Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +00007What's New in Python 2.5.3?
8=============================

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

75-------
76
Brett Cannonff931572008-07-13 01:20:19 +000077- Issue #3339: dummy_thread.acquire() could return None which is not a valid
78 return value.
79
Raymond Hettinger75ee9eb2008-06-16 01:49:18 +000080- Issue #3116 and #1792: Fix quadratic behavior in marshal.dumps().
81
Thomas Hellerf3bb2832008-04-25 19:55:19 +000082- Issue #2682: ctypes callback functions no longer contain a cyclic
83 reference to themselves.
84
Amaury Forgeot d'Arc8d904c32008-04-22 21:17:18 +000085- Issue #2670: Fix a failure in urllib2.build_opener(), when passed two
86 handlers that derive the same default base class.
87
Amaury Forgeot d'Arc198e3532008-03-27 23:41:59 +000088- Issue #2495: tokenize.untokenize now inserts a space between two consecutive
89 string literals; previously, ["" ""] was rendered as [""""], which is
90 incorrect python code.
91
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +000092- Issue #2482: Make sure that the coefficient of a Decimal is always
93 stored as a str instance, not as a unicode instance. This ensures
94 that str(Decimal) is always an instance of str. This fixes a
95 regression from Python 2.5.1 to Python 2.5.2.
96
Mark Dickinson26c25d92008-03-25 14:35:25 +000097- Issue #2478: fix failure of decimal.Decimal(0).sqrt()
98
Georg Brandld9b9d682008-03-21 20:01:55 +000099- Issue #2432: give DictReader the dialect and line_num attributes
100 advertised in the docs.
101
Gregory P. Smitheff5a4e2008-03-18 19:24:40 +0000102- Issue #1747858: Fix chown to work with large uid's and gid's on 64-bit
103 platforms.
104
Georg Brandlab61dce2008-03-06 07:46:26 +0000105- Bug #2220: handle rlcompleter attribute match failure more gracefully.
106
Martin v. Löwis0e305552008-03-06 07:14:26 +0000107- Bug #1725737: In distutil's sdist, exclude RCS, CVS etc. also in the
108 root directory, and also exclude .hg, .git, .bzr, and _darcs.
109
Andrew M. Kuchling37d4f7b2008-02-23 19:06:54 +0000110- Bug #1389051: imaplib causes excessive memory fragmentation when reading
111 large messages.
112

Andrew M. Kuchling05a19a52008-02-23 17:21:44 +0000116- Bug #1433694: minidom's .normalize() failed to set .nextSibling for
117 last child element.
118
Gregory P. Smith26660402008-06-01 23:44:46 +0000119- Issue #2791: subprocess.Popen.communicate explicitly closes its
120 stdout and stderr fds rather than leaving them open until the
121 instance is destroyed.
122
Gregory P. Smithf8f30fa2008-07-06 04:04:07 +0000123- Issue #2632: Prevent socket.read(bignumber) from over allocating memory
124 in the common case when the data is returned from the underlying socket
125 in increments much smaller than bignumber.
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +0000126

186
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000187- Issue #1920: "while 0" statements were completely removed by the compiler,
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000188 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000189 the condition is false. Now the compiler correctly emits bytecode for the
190 "else" suite.
191

199
Christian Heimesd2f4cb82008-01-23 14:20:41 +0000200- Bug #1915: Python compiles with --enable-unicode=no again. However

1153
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001154- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001155 compared equal or unequal to a string and a UnicodeDecodeError
1156 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001157
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001158 Instead, the equal (==) and unequal (!=) comparison operators will
1159 now issue a UnicodeWarning and interpret the two objects as
1160 unequal. The UnicodeWarning can be filtered as desired using
1161 the warning framework, e.g. silenced completely, turned into an
1162 exception, logged, etc.
1163
1164 Note that compare operators other than equal and unequal will still
1165 raise UnicodeDecodeError exceptions as they've always done.

Marc-André Lemburg757ea272006-08-14 11:44:34 +00001167- Fix segfault when doing string formatting on subclasses of long.
1168
1169- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1170 with new-style classes.
1171
1172- Fix bug related to __len__ functions returning negative values with
1173 classic classes.
1174
1175- Patch #1538606, Fix __index__() clipping. There were some problems
1176 discovered with the API and how integers that didn't fit into Py_ssize_t
1177 were handled. This patch attempts to provide enough alternatives
1178 to effectively use __index__.
1179
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001180- Bug #1536021: __hash__ may now return long int; the final hash
1181 value is obtained by invoking hash on the long int.
1182
Thomas Hellerab1049c2006-08-08 17:37:00 +00001183- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1184
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001185- Bug #1535165: fixed a segfault in input() and raw_input() when
1186 sys.stdin is closed.
1187
Thomas Heller74d36f02006-08-04 18:17:40 +00001188- On Windows, the PyErr_Warn function is now exported from
1189 the Python dll again.
1190
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001191- Bug #1191458: tracing over for loops now produces a line event
1192 on each iteration. Fixing this problem required changing the .pyc
1193 magic number. This means that .pyc files generated before 2.5c1
1194 will be regenerated.
1195
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001196- Bug #1333982: string/number constants were inappropriately stored
1197 in the byte code and co_consts even if they were not used, ie
1198 immediately popped off the stack.
1199
Georg Brandle9462c72006-08-04 18:03:37 +00001200- Fixed a reference-counting problem in property().

1205
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001206- Fix a bug in the ``compiler`` package that caused invalid code to be
1207 generated for generator expressions.
1208
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001209- The distutils version has been changed to 2.5.0. The change to
1210 keep it programmatically in sync with the Python version running
1211 the code (introduced in 2.5b3) has been reverted. It will continue
1212 to be maintained manually as static string literal.
1213
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001214- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001215 and this cannot be converted to the required C type, an exception is
1216 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001217 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001218
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001219- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001220 an exception.
1221
Tim Peterscbdd3502006-09-05 01:47:53 +00001222- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001223 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001224 workarounds for clocks with low resolution, to stop the code yielding
1225 duplicate UUIDs.
1226
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001227- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1228 before raising SystemExit, allowing IDLE to honor quit() and exit().
1229
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001230- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1231
Georg Brandl7a1af772006-08-14 21:55:28 +00001232- Patch #1536071: trace.py should now find the full module name of a
1233 file correctly even on Windows.
1234
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001235- logging's atexit hook now runs even if the rest of the module has
1236 already been cleaned up.
1237
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001238- Bug #1112549, fix DoS attack on cgi.FieldStorage.

Georg Brandl3335a7a2006-08-14 21:42:55 +00001254- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1255 raises the correct exceptions.
1256
Thomas Heller1ce433e2006-08-14 16:20:04 +00001257- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1258 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1259
Thomas Heller86720042006-08-14 11:17:48 +00001260- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1261 uses the _as_parameter_ attribute when objects are passed to foreign
1262 function calls. The ctypes version number was changed to 1.0.1.
1263
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001264- Bug #1530559, struct.pack raises TypeError where it used to convert.
1265 Passing float arguments to struct.pack when integers are expected
1266 now triggers a DeprecationWarning.

Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001292- Bug #1535502, build _hashlib on Windows, and use masm assembler
1293 code in OpenSSL.
1294
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001295- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

1301-----
1302
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001303- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1304
Tim Peters4643c2f2006-08-10 22:45:34 +00001305- Bug #1069160. Internal correctness changes were made to
1306 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1307 the documentation was changed to state that the return value
1308 is always 1 (normal) or 0 (if the specified thread wasn't found).

Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001314*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001315
1316Core and builtins
1317-----------------
1318
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001319- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001320 returned a long (see PEP 353).
1321
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001322- Bug #1515471: string.replace() accepts character buffers again.
1323
Neal Norwitz07aadb12006-07-30 06:55:48 +00001324- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1325 This provides the proper warning for struct.pack().
1326 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1327
Neal Norwitz0d62a062006-07-30 06:53:31 +00001328- Patch #1531113: Fix augmented assignment with yield expressions.
1329 Also fix a SystemError when trying to assign to yield expressions.
1330
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001331- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1332 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1333 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1334 excessive filesystem operations during imports.
1335
Tim Petersbc24eee2006-07-27 01:14:53 +00001336- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1337 operations on signed longs that are formally undefined by C.
1338 Unfortunately, at least one compiler now cares about that, so complicated
1339 the code to make that compiler happy again.
1340
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001341- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1342
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001343- Patch #1232023: Stop including current directory in search
1344 path on Windows.
1345
Neal Norwitze1fdb322006-07-21 05:32:28 +00001346- Fix some potential crashes found with failmalloc.
1347
Neal Norwitze7563102006-07-17 01:00:16 +00001348- Fix warnings reported by Klocwork's static analysis tool.
1349
Neal Norwitz84be93b2006-07-16 01:50:38 +00001350- Bug #1512814, Fix incorrect lineno's when code within a function
1351 had more than 255 blank lines.
1352
Georg Brandl9dceedb2006-07-12 15:31:17 +00001353- Patch #1521179: Python now accepts the standard options ``--help`` and
1354 ``--version`` as well as ``/?`` on Windows.
1355
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001356- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001357 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001358 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001359
Tim Peters112aad32006-07-19 00:03:19 +00001360- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001361 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001362 new ``sys._current_frames()`` returns a dictionary with one entry,
1363 mapping the faux "thread id" 0 to the current frame.
1364
Ronald Oussoren3075e162006-07-25 20:28:55 +00001365- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001366
Ronald Oussoren3075e162006-07-25 20:28:55 +00001367
Neal Norwitza1f10902006-07-12 07:28:29 +00001368Library
1369-------
1370
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001371- Correction of patch #1455898: In the mbcs decoder, set final=False
1372 for stream decoder, but final=True for the decode function.
1373
Georg Brandl07fec3a2006-08-01 18:49:24 +00001374- os.urandom no longer masks unrelated exceptions like SystemExit or
1375 KeyboardInterrupt.
1376
Tim Peters4643c2f2006-08-10 22:45:34 +00001377- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001378 shutil.copytree on Windows
1379
Georg Brandle34ac7c2006-07-30 11:07:23 +00001380- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1381 refers to file descriptors, not file objects.
1382
Tim Peterscbdd3502006-09-05 01:47:53 +00001383- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001384 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001385 #1513611, and probably others.
1386
Georg Brandledd9b0d2006-07-29 09:33:26 +00001387- Bug #1441397: The compiler module now recognizes module and function
1388 docstrings correctly as it did in Python 2.4.
1389
Tim Peters6f681472006-07-27 23:44:37 +00001390- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1391 lost that tests are sorted by name before being run. This rarely
1392 matters for well-written tests, but can create baffling symptoms if
1393 side effects from one test to the next affect outcomes. ``DocTestFinder``
1394 has been changed to sort the list of tests it returns.
1395
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001396- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001397 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001398
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001399- Bug #978833: Really close underlying socket in _socketobject.close.
1400
Georg Brandldb232dc2006-08-20 13:15:43 +00001401- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1402 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001403
Georg Brandlcf0c1722006-07-26 07:23:32 +00001404- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1405 to recursive calls and call it with the failing package name.
1406
Martin v. Löwis0b483032006-07-25 09:53:12 +00001407- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1408
Georg Brandlc13c34c2006-07-24 14:09:56 +00001409- Patch #1515343: Fix printing of deprecated string exceptions with a
1410 value in the traceback module.
1411
Greg Ward48fae7a2006-07-23 16:05:51 +00001412- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1413
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001414- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1415
Brett Cannoncaebe222006-07-18 04:41:36 +00001416- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1417 argument tuple. For arguments where zero is illegal, the value is forced to
1418 the minimum value that is correct. This is to support an undocumented but
1419 common way people used to fill in inconsequential information in the time
1420 tuple pre-2.4.
1421
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001422- Patch #1220874: Update the binhex module for Mach-O.
1423
Barry Warsawb110bad2006-07-21 14:51:07 +00001424- The email package has improved RFC 2231 support, specifically for
1425 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1426 (name*0=<blah>) parameter continuations. This may change the types of
1427 values returned from email.message.Message.get_param() and friends.
1428 Specifically in some cases where non-encoded continuations were used,
1429 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1430 will just return the string (since non-encoded continuations don't have
1431 charset and language parts).
1432
1433 Also, whereas % values were decoded in all parameter continuations, they are
1434 now only decoded in encoded parameter parts.
1435
Ronald Oussoren3075e162006-07-25 20:28:55 +00001436- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1437
1438- Bug #1517996: IDLE now longer shows the default Tk menu when a
1439 path browser, class browser or debugger is the frontmost window on MacOS X
1440
Barry Warsaw00decd72006-07-27 23:43:15 +00001441- Patch #1520294: Support for getset and member descriptors in types.py,
1442 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1443 of an object against these built-in types and more importantly, for getting
1444 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitz9b0ca792006-08-02 06:46:21 +00001450- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1451 a socket operation on a socket with a timeout, the exception will be
1452 caught correctly. Previously, the exception was not caught.
1453
Thomas Heller1393d6a2006-07-28 21:43:20 +00001454- Patch #1529514: The _ctypes extension is now compiled on more
1455 openbsd target platforms.
1456
Tim Peters9cab5932006-07-28 00:30:00 +00001457- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1458 a memory leak, affecting pickles and deep copies.
1459
Tim Petersbc24eee2006-07-27 01:14:53 +00001460- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001461 Paul Eggert.
1462
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001463- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1464
Thomas Hellerce049a02006-07-14 17:51:14 +00001465- Patch #1521817: Index range checking on ctypes arrays containing
1466 exactly one element enabled again. This allows iterating over these
1467 arrays, without the need to check the array size before.
1468
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001469- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001470 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001471 /dev/null in certain cases; this is now fixed.
1472
Thomas Heller47d7a062006-07-12 08:43:47 +00001473- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1474 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001475
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001476- Because of a misspelled preprocessor symbol, ctypes was always
1477 compiled without thread support; this is now fixed.
1478
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001479- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1480 methods now allow their database parameter to be None as the
1481 sleepycat API allows.
1482
Matt Flemingec926502006-07-28 11:27:27 +00001483- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1484 bluetooth API compared with Linux and FreeBSD.
1485
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001486Tests
1487-----
1488
1489- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1490 how long the test file should take to play. Now accepts taking 2.93 secs
1491 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1492
Georg Brandl4793aa32006-07-28 18:31:39 +00001493- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1494 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1495 run via ``regrtest.py``. Now they do.

Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001497Build
1498-----
1499
1500- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1501
Ronald Oussoren26cad082006-08-01 21:00:57 +00001502Mac
1503---
1504
1505- PythonLauncher now works correctly when the path to the script contains
1506 characters that are treated specially by the shell (such as quotes).
1507
1508- Bug #1527397: PythonLauncher now launches scripts with the working directory
1509 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001510 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001511 expect.

1519Core and builtins
1520-----------------
1521
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001522- Bug #1441486: The literal representation of -(sys.maxint - 1)
1523 again evaluates to a int object, not a long.
1524
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001525- Bug #1501934: The scope of global variables that are locally assigned
1526 using augmented assignment is now correctly determined.
1527
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001528- Bug #927248: Recursive method-wrapper objects can now safely
1529 be released.
1530
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001531- Bug #1417699: Reject locale-specific decimal point in float()
1532 and atof().
1533
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001534- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1535 omit a default "error" argument for NULL pointer. This allows
1536 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001537
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001538- Bug #1519018: 'as' is now validated properly in import statements.
1539
Neal Norwitz28746ab2006-07-09 22:14:42 +00001540- On 64 bit systems, int literals that use less than 64 bits are
1541 now ints rather than longs.
1542
Neal Norwitzed657552006-07-10 00:04:44 +00001543- Bug #1512814, Fix incorrect lineno's when code at module scope
1544 started after line 256.
1545
Tim Peters32a83612006-07-10 21:08:24 +00001546- New function ``sys._current_frames()`` returns a dict mapping thread
1547 id to topmost thread stack frame. This is for expert use, and is
1548 especially useful for debugging application deadlocks. The functionality
1549 was previously available in Fazal Majid's ``threadframe`` extension
1550 module, but it wasn't possible to do this in a wholly threadsafe way from
1551 an extension.
1552

1560
Tim Peters32a83612006-07-10 21:08:24 +00001561- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001562 environment variable to be set in order to the SDK environment
1563 for finding the compiler, include files, etc.

1568
Thomas Woutersadd19112006-07-05 11:03:49 +00001569- string.Template() now correctly handles tuple-values. Previously,
1570 multi-value tuples would raise an exception and single-value tuples would
1571 be treated as the value they contain, instead.
1572
Martin v. Löwisede77f52006-07-03 13:01:35 +00001573- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1574 even if some data are received.
1575
Martin v. Löwis45482392006-07-03 12:28:58 +00001576- Bug #1267547: Put proper recursive setup.py call into the
1577 spec file generated by bdist_rpm.
1578
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001579- Bug #1514693: Update turtle's heading when switching between
1580 degrees and radians.
1581
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001582- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001583 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001584
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001585- Bug #1514703: Only setup canvas window in turtle when the canvas
1586 is created.
1587
Martin v. Löwis7596e832006-07-01 15:33:37 +00001588- Bug #1513223: .close() of a _socketobj now releases the underlying
1589 socket again, which then gets closed as it becomes unreferenced.

1592 attribute values.
1593
1594- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1595 sgmllib ('[' and ']' were not accepted).
1596
Georg Brandl1be63af2006-06-28 20:23:25 +00001597- Fix a bug in the turtle module's end_fill function.
1598
Brett Cannon53ab5b72006-06-22 16:49:14 +00001599- Bug #1510580: The 'warnings' module improperly required that a Warning
1600 category be either a types.ClassType and a subclass of Warning. The proper
1601 check is just that it is a subclass with Warning as the documentation states.
1602
Georg Brandlad29e632006-06-21 17:45:17 +00001603- The compiler module now correctly compiles the new try-except-finally
1604 statement (bug #1509132).
1605
Neal Norwitz60373cd2006-06-22 06:30:50 +00001606- The wsgiref package is now installed properly on Unix.
1607
Vinay Sajip28e57612006-07-01 10:45:20 +00001608- A bug was fixed in logging.config.fileConfig() which caused a crash on
1609 shutdown when fileConfig() was called multiple times.
1610
Gerhard Häring762fbd32006-07-02 17:48:30 +00001611- The sqlite3 module did cut off data from the SQLite database at the first
1612 null character before sending it to a custom converter. This has been fixed
1613 now.
1614
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001615Extension Modules
1616-----------------
1617
Tim Peters112aad32006-07-19 00:03:19 +00001618- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1619 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1620 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001621
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001622- Assigning None to pointer type fields in ctypes structures possible
1623 overwrote the wrong fields, this is fixed now.
1624
1625- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1626 on non-Windows platforms.
1627
1628- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1629 integer or long, without range checking.
1630
1631- Patch #1517790: It is now possible to use custom objects in the ctypes
1632 foreign function argtypes sequence as long as they provide a from_param
1633 method, no longer is it required that the object is a ctypes type.
1634
1635- The '_ctypes' extension module now works when Python is configured
1636 with the --without-threads option.
1637
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001638- Bug #1513646: os.access on Windows now correctly determines write
1639 access, again.
1640
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001641- Bug #1512695: cPickle.loads could crash if it was interrupted with
1642 a KeyboardInterrupt.
1643
Neal Norwitza12aa882006-07-06 06:45:08 +00001644- Bug #1296433: parsing XML with a non-default encoding and
1645 a CharacterDataHandler could crash the interpreter in pyexpat.
1646
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001647- Patch #1516912: improve Modules support for OpenVMS.
1648
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001649Build
1650-----
1651
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001652- Automate Windows build process for the Win64 SSL module.
1653
Tim Peters32a83612006-07-10 21:08:24 +00001654- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001655 Previously, the slight difference could cause compilation errors of the
1656 'zlib' module on systems with more than one version of zlib.
1657
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001658- The MSI compileall step was fixed to also support a TARGETDIR
1659 with spaces in it.
1660
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001661- Bug #1517388: sqlite3.dll is now installed on Windows independent

Neal Norwitz3b6b8012006-06-27 04:12:58 +00001665 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +00001666
Neal Norwitzb15ac312006-06-29 04:10:08 +00001667Tests
1668-----
1669
1670- Call os.waitpid() at the end of tests that spawn child processes in order
1671 to minimize resources (zombies).
1672
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001673Documentation
1674-------------
1675
Nick Coghlan2d792252006-07-06 13:47:18 +00001676- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1677 documentation for the warnings module.
1678
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001679- Patch #1509163: MS Toolkit Compiler no longer available.
1680

Anthony Baxter51bcb682006-04-05 14:51:42 +00001688
1689Core and builtins
1690-----------------
1691
Georg Brandla56b9152006-06-19 06:35:54 +00001692- Patch #1507676: Error messages returned by invalid abstract object operations
1693 (such as iterating over an integer) have been improved and now include the
1694 type of the offending object to help with debugging.
1695
Brett Cannonea3912b2006-06-13 21:46:41 +00001696- Bug #992017: A classic class that defined a __coerce__() method that returned
1697 its arguments swapped would infinitely recurse and segfault the interpreter.
1698
Neal Norwitz909eb122006-06-12 02:13:21 +00001699- Fix the socket tests so they can be run concurrently.
1700
Neal Norwitzb9845e72006-06-12 02:11:18 +00001701- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001702 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001703
Brett Cannon22565aa2006-06-09 22:31:23 +00001704- Bug #532646: object.__call__() will continue looking for the __call__
1705 attribute on objects until one without one is found. This leads to recursion
1706 when you take a class and set its __call__ attribute to an instance of the
1707 class. Originally fixed for classic classes, but this fix is for new-style.
1708 Removes the infinite_rec_3 crasher.
1709
Georg Brandl24250812006-06-09 18:45:48 +00001710- The string and unicode methods startswith() and endswith() now accept
1711 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1712
Brett Cannonde3b0522006-06-08 17:00:45 +00001713- Buffer objects, at the C level, never used the char buffer
1714 implementation even when the char buffer for the wrapped object was
1715 explicitly requested (originally returned the read or write buffer).
1716 Now a TypeError is raised if the char buffer is not present but is
1717 requested.
1718
Georg Brandlddbaa662006-06-04 21:56:52 +00001719- Patch #1346214: Statements like "if 0: suite" are now again optimized
1720 away like they were in Python 2.4.
1721
Georg Brandlb7c8f542006-05-27 12:30:25 +00001722- Builtin exceptions are now full-blown new-style classes instead of
1723 instances pretending to be classes, which speeds up exception handling
1724 by about 80% in comparison to 2.5a2.
1725
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001726- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1727 Unicode 4.1.
1728
Georg Brandlf4ef1162006-05-26 18:03:31 +00001729- Patch #921466: sys.path_importer_cache is now used to cache valid and
1730 invalid file paths for the built-in import machinery which leads to
1731 fewer open calls on startup.
1732
Tim Peters696cf432006-05-24 21:10:40 +00001733- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1734 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1735 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1736 the number of input digits (it was and remains linear-time for bases
1737 2, 4, 8, 16 and 32).
1738
Tim Petersb713ec22006-05-23 18:45:30 +00001739- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1740 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1741 an integer close to ``sys.maxint``. This was repaired by patch
1742 #1335972, which also gives a nice speedup.

Richard Jonescebbefc2006-05-23 18:28:17 +00001744- Patch #1337051: reduced size of frame objects.
1745
1746- PyErr_NewException now accepts a tuple of base classes as its
1747 "base" parameter.
1748
Richard Jones7c88dcc2006-05-23 10:37:38 +00001749- Patch #876206: function call speedup by retaining allocated frame
1750 objects.
1751
Georg Brandl7b90e162006-05-18 07:01:27 +00001752- Bug #1462152: file() now checks more thoroughly for invalid mode
1753 strings and removes a possible "U" before passing the mode to the
1754 C library function.
1755
Neal Norwitz1004a532006-05-15 07:17:23 +00001756- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1757
Neal Norwitz373f0a72006-05-15 07:04:36 +00001758- Bug #1487966: Fix SystemError with conditional expression in assignment
1759
Martin v. Löwis879768d2006-05-11 13:28:43 +00001760- WindowsError now has two error code attributes: errno, which carries
1761 the error values from errno.h, and winerror, which carries the error
1762 values from winerror.h. Previous versions put the winerror.h values
1763 (from GetLastError()) into the errno attribute.
1764
Martin v. Löwis77736712006-05-04 05:51:03 +00001765- Patch #1475845: Raise IndentationError for unexpected indent.
1766
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001767- Patch #1479181: split open() and file() from being aliases for each other.
1768
Tim Peters44bd9862006-06-01 13:49:23 +00001769- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1770 methods were always silently ignored by dictionaries when comparing keys.
1771 They are now passed through (except when using the C API function
1772 ``PyDict_GetItem()``, whose semantics did not change).
1773
1774- Bug #1456209: In some obscure cases it was possible for a class with a
1775 custom ``__eq__()`` method to confuse dict internals when class instances
1776 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1777 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001779Extension Modules
1780-----------------
1781
Trent Mick960a3f82006-06-28 20:30:41 +00001782- Bug #1295808: expat symbols should be namespaced in pyexpat
1783
1784- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1785
Brett Cannon6ee7d012006-06-08 16:23:04 +00001786- Change binascii.hexlify to accept a read-only buffer instead of only a char
1787 buffer and actually follow its documentation.
1788
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001789- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1790
Nick Coghlanc649ec52006-05-29 12:43:05 +00001791- Patch #1478788 (modified version): The functional extension module has
1792 been renamed to _functools and a functools Python wrapper module added.
1793 This provides a home for additional function related utilities that are
1794 not specifically about functional programming. See PEP 309.
1795
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001796- Patch #1493701: performance enhancements for struct module.
1797
Georg Brandl378d5922006-05-17 14:26:50 +00001798- Patch #1490224: time.altzone is now set correctly on Cygwin.
1799
Georg Brandl8d3342b2006-05-16 07:38:27 +00001800- Patch #1435422: zlib's compress and decompress objects now have a
1801 copy() method.
1802
Andrew MacIntyre92913322006-06-13 15:04:24 +00001803- Patch #1454481: thread stack size is now tunable at runtime for thread
1804 enabled builds on Windows and systems with Posix threads support.
1805
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001806- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1807 (up to the system limit of 32K characters).
1808
1809- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1810 As a result, these functions now raise WindowsError instead of OSError.
1811
Tim Peters7a822da2006-05-25 21:50:17 +00001812- ``time.clock()`` on Win64 should use the high-performance Windows
1813 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1814 Windows platforms).
1815
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001816- Calling Tk_Init twice is refused if the first call failed as that
1817 may deadlock.
1818
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001819- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1820 accept it without potentially using an uninitialized pointer.
1821
1822- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1823 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1824 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001825
Gregory P. Smith372b5832006-06-05 18:48:21 +00001826- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001827 [pybsddb project SF patch number 1466734]
1828
Gregory P. Smith372b5832006-06-05 18:48:21 +00001829- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1830 parameter is supplied. [SF pybsddb bug #1477863]
1831
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001832- bsddb: the __len__ method of a DB object has been fixed to return correct
1833 results. It could previously incorrectly return 0 in some cases.
1834 Fixes SF bug 1493322 (pybsddb bug 1184012).
1835
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001836- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1837 aborts the db transaction safely when a modifier callback fails.
1838 Fixes SF python patch/bug #1408584.
1839
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001840- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001841 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001842 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1843 database calls that would previously deadlock. [SF python bug #775414]
1844
Vinay Sajip28e57612006-07-01 10:45:20 +00001845- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001846
Walter Dörwald4994d952006-06-19 08:07:50 +00001847- Patch #1506645: add Python wrappers for the curses functions
1848 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001849

1852
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001853- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1854 functions.
1855
Martin v. Löwis3798da02006-06-17 18:44:27 +00001856- Patch #812986: Update turtle output even if not tracing.
1857
Vinay Sajip28e57612006-07-01 10:45:20 +00001858- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001859 Tkinter.BaseWidget.
1860
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001861- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1862
Martin v. Löwis337487e2006-06-17 09:15:14 +00001863- Patch #763580: Add name and value arguments to Tkinter variable
1864 classes.
1865
Georg Brandl83cc0d02006-06-14 08:50:03 +00001866- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1867 mime.types file for determining MIME types.
1868
Georg Brandl2605ca82006-06-14 06:08:31 +00001869- Bug #1339007: Shelf objects now don't raise an exception in their
1870 __del__ method when initialization failed.
1871
Martin v. Löwisd8251432006-06-14 05:21:04 +00001872- Patch #1455898: The MBCS codec now supports the incremental mode for
1873 double-byte encodings.
1874
Tim Peters43898b42006-06-14 04:09:25 +00001875- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1876 guarantee that adjacent triples in the return list always describe
1877 non-adjacent blocks. Previously, a pair of matching blocks could end
1878 up being described by multiple adjacent triples that formed a partition
1879 of the matching pair.
1880
Greg Ward0e0c9f42006-06-11 16:24:11 +00001881- Bug #1498146: fix optparse to handle Unicode strings in option help,
1882 description, and epilog.
1883
Greg Wardd1c797e2006-06-11 14:42:41 +00001884- Bug #1366250: minor optparse documentation error.
1885
Greg Ward7f547402006-06-11 00:40:49 +00001886- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1887 clarify docs.
1888
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001889- The wsgiref package has been added to the standard library.
1890
Nick Coghlan676725d2006-06-08 13:54:49 +00001891- The functions update_wrapper() and wraps() have been added to the functools
1892 module. These make it easier to copy relevant metadata from the original
1893 function when writing wrapper functions.
1894
Tim Petersd6a9eef2006-06-05 01:48:21 +00001895- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1896 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001897
Martin v. Löwis3f767792006-06-04 19:36:28 +00001898- Patch #1359618: Speed up charmap encoder by using a trie structure
1899 for lookup.
1900
Tim Petersd609b1a2006-06-02 23:22:51 +00001901- The functions in the ``pprint`` module now sort dictionaries by key
1902 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1903 if and only if its display required more than one line, although that
1904 wasn't documented. The new behavior increases predictability; e.g.,
1905 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1906
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001907- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1908 (thanks for J. J. Lee).
1909
Georg Brandl2b330372006-05-28 20:23:12 +00001910- Patch #1496206: improve urllib2 handling of passwords with respect to
1911 default HTTP and HTTPS ports.
1912
George Yoshidaf3c65de2006-05-28 16:39:09 +00001913- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1914
Bob Ippolito7298f272006-05-23 18:43:47 +00001915- Patch #1281707: speed up gzip.readline.
1916
Georg Brandlb89316f2006-05-17 15:51:16 +00001917- Patch #1180296: Two new functions were added to the locale module:
1918 format_string() to get the effect of "format % items" but locale-aware,
1919 and currency() to format a monetary number with currency sign.
1920
Georg Brandle3a25832006-05-17 14:56:04 +00001921- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1922 and several features added, such as speed and geometry control.
1923
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001924- Patch #1488881: add support for external file objects in bz2 compressed
1925 tarfiles.
1926
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001927- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1928 stdout arguments, making it possible to redirect input and output
1929 for remote debugging.
1930
1931- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1932 a couple of issues, notably handling of long file names using the
1933 GNU LONGNAME extension.
1934
1935- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1936 new flag when ``name`` is already the name of an option flag.
1937
1938- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1939 package.
1940
1941- Patch #1472854: make the rlcompleter.Completer class usable on non-
1942 UNIX platforms.
1943
1944- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1945
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001946- Bug #1472827: correctly escape newlines and tabs in attribute values in
1947 the saxutils.XMLGenerator class.

1982Core and builtins
1983-----------------
1984
Thomas Heller1b046642006-04-18 18:51:06 +00001985- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1986 by converting these apis from macros into exported functions again:
1987
1988 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1989 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1990 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1991 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1992 PyRun_String Py_CompileString
1993
Martin v. Löwis45294a92006-04-18 06:24:08 +00001994- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1995
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001996- All uses of PyStructSequence_InitType have been changed to initialize
1997 the type objects only once, even if the interpreter is initialized
1998 multiple times.
1999
Neal Norwitz61546162006-04-14 05:20:28 +00002000- Bug #1454485, array.array('u') could crash the interpreter. This was
2001 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2002 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2003
2004- Py_UNICODE is unsigned. It was always documented as unsigned, but
2005 due to a bug had a signed value in previous versions.
2006
Tim Peters3a5e8b12006-04-11 01:44:07 +00002007- Patch #837242: ``id()`` of any Python object always gives a positive
2008 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2009 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002010 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002011 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002012
Tim Peters3a5e8b12006-04-11 01:44:07 +00002013 def __hash__(self):
2014 return id(self) # WRONG
2015
2016 because a hash result must be a (short) Python int but it was always
2017 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002018 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002019 was always usable as a hash value before this patch. That's no longer
2020 necessarily so.
2021
2022- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002023 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002024 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002025 #1454844)
2026
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002027- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2028 involving generators that have paused outside of any ``try`` or ``with``
2029 blocks. (In 2.5a1, a paused generator that was part of a reference
2030 cycle could not be garbage collected, regardless of whether it was
2031 paused in a ``try`` or ``with`` block.)

2034-----------------
2035
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00002036- Patch #1191065: Fix preprocessor problems on systems where recvfrom
2037 is a macro.
2038
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002039- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2040 fails with an error condition.
2041
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002042- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2043
2044- Bug #1117761: bsddb.*open() no longer raises an exception when using
2045 the cachesize parameter.
2046
2047- Bug #1149413: bsddb.*open() no longer raises an exception when using
2048 a temporary db (file=None) with the 'n' flag to truncate on open.

Peter Astrand7d1d4362006-07-14 14:04:45 +00002059- Bug #1223937: subprocess.CalledProcessError reports the exit status
2060 of the process using the returncode attribute, instead of
2061 abusing errno.
2062
Tim Peters711bf302006-04-25 03:31:36 +00002063- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2064 a doctest to be skipped (the code is not run, and the expected output
2065 or exception is ignored).
2066
Nick Coghlanda2268f2006-04-24 04:37:15 +00002067- Fixed contextlib.nested to cope with exceptions being raised and
2068 caught inside exit handlers.
2069
Greg Wardab05edc2006-04-23 03:47:58 +00002070- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2071 hex, octal, or binary; add ``append_const`` action; keep going if
2072 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2073 added ``epilog`` for better help generation).
2074
Tim Peters21fbd572006-04-21 21:18:10 +00002075- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2076 called from a thread spawned as a side effect of importing a module.
2077
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002078- The pydoc module now supports documenting packages contained in
2079 .zip or .egg files.
2080
2081- The pkgutil module now has several new utility functions, such
2082 as ``walk_packages()`` to support working with packages that are either
2083 in the filesystem or zip files.
2084
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002085- The mailbox module can now modify and delete messages from
2086 mailboxes, in addition to simply reading them. Thanks to Gregory
2087 K. Johnson for writing the code, and to the 2005 Google Summer of
2088 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002089
Tim Petersc7605f22006-04-17 21:12:33 +00002090- The ``__del__`` method of class ``local`` in module ``_threading_local``
2091 returned before accomplishing any of its intended cleanup.

Skip Montanaro262fb922006-04-21 02:31:07 +00002113- The pstats.Stats class accepts an optional stream keyword argument to
2114 direct output to an alternate file-like object.
2115
Anthony Baxter51bcb682006-04-05 14:51:42 +00002116Build
2117-----
2118
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002119- The Makefile now has a reindent target, which runs reindent.py on
2120 the library.
2121
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002122- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002125
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002126- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2127 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002128 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002129 CXX from --with-cxx-main, see description in README.
2130
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002131- Patch #1429775: Link extension modules with the shared libpython.
2132

2134
Tim Peters8931ff12006-05-13 23:28:20 +00002135- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2136 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2137 and "%zu" for unsigned integers of type ``size_t``.
2138
Anthony Baxter51bcb682006-04-05 14:51:42 +00002139Tests
2140-----
2141
Nick Coghlanda2268f2006-04-24 04:37:15 +00002142- test_contextlib now checks contextlib.nested can cope with exceptions
2143 being raised and caught inside exit handlers.
2144
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002145- test_cmd_line now checks operation of the -m and -c command switches
2146
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002147- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2148 it separately and by hand. It also wasn't cleaning up its changes to
2149 the current Decimal context.
2150
Thomas Woutersabd08882006-04-26 15:53:30 +00002151- regrtest.py now has a -M option to run tests that test the new limits of
2152 containers, on 64-bit architectures. Running these tests is only sensible
2153 on 64-bit machines with more than two gigabytes of memory. The argument
2154 passed is the maximum amount of memory for the tests to use.

2163-------------
2164
Tim Petersb06d28c2006-05-12 01:57:59 +00002165- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2166
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002167- PEP 343: Added Context Types section to the library reference
2168 and attempted to bring other PEP 343 related documentation into
2169 line with the implementation and/or python-dev discussions.
2170
Tim Peters8dc73d22006-04-24 02:03:16 +00002171- Bug #1337990: clarified that ``doctest`` does not support examples
2172 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002175What's New in Python 2.5 alpha 1?
2176=================================
2177
Anthony Baxterebed3f62006-04-03 15:03:44 +00002178*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002179
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002180Core and builtins
2181-----------------
2182
Nick Coghlan43832302006-04-23 17:04:07 +00002183- PEP 338: -m command line switch now delegates to runpy.run_module
2184 allowing it to support modules in packages and zipfiles
2185
Martin v. Löwisc661b882006-04-20 04:54:23 +00002186- On Windows, .DLL is not an accepted file name extension for
2187 extension modules anymore; extensions are only found if they
2188 end in .PYD.
2189
Martin v. Löwisea62d252006-04-03 10:56:49 +00002190- Bug #1421664: sys.stderr.encoding is now set to the same value as
2191 sys.stdout.encoding.
2192
Neal Norwitz92e212f2006-04-03 04:48:37 +00002193- __import__ accepts keyword arguments.
2194
Georg Brandlccadf842006-03-31 18:54:53 +00002195- Patch #1460496: round() now accepts keyword arguments.
2196
Anthony Baxter262c00a2006-03-30 10:53:17 +00002197- Fixed bug #1459029 - unicode reprs were double-escaped.
2198
Hye-Shik Changd478f342006-03-23 12:32:36 +00002199- Patch #1396919: The system scope threads are reenabled on FreeBSD
2200 5.4 and later versions.
2201
Neal Norwitze98ccf62006-03-23 05:39:47 +00002202- Bug #1115379: Compiling a Unicode string with an encoding declaration
2203 now gives a SyntaxError.
2204
Georg Brandlabd1ff82006-03-18 07:59:59 +00002205- Previously, Python code had no easy way to access the contents of a
2206 cell object. Now, a ``cell_contents`` attribute has been added
2207 (closes patch #1170323).
2208
Tim Peterscf79aac2006-03-16 01:14:46 +00002209- Patch #1123430: Python's small-object allocator now returns an arena to
2210 the system ``free()`` when all memory within an arena becomes unused
2211 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2212 freed. Some applications will see a drop in virtual memory size now,
2213 especially long-running applications that, from time to time, temporarily
2214 use a large number of small objects. Note that when Python returns an
2215 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002216 platform C library will in turn return that memory to the operating system.
2217 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002218 appears to be effective at least on Microsoft C and gcc-based systems.
2219 Thanks to Evan Jones for hard work and patience.
2220
Georg Brandl533ff6f2006-03-08 18:09:27 +00002221- Patch #1434038: property() now uses the getter's docstring if there is
2222 no "doc" argument given. This makes it possible to legitimately use
2223 property() as a decorator to produce a read-only property.
2224
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002225- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2226 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2227 of requiring an int or long in slicing and a few other contexts, enabling
2228 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2229
Neal Norwitz995acdf2006-03-07 05:01:00 +00002230- Fixed various bugs reported by Coverity's Prevent tool.
2231
Brett Cannonbf364092006-03-01 04:25:17 +00002232- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2233 new exception base class, BaseException, which has a new message attribute.
2234 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2235 Raising a string exception now raises a DeprecationWarning.
2236
Thomas Woutersfb609f42006-02-28 16:37:25 +00002237- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2238 explicitly relative, using 'from .module import name' to mean 'from the same
2239 package as this module is in. Imports without dots still default to the
2240 old relative-then-absolute, unless 'from __future__ import
2241 absolute_import' is used.
2242
Brett Cannona7446e32006-02-27 23:39:10 +00002243- Properly check if 'warnings' raises an exception (usually when a filter set
2244 to "error" is triggered) when raising a warning for raising string
2245 exceptions.
2246
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002247- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002248 The name was removed from Include/code.h.
2249
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002250- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002251
Guido van Rossum1968ad32006-02-25 22:38:04 +00002252- Patch 1433928:
2253 - The copy module now "copies" function objects (as atomic objects).
2254 - dict.__getitem__ now looks for a __missing__ hook before raising
2255 KeyError.
2256
Tim Peters84ef21c2006-02-28 20:39:06 +00002257- PEP 343: with statement implemented. Needs ``from __future__ import
2258 with_statement``. Use of 'with' as a variable will generate a warning.
2259 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002260 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002261 The following objects have __context__ methods:
2262 - The built-in file type.
2263 - The thread.LockType type.
2264 - The following types defined by the threading module:
2265 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2266 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002267
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002268- Fix the encodings package codec search function to only search
2269 inside its own package. Fixes problem reported in patch #1433198.
2270
2271 Note: Codec packages should implement and register their own
2272 codec search function. PEP 100 has the details.
2273
Tim Peters9ea89d22006-06-04 03:26:02 +00002274- PEP 353: Using ``Py_ssize_t`` as the index type.
2275
2276- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2277 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2278 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2279 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2280 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002281
Neal Norwitzfc76d632006-01-10 06:03:13 +00002282- Patch #1400181, fix unicode string formatting to not use the locale.
2283 This is how string objects work. u'%f' could use , instead of .
2284 for the decimal point. Now both strings and unicode always use periods.
2285
Neal Norwitz671b9e32006-01-09 07:07:12 +00002286- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2287 configure would break checking curses.h.
2288
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002289- Bug #959576: The pwd module is now builtin. This allows Python to be
2290 built on UNIX platforms without $HOME set.
2291
Neal Norwitzc10978f2005-12-19 06:07:16 +00002292- Bug #1072182, fix some potential problems if characters are signed.
2293
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002294- Bug #889500, fix line number on SyntaxWarning for global declarations.
2295
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002296- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2297
Neal Norwitze7214a12005-12-18 05:03:17 +00002298- Support for converting hex strings to floats no longer works.
2299 This was not portable. float('0x3') now raises a ValueError.
2300
Barry Warsaw2a38a862005-12-18 01:27:35 +00002301- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002302 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002303 is now displayed in interactive prompt banner.
2304
Georg Brandlfa166682005-12-17 21:45:17 +00002305- Implementation of PEP 341 - Unification of try/except and try/finally.
2306 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002307 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002308
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002309- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2310 now encodes backslash correctly.
2311
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002312- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2313
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002314- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002315 and long longs.
2316
Neal Norwitz67715f02005-11-09 06:59:35 +00002317- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002318 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002319 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002320
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002321- Replaced most Unicode charmap codecs with new ones using the
2322 new Unicode translate string feature in the builtin charmap
2323 codec; the codecs were created from the mapping tables available
2324 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2325 encodings now include a mapping for the Apple logo)
2326
Tim Peterse3547fd2005-12-16 23:13:57 +00002327- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002328
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002329- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002330
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002331- A new AST parser implementation was completed. The abstract
2332 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002333 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002334
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002335- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002336 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2337
Neal Norwitz708e51a2005-10-03 04:48:15 +00002338- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2339
Neal Norwitz11bd1192005-10-03 00:54:56 +00002340- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2341 Provide a warning when a directory is passed on the command line.
2342
Neal Norwitz40d37812005-10-02 01:48:49 +00002343- Fix segfault with invalid coding.
2344
2345- SF bug #772896: unknown encoding results in MemoryError.
2346
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002347- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002348 supported a __len__() method which evaluated to False when the iterator
2349 was empty.
2350
Guido van Rossum630db602005-09-20 18:49:54 +00002351- On 64-bit platforms, when __len__() returns a value that cannot be
2352 represented as a C int, raise OverflowError.
2353
Skip Montanarof8948ca2005-09-19 03:54:46 +00002354- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002355 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002356
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002357- SF bug #893549: parsing keyword arguments was broken with a few format
2358 codes.
2359
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002360- Changes donated by Elemental Security to make it work on AIX 5.3
2361 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2362 bug #105470: test_pwd fails on 64bit system (Opteron).
2363
Guido van Rossum539c6622005-09-14 17:49:54 +00002364- Changes donated by Elemental Security to make it work on HP-UX 11 on
2365 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2366
Georg Brandl4550b8d2005-08-26 06:43:52 +00002367- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002368 (fixes bug #1119418).
2369
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002370- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2371
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002372- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2373 exceptions that cause a function to exit.
2374
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002375- The implementation of set() and frozenset() was revised to use its
2376 own internal data structure. Memory consumption is reduced by 1/3
2377 and there are modest speed-ups as well. The API is unchanged.
2378
Tim Petersde7990b2005-07-17 23:45:23 +00002379- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2380
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002381- SF bug #1229429: PyObject_CallMethod failed to decrement some
2382 reference counts in some error exit cases.
2383
Tim Petersecc6e6a2005-07-10 22:30:55 +00002384- SF bug #1185883: Python's small-object memory allocator took over
2385 a block managed by the platform C library whenever a realloc specified
2386 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002387 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002388 portable way to copy data from the C-managed block into Python's
2389 small-object space without risking a memory fault. Python's small-object
2390 realloc now leaves such blocks under the control of the platform C
2391 realloc.
2392
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002393- SF bug #1232517: An overflow error was not detected properly when
2394 attempting to convert a large float to an int in os.utime().
2395
Raymond Hettinger3296e692005-06-29 23:29:56 +00002396- SF bug #1224347: hex longs now print with lowercase letters just
2397 like their int counterparts.
2398
Michael W. Hudson188d4362005-06-20 16:52:57 +00002399- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2400 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2401 interpreter states; back out that fix and do a better job (see
2402 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2403 for a longer write-up of the problem).
2404
Michael W. Hudsondf888462005-06-03 14:41:55 +00002405- SF patch #1180995: marshal now uses a binary format by default when
2406 serializing floats.
2407
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002408- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2409 the routines that promise to produce IEEE 754 binary representations
2410 of floats now simply copy bytes around.
2411
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002412- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2413 278.
2414
Brett Cannonc3647ac2005-04-26 03:45:26 +00002415- patch #1109424: int, long, float, complex, and unicode now check for the
2416 proper magic slot for type conversions when subclassed. Previously the
2417 magic slot was ignored during conversion. Semantics now match the way
2418 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002419 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002420 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002421 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002422
Barry Warsawc8d907c2005-04-19 23:43:40 +00002423- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2424 NULL, now raise an AttributeError when attempting to set or delete the
2425 attribute. Previously a TypeError was raised, but this was inconsistent
2426 with the equivalent pure-Python implementation.
2427
Michael W. Hudson774479c2005-04-18 08:46:17 +00002428- It is now safe to call PyGILState_Release() before
2429 PyEval_InitThreads() (note that if there is reason to believe there
2430 are multiple threads around you still must call PyEval_InitThreads()
2431 before using the Python API; this fix is for extension modules that
2432 have no way of knowing if Python is multi-threaded yet).
2433
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002434- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2435 disabled caused a crash.
2436
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002437- Bug #1165306: instancemethod_new allowed the creation of a method
2438 with im_class == im_self == NULL, which caused a crash when called.
2439
Tim Petersecc6e6a2005-07-10 22:30:55 +00002440- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002441 fixes the crash seen in bug #1165761
2442
Raymond Hettinger96229b12005-03-11 06:49:40 +00002443- Added two new builtins, any() and all().
2444
Brett Cannon409d8f22005-03-05 06:47:57 +00002445- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002446 (e.g., ``class C(): pass`` is no longer a syntax error).
2447 Patch #1176012 added support to the 'parser' module and 'compiler' package
2448 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002449
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002450- Patch #1115086: Support PY_LONGLONG in structmember.
2451
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002452- Bug #1155938: new style classes did not check that __init__() was
2453 returning None.
2454
Tim Petersecc6e6a2005-07-10 22:30:55 +00002455- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002456 ('\') with a specific error message.
2457
Martin v. Löwisff232d72005-03-03 09:24:38 +00002458- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2459
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002460- Bug #1124295: the __name__ attribute of file objects was
2461 inadvertently made inaccessible in restricted mode.
2462
Tim Petersecc6e6a2005-07-10 22:30:55 +00002463- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002464 an ferror() call.
2465
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002466- min() and max() now support key= arguments with the same meaning as in
2467 list.sort().
2468
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002469- The peephole optimizer now performs simple constant folding in expressions:
2470 (2+3) --> (5).
2471
Raymond Hettingera422c342005-01-11 03:03:27 +00002472- set and frozenset objects can now be marshalled. SF #1098985.
2473
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002474- Bug #1077106: Poor argument checking could cause memory corruption
2475 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002476
Jeremy Hyltonab630502005-02-04 18:44:06 +00002477- The parser did not complain about future statements in illegal
2478 positions. It once again reports a syntax error if a future
2479 statement occurs after anything other than a doc string.
2480
Neil Schemenauercf52c072005-08-12 17:34:58 +00002481- Change the %s format specifier for str objects so that it returns a
2482 unicode instance if the argument is not an instance of basestring and
2483 calling __str__ on the argument returns a unicode instance.
2484
Tim Petersf4e69282006-02-27 17:15:31 +00002485- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2486 current thread state when the auto-GIL-state machinery knows about
2487 it (since the thread state is being deleted, continuing to remember it
2488 can't help, but can hurt if another thread happens to get created with
2489 the same thread id).
2490
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002491Extension Modules
2492-----------------
2493

Neal Norwitz10be10c2006-03-16 06:50:13 +00002507 util, whatsound, whrandom, zmod
2508
2509- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2510
2511- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002512 is deprecated. The undocumented re.engine variable no longer exists.
2513
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002514- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2515 SS2 (single-shift 2) escape sequences correctly.
2516
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002517- The unicodedata module was updated to the 4.1 version of the Unicode
2518 database. The 3.2 version is still available as unicodedata.db_3_2_0
2519 for applications that require this specific version (such as IDNA).
2520
Neal Norwitzb62c4332006-03-04 18:35:47 +00002521- The timing module is no longer built by default. It was deprecated
2522 in PEP 4 in Python 2.0 or earlier.
2523
Guido van Rossum1968ad32006-02-25 22:38:04 +00002524- Patch 1433928: Added a new type, defaultdict, to the collections module.
2525 This uses the new __missing__ hook behavior added to dict (see above).
2526
Georg Brandldbd83392006-02-20 09:42:33 +00002527- Bug #854823: socketmodule now builds on Sun platforms even when
2528 INET_ADDRSTRLEN is not defined.
2529
Georg Brandlf4f44152006-02-18 22:29:33 +00002530- Patch #1393157: os.startfile() now has an optional argument to specify
2531 a "command verb" to invoke on the file.
2532
Neal Norwitz082b2df2006-02-07 07:04:46 +00002533- Bug #876637, prevent stack corruption when socket descriptor
2534 is larger than FD_SETSIZE.
2535
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002536- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2537 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2538 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

2541 than the system default domain.
2542
Martin v. Löwis14694662006-02-03 12:54:16 +00002543- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2544 are reported, the limit on path name lengths is removed, and stat reports
2545 WindowsError now (instead of OSError).
2546
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002547- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

Michael W. Hudson8137bea2005-07-27 20:24:40 +00002621- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
2622 the request code argument, which results in more C-like behaviour
2623 for large or negative values.
2624
Tim Petersecc6e6a2005-07-10 22:30:55 +00002625- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002665- the cPickle module no longer accepts the deprecated None option in the
2666 args tuple returned by __reduce__().
2667
Raymond Hettingerb2594052004-12-05 09:25:51 +00002668- itertools.islice() now accepts None for the start and step arguments.
2669 This allows islice() to work more readily with slices:
2670 islice(s.start, s.stop, s.step)
2671
Skip Montanaro0af3ade2005-01-13 04:12:31 +00002672- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002681- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2682 been renamed to have only a single underscore prefix. This was done to
2683 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002684
Nick Coghlan43832302006-04-23 17:04:07 +00002685- PEP 338: new module runpy defines a run_module function to support
2686 executing modules which provide access to source code or a code object
2687 via the PEP 302 import mechanisms.
2688
Anthony Baxter93f5b932006-04-03 08:05:07 +00002689- The email module's parsedate_tz function now sets the daylight savings
2690 flag to -1 (unknown) since it can't tell from the date whether it should

2697 in attribute values.
2698
Anthony Baxterc51ee692006-04-01 00:57:31 +00002699- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002700 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002701 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002702 module will not be built.
2703
Tim Petersc17976e2006-04-01 00:26:53 +00002704- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2705 aren't officially supported here, and trying to use them will probably
2706 raise an exception some day. But dicts have been allowed, and "mostly
2707 worked", so support for them won't go away without warning.
2708
Georg Brandl338ef7d2006-03-31 18:42:16 +00002709- Bug #1445068: getpass.getpass() can now be given an explicit stream
2710 argument to specify where to write the prompt.
2711
Georg Brandl22ec80b2006-03-31 18:25:44 +00002712- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2719
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002720- Queue.Queue objects now support .task_done() and .join() methods
2721 to make it easier to monitor when daemon threads have completed
2722 processing all enqueued tasks. Patch #1455676.
2723

2727
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002728- email 4.0 package now integrated. This is largely the same as the email 3.0
2729 package that was included in Python 2.3, except that PEP 8 module names are
2730 now used (e.g. mail.message instead of email.Message). The MIME classes
2731 have been moved to a subpackage (e.g. email.mime.text instead of
2732 email.MIMEText). The old names are still supported for now. Several
2733 deprecated Message methods have been removed and lots of bugs have been
2734 fixed. More details can be found in the email package documentation.
2735
Walter Dörwald40108c92006-03-27 08:15:44 +00002736- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2737 (a subclass of tuple) that provides incremental decoders and encoders
2738 (a way to use stateful codecs without the stream API). Python functions
2739 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2740 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2741 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002742
Walter Dörwald067db482006-03-15 22:17:27 +00002743- Patch #1359365: Calling next() on a closed StringIO.String object raises
2744 a ValueError instead of a StopIteration now (like file and cString.String do).
2745 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2746 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002747
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002748- A regrtest option -w was added to re-run failed tests in verbose mode.

Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002759- PEP 343: new module contextlib.py defines decorator @contextmanager
2760 and helpful context managers nested() and closing().
2761

Martin v. Löwis3e865952006-01-24 15:51:21 +00002796 specifications, raises IOErrors when proxies for unsupported protocols
2797 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002820 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2821 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2822 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2823 Ronald L. Rivest offered this advice for Python:
2824
2825 "The consensus of researchers in this area (at least as
2826 expressed at the NIST Hash Function Workshop 10/31/05),
2827 is that SHA-256 is a good choice for the time being, but
2828 that research should continue, and other alternatives may
2829 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002830
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002831- Added a subset of Fredrik Lundh's ElementTree package. Available

2924 Bug #1224621.
2925
Raymond Hettinger68c04532005-06-10 11:05:19 +00002926- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002927 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002928 the generate_tokens() function now accepts a callable argument that
2929 terminates by raising StopIteration.
2930
Georg Brandl9166e1a2005-06-04 09:20:03 +00002931- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2939 class at all.
2940
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002941- distutils.commands.upload was added to support uploading distribution

2943
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002944- distutils.commands.register now encodes the data as UTF-8 before posting
2945 them to PyPI.
2946
Raymond Hettinger267b8682005-03-27 10:47:39 +00002947- decimal operator and comparison methods now return NotImplemented
2948 instead of raising a TypeError when interacting with other types. This
2949 allows other classes to implement __radd__ style methods and have them
2950 work as expected.
2951
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002952- Bug #1163325: Decimal infinities failed to hash. Attempting to
2953 hash a NaN raised an InvalidOperation instead of a TypeError.
2954
Tim Petersecc6e6a2005-07-10 22:30:55 +00002955- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2989
Guido van Rossumd0641422005-02-03 15:01:24 +00002990- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2991 disables recursive traversal through instance attributes, which can
2992 be exploited in various ways.
2993
Tim Peterse3547fd2005-12-16 23:13:57 +00002994- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002995 flags on the HTTP listening socket.
2996
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002997- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2998 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2999
Fred Drakefbdeaad2006-07-29 16:56:15 +00003000- Patches #893642, #1039083: add allow_none, encoding arguments to
3001 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003002
Martin v. Löwis1d11de62005-01-29 13:29:23 +00003003- Bug #1110478: Revert os.environ.update to do putenv again.
3004
Thomas Hellerd6c6e222005-01-20 19:20:16 +00003005- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3006
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003007- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3008
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003009- Enhancements to the csv module:
3010
3011 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003012 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003013 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003014 + Dialect parameter parsing has been re-implemented to improve error
3015 reporting.
3016 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3017 dictates.
3018 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003019 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003020 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003021 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3022 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003023 + reader now allows \r characters to be quoted (previously it only allowed
3024 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003025 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003026 + Dialect classes passed to the module are no longer instantiated by
3027 the module before being parsed (the former validation scheme required
3028 this, but the mechanism was unreliable).
3029 + The dialect registry now contains instances of the internal
3030 C-coded dialect type, rather than references to python objects.
3031 + the internal c-coded dialect type is now immutable.
3032 + register_dialect now accepts the same keyword dialect specifications
3033 as the reader and writer, allowing the user to register dialects
3034 without first creating a dialect class.
3035 + a configurable limit to the size of parsed fields has been added -
3036 previously, an unmatched quote character could result in the entire
3037 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003038 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003039 the parser field size limit (returning the former limit). The initial
3040 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003041 + A line_num attribute has been added to the reader object, which tracks
3042 the number of lines read from the source iterator. This is not
3043 the same as the number of records returned, as records can span
3044 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003045 + reader and writer objects were not being registered with the cyclic-GC.
3046 This has been fixed.
3047
Brett Cannone6539c42005-01-08 02:43:53 +00003048- _DummyThread objects in the threading module now delete self.__block that is
3049 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3050 lock primitives tend to be limited in number and thus should not be wasted on
3051 a _DummyThread object. Fixes bug #1089632.
3052
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003053- The imghdr module now detects Exif files.
3054
Raymond Hettinger6065d322004-12-20 23:51:53 +00003055- StringIO.truncate() now correctly adjusts the size attribute.
3056 (Bug #951915).
3057
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003058- locale.py now uses an updated locale alias table (built using
3059 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3060 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003061 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003062
Raymond Hettinger3557f422004-12-07 12:02:02 +00003063- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3064
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003065- the pickle module no longer accepts the deprecated None option in the
3066 args tuple returned by __reduce__().
3067
Brett Cannon84667c02004-12-07 03:25:18 +00003068- optparse now optionally imports gettext. This allows its use in setup.py.
3069
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003070- the pickle module no longer uses the deprecated bin parameter.
3071
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003072- the shelve module no longer uses the deprecated binary parameter.
3073
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003074- the pstats module no longer uses the deprecated ignore() method.
3075
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003076- the filecmp module no longer uses the deprecated use_statcache argument.
3077
Raymond Hettinger664347b2004-12-04 21:21:53 +00003078- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3079 extended or overridden by subclasses. Formerly, the subclassed method would
3080 be ignored by the rest of the module. (Bug #1078905).
3081
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003082- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003083 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003084
Walter Dörwald36733692004-12-22 12:50:50 +00003085- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3086 once when a size argument is given. This prevents a buffer overflow in the
3087 tokenizer with very long source lines.
3088
Barry Warsaw538561e2006-01-01 21:48:54 +00003089- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3090 immediately after creating the object, without any intervening
3091 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003092
Skip Montanaro05885812005-01-16 20:48:27 +00003093- The reconvert.quote function can now emit triple-quoted strings. The
3094 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003095
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003096- ``UserString.MutableString`` now supports negative indices in
3097 ``__setitem__`` and ``__delitem__``
3098
Greg Ward40407942005-03-05 02:53:17 +00003099- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3100 correctly.
3101
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003102- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3103 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3104 character even if the user has passed a size parameter to get a proper
3105 line ending. Remove the special handling of a "\r\n" that has been split
3106 between two lines.
3107
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003108- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3109 about illegal code points. The codec now supports PEP 293 style error
3110 handlers.
3111
Walter Dörwald78a78b02005-09-01 12:04:29 +00003112- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003113 from the input stream, so that the output is a byte string in the correct
3114 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003115
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003116- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3117 considering it exactly like a '*'.

Walter Dörwald007f8df2005-10-09 19:42:27 +00003119- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3120 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003121
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003122- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3123
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003124- Patch #1413711: Certain patterns of differences were making difflib
3125 touch the recursion limit.
3126
Walter Dörwald58917a62006-03-31 15:26:22 +00003127- Bug #947906: An object oriented interface has been added to the calendar
3128 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003129 called as a script (e.g. via ``python -mcalendar``). Localized month and
3130 weekday names can be ouput (even if an exotic encoding is used) using
3131 special classes that use unicode.

3140
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003141- Build support for Win64-AMD64 was added.
3142
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003143- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3144
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003145- Patch #881820: look for openpty and forkpty also in libbsd.
3146
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003147- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3148 The zlib module is now builtin on Windows.
3149
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003150- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3151
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003152- Bug #1189330: configure did not correctly determine the necessary
3153 value of LINKCC if python was built with GCC 4.0.
3154
Trent Mick8321b422005-07-26 02:29:21 +00003155- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3156 vulnerability in zlib 1.2.1 and 1.2.2.
3157
Brett Cannon08cd5982005-04-24 22:26:38 +00003158- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3159 flags that change binary compatibility. Changes were also made to
3160 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003161 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003162
Bob Ippolitoed233462005-03-29 13:47:59 +00003163- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3164 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3165 no longer exists). This configure patch makes things right.
3166
Martin v. Löwise2713be2005-03-08 15:03:08 +00003167- Bug #1158607: Build with --disable-unicode again.
3168
Brett Cannon46d96232005-02-16 00:07:19 +00003169- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3170 defined. Discovered as a result of not being able to build on OS X.
3171
Brett Cannon516592f2004-12-07 00:42:59 +00003172- setup.py now uses the directories specified in LDFLAGS using the -L option
3173 and in CPPFLAGS using the -I option for adding library and include
3174 directories, respectively, for compiling extension modules against. This has
3175 led to the core being compiled using the values in CPPFLAGS. It also removes
3176 the need for the special-casing of both DarwinPorts and Fink for darwin since
3177 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3178 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3179 Fink, ``-I/opt/local/include`` for DarwinPorts).
3180
Brett Cannon43802422005-02-10 20:48:03 +00003181- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3182 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3183 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3184 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003186C API
3187-----
3188
Tim Petersc9d78aa2006-03-26 23:27:58 +00003189- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3190 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3191 is obtained via the ``PyObject_`` family, it must be released via the
3192 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3193 always been officially true, but when Python's small-object allocator was
3194 introduced, an attempt was made to cater to a few extension modules
3195 discovered at the time that obtained memory via ``PyObject_New`` but
3196 released it via ``PyMem_DEL``. It's years later, and if such code still
3197 exists it will fail now (probably with segfaults, but calling wrong
3198 low-level memory management functions can yield many symptoms).
3199
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003200- Added a C API for set and frozenset objects.
3201
Raymond Hettinger66517482004-12-03 11:45:13 +00003202- Removed PyRange_New().
3203
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003204- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3205 mapping argument now. This string is used as a mapping table. Byte values
3206 greater than the length of the string and 0xFFFE are treated as undefined
3207 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00003213- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003214
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003215- Patch #1276356: New resource "urlfetch" is implemented. This enables
3216 even impatient people to run tests that require remote files.
