didn't fit into Py_ssize_t
1271 were handled. This patch attempts to provide enough alternatives
1272 to effectively use __index__.
1273
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001274- Bug #1536021: __hash__ may now return long int; the final hash
1275 value is obtained by invoking hash on the long int.
1276
Thomas Hellerab1049c2006-08-08 17:37:00 +00001277- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1278
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001279- Bug #1535165: fixed a segfault in input() and raw_input() when
1280 sys.stdin is closed.
1281
Thomas Heller74d36f02006-08-04 18:17:40 +00001282- On Windows, the PyErr_Warn function is now exported from
1283 the Python dll again.
1284
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001285- Bug #1191458: tracing over for loops now produces a line event
1286 on each iteration. Fixing this problem required changing the .pyc
1287 magic number. This means that .pyc files generated before 2.5c1
1288 will be regenerated.
1289
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001290- Bug #1333982: string/number constants were inappropriately stored
1291 in the byte code and co_consts even if they were not used, ie
1292 immediately popped off the stack.
1293
Georg Brandle9462c72006-08-04 18:03:37 +00001294- Fixed a reference-counting problem in property().

1297Library
1298-------
1299
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001300- Fix a bug in the ``compiler`` package that caused invalid code to be
1301 generated for generator expressions.
1302
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001303- The distutils version has been changed to 2.5.0. The change to
1304 keep it programmatically in sync with the Python version running
1305 the code (introduced in 2.5b3) has been reverted. It will continue
1306 to be maintained manually as static string literal.
1307
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001308- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001309 and this cannot be converted to the required C type, an exception is
1310 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001311 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001312
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001313- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001314 an exception.
1315
Tim Peterscbdd3502006-09-05 01:47:53 +00001316- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001317 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001318 workarounds for clocks with low resolution, to stop the code yielding
1319 duplicate UUIDs.
1320
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001321- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1322 before raising SystemExit, allowing IDLE to honor quit() and exit().
1323
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001324- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1325
Georg Brandl7a1af772006-08-14 21:55:28 +00001326- Patch #1536071: trace.py should now find the full module name of a
1327 file correctly even on Windows.
1328
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001329- logging's atexit hook now runs even if the rest of the module has
1330 already been cleaned up.
1331
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001332- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001333
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001334- Bug #1531405, format_exception no longer raises an exception if
1335 str(exception) raised an exception.
1336
Neil Schemenauer06ded092006-08-04 16:20:30 +00001337- Fix a bug in the ``compiler`` package that caused invalid code to be
1338 generated for nested functions.

1349 raises the correct exceptions.
1350
Thomas Heller1ce433e2006-08-14 16:20:04 +00001351- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1352 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1353
Thomas Heller86720042006-08-14 11:17:48 +00001354- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1355 uses the _as_parameter_ attribute when objects are passed to foreign
1356 function calls. The ctypes version number was changed to 1.0.1.
1357
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001358- Bug #1530559, struct.pack raises TypeError where it used to convert.
1359 Passing float arguments to struct.pack when integers are expected
1360 now triggers a DeprecationWarning.

Neal Norwitza1f10902006-07-12 07:28:29 +00001409
1410Core and builtins
1411-----------------
1412
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001413- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001414 returned a long (see PEP 353).
1415
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001416- Bug #1515471: string.replace() accepts character buffers again.
1417
Neal Norwitz07aadb12006-07-30 06:55:48 +00001418- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1419 This provides the proper warning for struct.pack().
1420 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1421
Neal Norwitz0d62a062006-07-30 06:53:31 +00001422- Patch #1531113: Fix augmented assignment with yield expressions.
1423 Also fix a SystemError when trying to assign to yield expressions.
1424
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001425- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1426 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1427 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1428 excessive filesystem operations during imports.
1429
Tim Petersbc24eee2006-07-27 01:14:53 +00001430- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1431 operations on signed longs that are formally undefined by C.
1432 Unfortunately, at least one compiler now cares about that, so complicated
1433 the code to make that compiler happy again.
1434
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001435- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1436
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001437- Patch #1232023: Stop including current directory in search
1438 path on Windows.
1439
Neal Norwitze1fdb322006-07-21 05:32:28 +00001440- Fix some potential crashes found with failmalloc.
1441
Neal Norwitze7563102006-07-17 01:00:16 +00001442- Fix warnings reported by Klocwork's static analysis tool.
1443
Neal Norwitz84be93b2006-07-16 01:50:38 +00001444- Bug #1512814, Fix incorrect lineno's when code within a function
1445 had more than 255 blank lines.
1446
Georg Brandl9dceedb2006-07-12 15:31:17 +00001447- Patch #1521179: Python now accepts the standard options ``--help`` and
1448 ``--version`` as well as ``/?`` on Windows.
1449
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001450- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001451 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001452 This means that .pyc files generated before 2.5b3 will be regenerated.

Tim Peters112aad32006-07-19 00:03:19 +00001454- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001455 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001456 new ``sys._current_frames()`` returns a dictionary with one entry,
1457 mapping the faux "thread id" 0 to the current frame.

1463-------
1464
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001465- Correction of patch #1455898: In the mbcs decoder, set final=False
1466 for stream decoder, but final=True for the decode function.
1467
Georg Brandl07fec3a2006-08-01 18:49:24 +00001468- os.urandom no longer masks unrelated exceptions like SystemExit or
1469 KeyboardInterrupt.
1470
Tim Peters4643c2f2006-08-10 22:45:34 +00001471- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001472 shutil.copytree on Windows
1473
Georg Brandle34ac7c2006-07-30 11:07:23 +00001474- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1475 refers to file descriptors, not file objects.
1476
Tim Peterscbdd3502006-09-05 01:47:53 +00001477- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001478 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001479 #1513611, and probably others.
1480
Georg Brandledd9b0d2006-07-29 09:33:26 +00001481- Bug #1441397: The compiler module now recognizes module and function
1482 docstrings correctly as it did in Python 2.4.
1483
Tim Peters6f681472006-07-27 23:44:37 +00001484- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1485 lost that tests are sorted by name before being run. This rarely
1486 matters for well-written tests, but can create baffling symptoms if
1487 side effects from one test to the next affect outcomes. ``DocTestFinder``
1488 has been changed to sort the list of tests it returns.
1489
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001490- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001491 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001492
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001493- Bug #978833: Really close underlying socket in _socketobject.close.
1494
Georg Brandldb232dc2006-08-20 13:15:43 +00001495- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1496 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001497
Georg Brandlcf0c1722006-07-26 07:23:32 +00001498- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1499 to recursive calls and call it with the failing package name.
1500
Martin v. Löwis0b483032006-07-25 09:53:12 +00001501- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1502
Georg Brandlc13c34c2006-07-24 14:09:56 +00001503- Patch #1515343: Fix printing of deprecated string exceptions with a
1504 value in the traceback module.
1505
Greg Ward48fae7a2006-07-23 16:05:51 +00001506- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1507
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001508- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1509
Brett Cannoncaebe222006-07-18 04:41:36 +00001510- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1511 argument tuple. For arguments where zero is illegal, the value is forced to
1512 the minimum value that is correct. This is to support an undocumented but
1513 common way people used to fill in inconsequential information in the time
1514 tuple pre-2.4.
1515
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001516- Patch #1220874: Update the binhex module for Mach-O.
1517
Barry Warsawb110bad2006-07-21 14:51:07 +00001518- The email package has improved RFC 2231 support, specifically for
1519 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1520 (name*0=<blah>) parameter continuations. This may change the types of
1521 values returned from email.message.Message.get_param() and friends.
1522 Specifically in some cases where non-encoded continuations were used,
1523 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1524 will just return the string (since non-encoded continuations don't have
1525 charset and language parts).
1526
1527 Also, whereas % values were decoded in all parameter continuations, they are
1528 now only decoded in encoded parameter parts.
1529
Ronald Oussoren3075e162006-07-25 20:28:55 +00001530- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1531
1532- Bug #1517996: IDLE now longer shows the default Tk menu when a
1533 path browser, class browser or debugger is the frontmost window on MacOS X
1534
Barry Warsaw00decd72006-07-27 23:43:15 +00001535- Patch #1520294: Support for getset and member descriptors in types.py,
1536 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1537 of an object against these built-in types and more importantly, for getting
1538 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001541Extension Modules
1542-----------------
1543
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001544- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1545 a socket operation on a socket with a timeout, the exception will be
1546 caught correctly. Previously, the exception was not caught.
1547
Thomas Heller1393d6a2006-07-28 21:43:20 +00001548- Patch #1529514: The _ctypes extension is now compiled on more
1549 openbsd target platforms.
1550
Tim Peters9cab5932006-07-28 00:30:00 +00001551- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1552 a memory leak, affecting pickles and deep copies.
1553
Tim Petersbc24eee2006-07-27 01:14:53 +00001554- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001555 Paul Eggert.
1556
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001557- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1558
Thomas Hellerce049a02006-07-14 17:51:14 +00001559- Patch #1521817: Index range checking on ctypes arrays containing
1560 exactly one element enabled again. This allows iterating over these
1561 arrays, without the need to check the array size before.
1562
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001563- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001564 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001565 /dev/null in certain cases; this is now fixed.
1566
Thomas Heller47d7a062006-07-12 08:43:47 +00001567- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1568 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001569
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001570- Because of a misspelled preprocessor symbol, ctypes was always
1571 compiled without thread support; this is now fixed.
1572
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001573- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1574 methods now allow their database parameter to be None as the
1575 sleepycat API allows.
1576
Matt Flemingec926502006-07-28 11:27:27 +00001577- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1578 bluetooth API compared with Linux and FreeBSD.
1579
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001580Tests
1581-----
1582
1583- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1584 how long the test file should take to play. Now accepts taking 2.93 secs
1585 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1586
Georg Brandl4793aa32006-07-28 18:31:39 +00001587- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1588 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1589 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001596Mac
1597---
1598
1599- PythonLauncher now works correctly when the path to the script contains
1600 characters that are treated specially by the shell (such as quotes).
1601
1602- Bug #1527397: PythonLauncher now launches scripts with the working directory
1603 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001604 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001605 expect.

1614-----------------
1615
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001616- Bug #1441486: The literal representation of -(sys.maxint - 1)
1617 again evaluates to a int object, not a long.
1618
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001619- Bug #1501934: The scope of global variables that are locally assigned
1620 using augmented assignment is now correctly determined.
1621
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001622- Bug #927248: Recursive method-wrapper objects can now safely
1623 be released.
1624
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001625- Bug #1417699: Reject locale-specific decimal point in float()
1626 and atof().
1627
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001628- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1629 omit a default "error" argument for NULL pointer. This allows
1630 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001631
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001632- Bug #1519018: 'as' is now validated properly in import statements.
1633
Neal Norwitz28746ab2006-07-09 22:14:42 +00001634- On 64 bit systems, int literals that use less than 64 bits are
1635 now ints rather than longs.
1636
Neal Norwitzed657552006-07-10 00:04:44 +00001637- Bug #1512814, Fix incorrect lineno's when code at module scope
1638 started after line 256.
1639
Tim Peters32a83612006-07-10 21:08:24 +00001640- New function ``sys._current_frames()`` returns a dict mapping thread
1641 id to topmost thread stack frame. This is for expert use, and is
1642 especially useful for debugging application deadlocks. The functionality
1643 was previously available in Fazal Majid's ``threadframe`` extension
1644 module, but it wasn't possible to do this in a wholly threadsafe way from
1645 an extension.

1654
Tim Peters32a83612006-07-10 21:08:24 +00001655- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001656 environment variable to be set in order to the SDK environment
1657 for finding the compiler, include files, etc.

1662
Thomas Woutersadd19112006-07-05 11:03:49 +00001663- string.Template() now correctly handles tuple-values. Previously,
1664 multi-value tuples would raise an exception and single-value tuples would
1665 be treated as the value they contain, instead.
1666
Martin v. Löwisede77f52006-07-03 13:01:35 +00001667- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1669
Martin v. Löwis45482392006-07-03 12:28:58 +00001670- Bug #1267547: Put proper recursive setup.py call into the
1671 spec file generated by bdist_rpm.
1672
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001673- Bug #1514693: Update turtle's heading when switching between
1674 degrees and radians.
1675
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001676- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001677 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001678
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001679- Bug #1514703: Only setup canvas window in turtle when the canvas
1680 is created.
1681
Martin v. Löwis7596e832006-07-01 15:33:37 +00001682- Bug #1513223: .close() of a _socketobj now releases the underlying
1683 socket again, which then gets closed as it becomes unreferenced.
1684
Fred Drake10497c82006-06-29 02:57:48 +00001685- Bug #1504333: Make sgmllib support angle brackets in quoted
1686 attribute values.
1687
1688- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1689 sgmllib ('[' and ']' were not accepted).
1690
Georg Brandl1be63af2006-06-28 20:23:25 +00001691- Fix a bug in the turtle module's end_fill function.
1692
Brett Cannon53ab5b72006-06-22 16:49:14 +00001693- Bug #1510580: The 'warnings' module improperly required that a Warning
1694 category be either a types.ClassType and a subclass of Warning. The proper
1695 check is just that it is a subclass with Warning as the documentation states.
1696
Georg Brandlad29e632006-06-21 17:45:17 +00001697- The compiler module now correctly compiles the new try-except-finally
1698 statement (bug #1509132).
1699
Neal Norwitz60373cd2006-06-22 06:30:50 +00001700- The wsgiref package is now installed properly on Unix.
1701
Vinay Sajip28e57612006-07-01 10:45:20 +00001702- A bug was fixed in logging.config.fileConfig() which caused a crash on
1703 shutdown when fileConfig() was called multiple times.
1704
Gerhard Häring762fbd32006-07-02 17:48:30 +00001705- The sqlite3 module did cut off data from the SQLite database at the first
1706 null character before sending it to a custom converter. This has been fixed
1707 now.

1710-----------------
1711
Tim Peters112aad32006-07-19 00:03:19 +00001712- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1713 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1714 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001715
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001716- Assigning None to pointer type fields in ctypes structures possible
1717 overwrote the wrong fields, this is fixed now.
1718
1719- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1720 on non-Windows platforms.
1721
1722- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1723 integer or long, without range checking.
1724
1725- Patch #1517790: It is now possible to use custom objects in the ctypes
1726 foreign function argtypes sequence as long as they provide a from_param
1727 method, no longer is it required that the object is a ctypes type.
1728
1729- The '_ctypes' extension module now works when Python is configured
1730 with the --without-threads option.
1731
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001732- Bug #1513646: os.access on Windows now correctly determines write
1733 access, again.
1734
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001735- Bug #1512695: cPickle.loads could crash if it was interrupted with
1736 a KeyboardInterrupt.
1737
Neal Norwitza12aa882006-07-06 06:45:08 +00001738- Bug #1296433: parsing XML with a non-default encoding and

1747
Tim Peters32a83612006-07-10 21:08:24 +00001748- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001749 Previously, the slight difference could cause compilation errors of the
1750 'zlib' module on systems with more than one version of zlib.
1751
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001752- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +00001780
Anthony Baxterd1136802006-06-19 12:04:15 +00001781*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001782
1783Core and builtins
1784-----------------
1785
Georg Brandla56b9152006-06-19 06:35:54 +00001786- Patch #1507676: Error messages returned by invalid abstract object operations
1787 (such as iterating over an integer) have been improved and now include the
1788 type of the offending object to help with debugging.
1789
Brett Cannonea3912b2006-06-13 21:46:41 +00001790- Bug #992017: A classic class that defined a __coerce__() method that returned
1791 its arguments swapped would infinitely recurse and segfault the interpreter.
1792
Neal Norwitz909eb122006-06-12 02:13:21 +00001793- Fix the socket tests so they can be run concurrently.
1794
Neal Norwitzb9845e72006-06-12 02:11:18 +00001795- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001796 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001797
Brett Cannon22565aa2006-06-09 22:31:23 +00001798- Bug #532646: object.__call__() will continue looking for the __call__
1799 attribute on objects until one without one is found. This leads to recursion
1800 when you take a class and set its __call__ attribute to an instance of the
1801 class. Originally fixed for classic classes, but this fix is for new-style.
1802 Removes the infinite_rec_3 crasher.
1803
Georg Brandl24250812006-06-09 18:45:48 +00001804- The string and unicode methods startswith() and endswith() now accept
1805 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1806
Brett Cannonde3b0522006-06-08 17:00:45 +00001807- Buffer objects, at the C level, never used the char buffer
1808 implementation even when the char buffer for the wrapped object was
1809 explicitly requested (originally returned the read or write buffer).
1810 Now a TypeError is raised if the char buffer is not present but is
1811 requested.
1812
Georg Brandlddbaa662006-06-04 21:56:52 +00001813- Patch #1346214: Statements like "if 0: suite" are now again optimized
1814 away like they were in Python 2.4.
1815
Georg Brandlb7c8f542006-05-27 12:30:25 +00001816- Builtin exceptions are now full-blown new-style classes instead of
1817 instances pretending to be classes, which speeds up exception handling
1818 by about 80% in comparison to 2.5a2.
1819
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001820- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1821 Unicode 4.1.
1822
Georg Brandlf4ef1162006-05-26 18:03:31 +00001823- Patch #921466: sys.path_importer_cache is now used to cache valid and
1824 invalid file paths for the built-in import machinery which leads to
1825 fewer open calls on startup.
1826
Tim Peters696cf432006-05-24 21:10:40 +00001827- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1828 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1829 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1830 the number of input digits (it was and remains linear-time for bases
1831 2, 4, 8, 16 and 32).
1832
Tim Petersb713ec22006-05-23 18:45:30 +00001833- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1834 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1835 an integer close to ``sys.maxint``. This was repaired by patch
1836 #1335972, which also gives a nice speedup.
1837
Richard Jonescebbefc2006-05-23 18:28:17 +00001838- Patch #1337051: reduced size of frame objects.
1839
1840- PyErr_NewException now accepts a tuple of base classes as its
1841 "base" parameter.
1842
Richard Jones7c88dcc2006-05-23 10:37:38 +00001843- Patch #876206: function call speedup by retaining allocated frame
1844 objects.
1845
Georg Brandl7b90e162006-05-18 07:01:27 +00001846- Bug #1462152: file() now checks more thoroughly for invalid mode
1847 strings and removes a possible "U" before passing the mode to the
1848 C library function.
1849
Neal Norwitz1004a532006-05-15 07:17:23 +00001850- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1851
Neal Norwitz373f0a72006-05-15 07:04:36 +00001852- Bug #1487966: Fix SystemError with conditional expression in assignment
1853
Martin v. Löwis879768d2006-05-11 13:28:43 +00001854- WindowsError now has two error code attributes: errno, which carries
1855 the error values from errno.h, and winerror, which carries the error
1856 values from winerror.h. Previous versions put the winerror.h values
1857 (from GetLastError()) into the errno attribute.
1858
Martin v. Löwis77736712006-05-04 05:51:03 +00001859- Patch #1475845: Raise IndentationError for unexpected indent.
1860
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001861- Patch #1479181: split open() and file() from being aliases for each other.
1862
Tim Peters44bd9862006-06-01 13:49:23 +00001863- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1864 methods were always silently ignored by dictionaries when comparing keys.
1865 They are now passed through (except when using the C API function
1866 ``PyDict_GetItem()``, whose semantics did not change).
1867
1868- Bug #1456209: In some obscure cases it was possible for a class with a
1869 custom ``__eq__()`` method to confuse dict internals when class instances
1870 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1871 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001873Extension Modules
1874-----------------
1875
Trent Mick960a3f82006-06-28 20:30:41 +00001876- Bug #1295808: expat symbols should be namespaced in pyexpat
1877
1878- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1879
Brett Cannon6ee7d012006-06-08 16:23:04 +00001880- Change binascii.hexlify to accept a read-only buffer instead of only a char
1881 buffer and actually follow its documentation.
1882
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001883- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1884
Nick Coghlanc649ec52006-05-29 12:43:05 +00001885- Patch #1478788 (modified version): The functional extension module has
1886 been renamed to _functools and a functools Python wrapper module added.
1887 This provides a home for additional function related utilities that are
1888 not specifically about functional programming. See PEP 309.
1889
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001890- Patch #1493701: performance enhancements for struct module.
1891
Georg Brandl378d5922006-05-17 14:26:50 +00001892- Patch #1490224: time.altzone is now set correctly on Cygwin.
1893
Georg Brandl8d3342b2006-05-16 07:38:27 +00001894- Patch #1435422: zlib's compress and decompress objects now have a
1895 copy() method.
1896
Andrew MacIntyre92913322006-06-13 15:04:24 +00001897- Patch #1454481: thread stack size is now tunable at runtime for thread
1898 enabled builds on Windows and systems with Posix threads support.
1899
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001900- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1901 (up to the system limit of 32K characters).
1902
1903- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1904 As a result, these functions now raise WindowsError instead of OSError.
1905
Tim Peters7a822da2006-05-25 21:50:17 +00001906- ``time.clock()`` on Win64 should use the high-performance Windows
1907 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1908 Windows platforms).
1909
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001910- Calling Tk_Init twice is refused if the first call failed as that
1911 may deadlock.
1912
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001913- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1914 accept it without potentially using an uninitialized pointer.
1915
1916- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1917 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1918 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001919
Gregory P. Smith372b5832006-06-05 18:48:21 +00001920- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001921 [pybsddb project SF patch number 1466734]
1922
Gregory P. Smith372b5832006-06-05 18:48:21 +00001923- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1924 parameter is supplied. [SF pybsddb bug #1477863]
1925
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001926- bsddb: the __len__ method of a DB object has been fixed to return correct
1927 results. It could previously incorrectly return 0 in some cases.
1928 Fixes SF bug 1493322 (pybsddb bug 1184012).
1929
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001930- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1931 aborts the db transaction safely when a modifier callback fails.
1932 Fixes SF python patch/bug #1408584.
1933
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001934- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001935 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001936 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1937 database calls that would previously deadlock. [SF python bug #775414]
1938
Vinay Sajip28e57612006-07-01 10:45:20 +00001939- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001940
Walter Dörwald4994d952006-06-19 08:07:50 +00001941- Patch #1506645: add Python wrappers for the curses functions
1942 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001943

1945-------
1946
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001947- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1948 functions.
1949
Martin v. Löwis3798da02006-06-17 18:44:27 +00001950- Patch #812986: Update turtle output even if not tracing.
1951
Vinay Sajip28e57612006-07-01 10:45:20 +00001952- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001953 Tkinter.BaseWidget.
1954
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001955- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1956
Martin v. Löwis337487e2006-06-17 09:15:14 +00001957- Patch #763580: Add name and value arguments to Tkinter variable
1958 classes.
1959
Georg Brandl83cc0d02006-06-14 08:50:03 +00001960- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1961 mime.types file for determining MIME types.
1962
Georg Brandl2605ca82006-06-14 06:08:31 +00001963- Bug #1339007: Shelf objects now don't raise an exception in their
1964 __del__ method when initialization failed.
1965
Martin v. Löwisd8251432006-06-14 05:21:04 +00001966- Patch #1455898: The MBCS codec now supports the incremental mode for
1967 double-byte encodings.
1968
Tim Peters43898b42006-06-14 04:09:25 +00001969- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1970 guarantee that adjacent triples in the return list always describe
1971 non-adjacent blocks. Previously, a pair of matching blocks could end
1972 up being described by multiple adjacent triples that formed a partition
1973 of the matching pair.
1974
Greg Ward0e0c9f42006-06-11 16:24:11 +00001975- Bug #1498146: fix optparse to handle Unicode strings in option help,
1976 description, and epilog.
1977
Greg Wardd1c797e2006-06-11 14:42:41 +00001978- Bug #1366250: minor optparse documentation error.
1979
Greg Ward7f547402006-06-11 00:40:49 +00001980- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1981 clarify docs.
1982
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001983- The wsgiref package has been added to the standard library.
1984
Nick Coghlan676725d2006-06-08 13:54:49 +00001985- The functions update_wrapper() and wraps() have been added to the functools
1986 module. These make it easier to copy relevant metadata from the original
1987 function when writing wrapper functions.
1988
Tim Petersd6a9eef2006-06-05 01:48:21 +00001989- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1990 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001991
Martin v. Löwis3f767792006-06-04 19:36:28 +00001992- Patch #1359618: Speed up charmap encoder by using a trie structure
1993 for lookup.
1994
Tim Petersd609b1a2006-06-02 23:22:51 +00001995- The functions in the ``pprint`` module now sort dictionaries by key
1996 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1997 if and only if its display required more than one line, although that
1998 wasn't documented. The new behavior increases predictability; e.g.,
1999 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2000
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002001- Patch #1497027: try HTTP digest auth before basic auth in urllib2
2002 (thanks for J. J. Lee).
2003
Georg Brandl2b330372006-05-28 20:23:12 +00002004- Patch #1496206: improve urllib2 handling of passwords with respect to
2005 default HTTP and HTTPS ports.
2006
George Yoshidaf3c65de2006-05-28 16:39:09 +00002007- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
2008
Bob Ippolito7298f272006-05-23 18:43:47 +00002009- Patch #1281707: speed up gzip.readline.
2010
Georg Brandlb89316f2006-05-17 15:51:16 +00002011- Patch #1180296: Two new functions were added to the locale module:
2012 format_string() to get the effect of "format % items" but locale-aware,
2013 and currency() to format a monetary number with currency sign.
2014
Georg Brandle3a25832006-05-17 14:56:04 +00002015- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2016 and several features added, such as speed and geometry control.
2017
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002018- Patch #1488881: add support for external file objects in bz2 compressed
2019 tarfiles.
2020
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002021- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2022 stdout arguments, making it possible to redirect input and output
2023 for remote debugging.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002071What's New in Python 2.5 alpha 2?
2072=================================
2073
2074*Release date: 27-APR-2006*
2075
2076Core and builtins
2077-----------------
2078
Thomas Heller1b046642006-04-18 18:51:06 +00002079- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2080 by converting these apis from macros into exported functions again:
2081
2082 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2083 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2084 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2085 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2086 PyRun_String Py_CompileString
2087
Martin v. Löwis45294a92006-04-18 06:24:08 +00002088- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2089
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002090- All uses of PyStructSequence_InitType have been changed to initialize
2091 the type objects only once, even if the interpreter is initialized
2092 multiple times.
2093
Neal Norwitz61546162006-04-14 05:20:28 +00002094- Bug #1454485, array.array('u') could crash the interpreter. This was
2095 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2096 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2097
2098- Py_UNICODE is unsigned. It was always documented as unsigned, but
2099 due to a bug had a signed value in previous versions.
2100
Tim Peters3a5e8b12006-04-11 01:44:07 +00002101- Patch #837242: ``id()`` of any Python object always gives a positive
2102 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2103 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002104 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002105 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002106
Tim Peters3a5e8b12006-04-11 01:44:07 +00002107 def __hash__(self):
2108 return id(self) # WRONG
2109
2110 because a hash result must be a (short) Python int but it was always
2111 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002112 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002113 was always usable as a hash value before this patch. That's no longer
2114 necessarily so.
2115
2116- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002117 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002118 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002119 #1454844)
2120
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002121- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2122 involving generators that have paused outside of any ``try`` or ``with``
2123 blocks. (In 2.5a1, a paused generator that was part of a reference
2124 cycle could not be garbage collected, regardless of whether it was
2125 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00002126
Anthony Baxter51bcb682006-04-05 14:51:42 +00002127Extension Modules
2128-----------------
2129
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00002130- Patch #1191065: Fix preprocessor problems on systems where recvfrom
2131 is a macro.
2132
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002133- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2134 fails with an error condition.
2135
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002136- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2137
2138- Bug #1117761: bsddb.*open() no longer raises an exception when using
2139 the cachesize parameter.
2140
2141- Bug #1149413: bsddb.*open() no longer raises an exception when using
2142 a temporary db (file=None) with the 'n' flag to truncate on open.
2143
2144- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2145 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002146
Armin Rigoa9017c32006-04-19 11:50:27 +00002147- Patch #1062014: AF_UNIX sockets under Linux have a special
2148 abstract namespace that is now fully supported.
2149
Anthony Baxter51bcb682006-04-05 14:51:42 +00002150Library
2151-------
2152
Peter Astrand7d1d4362006-07-14 14:04:45 +00002153- Bug #1223937: subprocess.CalledProcessError reports the exit status
2154 of the process using the returncode attribute, instead of
2155 abusing errno.
2156
Tim Peters711bf302006-04-25 03:31:36 +00002157- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2158 a doctest to be skipped (the code is not run, and the expected output
2159 or exception is ignored).
2160
Nick Coghlanda2268f2006-04-24 04:37:15 +00002161- Fixed contextlib.nested to cope with exceptions being raised and
2162 caught inside exit handlers.
2163
Greg Wardab05edc2006-04-23 03:47:58 +00002164- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2165 hex, octal, or binary; add ``append_const`` action; keep going if
2166 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2167 added ``epilog`` for better help generation).
2168
Tim Peters21fbd572006-04-21 21:18:10 +00002169- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2170 called from a thread spawned as a side effect of importing a module.
2171
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002172- The pydoc module now supports documenting packages contained in
2173 .zip or .egg files.
2174
2175- The pkgutil module now has several new utility functions, such
2176 as ``walk_packages()`` to support working with packages that are either
2177 in the filesystem or zip files.
2178
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002179- The mailbox module can now modify and delete messages from
2180 mailboxes, in addition to simply reading them. Thanks to Gregory
2181 K. Johnson for writing the code, and to the 2005 Google Summer of
2182 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002183
Tim Petersc7605f22006-04-17 21:12:33 +00002184- The ``__del__`` method of class ``local`` in module ``_threading_local``
2185 returned before accomplishing any of its intended cleanup.
2186
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002187- Patch #790710: Add breakpoint command lists in pdb.
2188
Martin v. Löwis0db2a982006-04-16 20:55:38 +00002189- Patch #1063914: Add Tkinter.Misc.clipboard_get().
2190
Martin v. Löwis4b501e62006-04-15 08:41:11 +00002191- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
2192
Anthony Baxtere29002c2006-04-12 12:07:31 +00002193- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2194 Windows. Bug #1469163.
2195
Phillip J. Eby47032112006-04-11 01:07:43 +00002196- The warnings, linecache, inspect, traceback, site, and doctest modules
2197 were updated to work correctly with modules imported from zipfiles or
2198 via other PEP 302 __loader__ objects.
2199
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002200- Patch #1467770: Reduce usage of subprocess._active to processes which
2201 the application hasn't waited on.
2202
Martin v. Löwisb04dee92006-04-10 08:34:21 +00002203- Patch #1462222: Fix Tix.Grid.
2204
Neal Norwitza31bf182006-04-09 03:35:43 +00002205- Fix exception when doing glob.glob('anything*/')
2206
Skip Montanaro262fb922006-04-21 02:31:07 +00002207- The pstats.Stats class accepts an optional stream keyword argument to
2208 direct output to an alternate file-like object.
2209
Anthony Baxter51bcb682006-04-05 14:51:42 +00002210Build
2211-----
2212
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002213- The Makefile now has a reindent target, which runs reindent.py on
2214 the library.
2215
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002216- Patch #1470875: Building Python with MS Free Compiler
2217
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002218- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002219
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002220- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2221 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002222 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002223 CXX from --with-cxx-main, see description in README.
2224
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002225- Patch #1429775: Link extension modules with the shared libpython.
2226
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002227- Fixed a libffi build problem on MIPS systems.
2228
Tim Peters8931ff12006-05-13 23:28:20 +00002229- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2230 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2231 and "%zu" for unsigned integers of type ``size_t``.
2232
Anthony Baxter51bcb682006-04-05 14:51:42 +00002233Tests
2234-----
2235
Nick Coghlanda2268f2006-04-24 04:37:15 +00002236- test_contextlib now checks contextlib.nested can cope with exceptions
2237 being raised and caught inside exit handlers.
2238
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002239- test_cmd_line now checks operation of the -m and -c command switches
2240
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002241- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2242 it separately and by hand. It also wasn't cleaning up its changes to
2243 the current Decimal context.
2244
Thomas Woutersabd08882006-04-26 15:53:30 +00002245- regrtest.py now has a -M option to run tests that test the new limits of
2246 containers, on 64-bit architectures. Running these tests is only sensible
2247 on 64-bit machines with more than two gigabytes of memory. The argument
2248 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002256Documentation
2257-------------
2258
Tim Petersb06d28c2006-05-12 01:57:59 +00002259- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2260
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002261- PEP 343: Added Context Types section to the library reference
2262 and attempted to bring other PEP 343 related documentation into
2263 line with the implementation and/or python-dev discussions.
2264
Tim Peters8dc73d22006-04-24 02:03:16 +00002265- Bug #1337990: clarified that ``doctest`` does not support examples
2266 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002269What's New in Python 2.5 alpha 1?
2270=================================
2271
Anthony Baxterebed3f62006-04-03 15:03:44 +00002272*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002273
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002274Core and builtins
2275-----------------
2276
Nick Coghlan43832302006-04-23 17:04:07 +00002277- PEP 338: -m command line switch now delegates to runpy.run_module
2278 allowing it to support modules in packages and zipfiles
2279
Martin v. Löwisc661b882006-04-20 04:54:23 +00002280- On Windows, .DLL is not an accepted file name extension for
2281 extension modules anymore; extensions are only found if they
2282 end in .PYD.
2283
Martin v. Löwisea62d252006-04-03 10:56:49 +00002284- Bug #1421664: sys.stderr.encoding is now set to the same value as
2285 sys.stdout.encoding.
2286
Neal Norwitz92e212f2006-04-03 04:48:37 +00002287- __import__ accepts keyword arguments.
2288
Georg Brandlccadf842006-03-31 18:54:53 +00002289- Patch #1460496: round() now accepts keyword arguments.
2290
Anthony Baxter262c00a2006-03-30 10:53:17 +00002291- Fixed bug #1459029 - unicode reprs were double-escaped.
2292
Hye-Shik Changd478f342006-03-23 12:32:36 +00002293- Patch #1396919: The system scope threads are reenabled on FreeBSD
2294 5.4 and later versions.
2295
Neal Norwitze98ccf62006-03-23 05:39:47 +00002296- Bug #1115379: Compiling a Unicode string with an encoding declaration
2297 now gives a SyntaxError.
2298
Georg Brandlabd1ff82006-03-18 07:59:59 +00002299- Previously, Python code had no easy way to access the contents of a
2300 cell object. Now, a ``cell_contents`` attribute has been added
2301 (closes patch #1170323).
2302
Tim Peterscf79aac2006-03-16 01:14:46 +00002303- Patch #1123430: Python's small-object allocator now returns an arena to
2304 the system ``free()`` when all memory within an arena becomes unused
2305 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2306 freed. Some applications will see a drop in virtual memory size now,
2307 especially long-running applications that, from time to time, temporarily
2308 use a large number of small objects. Note that when Python returns an
2309 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002310 platform C library will in turn return that memory to the operating system.
2311 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002312 appears to be effective at least on Microsoft C and gcc-based systems.
2313 Thanks to Evan Jones for hard work and patience.
2314
Georg Brandl533ff6f2006-03-08 18:09:27 +00002315- Patch #1434038: property() now uses the getter's docstring if there is
2316 no "doc" argument given. This makes it possible to legitimately use
2317 property() as a decorator to produce a read-only property.
2318
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002319- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2320 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2321 of requiring an int or long in slicing and a few other contexts, enabling
2322 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2323
Neal Norwitz995acdf2006-03-07 05:01:00 +00002324- Fixed various bugs reported by Coverity's Prevent tool.
2325
Brett Cannonbf364092006-03-01 04:25:17 +00002326- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2327 new exception base class, BaseException, which has a new message attribute.
2328 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2329 Raising a string exception now raises a DeprecationWarning.
2330
Thomas Woutersfb609f42006-02-28 16:37:25 +00002331- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2332 explicitly relative, using 'from .module import name' to mean 'from the same
2333 package as this module is in. Imports without dots still default to the
2334 old relative-then-absolute, unless 'from __future__ import
2335 absolute_import' is used.
2336
Brett Cannona7446e32006-02-27 23:39:10 +00002337- Properly check if 'warnings' raises an exception (usually when a filter set
2338 to "error" is triggered) when raising a warning for raising string
2339 exceptions.
2340
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002341- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002342 The name was removed from Include/code.h.
2343
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002344- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002345
Guido van Rossum1968ad32006-02-25 22:38:04 +00002346- Patch 1433928:
2347 - The copy module now "copies" function objects (as atomic objects).
2348 - dict.__getitem__ now looks for a __missing__ hook before raising
2349 KeyError.
2350
Tim Peters84ef21c2006-02-28 20:39:06 +00002351- PEP 343: with statement implemented. Needs ``from __future__ import
2352 with_statement``. Use of 'with' as a variable will generate a warning.
2353 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002354 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002355 The following objects have __context__ methods:
2356 - The built-in file type.
2357 - The thread.LockType type.
2358 - The following types defined by the threading module:
2359 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2360 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002361
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002362- Fix the encodings package codec search function to only search
2363 inside its own package. Fixes problem reported in patch #1433198.
2364
2365 Note: Codec packages should implement and register their own
2366 codec search function. PEP 100 has the details.
2367
Tim Peters9ea89d22006-06-04 03:26:02 +00002368- PEP 353: Using ``Py_ssize_t`` as the index type.
2369
2370- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2371 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2372 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2373 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2374 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002375
Neal Norwitzfc76d632006-01-10 06:03:13 +00002376- Patch #1400181, fix unicode string formatting to not use the locale.
2377 This is how string objects work. u'%f' could use , instead of .
2378 for the decimal point. Now both strings and unicode always use periods.
2379
Neal Norwitz671b9e32006-01-09 07:07:12 +00002380- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2381 configure would break checking curses.h.
2382
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002383- Bug #959576: The pwd module is now builtin. This allows Python to be
2384 built on UNIX platforms without $HOME set.
2385
Neal Norwitzc10978f2005-12-19 06:07:16 +00002386- Bug #1072182, fix some potential problems if characters are signed.
2387
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002388- Bug #889500, fix line number on SyntaxWarning for global declarations.
2389
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002390- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2391
Neal Norwitze7214a12005-12-18 05:03:17 +00002392- Support for converting hex strings to floats no longer works.
2393 This was not portable. float('0x3') now raises a ValueError.
2394
Barry Warsaw2a38a862005-12-18 01:27:35 +00002395- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002396 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002397 is now displayed in interactive prompt banner.
2398
Georg Brandlfa166682005-12-17 21:45:17 +00002399- Implementation of PEP 341 - Unification of try/except and try/finally.
2400 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002401 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002402
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002403- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2404 now encodes backslash correctly.
2405
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002406- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2407
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002408- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002409 and long longs.
2410
Neal Norwitz67715f02005-11-09 06:59:35 +00002411- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002412 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002413 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002414
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002415- Replaced most Unicode charmap codecs with new ones using the
2416 new Unicode translate string feature in the builtin charmap
2417 codec; the codecs were created from the mapping tables available
2418 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2419 encodings now include a mapping for the Apple logo)
2420
Tim Peterse3547fd2005-12-16 23:13:57 +00002421- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002422
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002423- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002424
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002425- A new AST parser implementation was completed. The abstract
2426 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002427 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002428
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002429- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002430 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2431
Neal Norwitz708e51a2005-10-03 04:48:15 +00002432- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2433
Neal Norwitz11bd1192005-10-03 00:54:56 +00002434- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2435 Provide a warning when a directory is passed on the command line.
2436
Neal Norwitz40d37812005-10-02 01:48:49 +00002437- Fix segfault with invalid coding.
2438
2439- SF bug #772896: unknown encoding results in MemoryError.
2440
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002441- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002442 supported a __len__() method which evaluated to False when the iterator
2443 was empty.
2444
Guido van Rossum630db602005-09-20 18:49:54 +00002445- On 64-bit platforms, when __len__() returns a value that cannot be
2446 represented as a C int, raise OverflowError.
2447
Skip Montanarof8948ca2005-09-19 03:54:46 +00002448- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002449 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002450
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002451- SF bug #893549: parsing keyword arguments was broken with a few format
2452 codes.
2453
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002454- Changes donated by Elemental Security to make it work on AIX 5.3
2455 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2456 bug #105470: test_pwd fails on 64bit system (Opteron).
2457
Guido van Rossum539c6622005-09-14 17:49:54 +00002458- Changes donated by Elemental Security to make it work on HP-UX 11 on
2459 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2460
Georg Brandl4550b8d2005-08-26 06:43:52 +00002461- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002462 (fixes bug #1119418).
2463
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002464- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2465
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002466- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2467 exceptions that cause a function to exit.
2468
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002469- The implementation of set() and frozenset() was revised to use its
2470 own internal data structure. Memory consumption is reduced by 1/3
2471 and there are modest speed-ups as well. The API is unchanged.
2472
Tim Petersde7990b2005-07-17 23:45:23 +00002473- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2474
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002475- SF bug #1229429: PyObject_CallMethod failed to decrement some
2476 reference counts in some error exit cases.
2477
Tim Petersecc6e6a2005-07-10 22:30:55 +00002478- SF bug #1185883: Python's small-object memory allocator took over
2479 a block managed by the platform C library whenever a realloc specified
2480 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002481 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002482 portable way to copy data from the C-managed block into Python's
2483 small-object space without risking a memory fault. Python's small-object
2484 realloc now leaves such blocks under the control of the platform C
2485 realloc.
2486
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002487- SF bug #1232517: An overflow error was not detected properly when
2488 attempting to convert a large float to an int in os.utime().
2489
Raymond Hettinger3296e692005-06-29 23:29:56 +00002490- SF bug #1224347: hex longs now print with lowercase letters just
2491 like their int counterparts.
2492
Michael W. Hudson188d4362005-06-20 16:52:57 +00002493- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2494 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2495 interpreter states; back out that fix and do a better job (see
2496 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2497 for a longer write-up of the problem).
2498
Michael W. Hudsondf888462005-06-03 14:41:55 +00002499- SF patch #1180995: marshal now uses a binary format by default when
2500 serializing floats.
2501
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002502- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2503 the routines that promise to produce IEEE 754 binary representations
2504 of floats now simply copy bytes around.
2505
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002506- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2507 278.
2508
Brett Cannonc3647ac2005-04-26 03:45:26 +00002509- patch #1109424: int, long, float, complex, and unicode now check for the
2510 proper magic slot for type conversions when subclassed. Previously the
2511 magic slot was ignored during conversion. Semantics now match the way
2512 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002513 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002514 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002515 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002516
Barry Warsawc8d907c2005-04-19 23:43:40 +00002517- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2518 NULL, now raise an AttributeError when attempting to set or delete the
2519 attribute. Previously a TypeError was raised, but this was inconsistent
2520 with the equivalent pure-Python implementation.
2521
Michael W. Hudson774479c2005-04-18 08:46:17 +00002522- It is now safe to call PyGILState_Release() before
2523 PyEval_InitThreads() (note that if there is reason to believe there
2524 are multiple threads around you still must call PyEval_InitThreads()
2525 before using the Python API; this fix is for extension modules that
2526 have no way of knowing if Python is multi-threaded yet).
2527
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002528- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2529 disabled caused a crash.
2530
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002531- Bug #1165306: instancemethod_new allowed the creation of a method
2532 with im_class == im_self == NULL, which caused a crash when called.
2533
Tim Petersecc6e6a2005-07-10 22:30:55 +00002534- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002535 fixes the crash seen in bug #1165761
2536
Raymond Hettinger96229b12005-03-11 06:49:40 +00002537- Added two new builtins, any() and all().
2538
Brett Cannon409d8f22005-03-05 06:47:57 +00002539- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002540 (e.g., ``class C(): pass`` is no longer a syntax error).
2541 Patch #1176012 added support to the 'parser' module and 'compiler' package
2542 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002543
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002544- Patch #1115086: Support PY_LONGLONG in structmember.
2545
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002546- Bug #1155938: new style classes did not check that __init__() was
2547 returning None.
2548
Tim Petersecc6e6a2005-07-10 22:30:55 +00002549- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002550 ('\') with a specific error message.
2551
Martin v. Löwisff232d72005-03-03 09:24:38 +00002552- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2553
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002554- Bug #1124295: the __name__ attribute of file objects was
2555 inadvertently made inaccessible in restricted mode.
2556
Tim Petersecc6e6a2005-07-10 22:30:55 +00002557- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002558 an ferror() call.
2559
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002560- min() and max() now support key= arguments with the same meaning as in
2561 list.sort().
2562
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002563- The peephole optimizer now performs simple constant folding in expressions:
2564 (2+3) --> (5).
2565
Raymond Hettingera422c342005-01-11 03:03:27 +00002566- set and frozenset objects can now be marshalled. SF #1098985.
2567
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002568- Bug #1077106: Poor argument checking could cause memory corruption
2569 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002570
Jeremy Hyltonab630502005-02-04 18:44:06 +00002571- The parser did not complain about future statements in illegal
2572 positions. It once again reports a syntax error if a future
2573 statement occurs after anything other than a doc string.
2574
Neil Schemenauercf52c072005-08-12 17:34:58 +00002575- Change the %s format specifier for str objects so that it returns a
2576 unicode instance if the argument is not an instance of basestring and
2577 calling __str__ on the argument returns a unicode instance.
2578
Tim Petersf4e69282006-02-27 17:15:31 +00002579- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2580 current thread state when the auto-GIL-state machinery knows about
2581 it (since the thread state is being deleted, continuing to remember it
2582 can't help, but can hurt if another thread happens to get created with
2583 the same thread id).

2586-----------------
2587
Georg Brandl43f08a82006-03-31 18:01:16 +00002588- Patch #1380952: fix SSL objects timing out on consecutive read()s
2589
Neal Norwitz05a45592006-03-20 06:30:08 +00002590- Patch #1309579: wait3 and wait4 were added to the posix module.
2591
Anthony Baxterfa869072006-03-20 05:21:58 +00002592- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2593 In addition, the existing ulaw code was updated.
2594
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002595- RFE #567972: Socket objects' family, type and proto properties are

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002775- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2776 been renamed to have only a single underscore prefix. This was done to
2777 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002778
Nick Coghlan43832302006-04-23 17:04:07 +00002779- PEP 338: new module runpy defines a run_module function to support
2780 executing modules which provide access to source code or a code object
2781 via the PEP 302 import mechanisms.
2782
Anthony Baxter93f5b932006-04-03 08:05:07 +00002783- The email module's parsedate_tz function now sets the daylight savings

2791 in attribute values.
2792
Anthony Baxterc51ee692006-04-01 00:57:31 +00002793- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002794 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002795 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002796 module will not be built.
2797
Tim Petersc17976e2006-04-01 00:26:53 +00002798- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2799 aren't officially supported here, and trying to use them will probably
2800 raise an exception some day. But dicts have been allowed, and "mostly
2801 worked", so support for them won't go away without warning.
2802
Georg Brandl338ef7d2006-03-31 18:42:16 +00002803- Bug #1445068: getpass.getpass() can now be given an explicit stream
2804 argument to specify where to write the prompt.
2805

2821
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002822- email 4.0 package now integrated. This is largely the same as the email 3.0
2823 package that was included in Python 2.3, except that PEP 8 module names are
2824 now used (e.g. mail.message instead of email.Message). The MIME classes
2825 have been moved to a subpackage (e.g. email.mime.text instead of
2826 email.MIMEText). The old names are still supported for now. Several
2827 deprecated Message methods have been removed and lots of bugs have been
2828 fixed. More details can be found in the email package documentation.
2829
Walter Dörwald40108c92006-03-27 08:15:44 +00002830- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2831 (a subclass of tuple) that provides incremental decoders and encoders
2832 (a way to use stateful codecs without the stream API). Python functions
2833 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2834 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2835 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002837- Patch #1359365: Calling next() on a closed StringIO.String object raises
2838 a ValueError instead of a StopIteration now (like file and cString.String do).
2839 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2840 called before (like file and StringIO.StringIO do).

2916 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2917 Ronald L. Rivest offered this advice for Python:
2918
2919 "The consensus of researchers in this area (at least as
2920 expressed at the NIST Hash Function Workshop 10/31/05),
2921 is that SHA-256 is a good choice for the time being, but
2922 that research should continue, and other alternatives may
2923 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002924

3105 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003106 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003107 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003108 + Dialect parameter parsing has been re-implemented to improve error

3110 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3111 dictates.
3112 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003113 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003114 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003115 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3116 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003117 + reader now allows \r characters to be quoted (previously it only allowed
3118 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003119 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003120 + Dialect classes passed to the module are no longer instantiated by
3121 the module before being parsed (the former validation scheme required
3122 this, but the mechanism was unreliable).
3123 + The dialect registry now contains instances of the internal
3124 C-coded dialect type, rather than references to python objects.
3125 + the internal c-coded dialect type is now immutable.
3126 + register_dialect now accepts the same keyword dialect specifications
3127 as the reader and writer, allowing the user to register dialects
3128 without first creating a dialect class.
3129 + a configurable limit to the size of parsed fields has been added -
3130 previously, an unmatched quote character could result in the entire
3131 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003132 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003133 the parser field size limit (returning the former limit). The initial
3134 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003135 + A line_num attribute has been added to the reader object, which tracks
3136 the number of lines read from the source iterator. This is not
3137 the same as the number of records returned, as records can span
3138 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003139 + reader and writer objects were not being registered with the cyclic-GC.
3140 This has been fixed.
3141
Brett Cannone6539c42005-01-08 02:43:53 +00003142- _DummyThread objects in the threading module now delete self.__block that is
3143 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3144 lock primitives tend to be limited in number and thus should not be wasted on
3145 a _DummyThread object. Fixes bug #1089632.
3146
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003147- The imghdr module now detects Exif files.
3148
Raymond Hettinger6065d322004-12-20 23:51:53 +00003149- StringIO.truncate() now correctly adjusts the size attribute.
3150 (Bug #951915).
3151
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003152- locale.py now uses an updated locale alias table (built using
3153 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3154 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003155 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003156
Raymond Hettinger3557f422004-12-07 12:02:02 +00003157- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3158
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003159- the pickle module no longer accepts the deprecated None option in the
3160 args tuple returned by __reduce__().
3161
Brett Cannon84667c02004-12-07 03:25:18 +00003162- optparse now optionally imports gettext. This allows its use in setup.py.
3163
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003164- the pickle module no longer uses the deprecated bin parameter.
3165
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003166- the shelve module no longer uses the deprecated binary parameter.
3167
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003168- the pstats module no longer uses the deprecated ignore() method.
3169
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003170- the filecmp module no longer uses the deprecated use_statcache argument.
3171
Raymond Hettinger664347b2004-12-04 21:21:53 +00003172- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3173 extended or overridden by subclasses. Formerly, the subclassed method would
3174 be ignored by the rest of the module. (Bug #1078905).
3175
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003176- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003177 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003178
Walter Dörwald36733692004-12-22 12:50:50 +00003179- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3180 once when a size argument is given. This prevents a buffer overflow in the
3181 tokenizer with very long source lines.
3182
Barry Warsaw538561e2006-01-01 21:48:54 +00003183- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3184 immediately after creating the object, without any intervening
3185 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003186
Skip Montanaro05885812005-01-16 20:48:27 +00003187- The reconvert.quote function can now emit triple-quoted strings. The
3188 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003189
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003190- ``UserString.MutableString`` now supports negative indices in
3191 ``__setitem__`` and ``__delitem__``
3192
Greg Ward40407942005-03-05 02:53:17 +00003193- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3194 correctly.
3195
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003196- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3197 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3198 character even if the user has passed a size parameter to get a proper
3199 line ending. Remove the special handling of a "\r\n" that has been split
3200 between two lines.
3201
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003202- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3203 about illegal code points. The codec now supports PEP 293 style error
3204 handlers.
3205
Walter Dörwald78a78b02005-09-01 12:04:29 +00003206- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003207 from the input stream, so that the output is a byte string in the correct
3208 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003209
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003210- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3211 considering it exactly like a '*'.
3212
Walter Dörwald007f8df2005-10-09 19:42:27 +00003213- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3214 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003215
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003216- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3217
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003218- Patch #1413711: Certain patterns of differences were making difflib
3219 touch the recursion limit.
3220
Walter Dörwald58917a62006-03-31 15:26:22 +00003221- Bug #947906: An object oriented interface has been added to the calendar
3222 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003223 called as a script (e.g. via ``python -mcalendar``). Localized month and
3224 weekday names can be ouput (even if an exotic encoding is used) using
3225 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003226
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003227Build
3228-----
3229
Neal Norwitz602d3392006-03-31 08:21:40 +00003230- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3231 by using -mieee gcc option.
3232
Martin v. Löwis86d66262006-02-17 08:40:11 +00003233- Patch #1432345: Make python compile on DragonFly.
3234
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003235- Build support for Win64-AMD64 was added.
3236
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003237- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3238
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003239- Patch #881820: look for openpty and forkpty also in libbsd.
3240
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003241- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3242 The zlib module is now builtin on Windows.
3243
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003244- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3245
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003246- Bug #1189330: configure did not correctly determine the necessary
3247 value of LINKCC if python was built with GCC 4.0.
3248
Trent Mick8321b422005-07-26 02:29:21 +00003249- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3250 vulnerability in zlib 1.2.1 and 1.2.2.
3251
Brett Cannon08cd5982005-04-24 22:26:38 +00003252- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3253 flags that change binary compatibility. Changes were also made to
3254 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003255 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003256
Bob Ippolitoed233462005-03-29 13:47:59 +00003257- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3258 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3259 no longer exists). This configure patch makes things right.
3260
Martin v. Löwise2713be2005-03-08 15:03:08 +00003261- Bug #1158607: Build with --disable-unicode again.
3262
Brett Cannon46d96232005-02-16 00:07:19 +00003263- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3264 defined. Discovered as a result of not being able to build on OS X.
3265
Brett Cannon516592f2004-12-07 00:42:59 +00003266- setup.py now uses the directories specified in LDFLAGS using the -L option
3267 and in CPPFLAGS using the -I option for adding library and include
3268 directories, respectively, for compiling extension modules against. This has
3269 led to the core being compiled using the values in CPPFLAGS. It also removes
3270 the need for the special-casing of both DarwinPorts and Fink for darwin since
3271 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3272 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3273 Fink, ``-I/opt/local/include`` for DarwinPorts).
3274
Brett Cannon43802422005-02-10 20:48:03 +00003275- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3276 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3277 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3278 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003280C API
3281-----
3282
Tim Petersc9d78aa2006-03-26 23:27:58 +00003283- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3284 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3285 is obtained via the ``PyObject_`` family, it must be released via the
3286 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3287 always been officially true, but when Python's small-object allocator was
3288 introduced, an attempt was made to cater to a few extension modules
3289 discovered at the time that obtained memory via ``PyObject_New`` but
3290 released it via ``PyMem_DEL``. It's years later, and if such code still
3291 exists it will fail now (probably with segfaults, but calling wrong
3292 low-level memory management functions can yield many symptoms).
3293
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003294- Added a C API for set and frozenset objects.
3295
Raymond Hettinger66517482004-12-03 11:45:13 +00003296- Removed PyRange_New().
3297
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003298- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3299 mapping argument now. This string is used as a mapping table. Byte values
3300 greater than the length of the string and 0xFFFE are treated as undefined
3301 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003308
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003309- Patch #1276356: New resource "urlfetch" is implemented. This enables
