11
12Core and builtins
13-----------------
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000014
Georg Brandl45c33ce2008-08-11 09:13:26 +000015- Issue #3537: Fix an assertion failure when an empty but presized dict
16 object was stored in the freelist.
17
Neal Norwitz4f3be8a2008-07-31 17:08:14 +000018- Apply security patches from Apple.
19
Neal Norwitz83ac0142008-07-28 05:06:20 +000020- Issue #2620: Overflow checking when allocating or reallocating memory
21 was not always being done properly in some python types and extension
22 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
23 all been updated to perform better checks and places in the code that
24 would previously leak memory on the error path when such an allocation
25 failed have been fixed.
26
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +000027- Issue #2242: Fix a crash when decoding invalid utf-7 input on certain
28 Windows / Visual Studio versions.
29
Mark Dickinsonab396e02008-07-16 11:04:17 +000030- Issue #3360: Fix incorrect parsing of '020000000000.0', which
31 produced a ValueError instead of giving the correct float.
32
Amaury Forgeot d'Arcceda6a62008-07-01 20:52:56 +000033- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
34 set to a custom object whose write() method happens to install
35 another file in sys.stdout.
36
Amaury Forgeot d'Arcb15bdf72008-07-01 20:59:49 +000037- Issue #3088: Corrected a race condition in classes derived from
38 threading.local: the first member set by a thread could be saved in
39 another thread's dictionary.
40
Amaury Forgeot d'Arc3255e132008-06-16 19:22:42 +000041- Issue #3100: Corrected a crash on deallocation of a subclassed weakref which
42 holds the last (strong) reference to its referent.
43
Guido van Rossumaa975432008-04-10 22:43:58 +000044- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
45 having a self-referential tuple, which is possible from C code. Nor did
46 object's tp_str consider that a type's tp_str could do something that could
47 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
48 respectively, fixed the issues. (Backport of r58288 from trunk.)
49
Georg Brandld9f1da02008-03-29 01:50:46 +000050- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
51 cannot be executed.
52
Amaury Forgeot d'Arc8432d862008-03-28 20:45:42 +000053- The compilation of a class nested in another class used to leak one
54 reference on the outer class name.
55
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000056- Issue #1477: With narrow Unicode builds, the unicode escape sequence
57 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
58 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
59 UTF-16 surrogates are generated in this case, like normal unicode literals
60 and the 'unicode-escape' codec.
61
Neal Norwitzb3635f92008-03-18 04:17:36 +000062- Issue #2321: use pymalloc for unicode object string data to reduce
63 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +000064
Sean Reifscheider4af861c2008-03-20 17:39:31 +000065- Issue #2238: Some syntax errors in *args and **kwargs expressions could give
66 bogus error messages.
67
Gregory P. Smith14acde32008-04-09 23:41:13 +000068- Issue #2587: In the C API, PyString_FromStringAndSize() takes a signed size
69 parameter but was not verifying that it was greater than zero. Values
70 less than zero will now raise a SystemError and return NULL to indicate a
71 bug in the calling C code.
72
Gregory P. Smith9aa040d2008-06-02 00:07:25 +000073- Issue #2588, #2589: Fix potential integer underflow and overflow
74 conditions in the PyOS_vsnprintf C API function.
75

78-------
79
Thomas Heller275e2292008-08-19 17:17:37 +000080- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
81 api functions without holding the GIL, which could lead to a fatal
82 error when they failed.
83
Amaury Forgeot d'Arc22679b82008-08-18 19:33:42 +000084- Issue #2234: distutils failed for some versions of the cygwin compiler. The
85 version reported by these tools does not necessarily follow the python
86 version numbering scheme, so the module is less strict when parsing it.
87
Hirokazu Yamamoto1d63a452008-08-17 09:49:10 +000088- Issue #2222: Fixed reference leak when occured os.rename()

92
Robert Schuppenies78813dc2008-08-10 11:19:25 +000093- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
94 menu entries were not deleted.
95
Martin v. Löwisc7af7f32008-08-02 07:21:06 +000096- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
97
Brett Cannonff931572008-07-13 01:20:19 +000098- Issue #3339: dummy_thread.acquire() could return None which is not a valid
99 return value.
100
Raymond Hettinger75ee9eb2008-06-16 01:49:18 +0000101- Issue #3116 and #1792: Fix quadratic behavior in marshal.dumps().
102
Thomas Hellerf3bb2832008-04-25 19:55:19 +0000103- Issue #2682: ctypes callback functions no longer contain a cyclic
104 reference to themselves.
105
Amaury Forgeot d'Arc8d904c32008-04-22 21:17:18 +0000106- Issue #2670: Fix a failure in urllib2.build_opener(), when passed two
107 handlers that derive the same default base class.
108
Amaury Forgeot d'Arc198e3532008-03-27 23:41:59 +0000109- Issue #2495: tokenize.untokenize now inserts a space between two consecutive

111 incorrect python code.
112
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +0000113- Issue #2482: Make sure that the coefficient of a Decimal is always
114 stored as a str instance, not as a unicode instance. This ensures
115 that str(Decimal) is always an instance of str. This fixes a
116 regression from Python 2.5.1 to Python 2.5.2.
117
Mark Dickinson26c25d92008-03-25 14:35:25 +0000118- Issue #2478: fix failure of decimal.Decimal(0).sqrt()

129 root directory, and also exclude .hg, .git, .bzr, and _darcs.
130
Andrew M. Kuchling37d4f7b2008-02-23 19:06:54 +0000131- Bug #1389051: imaplib causes excessive memory fragmentation when reading
132 large messages.
133
Andrew M. Kuchling664553a2008-02-23 19:30:59 +0000134- Bug #1389051, 1092502: fix excessively large memory allocations when
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000135 calling .read() on a socket object wrapped with makefile().

141 stdout and stderr fds rather than leaving them open until the
142 instance is destroyed.
143
Gregory P. Smithf8f30fa2008-07-06 04:04:07 +0000144- Issue #2632: Prevent socket.read(bignumber) from over allocating memory
145 in the common case when the data is returned from the underlying socket
146 in increments much smaller than bignumber.
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +0000147
Gregory P. Smithb4bc9b92008-08-04 00:15:54 +0000148- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
149 argument in python 2.5, this broke code that subclassed Popen to include its
150 own poll method. Fixed my moving _deadstate to an _internal_poll method.
151
Gregory P. Smith7641b1c2008-08-04 03:23:25 +0000152- Issue #2113: Fix error in subprocess.Popen if the select system call is
153 interrupted by a signal.

Gregory P. Smith5e8dc972008-08-17 23:01:11 +0000155- Issue #874900: after an os.fork() call the threading module state is cleaned
156 up in the child process to prevent deadlock and report proper thread counts
157 if the new process uses the threading module.

Lars Gustäbeld2201442007-04-20 14:49:02 +0000220What's New in Python 2.5.2c1?
221=============================
222
Martin v. Löwisa859e252008-02-14 12:33:15 +0000223*Release date: 14-Feb-2008*

Martin v. Löwis897704d2007-06-08 17:29:40 +0000225Core and builtins
226-----------------
227
Martin v. Löwis73c01d42008-02-14 11:26:18 +0000228- Added checks for integer overflows, contributed by Google. Some are

234
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000235- Issue #1920: "while 0" statements were completely removed by the compiler,
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000236 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000237 the condition is false. Now the compiler correctly emits bytecode for the
238 "else" suite.
239
Guido van Rossumd933e0a2008-01-24 18:28:37 +0000240- A few crashers fixed: weakref_in_del.py (issue #1377858);

267 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
268 results with huge strings.

Guido van Rossumc69ac252006-08-10 18:09:25 +00001190What's New in Python 2.5 release candidate 1?
1191=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001192
Anthony Baxterb4096662006-08-16 03:42:26 +00001193*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001194
1195Core and builtins
1196-----------------
1197
Neal Norwitz24b6f202006-09-05 04:43:56 +00001198- Fix infinite recursion when subclassing long and overriding __hash__.
1199
1200- Fix concatenation (+=) of long strings.
1201
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001202- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001203 compared equal or unequal to a string and a UnicodeDecodeError
1204 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001205
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001206 Instead, the equal (==) and unequal (!=) comparison operators will
1207 now issue a UnicodeWarning and interpret the two objects as
1208 unequal. The UnicodeWarning can be filtered as desired using
1209 the warning framework, e.g. silenced completely, turned into an
1210 exception, logged, etc.
1211
1212 Note that compare operators other than equal and unequal will still
1213 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001214
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001215- Fix segfault when doing string formatting on subclasses of long.
1216
1217- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1218 with new-style classes.
1219
1220- Fix bug related to __len__ functions returning negative values with
1221 classic classes.
1222
1223- Patch #1538606, Fix __index__() clipping. There were some problems
1224 discovered with the API and how integers that didn't fit into Py_ssize_t
1225 were handled. This patch attempts to provide enough alternatives
1226 to effectively use __index__.
1227
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001228- Bug #1536021: __hash__ may now return long int; the final hash
1229 value is obtained by invoking hash on the long int.
1230
Thomas Hellerab1049c2006-08-08 17:37:00 +00001231- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1232
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001233- Bug #1535165: fixed a segfault in input() and raw_input() when
1234 sys.stdin is closed.
1235
Thomas Heller74d36f02006-08-04 18:17:40 +00001236- On Windows, the PyErr_Warn function is now exported from
1237 the Python dll again.
1238
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001239- Bug #1191458: tracing over for loops now produces a line event
1240 on each iteration. Fixing this problem required changing the .pyc
1241 magic number. This means that .pyc files generated before 2.5c1
1242 will be regenerated.
1243
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001244- Bug #1333982: string/number constants were inappropriately stored
1245 in the byte code and co_consts even if they were not used, ie
1246 immediately popped off the stack.
1247
Georg Brandle9462c72006-08-04 18:03:37 +00001248- Fixed a reference-counting problem in property().
1249
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001250
1251Library
1252-------
1253
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001254- Fix a bug in the ``compiler`` package that caused invalid code to be
1255 generated for generator expressions.
1256
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001257- The distutils version has been changed to 2.5.0. The change to
1258 keep it programmatically in sync with the Python version running
1259 the code (introduced in 2.5b3) has been reverted. It will continue
1260 to be maintained manually as static string literal.
1261
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001262- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001263 and this cannot be converted to the required C type, an exception is
1264 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001265 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001266
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001267- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001268 an exception.
1269
Tim Peterscbdd3502006-09-05 01:47:53 +00001270- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001271 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001272 workarounds for clocks with low resolution, to stop the code yielding
1273 duplicate UUIDs.
1274
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001275- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1276 before raising SystemExit, allowing IDLE to honor quit() and exit().
1277
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001278- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1279
Georg Brandl7a1af772006-08-14 21:55:28 +00001280- Patch #1536071: trace.py should now find the full module name of a
1281 file correctly even on Windows.
1282
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001283- logging's atexit hook now runs even if the rest of the module has
1284 already been cleaned up.
1285
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001286- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001287
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001288- Bug #1531405, format_exception no longer raises an exception if
1289 str(exception) raised an exception.
1290
Neil Schemenauer06ded092006-08-04 16:20:30 +00001291- Fix a bug in the ``compiler`` package that caused invalid code to be
1292 generated for nested functions.
1293
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001294
1295Extension Modules

Georg Brandl3335a7a2006-08-14 21:42:55 +00001302- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1303 raises the correct exceptions.
1304
Thomas Heller1ce433e2006-08-14 16:20:04 +00001305- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1306 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1307
Thomas Heller86720042006-08-14 11:17:48 +00001308- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1309 uses the _as_parameter_ attribute when objects are passed to foreign
1310 function calls. The ctypes version number was changed to 1.0.1.
1311
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001312- Bug #1530559, struct.pack raises TypeError where it used to convert.
1313 Passing float arguments to struct.pack when integers are expected
1314 now triggers a DeprecationWarning.

1349-----
1350
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001351- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1352
Tim Peters4643c2f2006-08-10 22:45:34 +00001353- Bug #1069160. Internal correctness changes were made to
1354 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1355 the documentation was changed to state that the return value
1356 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001359What's New in Python 2.5 beta 3?
1360================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001361
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001362*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001363
1364Core and builtins
1365-----------------
1366
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001367- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001368 returned a long (see PEP 353).
1369
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001370- Bug #1515471: string.replace() accepts character buffers again.
1371
Neal Norwitz07aadb12006-07-30 06:55:48 +00001372- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1373 This provides the proper warning for struct.pack().
1374 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1375
Neal Norwitz0d62a062006-07-30 06:53:31 +00001376- Patch #1531113: Fix augmented assignment with yield expressions.
1377 Also fix a SystemError when trying to assign to yield expressions.
1378
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001379- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1380 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1381 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1382 excessive filesystem operations during imports.
1383
Tim Petersbc24eee2006-07-27 01:14:53 +00001384- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1385 operations on signed longs that are formally undefined by C.
1386 Unfortunately, at least one compiler now cares about that, so complicated
1387 the code to make that compiler happy again.
1388
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001389- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1390
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001391- Patch #1232023: Stop including current directory in search
1392 path on Windows.
1393
Neal Norwitze1fdb322006-07-21 05:32:28 +00001394- Fix some potential crashes found with failmalloc.
1395
Neal Norwitze7563102006-07-17 01:00:16 +00001396- Fix warnings reported by Klocwork's static analysis tool.
1397
Neal Norwitz84be93b2006-07-16 01:50:38 +00001398- Bug #1512814, Fix incorrect lineno's when code within a function
1399 had more than 255 blank lines.
1400
Georg Brandl9dceedb2006-07-12 15:31:17 +00001401- Patch #1521179: Python now accepts the standard options ``--help`` and
1402 ``--version`` as well as ``/?`` on Windows.
1403
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001404- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001405 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001406 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001407
Tim Peters112aad32006-07-19 00:03:19 +00001408- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001409 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001410 new ``sys._current_frames()`` returns a dictionary with one entry,
1411 mapping the faux "thread id" 0 to the current frame.
1412
Ronald Oussoren3075e162006-07-25 20:28:55 +00001413- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001414
Ronald Oussoren3075e162006-07-25 20:28:55 +00001415
Neal Norwitza1f10902006-07-12 07:28:29 +00001416Library
1417-------
1418
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001419- Correction of patch #1455898: In the mbcs decoder, set final=False
1420 for stream decoder, but final=True for the decode function.
1421
Georg Brandl07fec3a2006-08-01 18:49:24 +00001422- os.urandom no longer masks unrelated exceptions like SystemExit or
1423 KeyboardInterrupt.
1424
Tim Peters4643c2f2006-08-10 22:45:34 +00001425- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001426 shutil.copytree on Windows
1427
Georg Brandle34ac7c2006-07-30 11:07:23 +00001428- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1429 refers to file descriptors, not file objects.
1430
Tim Peterscbdd3502006-09-05 01:47:53 +00001431- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001432 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001433 #1513611, and probably others.
1434
Georg Brandledd9b0d2006-07-29 09:33:26 +00001435- Bug #1441397: The compiler module now recognizes module and function
1436 docstrings correctly as it did in Python 2.4.
1437
Tim Peters6f681472006-07-27 23:44:37 +00001438- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1439 lost that tests are sorted by name before being run. This rarely
1440 matters for well-written tests, but can create baffling symptoms if
1441 side effects from one test to the next affect outcomes. ``DocTestFinder``
1442 has been changed to sort the list of tests it returns.
1443
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001444- The distutils version has been changed to 2.5.0, and is now kept

Martin v. Löwis9298eff2006-07-26 12:12:56 +00001447- Bug #978833: Really close underlying socket in _socketobject.close.
1448
Georg Brandldb232dc2006-08-20 13:15:43 +00001449- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1450 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001451
Georg Brandlcf0c1722006-07-26 07:23:32 +00001452- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1453 to recursive calls and call it with the failing package name.
1454
Martin v. Löwis0b483032006-07-25 09:53:12 +00001455- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1456
Georg Brandlc13c34c2006-07-24 14:09:56 +00001457- Patch #1515343: Fix printing of deprecated string exceptions with a
1458 value in the traceback module.
1459
Greg Ward48fae7a2006-07-23 16:05:51 +00001460- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1461
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001462- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1463
Brett Cannoncaebe222006-07-18 04:41:36 +00001464- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1465 argument tuple. For arguments where zero is illegal, the value is forced to
1466 the minimum value that is correct. This is to support an undocumented but
1467 common way people used to fill in inconsequential information in the time
1468 tuple pre-2.4.
1469
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001470- Patch #1220874: Update the binhex module for Mach-O.
1471
Barry Warsawb110bad2006-07-21 14:51:07 +00001472- The email package has improved RFC 2231 support, specifically for
1473 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1474 (name*0=<blah>) parameter continuations. This may change the types of
1475 values returned from email.message.Message.get_param() and friends.
1476 Specifically in some cases where non-encoded continuations were used,
1477 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1478 will just return the string (since non-encoded continuations don't have
1479 charset and language parts).
1480
1481 Also, whereas % values were decoded in all parameter continuations, they are
1482 now only decoded in encoded parameter parts.
1483
Ronald Oussoren3075e162006-07-25 20:28:55 +00001484- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1485
1486- Bug #1517996: IDLE now longer shows the default Tk menu when a
1487 path browser, class browser or debugger is the frontmost window on MacOS X
1488
Barry Warsaw00decd72006-07-27 23:43:15 +00001489- Patch #1520294: Support for getset and member descriptors in types.py,
1490 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1491 of an object against these built-in types and more importantly, for getting
1492 their docstrings printed in the interactive interpreter's help() function.

1496-----------------
1497
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001498- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1499 a socket operation on a socket with a timeout, the exception will be
1500 caught correctly. Previously, the exception was not caught.
1501
Thomas Heller1393d6a2006-07-28 21:43:20 +00001502- Patch #1529514: The _ctypes extension is now compiled on more
1503 openbsd target platforms.
1504
Tim Peters9cab5932006-07-28 00:30:00 +00001505- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1506 a memory leak, affecting pickles and deep copies.
1507
Tim Petersbc24eee2006-07-27 01:14:53 +00001508- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1512
Thomas Hellerce049a02006-07-14 17:51:14 +00001513- Patch #1521817: Index range checking on ctypes arrays containing
1514 exactly one element enabled again. This allows iterating over these
1515 arrays, without the need to check the array size before.
1516
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001517- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001518 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001519 /dev/null in certain cases; this is now fixed.
1520
Thomas Heller47d7a062006-07-12 08:43:47 +00001521- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1522 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001523
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001524- Because of a misspelled preprocessor symbol, ctypes was always
1525 compiled without thread support; this is now fixed.
1526
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001527- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1528 methods now allow their database parameter to be None as the
1529 sleepycat API allows.
1530
Matt Flemingec926502006-07-28 11:27:27 +00001531- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1532 bluetooth API compared with Linux and FreeBSD.
1533
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001534Tests
1535-----
1536
1537- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1538 how long the test file should take to play. Now accepts taking 2.93 secs
1539 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1540
Georg Brandl4793aa32006-07-28 18:31:39 +00001541- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1542 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1543 run via ``regrtest.py``. Now they do.

1548- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1549
Ronald Oussoren26cad082006-08-01 21:00:57 +00001550Mac
1551---
1552
1553- PythonLauncher now works correctly when the path to the script contains
1554 characters that are treated specially by the shell (such as quotes).
1555
1556- Bug #1527397: PythonLauncher now launches scripts with the working directory
1557 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001558 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001559 expect.

1568-----------------
1569
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001570- Bug #1441486: The literal representation of -(sys.maxint - 1)
1571 again evaluates to a int object, not a long.
1572
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001573- Bug #1501934: The scope of global variables that are locally assigned
1574 using augmented assignment is now correctly determined.
1575
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001576- Bug #927248: Recursive method-wrapper objects can now safely
1577 be released.
1578
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001579- Bug #1417699: Reject locale-specific decimal point in float()
1580 and atof().
1581
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001582- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1583 omit a default "error" argument for NULL pointer. This allows
1584 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001585
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001586- Bug #1519018: 'as' is now validated properly in import statements.
1587
Neal Norwitz28746ab2006-07-09 22:14:42 +00001588- On 64 bit systems, int literals that use less than 64 bits are
1589 now ints rather than longs.
1590
Neal Norwitzed657552006-07-10 00:04:44 +00001591- Bug #1512814, Fix incorrect lineno's when code at module scope
1592 started after line 256.
1593
Tim Peters32a83612006-07-10 21:08:24 +00001594- New function ``sys._current_frames()`` returns a dict mapping thread
1595 id to topmost thread stack frame. This is for expert use, and is
1596 especially useful for debugging application deadlocks. The functionality
1597 was previously available in Fazal Majid's ``threadframe`` extension
1598 module, but it wasn't possible to do this in a wholly threadsafe way from
1599 an extension.

1616
Thomas Woutersadd19112006-07-05 11:03:49 +00001617- string.Template() now correctly handles tuple-values. Previously,
1618 multi-value tuples would raise an exception and single-value tuples would
1619 be treated as the value they contain, instead.
1620
Martin v. Löwisede77f52006-07-03 13:01:35 +00001621- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1628 degrees and radians.
1629
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001630- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001631 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001632

1634 is created.
1635
Martin v. Löwis7596e832006-07-01 15:33:37 +00001636- Bug #1513223: .close() of a _socketobj now releases the underlying
1637 socket again, which then gets closed as it becomes unreferenced.

1642- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1643 sgmllib ('[' and ']' were not accepted).
1644
Georg Brandl1be63af2006-06-28 20:23:25 +00001645- Fix a bug in the turtle module's end_fill function.
1646
Brett Cannon53ab5b72006-06-22 16:49:14 +00001647- Bug #1510580: The 'warnings' module improperly required that a Warning
1648 category be either a types.ClassType and a subclass of Warning. The proper
1649 check is just that it is a subclass with Warning as the documentation states.
1650
Georg Brandlad29e632006-06-21 17:45:17 +00001651- The compiler module now correctly compiles the new try-except-finally
1652 statement (bug #1509132).
1653
Neal Norwitz60373cd2006-06-22 06:30:50 +00001654- The wsgiref package is now installed properly on Unix.
1655
Vinay Sajip28e57612006-07-01 10:45:20 +00001656- A bug was fixed in logging.config.fileConfig() which caused a crash on
1657 shutdown when fileConfig() was called multiple times.
1658
Gerhard Häring762fbd32006-07-02 17:48:30 +00001659- The sqlite3 module did cut off data from the SQLite database at the first
1660 null character before sending it to a custom converter. This has been fixed
1661 now.
1662
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001663Extension Modules
1664-----------------
1665
Tim Peters112aad32006-07-19 00:03:19 +00001666- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1667 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1668 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001669
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001670- Assigning None to pointer type fields in ctypes structures possible
1671 overwrote the wrong fields, this is fixed now.
1672
1673- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1674 on non-Windows platforms.
1675
1676- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1677 integer or long, without range checking.
1678
1679- Patch #1517790: It is now possible to use custom objects in the ctypes
1680 foreign function argtypes sequence as long as they provide a from_param
1681 method, no longer is it required that the object is a ctypes type.
1682
1683- The '_ctypes' extension module now works when Python is configured
1684 with the --without-threads option.
1685
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001686- Bug #1513646: os.access on Windows now correctly determines write

1701
Tim Peters32a83612006-07-10 21:08:24 +00001702- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001703 Previously, the slight difference could cause compilation errors of the
1704 'zlib' module on systems with more than one version of zlib.
1705
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001706- The MSI compileall step was fixed to also support a TARGETDIR
1707 with spaces in it.

1741 (such as iterating over an integer) have been improved and now include the
1742 type of the offending object to help with debugging.
1743
Brett Cannonea3912b2006-06-13 21:46:41 +00001744- Bug #992017: A classic class that defined a __coerce__() method that returned
1745 its arguments swapped would infinitely recurse and segfault the interpreter.
1746
Neal Norwitz909eb122006-06-12 02:13:21 +00001747- Fix the socket tests so they can be run concurrently.
1748
Neal Norwitzb9845e72006-06-12 02:11:18 +00001749- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001750 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001751
Brett Cannon22565aa2006-06-09 22:31:23 +00001752- Bug #532646: object.__call__() will continue looking for the __call__
1753 attribute on objects until one without one is found. This leads to recursion
1754 when you take a class and set its __call__ attribute to an instance of the
1755 class. Originally fixed for classic classes, but this fix is for new-style.
1756 Removes the infinite_rec_3 crasher.
1757
Georg Brandl24250812006-06-09 18:45:48 +00001758- The string and unicode methods startswith() and endswith() now accept
1759 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1760
Brett Cannonde3b0522006-06-08 17:00:45 +00001761- Buffer objects, at the C level, never used the char buffer
1762 implementation even when the char buffer for the wrapped object was
1763 explicitly requested (originally returned the read or write buffer).
1764 Now a TypeError is raised if the char buffer is not present but is
1765 requested.
1766
Georg Brandlddbaa662006-06-04 21:56:52 +00001767- Patch #1346214: Statements like "if 0: suite" are now again optimized
1768 away like they were in Python 2.4.
1769
Georg Brandlb7c8f542006-05-27 12:30:25 +00001770- Builtin exceptions are now full-blown new-style classes instead of
1771 instances pretending to be classes, which speeds up exception handling
1772 by about 80% in comparison to 2.5a2.
1773
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001774- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1775 Unicode 4.1.
1776
Georg Brandlf4ef1162006-05-26 18:03:31 +00001777- Patch #921466: sys.path_importer_cache is now used to cache valid and
1778 invalid file paths for the built-in import machinery which leads to
1779 fewer open calls on startup.
1780
Tim Peters696cf432006-05-24 21:10:40 +00001781- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1782 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1783 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1784 the number of input digits (it was and remains linear-time for bases
1785 2, 4, 8, 16 and 32).
1786
Tim Petersb713ec22006-05-23 18:45:30 +00001787- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1788 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1789 an integer close to ``sys.maxint``. This was repaired by patch
1790 #1335972, which also gives a nice speedup.
1791
Richard Jonescebbefc2006-05-23 18:28:17 +00001792- Patch #1337051: reduced size of frame objects.
1793
1794- PyErr_NewException now accepts a tuple of base classes as its
1795 "base" parameter.
1796
Richard Jones7c88dcc2006-05-23 10:37:38 +00001797- Patch #876206: function call speedup by retaining allocated frame
1798 objects.
1799
Georg Brandl7b90e162006-05-18 07:01:27 +00001800- Bug #1462152: file() now checks more thoroughly for invalid mode
1801 strings and removes a possible "U" before passing the mode to the
1802 C library function.
1803
Neal Norwitz1004a532006-05-15 07:17:23 +00001804- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1805
Neal Norwitz373f0a72006-05-15 07:04:36 +00001806- Bug #1487966: Fix SystemError with conditional expression in assignment
1807
Martin v. Löwis879768d2006-05-11 13:28:43 +00001808- WindowsError now has two error code attributes: errno, which carries
1809 the error values from errno.h, and winerror, which carries the error
1810 values from winerror.h. Previous versions put the winerror.h values
1811 (from GetLastError()) into the errno attribute.
1812
Martin v. Löwis77736712006-05-04 05:51:03 +00001813- Patch #1475845: Raise IndentationError for unexpected indent.
1814
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001815- Patch #1479181: split open() and file() from being aliases for each other.
1816
Tim Peters44bd9862006-06-01 13:49:23 +00001817- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1818 methods were always silently ignored by dictionaries when comparing keys.
1819 They are now passed through (except when using the C API function
1820 ``PyDict_GetItem()``, whose semantics did not change).
1821
1822- Bug #1456209: In some obscure cases it was possible for a class with a
1823 custom ``__eq__()`` method to confuse dict internals when class instances
1824 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1825 No, you don't have any code that did this ;-)

1828-----------------
1829
Trent Mick960a3f82006-06-28 20:30:41 +00001830- Bug #1295808: expat symbols should be namespaced in pyexpat
1831
1832- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1833
Brett Cannon6ee7d012006-06-08 16:23:04 +00001834- Change binascii.hexlify to accept a read-only buffer instead of only a char
1835 buffer and actually follow its documentation.
1836
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001837- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1838
Nick Coghlanc649ec52006-05-29 12:43:05 +00001839- Patch #1478788 (modified version): The functional extension module has
1840 been renamed to _functools and a functools Python wrapper module added.
1841 This provides a home for additional function related utilities that are
1842 not specifically about functional programming. See PEP 309.
1843
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001844- Patch #1493701: performance enhancements for struct module.
1845
Georg Brandl378d5922006-05-17 14:26:50 +00001846- Patch #1490224: time.altzone is now set correctly on Cygwin.
1847
Georg Brandl8d3342b2006-05-16 07:38:27 +00001848- Patch #1435422: zlib's compress and decompress objects now have a
1849 copy() method.
1850
Andrew MacIntyre92913322006-06-13 15:04:24 +00001851- Patch #1454481: thread stack size is now tunable at runtime for thread
1852 enabled builds on Windows and systems with Posix threads support.
1853
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001854- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1855 (up to the system limit of 32K characters).
1856
1857- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1858 As a result, these functions now raise WindowsError instead of OSError.
1859
Tim Peters7a822da2006-05-25 21:50:17 +00001860- ``time.clock()`` on Win64 should use the high-performance Windows
1861 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1862 Windows platforms).
1863
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001864- Calling Tk_Init twice is refused if the first call failed as that
1865 may deadlock.
1866
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001867- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1868 accept it without potentially using an uninitialized pointer.
1869
1870- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1871 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1872 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001873
Gregory P. Smith372b5832006-06-05 18:48:21 +00001874- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001875 [pybsddb project SF patch number 1466734]
1876
Gregory P. Smith372b5832006-06-05 18:48:21 +00001877- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1878 parameter is supplied. [SF pybsddb bug #1477863]
1879
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001880- bsddb: the __len__ method of a DB object has been fixed to return correct
1881 results. It could previously incorrectly return 0 in some cases.
1882 Fixes SF bug 1493322 (pybsddb bug 1184012).
1883
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001884- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1885 aborts the db transaction safely when a modifier callback fails.
1886 Fixes SF python patch/bug #1408584.
1887
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001888- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001889 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001890 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1891 database calls that would previously deadlock. [SF python bug #775414]
1892
Vinay Sajip28e57612006-07-01 10:45:20 +00001893- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001894
Walter Dörwald4994d952006-06-19 08:07:50 +00001895- Patch #1506645: add Python wrappers for the curses functions
1896 is_term_resized, resize_term and resizeterm.

1900
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001901- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1902 functions.
1903
Martin v. Löwis3798da02006-06-17 18:44:27 +00001904- Patch #812986: Update turtle output even if not tracing.
1905
Vinay Sajip28e57612006-07-01 10:45:20 +00001906- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001907 Tkinter.BaseWidget.
1908
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001909- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1910
Martin v. Löwis337487e2006-06-17 09:15:14 +00001911- Patch #763580: Add name and value arguments to Tkinter variable
1912 classes.
1913
Georg Brandl83cc0d02006-06-14 08:50:03 +00001914- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1915 mime.types file for determining MIME types.
1916
Georg Brandl2605ca82006-06-14 06:08:31 +00001917- Bug #1339007: Shelf objects now don't raise an exception in their
1918 __del__ method when initialization failed.
1919
Martin v. Löwisd8251432006-06-14 05:21:04 +00001920- Patch #1455898: The MBCS codec now supports the incremental mode for
1921 double-byte encodings.
1922
Tim Peters43898b42006-06-14 04:09:25 +00001923- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1924 guarantee that adjacent triples in the return list always describe
1925 non-adjacent blocks. Previously, a pair of matching blocks could end
1926 up being described by multiple adjacent triples that formed a partition
1927 of the matching pair.
1928
Greg Ward0e0c9f42006-06-11 16:24:11 +00001929- Bug #1498146: fix optparse to handle Unicode strings in option help,
1930 description, and epilog.
1931
Greg Wardd1c797e2006-06-11 14:42:41 +00001932- Bug #1366250: minor optparse documentation error.
1933
Greg Ward7f547402006-06-11 00:40:49 +00001934- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1935 clarify docs.
1936
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001937- The wsgiref package has been added to the standard library.
1938
Nick Coghlan676725d2006-06-08 13:54:49 +00001939- The functions update_wrapper() and wraps() have been added to the functools
1940 module. These make it easier to copy relevant metadata from the original
1941 function when writing wrapper functions.
1942
Tim Petersd6a9eef2006-06-05 01:48:21 +00001943- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1944 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001945
Martin v. Löwis3f767792006-06-04 19:36:28 +00001946- Patch #1359618: Speed up charmap encoder by using a trie structure
1947 for lookup.
1948
Tim Petersd609b1a2006-06-02 23:22:51 +00001949- The functions in the ``pprint`` module now sort dictionaries by key
1950 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1951 if and only if its display required more than one line, although that
1952 wasn't documented. The new behavior increases predictability; e.g.,
1953 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1954
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001955- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1956 (thanks for J. J. Lee).
1957
Georg Brandl2b330372006-05-28 20:23:12 +00001958- Patch #1496206: improve urllib2 handling of passwords with respect to
1959 default HTTP and HTTPS ports.
1960
George Yoshidaf3c65de2006-05-28 16:39:09 +00001961- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1962
Bob Ippolito7298f272006-05-23 18:43:47 +00001963- Patch #1281707: speed up gzip.readline.
1964
Georg Brandlb89316f2006-05-17 15:51:16 +00001965- Patch #1180296: Two new functions were added to the locale module:
1966 format_string() to get the effect of "format % items" but locale-aware,
1967 and currency() to format a monetary number with currency sign.
1968
Georg Brandle3a25832006-05-17 14:56:04 +00001969- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1970 and several features added, such as speed and geometry control.
1971
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001972- Patch #1488881: add support for external file objects in bz2 compressed
1973 tarfiles.
1974
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001975- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1976 stdout arguments, making it possible to redirect input and output
1977 for remote debugging.
1978
1979- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1980 a couple of issues, notably handling of long file names using the
1981 GNU LONGNAME extension.
1982
1983- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1984 new flag when ``name`` is already the name of an option flag.
1985
1986- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1987 package.
1988
1989- Patch #1472854: make the rlcompleter.Completer class usable on non-
1990 UNIX platforms.
1991
1992- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1993
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001994- Bug #1472827: correctly escape newlines and tabs in attribute values in
1995 the saxutils.XMLGenerator class.

2031-----------------
2032
Thomas Heller1b046642006-04-18 18:51:06 +00002033- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2034 by converting these apis from macros into exported functions again:
2035
2036 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile

2041
Martin v. Löwis45294a92006-04-18 06:24:08 +00002042- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2043
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002044- All uses of PyStructSequence_InitType have been changed to initialize
2045 the type objects only once, even if the interpreter is initialized
2046 multiple times.
2047
Neal Norwitz61546162006-04-14 05:20:28 +00002048- Bug #1454485, array.array('u') could crash the interpreter. This was
2049 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2050 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2051
2052- Py_UNICODE is unsigned. It was always documented as unsigned, but
2053 due to a bug had a signed value in previous versions.
2054
Tim Peters3a5e8b12006-04-11 01:44:07 +00002055- Patch #837242: ``id()`` of any Python object always gives a positive
2056 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2057 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002058 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002059 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002060
Tim Peters3a5e8b12006-04-11 01:44:07 +00002061 def __hash__(self):
2062 return id(self) # WRONG
2063
2064 because a hash result must be a (short) Python int but it was always
2065 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002066 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002067 was always usable as a hash value before this patch. That's no longer
2068 necessarily so.
2069
2070- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002071 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002072 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002073 #1454844)
2074
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002075- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2076 involving generators that have paused outside of any ``try`` or ``with``
2077 blocks. (In 2.5a1, a paused generator that was part of a reference
2078 cycle could not be garbage collected, regardless of whether it was
2079 paused in a ``try`` or ``with`` block.)

2086
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002087- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2088 fails with an error condition.
2089
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002090- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2091
2092- Bug #1117761: bsddb.*open() no longer raises an exception when using
2093 the cachesize parameter.
2094

2096 a temporary db (file=None) with the 'n' flag to truncate on open.
2097
2098- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2099 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002100
Armin Rigoa9017c32006-04-19 11:50:27 +00002101- Patch #1062014: AF_UNIX sockets under Linux have a special
2102 abstract namespace that is now fully supported.

2105-------
2106
Peter Astrand7d1d4362006-07-14 14:04:45 +00002107- Bug #1223937: subprocess.CalledProcessError reports the exit status
2108 of the process using the returncode attribute, instead of
2109 abusing errno.
2110
Tim Peters711bf302006-04-25 03:31:36 +00002111- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2112 a doctest to be skipped (the code is not run, and the expected output
2113 or exception is ignored).
2114
Nick Coghlanda2268f2006-04-24 04:37:15 +00002115- Fixed contextlib.nested to cope with exceptions being raised and
2116 caught inside exit handlers.
2117
Greg Wardab05edc2006-04-23 03:47:58 +00002118- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2119 hex, octal, or binary; add ``append_const`` action; keep going if
2120 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2121 added ``epilog`` for better help generation).
2122
Tim Peters21fbd572006-04-21 21:18:10 +00002123- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2124 called from a thread spawned as a side effect of importing a module.
2125
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002126- The pydoc module now supports documenting packages contained in
2127 .zip or .egg files.
2128
2129- The pkgutil module now has several new utility functions, such
2130 as ``walk_packages()`` to support working with packages that are either
2131 in the filesystem or zip files.
2132
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002133- The mailbox module can now modify and delete messages from
2134 mailboxes, in addition to simply reading them. Thanks to Gregory
2135 K. Johnson for writing the code, and to the 2005 Google Summer of
2136 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002137
Tim Petersc7605f22006-04-17 21:12:33 +00002138- The ``__del__`` method of class ``local`` in module ``_threading_local``

Anthony Baxtere29002c2006-04-12 12:07:31 +00002147- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2148 Windows. Bug #1469163.
2149
Phillip J. Eby47032112006-04-11 01:07:43 +00002150- The warnings, linecache, inspect, traceback, site, and doctest modules
2151 were updated to work correctly with modules imported from zipfiles or
2152 via other PEP 302 __loader__ objects.
2153
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002154- Patch #1467770: Reduce usage of subprocess._active to processes which

2160
Skip Montanaro262fb922006-04-21 02:31:07 +00002161- The pstats.Stats class accepts an optional stream keyword argument to
2162 direct output to an alternate file-like object.
2163

2165-----
2166
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002167- The Makefile now has a reindent target, which runs reindent.py on
2168 the library.
2169
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002170- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002173
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002174- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2175 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002176 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002177 CXX from --with-cxx-main, see description in README.
2178
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002179- Patch #1429775: Link extension modules with the shared libpython.
2180
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002181- Fixed a libffi build problem on MIPS systems.
2182
Tim Peters8931ff12006-05-13 23:28:20 +00002183- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2184 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2185 and "%zu" for unsigned integers of type ``size_t``.
2186

2188-----
2189
Nick Coghlanda2268f2006-04-24 04:37:15 +00002190- test_contextlib now checks contextlib.nested can cope with exceptions
2191 being raised and caught inside exit handlers.
2192
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002193- test_cmd_line now checks operation of the -m and -c command switches
2194
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002195- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2196 it separately and by hand. It also wasn't cleaning up its changes to
2197 the current Decimal context.
2198
Thomas Woutersabd08882006-04-26 15:53:30 +00002199- regrtest.py now has a -M option to run tests that test the new limits of
2200 containers, on 64-bit architectures. Running these tests is only sensible
2201 on 64-bit machines with more than two gigabytes of memory. The argument
2202 passed is the maximum amount of memory for the tests to use.

2211-------------
2212
Tim Petersb06d28c2006-05-12 01:57:59 +00002213- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2214
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002215- PEP 343: Added Context Types section to the library reference
2216 and attempted to bring other PEP 343 related documentation into
2217 line with the implementation and/or python-dev discussions.
2218
Tim Peters8dc73d22006-04-24 02:03:16 +00002219- Bug #1337990: clarified that ``doctest`` does not support examples
2220 requiring both expected output and an exception.

Anthony Baxterebed3f62006-04-03 15:03:44 +00002226*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002227
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002228Core and builtins
2229-----------------
2230
Nick Coghlan43832302006-04-23 17:04:07 +00002231- PEP 338: -m command line switch now delegates to runpy.run_module
2232 allowing it to support modules in packages and zipfiles
2233
Martin v. Löwisc661b882006-04-20 04:54:23 +00002234- On Windows, .DLL is not an accepted file name extension for
2235 extension modules anymore; extensions are only found if they
2236 end in .PYD.
2237
Martin v. Löwisea62d252006-04-03 10:56:49 +00002238- Bug #1421664: sys.stderr.encoding is now set to the same value as
2239 sys.stdout.encoding.
2240
Neal Norwitz92e212f2006-04-03 04:48:37 +00002241- __import__ accepts keyword arguments.
2242
Georg Brandlccadf842006-03-31 18:54:53 +00002243- Patch #1460496: round() now accepts keyword arguments.
2244
Anthony Baxter262c00a2006-03-30 10:53:17 +00002245- Fixed bug #1459029 - unicode reprs were double-escaped.
2246
Hye-Shik Changd478f342006-03-23 12:32:36 +00002247- Patch #1396919: The system scope threads are reenabled on FreeBSD
2248 5.4 and later versions.
2249
Neal Norwitze98ccf62006-03-23 05:39:47 +00002250- Bug #1115379: Compiling a Unicode string with an encoding declaration
2251 now gives a SyntaxError.
2252
Georg Brandlabd1ff82006-03-18 07:59:59 +00002253- Previously, Python code had no easy way to access the contents of a
2254 cell object. Now, a ``cell_contents`` attribute has been added
2255 (closes patch #1170323).
2256
Tim Peterscf79aac2006-03-16 01:14:46 +00002257- Patch #1123430: Python's small-object allocator now returns an arena to
2258 the system ``free()`` when all memory within an arena becomes unused
2259 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2260 freed. Some applications will see a drop in virtual memory size now,
2261 especially long-running applications that, from time to time, temporarily
2262 use a large number of small objects. Note that when Python returns an
2263 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002264 platform C library will in turn return that memory to the operating system.
2265 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002266 appears to be effective at least on Microsoft C and gcc-based systems.
2267 Thanks to Evan Jones for hard work and patience.
2268
Georg Brandl533ff6f2006-03-08 18:09:27 +00002269- Patch #1434038: property() now uses the getter's docstring if there is
2270 no "doc" argument given. This makes it possible to legitimately use
2271 property() as a decorator to produce a read-only property.
2272
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002273- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2274 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2275 of requiring an int or long in slicing and a few other contexts, enabling
2276 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2277
Neal Norwitz995acdf2006-03-07 05:01:00 +00002278- Fixed various bugs reported by Coverity's Prevent tool.
2279
Brett Cannonbf364092006-03-01 04:25:17 +00002280- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2281 new exception base class, BaseException, which has a new message attribute.
2282 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2283 Raising a string exception now raises a DeprecationWarning.
2284
Thomas Woutersfb609f42006-02-28 16:37:25 +00002285- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2286 explicitly relative, using 'from .module import name' to mean 'from the same
2287 package as this module is in. Imports without dots still default to the
2288 old relative-then-absolute, unless 'from __future__ import
2289 absolute_import' is used.
2290
Brett Cannona7446e32006-02-27 23:39:10 +00002291- Properly check if 'warnings' raises an exception (usually when a filter set
2292 to "error" is triggered) when raising a warning for raising string
2293 exceptions.
2294
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002295- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002296 The name was removed from Include/code.h.
2297
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002298- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002299
Guido van Rossum1968ad32006-02-25 22:38:04 +00002300- Patch 1433928:
2301 - The copy module now "copies" function objects (as atomic objects).
2302 - dict.__getitem__ now looks for a __missing__ hook before raising
2303 KeyError.
2304
Tim Peters84ef21c2006-02-28 20:39:06 +00002305- PEP 343: with statement implemented. Needs ``from __future__ import
2306 with_statement``. Use of 'with' as a variable will generate a warning.
2307 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002308 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002309 The following objects have __context__ methods:
2310 - The built-in file type.
2311 - The thread.LockType type.
2312 - The following types defined by the threading module:
2313 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2314 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002315
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002316- Fix the encodings package codec search function to only search
2317 inside its own package. Fixes problem reported in patch #1433198.
2318
2319 Note: Codec packages should implement and register their own
2320 codec search function. PEP 100 has the details.
2321
Tim Peters9ea89d22006-06-04 03:26:02 +00002322- PEP 353: Using ``Py_ssize_t`` as the index type.
2323
2324- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2325 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2326 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2327 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2328 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002329
Neal Norwitzfc76d632006-01-10 06:03:13 +00002330- Patch #1400181, fix unicode string formatting to not use the locale.
2331 This is how string objects work. u'%f' could use , instead of .
2332 for the decimal point. Now both strings and unicode always use periods.
2333
Neal Norwitz671b9e32006-01-09 07:07:12 +00002334- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2335 configure would break checking curses.h.
2336
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002337- Bug #959576: The pwd module is now builtin. This allows Python to be
2338 built on UNIX platforms without $HOME set.
2339
Neal Norwitzc10978f2005-12-19 06:07:16 +00002340- Bug #1072182, fix some potential problems if characters are signed.
2341
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002342- Bug #889500, fix line number on SyntaxWarning for global declarations.
2343
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002344- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2345
Neal Norwitze7214a12005-12-18 05:03:17 +00002346- Support for converting hex strings to floats no longer works.
2347 This was not portable. float('0x3') now raises a ValueError.
2348
Barry Warsaw2a38a862005-12-18 01:27:35 +00002349- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002350 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002351 is now displayed in interactive prompt banner.
2352
Georg Brandlfa166682005-12-17 21:45:17 +00002353- Implementation of PEP 341 - Unification of try/except and try/finally.
2354 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002355 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002356
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002357- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2358 now encodes backslash correctly.
2359
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002360- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2361
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002362- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002363 and long longs.
2364
Neal Norwitz67715f02005-11-09 06:59:35 +00002365- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002366 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002367 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002368
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002369- Replaced most Unicode charmap codecs with new ones using the
2370 new Unicode translate string feature in the builtin charmap
2371 codec; the codecs were created from the mapping tables available
2372 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2373 encodings now include a mapping for the Apple logo)
2374
Tim Peterse3547fd2005-12-16 23:13:57 +00002375- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002376
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002377- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002378
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002379- A new AST parser implementation was completed. The abstract
2380 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002381 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002382
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002383- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002384 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2385
Neal Norwitz708e51a2005-10-03 04:48:15 +00002386- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2387
Neal Norwitz11bd1192005-10-03 00:54:56 +00002388- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2389 Provide a warning when a directory is passed on the command line.
2390
Neal Norwitz40d37812005-10-02 01:48:49 +00002391- Fix segfault with invalid coding.
2392
2393- SF bug #772896: unknown encoding results in MemoryError.
2394
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002395- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002396 supported a __len__() method which evaluated to False when the iterator
2397 was empty.
2398
Guido van Rossum630db602005-09-20 18:49:54 +00002399- On 64-bit platforms, when __len__() returns a value that cannot be
2400 represented as a C int, raise OverflowError.
2401
Skip Montanarof8948ca2005-09-19 03:54:46 +00002402- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002403 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002404
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002405- SF bug #893549: parsing keyword arguments was broken with a few format
2406 codes.
2407
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002408- Changes donated by Elemental Security to make it work on AIX 5.3
2409 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2410 bug #105470: test_pwd fails on 64bit system (Opteron).
2411
Guido van Rossum539c6622005-09-14 17:49:54 +00002412- Changes donated by Elemental Security to make it work on HP-UX 11 on
2413 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2414
Georg Brandl4550b8d2005-08-26 06:43:52 +00002415- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002416 (fixes bug #1119418).
2417
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002418- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2419
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002420- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2421 exceptions that cause a function to exit.
2422
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002423- The implementation of set() and frozenset() was revised to use its
2424 own internal data structure. Memory consumption is reduced by 1/3
2425 and there are modest speed-ups as well. The API is unchanged.
2426
Tim Petersde7990b2005-07-17 23:45:23 +00002427- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2428
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002429- SF bug #1229429: PyObject_CallMethod failed to decrement some
2430 reference counts in some error exit cases.
2431
Tim Petersecc6e6a2005-07-10 22:30:55 +00002432- SF bug #1185883: Python's small-object memory allocator took over
2433 a block managed by the platform C library whenever a realloc specified
2434 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002435 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002436 portable way to copy data from the C-managed block into Python's
2437 small-object space without risking a memory fault. Python's small-object
2438 realloc now leaves such blocks under the control of the platform C
2439 realloc.
2440
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002441- SF bug #1232517: An overflow error was not detected properly when
2442 attempting to convert a large float to an int in os.utime().
2443
Raymond Hettinger3296e692005-06-29 23:29:56 +00002444- SF bug #1224347: hex longs now print with lowercase letters just
2445 like their int counterparts.
2446
Michael W. Hudson188d4362005-06-20 16:52:57 +00002447- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2448 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2449 interpreter states; back out that fix and do a better job (see
2450 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2451 for a longer write-up of the problem).
2452
Michael W. Hudsondf888462005-06-03 14:41:55 +00002453- SF patch #1180995: marshal now uses a binary format by default when
2454 serializing floats.
2455
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002456- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2457 the routines that promise to produce IEEE 754 binary representations
2458 of floats now simply copy bytes around.
2459
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002460- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2461 278.
2462
Brett Cannonc3647ac2005-04-26 03:45:26 +00002463- patch #1109424: int, long, float, complex, and unicode now check for the
2464 proper magic slot for type conversions when subclassed. Previously the
2465 magic slot was ignored during conversion. Semantics now match the way
2466 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002467 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002468 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002469 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002470
Barry Warsawc8d907c2005-04-19 23:43:40 +00002471- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2472 NULL, now raise an AttributeError when attempting to set or delete the
2473 attribute. Previously a TypeError was raised, but this was inconsistent
2474 with the equivalent pure-Python implementation.
2475
Michael W. Hudson774479c2005-04-18 08:46:17 +00002476- It is now safe to call PyGILState_Release() before
2477 PyEval_InitThreads() (note that if there is reason to believe there
2478 are multiple threads around you still must call PyEval_InitThreads()
2479 before using the Python API; this fix is for extension modules that
2480 have no way of knowing if Python is multi-threaded yet).
2481
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002482- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2483 disabled caused a crash.
2484
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002485- Bug #1165306: instancemethod_new allowed the creation of a method
2486 with im_class == im_self == NULL, which caused a crash when called.
2487
Tim Petersecc6e6a2005-07-10 22:30:55 +00002488- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002489 fixes the crash seen in bug #1165761
2490
Raymond Hettinger96229b12005-03-11 06:49:40 +00002491- Added two new builtins, any() and all().
2492
Brett Cannon409d8f22005-03-05 06:47:57 +00002493- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002494 (e.g., ``class C(): pass`` is no longer a syntax error).
2495 Patch #1176012 added support to the 'parser' module and 'compiler' package
2496 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002497
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002498- Patch #1115086: Support PY_LONGLONG in structmember.
2499
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002500- Bug #1155938: new style classes did not check that __init__() was
2501 returning None.
2502
Tim Petersecc6e6a2005-07-10 22:30:55 +00002503- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002504 ('\') with a specific error message.
2505
Martin v. Löwisff232d72005-03-03 09:24:38 +00002506- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2507
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002508- Bug #1124295: the __name__ attribute of file objects was
2509 inadvertently made inaccessible in restricted mode.
2510
Tim Petersecc6e6a2005-07-10 22:30:55 +00002511- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002512 an ferror() call.
2513
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002514- min() and max() now support key= arguments with the same meaning as in
2515 list.sort().
2516
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002517- The peephole optimizer now performs simple constant folding in expressions:
2518 (2+3) --> (5).
2519
Raymond Hettingera422c342005-01-11 03:03:27 +00002520- set and frozenset objects can now be marshalled. SF #1098985.
2521
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002522- Bug #1077106: Poor argument checking could cause memory corruption
2523 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002524
Jeremy Hyltonab630502005-02-04 18:44:06 +00002525- The parser did not complain about future statements in illegal
2526 positions. It once again reports a syntax error if a future
2527 statement occurs after anything other than a doc string.
2528
Neil Schemenauercf52c072005-08-12 17:34:58 +00002529- Change the %s format specifier for str objects so that it returns a
2530 unicode instance if the argument is not an instance of basestring and
2531 calling __str__ on the argument returns a unicode instance.
2532
Tim Petersf4e69282006-02-27 17:15:31 +00002533- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2534 current thread state when the auto-GIL-state machinery knows about
2535 it (since the thread state is being deleted, continuing to remember it
2536 can't help, but can hurt if another thread happens to get created with
2537 the same thread id).
2538
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002539Extension Modules
2540-----------------
2541
Georg Brandl43f08a82006-03-31 18:01:16 +00002542- Patch #1380952: fix SSL objects timing out on consecutive read()s

2545
Anthony Baxterfa869072006-03-20 05:21:58 +00002546- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2547 In addition, the existing ulaw code was updated.
2548
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002549- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002550 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002551
Neal Norwitz10be10c2006-03-16 06:50:13 +00002552- Everything under lib-old was removed. This includes the following modules:
2553 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002554 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002555 util, whatsound, whrandom, zmod
2556
2557- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2558
2559- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002560 is deprecated. The undocumented re.engine variable no longer exists.
2561
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002562- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2563 SS2 (single-shift 2) escape sequences correctly.
2564
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002565- The unicodedata module was updated to the 4.1 version of the Unicode
2566 database. The 3.2 version is still available as unicodedata.db_3_2_0
2567 for applications that require this specific version (such as IDNA).
2568
Neal Norwitzb62c4332006-03-04 18:35:47 +00002569- The timing module is no longer built by default. It was deprecated
2570 in PEP 4 in Python 2.0 or earlier.
2571
Guido van Rossum1968ad32006-02-25 22:38:04 +00002572- Patch 1433928: Added a new type, defaultdict, to the collections module.
2573 This uses the new __missing__ hook behavior added to dict (see above).
2574
Georg Brandldbd83392006-02-20 09:42:33 +00002575- Bug #854823: socketmodule now builds on Sun platforms even when
2576 INET_ADDRSTRLEN is not defined.
2577
Georg Brandlf4f44152006-02-18 22:29:33 +00002578- Patch #1393157: os.startfile() now has an optional argument to specify
2579 a "command verb" to invoke on the file.
2580
Neal Norwitz082b2df2006-02-07 07:04:46 +00002581- Bug #876637, prevent stack corruption when socket descriptor
2582 is larger than FD_SETSIZE.
2583
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002584- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2585 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2586 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
2587
Martin v. Löwis57a34e82006-02-04 19:12:37 +00002588- Patch #1422385: The nis module now supports access to domains other
2589 than the system default domain.
2590
Martin v. Löwis14694662006-02-03 12:54:16 +00002591- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2592 are reported, the limit on path name lengths is removed, and stat reports
2593 WindowsError now (instead of OSError).
2594
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002595- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
2596

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002729- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2730 been renamed to have only a single underscore prefix. This was done to
2731 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002732
Nick Coghlan43832302006-04-23 17:04:07 +00002733- PEP 338: new module runpy defines a run_module function to support
2734 executing modules which provide access to source code or a code object
2735 via the PEP 302 import mechanisms.
2736

2745 in attribute values.
2746
Anthony Baxterc51ee692006-04-01 00:57:31 +00002747- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002748 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002749 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002750 module will not be built.
2751
Tim Petersc17976e2006-04-01 00:26:53 +00002752- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2753 aren't officially supported here, and trying to use them will probably
2754 raise an exception some day. But dicts have been allowed, and "mostly
2755 worked", so support for them won't go away without warning.
2756
Georg Brandl338ef7d2006-03-31 18:42:16 +00002757- Bug #1445068: getpass.getpass() can now be given an explicit stream

2775
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002776- email 4.0 package now integrated. This is largely the same as the email 3.0
2777 package that was included in Python 2.3, except that PEP 8 module names are
2778 now used (e.g. mail.message instead of email.Message). The MIME classes
2779 have been moved to a subpackage (e.g. email.mime.text instead of
2780 email.MIMEText). The old names are still supported for now. Several
2781 deprecated Message methods have been removed and lots of bugs have been
2782 fixed. More details can be found in the email package documentation.
2783
Walter Dörwald40108c92006-03-27 08:15:44 +00002784- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2785 (a subclass of tuple) that provides incremental decoders and encoders
2786 (a way to use stateful codecs without the stream API). Python functions
2787 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2788 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2789 have been added.

2792 a ValueError instead of a StopIteration now (like file and cString.String do).

Neal Norwitzab86f8e2005-12-23 21:44:36 +00002861- Patch #1157027: cookielib mishandles RFC 2109 cookies in Netscape mode
2862
Neal Norwitz338e7862005-12-23 21:27:46 +00002863- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2864 LoadError as documented, instead of IOError. For compatibility,
2865 LoadError subclasses IOError.
2866
Brett Cannon3cbd0382005-12-16 22:49:23 +00002867- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002868 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2869 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2870 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2871 Ronald L. Rivest offered this advice for Python:
2872
2873 "The consensus of researchers in this area (at least as
2874 expressed at the NIST Hash Function Workshop 10/31/05),
2875 is that SHA-256 is a good choice for the time being, but
2876 that research should continue, and other alternatives may
2877 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002878
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002879- Added a subset of Fredrik Lundh's ElementTree package. Available

2932 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002933 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002934

2956 to W3C name (404 -> 'Not Found'). RFE #1216944.
2957
Georg Brandl9e43acf2005-07-04 17:16:07 +00002958- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2959 as this can cause problems with apps closing all file descriptors.

2972 Bug #1224621.
2973
Raymond Hettinger68c04532005-06-10 11:05:19 +00002974- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002975 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002976 the generate_tokens() function now accepts a callable argument that
2977 terminates by raising StopIteration.
2978
Georg Brandl9166e1a2005-06-04 09:20:03 +00002979- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2987 class at all.
2988
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002989- distutils.commands.upload was added to support uploading distribution

2993 them to PyPI.
2994
Raymond Hettinger267b8682005-03-27 10:47:39 +00002995- decimal operator and comparison methods now return NotImplemented
2996 instead of raising a TypeError when interacting with other types. This
2997 allows other classes to implement __radd__ style methods and have them
2998 work as expected.
2999
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003000- Bug #1163325: Decimal infinities failed to hash. Attempting to
3001 hash a NaN raised an InvalidOperation instead of a TypeError.
3002
Tim Petersecc6e6a2005-07-10 22:30:55 +00003003- Patch #918101: Add tarfile open mode r|* for auto-detection of the

3037
Guido van Rossumd0641422005-02-03 15:01:24 +00003038- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3039 disables recursive traversal through instance attributes, which can
3040 be exploited in various ways.
3041
Tim Peterse3547fd2005-12-16 23:13:57 +00003042- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003043 flags on the HTTP listening socket.
3044

Thomas Hellerd6c6e222005-01-20 19:20:16 +00003053- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3054
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003055- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3056
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003057- Enhancements to the csv module:
3058
3059 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003060 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003061 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003062 + Dialect parameter parsing has been re-implemented to improve error
3063 reporting.
3064 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3065 dictates.
3066 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003067 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003068 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003069 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3070 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003071 + reader now allows \r characters to be quoted (previously it only allowed
3072 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003073 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003074 + Dialect classes passed to the module are no longer instantiated by
3075 the module before being parsed (the former validation scheme required
3076 this, but the mechanism was unreliable).
3077 + The dialect registry now contains instances of the internal
3078 C-coded dialect type, rather than references to python objects.
3079 + the internal c-coded dialect type is now immutable.
3080 + register_dialect now accepts the same keyword dialect specifications
3081 as the reader and writer, allowing the user to register dialects
3082 without first creating a dialect class.
3083 + a configurable limit to the size of parsed fields has been added -
3084 previously, an unmatched quote character could result in the entire
3085 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003086 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003087 the parser field size limit (returning the former limit). The initial
3088 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003089 + A line_num attribute has been added to the reader object, which tracks
3090 the number of lines read from the source iterator. This is not
3091 the same as the number of records returned, as records can span
3092 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003093 + reader and writer objects were not being registered with the cyclic-GC.
3094 This has been fixed.
3095
Brett Cannone6539c42005-01-08 02:43:53 +00003096- _DummyThread objects in the threading module now delete self.__block that is
3097 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3098 lock primitives tend to be limited in number and thus should not be wasted on
3099 a _DummyThread object. Fixes bug #1089632.
3100
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003101- The imghdr module now detects Exif files.
3102
Raymond Hettinger6065d322004-12-20 23:51:53 +00003103- StringIO.truncate() now correctly adjusts the size attribute.
3104 (Bug #951915).
3105
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003106- locale.py now uses an updated locale alias table (built using
3107 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3108 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003109 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003110
Raymond Hettinger3557f422004-12-07 12:02:02 +00003111- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3112
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003113- the pickle module no longer accepts the deprecated None option in the
3114 args tuple returned by __reduce__().
3115
Brett Cannon84667c02004-12-07 03:25:18 +00003116- optparse now optionally imports gettext. This allows its use in setup.py.
3117
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003118- the pickle module no longer uses the deprecated bin parameter.
3119
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003120- the shelve module no longer uses the deprecated binary parameter.
3121
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003122- the pstats module no longer uses the deprecated ignore() method.
3123
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003124- the filecmp module no longer uses the deprecated use_statcache argument.
3125
Raymond Hettinger664347b2004-12-04 21:21:53 +00003126- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3127 extended or overridden by subclasses. Formerly, the subclassed method would
3128 be ignored by the rest of the module. (Bug #1078905).
3129
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003130- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003131 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003132
Walter Dörwald36733692004-12-22 12:50:50 +00003133- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3134 once when a size argument is given. This prevents a buffer overflow in the
3135 tokenizer with very long source lines.
3136
Barry Warsaw538561e2006-01-01 21:48:54 +00003137- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3138 immediately after creating the object, without any intervening
3139 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003140
Skip Montanaro05885812005-01-16 20:48:27 +00003141- The reconvert.quote function can now emit triple-quoted strings. The
3142 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003143
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003144- ``UserString.MutableString`` now supports negative indices in
3145 ``__setitem__`` and ``__delitem__``
3146
Greg Ward40407942005-03-05 02:53:17 +00003147- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3148 correctly.
3149
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003150- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3151 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3152 character even if the user has passed a size parameter to get a proper
3153 line ending. Remove the special handling of a "\r\n" that has been split
3154 between two lines.
3155
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003156- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3157 about illegal code points. The codec now supports PEP 293 style error
3158 handlers.
3159
Walter Dörwald78a78b02005-09-01 12:04:29 +00003160- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003161 from the input stream, so that the output is a byte string in the correct
3162 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003163
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003164- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3165 considering it exactly like a '*'.
3166
Walter Dörwald007f8df2005-10-09 19:42:27 +00003167- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3168 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003169
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003170- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3171
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003172- Patch #1413711: Certain patterns of differences were making difflib
3173 touch the recursion limit.
3174
Walter Dörwald58917a62006-03-31 15:26:22 +00003175- Bug #947906: An object oriented interface has been added to the calendar
3176 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003177 called as a script (e.g. via ``python -mcalendar``). Localized month and
3178 weekday names can be ouput (even if an exotic encoding is used) using
3179 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003181Build
3182-----
3183
Neal Norwitz602d3392006-03-31 08:21:40 +00003184- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3185 by using -mieee gcc option.
3186

3188
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003189- Build support for Win64-AMD64 was added.
3190
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003191- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3192
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003193- Patch #881820: look for openpty and forkpty also in libbsd.
3194
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003195- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3196 The zlib module is now builtin on Windows.
3197
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003198- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3199
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003200- Bug #1189330: configure did not correctly determine the necessary
3201 value of LINKCC if python was built with GCC 4.0.
3202
Trent Mick8321b422005-07-26 02:29:21 +00003203- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3204 vulnerability in zlib 1.2.1 and 1.2.2.
3205
Brett Cannon08cd5982005-04-24 22:26:38 +00003206- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3207 flags that change binary compatibility. Changes were also made to
3208 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003209 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003210
Bob Ippolitoed233462005-03-29 13:47:59 +00003211- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3212 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3213 no longer exists). This configure patch makes things right.
3214
Martin v. Löwise2713be2005-03-08 15:03:08 +00003215- Bug #1158607: Build with --disable-unicode again.
3216
Brett Cannon46d96232005-02-16 00:07:19 +00003217- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3218 defined. Discovered as a result of not being able to build on OS X.
3219
Brett Cannon516592f2004-12-07 00:42:59 +00003220- setup.py now uses the directories specified in LDFLAGS using the -L option
3221 and in CPPFLAGS using the -I option for adding library and include
3222 directories, respectively, for compiling extension modules against. This has
3223 led to the core being compiled using the values in CPPFLAGS. It also removes
3224 the need for the special-casing of both DarwinPorts and Fink for darwin since
3225 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3226 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3227 Fink, ``-I/opt/local/include`` for DarwinPorts).
3228
Brett Cannon43802422005-02-10 20:48:03 +00003229- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3230 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3231 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3232 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003234C API
3235-----
3236
Tim Petersc9d78aa2006-03-26 23:27:58 +00003237- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3238 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3239 is obtained via the ``PyObject_`` family, it must be released via the
3240 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3241 always been officially true, but when Python's small-object allocator was
3242 introduced, an attempt was made to cater to a few extension modules
3243 discovered at the time that obtained memory via ``PyObject_New`` but
3244 released it via ``PyMem_DEL``. It's years later, and if such code still
3245 exists it will fail now (probably with segfaults, but calling wrong
3246 low-level memory management functions can yield many symptoms).
3247
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003248- Added a C API for set and frozenset objects.
3249
Raymond Hettinger66517482004-12-03 11:45:13 +00003250- Removed PyRange_New().
3251
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003252- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3253 mapping argument now. This string is used as a mapping table. Byte values
3254 greater than the length of the string and 0xFFFE are treated as undefined
3255 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00003261- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003262
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003263- Patch #1276356: New resource "urlfetch" is implemented. This enables
3264 even impatient people to run tests that require remote files.
