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

78
Brett Cannonff931572008-07-13 01:20:19 +000079- Issue #3339: dummy_thread.acquire() could return None which is not a valid
80 return value.
81
Raymond Hettinger75ee9eb2008-06-16 01:49:18 +000082- Issue #3116 and #1792: Fix quadratic behavior in marshal.dumps().

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

108
Martin v. Löwis0e305552008-03-06 07:14:26 +0000109- Bug #1725737: In distutil's sdist, exclude RCS, CVS etc. also in the
110 root directory, and also exclude .hg, .git, .bzr, and _darcs.
111
Andrew M. Kuchling37d4f7b2008-02-23 19:06:54 +0000112- Bug #1389051: imaplib causes excessive memory fragmentation when reading

Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000116 calling .read() on a socket object wrapped with makefile().
Andrew M. Kuchling664553a2008-02-23 19:30:59 +0000117
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +0000118- Bug #1433694: minidom's .normalize() failed to set .nextSibling for
119 last child element.
120
Gregory P. Smith26660402008-06-01 23:44:46 +0000121- Issue #2791: subprocess.Popen.communicate explicitly closes its
122 stdout and stderr fds rather than leaving them open until the
123 instance is destroyed.
124
Gregory P. Smithf8f30fa2008-07-06 04:04:07 +0000125- Issue #2632: Prevent socket.read(bignumber) from over allocating memory
126 in the common case when the data is returned from the underlying socket
127 in increments much smaller than bignumber.
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +0000128

188
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000189- Issue #1920: "while 0" statements were completely removed by the compiler,
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000190 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000191 the condition is false. Now the compiler correctly emits bytecode for the

1161 now issue a UnicodeWarning and interpret the two objects as
1162 unequal. The UnicodeWarning can be filtered as desired using
1163 the warning framework, e.g. silenced completely, turned into an
1164 exception, logged, etc.
1165
1166 Note that compare operators other than equal and unequal will still
1167 raise UnicodeDecodeError exceptions as they've always done.

Marc-André Lemburg757ea272006-08-14 11:44:34 +00001169- Fix segfault when doing string formatting on subclasses of long.
1170
1171- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1172 with new-style classes.
1173
1174- Fix bug related to __len__ functions returning negative values with
1175 classic classes.
1176
1177- Patch #1538606, Fix __index__() clipping. There were some problems
1178 discovered with the API and how integers that didn't fit into Py_ssize_t
1179 were handled. This patch attempts to provide enough alternatives
1180 to effectively use __index__.
1181
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001182- Bug #1536021: __hash__ may now return long int; the final hash
1183 value is obtained by invoking hash on the long int.
1184
Thomas Hellerab1049c2006-08-08 17:37:00 +00001185- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1186
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001187- Bug #1535165: fixed a segfault in input() and raw_input() when
1188 sys.stdin is closed.
1189
Thomas Heller74d36f02006-08-04 18:17:40 +00001190- On Windows, the PyErr_Warn function is now exported from
1191 the Python dll again.
1192
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001193- Bug #1191458: tracing over for loops now produces a line event
1194 on each iteration. Fixing this problem required changing the .pyc
1195 magic number. This means that .pyc files generated before 2.5c1
1196 will be regenerated.
1197
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001198- Bug #1333982: string/number constants were inappropriately stored
1199 in the byte code and co_consts even if they were not used, ie
1200 immediately popped off the stack.
1201
Georg Brandle9462c72006-08-04 18:03:37 +00001202- Fixed a reference-counting problem in property().

1205Library
1206-------
1207
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001208- Fix a bug in the ``compiler`` package that caused invalid code to be
1209 generated for generator expressions.
1210
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001211- The distutils version has been changed to 2.5.0. The change to
1212 keep it programmatically in sync with the Python version running
1213 the code (introduced in 2.5b3) has been reverted. It will continue
1214 to be maintained manually as static string literal.
1215
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001216- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001217 and this cannot be converted to the required C type, an exception is
1218 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001219 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001220
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001221- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001222 an exception.
1223
Tim Peterscbdd3502006-09-05 01:47:53 +00001224- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001225 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001226 workarounds for clocks with low resolution, to stop the code yielding
1227 duplicate UUIDs.
1228
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001229- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1230 before raising SystemExit, allowing IDLE to honor quit() and exit().
1231
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001232- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1233
Georg Brandl7a1af772006-08-14 21:55:28 +00001234- Patch #1536071: trace.py should now find the full module name of a
1235 file correctly even on Windows.
1236
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001237- logging's atexit hook now runs even if the rest of the module has
1238 already been cleaned up.
1239
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001240- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001241
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001242- Bug #1531405, format_exception no longer raises an exception if
1243 str(exception) raised an exception.
1244
Neil Schemenauer06ded092006-08-04 16:20:30 +00001245- Fix a bug in the ``compiler`` package that caused invalid code to be
1246 generated for nested functions.

1253
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001254- Patch #1511317: don't crash on invalid hostname (alias) info.
1255
Georg Brandl3335a7a2006-08-14 21:42:55 +00001256- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1257 raises the correct exceptions.
1258
Thomas Heller1ce433e2006-08-14 16:20:04 +00001259- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1260 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1261
Thomas Heller86720042006-08-14 11:17:48 +00001262- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1263 uses the _as_parameter_ attribute when objects are passed to foreign
1264 function calls. The ctypes version number was changed to 1.0.1.
1265
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001266- Bug #1530559, struct.pack raises TypeError where it used to convert.
1267 Passing float arguments to struct.pack when integers are expected
1268 now triggers a DeprecationWarning.
1269

1273
Neal Norwitzb476fdf2006-08-15 04:58:28 +00001274- test_socketserver should now work on cygwin and not fail sporadically
1275 on other platforms.
1276
Neal Norwitz003c9e22006-08-11 06:09:41 +00001277- test_mailbox should now work on cygwin versions 2006-08-10 and later.

1292-----
1293
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001294- Bug #1535502, build _hashlib on Windows, and use masm assembler
1295 code in OpenSSL.
1296
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001297- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.
1298
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001299- Bug #1530448, ctypes build failure on Solaris 10 was fixed.
Thomas Heller17984892006-08-04 18:57:34 +00001300

Tim Peters4643c2f2006-08-10 22:45:34 +00001302C API
1303-----
1304
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001305- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1306
Tim Peters4643c2f2006-08-10 22:45:34 +00001307- Bug #1069160. Internal correctness changes were made to
1308 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1309 the documentation was changed to state that the return value
1310 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001313What's New in Python 2.5 beta 3?
1314================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001315
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001316*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001317
1318Core and builtins
1319-----------------
1320
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001321- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001322 returned a long (see PEP 353).
1323
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001324- Bug #1515471: string.replace() accepts character buffers again.
1325
Neal Norwitz07aadb12006-07-30 06:55:48 +00001326- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1327 This provides the proper warning for struct.pack().
1328 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1329
Neal Norwitz0d62a062006-07-30 06:53:31 +00001330- Patch #1531113: Fix augmented assignment with yield expressions.
1331 Also fix a SystemError when trying to assign to yield expressions.
1332
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001333- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1334 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1335 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1336 excessive filesystem operations during imports.
1337
Tim Petersbc24eee2006-07-27 01:14:53 +00001338- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1339 operations on signed longs that are formally undefined by C.
1340 Unfortunately, at least one compiler now cares about that, so complicated
1341 the code to make that compiler happy again.
1342
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001343- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1344
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001345- Patch #1232023: Stop including current directory in search
1346 path on Windows.
1347
Neal Norwitze1fdb322006-07-21 05:32:28 +00001348- Fix some potential crashes found with failmalloc.
1349
Neal Norwitze7563102006-07-17 01:00:16 +00001350- Fix warnings reported by Klocwork's static analysis tool.
1351
Neal Norwitz84be93b2006-07-16 01:50:38 +00001352- Bug #1512814, Fix incorrect lineno's when code within a function
1353 had more than 255 blank lines.
1354
Georg Brandl9dceedb2006-07-12 15:31:17 +00001355- Patch #1521179: Python now accepts the standard options ``--help`` and
1356 ``--version`` as well as ``/?`` on Windows.
1357
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001358- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001359 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001360 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001361
Tim Peters112aad32006-07-19 00:03:19 +00001362- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001363 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001364 new ``sys._current_frames()`` returns a dictionary with one entry,
1365 mapping the faux "thread id" 0 to the current frame.
1366
Ronald Oussoren3075e162006-07-25 20:28:55 +00001367- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001368
Ronald Oussoren3075e162006-07-25 20:28:55 +00001369
Neal Norwitza1f10902006-07-12 07:28:29 +00001370Library
1371-------
1372
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001373- Correction of patch #1455898: In the mbcs decoder, set final=False
1374 for stream decoder, but final=True for the decode function.
1375
Georg Brandl07fec3a2006-08-01 18:49:24 +00001376- os.urandom no longer masks unrelated exceptions like SystemExit or
1377 KeyboardInterrupt.
1378
Tim Peters4643c2f2006-08-10 22:45:34 +00001379- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001380 shutil.copytree on Windows
1381
Georg Brandle34ac7c2006-07-30 11:07:23 +00001382- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1383 refers to file descriptors, not file objects.
1384
Tim Peterscbdd3502006-09-05 01:47:53 +00001385- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001386 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001387 #1513611, and probably others.
1388
Georg Brandledd9b0d2006-07-29 09:33:26 +00001389- Bug #1441397: The compiler module now recognizes module and function
1390 docstrings correctly as it did in Python 2.4.
1391
Tim Peters6f681472006-07-27 23:44:37 +00001392- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1393 lost that tests are sorted by name before being run. This rarely
1394 matters for well-written tests, but can create baffling symptoms if
1395 side effects from one test to the next affect outcomes. ``DocTestFinder``
1396 has been changed to sort the list of tests it returns.
1397
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001398- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001399 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001400
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001401- Bug #978833: Really close underlying socket in _socketobject.close.
1402
Georg Brandldb232dc2006-08-20 13:15:43 +00001403- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1404 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001405
Georg Brandlcf0c1722006-07-26 07:23:32 +00001406- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1407 to recursive calls and call it with the failing package name.
1408
Martin v. Löwis0b483032006-07-25 09:53:12 +00001409- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1410
Georg Brandlc13c34c2006-07-24 14:09:56 +00001411- Patch #1515343: Fix printing of deprecated string exceptions with a
1412 value in the traceback module.
1413
Greg Ward48fae7a2006-07-23 16:05:51 +00001414- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1415
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001416- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1417
Brett Cannoncaebe222006-07-18 04:41:36 +00001418- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1419 argument tuple. For arguments where zero is illegal, the value is forced to
1420 the minimum value that is correct. This is to support an undocumented but
1421 common way people used to fill in inconsequential information in the time
1422 tuple pre-2.4.
1423
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001424- Patch #1220874: Update the binhex module for Mach-O.
1425
Barry Warsawb110bad2006-07-21 14:51:07 +00001426- The email package has improved RFC 2231 support, specifically for
1427 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1428 (name*0=<blah>) parameter continuations. This may change the types of
1429 values returned from email.message.Message.get_param() and friends.
1430 Specifically in some cases where non-encoded continuations were used,
1431 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1432 will just return the string (since non-encoded continuations don't have
1433 charset and language parts).
1434
1435 Also, whereas % values were decoded in all parameter continuations, they are
1436 now only decoded in encoded parameter parts.
1437
Ronald Oussoren3075e162006-07-25 20:28:55 +00001438- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1439
1440- Bug #1517996: IDLE now longer shows the default Tk menu when a
1441 path browser, class browser or debugger is the frontmost window on MacOS X
1442
Barry Warsaw00decd72006-07-27 23:43:15 +00001443- Patch #1520294: Support for getset and member descriptors in types.py,
1444 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1445 of an object against these built-in types and more importantly, for getting
1446 their docstrings printed in the interactive interpreter's help() function.

1450-----------------
1451
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001452- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1453 a socket operation on a socket with a timeout, the exception will be
1454 caught correctly. Previously, the exception was not caught.
1455
Thomas Heller1393d6a2006-07-28 21:43:20 +00001456- Patch #1529514: The _ctypes extension is now compiled on more
1457 openbsd target platforms.
1458
Tim Peters9cab5932006-07-28 00:30:00 +00001459- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1460 a memory leak, affecting pickles and deep copies.
1461
Tim Petersbc24eee2006-07-27 01:14:53 +00001462- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1466
Thomas Hellerce049a02006-07-14 17:51:14 +00001467- Patch #1521817: Index range checking on ctypes arrays containing
1468 exactly one element enabled again. This allows iterating over these
1469 arrays, without the need to check the array size before.
1470
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001471- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001472 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001473 /dev/null in certain cases; this is now fixed.
1474
Thomas Heller47d7a062006-07-12 08:43:47 +00001475- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1476 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001477
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001478- Because of a misspelled preprocessor symbol, ctypes was always
1479 compiled without thread support; this is now fixed.
1480
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001481- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1482 methods now allow their database parameter to be None as the
1483 sleepycat API allows.
1484
Matt Flemingec926502006-07-28 11:27:27 +00001485- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1486 bluetooth API compared with Linux and FreeBSD.
1487
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001488Tests
1489-----
1490
1491- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1492 how long the test file should take to play. Now accepts taking 2.93 secs
1493 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1494
Georg Brandl4793aa32006-07-28 18:31:39 +00001495- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1496 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1497 run via ``regrtest.py``. Now they do.

Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001499Build
1500-----
1501
1502- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1503
Ronald Oussoren26cad082006-08-01 21:00:57 +00001504Mac
1505---
1506
1507- PythonLauncher now works correctly when the path to the script contains
1508 characters that are treated specially by the shell (such as quotes).
1509
1510- Bug #1527397: PythonLauncher now launches scripts with the working directory
1511 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001512 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001513 expect.

1521Core and builtins
1522-----------------
1523
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001524- Bug #1441486: The literal representation of -(sys.maxint - 1)
1525 again evaluates to a int object, not a long.
1526
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001527- Bug #1501934: The scope of global variables that are locally assigned
1528 using augmented assignment is now correctly determined.
1529
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001530- Bug #927248: Recursive method-wrapper objects can now safely
1531 be released.
1532
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001533- Bug #1417699: Reject locale-specific decimal point in float()
1534 and atof().
1535
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001536- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1537 omit a default "error" argument for NULL pointer. This allows
1538 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001539
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001540- Bug #1519018: 'as' is now validated properly in import statements.
1541
Neal Norwitz28746ab2006-07-09 22:14:42 +00001542- On 64 bit systems, int literals that use less than 64 bits are
1543 now ints rather than longs.
1544
Neal Norwitzed657552006-07-10 00:04:44 +00001545- Bug #1512814, Fix incorrect lineno's when code at module scope
1546 started after line 256.
1547
Tim Peters32a83612006-07-10 21:08:24 +00001548- New function ``sys._current_frames()`` returns a dict mapping thread
1549 id to topmost thread stack frame. This is for expert use, and is
1550 especially useful for debugging application deadlocks. The functionality
1551 was previously available in Fazal Majid's ``threadframe`` extension
1552 module, but it wasn't possible to do this in a wholly threadsafe way from
1553 an extension.
1554

1562
Tim Peters32a83612006-07-10 21:08:24 +00001563- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001564 environment variable to be set in order to the SDK environment
1565 for finding the compiler, include files, etc.

1570
Thomas Woutersadd19112006-07-05 11:03:49 +00001571- string.Template() now correctly handles tuple-values. Previously,
1572 multi-value tuples would raise an exception and single-value tuples would
1573 be treated as the value they contain, instead.
1574
Martin v. Löwisede77f52006-07-03 13:01:35 +00001575- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1576 even if some data are received.
1577
Martin v. Löwis45482392006-07-03 12:28:58 +00001578- Bug #1267547: Put proper recursive setup.py call into the

1582 degrees and radians.
1583
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001584- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001585 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001586
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001587- Bug #1514703: Only setup canvas window in turtle when the canvas
1588 is created.
1589
Martin v. Löwis7596e832006-07-01 15:33:37 +00001590- Bug #1513223: .close() of a _socketobj now releases the underlying

1594 attribute values.
1595
1596- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1597 sgmllib ('[' and ']' were not accepted).
1598
Georg Brandl1be63af2006-06-28 20:23:25 +00001599- Fix a bug in the turtle module's end_fill function.
1600
Brett Cannon53ab5b72006-06-22 16:49:14 +00001601- Bug #1510580: The 'warnings' module improperly required that a Warning
1602 category be either a types.ClassType and a subclass of Warning. The proper
1603 check is just that it is a subclass with Warning as the documentation states.
1604
Georg Brandlad29e632006-06-21 17:45:17 +00001605- The compiler module now correctly compiles the new try-except-finally
1606 statement (bug #1509132).
1607
Neal Norwitz60373cd2006-06-22 06:30:50 +00001608- The wsgiref package is now installed properly on Unix.
1609
Vinay Sajip28e57612006-07-01 10:45:20 +00001610- A bug was fixed in logging.config.fileConfig() which caused a crash on
1611 shutdown when fileConfig() was called multiple times.
1612
Gerhard Häring762fbd32006-07-02 17:48:30 +00001613- The sqlite3 module did cut off data from the SQLite database at the first
1614 null character before sending it to a custom converter. This has been fixed
1615 now.
1616
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001617Extension Modules
1618-----------------
1619
Tim Peters112aad32006-07-19 00:03:19 +00001620- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1621 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1622 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001623
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001624- Assigning None to pointer type fields in ctypes structures possible
1625 overwrote the wrong fields, this is fixed now.
1626
1627- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1628 on non-Windows platforms.
1629
1630- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1631 integer or long, without range checking.
1632
1633- Patch #1517790: It is now possible to use custom objects in the ctypes
1634 foreign function argtypes sequence as long as they provide a from_param
1635 method, no longer is it required that the object is a ctypes type.
1636
1637- The '_ctypes' extension module now works when Python is configured
1638 with the --without-threads option.
1639
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001640- Bug #1513646: os.access on Windows now correctly determines write
1641 access, again.
1642
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001643- Bug #1512695: cPickle.loads could crash if it was interrupted with
1644 a KeyboardInterrupt.
1645
Neal Norwitza12aa882006-07-06 06:45:08 +00001646- Bug #1296433: parsing XML with a non-default encoding and
1647 a CharacterDataHandler could crash the interpreter in pyexpat.
1648
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001649- Patch #1516912: improve Modules support for OpenVMS.

1652-----
1653
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001654- Automate Windows build process for the Win64 SSL module.
1655
Tim Peters32a83612006-07-10 21:08:24 +00001656- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001657 Previously, the slight difference could cause compilation errors of the
1658 'zlib' module on systems with more than one version of zlib.
1659
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001660- The MSI compileall step was fixed to also support a TARGETDIR
1661 with spaces in it.
1662
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001663- Bug #1517388: sqlite3.dll is now installed on Windows independent

1676-------------
1677
Nick Coghlan2d792252006-07-06 13:47:18 +00001678- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1679 documentation for the warnings module.
1680
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001681- Patch #1509163: MS Toolkit Compiler no longer available.

1692-----------------
1693
Georg Brandla56b9152006-06-19 06:35:54 +00001694- Patch #1507676: Error messages returned by invalid abstract object operations
1695 (such as iterating over an integer) have been improved and now include the
1696 type of the offending object to help with debugging.
1697
Brett Cannonea3912b2006-06-13 21:46:41 +00001698- Bug #992017: A classic class that defined a __coerce__() method that returned
1699 its arguments swapped would infinitely recurse and segfault the interpreter.
1700
Neal Norwitz909eb122006-06-12 02:13:21 +00001701- Fix the socket tests so they can be run concurrently.
1702
Neal Norwitzb9845e72006-06-12 02:11:18 +00001703- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001704 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001705
Brett Cannon22565aa2006-06-09 22:31:23 +00001706- Bug #532646: object.__call__() will continue looking for the __call__
1707 attribute on objects until one without one is found. This leads to recursion
1708 when you take a class and set its __call__ attribute to an instance of the
1709 class. Originally fixed for classic classes, but this fix is for new-style.
1710 Removes the infinite_rec_3 crasher.
1711
Georg Brandl24250812006-06-09 18:45:48 +00001712- The string and unicode methods startswith() and endswith() now accept
1713 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1714
Brett Cannonde3b0522006-06-08 17:00:45 +00001715- Buffer objects, at the C level, never used the char buffer
1716 implementation even when the char buffer for the wrapped object was
1717 explicitly requested (originally returned the read or write buffer).
1718 Now a TypeError is raised if the char buffer is not present but is
1719 requested.
1720
Georg Brandlddbaa662006-06-04 21:56:52 +00001721- Patch #1346214: Statements like "if 0: suite" are now again optimized
1722 away like they were in Python 2.4.
1723
Georg Brandlb7c8f542006-05-27 12:30:25 +00001724- Builtin exceptions are now full-blown new-style classes instead of
1725 instances pretending to be classes, which speeds up exception handling
1726 by about 80% in comparison to 2.5a2.
1727
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001728- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1729 Unicode 4.1.
1730
Georg Brandlf4ef1162006-05-26 18:03:31 +00001731- Patch #921466: sys.path_importer_cache is now used to cache valid and
1732 invalid file paths for the built-in import machinery which leads to
1733 fewer open calls on startup.
1734
Tim Peters696cf432006-05-24 21:10:40 +00001735- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1736 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1737 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1738 the number of input digits (it was and remains linear-time for bases
1739 2, 4, 8, 16 and 32).
1740
Tim Petersb713ec22006-05-23 18:45:30 +00001741- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1742 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1743 an integer close to ``sys.maxint``. This was repaired by patch
1744 #1335972, which also gives a nice speedup.
1745
Richard Jonescebbefc2006-05-23 18:28:17 +00001746- Patch #1337051: reduced size of frame objects.
1747
1748- PyErr_NewException now accepts a tuple of base classes as its
1749 "base" parameter.
1750
Richard Jones7c88dcc2006-05-23 10:37:38 +00001751- Patch #876206: function call speedup by retaining allocated frame
1752 objects.
1753
Georg Brandl7b90e162006-05-18 07:01:27 +00001754- Bug #1462152: file() now checks more thoroughly for invalid mode
1755 strings and removes a possible "U" before passing the mode to the
1756 C library function.
1757
Neal Norwitz1004a532006-05-15 07:17:23 +00001758- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1759
Neal Norwitz373f0a72006-05-15 07:04:36 +00001760- Bug #1487966: Fix SystemError with conditional expression in assignment
1761
Martin v. Löwis879768d2006-05-11 13:28:43 +00001762- WindowsError now has two error code attributes: errno, which carries
1763 the error values from errno.h, and winerror, which carries the error
1764 values from winerror.h. Previous versions put the winerror.h values
1765 (from GetLastError()) into the errno attribute.
1766
Martin v. Löwis77736712006-05-04 05:51:03 +00001767- Patch #1475845: Raise IndentationError for unexpected indent.
1768
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001769- Patch #1479181: split open() and file() from being aliases for each other.
1770
Tim Peters44bd9862006-06-01 13:49:23 +00001771- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1772 methods were always silently ignored by dictionaries when comparing keys.
1773 They are now passed through (except when using the C API function
1774 ``PyDict_GetItem()``, whose semantics did not change).
1775
1776- Bug #1456209: In some obscure cases it was possible for a class with a
1777 custom ``__eq__()`` method to confuse dict internals when class instances
1778 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1779 No, you don't have any code that did this ;-)

1782-----------------
1783
Trent Mick960a3f82006-06-28 20:30:41 +00001784- Bug #1295808: expat symbols should be namespaced in pyexpat
1785
1786- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1787
Brett Cannon6ee7d012006-06-08 16:23:04 +00001788- Change binascii.hexlify to accept a read-only buffer instead of only a char
1789 buffer and actually follow its documentation.
1790
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001791- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1792
Nick Coghlanc649ec52006-05-29 12:43:05 +00001793- Patch #1478788 (modified version): The functional extension module has
1794 been renamed to _functools and a functools Python wrapper module added.
1795 This provides a home for additional function related utilities that are
1796 not specifically about functional programming. See PEP 309.
1797
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001798- Patch #1493701: performance enhancements for struct module.
1799
Georg Brandl378d5922006-05-17 14:26:50 +00001800- Patch #1490224: time.altzone is now set correctly on Cygwin.
1801
Georg Brandl8d3342b2006-05-16 07:38:27 +00001802- Patch #1435422: zlib's compress and decompress objects now have a
1803 copy() method.
1804
Andrew MacIntyre92913322006-06-13 15:04:24 +00001805- Patch #1454481: thread stack size is now tunable at runtime for thread
1806 enabled builds on Windows and systems with Posix threads support.
1807
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001808- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1809 (up to the system limit of 32K characters).
1810
1811- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1812 As a result, these functions now raise WindowsError instead of OSError.
1813
Tim Peters7a822da2006-05-25 21:50:17 +00001814- ``time.clock()`` on Win64 should use the high-performance Windows
1815 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1816 Windows platforms).
1817
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001818- Calling Tk_Init twice is refused if the first call failed as that
1819 may deadlock.
1820
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001821- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1822 accept it without potentially using an uninitialized pointer.
1823
1824- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1825 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1826 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001827
Gregory P. Smith372b5832006-06-05 18:48:21 +00001828- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001829 [pybsddb project SF patch number 1466734]
1830
Gregory P. Smith372b5832006-06-05 18:48:21 +00001831- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1832 parameter is supplied. [SF pybsddb bug #1477863]
1833
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001834- bsddb: the __len__ method of a DB object has been fixed to return correct
1835 results. It could previously incorrectly return 0 in some cases.
1836 Fixes SF bug 1493322 (pybsddb bug 1184012).
1837
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001838- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1839 aborts the db transaction safely when a modifier callback fails.
1840 Fixes SF python patch/bug #1408584.
1841
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001842- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001843 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001844 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1845 database calls that would previously deadlock. [SF python bug #775414]
1846
Vinay Sajip28e57612006-07-01 10:45:20 +00001847- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001848
Walter Dörwald4994d952006-06-19 08:07:50 +00001849- Patch #1506645: add Python wrappers for the curses functions
1850 is_term_resized, resize_term and resizeterm.

1862
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001863- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1864
Martin v. Löwis337487e2006-06-17 09:15:14 +00001865- Patch #763580: Add name and value arguments to Tkinter variable
1866 classes.
1867
Georg Brandl83cc0d02006-06-14 08:50:03 +00001868- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1869 mime.types file for determining MIME types.
1870
Georg Brandl2605ca82006-06-14 06:08:31 +00001871- Bug #1339007: Shelf objects now don't raise an exception in their
1872 __del__ method when initialization failed.
1873
Martin v. Löwisd8251432006-06-14 05:21:04 +00001874- Patch #1455898: The MBCS codec now supports the incremental mode for
1875 double-byte encodings.
1876
Tim Peters43898b42006-06-14 04:09:25 +00001877- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1878 guarantee that adjacent triples in the return list always describe
1879 non-adjacent blocks. Previously, a pair of matching blocks could end
1880 up being described by multiple adjacent triples that formed a partition
1881 of the matching pair.
1882
Greg Ward0e0c9f42006-06-11 16:24:11 +00001883- Bug #1498146: fix optparse to handle Unicode strings in option help,
1884 description, and epilog.
1885
Greg Wardd1c797e2006-06-11 14:42:41 +00001886- Bug #1366250: minor optparse documentation error.
1887
Greg Ward7f547402006-06-11 00:40:49 +00001888- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1889 clarify docs.
1890
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001891- The wsgiref package has been added to the standard library.
1892
Nick Coghlan676725d2006-06-08 13:54:49 +00001893- The functions update_wrapper() and wraps() have been added to the functools
1894 module. These make it easier to copy relevant metadata from the original
1895 function when writing wrapper functions.
1896
Tim Petersd6a9eef2006-06-05 01:48:21 +00001897- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1898 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001899
Martin v. Löwis3f767792006-06-04 19:36:28 +00001900- Patch #1359618: Speed up charmap encoder by using a trie structure
1901 for lookup.
1902
Tim Petersd609b1a2006-06-02 23:22:51 +00001903- The functions in the ``pprint`` module now sort dictionaries by key
1904 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1905 if and only if its display required more than one line, although that
1906 wasn't documented. The new behavior increases predictability; e.g.,
1907 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1908
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001909- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1910 (thanks for J. J. Lee).
1911
Georg Brandl2b330372006-05-28 20:23:12 +00001912- Patch #1496206: improve urllib2 handling of passwords with respect to
1913 default HTTP and HTTPS ports.
1914
George Yoshidaf3c65de2006-05-28 16:39:09 +00001915- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1916
Bob Ippolito7298f272006-05-23 18:43:47 +00001917- Patch #1281707: speed up gzip.readline.
1918
Georg Brandlb89316f2006-05-17 15:51:16 +00001919- Patch #1180296: Two new functions were added to the locale module:
1920 format_string() to get the effect of "format % items" but locale-aware,
1921 and currency() to format a monetary number with currency sign.
1922
Georg Brandle3a25832006-05-17 14:56:04 +00001923- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1924 and several features added, such as speed and geometry control.
1925
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001926- Patch #1488881: add support for external file objects in bz2 compressed
1927 tarfiles.
1928
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001929- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1930 stdout arguments, making it possible to redirect input and output
1931 for remote debugging.
1932
1933- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1934 a couple of issues, notably handling of long file names using the
1935 GNU LONGNAME extension.
1936
1937- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1938 new flag when ``name`` is already the name of an option flag.
1939
1940- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1941 package.
1942
1943- Patch #1472854: make the rlcompleter.Completer class usable on non-
1944 UNIX platforms.
1945
1946- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1947
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001948- Bug #1472827: correctly escape newlines and tabs in attribute values in

1985-----------------
1986
Thomas Heller1b046642006-04-18 18:51:06 +00001987- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1988 by converting these apis from macros into exported functions again:
1989
1990 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1991 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1992 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

1994 PyRun_String Py_CompileString
1995
Martin v. Löwis45294a92006-04-18 06:24:08 +00001996- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1997
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001998- All uses of PyStructSequence_InitType have been changed to initialize
1999 the type objects only once, even if the interpreter is initialized
2000 multiple times.
2001
Neal Norwitz61546162006-04-14 05:20:28 +00002002- Bug #1454485, array.array('u') could crash the interpreter. This was
2003 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2004 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2005
2006- Py_UNICODE is unsigned. It was always documented as unsigned, but
2007 due to a bug had a signed value in previous versions.
2008
Tim Peters3a5e8b12006-04-11 01:44:07 +00002009- Patch #837242: ``id()`` of any Python object always gives a positive
2010 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2011 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002012 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002013 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002014
Tim Peters3a5e8b12006-04-11 01:44:07 +00002015 def __hash__(self):
2016 return id(self) # WRONG
2017
2018 because a hash result must be a (short) Python int but it was always
2019 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002020 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002021 was always usable as a hash value before this patch. That's no longer
2022 necessarily so.
2023
2024- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002025 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002026 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002027 #1454844)
2028
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002029- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2030 involving generators that have paused outside of any ``try`` or ``with``
2031 blocks. (In 2.5a1, a paused generator that was part of a reference
2032 cycle could not be garbage collected, regardless of whether it was
2033 paused in a ``try`` or ``with`` block.)

Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00002038- Patch #1191065: Fix preprocessor problems on systems where recvfrom
2039 is a macro.

Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002041- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2042 fails with an error condition.
2043
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002044- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2045
2046- Bug #1117761: bsddb.*open() no longer raises an exception when using
2047 the cachesize parameter.
2048
2049- Bug #1149413: bsddb.*open() no longer raises an exception when using
2050 a temporary db (file=None) with the 'n' flag to truncate on open.
2051
2052- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2053 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002054
Armin Rigoa9017c32006-04-19 11:50:27 +00002055- Patch #1062014: AF_UNIX sockets under Linux have a special
2056 abstract namespace that is now fully supported.

Peter Astrand7d1d4362006-07-14 14:04:45 +00002061- Bug #1223937: subprocess.CalledProcessError reports the exit status
2062 of the process using the returncode attribute, instead of
2063 abusing errno.
2064
Tim Peters711bf302006-04-25 03:31:36 +00002065- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2066 a doctest to be skipped (the code is not run, and the expected output
2067 or exception is ignored).
2068
Nick Coghlanda2268f2006-04-24 04:37:15 +00002069- Fixed contextlib.nested to cope with exceptions being raised and
2070 caught inside exit handlers.
2071
Greg Wardab05edc2006-04-23 03:47:58 +00002072- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2073 hex, octal, or binary; add ``append_const`` action; keep going if
2074 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2075 added ``epilog`` for better help generation).
2076
Tim Peters21fbd572006-04-21 21:18:10 +00002077- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2078 called from a thread spawned as a side effect of importing a module.
2079
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002080- The pydoc module now supports documenting packages contained in
2081 .zip or .egg files.
2082
2083- The pkgutil module now has several new utility functions, such
2084 as ``walk_packages()`` to support working with packages that are either
2085 in the filesystem or zip files.
2086
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002087- The mailbox module can now modify and delete messages from
2088 mailboxes, in addition to simply reading them. Thanks to Gregory
2089 K. Johnson for writing the code, and to the 2005 Google Summer of
2090 Code for funding his work.

Skip Montanaro262fb922006-04-21 02:31:07 +00002115- The pstats.Stats class accepts an optional stream keyword argument to
2116 direct output to an alternate file-like object.
2117

2119-----
2120
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002121- The Makefile now has a reindent target, which runs reindent.py on
2122 the library.
2123
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002124- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis0f48d982006-04-14 14:34:26 +00002128- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2129 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002130 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002131 CXX from --with-cxx-main, see description in README.
2132
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002133- Patch #1429775: Link extension modules with the shared libpython.

2142-----
2143
Nick Coghlanda2268f2006-04-24 04:37:15 +00002144- test_contextlib now checks contextlib.nested can cope with exceptions
2145 being raised and caught inside exit handlers.
2146
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002147- test_cmd_line now checks operation of the -m and -c command switches
2148
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002149- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2150 it separately and by hand. It also wasn't cleaning up its changes to
2151 the current Decimal context.
2152
Thomas Woutersabd08882006-04-26 15:53:30 +00002153- regrtest.py now has a -M option to run tests that test the new limits of
2154 containers, on 64-bit architectures. Running these tests is only sensible
2155 on 64-bit machines with more than two gigabytes of memory. The argument
2156 passed is the maximum amount of memory for the tests to use.

2165-------------
2166
Tim Petersb06d28c2006-05-12 01:57:59 +00002167- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2168
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002169- PEP 343: Added Context Types section to the library reference
2170 and attempted to bring other PEP 343 related documentation into
2171 line with the implementation and/or python-dev discussions.
2172
Tim Peters8dc73d22006-04-24 02:03:16 +00002173- Bug #1337990: clarified that ``doctest`` does not support examples
2174 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002177What's New in Python 2.5 alpha 1?
2178=================================
2179
Anthony Baxterebed3f62006-04-03 15:03:44 +00002180*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002181
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002182Core and builtins
2183-----------------
2184
Nick Coghlan43832302006-04-23 17:04:07 +00002185- PEP 338: -m command line switch now delegates to runpy.run_module
2186 allowing it to support modules in packages and zipfiles
2187
Martin v. Löwisc661b882006-04-20 04:54:23 +00002188- On Windows, .DLL is not an accepted file name extension for
2189 extension modules anymore; extensions are only found if they
2190 end in .PYD.
2191
Martin v. Löwisea62d252006-04-03 10:56:49 +00002192- Bug #1421664: sys.stderr.encoding is now set to the same value as
2193 sys.stdout.encoding.
2194
Neal Norwitz92e212f2006-04-03 04:48:37 +00002195- __import__ accepts keyword arguments.
2196
Georg Brandlccadf842006-03-31 18:54:53 +00002197- Patch #1460496: round() now accepts keyword arguments.
2198
Anthony Baxter262c00a2006-03-30 10:53:17 +00002199- Fixed bug #1459029 - unicode reprs were double-escaped.
2200
Hye-Shik Changd478f342006-03-23 12:32:36 +00002201- Patch #1396919: The system scope threads are reenabled on FreeBSD
2202 5.4 and later versions.
2203
Neal Norwitze98ccf62006-03-23 05:39:47 +00002204- Bug #1115379: Compiling a Unicode string with an encoding declaration
2205 now gives a SyntaxError.
2206
Georg Brandlabd1ff82006-03-18 07:59:59 +00002207- Previously, Python code had no easy way to access the contents of a
2208 cell object. Now, a ``cell_contents`` attribute has been added
2209 (closes patch #1170323).
2210
Tim Peterscf79aac2006-03-16 01:14:46 +00002211- Patch #1123430: Python's small-object allocator now returns an arena to
2212 the system ``free()`` when all memory within an arena becomes unused
2213 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2214 freed. Some applications will see a drop in virtual memory size now,
2215 especially long-running applications that, from time to time, temporarily
2216 use a large number of small objects. Note that when Python returns an
2217 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002218 platform C library will in turn return that memory to the operating system.
2219 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002220 appears to be effective at least on Microsoft C and gcc-based systems.
2221 Thanks to Evan Jones for hard work and patience.
2222
Georg Brandl533ff6f2006-03-08 18:09:27 +00002223- Patch #1434038: property() now uses the getter's docstring if there is
2224 no "doc" argument given. This makes it possible to legitimately use
2225 property() as a decorator to produce a read-only property.
2226
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002227- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2228 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2229 of requiring an int or long in slicing and a few other contexts, enabling
2230 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2231
Neal Norwitz995acdf2006-03-07 05:01:00 +00002232- Fixed various bugs reported by Coverity's Prevent tool.
2233
Brett Cannonbf364092006-03-01 04:25:17 +00002234- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2235 new exception base class, BaseException, which has a new message attribute.
2236 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2237 Raising a string exception now raises a DeprecationWarning.
2238
Thomas Woutersfb609f42006-02-28 16:37:25 +00002239- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2240 explicitly relative, using 'from .module import name' to mean 'from the same
2241 package as this module is in. Imports without dots still default to the
2242 old relative-then-absolute, unless 'from __future__ import
2243 absolute_import' is used.
2244
Brett Cannona7446e32006-02-27 23:39:10 +00002245- Properly check if 'warnings' raises an exception (usually when a filter set
2246 to "error" is triggered) when raising a warning for raising string
2247 exceptions.
2248
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002249- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002250 The name was removed from Include/code.h.
2251
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002252- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002253
Guido van Rossum1968ad32006-02-25 22:38:04 +00002254- Patch 1433928:
2255 - The copy module now "copies" function objects (as atomic objects).
2256 - dict.__getitem__ now looks for a __missing__ hook before raising
2257 KeyError.
2258
Tim Peters84ef21c2006-02-28 20:39:06 +00002259- PEP 343: with statement implemented. Needs ``from __future__ import
2260 with_statement``. Use of 'with' as a variable will generate a warning.
2261 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002262 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002263 The following objects have __context__ methods:
2264 - The built-in file type.
2265 - The thread.LockType type.
2266 - The following types defined by the threading module:
2267 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2268 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002269
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002270- Fix the encodings package codec search function to only search
2271 inside its own package. Fixes problem reported in patch #1433198.
2272
2273 Note: Codec packages should implement and register their own
2274 codec search function. PEP 100 has the details.
2275
Tim Peters9ea89d22006-06-04 03:26:02 +00002276- PEP 353: Using ``Py_ssize_t`` as the index type.
2277
2278- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2279 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2280 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2281 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2282 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002283
Neal Norwitzfc76d632006-01-10 06:03:13 +00002284- Patch #1400181, fix unicode string formatting to not use the locale.
2285 This is how string objects work. u'%f' could use , instead of .
2286 for the decimal point. Now both strings and unicode always use periods.
2287
Neal Norwitz671b9e32006-01-09 07:07:12 +00002288- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2289 configure would break checking curses.h.
2290
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002291- Bug #959576: The pwd module is now builtin. This allows Python to be
2292 built on UNIX platforms without $HOME set.
2293
Neal Norwitzc10978f2005-12-19 06:07:16 +00002294- Bug #1072182, fix some potential problems if characters are signed.
2295
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002296- Bug #889500, fix line number on SyntaxWarning for global declarations.
2297
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002298- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2299
Neal Norwitze7214a12005-12-18 05:03:17 +00002300- Support for converting hex strings to floats no longer works.
2301 This was not portable. float('0x3') now raises a ValueError.
2302
Barry Warsaw2a38a862005-12-18 01:27:35 +00002303- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002304 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002305 is now displayed in interactive prompt banner.
2306
Georg Brandlfa166682005-12-17 21:45:17 +00002307- Implementation of PEP 341 - Unification of try/except and try/finally.
2308 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002309 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002310
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002311- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2312 now encodes backslash correctly.
2313
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002314- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2315
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002316- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002317 and long longs.
2318
Neal Norwitz67715f02005-11-09 06:59:35 +00002319- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002320 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002321 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002322
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002323- Replaced most Unicode charmap codecs with new ones using the
2324 new Unicode translate string feature in the builtin charmap
2325 codec; the codecs were created from the mapping tables available
2326 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2327 encodings now include a mapping for the Apple logo)
2328
Tim Peterse3547fd2005-12-16 23:13:57 +00002329- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002330
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002331- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002332
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002333- A new AST parser implementation was completed. The abstract
2334 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002335 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002336
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002337- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002338 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2339
Neal Norwitz708e51a2005-10-03 04:48:15 +00002340- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2341
Neal Norwitz11bd1192005-10-03 00:54:56 +00002342- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2343 Provide a warning when a directory is passed on the command line.
2344
Neal Norwitz40d37812005-10-02 01:48:49 +00002345- Fix segfault with invalid coding.
2346
2347- SF bug #772896: unknown encoding results in MemoryError.
2348
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002349- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002350 supported a __len__() method which evaluated to False when the iterator
2351 was empty.
2352
Guido van Rossum630db602005-09-20 18:49:54 +00002353- On 64-bit platforms, when __len__() returns a value that cannot be
2354 represented as a C int, raise OverflowError.
2355
Skip Montanarof8948ca2005-09-19 03:54:46 +00002356- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002357 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002358
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002359- SF bug #893549: parsing keyword arguments was broken with a few format
2360 codes.
2361
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002362- Changes donated by Elemental Security to make it work on AIX 5.3
2363 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2364 bug #105470: test_pwd fails on 64bit system (Opteron).
2365
Guido van Rossum539c6622005-09-14 17:49:54 +00002366- Changes donated by Elemental Security to make it work on HP-UX 11 on
2367 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2368
Georg Brandl4550b8d2005-08-26 06:43:52 +00002369- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002370 (fixes bug #1119418).
2371
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002372- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2373
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002374- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2375 exceptions that cause a function to exit.
2376
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002377- The implementation of set() and frozenset() was revised to use its
2378 own internal data structure. Memory consumption is reduced by 1/3
2379 and there are modest speed-ups as well. The API is unchanged.
2380
Tim Petersde7990b2005-07-17 23:45:23 +00002381- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2382
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002383- SF bug #1229429: PyObject_CallMethod failed to decrement some
2384 reference counts in some error exit cases.
2385
Tim Petersecc6e6a2005-07-10 22:30:55 +00002386- SF bug #1185883: Python's small-object memory allocator took over
2387 a block managed by the platform C library whenever a realloc specified
2388 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002389 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002390 portable way to copy data from the C-managed block into Python's
2391 small-object space without risking a memory fault. Python's small-object
2392 realloc now leaves such blocks under the control of the platform C
2393 realloc.
2394
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002395- SF bug #1232517: An overflow error was not detected properly when
2396 attempting to convert a large float to an int in os.utime().
2397
Raymond Hettinger3296e692005-06-29 23:29:56 +00002398- SF bug #1224347: hex longs now print with lowercase letters just
2399 like their int counterparts.
2400
Michael W. Hudson188d4362005-06-20 16:52:57 +00002401- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2402 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2403 interpreter states; back out that fix and do a better job (see
2404 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2405 for a longer write-up of the problem).
2406
Michael W. Hudsondf888462005-06-03 14:41:55 +00002407- SF patch #1180995: marshal now uses a binary format by default when
2408 serializing floats.
2409
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002410- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2411 the routines that promise to produce IEEE 754 binary representations
2412 of floats now simply copy bytes around.
2413
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002414- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2415 278.
2416
Brett Cannonc3647ac2005-04-26 03:45:26 +00002417- patch #1109424: int, long, float, complex, and unicode now check for the
2418 proper magic slot for type conversions when subclassed. Previously the
2419 magic slot was ignored during conversion. Semantics now match the way
2420 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002421 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002422 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002423 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002424
Barry Warsawc8d907c2005-04-19 23:43:40 +00002425- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2426 NULL, now raise an AttributeError when attempting to set or delete the
2427 attribute. Previously a TypeError was raised, but this was inconsistent
2428 with the equivalent pure-Python implementation.
2429
Michael W. Hudson774479c2005-04-18 08:46:17 +00002430- It is now safe to call PyGILState_Release() before
2431 PyEval_InitThreads() (note that if there is reason to believe there
2432 are multiple threads around you still must call PyEval_InitThreads()
2433 before using the Python API; this fix is for extension modules that
2434 have no way of knowing if Python is multi-threaded yet).
2435
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002436- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2437 disabled caused a crash.
2438
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002439- Bug #1165306: instancemethod_new allowed the creation of a method
2440 with im_class == im_self == NULL, which caused a crash when called.
2441
Tim Petersecc6e6a2005-07-10 22:30:55 +00002442- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002443 fixes the crash seen in bug #1165761
2444
Raymond Hettinger96229b12005-03-11 06:49:40 +00002445- Added two new builtins, any() and all().
2446
Brett Cannon409d8f22005-03-05 06:47:57 +00002447- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002448 (e.g., ``class C(): pass`` is no longer a syntax error).
2449 Patch #1176012 added support to the 'parser' module and 'compiler' package
2450 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002451
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002452- Patch #1115086: Support PY_LONGLONG in structmember.
2453
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002454- Bug #1155938: new style classes did not check that __init__() was
2455 returning None.
2456
Tim Petersecc6e6a2005-07-10 22:30:55 +00002457- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002458 ('\') with a specific error message.
2459
Martin v. Löwisff232d72005-03-03 09:24:38 +00002460- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2461
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002462- Bug #1124295: the __name__ attribute of file objects was
2463 inadvertently made inaccessible in restricted mode.
2464
Tim Petersecc6e6a2005-07-10 22:30:55 +00002465- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002466 an ferror() call.
2467
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002468- min() and max() now support key= arguments with the same meaning as in
2469 list.sort().
2470
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002471- The peephole optimizer now performs simple constant folding in expressions:
2472 (2+3) --> (5).
2473
Raymond Hettingera422c342005-01-11 03:03:27 +00002474- set and frozenset objects can now be marshalled. SF #1098985.
2475
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002476- Bug #1077106: Poor argument checking could cause memory corruption
2477 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002478
Jeremy Hyltonab630502005-02-04 18:44:06 +00002479- The parser did not complain about future statements in illegal
2480 positions. It once again reports a syntax error if a future
2481 statement occurs after anything other than a doc string.
2482
Neil Schemenauercf52c072005-08-12 17:34:58 +00002483- Change the %s format specifier for str objects so that it returns a
2484 unicode instance if the argument is not an instance of basestring and
2485 calling __str__ on the argument returns a unicode instance.
2486
Tim Petersf4e69282006-02-27 17:15:31 +00002487- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2488 current thread state when the auto-GIL-state machinery knows about
2489 it (since the thread state is being deleted, continuing to remember it
2490 can't help, but can hurt if another thread happens to get created with
2491 the same thread id).
2492
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002493Extension Modules
2494-----------------
2495

Tim Petersc9d78aa2006-03-26 23:27:58 +00002508 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002509 util, whatsound, whrandom, zmod
2510
2511- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2512
2513- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002514 is deprecated. The undocumented re.engine variable no longer exists.
2515
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002516- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2517 SS2 (single-shift 2) escape sequences correctly.
2518
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002519- The unicodedata module was updated to the 4.1 version of the Unicode
2520 database. The 3.2 version is still available as unicodedata.db_3_2_0
2521 for applications that require this specific version (such as IDNA).
2522
Neal Norwitzb62c4332006-03-04 18:35:47 +00002523- The timing module is no longer built by default. It was deprecated
2524 in PEP 4 in Python 2.0 or earlier.
2525
Guido van Rossum1968ad32006-02-25 22:38:04 +00002526- Patch 1433928: Added a new type, defaultdict, to the collections module.
2527 This uses the new __missing__ hook behavior added to dict (see above).
2528
Georg Brandldbd83392006-02-20 09:42:33 +00002529- Bug #854823: socketmodule now builds on Sun platforms even when
2530 INET_ADDRSTRLEN is not defined.
2531
Georg Brandlf4f44152006-02-18 22:29:33 +00002532- Patch #1393157: os.startfile() now has an optional argument to specify
2533 a "command verb" to invoke on the file.
2534
Neal Norwitz082b2df2006-02-07 07:04:46 +00002535- Bug #876637, prevent stack corruption when socket descriptor
2536 is larger than FD_SETSIZE.
2537
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002538- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2539 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2540 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
2541
Martin v. Löwis57a34e82006-02-04 19:12:37 +00002542- Patch #1422385: The nis module now supports access to domains other
2543 than the system default domain.
2544
Martin v. Löwis14694662006-02-03 12:54:16 +00002545- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2546 are reported, the limit on path name lengths is removed, and stat reports
2547 WindowsError now (instead of OSError).
2548
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002549- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2624 the request code argument, which results in more C-like behaviour
2625 for large or negative values.
2626
Tim Petersecc6e6a2005-07-10 22:30:55 +00002627- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2642
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00002643- operator.itemgetter() and operator.attrgetter() now support retrieving

2668 args tuple returned by __reduce__().
2669
Raymond Hettingerb2594052004-12-05 09:25:51 +00002670- itertools.islice() now accepts None for the start and step arguments.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002683- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2684 been renamed to have only a single underscore prefix. This was done to
2685 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002686
Nick Coghlan43832302006-04-23 17:04:07 +00002687- PEP 338: new module runpy defines a run_module function to support
2688 executing modules which provide access to source code or a code object
2689 via the PEP 302 import mechanisms.
2690
Anthony Baxter93f5b932006-04-03 08:05:07 +00002691- The email module's parsedate_tz function now sets the daylight savings

2699 in attribute values.
2700
Anthony Baxterc51ee692006-04-01 00:57:31 +00002701- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002702 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002703 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002704 module will not be built.
2705
Tim Petersc17976e2006-04-01 00:26:53 +00002706- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2707 aren't officially supported here, and trying to use them will probably
2708 raise an exception some day. But dicts have been allowed, and "mostly
2709 worked", so support for them won't go away without warning.
2710
Georg Brandl338ef7d2006-03-31 18:42:16 +00002711- Bug #1445068: getpass.getpass() can now be given an explicit stream
2712 argument to specify where to write the prompt.
2713
Georg Brandl22ec80b2006-03-31 18:25:44 +00002714- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2721
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002722- Queue.Queue objects now support .task_done() and .join() methods
2723 to make it easier to monitor when daemon threads have completed
2724 processing all enqueued tasks. Patch #1455676.
2725
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002726- popen2.Popen objects now preserve the command in a .cmd attribute.

2729
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002730- email 4.0 package now integrated. This is largely the same as the email 3.0
2731 package that was included in Python 2.3, except that PEP 8 module names are
2732 now used (e.g. mail.message instead of email.Message). The MIME classes
2733 have been moved to a subpackage (e.g. email.mime.text instead of
2734 email.MIMEText). The old names are still supported for now. Several
2735 deprecated Message methods have been removed and lots of bugs have been
2736 fixed. More details can be found in the email package documentation.
2737
Walter Dörwald40108c92006-03-27 08:15:44 +00002738- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2739 (a subclass of tuple) that provides incremental decoders and encoders
2740 (a way to use stateful codecs without the stream API). Python functions
2741 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2742 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2743 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002744
Walter Dörwald067db482006-03-15 22:17:27 +00002745- Patch #1359365: Calling next() on a closed StringIO.String object raises
2746 a ValueError instead of a StopIteration now (like file and cString.String do).
2747 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2748 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002749
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002750- A regrtest option -w was added to re-run failed tests in verbose mode.

2760
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002761- PEP 343: new module contextlib.py defines decorator @contextmanager
2762 and helpful context managers nested() and closing().
2763
Martin v. Löwis415ed932006-02-27 19:56:30 +00002764- The compiler package now supports future imports after the module docstring.
2765

2767 not allowed by the specs.
2768
Georg Brandlc98eeed2006-02-19 14:57:47 +00002769- Patch #1215184: FileInput now can be given an opening hook which can

Martin v. Löwis3e865952006-01-24 15:51:21 +00002798 specifications, raises IOErrors when proxies for unsupported protocols
2799 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002822 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2823 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2824 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2825 Ronald L. Rivest offered this advice for Python:
2826
2827 "The consensus of researchers in this area (at least as
2828 expressed at the NIST Hash Function Workshop 10/31/05),
2829 is that SHA-256 is a good choice for the time being, but
2830 that research should continue, and other alternatives may
2831 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002832
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002833- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandlb9256022005-08-24 18:46:39 +00002879- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
2880 ContentTooShortException, when the actually downloaded size does not
2881 match the Content-Length header.
2882
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +00002883- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.

2886 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002887 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002888

2908
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002909- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2910 to W3C name (404 -> 'Not Found'). RFE #1216944.
2911
Georg Brandl9e43acf2005-07-04 17:16:07 +00002912- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2913 as this can cause problems with apps closing all file descriptors.

Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002925- The tokenize module now detects and reports indentation errors.
2926 Bug #1224621.
2927
Raymond Hettinger68c04532005-06-10 11:05:19 +00002928- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002929 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002930 the generate_tokens() function now accepts a callable argument that
2931 terminates by raising StopIteration.
2932
Georg Brandl9166e1a2005-06-04 09:20:03 +00002933- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2940 to True, applications shouldn't have to fiddle with the DateTime wrapper
2941 class at all.
2942
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002943- distutils.commands.upload was added to support uploading distribution
2944 files to PyPI.
2945
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002946- distutils.commands.register now encodes the data as UTF-8 before posting
2947 them to PyPI.
2948
Raymond Hettinger267b8682005-03-27 10:47:39 +00002949- decimal operator and comparison methods now return NotImplemented
2950 instead of raising a TypeError when interacting with other types. This
2951 allows other classes to implement __radd__ style methods and have them
2952 work as expected.
2953
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002954- Bug #1163325: Decimal infinities failed to hash. Attempting to
2955 hash a NaN raised an InvalidOperation instead of a TypeError.
2956
Tim Petersecc6e6a2005-07-10 22:30:55 +00002957- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2991
Guido van Rossumd0641422005-02-03 15:01:24 +00002992- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2993 disables recursive traversal through instance attributes, which can
2994 be exploited in various ways.
2995
Tim Peterse3547fd2005-12-16 23:13:57 +00002996- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002997 flags on the HTTP listening socket.
2998
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002999- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3000 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3001
Fred Drakefbdeaad2006-07-29 16:56:15 +00003002- Patches #893642, #1039083: add allow_none, encoding arguments to
3003 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003004
Martin v. Löwis1d11de62005-01-29 13:29:23 +00003005- Bug #1110478: Revert os.environ.update to do putenv again.
3006
Thomas Hellerd6c6e222005-01-20 19:20:16 +00003007- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3008
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003009- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3010
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003011- Enhancements to the csv module:
3012
3013 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003014 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003015 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003016 + Dialect parameter parsing has been re-implemented to improve error
3017 reporting.
3018 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3019 dictates.
3020 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003021 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003022 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003023 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3024 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003025 + reader now allows \r characters to be quoted (previously it only allowed
3026 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003027 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003028 + Dialect classes passed to the module are no longer instantiated by
3029 the module before being parsed (the former validation scheme required
3030 this, but the mechanism was unreliable).
3031 + The dialect registry now contains instances of the internal
3032 C-coded dialect type, rather than references to python objects.
3033 + the internal c-coded dialect type is now immutable.
3034 + register_dialect now accepts the same keyword dialect specifications
3035 as the reader and writer, allowing the user to register dialects
3036 without first creating a dialect class.
3037 + a configurable limit to the size of parsed fields has been added -
3038 previously, an unmatched quote character could result in the entire
3039 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003040 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003041 the parser field size limit (returning the former limit). The initial
3042 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003043 + A line_num attribute has been added to the reader object, which tracks
3044 the number of lines read from the source iterator. This is not
3045 the same as the number of records returned, as records can span
3046 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003047 + reader and writer objects were not being registered with the cyclic-GC.
3048 This has been fixed.
3049
Brett Cannone6539c42005-01-08 02:43:53 +00003050- _DummyThread objects in the threading module now delete self.__block that is
3051 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3052 lock primitives tend to be limited in number and thus should not be wasted on
3053 a _DummyThread object. Fixes bug #1089632.
3054
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003055- The imghdr module now detects Exif files.
3056
Raymond Hettinger6065d322004-12-20 23:51:53 +00003057- StringIO.truncate() now correctly adjusts the size attribute.
3058 (Bug #951915).
3059
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003060- locale.py now uses an updated locale alias table (built using
3061 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3062 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003063 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003064
Raymond Hettinger3557f422004-12-07 12:02:02 +00003065- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3066
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003067- the pickle module no longer accepts the deprecated None option in the
3068 args tuple returned by __reduce__().
3069
Brett Cannon84667c02004-12-07 03:25:18 +00003070- optparse now optionally imports gettext. This allows its use in setup.py.
3071
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003072- the pickle module no longer uses the deprecated bin parameter.
3073
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003074- the shelve module no longer uses the deprecated binary parameter.
3075
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003076- the pstats module no longer uses the deprecated ignore() method.
3077
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003078- the filecmp module no longer uses the deprecated use_statcache argument.
3079
Raymond Hettinger664347b2004-12-04 21:21:53 +00003080- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3081 extended or overridden by subclasses. Formerly, the subclassed method would
3082 be ignored by the rest of the module. (Bug #1078905).
3083
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003084- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003085 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003086
Walter Dörwald36733692004-12-22 12:50:50 +00003087- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3088 once when a size argument is given. This prevents a buffer overflow in the
3089 tokenizer with very long source lines.
3090
Barry Warsaw538561e2006-01-01 21:48:54 +00003091- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3092 immediately after creating the object, without any intervening
3093 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003094
Skip Montanaro05885812005-01-16 20:48:27 +00003095- The reconvert.quote function can now emit triple-quoted strings. The
3096 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003097
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003098- ``UserString.MutableString`` now supports negative indices in
3099 ``__setitem__`` and ``__delitem__``
3100
Greg Ward40407942005-03-05 02:53:17 +00003101- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3102 correctly.
3103
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003104- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3105 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3106 character even if the user has passed a size parameter to get a proper
3107 line ending. Remove the special handling of a "\r\n" that has been split
3108 between two lines.
3109
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003110- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3111 about illegal code points. The codec now supports PEP 293 style error
3112 handlers.
3113
Walter Dörwald78a78b02005-09-01 12:04:29 +00003114- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003115 from the input stream, so that the output is a byte string in the correct
3116 encoding instead of a unicode string.

Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003118- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3119 considering it exactly like a '*'.
3120
Walter Dörwald007f8df2005-10-09 19:42:27 +00003121- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3122 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003123
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003124- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3125
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003126- Patch #1413711: Certain patterns of differences were making difflib
3127 touch the recursion limit.
3128
Walter Dörwald58917a62006-03-31 15:26:22 +00003129- Bug #947906: An object oriented interface has been added to the calendar
3130 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003131 called as a script (e.g. via ``python -mcalendar``). Localized month and
3132 weekday names can be ouput (even if an exotic encoding is used) using
3133 special classes that use unicode.

3142
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003143- Build support for Win64-AMD64 was added.
3144
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003145- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3146
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003147- Patch #881820: look for openpty and forkpty also in libbsd.
3148
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003149- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3150 The zlib module is now builtin on Windows.
3151
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003152- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3153
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003154- Bug #1189330: configure did not correctly determine the necessary
3155 value of LINKCC if python was built with GCC 4.0.
3156
Trent Mick8321b422005-07-26 02:29:21 +00003157- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3158 vulnerability in zlib 1.2.1 and 1.2.2.
3159
Brett Cannon08cd5982005-04-24 22:26:38 +00003160- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3161 flags that change binary compatibility. Changes were also made to
3162 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003163 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003164
Bob Ippolitoed233462005-03-29 13:47:59 +00003165- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3166 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3167 no longer exists). This configure patch makes things right.
3168
Martin v. Löwise2713be2005-03-08 15:03:08 +00003169- Bug #1158607: Build with --disable-unicode again.
3170
Brett Cannon46d96232005-02-16 00:07:19 +00003171- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3172 defined. Discovered as a result of not being able to build on OS X.
3173
Brett Cannon516592f2004-12-07 00:42:59 +00003174- setup.py now uses the directories specified in LDFLAGS using the -L option
3175 and in CPPFLAGS using the -I option for adding library and include
3176 directories, respectively, for compiling extension modules against. This has
3177 led to the core being compiled using the values in CPPFLAGS. It also removes
3178 the need for the special-casing of both DarwinPorts and Fink for darwin since
3179 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3180 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3181 Fink, ``-I/opt/local/include`` for DarwinPorts).
3182
Brett Cannon43802422005-02-10 20:48:03 +00003183- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3184 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3185 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3186 Closes bug #1096244. Thanks Gregory Bond.

3189-----
3190
Tim Petersc9d78aa2006-03-26 23:27:58 +00003191- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3192 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3193 is obtained via the ``PyObject_`` family, it must be released via the
3194 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3195 always been officially true, but when Python's small-object allocator was
3196 introduced, an attempt was made to cater to a few extension modules
3197 discovered at the time that obtained memory via ``PyObject_New`` but
3198 released it via ``PyMem_DEL``. It's years later, and if such code still
3199 exists it will fail now (probably with segfaults, but calling wrong
3200 low-level memory management functions can yield many symptoms).
3201
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003202- Added a C API for set and frozenset objects.
3203

3205
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003206- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3207 mapping argument now. This string is used as a mapping table. Byte values
3208 greater than the length of the string and 0xFFFE are treated as undefined
3209 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003216
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003217- Patch #1276356: New resource "urlfetch" is implemented. This enables
3218 even impatient people to run tests that require remote files.
