Georg Brandl1f215782006-09-24 10:36:08 +0000104- Make webbrowser.BackgroundBrowser usable in Windows (it wasn't because

133
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000134- Make _PyGILState_NoteThreadState() static, it was not used anywhere
135 outside of pystate.c and should not be necessary.
136
Brett Cannon19d76c52006-09-09 07:18:44 +0000137- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
138 allows calling unicode() on exceptions classes directly to succeed.
139
Georg Brandlecab6232006-09-06 06:47:02 +0000140- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

156 head is the original string if sep was not found.
157
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000158- Bug #1520864: unpacking singleton tuples in list comprehensions and
159 generator expressions (x for x, in ... ) works again. Fixing this problem
160 required changing the .pyc magic number. This means that .pyc files
161 generated before 2.5c2 will be regenerated.

259Core and builtins
260-----------------
261
Neal Norwitz24b6f202006-09-05 04:43:56 +0000262- Fix infinite recursion when subclassing long and overriding __hash__.
263
264- Fix concatenation (+=) of long strings.
265
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000266- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000267 compared equal or unequal to a string and a UnicodeDecodeError
268 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000269
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000270 Instead, the equal (==) and unequal (!=) comparison operators will
271 now issue a UnicodeWarning and interpret the two objects as
272 unequal. The UnicodeWarning can be filtered as desired using
273 the warning framework, e.g. silenced completely, turned into an
274 exception, logged, etc.
275
276 Note that compare operators other than equal and unequal will still
277 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000278
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000279- Fix segfault when doing string formatting on subclasses of long.
280
281- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines

283
284- Fix bug related to __len__ functions returning negative values with
285 classic classes.
286
287- Patch #1538606, Fix __index__() clipping. There were some problems
288 discovered with the API and how integers that didn't fit into Py_ssize_t
289 were handled. This patch attempts to provide enough alternatives
290 to effectively use __index__.
291
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000292- Bug #1536021: __hash__ may now return long int; the final hash
293 value is obtained by invoking hash on the long int.
294
Thomas Hellerab1049c2006-08-08 17:37:00 +0000295- Bug #1536786: buffer comparison could emit a RuntimeWarning.

301 the Python dll again.
302
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000303- Bug #1191458: tracing over for loops now produces a line event
304 on each iteration. Fixing this problem required changing the .pyc
305 magic number. This means that .pyc files generated before 2.5c1
306 will be regenerated.
307
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000308- Bug #1333982: string/number constants were inappropriately stored
309 in the byte code and co_consts even if they were not used, ie
310 immediately popped off the stack.

320
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000321- The distutils version has been changed to 2.5.0. The change to
322 keep it programmatically in sync with the Python version running
323 the code (introduced in 2.5b3) has been reverted. It will continue
324 to be maintained manually as static string literal.

Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000326- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000327 and this cannot be converted to the required C type, an exception is
328 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000329 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000330
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000331- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000332 an exception.
333
Tim Peterscbdd3502006-09-05 01:47:53 +0000334- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000335 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000336 workarounds for clocks with low resolution, to stop the code yielding
337 duplicate UUIDs.
338
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000339- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
340 before raising SystemExit, allowing IDLE to honor quit() and exit().
341
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000342- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
343
Georg Brandl7a1af772006-08-14 21:55:28 +0000344- Patch #1536071: trace.py should now find the full module name of a
345 file correctly even on Windows.
346
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000347- logging's atexit hook now runs even if the rest of the module has
348 already been cleaned up.
349
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000350- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000351
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000352- Bug #1531405, format_exception no longer raises an exception if
353 str(exception) raised an exception.
354
Neil Schemenauer06ded092006-08-04 16:20:30 +0000355- Fix a bug in the ``compiler`` package that caused invalid code to be
356 generated for nested functions.

367 raises the correct exceptions.
368
Thomas Heller1ce433e2006-08-14 16:20:04 +0000369- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
370 '-no-stack-protector' compiler flag for OpenBSD has been removed.
371
Thomas Heller86720042006-08-14 11:17:48 +0000372- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
373 uses the _as_parameter_ attribute when objects are passed to foreign
374 function calls. The ctypes version number was changed to 1.0.1.
375
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000376- Bug #1530559, struct.pack raises TypeError where it used to convert.
377 Passing float arguments to struct.pack when integers are expected
378 now triggers a DeprecationWarning.

416
Tim Peters4643c2f2006-08-10 22:45:34 +0000417- Bug #1069160. Internal correctness changes were made to
418 ``PyThreadState_SetAsyncExc()``. A test case was added, and
419 the documentation was changed to state that the return value
420 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000423What's New in Python 2.5 beta 3?
424================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000425
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000426*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000427
428Core and builtins
429-----------------
430
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000431- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000432 returned a long (see PEP 353).
433
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000434- Bug #1515471: string.replace() accepts character buffers again.
435
Neal Norwitz07aadb12006-07-30 06:55:48 +0000436- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
437 This provides the proper warning for struct.pack().
438 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
439
Neal Norwitz0d62a062006-07-30 06:53:31 +0000440- Patch #1531113: Fix augmented assignment with yield expressions.
441 Also fix a SystemError when trying to assign to yield expressions.
442
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000443- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
444 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
445 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
446 excessive filesystem operations during imports.
447
Tim Petersbc24eee2006-07-27 01:14:53 +0000448- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
449 operations on signed longs that are formally undefined by C.
450 Unfortunately, at least one compiler now cares about that, so complicated
451 the code to make that compiler happy again.
452
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000453- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
454
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000455- Patch #1232023: Stop including current directory in search
456 path on Windows.
457
Neal Norwitze1fdb322006-07-21 05:32:28 +0000458- Fix some potential crashes found with failmalloc.
459
Neal Norwitze7563102006-07-17 01:00:16 +0000460- Fix warnings reported by Klocwork's static analysis tool.
461
Neal Norwitz84be93b2006-07-16 01:50:38 +0000462- Bug #1512814, Fix incorrect lineno's when code within a function
463 had more than 255 blank lines.
464
Georg Brandl9dceedb2006-07-12 15:31:17 +0000465- Patch #1521179: Python now accepts the standard options ``--help`` and
466 ``--version`` as well as ``/?`` on Windows.
467
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000468- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000469 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000470 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000471
Tim Peters112aad32006-07-19 00:03:19 +0000472- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000473 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000474 new ``sys._current_frames()`` returns a dictionary with one entry,
475 mapping the faux "thread id" 0 to the current frame.
476
Ronald Oussoren3075e162006-07-25 20:28:55 +0000477- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000478

Neal Norwitza1f10902006-07-12 07:28:29 +0000480Library
481-------
482
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000483- Correction of patch #1455898: In the mbcs decoder, set final=False
484 for stream decoder, but final=True for the decode function.
485
Georg Brandl07fec3a2006-08-01 18:49:24 +0000486- os.urandom no longer masks unrelated exceptions like SystemExit or
487 KeyboardInterrupt.
488
Tim Peters4643c2f2006-08-10 22:45:34 +0000489- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000490 shutil.copytree on Windows
491
Georg Brandle34ac7c2006-07-30 11:07:23 +0000492- Bug #1002398: The documentation for os.path.sameopenfile now correctly
493 refers to file descriptors, not file objects.
494
Tim Peterscbdd3502006-09-05 01:47:53 +0000495- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000496 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000497 #1513611, and probably others.
498
Georg Brandledd9b0d2006-07-29 09:33:26 +0000499- Bug #1441397: The compiler module now recognizes module and function
500 docstrings correctly as it did in Python 2.4.
501
Tim Peters6f681472006-07-27 23:44:37 +0000502- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
503 lost that tests are sorted by name before being run. This rarely
504 matters for well-written tests, but can create baffling symptoms if
505 side effects from one test to the next affect outcomes. ``DocTestFinder``
506 has been changed to sort the list of tests it returns.
507
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000508- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000509 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000510
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000511- Bug #978833: Really close underlying socket in _socketobject.close.
512
Georg Brandldb232dc2006-08-20 13:15:43 +0000513- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
514 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000515
Georg Brandlcf0c1722006-07-26 07:23:32 +0000516- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
517 to recursive calls and call it with the failing package name.
518
Martin v. Löwis0b483032006-07-25 09:53:12 +0000519- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
520
Georg Brandlc13c34c2006-07-24 14:09:56 +0000521- Patch #1515343: Fix printing of deprecated string exceptions with a
522 value in the traceback module.
523
Greg Ward48fae7a2006-07-23 16:05:51 +0000524- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
525
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000526- Patch #1524429: Use repr() instead of backticks in Tkinter again.
527
Brett Cannoncaebe222006-07-18 04:41:36 +0000528- Bug #1520914: Change time.strftime() to accept a zero for any position in its
529 argument tuple. For arguments where zero is illegal, the value is forced to
530 the minimum value that is correct. This is to support an undocumented but
531 common way people used to fill in inconsequential information in the time
532 tuple pre-2.4.
533
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000534- Patch #1220874: Update the binhex module for Mach-O.
535
Barry Warsawb110bad2006-07-21 14:51:07 +0000536- The email package has improved RFC 2231 support, specifically for
537 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
538 (name*0=<blah>) parameter continuations. This may change the types of
539 values returned from email.message.Message.get_param() and friends.
540 Specifically in some cases where non-encoded continuations were used,
541 get_param() used to return a 3-tuple of (None, None, string) whereas now it
542 will just return the string (since non-encoded continuations don't have
543 charset and language parts).
544
545 Also, whereas % values were decoded in all parameter continuations, they are
546 now only decoded in encoded parameter parts.
547
Ronald Oussoren3075e162006-07-25 20:28:55 +0000548- Bug #1517990: IDLE keybindings on MacOS X now work correctly
549
550- Bug #1517996: IDLE now longer shows the default Tk menu when a
551 path browser, class browser or debugger is the frontmost window on MacOS X
552
Barry Warsaw00decd72006-07-27 23:43:15 +0000553- Patch #1520294: Support for getset and member descriptors in types.py,
554 inspect.py, and pydoc.py. Specifically, this allows for querying the type
555 of an object against these built-in types and more importantly, for getting
556 their docstrings printed in the interactive interpreter's help() function.

561
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000562- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
563 a socket operation on a socket with a timeout, the exception will be
564 caught correctly. Previously, the exception was not caught.
565
Thomas Heller1393d6a2006-07-28 21:43:20 +0000566- Patch #1529514: The _ctypes extension is now compiled on more
567 openbsd target platforms.
568
Tim Peters9cab5932006-07-28 00:30:00 +0000569- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
570 a memory leak, affecting pickles and deep copies.
571
Tim Petersbc24eee2006-07-27 01:14:53 +0000572- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

576
Thomas Hellerce049a02006-07-14 17:51:14 +0000577- Patch #1521817: Index range checking on ctypes arrays containing
578 exactly one element enabled again. This allows iterating over these
579 arrays, without the need to check the array size before.
580
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000581- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000582 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000583 /dev/null in certain cases; this is now fixed.
584
Thomas Heller47d7a062006-07-12 08:43:47 +0000585- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
586 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000587
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000588- Because of a misspelled preprocessor symbol, ctypes was always
589 compiled without thread support; this is now fixed.
590
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000591- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
592 methods now allow their database parameter to be None as the
593 sleepycat API allows.
594
Matt Flemingec926502006-07-28 11:27:27 +0000595- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
596 bluetooth API compared with Linux and FreeBSD.

600
601- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
602 how long the test file should take to play. Now accepts taking 2.93 secs
603 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
604
Georg Brandl4793aa32006-07-28 18:31:39 +0000605- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
606 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
607 run via ``regrtest.py``. Now they do.

617- PythonLauncher now works correctly when the path to the script contains
618 characters that are treated specially by the shell (such as quotes).
619
620- Bug #1527397: PythonLauncher now launches scripts with the working directory
621 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000622 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000623 expect.

631Core and builtins
632-----------------
633
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000634- Bug #1441486: The literal representation of -(sys.maxint - 1)
635 again evaluates to a int object, not a long.
636
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000637- Bug #1501934: The scope of global variables that are locally assigned
638 using augmented assignment is now correctly determined.
639
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000640- Bug #927248: Recursive method-wrapper objects can now safely
641 be released.
642
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000643- Bug #1417699: Reject locale-specific decimal point in float()
644 and atof().
645
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000646- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
647 omit a default "error" argument for NULL pointer. This allows
648 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000649
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000650- Bug #1519018: 'as' is now validated properly in import statements.
651
Neal Norwitz28746ab2006-07-09 22:14:42 +0000652- On 64 bit systems, int literals that use less than 64 bits are
653 now ints rather than longs.
654
Neal Norwitzed657552006-07-10 00:04:44 +0000655- Bug #1512814, Fix incorrect lineno's when code at module scope
656 started after line 256.
657
Tim Peters32a83612006-07-10 21:08:24 +0000658- New function ``sys._current_frames()`` returns a dict mapping thread
659 id to topmost thread stack frame. This is for expert use, and is
660 especially useful for debugging application deadlocks. The functionality
661 was previously available in Fazal Majid's ``threadframe`` extension
662 module, but it wasn't possible to do this in a wholly threadsafe way from
663 an extension.

672
Tim Peters32a83612006-07-10 21:08:24 +0000673- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000674 environment variable to be set in order to the SDK environment
675 for finding the compiler, include files, etc.
676

680
Thomas Woutersadd19112006-07-05 11:03:49 +0000681- string.Template() now correctly handles tuple-values. Previously,
682 multi-value tuples would raise an exception and single-value tuples would
683 be treated as the value they contain, instead.
684
Martin v. Löwisede77f52006-07-03 13:01:35 +0000685- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
686 even if some data are received.

692 degrees and radians.
693
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000694- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000695 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000696
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000697- Bug #1514703: Only setup canvas window in turtle when the canvas
698 is created.
699
Martin v. Löwis7596e832006-07-01 15:33:37 +0000700- Bug #1513223: .close() of a _socketobj now releases the underlying
701 socket again, which then gets closed as it becomes unreferenced.
702
Fred Drake10497c82006-06-29 02:57:48 +0000703- Bug #1504333: Make sgmllib support angle brackets in quoted
704 attribute values.
705
706- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
707 sgmllib ('[' and ']' were not accepted).
708
Georg Brandl1be63af2006-06-28 20:23:25 +0000709- Fix a bug in the turtle module's end_fill function.
710
Brett Cannon53ab5b72006-06-22 16:49:14 +0000711- Bug #1510580: The 'warnings' module improperly required that a Warning
712 category be either a types.ClassType and a subclass of Warning. The proper
713 check is just that it is a subclass with Warning as the documentation states.
714
Georg Brandlad29e632006-06-21 17:45:17 +0000715- The compiler module now correctly compiles the new try-except-finally
716 statement (bug #1509132).
717
Neal Norwitz60373cd2006-06-22 06:30:50 +0000718- The wsgiref package is now installed properly on Unix.
719
Vinay Sajip28e57612006-07-01 10:45:20 +0000720- A bug was fixed in logging.config.fileConfig() which caused a crash on
721 shutdown when fileConfig() was called multiple times.
722
Gerhard Häring762fbd32006-07-02 17:48:30 +0000723- The sqlite3 module did cut off data from the SQLite database at the first
724 null character before sending it to a custom converter. This has been fixed
725 now.
726
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000727Extension Modules
728-----------------
729
Tim Peters112aad32006-07-19 00:03:19 +0000730- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
731 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
732 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000733
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000734- Assigning None to pointer type fields in ctypes structures possible
735 overwrote the wrong fields, this is fixed now.
736
737- Fixed a segfault in _ctypes when ctypes.wintypes were imported
738 on non-Windows platforms.
739
740- Bug #1518190: The ctypes.c_void_p constructor now accepts any
741 integer or long, without range checking.
742
743- Patch #1517790: It is now possible to use custom objects in the ctypes
744 foreign function argtypes sequence as long as they provide a from_param
745 method, no longer is it required that the object is a ctypes type.
746
747- The '_ctypes' extension module now works when Python is configured
748 with the --without-threads option.
749
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000750- Bug #1513646: os.access on Windows now correctly determines write
751 access, again.
752
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000753- Bug #1512695: cPickle.loads could crash if it was interrupted with
754 a KeyboardInterrupt.
755
Neal Norwitza12aa882006-07-06 06:45:08 +0000756- Bug #1296433: parsing XML with a non-default encoding and
757 a CharacterDataHandler could crash the interpreter in pyexpat.

762-----
763
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000764- Automate Windows build process for the Win64 SSL module.
765
Tim Peters32a83612006-07-10 21:08:24 +0000766- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000767 Previously, the slight difference could cause compilation errors of the
768 'zlib' module on systems with more than one version of zlib.
769
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000770- The MSI compileall step was fixed to also support a TARGETDIR
771 with spaces in it.
772
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000773- Bug #1517388: sqlite3.dll is now installed on Windows independent
774 of Tcl/Tk.
775
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000776- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000777 trying to be installed even though it's empty.

780-----
781
782- Call os.waitpid() at the end of tests that spawn child processes in order
783 to minimize resources (zombies).
784
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000785Documentation
786-------------
787
Nick Coghlan2d792252006-07-06 13:47:18 +0000788- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
789 documentation for the warnings module.
790
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000791- Patch #1509163: MS Toolkit Compiler no longer available.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000800
801Core and builtins
802-----------------
803
Georg Brandla56b9152006-06-19 06:35:54 +0000804- Patch #1507676: Error messages returned by invalid abstract object operations
805 (such as iterating over an integer) have been improved and now include the
806 type of the offending object to help with debugging.
807
Brett Cannonea3912b2006-06-13 21:46:41 +0000808- Bug #992017: A classic class that defined a __coerce__() method that returned
809 its arguments swapped would infinitely recurse and segfault the interpreter.
810
Neal Norwitz909eb122006-06-12 02:13:21 +0000811- Fix the socket tests so they can be run concurrently.
812
Neal Norwitzb9845e72006-06-12 02:11:18 +0000813- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000814 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000815
Brett Cannon22565aa2006-06-09 22:31:23 +0000816- Bug #532646: object.__call__() will continue looking for the __call__
817 attribute on objects until one without one is found. This leads to recursion
818 when you take a class and set its __call__ attribute to an instance of the
819 class. Originally fixed for classic classes, but this fix is for new-style.
820 Removes the infinite_rec_3 crasher.
821
Georg Brandl24250812006-06-09 18:45:48 +0000822- The string and unicode methods startswith() and endswith() now accept
823 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
824
Brett Cannonde3b0522006-06-08 17:00:45 +0000825- Buffer objects, at the C level, never used the char buffer
826 implementation even when the char buffer for the wrapped object was
827 explicitly requested (originally returned the read or write buffer).
828 Now a TypeError is raised if the char buffer is not present but is
829 requested.
830
Georg Brandlddbaa662006-06-04 21:56:52 +0000831- Patch #1346214: Statements like "if 0: suite" are now again optimized
832 away like they were in Python 2.4.
833
Georg Brandlb7c8f542006-05-27 12:30:25 +0000834- Builtin exceptions are now full-blown new-style classes instead of
835 instances pretending to be classes, which speeds up exception handling
836 by about 80% in comparison to 2.5a2.
837
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000838- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
839 Unicode 4.1.
840
Georg Brandlf4ef1162006-05-26 18:03:31 +0000841- Patch #921466: sys.path_importer_cache is now used to cache valid and
842 invalid file paths for the built-in import machinery which leads to
843 fewer open calls on startup.
844
Tim Peters696cf432006-05-24 21:10:40 +0000845- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
846 of-2 bases. The largest speedup is for inputs with about 1000 decimal
847 digits. Conversion from non-power-of-2 bases remains quadratic-time in
848 the number of input digits (it was and remains linear-time for bases
849 2, 4, 8, 16 and 32).
850
Tim Petersb713ec22006-05-23 18:45:30 +0000851- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
852 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
853 an integer close to ``sys.maxint``. This was repaired by patch
854 #1335972, which also gives a nice speedup.
855
Richard Jonescebbefc2006-05-23 18:28:17 +0000856- Patch #1337051: reduced size of frame objects.
857
858- PyErr_NewException now accepts a tuple of base classes as its
859 "base" parameter.
860
Richard Jones7c88dcc2006-05-23 10:37:38 +0000861- Patch #876206: function call speedup by retaining allocated frame
862 objects.
863
Georg Brandl7b90e162006-05-18 07:01:27 +0000864- Bug #1462152: file() now checks more thoroughly for invalid mode
865 strings and removes a possible "U" before passing the mode to the
866 C library function.
867
Neal Norwitz1004a532006-05-15 07:17:23 +0000868- Patch #1488312, Fix memory alignment problem on SPARC in unicode
869
Neal Norwitz373f0a72006-05-15 07:04:36 +0000870- Bug #1487966: Fix SystemError with conditional expression in assignment
871
Martin v. Löwis879768d2006-05-11 13:28:43 +0000872- WindowsError now has two error code attributes: errno, which carries
873 the error values from errno.h, and winerror, which carries the error
874 values from winerror.h. Previous versions put the winerror.h values
875 (from GetLastError()) into the errno attribute.
876
Martin v. Löwis77736712006-05-04 05:51:03 +0000877- Patch #1475845: Raise IndentationError for unexpected indent.
878
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000879- Patch #1479181: split open() and file() from being aliases for each other.
880
Tim Peters44bd9862006-06-01 13:49:23 +0000881- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
882 methods were always silently ignored by dictionaries when comparing keys.
883 They are now passed through (except when using the C API function
884 ``PyDict_GetItem()``, whose semantics did not change).
885
886- Bug #1456209: In some obscure cases it was possible for a class with a
887 custom ``__eq__()`` method to confuse dict internals when class instances
888 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
889 No, you don't have any code that did this ;-)

895
896- Patch #1462338: Upgrade pyexpat to expat 2.0.0
897
Brett Cannon6ee7d012006-06-08 16:23:04 +0000898- Change binascii.hexlify to accept a read-only buffer instead of only a char
899 buffer and actually follow its documentation.
900

902
Nick Coghlanc649ec52006-05-29 12:43:05 +0000903- Patch #1478788 (modified version): The functional extension module has
904 been renamed to _functools and a functools Python wrapper module added.
905 This provides a home for additional function related utilities that are
906 not specifically about functional programming. See PEP 309.
907
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000908- Patch #1493701: performance enhancements for struct module.

917
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000918- On Win32, os.listdir now supports arbitrarily-long Unicode path names
919 (up to the system limit of 32K characters).
920
921- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
922 As a result, these functions now raise WindowsError instead of OSError.
923
Tim Peters7a822da2006-05-25 21:50:17 +0000924- ``time.clock()`` on Win64 should use the high-performance Windows
925 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
926 Windows platforms).
927
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000928- Calling Tk_Init twice is refused if the first call failed as that
929 may deadlock.
930
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000931- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
932 accept it without potentially using an uninitialized pointer.
933
934- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
935 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smith372b5832006-06-05 18:48:21 +0000941- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
942 parameter is supplied. [SF pybsddb bug #1477863]
943
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000944- bsddb: the __len__ method of a DB object has been fixed to return correct
945 results. It could previously incorrectly return 0 in some cases.
946 Fixes SF bug 1493322 (pybsddb bug 1184012).
947
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000948- bsddb: the bsddb.dbtables Modify method now raises the proper error and
949 aborts the db transaction safely when a modifier callback fails.
950 Fixes SF python patch/bug #1408584.
951
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000952- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000953 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000954 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
955 database calls that would previously deadlock. [SF python bug #775414]

989 non-adjacent blocks. Previously, a pair of matching blocks could end
990 up being described by multiple adjacent triples that formed a partition

1002
Nick Coghlan676725d2006-06-08 13:54:49 +00001003- The functions update_wrapper() and wraps() have been added to the functools
1004 module. These make it easier to copy relevant metadata from the original

Martin v. Löwis3f767792006-06-04 19:36:28 +00001010- Patch #1359618: Speed up charmap encoder by using a trie structure
1011 for lookup.
1012
Tim Petersd609b1a2006-06-02 23:22:51 +00001013- The functions in the ``pprint`` module now sort dictionaries by key
1014 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1015 if and only if its display required more than one line, although that
1016 wasn't documented. The new behavior increases predictability; e.g.,
1017 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.

1044 a couple of issues, notably handling of long file names using the
1045 GNU LONGNAME extension.
1046

1094Core and builtins
1095-----------------
1096
Thomas Heller1b046642006-04-18 18:51:06 +00001097- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1098 by converting these apis from macros into exported functions again:
1099
1100 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1101 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1102 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

1104 PyRun_String Py_CompileString
1105
Martin v. Löwis45294a92006-04-18 06:24:08 +00001106- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1107
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001108- All uses of PyStructSequence_InitType have been changed to initialize
1109 the type objects only once, even if the interpreter is initialized
1110 multiple times.
1111
Neal Norwitz61546162006-04-14 05:20:28 +00001112- Bug #1454485, array.array('u') could crash the interpreter. This was
1113 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1114 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1115
1116- Py_UNICODE is unsigned. It was always documented as unsigned, but
1117 due to a bug had a signed value in previous versions.
1118
Tim Peters3a5e8b12006-04-11 01:44:07 +00001119- Patch #837242: ``id()`` of any Python object always gives a positive
1120 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1121 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001122 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001123 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001124
Tim Peters3a5e8b12006-04-11 01:44:07 +00001125 def __hash__(self):
1126 return id(self) # WRONG
1127
1128 because a hash result must be a (short) Python int but it was always
1129 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001130 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001131 was always usable as a hash value before this patch. That's no longer
1132 necessarily so.
1133
1134- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001135 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001136 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001137 #1454844)
1138
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001139- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1140 involving generators that have paused outside of any ``try`` or ``with``
1141 blocks. (In 2.5a1, a paused generator that was part of a reference
1142 cycle could not be garbage collected, regardless of whether it was
1143 paused in a ``try`` or ``with`` block.)

1173 abusing errno.
1174
Tim Peters711bf302006-04-25 03:31:36 +00001175- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1176 a doctest to be skipped (the code is not run, and the expected output
1177 or exception is ignored).
1178
Nick Coghlanda2268f2006-04-24 04:37:15 +00001179- Fixed contextlib.nested to cope with exceptions being raised and
1180 caught inside exit handlers.
1181
Greg Wardab05edc2006-04-23 03:47:58 +00001182- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1183 hex, octal, or binary; add ``append_const`` action; keep going if
1184 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1185 added ``epilog`` for better help generation).
1186
Tim Peters21fbd572006-04-21 21:18:10 +00001187- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1188 called from a thread spawned as a side effect of importing a module.
1189
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001190- The pydoc module now supports documenting packages contained in
1191 .zip or .egg files.
1192
1193- The pkgutil module now has several new utility functions, such
1194 as ``walk_packages()`` to support working with packages that are either
1195 in the filesystem or zip files.
1196
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001197- The mailbox module can now modify and delete messages from
1198 mailboxes, in addition to simply reading them. Thanks to Gregory
1199 K. Johnson for writing the code, and to the 2005 Google Summer of
1200 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001201
Tim Petersc7605f22006-04-17 21:12:33 +00001202- The ``__del__`` method of class ``local`` in module ``_threading_local``
1203 returned before accomplishing any of its intended cleanup.
1204
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001205- Patch #790710: Add breakpoint command lists in pdb.

Martin v. Löwis4be4e652006-04-17 19:25:49 +00001231- The Makefile now has a reindent target, which runs reindent.py on
1232 the library.
1233
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001234- Patch #1470875: Building Python with MS Free Compiler
1235
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001236- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001237
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001238- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1239 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001240 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001241 CXX from --with-cxx-main, see description in README.
1242
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001243- Patch #1429775: Link extension modules with the shared libpython.
1244
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001245- Fixed a libffi build problem on MIPS systems.
1246
Tim Peters8931ff12006-05-13 23:28:20 +00001247- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1248 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1249 and "%zu" for unsigned integers of type ``size_t``.
1250
Anthony Baxter51bcb682006-04-05 14:51:42 +00001251Tests
1252-----
1253
Nick Coghlanda2268f2006-04-24 04:37:15 +00001254- test_contextlib now checks contextlib.nested can cope with exceptions
1255 being raised and caught inside exit handlers.
1256
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001257- test_cmd_line now checks operation of the -m and -c command switches
1258
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001259- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1260 it separately and by hand. It also wasn't cleaning up its changes to
1261 the current Decimal context.
1262
Thomas Woutersabd08882006-04-26 15:53:30 +00001263- regrtest.py now has a -M option to run tests that test the new limits of
1264 containers, on 64-bit architectures. Running these tests is only sensible
1265 on 64-bit machines with more than two gigabytes of memory. The argument
1266 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001274Documentation
1275-------------
1276
Tim Petersb06d28c2006-05-12 01:57:59 +00001277- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1278
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001279- PEP 343: Added Context Types section to the library reference
1280 and attempted to bring other PEP 343 related documentation into
1281 line with the implementation and/or python-dev discussions.
1282
Tim Peters8dc73d22006-04-24 02:03:16 +00001283- Bug #1337990: clarified that ``doctest`` does not support examples
1284 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001287What's New in Python 2.5 alpha 1?
1288=================================
1289
Anthony Baxterebed3f62006-04-03 15:03:44 +00001290*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001291
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001292Core and builtins
1293-----------------
1294
Nick Coghlan43832302006-04-23 17:04:07 +00001295- PEP 338: -m command line switch now delegates to runpy.run_module
1296 allowing it to support modules in packages and zipfiles
1297
Martin v. Löwisc661b882006-04-20 04:54:23 +00001298- On Windows, .DLL is not an accepted file name extension for
1299 extension modules anymore; extensions are only found if they
1300 end in .PYD.
1301
Martin v. Löwisea62d252006-04-03 10:56:49 +00001302- Bug #1421664: sys.stderr.encoding is now set to the same value as
1303 sys.stdout.encoding.
1304
Neal Norwitz92e212f2006-04-03 04:48:37 +00001305- __import__ accepts keyword arguments.
1306
Georg Brandlccadf842006-03-31 18:54:53 +00001307- Patch #1460496: round() now accepts keyword arguments.
1308
Anthony Baxter262c00a2006-03-30 10:53:17 +00001309- Fixed bug #1459029 - unicode reprs were double-escaped.
1310
Hye-Shik Changd478f342006-03-23 12:32:36 +00001311- Patch #1396919: The system scope threads are reenabled on FreeBSD
1312 5.4 and later versions.
1313
Neal Norwitze98ccf62006-03-23 05:39:47 +00001314- Bug #1115379: Compiling a Unicode string with an encoding declaration
1315 now gives a SyntaxError.
1316
Georg Brandlabd1ff82006-03-18 07:59:59 +00001317- Previously, Python code had no easy way to access the contents of a
1318 cell object. Now, a ``cell_contents`` attribute has been added
1319 (closes patch #1170323).
1320
Tim Peterscf79aac2006-03-16 01:14:46 +00001321- Patch #1123430: Python's small-object allocator now returns an arena to
1322 the system ``free()`` when all memory within an arena becomes unused
1323 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1324 freed. Some applications will see a drop in virtual memory size now,
1325 especially long-running applications that, from time to time, temporarily
1326 use a large number of small objects. Note that when Python returns an
1327 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001328 platform C library will in turn return that memory to the operating system.
1329 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001330 appears to be effective at least on Microsoft C and gcc-based systems.
1331 Thanks to Evan Jones for hard work and patience.
1332
Georg Brandl533ff6f2006-03-08 18:09:27 +00001333- Patch #1434038: property() now uses the getter's docstring if there is
1334 no "doc" argument given. This makes it possible to legitimately use
1335 property() as a decorator to produce a read-only property.
1336
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001337- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1338 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1339 of requiring an int or long in slicing and a few other contexts, enabling
1340 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1341
Neal Norwitz995acdf2006-03-07 05:01:00 +00001342- Fixed various bugs reported by Coverity's Prevent tool.
1343
Brett Cannonbf364092006-03-01 04:25:17 +00001344- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1345 new exception base class, BaseException, which has a new message attribute.
1346 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1347 Raising a string exception now raises a DeprecationWarning.
1348
Thomas Woutersfb609f42006-02-28 16:37:25 +00001349- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1350 explicitly relative, using 'from .module import name' to mean 'from the same
1351 package as this module is in. Imports without dots still default to the
1352 old relative-then-absolute, unless 'from __future__ import
1353 absolute_import' is used.
1354
Brett Cannona7446e32006-02-27 23:39:10 +00001355- Properly check if 'warnings' raises an exception (usually when a filter set
1356 to "error" is triggered) when raising a warning for raising string
1357 exceptions.
1358
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001359- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001360 The name was removed from Include/code.h.
1361
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001362- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001363
Guido van Rossum1968ad32006-02-25 22:38:04 +00001364- Patch 1433928:
1365 - The copy module now "copies" function objects (as atomic objects).
1366 - dict.__getitem__ now looks for a __missing__ hook before raising
1367 KeyError.
1368
Tim Peters84ef21c2006-02-28 20:39:06 +00001369- PEP 343: with statement implemented. Needs ``from __future__ import
1370 with_statement``. Use of 'with' as a variable will generate a warning.
1371 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001372 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001373 The following objects have __context__ methods:
1374 - The built-in file type.
1375 - The thread.LockType type.
1376 - The following types defined by the threading module:
1377 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1378 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001379
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001380- Fix the encodings package codec search function to only search
1381 inside its own package. Fixes problem reported in patch #1433198.
1382
1383 Note: Codec packages should implement and register their own
1384 codec search function. PEP 100 has the details.
1385
Tim Peters9ea89d22006-06-04 03:26:02 +00001386- PEP 353: Using ``Py_ssize_t`` as the index type.
1387
1388- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1389 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1390 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1391 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1392 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001393
Neal Norwitzfc76d632006-01-10 06:03:13 +00001394- Patch #1400181, fix unicode string formatting to not use the locale.
1395 This is how string objects work. u'%f' could use , instead of .
1396 for the decimal point. Now both strings and unicode always use periods.
1397
Neal Norwitz671b9e32006-01-09 07:07:12 +00001398- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1399 configure would break checking curses.h.
1400
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001401- Bug #959576: The pwd module is now builtin. This allows Python to be
1402 built on UNIX platforms without $HOME set.
1403
Neal Norwitzc10978f2005-12-19 06:07:16 +00001404- Bug #1072182, fix some potential problems if characters are signed.
1405
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001406- Bug #889500, fix line number on SyntaxWarning for global declarations.
1407
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001408- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1409
Neal Norwitze7214a12005-12-18 05:03:17 +00001410- Support for converting hex strings to floats no longer works.
1411 This was not portable. float('0x3') now raises a ValueError.
1412
Barry Warsaw2a38a862005-12-18 01:27:35 +00001413- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001414 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001415 is now displayed in interactive prompt banner.
1416
Georg Brandlfa166682005-12-17 21:45:17 +00001417- Implementation of PEP 341 - Unification of try/except and try/finally.
1418 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001419 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001420
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001421- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1422 now encodes backslash correctly.
1423
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001424- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1425
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001426- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001427 and long longs.
1428
Neal Norwitz67715f02005-11-09 06:59:35 +00001429- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001430 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001431 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001432
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001433- Replaced most Unicode charmap codecs with new ones using the
1434 new Unicode translate string feature in the builtin charmap
1435 codec; the codecs were created from the mapping tables available
1436 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1437 encodings now include a mapping for the Apple logo)
1438
Tim Peterse3547fd2005-12-16 23:13:57 +00001439- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001440
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001441- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001442
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001443- A new AST parser implementation was completed. The abstract
1444 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001445 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001446
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001447- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001448 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1449
Neal Norwitz708e51a2005-10-03 04:48:15 +00001450- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1451
Neal Norwitz11bd1192005-10-03 00:54:56 +00001452- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1453 Provide a warning when a directory is passed on the command line.
1454
Neal Norwitz40d37812005-10-02 01:48:49 +00001455- Fix segfault with invalid coding.
1456
1457- SF bug #772896: unknown encoding results in MemoryError.
1458
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001459- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001460 supported a __len__() method which evaluated to False when the iterator
1461 was empty.
1462
Guido van Rossum630db602005-09-20 18:49:54 +00001463- On 64-bit platforms, when __len__() returns a value that cannot be
1464 represented as a C int, raise OverflowError.
1465
Skip Montanarof8948ca2005-09-19 03:54:46 +00001466- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001467 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001468
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001469- SF bug #893549: parsing keyword arguments was broken with a few format
1470 codes.
1471
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001472- Changes donated by Elemental Security to make it work on AIX 5.3
1473 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1474 bug #105470: test_pwd fails on 64bit system (Opteron).
1475
Guido van Rossum539c6622005-09-14 17:49:54 +00001476- Changes donated by Elemental Security to make it work on HP-UX 11 on
1477 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1478
Georg Brandl4550b8d2005-08-26 06:43:52 +00001479- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001480 (fixes bug #1119418).
1481
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001482- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1483
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001484- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1485 exceptions that cause a function to exit.
1486
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001487- The implementation of set() and frozenset() was revised to use its
1488 own internal data structure. Memory consumption is reduced by 1/3
1489 and there are modest speed-ups as well. The API is unchanged.
1490
Tim Petersde7990b2005-07-17 23:45:23 +00001491- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1492
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001493- SF bug #1229429: PyObject_CallMethod failed to decrement some
1494 reference counts in some error exit cases.
1495
Tim Petersecc6e6a2005-07-10 22:30:55 +00001496- SF bug #1185883: Python's small-object memory allocator took over
1497 a block managed by the platform C library whenever a realloc specified
1498 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001499 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001500 portable way to copy data from the C-managed block into Python's
1501 small-object space without risking a memory fault. Python's small-object
1502 realloc now leaves such blocks under the control of the platform C
1503 realloc.

Michael W. Hudsonb8963812005-07-05 15:21:58 +00001505- SF bug #1232517: An overflow error was not detected properly when
1506 attempting to convert a large float to an int in os.utime().
1507
Raymond Hettinger3296e692005-06-29 23:29:56 +00001508- SF bug #1224347: hex longs now print with lowercase letters just
1509 like their int counterparts.
1510
Michael W. Hudson188d4362005-06-20 16:52:57 +00001511- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1512 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1513 interpreter states; back out that fix and do a better job (see
1514 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1515 for a longer write-up of the problem).
1516
Michael W. Hudsondf888462005-06-03 14:41:55 +00001517- SF patch #1180995: marshal now uses a binary format by default when
1518 serializing floats.
1519
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001520- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1521 the routines that promise to produce IEEE 754 binary representations
1522 of floats now simply copy bytes around.
1523
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001524- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1525 278.
1526
Brett Cannonc3647ac2005-04-26 03:45:26 +00001527- patch #1109424: int, long, float, complex, and unicode now check for the
1528 proper magic slot for type conversions when subclassed. Previously the
1529 magic slot was ignored during conversion. Semantics now match the way
1530 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001531 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001532 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001533 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001534
Barry Warsawc8d907c2005-04-19 23:43:40 +00001535- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1536 NULL, now raise an AttributeError when attempting to set or delete the
1537 attribute. Previously a TypeError was raised, but this was inconsistent
1538 with the equivalent pure-Python implementation.
1539
Michael W. Hudson774479c2005-04-18 08:46:17 +00001540- It is now safe to call PyGILState_Release() before
1541 PyEval_InitThreads() (note that if there is reason to believe there
1542 are multiple threads around you still must call PyEval_InitThreads()
1543 before using the Python API; this fix is for extension modules that
1544 have no way of knowing if Python is multi-threaded yet).
1545
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001546- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1547 disabled caused a crash.
1548
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001549- Bug #1165306: instancemethod_new allowed the creation of a method
1550 with im_class == im_self == NULL, which caused a crash when called.
1551
Tim Petersecc6e6a2005-07-10 22:30:55 +00001552- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001553 fixes the crash seen in bug #1165761
1554
Raymond Hettinger96229b12005-03-11 06:49:40 +00001555- Added two new builtins, any() and all().
1556
Brett Cannon409d8f22005-03-05 06:47:57 +00001557- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001558 (e.g., ``class C(): pass`` is no longer a syntax error).
1559 Patch #1176012 added support to the 'parser' module and 'compiler' package
1560 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001561
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001562- Patch #1115086: Support PY_LONGLONG in structmember.
1563
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001564- Bug #1155938: new style classes did not check that __init__() was
1565 returning None.
1566
Tim Petersecc6e6a2005-07-10 22:30:55 +00001567- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001568 ('\') with a specific error message.
1569
Martin v. Löwisff232d72005-03-03 09:24:38 +00001570- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1571
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001572- Bug #1124295: the __name__ attribute of file objects was
1573 inadvertently made inaccessible in restricted mode.
1574
Tim Petersecc6e6a2005-07-10 22:30:55 +00001575- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001576 an ferror() call.
1577
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001578- min() and max() now support key= arguments with the same meaning as in
1579 list.sort().
1580
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001581- The peephole optimizer now performs simple constant folding in expressions:
1582 (2+3) --> (5).
1583
Raymond Hettingera422c342005-01-11 03:03:27 +00001584- set and frozenset objects can now be marshalled. SF #1098985.
1585
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001586- Bug #1077106: Poor argument checking could cause memory corruption
1587 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001588
Jeremy Hyltonab630502005-02-04 18:44:06 +00001589- The parser did not complain about future statements in illegal
1590 positions. It once again reports a syntax error if a future
1591 statement occurs after anything other than a doc string.
1592
Neil Schemenauercf52c072005-08-12 17:34:58 +00001593- Change the %s format specifier for str objects so that it returns a
1594 unicode instance if the argument is not an instance of basestring and
1595 calling __str__ on the argument returns a unicode instance.
1596
Tim Petersf4e69282006-02-27 17:15:31 +00001597- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1598 current thread state when the auto-GIL-state machinery knows about
1599 it (since the thread state is being deleted, continuing to remember it
1600 can't help, but can hurt if another thread happens to get created with
1601 the same thread id).
1602
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001603Extension Modules
1604-----------------
1605

1620
1621- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1622
1623- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001624 is deprecated. The undocumented re.engine variable no longer exists.
1625

1628
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001629- The unicodedata module was updated to the 4.1 version of the Unicode
1630 database. The 3.2 version is still available as unicodedata.db_3_2_0
1631 for applications that require this specific version (such as IDNA).
1632
Neal Norwitzb62c4332006-03-04 18:35:47 +00001633- The timing module is no longer built by default. It was deprecated
1634 in PEP 4 in Python 2.0 or earlier.
1635
Guido van Rossum1968ad32006-02-25 22:38:04 +00001636- Patch 1433928: Added a new type, defaultdict, to the collections module.
1637 This uses the new __missing__ hook behavior added to dict (see above).
1638
Georg Brandldbd83392006-02-20 09:42:33 +00001639- Bug #854823: socketmodule now builds on Sun platforms even when

1654
Martin v. Löwis14694662006-02-03 12:54:16 +00001655- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1656 are reported, the limit on path name lengths is removed, and stat reports
1657 WindowsError now (instead of OSError).
1658
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001659- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

1734 the request code argument, which results in more C-like behaviour
1735 for large or negative values.
1736
Tim Petersecc6e6a2005-07-10 22:30:55 +00001737- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

1779
Raymond Hettingerb2594052004-12-05 09:25:51 +00001780- itertools.islice() now accepts None for the start and step arguments.

Tim Peters112aad32006-07-19 00:03:19 +00001792
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001793- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1794 been renamed to have only a single underscore prefix. This was done to
1795 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001796
Nick Coghlan43832302006-04-23 17:04:07 +00001797- PEP 338: new module runpy defines a run_module function to support
1798 executing modules which provide access to source code or a code object
1799 via the PEP 302 import mechanisms.
1800
Anthony Baxter93f5b932006-04-03 08:05:07 +00001801- The email module's parsedate_tz function now sets the daylight savings

1809 in attribute values.
1810
Anthony Baxterc51ee692006-04-01 00:57:31 +00001811- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001812 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001813 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001814 module will not be built.
1815
Tim Petersc17976e2006-04-01 00:26:53 +00001816- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1817 aren't officially supported here, and trying to use them will probably
1818 raise an exception some day. But dicts have been allowed, and "mostly
1819 worked", so support for them won't go away without warning.
1820
Georg Brandl338ef7d2006-03-31 18:42:16 +00001821- Bug #1445068: getpass.getpass() can now be given an explicit stream
1822 argument to specify where to write the prompt.
1823
Georg Brandl22ec80b2006-03-31 18:25:44 +00001824- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1833 to make it easier to monitor when daemon threads have completed
1834 processing all enqueued tasks. Patch #1455676.
1835
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001836- popen2.Popen objects now preserve the command in a .cmd attribute.

1839
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001840- email 4.0 package now integrated. This is largely the same as the email 3.0
1841 package that was included in Python 2.3, except that PEP 8 module names are
1842 now used (e.g. mail.message instead of email.Message). The MIME classes
1843 have been moved to a subpackage (e.g. email.mime.text instead of
1844 email.MIMEText). The old names are still supported for now. Several
1845 deprecated Message methods have been removed and lots of bugs have been
1846 fixed. More details can be found in the email package documentation.
1847
Walter Dörwald40108c92006-03-27 08:15:44 +00001848- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1849 (a subclass of tuple) that provides incremental decoders and encoders
1850 (a way to use stateful codecs without the stream API). Python functions
1851 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1852 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1853 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001854
Walter Dörwald067db482006-03-15 22:17:27 +00001855- Patch #1359365: Calling next() on a closed StringIO.String object raises
1856 a ValueError instead of a StopIteration now (like file and cString.String do).
1857 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1858 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001859
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001860- A regrtest option -w was added to re-run failed tests in verbose mode.

1933 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1934 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1935 Ronald L. Rivest offered this advice for Python:
1936
1937 "The consensus of researchers in this area (at least as
1938 expressed at the NIST Hash Function Workshop 10/31/05),
1939 is that SHA-256 is a good choice for the time being, but
1940 that research should continue, and other alternatives may
1941 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001942
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001943- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl5284b532005-06-26 22:54:58 +00002027
Georg Brandl2f210b62005-06-26 22:09:06 +00002028- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2029
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002030- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2031 error messages.
2032
Georg Brandl379f99d2005-06-26 21:09:38 +00002033- Bug #1108948: Cookie.py produced invalid JavaScript code.
2034
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002035- The tokenize module now detects and reports indentation errors.
2036 Bug #1224621.
2037
Raymond Hettinger68c04532005-06-10 11:05:19 +00002038- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002039 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002040 the generate_tokens() function now accepts a callable argument that
2041 terminates by raising StopIteration.
2042
Georg Brandl9166e1a2005-06-04 09:20:03 +00002043- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2044
Georg Brandl268e61c2005-06-03 14:28:50 +00002045- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2046 component of the path.
2047
Skip Montanaro174dd222005-05-14 20:54:16 +00002048- Patch #1120353: The xmlrpclib module provides better, more transparent,
2049 support for datetime.{datetime,date,time} objects. With use_datetime set
2050 to True, applications shouldn't have to fiddle with the DateTime wrapper
2051 class at all.
2052
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002053- distutils.commands.upload was added to support uploading distribution
2054 files to PyPI.
2055
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002056- distutils.commands.register now encodes the data as UTF-8 before posting
2057 them to PyPI.
2058
Raymond Hettinger267b8682005-03-27 10:47:39 +00002059- decimal operator and comparison methods now return NotImplemented
2060 instead of raising a TypeError when interacting with other types. This
2061 allows other classes to implement __radd__ style methods and have them
2062 work as expected.
2063
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002064- Bug #1163325: Decimal infinities failed to hash. Attempting to
2065 hash a NaN raised an InvalidOperation instead of a TypeError.
2066
Tim Petersecc6e6a2005-07-10 22:30:55 +00002067- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002068 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2069

2073 to build.
2074
Martin v. Löwis637431b2005-03-03 23:12:42 +00002075- Patch #1103407: Properly deal with tarfile iterators when untarring

Raymond Hettingerbab41432005-02-05 01:31:19 +00002100- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2101
Guido van Rossumd0641422005-02-03 15:01:24 +00002102- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2103 disables recursive traversal through instance attributes, which can
2104 be exploited in various ways.
2105
Tim Peterse3547fd2005-12-16 23:13:57 +00002106- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002107 flags on the HTTP listening socket.
2108
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002109- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2110 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2111
Fred Drakefbdeaad2006-07-29 16:56:15 +00002112- Patches #893642, #1039083: add allow_none, encoding arguments to
2113 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002114
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002115- Bug #1110478: Revert os.environ.update to do putenv again.
2116
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002117- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2118
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002119- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2120
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002121- Enhancements to the csv module:
2122
2123 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002124 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002125 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002126 + Dialect parameter parsing has been re-implemented to improve error
2127 reporting.
2128 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2129 dictates.
2130 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002131 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002132 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002133 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2134 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002135 + reader now allows \r characters to be quoted (previously it only allowed
2136 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002137 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002138 + Dialect classes passed to the module are no longer instantiated by
2139 the module before being parsed (the former validation scheme required
2140 this, but the mechanism was unreliable).
2141 + The dialect registry now contains instances of the internal
2142 C-coded dialect type, rather than references to python objects.
2143 + the internal c-coded dialect type is now immutable.
2144 + register_dialect now accepts the same keyword dialect specifications
2145 as the reader and writer, allowing the user to register dialects
2146 without first creating a dialect class.
2147 + a configurable limit to the size of parsed fields has been added -
2148 previously, an unmatched quote character could result in the entire
2149 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002150 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002151 the parser field size limit (returning the former limit). The initial
2152 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002153 + A line_num attribute has been added to the reader object, which tracks
2154 the number of lines read from the source iterator. This is not
2155 the same as the number of records returned, as records can span
2156 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002157 + reader and writer objects were not being registered with the cyclic-GC.
2158 This has been fixed.
2159
Brett Cannone6539c42005-01-08 02:43:53 +00002160- _DummyThread objects in the threading module now delete self.__block that is
2161 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2162 lock primitives tend to be limited in number and thus should not be wasted on
2163 a _DummyThread object. Fixes bug #1089632.
2164
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002165- The imghdr module now detects Exif files.
2166
Raymond Hettinger6065d322004-12-20 23:51:53 +00002167- StringIO.truncate() now correctly adjusts the size attribute.
2168 (Bug #951915).
2169
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002170- locale.py now uses an updated locale alias table (built using
2171 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2172 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002173 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002174
Raymond Hettinger3557f422004-12-07 12:02:02 +00002175- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2176
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002177- the pickle module no longer accepts the deprecated None option in the
2178 args tuple returned by __reduce__().
2179
Brett Cannon84667c02004-12-07 03:25:18 +00002180- optparse now optionally imports gettext. This allows its use in setup.py.
2181
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002182- the pickle module no longer uses the deprecated bin parameter.
2183
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002184- the shelve module no longer uses the deprecated binary parameter.
2185
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002186- the pstats module no longer uses the deprecated ignore() method.
2187
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002188- the filecmp module no longer uses the deprecated use_statcache argument.
2189
Raymond Hettinger664347b2004-12-04 21:21:53 +00002190- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2191 extended or overridden by subclasses. Formerly, the subclassed method would
2192 be ignored by the rest of the module. (Bug #1078905).
2193
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002194- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002195 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002196
Walter Dörwald36733692004-12-22 12:50:50 +00002197- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2198 once when a size argument is given. This prevents a buffer overflow in the
2199 tokenizer with very long source lines.
2200
Barry Warsaw538561e2006-01-01 21:48:54 +00002201- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2202 immediately after creating the object, without any intervening
2203 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002204
Skip Montanaro05885812005-01-16 20:48:27 +00002205- The reconvert.quote function can now emit triple-quoted strings. The
2206 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002207
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002208- ``UserString.MutableString`` now supports negative indices in
2209 ``__setitem__`` and ``__delitem__``
2210
Greg Ward40407942005-03-05 02:53:17 +00002211- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2212 correctly.
2213
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002214- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2215 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2216 character even if the user has passed a size parameter to get a proper
2217 line ending. Remove the special handling of a "\r\n" that has been split
2218 between two lines.
2219
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002220- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2221 about illegal code points. The codec now supports PEP 293 style error
2222 handlers.
2223
Walter Dörwald78a78b02005-09-01 12:04:29 +00002224- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002225 from the input stream, so that the output is a byte string in the correct
2226 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002227
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002228- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2229 considering it exactly like a '*'.
2230
Walter Dörwald007f8df2005-10-09 19:42:27 +00002231- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2232 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002233
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002234- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2235
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002236- Patch #1413711: Certain patterns of differences were making difflib
2237 touch the recursion limit.
2238
Walter Dörwald58917a62006-03-31 15:26:22 +00002239- Bug #947906: An object oriented interface has been added to the calendar
2240 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002241 called as a script (e.g. via ``python -mcalendar``). Localized month and
2242 weekday names can be ouput (even if an exotic encoding is used) using
2243 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002244

Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002259- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2260 The zlib module is now builtin on Windows.
2261
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002262- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2263
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002264- Bug #1189330: configure did not correctly determine the necessary
2265 value of LINKCC if python was built with GCC 4.0.
2266
Trent Mick8321b422005-07-26 02:29:21 +00002267- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2268 vulnerability in zlib 1.2.1 and 1.2.2.
2269
Brett Cannon08cd5982005-04-24 22:26:38 +00002270- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2271 flags that change binary compatibility. Changes were also made to
2272 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002273 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002274
Bob Ippolitoed233462005-03-29 13:47:59 +00002275- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2276 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2277 no longer exists). This configure patch makes things right.
2278
Martin v. Löwise2713be2005-03-08 15:03:08 +00002279- Bug #1158607: Build with --disable-unicode again.
2280
Brett Cannon46d96232005-02-16 00:07:19 +00002281- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2282 defined. Discovered as a result of not being able to build on OS X.
2283
Brett Cannon516592f2004-12-07 00:42:59 +00002284- setup.py now uses the directories specified in LDFLAGS using the -L option
2285 and in CPPFLAGS using the -I option for adding library and include
2286 directories, respectively, for compiling extension modules against. This has
2287 led to the core being compiled using the values in CPPFLAGS. It also removes
2288 the need for the special-casing of both DarwinPorts and Fink for darwin since
2289 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2290 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2291 Fink, ``-I/opt/local/include`` for DarwinPorts).

Brett Cannon43802422005-02-10 20:48:03 +00002293- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2294 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2295 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2296 Closes bug #1096244. Thanks Gregory Bond.

Tim Petersc9d78aa2006-03-26 23:27:58 +00002301- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2302 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2303 is obtained via the ``PyObject_`` family, it must be released via the
2304 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2305 always been officially true, but when Python's small-object allocator was
2306 introduced, an attempt was made to cater to a few extension modules
2307 discovered at the time that obtained memory via ``PyObject_New`` but
2308 released it via ``PyMem_DEL``. It's years later, and if such code still
2309 exists it will fail now (probably with segfaults, but calling wrong
2310 low-level memory management functions can yield many symptoms).
2311
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002312- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002316- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2317 mapping argument now. This string is used as a mapping table. Byte values
2318 greater than the length of the string and 0xFFFE are treated as undefined
2319 mappings.
