13-----------------
14
Neal Norwitz0bcafac2006-09-11 08:51:17 +000015- Make _PyGILState_NoteThreadState() static, it was not used anywhere
16 outside of pystate.c and should not be necessary.
17
Brett Cannon19d76c52006-09-09 07:18:44 +000018- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
19 allows calling unicode() on exceptions classes directly to succeed.
20
Georg Brandlecab6232006-09-06 06:47:02 +000021- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
22 Also make sure that every exception class has __module__ set to
23 'exceptions'.
24
Georg Brandl37a9e572006-09-06 06:09:34 +000025- Bug #1550983: emit better error messages for erroneous relative
26 imports (if not in package and if beyond toplevel package).
27
Tim Peterscbdd3502006-09-05 01:47:53 +000028- Overflow checking code in integer division ran afoul of new gcc
29 optimizations. Changed to be more standard-conforming.

Neal Norwitz29a5fdb2006-09-05 02:21:38 +000036- The return tuple from str.rpartition(sep) is (tail, sep, head) where
37 head is the original string if sep was not found.
38
Neal Norwitz3b3aae02006-09-05 03:56:01 +000039- Bug #1520864: unpacking singleton tuples in list comprehensions and
40 generator expressions (x for x, in ... ) works again. Fixing this problem
41 required changing the .pyc magic number. This means that .pyc files
42 generated before 2.5c2 will be regenerated.

Guido van Rossumc69ac252006-08-10 18:09:25 +0000126What's New in Python 2.5 release candidate 1?
127=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000128
Anthony Baxterb4096662006-08-16 03:42:26 +0000129*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000130
131Core and builtins
132-----------------
133
Neal Norwitz24b6f202006-09-05 04:43:56 +0000134- Fix infinite recursion when subclassing long and overriding __hash__.
135
136- Fix concatenation (+=) of long strings.
137
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000138- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000139 compared equal or unequal to a string and a UnicodeDecodeError
140 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000141
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000142 Instead, the equal (==) and unequal (!=) comparison operators will
143 now issue a UnicodeWarning and interpret the two objects as
144 unequal. The UnicodeWarning can be filtered as desired using
145 the warning framework, e.g. silenced completely, turned into an
146 exception, logged, etc.
147
148 Note that compare operators other than equal and unequal will still
149 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000150
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000151- Fix segfault when doing string formatting on subclasses of long.
152
153- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
154 with new-style classes.
155
156- Fix bug related to __len__ functions returning negative values with
157 classic classes.
158
159- Patch #1538606, Fix __index__() clipping. There were some problems
160 discovered with the API and how integers that didn't fit into Py_ssize_t
161 were handled. This patch attempts to provide enough alternatives
162 to effectively use __index__.
163
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000164- Bug #1536021: __hash__ may now return long int; the final hash
165 value is obtained by invoking hash on the long int.
166
Thomas Hellerab1049c2006-08-08 17:37:00 +0000167- Bug #1536786: buffer comparison could emit a RuntimeWarning.
168
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000169- Bug #1535165: fixed a segfault in input() and raw_input() when
170 sys.stdin is closed.
171
Thomas Heller74d36f02006-08-04 18:17:40 +0000172- On Windows, the PyErr_Warn function is now exported from
173 the Python dll again.
174
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000175- Bug #1191458: tracing over for loops now produces a line event
176 on each iteration. Fixing this problem required changing the .pyc
177 magic number. This means that .pyc files generated before 2.5c1
178 will be regenerated.
179
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000180- Bug #1333982: string/number constants were inappropriately stored
181 in the byte code and co_consts even if they were not used, ie
182 immediately popped off the stack.
183
Georg Brandle9462c72006-08-04 18:03:37 +0000184- Fixed a reference-counting problem in property().
185
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000186
187Library
188-------
189
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000190- Fix a bug in the ``compiler`` package that caused invalid code to be
191 generated for generator expressions.
192
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000193- The distutils version has been changed to 2.5.0. The change to
194 keep it programmatically in sync with the Python version running
195 the code (introduced in 2.5b3) has been reverted. It will continue
196 to be maintained manually as static string literal.
197
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000198- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000199 and this cannot be converted to the required C type, an exception is
200 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000201 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000202
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000203- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000204 an exception.
205
Tim Peterscbdd3502006-09-05 01:47:53 +0000206- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000207 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000208 workarounds for clocks with low resolution, to stop the code yielding
209 duplicate UUIDs.
210
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000211- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
212 before raising SystemExit, allowing IDLE to honor quit() and exit().
213
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000214- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
215
Georg Brandl7a1af772006-08-14 21:55:28 +0000216- Patch #1536071: trace.py should now find the full module name of a
217 file correctly even on Windows.
218
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000219- logging's atexit hook now runs even if the rest of the module has
220 already been cleaned up.
221
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000222- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000223
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000224- Bug #1531405, format_exception no longer raises an exception if
225 str(exception) raised an exception.
226
Neil Schemenauer06ded092006-08-04 16:20:30 +0000227- Fix a bug in the ``compiler`` package that caused invalid code to be
228 generated for nested functions.

240
Thomas Heller1ce433e2006-08-14 16:20:04 +0000241- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
242 '-no-stack-protector' compiler flag for OpenBSD has been removed.
243
Thomas Heller86720042006-08-14 11:17:48 +0000244- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
245 uses the _as_parameter_ attribute when objects are passed to foreign
246 function calls. The ctypes version number was changed to 1.0.1.
247
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000248- Bug #1530559, struct.pack raises TypeError where it used to convert.
249 Passing float arguments to struct.pack when integers are expected
250 now triggers a DeprecationWarning.
251
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000252

Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000303- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000304 returned a long (see PEP 353).
305
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000306- Bug #1515471: string.replace() accepts character buffers again.
307
Neal Norwitz07aadb12006-07-30 06:55:48 +0000308- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
309 This provides the proper warning for struct.pack().
310 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
311
Neal Norwitz0d62a062006-07-30 06:53:31 +0000312- Patch #1531113: Fix augmented assignment with yield expressions.
313 Also fix a SystemError when trying to assign to yield expressions.

Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000315- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
316 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
317 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
318 excessive filesystem operations during imports.
319
Tim Petersbc24eee2006-07-27 01:14:53 +0000320- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
321 operations on signed longs that are formally undefined by C.
322 Unfortunately, at least one compiler now cares about that, so complicated
323 the code to make that compiler happy again.
324
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000325- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
326
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000327- Patch #1232023: Stop including current directory in search
328 path on Windows.
329
Neal Norwitze1fdb322006-07-21 05:32:28 +0000330- Fix some potential crashes found with failmalloc.
331
Neal Norwitze7563102006-07-17 01:00:16 +0000332- Fix warnings reported by Klocwork's static analysis tool.
333
Neal Norwitz84be93b2006-07-16 01:50:38 +0000334- Bug #1512814, Fix incorrect lineno's when code within a function
335 had more than 255 blank lines.
336
Georg Brandl9dceedb2006-07-12 15:31:17 +0000337- Patch #1521179: Python now accepts the standard options ``--help`` and
338 ``--version`` as well as ``/?`` on Windows.
339
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000340- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000341 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000342 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000343
Tim Peters112aad32006-07-19 00:03:19 +0000344- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000345 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000346 new ``sys._current_frames()`` returns a dictionary with one entry,
347 mapping the faux "thread id" 0 to the current frame.
348
Ronald Oussoren3075e162006-07-25 20:28:55 +0000349- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

353-------
354
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000355- Correction of patch #1455898: In the mbcs decoder, set final=False
356 for stream decoder, but final=True for the decode function.
357
Georg Brandl07fec3a2006-08-01 18:49:24 +0000358- os.urandom no longer masks unrelated exceptions like SystemExit or
359 KeyboardInterrupt.
360
Tim Peters4643c2f2006-08-10 22:45:34 +0000361- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000362 shutil.copytree on Windows
363
Georg Brandle34ac7c2006-07-30 11:07:23 +0000364- Bug #1002398: The documentation for os.path.sameopenfile now correctly
365 refers to file descriptors, not file objects.
366
Tim Peterscbdd3502006-09-05 01:47:53 +0000367- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000368 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000369 #1513611, and probably others.
370
Georg Brandledd9b0d2006-07-29 09:33:26 +0000371- Bug #1441397: The compiler module now recognizes module and function
372 docstrings correctly as it did in Python 2.4.
373
Tim Peters6f681472006-07-27 23:44:37 +0000374- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
375 lost that tests are sorted by name before being run. This rarely
376 matters for well-written tests, but can create baffling symptoms if
377 side effects from one test to the next affect outcomes. ``DocTestFinder``
378 has been changed to sort the list of tests it returns.
379
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000380- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000381 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000382
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000383- Bug #978833: Really close underlying socket in _socketobject.close.
384
Georg Brandldb232dc2006-08-20 13:15:43 +0000385- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
386 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000387
Georg Brandlcf0c1722006-07-26 07:23:32 +0000388- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
389 to recursive calls and call it with the failing package name.
390
Martin v. Löwis0b483032006-07-25 09:53:12 +0000391- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
392
Georg Brandlc13c34c2006-07-24 14:09:56 +0000393- Patch #1515343: Fix printing of deprecated string exceptions with a
394 value in the traceback module.
395
Greg Ward48fae7a2006-07-23 16:05:51 +0000396- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
397
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000398- Patch #1524429: Use repr() instead of backticks in Tkinter again.
399
Brett Cannoncaebe222006-07-18 04:41:36 +0000400- Bug #1520914: Change time.strftime() to accept a zero for any position in its
401 argument tuple. For arguments where zero is illegal, the value is forced to
402 the minimum value that is correct. This is to support an undocumented but
403 common way people used to fill in inconsequential information in the time
404 tuple pre-2.4.
405
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000406- Patch #1220874: Update the binhex module for Mach-O.
407
Barry Warsawb110bad2006-07-21 14:51:07 +0000408- The email package has improved RFC 2231 support, specifically for
409 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
410 (name*0=<blah>) parameter continuations. This may change the types of
411 values returned from email.message.Message.get_param() and friends.
412 Specifically in some cases where non-encoded continuations were used,
413 get_param() used to return a 3-tuple of (None, None, string) whereas now it
414 will just return the string (since non-encoded continuations don't have
415 charset and language parts).
416
417 Also, whereas % values were decoded in all parameter continuations, they are
418 now only decoded in encoded parameter parts.
419
Ronald Oussoren3075e162006-07-25 20:28:55 +0000420- Bug #1517990: IDLE keybindings on MacOS X now work correctly
421
422- Bug #1517996: IDLE now longer shows the default Tk menu when a
423 path browser, class browser or debugger is the frontmost window on MacOS X
424
Barry Warsaw00decd72006-07-27 23:43:15 +0000425- Patch #1520294: Support for getset and member descriptors in types.py,
426 inspect.py, and pydoc.py. Specifically, this allows for querying the type
427 of an object against these built-in types and more importantly, for getting
428 their docstrings printed in the interactive interpreter's help() function.

432-----------------
433
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000434- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
435 a socket operation on a socket with a timeout, the exception will be
436 caught correctly. Previously, the exception was not caught.
437
Thomas Heller1393d6a2006-07-28 21:43:20 +0000438- Patch #1529514: The _ctypes extension is now compiled on more
439 openbsd target platforms.
440
Tim Peters9cab5932006-07-28 00:30:00 +0000441- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
442 a memory leak, affecting pickles and deep copies.
443
Tim Petersbc24eee2006-07-27 01:14:53 +0000444- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

446
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000447- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
448
Thomas Hellerce049a02006-07-14 17:51:14 +0000449- Patch #1521817: Index range checking on ctypes arrays containing
450 exactly one element enabled again. This allows iterating over these
451 arrays, without the need to check the array size before.
452
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000453- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000454 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000455 /dev/null in certain cases; this is now fixed.
456
Thomas Heller47d7a062006-07-12 08:43:47 +0000457- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
458 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000459
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000460- Because of a misspelled preprocessor symbol, ctypes was always
461 compiled without thread support; this is now fixed.
462
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000463- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
464 methods now allow their database parameter to be None as the
465 sleepycat API allows.
466
Matt Flemingec926502006-07-28 11:27:27 +0000467- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
468 bluetooth API compared with Linux and FreeBSD.
469
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000470Tests
471-----
472
473- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
474 how long the test file should take to play. Now accepts taking 2.93 secs
475 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
476
Georg Brandl4793aa32006-07-28 18:31:39 +0000477- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
478 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
479 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000486Mac
487---
488
489- PythonLauncher now works correctly when the path to the script contains
490 characters that are treated specially by the shell (such as quotes).
491
492- Bug #1527397: PythonLauncher now launches scripts with the working directory
493 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000494 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000495 expect.

504-----------------
505
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000506- Bug #1441486: The literal representation of -(sys.maxint - 1)
507 again evaluates to a int object, not a long.
508
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000509- Bug #1501934: The scope of global variables that are locally assigned
510 using augmented assignment is now correctly determined.
511
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000512- Bug #927248: Recursive method-wrapper objects can now safely
513 be released.
514
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000515- Bug #1417699: Reject locale-specific decimal point in float()
516 and atof().
517
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000518- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
519 omit a default "error" argument for NULL pointer. This allows
520 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000521
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000522- Bug #1519018: 'as' is now validated properly in import statements.
523
Neal Norwitz28746ab2006-07-09 22:14:42 +0000524- On 64 bit systems, int literals that use less than 64 bits are
525 now ints rather than longs.
526
Neal Norwitzed657552006-07-10 00:04:44 +0000527- Bug #1512814, Fix incorrect lineno's when code at module scope
528 started after line 256.
529
Tim Peters32a83612006-07-10 21:08:24 +0000530- New function ``sys._current_frames()`` returns a dict mapping thread
531 id to topmost thread stack frame. This is for expert use, and is
532 especially useful for debugging application deadlocks. The functionality
533 was previously available in Fazal Majid's ``threadframe`` extension
534 module, but it wasn't possible to do this in a wholly threadsafe way from
535 an extension.

544
Tim Peters32a83612006-07-10 21:08:24 +0000545- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000546 environment variable to be set in order to the SDK environment
547 for finding the compiler, include files, etc.

552
Thomas Woutersadd19112006-07-05 11:03:49 +0000553- string.Template() now correctly handles tuple-values. Previously,
554 multi-value tuples would raise an exception and single-value tuples would
555 be treated as the value they contain, instead.
556
Martin v. Löwisede77f52006-07-03 13:01:35 +0000557- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
558 even if some data are received.
559
Martin v. Löwis45482392006-07-03 12:28:58 +0000560- Bug #1267547: Put proper recursive setup.py call into the

564 degrees and radians.
565
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000566- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000567 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000568
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000569- Bug #1514703: Only setup canvas window in turtle when the canvas
570 is created.
571
Martin v. Löwis7596e832006-07-01 15:33:37 +0000572- Bug #1513223: .close() of a _socketobj now releases the underlying
573 socket again, which then gets closed as it becomes unreferenced.
574
Fred Drake10497c82006-06-29 02:57:48 +0000575- Bug #1504333: Make sgmllib support angle brackets in quoted
576 attribute values.
577
578- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
579 sgmllib ('[' and ']' were not accepted).
580
Georg Brandl1be63af2006-06-28 20:23:25 +0000581- Fix a bug in the turtle module's end_fill function.
582
Brett Cannon53ab5b72006-06-22 16:49:14 +0000583- Bug #1510580: The 'warnings' module improperly required that a Warning
584 category be either a types.ClassType and a subclass of Warning. The proper
585 check is just that it is a subclass with Warning as the documentation states.
586
Georg Brandlad29e632006-06-21 17:45:17 +0000587- The compiler module now correctly compiles the new try-except-finally
588 statement (bug #1509132).
589
Neal Norwitz60373cd2006-06-22 06:30:50 +0000590- The wsgiref package is now installed properly on Unix.
591
Vinay Sajip28e57612006-07-01 10:45:20 +0000592- A bug was fixed in logging.config.fileConfig() which caused a crash on
593 shutdown when fileConfig() was called multiple times.
594
Gerhard Häring762fbd32006-07-02 17:48:30 +0000595- The sqlite3 module did cut off data from the SQLite database at the first
596 null character before sending it to a custom converter. This has been fixed
597 now.

Tim Peters112aad32006-07-19 00:03:19 +0000602- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
603 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
604 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000605
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000606- Assigning None to pointer type fields in ctypes structures possible
607 overwrote the wrong fields, this is fixed now.
608
609- Fixed a segfault in _ctypes when ctypes.wintypes were imported
610 on non-Windows platforms.
611
612- Bug #1518190: The ctypes.c_void_p constructor now accepts any
613 integer or long, without range checking.
614
615- Patch #1517790: It is now possible to use custom objects in the ctypes
616 foreign function argtypes sequence as long as they provide a from_param
617 method, no longer is it required that the object is a ctypes type.
618
619- The '_ctypes' extension module now works when Python is configured
620 with the --without-threads option.
621
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000622- Bug #1513646: os.access on Windows now correctly determines write
623 access, again.
624
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000625- Bug #1512695: cPickle.loads could crash if it was interrupted with
626 a KeyboardInterrupt.
627
Neal Norwitza12aa882006-07-06 06:45:08 +0000628- Bug #1296433: parsing XML with a non-default encoding and
629 a CharacterDataHandler could crash the interpreter in pyexpat.
630
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000631- Patch #1516912: improve Modules support for OpenVMS.

634-----
635
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000636- Automate Windows build process for the Win64 SSL module.
637
Tim Peters32a83612006-07-10 21:08:24 +0000638- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000639 Previously, the slight difference could cause compilation errors of the
640 'zlib' module on systems with more than one version of zlib.
641
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000642- The MSI compileall step was fixed to also support a TARGETDIR
643 with spaces in it.
644
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000645- Bug #1517388: sqlite3.dll is now installed on Windows independent
646 of Tcl/Tk.
647
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000648- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000649 trying to be installed even though it's empty.

652-----
653
654- Call os.waitpid() at the end of tests that spawn child processes in order
655 to minimize resources (zombies).
656
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000657Documentation
658-------------
659
Nick Coghlan2d792252006-07-06 13:47:18 +0000660- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
661 documentation for the warnings module.
662
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000663- Patch #1509163: MS Toolkit Compiler no longer available.
664
Neal Norwitz56640df2006-07-10 02:36:41 +0000665- Patch #1504046: Add documentation for xml.etree.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000670
Anthony Baxterd1136802006-06-19 12:04:15 +0000671*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000672
673Core and builtins
674-----------------
675
Georg Brandla56b9152006-06-19 06:35:54 +0000676- Patch #1507676: Error messages returned by invalid abstract object operations
677 (such as iterating over an integer) have been improved and now include the
678 type of the offending object to help with debugging.
679
Brett Cannonea3912b2006-06-13 21:46:41 +0000680- Bug #992017: A classic class that defined a __coerce__() method that returned
681 its arguments swapped would infinitely recurse and segfault the interpreter.
682
Neal Norwitz909eb122006-06-12 02:13:21 +0000683- Fix the socket tests so they can be run concurrently.
684
Neal Norwitzb9845e72006-06-12 02:11:18 +0000685- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000686 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000687
Brett Cannon22565aa2006-06-09 22:31:23 +0000688- Bug #532646: object.__call__() will continue looking for the __call__
689 attribute on objects until one without one is found. This leads to recursion
690 when you take a class and set its __call__ attribute to an instance of the
691 class. Originally fixed for classic classes, but this fix is for new-style.
692 Removes the infinite_rec_3 crasher.
693
Georg Brandl24250812006-06-09 18:45:48 +0000694- The string and unicode methods startswith() and endswith() now accept
695 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
696
Brett Cannonde3b0522006-06-08 17:00:45 +0000697- Buffer objects, at the C level, never used the char buffer
698 implementation even when the char buffer for the wrapped object was
699 explicitly requested (originally returned the read or write buffer).
700 Now a TypeError is raised if the char buffer is not present but is
701 requested.
702
Georg Brandlddbaa662006-06-04 21:56:52 +0000703- Patch #1346214: Statements like "if 0: suite" are now again optimized
704 away like they were in Python 2.4.
705
Georg Brandlb7c8f542006-05-27 12:30:25 +0000706- Builtin exceptions are now full-blown new-style classes instead of
707 instances pretending to be classes, which speeds up exception handling
708 by about 80% in comparison to 2.5a2.
709
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000710- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
711 Unicode 4.1.
712
Georg Brandlf4ef1162006-05-26 18:03:31 +0000713- Patch #921466: sys.path_importer_cache is now used to cache valid and
714 invalid file paths for the built-in import machinery which leads to
715 fewer open calls on startup.
716
Tim Peters696cf432006-05-24 21:10:40 +0000717- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
718 of-2 bases. The largest speedup is for inputs with about 1000 decimal
719 digits. Conversion from non-power-of-2 bases remains quadratic-time in
720 the number of input digits (it was and remains linear-time for bases
721 2, 4, 8, 16 and 32).
722
Tim Petersb713ec22006-05-23 18:45:30 +0000723- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
724 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
725 an integer close to ``sys.maxint``. This was repaired by patch
726 #1335972, which also gives a nice speedup.
727
Richard Jonescebbefc2006-05-23 18:28:17 +0000728- Patch #1337051: reduced size of frame objects.
729
730- PyErr_NewException now accepts a tuple of base classes as its
731 "base" parameter.
732
Richard Jones7c88dcc2006-05-23 10:37:38 +0000733- Patch #876206: function call speedup by retaining allocated frame
734 objects.
735
Georg Brandl7b90e162006-05-18 07:01:27 +0000736- Bug #1462152: file() now checks more thoroughly for invalid mode
737 strings and removes a possible "U" before passing the mode to the
738 C library function.
739
Neal Norwitz1004a532006-05-15 07:17:23 +0000740- Patch #1488312, Fix memory alignment problem on SPARC in unicode
741
Neal Norwitz373f0a72006-05-15 07:04:36 +0000742- Bug #1487966: Fix SystemError with conditional expression in assignment
743
Martin v. Löwis879768d2006-05-11 13:28:43 +0000744- WindowsError now has two error code attributes: errno, which carries
745 the error values from errno.h, and winerror, which carries the error
746 values from winerror.h. Previous versions put the winerror.h values
747 (from GetLastError()) into the errno attribute.
748
Martin v. Löwis77736712006-05-04 05:51:03 +0000749- Patch #1475845: Raise IndentationError for unexpected indent.
750
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000751- Patch #1479181: split open() and file() from being aliases for each other.
752
Tim Peters44bd9862006-06-01 13:49:23 +0000753- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
754 methods were always silently ignored by dictionaries when comparing keys.
755 They are now passed through (except when using the C API function
756 ``PyDict_GetItem()``, whose semantics did not change).
757
758- Bug #1456209: In some obscure cases it was possible for a class with a
759 custom ``__eq__()`` method to confuse dict internals when class instances
760 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
761 No, you don't have any code that did this ;-)

767
768- Patch #1462338: Upgrade pyexpat to expat 2.0.0
769
Brett Cannon6ee7d012006-06-08 16:23:04 +0000770- Change binascii.hexlify to accept a read-only buffer instead of only a char
771 buffer and actually follow its documentation.
772
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000773- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
774
Nick Coghlanc649ec52006-05-29 12:43:05 +0000775- Patch #1478788 (modified version): The functional extension module has
776 been renamed to _functools and a functools Python wrapper module added.
777 This provides a home for additional function related utilities that are
778 not specifically about functional programming. See PEP 309.
779
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000780- Patch #1493701: performance enhancements for struct module.
781
Georg Brandl378d5922006-05-17 14:26:50 +0000782- Patch #1490224: time.altzone is now set correctly on Cygwin.
783
Georg Brandl8d3342b2006-05-16 07:38:27 +0000784- Patch #1435422: zlib's compress and decompress objects now have a
785 copy() method.
786
Andrew MacIntyre92913322006-06-13 15:04:24 +0000787- Patch #1454481: thread stack size is now tunable at runtime for thread
788 enabled builds on Windows and systems with Posix threads support.
789
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000790- On Win32, os.listdir now supports arbitrarily-long Unicode path names
791 (up to the system limit of 32K characters).
792
793- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
794 As a result, these functions now raise WindowsError instead of OSError.
795
Tim Peters7a822da2006-05-25 21:50:17 +0000796- ``time.clock()`` on Win64 should use the high-performance Windows
797 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
798 Windows platforms).
799
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000800- Calling Tk_Init twice is refused if the first call failed as that
801 may deadlock.
802
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000803- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
804 accept it without potentially using an uninitialized pointer.
805
806- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
807 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
808 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000809
Gregory P. Smith372b5832006-06-05 18:48:21 +0000810- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000811 [pybsddb project SF patch number 1466734]
812
Gregory P. Smith372b5832006-06-05 18:48:21 +0000813- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
814 parameter is supplied. [SF pybsddb bug #1477863]
815
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000816- bsddb: the __len__ method of a DB object has been fixed to return correct
817 results. It could previously incorrectly return 0 in some cases.
818 Fixes SF bug 1493322 (pybsddb bug 1184012).
819
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000820- bsddb: the bsddb.dbtables Modify method now raises the proper error and
821 aborts the db transaction safely when a modifier callback fails.
822 Fixes SF python patch/bug #1408584.
823
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000824- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000825 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000826 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
827 database calls that would previously deadlock. [SF python bug #775414]
828
Vinay Sajip28e57612006-07-01 10:45:20 +0000829- Patch #1446489: add support for the ZIP64 extensions to zipfile.

Walter Dörwald4994d952006-06-19 08:07:50 +0000831- Patch #1506645: add Python wrappers for the curses functions
832 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000833
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000834Library
835-------
836
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000837- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
838 functions.
839
Martin v. Löwis3798da02006-06-17 18:44:27 +0000840- Patch #812986: Update turtle output even if not tracing.
841
Vinay Sajip28e57612006-07-01 10:45:20 +0000842- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000843 Tkinter.BaseWidget.
844
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000845- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
846
Martin v. Löwis337487e2006-06-17 09:15:14 +0000847- Patch #763580: Add name and value arguments to Tkinter variable
848 classes.
849
Georg Brandl83cc0d02006-06-14 08:50:03 +0000850- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
851 mime.types file for determining MIME types.
852
Georg Brandl2605ca82006-06-14 06:08:31 +0000853- Bug #1339007: Shelf objects now don't raise an exception in their
854 __del__ method when initialization failed.
855
Martin v. Löwisd8251432006-06-14 05:21:04 +0000856- Patch #1455898: The MBCS codec now supports the incremental mode for
857 double-byte encodings.
858
Tim Peters43898b42006-06-14 04:09:25 +0000859- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
860 guarantee that adjacent triples in the return list always describe
861 non-adjacent blocks. Previously, a pair of matching blocks could end
862 up being described by multiple adjacent triples that formed a partition
863 of the matching pair.
864
Greg Ward0e0c9f42006-06-11 16:24:11 +0000865- Bug #1498146: fix optparse to handle Unicode strings in option help,
866 description, and epilog.
867
Greg Wardd1c797e2006-06-11 14:42:41 +0000868- Bug #1366250: minor optparse documentation error.
869
Greg Ward7f547402006-06-11 00:40:49 +0000870- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
871 clarify docs.
872
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000873- The wsgiref package has been added to the standard library.
874
Nick Coghlan676725d2006-06-08 13:54:49 +0000875- The functions update_wrapper() and wraps() have been added to the functools
876 module. These make it easier to copy relevant metadata from the original
877 function when writing wrapper functions.
878
Tim Petersd6a9eef2006-06-05 01:48:21 +0000879- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
880 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000881
Martin v. Löwis3f767792006-06-04 19:36:28 +0000882- Patch #1359618: Speed up charmap encoder by using a trie structure
883 for lookup.
884
Tim Petersd609b1a2006-06-02 23:22:51 +0000885- The functions in the ``pprint`` module now sort dictionaries by key
886 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
887 if and only if its display required more than one line, although that
888 wasn't documented. The new behavior increases predictability; e.g.,
889 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
890
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000891- Patch #1497027: try HTTP digest auth before basic auth in urllib2
892 (thanks for J. J. Lee).
893
Georg Brandl2b330372006-05-28 20:23:12 +0000894- Patch #1496206: improve urllib2 handling of passwords with respect to
895 default HTTP and HTTPS ports.
896
George Yoshidaf3c65de2006-05-28 16:39:09 +0000897- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
898
Bob Ippolito7298f272006-05-23 18:43:47 +0000899- Patch #1281707: speed up gzip.readline.
900
Georg Brandlb89316f2006-05-17 15:51:16 +0000901- Patch #1180296: Two new functions were added to the locale module:
902 format_string() to get the effect of "format % items" but locale-aware,
903 and currency() to format a monetary number with currency sign.
904
Georg Brandle3a25832006-05-17 14:56:04 +0000905- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
906 and several features added, such as speed and geometry control.
907
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000908- Patch #1488881: add support for external file objects in bz2 compressed
909 tarfiles.
910
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000911- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
912 stdout arguments, making it possible to redirect input and output
913 for remote debugging.
914
915- Patch #1484695: Update the tarfile module to version 0.8. This fixes
916 a couple of issues, notably handling of long file names using the
917 GNU LONGNAME extension.
918
919- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
920 new flag when ``name`` is already the name of an option flag.
921
922- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
923 package.
924
925- Patch #1472854: make the rlcompleter.Completer class usable on non-
926 UNIX platforms.
927
928- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
929
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000930- Bug #1472827: correctly escape newlines and tabs in attribute values in
931 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000961What's New in Python 2.5 alpha 2?
962=================================
963
964*Release date: 27-APR-2006*
965
966Core and builtins
967-----------------
968
Thomas Heller1b046642006-04-18 18:51:06 +0000969- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
970 by converting these apis from macros into exported functions again:
971
972 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
973 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
974 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
975 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
976 PyRun_String Py_CompileString
977
Martin v. Löwis45294a92006-04-18 06:24:08 +0000978- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
979
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000980- All uses of PyStructSequence_InitType have been changed to initialize
981 the type objects only once, even if the interpreter is initialized
982 multiple times.
983
Neal Norwitz61546162006-04-14 05:20:28 +0000984- Bug #1454485, array.array('u') could crash the interpreter. This was
985 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
986 to unicode when it didn't make sense. 'u#' now requires a unicode string.
987
988- Py_UNICODE is unsigned. It was always documented as unsigned, but
989 due to a bug had a signed value in previous versions.
990
Tim Peters3a5e8b12006-04-11 01:44:07 +0000991- Patch #837242: ``id()`` of any Python object always gives a positive
992 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
993 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000994 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000995 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000996
Tim Peters3a5e8b12006-04-11 01:44:07 +0000997 def __hash__(self):
998 return id(self) # WRONG
999
1000 because a hash result must be a (short) Python int but it was always
1001 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001002 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001003 was always usable as a hash value before this patch. That's no longer
1004 necessarily so.
1005
1006- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001007 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001008 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001009 #1454844)
1010
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001011- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1012 involving generators that have paused outside of any ``try`` or ``with``
1013 blocks. (In 2.5a1, a paused generator that was part of a reference
1014 cycle could not be garbage collected, regardless of whether it was
1015 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +00001017Extension Modules
1018-----------------
1019
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001020- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1021 is a macro.
1022
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001023- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1024 fails with an error condition.
1025
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001026- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1027
1028- Bug #1117761: bsddb.*open() no longer raises an exception when using
1029 the cachesize parameter.
1030
1031- Bug #1149413: bsddb.*open() no longer raises an exception when using
1032 a temporary db (file=None) with the 'n' flag to truncate on open.
1033
1034- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1035 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001036
Armin Rigoa9017c32006-04-19 11:50:27 +00001037- Patch #1062014: AF_UNIX sockets under Linux have a special
1038 abstract namespace that is now fully supported.
1039
Anthony Baxter51bcb682006-04-05 14:51:42 +00001040Library
1041-------
1042
Peter Astrand7d1d4362006-07-14 14:04:45 +00001043- Bug #1223937: subprocess.CalledProcessError reports the exit status
1044 of the process using the returncode attribute, instead of
1045 abusing errno.
1046
Tim Peters711bf302006-04-25 03:31:36 +00001047- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1048 a doctest to be skipped (the code is not run, and the expected output
1049 or exception is ignored).
1050
Nick Coghlanda2268f2006-04-24 04:37:15 +00001051- Fixed contextlib.nested to cope with exceptions being raised and
1052 caught inside exit handlers.
1053
Greg Wardab05edc2006-04-23 03:47:58 +00001054- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1055 hex, octal, or binary; add ``append_const`` action; keep going if
1056 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1057 added ``epilog`` for better help generation).
1058
Tim Peters21fbd572006-04-21 21:18:10 +00001059- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1060 called from a thread spawned as a side effect of importing a module.
1061
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001062- The pydoc module now supports documenting packages contained in
1063 .zip or .egg files.
1064
1065- The pkgutil module now has several new utility functions, such
1066 as ``walk_packages()`` to support working with packages that are either
1067 in the filesystem or zip files.
1068
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001069- The mailbox module can now modify and delete messages from
1070 mailboxes, in addition to simply reading them. Thanks to Gregory
1071 K. Johnson for writing the code, and to the 2005 Google Summer of
1072 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001073
Tim Petersc7605f22006-04-17 21:12:33 +00001074- The ``__del__`` method of class ``local`` in module ``_threading_local``
1075 returned before accomplishing any of its intended cleanup.
1076
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001077- Patch #790710: Add breakpoint command lists in pdb.
1078
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001079- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +00001081- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1082
Anthony Baxtere29002c2006-04-12 12:07:31 +00001083- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1084 Windows. Bug #1469163.
1085
Phillip J. Eby47032112006-04-11 01:07:43 +00001086- The warnings, linecache, inspect, traceback, site, and doctest modules
1087 were updated to work correctly with modules imported from zipfiles or
1088 via other PEP 302 __loader__ objects.
1089
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001090- Patch #1467770: Reduce usage of subprocess._active to processes which
1091 the application hasn't waited on.
1092
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001093- Patch #1462222: Fix Tix.Grid.
1094
Neal Norwitza31bf182006-04-09 03:35:43 +00001095- Fix exception when doing glob.glob('anything*/')
1096
Skip Montanaro262fb922006-04-21 02:31:07 +00001097- The pstats.Stats class accepts an optional stream keyword argument to
1098 direct output to an alternate file-like object.
1099

1101-----
1102
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001103- The Makefile now has a reindent target, which runs reindent.py on
1104 the library.
1105
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001106- Patch #1470875: Building Python with MS Free Compiler
1107
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001108- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001109
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001110- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1111 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001112 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001113 CXX from --with-cxx-main, see description in README.
1114
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001115- Patch #1429775: Link extension modules with the shared libpython.
1116
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001117- Fixed a libffi build problem on MIPS systems.
1118
Tim Peters8931ff12006-05-13 23:28:20 +00001119- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1120 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1121 and "%zu" for unsigned integers of type ``size_t``.
1122
Anthony Baxter51bcb682006-04-05 14:51:42 +00001123Tests
1124-----
1125
Nick Coghlanda2268f2006-04-24 04:37:15 +00001126- test_contextlib now checks contextlib.nested can cope with exceptions
1127 being raised and caught inside exit handlers.
1128
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001129- test_cmd_line now checks operation of the -m and -c command switches
1130
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001131- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1132 it separately and by hand. It also wasn't cleaning up its changes to
1133 the current Decimal context.
1134
Thomas Woutersabd08882006-04-26 15:53:30 +00001135- regrtest.py now has a -M option to run tests that test the new limits of
1136 containers, on 64-bit architectures. Running these tests is only sensible
1137 on 64-bit machines with more than two gigabytes of memory. The argument
1138 passed is the maximum amount of memory for the tests to use.

1147-------------
1148
Tim Petersb06d28c2006-05-12 01:57:59 +00001149- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1150
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001151- PEP 343: Added Context Types section to the library reference
1152 and attempted to bring other PEP 343 related documentation into
1153 line with the implementation and/or python-dev discussions.
1154
Tim Peters8dc73d22006-04-24 02:03:16 +00001155- Bug #1337990: clarified that ``doctest`` does not support examples
1156 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001159What's New in Python 2.5 alpha 1?
1160=================================
1161
Anthony Baxterebed3f62006-04-03 15:03:44 +00001162*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001163
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001164Core and builtins
1165-----------------
1166
Nick Coghlan43832302006-04-23 17:04:07 +00001167- PEP 338: -m command line switch now delegates to runpy.run_module
1168 allowing it to support modules in packages and zipfiles
1169
Martin v. Löwisc661b882006-04-20 04:54:23 +00001170- On Windows, .DLL is not an accepted file name extension for
1171 extension modules anymore; extensions are only found if they
1172 end in .PYD.
1173
Martin v. Löwisea62d252006-04-03 10:56:49 +00001174- Bug #1421664: sys.stderr.encoding is now set to the same value as
1175 sys.stdout.encoding.
1176
Neal Norwitz92e212f2006-04-03 04:48:37 +00001177- __import__ accepts keyword arguments.
1178
Georg Brandlccadf842006-03-31 18:54:53 +00001179- Patch #1460496: round() now accepts keyword arguments.
1180
Anthony Baxter262c00a2006-03-30 10:53:17 +00001181- Fixed bug #1459029 - unicode reprs were double-escaped.
1182
Hye-Shik Changd478f342006-03-23 12:32:36 +00001183- Patch #1396919: The system scope threads are reenabled on FreeBSD
1184 5.4 and later versions.
1185
Neal Norwitze98ccf62006-03-23 05:39:47 +00001186- Bug #1115379: Compiling a Unicode string with an encoding declaration
1187 now gives a SyntaxError.
1188
Georg Brandlabd1ff82006-03-18 07:59:59 +00001189- Previously, Python code had no easy way to access the contents of a
1190 cell object. Now, a ``cell_contents`` attribute has been added
1191 (closes patch #1170323).
1192
Tim Peterscf79aac2006-03-16 01:14:46 +00001193- Patch #1123430: Python's small-object allocator now returns an arena to
1194 the system ``free()`` when all memory within an arena becomes unused
1195 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1196 freed. Some applications will see a drop in virtual memory size now,
1197 especially long-running applications that, from time to time, temporarily
1198 use a large number of small objects. Note that when Python returns an
1199 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001200 platform C library will in turn return that memory to the operating system.
1201 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001202 appears to be effective at least on Microsoft C and gcc-based systems.
1203 Thanks to Evan Jones for hard work and patience.
1204
Georg Brandl533ff6f2006-03-08 18:09:27 +00001205- Patch #1434038: property() now uses the getter's docstring if there is
1206 no "doc" argument given. This makes it possible to legitimately use
1207 property() as a decorator to produce a read-only property.
1208
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001209- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1210 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1211 of requiring an int or long in slicing and a few other contexts, enabling
1212 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1213
Neal Norwitz995acdf2006-03-07 05:01:00 +00001214- Fixed various bugs reported by Coverity's Prevent tool.
1215
Brett Cannonbf364092006-03-01 04:25:17 +00001216- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1217 new exception base class, BaseException, which has a new message attribute.
1218 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1219 Raising a string exception now raises a DeprecationWarning.
1220
Thomas Woutersfb609f42006-02-28 16:37:25 +00001221- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1222 explicitly relative, using 'from .module import name' to mean 'from the same
1223 package as this module is in. Imports without dots still default to the
1224 old relative-then-absolute, unless 'from __future__ import
1225 absolute_import' is used.
1226
Brett Cannona7446e32006-02-27 23:39:10 +00001227- Properly check if 'warnings' raises an exception (usually when a filter set
1228 to "error" is triggered) when raising a warning for raising string
1229 exceptions.
1230
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001231- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001232 The name was removed from Include/code.h.
1233
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001234- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001235
Guido van Rossum1968ad32006-02-25 22:38:04 +00001236- Patch 1433928:
1237 - The copy module now "copies" function objects (as atomic objects).
1238 - dict.__getitem__ now looks for a __missing__ hook before raising
1239 KeyError.
1240
Tim Peters84ef21c2006-02-28 20:39:06 +00001241- PEP 343: with statement implemented. Needs ``from __future__ import
1242 with_statement``. Use of 'with' as a variable will generate a warning.
1243 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001244 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001245 The following objects have __context__ methods:
1246 - The built-in file type.
1247 - The thread.LockType type.
1248 - The following types defined by the threading module:
1249 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1250 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001251
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001252- Fix the encodings package codec search function to only search
1253 inside its own package. Fixes problem reported in patch #1433198.
1254
1255 Note: Codec packages should implement and register their own
1256 codec search function. PEP 100 has the details.
1257
Tim Peters9ea89d22006-06-04 03:26:02 +00001258- PEP 353: Using ``Py_ssize_t`` as the index type.
1259
1260- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1261 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1262 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1263 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1264 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001265
Neal Norwitzfc76d632006-01-10 06:03:13 +00001266- Patch #1400181, fix unicode string formatting to not use the locale.
1267 This is how string objects work. u'%f' could use , instead of .
1268 for the decimal point. Now both strings and unicode always use periods.
1269
Neal Norwitz671b9e32006-01-09 07:07:12 +00001270- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1271 configure would break checking curses.h.
1272
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001273- Bug #959576: The pwd module is now builtin. This allows Python to be
1274 built on UNIX platforms without $HOME set.
1275
Neal Norwitzc10978f2005-12-19 06:07:16 +00001276- Bug #1072182, fix some potential problems if characters are signed.
1277
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001278- Bug #889500, fix line number on SyntaxWarning for global declarations.
1279
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001280- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1281
Neal Norwitze7214a12005-12-18 05:03:17 +00001282- Support for converting hex strings to floats no longer works.
1283 This was not portable. float('0x3') now raises a ValueError.
1284
Barry Warsaw2a38a862005-12-18 01:27:35 +00001285- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001286 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001287 is now displayed in interactive prompt banner.
1288
Georg Brandlfa166682005-12-17 21:45:17 +00001289- Implementation of PEP 341 - Unification of try/except and try/finally.
1290 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001291 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001292
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001293- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1294 now encodes backslash correctly.
1295
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001296- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1297
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001298- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001299 and long longs.
1300
Neal Norwitz67715f02005-11-09 06:59:35 +00001301- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001302 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001303 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001304
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001305- Replaced most Unicode charmap codecs with new ones using the
1306 new Unicode translate string feature in the builtin charmap
1307 codec; the codecs were created from the mapping tables available
1308 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1309 encodings now include a mapping for the Apple logo)
1310
Tim Peterse3547fd2005-12-16 23:13:57 +00001311- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001312
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001313- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001314
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001315- A new AST parser implementation was completed. The abstract
1316 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001317 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001318
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001319- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001320 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1321
Neal Norwitz708e51a2005-10-03 04:48:15 +00001322- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1323
Neal Norwitz11bd1192005-10-03 00:54:56 +00001324- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1325 Provide a warning when a directory is passed on the command line.
1326
Neal Norwitz40d37812005-10-02 01:48:49 +00001327- Fix segfault with invalid coding.
1328
1329- SF bug #772896: unknown encoding results in MemoryError.
1330
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001331- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001332 supported a __len__() method which evaluated to False when the iterator
1333 was empty.
1334
Guido van Rossum630db602005-09-20 18:49:54 +00001335- On 64-bit platforms, when __len__() returns a value that cannot be
1336 represented as a C int, raise OverflowError.
1337
Skip Montanarof8948ca2005-09-19 03:54:46 +00001338- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001339 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001340
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001341- SF bug #893549: parsing keyword arguments was broken with a few format
1342 codes.
1343
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001344- Changes donated by Elemental Security to make it work on AIX 5.3
1345 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1346 bug #105470: test_pwd fails on 64bit system (Opteron).
1347
Guido van Rossum539c6622005-09-14 17:49:54 +00001348- Changes donated by Elemental Security to make it work on HP-UX 11 on
1349 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1350
Georg Brandl4550b8d2005-08-26 06:43:52 +00001351- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001352 (fixes bug #1119418).
1353
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001354- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1355
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001356- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1357 exceptions that cause a function to exit.
1358
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001359- The implementation of set() and frozenset() was revised to use its
1360 own internal data structure. Memory consumption is reduced by 1/3
1361 and there are modest speed-ups as well. The API is unchanged.
1362
Tim Petersde7990b2005-07-17 23:45:23 +00001363- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1364
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001365- SF bug #1229429: PyObject_CallMethod failed to decrement some
1366 reference counts in some error exit cases.
1367
Tim Petersecc6e6a2005-07-10 22:30:55 +00001368- SF bug #1185883: Python's small-object memory allocator took over
1369 a block managed by the platform C library whenever a realloc specified
1370 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001371 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001372 portable way to copy data from the C-managed block into Python's
1373 small-object space without risking a memory fault. Python's small-object
1374 realloc now leaves such blocks under the control of the platform C
1375 realloc.
1376
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001377- SF bug #1232517: An overflow error was not detected properly when
1378 attempting to convert a large float to an int in os.utime().
1379
Raymond Hettinger3296e692005-06-29 23:29:56 +00001380- SF bug #1224347: hex longs now print with lowercase letters just
1381 like their int counterparts.
1382
Michael W. Hudson188d4362005-06-20 16:52:57 +00001383- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1384 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1385 interpreter states; back out that fix and do a better job (see
1386 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1387 for a longer write-up of the problem).
1388
Michael W. Hudsondf888462005-06-03 14:41:55 +00001389- SF patch #1180995: marshal now uses a binary format by default when
1390 serializing floats.
1391
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001392- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1393 the routines that promise to produce IEEE 754 binary representations
1394 of floats now simply copy bytes around.
1395
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001396- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1397 278.
1398
Brett Cannonc3647ac2005-04-26 03:45:26 +00001399- patch #1109424: int, long, float, complex, and unicode now check for the
1400 proper magic slot for type conversions when subclassed. Previously the
1401 magic slot was ignored during conversion. Semantics now match the way
1402 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001403 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001404 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001405 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001406
Barry Warsawc8d907c2005-04-19 23:43:40 +00001407- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1408 NULL, now raise an AttributeError when attempting to set or delete the
1409 attribute. Previously a TypeError was raised, but this was inconsistent
1410 with the equivalent pure-Python implementation.
1411
Michael W. Hudson774479c2005-04-18 08:46:17 +00001412- It is now safe to call PyGILState_Release() before
1413 PyEval_InitThreads() (note that if there is reason to believe there
1414 are multiple threads around you still must call PyEval_InitThreads()
1415 before using the Python API; this fix is for extension modules that
1416 have no way of knowing if Python is multi-threaded yet).
1417
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001418- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1419 disabled caused a crash.
1420
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001421- Bug #1165306: instancemethod_new allowed the creation of a method
1422 with im_class == im_self == NULL, which caused a crash when called.
1423
Tim Petersecc6e6a2005-07-10 22:30:55 +00001424- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001425 fixes the crash seen in bug #1165761
1426
Raymond Hettinger96229b12005-03-11 06:49:40 +00001427- Added two new builtins, any() and all().
1428
Brett Cannon409d8f22005-03-05 06:47:57 +00001429- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001430 (e.g., ``class C(): pass`` is no longer a syntax error).
1431 Patch #1176012 added support to the 'parser' module and 'compiler' package
1432 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001433
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001434- Patch #1115086: Support PY_LONGLONG in structmember.
1435
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001436- Bug #1155938: new style classes did not check that __init__() was
1437 returning None.
1438
Tim Petersecc6e6a2005-07-10 22:30:55 +00001439- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001440 ('\') with a specific error message.
1441
Martin v. Löwisff232d72005-03-03 09:24:38 +00001442- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1443
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001444- Bug #1124295: the __name__ attribute of file objects was
1445 inadvertently made inaccessible in restricted mode.
1446
Tim Petersecc6e6a2005-07-10 22:30:55 +00001447- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001448 an ferror() call.
1449
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001450- min() and max() now support key= arguments with the same meaning as in
1451 list.sort().
1452
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001453- The peephole optimizer now performs simple constant folding in expressions:
1454 (2+3) --> (5).
1455
Raymond Hettingera422c342005-01-11 03:03:27 +00001456- set and frozenset objects can now be marshalled. SF #1098985.
1457
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001458- Bug #1077106: Poor argument checking could cause memory corruption
1459 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001460
Jeremy Hyltonab630502005-02-04 18:44:06 +00001461- The parser did not complain about future statements in illegal
1462 positions. It once again reports a syntax error if a future
1463 statement occurs after anything other than a doc string.
1464
Neil Schemenauercf52c072005-08-12 17:34:58 +00001465- Change the %s format specifier for str objects so that it returns a
1466 unicode instance if the argument is not an instance of basestring and
1467 calling __str__ on the argument returns a unicode instance.
1468
Tim Petersf4e69282006-02-27 17:15:31 +00001469- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1470 current thread state when the auto-GIL-state machinery knows about
1471 it (since the thread state is being deleted, continuing to remember it
1472 can't help, but can hurt if another thread happens to get created with
1473 the same thread id).
1474
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001475Extension Modules
1476-----------------
1477
Georg Brandl43f08a82006-03-31 18:01:16 +00001478- Patch #1380952: fix SSL objects timing out on consecutive read()s
1479
Neal Norwitz05a45592006-03-20 06:30:08 +00001480- Patch #1309579: wait3 and wait4 were added to the posix module.
1481
Anthony Baxterfa869072006-03-20 05:21:58 +00001482- Patch #1231053: The audioop module now supports encoding/decoding of alaw.

1651
Raymond Hettingerb2594052004-12-05 09:25:51 +00001652- itertools.islice() now accepts None for the start and step arguments.
1653 This allows islice() to work more readily with slices:
1654 islice(s.start, s.stop, s.step)
1655
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001656- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001665- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1666 been renamed to have only a single underscore prefix. This was done to
1667 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001668
Nick Coghlan43832302006-04-23 17:04:07 +00001669- PEP 338: new module runpy defines a run_module function to support
1670 executing modules which provide access to source code or a code object
1671 via the PEP 302 import mechanisms.
1672
Anthony Baxter93f5b932006-04-03 08:05:07 +00001673- The email module's parsedate_tz function now sets the daylight savings

1681 in attribute values.
1682
Anthony Baxterc51ee692006-04-01 00:57:31 +00001683- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001684 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001685 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001686 module will not be built.
1687
Tim Petersc17976e2006-04-01 00:26:53 +00001688- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1689 aren't officially supported here, and trying to use them will probably
1690 raise an exception some day. But dicts have been allowed, and "mostly
1691 worked", so support for them won't go away without warning.
1692
Georg Brandl338ef7d2006-03-31 18:42:16 +00001693- Bug #1445068: getpass.getpass() can now be given an explicit stream
1694 argument to specify where to write the prompt.
1695

1711
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001712- email 4.0 package now integrated. This is largely the same as the email 3.0
1713 package that was included in Python 2.3, except that PEP 8 module names are
1714 now used (e.g. mail.message instead of email.Message). The MIME classes
1715 have been moved to a subpackage (e.g. email.mime.text instead of
1716 email.MIMEText). The old names are still supported for now. Several
1717 deprecated Message methods have been removed and lots of bugs have been
1718 fixed. More details can be found in the email package documentation.
1719
Walter Dörwald40108c92006-03-27 08:15:44 +00001720- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1721 (a subclass of tuple) that provides incremental decoders and encoders
1722 (a way to use stateful codecs without the stream API). Python functions
1723 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1724 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1725 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001727- Patch #1359365: Calling next() on a closed StringIO.String object raises
1728 a ValueError instead of a StopIteration now (like file and cString.String do).
1729 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1730 called before (like file and StringIO.StringIO do).

1806 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1807 Ronald L. Rivest offered this advice for Python:
1808
1809 "The consensus of researchers in this area (at least as
1810 expressed at the NIST Hash Function Workshop 10/31/05),
1811 is that SHA-256 is a good choice for the time being, but
1812 that research should continue, and other alternatives may
1813 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001814

1995 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001996 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001997 PEP 305.

2001 dictates.
2002 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002003 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002004 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002005 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2006 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002007 + reader now allows \r characters to be quoted (previously it only allowed
2008 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002009 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002010 + Dialect classes passed to the module are no longer instantiated by
2011 the module before being parsed (the former validation scheme required
2012 this, but the mechanism was unreliable).
2013 + The dialect registry now contains instances of the internal
2014 C-coded dialect type, rather than references to python objects.
2015 + the internal c-coded dialect type is now immutable.
2016 + register_dialect now accepts the same keyword dialect specifications
2017 as the reader and writer, allowing the user to register dialects
2018 without first creating a dialect class.
2019 + a configurable limit to the size of parsed fields has been added -
2020 previously, an unmatched quote character could result in the entire
2021 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002022 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002023 the parser field size limit (returning the former limit). The initial
2024 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002025 + A line_num attribute has been added to the reader object, which tracks
2026 the number of lines read from the source iterator. This is not
2027 the same as the number of records returned, as records can span
2028 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002029 + reader and writer objects were not being registered with the cyclic-GC.
2030 This has been fixed.
2031
Brett Cannone6539c42005-01-08 02:43:53 +00002032- _DummyThread objects in the threading module now delete self.__block that is
2033 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2034 lock primitives tend to be limited in number and thus should not be wasted on
2035 a _DummyThread object. Fixes bug #1089632.
2036
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002037- The imghdr module now detects Exif files.
2038
Raymond Hettinger6065d322004-12-20 23:51:53 +00002039- StringIO.truncate() now correctly adjusts the size attribute.
2040 (Bug #951915).
2041
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002042- locale.py now uses an updated locale alias table (built using
2043 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2044 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002045 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002046
Raymond Hettinger3557f422004-12-07 12:02:02 +00002047- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2048
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002049- the pickle module no longer accepts the deprecated None option in the
2050 args tuple returned by __reduce__().
2051
Brett Cannon84667c02004-12-07 03:25:18 +00002052- optparse now optionally imports gettext. This allows its use in setup.py.
2053
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002054- the pickle module no longer uses the deprecated bin parameter.
2055
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002056- the shelve module no longer uses the deprecated binary parameter.
2057
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002058- the pstats module no longer uses the deprecated ignore() method.
2059
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002060- the filecmp module no longer uses the deprecated use_statcache argument.
2061
Raymond Hettinger664347b2004-12-04 21:21:53 +00002062- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2063 extended or overridden by subclasses. Formerly, the subclassed method would
2064 be ignored by the rest of the module. (Bug #1078905).
2065
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002066- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002067 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002068
Walter Dörwald36733692004-12-22 12:50:50 +00002069- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2070 once when a size argument is given. This prevents a buffer overflow in the
2071 tokenizer with very long source lines.
2072
Barry Warsaw538561e2006-01-01 21:48:54 +00002073- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2074 immediately after creating the object, without any intervening
2075 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002076
Skip Montanaro05885812005-01-16 20:48:27 +00002077- The reconvert.quote function can now emit triple-quoted strings. The
2078 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002079
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002080- ``UserString.MutableString`` now supports negative indices in
2081 ``__setitem__`` and ``__delitem__``
2082
Greg Ward40407942005-03-05 02:53:17 +00002083- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2084 correctly.
2085
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002086- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2087 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2088 character even if the user has passed a size parameter to get a proper
2089 line ending. Remove the special handling of a "\r\n" that has been split
2090 between two lines.
2091
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002092- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2093 about illegal code points. The codec now supports PEP 293 style error
2094 handlers.
2095
Walter Dörwald78a78b02005-09-01 12:04:29 +00002096- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002097 from the input stream, so that the output is a byte string in the correct
2098 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002099
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002100- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2101 considering it exactly like a '*'.
2102
Walter Dörwald007f8df2005-10-09 19:42:27 +00002103- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2104 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002105
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002106- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2107
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002108- Patch #1413711: Certain patterns of differences were making difflib
2109 touch the recursion limit.
2110
Walter Dörwald58917a62006-03-31 15:26:22 +00002111- Bug #947906: An object oriented interface has been added to the calendar
2112 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002113 called as a script (e.g. via ``python -mcalendar``). Localized month and
2114 weekday names can be ouput (even if an exotic encoding is used) using
2115 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002116
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002117Build
2118-----
2119
Neal Norwitz602d3392006-03-31 08:21:40 +00002120- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2121 by using -mieee gcc option.
2122
Martin v. Löwis86d66262006-02-17 08:40:11 +00002123- Patch #1432345: Make python compile on DragonFly.
2124
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002125- Build support for Win64-AMD64 was added.
2126
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002127- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2128
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002129- Patch #881820: look for openpty and forkpty also in libbsd.
2130
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002131- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2132 The zlib module is now builtin on Windows.
2133
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002134- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2135
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002136- Bug #1189330: configure did not correctly determine the necessary
2137 value of LINKCC if python was built with GCC 4.0.
2138
Trent Mick8321b422005-07-26 02:29:21 +00002139- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2140 vulnerability in zlib 1.2.1 and 1.2.2.
2141
Brett Cannon08cd5982005-04-24 22:26:38 +00002142- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2143 flags that change binary compatibility. Changes were also made to
2144 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002145 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002146
Bob Ippolitoed233462005-03-29 13:47:59 +00002147- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2148 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2149 no longer exists). This configure patch makes things right.
2150
Martin v. Löwise2713be2005-03-08 15:03:08 +00002151- Bug #1158607: Build with --disable-unicode again.
2152
Brett Cannon46d96232005-02-16 00:07:19 +00002153- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2154 defined. Discovered as a result of not being able to build on OS X.
2155
Brett Cannon516592f2004-12-07 00:42:59 +00002156- setup.py now uses the directories specified in LDFLAGS using the -L option
2157 and in CPPFLAGS using the -I option for adding library and include
2158 directories, respectively, for compiling extension modules against. This has
2159 led to the core being compiled using the values in CPPFLAGS. It also removes
2160 the need for the special-casing of both DarwinPorts and Fink for darwin since
2161 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2162 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2163 Fink, ``-I/opt/local/include`` for DarwinPorts).
2164
Brett Cannon43802422005-02-10 20:48:03 +00002165- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2166 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2167 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2168 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002170C API
2171-----
2172
Tim Petersc9d78aa2006-03-26 23:27:58 +00002173- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2174 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2175 is obtained via the ``PyObject_`` family, it must be released via the
2176 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2177 always been officially true, but when Python's small-object allocator was
2178 introduced, an attempt was made to cater to a few extension modules
2179 discovered at the time that obtained memory via ``PyObject_New`` but
2180 released it via ``PyMem_DEL``. It's years later, and if such code still
2181 exists it will fail now (probably with segfaults, but calling wrong
2182 low-level memory management functions can yield many symptoms).
2183
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002184- Added a C API for set and frozenset objects.
2185
Raymond Hettinger66517482004-12-03 11:45:13 +00002186- Removed PyRange_New().
2187
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002188- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2189 mapping argument now. This string is used as a mapping table. Byte values
2190 greater than the length of the string and 0xFFFE are treated as undefined
2191 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002198
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002199- Patch #1276356: New resource "urlfetch" is implemented. This enables
