12Core and builtins
13-----------------
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000014
Amaury Forgeot d'Arc3b335ff2008-10-30 21:40:05 +000015- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
16 method does not return iterators for the 4th and 5th items.
17
Amaury Forgeot d'Arcb50f9922008-09-26 22:46:01 +000018- Issue #3967: Fixed a crash in the count() and find() methods of string-like
19 objects, when the "start" parameter is a huge value.
20
Benjamin Petersond1c7d072008-09-25 20:46:05 +000021- Issue #3936: The parser warnings for using "as" and "with" as variable names
22 didn't fire after import statements.
23
Amaury Forgeot d'Arcafa0d582008-09-01 20:05:08 +000024- Issue #3751: str.rpartition would perform a left-partition when called with
25 a unicode argument.
26
Georg Brandl45c33ce2008-08-11 09:13:26 +000027- Issue #3537: Fix an assertion failure when an empty but presized dict
28 object was stored in the freelist.
29
Neal Norwitz4f3be8a2008-07-31 17:08:14 +000030- Apply security patches from Apple.
31
Neal Norwitz83ac0142008-07-28 05:06:20 +000032- Issue #2620: Overflow checking when allocating or reallocating memory
33 was not always being done properly in some python types and extension
34 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
35 all been updated to perform better checks and places in the code that
36 would previously leak memory on the error path when such an allocation
37 failed have been fixed.
38
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +000039- Issue #2242: Fix a crash when decoding invalid utf-7 input on certain
40 Windows / Visual Studio versions.
41
Mark Dickinsonab396e02008-07-16 11:04:17 +000042- Issue #3360: Fix incorrect parsing of '020000000000.0', which
43 produced a ValueError instead of giving the correct float.
44
Amaury Forgeot d'Arcceda6a62008-07-01 20:52:56 +000045- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
46 set to a custom object whose write() method happens to install
47 another file in sys.stdout.
48
Amaury Forgeot d'Arcb15bdf72008-07-01 20:59:49 +000049- Issue #3088: Corrected a race condition in classes derived from
50 threading.local: the first member set by a thread could be saved in
51 another thread's dictionary.
52
Amaury Forgeot d'Arc3255e132008-06-16 19:22:42 +000053- Issue #3100: Corrected a crash on deallocation of a subclassed weakref which
54 holds the last (strong) reference to its referent.
55
Guido van Rossumaa975432008-04-10 22:43:58 +000056- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
57 having a self-referential tuple, which is possible from C code. Nor did
58 object's tp_str consider that a type's tp_str could do something that could
59 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
60 respectively, fixed the issues. (Backport of r58288 from trunk.)
61
Georg Brandld9f1da02008-03-29 01:50:46 +000062- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
63 cannot be executed.
64
Amaury Forgeot d'Arc8432d862008-03-28 20:45:42 +000065- The compilation of a class nested in another class used to leak one
66 reference on the outer class name.
67
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000068- Issue #1477: With narrow Unicode builds, the unicode escape sequence
69 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
70 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
71 UTF-16 surrogates are generated in this case, like normal unicode literals
72 and the 'unicode-escape' codec.
73
Neal Norwitzb3635f92008-03-18 04:17:36 +000074- Issue #2321: use pymalloc for unicode object string data to reduce
75 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +000076
Sean Reifscheider4af861c2008-03-20 17:39:31 +000077- Issue #2238: Some syntax errors in *args and **kwargs expressions could give
78 bogus error messages.
79
Gregory P. Smith14acde32008-04-09 23:41:13 +000080- Issue #2587: In the C API, PyString_FromStringAndSize() takes a signed size
81 parameter but was not verifying that it was greater than zero. Values
82 less than zero will now raise a SystemError and return NULL to indicate a
83 bug in the calling C code.
84
Gregory P. Smith9aa040d2008-06-02 00:07:25 +000085- Issue #2588, #2589: Fix potential integer underflow and overflow
86 conditions in the PyOS_vsnprintf C API function.
87
Gregory P. Smithcae7f882008-09-07 06:44:12 +000088- Issue #1204: The configure script now tests for additional libraries
89 that may be required when linking against readline. This fixes issues
90 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
Georg Brandld9f1da02008-03-29 01:50:46 +000091
Gregory P. Smitha7a94a02008-09-22 00:22:44 +000092- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
93 library targets in the Makefile.

96-------
97
Thomas Heller3e06fae2008-10-18 21:33:44 +000098- Assigning methods to ctypes.Structure and ctypes.Union subclasses
99 after creation of the class does now work correctly. See Issue #1700288.
100
Brett Cannon70f1192d2008-09-29 03:57:24 +0000101- Issue #3895: _lsprof could be crashed with an external timer that did not
102 return a float when a Profiler object is garbage collected.
103

110 its symbolic link.
111
Thomas Heller275e2292008-08-19 17:17:37 +0000112- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
113 api functions without holding the GIL, which could lead to a fatal
114 error when they failed.
115
Amaury Forgeot d'Arc22679b82008-08-18 19:33:42 +0000116- Issue #2234: distutils failed for some versions of the cygwin compiler. The
117 version reported by these tools does not necessarily follow the python
118 version numbering scheme, so the module is less strict when parsing it.
119
Hirokazu Yamamoto1d63a452008-08-17 09:49:10 +0000120- Issue #2222: Fixed reference leak when occured os.rename()
121 fails unicode conversion on 2nd parameter. (windows only)
122

129
Brett Cannonff931572008-07-13 01:20:19 +0000130- Issue #3339: dummy_thread.acquire() could return None which is not a valid
131 return value.
132
Raymond Hettinger75ee9eb2008-06-16 01:49:18 +0000133- Issue #3116 and #1792: Fix quadratic behavior in marshal.dumps().
134
Thomas Hellerf3bb2832008-04-25 19:55:19 +0000135- Issue #2682: ctypes callback functions no longer contain a cyclic
136 reference to themselves.
137
Amaury Forgeot d'Arc8d904c32008-04-22 21:17:18 +0000138- Issue #2670: Fix a failure in urllib2.build_opener(), when passed two
139 handlers that derive the same default base class.
140

142 string literals; previously, ["" ""] was rendered as [""""], which is
143 incorrect python code.
144
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +0000145- Issue #2482: Make sure that the coefficient of a Decimal is always
146 stored as a str instance, not as a unicode instance. This ensures
147 that str(Decimal) is always an instance of str. This fixes a
148 regression from Python 2.5.1 to Python 2.5.2.
149
Mark Dickinson26c25d92008-03-25 14:35:25 +0000150- Issue #2478: fix failure of decimal.Decimal(0).sqrt()

161 root directory, and also exclude .hg, .git, .bzr, and _darcs.
162
Andrew M. Kuchling37d4f7b2008-02-23 19:06:54 +0000163- Bug #1389051: imaplib causes excessive memory fragmentation when reading
164 large messages.
165
Andrew M. Kuchling664553a2008-02-23 19:30:59 +0000166- Bug #1389051, 1092502: fix excessively large memory allocations when
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000167 calling .read() on a socket object wrapped with makefile().
Andrew M. Kuchling664553a2008-02-23 19:30:59 +0000168
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +0000169- Bug #1433694: minidom's .normalize() failed to set .nextSibling for

173 stdout and stderr fds rather than leaving them open until the
174 instance is destroyed.
175
Gregory P. Smithf8f30fa2008-07-06 04:04:07 +0000176- Issue #2632: Prevent socket.read(bignumber) from over allocating memory
177 in the common case when the data is returned from the underlying socket
178 in increments much smaller than bignumber.
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +0000179

Martin v. Löwis897704d2007-06-08 17:29:40 +0000266Core and builtins
267-----------------
268
Martin v. Löwis73c01d42008-02-14 11:26:18 +0000269- Added checks for integer overflows, contributed by Google. Some are
270 only available if asserts are left in the code, in cases where they
271 can't be triggered from Python code.
272
Amaury Forgeot d'Arc3e5f8a62008-02-08 01:05:21 +0000273- Issue #2045: Fix an infinite recursion triggered when printing a subclass of
274 collections.defaultdict, if its default_factory is set to a bound method.
275
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000276- Issue #1920: "while 0" statements were completely removed by the compiler,
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000277 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000278 the condition is false. Now the compiler correctly emits bytecode for the
279 "else" suite.
280
Guido van Rossumd933e0a2008-01-24 18:28:37 +0000281- A few crashers fixed: weakref_in_del.py (issue #1377858);

287 subclassing from both ModuleType and another built-in types.
288
Christian Heimesd2f4cb82008-01-23 14:20:41 +0000289- Bug #1915: Python compiles with --enable-unicode=no again. However
290 several extension methods and modules do not work without unicode
291 support.
292
Mark Dickinson2bebadf2008-01-21 21:54:47 +0000293- Issue #1678380: distinction between 0.0 and -0.0 was lost during constant
294 folding optimization. This was a regression from Python 2.4.
295
Georg Brandl78d50cc2008-01-21 18:36:54 +0000296- Issue #1882: when compiling code from a string, encoding cookies in the

876
Georg Brandld59ea472007-03-08 18:37:35 +0000877- unittest now verifies more of its assumptions. In particular, TestCase
878 and TestSuite subclasses (not instances) are no longer accepted in
879 TestSuite.addTest(). This should cause no incompatibility since it
880 never made sense with ordinary subclasses -- the failure just occurred
881 later, with a more cumbersome exception.

1232=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001233
Anthony Baxterb4096662006-08-16 03:42:26 +00001234*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001235
1236Core and builtins
1237-----------------
1238
Neal Norwitz24b6f202006-09-05 04:43:56 +00001239- Fix infinite recursion when subclassing long and overriding __hash__.
1240
1241- Fix concatenation (+=) of long strings.
1242
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001243- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001244 compared equal or unequal to a string and a UnicodeDecodeError
1245 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001246
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001247 Instead, the equal (==) and unequal (!=) comparison operators will
1248 now issue a UnicodeWarning and interpret the two objects as
1249 unequal. The UnicodeWarning can be filtered as desired using
1250 the warning framework, e.g. silenced completely, turned into an
1251 exception, logged, etc.
1252
1253 Note that compare operators other than equal and unequal will still
1254 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001255
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001256- Fix segfault when doing string formatting on subclasses of long.
1257
1258- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1259 with new-style classes.
1260
1261- Fix bug related to __len__ functions returning negative values with
1262 classic classes.
1263
1264- Patch #1538606, Fix __index__() clipping. There were some problems
1265 discovered with the API and how integers that didn't fit into Py_ssize_t
1266 were handled. This patch attempts to provide enough alternatives
1267 to effectively use __index__.
1268
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001269- Bug #1536021: __hash__ may now return long int; the final hash
1270 value is obtained by invoking hash on the long int.
1271
Thomas Hellerab1049c2006-08-08 17:37:00 +00001272- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1273
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001274- Bug #1535165: fixed a segfault in input() and raw_input() when
1275 sys.stdin is closed.
1276
Thomas Heller74d36f02006-08-04 18:17:40 +00001277- On Windows, the PyErr_Warn function is now exported from
1278 the Python dll again.
1279
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001280- Bug #1191458: tracing over for loops now produces a line event
1281 on each iteration. Fixing this problem required changing the .pyc
1282 magic number. This means that .pyc files generated before 2.5c1
1283 will be regenerated.
1284
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001285- Bug #1333982: string/number constants were inappropriately stored
1286 in the byte code and co_consts even if they were not used, ie
1287 immediately popped off the stack.
1288
Georg Brandle9462c72006-08-04 18:03:37 +00001289- Fixed a reference-counting problem in property().

1292Library
1293-------
1294
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001295- Fix a bug in the ``compiler`` package that caused invalid code to be
1296 generated for generator expressions.
1297
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001298- The distutils version has been changed to 2.5.0. The change to
1299 keep it programmatically in sync with the Python version running
1300 the code (introduced in 2.5b3) has been reverted. It will continue
1301 to be maintained manually as static string literal.
1302
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001303- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001304 and this cannot be converted to the required C type, an exception is
1305 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001306 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001307
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001308- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001309 an exception.
1310
Tim Peterscbdd3502006-09-05 01:47:53 +00001311- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001312 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001313 workarounds for clocks with low resolution, to stop the code yielding
1314 duplicate UUIDs.
1315
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001316- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1317 before raising SystemExit, allowing IDLE to honor quit() and exit().
1318
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001319- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1320
Georg Brandl7a1af772006-08-14 21:55:28 +00001321- Patch #1536071: trace.py should now find the full module name of a
1322 file correctly even on Windows.
1323
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001324- logging's atexit hook now runs even if the rest of the module has
1325 already been cleaned up.
1326
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001327- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001328
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001329- Bug #1531405, format_exception no longer raises an exception if
1330 str(exception) raised an exception.
1331
Neil Schemenauer06ded092006-08-04 16:20:30 +00001332- Fix a bug in the ``compiler`` package that caused invalid code to be
1333 generated for nested functions.

Georg Brandl3335a7a2006-08-14 21:42:55 +00001343- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1344 raises the correct exceptions.
1345
Thomas Heller1ce433e2006-08-14 16:20:04 +00001346- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1347 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1348
Thomas Heller86720042006-08-14 11:17:48 +00001349- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1350 uses the _as_parameter_ attribute when objects are passed to foreign
1351 function calls. The ctypes version number was changed to 1.0.1.
1352
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001353- Bug #1530559, struct.pack raises TypeError where it used to convert.
1354 Passing float arguments to struct.pack when integers are expected
1355 now triggers a DeprecationWarning.
1356
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001357

Neal Norwitza1f10902006-07-12 07:28:29 +00001402
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001403*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001404
1405Core and builtins
1406-----------------
1407
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001408- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001409 returned a long (see PEP 353).
1410
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001411- Bug #1515471: string.replace() accepts character buffers again.
1412
Neal Norwitz07aadb12006-07-30 06:55:48 +00001413- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1414 This provides the proper warning for struct.pack().
1415 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1416
Neal Norwitz0d62a062006-07-30 06:53:31 +00001417- Patch #1531113: Fix augmented assignment with yield expressions.
1418 Also fix a SystemError when trying to assign to yield expressions.
1419
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001420- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1421 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1422 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1423 excessive filesystem operations during imports.
1424
Tim Petersbc24eee2006-07-27 01:14:53 +00001425- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1426 operations on signed longs that are formally undefined by C.
1427 Unfortunately, at least one compiler now cares about that, so complicated
1428 the code to make that compiler happy again.
1429
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001430- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1431
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001432- Patch #1232023: Stop including current directory in search
1433 path on Windows.
1434
Neal Norwitze1fdb322006-07-21 05:32:28 +00001435- Fix some potential crashes found with failmalloc.
1436
Neal Norwitze7563102006-07-17 01:00:16 +00001437- Fix warnings reported by Klocwork's static analysis tool.
1438

1440 had more than 255 blank lines.
1441
Georg Brandl9dceedb2006-07-12 15:31:17 +00001442- Patch #1521179: Python now accepts the standard options ``--help`` and
1443 ``--version`` as well as ``/?`` on Windows.
1444
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001445- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001446 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001447 This means that .pyc files generated before 2.5b3 will be regenerated.

Tim Peters112aad32006-07-19 00:03:19 +00001449- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001450 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001451 new ``sys._current_frames()`` returns a dictionary with one entry,
1452 mapping the faux "thread id" 0 to the current frame.

1459
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001460- Correction of patch #1455898: In the mbcs decoder, set final=False
1461 for stream decoder, but final=True for the decode function.
1462
Georg Brandl07fec3a2006-08-01 18:49:24 +00001463- os.urandom no longer masks unrelated exceptions like SystemExit or
1464 KeyboardInterrupt.
1465
Tim Peters4643c2f2006-08-10 22:45:34 +00001466- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001467 shutil.copytree on Windows
1468
Georg Brandle34ac7c2006-07-30 11:07:23 +00001469- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1470 refers to file descriptors, not file objects.
1471
Tim Peterscbdd3502006-09-05 01:47:53 +00001472- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001473 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001474 #1513611, and probably others.
1475
Georg Brandledd9b0d2006-07-29 09:33:26 +00001476- Bug #1441397: The compiler module now recognizes module and function
1477 docstrings correctly as it did in Python 2.4.
1478
Tim Peters6f681472006-07-27 23:44:37 +00001479- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1480 lost that tests are sorted by name before being run. This rarely
1481 matters for well-written tests, but can create baffling symptoms if
1482 side effects from one test to the next affect outcomes. ``DocTestFinder``
1483 has been changed to sort the list of tests it returns.
1484
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001485- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001486 in sync with sys.version_info[:3].

Martin v. Löwis9298eff2006-07-26 12:12:56 +00001488- Bug #978833: Really close underlying socket in _socketobject.close.
1489
Georg Brandldb232dc2006-08-20 13:15:43 +00001490- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1491 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001492
Georg Brandlcf0c1722006-07-26 07:23:32 +00001493- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1494 to recursive calls and call it with the failing package name.
1495
Martin v. Löwis0b483032006-07-25 09:53:12 +00001496- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1497
Georg Brandlc13c34c2006-07-24 14:09:56 +00001498- Patch #1515343: Fix printing of deprecated string exceptions with a
1499 value in the traceback module.
1500
Greg Ward48fae7a2006-07-23 16:05:51 +00001501- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1502
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001503- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1504
Brett Cannoncaebe222006-07-18 04:41:36 +00001505- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1506 argument tuple. For arguments where zero is illegal, the value is forced to
1507 the minimum value that is correct. This is to support an undocumented but
1508 common way people used to fill in inconsequential information in the time
1509 tuple pre-2.4.
1510
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001511- Patch #1220874: Update the binhex module for Mach-O.
1512
Barry Warsawb110bad2006-07-21 14:51:07 +00001513- The email package has improved RFC 2231 support, specifically for
1514 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1515 (name*0=<blah>) parameter continuations. This may change the types of
1516 values returned from email.message.Message.get_param() and friends.
1517 Specifically in some cases where non-encoded continuations were used,
1518 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1519 will just return the string (since non-encoded continuations don't have
1520 charset and language parts).
1521
1522 Also, whereas % values were decoded in all parameter continuations, they are
1523 now only decoded in encoded parameter parts.
1524
Ronald Oussoren3075e162006-07-25 20:28:55 +00001525- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1526
1527- Bug #1517996: IDLE now longer shows the default Tk menu when a
1528 path browser, class browser or debugger is the frontmost window on MacOS X
1529
Barry Warsaw00decd72006-07-27 23:43:15 +00001530- Patch #1520294: Support for getset and member descriptors in types.py,
1531 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1532 of an object against these built-in types and more importantly, for getting
1533 their docstrings printed in the interactive interpreter's help() function.

1537-----------------
1538
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001539- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1540 a socket operation on a socket with a timeout, the exception will be
1541 caught correctly. Previously, the exception was not caught.
1542
Thomas Heller1393d6a2006-07-28 21:43:20 +00001543- Patch #1529514: The _ctypes extension is now compiled on more
1544 openbsd target platforms.
1545
Tim Peters9cab5932006-07-28 00:30:00 +00001546- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1547 a memory leak, affecting pickles and deep copies.
1548
Tim Petersbc24eee2006-07-27 01:14:53 +00001549- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1551
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001552- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1553
Thomas Hellerce049a02006-07-14 17:51:14 +00001554- Patch #1521817: Index range checking on ctypes arrays containing
1555 exactly one element enabled again. This allows iterating over these
1556 arrays, without the need to check the array size before.
1557
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001558- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001559 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001560 /dev/null in certain cases; this is now fixed.
1561
Thomas Heller47d7a062006-07-12 08:43:47 +00001562- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1563 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001564
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001565- Because of a misspelled preprocessor symbol, ctypes was always
1566 compiled without thread support; this is now fixed.
1567
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001568- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1569 methods now allow their database parameter to be None as the
1570 sleepycat API allows.
1571
Matt Flemingec926502006-07-28 11:27:27 +00001572- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1573 bluetooth API compared with Linux and FreeBSD.
1574
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001575Tests
1576-----
1577
1578- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1579 how long the test file should take to play. Now accepts taking 2.93 secs
1580 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1581
Georg Brandl4793aa32006-07-28 18:31:39 +00001582- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1583 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1584 run via ``regrtest.py``. Now they do.

1593
1594- PythonLauncher now works correctly when the path to the script contains
1595 characters that are treated specially by the shell (such as quotes).
1596
1597- Bug #1527397: PythonLauncher now launches scripts with the working directory
1598 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001599 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001600 expect.

1609-----------------
1610
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001611- Bug #1441486: The literal representation of -(sys.maxint - 1)
1612 again evaluates to a int object, not a long.
1613
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001614- Bug #1501934: The scope of global variables that are locally assigned
1615 using augmented assignment is now correctly determined.
1616
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001617- Bug #927248: Recursive method-wrapper objects can now safely
1618 be released.
1619
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001620- Bug #1417699: Reject locale-specific decimal point in float()
1621 and atof().
1622
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001623- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1624 omit a default "error" argument for NULL pointer. This allows
1625 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001626
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001627- Bug #1519018: 'as' is now validated properly in import statements.
1628
Neal Norwitz28746ab2006-07-09 22:14:42 +00001629- On 64 bit systems, int literals that use less than 64 bits are
1630 now ints rather than longs.
1631
Neal Norwitzed657552006-07-10 00:04:44 +00001632- Bug #1512814, Fix incorrect lineno's when code at module scope
1633 started after line 256.
1634
Tim Peters32a83612006-07-10 21:08:24 +00001635- New function ``sys._current_frames()`` returns a dict mapping thread
1636 id to topmost thread stack frame. This is for expert use, and is
1637 especially useful for debugging application deadlocks. The functionality
1638 was previously available in Fazal Majid's ``threadframe`` extension
1639 module, but it wasn't possible to do this in a wholly threadsafe way from
1640 an extension.

1657
Thomas Woutersadd19112006-07-05 11:03:49 +00001658- string.Template() now correctly handles tuple-values. Previously,
1659 multi-value tuples would raise an exception and single-value tuples would
1660 be treated as the value they contain, instead.
1661
Martin v. Löwisede77f52006-07-03 13:01:35 +00001662- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1669 degrees and radians.
1670
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001671- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001672 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001673
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001674- Bug #1514703: Only setup canvas window in turtle when the canvas
1675 is created.
1676
Martin v. Löwis7596e832006-07-01 15:33:37 +00001677- Bug #1513223: .close() of a _socketobj now releases the underlying
1678 socket again, which then gets closed as it becomes unreferenced.
1679
Fred Drake10497c82006-06-29 02:57:48 +00001680- Bug #1504333: Make sgmllib support angle brackets in quoted
1681 attribute values.

1683- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1684 sgmllib ('[' and ']' were not accepted).
1685
Georg Brandl1be63af2006-06-28 20:23:25 +00001686- Fix a bug in the turtle module's end_fill function.
1687
Brett Cannon53ab5b72006-06-22 16:49:14 +00001688- Bug #1510580: The 'warnings' module improperly required that a Warning
1689 category be either a types.ClassType and a subclass of Warning. The proper
1690 check is just that it is a subclass with Warning as the documentation states.
1691
Georg Brandlad29e632006-06-21 17:45:17 +00001692- The compiler module now correctly compiles the new try-except-finally
1693 statement (bug #1509132).
1694
Neal Norwitz60373cd2006-06-22 06:30:50 +00001695- The wsgiref package is now installed properly on Unix.
1696
Vinay Sajip28e57612006-07-01 10:45:20 +00001697- A bug was fixed in logging.config.fileConfig() which caused a crash on
1698 shutdown when fileConfig() was called multiple times.
1699
Gerhard Häring762fbd32006-07-02 17:48:30 +00001700- The sqlite3 module did cut off data from the SQLite database at the first
1701 null character before sending it to a custom converter. This has been fixed
1702 now.

Tim Peters112aad32006-07-19 00:03:19 +00001707- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1708 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1709 The patch makes sockets use poll() internally where available.

Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001711- Assigning None to pointer type fields in ctypes structures possible
1712 overwrote the wrong fields, this is fixed now.
1713
1714- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1715 on non-Windows platforms.
1716
1717- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1718 integer or long, without range checking.
1719
1720- Patch #1517790: It is now possible to use custom objects in the ctypes
1721 foreign function argtypes sequence as long as they provide a from_param
1722 method, no longer is it required that the object is a ctypes type.
1723
1724- The '_ctypes' extension module now works when Python is configured
1725 with the --without-threads option.

1742
Tim Peters32a83612006-07-10 21:08:24 +00001743- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001744 Previously, the slight difference could cause compilation errors of the
1745 'zlib' module on systems with more than one version of zlib.
1746
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001747- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +00001777
1778Core and builtins
1779-----------------
1780
Georg Brandla56b9152006-06-19 06:35:54 +00001781- Patch #1507676: Error messages returned by invalid abstract object operations
1782 (such as iterating over an integer) have been improved and now include the
1783 type of the offending object to help with debugging.
1784
Brett Cannonea3912b2006-06-13 21:46:41 +00001785- Bug #992017: A classic class that defined a __coerce__() method that returned
1786 its arguments swapped would infinitely recurse and segfault the interpreter.
1787
Neal Norwitz909eb122006-06-12 02:13:21 +00001788- Fix the socket tests so they can be run concurrently.
1789
Neal Norwitzb9845e72006-06-12 02:11:18 +00001790- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001791 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001792
Brett Cannon22565aa2006-06-09 22:31:23 +00001793- Bug #532646: object.__call__() will continue looking for the __call__
1794 attribute on objects until one without one is found. This leads to recursion
1795 when you take a class and set its __call__ attribute to an instance of the
1796 class. Originally fixed for classic classes, but this fix is for new-style.
1797 Removes the infinite_rec_3 crasher.
1798
Georg Brandl24250812006-06-09 18:45:48 +00001799- The string and unicode methods startswith() and endswith() now accept
1800 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1801
Brett Cannonde3b0522006-06-08 17:00:45 +00001802- Buffer objects, at the C level, never used the char buffer
1803 implementation even when the char buffer for the wrapped object was
1804 explicitly requested (originally returned the read or write buffer).
1805 Now a TypeError is raised if the char buffer is not present but is
1806 requested.
1807
Georg Brandlddbaa662006-06-04 21:56:52 +00001808- Patch #1346214: Statements like "if 0: suite" are now again optimized
1809 away like they were in Python 2.4.
1810
Georg Brandlb7c8f542006-05-27 12:30:25 +00001811- Builtin exceptions are now full-blown new-style classes instead of
1812 instances pretending to be classes, which speeds up exception handling
1813 by about 80% in comparison to 2.5a2.
1814
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001815- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1816 Unicode 4.1.
1817
Georg Brandlf4ef1162006-05-26 18:03:31 +00001818- Patch #921466: sys.path_importer_cache is now used to cache valid and
1819 invalid file paths for the built-in import machinery which leads to
1820 fewer open calls on startup.
1821
Tim Peters696cf432006-05-24 21:10:40 +00001822- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1823 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1824 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1825 the number of input digits (it was and remains linear-time for bases
1826 2, 4, 8, 16 and 32).
1827
Tim Petersb713ec22006-05-23 18:45:30 +00001828- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1829 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1830 an integer close to ``sys.maxint``. This was repaired by patch
1831 #1335972, which also gives a nice speedup.
1832
Richard Jonescebbefc2006-05-23 18:28:17 +00001833- Patch #1337051: reduced size of frame objects.
1834
1835- PyErr_NewException now accepts a tuple of base classes as its
1836 "base" parameter.
1837
Richard Jones7c88dcc2006-05-23 10:37:38 +00001838- Patch #876206: function call speedup by retaining allocated frame
1839 objects.
1840
Georg Brandl7b90e162006-05-18 07:01:27 +00001841- Bug #1462152: file() now checks more thoroughly for invalid mode
1842 strings and removes a possible "U" before passing the mode to the
1843 C library function.
1844
Neal Norwitz1004a532006-05-15 07:17:23 +00001845- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1846
Neal Norwitz373f0a72006-05-15 07:04:36 +00001847- Bug #1487966: Fix SystemError with conditional expression in assignment
1848
Martin v. Löwis879768d2006-05-11 13:28:43 +00001849- WindowsError now has two error code attributes: errno, which carries
1850 the error values from errno.h, and winerror, which carries the error
1851 values from winerror.h. Previous versions put the winerror.h values
1852 (from GetLastError()) into the errno attribute.
1853
Martin v. Löwis77736712006-05-04 05:51:03 +00001854- Patch #1475845: Raise IndentationError for unexpected indent.
1855
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001856- Patch #1479181: split open() and file() from being aliases for each other.
1857
Tim Peters44bd9862006-06-01 13:49:23 +00001858- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1859 methods were always silently ignored by dictionaries when comparing keys.
1860 They are now passed through (except when using the C API function
1861 ``PyDict_GetItem()``, whose semantics did not change).
1862
1863- Bug #1456209: In some obscure cases it was possible for a class with a
1864 custom ``__eq__()`` method to confuse dict internals when class instances
1865 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1866 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001868Extension Modules
1869-----------------
1870
Trent Mick960a3f82006-06-28 20:30:41 +00001871- Bug #1295808: expat symbols should be namespaced in pyexpat
1872
1873- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1874
Brett Cannon6ee7d012006-06-08 16:23:04 +00001875- Change binascii.hexlify to accept a read-only buffer instead of only a char
1876 buffer and actually follow its documentation.
1877
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001878- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1879
Nick Coghlanc649ec52006-05-29 12:43:05 +00001880- Patch #1478788 (modified version): The functional extension module has
1881 been renamed to _functools and a functools Python wrapper module added.
1882 This provides a home for additional function related utilities that are
1883 not specifically about functional programming. See PEP 309.
1884
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001885- Patch #1493701: performance enhancements for struct module.
1886
Georg Brandl378d5922006-05-17 14:26:50 +00001887- Patch #1490224: time.altzone is now set correctly on Cygwin.
1888
Georg Brandl8d3342b2006-05-16 07:38:27 +00001889- Patch #1435422: zlib's compress and decompress objects now have a
1890 copy() method.
1891
Andrew MacIntyre92913322006-06-13 15:04:24 +00001892- Patch #1454481: thread stack size is now tunable at runtime for thread
1893 enabled builds on Windows and systems with Posix threads support.
1894
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001895- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1896 (up to the system limit of 32K characters).
1897
1898- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1899 As a result, these functions now raise WindowsError instead of OSError.
1900
Tim Peters7a822da2006-05-25 21:50:17 +00001901- ``time.clock()`` on Win64 should use the high-performance Windows
1902 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1903 Windows platforms).
1904
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001905- Calling Tk_Init twice is refused if the first call failed as that
1906 may deadlock.
1907
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001908- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1909 accept it without potentially using an uninitialized pointer.
1910
1911- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1912 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1913 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001914
Gregory P. Smith372b5832006-06-05 18:48:21 +00001915- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001916 [pybsddb project SF patch number 1466734]
1917
Gregory P. Smith372b5832006-06-05 18:48:21 +00001918- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1919 parameter is supplied. [SF pybsddb bug #1477863]
1920
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001921- bsddb: the __len__ method of a DB object has been fixed to return correct
1922 results. It could previously incorrectly return 0 in some cases.
1923 Fixes SF bug 1493322 (pybsddb bug 1184012).
1924
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001925- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1926 aborts the db transaction safely when a modifier callback fails.
1927 Fixes SF python patch/bug #1408584.
1928
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001929- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001930 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001931 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1932 database calls that would previously deadlock. [SF python bug #775414]
1933
Vinay Sajip28e57612006-07-01 10:45:20 +00001934- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1940-------
1941
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001942- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1943 functions.
1944
Martin v. Löwis3798da02006-06-17 18:44:27 +00001945- Patch #812986: Update turtle output even if not tracing.
1946
Vinay Sajip28e57612006-07-01 10:45:20 +00001947- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001948 Tkinter.BaseWidget.
1949
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001950- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1951
Martin v. Löwis337487e2006-06-17 09:15:14 +00001952- Patch #763580: Add name and value arguments to Tkinter variable
1953 classes.
1954
Georg Brandl83cc0d02006-06-14 08:50:03 +00001955- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1956 mime.types file for determining MIME types.
1957
Georg Brandl2605ca82006-06-14 06:08:31 +00001958- Bug #1339007: Shelf objects now don't raise an exception in their
1959 __del__ method when initialization failed.
1960
Martin v. Löwisd8251432006-06-14 05:21:04 +00001961- Patch #1455898: The MBCS codec now supports the incremental mode for
1962 double-byte encodings.
1963
Tim Peters43898b42006-06-14 04:09:25 +00001964- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1965 guarantee that adjacent triples in the return list always describe
1966 non-adjacent blocks. Previously, a pair of matching blocks could end
1967 up being described by multiple adjacent triples that formed a partition
1968 of the matching pair.
1969
Greg Ward0e0c9f42006-06-11 16:24:11 +00001970- Bug #1498146: fix optparse to handle Unicode strings in option help,
1971 description, and epilog.
1972
Greg Wardd1c797e2006-06-11 14:42:41 +00001973- Bug #1366250: minor optparse documentation error.
1974
Greg Ward7f547402006-06-11 00:40:49 +00001975- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1976 clarify docs.
1977
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001978- The wsgiref package has been added to the standard library.
1979
Nick Coghlan676725d2006-06-08 13:54:49 +00001980- The functions update_wrapper() and wraps() have been added to the functools
1981 module. These make it easier to copy relevant metadata from the original
1982 function when writing wrapper functions.
1983
Tim Petersd6a9eef2006-06-05 01:48:21 +00001984- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1985 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001986
Martin v. Löwis3f767792006-06-04 19:36:28 +00001987- Patch #1359618: Speed up charmap encoder by using a trie structure
1988 for lookup.
1989
Tim Petersd609b1a2006-06-02 23:22:51 +00001990- The functions in the ``pprint`` module now sort dictionaries by key
1991 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1992 if and only if its display required more than one line, although that
1993 wasn't documented. The new behavior increases predictability; e.g.,
1994 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1995
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001996- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1997 (thanks for J. J. Lee).
1998
Georg Brandl2b330372006-05-28 20:23:12 +00001999- Patch #1496206: improve urllib2 handling of passwords with respect to
2000 default HTTP and HTTPS ports.
2001
George Yoshidaf3c65de2006-05-28 16:39:09 +00002002- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
2003
Bob Ippolito7298f272006-05-23 18:43:47 +00002004- Patch #1281707: speed up gzip.readline.
2005
Georg Brandlb89316f2006-05-17 15:51:16 +00002006- Patch #1180296: Two new functions were added to the locale module:
2007 format_string() to get the effect of "format % items" but locale-aware,
2008 and currency() to format a monetary number with currency sign.
2009
Georg Brandle3a25832006-05-17 14:56:04 +00002010- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2011 and several features added, such as speed and geometry control.
2012
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002013- Patch #1488881: add support for external file objects in bz2 compressed
2014 tarfiles.
2015
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002016- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2017 stdout arguments, making it possible to redirect input and output
2018 for remote debugging.
2019
2020- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2021 a couple of issues, notably handling of long file names using the
2022 GNU LONGNAME extension.
2023
2024- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002066What's New in Python 2.5 alpha 2?
2067=================================
2068
2069*Release date: 27-APR-2006*
2070
2071Core and builtins
2072-----------------
2073
Thomas Heller1b046642006-04-18 18:51:06 +00002074- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2075 by converting these apis from macros into exported functions again:
2076
2077 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2078 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2079 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2080 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2081 PyRun_String Py_CompileString
2082
Martin v. Löwis45294a92006-04-18 06:24:08 +00002083- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2084
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002085- All uses of PyStructSequence_InitType have been changed to initialize
2086 the type objects only once, even if the interpreter is initialized
2087 multiple times.
2088
Neal Norwitz61546162006-04-14 05:20:28 +00002089- Bug #1454485, array.array('u') could crash the interpreter. This was
2090 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2091 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2092
2093- Py_UNICODE is unsigned. It was always documented as unsigned, but
2094 due to a bug had a signed value in previous versions.
2095
Tim Peters3a5e8b12006-04-11 01:44:07 +00002096- Patch #837242: ``id()`` of any Python object always gives a positive
2097 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2098 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002099 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002100 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002101
Tim Peters3a5e8b12006-04-11 01:44:07 +00002102 def __hash__(self):
2103 return id(self) # WRONG
2104
2105 because a hash result must be a (short) Python int but it was always
2106 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002107 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002108 was always usable as a hash value before this patch. That's no longer
2109 necessarily so.
2110
2111- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002112 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002113 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002114 #1454844)
2115
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002116- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2117 involving generators that have paused outside of any ``try`` or ``with``
2118 blocks. (In 2.5a1, a paused generator that was part of a reference
2119 cycle could not be garbage collected, regardless of whether it was
2120 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00002121
Anthony Baxter51bcb682006-04-05 14:51:42 +00002122Extension Modules
2123-----------------
2124
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00002125- Patch #1191065: Fix preprocessor problems on systems where recvfrom
2126 is a macro.
2127
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002128- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2129 fails with an error condition.
2130
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002131- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2132
2133- Bug #1117761: bsddb.*open() no longer raises an exception when using
2134 the cachesize parameter.
2135
2136- Bug #1149413: bsddb.*open() no longer raises an exception when using
2137 a temporary db (file=None) with the 'n' flag to truncate on open.
2138
2139- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2140 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002141
Armin Rigoa9017c32006-04-19 11:50:27 +00002142- Patch #1062014: AF_UNIX sockets under Linux have a special
2143 abstract namespace that is now fully supported.
2144
Anthony Baxter51bcb682006-04-05 14:51:42 +00002145Library
2146-------
2147
Peter Astrand7d1d4362006-07-14 14:04:45 +00002148- Bug #1223937: subprocess.CalledProcessError reports the exit status
2149 of the process using the returncode attribute, instead of
2150 abusing errno.
2151
Tim Peters711bf302006-04-25 03:31:36 +00002152- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2153 a doctest to be skipped (the code is not run, and the expected output
2154 or exception is ignored).
2155
Nick Coghlanda2268f2006-04-24 04:37:15 +00002156- Fixed contextlib.nested to cope with exceptions being raised and
2157 caught inside exit handlers.
2158
Greg Wardab05edc2006-04-23 03:47:58 +00002159- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2160 hex, octal, or binary; add ``append_const`` action; keep going if
2161 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2162 added ``epilog`` for better help generation).
2163
Tim Peters21fbd572006-04-21 21:18:10 +00002164- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2165 called from a thread spawned as a side effect of importing a module.
2166
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002167- The pydoc module now supports documenting packages contained in
2168 .zip or .egg files.
2169
2170- The pkgutil module now has several new utility functions, such
2171 as ``walk_packages()`` to support working with packages that are either
2172 in the filesystem or zip files.
2173
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002174- The mailbox module can now modify and delete messages from
2175 mailboxes, in addition to simply reading them. Thanks to Gregory
2176 K. Johnson for writing the code, and to the 2005 Google Summer of
2177 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002178
Tim Petersc7605f22006-04-17 21:12:33 +00002179- The ``__del__`` method of class ``local`` in module ``_threading_local``
2180 returned before accomplishing any of its intended cleanup.
2181
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002182- Patch #790710: Add breakpoint command lists in pdb.
2183
Martin v. Löwis0db2a982006-04-16 20:55:38 +00002184- Patch #1063914: Add Tkinter.Misc.clipboard_get().
2185
Martin v. Löwis4b501e62006-04-15 08:41:11 +00002186- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
2187
Anthony Baxtere29002c2006-04-12 12:07:31 +00002188- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2189 Windows. Bug #1469163.
2190
Phillip J. Eby47032112006-04-11 01:07:43 +00002191- The warnings, linecache, inspect, traceback, site, and doctest modules
2192 were updated to work correctly with modules imported from zipfiles or
2193 via other PEP 302 __loader__ objects.
2194
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002195- Patch #1467770: Reduce usage of subprocess._active to processes which
2196 the application hasn't waited on.
2197
Martin v. Löwisb04dee92006-04-10 08:34:21 +00002198- Patch #1462222: Fix Tix.Grid.
2199
Neal Norwitza31bf182006-04-09 03:35:43 +00002200- Fix exception when doing glob.glob('anything*/')
2201
Skip Montanaro262fb922006-04-21 02:31:07 +00002202- The pstats.Stats class accepts an optional stream keyword argument to
2203 direct output to an alternate file-like object.
2204
Anthony Baxter51bcb682006-04-05 14:51:42 +00002205Build
2206-----
2207
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002208- The Makefile now has a reindent target, which runs reindent.py on
2209 the library.
2210
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002211- Patch #1470875: Building Python with MS Free Compiler
2212
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002213- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002214
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002215- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2216 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002217 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002218 CXX from --with-cxx-main, see description in README.
2219
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002220- Patch #1429775: Link extension modules with the shared libpython.
2221
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002222- Fixed a libffi build problem on MIPS systems.
2223
Tim Peters8931ff12006-05-13 23:28:20 +00002224- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2225 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2226 and "%zu" for unsigned integers of type ``size_t``.
2227
Anthony Baxter51bcb682006-04-05 14:51:42 +00002228Tests
2229-----
2230
Nick Coghlanda2268f2006-04-24 04:37:15 +00002231- test_contextlib now checks contextlib.nested can cope with exceptions
2232 being raised and caught inside exit handlers.
2233
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002234- test_cmd_line now checks operation of the -m and -c command switches
2235
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002236- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2237 it separately and by hand. It also wasn't cleaning up its changes to
2238 the current Decimal context.
2239
Thomas Woutersabd08882006-04-26 15:53:30 +00002240- regrtest.py now has a -M option to run tests that test the new limits of
2241 containers, on 64-bit architectures. Running these tests is only sensible
2242 on 64-bit machines with more than two gigabytes of memory. The argument
2243 passed is the maximum amount of memory for the tests to use.
2244
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00002245Tools

2247
2248- Added the Python benchmark suite pybench to the Tools/ directory;
2249 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002251Documentation
2252-------------
2253
Tim Petersb06d28c2006-05-12 01:57:59 +00002254- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2255
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002256- PEP 343: Added Context Types section to the library reference
2257 and attempted to bring other PEP 343 related documentation into
2258 line with the implementation and/or python-dev discussions.
2259
Tim Peters8dc73d22006-04-24 02:03:16 +00002260- Bug #1337990: clarified that ``doctest`` does not support examples
2261 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002264What's New in Python 2.5 alpha 1?
2265=================================
2266
Anthony Baxterebed3f62006-04-03 15:03:44 +00002267*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002268
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002269Core and builtins
2270-----------------
2271
Nick Coghlan43832302006-04-23 17:04:07 +00002272- PEP 338: -m command line switch now delegates to runpy.run_module
2273 allowing it to support modules in packages and zipfiles
2274
Martin v. Löwisc661b882006-04-20 04:54:23 +00002275- On Windows, .DLL is not an accepted file name extension for
2276 extension modules anymore; extensions are only found if they
2277 end in .PYD.
2278
Martin v. Löwisea62d252006-04-03 10:56:49 +00002279- Bug #1421664: sys.stderr.encoding is now set to the same value as
2280 sys.stdout.encoding.
2281
Neal Norwitz92e212f2006-04-03 04:48:37 +00002282- __import__ accepts keyword arguments.
2283
Georg Brandlccadf842006-03-31 18:54:53 +00002284- Patch #1460496: round() now accepts keyword arguments.
2285
Anthony Baxter262c00a2006-03-30 10:53:17 +00002286- Fixed bug #1459029 - unicode reprs were double-escaped.
2287
Hye-Shik Changd478f342006-03-23 12:32:36 +00002288- Patch #1396919: The system scope threads are reenabled on FreeBSD
2289 5.4 and later versions.
2290
Neal Norwitze98ccf62006-03-23 05:39:47 +00002291- Bug #1115379: Compiling a Unicode string with an encoding declaration
2292 now gives a SyntaxError.
2293
Georg Brandlabd1ff82006-03-18 07:59:59 +00002294- Previously, Python code had no easy way to access the contents of a
2295 cell object. Now, a ``cell_contents`` attribute has been added
2296 (closes patch #1170323).
2297
Tim Peterscf79aac2006-03-16 01:14:46 +00002298- Patch #1123430: Python's small-object allocator now returns an arena to
2299 the system ``free()`` when all memory within an arena becomes unused
2300 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2301 freed. Some applications will see a drop in virtual memory size now,
2302 especially long-running applications that, from time to time, temporarily
2303 use a large number of small objects. Note that when Python returns an
2304 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002305 platform C library will in turn return that memory to the operating system.
2306 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002307 appears to be effective at least on Microsoft C and gcc-based systems.
2308 Thanks to Evan Jones for hard work and patience.
2309
Georg Brandl533ff6f2006-03-08 18:09:27 +00002310- Patch #1434038: property() now uses the getter's docstring if there is
2311 no "doc" argument given. This makes it possible to legitimately use
2312 property() as a decorator to produce a read-only property.
2313
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002314- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2315 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2316 of requiring an int or long in slicing and a few other contexts, enabling
2317 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2318
Neal Norwitz995acdf2006-03-07 05:01:00 +00002319- Fixed various bugs reported by Coverity's Prevent tool.
2320
Brett Cannonbf364092006-03-01 04:25:17 +00002321- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2322 new exception base class, BaseException, which has a new message attribute.
2323 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2324 Raising a string exception now raises a DeprecationWarning.
2325
Thomas Woutersfb609f42006-02-28 16:37:25 +00002326- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2327 explicitly relative, using 'from .module import name' to mean 'from the same
2328 package as this module is in. Imports without dots still default to the
2329 old relative-then-absolute, unless 'from __future__ import
2330 absolute_import' is used.
2331
Brett Cannona7446e32006-02-27 23:39:10 +00002332- Properly check if 'warnings' raises an exception (usually when a filter set
2333 to "error" is triggered) when raising a warning for raising string
2334 exceptions.
2335
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002336- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002337 The name was removed from Include/code.h.
2338
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002339- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002340
Guido van Rossum1968ad32006-02-25 22:38:04 +00002341- Patch 1433928:
2342 - The copy module now "copies" function objects (as atomic objects).
2343 - dict.__getitem__ now looks for a __missing__ hook before raising
2344 KeyError.
2345
Tim Peters84ef21c2006-02-28 20:39:06 +00002346- PEP 343: with statement implemented. Needs ``from __future__ import
2347 with_statement``. Use of 'with' as a variable will generate a warning.
2348 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002349 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002350 The following objects have __context__ methods:
2351 - The built-in file type.
2352 - The thread.LockType type.
2353 - The following types defined by the threading module:
2354 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2355 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002356
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002357- Fix the encodings package codec search function to only search
2358 inside its own package. Fixes problem reported in patch #1433198.
2359
2360 Note: Codec packages should implement and register their own
2361 codec search function. PEP 100 has the details.
2362
Tim Peters9ea89d22006-06-04 03:26:02 +00002363- PEP 353: Using ``Py_ssize_t`` as the index type.
2364
2365- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2366 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2367 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2368 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2369 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002370
Neal Norwitzfc76d632006-01-10 06:03:13 +00002371- Patch #1400181, fix unicode string formatting to not use the locale.
2372 This is how string objects work. u'%f' could use , instead of .
2373 for the decimal point. Now both strings and unicode always use periods.
2374
Neal Norwitz671b9e32006-01-09 07:07:12 +00002375- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2376 configure would break checking curses.h.
2377
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002378- Bug #959576: The pwd module is now builtin. This allows Python to be
2379 built on UNIX platforms without $HOME set.
2380
Neal Norwitzc10978f2005-12-19 06:07:16 +00002381- Bug #1072182, fix some potential problems if characters are signed.
2382
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002383- Bug #889500, fix line number on SyntaxWarning for global declarations.
2384
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002385- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2386
Neal Norwitze7214a12005-12-18 05:03:17 +00002387- Support for converting hex strings to floats no longer works.
2388 This was not portable. float('0x3') now raises a ValueError.
2389
Barry Warsaw2a38a862005-12-18 01:27:35 +00002390- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002391 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002392 is now displayed in interactive prompt banner.
2393
Georg Brandlfa166682005-12-17 21:45:17 +00002394- Implementation of PEP 341 - Unification of try/except and try/finally.
2395 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002396 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002397
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002398- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2399 now encodes backslash correctly.
2400
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002401- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2402
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002403- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002404 and long longs.
2405
Neal Norwitz67715f02005-11-09 06:59:35 +00002406- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002407 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002408 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002409
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002410- Replaced most Unicode charmap codecs with new ones using the
2411 new Unicode translate string feature in the builtin charmap
2412 codec; the codecs were created from the mapping tables available
2413 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2414 encodings now include a mapping for the Apple logo)
2415
Tim Peterse3547fd2005-12-16 23:13:57 +00002416- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002417
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002418- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002419
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002420- A new AST parser implementation was completed. The abstract
2421 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002422 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002423
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002424- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002425 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2426
Neal Norwitz708e51a2005-10-03 04:48:15 +00002427- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2428
Neal Norwitz11bd1192005-10-03 00:54:56 +00002429- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2430 Provide a warning when a directory is passed on the command line.
2431
Neal Norwitz40d37812005-10-02 01:48:49 +00002432- Fix segfault with invalid coding.
2433
2434- SF bug #772896: unknown encoding results in MemoryError.
2435
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002436- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002437 supported a __len__() method which evaluated to False when the iterator
2438 was empty.
2439
Guido van Rossum630db602005-09-20 18:49:54 +00002440- On 64-bit platforms, when __len__() returns a value that cannot be
2441 represented as a C int, raise OverflowError.
2442
Skip Montanarof8948ca2005-09-19 03:54:46 +00002443- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002444 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002445
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002446- SF bug #893549: parsing keyword arguments was broken with a few format
2447 codes.
2448
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002449- Changes donated by Elemental Security to make it work on AIX 5.3
2450 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2451 bug #105470: test_pwd fails on 64bit system (Opteron).
2452
Guido van Rossum539c6622005-09-14 17:49:54 +00002453- Changes donated by Elemental Security to make it work on HP-UX 11 on
2454 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2455
Georg Brandl4550b8d2005-08-26 06:43:52 +00002456- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002457 (fixes bug #1119418).
2458
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002459- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2460
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002461- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2462 exceptions that cause a function to exit.
2463
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002464- The implementation of set() and frozenset() was revised to use its
2465 own internal data structure. Memory consumption is reduced by 1/3
2466 and there are modest speed-ups as well. The API is unchanged.
2467
Tim Petersde7990b2005-07-17 23:45:23 +00002468- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2469
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002470- SF bug #1229429: PyObject_CallMethod failed to decrement some
2471 reference counts in some error exit cases.
2472
Tim Petersecc6e6a2005-07-10 22:30:55 +00002473- SF bug #1185883: Python's small-object memory allocator took over
2474 a block managed by the platform C library whenever a realloc specified
2475 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002476 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002477 portable way to copy data from the C-managed block into Python's
2478 small-object space without risking a memory fault. Python's small-object
2479 realloc now leaves such blocks under the control of the platform C
2480 realloc.
2481
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002482- SF bug #1232517: An overflow error was not detected properly when
2483 attempting to convert a large float to an int in os.utime().
2484
Raymond Hettinger3296e692005-06-29 23:29:56 +00002485- SF bug #1224347: hex longs now print with lowercase letters just
2486 like their int counterparts.
2487
Michael W. Hudson188d4362005-06-20 16:52:57 +00002488- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2489 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2490 interpreter states; back out that fix and do a better job (see
2491 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2492 for a longer write-up of the problem).
2493
Michael W. Hudsondf888462005-06-03 14:41:55 +00002494- SF patch #1180995: marshal now uses a binary format by default when
2495 serializing floats.
2496
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002497- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2498 the routines that promise to produce IEEE 754 binary representations
2499 of floats now simply copy bytes around.
2500
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002501- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2502 278.
2503
Brett Cannonc3647ac2005-04-26 03:45:26 +00002504- patch #1109424: int, long, float, complex, and unicode now check for the
2505 proper magic slot for type conversions when subclassed. Previously the
2506 magic slot was ignored during conversion. Semantics now match the way
2507 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002508 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002509 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002510 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002511
Barry Warsawc8d907c2005-04-19 23:43:40 +00002512- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2513 NULL, now raise an AttributeError when attempting to set or delete the
2514 attribute. Previously a TypeError was raised, but this was inconsistent
2515 with the equivalent pure-Python implementation.
2516
Michael W. Hudson774479c2005-04-18 08:46:17 +00002517- It is now safe to call PyGILState_Release() before
2518 PyEval_InitThreads() (note that if there is reason to believe there
2519 are multiple threads around you still must call PyEval_InitThreads()
2520 before using the Python API; this fix is for extension modules that
2521 have no way of knowing if Python is multi-threaded yet).
2522
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002523- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2524 disabled caused a crash.
2525
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002526- Bug #1165306: instancemethod_new allowed the creation of a method
2527 with im_class == im_self == NULL, which caused a crash when called.
2528
Tim Petersecc6e6a2005-07-10 22:30:55 +00002529- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002530 fixes the crash seen in bug #1165761
2531
Raymond Hettinger96229b12005-03-11 06:49:40 +00002532- Added two new builtins, any() and all().
2533
Brett Cannon409d8f22005-03-05 06:47:57 +00002534- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002535 (e.g., ``class C(): pass`` is no longer a syntax error).
2536 Patch #1176012 added support to the 'parser' module and 'compiler' package
2537 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002538
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002539- Patch #1115086: Support PY_LONGLONG in structmember.
2540
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002541- Bug #1155938: new style classes did not check that __init__() was
2542 returning None.
2543
Tim Petersecc6e6a2005-07-10 22:30:55 +00002544- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002545 ('\') with a specific error message.
2546
Martin v. Löwisff232d72005-03-03 09:24:38 +00002547- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2548
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002549- Bug #1124295: the __name__ attribute of file objects was
2550 inadvertently made inaccessible in restricted mode.
2551
Tim Petersecc6e6a2005-07-10 22:30:55 +00002552- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002553 an ferror() call.
2554
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002555- min() and max() now support key= arguments with the same meaning as in
2556 list.sort().
2557
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002558- The peephole optimizer now performs simple constant folding in expressions:
2559 (2+3) --> (5).
2560
Raymond Hettingera422c342005-01-11 03:03:27 +00002561- set and frozenset objects can now be marshalled. SF #1098985.
2562
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002563- Bug #1077106: Poor argument checking could cause memory corruption
2564 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002565
Jeremy Hyltonab630502005-02-04 18:44:06 +00002566- The parser did not complain about future statements in illegal
2567 positions. It once again reports a syntax error if a future
2568 statement occurs after anything other than a doc string.
2569
Neil Schemenauercf52c072005-08-12 17:34:58 +00002570- Change the %s format specifier for str objects so that it returns a
2571 unicode instance if the argument is not an instance of basestring and
2572 calling __str__ on the argument returns a unicode instance.
2573
Tim Petersf4e69282006-02-27 17:15:31 +00002574- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2575 current thread state when the auto-GIL-state machinery knows about
2576 it (since the thread state is being deleted, continuing to remember it
2577 can't help, but can hurt if another thread happens to get created with
2578 the same thread id).
2579
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002580Extension Modules
2581-----------------
2582
Georg Brandl43f08a82006-03-31 18:01:16 +00002583- Patch #1380952: fix SSL objects timing out on consecutive read()s
2584
Neal Norwitz05a45592006-03-20 06:30:08 +00002585- Patch #1309579: wait3 and wait4 were added to the posix module.
2586
Anthony Baxterfa869072006-03-20 05:21:58 +00002587- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2588 In addition, the existing ulaw code was updated.
2589
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002590- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002591 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002592

2756
Raymond Hettingerb2594052004-12-05 09:25:51 +00002757- itertools.islice() now accepts None for the start and step arguments.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002770- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2771 been renamed to have only a single underscore prefix. This was done to
2772 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002773
Nick Coghlan43832302006-04-23 17:04:07 +00002774- PEP 338: new module runpy defines a run_module function to support
2775 executing modules which provide access to source code or a code object
2776 via the PEP 302 import mechanisms.
2777
Anthony Baxter93f5b932006-04-03 08:05:07 +00002778- The email module's parsedate_tz function now sets the daylight savings

2786 in attribute values.
2787
Anthony Baxterc51ee692006-04-01 00:57:31 +00002788- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002789 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002790 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002791 module will not be built.
2792
Tim Petersc17976e2006-04-01 00:26:53 +00002793- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2794 aren't officially supported here, and trying to use them will probably
2795 raise an exception some day. But dicts have been allowed, and "mostly
2796 worked", so support for them won't go away without warning.
2797
Georg Brandl338ef7d2006-03-31 18:42:16 +00002798- Bug #1445068: getpass.getpass() can now be given an explicit stream
2799 argument to specify where to write the prompt.
2800

2816
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002817- email 4.0 package now integrated. This is largely the same as the email 3.0
2818 package that was included in Python 2.3, except that PEP 8 module names are
2819 now used (e.g. mail.message instead of email.Message). The MIME classes
2820 have been moved to a subpackage (e.g. email.mime.text instead of
2821 email.MIMEText). The old names are still supported for now. Several
2822 deprecated Message methods have been removed and lots of bugs have been
2823 fixed. More details can be found in the email package documentation.
2824
Walter Dörwald40108c92006-03-27 08:15:44 +00002825- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2826 (a subclass of tuple) that provides incremental decoders and encoders
2827 (a way to use stateful codecs without the stream API). Python functions
2828 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2829 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2830 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002832- Patch #1359365: Calling next() on a closed StringIO.String object raises
2833 a ValueError instead of a StopIteration now (like file and cString.String do).
2834 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2835 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002909 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2910 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2911 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2912 Ronald L. Rivest offered this advice for Python:
2913
2914 "The consensus of researchers in this area (at least as
2915 expressed at the NIST Hash Function Workshop 10/31/05),
2916 is that SHA-256 is a good choice for the time being, but
2917 that research should continue, and other alternatives may
2918 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002919
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002920- Added a subset of Fredrik Lundh's ElementTree package. Available

3081 be exploited in various ways.
3082
Tim Peterse3547fd2005-12-16 23:13:57 +00003083- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec

3097
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003098- Enhancements to the csv module:
3099
3100 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003101 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003102 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003103 + Dialect parameter parsing has been re-implemented to improve error
3104 reporting.
3105 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3106 dictates.
3107 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003108 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003109 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003110 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3111 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003112 + reader now allows \r characters to be quoted (previously it only allowed
3113 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003114 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003115 + Dialect classes passed to the module are no longer instantiated by
3116 the module before being parsed (the former validation scheme required
3117 this, but the mechanism was unreliable).
3118 + The dialect registry now contains instances of the internal
3119 C-coded dialect type, rather than references to python objects.
3120 + the internal c-coded dialect type is now immutable.
3121 + register_dialect now accepts the same keyword dialect specifications
3122 as the reader and writer, allowing the user to register dialects
3123 without first creating a dialect class.
3124 + a configurable limit to the size of parsed fields has been added -
3125 previously, an unmatched quote character could result in the entire
3126 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003127 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003128 the parser field size limit (returning the former limit). The initial
3129 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003130 + A line_num attribute has been added to the reader object, which tracks
3131 the number of lines read from the source iterator. This is not
3132 the same as the number of records returned, as records can span
3133 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003134 + reader and writer objects were not being registered with the cyclic-GC.
3135 This has been fixed.
3136
Brett Cannone6539c42005-01-08 02:43:53 +00003137- _DummyThread objects in the threading module now delete self.__block that is
3138 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3139 lock primitives tend to be limited in number and thus should not be wasted on
3140 a _DummyThread object. Fixes bug #1089632.
3141
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003142- The imghdr module now detects Exif files.
3143
Raymond Hettinger6065d322004-12-20 23:51:53 +00003144- StringIO.truncate() now correctly adjusts the size attribute.
3145 (Bug #951915).
3146
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003147- locale.py now uses an updated locale alias table (built using
3148 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3149 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003150 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003151
Raymond Hettinger3557f422004-12-07 12:02:02 +00003152- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3153
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003154- the pickle module no longer accepts the deprecated None option in the
3155 args tuple returned by __reduce__().
3156
Brett Cannon84667c02004-12-07 03:25:18 +00003157- optparse now optionally imports gettext. This allows its use in setup.py.
3158
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003159- the pickle module no longer uses the deprecated bin parameter.
3160
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003161- the shelve module no longer uses the deprecated binary parameter.
3162

3164
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003165- the filecmp module no longer uses the deprecated use_statcache argument.
3166
Raymond Hettinger664347b2004-12-04 21:21:53 +00003167- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3168 extended or overridden by subclasses. Formerly, the subclassed method would
3169 be ignored by the rest of the module. (Bug #1078905).
3170
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003171- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003172 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003173
Walter Dörwald36733692004-12-22 12:50:50 +00003174- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3175 once when a size argument is given. This prevents a buffer overflow in the
3176 tokenizer with very long source lines.
3177
Barry Warsaw538561e2006-01-01 21:48:54 +00003178- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3179 immediately after creating the object, without any intervening
3180 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003181
Skip Montanaro05885812005-01-16 20:48:27 +00003182- The reconvert.quote function can now emit triple-quoted strings. The
3183 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003184
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003185- ``UserString.MutableString`` now supports negative indices in
3186 ``__setitem__`` and ``__delitem__``
3187
Greg Ward40407942005-03-05 02:53:17 +00003188- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3189 correctly.
3190
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003191- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3192 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3193 character even if the user has passed a size parameter to get a proper
3194 line ending. Remove the special handling of a "\r\n" that has been split
3195 between two lines.
3196
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003197- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3198 about illegal code points. The codec now supports PEP 293 style error
3199 handlers.
3200
Walter Dörwald78a78b02005-09-01 12:04:29 +00003201- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003202 from the input stream, so that the output is a byte string in the correct
3203 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003204
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003205- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3206 considering it exactly like a '*'.
3207
Walter Dörwald007f8df2005-10-09 19:42:27 +00003208- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3209 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003210
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003211- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3212
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003213- Patch #1413711: Certain patterns of differences were making difflib
3214 touch the recursion limit.
3215
Walter Dörwald58917a62006-03-31 15:26:22 +00003216- Bug #947906: An object oriented interface has been added to the calendar
3217 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003218 called as a script (e.g. via ``python -mcalendar``). Localized month and
3219 weekday names can be ouput (even if an exotic encoding is used) using
3220 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003221

3224
Neal Norwitz602d3392006-03-31 08:21:40 +00003225- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3226 by using -mieee gcc option.
3227

3229
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003230- Build support for Win64-AMD64 was added.
3231
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003232- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3233
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003234- Patch #881820: look for openpty and forkpty also in libbsd.
3235
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003236- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3237 The zlib module is now builtin on Windows.
3238
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003239- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3240
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003241- Bug #1189330: configure did not correctly determine the necessary
3242 value of LINKCC if python was built with GCC 4.0.
3243
Trent Mick8321b422005-07-26 02:29:21 +00003244- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3245 vulnerability in zlib 1.2.1 and 1.2.2.
3246
Brett Cannon08cd5982005-04-24 22:26:38 +00003247- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3248 flags that change binary compatibility. Changes were also made to
3249 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003250 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003251
Bob Ippolitoed233462005-03-29 13:47:59 +00003252- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3253 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3254 no longer exists). This configure patch makes things right.
3255
Martin v. Löwise2713be2005-03-08 15:03:08 +00003256- Bug #1158607: Build with --disable-unicode again.
3257
Brett Cannon46d96232005-02-16 00:07:19 +00003258- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3259 defined. Discovered as a result of not being able to build on OS X.
3260
Brett Cannon516592f2004-12-07 00:42:59 +00003261- setup.py now uses the directories specified in LDFLAGS using the -L option
3262 and in CPPFLAGS using the -I option for adding library and include
3263 directories, respectively, for compiling extension modules against. This has
3264 led to the core being compiled using the values in CPPFLAGS. It also removes
3265 the need for the special-casing of both DarwinPorts and Fink for darwin since
3266 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3267 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3268 Fink, ``-I/opt/local/include`` for DarwinPorts).
3269
Brett Cannon43802422005-02-10 20:48:03 +00003270- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3271 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3272 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3273 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003275C API
3276-----
3277
Tim Petersc9d78aa2006-03-26 23:27:58 +00003278- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3279 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3280 is obtained via the ``PyObject_`` family, it must be released via the
3281 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3282 always been officially true, but when Python's small-object allocator was
3283 introduced, an attempt was made to cater to a few extension modules
3284 discovered at the time that obtained memory via ``PyObject_New`` but
3285 released it via ``PyMem_DEL``. It's years later, and if such code still
3286 exists it will fail now (probably with segfaults, but calling wrong
3287 low-level memory management functions can yield many symptoms).
3288
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003289- Added a C API for set and frozenset objects.
3290
Raymond Hettinger66517482004-12-03 11:45:13 +00003291- Removed PyRange_New().
3292
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003293- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3294 mapping argument now. This string is used as a mapping table. Byte values
3295 greater than the length of the string and 0xFFFE are treated as undefined
3296 mappings.
