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

76
Robert Schuppenies78813dc2008-08-10 11:19:25 +000077- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
78 menu entries were not deleted.
79
Martin v. Löwisc7af7f32008-08-02 07:21:06 +000080- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
81
Brett Cannonff931572008-07-13 01:20:19 +000082- Issue #3339: dummy_thread.acquire() could return None which is not a valid

91 handlers that derive the same default base class.
92
Amaury Forgeot d'Arc198e3532008-03-27 23:41:59 +000093- Issue #2495: tokenize.untokenize now inserts a space between two consecutive
94 string literals; previously, ["" ""] was rendered as [""""], which is
95 incorrect python code.
96
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +000097- Issue #2482: Make sure that the coefficient of a Decimal is always
98 stored as a str instance, not as a unicode instance. This ensures
99 that str(Decimal) is always an instance of str. This fixes a
100 regression from Python 2.5.1 to Python 2.5.2.
101
Mark Dickinson26c25d92008-03-25 14:35:25 +0000102- Issue #2478: fix failure of decimal.Decimal(0).sqrt()

Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000119 calling .read() on a socket object wrapped with makefile().
Andrew M. Kuchling664553a2008-02-23 19:30:59 +0000120
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +0000121- Bug #1433694: minidom's .normalize() failed to set .nextSibling for

125 stdout and stderr fds rather than leaving them open until the
126 instance is destroyed.
127
Gregory P. Smithf8f30fa2008-07-06 04:04:07 +0000128- Issue #2632: Prevent socket.read(bignumber) from over allocating memory
129 in the common case when the data is returned from the underlying socket
130 in increments much smaller than bignumber.
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +0000131
Gregory P. Smithb4bc9b92008-08-04 00:15:54 +0000132- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
133 argument in python 2.5, this broke code that subclassed Popen to include its
134 own poll method. Fixed my moving _deadstate to an _internal_poll method.
135

204
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000205- Issue #1920: "while 0" statements were completely removed by the compiler,
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000206 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000207 the condition is false. Now the compiler correctly emits bytecode for the
208 "else" suite.

Neal Norwitzff4b63b2006-08-04 04:50:21 +00001164
1165Core and builtins
1166-----------------
1167
Neal Norwitz24b6f202006-09-05 04:43:56 +00001168- Fix infinite recursion when subclassing long and overriding __hash__.
1169
1170- Fix concatenation (+=) of long strings.
1171
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001172- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001173 compared equal or unequal to a string and a UnicodeDecodeError
1174 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001175
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001176 Instead, the equal (==) and unequal (!=) comparison operators will
1177 now issue a UnicodeWarning and interpret the two objects as
1178 unequal. The UnicodeWarning can be filtered as desired using
1179 the warning framework, e.g. silenced completely, turned into an
1180 exception, logged, etc.
1181
1182 Note that compare operators other than equal and unequal will still
1183 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001184
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001185- Fix segfault when doing string formatting on subclasses of long.
1186
1187- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1188 with new-style classes.
1189
1190- Fix bug related to __len__ functions returning negative values with
1191 classic classes.
1192
1193- Patch #1538606, Fix __index__() clipping. There were some problems
1194 discovered with the API and how integers that didn't fit into Py_ssize_t
1195 were handled. This patch attempts to provide enough alternatives
1196 to effectively use __index__.
1197
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001198- Bug #1536021: __hash__ may now return long int; the final hash
1199 value is obtained by invoking hash on the long int.
1200
Thomas Hellerab1049c2006-08-08 17:37:00 +00001201- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1202
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001203- Bug #1535165: fixed a segfault in input() and raw_input() when
1204 sys.stdin is closed.
1205
Thomas Heller74d36f02006-08-04 18:17:40 +00001206- On Windows, the PyErr_Warn function is now exported from
1207 the Python dll again.
1208
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001209- Bug #1191458: tracing over for loops now produces a line event
1210 on each iteration. Fixing this problem required changing the .pyc
1211 magic number. This means that .pyc files generated before 2.5c1
1212 will be regenerated.
1213
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001214- Bug #1333982: string/number constants were inappropriately stored
1215 in the byte code and co_consts even if they were not used, ie
1216 immediately popped off the stack.
1217
Georg Brandle9462c72006-08-04 18:03:37 +00001218- Fixed a reference-counting problem in property().
1219
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001220
1221Library
1222-------
1223
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001224- Fix a bug in the ``compiler`` package that caused invalid code to be
1225 generated for generator expressions.
1226
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001227- The distutils version has been changed to 2.5.0. The change to
1228 keep it programmatically in sync with the Python version running
1229 the code (introduced in 2.5b3) has been reverted. It will continue
1230 to be maintained manually as static string literal.
1231
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001232- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001233 and this cannot be converted to the required C type, an exception is
1234 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001235 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001236
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001237- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001238 an exception.
1239
Tim Peterscbdd3502006-09-05 01:47:53 +00001240- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001241 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001242 workarounds for clocks with low resolution, to stop the code yielding
1243 duplicate UUIDs.
1244
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001245- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1246 before raising SystemExit, allowing IDLE to honor quit() and exit().
1247
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001248- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1249
Georg Brandl7a1af772006-08-14 21:55:28 +00001250- Patch #1536071: trace.py should now find the full module name of a
1251 file correctly even on Windows.
1252
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001253- logging's atexit hook now runs even if the rest of the module has
1254 already been cleaned up.
1255
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001256- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001257
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001258- Bug #1531405, format_exception no longer raises an exception if
1259 str(exception) raised an exception.
1260
Neil Schemenauer06ded092006-08-04 16:20:30 +00001261- Fix a bug in the ``compiler`` package that caused invalid code to be
1262 generated for nested functions.
1263
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001264
1265Extension Modules
1266-----------------

1271
Georg Brandl3335a7a2006-08-14 21:42:55 +00001272- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1273 raises the correct exceptions.
1274
Thomas Heller1ce433e2006-08-14 16:20:04 +00001275- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1276 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1277
Thomas Heller86720042006-08-14 11:17:48 +00001278- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1279 uses the _as_parameter_ attribute when objects are passed to foreign
1280 function calls. The ctypes version number was changed to 1.0.1.
1281
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001282- Bug #1530559, struct.pack raises TypeError where it used to convert.
1283 Passing float arguments to struct.pack when integers are expected
1284 now triggers a DeprecationWarning.
1285
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001286
1287Tests

1308-----
1309
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001310- Bug #1535502, build _hashlib on Windows, and use masm assembler
1311 code in OpenSSL.
1312
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001313- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.
1314
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001315- Bug #1530448, ctypes build failure on Solaris 10 was fixed.
Thomas Heller17984892006-08-04 18:57:34 +00001316
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001317
Tim Peters4643c2f2006-08-10 22:45:34 +00001318C API
1319-----
1320
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001321- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1322
Tim Peters4643c2f2006-08-10 22:45:34 +00001323- Bug #1069160. Internal correctness changes were made to
1324 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1325 the documentation was changed to state that the return value
1326 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001329What's New in Python 2.5 beta 3?
1330================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001331
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001332*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001333
1334Core and builtins
1335-----------------
1336
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001337- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001338 returned a long (see PEP 353).
1339
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001340- Bug #1515471: string.replace() accepts character buffers again.
1341
Neal Norwitz07aadb12006-07-30 06:55:48 +00001342- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1343 This provides the proper warning for struct.pack().
1344 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1345
Neal Norwitz0d62a062006-07-30 06:53:31 +00001346- Patch #1531113: Fix augmented assignment with yield expressions.
1347 Also fix a SystemError when trying to assign to yield expressions.
1348
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001349- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1350 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1351 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1352 excessive filesystem operations during imports.
1353
Tim Petersbc24eee2006-07-27 01:14:53 +00001354- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1355 operations on signed longs that are formally undefined by C.
1356 Unfortunately, at least one compiler now cares about that, so complicated
1357 the code to make that compiler happy again.
1358
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001359- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1360
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001361- Patch #1232023: Stop including current directory in search
1362 path on Windows.
1363
Neal Norwitze1fdb322006-07-21 05:32:28 +00001364- Fix some potential crashes found with failmalloc.
1365
Neal Norwitze7563102006-07-17 01:00:16 +00001366- Fix warnings reported by Klocwork's static analysis tool.
1367
Neal Norwitz84be93b2006-07-16 01:50:38 +00001368- Bug #1512814, Fix incorrect lineno's when code within a function
1369 had more than 255 blank lines.
1370
Georg Brandl9dceedb2006-07-12 15:31:17 +00001371- Patch #1521179: Python now accepts the standard options ``--help`` and
1372 ``--version`` as well as ``/?`` on Windows.
1373
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001374- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001375 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001376 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001377
Tim Peters112aad32006-07-19 00:03:19 +00001378- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001379 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001380 new ``sys._current_frames()`` returns a dictionary with one entry,
1381 mapping the faux "thread id" 0 to the current frame.
1382
Ronald Oussoren3075e162006-07-25 20:28:55 +00001383- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001384
Ronald Oussoren3075e162006-07-25 20:28:55 +00001385
Neal Norwitza1f10902006-07-12 07:28:29 +00001386Library
1387-------
1388
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001389- Correction of patch #1455898: In the mbcs decoder, set final=False
1390 for stream decoder, but final=True for the decode function.
1391
Georg Brandl07fec3a2006-08-01 18:49:24 +00001392- os.urandom no longer masks unrelated exceptions like SystemExit or
1393 KeyboardInterrupt.
1394
Tim Peters4643c2f2006-08-10 22:45:34 +00001395- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001396 shutil.copytree on Windows
1397
Georg Brandle34ac7c2006-07-30 11:07:23 +00001398- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1399 refers to file descriptors, not file objects.
1400
Tim Peterscbdd3502006-09-05 01:47:53 +00001401- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001402 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001403 #1513611, and probably others.
1404
Georg Brandledd9b0d2006-07-29 09:33:26 +00001405- Bug #1441397: The compiler module now recognizes module and function
1406 docstrings correctly as it did in Python 2.4.
1407
Tim Peters6f681472006-07-27 23:44:37 +00001408- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1409 lost that tests are sorted by name before being run. This rarely
1410 matters for well-written tests, but can create baffling symptoms if
1411 side effects from one test to the next affect outcomes. ``DocTestFinder``
1412 has been changed to sort the list of tests it returns.
1413
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001414- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001415 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001416
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001417- Bug #978833: Really close underlying socket in _socketobject.close.
1418
Georg Brandldb232dc2006-08-20 13:15:43 +00001419- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1420 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001421
Georg Brandlcf0c1722006-07-26 07:23:32 +00001422- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1423 to recursive calls and call it with the failing package name.
1424
Martin v. Löwis0b483032006-07-25 09:53:12 +00001425- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1426
Georg Brandlc13c34c2006-07-24 14:09:56 +00001427- Patch #1515343: Fix printing of deprecated string exceptions with a
1428 value in the traceback module.
1429
Greg Ward48fae7a2006-07-23 16:05:51 +00001430- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1431
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001432- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1433
Brett Cannoncaebe222006-07-18 04:41:36 +00001434- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1435 argument tuple. For arguments where zero is illegal, the value is forced to
1436 the minimum value that is correct. This is to support an undocumented but
1437 common way people used to fill in inconsequential information in the time
1438 tuple pre-2.4.
1439
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001440- Patch #1220874: Update the binhex module for Mach-O.
1441
Barry Warsawb110bad2006-07-21 14:51:07 +00001442- The email package has improved RFC 2231 support, specifically for
1443 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1444 (name*0=<blah>) parameter continuations. This may change the types of
1445 values returned from email.message.Message.get_param() and friends.
1446 Specifically in some cases where non-encoded continuations were used,
1447 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1448 will just return the string (since non-encoded continuations don't have
1449 charset and language parts).
1450
1451 Also, whereas % values were decoded in all parameter continuations, they are
1452 now only decoded in encoded parameter parts.
1453
Ronald Oussoren3075e162006-07-25 20:28:55 +00001454- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1455
1456- Bug #1517996: IDLE now longer shows the default Tk menu when a
1457 path browser, class browser or debugger is the frontmost window on MacOS X
1458
Barry Warsaw00decd72006-07-27 23:43:15 +00001459- Patch #1520294: Support for getset and member descriptors in types.py,
1460 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1461 of an object against these built-in types and more importantly, for getting
1462 their docstrings printed in the interactive interpreter's help() function.

1466-----------------
1467
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001468- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1469 a socket operation on a socket with a timeout, the exception will be
1470 caught correctly. Previously, the exception was not caught.
1471
Thomas Heller1393d6a2006-07-28 21:43:20 +00001472- Patch #1529514: The _ctypes extension is now compiled on more
1473 openbsd target platforms.
1474
Tim Peters9cab5932006-07-28 00:30:00 +00001475- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1476 a memory leak, affecting pickles and deep copies.
1477
Tim Petersbc24eee2006-07-27 01:14:53 +00001478- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1482
Thomas Hellerce049a02006-07-14 17:51:14 +00001483- Patch #1521817: Index range checking on ctypes arrays containing
1484 exactly one element enabled again. This allows iterating over these
1485 arrays, without the need to check the array size before.
1486
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001487- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001488 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001489 /dev/null in certain cases; this is now fixed.
1490
Thomas Heller47d7a062006-07-12 08:43:47 +00001491- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1492 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001493
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001494- Because of a misspelled preprocessor symbol, ctypes was always
1495 compiled without thread support; this is now fixed.
1496
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001497- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1498 methods now allow their database parameter to be None as the
1499 sleepycat API allows.
1500
Matt Flemingec926502006-07-28 11:27:27 +00001501- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1502 bluetooth API compared with Linux and FreeBSD.
1503
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001504Tests
1505-----
1506
1507- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1508 how long the test file should take to play. Now accepts taking 2.93 secs
1509 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1510
Georg Brandl4793aa32006-07-28 18:31:39 +00001511- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1512 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1513 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +00001514
Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001515Build
1516-----
1517
1518- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1519
Ronald Oussoren26cad082006-08-01 21:00:57 +00001520Mac
1521---
1522
1523- PythonLauncher now works correctly when the path to the script contains
1524 characters that are treated specially by the shell (such as quotes).
1525
1526- Bug #1527397: PythonLauncher now launches scripts with the working directory
1527 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001528 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001529 expect.

1538-----------------
1539
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001540- Bug #1441486: The literal representation of -(sys.maxint - 1)
1541 again evaluates to a int object, not a long.
1542
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001543- Bug #1501934: The scope of global variables that are locally assigned
1544 using augmented assignment is now correctly determined.
1545
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001546- Bug #927248: Recursive method-wrapper objects can now safely
1547 be released.
1548
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001549- Bug #1417699: Reject locale-specific decimal point in float()
1550 and atof().
1551
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001552- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1553 omit a default "error" argument for NULL pointer. This allows
1554 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001555
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001556- Bug #1519018: 'as' is now validated properly in import statements.
1557
Neal Norwitz28746ab2006-07-09 22:14:42 +00001558- On 64 bit systems, int literals that use less than 64 bits are
1559 now ints rather than longs.
1560
Neal Norwitzed657552006-07-10 00:04:44 +00001561- Bug #1512814, Fix incorrect lineno's when code at module scope
1562 started after line 256.
1563
Tim Peters32a83612006-07-10 21:08:24 +00001564- New function ``sys._current_frames()`` returns a dict mapping thread
1565 id to topmost thread stack frame. This is for expert use, and is
1566 especially useful for debugging application deadlocks. The functionality
1567 was previously available in Fazal Majid's ``threadframe`` extension
1568 module, but it wasn't possible to do this in a wholly threadsafe way from
1569 an extension.

1578
Tim Peters32a83612006-07-10 21:08:24 +00001579- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001580 environment variable to be set in order to the SDK environment
1581 for finding the compiler, include files, etc.

1586
Thomas Woutersadd19112006-07-05 11:03:49 +00001587- string.Template() now correctly handles tuple-values. Previously,
1588 multi-value tuples would raise an exception and single-value tuples would
1589 be treated as the value they contain, instead.
1590
Martin v. Löwisede77f52006-07-03 13:01:35 +00001591- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1592 even if some data are received.
1593
Martin v. Löwis45482392006-07-03 12:28:58 +00001594- Bug #1267547: Put proper recursive setup.py call into the

1598 degrees and radians.
1599
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001600- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001601 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001602
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001603- Bug #1514703: Only setup canvas window in turtle when the canvas
1604 is created.
1605
Martin v. Löwis7596e832006-07-01 15:33:37 +00001606- Bug #1513223: .close() of a _socketobj now releases the underlying

1610 attribute values.
1611
1612- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1613 sgmllib ('[' and ']' were not accepted).
1614
Georg Brandl1be63af2006-06-28 20:23:25 +00001615- Fix a bug in the turtle module's end_fill function.
1616
Brett Cannon53ab5b72006-06-22 16:49:14 +00001617- Bug #1510580: The 'warnings' module improperly required that a Warning
1618 category be either a types.ClassType and a subclass of Warning. The proper
1619 check is just that it is a subclass with Warning as the documentation states.
1620
Georg Brandlad29e632006-06-21 17:45:17 +00001621- The compiler module now correctly compiles the new try-except-finally
1622 statement (bug #1509132).
1623
Neal Norwitz60373cd2006-06-22 06:30:50 +00001624- The wsgiref package is now installed properly on Unix.
1625

1627 shutdown when fileConfig() was called multiple times.
1628
Gerhard Häring762fbd32006-07-02 17:48:30 +00001629- The sqlite3 module did cut off data from the SQLite database at the first
1630 null character before sending it to a custom converter. This has been fixed
1631 now.
1632
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001633Extension Modules
1634-----------------
1635
Tim Peters112aad32006-07-19 00:03:19 +00001636- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1637 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1638 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001639
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001640- Assigning None to pointer type fields in ctypes structures possible
1641 overwrote the wrong fields, this is fixed now.
1642
1643- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1644 on non-Windows platforms.
1645
1646- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1647 integer or long, without range checking.
1648
1649- Patch #1517790: It is now possible to use custom objects in the ctypes
1650 foreign function argtypes sequence as long as they provide a from_param
1651 method, no longer is it required that the object is a ctypes type.
1652
1653- The '_ctypes' extension module now works when Python is configured
1654 with the --without-threads option.
1655
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001656- Bug #1513646: os.access on Windows now correctly determines write
1657 access, again.
1658
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001659- Bug #1512695: cPickle.loads could crash if it was interrupted with
1660 a KeyboardInterrupt.
1661
Neal Norwitza12aa882006-07-06 06:45:08 +00001662- Bug #1296433: parsing XML with a non-default encoding and
1663 a CharacterDataHandler could crash the interpreter in pyexpat.
1664
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001665- Patch #1516912: improve Modules support for OpenVMS.

1671
Tim Peters32a83612006-07-10 21:08:24 +00001672- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001673 Previously, the slight difference could cause compilation errors of the
1674 'zlib' module on systems with more than one version of zlib.
1675
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001676- The MSI compileall step was fixed to also support a TARGETDIR
1677 with spaces in it.

1695 documentation for the warnings module.
1696
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001697- Patch #1509163: MS Toolkit Compiler no longer available.

1708-----------------
1709
Georg Brandla56b9152006-06-19 06:35:54 +00001710- Patch #1507676: Error messages returned by invalid abstract object operations
1711 (such as iterating over an integer) have been improved and now include the
1712 type of the offending object to help with debugging.
1713
Brett Cannonea3912b2006-06-13 21:46:41 +00001714- Bug #992017: A classic class that defined a __coerce__() method that returned
1715 its arguments swapped would infinitely recurse and segfault the interpreter.
1716
Neal Norwitz909eb122006-06-12 02:13:21 +00001717- Fix the socket tests so they can be run concurrently.
1718
Neal Norwitzb9845e72006-06-12 02:11:18 +00001719- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001720 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001721
Brett Cannon22565aa2006-06-09 22:31:23 +00001722- Bug #532646: object.__call__() will continue looking for the __call__
1723 attribute on objects until one without one is found. This leads to recursion
1724 when you take a class and set its __call__ attribute to an instance of the
1725 class. Originally fixed for classic classes, but this fix is for new-style.
1726 Removes the infinite_rec_3 crasher.
1727
Georg Brandl24250812006-06-09 18:45:48 +00001728- The string and unicode methods startswith() and endswith() now accept
1729 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1730
Brett Cannonde3b0522006-06-08 17:00:45 +00001731- Buffer objects, at the C level, never used the char buffer
1732 implementation even when the char buffer for the wrapped object was
1733 explicitly requested (originally returned the read or write buffer).
1734 Now a TypeError is raised if the char buffer is not present but is
1735 requested.
1736
Georg Brandlddbaa662006-06-04 21:56:52 +00001737- Patch #1346214: Statements like "if 0: suite" are now again optimized
1738 away like they were in Python 2.4.
1739
Georg Brandlb7c8f542006-05-27 12:30:25 +00001740- Builtin exceptions are now full-blown new-style classes instead of
1741 instances pretending to be classes, which speeds up exception handling
1742 by about 80% in comparison to 2.5a2.
1743
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001744- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1745 Unicode 4.1.
1746
Georg Brandlf4ef1162006-05-26 18:03:31 +00001747- Patch #921466: sys.path_importer_cache is now used to cache valid and
1748 invalid file paths for the built-in import machinery which leads to
1749 fewer open calls on startup.
1750
Tim Peters696cf432006-05-24 21:10:40 +00001751- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1752 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1753 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1754 the number of input digits (it was and remains linear-time for bases
1755 2, 4, 8, 16 and 32).
1756
Tim Petersb713ec22006-05-23 18:45:30 +00001757- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1758 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1759 an integer close to ``sys.maxint``. This was repaired by patch
1760 #1335972, which also gives a nice speedup.
1761
Richard Jonescebbefc2006-05-23 18:28:17 +00001762- Patch #1337051: reduced size of frame objects.
1763
1764- PyErr_NewException now accepts a tuple of base classes as its
1765 "base" parameter.
1766
Richard Jones7c88dcc2006-05-23 10:37:38 +00001767- Patch #876206: function call speedup by retaining allocated frame
1768 objects.
1769
Georg Brandl7b90e162006-05-18 07:01:27 +00001770- Bug #1462152: file() now checks more thoroughly for invalid mode
1771 strings and removes a possible "U" before passing the mode to the
1772 C library function.
1773
Neal Norwitz1004a532006-05-15 07:17:23 +00001774- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1775
Neal Norwitz373f0a72006-05-15 07:04:36 +00001776- Bug #1487966: Fix SystemError with conditional expression in assignment
1777
Martin v. Löwis879768d2006-05-11 13:28:43 +00001778- WindowsError now has two error code attributes: errno, which carries
1779 the error values from errno.h, and winerror, which carries the error
1780 values from winerror.h. Previous versions put the winerror.h values
1781 (from GetLastError()) into the errno attribute.
1782
Martin v. Löwis77736712006-05-04 05:51:03 +00001783- Patch #1475845: Raise IndentationError for unexpected indent.
1784
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001785- Patch #1479181: split open() and file() from being aliases for each other.
1786
Tim Peters44bd9862006-06-01 13:49:23 +00001787- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1788 methods were always silently ignored by dictionaries when comparing keys.
1789 They are now passed through (except when using the C API function
1790 ``PyDict_GetItem()``, whose semantics did not change).
1791
1792- Bug #1456209: In some obscure cases it was possible for a class with a
1793 custom ``__eq__()`` method to confuse dict internals when class instances
1794 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1795 No, you don't have any code that did this ;-)

1798-----------------
1799
Trent Mick960a3f82006-06-28 20:30:41 +00001800- Bug #1295808: expat symbols should be namespaced in pyexpat
1801
1802- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1803
Brett Cannon6ee7d012006-06-08 16:23:04 +00001804- Change binascii.hexlify to accept a read-only buffer instead of only a char
1805 buffer and actually follow its documentation.
1806
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001807- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1808
Nick Coghlanc649ec52006-05-29 12:43:05 +00001809- Patch #1478788 (modified version): The functional extension module has
1810 been renamed to _functools and a functools Python wrapper module added.
1811 This provides a home for additional function related utilities that are
1812 not specifically about functional programming. See PEP 309.
1813
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001814- Patch #1493701: performance enhancements for struct module.
1815
Georg Brandl378d5922006-05-17 14:26:50 +00001816- Patch #1490224: time.altzone is now set correctly on Cygwin.
1817
Georg Brandl8d3342b2006-05-16 07:38:27 +00001818- Patch #1435422: zlib's compress and decompress objects now have a
1819 copy() method.
1820
Andrew MacIntyre92913322006-06-13 15:04:24 +00001821- Patch #1454481: thread stack size is now tunable at runtime for thread
1822 enabled builds on Windows and systems with Posix threads support.
1823
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001824- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1825 (up to the system limit of 32K characters).
1826
1827- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1828 As a result, these functions now raise WindowsError instead of OSError.
1829
Tim Peters7a822da2006-05-25 21:50:17 +00001830- ``time.clock()`` on Win64 should use the high-performance Windows
1831 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1832 Windows platforms).
1833
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001834- Calling Tk_Init twice is refused if the first call failed as that
1835 may deadlock.
1836
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001837- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1838 accept it without potentially using an uninitialized pointer.
1839
1840- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1841 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1842 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001843
Gregory P. Smith372b5832006-06-05 18:48:21 +00001844- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001845 [pybsddb project SF patch number 1466734]
1846
Gregory P. Smith372b5832006-06-05 18:48:21 +00001847- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1848 parameter is supplied. [SF pybsddb bug #1477863]
1849
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001850- bsddb: the __len__ method of a DB object has been fixed to return correct
1851 results. It could previously incorrectly return 0 in some cases.
1852 Fixes SF bug 1493322 (pybsddb bug 1184012).
1853
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001854- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1855 aborts the db transaction safely when a modifier callback fails.
1856 Fixes SF python patch/bug #1408584.
1857
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001858- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001859 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001860 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1861 database calls that would previously deadlock. [SF python bug #775414]
1862
Vinay Sajip28e57612006-07-01 10:45:20 +00001863- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001864
Walter Dörwald4994d952006-06-19 08:07:50 +00001865- Patch #1506645: add Python wrappers for the curses functions
1866 is_term_resized, resize_term and resizeterm.

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001871- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1872 functions.
1873
Martin v. Löwis3798da02006-06-17 18:44:27 +00001874- Patch #812986: Update turtle output even if not tracing.

Vinay Sajip28e57612006-07-01 10:45:20 +00001876- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001877 Tkinter.BaseWidget.
1878
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001879- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1880
Martin v. Löwis337487e2006-06-17 09:15:14 +00001881- Patch #763580: Add name and value arguments to Tkinter variable
1882 classes.
1883
Georg Brandl83cc0d02006-06-14 08:50:03 +00001884- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1885 mime.types file for determining MIME types.
1886
Georg Brandl2605ca82006-06-14 06:08:31 +00001887- Bug #1339007: Shelf objects now don't raise an exception in their
1888 __del__ method when initialization failed.
1889
Martin v. Löwisd8251432006-06-14 05:21:04 +00001890- Patch #1455898: The MBCS codec now supports the incremental mode for
1891 double-byte encodings.
1892
Tim Peters43898b42006-06-14 04:09:25 +00001893- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1894 guarantee that adjacent triples in the return list always describe
1895 non-adjacent blocks. Previously, a pair of matching blocks could end
1896 up being described by multiple adjacent triples that formed a partition
1897 of the matching pair.
1898
Greg Ward0e0c9f42006-06-11 16:24:11 +00001899- Bug #1498146: fix optparse to handle Unicode strings in option help,
1900 description, and epilog.
1901
Greg Wardd1c797e2006-06-11 14:42:41 +00001902- Bug #1366250: minor optparse documentation error.
1903
Greg Ward7f547402006-06-11 00:40:49 +00001904- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1905 clarify docs.
1906
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001907- The wsgiref package has been added to the standard library.
1908
Nick Coghlan676725d2006-06-08 13:54:49 +00001909- The functions update_wrapper() and wraps() have been added to the functools
1910 module. These make it easier to copy relevant metadata from the original
1911 function when writing wrapper functions.
1912
Tim Petersd6a9eef2006-06-05 01:48:21 +00001913- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1914 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001915
Martin v. Löwis3f767792006-06-04 19:36:28 +00001916- Patch #1359618: Speed up charmap encoder by using a trie structure
1917 for lookup.
1918
Tim Petersd609b1a2006-06-02 23:22:51 +00001919- The functions in the ``pprint`` module now sort dictionaries by key
1920 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1921 if and only if its display required more than one line, although that
1922 wasn't documented. The new behavior increases predictability; e.g.,
1923 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1924
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001925- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1926 (thanks for J. J. Lee).
1927
Georg Brandl2b330372006-05-28 20:23:12 +00001928- Patch #1496206: improve urllib2 handling of passwords with respect to
1929 default HTTP and HTTPS ports.
1930
George Yoshidaf3c65de2006-05-28 16:39:09 +00001931- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1932
Bob Ippolito7298f272006-05-23 18:43:47 +00001933- Patch #1281707: speed up gzip.readline.
1934
Georg Brandlb89316f2006-05-17 15:51:16 +00001935- Patch #1180296: Two new functions were added to the locale module:
1936 format_string() to get the effect of "format % items" but locale-aware,
1937 and currency() to format a monetary number with currency sign.
1938
Georg Brandle3a25832006-05-17 14:56:04 +00001939- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1940 and several features added, such as speed and geometry control.
1941
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001942- Patch #1488881: add support for external file objects in bz2 compressed
1943 tarfiles.
1944
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001945- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1946 stdout arguments, making it possible to redirect input and output
1947 for remote debugging.
1948
1949- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1950 a couple of issues, notably handling of long file names using the
1951 GNU LONGNAME extension.
1952
1953- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1954 new flag when ``name`` is already the name of an option flag.
1955
1956- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1957 package.
1958
1959- Patch #1472854: make the rlcompleter.Completer class usable on non-
1960 UNIX platforms.
1961
1962- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

2001-----------------
2002
Thomas Heller1b046642006-04-18 18:51:06 +00002003- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2004 by converting these apis from macros into exported functions again:
2005
2006 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2007 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2008 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

2011
Martin v. Löwis45294a92006-04-18 06:24:08 +00002012- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2013
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002014- All uses of PyStructSequence_InitType have been changed to initialize
2015 the type objects only once, even if the interpreter is initialized
2016 multiple times.
2017
Neal Norwitz61546162006-04-14 05:20:28 +00002018- Bug #1454485, array.array('u') could crash the interpreter. This was
2019 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2020 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2021
2022- Py_UNICODE is unsigned. It was always documented as unsigned, but
2023 due to a bug had a signed value in previous versions.
2024
Tim Peters3a5e8b12006-04-11 01:44:07 +00002025- Patch #837242: ``id()`` of any Python object always gives a positive
2026 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2027 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002028 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002029 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002030
Tim Peters3a5e8b12006-04-11 01:44:07 +00002031 def __hash__(self):
2032 return id(self) # WRONG
2033
2034 because a hash result must be a (short) Python int but it was always
2035 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002036 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002037 was always usable as a hash value before this patch. That's no longer
2038 necessarily so.
2039
2040- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002041 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002042 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002043 #1454844)
2044
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002045- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2046 involving generators that have paused outside of any ``try`` or ``with``
2047 blocks. (In 2.5a1, a paused generator that was part of a reference
2048 cycle could not be garbage collected, regardless of whether it was
2049 paused in a ``try`` or ``with`` block.)

2078 of the process using the returncode attribute, instead of
2079 abusing errno.
2080
Tim Peters711bf302006-04-25 03:31:36 +00002081- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2082 a doctest to be skipped (the code is not run, and the expected output
2083 or exception is ignored).
2084
Nick Coghlanda2268f2006-04-24 04:37:15 +00002085- Fixed contextlib.nested to cope with exceptions being raised and
2086 caught inside exit handlers.

2089 hex, octal, or binary; add ``append_const`` action; keep going if
2090 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2091 added ``epilog`` for better help generation).
2092
Tim Peters21fbd572006-04-21 21:18:10 +00002093- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2094 called from a thread spawned as a side effect of importing a module.
2095
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002096- The pydoc module now supports documenting packages contained in
2097 .zip or .egg files.
2098
2099- The pkgutil module now has several new utility functions, such
2100 as ``walk_packages()`` to support working with packages that are either
2101 in the filesystem or zip files.
2102
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002103- The mailbox module can now modify and delete messages from
2104 mailboxes, in addition to simply reading them. Thanks to Gregory
2105 K. Johnson for writing the code, and to the 2005 Google Summer of
2106 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002107

Skip Montanaro262fb922006-04-21 02:31:07 +00002131- The pstats.Stats class accepts an optional stream keyword argument to
2132 direct output to an alternate file-like object.
2133
Anthony Baxter51bcb682006-04-05 14:51:42 +00002134Build
2135-----
2136
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002137- The Makefile now has a reindent target, which runs reindent.py on
2138 the library.
2139
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002140- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002143
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002144- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2145 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002146 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002147 CXX from --with-cxx-main, see description in README.
2148
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002149- Patch #1429775: Link extension modules with the shared libpython.
2150
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002151- Fixed a libffi build problem on MIPS systems.
2152
Tim Peters8931ff12006-05-13 23:28:20 +00002153- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2154 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2155 and "%zu" for unsigned integers of type ``size_t``.
2156
Anthony Baxter51bcb682006-04-05 14:51:42 +00002157Tests
2158-----
2159
Nick Coghlanda2268f2006-04-24 04:37:15 +00002160- test_contextlib now checks contextlib.nested can cope with exceptions
2161 being raised and caught inside exit handlers.
2162
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002163- test_cmd_line now checks operation of the -m and -c command switches
2164
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002165- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2166 it separately and by hand. It also wasn't cleaning up its changes to
2167 the current Decimal context.
2168
Thomas Woutersabd08882006-04-26 15:53:30 +00002169- regrtest.py now has a -M option to run tests that test the new limits of
2170 containers, on 64-bit architectures. Running these tests is only sensible
2171 on 64-bit machines with more than two gigabytes of memory. The argument
2172 passed is the maximum amount of memory for the tests to use.

2181-------------
2182
Tim Petersb06d28c2006-05-12 01:57:59 +00002183- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2184
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002185- PEP 343: Added Context Types section to the library reference
2186 and attempted to bring other PEP 343 related documentation into
2187 line with the implementation and/or python-dev discussions.
2188
Tim Peters8dc73d22006-04-24 02:03:16 +00002189- Bug #1337990: clarified that ``doctest`` does not support examples
2190 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002193What's New in Python 2.5 alpha 1?
2194=================================
2195
Anthony Baxterebed3f62006-04-03 15:03:44 +00002196*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002197
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002198Core and builtins
2199-----------------
2200
Nick Coghlan43832302006-04-23 17:04:07 +00002201- PEP 338: -m command line switch now delegates to runpy.run_module
2202 allowing it to support modules in packages and zipfiles
2203
Martin v. Löwisc661b882006-04-20 04:54:23 +00002204- On Windows, .DLL is not an accepted file name extension for
2205 extension modules anymore; extensions are only found if they
2206 end in .PYD.
2207
Martin v. Löwisea62d252006-04-03 10:56:49 +00002208- Bug #1421664: sys.stderr.encoding is now set to the same value as
2209 sys.stdout.encoding.
2210
Neal Norwitz92e212f2006-04-03 04:48:37 +00002211- __import__ accepts keyword arguments.
2212
Georg Brandlccadf842006-03-31 18:54:53 +00002213- Patch #1460496: round() now accepts keyword arguments.
2214
Anthony Baxter262c00a2006-03-30 10:53:17 +00002215- Fixed bug #1459029 - unicode reprs were double-escaped.
2216
Hye-Shik Changd478f342006-03-23 12:32:36 +00002217- Patch #1396919: The system scope threads are reenabled on FreeBSD
2218 5.4 and later versions.
2219
Neal Norwitze98ccf62006-03-23 05:39:47 +00002220- Bug #1115379: Compiling a Unicode string with an encoding declaration
2221 now gives a SyntaxError.
2222
Georg Brandlabd1ff82006-03-18 07:59:59 +00002223- Previously, Python code had no easy way to access the contents of a
2224 cell object. Now, a ``cell_contents`` attribute has been added
2225 (closes patch #1170323).
2226
Tim Peterscf79aac2006-03-16 01:14:46 +00002227- Patch #1123430: Python's small-object allocator now returns an arena to
2228 the system ``free()`` when all memory within an arena becomes unused
2229 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2230 freed. Some applications will see a drop in virtual memory size now,
2231 especially long-running applications that, from time to time, temporarily
2232 use a large number of small objects. Note that when Python returns an
2233 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002234 platform C library will in turn return that memory to the operating system.
2235 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002236 appears to be effective at least on Microsoft C and gcc-based systems.
2237 Thanks to Evan Jones for hard work and patience.
2238
Georg Brandl533ff6f2006-03-08 18:09:27 +00002239- Patch #1434038: property() now uses the getter's docstring if there is
2240 no "doc" argument given. This makes it possible to legitimately use
2241 property() as a decorator to produce a read-only property.
2242
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002243- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2244 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2245 of requiring an int or long in slicing and a few other contexts, enabling
2246 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2247
Neal Norwitz995acdf2006-03-07 05:01:00 +00002248- Fixed various bugs reported by Coverity's Prevent tool.
2249
Brett Cannonbf364092006-03-01 04:25:17 +00002250- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2251 new exception base class, BaseException, which has a new message attribute.
2252 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2253 Raising a string exception now raises a DeprecationWarning.
2254
Thomas Woutersfb609f42006-02-28 16:37:25 +00002255- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2256 explicitly relative, using 'from .module import name' to mean 'from the same
2257 package as this module is in. Imports without dots still default to the
2258 old relative-then-absolute, unless 'from __future__ import
2259 absolute_import' is used.
2260
Brett Cannona7446e32006-02-27 23:39:10 +00002261- Properly check if 'warnings' raises an exception (usually when a filter set
2262 to "error" is triggered) when raising a warning for raising string
2263 exceptions.
2264
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002265- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002266 The name was removed from Include/code.h.
2267
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002268- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002269
Guido van Rossum1968ad32006-02-25 22:38:04 +00002270- Patch 1433928:
2271 - The copy module now "copies" function objects (as atomic objects).
2272 - dict.__getitem__ now looks for a __missing__ hook before raising
2273 KeyError.
2274
Tim Peters84ef21c2006-02-28 20:39:06 +00002275- PEP 343: with statement implemented. Needs ``from __future__ import
2276 with_statement``. Use of 'with' as a variable will generate a warning.
2277 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002278 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002279 The following objects have __context__ methods:
2280 - The built-in file type.
2281 - The thread.LockType type.
2282 - The following types defined by the threading module:
2283 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2284 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002285
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002286- Fix the encodings package codec search function to only search
2287 inside its own package. Fixes problem reported in patch #1433198.
2288
2289 Note: Codec packages should implement and register their own
2290 codec search function. PEP 100 has the details.
2291
Tim Peters9ea89d22006-06-04 03:26:02 +00002292- PEP 353: Using ``Py_ssize_t`` as the index type.
2293
2294- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2295 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2296 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2297 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2298 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002299
Neal Norwitzfc76d632006-01-10 06:03:13 +00002300- Patch #1400181, fix unicode string formatting to not use the locale.
2301 This is how string objects work. u'%f' could use , instead of .
2302 for the decimal point. Now both strings and unicode always use periods.
2303
Neal Norwitz671b9e32006-01-09 07:07:12 +00002304- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2305 configure would break checking curses.h.
2306
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002307- Bug #959576: The pwd module is now builtin. This allows Python to be
2308 built on UNIX platforms without $HOME set.
2309
Neal Norwitzc10978f2005-12-19 06:07:16 +00002310- Bug #1072182, fix some potential problems if characters are signed.
2311
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002312- Bug #889500, fix line number on SyntaxWarning for global declarations.
2313
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002314- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2315
Neal Norwitze7214a12005-12-18 05:03:17 +00002316- Support for converting hex strings to floats no longer works.
2317 This was not portable. float('0x3') now raises a ValueError.
2318
Barry Warsaw2a38a862005-12-18 01:27:35 +00002319- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002320 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002321 is now displayed in interactive prompt banner.
2322
Georg Brandlfa166682005-12-17 21:45:17 +00002323- Implementation of PEP 341 - Unification of try/except and try/finally.
2324 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002325 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002326
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002327- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2328 now encodes backslash correctly.
2329
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002330- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2331
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002332- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002333 and long longs.
2334
Neal Norwitz67715f02005-11-09 06:59:35 +00002335- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002336 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002337 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002338
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002339- Replaced most Unicode charmap codecs with new ones using the
2340 new Unicode translate string feature in the builtin charmap
2341 codec; the codecs were created from the mapping tables available
2342 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2343 encodings now include a mapping for the Apple logo)
2344
Tim Peterse3547fd2005-12-16 23:13:57 +00002345- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002346
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002347- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002348
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002349- A new AST parser implementation was completed. The abstract
2350 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002351 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002352
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002353- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002354 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2355
Neal Norwitz708e51a2005-10-03 04:48:15 +00002356- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2357
Neal Norwitz11bd1192005-10-03 00:54:56 +00002358- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2359 Provide a warning when a directory is passed on the command line.
2360
Neal Norwitz40d37812005-10-02 01:48:49 +00002361- Fix segfault with invalid coding.
2362
2363- SF bug #772896: unknown encoding results in MemoryError.
2364
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002365- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002366 supported a __len__() method which evaluated to False when the iterator
2367 was empty.
2368
Guido van Rossum630db602005-09-20 18:49:54 +00002369- On 64-bit platforms, when __len__() returns a value that cannot be
2370 represented as a C int, raise OverflowError.
2371
Skip Montanarof8948ca2005-09-19 03:54:46 +00002372- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002373 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002374
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002375- SF bug #893549: parsing keyword arguments was broken with a few format
2376 codes.
2377
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002378- Changes donated by Elemental Security to make it work on AIX 5.3
2379 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2380 bug #105470: test_pwd fails on 64bit system (Opteron).
2381
Guido van Rossum539c6622005-09-14 17:49:54 +00002382- Changes donated by Elemental Security to make it work on HP-UX 11 on
2383 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2384
Georg Brandl4550b8d2005-08-26 06:43:52 +00002385- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002386 (fixes bug #1119418).
2387
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002388- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2389
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002390- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2391 exceptions that cause a function to exit.
2392
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002393- The implementation of set() and frozenset() was revised to use its
2394 own internal data structure. Memory consumption is reduced by 1/3
2395 and there are modest speed-ups as well. The API is unchanged.
2396
Tim Petersde7990b2005-07-17 23:45:23 +00002397- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2398
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002399- SF bug #1229429: PyObject_CallMethod failed to decrement some
2400 reference counts in some error exit cases.
2401
Tim Petersecc6e6a2005-07-10 22:30:55 +00002402- SF bug #1185883: Python's small-object memory allocator took over
2403 a block managed by the platform C library whenever a realloc specified
2404 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002405 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002406 portable way to copy data from the C-managed block into Python's
2407 small-object space without risking a memory fault. Python's small-object
2408 realloc now leaves such blocks under the control of the platform C
2409 realloc.
2410
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002411- SF bug #1232517: An overflow error was not detected properly when
2412 attempting to convert a large float to an int in os.utime().
2413
Raymond Hettinger3296e692005-06-29 23:29:56 +00002414- SF bug #1224347: hex longs now print with lowercase letters just
2415 like their int counterparts.
2416
Michael W. Hudson188d4362005-06-20 16:52:57 +00002417- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2418 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2419 interpreter states; back out that fix and do a better job (see
2420 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2421 for a longer write-up of the problem).
2422
Michael W. Hudsondf888462005-06-03 14:41:55 +00002423- SF patch #1180995: marshal now uses a binary format by default when
2424 serializing floats.
2425
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002426- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2427 the routines that promise to produce IEEE 754 binary representations
2428 of floats now simply copy bytes around.
2429
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002430- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2431 278.
2432
Brett Cannonc3647ac2005-04-26 03:45:26 +00002433- patch #1109424: int, long, float, complex, and unicode now check for the
2434 proper magic slot for type conversions when subclassed. Previously the
2435 magic slot was ignored during conversion. Semantics now match the way
2436 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002437 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002438 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002439 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002440
Barry Warsawc8d907c2005-04-19 23:43:40 +00002441- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2442 NULL, now raise an AttributeError when attempting to set or delete the
2443 attribute. Previously a TypeError was raised, but this was inconsistent
2444 with the equivalent pure-Python implementation.
2445
Michael W. Hudson774479c2005-04-18 08:46:17 +00002446- It is now safe to call PyGILState_Release() before
2447 PyEval_InitThreads() (note that if there is reason to believe there
2448 are multiple threads around you still must call PyEval_InitThreads()
2449 before using the Python API; this fix is for extension modules that
2450 have no way of knowing if Python is multi-threaded yet).
2451
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002452- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2453 disabled caused a crash.
2454
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002455- Bug #1165306: instancemethod_new allowed the creation of a method
2456 with im_class == im_self == NULL, which caused a crash when called.
2457
Tim Petersecc6e6a2005-07-10 22:30:55 +00002458- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002459 fixes the crash seen in bug #1165761
2460
Raymond Hettinger96229b12005-03-11 06:49:40 +00002461- Added two new builtins, any() and all().
2462
Brett Cannon409d8f22005-03-05 06:47:57 +00002463- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002464 (e.g., ``class C(): pass`` is no longer a syntax error).
2465 Patch #1176012 added support to the 'parser' module and 'compiler' package
2466 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002467
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002468- Patch #1115086: Support PY_LONGLONG in structmember.
2469
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002470- Bug #1155938: new style classes did not check that __init__() was
2471 returning None.
2472
Tim Petersecc6e6a2005-07-10 22:30:55 +00002473- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002474 ('\') with a specific error message.
2475
Martin v. Löwisff232d72005-03-03 09:24:38 +00002476- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2477
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002478- Bug #1124295: the __name__ attribute of file objects was
2479 inadvertently made inaccessible in restricted mode.
2480
Tim Petersecc6e6a2005-07-10 22:30:55 +00002481- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002482 an ferror() call.
2483
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002484- min() and max() now support key= arguments with the same meaning as in
2485 list.sort().
2486
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002487- The peephole optimizer now performs simple constant folding in expressions:
2488 (2+3) --> (5).
2489
Raymond Hettingera422c342005-01-11 03:03:27 +00002490- set and frozenset objects can now be marshalled. SF #1098985.
2491
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002492- Bug #1077106: Poor argument checking could cause memory corruption
2493 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002494
Jeremy Hyltonab630502005-02-04 18:44:06 +00002495- The parser did not complain about future statements in illegal
2496 positions. It once again reports a syntax error if a future
2497 statement occurs after anything other than a doc string.
2498
Neil Schemenauercf52c072005-08-12 17:34:58 +00002499- Change the %s format specifier for str objects so that it returns a
2500 unicode instance if the argument is not an instance of basestring and
2501 calling __str__ on the argument returns a unicode instance.
2502
Tim Petersf4e69282006-02-27 17:15:31 +00002503- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2504 current thread state when the auto-GIL-state machinery knows about
2505 it (since the thread state is being deleted, continuing to remember it
2506 can't help, but can hurt if another thread happens to get created with
2507 the same thread id).
2508
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002509Extension Modules
2510-----------------
2511
Georg Brandl43f08a82006-03-31 18:01:16 +00002512- Patch #1380952: fix SSL objects timing out on consecutive read()s

Georg Brandlbc45a3f2006-03-17 19:17:34 +00002521
Neal Norwitz10be10c2006-03-16 06:50:13 +00002522- Everything under lib-old was removed. This includes the following modules:
2523 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002524 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002525 util, whatsound, whrandom, zmod
2526
2527- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2528
2529- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002530 is deprecated. The undocumented re.engine variable no longer exists.
2531
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002532- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2533 SS2 (single-shift 2) escape sequences correctly.
2534
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002535- The unicodedata module was updated to the 4.1 version of the Unicode
2536 database. The 3.2 version is still available as unicodedata.db_3_2_0
2537 for applications that require this specific version (such as IDNA).
2538
Neal Norwitzb62c4332006-03-04 18:35:47 +00002539- The timing module is no longer built by default. It was deprecated
2540 in PEP 4 in Python 2.0 or earlier.
2541
Guido van Rossum1968ad32006-02-25 22:38:04 +00002542- Patch 1433928: Added a new type, defaultdict, to the collections module.
2543 This uses the new __missing__ hook behavior added to dict (see above).
2544
Georg Brandldbd83392006-02-20 09:42:33 +00002545- Bug #854823: socketmodule now builds on Sun platforms even when
2546 INET_ADDRSTRLEN is not defined.
2547
Georg Brandlf4f44152006-02-18 22:29:33 +00002548- Patch #1393157: os.startfile() now has an optional argument to specify
2549 a "command verb" to invoke on the file.
2550
Neal Norwitz082b2df2006-02-07 07:04:46 +00002551- Bug #876637, prevent stack corruption when socket descriptor
2552 is larger than FD_SETSIZE.
2553
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002554- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2555 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2556 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
2557
Martin v. Löwis57a34e82006-02-04 19:12:37 +00002558- Patch #1422385: The nis module now supports access to domains other
2559 than the system default domain.
2560
Martin v. Löwis14694662006-02-03 12:54:16 +00002561- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2562 are reported, the limit on path name lengths is removed, and stat reports
2563 WindowsError now (instead of OSError).
2564
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002565- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
2566
Neal Norwitz62a21122006-01-25 05:21:55 +00002567- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
2568 before the env.

2575 Also fix ungetmouse() which did not accept arguments properly.
2576 The code now conforms to the documented signature.
2577
Neal Norwitz5e3d8622006-01-09 06:24:35 +00002578- Bug #1400115, Fix segfault when calling curses.panel.userptr()
2579 without prior setting of the userptr.
2580

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002699- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2700 been renamed to have only a single underscore prefix. This was done to
2701 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002702
Nick Coghlan43832302006-04-23 17:04:07 +00002703- PEP 338: new module runpy defines a run_module function to support
2704 executing modules which provide access to source code or a code object
2705 via the PEP 302 import mechanisms.
2706
Anthony Baxter93f5b932006-04-03 08:05:07 +00002707- The email module's parsedate_tz function now sets the daylight savings

2715 in attribute values.
2716
Anthony Baxterc51ee692006-04-01 00:57:31 +00002717- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002718 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002719 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002720 module will not be built.
2721
Tim Petersc17976e2006-04-01 00:26:53 +00002722- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2723 aren't officially supported here, and trying to use them will probably
2724 raise an exception some day. But dicts have been allowed, and "mostly
2725 worked", so support for them won't go away without warning.
2726
Georg Brandl338ef7d2006-03-31 18:42:16 +00002727- Bug #1445068: getpass.getpass() can now be given an explicit stream
2728 argument to specify where to write the prompt.
2729

Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002738- Queue.Queue objects now support .task_done() and .join() methods
2739 to make it easier to monitor when daemon threads have completed
2740 processing all enqueued tasks. Patch #1455676.
2741

2745
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002746- email 4.0 package now integrated. This is largely the same as the email 3.0
2747 package that was included in Python 2.3, except that PEP 8 module names are
2748 now used (e.g. mail.message instead of email.Message). The MIME classes
2749 have been moved to a subpackage (e.g. email.mime.text instead of
2750 email.MIMEText). The old names are still supported for now. Several
2751 deprecated Message methods have been removed and lots of bugs have been
2752 fixed. More details can be found in the email package documentation.
2753
Walter Dörwald40108c92006-03-27 08:15:44 +00002754- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2755 (a subclass of tuple) that provides incremental decoders and encoders
2756 (a way to use stateful codecs without the stream API). Python functions
2757 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2758 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2759 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002760
Walter Dörwald067db482006-03-15 22:17:27 +00002761- Patch #1359365: Calling next() on a closed StringIO.String object raises
2762 a ValueError instead of a StopIteration now (like file and cString.String do).
2763 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2764 called before (like file and StringIO.StringIO do).

Martin v. Löwis3e865952006-01-24 15:51:21 +00002814 specifications, raises IOErrors when proxies for unsupported protocols
2815 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002838 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2839 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2840 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2841 Ronald L. Rivest offered this advice for Python:
2842
2843 "The consensus of researchers in this area (at least as
2844 expressed at the NIST Hash Function Workshop 10/31/05),
2845 is that SHA-256 is a good choice for the time being, but
2846 that research should continue, and other alternatives may
2847 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002848
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002849- Added a subset of Fredrik Lundh's ElementTree package. Available

2902 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002903 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002904

2926 to W3C name (404 -> 'Not Found'). RFE #1216944.
2927
Georg Brandl9e43acf2005-07-04 17:16:07 +00002928- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2929 as this can cause problems with apps closing all file descriptors.

2942 Bug #1224621.
2943
Raymond Hettinger68c04532005-06-10 11:05:19 +00002944- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002945 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002946 the generate_tokens() function now accepts a callable argument that
2947 terminates by raising StopIteration.
2948
Georg Brandl9166e1a2005-06-04 09:20:03 +00002949- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2950
Georg Brandl268e61c2005-06-03 14:28:50 +00002951- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first

2953
Skip Montanaro174dd222005-05-14 20:54:16 +00002954- Patch #1120353: The xmlrpclib module provides better, more transparent,

2956 to True, applications shouldn't have to fiddle with the DateTime wrapper
2957 class at all.
2958
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002959- distutils.commands.upload was added to support uploading distribution
2960 files to PyPI.
2961
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002962- distutils.commands.register now encodes the data as UTF-8 before posting
2963 them to PyPI.
2964
Raymond Hettinger267b8682005-03-27 10:47:39 +00002965- decimal operator and comparison methods now return NotImplemented
2966 instead of raising a TypeError when interacting with other types. This
2967 allows other classes to implement __radd__ style methods and have them
2968 work as expected.
2969
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002970- Bug #1163325: Decimal infinities failed to hash. Attempting to
2971 hash a NaN raised an InvalidOperation instead of a TypeError.
2972
Tim Petersecc6e6a2005-07-10 22:30:55 +00002973- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002974 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2975

3007
Guido van Rossumd0641422005-02-03 15:01:24 +00003008- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3009 disables recursive traversal through instance attributes, which can
3010 be exploited in various ways.
3011
Tim Peterse3547fd2005-12-16 23:13:57 +00003012- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003013 flags on the HTTP listening socket.
3014
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003015- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3016 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3017
Fred Drakefbdeaad2006-07-29 16:56:15 +00003018- Patches #893642, #1039083: add allow_none, encoding arguments to
3019 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003020
Martin v. Löwis1d11de62005-01-29 13:29:23 +00003021- Bug #1110478: Revert os.environ.update to do putenv again.
3022
Thomas Hellerd6c6e222005-01-20 19:20:16 +00003023- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3024
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003025- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3026
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003027- Enhancements to the csv module:
3028
3029 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003030 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003031 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003032 + Dialect parameter parsing has been re-implemented to improve error
3033 reporting.
3034 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3035 dictates.
3036 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003037 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003038 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003039 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3040 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003041 + reader now allows \r characters to be quoted (previously it only allowed
3042 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003043 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003044 + Dialect classes passed to the module are no longer instantiated by
3045 the module before being parsed (the former validation scheme required
3046 this, but the mechanism was unreliable).
3047 + The dialect registry now contains instances of the internal
3048 C-coded dialect type, rather than references to python objects.
3049 + the internal c-coded dialect type is now immutable.
3050 + register_dialect now accepts the same keyword dialect specifications
3051 as the reader and writer, allowing the user to register dialects
3052 without first creating a dialect class.
3053 + a configurable limit to the size of parsed fields has been added -
3054 previously, an unmatched quote character could result in the entire
3055 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003056 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003057 the parser field size limit (returning the former limit). The initial
3058 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003059 + A line_num attribute has been added to the reader object, which tracks
3060 the number of lines read from the source iterator. This is not
3061 the same as the number of records returned, as records can span
3062 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003063 + reader and writer objects were not being registered with the cyclic-GC.
3064 This has been fixed.
3065
Brett Cannone6539c42005-01-08 02:43:53 +00003066- _DummyThread objects in the threading module now delete self.__block that is
3067 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3068 lock primitives tend to be limited in number and thus should not be wasted on
3069 a _DummyThread object. Fixes bug #1089632.
3070
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003071- The imghdr module now detects Exif files.
3072
Raymond Hettinger6065d322004-12-20 23:51:53 +00003073- StringIO.truncate() now correctly adjusts the size attribute.
3074 (Bug #951915).
3075
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003076- locale.py now uses an updated locale alias table (built using
3077 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3078 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003079 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003080
Raymond Hettinger3557f422004-12-07 12:02:02 +00003081- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3082
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003083- the pickle module no longer accepts the deprecated None option in the
3084 args tuple returned by __reduce__().
3085
Brett Cannon84667c02004-12-07 03:25:18 +00003086- optparse now optionally imports gettext. This allows its use in setup.py.
3087
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003088- the pickle module no longer uses the deprecated bin parameter.
3089
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003090- the shelve module no longer uses the deprecated binary parameter.
3091
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003092- the pstats module no longer uses the deprecated ignore() method.
3093
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003094- the filecmp module no longer uses the deprecated use_statcache argument.
3095
Raymond Hettinger664347b2004-12-04 21:21:53 +00003096- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3097 extended or overridden by subclasses. Formerly, the subclassed method would
3098 be ignored by the rest of the module. (Bug #1078905).
3099
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003100- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003101 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003102
Walter Dörwald36733692004-12-22 12:50:50 +00003103- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3104 once when a size argument is given. This prevents a buffer overflow in the
3105 tokenizer with very long source lines.
3106
Barry Warsaw538561e2006-01-01 21:48:54 +00003107- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3108 immediately after creating the object, without any intervening
3109 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003110
Skip Montanaro05885812005-01-16 20:48:27 +00003111- The reconvert.quote function can now emit triple-quoted strings. The
3112 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003113
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003114- ``UserString.MutableString`` now supports negative indices in
3115 ``__setitem__`` and ``__delitem__``
3116
Greg Ward40407942005-03-05 02:53:17 +00003117- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3118 correctly.
3119
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003120- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3121 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3122 character even if the user has passed a size parameter to get a proper
3123 line ending. Remove the special handling of a "\r\n" that has been split
3124 between two lines.
3125
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003126- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3127 about illegal code points. The codec now supports PEP 293 style error
3128 handlers.
3129
Walter Dörwald78a78b02005-09-01 12:04:29 +00003130- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003131 from the input stream, so that the output is a byte string in the correct
3132 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003133
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003134- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3135 considering it exactly like a '*'.
3136
Walter Dörwald007f8df2005-10-09 19:42:27 +00003137- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3138 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003139
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003140- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3141
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003142- Patch #1413711: Certain patterns of differences were making difflib
3143 touch the recursion limit.
3144
Walter Dörwald58917a62006-03-31 15:26:22 +00003145- Bug #947906: An object oriented interface has been added to the calendar
3146 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003147 called as a script (e.g. via ``python -mcalendar``). Localized month and
3148 weekday names can be ouput (even if an exotic encoding is used) using
3149 special classes that use unicode.

3153
Neal Norwitz602d3392006-03-31 08:21:40 +00003154- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3155 by using -mieee gcc option.
3156

3158
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003159- Build support for Win64-AMD64 was added.
3160
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003161- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3162
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003163- Patch #881820: look for openpty and forkpty also in libbsd.
3164
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003165- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3166 The zlib module is now builtin on Windows.
3167
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003168- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3169
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003170- Bug #1189330: configure did not correctly determine the necessary
3171 value of LINKCC if python was built with GCC 4.0.
3172
Trent Mick8321b422005-07-26 02:29:21 +00003173- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3174 vulnerability in zlib 1.2.1 and 1.2.2.
3175
Brett Cannon08cd5982005-04-24 22:26:38 +00003176- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3177 flags that change binary compatibility. Changes were also made to
3178 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003179 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003180
Bob Ippolitoed233462005-03-29 13:47:59 +00003181- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3182 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3183 no longer exists). This configure patch makes things right.
3184
Martin v. Löwise2713be2005-03-08 15:03:08 +00003185- Bug #1158607: Build with --disable-unicode again.
3186
Brett Cannon46d96232005-02-16 00:07:19 +00003187- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3188 defined. Discovered as a result of not being able to build on OS X.
3189
Brett Cannon516592f2004-12-07 00:42:59 +00003190- setup.py now uses the directories specified in LDFLAGS using the -L option
3191 and in CPPFLAGS using the -I option for adding library and include
3192 directories, respectively, for compiling extension modules against. This has
3193 led to the core being compiled using the values in CPPFLAGS. It also removes
3194 the need for the special-casing of both DarwinPorts and Fink for darwin since
3195 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3196 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3197 Fink, ``-I/opt/local/include`` for DarwinPorts).
3198
Brett Cannon43802422005-02-10 20:48:03 +00003199- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3200 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3201 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3202 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003204C API
3205-----
3206
Tim Petersc9d78aa2006-03-26 23:27:58 +00003207- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3208 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3209 is obtained via the ``PyObject_`` family, it must be released via the
3210 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3211 always been officially true, but when Python's small-object allocator was
3212 introduced, an attempt was made to cater to a few extension modules
3213 discovered at the time that obtained memory via ``PyObject_New`` but
3214 released it via ``PyMem_DEL``. It's years later, and if such code still
3215 exists it will fail now (probably with segfaults, but calling wrong
3216 low-level memory management functions can yield many symptoms).
3217
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003218- Added a C API for set and frozenset objects.
3219
Raymond Hettinger66517482004-12-03 11:45:13 +00003220- Removed PyRange_New().
3221
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003222- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3223 mapping argument now. This string is used as a mapping table. Byte values
3224 greater than the length of the string and 0xFFFE are treated as undefined
3225 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003232
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003233- Patch #1276356: New resource "urlfetch" is implemented. This enables
3234 even impatient people to run tests that require remote files.
