22
Jeffrey Yasskin478a1aa2008-12-10 07:28:12 +000023- Issue #4589: Propagated an exception thrown by a context manager's

29
Benjamin Peterson6f08e852008-11-03 15:19:35 +000030- Issue #4048: The parser module now correctly validates relative imports.
31
Amaury Forgeot d'Arc3b335ff2008-10-30 21:40:05 +000032- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
33 method does not return iterators for the 4th and 5th items.
34
Amaury Forgeot d'Arcb50f9922008-09-26 22:46:01 +000035- Issue #3967: Fixed a crash in the count() and find() methods of string-like
36 objects, when the "start" parameter is a huge value.
37
Benjamin Petersond1c7d072008-09-25 20:46:05 +000038- Issue #3936: The parser warnings for using "as" and "with" as variable names

Neal Norwitz83ac0142008-07-28 05:06:20 +000049- Issue #2620: Overflow checking when allocating or reallocating memory
50 was not always being done properly in some python types and extension
51 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have

53 would previously leak memory on the error path when such an allocation
54 failed have been fixed.

68 another thread's dictionary.
69

72
Guido van Rossumaa975432008-04-10 22:43:58 +000073- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
74 having a self-referential tuple, which is possible from C code. Nor did
75 object's tp_str consider that a type's tp_str could do something that could
76 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
77 respectively, fixed the issues. (Backport of r58288 from trunk.)

83 reference on the outer class name.
84
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000085- Issue #1477: With narrow Unicode builds, the unicode escape sequence
86 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
87 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
88 UTF-16 surrogates are generated in this case, like normal unicode literals
89 and the 'unicode-escape' codec.
90
Neal Norwitzb3635f92008-03-18 04:17:36 +000091- Issue #2321: use pymalloc for unicode object string data to reduce
92 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +000093
Sean Reifscheider4af861c2008-03-20 17:39:31 +000094- Issue #2238: Some syntax errors in *args and **kwargs expressions could give
95 bogus error messages.
96
Gregory P. Smith14acde32008-04-09 23:41:13 +000097- Issue #2587: In the C API, PyString_FromStringAndSize() takes a signed size
98 parameter but was not verifying that it was greater than zero. Values
99 less than zero will now raise a SystemError and return NULL to indicate a
100 bug in the calling C code.
101
Gregory P. Smith9aa040d2008-06-02 00:07:25 +0000102- Issue #2588, #2589: Fix potential integer underflow and overflow
103 conditions in the PyOS_vsnprintf C API function.
104
Gregory P. Smithcae7f882008-09-07 06:44:12 +0000105- Issue #1204: The configure script now tests for additional libraries
106 that may be required when linking against readline. This fixes issues
107 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
Georg Brandld9f1da02008-03-29 01:50:46 +0000108
Gregory P. Smitha7a94a02008-09-22 00:22:44 +0000109- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
110 library targets in the Makefile.

Amaury Forgeot d'Arc22679b82008-08-18 19:33:42 +0000148- Issue #2234: distutils failed for some versions of the cygwin compiler. The
149 version reported by these tools does not necessarily follow the python
150 version numbering scheme, so the module is less strict when parsing it.
151
Hirokazu Yamamoto1d63a452008-08-17 09:49:10 +0000152- Issue #2222: Fixed reference leak when occured os.rename()

308-----------------
309
Martin v. Löwis73c01d42008-02-14 11:26:18 +0000310- Added checks for integer overflows, contributed by Google. Some are
311 only available if asserts are left in the code, in cases where they
312 can't be triggered from Python code.
313

315 collections.defaultdict, if its default_factory is set to a bound method.
316
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000317- Issue #1920: "while 0" statements were completely removed by the compiler,
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000318 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000319 the condition is false. Now the compiler correctly emits bytecode for the
320 "else" suite.

324 borrowed_ref_[34].py (not in tracker).
325
326- Fix for #1303614 and #1174712 backported from the trunk:
327 __dict__ descriptor abuse for subclasses of built-in types;
328 subclassing from both ModuleType and another built-in types.

335 folding optimization. This was a regression from Python 2.4.
336
Georg Brandl78d50cc2008-01-21 18:36:54 +0000337- Issue #1882: when compiling code from a string, encoding cookies in the

348 format code incorrectly truncated the length to an int, even when
349 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect

Neal Norwitz29a5fdb2006-09-05 02:21:38 +00001159- The return tuple from str.rpartition(sep) is (tail, sep, head) where
1160 head is the original string if sep was not found.
1161
Neal Norwitz3b3aae02006-09-05 03:56:01 +00001162- Bug #1520864: unpacking singleton tuples in list comprehensions and
1163 generator expressions (x for x, in ... ) works again. Fixing this problem
1164 required changing the .pyc magic number. This means that .pyc files
1165 generated before 2.5c2 will be regenerated.

1277Core and builtins
1278-----------------
1279
Neal Norwitz24b6f202006-09-05 04:43:56 +00001280- Fix infinite recursion when subclassing long and overriding __hash__.
1281
1282- Fix concatenation (+=) of long strings.
1283
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001284- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001285 compared equal or unequal to a string and a UnicodeDecodeError
1286 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001287
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001288 Instead, the equal (==) and unequal (!=) comparison operators will
1289 now issue a UnicodeWarning and interpret the two objects as
1290 unequal. The UnicodeWarning can be filtered as desired using
1291 the warning framework, e.g. silenced completely, turned into an
1292 exception, logged, etc.
1293
1294 Note that compare operators other than equal and unequal will still
1295 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001296
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001297- Fix segfault when doing string formatting on subclasses of long.
1298
1299- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1300 with new-style classes.
1301
1302- Fix bug related to __len__ functions returning negative values with
1303 classic classes.
1304
1305- Patch #1538606, Fix __index__() clipping. There were some problems
1306 discovered with the API and how integers that didn't fit into Py_ssize_t
1307 were handled. This patch attempts to provide enough alternatives
1308 to effectively use __index__.
1309
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001310- Bug #1536021: __hash__ may now return long int; the final hash
1311 value is obtained by invoking hash on the long int.
1312
Thomas Hellerab1049c2006-08-08 17:37:00 +00001313- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1314
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001315- Bug #1535165: fixed a segfault in input() and raw_input() when
1316 sys.stdin is closed.
1317
Thomas Heller74d36f02006-08-04 18:17:40 +00001318- On Windows, the PyErr_Warn function is now exported from
1319 the Python dll again.
1320
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001321- Bug #1191458: tracing over for loops now produces a line event
1322 on each iteration. Fixing this problem required changing the .pyc
1323 magic number. This means that .pyc files generated before 2.5c1
1324 will be regenerated.
1325
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001326- Bug #1333982: string/number constants were inappropriately stored
1327 in the byte code and co_consts even if they were not used, ie
1328 immediately popped off the stack.
1329
Georg Brandle9462c72006-08-04 18:03:37 +00001330- Fixed a reference-counting problem in property().

1334-------
1335
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001336- Fix a bug in the ``compiler`` package that caused invalid code to be
1337 generated for generator expressions.
1338
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001339- The distutils version has been changed to 2.5.0. The change to
1340 keep it programmatically in sync with the Python version running
1341 the code (introduced in 2.5b3) has been reverted. It will continue
1342 to be maintained manually as static string literal.
1343
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001344- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001345 and this cannot be converted to the required C type, an exception is
1346 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001347 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001348
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001349- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001350 an exception.
1351
Tim Peterscbdd3502006-09-05 01:47:53 +00001352- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001353 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001354 workarounds for clocks with low resolution, to stop the code yielding
1355 duplicate UUIDs.
1356
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001357- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1358 before raising SystemExit, allowing IDLE to honor quit() and exit().
1359
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001360- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1361
Georg Brandl7a1af772006-08-14 21:55:28 +00001362- Patch #1536071: trace.py should now find the full module name of a
1363 file correctly even on Windows.
1364
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001365- logging's atexit hook now runs even if the rest of the module has
1366 already been cleaned up.
1367
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001368- Bug #1112549, fix DoS attack on cgi.FieldStorage.

1371 str(exception) raised an exception.
1372
Neil Schemenauer06ded092006-08-04 16:20:30 +00001373- Fix a bug in the ``compiler`` package that caused invalid code to be

1391 uses the _as_parameter_ attribute when objects are passed to foreign
1392 function calls. The ctypes version number was changed to 1.0.1.
1393
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001394- Bug #1530559, struct.pack raises TypeError where it used to convert.

Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001452- Bug #1515471: string.replace() accepts character buffers again.
1453
Neal Norwitz07aadb12006-07-30 06:55:48 +00001454- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1455 This provides the proper warning for struct.pack().
1456 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1457
Neal Norwitz0d62a062006-07-30 06:53:31 +00001458- Patch #1531113: Fix augmented assignment with yield expressions.
1459 Also fix a SystemError when trying to assign to yield expressions.
1460
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001461- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1462 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1463 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1464 excessive filesystem operations during imports.
1465
Tim Petersbc24eee2006-07-27 01:14:53 +00001466- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1467 operations on signed longs that are formally undefined by C.
1468 Unfortunately, at least one compiler now cares about that, so complicated
1469 the code to make that compiler happy again.
1470
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001471- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1472
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001473- Patch #1232023: Stop including current directory in search
1474 path on Windows.
1475
Neal Norwitze1fdb322006-07-21 05:32:28 +00001476- Fix some potential crashes found with failmalloc.
1477
Neal Norwitze7563102006-07-17 01:00:16 +00001478- Fix warnings reported by Klocwork's static analysis tool.
1479
Neal Norwitz84be93b2006-07-16 01:50:38 +00001480- Bug #1512814, Fix incorrect lineno's when code within a function
1481 had more than 255 blank lines.
1482
Georg Brandl9dceedb2006-07-12 15:31:17 +00001483- Patch #1521179: Python now accepts the standard options ``--help`` and
1484 ``--version`` as well as ``/?`` on Windows.
1485
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001486- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001487 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001488 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001489
Tim Peters112aad32006-07-19 00:03:19 +00001490- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001491 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001492 new ``sys._current_frames()`` returns a dictionary with one entry,
1493 mapping the faux "thread id" 0 to the current frame.
1494
Ronald Oussoren3075e162006-07-25 20:28:55 +00001495- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

1499-------
1500
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001501- Correction of patch #1455898: In the mbcs decoder, set final=False
1502 for stream decoder, but final=True for the decode function.
1503
Georg Brandl07fec3a2006-08-01 18:49:24 +00001504- os.urandom no longer masks unrelated exceptions like SystemExit or
1505 KeyboardInterrupt.
1506
Tim Peters4643c2f2006-08-10 22:45:34 +00001507- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001508 shutil.copytree on Windows
1509
Georg Brandle34ac7c2006-07-30 11:07:23 +00001510- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1511 refers to file descriptors, not file objects.
1512
Tim Peterscbdd3502006-09-05 01:47:53 +00001513- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001514 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001515 #1513611, and probably others.
1516
Georg Brandledd9b0d2006-07-29 09:33:26 +00001517- Bug #1441397: The compiler module now recognizes module and function
1518 docstrings correctly as it did in Python 2.4.
1519
Tim Peters6f681472006-07-27 23:44:37 +00001520- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1521 lost that tests are sorted by name before being run. This rarely
1522 matters for well-written tests, but can create baffling symptoms if
1523 side effects from one test to the next affect outcomes. ``DocTestFinder``
1524 has been changed to sort the list of tests it returns.
1525
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001526- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001527 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001528
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001529- Bug #978833: Really close underlying socket in _socketobject.close.
1530
Georg Brandldb232dc2006-08-20 13:15:43 +00001531- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1532 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001533
Georg Brandlcf0c1722006-07-26 07:23:32 +00001534- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1535 to recursive calls and call it with the failing package name.
1536
Martin v. Löwis0b483032006-07-25 09:53:12 +00001537- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1538
Georg Brandlc13c34c2006-07-24 14:09:56 +00001539- Patch #1515343: Fix printing of deprecated string exceptions with a
1540 value in the traceback module.
1541
Greg Ward48fae7a2006-07-23 16:05:51 +00001542- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1543
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001544- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1545
Brett Cannoncaebe222006-07-18 04:41:36 +00001546- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1547 argument tuple. For arguments where zero is illegal, the value is forced to
1548 the minimum value that is correct. This is to support an undocumented but
1549 common way people used to fill in inconsequential information in the time
1550 tuple pre-2.4.
1551
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001552- Patch #1220874: Update the binhex module for Mach-O.
1553
Barry Warsawb110bad2006-07-21 14:51:07 +00001554- The email package has improved RFC 2231 support, specifically for
1555 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1556 (name*0=<blah>) parameter continuations. This may change the types of
1557 values returned from email.message.Message.get_param() and friends.
1558 Specifically in some cases where non-encoded continuations were used,
1559 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1560 will just return the string (since non-encoded continuations don't have
1561 charset and language parts).
1562
1563 Also, whereas % values were decoded in all parameter continuations, they are
1564 now only decoded in encoded parameter parts.
1565
Ronald Oussoren3075e162006-07-25 20:28:55 +00001566- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1567
1568- Bug #1517996: IDLE now longer shows the default Tk menu when a
1569 path browser, class browser or debugger is the frontmost window on MacOS X
1570
Barry Warsaw00decd72006-07-27 23:43:15 +00001571- Patch #1520294: Support for getset and member descriptors in types.py,
1572 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1573 of an object against these built-in types and more importantly, for getting
1574 their docstrings printed in the interactive interpreter's help() function.

1578-----------------
1579
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001580- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1581 a socket operation on a socket with a timeout, the exception will be
1582 caught correctly. Previously, the exception was not caught.
1583
Thomas Heller1393d6a2006-07-28 21:43:20 +00001584- Patch #1529514: The _ctypes extension is now compiled on more
1585 openbsd target platforms.
1586
Tim Peters9cab5932006-07-28 00:30:00 +00001587- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1588 a memory leak, affecting pickles and deep copies.
1589
Tim Petersbc24eee2006-07-27 01:14:53 +00001590- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1594
Thomas Hellerce049a02006-07-14 17:51:14 +00001595- Patch #1521817: Index range checking on ctypes arrays containing
1596 exactly one element enabled again. This allows iterating over these
1597 arrays, without the need to check the array size before.
1598
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001599- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001600 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001601 /dev/null in certain cases; this is now fixed.
1602
Thomas Heller47d7a062006-07-12 08:43:47 +00001603- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1604 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001605
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001606- Because of a misspelled preprocessor symbol, ctypes was always
1607 compiled without thread support; this is now fixed.
1608
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001609- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1610 methods now allow their database parameter to be None as the
1611 sleepycat API allows.
1612
Matt Flemingec926502006-07-28 11:27:27 +00001613- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1614 bluetooth API compared with Linux and FreeBSD.
1615
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001616Tests
1617-----
1618
1619- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1620 how long the test file should take to play. Now accepts taking 2.93 secs
1621 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1622
Georg Brandl4793aa32006-07-28 18:31:39 +00001623- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1624 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1625 run via ``regrtest.py``. Now they do.

1634
1635- PythonLauncher now works correctly when the path to the script contains
1636 characters that are treated specially by the shell (such as quotes).
1637
1638- Bug #1527397: PythonLauncher now launches scripts with the working directory
1639 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001640 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001641 expect.

1651
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001652- Bug #1441486: The literal representation of -(sys.maxint - 1)
1653 again evaluates to a int object, not a long.
1654
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001655- Bug #1501934: The scope of global variables that are locally assigned
1656 using augmented assignment is now correctly determined.
1657
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001658- Bug #927248: Recursive method-wrapper objects can now safely
1659 be released.
1660
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001661- Bug #1417699: Reject locale-specific decimal point in float()
1662 and atof().
1663
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001664- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1665 omit a default "error" argument for NULL pointer. This allows
1666 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001667
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001668- Bug #1519018: 'as' is now validated properly in import statements.
1669
Neal Norwitz28746ab2006-07-09 22:14:42 +00001670- On 64 bit systems, int literals that use less than 64 bits are
1671 now ints rather than longs.
1672
Neal Norwitzed657552006-07-10 00:04:44 +00001673- Bug #1512814, Fix incorrect lineno's when code at module scope
1674 started after line 256.
1675
Tim Peters32a83612006-07-10 21:08:24 +00001676- New function ``sys._current_frames()`` returns a dict mapping thread
1677 id to topmost thread stack frame. This is for expert use, and is
1678 especially useful for debugging application deadlocks. The functionality
1679 was previously available in Fazal Majid's ``threadframe`` extension
1680 module, but it wasn't possible to do this in a wholly threadsafe way from
1681 an extension.

1687 VS 2003.
1688
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001689- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1690
Tim Peters32a83612006-07-10 21:08:24 +00001691- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK

1698
Thomas Woutersadd19112006-07-05 11:03:49 +00001699- string.Template() now correctly handles tuple-values. Previously,
1700 multi-value tuples would raise an exception and single-value tuples would
1701 be treated as the value they contain, instead.
1702
Martin v. Löwisede77f52006-07-03 13:01:35 +00001703- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

Martin v. Löwis45482392006-07-03 12:28:58 +00001706- Bug #1267547: Put proper recursive setup.py call into the
1707 spec file generated by bdist_rpm.
1708
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001709- Bug #1514693: Update turtle's heading when switching between
1710 degrees and radians.
1711
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001712- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001713 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001714

1716 is created.
1717
Martin v. Löwis7596e832006-07-01 15:33:37 +00001718- Bug #1513223: .close() of a _socketobj now releases the underlying
1719 socket again, which then gets closed as it becomes unreferenced.
1720
Fred Drake10497c82006-06-29 02:57:48 +00001721- Bug #1504333: Make sgmllib support angle brackets in quoted
1722 attribute values.

Georg Brandl1be63af2006-06-28 20:23:25 +00001727- Fix a bug in the turtle module's end_fill function.
1728
Brett Cannon53ab5b72006-06-22 16:49:14 +00001729- Bug #1510580: The 'warnings' module improperly required that a Warning
1730 category be either a types.ClassType and a subclass of Warning. The proper
1731 check is just that it is a subclass with Warning as the documentation states.
1732
Georg Brandlad29e632006-06-21 17:45:17 +00001733- The compiler module now correctly compiles the new try-except-finally
1734 statement (bug #1509132).
1735
Neal Norwitz60373cd2006-06-22 06:30:50 +00001736- The wsgiref package is now installed properly on Unix.
1737
Vinay Sajip28e57612006-07-01 10:45:20 +00001738- A bug was fixed in logging.config.fileConfig() which caused a crash on
1739 shutdown when fileConfig() was called multiple times.
1740
Gerhard Häring762fbd32006-07-02 17:48:30 +00001741- The sqlite3 module did cut off data from the SQLite database at the first
1742 null character before sending it to a custom converter. This has been fixed
1743 now.
1744

1746-----------------
1747
Tim Peters112aad32006-07-19 00:03:19 +00001748- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1749 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1750 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001751
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001752- Assigning None to pointer type fields in ctypes structures possible
1753 overwrote the wrong fields, this is fixed now.
1754
1755- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1756 on non-Windows platforms.
1757
1758- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1759 integer or long, without range checking.
1760
1761- Patch #1517790: It is now possible to use custom objects in the ctypes
1762 foreign function argtypes sequence as long as they provide a from_param
1763 method, no longer is it required that the object is a ctypes type.
1764
1765- The '_ctypes' extension module now works when Python is configured
1766 with the --without-threads option.
1767
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001768- Bug #1513646: os.access on Windows now correctly determines write
1769 access, again.
1770
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001771- Bug #1512695: cPickle.loads could crash if it was interrupted with
1772 a KeyboardInterrupt.
1773
Neal Norwitza12aa882006-07-06 06:45:08 +00001774- Bug #1296433: parsing XML with a non-default encoding and
1775 a CharacterDataHandler could crash the interpreter in pyexpat.
1776
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001777- Patch #1516912: improve Modules support for OpenVMS.

1783
Tim Peters32a83612006-07-10 21:08:24 +00001784- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001785 Previously, the slight difference could cause compilation errors of the
1786 'zlib' module on systems with more than one version of zlib.
1787
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001788- The MSI compileall step was fixed to also support a TARGETDIR

1819Core and builtins
1820-----------------
1821
Georg Brandla56b9152006-06-19 06:35:54 +00001822- Patch #1507676: Error messages returned by invalid abstract object operations
1823 (such as iterating over an integer) have been improved and now include the
1824 type of the offending object to help with debugging.
1825
Brett Cannonea3912b2006-06-13 21:46:41 +00001826- Bug #992017: A classic class that defined a __coerce__() method that returned
1827 its arguments swapped would infinitely recurse and segfault the interpreter.
1828
Neal Norwitz909eb122006-06-12 02:13:21 +00001829- Fix the socket tests so they can be run concurrently.
1830
Neal Norwitzb9845e72006-06-12 02:11:18 +00001831- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001832 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001833
Brett Cannon22565aa2006-06-09 22:31:23 +00001834- Bug #532646: object.__call__() will continue looking for the __call__
1835 attribute on objects until one without one is found. This leads to recursion
1836 when you take a class and set its __call__ attribute to an instance of the
1837 class. Originally fixed for classic classes, but this fix is for new-style.
1838 Removes the infinite_rec_3 crasher.
1839
Georg Brandl24250812006-06-09 18:45:48 +00001840- The string and unicode methods startswith() and endswith() now accept
1841 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1842
Brett Cannonde3b0522006-06-08 17:00:45 +00001843- Buffer objects, at the C level, never used the char buffer
1844 implementation even when the char buffer for the wrapped object was
1845 explicitly requested (originally returned the read or write buffer).
1846 Now a TypeError is raised if the char buffer is not present but is
1847 requested.
1848
Georg Brandlddbaa662006-06-04 21:56:52 +00001849- Patch #1346214: Statements like "if 0: suite" are now again optimized
1850 away like they were in Python 2.4.
1851
Georg Brandlb7c8f542006-05-27 12:30:25 +00001852- Builtin exceptions are now full-blown new-style classes instead of
1853 instances pretending to be classes, which speeds up exception handling
1854 by about 80% in comparison to 2.5a2.
1855
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001856- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1857 Unicode 4.1.
1858
Georg Brandlf4ef1162006-05-26 18:03:31 +00001859- Patch #921466: sys.path_importer_cache is now used to cache valid and
1860 invalid file paths for the built-in import machinery which leads to
1861 fewer open calls on startup.
1862
Tim Peters696cf432006-05-24 21:10:40 +00001863- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1864 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1865 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1866 the number of input digits (it was and remains linear-time for bases
1867 2, 4, 8, 16 and 32).
1868
Tim Petersb713ec22006-05-23 18:45:30 +00001869- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1870 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1871 an integer close to ``sys.maxint``. This was repaired by patch
1872 #1335972, which also gives a nice speedup.
1873
Richard Jonescebbefc2006-05-23 18:28:17 +00001874- Patch #1337051: reduced size of frame objects.
1875
1876- PyErr_NewException now accepts a tuple of base classes as its
1877 "base" parameter.
1878
Richard Jones7c88dcc2006-05-23 10:37:38 +00001879- Patch #876206: function call speedup by retaining allocated frame
1880 objects.
1881
Georg Brandl7b90e162006-05-18 07:01:27 +00001882- Bug #1462152: file() now checks more thoroughly for invalid mode
1883 strings and removes a possible "U" before passing the mode to the
1884 C library function.
1885
Neal Norwitz1004a532006-05-15 07:17:23 +00001886- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1887
Neal Norwitz373f0a72006-05-15 07:04:36 +00001888- Bug #1487966: Fix SystemError with conditional expression in assignment
1889
Martin v. Löwis879768d2006-05-11 13:28:43 +00001890- WindowsError now has two error code attributes: errno, which carries
1891 the error values from errno.h, and winerror, which carries the error
1892 values from winerror.h. Previous versions put the winerror.h values
1893 (from GetLastError()) into the errno attribute.
1894
Martin v. Löwis77736712006-05-04 05:51:03 +00001895- Patch #1475845: Raise IndentationError for unexpected indent.
1896
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001897- Patch #1479181: split open() and file() from being aliases for each other.
1898
Tim Peters44bd9862006-06-01 13:49:23 +00001899- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1900 methods were always silently ignored by dictionaries when comparing keys.
1901 They are now passed through (except when using the C API function
1902 ``PyDict_GetItem()``, whose semantics did not change).
1903
1904- Bug #1456209: In some obscure cases it was possible for a class with a
1905 custom ``__eq__()`` method to confuse dict internals when class instances
1906 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1907 No, you don't have any code that did this ;-)

1915
Brett Cannon6ee7d012006-06-08 16:23:04 +00001916- Change binascii.hexlify to accept a read-only buffer instead of only a char
1917 buffer and actually follow its documentation.
1918
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001919- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1920
Nick Coghlanc649ec52006-05-29 12:43:05 +00001921- Patch #1478788 (modified version): The functional extension module has
1922 been renamed to _functools and a functools Python wrapper module added.
1923 This provides a home for additional function related utilities that are
1924 not specifically about functional programming. See PEP 309.
1925
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001926- Patch #1493701: performance enhancements for struct module.

Georg Brandl8d3342b2006-05-16 07:38:27 +00001930- Patch #1435422: zlib's compress and decompress objects now have a
1931 copy() method.
1932
Andrew MacIntyre92913322006-06-13 15:04:24 +00001933- Patch #1454481: thread stack size is now tunable at runtime for thread
1934 enabled builds on Windows and systems with Posix threads support.
1935
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001936- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1937 (up to the system limit of 32K characters).
1938
1939- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1940 As a result, these functions now raise WindowsError instead of OSError.
1941
Tim Peters7a822da2006-05-25 21:50:17 +00001942- ``time.clock()`` on Win64 should use the high-performance Windows
1943 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1944 Windows platforms).
1945
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001946- Calling Tk_Init twice is refused if the first call failed as that
1947 may deadlock.
1948
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001949- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1950 accept it without potentially using an uninitialized pointer.
1951
1952- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1953 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1960 parameter is supplied. [SF pybsddb bug #1477863]
1961
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001962- bsddb: the __len__ method of a DB object has been fixed to return correct
1963 results. It could previously incorrectly return 0 in some cases.
1964 Fixes SF bug 1493322 (pybsddb bug 1184012).
1965
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001966- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1967 aborts the db transaction safely when a modifier callback fails.
1968 Fixes SF python patch/bug #1408584.
1969
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001970- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001971 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001972 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1973 database calls that would previously deadlock. [SF python bug #775414]

2003 double-byte encodings.
2004
Tim Peters43898b42006-06-14 04:09:25 +00002005- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2006 guarantee that adjacent triples in the return list always describe
2007 non-adjacent blocks. Previously, a pair of matching blocks could end
2008 up being described by multiple adjacent triples that formed a partition
2009 of the matching pair.
2010
Greg Ward0e0c9f42006-06-11 16:24:11 +00002011- Bug #1498146: fix optparse to handle Unicode strings in option help,

Nick Coghlan676725d2006-06-08 13:54:49 +00002021- The functions update_wrapper() and wraps() have been added to the functools
2022 module. These make it easier to copy relevant metadata from the original
2023 function when writing wrapper functions.
2024
Tim Petersd6a9eef2006-06-05 01:48:21 +00002025- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2026 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002027
Martin v. Löwis3f767792006-06-04 19:36:28 +00002028- Patch #1359618: Speed up charmap encoder by using a trie structure
2029 for lookup.
2030
Tim Petersd609b1a2006-06-02 23:22:51 +00002031- The functions in the ``pprint`` module now sort dictionaries by key
2032 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2033 if and only if its display required more than one line, although that
2034 wasn't documented. The new behavior increases predictability; e.g.,
2035 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2036
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002037- Patch #1497027: try HTTP digest auth before basic auth in urllib2
2038 (thanks for J. J. Lee).
2039
Georg Brandl2b330372006-05-28 20:23:12 +00002040- Patch #1496206: improve urllib2 handling of passwords with respect to
2041 default HTTP and HTTPS ports.
2042
George Yoshidaf3c65de2006-05-28 16:39:09 +00002043- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
2044
Bob Ippolito7298f272006-05-23 18:43:47 +00002045- Patch #1281707: speed up gzip.readline.
2046
Georg Brandlb89316f2006-05-17 15:51:16 +00002047- Patch #1180296: Two new functions were added to the locale module:
2048 format_string() to get the effect of "format % items" but locale-aware,
2049 and currency() to format a monetary number with currency sign.
2050
Georg Brandle3a25832006-05-17 14:56:04 +00002051- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2052 and several features added, such as speed and geometry control.
2053
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002054- Patch #1488881: add support for external file objects in bz2 compressed
2055 tarfiles.
2056
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002057- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2058 stdout arguments, making it possible to redirect input and output
2059 for remote debugging.
2060
2061- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2062 a couple of issues, notably handling of long file names using the
2063 GNU LONGNAME extension.
2064
2065- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2066 new flag when ``name`` is already the name of an option flag.
2067
2068- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2069 package.
2070
2071- Patch #1472854: make the rlcompleter.Completer class usable on non-
2072 UNIX platforms.
2073
2074- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
2075
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00002076- Bug #1472827: correctly escape newlines and tabs in attribute values in
2077 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002107What's New in Python 2.5 alpha 2?
2108=================================
2109
2110*Release date: 27-APR-2006*
2111
2112Core and builtins
2113-----------------
2114
Thomas Heller1b046642006-04-18 18:51:06 +00002115- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2116 by converting these apis from macros into exported functions again:
2117
2118 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2119 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2120 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2121 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2122 PyRun_String Py_CompileString
2123
Martin v. Löwis45294a92006-04-18 06:24:08 +00002124- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2125
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002126- All uses of PyStructSequence_InitType have been changed to initialize
2127 the type objects only once, even if the interpreter is initialized
2128 multiple times.
2129
Neal Norwitz61546162006-04-14 05:20:28 +00002130- Bug #1454485, array.array('u') could crash the interpreter. This was
2131 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2132 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2133
2134- Py_UNICODE is unsigned. It was always documented as unsigned, but
2135 due to a bug had a signed value in previous versions.
2136
Tim Peters3a5e8b12006-04-11 01:44:07 +00002137- Patch #837242: ``id()`` of any Python object always gives a positive
2138 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2139 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002140 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002141 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002142
Tim Peters3a5e8b12006-04-11 01:44:07 +00002143 def __hash__(self):
2144 return id(self) # WRONG
2145
2146 because a hash result must be a (short) Python int but it was always
2147 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002148 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002149 was always usable as a hash value before this patch. That's no longer
2150 necessarily so.
2151
2152- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002153 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002154 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002155 #1454844)
2156
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002157- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2158 involving generators that have paused outside of any ``try`` or ``with``
2159 blocks. (In 2.5a1, a paused generator that was part of a reference
2160 cycle could not be garbage collected, regardless of whether it was
2161 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00002162
Anthony Baxter51bcb682006-04-05 14:51:42 +00002163Extension Modules

2165
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00002166- Patch #1191065: Fix preprocessor problems on systems where recvfrom
2167 is a macro.
2168
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002169- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2170 fails with an error condition.
2171
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002172- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2173
2174- Bug #1117761: bsddb.*open() no longer raises an exception when using
2175 the cachesize parameter.
2176
2177- Bug #1149413: bsddb.*open() no longer raises an exception when using
2178 a temporary db (file=None) with the 'n' flag to truncate on open.
2179
2180- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2181 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002182
Armin Rigoa9017c32006-04-19 11:50:27 +00002183- Patch #1062014: AF_UNIX sockets under Linux have a special
2184 abstract namespace that is now fully supported.

2187-------
2188
Peter Astrand7d1d4362006-07-14 14:04:45 +00002189- Bug #1223937: subprocess.CalledProcessError reports the exit status
2190 of the process using the returncode attribute, instead of
2191 abusing errno.
2192
Tim Peters711bf302006-04-25 03:31:36 +00002193- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2194 a doctest to be skipped (the code is not run, and the expected output
2195 or exception is ignored).
2196
Nick Coghlanda2268f2006-04-24 04:37:15 +00002197- Fixed contextlib.nested to cope with exceptions being raised and
2198 caught inside exit handlers.
2199
Greg Wardab05edc2006-04-23 03:47:58 +00002200- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2201 hex, octal, or binary; add ``append_const`` action; keep going if
2202 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2203 added ``epilog`` for better help generation).
2204
Tim Peters21fbd572006-04-21 21:18:10 +00002205- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2206 called from a thread spawned as a side effect of importing a module.
2207
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002208- The pydoc module now supports documenting packages contained in
2209 .zip or .egg files.
2210
2211- The pkgutil module now has several new utility functions, such
2212 as ``walk_packages()`` to support working with packages that are either
2213 in the filesystem or zip files.
2214
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002215- The mailbox module can now modify and delete messages from
2216 mailboxes, in addition to simply reading them. Thanks to Gregory
2217 K. Johnson for writing the code, and to the 2005 Google Summer of
2218 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002219
Tim Petersc7605f22006-04-17 21:12:33 +00002220- The ``__del__`` method of class ``local`` in module ``_threading_local``
2221 returned before accomplishing any of its intended cleanup.
2222
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002223- Patch #790710: Add breakpoint command lists in pdb.
2224

2228
Anthony Baxtere29002c2006-04-12 12:07:31 +00002229- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2230 Windows. Bug #1469163.
2231
Phillip J. Eby47032112006-04-11 01:07:43 +00002232- The warnings, linecache, inspect, traceback, site, and doctest modules
2233 were updated to work correctly with modules imported from zipfiles or
2234 via other PEP 302 __loader__ objects.
2235
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002236- Patch #1467770: Reduce usage of subprocess._active to processes which
2237 the application hasn't waited on.

2247-----
2248
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002249- The Makefile now has a reindent target, which runs reindent.py on
2250 the library.
2251
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002252- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis0f48d982006-04-14 14:34:26 +00002256- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2257 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002258 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002259 CXX from --with-cxx-main, see description in README.
2260
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002261- Patch #1429775: Link extension modules with the shared libpython.
2262
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002263- Fixed a libffi build problem on MIPS systems.
2264
Tim Peters8931ff12006-05-13 23:28:20 +00002265- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2266 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2267 and "%zu" for unsigned integers of type ``size_t``.
2268
Anthony Baxter51bcb682006-04-05 14:51:42 +00002269Tests
2270-----
2271
Nick Coghlanda2268f2006-04-24 04:37:15 +00002272- test_contextlib now checks contextlib.nested can cope with exceptions
2273 being raised and caught inside exit handlers.
2274
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002275- test_cmd_line now checks operation of the -m and -c command switches
2276
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002277- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2278 it separately and by hand. It also wasn't cleaning up its changes to
2279 the current Decimal context.
2280
Thomas Woutersabd08882006-04-26 15:53:30 +00002281- regrtest.py now has a -M option to run tests that test the new limits of
2282 containers, on 64-bit architectures. Running these tests is only sensible
2283 on 64-bit machines with more than two gigabytes of memory. The argument
2284 passed is the maximum amount of memory for the tests to use.

Nick Coghlanc195d8a2006-04-24 03:04:43 +00002297- PEP 343: Added Context Types section to the library reference
2298 and attempted to bring other PEP 343 related documentation into
2299 line with the implementation and/or python-dev discussions.
2300
Tim Peters8dc73d22006-04-24 02:03:16 +00002301- Bug #1337990: clarified that ``doctest`` does not support examples

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002305What's New in Python 2.5 alpha 1?
2306=================================
2307
Anthony Baxterebed3f62006-04-03 15:03:44 +00002308*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002309
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002310Core and builtins
2311-----------------
2312
Nick Coghlan43832302006-04-23 17:04:07 +00002313- PEP 338: -m command line switch now delegates to runpy.run_module

2315
Martin v. Löwisc661b882006-04-20 04:54:23 +00002316- On Windows, .DLL is not an accepted file name extension for
2317 extension modules anymore; extensions are only found if they
2318 end in .PYD.
2319
Martin v. Löwisea62d252006-04-03 10:56:49 +00002320- Bug #1421664: sys.stderr.encoding is now set to the same value as
2321 sys.stdout.encoding.
2322

Anthony Baxter262c00a2006-03-30 10:53:17 +00002327- Fixed bug #1459029 - unicode reprs were double-escaped.
2328
Hye-Shik Changd478f342006-03-23 12:32:36 +00002329- Patch #1396919: The system scope threads are reenabled on FreeBSD
2330 5.4 and later versions.
2331
Neal Norwitze98ccf62006-03-23 05:39:47 +00002332- Bug #1115379: Compiling a Unicode string with an encoding declaration
2333 now gives a SyntaxError.
2334
Georg Brandlabd1ff82006-03-18 07:59:59 +00002335- Previously, Python code had no easy way to access the contents of a
2336 cell object. Now, a ``cell_contents`` attribute has been added
2337 (closes patch #1170323).
2338
Tim Peterscf79aac2006-03-16 01:14:46 +00002339- Patch #1123430: Python's small-object allocator now returns an arena to
2340 the system ``free()`` when all memory within an arena becomes unused
2341 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2342 freed. Some applications will see a drop in virtual memory size now,
2343 especially long-running applications that, from time to time, temporarily
2344 use a large number of small objects. Note that when Python returns an
2345 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002346 platform C library will in turn return that memory to the operating system.
2347 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002348 appears to be effective at least on Microsoft C and gcc-based systems.
2349 Thanks to Evan Jones for hard work and patience.
2350
Georg Brandl533ff6f2006-03-08 18:09:27 +00002351- Patch #1434038: property() now uses the getter's docstring if there is
2352 no "doc" argument given. This makes it possible to legitimately use
2353 property() as a decorator to produce a read-only property.
2354
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002355- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2356 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2357 of requiring an int or long in slicing and a few other contexts, enabling
2358 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2359
Neal Norwitz995acdf2006-03-07 05:01:00 +00002360- Fixed various bugs reported by Coverity's Prevent tool.
2361
Brett Cannonbf364092006-03-01 04:25:17 +00002362- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2363 new exception base class, BaseException, which has a new message attribute.
2364 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2365 Raising a string exception now raises a DeprecationWarning.
2366
Thomas Woutersfb609f42006-02-28 16:37:25 +00002367- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2368 explicitly relative, using 'from .module import name' to mean 'from the same
2369 package as this module is in. Imports without dots still default to the
2370 old relative-then-absolute, unless 'from __future__ import
2371 absolute_import' is used.
2372
Brett Cannona7446e32006-02-27 23:39:10 +00002373- Properly check if 'warnings' raises an exception (usually when a filter set
2374 to "error" is triggered) when raising a warning for raising string
2375 exceptions.
2376
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002377- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002378 The name was removed from Include/code.h.
2379
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002380- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002381
Guido van Rossum1968ad32006-02-25 22:38:04 +00002382- Patch 1433928:
2383 - The copy module now "copies" function objects (as atomic objects).
2384 - dict.__getitem__ now looks for a __missing__ hook before raising
2385 KeyError.
2386
Tim Peters84ef21c2006-02-28 20:39:06 +00002387- PEP 343: with statement implemented. Needs ``from __future__ import
2388 with_statement``. Use of 'with' as a variable will generate a warning.
2389 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002390 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002391 The following objects have __context__ methods:
2392 - The built-in file type.
2393 - The thread.LockType type.
2394 - The following types defined by the threading module:
2395 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2396 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002397
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002398- Fix the encodings package codec search function to only search
2399 inside its own package. Fixes problem reported in patch #1433198.
2400
2401 Note: Codec packages should implement and register their own
2402 codec search function. PEP 100 has the details.
2403
Tim Peters9ea89d22006-06-04 03:26:02 +00002404- PEP 353: Using ``Py_ssize_t`` as the index type.
2405
2406- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2407 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2408 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2409 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2410 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002411
Neal Norwitzfc76d632006-01-10 06:03:13 +00002412- Patch #1400181, fix unicode string formatting to not use the locale.
2413 This is how string objects work. u'%f' could use , instead of .
2414 for the decimal point. Now both strings and unicode always use periods.
2415
Neal Norwitz671b9e32006-01-09 07:07:12 +00002416- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2417 configure would break checking curses.h.
2418
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002419- Bug #959576: The pwd module is now builtin. This allows Python to be
2420 built on UNIX platforms without $HOME set.
2421
Neal Norwitzc10978f2005-12-19 06:07:16 +00002422- Bug #1072182, fix some potential problems if characters are signed.
2423
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002424- Bug #889500, fix line number on SyntaxWarning for global declarations.
2425
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002426- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2427
Neal Norwitze7214a12005-12-18 05:03:17 +00002428- Support for converting hex strings to floats no longer works.
2429 This was not portable. float('0x3') now raises a ValueError.
2430
Barry Warsaw2a38a862005-12-18 01:27:35 +00002431- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002432 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002433 is now displayed in interactive prompt banner.
2434
Georg Brandlfa166682005-12-17 21:45:17 +00002435- Implementation of PEP 341 - Unification of try/except and try/finally.
2436 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002437 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002438
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002439- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2440 now encodes backslash correctly.
2441
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002442- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2443
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002444- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002445 and long longs.
2446
Neal Norwitz67715f02005-11-09 06:59:35 +00002447- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002448 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002449 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002450
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002451- Replaced most Unicode charmap codecs with new ones using the
2452 new Unicode translate string feature in the builtin charmap
2453 codec; the codecs were created from the mapping tables available
2454 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2455 encodings now include a mapping for the Apple logo)
2456
Tim Peterse3547fd2005-12-16 23:13:57 +00002457- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002458
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002459- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002460
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002461- A new AST parser implementation was completed. The abstract
2462 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002463 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002464
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002465- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002466 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2467
Neal Norwitz708e51a2005-10-03 04:48:15 +00002468- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2469
Neal Norwitz11bd1192005-10-03 00:54:56 +00002470- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2471 Provide a warning when a directory is passed on the command line.
2472
Neal Norwitz40d37812005-10-02 01:48:49 +00002473- Fix segfault with invalid coding.
2474
2475- SF bug #772896: unknown encoding results in MemoryError.
2476
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002477- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002478 supported a __len__() method which evaluated to False when the iterator
2479 was empty.
2480
Guido van Rossum630db602005-09-20 18:49:54 +00002481- On 64-bit platforms, when __len__() returns a value that cannot be
2482 represented as a C int, raise OverflowError.
2483
Skip Montanarof8948ca2005-09-19 03:54:46 +00002484- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002485 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002486
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002487- SF bug #893549: parsing keyword arguments was broken with a few format
2488 codes.
2489
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002490- Changes donated by Elemental Security to make it work on AIX 5.3
2491 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2492 bug #105470: test_pwd fails on 64bit system (Opteron).
2493
Guido van Rossum539c6622005-09-14 17:49:54 +00002494- Changes donated by Elemental Security to make it work on HP-UX 11 on
2495 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2496
Georg Brandl4550b8d2005-08-26 06:43:52 +00002497- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002498 (fixes bug #1119418).
2499
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002500- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2501
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002502- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2503 exceptions that cause a function to exit.
2504
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002505- The implementation of set() and frozenset() was revised to use its
2506 own internal data structure. Memory consumption is reduced by 1/3
2507 and there are modest speed-ups as well. The API is unchanged.
2508
Tim Petersde7990b2005-07-17 23:45:23 +00002509- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2510
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002511- SF bug #1229429: PyObject_CallMethod failed to decrement some
2512 reference counts in some error exit cases.
2513
Tim Petersecc6e6a2005-07-10 22:30:55 +00002514- SF bug #1185883: Python's small-object memory allocator took over
2515 a block managed by the platform C library whenever a realloc specified
2516 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002517 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002518 portable way to copy data from the C-managed block into Python's
2519 small-object space without risking a memory fault. Python's small-object
2520 realloc now leaves such blocks under the control of the platform C
2521 realloc.
2522
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002523- SF bug #1232517: An overflow error was not detected properly when
2524 attempting to convert a large float to an int in os.utime().
2525
Raymond Hettinger3296e692005-06-29 23:29:56 +00002526- SF bug #1224347: hex longs now print with lowercase letters just
2527 like their int counterparts.
2528
Michael W. Hudson188d4362005-06-20 16:52:57 +00002529- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2530 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2531 interpreter states; back out that fix and do a better job (see
2532 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2533 for a longer write-up of the problem).
2534
Michael W. Hudsondf888462005-06-03 14:41:55 +00002535- SF patch #1180995: marshal now uses a binary format by default when
2536 serializing floats.
2537
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002538- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2539 the routines that promise to produce IEEE 754 binary representations
2540 of floats now simply copy bytes around.
2541
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002542- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2543 278.
2544
Brett Cannonc3647ac2005-04-26 03:45:26 +00002545- patch #1109424: int, long, float, complex, and unicode now check for the
2546 proper magic slot for type conversions when subclassed. Previously the
2547 magic slot was ignored during conversion. Semantics now match the way
2548 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002549 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002550 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002551 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002552
Barry Warsawc8d907c2005-04-19 23:43:40 +00002553- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2554 NULL, now raise an AttributeError when attempting to set or delete the
2555 attribute. Previously a TypeError was raised, but this was inconsistent
2556 with the equivalent pure-Python implementation.
2557
Michael W. Hudson774479c2005-04-18 08:46:17 +00002558- It is now safe to call PyGILState_Release() before
2559 PyEval_InitThreads() (note that if there is reason to believe there
2560 are multiple threads around you still must call PyEval_InitThreads()
2561 before using the Python API; this fix is for extension modules that
2562 have no way of knowing if Python is multi-threaded yet).
2563
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002564- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2565 disabled caused a crash.
2566
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002567- Bug #1165306: instancemethod_new allowed the creation of a method
2568 with im_class == im_self == NULL, which caused a crash when called.
2569
Tim Petersecc6e6a2005-07-10 22:30:55 +00002570- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002571 fixes the crash seen in bug #1165761
2572
Raymond Hettinger96229b12005-03-11 06:49:40 +00002573- Added two new builtins, any() and all().
2574
Brett Cannon409d8f22005-03-05 06:47:57 +00002575- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002576 (e.g., ``class C(): pass`` is no longer a syntax error).
2577 Patch #1176012 added support to the 'parser' module and 'compiler' package
2578 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002579
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002580- Patch #1115086: Support PY_LONGLONG in structmember.
2581
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002582- Bug #1155938: new style classes did not check that __init__() was
2583 returning None.
2584
Tim Petersecc6e6a2005-07-10 22:30:55 +00002585- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002586 ('\') with a specific error message.
2587
Martin v. Löwisff232d72005-03-03 09:24:38 +00002588- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2589
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002590- Bug #1124295: the __name__ attribute of file objects was
2591 inadvertently made inaccessible in restricted mode.

2612 unicode instance if the argument is not an instance of basestring and
2613 calling __str__ on the argument returns a unicode instance.
2614
Tim Petersf4e69282006-02-27 17:15:31 +00002615- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2616 current thread state when the auto-GIL-state machinery knows about
2617 it (since the thread state is being deleted, continuing to remember it
2618 can't help, but can hurt if another thread happens to get created with
2619 the same thread id).

2827 in attribute values.
2828
Anthony Baxterc51ee692006-04-01 00:57:31 +00002829- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002830 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002831 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002832 module will not be built.

Tim Petersc17976e2006-04-01 00:26:53 +00002834- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2835 aren't officially supported here, and trying to use them will probably

Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002858- email 4.0 package now integrated. This is largely the same as the email 3.0
2859 package that was included in Python 2.3, except that PEP 8 module names are
2860 now used (e.g. mail.message instead of email.Message). The MIME classes
2861 have been moved to a subpackage (e.g. email.mime.text instead of
2862 email.MIMEText). The old names are still supported for now. Several
2863 deprecated Message methods have been removed and lots of bugs have been
2864 fixed. More details can be found in the email package documentation.

2867 (a subclass of tuple) that provides incremental decoders and encoders
2868 (a way to use stateful codecs without the stream API). Python functions
2869 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2870 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2871 have been added.

2874 a ValueError instead of a StopIteration now (like file and cString.String do).
2875 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2876 called before (like file and StringIO.StringIO do).

2952 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2953 Ronald L. Rivest offered this advice for Python:
2954
2955 "The consensus of researchers in this area (at least as
2956 expressed at the NIST Hash Function Workshop 10/31/05),
2957 is that SHA-256 is a good choice for the time being, but
2958 that research should continue, and other alternatives may
2959 arise from this research. The larger SHA's also seem OK."

Guido van Rossumd0641422005-02-03 15:01:24 +00003120- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3121 disables recursive traversal through instance attributes, which can
3122 be exploited in various ways.
3123
Tim Peterse3547fd2005-12-16 23:13:57 +00003124- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003125 flags on the HTTP listening socket.
3126
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003127- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3128 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3129
Fred Drakefbdeaad2006-07-29 16:56:15 +00003130- Patches #893642, #1039083: add allow_none, encoding arguments to
3131 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003132
Martin v. Löwis1d11de62005-01-29 13:29:23 +00003133- Bug #1110478: Revert os.environ.update to do putenv again.
3134
Thomas Hellerd6c6e222005-01-20 19:20:16 +00003135- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3136
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003137- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3138
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003139- Enhancements to the csv module:
3140
3141 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003142 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003143 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003144 + Dialect parameter parsing has been re-implemented to improve error
3145 reporting.
3146 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3147 dictates.
3148 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003149 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003150 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003151 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3152 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003153 + reader now allows \r characters to be quoted (previously it only allowed
3154 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003155 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003156 + Dialect classes passed to the module are no longer instantiated by
3157 the module before being parsed (the former validation scheme required
3158 this, but the mechanism was unreliable).
3159 + The dialect registry now contains instances of the internal
3160 C-coded dialect type, rather than references to python objects.
3161 + the internal c-coded dialect type is now immutable.
3162 + register_dialect now accepts the same keyword dialect specifications
3163 as the reader and writer, allowing the user to register dialects
3164 without first creating a dialect class.
3165 + a configurable limit to the size of parsed fields has been added -
3166 previously, an unmatched quote character could result in the entire
3167 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003168 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003169 the parser field size limit (returning the former limit). The initial
3170 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003171 + A line_num attribute has been added to the reader object, which tracks
3172 the number of lines read from the source iterator. This is not
3173 the same as the number of records returned, as records can span
3174 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003175 + reader and writer objects were not being registered with the cyclic-GC.
3176 This has been fixed.
3177
Brett Cannone6539c42005-01-08 02:43:53 +00003178- _DummyThread objects in the threading module now delete self.__block that is
3179 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3180 lock primitives tend to be limited in number and thus should not be wasted on
3181 a _DummyThread object. Fixes bug #1089632.
3182
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003183- The imghdr module now detects Exif files.
3184
Raymond Hettinger6065d322004-12-20 23:51:53 +00003185- StringIO.truncate() now correctly adjusts the size attribute.
3186 (Bug #951915).
3187
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003188- locale.py now uses an updated locale alias table (built using
3189 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3190 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003191 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003192
Raymond Hettinger3557f422004-12-07 12:02:02 +00003193- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3194
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003195- the pickle module no longer accepts the deprecated None option in the
3196 args tuple returned by __reduce__().
3197
Brett Cannon84667c02004-12-07 03:25:18 +00003198- optparse now optionally imports gettext. This allows its use in setup.py.
3199
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003200- the pickle module no longer uses the deprecated bin parameter.
3201
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003202- the shelve module no longer uses the deprecated binary parameter.
3203
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003204- the pstats module no longer uses the deprecated ignore() method.
3205
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003206- the filecmp module no longer uses the deprecated use_statcache argument.
3207
Raymond Hettinger664347b2004-12-04 21:21:53 +00003208- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3209 extended or overridden by subclasses. Formerly, the subclassed method would
3210 be ignored by the rest of the module. (Bug #1078905).
3211
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003212- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003213 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003214
Walter Dörwald36733692004-12-22 12:50:50 +00003215- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3216 once when a size argument is given. This prevents a buffer overflow in the
3217 tokenizer with very long source lines.
3218
Barry Warsaw538561e2006-01-01 21:48:54 +00003219- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3220 immediately after creating the object, without any intervening
3221 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003222
Skip Montanaro05885812005-01-16 20:48:27 +00003223- The reconvert.quote function can now emit triple-quoted strings. The
3224 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003225
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003226- ``UserString.MutableString`` now supports negative indices in
3227 ``__setitem__`` and ``__delitem__``
3228
Greg Ward40407942005-03-05 02:53:17 +00003229- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3230 correctly.
3231
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003232- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3233 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3234 character even if the user has passed a size parameter to get a proper
3235 line ending. Remove the special handling of a "\r\n" that has been split
3236 between two lines.
3237
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003238- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3239 about illegal code points. The codec now supports PEP 293 style error
3240 handlers.
3241
Walter Dörwald78a78b02005-09-01 12:04:29 +00003242- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003243 from the input stream, so that the output is a byte string in the correct
3244 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003245
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003246- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3247 considering it exactly like a '*'.
3248
Walter Dörwald007f8df2005-10-09 19:42:27 +00003249- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3250 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003251
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003252- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3253
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003254- Patch #1413711: Certain patterns of differences were making difflib
3255 touch the recursion limit.
3256
Walter Dörwald58917a62006-03-31 15:26:22 +00003257- Bug #947906: An object oriented interface has been added to the calendar
3258 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003259 called as a script (e.g. via ``python -mcalendar``). Localized month and
3260 weekday names can be ouput (even if an exotic encoding is used) using
3261 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003262
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003263Build
3264-----
3265
Neal Norwitz602d3392006-03-31 08:21:40 +00003266- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3267 by using -mieee gcc option.
3268

3270
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003271- Build support for Win64-AMD64 was added.
3272
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003273- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3274
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003275- Patch #881820: look for openpty and forkpty also in libbsd.
3276
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003277- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3278 The zlib module is now builtin on Windows.
3279
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003280- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3281
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003282- Bug #1189330: configure did not correctly determine the necessary
3283 value of LINKCC if python was built with GCC 4.0.
3284
Trent Mick8321b422005-07-26 02:29:21 +00003285- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3286 vulnerability in zlib 1.2.1 and 1.2.2.
3287
Brett Cannon08cd5982005-04-24 22:26:38 +00003288- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3289 flags that change binary compatibility. Changes were also made to
3290 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003291 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003292
Bob Ippolitoed233462005-03-29 13:47:59 +00003293- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3294 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3295 no longer exists). This configure patch makes things right.
3296
Martin v. Löwise2713be2005-03-08 15:03:08 +00003297- Bug #1158607: Build with --disable-unicode again.
3298
Brett Cannon46d96232005-02-16 00:07:19 +00003299- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3300 defined. Discovered as a result of not being able to build on OS X.
3301
Brett Cannon516592f2004-12-07 00:42:59 +00003302- setup.py now uses the directories specified in LDFLAGS using the -L option
3303 and in CPPFLAGS using the -I option for adding library and include
3304 directories, respectively, for compiling extension modules against. This has
3305 led to the core being compiled using the values in CPPFLAGS. It also removes
3306 the need for the special-casing of both DarwinPorts and Fink for darwin since
3307 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3308 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3309 Fink, ``-I/opt/local/include`` for DarwinPorts).
3310
Brett Cannon43802422005-02-10 20:48:03 +00003311- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3312 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3313 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3314 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003316C API
3317-----
3318
Tim Petersc9d78aa2006-03-26 23:27:58 +00003319- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3320 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3321 is obtained via the ``PyObject_`` family, it must be released via the
3322 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3323 always been officially true, but when Python's small-object allocator was
3324 introduced, an attempt was made to cater to a few extension modules
3325 discovered at the time that obtained memory via ``PyObject_New`` but
3326 released it via ``PyMem_DEL``. It's years later, and if such code still
3327 exists it will fail now (probably with segfaults, but calling wrong
3328 low-level memory management functions can yield many symptoms).
3329
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003330- Added a C API for set and frozenset objects.
3331
Raymond Hettinger66517482004-12-03 11:45:13 +00003332- Removed PyRange_New().
3333
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003334- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3335 mapping argument now. This string is used as a mapping table. Byte values
3336 greater than the length of the string and 0xFFFE are treated as undefined
3337 mappings.
