11
12Core and builtins
13-----------------
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000014
Benjamin Petersond1c7d072008-09-25 20:46:05 +000015- Issue #3936: The parser warnings for using "as" and "with" as variable names
16 didn't fire after import statements.
17
Amaury Forgeot d'Arcafa0d582008-09-01 20:05:08 +000018- Issue #3751: str.rpartition would perform a left-partition when called with
19 a unicode argument.
20
Georg Brandl45c33ce2008-08-11 09:13:26 +000021- Issue #3537: Fix an assertion failure when an empty but presized dict
22 object was stored in the freelist.
23
Neal Norwitz4f3be8a2008-07-31 17:08:14 +000024- Apply security patches from Apple.
25
Neal Norwitz83ac0142008-07-28 05:06:20 +000026- Issue #2620: Overflow checking when allocating or reallocating memory
27 was not always being done properly in some python types and extension
28 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
29 all been updated to perform better checks and places in the code that
30 would previously leak memory on the error path when such an allocation
31 failed have been fixed.
32
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +000033- Issue #2242: Fix a crash when decoding invalid utf-7 input on certain
34 Windows / Visual Studio versions.
35
Mark Dickinsonab396e02008-07-16 11:04:17 +000036- Issue #3360: Fix incorrect parsing of '020000000000.0', which
37 produced a ValueError instead of giving the correct float.
38
Amaury Forgeot d'Arcceda6a62008-07-01 20:52:56 +000039- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
40 set to a custom object whose write() method happens to install
41 another file in sys.stdout.
42
Amaury Forgeot d'Arcb15bdf72008-07-01 20:59:49 +000043- Issue #3088: Corrected a race condition in classes derived from
44 threading.local: the first member set by a thread could be saved in
45 another thread's dictionary.
46
Amaury Forgeot d'Arc3255e132008-06-16 19:22:42 +000047- Issue #3100: Corrected a crash on deallocation of a subclassed weakref which
48 holds the last (strong) reference to its referent.
49
Guido van Rossumaa975432008-04-10 22:43:58 +000050- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
51 having a self-referential tuple, which is possible from C code. Nor did
52 object's tp_str consider that a type's tp_str could do something that could
53 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
54 respectively, fixed the issues. (Backport of r58288 from trunk.)
55
Georg Brandld9f1da02008-03-29 01:50:46 +000056- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
57 cannot be executed.
58
Amaury Forgeot d'Arc8432d862008-03-28 20:45:42 +000059- The compilation of a class nested in another class used to leak one
60 reference on the outer class name.
61
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000062- Issue #1477: With narrow Unicode builds, the unicode escape sequence
63 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
64 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
65 UTF-16 surrogates are generated in this case, like normal unicode literals
66 and the 'unicode-escape' codec.
67
Neal Norwitzb3635f92008-03-18 04:17:36 +000068- Issue #2321: use pymalloc for unicode object string data to reduce
69 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +000070
Sean Reifscheider4af861c2008-03-20 17:39:31 +000071- Issue #2238: Some syntax errors in *args and **kwargs expressions could give
72 bogus error messages.
73
Gregory P. Smith14acde32008-04-09 23:41:13 +000074- Issue #2587: In the C API, PyString_FromStringAndSize() takes a signed size
75 parameter but was not verifying that it was greater than zero. Values
76 less than zero will now raise a SystemError and return NULL to indicate a
77 bug in the calling C code.
78
Gregory P. Smith9aa040d2008-06-02 00:07:25 +000079- Issue #2588, #2589: Fix potential integer underflow and overflow
80 conditions in the PyOS_vsnprintf C API function.
81
Gregory P. Smithcae7f882008-09-07 06:44:12 +000082- Issue #1204: The configure script now tests for additional libraries
83 that may be required when linking against readline. This fixes issues
84 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
Georg Brandld9f1da02008-03-29 01:50:46 +000085
Gregory P. Smitha7a94a02008-09-22 00:22:44 +000086- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
87 library targets in the Makefile.

96 its symbolic link.
97
Thomas Heller275e2292008-08-19 17:17:37 +000098- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
99 api functions without holding the GIL, which could lead to a fatal
100 error when they failed.
101
Amaury Forgeot d'Arc22679b82008-08-18 19:33:42 +0000102- Issue #2234: distutils failed for some versions of the cygwin compiler. The
103 version reported by these tools does not necessarily follow the python
104 version numbering scheme, so the module is less strict when parsing it.
105
Hirokazu Yamamoto1d63a452008-08-17 09:49:10 +0000106- Issue #2222: Fixed reference leak when occured os.rename()
107 fails unicode conversion on 2nd parameter. (windows only)
108

118
Raymond Hettinger75ee9eb2008-06-16 01:49:18 +0000119- Issue #3116 and #1792: Fix quadratic behavior in marshal.dumps().
120
Thomas Hellerf3bb2832008-04-25 19:55:19 +0000121- Issue #2682: ctypes callback functions no longer contain a cyclic
122 reference to themselves.

125 handlers that derive the same default base class.
126
Amaury Forgeot d'Arc198e3532008-03-27 23:41:59 +0000127- Issue #2495: tokenize.untokenize now inserts a space between two consecutive
128 string literals; previously, ["" ""] was rendered as [""""], which is
129 incorrect python code.
130
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +0000131- Issue #2482: Make sure that the coefficient of a Decimal is always
132 stored as a str instance, not as a unicode instance. This ensures
133 that str(Decimal) is always an instance of str. This fixes a
134 regression from Python 2.5.1 to Python 2.5.2.
135
Mark Dickinson26c25d92008-03-25 14:35:25 +0000136- Issue #2478: fix failure of decimal.Decimal(0).sqrt()

147 root directory, and also exclude .hg, .git, .bzr, and _darcs.
148
Andrew M. Kuchling37d4f7b2008-02-23 19:06:54 +0000149- Bug #1389051: imaplib causes excessive memory fragmentation when reading
150 large messages.

Andrew M. Kuchling05a19a52008-02-23 17:21:44 +0000155- Bug #1433694: minidom's .normalize() failed to set .nextSibling for
156 last child element.
157
Gregory P. Smith26660402008-06-01 23:44:46 +0000158- Issue #2791: subprocess.Popen.communicate explicitly closes its
159 stdout and stderr fds rather than leaving them open until the
160 instance is destroyed.

Gregory P. Smithf8f30fa2008-07-06 04:04:07 +0000162- Issue #2632: Prevent socket.read(bignumber) from over allocating memory
163 in the common case when the data is returned from the underlying socket
164 in increments much smaller than bignumber.
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +0000165
Gregory P. Smithb4bc9b92008-08-04 00:15:54 +0000166- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
167 argument in python 2.5, this broke code that subclassed Popen to include its
168 own poll method. Fixed my moving _deadstate to an _internal_poll method.
169
Gregory P. Smith7641b1c2008-08-04 03:23:25 +0000170- Issue #2113: Fix error in subprocess.Popen if the select system call is
171 interrupted by a signal.

247-----------------
248
Martin v. Löwis73c01d42008-02-14 11:26:18 +0000249- Added checks for integer overflows, contributed by Google. Some are

255
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000256- Issue #1920: "while 0" statements were completely removed by the compiler,
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000257 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000258 the condition is false. Now the compiler correctly emits bytecode for the
259 "else" suite.
260
Guido van Rossumd933e0a2008-01-24 18:28:37 +0000261- A few crashers fixed: weakref_in_del.py (issue #1377858);

Guido van Rossumc69ac252006-08-10 18:09:25 +00001211What's New in Python 2.5 release candidate 1?
1212=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001213
Anthony Baxterb4096662006-08-16 03:42:26 +00001214*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001215
1216Core and builtins
1217-----------------
1218
Neal Norwitz24b6f202006-09-05 04:43:56 +00001219- Fix infinite recursion when subclassing long and overriding __hash__.
1220
1221- Fix concatenation (+=) of long strings.
1222
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001223- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001224 compared equal or unequal to a string and a UnicodeDecodeError
1225 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001226
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001227 Instead, the equal (==) and unequal (!=) comparison operators will
1228 now issue a UnicodeWarning and interpret the two objects as
1229 unequal. The UnicodeWarning can be filtered as desired using
1230 the warning framework, e.g. silenced completely, turned into an
1231 exception, logged, etc.
1232
1233 Note that compare operators other than equal and unequal will still
1234 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001235
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001236- Fix segfault when doing string formatting on subclasses of long.
1237
1238- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1239 with new-style classes.
1240
1241- Fix bug related to __len__ functions returning negative values with
1242 classic classes.
1243
1244- Patch #1538606, Fix __index__() clipping. There were some problems
1245 discovered with the API and how integers that didn't fit into Py_ssize_t
1246 were handled. This patch attempts to provide enough alternatives
1247 to effectively use __index__.
1248
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001249- Bug #1536021: __hash__ may now return long int; the final hash
1250 value is obtained by invoking hash on the long int.
1251
Thomas Hellerab1049c2006-08-08 17:37:00 +00001252- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1253
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001254- Bug #1535165: fixed a segfault in input() and raw_input() when
1255 sys.stdin is closed.
1256
Thomas Heller74d36f02006-08-04 18:17:40 +00001257- On Windows, the PyErr_Warn function is now exported from
1258 the Python dll again.
1259
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001260- Bug #1191458: tracing over for loops now produces a line event
1261 on each iteration. Fixing this problem required changing the .pyc
1262 magic number. This means that .pyc files generated before 2.5c1
1263 will be regenerated.
1264
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001265- Bug #1333982: string/number constants were inappropriately stored
1266 in the byte code and co_consts even if they were not used, ie
1267 immediately popped off the stack.
1268
Georg Brandle9462c72006-08-04 18:03:37 +00001269- Fixed a reference-counting problem in property().
1270

1272Library
1273-------
1274
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001275- Fix a bug in the ``compiler`` package that caused invalid code to be
1276 generated for generator expressions.
1277
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001278- The distutils version has been changed to 2.5.0. The change to
1279 keep it programmatically in sync with the Python version running
1280 the code (introduced in 2.5b3) has been reverted. It will continue
1281 to be maintained manually as static string literal.
1282
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001283- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001284 and this cannot be converted to the required C type, an exception is
1285 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001286 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001287
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001288- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001289 an exception.
1290
Tim Peterscbdd3502006-09-05 01:47:53 +00001291- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001292 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001293 workarounds for clocks with low resolution, to stop the code yielding
1294 duplicate UUIDs.
1295
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001296- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1297 before raising SystemExit, allowing IDLE to honor quit() and exit().
1298
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001299- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1300
Georg Brandl7a1af772006-08-14 21:55:28 +00001301- Patch #1536071: trace.py should now find the full module name of a
1302 file correctly even on Windows.
1303
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001304- logging's atexit hook now runs even if the rest of the module has
1305 already been cleaned up.
1306
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001307- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001308
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001309- Bug #1531405, format_exception no longer raises an exception if
1310 str(exception) raised an exception.
1311
Neil Schemenauer06ded092006-08-04 16:20:30 +00001312- Fix a bug in the ``compiler`` package that caused invalid code to be
1313 generated for nested functions.

1324 raises the correct exceptions.
1325
Thomas Heller1ce433e2006-08-14 16:20:04 +00001326- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1327 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1328
Thomas Heller86720042006-08-14 11:17:48 +00001329- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1330 uses the _as_parameter_ attribute when objects are passed to foreign
1331 function calls. The ctypes version number was changed to 1.0.1.
1332
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001333- Bug #1530559, struct.pack raises TypeError where it used to convert.
1334 Passing float arguments to struct.pack when integers are expected
1335 now triggers a DeprecationWarning.

Fred Drake53912162006-07-29 13:22:49 +00001380What's New in Python 2.5 beta 3?
1381================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001382
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001383*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001384
1385Core and builtins
1386-----------------
1387
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001388- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001389 returned a long (see PEP 353).
1390
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001391- Bug #1515471: string.replace() accepts character buffers again.
1392
Neal Norwitz07aadb12006-07-30 06:55:48 +00001393- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1394 This provides the proper warning for struct.pack().
1395 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1396
Neal Norwitz0d62a062006-07-30 06:53:31 +00001397- Patch #1531113: Fix augmented assignment with yield expressions.
1398 Also fix a SystemError when trying to assign to yield expressions.
1399
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001400- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1401 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1402 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1403 excessive filesystem operations during imports.
1404
Tim Petersbc24eee2006-07-27 01:14:53 +00001405- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1406 operations on signed longs that are formally undefined by C.
1407 Unfortunately, at least one compiler now cares about that, so complicated
1408 the code to make that compiler happy again.
1409
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001410- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1411
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001412- Patch #1232023: Stop including current directory in search
1413 path on Windows.
1414
Neal Norwitze1fdb322006-07-21 05:32:28 +00001415- Fix some potential crashes found with failmalloc.
1416
Neal Norwitze7563102006-07-17 01:00:16 +00001417- Fix warnings reported by Klocwork's static analysis tool.
1418
Neal Norwitz84be93b2006-07-16 01:50:38 +00001419- Bug #1512814, Fix incorrect lineno's when code within a function
1420 had more than 255 blank lines.
1421
Georg Brandl9dceedb2006-07-12 15:31:17 +00001422- Patch #1521179: Python now accepts the standard options ``--help`` and
1423 ``--version`` as well as ``/?`` on Windows.
1424
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001425- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001426 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001427 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001428
Tim Peters112aad32006-07-19 00:03:19 +00001429- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001430 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001431 new ``sys._current_frames()`` returns a dictionary with one entry,
1432 mapping the faux "thread id" 0 to the current frame.
1433
Ronald Oussoren3075e162006-07-25 20:28:55 +00001434- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001435

1439
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001440- Correction of patch #1455898: In the mbcs decoder, set final=False
1441 for stream decoder, but final=True for the decode function.
1442
Georg Brandl07fec3a2006-08-01 18:49:24 +00001443- os.urandom no longer masks unrelated exceptions like SystemExit or
1444 KeyboardInterrupt.
1445
Tim Peters4643c2f2006-08-10 22:45:34 +00001446- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001447 shutil.copytree on Windows
1448
Georg Brandle34ac7c2006-07-30 11:07:23 +00001449- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1450 refers to file descriptors, not file objects.

Tim Peterscbdd3502006-09-05 01:47:53 +00001452- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001453 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001454 #1513611, and probably others.
1455
Georg Brandledd9b0d2006-07-29 09:33:26 +00001456- Bug #1441397: The compiler module now recognizes module and function
1457 docstrings correctly as it did in Python 2.4.
1458
Tim Peters6f681472006-07-27 23:44:37 +00001459- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1460 lost that tests are sorted by name before being run. This rarely
1461 matters for well-written tests, but can create baffling symptoms if
1462 side effects from one test to the next affect outcomes. ``DocTestFinder``
1463 has been changed to sort the list of tests it returns.
1464
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001465- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001466 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001467
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001468- Bug #978833: Really close underlying socket in _socketobject.close.
1469
Georg Brandldb232dc2006-08-20 13:15:43 +00001470- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1471 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001472
Georg Brandlcf0c1722006-07-26 07:23:32 +00001473- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1474 to recursive calls and call it with the failing package name.
1475
Martin v. Löwis0b483032006-07-25 09:53:12 +00001476- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1477
Georg Brandlc13c34c2006-07-24 14:09:56 +00001478- Patch #1515343: Fix printing of deprecated string exceptions with a
1479 value in the traceback module.
1480
Greg Ward48fae7a2006-07-23 16:05:51 +00001481- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1482
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001483- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1484
Brett Cannoncaebe222006-07-18 04:41:36 +00001485- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1486 argument tuple. For arguments where zero is illegal, the value is forced to
1487 the minimum value that is correct. This is to support an undocumented but
1488 common way people used to fill in inconsequential information in the time
1489 tuple pre-2.4.
1490
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001491- Patch #1220874: Update the binhex module for Mach-O.
1492
Barry Warsawb110bad2006-07-21 14:51:07 +00001493- The email package has improved RFC 2231 support, specifically for
1494 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1495 (name*0=<blah>) parameter continuations. This may change the types of
1496 values returned from email.message.Message.get_param() and friends.
1497 Specifically in some cases where non-encoded continuations were used,
1498 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1499 will just return the string (since non-encoded continuations don't have
1500 charset and language parts).
1501
1502 Also, whereas % values were decoded in all parameter continuations, they are
1503 now only decoded in encoded parameter parts.
1504
Ronald Oussoren3075e162006-07-25 20:28:55 +00001505- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1506
1507- Bug #1517996: IDLE now longer shows the default Tk menu when a
1508 path browser, class browser or debugger is the frontmost window on MacOS X
1509
Barry Warsaw00decd72006-07-27 23:43:15 +00001510- Patch #1520294: Support for getset and member descriptors in types.py,
1511 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1512 of an object against these built-in types and more importantly, for getting
1513 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001516Extension Modules
1517-----------------
1518
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001519- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1520 a socket operation on a socket with a timeout, the exception will be
1521 caught correctly. Previously, the exception was not caught.
1522
Thomas Heller1393d6a2006-07-28 21:43:20 +00001523- Patch #1529514: The _ctypes extension is now compiled on more
1524 openbsd target platforms.
1525
Tim Peters9cab5932006-07-28 00:30:00 +00001526- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1527 a memory leak, affecting pickles and deep copies.
1528
Tim Petersbc24eee2006-07-27 01:14:53 +00001529- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001530 Paul Eggert.
1531
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001532- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1533
Thomas Hellerce049a02006-07-14 17:51:14 +00001534- Patch #1521817: Index range checking on ctypes arrays containing
1535 exactly one element enabled again. This allows iterating over these
1536 arrays, without the need to check the array size before.
1537
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001538- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001539 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001540 /dev/null in certain cases; this is now fixed.
1541
Thomas Heller47d7a062006-07-12 08:43:47 +00001542- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1543 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001544
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001545- Because of a misspelled preprocessor symbol, ctypes was always
1546 compiled without thread support; this is now fixed.
1547
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001548- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1549 methods now allow their database parameter to be None as the
1550 sleepycat API allows.
1551
Matt Flemingec926502006-07-28 11:27:27 +00001552- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1553 bluetooth API compared with Linux and FreeBSD.
1554
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001555Tests
1556-----
1557
1558- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1559 how long the test file should take to play. Now accepts taking 2.93 secs
1560 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1561
Georg Brandl4793aa32006-07-28 18:31:39 +00001562- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1563 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1564 run via ``regrtest.py``. Now they do.

1567-----
1568
1569- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1570
Ronald Oussoren26cad082006-08-01 21:00:57 +00001571Mac
1572---
1573
1574- PythonLauncher now works correctly when the path to the script contains
1575 characters that are treated specially by the shell (such as quotes).
1576
1577- Bug #1527397: PythonLauncher now launches scripts with the working directory
1578 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001579 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001580 expect.

1589-----------------
1590
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001591- Bug #1441486: The literal representation of -(sys.maxint - 1)
1592 again evaluates to a int object, not a long.
1593
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001594- Bug #1501934: The scope of global variables that are locally assigned
1595 using augmented assignment is now correctly determined.
1596
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001597- Bug #927248: Recursive method-wrapper objects can now safely
1598 be released.
1599
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001600- Bug #1417699: Reject locale-specific decimal point in float()
1601 and atof().
1602
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001603- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1604 omit a default "error" argument for NULL pointer. This allows
1605 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001606
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001607- Bug #1519018: 'as' is now validated properly in import statements.
1608
Neal Norwitz28746ab2006-07-09 22:14:42 +00001609- On 64 bit systems, int literals that use less than 64 bits are
1610 now ints rather than longs.
1611
Neal Norwitzed657552006-07-10 00:04:44 +00001612- Bug #1512814, Fix incorrect lineno's when code at module scope
1613 started after line 256.
1614
Tim Peters32a83612006-07-10 21:08:24 +00001615- New function ``sys._current_frames()`` returns a dict mapping thread
1616 id to topmost thread stack frame. This is for expert use, and is
1617 especially useful for debugging application deadlocks. The functionality
1618 was previously available in Fazal Majid's ``threadframe`` extension
1619 module, but it wasn't possible to do this in a wholly threadsafe way from
1620 an extension.
1621

1637
Thomas Woutersadd19112006-07-05 11:03:49 +00001638- string.Template() now correctly handles tuple-values. Previously,
1639 multi-value tuples would raise an exception and single-value tuples would
1640 be treated as the value they contain, instead.
1641
Martin v. Löwisede77f52006-07-03 13:01:35 +00001642- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1643 even if some data are received.
1644
Martin v. Löwis45482392006-07-03 12:28:58 +00001645- Bug #1267547: Put proper recursive setup.py call into the

1647
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001648- Bug #1514693: Update turtle's heading when switching between
1649 degrees and radians.
1650
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001651- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001652 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001653
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001654- Bug #1514703: Only setup canvas window in turtle when the canvas
1655 is created.
1656
Martin v. Löwis7596e832006-07-01 15:33:37 +00001657- Bug #1513223: .close() of a _socketobj now releases the underlying
1658 socket again, which then gets closed as it becomes unreferenced.
1659
Fred Drake10497c82006-06-29 02:57:48 +00001660- Bug #1504333: Make sgmllib support angle brackets in quoted
1661 attribute values.
1662
1663- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1664 sgmllib ('[' and ']' were not accepted).
1665
Georg Brandl1be63af2006-06-28 20:23:25 +00001666- Fix a bug in the turtle module's end_fill function.
1667
Brett Cannon53ab5b72006-06-22 16:49:14 +00001668- Bug #1510580: The 'warnings' module improperly required that a Warning
1669 category be either a types.ClassType and a subclass of Warning. The proper
1670 check is just that it is a subclass with Warning as the documentation states.
1671
Georg Brandlad29e632006-06-21 17:45:17 +00001672- The compiler module now correctly compiles the new try-except-finally
1673 statement (bug #1509132).
1674
Neal Norwitz60373cd2006-06-22 06:30:50 +00001675- The wsgiref package is now installed properly on Unix.
1676
Vinay Sajip28e57612006-07-01 10:45:20 +00001677- A bug was fixed in logging.config.fileConfig() which caused a crash on
1678 shutdown when fileConfig() was called multiple times.
1679
Gerhard Häring762fbd32006-07-02 17:48:30 +00001680- The sqlite3 module did cut off data from the SQLite database at the first
1681 null character before sending it to a custom converter. This has been fixed
1682 now.
1683
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001684Extension Modules
1685-----------------
1686
Tim Peters112aad32006-07-19 00:03:19 +00001687- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1688 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1689 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001690
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001691- Assigning None to pointer type fields in ctypes structures possible
1692 overwrote the wrong fields, this is fixed now.
1693
1694- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1695 on non-Windows platforms.
1696
1697- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1698 integer or long, without range checking.
1699
1700- Patch #1517790: It is now possible to use custom objects in the ctypes
1701 foreign function argtypes sequence as long as they provide a from_param
1702 method, no longer is it required that the object is a ctypes type.
1703
1704- The '_ctypes' extension module now works when Python is configured
1705 with the --without-threads option.
1706
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001707- Bug #1513646: os.access on Windows now correctly determines write
1708 access, again.
1709
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001710- Bug #1512695: cPickle.loads could crash if it was interrupted with
1711 a KeyboardInterrupt.

Neal Norwitza12aa882006-07-06 06:45:08 +00001713- Bug #1296433: parsing XML with a non-default encoding and
1714 a CharacterDataHandler could crash the interpreter in pyexpat.
1715
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001716- Patch #1516912: improve Modules support for OpenVMS.

1722
Tim Peters32a83612006-07-10 21:08:24 +00001723- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001724 Previously, the slight difference could cause compilation errors of the
1725 'zlib' module on systems with more than one version of zlib.
1726
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001727- The MSI compileall step was fixed to also support a TARGETDIR
1728 with spaces in it.

1758Core and builtins
1759-----------------
1760
Georg Brandla56b9152006-06-19 06:35:54 +00001761- Patch #1507676: Error messages returned by invalid abstract object operations
1762 (such as iterating over an integer) have been improved and now include the
1763 type of the offending object to help with debugging.
1764
Brett Cannonea3912b2006-06-13 21:46:41 +00001765- Bug #992017: A classic class that defined a __coerce__() method that returned
1766 its arguments swapped would infinitely recurse and segfault the interpreter.
1767
Neal Norwitz909eb122006-06-12 02:13:21 +00001768- Fix the socket tests so they can be run concurrently.
1769
Neal Norwitzb9845e72006-06-12 02:11:18 +00001770- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001771 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001772
Brett Cannon22565aa2006-06-09 22:31:23 +00001773- Bug #532646: object.__call__() will continue looking for the __call__
1774 attribute on objects until one without one is found. This leads to recursion
1775 when you take a class and set its __call__ attribute to an instance of the
1776 class. Originally fixed for classic classes, but this fix is for new-style.
1777 Removes the infinite_rec_3 crasher.
1778
Georg Brandl24250812006-06-09 18:45:48 +00001779- The string and unicode methods startswith() and endswith() now accept
1780 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1781
Brett Cannonde3b0522006-06-08 17:00:45 +00001782- Buffer objects, at the C level, never used the char buffer
1783 implementation even when the char buffer for the wrapped object was
1784 explicitly requested (originally returned the read or write buffer).
1785 Now a TypeError is raised if the char buffer is not present but is
1786 requested.
1787
Georg Brandlddbaa662006-06-04 21:56:52 +00001788- Patch #1346214: Statements like "if 0: suite" are now again optimized
1789 away like they were in Python 2.4.
1790
Georg Brandlb7c8f542006-05-27 12:30:25 +00001791- Builtin exceptions are now full-blown new-style classes instead of
1792 instances pretending to be classes, which speeds up exception handling
1793 by about 80% in comparison to 2.5a2.
1794
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001795- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1796 Unicode 4.1.
1797
Georg Brandlf4ef1162006-05-26 18:03:31 +00001798- Patch #921466: sys.path_importer_cache is now used to cache valid and
1799 invalid file paths for the built-in import machinery which leads to
1800 fewer open calls on startup.
1801
Tim Peters696cf432006-05-24 21:10:40 +00001802- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1803 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1804 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1805 the number of input digits (it was and remains linear-time for bases
1806 2, 4, 8, 16 and 32).
1807
Tim Petersb713ec22006-05-23 18:45:30 +00001808- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1809 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1810 an integer close to ``sys.maxint``. This was repaired by patch
1811 #1335972, which also gives a nice speedup.
1812
Richard Jonescebbefc2006-05-23 18:28:17 +00001813- Patch #1337051: reduced size of frame objects.
1814
1815- PyErr_NewException now accepts a tuple of base classes as its
1816 "base" parameter.
1817
Richard Jones7c88dcc2006-05-23 10:37:38 +00001818- Patch #876206: function call speedup by retaining allocated frame
1819 objects.
1820
Georg Brandl7b90e162006-05-18 07:01:27 +00001821- Bug #1462152: file() now checks more thoroughly for invalid mode
1822 strings and removes a possible "U" before passing the mode to the
1823 C library function.
1824
Neal Norwitz1004a532006-05-15 07:17:23 +00001825- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1826
Neal Norwitz373f0a72006-05-15 07:04:36 +00001827- Bug #1487966: Fix SystemError with conditional expression in assignment
1828
Martin v. Löwis879768d2006-05-11 13:28:43 +00001829- WindowsError now has two error code attributes: errno, which carries
1830 the error values from errno.h, and winerror, which carries the error
1831 values from winerror.h. Previous versions put the winerror.h values
1832 (from GetLastError()) into the errno attribute.
1833
Martin v. Löwis77736712006-05-04 05:51:03 +00001834- Patch #1475845: Raise IndentationError for unexpected indent.
1835
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001836- Patch #1479181: split open() and file() from being aliases for each other.
1837
Tim Peters44bd9862006-06-01 13:49:23 +00001838- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1839 methods were always silently ignored by dictionaries when comparing keys.
1840 They are now passed through (except when using the C API function
1841 ``PyDict_GetItem()``, whose semantics did not change).
1842
1843- Bug #1456209: In some obscure cases it was possible for a class with a
1844 custom ``__eq__()`` method to confuse dict internals when class instances
1845 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1846 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001848Extension Modules
1849-----------------
1850
Trent Mick960a3f82006-06-28 20:30:41 +00001851- Bug #1295808: expat symbols should be namespaced in pyexpat
1852
1853- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1854
Brett Cannon6ee7d012006-06-08 16:23:04 +00001855- Change binascii.hexlify to accept a read-only buffer instead of only a char
1856 buffer and actually follow its documentation.
1857
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001858- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1859
Nick Coghlanc649ec52006-05-29 12:43:05 +00001860- Patch #1478788 (modified version): The functional extension module has
1861 been renamed to _functools and a functools Python wrapper module added.
1862 This provides a home for additional function related utilities that are
1863 not specifically about functional programming. See PEP 309.
1864
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001865- Patch #1493701: performance enhancements for struct module.
1866
Georg Brandl378d5922006-05-17 14:26:50 +00001867- Patch #1490224: time.altzone is now set correctly on Cygwin.
1868
Georg Brandl8d3342b2006-05-16 07:38:27 +00001869- Patch #1435422: zlib's compress and decompress objects now have a
1870 copy() method.
1871
Andrew MacIntyre92913322006-06-13 15:04:24 +00001872- Patch #1454481: thread stack size is now tunable at runtime for thread
1873 enabled builds on Windows and systems with Posix threads support.
1874
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001875- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1876 (up to the system limit of 32K characters).
1877
1878- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1879 As a result, these functions now raise WindowsError instead of OSError.
1880
Tim Peters7a822da2006-05-25 21:50:17 +00001881- ``time.clock()`` on Win64 should use the high-performance Windows
1882 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1883 Windows platforms).
1884
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001885- Calling Tk_Init twice is refused if the first call failed as that
1886 may deadlock.
1887
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001888- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1889 accept it without potentially using an uninitialized pointer.
1890
1891- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1892 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1893 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001894
Gregory P. Smith372b5832006-06-05 18:48:21 +00001895- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001896 [pybsddb project SF patch number 1466734]
1897
Gregory P. Smith372b5832006-06-05 18:48:21 +00001898- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1899 parameter is supplied. [SF pybsddb bug #1477863]
1900
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001901- bsddb: the __len__ method of a DB object has been fixed to return correct
1902 results. It could previously incorrectly return 0 in some cases.
1903 Fixes SF bug 1493322 (pybsddb bug 1184012).
1904
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001905- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1906 aborts the db transaction safely when a modifier callback fails.
1907 Fixes SF python patch/bug #1408584.
1908
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001909- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001910 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001911 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1912 database calls that would previously deadlock. [SF python bug #775414]
1913
Vinay Sajip28e57612006-07-01 10:45:20 +00001914- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001915
Walter Dörwald4994d952006-06-19 08:07:50 +00001916- Patch #1506645: add Python wrappers for the curses functions
1917 is_term_resized, resize_term and resizeterm.

1920-------
1921
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001922- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1923 functions.
1924
Martin v. Löwis3798da02006-06-17 18:44:27 +00001925- Patch #812986: Update turtle output even if not tracing.
1926
Vinay Sajip28e57612006-07-01 10:45:20 +00001927- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001928 Tkinter.BaseWidget.
1929
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001930- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1931
Martin v. Löwis337487e2006-06-17 09:15:14 +00001932- Patch #763580: Add name and value arguments to Tkinter variable
1933 classes.
1934
Georg Brandl83cc0d02006-06-14 08:50:03 +00001935- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1936 mime.types file for determining MIME types.
1937
Georg Brandl2605ca82006-06-14 06:08:31 +00001938- Bug #1339007: Shelf objects now don't raise an exception in their
1939 __del__ method when initialization failed.
1940
Martin v. Löwisd8251432006-06-14 05:21:04 +00001941- Patch #1455898: The MBCS codec now supports the incremental mode for
1942 double-byte encodings.
1943
Tim Peters43898b42006-06-14 04:09:25 +00001944- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1945 guarantee that adjacent triples in the return list always describe
1946 non-adjacent blocks. Previously, a pair of matching blocks could end
1947 up being described by multiple adjacent triples that formed a partition
1948 of the matching pair.
1949
Greg Ward0e0c9f42006-06-11 16:24:11 +00001950- Bug #1498146: fix optparse to handle Unicode strings in option help,
1951 description, and epilog.
1952
Greg Wardd1c797e2006-06-11 14:42:41 +00001953- Bug #1366250: minor optparse documentation error.
1954
Greg Ward7f547402006-06-11 00:40:49 +00001955- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1956 clarify docs.
1957
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001958- The wsgiref package has been added to the standard library.
1959
Nick Coghlan676725d2006-06-08 13:54:49 +00001960- The functions update_wrapper() and wraps() have been added to the functools
1961 module. These make it easier to copy relevant metadata from the original
1962 function when writing wrapper functions.
1963
Tim Petersd6a9eef2006-06-05 01:48:21 +00001964- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1965 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001966
Martin v. Löwis3f767792006-06-04 19:36:28 +00001967- Patch #1359618: Speed up charmap encoder by using a trie structure
1968 for lookup.
1969
Tim Petersd609b1a2006-06-02 23:22:51 +00001970- The functions in the ``pprint`` module now sort dictionaries by key
1971 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1972 if and only if its display required more than one line, although that
1973 wasn't documented. The new behavior increases predictability; e.g.,
1974 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1975
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001976- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1977 (thanks for J. J. Lee).
1978
Georg Brandl2b330372006-05-28 20:23:12 +00001979- Patch #1496206: improve urllib2 handling of passwords with respect to
1980 default HTTP and HTTPS ports.
1981
George Yoshidaf3c65de2006-05-28 16:39:09 +00001982- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1983
Bob Ippolito7298f272006-05-23 18:43:47 +00001984- Patch #1281707: speed up gzip.readline.
1985
Georg Brandlb89316f2006-05-17 15:51:16 +00001986- Patch #1180296: Two new functions were added to the locale module:
1987 format_string() to get the effect of "format % items" but locale-aware,
1988 and currency() to format a monetary number with currency sign.
1989
Georg Brandle3a25832006-05-17 14:56:04 +00001990- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1991 and several features added, such as speed and geometry control.
1992
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001993- Patch #1488881: add support for external file objects in bz2 compressed
1994 tarfiles.
1995
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001996- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1997 stdout arguments, making it possible to redirect input and output
1998 for remote debugging.
1999
2000- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2001 a couple of issues, notably handling of long file names using the
2002 GNU LONGNAME extension.
2003
2004- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2005 new flag when ``name`` is already the name of an option flag.
2006
2007- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2008 package.
2009
2010- Patch #1472854: make the rlcompleter.Completer class usable on non-
2011 UNIX platforms.
2012
2013- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
2014
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00002015- Bug #1472827: correctly escape newlines and tabs in attribute values in
2016 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002046What's New in Python 2.5 alpha 2?
2047=================================
2048
2049*Release date: 27-APR-2006*
2050
2051Core and builtins
2052-----------------
2053
Thomas Heller1b046642006-04-18 18:51:06 +00002054- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2055 by converting these apis from macros into exported functions again:
2056
2057 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2058 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2059 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2060 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2061 PyRun_String Py_CompileString
2062
Martin v. Löwis45294a92006-04-18 06:24:08 +00002063- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2064
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002065- All uses of PyStructSequence_InitType have been changed to initialize
2066 the type objects only once, even if the interpreter is initialized
2067 multiple times.
2068
Neal Norwitz61546162006-04-14 05:20:28 +00002069- Bug #1454485, array.array('u') could crash the interpreter. This was
2070 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2071 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2072
2073- Py_UNICODE is unsigned. It was always documented as unsigned, but
2074 due to a bug had a signed value in previous versions.
2075
Tim Peters3a5e8b12006-04-11 01:44:07 +00002076- Patch #837242: ``id()`` of any Python object always gives a positive
2077 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2078 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002079 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002080 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002081
Tim Peters3a5e8b12006-04-11 01:44:07 +00002082 def __hash__(self):
2083 return id(self) # WRONG
2084
2085 because a hash result must be a (short) Python int but it was always
2086 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002087 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002088 was always usable as a hash value before this patch. That's no longer
2089 necessarily so.
2090
2091- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002092 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002093 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002094 #1454844)
2095
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002096- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2097 involving generators that have paused outside of any ``try`` or ``with``
2098 blocks. (In 2.5a1, a paused generator that was part of a reference
2099 cycle could not be garbage collected, regardless of whether it was
2100 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00002101
Anthony Baxter51bcb682006-04-05 14:51:42 +00002102Extension Modules
2103-----------------
2104
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00002105- Patch #1191065: Fix preprocessor problems on systems where recvfrom
2106 is a macro.
2107
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002108- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2109 fails with an error condition.
2110
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002111- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2112
2113- Bug #1117761: bsddb.*open() no longer raises an exception when using
2114 the cachesize parameter.
2115
2116- Bug #1149413: bsddb.*open() no longer raises an exception when using
2117 a temporary db (file=None) with the 'n' flag to truncate on open.
2118
2119- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2120 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002121
Armin Rigoa9017c32006-04-19 11:50:27 +00002122- Patch #1062014: AF_UNIX sockets under Linux have a special
2123 abstract namespace that is now fully supported.
2124
Anthony Baxter51bcb682006-04-05 14:51:42 +00002125Library
2126-------
2127
Peter Astrand7d1d4362006-07-14 14:04:45 +00002128- Bug #1223937: subprocess.CalledProcessError reports the exit status
2129 of the process using the returncode attribute, instead of
2130 abusing errno.
2131
Tim Peters711bf302006-04-25 03:31:36 +00002132- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2133 a doctest to be skipped (the code is not run, and the expected output
2134 or exception is ignored).
2135
Nick Coghlanda2268f2006-04-24 04:37:15 +00002136- Fixed contextlib.nested to cope with exceptions being raised and
2137 caught inside exit handlers.
2138
Greg Wardab05edc2006-04-23 03:47:58 +00002139- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2140 hex, octal, or binary; add ``append_const`` action; keep going if
2141 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2142 added ``epilog`` for better help generation).
2143
Tim Peters21fbd572006-04-21 21:18:10 +00002144- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2145 called from a thread spawned as a side effect of importing a module.
2146
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002147- The pydoc module now supports documenting packages contained in
2148 .zip or .egg files.
2149
2150- The pkgutil module now has several new utility functions, such
2151 as ``walk_packages()`` to support working with packages that are either
2152 in the filesystem or zip files.
2153
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002154- The mailbox module can now modify and delete messages from
2155 mailboxes, in addition to simply reading them. Thanks to Gregory
2156 K. Johnson for writing the code, and to the 2005 Google Summer of
2157 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002158
Tim Petersc7605f22006-04-17 21:12:33 +00002159- The ``__del__`` method of class ``local`` in module ``_threading_local``
2160 returned before accomplishing any of its intended cleanup.
2161
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002162- Patch #790710: Add breakpoint command lists in pdb.
2163
Martin v. Löwis0db2a982006-04-16 20:55:38 +00002164- Patch #1063914: Add Tkinter.Misc.clipboard_get().
2165
Martin v. Löwis4b501e62006-04-15 08:41:11 +00002166- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
2167
Anthony Baxtere29002c2006-04-12 12:07:31 +00002168- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2169 Windows. Bug #1469163.
2170
Phillip J. Eby47032112006-04-11 01:07:43 +00002171- The warnings, linecache, inspect, traceback, site, and doctest modules
2172 were updated to work correctly with modules imported from zipfiles or
2173 via other PEP 302 __loader__ objects.
2174
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002175- Patch #1467770: Reduce usage of subprocess._active to processes which
2176 the application hasn't waited on.
2177
Martin v. Löwisb04dee92006-04-10 08:34:21 +00002178- Patch #1462222: Fix Tix.Grid.
2179
Neal Norwitza31bf182006-04-09 03:35:43 +00002180- Fix exception when doing glob.glob('anything*/')
2181
Skip Montanaro262fb922006-04-21 02:31:07 +00002182- The pstats.Stats class accepts an optional stream keyword argument to
2183 direct output to an alternate file-like object.
2184
Anthony Baxter51bcb682006-04-05 14:51:42 +00002185Build
2186-----
2187
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002188- The Makefile now has a reindent target, which runs reindent.py on
2189 the library.
2190
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002191- Patch #1470875: Building Python with MS Free Compiler
2192
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002193- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002194
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002195- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2196 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002197 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002198 CXX from --with-cxx-main, see description in README.
2199
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002200- Patch #1429775: Link extension modules with the shared libpython.
2201
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002202- Fixed a libffi build problem on MIPS systems.
2203
Tim Peters8931ff12006-05-13 23:28:20 +00002204- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2205 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2206 and "%zu" for unsigned integers of type ``size_t``.
2207
Anthony Baxter51bcb682006-04-05 14:51:42 +00002208Tests
2209-----
2210
Nick Coghlanda2268f2006-04-24 04:37:15 +00002211- test_contextlib now checks contextlib.nested can cope with exceptions
2212 being raised and caught inside exit handlers.
2213
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002214- test_cmd_line now checks operation of the -m and -c command switches
2215
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002216- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2217 it separately and by hand. It also wasn't cleaning up its changes to
2218 the current Decimal context.
2219
Thomas Woutersabd08882006-04-26 15:53:30 +00002220- regrtest.py now has a -M option to run tests that test the new limits of
2221 containers, on 64-bit architectures. Running these tests is only sensible
2222 on 64-bit machines with more than two gigabytes of memory. The argument
2223 passed is the maximum amount of memory for the tests to use.
2224
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00002225Tools
2226-----
2227
2228- Added the Python benchmark suite pybench to the Tools/ directory;
2229 contributed by Marc-Andre Lemburg.
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002230
Anthony Baxter51bcb682006-04-05 14:51:42 +00002231Documentation
2232-------------
2233
Tim Petersb06d28c2006-05-12 01:57:59 +00002234- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2235
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002236- PEP 343: Added Context Types section to the library reference
2237 and attempted to bring other PEP 343 related documentation into
2238 line with the implementation and/or python-dev discussions.
2239
Tim Peters8dc73d22006-04-24 02:03:16 +00002240- Bug #1337990: clarified that ``doctest`` does not support examples
2241 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +00002242
2243
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002244What's New in Python 2.5 alpha 1?
2245=================================
2246
Anthony Baxterebed3f62006-04-03 15:03:44 +00002247*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002248
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002249Core and builtins
2250-----------------
2251
Nick Coghlan43832302006-04-23 17:04:07 +00002252- PEP 338: -m command line switch now delegates to runpy.run_module
2253 allowing it to support modules in packages and zipfiles
2254
Martin v. Löwisc661b882006-04-20 04:54:23 +00002255- On Windows, .DLL is not an accepted file name extension for
2256 extension modules anymore; extensions are only found if they
2257 end in .PYD.
2258
Martin v. Löwisea62d252006-04-03 10:56:49 +00002259- Bug #1421664: sys.stderr.encoding is now set to the same value as
2260 sys.stdout.encoding.
2261
Neal Norwitz92e212f2006-04-03 04:48:37 +00002262- __import__ accepts keyword arguments.
2263
Georg Brandlccadf842006-03-31 18:54:53 +00002264- Patch #1460496: round() now accepts keyword arguments.
2265
Anthony Baxter262c00a2006-03-30 10:53:17 +00002266- Fixed bug #1459029 - unicode reprs were double-escaped.
2267
Hye-Shik Changd478f342006-03-23 12:32:36 +00002268- Patch #1396919: The system scope threads are reenabled on FreeBSD
2269 5.4 and later versions.
2270
Neal Norwitze98ccf62006-03-23 05:39:47 +00002271- Bug #1115379: Compiling a Unicode string with an encoding declaration
2272 now gives a SyntaxError.
2273
Georg Brandlabd1ff82006-03-18 07:59:59 +00002274- Previously, Python code had no easy way to access the contents of a
2275 cell object. Now, a ``cell_contents`` attribute has been added
2276 (closes patch #1170323).
2277
Tim Peterscf79aac2006-03-16 01:14:46 +00002278- Patch #1123430: Python's small-object allocator now returns an arena to
2279 the system ``free()`` when all memory within an arena becomes unused
2280 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2281 freed. Some applications will see a drop in virtual memory size now,
2282 especially long-running applications that, from time to time, temporarily
2283 use a large number of small objects. Note that when Python returns an
2284 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002285 platform C library will in turn return that memory to the operating system.
2286 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002287 appears to be effective at least on Microsoft C and gcc-based systems.
2288 Thanks to Evan Jones for hard work and patience.
2289
Georg Brandl533ff6f2006-03-08 18:09:27 +00002290- Patch #1434038: property() now uses the getter's docstring if there is
2291 no "doc" argument given. This makes it possible to legitimately use
2292 property() as a decorator to produce a read-only property.
2293
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002294- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2295 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2296 of requiring an int or long in slicing and a few other contexts, enabling
2297 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2298
Neal Norwitz995acdf2006-03-07 05:01:00 +00002299- Fixed various bugs reported by Coverity's Prevent tool.
2300
Brett Cannonbf364092006-03-01 04:25:17 +00002301- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2302 new exception base class, BaseException, which has a new message attribute.
2303 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2304 Raising a string exception now raises a DeprecationWarning.
2305
Thomas Woutersfb609f42006-02-28 16:37:25 +00002306- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2307 explicitly relative, using 'from .module import name' to mean 'from the same
2308 package as this module is in. Imports without dots still default to the
2309 old relative-then-absolute, unless 'from __future__ import
2310 absolute_import' is used.
2311
Brett Cannona7446e32006-02-27 23:39:10 +00002312- Properly check if 'warnings' raises an exception (usually when a filter set
2313 to "error" is triggered) when raising a warning for raising string
2314 exceptions.
2315
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002316- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002317 The name was removed from Include/code.h.
2318
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002319- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002320
Guido van Rossum1968ad32006-02-25 22:38:04 +00002321- Patch 1433928:
2322 - The copy module now "copies" function objects (as atomic objects).
2323 - dict.__getitem__ now looks for a __missing__ hook before raising
2324 KeyError.
2325
Tim Peters84ef21c2006-02-28 20:39:06 +00002326- PEP 343: with statement implemented. Needs ``from __future__ import
2327 with_statement``. Use of 'with' as a variable will generate a warning.
2328 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002329 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002330 The following objects have __context__ methods:
2331 - The built-in file type.
2332 - The thread.LockType type.
2333 - The following types defined by the threading module:
2334 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2335 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002336
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002337- Fix the encodings package codec search function to only search
2338 inside its own package. Fixes problem reported in patch #1433198.
2339
2340 Note: Codec packages should implement and register their own
2341 codec search function. PEP 100 has the details.
2342
Tim Peters9ea89d22006-06-04 03:26:02 +00002343- PEP 353: Using ``Py_ssize_t`` as the index type.
2344
2345- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2346 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2347 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2348 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2349 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002350
Neal Norwitzfc76d632006-01-10 06:03:13 +00002351- Patch #1400181, fix unicode string formatting to not use the locale.
2352 This is how string objects work. u'%f' could use , instead of .
2353 for the decimal point. Now both strings and unicode always use periods.
2354
Neal Norwitz671b9e32006-01-09 07:07:12 +00002355- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2356 configure would break checking curses.h.
2357
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002358- Bug #959576: The pwd module is now builtin. This allows Python to be
2359 built on UNIX platforms without $HOME set.
2360
Neal Norwitzc10978f2005-12-19 06:07:16 +00002361- Bug #1072182, fix some potential problems if characters are signed.
2362
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002363- Bug #889500, fix line number on SyntaxWarning for global declarations.
2364
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002365- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2366
Neal Norwitze7214a12005-12-18 05:03:17 +00002367- Support for converting hex strings to floats no longer works.
2368 This was not portable. float('0x3') now raises a ValueError.
2369
Barry Warsaw2a38a862005-12-18 01:27:35 +00002370- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002371 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002372 is now displayed in interactive prompt banner.
2373
Georg Brandlfa166682005-12-17 21:45:17 +00002374- Implementation of PEP 341 - Unification of try/except and try/finally.
2375 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002376 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002377
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002378- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2379 now encodes backslash correctly.
2380
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002381- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2382
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002383- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002384 and long longs.
2385
Neal Norwitz67715f02005-11-09 06:59:35 +00002386- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002387 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002388 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002389
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002390- Replaced most Unicode charmap codecs with new ones using the
2391 new Unicode translate string feature in the builtin charmap
2392 codec; the codecs were created from the mapping tables available
2393 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2394 encodings now include a mapping for the Apple logo)
2395
Tim Peterse3547fd2005-12-16 23:13:57 +00002396- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002397
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002398- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002399
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002400- A new AST parser implementation was completed. The abstract
2401 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002402 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002403
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002404- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002405 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2406
Neal Norwitz708e51a2005-10-03 04:48:15 +00002407- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2408
Neal Norwitz11bd1192005-10-03 00:54:56 +00002409- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2410 Provide a warning when a directory is passed on the command line.
2411
Neal Norwitz40d37812005-10-02 01:48:49 +00002412- Fix segfault with invalid coding.
2413
2414- SF bug #772896: unknown encoding results in MemoryError.
2415
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002416- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002417 supported a __len__() method which evaluated to False when the iterator
2418 was empty.
2419
Guido van Rossum630db602005-09-20 18:49:54 +00002420- On 64-bit platforms, when __len__() returns a value that cannot be
2421 represented as a C int, raise OverflowError.
2422
Skip Montanarof8948ca2005-09-19 03:54:46 +00002423- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002424 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002425
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002426- SF bug #893549: parsing keyword arguments was broken with a few format
2427 codes.
2428
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002429- Changes donated by Elemental Security to make it work on AIX 5.3
2430 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2431 bug #105470: test_pwd fails on 64bit system (Opteron).
2432
Guido van Rossum539c6622005-09-14 17:49:54 +00002433- Changes donated by Elemental Security to make it work on HP-UX 11 on
2434 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2435
Georg Brandl4550b8d2005-08-26 06:43:52 +00002436- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002437 (fixes bug #1119418).
2438
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002439- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2440
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002441- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2442 exceptions that cause a function to exit.
2443
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002444- The implementation of set() and frozenset() was revised to use its
2445 own internal data structure. Memory consumption is reduced by 1/3
2446 and there are modest speed-ups as well. The API is unchanged.
2447
Tim Petersde7990b2005-07-17 23:45:23 +00002448- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2449
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002450- SF bug #1229429: PyObject_CallMethod failed to decrement some
2451 reference counts in some error exit cases.
2452
Tim Petersecc6e6a2005-07-10 22:30:55 +00002453- SF bug #1185883: Python's small-object memory allocator took over
2454 a block managed by the platform C library whenever a realloc specified
2455 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002456 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002457 portable way to copy data from the C-managed block into Python's
2458 small-object space without risking a memory fault. Python's small-object
2459 realloc now leaves such blocks under the control of the platform C
2460 realloc.
2461
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002462- SF bug #1232517: An overflow error was not detected properly when
2463 attempting to convert a large float to an int in os.utime().
2464
Raymond Hettinger3296e692005-06-29 23:29:56 +00002465- SF bug #1224347: hex longs now print with lowercase letters just
2466 like their int counterparts.
2467
Michael W. Hudson188d4362005-06-20 16:52:57 +00002468- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2469 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2470 interpreter states; back out that fix and do a better job (see
2471 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2472 for a longer write-up of the problem).
2473
Michael W. Hudsondf888462005-06-03 14:41:55 +00002474- SF patch #1180995: marshal now uses a binary format by default when
2475 serializing floats.
2476
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002477- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2478 the routines that promise to produce IEEE 754 binary representations
2479 of floats now simply copy bytes around.
2480
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002481- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2482 278.
2483
Brett Cannonc3647ac2005-04-26 03:45:26 +00002484- patch #1109424: int, long, float, complex, and unicode now check for the
2485 proper magic slot for type conversions when subclassed. Previously the
2486 magic slot was ignored during conversion. Semantics now match the way
2487 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002488 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002489 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002490 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002491
Barry Warsawc8d907c2005-04-19 23:43:40 +00002492- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2493 NULL, now raise an AttributeError when attempting to set or delete the
2494 attribute. Previously a TypeError was raised, but this was inconsistent
2495 with the equivalent pure-Python implementation.
2496
Michael W. Hudson774479c2005-04-18 08:46:17 +00002497- It is now safe to call PyGILState_Release() before
2498 PyEval_InitThreads() (note that if there is reason to believe there
2499 are multiple threads around you still must call PyEval_InitThreads()
2500 before using the Python API; this fix is for extension modules that
2501 have no way of knowing if Python is multi-threaded yet).
2502
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002503- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2504 disabled caused a crash.
2505
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002506- Bug #1165306: instancemethod_new allowed the creation of a method
2507 with im_class == im_self == NULL, which caused a crash when called.
2508
Tim Petersecc6e6a2005-07-10 22:30:55 +00002509- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002510 fixes the crash seen in bug #1165761
2511
Raymond Hettinger96229b12005-03-11 06:49:40 +00002512- Added two new builtins, any() and all().
2513
Brett Cannon409d8f22005-03-05 06:47:57 +00002514- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002515 (e.g., ``class C(): pass`` is no longer a syntax error).
2516 Patch #1176012 added support to the 'parser' module and 'compiler' package
2517 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002518
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002519- Patch #1115086: Support PY_LONGLONG in structmember.
2520
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002521- Bug #1155938: new style classes did not check that __init__() was
2522 returning None.
2523
Tim Petersecc6e6a2005-07-10 22:30:55 +00002524- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002525 ('\') with a specific error message.
2526
Martin v. Löwisff232d72005-03-03 09:24:38 +00002527- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2528
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002529- Bug #1124295: the __name__ attribute of file objects was
2530 inadvertently made inaccessible in restricted mode.
2531
Tim Petersecc6e6a2005-07-10 22:30:55 +00002532- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002533 an ferror() call.
2534
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002535- min() and max() now support key= arguments with the same meaning as in
2536 list.sort().
2537
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002538- The peephole optimizer now performs simple constant folding in expressions:
2539 (2+3) --> (5).
2540
Raymond Hettingera422c342005-01-11 03:03:27 +00002541- set and frozenset objects can now be marshalled. SF #1098985.
2542
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002543- Bug #1077106: Poor argument checking could cause memory corruption
2544 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002545
Jeremy Hyltonab630502005-02-04 18:44:06 +00002546- The parser did not complain about future statements in illegal
2547 positions. It once again reports a syntax error if a future
2548 statement occurs after anything other than a doc string.
2549
Neil Schemenauercf52c072005-08-12 17:34:58 +00002550- Change the %s format specifier for str objects so that it returns a
2551 unicode instance if the argument is not an instance of basestring and
2552 calling __str__ on the argument returns a unicode instance.
2553
Tim Petersf4e69282006-02-27 17:15:31 +00002554- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2555 current thread state when the auto-GIL-state machinery knows about
2556 it (since the thread state is being deleted, continuing to remember it
2557 can't help, but can hurt if another thread happens to get created with
2558 the same thread id).
2559
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002560Extension Modules
2561-----------------
2562
Georg Brandl43f08a82006-03-31 18:01:16 +00002563- Patch #1380952: fix SSL objects timing out on consecutive read()s
2564
Neal Norwitz05a45592006-03-20 06:30:08 +00002565- Patch #1309579: wait3 and wait4 were added to the posix module.
2566
Anthony Baxterfa869072006-03-20 05:21:58 +00002567- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2568 In addition, the existing ulaw code was updated.
2569
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002570- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002571 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002572
Neal Norwitz10be10c2006-03-16 06:50:13 +00002573- Everything under lib-old was removed. This includes the following modules:
2574 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002575 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002576 util, whatsound, whrandom, zmod
2577
2578- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2579
2580- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002581 is deprecated. The undocumented re.engine variable no longer exists.
2582
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002583- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2584 SS2 (single-shift 2) escape sequences correctly.
2585
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002586- The unicodedata module was updated to the 4.1 version of the Unicode
2587 database. The 3.2 version is still available as unicodedata.db_3_2_0
2588 for applications that require this specific version (such as IDNA).
2589
Neal Norwitzb62c4332006-03-04 18:35:47 +00002590- The timing module is no longer built by default. It was deprecated
2591 in PEP 4 in Python 2.0 or earlier.
2592
Guido van Rossum1968ad32006-02-25 22:38:04 +00002593- Patch 1433928: Added a new type, defaultdict, to the collections module.
2594 This uses the new __missing__ hook behavior added to dict (see above).
2595
Georg Brandldbd83392006-02-20 09:42:33 +00002596- Bug #854823: socketmodule now builds on Sun platforms even when
2597 INET_ADDRSTRLEN is not defined.
2598
Georg Brandlf4f44152006-02-18 22:29:33 +00002599- Patch #1393157: os.startfile() now has an optional argument to specify

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002750- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2751 been renamed to have only a single underscore prefix. This was done to
2752 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002753
Nick Coghlan43832302006-04-23 17:04:07 +00002754- PEP 338: new module runpy defines a run_module function to support
2755 executing modules which provide access to source code or a code object
2756 via the PEP 302 import mechanisms.
2757
Anthony Baxter93f5b932006-04-03 08:05:07 +00002758- The email module's parsedate_tz function now sets the daylight savings

2766 in attribute values.
2767
Anthony Baxterc51ee692006-04-01 00:57:31 +00002768- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002769 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002770 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002771 module will not be built.
2772
Tim Petersc17976e2006-04-01 00:26:53 +00002773- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2774 aren't officially supported here, and trying to use them will probably
2775 raise an exception some day. But dicts have been allowed, and "mostly
2776 worked", so support for them won't go away without warning.
2777
Georg Brandl338ef7d2006-03-31 18:42:16 +00002778- Bug #1445068: getpass.getpass() can now be given an explicit stream

2796
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002797- email 4.0 package now integrated. This is largely the same as the email 3.0
2798 package that was included in Python 2.3, except that PEP 8 module names are
2799 now used (e.g. mail.message instead of email.Message). The MIME classes
2800 have been moved to a subpackage (e.g. email.mime.text instead of
2801 email.MIMEText). The old names are still supported for now. Several
2802 deprecated Message methods have been removed and lots of bugs have been
2803 fixed. More details can be found in the email package documentation.
2804
Walter Dörwald40108c92006-03-27 08:15:44 +00002805- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2806 (a subclass of tuple) that provides incremental decoders and encoders
2807 (a way to use stateful codecs without the stream API). Python functions
2808 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2809 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2810 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002812- Patch #1359365: Calling next() on a closed StringIO.String object raises
2813 a ValueError instead of a StopIteration now (like file and cString.String do).
2814 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2815 called before (like file and StringIO.StringIO do).

2883
Neal Norwitz338e7862005-12-23 21:27:46 +00002884- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2885 LoadError as documented, instead of IOError. For compatibility,
2886 LoadError subclasses IOError.
2887
Brett Cannon3cbd0382005-12-16 22:49:23 +00002888- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002889 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2890 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2891 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2892 Ronald L. Rivest offered this advice for Python:
2893
2894 "The consensus of researchers in this area (at least as
2895 expressed at the NIST Hash Function Workshop 10/31/05),
2896 is that SHA-256 is a good choice for the time being, but
2897 that research should continue, and other alternatives may
2898 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002899
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002900- Added a subset of Fredrik Lundh's ElementTree package. Available

2953 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002954 correct line numbers for decoding errors in source code.

2993 Bug #1224621.
2994
Raymond Hettinger68c04532005-06-10 11:05:19 +00002995- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002996 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002997 the generate_tokens() function now accepts a callable argument that
2998 terminates by raising StopIteration.
2999
Georg Brandl9166e1a2005-06-04 09:20:03 +00003000- Bug #1196315: fix weakref.WeakValueDictionary constructor.

3014 them to PyPI.
3015
Raymond Hettinger267b8682005-03-27 10:47:39 +00003016- decimal operator and comparison methods now return NotImplemented
3017 instead of raising a TypeError when interacting with other types. This
3018 allows other classes to implement __radd__ style methods and have them
3019 work as expected.
3020
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003021- Bug #1163325: Decimal infinities failed to hash. Attempting to
3022 hash a NaN raised an InvalidOperation instead of a TypeError.
3023
Tim Petersecc6e6a2005-07-10 22:30:55 +00003024- Patch #918101: Add tarfile open mode r|* for auto-detection of the

3058
Guido van Rossumd0641422005-02-03 15:01:24 +00003059- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3060 disables recursive traversal through instance attributes, which can
3061 be exploited in various ways.
3062
Tim Peterse3547fd2005-12-16 23:13:57 +00003063- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003064 flags on the HTTP listening socket.
3065
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003066- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3067 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3068
Fred Drakefbdeaad2006-07-29 16:56:15 +00003069- Patches #893642, #1039083: add allow_none, encoding arguments to
3070 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003071

3075
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003076- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3077
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003078- Enhancements to the csv module:
3079
3080 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003081 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003082 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003083 + Dialect parameter parsing has been re-implemented to improve error
3084 reporting.
3085 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3086 dictates.
3087 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003088 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003089 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003090 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3091 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003092 + reader now allows \r characters to be quoted (previously it only allowed
3093 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003094 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003095 + Dialect classes passed to the module are no longer instantiated by
3096 the module before being parsed (the former validation scheme required
3097 this, but the mechanism was unreliable).
3098 + The dialect registry now contains instances of the internal
3099 C-coded dialect type, rather than references to python objects.
3100 + the internal c-coded dialect type is now immutable.
3101 + register_dialect now accepts the same keyword dialect specifications
3102 as the reader and writer, allowing the user to register dialects
3103 without first creating a dialect class.
3104 + a configurable limit to the size of parsed fields has been added -
3105 previously, an unmatched quote character could result in the entire
3106 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003107 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003108 the parser field size limit (returning the former limit). The initial
3109 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003110 + A line_num attribute has been added to the reader object, which tracks
3111 the number of lines read from the source iterator. This is not
3112 the same as the number of records returned, as records can span
3113 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003114 + reader and writer objects were not being registered with the cyclic-GC.
3115 This has been fixed.
3116
Brett Cannone6539c42005-01-08 02:43:53 +00003117- _DummyThread objects in the threading module now delete self.__block that is
3118 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3119 lock primitives tend to be limited in number and thus should not be wasted on
3120 a _DummyThread object. Fixes bug #1089632.
3121
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003122- The imghdr module now detects Exif files.
3123
Raymond Hettinger6065d322004-12-20 23:51:53 +00003124- StringIO.truncate() now correctly adjusts the size attribute.
3125 (Bug #951915).
3126
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003127- locale.py now uses an updated locale alias table (built using
3128 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3129 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003130 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003131
Raymond Hettinger3557f422004-12-07 12:02:02 +00003132- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3133
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003134- the pickle module no longer accepts the deprecated None option in the
3135 args tuple returned by __reduce__().
3136
Brett Cannon84667c02004-12-07 03:25:18 +00003137- optparse now optionally imports gettext. This allows its use in setup.py.
3138
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003139- the pickle module no longer uses the deprecated bin parameter.
3140
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003141- the shelve module no longer uses the deprecated binary parameter.
3142

3144
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003145- the filecmp module no longer uses the deprecated use_statcache argument.
3146
Raymond Hettinger664347b2004-12-04 21:21:53 +00003147- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3148 extended or overridden by subclasses. Formerly, the subclassed method would
3149 be ignored by the rest of the module. (Bug #1078905).
3150
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003151- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003152 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003153
Walter Dörwald36733692004-12-22 12:50:50 +00003154- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3155 once when a size argument is given. This prevents a buffer overflow in the
3156 tokenizer with very long source lines.
3157
Barry Warsaw538561e2006-01-01 21:48:54 +00003158- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3159 immediately after creating the object, without any intervening
3160 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003161
Skip Montanaro05885812005-01-16 20:48:27 +00003162- The reconvert.quote function can now emit triple-quoted strings. The
3163 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003164
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003165- ``UserString.MutableString`` now supports negative indices in
3166 ``__setitem__`` and ``__delitem__``
3167
Greg Ward40407942005-03-05 02:53:17 +00003168- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3169 correctly.
3170
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003171- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3172 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3173 character even if the user has passed a size parameter to get a proper
3174 line ending. Remove the special handling of a "\r\n" that has been split
3175 between two lines.
3176
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003177- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3178 about illegal code points. The codec now supports PEP 293 style error
3179 handlers.
3180
Walter Dörwald78a78b02005-09-01 12:04:29 +00003181- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003182 from the input stream, so that the output is a byte string in the correct
3183 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003184
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003185- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3186 considering it exactly like a '*'.
3187
Walter Dörwald007f8df2005-10-09 19:42:27 +00003188- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3189 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003190
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003191- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3192
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003193- Patch #1413711: Certain patterns of differences were making difflib
3194 touch the recursion limit.
3195
Walter Dörwald58917a62006-03-31 15:26:22 +00003196- Bug #947906: An object oriented interface has been added to the calendar
3197 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003198 called as a script (e.g. via ``python -mcalendar``). Localized month and
3199 weekday names can be ouput (even if an exotic encoding is used) using
3200 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003202Build
3203-----
3204
Neal Norwitz602d3392006-03-31 08:21:40 +00003205- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3206 by using -mieee gcc option.
3207

3209
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003210- Build support for Win64-AMD64 was added.
3211
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003212- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3213
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003214- Patch #881820: look for openpty and forkpty also in libbsd.
3215
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003216- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3217 The zlib module is now builtin on Windows.
3218
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003219- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3220
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003221- Bug #1189330: configure did not correctly determine the necessary
3222 value of LINKCC if python was built with GCC 4.0.
3223
Trent Mick8321b422005-07-26 02:29:21 +00003224- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3225 vulnerability in zlib 1.2.1 and 1.2.2.
3226
Brett Cannon08cd5982005-04-24 22:26:38 +00003227- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3228 flags that change binary compatibility. Changes were also made to
3229 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003230 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003231
Bob Ippolitoed233462005-03-29 13:47:59 +00003232- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3233 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3234 no longer exists). This configure patch makes things right.
3235
Martin v. Löwise2713be2005-03-08 15:03:08 +00003236- Bug #1158607: Build with --disable-unicode again.
3237
Brett Cannon46d96232005-02-16 00:07:19 +00003238- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3239 defined. Discovered as a result of not being able to build on OS X.
3240
Brett Cannon516592f2004-12-07 00:42:59 +00003241- setup.py now uses the directories specified in LDFLAGS using the -L option
3242 and in CPPFLAGS using the -I option for adding library and include
3243 directories, respectively, for compiling extension modules against. This has
3244 led to the core being compiled using the values in CPPFLAGS. It also removes
3245 the need for the special-casing of both DarwinPorts and Fink for darwin since
3246 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3247 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3248 Fink, ``-I/opt/local/include`` for DarwinPorts).
3249
Brett Cannon43802422005-02-10 20:48:03 +00003250- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3251 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3252 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3253 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003255C API
3256-----
3257
Tim Petersc9d78aa2006-03-26 23:27:58 +00003258- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3259 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3260 is obtained via the ``PyObject_`` family, it must be released via the
3261 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3262 always been officially true, but when Python's small-object allocator was
3263 introduced, an attempt was made to cater to a few extension modules
3264 discovered at the time that obtained memory via ``PyObject_New`` but
3265 released it via ``PyMem_DEL``. It's years later, and if such code still
3266 exists it will fail now (probably with segfaults, but calling wrong
3267 low-level memory management functions can yield many symptoms).
3268
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003269- Added a C API for set and frozenset objects.
3270
Raymond Hettinger66517482004-12-03 11:45:13 +00003271- Removed PyRange_New().
3272
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003273- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3274 mapping argument now. This string is used as a mapping table. Byte values
3275 greater than the length of the string and 0xFFFE are treated as undefined
3276 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003283
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003284- Patch #1276356: New resource "urlfetch" is implemented. This enables
3285 even impatient people to run tests that require remote files.
