13-----------------
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000014
Georg Brandl45c33ce2008-08-11 09:13:26 +000015- Issue #3537: Fix an assertion failure when an empty but presized dict
16 object was stored in the freelist.
17
Neal Norwitz4f3be8a2008-07-31 17:08:14 +000018- Apply security patches from Apple.
19
Neal Norwitz83ac0142008-07-28 05:06:20 +000020- Issue #2620: Overflow checking when allocating or reallocating memory
21 was not always being done properly in some python types and extension
22 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
23 all been updated to perform better checks and places in the code that
24 would previously leak memory on the error path when such an allocation
25 failed have been fixed.
26
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +000027- Issue #2242: Fix a crash when decoding invalid utf-7 input on certain
28 Windows / Visual Studio versions.
29
Mark Dickinsonab396e02008-07-16 11:04:17 +000030- Issue #3360: Fix incorrect parsing of '020000000000.0', which
31 produced a ValueError instead of giving the correct float.
32
Amaury Forgeot d'Arcceda6a62008-07-01 20:52:56 +000033- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
34 set to a custom object whose write() method happens to install
35 another file in sys.stdout.
36
Amaury Forgeot d'Arcb15bdf72008-07-01 20:59:49 +000037- Issue #3088: Corrected a race condition in classes derived from
38 threading.local: the first member set by a thread could be saved in
39 another thread's dictionary.
40
Amaury Forgeot d'Arc3255e132008-06-16 19:22:42 +000041- Issue #3100: Corrected a crash on deallocation of a subclassed weakref which
42 holds the last (strong) reference to its referent.
43
Guido van Rossumaa975432008-04-10 22:43:58 +000044- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
45 having a self-referential tuple, which is possible from C code. Nor did
46 object's tp_str consider that a type's tp_str could do something that could
47 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
48 respectively, fixed the issues. (Backport of r58288 from trunk.)
49
Georg Brandld9f1da02008-03-29 01:50:46 +000050- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
51 cannot be executed.
52
Amaury Forgeot d'Arc8432d862008-03-28 20:45:42 +000053- The compilation of a class nested in another class used to leak one
54 reference on the outer class name.
55
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000056- Issue #1477: With narrow Unicode builds, the unicode escape sequence
57 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
58 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
59 UTF-16 surrogates are generated in this case, like normal unicode literals
60 and the 'unicode-escape' codec.
61
Neal Norwitzb3635f92008-03-18 04:17:36 +000062- Issue #2321: use pymalloc for unicode object string data to reduce
63 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +000064
Sean Reifscheider4af861c2008-03-20 17:39:31 +000065- Issue #2238: Some syntax errors in *args and **kwargs expressions could give
66 bogus error messages.
67
Gregory P. Smith14acde32008-04-09 23:41:13 +000068- Issue #2587: In the C API, PyString_FromStringAndSize() takes a signed size
69 parameter but was not verifying that it was greater than zero. Values
70 less than zero will now raise a SystemError and return NULL to indicate a
71 bug in the calling C code.
72
Gregory P. Smith9aa040d2008-06-02 00:07:25 +000073- Issue #2588, #2589: Fix potential integer underflow and overflow
74 conditions in the PyOS_vsnprintf C API function.

79
Robert Schuppenies78813dc2008-08-10 11:19:25 +000080- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
81 menu entries were not deleted.
82
Martin v. Löwisc7af7f32008-08-02 07:21:06 +000083- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
84
Brett Cannonff931572008-07-13 01:20:19 +000085- Issue #3339: dummy_thread.acquire() could return None which is not a valid

94 handlers that derive the same default base class.
95
Amaury Forgeot d'Arc198e3532008-03-27 23:41:59 +000096- Issue #2495: tokenize.untokenize now inserts a space between two consecutive
97 string literals; previously, ["" ""] was rendered as [""""], which is
98 incorrect python code.
99
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +0000100- Issue #2482: Make sure that the coefficient of a Decimal is always
101 stored as a str instance, not as a unicode instance. This ensures
102 that str(Decimal) is always an instance of str. This fixes a
103 regression from Python 2.5.1 to Python 2.5.2.
104
Mark Dickinson26c25d92008-03-25 14:35:25 +0000105- Issue #2478: fix failure of decimal.Decimal(0).sqrt()

Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000122 calling .read() on a socket object wrapped with makefile().
Andrew M. Kuchling664553a2008-02-23 19:30:59 +0000123
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +0000124- Bug #1433694: minidom's .normalize() failed to set .nextSibling for

128 stdout and stderr fds rather than leaving them open until the
129 instance is destroyed.
130
Gregory P. Smithf8f30fa2008-07-06 04:04:07 +0000131- Issue #2632: Prevent socket.read(bignumber) from over allocating memory
132 in the common case when the data is returned from the underlying socket
133 in increments much smaller than bignumber.
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +0000134
Gregory P. Smithb4bc9b92008-08-04 00:15:54 +0000135- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
136 argument in python 2.5, this broke code that subclassed Popen to include its
137 own poll method. Fixed my moving _deadstate to an _internal_poll method.
138

207
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000208- Issue #1920: "while 0" statements were completely removed by the compiler,
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000209 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000210 the condition is false. Now the compiler correctly emits bytecode for the
211 "else" suite.
212

Anthony Baxterb4096662006-08-16 03:42:26 +00001166*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001167
1168Core and builtins
1169-----------------
1170
Neal Norwitz24b6f202006-09-05 04:43:56 +00001171- Fix infinite recursion when subclassing long and overriding __hash__.
1172
1173- Fix concatenation (+=) of long strings.
1174
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001175- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001176 compared equal or unequal to a string and a UnicodeDecodeError
1177 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001178
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001179 Instead, the equal (==) and unequal (!=) comparison operators will
1180 now issue a UnicodeWarning and interpret the two objects as
1181 unequal. The UnicodeWarning can be filtered as desired using
1182 the warning framework, e.g. silenced completely, turned into an
1183 exception, logged, etc.
1184
1185 Note that compare operators other than equal and unequal will still
1186 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001187
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001188- Fix segfault when doing string formatting on subclasses of long.
1189
1190- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1191 with new-style classes.
1192
1193- Fix bug related to __len__ functions returning negative values with
1194 classic classes.
1195
1196- Patch #1538606, Fix __index__() clipping. There were some problems
1197 discovered with the API and how integers that didn't fit into Py_ssize_t
1198 were handled. This patch attempts to provide enough alternatives
1199 to effectively use __index__.
1200
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001201- Bug #1536021: __hash__ may now return long int; the final hash
1202 value is obtained by invoking hash on the long int.
1203
Thomas Hellerab1049c2006-08-08 17:37:00 +00001204- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1205
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001206- Bug #1535165: fixed a segfault in input() and raw_input() when
1207 sys.stdin is closed.
1208
Thomas Heller74d36f02006-08-04 18:17:40 +00001209- On Windows, the PyErr_Warn function is now exported from
1210 the Python dll again.
1211
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001212- Bug #1191458: tracing over for loops now produces a line event
1213 on each iteration. Fixing this problem required changing the .pyc
1214 magic number. This means that .pyc files generated before 2.5c1
1215 will be regenerated.
1216
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001217- Bug #1333982: string/number constants were inappropriately stored
1218 in the byte code and co_consts even if they were not used, ie
1219 immediately popped off the stack.
1220
Georg Brandle9462c72006-08-04 18:03:37 +00001221- Fixed a reference-counting problem in property().
1222
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001223
1224Library
1225-------
1226
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001227- Fix a bug in the ``compiler`` package that caused invalid code to be
1228 generated for generator expressions.
1229
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001230- The distutils version has been changed to 2.5.0. The change to
1231 keep it programmatically in sync with the Python version running
1232 the code (introduced in 2.5b3) has been reverted. It will continue
1233 to be maintained manually as static string literal.
1234
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001235- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001236 and this cannot be converted to the required C type, an exception is
1237 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001238 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001239
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001240- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001241 an exception.
1242
Tim Peterscbdd3502006-09-05 01:47:53 +00001243- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001244 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001245 workarounds for clocks with low resolution, to stop the code yielding
1246 duplicate UUIDs.
1247
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001248- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1249 before raising SystemExit, allowing IDLE to honor quit() and exit().
1250
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001251- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1252
Georg Brandl7a1af772006-08-14 21:55:28 +00001253- Patch #1536071: trace.py should now find the full module name of a
1254 file correctly even on Windows.
1255
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001256- logging's atexit hook now runs even if the rest of the module has
1257 already been cleaned up.
1258
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001259- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001260
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001261- Bug #1531405, format_exception no longer raises an exception if
1262 str(exception) raised an exception.
1263
Neil Schemenauer06ded092006-08-04 16:20:30 +00001264- Fix a bug in the ``compiler`` package that caused invalid code to be
1265 generated for nested functions.
1266
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001267
1268Extension Modules

1274
Georg Brandl3335a7a2006-08-14 21:42:55 +00001275- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1276 raises the correct exceptions.
1277
Thomas Heller1ce433e2006-08-14 16:20:04 +00001278- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1279 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1280
Thomas Heller86720042006-08-14 11:17:48 +00001281- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1282 uses the _as_parameter_ attribute when objects are passed to foreign
1283 function calls. The ctypes version number was changed to 1.0.1.
1284
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001285- Bug #1530559, struct.pack raises TypeError where it used to convert.
1286 Passing float arguments to struct.pack when integers are expected
1287 now triggers a DeprecationWarning.
1288
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001289

1299
Andrew MacIntyre16ee33a2006-08-06 12:37:03 +00001300- test_threading now skips testing alternate thread stack sizes on
1301 platforms that don't support changing thread stack size.
1302
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001303
Georg Brandl212b5872006-08-05 06:10:54 +00001304Documentation

1311-----
1312
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001313- Bug #1535502, build _hashlib on Windows, and use masm assembler
1314 code in OpenSSL.
1315
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001316- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001318- Bug #1530448, ctypes build failure on Solaris 10 was fixed.
Thomas Heller17984892006-08-04 18:57:34 +00001319
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001320
Tim Peters4643c2f2006-08-10 22:45:34 +00001321C API
1322-----

1325
Tim Peters4643c2f2006-08-10 22:45:34 +00001326- Bug #1069160. Internal correctness changes were made to
1327 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1328 the documentation was changed to state that the return value

Fred Drake53912162006-07-29 13:22:49 +00001332What's New in Python 2.5 beta 3?
1333================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001334
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001335*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001336
1337Core and builtins
1338-----------------
1339
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001340- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001341 returned a long (see PEP 353).
1342
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001343- Bug #1515471: string.replace() accepts character buffers again.
1344
Neal Norwitz07aadb12006-07-30 06:55:48 +00001345- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1346 This provides the proper warning for struct.pack().
1347 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1348
Neal Norwitz0d62a062006-07-30 06:53:31 +00001349- Patch #1531113: Fix augmented assignment with yield expressions.
1350 Also fix a SystemError when trying to assign to yield expressions.
1351
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001352- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1353 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1354 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1355 excessive filesystem operations during imports.
1356
Tim Petersbc24eee2006-07-27 01:14:53 +00001357- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1358 operations on signed longs that are formally undefined by C.
1359 Unfortunately, at least one compiler now cares about that, so complicated
1360 the code to make that compiler happy again.
1361
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001362- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1363
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001364- Patch #1232023: Stop including current directory in search
1365 path on Windows.
1366
Neal Norwitze1fdb322006-07-21 05:32:28 +00001367- Fix some potential crashes found with failmalloc.
1368
Neal Norwitze7563102006-07-17 01:00:16 +00001369- Fix warnings reported by Klocwork's static analysis tool.
1370
Neal Norwitz84be93b2006-07-16 01:50:38 +00001371- Bug #1512814, Fix incorrect lineno's when code within a function
1372 had more than 255 blank lines.
1373
Georg Brandl9dceedb2006-07-12 15:31:17 +00001374- Patch #1521179: Python now accepts the standard options ``--help`` and
1375 ``--version`` as well as ``/?`` on Windows.
1376
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001377- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001378 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001379 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001380
Tim Peters112aad32006-07-19 00:03:19 +00001381- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001382 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001383 new ``sys._current_frames()`` returns a dictionary with one entry,
1384 mapping the faux "thread id" 0 to the current frame.
1385
Ronald Oussoren3075e162006-07-25 20:28:55 +00001386- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001387
Ronald Oussoren3075e162006-07-25 20:28:55 +00001388
Neal Norwitza1f10902006-07-12 07:28:29 +00001389Library
1390-------
1391
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001392- Correction of patch #1455898: In the mbcs decoder, set final=False
1393 for stream decoder, but final=True for the decode function.
1394
Georg Brandl07fec3a2006-08-01 18:49:24 +00001395- os.urandom no longer masks unrelated exceptions like SystemExit or
1396 KeyboardInterrupt.
1397
Tim Peters4643c2f2006-08-10 22:45:34 +00001398- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001399 shutil.copytree on Windows
1400
Georg Brandle34ac7c2006-07-30 11:07:23 +00001401- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1402 refers to file descriptors, not file objects.
1403
Tim Peterscbdd3502006-09-05 01:47:53 +00001404- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001405 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001406 #1513611, and probably others.
1407
Georg Brandledd9b0d2006-07-29 09:33:26 +00001408- Bug #1441397: The compiler module now recognizes module and function
1409 docstrings correctly as it did in Python 2.4.
1410
Tim Peters6f681472006-07-27 23:44:37 +00001411- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1412 lost that tests are sorted by name before being run. This rarely
1413 matters for well-written tests, but can create baffling symptoms if
1414 side effects from one test to the next affect outcomes. ``DocTestFinder``
1415 has been changed to sort the list of tests it returns.
1416
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001417- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001418 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001419
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001420- Bug #978833: Really close underlying socket in _socketobject.close.
1421
Georg Brandldb232dc2006-08-20 13:15:43 +00001422- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1423 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001424
Georg Brandlcf0c1722006-07-26 07:23:32 +00001425- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1426 to recursive calls and call it with the failing package name.
1427
Martin v. Löwis0b483032006-07-25 09:53:12 +00001428- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1429
Georg Brandlc13c34c2006-07-24 14:09:56 +00001430- Patch #1515343: Fix printing of deprecated string exceptions with a
1431 value in the traceback module.
1432
Greg Ward48fae7a2006-07-23 16:05:51 +00001433- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1434
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001435- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1436
Brett Cannoncaebe222006-07-18 04:41:36 +00001437- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1438 argument tuple. For arguments where zero is illegal, the value is forced to
1439 the minimum value that is correct. This is to support an undocumented but
1440 common way people used to fill in inconsequential information in the time
1441 tuple pre-2.4.
1442
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001443- Patch #1220874: Update the binhex module for Mach-O.
1444
Barry Warsawb110bad2006-07-21 14:51:07 +00001445- The email package has improved RFC 2231 support, specifically for
1446 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1447 (name*0=<blah>) parameter continuations. This may change the types of
1448 values returned from email.message.Message.get_param() and friends.
1449 Specifically in some cases where non-encoded continuations were used,
1450 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1451 will just return the string (since non-encoded continuations don't have
1452 charset and language parts).
1453
1454 Also, whereas % values were decoded in all parameter continuations, they are
1455 now only decoded in encoded parameter parts.
1456
Ronald Oussoren3075e162006-07-25 20:28:55 +00001457- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1458
1459- Bug #1517996: IDLE now longer shows the default Tk menu when a
1460 path browser, class browser or debugger is the frontmost window on MacOS X
1461
Barry Warsaw00decd72006-07-27 23:43:15 +00001462- Patch #1520294: Support for getset and member descriptors in types.py,
1463 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1464 of an object against these built-in types and more importantly, for getting
1465 their docstrings printed in the interactive interpreter's help() function.

1469-----------------
1470
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001471- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1472 a socket operation on a socket with a timeout, the exception will be
1473 caught correctly. Previously, the exception was not caught.
1474
Thomas Heller1393d6a2006-07-28 21:43:20 +00001475- Patch #1529514: The _ctypes extension is now compiled on more
1476 openbsd target platforms.
1477
Tim Peters9cab5932006-07-28 00:30:00 +00001478- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1479 a memory leak, affecting pickles and deep copies.
1480
Tim Petersbc24eee2006-07-27 01:14:53 +00001481- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1485
Thomas Hellerce049a02006-07-14 17:51:14 +00001486- Patch #1521817: Index range checking on ctypes arrays containing
1487 exactly one element enabled again. This allows iterating over these
1488 arrays, without the need to check the array size before.
1489
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001490- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001491 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001492 /dev/null in certain cases; this is now fixed.
1493
Thomas Heller47d7a062006-07-12 08:43:47 +00001494- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1495 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001496
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001497- Because of a misspelled preprocessor symbol, ctypes was always
1498 compiled without thread support; this is now fixed.
1499
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001500- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1501 methods now allow their database parameter to be None as the
1502 sleepycat API allows.
1503
Matt Flemingec926502006-07-28 11:27:27 +00001504- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1505 bluetooth API compared with Linux and FreeBSD.
1506
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001507Tests
1508-----
1509
1510- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1511 how long the test file should take to play. Now accepts taking 2.93 secs
1512 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1513
Georg Brandl4793aa32006-07-28 18:31:39 +00001514- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1515 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1516 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +00001517
Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001518Build

1520
1521- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1522
Ronald Oussoren26cad082006-08-01 21:00:57 +00001523Mac
1524---
1525
1526- PythonLauncher now works correctly when the path to the script contains
1527 characters that are treated specially by the shell (such as quotes).
1528
1529- Bug #1527397: PythonLauncher now launches scripts with the working directory
1530 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001531 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001532 expect.

1541-----------------
1542
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001543- Bug #1441486: The literal representation of -(sys.maxint - 1)
1544 again evaluates to a int object, not a long.
1545
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001546- Bug #1501934: The scope of global variables that are locally assigned
1547 using augmented assignment is now correctly determined.
1548
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001549- Bug #927248: Recursive method-wrapper objects can now safely
1550 be released.
1551
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001552- Bug #1417699: Reject locale-specific decimal point in float()
1553 and atof().
1554
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001555- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1556 omit a default "error" argument for NULL pointer. This allows
1557 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001558
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001559- Bug #1519018: 'as' is now validated properly in import statements.
1560
Neal Norwitz28746ab2006-07-09 22:14:42 +00001561- On 64 bit systems, int literals that use less than 64 bits are
1562 now ints rather than longs.
1563
Neal Norwitzed657552006-07-10 00:04:44 +00001564- Bug #1512814, Fix incorrect lineno's when code at module scope
1565 started after line 256.
1566
Tim Peters32a83612006-07-10 21:08:24 +00001567- New function ``sys._current_frames()`` returns a dict mapping thread
1568 id to topmost thread stack frame. This is for expert use, and is
1569 especially useful for debugging application deadlocks. The functionality
1570 was previously available in Fazal Majid's ``threadframe`` extension
1571 module, but it wasn't possible to do this in a wholly threadsafe way from
1572 an extension.

1589
Thomas Woutersadd19112006-07-05 11:03:49 +00001590- string.Template() now correctly handles tuple-values. Previously,
1591 multi-value tuples would raise an exception and single-value tuples would
1592 be treated as the value they contain, instead.
1593
Martin v. Löwisede77f52006-07-03 13:01:35 +00001594- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1601 degrees and radians.
1602
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001603- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001604 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001605

1607 is created.
1608
Martin v. Löwis7596e832006-07-01 15:33:37 +00001609- Bug #1513223: .close() of a _socketobj now releases the underlying
1610 socket again, which then gets closed as it becomes unreferenced.

1613 attribute values.
1614
1615- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1616 sgmllib ('[' and ']' were not accepted).
1617
Georg Brandl1be63af2006-06-28 20:23:25 +00001618- Fix a bug in the turtle module's end_fill function.
1619
Brett Cannon53ab5b72006-06-22 16:49:14 +00001620- Bug #1510580: The 'warnings' module improperly required that a Warning
1621 category be either a types.ClassType and a subclass of Warning. The proper
1622 check is just that it is a subclass with Warning as the documentation states.
1623
Georg Brandlad29e632006-06-21 17:45:17 +00001624- The compiler module now correctly compiles the new try-except-finally
1625 statement (bug #1509132).
1626
Neal Norwitz60373cd2006-06-22 06:30:50 +00001627- The wsgiref package is now installed properly on Unix.
1628
Vinay Sajip28e57612006-07-01 10:45:20 +00001629- A bug was fixed in logging.config.fileConfig() which caused a crash on
1630 shutdown when fileConfig() was called multiple times.
1631
Gerhard Häring762fbd32006-07-02 17:48:30 +00001632- The sqlite3 module did cut off data from the SQLite database at the first
1633 null character before sending it to a custom converter. This has been fixed
1634 now.
1635
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001636Extension Modules
1637-----------------
1638
Tim Peters112aad32006-07-19 00:03:19 +00001639- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1640 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1641 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001642
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001643- Assigning None to pointer type fields in ctypes structures possible
1644 overwrote the wrong fields, this is fixed now.
1645
1646- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1647 on non-Windows platforms.
1648
1649- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1650 integer or long, without range checking.
1651
1652- Patch #1517790: It is now possible to use custom objects in the ctypes
1653 foreign function argtypes sequence as long as they provide a from_param
1654 method, no longer is it required that the object is a ctypes type.
1655
1656- The '_ctypes' extension module now works when Python is configured
1657 with the --without-threads option.
1658
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001659- Bug #1513646: os.access on Windows now correctly determines write
1660 access, again.
1661
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001662- Bug #1512695: cPickle.loads could crash if it was interrupted with
1663 a KeyboardInterrupt.

Neal Norwitza12aa882006-07-06 06:45:08 +00001665- Bug #1296433: parsing XML with a non-default encoding and
1666 a CharacterDataHandler could crash the interpreter in pyexpat.
1667
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001668- Patch #1516912: improve Modules support for OpenVMS.

1674
Tim Peters32a83612006-07-10 21:08:24 +00001675- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001676 Previously, the slight difference could cause compilation errors of the
1677 'zlib' module on systems with more than one version of zlib.
1678
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001679- The MSI compileall step was fixed to also support a TARGETDIR
1680 with spaces in it.

1698 documentation for the warnings module.
1699
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001700- Patch #1509163: MS Toolkit Compiler no longer available.

1711-----------------
1712
Georg Brandla56b9152006-06-19 06:35:54 +00001713- Patch #1507676: Error messages returned by invalid abstract object operations
1714 (such as iterating over an integer) have been improved and now include the
1715 type of the offending object to help with debugging.
1716
Brett Cannonea3912b2006-06-13 21:46:41 +00001717- Bug #992017: A classic class that defined a __coerce__() method that returned
1718 its arguments swapped would infinitely recurse and segfault the interpreter.
1719
Neal Norwitz909eb122006-06-12 02:13:21 +00001720- Fix the socket tests so they can be run concurrently.
1721
Neal Norwitzb9845e72006-06-12 02:11:18 +00001722- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001723 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001724
Brett Cannon22565aa2006-06-09 22:31:23 +00001725- Bug #532646: object.__call__() will continue looking for the __call__
1726 attribute on objects until one without one is found. This leads to recursion
1727 when you take a class and set its __call__ attribute to an instance of the
1728 class. Originally fixed for classic classes, but this fix is for new-style.
1729 Removes the infinite_rec_3 crasher.
1730
Georg Brandl24250812006-06-09 18:45:48 +00001731- The string and unicode methods startswith() and endswith() now accept
1732 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1733
Brett Cannonde3b0522006-06-08 17:00:45 +00001734- Buffer objects, at the C level, never used the char buffer
1735 implementation even when the char buffer for the wrapped object was
1736 explicitly requested (originally returned the read or write buffer).
1737 Now a TypeError is raised if the char buffer is not present but is
1738 requested.
1739
Georg Brandlddbaa662006-06-04 21:56:52 +00001740- Patch #1346214: Statements like "if 0: suite" are now again optimized
1741 away like they were in Python 2.4.
1742
Georg Brandlb7c8f542006-05-27 12:30:25 +00001743- Builtin exceptions are now full-blown new-style classes instead of
1744 instances pretending to be classes, which speeds up exception handling
1745 by about 80% in comparison to 2.5a2.
1746
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001747- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1748 Unicode 4.1.
1749
Georg Brandlf4ef1162006-05-26 18:03:31 +00001750- Patch #921466: sys.path_importer_cache is now used to cache valid and
1751 invalid file paths for the built-in import machinery which leads to
1752 fewer open calls on startup.
1753
Tim Peters696cf432006-05-24 21:10:40 +00001754- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1755 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1756 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1757 the number of input digits (it was and remains linear-time for bases
1758 2, 4, 8, 16 and 32).
1759
Tim Petersb713ec22006-05-23 18:45:30 +00001760- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1761 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1762 an integer close to ``sys.maxint``. This was repaired by patch
1763 #1335972, which also gives a nice speedup.
1764
Richard Jonescebbefc2006-05-23 18:28:17 +00001765- Patch #1337051: reduced size of frame objects.
1766
1767- PyErr_NewException now accepts a tuple of base classes as its
1768 "base" parameter.
1769
Richard Jones7c88dcc2006-05-23 10:37:38 +00001770- Patch #876206: function call speedup by retaining allocated frame
1771 objects.
1772
Georg Brandl7b90e162006-05-18 07:01:27 +00001773- Bug #1462152: file() now checks more thoroughly for invalid mode
1774 strings and removes a possible "U" before passing the mode to the
1775 C library function.
1776
Neal Norwitz1004a532006-05-15 07:17:23 +00001777- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1778
Neal Norwitz373f0a72006-05-15 07:04:36 +00001779- Bug #1487966: Fix SystemError with conditional expression in assignment
1780
Martin v. Löwis879768d2006-05-11 13:28:43 +00001781- WindowsError now has two error code attributes: errno, which carries
1782 the error values from errno.h, and winerror, which carries the error
1783 values from winerror.h. Previous versions put the winerror.h values
1784 (from GetLastError()) into the errno attribute.
1785
Martin v. Löwis77736712006-05-04 05:51:03 +00001786- Patch #1475845: Raise IndentationError for unexpected indent.
1787
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001788- Patch #1479181: split open() and file() from being aliases for each other.
1789
Tim Peters44bd9862006-06-01 13:49:23 +00001790- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1791 methods were always silently ignored by dictionaries when comparing keys.
1792 They are now passed through (except when using the C API function
1793 ``PyDict_GetItem()``, whose semantics did not change).
1794
1795- Bug #1456209: In some obscure cases it was possible for a class with a
1796 custom ``__eq__()`` method to confuse dict internals when class instances
1797 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1798 No, you don't have any code that did this ;-)

1801-----------------
1802
Trent Mick960a3f82006-06-28 20:30:41 +00001803- Bug #1295808: expat symbols should be namespaced in pyexpat
1804
1805- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1806
Brett Cannon6ee7d012006-06-08 16:23:04 +00001807- Change binascii.hexlify to accept a read-only buffer instead of only a char
1808 buffer and actually follow its documentation.
1809
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001810- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1811
Nick Coghlanc649ec52006-05-29 12:43:05 +00001812- Patch #1478788 (modified version): The functional extension module has
1813 been renamed to _functools and a functools Python wrapper module added.
1814 This provides a home for additional function related utilities that are
1815 not specifically about functional programming. See PEP 309.
1816
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001817- Patch #1493701: performance enhancements for struct module.
1818
Georg Brandl378d5922006-05-17 14:26:50 +00001819- Patch #1490224: time.altzone is now set correctly on Cygwin.
1820
Georg Brandl8d3342b2006-05-16 07:38:27 +00001821- Patch #1435422: zlib's compress and decompress objects now have a
1822 copy() method.
1823
Andrew MacIntyre92913322006-06-13 15:04:24 +00001824- Patch #1454481: thread stack size is now tunable at runtime for thread
1825 enabled builds on Windows and systems with Posix threads support.
1826
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001827- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1828 (up to the system limit of 32K characters).
1829
1830- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1831 As a result, these functions now raise WindowsError instead of OSError.
1832
Tim Peters7a822da2006-05-25 21:50:17 +00001833- ``time.clock()`` on Win64 should use the high-performance Windows
1834 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1835 Windows platforms).
1836
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001837- Calling Tk_Init twice is refused if the first call failed as that
1838 may deadlock.
1839
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001840- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1841 accept it without potentially using an uninitialized pointer.
1842
1843- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1844 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1845 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001846
Gregory P. Smith372b5832006-06-05 18:48:21 +00001847- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001848 [pybsddb project SF patch number 1466734]
1849
Gregory P. Smith372b5832006-06-05 18:48:21 +00001850- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1851 parameter is supplied. [SF pybsddb bug #1477863]
1852
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001853- bsddb: the __len__ method of a DB object has been fixed to return correct
1854 results. It could previously incorrectly return 0 in some cases.
1855 Fixes SF bug 1493322 (pybsddb bug 1184012).
1856
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001857- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1858 aborts the db transaction safely when a modifier callback fails.
1859 Fixes SF python patch/bug #1408584.
1860
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001861- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001862 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001863 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1864 database calls that would previously deadlock. [SF python bug #775414]
1865
Vinay Sajip28e57612006-07-01 10:45:20 +00001866- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001867
Walter Dörwald4994d952006-06-19 08:07:50 +00001868- Patch #1506645: add Python wrappers for the curses functions
1869 is_term_resized, resize_term and resizeterm.

1875 functions.
1876
Martin v. Löwis3798da02006-06-17 18:44:27 +00001877- Patch #812986: Update turtle output even if not tracing.

1881
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001882- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1883
Martin v. Löwis337487e2006-06-17 09:15:14 +00001884- Patch #763580: Add name and value arguments to Tkinter variable
1885 classes.
1886
Georg Brandl83cc0d02006-06-14 08:50:03 +00001887- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1888 mime.types file for determining MIME types.
1889
Georg Brandl2605ca82006-06-14 06:08:31 +00001890- Bug #1339007: Shelf objects now don't raise an exception in their
1891 __del__ method when initialization failed.
1892
Martin v. Löwisd8251432006-06-14 05:21:04 +00001893- Patch #1455898: The MBCS codec now supports the incremental mode for
1894 double-byte encodings.
1895
Tim Peters43898b42006-06-14 04:09:25 +00001896- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1897 guarantee that adjacent triples in the return list always describe
1898 non-adjacent blocks. Previously, a pair of matching blocks could end
1899 up being described by multiple adjacent triples that formed a partition
1900 of the matching pair.
1901
Greg Ward0e0c9f42006-06-11 16:24:11 +00001902- Bug #1498146: fix optparse to handle Unicode strings in option help,
1903 description, and epilog.
1904
Greg Wardd1c797e2006-06-11 14:42:41 +00001905- Bug #1366250: minor optparse documentation error.
1906
Greg Ward7f547402006-06-11 00:40:49 +00001907- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1908 clarify docs.
1909
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001910- The wsgiref package has been added to the standard library.
1911
Nick Coghlan676725d2006-06-08 13:54:49 +00001912- The functions update_wrapper() and wraps() have been added to the functools
1913 module. These make it easier to copy relevant metadata from the original
1914 function when writing wrapper functions.
1915
Tim Petersd6a9eef2006-06-05 01:48:21 +00001916- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1917 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001918
Martin v. Löwis3f767792006-06-04 19:36:28 +00001919- Patch #1359618: Speed up charmap encoder by using a trie structure
1920 for lookup.
1921
Tim Petersd609b1a2006-06-02 23:22:51 +00001922- The functions in the ``pprint`` module now sort dictionaries by key
1923 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1924 if and only if its display required more than one line, although that
1925 wasn't documented. The new behavior increases predictability; e.g.,
1926 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1927
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001928- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1929 (thanks for J. J. Lee).
1930
Georg Brandl2b330372006-05-28 20:23:12 +00001931- Patch #1496206: improve urllib2 handling of passwords with respect to
1932 default HTTP and HTTPS ports.
1933
George Yoshidaf3c65de2006-05-28 16:39:09 +00001934- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1935
Bob Ippolito7298f272006-05-23 18:43:47 +00001936- Patch #1281707: speed up gzip.readline.
1937
Georg Brandlb89316f2006-05-17 15:51:16 +00001938- Patch #1180296: Two new functions were added to the locale module:
1939 format_string() to get the effect of "format % items" but locale-aware,
1940 and currency() to format a monetary number with currency sign.
1941
Georg Brandle3a25832006-05-17 14:56:04 +00001942- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1943 and several features added, such as speed and geometry control.
1944
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001945- Patch #1488881: add support for external file objects in bz2 compressed
1946 tarfiles.
1947
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001948- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1949 stdout arguments, making it possible to redirect input and output
1950 for remote debugging.
1951
1952- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1953 a couple of issues, notably handling of long file names using the
1954 GNU LONGNAME extension.
1955
1956- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1957 new flag when ``name`` is already the name of an option flag.
1958
1959- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1960 package.
1961
1962- Patch #1472854: make the rlcompleter.Completer class usable on non-
1963 UNIX platforms.
1964
1965- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

2004-----------------
2005
Thomas Heller1b046642006-04-18 18:51:06 +00002006- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2007 by converting these apis from macros into exported functions again:
2008
2009 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2010 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2011 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

2013 PyRun_String Py_CompileString
2014
Martin v. Löwis45294a92006-04-18 06:24:08 +00002015- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2016
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002017- All uses of PyStructSequence_InitType have been changed to initialize
2018 the type objects only once, even if the interpreter is initialized
2019 multiple times.
2020
Neal Norwitz61546162006-04-14 05:20:28 +00002021- Bug #1454485, array.array('u') could crash the interpreter. This was
2022 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2023 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2024
2025- Py_UNICODE is unsigned. It was always documented as unsigned, but
2026 due to a bug had a signed value in previous versions.
2027
Tim Peters3a5e8b12006-04-11 01:44:07 +00002028- Patch #837242: ``id()`` of any Python object always gives a positive
2029 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2030 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002031 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002032 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002033
Tim Peters3a5e8b12006-04-11 01:44:07 +00002034 def __hash__(self):
2035 return id(self) # WRONG
2036
2037 because a hash result must be a (short) Python int but it was always
2038 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002039 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002040 was always usable as a hash value before this patch. That's no longer
2041 necessarily so.
2042
2043- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002044 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002045 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002046 #1454844)
2047
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002048- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2049 involving generators that have paused outside of any ``try`` or ``with``
2050 blocks. (In 2.5a1, a paused generator that was part of a reference
2051 cycle could not be garbage collected, regardless of whether it was
2052 paused in a ``try`` or ``with`` block.)

2081 of the process using the returncode attribute, instead of
2082 abusing errno.
2083
Tim Peters711bf302006-04-25 03:31:36 +00002084- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2085 a doctest to be skipped (the code is not run, and the expected output
2086 or exception is ignored).
2087
Nick Coghlanda2268f2006-04-24 04:37:15 +00002088- Fixed contextlib.nested to cope with exceptions being raised and
2089 caught inside exit handlers.

2092 hex, octal, or binary; add ``append_const`` action; keep going if
2093 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2094 added ``epilog`` for better help generation).
2095
Tim Peters21fbd572006-04-21 21:18:10 +00002096- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2097 called from a thread spawned as a side effect of importing a module.
2098
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002099- The pydoc module now supports documenting packages contained in
2100 .zip or .egg files.
2101
2102- The pkgutil module now has several new utility functions, such
2103 as ``walk_packages()`` to support working with packages that are either
2104 in the filesystem or zip files.
2105
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002106- The mailbox module can now modify and delete messages from
2107 mailboxes, in addition to simply reading them. Thanks to Gregory
2108 K. Johnson for writing the code, and to the 2005 Google Summer of
2109 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002110

Skip Montanaro262fb922006-04-21 02:31:07 +00002134- The pstats.Stats class accepts an optional stream keyword argument to
2135 direct output to an alternate file-like object.
2136
Anthony Baxter51bcb682006-04-05 14:51:42 +00002137Build
2138-----
2139
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002140- The Makefile now has a reindent target, which runs reindent.py on
2141 the library.
2142
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002143- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002146
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002147- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2148 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002149 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002150 CXX from --with-cxx-main, see description in README.
2151
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002152- Patch #1429775: Link extension modules with the shared libpython.
2153
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002154- Fixed a libffi build problem on MIPS systems.
2155
Tim Peters8931ff12006-05-13 23:28:20 +00002156- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2157 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2158 and "%zu" for unsigned integers of type ``size_t``.
2159
Anthony Baxter51bcb682006-04-05 14:51:42 +00002160Tests
2161-----
2162
Nick Coghlanda2268f2006-04-24 04:37:15 +00002163- test_contextlib now checks contextlib.nested can cope with exceptions
2164 being raised and caught inside exit handlers.
2165
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002166- test_cmd_line now checks operation of the -m and -c command switches
2167
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002168- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2169 it separately and by hand. It also wasn't cleaning up its changes to
2170 the current Decimal context.
2171
Thomas Woutersabd08882006-04-26 15:53:30 +00002172- regrtest.py now has a -M option to run tests that test the new limits of
2173 containers, on 64-bit architectures. Running these tests is only sensible
2174 on 64-bit machines with more than two gigabytes of memory. The argument
2175 passed is the maximum amount of memory for the tests to use.

Tim Petersb06d28c2006-05-12 01:57:59 +00002186- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2187
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002188- PEP 343: Added Context Types section to the library reference
2189 and attempted to bring other PEP 343 related documentation into
2190 line with the implementation and/or python-dev discussions.
2191
Tim Peters8dc73d22006-04-24 02:03:16 +00002192- Bug #1337990: clarified that ``doctest`` does not support examples
2193 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002196What's New in Python 2.5 alpha 1?
2197=================================
2198
Anthony Baxterebed3f62006-04-03 15:03:44 +00002199*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002200
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002201Core and builtins
2202-----------------
2203
Nick Coghlan43832302006-04-23 17:04:07 +00002204- PEP 338: -m command line switch now delegates to runpy.run_module
2205 allowing it to support modules in packages and zipfiles
2206
Martin v. Löwisc661b882006-04-20 04:54:23 +00002207- On Windows, .DLL is not an accepted file name extension for
2208 extension modules anymore; extensions are only found if they
2209 end in .PYD.
2210
Martin v. Löwisea62d252006-04-03 10:56:49 +00002211- Bug #1421664: sys.stderr.encoding is now set to the same value as
2212 sys.stdout.encoding.
2213
Neal Norwitz92e212f2006-04-03 04:48:37 +00002214- __import__ accepts keyword arguments.
2215
Georg Brandlccadf842006-03-31 18:54:53 +00002216- Patch #1460496: round() now accepts keyword arguments.
2217
Anthony Baxter262c00a2006-03-30 10:53:17 +00002218- Fixed bug #1459029 - unicode reprs were double-escaped.
2219
Hye-Shik Changd478f342006-03-23 12:32:36 +00002220- Patch #1396919: The system scope threads are reenabled on FreeBSD
2221 5.4 and later versions.
2222
Neal Norwitze98ccf62006-03-23 05:39:47 +00002223- Bug #1115379: Compiling a Unicode string with an encoding declaration
2224 now gives a SyntaxError.
2225
Georg Brandlabd1ff82006-03-18 07:59:59 +00002226- Previously, Python code had no easy way to access the contents of a
2227 cell object. Now, a ``cell_contents`` attribute has been added
2228 (closes patch #1170323).
2229
Tim Peterscf79aac2006-03-16 01:14:46 +00002230- Patch #1123430: Python's small-object allocator now returns an arena to
2231 the system ``free()`` when all memory within an arena becomes unused
2232 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2233 freed. Some applications will see a drop in virtual memory size now,
2234 especially long-running applications that, from time to time, temporarily
2235 use a large number of small objects. Note that when Python returns an
2236 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002237 platform C library will in turn return that memory to the operating system.
2238 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002239 appears to be effective at least on Microsoft C and gcc-based systems.
2240 Thanks to Evan Jones for hard work and patience.
2241
Georg Brandl533ff6f2006-03-08 18:09:27 +00002242- Patch #1434038: property() now uses the getter's docstring if there is
2243 no "doc" argument given. This makes it possible to legitimately use
2244 property() as a decorator to produce a read-only property.
2245
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002246- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2247 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2248 of requiring an int or long in slicing and a few other contexts, enabling
2249 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2250
Neal Norwitz995acdf2006-03-07 05:01:00 +00002251- Fixed various bugs reported by Coverity's Prevent tool.
2252
Brett Cannonbf364092006-03-01 04:25:17 +00002253- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2254 new exception base class, BaseException, which has a new message attribute.
2255 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2256 Raising a string exception now raises a DeprecationWarning.
2257
Thomas Woutersfb609f42006-02-28 16:37:25 +00002258- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2259 explicitly relative, using 'from .module import name' to mean 'from the same
2260 package as this module is in. Imports without dots still default to the
2261 old relative-then-absolute, unless 'from __future__ import
2262 absolute_import' is used.
2263
Brett Cannona7446e32006-02-27 23:39:10 +00002264- Properly check if 'warnings' raises an exception (usually when a filter set
2265 to "error" is triggered) when raising a warning for raising string
2266 exceptions.
2267
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002268- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002269 The name was removed from Include/code.h.
2270
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002271- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002272
Guido van Rossum1968ad32006-02-25 22:38:04 +00002273- Patch 1433928:
2274 - The copy module now "copies" function objects (as atomic objects).
2275 - dict.__getitem__ now looks for a __missing__ hook before raising
2276 KeyError.
2277
Tim Peters84ef21c2006-02-28 20:39:06 +00002278- PEP 343: with statement implemented. Needs ``from __future__ import
2279 with_statement``. Use of 'with' as a variable will generate a warning.
2280 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002281 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002282 The following objects have __context__ methods:
2283 - The built-in file type.
2284 - The thread.LockType type.
2285 - The following types defined by the threading module:
2286 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2287 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002288
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002289- Fix the encodings package codec search function to only search
2290 inside its own package. Fixes problem reported in patch #1433198.
2291
2292 Note: Codec packages should implement and register their own
2293 codec search function. PEP 100 has the details.
2294
Tim Peters9ea89d22006-06-04 03:26:02 +00002295- PEP 353: Using ``Py_ssize_t`` as the index type.
2296
2297- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2298 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2299 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2300 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2301 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002302
Neal Norwitzfc76d632006-01-10 06:03:13 +00002303- Patch #1400181, fix unicode string formatting to not use the locale.
2304 This is how string objects work. u'%f' could use , instead of .
2305 for the decimal point. Now both strings and unicode always use periods.
2306
Neal Norwitz671b9e32006-01-09 07:07:12 +00002307- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2308 configure would break checking curses.h.
2309
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002310- Bug #959576: The pwd module is now builtin. This allows Python to be
2311 built on UNIX platforms without $HOME set.
2312
Neal Norwitzc10978f2005-12-19 06:07:16 +00002313- Bug #1072182, fix some potential problems if characters are signed.
2314
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002315- Bug #889500, fix line number on SyntaxWarning for global declarations.
2316
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002317- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2318
Neal Norwitze7214a12005-12-18 05:03:17 +00002319- Support for converting hex strings to floats no longer works.
2320 This was not portable. float('0x3') now raises a ValueError.
2321
Barry Warsaw2a38a862005-12-18 01:27:35 +00002322- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002323 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002324 is now displayed in interactive prompt banner.
2325
Georg Brandlfa166682005-12-17 21:45:17 +00002326- Implementation of PEP 341 - Unification of try/except and try/finally.
2327 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002328 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002329
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002330- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2331 now encodes backslash correctly.
2332
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002333- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2334
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002335- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002336 and long longs.
2337
Neal Norwitz67715f02005-11-09 06:59:35 +00002338- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002339 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002340 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002341
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002342- Replaced most Unicode charmap codecs with new ones using the
2343 new Unicode translate string feature in the builtin charmap
2344 codec; the codecs were created from the mapping tables available
2345 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2346 encodings now include a mapping for the Apple logo)
2347
Tim Peterse3547fd2005-12-16 23:13:57 +00002348- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002349
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002350- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002351
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002352- A new AST parser implementation was completed. The abstract
2353 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002354 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002355
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002356- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002357 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2358
Neal Norwitz708e51a2005-10-03 04:48:15 +00002359- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2360
Neal Norwitz11bd1192005-10-03 00:54:56 +00002361- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2362 Provide a warning when a directory is passed on the command line.
2363
Neal Norwitz40d37812005-10-02 01:48:49 +00002364- Fix segfault with invalid coding.
2365
2366- SF bug #772896: unknown encoding results in MemoryError.
2367
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002368- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002369 supported a __len__() method which evaluated to False when the iterator
2370 was empty.
2371
Guido van Rossum630db602005-09-20 18:49:54 +00002372- On 64-bit platforms, when __len__() returns a value that cannot be
2373 represented as a C int, raise OverflowError.
2374
Skip Montanarof8948ca2005-09-19 03:54:46 +00002375- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002376 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002377
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002378- SF bug #893549: parsing keyword arguments was broken with a few format
2379 codes.
2380
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002381- Changes donated by Elemental Security to make it work on AIX 5.3
2382 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2383 bug #105470: test_pwd fails on 64bit system (Opteron).
2384
Guido van Rossum539c6622005-09-14 17:49:54 +00002385- Changes donated by Elemental Security to make it work on HP-UX 11 on
2386 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2387
Georg Brandl4550b8d2005-08-26 06:43:52 +00002388- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002389 (fixes bug #1119418).
2390
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002391- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2392
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002393- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2394 exceptions that cause a function to exit.
2395
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002396- The implementation of set() and frozenset() was revised to use its
2397 own internal data structure. Memory consumption is reduced by 1/3
2398 and there are modest speed-ups as well. The API is unchanged.
2399
Tim Petersde7990b2005-07-17 23:45:23 +00002400- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2401
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002402- SF bug #1229429: PyObject_CallMethod failed to decrement some
2403 reference counts in some error exit cases.
2404
Tim Petersecc6e6a2005-07-10 22:30:55 +00002405- SF bug #1185883: Python's small-object memory allocator took over
2406 a block managed by the platform C library whenever a realloc specified
2407 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002408 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002409 portable way to copy data from the C-managed block into Python's
2410 small-object space without risking a memory fault. Python's small-object
2411 realloc now leaves such blocks under the control of the platform C
2412 realloc.
2413
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002414- SF bug #1232517: An overflow error was not detected properly when
2415 attempting to convert a large float to an int in os.utime().
2416
Raymond Hettinger3296e692005-06-29 23:29:56 +00002417- SF bug #1224347: hex longs now print with lowercase letters just
2418 like their int counterparts.
2419
Michael W. Hudson188d4362005-06-20 16:52:57 +00002420- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2421 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2422 interpreter states; back out that fix and do a better job (see
2423 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2424 for a longer write-up of the problem).
2425
Michael W. Hudsondf888462005-06-03 14:41:55 +00002426- SF patch #1180995: marshal now uses a binary format by default when
2427 serializing floats.
2428
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002429- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2430 the routines that promise to produce IEEE 754 binary representations
2431 of floats now simply copy bytes around.
2432
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002433- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2434 278.
2435
Brett Cannonc3647ac2005-04-26 03:45:26 +00002436- patch #1109424: int, long, float, complex, and unicode now check for the
2437 proper magic slot for type conversions when subclassed. Previously the
2438 magic slot was ignored during conversion. Semantics now match the way
2439 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002440 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002441 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002442 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002443
Barry Warsawc8d907c2005-04-19 23:43:40 +00002444- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2445 NULL, now raise an AttributeError when attempting to set or delete the
2446 attribute. Previously a TypeError was raised, but this was inconsistent
2447 with the equivalent pure-Python implementation.
2448
Michael W. Hudson774479c2005-04-18 08:46:17 +00002449- It is now safe to call PyGILState_Release() before
2450 PyEval_InitThreads() (note that if there is reason to believe there
2451 are multiple threads around you still must call PyEval_InitThreads()
2452 before using the Python API; this fix is for extension modules that
2453 have no way of knowing if Python is multi-threaded yet).
2454
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002455- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2456 disabled caused a crash.
2457
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002458- Bug #1165306: instancemethod_new allowed the creation of a method
2459 with im_class == im_self == NULL, which caused a crash when called.
2460
Tim Petersecc6e6a2005-07-10 22:30:55 +00002461- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002462 fixes the crash seen in bug #1165761
2463
Raymond Hettinger96229b12005-03-11 06:49:40 +00002464- Added two new builtins, any() and all().
2465
Brett Cannon409d8f22005-03-05 06:47:57 +00002466- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002467 (e.g., ``class C(): pass`` is no longer a syntax error).
2468 Patch #1176012 added support to the 'parser' module and 'compiler' package
2469 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002470
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002471- Patch #1115086: Support PY_LONGLONG in structmember.
2472
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002473- Bug #1155938: new style classes did not check that __init__() was
2474 returning None.
2475
Tim Petersecc6e6a2005-07-10 22:30:55 +00002476- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002477 ('\') with a specific error message.
2478
Martin v. Löwisff232d72005-03-03 09:24:38 +00002479- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2480
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002481- Bug #1124295: the __name__ attribute of file objects was
2482 inadvertently made inaccessible in restricted mode.
2483
Tim Petersecc6e6a2005-07-10 22:30:55 +00002484- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002485 an ferror() call.
2486
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002487- min() and max() now support key= arguments with the same meaning as in
2488 list.sort().
2489
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002490- The peephole optimizer now performs simple constant folding in expressions:
2491 (2+3) --> (5).
2492
Raymond Hettingera422c342005-01-11 03:03:27 +00002493- set and frozenset objects can now be marshalled. SF #1098985.
2494
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002495- Bug #1077106: Poor argument checking could cause memory corruption
2496 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002497
Jeremy Hyltonab630502005-02-04 18:44:06 +00002498- The parser did not complain about future statements in illegal
2499 positions. It once again reports a syntax error if a future
2500 statement occurs after anything other than a doc string.
2501
Neil Schemenauercf52c072005-08-12 17:34:58 +00002502- Change the %s format specifier for str objects so that it returns a
2503 unicode instance if the argument is not an instance of basestring and
2504 calling __str__ on the argument returns a unicode instance.
2505
Tim Petersf4e69282006-02-27 17:15:31 +00002506- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2507 current thread state when the auto-GIL-state machinery knows about
2508 it (since the thread state is being deleted, continuing to remember it
2509 can't help, but can hurt if another thread happens to get created with
2510 the same thread id).
2511
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002512Extension Modules
2513-----------------
2514

Georg Brandlbc45a3f2006-03-17 19:17:34 +00002524
Neal Norwitz10be10c2006-03-16 06:50:13 +00002525- Everything under lib-old was removed. This includes the following modules:
2526 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002527 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002528 util, whatsound, whrandom, zmod
2529
2530- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2531
2532- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002533 is deprecated. The undocumented re.engine variable no longer exists.
2534
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002535- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2536 SS2 (single-shift 2) escape sequences correctly.
2537
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002538- The unicodedata module was updated to the 4.1 version of the Unicode
2539 database. The 3.2 version is still available as unicodedata.db_3_2_0
2540 for applications that require this specific version (such as IDNA).
2541
Neal Norwitzb62c4332006-03-04 18:35:47 +00002542- The timing module is no longer built by default. It was deprecated
2543 in PEP 4 in Python 2.0 or earlier.
2544
Guido van Rossum1968ad32006-02-25 22:38:04 +00002545- Patch 1433928: Added a new type, defaultdict, to the collections module.
2546 This uses the new __missing__ hook behavior added to dict (see above).
2547
Georg Brandldbd83392006-02-20 09:42:33 +00002548- Bug #854823: socketmodule now builds on Sun platforms even when
2549 INET_ADDRSTRLEN is not defined.
2550
Georg Brandlf4f44152006-02-18 22:29:33 +00002551- Patch #1393157: os.startfile() now has an optional argument to specify
2552 a "command verb" to invoke on the file.
2553
Neal Norwitz082b2df2006-02-07 07:04:46 +00002554- Bug #876637, prevent stack corruption when socket descriptor
2555 is larger than FD_SETSIZE.
2556
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002557- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2558 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2559 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
2560
Martin v. Löwis57a34e82006-02-04 19:12:37 +00002561- Patch #1422385: The nis module now supports access to domains other
2562 than the system default domain.
2563
Martin v. Löwis14694662006-02-03 12:54:16 +00002564- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2565 are reported, the limit on path name lengths is removed, and stat reports
2566 WindowsError now (instead of OSError).
2567
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002568- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
2569
Neal Norwitz62a21122006-01-25 05:21:55 +00002570- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
2571 before the env.

2578 Also fix ungetmouse() which did not accept arguments properly.
2579 The code now conforms to the documented signature.
2580
Neal Norwitz5e3d8622006-01-09 06:24:35 +00002581- Bug #1400115, Fix segfault when calling curses.panel.userptr()
2582 without prior setting of the userptr.
2583

2643 the request code argument, which results in more C-like behaviour
2644 for large or negative values.
2645

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002702- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2703 been renamed to have only a single underscore prefix. This was done to
2704 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002705
Nick Coghlan43832302006-04-23 17:04:07 +00002706- PEP 338: new module runpy defines a run_module function to support
2707 executing modules which provide access to source code or a code object
2708 via the PEP 302 import mechanisms.
2709
Anthony Baxter93f5b932006-04-03 08:05:07 +00002710- The email module's parsedate_tz function now sets the daylight savings
2711 flag to -1 (unknown) since it can't tell from the date whether it should

2718 in attribute values.
2719
Anthony Baxterc51ee692006-04-01 00:57:31 +00002720- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002721 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002722 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002723 module will not be built.
2724
Tim Petersc17976e2006-04-01 00:26:53 +00002725- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2726 aren't officially supported here, and trying to use them will probably
2727 raise an exception some day. But dicts have been allowed, and "mostly
2728 worked", so support for them won't go away without warning.
2729
Georg Brandl338ef7d2006-03-31 18:42:16 +00002730- Bug #1445068: getpass.getpass() can now be given an explicit stream
2731 argument to specify where to write the prompt.
2732

2740
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002741- Queue.Queue objects now support .task_done() and .join() methods
2742 to make it easier to monitor when daemon threads have completed
2743 processing all enqueued tasks. Patch #1455676.
2744

2748
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002749- email 4.0 package now integrated. This is largely the same as the email 3.0
2750 package that was included in Python 2.3, except that PEP 8 module names are
2751 now used (e.g. mail.message instead of email.Message). The MIME classes
2752 have been moved to a subpackage (e.g. email.mime.text instead of
2753 email.MIMEText). The old names are still supported for now. Several
2754 deprecated Message methods have been removed and lots of bugs have been
2755 fixed. More details can be found in the email package documentation.
2756
Walter Dörwald40108c92006-03-27 08:15:44 +00002757- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2758 (a subclass of tuple) that provides incremental decoders and encoders
2759 (a way to use stateful codecs without the stream API). Python functions
2760 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2761 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2762 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002763
Walter Dörwald067db482006-03-15 22:17:27 +00002764- Patch #1359365: Calling next() on a closed StringIO.String object raises
2765 a ValueError instead of a StopIteration now (like file and cString.String do).
2766 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2767 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002768
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002769- A regrtest option -w was added to re-run failed tests in verbose mode.

2773
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002774- The function get_count() has been added to the gc module, and gc.collect()
2775 grew an optional 'generation' argument.
2776

2779
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002780- PEP 343: new module contextlib.py defines decorator @contextmanager
2781 and helpful context managers nested() and closing().
2782

Martin v. Löwis3e865952006-01-24 15:51:21 +00002817 specifications, raises IOErrors when proxies for unsupported protocols
2818 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002841 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2842 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2843 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2844 Ronald L. Rivest offered this advice for Python:
2845
2846 "The consensus of researchers in this area (at least as
2847 expressed at the NIST Hash Function Workshop 10/31/05),
2848 is that SHA-256 is a good choice for the time being, but
2849 that research should continue, and other alternatives may
2850 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002851
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002852- Added a subset of Fredrik Lundh's ElementTree package. Available

2905 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002906 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002907

2927
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002928- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2929 to W3C name (404 -> 'Not Found'). RFE #1216944.
2930
Georg Brandl9e43acf2005-07-04 17:16:07 +00002931- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2932 as this can cause problems with apps closing all file descriptors.

2945 Bug #1224621.
2946
Raymond Hettinger68c04532005-06-10 11:05:19 +00002947- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002948 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002949 the generate_tokens() function now accepts a callable argument that
2950 terminates by raising StopIteration.
2951
Georg Brandl9166e1a2005-06-04 09:20:03 +00002952- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2953
Georg Brandl268e61c2005-06-03 14:28:50 +00002954- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2955 component of the path.
2956
Skip Montanaro174dd222005-05-14 20:54:16 +00002957- Patch #1120353: The xmlrpclib module provides better, more transparent,
2958 support for datetime.{datetime,date,time} objects. With use_datetime set
2959 to True, applications shouldn't have to fiddle with the DateTime wrapper
2960 class at all.
2961
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002962- distutils.commands.upload was added to support uploading distribution
2963 files to PyPI.
2964
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002965- distutils.commands.register now encodes the data as UTF-8 before posting
2966 them to PyPI.
2967
Raymond Hettinger267b8682005-03-27 10:47:39 +00002968- decimal operator and comparison methods now return NotImplemented
2969 instead of raising a TypeError when interacting with other types. This
2970 allows other classes to implement __radd__ style methods and have them
2971 work as expected.
2972
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002973- Bug #1163325: Decimal infinities failed to hash. Attempting to
2974 hash a NaN raised an InvalidOperation instead of a TypeError.
2975
Tim Petersecc6e6a2005-07-10 22:30:55 +00002976- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002977 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2978

3010
Guido van Rossumd0641422005-02-03 15:01:24 +00003011- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3012 disables recursive traversal through instance attributes, which can
3013 be exploited in various ways.
3014
Tim Peterse3547fd2005-12-16 23:13:57 +00003015- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003016 flags on the HTTP listening socket.
3017
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003018- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3019 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3020
Fred Drakefbdeaad2006-07-29 16:56:15 +00003021- Patches #893642, #1039083: add allow_none, encoding arguments to
3022 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003023
Martin v. Löwis1d11de62005-01-29 13:29:23 +00003024- Bug #1110478: Revert os.environ.update to do putenv again.
3025
Thomas Hellerd6c6e222005-01-20 19:20:16 +00003026- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3027
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003028- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3029
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003030- Enhancements to the csv module:
3031
3032 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003033 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003034 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003035 + Dialect parameter parsing has been re-implemented to improve error
3036 reporting.
3037 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3038 dictates.
3039 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003040 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003041 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003042 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3043 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003044 + reader now allows \r characters to be quoted (previously it only allowed
3045 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003046 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003047 + Dialect classes passed to the module are no longer instantiated by
3048 the module before being parsed (the former validation scheme required
3049 this, but the mechanism was unreliable).
3050 + The dialect registry now contains instances of the internal
3051 C-coded dialect type, rather than references to python objects.
3052 + the internal c-coded dialect type is now immutable.
3053 + register_dialect now accepts the same keyword dialect specifications
3054 as the reader and writer, allowing the user to register dialects
3055 without first creating a dialect class.
3056 + a configurable limit to the size of parsed fields has been added -
3057 previously, an unmatched quote character could result in the entire
3058 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003059 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003060 the parser field size limit (returning the former limit). The initial
3061 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003062 + A line_num attribute has been added to the reader object, which tracks
3063 the number of lines read from the source iterator. This is not
3064 the same as the number of records returned, as records can span
3065 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003066 + reader and writer objects were not being registered with the cyclic-GC.
3067 This has been fixed.
3068
Brett Cannone6539c42005-01-08 02:43:53 +00003069- _DummyThread objects in the threading module now delete self.__block that is
3070 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3071 lock primitives tend to be limited in number and thus should not be wasted on
3072 a _DummyThread object. Fixes bug #1089632.
3073
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003074- The imghdr module now detects Exif files.
3075
Raymond Hettinger6065d322004-12-20 23:51:53 +00003076- StringIO.truncate() now correctly adjusts the size attribute.
3077 (Bug #951915).
3078
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003079- locale.py now uses an updated locale alias table (built using
3080 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3081 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003082 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003083
Raymond Hettinger3557f422004-12-07 12:02:02 +00003084- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3085
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003086- the pickle module no longer accepts the deprecated None option in the
3087 args tuple returned by __reduce__().
3088
Brett Cannon84667c02004-12-07 03:25:18 +00003089- optparse now optionally imports gettext. This allows its use in setup.py.
3090
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003091- the pickle module no longer uses the deprecated bin parameter.
3092
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003093- the shelve module no longer uses the deprecated binary parameter.
3094
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003095- the pstats module no longer uses the deprecated ignore() method.
3096
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003097- the filecmp module no longer uses the deprecated use_statcache argument.
3098
Raymond Hettinger664347b2004-12-04 21:21:53 +00003099- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3100 extended or overridden by subclasses. Formerly, the subclassed method would
3101 be ignored by the rest of the module. (Bug #1078905).
3102
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003103- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003104 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003105
Walter Dörwald36733692004-12-22 12:50:50 +00003106- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3107 once when a size argument is given. This prevents a buffer overflow in the
3108 tokenizer with very long source lines.
3109
Barry Warsaw538561e2006-01-01 21:48:54 +00003110- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3111 immediately after creating the object, without any intervening
3112 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003113
Skip Montanaro05885812005-01-16 20:48:27 +00003114- The reconvert.quote function can now emit triple-quoted strings. The
3115 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003116
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003117- ``UserString.MutableString`` now supports negative indices in
3118 ``__setitem__`` and ``__delitem__``
3119
Greg Ward40407942005-03-05 02:53:17 +00003120- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3121 correctly.
3122
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003123- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3124 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3125 character even if the user has passed a size parameter to get a proper
3126 line ending. Remove the special handling of a "\r\n" that has been split
3127 between two lines.
3128
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003129- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3130 about illegal code points. The codec now supports PEP 293 style error
3131 handlers.
3132
Walter Dörwald78a78b02005-09-01 12:04:29 +00003133- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003134 from the input stream, so that the output is a byte string in the correct
3135 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003136
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003137- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3138 considering it exactly like a '*'.
3139
Walter Dörwald007f8df2005-10-09 19:42:27 +00003140- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3141 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003142
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003143- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3144
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003145- Patch #1413711: Certain patterns of differences were making difflib
3146 touch the recursion limit.
3147
Walter Dörwald58917a62006-03-31 15:26:22 +00003148- Bug #947906: An object oriented interface has been added to the calendar
3149 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003150 called as a script (e.g. via ``python -mcalendar``). Localized month and
3151 weekday names can be ouput (even if an exotic encoding is used) using
3152 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003153

3155-----
3156
Neal Norwitz602d3392006-03-31 08:21:40 +00003157- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3158 by using -mieee gcc option.
3159

3161
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003162- Build support for Win64-AMD64 was added.
3163
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003164- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3165
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003166- Patch #881820: look for openpty and forkpty also in libbsd.
3167
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003168- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3169 The zlib module is now builtin on Windows.
3170
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003171- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3172
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003173- Bug #1189330: configure did not correctly determine the necessary
3174 value of LINKCC if python was built with GCC 4.0.
3175
Trent Mick8321b422005-07-26 02:29:21 +00003176- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3177 vulnerability in zlib 1.2.1 and 1.2.2.
3178
Brett Cannon08cd5982005-04-24 22:26:38 +00003179- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3180 flags that change binary compatibility. Changes were also made to
3181 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003182 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003183
Bob Ippolitoed233462005-03-29 13:47:59 +00003184- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3185 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3186 no longer exists). This configure patch makes things right.
3187
Martin v. Löwise2713be2005-03-08 15:03:08 +00003188- Bug #1158607: Build with --disable-unicode again.
3189
Brett Cannon46d96232005-02-16 00:07:19 +00003190- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3191 defined. Discovered as a result of not being able to build on OS X.
3192
Brett Cannon516592f2004-12-07 00:42:59 +00003193- setup.py now uses the directories specified in LDFLAGS using the -L option
3194 and in CPPFLAGS using the -I option for adding library and include
3195 directories, respectively, for compiling extension modules against. This has
3196 led to the core being compiled using the values in CPPFLAGS. It also removes
3197 the need for the special-casing of both DarwinPorts and Fink for darwin since
3198 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3199 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3200 Fink, ``-I/opt/local/include`` for DarwinPorts).
3201
Brett Cannon43802422005-02-10 20:48:03 +00003202- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3203 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3204 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3205 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003207C API
3208-----
3209
Tim Petersc9d78aa2006-03-26 23:27:58 +00003210- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3211 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3212 is obtained via the ``PyObject_`` family, it must be released via the
3213 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3214 always been officially true, but when Python's small-object allocator was
3215 introduced, an attempt was made to cater to a few extension modules
3216 discovered at the time that obtained memory via ``PyObject_New`` but
3217 released it via ``PyMem_DEL``. It's years later, and if such code still
3218 exists it will fail now (probably with segfaults, but calling wrong
3219 low-level memory management functions can yield many symptoms).
3220
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003221- Added a C API for set and frozenset objects.
3222
Raymond Hettinger66517482004-12-03 11:45:13 +00003223- Removed PyRange_New().
3224
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003225- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3226 mapping argument now. This string is used as a mapping table. Byte values
3227 greater than the length of the string and 0xFFFE are treated as undefined
3228 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00003234- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003235
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003236- Patch #1276356: New resource "urlfetch" is implemented. This enables
3237 even impatient people to run tests that require remote files.
