20
Brett Cannon9adeab72006-09-20 18:34:28 +000021- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
22 allows calling unicode() on exceptions classes directly to succeed.
23
Georg Brandlec6c2df2006-09-11 09:38:35 +000024- Make _PyGILState_NoteThreadState() static, it was not used anywhere
25 outside of pystate.c and should not be necessary.
26
Georg Brandl4e933132006-09-06 20:05:58 +000027- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
28 Also make sure that every exception class has __module__ set to
29 'exceptions'.
30
Georg Brandl98775df2006-09-06 06:09:31 +000031- Bug #1550983: emit better error messages for erroneous relative
32 imports (if not in package and if beyond toplevel package).
33
Tim Petersc10c9d02006-09-05 02:18:09 +000034- Overflow checking code in integer division ran afoul of new gcc
35 optimizations. Changed to be more standard-conforming.

Neal Norwitzd34e4272006-09-05 02:36:20 +000041- The return tuple from str.rpartition(sep) is (tail, sep, head) where
42 head is the original string if sep was not found.
43
Neal Norwitzdac090d2006-09-05 03:53:08 +000044- Bug #1520864: unpacking singleton tuples in list comprehensions and
45 generator expressions (x for x, in ... ) works again. Fixing this problem
46 required changing the .pyc magic number. This means that .pyc files
47 generated before 2.5c2 will be regenerated.
48
Neal Norwitzca460d92006-09-06 06:28:06 +000049- with and as are now keywords.

Guido van Rossumc69ac252006-08-10 18:09:25 +0000140What's New in Python 2.5 release candidate 1?
141=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000142
Anthony Baxterb4096662006-08-16 03:42:26 +0000143*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000144
145Core and builtins
146-----------------
147
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000148- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000149 compared equal or unequal to a string and a UnicodeDecodeError
150 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000151
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000152 Instead, the equal (==) and unequal (!=) comparison operators will
153 now issue a UnicodeWarning and interpret the two objects as
154 unequal. The UnicodeWarning can be filtered as desired using
155 the warning framework, e.g. silenced completely, turned into an
156 exception, logged, etc.
157
158 Note that compare operators other than equal and unequal will still
159 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000160
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000161- Fix segfault when doing string formatting on subclasses of long.
162
163- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
164 with new-style classes.
165
166- Fix bug related to __len__ functions returning negative values with
167 classic classes.
168
169- Patch #1538606, Fix __index__() clipping. There were some problems
170 discovered with the API and how integers that didn't fit into Py_ssize_t
171 were handled. This patch attempts to provide enough alternatives
172 to effectively use __index__.
173
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000174- Bug #1536021: __hash__ may now return long int; the final hash
175 value is obtained by invoking hash on the long int.
176
Thomas Hellerab1049c2006-08-08 17:37:00 +0000177- Bug #1536786: buffer comparison could emit a RuntimeWarning.
178
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000179- Bug #1535165: fixed a segfault in input() and raw_input() when
180 sys.stdin is closed.
181
Thomas Heller74d36f02006-08-04 18:17:40 +0000182- On Windows, the PyErr_Warn function is now exported from
183 the Python dll again.
184
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000185- Bug #1191458: tracing over for loops now produces a line event
186 on each iteration. Fixing this problem required changing the .pyc
187 magic number. This means that .pyc files generated before 2.5c1
188 will be regenerated.
189
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000190- Bug #1333982: string/number constants were inappropriately stored
191 in the byte code and co_consts even if they were not used, ie
192 immediately popped off the stack.
193
Georg Brandle9462c72006-08-04 18:03:37 +0000194- Fixed a reference-counting problem in property().
195
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000196
197Library
198-------
199
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000200- Fix a bug in the ``compiler`` package that caused invalid code to be
201 generated for generator expressions.
202
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000203- The distutils version has been changed to 2.5.0. The change to
204 keep it programmatically in sync with the Python version running
205 the code (introduced in 2.5b3) has been reverted. It will continue
206 to be maintained manually as static string literal.
207
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000208- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000209 and this cannot be converted to the required C type, an exception is
210 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000211 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000212
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000213- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000214 an exception.
215
Tim Petersc10c9d02006-09-05 02:18:09 +0000216- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000217 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000218 workarounds for clocks with low resolution, to stop the code yielding
219 duplicate UUIDs.
220
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000221- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
222 before raising SystemExit, allowing IDLE to honor quit() and exit().
223
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000224- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
225
Georg Brandl7a1af772006-08-14 21:55:28 +0000226- Patch #1536071: trace.py should now find the full module name of a
227 file correctly even on Windows.
228
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000229- logging's atexit hook now runs even if the rest of the module has
230 already been cleaned up.
231
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000232- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000233
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000234- Bug #1531405, format_exception no longer raises an exception if
235 str(exception) raised an exception.
236
Neil Schemenauer06ded092006-08-04 16:20:30 +0000237- Fix a bug in the ``compiler`` package that caused invalid code to be
238 generated for nested functions.
239

251
Thomas Heller86720042006-08-14 11:17:48 +0000252- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
253 uses the _as_parameter_ attribute when objects are passed to foreign
254 function calls. The ctypes version number was changed to 1.0.1.
255
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000256- Bug #1530559, struct.pack raises TypeError where it used to convert.
257 Passing float arguments to struct.pack when integers are expected
258 now triggers a DeprecationWarning.
259

317 This provides the proper warning for struct.pack().
318 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
319
Neal Norwitz0d62a062006-07-30 06:53:31 +0000320- Patch #1531113: Fix augmented assignment with yield expressions.
321 Also fix a SystemError when trying to assign to yield expressions.
322
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000323- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
324 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
325 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
326 excessive filesystem operations during imports.
327
Tim Petersbc24eee2006-07-27 01:14:53 +0000328- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
329 operations on signed longs that are formally undefined by C.
330 Unfortunately, at least one compiler now cares about that, so complicated
331 the code to make that compiler happy again.
332
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000333- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
334
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000335- Patch #1232023: Stop including current directory in search
336 path on Windows.
337
Neal Norwitze1fdb322006-07-21 05:32:28 +0000338- Fix some potential crashes found with failmalloc.
339
Neal Norwitze7563102006-07-17 01:00:16 +0000340- Fix warnings reported by Klocwork's static analysis tool.
341
Neal Norwitz84be93b2006-07-16 01:50:38 +0000342- Bug #1512814, Fix incorrect lineno's when code within a function
343 had more than 255 blank lines.
344
Georg Brandl9dceedb2006-07-12 15:31:17 +0000345- Patch #1521179: Python now accepts the standard options ``--help`` and
346 ``--version`` as well as ``/?`` on Windows.
347
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000348- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000349 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000350 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000351
Tim Peters112aad32006-07-19 00:03:19 +0000352- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000353 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000354 new ``sys._current_frames()`` returns a dictionary with one entry,
355 mapping the faux "thread id" 0 to the current frame.
356
Ronald Oussoren3075e162006-07-25 20:28:55 +0000357- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

361-------
362
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000363- Correction of patch #1455898: In the mbcs decoder, set final=False
364 for stream decoder, but final=True for the decode function.
365
Georg Brandl07fec3a2006-08-01 18:49:24 +0000366- os.urandom no longer masks unrelated exceptions like SystemExit or
367 KeyboardInterrupt.
368
Tim Peters4643c2f2006-08-10 22:45:34 +0000369- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000370 shutil.copytree on Windows
371
Georg Brandle34ac7c2006-07-30 11:07:23 +0000372- Bug #1002398: The documentation for os.path.sameopenfile now correctly
373 refers to file descriptors, not file objects.
374
Tim Petersc10c9d02006-09-05 02:18:09 +0000375- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000376 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000377 #1513611, and probably others.
378
Georg Brandledd9b0d2006-07-29 09:33:26 +0000379- Bug #1441397: The compiler module now recognizes module and function
380 docstrings correctly as it did in Python 2.4.
381
Tim Peters6f681472006-07-27 23:44:37 +0000382- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
383 lost that tests are sorted by name before being run. This rarely
384 matters for well-written tests, but can create baffling symptoms if
385 side effects from one test to the next affect outcomes. ``DocTestFinder``
386 has been changed to sort the list of tests it returns.
387
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000388- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000389 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000390
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000391- Bug #978833: Really close underlying socket in _socketobject.close.
392
Georg Brandl8c036cc2006-08-20 13:15:39 +0000393- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
394 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000395
Georg Brandlcf0c1722006-07-26 07:23:32 +0000396- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
397 to recursive calls and call it with the failing package name.
398
Martin v. Löwis0b483032006-07-25 09:53:12 +0000399- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
400
Georg Brandlc13c34c2006-07-24 14:09:56 +0000401- Patch #1515343: Fix printing of deprecated string exceptions with a
402 value in the traceback module.
403
Greg Ward48fae7a2006-07-23 16:05:51 +0000404- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
405
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000406- Patch #1524429: Use repr() instead of backticks in Tkinter again.
407
Brett Cannoncaebe222006-07-18 04:41:36 +0000408- Bug #1520914: Change time.strftime() to accept a zero for any position in its
409 argument tuple. For arguments where zero is illegal, the value is forced to
410 the minimum value that is correct. This is to support an undocumented but
411 common way people used to fill in inconsequential information in the time
412 tuple pre-2.4.
413
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000414- Patch #1220874: Update the binhex module for Mach-O.
415
Barry Warsawb110bad2006-07-21 14:51:07 +0000416- The email package has improved RFC 2231 support, specifically for
417 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
418 (name*0=<blah>) parameter continuations. This may change the types of
419 values returned from email.message.Message.get_param() and friends.
420 Specifically in some cases where non-encoded continuations were used,
421 get_param() used to return a 3-tuple of (None, None, string) whereas now it
422 will just return the string (since non-encoded continuations don't have
423 charset and language parts).
424
425 Also, whereas % values were decoded in all parameter continuations, they are
426 now only decoded in encoded parameter parts.
427
Ronald Oussoren3075e162006-07-25 20:28:55 +0000428- Bug #1517990: IDLE keybindings on MacOS X now work correctly
429
430- Bug #1517996: IDLE now longer shows the default Tk menu when a
431 path browser, class browser or debugger is the frontmost window on MacOS X
432
Barry Warsaw00decd72006-07-27 23:43:15 +0000433- Patch #1520294: Support for getset and member descriptors in types.py,
434 inspect.py, and pydoc.py. Specifically, this allows for querying the type
435 of an object against these built-in types and more importantly, for getting
436 their docstrings printed in the interactive interpreter's help() function.

440-----------------
441
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000442- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
443 a socket operation on a socket with a timeout, the exception will be
444 caught correctly. Previously, the exception was not caught.
445
Thomas Heller1393d6a2006-07-28 21:43:20 +0000446- Patch #1529514: The _ctypes extension is now compiled on more
447 openbsd target platforms.
448
Tim Peters9cab5932006-07-28 00:30:00 +0000449- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
450 a memory leak, affecting pickles and deep copies.
451
Tim Petersbc24eee2006-07-27 01:14:53 +0000452- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000453 Paul Eggert.
454
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000455- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
456
Thomas Hellerce049a02006-07-14 17:51:14 +0000457- Patch #1521817: Index range checking on ctypes arrays containing
458 exactly one element enabled again. This allows iterating over these
459 arrays, without the need to check the array size before.
460
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000461- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000462 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000463 /dev/null in certain cases; this is now fixed.
464
Thomas Heller47d7a062006-07-12 08:43:47 +0000465- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
466 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000467
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000468- Because of a misspelled preprocessor symbol, ctypes was always
469 compiled without thread support; this is now fixed.
470
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000471- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
472 methods now allow their database parameter to be None as the
473 sleepycat API allows.
474
Matt Flemingec926502006-07-28 11:27:27 +0000475- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
476 bluetooth API compared with Linux and FreeBSD.
477
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000478Tests
479-----
480
481- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
482 how long the test file should take to play. Now accepts taking 2.93 secs
483 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
484
Georg Brandl4793aa32006-07-28 18:31:39 +0000485- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
486 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
487 run via ``regrtest.py``. Now they do.

495---
496
497- PythonLauncher now works correctly when the path to the script contains
498 characters that are treated specially by the shell (such as quotes).
499
500- Bug #1527397: PythonLauncher now launches scripts with the working directory
501 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000502 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000503 expect.

512-----------------
513
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000514- Bug #1441486: The literal representation of -(sys.maxint - 1)
515 again evaluates to a int object, not a long.
516
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000517- Bug #1501934: The scope of global variables that are locally assigned
518 using augmented assignment is now correctly determined.
519
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000520- Bug #927248: Recursive method-wrapper objects can now safely
521 be released.
522
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000523- Bug #1417699: Reject locale-specific decimal point in float()
524 and atof().
525
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000526- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
527 omit a default "error" argument for NULL pointer. This allows
528 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000529
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000530- Bug #1519018: 'as' is now validated properly in import statements.
531
Neal Norwitz28746ab2006-07-09 22:14:42 +0000532- On 64 bit systems, int literals that use less than 64 bits are
533 now ints rather than longs.
534
Neal Norwitzed657552006-07-10 00:04:44 +0000535- Bug #1512814, Fix incorrect lineno's when code at module scope
536 started after line 256.
537
Tim Peters32a83612006-07-10 21:08:24 +0000538- New function ``sys._current_frames()`` returns a dict mapping thread
539 id to topmost thread stack frame. This is for expert use, and is
540 especially useful for debugging application deadlocks. The functionality
541 was previously available in Fazal Majid's ``threadframe`` extension
542 module, but it wasn't possible to do this in a wholly threadsafe way from
543 an extension.

547
Martin v. Löwis77621582006-07-30 13:27:31 +0000548- Bug #1257728: Mention Cygwin in distutils error message about a missing
549 VS 2003.
550

552
Tim Peters32a83612006-07-10 21:08:24 +0000553- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000554 environment variable to be set in order to the SDK environment
555 for finding the compiler, include files, etc.

Nick Coghlan2d792252006-07-06 13:47:18 +0000559- warnings.py now ignores ImportWarning by default
560
Thomas Woutersadd19112006-07-05 11:03:49 +0000561- string.Template() now correctly handles tuple-values. Previously,
562 multi-value tuples would raise an exception and single-value tuples would
563 be treated as the value they contain, instead.
564
Martin v. Löwisede77f52006-07-03 13:01:35 +0000565- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
566 even if some data are received.
567
Martin v. Löwis45482392006-07-03 12:28:58 +0000568- Bug #1267547: Put proper recursive setup.py call into the

572 degrees and radians.
573
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000574- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000575 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000576
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000577- Bug #1514703: Only setup canvas window in turtle when the canvas
578 is created.
579
Martin v. Löwis7596e832006-07-01 15:33:37 +0000580- Bug #1513223: .close() of a _socketobj now releases the underlying
581 socket again, which then gets closed as it becomes unreferenced.
582
Fred Drake10497c82006-06-29 02:57:48 +0000583- Bug #1504333: Make sgmllib support angle brackets in quoted
584 attribute values.
585
586- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
587 sgmllib ('[' and ']' were not accepted).
588
Georg Brandl1be63af2006-06-28 20:23:25 +0000589- Fix a bug in the turtle module's end_fill function.
590
Brett Cannon53ab5b72006-06-22 16:49:14 +0000591- Bug #1510580: The 'warnings' module improperly required that a Warning
592 category be either a types.ClassType and a subclass of Warning. The proper
593 check is just that it is a subclass with Warning as the documentation states.
594
Georg Brandlad29e632006-06-21 17:45:17 +0000595- The compiler module now correctly compiles the new try-except-finally
596 statement (bug #1509132).
597
Neal Norwitz60373cd2006-06-22 06:30:50 +0000598- The wsgiref package is now installed properly on Unix.
599
Vinay Sajip28e57612006-07-01 10:45:20 +0000600- A bug was fixed in logging.config.fileConfig() which caused a crash on
601 shutdown when fileConfig() was called multiple times.
602
Gerhard Häring762fbd32006-07-02 17:48:30 +0000603- The sqlite3 module did cut off data from the SQLite database at the first
604 null character before sending it to a custom converter. This has been fixed
605 now.

Tim Peters112aad32006-07-19 00:03:19 +0000610- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
611 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
612 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000613
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000614- Assigning None to pointer type fields in ctypes structures possible
615 overwrote the wrong fields, this is fixed now.
616
617- Fixed a segfault in _ctypes when ctypes.wintypes were imported
618 on non-Windows platforms.
619
620- Bug #1518190: The ctypes.c_void_p constructor now accepts any
621 integer or long, without range checking.
622
623- Patch #1517790: It is now possible to use custom objects in the ctypes
624 foreign function argtypes sequence as long as they provide a from_param
625 method, no longer is it required that the object is a ctypes type.
626
627- The '_ctypes' extension module now works when Python is configured
628 with the --without-threads option.
629
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000630- Bug #1513646: os.access on Windows now correctly determines write
631 access, again.
632
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000633- Bug #1512695: cPickle.loads could crash if it was interrupted with
634 a KeyboardInterrupt.
635
Neal Norwitza12aa882006-07-06 06:45:08 +0000636- Bug #1296433: parsing XML with a non-default encoding and
637 a CharacterDataHandler could crash the interpreter in pyexpat.
638
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000639- Patch #1516912: improve Modules support for OpenVMS.

642-----
643
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000644- Automate Windows build process for the Win64 SSL module.
645
Tim Peters32a83612006-07-10 21:08:24 +0000646- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000647 Previously, the slight difference could cause compilation errors of the
648 'zlib' module on systems with more than one version of zlib.
649
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000650- The MSI compileall step was fixed to also support a TARGETDIR
651 with spaces in it.
652
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000653- Bug #1517388: sqlite3.dll is now installed on Windows independent
654 of Tcl/Tk.
655
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000656- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000657 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +0000659Tests
660-----
661
662- Call os.waitpid() at the end of tests that spawn child processes in order
663 to minimize resources (zombies).
664
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000665Documentation
666-------------
667
Nick Coghlan2d792252006-07-06 13:47:18 +0000668- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
669 documentation for the warnings module.
670
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000671- Patch #1509163: MS Toolkit Compiler no longer available.
672
Neal Norwitz56640df2006-07-10 02:36:41 +0000673- Patch #1504046: Add documentation for xml.etree.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000678
Anthony Baxterd1136802006-06-19 12:04:15 +0000679*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000680
681Core and builtins
682-----------------
683
Georg Brandla56b9152006-06-19 06:35:54 +0000684- Patch #1507676: Error messages returned by invalid abstract object operations
685 (such as iterating over an integer) have been improved and now include the
686 type of the offending object to help with debugging.
687
Brett Cannonea3912b2006-06-13 21:46:41 +0000688- Bug #992017: A classic class that defined a __coerce__() method that returned
689 its arguments swapped would infinitely recurse and segfault the interpreter.
690
Neal Norwitz909eb122006-06-12 02:13:21 +0000691- Fix the socket tests so they can be run concurrently.
692
Neal Norwitzb9845e72006-06-12 02:11:18 +0000693- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000694 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000695
Brett Cannon22565aa2006-06-09 22:31:23 +0000696- Bug #532646: object.__call__() will continue looking for the __call__
697 attribute on objects until one without one is found. This leads to recursion
698 when you take a class and set its __call__ attribute to an instance of the
699 class. Originally fixed for classic classes, but this fix is for new-style.
700 Removes the infinite_rec_3 crasher.
701
Georg Brandl24250812006-06-09 18:45:48 +0000702- The string and unicode methods startswith() and endswith() now accept
703 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
704
Brett Cannonde3b0522006-06-08 17:00:45 +0000705- Buffer objects, at the C level, never used the char buffer
706 implementation even when the char buffer for the wrapped object was
707 explicitly requested (originally returned the read or write buffer).
708 Now a TypeError is raised if the char buffer is not present but is
709 requested.
710
Georg Brandlddbaa662006-06-04 21:56:52 +0000711- Patch #1346214: Statements like "if 0: suite" are now again optimized
712 away like they were in Python 2.4.
713
Georg Brandlb7c8f542006-05-27 12:30:25 +0000714- Builtin exceptions are now full-blown new-style classes instead of
715 instances pretending to be classes, which speeds up exception handling
716 by about 80% in comparison to 2.5a2.
717
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000718- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
719 Unicode 4.1.
720
Georg Brandlf4ef1162006-05-26 18:03:31 +0000721- Patch #921466: sys.path_importer_cache is now used to cache valid and
722 invalid file paths for the built-in import machinery which leads to
723 fewer open calls on startup.
724
Tim Peters696cf432006-05-24 21:10:40 +0000725- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
726 of-2 bases. The largest speedup is for inputs with about 1000 decimal
727 digits. Conversion from non-power-of-2 bases remains quadratic-time in
728 the number of input digits (it was and remains linear-time for bases
729 2, 4, 8, 16 and 32).
730
Tim Petersb713ec22006-05-23 18:45:30 +0000731- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
732 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
733 an integer close to ``sys.maxint``. This was repaired by patch
734 #1335972, which also gives a nice speedup.
735
Richard Jonescebbefc2006-05-23 18:28:17 +0000736- Patch #1337051: reduced size of frame objects.
737
738- PyErr_NewException now accepts a tuple of base classes as its
739 "base" parameter.
740
Richard Jones7c88dcc2006-05-23 10:37:38 +0000741- Patch #876206: function call speedup by retaining allocated frame
742 objects.
743
Georg Brandl7b90e162006-05-18 07:01:27 +0000744- Bug #1462152: file() now checks more thoroughly for invalid mode
745 strings and removes a possible "U" before passing the mode to the
746 C library function.
747
Neal Norwitz1004a532006-05-15 07:17:23 +0000748- Patch #1488312, Fix memory alignment problem on SPARC in unicode
749
Neal Norwitz373f0a72006-05-15 07:04:36 +0000750- Bug #1487966: Fix SystemError with conditional expression in assignment
751
Martin v. Löwis879768d2006-05-11 13:28:43 +0000752- WindowsError now has two error code attributes: errno, which carries
753 the error values from errno.h, and winerror, which carries the error
754 values from winerror.h. Previous versions put the winerror.h values
755 (from GetLastError()) into the errno attribute.
756
Martin v. Löwis77736712006-05-04 05:51:03 +0000757- Patch #1475845: Raise IndentationError for unexpected indent.
758
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000759- Patch #1479181: split open() and file() from being aliases for each other.
760
Tim Peters44bd9862006-06-01 13:49:23 +0000761- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
762 methods were always silently ignored by dictionaries when comparing keys.
763 They are now passed through (except when using the C API function
764 ``PyDict_GetItem()``, whose semantics did not change).
765
766- Bug #1456209: In some obscure cases it was possible for a class with a
767 custom ``__eq__()`` method to confuse dict internals when class instances
768 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
769 No, you don't have any code that did this ;-)

775
776- Patch #1462338: Upgrade pyexpat to expat 2.0.0
777
Brett Cannon6ee7d012006-06-08 16:23:04 +0000778- Change binascii.hexlify to accept a read-only buffer instead of only a char
779 buffer and actually follow its documentation.
780
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000781- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
782
Nick Coghlanc649ec52006-05-29 12:43:05 +0000783- Patch #1478788 (modified version): The functional extension module has
784 been renamed to _functools and a functools Python wrapper module added.
785 This provides a home for additional function related utilities that are
786 not specifically about functional programming. See PEP 309.
787
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000788- Patch #1493701: performance enhancements for struct module.
789
Georg Brandl378d5922006-05-17 14:26:50 +0000790- Patch #1490224: time.altzone is now set correctly on Cygwin.
791
Georg Brandl8d3342b2006-05-16 07:38:27 +0000792- Patch #1435422: zlib's compress and decompress objects now have a
793 copy() method.
794
Andrew MacIntyre92913322006-06-13 15:04:24 +0000795- Patch #1454481: thread stack size is now tunable at runtime for thread
796 enabled builds on Windows and systems with Posix threads support.
797
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000798- On Win32, os.listdir now supports arbitrarily-long Unicode path names
799 (up to the system limit of 32K characters).
800
801- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
802 As a result, these functions now raise WindowsError instead of OSError.
803
Tim Peters7a822da2006-05-25 21:50:17 +0000804- ``time.clock()`` on Win64 should use the high-performance Windows
805 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
806 Windows platforms).
807
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000808- Calling Tk_Init twice is refused if the first call failed as that
809 may deadlock.
810
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000811- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
812 accept it without potentially using an uninitialized pointer.
813
814- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
815 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
816 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000817
Gregory P. Smith372b5832006-06-05 18:48:21 +0000818- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000819 [pybsddb project SF patch number 1466734]
820
Gregory P. Smith372b5832006-06-05 18:48:21 +0000821- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
822 parameter is supplied. [SF pybsddb bug #1477863]
823
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000824- bsddb: the __len__ method of a DB object has been fixed to return correct
825 results. It could previously incorrectly return 0 in some cases.
826 Fixes SF bug 1493322 (pybsddb bug 1184012).
827
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000828- bsddb: the bsddb.dbtables Modify method now raises the proper error and
829 aborts the db transaction safely when a modifier callback fails.
830 Fixes SF python patch/bug #1408584.
831
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000832- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000833 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000834 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
835 database calls that would previously deadlock. [SF python bug #775414]
836
Vinay Sajip28e57612006-07-01 10:45:20 +0000837- Patch #1446489: add support for the ZIP64 extensions to zipfile.

840 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000841
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000842Library
843-------
844
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000845- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
846 functions.
847
Martin v. Löwis3798da02006-06-17 18:44:27 +0000848- Patch #812986: Update turtle output even if not tracing.
849
Vinay Sajip28e57612006-07-01 10:45:20 +0000850- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000851 Tkinter.BaseWidget.
852
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000853- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
854
Martin v. Löwis337487e2006-06-17 09:15:14 +0000855- Patch #763580: Add name and value arguments to Tkinter variable
856 classes.
857
Georg Brandl83cc0d02006-06-14 08:50:03 +0000858- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
859 mime.types file for determining MIME types.
860
Georg Brandl2605ca82006-06-14 06:08:31 +0000861- Bug #1339007: Shelf objects now don't raise an exception in their
862 __del__ method when initialization failed.
863
Martin v. Löwisd8251432006-06-14 05:21:04 +0000864- Patch #1455898: The MBCS codec now supports the incremental mode for
865 double-byte encodings.
866
Tim Peters43898b42006-06-14 04:09:25 +0000867- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
868 guarantee that adjacent triples in the return list always describe
869 non-adjacent blocks. Previously, a pair of matching blocks could end
870 up being described by multiple adjacent triples that formed a partition
871 of the matching pair.
872
Greg Ward0e0c9f42006-06-11 16:24:11 +0000873- Bug #1498146: fix optparse to handle Unicode strings in option help,
874 description, and epilog.
875
Greg Wardd1c797e2006-06-11 14:42:41 +0000876- Bug #1366250: minor optparse documentation error.
877
Greg Ward7f547402006-06-11 00:40:49 +0000878- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
879 clarify docs.
880
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000881- The wsgiref package has been added to the standard library.
882
Nick Coghlan676725d2006-06-08 13:54:49 +0000883- The functions update_wrapper() and wraps() have been added to the functools
884 module. These make it easier to copy relevant metadata from the original
885 function when writing wrapper functions.
886
Tim Petersd6a9eef2006-06-05 01:48:21 +0000887- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
888 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000889
Martin v. Löwis3f767792006-06-04 19:36:28 +0000890- Patch #1359618: Speed up charmap encoder by using a trie structure
891 for lookup.
892
Tim Petersd609b1a2006-06-02 23:22:51 +0000893- The functions in the ``pprint`` module now sort dictionaries by key
894 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
895 if and only if its display required more than one line, although that
896 wasn't documented. The new behavior increases predictability; e.g.,
897 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
898
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000899- Patch #1497027: try HTTP digest auth before basic auth in urllib2
900 (thanks for J. J. Lee).
901
Georg Brandl2b330372006-05-28 20:23:12 +0000902- Patch #1496206: improve urllib2 handling of passwords with respect to
903 default HTTP and HTTPS ports.
904
George Yoshidaf3c65de2006-05-28 16:39:09 +0000905- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
906

908
Georg Brandlb89316f2006-05-17 15:51:16 +0000909- Patch #1180296: Two new functions were added to the locale module:
910 format_string() to get the effect of "format % items" but locale-aware,
911 and currency() to format a monetary number with currency sign.
912
Georg Brandle3a25832006-05-17 14:56:04 +0000913- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
914 and several features added, such as speed and geometry control.
915
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000916- Patch #1488881: add support for external file objects in bz2 compressed
917 tarfiles.
918
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000919- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
920 stdout arguments, making it possible to redirect input and output
921 for remote debugging.
922
923- Patch #1484695: Update the tarfile module to version 0.8. This fixes
924 a couple of issues, notably handling of long file names using the
925 GNU LONGNAME extension.
926

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000969What's New in Python 2.5 alpha 2?
970=================================
971
972*Release date: 27-APR-2006*
973
974Core and builtins
975-----------------
976
Thomas Heller1b046642006-04-18 18:51:06 +0000977- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
978 by converting these apis from macros into exported functions again:
979
980 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
981 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
982 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
983 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
984 PyRun_String Py_CompileString
985
Martin v. Löwis45294a92006-04-18 06:24:08 +0000986- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
987
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000988- All uses of PyStructSequence_InitType have been changed to initialize
989 the type objects only once, even if the interpreter is initialized
990 multiple times.
991
Neal Norwitz61546162006-04-14 05:20:28 +0000992- Bug #1454485, array.array('u') could crash the interpreter. This was
993 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
994 to unicode when it didn't make sense. 'u#' now requires a unicode string.
995
996- Py_UNICODE is unsigned. It was always documented as unsigned, but
997 due to a bug had a signed value in previous versions.
998
Tim Peters3a5e8b12006-04-11 01:44:07 +0000999- Patch #837242: ``id()`` of any Python object always gives a positive
1000 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1001 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001002 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001003 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001004
Tim Peters3a5e8b12006-04-11 01:44:07 +00001005 def __hash__(self):
1006 return id(self) # WRONG
1007
1008 because a hash result must be a (short) Python int but it was always
1009 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001010 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001011 was always usable as a hash value before this patch. That's no longer
1012 necessarily so.
1013
1014- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001015 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001016 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001017 #1454844)
1018
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001019- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1020 involving generators that have paused outside of any ``try`` or ``with``
1021 blocks. (In 2.5a1, a paused generator that was part of a reference
1022 cycle could not be garbage collected, regardless of whether it was
1023 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001024
Anthony Baxter51bcb682006-04-05 14:51:42 +00001025Extension Modules

1027
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001028- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1029 is a macro.
1030
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001031- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1032 fails with an error condition.
1033
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001034- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1035
1036- Bug #1117761: bsddb.*open() no longer raises an exception when using
1037 the cachesize parameter.
1038
1039- Bug #1149413: bsddb.*open() no longer raises an exception when using
1040 a temporary db (file=None) with the 'n' flag to truncate on open.
1041
1042- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1043 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001044
Armin Rigoa9017c32006-04-19 11:50:27 +00001045- Patch #1062014: AF_UNIX sockets under Linux have a special
1046 abstract namespace that is now fully supported.
1047

1049-------
1050
Peter Astrand7d1d4362006-07-14 14:04:45 +00001051- Bug #1223937: subprocess.CalledProcessError reports the exit status
1052 of the process using the returncode attribute, instead of
1053 abusing errno.
1054
Tim Peters711bf302006-04-25 03:31:36 +00001055- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1056 a doctest to be skipped (the code is not run, and the expected output
1057 or exception is ignored).
1058
Nick Coghlanda2268f2006-04-24 04:37:15 +00001059- Fixed contextlib.nested to cope with exceptions being raised and
1060 caught inside exit handlers.
1061
Greg Wardab05edc2006-04-23 03:47:58 +00001062- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1063 hex, octal, or binary; add ``append_const`` action; keep going if
1064 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1065 added ``epilog`` for better help generation).
1066
Tim Peters21fbd572006-04-21 21:18:10 +00001067- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1068 called from a thread spawned as a side effect of importing a module.
1069
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001070- The pydoc module now supports documenting packages contained in
1071 .zip or .egg files.
1072
1073- The pkgutil module now has several new utility functions, such
1074 as ``walk_packages()`` to support working with packages that are either
1075 in the filesystem or zip files.
1076
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001077- The mailbox module can now modify and delete messages from
1078 mailboxes, in addition to simply reading them. Thanks to Gregory
1079 K. Johnson for writing the code, and to the 2005 Google Summer of
1080 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001081
Tim Petersc7605f22006-04-17 21:12:33 +00001082- The ``__del__`` method of class ``local`` in module ``_threading_local``
1083 returned before accomplishing any of its intended cleanup.
1084
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001085- Patch #790710: Add breakpoint command lists in pdb.
1086
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001087- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1088
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001089- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1090
Anthony Baxtere29002c2006-04-12 12:07:31 +00001091- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1092 Windows. Bug #1469163.
1093
Phillip J. Eby47032112006-04-11 01:07:43 +00001094- The warnings, linecache, inspect, traceback, site, and doctest modules
1095 were updated to work correctly with modules imported from zipfiles or
1096 via other PEP 302 __loader__ objects.
1097
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001098- Patch #1467770: Reduce usage of subprocess._active to processes which
1099 the application hasn't waited on.
1100
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001101- Patch #1462222: Fix Tix.Grid.

Neal Norwitza31bf182006-04-09 03:35:43 +00001103- Fix exception when doing glob.glob('anything*/')
1104
Skip Montanaro262fb922006-04-21 02:31:07 +00001105- The pstats.Stats class accepts an optional stream keyword argument to
1106 direct output to an alternate file-like object.
1107

1110
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001111- The Makefile now has a reindent target, which runs reindent.py on
1112 the library.
1113
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001114- Patch #1470875: Building Python with MS Free Compiler
1115
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001116- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001117
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001118- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1119 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001120 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001121 CXX from --with-cxx-main, see description in README.
1122
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001123- Patch #1429775: Link extension modules with the shared libpython.
1124
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001125- Fixed a libffi build problem on MIPS systems.
1126
Tim Peters8931ff12006-05-13 23:28:20 +00001127- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1128 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1129 and "%zu" for unsigned integers of type ``size_t``.
1130
Anthony Baxter51bcb682006-04-05 14:51:42 +00001131Tests
1132-----
1133
Nick Coghlanda2268f2006-04-24 04:37:15 +00001134- test_contextlib now checks contextlib.nested can cope with exceptions
1135 being raised and caught inside exit handlers.
1136
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001137- test_cmd_line now checks operation of the -m and -c command switches
1138
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001139- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1140 it separately and by hand. It also wasn't cleaning up its changes to
1141 the current Decimal context.
1142
Thomas Woutersabd08882006-04-26 15:53:30 +00001143- regrtest.py now has a -M option to run tests that test the new limits of
1144 containers, on 64-bit architectures. Running these tests is only sensible
1145 on 64-bit machines with more than two gigabytes of memory. The argument
1146 passed is the maximum amount of memory for the tests to use.

Tim Petersb06d28c2006-05-12 01:57:59 +00001157- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1158
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001159- PEP 343: Added Context Types section to the library reference
1160 and attempted to bring other PEP 343 related documentation into
1161 line with the implementation and/or python-dev discussions.
1162
Tim Peters8dc73d22006-04-24 02:03:16 +00001163- Bug #1337990: clarified that ``doctest`` does not support examples
1164 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001167What's New in Python 2.5 alpha 1?
1168=================================
1169
Anthony Baxterebed3f62006-04-03 15:03:44 +00001170*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001171
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001172Core and builtins
1173-----------------
1174
Nick Coghlan43832302006-04-23 17:04:07 +00001175- PEP 338: -m command line switch now delegates to runpy.run_module
1176 allowing it to support modules in packages and zipfiles
1177
Martin v. Löwisc661b882006-04-20 04:54:23 +00001178- On Windows, .DLL is not an accepted file name extension for
1179 extension modules anymore; extensions are only found if they
1180 end in .PYD.
1181
Martin v. Löwisea62d252006-04-03 10:56:49 +00001182- Bug #1421664: sys.stderr.encoding is now set to the same value as
1183 sys.stdout.encoding.
1184
Neal Norwitz92e212f2006-04-03 04:48:37 +00001185- __import__ accepts keyword arguments.
1186
Georg Brandlccadf842006-03-31 18:54:53 +00001187- Patch #1460496: round() now accepts keyword arguments.
1188
Anthony Baxter262c00a2006-03-30 10:53:17 +00001189- Fixed bug #1459029 - unicode reprs were double-escaped.
1190
Hye-Shik Changd478f342006-03-23 12:32:36 +00001191- Patch #1396919: The system scope threads are reenabled on FreeBSD
1192 5.4 and later versions.
1193
Neal Norwitze98ccf62006-03-23 05:39:47 +00001194- Bug #1115379: Compiling a Unicode string with an encoding declaration
1195 now gives a SyntaxError.
1196
Georg Brandlabd1ff82006-03-18 07:59:59 +00001197- Previously, Python code had no easy way to access the contents of a
1198 cell object. Now, a ``cell_contents`` attribute has been added
1199 (closes patch #1170323).
1200
Tim Peterscf79aac2006-03-16 01:14:46 +00001201- Patch #1123430: Python's small-object allocator now returns an arena to
1202 the system ``free()`` when all memory within an arena becomes unused
1203 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1204 freed. Some applications will see a drop in virtual memory size now,
1205 especially long-running applications that, from time to time, temporarily
1206 use a large number of small objects. Note that when Python returns an
1207 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001208 platform C library will in turn return that memory to the operating system.
1209 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001210 appears to be effective at least on Microsoft C and gcc-based systems.
1211 Thanks to Evan Jones for hard work and patience.
1212
Georg Brandl533ff6f2006-03-08 18:09:27 +00001213- Patch #1434038: property() now uses the getter's docstring if there is
1214 no "doc" argument given. This makes it possible to legitimately use
1215 property() as a decorator to produce a read-only property.
1216
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001217- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1218 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1219 of requiring an int or long in slicing and a few other contexts, enabling
1220 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1221
Neal Norwitz995acdf2006-03-07 05:01:00 +00001222- Fixed various bugs reported by Coverity's Prevent tool.
1223
Brett Cannonbf364092006-03-01 04:25:17 +00001224- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1225 new exception base class, BaseException, which has a new message attribute.
1226 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1227 Raising a string exception now raises a DeprecationWarning.
1228
Thomas Woutersfb609f42006-02-28 16:37:25 +00001229- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1230 explicitly relative, using 'from .module import name' to mean 'from the same
1231 package as this module is in. Imports without dots still default to the
1232 old relative-then-absolute, unless 'from __future__ import
1233 absolute_import' is used.
1234
Brett Cannona7446e32006-02-27 23:39:10 +00001235- Properly check if 'warnings' raises an exception (usually when a filter set
1236 to "error" is triggered) when raising a warning for raising string
1237 exceptions.
1238
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001239- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001240 The name was removed from Include/code.h.
1241
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001242- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001243
Guido van Rossum1968ad32006-02-25 22:38:04 +00001244- Patch 1433928:
1245 - The copy module now "copies" function objects (as atomic objects).
1246 - dict.__getitem__ now looks for a __missing__ hook before raising
1247 KeyError.
1248
Tim Peters84ef21c2006-02-28 20:39:06 +00001249- PEP 343: with statement implemented. Needs ``from __future__ import
1250 with_statement``. Use of 'with' as a variable will generate a warning.
1251 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001252 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001253 The following objects have __context__ methods:
1254 - The built-in file type.
1255 - The thread.LockType type.
1256 - The following types defined by the threading module:
1257 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1258 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001259
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001260- Fix the encodings package codec search function to only search
1261 inside its own package. Fixes problem reported in patch #1433198.
1262
1263 Note: Codec packages should implement and register their own
1264 codec search function. PEP 100 has the details.
1265
Tim Peters9ea89d22006-06-04 03:26:02 +00001266- PEP 353: Using ``Py_ssize_t`` as the index type.
1267
1268- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1269 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1270 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1271 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1272 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001273
Neal Norwitzfc76d632006-01-10 06:03:13 +00001274- Patch #1400181, fix unicode string formatting to not use the locale.
1275 This is how string objects work. u'%f' could use , instead of .
1276 for the decimal point. Now both strings and unicode always use periods.
1277
Neal Norwitz671b9e32006-01-09 07:07:12 +00001278- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1279 configure would break checking curses.h.
1280
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001281- Bug #959576: The pwd module is now builtin. This allows Python to be
1282 built on UNIX platforms without $HOME set.
1283
Neal Norwitzc10978f2005-12-19 06:07:16 +00001284- Bug #1072182, fix some potential problems if characters are signed.
1285
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001286- Bug #889500, fix line number on SyntaxWarning for global declarations.
1287
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001288- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1289
Neal Norwitze7214a12005-12-18 05:03:17 +00001290- Support for converting hex strings to floats no longer works.
1291 This was not portable. float('0x3') now raises a ValueError.
1292
Barry Warsaw2a38a862005-12-18 01:27:35 +00001293- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001294 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001295 is now displayed in interactive prompt banner.
1296
Georg Brandlfa166682005-12-17 21:45:17 +00001297- Implementation of PEP 341 - Unification of try/except and try/finally.
1298 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001299 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001300
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001301- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1302 now encodes backslash correctly.
1303
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001304- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1305
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001306- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001307 and long longs.
1308
Neal Norwitz67715f02005-11-09 06:59:35 +00001309- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001310 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001311 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001312
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001313- Replaced most Unicode charmap codecs with new ones using the
1314 new Unicode translate string feature in the builtin charmap
1315 codec; the codecs were created from the mapping tables available
1316 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1317 encodings now include a mapping for the Apple logo)
1318
Tim Peterse3547fd2005-12-16 23:13:57 +00001319- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001320
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001321- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001322
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001323- A new AST parser implementation was completed. The abstract
1324 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001325 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001326
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001327- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001328 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1329
Neal Norwitz708e51a2005-10-03 04:48:15 +00001330- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1331
Neal Norwitz11bd1192005-10-03 00:54:56 +00001332- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1333 Provide a warning when a directory is passed on the command line.
1334
Neal Norwitz40d37812005-10-02 01:48:49 +00001335- Fix segfault with invalid coding.
1336
1337- SF bug #772896: unknown encoding results in MemoryError.
1338
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001339- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001340 supported a __len__() method which evaluated to False when the iterator
1341 was empty.
1342
Guido van Rossum630db602005-09-20 18:49:54 +00001343- On 64-bit platforms, when __len__() returns a value that cannot be
1344 represented as a C int, raise OverflowError.
1345
Skip Montanarof8948ca2005-09-19 03:54:46 +00001346- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001347 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001348
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001349- SF bug #893549: parsing keyword arguments was broken with a few format
1350 codes.
1351
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001352- Changes donated by Elemental Security to make it work on AIX 5.3
1353 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1354 bug #105470: test_pwd fails on 64bit system (Opteron).
1355
Guido van Rossum539c6622005-09-14 17:49:54 +00001356- Changes donated by Elemental Security to make it work on HP-UX 11 on
1357 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1358
Georg Brandl4550b8d2005-08-26 06:43:52 +00001359- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001360 (fixes bug #1119418).
1361
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001362- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1363
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001364- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1365 exceptions that cause a function to exit.
1366
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001367- The implementation of set() and frozenset() was revised to use its
1368 own internal data structure. Memory consumption is reduced by 1/3
1369 and there are modest speed-ups as well. The API is unchanged.
1370
Tim Petersde7990b2005-07-17 23:45:23 +00001371- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1372
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001373- SF bug #1229429: PyObject_CallMethod failed to decrement some
1374 reference counts in some error exit cases.
1375
Tim Petersecc6e6a2005-07-10 22:30:55 +00001376- SF bug #1185883: Python's small-object memory allocator took over
1377 a block managed by the platform C library whenever a realloc specified
1378 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001379 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001380 portable way to copy data from the C-managed block into Python's
1381 small-object space without risking a memory fault. Python's small-object
1382 realloc now leaves such blocks under the control of the platform C
1383 realloc.
1384
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001385- SF bug #1232517: An overflow error was not detected properly when
1386 attempting to convert a large float to an int in os.utime().
1387
Raymond Hettinger3296e692005-06-29 23:29:56 +00001388- SF bug #1224347: hex longs now print with lowercase letters just
1389 like their int counterparts.
1390
Michael W. Hudson188d4362005-06-20 16:52:57 +00001391- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1392 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1393 interpreter states; back out that fix and do a better job (see
1394 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1395 for a longer write-up of the problem).
1396
Michael W. Hudsondf888462005-06-03 14:41:55 +00001397- SF patch #1180995: marshal now uses a binary format by default when
1398 serializing floats.
1399
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001400- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1401 the routines that promise to produce IEEE 754 binary representations
1402 of floats now simply copy bytes around.
1403
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001404- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1405 278.
1406
Brett Cannonc3647ac2005-04-26 03:45:26 +00001407- patch #1109424: int, long, float, complex, and unicode now check for the
1408 proper magic slot for type conversions when subclassed. Previously the
1409 magic slot was ignored during conversion. Semantics now match the way
1410 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001411 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001412 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001413 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001414
Barry Warsawc8d907c2005-04-19 23:43:40 +00001415- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1416 NULL, now raise an AttributeError when attempting to set or delete the
1417 attribute. Previously a TypeError was raised, but this was inconsistent
1418 with the equivalent pure-Python implementation.
1419
Michael W. Hudson774479c2005-04-18 08:46:17 +00001420- It is now safe to call PyGILState_Release() before
1421 PyEval_InitThreads() (note that if there is reason to believe there
1422 are multiple threads around you still must call PyEval_InitThreads()
1423 before using the Python API; this fix is for extension modules that
1424 have no way of knowing if Python is multi-threaded yet).
1425
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001426- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1427 disabled caused a crash.
1428
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001429- Bug #1165306: instancemethod_new allowed the creation of a method
1430 with im_class == im_self == NULL, which caused a crash when called.
1431
Tim Petersecc6e6a2005-07-10 22:30:55 +00001432- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001433 fixes the crash seen in bug #1165761
1434
Raymond Hettinger96229b12005-03-11 06:49:40 +00001435- Added two new builtins, any() and all().
1436
Brett Cannon409d8f22005-03-05 06:47:57 +00001437- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001438 (e.g., ``class C(): pass`` is no longer a syntax error).
1439 Patch #1176012 added support to the 'parser' module and 'compiler' package
1440 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001441
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001442- Patch #1115086: Support PY_LONGLONG in structmember.
1443
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001444- Bug #1155938: new style classes did not check that __init__() was
1445 returning None.
1446
Tim Petersecc6e6a2005-07-10 22:30:55 +00001447- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001448 ('\') with a specific error message.
1449
Martin v. Löwisff232d72005-03-03 09:24:38 +00001450- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1451
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001452- Bug #1124295: the __name__ attribute of file objects was
1453 inadvertently made inaccessible in restricted mode.
1454
Tim Petersecc6e6a2005-07-10 22:30:55 +00001455- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001456 an ferror() call.
1457
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001458- min() and max() now support key= arguments with the same meaning as in
1459 list.sort().
1460
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001461- The peephole optimizer now performs simple constant folding in expressions:
1462 (2+3) --> (5).
1463
Raymond Hettingera422c342005-01-11 03:03:27 +00001464- set and frozenset objects can now be marshalled. SF #1098985.
1465
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001466- Bug #1077106: Poor argument checking could cause memory corruption
1467 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001468
Jeremy Hyltonab630502005-02-04 18:44:06 +00001469- The parser did not complain about future statements in illegal
1470 positions. It once again reports a syntax error if a future
1471 statement occurs after anything other than a doc string.
1472
Neil Schemenauercf52c072005-08-12 17:34:58 +00001473- Change the %s format specifier for str objects so that it returns a
1474 unicode instance if the argument is not an instance of basestring and
1475 calling __str__ on the argument returns a unicode instance.
1476
Tim Petersf4e69282006-02-27 17:15:31 +00001477- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1478 current thread state when the auto-GIL-state machinery knows about
1479 it (since the thread state is being deleted, continuing to remember it
1480 can't help, but can hurt if another thread happens to get created with
1481 the same thread id).

1674 been renamed to have only a single underscore prefix. This was done to
1675 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001676
Nick Coghlan43832302006-04-23 17:04:07 +00001677- PEP 338: new module runpy defines a run_module function to support
1678 executing modules which provide access to source code or a code object
1679 via the PEP 302 import mechanisms.
1680

1689 in attribute values.
1690
Anthony Baxterc51ee692006-04-01 00:57:31 +00001691- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001692 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001693 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001694 module will not be built.
1695
Tim Petersc17976e2006-04-01 00:26:53 +00001696- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1697 aren't officially supported here, and trying to use them will probably
1698 raise an exception some day. But dicts have been allowed, and "mostly
1699 worked", so support for them won't go away without warning.
1700
Georg Brandl338ef7d2006-03-31 18:42:16 +00001701- Bug #1445068: getpass.getpass() can now be given an explicit stream
1702 argument to specify where to write the prompt.
1703
Georg Brandl22ec80b2006-03-31 18:25:44 +00001704- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1719
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001720- email 4.0 package now integrated. This is largely the same as the email 3.0
1721 package that was included in Python 2.3, except that PEP 8 module names are
1722 now used (e.g. mail.message instead of email.Message). The MIME classes
1723 have been moved to a subpackage (e.g. email.mime.text instead of
1724 email.MIMEText). The old names are still supported for now. Several
1725 deprecated Message methods have been removed and lots of bugs have been
1726 fixed. More details can be found in the email package documentation.
1727
Walter Dörwald40108c92006-03-27 08:15:44 +00001728- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1729 (a subclass of tuple) that provides incremental decoders and encoders
1730 (a way to use stateful codecs without the stream API). Python functions
1731 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1732 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1733 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001734
Walter Dörwald067db482006-03-15 22:17:27 +00001735- Patch #1359365: Calling next() on a closed StringIO.String object raises
1736 a ValueError instead of a StopIteration now (like file and cString.String do).
1737 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1738 called before (like file and StringIO.StringIO do).

Martin v. Löwis04824ce2006-03-10 21:26:16 +00001740- A regrtest option -w was added to re-run failed tests in verbose mode.

1746 grew an optional 'generation' argument.
1747
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00001748- A library msilib to generate Windows Installer files, and a distutils

1819 is that SHA-256 is a good choice for the time being, but
1820 that research should continue, and other alternatives may
1821 arise from this research. The larger SHA's also seem OK."

2007 reporting.
2008 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2009 dictates.
2010 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002011 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002012 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002013 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2014 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002015 + reader now allows \r characters to be quoted (previously it only allowed
2016 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002017 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002018 + Dialect classes passed to the module are no longer instantiated by
2019 the module before being parsed (the former validation scheme required
2020 this, but the mechanism was unreliable).
2021 + The dialect registry now contains instances of the internal
2022 C-coded dialect type, rather than references to python objects.
2023 + the internal c-coded dialect type is now immutable.
2024 + register_dialect now accepts the same keyword dialect specifications
2025 as the reader and writer, allowing the user to register dialects
2026 without first creating a dialect class.
2027 + a configurable limit to the size of parsed fields has been added -
2028 previously, an unmatched quote character could result in the entire
2029 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002030 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002031 the parser field size limit (returning the former limit). The initial
2032 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002033 + A line_num attribute has been added to the reader object, which tracks
2034 the number of lines read from the source iterator. This is not
2035 the same as the number of records returned, as records can span
2036 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002037 + reader and writer objects were not being registered with the cyclic-GC.
2038 This has been fixed.
2039
Brett Cannone6539c42005-01-08 02:43:53 +00002040- _DummyThread objects in the threading module now delete self.__block that is
2041 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2042 lock primitives tend to be limited in number and thus should not be wasted on
2043 a _DummyThread object. Fixes bug #1089632.
2044
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002045- The imghdr module now detects Exif files.
2046
Raymond Hettinger6065d322004-12-20 23:51:53 +00002047- StringIO.truncate() now correctly adjusts the size attribute.
2048 (Bug #951915).
2049
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002050- locale.py now uses an updated locale alias table (built using
2051 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2052 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002053 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002054
Raymond Hettinger3557f422004-12-07 12:02:02 +00002055- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2056
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002057- the pickle module no longer accepts the deprecated None option in the
2058 args tuple returned by __reduce__().
2059
Brett Cannon84667c02004-12-07 03:25:18 +00002060- optparse now optionally imports gettext. This allows its use in setup.py.
2061
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002062- the pickle module no longer uses the deprecated bin parameter.
2063
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002064- the shelve module no longer uses the deprecated binary parameter.
2065

2067
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002068- the filecmp module no longer uses the deprecated use_statcache argument.
2069
Raymond Hettinger664347b2004-12-04 21:21:53 +00002070- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2071 extended or overridden by subclasses. Formerly, the subclassed method would
2072 be ignored by the rest of the module. (Bug #1078905).
2073
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002074- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002075 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002076
Walter Dörwald36733692004-12-22 12:50:50 +00002077- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2078 once when a size argument is given. This prevents a buffer overflow in the
2079 tokenizer with very long source lines.
2080
Barry Warsaw538561e2006-01-01 21:48:54 +00002081- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2082 immediately after creating the object, without any intervening
2083 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002084
Skip Montanaro05885812005-01-16 20:48:27 +00002085- The reconvert.quote function can now emit triple-quoted strings. The
2086 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002087
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002088- ``UserString.MutableString`` now supports negative indices in
2089 ``__setitem__`` and ``__delitem__``
2090
Greg Ward40407942005-03-05 02:53:17 +00002091- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2092 correctly.
2093
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002094- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2095 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2096 character even if the user has passed a size parameter to get a proper
2097 line ending. Remove the special handling of a "\r\n" that has been split
2098 between two lines.
2099
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002100- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2101 about illegal code points. The codec now supports PEP 293 style error
2102 handlers.
2103
Walter Dörwald78a78b02005-09-01 12:04:29 +00002104- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002105 from the input stream, so that the output is a byte string in the correct
2106 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002107
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002108- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2109 considering it exactly like a '*'.
2110
Walter Dörwald007f8df2005-10-09 19:42:27 +00002111- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2112 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002113
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002114- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2115
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002116- Patch #1413711: Certain patterns of differences were making difflib
2117 touch the recursion limit.
2118
Walter Dörwald58917a62006-03-31 15:26:22 +00002119- Bug #947906: An object oriented interface has been added to the calendar
2120 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002121 called as a script (e.g. via ``python -mcalendar``). Localized month and
2122 weekday names can be ouput (even if an exotic encoding is used) using
2123 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002124

2127
Neal Norwitz602d3392006-03-31 08:21:40 +00002128- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2129 by using -mieee gcc option.
2130

2132
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002133- Build support for Win64-AMD64 was added.
2134
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002135- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2136
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002137- Patch #881820: look for openpty and forkpty also in libbsd.
2138
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002139- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2140 The zlib module is now builtin on Windows.
2141
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002142- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2143
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002144- Bug #1189330: configure did not correctly determine the necessary
2145 value of LINKCC if python was built with GCC 4.0.
2146
Trent Mick8321b422005-07-26 02:29:21 +00002147- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2148 vulnerability in zlib 1.2.1 and 1.2.2.
2149
Brett Cannon08cd5982005-04-24 22:26:38 +00002150- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2151 flags that change binary compatibility. Changes were also made to
2152 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002153 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002154
Bob Ippolitoed233462005-03-29 13:47:59 +00002155- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2156 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2157 no longer exists). This configure patch makes things right.
2158
Martin v. Löwise2713be2005-03-08 15:03:08 +00002159- Bug #1158607: Build with --disable-unicode again.
2160
Brett Cannon46d96232005-02-16 00:07:19 +00002161- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2162 defined. Discovered as a result of not being able to build on OS X.
2163
Brett Cannon516592f2004-12-07 00:42:59 +00002164- setup.py now uses the directories specified in LDFLAGS using the -L option
2165 and in CPPFLAGS using the -I option for adding library and include
2166 directories, respectively, for compiling extension modules against. This has
2167 led to the core being compiled using the values in CPPFLAGS. It also removes
2168 the need for the special-casing of both DarwinPorts and Fink for darwin since
2169 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2170 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2171 Fink, ``-I/opt/local/include`` for DarwinPorts).
2172
Brett Cannon43802422005-02-10 20:48:03 +00002173- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2174 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2175 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2176 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002178C API
2179-----
2180
Tim Petersc9d78aa2006-03-26 23:27:58 +00002181- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2182 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2183 is obtained via the ``PyObject_`` family, it must be released via the
2184 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2185 always been officially true, but when Python's small-object allocator was
2186 introduced, an attempt was made to cater to a few extension modules
2187 discovered at the time that obtained memory via ``PyObject_New`` but
2188 released it via ``PyMem_DEL``. It's years later, and if such code still
2189 exists it will fail now (probably with segfaults, but calling wrong
2190 low-level memory management functions can yield many symptoms).
2191
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002192- Added a C API for set and frozenset objects.
2193
Raymond Hettinger66517482004-12-03 11:45:13 +00002194- Removed PyRange_New().
2195
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002196- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2197 mapping argument now. This string is used as a mapping table. Byte values
2198 greater than the length of the string and 0xFFFE are treated as undefined
2199 mappings.
