19
Jeffrey Yasskin478a1aa2008-12-10 07:28:12 +000020- Issue #4589: Propagated an exception thrown by a context manager's

26
Benjamin Peterson6f08e852008-11-03 15:19:35 +000027- Issue #4048: The parser module now correctly validates relative imports.
28
Amaury Forgeot d'Arc3b335ff2008-10-30 21:40:05 +000029- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
30 method does not return iterators for the 4th and 5th items.
31
Amaury Forgeot d'Arcb50f9922008-09-26 22:46:01 +000032- Issue #3967: Fixed a crash in the count() and find() methods of string-like
33 objects, when the "start" parameter is a huge value.
34
Benjamin Petersond1c7d072008-09-25 20:46:05 +000035- Issue #3936: The parser warnings for using "as" and "with" as variable names
36 didn't fire after import statements.

43
Neal Norwitz4f3be8a2008-07-31 17:08:14 +000044- Apply security patches from Apple.
45
Neal Norwitz83ac0142008-07-28 05:06:20 +000046- Issue #2620: Overflow checking when allocating or reallocating memory
47 was not always being done properly in some python types and extension
48 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
49 all been updated to perform better checks and places in the code that
50 would previously leak memory on the error path when such an allocation
51 failed have been fixed.
52
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +000053- Issue #2242: Fix a crash when decoding invalid utf-7 input on certain

Amaury Forgeot d'Arcceda6a62008-07-01 20:52:56 +000059- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
60 set to a custom object whose write() method happens to install
61 another file in sys.stdout.
62
Amaury Forgeot d'Arcb15bdf72008-07-01 20:59:49 +000063- Issue #3088: Corrected a race condition in classes derived from
64 threading.local: the first member set by a thread could be saved in
65 another thread's dictionary.
66
Amaury Forgeot d'Arc3255e132008-06-16 19:22:42 +000067- Issue #3100: Corrected a crash on deallocation of a subclassed weakref which
68 holds the last (strong) reference to its referent.
69
Guido van Rossumaa975432008-04-10 22:43:58 +000070- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
71 having a self-referential tuple, which is possible from C code. Nor did
72 object's tp_str consider that a type's tp_str could do something that could
73 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
74 respectively, fixed the issues. (Backport of r58288 from trunk.)
75
Georg Brandld9f1da02008-03-29 01:50:46 +000076- Patch #1442: properly report exceptions when the PYTHONSTARTUP file

80 reference on the outer class name.
81
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000082- Issue #1477: With narrow Unicode builds, the unicode escape sequence
83 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
84 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
85 UTF-16 surrogates are generated in this case, like normal unicode literals
86 and the 'unicode-escape' codec.
87
Neal Norwitzb3635f92008-03-18 04:17:36 +000088- Issue #2321: use pymalloc for unicode object string data to reduce
89 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +000090
Sean Reifscheider4af861c2008-03-20 17:39:31 +000091- Issue #2238: Some syntax errors in *args and **kwargs expressions could give
92 bogus error messages.
93
Gregory P. Smith14acde32008-04-09 23:41:13 +000094- Issue #2587: In the C API, PyString_FromStringAndSize() takes a signed size
95 parameter but was not verifying that it was greater than zero. Values
96 less than zero will now raise a SystemError and return NULL to indicate a
97 bug in the calling C code.
98
Gregory P. Smith9aa040d2008-06-02 00:07:25 +000099- Issue #2588, #2589: Fix potential integer underflow and overflow
100 conditions in the PyOS_vsnprintf C API function.
101
Gregory P. Smithcae7f882008-09-07 06:44:12 +0000102- Issue #1204: The configure script now tests for additional libraries
103 that may be required when linking against readline. This fixes issues
104 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
Georg Brandld9f1da02008-03-29 01:50:46 +0000105
Gregory P. Smitha7a94a02008-09-22 00:22:44 +0000106- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
107 library targets in the Makefile.

Amaury Forgeot d'Arc22679b82008-08-18 19:33:42 +0000145- Issue #2234: distutils failed for some versions of the cygwin compiler. The
146 version reported by these tools does not necessarily follow the python
147 version numbering scheme, so the module is less strict when parsing it.
148
Hirokazu Yamamoto1d63a452008-08-17 09:49:10 +0000149- Issue #2222: Fixed reference leak when occured os.rename()

305-----------------
306

308 only available if asserts are left in the code, in cases where they
309 can't be triggered from Python code.
310

312 collections.defaultdict, if its default_factory is set to a bound method.
313
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000314- Issue #1920: "while 0" statements were completely removed by the compiler,
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000315 even in the presence of an "else" clause, which is supposed to be run when
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000316 the condition is false. Now the compiler correctly emits bytecode for the
317 "else" suite.
318

321 borrowed_ref_[34].py (not in tracker).
322
323- Fix for #1303614 and #1174712 backported from the trunk:
324 __dict__ descriptor abuse for subclasses of built-in types;
325 subclassing from both ModuleType and another built-in types.
326

329 support.
330

332 folding optimization. This was a regression from Python 2.4.
333
Georg Brandl78d50cc2008-01-21 18:36:54 +0000334- Issue #1882: when compiling code from a string, encoding cookies in the

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

Neal Norwitz3b3aae02006-09-05 03:56:01 +00001159- Bug #1520864: unpacking singleton tuples in list comprehensions and
1160 generator expressions (x for x, in ... ) works again. Fixing this problem
1161 required changing the .pyc magic number. This means that .pyc files
1162 generated before 2.5c2 will be regenerated.

1274Core and builtins
1275-----------------
1276
Neal Norwitz24b6f202006-09-05 04:43:56 +00001277- Fix infinite recursion when subclassing long and overriding __hash__.
1278
1279- Fix concatenation (+=) of long strings.
1280
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001281- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001282 compared equal or unequal to a string and a UnicodeDecodeError
1283 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001284
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001285 Instead, the equal (==) and unequal (!=) comparison operators will
1286 now issue a UnicodeWarning and interpret the two objects as
1287 unequal. The UnicodeWarning can be filtered as desired using
1288 the warning framework, e.g. silenced completely, turned into an
1289 exception, logged, etc.
1290
1291 Note that compare operators other than equal and unequal will still
1292 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001293
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001294- Fix segfault when doing string formatting on subclasses of long.
1295
1296- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1297 with new-style classes.
1298
1299- Fix bug related to __len__ functions returning negative values with
1300 classic classes.
1301
1302- Patch #1538606, Fix __index__() clipping. There were some problems
1303 discovered with the API and how integers that didn't fit into Py_ssize_t
1304 were handled. This patch attempts to provide enough alternatives
1305 to effectively use __index__.
1306
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001307- Bug #1536021: __hash__ may now return long int; the final hash
1308 value is obtained by invoking hash on the long int.
1309
Thomas Hellerab1049c2006-08-08 17:37:00 +00001310- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1311
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001312- Bug #1535165: fixed a segfault in input() and raw_input() when
1313 sys.stdin is closed.
1314
Thomas Heller74d36f02006-08-04 18:17:40 +00001315- On Windows, the PyErr_Warn function is now exported from
1316 the Python dll again.
1317
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001318- Bug #1191458: tracing over for loops now produces a line event
1319 on each iteration. Fixing this problem required changing the .pyc
1320 magic number. This means that .pyc files generated before 2.5c1
1321 will be regenerated.
1322
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001323- Bug #1333982: string/number constants were inappropriately stored
1324 in the byte code and co_consts even if they were not used, ie
1325 immediately popped off the stack.
1326
Georg Brandle9462c72006-08-04 18:03:37 +00001327- Fixed a reference-counting problem in property().

1330Library
1331-------
1332
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001333- Fix a bug in the ``compiler`` package that caused invalid code to be
1334 generated for generator expressions.
1335
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001336- The distutils version has been changed to 2.5.0. The change to
1337 keep it programmatically in sync with the Python version running
1338 the code (introduced in 2.5b3) has been reverted. It will continue
1339 to be maintained manually as static string literal.
1340
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001341- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001342 and this cannot be converted to the required C type, an exception is
1343 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001344 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001345
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001346- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001347 an exception.
1348
Tim Peterscbdd3502006-09-05 01:47:53 +00001349- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001350 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001351 workarounds for clocks with low resolution, to stop the code yielding
1352 duplicate UUIDs.
1353
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001354- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1355 before raising SystemExit, allowing IDLE to honor quit() and exit().
1356
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001357- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1358
Georg Brandl7a1af772006-08-14 21:55:28 +00001359- Patch #1536071: trace.py should now find the full module name of a
1360 file correctly even on Windows.
1361
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001362- logging's atexit hook now runs even if the rest of the module has
1363 already been cleaned up.
1364
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001365- Bug #1112549, fix DoS attack on cgi.FieldStorage.

1368 str(exception) raised an exception.
1369
Neil Schemenauer06ded092006-08-04 16:20:30 +00001370- Fix a bug in the ``compiler`` package that caused invalid code to be

1388 uses the _as_parameter_ attribute when objects are passed to foreign
1389 function calls. The ctypes version number was changed to 1.0.1.
1390
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001391- Bug #1530559, struct.pack raises TypeError where it used to convert.

Neal Norwitz07aadb12006-07-30 06:55:48 +00001451- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1452 This provides the proper warning for struct.pack().
1453 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1454
Neal Norwitz0d62a062006-07-30 06:53:31 +00001455- Patch #1531113: Fix augmented assignment with yield expressions.
1456 Also fix a SystemError when trying to assign to yield expressions.
1457
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001458- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1459 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1460 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1461 excessive filesystem operations during imports.
1462
Tim Petersbc24eee2006-07-27 01:14:53 +00001463- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1464 operations on signed longs that are formally undefined by C.
1465 Unfortunately, at least one compiler now cares about that, so complicated
1466 the code to make that compiler happy again.
1467
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001468- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1469
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001470- Patch #1232023: Stop including current directory in search
1471 path on Windows.
1472
Neal Norwitze1fdb322006-07-21 05:32:28 +00001473- Fix some potential crashes found with failmalloc.
1474
Neal Norwitze7563102006-07-17 01:00:16 +00001475- Fix warnings reported by Klocwork's static analysis tool.
1476
Neal Norwitz84be93b2006-07-16 01:50:38 +00001477- Bug #1512814, Fix incorrect lineno's when code within a function
1478 had more than 255 blank lines.
1479
Georg Brandl9dceedb2006-07-12 15:31:17 +00001480- Patch #1521179: Python now accepts the standard options ``--help`` and
1481 ``--version`` as well as ``/?`` on Windows.
1482
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001483- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001484 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001485 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001486
Tim Peters112aad32006-07-19 00:03:19 +00001487- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001488 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001489 new ``sys._current_frames()`` returns a dictionary with one entry,
1490 mapping the faux "thread id" 0 to the current frame.
1491
Ronald Oussoren3075e162006-07-25 20:28:55 +00001492- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001493

1496-------
1497
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001498- Correction of patch #1455898: In the mbcs decoder, set final=False
1499 for stream decoder, but final=True for the decode function.
1500
Georg Brandl07fec3a2006-08-01 18:49:24 +00001501- os.urandom no longer masks unrelated exceptions like SystemExit or
1502 KeyboardInterrupt.
1503
Tim Peters4643c2f2006-08-10 22:45:34 +00001504- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001505 shutil.copytree on Windows
1506
Georg Brandle34ac7c2006-07-30 11:07:23 +00001507- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1508 refers to file descriptors, not file objects.
1509
Tim Peterscbdd3502006-09-05 01:47:53 +00001510- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001511 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001512 #1513611, and probably others.
1513
Georg Brandledd9b0d2006-07-29 09:33:26 +00001514- Bug #1441397: The compiler module now recognizes module and function
1515 docstrings correctly as it did in Python 2.4.
1516
Tim Peters6f681472006-07-27 23:44:37 +00001517- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1518 lost that tests are sorted by name before being run. This rarely
1519 matters for well-written tests, but can create baffling symptoms if
1520 side effects from one test to the next affect outcomes. ``DocTestFinder``
1521 has been changed to sort the list of tests it returns.
1522
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001523- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001524 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001525
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001526- Bug #978833: Really close underlying socket in _socketobject.close.
1527
Georg Brandldb232dc2006-08-20 13:15:43 +00001528- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1529 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001530
Georg Brandlcf0c1722006-07-26 07:23:32 +00001531- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1532 to recursive calls and call it with the failing package name.
1533
Martin v. Löwis0b483032006-07-25 09:53:12 +00001534- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1535
Georg Brandlc13c34c2006-07-24 14:09:56 +00001536- Patch #1515343: Fix printing of deprecated string exceptions with a
1537 value in the traceback module.
1538
Greg Ward48fae7a2006-07-23 16:05:51 +00001539- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1540
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001541- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1542
Brett Cannoncaebe222006-07-18 04:41:36 +00001543- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1544 argument tuple. For arguments where zero is illegal, the value is forced to
1545 the minimum value that is correct. This is to support an undocumented but
1546 common way people used to fill in inconsequential information in the time
1547 tuple pre-2.4.
1548
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001549- Patch #1220874: Update the binhex module for Mach-O.
1550
Barry Warsawb110bad2006-07-21 14:51:07 +00001551- The email package has improved RFC 2231 support, specifically for
1552 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1553 (name*0=<blah>) parameter continuations. This may change the types of
1554 values returned from email.message.Message.get_param() and friends.
1555 Specifically in some cases where non-encoded continuations were used,
1556 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1557 will just return the string (since non-encoded continuations don't have
1558 charset and language parts).
1559
1560 Also, whereas % values were decoded in all parameter continuations, they are
1561 now only decoded in encoded parameter parts.
1562
Ronald Oussoren3075e162006-07-25 20:28:55 +00001563- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1564
1565- Bug #1517996: IDLE now longer shows the default Tk menu when a
1566 path browser, class browser or debugger is the frontmost window on MacOS X
1567
Barry Warsaw00decd72006-07-27 23:43:15 +00001568- Patch #1520294: Support for getset and member descriptors in types.py,
1569 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1570 of an object against these built-in types and more importantly, for getting
1571 their docstrings printed in the interactive interpreter's help() function.

1575-----------------
1576
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001577- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1578 a socket operation on a socket with a timeout, the exception will be
1579 caught correctly. Previously, the exception was not caught.
1580
Thomas Heller1393d6a2006-07-28 21:43:20 +00001581- Patch #1529514: The _ctypes extension is now compiled on more
1582 openbsd target platforms.
1583
Tim Peters9cab5932006-07-28 00:30:00 +00001584- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1585 a memory leak, affecting pickles and deep copies.
1586
Tim Petersbc24eee2006-07-27 01:14:53 +00001587- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001588 Paul Eggert.
1589
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001590- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1591
Thomas Hellerce049a02006-07-14 17:51:14 +00001592- Patch #1521817: Index range checking on ctypes arrays containing
1593 exactly one element enabled again. This allows iterating over these
1594 arrays, without the need to check the array size before.
1595
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001596- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001597 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001598 /dev/null in certain cases; this is now fixed.
1599
Thomas Heller47d7a062006-07-12 08:43:47 +00001600- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1601 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001602
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001603- Because of a misspelled preprocessor symbol, ctypes was always
1604 compiled without thread support; this is now fixed.
1605
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001606- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1607 methods now allow their database parameter to be None as the
1608 sleepycat API allows.
1609
Matt Flemingec926502006-07-28 11:27:27 +00001610- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1611 bluetooth API compared with Linux and FreeBSD.
1612
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001613Tests
1614-----
1615
1616- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1617 how long the test file should take to play. Now accepts taking 2.93 secs
1618 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1619
Georg Brandl4793aa32006-07-28 18:31:39 +00001620- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1621 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1622 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001629Mac
1630---
1631
1632- PythonLauncher now works correctly when the path to the script contains
1633 characters that are treated specially by the shell (such as quotes).
1634
1635- Bug #1527397: PythonLauncher now launches scripts with the working directory
1636 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001637 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001638 expect.

1647-----------------
1648
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001649- Bug #1441486: The literal representation of -(sys.maxint - 1)
1650 again evaluates to a int object, not a long.
1651
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001652- Bug #1501934: The scope of global variables that are locally assigned
1653 using augmented assignment is now correctly determined.
1654
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001655- Bug #927248: Recursive method-wrapper objects can now safely
1656 be released.
1657
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001658- Bug #1417699: Reject locale-specific decimal point in float()
1659 and atof().
1660
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001661- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1662 omit a default "error" argument for NULL pointer. This allows
1663 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001664
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001665- Bug #1519018: 'as' is now validated properly in import statements.
1666
Neal Norwitz28746ab2006-07-09 22:14:42 +00001667- On 64 bit systems, int literals that use less than 64 bits are
1668 now ints rather than longs.
1669
Neal Norwitzed657552006-07-10 00:04:44 +00001670- Bug #1512814, Fix incorrect lineno's when code at module scope
1671 started after line 256.
1672
Tim Peters32a83612006-07-10 21:08:24 +00001673- New function ``sys._current_frames()`` returns a dict mapping thread
1674 id to topmost thread stack frame. This is for expert use, and is
1675 especially useful for debugging application deadlocks. The functionality
1676 was previously available in Fazal Majid's ``threadframe`` extension
1677 module, but it wasn't possible to do this in a wholly threadsafe way from
1678 an extension.

Martin v. Löwis77621582006-07-30 13:27:31 +00001683- Bug #1257728: Mention Cygwin in distutils error message about a missing
1684 VS 2003.
1685
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001686- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1687
Tim Peters32a83612006-07-10 21:08:24 +00001688- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001689 environment variable to be set in order to the SDK environment
1690 for finding the compiler, include files, etc.

Martin v. Löwis388a8c22006-07-06 19:28:03 +00001692- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1693
Nick Coghlan2d792252006-07-06 13:47:18 +00001694- warnings.py now ignores ImportWarning by default
1695
Thomas Woutersadd19112006-07-05 11:03:49 +00001696- string.Template() now correctly handles tuple-values. Previously,
1697 multi-value tuples would raise an exception and single-value tuples would
1698 be treated as the value they contain, instead.
1699
Martin v. Löwisede77f52006-07-03 13:01:35 +00001700- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1701 even if some data are received.
1702
Martin v. Löwis45482392006-07-03 12:28:58 +00001703- Bug #1267547: Put proper recursive setup.py call into the
1704 spec file generated by bdist_rpm.
1705
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001706- Bug #1514693: Update turtle's heading when switching between
1707 degrees and radians.
1708
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001709- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001710 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001711
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001712- Bug #1514703: Only setup canvas window in turtle when the canvas
1713 is created.
1714
Martin v. Löwis7596e832006-07-01 15:33:37 +00001715- Bug #1513223: .close() of a _socketobj now releases the underlying
1716 socket again, which then gets closed as it becomes unreferenced.
1717
Fred Drake10497c82006-06-29 02:57:48 +00001718- Bug #1504333: Make sgmllib support angle brackets in quoted
1719 attribute values.
1720
1721- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1722 sgmllib ('[' and ']' were not accepted).
1723
Georg Brandl1be63af2006-06-28 20:23:25 +00001724- Fix a bug in the turtle module's end_fill function.
1725
Brett Cannon53ab5b72006-06-22 16:49:14 +00001726- Bug #1510580: The 'warnings' module improperly required that a Warning
1727 category be either a types.ClassType and a subclass of Warning. The proper
1728 check is just that it is a subclass with Warning as the documentation states.
1729
Georg Brandlad29e632006-06-21 17:45:17 +00001730- The compiler module now correctly compiles the new try-except-finally
1731 statement (bug #1509132).
1732
Neal Norwitz60373cd2006-06-22 06:30:50 +00001733- The wsgiref package is now installed properly on Unix.
1734
Vinay Sajip28e57612006-07-01 10:45:20 +00001735- A bug was fixed in logging.config.fileConfig() which caused a crash on
1736 shutdown when fileConfig() was called multiple times.
1737
Gerhard Häring762fbd32006-07-02 17:48:30 +00001738- The sqlite3 module did cut off data from the SQLite database at the first
1739 null character before sending it to a custom converter. This has been fixed
1740 now.

1743-----------------
1744
Tim Peters112aad32006-07-19 00:03:19 +00001745- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1746 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1747 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001748
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001749- Assigning None to pointer type fields in ctypes structures possible
1750 overwrote the wrong fields, this is fixed now.
1751
1752- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1753 on non-Windows platforms.
1754
1755- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1756 integer or long, without range checking.
1757
1758- Patch #1517790: It is now possible to use custom objects in the ctypes
1759 foreign function argtypes sequence as long as they provide a from_param
1760 method, no longer is it required that the object is a ctypes type.
1761
1762- The '_ctypes' extension module now works when Python is configured
1763 with the --without-threads option.
1764
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001765- Bug #1513646: os.access on Windows now correctly determines write
1766 access, again.
1767
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001768- Bug #1512695: cPickle.loads could crash if it was interrupted with
1769 a KeyboardInterrupt.
1770
Neal Norwitza12aa882006-07-06 06:45:08 +00001771- Bug #1296433: parsing XML with a non-default encoding and
1772 a CharacterDataHandler could crash the interpreter in pyexpat.
1773
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001774- Patch #1516912: improve Modules support for OpenVMS.

Martin v. Löwisd73168d2006-07-14 09:58:55 +00001779- Automate Windows build process for the Win64 SSL module.
1780
Tim Peters32a83612006-07-10 21:08:24 +00001781- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001782 Previously, the slight difference could cause compilation errors of the
1783 'zlib' module on systems with more than one version of zlib.
1784
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001785- The MSI compileall step was fixed to also support a TARGETDIR

1816Core and builtins
1817-----------------
1818
Georg Brandla56b9152006-06-19 06:35:54 +00001819- Patch #1507676: Error messages returned by invalid abstract object operations
1820 (such as iterating over an integer) have been improved and now include the
1821 type of the offending object to help with debugging.
1822
Brett Cannonea3912b2006-06-13 21:46:41 +00001823- Bug #992017: A classic class that defined a __coerce__() method that returned
1824 its arguments swapped would infinitely recurse and segfault the interpreter.
1825
Neal Norwitz909eb122006-06-12 02:13:21 +00001826- Fix the socket tests so they can be run concurrently.
1827
Neal Norwitzb9845e72006-06-12 02:11:18 +00001828- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001829 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001830
Brett Cannon22565aa2006-06-09 22:31:23 +00001831- Bug #532646: object.__call__() will continue looking for the __call__
1832 attribute on objects until one without one is found. This leads to recursion
1833 when you take a class and set its __call__ attribute to an instance of the
1834 class. Originally fixed for classic classes, but this fix is for new-style.
1835 Removes the infinite_rec_3 crasher.
1836
Georg Brandl24250812006-06-09 18:45:48 +00001837- The string and unicode methods startswith() and endswith() now accept
1838 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1839
Brett Cannonde3b0522006-06-08 17:00:45 +00001840- Buffer objects, at the C level, never used the char buffer
1841 implementation even when the char buffer for the wrapped object was
1842 explicitly requested (originally returned the read or write buffer).
1843 Now a TypeError is raised if the char buffer is not present but is
1844 requested.
1845
Georg Brandlddbaa662006-06-04 21:56:52 +00001846- Patch #1346214: Statements like "if 0: suite" are now again optimized
1847 away like they were in Python 2.4.
1848
Georg Brandlb7c8f542006-05-27 12:30:25 +00001849- Builtin exceptions are now full-blown new-style classes instead of
1850 instances pretending to be classes, which speeds up exception handling
1851 by about 80% in comparison to 2.5a2.
1852
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001853- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1854 Unicode 4.1.
1855
Georg Brandlf4ef1162006-05-26 18:03:31 +00001856- Patch #921466: sys.path_importer_cache is now used to cache valid and
1857 invalid file paths for the built-in import machinery which leads to
1858 fewer open calls on startup.
1859
Tim Peters696cf432006-05-24 21:10:40 +00001860- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1861 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1862 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1863 the number of input digits (it was and remains linear-time for bases
1864 2, 4, 8, 16 and 32).
1865
Tim Petersb713ec22006-05-23 18:45:30 +00001866- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1867 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1868 an integer close to ``sys.maxint``. This was repaired by patch
1869 #1335972, which also gives a nice speedup.
1870
Richard Jonescebbefc2006-05-23 18:28:17 +00001871- Patch #1337051: reduced size of frame objects.
1872
1873- PyErr_NewException now accepts a tuple of base classes as its
1874 "base" parameter.
1875
Richard Jones7c88dcc2006-05-23 10:37:38 +00001876- Patch #876206: function call speedup by retaining allocated frame
1877 objects.
1878
Georg Brandl7b90e162006-05-18 07:01:27 +00001879- Bug #1462152: file() now checks more thoroughly for invalid mode
1880 strings and removes a possible "U" before passing the mode to the
1881 C library function.
1882
Neal Norwitz1004a532006-05-15 07:17:23 +00001883- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1884
Neal Norwitz373f0a72006-05-15 07:04:36 +00001885- Bug #1487966: Fix SystemError with conditional expression in assignment
1886
Martin v. Löwis879768d2006-05-11 13:28:43 +00001887- WindowsError now has two error code attributes: errno, which carries
1888 the error values from errno.h, and winerror, which carries the error
1889 values from winerror.h. Previous versions put the winerror.h values
1890 (from GetLastError()) into the errno attribute.
1891
Martin v. Löwis77736712006-05-04 05:51:03 +00001892- Patch #1475845: Raise IndentationError for unexpected indent.
1893
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001894- Patch #1479181: split open() and file() from being aliases for each other.
1895
Tim Peters44bd9862006-06-01 13:49:23 +00001896- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1897 methods were always silently ignored by dictionaries when comparing keys.
1898 They are now passed through (except when using the C API function
1899 ``PyDict_GetItem()``, whose semantics did not change).
1900
1901- Bug #1456209: In some obscure cases it was possible for a class with a
1902 custom ``__eq__()`` method to confuse dict internals when class instances
1903 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1904 No, you don't have any code that did this ;-)

1912
Brett Cannon6ee7d012006-06-08 16:23:04 +00001913- Change binascii.hexlify to accept a read-only buffer instead of only a char
1914 buffer and actually follow its documentation.
1915
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001916- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1917
Nick Coghlanc649ec52006-05-29 12:43:05 +00001918- Patch #1478788 (modified version): The functional extension module has
1919 been renamed to _functools and a functools Python wrapper module added.
1920 This provides a home for additional function related utilities that are
1921 not specifically about functional programming. See PEP 309.
1922
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001923- Patch #1493701: performance enhancements for struct module.

Georg Brandl8d3342b2006-05-16 07:38:27 +00001927- Patch #1435422: zlib's compress and decompress objects now have a
1928 copy() method.
1929
Andrew MacIntyre92913322006-06-13 15:04:24 +00001930- Patch #1454481: thread stack size is now tunable at runtime for thread
1931 enabled builds on Windows and systems with Posix threads support.
1932
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001933- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1934 (up to the system limit of 32K characters).
1935
1936- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1937 As a result, these functions now raise WindowsError instead of OSError.
1938
Tim Peters7a822da2006-05-25 21:50:17 +00001939- ``time.clock()`` on Win64 should use the high-performance Windows
1940 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1941 Windows platforms).
1942
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001943- Calling Tk_Init twice is refused if the first call failed as that
1944 may deadlock.
1945
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001946- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1947 accept it without potentially using an uninitialized pointer.
1948
1949- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1950 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1955
Gregory P. Smith372b5832006-06-05 18:48:21 +00001956- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1957 parameter is supplied. [SF pybsddb bug #1477863]
1958
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001959- bsddb: the __len__ method of a DB object has been fixed to return correct
1960 results. It could previously incorrectly return 0 in some cases.
1961 Fixes SF bug 1493322 (pybsddb bug 1184012).
1962
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001963- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1964 aborts the db transaction safely when a modifier callback fails.
1965 Fixes SF python patch/bug #1408584.
1966
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001967- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001968 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001969 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1970 database calls that would previously deadlock. [SF python bug #775414]
1971

2000 double-byte encodings.
2001
Tim Peters43898b42006-06-14 04:09:25 +00002002- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2003 guarantee that adjacent triples in the return list always describe
2004 non-adjacent blocks. Previously, a pair of matching blocks could end
2005 up being described by multiple adjacent triples that formed a partition
2006 of the matching pair.
2007
Greg Ward0e0c9f42006-06-11 16:24:11 +00002008- Bug #1498146: fix optparse to handle Unicode strings in option help,

2014 clarify docs.
2015
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002016- The wsgiref package has been added to the standard library.
2017
Nick Coghlan676725d2006-06-08 13:54:49 +00002018- The functions update_wrapper() and wraps() have been added to the functools
2019 module. These make it easier to copy relevant metadata from the original
2020 function when writing wrapper functions.
2021
Tim Petersd6a9eef2006-06-05 01:48:21 +00002022- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2023 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002024
Martin v. Löwis3f767792006-06-04 19:36:28 +00002025- Patch #1359618: Speed up charmap encoder by using a trie structure
2026 for lookup.
2027
Tim Petersd609b1a2006-06-02 23:22:51 +00002028- The functions in the ``pprint`` module now sort dictionaries by key
2029 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2030 if and only if its display required more than one line, although that
2031 wasn't documented. The new behavior increases predictability; e.g.,
2032 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2033
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002034- Patch #1497027: try HTTP digest auth before basic auth in urllib2
2035 (thanks for J. J. Lee).
2036
Georg Brandl2b330372006-05-28 20:23:12 +00002037- Patch #1496206: improve urllib2 handling of passwords with respect to
2038 default HTTP and HTTPS ports.
2039
George Yoshidaf3c65de2006-05-28 16:39:09 +00002040- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
2041
Bob Ippolito7298f272006-05-23 18:43:47 +00002042- Patch #1281707: speed up gzip.readline.
2043
Georg Brandlb89316f2006-05-17 15:51:16 +00002044- Patch #1180296: Two new functions were added to the locale module:
2045 format_string() to get the effect of "format % items" but locale-aware,
2046 and currency() to format a monetary number with currency sign.
2047
Georg Brandle3a25832006-05-17 14:56:04 +00002048- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2049 and several features added, such as speed and geometry control.
2050
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002051- Patch #1488881: add support for external file objects in bz2 compressed
2052 tarfiles.
2053
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002054- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2055 stdout arguments, making it possible to redirect input and output
2056 for remote debugging.
2057
2058- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2059 a couple of issues, notably handling of long file names using the
2060 GNU LONGNAME extension.
2061
2062- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2063 new flag when ``name`` is already the name of an option flag.
2064
2065- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2066 package.
2067
2068- Patch #1472854: make the rlcompleter.Completer class usable on non-
2069 UNIX platforms.
2070
2071- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
2072
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00002073- Bug #1472827: correctly escape newlines and tabs in attribute values in
2074 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002104What's New in Python 2.5 alpha 2?
2105=================================
2106
2107*Release date: 27-APR-2006*
2108
2109Core and builtins
2110-----------------
2111
Thomas Heller1b046642006-04-18 18:51:06 +00002112- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2113 by converting these apis from macros into exported functions again:
2114
2115 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2116 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2117 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2118 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2119 PyRun_String Py_CompileString
2120
Martin v. Löwis45294a92006-04-18 06:24:08 +00002121- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2122
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002123- All uses of PyStructSequence_InitType have been changed to initialize
2124 the type objects only once, even if the interpreter is initialized
2125 multiple times.
2126
Neal Norwitz61546162006-04-14 05:20:28 +00002127- Bug #1454485, array.array('u') could crash the interpreter. This was
2128 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2129 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2130
2131- Py_UNICODE is unsigned. It was always documented as unsigned, but
2132 due to a bug had a signed value in previous versions.
2133
Tim Peters3a5e8b12006-04-11 01:44:07 +00002134- Patch #837242: ``id()`` of any Python object always gives a positive
2135 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2136 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002137 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002138 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002139
Tim Peters3a5e8b12006-04-11 01:44:07 +00002140 def __hash__(self):
2141 return id(self) # WRONG
2142
2143 because a hash result must be a (short) Python int but it was always
2144 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002145 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002146 was always usable as a hash value before this patch. That's no longer
2147 necessarily so.
2148
2149- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002150 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002151 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002152 #1454844)
2153
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002154- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2155 involving generators that have paused outside of any ``try`` or ``with``
2156 blocks. (In 2.5a1, a paused generator that was part of a reference
2157 cycle could not be garbage collected, regardless of whether it was
2158 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00002159
Anthony Baxter51bcb682006-04-05 14:51:42 +00002160Extension Modules

2165
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002166- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2167 fails with an error condition.
2168
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002169- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2170
2171- Bug #1117761: bsddb.*open() no longer raises an exception when using
2172 the cachesize parameter.
2173
2174- Bug #1149413: bsddb.*open() no longer raises an exception when using
2175 a temporary db (file=None) with the 'n' flag to truncate on open.
2176
2177- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2178 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002179
Armin Rigoa9017c32006-04-19 11:50:27 +00002180- Patch #1062014: AF_UNIX sockets under Linux have a special
2181 abstract namespace that is now fully supported.

2185
Peter Astrand7d1d4362006-07-14 14:04:45 +00002186- Bug #1223937: subprocess.CalledProcessError reports the exit status
2187 of the process using the returncode attribute, instead of
2188 abusing errno.
2189
Tim Peters711bf302006-04-25 03:31:36 +00002190- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2191 a doctest to be skipped (the code is not run, and the expected output
2192 or exception is ignored).
2193
Nick Coghlanda2268f2006-04-24 04:37:15 +00002194- Fixed contextlib.nested to cope with exceptions being raised and
2195 caught inside exit handlers.
2196
Greg Wardab05edc2006-04-23 03:47:58 +00002197- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2198 hex, octal, or binary; add ``append_const`` action; keep going if
2199 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2200 added ``epilog`` for better help generation).
2201
Tim Peters21fbd572006-04-21 21:18:10 +00002202- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2203 called from a thread spawned as a side effect of importing a module.
2204
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002205- The pydoc module now supports documenting packages contained in
2206 .zip or .egg files.
2207
2208- The pkgutil module now has several new utility functions, such
2209 as ``walk_packages()`` to support working with packages that are either
2210 in the filesystem or zip files.
2211
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002212- The mailbox module can now modify and delete messages from
2213 mailboxes, in addition to simply reading them. Thanks to Gregory
2214 K. Johnson for writing the code, and to the 2005 Google Summer of
2215 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002216
Tim Petersc7605f22006-04-17 21:12:33 +00002217- The ``__del__`` method of class ``local`` in module ``_threading_local``
2218 returned before accomplishing any of its intended cleanup.
2219
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002220- Patch #790710: Add breakpoint command lists in pdb.
2221

Martin v. Löwis4b501e62006-04-15 08:41:11 +00002224- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
2225
Anthony Baxtere29002c2006-04-12 12:07:31 +00002226- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2227 Windows. Bug #1469163.
2228
Phillip J. Eby47032112006-04-11 01:07:43 +00002229- The warnings, linecache, inspect, traceback, site, and doctest modules
2230 were updated to work correctly with modules imported from zipfiles or
2231 via other PEP 302 __loader__ objects.
2232
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002233- Patch #1467770: Reduce usage of subprocess._active to processes which
2234 the application hasn't waited on.

2241 direct output to an alternate file-like object.
2242
Anthony Baxter51bcb682006-04-05 14:51:42 +00002243Build

2245
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002246- The Makefile now has a reindent target, which runs reindent.py on
2247 the library.
2248
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002249- Patch #1470875: Building Python with MS Free Compiler

2254 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002255 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002256 CXX from --with-cxx-main, see description in README.
2257
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002258- Patch #1429775: Link extension modules with the shared libpython.
2259
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002260- Fixed a libffi build problem on MIPS systems.
2261
Tim Peters8931ff12006-05-13 23:28:20 +00002262- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2263 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2264 and "%zu" for unsigned integers of type ``size_t``.
2265
Anthony Baxter51bcb682006-04-05 14:51:42 +00002266Tests
2267-----
2268
Nick Coghlanda2268f2006-04-24 04:37:15 +00002269- test_contextlib now checks contextlib.nested can cope with exceptions
2270 being raised and caught inside exit handlers.
2271
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002272- test_cmd_line now checks operation of the -m and -c command switches
2273
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002274- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2275 it separately and by hand. It also wasn't cleaning up its changes to
2276 the current Decimal context.
2277
Thomas Woutersabd08882006-04-26 15:53:30 +00002278- regrtest.py now has a -M option to run tests that test the new limits of
2279 containers, on 64-bit architectures. Running these tests is only sensible
2280 on 64-bit machines with more than two gigabytes of memory. The argument
2281 passed is the maximum amount of memory for the tests to use.

2293
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002294- PEP 343: Added Context Types section to the library reference
2295 and attempted to bring other PEP 343 related documentation into
2296 line with the implementation and/or python-dev discussions.
2297
Tim Peters8dc73d22006-04-24 02:03:16 +00002298- Bug #1337990: clarified that ``doctest`` does not support examples

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002302What's New in Python 2.5 alpha 1?
2303=================================
2304
Anthony Baxterebed3f62006-04-03 15:03:44 +00002305*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002306
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002307Core and builtins
2308-----------------
2309
Nick Coghlan43832302006-04-23 17:04:07 +00002310- PEP 338: -m command line switch now delegates to runpy.run_module
2311 allowing it to support modules in packages and zipfiles
2312
Martin v. Löwisc661b882006-04-20 04:54:23 +00002313- On Windows, .DLL is not an accepted file name extension for
2314 extension modules anymore; extensions are only found if they
2315 end in .PYD.
2316
Martin v. Löwisea62d252006-04-03 10:56:49 +00002317- Bug #1421664: sys.stderr.encoding is now set to the same value as
2318 sys.stdout.encoding.
2319
Neal Norwitz92e212f2006-04-03 04:48:37 +00002320- __import__ accepts keyword arguments.
2321
Georg Brandlccadf842006-03-31 18:54:53 +00002322- Patch #1460496: round() now accepts keyword arguments.
2323
Anthony Baxter262c00a2006-03-30 10:53:17 +00002324- Fixed bug #1459029 - unicode reprs were double-escaped.
2325
Hye-Shik Changd478f342006-03-23 12:32:36 +00002326- Patch #1396919: The system scope threads are reenabled on FreeBSD
2327 5.4 and later versions.
2328
Neal Norwitze98ccf62006-03-23 05:39:47 +00002329- Bug #1115379: Compiling a Unicode string with an encoding declaration
2330 now gives a SyntaxError.
2331
Georg Brandlabd1ff82006-03-18 07:59:59 +00002332- Previously, Python code had no easy way to access the contents of a
2333 cell object. Now, a ``cell_contents`` attribute has been added
2334 (closes patch #1170323).
2335
Tim Peterscf79aac2006-03-16 01:14:46 +00002336- Patch #1123430: Python's small-object allocator now returns an arena to
2337 the system ``free()`` when all memory within an arena becomes unused
2338 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2339 freed. Some applications will see a drop in virtual memory size now,
2340 especially long-running applications that, from time to time, temporarily
2341 use a large number of small objects. Note that when Python returns an
2342 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002343 platform C library will in turn return that memory to the operating system.
2344 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002345 appears to be effective at least on Microsoft C and gcc-based systems.
2346 Thanks to Evan Jones for hard work and patience.
2347
Georg Brandl533ff6f2006-03-08 18:09:27 +00002348- Patch #1434038: property() now uses the getter's docstring if there is
2349 no "doc" argument given. This makes it possible to legitimately use
2350 property() as a decorator to produce a read-only property.
2351
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002352- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2353 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2354 of requiring an int or long in slicing and a few other contexts, enabling
2355 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2356
Neal Norwitz995acdf2006-03-07 05:01:00 +00002357- Fixed various bugs reported by Coverity's Prevent tool.
2358
Brett Cannonbf364092006-03-01 04:25:17 +00002359- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2360 new exception base class, BaseException, which has a new message attribute.
2361 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2362 Raising a string exception now raises a DeprecationWarning.
2363
Thomas Woutersfb609f42006-02-28 16:37:25 +00002364- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2365 explicitly relative, using 'from .module import name' to mean 'from the same
2366 package as this module is in. Imports without dots still default to the
2367 old relative-then-absolute, unless 'from __future__ import
2368 absolute_import' is used.
2369
Brett Cannona7446e32006-02-27 23:39:10 +00002370- Properly check if 'warnings' raises an exception (usually when a filter set
2371 to "error" is triggered) when raising a warning for raising string
2372 exceptions.
2373
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002374- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002375 The name was removed from Include/code.h.
2376
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002377- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002378
Guido van Rossum1968ad32006-02-25 22:38:04 +00002379- Patch 1433928:
2380 - The copy module now "copies" function objects (as atomic objects).
2381 - dict.__getitem__ now looks for a __missing__ hook before raising
2382 KeyError.
2383
Tim Peters84ef21c2006-02-28 20:39:06 +00002384- PEP 343: with statement implemented. Needs ``from __future__ import
2385 with_statement``. Use of 'with' as a variable will generate a warning.
2386 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002387 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002388 The following objects have __context__ methods:
2389 - The built-in file type.
2390 - The thread.LockType type.
2391 - The following types defined by the threading module:
2392 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2393 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002394
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002395- Fix the encodings package codec search function to only search
2396 inside its own package. Fixes problem reported in patch #1433198.
2397
2398 Note: Codec packages should implement and register their own
2399 codec search function. PEP 100 has the details.
2400
Tim Peters9ea89d22006-06-04 03:26:02 +00002401- PEP 353: Using ``Py_ssize_t`` as the index type.
2402
2403- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2404 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2405 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2406 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2407 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002408
Neal Norwitzfc76d632006-01-10 06:03:13 +00002409- Patch #1400181, fix unicode string formatting to not use the locale.
2410 This is how string objects work. u'%f' could use , instead of .
2411 for the decimal point. Now both strings and unicode always use periods.
2412
Neal Norwitz671b9e32006-01-09 07:07:12 +00002413- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2414 configure would break checking curses.h.
2415
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002416- Bug #959576: The pwd module is now builtin. This allows Python to be
2417 built on UNIX platforms without $HOME set.
2418
Neal Norwitzc10978f2005-12-19 06:07:16 +00002419- Bug #1072182, fix some potential problems if characters are signed.
2420
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002421- Bug #889500, fix line number on SyntaxWarning for global declarations.
2422
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002423- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2424
Neal Norwitze7214a12005-12-18 05:03:17 +00002425- Support for converting hex strings to floats no longer works.
2426 This was not portable. float('0x3') now raises a ValueError.
2427
Barry Warsaw2a38a862005-12-18 01:27:35 +00002428- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002429 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002430 is now displayed in interactive prompt banner.
2431
Georg Brandlfa166682005-12-17 21:45:17 +00002432- Implementation of PEP 341 - Unification of try/except and try/finally.
2433 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002434 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002435
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002436- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2437 now encodes backslash correctly.
2438
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002439- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2440
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002441- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002442 and long longs.
2443
Neal Norwitz67715f02005-11-09 06:59:35 +00002444- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002445 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002446 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002447
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002448- Replaced most Unicode charmap codecs with new ones using the
2449 new Unicode translate string feature in the builtin charmap
2450 codec; the codecs were created from the mapping tables available
2451 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2452 encodings now include a mapping for the Apple logo)
2453
Tim Peterse3547fd2005-12-16 23:13:57 +00002454- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002455
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002456- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002457
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002458- A new AST parser implementation was completed. The abstract
2459 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002460 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002461
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002462- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002463 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2464
Neal Norwitz708e51a2005-10-03 04:48:15 +00002465- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2466
Neal Norwitz11bd1192005-10-03 00:54:56 +00002467- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2468 Provide a warning when a directory is passed on the command line.
2469
Neal Norwitz40d37812005-10-02 01:48:49 +00002470- Fix segfault with invalid coding.
2471
2472- SF bug #772896: unknown encoding results in MemoryError.
2473
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002474- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002475 supported a __len__() method which evaluated to False when the iterator
2476 was empty.
2477
Guido van Rossum630db602005-09-20 18:49:54 +00002478- On 64-bit platforms, when __len__() returns a value that cannot be
2479 represented as a C int, raise OverflowError.
2480
Skip Montanarof8948ca2005-09-19 03:54:46 +00002481- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002482 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002483
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002484- SF bug #893549: parsing keyword arguments was broken with a few format
2485 codes.
2486
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002487- Changes donated by Elemental Security to make it work on AIX 5.3
2488 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2489 bug #105470: test_pwd fails on 64bit system (Opteron).
2490
Guido van Rossum539c6622005-09-14 17:49:54 +00002491- Changes donated by Elemental Security to make it work on HP-UX 11 on
2492 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2493
Georg Brandl4550b8d2005-08-26 06:43:52 +00002494- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002495 (fixes bug #1119418).
2496
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002497- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2498
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002499- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2500 exceptions that cause a function to exit.
2501
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002502- The implementation of set() and frozenset() was revised to use its
2503 own internal data structure. Memory consumption is reduced by 1/3
2504 and there are modest speed-ups as well. The API is unchanged.
2505
Tim Petersde7990b2005-07-17 23:45:23 +00002506- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2507
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002508- SF bug #1229429: PyObject_CallMethod failed to decrement some
2509 reference counts in some error exit cases.
2510
Tim Petersecc6e6a2005-07-10 22:30:55 +00002511- SF bug #1185883: Python's small-object memory allocator took over
2512 a block managed by the platform C library whenever a realloc specified
2513 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002514 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002515 portable way to copy data from the C-managed block into Python's
2516 small-object space without risking a memory fault. Python's small-object
2517 realloc now leaves such blocks under the control of the platform C
2518 realloc.
2519
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002520- SF bug #1232517: An overflow error was not detected properly when
2521 attempting to convert a large float to an int in os.utime().
2522
Raymond Hettinger3296e692005-06-29 23:29:56 +00002523- SF bug #1224347: hex longs now print with lowercase letters just
2524 like their int counterparts.
2525
Michael W. Hudson188d4362005-06-20 16:52:57 +00002526- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2527 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2528 interpreter states; back out that fix and do a better job (see
2529 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2530 for a longer write-up of the problem).
2531
Michael W. Hudsondf888462005-06-03 14:41:55 +00002532- SF patch #1180995: marshal now uses a binary format by default when
2533 serializing floats.
2534
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002535- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2536 the routines that promise to produce IEEE 754 binary representations
2537 of floats now simply copy bytes around.
2538
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002539- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2540 278.
2541
Brett Cannonc3647ac2005-04-26 03:45:26 +00002542- patch #1109424: int, long, float, complex, and unicode now check for the
2543 proper magic slot for type conversions when subclassed. Previously the
2544 magic slot was ignored during conversion. Semantics now match the way
2545 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002546 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002547 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002548 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002549
Barry Warsawc8d907c2005-04-19 23:43:40 +00002550- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2551 NULL, now raise an AttributeError when attempting to set or delete the
2552 attribute. Previously a TypeError was raised, but this was inconsistent
2553 with the equivalent pure-Python implementation.
2554
Michael W. Hudson774479c2005-04-18 08:46:17 +00002555- It is now safe to call PyGILState_Release() before
2556 PyEval_InitThreads() (note that if there is reason to believe there
2557 are multiple threads around you still must call PyEval_InitThreads()
2558 before using the Python API; this fix is for extension modules that
2559 have no way of knowing if Python is multi-threaded yet).
2560
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002561- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2562 disabled caused a crash.
2563
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002564- Bug #1165306: instancemethod_new allowed the creation of a method
2565 with im_class == im_self == NULL, which caused a crash when called.
2566
Tim Petersecc6e6a2005-07-10 22:30:55 +00002567- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002568 fixes the crash seen in bug #1165761
2569
Raymond Hettinger96229b12005-03-11 06:49:40 +00002570- Added two new builtins, any() and all().
2571
Brett Cannon409d8f22005-03-05 06:47:57 +00002572- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002573 (e.g., ``class C(): pass`` is no longer a syntax error).
2574 Patch #1176012 added support to the 'parser' module and 'compiler' package
2575 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002576
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002577- Patch #1115086: Support PY_LONGLONG in structmember.
2578
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002579- Bug #1155938: new style classes did not check that __init__() was
2580 returning None.
2581
Tim Petersecc6e6a2005-07-10 22:30:55 +00002582- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002583 ('\') with a specific error message.
2584
Martin v. Löwisff232d72005-03-03 09:24:38 +00002585- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2586
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002587- Bug #1124295: the __name__ attribute of file objects was
2588 inadvertently made inaccessible in restricted mode.
2589
Tim Petersecc6e6a2005-07-10 22:30:55 +00002590- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002591 an ferror() call.
2592
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002593- min() and max() now support key= arguments with the same meaning as in

Jeremy Hyltonab630502005-02-04 18:44:06 +00002604- The parser did not complain about future statements in illegal
2605 positions. It once again reports a syntax error if a future
2606 statement occurs after anything other than a doc string.
2607
Neil Schemenauercf52c072005-08-12 17:34:58 +00002608- Change the %s format specifier for str objects so that it returns a
2609 unicode instance if the argument is not an instance of basestring and
2610 calling __str__ on the argument returns a unicode instance.
2611
Tim Petersf4e69282006-02-27 17:15:31 +00002612- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2613 current thread state when the auto-GIL-state machinery knows about
2614 it (since the thread state is being deleted, continuing to remember it
2615 can't help, but can hurt if another thread happens to get created with
2616 the same thread id).

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002808- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2809 been renamed to have only a single underscore prefix. This was done to
2810 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002811
Nick Coghlan43832302006-04-23 17:04:07 +00002812- PEP 338: new module runpy defines a run_module function to support
2813 executing modules which provide access to source code or a code object
2814 via the PEP 302 import mechanisms.
2815
Anthony Baxter93f5b932006-04-03 08:05:07 +00002816- The email module's parsedate_tz function now sets the daylight savings

2824 in attribute values.
2825
Anthony Baxterc51ee692006-04-01 00:57:31 +00002826- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002827 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002828 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002829 module will not be built.
2830
Tim Petersc17976e2006-04-01 00:26:53 +00002831- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2832 aren't officially supported here, and trying to use them will probably
2833 raise an exception some day. But dicts have been allowed, and "mostly
2834 worked", so support for them won't go away without warning.
2835
Georg Brandl338ef7d2006-03-31 18:42:16 +00002836- Bug #1445068: getpass.getpass() can now be given an explicit stream
2837 argument to specify where to write the prompt.
2838

2854
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002855- email 4.0 package now integrated. This is largely the same as the email 3.0
2856 package that was included in Python 2.3, except that PEP 8 module names are
2857 now used (e.g. mail.message instead of email.Message). The MIME classes
2858 have been moved to a subpackage (e.g. email.mime.text instead of
2859 email.MIMEText). The old names are still supported for now. Several
2860 deprecated Message methods have been removed and lots of bugs have been

2864 (a subclass of tuple) that provides incremental decoders and encoders
2865 (a way to use stateful codecs without the stream API). Python functions
2866 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well

2951
2952 "The consensus of researchers in this area (at least as
2953 expressed at the NIST Hash Function Workshop 10/31/05),
2954 is that SHA-256 is a good choice for the time being, but
2955 that research should continue, and other alternatives may
2956 arise from this research. The larger SHA's also seem OK."

Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003122 flags on the HTTP listening socket.
3123
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003124- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3125 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3126
Fred Drakefbdeaad2006-07-29 16:56:15 +00003127- Patches #893642, #1039083: add allow_none, encoding arguments to
3128 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.

Martin v. Löwis1d11de62005-01-29 13:29:23 +00003130- Bug #1110478: Revert os.environ.update to do putenv again.
3131
Thomas Hellerd6c6e222005-01-20 19:20:16 +00003132- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3133
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003134- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3135
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003136- Enhancements to the csv module:
3137
3138 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003139 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003140 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003141 + Dialect parameter parsing has been re-implemented to improve error
3142 reporting.
3143 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3144 dictates.
3145 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003146 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003147 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003148 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3149 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003150 + reader now allows \r characters to be quoted (previously it only allowed
3151 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003152 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003153 + Dialect classes passed to the module are no longer instantiated by
3154 the module before being parsed (the former validation scheme required
3155 this, but the mechanism was unreliable).
3156 + The dialect registry now contains instances of the internal
3157 C-coded dialect type, rather than references to python objects.
3158 + the internal c-coded dialect type is now immutable.
3159 + register_dialect now accepts the same keyword dialect specifications
3160 as the reader and writer, allowing the user to register dialects
3161 without first creating a dialect class.
3162 + a configurable limit to the size of parsed fields has been added -
3163 previously, an unmatched quote character could result in the entire
3164 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003165 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003166 the parser field size limit (returning the former limit). The initial
3167 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003168 + A line_num attribute has been added to the reader object, which tracks
3169 the number of lines read from the source iterator. This is not
3170 the same as the number of records returned, as records can span
3171 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003172 + reader and writer objects were not being registered with the cyclic-GC.
3173 This has been fixed.
3174
Brett Cannone6539c42005-01-08 02:43:53 +00003175- _DummyThread objects in the threading module now delete self.__block that is
3176 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3177 lock primitives tend to be limited in number and thus should not be wasted on
3178 a _DummyThread object. Fixes bug #1089632.
3179
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003180- The imghdr module now detects Exif files.
3181
Raymond Hettinger6065d322004-12-20 23:51:53 +00003182- StringIO.truncate() now correctly adjusts the size attribute.
3183 (Bug #951915).
3184
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003185- locale.py now uses an updated locale alias table (built using
3186 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3187 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003188 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003189
Raymond Hettinger3557f422004-12-07 12:02:02 +00003190- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3191
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003192- the pickle module no longer accepts the deprecated None option in the
3193 args tuple returned by __reduce__().
3194
Brett Cannon84667c02004-12-07 03:25:18 +00003195- optparse now optionally imports gettext. This allows its use in setup.py.
3196
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003197- the pickle module no longer uses the deprecated bin parameter.
3198
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003199- the shelve module no longer uses the deprecated binary parameter.
3200
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003201- the pstats module no longer uses the deprecated ignore() method.
3202
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003203- the filecmp module no longer uses the deprecated use_statcache argument.
3204
Raymond Hettinger664347b2004-12-04 21:21:53 +00003205- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3206 extended or overridden by subclasses. Formerly, the subclassed method would
3207 be ignored by the rest of the module. (Bug #1078905).
3208
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003209- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003210 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003211
Walter Dörwald36733692004-12-22 12:50:50 +00003212- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3213 once when a size argument is given. This prevents a buffer overflow in the
3214 tokenizer with very long source lines.
3215
Barry Warsaw538561e2006-01-01 21:48:54 +00003216- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3217 immediately after creating the object, without any intervening
3218 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003219
Skip Montanaro05885812005-01-16 20:48:27 +00003220- The reconvert.quote function can now emit triple-quoted strings. The
3221 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003222
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003223- ``UserString.MutableString`` now supports negative indices in
3224 ``__setitem__`` and ``__delitem__``
3225
Greg Ward40407942005-03-05 02:53:17 +00003226- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3227 correctly.
3228
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003229- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3230 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3231 character even if the user has passed a size parameter to get a proper
3232 line ending. Remove the special handling of a "\r\n" that has been split
3233 between two lines.
3234
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003235- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3236 about illegal code points. The codec now supports PEP 293 style error
3237 handlers.
3238
Walter Dörwald78a78b02005-09-01 12:04:29 +00003239- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003240 from the input stream, so that the output is a byte string in the correct
3241 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003242
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003243- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3244 considering it exactly like a '*'.
3245
Walter Dörwald007f8df2005-10-09 19:42:27 +00003246- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3247 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003248
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003249- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3250
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003251- Patch #1413711: Certain patterns of differences were making difflib
3252 touch the recursion limit.
3253
Walter Dörwald58917a62006-03-31 15:26:22 +00003254- Bug #947906: An object oriented interface has been added to the calendar
3255 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003256 called as a script (e.g. via ``python -mcalendar``). Localized month and
3257 weekday names can be ouput (even if an exotic encoding is used) using
3258 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003259
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003260Build

3267
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003268- Build support for Win64-AMD64 was added.
3269
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003270- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3271
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003272- Patch #881820: look for openpty and forkpty also in libbsd.
3273
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003274- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3275 The zlib module is now builtin on Windows.
3276
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003277- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3278
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003279- Bug #1189330: configure did not correctly determine the necessary
3280 value of LINKCC if python was built with GCC 4.0.
3281
Trent Mick8321b422005-07-26 02:29:21 +00003282- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3283 vulnerability in zlib 1.2.1 and 1.2.2.
3284
Brett Cannon08cd5982005-04-24 22:26:38 +00003285- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3286 flags that change binary compatibility. Changes were also made to
3287 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003288 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003289
Bob Ippolitoed233462005-03-29 13:47:59 +00003290- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3291 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3292 no longer exists). This configure patch makes things right.
3293
Martin v. Löwise2713be2005-03-08 15:03:08 +00003294- Bug #1158607: Build with --disable-unicode again.
3295
Brett Cannon46d96232005-02-16 00:07:19 +00003296- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3297 defined. Discovered as a result of not being able to build on OS X.
3298
Brett Cannon516592f2004-12-07 00:42:59 +00003299- setup.py now uses the directories specified in LDFLAGS using the -L option
3300 and in CPPFLAGS using the -I option for adding library and include
3301 directories, respectively, for compiling extension modules against. This has
3302 led to the core being compiled using the values in CPPFLAGS. It also removes
3303 the need for the special-casing of both DarwinPorts and Fink for darwin since
3304 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3305 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3306 Fink, ``-I/opt/local/include`` for DarwinPorts).
3307
Brett Cannon43802422005-02-10 20:48:03 +00003308- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3309 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3310 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3311 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003313C API
3314-----
3315
Tim Petersc9d78aa2006-03-26 23:27:58 +00003316- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3317 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3318 is obtained via the ``PyObject_`` family, it must be released via the
3319 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3320 always been officially true, but when Python's small-object allocator was
3321 introduced, an attempt was made to cater to a few extension modules
3322 discovered at the time that obtained memory via ``PyObject_New`` but
3323 released it via ``PyMem_DEL``. It's years later, and if such code still
3324 exists it will fail now (probably with segfaults, but calling wrong
3325 low-level memory management functions can yield many symptoms).
3326
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003327- Added a C API for set and frozenset objects.
3328
Raymond Hettinger66517482004-12-03 11:45:13 +00003329- Removed PyRange_New().
3330
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003331- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3332 mapping argument now. This string is used as a mapping table. Byte values
3333 greater than the length of the string and 0xFFFE are treated as undefined
3334 mappings.
