11
12Core and builtins
13-----------------
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000014
Neal Norwitz4f3be8a2008-07-31 17:08:14 +000015- Apply security patches from Apple.
16
Neal Norwitz83ac0142008-07-28 05:06:20 +000017- Issue #2620: Overflow checking when allocating or reallocating memory
18 was not always being done properly in some python types and extension
19 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
20 all been updated to perform better checks and places in the code that
21 would previously leak memory on the error path when such an allocation
22 failed have been fixed.
23
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +000024- Issue #2242: Fix a crash when decoding invalid utf-7 input on certain
25 Windows / Visual Studio versions.
26
Mark Dickinsonab396e02008-07-16 11:04:17 +000027- Issue #3360: Fix incorrect parsing of '020000000000.0', which
28 produced a ValueError instead of giving the correct float.
29
Amaury Forgeot d'Arcceda6a62008-07-01 20:52:56 +000030- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
31 set to a custom object whose write() method happens to install
32 another file in sys.stdout.
33
Amaury Forgeot d'Arcb15bdf72008-07-01 20:59:49 +000034- Issue #3088: Corrected a race condition in classes derived from
35 threading.local: the first member set by a thread could be saved in
36 another thread's dictionary.
37
Amaury Forgeot d'Arc3255e132008-06-16 19:22:42 +000038- Issue #3100: Corrected a crash on deallocation of a subclassed weakref which
39 holds the last (strong) reference to its referent.
40
Guido van Rossumaa975432008-04-10 22:43:58 +000041- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
42 having a self-referential tuple, which is possible from C code. Nor did
43 object's tp_str consider that a type's tp_str could do something that could
44 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
45 respectively, fixed the issues. (Backport of r58288 from trunk.)
46
Georg Brandld9f1da02008-03-29 01:50:46 +000047- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
48 cannot be executed.
49
Amaury Forgeot d'Arc8432d862008-03-28 20:45:42 +000050- The compilation of a class nested in another class used to leak one
51 reference on the outer class name.
52
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000053- Issue #1477: With narrow Unicode builds, the unicode escape sequence
54 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
55 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
56 UTF-16 surrogates are generated in this case, like normal unicode literals
57 and the 'unicode-escape' codec.
58
Neal Norwitzb3635f92008-03-18 04:17:36 +000059- Issue #2321: use pymalloc for unicode object string data to reduce
60 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +000061
Sean Reifscheider4af861c2008-03-20 17:39:31 +000062- Issue #2238: Some syntax errors in *args and **kwargs expressions could give
63 bogus error messages.
64
Gregory P. Smith14acde32008-04-09 23:41:13 +000065- Issue #2587: In the C API, PyString_FromStringAndSize() takes a signed size
66 parameter but was not verifying that it was greater than zero. Values
67 less than zero will now raise a SystemError and return NULL to indicate a
68 bug in the calling C code.
69
Gregory P. Smith9aa040d2008-06-02 00:07:25 +000070- Issue #2588, #2589: Fix potential integer underflow and overflow
71 conditions in the PyOS_vsnprintf C API function.
72
Georg Brandld9f1da02008-03-29 01:50:46 +000073

78
Brett Cannonff931572008-07-13 01:20:19 +000079- Issue #3339: dummy_thread.acquire() could return None which is not a valid
80 return value.
81

88 handlers that derive the same default base class.
89
Amaury Forgeot d'Arc198e3532008-03-27 23:41:59 +000090- Issue #2495: tokenize.untokenize now inserts a space between two consecutive
91 string literals; previously, ["" ""] was rendered as [""""], which is
92 incorrect python code.
93
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +000094- Issue #2482: Make sure that the coefficient of a Decimal is always
95 stored as a str instance, not as a unicode instance. This ensures
96 that str(Decimal) is always an instance of str. This fixes a
97 regression from Python 2.5.1 to Python 2.5.2.
98
Mark Dickinson26c25d92008-03-25 14:35:25 +000099- Issue #2478: fix failure of decimal.Decimal(0).sqrt()

Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000116 calling .read() on a socket object wrapped with makefile().
Andrew M. Kuchling664553a2008-02-23 19:30:59 +0000117
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +0000118- Bug #1433694: minidom's .normalize() failed to set .nextSibling for
119 last child element.
120
Gregory P. Smith26660402008-06-01 23:44:46 +0000121- Issue #2791: subprocess.Popen.communicate explicitly closes its
122 stdout and stderr fds rather than leaving them open until the
123 instance is destroyed.
124
Gregory P. Smithf8f30fa2008-07-06 04:04:07 +0000125- Issue #2632: Prevent socket.read(bignumber) from over allocating memory
126 in the common case when the data is returned from the underlying socket
127 in increments much smaller than bignumber.
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +0000128
Gregory P. Smithb4bc9b92008-08-04 00:15:54 +0000129- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
130 argument in python 2.5, this broke code that subclassed Popen to include its
131 own poll method. Fixed my moving _deadstate to an _internal_poll method.

186-----------------
187
Martin v. Löwis73c01d42008-02-14 11:26:18 +0000188- Added checks for integer overflows, contributed by Google. Some are

Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000195- Issue #1920: "while 0" statements were completely removed by the compiler,
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000196 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000197 the condition is false. Now the compiler correctly emits bytecode for the
198 "else" suite.
199
Guido van Rossumd933e0a2008-01-24 18:28:37 +0000200- A few crashers fixed: weakref_in_del.py (issue #1377858);

Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001166 Instead, the equal (==) and unequal (!=) comparison operators will
1167 now issue a UnicodeWarning and interpret the two objects as
1168 unequal. The UnicodeWarning can be filtered as desired using
1169 the warning framework, e.g. silenced completely, turned into an
1170 exception, logged, etc.
1171
1172 Note that compare operators other than equal and unequal will still
1173 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001174
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001175- Fix segfault when doing string formatting on subclasses of long.
1176
1177- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1178 with new-style classes.
1179
1180- Fix bug related to __len__ functions returning negative values with
1181 classic classes.
1182
1183- Patch #1538606, Fix __index__() clipping. There were some problems
1184 discovered with the API and how integers that didn't fit into Py_ssize_t
1185 were handled. This patch attempts to provide enough alternatives
1186 to effectively use __index__.
1187
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001188- Bug #1536021: __hash__ may now return long int; the final hash
1189 value is obtained by invoking hash on the long int.
1190
Thomas Hellerab1049c2006-08-08 17:37:00 +00001191- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1192
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001193- Bug #1535165: fixed a segfault in input() and raw_input() when
1194 sys.stdin is closed.
1195
Thomas Heller74d36f02006-08-04 18:17:40 +00001196- On Windows, the PyErr_Warn function is now exported from
1197 the Python dll again.
1198
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001199- Bug #1191458: tracing over for loops now produces a line event
1200 on each iteration. Fixing this problem required changing the .pyc
1201 magic number. This means that .pyc files generated before 2.5c1
1202 will be regenerated.
1203
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001204- Bug #1333982: string/number constants were inappropriately stored
1205 in the byte code and co_consts even if they were not used, ie
1206 immediately popped off the stack.
1207
Georg Brandle9462c72006-08-04 18:03:37 +00001208- Fixed a reference-counting problem in property().

1211Library
1212-------
1213
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001214- Fix a bug in the ``compiler`` package that caused invalid code to be
1215 generated for generator expressions.
1216
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001217- The distutils version has been changed to 2.5.0. The change to
1218 keep it programmatically in sync with the Python version running
1219 the code (introduced in 2.5b3) has been reverted. It will continue
1220 to be maintained manually as static string literal.
1221
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001222- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001223 and this cannot be converted to the required C type, an exception is
1224 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001225 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001226
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001227- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001228 an exception.
1229
Tim Peterscbdd3502006-09-05 01:47:53 +00001230- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001231 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001232 workarounds for clocks with low resolution, to stop the code yielding
1233 duplicate UUIDs.
1234
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001235- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1236 before raising SystemExit, allowing IDLE to honor quit() and exit().
1237
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001238- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1239
Georg Brandl7a1af772006-08-14 21:55:28 +00001240- Patch #1536071: trace.py should now find the full module name of a
1241 file correctly even on Windows.
1242
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001243- logging's atexit hook now runs even if the rest of the module has
1244 already been cleaned up.
1245
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001246- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001247
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001248- Bug #1531405, format_exception no longer raises an exception if
1249 str(exception) raised an exception.
1250
Neil Schemenauer06ded092006-08-04 16:20:30 +00001251- Fix a bug in the ``compiler`` package that caused invalid code to be
1252 generated for nested functions.

1259
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001260- Patch #1511317: don't crash on invalid hostname (alias) info.
1261
Georg Brandl3335a7a2006-08-14 21:42:55 +00001262- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1263 raises the correct exceptions.
1264
Thomas Heller1ce433e2006-08-14 16:20:04 +00001265- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1266 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1267
Thomas Heller86720042006-08-14 11:17:48 +00001268- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1269 uses the _as_parameter_ attribute when objects are passed to foreign
1270 function calls. The ctypes version number was changed to 1.0.1.
1271
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001272- Bug #1530559, struct.pack raises TypeError where it used to convert.
1273 Passing float arguments to struct.pack when integers are expected
1274 now triggers a DeprecationWarning.
1275
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001276
1277Tests

1279
Neal Norwitzb476fdf2006-08-15 04:58:28 +00001280- test_socketserver should now work on cygwin and not fail sporadically
1281 on other platforms.
1282
Neal Norwitz003c9e22006-08-11 06:09:41 +00001283- test_mailbox should now work on cygwin versions 2006-08-10 and later.

1286
Andrew MacIntyre16ee33a2006-08-06 12:37:03 +00001287- test_threading now skips testing alternate thread stack sizes on
1288 platforms that don't support changing thread stack size.

1298-----
1299
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001300- Bug #1535502, build _hashlib on Windows, and use masm assembler
1301 code in OpenSSL.
1302
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001303- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.
1304
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001305- Bug #1530448, ctypes build failure on Solaris 10 was fixed.
Thomas Heller17984892006-08-04 18:57:34 +00001306

Tim Peters4643c2f2006-08-10 22:45:34 +00001308C API
1309-----
1310
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001311- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1312
Tim Peters4643c2f2006-08-10 22:45:34 +00001313- Bug #1069160. Internal correctness changes were made to
1314 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1315 the documentation was changed to state that the return value
1316 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001319What's New in Python 2.5 beta 3?
1320================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001321
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001322*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001323
1324Core and builtins
1325-----------------
1326
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001327- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001328 returned a long (see PEP 353).
1329
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001330- Bug #1515471: string.replace() accepts character buffers again.
1331
Neal Norwitz07aadb12006-07-30 06:55:48 +00001332- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1333 This provides the proper warning for struct.pack().
1334 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1335
Neal Norwitz0d62a062006-07-30 06:53:31 +00001336- Patch #1531113: Fix augmented assignment with yield expressions.
1337 Also fix a SystemError when trying to assign to yield expressions.
1338
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001339- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1340 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1341 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1342 excessive filesystem operations during imports.
1343
Tim Petersbc24eee2006-07-27 01:14:53 +00001344- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1345 operations on signed longs that are formally undefined by C.
1346 Unfortunately, at least one compiler now cares about that, so complicated
1347 the code to make that compiler happy again.
1348
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001349- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1350
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001351- Patch #1232023: Stop including current directory in search
1352 path on Windows.
1353
Neal Norwitze1fdb322006-07-21 05:32:28 +00001354- Fix some potential crashes found with failmalloc.
1355
Neal Norwitze7563102006-07-17 01:00:16 +00001356- Fix warnings reported by Klocwork's static analysis tool.
1357
Neal Norwitz84be93b2006-07-16 01:50:38 +00001358- Bug #1512814, Fix incorrect lineno's when code within a function
1359 had more than 255 blank lines.
1360
Georg Brandl9dceedb2006-07-12 15:31:17 +00001361- Patch #1521179: Python now accepts the standard options ``--help`` and
1362 ``--version`` as well as ``/?`` on Windows.
1363
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001364- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001365 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001366 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001367
Tim Peters112aad32006-07-19 00:03:19 +00001368- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001369 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001370 new ``sys._current_frames()`` returns a dictionary with one entry,
1371 mapping the faux "thread id" 0 to the current frame.
1372
Ronald Oussoren3075e162006-07-25 20:28:55 +00001373- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001374
Ronald Oussoren3075e162006-07-25 20:28:55 +00001375
Neal Norwitza1f10902006-07-12 07:28:29 +00001376Library
1377-------
1378
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001379- Correction of patch #1455898: In the mbcs decoder, set final=False
1380 for stream decoder, but final=True for the decode function.
1381
Georg Brandl07fec3a2006-08-01 18:49:24 +00001382- os.urandom no longer masks unrelated exceptions like SystemExit or
1383 KeyboardInterrupt.
1384
Tim Peters4643c2f2006-08-10 22:45:34 +00001385- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001386 shutil.copytree on Windows
1387
Georg Brandle34ac7c2006-07-30 11:07:23 +00001388- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1389 refers to file descriptors, not file objects.
1390
Tim Peterscbdd3502006-09-05 01:47:53 +00001391- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001392 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001393 #1513611, and probably others.
1394
Georg Brandledd9b0d2006-07-29 09:33:26 +00001395- Bug #1441397: The compiler module now recognizes module and function
1396 docstrings correctly as it did in Python 2.4.
1397
Tim Peters6f681472006-07-27 23:44:37 +00001398- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1399 lost that tests are sorted by name before being run. This rarely
1400 matters for well-written tests, but can create baffling symptoms if
1401 side effects from one test to the next affect outcomes. ``DocTestFinder``
1402 has been changed to sort the list of tests it returns.
1403
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001404- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001405 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001406
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001407- Bug #978833: Really close underlying socket in _socketobject.close.
1408
Georg Brandldb232dc2006-08-20 13:15:43 +00001409- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1410 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001411
Georg Brandlcf0c1722006-07-26 07:23:32 +00001412- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1413 to recursive calls and call it with the failing package name.
1414
Martin v. Löwis0b483032006-07-25 09:53:12 +00001415- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1416
Georg Brandlc13c34c2006-07-24 14:09:56 +00001417- Patch #1515343: Fix printing of deprecated string exceptions with a
1418 value in the traceback module.
1419
Greg Ward48fae7a2006-07-23 16:05:51 +00001420- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1421
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001422- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1423
Brett Cannoncaebe222006-07-18 04:41:36 +00001424- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1425 argument tuple. For arguments where zero is illegal, the value is forced to
1426 the minimum value that is correct. This is to support an undocumented but
1427 common way people used to fill in inconsequential information in the time
1428 tuple pre-2.4.
1429
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001430- Patch #1220874: Update the binhex module for Mach-O.
1431
Barry Warsawb110bad2006-07-21 14:51:07 +00001432- The email package has improved RFC 2231 support, specifically for
1433 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1434 (name*0=<blah>) parameter continuations. This may change the types of
1435 values returned from email.message.Message.get_param() and friends.
1436 Specifically in some cases where non-encoded continuations were used,
1437 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1438 will just return the string (since non-encoded continuations don't have
1439 charset and language parts).
1440
1441 Also, whereas % values were decoded in all parameter continuations, they are
1442 now only decoded in encoded parameter parts.
1443
Ronald Oussoren3075e162006-07-25 20:28:55 +00001444- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1445
1446- Bug #1517996: IDLE now longer shows the default Tk menu when a
1447 path browser, class browser or debugger is the frontmost window on MacOS X

Barry Warsaw00decd72006-07-27 23:43:15 +00001449- Patch #1520294: Support for getset and member descriptors in types.py,
1450 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1451 of an object against these built-in types and more importantly, for getting
1452 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001455Extension Modules
1456-----------------
1457
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001458- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1459 a socket operation on a socket with a timeout, the exception will be
1460 caught correctly. Previously, the exception was not caught.
1461
Thomas Heller1393d6a2006-07-28 21:43:20 +00001462- Patch #1529514: The _ctypes extension is now compiled on more
1463 openbsd target platforms.
1464
Tim Peters9cab5932006-07-28 00:30:00 +00001465- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1466 a memory leak, affecting pickles and deep copies.
1467
Tim Petersbc24eee2006-07-27 01:14:53 +00001468- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1472
Thomas Hellerce049a02006-07-14 17:51:14 +00001473- Patch #1521817: Index range checking on ctypes arrays containing
1474 exactly one element enabled again. This allows iterating over these
1475 arrays, without the need to check the array size before.
1476
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001477- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001478 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001479 /dev/null in certain cases; this is now fixed.
1480
Thomas Heller47d7a062006-07-12 08:43:47 +00001481- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1482 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001483
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001484- Because of a misspelled preprocessor symbol, ctypes was always
1485 compiled without thread support; this is now fixed.
1486
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001487- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1488 methods now allow their database parameter to be None as the
1489 sleepycat API allows.
1490
Matt Flemingec926502006-07-28 11:27:27 +00001491- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1492 bluetooth API compared with Linux and FreeBSD.
1493
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001494Tests
1495-----
1496
1497- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1498 how long the test file should take to play. Now accepts taking 2.93 secs
1499 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1500
Georg Brandl4793aa32006-07-28 18:31:39 +00001501- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1502 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1503 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +00001504
Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001505Build
1506-----
1507
1508- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1509
Ronald Oussoren26cad082006-08-01 21:00:57 +00001510Mac
1511---
1512
1513- PythonLauncher now works correctly when the path to the script contains
1514 characters that are treated specially by the shell (such as quotes).
1515
1516- Bug #1527397: PythonLauncher now launches scripts with the working directory
1517 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001518 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001519 expect.

1527Core and builtins
1528-----------------
1529
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001530- Bug #1441486: The literal representation of -(sys.maxint - 1)
1531 again evaluates to a int object, not a long.
1532
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001533- Bug #1501934: The scope of global variables that are locally assigned
1534 using augmented assignment is now correctly determined.
1535
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001536- Bug #927248: Recursive method-wrapper objects can now safely
1537 be released.
1538
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001539- Bug #1417699: Reject locale-specific decimal point in float()
1540 and atof().
1541
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001542- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1543 omit a default "error" argument for NULL pointer. This allows
1544 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001545
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001546- Bug #1519018: 'as' is now validated properly in import statements.
1547
Neal Norwitz28746ab2006-07-09 22:14:42 +00001548- On 64 bit systems, int literals that use less than 64 bits are
1549 now ints rather than longs.
1550
Neal Norwitzed657552006-07-10 00:04:44 +00001551- Bug #1512814, Fix incorrect lineno's when code at module scope
1552 started after line 256.
1553
Tim Peters32a83612006-07-10 21:08:24 +00001554- New function ``sys._current_frames()`` returns a dict mapping thread
1555 id to topmost thread stack frame. This is for expert use, and is
1556 especially useful for debugging application deadlocks. The functionality
1557 was previously available in Fazal Majid's ``threadframe`` extension
1558 module, but it wasn't possible to do this in a wholly threadsafe way from
1559 an extension.
1560

1568
Tim Peters32a83612006-07-10 21:08:24 +00001569- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001570 environment variable to be set in order to the SDK environment
1571 for finding the compiler, include files, etc.

1576
Thomas Woutersadd19112006-07-05 11:03:49 +00001577- string.Template() now correctly handles tuple-values. Previously,
1578 multi-value tuples would raise an exception and single-value tuples would
1579 be treated as the value they contain, instead.
1580
Martin v. Löwisede77f52006-07-03 13:01:35 +00001581- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1582 even if some data are received.
1583
Martin v. Löwis45482392006-07-03 12:28:58 +00001584- Bug #1267547: Put proper recursive setup.py call into the

1588 degrees and radians.
1589
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001590- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001591 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001592
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001593- Bug #1514703: Only setup canvas window in turtle when the canvas
1594 is created.
1595
Martin v. Löwis7596e832006-07-01 15:33:37 +00001596- Bug #1513223: .close() of a _socketobj now releases the underlying

1600 attribute values.
1601
1602- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1603 sgmllib ('[' and ']' were not accepted).
1604
Georg Brandl1be63af2006-06-28 20:23:25 +00001605- Fix a bug in the turtle module's end_fill function.
1606
Brett Cannon53ab5b72006-06-22 16:49:14 +00001607- Bug #1510580: The 'warnings' module improperly required that a Warning
1608 category be either a types.ClassType and a subclass of Warning. The proper
1609 check is just that it is a subclass with Warning as the documentation states.
1610
Georg Brandlad29e632006-06-21 17:45:17 +00001611- The compiler module now correctly compiles the new try-except-finally
1612 statement (bug #1509132).
1613
Neal Norwitz60373cd2006-06-22 06:30:50 +00001614- The wsgiref package is now installed properly on Unix.
1615
Vinay Sajip28e57612006-07-01 10:45:20 +00001616- A bug was fixed in logging.config.fileConfig() which caused a crash on
1617 shutdown when fileConfig() was called multiple times.
1618
Gerhard Häring762fbd32006-07-02 17:48:30 +00001619- The sqlite3 module did cut off data from the SQLite database at the first
1620 null character before sending it to a custom converter. This has been fixed
1621 now.
1622
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001623Extension Modules
1624-----------------
1625
Tim Peters112aad32006-07-19 00:03:19 +00001626- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1627 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1628 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001629
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001630- Assigning None to pointer type fields in ctypes structures possible
1631 overwrote the wrong fields, this is fixed now.
1632
1633- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1634 on non-Windows platforms.
1635
1636- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1637 integer or long, without range checking.
1638
1639- Patch #1517790: It is now possible to use custom objects in the ctypes
1640 foreign function argtypes sequence as long as they provide a from_param
1641 method, no longer is it required that the object is a ctypes type.
1642
1643- The '_ctypes' extension module now works when Python is configured
1644 with the --without-threads option.
1645
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001646- Bug #1513646: os.access on Windows now correctly determines write
1647 access, again.
1648
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001649- Bug #1512695: cPickle.loads could crash if it was interrupted with
1650 a KeyboardInterrupt.
1651
Neal Norwitza12aa882006-07-06 06:45:08 +00001652- Bug #1296433: parsing XML with a non-default encoding and
1653 a CharacterDataHandler could crash the interpreter in pyexpat.
1654
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001655- Patch #1516912: improve Modules support for OpenVMS.

1661
Tim Peters32a83612006-07-10 21:08:24 +00001662- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001663 Previously, the slight difference could cause compilation errors of the
1664 'zlib' module on systems with more than one version of zlib.
1665
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001666- The MSI compileall step was fixed to also support a TARGETDIR
1667 with spaces in it.
1668
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001669- Bug #1517388: sqlite3.dll is now installed on Windows independent

1682-------------
1683
Nick Coghlan2d792252006-07-06 13:47:18 +00001684- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1685 documentation for the warnings module.
1686
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001687- Patch #1509163: MS Toolkit Compiler no longer available.

1698-----------------
1699
Georg Brandla56b9152006-06-19 06:35:54 +00001700- Patch #1507676: Error messages returned by invalid abstract object operations
1701 (such as iterating over an integer) have been improved and now include the
1702 type of the offending object to help with debugging.
1703
Brett Cannonea3912b2006-06-13 21:46:41 +00001704- Bug #992017: A classic class that defined a __coerce__() method that returned
1705 its arguments swapped would infinitely recurse and segfault the interpreter.
1706
Neal Norwitz909eb122006-06-12 02:13:21 +00001707- Fix the socket tests so they can be run concurrently.
1708
Neal Norwitzb9845e72006-06-12 02:11:18 +00001709- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001710 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001711
Brett Cannon22565aa2006-06-09 22:31:23 +00001712- Bug #532646: object.__call__() will continue looking for the __call__
1713 attribute on objects until one without one is found. This leads to recursion
1714 when you take a class and set its __call__ attribute to an instance of the
1715 class. Originally fixed for classic classes, but this fix is for new-style.
1716 Removes the infinite_rec_3 crasher.
1717
Georg Brandl24250812006-06-09 18:45:48 +00001718- The string and unicode methods startswith() and endswith() now accept
1719 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1720
Brett Cannonde3b0522006-06-08 17:00:45 +00001721- Buffer objects, at the C level, never used the char buffer
1722 implementation even when the char buffer for the wrapped object was
1723 explicitly requested (originally returned the read or write buffer).
1724 Now a TypeError is raised if the char buffer is not present but is
1725 requested.
1726
Georg Brandlddbaa662006-06-04 21:56:52 +00001727- Patch #1346214: Statements like "if 0: suite" are now again optimized
1728 away like they were in Python 2.4.
1729
Georg Brandlb7c8f542006-05-27 12:30:25 +00001730- Builtin exceptions are now full-blown new-style classes instead of
1731 instances pretending to be classes, which speeds up exception handling
1732 by about 80% in comparison to 2.5a2.
1733
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001734- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1735 Unicode 4.1.
1736
Georg Brandlf4ef1162006-05-26 18:03:31 +00001737- Patch #921466: sys.path_importer_cache is now used to cache valid and
1738 invalid file paths for the built-in import machinery which leads to
1739 fewer open calls on startup.
1740
Tim Peters696cf432006-05-24 21:10:40 +00001741- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1742 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1743 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1744 the number of input digits (it was and remains linear-time for bases
1745 2, 4, 8, 16 and 32).
1746
Tim Petersb713ec22006-05-23 18:45:30 +00001747- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1748 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1749 an integer close to ``sys.maxint``. This was repaired by patch
1750 #1335972, which also gives a nice speedup.
1751
Richard Jonescebbefc2006-05-23 18:28:17 +00001752- Patch #1337051: reduced size of frame objects.
1753
1754- PyErr_NewException now accepts a tuple of base classes as its
1755 "base" parameter.
1756
Richard Jones7c88dcc2006-05-23 10:37:38 +00001757- Patch #876206: function call speedup by retaining allocated frame
1758 objects.
1759
Georg Brandl7b90e162006-05-18 07:01:27 +00001760- Bug #1462152: file() now checks more thoroughly for invalid mode
1761 strings and removes a possible "U" before passing the mode to the
1762 C library function.
1763
Neal Norwitz1004a532006-05-15 07:17:23 +00001764- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1765
Neal Norwitz373f0a72006-05-15 07:04:36 +00001766- Bug #1487966: Fix SystemError with conditional expression in assignment
1767
Martin v. Löwis879768d2006-05-11 13:28:43 +00001768- WindowsError now has two error code attributes: errno, which carries
1769 the error values from errno.h, and winerror, which carries the error
1770 values from winerror.h. Previous versions put the winerror.h values
1771 (from GetLastError()) into the errno attribute.
1772
Martin v. Löwis77736712006-05-04 05:51:03 +00001773- Patch #1475845: Raise IndentationError for unexpected indent.
1774
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001775- Patch #1479181: split open() and file() from being aliases for each other.
1776
Tim Peters44bd9862006-06-01 13:49:23 +00001777- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1778 methods were always silently ignored by dictionaries when comparing keys.
1779 They are now passed through (except when using the C API function
1780 ``PyDict_GetItem()``, whose semantics did not change).
1781
1782- Bug #1456209: In some obscure cases it was possible for a class with a
1783 custom ``__eq__()`` method to confuse dict internals when class instances
1784 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1785 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001787Extension Modules
1788-----------------
1789
Trent Mick960a3f82006-06-28 20:30:41 +00001790- Bug #1295808: expat symbols should be namespaced in pyexpat
1791
1792- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1793
Brett Cannon6ee7d012006-06-08 16:23:04 +00001794- Change binascii.hexlify to accept a read-only buffer instead of only a char
1795 buffer and actually follow its documentation.
1796
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001797- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1798
Nick Coghlanc649ec52006-05-29 12:43:05 +00001799- Patch #1478788 (modified version): The functional extension module has
1800 been renamed to _functools and a functools Python wrapper module added.
1801 This provides a home for additional function related utilities that are
1802 not specifically about functional programming. See PEP 309.
1803
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001804- Patch #1493701: performance enhancements for struct module.
1805
Georg Brandl378d5922006-05-17 14:26:50 +00001806- Patch #1490224: time.altzone is now set correctly on Cygwin.
1807
Georg Brandl8d3342b2006-05-16 07:38:27 +00001808- Patch #1435422: zlib's compress and decompress objects now have a
1809 copy() method.
1810
Andrew MacIntyre92913322006-06-13 15:04:24 +00001811- Patch #1454481: thread stack size is now tunable at runtime for thread
1812 enabled builds on Windows and systems with Posix threads support.
1813
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001814- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1815 (up to the system limit of 32K characters).
1816
1817- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1818 As a result, these functions now raise WindowsError instead of OSError.
1819
Tim Peters7a822da2006-05-25 21:50:17 +00001820- ``time.clock()`` on Win64 should use the high-performance Windows
1821 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1822 Windows platforms).
1823
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001824- Calling Tk_Init twice is refused if the first call failed as that
1825 may deadlock.
1826
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001827- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1828 accept it without potentially using an uninitialized pointer.
1829
1830- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1831 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1832 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001833
Gregory P. Smith372b5832006-06-05 18:48:21 +00001834- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001835 [pybsddb project SF patch number 1466734]
1836
Gregory P. Smith372b5832006-06-05 18:48:21 +00001837- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1838 parameter is supplied. [SF pybsddb bug #1477863]
1839
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001840- bsddb: the __len__ method of a DB object has been fixed to return correct
1841 results. It could previously incorrectly return 0 in some cases.
1842 Fixes SF bug 1493322 (pybsddb bug 1184012).
1843
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001844- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1845 aborts the db transaction safely when a modifier callback fails.
1846 Fixes SF python patch/bug #1408584.
1847
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001848- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001849 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001850 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1851 database calls that would previously deadlock. [SF python bug #775414]
1852
Vinay Sajip28e57612006-07-01 10:45:20 +00001853- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001854
Walter Dörwald4994d952006-06-19 08:07:50 +00001855- Patch #1506645: add Python wrappers for the curses functions
1856 is_term_resized, resize_term and resizeterm.

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001861- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1862 functions.
1863
Martin v. Löwis3798da02006-06-17 18:44:27 +00001864- Patch #812986: Update turtle output even if not tracing.

Vinay Sajip28e57612006-07-01 10:45:20 +00001866- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001867 Tkinter.BaseWidget.
1868
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001869- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1870
Martin v. Löwis337487e2006-06-17 09:15:14 +00001871- Patch #763580: Add name and value arguments to Tkinter variable
1872 classes.
1873
Georg Brandl83cc0d02006-06-14 08:50:03 +00001874- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1875 mime.types file for determining MIME types.
1876
Georg Brandl2605ca82006-06-14 06:08:31 +00001877- Bug #1339007: Shelf objects now don't raise an exception in their
1878 __del__ method when initialization failed.
1879
Martin v. Löwisd8251432006-06-14 05:21:04 +00001880- Patch #1455898: The MBCS codec now supports the incremental mode for
1881 double-byte encodings.
1882
Tim Peters43898b42006-06-14 04:09:25 +00001883- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1884 guarantee that adjacent triples in the return list always describe
1885 non-adjacent blocks. Previously, a pair of matching blocks could end
1886 up being described by multiple adjacent triples that formed a partition
1887 of the matching pair.
1888
Greg Ward0e0c9f42006-06-11 16:24:11 +00001889- Bug #1498146: fix optparse to handle Unicode strings in option help,
1890 description, and epilog.
1891
Greg Wardd1c797e2006-06-11 14:42:41 +00001892- Bug #1366250: minor optparse documentation error.
1893
Greg Ward7f547402006-06-11 00:40:49 +00001894- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1895 clarify docs.
1896
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001897- The wsgiref package has been added to the standard library.
1898
Nick Coghlan676725d2006-06-08 13:54:49 +00001899- The functions update_wrapper() and wraps() have been added to the functools
1900 module. These make it easier to copy relevant metadata from the original
1901 function when writing wrapper functions.
1902
Tim Petersd6a9eef2006-06-05 01:48:21 +00001903- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1904 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001905
Martin v. Löwis3f767792006-06-04 19:36:28 +00001906- Patch #1359618: Speed up charmap encoder by using a trie structure
1907 for lookup.
1908
Tim Petersd609b1a2006-06-02 23:22:51 +00001909- The functions in the ``pprint`` module now sort dictionaries by key
1910 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1911 if and only if its display required more than one line, although that
1912 wasn't documented. The new behavior increases predictability; e.g.,
1913 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1914
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001915- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1916 (thanks for J. J. Lee).
1917
Georg Brandl2b330372006-05-28 20:23:12 +00001918- Patch #1496206: improve urllib2 handling of passwords with respect to
1919 default HTTP and HTTPS ports.
1920
George Yoshidaf3c65de2006-05-28 16:39:09 +00001921- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1922
Bob Ippolito7298f272006-05-23 18:43:47 +00001923- Patch #1281707: speed up gzip.readline.
1924
Georg Brandlb89316f2006-05-17 15:51:16 +00001925- Patch #1180296: Two new functions were added to the locale module:
1926 format_string() to get the effect of "format % items" but locale-aware,
1927 and currency() to format a monetary number with currency sign.
1928
Georg Brandle3a25832006-05-17 14:56:04 +00001929- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1930 and several features added, such as speed and geometry control.
1931
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001932- Patch #1488881: add support for external file objects in bz2 compressed
1933 tarfiles.
1934
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001935- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1936 stdout arguments, making it possible to redirect input and output
1937 for remote debugging.
1938
1939- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1940 a couple of issues, notably handling of long file names using the
1941 GNU LONGNAME extension.
1942
1943- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1944 new flag when ``name`` is already the name of an option flag.
1945
1946- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1947 package.
1948
1949- Patch #1472854: make the rlcompleter.Completer class usable on non-
1950 UNIX platforms.
1951
1952- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1953
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001954- Bug #1472827: correctly escape newlines and tabs in attribute values in
1955 the saxutils.XMLGenerator class.

1991-----------------
1992
Thomas Heller1b046642006-04-18 18:51:06 +00001993- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1994 by converting these apis from macros into exported functions again:
1995
1996 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1997 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1998 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

2000 PyRun_String Py_CompileString
2001
Martin v. Löwis45294a92006-04-18 06:24:08 +00002002- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2003
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002004- All uses of PyStructSequence_InitType have been changed to initialize
2005 the type objects only once, even if the interpreter is initialized
2006 multiple times.
2007
Neal Norwitz61546162006-04-14 05:20:28 +00002008- Bug #1454485, array.array('u') could crash the interpreter. This was
2009 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2010 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2011
2012- Py_UNICODE is unsigned. It was always documented as unsigned, but
2013 due to a bug had a signed value in previous versions.
2014
Tim Peters3a5e8b12006-04-11 01:44:07 +00002015- Patch #837242: ``id()`` of any Python object always gives a positive
2016 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2017 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002018 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002019 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002020
Tim Peters3a5e8b12006-04-11 01:44:07 +00002021 def __hash__(self):
2022 return id(self) # WRONG
2023
2024 because a hash result must be a (short) Python int but it was always
2025 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002026 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002027 was always usable as a hash value before this patch. That's no longer
2028 necessarily so.
2029
2030- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002031 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002032 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002033 #1454844)
2034
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002035- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2036 involving generators that have paused outside of any ``try`` or ``with``
2037 blocks. (In 2.5a1, a paused generator that was part of a reference
2038 cycle could not be garbage collected, regardless of whether it was
2039 paused in a ``try`` or ``with`` block.)

Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00002044- Patch #1191065: Fix preprocessor problems on systems where recvfrom
2045 is a macro.

Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002047- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2048 fails with an error condition.
2049
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002050- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2051
2052- Bug #1117761: bsddb.*open() no longer raises an exception when using
2053 the cachesize parameter.
2054
2055- Bug #1149413: bsddb.*open() no longer raises an exception when using
2056 a temporary db (file=None) with the 'n' flag to truncate on open.
2057
2058- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2059 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002060
Armin Rigoa9017c32006-04-19 11:50:27 +00002061- Patch #1062014: AF_UNIX sockets under Linux have a special
2062 abstract namespace that is now fully supported.

Peter Astrand7d1d4362006-07-14 14:04:45 +00002067- Bug #1223937: subprocess.CalledProcessError reports the exit status
2068 of the process using the returncode attribute, instead of
2069 abusing errno.
2070
Tim Peters711bf302006-04-25 03:31:36 +00002071- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2072 a doctest to be skipped (the code is not run, and the expected output
2073 or exception is ignored).
2074
Nick Coghlanda2268f2006-04-24 04:37:15 +00002075- Fixed contextlib.nested to cope with exceptions being raised and
2076 caught inside exit handlers.
2077
Greg Wardab05edc2006-04-23 03:47:58 +00002078- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2079 hex, octal, or binary; add ``append_const`` action; keep going if
2080 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2081 added ``epilog`` for better help generation).
2082
Tim Peters21fbd572006-04-21 21:18:10 +00002083- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2084 called from a thread spawned as a side effect of importing a module.
2085
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002086- The pydoc module now supports documenting packages contained in
2087 .zip or .egg files.
2088
2089- The pkgutil module now has several new utility functions, such
2090 as ``walk_packages()`` to support working with packages that are either
2091 in the filesystem or zip files.
2092
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002093- The mailbox module can now modify and delete messages from
2094 mailboxes, in addition to simply reading them. Thanks to Gregory
2095 K. Johnson for writing the code, and to the 2005 Google Summer of
2096 Code for funding his work.

Skip Montanaro262fb922006-04-21 02:31:07 +00002121- The pstats.Stats class accepts an optional stream keyword argument to
2122 direct output to an alternate file-like object.
2123

2125-----
2126
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002127- The Makefile now has a reindent target, which runs reindent.py on
2128 the library.
2129
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002130- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis0f48d982006-04-14 14:34:26 +00002134- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2135 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002136 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002137 CXX from --with-cxx-main, see description in README.
2138
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002139- Patch #1429775: Link extension modules with the shared libpython.

2148-----
2149
Nick Coghlanda2268f2006-04-24 04:37:15 +00002150- test_contextlib now checks contextlib.nested can cope with exceptions
2151 being raised and caught inside exit handlers.
2152
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002153- test_cmd_line now checks operation of the -m and -c command switches
2154
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002155- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2156 it separately and by hand. It also wasn't cleaning up its changes to
2157 the current Decimal context.
2158
Thomas Woutersabd08882006-04-26 15:53:30 +00002159- regrtest.py now has a -M option to run tests that test the new limits of
2160 containers, on 64-bit architectures. Running these tests is only sensible
2161 on 64-bit machines with more than two gigabytes of memory. The argument
2162 passed is the maximum amount of memory for the tests to use.

2171-------------
2172
Tim Petersb06d28c2006-05-12 01:57:59 +00002173- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2174
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002175- PEP 343: Added Context Types section to the library reference
2176 and attempted to bring other PEP 343 related documentation into
2177 line with the implementation and/or python-dev discussions.
2178
Tim Peters8dc73d22006-04-24 02:03:16 +00002179- Bug #1337990: clarified that ``doctest`` does not support examples
2180 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002183What's New in Python 2.5 alpha 1?
2184=================================
2185
Anthony Baxterebed3f62006-04-03 15:03:44 +00002186*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002187
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002188Core and builtins
2189-----------------
2190
Nick Coghlan43832302006-04-23 17:04:07 +00002191- PEP 338: -m command line switch now delegates to runpy.run_module
2192 allowing it to support modules in packages and zipfiles
2193
Martin v. Löwisc661b882006-04-20 04:54:23 +00002194- On Windows, .DLL is not an accepted file name extension for
2195 extension modules anymore; extensions are only found if they
2196 end in .PYD.
2197
Martin v. Löwisea62d252006-04-03 10:56:49 +00002198- Bug #1421664: sys.stderr.encoding is now set to the same value as
2199 sys.stdout.encoding.
2200
Neal Norwitz92e212f2006-04-03 04:48:37 +00002201- __import__ accepts keyword arguments.
2202
Georg Brandlccadf842006-03-31 18:54:53 +00002203- Patch #1460496: round() now accepts keyword arguments.
2204
Anthony Baxter262c00a2006-03-30 10:53:17 +00002205- Fixed bug #1459029 - unicode reprs were double-escaped.
2206
Hye-Shik Changd478f342006-03-23 12:32:36 +00002207- Patch #1396919: The system scope threads are reenabled on FreeBSD
2208 5.4 and later versions.
2209
Neal Norwitze98ccf62006-03-23 05:39:47 +00002210- Bug #1115379: Compiling a Unicode string with an encoding declaration
2211 now gives a SyntaxError.
2212
Georg Brandlabd1ff82006-03-18 07:59:59 +00002213- Previously, Python code had no easy way to access the contents of a
2214 cell object. Now, a ``cell_contents`` attribute has been added
2215 (closes patch #1170323).
2216
Tim Peterscf79aac2006-03-16 01:14:46 +00002217- Patch #1123430: Python's small-object allocator now returns an arena to
2218 the system ``free()`` when all memory within an arena becomes unused
2219 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2220 freed. Some applications will see a drop in virtual memory size now,
2221 especially long-running applications that, from time to time, temporarily
2222 use a large number of small objects. Note that when Python returns an
2223 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002224 platform C library will in turn return that memory to the operating system.
2225 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002226 appears to be effective at least on Microsoft C and gcc-based systems.
2227 Thanks to Evan Jones for hard work and patience.
2228
Georg Brandl533ff6f2006-03-08 18:09:27 +00002229- Patch #1434038: property() now uses the getter's docstring if there is
2230 no "doc" argument given. This makes it possible to legitimately use
2231 property() as a decorator to produce a read-only property.
2232
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002233- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2234 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2235 of requiring an int or long in slicing and a few other contexts, enabling
2236 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2237
Neal Norwitz995acdf2006-03-07 05:01:00 +00002238- Fixed various bugs reported by Coverity's Prevent tool.
2239
Brett Cannonbf364092006-03-01 04:25:17 +00002240- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2241 new exception base class, BaseException, which has a new message attribute.
2242 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2243 Raising a string exception now raises a DeprecationWarning.
2244
Thomas Woutersfb609f42006-02-28 16:37:25 +00002245- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2246 explicitly relative, using 'from .module import name' to mean 'from the same
2247 package as this module is in. Imports without dots still default to the
2248 old relative-then-absolute, unless 'from __future__ import
2249 absolute_import' is used.
2250
Brett Cannona7446e32006-02-27 23:39:10 +00002251- Properly check if 'warnings' raises an exception (usually when a filter set
2252 to "error" is triggered) when raising a warning for raising string
2253 exceptions.
2254
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002255- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002256 The name was removed from Include/code.h.
2257
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002258- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002259
Guido van Rossum1968ad32006-02-25 22:38:04 +00002260- Patch 1433928:
2261 - The copy module now "copies" function objects (as atomic objects).
2262 - dict.__getitem__ now looks for a __missing__ hook before raising
2263 KeyError.
2264
Tim Peters84ef21c2006-02-28 20:39:06 +00002265- PEP 343: with statement implemented. Needs ``from __future__ import
2266 with_statement``. Use of 'with' as a variable will generate a warning.
2267 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002268 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002269 The following objects have __context__ methods:
2270 - The built-in file type.
2271 - The thread.LockType type.
2272 - The following types defined by the threading module:
2273 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2274 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002275
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002276- Fix the encodings package codec search function to only search
2277 inside its own package. Fixes problem reported in patch #1433198.
2278
2279 Note: Codec packages should implement and register their own
2280 codec search function. PEP 100 has the details.
2281
Tim Peters9ea89d22006-06-04 03:26:02 +00002282- PEP 353: Using ``Py_ssize_t`` as the index type.
2283
2284- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2285 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2286 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2287 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2288 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002289
Neal Norwitzfc76d632006-01-10 06:03:13 +00002290- Patch #1400181, fix unicode string formatting to not use the locale.
2291 This is how string objects work. u'%f' could use , instead of .
2292 for the decimal point. Now both strings and unicode always use periods.
2293
Neal Norwitz671b9e32006-01-09 07:07:12 +00002294- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2295 configure would break checking curses.h.
2296
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002297- Bug #959576: The pwd module is now builtin. This allows Python to be
2298 built on UNIX platforms without $HOME set.
2299
Neal Norwitzc10978f2005-12-19 06:07:16 +00002300- Bug #1072182, fix some potential problems if characters are signed.
2301
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002302- Bug #889500, fix line number on SyntaxWarning for global declarations.
2303
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002304- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2305
Neal Norwitze7214a12005-12-18 05:03:17 +00002306- Support for converting hex strings to floats no longer works.
2307 This was not portable. float('0x3') now raises a ValueError.
2308
Barry Warsaw2a38a862005-12-18 01:27:35 +00002309- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002310 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002311 is now displayed in interactive prompt banner.
2312
Georg Brandlfa166682005-12-17 21:45:17 +00002313- Implementation of PEP 341 - Unification of try/except and try/finally.
2314 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002315 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002316
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002317- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2318 now encodes backslash correctly.
2319
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002320- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2321
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002322- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002323 and long longs.
2324
Neal Norwitz67715f02005-11-09 06:59:35 +00002325- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002326 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002327 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002328
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002329- Replaced most Unicode charmap codecs with new ones using the
2330 new Unicode translate string feature in the builtin charmap
2331 codec; the codecs were created from the mapping tables available
2332 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2333 encodings now include a mapping for the Apple logo)
2334
Tim Peterse3547fd2005-12-16 23:13:57 +00002335- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002336
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002337- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002338
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002339- A new AST parser implementation was completed. The abstract
2340 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002341 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002342
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002343- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002344 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2345
Neal Norwitz708e51a2005-10-03 04:48:15 +00002346- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2347
Neal Norwitz11bd1192005-10-03 00:54:56 +00002348- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2349 Provide a warning when a directory is passed on the command line.
2350
Neal Norwitz40d37812005-10-02 01:48:49 +00002351- Fix segfault with invalid coding.
2352
2353- SF bug #772896: unknown encoding results in MemoryError.
2354
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002355- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002356 supported a __len__() method which evaluated to False when the iterator
2357 was empty.
2358
Guido van Rossum630db602005-09-20 18:49:54 +00002359- On 64-bit platforms, when __len__() returns a value that cannot be
2360 represented as a C int, raise OverflowError.
2361
Skip Montanarof8948ca2005-09-19 03:54:46 +00002362- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002363 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002364
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002365- SF bug #893549: parsing keyword arguments was broken with a few format
2366 codes.
2367
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002368- Changes donated by Elemental Security to make it work on AIX 5.3
2369 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2370 bug #105470: test_pwd fails on 64bit system (Opteron).
2371
Guido van Rossum539c6622005-09-14 17:49:54 +00002372- Changes donated by Elemental Security to make it work on HP-UX 11 on
2373 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2374
Georg Brandl4550b8d2005-08-26 06:43:52 +00002375- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002376 (fixes bug #1119418).
2377
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002378- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2379
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002380- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2381 exceptions that cause a function to exit.
2382
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002383- The implementation of set() and frozenset() was revised to use its
2384 own internal data structure. Memory consumption is reduced by 1/3
2385 and there are modest speed-ups as well. The API is unchanged.
2386
Tim Petersde7990b2005-07-17 23:45:23 +00002387- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2388
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002389- SF bug #1229429: PyObject_CallMethod failed to decrement some
2390 reference counts in some error exit cases.
2391
Tim Petersecc6e6a2005-07-10 22:30:55 +00002392- SF bug #1185883: Python's small-object memory allocator took over
2393 a block managed by the platform C library whenever a realloc specified
2394 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002395 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002396 portable way to copy data from the C-managed block into Python's
2397 small-object space without risking a memory fault. Python's small-object
2398 realloc now leaves such blocks under the control of the platform C
2399 realloc.
2400
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002401- SF bug #1232517: An overflow error was not detected properly when
2402 attempting to convert a large float to an int in os.utime().
2403
Raymond Hettinger3296e692005-06-29 23:29:56 +00002404- SF bug #1224347: hex longs now print with lowercase letters just
2405 like their int counterparts.
2406
Michael W. Hudson188d4362005-06-20 16:52:57 +00002407- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2408 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2409 interpreter states; back out that fix and do a better job (see
2410 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2411 for a longer write-up of the problem).
2412
Michael W. Hudsondf888462005-06-03 14:41:55 +00002413- SF patch #1180995: marshal now uses a binary format by default when
2414 serializing floats.
2415
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002416- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2417 the routines that promise to produce IEEE 754 binary representations
2418 of floats now simply copy bytes around.
2419
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002420- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2421 278.
2422
Brett Cannonc3647ac2005-04-26 03:45:26 +00002423- patch #1109424: int, long, float, complex, and unicode now check for the
2424 proper magic slot for type conversions when subclassed. Previously the
2425 magic slot was ignored during conversion. Semantics now match the way
2426 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002427 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002428 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002429 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002430
Barry Warsawc8d907c2005-04-19 23:43:40 +00002431- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2432 NULL, now raise an AttributeError when attempting to set or delete the
2433 attribute. Previously a TypeError was raised, but this was inconsistent
2434 with the equivalent pure-Python implementation.
2435
Michael W. Hudson774479c2005-04-18 08:46:17 +00002436- It is now safe to call PyGILState_Release() before
2437 PyEval_InitThreads() (note that if there is reason to believe there
2438 are multiple threads around you still must call PyEval_InitThreads()
2439 before using the Python API; this fix is for extension modules that
2440 have no way of knowing if Python is multi-threaded yet).
2441
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002442- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2443 disabled caused a crash.
2444
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002445- Bug #1165306: instancemethod_new allowed the creation of a method
2446 with im_class == im_self == NULL, which caused a crash when called.
2447
Tim Petersecc6e6a2005-07-10 22:30:55 +00002448- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002449 fixes the crash seen in bug #1165761
2450
Raymond Hettinger96229b12005-03-11 06:49:40 +00002451- Added two new builtins, any() and all().
2452
Brett Cannon409d8f22005-03-05 06:47:57 +00002453- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002454 (e.g., ``class C(): pass`` is no longer a syntax error).
2455 Patch #1176012 added support to the 'parser' module and 'compiler' package
2456 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002457
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002458- Patch #1115086: Support PY_LONGLONG in structmember.
2459
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002460- Bug #1155938: new style classes did not check that __init__() was
2461 returning None.
2462
Tim Petersecc6e6a2005-07-10 22:30:55 +00002463- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002464 ('\') with a specific error message.
2465
Martin v. Löwisff232d72005-03-03 09:24:38 +00002466- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2467
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002468- Bug #1124295: the __name__ attribute of file objects was
2469 inadvertently made inaccessible in restricted mode.
2470
Tim Petersecc6e6a2005-07-10 22:30:55 +00002471- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002472 an ferror() call.
2473
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002474- min() and max() now support key= arguments with the same meaning as in
2475 list.sort().
2476
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002477- The peephole optimizer now performs simple constant folding in expressions:
2478 (2+3) --> (5).
2479
Raymond Hettingera422c342005-01-11 03:03:27 +00002480- set and frozenset objects can now be marshalled. SF #1098985.
2481
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002482- Bug #1077106: Poor argument checking could cause memory corruption
2483 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002484
Jeremy Hyltonab630502005-02-04 18:44:06 +00002485- The parser did not complain about future statements in illegal
2486 positions. It once again reports a syntax error if a future
2487 statement occurs after anything other than a doc string.
2488
Neil Schemenauercf52c072005-08-12 17:34:58 +00002489- Change the %s format specifier for str objects so that it returns a
2490 unicode instance if the argument is not an instance of basestring and
2491 calling __str__ on the argument returns a unicode instance.
2492
Tim Petersf4e69282006-02-27 17:15:31 +00002493- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2494 current thread state when the auto-GIL-state machinery knows about
2495 it (since the thread state is being deleted, continuing to remember it
2496 can't help, but can hurt if another thread happens to get created with
2497 the same thread id).
2498
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002499Extension Modules
2500-----------------
2501

Neal Norwitz10be10c2006-03-16 06:50:13 +00002515 util, whatsound, whrandom, zmod
2516
2517- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2518
2519- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002520 is deprecated. The undocumented re.engine variable no longer exists.
2521
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002522- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2523 SS2 (single-shift 2) escape sequences correctly.
2524
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002525- The unicodedata module was updated to the 4.1 version of the Unicode
2526 database. The 3.2 version is still available as unicodedata.db_3_2_0
2527 for applications that require this specific version (such as IDNA).
2528
Neal Norwitzb62c4332006-03-04 18:35:47 +00002529- The timing module is no longer built by default. It was deprecated
2530 in PEP 4 in Python 2.0 or earlier.
2531
Guido van Rossum1968ad32006-02-25 22:38:04 +00002532- Patch 1433928: Added a new type, defaultdict, to the collections module.
2533 This uses the new __missing__ hook behavior added to dict (see above).
2534
Georg Brandldbd83392006-02-20 09:42:33 +00002535- Bug #854823: socketmodule now builds on Sun platforms even when
2536 INET_ADDRSTRLEN is not defined.
2537
Georg Brandlf4f44152006-02-18 22:29:33 +00002538- Patch #1393157: os.startfile() now has an optional argument to specify
2539 a "command verb" to invoke on the file.
2540
Neal Norwitz082b2df2006-02-07 07:04:46 +00002541- Bug #876637, prevent stack corruption when socket descriptor
2542 is larger than FD_SETSIZE.
2543
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002544- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2545 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2546 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

Martin v. Löwis57a34e82006-02-04 19:12:37 +00002548- Patch #1422385: The nis module now supports access to domains other
2549 than the system default domain.
2550
Martin v. Löwis14694662006-02-03 12:54:16 +00002551- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2552 are reported, the limit on path name lengths is removed, and stat reports
2553 WindowsError now (instead of OSError).
2554
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002555- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2630 the request code argument, which results in more C-like behaviour
2631 for large or negative values.
2632
Tim Petersecc6e6a2005-07-10 22:30:55 +00002633- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2648
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00002649- operator.itemgetter() and operator.attrgetter() now support retrieving

2674 args tuple returned by __reduce__().
2675
Raymond Hettingerb2594052004-12-05 09:25:51 +00002676- itertools.islice() now accepts None for the start and step arguments.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002689- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2690 been renamed to have only a single underscore prefix. This was done to
2691 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002692
Nick Coghlan43832302006-04-23 17:04:07 +00002693- PEP 338: new module runpy defines a run_module function to support
2694 executing modules which provide access to source code or a code object
2695 via the PEP 302 import mechanisms.
2696
Anthony Baxter93f5b932006-04-03 08:05:07 +00002697- The email module's parsedate_tz function now sets the daylight savings
2698 flag to -1 (unknown) since it can't tell from the date whether it should

2705 in attribute values.
2706
Anthony Baxterc51ee692006-04-01 00:57:31 +00002707- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002708 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002709 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002710 module will not be built.
2711
Tim Petersc17976e2006-04-01 00:26:53 +00002712- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2713 aren't officially supported here, and trying to use them will probably
2714 raise an exception some day. But dicts have been allowed, and "mostly
2715 worked", so support for them won't go away without warning.
2716
Georg Brandl338ef7d2006-03-31 18:42:16 +00002717- Bug #1445068: getpass.getpass() can now be given an explicit stream
2718 argument to specify where to write the prompt.
2719
Georg Brandl22ec80b2006-03-31 18:25:44 +00002720- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2727
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002728- Queue.Queue objects now support .task_done() and .join() methods
2729 to make it easier to monitor when daemon threads have completed
2730 processing all enqueued tasks. Patch #1455676.
2731

2735
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002736- email 4.0 package now integrated. This is largely the same as the email 3.0
2737 package that was included in Python 2.3, except that PEP 8 module names are
2738 now used (e.g. mail.message instead of email.Message). The MIME classes
2739 have been moved to a subpackage (e.g. email.mime.text instead of
2740 email.MIMEText). The old names are still supported for now. Several
2741 deprecated Message methods have been removed and lots of bugs have been
2742 fixed. More details can be found in the email package documentation.
2743
Walter Dörwald40108c92006-03-27 08:15:44 +00002744- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2745 (a subclass of tuple) that provides incremental decoders and encoders
2746 (a way to use stateful codecs without the stream API). Python functions
2747 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2748 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2749 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002750
Walter Dörwald067db482006-03-15 22:17:27 +00002751- Patch #1359365: Calling next() on a closed StringIO.String object raises
2752 a ValueError instead of a StopIteration now (like file and cString.String do).
2753 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2754 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002755
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002756- A regrtest option -w was added to re-run failed tests in verbose mode.

2766
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002767- PEP 343: new module contextlib.py defines decorator @contextmanager
2768 and helpful context managers nested() and closing().
2769
Martin v. Löwis415ed932006-02-27 19:56:30 +00002770- The compiler package now supports future imports after the module docstring.
2771

2774
Georg Brandlc98eeed2006-02-19 14:57:47 +00002775- Patch #1215184: FileInput now can be given an opening hook which can

Martin v. Löwis3e865952006-01-24 15:51:21 +00002804 specifications, raises IOErrors when proxies for unsupported protocols
2805 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002828 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2829 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2830 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2831 Ronald L. Rivest offered this advice for Python:
2832
2833 "The consensus of researchers in this area (at least as
2834 expressed at the NIST Hash Function Workshop 10/31/05),
2835 is that SHA-256 is a good choice for the time being, but
2836 that research should continue, and other alternatives may
2837 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002838
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002839- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandlb9256022005-08-24 18:46:39 +00002885- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
2886 ContentTooShortException, when the actually downloaded size does not
2887 match the Content-Length header.
2888
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +00002889- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
2890

2892 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002893 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002894

2916 to W3C name (404 -> 'Not Found'). RFE #1216944.
2917
Georg Brandl9e43acf2005-07-04 17:16:07 +00002918- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2919 as this can cause problems with apps closing all file descriptors.

2932 Bug #1224621.
2933
Raymond Hettinger68c04532005-06-10 11:05:19 +00002934- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002935 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002936 the generate_tokens() function now accepts a callable argument that
2937 terminates by raising StopIteration.
2938
Georg Brandl9166e1a2005-06-04 09:20:03 +00002939- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2947 class at all.
2948
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002949- distutils.commands.upload was added to support uploading distribution
2950 files to PyPI.
2951
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002952- distutils.commands.register now encodes the data as UTF-8 before posting
2953 them to PyPI.
2954
Raymond Hettinger267b8682005-03-27 10:47:39 +00002955- decimal operator and comparison methods now return NotImplemented
2956 instead of raising a TypeError when interacting with other types. This
2957 allows other classes to implement __radd__ style methods and have them
2958 work as expected.
2959
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002960- Bug #1163325: Decimal infinities failed to hash. Attempting to
2961 hash a NaN raised an InvalidOperation instead of a TypeError.
2962
Tim Petersecc6e6a2005-07-10 22:30:55 +00002963- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2997
Guido van Rossumd0641422005-02-03 15:01:24 +00002998- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2999 disables recursive traversal through instance attributes, which can
3000 be exploited in various ways.
3001
Tim Peterse3547fd2005-12-16 23:13:57 +00003002- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003003 flags on the HTTP listening socket.
3004
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003005- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3006 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3007
Fred Drakefbdeaad2006-07-29 16:56:15 +00003008- Patches #893642, #1039083: add allow_none, encoding arguments to
3009 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003010
Martin v. Löwis1d11de62005-01-29 13:29:23 +00003011- Bug #1110478: Revert os.environ.update to do putenv again.
3012
Thomas Hellerd6c6e222005-01-20 19:20:16 +00003013- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3014
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003015- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3016
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003017- Enhancements to the csv module:
3018
3019 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003020 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003021 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003022 + Dialect parameter parsing has been re-implemented to improve error
3023 reporting.
3024 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3025 dictates.
3026 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003027 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003028 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003029 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3030 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003031 + reader now allows \r characters to be quoted (previously it only allowed
3032 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003033 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003034 + Dialect classes passed to the module are no longer instantiated by
3035 the module before being parsed (the former validation scheme required
3036 this, but the mechanism was unreliable).
3037 + The dialect registry now contains instances of the internal
3038 C-coded dialect type, rather than references to python objects.
3039 + the internal c-coded dialect type is now immutable.
3040 + register_dialect now accepts the same keyword dialect specifications
3041 as the reader and writer, allowing the user to register dialects
3042 without first creating a dialect class.
3043 + a configurable limit to the size of parsed fields has been added -
3044 previously, an unmatched quote character could result in the entire
3045 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003046 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003047 the parser field size limit (returning the former limit). The initial
3048 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003049 + A line_num attribute has been added to the reader object, which tracks
3050 the number of lines read from the source iterator. This is not
3051 the same as the number of records returned, as records can span
3052 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003053 + reader and writer objects were not being registered with the cyclic-GC.
3054 This has been fixed.
3055
Brett Cannone6539c42005-01-08 02:43:53 +00003056- _DummyThread objects in the threading module now delete self.__block that is
3057 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3058 lock primitives tend to be limited in number and thus should not be wasted on
3059 a _DummyThread object. Fixes bug #1089632.
3060
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003061- The imghdr module now detects Exif files.
3062
Raymond Hettinger6065d322004-12-20 23:51:53 +00003063- StringIO.truncate() now correctly adjusts the size attribute.
3064 (Bug #951915).
3065
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003066- locale.py now uses an updated locale alias table (built using
3067 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3068 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003069 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003070
Raymond Hettinger3557f422004-12-07 12:02:02 +00003071- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3072
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003073- the pickle module no longer accepts the deprecated None option in the
3074 args tuple returned by __reduce__().
3075
Brett Cannon84667c02004-12-07 03:25:18 +00003076- optparse now optionally imports gettext. This allows its use in setup.py.
3077
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003078- the pickle module no longer uses the deprecated bin parameter.
3079
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003080- the shelve module no longer uses the deprecated binary parameter.
3081
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003082- the pstats module no longer uses the deprecated ignore() method.
3083
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003084- the filecmp module no longer uses the deprecated use_statcache argument.
3085
Raymond Hettinger664347b2004-12-04 21:21:53 +00003086- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3087 extended or overridden by subclasses. Formerly, the subclassed method would
3088 be ignored by the rest of the module. (Bug #1078905).
3089
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003090- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003091 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003092
Walter Dörwald36733692004-12-22 12:50:50 +00003093- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3094 once when a size argument is given. This prevents a buffer overflow in the
3095 tokenizer with very long source lines.
3096
Barry Warsaw538561e2006-01-01 21:48:54 +00003097- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3098 immediately after creating the object, without any intervening
3099 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003100
Skip Montanaro05885812005-01-16 20:48:27 +00003101- The reconvert.quote function can now emit triple-quoted strings. The
3102 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003103
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003104- ``UserString.MutableString`` now supports negative indices in
3105 ``__setitem__`` and ``__delitem__``
3106
Greg Ward40407942005-03-05 02:53:17 +00003107- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3108 correctly.
3109
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003110- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3111 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3112 character even if the user has passed a size parameter to get a proper
3113 line ending. Remove the special handling of a "\r\n" that has been split
3114 between two lines.
3115
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003116- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3117 about illegal code points. The codec now supports PEP 293 style error
3118 handlers.
3119
Walter Dörwald78a78b02005-09-01 12:04:29 +00003120- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003121 from the input stream, so that the output is a byte string in the correct
3122 encoding instead of a unicode string.

Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003124- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3125 considering it exactly like a '*'.
3126
Walter Dörwald007f8df2005-10-09 19:42:27 +00003127- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3128 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003129
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003130- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3131
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003132- Patch #1413711: Certain patterns of differences were making difflib
3133 touch the recursion limit.
3134
Walter Dörwald58917a62006-03-31 15:26:22 +00003135- Bug #947906: An object oriented interface has been added to the calendar
3136 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003137 called as a script (e.g. via ``python -mcalendar``). Localized month and
3138 weekday names can be ouput (even if an exotic encoding is used) using
3139 special classes that use unicode.

3148
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003149- Build support for Win64-AMD64 was added.
3150
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003151- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3152
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003153- Patch #881820: look for openpty and forkpty also in libbsd.
3154
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003155- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3156 The zlib module is now builtin on Windows.
3157
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003158- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3159
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003160- Bug #1189330: configure did not correctly determine the necessary
3161 value of LINKCC if python was built with GCC 4.0.
3162
Trent Mick8321b422005-07-26 02:29:21 +00003163- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3164 vulnerability in zlib 1.2.1 and 1.2.2.
3165
Brett Cannon08cd5982005-04-24 22:26:38 +00003166- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3167 flags that change binary compatibility. Changes were also made to
3168 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003169 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003170
Bob Ippolitoed233462005-03-29 13:47:59 +00003171- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3172 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3173 no longer exists). This configure patch makes things right.
3174
Martin v. Löwise2713be2005-03-08 15:03:08 +00003175- Bug #1158607: Build with --disable-unicode again.
3176
Brett Cannon46d96232005-02-16 00:07:19 +00003177- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3178 defined. Discovered as a result of not being able to build on OS X.
3179
Brett Cannon516592f2004-12-07 00:42:59 +00003180- setup.py now uses the directories specified in LDFLAGS using the -L option
3181 and in CPPFLAGS using the -I option for adding library and include
3182 directories, respectively, for compiling extension modules against. This has
3183 led to the core being compiled using the values in CPPFLAGS. It also removes
3184 the need for the special-casing of both DarwinPorts and Fink for darwin since
3185 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3186 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3187 Fink, ``-I/opt/local/include`` for DarwinPorts).
3188
Brett Cannon43802422005-02-10 20:48:03 +00003189- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3190 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3191 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3192 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003194C API
3195-----
3196
Tim Petersc9d78aa2006-03-26 23:27:58 +00003197- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3198 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3199 is obtained via the ``PyObject_`` family, it must be released via the
3200 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3201 always been officially true, but when Python's small-object allocator was
3202 introduced, an attempt was made to cater to a few extension modules
3203 discovered at the time that obtained memory via ``PyObject_New`` but
3204 released it via ``PyMem_DEL``. It's years later, and if such code still
3205 exists it will fail now (probably with segfaults, but calling wrong
3206 low-level memory management functions can yield many symptoms).
3207
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003208- Added a C API for set and frozenset objects.
3209

3211
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003212- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3213 mapping argument now. This string is used as a mapping table. Byte values
3214 greater than the length of the string and 0xFFFE are treated as undefined
3215 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003222
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003223- Patch #1276356: New resource "urlfetch" is implemented. This enables
3224 even impatient people to run tests that require remote files.
