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

101 its symbolic link.
102
Thomas Heller275e2292008-08-19 17:17:37 +0000103- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
104 api functions without holding the GIL, which could lead to a fatal
105 error when they failed.
106
Amaury Forgeot d'Arc22679b82008-08-18 19:33:42 +0000107- Issue #2234: distutils failed for some versions of the cygwin compiler. The
108 version reported by these tools does not necessarily follow the python
109 version numbering scheme, so the module is less strict when parsing it.
110
Hirokazu Yamamoto1d63a452008-08-17 09:49:10 +0000111- Issue #2222: Fixed reference leak when occured os.rename()
112 fails unicode conversion on 2nd parameter. (windows only)
113

130 handlers that derive the same default base class.
131
Amaury Forgeot d'Arc198e3532008-03-27 23:41:59 +0000132- Issue #2495: tokenize.untokenize now inserts a space between two consecutive
133 string literals; previously, ["" ""] was rendered as [""""], which is
134 incorrect python code.
135
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +0000136- Issue #2482: Make sure that the coefficient of a Decimal is always
137 stored as a str instance, not as a unicode instance. This ensures
138 that str(Decimal) is always an instance of str. This fixes a
139 regression from Python 2.5.1 to Python 2.5.2.
140
Mark Dickinson26c25d92008-03-25 14:35:25 +0000141- Issue #2478: fix failure of decimal.Decimal(0).sqrt()

152 root directory, and also exclude .hg, .git, .bzr, and _darcs.
153
Andrew M. Kuchling37d4f7b2008-02-23 19:06:54 +0000154- Bug #1389051: imaplib causes excessive memory fragmentation when reading

168 in the common case when the data is returned from the underlying socket
169 in increments much smaller than bignumber.
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +0000170
Gregory P. Smithb4bc9b92008-08-04 00:15:54 +0000171- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
172 argument in python 2.5, this broke code that subclassed Popen to include its

252-----------------
253
Martin v. Löwis73c01d42008-02-14 11:26:18 +0000254- Added checks for integer overflows, contributed by Google. Some are

257
Amaury Forgeot d'Arc3e5f8a62008-02-08 01:05:21 +0000258- Issue #2045: Fix an infinite recursion triggered when printing a subclass of
259 collections.defaultdict, if its default_factory is set to a bound method.
260
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000261- Issue #1920: "while 0" statements were completely removed by the compiler,
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000262 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000263 the condition is false. Now the compiler correctly emits bytecode for the
264 "else" suite.
265
Guido van Rossumd933e0a2008-01-24 18:28:37 +0000266- A few crashers fixed: weakref_in_del.py (issue #1377858);

292 format code incorrectly truncated the length to an int, even when
293 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
294 results with huge strings.
295
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000296- Issue #1445: Fix a SystemError when accessing the ``cell_contents``

Neal Norwitzff4b63b2006-08-04 04:50:21 +00001220
1221Core and builtins
1222-----------------
1223
Neal Norwitz24b6f202006-09-05 04:43:56 +00001224- Fix infinite recursion when subclassing long and overriding __hash__.
1225
1226- Fix concatenation (+=) of long strings.
1227
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001228- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001229 compared equal or unequal to a string and a UnicodeDecodeError
1230 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001231
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001232 Instead, the equal (==) and unequal (!=) comparison operators will
1233 now issue a UnicodeWarning and interpret the two objects as
1234 unequal. The UnicodeWarning can be filtered as desired using
1235 the warning framework, e.g. silenced completely, turned into an
1236 exception, logged, etc.
1237
1238 Note that compare operators other than equal and unequal will still
1239 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001240
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001241- Fix segfault when doing string formatting on subclasses of long.
1242
1243- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1244 with new-style classes.
1245
1246- Fix bug related to __len__ functions returning negative values with
1247 classic classes.
1248
1249- Patch #1538606, Fix __index__() clipping. There were some problems
1250 discovered with the API and how integers that didn't fit into Py_ssize_t
1251 were handled. This patch attempts to provide enough alternatives
1252 to effectively use __index__.
1253
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001254- Bug #1536021: __hash__ may now return long int; the final hash
1255 value is obtained by invoking hash on the long int.
1256
Thomas Hellerab1049c2006-08-08 17:37:00 +00001257- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1258
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001259- Bug #1535165: fixed a segfault in input() and raw_input() when
1260 sys.stdin is closed.
1261
Thomas Heller74d36f02006-08-04 18:17:40 +00001262- On Windows, the PyErr_Warn function is now exported from
1263 the Python dll again.
1264
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001265- Bug #1191458: tracing over for loops now produces a line event
1266 on each iteration. Fixing this problem required changing the .pyc
1267 magic number. This means that .pyc files generated before 2.5c1
1268 will be regenerated.
1269
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001270- Bug #1333982: string/number constants were inappropriately stored
1271 in the byte code and co_consts even if they were not used, ie
1272 immediately popped off the stack.
1273
Georg Brandle9462c72006-08-04 18:03:37 +00001274- Fixed a reference-counting problem in property().

1277Library
1278-------
1279
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001280- Fix a bug in the ``compiler`` package that caused invalid code to be
1281 generated for generator expressions.
1282
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001283- The distutils version has been changed to 2.5.0. The change to
1284 keep it programmatically in sync with the Python version running
1285 the code (introduced in 2.5b3) has been reverted. It will continue
1286 to be maintained manually as static string literal.
1287
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001288- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001289 and this cannot be converted to the required C type, an exception is
1290 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001291 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001292
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001293- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001294 an exception.
1295
Tim Peterscbdd3502006-09-05 01:47:53 +00001296- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001297 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001298 workarounds for clocks with low resolution, to stop the code yielding
1299 duplicate UUIDs.
1300
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001301- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1302 before raising SystemExit, allowing IDLE to honor quit() and exit().
1303
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001304- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1305
Georg Brandl7a1af772006-08-14 21:55:28 +00001306- Patch #1536071: trace.py should now find the full module name of a
1307 file correctly even on Windows.
1308
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001309- logging's atexit hook now runs even if the rest of the module has
1310 already been cleaned up.
1311
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001312- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001313
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001314- Bug #1531405, format_exception no longer raises an exception if
1315 str(exception) raised an exception.
1316
Neil Schemenauer06ded092006-08-04 16:20:30 +00001317- Fix a bug in the ``compiler`` package that caused invalid code to be
1318 generated for nested functions.

1329 raises the correct exceptions.
1330
Thomas Heller1ce433e2006-08-14 16:20:04 +00001331- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1332 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1333
Thomas Heller86720042006-08-14 11:17:48 +00001334- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1335 uses the _as_parameter_ attribute when objects are passed to foreign
1336 function calls. The ctypes version number was changed to 1.0.1.
1337
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001338- Bug #1530559, struct.pack raises TypeError where it used to convert.
1339 Passing float arguments to struct.pack when integers are expected
1340 now triggers a DeprecationWarning.

Neal Norwitza1f10902006-07-12 07:28:29 +00001389
1390Core and builtins
1391-----------------
1392
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001393- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001394 returned a long (see PEP 353).
1395
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001396- Bug #1515471: string.replace() accepts character buffers again.
1397
Neal Norwitz07aadb12006-07-30 06:55:48 +00001398- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1399 This provides the proper warning for struct.pack().
1400 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1401
Neal Norwitz0d62a062006-07-30 06:53:31 +00001402- Patch #1531113: Fix augmented assignment with yield expressions.
1403 Also fix a SystemError when trying to assign to yield expressions.
1404
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001405- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1406 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1407 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1408 excessive filesystem operations during imports.
1409
Tim Petersbc24eee2006-07-27 01:14:53 +00001410- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1411 operations on signed longs that are formally undefined by C.
1412 Unfortunately, at least one compiler now cares about that, so complicated
1413 the code to make that compiler happy again.
1414
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001415- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1416
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001417- Patch #1232023: Stop including current directory in search
1418 path on Windows.
1419
Neal Norwitze1fdb322006-07-21 05:32:28 +00001420- Fix some potential crashes found with failmalloc.
1421
Neal Norwitze7563102006-07-17 01:00:16 +00001422- Fix warnings reported by Klocwork's static analysis tool.
1423
Neal Norwitz84be93b2006-07-16 01:50:38 +00001424- Bug #1512814, Fix incorrect lineno's when code within a function
1425 had more than 255 blank lines.
1426
Georg Brandl9dceedb2006-07-12 15:31:17 +00001427- Patch #1521179: Python now accepts the standard options ``--help`` and
1428 ``--version`` as well as ``/?`` on Windows.
1429
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001430- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001431 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001432 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001433
Tim Peters112aad32006-07-19 00:03:19 +00001434- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001435 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001436 new ``sys._current_frames()`` returns a dictionary with one entry,
1437 mapping the faux "thread id" 0 to the current frame.
1438
Ronald Oussoren3075e162006-07-25 20:28:55 +00001439- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

Martin v. Löwis961b91b2006-08-02 13:53:55 +00001445- Correction of patch #1455898: In the mbcs decoder, set final=False
1446 for stream decoder, but final=True for the decode function.
1447
Georg Brandl07fec3a2006-08-01 18:49:24 +00001448- os.urandom no longer masks unrelated exceptions like SystemExit or
1449 KeyboardInterrupt.

Tim Peters4643c2f2006-08-10 22:45:34 +00001451- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001452 shutil.copytree on Windows
1453
Georg Brandle34ac7c2006-07-30 11:07:23 +00001454- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1455 refers to file descriptors, not file objects.
1456
Tim Peterscbdd3502006-09-05 01:47:53 +00001457- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001458 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001459 #1513611, and probably others.
1460
Georg Brandledd9b0d2006-07-29 09:33:26 +00001461- Bug #1441397: The compiler module now recognizes module and function
1462 docstrings correctly as it did in Python 2.4.
1463
Tim Peters6f681472006-07-27 23:44:37 +00001464- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1465 lost that tests are sorted by name before being run. This rarely
1466 matters for well-written tests, but can create baffling symptoms if
1467 side effects from one test to the next affect outcomes. ``DocTestFinder``
1468 has been changed to sort the list of tests it returns.
1469
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001470- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001471 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001472
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001473- Bug #978833: Really close underlying socket in _socketobject.close.
1474
Georg Brandldb232dc2006-08-20 13:15:43 +00001475- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1476 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001477
Georg Brandlcf0c1722006-07-26 07:23:32 +00001478- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1479 to recursive calls and call it with the failing package name.
1480
Martin v. Löwis0b483032006-07-25 09:53:12 +00001481- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1482
Georg Brandlc13c34c2006-07-24 14:09:56 +00001483- Patch #1515343: Fix printing of deprecated string exceptions with a
1484 value in the traceback module.
1485
Greg Ward48fae7a2006-07-23 16:05:51 +00001486- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1487
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001488- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1489
Brett Cannoncaebe222006-07-18 04:41:36 +00001490- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1491 argument tuple. For arguments where zero is illegal, the value is forced to
1492 the minimum value that is correct. This is to support an undocumented but
1493 common way people used to fill in inconsequential information in the time
1494 tuple pre-2.4.
1495
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001496- Patch #1220874: Update the binhex module for Mach-O.
1497
Barry Warsawb110bad2006-07-21 14:51:07 +00001498- The email package has improved RFC 2231 support, specifically for
1499 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1500 (name*0=<blah>) parameter continuations. This may change the types of
1501 values returned from email.message.Message.get_param() and friends.
1502 Specifically in some cases where non-encoded continuations were used,
1503 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1504 will just return the string (since non-encoded continuations don't have
1505 charset and language parts).
1506
1507 Also, whereas % values were decoded in all parameter continuations, they are
1508 now only decoded in encoded parameter parts.
1509
Ronald Oussoren3075e162006-07-25 20:28:55 +00001510- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1511
1512- Bug #1517996: IDLE now longer shows the default Tk menu when a
1513 path browser, class browser or debugger is the frontmost window on MacOS X
1514
Barry Warsaw00decd72006-07-27 23:43:15 +00001515- Patch #1520294: Support for getset and member descriptors in types.py,
1516 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1517 of an object against these built-in types and more importantly, for getting
1518 their docstrings printed in the interactive interpreter's help() function.

1522-----------------
1523
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001524- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1525 a socket operation on a socket with a timeout, the exception will be
1526 caught correctly. Previously, the exception was not caught.
1527
Thomas Heller1393d6a2006-07-28 21:43:20 +00001528- Patch #1529514: The _ctypes extension is now compiled on more
1529 openbsd target platforms.
1530
Tim Peters9cab5932006-07-28 00:30:00 +00001531- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1532 a memory leak, affecting pickles and deep copies.
1533
Tim Petersbc24eee2006-07-27 01:14:53 +00001534- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001535 Paul Eggert.
1536
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001537- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1538
Thomas Hellerce049a02006-07-14 17:51:14 +00001539- Patch #1521817: Index range checking on ctypes arrays containing
1540 exactly one element enabled again. This allows iterating over these
1541 arrays, without the need to check the array size before.
1542
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001543- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001544 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001545 /dev/null in certain cases; this is now fixed.
1546
Thomas Heller47d7a062006-07-12 08:43:47 +00001547- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1548 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001549
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001550- Because of a misspelled preprocessor symbol, ctypes was always
1551 compiled without thread support; this is now fixed.
1552
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001553- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1554 methods now allow their database parameter to be None as the
1555 sleepycat API allows.
1556
Matt Flemingec926502006-07-28 11:27:27 +00001557- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1558 bluetooth API compared with Linux and FreeBSD.
1559
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001560Tests
1561-----
1562
1563- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1564 how long the test file should take to play. Now accepts taking 2.93 secs
1565 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1566
Georg Brandl4793aa32006-07-28 18:31:39 +00001567- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1568 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1569 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001576Mac
1577---
1578
1579- PythonLauncher now works correctly when the path to the script contains
1580 characters that are treated specially by the shell (such as quotes).
1581
1582- Bug #1527397: PythonLauncher now launches scripts with the working directory
1583 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001584 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001585 expect.

1594-----------------
1595
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001596- Bug #1441486: The literal representation of -(sys.maxint - 1)
1597 again evaluates to a int object, not a long.
1598
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001599- Bug #1501934: The scope of global variables that are locally assigned
1600 using augmented assignment is now correctly determined.
1601
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001602- Bug #927248: Recursive method-wrapper objects can now safely
1603 be released.
1604
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001605- Bug #1417699: Reject locale-specific decimal point in float()
1606 and atof().
1607
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001608- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1609 omit a default "error" argument for NULL pointer. This allows
1610 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001611
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001612- Bug #1519018: 'as' is now validated properly in import statements.
1613
Neal Norwitz28746ab2006-07-09 22:14:42 +00001614- On 64 bit systems, int literals that use less than 64 bits are
1615 now ints rather than longs.
1616
Neal Norwitzed657552006-07-10 00:04:44 +00001617- Bug #1512814, Fix incorrect lineno's when code at module scope
1618 started after line 256.
1619
Tim Peters32a83612006-07-10 21:08:24 +00001620- New function ``sys._current_frames()`` returns a dict mapping thread
1621 id to topmost thread stack frame. This is for expert use, and is
1622 especially useful for debugging application deadlocks. The functionality
1623 was previously available in Fazal Majid's ``threadframe`` extension
1624 module, but it wasn't possible to do this in a wholly threadsafe way from
1625 an extension.

Martin v. Löwis8d656812006-07-10 07:23:48 +00001636 environment variable to be set in order to the SDK environment
1637 for finding the compiler, include files, etc.

1642
Thomas Woutersadd19112006-07-05 11:03:49 +00001643- string.Template() now correctly handles tuple-values. Previously,
1644 multi-value tuples would raise an exception and single-value tuples would
1645 be treated as the value they contain, instead.
1646
Martin v. Löwisede77f52006-07-03 13:01:35 +00001647- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1652
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001653- Bug #1514693: Update turtle's heading when switching between
1654 degrees and radians.
1655
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001656- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001657 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001658
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001659- Bug #1514703: Only setup canvas window in turtle when the canvas
1660 is created.
1661
Martin v. Löwis7596e832006-07-01 15:33:37 +00001662- Bug #1513223: .close() of a _socketobj now releases the underlying
1663 socket again, which then gets closed as it becomes unreferenced.
1664
Fred Drake10497c82006-06-29 02:57:48 +00001665- Bug #1504333: Make sgmllib support angle brackets in quoted
1666 attribute values.
1667
1668- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1669 sgmllib ('[' and ']' were not accepted).
1670
Georg Brandl1be63af2006-06-28 20:23:25 +00001671- Fix a bug in the turtle module's end_fill function.
1672
Brett Cannon53ab5b72006-06-22 16:49:14 +00001673- Bug #1510580: The 'warnings' module improperly required that a Warning
1674 category be either a types.ClassType and a subclass of Warning. The proper
1675 check is just that it is a subclass with Warning as the documentation states.
1676
Georg Brandlad29e632006-06-21 17:45:17 +00001677- The compiler module now correctly compiles the new try-except-finally
1678 statement (bug #1509132).
1679
Neal Norwitz60373cd2006-06-22 06:30:50 +00001680- The wsgiref package is now installed properly on Unix.
1681
Vinay Sajip28e57612006-07-01 10:45:20 +00001682- A bug was fixed in logging.config.fileConfig() which caused a crash on
1683 shutdown when fileConfig() was called multiple times.
1684
Gerhard Häring762fbd32006-07-02 17:48:30 +00001685- The sqlite3 module did cut off data from the SQLite database at the first
1686 null character before sending it to a custom converter. This has been fixed
1687 now.

1690-----------------
1691
Tim Peters112aad32006-07-19 00:03:19 +00001692- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1693 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1694 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001695
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001696- Assigning None to pointer type fields in ctypes structures possible
1697 overwrote the wrong fields, this is fixed now.
1698
1699- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1700 on non-Windows platforms.
1701
1702- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1703 integer or long, without range checking.
1704
1705- Patch #1517790: It is now possible to use custom objects in the ctypes
1706 foreign function argtypes sequence as long as they provide a from_param
1707 method, no longer is it required that the object is a ctypes type.
1708
1709- The '_ctypes' extension module now works when Python is configured
1710 with the --without-threads option.
1711
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001712- Bug #1513646: os.access on Windows now correctly determines write
1713 access, again.
1714
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001715- Bug #1512695: cPickle.loads could crash if it was interrupted with
1716 a KeyboardInterrupt.

Neal Norwitza12aa882006-07-06 06:45:08 +00001718- Bug #1296433: parsing XML with a non-default encoding and
1719 a CharacterDataHandler could crash the interpreter in pyexpat.
1720

1727
Tim Peters32a83612006-07-10 21:08:24 +00001728- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001729 Previously, the slight difference could cause compilation errors of the
1730 'zlib' module on systems with more than one version of zlib.
1731
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001732- The MSI compileall step was fixed to also support a TARGETDIR
1733 with spaces in it.

1763Core and builtins
1764-----------------
1765
Georg Brandla56b9152006-06-19 06:35:54 +00001766- Patch #1507676: Error messages returned by invalid abstract object operations
1767 (such as iterating over an integer) have been improved and now include the
1768 type of the offending object to help with debugging.
1769
Brett Cannonea3912b2006-06-13 21:46:41 +00001770- Bug #992017: A classic class that defined a __coerce__() method that returned
1771 its arguments swapped would infinitely recurse and segfault the interpreter.
1772
Neal Norwitz909eb122006-06-12 02:13:21 +00001773- Fix the socket tests so they can be run concurrently.
1774
Neal Norwitzb9845e72006-06-12 02:11:18 +00001775- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001776 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001777
Brett Cannon22565aa2006-06-09 22:31:23 +00001778- Bug #532646: object.__call__() will continue looking for the __call__
1779 attribute on objects until one without one is found. This leads to recursion
1780 when you take a class and set its __call__ attribute to an instance of the
1781 class. Originally fixed for classic classes, but this fix is for new-style.
1782 Removes the infinite_rec_3 crasher.
1783
Georg Brandl24250812006-06-09 18:45:48 +00001784- The string and unicode methods startswith() and endswith() now accept
1785 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1786
Brett Cannonde3b0522006-06-08 17:00:45 +00001787- Buffer objects, at the C level, never used the char buffer
1788 implementation even when the char buffer for the wrapped object was
1789 explicitly requested (originally returned the read or write buffer).
1790 Now a TypeError is raised if the char buffer is not present but is
1791 requested.
1792
Georg Brandlddbaa662006-06-04 21:56:52 +00001793- Patch #1346214: Statements like "if 0: suite" are now again optimized
1794 away like they were in Python 2.4.
1795
Georg Brandlb7c8f542006-05-27 12:30:25 +00001796- Builtin exceptions are now full-blown new-style classes instead of
1797 instances pretending to be classes, which speeds up exception handling
1798 by about 80% in comparison to 2.5a2.
1799
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001800- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1801 Unicode 4.1.
1802
Georg Brandlf4ef1162006-05-26 18:03:31 +00001803- Patch #921466: sys.path_importer_cache is now used to cache valid and
1804 invalid file paths for the built-in import machinery which leads to
1805 fewer open calls on startup.
1806
Tim Peters696cf432006-05-24 21:10:40 +00001807- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1808 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1809 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1810 the number of input digits (it was and remains linear-time for bases
1811 2, 4, 8, 16 and 32).
1812
Tim Petersb713ec22006-05-23 18:45:30 +00001813- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1814 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1815 an integer close to ``sys.maxint``. This was repaired by patch
1816 #1335972, which also gives a nice speedup.
1817
Richard Jonescebbefc2006-05-23 18:28:17 +00001818- Patch #1337051: reduced size of frame objects.
1819
1820- PyErr_NewException now accepts a tuple of base classes as its
1821 "base" parameter.
1822
Richard Jones7c88dcc2006-05-23 10:37:38 +00001823- Patch #876206: function call speedup by retaining allocated frame
1824 objects.
1825
Georg Brandl7b90e162006-05-18 07:01:27 +00001826- Bug #1462152: file() now checks more thoroughly for invalid mode
1827 strings and removes a possible "U" before passing the mode to the
1828 C library function.
1829
Neal Norwitz1004a532006-05-15 07:17:23 +00001830- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1831
Neal Norwitz373f0a72006-05-15 07:04:36 +00001832- Bug #1487966: Fix SystemError with conditional expression in assignment
1833
Martin v. Löwis879768d2006-05-11 13:28:43 +00001834- WindowsError now has two error code attributes: errno, which carries
1835 the error values from errno.h, and winerror, which carries the error
1836 values from winerror.h. Previous versions put the winerror.h values
1837 (from GetLastError()) into the errno attribute.
1838
Martin v. Löwis77736712006-05-04 05:51:03 +00001839- Patch #1475845: Raise IndentationError for unexpected indent.
1840
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001841- Patch #1479181: split open() and file() from being aliases for each other.
1842
Tim Peters44bd9862006-06-01 13:49:23 +00001843- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1844 methods were always silently ignored by dictionaries when comparing keys.
1845 They are now passed through (except when using the C API function
1846 ``PyDict_GetItem()``, whose semantics did not change).
1847
1848- Bug #1456209: In some obscure cases it was possible for a class with a
1849 custom ``__eq__()`` method to confuse dict internals when class instances
1850 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1851 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001853Extension Modules
1854-----------------
1855
Trent Mick960a3f82006-06-28 20:30:41 +00001856- Bug #1295808: expat symbols should be namespaced in pyexpat
1857
1858- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1859
Brett Cannon6ee7d012006-06-08 16:23:04 +00001860- Change binascii.hexlify to accept a read-only buffer instead of only a char
1861 buffer and actually follow its documentation.
1862
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001863- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1864
Nick Coghlanc649ec52006-05-29 12:43:05 +00001865- Patch #1478788 (modified version): The functional extension module has
1866 been renamed to _functools and a functools Python wrapper module added.
1867 This provides a home for additional function related utilities that are
1868 not specifically about functional programming. See PEP 309.
1869
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001870- Patch #1493701: performance enhancements for struct module.
1871
Georg Brandl378d5922006-05-17 14:26:50 +00001872- Patch #1490224: time.altzone is now set correctly on Cygwin.
1873
Georg Brandl8d3342b2006-05-16 07:38:27 +00001874- Patch #1435422: zlib's compress and decompress objects now have a
1875 copy() method.
1876
Andrew MacIntyre92913322006-06-13 15:04:24 +00001877- Patch #1454481: thread stack size is now tunable at runtime for thread
1878 enabled builds on Windows and systems with Posix threads support.
1879
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001880- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1881 (up to the system limit of 32K characters).
1882
1883- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1884 As a result, these functions now raise WindowsError instead of OSError.
1885
Tim Peters7a822da2006-05-25 21:50:17 +00001886- ``time.clock()`` on Win64 should use the high-performance Windows
1887 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1888 Windows platforms).
1889
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001890- Calling Tk_Init twice is refused if the first call failed as that
1891 may deadlock.
1892
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001893- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1894 accept it without potentially using an uninitialized pointer.
1895
1896- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1897 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1898 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001899
Gregory P. Smith372b5832006-06-05 18:48:21 +00001900- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001901 [pybsddb project SF patch number 1466734]
1902
Gregory P. Smith372b5832006-06-05 18:48:21 +00001903- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1904 parameter is supplied. [SF pybsddb bug #1477863]
1905
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001906- bsddb: the __len__ method of a DB object has been fixed to return correct
1907 results. It could previously incorrectly return 0 in some cases.
1908 Fixes SF bug 1493322 (pybsddb bug 1184012).
1909
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001910- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1911 aborts the db transaction safely when a modifier callback fails.
1912 Fixes SF python patch/bug #1408584.
1913
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001914- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001915 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001916 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1917 database calls that would previously deadlock. [SF python bug #775414]
1918
Vinay Sajip28e57612006-07-01 10:45:20 +00001919- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1925-------
1926
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001927- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1928 functions.
1929
Martin v. Löwis3798da02006-06-17 18:44:27 +00001930- Patch #812986: Update turtle output even if not tracing.
1931
Vinay Sajip28e57612006-07-01 10:45:20 +00001932- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001933 Tkinter.BaseWidget.
1934
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001935- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1936
Martin v. Löwis337487e2006-06-17 09:15:14 +00001937- Patch #763580: Add name and value arguments to Tkinter variable
1938 classes.
1939
Georg Brandl83cc0d02006-06-14 08:50:03 +00001940- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1941 mime.types file for determining MIME types.
1942
Georg Brandl2605ca82006-06-14 06:08:31 +00001943- Bug #1339007: Shelf objects now don't raise an exception in their
1944 __del__ method when initialization failed.
1945
Martin v. Löwisd8251432006-06-14 05:21:04 +00001946- Patch #1455898: The MBCS codec now supports the incremental mode for
1947 double-byte encodings.
1948
Tim Peters43898b42006-06-14 04:09:25 +00001949- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1950 guarantee that adjacent triples in the return list always describe
1951 non-adjacent blocks. Previously, a pair of matching blocks could end
1952 up being described by multiple adjacent triples that formed a partition
1953 of the matching pair.
1954
Greg Ward0e0c9f42006-06-11 16:24:11 +00001955- Bug #1498146: fix optparse to handle Unicode strings in option help,
1956 description, and epilog.
1957
Greg Wardd1c797e2006-06-11 14:42:41 +00001958- Bug #1366250: minor optparse documentation error.
1959
Greg Ward7f547402006-06-11 00:40:49 +00001960- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1961 clarify docs.
1962
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001963- The wsgiref package has been added to the standard library.
1964
Nick Coghlan676725d2006-06-08 13:54:49 +00001965- The functions update_wrapper() and wraps() have been added to the functools
1966 module. These make it easier to copy relevant metadata from the original
1967 function when writing wrapper functions.
1968
Tim Petersd6a9eef2006-06-05 01:48:21 +00001969- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1970 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001971
Martin v. Löwis3f767792006-06-04 19:36:28 +00001972- Patch #1359618: Speed up charmap encoder by using a trie structure
1973 for lookup.
1974
Tim Petersd609b1a2006-06-02 23:22:51 +00001975- The functions in the ``pprint`` module now sort dictionaries by key
1976 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1977 if and only if its display required more than one line, although that
1978 wasn't documented. The new behavior increases predictability; e.g.,
1979 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1980
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001981- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1982 (thanks for J. J. Lee).
1983
Georg Brandl2b330372006-05-28 20:23:12 +00001984- Patch #1496206: improve urllib2 handling of passwords with respect to
1985 default HTTP and HTTPS ports.
1986
George Yoshidaf3c65de2006-05-28 16:39:09 +00001987- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1988
Bob Ippolito7298f272006-05-23 18:43:47 +00001989- Patch #1281707: speed up gzip.readline.
1990
Georg Brandlb89316f2006-05-17 15:51:16 +00001991- Patch #1180296: Two new functions were added to the locale module:
1992 format_string() to get the effect of "format % items" but locale-aware,
1993 and currency() to format a monetary number with currency sign.
1994
Georg Brandle3a25832006-05-17 14:56:04 +00001995- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1996 and several features added, such as speed and geometry control.
1997
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001998- Patch #1488881: add support for external file objects in bz2 compressed
1999 tarfiles.
2000
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002001- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2002 stdout arguments, making it possible to redirect input and output
2003 for remote debugging.
2004
2005- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2006 a couple of issues, notably handling of long file names using the
2007 GNU LONGNAME extension.
2008
2009- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2010 new flag when ``name`` is already the name of an option flag.
2011
2012- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2013 package.
2014
2015- Patch #1472854: make the rlcompleter.Completer class usable on non-
2016 UNIX platforms.
2017
2018- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
2019
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00002020- Bug #1472827: correctly escape newlines and tabs in attribute values in
2021 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002051What's New in Python 2.5 alpha 2?
2052=================================
2053
2054*Release date: 27-APR-2006*
2055
2056Core and builtins
2057-----------------
2058
Thomas Heller1b046642006-04-18 18:51:06 +00002059- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2060 by converting these apis from macros into exported functions again:
2061
2062 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2063 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2064 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2065 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2066 PyRun_String Py_CompileString
2067
Martin v. Löwis45294a92006-04-18 06:24:08 +00002068- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2069
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002070- All uses of PyStructSequence_InitType have been changed to initialize
2071 the type objects only once, even if the interpreter is initialized
2072 multiple times.
2073
Neal Norwitz61546162006-04-14 05:20:28 +00002074- Bug #1454485, array.array('u') could crash the interpreter. This was
2075 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2076 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2077
2078- Py_UNICODE is unsigned. It was always documented as unsigned, but
2079 due to a bug had a signed value in previous versions.
2080
Tim Peters3a5e8b12006-04-11 01:44:07 +00002081- Patch #837242: ``id()`` of any Python object always gives a positive
2082 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2083 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002084 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002085 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002086
Tim Peters3a5e8b12006-04-11 01:44:07 +00002087 def __hash__(self):
2088 return id(self) # WRONG
2089
2090 because a hash result must be a (short) Python int but it was always
2091 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002092 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002093 was always usable as a hash value before this patch. That's no longer
2094 necessarily so.
2095
2096- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002097 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002098 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002099 #1454844)
2100
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002101- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2102 involving generators that have paused outside of any ``try`` or ``with``
2103 blocks. (In 2.5a1, a paused generator that was part of a reference
2104 cycle could not be garbage collected, regardless of whether it was
2105 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00002106
Anthony Baxter51bcb682006-04-05 14:51:42 +00002107Extension Modules

2109
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00002110- Patch #1191065: Fix preprocessor problems on systems where recvfrom
2111 is a macro.
2112
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002113- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2114 fails with an error condition.
2115
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002116- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2117
2118- Bug #1117761: bsddb.*open() no longer raises an exception when using
2119 the cachesize parameter.
2120
2121- Bug #1149413: bsddb.*open() no longer raises an exception when using
2122 a temporary db (file=None) with the 'n' flag to truncate on open.
2123
2124- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2125 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002126
Armin Rigoa9017c32006-04-19 11:50:27 +00002127- Patch #1062014: AF_UNIX sockets under Linux have a special
2128 abstract namespace that is now fully supported.
2129
Anthony Baxter51bcb682006-04-05 14:51:42 +00002130Library
2131-------
2132
Peter Astrand7d1d4362006-07-14 14:04:45 +00002133- Bug #1223937: subprocess.CalledProcessError reports the exit status
2134 of the process using the returncode attribute, instead of
2135 abusing errno.
2136
Tim Peters711bf302006-04-25 03:31:36 +00002137- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2138 a doctest to be skipped (the code is not run, and the expected output
2139 or exception is ignored).
2140
Nick Coghlanda2268f2006-04-24 04:37:15 +00002141- Fixed contextlib.nested to cope with exceptions being raised and
2142 caught inside exit handlers.
2143
Greg Wardab05edc2006-04-23 03:47:58 +00002144- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2145 hex, octal, or binary; add ``append_const`` action; keep going if
2146 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2147 added ``epilog`` for better help generation).
2148
Tim Peters21fbd572006-04-21 21:18:10 +00002149- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2150 called from a thread spawned as a side effect of importing a module.
2151
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002152- The pydoc module now supports documenting packages contained in
2153 .zip or .egg files.
2154
2155- The pkgutil module now has several new utility functions, such
2156 as ``walk_packages()`` to support working with packages that are either
2157 in the filesystem or zip files.
2158
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002159- The mailbox module can now modify and delete messages from
2160 mailboxes, in addition to simply reading them. Thanks to Gregory
2161 K. Johnson for writing the code, and to the 2005 Google Summer of
2162 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002163
Tim Petersc7605f22006-04-17 21:12:33 +00002164- The ``__del__`` method of class ``local`` in module ``_threading_local``
2165 returned before accomplishing any of its intended cleanup.
2166
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002167- Patch #790710: Add breakpoint command lists in pdb.
2168
Martin v. Löwis0db2a982006-04-16 20:55:38 +00002169- Patch #1063914: Add Tkinter.Misc.clipboard_get().
2170
Martin v. Löwis4b501e62006-04-15 08:41:11 +00002171- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
2172
Anthony Baxtere29002c2006-04-12 12:07:31 +00002173- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2174 Windows. Bug #1469163.
2175
Phillip J. Eby47032112006-04-11 01:07:43 +00002176- The warnings, linecache, inspect, traceback, site, and doctest modules
2177 were updated to work correctly with modules imported from zipfiles or
2178 via other PEP 302 __loader__ objects.
2179
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002180- Patch #1467770: Reduce usage of subprocess._active to processes which
2181 the application hasn't waited on.
2182
Martin v. Löwisb04dee92006-04-10 08:34:21 +00002183- Patch #1462222: Fix Tix.Grid.
2184
Neal Norwitza31bf182006-04-09 03:35:43 +00002185- Fix exception when doing glob.glob('anything*/')
2186
Skip Montanaro262fb922006-04-21 02:31:07 +00002187- The pstats.Stats class accepts an optional stream keyword argument to
2188 direct output to an alternate file-like object.
2189
Anthony Baxter51bcb682006-04-05 14:51:42 +00002190Build
2191-----
2192
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002193- The Makefile now has a reindent target, which runs reindent.py on
2194 the library.
2195
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002196- Patch #1470875: Building Python with MS Free Compiler
2197
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002198- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002199
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002200- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2201 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002202 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002203 CXX from --with-cxx-main, see description in README.
2204
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002205- Patch #1429775: Link extension modules with the shared libpython.
2206
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002207- Fixed a libffi build problem on MIPS systems.
2208
Tim Peters8931ff12006-05-13 23:28:20 +00002209- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2210 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2211 and "%zu" for unsigned integers of type ``size_t``.
2212
Anthony Baxter51bcb682006-04-05 14:51:42 +00002213Tests
2214-----
2215
Nick Coghlanda2268f2006-04-24 04:37:15 +00002216- test_contextlib now checks contextlib.nested can cope with exceptions
2217 being raised and caught inside exit handlers.
2218
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002219- test_cmd_line now checks operation of the -m and -c command switches
2220
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002221- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2222 it separately and by hand. It also wasn't cleaning up its changes to
2223 the current Decimal context.
2224
Thomas Woutersabd08882006-04-26 15:53:30 +00002225- regrtest.py now has a -M option to run tests that test the new limits of
2226 containers, on 64-bit architectures. Running these tests is only sensible
2227 on 64-bit machines with more than two gigabytes of memory. The argument
2228 passed is the maximum amount of memory for the tests to use.
2229
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00002230Tools
2231-----
2232
2233- Added the Python benchmark suite pybench to the Tools/ directory;
2234 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002236Documentation
2237-------------
2238
Tim Petersb06d28c2006-05-12 01:57:59 +00002239- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2240
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002241- PEP 343: Added Context Types section to the library reference
2242 and attempted to bring other PEP 343 related documentation into
2243 line with the implementation and/or python-dev discussions.
2244
Tim Peters8dc73d22006-04-24 02:03:16 +00002245- Bug #1337990: clarified that ``doctest`` does not support examples
2246 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +00002247

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002249What's New in Python 2.5 alpha 1?
2250=================================
2251
Anthony Baxterebed3f62006-04-03 15:03:44 +00002252*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002253
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002254Core and builtins
2255-----------------
2256
Nick Coghlan43832302006-04-23 17:04:07 +00002257- PEP 338: -m command line switch now delegates to runpy.run_module
2258 allowing it to support modules in packages and zipfiles
2259
Martin v. Löwisc661b882006-04-20 04:54:23 +00002260- On Windows, .DLL is not an accepted file name extension for
2261 extension modules anymore; extensions are only found if they
2262 end in .PYD.
2263
Martin v. Löwisea62d252006-04-03 10:56:49 +00002264- Bug #1421664: sys.stderr.encoding is now set to the same value as
2265 sys.stdout.encoding.
2266
Neal Norwitz92e212f2006-04-03 04:48:37 +00002267- __import__ accepts keyword arguments.
2268
Georg Brandlccadf842006-03-31 18:54:53 +00002269- Patch #1460496: round() now accepts keyword arguments.
2270
Anthony Baxter262c00a2006-03-30 10:53:17 +00002271- Fixed bug #1459029 - unicode reprs were double-escaped.
2272
Hye-Shik Changd478f342006-03-23 12:32:36 +00002273- Patch #1396919: The system scope threads are reenabled on FreeBSD
2274 5.4 and later versions.
2275
Neal Norwitze98ccf62006-03-23 05:39:47 +00002276- Bug #1115379: Compiling a Unicode string with an encoding declaration
2277 now gives a SyntaxError.
2278
Georg Brandlabd1ff82006-03-18 07:59:59 +00002279- Previously, Python code had no easy way to access the contents of a
2280 cell object. Now, a ``cell_contents`` attribute has been added
2281 (closes patch #1170323).
2282
Tim Peterscf79aac2006-03-16 01:14:46 +00002283- Patch #1123430: Python's small-object allocator now returns an arena to
2284 the system ``free()`` when all memory within an arena becomes unused
2285 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2286 freed. Some applications will see a drop in virtual memory size now,
2287 especially long-running applications that, from time to time, temporarily
2288 use a large number of small objects. Note that when Python returns an
2289 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002290 platform C library will in turn return that memory to the operating system.
2291 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002292 appears to be effective at least on Microsoft C and gcc-based systems.
2293 Thanks to Evan Jones for hard work and patience.
2294
Georg Brandl533ff6f2006-03-08 18:09:27 +00002295- Patch #1434038: property() now uses the getter's docstring if there is
2296 no "doc" argument given. This makes it possible to legitimately use
2297 property() as a decorator to produce a read-only property.
2298
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002299- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2300 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2301 of requiring an int or long in slicing and a few other contexts, enabling
2302 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2303
Neal Norwitz995acdf2006-03-07 05:01:00 +00002304- Fixed various bugs reported by Coverity's Prevent tool.
2305
Brett Cannonbf364092006-03-01 04:25:17 +00002306- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2307 new exception base class, BaseException, which has a new message attribute.
2308 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2309 Raising a string exception now raises a DeprecationWarning.
2310
Thomas Woutersfb609f42006-02-28 16:37:25 +00002311- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2312 explicitly relative, using 'from .module import name' to mean 'from the same
2313 package as this module is in. Imports without dots still default to the
2314 old relative-then-absolute, unless 'from __future__ import
2315 absolute_import' is used.
2316
Brett Cannona7446e32006-02-27 23:39:10 +00002317- Properly check if 'warnings' raises an exception (usually when a filter set
2318 to "error" is triggered) when raising a warning for raising string
2319 exceptions.
2320
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002321- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002322 The name was removed from Include/code.h.
2323
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002324- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002325
Guido van Rossum1968ad32006-02-25 22:38:04 +00002326- Patch 1433928:
2327 - The copy module now "copies" function objects (as atomic objects).
2328 - dict.__getitem__ now looks for a __missing__ hook before raising
2329 KeyError.
2330
Tim Peters84ef21c2006-02-28 20:39:06 +00002331- PEP 343: with statement implemented. Needs ``from __future__ import
2332 with_statement``. Use of 'with' as a variable will generate a warning.
2333 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002334 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002335 The following objects have __context__ methods:
2336 - The built-in file type.
2337 - The thread.LockType type.
2338 - The following types defined by the threading module:
2339 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2340 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002341
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002342- Fix the encodings package codec search function to only search
2343 inside its own package. Fixes problem reported in patch #1433198.
2344
2345 Note: Codec packages should implement and register their own
2346 codec search function. PEP 100 has the details.
2347
Tim Peters9ea89d22006-06-04 03:26:02 +00002348- PEP 353: Using ``Py_ssize_t`` as the index type.
2349
2350- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2351 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2352 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2353 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2354 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002355
Neal Norwitzfc76d632006-01-10 06:03:13 +00002356- Patch #1400181, fix unicode string formatting to not use the locale.
2357 This is how string objects work. u'%f' could use , instead of .
2358 for the decimal point. Now both strings and unicode always use periods.
2359
Neal Norwitz671b9e32006-01-09 07:07:12 +00002360- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2361 configure would break checking curses.h.
2362
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002363- Bug #959576: The pwd module is now builtin. This allows Python to be
2364 built on UNIX platforms without $HOME set.
2365
Neal Norwitzc10978f2005-12-19 06:07:16 +00002366- Bug #1072182, fix some potential problems if characters are signed.
2367
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002368- Bug #889500, fix line number on SyntaxWarning for global declarations.
2369
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002370- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2371
Neal Norwitze7214a12005-12-18 05:03:17 +00002372- Support for converting hex strings to floats no longer works.
2373 This was not portable. float('0x3') now raises a ValueError.
2374
Barry Warsaw2a38a862005-12-18 01:27:35 +00002375- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002376 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002377 is now displayed in interactive prompt banner.
2378
Georg Brandlfa166682005-12-17 21:45:17 +00002379- Implementation of PEP 341 - Unification of try/except and try/finally.
2380 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002381 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002382
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002383- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2384 now encodes backslash correctly.
2385
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002386- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2387
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002388- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002389 and long longs.
2390
Neal Norwitz67715f02005-11-09 06:59:35 +00002391- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002392 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002393 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002394
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002395- Replaced most Unicode charmap codecs with new ones using the
2396 new Unicode translate string feature in the builtin charmap
2397 codec; the codecs were created from the mapping tables available
2398 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2399 encodings now include a mapping for the Apple logo)
2400
Tim Peterse3547fd2005-12-16 23:13:57 +00002401- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002402
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002403- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002404
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002405- A new AST parser implementation was completed. The abstract
2406 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002407 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002408
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002409- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002410 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2411
Neal Norwitz708e51a2005-10-03 04:48:15 +00002412- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2413
Neal Norwitz11bd1192005-10-03 00:54:56 +00002414- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2415 Provide a warning when a directory is passed on the command line.
2416
Neal Norwitz40d37812005-10-02 01:48:49 +00002417- Fix segfault with invalid coding.
2418
2419- SF bug #772896: unknown encoding results in MemoryError.
2420
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002421- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002422 supported a __len__() method which evaluated to False when the iterator
2423 was empty.
2424
Guido van Rossum630db602005-09-20 18:49:54 +00002425- On 64-bit platforms, when __len__() returns a value that cannot be
2426 represented as a C int, raise OverflowError.
2427
Skip Montanarof8948ca2005-09-19 03:54:46 +00002428- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002429 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002430
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002431- SF bug #893549: parsing keyword arguments was broken with a few format
2432 codes.
2433
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002434- Changes donated by Elemental Security to make it work on AIX 5.3
2435 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2436 bug #105470: test_pwd fails on 64bit system (Opteron).
2437
Guido van Rossum539c6622005-09-14 17:49:54 +00002438- Changes donated by Elemental Security to make it work on HP-UX 11 on
2439 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2440
Georg Brandl4550b8d2005-08-26 06:43:52 +00002441- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002442 (fixes bug #1119418).
2443
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002444- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2445
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002446- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2447 exceptions that cause a function to exit.
2448
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002449- The implementation of set() and frozenset() was revised to use its
2450 own internal data structure. Memory consumption is reduced by 1/3
2451 and there are modest speed-ups as well. The API is unchanged.
2452
Tim Petersde7990b2005-07-17 23:45:23 +00002453- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2454
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002455- SF bug #1229429: PyObject_CallMethod failed to decrement some
2456 reference counts in some error exit cases.
2457
Tim Petersecc6e6a2005-07-10 22:30:55 +00002458- SF bug #1185883: Python's small-object memory allocator took over
2459 a block managed by the platform C library whenever a realloc specified
2460 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002461 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002462 portable way to copy data from the C-managed block into Python's
2463 small-object space without risking a memory fault. Python's small-object
2464 realloc now leaves such blocks under the control of the platform C
2465 realloc.
2466
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002467- SF bug #1232517: An overflow error was not detected properly when
2468 attempting to convert a large float to an int in os.utime().
2469
Raymond Hettinger3296e692005-06-29 23:29:56 +00002470- SF bug #1224347: hex longs now print with lowercase letters just
2471 like their int counterparts.
2472
Michael W. Hudson188d4362005-06-20 16:52:57 +00002473- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2474 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2475 interpreter states; back out that fix and do a better job (see
2476 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2477 for a longer write-up of the problem).
2478
Michael W. Hudsondf888462005-06-03 14:41:55 +00002479- SF patch #1180995: marshal now uses a binary format by default when
2480 serializing floats.
2481
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002482- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2483 the routines that promise to produce IEEE 754 binary representations
2484 of floats now simply copy bytes around.
2485
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002486- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2487 278.
2488
Brett Cannonc3647ac2005-04-26 03:45:26 +00002489- patch #1109424: int, long, float, complex, and unicode now check for the
2490 proper magic slot for type conversions when subclassed. Previously the
2491 magic slot was ignored during conversion. Semantics now match the way
2492 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002493 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002494 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002495 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002496
Barry Warsawc8d907c2005-04-19 23:43:40 +00002497- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2498 NULL, now raise an AttributeError when attempting to set or delete the
2499 attribute. Previously a TypeError was raised, but this was inconsistent
2500 with the equivalent pure-Python implementation.
2501
Michael W. Hudson774479c2005-04-18 08:46:17 +00002502- It is now safe to call PyGILState_Release() before
2503 PyEval_InitThreads() (note that if there is reason to believe there
2504 are multiple threads around you still must call PyEval_InitThreads()
2505 before using the Python API; this fix is for extension modules that
2506 have no way of knowing if Python is multi-threaded yet).
2507
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002508- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2509 disabled caused a crash.
2510
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002511- Bug #1165306: instancemethod_new allowed the creation of a method
2512 with im_class == im_self == NULL, which caused a crash when called.
2513
Tim Petersecc6e6a2005-07-10 22:30:55 +00002514- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002515 fixes the crash seen in bug #1165761
2516
Raymond Hettinger96229b12005-03-11 06:49:40 +00002517- Added two new builtins, any() and all().
2518
Brett Cannon409d8f22005-03-05 06:47:57 +00002519- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002520 (e.g., ``class C(): pass`` is no longer a syntax error).
2521 Patch #1176012 added support to the 'parser' module and 'compiler' package
2522 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002523
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002524- Patch #1115086: Support PY_LONGLONG in structmember.
2525
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002526- Bug #1155938: new style classes did not check that __init__() was
2527 returning None.
2528
Tim Petersecc6e6a2005-07-10 22:30:55 +00002529- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002530 ('\') with a specific error message.
2531
Martin v. Löwisff232d72005-03-03 09:24:38 +00002532- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2533
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002534- Bug #1124295: the __name__ attribute of file objects was
2535 inadvertently made inaccessible in restricted mode.
2536
Tim Petersecc6e6a2005-07-10 22:30:55 +00002537- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002538 an ferror() call.
2539
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002540- min() and max() now support key= arguments with the same meaning as in
2541 list.sort().
2542
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002543- The peephole optimizer now performs simple constant folding in expressions:
2544 (2+3) --> (5).
2545
Raymond Hettingera422c342005-01-11 03:03:27 +00002546- set and frozenset objects can now be marshalled. SF #1098985.
2547
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002548- Bug #1077106: Poor argument checking could cause memory corruption
2549 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002550
Jeremy Hyltonab630502005-02-04 18:44:06 +00002551- The parser did not complain about future statements in illegal
2552 positions. It once again reports a syntax error if a future
2553 statement occurs after anything other than a doc string.
2554
Neil Schemenauercf52c072005-08-12 17:34:58 +00002555- Change the %s format specifier for str objects so that it returns a
2556 unicode instance if the argument is not an instance of basestring and
2557 calling __str__ on the argument returns a unicode instance.
2558
Tim Petersf4e69282006-02-27 17:15:31 +00002559- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2560 current thread state when the auto-GIL-state machinery knows about
2561 it (since the thread state is being deleted, continuing to remember it
2562 can't help, but can hurt if another thread happens to get created with
2563 the same thread id).
2564
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002565Extension Modules
2566-----------------
2567
Georg Brandl43f08a82006-03-31 18:01:16 +00002568- Patch #1380952: fix SSL objects timing out on consecutive read()s
2569
Neal Norwitz05a45592006-03-20 06:30:08 +00002570- Patch #1309579: wait3 and wait4 were added to the posix module.
2571
Anthony Baxterfa869072006-03-20 05:21:58 +00002572- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2573 In addition, the existing ulaw code was updated.
2574
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002575- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002576 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002577
Neal Norwitz10be10c2006-03-16 06:50:13 +00002578- Everything under lib-old was removed. This includes the following modules:
2579 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002580 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002581 util, whatsound, whrandom, zmod
2582
2583- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2584
2585- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002586 is deprecated. The undocumented re.engine variable no longer exists.
2587
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002588- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2589 SS2 (single-shift 2) escape sequences correctly.
2590
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002591- The unicodedata module was updated to the 4.1 version of the Unicode
2592 database. The 3.2 version is still available as unicodedata.db_3_2_0
2593 for applications that require this specific version (such as IDNA).
2594
Neal Norwitzb62c4332006-03-04 18:35:47 +00002595- The timing module is no longer built by default. It was deprecated

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002755- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2756 been renamed to have only a single underscore prefix. This was done to
2757 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002758
Nick Coghlan43832302006-04-23 17:04:07 +00002759- PEP 338: new module runpy defines a run_module function to support
2760 executing modules which provide access to source code or a code object
2761 via the PEP 302 import mechanisms.
2762
Anthony Baxter93f5b932006-04-03 08:05:07 +00002763- The email module's parsedate_tz function now sets the daylight savings

2771 in attribute values.
2772
Anthony Baxterc51ee692006-04-01 00:57:31 +00002773- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002774 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002775 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002776 module will not be built.
2777
Tim Petersc17976e2006-04-01 00:26:53 +00002778- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2779 aren't officially supported here, and trying to use them will probably
2780 raise an exception some day. But dicts have been allowed, and "mostly
2781 worked", so support for them won't go away without warning.
2782
Georg Brandl338ef7d2006-03-31 18:42:16 +00002783- Bug #1445068: getpass.getpass() can now be given an explicit stream
2784 argument to specify where to write the prompt.
2785

2801
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002802- email 4.0 package now integrated. This is largely the same as the email 3.0
2803 package that was included in Python 2.3, except that PEP 8 module names are
2804 now used (e.g. mail.message instead of email.Message). The MIME classes
2805 have been moved to a subpackage (e.g. email.mime.text instead of
2806 email.MIMEText). The old names are still supported for now. Several
2807 deprecated Message methods have been removed and lots of bugs have been
2808 fixed. More details can be found in the email package documentation.
2809
Walter Dörwald40108c92006-03-27 08:15:44 +00002810- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2811 (a subclass of tuple) that provides incremental decoders and encoders
2812 (a way to use stateful codecs without the stream API). Python functions
2813 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2814 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2815 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002817- Patch #1359365: Calling next() on a closed StringIO.String object raises
2818 a ValueError instead of a StopIteration now (like file and cString.String do).
2819 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2820 called before (like file and StringIO.StringIO do).

Tim Petersda1329b2006-02-27 16:50:01 +00002869- Patch #1349118: urllib now supports user:pass@ style proxy
Martin v. Löwis3e865952006-01-24 15:51:21 +00002870 specifications, raises IOErrors when proxies for unsupported protocols
2871 are defined, and uses the https proxy on https redirections.

2888
Neal Norwitz338e7862005-12-23 21:27:46 +00002889- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2890 LoadError as documented, instead of IOError. For compatibility,
2891 LoadError subclasses IOError.
2892
Brett Cannon3cbd0382005-12-16 22:49:23 +00002893- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002894 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2895 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2896 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2897 Ronald L. Rivest offered this advice for Python:
2898
2899 "The consensus of researchers in this area (at least as
2900 expressed at the NIST Hash Function Workshop 10/31/05),
2901 is that SHA-256 is a good choice for the time being, but
2902 that research should continue, and other alternatives may
2903 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002904
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002905- Added a subset of Fredrik Lundh's ElementTree package. Available

2958 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002959 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002960

2982 to W3C name (404 -> 'Not Found'). RFE #1216944.
2983
Georg Brandl9e43acf2005-07-04 17:16:07 +00002984- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2985 as this can cause problems with apps closing all file descriptors.

2998 Bug #1224621.
2999
Raymond Hettinger68c04532005-06-10 11:05:19 +00003000- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00003001 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00003002 the generate_tokens() function now accepts a callable argument that
3003 terminates by raising StopIteration.
3004
Georg Brandl9166e1a2005-06-04 09:20:03 +00003005- Bug #1196315: fix weakref.WeakValueDictionary constructor.

3020
Raymond Hettinger267b8682005-03-27 10:47:39 +00003021- decimal operator and comparison methods now return NotImplemented
3022 instead of raising a TypeError when interacting with other types. This
3023 allows other classes to implement __radd__ style methods and have them
3024 work as expected.
3025
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003026- Bug #1163325: Decimal infinities failed to hash. Attempting to

Guido van Rossumd0641422005-02-03 15:01:24 +00003064- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3065 disables recursive traversal through instance attributes, which can
3066 be exploited in various ways.
3067
Tim Peterse3547fd2005-12-16 23:13:57 +00003068- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003069 flags on the HTTP listening socket.
3070

3080
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003081- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3082
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003083- Enhancements to the csv module:
3084
3085 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003086 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003087 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003088 + Dialect parameter parsing has been re-implemented to improve error
3089 reporting.
3090 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3091 dictates.
3092 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003093 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003094 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003095 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3096 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003097 + reader now allows \r characters to be quoted (previously it only allowed
3098 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003099 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003100 + Dialect classes passed to the module are no longer instantiated by
3101 the module before being parsed (the former validation scheme required
3102 this, but the mechanism was unreliable).
3103 + The dialect registry now contains instances of the internal
3104 C-coded dialect type, rather than references to python objects.
3105 + the internal c-coded dialect type is now immutable.
3106 + register_dialect now accepts the same keyword dialect specifications
3107 as the reader and writer, allowing the user to register dialects
3108 without first creating a dialect class.
3109 + a configurable limit to the size of parsed fields has been added -
3110 previously, an unmatched quote character could result in the entire
3111 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003112 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003113 the parser field size limit (returning the former limit). The initial
3114 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003115 + A line_num attribute has been added to the reader object, which tracks
3116 the number of lines read from the source iterator. This is not
3117 the same as the number of records returned, as records can span
3118 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003119 + reader and writer objects were not being registered with the cyclic-GC.
3120 This has been fixed.
3121
Brett Cannone6539c42005-01-08 02:43:53 +00003122- _DummyThread objects in the threading module now delete self.__block that is
3123 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3124 lock primitives tend to be limited in number and thus should not be wasted on
3125 a _DummyThread object. Fixes bug #1089632.
3126
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003127- The imghdr module now detects Exif files.
3128
Raymond Hettinger6065d322004-12-20 23:51:53 +00003129- StringIO.truncate() now correctly adjusts the size attribute.
3130 (Bug #951915).
3131
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003132- locale.py now uses an updated locale alias table (built using
3133 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3134 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003135 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003136
Raymond Hettinger3557f422004-12-07 12:02:02 +00003137- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3138
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003139- the pickle module no longer accepts the deprecated None option in the
3140 args tuple returned by __reduce__().
3141
Brett Cannon84667c02004-12-07 03:25:18 +00003142- optparse now optionally imports gettext. This allows its use in setup.py.
3143
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003144- the pickle module no longer uses the deprecated bin parameter.
3145
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003146- the shelve module no longer uses the deprecated binary parameter.
3147
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003148- the pstats module no longer uses the deprecated ignore() method.
3149
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003150- the filecmp module no longer uses the deprecated use_statcache argument.
3151
Raymond Hettinger664347b2004-12-04 21:21:53 +00003152- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3153 extended or overridden by subclasses. Formerly, the subclassed method would
3154 be ignored by the rest of the module. (Bug #1078905).
3155
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003156- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003157 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003158
Walter Dörwald36733692004-12-22 12:50:50 +00003159- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3160 once when a size argument is given. This prevents a buffer overflow in the
3161 tokenizer with very long source lines.
3162
Barry Warsaw538561e2006-01-01 21:48:54 +00003163- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3164 immediately after creating the object, without any intervening
3165 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003166
Skip Montanaro05885812005-01-16 20:48:27 +00003167- The reconvert.quote function can now emit triple-quoted strings. The
3168 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003169
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003170- ``UserString.MutableString`` now supports negative indices in
3171 ``__setitem__`` and ``__delitem__``
3172
Greg Ward40407942005-03-05 02:53:17 +00003173- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3174 correctly.
3175
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003176- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3177 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3178 character even if the user has passed a size parameter to get a proper
3179 line ending. Remove the special handling of a "\r\n" that has been split
3180 between two lines.
3181
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003182- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3183 about illegal code points. The codec now supports PEP 293 style error
3184 handlers.
3185
Walter Dörwald78a78b02005-09-01 12:04:29 +00003186- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003187 from the input stream, so that the output is a byte string in the correct
3188 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003189
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003190- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3191 considering it exactly like a '*'.
3192
Walter Dörwald007f8df2005-10-09 19:42:27 +00003193- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3194 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003195
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003196- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3197
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003198- Patch #1413711: Certain patterns of differences were making difflib
3199 touch the recursion limit.
3200
Walter Dörwald58917a62006-03-31 15:26:22 +00003201- Bug #947906: An object oriented interface has been added to the calendar
3202 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003203 called as a script (e.g. via ``python -mcalendar``). Localized month and
3204 weekday names can be ouput (even if an exotic encoding is used) using
3205 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003206
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003207Build
3208-----
3209
Neal Norwitz602d3392006-03-31 08:21:40 +00003210- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3211 by using -mieee gcc option.
3212
Martin v. Löwis86d66262006-02-17 08:40:11 +00003213- Patch #1432345: Make python compile on DragonFly.
3214
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003215- Build support for Win64-AMD64 was added.
3216
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003217- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3218
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003219- Patch #881820: look for openpty and forkpty also in libbsd.
3220
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003221- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3222 The zlib module is now builtin on Windows.
3223
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003224- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3225
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003226- Bug #1189330: configure did not correctly determine the necessary
3227 value of LINKCC if python was built with GCC 4.0.
3228
Trent Mick8321b422005-07-26 02:29:21 +00003229- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3230 vulnerability in zlib 1.2.1 and 1.2.2.
3231
Brett Cannon08cd5982005-04-24 22:26:38 +00003232- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3233 flags that change binary compatibility. Changes were also made to
3234 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003235 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003236
Bob Ippolitoed233462005-03-29 13:47:59 +00003237- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3238 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3239 no longer exists). This configure patch makes things right.
3240
Martin v. Löwise2713be2005-03-08 15:03:08 +00003241- Bug #1158607: Build with --disable-unicode again.
3242
Brett Cannon46d96232005-02-16 00:07:19 +00003243- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3244 defined. Discovered as a result of not being able to build on OS X.
3245
Brett Cannon516592f2004-12-07 00:42:59 +00003246- setup.py now uses the directories specified in LDFLAGS using the -L option
3247 and in CPPFLAGS using the -I option for adding library and include
3248 directories, respectively, for compiling extension modules against. This has
3249 led to the core being compiled using the values in CPPFLAGS. It also removes
3250 the need for the special-casing of both DarwinPorts and Fink for darwin since
3251 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3252 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3253 Fink, ``-I/opt/local/include`` for DarwinPorts).
3254
Brett Cannon43802422005-02-10 20:48:03 +00003255- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3256 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3257 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3258 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003260C API
3261-----
3262
Tim Petersc9d78aa2006-03-26 23:27:58 +00003263- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3264 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3265 is obtained via the ``PyObject_`` family, it must be released via the
3266 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3267 always been officially true, but when Python's small-object allocator was
3268 introduced, an attempt was made to cater to a few extension modules
3269 discovered at the time that obtained memory via ``PyObject_New`` but
3270 released it via ``PyMem_DEL``. It's years later, and if such code still
3271 exists it will fail now (probably with segfaults, but calling wrong
3272 low-level memory management functions can yield many symptoms).
3273
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003274- Added a C API for set and frozenset objects.
3275
Raymond Hettinger66517482004-12-03 11:45:13 +00003276- Removed PyRange_New().
3277
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003278- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3279 mapping argument now. This string is used as a mapping table. Byte values
3280 greater than the length of the string and 0xFFFE are treated as undefined
3281 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003288
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003289- Patch #1276356: New resource "urlfetch" is implemented. This enables
