13-----------------
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.

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.

125
Thomas Heller275e2292008-08-19 17:17:37 +0000126- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python

128 error when they failed.
129
Amaury Forgeot d'Arc22679b82008-08-18 19:33:42 +0000130- Issue #2234: distutils failed for some versions of the cygwin compiler. The
131 version reported by these tools does not necessarily follow the python
132 version numbering scheme, so the module is less strict when parsing it.
133
Hirokazu Yamamoto1d63a452008-08-17 09:49:10 +0000134- Issue #2222: Fixed reference leak when occured os.rename()

154
Amaury Forgeot d'Arc198e3532008-03-27 23:41:59 +0000155- Issue #2495: tokenize.untokenize now inserts a space between two consecutive

Mark Dickinsonbfdbfd42008-03-25 18:58:13 +0000159- Issue #2482: Make sure that the coefficient of a Decimal is always
160 stored as a str instance, not as a unicode instance. This ensures

162 regression from Python 2.5.1 to Python 2.5.2.
163

Martin v. Löwis897704d2007-06-08 17:29:40 +0000280Core and builtins
281-----------------
282
Martin v. Löwis73c01d42008-02-14 11:26:18 +0000283- Added checks for integer overflows, contributed by Google. Some are
284 only available if asserts are left in the code, in cases where they
285 can't be triggered from Python code.
286
Amaury Forgeot d'Arc3e5f8a62008-02-08 01:05:21 +0000287- Issue #2045: Fix an infinite recursion triggered when printing a subclass of
288 collections.defaultdict, if its default_factory is set to a bound method.
289
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000290- Issue #1920: "while 0" statements were completely removed by the compiler,
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000291 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000292 the condition is false. Now the compiler correctly emits bytecode for the
293 "else" suite.
294
Guido van Rossumd933e0a2008-01-24 18:28:37 +0000295- A few crashers fixed: weakref_in_del.py (issue #1377858);
296 loosing_dict_ref.py (issue #1303614, test67.py);
297 borrowed_ref_[34].py (not in tracker).
298
299- Fix for #1303614 and #1174712 backported from the trunk:
300 __dict__ descriptor abuse for subclasses of built-in types;
301 subclassing from both ModuleType and another built-in types.
302
Christian Heimesd2f4cb82008-01-23 14:20:41 +0000303- Bug #1915: Python compiles with --enable-unicode=no again. However
304 several extension methods and modules do not work without unicode

878 be equal to calling getsockname() on the server's socket. Fixed by patch
879 #1545011.
880
Thomas Heller8bf469d2007-03-09 20:48:57 +0000881- Bug #1651235: When a tuple was passed to a ctypes function call,

890
Georg Brandld59ea472007-03-08 18:37:35 +0000891- unittest now verifies more of its assumptions. In particular, TestCase
892 and TestSuite subclasses (not instances) are no longer accepted in

894 never made sense with ordinary subclasses -- the failure just occurred
895 later, with a more cumbersome exception.

Brett Cannon19d76c52006-09-09 07:18:44 +00001114- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

1250Core and builtins
1251-----------------
1252
Neal Norwitz24b6f202006-09-05 04:43:56 +00001253- Fix infinite recursion when subclassing long and overriding __hash__.
1254
1255- Fix concatenation (+=) of long strings.
1256
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001257- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001258 compared equal or unequal to a string and a UnicodeDecodeError
1259 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001260
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001261 Instead, the equal (==) and unequal (!=) comparison operators will
1262 now issue a UnicodeWarning and interpret the two objects as
1263 unequal. The UnicodeWarning can be filtered as desired using
1264 the warning framework, e.g. silenced completely, turned into an
1265 exception, logged, etc.
1266
1267 Note that compare operators other than equal and unequal will still
1268 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001269
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001270- Fix segfault when doing string formatting on subclasses of long.
1271
1272- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1273 with new-style classes.
1274
1275- Fix bug related to __len__ functions returning negative values with
1276 classic classes.
1277
1278- Patch #1538606, Fix __index__() clipping. There were some problems
1279 discovered with the API and how integers that didn't fit into Py_ssize_t
1280 were handled. This patch attempts to provide enough alternatives
1281 to effectively use __index__.
1282
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001283- Bug #1536021: __hash__ may now return long int; the final hash
1284 value is obtained by invoking hash on the long int.
1285
Thomas Hellerab1049c2006-08-08 17:37:00 +00001286- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1287
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001288- Bug #1535165: fixed a segfault in input() and raw_input() when
1289 sys.stdin is closed.
1290
Thomas Heller74d36f02006-08-04 18:17:40 +00001291- On Windows, the PyErr_Warn function is now exported from
1292 the Python dll again.
1293
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001294- Bug #1191458: tracing over for loops now produces a line event
1295 on each iteration. Fixing this problem required changing the .pyc
1296 magic number. This means that .pyc files generated before 2.5c1
1297 will be regenerated.
1298
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001299- Bug #1333982: string/number constants were inappropriately stored
1300 in the byte code and co_consts even if they were not used, ie
1301 immediately popped off the stack.
1302
Georg Brandle9462c72006-08-04 18:03:37 +00001303- Fixed a reference-counting problem in property().

1306Library
1307-------
1308
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001309- Fix a bug in the ``compiler`` package that caused invalid code to be
1310 generated for generator expressions.
1311
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001312- The distutils version has been changed to 2.5.0. The change to
1313 keep it programmatically in sync with the Python version running
1314 the code (introduced in 2.5b3) has been reverted. It will continue
1315 to be maintained manually as static string literal.
1316
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001317- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001318 and this cannot be converted to the required C type, an exception is
1319 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001320 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001321
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001322- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001323 an exception.
1324
Tim Peterscbdd3502006-09-05 01:47:53 +00001325- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001326 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001327 workarounds for clocks with low resolution, to stop the code yielding
1328 duplicate UUIDs.
1329
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001330- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1331 before raising SystemExit, allowing IDLE to honor quit() and exit().
1332
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001333- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1334
Georg Brandl7a1af772006-08-14 21:55:28 +00001335- Patch #1536071: trace.py should now find the full module name of a
1336 file correctly even on Windows.
1337
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001338- logging's atexit hook now runs even if the rest of the module has
1339 already been cleaned up.
1340
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001341- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001342
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001343- Bug #1531405, format_exception no longer raises an exception if
1344 str(exception) raised an exception.
1345
Neil Schemenauer06ded092006-08-04 16:20:30 +00001346- Fix a bug in the ``compiler`` package that caused invalid code to be
1347 generated for nested functions.

1358 raises the correct exceptions.
1359
Thomas Heller1ce433e2006-08-14 16:20:04 +00001360- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1361 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1362
Thomas Heller86720042006-08-14 11:17:48 +00001363- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1364 uses the _as_parameter_ attribute when objects are passed to foreign
1365 function calls. The ctypes version number was changed to 1.0.1.
1366
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001367- Bug #1530559, struct.pack raises TypeError where it used to convert.
1368 Passing float arguments to struct.pack when integers are expected
1369 now triggers a DeprecationWarning.

1419Core and builtins
1420-----------------
1421
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001422- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001423 returned a long (see PEP 353).
1424
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001425- Bug #1515471: string.replace() accepts character buffers again.
1426
Neal Norwitz07aadb12006-07-30 06:55:48 +00001427- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1428 This provides the proper warning for struct.pack().
1429 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1430
Neal Norwitz0d62a062006-07-30 06:53:31 +00001431- Patch #1531113: Fix augmented assignment with yield expressions.
1432 Also fix a SystemError when trying to assign to yield expressions.
1433
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001434- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1435 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1436 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1437 excessive filesystem operations during imports.
1438
Tim Petersbc24eee2006-07-27 01:14:53 +00001439- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1440 operations on signed longs that are formally undefined by C.
1441 Unfortunately, at least one compiler now cares about that, so complicated
1442 the code to make that compiler happy again.
1443
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001444- Bug #1524310: Properly report errors from FindNextFile in os.listdir.

Georg Brandl9dceedb2006-07-12 15:31:17 +00001456- Patch #1521179: Python now accepts the standard options ``--help`` and
1457 ``--version`` as well as ``/?`` on Windows.
1458
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001459- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001460 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001461 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001462
Tim Peters112aad32006-07-19 00:03:19 +00001463- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001464 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001465 new ``sys._current_frames()`` returns a dictionary with one entry,
1466 mapping the faux "thread id" 0 to the current frame.
1467
Ronald Oussoren3075e162006-07-25 20:28:55 +00001468- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

1472-------
1473
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001474- Correction of patch #1455898: In the mbcs decoder, set final=False
1475 for stream decoder, but final=True for the decode function.
1476
Georg Brandl07fec3a2006-08-01 18:49:24 +00001477- os.urandom no longer masks unrelated exceptions like SystemExit or
1478 KeyboardInterrupt.
1479
Tim Peters4643c2f2006-08-10 22:45:34 +00001480- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001481 shutil.copytree on Windows
1482
Georg Brandle34ac7c2006-07-30 11:07:23 +00001483- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1484 refers to file descriptors, not file objects.
1485
Tim Peterscbdd3502006-09-05 01:47:53 +00001486- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001487 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001488 #1513611, and probably others.
1489
Georg Brandledd9b0d2006-07-29 09:33:26 +00001490- Bug #1441397: The compiler module now recognizes module and function
1491 docstrings correctly as it did in Python 2.4.
1492
Tim Peters6f681472006-07-27 23:44:37 +00001493- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1494 lost that tests are sorted by name before being run. This rarely
1495 matters for well-written tests, but can create baffling symptoms if
1496 side effects from one test to the next affect outcomes. ``DocTestFinder``
1497 has been changed to sort the list of tests it returns.
1498
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001499- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001500 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001501
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001502- Bug #978833: Really close underlying socket in _socketobject.close.
1503
Georg Brandldb232dc2006-08-20 13:15:43 +00001504- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1505 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001506
Georg Brandlcf0c1722006-07-26 07:23:32 +00001507- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1508 to recursive calls and call it with the failing package name.
1509
Martin v. Löwis0b483032006-07-25 09:53:12 +00001510- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1511
Georg Brandlc13c34c2006-07-24 14:09:56 +00001512- Patch #1515343: Fix printing of deprecated string exceptions with a
1513 value in the traceback module.
1514
Greg Ward48fae7a2006-07-23 16:05:51 +00001515- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1516
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001517- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1518
Brett Cannoncaebe222006-07-18 04:41:36 +00001519- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1520 argument tuple. For arguments where zero is illegal, the value is forced to
1521 the minimum value that is correct. This is to support an undocumented but
1522 common way people used to fill in inconsequential information in the time
1523 tuple pre-2.4.
1524
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001525- Patch #1220874: Update the binhex module for Mach-O.
1526
Barry Warsawb110bad2006-07-21 14:51:07 +00001527- The email package has improved RFC 2231 support, specifically for
1528 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1529 (name*0=<blah>) parameter continuations. This may change the types of
1530 values returned from email.message.Message.get_param() and friends.
1531 Specifically in some cases where non-encoded continuations were used,
1532 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1533 will just return the string (since non-encoded continuations don't have
1534 charset and language parts).
1535
1536 Also, whereas % values were decoded in all parameter continuations, they are
1537 now only decoded in encoded parameter parts.
1538
Ronald Oussoren3075e162006-07-25 20:28:55 +00001539- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1540
1541- Bug #1517996: IDLE now longer shows the default Tk menu when a
1542 path browser, class browser or debugger is the frontmost window on MacOS X
1543
Barry Warsaw00decd72006-07-27 23:43:15 +00001544- Patch #1520294: Support for getset and member descriptors in types.py,
1545 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1546 of an object against these built-in types and more importantly, for getting
1547 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001550Extension Modules
1551-----------------
1552
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001553- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1554 a socket operation on a socket with a timeout, the exception will be
1555 caught correctly. Previously, the exception was not caught.
1556
Thomas Heller1393d6a2006-07-28 21:43:20 +00001557- Patch #1529514: The _ctypes extension is now compiled on more
1558 openbsd target platforms.
1559
Tim Peters9cab5932006-07-28 00:30:00 +00001560- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1561 a memory leak, affecting pickles and deep copies.
1562
Tim Petersbc24eee2006-07-27 01:14:53 +00001563- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001564 Paul Eggert.
1565
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001566- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1567
Thomas Hellerce049a02006-07-14 17:51:14 +00001568- Patch #1521817: Index range checking on ctypes arrays containing
1569 exactly one element enabled again. This allows iterating over these
1570 arrays, without the need to check the array size before.
1571
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001572- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001573 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001574 /dev/null in certain cases; this is now fixed.
1575
Thomas Heller47d7a062006-07-12 08:43:47 +00001576- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1577 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001578
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001579- Because of a misspelled preprocessor symbol, ctypes was always
1580 compiled without thread support; this is now fixed.
1581
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001582- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1583 methods now allow their database parameter to be None as the
1584 sleepycat API allows.
1585
Matt Flemingec926502006-07-28 11:27:27 +00001586- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1587 bluetooth API compared with Linux and FreeBSD.
1588
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001589Tests
1590-----
1591
1592- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1593 how long the test file should take to play. Now accepts taking 2.93 secs
1594 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1595
Georg Brandl4793aa32006-07-28 18:31:39 +00001596- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1597 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1598 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001605Mac
1606---
1607
1608- PythonLauncher now works correctly when the path to the script contains
1609 characters that are treated specially by the shell (such as quotes).
1610
1611- Bug #1527397: PythonLauncher now launches scripts with the working directory
1612 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001613 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001614 expect.

1623-----------------
1624
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001625- Bug #1441486: The literal representation of -(sys.maxint - 1)
1626 again evaluates to a int object, not a long.
1627
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001628- Bug #1501934: The scope of global variables that are locally assigned
1629 using augmented assignment is now correctly determined.
1630
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001631- Bug #927248: Recursive method-wrapper objects can now safely
1632 be released.
1633
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001634- Bug #1417699: Reject locale-specific decimal point in float()
1635 and atof().
1636
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001637- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1638 omit a default "error" argument for NULL pointer. This allows
1639 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001640
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001641- Bug #1519018: 'as' is now validated properly in import statements.
1642
Neal Norwitz28746ab2006-07-09 22:14:42 +00001643- On 64 bit systems, int literals that use less than 64 bits are
1644 now ints rather than longs.
1645
Neal Norwitzed657552006-07-10 00:04:44 +00001646- Bug #1512814, Fix incorrect lineno's when code at module scope
1647 started after line 256.
1648
Tim Peters32a83612006-07-10 21:08:24 +00001649- New function ``sys._current_frames()`` returns a dict mapping thread
1650 id to topmost thread stack frame. This is for expert use, and is
1651 especially useful for debugging application deadlocks. The functionality
1652 was previously available in Fazal Majid's ``threadframe`` extension
1653 module, but it wasn't possible to do this in a wholly threadsafe way from
1654 an extension.

1663
Tim Peters32a83612006-07-10 21:08:24 +00001664- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001665 environment variable to be set in order to the SDK environment
1666 for finding the compiler, include files, etc.

Nick Coghlan2d792252006-07-06 13:47:18 +00001670- warnings.py now ignores ImportWarning by default
1671
Thomas Woutersadd19112006-07-05 11:03:49 +00001672- string.Template() now correctly handles tuple-values. Previously,
1673 multi-value tuples would raise an exception and single-value tuples would
1674 be treated as the value they contain, instead.
1675
Martin v. Löwisede77f52006-07-03 13:01:35 +00001676- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1677 even if some data are received.
1678
Martin v. Löwis45482392006-07-03 12:28:58 +00001679- Bug #1267547: Put proper recursive setup.py call into the
1680 spec file generated by bdist_rpm.
1681
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001682- Bug #1514693: Update turtle's heading when switching between
1683 degrees and radians.
1684
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001685- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001686 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001687
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001688- Bug #1514703: Only setup canvas window in turtle when the canvas
1689 is created.
1690
Martin v. Löwis7596e832006-07-01 15:33:37 +00001691- Bug #1513223: .close() of a _socketobj now releases the underlying
1692 socket again, which then gets closed as it becomes unreferenced.
1693
Fred Drake10497c82006-06-29 02:57:48 +00001694- Bug #1504333: Make sgmllib support angle brackets in quoted
1695 attribute values.
1696
1697- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1698 sgmllib ('[' and ']' were not accepted).
1699
Georg Brandl1be63af2006-06-28 20:23:25 +00001700- Fix a bug in the turtle module's end_fill function.
1701
Brett Cannon53ab5b72006-06-22 16:49:14 +00001702- Bug #1510580: The 'warnings' module improperly required that a Warning
1703 category be either a types.ClassType and a subclass of Warning. The proper
1704 check is just that it is a subclass with Warning as the documentation states.
1705
Georg Brandlad29e632006-06-21 17:45:17 +00001706- The compiler module now correctly compiles the new try-except-finally
1707 statement (bug #1509132).
1708
Neal Norwitz60373cd2006-06-22 06:30:50 +00001709- The wsgiref package is now installed properly on Unix.
1710
Vinay Sajip28e57612006-07-01 10:45:20 +00001711- A bug was fixed in logging.config.fileConfig() which caused a crash on
1712 shutdown when fileConfig() was called multiple times.
1713
Gerhard Häring762fbd32006-07-02 17:48:30 +00001714- The sqlite3 module did cut off data from the SQLite database at the first
1715 null character before sending it to a custom converter. This has been fixed
1716 now.

1719-----------------
1720
Tim Peters112aad32006-07-19 00:03:19 +00001721- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1722 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1723 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001724
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001725- Assigning None to pointer type fields in ctypes structures possible
1726 overwrote the wrong fields, this is fixed now.
1727
1728- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1729 on non-Windows platforms.
1730
1731- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1732 integer or long, without range checking.
1733
1734- Patch #1517790: It is now possible to use custom objects in the ctypes
1735 foreign function argtypes sequence as long as they provide a from_param
1736 method, no longer is it required that the object is a ctypes type.
1737
1738- The '_ctypes' extension module now works when Python is configured
1739 with the --without-threads option.
1740
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001741- Bug #1513646: os.access on Windows now correctly determines write
1742 access, again.
1743
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001744- Bug #1512695: cPickle.loads could crash if it was interrupted with
1745 a KeyboardInterrupt.
1746
Neal Norwitza12aa882006-07-06 06:45:08 +00001747- Bug #1296433: parsing XML with a non-default encoding and
1748 a CharacterDataHandler could crash the interpreter in pyexpat.

1756
Tim Peters32a83612006-07-10 21:08:24 +00001757- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001758 Previously, the slight difference could cause compilation errors of the
1759 'zlib' module on systems with more than one version of zlib.
1760
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001761- The MSI compileall step was fixed to also support a TARGETDIR

Nick Coghlanc649ec52006-05-29 12:43:05 +00001787What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001788================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001789
Anthony Baxterd1136802006-06-19 12:04:15 +00001790*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001791
1792Core and builtins
1793-----------------
1794
Georg Brandla56b9152006-06-19 06:35:54 +00001795- Patch #1507676: Error messages returned by invalid abstract object operations
1796 (such as iterating over an integer) have been improved and now include the
1797 type of the offending object to help with debugging.
1798
Brett Cannonea3912b2006-06-13 21:46:41 +00001799- Bug #992017: A classic class that defined a __coerce__() method that returned
1800 its arguments swapped would infinitely recurse and segfault the interpreter.
1801
Neal Norwitz909eb122006-06-12 02:13:21 +00001802- Fix the socket tests so they can be run concurrently.
1803
Neal Norwitzb9845e72006-06-12 02:11:18 +00001804- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001805 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001806
Brett Cannon22565aa2006-06-09 22:31:23 +00001807- Bug #532646: object.__call__() will continue looking for the __call__
1808 attribute on objects until one without one is found. This leads to recursion
1809 when you take a class and set its __call__ attribute to an instance of the
1810 class. Originally fixed for classic classes, but this fix is for new-style.
1811 Removes the infinite_rec_3 crasher.
1812
Georg Brandl24250812006-06-09 18:45:48 +00001813- The string and unicode methods startswith() and endswith() now accept
1814 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1815
Brett Cannonde3b0522006-06-08 17:00:45 +00001816- Buffer objects, at the C level, never used the char buffer
1817 implementation even when the char buffer for the wrapped object was
1818 explicitly requested (originally returned the read or write buffer).
1819 Now a TypeError is raised if the char buffer is not present but is
1820 requested.
1821
Georg Brandlddbaa662006-06-04 21:56:52 +00001822- Patch #1346214: Statements like "if 0: suite" are now again optimized
1823 away like they were in Python 2.4.
1824
Georg Brandlb7c8f542006-05-27 12:30:25 +00001825- Builtin exceptions are now full-blown new-style classes instead of
1826 instances pretending to be classes, which speeds up exception handling
1827 by about 80% in comparison to 2.5a2.
1828
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001829- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1830 Unicode 4.1.
1831
Georg Brandlf4ef1162006-05-26 18:03:31 +00001832- Patch #921466: sys.path_importer_cache is now used to cache valid and
1833 invalid file paths for the built-in import machinery which leads to
1834 fewer open calls on startup.
1835
Tim Peters696cf432006-05-24 21:10:40 +00001836- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1837 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1838 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1839 the number of input digits (it was and remains linear-time for bases
1840 2, 4, 8, 16 and 32).
1841
Tim Petersb713ec22006-05-23 18:45:30 +00001842- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1843 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1844 an integer close to ``sys.maxint``. This was repaired by patch
1845 #1335972, which also gives a nice speedup.
1846
Richard Jonescebbefc2006-05-23 18:28:17 +00001847- Patch #1337051: reduced size of frame objects.
1848
1849- PyErr_NewException now accepts a tuple of base classes as its
1850 "base" parameter.
1851
Richard Jones7c88dcc2006-05-23 10:37:38 +00001852- Patch #876206: function call speedup by retaining allocated frame
1853 objects.
1854
Georg Brandl7b90e162006-05-18 07:01:27 +00001855- Bug #1462152: file() now checks more thoroughly for invalid mode
1856 strings and removes a possible "U" before passing the mode to the
1857 C library function.
1858
Neal Norwitz1004a532006-05-15 07:17:23 +00001859- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1860
Neal Norwitz373f0a72006-05-15 07:04:36 +00001861- Bug #1487966: Fix SystemError with conditional expression in assignment
1862
Martin v. Löwis879768d2006-05-11 13:28:43 +00001863- WindowsError now has two error code attributes: errno, which carries
1864 the error values from errno.h, and winerror, which carries the error
1865 values from winerror.h. Previous versions put the winerror.h values
1866 (from GetLastError()) into the errno attribute.
1867
Martin v. Löwis77736712006-05-04 05:51:03 +00001868- Patch #1475845: Raise IndentationError for unexpected indent.
1869
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001870- Patch #1479181: split open() and file() from being aliases for each other.
1871
Tim Peters44bd9862006-06-01 13:49:23 +00001872- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1873 methods were always silently ignored by dictionaries when comparing keys.
1874 They are now passed through (except when using the C API function
1875 ``PyDict_GetItem()``, whose semantics did not change).
1876
1877- Bug #1456209: In some obscure cases it was possible for a class with a
1878 custom ``__eq__()`` method to confuse dict internals when class instances
1879 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1880 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001882Extension Modules
1883-----------------
1884
Trent Mick960a3f82006-06-28 20:30:41 +00001885- Bug #1295808: expat symbols should be namespaced in pyexpat
1886
1887- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1888
Brett Cannon6ee7d012006-06-08 16:23:04 +00001889- Change binascii.hexlify to accept a read-only buffer instead of only a char
1890 buffer and actually follow its documentation.
1891
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001892- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1893
Nick Coghlanc649ec52006-05-29 12:43:05 +00001894- Patch #1478788 (modified version): The functional extension module has
1895 been renamed to _functools and a functools Python wrapper module added.
1896 This provides a home for additional function related utilities that are
1897 not specifically about functional programming. See PEP 309.
1898
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001899- Patch #1493701: performance enhancements for struct module.
1900
Georg Brandl378d5922006-05-17 14:26:50 +00001901- Patch #1490224: time.altzone is now set correctly on Cygwin.
1902
Georg Brandl8d3342b2006-05-16 07:38:27 +00001903- Patch #1435422: zlib's compress and decompress objects now have a
1904 copy() method.
1905
Andrew MacIntyre92913322006-06-13 15:04:24 +00001906- Patch #1454481: thread stack size is now tunable at runtime for thread
1907 enabled builds on Windows and systems with Posix threads support.
1908
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001909- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1910 (up to the system limit of 32K characters).
1911
1912- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1913 As a result, these functions now raise WindowsError instead of OSError.
1914
Tim Peters7a822da2006-05-25 21:50:17 +00001915- ``time.clock()`` on Win64 should use the high-performance Windows
1916 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1917 Windows platforms).
1918
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001919- Calling Tk_Init twice is refused if the first call failed as that
1920 may deadlock.
1921
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001922- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1923 accept it without potentially using an uninitialized pointer.
1924
1925- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1926 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1927 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001928
Gregory P. Smith372b5832006-06-05 18:48:21 +00001929- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001930 [pybsddb project SF patch number 1466734]
1931
Gregory P. Smith372b5832006-06-05 18:48:21 +00001932- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1933 parameter is supplied. [SF pybsddb bug #1477863]
1934
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001935- bsddb: the __len__ method of a DB object has been fixed to return correct
1936 results. It could previously incorrectly return 0 in some cases.
1937 Fixes SF bug 1493322 (pybsddb bug 1184012).
1938
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001939- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1940 aborts the db transaction safely when a modifier callback fails.
1941 Fixes SF python patch/bug #1408584.
1942
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001943- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001944 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001945 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1946 database calls that would previously deadlock. [SF python bug #775414]
1947
Vinay Sajip28e57612006-07-01 10:45:20 +00001948- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1954-------
1955
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001956- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1957 functions.
1958
Martin v. Löwis3798da02006-06-17 18:44:27 +00001959- Patch #812986: Update turtle output even if not tracing.
1960
Vinay Sajip28e57612006-07-01 10:45:20 +00001961- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001962 Tkinter.BaseWidget.
1963
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001964- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1965
Martin v. Löwis337487e2006-06-17 09:15:14 +00001966- Patch #763580: Add name and value arguments to Tkinter variable
1967 classes.
1968
Georg Brandl83cc0d02006-06-14 08:50:03 +00001969- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1970 mime.types file for determining MIME types.
1971
Georg Brandl2605ca82006-06-14 06:08:31 +00001972- Bug #1339007: Shelf objects now don't raise an exception in their
1973 __del__ method when initialization failed.
1974
Martin v. Löwisd8251432006-06-14 05:21:04 +00001975- Patch #1455898: The MBCS codec now supports the incremental mode for
1976 double-byte encodings.
1977
Tim Peters43898b42006-06-14 04:09:25 +00001978- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1979 guarantee that adjacent triples in the return list always describe
1980 non-adjacent blocks. Previously, a pair of matching blocks could end
1981 up being described by multiple adjacent triples that formed a partition
1982 of the matching pair.
1983
Greg Ward0e0c9f42006-06-11 16:24:11 +00001984- Bug #1498146: fix optparse to handle Unicode strings in option help,
1985 description, and epilog.
1986
Greg Wardd1c797e2006-06-11 14:42:41 +00001987- Bug #1366250: minor optparse documentation error.
1988
Greg Ward7f547402006-06-11 00:40:49 +00001989- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1990 clarify docs.
1991
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001992- The wsgiref package has been added to the standard library.
1993
Nick Coghlan676725d2006-06-08 13:54:49 +00001994- The functions update_wrapper() and wraps() have been added to the functools
1995 module. These make it easier to copy relevant metadata from the original
1996 function when writing wrapper functions.
1997
Tim Petersd6a9eef2006-06-05 01:48:21 +00001998- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1999 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002000
Martin v. Löwis3f767792006-06-04 19:36:28 +00002001- Patch #1359618: Speed up charmap encoder by using a trie structure
2002 for lookup.
2003
Tim Petersd609b1a2006-06-02 23:22:51 +00002004- The functions in the ``pprint`` module now sort dictionaries by key
2005 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2006 if and only if its display required more than one line, although that
2007 wasn't documented. The new behavior increases predictability; e.g.,
2008 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2009
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002010- Patch #1497027: try HTTP digest auth before basic auth in urllib2
2011 (thanks for J. J. Lee).
2012
Georg Brandl2b330372006-05-28 20:23:12 +00002013- Patch #1496206: improve urllib2 handling of passwords with respect to
2014 default HTTP and HTTPS ports.
2015
George Yoshidaf3c65de2006-05-28 16:39:09 +00002016- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
2017
Bob Ippolito7298f272006-05-23 18:43:47 +00002018- Patch #1281707: speed up gzip.readline.
2019
Georg Brandlb89316f2006-05-17 15:51:16 +00002020- Patch #1180296: Two new functions were added to the locale module:
2021 format_string() to get the effect of "format % items" but locale-aware,
2022 and currency() to format a monetary number with currency sign.
2023
Georg Brandle3a25832006-05-17 14:56:04 +00002024- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2025 and several features added, such as speed and geometry control.
2026
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002027- Patch #1488881: add support for external file objects in bz2 compressed
2028 tarfiles.
2029
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002030- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2031 stdout arguments, making it possible to redirect input and output
2032 for remote debugging.
2033
2034- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2035 a couple of issues, notably handling of long file names using the
2036 GNU LONGNAME extension.
2037
2038- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2039 new flag when ``name`` is already the name of an option flag.
2040
2041- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2042 package.
2043
2044- Patch #1472854: make the rlcompleter.Completer class usable on non-
2045 UNIX platforms.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002080What's New in Python 2.5 alpha 2?
2081=================================
2082
2083*Release date: 27-APR-2006*
2084
2085Core and builtins
2086-----------------
2087
Thomas Heller1b046642006-04-18 18:51:06 +00002088- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2089 by converting these apis from macros into exported functions again:
2090
2091 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2092 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2093 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2094 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2095 PyRun_String Py_CompileString
2096
Martin v. Löwis45294a92006-04-18 06:24:08 +00002097- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2098
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002099- All uses of PyStructSequence_InitType have been changed to initialize
2100 the type objects only once, even if the interpreter is initialized
2101 multiple times.
2102
Neal Norwitz61546162006-04-14 05:20:28 +00002103- Bug #1454485, array.array('u') could crash the interpreter. This was
2104 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2105 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2106
2107- Py_UNICODE is unsigned. It was always documented as unsigned, but
2108 due to a bug had a signed value in previous versions.
2109
Tim Peters3a5e8b12006-04-11 01:44:07 +00002110- Patch #837242: ``id()`` of any Python object always gives a positive
2111 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2112 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002113 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002114 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002115
Tim Peters3a5e8b12006-04-11 01:44:07 +00002116 def __hash__(self):
2117 return id(self) # WRONG
2118
2119 because a hash result must be a (short) Python int but it was always
2120 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002121 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002122 was always usable as a hash value before this patch. That's no longer
2123 necessarily so.
2124
2125- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002126 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002127 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002128 #1454844)
2129
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002130- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2131 involving generators that have paused outside of any ``try`` or ``with``
2132 blocks. (In 2.5a1, a paused generator that was part of a reference
2133 cycle could not be garbage collected, regardless of whether it was
2134 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00002135
Anthony Baxter51bcb682006-04-05 14:51:42 +00002136Extension Modules
2137-----------------
2138
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00002139- Patch #1191065: Fix preprocessor problems on systems where recvfrom
2140 is a macro.
2141
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002142- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2143 fails with an error condition.
2144
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002145- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2146
2147- Bug #1117761: bsddb.*open() no longer raises an exception when using
2148 the cachesize parameter.
2149
2150- Bug #1149413: bsddb.*open() no longer raises an exception when using
2151 a temporary db (file=None) with the 'n' flag to truncate on open.
2152
2153- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2154 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002155
Armin Rigoa9017c32006-04-19 11:50:27 +00002156- Patch #1062014: AF_UNIX sockets under Linux have a special
2157 abstract namespace that is now fully supported.
2158
Anthony Baxter51bcb682006-04-05 14:51:42 +00002159Library
2160-------
2161
Peter Astrand7d1d4362006-07-14 14:04:45 +00002162- Bug #1223937: subprocess.CalledProcessError reports the exit status
2163 of the process using the returncode attribute, instead of
2164 abusing errno.
2165
Tim Peters711bf302006-04-25 03:31:36 +00002166- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2167 a doctest to be skipped (the code is not run, and the expected output
2168 or exception is ignored).
2169
Nick Coghlanda2268f2006-04-24 04:37:15 +00002170- Fixed contextlib.nested to cope with exceptions being raised and
2171 caught inside exit handlers.
2172
Greg Wardab05edc2006-04-23 03:47:58 +00002173- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2174 hex, octal, or binary; add ``append_const`` action; keep going if
2175 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2176 added ``epilog`` for better help generation).
2177
Tim Peters21fbd572006-04-21 21:18:10 +00002178- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2179 called from a thread spawned as a side effect of importing a module.
2180
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002181- The pydoc module now supports documenting packages contained in
2182 .zip or .egg files.
2183
2184- The pkgutil module now has several new utility functions, such
2185 as ``walk_packages()`` to support working with packages that are either
2186 in the filesystem or zip files.
2187
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002188- The mailbox module can now modify and delete messages from
2189 mailboxes, in addition to simply reading them. Thanks to Gregory
2190 K. Johnson for writing the code, and to the 2005 Google Summer of
2191 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002192
Tim Petersc7605f22006-04-17 21:12:33 +00002193- The ``__del__`` method of class ``local`` in module ``_threading_local``
2194 returned before accomplishing any of its intended cleanup.
2195
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002196- Patch #790710: Add breakpoint command lists in pdb.
2197
Martin v. Löwis0db2a982006-04-16 20:55:38 +00002198- Patch #1063914: Add Tkinter.Misc.clipboard_get().
2199
Martin v. Löwis4b501e62006-04-15 08:41:11 +00002200- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
2201
Anthony Baxtere29002c2006-04-12 12:07:31 +00002202- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2203 Windows. Bug #1469163.
2204
Phillip J. Eby47032112006-04-11 01:07:43 +00002205- The warnings, linecache, inspect, traceback, site, and doctest modules
2206 were updated to work correctly with modules imported from zipfiles or
2207 via other PEP 302 __loader__ objects.
2208
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002209- Patch #1467770: Reduce usage of subprocess._active to processes which
2210 the application hasn't waited on.
2211
Martin v. Löwisb04dee92006-04-10 08:34:21 +00002212- Patch #1462222: Fix Tix.Grid.
2213
Neal Norwitza31bf182006-04-09 03:35:43 +00002214- Fix exception when doing glob.glob('anything*/')
2215
Skip Montanaro262fb922006-04-21 02:31:07 +00002216- The pstats.Stats class accepts an optional stream keyword argument to
2217 direct output to an alternate file-like object.
2218
Anthony Baxter51bcb682006-04-05 14:51:42 +00002219Build
2220-----
2221
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002222- The Makefile now has a reindent target, which runs reindent.py on
2223 the library.
2224
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002225- Patch #1470875: Building Python with MS Free Compiler
2226
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002227- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002228
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002229- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2230 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002231 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002232 CXX from --with-cxx-main, see description in README.
2233
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002234- Patch #1429775: Link extension modules with the shared libpython.
2235
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002236- Fixed a libffi build problem on MIPS systems.
2237
Tim Peters8931ff12006-05-13 23:28:20 +00002238- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2239 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2240 and "%zu" for unsigned integers of type ``size_t``.
2241
Anthony Baxter51bcb682006-04-05 14:51:42 +00002242Tests
2243-----
2244
Nick Coghlanda2268f2006-04-24 04:37:15 +00002245- test_contextlib now checks contextlib.nested can cope with exceptions
2246 being raised and caught inside exit handlers.
2247
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002248- test_cmd_line now checks operation of the -m and -c command switches
2249
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002250- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2251 it separately and by hand. It also wasn't cleaning up its changes to
2252 the current Decimal context.
2253
Thomas Woutersabd08882006-04-26 15:53:30 +00002254- regrtest.py now has a -M option to run tests that test the new limits of
2255 containers, on 64-bit architectures. Running these tests is only sensible
2256 on 64-bit machines with more than two gigabytes of memory. The argument
2257 passed is the maximum amount of memory for the tests to use.

2266-------------
2267
Tim Petersb06d28c2006-05-12 01:57:59 +00002268- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2269
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002270- PEP 343: Added Context Types section to the library reference
2271 and attempted to bring other PEP 343 related documentation into
2272 line with the implementation and/or python-dev discussions.
2273
Tim Peters8dc73d22006-04-24 02:03:16 +00002274- Bug #1337990: clarified that ``doctest`` does not support examples
2275 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002278What's New in Python 2.5 alpha 1?
2279=================================
2280
Anthony Baxterebed3f62006-04-03 15:03:44 +00002281*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002282
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002283Core and builtins
2284-----------------
2285
Nick Coghlan43832302006-04-23 17:04:07 +00002286- PEP 338: -m command line switch now delegates to runpy.run_module
2287 allowing it to support modules in packages and zipfiles
2288
Martin v. Löwisc661b882006-04-20 04:54:23 +00002289- On Windows, .DLL is not an accepted file name extension for
2290 extension modules anymore; extensions are only found if they
2291 end in .PYD.
2292
Martin v. Löwisea62d252006-04-03 10:56:49 +00002293- Bug #1421664: sys.stderr.encoding is now set to the same value as
2294 sys.stdout.encoding.
2295
Neal Norwitz92e212f2006-04-03 04:48:37 +00002296- __import__ accepts keyword arguments.
2297
Georg Brandlccadf842006-03-31 18:54:53 +00002298- Patch #1460496: round() now accepts keyword arguments.
2299
Anthony Baxter262c00a2006-03-30 10:53:17 +00002300- Fixed bug #1459029 - unicode reprs were double-escaped.
2301
Hye-Shik Changd478f342006-03-23 12:32:36 +00002302- Patch #1396919: The system scope threads are reenabled on FreeBSD
2303 5.4 and later versions.
2304
Neal Norwitze98ccf62006-03-23 05:39:47 +00002305- Bug #1115379: Compiling a Unicode string with an encoding declaration
2306 now gives a SyntaxError.
2307
Georg Brandlabd1ff82006-03-18 07:59:59 +00002308- Previously, Python code had no easy way to access the contents of a
2309 cell object. Now, a ``cell_contents`` attribute has been added
2310 (closes patch #1170323).
2311
Tim Peterscf79aac2006-03-16 01:14:46 +00002312- Patch #1123430: Python's small-object allocator now returns an arena to
2313 the system ``free()`` when all memory within an arena becomes unused
2314 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2315 freed. Some applications will see a drop in virtual memory size now,
2316 especially long-running applications that, from time to time, temporarily
2317 use a large number of small objects. Note that when Python returns an
2318 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002319 platform C library will in turn return that memory to the operating system.
2320 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002321 appears to be effective at least on Microsoft C and gcc-based systems.
2322 Thanks to Evan Jones for hard work and patience.
2323
Georg Brandl533ff6f2006-03-08 18:09:27 +00002324- Patch #1434038: property() now uses the getter's docstring if there is
2325 no "doc" argument given. This makes it possible to legitimately use
2326 property() as a decorator to produce a read-only property.
2327
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002328- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2329 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2330 of requiring an int or long in slicing and a few other contexts, enabling
2331 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2332
Neal Norwitz995acdf2006-03-07 05:01:00 +00002333- Fixed various bugs reported by Coverity's Prevent tool.
2334
Brett Cannonbf364092006-03-01 04:25:17 +00002335- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2336 new exception base class, BaseException, which has a new message attribute.
2337 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2338 Raising a string exception now raises a DeprecationWarning.
2339
Thomas Woutersfb609f42006-02-28 16:37:25 +00002340- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2341 explicitly relative, using 'from .module import name' to mean 'from the same
2342 package as this module is in. Imports without dots still default to the
2343 old relative-then-absolute, unless 'from __future__ import
2344 absolute_import' is used.
2345
Brett Cannona7446e32006-02-27 23:39:10 +00002346- Properly check if 'warnings' raises an exception (usually when a filter set
2347 to "error" is triggered) when raising a warning for raising string
2348 exceptions.
2349
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002350- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002351 The name was removed from Include/code.h.
2352
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002353- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002354
Guido van Rossum1968ad32006-02-25 22:38:04 +00002355- Patch 1433928:
2356 - The copy module now "copies" function objects (as atomic objects).
2357 - dict.__getitem__ now looks for a __missing__ hook before raising
2358 KeyError.
2359
Tim Peters84ef21c2006-02-28 20:39:06 +00002360- PEP 343: with statement implemented. Needs ``from __future__ import
2361 with_statement``. Use of 'with' as a variable will generate a warning.
2362 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002363 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002364 The following objects have __context__ methods:
2365 - The built-in file type.
2366 - The thread.LockType type.
2367 - The following types defined by the threading module:
2368 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2369 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002370
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002371- Fix the encodings package codec search function to only search
2372 inside its own package. Fixes problem reported in patch #1433198.
2373
2374 Note: Codec packages should implement and register their own
2375 codec search function. PEP 100 has the details.
2376
Tim Peters9ea89d22006-06-04 03:26:02 +00002377- PEP 353: Using ``Py_ssize_t`` as the index type.
2378
2379- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2380 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2381 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2382 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2383 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002384
Neal Norwitzfc76d632006-01-10 06:03:13 +00002385- Patch #1400181, fix unicode string formatting to not use the locale.
2386 This is how string objects work. u'%f' could use , instead of .
2387 for the decimal point. Now both strings and unicode always use periods.
2388
Neal Norwitz671b9e32006-01-09 07:07:12 +00002389- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2390 configure would break checking curses.h.
2391
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002392- Bug #959576: The pwd module is now builtin. This allows Python to be
2393 built on UNIX platforms without $HOME set.
2394
Neal Norwitzc10978f2005-12-19 06:07:16 +00002395- Bug #1072182, fix some potential problems if characters are signed.
2396
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002397- Bug #889500, fix line number on SyntaxWarning for global declarations.
2398
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002399- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2400
Neal Norwitze7214a12005-12-18 05:03:17 +00002401- Support for converting hex strings to floats no longer works.
2402 This was not portable. float('0x3') now raises a ValueError.
2403
Barry Warsaw2a38a862005-12-18 01:27:35 +00002404- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002405 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002406 is now displayed in interactive prompt banner.
2407
Georg Brandlfa166682005-12-17 21:45:17 +00002408- Implementation of PEP 341 - Unification of try/except and try/finally.
2409 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002410 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002411
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002412- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2413 now encodes backslash correctly.
2414
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002415- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2416
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002417- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002418 and long longs.
2419
Neal Norwitz67715f02005-11-09 06:59:35 +00002420- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002421 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002422 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002423
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002424- Replaced most Unicode charmap codecs with new ones using the
2425 new Unicode translate string feature in the builtin charmap
2426 codec; the codecs were created from the mapping tables available
2427 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2428 encodings now include a mapping for the Apple logo)
2429
Tim Peterse3547fd2005-12-16 23:13:57 +00002430- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002431
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002432- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002433
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002434- A new AST parser implementation was completed. The abstract
2435 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002436 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002437
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002438- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002439 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2440
Neal Norwitz708e51a2005-10-03 04:48:15 +00002441- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2442
Neal Norwitz11bd1192005-10-03 00:54:56 +00002443- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2444 Provide a warning when a directory is passed on the command line.
2445
Neal Norwitz40d37812005-10-02 01:48:49 +00002446- Fix segfault with invalid coding.
2447
2448- SF bug #772896: unknown encoding results in MemoryError.
2449
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002450- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002451 supported a __len__() method which evaluated to False when the iterator
2452 was empty.
2453
Guido van Rossum630db602005-09-20 18:49:54 +00002454- On 64-bit platforms, when __len__() returns a value that cannot be
2455 represented as a C int, raise OverflowError.
2456
Skip Montanarof8948ca2005-09-19 03:54:46 +00002457- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002458 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002459
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002460- SF bug #893549: parsing keyword arguments was broken with a few format
2461 codes.
2462
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002463- Changes donated by Elemental Security to make it work on AIX 5.3
2464 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2465 bug #105470: test_pwd fails on 64bit system (Opteron).
2466
Guido van Rossum539c6622005-09-14 17:49:54 +00002467- Changes donated by Elemental Security to make it work on HP-UX 11 on
2468 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2469
Georg Brandl4550b8d2005-08-26 06:43:52 +00002470- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002471 (fixes bug #1119418).
2472
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002473- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2474
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002475- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2476 exceptions that cause a function to exit.
2477
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002478- The implementation of set() and frozenset() was revised to use its
2479 own internal data structure. Memory consumption is reduced by 1/3
2480 and there are modest speed-ups as well. The API is unchanged.
2481
Tim Petersde7990b2005-07-17 23:45:23 +00002482- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2483
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002484- SF bug #1229429: PyObject_CallMethod failed to decrement some
2485 reference counts in some error exit cases.
2486
Tim Petersecc6e6a2005-07-10 22:30:55 +00002487- SF bug #1185883: Python's small-object memory allocator took over
2488 a block managed by the platform C library whenever a realloc specified
2489 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002490 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002491 portable way to copy data from the C-managed block into Python's
2492 small-object space without risking a memory fault. Python's small-object
2493 realloc now leaves such blocks under the control of the platform C
2494 realloc.
2495
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002496- SF bug #1232517: An overflow error was not detected properly when
2497 attempting to convert a large float to an int in os.utime().
2498
Raymond Hettinger3296e692005-06-29 23:29:56 +00002499- SF bug #1224347: hex longs now print with lowercase letters just
2500 like their int counterparts.
2501
Michael W. Hudson188d4362005-06-20 16:52:57 +00002502- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2503 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2504 interpreter states; back out that fix and do a better job (see
2505 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2506 for a longer write-up of the problem).
2507
Michael W. Hudsondf888462005-06-03 14:41:55 +00002508- SF patch #1180995: marshal now uses a binary format by default when
2509 serializing floats.
2510
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002511- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2512 the routines that promise to produce IEEE 754 binary representations
2513 of floats now simply copy bytes around.
2514
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002515- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2516 278.
2517
Brett Cannonc3647ac2005-04-26 03:45:26 +00002518- patch #1109424: int, long, float, complex, and unicode now check for the
2519 proper magic slot for type conversions when subclassed. Previously the
2520 magic slot was ignored during conversion. Semantics now match the way
2521 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002522 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002523 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002524 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002525
Barry Warsawc8d907c2005-04-19 23:43:40 +00002526- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2527 NULL, now raise an AttributeError when attempting to set or delete the
2528 attribute. Previously a TypeError was raised, but this was inconsistent
2529 with the equivalent pure-Python implementation.
2530
Michael W. Hudson774479c2005-04-18 08:46:17 +00002531- It is now safe to call PyGILState_Release() before
2532 PyEval_InitThreads() (note that if there is reason to believe there
2533 are multiple threads around you still must call PyEval_InitThreads()
2534 before using the Python API; this fix is for extension modules that
2535 have no way of knowing if Python is multi-threaded yet).
2536
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002537- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2538 disabled caused a crash.
2539
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002540- Bug #1165306: instancemethod_new allowed the creation of a method
2541 with im_class == im_self == NULL, which caused a crash when called.
2542
Tim Petersecc6e6a2005-07-10 22:30:55 +00002543- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002544 fixes the crash seen in bug #1165761
2545
Raymond Hettinger96229b12005-03-11 06:49:40 +00002546- Added two new builtins, any() and all().
2547
Brett Cannon409d8f22005-03-05 06:47:57 +00002548- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002549 (e.g., ``class C(): pass`` is no longer a syntax error).
2550 Patch #1176012 added support to the 'parser' module and 'compiler' package
2551 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002552
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002553- Patch #1115086: Support PY_LONGLONG in structmember.
2554
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002555- Bug #1155938: new style classes did not check that __init__() was
2556 returning None.
2557
Tim Petersecc6e6a2005-07-10 22:30:55 +00002558- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002559 ('\') with a specific error message.
2560
Martin v. Löwisff232d72005-03-03 09:24:38 +00002561- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2562
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002563- Bug #1124295: the __name__ attribute of file objects was
2564 inadvertently made inaccessible in restricted mode.
2565
Tim Petersecc6e6a2005-07-10 22:30:55 +00002566- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002567 an ferror() call.
2568
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002569- min() and max() now support key= arguments with the same meaning as in
2570 list.sort().
2571
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002572- The peephole optimizer now performs simple constant folding in expressions:
2573 (2+3) --> (5).
2574
Raymond Hettingera422c342005-01-11 03:03:27 +00002575- set and frozenset objects can now be marshalled. SF #1098985.
2576
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002577- Bug #1077106: Poor argument checking could cause memory corruption
2578 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002579
Jeremy Hyltonab630502005-02-04 18:44:06 +00002580- The parser did not complain about future statements in illegal
2581 positions. It once again reports a syntax error if a future
2582 statement occurs after anything other than a doc string.
2583
Neil Schemenauercf52c072005-08-12 17:34:58 +00002584- Change the %s format specifier for str objects so that it returns a
2585 unicode instance if the argument is not an instance of basestring and
2586 calling __str__ on the argument returns a unicode instance.
2587
Tim Petersf4e69282006-02-27 17:15:31 +00002588- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2589 current thread state when the auto-GIL-state machinery knows about
2590 it (since the thread state is being deleted, continuing to remember it
2591 can't help, but can hurt if another thread happens to get created with
2592 the same thread id).
2593
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002594Extension Modules
2595-----------------
2596
Georg Brandl43f08a82006-03-31 18:01:16 +00002597- Patch #1380952: fix SSL objects timing out on consecutive read()s
2598
Neal Norwitz05a45592006-03-20 06:30:08 +00002599- Patch #1309579: wait3 and wait4 were added to the posix module.
2600

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002784- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2785 been renamed to have only a single underscore prefix. This was done to
2786 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002787
Nick Coghlan43832302006-04-23 17:04:07 +00002788- PEP 338: new module runpy defines a run_module function to support
2789 executing modules which provide access to source code or a code object
2790 via the PEP 302 import mechanisms.
2791
Anthony Baxter93f5b932006-04-03 08:05:07 +00002792- The email module's parsedate_tz function now sets the daylight savings

2800 in attribute values.
2801
Anthony Baxterc51ee692006-04-01 00:57:31 +00002802- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002803 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002804 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002805 module will not be built.
2806
Tim Petersc17976e2006-04-01 00:26:53 +00002807- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2808 aren't officially supported here, and trying to use them will probably
2809 raise an exception some day. But dicts have been allowed, and "mostly
2810 worked", so support for them won't go away without warning.
2811
Georg Brandl338ef7d2006-03-31 18:42:16 +00002812- Bug #1445068: getpass.getpass() can now be given an explicit stream

2830
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002831- email 4.0 package now integrated. This is largely the same as the email 3.0
2832 package that was included in Python 2.3, except that PEP 8 module names are
2833 now used (e.g. mail.message instead of email.Message). The MIME classes
2834 have been moved to a subpackage (e.g. email.mime.text instead of
2835 email.MIMEText). The old names are still supported for now. Several
2836 deprecated Message methods have been removed and lots of bugs have been
2837 fixed. More details can be found in the email package documentation.
2838
Walter Dörwald40108c92006-03-27 08:15:44 +00002839- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2840 (a subclass of tuple) that provides incremental decoders and encoders
2841 (a way to use stateful codecs without the stream API). Python functions
2842 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2843 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2844 have been added.

2847 a ValueError instead of a StopIteration now (like file and cString.String do).

2927
2928 "The consensus of researchers in this area (at least as
2929 expressed at the NIST Hash Function Workshop 10/31/05),
2930 is that SHA-256 is a good choice for the time being, but
2931 that research should continue, and other alternatives may
2932 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002933

3120 dictates.
3121 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003122 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003123 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003124 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3125 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003126 + reader now allows \r characters to be quoted (previously it only allowed
3127 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003128 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003129 + Dialect classes passed to the module are no longer instantiated by
3130 the module before being parsed (the former validation scheme required
3131 this, but the mechanism was unreliable).
3132 + The dialect registry now contains instances of the internal
3133 C-coded dialect type, rather than references to python objects.
3134 + the internal c-coded dialect type is now immutable.
3135 + register_dialect now accepts the same keyword dialect specifications
3136 as the reader and writer, allowing the user to register dialects
3137 without first creating a dialect class.
3138 + a configurable limit to the size of parsed fields has been added -
3139 previously, an unmatched quote character could result in the entire
3140 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003141 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003142 the parser field size limit (returning the former limit). The initial
3143 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003144 + A line_num attribute has been added to the reader object, which tracks
3145 the number of lines read from the source iterator. This is not
3146 the same as the number of records returned, as records can span
3147 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003148 + reader and writer objects were not being registered with the cyclic-GC.
3149 This has been fixed.
3150
Brett Cannone6539c42005-01-08 02:43:53 +00003151- _DummyThread objects in the threading module now delete self.__block that is
3152 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3153 lock primitives tend to be limited in number and thus should not be wasted on
3154 a _DummyThread object. Fixes bug #1089632.
3155
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003156- The imghdr module now detects Exif files.
3157
Raymond Hettinger6065d322004-12-20 23:51:53 +00003158- StringIO.truncate() now correctly adjusts the size attribute.
3159 (Bug #951915).
3160
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003161- locale.py now uses an updated locale alias table (built using
3162 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3163 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003164 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003165
Raymond Hettinger3557f422004-12-07 12:02:02 +00003166- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3167
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003168- the pickle module no longer accepts the deprecated None option in the
3169 args tuple returned by __reduce__().
3170
Brett Cannon84667c02004-12-07 03:25:18 +00003171- optparse now optionally imports gettext. This allows its use in setup.py.
3172
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003173- the pickle module no longer uses the deprecated bin parameter.
3174
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003175- the shelve module no longer uses the deprecated binary parameter.
3176

3178
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003179- the filecmp module no longer uses the deprecated use_statcache argument.
3180
Raymond Hettinger664347b2004-12-04 21:21:53 +00003181- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3182 extended or overridden by subclasses. Formerly, the subclassed method would
3183 be ignored by the rest of the module. (Bug #1078905).
3184
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003185- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003186 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003187
Walter Dörwald36733692004-12-22 12:50:50 +00003188- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3189 once when a size argument is given. This prevents a buffer overflow in the
3190 tokenizer with very long source lines.
3191
Barry Warsaw538561e2006-01-01 21:48:54 +00003192- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3193 immediately after creating the object, without any intervening
3194 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003195
Skip Montanaro05885812005-01-16 20:48:27 +00003196- The reconvert.quote function can now emit triple-quoted strings. The
3197 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003198
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003199- ``UserString.MutableString`` now supports negative indices in
3200 ``__setitem__`` and ``__delitem__``
3201
Greg Ward40407942005-03-05 02:53:17 +00003202- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3203 correctly.
3204
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003205- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3206 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3207 character even if the user has passed a size parameter to get a proper
3208 line ending. Remove the special handling of a "\r\n" that has been split
3209 between two lines.
3210
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003211- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3212 about illegal code points. The codec now supports PEP 293 style error
3213 handlers.
3214
Walter Dörwald78a78b02005-09-01 12:04:29 +00003215- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003216 from the input stream, so that the output is a byte string in the correct
3217 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003218
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003219- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3220 considering it exactly like a '*'.
3221
Walter Dörwald007f8df2005-10-09 19:42:27 +00003222- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3223 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003224
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003225- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3226
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003227- Patch #1413711: Certain patterns of differences were making difflib
3228 touch the recursion limit.
3229
Walter Dörwald58917a62006-03-31 15:26:22 +00003230- Bug #947906: An object oriented interface has been added to the calendar
3231 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003232 called as a script (e.g. via ``python -mcalendar``). Localized month and
3233 weekday names can be ouput (even if an exotic encoding is used) using
3234 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003235
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003236Build
3237-----
3238
Neal Norwitz602d3392006-03-31 08:21:40 +00003239- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3240 by using -mieee gcc option.
3241
Martin v. Löwis86d66262006-02-17 08:40:11 +00003242- Patch #1432345: Make python compile on DragonFly.
3243
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003244- Build support for Win64-AMD64 was added.
3245
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003246- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3247
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003248- Patch #881820: look for openpty and forkpty also in libbsd.
3249
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003250- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3251 The zlib module is now builtin on Windows.
3252
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003253- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3254
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003255- Bug #1189330: configure did not correctly determine the necessary
3256 value of LINKCC if python was built with GCC 4.0.
3257
Trent Mick8321b422005-07-26 02:29:21 +00003258- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3259 vulnerability in zlib 1.2.1 and 1.2.2.
3260
Brett Cannon08cd5982005-04-24 22:26:38 +00003261- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3262 flags that change binary compatibility. Changes were also made to
3263 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003264 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003265
Bob Ippolitoed233462005-03-29 13:47:59 +00003266- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3267 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3268 no longer exists). This configure patch makes things right.
3269
Martin v. Löwise2713be2005-03-08 15:03:08 +00003270- Bug #1158607: Build with --disable-unicode again.
3271
Brett Cannon46d96232005-02-16 00:07:19 +00003272- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3273 defined. Discovered as a result of not being able to build on OS X.
3274
Brett Cannon516592f2004-12-07 00:42:59 +00003275- setup.py now uses the directories specified in LDFLAGS using the -L option
3276 and in CPPFLAGS using the -I option for adding library and include
3277 directories, respectively, for compiling extension modules against. This has
3278 led to the core being compiled using the values in CPPFLAGS. It also removes
3279 the need for the special-casing of both DarwinPorts and Fink for darwin since
3280 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3281 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3282 Fink, ``-I/opt/local/include`` for DarwinPorts).
3283
Brett Cannon43802422005-02-10 20:48:03 +00003284- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3285 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3286 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3287 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003289C API
3290-----
3291
Tim Petersc9d78aa2006-03-26 23:27:58 +00003292- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3293 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3294 is obtained via the ``PyObject_`` family, it must be released via the
3295 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3296 always been officially true, but when Python's small-object allocator was
3297 introduced, an attempt was made to cater to a few extension modules
3298 discovered at the time that obtained memory via ``PyObject_New`` but
3299 released it via ``PyMem_DEL``. It's years later, and if such code still
3300 exists it will fail now (probably with segfaults, but calling wrong
3301 low-level memory management functions can yield many symptoms).
3302
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003303- Added a C API for set and frozenset objects.
3304
Raymond Hettinger66517482004-12-03 11:45:13 +00003305- Removed PyRange_New().
3306
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003307- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3308 mapping argument now. This string is used as a mapping table. Byte values
3309 greater than the length of the string and 0xFFFE are treated as undefined
3310 mappings.
