12Core and builtins
13-----------------
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000014
Guido van Rossumaa975432008-04-10 22:43:58 +000015- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
16 having a self-referential tuple, which is possible from C code. Nor did
17 object's tp_str consider that a type's tp_str could do something that could
18 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
19 respectively, fixed the issues. (Backport of r58288 from trunk.)
20
Georg Brandld9f1da02008-03-29 01:50:46 +000021- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
22 cannot be executed.
23
Amaury Forgeot d'Arc8432d862008-03-28 20:45:42 +000024- The compilation of a class nested in another class used to leak one
25 reference on the outer class name.
26
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000027- Issue #1477: With narrow Unicode builds, the unicode escape sequence
28 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
29 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
30 UTF-16 surrogates are generated in this case, like normal unicode literals
31 and the 'unicode-escape' codec.
32
Neal Norwitzb3635f92008-03-18 04:17:36 +000033- Issue #2321: use pymalloc for unicode object string data to reduce
34 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +000035
Sean Reifscheider4af861c2008-03-20 17:39:31 +000036- Issue #2238: Some syntax errors in *args and **kwargs expressions could give
37 bogus error messages.
38
Gregory P. Smith14acde32008-04-09 23:41:13 +000039- Issue #2587: In the C API, PyString_FromStringAndSize() takes a signed size
40 parameter but was not verifying that it was greater than zero. Values
41 less than zero will now raise a SystemError and return NULL to indicate a
42 bug in the calling C code.
43
Gregory P. Smith9aa040d2008-06-02 00:07:25 +000044- Issue #2588, #2589: Fix potential integer underflow and overflow
45 conditions in the PyOS_vsnprintf C API function.

Raymond Hettinger75ee9eb2008-06-16 01:49:18 +000051- Issue #3116 and #1792: Fix quadratic behavior in marshal.dumps().
52
Thomas Hellerf3bb2832008-04-25 19:55:19 +000053- Issue #2682: ctypes callback functions no longer contain a cyclic
54 reference to themselves.
55
Amaury Forgeot d'Arc8d904c32008-04-22 21:17:18 +000056- Issue #2670: Fix a failure in urllib2.build_opener(), when passed two
57 handlers that derive the same default base class.
58
Amaury Forgeot d'Arc198e3532008-03-27 23:41:59 +000059- Issue #2495: tokenize.untokenize now inserts a space between two consecutive
60 string literals; previously, ["" ""] was rendered as [""""], which is
61 incorrect python code.
62
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +000063- Issue #2482: Make sure that the coefficient of a Decimal is always
64 stored as a str instance, not as a unicode instance. This ensures
65 that str(Decimal) is always an instance of str. This fixes a
66 regression from Python 2.5.1 to Python 2.5.2.
67
Mark Dickinson26c25d92008-03-25 14:35:25 +000068- Issue #2478: fix failure of decimal.Decimal(0).sqrt()

74 platforms.
75
Georg Brandlab61dce2008-03-06 07:46:26 +000076- Bug #2220: handle rlcompleter attribute match failure more gracefully.
77
Martin v. Löwis0e305552008-03-06 07:14:26 +000078- Bug #1725737: In distutil's sdist, exclude RCS, CVS etc. also in the
79 root directory, and also exclude .hg, .git, .bzr, and _darcs.
80
Andrew M. Kuchling37d4f7b2008-02-23 19:06:54 +000081- Bug #1389051: imaplib causes excessive memory fragmentation when reading
82 large messages.
83
Andrew M. Kuchling664553a2008-02-23 19:30:59 +000084- Bug #1389051, 1092502: fix excessively large memory allocations when
85 calling .read() on a socket object wrapped with makefile().
86
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +000087- Bug #1433694: minidom's .normalize() failed to set .nextSibling for
88 last child element.
89
Gregory P. Smith26660402008-06-01 23:44:46 +000090- Issue #2791: subprocess.Popen.communicate explicitly closes its
91 stdout and stderr fds rather than leaving them open until the
92 instance is destroyed.

144-----------------
145
Martin v. Löwis73c01d42008-02-14 11:26:18 +0000146- Added checks for integer overflows, contributed by Google. Some are
147 only available if asserts are left in the code, in cases where they

973
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000974- Make _PyGILState_NoteThreadState() static, it was not used anywhere
975 outside of pystate.c and should not be necessary.
976
Brett Cannon19d76c52006-09-09 07:18:44 +0000977- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
978 allows calling unicode() on exceptions classes directly to succeed.
979
Georg Brandlecab6232006-09-06 06:47:02 +0000980- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
981 Also make sure that every exception class has __module__ set to
982 'exceptions'.
983
Georg Brandl37a9e572006-09-06 06:09:34 +0000984- Bug #1550983: emit better error messages for erroneous relative

994
Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000995- The return tuple from str.rpartition(sep) is (tail, sep, head) where
996 head is the original string if sep was not found.
997
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000998- Bug #1520864: unpacking singleton tuples in list comprehensions and
999 generator expressions (x for x, in ... ) works again. Fixing this problem
1000 required changing the .pyc magic number. This means that .pyc files
1001 generated before 2.5c2 will be regenerated.

Neal Norwitz24b6f202006-09-05 04:43:56 +00001116- Fix infinite recursion when subclassing long and overriding __hash__.
1117
1118- Fix concatenation (+=) of long strings.
1119
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001120- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001121 compared equal or unequal to a string and a UnicodeDecodeError
1122 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001123
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001124 Instead, the equal (==) and unequal (!=) comparison operators will
1125 now issue a UnicodeWarning and interpret the two objects as
1126 unequal. The UnicodeWarning can be filtered as desired using
1127 the warning framework, e.g. silenced completely, turned into an
1128 exception, logged, etc.
1129
1130 Note that compare operators other than equal and unequal will still
1131 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001132
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001133- Fix segfault when doing string formatting on subclasses of long.
1134
1135- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1136 with new-style classes.
1137
1138- Fix bug related to __len__ functions returning negative values with
1139 classic classes.
1140
1141- Patch #1538606, Fix __index__() clipping. There were some problems
1142 discovered with the API and how integers that didn't fit into Py_ssize_t
1143 were handled. This patch attempts to provide enough alternatives
1144 to effectively use __index__.
1145
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001146- Bug #1536021: __hash__ may now return long int; the final hash
1147 value is obtained by invoking hash on the long int.
1148
Thomas Hellerab1049c2006-08-08 17:37:00 +00001149- Bug #1536786: buffer comparison could emit a RuntimeWarning.

1152 sys.stdin is closed.
1153
Thomas Heller74d36f02006-08-04 18:17:40 +00001154- On Windows, the PyErr_Warn function is now exported from
1155 the Python dll again.
1156
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001157- Bug #1191458: tracing over for loops now produces a line event
1158 on each iteration. Fixing this problem required changing the .pyc
1159 magic number. This means that .pyc files generated before 2.5c1
1160 will be regenerated.
1161
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001162- Bug #1333982: string/number constants were inappropriately stored
1163 in the byte code and co_consts even if they were not used, ie
1164 immediately popped off the stack.
1165
Georg Brandle9462c72006-08-04 18:03:37 +00001166- Fixed a reference-counting problem in property().

1173 generated for generator expressions.
1174
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001175- The distutils version has been changed to 2.5.0. The change to
1176 keep it programmatically in sync with the Python version running
1177 the code (introduced in 2.5b3) has been reverted. It will continue
1178 to be maintained manually as static string literal.
1179
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001180- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001181 and this cannot be converted to the required C type, an exception is
1182 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001183 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001184
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001185- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001186 an exception.
1187
Tim Peterscbdd3502006-09-05 01:47:53 +00001188- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001189 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001190 workarounds for clocks with low resolution, to stop the code yielding
1191 duplicate UUIDs.
1192
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001193- Patch #1540892: site.py Quitter() class attempts to close sys.stdin

1221 raises the correct exceptions.
1222
Thomas Heller1ce433e2006-08-14 16:20:04 +00001223- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1224 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1225
Thomas Heller86720042006-08-14 11:17:48 +00001226- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1227 uses the _as_parameter_ attribute when objects are passed to foreign
1228 function calls. The ctypes version number was changed to 1.0.1.
1229
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001230- Bug #1530559, struct.pack raises TypeError where it used to convert.
1231 Passing float arguments to struct.pack when integers are expected
1232 now triggers a DeprecationWarning.

1256-----
1257
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001258- Bug #1535502, build _hashlib on Windows, and use masm assembler
1259 code in OpenSSL.
1260
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001261- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

1267-----
1268
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001269- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1270
Tim Peters4643c2f2006-08-10 22:45:34 +00001271- Bug #1069160. Internal correctness changes were made to
1272 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1273 the documentation was changed to state that the return value
1274 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001277What's New in Python 2.5 beta 3?
1278================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001279
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001280*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001281
1282Core and builtins
1283-----------------
1284
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001285- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001286 returned a long (see PEP 353).
1287
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001288- Bug #1515471: string.replace() accepts character buffers again.
1289
Neal Norwitz07aadb12006-07-30 06:55:48 +00001290- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1291 This provides the proper warning for struct.pack().
1292 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1293
Neal Norwitz0d62a062006-07-30 06:53:31 +00001294- Patch #1531113: Fix augmented assignment with yield expressions.
1295 Also fix a SystemError when trying to assign to yield expressions.
1296
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001297- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1298 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1299 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1300 excessive filesystem operations during imports.
1301
Tim Petersbc24eee2006-07-27 01:14:53 +00001302- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1303 operations on signed longs that are formally undefined by C.
1304 Unfortunately, at least one compiler now cares about that, so complicated
1305 the code to make that compiler happy again.
1306
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001307- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1308
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001309- Patch #1232023: Stop including current directory in search
1310 path on Windows.
1311
Neal Norwitze1fdb322006-07-21 05:32:28 +00001312- Fix some potential crashes found with failmalloc.
1313
Neal Norwitze7563102006-07-17 01:00:16 +00001314- Fix warnings reported by Klocwork's static analysis tool.
1315
Neal Norwitz84be93b2006-07-16 01:50:38 +00001316- Bug #1512814, Fix incorrect lineno's when code within a function
1317 had more than 255 blank lines.
1318
Georg Brandl9dceedb2006-07-12 15:31:17 +00001319- Patch #1521179: Python now accepts the standard options ``--help`` and
1320 ``--version`` as well as ``/?`` on Windows.
1321
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001322- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001323 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001324 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001325
Tim Peters112aad32006-07-19 00:03:19 +00001326- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001327 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001328 new ``sys._current_frames()`` returns a dictionary with one entry,
1329 mapping the faux "thread id" 0 to the current frame.
1330
Ronald Oussoren3075e162006-07-25 20:28:55 +00001331- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001332
Ronald Oussoren3075e162006-07-25 20:28:55 +00001333
Neal Norwitza1f10902006-07-12 07:28:29 +00001334Library
1335-------
1336
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001337- Correction of patch #1455898: In the mbcs decoder, set final=False
1338 for stream decoder, but final=True for the decode function.
1339
Georg Brandl07fec3a2006-08-01 18:49:24 +00001340- os.urandom no longer masks unrelated exceptions like SystemExit or
1341 KeyboardInterrupt.
1342
Tim Peters4643c2f2006-08-10 22:45:34 +00001343- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001344 shutil.copytree on Windows
1345
Georg Brandle34ac7c2006-07-30 11:07:23 +00001346- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1347 refers to file descriptors, not file objects.
1348
Tim Peterscbdd3502006-09-05 01:47:53 +00001349- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001350 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001351 #1513611, and probably others.
1352
Georg Brandledd9b0d2006-07-29 09:33:26 +00001353- Bug #1441397: The compiler module now recognizes module and function
1354 docstrings correctly as it did in Python 2.4.
1355
Tim Peters6f681472006-07-27 23:44:37 +00001356- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1357 lost that tests are sorted by name before being run. This rarely
1358 matters for well-written tests, but can create baffling symptoms if
1359 side effects from one test to the next affect outcomes. ``DocTestFinder``
1360 has been changed to sort the list of tests it returns.
1361
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001362- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001363 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001364
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001365- Bug #978833: Really close underlying socket in _socketobject.close.
1366
Georg Brandldb232dc2006-08-20 13:15:43 +00001367- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1368 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001369
Georg Brandlcf0c1722006-07-26 07:23:32 +00001370- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1371 to recursive calls and call it with the failing package name.
1372
Martin v. Löwis0b483032006-07-25 09:53:12 +00001373- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1374
Georg Brandlc13c34c2006-07-24 14:09:56 +00001375- Patch #1515343: Fix printing of deprecated string exceptions with a
1376 value in the traceback module.
1377
Greg Ward48fae7a2006-07-23 16:05:51 +00001378- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1379
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001380- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1381
Brett Cannoncaebe222006-07-18 04:41:36 +00001382- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1383 argument tuple. For arguments where zero is illegal, the value is forced to
1384 the minimum value that is correct. This is to support an undocumented but
1385 common way people used to fill in inconsequential information in the time
1386 tuple pre-2.4.
1387
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001388- Patch #1220874: Update the binhex module for Mach-O.
1389
Barry Warsawb110bad2006-07-21 14:51:07 +00001390- The email package has improved RFC 2231 support, specifically for
1391 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1392 (name*0=<blah>) parameter continuations. This may change the types of
1393 values returned from email.message.Message.get_param() and friends.
1394 Specifically in some cases where non-encoded continuations were used,
1395 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1396 will just return the string (since non-encoded continuations don't have
1397 charset and language parts).
1398
1399 Also, whereas % values were decoded in all parameter continuations, they are
1400 now only decoded in encoded parameter parts.
1401
Ronald Oussoren3075e162006-07-25 20:28:55 +00001402- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1403
1404- Bug #1517996: IDLE now longer shows the default Tk menu when a
1405 path browser, class browser or debugger is the frontmost window on MacOS X
1406
Barry Warsaw00decd72006-07-27 23:43:15 +00001407- Patch #1520294: Support for getset and member descriptors in types.py,
1408 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1409 of an object against these built-in types and more importantly, for getting
1410 their docstrings printed in the interactive interpreter's help() function.
1411

1415
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001416- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1417 a socket operation on a socket with a timeout, the exception will be
1418 caught correctly. Previously, the exception was not caught.
1419
Thomas Heller1393d6a2006-07-28 21:43:20 +00001420- Patch #1529514: The _ctypes extension is now compiled on more
1421 openbsd target platforms.
1422
Tim Peters9cab5932006-07-28 00:30:00 +00001423- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1424 a memory leak, affecting pickles and deep copies.
1425
Tim Petersbc24eee2006-07-27 01:14:53 +00001426- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001427 Paul Eggert.
1428
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001429- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1430
Thomas Hellerce049a02006-07-14 17:51:14 +00001431- Patch #1521817: Index range checking on ctypes arrays containing
1432 exactly one element enabled again. This allows iterating over these
1433 arrays, without the need to check the array size before.
1434
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001435- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001436 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001437 /dev/null in certain cases; this is now fixed.
1438
Thomas Heller47d7a062006-07-12 08:43:47 +00001439- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1440 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001441
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001442- Because of a misspelled preprocessor symbol, ctypes was always
1443 compiled without thread support; this is now fixed.
1444
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001445- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1446 methods now allow their database parameter to be None as the
1447 sleepycat API allows.
1448
Matt Flemingec926502006-07-28 11:27:27 +00001449- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1450 bluetooth API compared with Linux and FreeBSD.

1453-----
1454
1455- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1456 how long the test file should take to play. Now accepts taking 2.93 secs
1457 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1458
Georg Brandl4793aa32006-07-28 18:31:39 +00001459- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1460 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1461 run via ``regrtest.py``. Now they do.

1471- PythonLauncher now works correctly when the path to the script contains
1472 characters that are treated specially by the shell (such as quotes).
1473
1474- Bug #1527397: PythonLauncher now launches scripts with the working directory
1475 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001476 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001477 expect.

1485Core and builtins
1486-----------------
1487
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001488- Bug #1441486: The literal representation of -(sys.maxint - 1)
1489 again evaluates to a int object, not a long.
1490
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001491- Bug #1501934: The scope of global variables that are locally assigned
1492 using augmented assignment is now correctly determined.
1493
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001494- Bug #927248: Recursive method-wrapper objects can now safely
1495 be released.
1496
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001497- Bug #1417699: Reject locale-specific decimal point in float()
1498 and atof().
1499
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001500- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1501 omit a default "error" argument for NULL pointer. This allows
1502 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001503
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001504- Bug #1519018: 'as' is now validated properly in import statements.
1505
Neal Norwitz28746ab2006-07-09 22:14:42 +00001506- On 64 bit systems, int literals that use less than 64 bits are
1507 now ints rather than longs.
1508
Neal Norwitzed657552006-07-10 00:04:44 +00001509- Bug #1512814, Fix incorrect lineno's when code at module scope
1510 started after line 256.
1511
Tim Peters32a83612006-07-10 21:08:24 +00001512- New function ``sys._current_frames()`` returns a dict mapping thread
1513 id to topmost thread stack frame. This is for expert use, and is
1514 especially useful for debugging application deadlocks. The functionality
1515 was previously available in Fazal Majid's ``threadframe`` extension
1516 module, but it wasn't possible to do this in a wholly threadsafe way from
1517 an extension.
1518

1520-------
1521
Martin v. Löwis77621582006-07-30 13:27:31 +00001522- Bug #1257728: Mention Cygwin in distutils error message about a missing
1523 VS 2003.
1524

1526
Tim Peters32a83612006-07-10 21:08:24 +00001527- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001528 environment variable to be set in order to the SDK environment
1529 for finding the compiler, include files, etc.
1530
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001531- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1532
Nick Coghlan2d792252006-07-06 13:47:18 +00001533- warnings.py now ignores ImportWarning by default
1534
Thomas Woutersadd19112006-07-05 11:03:49 +00001535- string.Template() now correctly handles tuple-values. Previously,
1536 multi-value tuples would raise an exception and single-value tuples would
1537 be treated as the value they contain, instead.
1538
Martin v. Löwisede77f52006-07-03 13:01:35 +00001539- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1540 even if some data are received.
1541
Martin v. Löwis45482392006-07-03 12:28:58 +00001542- Bug #1267547: Put proper recursive setup.py call into the

1546 degrees and radians.
1547
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001548- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001549 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001550
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001551- Bug #1514703: Only setup canvas window in turtle when the canvas
1552 is created.
1553
Martin v. Löwis7596e832006-07-01 15:33:37 +00001554- Bug #1513223: .close() of a _socketobj now releases the underlying

1558 attribute values.
1559
1560- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1561 sgmllib ('[' and ']' were not accepted).
1562
Georg Brandl1be63af2006-06-28 20:23:25 +00001563- Fix a bug in the turtle module's end_fill function.
1564
Brett Cannon53ab5b72006-06-22 16:49:14 +00001565- Bug #1510580: The 'warnings' module improperly required that a Warning
1566 category be either a types.ClassType and a subclass of Warning. The proper
1567 check is just that it is a subclass with Warning as the documentation states.
1568
Georg Brandlad29e632006-06-21 17:45:17 +00001569- The compiler module now correctly compiles the new try-except-finally
1570 statement (bug #1509132).
1571
Neal Norwitz60373cd2006-06-22 06:30:50 +00001572- The wsgiref package is now installed properly on Unix.
1573
Vinay Sajip28e57612006-07-01 10:45:20 +00001574- A bug was fixed in logging.config.fileConfig() which caused a crash on
1575 shutdown when fileConfig() was called multiple times.
1576
Gerhard Häring762fbd32006-07-02 17:48:30 +00001577- The sqlite3 module did cut off data from the SQLite database at the first
1578 null character before sending it to a custom converter. This has been fixed
1579 now.
1580
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001581Extension Modules
1582-----------------
1583
Tim Peters112aad32006-07-19 00:03:19 +00001584- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1585 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1586 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001587
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001588- Assigning None to pointer type fields in ctypes structures possible
1589 overwrote the wrong fields, this is fixed now.
1590
1591- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1592 on non-Windows platforms.
1593
1594- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1595 integer or long, without range checking.
1596
1597- Patch #1517790: It is now possible to use custom objects in the ctypes
1598 foreign function argtypes sequence as long as they provide a from_param
1599 method, no longer is it required that the object is a ctypes type.
1600
1601- The '_ctypes' extension module now works when Python is configured
1602 with the --without-threads option.
1603
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001604- Bug #1513646: os.access on Windows now correctly determines write
1605 access, again.
1606
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001607- Bug #1512695: cPickle.loads could crash if it was interrupted with
1608 a KeyboardInterrupt.
1609
Neal Norwitza12aa882006-07-06 06:45:08 +00001610- Bug #1296433: parsing XML with a non-default encoding and
1611 a CharacterDataHandler could crash the interpreter in pyexpat.
1612
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001613- Patch #1516912: improve Modules support for OpenVMS.

1617
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001618- Automate Windows build process for the Win64 SSL module.
1619
Tim Peters32a83612006-07-10 21:08:24 +00001620- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001621 Previously, the slight difference could cause compilation errors of the
1622 'zlib' module on systems with more than one version of zlib.
1623
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001624- The MSI compileall step was fixed to also support a TARGETDIR
1625 with spaces in it.
1626
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001627- Bug #1517388: sqlite3.dll is now installed on Windows independent
1628 of Tcl/Tk.
1629
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001630- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001631 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +00001632
Neal Norwitzb15ac312006-06-29 04:10:08 +00001633Tests
1634-----
1635
1636- Call os.waitpid() at the end of tests that spawn child processes in order
1637 to minimize resources (zombies).
1638
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001639Documentation
1640-------------
1641
Nick Coghlan2d792252006-07-06 13:47:18 +00001642- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1643 documentation for the warnings module.
1644
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001645- Patch #1509163: MS Toolkit Compiler no longer available.
1646

Nick Coghlanc649ec52006-05-29 12:43:05 +00001650What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001651================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001652
Anthony Baxterd1136802006-06-19 12:04:15 +00001653*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001654
1655Core and builtins
1656-----------------
1657
Georg Brandla56b9152006-06-19 06:35:54 +00001658- Patch #1507676: Error messages returned by invalid abstract object operations
1659 (such as iterating over an integer) have been improved and now include the
1660 type of the offending object to help with debugging.
1661
Brett Cannonea3912b2006-06-13 21:46:41 +00001662- Bug #992017: A classic class that defined a __coerce__() method that returned
1663 its arguments swapped would infinitely recurse and segfault the interpreter.
1664
Neal Norwitz909eb122006-06-12 02:13:21 +00001665- Fix the socket tests so they can be run concurrently.
1666
Neal Norwitzb9845e72006-06-12 02:11:18 +00001667- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001668 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001669
Brett Cannon22565aa2006-06-09 22:31:23 +00001670- Bug #532646: object.__call__() will continue looking for the __call__
1671 attribute on objects until one without one is found. This leads to recursion
1672 when you take a class and set its __call__ attribute to an instance of the
1673 class. Originally fixed for classic classes, but this fix is for new-style.
1674 Removes the infinite_rec_3 crasher.
1675
Georg Brandl24250812006-06-09 18:45:48 +00001676- The string and unicode methods startswith() and endswith() now accept
1677 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1678
Brett Cannonde3b0522006-06-08 17:00:45 +00001679- Buffer objects, at the C level, never used the char buffer
1680 implementation even when the char buffer for the wrapped object was
1681 explicitly requested (originally returned the read or write buffer).
1682 Now a TypeError is raised if the char buffer is not present but is
1683 requested.
1684
Georg Brandlddbaa662006-06-04 21:56:52 +00001685- Patch #1346214: Statements like "if 0: suite" are now again optimized
1686 away like they were in Python 2.4.
1687
Georg Brandlb7c8f542006-05-27 12:30:25 +00001688- Builtin exceptions are now full-blown new-style classes instead of
1689 instances pretending to be classes, which speeds up exception handling
1690 by about 80% in comparison to 2.5a2.
1691
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001692- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1693 Unicode 4.1.
1694
Georg Brandlf4ef1162006-05-26 18:03:31 +00001695- Patch #921466: sys.path_importer_cache is now used to cache valid and
1696 invalid file paths for the built-in import machinery which leads to
1697 fewer open calls on startup.
1698
Tim Peters696cf432006-05-24 21:10:40 +00001699- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1700 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1701 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1702 the number of input digits (it was and remains linear-time for bases
1703 2, 4, 8, 16 and 32).
1704
Tim Petersb713ec22006-05-23 18:45:30 +00001705- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1706 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1707 an integer close to ``sys.maxint``. This was repaired by patch
1708 #1335972, which also gives a nice speedup.
1709
Richard Jonescebbefc2006-05-23 18:28:17 +00001710- Patch #1337051: reduced size of frame objects.
1711
1712- PyErr_NewException now accepts a tuple of base classes as its
1713 "base" parameter.
1714
Richard Jones7c88dcc2006-05-23 10:37:38 +00001715- Patch #876206: function call speedup by retaining allocated frame
1716 objects.
1717
Georg Brandl7b90e162006-05-18 07:01:27 +00001718- Bug #1462152: file() now checks more thoroughly for invalid mode
1719 strings and removes a possible "U" before passing the mode to the
1720 C library function.
1721
Neal Norwitz1004a532006-05-15 07:17:23 +00001722- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1723
Neal Norwitz373f0a72006-05-15 07:04:36 +00001724- Bug #1487966: Fix SystemError with conditional expression in assignment
1725
Martin v. Löwis879768d2006-05-11 13:28:43 +00001726- WindowsError now has two error code attributes: errno, which carries
1727 the error values from errno.h, and winerror, which carries the error
1728 values from winerror.h. Previous versions put the winerror.h values
1729 (from GetLastError()) into the errno attribute.
1730
Martin v. Löwis77736712006-05-04 05:51:03 +00001731- Patch #1475845: Raise IndentationError for unexpected indent.
1732
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001733- Patch #1479181: split open() and file() from being aliases for each other.
1734
Tim Peters44bd9862006-06-01 13:49:23 +00001735- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1736 methods were always silently ignored by dictionaries when comparing keys.
1737 They are now passed through (except when using the C API function
1738 ``PyDict_GetItem()``, whose semantics did not change).
1739
1740- Bug #1456209: In some obscure cases it was possible for a class with a
1741 custom ``__eq__()`` method to confuse dict internals when class instances
1742 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1743 No, you don't have any code that did this ;-)

1747
Trent Mick960a3f82006-06-28 20:30:41 +00001748- Bug #1295808: expat symbols should be namespaced in pyexpat
1749
1750- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1751
Brett Cannon6ee7d012006-06-08 16:23:04 +00001752- Change binascii.hexlify to accept a read-only buffer instead of only a char
1753 buffer and actually follow its documentation.
1754
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001755- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1756
Nick Coghlanc649ec52006-05-29 12:43:05 +00001757- Patch #1478788 (modified version): The functional extension module has
1758 been renamed to _functools and a functools Python wrapper module added.
1759 This provides a home for additional function related utilities that are
1760 not specifically about functional programming. See PEP 309.
1761
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001762- Patch #1493701: performance enhancements for struct module.

1765
Georg Brandl8d3342b2006-05-16 07:38:27 +00001766- Patch #1435422: zlib's compress and decompress objects now have a
1767 copy() method.
1768
Andrew MacIntyre92913322006-06-13 15:04:24 +00001769- Patch #1454481: thread stack size is now tunable at runtime for thread
1770 enabled builds on Windows and systems with Posix threads support.
1771
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001772- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1773 (up to the system limit of 32K characters).
1774
1775- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1776 As a result, these functions now raise WindowsError instead of OSError.
1777
Tim Peters7a822da2006-05-25 21:50:17 +00001778- ``time.clock()`` on Win64 should use the high-performance Windows
1779 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1780 Windows platforms).
1781
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001782- Calling Tk_Init twice is refused if the first call failed as that
1783 may deadlock.
1784
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001785- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1786 accept it without potentially using an uninitialized pointer.
1787
1788- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1789 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1790 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001791
Gregory P. Smith372b5832006-06-05 18:48:21 +00001792- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001793 [pybsddb project SF patch number 1466734]
1794
Gregory P. Smith372b5832006-06-05 18:48:21 +00001795- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1796 parameter is supplied. [SF pybsddb bug #1477863]
1797
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001798- bsddb: the __len__ method of a DB object has been fixed to return correct
1799 results. It could previously incorrectly return 0 in some cases.
1800 Fixes SF bug 1493322 (pybsddb bug 1184012).
1801
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001802- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1803 aborts the db transaction safely when a modifier callback fails.
1804 Fixes SF python patch/bug #1408584.
1805
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001806- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001807 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001808 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1809 database calls that would previously deadlock. [SF python bug #775414]
1810
Vinay Sajip28e57612006-07-01 10:45:20 +00001811- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1833 mime.types file for determining MIME types.
1834
Georg Brandl2605ca82006-06-14 06:08:31 +00001835- Bug #1339007: Shelf objects now don't raise an exception in their

1837
Martin v. Löwisd8251432006-06-14 05:21:04 +00001838- Patch #1455898: The MBCS codec now supports the incremental mode for
1839 double-byte encodings.
1840
Tim Peters43898b42006-06-14 04:09:25 +00001841- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1842 guarantee that adjacent triples in the return list always describe
1843 non-adjacent blocks. Previously, a pair of matching blocks could end
1844 up being described by multiple adjacent triples that formed a partition
1845 of the matching pair.
1846
Greg Ward0e0c9f42006-06-11 16:24:11 +00001847- Bug #1498146: fix optparse to handle Unicode strings in option help,
1848 description, and epilog.
1849

1853 clarify docs.
1854
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001855- The wsgiref package has been added to the standard library.
1856
Nick Coghlan676725d2006-06-08 13:54:49 +00001857- The functions update_wrapper() and wraps() have been added to the functools
1858 module. These make it easier to copy relevant metadata from the original
1859 function when writing wrapper functions.
1860
Tim Petersd6a9eef2006-06-05 01:48:21 +00001861- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1862 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001863
Martin v. Löwis3f767792006-06-04 19:36:28 +00001864- Patch #1359618: Speed up charmap encoder by using a trie structure
1865 for lookup.
1866
Tim Petersd609b1a2006-06-02 23:22:51 +00001867- The functions in the ``pprint`` module now sort dictionaries by key
1868 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1869 if and only if its display required more than one line, although that
1870 wasn't documented. The new behavior increases predictability; e.g.,
1871 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1872
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001873- Patch #1497027: try HTTP digest auth before basic auth in urllib2

1875
Georg Brandl2b330372006-05-28 20:23:12 +00001876- Patch #1496206: improve urllib2 handling of passwords with respect to
1877 default HTTP and HTTPS ports.
1878

1880
Bob Ippolito7298f272006-05-23 18:43:47 +00001881- Patch #1281707: speed up gzip.readline.
1882
Georg Brandlb89316f2006-05-17 15:51:16 +00001883- Patch #1180296: Two new functions were added to the locale module:
1884 format_string() to get the effect of "format % items" but locale-aware,
1885 and currency() to format a monetary number with currency sign.
1886
Georg Brandle3a25832006-05-17 14:56:04 +00001887- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1888 and several features added, such as speed and geometry control.
1889
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001890- Patch #1488881: add support for external file objects in bz2 compressed
1891 tarfiles.
1892
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001893- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1894 stdout arguments, making it possible to redirect input and output
1895 for remote debugging.
1896
1897- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1898 a couple of issues, notably handling of long file names using the
1899 GNU LONGNAME extension.
1900
1901- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1902 new flag when ``name`` is already the name of an option flag.
1903
1904- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1905 package.
1906
1907- Patch #1472854: make the rlcompleter.Completer class usable on non-
1908 UNIX platforms.

1949-----------------
1950
Thomas Heller1b046642006-04-18 18:51:06 +00001951- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1952 by converting these apis from macros into exported functions again:
1953
1954 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1955 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1956 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

1958 PyRun_String Py_CompileString
1959
Martin v. Löwis45294a92006-04-18 06:24:08 +00001960- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1961
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001962- All uses of PyStructSequence_InitType have been changed to initialize
1963 the type objects only once, even if the interpreter is initialized
1964 multiple times.
1965
Neal Norwitz61546162006-04-14 05:20:28 +00001966- Bug #1454485, array.array('u') could crash the interpreter. This was
1967 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1968 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1969
1970- Py_UNICODE is unsigned. It was always documented as unsigned, but
1971 due to a bug had a signed value in previous versions.
1972
Tim Peters3a5e8b12006-04-11 01:44:07 +00001973- Patch #837242: ``id()`` of any Python object always gives a positive
1974 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1975 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001976 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001977 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001978
Tim Peters3a5e8b12006-04-11 01:44:07 +00001979 def __hash__(self):
1980 return id(self) # WRONG
1981
1982 because a hash result must be a (short) Python int but it was always
1983 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001984 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001985 was always usable as a hash value before this patch. That's no longer
1986 necessarily so.
1987
1988- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001989 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001990 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001991 #1454844)
1992
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001993- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1994 involving generators that have paused outside of any ``try`` or ``with``
1995 blocks. (In 2.5a1, a paused generator that was part of a reference
1996 cycle could not be garbage collected, regardless of whether it was
1997 paused in a ``try`` or ``with`` block.)

2026 of the process using the returncode attribute, instead of
2027 abusing errno.
2028
Tim Peters711bf302006-04-25 03:31:36 +00002029- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2030 a doctest to be skipped (the code is not run, and the expected output
2031 or exception is ignored).
2032
Nick Coghlanda2268f2006-04-24 04:37:15 +00002033- Fixed contextlib.nested to cope with exceptions being raised and
2034 caught inside exit handlers.
2035
Greg Wardab05edc2006-04-23 03:47:58 +00002036- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2037 hex, octal, or binary; add ``append_const`` action; keep going if
2038 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2039 added ``epilog`` for better help generation).
2040
Tim Peters21fbd572006-04-21 21:18:10 +00002041- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2042 called from a thread spawned as a side effect of importing a module.
2043
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002044- The pydoc module now supports documenting packages contained in
2045 .zip or .egg files.
2046
2047- The pkgutil module now has several new utility functions, such
2048 as ``walk_packages()`` to support working with packages that are either
2049 in the filesystem or zip files.
2050
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002051- The mailbox module can now modify and delete messages from
2052 mailboxes, in addition to simply reading them. Thanks to Gregory
2053 K. Johnson for writing the code, and to the 2005 Google Summer of
2054 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002055
Tim Petersc7605f22006-04-17 21:12:33 +00002056- The ``__del__`` method of class ``local`` in module ``_threading_local``
2057 returned before accomplishing any of its intended cleanup.
2058
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002059- Patch #790710: Add breakpoint command lists in pdb.
2060

2081
Anthony Baxter51bcb682006-04-05 14:51:42 +00002082Build
2083-----
2084
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002085- The Makefile now has a reindent target, which runs reindent.py on
2086 the library.
2087
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002088- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002091
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002092- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2093 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002094 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002095 CXX from --with-cxx-main, see description in README.
2096
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002097- Patch #1429775: Link extension modules with the shared libpython.
2098
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002099- Fixed a libffi build problem on MIPS systems.
2100
Tim Peters8931ff12006-05-13 23:28:20 +00002101- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2102 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2103 and "%zu" for unsigned integers of type ``size_t``.
2104
Anthony Baxter51bcb682006-04-05 14:51:42 +00002105Tests
2106-----
2107
Nick Coghlanda2268f2006-04-24 04:37:15 +00002108- test_contextlib now checks contextlib.nested can cope with exceptions
2109 being raised and caught inside exit handlers.
2110
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002111- test_cmd_line now checks operation of the -m and -c command switches
2112
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002113- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2114 it separately and by hand. It also wasn't cleaning up its changes to
2115 the current Decimal context.
2116
Thomas Woutersabd08882006-04-26 15:53:30 +00002117- regrtest.py now has a -M option to run tests that test the new limits of
2118 containers, on 64-bit architectures. Running these tests is only sensible
2119 on 64-bit machines with more than two gigabytes of memory. The argument
2120 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002128Documentation
2129-------------
2130
Tim Petersb06d28c2006-05-12 01:57:59 +00002131- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2132
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002133- PEP 343: Added Context Types section to the library reference
2134 and attempted to bring other PEP 343 related documentation into
2135 line with the implementation and/or python-dev discussions.
2136
Tim Peters8dc73d22006-04-24 02:03:16 +00002137- Bug #1337990: clarified that ``doctest`` does not support examples
2138 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002141What's New in Python 2.5 alpha 1?
2142=================================
2143
Anthony Baxterebed3f62006-04-03 15:03:44 +00002144*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002145
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002146Core and builtins
2147-----------------
2148
Nick Coghlan43832302006-04-23 17:04:07 +00002149- PEP 338: -m command line switch now delegates to runpy.run_module
2150 allowing it to support modules in packages and zipfiles
2151
Martin v. Löwisc661b882006-04-20 04:54:23 +00002152- On Windows, .DLL is not an accepted file name extension for
2153 extension modules anymore; extensions are only found if they
2154 end in .PYD.
2155
Martin v. Löwisea62d252006-04-03 10:56:49 +00002156- Bug #1421664: sys.stderr.encoding is now set to the same value as
2157 sys.stdout.encoding.
2158
Neal Norwitz92e212f2006-04-03 04:48:37 +00002159- __import__ accepts keyword arguments.
2160
Georg Brandlccadf842006-03-31 18:54:53 +00002161- Patch #1460496: round() now accepts keyword arguments.
2162
Anthony Baxter262c00a2006-03-30 10:53:17 +00002163- Fixed bug #1459029 - unicode reprs were double-escaped.
2164
Hye-Shik Changd478f342006-03-23 12:32:36 +00002165- Patch #1396919: The system scope threads are reenabled on FreeBSD
2166 5.4 and later versions.
2167
Neal Norwitze98ccf62006-03-23 05:39:47 +00002168- Bug #1115379: Compiling a Unicode string with an encoding declaration
2169 now gives a SyntaxError.
2170
Georg Brandlabd1ff82006-03-18 07:59:59 +00002171- Previously, Python code had no easy way to access the contents of a
2172 cell object. Now, a ``cell_contents`` attribute has been added
2173 (closes patch #1170323).
2174
Tim Peterscf79aac2006-03-16 01:14:46 +00002175- Patch #1123430: Python's small-object allocator now returns an arena to
2176 the system ``free()`` when all memory within an arena becomes unused
2177 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2178 freed. Some applications will see a drop in virtual memory size now,
2179 especially long-running applications that, from time to time, temporarily
2180 use a large number of small objects. Note that when Python returns an
2181 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002182 platform C library will in turn return that memory to the operating system.
2183 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002184 appears to be effective at least on Microsoft C and gcc-based systems.
2185 Thanks to Evan Jones for hard work and patience.
2186
Georg Brandl533ff6f2006-03-08 18:09:27 +00002187- Patch #1434038: property() now uses the getter's docstring if there is
2188 no "doc" argument given. This makes it possible to legitimately use
2189 property() as a decorator to produce a read-only property.
2190
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002191- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2192 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2193 of requiring an int or long in slicing and a few other contexts, enabling
2194 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2195
Neal Norwitz995acdf2006-03-07 05:01:00 +00002196- Fixed various bugs reported by Coverity's Prevent tool.
2197
Brett Cannonbf364092006-03-01 04:25:17 +00002198- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2199 new exception base class, BaseException, which has a new message attribute.
2200 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2201 Raising a string exception now raises a DeprecationWarning.
2202
Thomas Woutersfb609f42006-02-28 16:37:25 +00002203- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2204 explicitly relative, using 'from .module import name' to mean 'from the same
2205 package as this module is in. Imports without dots still default to the
2206 old relative-then-absolute, unless 'from __future__ import
2207 absolute_import' is used.
2208
Brett Cannona7446e32006-02-27 23:39:10 +00002209- Properly check if 'warnings' raises an exception (usually when a filter set
2210 to "error" is triggered) when raising a warning for raising string
2211 exceptions.
2212
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002213- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002214 The name was removed from Include/code.h.
2215
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002216- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002217
Guido van Rossum1968ad32006-02-25 22:38:04 +00002218- Patch 1433928:
2219 - The copy module now "copies" function objects (as atomic objects).
2220 - dict.__getitem__ now looks for a __missing__ hook before raising
2221 KeyError.
2222
Tim Peters84ef21c2006-02-28 20:39:06 +00002223- PEP 343: with statement implemented. Needs ``from __future__ import
2224 with_statement``. Use of 'with' as a variable will generate a warning.
2225 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002226 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002227 The following objects have __context__ methods:
2228 - The built-in file type.
2229 - The thread.LockType type.
2230 - The following types defined by the threading module:
2231 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2232 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002233
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002234- Fix the encodings package codec search function to only search
2235 inside its own package. Fixes problem reported in patch #1433198.
2236
2237 Note: Codec packages should implement and register their own
2238 codec search function. PEP 100 has the details.
2239
Tim Peters9ea89d22006-06-04 03:26:02 +00002240- PEP 353: Using ``Py_ssize_t`` as the index type.
2241
2242- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2243 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2244 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2245 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2246 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002247
Neal Norwitzfc76d632006-01-10 06:03:13 +00002248- Patch #1400181, fix unicode string formatting to not use the locale.
2249 This is how string objects work. u'%f' could use , instead of .
2250 for the decimal point. Now both strings and unicode always use periods.
2251
Neal Norwitz671b9e32006-01-09 07:07:12 +00002252- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2253 configure would break checking curses.h.
2254
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002255- Bug #959576: The pwd module is now builtin. This allows Python to be
2256 built on UNIX platforms without $HOME set.
2257
Neal Norwitzc10978f2005-12-19 06:07:16 +00002258- Bug #1072182, fix some potential problems if characters are signed.
2259
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002260- Bug #889500, fix line number on SyntaxWarning for global declarations.
2261
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002262- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2263
Neal Norwitze7214a12005-12-18 05:03:17 +00002264- Support for converting hex strings to floats no longer works.
2265 This was not portable. float('0x3') now raises a ValueError.
2266
Barry Warsaw2a38a862005-12-18 01:27:35 +00002267- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002268 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002269 is now displayed in interactive prompt banner.
2270
Georg Brandlfa166682005-12-17 21:45:17 +00002271- Implementation of PEP 341 - Unification of try/except and try/finally.
2272 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002273 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002274
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002275- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2276 now encodes backslash correctly.
2277
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002278- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2279
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002280- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002281 and long longs.
2282
Neal Norwitz67715f02005-11-09 06:59:35 +00002283- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002284 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002285 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002286
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002287- Replaced most Unicode charmap codecs with new ones using the
2288 new Unicode translate string feature in the builtin charmap
2289 codec; the codecs were created from the mapping tables available
2290 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2291 encodings now include a mapping for the Apple logo)
2292
Tim Peterse3547fd2005-12-16 23:13:57 +00002293- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002294
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002295- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002296
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002297- A new AST parser implementation was completed. The abstract
2298 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002299 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002300
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002301- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002302 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2303
Neal Norwitz708e51a2005-10-03 04:48:15 +00002304- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2305
Neal Norwitz11bd1192005-10-03 00:54:56 +00002306- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2307 Provide a warning when a directory is passed on the command line.
2308
Neal Norwitz40d37812005-10-02 01:48:49 +00002309- Fix segfault with invalid coding.
2310
2311- SF bug #772896: unknown encoding results in MemoryError.
2312
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002313- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002314 supported a __len__() method which evaluated to False when the iterator
2315 was empty.
2316
Guido van Rossum630db602005-09-20 18:49:54 +00002317- On 64-bit platforms, when __len__() returns a value that cannot be
2318 represented as a C int, raise OverflowError.
2319
Skip Montanarof8948ca2005-09-19 03:54:46 +00002320- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002321 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002322
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002323- SF bug #893549: parsing keyword arguments was broken with a few format
2324 codes.
2325
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002326- Changes donated by Elemental Security to make it work on AIX 5.3
2327 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2328 bug #105470: test_pwd fails on 64bit system (Opteron).
2329
Guido van Rossum539c6622005-09-14 17:49:54 +00002330- Changes donated by Elemental Security to make it work on HP-UX 11 on
2331 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2332
Georg Brandl4550b8d2005-08-26 06:43:52 +00002333- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002334 (fixes bug #1119418).
2335
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002336- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2337
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002338- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2339 exceptions that cause a function to exit.
2340
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002341- The implementation of set() and frozenset() was revised to use its
2342 own internal data structure. Memory consumption is reduced by 1/3
2343 and there are modest speed-ups as well. The API is unchanged.
2344
Tim Petersde7990b2005-07-17 23:45:23 +00002345- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2346
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002347- SF bug #1229429: PyObject_CallMethod failed to decrement some
2348 reference counts in some error exit cases.
2349
Tim Petersecc6e6a2005-07-10 22:30:55 +00002350- SF bug #1185883: Python's small-object memory allocator took over
2351 a block managed by the platform C library whenever a realloc specified
2352 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002353 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002354 portable way to copy data from the C-managed block into Python's
2355 small-object space without risking a memory fault. Python's small-object
2356 realloc now leaves such blocks under the control of the platform C
2357 realloc.
2358
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002359- SF bug #1232517: An overflow error was not detected properly when
2360 attempting to convert a large float to an int in os.utime().
2361
Raymond Hettinger3296e692005-06-29 23:29:56 +00002362- SF bug #1224347: hex longs now print with lowercase letters just
2363 like their int counterparts.
2364
Michael W. Hudson188d4362005-06-20 16:52:57 +00002365- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2366 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2367 interpreter states; back out that fix and do a better job (see
2368 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2369 for a longer write-up of the problem).
2370
Michael W. Hudsondf888462005-06-03 14:41:55 +00002371- SF patch #1180995: marshal now uses a binary format by default when
2372 serializing floats.
2373
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002374- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2375 the routines that promise to produce IEEE 754 binary representations
2376 of floats now simply copy bytes around.
2377
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002378- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2379 278.
2380
Brett Cannonc3647ac2005-04-26 03:45:26 +00002381- patch #1109424: int, long, float, complex, and unicode now check for the
2382 proper magic slot for type conversions when subclassed. Previously the
2383 magic slot was ignored during conversion. Semantics now match the way
2384 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002385 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002386 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002387 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002388
Barry Warsawc8d907c2005-04-19 23:43:40 +00002389- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2390 NULL, now raise an AttributeError when attempting to set or delete the
2391 attribute. Previously a TypeError was raised, but this was inconsistent
2392 with the equivalent pure-Python implementation.
2393
Michael W. Hudson774479c2005-04-18 08:46:17 +00002394- It is now safe to call PyGILState_Release() before
2395 PyEval_InitThreads() (note that if there is reason to believe there
2396 are multiple threads around you still must call PyEval_InitThreads()
2397 before using the Python API; this fix is for extension modules that
2398 have no way of knowing if Python is multi-threaded yet).
2399
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002400- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2401 disabled caused a crash.
2402
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002403- Bug #1165306: instancemethod_new allowed the creation of a method
2404 with im_class == im_self == NULL, which caused a crash when called.
2405
Tim Petersecc6e6a2005-07-10 22:30:55 +00002406- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002407 fixes the crash seen in bug #1165761
2408
Raymond Hettinger96229b12005-03-11 06:49:40 +00002409- Added two new builtins, any() and all().
2410
Brett Cannon409d8f22005-03-05 06:47:57 +00002411- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002412 (e.g., ``class C(): pass`` is no longer a syntax error).
2413 Patch #1176012 added support to the 'parser' module and 'compiler' package
2414 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002415
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002416- Patch #1115086: Support PY_LONGLONG in structmember.
2417
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002418- Bug #1155938: new style classes did not check that __init__() was
2419 returning None.
2420
Tim Petersecc6e6a2005-07-10 22:30:55 +00002421- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002422 ('\') with a specific error message.
2423
Martin v. Löwisff232d72005-03-03 09:24:38 +00002424- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2425
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002426- Bug #1124295: the __name__ attribute of file objects was
2427 inadvertently made inaccessible in restricted mode.
2428
Tim Petersecc6e6a2005-07-10 22:30:55 +00002429- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002430 an ferror() call.
2431
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002432- min() and max() now support key= arguments with the same meaning as in
2433 list.sort().
2434
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002435- The peephole optimizer now performs simple constant folding in expressions:
2436 (2+3) --> (5).
2437
Raymond Hettingera422c342005-01-11 03:03:27 +00002438- set and frozenset objects can now be marshalled. SF #1098985.
2439
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002440- Bug #1077106: Poor argument checking could cause memory corruption
2441 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002442
Jeremy Hyltonab630502005-02-04 18:44:06 +00002443- The parser did not complain about future statements in illegal
2444 positions. It once again reports a syntax error if a future
2445 statement occurs after anything other than a doc string.
2446
Neil Schemenauercf52c072005-08-12 17:34:58 +00002447- Change the %s format specifier for str objects so that it returns a
2448 unicode instance if the argument is not an instance of basestring and
2449 calling __str__ on the argument returns a unicode instance.
2450
Tim Petersf4e69282006-02-27 17:15:31 +00002451- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2452 current thread state when the auto-GIL-state machinery knows about
2453 it (since the thread state is being deleted, continuing to remember it
2454 can't help, but can hurt if another thread happens to get created with
2455 the same thread id).
2456
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002457Extension Modules

2474
2475- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2476
2477- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002478 is deprecated. The undocumented re.engine variable no longer exists.

2482
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002483- The unicodedata module was updated to the 4.1 version of the Unicode
2484 database. The 3.2 version is still available as unicodedata.db_3_2_0
2485 for applications that require this specific version (such as IDNA).
2486
Neal Norwitzb62c4332006-03-04 18:35:47 +00002487- The timing module is no longer built by default. It was deprecated
2488 in PEP 4 in Python 2.0 or earlier.
2489
Guido van Rossum1968ad32006-02-25 22:38:04 +00002490- Patch 1433928: Added a new type, defaultdict, to the collections module.

2492
Georg Brandldbd83392006-02-20 09:42:33 +00002493- Bug #854823: socketmodule now builds on Sun platforms even when

2508
Martin v. Löwis14694662006-02-03 12:54:16 +00002509- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2510 are reported, the limit on path name lengths is removed, and stat reports
2511 WindowsError now (instead of OSError).
2512

2588 the request code argument, which results in more C-like behaviour
2589 for large or negative values.
2590
Tim Petersecc6e6a2005-07-10 22:30:55 +00002591- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2632 args tuple returned by __reduce__().
2633
Raymond Hettingerb2594052004-12-05 09:25:51 +00002634- itertools.islice() now accepts None for the start and step arguments.

Tim Peters112aad32006-07-19 00:03:19 +00002646
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002647- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2648 been renamed to have only a single underscore prefix. This was done to
2649 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002650
Nick Coghlan43832302006-04-23 17:04:07 +00002651- PEP 338: new module runpy defines a run_module function to support
2652 executing modules which provide access to source code or a code object
2653 via the PEP 302 import mechanisms.
2654
Anthony Baxter93f5b932006-04-03 08:05:07 +00002655- The email module's parsedate_tz function now sets the daylight savings
2656 flag to -1 (unknown) since it can't tell from the date whether it should

2663 in attribute values.
2664
Anthony Baxterc51ee692006-04-01 00:57:31 +00002665- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002666 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002667 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002668 module will not be built.
2669
Tim Petersc17976e2006-04-01 00:26:53 +00002670- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2671 aren't officially supported here, and trying to use them will probably
2672 raise an exception some day. But dicts have been allowed, and "mostly
2673 worked", so support for them won't go away without warning.
2674
Georg Brandl338ef7d2006-03-31 18:42:16 +00002675- Bug #1445068: getpass.getpass() can now be given an explicit stream
2676 argument to specify where to write the prompt.
2677
Georg Brandl22ec80b2006-03-31 18:25:44 +00002678- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2687 to make it easier to monitor when daemon threads have completed
2688 processing all enqueued tasks. Patch #1455676.
2689
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002690- popen2.Popen objects now preserve the command in a .cmd attribute.

2693
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002694- email 4.0 package now integrated. This is largely the same as the email 3.0
2695 package that was included in Python 2.3, except that PEP 8 module names are
2696 now used (e.g. mail.message instead of email.Message). The MIME classes
2697 have been moved to a subpackage (e.g. email.mime.text instead of
2698 email.MIMEText). The old names are still supported for now. Several
2699 deprecated Message methods have been removed and lots of bugs have been
2700 fixed. More details can be found in the email package documentation.
2701
Walter Dörwald40108c92006-03-27 08:15:44 +00002702- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2703 (a subclass of tuple) that provides incremental decoders and encoders
2704 (a way to use stateful codecs without the stream API). Python functions
2705 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2706 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2707 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002708
Walter Dörwald067db482006-03-15 22:17:27 +00002709- Patch #1359365: Calling next() on a closed StringIO.String object raises
2710 a ValueError instead of a StopIteration now (like file and cString.String do).
2711 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2712 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002713
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002714- A regrtest option -w was added to re-run failed tests in verbose mode.

2726 and helpful context managers nested() and closing().
2727

Martin v. Löwis3e865952006-01-24 15:51:21 +00002762 specifications, raises IOErrors when proxies for unsupported protocols
2763 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002786 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2787 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2788 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2789 Ronald L. Rivest offered this advice for Python:
2790
2791 "The consensus of researchers in this area (at least as
2792 expressed at the NIST Hash Function Workshop 10/31/05),
2793 is that SHA-256 is a good choice for the time being, but
2794 that research should continue, and other alternatives may
2795 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002796
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002797- Added a subset of Fredrik Lundh's ElementTree package. Available

2874 to W3C name (404 -> 'Not Found'). RFE #1216944.
2875
Georg Brandl9e43acf2005-07-04 17:16:07 +00002876- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2877 as this can cause problems with apps closing all file descriptors.
2878
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002879- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002880 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00002881

Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002889- The tokenize module now detects and reports indentation errors.
2890 Bug #1224621.
2891
Raymond Hettinger68c04532005-06-10 11:05:19 +00002892- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002893 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002894 the generate_tokens() function now accepts a callable argument that
2895 terminates by raising StopIteration.
2896
Georg Brandl9166e1a2005-06-04 09:20:03 +00002897- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2898
Georg Brandl268e61c2005-06-03 14:28:50 +00002899- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2900 component of the path.
2901
Skip Montanaro174dd222005-05-14 20:54:16 +00002902- Patch #1120353: The xmlrpclib module provides better, more transparent,
2903 support for datetime.{datetime,date,time} objects. With use_datetime set
2904 to True, applications shouldn't have to fiddle with the DateTime wrapper
2905 class at all.
2906
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002907- distutils.commands.upload was added to support uploading distribution
2908 files to PyPI.
2909
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002910- distutils.commands.register now encodes the data as UTF-8 before posting
2911 them to PyPI.
2912
Raymond Hettinger267b8682005-03-27 10:47:39 +00002913- decimal operator and comparison methods now return NotImplemented
2914 instead of raising a TypeError when interacting with other types. This
2915 allows other classes to implement __radd__ style methods and have them
2916 work as expected.
2917
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002918- Bug #1163325: Decimal infinities failed to hash. Attempting to
2919 hash a NaN raised an InvalidOperation instead of a TypeError.
2920
Tim Petersecc6e6a2005-07-10 22:30:55 +00002921- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2955
Guido van Rossumd0641422005-02-03 15:01:24 +00002956- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2957 disables recursive traversal through instance attributes, which can
2958 be exploited in various ways.
2959
Tim Peterse3547fd2005-12-16 23:13:57 +00002960- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002961 flags on the HTTP listening socket.
2962
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002963- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2964 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2965
Fred Drakefbdeaad2006-07-29 16:56:15 +00002966- Patches #893642, #1039083: add allow_none, encoding arguments to
2967 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002968
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002969- Bug #1110478: Revert os.environ.update to do putenv again.

Thomas Hellerd6c6e222005-01-20 19:20:16 +00002971- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2972
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002973- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2974
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002975- Enhancements to the csv module:
2976
2977 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002978 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002979 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002980 + Dialect parameter parsing has been re-implemented to improve error
2981 reporting.
2982 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2983 dictates.
2984 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002985 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002986 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002987 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2988 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002989 + reader now allows \r characters to be quoted (previously it only allowed
2990 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002991 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002992 + Dialect classes passed to the module are no longer instantiated by
2993 the module before being parsed (the former validation scheme required
2994 this, but the mechanism was unreliable).
2995 + The dialect registry now contains instances of the internal
2996 C-coded dialect type, rather than references to python objects.
2997 + the internal c-coded dialect type is now immutable.
2998 + register_dialect now accepts the same keyword dialect specifications
2999 as the reader and writer, allowing the user to register dialects
3000 without first creating a dialect class.
3001 + a configurable limit to the size of parsed fields has been added -
3002 previously, an unmatched quote character could result in the entire
3003 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003004 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003005 the parser field size limit (returning the former limit). The initial
3006 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003007 + A line_num attribute has been added to the reader object, which tracks
3008 the number of lines read from the source iterator. This is not
3009 the same as the number of records returned, as records can span
3010 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003011 + reader and writer objects were not being registered with the cyclic-GC.
3012 This has been fixed.
3013
Brett Cannone6539c42005-01-08 02:43:53 +00003014- _DummyThread objects in the threading module now delete self.__block that is
3015 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3016 lock primitives tend to be limited in number and thus should not be wasted on
3017 a _DummyThread object. Fixes bug #1089632.
3018
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003019- The imghdr module now detects Exif files.
3020
Raymond Hettinger6065d322004-12-20 23:51:53 +00003021- StringIO.truncate() now correctly adjusts the size attribute.
3022 (Bug #951915).
3023
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003024- locale.py now uses an updated locale alias table (built using
3025 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3026 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003027 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003028
Raymond Hettinger3557f422004-12-07 12:02:02 +00003029- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3030
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003031- the pickle module no longer accepts the deprecated None option in the
3032 args tuple returned by __reduce__().
3033
Brett Cannon84667c02004-12-07 03:25:18 +00003034- optparse now optionally imports gettext. This allows its use in setup.py.
3035
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003036- the pickle module no longer uses the deprecated bin parameter.
3037
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003038- the shelve module no longer uses the deprecated binary parameter.
3039
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003040- the pstats module no longer uses the deprecated ignore() method.
3041
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003042- the filecmp module no longer uses the deprecated use_statcache argument.
3043
Raymond Hettinger664347b2004-12-04 21:21:53 +00003044- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3045 extended or overridden by subclasses. Formerly, the subclassed method would
3046 be ignored by the rest of the module. (Bug #1078905).
3047
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003048- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003049 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003050
Walter Dörwald36733692004-12-22 12:50:50 +00003051- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3052 once when a size argument is given. This prevents a buffer overflow in the
3053 tokenizer with very long source lines.
3054
Barry Warsaw538561e2006-01-01 21:48:54 +00003055- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3056 immediately after creating the object, without any intervening
3057 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003058
Skip Montanaro05885812005-01-16 20:48:27 +00003059- The reconvert.quote function can now emit triple-quoted strings. The
3060 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003061
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003062- ``UserString.MutableString`` now supports negative indices in
3063 ``__setitem__`` and ``__delitem__``
3064
Greg Ward40407942005-03-05 02:53:17 +00003065- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3066 correctly.
3067
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003068- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3069 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3070 character even if the user has passed a size parameter to get a proper
3071 line ending. Remove the special handling of a "\r\n" that has been split
3072 between two lines.
3073
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003074- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3075 about illegal code points. The codec now supports PEP 293 style error
3076 handlers.
3077
Walter Dörwald78a78b02005-09-01 12:04:29 +00003078- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003079 from the input stream, so that the output is a byte string in the correct
3080 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003081
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003082- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3083 considering it exactly like a '*'.
3084
Walter Dörwald007f8df2005-10-09 19:42:27 +00003085- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3086 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003087
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003088- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3089
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003090- Patch #1413711: Certain patterns of differences were making difflib
3091 touch the recursion limit.
3092
Walter Dörwald58917a62006-03-31 15:26:22 +00003093- Bug #947906: An object oriented interface has been added to the calendar
3094 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003095 called as a script (e.g. via ``python -mcalendar``). Localized month and
3096 weekday names can be ouput (even if an exotic encoding is used) using
3097 special classes that use unicode.

3123
Brett Cannon08cd5982005-04-24 22:26:38 +00003124- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3125 flags that change binary compatibility. Changes were also made to
3126 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003127 compilation of the interpreter and of C extensions through distutils.

Martin v. Löwise2713be2005-03-08 15:03:08 +00003133- Bug #1158607: Build with --disable-unicode again.
3134
Brett Cannon46d96232005-02-16 00:07:19 +00003135- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3136 defined. Discovered as a result of not being able to build on OS X.
3137
Brett Cannon516592f2004-12-07 00:42:59 +00003138- setup.py now uses the directories specified in LDFLAGS using the -L option
3139 and in CPPFLAGS using the -I option for adding library and include
3140 directories, respectively, for compiling extension modules against. This has
3141 led to the core being compiled using the values in CPPFLAGS. It also removes
3142 the need for the special-casing of both DarwinPorts and Fink for darwin since
3143 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3144 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3145 Fink, ``-I/opt/local/include`` for DarwinPorts).
3146
Brett Cannon43802422005-02-10 20:48:03 +00003147- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3148 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3149 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3150 Closes bug #1096244. Thanks Gregory Bond.

3153-----
3154
Tim Petersc9d78aa2006-03-26 23:27:58 +00003155- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3156 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3157 is obtained via the ``PyObject_`` family, it must be released via the
3158 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3159 always been officially true, but when Python's small-object allocator was
3160 introduced, an attempt was made to cater to a few extension modules
3161 discovered at the time that obtained memory via ``PyObject_New`` but
3162 released it via ``PyMem_DEL``. It's years later, and if such code still
3163 exists it will fail now (probably with segfaults, but calling wrong
3164 low-level memory management functions can yield many symptoms).
3165
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003166- Added a C API for set and frozenset objects.
3167
Raymond Hettinger66517482004-12-03 11:45:13 +00003168- Removed PyRange_New().
3169
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003170- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3171 mapping argument now. This string is used as a mapping table. Byte values
3172 greater than the length of the string and 0xFFFE are treated as undefined
3173 mappings.

Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003181- Patch #1276356: New resource "urlfetch" is implemented. This enables
3182 even impatient people to run tests that require remote files.
