24
Neal Norwitzd34e4272006-09-05 02:36:20 +000025- The return tuple from str.rpartition(sep) is (tail, sep, head) where
26 head is the original string if sep was not found.
27
Neal Norwitzdac090d2006-09-05 03:53:08 +000028- Bug #1520864: unpacking singleton tuples in list comprehensions and
29 generator expressions (x for x, in ... ) works again. Fixing this problem
30 required changing the .pyc magic number. This means that .pyc files
31 generated before 2.5c2 will be regenerated.

Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000101- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000102 compared equal or unequal to a string and a UnicodeDecodeError
103 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000104
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000105 Instead, the equal (==) and unequal (!=) comparison operators will
106 now issue a UnicodeWarning and interpret the two objects as
107 unequal. The UnicodeWarning can be filtered as desired using
108 the warning framework, e.g. silenced completely, turned into an
109 exception, logged, etc.
110
111 Note that compare operators other than equal and unequal will still
112 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000113
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000114- Fix segfault when doing string formatting on subclasses of long.
115
116- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
117 with new-style classes.
118
119- Fix bug related to __len__ functions returning negative values with
120 classic classes.
121
122- Patch #1538606, Fix __index__() clipping. There were some problems
123 discovered with the API and how integers that didn't fit into Py_ssize_t
124 were handled. This patch attempts to provide enough alternatives
125 to effectively use __index__.
126
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000127- Bug #1536021: __hash__ may now return long int; the final hash
128 value is obtained by invoking hash on the long int.
129
Thomas Hellerab1049c2006-08-08 17:37:00 +0000130- Bug #1536786: buffer comparison could emit a RuntimeWarning.
131
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000132- Bug #1535165: fixed a segfault in input() and raw_input() when
133 sys.stdin is closed.
134
Thomas Heller74d36f02006-08-04 18:17:40 +0000135- On Windows, the PyErr_Warn function is now exported from
136 the Python dll again.
137
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000138- Bug #1191458: tracing over for loops now produces a line event
139 on each iteration. Fixing this problem required changing the .pyc
140 magic number. This means that .pyc files generated before 2.5c1
141 will be regenerated.
142
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000143- Bug #1333982: string/number constants were inappropriately stored
144 in the byte code and co_consts even if they were not used, ie
145 immediately popped off the stack.
146
Georg Brandle9462c72006-08-04 18:03:37 +0000147- Fixed a reference-counting problem in property().

151-------
152
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000153- Fix a bug in the ``compiler`` package that caused invalid code to be
154 generated for generator expressions.
155
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000156- The distutils version has been changed to 2.5.0. The change to
157 keep it programmatically in sync with the Python version running
158 the code (introduced in 2.5b3) has been reverted. It will continue
159 to be maintained manually as static string literal.
160
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000161- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000162 and this cannot be converted to the required C type, an exception is
163 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000164 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000165
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000166- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000167 an exception.
168
Tim Petersc10c9d02006-09-05 02:18:09 +0000169- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000170 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000171 workarounds for clocks with low resolution, to stop the code yielding
172 duplicate UUIDs.
173
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000174- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
175 before raising SystemExit, allowing IDLE to honor quit() and exit().
176
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000177- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
178
Georg Brandl7a1af772006-08-14 21:55:28 +0000179- Patch #1536071: trace.py should now find the full module name of a
180 file correctly even on Windows.
181
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000182- logging's atexit hook now runs even if the rest of the module has
183 already been cleaned up.
184
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000185- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000186
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000187- Bug #1531405, format_exception no longer raises an exception if
188 str(exception) raised an exception.
189
Neil Schemenauer06ded092006-08-04 16:20:30 +0000190- Fix a bug in the ``compiler`` package that caused invalid code to be
191 generated for nested functions.

198
Georg Brandl3335a7a2006-08-14 21:42:55 +0000199- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
200 raises the correct exceptions.
201
Thomas Heller1ce433e2006-08-14 16:20:04 +0000202- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
203 '-no-stack-protector' compiler flag for OpenBSD has been removed.
204
Thomas Heller86720042006-08-14 11:17:48 +0000205- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
206 uses the _as_parameter_ attribute when objects are passed to foreign
207 function calls. The ctypes version number was changed to 1.0.1.
208
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000209- Bug #1530559, struct.pack raises TypeError where it used to convert.
210 Passing float arguments to struct.pack when integers are expected
211 now triggers a DeprecationWarning.

261Core and builtins
262-----------------
263
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000264- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000265 returned a long (see PEP 353).
266
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000267- Bug #1515471: string.replace() accepts character buffers again.
268
Neal Norwitz07aadb12006-07-30 06:55:48 +0000269- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
270 This provides the proper warning for struct.pack().
271 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
272
Neal Norwitz0d62a062006-07-30 06:53:31 +0000273- Patch #1531113: Fix augmented assignment with yield expressions.
274 Also fix a SystemError when trying to assign to yield expressions.
275
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000276- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
277 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
278 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
279 excessive filesystem operations during imports.
280
Tim Petersbc24eee2006-07-27 01:14:53 +0000281- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
282 operations on signed longs that are formally undefined by C.
283 Unfortunately, at least one compiler now cares about that, so complicated
284 the code to make that compiler happy again.
285
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000286- Bug #1524310: Properly report errors from FindNextFile in os.listdir.

289 path on Windows.
290
Neal Norwitze1fdb322006-07-21 05:32:28 +0000291- Fix some potential crashes found with failmalloc.
292
Neal Norwitze7563102006-07-17 01:00:16 +0000293- Fix warnings reported by Klocwork's static analysis tool.
294

296 had more than 255 blank lines.
297
Georg Brandl9dceedb2006-07-12 15:31:17 +0000298- Patch #1521179: Python now accepts the standard options ``--help`` and
299 ``--version`` as well as ``/?`` on Windows.

Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000301- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000302 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000303 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000304
Tim Peters112aad32006-07-19 00:03:19 +0000305- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000306 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000307 new ``sys._current_frames()`` returns a dictionary with one entry,
308 mapping the faux "thread id" 0 to the current frame.
309

314-------
315
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000316- Correction of patch #1455898: In the mbcs decoder, set final=False
317 for stream decoder, but final=True for the decode function.
318
Georg Brandl07fec3a2006-08-01 18:49:24 +0000319- os.urandom no longer masks unrelated exceptions like SystemExit or
320 KeyboardInterrupt.
321
Tim Peters4643c2f2006-08-10 22:45:34 +0000322- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000323 shutil.copytree on Windows
324
Georg Brandle34ac7c2006-07-30 11:07:23 +0000325- Bug #1002398: The documentation for os.path.sameopenfile now correctly
326 refers to file descriptors, not file objects.
327
Tim Petersc10c9d02006-09-05 02:18:09 +0000328- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000329 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000330 #1513611, and probably others.
331
Georg Brandledd9b0d2006-07-29 09:33:26 +0000332- Bug #1441397: The compiler module now recognizes module and function
333 docstrings correctly as it did in Python 2.4.
334
Tim Peters6f681472006-07-27 23:44:37 +0000335- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
336 lost that tests are sorted by name before being run. This rarely
337 matters for well-written tests, but can create baffling symptoms if
338 side effects from one test to the next affect outcomes. ``DocTestFinder``
339 has been changed to sort the list of tests it returns.
340
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000341- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000342 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000343
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000344- Bug #978833: Really close underlying socket in _socketobject.close.
345
Georg Brandl8c036cc2006-08-20 13:15:39 +0000346- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
347 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000348
Georg Brandlcf0c1722006-07-26 07:23:32 +0000349- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
350 to recursive calls and call it with the failing package name.
351
Martin v. Löwis0b483032006-07-25 09:53:12 +0000352- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
353
Georg Brandlc13c34c2006-07-24 14:09:56 +0000354- Patch #1515343: Fix printing of deprecated string exceptions with a
355 value in the traceback module.
356
Greg Ward48fae7a2006-07-23 16:05:51 +0000357- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
358
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000359- Patch #1524429: Use repr() instead of backticks in Tkinter again.
360
Brett Cannoncaebe222006-07-18 04:41:36 +0000361- Bug #1520914: Change time.strftime() to accept a zero for any position in its
362 argument tuple. For arguments where zero is illegal, the value is forced to
363 the minimum value that is correct. This is to support an undocumented but
364 common way people used to fill in inconsequential information in the time
365 tuple pre-2.4.
366
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000367- Patch #1220874: Update the binhex module for Mach-O.
368
Barry Warsawb110bad2006-07-21 14:51:07 +0000369- The email package has improved RFC 2231 support, specifically for
370 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
371 (name*0=<blah>) parameter continuations. This may change the types of
372 values returned from email.message.Message.get_param() and friends.
373 Specifically in some cases where non-encoded continuations were used,
374 get_param() used to return a 3-tuple of (None, None, string) whereas now it
375 will just return the string (since non-encoded continuations don't have
376 charset and language parts).
377
378 Also, whereas % values were decoded in all parameter continuations, they are
379 now only decoded in encoded parameter parts.
380
Ronald Oussoren3075e162006-07-25 20:28:55 +0000381- Bug #1517990: IDLE keybindings on MacOS X now work correctly
382
383- Bug #1517996: IDLE now longer shows the default Tk menu when a
384 path browser, class browser or debugger is the frontmost window on MacOS X
385
Barry Warsaw00decd72006-07-27 23:43:15 +0000386- Patch #1520294: Support for getset and member descriptors in types.py,
387 inspect.py, and pydoc.py. Specifically, this allows for querying the type
388 of an object against these built-in types and more importantly, for getting
389 their docstrings printed in the interactive interpreter's help() function.

393-----------------
394
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000395- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
396 a socket operation on a socket with a timeout, the exception will be
397 caught correctly. Previously, the exception was not caught.
398
Thomas Heller1393d6a2006-07-28 21:43:20 +0000399- Patch #1529514: The _ctypes extension is now compiled on more
400 openbsd target platforms.
401
Tim Peters9cab5932006-07-28 00:30:00 +0000402- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
403 a memory leak, affecting pickles and deep copies.
404
Tim Petersbc24eee2006-07-27 01:14:53 +0000405- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

407
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000408- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
409
Thomas Hellerce049a02006-07-14 17:51:14 +0000410- Patch #1521817: Index range checking on ctypes arrays containing
411 exactly one element enabled again. This allows iterating over these
412 arrays, without the need to check the array size before.
413
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000414- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000415 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000416 /dev/null in certain cases; this is now fixed.
417
Thomas Heller47d7a062006-07-12 08:43:47 +0000418- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
419 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000420
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000421- Because of a misspelled preprocessor symbol, ctypes was always
422 compiled without thread support; this is now fixed.
423
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000424- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
425 methods now allow their database parameter to be None as the
426 sleepycat API allows.
427
Matt Flemingec926502006-07-28 11:27:27 +0000428- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
429 bluetooth API compared with Linux and FreeBSD.
430
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000431Tests
432-----
433
434- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
435 how long the test file should take to play. Now accepts taking 2.93 secs
436 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
437
Georg Brandl4793aa32006-07-28 18:31:39 +0000438- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
439 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
440 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000447Mac
448---
449
450- PythonLauncher now works correctly when the path to the script contains
451 characters that are treated specially by the shell (such as quotes).
452
453- Bug #1527397: PythonLauncher now launches scripts with the working directory
454 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000455 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000456 expect.

464Core and builtins
465-----------------
466
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000467- Bug #1441486: The literal representation of -(sys.maxint - 1)
468 again evaluates to a int object, not a long.
469
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000470- Bug #1501934: The scope of global variables that are locally assigned
471 using augmented assignment is now correctly determined.
472
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000473- Bug #927248: Recursive method-wrapper objects can now safely
474 be released.
475
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000476- Bug #1417699: Reject locale-specific decimal point in float()
477 and atof().
478
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000479- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
480 omit a default "error" argument for NULL pointer. This allows
481 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000482
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000483- Bug #1519018: 'as' is now validated properly in import statements.
484
Neal Norwitz28746ab2006-07-09 22:14:42 +0000485- On 64 bit systems, int literals that use less than 64 bits are
486 now ints rather than longs.
487
Neal Norwitzed657552006-07-10 00:04:44 +0000488- Bug #1512814, Fix incorrect lineno's when code at module scope
489 started after line 256.
490
Tim Peters32a83612006-07-10 21:08:24 +0000491- New function ``sys._current_frames()`` returns a dict mapping thread
492 id to topmost thread stack frame. This is for expert use, and is
493 especially useful for debugging application deadlocks. The functionality
494 was previously available in Fazal Majid's ``threadframe`` extension
495 module, but it wasn't possible to do this in a wholly threadsafe way from
496 an extension.

Thomas Woutersadd19112006-07-05 11:03:49 +0000514- string.Template() now correctly handles tuple-values. Previously,
515 multi-value tuples would raise an exception and single-value tuples would
516 be treated as the value they contain, instead.

543
Brett Cannon53ab5b72006-06-22 16:49:14 +0000544- Bug #1510580: The 'warnings' module improperly required that a Warning
545 category be either a types.ClassType and a subclass of Warning. The proper
546 check is just that it is a subclass with Warning as the documentation states.
547
Georg Brandlad29e632006-06-21 17:45:17 +0000548- The compiler module now correctly compiles the new try-except-finally
549 statement (bug #1509132).
550
Neal Norwitz60373cd2006-06-22 06:30:50 +0000551- The wsgiref package is now installed properly on Unix.
552
Vinay Sajip28e57612006-07-01 10:45:20 +0000553- A bug was fixed in logging.config.fileConfig() which caused a crash on
554 shutdown when fileConfig() was called multiple times.
555
Gerhard Häring762fbd32006-07-02 17:48:30 +0000556- The sqlite3 module did cut off data from the SQLite database at the first
557 null character before sending it to a custom converter. This has been fixed
558 now.

Tim Peters112aad32006-07-19 00:03:19 +0000563- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
564 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
565 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000566
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000567- Assigning None to pointer type fields in ctypes structures possible
568 overwrote the wrong fields, this is fixed now.
569
570- Fixed a segfault in _ctypes when ctypes.wintypes were imported
571 on non-Windows platforms.
572
573- Bug #1518190: The ctypes.c_void_p constructor now accepts any
574 integer or long, without range checking.
575
576- Patch #1517790: It is now possible to use custom objects in the ctypes
577 foreign function argtypes sequence as long as they provide a from_param
578 method, no longer is it required that the object is a ctypes type.
579
580- The '_ctypes' extension module now works when Python is configured
581 with the --without-threads option.
582
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000583- Bug #1513646: os.access on Windows now correctly determines write

598
Tim Peters32a83612006-07-10 21:08:24 +0000599- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000600 Previously, the slight difference could cause compilation errors of the
601 'zlib' module on systems with more than one version of zlib.
602
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000603- The MSI compileall step was fixed to also support a TARGETDIR

634Core and builtins
635-----------------
636
Georg Brandla56b9152006-06-19 06:35:54 +0000637- Patch #1507676: Error messages returned by invalid abstract object operations
638 (such as iterating over an integer) have been improved and now include the
639 type of the offending object to help with debugging.
640
Brett Cannonea3912b2006-06-13 21:46:41 +0000641- Bug #992017: A classic class that defined a __coerce__() method that returned
642 its arguments swapped would infinitely recurse and segfault the interpreter.
643
Neal Norwitz909eb122006-06-12 02:13:21 +0000644- Fix the socket tests so they can be run concurrently.
645
Neal Norwitzb9845e72006-06-12 02:11:18 +0000646- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000647 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000648
Brett Cannon22565aa2006-06-09 22:31:23 +0000649- Bug #532646: object.__call__() will continue looking for the __call__
650 attribute on objects until one without one is found. This leads to recursion
651 when you take a class and set its __call__ attribute to an instance of the
652 class. Originally fixed for classic classes, but this fix is for new-style.
653 Removes the infinite_rec_3 crasher.
654
Georg Brandl24250812006-06-09 18:45:48 +0000655- The string and unicode methods startswith() and endswith() now accept
656 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
657
Brett Cannonde3b0522006-06-08 17:00:45 +0000658- Buffer objects, at the C level, never used the char buffer
659 implementation even when the char buffer for the wrapped object was
660 explicitly requested (originally returned the read or write buffer).
661 Now a TypeError is raised if the char buffer is not present but is
662 requested.
663
Georg Brandlddbaa662006-06-04 21:56:52 +0000664- Patch #1346214: Statements like "if 0: suite" are now again optimized
665 away like they were in Python 2.4.
666
Georg Brandlb7c8f542006-05-27 12:30:25 +0000667- Builtin exceptions are now full-blown new-style classes instead of
668 instances pretending to be classes, which speeds up exception handling
669 by about 80% in comparison to 2.5a2.
670
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000671- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
672 Unicode 4.1.
673
Georg Brandlf4ef1162006-05-26 18:03:31 +0000674- Patch #921466: sys.path_importer_cache is now used to cache valid and
675 invalid file paths for the built-in import machinery which leads to
676 fewer open calls on startup.
677
Tim Peters696cf432006-05-24 21:10:40 +0000678- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
679 of-2 bases. The largest speedup is for inputs with about 1000 decimal
680 digits. Conversion from non-power-of-2 bases remains quadratic-time in
681 the number of input digits (it was and remains linear-time for bases
682 2, 4, 8, 16 and 32).
683
Tim Petersb713ec22006-05-23 18:45:30 +0000684- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
685 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
686 an integer close to ``sys.maxint``. This was repaired by patch
687 #1335972, which also gives a nice speedup.
688
Richard Jonescebbefc2006-05-23 18:28:17 +0000689- Patch #1337051: reduced size of frame objects.
690
691- PyErr_NewException now accepts a tuple of base classes as its
692 "base" parameter.
693
Richard Jones7c88dcc2006-05-23 10:37:38 +0000694- Patch #876206: function call speedup by retaining allocated frame
695 objects.
696
Georg Brandl7b90e162006-05-18 07:01:27 +0000697- Bug #1462152: file() now checks more thoroughly for invalid mode
698 strings and removes a possible "U" before passing the mode to the
699 C library function.
700
Neal Norwitz1004a532006-05-15 07:17:23 +0000701- Patch #1488312, Fix memory alignment problem on SPARC in unicode
702
Neal Norwitz373f0a72006-05-15 07:04:36 +0000703- Bug #1487966: Fix SystemError with conditional expression in assignment
704
Martin v. Löwis879768d2006-05-11 13:28:43 +0000705- WindowsError now has two error code attributes: errno, which carries
706 the error values from errno.h, and winerror, which carries the error
707 values from winerror.h. Previous versions put the winerror.h values
708 (from GetLastError()) into the errno attribute.
709
Martin v. Löwis77736712006-05-04 05:51:03 +0000710- Patch #1475845: Raise IndentationError for unexpected indent.
711
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000712- Patch #1479181: split open() and file() from being aliases for each other.
713
Tim Peters44bd9862006-06-01 13:49:23 +0000714- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
715 methods were always silently ignored by dictionaries when comparing keys.
716 They are now passed through (except when using the C API function
717 ``PyDict_GetItem()``, whose semantics did not change).
718
719- Bug #1456209: In some obscure cases it was possible for a class with a
720 custom ``__eq__()`` method to confuse dict internals when class instances
721 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
722 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000724Extension Modules
725-----------------
726

728
729- Patch #1462338: Upgrade pyexpat to expat 2.0.0
730
Brett Cannon6ee7d012006-06-08 16:23:04 +0000731- Change binascii.hexlify to accept a read-only buffer instead of only a char
732 buffer and actually follow its documentation.
733
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000734- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
735
Nick Coghlanc649ec52006-05-29 12:43:05 +0000736- Patch #1478788 (modified version): The functional extension module has
737 been renamed to _functools and a functools Python wrapper module added.
738 This provides a home for additional function related utilities that are
739 not specifically about functional programming. See PEP 309.
740
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000741- Patch #1493701: performance enhancements for struct module.
742
Georg Brandl378d5922006-05-17 14:26:50 +0000743- Patch #1490224: time.altzone is now set correctly on Cygwin.
744
Georg Brandl8d3342b2006-05-16 07:38:27 +0000745- Patch #1435422: zlib's compress and decompress objects now have a
746 copy() method.
747
Andrew MacIntyre92913322006-06-13 15:04:24 +0000748- Patch #1454481: thread stack size is now tunable at runtime for thread
749 enabled builds on Windows and systems with Posix threads support.
750
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000751- On Win32, os.listdir now supports arbitrarily-long Unicode path names
752 (up to the system limit of 32K characters).
753
754- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
755 As a result, these functions now raise WindowsError instead of OSError.
756
Tim Peters7a822da2006-05-25 21:50:17 +0000757- ``time.clock()`` on Win64 should use the high-performance Windows
758 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
759 Windows platforms).
760
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000761- Calling Tk_Init twice is refused if the first call failed as that
762 may deadlock.
763
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000764- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
765 accept it without potentially using an uninitialized pointer.
766
767- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
768 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
769 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000770
Gregory P. Smith372b5832006-06-05 18:48:21 +0000771- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000772 [pybsddb project SF patch number 1466734]
773
Gregory P. Smith372b5832006-06-05 18:48:21 +0000774- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
775 parameter is supplied. [SF pybsddb bug #1477863]
776
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000777- bsddb: the __len__ method of a DB object has been fixed to return correct
778 results. It could previously incorrectly return 0 in some cases.
779 Fixes SF bug 1493322 (pybsddb bug 1184012).
780
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000781- bsddb: the bsddb.dbtables Modify method now raises the proper error and
782 aborts the db transaction safely when a modifier callback fails.
783 Fixes SF python patch/bug #1408584.
784
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000785- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000786 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000787 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
788 database calls that would previously deadlock. [SF python bug #775414]
789
Vinay Sajip28e57612006-07-01 10:45:20 +0000790- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000791
Walter Dörwald4994d952006-06-19 08:07:50 +0000792- Patch #1506645: add Python wrappers for the curses functions
793 is_term_resized, resize_term and resizeterm.

797
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000798- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
799 functions.
800
Martin v. Löwis3798da02006-06-17 18:44:27 +0000801- Patch #812986: Update turtle output even if not tracing.
802
Vinay Sajip28e57612006-07-01 10:45:20 +0000803- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000804 Tkinter.BaseWidget.
805
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000806- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
807
Martin v. Löwis337487e2006-06-17 09:15:14 +0000808- Patch #763580: Add name and value arguments to Tkinter variable
809 classes.
810
Georg Brandl83cc0d02006-06-14 08:50:03 +0000811- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
812 mime.types file for determining MIME types.
813
Georg Brandl2605ca82006-06-14 06:08:31 +0000814- Bug #1339007: Shelf objects now don't raise an exception in their
815 __del__ method when initialization failed.
816
Martin v. Löwisd8251432006-06-14 05:21:04 +0000817- Patch #1455898: The MBCS codec now supports the incremental mode for
818 double-byte encodings.
819
Tim Peters43898b42006-06-14 04:09:25 +0000820- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
821 guarantee that adjacent triples in the return list always describe
822 non-adjacent blocks. Previously, a pair of matching blocks could end
823 up being described by multiple adjacent triples that formed a partition
824 of the matching pair.
825
Greg Ward0e0c9f42006-06-11 16:24:11 +0000826- Bug #1498146: fix optparse to handle Unicode strings in option help,
827 description, and epilog.
828
Greg Wardd1c797e2006-06-11 14:42:41 +0000829- Bug #1366250: minor optparse documentation error.
830
Greg Ward7f547402006-06-11 00:40:49 +0000831- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
832 clarify docs.
833
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000834- The wsgiref package has been added to the standard library.
835
Nick Coghlan676725d2006-06-08 13:54:49 +0000836- The functions update_wrapper() and wraps() have been added to the functools
837 module. These make it easier to copy relevant metadata from the original
838 function when writing wrapper functions.
839
Tim Petersd6a9eef2006-06-05 01:48:21 +0000840- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
841 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000842
Martin v. Löwis3f767792006-06-04 19:36:28 +0000843- Patch #1359618: Speed up charmap encoder by using a trie structure
844 for lookup.
845
Tim Petersd609b1a2006-06-02 23:22:51 +0000846- The functions in the ``pprint`` module now sort dictionaries by key
847 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
848 if and only if its display required more than one line, although that
849 wasn't documented. The new behavior increases predictability; e.g.,
850 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
851
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000852- Patch #1497027: try HTTP digest auth before basic auth in urllib2
853 (thanks for J. J. Lee).
854
Georg Brandl2b330372006-05-28 20:23:12 +0000855- Patch #1496206: improve urllib2 handling of passwords with respect to
856 default HTTP and HTTPS ports.
857
George Yoshidaf3c65de2006-05-28 16:39:09 +0000858- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
859
Bob Ippolito7298f272006-05-23 18:43:47 +0000860- Patch #1281707: speed up gzip.readline.
861
Georg Brandlb89316f2006-05-17 15:51:16 +0000862- Patch #1180296: Two new functions were added to the locale module:
863 format_string() to get the effect of "format % items" but locale-aware,
864 and currency() to format a monetary number with currency sign.
865
Georg Brandle3a25832006-05-17 14:56:04 +0000866- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
867 and several features added, such as speed and geometry control.
868
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000869- Patch #1488881: add support for external file objects in bz2 compressed
870 tarfiles.
871
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000872- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
873 stdout arguments, making it possible to redirect input and output
874 for remote debugging.
875
876- Patch #1484695: Update the tarfile module to version 0.8. This fixes
877 a couple of issues, notably handling of long file names using the
878 GNU LONGNAME extension.
879
880- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
881 new flag when ``name`` is already the name of an option flag.
882
883- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
884 package.
885
886- Patch #1472854: make the rlcompleter.Completer class usable on non-
887 UNIX platforms.
888
889- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
890
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000891- Bug #1472827: correctly escape newlines and tabs in attribute values in

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000922What's New in Python 2.5 alpha 2?
923=================================
924
925*Release date: 27-APR-2006*
926
927Core and builtins
928-----------------
929
Thomas Heller1b046642006-04-18 18:51:06 +0000930- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
931 by converting these apis from macros into exported functions again:
932
933 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
934 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
935 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
936 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
937 PyRun_String Py_CompileString
938
Martin v. Löwis45294a92006-04-18 06:24:08 +0000939- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
940
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000941- All uses of PyStructSequence_InitType have been changed to initialize
942 the type objects only once, even if the interpreter is initialized
943 multiple times.
944
Neal Norwitz61546162006-04-14 05:20:28 +0000945- Bug #1454485, array.array('u') could crash the interpreter. This was
946 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
947 to unicode when it didn't make sense. 'u#' now requires a unicode string.
948
949- Py_UNICODE is unsigned. It was always documented as unsigned, but
950 due to a bug had a signed value in previous versions.
951
Tim Peters3a5e8b12006-04-11 01:44:07 +0000952- Patch #837242: ``id()`` of any Python object always gives a positive
953 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
954 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000955 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000956 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000957
Tim Peters3a5e8b12006-04-11 01:44:07 +0000958 def __hash__(self):
959 return id(self) # WRONG
960
961 because a hash result must be a (short) Python int but it was always
962 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000963 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000964 was always usable as a hash value before this patch. That's no longer
965 necessarily so.
966
967- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000968 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000969 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000970 #1454844)
971
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000972- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
973 involving generators that have paused outside of any ``try`` or ``with``
974 blocks. (In 2.5a1, a paused generator that was part of a reference
975 cycle could not be garbage collected, regardless of whether it was
976 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000978Extension Modules
979-----------------
980
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000981- Patch #1191065: Fix preprocessor problems on systems where recvfrom
982 is a macro.
983
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000984- Bug #1467952: os.listdir() now correctly raises an error if readdir()
985 fails with an error condition.
986
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000987- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
988
989- Bug #1117761: bsddb.*open() no longer raises an exception when using
990 the cachesize parameter.
991
992- Bug #1149413: bsddb.*open() no longer raises an exception when using
993 a temporary db (file=None) with the 'n' flag to truncate on open.
994
995- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
996 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000997
Armin Rigoa9017c32006-04-19 11:50:27 +0000998- Patch #1062014: AF_UNIX sockets under Linux have a special
999 abstract namespace that is now fully supported.
1000
Anthony Baxter51bcb682006-04-05 14:51:42 +00001001Library
1002-------
1003
Peter Astrand7d1d4362006-07-14 14:04:45 +00001004- Bug #1223937: subprocess.CalledProcessError reports the exit status
1005 of the process using the returncode attribute, instead of
1006 abusing errno.
1007
Tim Peters711bf302006-04-25 03:31:36 +00001008- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1009 a doctest to be skipped (the code is not run, and the expected output
1010 or exception is ignored).
1011
Nick Coghlanda2268f2006-04-24 04:37:15 +00001012- Fixed contextlib.nested to cope with exceptions being raised and
1013 caught inside exit handlers.
1014
Greg Wardab05edc2006-04-23 03:47:58 +00001015- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1016 hex, octal, or binary; add ``append_const`` action; keep going if
1017 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1018 added ``epilog`` for better help generation).
1019
Tim Peters21fbd572006-04-21 21:18:10 +00001020- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1021 called from a thread spawned as a side effect of importing a module.
1022
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001023- The pydoc module now supports documenting packages contained in
1024 .zip or .egg files.
1025
1026- The pkgutil module now has several new utility functions, such
1027 as ``walk_packages()`` to support working with packages that are either
1028 in the filesystem or zip files.
1029
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001030- The mailbox module can now modify and delete messages from
1031 mailboxes, in addition to simply reading them. Thanks to Gregory
1032 K. Johnson for writing the code, and to the 2005 Google Summer of
1033 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001034
Tim Petersc7605f22006-04-17 21:12:33 +00001035- The ``__del__`` method of class ``local`` in module ``_threading_local``
1036 returned before accomplishing any of its intended cleanup.
1037
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001038- Patch #790710: Add breakpoint command lists in pdb.
1039
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001040- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +00001042- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1043
Anthony Baxtere29002c2006-04-12 12:07:31 +00001044- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1045 Windows. Bug #1469163.
1046
Phillip J. Eby47032112006-04-11 01:07:43 +00001047- The warnings, linecache, inspect, traceback, site, and doctest modules
1048 were updated to work correctly with modules imported from zipfiles or
1049 via other PEP 302 __loader__ objects.
1050
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001051- Patch #1467770: Reduce usage of subprocess._active to processes which
1052 the application hasn't waited on.
1053
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001054- Patch #1462222: Fix Tix.Grid.
1055
Neal Norwitza31bf182006-04-09 03:35:43 +00001056- Fix exception when doing glob.glob('anything*/')
1057
Skip Montanaro262fb922006-04-21 02:31:07 +00001058- The pstats.Stats class accepts an optional stream keyword argument to
1059 direct output to an alternate file-like object.
1060
Anthony Baxter51bcb682006-04-05 14:51:42 +00001061Build
1062-----
1063
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001064- The Makefile now has a reindent target, which runs reindent.py on
1065 the library.
1066
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001067- Patch #1470875: Building Python with MS Free Compiler
1068
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001069- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001070
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001071- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1072 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001073 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001074 CXX from --with-cxx-main, see description in README.
1075
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001076- Patch #1429775: Link extension modules with the shared libpython.
1077
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001078- Fixed a libffi build problem on MIPS systems.
1079
Tim Peters8931ff12006-05-13 23:28:20 +00001080- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1081 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1082 and "%zu" for unsigned integers of type ``size_t``.
1083
Anthony Baxter51bcb682006-04-05 14:51:42 +00001084Tests
1085-----
1086
Nick Coghlanda2268f2006-04-24 04:37:15 +00001087- test_contextlib now checks contextlib.nested can cope with exceptions
1088 being raised and caught inside exit handlers.
1089
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001090- test_cmd_line now checks operation of the -m and -c command switches
1091
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001092- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1093 it separately and by hand. It also wasn't cleaning up its changes to
1094 the current Decimal context.
1095
Thomas Woutersabd08882006-04-26 15:53:30 +00001096- regrtest.py now has a -M option to run tests that test the new limits of
1097 containers, on 64-bit architectures. Running these tests is only sensible
1098 on 64-bit machines with more than two gigabytes of memory. The argument
1099 passed is the maximum amount of memory for the tests to use.
1100
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001101Tools
1102-----
1103
1104- Added the Python benchmark suite pybench to the Tools/ directory;
1105 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001107Documentation
1108-------------
1109
Tim Petersb06d28c2006-05-12 01:57:59 +00001110- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1111
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001112- PEP 343: Added Context Types section to the library reference
1113 and attempted to bring other PEP 343 related documentation into
1114 line with the implementation and/or python-dev discussions.
1115
Tim Peters8dc73d22006-04-24 02:03:16 +00001116- Bug #1337990: clarified that ``doctest`` does not support examples
1117 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +00001118

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001120What's New in Python 2.5 alpha 1?
1121=================================
1122
Anthony Baxterebed3f62006-04-03 15:03:44 +00001123*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001124
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001125Core and builtins
1126-----------------
1127
Nick Coghlan43832302006-04-23 17:04:07 +00001128- PEP 338: -m command line switch now delegates to runpy.run_module
1129 allowing it to support modules in packages and zipfiles
1130
Martin v. Löwisc661b882006-04-20 04:54:23 +00001131- On Windows, .DLL is not an accepted file name extension for
1132 extension modules anymore; extensions are only found if they
1133 end in .PYD.
1134
Martin v. Löwisea62d252006-04-03 10:56:49 +00001135- Bug #1421664: sys.stderr.encoding is now set to the same value as
1136 sys.stdout.encoding.
1137
Neal Norwitz92e212f2006-04-03 04:48:37 +00001138- __import__ accepts keyword arguments.
1139
Georg Brandlccadf842006-03-31 18:54:53 +00001140- Patch #1460496: round() now accepts keyword arguments.
1141
Anthony Baxter262c00a2006-03-30 10:53:17 +00001142- Fixed bug #1459029 - unicode reprs were double-escaped.
1143
Hye-Shik Changd478f342006-03-23 12:32:36 +00001144- Patch #1396919: The system scope threads are reenabled on FreeBSD
1145 5.4 and later versions.
1146
Neal Norwitze98ccf62006-03-23 05:39:47 +00001147- Bug #1115379: Compiling a Unicode string with an encoding declaration
1148 now gives a SyntaxError.
1149
Georg Brandlabd1ff82006-03-18 07:59:59 +00001150- Previously, Python code had no easy way to access the contents of a
1151 cell object. Now, a ``cell_contents`` attribute has been added
1152 (closes patch #1170323).
1153
Tim Peterscf79aac2006-03-16 01:14:46 +00001154- Patch #1123430: Python's small-object allocator now returns an arena to
1155 the system ``free()`` when all memory within an arena becomes unused
1156 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1157 freed. Some applications will see a drop in virtual memory size now,
1158 especially long-running applications that, from time to time, temporarily
1159 use a large number of small objects. Note that when Python returns an
1160 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001161 platform C library will in turn return that memory to the operating system.
1162 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001163 appears to be effective at least on Microsoft C and gcc-based systems.
1164 Thanks to Evan Jones for hard work and patience.
1165
Georg Brandl533ff6f2006-03-08 18:09:27 +00001166- Patch #1434038: property() now uses the getter's docstring if there is
1167 no "doc" argument given. This makes it possible to legitimately use
1168 property() as a decorator to produce a read-only property.
1169
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001170- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1171 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1172 of requiring an int or long in slicing and a few other contexts, enabling
1173 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1174
Neal Norwitz995acdf2006-03-07 05:01:00 +00001175- Fixed various bugs reported by Coverity's Prevent tool.
1176
Brett Cannonbf364092006-03-01 04:25:17 +00001177- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1178 new exception base class, BaseException, which has a new message attribute.
1179 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1180 Raising a string exception now raises a DeprecationWarning.
1181
Thomas Woutersfb609f42006-02-28 16:37:25 +00001182- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1183 explicitly relative, using 'from .module import name' to mean 'from the same
1184 package as this module is in. Imports without dots still default to the
1185 old relative-then-absolute, unless 'from __future__ import
1186 absolute_import' is used.
1187
Brett Cannona7446e32006-02-27 23:39:10 +00001188- Properly check if 'warnings' raises an exception (usually when a filter set
1189 to "error" is triggered) when raising a warning for raising string
1190 exceptions.
1191
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001192- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001193 The name was removed from Include/code.h.
1194
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001195- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001196
Guido van Rossum1968ad32006-02-25 22:38:04 +00001197- Patch 1433928:
1198 - The copy module now "copies" function objects (as atomic objects).
1199 - dict.__getitem__ now looks for a __missing__ hook before raising
1200 KeyError.
1201
Tim Peters84ef21c2006-02-28 20:39:06 +00001202- PEP 343: with statement implemented. Needs ``from __future__ import
1203 with_statement``. Use of 'with' as a variable will generate a warning.
1204 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001205 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001206 The following objects have __context__ methods:
1207 - The built-in file type.
1208 - The thread.LockType type.
1209 - The following types defined by the threading module:
1210 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1211 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001212
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001213- Fix the encodings package codec search function to only search
1214 inside its own package. Fixes problem reported in patch #1433198.
1215
1216 Note: Codec packages should implement and register their own
1217 codec search function. PEP 100 has the details.
1218
Tim Peters9ea89d22006-06-04 03:26:02 +00001219- PEP 353: Using ``Py_ssize_t`` as the index type.
1220
1221- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1222 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1223 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1224 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1225 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001226
Neal Norwitzfc76d632006-01-10 06:03:13 +00001227- Patch #1400181, fix unicode string formatting to not use the locale.
1228 This is how string objects work. u'%f' could use , instead of .
1229 for the decimal point. Now both strings and unicode always use periods.
1230
Neal Norwitz671b9e32006-01-09 07:07:12 +00001231- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1232 configure would break checking curses.h.
1233
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001234- Bug #959576: The pwd module is now builtin. This allows Python to be
1235 built on UNIX platforms without $HOME set.
1236
Neal Norwitzc10978f2005-12-19 06:07:16 +00001237- Bug #1072182, fix some potential problems if characters are signed.
1238
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001239- Bug #889500, fix line number on SyntaxWarning for global declarations.
1240
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001241- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1242
Neal Norwitze7214a12005-12-18 05:03:17 +00001243- Support for converting hex strings to floats no longer works.
1244 This was not portable. float('0x3') now raises a ValueError.
1245
Barry Warsaw2a38a862005-12-18 01:27:35 +00001246- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001247 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001248 is now displayed in interactive prompt banner.
1249
Georg Brandlfa166682005-12-17 21:45:17 +00001250- Implementation of PEP 341 - Unification of try/except and try/finally.
1251 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001252 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001253
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001254- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1255 now encodes backslash correctly.
1256
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001257- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1258
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001259- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001260 and long longs.
1261
Neal Norwitz67715f02005-11-09 06:59:35 +00001262- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001263 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001264 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001265
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001266- Replaced most Unicode charmap codecs with new ones using the
1267 new Unicode translate string feature in the builtin charmap
1268 codec; the codecs were created from the mapping tables available
1269 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1270 encodings now include a mapping for the Apple logo)
1271
Tim Peterse3547fd2005-12-16 23:13:57 +00001272- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001273
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001274- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001275
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001276- A new AST parser implementation was completed. The abstract
1277 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001278 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001279
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001280- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001281 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1282
Neal Norwitz708e51a2005-10-03 04:48:15 +00001283- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1284
Neal Norwitz11bd1192005-10-03 00:54:56 +00001285- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1286 Provide a warning when a directory is passed on the command line.
1287
Neal Norwitz40d37812005-10-02 01:48:49 +00001288- Fix segfault with invalid coding.
1289
1290- SF bug #772896: unknown encoding results in MemoryError.
1291
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001292- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001293 supported a __len__() method which evaluated to False when the iterator
1294 was empty.
1295
Guido van Rossum630db602005-09-20 18:49:54 +00001296- On 64-bit platforms, when __len__() returns a value that cannot be
1297 represented as a C int, raise OverflowError.
1298
Skip Montanarof8948ca2005-09-19 03:54:46 +00001299- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001300 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001301
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001302- SF bug #893549: parsing keyword arguments was broken with a few format
1303 codes.
1304
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001305- Changes donated by Elemental Security to make it work on AIX 5.3
1306 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1307 bug #105470: test_pwd fails on 64bit system (Opteron).
1308
Guido van Rossum539c6622005-09-14 17:49:54 +00001309- Changes donated by Elemental Security to make it work on HP-UX 11 on
1310 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1311
Georg Brandl4550b8d2005-08-26 06:43:52 +00001312- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001313 (fixes bug #1119418).
1314
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001315- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1316
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001317- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1318 exceptions that cause a function to exit.
1319
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001320- The implementation of set() and frozenset() was revised to use its
1321 own internal data structure. Memory consumption is reduced by 1/3
1322 and there are modest speed-ups as well. The API is unchanged.
1323
Tim Petersde7990b2005-07-17 23:45:23 +00001324- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1325
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001326- SF bug #1229429: PyObject_CallMethod failed to decrement some
1327 reference counts in some error exit cases.
1328
Tim Petersecc6e6a2005-07-10 22:30:55 +00001329- SF bug #1185883: Python's small-object memory allocator took over
1330 a block managed by the platform C library whenever a realloc specified
1331 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001332 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001333 portable way to copy data from the C-managed block into Python's
1334 small-object space without risking a memory fault. Python's small-object
1335 realloc now leaves such blocks under the control of the platform C
1336 realloc.
1337
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001338- SF bug #1232517: An overflow error was not detected properly when
1339 attempting to convert a large float to an int in os.utime().
1340
Raymond Hettinger3296e692005-06-29 23:29:56 +00001341- SF bug #1224347: hex longs now print with lowercase letters just
1342 like their int counterparts.
1343
Michael W. Hudson188d4362005-06-20 16:52:57 +00001344- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1345 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1346 interpreter states; back out that fix and do a better job (see
1347 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1348 for a longer write-up of the problem).
1349
Michael W. Hudsondf888462005-06-03 14:41:55 +00001350- SF patch #1180995: marshal now uses a binary format by default when
1351 serializing floats.
1352
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001353- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1354 the routines that promise to produce IEEE 754 binary representations
1355 of floats now simply copy bytes around.
1356
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001357- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1358 278.
1359
Brett Cannonc3647ac2005-04-26 03:45:26 +00001360- patch #1109424: int, long, float, complex, and unicode now check for the
1361 proper magic slot for type conversions when subclassed. Previously the
1362 magic slot was ignored during conversion. Semantics now match the way
1363 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001364 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001365 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001366 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001367
Barry Warsawc8d907c2005-04-19 23:43:40 +00001368- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1369 NULL, now raise an AttributeError when attempting to set or delete the
1370 attribute. Previously a TypeError was raised, but this was inconsistent
1371 with the equivalent pure-Python implementation.
1372
Michael W. Hudson774479c2005-04-18 08:46:17 +00001373- It is now safe to call PyGILState_Release() before
1374 PyEval_InitThreads() (note that if there is reason to believe there
1375 are multiple threads around you still must call PyEval_InitThreads()
1376 before using the Python API; this fix is for extension modules that
1377 have no way of knowing if Python is multi-threaded yet).
1378
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001379- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1380 disabled caused a crash.
1381
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001382- Bug #1165306: instancemethod_new allowed the creation of a method
1383 with im_class == im_self == NULL, which caused a crash when called.
1384
Tim Petersecc6e6a2005-07-10 22:30:55 +00001385- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001386 fixes the crash seen in bug #1165761
1387
Raymond Hettinger96229b12005-03-11 06:49:40 +00001388- Added two new builtins, any() and all().
1389
Brett Cannon409d8f22005-03-05 06:47:57 +00001390- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001391 (e.g., ``class C(): pass`` is no longer a syntax error).
1392 Patch #1176012 added support to the 'parser' module and 'compiler' package
1393 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001394
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001395- Patch #1115086: Support PY_LONGLONG in structmember.
1396
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001397- Bug #1155938: new style classes did not check that __init__() was
1398 returning None.
1399
Tim Petersecc6e6a2005-07-10 22:30:55 +00001400- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001401 ('\') with a specific error message.
1402
Martin v. Löwisff232d72005-03-03 09:24:38 +00001403- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1404
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001405- Bug #1124295: the __name__ attribute of file objects was
1406 inadvertently made inaccessible in restricted mode.
1407
Tim Petersecc6e6a2005-07-10 22:30:55 +00001408- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001409 an ferror() call.
1410
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001411- min() and max() now support key= arguments with the same meaning as in
1412 list.sort().
1413
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001414- The peephole optimizer now performs simple constant folding in expressions:
1415 (2+3) --> (5).
1416
Raymond Hettingera422c342005-01-11 03:03:27 +00001417- set and frozenset objects can now be marshalled. SF #1098985.
1418
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001419- Bug #1077106: Poor argument checking could cause memory corruption
1420 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001421
Jeremy Hyltonab630502005-02-04 18:44:06 +00001422- The parser did not complain about future statements in illegal
1423 positions. It once again reports a syntax error if a future
1424 statement occurs after anything other than a doc string.
1425
Neil Schemenauercf52c072005-08-12 17:34:58 +00001426- Change the %s format specifier for str objects so that it returns a
1427 unicode instance if the argument is not an instance of basestring and
1428 calling __str__ on the argument returns a unicode instance.
1429
Tim Petersf4e69282006-02-27 17:15:31 +00001430- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1431 current thread state when the auto-GIL-state machinery knows about
1432 it (since the thread state is being deleted, continuing to remember it
1433 can't help, but can hurt if another thread happens to get created with
1434 the same thread id).
1435
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001436Extension Modules
1437-----------------
1438
Georg Brandl43f08a82006-03-31 18:01:16 +00001439- Patch #1380952: fix SSL objects timing out on consecutive read()s
1440

1442
Anthony Baxterfa869072006-03-20 05:21:58 +00001443- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1444 In addition, the existing ulaw code was updated.
1445
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001446- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001447 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001448
Neal Norwitz10be10c2006-03-16 06:50:13 +00001449- Everything under lib-old was removed. This includes the following modules:
1450 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001451 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001452 util, whatsound, whrandom, zmod
1453
1454- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1455
1456- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001457 is deprecated. The undocumented re.engine variable no longer exists.
1458
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001459- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1460 SS2 (single-shift 2) escape sequences correctly.
1461
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001462- The unicodedata module was updated to the 4.1 version of the Unicode
1463 database. The 3.2 version is still available as unicodedata.db_3_2_0
1464 for applications that require this specific version (such as IDNA).
1465
Neal Norwitzb62c4332006-03-04 18:35:47 +00001466- The timing module is no longer built by default. It was deprecated
1467 in PEP 4 in Python 2.0 or earlier.
1468
Guido van Rossum1968ad32006-02-25 22:38:04 +00001469- Patch 1433928: Added a new type, defaultdict, to the collections module.
1470 This uses the new __missing__ hook behavior added to dict (see above).
1471
Georg Brandldbd83392006-02-20 09:42:33 +00001472- Bug #854823: socketmodule now builds on Sun platforms even when
1473 INET_ADDRSTRLEN is not defined.
1474
Georg Brandlf4f44152006-02-18 22:29:33 +00001475- Patch #1393157: os.startfile() now has an optional argument to specify
1476 a "command verb" to invoke on the file.
1477
Neal Norwitz082b2df2006-02-07 07:04:46 +00001478- Bug #876637, prevent stack corruption when socket descriptor

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001626- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1627 been renamed to have only a single underscore prefix. This was done to
1628 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001629
Nick Coghlan43832302006-04-23 17:04:07 +00001630- PEP 338: new module runpy defines a run_module function to support
1631 executing modules which provide access to source code or a code object
1632 via the PEP 302 import mechanisms.
1633
Anthony Baxter93f5b932006-04-03 08:05:07 +00001634- The email module's parsedate_tz function now sets the daylight savings

1642 in attribute values.
1643
Anthony Baxterc51ee692006-04-01 00:57:31 +00001644- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001645 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001646 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001647 module will not be built.
1648
Tim Petersc17976e2006-04-01 00:26:53 +00001649- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1650 aren't officially supported here, and trying to use them will probably
1651 raise an exception some day. But dicts have been allowed, and "mostly
1652 worked", so support for them won't go away without warning.
1653
Georg Brandl338ef7d2006-03-31 18:42:16 +00001654- Bug #1445068: getpass.getpass() can now be given an explicit stream

1672
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001673- email 4.0 package now integrated. This is largely the same as the email 3.0
1674 package that was included in Python 2.3, except that PEP 8 module names are
1675 now used (e.g. mail.message instead of email.Message). The MIME classes
1676 have been moved to a subpackage (e.g. email.mime.text instead of
1677 email.MIMEText). The old names are still supported for now. Several
1678 deprecated Message methods have been removed and lots of bugs have been
1679 fixed. More details can be found in the email package documentation.
1680
Walter Dörwald40108c92006-03-27 08:15:44 +00001681- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1682 (a subclass of tuple) that provides incremental decoders and encoders
1683 (a way to use stateful codecs without the stream API). Python functions
1684 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1685 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1686 have been added.

1689 a ValueError instead of a StopIteration now (like file and cString.String do).
1690 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1691 called before (like file and StringIO.StringIO do).

1759
Neal Norwitz338e7862005-12-23 21:27:46 +00001760- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
1761 LoadError as documented, instead of IOError. For compatibility,
1762 LoadError subclasses IOError.
1763
Brett Cannon3cbd0382005-12-16 22:49:23 +00001764- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001765 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1766 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1767 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1768 Ronald L. Rivest offered this advice for Python:
1769
1770 "The consensus of researchers in this area (at least as
1771 expressed at the NIST Hash Function Workshop 10/31/05),
1772 is that SHA-256 is a good choice for the time being, but
1773 that research should continue, and other alternatives may
1774 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001775
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001776- Added a subset of Fredrik Lundh's ElementTree package. Available

1829 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001830 correct line numbers for decoding errors in source code.

1853 to W3C name (404 -> 'Not Found'). RFE #1216944.
1854
Georg Brandl9e43acf2005-07-04 17:16:07 +00001855- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1856 as this can cause problems with apps closing all file descriptors.

1869 Bug #1224621.
1870
Raymond Hettinger68c04532005-06-10 11:05:19 +00001871- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001872 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001873 the generate_tokens() function now accepts a callable argument that
1874 terminates by raising StopIteration.
1875
Georg Brandl9166e1a2005-06-04 09:20:03 +00001876- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1880
Skip Montanaro174dd222005-05-14 20:54:16 +00001881- Patch #1120353: The xmlrpclib module provides better, more transparent,

1884 class at all.
1885
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001886- distutils.commands.upload was added to support uploading distribution

1890 them to PyPI.
1891
Raymond Hettinger267b8682005-03-27 10:47:39 +00001892- decimal operator and comparison methods now return NotImplemented
1893 instead of raising a TypeError when interacting with other types. This
1894 allows other classes to implement __radd__ style methods and have them
1895 work as expected.
1896
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001897- Bug #1163325: Decimal infinities failed to hash. Attempting to
1898 hash a NaN raised an InvalidOperation instead of a TypeError.
1899
Tim Petersecc6e6a2005-07-10 22:30:55 +00001900- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1934
Guido van Rossumd0641422005-02-03 15:01:24 +00001935- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1936 disables recursive traversal through instance attributes, which can
1937 be exploited in various ways.
1938
Tim Peterse3547fd2005-12-16 23:13:57 +00001939- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001940 flags on the HTTP listening socket.
1941
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001942- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1943 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1944
Fred Drakefbdeaad2006-07-29 16:56:15 +00001945- Patches #893642, #1039083: add allow_none, encoding arguments to
1946 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001947

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001950- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1951
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001952- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1953
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001954- Enhancements to the csv module:
1955
1956 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001957 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001958 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001959 + Dialect parameter parsing has been re-implemented to improve error
1960 reporting.
1961 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1962 dictates.
1963 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001964 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001965 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001966 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1967 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001968 + reader now allows \r characters to be quoted (previously it only allowed
1969 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001970 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001971 + Dialect classes passed to the module are no longer instantiated by
1972 the module before being parsed (the former validation scheme required
1973 this, but the mechanism was unreliable).
1974 + The dialect registry now contains instances of the internal
1975 C-coded dialect type, rather than references to python objects.
1976 + the internal c-coded dialect type is now immutable.
1977 + register_dialect now accepts the same keyword dialect specifications
1978 as the reader and writer, allowing the user to register dialects
1979 without first creating a dialect class.
1980 + a configurable limit to the size of parsed fields has been added -
1981 previously, an unmatched quote character could result in the entire
1982 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001983 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001984 the parser field size limit (returning the former limit). The initial
1985 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001986 + A line_num attribute has been added to the reader object, which tracks
1987 the number of lines read from the source iterator. This is not
1988 the same as the number of records returned, as records can span
1989 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001990 + reader and writer objects were not being registered with the cyclic-GC.
1991 This has been fixed.
1992
Brett Cannone6539c42005-01-08 02:43:53 +00001993- _DummyThread objects in the threading module now delete self.__block that is
1994 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1995 lock primitives tend to be limited in number and thus should not be wasted on
1996 a _DummyThread object. Fixes bug #1089632.
1997
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001998- The imghdr module now detects Exif files.
1999
Raymond Hettinger6065d322004-12-20 23:51:53 +00002000- StringIO.truncate() now correctly adjusts the size attribute.
2001 (Bug #951915).
2002
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002003- locale.py now uses an updated locale alias table (built using
2004 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2005 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002006 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002007
Raymond Hettinger3557f422004-12-07 12:02:02 +00002008- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2009
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002010- the pickle module no longer accepts the deprecated None option in the
2011 args tuple returned by __reduce__().
2012
Brett Cannon84667c02004-12-07 03:25:18 +00002013- optparse now optionally imports gettext. This allows its use in setup.py.
2014
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002015- the pickle module no longer uses the deprecated bin parameter.
2016
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002017- the shelve module no longer uses the deprecated binary parameter.
2018
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002019- the pstats module no longer uses the deprecated ignore() method.
2020
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002021- the filecmp module no longer uses the deprecated use_statcache argument.
2022
Raymond Hettinger664347b2004-12-04 21:21:53 +00002023- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2024 extended or overridden by subclasses. Formerly, the subclassed method would
2025 be ignored by the rest of the module. (Bug #1078905).
2026
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002027- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002028 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002029
Walter Dörwald36733692004-12-22 12:50:50 +00002030- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2031 once when a size argument is given. This prevents a buffer overflow in the
2032 tokenizer with very long source lines.
2033
Barry Warsaw538561e2006-01-01 21:48:54 +00002034- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2035 immediately after creating the object, without any intervening
2036 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002037
Skip Montanaro05885812005-01-16 20:48:27 +00002038- The reconvert.quote function can now emit triple-quoted strings. The
2039 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002040
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002041- ``UserString.MutableString`` now supports negative indices in
2042 ``__setitem__`` and ``__delitem__``
2043
Greg Ward40407942005-03-05 02:53:17 +00002044- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2045 correctly.
2046
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002047- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2048 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2049 character even if the user has passed a size parameter to get a proper
2050 line ending. Remove the special handling of a "\r\n" that has been split
2051 between two lines.
2052
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002053- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2054 about illegal code points. The codec now supports PEP 293 style error
2055 handlers.
2056
Walter Dörwald78a78b02005-09-01 12:04:29 +00002057- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002058 from the input stream, so that the output is a byte string in the correct
2059 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002060
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002061- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2062 considering it exactly like a '*'.
2063
Walter Dörwald007f8df2005-10-09 19:42:27 +00002064- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2065 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002066
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002067- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2068
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002069- Patch #1413711: Certain patterns of differences were making difflib
2070 touch the recursion limit.
2071
Walter Dörwald58917a62006-03-31 15:26:22 +00002072- Bug #947906: An object oriented interface has been added to the calendar
2073 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002074 called as a script (e.g. via ``python -mcalendar``). Localized month and
2075 weekday names can be ouput (even if an exotic encoding is used) using
2076 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002077
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002078Build
2079-----
2080
Neal Norwitz602d3392006-03-31 08:21:40 +00002081- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2082 by using -mieee gcc option.
2083
Martin v. Löwis86d66262006-02-17 08:40:11 +00002084- Patch #1432345: Make python compile on DragonFly.
2085
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002086- Build support for Win64-AMD64 was added.
2087
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002088- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2089
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002090- Patch #881820: look for openpty and forkpty also in libbsd.
2091
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002092- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2093 The zlib module is now builtin on Windows.
2094
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002095- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2096
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002097- Bug #1189330: configure did not correctly determine the necessary
2098 value of LINKCC if python was built with GCC 4.0.
2099
Trent Mick8321b422005-07-26 02:29:21 +00002100- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2101 vulnerability in zlib 1.2.1 and 1.2.2.
2102
Brett Cannon08cd5982005-04-24 22:26:38 +00002103- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2104 flags that change binary compatibility. Changes were also made to
2105 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002106 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002107
Bob Ippolitoed233462005-03-29 13:47:59 +00002108- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2109 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2110 no longer exists). This configure patch makes things right.
2111
Martin v. Löwise2713be2005-03-08 15:03:08 +00002112- Bug #1158607: Build with --disable-unicode again.
2113
Brett Cannon46d96232005-02-16 00:07:19 +00002114- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2115 defined. Discovered as a result of not being able to build on OS X.
2116
Brett Cannon516592f2004-12-07 00:42:59 +00002117- setup.py now uses the directories specified in LDFLAGS using the -L option
2118 and in CPPFLAGS using the -I option for adding library and include
2119 directories, respectively, for compiling extension modules against. This has
2120 led to the core being compiled using the values in CPPFLAGS. It also removes
2121 the need for the special-casing of both DarwinPorts and Fink for darwin since
2122 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2123 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2124 Fink, ``-I/opt/local/include`` for DarwinPorts).
2125
Brett Cannon43802422005-02-10 20:48:03 +00002126- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2127 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2128 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2129 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002131C API
2132-----
2133
Tim Petersc9d78aa2006-03-26 23:27:58 +00002134- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2135 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2136 is obtained via the ``PyObject_`` family, it must be released via the
2137 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2138 always been officially true, but when Python's small-object allocator was
2139 introduced, an attempt was made to cater to a few extension modules
2140 discovered at the time that obtained memory via ``PyObject_New`` but
2141 released it via ``PyMem_DEL``. It's years later, and if such code still
2142 exists it will fail now (probably with segfaults, but calling wrong
2143 low-level memory management functions can yield many symptoms).
2144
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002145- Added a C API for set and frozenset objects.
2146
Raymond Hettinger66517482004-12-03 11:45:13 +00002147- Removed PyRange_New().
2148
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002149- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2150 mapping argument now. This string is used as a mapping table. Byte values
2151 greater than the length of the string and 0xFFFE are treated as undefined
2152 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002159
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002160- Patch #1276356: New resource "urlfetch" is implemented. This enables
2161 even impatient people to run tests that require remote files.
