Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000014
Jeffrey Yasskin6f5d3f32008-12-10 17:23:20 +000015- Issue #4597: Fixed several opcodes that weren't always propagating
16 exceptions.
17
Jeffrey Yasskin478a1aa2008-12-10 07:28:12 +000018- Issue #4589: Propagated an exception thrown by a context manager's
19 __exit__ method's result while it's being converted to bool.
20
Amaury Forgeot d'Arcef633d72008-11-18 22:35:48 +000021- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
22
Benjamin Peterson42fe1a22008-11-17 23:35:24 +000023- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
24
Benjamin Peterson6f08e852008-11-03 15:19:35 +000025- Issue #4048: The parser module now correctly validates relative imports.
26
Amaury Forgeot d'Arc3b335ff2008-10-30 21:40:05 +000027- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
28 method does not return iterators for the 4th and 5th items.
29
Amaury Forgeot d'Arcb50f9922008-09-26 22:46:01 +000030- Issue #3967: Fixed a crash in the count() and find() methods of string-like
31 objects, when the "start" parameter is a huge value.
32
Benjamin Petersond1c7d072008-09-25 20:46:05 +000033- Issue #3936: The parser warnings for using "as" and "with" as variable names
34 didn't fire after import statements.
35
Amaury Forgeot d'Arcafa0d582008-09-01 20:05:08 +000036- Issue #3751: str.rpartition would perform a left-partition when called with
37 a unicode argument.

40 object was stored in the freelist.
41
Neal Norwitz4f3be8a2008-07-31 17:08:14 +000042- Apply security patches from Apple.
43
Neal Norwitz83ac0142008-07-28 05:06:20 +000044- Issue #2620: Overflow checking when allocating or reallocating memory
45 was not always being done properly in some python types and extension
46 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
47 all been updated to perform better checks and places in the code that
48 would previously leak memory on the error path when such an allocation
49 failed have been fixed.
50
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +000051- Issue #2242: Fix a crash when decoding invalid utf-7 input on certain
52 Windows / Visual Studio versions.
53
Mark Dickinsonab396e02008-07-16 11:04:17 +000054- Issue #3360: Fix incorrect parsing of '020000000000.0', which
55 produced a ValueError instead of giving the correct float.
56
Amaury Forgeot d'Arcceda6a62008-07-01 20:52:56 +000057- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
58 set to a custom object whose write() method happens to install
59 another file in sys.stdout.
60
Amaury Forgeot d'Arcb15bdf72008-07-01 20:59:49 +000061- Issue #3088: Corrected a race condition in classes derived from
62 threading.local: the first member set by a thread could be saved in
63 another thread's dictionary.
64
Amaury Forgeot d'Arc3255e132008-06-16 19:22:42 +000065- Issue #3100: Corrected a crash on deallocation of a subclassed weakref which
66 holds the last (strong) reference to its referent.
67
Guido van Rossumaa975432008-04-10 22:43:58 +000068- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
69 having a self-referential tuple, which is possible from C code. Nor did
70 object's tp_str consider that a type's tp_str could do something that could
71 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
72 respectively, fixed the issues. (Backport of r58288 from trunk.)
73
Georg Brandld9f1da02008-03-29 01:50:46 +000074- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
75 cannot be executed.

78 reference on the outer class name.
79
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000080- Issue #1477: With narrow Unicode builds, the unicode escape sequence
81 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
82 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
83 UTF-16 surrogates are generated in this case, like normal unicode literals
84 and the 'unicode-escape' codec.
85
Neal Norwitzb3635f92008-03-18 04:17:36 +000086- Issue #2321: use pymalloc for unicode object string data to reduce
87 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +000088
Sean Reifscheider4af861c2008-03-20 17:39:31 +000089- Issue #2238: Some syntax errors in *args and **kwargs expressions could give
90 bogus error messages.
91
Gregory P. Smith14acde32008-04-09 23:41:13 +000092- Issue #2587: In the C API, PyString_FromStringAndSize() takes a signed size
93 parameter but was not verifying that it was greater than zero. Values
94 less than zero will now raise a SystemError and return NULL to indicate a
95 bug in the calling C code.
96
Gregory P. Smith9aa040d2008-06-02 00:07:25 +000097- Issue #2588, #2589: Fix potential integer underflow and overflow
98 conditions in the PyOS_vsnprintf C API function.
99
Gregory P. Smithcae7f882008-09-07 06:44:12 +0000100- Issue #1204: The configure script now tests for additional libraries
101 that may be required when linking against readline. This fixes issues
102 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
Georg Brandld9f1da02008-03-29 01:50:46 +0000103
Gregory P. Smitha7a94a02008-09-22 00:22:44 +0000104- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
105 library targets in the Makefile.

128
Thomas Heller275e2292008-08-19 17:17:37 +0000129- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python

131 error when they failed.
132
Amaury Forgeot d'Arc22679b82008-08-18 19:33:42 +0000133- Issue #2234: distutils failed for some versions of the cygwin compiler. The
134 version reported by these tools does not necessarily follow the python

Mark Dickinsonbfdbfd42008-03-25 18:58:13 +0000162- Issue #2482: Make sure that the coefficient of a Decimal is always
163 stored as a str instance, not as a unicode instance. This ensures

165 regression from Python 2.5.1 to Python 2.5.2.
166

Martin v. Löwis897704d2007-06-08 17:29:40 +0000283Core and builtins
284-----------------
285
Martin v. Löwis73c01d42008-02-14 11:26:18 +0000286- Added checks for integer overflows, contributed by Google. Some are
287 only available if asserts are left in the code, in cases where they
288 can't be triggered from Python code.
289
Amaury Forgeot d'Arc3e5f8a62008-02-08 01:05:21 +0000290- Issue #2045: Fix an infinite recursion triggered when printing a subclass of
291 collections.defaultdict, if its default_factory is set to a bound method.
292
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000293- Issue #1920: "while 0" statements were completely removed by the compiler,
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000294 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000295 the condition is false. Now the compiler correctly emits bytecode for the
296 "else" suite.
297
Guido van Rossumd933e0a2008-01-24 18:28:37 +0000298- A few crashers fixed: weakref_in_del.py (issue #1377858);
299 loosing_dict_ref.py (issue #1303614, test67.py);
300 borrowed_ref_[34].py (not in tracker).
301
302- Fix for #1303614 and #1174712 backported from the trunk:
303 __dict__ descriptor abuse for subclasses of built-in types;
304 subclassing from both ModuleType and another built-in types.

883
Thomas Heller8bf469d2007-03-09 20:48:57 +0000884- Bug #1651235: When a tuple was passed to a ctypes function call,

Georg Brandld59ea472007-03-08 18:37:35 +0000894- unittest now verifies more of its assumptions. In particular, TestCase
895 and TestSuite subclasses (not instances) are no longer accepted in
896 TestSuite.addTest(). This should cause no incompatibility since it
897 never made sense with ordinary subclasses -- the failure just occurred
898 later, with a more cumbersome exception.

Brett Cannon19d76c52006-09-09 07:18:44 +00001117- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

Neal Norwitzff4b63b2006-08-04 04:50:21 +00001250
Anthony Baxterb4096662006-08-16 03:42:26 +00001251*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001252
1253Core and builtins
1254-----------------
1255
Neal Norwitz24b6f202006-09-05 04:43:56 +00001256- Fix infinite recursion when subclassing long and overriding __hash__.
1257
1258- Fix concatenation (+=) of long strings.
1259
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001260- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001261 compared equal or unequal to a string and a UnicodeDecodeError
1262 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001263
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001264 Instead, the equal (==) and unequal (!=) comparison operators will
1265 now issue a UnicodeWarning and interpret the two objects as
1266 unequal. The UnicodeWarning can be filtered as desired using
1267 the warning framework, e.g. silenced completely, turned into an
1268 exception, logged, etc.
1269
1270 Note that compare operators other than equal and unequal will still
1271 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001272
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001273- Fix segfault when doing string formatting on subclasses of long.
1274
1275- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1276 with new-style classes.
1277
1278- Fix bug related to __len__ functions returning negative values with
1279 classic classes.
1280
1281- Patch #1538606, Fix __index__() clipping. There were some problems
1282 discovered with the API and how integers that didn't fit into Py_ssize_t
1283 were handled. This patch attempts to provide enough alternatives
1284 to effectively use __index__.
1285
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001286- Bug #1536021: __hash__ may now return long int; the final hash
1287 value is obtained by invoking hash on the long int.
1288
Thomas Hellerab1049c2006-08-08 17:37:00 +00001289- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1290
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001291- Bug #1535165: fixed a segfault in input() and raw_input() when
1292 sys.stdin is closed.
1293
Thomas Heller74d36f02006-08-04 18:17:40 +00001294- On Windows, the PyErr_Warn function is now exported from
1295 the Python dll again.
1296
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001297- Bug #1191458: tracing over for loops now produces a line event
1298 on each iteration. Fixing this problem required changing the .pyc
1299 magic number. This means that .pyc files generated before 2.5c1
1300 will be regenerated.
1301
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001302- Bug #1333982: string/number constants were inappropriately stored
1303 in the byte code and co_consts even if they were not used, ie
1304 immediately popped off the stack.
1305
Georg Brandle9462c72006-08-04 18:03:37 +00001306- Fixed a reference-counting problem in property().

1309Library
1310-------
1311
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001312- Fix a bug in the ``compiler`` package that caused invalid code to be
1313 generated for generator expressions.
1314
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001315- The distutils version has been changed to 2.5.0. The change to
1316 keep it programmatically in sync with the Python version running
1317 the code (introduced in 2.5b3) has been reverted. It will continue
1318 to be maintained manually as static string literal.
1319
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001320- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001321 and this cannot be converted to the required C type, an exception is
1322 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001323 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001324
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001325- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001326 an exception.
1327
Tim Peterscbdd3502006-09-05 01:47:53 +00001328- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001329 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001330 workarounds for clocks with low resolution, to stop the code yielding
1331 duplicate UUIDs.
1332
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001333- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1334 before raising SystemExit, allowing IDLE to honor quit() and exit().
1335
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001336- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1337
Georg Brandl7a1af772006-08-14 21:55:28 +00001338- Patch #1536071: trace.py should now find the full module name of a
1339 file correctly even on Windows.
1340
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001341- logging's atexit hook now runs even if the rest of the module has
1342 already been cleaned up.
1343
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001344- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001345
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001346- Bug #1531405, format_exception no longer raises an exception if
1347 str(exception) raised an exception.
1348
Neil Schemenauer06ded092006-08-04 16:20:30 +00001349- Fix a bug in the ``compiler`` package that caused invalid code to be
1350 generated for nested functions.

1361 raises the correct exceptions.
1362
Thomas Heller1ce433e2006-08-14 16:20:04 +00001363- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1364 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1365
Thomas Heller86720042006-08-14 11:17:48 +00001366- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1367 uses the _as_parameter_ attribute when objects are passed to foreign
1368 function calls. The ctypes version number was changed to 1.0.1.
1369
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001370- Bug #1530559, struct.pack raises TypeError where it used to convert.
1371 Passing float arguments to struct.pack when integers are expected
1372 now triggers a DeprecationWarning.

Neal Norwitza1f10902006-07-12 07:28:29 +00001421
1422Core and builtins
1423-----------------
1424
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001425- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001426 returned a long (see PEP 353).
1427
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001428- Bug #1515471: string.replace() accepts character buffers again.
1429
Neal Norwitz07aadb12006-07-30 06:55:48 +00001430- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1431 This provides the proper warning for struct.pack().
1432 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1433
Neal Norwitz0d62a062006-07-30 06:53:31 +00001434- Patch #1531113: Fix augmented assignment with yield expressions.
1435 Also fix a SystemError when trying to assign to yield expressions.
1436
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001437- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1438 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1439 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1440 excessive filesystem operations during imports.
1441
Tim Petersbc24eee2006-07-27 01:14:53 +00001442- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1443 operations on signed longs that are formally undefined by C.
1444 Unfortunately, at least one compiler now cares about that, so complicated
1445 the code to make that compiler happy again.
1446
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001447- Bug #1524310: Properly report errors from FindNextFile in os.listdir.

1451
Neal Norwitze1fdb322006-07-21 05:32:28 +00001452- Fix some potential crashes found with failmalloc.
1453
Neal Norwitze7563102006-07-17 01:00:16 +00001454- Fix warnings reported by Klocwork's static analysis tool.

Georg Brandl9dceedb2006-07-12 15:31:17 +00001459- Patch #1521179: Python now accepts the standard options ``--help`` and
1460 ``--version`` as well as ``/?`` on Windows.
1461
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001462- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001463 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001464 This means that .pyc files generated before 2.5b3 will be regenerated.

Tim Peters112aad32006-07-19 00:03:19 +00001466- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001467 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001468 new ``sys._current_frames()`` returns a dictionary with one entry,
1469 mapping the faux "thread id" 0 to the current frame.

1475-------
1476
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001477- Correction of patch #1455898: In the mbcs decoder, set final=False
1478 for stream decoder, but final=True for the decode function.
1479
Georg Brandl07fec3a2006-08-01 18:49:24 +00001480- os.urandom no longer masks unrelated exceptions like SystemExit or
1481 KeyboardInterrupt.
1482
Tim Peters4643c2f2006-08-10 22:45:34 +00001483- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001484 shutil.copytree on Windows
1485
Georg Brandle34ac7c2006-07-30 11:07:23 +00001486- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1487 refers to file descriptors, not file objects.
1488
Tim Peterscbdd3502006-09-05 01:47:53 +00001489- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001490 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001491 #1513611, and probably others.
1492
Georg Brandledd9b0d2006-07-29 09:33:26 +00001493- Bug #1441397: The compiler module now recognizes module and function
1494 docstrings correctly as it did in Python 2.4.
1495
Tim Peters6f681472006-07-27 23:44:37 +00001496- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1497 lost that tests are sorted by name before being run. This rarely
1498 matters for well-written tests, but can create baffling symptoms if
1499 side effects from one test to the next affect outcomes. ``DocTestFinder``
1500 has been changed to sort the list of tests it returns.
1501
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001502- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001503 in sync with sys.version_info[:3].

Martin v. Löwis9298eff2006-07-26 12:12:56 +00001505- Bug #978833: Really close underlying socket in _socketobject.close.
1506
Georg Brandldb232dc2006-08-20 13:15:43 +00001507- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1508 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001509
Georg Brandlcf0c1722006-07-26 07:23:32 +00001510- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1511 to recursive calls and call it with the failing package name.
1512
Martin v. Löwis0b483032006-07-25 09:53:12 +00001513- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1514
Georg Brandlc13c34c2006-07-24 14:09:56 +00001515- Patch #1515343: Fix printing of deprecated string exceptions with a
1516 value in the traceback module.
1517
Greg Ward48fae7a2006-07-23 16:05:51 +00001518- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1519
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001520- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1521
Brett Cannoncaebe222006-07-18 04:41:36 +00001522- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1523 argument tuple. For arguments where zero is illegal, the value is forced to
1524 the minimum value that is correct. This is to support an undocumented but
1525 common way people used to fill in inconsequential information in the time
1526 tuple pre-2.4.
1527
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001528- Patch #1220874: Update the binhex module for Mach-O.
1529
Barry Warsawb110bad2006-07-21 14:51:07 +00001530- The email package has improved RFC 2231 support, specifically for
1531 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1532 (name*0=<blah>) parameter continuations. This may change the types of
1533 values returned from email.message.Message.get_param() and friends.
1534 Specifically in some cases where non-encoded continuations were used,
1535 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1536 will just return the string (since non-encoded continuations don't have
1537 charset and language parts).
1538
1539 Also, whereas % values were decoded in all parameter continuations, they are
1540 now only decoded in encoded parameter parts.
1541
Ronald Oussoren3075e162006-07-25 20:28:55 +00001542- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1543
1544- Bug #1517996: IDLE now longer shows the default Tk menu when a
1545 path browser, class browser or debugger is the frontmost window on MacOS X
1546
Barry Warsaw00decd72006-07-27 23:43:15 +00001547- Patch #1520294: Support for getset and member descriptors in types.py,
1548 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1549 of an object against these built-in types and more importantly, for getting
1550 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001553Extension Modules
1554-----------------
1555
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001556- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1557 a socket operation on a socket with a timeout, the exception will be
1558 caught correctly. Previously, the exception was not caught.
1559
Thomas Heller1393d6a2006-07-28 21:43:20 +00001560- Patch #1529514: The _ctypes extension is now compiled on more
1561 openbsd target platforms.
1562
Tim Peters9cab5932006-07-28 00:30:00 +00001563- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1564 a memory leak, affecting pickles and deep copies.
1565
Tim Petersbc24eee2006-07-27 01:14:53 +00001566- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1568
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001569- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1570
Thomas Hellerce049a02006-07-14 17:51:14 +00001571- Patch #1521817: Index range checking on ctypes arrays containing
1572 exactly one element enabled again. This allows iterating over these
1573 arrays, without the need to check the array size before.
1574
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001575- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001576 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001577 /dev/null in certain cases; this is now fixed.
1578
Thomas Heller47d7a062006-07-12 08:43:47 +00001579- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1580 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001581
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001582- Because of a misspelled preprocessor symbol, ctypes was always
1583 compiled without thread support; this is now fixed.
1584
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001585- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1586 methods now allow their database parameter to be None as the
1587 sleepycat API allows.
1588
Matt Flemingec926502006-07-28 11:27:27 +00001589- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1590 bluetooth API compared with Linux and FreeBSD.
1591
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001592Tests
1593-----
1594
1595- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1596 how long the test file should take to play. Now accepts taking 2.93 secs
1597 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1598
Georg Brandl4793aa32006-07-28 18:31:39 +00001599- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1600 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1601 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001608Mac
1609---
1610
1611- PythonLauncher now works correctly when the path to the script contains
1612 characters that are treated specially by the shell (such as quotes).
1613
1614- Bug #1527397: PythonLauncher now launches scripts with the working directory
1615 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001616 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001617 expect.

1626-----------------
1627
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001628- Bug #1441486: The literal representation of -(sys.maxint - 1)
1629 again evaluates to a int object, not a long.
1630
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001631- Bug #1501934: The scope of global variables that are locally assigned
1632 using augmented assignment is now correctly determined.
1633
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001634- Bug #927248: Recursive method-wrapper objects can now safely
1635 be released.
1636
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001637- Bug #1417699: Reject locale-specific decimal point in float()
1638 and atof().
1639
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001640- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1641 omit a default "error" argument for NULL pointer. This allows
1642 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001643
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001644- Bug #1519018: 'as' is now validated properly in import statements.
1645
Neal Norwitz28746ab2006-07-09 22:14:42 +00001646- On 64 bit systems, int literals that use less than 64 bits are
1647 now ints rather than longs.
1648
Neal Norwitzed657552006-07-10 00:04:44 +00001649- Bug #1512814, Fix incorrect lineno's when code at module scope
1650 started after line 256.
1651
Tim Peters32a83612006-07-10 21:08:24 +00001652- New function ``sys._current_frames()`` returns a dict mapping thread
1653 id to topmost thread stack frame. This is for expert use, and is
1654 especially useful for debugging application deadlocks. The functionality
1655 was previously available in Fazal Majid's ``threadframe`` extension
1656 module, but it wasn't possible to do this in a wholly threadsafe way from
1657 an extension.

1666
Tim Peters32a83612006-07-10 21:08:24 +00001667- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001668 environment variable to be set in order to the SDK environment
1669 for finding the compiler, include files, etc.

1674
Thomas Woutersadd19112006-07-05 11:03:49 +00001675- string.Template() now correctly handles tuple-values. Previously,
1676 multi-value tuples would raise an exception and single-value tuples would
1677 be treated as the value they contain, instead.
1678
Martin v. Löwisede77f52006-07-03 13:01:35 +00001679- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1681
Martin v. Löwis45482392006-07-03 12:28:58 +00001682- Bug #1267547: Put proper recursive setup.py call into the
1683 spec file generated by bdist_rpm.
1684
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001685- Bug #1514693: Update turtle's heading when switching between
1686 degrees and radians.
1687
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001688- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001689 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001690
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001691- Bug #1514703: Only setup canvas window in turtle when the canvas
1692 is created.
1693
Martin v. Löwis7596e832006-07-01 15:33:37 +00001694- Bug #1513223: .close() of a _socketobj now releases the underlying
1695 socket again, which then gets closed as it becomes unreferenced.
1696
Fred Drake10497c82006-06-29 02:57:48 +00001697- Bug #1504333: Make sgmllib support angle brackets in quoted
1698 attribute values.
1699
1700- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1701 sgmllib ('[' and ']' were not accepted).
1702
Georg Brandl1be63af2006-06-28 20:23:25 +00001703- Fix a bug in the turtle module's end_fill function.
1704
Brett Cannon53ab5b72006-06-22 16:49:14 +00001705- Bug #1510580: The 'warnings' module improperly required that a Warning
1706 category be either a types.ClassType and a subclass of Warning. The proper
1707 check is just that it is a subclass with Warning as the documentation states.
1708
Georg Brandlad29e632006-06-21 17:45:17 +00001709- The compiler module now correctly compiles the new try-except-finally
1710 statement (bug #1509132).
1711
Neal Norwitz60373cd2006-06-22 06:30:50 +00001712- The wsgiref package is now installed properly on Unix.
1713
Vinay Sajip28e57612006-07-01 10:45:20 +00001714- A bug was fixed in logging.config.fileConfig() which caused a crash on
1715 shutdown when fileConfig() was called multiple times.
1716
Gerhard Häring762fbd32006-07-02 17:48:30 +00001717- The sqlite3 module did cut off data from the SQLite database at the first
1718 null character before sending it to a custom converter. This has been fixed
1719 now.

1722-----------------
1723
Tim Peters112aad32006-07-19 00:03:19 +00001724- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1725 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1726 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001727
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001728- Assigning None to pointer type fields in ctypes structures possible
1729 overwrote the wrong fields, this is fixed now.
1730
1731- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1732 on non-Windows platforms.
1733
1734- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1735 integer or long, without range checking.
1736
1737- Patch #1517790: It is now possible to use custom objects in the ctypes
1738 foreign function argtypes sequence as long as they provide a from_param
1739 method, no longer is it required that the object is a ctypes type.
1740
1741- The '_ctypes' extension module now works when Python is configured
1742 with the --without-threads option.
1743
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001744- Bug #1513646: os.access on Windows now correctly determines write

1759
Tim Peters32a83612006-07-10 21:08:24 +00001760- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001761 Previously, the slight difference could cause compilation errors of the
1762 'zlib' module on systems with more than one version of zlib.
1763
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001764- The MSI compileall step was fixed to also support a TARGETDIR

Nick Coghlanc649ec52006-05-29 12:43:05 +00001790What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001791================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001792
Anthony Baxterd1136802006-06-19 12:04:15 +00001793*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001794
1795Core and builtins
1796-----------------
1797
Georg Brandla56b9152006-06-19 06:35:54 +00001798- Patch #1507676: Error messages returned by invalid abstract object operations
1799 (such as iterating over an integer) have been improved and now include the
1800 type of the offending object to help with debugging.
1801
Brett Cannonea3912b2006-06-13 21:46:41 +00001802- Bug #992017: A classic class that defined a __coerce__() method that returned
1803 its arguments swapped would infinitely recurse and segfault the interpreter.
1804
Neal Norwitz909eb122006-06-12 02:13:21 +00001805- Fix the socket tests so they can be run concurrently.
1806
Neal Norwitzb9845e72006-06-12 02:11:18 +00001807- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001808 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001809
Brett Cannon22565aa2006-06-09 22:31:23 +00001810- Bug #532646: object.__call__() will continue looking for the __call__
1811 attribute on objects until one without one is found. This leads to recursion
1812 when you take a class and set its __call__ attribute to an instance of the
1813 class. Originally fixed for classic classes, but this fix is for new-style.
1814 Removes the infinite_rec_3 crasher.
1815
Georg Brandl24250812006-06-09 18:45:48 +00001816- The string and unicode methods startswith() and endswith() now accept
1817 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1818
Brett Cannonde3b0522006-06-08 17:00:45 +00001819- Buffer objects, at the C level, never used the char buffer
1820 implementation even when the char buffer for the wrapped object was
1821 explicitly requested (originally returned the read or write buffer).
1822 Now a TypeError is raised if the char buffer is not present but is
1823 requested.
1824
Georg Brandlddbaa662006-06-04 21:56:52 +00001825- Patch #1346214: Statements like "if 0: suite" are now again optimized
1826 away like they were in Python 2.4.
1827
Georg Brandlb7c8f542006-05-27 12:30:25 +00001828- Builtin exceptions are now full-blown new-style classes instead of
1829 instances pretending to be classes, which speeds up exception handling
1830 by about 80% in comparison to 2.5a2.
1831
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001832- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1833 Unicode 4.1.
1834
Georg Brandlf4ef1162006-05-26 18:03:31 +00001835- Patch #921466: sys.path_importer_cache is now used to cache valid and
1836 invalid file paths for the built-in import machinery which leads to
1837 fewer open calls on startup.
1838
Tim Peters696cf432006-05-24 21:10:40 +00001839- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1840 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1841 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1842 the number of input digits (it was and remains linear-time for bases
1843 2, 4, 8, 16 and 32).
1844
Tim Petersb713ec22006-05-23 18:45:30 +00001845- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1846 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1847 an integer close to ``sys.maxint``. This was repaired by patch
1848 #1335972, which also gives a nice speedup.
1849
Richard Jonescebbefc2006-05-23 18:28:17 +00001850- Patch #1337051: reduced size of frame objects.
1851
1852- PyErr_NewException now accepts a tuple of base classes as its
1853 "base" parameter.
1854
Richard Jones7c88dcc2006-05-23 10:37:38 +00001855- Patch #876206: function call speedup by retaining allocated frame
1856 objects.
1857
Georg Brandl7b90e162006-05-18 07:01:27 +00001858- Bug #1462152: file() now checks more thoroughly for invalid mode
1859 strings and removes a possible "U" before passing the mode to the
1860 C library function.
1861
Neal Norwitz1004a532006-05-15 07:17:23 +00001862- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1863
Neal Norwitz373f0a72006-05-15 07:04:36 +00001864- Bug #1487966: Fix SystemError with conditional expression in assignment
1865
Martin v. Löwis879768d2006-05-11 13:28:43 +00001866- WindowsError now has two error code attributes: errno, which carries
1867 the error values from errno.h, and winerror, which carries the error
1868 values from winerror.h. Previous versions put the winerror.h values
1869 (from GetLastError()) into the errno attribute.
1870
Martin v. Löwis77736712006-05-04 05:51:03 +00001871- Patch #1475845: Raise IndentationError for unexpected indent.
1872
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001873- Patch #1479181: split open() and file() from being aliases for each other.
1874
Tim Peters44bd9862006-06-01 13:49:23 +00001875- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1876 methods were always silently ignored by dictionaries when comparing keys.
1877 They are now passed through (except when using the C API function
1878 ``PyDict_GetItem()``, whose semantics did not change).
1879
1880- Bug #1456209: In some obscure cases it was possible for a class with a
1881 custom ``__eq__()`` method to confuse dict internals when class instances
1882 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1883 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001885Extension Modules
1886-----------------
1887
Trent Mick960a3f82006-06-28 20:30:41 +00001888- Bug #1295808: expat symbols should be namespaced in pyexpat
1889
1890- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1891
Brett Cannon6ee7d012006-06-08 16:23:04 +00001892- Change binascii.hexlify to accept a read-only buffer instead of only a char
1893 buffer and actually follow its documentation.
1894
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001895- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1896
Nick Coghlanc649ec52006-05-29 12:43:05 +00001897- Patch #1478788 (modified version): The functional extension module has
1898 been renamed to _functools and a functools Python wrapper module added.
1899 This provides a home for additional function related utilities that are
1900 not specifically about functional programming. See PEP 309.
1901
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001902- Patch #1493701: performance enhancements for struct module.
1903
Georg Brandl378d5922006-05-17 14:26:50 +00001904- Patch #1490224: time.altzone is now set correctly on Cygwin.
1905
Georg Brandl8d3342b2006-05-16 07:38:27 +00001906- Patch #1435422: zlib's compress and decompress objects now have a
1907 copy() method.
1908
Andrew MacIntyre92913322006-06-13 15:04:24 +00001909- Patch #1454481: thread stack size is now tunable at runtime for thread
1910 enabled builds on Windows and systems with Posix threads support.
1911
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001912- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1913 (up to the system limit of 32K characters).
1914
1915- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1916 As a result, these functions now raise WindowsError instead of OSError.
1917
Tim Peters7a822da2006-05-25 21:50:17 +00001918- ``time.clock()`` on Win64 should use the high-performance Windows
1919 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1920 Windows platforms).
1921
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001922- Calling Tk_Init twice is refused if the first call failed as that
1923 may deadlock.
1924
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001925- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1926 accept it without potentially using an uninitialized pointer.
1927
1928- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1929 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1930 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001931
Gregory P. Smith372b5832006-06-05 18:48:21 +00001932- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001933 [pybsddb project SF patch number 1466734]
1934
Gregory P. Smith372b5832006-06-05 18:48:21 +00001935- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1936 parameter is supplied. [SF pybsddb bug #1477863]
1937
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001938- bsddb: the __len__ method of a DB object has been fixed to return correct
1939 results. It could previously incorrectly return 0 in some cases.
1940 Fixes SF bug 1493322 (pybsddb bug 1184012).
1941
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001942- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1943 aborts the db transaction safely when a modifier callback fails.
1944 Fixes SF python patch/bug #1408584.
1945
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001946- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001947 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001948 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1949 database calls that would previously deadlock. [SF python bug #775414]
1950
Vinay Sajip28e57612006-07-01 10:45:20 +00001951- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001952
Walter Dörwald4994d952006-06-19 08:07:50 +00001953- Patch #1506645: add Python wrappers for the curses functions
1954 is_term_resized, resize_term and resizeterm.

1957-------
1958
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001959- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1960 functions.
1961
Martin v. Löwis3798da02006-06-17 18:44:27 +00001962- Patch #812986: Update turtle output even if not tracing.
1963
Vinay Sajip28e57612006-07-01 10:45:20 +00001964- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001965 Tkinter.BaseWidget.
1966
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001967- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1968
Martin v. Löwis337487e2006-06-17 09:15:14 +00001969- Patch #763580: Add name and value arguments to Tkinter variable
1970 classes.
1971
Georg Brandl83cc0d02006-06-14 08:50:03 +00001972- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1973 mime.types file for determining MIME types.
1974
Georg Brandl2605ca82006-06-14 06:08:31 +00001975- Bug #1339007: Shelf objects now don't raise an exception in their
1976 __del__ method when initialization failed.
1977
Martin v. Löwisd8251432006-06-14 05:21:04 +00001978- Patch #1455898: The MBCS codec now supports the incremental mode for
1979 double-byte encodings.
1980
Tim Peters43898b42006-06-14 04:09:25 +00001981- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1982 guarantee that adjacent triples in the return list always describe
1983 non-adjacent blocks. Previously, a pair of matching blocks could end
1984 up being described by multiple adjacent triples that formed a partition
1985 of the matching pair.
1986
Greg Ward0e0c9f42006-06-11 16:24:11 +00001987- Bug #1498146: fix optparse to handle Unicode strings in option help,
1988 description, and epilog.
1989
Greg Wardd1c797e2006-06-11 14:42:41 +00001990- Bug #1366250: minor optparse documentation error.
1991
Greg Ward7f547402006-06-11 00:40:49 +00001992- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1993 clarify docs.
1994
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001995- The wsgiref package has been added to the standard library.
1996
Nick Coghlan676725d2006-06-08 13:54:49 +00001997- The functions update_wrapper() and wraps() have been added to the functools
1998 module. These make it easier to copy relevant metadata from the original
1999 function when writing wrapper functions.
2000
Tim Petersd6a9eef2006-06-05 01:48:21 +00002001- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2002 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002003
Martin v. Löwis3f767792006-06-04 19:36:28 +00002004- Patch #1359618: Speed up charmap encoder by using a trie structure
2005 for lookup.
2006
Tim Petersd609b1a2006-06-02 23:22:51 +00002007- The functions in the ``pprint`` module now sort dictionaries by key
2008 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2009 if and only if its display required more than one line, although that
2010 wasn't documented. The new behavior increases predictability; e.g.,
2011 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2012
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002013- Patch #1497027: try HTTP digest auth before basic auth in urllib2
2014 (thanks for J. J. Lee).
2015
Georg Brandl2b330372006-05-28 20:23:12 +00002016- Patch #1496206: improve urllib2 handling of passwords with respect to
2017 default HTTP and HTTPS ports.
2018
George Yoshidaf3c65de2006-05-28 16:39:09 +00002019- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
2020
Bob Ippolito7298f272006-05-23 18:43:47 +00002021- Patch #1281707: speed up gzip.readline.
2022
Georg Brandlb89316f2006-05-17 15:51:16 +00002023- Patch #1180296: Two new functions were added to the locale module:
2024 format_string() to get the effect of "format % items" but locale-aware,
2025 and currency() to format a monetary number with currency sign.
2026
Georg Brandle3a25832006-05-17 14:56:04 +00002027- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2028 and several features added, such as speed and geometry control.
2029
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002030- Patch #1488881: add support for external file objects in bz2 compressed
2031 tarfiles.
2032
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002033- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2034 stdout arguments, making it possible to redirect input and output
2035 for remote debugging.
2036
2037- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2038 a couple of issues, notably handling of long file names using the
2039 GNU LONGNAME extension.
2040
2041- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2042 new flag when ``name`` is already the name of an option flag.
2043
2044- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2045 package.
2046
2047- Patch #1472854: make the rlcompleter.Completer class usable on non-
2048 UNIX platforms.
2049
2050- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
2051
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00002052- Bug #1472827: correctly escape newlines and tabs in attribute values in

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002083What's New in Python 2.5 alpha 2?
2084=================================
2085
2086*Release date: 27-APR-2006*
2087
2088Core and builtins
2089-----------------
2090
Thomas Heller1b046642006-04-18 18:51:06 +00002091- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2092 by converting these apis from macros into exported functions again:
2093
2094 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2095 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2096 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2097 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2098 PyRun_String Py_CompileString
2099
Martin v. Löwis45294a92006-04-18 06:24:08 +00002100- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2101
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002102- All uses of PyStructSequence_InitType have been changed to initialize
2103 the type objects only once, even if the interpreter is initialized
2104 multiple times.
2105
Neal Norwitz61546162006-04-14 05:20:28 +00002106- Bug #1454485, array.array('u') could crash the interpreter. This was
2107 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2108 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2109
2110- Py_UNICODE is unsigned. It was always documented as unsigned, but
2111 due to a bug had a signed value in previous versions.
2112
Tim Peters3a5e8b12006-04-11 01:44:07 +00002113- Patch #837242: ``id()`` of any Python object always gives a positive
2114 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2115 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002116 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002117 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002118
Tim Peters3a5e8b12006-04-11 01:44:07 +00002119 def __hash__(self):
2120 return id(self) # WRONG
2121
2122 because a hash result must be a (short) Python int but it was always
2123 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002124 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002125 was always usable as a hash value before this patch. That's no longer
2126 necessarily so.
2127
2128- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002129 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002130 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002131 #1454844)
2132
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002133- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2134 involving generators that have paused outside of any ``try`` or ``with``
2135 blocks. (In 2.5a1, a paused generator that was part of a reference
2136 cycle could not be garbage collected, regardless of whether it was
2137 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00002138
Anthony Baxter51bcb682006-04-05 14:51:42 +00002139Extension Modules
2140-----------------
2141
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00002142- Patch #1191065: Fix preprocessor problems on systems where recvfrom
2143 is a macro.
2144
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002145- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2146 fails with an error condition.
2147
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002148- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2149
2150- Bug #1117761: bsddb.*open() no longer raises an exception when using
2151 the cachesize parameter.
2152
2153- Bug #1149413: bsddb.*open() no longer raises an exception when using
2154 a temporary db (file=None) with the 'n' flag to truncate on open.
2155
2156- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2157 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002158
Armin Rigoa9017c32006-04-19 11:50:27 +00002159- Patch #1062014: AF_UNIX sockets under Linux have a special
2160 abstract namespace that is now fully supported.
2161
Anthony Baxter51bcb682006-04-05 14:51:42 +00002162Library
2163-------
2164
Peter Astrand7d1d4362006-07-14 14:04:45 +00002165- Bug #1223937: subprocess.CalledProcessError reports the exit status
2166 of the process using the returncode attribute, instead of
2167 abusing errno.
2168
Tim Peters711bf302006-04-25 03:31:36 +00002169- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2170 a doctest to be skipped (the code is not run, and the expected output
2171 or exception is ignored).
2172
Nick Coghlanda2268f2006-04-24 04:37:15 +00002173- Fixed contextlib.nested to cope with exceptions being raised and
2174 caught inside exit handlers.
2175
Greg Wardab05edc2006-04-23 03:47:58 +00002176- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2177 hex, octal, or binary; add ``append_const`` action; keep going if
2178 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2179 added ``epilog`` for better help generation).
2180
Tim Peters21fbd572006-04-21 21:18:10 +00002181- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2182 called from a thread spawned as a side effect of importing a module.
2183
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002184- The pydoc module now supports documenting packages contained in
2185 .zip or .egg files.
2186
2187- The pkgutil module now has several new utility functions, such
2188 as ``walk_packages()`` to support working with packages that are either
2189 in the filesystem or zip files.
2190
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002191- The mailbox module can now modify and delete messages from
2192 mailboxes, in addition to simply reading them. Thanks to Gregory
2193 K. Johnson for writing the code, and to the 2005 Google Summer of
2194 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002195
Tim Petersc7605f22006-04-17 21:12:33 +00002196- The ``__del__`` method of class ``local`` in module ``_threading_local``
2197 returned before accomplishing any of its intended cleanup.
2198
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002199- Patch #790710: Add breakpoint command lists in pdb.
2200
Martin v. Löwis0db2a982006-04-16 20:55:38 +00002201- Patch #1063914: Add Tkinter.Misc.clipboard_get().
2202
Martin v. Löwis4b501e62006-04-15 08:41:11 +00002203- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
2204
Anthony Baxtere29002c2006-04-12 12:07:31 +00002205- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2206 Windows. Bug #1469163.
2207
Phillip J. Eby47032112006-04-11 01:07:43 +00002208- The warnings, linecache, inspect, traceback, site, and doctest modules
2209 were updated to work correctly with modules imported from zipfiles or
2210 via other PEP 302 __loader__ objects.
2211
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002212- Patch #1467770: Reduce usage of subprocess._active to processes which
2213 the application hasn't waited on.
2214
Martin v. Löwisb04dee92006-04-10 08:34:21 +00002215- Patch #1462222: Fix Tix.Grid.
2216
Neal Norwitza31bf182006-04-09 03:35:43 +00002217- Fix exception when doing glob.glob('anything*/')
2218
Skip Montanaro262fb922006-04-21 02:31:07 +00002219- The pstats.Stats class accepts an optional stream keyword argument to
2220 direct output to an alternate file-like object.
2221
Anthony Baxter51bcb682006-04-05 14:51:42 +00002222Build
2223-----
2224
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002225- The Makefile now has a reindent target, which runs reindent.py on
2226 the library.
2227
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002228- Patch #1470875: Building Python with MS Free Compiler
2229
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002230- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002231
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002232- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2233 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002234 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002235 CXX from --with-cxx-main, see description in README.
2236
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002237- Patch #1429775: Link extension modules with the shared libpython.
2238
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002239- Fixed a libffi build problem on MIPS systems.
2240
Tim Peters8931ff12006-05-13 23:28:20 +00002241- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2242 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2243 and "%zu" for unsigned integers of type ``size_t``.
2244
Anthony Baxter51bcb682006-04-05 14:51:42 +00002245Tests
2246-----
2247
Nick Coghlanda2268f2006-04-24 04:37:15 +00002248- test_contextlib now checks contextlib.nested can cope with exceptions
2249 being raised and caught inside exit handlers.
2250
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002251- test_cmd_line now checks operation of the -m and -c command switches
2252
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002253- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2254 it separately and by hand. It also wasn't cleaning up its changes to
2255 the current Decimal context.
2256
Thomas Woutersabd08882006-04-26 15:53:30 +00002257- regrtest.py now has a -M option to run tests that test the new limits of
2258 containers, on 64-bit architectures. Running these tests is only sensible
2259 on 64-bit machines with more than two gigabytes of memory. The argument
2260 passed is the maximum amount of memory for the tests to use.

2269-------------
2270
Tim Petersb06d28c2006-05-12 01:57:59 +00002271- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2272
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002273- PEP 343: Added Context Types section to the library reference
2274 and attempted to bring other PEP 343 related documentation into
2275 line with the implementation and/or python-dev discussions.
2276
Tim Peters8dc73d22006-04-24 02:03:16 +00002277- Bug #1337990: clarified that ``doctest`` does not support examples
2278 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002281What's New in Python 2.5 alpha 1?
2282=================================
2283
Anthony Baxterebed3f62006-04-03 15:03:44 +00002284*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002285
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002286Core and builtins
2287-----------------
2288
Nick Coghlan43832302006-04-23 17:04:07 +00002289- PEP 338: -m command line switch now delegates to runpy.run_module
2290 allowing it to support modules in packages and zipfiles
2291
Martin v. Löwisc661b882006-04-20 04:54:23 +00002292- On Windows, .DLL is not an accepted file name extension for
2293 extension modules anymore; extensions are only found if they
2294 end in .PYD.
2295
Martin v. Löwisea62d252006-04-03 10:56:49 +00002296- Bug #1421664: sys.stderr.encoding is now set to the same value as
2297 sys.stdout.encoding.
2298
Neal Norwitz92e212f2006-04-03 04:48:37 +00002299- __import__ accepts keyword arguments.
2300
Georg Brandlccadf842006-03-31 18:54:53 +00002301- Patch #1460496: round() now accepts keyword arguments.
2302
Anthony Baxter262c00a2006-03-30 10:53:17 +00002303- Fixed bug #1459029 - unicode reprs were double-escaped.
2304
Hye-Shik Changd478f342006-03-23 12:32:36 +00002305- Patch #1396919: The system scope threads are reenabled on FreeBSD
2306 5.4 and later versions.
2307
Neal Norwitze98ccf62006-03-23 05:39:47 +00002308- Bug #1115379: Compiling a Unicode string with an encoding declaration
2309 now gives a SyntaxError.
2310
Georg Brandlabd1ff82006-03-18 07:59:59 +00002311- Previously, Python code had no easy way to access the contents of a
2312 cell object. Now, a ``cell_contents`` attribute has been added
2313 (closes patch #1170323).
2314
Tim Peterscf79aac2006-03-16 01:14:46 +00002315- Patch #1123430: Python's small-object allocator now returns an arena to
2316 the system ``free()`` when all memory within an arena becomes unused
2317 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2318 freed. Some applications will see a drop in virtual memory size now,
2319 especially long-running applications that, from time to time, temporarily
2320 use a large number of small objects. Note that when Python returns an
2321 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002322 platform C library will in turn return that memory to the operating system.
2323 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002324 appears to be effective at least on Microsoft C and gcc-based systems.
2325 Thanks to Evan Jones for hard work and patience.
2326
Georg Brandl533ff6f2006-03-08 18:09:27 +00002327- Patch #1434038: property() now uses the getter's docstring if there is
2328 no "doc" argument given. This makes it possible to legitimately use
2329 property() as a decorator to produce a read-only property.
2330
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002331- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2332 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2333 of requiring an int or long in slicing and a few other contexts, enabling
2334 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2335
Neal Norwitz995acdf2006-03-07 05:01:00 +00002336- Fixed various bugs reported by Coverity's Prevent tool.
2337
Brett Cannonbf364092006-03-01 04:25:17 +00002338- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2339 new exception base class, BaseException, which has a new message attribute.
2340 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2341 Raising a string exception now raises a DeprecationWarning.
2342
Thomas Woutersfb609f42006-02-28 16:37:25 +00002343- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2344 explicitly relative, using 'from .module import name' to mean 'from the same
2345 package as this module is in. Imports without dots still default to the
2346 old relative-then-absolute, unless 'from __future__ import
2347 absolute_import' is used.
2348
Brett Cannona7446e32006-02-27 23:39:10 +00002349- Properly check if 'warnings' raises an exception (usually when a filter set
2350 to "error" is triggered) when raising a warning for raising string
2351 exceptions.
2352
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002353- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002354 The name was removed from Include/code.h.
2355
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002356- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002357
Guido van Rossum1968ad32006-02-25 22:38:04 +00002358- Patch 1433928:
2359 - The copy module now "copies" function objects (as atomic objects).
2360 - dict.__getitem__ now looks for a __missing__ hook before raising
2361 KeyError.
2362
Tim Peters84ef21c2006-02-28 20:39:06 +00002363- PEP 343: with statement implemented. Needs ``from __future__ import
2364 with_statement``. Use of 'with' as a variable will generate a warning.
2365 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002366 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002367 The following objects have __context__ methods:
2368 - The built-in file type.
2369 - The thread.LockType type.
2370 - The following types defined by the threading module:
2371 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2372 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002373
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002374- Fix the encodings package codec search function to only search
2375 inside its own package. Fixes problem reported in patch #1433198.
2376
2377 Note: Codec packages should implement and register their own
2378 codec search function. PEP 100 has the details.
2379
Tim Peters9ea89d22006-06-04 03:26:02 +00002380- PEP 353: Using ``Py_ssize_t`` as the index type.
2381
2382- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2383 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2384 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2385 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2386 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002387
Neal Norwitzfc76d632006-01-10 06:03:13 +00002388- Patch #1400181, fix unicode string formatting to not use the locale.
2389 This is how string objects work. u'%f' could use , instead of .
2390 for the decimal point. Now both strings and unicode always use periods.
2391
Neal Norwitz671b9e32006-01-09 07:07:12 +00002392- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2393 configure would break checking curses.h.
2394
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002395- Bug #959576: The pwd module is now builtin. This allows Python to be
2396 built on UNIX platforms without $HOME set.
2397
Neal Norwitzc10978f2005-12-19 06:07:16 +00002398- Bug #1072182, fix some potential problems if characters are signed.
2399
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002400- Bug #889500, fix line number on SyntaxWarning for global declarations.
2401
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002402- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2403
Neal Norwitze7214a12005-12-18 05:03:17 +00002404- Support for converting hex strings to floats no longer works.
2405 This was not portable. float('0x3') now raises a ValueError.
2406
Barry Warsaw2a38a862005-12-18 01:27:35 +00002407- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002408 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002409 is now displayed in interactive prompt banner.
2410
Georg Brandlfa166682005-12-17 21:45:17 +00002411- Implementation of PEP 341 - Unification of try/except and try/finally.
2412 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002413 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002414
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002415- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2416 now encodes backslash correctly.
2417
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002418- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2419
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002420- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002421 and long longs.
2422
Neal Norwitz67715f02005-11-09 06:59:35 +00002423- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002424 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002425 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002426
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002427- Replaced most Unicode charmap codecs with new ones using the
2428 new Unicode translate string feature in the builtin charmap
2429 codec; the codecs were created from the mapping tables available
2430 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2431 encodings now include a mapping for the Apple logo)
2432
Tim Peterse3547fd2005-12-16 23:13:57 +00002433- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002434
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002435- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002436
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002437- A new AST parser implementation was completed. The abstract
2438 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002439 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002440
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002441- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002442 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2443
Neal Norwitz708e51a2005-10-03 04:48:15 +00002444- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2445
Neal Norwitz11bd1192005-10-03 00:54:56 +00002446- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2447 Provide a warning when a directory is passed on the command line.
2448
Neal Norwitz40d37812005-10-02 01:48:49 +00002449- Fix segfault with invalid coding.
2450
2451- SF bug #772896: unknown encoding results in MemoryError.
2452
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002453- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002454 supported a __len__() method which evaluated to False when the iterator
2455 was empty.
2456
Guido van Rossum630db602005-09-20 18:49:54 +00002457- On 64-bit platforms, when __len__() returns a value that cannot be
2458 represented as a C int, raise OverflowError.
2459
Skip Montanarof8948ca2005-09-19 03:54:46 +00002460- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002461 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002462
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002463- SF bug #893549: parsing keyword arguments was broken with a few format
2464 codes.
2465
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002466- Changes donated by Elemental Security to make it work on AIX 5.3
2467 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2468 bug #105470: test_pwd fails on 64bit system (Opteron).
2469
Guido van Rossum539c6622005-09-14 17:49:54 +00002470- Changes donated by Elemental Security to make it work on HP-UX 11 on
2471 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2472
Georg Brandl4550b8d2005-08-26 06:43:52 +00002473- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002474 (fixes bug #1119418).
2475
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002476- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2477
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002478- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2479 exceptions that cause a function to exit.
2480
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002481- The implementation of set() and frozenset() was revised to use its
2482 own internal data structure. Memory consumption is reduced by 1/3
2483 and there are modest speed-ups as well. The API is unchanged.
2484
Tim Petersde7990b2005-07-17 23:45:23 +00002485- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2486
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002487- SF bug #1229429: PyObject_CallMethod failed to decrement some
2488 reference counts in some error exit cases.
2489
Tim Petersecc6e6a2005-07-10 22:30:55 +00002490- SF bug #1185883: Python's small-object memory allocator took over
2491 a block managed by the platform C library whenever a realloc specified
2492 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002493 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002494 portable way to copy data from the C-managed block into Python's
2495 small-object space without risking a memory fault. Python's small-object
2496 realloc now leaves such blocks under the control of the platform C
2497 realloc.
2498
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002499- SF bug #1232517: An overflow error was not detected properly when
2500 attempting to convert a large float to an int in os.utime().
2501
Raymond Hettinger3296e692005-06-29 23:29:56 +00002502- SF bug #1224347: hex longs now print with lowercase letters just
2503 like their int counterparts.
2504
Michael W. Hudson188d4362005-06-20 16:52:57 +00002505- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2506 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2507 interpreter states; back out that fix and do a better job (see
2508 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2509 for a longer write-up of the problem).
2510
Michael W. Hudsondf888462005-06-03 14:41:55 +00002511- SF patch #1180995: marshal now uses a binary format by default when
2512 serializing floats.
2513
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002514- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2515 the routines that promise to produce IEEE 754 binary representations
2516 of floats now simply copy bytes around.
2517
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002518- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2519 278.
2520
Brett Cannonc3647ac2005-04-26 03:45:26 +00002521- patch #1109424: int, long, float, complex, and unicode now check for the
2522 proper magic slot for type conversions when subclassed. Previously the
2523 magic slot was ignored during conversion. Semantics now match the way
2524 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002525 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002526 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002527 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002528
Barry Warsawc8d907c2005-04-19 23:43:40 +00002529- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2530 NULL, now raise an AttributeError when attempting to set or delete the
2531 attribute. Previously a TypeError was raised, but this was inconsistent
2532 with the equivalent pure-Python implementation.
2533
Michael W. Hudson774479c2005-04-18 08:46:17 +00002534- It is now safe to call PyGILState_Release() before
2535 PyEval_InitThreads() (note that if there is reason to believe there
2536 are multiple threads around you still must call PyEval_InitThreads()
2537 before using the Python API; this fix is for extension modules that
2538 have no way of knowing if Python is multi-threaded yet).
2539
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002540- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2541 disabled caused a crash.
2542
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002543- Bug #1165306: instancemethod_new allowed the creation of a method
2544 with im_class == im_self == NULL, which caused a crash when called.
2545
Tim Petersecc6e6a2005-07-10 22:30:55 +00002546- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002547 fixes the crash seen in bug #1165761
2548
Raymond Hettinger96229b12005-03-11 06:49:40 +00002549- Added two new builtins, any() and all().
2550
Brett Cannon409d8f22005-03-05 06:47:57 +00002551- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002552 (e.g., ``class C(): pass`` is no longer a syntax error).
2553 Patch #1176012 added support to the 'parser' module and 'compiler' package
2554 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002555
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002556- Patch #1115086: Support PY_LONGLONG in structmember.
2557
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002558- Bug #1155938: new style classes did not check that __init__() was
2559 returning None.
2560
Tim Petersecc6e6a2005-07-10 22:30:55 +00002561- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002562 ('\') with a specific error message.
2563
Martin v. Löwisff232d72005-03-03 09:24:38 +00002564- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2565
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002566- Bug #1124295: the __name__ attribute of file objects was
2567 inadvertently made inaccessible in restricted mode.
2568
Tim Petersecc6e6a2005-07-10 22:30:55 +00002569- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002570 an ferror() call.
2571
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002572- min() and max() now support key= arguments with the same meaning as in
2573 list.sort().
2574
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002575- The peephole optimizer now performs simple constant folding in expressions:
2576 (2+3) --> (5).
2577
Raymond Hettingera422c342005-01-11 03:03:27 +00002578- set and frozenset objects can now be marshalled. SF #1098985.
2579
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002580- Bug #1077106: Poor argument checking could cause memory corruption
2581 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002582
Jeremy Hyltonab630502005-02-04 18:44:06 +00002583- The parser did not complain about future statements in illegal
2584 positions. It once again reports a syntax error if a future
2585 statement occurs after anything other than a doc string.
2586
Neil Schemenauercf52c072005-08-12 17:34:58 +00002587- Change the %s format specifier for str objects so that it returns a
2588 unicode instance if the argument is not an instance of basestring and
2589 calling __str__ on the argument returns a unicode instance.
2590
Tim Petersf4e69282006-02-27 17:15:31 +00002591- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2592 current thread state when the auto-GIL-state machinery knows about
2593 it (since the thread state is being deleted, continuing to remember it
2594 can't help, but can hurt if another thread happens to get created with
2595 the same thread id).
2596
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002597Extension Modules
2598-----------------
2599
Georg Brandl43f08a82006-03-31 18:01:16 +00002600- Patch #1380952: fix SSL objects timing out on consecutive read()s
2601
Neal Norwitz05a45592006-03-20 06:30:08 +00002602- Patch #1309579: wait3 and wait4 were added to the posix module.
2603

2773
Raymond Hettingerb2594052004-12-05 09:25:51 +00002774- itertools.islice() now accepts None for the start and step arguments.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002787- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2788 been renamed to have only a single underscore prefix. This was done to
2789 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002790
Nick Coghlan43832302006-04-23 17:04:07 +00002791- PEP 338: new module runpy defines a run_module function to support
2792 executing modules which provide access to source code or a code object
2793 via the PEP 302 import mechanisms.
2794
Anthony Baxter93f5b932006-04-03 08:05:07 +00002795- The email module's parsedate_tz function now sets the daylight savings

2803 in attribute values.
2804
Anthony Baxterc51ee692006-04-01 00:57:31 +00002805- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002806 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002807 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002808 module will not be built.
2809
Tim Petersc17976e2006-04-01 00:26:53 +00002810- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2811 aren't officially supported here, and trying to use them will probably
2812 raise an exception some day. But dicts have been allowed, and "mostly
2813 worked", so support for them won't go away without warning.
2814
Georg Brandl338ef7d2006-03-31 18:42:16 +00002815- Bug #1445068: getpass.getpass() can now be given an explicit stream
2816 argument to specify where to write the prompt.
2817

2833
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002834- email 4.0 package now integrated. This is largely the same as the email 3.0
2835 package that was included in Python 2.3, except that PEP 8 module names are
2836 now used (e.g. mail.message instead of email.Message). The MIME classes
2837 have been moved to a subpackage (e.g. email.mime.text instead of
2838 email.MIMEText). The old names are still supported for now. Several
2839 deprecated Message methods have been removed and lots of bugs have been
2840 fixed. More details can be found in the email package documentation.
2841
Walter Dörwald40108c92006-03-27 08:15:44 +00002842- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2843 (a subclass of tuple) that provides incremental decoders and encoders
2844 (a way to use stateful codecs without the stream API). Python functions
2845 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2846 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2847 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002849- Patch #1359365: Calling next() on a closed StringIO.String object raises
2850 a ValueError instead of a StopIteration now (like file and cString.String do).
2851 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2852 called before (like file and StringIO.StringIO do).

2930
2931 "The consensus of researchers in this area (at least as
2932 expressed at the NIST Hash Function Workshop 10/31/05),
2933 is that SHA-256 is a good choice for the time being, but
2934 that research should continue, and other alternatives may
2935 arise from this research. The larger SHA's also seem OK."

3124 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003125 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003126 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003127 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3128 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003129 + reader now allows \r characters to be quoted (previously it only allowed
3130 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003131 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003132 + Dialect classes passed to the module are no longer instantiated by
3133 the module before being parsed (the former validation scheme required
3134 this, but the mechanism was unreliable).
3135 + The dialect registry now contains instances of the internal
3136 C-coded dialect type, rather than references to python objects.
3137 + the internal c-coded dialect type is now immutable.
3138 + register_dialect now accepts the same keyword dialect specifications
3139 as the reader and writer, allowing the user to register dialects
3140 without first creating a dialect class.
3141 + a configurable limit to the size of parsed fields has been added -
3142 previously, an unmatched quote character could result in the entire
3143 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003144 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003145 the parser field size limit (returning the former limit). The initial
3146 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003147 + A line_num attribute has been added to the reader object, which tracks
3148 the number of lines read from the source iterator. This is not
3149 the same as the number of records returned, as records can span
3150 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003151 + reader and writer objects were not being registered with the cyclic-GC.
3152 This has been fixed.
3153
Brett Cannone6539c42005-01-08 02:43:53 +00003154- _DummyThread objects in the threading module now delete self.__block that is
3155 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3156 lock primitives tend to be limited in number and thus should not be wasted on
3157 a _DummyThread object. Fixes bug #1089632.
3158
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003159- The imghdr module now detects Exif files.
3160
Raymond Hettinger6065d322004-12-20 23:51:53 +00003161- StringIO.truncate() now correctly adjusts the size attribute.
3162 (Bug #951915).
3163
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003164- locale.py now uses an updated locale alias table (built using
3165 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3166 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003167 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003168
Raymond Hettinger3557f422004-12-07 12:02:02 +00003169- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3170
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003171- the pickle module no longer accepts the deprecated None option in the
3172 args tuple returned by __reduce__().
3173
Brett Cannon84667c02004-12-07 03:25:18 +00003174- optparse now optionally imports gettext. This allows its use in setup.py.
3175
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003176- the pickle module no longer uses the deprecated bin parameter.
3177
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003178- the shelve module no longer uses the deprecated binary parameter.
3179

3181
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003182- the filecmp module no longer uses the deprecated use_statcache argument.
3183
Raymond Hettinger664347b2004-12-04 21:21:53 +00003184- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3185 extended or overridden by subclasses. Formerly, the subclassed method would
3186 be ignored by the rest of the module. (Bug #1078905).
3187
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003188- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003189 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003190
Walter Dörwald36733692004-12-22 12:50:50 +00003191- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3192 once when a size argument is given. This prevents a buffer overflow in the
3193 tokenizer with very long source lines.
3194
Barry Warsaw538561e2006-01-01 21:48:54 +00003195- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3196 immediately after creating the object, without any intervening
3197 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003198
Skip Montanaro05885812005-01-16 20:48:27 +00003199- The reconvert.quote function can now emit triple-quoted strings. The
3200 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003201
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003202- ``UserString.MutableString`` now supports negative indices in
3203 ``__setitem__`` and ``__delitem__``
3204
Greg Ward40407942005-03-05 02:53:17 +00003205- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3206 correctly.
3207
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003208- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3209 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3210 character even if the user has passed a size parameter to get a proper
3211 line ending. Remove the special handling of a "\r\n" that has been split
3212 between two lines.
3213
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003214- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3215 about illegal code points. The codec now supports PEP 293 style error
3216 handlers.
3217
Walter Dörwald78a78b02005-09-01 12:04:29 +00003218- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003219 from the input stream, so that the output is a byte string in the correct
3220 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003221
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003222- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3223 considering it exactly like a '*'.
3224
Walter Dörwald007f8df2005-10-09 19:42:27 +00003225- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3226 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003227
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003228- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3229
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003230- Patch #1413711: Certain patterns of differences were making difflib
3231 touch the recursion limit.
3232
Walter Dörwald58917a62006-03-31 15:26:22 +00003233- Bug #947906: An object oriented interface has been added to the calendar
3234 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003235 called as a script (e.g. via ``python -mcalendar``). Localized month and
3236 weekday names can be ouput (even if an exotic encoding is used) using
3237 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003238
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003239Build
3240-----
3241
Neal Norwitz602d3392006-03-31 08:21:40 +00003242- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3243 by using -mieee gcc option.
3244
Martin v. Löwis86d66262006-02-17 08:40:11 +00003245- Patch #1432345: Make python compile on DragonFly.
3246
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003247- Build support for Win64-AMD64 was added.
3248
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003249- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3250
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003251- Patch #881820: look for openpty and forkpty also in libbsd.
3252
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003253- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3254 The zlib module is now builtin on Windows.
3255
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003256- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3257
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003258- Bug #1189330: configure did not correctly determine the necessary
3259 value of LINKCC if python was built with GCC 4.0.
3260
Trent Mick8321b422005-07-26 02:29:21 +00003261- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3262 vulnerability in zlib 1.2.1 and 1.2.2.
3263
Brett Cannon08cd5982005-04-24 22:26:38 +00003264- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3265 flags that change binary compatibility. Changes were also made to
3266 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003267 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003268
Bob Ippolitoed233462005-03-29 13:47:59 +00003269- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3270 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3271 no longer exists). This configure patch makes things right.
3272
Martin v. Löwise2713be2005-03-08 15:03:08 +00003273- Bug #1158607: Build with --disable-unicode again.
3274
Brett Cannon46d96232005-02-16 00:07:19 +00003275- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3276 defined. Discovered as a result of not being able to build on OS X.
3277
Brett Cannon516592f2004-12-07 00:42:59 +00003278- setup.py now uses the directories specified in LDFLAGS using the -L option
3279 and in CPPFLAGS using the -I option for adding library and include
3280 directories, respectively, for compiling extension modules against. This has
3281 led to the core being compiled using the values in CPPFLAGS. It also removes
3282 the need for the special-casing of both DarwinPorts and Fink for darwin since
3283 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3284 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3285 Fink, ``-I/opt/local/include`` for DarwinPorts).
3286
Brett Cannon43802422005-02-10 20:48:03 +00003287- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3288 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3289 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3290 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003292C API
3293-----
3294
Tim Petersc9d78aa2006-03-26 23:27:58 +00003295- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3296 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3297 is obtained via the ``PyObject_`` family, it must be released via the
3298 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3299 always been officially true, but when Python's small-object allocator was
3300 introduced, an attempt was made to cater to a few extension modules
3301 discovered at the time that obtained memory via ``PyObject_New`` but
3302 released it via ``PyMem_DEL``. It's years later, and if such code still
3303 exists it will fail now (probably with segfaults, but calling wrong
3304 low-level memory management functions can yield many symptoms).
3305
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003306- Added a C API for set and frozenset objects.
3307
Raymond Hettinger66517482004-12-03 11:45:13 +00003308- Removed PyRange_New().
3309
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003310- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3311 mapping argument now. This string is used as a mapping table. Byte values
3312 greater than the length of the string and 0xFFFE are treated as undefined
3313 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003320
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003321- Patch #1276356: New resource "urlfetch" is implemented. This enables
