Amaury Forgeot d'Arcef633d72008-11-18 22:35:48 +000015- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
16
Benjamin Peterson42fe1a22008-11-17 23:35:24 +000017- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
18
Benjamin Peterson6f08e852008-11-03 15:19:35 +000019- Issue #4048: The parser module now correctly validates relative imports.
20
Amaury Forgeot d'Arc3b335ff2008-10-30 21:40:05 +000021- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
22 method does not return iterators for the 4th and 5th items.
23
Amaury Forgeot d'Arcb50f9922008-09-26 22:46:01 +000024- Issue #3967: Fixed a crash in the count() and find() methods of string-like
25 objects, when the "start" parameter is a huge value.
26
Benjamin Petersond1c7d072008-09-25 20:46:05 +000027- Issue #3936: The parser warnings for using "as" and "with" as variable names
28 didn't fire after import statements.
29
Amaury Forgeot d'Arcafa0d582008-09-01 20:05:08 +000030- Issue #3751: str.rpartition would perform a left-partition when called with
31 a unicode argument.
32
Georg Brandl45c33ce2008-08-11 09:13:26 +000033- Issue #3537: Fix an assertion failure when an empty but presized dict
34 object was stored in the freelist.
35
Neal Norwitz4f3be8a2008-07-31 17:08:14 +000036- Apply security patches from Apple.
37
Neal Norwitz83ac0142008-07-28 05:06:20 +000038- Issue #2620: Overflow checking when allocating or reallocating memory
39 was not always being done properly in some python types and extension
40 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
41 all been updated to perform better checks and places in the code that
42 would previously leak memory on the error path when such an allocation
43 failed have been fixed.
44
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +000045- Issue #2242: Fix a crash when decoding invalid utf-7 input on certain
46 Windows / Visual Studio versions.
47
Mark Dickinsonab396e02008-07-16 11:04:17 +000048- Issue #3360: Fix incorrect parsing of '020000000000.0', which
49 produced a ValueError instead of giving the correct float.
50
Amaury Forgeot d'Arcceda6a62008-07-01 20:52:56 +000051- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
52 set to a custom object whose write() method happens to install
53 another file in sys.stdout.
54
Amaury Forgeot d'Arcb15bdf72008-07-01 20:59:49 +000055- Issue #3088: Corrected a race condition in classes derived from
56 threading.local: the first member set by a thread could be saved in
57 another thread's dictionary.
58
Amaury Forgeot d'Arc3255e132008-06-16 19:22:42 +000059- Issue #3100: Corrected a crash on deallocation of a subclassed weakref which
60 holds the last (strong) reference to its referent.
61
Guido van Rossumaa975432008-04-10 22:43:58 +000062- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
63 having a self-referential tuple, which is possible from C code. Nor did
64 object's tp_str consider that a type's tp_str could do something that could
65 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
66 respectively, fixed the issues. (Backport of r58288 from trunk.)
67
Georg Brandld9f1da02008-03-29 01:50:46 +000068- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
69 cannot be executed.
70
Amaury Forgeot d'Arc8432d862008-03-28 20:45:42 +000071- The compilation of a class nested in another class used to leak one
72 reference on the outer class name.
73
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000074- Issue #1477: With narrow Unicode builds, the unicode escape sequence
75 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
76 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
77 UTF-16 surrogates are generated in this case, like normal unicode literals
78 and the 'unicode-escape' codec.
79
Neal Norwitzb3635f92008-03-18 04:17:36 +000080- Issue #2321: use pymalloc for unicode object string data to reduce
81 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +000082
Sean Reifscheider4af861c2008-03-20 17:39:31 +000083- Issue #2238: Some syntax errors in *args and **kwargs expressions could give
84 bogus error messages.
85
Gregory P. Smith14acde32008-04-09 23:41:13 +000086- Issue #2587: In the C API, PyString_FromStringAndSize() takes a signed size
87 parameter but was not verifying that it was greater than zero. Values
88 less than zero will now raise a SystemError and return NULL to indicate a
89 bug in the calling C code.
90
Gregory P. Smith9aa040d2008-06-02 00:07:25 +000091- Issue #2588, #2589: Fix potential integer underflow and overflow
92 conditions in the PyOS_vsnprintf C API function.
93
Gregory P. Smithcae7f882008-09-07 06:44:12 +000094- Issue #1204: The configure script now tests for additional libraries
95 that may be required when linking against readline. This fixes issues
96 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
Georg Brandld9f1da02008-03-29 01:50:46 +000097
Gregory P. Smitha7a94a02008-09-22 00:22:44 +000098- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
99 library targets in the Makefile.

119 its symbolic link.
120
Thomas Heller275e2292008-08-19 17:17:37 +0000121- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
122 api functions without holding the GIL, which could lead to a fatal
123 error when they failed.
124
Amaury Forgeot d'Arc22679b82008-08-18 19:33:42 +0000125- Issue #2234: distutils failed for some versions of the cygwin compiler. The
126 version reported by these tools does not necessarily follow the python
127 version numbering scheme, so the module is less strict when parsing it.
128
Hirokazu Yamamoto1d63a452008-08-17 09:49:10 +0000129- Issue #2222: Fixed reference leak when occured os.rename()

148 handlers that derive the same default base class.
149
Amaury Forgeot d'Arc198e3532008-03-27 23:41:59 +0000150- Issue #2495: tokenize.untokenize now inserts a space between two consecutive
151 string literals; previously, ["" ""] was rendered as [""""], which is
152 incorrect python code.
153
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +0000154- Issue #2482: Make sure that the coefficient of a Decimal is always
155 stored as a str instance, not as a unicode instance. This ensures

157 regression from Python 2.5.1 to Python 2.5.2.
158
Mark Dickinson26c25d92008-03-25 14:35:25 +0000159- Issue #2478: fix failure of decimal.Decimal(0).sqrt()

173 large messages.
174
Andrew M. Kuchling664553a2008-02-23 19:30:59 +0000175- Bug #1389051, 1092502: fix excessively large memory allocations when
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000176 calling .read() on a socket object wrapped with makefile().
Andrew M. Kuchling664553a2008-02-23 19:30:59 +0000177

Martin v. Löwis897704d2007-06-08 17:29:40 +0000275Core and builtins
276-----------------
277
Martin v. Löwis73c01d42008-02-14 11:26:18 +0000278- Added checks for integer overflows, contributed by Google. Some are
279 only available if asserts are left in the code, in cases where they
280 can't be triggered from Python code.
281
Amaury Forgeot d'Arc3e5f8a62008-02-08 01:05:21 +0000282- Issue #2045: Fix an infinite recursion triggered when printing a subclass of
283 collections.defaultdict, if its default_factory is set to a bound method.
284
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000285- Issue #1920: "while 0" statements were completely removed by the compiler,
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000286 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000287 the condition is false. Now the compiler correctly emits bytecode for the
288 "else" suite.
289
Guido van Rossumd933e0a2008-01-24 18:28:37 +0000290- A few crashers fixed: weakref_in_del.py (issue #1377858);

296 subclassing from both ModuleType and another built-in types.
297
Christian Heimesd2f4cb82008-01-23 14:20:41 +0000298- Bug #1915: Python compiles with --enable-unicode=no again. However
299 several extension methods and modules do not work without unicode
300 support.
301
Mark Dickinson2bebadf2008-01-21 21:54:47 +0000302- Issue #1678380: distinction between 0.0 and -0.0 was lost during constant
303 folding optimization. This was a regression from Python 2.4.
304
Georg Brandl78d50cc2008-01-21 18:36:54 +0000305- Issue #1882: when compiling code from a string, encoding cookies in the

873 be equal to calling getsockname() on the server's socket. Fixed by patch
874 #1545011.
875

Georg Brandld59ea472007-03-08 18:37:35 +0000886- unittest now verifies more of its assumptions. In particular, TestCase
887 and TestSuite subclasses (not instances) are no longer accepted in
888 TestSuite.addTest(). This should cause no incompatibility since it
889 never made sense with ordinary subclasses -- the failure just occurred
890 later, with a more cumbersome exception.

Neal Norwitzff4b63b2006-08-04 04:50:21 +00001242
Anthony Baxterb4096662006-08-16 03:42:26 +00001243*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001244
1245Core and builtins
1246-----------------
1247
Neal Norwitz24b6f202006-09-05 04:43:56 +00001248- Fix infinite recursion when subclassing long and overriding __hash__.
1249
1250- Fix concatenation (+=) of long strings.
1251
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001252- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001253 compared equal or unequal to a string and a UnicodeDecodeError
1254 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001255
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001256 Instead, the equal (==) and unequal (!=) comparison operators will
1257 now issue a UnicodeWarning and interpret the two objects as
1258 unequal. The UnicodeWarning can be filtered as desired using
1259 the warning framework, e.g. silenced completely, turned into an
1260 exception, logged, etc.
1261
1262 Note that compare operators other than equal and unequal will still
1263 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001264
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001265- Fix segfault when doing string formatting on subclasses of long.
1266
1267- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1268 with new-style classes.
1269
1270- Fix bug related to __len__ functions returning negative values with
1271 classic classes.
1272
1273- Patch #1538606, Fix __index__() clipping. There were some problems
1274 discovered with the API and how integers that didn't fit into Py_ssize_t
1275 were handled. This patch attempts to provide enough alternatives
1276 to effectively use __index__.
1277
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001278- Bug #1536021: __hash__ may now return long int; the final hash
1279 value is obtained by invoking hash on the long int.
1280
Thomas Hellerab1049c2006-08-08 17:37:00 +00001281- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1282
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001283- Bug #1535165: fixed a segfault in input() and raw_input() when
1284 sys.stdin is closed.
1285
Thomas Heller74d36f02006-08-04 18:17:40 +00001286- On Windows, the PyErr_Warn function is now exported from
1287 the Python dll again.
1288
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001289- Bug #1191458: tracing over for loops now produces a line event
1290 on each iteration. Fixing this problem required changing the .pyc
1291 magic number. This means that .pyc files generated before 2.5c1
1292 will be regenerated.
1293
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001294- Bug #1333982: string/number constants were inappropriately stored
1295 in the byte code and co_consts even if they were not used, ie
1296 immediately popped off the stack.
1297
Georg Brandle9462c72006-08-04 18:03:37 +00001298- Fixed a reference-counting problem in property().

1301Library
1302-------
1303
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001304- Fix a bug in the ``compiler`` package that caused invalid code to be
1305 generated for generator expressions.
1306
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001307- The distutils version has been changed to 2.5.0. The change to
1308 keep it programmatically in sync with the Python version running
1309 the code (introduced in 2.5b3) has been reverted. It will continue
1310 to be maintained manually as static string literal.
1311
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001312- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001313 and this cannot be converted to the required C type, an exception is
1314 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001315 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001316
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001317- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001318 an exception.
1319
Tim Peterscbdd3502006-09-05 01:47:53 +00001320- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001321 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001322 workarounds for clocks with low resolution, to stop the code yielding
1323 duplicate UUIDs.
1324
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001325- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1326 before raising SystemExit, allowing IDLE to honor quit() and exit().
1327
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001328- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1329
Georg Brandl7a1af772006-08-14 21:55:28 +00001330- Patch #1536071: trace.py should now find the full module name of a
1331 file correctly even on Windows.
1332
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001333- logging's atexit hook now runs even if the rest of the module has
1334 already been cleaned up.
1335
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001336- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001337
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001338- Bug #1531405, format_exception no longer raises an exception if
1339 str(exception) raised an exception.
1340
Neil Schemenauer06ded092006-08-04 16:20:30 +00001341- Fix a bug in the ``compiler`` package that caused invalid code to be
1342 generated for nested functions.

Georg Brandl3335a7a2006-08-14 21:42:55 +00001352- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1353 raises the correct exceptions.
1354
Thomas Heller1ce433e2006-08-14 16:20:04 +00001355- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1356 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1357
Thomas Heller86720042006-08-14 11:17:48 +00001358- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1359 uses the _as_parameter_ attribute when objects are passed to foreign
1360 function calls. The ctypes version number was changed to 1.0.1.
1361
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001362- Bug #1530559, struct.pack raises TypeError where it used to convert.
1363 Passing float arguments to struct.pack when integers are expected
1364 now triggers a DeprecationWarning.
1365
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001366

Neal Norwitza1f10902006-07-12 07:28:29 +00001413
1414Core and builtins
1415-----------------
1416
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001417- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001418 returned a long (see PEP 353).
1419
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001420- Bug #1515471: string.replace() accepts character buffers again.
1421
Neal Norwitz07aadb12006-07-30 06:55:48 +00001422- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1423 This provides the proper warning for struct.pack().
1424 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1425
Neal Norwitz0d62a062006-07-30 06:53:31 +00001426- Patch #1531113: Fix augmented assignment with yield expressions.
1427 Also fix a SystemError when trying to assign to yield expressions.
1428
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001429- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1430 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1431 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1432 excessive filesystem operations during imports.
1433
Tim Petersbc24eee2006-07-27 01:14:53 +00001434- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1435 operations on signed longs that are formally undefined by C.
1436 Unfortunately, at least one compiler now cares about that, so complicated
1437 the code to make that compiler happy again.
1438
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001439- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1440
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001441- Patch #1232023: Stop including current directory in search
1442 path on Windows.
1443
Neal Norwitze1fdb322006-07-21 05:32:28 +00001444- Fix some potential crashes found with failmalloc.
1445
Neal Norwitze7563102006-07-17 01:00:16 +00001446- Fix warnings reported by Klocwork's static analysis tool.
1447
Neal Norwitz84be93b2006-07-16 01:50:38 +00001448- Bug #1512814, Fix incorrect lineno's when code within a function
1449 had more than 255 blank lines.
1450
Georg Brandl9dceedb2006-07-12 15:31:17 +00001451- Patch #1521179: Python now accepts the standard options ``--help`` and
1452 ``--version`` as well as ``/?`` on Windows.
1453
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001454- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001455 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001456 This means that .pyc files generated before 2.5b3 will be regenerated.

Tim Peters112aad32006-07-19 00:03:19 +00001458- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001459 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001460 new ``sys._current_frames()`` returns a dictionary with one entry,
1461 mapping the faux "thread id" 0 to the current frame.

1467-------
1468
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001469- Correction of patch #1455898: In the mbcs decoder, set final=False
1470 for stream decoder, but final=True for the decode function.
1471
Georg Brandl07fec3a2006-08-01 18:49:24 +00001472- os.urandom no longer masks unrelated exceptions like SystemExit or
1473 KeyboardInterrupt.
1474
Tim Peters4643c2f2006-08-10 22:45:34 +00001475- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001476 shutil.copytree on Windows
1477
Georg Brandle34ac7c2006-07-30 11:07:23 +00001478- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1479 refers to file descriptors, not file objects.
1480
Tim Peterscbdd3502006-09-05 01:47:53 +00001481- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001482 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001483 #1513611, and probably others.
1484
Georg Brandledd9b0d2006-07-29 09:33:26 +00001485- Bug #1441397: The compiler module now recognizes module and function
1486 docstrings correctly as it did in Python 2.4.
1487
Tim Peters6f681472006-07-27 23:44:37 +00001488- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1489 lost that tests are sorted by name before being run. This rarely
1490 matters for well-written tests, but can create baffling symptoms if
1491 side effects from one test to the next affect outcomes. ``DocTestFinder``
1492 has been changed to sort the list of tests it returns.
1493
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001494- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001495 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001496
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001497- Bug #978833: Really close underlying socket in _socketobject.close.
1498
Georg Brandldb232dc2006-08-20 13:15:43 +00001499- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1500 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001501
Georg Brandlcf0c1722006-07-26 07:23:32 +00001502- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1503 to recursive calls and call it with the failing package name.
1504
Martin v. Löwis0b483032006-07-25 09:53:12 +00001505- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1506
Georg Brandlc13c34c2006-07-24 14:09:56 +00001507- Patch #1515343: Fix printing of deprecated string exceptions with a
1508 value in the traceback module.
1509
Greg Ward48fae7a2006-07-23 16:05:51 +00001510- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1511
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001512- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1513
Brett Cannoncaebe222006-07-18 04:41:36 +00001514- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1515 argument tuple. For arguments where zero is illegal, the value is forced to
1516 the minimum value that is correct. This is to support an undocumented but
1517 common way people used to fill in inconsequential information in the time
1518 tuple pre-2.4.
1519
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001520- Patch #1220874: Update the binhex module for Mach-O.
1521
Barry Warsawb110bad2006-07-21 14:51:07 +00001522- The email package has improved RFC 2231 support, specifically for
1523 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1524 (name*0=<blah>) parameter continuations. This may change the types of
1525 values returned from email.message.Message.get_param() and friends.
1526 Specifically in some cases where non-encoded continuations were used,
1527 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1528 will just return the string (since non-encoded continuations don't have
1529 charset and language parts).
1530
1531 Also, whereas % values were decoded in all parameter continuations, they are
1532 now only decoded in encoded parameter parts.
1533
Ronald Oussoren3075e162006-07-25 20:28:55 +00001534- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1535
1536- Bug #1517996: IDLE now longer shows the default Tk menu when a
1537 path browser, class browser or debugger is the frontmost window on MacOS X
1538
Barry Warsaw00decd72006-07-27 23:43:15 +00001539- Patch #1520294: Support for getset and member descriptors in types.py,
1540 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1541 of an object against these built-in types and more importantly, for getting
1542 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001545Extension Modules
1546-----------------
1547
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001548- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1549 a socket operation on a socket with a timeout, the exception will be
1550 caught correctly. Previously, the exception was not caught.
1551
Thomas Heller1393d6a2006-07-28 21:43:20 +00001552- Patch #1529514: The _ctypes extension is now compiled on more
1553 openbsd target platforms.
1554
Tim Peters9cab5932006-07-28 00:30:00 +00001555- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1556 a memory leak, affecting pickles and deep copies.
1557
Tim Petersbc24eee2006-07-27 01:14:53 +00001558- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001559 Paul Eggert.
1560
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001561- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1562
Thomas Hellerce049a02006-07-14 17:51:14 +00001563- Patch #1521817: Index range checking on ctypes arrays containing
1564 exactly one element enabled again. This allows iterating over these
1565 arrays, without the need to check the array size before.
1566
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001567- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001568 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001569 /dev/null in certain cases; this is now fixed.
1570
Thomas Heller47d7a062006-07-12 08:43:47 +00001571- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1572 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001573
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001574- Because of a misspelled preprocessor symbol, ctypes was always
1575 compiled without thread support; this is now fixed.
1576
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001577- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1578 methods now allow their database parameter to be None as the
1579 sleepycat API allows.
1580
Matt Flemingec926502006-07-28 11:27:27 +00001581- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1582 bluetooth API compared with Linux and FreeBSD.
1583
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001584Tests
1585-----
1586
1587- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1588 how long the test file should take to play. Now accepts taking 2.93 secs
1589 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1590
Georg Brandl4793aa32006-07-28 18:31:39 +00001591- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1592 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1593 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001600Mac
1601---
1602
1603- PythonLauncher now works correctly when the path to the script contains
1604 characters that are treated specially by the shell (such as quotes).
1605
1606- Bug #1527397: PythonLauncher now launches scripts with the working directory
1607 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001608 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001609 expect.

1618-----------------
1619
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001620- Bug #1441486: The literal representation of -(sys.maxint - 1)
1621 again evaluates to a int object, not a long.
1622
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001623- Bug #1501934: The scope of global variables that are locally assigned
1624 using augmented assignment is now correctly determined.
1625
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001626- Bug #927248: Recursive method-wrapper objects can now safely
1627 be released.
1628
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001629- Bug #1417699: Reject locale-specific decimal point in float()
1630 and atof().
1631
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001632- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1633 omit a default "error" argument for NULL pointer. This allows
1634 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001635
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001636- Bug #1519018: 'as' is now validated properly in import statements.
1637
Neal Norwitz28746ab2006-07-09 22:14:42 +00001638- On 64 bit systems, int literals that use less than 64 bits are
1639 now ints rather than longs.
1640
Neal Norwitzed657552006-07-10 00:04:44 +00001641- Bug #1512814, Fix incorrect lineno's when code at module scope
1642 started after line 256.
1643
Tim Peters32a83612006-07-10 21:08:24 +00001644- New function ``sys._current_frames()`` returns a dict mapping thread
1645 id to topmost thread stack frame. This is for expert use, and is
1646 especially useful for debugging application deadlocks. The functionality
1647 was previously available in Fazal Majid's ``threadframe`` extension
1648 module, but it wasn't possible to do this in a wholly threadsafe way from
1649 an extension.

1655 VS 2003.
1656
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001657- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1658
Tim Peters32a83612006-07-10 21:08:24 +00001659- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001660 environment variable to be set in order to the SDK environment
1661 for finding the compiler, include files, etc.

1666
Thomas Woutersadd19112006-07-05 11:03:49 +00001667- string.Template() now correctly handles tuple-values. Previously,
1668 multi-value tuples would raise an exception and single-value tuples would
1669 be treated as the value they contain, instead.
1670
Martin v. Löwisede77f52006-07-03 13:01:35 +00001671- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1673
Martin v. Löwis45482392006-07-03 12:28:58 +00001674- Bug #1267547: Put proper recursive setup.py call into the
1675 spec file generated by bdist_rpm.
1676
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001677- Bug #1514693: Update turtle's heading when switching between
1678 degrees and radians.
1679
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001680- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001681 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001682
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001683- Bug #1514703: Only setup canvas window in turtle when the canvas
1684 is created.
1685
Martin v. Löwis7596e832006-07-01 15:33:37 +00001686- Bug #1513223: .close() of a _socketobj now releases the underlying
1687 socket again, which then gets closed as it becomes unreferenced.
1688
Fred Drake10497c82006-06-29 02:57:48 +00001689- Bug #1504333: Make sgmllib support angle brackets in quoted
1690 attribute values.
1691
1692- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1693 sgmllib ('[' and ']' were not accepted).
1694
Georg Brandl1be63af2006-06-28 20:23:25 +00001695- Fix a bug in the turtle module's end_fill function.
1696
Brett Cannon53ab5b72006-06-22 16:49:14 +00001697- Bug #1510580: The 'warnings' module improperly required that a Warning
1698 category be either a types.ClassType and a subclass of Warning. The proper
1699 check is just that it is a subclass with Warning as the documentation states.
1700
Georg Brandlad29e632006-06-21 17:45:17 +00001701- The compiler module now correctly compiles the new try-except-finally
1702 statement (bug #1509132).
1703
Neal Norwitz60373cd2006-06-22 06:30:50 +00001704- The wsgiref package is now installed properly on Unix.
1705
Vinay Sajip28e57612006-07-01 10:45:20 +00001706- A bug was fixed in logging.config.fileConfig() which caused a crash on
1707 shutdown when fileConfig() was called multiple times.
1708
Gerhard Häring762fbd32006-07-02 17:48:30 +00001709- The sqlite3 module did cut off data from the SQLite database at the first
1710 null character before sending it to a custom converter. This has been fixed
1711 now.

1714-----------------
1715
Tim Peters112aad32006-07-19 00:03:19 +00001716- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1717 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1718 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001719
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001720- Assigning None to pointer type fields in ctypes structures possible
1721 overwrote the wrong fields, this is fixed now.
1722
1723- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1724 on non-Windows platforms.
1725
1726- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1727 integer or long, without range checking.
1728
1729- Patch #1517790: It is now possible to use custom objects in the ctypes
1730 foreign function argtypes sequence as long as they provide a from_param
1731 method, no longer is it required that the object is a ctypes type.
1732
1733- The '_ctypes' extension module now works when Python is configured
1734 with the --without-threads option.
1735
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001736- Bug #1513646: os.access on Windows now correctly determines write
1737 access, again.
1738
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001739- Bug #1512695: cPickle.loads could crash if it was interrupted with
1740 a KeyboardInterrupt.
1741
Neal Norwitza12aa882006-07-06 06:45:08 +00001742- Bug #1296433: parsing XML with a non-default encoding and

Martin v. Löwisd73168d2006-07-14 09:58:55 +00001750- Automate Windows build process for the Win64 SSL module.
1751
Tim Peters32a83612006-07-10 21:08:24 +00001752- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001753 Previously, the slight difference could cause compilation errors of the
1754 'zlib' module on systems with more than one version of zlib.
1755
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001756- The MSI compileall step was fixed to also support a TARGETDIR

1775 documentation for the warnings module.
1776
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001777- Patch #1509163: MS Toolkit Compiler no longer available.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001784
Anthony Baxterd1136802006-06-19 12:04:15 +00001785*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001786
1787Core and builtins
1788-----------------
1789
Georg Brandla56b9152006-06-19 06:35:54 +00001790- Patch #1507676: Error messages returned by invalid abstract object operations
1791 (such as iterating over an integer) have been improved and now include the
1792 type of the offending object to help with debugging.
1793
Brett Cannonea3912b2006-06-13 21:46:41 +00001794- Bug #992017: A classic class that defined a __coerce__() method that returned
1795 its arguments swapped would infinitely recurse and segfault the interpreter.
1796
Neal Norwitz909eb122006-06-12 02:13:21 +00001797- Fix the socket tests so they can be run concurrently.
1798
Neal Norwitzb9845e72006-06-12 02:11:18 +00001799- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001800 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001801
Brett Cannon22565aa2006-06-09 22:31:23 +00001802- Bug #532646: object.__call__() will continue looking for the __call__
1803 attribute on objects until one without one is found. This leads to recursion
1804 when you take a class and set its __call__ attribute to an instance of the
1805 class. Originally fixed for classic classes, but this fix is for new-style.
1806 Removes the infinite_rec_3 crasher.
1807
Georg Brandl24250812006-06-09 18:45:48 +00001808- The string and unicode methods startswith() and endswith() now accept
1809 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1810
Brett Cannonde3b0522006-06-08 17:00:45 +00001811- Buffer objects, at the C level, never used the char buffer
1812 implementation even when the char buffer for the wrapped object was
1813 explicitly requested (originally returned the read or write buffer).
1814 Now a TypeError is raised if the char buffer is not present but is
1815 requested.
1816
Georg Brandlddbaa662006-06-04 21:56:52 +00001817- Patch #1346214: Statements like "if 0: suite" are now again optimized
1818 away like they were in Python 2.4.
1819
Georg Brandlb7c8f542006-05-27 12:30:25 +00001820- Builtin exceptions are now full-blown new-style classes instead of
1821 instances pretending to be classes, which speeds up exception handling
1822 by about 80% in comparison to 2.5a2.
1823
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001824- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1825 Unicode 4.1.
1826
Georg Brandlf4ef1162006-05-26 18:03:31 +00001827- Patch #921466: sys.path_importer_cache is now used to cache valid and
1828 invalid file paths for the built-in import machinery which leads to
1829 fewer open calls on startup.
1830
Tim Peters696cf432006-05-24 21:10:40 +00001831- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1832 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1833 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1834 the number of input digits (it was and remains linear-time for bases
1835 2, 4, 8, 16 and 32).
1836
Tim Petersb713ec22006-05-23 18:45:30 +00001837- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1838 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1839 an integer close to ``sys.maxint``. This was repaired by patch
1840 #1335972, which also gives a nice speedup.
1841
Richard Jonescebbefc2006-05-23 18:28:17 +00001842- Patch #1337051: reduced size of frame objects.
1843
1844- PyErr_NewException now accepts a tuple of base classes as its
1845 "base" parameter.
1846
Richard Jones7c88dcc2006-05-23 10:37:38 +00001847- Patch #876206: function call speedup by retaining allocated frame
1848 objects.
1849
Georg Brandl7b90e162006-05-18 07:01:27 +00001850- Bug #1462152: file() now checks more thoroughly for invalid mode
1851 strings and removes a possible "U" before passing the mode to the
1852 C library function.
1853
Neal Norwitz1004a532006-05-15 07:17:23 +00001854- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1855
Neal Norwitz373f0a72006-05-15 07:04:36 +00001856- Bug #1487966: Fix SystemError with conditional expression in assignment
1857
Martin v. Löwis879768d2006-05-11 13:28:43 +00001858- WindowsError now has two error code attributes: errno, which carries
1859 the error values from errno.h, and winerror, which carries the error
1860 values from winerror.h. Previous versions put the winerror.h values
1861 (from GetLastError()) into the errno attribute.
1862
Martin v. Löwis77736712006-05-04 05:51:03 +00001863- Patch #1475845: Raise IndentationError for unexpected indent.
1864
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001865- Patch #1479181: split open() and file() from being aliases for each other.
1866
Tim Peters44bd9862006-06-01 13:49:23 +00001867- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1868 methods were always silently ignored by dictionaries when comparing keys.
1869 They are now passed through (except when using the C API function
1870 ``PyDict_GetItem()``, whose semantics did not change).
1871
1872- Bug #1456209: In some obscure cases it was possible for a class with a
1873 custom ``__eq__()`` method to confuse dict internals when class instances
1874 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1875 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001877Extension Modules
1878-----------------
1879
Trent Mick960a3f82006-06-28 20:30:41 +00001880- Bug #1295808: expat symbols should be namespaced in pyexpat
1881
1882- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1883
Brett Cannon6ee7d012006-06-08 16:23:04 +00001884- Change binascii.hexlify to accept a read-only buffer instead of only a char
1885 buffer and actually follow its documentation.
1886
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001887- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1888
Nick Coghlanc649ec52006-05-29 12:43:05 +00001889- Patch #1478788 (modified version): The functional extension module has
1890 been renamed to _functools and a functools Python wrapper module added.
1891 This provides a home for additional function related utilities that are
1892 not specifically about functional programming. See PEP 309.
1893
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001894- Patch #1493701: performance enhancements for struct module.
1895
Georg Brandl378d5922006-05-17 14:26:50 +00001896- Patch #1490224: time.altzone is now set correctly on Cygwin.
1897
Georg Brandl8d3342b2006-05-16 07:38:27 +00001898- Patch #1435422: zlib's compress and decompress objects now have a
1899 copy() method.
1900
Andrew MacIntyre92913322006-06-13 15:04:24 +00001901- Patch #1454481: thread stack size is now tunable at runtime for thread
1902 enabled builds on Windows and systems with Posix threads support.
1903
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001904- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1905 (up to the system limit of 32K characters).
1906
1907- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1908 As a result, these functions now raise WindowsError instead of OSError.
1909
Tim Peters7a822da2006-05-25 21:50:17 +00001910- ``time.clock()`` on Win64 should use the high-performance Windows
1911 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1912 Windows platforms).
1913
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001914- Calling Tk_Init twice is refused if the first call failed as that
1915 may deadlock.
1916
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001917- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1918 accept it without potentially using an uninitialized pointer.
1919
1920- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1921 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1922 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001923
Gregory P. Smith372b5832006-06-05 18:48:21 +00001924- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001925 [pybsddb project SF patch number 1466734]
1926
Gregory P. Smith372b5832006-06-05 18:48:21 +00001927- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1928 parameter is supplied. [SF pybsddb bug #1477863]
1929
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001930- bsddb: the __len__ method of a DB object has been fixed to return correct
1931 results. It could previously incorrectly return 0 in some cases.
1932 Fixes SF bug 1493322 (pybsddb bug 1184012).
1933
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001934- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1935 aborts the db transaction safely when a modifier callback fails.
1936 Fixes SF python patch/bug #1408584.
1937
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001938- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001939 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001940 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1941 database calls that would previously deadlock. [SF python bug #775414]
1942
Vinay Sajip28e57612006-07-01 10:45:20 +00001943- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001944
Walter Dörwald4994d952006-06-19 08:07:50 +00001945- Patch #1506645: add Python wrappers for the curses functions
1946 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001947

1949-------
1950
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001951- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1952 functions.
1953
Martin v. Löwis3798da02006-06-17 18:44:27 +00001954- Patch #812986: Update turtle output even if not tracing.
1955
Vinay Sajip28e57612006-07-01 10:45:20 +00001956- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001957 Tkinter.BaseWidget.
1958
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001959- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1960
Martin v. Löwis337487e2006-06-17 09:15:14 +00001961- Patch #763580: Add name and value arguments to Tkinter variable
1962 classes.
1963
Georg Brandl83cc0d02006-06-14 08:50:03 +00001964- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1965 mime.types file for determining MIME types.
1966
Georg Brandl2605ca82006-06-14 06:08:31 +00001967- Bug #1339007: Shelf objects now don't raise an exception in their
1968 __del__ method when initialization failed.
1969
Martin v. Löwisd8251432006-06-14 05:21:04 +00001970- Patch #1455898: The MBCS codec now supports the incremental mode for
1971 double-byte encodings.
1972
Tim Peters43898b42006-06-14 04:09:25 +00001973- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1974 guarantee that adjacent triples in the return list always describe
1975 non-adjacent blocks. Previously, a pair of matching blocks could end
1976 up being described by multiple adjacent triples that formed a partition
1977 of the matching pair.
1978
Greg Ward0e0c9f42006-06-11 16:24:11 +00001979- Bug #1498146: fix optparse to handle Unicode strings in option help,
1980 description, and epilog.
1981
Greg Wardd1c797e2006-06-11 14:42:41 +00001982- Bug #1366250: minor optparse documentation error.
1983
Greg Ward7f547402006-06-11 00:40:49 +00001984- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1985 clarify docs.
1986
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001987- The wsgiref package has been added to the standard library.
1988
Nick Coghlan676725d2006-06-08 13:54:49 +00001989- The functions update_wrapper() and wraps() have been added to the functools
1990 module. These make it easier to copy relevant metadata from the original
1991 function when writing wrapper functions.
1992
Tim Petersd6a9eef2006-06-05 01:48:21 +00001993- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1994 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001995
Martin v. Löwis3f767792006-06-04 19:36:28 +00001996- Patch #1359618: Speed up charmap encoder by using a trie structure
1997 for lookup.
1998
Tim Petersd609b1a2006-06-02 23:22:51 +00001999- The functions in the ``pprint`` module now sort dictionaries by key
2000 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2001 if and only if its display required more than one line, although that
2002 wasn't documented. The new behavior increases predictability; e.g.,
2003 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2004
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002005- Patch #1497027: try HTTP digest auth before basic auth in urllib2
2006 (thanks for J. J. Lee).
2007
Georg Brandl2b330372006-05-28 20:23:12 +00002008- Patch #1496206: improve urllib2 handling of passwords with respect to
2009 default HTTP and HTTPS ports.
2010
George Yoshidaf3c65de2006-05-28 16:39:09 +00002011- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
2012
Bob Ippolito7298f272006-05-23 18:43:47 +00002013- Patch #1281707: speed up gzip.readline.
2014
Georg Brandlb89316f2006-05-17 15:51:16 +00002015- Patch #1180296: Two new functions were added to the locale module:
2016 format_string() to get the effect of "format % items" but locale-aware,
2017 and currency() to format a monetary number with currency sign.
2018
Georg Brandle3a25832006-05-17 14:56:04 +00002019- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2020 and several features added, such as speed and geometry control.
2021
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002022- Patch #1488881: add support for external file objects in bz2 compressed
2023 tarfiles.
2024
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002025- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2026 stdout arguments, making it possible to redirect input and output
2027 for remote debugging.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002075What's New in Python 2.5 alpha 2?
2076=================================
2077
2078*Release date: 27-APR-2006*
2079
2080Core and builtins
2081-----------------
2082
Thomas Heller1b046642006-04-18 18:51:06 +00002083- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2084 by converting these apis from macros into exported functions again:
2085
2086 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2087 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2088 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2089 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2090 PyRun_String Py_CompileString
2091
Martin v. Löwis45294a92006-04-18 06:24:08 +00002092- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2093
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002094- All uses of PyStructSequence_InitType have been changed to initialize
2095 the type objects only once, even if the interpreter is initialized
2096 multiple times.
2097
Neal Norwitz61546162006-04-14 05:20:28 +00002098- Bug #1454485, array.array('u') could crash the interpreter. This was
2099 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2100 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2101
2102- Py_UNICODE is unsigned. It was always documented as unsigned, but
2103 due to a bug had a signed value in previous versions.
2104
Tim Peters3a5e8b12006-04-11 01:44:07 +00002105- Patch #837242: ``id()`` of any Python object always gives a positive
2106 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2107 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002108 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002109 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002110
Tim Peters3a5e8b12006-04-11 01:44:07 +00002111 def __hash__(self):
2112 return id(self) # WRONG
2113
2114 because a hash result must be a (short) Python int but it was always
2115 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002116 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002117 was always usable as a hash value before this patch. That's no longer
2118 necessarily so.
2119
2120- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002121 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002122 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002123 #1454844)
2124
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002125- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2126 involving generators that have paused outside of any ``try`` or ``with``
2127 blocks. (In 2.5a1, a paused generator that was part of a reference
2128 cycle could not be garbage collected, regardless of whether it was
2129 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00002130
Anthony Baxter51bcb682006-04-05 14:51:42 +00002131Extension Modules
2132-----------------
2133
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00002134- Patch #1191065: Fix preprocessor problems on systems where recvfrom
2135 is a macro.
2136
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002137- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2138 fails with an error condition.
2139
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002140- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2141
2142- Bug #1117761: bsddb.*open() no longer raises an exception when using
2143 the cachesize parameter.
2144
2145- Bug #1149413: bsddb.*open() no longer raises an exception when using
2146 a temporary db (file=None) with the 'n' flag to truncate on open.
2147
2148- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2149 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002150
Armin Rigoa9017c32006-04-19 11:50:27 +00002151- Patch #1062014: AF_UNIX sockets under Linux have a special
2152 abstract namespace that is now fully supported.
2153
Anthony Baxter51bcb682006-04-05 14:51:42 +00002154Library
2155-------
2156
Peter Astrand7d1d4362006-07-14 14:04:45 +00002157- Bug #1223937: subprocess.CalledProcessError reports the exit status
2158 of the process using the returncode attribute, instead of
2159 abusing errno.
2160
Tim Peters711bf302006-04-25 03:31:36 +00002161- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2162 a doctest to be skipped (the code is not run, and the expected output
2163 or exception is ignored).
2164
Nick Coghlanda2268f2006-04-24 04:37:15 +00002165- Fixed contextlib.nested to cope with exceptions being raised and
2166 caught inside exit handlers.
2167
Greg Wardab05edc2006-04-23 03:47:58 +00002168- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2169 hex, octal, or binary; add ``append_const`` action; keep going if
2170 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2171 added ``epilog`` for better help generation).
2172
Tim Peters21fbd572006-04-21 21:18:10 +00002173- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2174 called from a thread spawned as a side effect of importing a module.
2175
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002176- The pydoc module now supports documenting packages contained in
2177 .zip or .egg files.
2178
2179- The pkgutil module now has several new utility functions, such
2180 as ``walk_packages()`` to support working with packages that are either
2181 in the filesystem or zip files.
2182
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002183- The mailbox module can now modify and delete messages from
2184 mailboxes, in addition to simply reading them. Thanks to Gregory
2185 K. Johnson for writing the code, and to the 2005 Google Summer of
2186 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002187
Tim Petersc7605f22006-04-17 21:12:33 +00002188- The ``__del__`` method of class ``local`` in module ``_threading_local``
2189 returned before accomplishing any of its intended cleanup.
2190
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002191- Patch #790710: Add breakpoint command lists in pdb.
2192
Martin v. Löwis0db2a982006-04-16 20:55:38 +00002193- Patch #1063914: Add Tkinter.Misc.clipboard_get().
2194
Martin v. Löwis4b501e62006-04-15 08:41:11 +00002195- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
2196
Anthony Baxtere29002c2006-04-12 12:07:31 +00002197- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2198 Windows. Bug #1469163.
2199
Phillip J. Eby47032112006-04-11 01:07:43 +00002200- The warnings, linecache, inspect, traceback, site, and doctest modules
2201 were updated to work correctly with modules imported from zipfiles or
2202 via other PEP 302 __loader__ objects.
2203
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002204- Patch #1467770: Reduce usage of subprocess._active to processes which
2205 the application hasn't waited on.
2206
Martin v. Löwisb04dee92006-04-10 08:34:21 +00002207- Patch #1462222: Fix Tix.Grid.
2208
Neal Norwitza31bf182006-04-09 03:35:43 +00002209- Fix exception when doing glob.glob('anything*/')
2210
Skip Montanaro262fb922006-04-21 02:31:07 +00002211- The pstats.Stats class accepts an optional stream keyword argument to
2212 direct output to an alternate file-like object.
2213
Anthony Baxter51bcb682006-04-05 14:51:42 +00002214Build
2215-----
2216
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002217- The Makefile now has a reindent target, which runs reindent.py on
2218 the library.
2219
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002220- Patch #1470875: Building Python with MS Free Compiler
2221
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002222- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002223
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002224- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2225 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002226 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002227 CXX from --with-cxx-main, see description in README.
2228
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002229- Patch #1429775: Link extension modules with the shared libpython.
2230
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002231- Fixed a libffi build problem on MIPS systems.
2232
Tim Peters8931ff12006-05-13 23:28:20 +00002233- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2234 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2235 and "%zu" for unsigned integers of type ``size_t``.
2236
Anthony Baxter51bcb682006-04-05 14:51:42 +00002237Tests
2238-----
2239
Nick Coghlanda2268f2006-04-24 04:37:15 +00002240- test_contextlib now checks contextlib.nested can cope with exceptions
2241 being raised and caught inside exit handlers.
2242
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002243- test_cmd_line now checks operation of the -m and -c command switches
2244
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002245- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2246 it separately and by hand. It also wasn't cleaning up its changes to
2247 the current Decimal context.
2248
Thomas Woutersabd08882006-04-26 15:53:30 +00002249- regrtest.py now has a -M option to run tests that test the new limits of
2250 containers, on 64-bit architectures. Running these tests is only sensible
2251 on 64-bit machines with more than two gigabytes of memory. The argument
2252 passed is the maximum amount of memory for the tests to use.

2261-------------
2262
Tim Petersb06d28c2006-05-12 01:57:59 +00002263- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2264
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002265- PEP 343: Added Context Types section to the library reference
2266 and attempted to bring other PEP 343 related documentation into
2267 line with the implementation and/or python-dev discussions.
2268
Tim Peters8dc73d22006-04-24 02:03:16 +00002269- Bug #1337990: clarified that ``doctest`` does not support examples
2270 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002273What's New in Python 2.5 alpha 1?
2274=================================
2275
Anthony Baxterebed3f62006-04-03 15:03:44 +00002276*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002277
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002278Core and builtins
2279-----------------
2280
Nick Coghlan43832302006-04-23 17:04:07 +00002281- PEP 338: -m command line switch now delegates to runpy.run_module
2282 allowing it to support modules in packages and zipfiles
2283
Martin v. Löwisc661b882006-04-20 04:54:23 +00002284- On Windows, .DLL is not an accepted file name extension for
2285 extension modules anymore; extensions are only found if they
2286 end in .PYD.
2287
Martin v. Löwisea62d252006-04-03 10:56:49 +00002288- Bug #1421664: sys.stderr.encoding is now set to the same value as
2289 sys.stdout.encoding.
2290
Neal Norwitz92e212f2006-04-03 04:48:37 +00002291- __import__ accepts keyword arguments.
2292
Georg Brandlccadf842006-03-31 18:54:53 +00002293- Patch #1460496: round() now accepts keyword arguments.
2294
Anthony Baxter262c00a2006-03-30 10:53:17 +00002295- Fixed bug #1459029 - unicode reprs were double-escaped.
2296
Hye-Shik Changd478f342006-03-23 12:32:36 +00002297- Patch #1396919: The system scope threads are reenabled on FreeBSD
2298 5.4 and later versions.
2299
Neal Norwitze98ccf62006-03-23 05:39:47 +00002300- Bug #1115379: Compiling a Unicode string with an encoding declaration
2301 now gives a SyntaxError.
2302
Georg Brandlabd1ff82006-03-18 07:59:59 +00002303- Previously, Python code had no easy way to access the contents of a
2304 cell object. Now, a ``cell_contents`` attribute has been added
2305 (closes patch #1170323).
2306
Tim Peterscf79aac2006-03-16 01:14:46 +00002307- Patch #1123430: Python's small-object allocator now returns an arena to
2308 the system ``free()`` when all memory within an arena becomes unused
2309 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2310 freed. Some applications will see a drop in virtual memory size now,
2311 especially long-running applications that, from time to time, temporarily
2312 use a large number of small objects. Note that when Python returns an
2313 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002314 platform C library will in turn return that memory to the operating system.
2315 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002316 appears to be effective at least on Microsoft C and gcc-based systems.
2317 Thanks to Evan Jones for hard work and patience.
2318
Georg Brandl533ff6f2006-03-08 18:09:27 +00002319- Patch #1434038: property() now uses the getter's docstring if there is
2320 no "doc" argument given. This makes it possible to legitimately use
2321 property() as a decorator to produce a read-only property.
2322
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002323- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2324 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2325 of requiring an int or long in slicing and a few other contexts, enabling
2326 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2327
Neal Norwitz995acdf2006-03-07 05:01:00 +00002328- Fixed various bugs reported by Coverity's Prevent tool.
2329
Brett Cannonbf364092006-03-01 04:25:17 +00002330- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2331 new exception base class, BaseException, which has a new message attribute.
2332 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2333 Raising a string exception now raises a DeprecationWarning.
2334
Thomas Woutersfb609f42006-02-28 16:37:25 +00002335- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2336 explicitly relative, using 'from .module import name' to mean 'from the same
2337 package as this module is in. Imports without dots still default to the
2338 old relative-then-absolute, unless 'from __future__ import
2339 absolute_import' is used.
2340
Brett Cannona7446e32006-02-27 23:39:10 +00002341- Properly check if 'warnings' raises an exception (usually when a filter set
2342 to "error" is triggered) when raising a warning for raising string
2343 exceptions.
2344
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002345- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002346 The name was removed from Include/code.h.
2347
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002348- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002349
Guido van Rossum1968ad32006-02-25 22:38:04 +00002350- Patch 1433928:
2351 - The copy module now "copies" function objects (as atomic objects).
2352 - dict.__getitem__ now looks for a __missing__ hook before raising
2353 KeyError.
2354
Tim Peters84ef21c2006-02-28 20:39:06 +00002355- PEP 343: with statement implemented. Needs ``from __future__ import
2356 with_statement``. Use of 'with' as a variable will generate a warning.
2357 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002358 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002359 The following objects have __context__ methods:
2360 - The built-in file type.
2361 - The thread.LockType type.
2362 - The following types defined by the threading module:
2363 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2364 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002365
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002366- Fix the encodings package codec search function to only search
2367 inside its own package. Fixes problem reported in patch #1433198.
2368
2369 Note: Codec packages should implement and register their own
2370 codec search function. PEP 100 has the details.
2371
Tim Peters9ea89d22006-06-04 03:26:02 +00002372- PEP 353: Using ``Py_ssize_t`` as the index type.
2373
2374- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2375 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2376 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2377 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2378 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002379
Neal Norwitzfc76d632006-01-10 06:03:13 +00002380- Patch #1400181, fix unicode string formatting to not use the locale.
2381 This is how string objects work. u'%f' could use , instead of .
2382 for the decimal point. Now both strings and unicode always use periods.
2383
Neal Norwitz671b9e32006-01-09 07:07:12 +00002384- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2385 configure would break checking curses.h.
2386
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002387- Bug #959576: The pwd module is now builtin. This allows Python to be
2388 built on UNIX platforms without $HOME set.
2389
Neal Norwitzc10978f2005-12-19 06:07:16 +00002390- Bug #1072182, fix some potential problems if characters are signed.
2391
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002392- Bug #889500, fix line number on SyntaxWarning for global declarations.
2393
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002394- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2395
Neal Norwitze7214a12005-12-18 05:03:17 +00002396- Support for converting hex strings to floats no longer works.
2397 This was not portable. float('0x3') now raises a ValueError.
2398
Barry Warsaw2a38a862005-12-18 01:27:35 +00002399- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002400 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002401 is now displayed in interactive prompt banner.
2402
Georg Brandlfa166682005-12-17 21:45:17 +00002403- Implementation of PEP 341 - Unification of try/except and try/finally.
2404 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002405 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002406
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002407- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2408 now encodes backslash correctly.
2409
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002410- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2411
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002412- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002413 and long longs.
2414
Neal Norwitz67715f02005-11-09 06:59:35 +00002415- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002416 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002417 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002418
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002419- Replaced most Unicode charmap codecs with new ones using the
2420 new Unicode translate string feature in the builtin charmap
2421 codec; the codecs were created from the mapping tables available
2422 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2423 encodings now include a mapping for the Apple logo)
2424
Tim Peterse3547fd2005-12-16 23:13:57 +00002425- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002426
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002427- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002428
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002429- A new AST parser implementation was completed. The abstract
2430 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002431 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002432
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002433- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002434 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2435
Neal Norwitz708e51a2005-10-03 04:48:15 +00002436- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2437
Neal Norwitz11bd1192005-10-03 00:54:56 +00002438- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2439 Provide a warning when a directory is passed on the command line.
2440
Neal Norwitz40d37812005-10-02 01:48:49 +00002441- Fix segfault with invalid coding.
2442
2443- SF bug #772896: unknown encoding results in MemoryError.
2444
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002445- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002446 supported a __len__() method which evaluated to False when the iterator
2447 was empty.
2448
Guido van Rossum630db602005-09-20 18:49:54 +00002449- On 64-bit platforms, when __len__() returns a value that cannot be
2450 represented as a C int, raise OverflowError.
2451
Skip Montanarof8948ca2005-09-19 03:54:46 +00002452- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002453 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002454
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002455- SF bug #893549: parsing keyword arguments was broken with a few format
2456 codes.
2457
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002458- Changes donated by Elemental Security to make it work on AIX 5.3
2459 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2460 bug #105470: test_pwd fails on 64bit system (Opteron).
2461
Guido van Rossum539c6622005-09-14 17:49:54 +00002462- Changes donated by Elemental Security to make it work on HP-UX 11 on
2463 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2464
Georg Brandl4550b8d2005-08-26 06:43:52 +00002465- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002466 (fixes bug #1119418).
2467
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002468- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2469
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002470- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2471 exceptions that cause a function to exit.
2472
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002473- The implementation of set() and frozenset() was revised to use its
2474 own internal data structure. Memory consumption is reduced by 1/3
2475 and there are modest speed-ups as well. The API is unchanged.
2476
Tim Petersde7990b2005-07-17 23:45:23 +00002477- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2478
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002479- SF bug #1229429: PyObject_CallMethod failed to decrement some
2480 reference counts in some error exit cases.
2481
Tim Petersecc6e6a2005-07-10 22:30:55 +00002482- SF bug #1185883: Python's small-object memory allocator took over
2483 a block managed by the platform C library whenever a realloc specified
2484 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002485 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002486 portable way to copy data from the C-managed block into Python's
2487 small-object space without risking a memory fault. Python's small-object
2488 realloc now leaves such blocks under the control of the platform C
2489 realloc.
2490
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002491- SF bug #1232517: An overflow error was not detected properly when
2492 attempting to convert a large float to an int in os.utime().
2493
Raymond Hettinger3296e692005-06-29 23:29:56 +00002494- SF bug #1224347: hex longs now print with lowercase letters just
2495 like their int counterparts.
2496
Michael W. Hudson188d4362005-06-20 16:52:57 +00002497- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2498 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2499 interpreter states; back out that fix and do a better job (see
2500 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2501 for a longer write-up of the problem).
2502
Michael W. Hudsondf888462005-06-03 14:41:55 +00002503- SF patch #1180995: marshal now uses a binary format by default when
2504 serializing floats.
2505
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002506- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2507 the routines that promise to produce IEEE 754 binary representations
2508 of floats now simply copy bytes around.
2509
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002510- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2511 278.
2512
Brett Cannonc3647ac2005-04-26 03:45:26 +00002513- patch #1109424: int, long, float, complex, and unicode now check for the
2514 proper magic slot for type conversions when subclassed. Previously the
2515 magic slot was ignored during conversion. Semantics now match the way
2516 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002517 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002518 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002519 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002520
Barry Warsawc8d907c2005-04-19 23:43:40 +00002521- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2522 NULL, now raise an AttributeError when attempting to set or delete the
2523 attribute. Previously a TypeError was raised, but this was inconsistent
2524 with the equivalent pure-Python implementation.
2525
Michael W. Hudson774479c2005-04-18 08:46:17 +00002526- It is now safe to call PyGILState_Release() before
2527 PyEval_InitThreads() (note that if there is reason to believe there
2528 are multiple threads around you still must call PyEval_InitThreads()
2529 before using the Python API; this fix is for extension modules that
2530 have no way of knowing if Python is multi-threaded yet).
2531
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002532- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2533 disabled caused a crash.
2534
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002535- Bug #1165306: instancemethod_new allowed the creation of a method
2536 with im_class == im_self == NULL, which caused a crash when called.
2537
Tim Petersecc6e6a2005-07-10 22:30:55 +00002538- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002539 fixes the crash seen in bug #1165761
2540
Raymond Hettinger96229b12005-03-11 06:49:40 +00002541- Added two new builtins, any() and all().
2542
Brett Cannon409d8f22005-03-05 06:47:57 +00002543- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002544 (e.g., ``class C(): pass`` is no longer a syntax error).
2545 Patch #1176012 added support to the 'parser' module and 'compiler' package
2546 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002547
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002548- Patch #1115086: Support PY_LONGLONG in structmember.
2549
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002550- Bug #1155938: new style classes did not check that __init__() was
2551 returning None.
2552
Tim Petersecc6e6a2005-07-10 22:30:55 +00002553- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002554 ('\') with a specific error message.
2555
Martin v. Löwisff232d72005-03-03 09:24:38 +00002556- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2557
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002558- Bug #1124295: the __name__ attribute of file objects was
2559 inadvertently made inaccessible in restricted mode.
2560
Tim Petersecc6e6a2005-07-10 22:30:55 +00002561- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002562 an ferror() call.
2563
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002564- min() and max() now support key= arguments with the same meaning as in
2565 list.sort().
2566
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002567- The peephole optimizer now performs simple constant folding in expressions:
2568 (2+3) --> (5).
2569
Raymond Hettingera422c342005-01-11 03:03:27 +00002570- set and frozenset objects can now be marshalled. SF #1098985.
2571
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002572- Bug #1077106: Poor argument checking could cause memory corruption
2573 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002574
Jeremy Hyltonab630502005-02-04 18:44:06 +00002575- The parser did not complain about future statements in illegal
2576 positions. It once again reports a syntax error if a future
2577 statement occurs after anything other than a doc string.
2578
Neil Schemenauercf52c072005-08-12 17:34:58 +00002579- Change the %s format specifier for str objects so that it returns a
2580 unicode instance if the argument is not an instance of basestring and
2581 calling __str__ on the argument returns a unicode instance.
2582
Tim Petersf4e69282006-02-27 17:15:31 +00002583- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2584 current thread state when the auto-GIL-state machinery knows about
2585 it (since the thread state is being deleted, continuing to remember it
2586 can't help, but can hurt if another thread happens to get created with
2587 the same thread id).

2590-----------------
2591
Georg Brandl43f08a82006-03-31 18:01:16 +00002592- Patch #1380952: fix SSL objects timing out on consecutive read()s
2593
Neal Norwitz05a45592006-03-20 06:30:08 +00002594- Patch #1309579: wait3 and wait4 were added to the posix module.
2595
Anthony Baxterfa869072006-03-20 05:21:58 +00002596- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2597 In addition, the existing ulaw code was updated.
2598
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002599- RFE #567972: Socket objects' family, type and proto properties are

2780 been renamed to have only a single underscore prefix. This was done to
2781 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002782
Nick Coghlan43832302006-04-23 17:04:07 +00002783- PEP 338: new module runpy defines a run_module function to support
2784 executing modules which provide access to source code or a code object
2785 via the PEP 302 import mechanisms.
2786

2795 in attribute values.
2796
Anthony Baxterc51ee692006-04-01 00:57:31 +00002797- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002798 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002799 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002800 module will not be built.
2801
Tim Petersc17976e2006-04-01 00:26:53 +00002802- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2803 aren't officially supported here, and trying to use them will probably
2804 raise an exception some day. But dicts have been allowed, and "mostly
2805 worked", so support for them won't go away without warning.
2806
Georg Brandl338ef7d2006-03-31 18:42:16 +00002807- Bug #1445068: getpass.getpass() can now be given an explicit stream
2808 argument to specify where to write the prompt.

2825
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002826- email 4.0 package now integrated. This is largely the same as the email 3.0
2827 package that was included in Python 2.3, except that PEP 8 module names are
2828 now used (e.g. mail.message instead of email.Message). The MIME classes
2829 have been moved to a subpackage (e.g. email.mime.text instead of
2830 email.MIMEText). The old names are still supported for now. Several
2831 deprecated Message methods have been removed and lots of bugs have been
2832 fixed. More details can be found in the email package documentation.
2833
Walter Dörwald40108c92006-03-27 08:15:44 +00002834- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2835 (a subclass of tuple) that provides incremental decoders and encoders
2836 (a way to use stateful codecs without the stream API). Python functions
2837 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2838 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2839 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002841- Patch #1359365: Calling next() on a closed StringIO.String object raises
2842 a ValueError instead of a StopIteration now (like file and cString.String do).
2843 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2844 called before (like file and StringIO.StringIO do).

2920 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2921 Ronald L. Rivest offered this advice for Python:
2922
2923 "The consensus of researchers in this area (at least as
2924 expressed at the NIST Hash Function Workshop 10/31/05),
2925 is that SHA-256 is a good choice for the time being, but
2926 that research should continue, and other alternatives may
2927 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002928

3109 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003110 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003111 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003112 + Dialect parameter parsing has been re-implemented to improve error

3114 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3115 dictates.
3116 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003117 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003118 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003119 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3120 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003121 + reader now allows \r characters to be quoted (previously it only allowed
3122 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003123 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003124 + Dialect classes passed to the module are no longer instantiated by
3125 the module before being parsed (the former validation scheme required
3126 this, but the mechanism was unreliable).
3127 + The dialect registry now contains instances of the internal
3128 C-coded dialect type, rather than references to python objects.
3129 + the internal c-coded dialect type is now immutable.
3130 + register_dialect now accepts the same keyword dialect specifications
3131 as the reader and writer, allowing the user to register dialects
3132 without first creating a dialect class.
3133 + a configurable limit to the size of parsed fields has been added -
3134 previously, an unmatched quote character could result in the entire
3135 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003136 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003137 the parser field size limit (returning the former limit). The initial
3138 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003139 + A line_num attribute has been added to the reader object, which tracks
3140 the number of lines read from the source iterator. This is not
3141 the same as the number of records returned, as records can span
3142 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003143 + reader and writer objects were not being registered with the cyclic-GC.
3144 This has been fixed.
3145
Brett Cannone6539c42005-01-08 02:43:53 +00003146- _DummyThread objects in the threading module now delete self.__block that is
3147 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3148 lock primitives tend to be limited in number and thus should not be wasted on
3149 a _DummyThread object. Fixes bug #1089632.
3150
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003151- The imghdr module now detects Exif files.
3152
Raymond Hettinger6065d322004-12-20 23:51:53 +00003153- StringIO.truncate() now correctly adjusts the size attribute.
3154 (Bug #951915).
3155
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003156- locale.py now uses an updated locale alias table (built using
3157 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3158 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003159 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003160
Raymond Hettinger3557f422004-12-07 12:02:02 +00003161- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3162
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003163- the pickle module no longer accepts the deprecated None option in the
3164 args tuple returned by __reduce__().
3165
Brett Cannon84667c02004-12-07 03:25:18 +00003166- optparse now optionally imports gettext. This allows its use in setup.py.
3167
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003168- the pickle module no longer uses the deprecated bin parameter.
3169
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003170- the shelve module no longer uses the deprecated binary parameter.
3171

3173
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003174- the filecmp module no longer uses the deprecated use_statcache argument.
3175
Raymond Hettinger664347b2004-12-04 21:21:53 +00003176- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3177 extended or overridden by subclasses. Formerly, the subclassed method would
3178 be ignored by the rest of the module. (Bug #1078905).
3179
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003180- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003181 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003182
Walter Dörwald36733692004-12-22 12:50:50 +00003183- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3184 once when a size argument is given. This prevents a buffer overflow in the
3185 tokenizer with very long source lines.
3186
Barry Warsaw538561e2006-01-01 21:48:54 +00003187- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3188 immediately after creating the object, without any intervening
3189 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003190
Skip Montanaro05885812005-01-16 20:48:27 +00003191- The reconvert.quote function can now emit triple-quoted strings. The
3192 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003193
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003194- ``UserString.MutableString`` now supports negative indices in
3195 ``__setitem__`` and ``__delitem__``
3196
Greg Ward40407942005-03-05 02:53:17 +00003197- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3198 correctly.
3199
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003200- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3201 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3202 character even if the user has passed a size parameter to get a proper
3203 line ending. Remove the special handling of a "\r\n" that has been split
3204 between two lines.
3205
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003206- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3207 about illegal code points. The codec now supports PEP 293 style error
3208 handlers.
3209
Walter Dörwald78a78b02005-09-01 12:04:29 +00003210- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003211 from the input stream, so that the output is a byte string in the correct
3212 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003213
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003214- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3215 considering it exactly like a '*'.
3216
Walter Dörwald007f8df2005-10-09 19:42:27 +00003217- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3218 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003219
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003220- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3221
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003222- Patch #1413711: Certain patterns of differences were making difflib
3223 touch the recursion limit.
3224
Walter Dörwald58917a62006-03-31 15:26:22 +00003225- Bug #947906: An object oriented interface has been added to the calendar
3226 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003227 called as a script (e.g. via ``python -mcalendar``). Localized month and
3228 weekday names can be ouput (even if an exotic encoding is used) using
3229 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003230
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003231Build
3232-----
3233
Neal Norwitz602d3392006-03-31 08:21:40 +00003234- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3235 by using -mieee gcc option.
3236
Martin v. Löwis86d66262006-02-17 08:40:11 +00003237- Patch #1432345: Make python compile on DragonFly.
3238
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003239- Build support for Win64-AMD64 was added.
3240
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003241- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3242
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003243- Patch #881820: look for openpty and forkpty also in libbsd.
3244
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003245- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3246 The zlib module is now builtin on Windows.
3247
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003248- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3249
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003250- Bug #1189330: configure did not correctly determine the necessary
3251 value of LINKCC if python was built with GCC 4.0.
3252
Trent Mick8321b422005-07-26 02:29:21 +00003253- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3254 vulnerability in zlib 1.2.1 and 1.2.2.
3255
Brett Cannon08cd5982005-04-24 22:26:38 +00003256- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3257 flags that change binary compatibility. Changes were also made to
3258 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003259 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003260
Bob Ippolitoed233462005-03-29 13:47:59 +00003261- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3262 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3263 no longer exists). This configure patch makes things right.
3264
Martin v. Löwise2713be2005-03-08 15:03:08 +00003265- Bug #1158607: Build with --disable-unicode again.
3266
Brett Cannon46d96232005-02-16 00:07:19 +00003267- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3268 defined. Discovered as a result of not being able to build on OS X.
3269
Brett Cannon516592f2004-12-07 00:42:59 +00003270- setup.py now uses the directories specified in LDFLAGS using the -L option
3271 and in CPPFLAGS using the -I option for adding library and include
3272 directories, respectively, for compiling extension modules against. This has
3273 led to the core being compiled using the values in CPPFLAGS. It also removes
3274 the need for the special-casing of both DarwinPorts and Fink for darwin since
3275 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3276 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3277 Fink, ``-I/opt/local/include`` for DarwinPorts).
3278
Brett Cannon43802422005-02-10 20:48:03 +00003279- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3280 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3281 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3282 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003284C API
3285-----
3286
Tim Petersc9d78aa2006-03-26 23:27:58 +00003287- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3288 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3289 is obtained via the ``PyObject_`` family, it must be released via the
3290 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3291 always been officially true, but when Python's small-object allocator was
3292 introduced, an attempt was made to cater to a few extension modules
3293 discovered at the time that obtained memory via ``PyObject_New`` but
3294 released it via ``PyMem_DEL``. It's years later, and if such code still
3295 exists it will fail now (probably with segfaults, but calling wrong
3296 low-level memory management functions can yield many symptoms).
3297
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003298- Added a C API for set and frozenset objects.
3299
Raymond Hettinger66517482004-12-03 11:45:13 +00003300- Removed PyRange_New().
3301
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003302- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3303 mapping argument now. This string is used as a mapping table. Byte values
3304 greater than the length of the string and 0xFFFE are treated as undefined
3305 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003312
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003313- Patch #1276356: New resource "urlfetch" is implemented. This enables
