Guido van Rossumc69ac252006-08-10 18:09:25 +000057What's New in Python 2.5 release candidate 1?
58=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +000059
Anthony Baxterb4096662006-08-16 03:42:26 +000060*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +000061
62Core and builtins
63-----------------
64
Marc-André Lemburg040f76b2006-08-14 10:55:19 +000065- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000066 compared equal or unequal to a string and a UnicodeDecodeError
67 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +000068
Marc-André Lemburg040f76b2006-08-14 10:55:19 +000069 Instead, the equal (==) and unequal (!=) comparison operators will
70 now issue a UnicodeWarning and interpret the two objects as
71 unequal. The UnicodeWarning can be filtered as desired using
72 the warning framework, e.g. silenced completely, turned into an
73 exception, logged, etc.
74
75 Note that compare operators other than equal and unequal will still
76 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +000077
Marc-André Lemburg757ea272006-08-14 11:44:34 +000078- Fix segfault when doing string formatting on subclasses of long.
79
80- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
81 with new-style classes.
82
83- Fix bug related to __len__ functions returning negative values with
84 classic classes.
85
86- Patch #1538606, Fix __index__() clipping. There were some problems
87 discovered with the API and how integers that didn't fit into Py_ssize_t
88 were handled. This patch attempts to provide enough alternatives
89 to effectively use __index__.
90
Martin v. Löwisab2f8f72006-08-09 07:57:39 +000091- Bug #1536021: __hash__ may now return long int; the final hash
92 value is obtained by invoking hash on the long int.
93
Thomas Hellerab1049c2006-08-08 17:37:00 +000094- Bug #1536786: buffer comparison could emit a RuntimeWarning.
95
Georg Brandl7e3ba2a2006-08-06 08:23:54 +000096- Bug #1535165: fixed a segfault in input() and raw_input() when
97 sys.stdin is closed.
98
Thomas Heller74d36f02006-08-04 18:17:40 +000099- On Windows, the PyErr_Warn function is now exported from
100 the Python dll again.
101
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000102- Bug #1191458: tracing over for loops now produces a line event
103 on each iteration. Fixing this problem required changing the .pyc
104 magic number. This means that .pyc files generated before 2.5c1
105 will be regenerated.
106
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000107- Bug #1333982: string/number constants were inappropriately stored
108 in the byte code and co_consts even if they were not used, ie
109 immediately popped off the stack.
110
Georg Brandle9462c72006-08-04 18:03:37 +0000111- Fixed a reference-counting problem in property().
112
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000113
114Library
115-------
116
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000117- Fix a bug in the ``compiler`` package that caused invalid code to be
118 generated for generator expressions.
119
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000120- The distutils version has been changed to 2.5.0. The change to
121 keep it programmatically in sync with the Python version running
122 the code (introduced in 2.5b3) has been reverted. It will continue
123 to be maintained manually as static string literal.
124
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000125- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000126 and this cannot be converted to the required C type, an exception is
127 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000128 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000129
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000130- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000131 an exception.
132
Tim Peterscbdd3502006-09-05 01:47:53 +0000133- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000134 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000135 workarounds for clocks with low resolution, to stop the code yielding
136 duplicate UUIDs.
137
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000138- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
139 before raising SystemExit, allowing IDLE to honor quit() and exit().
140
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000141- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
142
Georg Brandl7a1af772006-08-14 21:55:28 +0000143- Patch #1536071: trace.py should now find the full module name of a
144 file correctly even on Windows.
145
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000146- logging's atexit hook now runs even if the rest of the module has
147 already been cleaned up.
148
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000149- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000150
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000151- Bug #1531405, format_exception no longer raises an exception if
152 str(exception) raised an exception.
153
Neil Schemenauer06ded092006-08-04 16:20:30 +0000154- Fix a bug in the ``compiler`` package that caused invalid code to be
155 generated for nested functions.
156
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000157

162
Georg Brandl3335a7a2006-08-14 21:42:55 +0000163- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
164 raises the correct exceptions.
165
Thomas Heller1ce433e2006-08-14 16:20:04 +0000166- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
167 '-no-stack-protector' compiler flag for OpenBSD has been removed.
168
Thomas Heller86720042006-08-14 11:17:48 +0000169- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
170 uses the _as_parameter_ attribute when objects are passed to foreign
171 function calls. The ctypes version number was changed to 1.0.1.
172
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000173- Bug #1530559, struct.pack raises TypeError where it used to convert.
174 Passing float arguments to struct.pack when integers are expected
175 now triggers a DeprecationWarning.
176
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000177

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000198Build
199-----
200
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000201- Bug #1535502, build _hashlib on Windows, and use masm assembler
202 code in OpenSSL.
203
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000204- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

210-----
211
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000212- New API for Unicode rich comparisons: PyUnicode_RichCompare()
213
Tim Peters4643c2f2006-08-10 22:45:34 +0000214- Bug #1069160. Internal correctness changes were made to
215 ``PyThreadState_SetAsyncExc()``. A test case was added, and
216 the documentation was changed to state that the return value

Fred Drake53912162006-07-29 13:22:49 +0000220What's New in Python 2.5 beta 3?
221================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000222
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000223*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000224
225Core and builtins
226-----------------
227
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000228- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000229 returned a long (see PEP 353).
230
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000231- Bug #1515471: string.replace() accepts character buffers again.
232
Neal Norwitz07aadb12006-07-30 06:55:48 +0000233- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
234 This provides the proper warning for struct.pack().
235 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
236
Neal Norwitz0d62a062006-07-30 06:53:31 +0000237- Patch #1531113: Fix augmented assignment with yield expressions.
238 Also fix a SystemError when trying to assign to yield expressions.
239
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000240- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
241 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
242 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
243 excessive filesystem operations during imports.
244
Tim Petersbc24eee2006-07-27 01:14:53 +0000245- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
246 operations on signed longs that are formally undefined by C.
247 Unfortunately, at least one compiler now cares about that, so complicated
248 the code to make that compiler happy again.
249
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000250- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
251
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000252- Patch #1232023: Stop including current directory in search
253 path on Windows.
254
Neal Norwitze1fdb322006-07-21 05:32:28 +0000255- Fix some potential crashes found with failmalloc.
256
Neal Norwitze7563102006-07-17 01:00:16 +0000257- Fix warnings reported by Klocwork's static analysis tool.
258
Neal Norwitz84be93b2006-07-16 01:50:38 +0000259- Bug #1512814, Fix incorrect lineno's when code within a function
260 had more than 255 blank lines.
261
Georg Brandl9dceedb2006-07-12 15:31:17 +0000262- Patch #1521179: Python now accepts the standard options ``--help`` and
263 ``--version`` as well as ``/?`` on Windows.
264
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000265- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000266 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000267 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000268
Tim Peters112aad32006-07-19 00:03:19 +0000269- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000270 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000271 new ``sys._current_frames()`` returns a dictionary with one entry,
272 mapping the faux "thread id" 0 to the current frame.
273
Ronald Oussoren3075e162006-07-25 20:28:55 +0000274- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000275
Ronald Oussoren3075e162006-07-25 20:28:55 +0000276
Neal Norwitza1f10902006-07-12 07:28:29 +0000277Library
278-------
279
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000280- Correction of patch #1455898: In the mbcs decoder, set final=False
281 for stream decoder, but final=True for the decode function.
282
Georg Brandl07fec3a2006-08-01 18:49:24 +0000283- os.urandom no longer masks unrelated exceptions like SystemExit or
284 KeyboardInterrupt.
285
Tim Peters4643c2f2006-08-10 22:45:34 +0000286- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000287 shutil.copytree on Windows
288
Georg Brandle34ac7c2006-07-30 11:07:23 +0000289- Bug #1002398: The documentation for os.path.sameopenfile now correctly
290 refers to file descriptors, not file objects.
291
Tim Peterscbdd3502006-09-05 01:47:53 +0000292- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000293 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000294 #1513611, and probably others.
295
Georg Brandledd9b0d2006-07-29 09:33:26 +0000296- Bug #1441397: The compiler module now recognizes module and function
297 docstrings correctly as it did in Python 2.4.
298
Tim Peters6f681472006-07-27 23:44:37 +0000299- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
300 lost that tests are sorted by name before being run. This rarely
301 matters for well-written tests, but can create baffling symptoms if
302 side effects from one test to the next affect outcomes. ``DocTestFinder``
303 has been changed to sort the list of tests it returns.
304
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000305- The distutils version has been changed to 2.5.0, and is now kept

Georg Brandldb232dc2006-08-20 13:15:43 +0000310- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
311 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000312
Georg Brandlcf0c1722006-07-26 07:23:32 +0000313- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
314 to recursive calls and call it with the failing package name.
315
Martin v. Löwis0b483032006-07-25 09:53:12 +0000316- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
317
Georg Brandlc13c34c2006-07-24 14:09:56 +0000318- Patch #1515343: Fix printing of deprecated string exceptions with a
319 value in the traceback module.
320
Greg Ward48fae7a2006-07-23 16:05:51 +0000321- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
322
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000323- Patch #1524429: Use repr() instead of backticks in Tkinter again.
324
Brett Cannoncaebe222006-07-18 04:41:36 +0000325- Bug #1520914: Change time.strftime() to accept a zero for any position in its
326 argument tuple. For arguments where zero is illegal, the value is forced to
327 the minimum value that is correct. This is to support an undocumented but
328 common way people used to fill in inconsequential information in the time
329 tuple pre-2.4.
330
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000331- Patch #1220874: Update the binhex module for Mach-O.
332
Barry Warsawb110bad2006-07-21 14:51:07 +0000333- The email package has improved RFC 2231 support, specifically for
334 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
335 (name*0=<blah>) parameter continuations. This may change the types of
336 values returned from email.message.Message.get_param() and friends.
337 Specifically in some cases where non-encoded continuations were used,
338 get_param() used to return a 3-tuple of (None, None, string) whereas now it
339 will just return the string (since non-encoded continuations don't have
340 charset and language parts).
341
342 Also, whereas % values were decoded in all parameter continuations, they are
343 now only decoded in encoded parameter parts.
344
Ronald Oussoren3075e162006-07-25 20:28:55 +0000345- Bug #1517990: IDLE keybindings on MacOS X now work correctly
346
347- Bug #1517996: IDLE now longer shows the default Tk menu when a
348 path browser, class browser or debugger is the frontmost window on MacOS X
349
Barry Warsaw00decd72006-07-27 23:43:15 +0000350- Patch #1520294: Support for getset and member descriptors in types.py,
351 inspect.py, and pydoc.py. Specifically, this allows for querying the type
352 of an object against these built-in types and more importantly, for getting
353 their docstrings printed in the interactive interpreter's help() function.

360 a socket operation on a socket with a timeout, the exception will be
361 caught correctly. Previously, the exception was not caught.
362
Thomas Heller1393d6a2006-07-28 21:43:20 +0000363- Patch #1529514: The _ctypes extension is now compiled on more
364 openbsd target platforms.
365
Tim Peters9cab5932006-07-28 00:30:00 +0000366- The ``__reduce__()`` method of the new ``collections.defaultdict`` had

Thomas Hellerce049a02006-07-14 17:51:14 +0000374- Patch #1521817: Index range checking on ctypes arrays containing
375 exactly one element enabled again. This allows iterating over these
376 arrays, without the need to check the array size before.
377
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000378- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000379 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000380 /dev/null in certain cases; this is now fixed.
381
Thomas Heller47d7a062006-07-12 08:43:47 +0000382- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
383 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000384
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000385- Because of a misspelled preprocessor symbol, ctypes was always
386 compiled without thread support; this is now fixed.
387
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000388- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
389 methods now allow their database parameter to be None as the
390 sleepycat API allows.
391
Matt Flemingec926502006-07-28 11:27:27 +0000392- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
393 bluetooth API compared with Linux and FreeBSD.

396-----
397
398- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
399 how long the test file should take to play. Now accepts taking 2.93 secs
400 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
401
Georg Brandl4793aa32006-07-28 18:31:39 +0000402- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
403 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
404 run via ``regrtest.py``. Now they do.

413
414- PythonLauncher now works correctly when the path to the script contains
415 characters that are treated specially by the shell (such as quotes).
416
417- Bug #1527397: PythonLauncher now launches scripts with the working directory
418 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000419 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000420 expect.

430
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000431- Bug #1441486: The literal representation of -(sys.maxint - 1)
432 again evaluates to a int object, not a long.
433
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000434- Bug #1501934: The scope of global variables that are locally assigned
435 using augmented assignment is now correctly determined.
436
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000437- Bug #927248: Recursive method-wrapper objects can now safely
438 be released.
439
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000440- Bug #1417699: Reject locale-specific decimal point in float()
441 and atof().
442
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000443- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
444 omit a default "error" argument for NULL pointer. This allows
445 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000446
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000447- Bug #1519018: 'as' is now validated properly in import statements.
448
Neal Norwitz28746ab2006-07-09 22:14:42 +0000449- On 64 bit systems, int literals that use less than 64 bits are
450 now ints rather than longs.
451
Neal Norwitzed657552006-07-10 00:04:44 +0000452- Bug #1512814, Fix incorrect lineno's when code at module scope
453 started after line 256.
454
Tim Peters32a83612006-07-10 21:08:24 +0000455- New function ``sys._current_frames()`` returns a dict mapping thread
456 id to topmost thread stack frame. This is for expert use, and is
457 especially useful for debugging application deadlocks. The functionality
458 was previously available in Fazal Majid's ``threadframe`` extension
459 module, but it wasn't possible to do this in a wholly threadsafe way from
460 an extension.

507
Brett Cannon53ab5b72006-06-22 16:49:14 +0000508- Bug #1510580: The 'warnings' module improperly required that a Warning
509 category be either a types.ClassType and a subclass of Warning. The proper
510 check is just that it is a subclass with Warning as the documentation states.
511
Georg Brandlad29e632006-06-21 17:45:17 +0000512- The compiler module now correctly compiles the new try-except-finally
513 statement (bug #1509132).
514
Neal Norwitz60373cd2006-06-22 06:30:50 +0000515- The wsgiref package is now installed properly on Unix.

Tim Peters112aad32006-07-19 00:03:19 +0000527- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
528 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
529 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000530
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000531- Assigning None to pointer type fields in ctypes structures possible
532 overwrote the wrong fields, this is fixed now.
533
534- Fixed a segfault in _ctypes when ctypes.wintypes were imported
535 on non-Windows platforms.
536
537- Bug #1518190: The ctypes.c_void_p constructor now accepts any
538 integer or long, without range checking.
539
540- Patch #1517790: It is now possible to use custom objects in the ctypes
541 foreign function argtypes sequence as long as they provide a from_param
542 method, no longer is it required that the object is a ctypes type.
543
544- The '_ctypes' extension module now works when Python is configured

562
Tim Peters32a83612006-07-10 21:08:24 +0000563- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000564 Previously, the slight difference could cause compilation errors of the
565 'zlib' module on systems with more than one version of zlib.
566
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000567- The MSI compileall step was fixed to also support a TARGETDIR

Neal Norwitzb9845e72006-06-12 02:11:18 +0000612
Brett Cannon22565aa2006-06-09 22:31:23 +0000613- Bug #532646: object.__call__() will continue looking for the __call__
614 attribute on objects until one without one is found. This leads to recursion
615 when you take a class and set its __call__ attribute to an instance of the
616 class. Originally fixed for classic classes, but this fix is for new-style.
617 Removes the infinite_rec_3 crasher.
618
Georg Brandl24250812006-06-09 18:45:48 +0000619- The string and unicode methods startswith() and endswith() now accept
620 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
621
Brett Cannonde3b0522006-06-08 17:00:45 +0000622- Buffer objects, at the C level, never used the char buffer
623 implementation even when the char buffer for the wrapped object was
624 explicitly requested (originally returned the read or write buffer).
625 Now a TypeError is raised if the char buffer is not present but is
626 requested.
627
Georg Brandlddbaa662006-06-04 21:56:52 +0000628- Patch #1346214: Statements like "if 0: suite" are now again optimized
629 away like they were in Python 2.4.
630
Georg Brandlb7c8f542006-05-27 12:30:25 +0000631- Builtin exceptions are now full-blown new-style classes instead of
632 instances pretending to be classes, which speeds up exception handling
633 by about 80% in comparison to 2.5a2.
634
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000635- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
636 Unicode 4.1.
637
Georg Brandlf4ef1162006-05-26 18:03:31 +0000638- Patch #921466: sys.path_importer_cache is now used to cache valid and
639 invalid file paths for the built-in import machinery which leads to
640 fewer open calls on startup.
641
Tim Peters696cf432006-05-24 21:10:40 +0000642- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
643 of-2 bases. The largest speedup is for inputs with about 1000 decimal
644 digits. Conversion from non-power-of-2 bases remains quadratic-time in
645 the number of input digits (it was and remains linear-time for bases
646 2, 4, 8, 16 and 32).
647
Tim Petersb713ec22006-05-23 18:45:30 +0000648- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
649 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
650 an integer close to ``sys.maxint``. This was repaired by patch
651 #1335972, which also gives a nice speedup.
652
Richard Jonescebbefc2006-05-23 18:28:17 +0000653- Patch #1337051: reduced size of frame objects.
654
655- PyErr_NewException now accepts a tuple of base classes as its
656 "base" parameter.
657
Richard Jones7c88dcc2006-05-23 10:37:38 +0000658- Patch #876206: function call speedup by retaining allocated frame
659 objects.
660
Georg Brandl7b90e162006-05-18 07:01:27 +0000661- Bug #1462152: file() now checks more thoroughly for invalid mode
662 strings and removes a possible "U" before passing the mode to the
663 C library function.
664
Neal Norwitz1004a532006-05-15 07:17:23 +0000665- Patch #1488312, Fix memory alignment problem on SPARC in unicode
666
Neal Norwitz373f0a72006-05-15 07:04:36 +0000667- Bug #1487966: Fix SystemError with conditional expression in assignment
668
Martin v. Löwis879768d2006-05-11 13:28:43 +0000669- WindowsError now has two error code attributes: errno, which carries
670 the error values from errno.h, and winerror, which carries the error
671 values from winerror.h. Previous versions put the winerror.h values
672 (from GetLastError()) into the errno attribute.
673
Martin v. Löwis77736712006-05-04 05:51:03 +0000674- Patch #1475845: Raise IndentationError for unexpected indent.
675
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000676- Patch #1479181: split open() and file() from being aliases for each other.
677
Tim Peters44bd9862006-06-01 13:49:23 +0000678- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
679 methods were always silently ignored by dictionaries when comparing keys.
680 They are now passed through (except when using the C API function
681 ``PyDict_GetItem()``, whose semantics did not change).
682
683- Bug #1456209: In some obscure cases it was possible for a class with a
684 custom ``__eq__()`` method to confuse dict internals when class instances
685 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
686 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000688Extension Modules
689-----------------
690
Trent Mick960a3f82006-06-28 20:30:41 +0000691- Bug #1295808: expat symbols should be namespaced in pyexpat
692
693- Patch #1462338: Upgrade pyexpat to expat 2.0.0
694
Brett Cannon6ee7d012006-06-08 16:23:04 +0000695- Change binascii.hexlify to accept a read-only buffer instead of only a char
696 buffer and actually follow its documentation.
697
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000698- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
699
Nick Coghlanc649ec52006-05-29 12:43:05 +0000700- Patch #1478788 (modified version): The functional extension module has
701 been renamed to _functools and a functools Python wrapper module added.
702 This provides a home for additional function related utilities that are
703 not specifically about functional programming. See PEP 309.
704
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000705- Patch #1493701: performance enhancements for struct module.
706
Georg Brandl378d5922006-05-17 14:26:50 +0000707- Patch #1490224: time.altzone is now set correctly on Cygwin.
708
Georg Brandl8d3342b2006-05-16 07:38:27 +0000709- Patch #1435422: zlib's compress and decompress objects now have a
710 copy() method.
711
Andrew MacIntyre92913322006-06-13 15:04:24 +0000712- Patch #1454481: thread stack size is now tunable at runtime for thread
713 enabled builds on Windows and systems with Posix threads support.
714
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000715- On Win32, os.listdir now supports arbitrarily-long Unicode path names
716 (up to the system limit of 32K characters).
717
718- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
719 As a result, these functions now raise WindowsError instead of OSError.
720
Tim Peters7a822da2006-05-25 21:50:17 +0000721- ``time.clock()`` on Win64 should use the high-performance Windows
722 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
723 Windows platforms).
724
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000725- Calling Tk_Init twice is refused if the first call failed as that
726 may deadlock.
727
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000728- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
729 accept it without potentially using an uninitialized pointer.
730
731- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
732 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
733 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000734
Gregory P. Smith372b5832006-06-05 18:48:21 +0000735- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000736 [pybsddb project SF patch number 1466734]
737
Gregory P. Smith372b5832006-06-05 18:48:21 +0000738- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
739 parameter is supplied. [SF pybsddb bug #1477863]
740
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000741- bsddb: the __len__ method of a DB object has been fixed to return correct
742 results. It could previously incorrectly return 0 in some cases.
743 Fixes SF bug 1493322 (pybsddb bug 1184012).
744
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000745- bsddb: the bsddb.dbtables Modify method now raises the proper error and
746 aborts the db transaction safely when a modifier callback fails.
747 Fixes SF python patch/bug #1408584.
748
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000749- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000750 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000751 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
752 database calls that would previously deadlock. [SF python bug #775414]
753
Vinay Sajip28e57612006-07-01 10:45:20 +0000754- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000755
Walter Dörwald4994d952006-06-19 08:07:50 +0000756- Patch #1506645: add Python wrappers for the curses functions
757 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000758

761
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000762- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
763 functions.
764
Martin v. Löwis3798da02006-06-17 18:44:27 +0000765- Patch #812986: Update turtle output even if not tracing.
766
Vinay Sajip28e57612006-07-01 10:45:20 +0000767- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000768 Tkinter.BaseWidget.
769
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000770- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
771
Martin v. Löwis337487e2006-06-17 09:15:14 +0000772- Patch #763580: Add name and value arguments to Tkinter variable
773 classes.
774
Georg Brandl83cc0d02006-06-14 08:50:03 +0000775- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
776 mime.types file for determining MIME types.
777
Georg Brandl2605ca82006-06-14 06:08:31 +0000778- Bug #1339007: Shelf objects now don't raise an exception in their
779 __del__ method when initialization failed.
780
Martin v. Löwisd8251432006-06-14 05:21:04 +0000781- Patch #1455898: The MBCS codec now supports the incremental mode for
782 double-byte encodings.
783
Tim Peters43898b42006-06-14 04:09:25 +0000784- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
785 guarantee that adjacent triples in the return list always describe
786 non-adjacent blocks. Previously, a pair of matching blocks could end
787 up being described by multiple adjacent triples that formed a partition
788 of the matching pair.
789
Greg Ward0e0c9f42006-06-11 16:24:11 +0000790- Bug #1498146: fix optparse to handle Unicode strings in option help,
791 description, and epilog.
792
Greg Wardd1c797e2006-06-11 14:42:41 +0000793- Bug #1366250: minor optparse documentation error.
794
Greg Ward7f547402006-06-11 00:40:49 +0000795- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
796 clarify docs.
797
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000798- The wsgiref package has been added to the standard library.
799
Nick Coghlan676725d2006-06-08 13:54:49 +0000800- The functions update_wrapper() and wraps() have been added to the functools
801 module. These make it easier to copy relevant metadata from the original
802 function when writing wrapper functions.
803
Tim Petersd6a9eef2006-06-05 01:48:21 +0000804- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
805 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000806
Martin v. Löwis3f767792006-06-04 19:36:28 +0000807- Patch #1359618: Speed up charmap encoder by using a trie structure
808 for lookup.
809
Tim Petersd609b1a2006-06-02 23:22:51 +0000810- The functions in the ``pprint`` module now sort dictionaries by key
811 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
812 if and only if its display required more than one line, although that
813 wasn't documented. The new behavior increases predictability; e.g.,
814 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
815
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000816- Patch #1497027: try HTTP digest auth before basic auth in urllib2
817 (thanks for J. J. Lee).
818
Georg Brandl2b330372006-05-28 20:23:12 +0000819- Patch #1496206: improve urllib2 handling of passwords with respect to
820 default HTTP and HTTPS ports.
821
George Yoshidaf3c65de2006-05-28 16:39:09 +0000822- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
823
Bob Ippolito7298f272006-05-23 18:43:47 +0000824- Patch #1281707: speed up gzip.readline.
825
Georg Brandlb89316f2006-05-17 15:51:16 +0000826- Patch #1180296: Two new functions were added to the locale module:
827 format_string() to get the effect of "format % items" but locale-aware,
828 and currency() to format a monetary number with currency sign.
829
Georg Brandle3a25832006-05-17 14:56:04 +0000830- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
831 and several features added, such as speed and geometry control.
832
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000833- Patch #1488881: add support for external file objects in bz2 compressed
834 tarfiles.
835
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000836- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
837 stdout arguments, making it possible to redirect input and output
838 for remote debugging.
839
840- Patch #1484695: Update the tarfile module to version 0.8. This fixes
841 a couple of issues, notably handling of long file names using the
842 GNU LONGNAME extension.
843
844- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
845 new flag when ``name`` is already the name of an option flag.
846
847- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
848 package.
849
850- Patch #1472854: make the rlcompleter.Completer class usable on non-
851 UNIX platforms.
852
853- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
854
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000855- Bug #1472827: correctly escape newlines and tabs in attribute values in
856 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000886What's New in Python 2.5 alpha 2?
887=================================
888
889*Release date: 27-APR-2006*
890
891Core and builtins
892-----------------
893
Thomas Heller1b046642006-04-18 18:51:06 +0000894- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
895 by converting these apis from macros into exported functions again:
896
897 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
898 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
899 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
900 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
901 PyRun_String Py_CompileString
902
Martin v. Löwis45294a92006-04-18 06:24:08 +0000903- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
904
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000905- All uses of PyStructSequence_InitType have been changed to initialize
906 the type objects only once, even if the interpreter is initialized
907 multiple times.
908
Neal Norwitz61546162006-04-14 05:20:28 +0000909- Bug #1454485, array.array('u') could crash the interpreter. This was
910 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
911 to unicode when it didn't make sense. 'u#' now requires a unicode string.
912
913- Py_UNICODE is unsigned. It was always documented as unsigned, but
914 due to a bug had a signed value in previous versions.
915
Tim Peters3a5e8b12006-04-11 01:44:07 +0000916- Patch #837242: ``id()`` of any Python object always gives a positive
917 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
918 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000919 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000920 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000921
Tim Peters3a5e8b12006-04-11 01:44:07 +0000922 def __hash__(self):
923 return id(self) # WRONG
924
925 because a hash result must be a (short) Python int but it was always
926 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000927 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000928 was always usable as a hash value before this patch. That's no longer
929 necessarily so.
930
931- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000932 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000933 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000934 #1454844)
935
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000936- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
937 involving generators that have paused outside of any ``try`` or ``with``
938 blocks. (In 2.5a1, a paused generator that was part of a reference
939 cycle could not be garbage collected, regardless of whether it was
940 paused in a ``try`` or ``with`` block.)

953- Bug #1117761: bsddb.*open() no longer raises an exception when using
954 the cachesize parameter.
955

957 a temporary db (file=None) with the 'n' flag to truncate on open.
958
959- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
960 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000961

966-------
967
Peter Astrand7d1d4362006-07-14 14:04:45 +0000968- Bug #1223937: subprocess.CalledProcessError reports the exit status
969 of the process using the returncode attribute, instead of
970 abusing errno.
971
Tim Peters711bf302006-04-25 03:31:36 +0000972- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
973 a doctest to be skipped (the code is not run, and the expected output
974 or exception is ignored).
975
Nick Coghlanda2268f2006-04-24 04:37:15 +0000976- Fixed contextlib.nested to cope with exceptions being raised and
977 caught inside exit handlers.
978
Greg Wardab05edc2006-04-23 03:47:58 +0000979- Updated optparse module to Optik 1.5.1 (allow numeric constants in
980 hex, octal, or binary; add ``append_const`` action; keep going if
981 gettext cannot be imported; added ``OptionParser.destroy()`` method;
982 added ``epilog`` for better help generation).
983
Tim Peters21fbd572006-04-21 21:18:10 +0000984- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
985 called from a thread spawned as a side effect of importing a module.
986
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000987- The pydoc module now supports documenting packages contained in
988 .zip or .egg files.
989
990- The pkgutil module now has several new utility functions, such
991 as ``walk_packages()`` to support working with packages that are either
992 in the filesystem or zip files.
993
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000994- The mailbox module can now modify and delete messages from
995 mailboxes, in addition to simply reading them. Thanks to Gregory
996 K. Johnson for writing the code, and to the 2005 Google Summer of
997 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000998
Tim Petersc7605f22006-04-17 21:12:33 +0000999- The ``__del__`` method of class ``local`` in module ``_threading_local``

1009 Windows. Bug #1469163.
1010
Phillip J. Eby47032112006-04-11 01:07:43 +00001011- The warnings, linecache, inspect, traceback, site, and doctest modules

1021
Skip Montanaro262fb922006-04-21 02:31:07 +00001022- The pstats.Stats class accepts an optional stream keyword argument to
1023 direct output to an alternate file-like object.
1024
Anthony Baxter51bcb682006-04-05 14:51:42 +00001025Build
1026-----
1027
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001028- The Makefile now has a reindent target, which runs reindent.py on
1029 the library.
1030
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001031- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001034
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001035- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1036 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001037 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001038 CXX from --with-cxx-main, see description in README.
1039
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001040- Patch #1429775: Link extension modules with the shared libpython.
1041
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001042- Fixed a libffi build problem on MIPS systems.
1043
Tim Peters8931ff12006-05-13 23:28:20 +00001044- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1045 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1046 and "%zu" for unsigned integers of type ``size_t``.
1047
Anthony Baxter51bcb682006-04-05 14:51:42 +00001048Tests
1049-----
1050
Nick Coghlanda2268f2006-04-24 04:37:15 +00001051- test_contextlib now checks contextlib.nested can cope with exceptions
1052 being raised and caught inside exit handlers.
1053
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001054- test_cmd_line now checks operation of the -m and -c command switches
1055
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001056- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1057 it separately and by hand. It also wasn't cleaning up its changes to
1058 the current Decimal context.
1059
Thomas Woutersabd08882006-04-26 15:53:30 +00001060- regrtest.py now has a -M option to run tests that test the new limits of
1061 containers, on 64-bit architectures. Running these tests is only sensible
1062 on 64-bit machines with more than two gigabytes of memory. The argument
1063 passed is the maximum amount of memory for the tests to use.

1072-------------
1073
Tim Petersb06d28c2006-05-12 01:57:59 +00001074- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1075
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001076- PEP 343: Added Context Types section to the library reference
1077 and attempted to bring other PEP 343 related documentation into
1078 line with the implementation and/or python-dev discussions.
1079
Tim Peters8dc73d22006-04-24 02:03:16 +00001080- Bug #1337990: clarified that ``doctest`` does not support examples
1081 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001084What's New in Python 2.5 alpha 1?
1085=================================

Anthony Baxterebed3f62006-04-03 15:03:44 +00001087*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001088
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001089Core and builtins
1090-----------------
1091
Nick Coghlan43832302006-04-23 17:04:07 +00001092- PEP 338: -m command line switch now delegates to runpy.run_module
1093 allowing it to support modules in packages and zipfiles
1094
Martin v. Löwisc661b882006-04-20 04:54:23 +00001095- On Windows, .DLL is not an accepted file name extension for
1096 extension modules anymore; extensions are only found if they
1097 end in .PYD.
1098
Martin v. Löwisea62d252006-04-03 10:56:49 +00001099- Bug #1421664: sys.stderr.encoding is now set to the same value as
1100 sys.stdout.encoding.
1101
Neal Norwitz92e212f2006-04-03 04:48:37 +00001102- __import__ accepts keyword arguments.
1103
Georg Brandlccadf842006-03-31 18:54:53 +00001104- Patch #1460496: round() now accepts keyword arguments.
1105
Anthony Baxter262c00a2006-03-30 10:53:17 +00001106- Fixed bug #1459029 - unicode reprs were double-escaped.
1107
Hye-Shik Changd478f342006-03-23 12:32:36 +00001108- Patch #1396919: The system scope threads are reenabled on FreeBSD
1109 5.4 and later versions.
1110
Neal Norwitze98ccf62006-03-23 05:39:47 +00001111- Bug #1115379: Compiling a Unicode string with an encoding declaration
1112 now gives a SyntaxError.
1113
Georg Brandlabd1ff82006-03-18 07:59:59 +00001114- Previously, Python code had no easy way to access the contents of a
1115 cell object. Now, a ``cell_contents`` attribute has been added
1116 (closes patch #1170323).
1117
Tim Peterscf79aac2006-03-16 01:14:46 +00001118- Patch #1123430: Python's small-object allocator now returns an arena to
1119 the system ``free()`` when all memory within an arena becomes unused
1120 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1121 freed. Some applications will see a drop in virtual memory size now,
1122 especially long-running applications that, from time to time, temporarily
1123 use a large number of small objects. Note that when Python returns an
1124 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001125 platform C library will in turn return that memory to the operating system.
1126 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001127 appears to be effective at least on Microsoft C and gcc-based systems.
1128 Thanks to Evan Jones for hard work and patience.
1129
Georg Brandl533ff6f2006-03-08 18:09:27 +00001130- Patch #1434038: property() now uses the getter's docstring if there is
1131 no "doc" argument given. This makes it possible to legitimately use
1132 property() as a decorator to produce a read-only property.
1133
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001134- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1135 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1136 of requiring an int or long in slicing and a few other contexts, enabling
1137 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1138
Neal Norwitz995acdf2006-03-07 05:01:00 +00001139- Fixed various bugs reported by Coverity's Prevent tool.
1140
Brett Cannonbf364092006-03-01 04:25:17 +00001141- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1142 new exception base class, BaseException, which has a new message attribute.
1143 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1144 Raising a string exception now raises a DeprecationWarning.
1145
Thomas Woutersfb609f42006-02-28 16:37:25 +00001146- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1147 explicitly relative, using 'from .module import name' to mean 'from the same
1148 package as this module is in. Imports without dots still default to the
1149 old relative-then-absolute, unless 'from __future__ import
1150 absolute_import' is used.
1151
Brett Cannona7446e32006-02-27 23:39:10 +00001152- Properly check if 'warnings' raises an exception (usually when a filter set
1153 to "error" is triggered) when raising a warning for raising string
1154 exceptions.
1155
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001156- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001157 The name was removed from Include/code.h.
1158
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001159- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001160
Guido van Rossum1968ad32006-02-25 22:38:04 +00001161- Patch 1433928:
1162 - The copy module now "copies" function objects (as atomic objects).
1163 - dict.__getitem__ now looks for a __missing__ hook before raising
1164 KeyError.
1165
Tim Peters84ef21c2006-02-28 20:39:06 +00001166- PEP 343: with statement implemented. Needs ``from __future__ import
1167 with_statement``. Use of 'with' as a variable will generate a warning.
1168 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001169 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001170 The following objects have __context__ methods:
1171 - The built-in file type.
1172 - The thread.LockType type.
1173 - The following types defined by the threading module:
1174 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1175 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001176
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001177- Fix the encodings package codec search function to only search
1178 inside its own package. Fixes problem reported in patch #1433198.
1179
1180 Note: Codec packages should implement and register their own
1181 codec search function. PEP 100 has the details.
1182
Tim Peters9ea89d22006-06-04 03:26:02 +00001183- PEP 353: Using ``Py_ssize_t`` as the index type.
1184
1185- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1186 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1187 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1188 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1189 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001190
Neal Norwitzfc76d632006-01-10 06:03:13 +00001191- Patch #1400181, fix unicode string formatting to not use the locale.
1192 This is how string objects work. u'%f' could use , instead of .
1193 for the decimal point. Now both strings and unicode always use periods.
1194
Neal Norwitz671b9e32006-01-09 07:07:12 +00001195- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1196 configure would break checking curses.h.
1197
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001198- Bug #959576: The pwd module is now builtin. This allows Python to be
1199 built on UNIX platforms without $HOME set.
1200
Neal Norwitzc10978f2005-12-19 06:07:16 +00001201- Bug #1072182, fix some potential problems if characters are signed.
1202
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001203- Bug #889500, fix line number on SyntaxWarning for global declarations.
1204
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001205- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1206
Neal Norwitze7214a12005-12-18 05:03:17 +00001207- Support for converting hex strings to floats no longer works.
1208 This was not portable. float('0x3') now raises a ValueError.
1209
Barry Warsaw2a38a862005-12-18 01:27:35 +00001210- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001211 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001212 is now displayed in interactive prompt banner.
1213
Georg Brandlfa166682005-12-17 21:45:17 +00001214- Implementation of PEP 341 - Unification of try/except and try/finally.
1215 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001216 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001217
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001218- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1219 now encodes backslash correctly.
1220
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001221- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1222
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001223- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001224 and long longs.
1225
Neal Norwitz67715f02005-11-09 06:59:35 +00001226- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001227 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001228 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001229
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001230- Replaced most Unicode charmap codecs with new ones using the
1231 new Unicode translate string feature in the builtin charmap
1232 codec; the codecs were created from the mapping tables available
1233 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1234 encodings now include a mapping for the Apple logo)
1235
Tim Peterse3547fd2005-12-16 23:13:57 +00001236- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001237
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001238- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001239
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001240- A new AST parser implementation was completed. The abstract
1241 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001242 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001243
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001244- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001245 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1246
Neal Norwitz708e51a2005-10-03 04:48:15 +00001247- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1248
Neal Norwitz11bd1192005-10-03 00:54:56 +00001249- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1250 Provide a warning when a directory is passed on the command line.
1251
Neal Norwitz40d37812005-10-02 01:48:49 +00001252- Fix segfault with invalid coding.
1253
1254- SF bug #772896: unknown encoding results in MemoryError.
1255
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001256- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001257 supported a __len__() method which evaluated to False when the iterator
1258 was empty.
1259
Guido van Rossum630db602005-09-20 18:49:54 +00001260- On 64-bit platforms, when __len__() returns a value that cannot be
1261 represented as a C int, raise OverflowError.
1262
Skip Montanarof8948ca2005-09-19 03:54:46 +00001263- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001264 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001265
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001266- SF bug #893549: parsing keyword arguments was broken with a few format
1267 codes.
1268
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001269- Changes donated by Elemental Security to make it work on AIX 5.3
1270 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1271 bug #105470: test_pwd fails on 64bit system (Opteron).
1272
Guido van Rossum539c6622005-09-14 17:49:54 +00001273- Changes donated by Elemental Security to make it work on HP-UX 11 on
1274 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1275
Georg Brandl4550b8d2005-08-26 06:43:52 +00001276- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001277 (fixes bug #1119418).
1278
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001279- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1280
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001281- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1282 exceptions that cause a function to exit.
1283
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001284- The implementation of set() and frozenset() was revised to use its
1285 own internal data structure. Memory consumption is reduced by 1/3
1286 and there are modest speed-ups as well. The API is unchanged.
1287
Tim Petersde7990b2005-07-17 23:45:23 +00001288- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1289
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001290- SF bug #1229429: PyObject_CallMethod failed to decrement some
1291 reference counts in some error exit cases.
1292
Tim Petersecc6e6a2005-07-10 22:30:55 +00001293- SF bug #1185883: Python's small-object memory allocator took over
1294 a block managed by the platform C library whenever a realloc specified
1295 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001296 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001297 portable way to copy data from the C-managed block into Python's
1298 small-object space without risking a memory fault. Python's small-object
1299 realloc now leaves such blocks under the control of the platform C
1300 realloc.
1301
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001302- SF bug #1232517: An overflow error was not detected properly when
1303 attempting to convert a large float to an int in os.utime().
1304
Raymond Hettinger3296e692005-06-29 23:29:56 +00001305- SF bug #1224347: hex longs now print with lowercase letters just
1306 like their int counterparts.
1307
Michael W. Hudson188d4362005-06-20 16:52:57 +00001308- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1309 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1310 interpreter states; back out that fix and do a better job (see
1311 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1312 for a longer write-up of the problem).
1313
Michael W. Hudsondf888462005-06-03 14:41:55 +00001314- SF patch #1180995: marshal now uses a binary format by default when
1315 serializing floats.
1316
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001317- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1318 the routines that promise to produce IEEE 754 binary representations
1319 of floats now simply copy bytes around.
1320
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001321- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1322 278.
1323
Brett Cannonc3647ac2005-04-26 03:45:26 +00001324- patch #1109424: int, long, float, complex, and unicode now check for the
1325 proper magic slot for type conversions when subclassed. Previously the
1326 magic slot was ignored during conversion. Semantics now match the way
1327 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001328 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001329 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001330 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001331
Barry Warsawc8d907c2005-04-19 23:43:40 +00001332- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1333 NULL, now raise an AttributeError when attempting to set or delete the
1334 attribute. Previously a TypeError was raised, but this was inconsistent
1335 with the equivalent pure-Python implementation.
1336
Michael W. Hudson774479c2005-04-18 08:46:17 +00001337- It is now safe to call PyGILState_Release() before
1338 PyEval_InitThreads() (note that if there is reason to believe there
1339 are multiple threads around you still must call PyEval_InitThreads()
1340 before using the Python API; this fix is for extension modules that
1341 have no way of knowing if Python is multi-threaded yet).
1342
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001343- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1344 disabled caused a crash.
1345
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001346- Bug #1165306: instancemethod_new allowed the creation of a method
1347 with im_class == im_self == NULL, which caused a crash when called.
1348
Tim Petersecc6e6a2005-07-10 22:30:55 +00001349- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001350 fixes the crash seen in bug #1165761
1351
Raymond Hettinger96229b12005-03-11 06:49:40 +00001352- Added two new builtins, any() and all().
1353
Brett Cannon409d8f22005-03-05 06:47:57 +00001354- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001355 (e.g., ``class C(): pass`` is no longer a syntax error).
1356 Patch #1176012 added support to the 'parser' module and 'compiler' package
1357 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001358
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001359- Patch #1115086: Support PY_LONGLONG in structmember.
1360
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001361- Bug #1155938: new style classes did not check that __init__() was
1362 returning None.
1363
Tim Petersecc6e6a2005-07-10 22:30:55 +00001364- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001365 ('\') with a specific error message.
1366
Martin v. Löwisff232d72005-03-03 09:24:38 +00001367- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1368
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001369- Bug #1124295: the __name__ attribute of file objects was
1370 inadvertently made inaccessible in restricted mode.
1371
Tim Petersecc6e6a2005-07-10 22:30:55 +00001372- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001373 an ferror() call.
1374
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001375- min() and max() now support key= arguments with the same meaning as in
1376 list.sort().
1377
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001378- The peephole optimizer now performs simple constant folding in expressions:
1379 (2+3) --> (5).
1380
Raymond Hettingera422c342005-01-11 03:03:27 +00001381- set and frozenset objects can now be marshalled. SF #1098985.
1382
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001383- Bug #1077106: Poor argument checking could cause memory corruption
1384 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001385
Jeremy Hyltonab630502005-02-04 18:44:06 +00001386- The parser did not complain about future statements in illegal
1387 positions. It once again reports a syntax error if a future
1388 statement occurs after anything other than a doc string.
1389
Neil Schemenauercf52c072005-08-12 17:34:58 +00001390- Change the %s format specifier for str objects so that it returns a
1391 unicode instance if the argument is not an instance of basestring and
1392 calling __str__ on the argument returns a unicode instance.
1393
Tim Petersf4e69282006-02-27 17:15:31 +00001394- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1395 current thread state when the auto-GIL-state machinery knows about
1396 it (since the thread state is being deleted, continuing to remember it
1397 can't help, but can hurt if another thread happens to get created with
1398 the same thread id).
1399
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001400Extension Modules
1401-----------------
1402
Georg Brandl43f08a82006-03-31 18:01:16 +00001403- Patch #1380952: fix SSL objects timing out on consecutive read()s

1406
Anthony Baxterfa869072006-03-20 05:21:58 +00001407- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1408 In addition, the existing ulaw code was updated.
1409
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001410- RFE #567972: Socket objects' family, type and proto properties are

Georg Brandlbc45a3f2006-03-17 19:17:34 +00001412
Neal Norwitz10be10c2006-03-16 06:50:13 +00001413- Everything under lib-old was removed. This includes the following modules:
1414 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001415 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001416 util, whatsound, whrandom, zmod
1417
1418- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1419
1420- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001421 is deprecated. The undocumented re.engine variable no longer exists.
1422
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001423- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1424 SS2 (single-shift 2) escape sequences correctly.
1425
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001426- The unicodedata module was updated to the 4.1 version of the Unicode
1427 database. The 3.2 version is still available as unicodedata.db_3_2_0
1428 for applications that require this specific version (such as IDNA).
1429
Neal Norwitzb62c4332006-03-04 18:35:47 +00001430- The timing module is no longer built by default. It was deprecated
1431 in PEP 4 in Python 2.0 or earlier.
1432
Guido van Rossum1968ad32006-02-25 22:38:04 +00001433- Patch 1433928: Added a new type, defaultdict, to the collections module.
1434 This uses the new __missing__ hook behavior added to dict (see above).
1435
Georg Brandldbd83392006-02-20 09:42:33 +00001436- Bug #854823: socketmodule now builds on Sun platforms even when
1437 INET_ADDRSTRLEN is not defined.
1438
Georg Brandlf4f44152006-02-18 22:29:33 +00001439- Patch #1393157: os.startfile() now has an optional argument to specify
1440 a "command verb" to invoke on the file.
1441
Neal Norwitz082b2df2006-02-07 07:04:46 +00001442- Bug #876637, prevent stack corruption when socket descriptor
1443 is larger than FD_SETSIZE.
1444
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001445- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1446 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1447 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1448
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001449- Patch #1422385: The nis module now supports access to domains other
1450 than the system default domain.
1451
Martin v. Löwis14694662006-02-03 12:54:16 +00001452- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1453 are reported, the limit on path name lengths is removed, and stat reports
1454 WindowsError now (instead of OSError).
1455
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001456- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
1457
Neal Norwitz62a21122006-01-25 05:21:55 +00001458- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
1459 before the env.
1460
Martin v. Löwis11017b12006-01-14 18:12:57 +00001461- Patch #1103116: Basic AF_NETLINK support.
1462
Neal Norwitz3b4fff82006-01-11 08:54:45 +00001463- Bug #1402308, (possible) segfault when using mmap.mmap(-1, ...)
1464
Neal Norwitz88bbd732006-01-10 07:05:44 +00001465- Bug #1400822, _curses over{lay,write} doesn't work when passing 6 ints.
1466 Also fix ungetmouse() which did not accept arguments properly.
1467 The code now conforms to the documented signature.
1468
Neal Norwitz5e3d8622006-01-09 06:24:35 +00001469- Bug #1400115, Fix segfault when calling curses.panel.userptr()
1470 without prior setting of the userptr.
1471
Neal Norwitz40c6b472006-01-05 05:43:35 +00001472- Fix 64-bit problems in bsddb.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001590- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1591 been renamed to have only a single underscore prefix. This was done to
1592 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001593
Nick Coghlan43832302006-04-23 17:04:07 +00001594- PEP 338: new module runpy defines a run_module function to support
1595 executing modules which provide access to source code or a code object
1596 via the PEP 302 import mechanisms.
1597
Anthony Baxter93f5b932006-04-03 08:05:07 +00001598- The email module's parsedate_tz function now sets the daylight savings
1599 flag to -1 (unknown) since it can't tell from the date whether it should

1606 in attribute values.
1607
Anthony Baxterc51ee692006-04-01 00:57:31 +00001608- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001609 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001610 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001611 module will not be built.
1612
Tim Petersc17976e2006-04-01 00:26:53 +00001613- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1614 aren't officially supported here, and trying to use them will probably
1615 raise an exception some day. But dicts have been allowed, and "mostly
1616 worked", so support for them won't go away without warning.
1617
Georg Brandl338ef7d2006-03-31 18:42:16 +00001618- Bug #1445068: getpass.getpass() can now be given an explicit stream
1619 argument to specify where to write the prompt.
1620
Georg Brandl22ec80b2006-03-31 18:25:44 +00001621- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1628
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001629- Queue.Queue objects now support .task_done() and .join() methods
1630 to make it easier to monitor when daemon threads have completed
1631 processing all enqueued tasks. Patch #1455676.
1632

1636
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001637- email 4.0 package now integrated. This is largely the same as the email 3.0
1638 package that was included in Python 2.3, except that PEP 8 module names are
1639 now used (e.g. mail.message instead of email.Message). The MIME classes
1640 have been moved to a subpackage (e.g. email.mime.text instead of
1641 email.MIMEText). The old names are still supported for now. Several
1642 deprecated Message methods have been removed and lots of bugs have been
1643 fixed. More details can be found in the email package documentation.
1644
Walter Dörwald40108c92006-03-27 08:15:44 +00001645- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1646 (a subclass of tuple) that provides incremental decoders and encoders
1647 (a way to use stateful codecs without the stream API). Python functions
1648 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1649 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1650 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001651
Walter Dörwald067db482006-03-15 22:17:27 +00001652- Patch #1359365: Calling next() on a closed StringIO.String object raises
1653 a ValueError instead of a StopIteration now (like file and cString.String do).
1654 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1655 called before (like file and StringIO.StringIO do).

1667
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001668- PEP 343: new module contextlib.py defines decorator @contextmanager
1669 and helpful context managers nested() and closing().
1670

Martin v. Löwis3e865952006-01-24 15:51:21 +00001705 specifications, raises IOErrors when proxies for unsupported protocols
1706 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00001729 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1730 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1731 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1732 Ronald L. Rivest offered this advice for Python:
1733
1734 "The consensus of researchers in this area (at least as
1735 expressed at the NIST Hash Function Workshop 10/31/05),
1736 is that SHA-256 is a good choice for the time being, but
1737 that research should continue, and other alternatives may

1793 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001794 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001795

1818
Georg Brandl9e43acf2005-07-04 17:16:07 +00001819- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1820 as this can cause problems with apps closing all file descriptors.

1833 Bug #1224621.
1834
Raymond Hettinger68c04532005-06-10 11:05:19 +00001835- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001836 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001837 the generate_tokens() function now accepts a callable argument that
1838 terminates by raising StopIteration.
1839
Georg Brandl9166e1a2005-06-04 09:20:03 +00001840- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1848 class at all.
1849
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001850- distutils.commands.upload was added to support uploading distribution

1852
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001853- distutils.commands.register now encodes the data as UTF-8 before posting
1854 them to PyPI.
1855
Raymond Hettinger267b8682005-03-27 10:47:39 +00001856- decimal operator and comparison methods now return NotImplemented
1857 instead of raising a TypeError when interacting with other types. This
1858 allows other classes to implement __radd__ style methods and have them
1859 work as expected.
1860
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001861- Bug #1163325: Decimal infinities failed to hash. Attempting to
1862 hash a NaN raised an InvalidOperation instead of a TypeError.
1863
Tim Petersecc6e6a2005-07-10 22:30:55 +00001864- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1898
Guido van Rossumd0641422005-02-03 15:01:24 +00001899- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1900 disables recursive traversal through instance attributes, which can
1901 be exploited in various ways.
1902
Tim Peterse3547fd2005-12-16 23:13:57 +00001903- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001904 flags on the HTTP listening socket.
1905
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001906- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1907 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1908
Fred Drakefbdeaad2006-07-29 16:56:15 +00001909- Patches #893642, #1039083: add allow_none, encoding arguments to
1910 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001911
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001912- Bug #1110478: Revert os.environ.update to do putenv again.
1913
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001914- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1915
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001916- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1917
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001918- Enhancements to the csv module:
1919
1920 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001921 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001922 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001923 + Dialect parameter parsing has been re-implemented to improve error
1924 reporting.
1925 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1926 dictates.
1927 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001928 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001929 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001930 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1931 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001932 + reader now allows \r characters to be quoted (previously it only allowed
1933 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001934 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001935 + Dialect classes passed to the module are no longer instantiated by
1936 the module before being parsed (the former validation scheme required
1937 this, but the mechanism was unreliable).
1938 + The dialect registry now contains instances of the internal
1939 C-coded dialect type, rather than references to python objects.
1940 + the internal c-coded dialect type is now immutable.
1941 + register_dialect now accepts the same keyword dialect specifications
1942 as the reader and writer, allowing the user to register dialects
1943 without first creating a dialect class.
1944 + a configurable limit to the size of parsed fields has been added -
1945 previously, an unmatched quote character could result in the entire
1946 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001947 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001948 the parser field size limit (returning the former limit). The initial
1949 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001950 + A line_num attribute has been added to the reader object, which tracks
1951 the number of lines read from the source iterator. This is not
1952 the same as the number of records returned, as records can span
1953 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001954 + reader and writer objects were not being registered with the cyclic-GC.
1955 This has been fixed.
1956
Brett Cannone6539c42005-01-08 02:43:53 +00001957- _DummyThread objects in the threading module now delete self.__block that is
1958 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1959 lock primitives tend to be limited in number and thus should not be wasted on
1960 a _DummyThread object. Fixes bug #1089632.
1961
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001962- The imghdr module now detects Exif files.
1963
Raymond Hettinger6065d322004-12-20 23:51:53 +00001964- StringIO.truncate() now correctly adjusts the size attribute.
1965 (Bug #951915).
1966
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001967- locale.py now uses an updated locale alias table (built using
1968 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1969 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001970 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001971
Raymond Hettinger3557f422004-12-07 12:02:02 +00001972- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1973
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001974- the pickle module no longer accepts the deprecated None option in the
1975 args tuple returned by __reduce__().
1976
Brett Cannon84667c02004-12-07 03:25:18 +00001977- optparse now optionally imports gettext. This allows its use in setup.py.
1978
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001979- the pickle module no longer uses the deprecated bin parameter.
1980
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001981- the shelve module no longer uses the deprecated binary parameter.
1982
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001983- the pstats module no longer uses the deprecated ignore() method.
1984
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001985- the filecmp module no longer uses the deprecated use_statcache argument.
1986
Raymond Hettinger664347b2004-12-04 21:21:53 +00001987- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1988 extended or overridden by subclasses. Formerly, the subclassed method would
1989 be ignored by the rest of the module. (Bug #1078905).
1990
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001991- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001992 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001993
Walter Dörwald36733692004-12-22 12:50:50 +00001994- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1995 once when a size argument is given. This prevents a buffer overflow in the
1996 tokenizer with very long source lines.
1997
Barry Warsaw538561e2006-01-01 21:48:54 +00001998- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1999 immediately after creating the object, without any intervening
2000 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002001
Skip Montanaro05885812005-01-16 20:48:27 +00002002- The reconvert.quote function can now emit triple-quoted strings. The
2003 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002004
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002005- ``UserString.MutableString`` now supports negative indices in
2006 ``__setitem__`` and ``__delitem__``
2007
Greg Ward40407942005-03-05 02:53:17 +00002008- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2009 correctly.
2010
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002011- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2012 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2013 character even if the user has passed a size parameter to get a proper
2014 line ending. Remove the special handling of a "\r\n" that has been split
2015 between two lines.
2016
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002017- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2018 about illegal code points. The codec now supports PEP 293 style error
2019 handlers.
2020
Walter Dörwald78a78b02005-09-01 12:04:29 +00002021- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002022 from the input stream, so that the output is a byte string in the correct
2023 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002024
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002025- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2026 considering it exactly like a '*'.
2027
Walter Dörwald007f8df2005-10-09 19:42:27 +00002028- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2029 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002030
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002031- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2032
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002033- Patch #1413711: Certain patterns of differences were making difflib
2034 touch the recursion limit.
2035
Walter Dörwald58917a62006-03-31 15:26:22 +00002036- Bug #947906: An object oriented interface has been added to the calendar
2037 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002038 called as a script (e.g. via ``python -mcalendar``). Localized month and
2039 weekday names can be ouput (even if an exotic encoding is used) using
2040 special classes that use unicode.

2043-----
2044
Neal Norwitz602d3392006-03-31 08:21:40 +00002045- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2046 by using -mieee gcc option.
2047

2049
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002050- Build support for Win64-AMD64 was added.
2051
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002052- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2053
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002054- Patch #881820: look for openpty and forkpty also in libbsd.
2055
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002056- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2057 The zlib module is now builtin on Windows.
2058
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002059- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2060
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002061- Bug #1189330: configure did not correctly determine the necessary
2062 value of LINKCC if python was built with GCC 4.0.
2063
Trent Mick8321b422005-07-26 02:29:21 +00002064- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2065 vulnerability in zlib 1.2.1 and 1.2.2.
2066
Brett Cannon08cd5982005-04-24 22:26:38 +00002067- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2068 flags that change binary compatibility. Changes were also made to
2069 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002070 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002071
Bob Ippolitoed233462005-03-29 13:47:59 +00002072- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2073 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2074 no longer exists). This configure patch makes things right.
2075
Martin v. Löwise2713be2005-03-08 15:03:08 +00002076- Bug #1158607: Build with --disable-unicode again.
2077
Brett Cannon46d96232005-02-16 00:07:19 +00002078- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2079 defined. Discovered as a result of not being able to build on OS X.
2080
Brett Cannon516592f2004-12-07 00:42:59 +00002081- setup.py now uses the directories specified in LDFLAGS using the -L option
2082 and in CPPFLAGS using the -I option for adding library and include
2083 directories, respectively, for compiling extension modules against. This has
2084 led to the core being compiled using the values in CPPFLAGS. It also removes
2085 the need for the special-casing of both DarwinPorts and Fink for darwin since
2086 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2087 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2088 Fink, ``-I/opt/local/include`` for DarwinPorts).
2089
Brett Cannon43802422005-02-10 20:48:03 +00002090- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2091 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2092 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2093 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002095C API
2096-----
2097
Tim Petersc9d78aa2006-03-26 23:27:58 +00002098- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2099 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2100 is obtained via the ``PyObject_`` family, it must be released via the
2101 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2102 always been officially true, but when Python's small-object allocator was
2103 introduced, an attempt was made to cater to a few extension modules
2104 discovered at the time that obtained memory via ``PyObject_New`` but
2105 released it via ``PyMem_DEL``. It's years later, and if such code still
2106 exists it will fail now (probably with segfaults, but calling wrong
2107 low-level memory management functions can yield many symptoms).
2108
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002109- Added a C API for set and frozenset objects.
2110
Raymond Hettinger66517482004-12-03 11:45:13 +00002111- Removed PyRange_New().
2112
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002113- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2114 mapping argument now. This string is used as a mapping table. Byte values
2115 greater than the length of the string and 0xFFFE are treated as undefined
2116 mappings.

2121
Martin v. Löwis4d394df2005-01-23 09:19:22 +00002122- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002123
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002124- Patch #1276356: New resource "urlfetch" is implemented. This enables
2125 even impatient people to run tests that require remote files.
