48-----------------

Marc-André Lemburg040f76b2006-08-14 10:55:19 +000050- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000051 compared equal or unequal to a string and a UnicodeDecodeError
52 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +000053
Marc-André Lemburg040f76b2006-08-14 10:55:19 +000054 Instead, the equal (==) and unequal (!=) comparison operators will
55 now issue a UnicodeWarning and interpret the two objects as
56 unequal. The UnicodeWarning can be filtered as desired using
57 the warning framework, e.g. silenced completely, turned into an
58 exception, logged, etc.
59
60 Note that compare operators other than equal and unequal will still
61 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +000062
Marc-André Lemburg757ea272006-08-14 11:44:34 +000063- Fix segfault when doing string formatting on subclasses of long.
64
65- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
66 with new-style classes.
67
68- Fix bug related to __len__ functions returning negative values with
69 classic classes.
70
71- Patch #1538606, Fix __index__() clipping. There were some problems
72 discovered with the API and how integers that didn't fit into Py_ssize_t
73 were handled. This patch attempts to provide enough alternatives
74 to effectively use __index__.
75
Martin v. Löwisab2f8f72006-08-09 07:57:39 +000076- Bug #1536021: __hash__ may now return long int; the final hash
77 value is obtained by invoking hash on the long int.
78
Thomas Hellerab1049c2006-08-08 17:37:00 +000079- Bug #1536786: buffer comparison could emit a RuntimeWarning.
80
Georg Brandl7e3ba2a2006-08-06 08:23:54 +000081- Bug #1535165: fixed a segfault in input() and raw_input() when
82 sys.stdin is closed.
83
Thomas Heller74d36f02006-08-04 18:17:40 +000084- On Windows, the PyErr_Warn function is now exported from
85 the Python dll again.
86
Neal Norwitz4ffedad2006-08-04 04:58:47 +000087- Bug #1191458: tracing over for loops now produces a line event
88 on each iteration. Fixing this problem required changing the .pyc
89 magic number. This means that .pyc files generated before 2.5c1
90 will be regenerated.
91
Neal Norwitz0cbd8052006-08-04 05:09:28 +000092- Bug #1333982: string/number constants were inappropriately stored
93 in the byte code and co_consts even if they were not used, ie
94 immediately popped off the stack.
95
Georg Brandle9462c72006-08-04 18:03:37 +000096- Fixed a reference-counting problem in property().
97
Neal Norwitzff4b63b2006-08-04 04:50:21 +000098
99Library
100-------
101
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000102- Fix a bug in the ``compiler`` package that caused invalid code to be
103 generated for generator expressions.
104
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000105- The distutils version has been changed to 2.5.0. The change to
106 keep it programmatically in sync with the Python version running
107 the code (introduced in 2.5b3) has been reverted. It will continue
108 to be maintained manually as static string literal.
109
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000110- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000111 and this cannot be converted to the required C type, an exception is
112 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000113 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000114
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000115- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000116 an exception.
117
Anthony Baxter58179592006-08-16 13:08:25 +0000118- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000119 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000120 workarounds for clocks with low resolution, to stop the code yielding
121 duplicate UUIDs.
122
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000123- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
124 before raising SystemExit, allowing IDLE to honor quit() and exit().
125
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000126- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
127
Georg Brandl7a1af772006-08-14 21:55:28 +0000128- Patch #1536071: trace.py should now find the full module name of a
129 file correctly even on Windows.
130
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000131- logging's atexit hook now runs even if the rest of the module has
132 already been cleaned up.
133
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000134- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000135
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000136- Bug #1531405, format_exception no longer raises an exception if
137 str(exception) raised an exception.
138
Neil Schemenauer06ded092006-08-04 16:20:30 +0000139- Fix a bug in the ``compiler`` package that caused invalid code to be
140 generated for nested functions.

147
Georg Brandl3335a7a2006-08-14 21:42:55 +0000148- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
149 raises the correct exceptions.
150
Thomas Heller1ce433e2006-08-14 16:20:04 +0000151- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
152 '-no-stack-protector' compiler flag for OpenBSD has been removed.
153
Thomas Heller86720042006-08-14 11:17:48 +0000154- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
155 uses the _as_parameter_ attribute when objects are passed to foreign
156 function calls. The ctypes version number was changed to 1.0.1.
157
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000158- Bug #1530559, struct.pack raises TypeError where it used to convert.
159 Passing float arguments to struct.pack when integers are expected
160 now triggers a DeprecationWarning.
161
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000162

Neal Norwitza1f10902006-07-12 07:28:29 +0000209
210Core and builtins
211-----------------
212
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000213- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000214 returned a long (see PEP 353).
215
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000216- Bug #1515471: string.replace() accepts character buffers again.
217
Neal Norwitz07aadb12006-07-30 06:55:48 +0000218- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
219 This provides the proper warning for struct.pack().
220 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
221
Neal Norwitz0d62a062006-07-30 06:53:31 +0000222- Patch #1531113: Fix augmented assignment with yield expressions.
223 Also fix a SystemError when trying to assign to yield expressions.
224
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000225- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
226 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
227 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
228 excessive filesystem operations during imports.
229
Tim Petersbc24eee2006-07-27 01:14:53 +0000230- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
231 operations on signed longs that are formally undefined by C.
232 Unfortunately, at least one compiler now cares about that, so complicated
233 the code to make that compiler happy again.
234
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000235- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
236
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000237- Patch #1232023: Stop including current directory in search
238 path on Windows.
239
Neal Norwitze1fdb322006-07-21 05:32:28 +0000240- Fix some potential crashes found with failmalloc.
241
Neal Norwitze7563102006-07-17 01:00:16 +0000242- Fix warnings reported by Klocwork's static analysis tool.
243
Neal Norwitz84be93b2006-07-16 01:50:38 +0000244- Bug #1512814, Fix incorrect lineno's when code within a function
245 had more than 255 blank lines.
246
Georg Brandl9dceedb2006-07-12 15:31:17 +0000247- Patch #1521179: Python now accepts the standard options ``--help`` and
248 ``--version`` as well as ``/?`` on Windows.
249
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000250- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000251 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000252 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000253
Tim Peters112aad32006-07-19 00:03:19 +0000254- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000255 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000256 new ``sys._current_frames()`` returns a dictionary with one entry,
257 mapping the faux "thread id" 0 to the current frame.
258
Ronald Oussoren3075e162006-07-25 20:28:55 +0000259- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000260

Neal Norwitza1f10902006-07-12 07:28:29 +0000262Library
263-------
264
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000265- Correction of patch #1455898: In the mbcs decoder, set final=False
266 for stream decoder, but final=True for the decode function.
267
Georg Brandl07fec3a2006-08-01 18:49:24 +0000268- os.urandom no longer masks unrelated exceptions like SystemExit or
269 KeyboardInterrupt.
270
Tim Peters4643c2f2006-08-10 22:45:34 +0000271- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000272 shutil.copytree on Windows
273
Georg Brandle34ac7c2006-07-30 11:07:23 +0000274- Bug #1002398: The documentation for os.path.sameopenfile now correctly
275 refers to file descriptors, not file objects.
276
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000277- The renaming of the xml package to xmlcore, and the import hackery done
278 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000279 #1513611, and probably others.
280
Georg Brandledd9b0d2006-07-29 09:33:26 +0000281- Bug #1441397: The compiler module now recognizes module and function
282 docstrings correctly as it did in Python 2.4.
283
Tim Peters6f681472006-07-27 23:44:37 +0000284- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
285 lost that tests are sorted by name before being run. This rarely
286 matters for well-written tests, but can create baffling symptoms if
287 side effects from one test to the next affect outcomes. ``DocTestFinder``
288 has been changed to sort the list of tests it returns.
289
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000290- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000291 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000292
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000293- Bug #978833: Really close underlying socket in _socketobject.close.
294
Georg Brandldb232dc2006-08-20 13:15:43 +0000295- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
296 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000297
Georg Brandlcf0c1722006-07-26 07:23:32 +0000298- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
299 to recursive calls and call it with the failing package name.
300
Martin v. Löwis0b483032006-07-25 09:53:12 +0000301- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
302
Georg Brandlc13c34c2006-07-24 14:09:56 +0000303- Patch #1515343: Fix printing of deprecated string exceptions with a

Greg Ward48fae7a2006-07-23 16:05:51 +0000306- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
307
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000308- Patch #1524429: Use repr() instead of backticks in Tkinter again.
309
Brett Cannoncaebe222006-07-18 04:41:36 +0000310- Bug #1520914: Change time.strftime() to accept a zero for any position in its
311 argument tuple. For arguments where zero is illegal, the value is forced to
312 the minimum value that is correct. This is to support an undocumented but
313 common way people used to fill in inconsequential information in the time
314 tuple pre-2.4.
315
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000316- Patch #1220874: Update the binhex module for Mach-O.
317
Barry Warsawb110bad2006-07-21 14:51:07 +0000318- The email package has improved RFC 2231 support, specifically for
319 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
320 (name*0=<blah>) parameter continuations. This may change the types of
321 values returned from email.message.Message.get_param() and friends.
322 Specifically in some cases where non-encoded continuations were used,
323 get_param() used to return a 3-tuple of (None, None, string) whereas now it
324 will just return the string (since non-encoded continuations don't have
325 charset and language parts).
326
327 Also, whereas % values were decoded in all parameter continuations, they are
328 now only decoded in encoded parameter parts.
329
Ronald Oussoren3075e162006-07-25 20:28:55 +0000330- Bug #1517990: IDLE keybindings on MacOS X now work correctly
331
332- Bug #1517996: IDLE now longer shows the default Tk menu when a
333 path browser, class browser or debugger is the frontmost window on MacOS X
334
Barry Warsaw00decd72006-07-27 23:43:15 +0000335- Patch #1520294: Support for getset and member descriptors in types.py,
336 inspect.py, and pydoc.py. Specifically, this allows for querying the type
337 of an object against these built-in types and more importantly, for getting
338 their docstrings printed in the interactive interpreter's help() function.

343
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000344- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
345 a socket operation on a socket with a timeout, the exception will be
346 caught correctly. Previously, the exception was not caught.
347
Thomas Heller1393d6a2006-07-28 21:43:20 +0000348- Patch #1529514: The _ctypes extension is now compiled on more
349 openbsd target platforms.
350
Tim Peters9cab5932006-07-28 00:30:00 +0000351- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
352 a memory leak, affecting pickles and deep copies.
353
Tim Petersbc24eee2006-07-27 01:14:53 +0000354- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

358
Thomas Hellerce049a02006-07-14 17:51:14 +0000359- Patch #1521817: Index range checking on ctypes arrays containing
360 exactly one element enabled again. This allows iterating over these
361 arrays, without the need to check the array size before.
362
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000363- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000364 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000365 /dev/null in certain cases; this is now fixed.
366
Thomas Heller47d7a062006-07-12 08:43:47 +0000367- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
368 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000369
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000370- Because of a misspelled preprocessor symbol, ctypes was always
371 compiled without thread support; this is now fixed.
372
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000373- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
374 methods now allow their database parameter to be None as the
375 sleepycat API allows.
376
Matt Flemingec926502006-07-28 11:27:27 +0000377- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
378 bluetooth API compared with Linux and FreeBSD.
379
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000380Tests
381-----
382
383- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
384 how long the test file should take to play. Now accepts taking 2.93 secs
385 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
386
Georg Brandl4793aa32006-07-28 18:31:39 +0000387- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
388 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
389 run via ``regrtest.py``. Now they do.

398
399- PythonLauncher now works correctly when the path to the script contains
400 characters that are treated specially by the shell (such as quotes).
401
402- Bug #1527397: PythonLauncher now launches scripts with the working directory
403 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000404 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000405 expect.

414-----------------
415
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000416- Bug #1441486: The literal representation of -(sys.maxint - 1)
417 again evaluates to a int object, not a long.
418
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000419- Bug #1501934: The scope of global variables that are locally assigned
420 using augmented assignment is now correctly determined.
421
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000422- Bug #927248: Recursive method-wrapper objects can now safely
423 be released.
424
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000425- Bug #1417699: Reject locale-specific decimal point in float()
426 and atof().
427
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000428- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
429 omit a default "error" argument for NULL pointer. This allows
430 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000431
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000432- Bug #1519018: 'as' is now validated properly in import statements.
433
Neal Norwitz28746ab2006-07-09 22:14:42 +0000434- On 64 bit systems, int literals that use less than 64 bits are
435 now ints rather than longs.
436
Neal Norwitzed657552006-07-10 00:04:44 +0000437- Bug #1512814, Fix incorrect lineno's when code at module scope
438 started after line 256.
439
Tim Peters32a83612006-07-10 21:08:24 +0000440- New function ``sys._current_frames()`` returns a dict mapping thread
441 id to topmost thread stack frame. This is for expert use, and is
442 especially useful for debugging application deadlocks. The functionality
443 was previously available in Fazal Majid's ``threadframe`` extension
444 module, but it wasn't possible to do this in a wholly threadsafe way from
445 an extension.

462
Thomas Woutersadd19112006-07-05 11:03:49 +0000463- string.Template() now correctly handles tuple-values. Previously,
464 multi-value tuples would raise an exception and single-value tuples would
465 be treated as the value they contain, instead.
466
Martin v. Löwisede77f52006-07-03 13:01:35 +0000467- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

483 socket again, which then gets closed as it becomes unreferenced.
484
Fred Drake10497c82006-06-29 02:57:48 +0000485- Bug #1504333: Make sgmllib support angle brackets in quoted

492
Brett Cannon53ab5b72006-06-22 16:49:14 +0000493- Bug #1510580: The 'warnings' module improperly required that a Warning
494 category be either a types.ClassType and a subclass of Warning. The proper
495 check is just that it is a subclass with Warning as the documentation states.
496
Georg Brandlad29e632006-06-21 17:45:17 +0000497- The compiler module now correctly compiles the new try-except-finally
498 statement (bug #1509132).
499
Neal Norwitz60373cd2006-06-22 06:30:50 +0000500- The wsgiref package is now installed properly on Unix.
501
Vinay Sajip28e57612006-07-01 10:45:20 +0000502- A bug was fixed in logging.config.fileConfig() which caused a crash on
503 shutdown when fileConfig() was called multiple times.
504
Gerhard Häring762fbd32006-07-02 17:48:30 +0000505- The sqlite3 module did cut off data from the SQLite database at the first
506 null character before sending it to a custom converter. This has been fixed
507 now.

Tim Peters112aad32006-07-19 00:03:19 +0000512- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
513 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
514 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000515
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000516- Assigning None to pointer type fields in ctypes structures possible
517 overwrote the wrong fields, this is fixed now.
518
519- Fixed a segfault in _ctypes when ctypes.wintypes were imported
520 on non-Windows platforms.
521
522- Bug #1518190: The ctypes.c_void_p constructor now accepts any
523 integer or long, without range checking.
524
525- Patch #1517790: It is now possible to use custom objects in the ctypes
526 foreign function argtypes sequence as long as they provide a from_param
527 method, no longer is it required that the object is a ctypes type.
528
529- The '_ctypes' extension module now works when Python is configured
530 with the --without-threads option.
531
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000532- Bug #1513646: os.access on Windows now correctly determines write
533 access, again.
534
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000535- Bug #1512695: cPickle.loads could crash if it was interrupted with

547
Tim Peters32a83612006-07-10 21:08:24 +0000548- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000549 Previously, the slight difference could cause compilation errors of the
550 'zlib' module on systems with more than one version of zlib.
551
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000552- The MSI compileall step was fixed to also support a TARGETDIR

585
Georg Brandla56b9152006-06-19 06:35:54 +0000586- Patch #1507676: Error messages returned by invalid abstract object operations
587 (such as iterating over an integer) have been improved and now include the
588 type of the offending object to help with debugging.
589
Brett Cannonea3912b2006-06-13 21:46:41 +0000590- Bug #992017: A classic class that defined a __coerce__() method that returned
591 its arguments swapped would infinitely recurse and segfault the interpreter.
592
Neal Norwitz909eb122006-06-12 02:13:21 +0000593- Fix the socket tests so they can be run concurrently.
594
Neal Norwitzb9845e72006-06-12 02:11:18 +0000595- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000596 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.

Brett Cannon22565aa2006-06-09 22:31:23 +0000598- Bug #532646: object.__call__() will continue looking for the __call__
599 attribute on objects until one without one is found. This leads to recursion
600 when you take a class and set its __call__ attribute to an instance of the
601 class. Originally fixed for classic classes, but this fix is for new-style.
602 Removes the infinite_rec_3 crasher.
603
Georg Brandl24250812006-06-09 18:45:48 +0000604- The string and unicode methods startswith() and endswith() now accept
605 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
606
Brett Cannonde3b0522006-06-08 17:00:45 +0000607- Buffer objects, at the C level, never used the char buffer
608 implementation even when the char buffer for the wrapped object was
609 explicitly requested (originally returned the read or write buffer).
610 Now a TypeError is raised if the char buffer is not present but is
611 requested.
612
Georg Brandlddbaa662006-06-04 21:56:52 +0000613- Patch #1346214: Statements like "if 0: suite" are now again optimized
614 away like they were in Python 2.4.
615
Georg Brandlb7c8f542006-05-27 12:30:25 +0000616- Builtin exceptions are now full-blown new-style classes instead of
617 instances pretending to be classes, which speeds up exception handling
618 by about 80% in comparison to 2.5a2.
619
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000620- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
621 Unicode 4.1.
622
Georg Brandlf4ef1162006-05-26 18:03:31 +0000623- Patch #921466: sys.path_importer_cache is now used to cache valid and
624 invalid file paths for the built-in import machinery which leads to
625 fewer open calls on startup.
626
Tim Peters696cf432006-05-24 21:10:40 +0000627- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
628 of-2 bases. The largest speedup is for inputs with about 1000 decimal
629 digits. Conversion from non-power-of-2 bases remains quadratic-time in
630 the number of input digits (it was and remains linear-time for bases
631 2, 4, 8, 16 and 32).
632
Tim Petersb713ec22006-05-23 18:45:30 +0000633- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
634 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
635 an integer close to ``sys.maxint``. This was repaired by patch
636 #1335972, which also gives a nice speedup.
637
Richard Jonescebbefc2006-05-23 18:28:17 +0000638- Patch #1337051: reduced size of frame objects.
639
640- PyErr_NewException now accepts a tuple of base classes as its
641 "base" parameter.
642
Richard Jones7c88dcc2006-05-23 10:37:38 +0000643- Patch #876206: function call speedup by retaining allocated frame
644 objects.
645
Georg Brandl7b90e162006-05-18 07:01:27 +0000646- Bug #1462152: file() now checks more thoroughly for invalid mode
647 strings and removes a possible "U" before passing the mode to the
648 C library function.
649
Neal Norwitz1004a532006-05-15 07:17:23 +0000650- Patch #1488312, Fix memory alignment problem on SPARC in unicode
651
Neal Norwitz373f0a72006-05-15 07:04:36 +0000652- Bug #1487966: Fix SystemError with conditional expression in assignment
653
Martin v. Löwis879768d2006-05-11 13:28:43 +0000654- WindowsError now has two error code attributes: errno, which carries
655 the error values from errno.h, and winerror, which carries the error
656 values from winerror.h. Previous versions put the winerror.h values
657 (from GetLastError()) into the errno attribute.
658
Martin v. Löwis77736712006-05-04 05:51:03 +0000659- Patch #1475845: Raise IndentationError for unexpected indent.
660
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000661- Patch #1479181: split open() and file() from being aliases for each other.
662
Tim Peters44bd9862006-06-01 13:49:23 +0000663- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
664 methods were always silently ignored by dictionaries when comparing keys.
665 They are now passed through (except when using the C API function
666 ``PyDict_GetItem()``, whose semantics did not change).
667
668- Bug #1456209: In some obscure cases it was possible for a class with a
669 custom ``__eq__()`` method to confuse dict internals when class instances
670 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
671 No, you don't have any code that did this ;-)

674-----------------
675
Trent Mick960a3f82006-06-28 20:30:41 +0000676- Bug #1295808: expat symbols should be namespaced in pyexpat
677
678- Patch #1462338: Upgrade pyexpat to expat 2.0.0
679
Brett Cannon6ee7d012006-06-08 16:23:04 +0000680- Change binascii.hexlify to accept a read-only buffer instead of only a char
681 buffer and actually follow its documentation.
682
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000683- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
684
Nick Coghlanc649ec52006-05-29 12:43:05 +0000685- Patch #1478788 (modified version): The functional extension module has
686 been renamed to _functools and a functools Python wrapper module added.
687 This provides a home for additional function related utilities that are
688 not specifically about functional programming. See PEP 309.
689
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000690- Patch #1493701: performance enhancements for struct module.
691
Georg Brandl378d5922006-05-17 14:26:50 +0000692- Patch #1490224: time.altzone is now set correctly on Cygwin.
693
Georg Brandl8d3342b2006-05-16 07:38:27 +0000694- Patch #1435422: zlib's compress and decompress objects now have a
695 copy() method.
696
Andrew MacIntyre92913322006-06-13 15:04:24 +0000697- Patch #1454481: thread stack size is now tunable at runtime for thread
698 enabled builds on Windows and systems with Posix threads support.
699
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000700- On Win32, os.listdir now supports arbitrarily-long Unicode path names
701 (up to the system limit of 32K characters).
702
703- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
704 As a result, these functions now raise WindowsError instead of OSError.
705
Tim Peters7a822da2006-05-25 21:50:17 +0000706- ``time.clock()`` on Win64 should use the high-performance Windows
707 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
708 Windows platforms).
709
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000710- Calling Tk_Init twice is refused if the first call failed as that
711 may deadlock.
712
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000713- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
714 accept it without potentially using an uninitialized pointer.
715
716- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
717 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
718 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000719
Gregory P. Smith372b5832006-06-05 18:48:21 +0000720- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000721 [pybsddb project SF patch number 1466734]
722
Gregory P. Smith372b5832006-06-05 18:48:21 +0000723- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
724 parameter is supplied. [SF pybsddb bug #1477863]
725
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000726- bsddb: the __len__ method of a DB object has been fixed to return correct
727 results. It could previously incorrectly return 0 in some cases.
728 Fixes SF bug 1493322 (pybsddb bug 1184012).
729
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000730- bsddb: the bsddb.dbtables Modify method now raises the proper error and
731 aborts the db transaction safely when a modifier callback fails.
732 Fixes SF python patch/bug #1408584.
733
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000734- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000735 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000736 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
737 database calls that would previously deadlock. [SF python bug #775414]
738
Vinay Sajip28e57612006-07-01 10:45:20 +0000739- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000740
Walter Dörwald4994d952006-06-19 08:07:50 +0000741- Patch #1506645: add Python wrappers for the curses functions
742 is_term_resized, resize_term and resizeterm.

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000747- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
748 functions.
749
Martin v. Löwis3798da02006-06-17 18:44:27 +0000750- Patch #812986: Update turtle output even if not tracing.
751
Vinay Sajip28e57612006-07-01 10:45:20 +0000752- Patch #1494750: Destroy master after deleting children in

754
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000755- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
756
Martin v. Löwis337487e2006-06-17 09:15:14 +0000757- Patch #763580: Add name and value arguments to Tkinter variable
758 classes.
759
Georg Brandl83cc0d02006-06-14 08:50:03 +0000760- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
761 mime.types file for determining MIME types.
762
Georg Brandl2605ca82006-06-14 06:08:31 +0000763- Bug #1339007: Shelf objects now don't raise an exception in their
764 __del__ method when initialization failed.
765
Martin v. Löwisd8251432006-06-14 05:21:04 +0000766- Patch #1455898: The MBCS codec now supports the incremental mode for
767 double-byte encodings.
768
Tim Peters43898b42006-06-14 04:09:25 +0000769- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
770 guarantee that adjacent triples in the return list always describe
771 non-adjacent blocks. Previously, a pair of matching blocks could end
772 up being described by multiple adjacent triples that formed a partition
773 of the matching pair.
774
Greg Ward0e0c9f42006-06-11 16:24:11 +0000775- Bug #1498146: fix optparse to handle Unicode strings in option help,
776 description, and epilog.
777
Greg Wardd1c797e2006-06-11 14:42:41 +0000778- Bug #1366250: minor optparse documentation error.
779
Greg Ward7f547402006-06-11 00:40:49 +0000780- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
781 clarify docs.
782
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000783- The wsgiref package has been added to the standard library.
784
Nick Coghlan676725d2006-06-08 13:54:49 +0000785- The functions update_wrapper() and wraps() have been added to the functools
786 module. These make it easier to copy relevant metadata from the original
787 function when writing wrapper functions.
788
Tim Petersd6a9eef2006-06-05 01:48:21 +0000789- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
790 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000791
Martin v. Löwis3f767792006-06-04 19:36:28 +0000792- Patch #1359618: Speed up charmap encoder by using a trie structure
793 for lookup.
794
Tim Petersd609b1a2006-06-02 23:22:51 +0000795- The functions in the ``pprint`` module now sort dictionaries by key
796 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
797 if and only if its display required more than one line, although that
798 wasn't documented. The new behavior increases predictability; e.g.,
799 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
800
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000801- Patch #1497027: try HTTP digest auth before basic auth in urllib2
802 (thanks for J. J. Lee).
803
Georg Brandl2b330372006-05-28 20:23:12 +0000804- Patch #1496206: improve urllib2 handling of passwords with respect to
805 default HTTP and HTTPS ports.
806
George Yoshidaf3c65de2006-05-28 16:39:09 +0000807- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
808
Bob Ippolito7298f272006-05-23 18:43:47 +0000809- Patch #1281707: speed up gzip.readline.
810
Georg Brandlb89316f2006-05-17 15:51:16 +0000811- Patch #1180296: Two new functions were added to the locale module:
812 format_string() to get the effect of "format % items" but locale-aware,
813 and currency() to format a monetary number with currency sign.
814
Georg Brandle3a25832006-05-17 14:56:04 +0000815- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
816 and several features added, such as speed and geometry control.
817
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000818- Patch #1488881: add support for external file objects in bz2 compressed
819 tarfiles.
820
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000821- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
822 stdout arguments, making it possible to redirect input and output
823 for remote debugging.
824
825- Patch #1484695: Update the tarfile module to version 0.8. This fixes
826 a couple of issues, notably handling of long file names using the
827 GNU LONGNAME extension.
828
829- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
830 new flag when ``name`` is already the name of an option flag.
831
832- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
833 package.
834
835- Patch #1472854: make the rlcompleter.Completer class usable on non-
836 UNIX platforms.
837
838- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
839
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000840- Bug #1472827: correctly escape newlines and tabs in attribute values in

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000871What's New in Python 2.5 alpha 2?
872=================================
873
874*Release date: 27-APR-2006*
875
876Core and builtins
877-----------------
878
Thomas Heller1b046642006-04-18 18:51:06 +0000879- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
880 by converting these apis from macros into exported functions again:
881
882 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
883 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
884 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
885 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
886 PyRun_String Py_CompileString
887
Martin v. Löwis45294a92006-04-18 06:24:08 +0000888- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
889
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000890- All uses of PyStructSequence_InitType have been changed to initialize
891 the type objects only once, even if the interpreter is initialized
892 multiple times.
893
Neal Norwitz61546162006-04-14 05:20:28 +0000894- Bug #1454485, array.array('u') could crash the interpreter. This was
895 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
896 to unicode when it didn't make sense. 'u#' now requires a unicode string.
897
898- Py_UNICODE is unsigned. It was always documented as unsigned, but
899 due to a bug had a signed value in previous versions.
900
Tim Peters3a5e8b12006-04-11 01:44:07 +0000901- Patch #837242: ``id()`` of any Python object always gives a positive
902 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
903 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000904 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000905 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000906
Tim Peters3a5e8b12006-04-11 01:44:07 +0000907 def __hash__(self):
908 return id(self) # WRONG
909
910 because a hash result must be a (short) Python int but it was always
911 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000912 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000913 was always usable as a hash value before this patch. That's no longer
914 necessarily so.
915
916- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000917 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000918 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000919 #1454844)
920
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000921- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
922 involving generators that have paused outside of any ``try`` or ``with``
923 blocks. (In 2.5a1, a paused generator that was part of a reference
924 cycle could not be garbage collected, regardless of whether it was
925 paused in a ``try`` or ``with`` block.)

942 a temporary db (file=None) with the 'n' flag to truncate on open.
943
944- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
945 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000946

951-------
952
Peter Astrand7d1d4362006-07-14 14:04:45 +0000953- Bug #1223937: subprocess.CalledProcessError reports the exit status
954 of the process using the returncode attribute, instead of
955 abusing errno.
956
Tim Peters711bf302006-04-25 03:31:36 +0000957- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
958 a doctest to be skipped (the code is not run, and the expected output
959 or exception is ignored).
960
Nick Coghlanda2268f2006-04-24 04:37:15 +0000961- Fixed contextlib.nested to cope with exceptions being raised and
962 caught inside exit handlers.
963
Greg Wardab05edc2006-04-23 03:47:58 +0000964- Updated optparse module to Optik 1.5.1 (allow numeric constants in
965 hex, octal, or binary; add ``append_const`` action; keep going if
966 gettext cannot be imported; added ``OptionParser.destroy()`` method;
967 added ``epilog`` for better help generation).
968
Tim Peters21fbd572006-04-21 21:18:10 +0000969- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
970 called from a thread spawned as a side effect of importing a module.
971
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000972- The pydoc module now supports documenting packages contained in
973 .zip or .egg files.
974
975- The pkgutil module now has several new utility functions, such
976 as ``walk_packages()`` to support working with packages that are either
977 in the filesystem or zip files.
978
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000979- The mailbox module can now modify and delete messages from
980 mailboxes, in addition to simply reading them. Thanks to Gregory
981 K. Johnson for writing the code, and to the 2005 Google Summer of
982 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000983

994 Windows. Bug #1469163.
995
Phillip J. Eby47032112006-04-11 01:07:43 +0000996- The warnings, linecache, inspect, traceback, site, and doctest modules
997 were updated to work correctly with modules imported from zipfiles or
998 via other PEP 302 __loader__ objects.

Skip Montanaro262fb922006-04-21 02:31:07 +00001007- The pstats.Stats class accepts an optional stream keyword argument to
1008 direct output to an alternate file-like object.
1009
Anthony Baxter51bcb682006-04-05 14:51:42 +00001010Build
1011-----
1012
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001013- The Makefile now has a reindent target, which runs reindent.py on
1014 the library.
1015
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001016- Patch #1470875: Building Python with MS Free Compiler
1017

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001019
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001020- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1021 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001022 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001023 CXX from --with-cxx-main, see description in README.
1024
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001025- Patch #1429775: Link extension modules with the shared libpython.
1026
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001027- Fixed a libffi build problem on MIPS systems.
1028
Tim Peters8931ff12006-05-13 23:28:20 +00001029- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1030 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1031 and "%zu" for unsigned integers of type ``size_t``.
1032
Anthony Baxter51bcb682006-04-05 14:51:42 +00001033Tests
1034-----
1035
Nick Coghlanda2268f2006-04-24 04:37:15 +00001036- test_contextlib now checks contextlib.nested can cope with exceptions
1037 being raised and caught inside exit handlers.
1038
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001039- test_cmd_line now checks operation of the -m and -c command switches
1040
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001041- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1042 it separately and by hand. It also wasn't cleaning up its changes to
1043 the current Decimal context.
1044
Thomas Woutersabd08882006-04-26 15:53:30 +00001045- regrtest.py now has a -M option to run tests that test the new limits of
1046 containers, on 64-bit architectures. Running these tests is only sensible
1047 on 64-bit machines with more than two gigabytes of memory. The argument
1048 passed is the maximum amount of memory for the tests to use.

1057-------------
1058
Tim Petersb06d28c2006-05-12 01:57:59 +00001059- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1060
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001061- PEP 343: Added Context Types section to the library reference
1062 and attempted to bring other PEP 343 related documentation into
1063 line with the implementation and/or python-dev discussions.
1064
Tim Peters8dc73d22006-04-24 02:03:16 +00001065- Bug #1337990: clarified that ``doctest`` does not support examples
1066 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001069What's New in Python 2.5 alpha 1?
1070=================================
1071
Anthony Baxterebed3f62006-04-03 15:03:44 +00001072*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001073
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001074Core and builtins
1075-----------------
1076
Nick Coghlan43832302006-04-23 17:04:07 +00001077- PEP 338: -m command line switch now delegates to runpy.run_module
1078 allowing it to support modules in packages and zipfiles
1079
Martin v. Löwisc661b882006-04-20 04:54:23 +00001080- On Windows, .DLL is not an accepted file name extension for
1081 extension modules anymore; extensions are only found if they
1082 end in .PYD.
1083
Martin v. Löwisea62d252006-04-03 10:56:49 +00001084- Bug #1421664: sys.stderr.encoding is now set to the same value as
1085 sys.stdout.encoding.
1086
Neal Norwitz92e212f2006-04-03 04:48:37 +00001087- __import__ accepts keyword arguments.
1088
Georg Brandlccadf842006-03-31 18:54:53 +00001089- Patch #1460496: round() now accepts keyword arguments.
1090
Anthony Baxter262c00a2006-03-30 10:53:17 +00001091- Fixed bug #1459029 - unicode reprs were double-escaped.
1092
Hye-Shik Changd478f342006-03-23 12:32:36 +00001093- Patch #1396919: The system scope threads are reenabled on FreeBSD
1094 5.4 and later versions.
1095
Neal Norwitze98ccf62006-03-23 05:39:47 +00001096- Bug #1115379: Compiling a Unicode string with an encoding declaration
1097 now gives a SyntaxError.
1098
Georg Brandlabd1ff82006-03-18 07:59:59 +00001099- Previously, Python code had no easy way to access the contents of a
1100 cell object. Now, a ``cell_contents`` attribute has been added
1101 (closes patch #1170323).
1102
Tim Peterscf79aac2006-03-16 01:14:46 +00001103- Patch #1123430: Python's small-object allocator now returns an arena to
1104 the system ``free()`` when all memory within an arena becomes unused
1105 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1106 freed. Some applications will see a drop in virtual memory size now,
1107 especially long-running applications that, from time to time, temporarily
1108 use a large number of small objects. Note that when Python returns an
1109 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001110 platform C library will in turn return that memory to the operating system.
1111 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001112 appears to be effective at least on Microsoft C and gcc-based systems.
1113 Thanks to Evan Jones for hard work and patience.
1114
Georg Brandl533ff6f2006-03-08 18:09:27 +00001115- Patch #1434038: property() now uses the getter's docstring if there is
1116 no "doc" argument given. This makes it possible to legitimately use
1117 property() as a decorator to produce a read-only property.
1118
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001119- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1120 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1121 of requiring an int or long in slicing and a few other contexts, enabling
1122 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1123
Neal Norwitz995acdf2006-03-07 05:01:00 +00001124- Fixed various bugs reported by Coverity's Prevent tool.
1125
Brett Cannonbf364092006-03-01 04:25:17 +00001126- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1127 new exception base class, BaseException, which has a new message attribute.
1128 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1129 Raising a string exception now raises a DeprecationWarning.
1130
Thomas Woutersfb609f42006-02-28 16:37:25 +00001131- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1132 explicitly relative, using 'from .module import name' to mean 'from the same
1133 package as this module is in. Imports without dots still default to the
1134 old relative-then-absolute, unless 'from __future__ import
1135 absolute_import' is used.
1136
Brett Cannona7446e32006-02-27 23:39:10 +00001137- Properly check if 'warnings' raises an exception (usually when a filter set
1138 to "error" is triggered) when raising a warning for raising string
1139 exceptions.
1140
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001141- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001142 The name was removed from Include/code.h.
1143
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001144- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001145
Guido van Rossum1968ad32006-02-25 22:38:04 +00001146- Patch 1433928:
1147 - The copy module now "copies" function objects (as atomic objects).
1148 - dict.__getitem__ now looks for a __missing__ hook before raising
1149 KeyError.
1150
Tim Peters84ef21c2006-02-28 20:39:06 +00001151- PEP 343: with statement implemented. Needs ``from __future__ import
1152 with_statement``. Use of 'with' as a variable will generate a warning.
1153 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001154 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001155 The following objects have __context__ methods:
1156 - The built-in file type.
1157 - The thread.LockType type.
1158 - The following types defined by the threading module:
1159 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1160 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001161
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001162- Fix the encodings package codec search function to only search
1163 inside its own package. Fixes problem reported in patch #1433198.
1164
1165 Note: Codec packages should implement and register their own
1166 codec search function. PEP 100 has the details.
1167
Tim Peters9ea89d22006-06-04 03:26:02 +00001168- PEP 353: Using ``Py_ssize_t`` as the index type.
1169
1170- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1171 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1172 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1173 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1174 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001175
Neal Norwitzfc76d632006-01-10 06:03:13 +00001176- Patch #1400181, fix unicode string formatting to not use the locale.
1177 This is how string objects work. u'%f' could use , instead of .
1178 for the decimal point. Now both strings and unicode always use periods.
1179
Neal Norwitz671b9e32006-01-09 07:07:12 +00001180- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1181 configure would break checking curses.h.
1182
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001183- Bug #959576: The pwd module is now builtin. This allows Python to be
1184 built on UNIX platforms without $HOME set.
1185
Neal Norwitzc10978f2005-12-19 06:07:16 +00001186- Bug #1072182, fix some potential problems if characters are signed.
1187
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001188- Bug #889500, fix line number on SyntaxWarning for global declarations.
1189
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001190- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1191
Neal Norwitze7214a12005-12-18 05:03:17 +00001192- Support for converting hex strings to floats no longer works.
1193 This was not portable. float('0x3') now raises a ValueError.
1194
Barry Warsaw2a38a862005-12-18 01:27:35 +00001195- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001196 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001197 is now displayed in interactive prompt banner.
1198
Georg Brandlfa166682005-12-17 21:45:17 +00001199- Implementation of PEP 341 - Unification of try/except and try/finally.
1200 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001201 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001202
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001203- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1204 now encodes backslash correctly.
1205
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001206- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1207
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001208- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001209 and long longs.
1210
Neal Norwitz67715f02005-11-09 06:59:35 +00001211- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001212 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001213 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001214
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001215- Replaced most Unicode charmap codecs with new ones using the
1216 new Unicode translate string feature in the builtin charmap
1217 codec; the codecs were created from the mapping tables available
1218 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1219 encodings now include a mapping for the Apple logo)
1220
Tim Peterse3547fd2005-12-16 23:13:57 +00001221- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001222
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001223- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001224
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001225- A new AST parser implementation was completed. The abstract
1226 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001227 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001228
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001229- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001230 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1231
Neal Norwitz708e51a2005-10-03 04:48:15 +00001232- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1233
Neal Norwitz11bd1192005-10-03 00:54:56 +00001234- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1235 Provide a warning when a directory is passed on the command line.
1236
Neal Norwitz40d37812005-10-02 01:48:49 +00001237- Fix segfault with invalid coding.
1238
1239- SF bug #772896: unknown encoding results in MemoryError.
1240
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001241- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001242 supported a __len__() method which evaluated to False when the iterator
1243 was empty.
1244
Guido van Rossum630db602005-09-20 18:49:54 +00001245- On 64-bit platforms, when __len__() returns a value that cannot be
1246 represented as a C int, raise OverflowError.
1247
Skip Montanarof8948ca2005-09-19 03:54:46 +00001248- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001249 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001250
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001251- SF bug #893549: parsing keyword arguments was broken with a few format
1252 codes.
1253
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001254- Changes donated by Elemental Security to make it work on AIX 5.3
1255 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1256 bug #105470: test_pwd fails on 64bit system (Opteron).
1257
Guido van Rossum539c6622005-09-14 17:49:54 +00001258- Changes donated by Elemental Security to make it work on HP-UX 11 on
1259 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1260
Georg Brandl4550b8d2005-08-26 06:43:52 +00001261- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001262 (fixes bug #1119418).
1263
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001264- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1265
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001266- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1267 exceptions that cause a function to exit.
1268
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001269- The implementation of set() and frozenset() was revised to use its
1270 own internal data structure. Memory consumption is reduced by 1/3
1271 and there are modest speed-ups as well. The API is unchanged.
1272
Tim Petersde7990b2005-07-17 23:45:23 +00001273- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1274
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001275- SF bug #1229429: PyObject_CallMethod failed to decrement some
1276 reference counts in some error exit cases.
1277
Tim Petersecc6e6a2005-07-10 22:30:55 +00001278- SF bug #1185883: Python's small-object memory allocator took over
1279 a block managed by the platform C library whenever a realloc specified
1280 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001281 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001282 portable way to copy data from the C-managed block into Python's
1283 small-object space without risking a memory fault. Python's small-object
1284 realloc now leaves such blocks under the control of the platform C
1285 realloc.
1286
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001287- SF bug #1232517: An overflow error was not detected properly when
1288 attempting to convert a large float to an int in os.utime().
1289
Raymond Hettinger3296e692005-06-29 23:29:56 +00001290- SF bug #1224347: hex longs now print with lowercase letters just
1291 like their int counterparts.
1292
Michael W. Hudson188d4362005-06-20 16:52:57 +00001293- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1294 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1295 interpreter states; back out that fix and do a better job (see
1296 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1297 for a longer write-up of the problem).
1298
Michael W. Hudsondf888462005-06-03 14:41:55 +00001299- SF patch #1180995: marshal now uses a binary format by default when
1300 serializing floats.
1301
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001302- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1303 the routines that promise to produce IEEE 754 binary representations
1304 of floats now simply copy bytes around.
1305
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001306- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1307 278.
1308
Brett Cannonc3647ac2005-04-26 03:45:26 +00001309- patch #1109424: int, long, float, complex, and unicode now check for the
1310 proper magic slot for type conversions when subclassed. Previously the
1311 magic slot was ignored during conversion. Semantics now match the way
1312 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001313 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001314 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001315 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001316
Barry Warsawc8d907c2005-04-19 23:43:40 +00001317- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1318 NULL, now raise an AttributeError when attempting to set or delete the
1319 attribute. Previously a TypeError was raised, but this was inconsistent
1320 with the equivalent pure-Python implementation.
1321
Michael W. Hudson774479c2005-04-18 08:46:17 +00001322- It is now safe to call PyGILState_Release() before
1323 PyEval_InitThreads() (note that if there is reason to believe there
1324 are multiple threads around you still must call PyEval_InitThreads()
1325 before using the Python API; this fix is for extension modules that
1326 have no way of knowing if Python is multi-threaded yet).
1327
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001328- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1329 disabled caused a crash.
1330
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001331- Bug #1165306: instancemethod_new allowed the creation of a method
1332 with im_class == im_self == NULL, which caused a crash when called.
1333
Tim Petersecc6e6a2005-07-10 22:30:55 +00001334- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001335 fixes the crash seen in bug #1165761
1336
Raymond Hettinger96229b12005-03-11 06:49:40 +00001337- Added two new builtins, any() and all().
1338
Brett Cannon409d8f22005-03-05 06:47:57 +00001339- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001340 (e.g., ``class C(): pass`` is no longer a syntax error).
1341 Patch #1176012 added support to the 'parser' module and 'compiler' package
1342 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001343
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001344- Patch #1115086: Support PY_LONGLONG in structmember.
1345
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001346- Bug #1155938: new style classes did not check that __init__() was
1347 returning None.
1348
Tim Petersecc6e6a2005-07-10 22:30:55 +00001349- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001350 ('\') with a specific error message.
1351
Martin v. Löwisff232d72005-03-03 09:24:38 +00001352- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1353
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001354- Bug #1124295: the __name__ attribute of file objects was
1355 inadvertently made inaccessible in restricted mode.
1356
Tim Petersecc6e6a2005-07-10 22:30:55 +00001357- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001358 an ferror() call.
1359
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001360- min() and max() now support key= arguments with the same meaning as in
1361 list.sort().
1362
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001363- The peephole optimizer now performs simple constant folding in expressions:
1364 (2+3) --> (5).
1365
Raymond Hettingera422c342005-01-11 03:03:27 +00001366- set and frozenset objects can now be marshalled. SF #1098985.
1367
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001368- Bug #1077106: Poor argument checking could cause memory corruption
1369 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001370
Jeremy Hyltonab630502005-02-04 18:44:06 +00001371- The parser did not complain about future statements in illegal
1372 positions. It once again reports a syntax error if a future
1373 statement occurs after anything other than a doc string.
1374
Neil Schemenauercf52c072005-08-12 17:34:58 +00001375- Change the %s format specifier for str objects so that it returns a
1376 unicode instance if the argument is not an instance of basestring and
1377 calling __str__ on the argument returns a unicode instance.
1378
Tim Petersf4e69282006-02-27 17:15:31 +00001379- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1380 current thread state when the auto-GIL-state machinery knows about
1381 it (since the thread state is being deleted, continuing to remember it
1382 can't help, but can hurt if another thread happens to get created with
1383 the same thread id).
1384
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001385Extension Modules
1386-----------------
1387

Tim Petersc9d78aa2006-03-26 23:27:58 +00001400 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001401 util, whatsound, whrandom, zmod
1402
1403- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1404
1405- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001406 is deprecated. The undocumented re.engine variable no longer exists.
1407
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001408- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1409 SS2 (single-shift 2) escape sequences correctly.
1410
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001411- The unicodedata module was updated to the 4.1 version of the Unicode
1412 database. The 3.2 version is still available as unicodedata.db_3_2_0
1413 for applications that require this specific version (such as IDNA).
1414
Neal Norwitzb62c4332006-03-04 18:35:47 +00001415- The timing module is no longer built by default. It was deprecated
1416 in PEP 4 in Python 2.0 or earlier.
1417
Guido van Rossum1968ad32006-02-25 22:38:04 +00001418- Patch 1433928: Added a new type, defaultdict, to the collections module.
1419 This uses the new __missing__ hook behavior added to dict (see above).
1420
Georg Brandldbd83392006-02-20 09:42:33 +00001421- Bug #854823: socketmodule now builds on Sun platforms even when
1422 INET_ADDRSTRLEN is not defined.
1423
Georg Brandlf4f44152006-02-18 22:29:33 +00001424- Patch #1393157: os.startfile() now has an optional argument to specify
1425 a "command verb" to invoke on the file.
1426
Neal Norwitz082b2df2006-02-07 07:04:46 +00001427- Bug #876637, prevent stack corruption when socket descriptor
1428 is larger than FD_SETSIZE.
1429
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001430- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1431 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1432 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1433
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001434- Patch #1422385: The nis module now supports access to domains other
1435 than the system default domain.
1436
Martin v. Löwis14694662006-02-03 12:54:16 +00001437- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1438 are reported, the limit on path name lengths is removed, and stat reports
1439 WindowsError now (instead of OSError).
1440
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001441- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

Michael W. Hudson8137bea2005-07-27 20:24:40 +00001515- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
1516 the request code argument, which results in more C-like behaviour
1517 for large or negative values.
1518
Tim Petersecc6e6a2005-07-10 22:30:55 +00001519- Bug #1234979: For the argument of thread.Lock.acquire, the Windows
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001520 implementation treated all integer values except 1 as false.
Georg Brandlaf410b52005-07-08 22:26:13 +00001521

1534
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00001535- operator.itemgetter() and operator.attrgetter() now support retrieving

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001559- the cPickle module no longer accepts the deprecated None option in the
1560 args tuple returned by __reduce__().
1561
Raymond Hettingerb2594052004-12-05 09:25:51 +00001562- itertools.islice() now accepts None for the start and step arguments.
1563 This allows islice() to work more readily with slices:
1564 islice(s.start, s.stop, s.step)
1565
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001566- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001575- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1576 been renamed to have only a single underscore prefix. This was done to
1577 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001578
Nick Coghlan43832302006-04-23 17:04:07 +00001579- PEP 338: new module runpy defines a run_module function to support
1580 executing modules which provide access to source code or a code object
1581 via the PEP 302 import mechanisms.
1582
Anthony Baxter93f5b932006-04-03 08:05:07 +00001583- The email module's parsedate_tz function now sets the daylight savings
1584 flag to -1 (unknown) since it can't tell from the date whether it should

1591 in attribute values.
1592
Anthony Baxterc51ee692006-04-01 00:57:31 +00001593- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001594 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001595 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001596 module will not be built.
1597
Tim Petersc17976e2006-04-01 00:26:53 +00001598- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1599 aren't officially supported here, and trying to use them will probably
1600 raise an exception some day. But dicts have been allowed, and "mostly
1601 worked", so support for them won't go away without warning.
1602
Georg Brandl338ef7d2006-03-31 18:42:16 +00001603- Bug #1445068: getpass.getpass() can now be given an explicit stream
1604 argument to specify where to write the prompt.
1605
Georg Brandl22ec80b2006-03-31 18:25:44 +00001606- Patch #1462313, bug #1443328: the pickle modules now can handle classes
1607 that have __private names in their __slots__.

1613
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001614- Queue.Queue objects now support .task_done() and .join() methods
1615 to make it easier to monitor when daemon threads have completed
1616 processing all enqueued tasks. Patch #1455676.
1617

1621
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001622- email 4.0 package now integrated. This is largely the same as the email 3.0
1623 package that was included in Python 2.3, except that PEP 8 module names are
1624 now used (e.g. mail.message instead of email.Message). The MIME classes
1625 have been moved to a subpackage (e.g. email.mime.text instead of
1626 email.MIMEText). The old names are still supported for now. Several
1627 deprecated Message methods have been removed and lots of bugs have been
1628 fixed. More details can be found in the email package documentation.
1629
Walter Dörwald40108c92006-03-27 08:15:44 +00001630- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1631 (a subclass of tuple) that provides incremental decoders and encoders
1632 (a way to use stateful codecs without the stream API). Python functions
1633 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1634 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1635 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001636
Walter Dörwald067db482006-03-15 22:17:27 +00001637- Patch #1359365: Calling next() on a closed StringIO.String object raises
1638 a ValueError instead of a StopIteration now (like file and cString.String do).
1639 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1640 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001641
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001642- A regrtest option -w was added to re-run failed tests in verbose mode.

1652
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001653- PEP 343: new module contextlib.py defines decorator @contextmanager
1654 and helpful context managers nested() and closing().
1655
Martin v. Löwis415ed932006-02-27 19:56:30 +00001656- The compiler package now supports future imports after the module docstring.
1657

Martin v. Löwis3e865952006-01-24 15:51:21 +00001690 specifications, raises IOErrors when proxies for unsupported protocols
1691 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00001714 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1715 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1716 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1717 Ronald L. Rivest offered this advice for Python:
1718
1719 "The consensus of researchers in this area (at least as
1720 expressed at the NIST Hash Function Workshop 10/31/05),
1721 is that SHA-256 is a good choice for the time being, but
1722 that research should continue, and other alternatives may
1723 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001724
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001725- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandlb9256022005-08-24 18:46:39 +00001771- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
1772 ContentTooShortException, when the actually downloaded size does not
1773 match the Content-Length header.
1774
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +00001775- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.

1778 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001779 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001780

1802 to W3C name (404 -> 'Not Found'). RFE #1216944.
1803
Georg Brandl9e43acf2005-07-04 17:16:07 +00001804- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1805 as this can cause problems with apps closing all file descriptors.

1818 Bug #1224621.
1819
Raymond Hettinger68c04532005-06-10 11:05:19 +00001820- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001821 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001822 the generate_tokens() function now accepts a callable argument that
1823 terminates by raising StopIteration.
1824
Georg Brandl9166e1a2005-06-04 09:20:03 +00001825- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1833 class at all.
1834
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001835- distutils.commands.upload was added to support uploading distribution
1836 files to PyPI.
1837
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001838- distutils.commands.register now encodes the data as UTF-8 before posting
1839 them to PyPI.
1840
Raymond Hettinger267b8682005-03-27 10:47:39 +00001841- decimal operator and comparison methods now return NotImplemented
1842 instead of raising a TypeError when interacting with other types. This
1843 allows other classes to implement __radd__ style methods and have them
1844 work as expected.
1845
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001846- Bug #1163325: Decimal infinities failed to hash. Attempting to
1847 hash a NaN raised an InvalidOperation instead of a TypeError.
1848
Tim Petersecc6e6a2005-07-10 22:30:55 +00001849- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1883
Guido van Rossumd0641422005-02-03 15:01:24 +00001884- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1885 disables recursive traversal through instance attributes, which can
1886 be exploited in various ways.
1887
Tim Peterse3547fd2005-12-16 23:13:57 +00001888- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001889 flags on the HTTP listening socket.
1890
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001891- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1892 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1893
Fred Drakefbdeaad2006-07-29 16:56:15 +00001894- Patches #893642, #1039083: add allow_none, encoding arguments to
1895 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001896
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001897- Bug #1110478: Revert os.environ.update to do putenv again.
1898
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001899- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1900
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001901- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1902
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001903- Enhancements to the csv module:
1904
1905 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001906 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001907 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001908 + Dialect parameter parsing has been re-implemented to improve error
1909 reporting.
1910 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1911 dictates.
1912 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001913 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001914 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001915 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1916 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001917 + reader now allows \r characters to be quoted (previously it only allowed
1918 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001919 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001920 + Dialect classes passed to the module are no longer instantiated by
1921 the module before being parsed (the former validation scheme required
1922 this, but the mechanism was unreliable).
1923 + The dialect registry now contains instances of the internal
1924 C-coded dialect type, rather than references to python objects.
1925 + the internal c-coded dialect type is now immutable.
1926 + register_dialect now accepts the same keyword dialect specifications
1927 as the reader and writer, allowing the user to register dialects
1928 without first creating a dialect class.
1929 + a configurable limit to the size of parsed fields has been added -
1930 previously, an unmatched quote character could result in the entire
1931 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001932 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001933 the parser field size limit (returning the former limit). The initial
1934 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001935 + A line_num attribute has been added to the reader object, which tracks
1936 the number of lines read from the source iterator. This is not
1937 the same as the number of records returned, as records can span
1938 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001939 + reader and writer objects were not being registered with the cyclic-GC.
1940 This has been fixed.
1941
Brett Cannone6539c42005-01-08 02:43:53 +00001942- _DummyThread objects in the threading module now delete self.__block that is
1943 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1944 lock primitives tend to be limited in number and thus should not be wasted on
1945 a _DummyThread object. Fixes bug #1089632.
1946
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001947- The imghdr module now detects Exif files.
1948
Raymond Hettinger6065d322004-12-20 23:51:53 +00001949- StringIO.truncate() now correctly adjusts the size attribute.
1950 (Bug #951915).
1951
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001952- locale.py now uses an updated locale alias table (built using
1953 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1954 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001955 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001956
Raymond Hettinger3557f422004-12-07 12:02:02 +00001957- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1958
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001959- the pickle module no longer accepts the deprecated None option in the
1960 args tuple returned by __reduce__().
1961
Brett Cannon84667c02004-12-07 03:25:18 +00001962- optparse now optionally imports gettext. This allows its use in setup.py.
1963
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001964- the pickle module no longer uses the deprecated bin parameter.
1965
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001966- the shelve module no longer uses the deprecated binary parameter.
1967
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001968- the pstats module no longer uses the deprecated ignore() method.
1969
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001970- the filecmp module no longer uses the deprecated use_statcache argument.
1971
Raymond Hettinger664347b2004-12-04 21:21:53 +00001972- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1973 extended or overridden by subclasses. Formerly, the subclassed method would
1974 be ignored by the rest of the module. (Bug #1078905).
1975
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001976- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001977 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001978
Walter Dörwald36733692004-12-22 12:50:50 +00001979- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1980 once when a size argument is given. This prevents a buffer overflow in the
1981 tokenizer with very long source lines.
1982
Barry Warsaw538561e2006-01-01 21:48:54 +00001983- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1984 immediately after creating the object, without any intervening
1985 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001986
Skip Montanaro05885812005-01-16 20:48:27 +00001987- The reconvert.quote function can now emit triple-quoted strings. The
1988 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001989
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001990- ``UserString.MutableString`` now supports negative indices in
1991 ``__setitem__`` and ``__delitem__``
1992
Greg Ward40407942005-03-05 02:53:17 +00001993- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1994 correctly.
1995
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001996- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1997 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1998 character even if the user has passed a size parameter to get a proper
1999 line ending. Remove the special handling of a "\r\n" that has been split
2000 between two lines.
2001
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002002- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2003 about illegal code points. The codec now supports PEP 293 style error
2004 handlers.
2005
Walter Dörwald78a78b02005-09-01 12:04:29 +00002006- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002007 from the input stream, so that the output is a byte string in the correct
2008 encoding instead of a unicode string.

Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002010- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2011 considering it exactly like a '*'.
2012
Walter Dörwald007f8df2005-10-09 19:42:27 +00002013- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2014 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002015
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002016- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2017
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002018- Patch #1413711: Certain patterns of differences were making difflib
2019 touch the recursion limit.
2020
Walter Dörwald58917a62006-03-31 15:26:22 +00002021- Bug #947906: An object oriented interface has been added to the calendar
2022 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002023 called as a script (e.g. via ``python -mcalendar``). Localized month and
2024 weekday names can be ouput (even if an exotic encoding is used) using
2025 special classes that use unicode.

2028-----
2029
Neal Norwitz602d3392006-03-31 08:21:40 +00002030- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2031 by using -mieee gcc option.
2032

2034
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002035- Build support for Win64-AMD64 was added.
2036
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002037- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2038
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002039- Patch #881820: look for openpty and forkpty also in libbsd.
2040
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002041- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2042 The zlib module is now builtin on Windows.
2043
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002044- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2045
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002046- Bug #1189330: configure did not correctly determine the necessary
2047 value of LINKCC if python was built with GCC 4.0.
2048
Trent Mick8321b422005-07-26 02:29:21 +00002049- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2050 vulnerability in zlib 1.2.1 and 1.2.2.
2051
Brett Cannon08cd5982005-04-24 22:26:38 +00002052- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2053 flags that change binary compatibility. Changes were also made to
2054 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002055 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002056
Bob Ippolitoed233462005-03-29 13:47:59 +00002057- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2058 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2059 no longer exists). This configure patch makes things right.
2060
Martin v. Löwise2713be2005-03-08 15:03:08 +00002061- Bug #1158607: Build with --disable-unicode again.
2062
Brett Cannon46d96232005-02-16 00:07:19 +00002063- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2064 defined. Discovered as a result of not being able to build on OS X.
2065
Brett Cannon516592f2004-12-07 00:42:59 +00002066- setup.py now uses the directories specified in LDFLAGS using the -L option
2067 and in CPPFLAGS using the -I option for adding library and include
2068 directories, respectively, for compiling extension modules against. This has
2069 led to the core being compiled using the values in CPPFLAGS. It also removes
2070 the need for the special-casing of both DarwinPorts and Fink for darwin since
2071 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2072 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2073 Fink, ``-I/opt/local/include`` for DarwinPorts).
2074
Brett Cannon43802422005-02-10 20:48:03 +00002075- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2076 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2077 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2078 Closes bug #1096244. Thanks Gregory Bond.

2081-----
2082
Tim Petersc9d78aa2006-03-26 23:27:58 +00002083- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2084 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2085 is obtained via the ``PyObject_`` family, it must be released via the
2086 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2087 always been officially true, but when Python's small-object allocator was
2088 introduced, an attempt was made to cater to a few extension modules
2089 discovered at the time that obtained memory via ``PyObject_New`` but
2090 released it via ``PyMem_DEL``. It's years later, and if such code still
2091 exists it will fail now (probably with segfaults, but calling wrong
2092 low-level memory management functions can yield many symptoms).
2093
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002094- Added a C API for set and frozenset objects.
2095

2097
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002098- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2099 mapping argument now. This string is used as a mapping table. Byte values
2100 greater than the length of the string and 0xFFFE are treated as undefined
2101 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002108
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002109- Patch #1276356: New resource "urlfetch" is implemented. This enables
2110 even impatient people to run tests that require remote files.
