12Core and builtins
13-----------------
14
Brett Cannonf6aa86e2006-09-20 18:43:13 +000015- Allow exception instances to be directly sliced again.
16
Brett Cannon9adeab72006-09-20 18:34:28 +000017- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
18 allows calling unicode() on exceptions classes directly to succeed.
19
Georg Brandlec6c2df2006-09-11 09:38:35 +000020- Make _PyGILState_NoteThreadState() static, it was not used anywhere
21 outside of pystate.c and should not be necessary.
22
Georg Brandl4e933132006-09-06 20:05:58 +000023- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
24 Also make sure that every exception class has __module__ set to
25 'exceptions'.
26
Georg Brandl98775df2006-09-06 06:09:31 +000027- Bug #1550983: emit better error messages for erroneous relative
28 imports (if not in package and if beyond toplevel package).
29
Tim Petersc10c9d02006-09-05 02:18:09 +000030- Overflow checking code in integer division ran afoul of new gcc
31 optimizations. Changed to be more standard-conforming.
32

Neal Norwitzd34e4272006-09-05 02:36:20 +000037- The return tuple from str.rpartition(sep) is (tail, sep, head) where
38 head is the original string if sep was not found.
39
Neal Norwitzdac090d2006-09-05 03:53:08 +000040- Bug #1520864: unpacking singleton tuples in list comprehensions and
41 generator expressions (x for x, in ... ) works again. Fixing this problem
42 required changing the .pyc magic number. This means that .pyc files
43 generated before 2.5c2 will be regenerated.
44
Neal Norwitzca460d92006-09-06 06:28:06 +000045- with and as are now keywords.

62 on systems with low clock resolution.
63

Guido van Rossumc69ac252006-08-10 18:09:25 +0000131What's New in Python 2.5 release candidate 1?
132=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000133
Anthony Baxterb4096662006-08-16 03:42:26 +0000134*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000135
136Core and builtins
137-----------------
138
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000139- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000140 compared equal or unequal to a string and a UnicodeDecodeError
141 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000142
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000143 Instead, the equal (==) and unequal (!=) comparison operators will
144 now issue a UnicodeWarning and interpret the two objects as
145 unequal. The UnicodeWarning can be filtered as desired using
146 the warning framework, e.g. silenced completely, turned into an
147 exception, logged, etc.
148
149 Note that compare operators other than equal and unequal will still
150 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000151
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000152- Fix segfault when doing string formatting on subclasses of long.
153
154- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
155 with new-style classes.
156
157- Fix bug related to __len__ functions returning negative values with
158 classic classes.
159
160- Patch #1538606, Fix __index__() clipping. There were some problems
161 discovered with the API and how integers that didn't fit into Py_ssize_t
162 were handled. This patch attempts to provide enough alternatives
163 to effectively use __index__.
164
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000165- Bug #1536021: __hash__ may now return long int; the final hash
166 value is obtained by invoking hash on the long int.
167
Thomas Hellerab1049c2006-08-08 17:37:00 +0000168- Bug #1536786: buffer comparison could emit a RuntimeWarning.
169
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000170- Bug #1535165: fixed a segfault in input() and raw_input() when
171 sys.stdin is closed.
172
Thomas Heller74d36f02006-08-04 18:17:40 +0000173- On Windows, the PyErr_Warn function is now exported from
174 the Python dll again.
175
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000176- Bug #1191458: tracing over for loops now produces a line event
177 on each iteration. Fixing this problem required changing the .pyc
178 magic number. This means that .pyc files generated before 2.5c1
179 will be regenerated.
180
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000181- Bug #1333982: string/number constants were inappropriately stored
182 in the byte code and co_consts even if they were not used, ie
183 immediately popped off the stack.
184
Georg Brandle9462c72006-08-04 18:03:37 +0000185- Fixed a reference-counting problem in property().
186
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000187
188Library
189-------
190
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000191- Fix a bug in the ``compiler`` package that caused invalid code to be
192 generated for generator expressions.
193
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000194- The distutils version has been changed to 2.5.0. The change to
195 keep it programmatically in sync with the Python version running
196 the code (introduced in 2.5b3) has been reverted. It will continue
197 to be maintained manually as static string literal.
198
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000199- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000200 and this cannot be converted to the required C type, an exception is
201 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000202 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000203
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000204- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000205 an exception.
206
Tim Petersc10c9d02006-09-05 02:18:09 +0000207- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000208 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000209 workarounds for clocks with low resolution, to stop the code yielding
210 duplicate UUIDs.
211
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000212- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
213 before raising SystemExit, allowing IDLE to honor quit() and exit().
214
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000215- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
216
Georg Brandl7a1af772006-08-14 21:55:28 +0000217- Patch #1536071: trace.py should now find the full module name of a
218 file correctly even on Windows.
219
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000220- logging's atexit hook now runs even if the rest of the module has
221 already been cleaned up.
222
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000223- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000224
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000225- Bug #1531405, format_exception no longer raises an exception if
226 str(exception) raised an exception.
227
Neil Schemenauer06ded092006-08-04 16:20:30 +0000228- Fix a bug in the ``compiler`` package that caused invalid code to be
229 generated for nested functions.
230
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000231

Georg Brandl3335a7a2006-08-14 21:42:55 +0000237- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
238 raises the correct exceptions.
239
Thomas Heller1ce433e2006-08-14 16:20:04 +0000240- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
241 '-no-stack-protector' compiler flag for OpenBSD has been removed.
242
Thomas Heller86720042006-08-14 11:17:48 +0000243- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
244 uses the _as_parameter_ attribute when objects are passed to foreign
245 function calls. The ctypes version number was changed to 1.0.1.
246
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000247- Bug #1530559, struct.pack raises TypeError where it used to convert.
248 Passing float arguments to struct.pack when integers are expected
249 now triggers a DeprecationWarning.

299Core and builtins
300-----------------
301
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000302- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000303 returned a long (see PEP 353).
304
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000305- Bug #1515471: string.replace() accepts character buffers again.
306
Neal Norwitz07aadb12006-07-30 06:55:48 +0000307- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
308 This provides the proper warning for struct.pack().
309 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
310
Neal Norwitz0d62a062006-07-30 06:53:31 +0000311- Patch #1531113: Fix augmented assignment with yield expressions.
312 Also fix a SystemError when trying to assign to yield expressions.
313
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000314- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
315 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
316 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
317 excessive filesystem operations during imports.
318
Tim Petersbc24eee2006-07-27 01:14:53 +0000319- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
320 operations on signed longs that are formally undefined by C.
321 Unfortunately, at least one compiler now cares about that, so complicated
322 the code to make that compiler happy again.
323
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000324- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
325
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000326- Patch #1232023: Stop including current directory in search
327 path on Windows.
328
Neal Norwitze1fdb322006-07-21 05:32:28 +0000329- Fix some potential crashes found with failmalloc.
330
Neal Norwitze7563102006-07-17 01:00:16 +0000331- Fix warnings reported by Klocwork's static analysis tool.
332
Neal Norwitz84be93b2006-07-16 01:50:38 +0000333- Bug #1512814, Fix incorrect lineno's when code within a function
334 had more than 255 blank lines.
335
Georg Brandl9dceedb2006-07-12 15:31:17 +0000336- Patch #1521179: Python now accepts the standard options ``--help`` and
337 ``--version`` as well as ``/?`` on Windows.
338
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000339- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000340 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000341 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000342
Tim Peters112aad32006-07-19 00:03:19 +0000343- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000344 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000345 new ``sys._current_frames()`` returns a dictionary with one entry,
346 mapping the faux "thread id" 0 to the current frame.
347
Ronald Oussoren3075e162006-07-25 20:28:55 +0000348- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

352-------
353
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000354- Correction of patch #1455898: In the mbcs decoder, set final=False
355 for stream decoder, but final=True for the decode function.
356
Georg Brandl07fec3a2006-08-01 18:49:24 +0000357- os.urandom no longer masks unrelated exceptions like SystemExit or
358 KeyboardInterrupt.
359
Tim Peters4643c2f2006-08-10 22:45:34 +0000360- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000361 shutil.copytree on Windows
362
Georg Brandle34ac7c2006-07-30 11:07:23 +0000363- Bug #1002398: The documentation for os.path.sameopenfile now correctly
364 refers to file descriptors, not file objects.
365
Tim Petersc10c9d02006-09-05 02:18:09 +0000366- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000367 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000368 #1513611, and probably others.
369
Georg Brandledd9b0d2006-07-29 09:33:26 +0000370- Bug #1441397: The compiler module now recognizes module and function
371 docstrings correctly as it did in Python 2.4.
372
Tim Peters6f681472006-07-27 23:44:37 +0000373- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
374 lost that tests are sorted by name before being run. This rarely
375 matters for well-written tests, but can create baffling symptoms if
376 side effects from one test to the next affect outcomes. ``DocTestFinder``
377 has been changed to sort the list of tests it returns.
378
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000379- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000380 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000381
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000382- Bug #978833: Really close underlying socket in _socketobject.close.
383
Georg Brandl8c036cc2006-08-20 13:15:39 +0000384- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
385 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000386
Georg Brandlcf0c1722006-07-26 07:23:32 +0000387- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
388 to recursive calls and call it with the failing package name.
389
Martin v. Löwis0b483032006-07-25 09:53:12 +0000390- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
391
Georg Brandlc13c34c2006-07-24 14:09:56 +0000392- Patch #1515343: Fix printing of deprecated string exceptions with a
393 value in the traceback module.
394
Greg Ward48fae7a2006-07-23 16:05:51 +0000395- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
396
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000397- Patch #1524429: Use repr() instead of backticks in Tkinter again.
398
Brett Cannoncaebe222006-07-18 04:41:36 +0000399- Bug #1520914: Change time.strftime() to accept a zero for any position in its
400 argument tuple. For arguments where zero is illegal, the value is forced to
401 the minimum value that is correct. This is to support an undocumented but
402 common way people used to fill in inconsequential information in the time
403 tuple pre-2.4.
404
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000405- Patch #1220874: Update the binhex module for Mach-O.
406
Barry Warsawb110bad2006-07-21 14:51:07 +0000407- The email package has improved RFC 2231 support, specifically for
408 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
409 (name*0=<blah>) parameter continuations. This may change the types of
410 values returned from email.message.Message.get_param() and friends.
411 Specifically in some cases where non-encoded continuations were used,
412 get_param() used to return a 3-tuple of (None, None, string) whereas now it
413 will just return the string (since non-encoded continuations don't have
414 charset and language parts).
415
416 Also, whereas % values were decoded in all parameter continuations, they are
417 now only decoded in encoded parameter parts.
418
Ronald Oussoren3075e162006-07-25 20:28:55 +0000419- Bug #1517990: IDLE keybindings on MacOS X now work correctly
420
421- Bug #1517996: IDLE now longer shows the default Tk menu when a
422 path browser, class browser or debugger is the frontmost window on MacOS X
423
Barry Warsaw00decd72006-07-27 23:43:15 +0000424- Patch #1520294: Support for getset and member descriptors in types.py,
425 inspect.py, and pydoc.py. Specifically, this allows for querying the type
426 of an object against these built-in types and more importantly, for getting
427 their docstrings printed in the interactive interpreter's help() function.

431-----------------
432
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000433- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
434 a socket operation on a socket with a timeout, the exception will be
435 caught correctly. Previously, the exception was not caught.
436
Thomas Heller1393d6a2006-07-28 21:43:20 +0000437- Patch #1529514: The _ctypes extension is now compiled on more
438 openbsd target platforms.
439
Tim Peters9cab5932006-07-28 00:30:00 +0000440- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
441 a memory leak, affecting pickles and deep copies.
442
Tim Petersbc24eee2006-07-27 01:14:53 +0000443- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000444 Paul Eggert.
445
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000446- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
447
Thomas Hellerce049a02006-07-14 17:51:14 +0000448- Patch #1521817: Index range checking on ctypes arrays containing
449 exactly one element enabled again. This allows iterating over these
450 arrays, without the need to check the array size before.
451
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000452- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000453 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000454 /dev/null in certain cases; this is now fixed.
455
Thomas Heller47d7a062006-07-12 08:43:47 +0000456- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
457 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000458
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000459- Because of a misspelled preprocessor symbol, ctypes was always
460 compiled without thread support; this is now fixed.
461
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000462- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
463 methods now allow their database parameter to be None as the
464 sleepycat API allows.
465
Matt Flemingec926502006-07-28 11:27:27 +0000466- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
467 bluetooth API compared with Linux and FreeBSD.
468
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000469Tests
470-----
471
472- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
473 how long the test file should take to play. Now accepts taking 2.93 secs
474 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
475
Georg Brandl4793aa32006-07-28 18:31:39 +0000476- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
477 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
478 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000485Mac
486---
487
488- PythonLauncher now works correctly when the path to the script contains
489 characters that are treated specially by the shell (such as quotes).
490
491- Bug #1527397: PythonLauncher now launches scripts with the working directory
492 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000493 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000494 expect.

502Core and builtins
503-----------------
504
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000505- Bug #1441486: The literal representation of -(sys.maxint - 1)
506 again evaluates to a int object, not a long.
507
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000508- Bug #1501934: The scope of global variables that are locally assigned
509 using augmented assignment is now correctly determined.
510
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000511- Bug #927248: Recursive method-wrapper objects can now safely
512 be released.
513
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000514- Bug #1417699: Reject locale-specific decimal point in float()
515 and atof().
516
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000517- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
518 omit a default "error" argument for NULL pointer. This allows
519 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000520
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000521- Bug #1519018: 'as' is now validated properly in import statements.
522
Neal Norwitz28746ab2006-07-09 22:14:42 +0000523- On 64 bit systems, int literals that use less than 64 bits are
524 now ints rather than longs.
525
Neal Norwitzed657552006-07-10 00:04:44 +0000526- Bug #1512814, Fix incorrect lineno's when code at module scope
527 started after line 256.
528
Tim Peters32a83612006-07-10 21:08:24 +0000529- New function ``sys._current_frames()`` returns a dict mapping thread
530 id to topmost thread stack frame. This is for expert use, and is
531 especially useful for debugging application deadlocks. The functionality
532 was previously available in Fazal Majid's ``threadframe`` extension
533 module, but it wasn't possible to do this in a wholly threadsafe way from
534 an extension.

543
Tim Peters32a83612006-07-10 21:08:24 +0000544- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000545 environment variable to be set in order to the SDK environment
546 for finding the compiler, include files, etc.

551
Thomas Woutersadd19112006-07-05 11:03:49 +0000552- string.Template() now correctly handles tuple-values. Previously,
553 multi-value tuples would raise an exception and single-value tuples would
554 be treated as the value they contain, instead.
555
Martin v. Löwisede77f52006-07-03 13:01:35 +0000556- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
557 even if some data are received.
558
Martin v. Löwis45482392006-07-03 12:28:58 +0000559- Bug #1267547: Put proper recursive setup.py call into the

563 degrees and radians.
564
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000565- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000566 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000567
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000568- Bug #1514703: Only setup canvas window in turtle when the canvas
569 is created.
570
Martin v. Löwis7596e832006-07-01 15:33:37 +0000571- Bug #1513223: .close() of a _socketobj now releases the underlying
572 socket again, which then gets closed as it becomes unreferenced.
573
Fred Drake10497c82006-06-29 02:57:48 +0000574- Bug #1504333: Make sgmllib support angle brackets in quoted
575 attribute values.
576
577- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
578 sgmllib ('[' and ']' were not accepted).
579
Georg Brandl1be63af2006-06-28 20:23:25 +0000580- Fix a bug in the turtle module's end_fill function.
581
Brett Cannon53ab5b72006-06-22 16:49:14 +0000582- Bug #1510580: The 'warnings' module improperly required that a Warning
583 category be either a types.ClassType and a subclass of Warning. The proper
584 check is just that it is a subclass with Warning as the documentation states.
585
Georg Brandlad29e632006-06-21 17:45:17 +0000586- The compiler module now correctly compiles the new try-except-finally
587 statement (bug #1509132).
588
Neal Norwitz60373cd2006-06-22 06:30:50 +0000589- The wsgiref package is now installed properly on Unix.
590
Vinay Sajip28e57612006-07-01 10:45:20 +0000591- A bug was fixed in logging.config.fileConfig() which caused a crash on
592 shutdown when fileConfig() was called multiple times.
593
Gerhard Häring762fbd32006-07-02 17:48:30 +0000594- The sqlite3 module did cut off data from the SQLite database at the first
595 null character before sending it to a custom converter. This has been fixed
596 now.

Tim Peters112aad32006-07-19 00:03:19 +0000601- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
602 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
603 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000604
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000605- Assigning None to pointer type fields in ctypes structures possible
606 overwrote the wrong fields, this is fixed now.
607
608- Fixed a segfault in _ctypes when ctypes.wintypes were imported
609 on non-Windows platforms.
610
611- Bug #1518190: The ctypes.c_void_p constructor now accepts any
612 integer or long, without range checking.
613
614- Patch #1517790: It is now possible to use custom objects in the ctypes
615 foreign function argtypes sequence as long as they provide a from_param
616 method, no longer is it required that the object is a ctypes type.
617
618- The '_ctypes' extension module now works when Python is configured
619 with the --without-threads option.
620
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000621- Bug #1513646: os.access on Windows now correctly determines write
622 access, again.
623
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000624- Bug #1512695: cPickle.loads could crash if it was interrupted with
625 a KeyboardInterrupt.
626
Neal Norwitza12aa882006-07-06 06:45:08 +0000627- Bug #1296433: parsing XML with a non-default encoding and
628 a CharacterDataHandler could crash the interpreter in pyexpat.
629
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000630- Patch #1516912: improve Modules support for OpenVMS.

633-----
634
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000635- Automate Windows build process for the Win64 SSL module.
636
Tim Peters32a83612006-07-10 21:08:24 +0000637- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000638 Previously, the slight difference could cause compilation errors of the
639 'zlib' module on systems with more than one version of zlib.
640
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000641- The MSI compileall step was fixed to also support a TARGETDIR
642 with spaces in it.
643
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000644- Bug #1517388: sqlite3.dll is now installed on Windows independent
645 of Tcl/Tk.
646
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000647- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000648 trying to be installed even though it's empty.

651-----
652
653- Call os.waitpid() at the end of tests that spawn child processes in order
654 to minimize resources (zombies).

Nick Coghlan2d792252006-07-06 13:47:18 +0000659- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
660 documentation for the warnings module.
661
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000662- Patch #1509163: MS Toolkit Compiler no longer available.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000669
Anthony Baxterd1136802006-06-19 12:04:15 +0000670*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000671
672Core and builtins
673-----------------
674
Georg Brandla56b9152006-06-19 06:35:54 +0000675- Patch #1507676: Error messages returned by invalid abstract object operations
676 (such as iterating over an integer) have been improved and now include the
677 type of the offending object to help with debugging.
678
Brett Cannonea3912b2006-06-13 21:46:41 +0000679- Bug #992017: A classic class that defined a __coerce__() method that returned
680 its arguments swapped would infinitely recurse and segfault the interpreter.
681
Neal Norwitz909eb122006-06-12 02:13:21 +0000682- Fix the socket tests so they can be run concurrently.
683
Neal Norwitzb9845e72006-06-12 02:11:18 +0000684- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000685 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000686
Brett Cannon22565aa2006-06-09 22:31:23 +0000687- Bug #532646: object.__call__() will continue looking for the __call__
688 attribute on objects until one without one is found. This leads to recursion
689 when you take a class and set its __call__ attribute to an instance of the
690 class. Originally fixed for classic classes, but this fix is for new-style.
691 Removes the infinite_rec_3 crasher.
692
Georg Brandl24250812006-06-09 18:45:48 +0000693- The string and unicode methods startswith() and endswith() now accept
694 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
695
Brett Cannonde3b0522006-06-08 17:00:45 +0000696- Buffer objects, at the C level, never used the char buffer
697 implementation even when the char buffer for the wrapped object was
698 explicitly requested (originally returned the read or write buffer).
699 Now a TypeError is raised if the char buffer is not present but is
700 requested.
701
Georg Brandlddbaa662006-06-04 21:56:52 +0000702- Patch #1346214: Statements like "if 0: suite" are now again optimized
703 away like they were in Python 2.4.
704
Georg Brandlb7c8f542006-05-27 12:30:25 +0000705- Builtin exceptions are now full-blown new-style classes instead of
706 instances pretending to be classes, which speeds up exception handling
707 by about 80% in comparison to 2.5a2.
708
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000709- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
710 Unicode 4.1.
711
Georg Brandlf4ef1162006-05-26 18:03:31 +0000712- Patch #921466: sys.path_importer_cache is now used to cache valid and
713 invalid file paths for the built-in import machinery which leads to
714 fewer open calls on startup.
715
Tim Peters696cf432006-05-24 21:10:40 +0000716- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
717 of-2 bases. The largest speedup is for inputs with about 1000 decimal
718 digits. Conversion from non-power-of-2 bases remains quadratic-time in
719 the number of input digits (it was and remains linear-time for bases
720 2, 4, 8, 16 and 32).
721
Tim Petersb713ec22006-05-23 18:45:30 +0000722- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
723 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
724 an integer close to ``sys.maxint``. This was repaired by patch
725 #1335972, which also gives a nice speedup.
726
Richard Jonescebbefc2006-05-23 18:28:17 +0000727- Patch #1337051: reduced size of frame objects.
728
729- PyErr_NewException now accepts a tuple of base classes as its
730 "base" parameter.
731
Richard Jones7c88dcc2006-05-23 10:37:38 +0000732- Patch #876206: function call speedup by retaining allocated frame
733 objects.
734
Georg Brandl7b90e162006-05-18 07:01:27 +0000735- Bug #1462152: file() now checks more thoroughly for invalid mode
736 strings and removes a possible "U" before passing the mode to the
737 C library function.
738
Neal Norwitz1004a532006-05-15 07:17:23 +0000739- Patch #1488312, Fix memory alignment problem on SPARC in unicode
740
Neal Norwitz373f0a72006-05-15 07:04:36 +0000741- Bug #1487966: Fix SystemError with conditional expression in assignment
742
Martin v. Löwis879768d2006-05-11 13:28:43 +0000743- WindowsError now has two error code attributes: errno, which carries
744 the error values from errno.h, and winerror, which carries the error
745 values from winerror.h. Previous versions put the winerror.h values
746 (from GetLastError()) into the errno attribute.
747
Martin v. Löwis77736712006-05-04 05:51:03 +0000748- Patch #1475845: Raise IndentationError for unexpected indent.
749
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000750- Patch #1479181: split open() and file() from being aliases for each other.
751
Tim Peters44bd9862006-06-01 13:49:23 +0000752- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
753 methods were always silently ignored by dictionaries when comparing keys.
754 They are now passed through (except when using the C API function
755 ``PyDict_GetItem()``, whose semantics did not change).
756
757- Bug #1456209: In some obscure cases it was possible for a class with a
758 custom ``__eq__()`` method to confuse dict internals when class instances
759 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
760 No, you don't have any code that did this ;-)

766
767- Patch #1462338: Upgrade pyexpat to expat 2.0.0
768
Brett Cannon6ee7d012006-06-08 16:23:04 +0000769- Change binascii.hexlify to accept a read-only buffer instead of only a char
770 buffer and actually follow its documentation.
771
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000772- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
773
Nick Coghlanc649ec52006-05-29 12:43:05 +0000774- Patch #1478788 (modified version): The functional extension module has
775 been renamed to _functools and a functools Python wrapper module added.
776 This provides a home for additional function related utilities that are
777 not specifically about functional programming. See PEP 309.
778
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000779- Patch #1493701: performance enhancements for struct module.
780
Georg Brandl378d5922006-05-17 14:26:50 +0000781- Patch #1490224: time.altzone is now set correctly on Cygwin.
782
Georg Brandl8d3342b2006-05-16 07:38:27 +0000783- Patch #1435422: zlib's compress and decompress objects now have a
784 copy() method.
785
Andrew MacIntyre92913322006-06-13 15:04:24 +0000786- Patch #1454481: thread stack size is now tunable at runtime for thread
787 enabled builds on Windows and systems with Posix threads support.
788
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000789- On Win32, os.listdir now supports arbitrarily-long Unicode path names
790 (up to the system limit of 32K characters).
791
792- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
793 As a result, these functions now raise WindowsError instead of OSError.
794
Tim Peters7a822da2006-05-25 21:50:17 +0000795- ``time.clock()`` on Win64 should use the high-performance Windows
796 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
797 Windows platforms).
798
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000799- Calling Tk_Init twice is refused if the first call failed as that
800 may deadlock.
801
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000802- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
803 accept it without potentially using an uninitialized pointer.
804
805- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
806 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
807 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000808
Gregory P. Smith372b5832006-06-05 18:48:21 +0000809- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000810 [pybsddb project SF patch number 1466734]
811
Gregory P. Smith372b5832006-06-05 18:48:21 +0000812- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
813 parameter is supplied. [SF pybsddb bug #1477863]
814
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000815- bsddb: the __len__ method of a DB object has been fixed to return correct
816 results. It could previously incorrectly return 0 in some cases.
817 Fixes SF bug 1493322 (pybsddb bug 1184012).
818
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000819- bsddb: the bsddb.dbtables Modify method now raises the proper error and
820 aborts the db transaction safely when a modifier callback fails.
821 Fixes SF python patch/bug #1408584.
822
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000823- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000824 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000825 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
826 database calls that would previously deadlock. [SF python bug #775414]
827
Vinay Sajip28e57612006-07-01 10:45:20 +0000828- Patch #1446489: add support for the ZIP64 extensions to zipfile.

834-------
835
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000836- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
837 functions.
838
Martin v. Löwis3798da02006-06-17 18:44:27 +0000839- Patch #812986: Update turtle output even if not tracing.
840
Vinay Sajip28e57612006-07-01 10:45:20 +0000841- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000842 Tkinter.BaseWidget.
843
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000844- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
845
Martin v. Löwis337487e2006-06-17 09:15:14 +0000846- Patch #763580: Add name and value arguments to Tkinter variable
847 classes.
848
Georg Brandl83cc0d02006-06-14 08:50:03 +0000849- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
850 mime.types file for determining MIME types.
851
Georg Brandl2605ca82006-06-14 06:08:31 +0000852- Bug #1339007: Shelf objects now don't raise an exception in their
853 __del__ method when initialization failed.
854
Martin v. Löwisd8251432006-06-14 05:21:04 +0000855- Patch #1455898: The MBCS codec now supports the incremental mode for
856 double-byte encodings.
857
Tim Peters43898b42006-06-14 04:09:25 +0000858- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
859 guarantee that adjacent triples in the return list always describe
860 non-adjacent blocks. Previously, a pair of matching blocks could end
861 up being described by multiple adjacent triples that formed a partition
862 of the matching pair.
863
Greg Ward0e0c9f42006-06-11 16:24:11 +0000864- Bug #1498146: fix optparse to handle Unicode strings in option help,
865 description, and epilog.
866
Greg Wardd1c797e2006-06-11 14:42:41 +0000867- Bug #1366250: minor optparse documentation error.
868
Greg Ward7f547402006-06-11 00:40:49 +0000869- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
870 clarify docs.
871
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000872- The wsgiref package has been added to the standard library.
873
Nick Coghlan676725d2006-06-08 13:54:49 +0000874- The functions update_wrapper() and wraps() have been added to the functools
875 module. These make it easier to copy relevant metadata from the original
876 function when writing wrapper functions.
877
Tim Petersd6a9eef2006-06-05 01:48:21 +0000878- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
879 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000880
Martin v. Löwis3f767792006-06-04 19:36:28 +0000881- Patch #1359618: Speed up charmap encoder by using a trie structure
882 for lookup.
883
Tim Petersd609b1a2006-06-02 23:22:51 +0000884- The functions in the ``pprint`` module now sort dictionaries by key
885 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
886 if and only if its display required more than one line, although that
887 wasn't documented. The new behavior increases predictability; e.g.,
888 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
889
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000890- Patch #1497027: try HTTP digest auth before basic auth in urllib2
891 (thanks for J. J. Lee).
892
Georg Brandl2b330372006-05-28 20:23:12 +0000893- Patch #1496206: improve urllib2 handling of passwords with respect to
894 default HTTP and HTTPS ports.
895
George Yoshidaf3c65de2006-05-28 16:39:09 +0000896- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
897
Bob Ippolito7298f272006-05-23 18:43:47 +0000898- Patch #1281707: speed up gzip.readline.
899
Georg Brandlb89316f2006-05-17 15:51:16 +0000900- Patch #1180296: Two new functions were added to the locale module:
901 format_string() to get the effect of "format % items" but locale-aware,
902 and currency() to format a monetary number with currency sign.
903
Georg Brandle3a25832006-05-17 14:56:04 +0000904- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
905 and several features added, such as speed and geometry control.
906
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000907- Patch #1488881: add support for external file objects in bz2 compressed
908 tarfiles.
909
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000910- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
911 stdout arguments, making it possible to redirect input and output
912 for remote debugging.
913
914- Patch #1484695: Update the tarfile module to version 0.8. This fixes
915 a couple of issues, notably handling of long file names using the
916 GNU LONGNAME extension.
917
918- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
919 new flag when ``name`` is already the name of an option flag.
920
921- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
922 package.
923
924- Patch #1472854: make the rlcompleter.Completer class usable on non-
925 UNIX platforms.
926
927- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
928
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000929- Bug #1472827: correctly escape newlines and tabs in attribute values in
930 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000960What's New in Python 2.5 alpha 2?
961=================================
962
963*Release date: 27-APR-2006*
964
965Core and builtins
966-----------------
967
Thomas Heller1b046642006-04-18 18:51:06 +0000968- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
969 by converting these apis from macros into exported functions again:
970
971 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
972 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
973 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
974 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
975 PyRun_String Py_CompileString
976
Martin v. Löwis45294a92006-04-18 06:24:08 +0000977- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
978
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000979- All uses of PyStructSequence_InitType have been changed to initialize
980 the type objects only once, even if the interpreter is initialized
981 multiple times.
982
Neal Norwitz61546162006-04-14 05:20:28 +0000983- Bug #1454485, array.array('u') could crash the interpreter. This was
984 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
985 to unicode when it didn't make sense. 'u#' now requires a unicode string.
986
987- Py_UNICODE is unsigned. It was always documented as unsigned, but
988 due to a bug had a signed value in previous versions.
989
Tim Peters3a5e8b12006-04-11 01:44:07 +0000990- Patch #837242: ``id()`` of any Python object always gives a positive
991 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
992 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000993 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000994 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000995
Tim Peters3a5e8b12006-04-11 01:44:07 +0000996 def __hash__(self):
997 return id(self) # WRONG
998
999 because a hash result must be a (short) Python int but it was always
1000 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001001 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001002 was always usable as a hash value before this patch. That's no longer
1003 necessarily so.
1004
1005- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001006 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001007 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001008 #1454844)
1009
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001010- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1011 involving generators that have paused outside of any ``try`` or ``with``
1012 blocks. (In 2.5a1, a paused generator that was part of a reference
1013 cycle could not be garbage collected, regardless of whether it was
1014 paused in a ``try`` or ``with`` block.)

1018
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001019- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1020 is a macro.
1021
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001022- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1023 fails with an error condition.
1024
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001025- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1026
1027- Bug #1117761: bsddb.*open() no longer raises an exception when using
1028 the cachesize parameter.
1029
1030- Bug #1149413: bsddb.*open() no longer raises an exception when using
1031 a temporary db (file=None) with the 'n' flag to truncate on open.
1032
1033- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1034 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001035
Armin Rigoa9017c32006-04-19 11:50:27 +00001036- Patch #1062014: AF_UNIX sockets under Linux have a special
1037 abstract namespace that is now fully supported.
1038
Anthony Baxter51bcb682006-04-05 14:51:42 +00001039Library
1040-------
1041
Peter Astrand7d1d4362006-07-14 14:04:45 +00001042- Bug #1223937: subprocess.CalledProcessError reports the exit status
1043 of the process using the returncode attribute, instead of
1044 abusing errno.
1045
Tim Peters711bf302006-04-25 03:31:36 +00001046- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1047 a doctest to be skipped (the code is not run, and the expected output
1048 or exception is ignored).
1049
Nick Coghlanda2268f2006-04-24 04:37:15 +00001050- Fixed contextlib.nested to cope with exceptions being raised and
1051 caught inside exit handlers.
1052
Greg Wardab05edc2006-04-23 03:47:58 +00001053- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1054 hex, octal, or binary; add ``append_const`` action; keep going if
1055 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1056 added ``epilog`` for better help generation).
1057
Tim Peters21fbd572006-04-21 21:18:10 +00001058- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1059 called from a thread spawned as a side effect of importing a module.
1060
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001061- The pydoc module now supports documenting packages contained in
1062 .zip or .egg files.
1063
1064- The pkgutil module now has several new utility functions, such
1065 as ``walk_packages()`` to support working with packages that are either
1066 in the filesystem or zip files.
1067
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001068- The mailbox module can now modify and delete messages from
1069 mailboxes, in addition to simply reading them. Thanks to Gregory
1070 K. Johnson for writing the code, and to the 2005 Google Summer of
1071 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001072
Tim Petersc7605f22006-04-17 21:12:33 +00001073- The ``__del__`` method of class ``local`` in module ``_threading_local``
1074 returned before accomplishing any of its intended cleanup.
1075
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001076- Patch #790710: Add breakpoint command lists in pdb.
1077
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001078- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1079
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001080- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1081
Anthony Baxtere29002c2006-04-12 12:07:31 +00001082- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1083 Windows. Bug #1469163.
1084
Phillip J. Eby47032112006-04-11 01:07:43 +00001085- The warnings, linecache, inspect, traceback, site, and doctest modules
1086 were updated to work correctly with modules imported from zipfiles or
1087 via other PEP 302 __loader__ objects.
1088
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001089- Patch #1467770: Reduce usage of subprocess._active to processes which
1090 the application hasn't waited on.
1091
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001092- Patch #1462222: Fix Tix.Grid.
1093
Neal Norwitza31bf182006-04-09 03:35:43 +00001094- Fix exception when doing glob.glob('anything*/')
1095
Skip Montanaro262fb922006-04-21 02:31:07 +00001096- The pstats.Stats class accepts an optional stream keyword argument to
1097 direct output to an alternate file-like object.
1098

1100-----
1101
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001102- The Makefile now has a reindent target, which runs reindent.py on
1103 the library.
1104
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001105- Patch #1470875: Building Python with MS Free Compiler
1106
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001107- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001108
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001109- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1110 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001111 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001112 CXX from --with-cxx-main, see description in README.
1113
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001114- Patch #1429775: Link extension modules with the shared libpython.
1115
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001116- Fixed a libffi build problem on MIPS systems.
1117
Tim Peters8931ff12006-05-13 23:28:20 +00001118- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1119 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1120 and "%zu" for unsigned integers of type ``size_t``.
1121
Anthony Baxter51bcb682006-04-05 14:51:42 +00001122Tests
1123-----
1124
Nick Coghlanda2268f2006-04-24 04:37:15 +00001125- test_contextlib now checks contextlib.nested can cope with exceptions
1126 being raised and caught inside exit handlers.
1127
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001128- test_cmd_line now checks operation of the -m and -c command switches
1129
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001130- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1131 it separately and by hand. It also wasn't cleaning up its changes to
1132 the current Decimal context.
1133
Thomas Woutersabd08882006-04-26 15:53:30 +00001134- regrtest.py now has a -M option to run tests that test the new limits of
1135 containers, on 64-bit architectures. Running these tests is only sensible
1136 on 64-bit machines with more than two gigabytes of memory. The argument
1137 passed is the maximum amount of memory for the tests to use.

1146-------------
1147
Tim Petersb06d28c2006-05-12 01:57:59 +00001148- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1149
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001150- PEP 343: Added Context Types section to the library reference
1151 and attempted to bring other PEP 343 related documentation into
1152 line with the implementation and/or python-dev discussions.
1153
Tim Peters8dc73d22006-04-24 02:03:16 +00001154- Bug #1337990: clarified that ``doctest`` does not support examples
1155 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001158What's New in Python 2.5 alpha 1?
1159=================================
1160
Anthony Baxterebed3f62006-04-03 15:03:44 +00001161*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001162
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001163Core and builtins
1164-----------------
1165
Nick Coghlan43832302006-04-23 17:04:07 +00001166- PEP 338: -m command line switch now delegates to runpy.run_module
1167 allowing it to support modules in packages and zipfiles
1168
Martin v. Löwisc661b882006-04-20 04:54:23 +00001169- On Windows, .DLL is not an accepted file name extension for
1170 extension modules anymore; extensions are only found if they
1171 end in .PYD.
1172
Martin v. Löwisea62d252006-04-03 10:56:49 +00001173- Bug #1421664: sys.stderr.encoding is now set to the same value as
1174 sys.stdout.encoding.
1175
Neal Norwitz92e212f2006-04-03 04:48:37 +00001176- __import__ accepts keyword arguments.
1177
Georg Brandlccadf842006-03-31 18:54:53 +00001178- Patch #1460496: round() now accepts keyword arguments.
1179
Anthony Baxter262c00a2006-03-30 10:53:17 +00001180- Fixed bug #1459029 - unicode reprs were double-escaped.
1181
Hye-Shik Changd478f342006-03-23 12:32:36 +00001182- Patch #1396919: The system scope threads are reenabled on FreeBSD
1183 5.4 and later versions.
1184
Neal Norwitze98ccf62006-03-23 05:39:47 +00001185- Bug #1115379: Compiling a Unicode string with an encoding declaration
1186 now gives a SyntaxError.
1187
Georg Brandlabd1ff82006-03-18 07:59:59 +00001188- Previously, Python code had no easy way to access the contents of a
1189 cell object. Now, a ``cell_contents`` attribute has been added
1190 (closes patch #1170323).
1191
Tim Peterscf79aac2006-03-16 01:14:46 +00001192- Patch #1123430: Python's small-object allocator now returns an arena to
1193 the system ``free()`` when all memory within an arena becomes unused
1194 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1195 freed. Some applications will see a drop in virtual memory size now,
1196 especially long-running applications that, from time to time, temporarily
1197 use a large number of small objects. Note that when Python returns an
1198 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001199 platform C library will in turn return that memory to the operating system.
1200 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001201 appears to be effective at least on Microsoft C and gcc-based systems.
1202 Thanks to Evan Jones for hard work and patience.
1203
Georg Brandl533ff6f2006-03-08 18:09:27 +00001204- Patch #1434038: property() now uses the getter's docstring if there is
1205 no "doc" argument given. This makes it possible to legitimately use
1206 property() as a decorator to produce a read-only property.
1207
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001208- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1209 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1210 of requiring an int or long in slicing and a few other contexts, enabling
1211 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1212
Neal Norwitz995acdf2006-03-07 05:01:00 +00001213- Fixed various bugs reported by Coverity's Prevent tool.
1214
Brett Cannonbf364092006-03-01 04:25:17 +00001215- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1216 new exception base class, BaseException, which has a new message attribute.
1217 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1218 Raising a string exception now raises a DeprecationWarning.
1219
Thomas Woutersfb609f42006-02-28 16:37:25 +00001220- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1221 explicitly relative, using 'from .module import name' to mean 'from the same
1222 package as this module is in. Imports without dots still default to the
1223 old relative-then-absolute, unless 'from __future__ import
1224 absolute_import' is used.
1225
Brett Cannona7446e32006-02-27 23:39:10 +00001226- Properly check if 'warnings' raises an exception (usually when a filter set
1227 to "error" is triggered) when raising a warning for raising string
1228 exceptions.
1229
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001230- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001231 The name was removed from Include/code.h.
1232
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001233- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001234
Guido van Rossum1968ad32006-02-25 22:38:04 +00001235- Patch 1433928:
1236 - The copy module now "copies" function objects (as atomic objects).
1237 - dict.__getitem__ now looks for a __missing__ hook before raising
1238 KeyError.
1239
Tim Peters84ef21c2006-02-28 20:39:06 +00001240- PEP 343: with statement implemented. Needs ``from __future__ import
1241 with_statement``. Use of 'with' as a variable will generate a warning.
1242 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001243 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001244 The following objects have __context__ methods:
1245 - The built-in file type.
1246 - The thread.LockType type.
1247 - The following types defined by the threading module:
1248 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1249 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001250
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001251- Fix the encodings package codec search function to only search
1252 inside its own package. Fixes problem reported in patch #1433198.
1253
1254 Note: Codec packages should implement and register their own
1255 codec search function. PEP 100 has the details.
1256
Tim Peters9ea89d22006-06-04 03:26:02 +00001257- PEP 353: Using ``Py_ssize_t`` as the index type.
1258
1259- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1260 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1261 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1262 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1263 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001264
Neal Norwitzfc76d632006-01-10 06:03:13 +00001265- Patch #1400181, fix unicode string formatting to not use the locale.
1266 This is how string objects work. u'%f' could use , instead of .
1267 for the decimal point. Now both strings and unicode always use periods.
1268
Neal Norwitz671b9e32006-01-09 07:07:12 +00001269- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1270 configure would break checking curses.h.
1271
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001272- Bug #959576: The pwd module is now builtin. This allows Python to be
1273 built on UNIX platforms without $HOME set.
1274
Neal Norwitzc10978f2005-12-19 06:07:16 +00001275- Bug #1072182, fix some potential problems if characters are signed.
1276
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001277- Bug #889500, fix line number on SyntaxWarning for global declarations.
1278
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001279- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1280
Neal Norwitze7214a12005-12-18 05:03:17 +00001281- Support for converting hex strings to floats no longer works.
1282 This was not portable. float('0x3') now raises a ValueError.
1283
Barry Warsaw2a38a862005-12-18 01:27:35 +00001284- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001285 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001286 is now displayed in interactive prompt banner.
1287
Georg Brandlfa166682005-12-17 21:45:17 +00001288- Implementation of PEP 341 - Unification of try/except and try/finally.
1289 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001290 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001291
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001292- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1293 now encodes backslash correctly.
1294
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001295- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1296
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001297- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001298 and long longs.
1299
Neal Norwitz67715f02005-11-09 06:59:35 +00001300- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001301 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001302 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001303
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001304- Replaced most Unicode charmap codecs with new ones using the
1305 new Unicode translate string feature in the builtin charmap
1306 codec; the codecs were created from the mapping tables available
1307 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1308 encodings now include a mapping for the Apple logo)
1309
Tim Peterse3547fd2005-12-16 23:13:57 +00001310- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001311
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001312- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001313
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001314- A new AST parser implementation was completed. The abstract
1315 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001316 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001317
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001318- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001319 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1320
Neal Norwitz708e51a2005-10-03 04:48:15 +00001321- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1322
Neal Norwitz11bd1192005-10-03 00:54:56 +00001323- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1324 Provide a warning when a directory is passed on the command line.
1325
Neal Norwitz40d37812005-10-02 01:48:49 +00001326- Fix segfault with invalid coding.
1327
1328- SF bug #772896: unknown encoding results in MemoryError.
1329
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001330- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001331 supported a __len__() method which evaluated to False when the iterator
1332 was empty.
1333
Guido van Rossum630db602005-09-20 18:49:54 +00001334- On 64-bit platforms, when __len__() returns a value that cannot be
1335 represented as a C int, raise OverflowError.
1336
Skip Montanarof8948ca2005-09-19 03:54:46 +00001337- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001338 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001339
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001340- SF bug #893549: parsing keyword arguments was broken with a few format
1341 codes.
1342
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001343- Changes donated by Elemental Security to make it work on AIX 5.3
1344 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1345 bug #105470: test_pwd fails on 64bit system (Opteron).
1346
Guido van Rossum539c6622005-09-14 17:49:54 +00001347- Changes donated by Elemental Security to make it work on HP-UX 11 on
1348 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1349
Georg Brandl4550b8d2005-08-26 06:43:52 +00001350- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001351 (fixes bug #1119418).
1352
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001353- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1354
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001355- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1356 exceptions that cause a function to exit.
1357
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001358- The implementation of set() and frozenset() was revised to use its
1359 own internal data structure. Memory consumption is reduced by 1/3
1360 and there are modest speed-ups as well. The API is unchanged.
1361
Tim Petersde7990b2005-07-17 23:45:23 +00001362- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1363
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001364- SF bug #1229429: PyObject_CallMethod failed to decrement some
1365 reference counts in some error exit cases.
1366
Tim Petersecc6e6a2005-07-10 22:30:55 +00001367- SF bug #1185883: Python's small-object memory allocator took over
1368 a block managed by the platform C library whenever a realloc specified
1369 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001370 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001371 portable way to copy data from the C-managed block into Python's
1372 small-object space without risking a memory fault. Python's small-object
1373 realloc now leaves such blocks under the control of the platform C
1374 realloc.
1375
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001376- SF bug #1232517: An overflow error was not detected properly when
1377 attempting to convert a large float to an int in os.utime().
1378
Raymond Hettinger3296e692005-06-29 23:29:56 +00001379- SF bug #1224347: hex longs now print with lowercase letters just
1380 like their int counterparts.
1381
Michael W. Hudson188d4362005-06-20 16:52:57 +00001382- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1383 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1384 interpreter states; back out that fix and do a better job (see
1385 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1386 for a longer write-up of the problem).
1387
Michael W. Hudsondf888462005-06-03 14:41:55 +00001388- SF patch #1180995: marshal now uses a binary format by default when
1389 serializing floats.
1390
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001391- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1392 the routines that promise to produce IEEE 754 binary representations
1393 of floats now simply copy bytes around.
1394
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001395- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1396 278.
1397
Brett Cannonc3647ac2005-04-26 03:45:26 +00001398- patch #1109424: int, long, float, complex, and unicode now check for the
1399 proper magic slot for type conversions when subclassed. Previously the
1400 magic slot was ignored during conversion. Semantics now match the way
1401 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001402 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001403 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001404 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001405
Barry Warsawc8d907c2005-04-19 23:43:40 +00001406- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1407 NULL, now raise an AttributeError when attempting to set or delete the
1408 attribute. Previously a TypeError was raised, but this was inconsistent
1409 with the equivalent pure-Python implementation.
1410
Michael W. Hudson774479c2005-04-18 08:46:17 +00001411- It is now safe to call PyGILState_Release() before
1412 PyEval_InitThreads() (note that if there is reason to believe there
1413 are multiple threads around you still must call PyEval_InitThreads()
1414 before using the Python API; this fix is for extension modules that
1415 have no way of knowing if Python is multi-threaded yet).
1416
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001417- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1418 disabled caused a crash.
1419
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001420- Bug #1165306: instancemethod_new allowed the creation of a method
1421 with im_class == im_self == NULL, which caused a crash when called.
1422
Tim Petersecc6e6a2005-07-10 22:30:55 +00001423- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001424 fixes the crash seen in bug #1165761
1425
Raymond Hettinger96229b12005-03-11 06:49:40 +00001426- Added two new builtins, any() and all().
1427
Brett Cannon409d8f22005-03-05 06:47:57 +00001428- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001429 (e.g., ``class C(): pass`` is no longer a syntax error).
1430 Patch #1176012 added support to the 'parser' module and 'compiler' package
1431 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001432
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001433- Patch #1115086: Support PY_LONGLONG in structmember.
1434
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001435- Bug #1155938: new style classes did not check that __init__() was
1436 returning None.
1437
Tim Petersecc6e6a2005-07-10 22:30:55 +00001438- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001439 ('\') with a specific error message.
1440
Martin v. Löwisff232d72005-03-03 09:24:38 +00001441- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1442
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001443- Bug #1124295: the __name__ attribute of file objects was
1444 inadvertently made inaccessible in restricted mode.
1445
Tim Petersecc6e6a2005-07-10 22:30:55 +00001446- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001447 an ferror() call.
1448
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001449- min() and max() now support key= arguments with the same meaning as in
1450 list.sort().
1451
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001452- The peephole optimizer now performs simple constant folding in expressions:
1453 (2+3) --> (5).
1454
Raymond Hettingera422c342005-01-11 03:03:27 +00001455- set and frozenset objects can now be marshalled. SF #1098985.
1456
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001457- Bug #1077106: Poor argument checking could cause memory corruption
1458 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001459
Jeremy Hyltonab630502005-02-04 18:44:06 +00001460- The parser did not complain about future statements in illegal
1461 positions. It once again reports a syntax error if a future
1462 statement occurs after anything other than a doc string.
1463
Neil Schemenauercf52c072005-08-12 17:34:58 +00001464- Change the %s format specifier for str objects so that it returns a
1465 unicode instance if the argument is not an instance of basestring and
1466 calling __str__ on the argument returns a unicode instance.
1467
Tim Petersf4e69282006-02-27 17:15:31 +00001468- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1469 current thread state when the auto-GIL-state machinery knows about
1470 it (since the thread state is being deleted, continuing to remember it
1471 can't help, but can hurt if another thread happens to get created with
1472 the same thread id).

1475-----------------
1476
Georg Brandl43f08a82006-03-31 18:01:16 +00001477- Patch #1380952: fix SSL objects timing out on consecutive read()s
1478
Neal Norwitz05a45592006-03-20 06:30:08 +00001479- Patch #1309579: wait3 and wait4 were added to the posix module.
1480
Anthony Baxterfa869072006-03-20 05:21:58 +00001481- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1482 In addition, the existing ulaw code was updated.
1483
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001484- RFE #567972: Socket objects' family, type and proto properties are

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001664- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1665 been renamed to have only a single underscore prefix. This was done to
1666 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001667
Nick Coghlan43832302006-04-23 17:04:07 +00001668- PEP 338: new module runpy defines a run_module function to support
1669 executing modules which provide access to source code or a code object
1670 via the PEP 302 import mechanisms.
1671
Anthony Baxter93f5b932006-04-03 08:05:07 +00001672- The email module's parsedate_tz function now sets the daylight savings

1680 in attribute values.
1681
Anthony Baxterc51ee692006-04-01 00:57:31 +00001682- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001683 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001684 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001685 module will not be built.
1686
Tim Petersc17976e2006-04-01 00:26:53 +00001687- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1688 aren't officially supported here, and trying to use them will probably
1689 raise an exception some day. But dicts have been allowed, and "mostly
1690 worked", so support for them won't go away without warning.
1691
Georg Brandl338ef7d2006-03-31 18:42:16 +00001692- Bug #1445068: getpass.getpass() can now be given an explicit stream
1693 argument to specify where to write the prompt.

1710
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001711- email 4.0 package now integrated. This is largely the same as the email 3.0
1712 package that was included in Python 2.3, except that PEP 8 module names are
1713 now used (e.g. mail.message instead of email.Message). The MIME classes
1714 have been moved to a subpackage (e.g. email.mime.text instead of
1715 email.MIMEText). The old names are still supported for now. Several
1716 deprecated Message methods have been removed and lots of bugs have been
1717 fixed. More details can be found in the email package documentation.
1718
Walter Dörwald40108c92006-03-27 08:15:44 +00001719- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1720 (a subclass of tuple) that provides incremental decoders and encoders
1721 (a way to use stateful codecs without the stream API). Python functions
1722 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1723 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1724 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001726- Patch #1359365: Calling next() on a closed StringIO.String object raises
1727 a ValueError instead of a StopIteration now (like file and cString.String do).
1728 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1729 called before (like file and StringIO.StringIO do).

1805 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1806 Ronald L. Rivest offered this advice for Python:
1807
1808 "The consensus of researchers in this area (at least as
1809 expressed at the NIST Hash Function Workshop 10/31/05),
1810 is that SHA-256 is a good choice for the time being, but
1811 that research should continue, and other alternatives may
1812 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001813

1994 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001995 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001996 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001997 + Dialect parameter parsing has been re-implemented to improve error

2000 dictates.
2001 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002002 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002003 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002004 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields

Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002006 + reader now allows \r characters to be quoted (previously it only allowed
2007 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002008 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002009 + Dialect classes passed to the module are no longer instantiated by
2010 the module before being parsed (the former validation scheme required
2011 this, but the mechanism was unreliable).
2012 + The dialect registry now contains instances of the internal
2013 C-coded dialect type, rather than references to python objects.
2014 + the internal c-coded dialect type is now immutable.
2015 + register_dialect now accepts the same keyword dialect specifications
2016 as the reader and writer, allowing the user to register dialects
2017 without first creating a dialect class.
2018 + a configurable limit to the size of parsed fields has been added -
2019 previously, an unmatched quote character could result in the entire
2020 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002021 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002022 the parser field size limit (returning the former limit). The initial
2023 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002024 + A line_num attribute has been added to the reader object, which tracks
2025 the number of lines read from the source iterator. This is not
2026 the same as the number of records returned, as records can span
2027 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002028 + reader and writer objects were not being registered with the cyclic-GC.
2029 This has been fixed.
2030
Brett Cannone6539c42005-01-08 02:43:53 +00002031- _DummyThread objects in the threading module now delete self.__block that is
2032 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2033 lock primitives tend to be limited in number and thus should not be wasted on
2034 a _DummyThread object. Fixes bug #1089632.
2035
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002036- The imghdr module now detects Exif files.
2037
Raymond Hettinger6065d322004-12-20 23:51:53 +00002038- StringIO.truncate() now correctly adjusts the size attribute.
2039 (Bug #951915).
2040
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002041- locale.py now uses an updated locale alias table (built using
2042 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2043 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002044 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002045
Raymond Hettinger3557f422004-12-07 12:02:02 +00002046- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2047
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002048- the pickle module no longer accepts the deprecated None option in the
2049 args tuple returned by __reduce__().
2050
Brett Cannon84667c02004-12-07 03:25:18 +00002051- optparse now optionally imports gettext. This allows its use in setup.py.
2052
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002053- the pickle module no longer uses the deprecated bin parameter.
2054
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002055- the shelve module no longer uses the deprecated binary parameter.
2056

2058
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002059- the filecmp module no longer uses the deprecated use_statcache argument.
2060
Raymond Hettinger664347b2004-12-04 21:21:53 +00002061- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2062 extended or overridden by subclasses. Formerly, the subclassed method would
2063 be ignored by the rest of the module. (Bug #1078905).
2064
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002065- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002066 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002067
Walter Dörwald36733692004-12-22 12:50:50 +00002068- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2069 once when a size argument is given. This prevents a buffer overflow in the
2070 tokenizer with very long source lines.
2071
Barry Warsaw538561e2006-01-01 21:48:54 +00002072- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2073 immediately after creating the object, without any intervening
2074 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002075
Skip Montanaro05885812005-01-16 20:48:27 +00002076- The reconvert.quote function can now emit triple-quoted strings. The
2077 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002078
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002079- ``UserString.MutableString`` now supports negative indices in
2080 ``__setitem__`` and ``__delitem__``
2081
Greg Ward40407942005-03-05 02:53:17 +00002082- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2083 correctly.
2084
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002085- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2086 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2087 character even if the user has passed a size parameter to get a proper
2088 line ending. Remove the special handling of a "\r\n" that has been split
2089 between two lines.
2090
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002091- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2092 about illegal code points. The codec now supports PEP 293 style error
2093 handlers.
2094
Walter Dörwald78a78b02005-09-01 12:04:29 +00002095- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002096 from the input stream, so that the output is a byte string in the correct
2097 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002098
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002099- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2100 considering it exactly like a '*'.
2101
Walter Dörwald007f8df2005-10-09 19:42:27 +00002102- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2103 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002104
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002105- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2106
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002107- Patch #1413711: Certain patterns of differences were making difflib
2108 touch the recursion limit.
2109
Walter Dörwald58917a62006-03-31 15:26:22 +00002110- Bug #947906: An object oriented interface has been added to the calendar
2111 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002112 called as a script (e.g. via ``python -mcalendar``). Localized month and
2113 weekday names can be ouput (even if an exotic encoding is used) using
2114 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002115

2117-----
2118
Neal Norwitz602d3392006-03-31 08:21:40 +00002119- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2120 by using -mieee gcc option.
2121
Martin v. Löwis86d66262006-02-17 08:40:11 +00002122- Patch #1432345: Make python compile on DragonFly.
2123
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002124- Build support for Win64-AMD64 was added.
2125
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002126- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2127
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002128- Patch #881820: look for openpty and forkpty also in libbsd.
2129
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002130- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2131 The zlib module is now builtin on Windows.
2132
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002133- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2134
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002135- Bug #1189330: configure did not correctly determine the necessary
2136 value of LINKCC if python was built with GCC 4.0.
2137
Trent Mick8321b422005-07-26 02:29:21 +00002138- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2139 vulnerability in zlib 1.2.1 and 1.2.2.
2140
Brett Cannon08cd5982005-04-24 22:26:38 +00002141- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2142 flags that change binary compatibility. Changes were also made to
2143 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002144 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002145
Bob Ippolitoed233462005-03-29 13:47:59 +00002146- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2147 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2148 no longer exists). This configure patch makes things right.
2149
Martin v. Löwise2713be2005-03-08 15:03:08 +00002150- Bug #1158607: Build with --disable-unicode again.
2151
Brett Cannon46d96232005-02-16 00:07:19 +00002152- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2153 defined. Discovered as a result of not being able to build on OS X.
2154
Brett Cannon516592f2004-12-07 00:42:59 +00002155- setup.py now uses the directories specified in LDFLAGS using the -L option
2156 and in CPPFLAGS using the -I option for adding library and include
2157 directories, respectively, for compiling extension modules against. This has
2158 led to the core being compiled using the values in CPPFLAGS. It also removes
2159 the need for the special-casing of both DarwinPorts and Fink for darwin since
2160 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2161 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2162 Fink, ``-I/opt/local/include`` for DarwinPorts).
2163
Brett Cannon43802422005-02-10 20:48:03 +00002164- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2165 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2166 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2167 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002169C API
2170-----
2171
Tim Petersc9d78aa2006-03-26 23:27:58 +00002172- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2173 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2174 is obtained via the ``PyObject_`` family, it must be released via the
2175 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2176 always been officially true, but when Python's small-object allocator was
2177 introduced, an attempt was made to cater to a few extension modules
2178 discovered at the time that obtained memory via ``PyObject_New`` but
2179 released it via ``PyMem_DEL``. It's years later, and if such code still
2180 exists it will fail now (probably with segfaults, but calling wrong
2181 low-level memory management functions can yield many symptoms).
2182
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002183- Added a C API for set and frozenset objects.
2184
Raymond Hettinger66517482004-12-03 11:45:13 +00002185- Removed PyRange_New().
2186
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002187- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2188 mapping argument now. This string is used as a mapping table. Byte values
2189 greater than the length of the string and 0xFFFE are treated as undefined
2190 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002197
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002198- Patch #1276356: New resource "urlfetch" is implemented. This enables
