11
12Core and builtins
13-----------------
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000014
Amaury Forgeot d'Arcb50f9922008-09-26 22:46:01 +000015- Issue #3967: Fixed a crash in the count() and find() methods of string-like
16 objects, when the "start" parameter is a huge value.
17
Benjamin Petersond1c7d072008-09-25 20:46:05 +000018- Issue #3936: The parser warnings for using "as" and "with" as variable names
19 didn't fire after import statements.
20
Amaury Forgeot d'Arcafa0d582008-09-01 20:05:08 +000021- Issue #3751: str.rpartition would perform a left-partition when called with
22 a unicode argument.
23
Georg Brandl45c33ce2008-08-11 09:13:26 +000024- Issue #3537: Fix an assertion failure when an empty but presized dict
25 object was stored in the freelist.
26
Neal Norwitz4f3be8a2008-07-31 17:08:14 +000027- Apply security patches from Apple.
28
Neal Norwitz83ac0142008-07-28 05:06:20 +000029- Issue #2620: Overflow checking when allocating or reallocating memory
30 was not always being done properly in some python types and extension
31 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
32 all been updated to perform better checks and places in the code that
33 would previously leak memory on the error path when such an allocation
34 failed have been fixed.
35
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +000036- Issue #2242: Fix a crash when decoding invalid utf-7 input on certain
37 Windows / Visual Studio versions.
38
Mark Dickinsonab396e02008-07-16 11:04:17 +000039- Issue #3360: Fix incorrect parsing of '020000000000.0', which
40 produced a ValueError instead of giving the correct float.
41
Amaury Forgeot d'Arcceda6a62008-07-01 20:52:56 +000042- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
43 set to a custom object whose write() method happens to install
44 another file in sys.stdout.
45
Amaury Forgeot d'Arcb15bdf72008-07-01 20:59:49 +000046- Issue #3088: Corrected a race condition in classes derived from
47 threading.local: the first member set by a thread could be saved in
48 another thread's dictionary.
49
Amaury Forgeot d'Arc3255e132008-06-16 19:22:42 +000050- Issue #3100: Corrected a crash on deallocation of a subclassed weakref which
51 holds the last (strong) reference to its referent.
52
Guido van Rossumaa975432008-04-10 22:43:58 +000053- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
54 having a self-referential tuple, which is possible from C code. Nor did
55 object's tp_str consider that a type's tp_str could do something that could
56 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
57 respectively, fixed the issues. (Backport of r58288 from trunk.)
58
Georg Brandld9f1da02008-03-29 01:50:46 +000059- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
60 cannot be executed.
61
Amaury Forgeot d'Arc8432d862008-03-28 20:45:42 +000062- The compilation of a class nested in another class used to leak one
63 reference on the outer class name.
64
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000065- Issue #1477: With narrow Unicode builds, the unicode escape sequence
66 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
67 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
68 UTF-16 surrogates are generated in this case, like normal unicode literals
69 and the 'unicode-escape' codec.
70
Neal Norwitzb3635f92008-03-18 04:17:36 +000071- Issue #2321: use pymalloc for unicode object string data to reduce
72 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +000073
Sean Reifscheider4af861c2008-03-20 17:39:31 +000074- Issue #2238: Some syntax errors in *args and **kwargs expressions could give
75 bogus error messages.
76
Gregory P. Smith14acde32008-04-09 23:41:13 +000077- Issue #2587: In the C API, PyString_FromStringAndSize() takes a signed size
78 parameter but was not verifying that it was greater than zero. Values
79 less than zero will now raise a SystemError and return NULL to indicate a
80 bug in the calling C code.
81
Gregory P. Smith9aa040d2008-06-02 00:07:25 +000082- Issue #2588, #2589: Fix potential integer underflow and overflow
83 conditions in the PyOS_vsnprintf C API function.
84
Gregory P. Smithcae7f882008-09-07 06:44:12 +000085- Issue #1204: The configure script now tests for additional libraries
86 that may be required when linking against readline. This fixes issues
87 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
Georg Brandld9f1da02008-03-29 01:50:46 +000088
Gregory P. Smitha7a94a02008-09-22 00:22:44 +000089- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
90 library targets in the Makefile.

93-------
94
Brett Cannon70f1192d2008-09-29 03:57:24 +000095- Issue #3895: _lsprof could be crashed with an external timer that did not
96 return a float when a Profiler object is garbage collected.
97

101 sizes.
102
Hirokazu Yamamoto64773502008-09-04 14:26:56 +0000103- Issue #3762: platform.architecture() fails if python is lanched via
104 its symbolic link.
105
Thomas Heller275e2292008-08-19 17:17:37 +0000106- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
107 api functions without holding the GIL, which could lead to a fatal
108 error when they failed.
109
Amaury Forgeot d'Arc22679b82008-08-18 19:33:42 +0000110- Issue #2234: distutils failed for some versions of the cygwin compiler. The
111 version reported by these tools does not necessarily follow the python
112 version numbering scheme, so the module is less strict when parsing it.
113
Hirokazu Yamamoto1d63a452008-08-17 09:49:10 +0000114- Issue #2222: Fixed reference leak when occured os.rename()
115 fails unicode conversion on 2nd parameter. (windows only)
116
Georg Brandl1576bab2008-08-12 08:39:33 +0000117- Issue #3134: shutil referenced undefined WindowsError symbol.

123
Brett Cannonff931572008-07-13 01:20:19 +0000124- Issue #3339: dummy_thread.acquire() could return None which is not a valid
125 return value.
126

128
Thomas Hellerf3bb2832008-04-25 19:55:19 +0000129- Issue #2682: ctypes callback functions no longer contain a cyclic
130 reference to themselves.
131
Amaury Forgeot d'Arc8d904c32008-04-22 21:17:18 +0000132- Issue #2670: Fix a failure in urllib2.build_opener(), when passed two
133 handlers that derive the same default base class.
134
Amaury Forgeot d'Arc198e3532008-03-27 23:41:59 +0000135- Issue #2495: tokenize.untokenize now inserts a space between two consecutive
136 string literals; previously, ["" ""] was rendered as [""""], which is
137 incorrect python code.
138
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +0000139- Issue #2482: Make sure that the coefficient of a Decimal is always
140 stored as a str instance, not as a unicode instance. This ensures
141 that str(Decimal) is always an instance of str. This fixes a
142 regression from Python 2.5.1 to Python 2.5.2.
143
Mark Dickinson26c25d92008-03-25 14:35:25 +0000144- Issue #2478: fix failure of decimal.Decimal(0).sqrt()

155 root directory, and also exclude .hg, .git, .bzr, and _darcs.
156
Andrew M. Kuchling37d4f7b2008-02-23 19:06:54 +0000157- Bug #1389051: imaplib causes excessive memory fragmentation when reading

Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000161 calling .read() on a socket object wrapped with makefile().
Andrew M. Kuchling664553a2008-02-23 19:30:59 +0000162
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +0000163- Bug #1433694: minidom's .normalize() failed to set .nextSibling for

171 in the common case when the data is returned from the underlying socket
172 in increments much smaller than bignumber.
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +0000173
Gregory P. Smithb4bc9b92008-08-04 00:15:54 +0000174- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
175 argument in python 2.5, this broke code that subclassed Popen to include its

255-----------------
256
Martin v. Löwis73c01d42008-02-14 11:26:18 +0000257- Added checks for integer overflows, contributed by Google. Some are
258 only available if asserts are left in the code, in cases where they
259 can't be triggered from Python code.
260

Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000264- Issue #1920: "while 0" statements were completely removed by the compiler,
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000265 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000266 the condition is false. Now the compiler correctly emits bytecode for the
267 "else" suite.
268
Guido van Rossumd933e0a2008-01-24 18:28:37 +0000269- A few crashers fixed: weakref_in_del.py (issue #1377858);

295 format code incorrectly truncated the length to an int, even when
296 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
297 results with huge strings.
298
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000299- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arc30f61cb2007-11-24 13:53:29 +0000300 attribute of an empty cell object.

Neal Norwitzff4b63b2006-08-04 04:50:21 +00001223
1224Core and builtins
1225-----------------
1226
Neal Norwitz24b6f202006-09-05 04:43:56 +00001227- Fix infinite recursion when subclassing long and overriding __hash__.
1228
1229- Fix concatenation (+=) of long strings.
1230
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001231- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001232 compared equal or unequal to a string and a UnicodeDecodeError
1233 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001234
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001235 Instead, the equal (==) and unequal (!=) comparison operators will
1236 now issue a UnicodeWarning and interpret the two objects as
1237 unequal. The UnicodeWarning can be filtered as desired using
1238 the warning framework, e.g. silenced completely, turned into an
1239 exception, logged, etc.
1240
1241 Note that compare operators other than equal and unequal will still
1242 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001243
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001244- Fix segfault when doing string formatting on subclasses of long.
1245
1246- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1247 with new-style classes.
1248
1249- Fix bug related to __len__ functions returning negative values with
1250 classic classes.
1251
1252- Patch #1538606, Fix __index__() clipping. There were some problems
1253 discovered with the API and how integers that didn't fit into Py_ssize_t
1254 were handled. This patch attempts to provide enough alternatives
1255 to effectively use __index__.
1256
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001257- Bug #1536021: __hash__ may now return long int; the final hash
1258 value is obtained by invoking hash on the long int.
1259
Thomas Hellerab1049c2006-08-08 17:37:00 +00001260- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1261
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001262- Bug #1535165: fixed a segfault in input() and raw_input() when
1263 sys.stdin is closed.
1264
Thomas Heller74d36f02006-08-04 18:17:40 +00001265- On Windows, the PyErr_Warn function is now exported from
1266 the Python dll again.
1267
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001268- Bug #1191458: tracing over for loops now produces a line event
1269 on each iteration. Fixing this problem required changing the .pyc
1270 magic number. This means that .pyc files generated before 2.5c1
1271 will be regenerated.
1272
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001273- Bug #1333982: string/number constants were inappropriately stored
1274 in the byte code and co_consts even if they were not used, ie
1275 immediately popped off the stack.
1276
Georg Brandle9462c72006-08-04 18:03:37 +00001277- Fixed a reference-counting problem in property().

1280Library
1281-------
1282
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001283- Fix a bug in the ``compiler`` package that caused invalid code to be
1284 generated for generator expressions.
1285
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001286- The distutils version has been changed to 2.5.0. The change to
1287 keep it programmatically in sync with the Python version running
1288 the code (introduced in 2.5b3) has been reverted. It will continue
1289 to be maintained manually as static string literal.
1290
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001291- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001292 and this cannot be converted to the required C type, an exception is
1293 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001294 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001295
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001296- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001297 an exception.
1298
Tim Peterscbdd3502006-09-05 01:47:53 +00001299- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001300 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001301 workarounds for clocks with low resolution, to stop the code yielding
1302 duplicate UUIDs.
1303
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001304- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1305 before raising SystemExit, allowing IDLE to honor quit() and exit().
1306
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001307- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1308
Georg Brandl7a1af772006-08-14 21:55:28 +00001309- Patch #1536071: trace.py should now find the full module name of a
1310 file correctly even on Windows.
1311
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001312- logging's atexit hook now runs even if the rest of the module has
1313 already been cleaned up.
1314
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001315- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001316
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001317- Bug #1531405, format_exception no longer raises an exception if
1318 str(exception) raised an exception.
1319
Neil Schemenauer06ded092006-08-04 16:20:30 +00001320- Fix a bug in the ``compiler`` package that caused invalid code to be
1321 generated for nested functions.

1332 raises the correct exceptions.
1333
Thomas Heller1ce433e2006-08-14 16:20:04 +00001334- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1335 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1336
Thomas Heller86720042006-08-14 11:17:48 +00001337- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1338 uses the _as_parameter_ attribute when objects are passed to foreign
1339 function calls. The ctypes version number was changed to 1.0.1.
1340
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001341- Bug #1530559, struct.pack raises TypeError where it used to convert.
1342 Passing float arguments to struct.pack when integers are expected
1343 now triggers a DeprecationWarning.
1344

Neal Norwitza1f10902006-07-12 07:28:29 +00001390
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001391*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001392
1393Core and builtins
1394-----------------
1395
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001396- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001397 returned a long (see PEP 353).
1398
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001399- Bug #1515471: string.replace() accepts character buffers again.
1400
Neal Norwitz07aadb12006-07-30 06:55:48 +00001401- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1402 This provides the proper warning for struct.pack().
1403 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1404
Neal Norwitz0d62a062006-07-30 06:53:31 +00001405- Patch #1531113: Fix augmented assignment with yield expressions.
1406 Also fix a SystemError when trying to assign to yield expressions.
1407
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001408- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1409 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1410 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1411 excessive filesystem operations during imports.
1412
Tim Petersbc24eee2006-07-27 01:14:53 +00001413- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1414 operations on signed longs that are formally undefined by C.
1415 Unfortunately, at least one compiler now cares about that, so complicated
1416 the code to make that compiler happy again.
1417
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001418- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1419
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001420- Patch #1232023: Stop including current directory in search
1421 path on Windows.
1422
Neal Norwitze1fdb322006-07-21 05:32:28 +00001423- Fix some potential crashes found with failmalloc.
1424
Neal Norwitze7563102006-07-17 01:00:16 +00001425- Fix warnings reported by Klocwork's static analysis tool.
1426
Neal Norwitz84be93b2006-07-16 01:50:38 +00001427- Bug #1512814, Fix incorrect lineno's when code within a function
1428 had more than 255 blank lines.
1429
Georg Brandl9dceedb2006-07-12 15:31:17 +00001430- Patch #1521179: Python now accepts the standard options ``--help`` and
1431 ``--version`` as well as ``/?`` on Windows.
1432
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001433- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001434 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001435 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001436
Tim Peters112aad32006-07-19 00:03:19 +00001437- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001438 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001439 new ``sys._current_frames()`` returns a dictionary with one entry,
1440 mapping the faux "thread id" 0 to the current frame.
1441
Ronald Oussoren3075e162006-07-25 20:28:55 +00001442- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001443

1447
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001448- Correction of patch #1455898: In the mbcs decoder, set final=False
1449 for stream decoder, but final=True for the decode function.
1450
Georg Brandl07fec3a2006-08-01 18:49:24 +00001451- os.urandom no longer masks unrelated exceptions like SystemExit or
1452 KeyboardInterrupt.
1453
Tim Peters4643c2f2006-08-10 22:45:34 +00001454- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001455 shutil.copytree on Windows
1456
Georg Brandle34ac7c2006-07-30 11:07:23 +00001457- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1458 refers to file descriptors, not file objects.
1459
Tim Peterscbdd3502006-09-05 01:47:53 +00001460- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001461 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001462 #1513611, and probably others.
1463
Georg Brandledd9b0d2006-07-29 09:33:26 +00001464- Bug #1441397: The compiler module now recognizes module and function
1465 docstrings correctly as it did in Python 2.4.
1466
Tim Peters6f681472006-07-27 23:44:37 +00001467- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1468 lost that tests are sorted by name before being run. This rarely
1469 matters for well-written tests, but can create baffling symptoms if
1470 side effects from one test to the next affect outcomes. ``DocTestFinder``
1471 has been changed to sort the list of tests it returns.
1472
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001473- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001474 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001475
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001476- Bug #978833: Really close underlying socket in _socketobject.close.
1477
Georg Brandldb232dc2006-08-20 13:15:43 +00001478- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1479 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001480
Georg Brandlcf0c1722006-07-26 07:23:32 +00001481- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1482 to recursive calls and call it with the failing package name.
1483
Martin v. Löwis0b483032006-07-25 09:53:12 +00001484- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1485
Georg Brandlc13c34c2006-07-24 14:09:56 +00001486- Patch #1515343: Fix printing of deprecated string exceptions with a
1487 value in the traceback module.
1488
Greg Ward48fae7a2006-07-23 16:05:51 +00001489- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1490
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001491- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1492
Brett Cannoncaebe222006-07-18 04:41:36 +00001493- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1494 argument tuple. For arguments where zero is illegal, the value is forced to
1495 the minimum value that is correct. This is to support an undocumented but
1496 common way people used to fill in inconsequential information in the time
1497 tuple pre-2.4.
1498
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001499- Patch #1220874: Update the binhex module for Mach-O.
1500
Barry Warsawb110bad2006-07-21 14:51:07 +00001501- The email package has improved RFC 2231 support, specifically for
1502 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1503 (name*0=<blah>) parameter continuations. This may change the types of
1504 values returned from email.message.Message.get_param() and friends.
1505 Specifically in some cases where non-encoded continuations were used,
1506 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1507 will just return the string (since non-encoded continuations don't have
1508 charset and language parts).
1509
1510 Also, whereas % values were decoded in all parameter continuations, they are
1511 now only decoded in encoded parameter parts.
1512
Ronald Oussoren3075e162006-07-25 20:28:55 +00001513- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1514
1515- Bug #1517996: IDLE now longer shows the default Tk menu when a
1516 path browser, class browser or debugger is the frontmost window on MacOS X
1517
Barry Warsaw00decd72006-07-27 23:43:15 +00001518- Patch #1520294: Support for getset and member descriptors in types.py,
1519 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1520 of an object against these built-in types and more importantly, for getting
1521 their docstrings printed in the interactive interpreter's help() function.

1525-----------------
1526
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001527- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1528 a socket operation on a socket with a timeout, the exception will be
1529 caught correctly. Previously, the exception was not caught.
1530
Thomas Heller1393d6a2006-07-28 21:43:20 +00001531- Patch #1529514: The _ctypes extension is now compiled on more
1532 openbsd target platforms.
1533
Tim Peters9cab5932006-07-28 00:30:00 +00001534- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1535 a memory leak, affecting pickles and deep copies.
1536
Tim Petersbc24eee2006-07-27 01:14:53 +00001537- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001538 Paul Eggert.
1539
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001540- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1541
Thomas Hellerce049a02006-07-14 17:51:14 +00001542- Patch #1521817: Index range checking on ctypes arrays containing
1543 exactly one element enabled again. This allows iterating over these
1544 arrays, without the need to check the array size before.
1545
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001546- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001547 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001548 /dev/null in certain cases; this is now fixed.
1549
Thomas Heller47d7a062006-07-12 08:43:47 +00001550- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1551 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001552
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001553- Because of a misspelled preprocessor symbol, ctypes was always
1554 compiled without thread support; this is now fixed.
1555
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001556- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1557 methods now allow their database parameter to be None as the
1558 sleepycat API allows.
1559
Matt Flemingec926502006-07-28 11:27:27 +00001560- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1561 bluetooth API compared with Linux and FreeBSD.
1562
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001563Tests
1564-----
1565
1566- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1567 how long the test file should take to play. Now accepts taking 2.93 secs
1568 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1569
Georg Brandl4793aa32006-07-28 18:31:39 +00001570- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1571 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1572 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001579Mac
1580---
1581
1582- PythonLauncher now works correctly when the path to the script contains
1583 characters that are treated specially by the shell (such as quotes).
1584
1585- Bug #1527397: PythonLauncher now launches scripts with the working directory
1586 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001587 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001588 expect.

1597-----------------
1598
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001599- Bug #1441486: The literal representation of -(sys.maxint - 1)
1600 again evaluates to a int object, not a long.
1601
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001602- Bug #1501934: The scope of global variables that are locally assigned
1603 using augmented assignment is now correctly determined.
1604
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001605- Bug #927248: Recursive method-wrapper objects can now safely
1606 be released.
1607
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001608- Bug #1417699: Reject locale-specific decimal point in float()
1609 and atof().
1610
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001611- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1612 omit a default "error" argument for NULL pointer. This allows
1613 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001614
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001615- Bug #1519018: 'as' is now validated properly in import statements.
1616
Neal Norwitz28746ab2006-07-09 22:14:42 +00001617- On 64 bit systems, int literals that use less than 64 bits are
1618 now ints rather than longs.
1619
Neal Norwitzed657552006-07-10 00:04:44 +00001620- Bug #1512814, Fix incorrect lineno's when code at module scope
1621 started after line 256.
1622
Tim Peters32a83612006-07-10 21:08:24 +00001623- New function ``sys._current_frames()`` returns a dict mapping thread
1624 id to topmost thread stack frame. This is for expert use, and is
1625 especially useful for debugging application deadlocks. The functionality
1626 was previously available in Fazal Majid's ``threadframe`` extension
1627 module, but it wasn't possible to do this in a wholly threadsafe way from
1628 an extension.

Martin v. Löwis06c68b82006-07-10 22:11:28 +00001636- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1637

Martin v. Löwis8d656812006-07-10 07:23:48 +00001639 environment variable to be set in order to the SDK environment
1640 for finding the compiler, include files, etc.

1645
Thomas Woutersadd19112006-07-05 11:03:49 +00001646- string.Template() now correctly handles tuple-values. Previously,
1647 multi-value tuples would raise an exception and single-value tuples would
1648 be treated as the value they contain, instead.
1649
Martin v. Löwisede77f52006-07-03 13:01:35 +00001650- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1651 even if some data are received.
1652
Martin v. Löwis45482392006-07-03 12:28:58 +00001653- Bug #1267547: Put proper recursive setup.py call into the
1654 spec file generated by bdist_rpm.
1655
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001656- Bug #1514693: Update turtle's heading when switching between
1657 degrees and radians.
1658
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001659- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001660 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001661
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001662- Bug #1514703: Only setup canvas window in turtle when the canvas
1663 is created.
1664
Martin v. Löwis7596e832006-07-01 15:33:37 +00001665- Bug #1513223: .close() of a _socketobj now releases the underlying
1666 socket again, which then gets closed as it becomes unreferenced.
1667
Fred Drake10497c82006-06-29 02:57:48 +00001668- Bug #1504333: Make sgmllib support angle brackets in quoted
1669 attribute values.
1670
1671- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1672 sgmllib ('[' and ']' were not accepted).
1673
Georg Brandl1be63af2006-06-28 20:23:25 +00001674- Fix a bug in the turtle module's end_fill function.
1675
Brett Cannon53ab5b72006-06-22 16:49:14 +00001676- Bug #1510580: The 'warnings' module improperly required that a Warning
1677 category be either a types.ClassType and a subclass of Warning. The proper
1678 check is just that it is a subclass with Warning as the documentation states.
1679
Georg Brandlad29e632006-06-21 17:45:17 +00001680- The compiler module now correctly compiles the new try-except-finally
1681 statement (bug #1509132).
1682
Neal Norwitz60373cd2006-06-22 06:30:50 +00001683- The wsgiref package is now installed properly on Unix.
1684
Vinay Sajip28e57612006-07-01 10:45:20 +00001685- A bug was fixed in logging.config.fileConfig() which caused a crash on
1686 shutdown when fileConfig() was called multiple times.
1687
Gerhard Häring762fbd32006-07-02 17:48:30 +00001688- The sqlite3 module did cut off data from the SQLite database at the first
1689 null character before sending it to a custom converter. This has been fixed
1690 now.

1693-----------------
1694
Tim Peters112aad32006-07-19 00:03:19 +00001695- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1696 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1697 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001698
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001699- Assigning None to pointer type fields in ctypes structures possible
1700 overwrote the wrong fields, this is fixed now.
1701
1702- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1703 on non-Windows platforms.
1704
1705- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1706 integer or long, without range checking.
1707
1708- Patch #1517790: It is now possible to use custom objects in the ctypes
1709 foreign function argtypes sequence as long as they provide a from_param
1710 method, no longer is it required that the object is a ctypes type.
1711
1712- The '_ctypes' extension module now works when Python is configured
1713 with the --without-threads option.
1714
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001715- Bug #1513646: os.access on Windows now correctly determines write
1716 access, again.
1717
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001718- Bug #1512695: cPickle.loads could crash if it was interrupted with
1719 a KeyboardInterrupt.

Neal Norwitza12aa882006-07-06 06:45:08 +00001721- Bug #1296433: parsing XML with a non-default encoding and
1722 a CharacterDataHandler could crash the interpreter in pyexpat.
1723
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001724- Patch #1516912: improve Modules support for OpenVMS.

1730
Tim Peters32a83612006-07-10 21:08:24 +00001731- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001732 Previously, the slight difference could cause compilation errors of the
1733 'zlib' module on systems with more than one version of zlib.
1734
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001735- The MSI compileall step was fixed to also support a TARGETDIR
1736 with spaces in it.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001765
1766Core and builtins
1767-----------------
1768
Georg Brandla56b9152006-06-19 06:35:54 +00001769- Patch #1507676: Error messages returned by invalid abstract object operations
1770 (such as iterating over an integer) have been improved and now include the
1771 type of the offending object to help with debugging.
1772
Brett Cannonea3912b2006-06-13 21:46:41 +00001773- Bug #992017: A classic class that defined a __coerce__() method that returned
1774 its arguments swapped would infinitely recurse and segfault the interpreter.
1775
Neal Norwitz909eb122006-06-12 02:13:21 +00001776- Fix the socket tests so they can be run concurrently.
1777
Neal Norwitzb9845e72006-06-12 02:11:18 +00001778- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001779 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001780
Brett Cannon22565aa2006-06-09 22:31:23 +00001781- Bug #532646: object.__call__() will continue looking for the __call__
1782 attribute on objects until one without one is found. This leads to recursion
1783 when you take a class and set its __call__ attribute to an instance of the
1784 class. Originally fixed for classic classes, but this fix is for new-style.
1785 Removes the infinite_rec_3 crasher.
1786
Georg Brandl24250812006-06-09 18:45:48 +00001787- The string and unicode methods startswith() and endswith() now accept
1788 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1789
Brett Cannonde3b0522006-06-08 17:00:45 +00001790- Buffer objects, at the C level, never used the char buffer
1791 implementation even when the char buffer for the wrapped object was
1792 explicitly requested (originally returned the read or write buffer).
1793 Now a TypeError is raised if the char buffer is not present but is
1794 requested.
1795
Georg Brandlddbaa662006-06-04 21:56:52 +00001796- Patch #1346214: Statements like "if 0: suite" are now again optimized
1797 away like they were in Python 2.4.
1798
Georg Brandlb7c8f542006-05-27 12:30:25 +00001799- Builtin exceptions are now full-blown new-style classes instead of
1800 instances pretending to be classes, which speeds up exception handling
1801 by about 80% in comparison to 2.5a2.
1802
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001803- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1804 Unicode 4.1.
1805
Georg Brandlf4ef1162006-05-26 18:03:31 +00001806- Patch #921466: sys.path_importer_cache is now used to cache valid and
1807 invalid file paths for the built-in import machinery which leads to
1808 fewer open calls on startup.
1809
Tim Peters696cf432006-05-24 21:10:40 +00001810- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1811 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1812 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1813 the number of input digits (it was and remains linear-time for bases
1814 2, 4, 8, 16 and 32).
1815
Tim Petersb713ec22006-05-23 18:45:30 +00001816- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1817 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1818 an integer close to ``sys.maxint``. This was repaired by patch
1819 #1335972, which also gives a nice speedup.
1820
Richard Jonescebbefc2006-05-23 18:28:17 +00001821- Patch #1337051: reduced size of frame objects.
1822
1823- PyErr_NewException now accepts a tuple of base classes as its
1824 "base" parameter.
1825
Richard Jones7c88dcc2006-05-23 10:37:38 +00001826- Patch #876206: function call speedup by retaining allocated frame
1827 objects.
1828
Georg Brandl7b90e162006-05-18 07:01:27 +00001829- Bug #1462152: file() now checks more thoroughly for invalid mode
1830 strings and removes a possible "U" before passing the mode to the
1831 C library function.
1832
Neal Norwitz1004a532006-05-15 07:17:23 +00001833- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1834
Neal Norwitz373f0a72006-05-15 07:04:36 +00001835- Bug #1487966: Fix SystemError with conditional expression in assignment
1836
Martin v. Löwis879768d2006-05-11 13:28:43 +00001837- WindowsError now has two error code attributes: errno, which carries
1838 the error values from errno.h, and winerror, which carries the error
1839 values from winerror.h. Previous versions put the winerror.h values
1840 (from GetLastError()) into the errno attribute.
1841
Martin v. Löwis77736712006-05-04 05:51:03 +00001842- Patch #1475845: Raise IndentationError for unexpected indent.
1843
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001844- Patch #1479181: split open() and file() from being aliases for each other.
1845
Tim Peters44bd9862006-06-01 13:49:23 +00001846- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1847 methods were always silently ignored by dictionaries when comparing keys.
1848 They are now passed through (except when using the C API function
1849 ``PyDict_GetItem()``, whose semantics did not change).
1850
1851- Bug #1456209: In some obscure cases it was possible for a class with a
1852 custom ``__eq__()`` method to confuse dict internals when class instances
1853 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1854 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001856Extension Modules
1857-----------------
1858
Trent Mick960a3f82006-06-28 20:30:41 +00001859- Bug #1295808: expat symbols should be namespaced in pyexpat
1860
1861- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1862
Brett Cannon6ee7d012006-06-08 16:23:04 +00001863- Change binascii.hexlify to accept a read-only buffer instead of only a char
1864 buffer and actually follow its documentation.
1865
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001866- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1867
Nick Coghlanc649ec52006-05-29 12:43:05 +00001868- Patch #1478788 (modified version): The functional extension module has
1869 been renamed to _functools and a functools Python wrapper module added.
1870 This provides a home for additional function related utilities that are
1871 not specifically about functional programming. See PEP 309.
1872
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001873- Patch #1493701: performance enhancements for struct module.
1874
Georg Brandl378d5922006-05-17 14:26:50 +00001875- Patch #1490224: time.altzone is now set correctly on Cygwin.
1876
Georg Brandl8d3342b2006-05-16 07:38:27 +00001877- Patch #1435422: zlib's compress and decompress objects now have a
1878 copy() method.
1879
Andrew MacIntyre92913322006-06-13 15:04:24 +00001880- Patch #1454481: thread stack size is now tunable at runtime for thread
1881 enabled builds on Windows and systems with Posix threads support.
1882
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001883- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1884 (up to the system limit of 32K characters).
1885
1886- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1887 As a result, these functions now raise WindowsError instead of OSError.
1888
Tim Peters7a822da2006-05-25 21:50:17 +00001889- ``time.clock()`` on Win64 should use the high-performance Windows
1890 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1891 Windows platforms).
1892
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001893- Calling Tk_Init twice is refused if the first call failed as that
1894 may deadlock.
1895
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001896- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1897 accept it without potentially using an uninitialized pointer.
1898
1899- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1900 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1901 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001902
Gregory P. Smith372b5832006-06-05 18:48:21 +00001903- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001904 [pybsddb project SF patch number 1466734]
1905
Gregory P. Smith372b5832006-06-05 18:48:21 +00001906- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1907 parameter is supplied. [SF pybsddb bug #1477863]
1908
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001909- bsddb: the __len__ method of a DB object has been fixed to return correct
1910 results. It could previously incorrectly return 0 in some cases.
1911 Fixes SF bug 1493322 (pybsddb bug 1184012).
1912
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001913- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1914 aborts the db transaction safely when a modifier callback fails.
1915 Fixes SF python patch/bug #1408584.
1916
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001917- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001918 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001919 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1920 database calls that would previously deadlock. [SF python bug #775414]
1921
Vinay Sajip28e57612006-07-01 10:45:20 +00001922- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1928-------
1929
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001930- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1931 functions.
1932
Martin v. Löwis3798da02006-06-17 18:44:27 +00001933- Patch #812986: Update turtle output even if not tracing.
1934
Vinay Sajip28e57612006-07-01 10:45:20 +00001935- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001936 Tkinter.BaseWidget.
1937
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001938- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1939
Martin v. Löwis337487e2006-06-17 09:15:14 +00001940- Patch #763580: Add name and value arguments to Tkinter variable
1941 classes.
1942
Georg Brandl83cc0d02006-06-14 08:50:03 +00001943- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1944 mime.types file for determining MIME types.
1945
Georg Brandl2605ca82006-06-14 06:08:31 +00001946- Bug #1339007: Shelf objects now don't raise an exception in their
1947 __del__ method when initialization failed.
1948
Martin v. Löwisd8251432006-06-14 05:21:04 +00001949- Patch #1455898: The MBCS codec now supports the incremental mode for
1950 double-byte encodings.
1951
Tim Peters43898b42006-06-14 04:09:25 +00001952- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1953 guarantee that adjacent triples in the return list always describe
1954 non-adjacent blocks. Previously, a pair of matching blocks could end
1955 up being described by multiple adjacent triples that formed a partition
1956 of the matching pair.
1957
Greg Ward0e0c9f42006-06-11 16:24:11 +00001958- Bug #1498146: fix optparse to handle Unicode strings in option help,
1959 description, and epilog.
1960
Greg Wardd1c797e2006-06-11 14:42:41 +00001961- Bug #1366250: minor optparse documentation error.
1962
Greg Ward7f547402006-06-11 00:40:49 +00001963- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1964 clarify docs.
1965
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001966- The wsgiref package has been added to the standard library.
1967
Nick Coghlan676725d2006-06-08 13:54:49 +00001968- The functions update_wrapper() and wraps() have been added to the functools
1969 module. These make it easier to copy relevant metadata from the original
1970 function when writing wrapper functions.
1971
Tim Petersd6a9eef2006-06-05 01:48:21 +00001972- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1973 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001974
Martin v. Löwis3f767792006-06-04 19:36:28 +00001975- Patch #1359618: Speed up charmap encoder by using a trie structure
1976 for lookup.
1977
Tim Petersd609b1a2006-06-02 23:22:51 +00001978- The functions in the ``pprint`` module now sort dictionaries by key
1979 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1980 if and only if its display required more than one line, although that
1981 wasn't documented. The new behavior increases predictability; e.g.,
1982 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1983
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001984- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1985 (thanks for J. J. Lee).
1986
Georg Brandl2b330372006-05-28 20:23:12 +00001987- Patch #1496206: improve urllib2 handling of passwords with respect to
1988 default HTTP and HTTPS ports.
1989
George Yoshidaf3c65de2006-05-28 16:39:09 +00001990- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1991
Bob Ippolito7298f272006-05-23 18:43:47 +00001992- Patch #1281707: speed up gzip.readline.
1993
Georg Brandlb89316f2006-05-17 15:51:16 +00001994- Patch #1180296: Two new functions were added to the locale module:
1995 format_string() to get the effect of "format % items" but locale-aware,
1996 and currency() to format a monetary number with currency sign.
1997
Georg Brandle3a25832006-05-17 14:56:04 +00001998- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1999 and several features added, such as speed and geometry control.
2000
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002001- Patch #1488881: add support for external file objects in bz2 compressed
2002 tarfiles.
2003
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002004- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2005 stdout arguments, making it possible to redirect input and output
2006 for remote debugging.
2007
2008- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2009 a couple of issues, notably handling of long file names using the
2010 GNU LONGNAME extension.
2011
2012- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2013 new flag when ``name`` is already the name of an option flag.
2014
2015- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2016 package.
2017
2018- Patch #1472854: make the rlcompleter.Completer class usable on non-
2019 UNIX platforms.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002054What's New in Python 2.5 alpha 2?
2055=================================
2056
2057*Release date: 27-APR-2006*
2058
2059Core and builtins
2060-----------------
2061
Thomas Heller1b046642006-04-18 18:51:06 +00002062- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2063 by converting these apis from macros into exported functions again:
2064
2065 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2066 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2067 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2068 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2069 PyRun_String Py_CompileString
2070
Martin v. Löwis45294a92006-04-18 06:24:08 +00002071- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2072
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002073- All uses of PyStructSequence_InitType have been changed to initialize
2074 the type objects only once, even if the interpreter is initialized
2075 multiple times.
2076
Neal Norwitz61546162006-04-14 05:20:28 +00002077- Bug #1454485, array.array('u') could crash the interpreter. This was
2078 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2079 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2080
2081- Py_UNICODE is unsigned. It was always documented as unsigned, but
2082 due to a bug had a signed value in previous versions.
2083
Tim Peters3a5e8b12006-04-11 01:44:07 +00002084- Patch #837242: ``id()`` of any Python object always gives a positive
2085 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2086 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002087 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002088 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002089
Tim Peters3a5e8b12006-04-11 01:44:07 +00002090 def __hash__(self):
2091 return id(self) # WRONG
2092
2093 because a hash result must be a (short) Python int but it was always
2094 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002095 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002096 was always usable as a hash value before this patch. That's no longer
2097 necessarily so.
2098
2099- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002100 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002101 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002102 #1454844)
2103
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002104- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2105 involving generators that have paused outside of any ``try`` or ``with``
2106 blocks. (In 2.5a1, a paused generator that was part of a reference
2107 cycle could not be garbage collected, regardless of whether it was
2108 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00002109
Anthony Baxter51bcb682006-04-05 14:51:42 +00002110Extension Modules

2112
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00002113- Patch #1191065: Fix preprocessor problems on systems where recvfrom
2114 is a macro.
2115
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002116- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2117 fails with an error condition.
2118
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002119- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2120
2121- Bug #1117761: bsddb.*open() no longer raises an exception when using
2122 the cachesize parameter.
2123
2124- Bug #1149413: bsddb.*open() no longer raises an exception when using
2125 a temporary db (file=None) with the 'n' flag to truncate on open.
2126
2127- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2128 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002129
Armin Rigoa9017c32006-04-19 11:50:27 +00002130- Patch #1062014: AF_UNIX sockets under Linux have a special
2131 abstract namespace that is now fully supported.
2132
Anthony Baxter51bcb682006-04-05 14:51:42 +00002133Library
2134-------
2135
Peter Astrand7d1d4362006-07-14 14:04:45 +00002136- Bug #1223937: subprocess.CalledProcessError reports the exit status
2137 of the process using the returncode attribute, instead of
2138 abusing errno.
2139
Tim Peters711bf302006-04-25 03:31:36 +00002140- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2141 a doctest to be skipped (the code is not run, and the expected output
2142 or exception is ignored).
2143
Nick Coghlanda2268f2006-04-24 04:37:15 +00002144- Fixed contextlib.nested to cope with exceptions being raised and
2145 caught inside exit handlers.
2146
Greg Wardab05edc2006-04-23 03:47:58 +00002147- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2148 hex, octal, or binary; add ``append_const`` action; keep going if
2149 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2150 added ``epilog`` for better help generation).
2151
Tim Peters21fbd572006-04-21 21:18:10 +00002152- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2153 called from a thread spawned as a side effect of importing a module.
2154
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002155- The pydoc module now supports documenting packages contained in
2156 .zip or .egg files.
2157
2158- The pkgutil module now has several new utility functions, such
2159 as ``walk_packages()`` to support working with packages that are either
2160 in the filesystem or zip files.
2161
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002162- The mailbox module can now modify and delete messages from
2163 mailboxes, in addition to simply reading them. Thanks to Gregory
2164 K. Johnson for writing the code, and to the 2005 Google Summer of
2165 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002166
Tim Petersc7605f22006-04-17 21:12:33 +00002167- The ``__del__`` method of class ``local`` in module ``_threading_local``
2168 returned before accomplishing any of its intended cleanup.
2169
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002170- Patch #790710: Add breakpoint command lists in pdb.
2171
Martin v. Löwis0db2a982006-04-16 20:55:38 +00002172- Patch #1063914: Add Tkinter.Misc.clipboard_get().
2173
Martin v. Löwis4b501e62006-04-15 08:41:11 +00002174- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
2175
Anthony Baxtere29002c2006-04-12 12:07:31 +00002176- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2177 Windows. Bug #1469163.
2178
Phillip J. Eby47032112006-04-11 01:07:43 +00002179- The warnings, linecache, inspect, traceback, site, and doctest modules
2180 were updated to work correctly with modules imported from zipfiles or
2181 via other PEP 302 __loader__ objects.
2182
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002183- Patch #1467770: Reduce usage of subprocess._active to processes which
2184 the application hasn't waited on.
2185
Martin v. Löwisb04dee92006-04-10 08:34:21 +00002186- Patch #1462222: Fix Tix.Grid.
2187
Neal Norwitza31bf182006-04-09 03:35:43 +00002188- Fix exception when doing glob.glob('anything*/')
2189
Skip Montanaro262fb922006-04-21 02:31:07 +00002190- The pstats.Stats class accepts an optional stream keyword argument to
2191 direct output to an alternate file-like object.
2192
Anthony Baxter51bcb682006-04-05 14:51:42 +00002193Build
2194-----
2195
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002196- The Makefile now has a reindent target, which runs reindent.py on
2197 the library.
2198
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002199- Patch #1470875: Building Python with MS Free Compiler
2200
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002201- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002202
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002203- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2204 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002205 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002206 CXX from --with-cxx-main, see description in README.
2207
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002208- Patch #1429775: Link extension modules with the shared libpython.
2209
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002210- Fixed a libffi build problem on MIPS systems.
2211
Tim Peters8931ff12006-05-13 23:28:20 +00002212- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2213 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2214 and "%zu" for unsigned integers of type ``size_t``.
2215
Anthony Baxter51bcb682006-04-05 14:51:42 +00002216Tests
2217-----
2218
Nick Coghlanda2268f2006-04-24 04:37:15 +00002219- test_contextlib now checks contextlib.nested can cope with exceptions
2220 being raised and caught inside exit handlers.
2221
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002222- test_cmd_line now checks operation of the -m and -c command switches
2223
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002224- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2225 it separately and by hand. It also wasn't cleaning up its changes to
2226 the current Decimal context.
2227
Thomas Woutersabd08882006-04-26 15:53:30 +00002228- regrtest.py now has a -M option to run tests that test the new limits of
2229 containers, on 64-bit architectures. Running these tests is only sensible
2230 on 64-bit machines with more than two gigabytes of memory. The argument
2231 passed is the maximum amount of memory for the tests to use.
2232
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00002233Tools

2235
2236- Added the Python benchmark suite pybench to the Tools/ directory;
2237 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002239Documentation
2240-------------
2241
Tim Petersb06d28c2006-05-12 01:57:59 +00002242- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2243
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002244- PEP 343: Added Context Types section to the library reference
2245 and attempted to bring other PEP 343 related documentation into
2246 line with the implementation and/or python-dev discussions.
2247
Tim Peters8dc73d22006-04-24 02:03:16 +00002248- Bug #1337990: clarified that ``doctest`` does not support examples
2249 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002252What's New in Python 2.5 alpha 1?
2253=================================
2254
Anthony Baxterebed3f62006-04-03 15:03:44 +00002255*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002256
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002257Core and builtins
2258-----------------
2259
Nick Coghlan43832302006-04-23 17:04:07 +00002260- PEP 338: -m command line switch now delegates to runpy.run_module
2261 allowing it to support modules in packages and zipfiles
2262
Martin v. Löwisc661b882006-04-20 04:54:23 +00002263- On Windows, .DLL is not an accepted file name extension for
2264 extension modules anymore; extensions are only found if they
2265 end in .PYD.
2266
Martin v. Löwisea62d252006-04-03 10:56:49 +00002267- Bug #1421664: sys.stderr.encoding is now set to the same value as
2268 sys.stdout.encoding.
2269
Neal Norwitz92e212f2006-04-03 04:48:37 +00002270- __import__ accepts keyword arguments.
2271
Georg Brandlccadf842006-03-31 18:54:53 +00002272- Patch #1460496: round() now accepts keyword arguments.
2273
Anthony Baxter262c00a2006-03-30 10:53:17 +00002274- Fixed bug #1459029 - unicode reprs were double-escaped.
2275
Hye-Shik Changd478f342006-03-23 12:32:36 +00002276- Patch #1396919: The system scope threads are reenabled on FreeBSD
2277 5.4 and later versions.
2278
Neal Norwitze98ccf62006-03-23 05:39:47 +00002279- Bug #1115379: Compiling a Unicode string with an encoding declaration
2280 now gives a SyntaxError.
2281
Georg Brandlabd1ff82006-03-18 07:59:59 +00002282- Previously, Python code had no easy way to access the contents of a
2283 cell object. Now, a ``cell_contents`` attribute has been added
2284 (closes patch #1170323).
2285
Tim Peterscf79aac2006-03-16 01:14:46 +00002286- Patch #1123430: Python's small-object allocator now returns an arena to
2287 the system ``free()`` when all memory within an arena becomes unused
2288 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2289 freed. Some applications will see a drop in virtual memory size now,
2290 especially long-running applications that, from time to time, temporarily
2291 use a large number of small objects. Note that when Python returns an
2292 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002293 platform C library will in turn return that memory to the operating system.
2294 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002295 appears to be effective at least on Microsoft C and gcc-based systems.
2296 Thanks to Evan Jones for hard work and patience.
2297
Georg Brandl533ff6f2006-03-08 18:09:27 +00002298- Patch #1434038: property() now uses the getter's docstring if there is
2299 no "doc" argument given. This makes it possible to legitimately use
2300 property() as a decorator to produce a read-only property.
2301
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002302- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2303 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2304 of requiring an int or long in slicing and a few other contexts, enabling
2305 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2306
Neal Norwitz995acdf2006-03-07 05:01:00 +00002307- Fixed various bugs reported by Coverity's Prevent tool.
2308
Brett Cannonbf364092006-03-01 04:25:17 +00002309- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2310 new exception base class, BaseException, which has a new message attribute.
2311 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2312 Raising a string exception now raises a DeprecationWarning.
2313
Thomas Woutersfb609f42006-02-28 16:37:25 +00002314- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2315 explicitly relative, using 'from .module import name' to mean 'from the same
2316 package as this module is in. Imports without dots still default to the
2317 old relative-then-absolute, unless 'from __future__ import
2318 absolute_import' is used.
2319
Brett Cannona7446e32006-02-27 23:39:10 +00002320- Properly check if 'warnings' raises an exception (usually when a filter set
2321 to "error" is triggered) when raising a warning for raising string
2322 exceptions.
2323
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002324- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002325 The name was removed from Include/code.h.
2326
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002327- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002328
Guido van Rossum1968ad32006-02-25 22:38:04 +00002329- Patch 1433928:
2330 - The copy module now "copies" function objects (as atomic objects).
2331 - dict.__getitem__ now looks for a __missing__ hook before raising
2332 KeyError.
2333
Tim Peters84ef21c2006-02-28 20:39:06 +00002334- PEP 343: with statement implemented. Needs ``from __future__ import
2335 with_statement``. Use of 'with' as a variable will generate a warning.
2336 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002337 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002338 The following objects have __context__ methods:
2339 - The built-in file type.
2340 - The thread.LockType type.
2341 - The following types defined by the threading module:
2342 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2343 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002344
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002345- Fix the encodings package codec search function to only search
2346 inside its own package. Fixes problem reported in patch #1433198.
2347
2348 Note: Codec packages should implement and register their own
2349 codec search function. PEP 100 has the details.
2350
Tim Peters9ea89d22006-06-04 03:26:02 +00002351- PEP 353: Using ``Py_ssize_t`` as the index type.
2352
2353- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2354 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2355 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2356 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2357 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002358
Neal Norwitzfc76d632006-01-10 06:03:13 +00002359- Patch #1400181, fix unicode string formatting to not use the locale.
2360 This is how string objects work. u'%f' could use , instead of .
2361 for the decimal point. Now both strings and unicode always use periods.
2362
Neal Norwitz671b9e32006-01-09 07:07:12 +00002363- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2364 configure would break checking curses.h.
2365
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002366- Bug #959576: The pwd module is now builtin. This allows Python to be
2367 built on UNIX platforms without $HOME set.
2368
Neal Norwitzc10978f2005-12-19 06:07:16 +00002369- Bug #1072182, fix some potential problems if characters are signed.
2370
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002371- Bug #889500, fix line number on SyntaxWarning for global declarations.
2372
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002373- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2374
Neal Norwitze7214a12005-12-18 05:03:17 +00002375- Support for converting hex strings to floats no longer works.
2376 This was not portable. float('0x3') now raises a ValueError.
2377
Barry Warsaw2a38a862005-12-18 01:27:35 +00002378- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002379 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002380 is now displayed in interactive prompt banner.
2381
Georg Brandlfa166682005-12-17 21:45:17 +00002382- Implementation of PEP 341 - Unification of try/except and try/finally.
2383 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002384 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002385
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002386- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2387 now encodes backslash correctly.
2388
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002389- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2390
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002391- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002392 and long longs.
2393
Neal Norwitz67715f02005-11-09 06:59:35 +00002394- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002395 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002396 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002397
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002398- Replaced most Unicode charmap codecs with new ones using the
2399 new Unicode translate string feature in the builtin charmap
2400 codec; the codecs were created from the mapping tables available
2401 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2402 encodings now include a mapping for the Apple logo)
2403
Tim Peterse3547fd2005-12-16 23:13:57 +00002404- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002405
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002406- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002407
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002408- A new AST parser implementation was completed. The abstract
2409 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002410 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002411
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002412- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002413 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2414
Neal Norwitz708e51a2005-10-03 04:48:15 +00002415- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2416
Neal Norwitz11bd1192005-10-03 00:54:56 +00002417- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2418 Provide a warning when a directory is passed on the command line.
2419
Neal Norwitz40d37812005-10-02 01:48:49 +00002420- Fix segfault with invalid coding.
2421
2422- SF bug #772896: unknown encoding results in MemoryError.
2423
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002424- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002425 supported a __len__() method which evaluated to False when the iterator
2426 was empty.
2427
Guido van Rossum630db602005-09-20 18:49:54 +00002428- On 64-bit platforms, when __len__() returns a value that cannot be
2429 represented as a C int, raise OverflowError.
2430
Skip Montanarof8948ca2005-09-19 03:54:46 +00002431- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002432 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002433
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002434- SF bug #893549: parsing keyword arguments was broken with a few format
2435 codes.
2436
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002437- Changes donated by Elemental Security to make it work on AIX 5.3
2438 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2439 bug #105470: test_pwd fails on 64bit system (Opteron).
2440
Guido van Rossum539c6622005-09-14 17:49:54 +00002441- Changes donated by Elemental Security to make it work on HP-UX 11 on
2442 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2443
Georg Brandl4550b8d2005-08-26 06:43:52 +00002444- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002445 (fixes bug #1119418).
2446
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002447- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2448
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002449- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2450 exceptions that cause a function to exit.
2451
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002452- The implementation of set() and frozenset() was revised to use its
2453 own internal data structure. Memory consumption is reduced by 1/3
2454 and there are modest speed-ups as well. The API is unchanged.
2455
Tim Petersde7990b2005-07-17 23:45:23 +00002456- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2457
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002458- SF bug #1229429: PyObject_CallMethod failed to decrement some
2459 reference counts in some error exit cases.
2460
Tim Petersecc6e6a2005-07-10 22:30:55 +00002461- SF bug #1185883: Python's small-object memory allocator took over
2462 a block managed by the platform C library whenever a realloc specified
2463 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002464 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002465 portable way to copy data from the C-managed block into Python's
2466 small-object space without risking a memory fault. Python's small-object
2467 realloc now leaves such blocks under the control of the platform C
2468 realloc.
2469
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002470- SF bug #1232517: An overflow error was not detected properly when
2471 attempting to convert a large float to an int in os.utime().
2472
Raymond Hettinger3296e692005-06-29 23:29:56 +00002473- SF bug #1224347: hex longs now print with lowercase letters just
2474 like their int counterparts.
2475
Michael W. Hudson188d4362005-06-20 16:52:57 +00002476- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2477 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2478 interpreter states; back out that fix and do a better job (see
2479 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2480 for a longer write-up of the problem).
2481
Michael W. Hudsondf888462005-06-03 14:41:55 +00002482- SF patch #1180995: marshal now uses a binary format by default when
2483 serializing floats.
2484
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002485- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2486 the routines that promise to produce IEEE 754 binary representations
2487 of floats now simply copy bytes around.
2488
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002489- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2490 278.
2491
Brett Cannonc3647ac2005-04-26 03:45:26 +00002492- patch #1109424: int, long, float, complex, and unicode now check for the
2493 proper magic slot for type conversions when subclassed. Previously the
2494 magic slot was ignored during conversion. Semantics now match the way
2495 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002496 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002497 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002498 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002499
Barry Warsawc8d907c2005-04-19 23:43:40 +00002500- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2501 NULL, now raise an AttributeError when attempting to set or delete the
2502 attribute. Previously a TypeError was raised, but this was inconsistent
2503 with the equivalent pure-Python implementation.
2504
Michael W. Hudson774479c2005-04-18 08:46:17 +00002505- It is now safe to call PyGILState_Release() before
2506 PyEval_InitThreads() (note that if there is reason to believe there
2507 are multiple threads around you still must call PyEval_InitThreads()
2508 before using the Python API; this fix is for extension modules that
2509 have no way of knowing if Python is multi-threaded yet).
2510
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002511- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2512 disabled caused a crash.
2513
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002514- Bug #1165306: instancemethod_new allowed the creation of a method
2515 with im_class == im_self == NULL, which caused a crash when called.
2516
Tim Petersecc6e6a2005-07-10 22:30:55 +00002517- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002518 fixes the crash seen in bug #1165761
2519
Raymond Hettinger96229b12005-03-11 06:49:40 +00002520- Added two new builtins, any() and all().
2521
Brett Cannon409d8f22005-03-05 06:47:57 +00002522- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002523 (e.g., ``class C(): pass`` is no longer a syntax error).
2524 Patch #1176012 added support to the 'parser' module and 'compiler' package
2525 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002526
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002527- Patch #1115086: Support PY_LONGLONG in structmember.
2528
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002529- Bug #1155938: new style classes did not check that __init__() was
2530 returning None.
2531
Tim Petersecc6e6a2005-07-10 22:30:55 +00002532- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002533 ('\') with a specific error message.
2534
Martin v. Löwisff232d72005-03-03 09:24:38 +00002535- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2536
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002537- Bug #1124295: the __name__ attribute of file objects was
2538 inadvertently made inaccessible in restricted mode.
2539
Tim Petersecc6e6a2005-07-10 22:30:55 +00002540- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002541 an ferror() call.
2542
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002543- min() and max() now support key= arguments with the same meaning as in
2544 list.sort().
2545
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002546- The peephole optimizer now performs simple constant folding in expressions:
2547 (2+3) --> (5).
2548
Raymond Hettingera422c342005-01-11 03:03:27 +00002549- set and frozenset objects can now be marshalled. SF #1098985.
2550
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002551- Bug #1077106: Poor argument checking could cause memory corruption
2552 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002553
Jeremy Hyltonab630502005-02-04 18:44:06 +00002554- The parser did not complain about future statements in illegal
2555 positions. It once again reports a syntax error if a future
2556 statement occurs after anything other than a doc string.
2557
Neil Schemenauercf52c072005-08-12 17:34:58 +00002558- Change the %s format specifier for str objects so that it returns a
2559 unicode instance if the argument is not an instance of basestring and
2560 calling __str__ on the argument returns a unicode instance.
2561
Tim Petersf4e69282006-02-27 17:15:31 +00002562- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2563 current thread state when the auto-GIL-state machinery knows about
2564 it (since the thread state is being deleted, continuing to remember it
2565 can't help, but can hurt if another thread happens to get created with
2566 the same thread id).
2567
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002568Extension Modules
2569-----------------
2570
Georg Brandl43f08a82006-03-31 18:01:16 +00002571- Patch #1380952: fix SSL objects timing out on consecutive read()s
2572
Neal Norwitz05a45592006-03-20 06:30:08 +00002573- Patch #1309579: wait3 and wait4 were added to the posix module.
2574
Anthony Baxterfa869072006-03-20 05:21:58 +00002575- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2576 In addition, the existing ulaw code was updated.
2577
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002578- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002579 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002580
Neal Norwitz10be10c2006-03-16 06:50:13 +00002581- Everything under lib-old was removed. This includes the following modules:
2582 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002583 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002584 util, whatsound, whrandom, zmod
2585
2586- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2587
2588- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002589 is deprecated. The undocumented re.engine variable no longer exists.
2590
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002591- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2592 SS2 (single-shift 2) escape sequences correctly.
2593
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002594- The unicodedata module was updated to the 4.1 version of the Unicode
2595 database. The 3.2 version is still available as unicodedata.db_3_2_0
2596 for applications that require this specific version (such as IDNA).
2597
Neal Norwitzb62c4332006-03-04 18:35:47 +00002598- The timing module is no longer built by default. It was deprecated

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002758- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2759 been renamed to have only a single underscore prefix. This was done to
2760 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002761
Nick Coghlan43832302006-04-23 17:04:07 +00002762- PEP 338: new module runpy defines a run_module function to support
2763 executing modules which provide access to source code or a code object
2764 via the PEP 302 import mechanisms.
2765
Anthony Baxter93f5b932006-04-03 08:05:07 +00002766- The email module's parsedate_tz function now sets the daylight savings

2774 in attribute values.
2775
Anthony Baxterc51ee692006-04-01 00:57:31 +00002776- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002777 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002778 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002779 module will not be built.
2780
Tim Petersc17976e2006-04-01 00:26:53 +00002781- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2782 aren't officially supported here, and trying to use them will probably
2783 raise an exception some day. But dicts have been allowed, and "mostly
2784 worked", so support for them won't go away without warning.
2785
Georg Brandl338ef7d2006-03-31 18:42:16 +00002786- Bug #1445068: getpass.getpass() can now be given an explicit stream
2787 argument to specify where to write the prompt.
2788

2804
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002805- email 4.0 package now integrated. This is largely the same as the email 3.0
2806 package that was included in Python 2.3, except that PEP 8 module names are
2807 now used (e.g. mail.message instead of email.Message). The MIME classes
2808 have been moved to a subpackage (e.g. email.mime.text instead of
2809 email.MIMEText). The old names are still supported for now. Several
2810 deprecated Message methods have been removed and lots of bugs have been
2811 fixed. More details can be found in the email package documentation.
2812
Walter Dörwald40108c92006-03-27 08:15:44 +00002813- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2814 (a subclass of tuple) that provides incremental decoders and encoders
2815 (a way to use stateful codecs without the stream API). Python functions
2816 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2817 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2818 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002819
Walter Dörwald067db482006-03-15 22:17:27 +00002820- Patch #1359365: Calling next() on a closed StringIO.String object raises
2821 a ValueError instead of a StopIteration now (like file and cString.String do).
2822 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2823 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002824
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002825- A regrtest option -w was added to re-run failed tests in verbose mode.

Tim Petersda1329b2006-02-27 16:50:01 +00002872- Patch #1349118: urllib now supports user:pass@ style proxy
Martin v. Löwis3e865952006-01-24 15:51:21 +00002873 specifications, raises IOErrors when proxies for unsupported protocols
2874 are defined, and uses the https proxy on https redirections.

2891
Neal Norwitz338e7862005-12-23 21:27:46 +00002892- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2893 LoadError as documented, instead of IOError. For compatibility,
2894 LoadError subclasses IOError.
2895
Brett Cannon3cbd0382005-12-16 22:49:23 +00002896- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002897 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2898 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2899 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2900 Ronald L. Rivest offered this advice for Python:
2901
2902 "The consensus of researchers in this area (at least as
2903 expressed at the NIST Hash Function Workshop 10/31/05),
2904 is that SHA-256 is a good choice for the time being, but
2905 that research should continue, and other alternatives may
2906 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002907
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002908- Added a subset of Fredrik Lundh's ElementTree package. Available

2961 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002962 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002963

3001 Bug #1224621.
3002
Raymond Hettinger68c04532005-06-10 11:05:19 +00003003- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00003004 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00003005 the generate_tokens() function now accepts a callable argument that
3006 terminates by raising StopIteration.
3007
Georg Brandl9166e1a2005-06-04 09:20:03 +00003008- Bug #1196315: fix weakref.WeakValueDictionary constructor.

3025 instead of raising a TypeError when interacting with other types. This
3026 allows other classes to implement __radd__ style methods and have them
3027 work as expected.
3028
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003029- Bug #1163325: Decimal infinities failed to hash. Attempting to

Guido van Rossumd0641422005-02-03 15:01:24 +00003067- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3068 disables recursive traversal through instance attributes, which can
3069 be exploited in various ways.
3070
Tim Peterse3547fd2005-12-16 23:13:57 +00003071- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003072 flags on the HTTP listening socket.
3073

3083
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003084- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3085
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003086- Enhancements to the csv module:
3087
3088 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003089 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003090 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003091 + Dialect parameter parsing has been re-implemented to improve error
3092 reporting.
3093 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3094 dictates.
3095 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003096 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003097 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003098 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3099 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003100 + reader now allows \r characters to be quoted (previously it only allowed
3101 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003102 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003103 + Dialect classes passed to the module are no longer instantiated by
3104 the module before being parsed (the former validation scheme required
3105 this, but the mechanism was unreliable).
3106 + The dialect registry now contains instances of the internal
3107 C-coded dialect type, rather than references to python objects.
3108 + the internal c-coded dialect type is now immutable.
3109 + register_dialect now accepts the same keyword dialect specifications
3110 as the reader and writer, allowing the user to register dialects
3111 without first creating a dialect class.
3112 + a configurable limit to the size of parsed fields has been added -
3113 previously, an unmatched quote character could result in the entire
3114 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003115 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003116 the parser field size limit (returning the former limit). The initial
3117 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003118 + A line_num attribute has been added to the reader object, which tracks
3119 the number of lines read from the source iterator. This is not
3120 the same as the number of records returned, as records can span
3121 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003122 + reader and writer objects were not being registered with the cyclic-GC.
3123 This has been fixed.
3124
Brett Cannone6539c42005-01-08 02:43:53 +00003125- _DummyThread objects in the threading module now delete self.__block that is
3126 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3127 lock primitives tend to be limited in number and thus should not be wasted on
3128 a _DummyThread object. Fixes bug #1089632.
3129
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003130- The imghdr module now detects Exif files.
3131
Raymond Hettinger6065d322004-12-20 23:51:53 +00003132- StringIO.truncate() now correctly adjusts the size attribute.
3133 (Bug #951915).
3134
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003135- locale.py now uses an updated locale alias table (built using
3136 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3137 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003138 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003139
Raymond Hettinger3557f422004-12-07 12:02:02 +00003140- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3141
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003142- the pickle module no longer accepts the deprecated None option in the
3143 args tuple returned by __reduce__().
3144
Brett Cannon84667c02004-12-07 03:25:18 +00003145- optparse now optionally imports gettext. This allows its use in setup.py.
3146
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003147- the pickle module no longer uses the deprecated bin parameter.
3148
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003149- the shelve module no longer uses the deprecated binary parameter.
3150
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003151- the pstats module no longer uses the deprecated ignore() method.
3152
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003153- the filecmp module no longer uses the deprecated use_statcache argument.
3154
Raymond Hettinger664347b2004-12-04 21:21:53 +00003155- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3156 extended or overridden by subclasses. Formerly, the subclassed method would
3157 be ignored by the rest of the module. (Bug #1078905).
3158
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003159- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003160 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003161
Walter Dörwald36733692004-12-22 12:50:50 +00003162- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3163 once when a size argument is given. This prevents a buffer overflow in the
3164 tokenizer with very long source lines.
3165
Barry Warsaw538561e2006-01-01 21:48:54 +00003166- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3167 immediately after creating the object, without any intervening
3168 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003169
Skip Montanaro05885812005-01-16 20:48:27 +00003170- The reconvert.quote function can now emit triple-quoted strings. The
3171 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003172
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003173- ``UserString.MutableString`` now supports negative indices in
3174 ``__setitem__`` and ``__delitem__``
3175
Greg Ward40407942005-03-05 02:53:17 +00003176- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3177 correctly.
3178
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003179- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3180 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3181 character even if the user has passed a size parameter to get a proper
3182 line ending. Remove the special handling of a "\r\n" that has been split
3183 between two lines.
3184
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003185- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3186 about illegal code points. The codec now supports PEP 293 style error
3187 handlers.
3188
Walter Dörwald78a78b02005-09-01 12:04:29 +00003189- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003190 from the input stream, so that the output is a byte string in the correct
3191 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003192
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003193- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3194 considering it exactly like a '*'.
3195
Walter Dörwald007f8df2005-10-09 19:42:27 +00003196- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3197 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003198
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003199- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3200
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003201- Patch #1413711: Certain patterns of differences were making difflib
3202 touch the recursion limit.
3203
Walter Dörwald58917a62006-03-31 15:26:22 +00003204- Bug #947906: An object oriented interface has been added to the calendar
3205 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003206 called as a script (e.g. via ``python -mcalendar``). Localized month and
3207 weekday names can be ouput (even if an exotic encoding is used) using
3208 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003209

3211-----
3212
Neal Norwitz602d3392006-03-31 08:21:40 +00003213- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3214 by using -mieee gcc option.
3215
Martin v. Löwis86d66262006-02-17 08:40:11 +00003216- Patch #1432345: Make python compile on DragonFly.
3217
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003218- Build support for Win64-AMD64 was added.
3219
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003220- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3221
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003222- Patch #881820: look for openpty and forkpty also in libbsd.
3223
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003224- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3225 The zlib module is now builtin on Windows.
3226
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003227- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3228
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003229- Bug #1189330: configure did not correctly determine the necessary
3230 value of LINKCC if python was built with GCC 4.0.
3231
Trent Mick8321b422005-07-26 02:29:21 +00003232- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3233 vulnerability in zlib 1.2.1 and 1.2.2.
3234
Brett Cannon08cd5982005-04-24 22:26:38 +00003235- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3236 flags that change binary compatibility. Changes were also made to
3237 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003238 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003239
Bob Ippolitoed233462005-03-29 13:47:59 +00003240- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3241 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3242 no longer exists). This configure patch makes things right.
3243
Martin v. Löwise2713be2005-03-08 15:03:08 +00003244- Bug #1158607: Build with --disable-unicode again.
3245
Brett Cannon46d96232005-02-16 00:07:19 +00003246- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3247 defined. Discovered as a result of not being able to build on OS X.
3248
Brett Cannon516592f2004-12-07 00:42:59 +00003249- setup.py now uses the directories specified in LDFLAGS using the -L option
3250 and in CPPFLAGS using the -I option for adding library and include
3251 directories, respectively, for compiling extension modules against. This has
3252 led to the core being compiled using the values in CPPFLAGS. It also removes
3253 the need for the special-casing of both DarwinPorts and Fink for darwin since
3254 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3255 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3256 Fink, ``-I/opt/local/include`` for DarwinPorts).
3257
Brett Cannon43802422005-02-10 20:48:03 +00003258- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3259 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3260 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3261 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003263C API
3264-----
3265
Tim Petersc9d78aa2006-03-26 23:27:58 +00003266- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3267 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3268 is obtained via the ``PyObject_`` family, it must be released via the
3269 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3270 always been officially true, but when Python's small-object allocator was
3271 introduced, an attempt was made to cater to a few extension modules
3272 discovered at the time that obtained memory via ``PyObject_New`` but
3273 released it via ``PyMem_DEL``. It's years later, and if such code still
3274 exists it will fail now (probably with segfaults, but calling wrong
3275 low-level memory management functions can yield many symptoms).
3276
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003277- Added a C API for set and frozenset objects.
3278
Raymond Hettinger66517482004-12-03 11:45:13 +00003279- Removed PyRange_New().
3280
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003281- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3282 mapping argument now. This string is used as a mapping table. Byte values
3283 greater than the length of the string and 0xFFFE are treated as undefined
3284 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003291
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003292- Patch #1276356: New resource "urlfetch" is implemented. This enables
