Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000014
Jeffrey Yasskin478a1aa2008-12-10 07:28:12 +000015- Issue #4589: Propagated an exception thrown by a context manager's
16 __exit__ method's result while it's being converted to bool.
17
Amaury Forgeot d'Arcef633d72008-11-18 22:35:48 +000018- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
19
Benjamin Peterson42fe1a22008-11-17 23:35:24 +000020- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
21
Benjamin Peterson6f08e852008-11-03 15:19:35 +000022- Issue #4048: The parser module now correctly validates relative imports.
23
Amaury Forgeot d'Arc3b335ff2008-10-30 21:40:05 +000024- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
25 method does not return iterators for the 4th and 5th items.
26
Amaury Forgeot d'Arcb50f9922008-09-26 22:46:01 +000027- Issue #3967: Fixed a crash in the count() and find() methods of string-like
28 objects, when the "start" parameter is a huge value.
29
Benjamin Petersond1c7d072008-09-25 20:46:05 +000030- Issue #3936: The parser warnings for using "as" and "with" as variable names
31 didn't fire after import statements.
32
Amaury Forgeot d'Arcafa0d582008-09-01 20:05:08 +000033- Issue #3751: str.rpartition would perform a left-partition when called with
34 a unicode argument.

37 object was stored in the freelist.
38
Neal Norwitz4f3be8a2008-07-31 17:08:14 +000039- Apply security patches from Apple.
40
Neal Norwitz83ac0142008-07-28 05:06:20 +000041- Issue #2620: Overflow checking when allocating or reallocating memory
42 was not always being done properly in some python types and extension
43 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
44 all been updated to perform better checks and places in the code that
45 would previously leak memory on the error path when such an allocation
46 failed have been fixed.
47
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +000048- Issue #2242: Fix a crash when decoding invalid utf-7 input on certain
49 Windows / Visual Studio versions.

Mark Dickinsonab396e02008-07-16 11:04:17 +000051- Issue #3360: Fix incorrect parsing of '020000000000.0', which
52 produced a ValueError instead of giving the correct float.
53
Amaury Forgeot d'Arcceda6a62008-07-01 20:52:56 +000054- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
55 set to a custom object whose write() method happens to install
56 another file in sys.stdout.
57
Amaury Forgeot d'Arcb15bdf72008-07-01 20:59:49 +000058- Issue #3088: Corrected a race condition in classes derived from
59 threading.local: the first member set by a thread could be saved in
60 another thread's dictionary.
61
Amaury Forgeot d'Arc3255e132008-06-16 19:22:42 +000062- Issue #3100: Corrected a crash on deallocation of a subclassed weakref which
63 holds the last (strong) reference to its referent.
64
Guido van Rossumaa975432008-04-10 22:43:58 +000065- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
66 having a self-referential tuple, which is possible from C code. Nor did
67 object's tp_str consider that a type's tp_str could do something that could
68 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
69 respectively, fixed the issues. (Backport of r58288 from trunk.)
70
Georg Brandld9f1da02008-03-29 01:50:46 +000071- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
72 cannot be executed.

Amaury Forgeot d'Arc8432d862008-03-28 20:45:42 +000074- The compilation of a class nested in another class used to leak one
75 reference on the outer class name.
76
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000077- Issue #1477: With narrow Unicode builds, the unicode escape sequence
78 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
79 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
80 UTF-16 surrogates are generated in this case, like normal unicode literals
81 and the 'unicode-escape' codec.
82
Neal Norwitzb3635f92008-03-18 04:17:36 +000083- Issue #2321: use pymalloc for unicode object string data to reduce
84 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +000085
Sean Reifscheider4af861c2008-03-20 17:39:31 +000086- Issue #2238: Some syntax errors in *args and **kwargs expressions could give
87 bogus error messages.
88
Gregory P. Smith14acde32008-04-09 23:41:13 +000089- Issue #2587: In the C API, PyString_FromStringAndSize() takes a signed size
90 parameter but was not verifying that it was greater than zero. Values
91 less than zero will now raise a SystemError and return NULL to indicate a
92 bug in the calling C code.
93
Gregory P. Smith9aa040d2008-06-02 00:07:25 +000094- Issue #2588, #2589: Fix potential integer underflow and overflow
95 conditions in the PyOS_vsnprintf C API function.
96
Gregory P. Smithcae7f882008-09-07 06:44:12 +000097- Issue #1204: The configure script now tests for additional libraries
98 that may be required when linking against readline. This fixes issues
99 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
Georg Brandld9f1da02008-03-29 01:50:46 +0000100
Gregory P. Smitha7a94a02008-09-22 00:22:44 +0000101- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
102 library targets in the Makefile.

122 its symbolic link.
123
Thomas Heller275e2292008-08-19 17:17:37 +0000124- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
125 api functions without holding the GIL, which could lead to a fatal
126 error when they failed.
127
Amaury Forgeot d'Arc22679b82008-08-18 19:33:42 +0000128- Issue #2234: distutils failed for some versions of the cygwin compiler. The
129 version reported by these tools does not necessarily follow the python
130 version numbering scheme, so the module is less strict when parsing it.
131
Hirokazu Yamamoto1d63a452008-08-17 09:49:10 +0000132- Issue #2222: Fixed reference leak when occured os.rename()

154 string literals; previously, ["" ""] was rendered as [""""], which is
155 incorrect python code.
156
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +0000157- Issue #2482: Make sure that the coefficient of a Decimal is always
158 stored as a str instance, not as a unicode instance. This ensures

160 regression from Python 2.5.1 to Python 2.5.2.
161
Mark Dickinson26c25d92008-03-25 14:35:25 +0000162- Issue #2478: fix failure of decimal.Decimal(0).sqrt()

Martin v. Löwis897704d2007-06-08 17:29:40 +0000278Core and builtins
279-----------------
280
Martin v. Löwis73c01d42008-02-14 11:26:18 +0000281- Added checks for integer overflows, contributed by Google. Some are
282 only available if asserts are left in the code, in cases where they
283 can't be triggered from Python code.
284
Amaury Forgeot d'Arc3e5f8a62008-02-08 01:05:21 +0000285- Issue #2045: Fix an infinite recursion triggered when printing a subclass of
286 collections.defaultdict, if its default_factory is set to a bound method.
287
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000288- Issue #1920: "while 0" statements were completely removed by the compiler,
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000289 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000290 the condition is false. Now the compiler correctly emits bytecode for the
291 "else" suite.
292
Guido van Rossumd933e0a2008-01-24 18:28:37 +0000293- A few crashers fixed: weakref_in_del.py (issue #1377858);
294 loosing_dict_ref.py (issue #1303614, test67.py);
295 borrowed_ref_[34].py (not in tracker).
296
297- Fix for #1303614 and #1174712 backported from the trunk:
298 __dict__ descriptor abuse for subclasses of built-in types;
299 subclassing from both ModuleType and another built-in types.
300
Christian Heimesd2f4cb82008-01-23 14:20:41 +0000301- Bug #1915: Python compiles with --enable-unicode=no again. However
302 several extension methods and modules do not work without unicode
303 support.
304
Mark Dickinson2bebadf2008-01-21 21:54:47 +0000305- Issue #1678380: distinction between 0.0 and -0.0 was lost during constant

888
Georg Brandld59ea472007-03-08 18:37:35 +0000889- unittest now verifies more of its assumptions. In particular, TestCase
890 and TestSuite subclasses (not instances) are no longer accepted in
891 TestSuite.addTest(). This should cause no incompatibility since it
892 never made sense with ordinary subclasses -- the failure just occurred
893 later, with a more cumbersome exception.

Neal Norwitzff4b63b2006-08-04 04:50:21 +00001247
1248Core and builtins
1249-----------------
1250
Neal Norwitz24b6f202006-09-05 04:43:56 +00001251- Fix infinite recursion when subclassing long and overriding __hash__.
1252
1253- Fix concatenation (+=) of long strings.
1254
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001255- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001256 compared equal or unequal to a string and a UnicodeDecodeError
1257 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001258
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001259 Instead, the equal (==) and unequal (!=) comparison operators will
1260 now issue a UnicodeWarning and interpret the two objects as
1261 unequal. The UnicodeWarning can be filtered as desired using
1262 the warning framework, e.g. silenced completely, turned into an
1263 exception, logged, etc.
1264
1265 Note that compare operators other than equal and unequal will still
1266 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001267
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001268- Fix segfault when doing string formatting on subclasses of long.
1269
1270- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1271 with new-style classes.
1272
1273- Fix bug related to __len__ functions returning negative values with
1274 classic classes.
1275
1276- Patch #1538606, Fix __index__() clipping. There were some problems
1277 discovered with the API and how integers that didn't fit into Py_ssize_t
1278 were handled. This patch attempts to provide enough alternatives
1279 to effectively use __index__.
1280
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001281- Bug #1536021: __hash__ may now return long int; the final hash
1282 value is obtained by invoking hash on the long int.
1283
Thomas Hellerab1049c2006-08-08 17:37:00 +00001284- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1285
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001286- Bug #1535165: fixed a segfault in input() and raw_input() when
1287 sys.stdin is closed.
1288
Thomas Heller74d36f02006-08-04 18:17:40 +00001289- On Windows, the PyErr_Warn function is now exported from
1290 the Python dll again.
1291
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001292- Bug #1191458: tracing over for loops now produces a line event
1293 on each iteration. Fixing this problem required changing the .pyc
1294 magic number. This means that .pyc files generated before 2.5c1
1295 will be regenerated.
1296
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001297- Bug #1333982: string/number constants were inappropriately stored
1298 in the byte code and co_consts even if they were not used, ie
1299 immediately popped off the stack.
1300
Georg Brandle9462c72006-08-04 18:03:37 +00001301- Fixed a reference-counting problem in property().
1302

1304Library
1305-------
1306
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001307- Fix a bug in the ``compiler`` package that caused invalid code to be
1308 generated for generator expressions.
1309
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001310- The distutils version has been changed to 2.5.0. The change to
1311 keep it programmatically in sync with the Python version running
1312 the code (introduced in 2.5b3) has been reverted. It will continue
1313 to be maintained manually as static string literal.
1314
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001315- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001316 and this cannot be converted to the required C type, an exception is
1317 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001318 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001319
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001320- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001321 an exception.
1322
Tim Peterscbdd3502006-09-05 01:47:53 +00001323- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001324 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001325 workarounds for clocks with low resolution, to stop the code yielding
1326 duplicate UUIDs.
1327
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001328- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1329 before raising SystemExit, allowing IDLE to honor quit() and exit().
1330
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001331- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1332
Georg Brandl7a1af772006-08-14 21:55:28 +00001333- Patch #1536071: trace.py should now find the full module name of a
1334 file correctly even on Windows.
1335
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001336- logging's atexit hook now runs even if the rest of the module has
1337 already been cleaned up.
1338
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001339- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001340
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001341- Bug #1531405, format_exception no longer raises an exception if
1342 str(exception) raised an exception.
1343
Neil Schemenauer06ded092006-08-04 16:20:30 +00001344- Fix a bug in the ``compiler`` package that caused invalid code to be
1345 generated for nested functions.

Georg Brandl3335a7a2006-08-14 21:42:55 +00001355- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1356 raises the correct exceptions.
1357
Thomas Heller1ce433e2006-08-14 16:20:04 +00001358- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1359 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1360
Thomas Heller86720042006-08-14 11:17:48 +00001361- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1362 uses the _as_parameter_ attribute when objects are passed to foreign
1363 function calls. The ctypes version number was changed to 1.0.1.
1364
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001365- Bug #1530559, struct.pack raises TypeError where it used to convert.
1366 Passing float arguments to struct.pack when integers are expected
1367 now triggers a DeprecationWarning.

1417Core and builtins
1418-----------------
1419
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001420- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001421 returned a long (see PEP 353).
1422
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001423- Bug #1515471: string.replace() accepts character buffers again.
1424
Neal Norwitz07aadb12006-07-30 06:55:48 +00001425- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1426 This provides the proper warning for struct.pack().
1427 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1428
Neal Norwitz0d62a062006-07-30 06:53:31 +00001429- Patch #1531113: Fix augmented assignment with yield expressions.
1430 Also fix a SystemError when trying to assign to yield expressions.
1431
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001432- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1433 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1434 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1435 excessive filesystem operations during imports.
1436
Tim Petersbc24eee2006-07-27 01:14:53 +00001437- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1438 operations on signed longs that are formally undefined by C.
1439 Unfortunately, at least one compiler now cares about that, so complicated
1440 the code to make that compiler happy again.
1441
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001442- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1443

1445 path on Windows.
1446
Neal Norwitze1fdb322006-07-21 05:32:28 +00001447- Fix some potential crashes found with failmalloc.
1448
Neal Norwitze7563102006-07-17 01:00:16 +00001449- Fix warnings reported by Klocwork's static analysis tool.

1452 had more than 255 blank lines.
1453
Georg Brandl9dceedb2006-07-12 15:31:17 +00001454- Patch #1521179: Python now accepts the standard options ``--help`` and
1455 ``--version`` as well as ``/?`` on Windows.

Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001457- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001458 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001459 This means that .pyc files generated before 2.5b3 will be regenerated.

Tim Peters112aad32006-07-19 00:03:19 +00001461- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001462 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001463 new ``sys._current_frames()`` returns a dictionary with one entry,
1464 mapping the faux "thread id" 0 to the current frame.

1470-------
1471
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001472- Correction of patch #1455898: In the mbcs decoder, set final=False
1473 for stream decoder, but final=True for the decode function.
1474
Georg Brandl07fec3a2006-08-01 18:49:24 +00001475- os.urandom no longer masks unrelated exceptions like SystemExit or
1476 KeyboardInterrupt.
1477
Tim Peters4643c2f2006-08-10 22:45:34 +00001478- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001479 shutil.copytree on Windows
1480
Georg Brandle34ac7c2006-07-30 11:07:23 +00001481- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1482 refers to file descriptors, not file objects.
1483
Tim Peterscbdd3502006-09-05 01:47:53 +00001484- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001485 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001486 #1513611, and probably others.
1487
Georg Brandledd9b0d2006-07-29 09:33:26 +00001488- Bug #1441397: The compiler module now recognizes module and function
1489 docstrings correctly as it did in Python 2.4.
1490
Tim Peters6f681472006-07-27 23:44:37 +00001491- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1492 lost that tests are sorted by name before being run. This rarely
1493 matters for well-written tests, but can create baffling symptoms if
1494 side effects from one test to the next affect outcomes. ``DocTestFinder``
1495 has been changed to sort the list of tests it returns.
1496
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001497- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001498 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001499
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001500- Bug #978833: Really close underlying socket in _socketobject.close.
1501
Georg Brandldb232dc2006-08-20 13:15:43 +00001502- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1503 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001504
Georg Brandlcf0c1722006-07-26 07:23:32 +00001505- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1506 to recursive calls and call it with the failing package name.
1507
Martin v. Löwis0b483032006-07-25 09:53:12 +00001508- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1509
Georg Brandlc13c34c2006-07-24 14:09:56 +00001510- Patch #1515343: Fix printing of deprecated string exceptions with a
1511 value in the traceback module.
1512
Greg Ward48fae7a2006-07-23 16:05:51 +00001513- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1514
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001515- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1516
Brett Cannoncaebe222006-07-18 04:41:36 +00001517- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1518 argument tuple. For arguments where zero is illegal, the value is forced to
1519 the minimum value that is correct. This is to support an undocumented but
1520 common way people used to fill in inconsequential information in the time
1521 tuple pre-2.4.
1522
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001523- Patch #1220874: Update the binhex module for Mach-O.
1524
Barry Warsawb110bad2006-07-21 14:51:07 +00001525- The email package has improved RFC 2231 support, specifically for
1526 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1527 (name*0=<blah>) parameter continuations. This may change the types of
1528 values returned from email.message.Message.get_param() and friends.
1529 Specifically in some cases where non-encoded continuations were used,
1530 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1531 will just return the string (since non-encoded continuations don't have
1532 charset and language parts).
1533
1534 Also, whereas % values were decoded in all parameter continuations, they are
1535 now only decoded in encoded parameter parts.
1536
Ronald Oussoren3075e162006-07-25 20:28:55 +00001537- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1538
1539- Bug #1517996: IDLE now longer shows the default Tk menu when a
1540 path browser, class browser or debugger is the frontmost window on MacOS X
1541
Barry Warsaw00decd72006-07-27 23:43:15 +00001542- Patch #1520294: Support for getset and member descriptors in types.py,
1543 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1544 of an object against these built-in types and more importantly, for getting
1545 their docstrings printed in the interactive interpreter's help() function.

1549-----------------
1550
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001551- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1552 a socket operation on a socket with a timeout, the exception will be
1553 caught correctly. Previously, the exception was not caught.
1554
Thomas Heller1393d6a2006-07-28 21:43:20 +00001555- Patch #1529514: The _ctypes extension is now compiled on more
1556 openbsd target platforms.
1557
Tim Peters9cab5932006-07-28 00:30:00 +00001558- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1559 a memory leak, affecting pickles and deep copies.
1560
Tim Petersbc24eee2006-07-27 01:14:53 +00001561- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001562 Paul Eggert.
1563
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001564- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1565
Thomas Hellerce049a02006-07-14 17:51:14 +00001566- Patch #1521817: Index range checking on ctypes arrays containing
1567 exactly one element enabled again. This allows iterating over these
1568 arrays, without the need to check the array size before.
1569
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001570- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001571 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001572 /dev/null in certain cases; this is now fixed.
1573
Thomas Heller47d7a062006-07-12 08:43:47 +00001574- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1575 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001576
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001577- Because of a misspelled preprocessor symbol, ctypes was always
1578 compiled without thread support; this is now fixed.
1579
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001580- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1581 methods now allow their database parameter to be None as the
1582 sleepycat API allows.
1583
Matt Flemingec926502006-07-28 11:27:27 +00001584- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1585 bluetooth API compared with Linux and FreeBSD.
1586
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001587Tests
1588-----
1589
1590- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1591 how long the test file should take to play. Now accepts taking 2.93 secs
1592 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1593
Georg Brandl4793aa32006-07-28 18:31:39 +00001594- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1595 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1596 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001603Mac
1604---
1605
1606- PythonLauncher now works correctly when the path to the script contains
1607 characters that are treated specially by the shell (such as quotes).
1608
1609- Bug #1527397: PythonLauncher now launches scripts with the working directory
1610 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001611 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001612 expect.

1621-----------------
1622
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001623- Bug #1441486: The literal representation of -(sys.maxint - 1)
1624 again evaluates to a int object, not a long.
1625
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001626- Bug #1501934: The scope of global variables that are locally assigned
1627 using augmented assignment is now correctly determined.
1628
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001629- Bug #927248: Recursive method-wrapper objects can now safely
1630 be released.
1631
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001632- Bug #1417699: Reject locale-specific decimal point in float()
1633 and atof().
1634
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001635- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1636 omit a default "error" argument for NULL pointer. This allows
1637 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001638
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001639- Bug #1519018: 'as' is now validated properly in import statements.
1640
Neal Norwitz28746ab2006-07-09 22:14:42 +00001641- On 64 bit systems, int literals that use less than 64 bits are
1642 now ints rather than longs.
1643
Neal Norwitzed657552006-07-10 00:04:44 +00001644- Bug #1512814, Fix incorrect lineno's when code at module scope
1645 started after line 256.
1646
Tim Peters32a83612006-07-10 21:08:24 +00001647- New function ``sys._current_frames()`` returns a dict mapping thread
1648 id to topmost thread stack frame. This is for expert use, and is
1649 especially useful for debugging application deadlocks. The functionality
1650 was previously available in Fazal Majid's ``threadframe`` extension
1651 module, but it wasn't possible to do this in a wholly threadsafe way from
1652 an extension.

1661
Tim Peters32a83612006-07-10 21:08:24 +00001662- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001663 environment variable to be set in order to the SDK environment
1664 for finding the compiler, include files, etc.

1669
Thomas Woutersadd19112006-07-05 11:03:49 +00001670- string.Template() now correctly handles tuple-values. Previously,
1671 multi-value tuples would raise an exception and single-value tuples would
1672 be treated as the value they contain, instead.
1673
Martin v. Löwisede77f52006-07-03 13:01:35 +00001674- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1675 even if some data are received.
1676
Martin v. Löwis45482392006-07-03 12:28:58 +00001677- Bug #1267547: Put proper recursive setup.py call into the
1678 spec file generated by bdist_rpm.
1679
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001680- Bug #1514693: Update turtle's heading when switching between
1681 degrees and radians.
1682
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001683- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001684 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001685
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001686- Bug #1514703: Only setup canvas window in turtle when the canvas
1687 is created.
1688
Martin v. Löwis7596e832006-07-01 15:33:37 +00001689- Bug #1513223: .close() of a _socketobj now releases the underlying
1690 socket again, which then gets closed as it becomes unreferenced.
1691
Fred Drake10497c82006-06-29 02:57:48 +00001692- Bug #1504333: Make sgmllib support angle brackets in quoted
1693 attribute values.
1694
1695- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1696 sgmllib ('[' and ']' were not accepted).
1697
Georg Brandl1be63af2006-06-28 20:23:25 +00001698- Fix a bug in the turtle module's end_fill function.
1699
Brett Cannon53ab5b72006-06-22 16:49:14 +00001700- Bug #1510580: The 'warnings' module improperly required that a Warning
1701 category be either a types.ClassType and a subclass of Warning. The proper
1702 check is just that it is a subclass with Warning as the documentation states.
1703
Georg Brandlad29e632006-06-21 17:45:17 +00001704- The compiler module now correctly compiles the new try-except-finally
1705 statement (bug #1509132).
1706
Neal Norwitz60373cd2006-06-22 06:30:50 +00001707- The wsgiref package is now installed properly on Unix.
1708
Vinay Sajip28e57612006-07-01 10:45:20 +00001709- A bug was fixed in logging.config.fileConfig() which caused a crash on
1710 shutdown when fileConfig() was called multiple times.
1711
Gerhard Häring762fbd32006-07-02 17:48:30 +00001712- The sqlite3 module did cut off data from the SQLite database at the first
1713 null character before sending it to a custom converter. This has been fixed
1714 now.

1717-----------------
1718
Tim Peters112aad32006-07-19 00:03:19 +00001719- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1720 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1721 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001722
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001723- Assigning None to pointer type fields in ctypes structures possible
1724 overwrote the wrong fields, this is fixed now.
1725
1726- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1727 on non-Windows platforms.
1728
1729- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1730 integer or long, without range checking.
1731
1732- Patch #1517790: It is now possible to use custom objects in the ctypes
1733 foreign function argtypes sequence as long as they provide a from_param
1734 method, no longer is it required that the object is a ctypes type.
1735
1736- The '_ctypes' extension module now works when Python is configured
1737 with the --without-threads option.
1738
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001739- Bug #1513646: os.access on Windows now correctly determines write
1740 access, again.
1741
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001742- Bug #1512695: cPickle.loads could crash if it was interrupted with

1754
Tim Peters32a83612006-07-10 21:08:24 +00001755- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001756 Previously, the slight difference could cause compilation errors of the
1757 'zlib' module on systems with more than one version of zlib.
1758
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001759- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxterd1136802006-06-19 12:04:15 +00001788*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001789
1790Core and builtins
1791-----------------
1792
Georg Brandla56b9152006-06-19 06:35:54 +00001793- Patch #1507676: Error messages returned by invalid abstract object operations
1794 (such as iterating over an integer) have been improved and now include the
1795 type of the offending object to help with debugging.
1796
Brett Cannonea3912b2006-06-13 21:46:41 +00001797- Bug #992017: A classic class that defined a __coerce__() method that returned
1798 its arguments swapped would infinitely recurse and segfault the interpreter.
1799
Neal Norwitz909eb122006-06-12 02:13:21 +00001800- Fix the socket tests so they can be run concurrently.
1801
Neal Norwitzb9845e72006-06-12 02:11:18 +00001802- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001803 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001804
Brett Cannon22565aa2006-06-09 22:31:23 +00001805- Bug #532646: object.__call__() will continue looking for the __call__
1806 attribute on objects until one without one is found. This leads to recursion
1807 when you take a class and set its __call__ attribute to an instance of the
1808 class. Originally fixed for classic classes, but this fix is for new-style.
1809 Removes the infinite_rec_3 crasher.
1810
Georg Brandl24250812006-06-09 18:45:48 +00001811- The string and unicode methods startswith() and endswith() now accept
1812 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1813
Brett Cannonde3b0522006-06-08 17:00:45 +00001814- Buffer objects, at the C level, never used the char buffer
1815 implementation even when the char buffer for the wrapped object was
1816 explicitly requested (originally returned the read or write buffer).
1817 Now a TypeError is raised if the char buffer is not present but is
1818 requested.
1819
Georg Brandlddbaa662006-06-04 21:56:52 +00001820- Patch #1346214: Statements like "if 0: suite" are now again optimized
1821 away like they were in Python 2.4.
1822
Georg Brandlb7c8f542006-05-27 12:30:25 +00001823- Builtin exceptions are now full-blown new-style classes instead of
1824 instances pretending to be classes, which speeds up exception handling
1825 by about 80% in comparison to 2.5a2.
1826
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001827- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1828 Unicode 4.1.
1829
Georg Brandlf4ef1162006-05-26 18:03:31 +00001830- Patch #921466: sys.path_importer_cache is now used to cache valid and
1831 invalid file paths for the built-in import machinery which leads to
1832 fewer open calls on startup.
1833
Tim Peters696cf432006-05-24 21:10:40 +00001834- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1835 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1836 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1837 the number of input digits (it was and remains linear-time for bases
1838 2, 4, 8, 16 and 32).
1839
Tim Petersb713ec22006-05-23 18:45:30 +00001840- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1841 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1842 an integer close to ``sys.maxint``. This was repaired by patch
1843 #1335972, which also gives a nice speedup.
1844
Richard Jonescebbefc2006-05-23 18:28:17 +00001845- Patch #1337051: reduced size of frame objects.
1846
1847- PyErr_NewException now accepts a tuple of base classes as its
1848 "base" parameter.
1849
Richard Jones7c88dcc2006-05-23 10:37:38 +00001850- Patch #876206: function call speedup by retaining allocated frame
1851 objects.
1852
Georg Brandl7b90e162006-05-18 07:01:27 +00001853- Bug #1462152: file() now checks more thoroughly for invalid mode
1854 strings and removes a possible "U" before passing the mode to the
1855 C library function.
1856
Neal Norwitz1004a532006-05-15 07:17:23 +00001857- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1858
Neal Norwitz373f0a72006-05-15 07:04:36 +00001859- Bug #1487966: Fix SystemError with conditional expression in assignment
1860
Martin v. Löwis879768d2006-05-11 13:28:43 +00001861- WindowsError now has two error code attributes: errno, which carries
1862 the error values from errno.h, and winerror, which carries the error
1863 values from winerror.h. Previous versions put the winerror.h values
1864 (from GetLastError()) into the errno attribute.
1865
Martin v. Löwis77736712006-05-04 05:51:03 +00001866- Patch #1475845: Raise IndentationError for unexpected indent.
1867
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001868- Patch #1479181: split open() and file() from being aliases for each other.
1869
Tim Peters44bd9862006-06-01 13:49:23 +00001870- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1871 methods were always silently ignored by dictionaries when comparing keys.
1872 They are now passed through (except when using the C API function
1873 ``PyDict_GetItem()``, whose semantics did not change).
1874
1875- Bug #1456209: In some obscure cases it was possible for a class with a
1876 custom ``__eq__()`` method to confuse dict internals when class instances
1877 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1878 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001880Extension Modules
1881-----------------
1882
Trent Mick960a3f82006-06-28 20:30:41 +00001883- Bug #1295808: expat symbols should be namespaced in pyexpat
1884
1885- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1886
Brett Cannon6ee7d012006-06-08 16:23:04 +00001887- Change binascii.hexlify to accept a read-only buffer instead of only a char
1888 buffer and actually follow its documentation.
1889
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001890- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1891
Nick Coghlanc649ec52006-05-29 12:43:05 +00001892- Patch #1478788 (modified version): The functional extension module has
1893 been renamed to _functools and a functools Python wrapper module added.
1894 This provides a home for additional function related utilities that are
1895 not specifically about functional programming. See PEP 309.
1896
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001897- Patch #1493701: performance enhancements for struct module.
1898
Georg Brandl378d5922006-05-17 14:26:50 +00001899- Patch #1490224: time.altzone is now set correctly on Cygwin.
1900
Georg Brandl8d3342b2006-05-16 07:38:27 +00001901- Patch #1435422: zlib's compress and decompress objects now have a
1902 copy() method.
1903
Andrew MacIntyre92913322006-06-13 15:04:24 +00001904- Patch #1454481: thread stack size is now tunable at runtime for thread
1905 enabled builds on Windows and systems with Posix threads support.
1906
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001907- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1908 (up to the system limit of 32K characters).
1909
1910- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1911 As a result, these functions now raise WindowsError instead of OSError.
1912
Tim Peters7a822da2006-05-25 21:50:17 +00001913- ``time.clock()`` on Win64 should use the high-performance Windows
1914 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1915 Windows platforms).
1916
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001917- Calling Tk_Init twice is refused if the first call failed as that
1918 may deadlock.
1919
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001920- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1921 accept it without potentially using an uninitialized pointer.
1922
1923- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1924 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1925 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001926
Gregory P. Smith372b5832006-06-05 18:48:21 +00001927- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001928 [pybsddb project SF patch number 1466734]
1929
Gregory P. Smith372b5832006-06-05 18:48:21 +00001930- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1931 parameter is supplied. [SF pybsddb bug #1477863]
1932
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001933- bsddb: the __len__ method of a DB object has been fixed to return correct
1934 results. It could previously incorrectly return 0 in some cases.
1935 Fixes SF bug 1493322 (pybsddb bug 1184012).
1936
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001937- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1938 aborts the db transaction safely when a modifier callback fails.
1939 Fixes SF python patch/bug #1408584.
1940
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001941- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001942 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001943 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1944 database calls that would previously deadlock. [SF python bug #775414]
1945
Vinay Sajip28e57612006-07-01 10:45:20 +00001946- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001947
Walter Dörwald4994d952006-06-19 08:07:50 +00001948- Patch #1506645: add Python wrappers for the curses functions
1949 is_term_resized, resize_term and resizeterm.

1952-------
1953
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001954- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1955 functions.
1956
Martin v. Löwis3798da02006-06-17 18:44:27 +00001957- Patch #812986: Update turtle output even if not tracing.
1958
Vinay Sajip28e57612006-07-01 10:45:20 +00001959- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001960 Tkinter.BaseWidget.
1961
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001962- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1963
Martin v. Löwis337487e2006-06-17 09:15:14 +00001964- Patch #763580: Add name and value arguments to Tkinter variable
1965 classes.
1966
Georg Brandl83cc0d02006-06-14 08:50:03 +00001967- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1968 mime.types file for determining MIME types.
1969
Georg Brandl2605ca82006-06-14 06:08:31 +00001970- Bug #1339007: Shelf objects now don't raise an exception in their
1971 __del__ method when initialization failed.
1972
Martin v. Löwisd8251432006-06-14 05:21:04 +00001973- Patch #1455898: The MBCS codec now supports the incremental mode for
1974 double-byte encodings.
1975
Tim Peters43898b42006-06-14 04:09:25 +00001976- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1977 guarantee that adjacent triples in the return list always describe
1978 non-adjacent blocks. Previously, a pair of matching blocks could end
1979 up being described by multiple adjacent triples that formed a partition
1980 of the matching pair.
1981
Greg Ward0e0c9f42006-06-11 16:24:11 +00001982- Bug #1498146: fix optparse to handle Unicode strings in option help,
1983 description, and epilog.
1984
Greg Wardd1c797e2006-06-11 14:42:41 +00001985- Bug #1366250: minor optparse documentation error.
1986
Greg Ward7f547402006-06-11 00:40:49 +00001987- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1988 clarify docs.
1989
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001990- The wsgiref package has been added to the standard library.
1991
Nick Coghlan676725d2006-06-08 13:54:49 +00001992- The functions update_wrapper() and wraps() have been added to the functools
1993 module. These make it easier to copy relevant metadata from the original
1994 function when writing wrapper functions.
1995
Tim Petersd6a9eef2006-06-05 01:48:21 +00001996- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1997 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001998
Martin v. Löwis3f767792006-06-04 19:36:28 +00001999- Patch #1359618: Speed up charmap encoder by using a trie structure
2000 for lookup.
2001
Tim Petersd609b1a2006-06-02 23:22:51 +00002002- The functions in the ``pprint`` module now sort dictionaries by key
2003 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2004 if and only if its display required more than one line, although that
2005 wasn't documented. The new behavior increases predictability; e.g.,
2006 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2007
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002008- Patch #1497027: try HTTP digest auth before basic auth in urllib2
2009 (thanks for J. J. Lee).
2010
Georg Brandl2b330372006-05-28 20:23:12 +00002011- Patch #1496206: improve urllib2 handling of passwords with respect to
2012 default HTTP and HTTPS ports.
2013
George Yoshidaf3c65de2006-05-28 16:39:09 +00002014- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
2015
Bob Ippolito7298f272006-05-23 18:43:47 +00002016- Patch #1281707: speed up gzip.readline.
2017
Georg Brandlb89316f2006-05-17 15:51:16 +00002018- Patch #1180296: Two new functions were added to the locale module:
2019 format_string() to get the effect of "format % items" but locale-aware,
2020 and currency() to format a monetary number with currency sign.
2021
Georg Brandle3a25832006-05-17 14:56:04 +00002022- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2023 and several features added, such as speed and geometry control.
2024
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002025- Patch #1488881: add support for external file objects in bz2 compressed
2026 tarfiles.
2027
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002028- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2029 stdout arguments, making it possible to redirect input and output
2030 for remote debugging.
2031
2032- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2033 a couple of issues, notably handling of long file names using the
2034 GNU LONGNAME extension.
2035
2036- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2037 new flag when ``name`` is already the name of an option flag.
2038
2039- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2040 package.
2041
2042- Patch #1472854: make the rlcompleter.Completer class usable on non-
2043 UNIX platforms.
2044
2045- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
2046

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002078What's New in Python 2.5 alpha 2?
2079=================================
2080
2081*Release date: 27-APR-2006*
2082
2083Core and builtins
2084-----------------
2085
Thomas Heller1b046642006-04-18 18:51:06 +00002086- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2087 by converting these apis from macros into exported functions again:
2088
2089 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2090 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2091 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2092 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2093 PyRun_String Py_CompileString
2094
Martin v. Löwis45294a92006-04-18 06:24:08 +00002095- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2096
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002097- All uses of PyStructSequence_InitType have been changed to initialize
2098 the type objects only once, even if the interpreter is initialized
2099 multiple times.
2100
Neal Norwitz61546162006-04-14 05:20:28 +00002101- Bug #1454485, array.array('u') could crash the interpreter. This was
2102 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2103 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2104
2105- Py_UNICODE is unsigned. It was always documented as unsigned, but
2106 due to a bug had a signed value in previous versions.
2107
Tim Peters3a5e8b12006-04-11 01:44:07 +00002108- Patch #837242: ``id()`` of any Python object always gives a positive
2109 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2110 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002111 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002112 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002113
Tim Peters3a5e8b12006-04-11 01:44:07 +00002114 def __hash__(self):
2115 return id(self) # WRONG
2116
2117 because a hash result must be a (short) Python int but it was always
2118 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002119 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002120 was always usable as a hash value before this patch. That's no longer
2121 necessarily so.
2122
2123- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002124 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002125 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002126 #1454844)
2127
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002128- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2129 involving generators that have paused outside of any ``try`` or ``with``
2130 blocks. (In 2.5a1, a paused generator that was part of a reference
2131 cycle could not be garbage collected, regardless of whether it was
2132 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00002133
Anthony Baxter51bcb682006-04-05 14:51:42 +00002134Extension Modules
2135-----------------
2136
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00002137- Patch #1191065: Fix preprocessor problems on systems where recvfrom
2138 is a macro.
2139
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002140- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2141 fails with an error condition.
2142
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002143- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2144
2145- Bug #1117761: bsddb.*open() no longer raises an exception when using
2146 the cachesize parameter.
2147
2148- Bug #1149413: bsddb.*open() no longer raises an exception when using
2149 a temporary db (file=None) with the 'n' flag to truncate on open.
2150
2151- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2152 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002153
Armin Rigoa9017c32006-04-19 11:50:27 +00002154- Patch #1062014: AF_UNIX sockets under Linux have a special
2155 abstract namespace that is now fully supported.
2156
Anthony Baxter51bcb682006-04-05 14:51:42 +00002157Library
2158-------
2159
Peter Astrand7d1d4362006-07-14 14:04:45 +00002160- Bug #1223937: subprocess.CalledProcessError reports the exit status
2161 of the process using the returncode attribute, instead of
2162 abusing errno.
2163
Tim Peters711bf302006-04-25 03:31:36 +00002164- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2165 a doctest to be skipped (the code is not run, and the expected output
2166 or exception is ignored).
2167
Nick Coghlanda2268f2006-04-24 04:37:15 +00002168- Fixed contextlib.nested to cope with exceptions being raised and
2169 caught inside exit handlers.
2170
Greg Wardab05edc2006-04-23 03:47:58 +00002171- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2172 hex, octal, or binary; add ``append_const`` action; keep going if
2173 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2174 added ``epilog`` for better help generation).
2175
Tim Peters21fbd572006-04-21 21:18:10 +00002176- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2177 called from a thread spawned as a side effect of importing a module.
2178
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002179- The pydoc module now supports documenting packages contained in
2180 .zip or .egg files.
2181
2182- The pkgutil module now has several new utility functions, such
2183 as ``walk_packages()`` to support working with packages that are either
2184 in the filesystem or zip files.
2185
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002186- The mailbox module can now modify and delete messages from
2187 mailboxes, in addition to simply reading them. Thanks to Gregory
2188 K. Johnson for writing the code, and to the 2005 Google Summer of
2189 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002190
Tim Petersc7605f22006-04-17 21:12:33 +00002191- The ``__del__`` method of class ``local`` in module ``_threading_local``
2192 returned before accomplishing any of its intended cleanup.
2193
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002194- Patch #790710: Add breakpoint command lists in pdb.
2195
Martin v. Löwis0db2a982006-04-16 20:55:38 +00002196- Patch #1063914: Add Tkinter.Misc.clipboard_get().
2197
Martin v. Löwis4b501e62006-04-15 08:41:11 +00002198- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
2199
Anthony Baxtere29002c2006-04-12 12:07:31 +00002200- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2201 Windows. Bug #1469163.
2202
Phillip J. Eby47032112006-04-11 01:07:43 +00002203- The warnings, linecache, inspect, traceback, site, and doctest modules
2204 were updated to work correctly with modules imported from zipfiles or
2205 via other PEP 302 __loader__ objects.
2206
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002207- Patch #1467770: Reduce usage of subprocess._active to processes which
2208 the application hasn't waited on.
2209
Martin v. Löwisb04dee92006-04-10 08:34:21 +00002210- Patch #1462222: Fix Tix.Grid.
2211
Neal Norwitza31bf182006-04-09 03:35:43 +00002212- Fix exception when doing glob.glob('anything*/')
2213
Skip Montanaro262fb922006-04-21 02:31:07 +00002214- The pstats.Stats class accepts an optional stream keyword argument to
2215 direct output to an alternate file-like object.
2216
Anthony Baxter51bcb682006-04-05 14:51:42 +00002217Build
2218-----
2219
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002220- The Makefile now has a reindent target, which runs reindent.py on
2221 the library.
2222
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002223- Patch #1470875: Building Python with MS Free Compiler
2224
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002225- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002226
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002227- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2228 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002229 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002230 CXX from --with-cxx-main, see description in README.
2231
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002232- Patch #1429775: Link extension modules with the shared libpython.
2233
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002234- Fixed a libffi build problem on MIPS systems.
2235
Tim Peters8931ff12006-05-13 23:28:20 +00002236- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2237 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2238 and "%zu" for unsigned integers of type ``size_t``.
2239
Anthony Baxter51bcb682006-04-05 14:51:42 +00002240Tests
2241-----
2242
Nick Coghlanda2268f2006-04-24 04:37:15 +00002243- test_contextlib now checks contextlib.nested can cope with exceptions
2244 being raised and caught inside exit handlers.
2245
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002246- test_cmd_line now checks operation of the -m and -c command switches
2247
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002248- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2249 it separately and by hand. It also wasn't cleaning up its changes to
2250 the current Decimal context.
2251
Thomas Woutersabd08882006-04-26 15:53:30 +00002252- regrtest.py now has a -M option to run tests that test the new limits of
2253 containers, on 64-bit architectures. Running these tests is only sensible
2254 on 64-bit machines with more than two gigabytes of memory. The argument
2255 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002263Documentation
2264-------------
2265
Tim Petersb06d28c2006-05-12 01:57:59 +00002266- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2267
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002268- PEP 343: Added Context Types section to the library reference
2269 and attempted to bring other PEP 343 related documentation into
2270 line with the implementation and/or python-dev discussions.
2271
Tim Peters8dc73d22006-04-24 02:03:16 +00002272- Bug #1337990: clarified that ``doctest`` does not support examples
2273 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002276What's New in Python 2.5 alpha 1?
2277=================================
2278
Anthony Baxterebed3f62006-04-03 15:03:44 +00002279*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002280
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002281Core and builtins
2282-----------------
2283
Nick Coghlan43832302006-04-23 17:04:07 +00002284- PEP 338: -m command line switch now delegates to runpy.run_module
2285 allowing it to support modules in packages and zipfiles
2286
Martin v. Löwisc661b882006-04-20 04:54:23 +00002287- On Windows, .DLL is not an accepted file name extension for
2288 extension modules anymore; extensions are only found if they
2289 end in .PYD.
2290
Martin v. Löwisea62d252006-04-03 10:56:49 +00002291- Bug #1421664: sys.stderr.encoding is now set to the same value as
2292 sys.stdout.encoding.
2293
Neal Norwitz92e212f2006-04-03 04:48:37 +00002294- __import__ accepts keyword arguments.
2295
Georg Brandlccadf842006-03-31 18:54:53 +00002296- Patch #1460496: round() now accepts keyword arguments.
2297
Anthony Baxter262c00a2006-03-30 10:53:17 +00002298- Fixed bug #1459029 - unicode reprs were double-escaped.
2299
Hye-Shik Changd478f342006-03-23 12:32:36 +00002300- Patch #1396919: The system scope threads are reenabled on FreeBSD
2301 5.4 and later versions.
2302
Neal Norwitze98ccf62006-03-23 05:39:47 +00002303- Bug #1115379: Compiling a Unicode string with an encoding declaration
2304 now gives a SyntaxError.
2305
Georg Brandlabd1ff82006-03-18 07:59:59 +00002306- Previously, Python code had no easy way to access the contents of a
2307 cell object. Now, a ``cell_contents`` attribute has been added
2308 (closes patch #1170323).
2309
Tim Peterscf79aac2006-03-16 01:14:46 +00002310- Patch #1123430: Python's small-object allocator now returns an arena to
2311 the system ``free()`` when all memory within an arena becomes unused
2312 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2313 freed. Some applications will see a drop in virtual memory size now,
2314 especially long-running applications that, from time to time, temporarily
2315 use a large number of small objects. Note that when Python returns an
2316 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002317 platform C library will in turn return that memory to the operating system.
2318 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002319 appears to be effective at least on Microsoft C and gcc-based systems.
2320 Thanks to Evan Jones for hard work and patience.
2321
Georg Brandl533ff6f2006-03-08 18:09:27 +00002322- Patch #1434038: property() now uses the getter's docstring if there is
2323 no "doc" argument given. This makes it possible to legitimately use
2324 property() as a decorator to produce a read-only property.
2325
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002326- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2327 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2328 of requiring an int or long in slicing and a few other contexts, enabling
2329 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2330
Neal Norwitz995acdf2006-03-07 05:01:00 +00002331- Fixed various bugs reported by Coverity's Prevent tool.
2332
Brett Cannonbf364092006-03-01 04:25:17 +00002333- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2334 new exception base class, BaseException, which has a new message attribute.
2335 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2336 Raising a string exception now raises a DeprecationWarning.
2337
Thomas Woutersfb609f42006-02-28 16:37:25 +00002338- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2339 explicitly relative, using 'from .module import name' to mean 'from the same
2340 package as this module is in. Imports without dots still default to the
2341 old relative-then-absolute, unless 'from __future__ import
2342 absolute_import' is used.
2343
Brett Cannona7446e32006-02-27 23:39:10 +00002344- Properly check if 'warnings' raises an exception (usually when a filter set
2345 to "error" is triggered) when raising a warning for raising string
2346 exceptions.
2347
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002348- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002349 The name was removed from Include/code.h.
2350
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002351- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002352
Guido van Rossum1968ad32006-02-25 22:38:04 +00002353- Patch 1433928:
2354 - The copy module now "copies" function objects (as atomic objects).
2355 - dict.__getitem__ now looks for a __missing__ hook before raising
2356 KeyError.
2357
Tim Peters84ef21c2006-02-28 20:39:06 +00002358- PEP 343: with statement implemented. Needs ``from __future__ import
2359 with_statement``. Use of 'with' as a variable will generate a warning.
2360 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002361 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002362 The following objects have __context__ methods:
2363 - The built-in file type.
2364 - The thread.LockType type.
2365 - The following types defined by the threading module:
2366 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2367 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002368
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002369- Fix the encodings package codec search function to only search
2370 inside its own package. Fixes problem reported in patch #1433198.
2371
2372 Note: Codec packages should implement and register their own
2373 codec search function. PEP 100 has the details.
2374
Tim Peters9ea89d22006-06-04 03:26:02 +00002375- PEP 353: Using ``Py_ssize_t`` as the index type.
2376
2377- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2378 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2379 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2380 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2381 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002382
Neal Norwitzfc76d632006-01-10 06:03:13 +00002383- Patch #1400181, fix unicode string formatting to not use the locale.
2384 This is how string objects work. u'%f' could use , instead of .
2385 for the decimal point. Now both strings and unicode always use periods.
2386
Neal Norwitz671b9e32006-01-09 07:07:12 +00002387- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2388 configure would break checking curses.h.
2389
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002390- Bug #959576: The pwd module is now builtin. This allows Python to be
2391 built on UNIX platforms without $HOME set.
2392
Neal Norwitzc10978f2005-12-19 06:07:16 +00002393- Bug #1072182, fix some potential problems if characters are signed.
2394
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002395- Bug #889500, fix line number on SyntaxWarning for global declarations.
2396
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002397- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2398
Neal Norwitze7214a12005-12-18 05:03:17 +00002399- Support for converting hex strings to floats no longer works.
2400 This was not portable. float('0x3') now raises a ValueError.
2401
Barry Warsaw2a38a862005-12-18 01:27:35 +00002402- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002403 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002404 is now displayed in interactive prompt banner.
2405
Georg Brandlfa166682005-12-17 21:45:17 +00002406- Implementation of PEP 341 - Unification of try/except and try/finally.
2407 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002408 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002409
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002410- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2411 now encodes backslash correctly.
2412
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002413- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2414
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002415- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002416 and long longs.
2417
Neal Norwitz67715f02005-11-09 06:59:35 +00002418- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002419 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002420 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002421
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002422- Replaced most Unicode charmap codecs with new ones using the
2423 new Unicode translate string feature in the builtin charmap
2424 codec; the codecs were created from the mapping tables available
2425 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2426 encodings now include a mapping for the Apple logo)
2427
Tim Peterse3547fd2005-12-16 23:13:57 +00002428- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002429
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002430- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002431
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002432- A new AST parser implementation was completed. The abstract
2433 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002434 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002435
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002436- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002437 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2438
Neal Norwitz708e51a2005-10-03 04:48:15 +00002439- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2440
Neal Norwitz11bd1192005-10-03 00:54:56 +00002441- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2442 Provide a warning when a directory is passed on the command line.
2443
Neal Norwitz40d37812005-10-02 01:48:49 +00002444- Fix segfault with invalid coding.
2445
2446- SF bug #772896: unknown encoding results in MemoryError.
2447
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002448- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002449 supported a __len__() method which evaluated to False when the iterator
2450 was empty.
2451
Guido van Rossum630db602005-09-20 18:49:54 +00002452- On 64-bit platforms, when __len__() returns a value that cannot be
2453 represented as a C int, raise OverflowError.
2454
Skip Montanarof8948ca2005-09-19 03:54:46 +00002455- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002456 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002457
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002458- SF bug #893549: parsing keyword arguments was broken with a few format
2459 codes.
2460
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002461- Changes donated by Elemental Security to make it work on AIX 5.3
2462 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2463 bug #105470: test_pwd fails on 64bit system (Opteron).
2464
Guido van Rossum539c6622005-09-14 17:49:54 +00002465- Changes donated by Elemental Security to make it work on HP-UX 11 on
2466 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2467
Georg Brandl4550b8d2005-08-26 06:43:52 +00002468- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002469 (fixes bug #1119418).
2470
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002471- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2472
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002473- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2474 exceptions that cause a function to exit.
2475
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002476- The implementation of set() and frozenset() was revised to use its
2477 own internal data structure. Memory consumption is reduced by 1/3
2478 and there are modest speed-ups as well. The API is unchanged.
2479
Tim Petersde7990b2005-07-17 23:45:23 +00002480- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2481
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002482- SF bug #1229429: PyObject_CallMethod failed to decrement some
2483 reference counts in some error exit cases.
2484
Tim Petersecc6e6a2005-07-10 22:30:55 +00002485- SF bug #1185883: Python's small-object memory allocator took over
2486 a block managed by the platform C library whenever a realloc specified
2487 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002488 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002489 portable way to copy data from the C-managed block into Python's
2490 small-object space without risking a memory fault. Python's small-object
2491 realloc now leaves such blocks under the control of the platform C
2492 realloc.
2493
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002494- SF bug #1232517: An overflow error was not detected properly when
2495 attempting to convert a large float to an int in os.utime().
2496
Raymond Hettinger3296e692005-06-29 23:29:56 +00002497- SF bug #1224347: hex longs now print with lowercase letters just
2498 like their int counterparts.
2499
Michael W. Hudson188d4362005-06-20 16:52:57 +00002500- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2501 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2502 interpreter states; back out that fix and do a better job (see
2503 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2504 for a longer write-up of the problem).
2505
Michael W. Hudsondf888462005-06-03 14:41:55 +00002506- SF patch #1180995: marshal now uses a binary format by default when
2507 serializing floats.
2508
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002509- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2510 the routines that promise to produce IEEE 754 binary representations
2511 of floats now simply copy bytes around.
2512
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002513- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2514 278.
2515
Brett Cannonc3647ac2005-04-26 03:45:26 +00002516- patch #1109424: int, long, float, complex, and unicode now check for the
2517 proper magic slot for type conversions when subclassed. Previously the
2518 magic slot was ignored during conversion. Semantics now match the way
2519 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002520 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002521 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002522 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002523
Barry Warsawc8d907c2005-04-19 23:43:40 +00002524- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2525 NULL, now raise an AttributeError when attempting to set or delete the
2526 attribute. Previously a TypeError was raised, but this was inconsistent
2527 with the equivalent pure-Python implementation.
2528
Michael W. Hudson774479c2005-04-18 08:46:17 +00002529- It is now safe to call PyGILState_Release() before
2530 PyEval_InitThreads() (note that if there is reason to believe there
2531 are multiple threads around you still must call PyEval_InitThreads()
2532 before using the Python API; this fix is for extension modules that
2533 have no way of knowing if Python is multi-threaded yet).
2534
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002535- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2536 disabled caused a crash.
2537
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002538- Bug #1165306: instancemethod_new allowed the creation of a method
2539 with im_class == im_self == NULL, which caused a crash when called.
2540
Tim Petersecc6e6a2005-07-10 22:30:55 +00002541- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002542 fixes the crash seen in bug #1165761
2543
Raymond Hettinger96229b12005-03-11 06:49:40 +00002544- Added two new builtins, any() and all().
2545
Brett Cannon409d8f22005-03-05 06:47:57 +00002546- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002547 (e.g., ``class C(): pass`` is no longer a syntax error).
2548 Patch #1176012 added support to the 'parser' module and 'compiler' package
2549 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002550
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002551- Patch #1115086: Support PY_LONGLONG in structmember.
2552
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002553- Bug #1155938: new style classes did not check that __init__() was
2554 returning None.
2555
Tim Petersecc6e6a2005-07-10 22:30:55 +00002556- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002557 ('\') with a specific error message.
2558
Martin v. Löwisff232d72005-03-03 09:24:38 +00002559- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2560
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002561- Bug #1124295: the __name__ attribute of file objects was
2562 inadvertently made inaccessible in restricted mode.
2563
Tim Petersecc6e6a2005-07-10 22:30:55 +00002564- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002565 an ferror() call.
2566
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002567- min() and max() now support key= arguments with the same meaning as in
2568 list.sort().
2569
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002570- The peephole optimizer now performs simple constant folding in expressions:
2571 (2+3) --> (5).
2572
Raymond Hettingera422c342005-01-11 03:03:27 +00002573- set and frozenset objects can now be marshalled. SF #1098985.
2574
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002575- Bug #1077106: Poor argument checking could cause memory corruption
2576 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002577
Jeremy Hyltonab630502005-02-04 18:44:06 +00002578- The parser did not complain about future statements in illegal
2579 positions. It once again reports a syntax error if a future
2580 statement occurs after anything other than a doc string.
2581
Neil Schemenauercf52c072005-08-12 17:34:58 +00002582- Change the %s format specifier for str objects so that it returns a
2583 unicode instance if the argument is not an instance of basestring and
2584 calling __str__ on the argument returns a unicode instance.
2585
Tim Petersf4e69282006-02-27 17:15:31 +00002586- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2587 current thread state when the auto-GIL-state machinery knows about
2588 it (since the thread state is being deleted, continuing to remember it
2589 can't help, but can hurt if another thread happens to get created with
2590 the same thread id).
2591
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002592Extension Modules
2593-----------------
2594
Georg Brandl43f08a82006-03-31 18:01:16 +00002595- Patch #1380952: fix SSL objects timing out on consecutive read()s
2596
Neal Norwitz05a45592006-03-20 06:30:08 +00002597- Patch #1309579: wait3 and wait4 were added to the posix module.
2598
Anthony Baxterfa869072006-03-20 05:21:58 +00002599- Patch #1231053: The audioop module now supports encoding/decoding of alaw.

2768
Raymond Hettingerb2594052004-12-05 09:25:51 +00002769- itertools.islice() now accepts None for the start and step arguments.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002782- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2783 been renamed to have only a single underscore prefix. This was done to
2784 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002785
Nick Coghlan43832302006-04-23 17:04:07 +00002786- PEP 338: new module runpy defines a run_module function to support
2787 executing modules which provide access to source code or a code object
2788 via the PEP 302 import mechanisms.
2789
Anthony Baxter93f5b932006-04-03 08:05:07 +00002790- The email module's parsedate_tz function now sets the daylight savings

2798 in attribute values.
2799
Anthony Baxterc51ee692006-04-01 00:57:31 +00002800- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002801 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002802 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002803 module will not be built.
2804
Tim Petersc17976e2006-04-01 00:26:53 +00002805- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2806 aren't officially supported here, and trying to use them will probably
2807 raise an exception some day. But dicts have been allowed, and "mostly
2808 worked", so support for them won't go away without warning.
2809
Georg Brandl338ef7d2006-03-31 18:42:16 +00002810- Bug #1445068: getpass.getpass() can now be given an explicit stream
2811 argument to specify where to write the prompt.
2812

2828
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002829- email 4.0 package now integrated. This is largely the same as the email 3.0
2830 package that was included in Python 2.3, except that PEP 8 module names are
2831 now used (e.g. mail.message instead of email.Message). The MIME classes
2832 have been moved to a subpackage (e.g. email.mime.text instead of
2833 email.MIMEText). The old names are still supported for now. Several
2834 deprecated Message methods have been removed and lots of bugs have been
2835 fixed. More details can be found in the email package documentation.
2836
Walter Dörwald40108c92006-03-27 08:15:44 +00002837- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2838 (a subclass of tuple) that provides incremental decoders and encoders
2839 (a way to use stateful codecs without the stream API). Python functions
2840 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2841 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2842 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002844- Patch #1359365: Calling next() on a closed StringIO.String object raises
2845 a ValueError instead of a StopIteration now (like file and cString.String do).
2846 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2847 called before (like file and StringIO.StringIO do).

2923 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2924 Ronald L. Rivest offered this advice for Python:
2925
2926 "The consensus of researchers in this area (at least as
2927 expressed at the NIST Hash Function Workshop 10/31/05),
2928 is that SHA-256 is a good choice for the time being, but
2929 that research should continue, and other alternatives may
2930 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002931

3112 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003113 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003114 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003115 + Dialect parameter parsing has been re-implemented to improve error

3117 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3118 dictates.
3119 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003120 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003121 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003122 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3123 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003124 + reader now allows \r characters to be quoted (previously it only allowed
3125 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003126 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003127 + Dialect classes passed to the module are no longer instantiated by
3128 the module before being parsed (the former validation scheme required
3129 this, but the mechanism was unreliable).
3130 + The dialect registry now contains instances of the internal
3131 C-coded dialect type, rather than references to python objects.
3132 + the internal c-coded dialect type is now immutable.
3133 + register_dialect now accepts the same keyword dialect specifications
3134 as the reader and writer, allowing the user to register dialects
3135 without first creating a dialect class.
3136 + a configurable limit to the size of parsed fields has been added -
3137 previously, an unmatched quote character could result in the entire
3138 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003139 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003140 the parser field size limit (returning the former limit). The initial
3141 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003142 + A line_num attribute has been added to the reader object, which tracks
3143 the number of lines read from the source iterator. This is not
3144 the same as the number of records returned, as records can span
3145 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003146 + reader and writer objects were not being registered with the cyclic-GC.
3147 This has been fixed.
3148
Brett Cannone6539c42005-01-08 02:43:53 +00003149- _DummyThread objects in the threading module now delete self.__block that is
3150 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3151 lock primitives tend to be limited in number and thus should not be wasted on
3152 a _DummyThread object. Fixes bug #1089632.
3153
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003154- The imghdr module now detects Exif files.
3155
Raymond Hettinger6065d322004-12-20 23:51:53 +00003156- StringIO.truncate() now correctly adjusts the size attribute.
3157 (Bug #951915).
3158
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003159- locale.py now uses an updated locale alias table (built using
3160 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3161 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003162 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003163
Raymond Hettinger3557f422004-12-07 12:02:02 +00003164- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3165
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003166- the pickle module no longer accepts the deprecated None option in the
3167 args tuple returned by __reduce__().
3168
Brett Cannon84667c02004-12-07 03:25:18 +00003169- optparse now optionally imports gettext. This allows its use in setup.py.
3170
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003171- the pickle module no longer uses the deprecated bin parameter.
3172
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003173- the shelve module no longer uses the deprecated binary parameter.
3174

3176
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003177- the filecmp module no longer uses the deprecated use_statcache argument.
3178
Raymond Hettinger664347b2004-12-04 21:21:53 +00003179- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3180 extended or overridden by subclasses. Formerly, the subclassed method would
3181 be ignored by the rest of the module. (Bug #1078905).
3182
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003183- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003184 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003185
Walter Dörwald36733692004-12-22 12:50:50 +00003186- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3187 once when a size argument is given. This prevents a buffer overflow in the
3188 tokenizer with very long source lines.
3189
Barry Warsaw538561e2006-01-01 21:48:54 +00003190- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3191 immediately after creating the object, without any intervening
3192 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003193
Skip Montanaro05885812005-01-16 20:48:27 +00003194- The reconvert.quote function can now emit triple-quoted strings. The
3195 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003196
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003197- ``UserString.MutableString`` now supports negative indices in
3198 ``__setitem__`` and ``__delitem__``
3199
Greg Ward40407942005-03-05 02:53:17 +00003200- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3201 correctly.
3202
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003203- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3204 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3205 character even if the user has passed a size parameter to get a proper
3206 line ending. Remove the special handling of a "\r\n" that has been split
3207 between two lines.
3208
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003209- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3210 about illegal code points. The codec now supports PEP 293 style error
3211 handlers.
3212
Walter Dörwald78a78b02005-09-01 12:04:29 +00003213- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003214 from the input stream, so that the output is a byte string in the correct
3215 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003216
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003217- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3218 considering it exactly like a '*'.
3219
Walter Dörwald007f8df2005-10-09 19:42:27 +00003220- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3221 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003222
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003223- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3224
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003225- Patch #1413711: Certain patterns of differences were making difflib
3226 touch the recursion limit.
3227
Walter Dörwald58917a62006-03-31 15:26:22 +00003228- Bug #947906: An object oriented interface has been added to the calendar
3229 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003230 called as a script (e.g. via ``python -mcalendar``). Localized month and
3231 weekday names can be ouput (even if an exotic encoding is used) using
3232 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003233
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003234Build
3235-----
3236
Neal Norwitz602d3392006-03-31 08:21:40 +00003237- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3238 by using -mieee gcc option.
3239
Martin v. Löwis86d66262006-02-17 08:40:11 +00003240- Patch #1432345: Make python compile on DragonFly.
3241
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003242- Build support for Win64-AMD64 was added.
3243
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003244- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3245
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003246- Patch #881820: look for openpty and forkpty also in libbsd.
3247
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003248- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3249 The zlib module is now builtin on Windows.
3250
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003251- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3252
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003253- Bug #1189330: configure did not correctly determine the necessary
3254 value of LINKCC if python was built with GCC 4.0.
3255
Trent Mick8321b422005-07-26 02:29:21 +00003256- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3257 vulnerability in zlib 1.2.1 and 1.2.2.
3258
Brett Cannon08cd5982005-04-24 22:26:38 +00003259- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3260 flags that change binary compatibility. Changes were also made to
3261 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003262 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003263
Bob Ippolitoed233462005-03-29 13:47:59 +00003264- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3265 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3266 no longer exists). This configure patch makes things right.
3267
Martin v. Löwise2713be2005-03-08 15:03:08 +00003268- Bug #1158607: Build with --disable-unicode again.
3269
Brett Cannon46d96232005-02-16 00:07:19 +00003270- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3271 defined. Discovered as a result of not being able to build on OS X.
3272
Brett Cannon516592f2004-12-07 00:42:59 +00003273- setup.py now uses the directories specified in LDFLAGS using the -L option
3274 and in CPPFLAGS using the -I option for adding library and include
3275 directories, respectively, for compiling extension modules against. This has
3276 led to the core being compiled using the values in CPPFLAGS. It also removes
3277 the need for the special-casing of both DarwinPorts and Fink for darwin since
3278 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3279 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3280 Fink, ``-I/opt/local/include`` for DarwinPorts).
3281
Brett Cannon43802422005-02-10 20:48:03 +00003282- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3283 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3284 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3285 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003287C API
3288-----
3289
Tim Petersc9d78aa2006-03-26 23:27:58 +00003290- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3291 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3292 is obtained via the ``PyObject_`` family, it must be released via the
3293 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3294 always been officially true, but when Python's small-object allocator was
3295 introduced, an attempt was made to cater to a few extension modules
3296 discovered at the time that obtained memory via ``PyObject_New`` but
3297 released it via ``PyMem_DEL``. It's years later, and if such code still
3298 exists it will fail now (probably with segfaults, but calling wrong
3299 low-level memory management functions can yield many symptoms).
3300
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003301- Added a C API for set and frozenset objects.
3302

3304
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003305- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3306 mapping argument now. This string is used as a mapping table. Byte values
3307 greater than the length of the string and 0xFFFE are treated as undefined
3308 mappings.
