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

Amaury Forgeot d'Arc198e3532008-03-27 23:41:59 +0000101- Issue #2495: tokenize.untokenize now inserts a space between two consecutive
102 string literals; previously, ["" ""] was rendered as [""""], which is
103 incorrect python code.
104
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +0000105- Issue #2482: Make sure that the coefficient of a Decimal is always
106 stored as a str instance, not as a unicode instance. This ensures
107 that str(Decimal) is always an instance of str. This fixes a
108 regression from Python 2.5.1 to Python 2.5.2.

Gregory P. Smithb4bc9b92008-08-04 00:15:54 +0000140- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
141 argument in python 2.5, this broke code that subclassed Popen to include its
142 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000220- Issue #1920: "while 0" statements were completely removed by the compiler,
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000221 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000222 the condition is false. Now the compiler correctly emits bytecode for the

Guido van Rossumc69ac252006-08-10 18:09:25 +00001175What's New in Python 2.5 release candidate 1?
1176=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001177
Anthony Baxterb4096662006-08-16 03:42:26 +00001178*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001179
1180Core and builtins
1181-----------------
1182
Neal Norwitz24b6f202006-09-05 04:43:56 +00001183- Fix infinite recursion when subclassing long and overriding __hash__.
1184
1185- Fix concatenation (+=) of long strings.
1186
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001187- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001188 compared equal or unequal to a string and a UnicodeDecodeError
1189 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001190
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001191 Instead, the equal (==) and unequal (!=) comparison operators will
1192 now issue a UnicodeWarning and interpret the two objects as
1193 unequal. The UnicodeWarning can be filtered as desired using
1194 the warning framework, e.g. silenced completely, turned into an
1195 exception, logged, etc.
1196
1197 Note that compare operators other than equal and unequal will still
1198 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001199
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001200- Fix segfault when doing string formatting on subclasses of long.
1201
1202- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1203 with new-style classes.
1204
1205- Fix bug related to __len__ functions returning negative values with
1206 classic classes.
1207
1208- Patch #1538606, Fix __index__() clipping. There were some problems
1209 discovered with the API and how integers that didn't fit into Py_ssize_t
1210 were handled. This patch attempts to provide enough alternatives
1211 to effectively use __index__.
1212
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001213- Bug #1536021: __hash__ may now return long int; the final hash
1214 value is obtained by invoking hash on the long int.
1215
Thomas Hellerab1049c2006-08-08 17:37:00 +00001216- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1217
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001218- Bug #1535165: fixed a segfault in input() and raw_input() when
1219 sys.stdin is closed.
1220
Thomas Heller74d36f02006-08-04 18:17:40 +00001221- On Windows, the PyErr_Warn function is now exported from
1222 the Python dll again.
1223
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001224- Bug #1191458: tracing over for loops now produces a line event
1225 on each iteration. Fixing this problem required changing the .pyc
1226 magic number. This means that .pyc files generated before 2.5c1
1227 will be regenerated.
1228
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001229- Bug #1333982: string/number constants were inappropriately stored
1230 in the byte code and co_consts even if they were not used, ie
1231 immediately popped off the stack.
1232
Georg Brandle9462c72006-08-04 18:03:37 +00001233- Fixed a reference-counting problem in property().
1234
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001235
1236Library
1237-------
1238
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001239- Fix a bug in the ``compiler`` package that caused invalid code to be
1240 generated for generator expressions.
1241
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001242- The distutils version has been changed to 2.5.0. The change to
1243 keep it programmatically in sync with the Python version running
1244 the code (introduced in 2.5b3) has been reverted. It will continue
1245 to be maintained manually as static string literal.
1246
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001247- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001248 and this cannot be converted to the required C type, an exception is
1249 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001250 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001251
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001252- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001253 an exception.
1254
Tim Peterscbdd3502006-09-05 01:47:53 +00001255- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001256 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001257 workarounds for clocks with low resolution, to stop the code yielding
1258 duplicate UUIDs.
1259
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001260- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1261 before raising SystemExit, allowing IDLE to honor quit() and exit().
1262
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001263- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1264
Georg Brandl7a1af772006-08-14 21:55:28 +00001265- Patch #1536071: trace.py should now find the full module name of a
1266 file correctly even on Windows.
1267
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001268- logging's atexit hook now runs even if the rest of the module has
1269 already been cleaned up.
1270
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001271- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001272
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001273- Bug #1531405, format_exception no longer raises an exception if
1274 str(exception) raised an exception.
1275
Neil Schemenauer06ded092006-08-04 16:20:30 +00001276- Fix a bug in the ``compiler`` package that caused invalid code to be
1277 generated for nested functions.
1278
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001279
1280Extension Modules

1286
Georg Brandl3335a7a2006-08-14 21:42:55 +00001287- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1288 raises the correct exceptions.
1289
Thomas Heller1ce433e2006-08-14 16:20:04 +00001290- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1291 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1292
Thomas Heller86720042006-08-14 11:17:48 +00001293- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1294 uses the _as_parameter_ attribute when objects are passed to foreign
1295 function calls. The ctypes version number was changed to 1.0.1.
1296
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001297- Bug #1530559, struct.pack raises TypeError where it used to convert.
1298 Passing float arguments to struct.pack when integers are expected
1299 now triggers a DeprecationWarning.
1300

1324
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001325- Bug #1535502, build _hashlib on Windows, and use masm assembler
1326 code in OpenSSL.
1327
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001328- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.
1329
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001330- Bug #1530448, ctypes build failure on Solaris 10 was fixed.
Thomas Heller17984892006-08-04 18:57:34 +00001331
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001332
Tim Peters4643c2f2006-08-10 22:45:34 +00001333C API
1334-----
1335
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001336- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1337
Tim Peters4643c2f2006-08-10 22:45:34 +00001338- Bug #1069160. Internal correctness changes were made to
1339 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1340 the documentation was changed to state that the return value
1341 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001344What's New in Python 2.5 beta 3?
1345================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001346
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001347*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001348
1349Core and builtins
1350-----------------
1351
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001352- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001353 returned a long (see PEP 353).
1354
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001355- Bug #1515471: string.replace() accepts character buffers again.
1356
Neal Norwitz07aadb12006-07-30 06:55:48 +00001357- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1358 This provides the proper warning for struct.pack().
1359 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1360
Neal Norwitz0d62a062006-07-30 06:53:31 +00001361- Patch #1531113: Fix augmented assignment with yield expressions.
1362 Also fix a SystemError when trying to assign to yield expressions.
1363
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001364- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1365 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1366 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1367 excessive filesystem operations during imports.
1368
Tim Petersbc24eee2006-07-27 01:14:53 +00001369- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1370 operations on signed longs that are formally undefined by C.
1371 Unfortunately, at least one compiler now cares about that, so complicated
1372 the code to make that compiler happy again.
1373
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001374- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1375
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001376- Patch #1232023: Stop including current directory in search
1377 path on Windows.
1378
Neal Norwitze1fdb322006-07-21 05:32:28 +00001379- Fix some potential crashes found with failmalloc.
1380
Neal Norwitze7563102006-07-17 01:00:16 +00001381- Fix warnings reported by Klocwork's static analysis tool.
1382
Neal Norwitz84be93b2006-07-16 01:50:38 +00001383- Bug #1512814, Fix incorrect lineno's when code within a function
1384 had more than 255 blank lines.
1385
Georg Brandl9dceedb2006-07-12 15:31:17 +00001386- Patch #1521179: Python now accepts the standard options ``--help`` and
1387 ``--version`` as well as ``/?`` on Windows.
1388
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001389- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001390 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001391 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001392
Tim Peters112aad32006-07-19 00:03:19 +00001393- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001394 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001395 new ``sys._current_frames()`` returns a dictionary with one entry,
1396 mapping the faux "thread id" 0 to the current frame.
1397
Ronald Oussoren3075e162006-07-25 20:28:55 +00001398- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001399
Ronald Oussoren3075e162006-07-25 20:28:55 +00001400
Neal Norwitza1f10902006-07-12 07:28:29 +00001401Library
1402-------
1403
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001404- Correction of patch #1455898: In the mbcs decoder, set final=False
1405 for stream decoder, but final=True for the decode function.
1406
Georg Brandl07fec3a2006-08-01 18:49:24 +00001407- os.urandom no longer masks unrelated exceptions like SystemExit or
1408 KeyboardInterrupt.
1409
Tim Peters4643c2f2006-08-10 22:45:34 +00001410- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001411 shutil.copytree on Windows
1412
Georg Brandle34ac7c2006-07-30 11:07:23 +00001413- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1414 refers to file descriptors, not file objects.
1415
Tim Peterscbdd3502006-09-05 01:47:53 +00001416- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001417 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001418 #1513611, and probably others.
1419
Georg Brandledd9b0d2006-07-29 09:33:26 +00001420- Bug #1441397: The compiler module now recognizes module and function
1421 docstrings correctly as it did in Python 2.4.
1422
Tim Peters6f681472006-07-27 23:44:37 +00001423- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1424 lost that tests are sorted by name before being run. This rarely
1425 matters for well-written tests, but can create baffling symptoms if
1426 side effects from one test to the next affect outcomes. ``DocTestFinder``
1427 has been changed to sort the list of tests it returns.
1428
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001429- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001430 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001431
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001432- Bug #978833: Really close underlying socket in _socketobject.close.
1433
Georg Brandldb232dc2006-08-20 13:15:43 +00001434- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1435 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001436
Georg Brandlcf0c1722006-07-26 07:23:32 +00001437- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1438 to recursive calls and call it with the failing package name.
1439
Martin v. Löwis0b483032006-07-25 09:53:12 +00001440- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1441
Georg Brandlc13c34c2006-07-24 14:09:56 +00001442- Patch #1515343: Fix printing of deprecated string exceptions with a
1443 value in the traceback module.
1444
Greg Ward48fae7a2006-07-23 16:05:51 +00001445- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1446
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001447- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1448
Brett Cannoncaebe222006-07-18 04:41:36 +00001449- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1450 argument tuple. For arguments where zero is illegal, the value is forced to
1451 the minimum value that is correct. This is to support an undocumented but
1452 common way people used to fill in inconsequential information in the time
1453 tuple pre-2.4.
1454
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001455- Patch #1220874: Update the binhex module for Mach-O.
1456
Barry Warsawb110bad2006-07-21 14:51:07 +00001457- The email package has improved RFC 2231 support, specifically for
1458 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1459 (name*0=<blah>) parameter continuations. This may change the types of
1460 values returned from email.message.Message.get_param() and friends.
1461 Specifically in some cases where non-encoded continuations were used,
1462 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1463 will just return the string (since non-encoded continuations don't have
1464 charset and language parts).
1465
1466 Also, whereas % values were decoded in all parameter continuations, they are
1467 now only decoded in encoded parameter parts.
1468
Ronald Oussoren3075e162006-07-25 20:28:55 +00001469- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1470
1471- Bug #1517996: IDLE now longer shows the default Tk menu when a
1472 path browser, class browser or debugger is the frontmost window on MacOS X
1473
Barry Warsaw00decd72006-07-27 23:43:15 +00001474- Patch #1520294: Support for getset and member descriptors in types.py,
1475 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1476 of an object against these built-in types and more importantly, for getting
1477 their docstrings printed in the interactive interpreter's help() function.

1481-----------------
1482
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001483- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1484 a socket operation on a socket with a timeout, the exception will be
1485 caught correctly. Previously, the exception was not caught.
1486
Thomas Heller1393d6a2006-07-28 21:43:20 +00001487- Patch #1529514: The _ctypes extension is now compiled on more
1488 openbsd target platforms.
1489
Tim Peters9cab5932006-07-28 00:30:00 +00001490- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1491 a memory leak, affecting pickles and deep copies.
1492
Tim Petersbc24eee2006-07-27 01:14:53 +00001493- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1497
Thomas Hellerce049a02006-07-14 17:51:14 +00001498- Patch #1521817: Index range checking on ctypes arrays containing
1499 exactly one element enabled again. This allows iterating over these
1500 arrays, without the need to check the array size before.
1501
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001502- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001503 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001504 /dev/null in certain cases; this is now fixed.
1505
Thomas Heller47d7a062006-07-12 08:43:47 +00001506- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1507 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001508
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001509- Because of a misspelled preprocessor symbol, ctypes was always
1510 compiled without thread support; this is now fixed.
1511
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001512- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1513 methods now allow their database parameter to be None as the
1514 sleepycat API allows.
1515
Matt Flemingec926502006-07-28 11:27:27 +00001516- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1517 bluetooth API compared with Linux and FreeBSD.
1518
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001519Tests
1520-----
1521
1522- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1523 how long the test file should take to play. Now accepts taking 2.93 secs
1524 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1525
Georg Brandl4793aa32006-07-28 18:31:39 +00001526- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1527 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1528 run via ``regrtest.py``. Now they do.

1532
1533- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1534
Ronald Oussoren26cad082006-08-01 21:00:57 +00001535Mac
1536---
1537
1538- PythonLauncher now works correctly when the path to the script contains
1539 characters that are treated specially by the shell (such as quotes).
1540
1541- Bug #1527397: PythonLauncher now launches scripts with the working directory
1542 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001543 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001544 expect.

1553-----------------
1554
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001555- Bug #1441486: The literal representation of -(sys.maxint - 1)
1556 again evaluates to a int object, not a long.
1557
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001558- Bug #1501934: The scope of global variables that are locally assigned
1559 using augmented assignment is now correctly determined.
1560
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001561- Bug #927248: Recursive method-wrapper objects can now safely
1562 be released.
1563
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001564- Bug #1417699: Reject locale-specific decimal point in float()
1565 and atof().
1566
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001567- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1568 omit a default "error" argument for NULL pointer. This allows
1569 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001570
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001571- Bug #1519018: 'as' is now validated properly in import statements.
1572
Neal Norwitz28746ab2006-07-09 22:14:42 +00001573- On 64 bit systems, int literals that use less than 64 bits are
1574 now ints rather than longs.
1575
Neal Norwitzed657552006-07-10 00:04:44 +00001576- Bug #1512814, Fix incorrect lineno's when code at module scope
1577 started after line 256.
1578
Tim Peters32a83612006-07-10 21:08:24 +00001579- New function ``sys._current_frames()`` returns a dict mapping thread
1580 id to topmost thread stack frame. This is for expert use, and is
1581 especially useful for debugging application deadlocks. The functionality
1582 was previously available in Fazal Majid's ``threadframe`` extension
1583 module, but it wasn't possible to do this in a wholly threadsafe way from
1584 an extension.
1585

1601
Thomas Woutersadd19112006-07-05 11:03:49 +00001602- string.Template() now correctly handles tuple-values. Previously,
1603 multi-value tuples would raise an exception and single-value tuples would
1604 be treated as the value they contain, instead.
1605
Martin v. Löwisede77f52006-07-03 13:01:35 +00001606- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1613 degrees and radians.
1614
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001615- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001616 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001617

1619 is created.
1620
Martin v. Löwis7596e832006-07-01 15:33:37 +00001621- Bug #1513223: .close() of a _socketobj now releases the underlying
1622 socket again, which then gets closed as it becomes unreferenced.

1627- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1628 sgmllib ('[' and ']' were not accepted).
1629
Georg Brandl1be63af2006-06-28 20:23:25 +00001630- Fix a bug in the turtle module's end_fill function.
1631
Brett Cannon53ab5b72006-06-22 16:49:14 +00001632- Bug #1510580: The 'warnings' module improperly required that a Warning
1633 category be either a types.ClassType and a subclass of Warning. The proper
1634 check is just that it is a subclass with Warning as the documentation states.
1635
Georg Brandlad29e632006-06-21 17:45:17 +00001636- The compiler module now correctly compiles the new try-except-finally
1637 statement (bug #1509132).
1638
Neal Norwitz60373cd2006-06-22 06:30:50 +00001639- The wsgiref package is now installed properly on Unix.
1640

1642 shutdown when fileConfig() was called multiple times.
1643
Gerhard Häring762fbd32006-07-02 17:48:30 +00001644- The sqlite3 module did cut off data from the SQLite database at the first
1645 null character before sending it to a custom converter. This has been fixed
1646 now.
1647
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001648Extension Modules
1649-----------------
1650
Tim Peters112aad32006-07-19 00:03:19 +00001651- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1652 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1653 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001654
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001655- Assigning None to pointer type fields in ctypes structures possible
1656 overwrote the wrong fields, this is fixed now.
1657
1658- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1659 on non-Windows platforms.
1660
1661- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1662 integer or long, without range checking.
1663
1664- Patch #1517790: It is now possible to use custom objects in the ctypes
1665 foreign function argtypes sequence as long as they provide a from_param
1666 method, no longer is it required that the object is a ctypes type.
1667
1668- The '_ctypes' extension module now works when Python is configured
1669 with the --without-threads option.
1670
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001671- Bug #1513646: os.access on Windows now correctly determines write

1686
Tim Peters32a83612006-07-10 21:08:24 +00001687- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001688 Previously, the slight difference could cause compilation errors of the
1689 'zlib' module on systems with more than one version of zlib.
1690
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001691- The MSI compileall step was fixed to also support a TARGETDIR

1728
Brett Cannonea3912b2006-06-13 21:46:41 +00001729- Bug #992017: A classic class that defined a __coerce__() method that returned
1730 its arguments swapped would infinitely recurse and segfault the interpreter.
1731
Neal Norwitz909eb122006-06-12 02:13:21 +00001732- Fix the socket tests so they can be run concurrently.

Brett Cannon22565aa2006-06-09 22:31:23 +00001737- Bug #532646: object.__call__() will continue looking for the __call__
1738 attribute on objects until one without one is found. This leads to recursion
1739 when you take a class and set its __call__ attribute to an instance of the
1740 class. Originally fixed for classic classes, but this fix is for new-style.
1741 Removes the infinite_rec_3 crasher.
1742
Georg Brandl24250812006-06-09 18:45:48 +00001743- The string and unicode methods startswith() and endswith() now accept
1744 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1745
Brett Cannonde3b0522006-06-08 17:00:45 +00001746- Buffer objects, at the C level, never used the char buffer
1747 implementation even when the char buffer for the wrapped object was
1748 explicitly requested (originally returned the read or write buffer).
1749 Now a TypeError is raised if the char buffer is not present but is
1750 requested.
1751
Georg Brandlddbaa662006-06-04 21:56:52 +00001752- Patch #1346214: Statements like "if 0: suite" are now again optimized
1753 away like they were in Python 2.4.
1754
Georg Brandlb7c8f542006-05-27 12:30:25 +00001755- Builtin exceptions are now full-blown new-style classes instead of
1756 instances pretending to be classes, which speeds up exception handling
1757 by about 80% in comparison to 2.5a2.
1758
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001759- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1760 Unicode 4.1.
1761
Georg Brandlf4ef1162006-05-26 18:03:31 +00001762- Patch #921466: sys.path_importer_cache is now used to cache valid and
1763 invalid file paths for the built-in import machinery which leads to
1764 fewer open calls on startup.
1765
Tim Peters696cf432006-05-24 21:10:40 +00001766- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1767 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1768 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1769 the number of input digits (it was and remains linear-time for bases
1770 2, 4, 8, 16 and 32).
1771
Tim Petersb713ec22006-05-23 18:45:30 +00001772- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1773 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1774 an integer close to ``sys.maxint``. This was repaired by patch
1775 #1335972, which also gives a nice speedup.
1776
Richard Jonescebbefc2006-05-23 18:28:17 +00001777- Patch #1337051: reduced size of frame objects.
1778
1779- PyErr_NewException now accepts a tuple of base classes as its
1780 "base" parameter.
1781
Richard Jones7c88dcc2006-05-23 10:37:38 +00001782- Patch #876206: function call speedup by retaining allocated frame
1783 objects.
1784
Georg Brandl7b90e162006-05-18 07:01:27 +00001785- Bug #1462152: file() now checks more thoroughly for invalid mode
1786 strings and removes a possible "U" before passing the mode to the
1787 C library function.
1788
Neal Norwitz1004a532006-05-15 07:17:23 +00001789- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1790
Neal Norwitz373f0a72006-05-15 07:04:36 +00001791- Bug #1487966: Fix SystemError with conditional expression in assignment
1792
Martin v. Löwis879768d2006-05-11 13:28:43 +00001793- WindowsError now has two error code attributes: errno, which carries
1794 the error values from errno.h, and winerror, which carries the error
1795 values from winerror.h. Previous versions put the winerror.h values
1796 (from GetLastError()) into the errno attribute.
1797
Martin v. Löwis77736712006-05-04 05:51:03 +00001798- Patch #1475845: Raise IndentationError for unexpected indent.
1799
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001800- Patch #1479181: split open() and file() from being aliases for each other.
1801
Tim Peters44bd9862006-06-01 13:49:23 +00001802- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1803 methods were always silently ignored by dictionaries when comparing keys.
1804 They are now passed through (except when using the C API function
1805 ``PyDict_GetItem()``, whose semantics did not change).
1806
1807- Bug #1456209: In some obscure cases it was possible for a class with a
1808 custom ``__eq__()`` method to confuse dict internals when class instances
1809 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1810 No, you don't have any code that did this ;-)

1813-----------------
1814
Trent Mick960a3f82006-06-28 20:30:41 +00001815- Bug #1295808: expat symbols should be namespaced in pyexpat
1816
1817- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1818
Brett Cannon6ee7d012006-06-08 16:23:04 +00001819- Change binascii.hexlify to accept a read-only buffer instead of only a char
1820 buffer and actually follow its documentation.
1821
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001822- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1823
Nick Coghlanc649ec52006-05-29 12:43:05 +00001824- Patch #1478788 (modified version): The functional extension module has
1825 been renamed to _functools and a functools Python wrapper module added.
1826 This provides a home for additional function related utilities that are
1827 not specifically about functional programming. See PEP 309.
1828
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001829- Patch #1493701: performance enhancements for struct module.
1830
Georg Brandl378d5922006-05-17 14:26:50 +00001831- Patch #1490224: time.altzone is now set correctly on Cygwin.
1832
Georg Brandl8d3342b2006-05-16 07:38:27 +00001833- Patch #1435422: zlib's compress and decompress objects now have a
1834 copy() method.
1835
Andrew MacIntyre92913322006-06-13 15:04:24 +00001836- Patch #1454481: thread stack size is now tunable at runtime for thread
1837 enabled builds on Windows and systems with Posix threads support.
1838
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001839- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1840 (up to the system limit of 32K characters).
1841
1842- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1843 As a result, these functions now raise WindowsError instead of OSError.
1844
Tim Peters7a822da2006-05-25 21:50:17 +00001845- ``time.clock()`` on Win64 should use the high-performance Windows
1846 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1847 Windows platforms).
1848
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001849- Calling Tk_Init twice is refused if the first call failed as that
1850 may deadlock.
1851
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001852- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1853 accept it without potentially using an uninitialized pointer.
1854
1855- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1856 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1857 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001858
Gregory P. Smith372b5832006-06-05 18:48:21 +00001859- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001860 [pybsddb project SF patch number 1466734]
1861
Gregory P. Smith372b5832006-06-05 18:48:21 +00001862- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1863 parameter is supplied. [SF pybsddb bug #1477863]
1864
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001865- bsddb: the __len__ method of a DB object has been fixed to return correct
1866 results. It could previously incorrectly return 0 in some cases.
1867 Fixes SF bug 1493322 (pybsddb bug 1184012).
1868
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001869- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1870 aborts the db transaction safely when a modifier callback fails.
1871 Fixes SF python patch/bug #1408584.
1872
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001873- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001874 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001875 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1876 database calls that would previously deadlock. [SF python bug #775414]
1877
Vinay Sajip28e57612006-07-01 10:45:20 +00001878- Patch #1446489: add support for the ZIP64 extensions to zipfile.

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001886- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1887 functions.
1888
Martin v. Löwis3798da02006-06-17 18:44:27 +00001889- Patch #812986: Update turtle output even if not tracing.

Vinay Sajip28e57612006-07-01 10:45:20 +00001891- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001892 Tkinter.BaseWidget.
1893
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001894- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1895
Martin v. Löwis337487e2006-06-17 09:15:14 +00001896- Patch #763580: Add name and value arguments to Tkinter variable
1897 classes.
1898
Georg Brandl83cc0d02006-06-14 08:50:03 +00001899- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1900 mime.types file for determining MIME types.
1901
Georg Brandl2605ca82006-06-14 06:08:31 +00001902- Bug #1339007: Shelf objects now don't raise an exception in their
1903 __del__ method when initialization failed.
1904
Martin v. Löwisd8251432006-06-14 05:21:04 +00001905- Patch #1455898: The MBCS codec now supports the incremental mode for
1906 double-byte encodings.
1907
Tim Peters43898b42006-06-14 04:09:25 +00001908- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1909 guarantee that adjacent triples in the return list always describe
1910 non-adjacent blocks. Previously, a pair of matching blocks could end
1911 up being described by multiple adjacent triples that formed a partition
1912 of the matching pair.
1913
Greg Ward0e0c9f42006-06-11 16:24:11 +00001914- Bug #1498146: fix optparse to handle Unicode strings in option help,
1915 description, and epilog.
1916
Greg Wardd1c797e2006-06-11 14:42:41 +00001917- Bug #1366250: minor optparse documentation error.
1918
Greg Ward7f547402006-06-11 00:40:49 +00001919- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1920 clarify docs.
1921
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001922- The wsgiref package has been added to the standard library.
1923
Nick Coghlan676725d2006-06-08 13:54:49 +00001924- The functions update_wrapper() and wraps() have been added to the functools
1925 module. These make it easier to copy relevant metadata from the original
1926 function when writing wrapper functions.
1927
Tim Petersd6a9eef2006-06-05 01:48:21 +00001928- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1929 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001930
Martin v. Löwis3f767792006-06-04 19:36:28 +00001931- Patch #1359618: Speed up charmap encoder by using a trie structure
1932 for lookup.
1933
Tim Petersd609b1a2006-06-02 23:22:51 +00001934- The functions in the ``pprint`` module now sort dictionaries by key
1935 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1936 if and only if its display required more than one line, although that
1937 wasn't documented. The new behavior increases predictability; e.g.,
1938 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1939
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001940- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1941 (thanks for J. J. Lee).
1942
Georg Brandl2b330372006-05-28 20:23:12 +00001943- Patch #1496206: improve urllib2 handling of passwords with respect to
1944 default HTTP and HTTPS ports.
1945
George Yoshidaf3c65de2006-05-28 16:39:09 +00001946- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1947
Bob Ippolito7298f272006-05-23 18:43:47 +00001948- Patch #1281707: speed up gzip.readline.
1949
Georg Brandlb89316f2006-05-17 15:51:16 +00001950- Patch #1180296: Two new functions were added to the locale module:
1951 format_string() to get the effect of "format % items" but locale-aware,
1952 and currency() to format a monetary number with currency sign.
1953
Georg Brandle3a25832006-05-17 14:56:04 +00001954- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1955 and several features added, such as speed and geometry control.
1956
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001957- Patch #1488881: add support for external file objects in bz2 compressed
1958 tarfiles.
1959
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001960- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1961 stdout arguments, making it possible to redirect input and output
1962 for remote debugging.
1963
1964- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1965 a couple of issues, notably handling of long file names using the
1966 GNU LONGNAME extension.
1967
1968- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1969 new flag when ``name`` is already the name of an option flag.
1970
1971- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1972 package.
1973
1974- Patch #1472854: make the rlcompleter.Completer class usable on non-
1975 UNIX platforms.
1976
1977- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

2016-----------------
2017
Thomas Heller1b046642006-04-18 18:51:06 +00002018- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2019 by converting these apis from macros into exported functions again:
2020
2021 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2022 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2023 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2024 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2025 PyRun_String Py_CompileString
2026
Martin v. Löwis45294a92006-04-18 06:24:08 +00002027- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2028
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002029- All uses of PyStructSequence_InitType have been changed to initialize
2030 the type objects only once, even if the interpreter is initialized
2031 multiple times.
2032
Neal Norwitz61546162006-04-14 05:20:28 +00002033- Bug #1454485, array.array('u') could crash the interpreter. This was
2034 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2035 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2036
2037- Py_UNICODE is unsigned. It was always documented as unsigned, but
2038 due to a bug had a signed value in previous versions.
2039
Tim Peters3a5e8b12006-04-11 01:44:07 +00002040- Patch #837242: ``id()`` of any Python object always gives a positive
2041 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2042 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002043 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002044 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002045
Tim Peters3a5e8b12006-04-11 01:44:07 +00002046 def __hash__(self):
2047 return id(self) # WRONG
2048
2049 because a hash result must be a (short) Python int but it was always
2050 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002051 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002052 was always usable as a hash value before this patch. That's no longer
2053 necessarily so.
2054
2055- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002056 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002057 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002058 #1454844)
2059
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002060- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2061 involving generators that have paused outside of any ``try`` or ``with``
2062 blocks. (In 2.5a1, a paused generator that was part of a reference
2063 cycle could not be garbage collected, regardless of whether it was
2064 paused in a ``try`` or ``with`` block.)

2078 the cachesize parameter.
2079
2080- Bug #1149413: bsddb.*open() no longer raises an exception when using
2081 a temporary db (file=None) with the 'n' flag to truncate on open.
2082
2083- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2084 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002085
Armin Rigoa9017c32006-04-19 11:50:27 +00002086- Patch #1062014: AF_UNIX sockets under Linux have a special
2087 abstract namespace that is now fully supported.

2091
Peter Astrand7d1d4362006-07-14 14:04:45 +00002092- Bug #1223937: subprocess.CalledProcessError reports the exit status
2093 of the process using the returncode attribute, instead of
2094 abusing errno.
2095
Tim Peters711bf302006-04-25 03:31:36 +00002096- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2097 a doctest to be skipped (the code is not run, and the expected output
2098 or exception is ignored).
2099
Nick Coghlanda2268f2006-04-24 04:37:15 +00002100- Fixed contextlib.nested to cope with exceptions being raised and
2101 caught inside exit handlers.
2102
Greg Wardab05edc2006-04-23 03:47:58 +00002103- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2104 hex, octal, or binary; add ``append_const`` action; keep going if
2105 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2106 added ``epilog`` for better help generation).
2107
Tim Peters21fbd572006-04-21 21:18:10 +00002108- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2109 called from a thread spawned as a side effect of importing a module.
2110
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002111- The pydoc module now supports documenting packages contained in
2112 .zip or .egg files.
2113
2114- The pkgutil module now has several new utility functions, such
2115 as ``walk_packages()`` to support working with packages that are either
2116 in the filesystem or zip files.
2117
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002118- The mailbox module can now modify and delete messages from
2119 mailboxes, in addition to simply reading them. Thanks to Gregory
2120 K. Johnson for writing the code, and to the 2005 Google Summer of
2121 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002122

Anthony Baxtere29002c2006-04-12 12:07:31 +00002132- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2133 Windows. Bug #1469163.
2134
Phillip J. Eby47032112006-04-11 01:07:43 +00002135- The warnings, linecache, inspect, traceback, site, and doctest modules

2145
Skip Montanaro262fb922006-04-21 02:31:07 +00002146- The pstats.Stats class accepts an optional stream keyword argument to
2147 direct output to an alternate file-like object.
2148
Anthony Baxter51bcb682006-04-05 14:51:42 +00002149Build
2150-----
2151
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002152- The Makefile now has a reindent target, which runs reindent.py on
2153 the library.
2154
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002155- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002158
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002159- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2160 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002161 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002162 CXX from --with-cxx-main, see description in README.
2163
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002164- Patch #1429775: Link extension modules with the shared libpython.
2165
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002166- Fixed a libffi build problem on MIPS systems.
2167
Tim Peters8931ff12006-05-13 23:28:20 +00002168- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2169 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2170 and "%zu" for unsigned integers of type ``size_t``.
2171
Anthony Baxter51bcb682006-04-05 14:51:42 +00002172Tests
2173-----
2174
Nick Coghlanda2268f2006-04-24 04:37:15 +00002175- test_contextlib now checks contextlib.nested can cope with exceptions
2176 being raised and caught inside exit handlers.
2177
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002178- test_cmd_line now checks operation of the -m and -c command switches
2179
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002180- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2181 it separately and by hand. It also wasn't cleaning up its changes to
2182 the current Decimal context.
2183
Thomas Woutersabd08882006-04-26 15:53:30 +00002184- regrtest.py now has a -M option to run tests that test the new limits of
2185 containers, on 64-bit architectures. Running these tests is only sensible
2186 on 64-bit machines with more than two gigabytes of memory. The argument
2187 passed is the maximum amount of memory for the tests to use.

2196-------------
2197
Tim Petersb06d28c2006-05-12 01:57:59 +00002198- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2199
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002200- PEP 343: Added Context Types section to the library reference
2201 and attempted to bring other PEP 343 related documentation into
2202 line with the implementation and/or python-dev discussions.
2203
Tim Peters8dc73d22006-04-24 02:03:16 +00002204- Bug #1337990: clarified that ``doctest`` does not support examples
2205 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002208What's New in Python 2.5 alpha 1?
2209=================================
2210
Anthony Baxterebed3f62006-04-03 15:03:44 +00002211*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002212
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002213Core and builtins
2214-----------------
2215
Nick Coghlan43832302006-04-23 17:04:07 +00002216- PEP 338: -m command line switch now delegates to runpy.run_module
2217 allowing it to support modules in packages and zipfiles
2218
Martin v. Löwisc661b882006-04-20 04:54:23 +00002219- On Windows, .DLL is not an accepted file name extension for
2220 extension modules anymore; extensions are only found if they
2221 end in .PYD.
2222
Martin v. Löwisea62d252006-04-03 10:56:49 +00002223- Bug #1421664: sys.stderr.encoding is now set to the same value as
2224 sys.stdout.encoding.
2225
Neal Norwitz92e212f2006-04-03 04:48:37 +00002226- __import__ accepts keyword arguments.
2227
Georg Brandlccadf842006-03-31 18:54:53 +00002228- Patch #1460496: round() now accepts keyword arguments.
2229
Anthony Baxter262c00a2006-03-30 10:53:17 +00002230- Fixed bug #1459029 - unicode reprs were double-escaped.
2231
Hye-Shik Changd478f342006-03-23 12:32:36 +00002232- Patch #1396919: The system scope threads are reenabled on FreeBSD
2233 5.4 and later versions.
2234
Neal Norwitze98ccf62006-03-23 05:39:47 +00002235- Bug #1115379: Compiling a Unicode string with an encoding declaration
2236 now gives a SyntaxError.
2237
Georg Brandlabd1ff82006-03-18 07:59:59 +00002238- Previously, Python code had no easy way to access the contents of a
2239 cell object. Now, a ``cell_contents`` attribute has been added
2240 (closes patch #1170323).
2241
Tim Peterscf79aac2006-03-16 01:14:46 +00002242- Patch #1123430: Python's small-object allocator now returns an arena to
2243 the system ``free()`` when all memory within an arena becomes unused
2244 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2245 freed. Some applications will see a drop in virtual memory size now,
2246 especially long-running applications that, from time to time, temporarily
2247 use a large number of small objects. Note that when Python returns an
2248 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002249 platform C library will in turn return that memory to the operating system.
2250 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002251 appears to be effective at least on Microsoft C and gcc-based systems.
2252 Thanks to Evan Jones for hard work and patience.
2253
Georg Brandl533ff6f2006-03-08 18:09:27 +00002254- Patch #1434038: property() now uses the getter's docstring if there is
2255 no "doc" argument given. This makes it possible to legitimately use
2256 property() as a decorator to produce a read-only property.
2257
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002258- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2259 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2260 of requiring an int or long in slicing and a few other contexts, enabling
2261 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2262
Neal Norwitz995acdf2006-03-07 05:01:00 +00002263- Fixed various bugs reported by Coverity's Prevent tool.
2264
Brett Cannonbf364092006-03-01 04:25:17 +00002265- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2266 new exception base class, BaseException, which has a new message attribute.
2267 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2268 Raising a string exception now raises a DeprecationWarning.
2269
Thomas Woutersfb609f42006-02-28 16:37:25 +00002270- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2271 explicitly relative, using 'from .module import name' to mean 'from the same
2272 package as this module is in. Imports without dots still default to the
2273 old relative-then-absolute, unless 'from __future__ import
2274 absolute_import' is used.
2275
Brett Cannona7446e32006-02-27 23:39:10 +00002276- Properly check if 'warnings' raises an exception (usually when a filter set
2277 to "error" is triggered) when raising a warning for raising string
2278 exceptions.
2279
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002280- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002281 The name was removed from Include/code.h.
2282
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002283- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002284
Guido van Rossum1968ad32006-02-25 22:38:04 +00002285- Patch 1433928:
2286 - The copy module now "copies" function objects (as atomic objects).
2287 - dict.__getitem__ now looks for a __missing__ hook before raising
2288 KeyError.
2289
Tim Peters84ef21c2006-02-28 20:39:06 +00002290- PEP 343: with statement implemented. Needs ``from __future__ import
2291 with_statement``. Use of 'with' as a variable will generate a warning.
2292 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002293 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002294 The following objects have __context__ methods:
2295 - The built-in file type.
2296 - The thread.LockType type.
2297 - The following types defined by the threading module:
2298 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2299 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002300
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002301- Fix the encodings package codec search function to only search
2302 inside its own package. Fixes problem reported in patch #1433198.
2303
2304 Note: Codec packages should implement and register their own
2305 codec search function. PEP 100 has the details.
2306
Tim Peters9ea89d22006-06-04 03:26:02 +00002307- PEP 353: Using ``Py_ssize_t`` as the index type.
2308
2309- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2310 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2311 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2312 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2313 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002314
Neal Norwitzfc76d632006-01-10 06:03:13 +00002315- Patch #1400181, fix unicode string formatting to not use the locale.
2316 This is how string objects work. u'%f' could use , instead of .
2317 for the decimal point. Now both strings and unicode always use periods.
2318
Neal Norwitz671b9e32006-01-09 07:07:12 +00002319- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2320 configure would break checking curses.h.
2321
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002322- Bug #959576: The pwd module is now builtin. This allows Python to be
2323 built on UNIX platforms without $HOME set.
2324
Neal Norwitzc10978f2005-12-19 06:07:16 +00002325- Bug #1072182, fix some potential problems if characters are signed.
2326
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002327- Bug #889500, fix line number on SyntaxWarning for global declarations.
2328
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002329- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2330
Neal Norwitze7214a12005-12-18 05:03:17 +00002331- Support for converting hex strings to floats no longer works.
2332 This was not portable. float('0x3') now raises a ValueError.
2333
Barry Warsaw2a38a862005-12-18 01:27:35 +00002334- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002335 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002336 is now displayed in interactive prompt banner.
2337
Georg Brandlfa166682005-12-17 21:45:17 +00002338- Implementation of PEP 341 - Unification of try/except and try/finally.
2339 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002340 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002341
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002342- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2343 now encodes backslash correctly.
2344
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002345- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2346
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002347- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002348 and long longs.
2349
Neal Norwitz67715f02005-11-09 06:59:35 +00002350- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002351 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002352 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002353
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002354- Replaced most Unicode charmap codecs with new ones using the
2355 new Unicode translate string feature in the builtin charmap
2356 codec; the codecs were created from the mapping tables available
2357 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2358 encodings now include a mapping for the Apple logo)
2359
Tim Peterse3547fd2005-12-16 23:13:57 +00002360- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002361
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002362- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002363
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002364- A new AST parser implementation was completed. The abstract
2365 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002366 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002367
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002368- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002369 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2370
Neal Norwitz708e51a2005-10-03 04:48:15 +00002371- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2372
Neal Norwitz11bd1192005-10-03 00:54:56 +00002373- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2374 Provide a warning when a directory is passed on the command line.
2375
Neal Norwitz40d37812005-10-02 01:48:49 +00002376- Fix segfault with invalid coding.
2377
2378- SF bug #772896: unknown encoding results in MemoryError.
2379
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002380- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002381 supported a __len__() method which evaluated to False when the iterator
2382 was empty.
2383
Guido van Rossum630db602005-09-20 18:49:54 +00002384- On 64-bit platforms, when __len__() returns a value that cannot be
2385 represented as a C int, raise OverflowError.
2386
Skip Montanarof8948ca2005-09-19 03:54:46 +00002387- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002388 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002389
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002390- SF bug #893549: parsing keyword arguments was broken with a few format
2391 codes.
2392
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002393- Changes donated by Elemental Security to make it work on AIX 5.3
2394 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2395 bug #105470: test_pwd fails on 64bit system (Opteron).
2396
Guido van Rossum539c6622005-09-14 17:49:54 +00002397- Changes donated by Elemental Security to make it work on HP-UX 11 on
2398 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2399
Georg Brandl4550b8d2005-08-26 06:43:52 +00002400- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002401 (fixes bug #1119418).
2402
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002403- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2404
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002405- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2406 exceptions that cause a function to exit.
2407
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002408- The implementation of set() and frozenset() was revised to use its
2409 own internal data structure. Memory consumption is reduced by 1/3
2410 and there are modest speed-ups as well. The API is unchanged.
2411
Tim Petersde7990b2005-07-17 23:45:23 +00002412- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2413
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002414- SF bug #1229429: PyObject_CallMethod failed to decrement some
2415 reference counts in some error exit cases.
2416
Tim Petersecc6e6a2005-07-10 22:30:55 +00002417- SF bug #1185883: Python's small-object memory allocator took over
2418 a block managed by the platform C library whenever a realloc specified
2419 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002420 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002421 portable way to copy data from the C-managed block into Python's
2422 small-object space without risking a memory fault. Python's small-object
2423 realloc now leaves such blocks under the control of the platform C
2424 realloc.
2425
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002426- SF bug #1232517: An overflow error was not detected properly when
2427 attempting to convert a large float to an int in os.utime().
2428
Raymond Hettinger3296e692005-06-29 23:29:56 +00002429- SF bug #1224347: hex longs now print with lowercase letters just
2430 like their int counterparts.
2431
Michael W. Hudson188d4362005-06-20 16:52:57 +00002432- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2433 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2434 interpreter states; back out that fix and do a better job (see
2435 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2436 for a longer write-up of the problem).
2437
Michael W. Hudsondf888462005-06-03 14:41:55 +00002438- SF patch #1180995: marshal now uses a binary format by default when
2439 serializing floats.
2440
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002441- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2442 the routines that promise to produce IEEE 754 binary representations
2443 of floats now simply copy bytes around.
2444
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002445- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2446 278.
2447
Brett Cannonc3647ac2005-04-26 03:45:26 +00002448- patch #1109424: int, long, float, complex, and unicode now check for the
2449 proper magic slot for type conversions when subclassed. Previously the
2450 magic slot was ignored during conversion. Semantics now match the way
2451 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002452 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002453 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002454 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002455
Barry Warsawc8d907c2005-04-19 23:43:40 +00002456- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2457 NULL, now raise an AttributeError when attempting to set or delete the
2458 attribute. Previously a TypeError was raised, but this was inconsistent
2459 with the equivalent pure-Python implementation.
2460
Michael W. Hudson774479c2005-04-18 08:46:17 +00002461- It is now safe to call PyGILState_Release() before
2462 PyEval_InitThreads() (note that if there is reason to believe there
2463 are multiple threads around you still must call PyEval_InitThreads()
2464 before using the Python API; this fix is for extension modules that
2465 have no way of knowing if Python is multi-threaded yet).
2466
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002467- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2468 disabled caused a crash.
2469
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002470- Bug #1165306: instancemethod_new allowed the creation of a method
2471 with im_class == im_self == NULL, which caused a crash when called.
2472
Tim Petersecc6e6a2005-07-10 22:30:55 +00002473- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002474 fixes the crash seen in bug #1165761
2475
Raymond Hettinger96229b12005-03-11 06:49:40 +00002476- Added two new builtins, any() and all().
2477
Brett Cannon409d8f22005-03-05 06:47:57 +00002478- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002479 (e.g., ``class C(): pass`` is no longer a syntax error).
2480 Patch #1176012 added support to the 'parser' module and 'compiler' package
2481 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002482
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002483- Patch #1115086: Support PY_LONGLONG in structmember.
2484
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002485- Bug #1155938: new style classes did not check that __init__() was
2486 returning None.
2487
Tim Petersecc6e6a2005-07-10 22:30:55 +00002488- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002489 ('\') with a specific error message.
2490
Martin v. Löwisff232d72005-03-03 09:24:38 +00002491- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2492
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002493- Bug #1124295: the __name__ attribute of file objects was
2494 inadvertently made inaccessible in restricted mode.
2495
Tim Petersecc6e6a2005-07-10 22:30:55 +00002496- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002497 an ferror() call.
2498
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002499- min() and max() now support key= arguments with the same meaning as in
2500 list.sort().
2501
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002502- The peephole optimizer now performs simple constant folding in expressions:
2503 (2+3) --> (5).
2504
Raymond Hettingera422c342005-01-11 03:03:27 +00002505- set and frozenset objects can now be marshalled. SF #1098985.
2506
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002507- Bug #1077106: Poor argument checking could cause memory corruption
2508 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002509
Jeremy Hyltonab630502005-02-04 18:44:06 +00002510- The parser did not complain about future statements in illegal
2511 positions. It once again reports a syntax error if a future
2512 statement occurs after anything other than a doc string.
2513
Neil Schemenauercf52c072005-08-12 17:34:58 +00002514- Change the %s format specifier for str objects so that it returns a
2515 unicode instance if the argument is not an instance of basestring and
2516 calling __str__ on the argument returns a unicode instance.
2517
Tim Petersf4e69282006-02-27 17:15:31 +00002518- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2519 current thread state when the auto-GIL-state machinery knows about
2520 it (since the thread state is being deleted, continuing to remember it
2521 can't help, but can hurt if another thread happens to get created with
2522 the same thread id).
2523
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002524Extension Modules
2525-----------------
2526
Georg Brandl43f08a82006-03-31 18:01:16 +00002527- Patch #1380952: fix SSL objects timing out on consecutive read()s

2530
Anthony Baxterfa869072006-03-20 05:21:58 +00002531- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2532 In addition, the existing ulaw code was updated.
2533
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002534- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002535 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002536
Neal Norwitz10be10c2006-03-16 06:50:13 +00002537- Everything under lib-old was removed. This includes the following modules:
2538 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002539 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002540 util, whatsound, whrandom, zmod
2541
2542- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2543
2544- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002545 is deprecated. The undocumented re.engine variable no longer exists.
2546
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002547- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2548 SS2 (single-shift 2) escape sequences correctly.
2549
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002550- The unicodedata module was updated to the 4.1 version of the Unicode
2551 database. The 3.2 version is still available as unicodedata.db_3_2_0
2552 for applications that require this specific version (such as IDNA).
2553
Neal Norwitzb62c4332006-03-04 18:35:47 +00002554- The timing module is no longer built by default. It was deprecated
2555 in PEP 4 in Python 2.0 or earlier.
2556
Guido van Rossum1968ad32006-02-25 22:38:04 +00002557- Patch 1433928: Added a new type, defaultdict, to the collections module.
2558 This uses the new __missing__ hook behavior added to dict (see above).
2559
Georg Brandldbd83392006-02-20 09:42:33 +00002560- Bug #854823: socketmodule now builds on Sun platforms even when
2561 INET_ADDRSTRLEN is not defined.
2562
Georg Brandlf4f44152006-02-18 22:29:33 +00002563- Patch #1393157: os.startfile() now has an optional argument to specify
2564 a "command verb" to invoke on the file.
2565
Neal Norwitz082b2df2006-02-07 07:04:46 +00002566- Bug #876637, prevent stack corruption when socket descriptor
2567 is larger than FD_SETSIZE.
2568
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002569- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2570 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2571 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
2572
Martin v. Löwis57a34e82006-02-04 19:12:37 +00002573- Patch #1422385: The nis module now supports access to domains other
2574 than the system default domain.
2575
Martin v. Löwis14694662006-02-03 12:54:16 +00002576- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2577 are reported, the limit on path name lengths is removed, and stat reports
2578 WindowsError now (instead of OSError).
2579
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002580- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
2581
Neal Norwitz62a21122006-01-25 05:21:55 +00002582- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
2583 before the env.
2584
Martin v. Löwis11017b12006-01-14 18:12:57 +00002585- Patch #1103116: Basic AF_NETLINK support.
2586
Neal Norwitz3b4fff82006-01-11 08:54:45 +00002587- Bug #1402308, (possible) segfault when using mmap.mmap(-1, ...)

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002714- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2715 been renamed to have only a single underscore prefix. This was done to
2716 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002717
Nick Coghlan43832302006-04-23 17:04:07 +00002718- PEP 338: new module runpy defines a run_module function to support
2719 executing modules which provide access to source code or a code object
2720 via the PEP 302 import mechanisms.
2721

2730 in attribute values.
2731
Anthony Baxterc51ee692006-04-01 00:57:31 +00002732- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002733 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002734 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002735 module will not be built.
2736
Tim Petersc17976e2006-04-01 00:26:53 +00002737- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2738 aren't officially supported here, and trying to use them will probably
2739 raise an exception some day. But dicts have been allowed, and "mostly
2740 worked", so support for them won't go away without warning.
2741
Georg Brandl338ef7d2006-03-31 18:42:16 +00002742- Bug #1445068: getpass.getpass() can now be given an explicit stream

2760
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002761- email 4.0 package now integrated. This is largely the same as the email 3.0
2762 package that was included in Python 2.3, except that PEP 8 module names are
2763 now used (e.g. mail.message instead of email.Message). The MIME classes
2764 have been moved to a subpackage (e.g. email.mime.text instead of
2765 email.MIMEText). The old names are still supported for now. Several
2766 deprecated Message methods have been removed and lots of bugs have been
2767 fixed. More details can be found in the email package documentation.
2768
Walter Dörwald40108c92006-03-27 08:15:44 +00002769- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2770 (a subclass of tuple) that provides incremental decoders and encoders
2771 (a way to use stateful codecs without the stream API). Python functions
2772 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2773 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2774 have been added.

2777 a ValueError instead of a StopIteration now (like file and cString.String do).
2778 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2779 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002853 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2854 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2855 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2856 Ronald L. Rivest offered this advice for Python:
2857
2858 "The consensus of researchers in this area (at least as
2859 expressed at the NIST Hash Function Workshop 10/31/05),
2860 is that SHA-256 is a good choice for the time being, but
2861 that research should continue, and other alternatives may
2862 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002863
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002864- Added a subset of Fredrik Lundh's ElementTree package. Available

2917 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002918 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002919

2941 to W3C name (404 -> 'Not Found'). RFE #1216944.
2942
Georg Brandl9e43acf2005-07-04 17:16:07 +00002943- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2944 as this can cause problems with apps closing all file descriptors.

2957 Bug #1224621.
2958
Raymond Hettinger68c04532005-06-10 11:05:19 +00002959- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002960 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002961 the generate_tokens() function now accepts a callable argument that
2962 terminates by raising StopIteration.
2963
Georg Brandl9166e1a2005-06-04 09:20:03 +00002964- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2972 class at all.
2973
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002974- distutils.commands.upload was added to support uploading distribution

2978 them to PyPI.
2979
Raymond Hettinger267b8682005-03-27 10:47:39 +00002980- decimal operator and comparison methods now return NotImplemented
2981 instead of raising a TypeError when interacting with other types. This
2982 allows other classes to implement __radd__ style methods and have them
2983 work as expected.
2984
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002985- Bug #1163325: Decimal infinities failed to hash. Attempting to
2986 hash a NaN raised an InvalidOperation instead of a TypeError.
2987
Tim Petersecc6e6a2005-07-10 22:30:55 +00002988- Patch #918101: Add tarfile open mode r|* for auto-detection of the

3022
Guido van Rossumd0641422005-02-03 15:01:24 +00003023- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3024 disables recursive traversal through instance attributes, which can
3025 be exploited in various ways.
3026
Tim Peterse3547fd2005-12-16 23:13:57 +00003027- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003028 flags on the HTTP listening socket.
3029
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003030- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3031 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3032

3039
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003040- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3041
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003042- Enhancements to the csv module:
3043
3044 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003045 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003046 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003047 + Dialect parameter parsing has been re-implemented to improve error
3048 reporting.
3049 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3050 dictates.
3051 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003052 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003053 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003054 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3055 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003056 + reader now allows \r characters to be quoted (previously it only allowed
3057 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003058 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003059 + Dialect classes passed to the module are no longer instantiated by
3060 the module before being parsed (the former validation scheme required
3061 this, but the mechanism was unreliable).
3062 + The dialect registry now contains instances of the internal
3063 C-coded dialect type, rather than references to python objects.
3064 + the internal c-coded dialect type is now immutable.
3065 + register_dialect now accepts the same keyword dialect specifications
3066 as the reader and writer, allowing the user to register dialects
3067 without first creating a dialect class.
3068 + a configurable limit to the size of parsed fields has been added -
3069 previously, an unmatched quote character could result in the entire
3070 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003071 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003072 the parser field size limit (returning the former limit). The initial
3073 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003074 + A line_num attribute has been added to the reader object, which tracks
3075 the number of lines read from the source iterator. This is not
3076 the same as the number of records returned, as records can span
3077 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003078 + reader and writer objects were not being registered with the cyclic-GC.
3079 This has been fixed.
3080
Brett Cannone6539c42005-01-08 02:43:53 +00003081- _DummyThread objects in the threading module now delete self.__block that is
3082 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3083 lock primitives tend to be limited in number and thus should not be wasted on
3084 a _DummyThread object. Fixes bug #1089632.
3085
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003086- The imghdr module now detects Exif files.
3087
Raymond Hettinger6065d322004-12-20 23:51:53 +00003088- StringIO.truncate() now correctly adjusts the size attribute.
3089 (Bug #951915).
3090
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003091- locale.py now uses an updated locale alias table (built using
3092 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3093 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003094 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003095
Raymond Hettinger3557f422004-12-07 12:02:02 +00003096- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3097
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003098- the pickle module no longer accepts the deprecated None option in the
3099 args tuple returned by __reduce__().
3100
Brett Cannon84667c02004-12-07 03:25:18 +00003101- optparse now optionally imports gettext. This allows its use in setup.py.
3102
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003103- the pickle module no longer uses the deprecated bin parameter.
3104
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003105- the shelve module no longer uses the deprecated binary parameter.
3106
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003107- the pstats module no longer uses the deprecated ignore() method.
3108
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003109- the filecmp module no longer uses the deprecated use_statcache argument.
3110
Raymond Hettinger664347b2004-12-04 21:21:53 +00003111- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3112 extended or overridden by subclasses. Formerly, the subclassed method would
3113 be ignored by the rest of the module. (Bug #1078905).
3114
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003115- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003116 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003117
Walter Dörwald36733692004-12-22 12:50:50 +00003118- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3119 once when a size argument is given. This prevents a buffer overflow in the
3120 tokenizer with very long source lines.
3121
Barry Warsaw538561e2006-01-01 21:48:54 +00003122- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3123 immediately after creating the object, without any intervening
3124 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003125
Skip Montanaro05885812005-01-16 20:48:27 +00003126- The reconvert.quote function can now emit triple-quoted strings. The
3127 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003128
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003129- ``UserString.MutableString`` now supports negative indices in
3130 ``__setitem__`` and ``__delitem__``
3131
Greg Ward40407942005-03-05 02:53:17 +00003132- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3133 correctly.
3134
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003135- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3136 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3137 character even if the user has passed a size parameter to get a proper
3138 line ending. Remove the special handling of a "\r\n" that has been split
3139 between two lines.
3140
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003141- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3142 about illegal code points. The codec now supports PEP 293 style error
3143 handlers.
3144
Walter Dörwald78a78b02005-09-01 12:04:29 +00003145- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003146 from the input stream, so that the output is a byte string in the correct
3147 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003148
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003149- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3150 considering it exactly like a '*'.
3151
Walter Dörwald007f8df2005-10-09 19:42:27 +00003152- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3153 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003154
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003155- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3156
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003157- Patch #1413711: Certain patterns of differences were making difflib
3158 touch the recursion limit.
3159
Walter Dörwald58917a62006-03-31 15:26:22 +00003160- Bug #947906: An object oriented interface has been added to the calendar
3161 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003162 called as a script (e.g. via ``python -mcalendar``). Localized month and
3163 weekday names can be ouput (even if an exotic encoding is used) using
3164 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003165
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003166Build
3167-----
3168
Neal Norwitz602d3392006-03-31 08:21:40 +00003169- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3170 by using -mieee gcc option.
3171

3173
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003174- Build support for Win64-AMD64 was added.
3175
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003176- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3177
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003178- Patch #881820: look for openpty and forkpty also in libbsd.
3179
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003180- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3181 The zlib module is now builtin on Windows.
3182
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003183- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3184
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003185- Bug #1189330: configure did not correctly determine the necessary
3186 value of LINKCC if python was built with GCC 4.0.
3187
Trent Mick8321b422005-07-26 02:29:21 +00003188- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3189 vulnerability in zlib 1.2.1 and 1.2.2.
3190
Brett Cannon08cd5982005-04-24 22:26:38 +00003191- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3192 flags that change binary compatibility. Changes were also made to
3193 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003194 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003195
Bob Ippolitoed233462005-03-29 13:47:59 +00003196- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3197 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3198 no longer exists). This configure patch makes things right.
3199
Martin v. Löwise2713be2005-03-08 15:03:08 +00003200- Bug #1158607: Build with --disable-unicode again.
3201
Brett Cannon46d96232005-02-16 00:07:19 +00003202- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3203 defined. Discovered as a result of not being able to build on OS X.
3204
Brett Cannon516592f2004-12-07 00:42:59 +00003205- setup.py now uses the directories specified in LDFLAGS using the -L option
3206 and in CPPFLAGS using the -I option for adding library and include
3207 directories, respectively, for compiling extension modules against. This has
3208 led to the core being compiled using the values in CPPFLAGS. It also removes
3209 the need for the special-casing of both DarwinPorts and Fink for darwin since
3210 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3211 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3212 Fink, ``-I/opt/local/include`` for DarwinPorts).
3213
Brett Cannon43802422005-02-10 20:48:03 +00003214- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3215 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3216 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3217 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003219C API
3220-----
3221
Tim Petersc9d78aa2006-03-26 23:27:58 +00003222- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3223 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3224 is obtained via the ``PyObject_`` family, it must be released via the
3225 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3226 always been officially true, but when Python's small-object allocator was
3227 introduced, an attempt was made to cater to a few extension modules
3228 discovered at the time that obtained memory via ``PyObject_New`` but
3229 released it via ``PyMem_DEL``. It's years later, and if such code still
3230 exists it will fail now (probably with segfaults, but calling wrong
3231 low-level memory management functions can yield many symptoms).
3232
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003233- Added a C API for set and frozenset objects.
3234
Raymond Hettinger66517482004-12-03 11:45:13 +00003235- Removed PyRange_New().
3236
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003237- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3238 mapping argument now. This string is used as a mapping table. Byte values
3239 greater than the length of the string and 0xFFFE are treated as undefined
3240 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00003246- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003247
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003248- Patch #1276356: New resource "urlfetch" is implemented. This enables
3249 even impatient people to run tests that require remote files.
