109
Brett Cannon19d76c52006-09-09 07:18:44 +0000110- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000128- The return tuple from str.rpartition(sep) is (tail, sep, head) where
129 head is the original string if sep was not found.
130
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000131- Bug #1520864: unpacking singleton tuples in list comprehensions and
132 generator expressions (x for x, in ... ) works again. Fixing this problem
133 required changing the .pyc magic number. This means that .pyc files
134 generated before 2.5c2 will be regenerated.
135
Neal Norwitz19c35bb2006-08-21 22:13:11 +0000136

Guido van Rossumc69ac252006-08-10 18:09:25 +0000225What's New in Python 2.5 release candidate 1?

230Core and builtins
231-----------------
232
Neal Norwitz24b6f202006-09-05 04:43:56 +0000233- Fix infinite recursion when subclassing long and overriding __hash__.
234
235- Fix concatenation (+=) of long strings.
236
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000237- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000238 compared equal or unequal to a string and a UnicodeDecodeError
239 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000240
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000241 Instead, the equal (==) and unequal (!=) comparison operators will
242 now issue a UnicodeWarning and interpret the two objects as
243 unequal. The UnicodeWarning can be filtered as desired using
244 the warning framework, e.g. silenced completely, turned into an
245 exception, logged, etc.
246
247 Note that compare operators other than equal and unequal will still
248 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000249
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000250- Fix segfault when doing string formatting on subclasses of long.
251
252- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
253 with new-style classes.
254
255- Fix bug related to __len__ functions returning negative values with
256 classic classes.
257
258- Patch #1538606, Fix __index__() clipping. There were some problems
259 discovered with the API and how integers that didn't fit into Py_ssize_t
260 were handled. This patch attempts to provide enough alternatives
261 to effectively use __index__.
262
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000263- Bug #1536021: __hash__ may now return long int; the final hash
264 value is obtained by invoking hash on the long int.
265
Thomas Hellerab1049c2006-08-08 17:37:00 +0000266- Bug #1536786: buffer comparison could emit a RuntimeWarning.
267
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000268- Bug #1535165: fixed a segfault in input() and raw_input() when
269 sys.stdin is closed.
270
Thomas Heller74d36f02006-08-04 18:17:40 +0000271- On Windows, the PyErr_Warn function is now exported from
272 the Python dll again.
273
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000274- Bug #1191458: tracing over for loops now produces a line event
275 on each iteration. Fixing this problem required changing the .pyc
276 magic number. This means that .pyc files generated before 2.5c1
277 will be regenerated.
278
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000279- Bug #1333982: string/number constants were inappropriately stored
280 in the byte code and co_consts even if they were not used, ie
281 immediately popped off the stack.
282
Georg Brandle9462c72006-08-04 18:03:37 +0000283- Fixed a reference-counting problem in property().

287-------
288
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000289- Fix a bug in the ``compiler`` package that caused invalid code to be
290 generated for generator expressions.
291
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000292- The distutils version has been changed to 2.5.0. The change to
293 keep it programmatically in sync with the Python version running
294 the code (introduced in 2.5b3) has been reverted. It will continue
295 to be maintained manually as static string literal.
296
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000297- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000298 and this cannot be converted to the required C type, an exception is
299 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000300 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000301
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000302- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000303 an exception.
304
Tim Peterscbdd3502006-09-05 01:47:53 +0000305- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000306 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000307 workarounds for clocks with low resolution, to stop the code yielding
308 duplicate UUIDs.
309
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000310- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
311 before raising SystemExit, allowing IDLE to honor quit() and exit().
312
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000313- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
314
Georg Brandl7a1af772006-08-14 21:55:28 +0000315- Patch #1536071: trace.py should now find the full module name of a
316 file correctly even on Windows.
317
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000318- logging's atexit hook now runs even if the rest of the module has

342
Thomas Heller86720042006-08-14 11:17:48 +0000343- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
344 uses the _as_parameter_ attribute when objects are passed to foreign

346
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000347- Bug #1530559, struct.pack raises TypeError where it used to convert.

Fred Drake53912162006-07-29 13:22:49 +0000394What's New in Python 2.5 beta 3?
395================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000396
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000397*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000398
399Core and builtins
400-----------------
401
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000402- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000403 returned a long (see PEP 353).
404
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000405- Bug #1515471: string.replace() accepts character buffers again.
406
Neal Norwitz07aadb12006-07-30 06:55:48 +0000407- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
408 This provides the proper warning for struct.pack().
409 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
410
Neal Norwitz0d62a062006-07-30 06:53:31 +0000411- Patch #1531113: Fix augmented assignment with yield expressions.
412 Also fix a SystemError when trying to assign to yield expressions.
413
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000414- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
415 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
416 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
417 excessive filesystem operations during imports.
418
Tim Petersbc24eee2006-07-27 01:14:53 +0000419- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
420 operations on signed longs that are formally undefined by C.
421 Unfortunately, at least one compiler now cares about that, so complicated
422 the code to make that compiler happy again.
423
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000424- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
425
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000426- Patch #1232023: Stop including current directory in search
427 path on Windows.
428
Neal Norwitze1fdb322006-07-21 05:32:28 +0000429- Fix some potential crashes found with failmalloc.
430
Neal Norwitze7563102006-07-17 01:00:16 +0000431- Fix warnings reported by Klocwork's static analysis tool.
432
Neal Norwitz84be93b2006-07-16 01:50:38 +0000433- Bug #1512814, Fix incorrect lineno's when code within a function
434 had more than 255 blank lines.
435
Georg Brandl9dceedb2006-07-12 15:31:17 +0000436- Patch #1521179: Python now accepts the standard options ``--help`` and
437 ``--version`` as well as ``/?`` on Windows.
438
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000439- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000440 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000441 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000442
Tim Peters112aad32006-07-19 00:03:19 +0000443- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000444 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000445 new ``sys._current_frames()`` returns a dictionary with one entry,
446 mapping the faux "thread id" 0 to the current frame.
447
Ronald Oussoren3075e162006-07-25 20:28:55 +0000448- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000449

Neal Norwitza1f10902006-07-12 07:28:29 +0000451Library
452-------
453
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000454- Correction of patch #1455898: In the mbcs decoder, set final=False
455 for stream decoder, but final=True for the decode function.
456
Georg Brandl07fec3a2006-08-01 18:49:24 +0000457- os.urandom no longer masks unrelated exceptions like SystemExit or
458 KeyboardInterrupt.
459
Tim Peters4643c2f2006-08-10 22:45:34 +0000460- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000461 shutil.copytree on Windows
462
Georg Brandle34ac7c2006-07-30 11:07:23 +0000463- Bug #1002398: The documentation for os.path.sameopenfile now correctly
464 refers to file descriptors, not file objects.
465
Tim Peterscbdd3502006-09-05 01:47:53 +0000466- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000467 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000468 #1513611, and probably others.
469
Georg Brandledd9b0d2006-07-29 09:33:26 +0000470- Bug #1441397: The compiler module now recognizes module and function
471 docstrings correctly as it did in Python 2.4.
472
Tim Peters6f681472006-07-27 23:44:37 +0000473- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
474 lost that tests are sorted by name before being run. This rarely
475 matters for well-written tests, but can create baffling symptoms if
476 side effects from one test to the next affect outcomes. ``DocTestFinder``
477 has been changed to sort the list of tests it returns.
478
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000479- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000480 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000481
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000482- Bug #978833: Really close underlying socket in _socketobject.close.
483
Georg Brandldb232dc2006-08-20 13:15:43 +0000484- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
485 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000486
Georg Brandlcf0c1722006-07-26 07:23:32 +0000487- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
488 to recursive calls and call it with the failing package name.
489
Martin v. Löwis0b483032006-07-25 09:53:12 +0000490- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
491
Georg Brandlc13c34c2006-07-24 14:09:56 +0000492- Patch #1515343: Fix printing of deprecated string exceptions with a
493 value in the traceback module.
494
Greg Ward48fae7a2006-07-23 16:05:51 +0000495- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
496
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000497- Patch #1524429: Use repr() instead of backticks in Tkinter again.
498
Brett Cannoncaebe222006-07-18 04:41:36 +0000499- Bug #1520914: Change time.strftime() to accept a zero for any position in its
500 argument tuple. For arguments where zero is illegal, the value is forced to
501 the minimum value that is correct. This is to support an undocumented but
502 common way people used to fill in inconsequential information in the time
503 tuple pre-2.4.
504
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000505- Patch #1220874: Update the binhex module for Mach-O.
506
Barry Warsawb110bad2006-07-21 14:51:07 +0000507- The email package has improved RFC 2231 support, specifically for
508 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
509 (name*0=<blah>) parameter continuations. This may change the types of
510 values returned from email.message.Message.get_param() and friends.
511 Specifically in some cases where non-encoded continuations were used,
512 get_param() used to return a 3-tuple of (None, None, string) whereas now it
513 will just return the string (since non-encoded continuations don't have
514 charset and language parts).
515
516 Also, whereas % values were decoded in all parameter continuations, they are
517 now only decoded in encoded parameter parts.
518
Ronald Oussoren3075e162006-07-25 20:28:55 +0000519- Bug #1517990: IDLE keybindings on MacOS X now work correctly
520
521- Bug #1517996: IDLE now longer shows the default Tk menu when a
522 path browser, class browser or debugger is the frontmost window on MacOS X
523
Barry Warsaw00decd72006-07-27 23:43:15 +0000524- Patch #1520294: Support for getset and member descriptors in types.py,
525 inspect.py, and pydoc.py. Specifically, this allows for querying the type
526 of an object against these built-in types and more importantly, for getting
527 their docstrings printed in the interactive interpreter's help() function.

532
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000533- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
534 a socket operation on a socket with a timeout, the exception will be
535 caught correctly. Previously, the exception was not caught.
536
Thomas Heller1393d6a2006-07-28 21:43:20 +0000537- Patch #1529514: The _ctypes extension is now compiled on more
538 openbsd target platforms.
539
Tim Peters9cab5932006-07-28 00:30:00 +0000540- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
541 a memory leak, affecting pickles and deep copies.
542
Tim Petersbc24eee2006-07-27 01:14:53 +0000543- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000544 Paul Eggert.
545
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000546- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
547
Thomas Hellerce049a02006-07-14 17:51:14 +0000548- Patch #1521817: Index range checking on ctypes arrays containing
549 exactly one element enabled again. This allows iterating over these
550 arrays, without the need to check the array size before.
551
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000552- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000553 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000554 /dev/null in certain cases; this is now fixed.
555
Thomas Heller47d7a062006-07-12 08:43:47 +0000556- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
557 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000558
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000559- Because of a misspelled preprocessor symbol, ctypes was always
560 compiled without thread support; this is now fixed.
561
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000562- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
563 methods now allow their database parameter to be None as the
564 sleepycat API allows.
565
Matt Flemingec926502006-07-28 11:27:27 +0000566- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
567 bluetooth API compared with Linux and FreeBSD.
568
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000569Tests
570-----
571
572- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
573 how long the test file should take to play. Now accepts taking 2.93 secs
574 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
575
Georg Brandl4793aa32006-07-28 18:31:39 +0000576- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
577 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
578 run via ``regrtest.py``. Now they do.

587
588- PythonLauncher now works correctly when the path to the script contains
589 characters that are treated specially by the shell (such as quotes).
590
591- Bug #1527397: PythonLauncher now launches scripts with the working directory
592 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000593 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000594 expect.

606 again evaluates to a int object, not a long.
607
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000608- Bug #1501934: The scope of global variables that are locally assigned

Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000617- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
618 omit a default "error" argument for NULL pointer. This allows
619 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000620
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000621- Bug #1519018: 'as' is now validated properly in import statements.
622
Neal Norwitz28746ab2006-07-09 22:14:42 +0000623- On 64 bit systems, int literals that use less than 64 bits are
624 now ints rather than longs.
625
Neal Norwitzed657552006-07-10 00:04:44 +0000626- Bug #1512814, Fix incorrect lineno's when code at module scope
627 started after line 256.
628
Tim Peters32a83612006-07-10 21:08:24 +0000629- New function ``sys._current_frames()`` returns a dict mapping thread
630 id to topmost thread stack frame. This is for expert use, and is
631 especially useful for debugging application deadlocks. The functionality
632 was previously available in Fazal Majid's ``threadframe`` extension
633 module, but it wasn't possible to do this in a wholly threadsafe way from
634 an extension.

654 be treated as the value they contain, instead.
655
Martin v. Löwisede77f52006-07-03 13:01:35 +0000656- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

681
Brett Cannon53ab5b72006-06-22 16:49:14 +0000682- Bug #1510580: The 'warnings' module improperly required that a Warning
683 category be either a types.ClassType and a subclass of Warning. The proper
684 check is just that it is a subclass with Warning as the documentation states.
685
Georg Brandlad29e632006-06-21 17:45:17 +0000686- The compiler module now correctly compiles the new try-except-finally

Tim Peters112aad32006-07-19 00:03:19 +0000701- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
702 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
703 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000704
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000705- Assigning None to pointer type fields in ctypes structures possible
706 overwrote the wrong fields, this is fixed now.
707
708- Fixed a segfault in _ctypes when ctypes.wintypes were imported
709 on non-Windows platforms.
710
711- Bug #1518190: The ctypes.c_void_p constructor now accepts any
712 integer or long, without range checking.
713
714- Patch #1517790: It is now possible to use custom objects in the ctypes
715 foreign function argtypes sequence as long as they provide a from_param
716 method, no longer is it required that the object is a ctypes type.
717
718- The '_ctypes' extension module now works when Python is configured
719 with the --without-threads option.

736
Tim Peters32a83612006-07-10 21:08:24 +0000737- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000738 Previously, the slight difference could cause compilation errors of the
739 'zlib' module on systems with more than one version of zlib.
740
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000741- The MSI compileall step was fixed to also support a TARGETDIR

772Core and builtins
773-----------------
774
Georg Brandla56b9152006-06-19 06:35:54 +0000775- Patch #1507676: Error messages returned by invalid abstract object operations
776 (such as iterating over an integer) have been improved and now include the
777 type of the offending object to help with debugging.
778
Brett Cannonea3912b2006-06-13 21:46:41 +0000779- Bug #992017: A classic class that defined a __coerce__() method that returned
780 its arguments swapped would infinitely recurse and segfault the interpreter.
781
Neal Norwitz909eb122006-06-12 02:13:21 +0000782- Fix the socket tests so they can be run concurrently.
783
Neal Norwitzb9845e72006-06-12 02:11:18 +0000784- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000785 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000786
Brett Cannon22565aa2006-06-09 22:31:23 +0000787- Bug #532646: object.__call__() will continue looking for the __call__
788 attribute on objects until one without one is found. This leads to recursion
789 when you take a class and set its __call__ attribute to an instance of the
790 class. Originally fixed for classic classes, but this fix is for new-style.
791 Removes the infinite_rec_3 crasher.
792
Georg Brandl24250812006-06-09 18:45:48 +0000793- The string and unicode methods startswith() and endswith() now accept
794 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
795
Brett Cannonde3b0522006-06-08 17:00:45 +0000796- Buffer objects, at the C level, never used the char buffer
797 implementation even when the char buffer for the wrapped object was
798 explicitly requested (originally returned the read or write buffer).
799 Now a TypeError is raised if the char buffer is not present but is
800 requested.
801
Georg Brandlddbaa662006-06-04 21:56:52 +0000802- Patch #1346214: Statements like "if 0: suite" are now again optimized
803 away like they were in Python 2.4.
804
Georg Brandlb7c8f542006-05-27 12:30:25 +0000805- Builtin exceptions are now full-blown new-style classes instead of
806 instances pretending to be classes, which speeds up exception handling
807 by about 80% in comparison to 2.5a2.
808
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000809- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
810 Unicode 4.1.
811
Georg Brandlf4ef1162006-05-26 18:03:31 +0000812- Patch #921466: sys.path_importer_cache is now used to cache valid and
813 invalid file paths for the built-in import machinery which leads to
814 fewer open calls on startup.
815
Tim Peters696cf432006-05-24 21:10:40 +0000816- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
817 of-2 bases. The largest speedup is for inputs with about 1000 decimal
818 digits. Conversion from non-power-of-2 bases remains quadratic-time in
819 the number of input digits (it was and remains linear-time for bases
820 2, 4, 8, 16 and 32).
821
Tim Petersb713ec22006-05-23 18:45:30 +0000822- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
823 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
824 an integer close to ``sys.maxint``. This was repaired by patch
825 #1335972, which also gives a nice speedup.
826
Richard Jonescebbefc2006-05-23 18:28:17 +0000827- Patch #1337051: reduced size of frame objects.
828
829- PyErr_NewException now accepts a tuple of base classes as its
830 "base" parameter.
831
Richard Jones7c88dcc2006-05-23 10:37:38 +0000832- Patch #876206: function call speedup by retaining allocated frame
833 objects.
834
Georg Brandl7b90e162006-05-18 07:01:27 +0000835- Bug #1462152: file() now checks more thoroughly for invalid mode
836 strings and removes a possible "U" before passing the mode to the
837 C library function.
838
Neal Norwitz1004a532006-05-15 07:17:23 +0000839- Patch #1488312, Fix memory alignment problem on SPARC in unicode
840
Neal Norwitz373f0a72006-05-15 07:04:36 +0000841- Bug #1487966: Fix SystemError with conditional expression in assignment
842
Martin v. Löwis879768d2006-05-11 13:28:43 +0000843- WindowsError now has two error code attributes: errno, which carries
844 the error values from errno.h, and winerror, which carries the error
845 values from winerror.h. Previous versions put the winerror.h values
846 (from GetLastError()) into the errno attribute.
847
Martin v. Löwis77736712006-05-04 05:51:03 +0000848- Patch #1475845: Raise IndentationError for unexpected indent.
849
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000850- Patch #1479181: split open() and file() from being aliases for each other.
851
Tim Peters44bd9862006-06-01 13:49:23 +0000852- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
853 methods were always silently ignored by dictionaries when comparing keys.
854 They are now passed through (except when using the C API function
855 ``PyDict_GetItem()``, whose semantics did not change).
856
857- Bug #1456209: In some obscure cases it was possible for a class with a
858 custom ``__eq__()`` method to confuse dict internals when class instances
859 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
860 No, you don't have any code that did this ;-)

873
Nick Coghlanc649ec52006-05-29 12:43:05 +0000874- Patch #1478788 (modified version): The functional extension module has
875 been renamed to _functools and a functools Python wrapper module added.
876 This provides a home for additional function related utilities that are
877 not specifically about functional programming. See PEP 309.
878
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000879- Patch #1493701: performance enhancements for struct module.

890 (up to the system limit of 32K characters).
891
892- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
893 As a result, these functions now raise WindowsError instead of OSError.
894
Tim Peters7a822da2006-05-25 21:50:17 +0000895- ``time.clock()`` on Win64 should use the high-performance Windows
896 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
897 Windows platforms).
898
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000899- Calling Tk_Init twice is refused if the first call failed as that
900 may deadlock.
901
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000902- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
903 accept it without potentially using an uninitialized pointer.
904
905- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
906 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smith506f7b52006-06-15 08:52:32 +0000923- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000924 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000925 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
926 database calls that would previously deadlock. [SF python bug #775414]
927
Vinay Sajip28e57612006-07-01 10:45:20 +0000928- Patch #1446489: add support for the ZIP64 extensions to zipfile.

950 mime.types file for determining MIME types.
951
Georg Brandl2605ca82006-06-14 06:08:31 +0000952- Bug #1339007: Shelf objects now don't raise an exception in their
953 __del__ method when initialization failed.
954
Martin v. Löwisd8251432006-06-14 05:21:04 +0000955- Patch #1455898: The MBCS codec now supports the incremental mode for
956 double-byte encodings.
957
Tim Peters43898b42006-06-14 04:09:25 +0000958- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
959 guarantee that adjacent triples in the return list always describe
960 non-adjacent blocks. Previously, a pair of matching blocks could end
961 up being described by multiple adjacent triples that formed a partition
962 of the matching pair.
963
Greg Ward0e0c9f42006-06-11 16:24:11 +0000964- Bug #1498146: fix optparse to handle Unicode strings in option help,
965 description, and epilog.
966
Greg Wardd1c797e2006-06-11 14:42:41 +0000967- Bug #1366250: minor optparse documentation error.
968
Greg Ward7f547402006-06-11 00:40:49 +0000969- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
970 clarify docs.
971
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000972- The wsgiref package has been added to the standard library.
973
Nick Coghlan676725d2006-06-08 13:54:49 +0000974- The functions update_wrapper() and wraps() have been added to the functools
975 module. These make it easier to copy relevant metadata from the original
976 function when writing wrapper functions.
977
Tim Petersd6a9eef2006-06-05 01:48:21 +0000978- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
979 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000980
Martin v. Löwis3f767792006-06-04 19:36:28 +0000981- Patch #1359618: Speed up charmap encoder by using a trie structure
982 for lookup.
983
Tim Petersd609b1a2006-06-02 23:22:51 +0000984- The functions in the ``pprint`` module now sort dictionaries by key
985 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
986 if and only if its display required more than one line, although that
987 wasn't documented. The new behavior increases predictability; e.g.,
988 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
989
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000990- Patch #1497027: try HTTP digest auth before basic auth in urllib2

994 default HTTP and HTTPS ports.
995

999
Georg Brandlb89316f2006-05-17 15:51:16 +00001000- Patch #1180296: Two new functions were added to the locale module:
1001 format_string() to get the effect of "format % items" but locale-aware,
1002 and currency() to format a monetary number with currency sign.
1003
Georg Brandle3a25832006-05-17 14:56:04 +00001004- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1005 and several features added, such as speed and geometry control.
1006
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001007- Patch #1488881: add support for external file objects in bz2 compressed
1008 tarfiles.
1009
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001010- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1011 stdout arguments, making it possible to redirect input and output
1012 for remote debugging.
1013
1014- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1015 a couple of issues, notably handling of long file names using the
1016 GNU LONGNAME extension.
1017
1018- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1019 new flag when ``name`` is already the name of an option flag.
1020
1021- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1022 package.
1023
1024- Patch #1472854: make the rlcompleter.Completer class usable on non-
1025 UNIX platforms.
1026
1027- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1028
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001029- Bug #1472827: correctly escape newlines and tabs in attribute values in
1030 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001060What's New in Python 2.5 alpha 2?
1061=================================
1062
1063*Release date: 27-APR-2006*
1064
1065Core and builtins
1066-----------------
1067
Thomas Heller1b046642006-04-18 18:51:06 +00001068- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1069 by converting these apis from macros into exported functions again:
1070
1071 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1072 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1073 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1074 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1075 PyRun_String Py_CompileString
1076
Martin v. Löwis45294a92006-04-18 06:24:08 +00001077- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1078
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001079- All uses of PyStructSequence_InitType have been changed to initialize
1080 the type objects only once, even if the interpreter is initialized
1081 multiple times.
1082
Neal Norwitz61546162006-04-14 05:20:28 +00001083- Bug #1454485, array.array('u') could crash the interpreter. This was
1084 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1085 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1086
1087- Py_UNICODE is unsigned. It was always documented as unsigned, but
1088 due to a bug had a signed value in previous versions.
1089
Tim Peters3a5e8b12006-04-11 01:44:07 +00001090- Patch #837242: ``id()`` of any Python object always gives a positive
1091 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1092 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001093 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001094 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001095
Tim Peters3a5e8b12006-04-11 01:44:07 +00001096 def __hash__(self):
1097 return id(self) # WRONG
1098
1099 because a hash result must be a (short) Python int but it was always
1100 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001101 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001102 was always usable as a hash value before this patch. That's no longer
1103 necessarily so.
1104
1105- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001106 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001107 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001108 #1454844)
1109
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001110- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1111 involving generators that have paused outside of any ``try`` or ``with``
1112 blocks. (In 2.5a1, a paused generator that was part of a reference
1113 cycle could not be garbage collected, regardless of whether it was
1114 paused in a ``try`` or ``with`` block.)

1148 or exception is ignored).
1149
Nick Coghlanda2268f2006-04-24 04:37:15 +00001150- Fixed contextlib.nested to cope with exceptions being raised and
1151 caught inside exit handlers.
1152
Greg Wardab05edc2006-04-23 03:47:58 +00001153- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1154 hex, octal, or binary; add ``append_const`` action; keep going if
1155 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1156 added ``epilog`` for better help generation).
1157
Tim Peters21fbd572006-04-21 21:18:10 +00001158- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1159 called from a thread spawned as a side effect of importing a module.
1160
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001161- The pydoc module now supports documenting packages contained in
1162 .zip or .egg files.
1163
1164- The pkgutil module now has several new utility functions, such
1165 as ``walk_packages()`` to support working with packages that are either
1166 in the filesystem or zip files.
1167
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001168- The mailbox module can now modify and delete messages from

1170 K. Johnson for writing the code, and to the 2005 Google Summer of
1171 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001172
Tim Petersc7605f22006-04-17 21:12:33 +00001173- The ``__del__`` method of class ``local`` in module ``_threading_local``
1174 returned before accomplishing any of its intended cleanup.
1175
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001176- Patch #790710: Add breakpoint command lists in pdb.

Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001230- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1231 it separately and by hand. It also wasn't cleaning up its changes to
1232 the current Decimal context.
1233
Thomas Woutersabd08882006-04-26 15:53:30 +00001234- regrtest.py now has a -M option to run tests that test the new limits of
1235 containers, on 64-bit architectures. Running these tests is only sensible
1236 on 64-bit machines with more than two gigabytes of memory. The argument
1237 passed is the maximum amount of memory for the tests to use.

1246-------------
1247
Tim Petersb06d28c2006-05-12 01:57:59 +00001248- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1249
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001250- PEP 343: Added Context Types section to the library reference
1251 and attempted to bring other PEP 343 related documentation into
1252 line with the implementation and/or python-dev discussions.
1253
Tim Peters8dc73d22006-04-24 02:03:16 +00001254- Bug #1337990: clarified that ``doctest`` does not support examples
1255 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001258What's New in Python 2.5 alpha 1?
1259=================================
1260
Anthony Baxterebed3f62006-04-03 15:03:44 +00001261*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001262
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001263Core and builtins
1264-----------------
1265
Nick Coghlan43832302006-04-23 17:04:07 +00001266- PEP 338: -m command line switch now delegates to runpy.run_module
1267 allowing it to support modules in packages and zipfiles
1268
Martin v. Löwisc661b882006-04-20 04:54:23 +00001269- On Windows, .DLL is not an accepted file name extension for
1270 extension modules anymore; extensions are only found if they
1271 end in .PYD.
1272
Martin v. Löwisea62d252006-04-03 10:56:49 +00001273- Bug #1421664: sys.stderr.encoding is now set to the same value as
1274 sys.stdout.encoding.
1275
Neal Norwitz92e212f2006-04-03 04:48:37 +00001276- __import__ accepts keyword arguments.
1277
Georg Brandlccadf842006-03-31 18:54:53 +00001278- Patch #1460496: round() now accepts keyword arguments.
1279
Anthony Baxter262c00a2006-03-30 10:53:17 +00001280- Fixed bug #1459029 - unicode reprs were double-escaped.
1281
Hye-Shik Changd478f342006-03-23 12:32:36 +00001282- Patch #1396919: The system scope threads are reenabled on FreeBSD
1283 5.4 and later versions.
1284
Neal Norwitze98ccf62006-03-23 05:39:47 +00001285- Bug #1115379: Compiling a Unicode string with an encoding declaration
1286 now gives a SyntaxError.
1287
Georg Brandlabd1ff82006-03-18 07:59:59 +00001288- Previously, Python code had no easy way to access the contents of a
1289 cell object. Now, a ``cell_contents`` attribute has been added
1290 (closes patch #1170323).
1291
Tim Peterscf79aac2006-03-16 01:14:46 +00001292- Patch #1123430: Python's small-object allocator now returns an arena to
1293 the system ``free()`` when all memory within an arena becomes unused
1294 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1295 freed. Some applications will see a drop in virtual memory size now,
1296 especially long-running applications that, from time to time, temporarily
1297 use a large number of small objects. Note that when Python returns an
1298 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001299 platform C library will in turn return that memory to the operating system.
1300 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001301 appears to be effective at least on Microsoft C and gcc-based systems.
1302 Thanks to Evan Jones for hard work and patience.
1303
Georg Brandl533ff6f2006-03-08 18:09:27 +00001304- Patch #1434038: property() now uses the getter's docstring if there is
1305 no "doc" argument given. This makes it possible to legitimately use
1306 property() as a decorator to produce a read-only property.
1307
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001308- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1309 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1310 of requiring an int or long in slicing and a few other contexts, enabling
1311 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1312
Neal Norwitz995acdf2006-03-07 05:01:00 +00001313- Fixed various bugs reported by Coverity's Prevent tool.
1314
Brett Cannonbf364092006-03-01 04:25:17 +00001315- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1316 new exception base class, BaseException, which has a new message attribute.
1317 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1318 Raising a string exception now raises a DeprecationWarning.
1319
Thomas Woutersfb609f42006-02-28 16:37:25 +00001320- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1321 explicitly relative, using 'from .module import name' to mean 'from the same
1322 package as this module is in. Imports without dots still default to the
1323 old relative-then-absolute, unless 'from __future__ import
1324 absolute_import' is used.
1325
Brett Cannona7446e32006-02-27 23:39:10 +00001326- Properly check if 'warnings' raises an exception (usually when a filter set
1327 to "error" is triggered) when raising a warning for raising string
1328 exceptions.
1329
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001330- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001331 The name was removed from Include/code.h.
1332
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001333- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001334
Guido van Rossum1968ad32006-02-25 22:38:04 +00001335- Patch 1433928:
1336 - The copy module now "copies" function objects (as atomic objects).
1337 - dict.__getitem__ now looks for a __missing__ hook before raising
1338 KeyError.
1339
Tim Peters84ef21c2006-02-28 20:39:06 +00001340- PEP 343: with statement implemented. Needs ``from __future__ import
1341 with_statement``. Use of 'with' as a variable will generate a warning.
1342 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001343 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001344 The following objects have __context__ methods:
1345 - The built-in file type.
1346 - The thread.LockType type.
1347 - The following types defined by the threading module:
1348 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1349 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001350
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001351- Fix the encodings package codec search function to only search
1352 inside its own package. Fixes problem reported in patch #1433198.
1353
1354 Note: Codec packages should implement and register their own
1355 codec search function. PEP 100 has the details.
1356
Tim Peters9ea89d22006-06-04 03:26:02 +00001357- PEP 353: Using ``Py_ssize_t`` as the index type.
1358
1359- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1360 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1361 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1362 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1363 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001364
Neal Norwitzfc76d632006-01-10 06:03:13 +00001365- Patch #1400181, fix unicode string formatting to not use the locale.
1366 This is how string objects work. u'%f' could use , instead of .
1367 for the decimal point. Now both strings and unicode always use periods.
1368
Neal Norwitz671b9e32006-01-09 07:07:12 +00001369- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1370 configure would break checking curses.h.
1371
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001372- Bug #959576: The pwd module is now builtin. This allows Python to be
1373 built on UNIX platforms without $HOME set.
1374
Neal Norwitzc10978f2005-12-19 06:07:16 +00001375- Bug #1072182, fix some potential problems if characters are signed.
1376
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001377- Bug #889500, fix line number on SyntaxWarning for global declarations.
1378
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001379- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1380
Neal Norwitze7214a12005-12-18 05:03:17 +00001381- Support for converting hex strings to floats no longer works.
1382 This was not portable. float('0x3') now raises a ValueError.
1383
Barry Warsaw2a38a862005-12-18 01:27:35 +00001384- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001385 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001386 is now displayed in interactive prompt banner.
1387
Georg Brandlfa166682005-12-17 21:45:17 +00001388- Implementation of PEP 341 - Unification of try/except and try/finally.
1389 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001390 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001391
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001392- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1393 now encodes backslash correctly.
1394
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001395- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1396
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001397- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001398 and long longs.
1399
Neal Norwitz67715f02005-11-09 06:59:35 +00001400- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001401 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001402 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001403
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001404- Replaced most Unicode charmap codecs with new ones using the
1405 new Unicode translate string feature in the builtin charmap
1406 codec; the codecs were created from the mapping tables available
1407 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1408 encodings now include a mapping for the Apple logo)
1409
Tim Peterse3547fd2005-12-16 23:13:57 +00001410- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001411
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001412- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001413
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001414- A new AST parser implementation was completed. The abstract
1415 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001416 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001417
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001418- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001419 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1420
Neal Norwitz708e51a2005-10-03 04:48:15 +00001421- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1422
Neal Norwitz11bd1192005-10-03 00:54:56 +00001423- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1424 Provide a warning when a directory is passed on the command line.
1425
Neal Norwitz40d37812005-10-02 01:48:49 +00001426- Fix segfault with invalid coding.
1427
1428- SF bug #772896: unknown encoding results in MemoryError.
1429
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001430- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001431 supported a __len__() method which evaluated to False when the iterator
1432 was empty.
1433
Guido van Rossum630db602005-09-20 18:49:54 +00001434- On 64-bit platforms, when __len__() returns a value that cannot be
1435 represented as a C int, raise OverflowError.
1436
Skip Montanarof8948ca2005-09-19 03:54:46 +00001437- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001438 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001439
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001440- SF bug #893549: parsing keyword arguments was broken with a few format
1441 codes.
1442
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001443- Changes donated by Elemental Security to make it work on AIX 5.3
1444 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1445 bug #105470: test_pwd fails on 64bit system (Opteron).
1446
Guido van Rossum539c6622005-09-14 17:49:54 +00001447- Changes donated by Elemental Security to make it work on HP-UX 11 on
1448 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1449
Georg Brandl4550b8d2005-08-26 06:43:52 +00001450- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001451 (fixes bug #1119418).
1452
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001453- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1454
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001455- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1456 exceptions that cause a function to exit.
1457
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001458- The implementation of set() and frozenset() was revised to use its
1459 own internal data structure. Memory consumption is reduced by 1/3
1460 and there are modest speed-ups as well. The API is unchanged.
1461
Tim Petersde7990b2005-07-17 23:45:23 +00001462- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1463
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001464- SF bug #1229429: PyObject_CallMethod failed to decrement some
1465 reference counts in some error exit cases.
1466
Tim Petersecc6e6a2005-07-10 22:30:55 +00001467- SF bug #1185883: Python's small-object memory allocator took over
1468 a block managed by the platform C library whenever a realloc specified
1469 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001470 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001471 portable way to copy data from the C-managed block into Python's
1472 small-object space without risking a memory fault. Python's small-object
1473 realloc now leaves such blocks under the control of the platform C
1474 realloc.
1475
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001476- SF bug #1232517: An overflow error was not detected properly when
1477 attempting to convert a large float to an int in os.utime().
1478
Raymond Hettinger3296e692005-06-29 23:29:56 +00001479- SF bug #1224347: hex longs now print with lowercase letters just
1480 like their int counterparts.
1481
Michael W. Hudson188d4362005-06-20 16:52:57 +00001482- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1483 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1484 interpreter states; back out that fix and do a better job (see
1485 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1486 for a longer write-up of the problem).
1487
Michael W. Hudsondf888462005-06-03 14:41:55 +00001488- SF patch #1180995: marshal now uses a binary format by default when
1489 serializing floats.
1490
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001491- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1492 the routines that promise to produce IEEE 754 binary representations
1493 of floats now simply copy bytes around.
1494
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001495- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1496 278.
1497
Brett Cannonc3647ac2005-04-26 03:45:26 +00001498- patch #1109424: int, long, float, complex, and unicode now check for the
1499 proper magic slot for type conversions when subclassed. Previously the
1500 magic slot was ignored during conversion. Semantics now match the way
1501 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001502 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001503 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001504 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001505
Barry Warsawc8d907c2005-04-19 23:43:40 +00001506- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1507 NULL, now raise an AttributeError when attempting to set or delete the
1508 attribute. Previously a TypeError was raised, but this was inconsistent
1509 with the equivalent pure-Python implementation.
1510
Michael W. Hudson774479c2005-04-18 08:46:17 +00001511- It is now safe to call PyGILState_Release() before
1512 PyEval_InitThreads() (note that if there is reason to believe there
1513 are multiple threads around you still must call PyEval_InitThreads()
1514 before using the Python API; this fix is for extension modules that
1515 have no way of knowing if Python is multi-threaded yet).
1516
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001517- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1518 disabled caused a crash.
1519
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001520- Bug #1165306: instancemethod_new allowed the creation of a method
1521 with im_class == im_self == NULL, which caused a crash when called.
1522
Tim Petersecc6e6a2005-07-10 22:30:55 +00001523- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001524 fixes the crash seen in bug #1165761
1525
Raymond Hettinger96229b12005-03-11 06:49:40 +00001526- Added two new builtins, any() and all().
1527
Brett Cannon409d8f22005-03-05 06:47:57 +00001528- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001529 (e.g., ``class C(): pass`` is no longer a syntax error).
1530 Patch #1176012 added support to the 'parser' module and 'compiler' package
1531 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001532

1536 returning None.
1537
Tim Petersecc6e6a2005-07-10 22:30:55 +00001538- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001539 ('\') with a specific error message.
1540
Martin v. Löwisff232d72005-03-03 09:24:38 +00001541- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.

Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001547 an ferror() call.
1548
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001549- min() and max() now support key= arguments with the same meaning as in
1550 list.sort().
1551
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001552- The peephole optimizer now performs simple constant folding in expressions:
1553 (2+3) --> (5).
1554
Raymond Hettingera422c342005-01-11 03:03:27 +00001555- set and frozenset objects can now be marshalled. SF #1098985.
1556
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001557- Bug #1077106: Poor argument checking could cause memory corruption
1558 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001559
Jeremy Hyltonab630502005-02-04 18:44:06 +00001560- The parser did not complain about future statements in illegal
1561 positions. It once again reports a syntax error if a future
1562 statement occurs after anything other than a doc string.
1563
Neil Schemenauercf52c072005-08-12 17:34:58 +00001564- Change the %s format specifier for str objects so that it returns a
1565 unicode instance if the argument is not an instance of basestring and
1566 calling __str__ on the argument returns a unicode instance.
1567
Tim Petersf4e69282006-02-27 17:15:31 +00001568- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1569 current thread state when the auto-GIL-state machinery knows about
1570 it (since the thread state is being deleted, continuing to remember it
1571 can't help, but can hurt if another thread happens to get created with
1572 the same thread id).

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001764- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1765 been renamed to have only a single underscore prefix. This was done to
1766 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001767
Nick Coghlan43832302006-04-23 17:04:07 +00001768- PEP 338: new module runpy defines a run_module function to support
1769 executing modules which provide access to source code or a code object
1770 via the PEP 302 import mechanisms.
1771
Anthony Baxter93f5b932006-04-03 08:05:07 +00001772- The email module's parsedate_tz function now sets the daylight savings
1773 flag to -1 (unknown) since it can't tell from the date whether it should

1780 in attribute values.
1781
Anthony Baxterc51ee692006-04-01 00:57:31 +00001782- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001783 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001784 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001785 module will not be built.
1786
Tim Petersc17976e2006-04-01 00:26:53 +00001787- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1788 aren't officially supported here, and trying to use them will probably
1789 raise an exception some day. But dicts have been allowed, and "mostly
1790 worked", so support for them won't go away without warning.
1791
Georg Brandl338ef7d2006-03-31 18:42:16 +00001792- Bug #1445068: getpass.getpass() can now be given an explicit stream
1793 argument to specify where to write the prompt.
1794
Georg Brandl22ec80b2006-03-31 18:25:44 +00001795- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1801 key to be used for signing the uploaded code.
1802
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001803- Queue.Queue objects now support .task_done() and .join() methods
1804 to make it easier to monitor when daemon threads have completed
1805 processing all enqueued tasks. Patch #1455676.
1806
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001807- popen2.Popen objects now preserve the command in a .cmd attribute.
1808
Thomas Hellerc61c0492006-03-22 10:09:27 +00001809- Added the ctypes ffi package.
1810
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001811- email 4.0 package now integrated. This is largely the same as the email 3.0
1812 package that was included in Python 2.3, except that PEP 8 module names are
1813 now used (e.g. mail.message instead of email.Message). The MIME classes
1814 have been moved to a subpackage (e.g. email.mime.text instead of
1815 email.MIMEText). The old names are still supported for now. Several
1816 deprecated Message methods have been removed and lots of bugs have been
1817 fixed. More details can be found in the email package documentation.
1818
Walter Dörwald40108c92006-03-27 08:15:44 +00001819- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1820 (a subclass of tuple) that provides incremental decoders and encoders
1821 (a way to use stateful codecs without the stream API). Python functions
1822 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1823 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1824 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001825
Walter Dörwald067db482006-03-15 22:17:27 +00001826- Patch #1359365: Calling next() on a closed StringIO.String object raises
1827 a ValueError instead of a StopIteration now (like file and cString.String do).
1828 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1829 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001830
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001831- A regrtest option -w was added to re-run failed tests in verbose mode.

1834 interpreter to exit.
1835
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001836- The function get_count() has been added to the gc module, and gc.collect()

1843 and helpful context managers nested() and closing().
1844

1904 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1905 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1906 Ronald L. Rivest offered this advice for Python:
1907
1908 "The consensus of researchers in this area (at least as
1909 expressed at the NIST Hash Function Workshop 10/31/05),
1910 is that SHA-256 is a good choice for the time being, but
1911 that research should continue, and other alternatives may
1912 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001913
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001914- Added a subset of Fredrik Lundh's ElementTree package. Available

2025 files to PyPI.
2026
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002027- distutils.commands.register now encodes the data as UTF-8 before posting
2028 them to PyPI.
2029
Raymond Hettinger267b8682005-03-27 10:47:39 +00002030- decimal operator and comparison methods now return NotImplemented
2031 instead of raising a TypeError when interacting with other types. This
2032 allows other classes to implement __radd__ style methods and have them
2033 work as expected.
2034
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002035- Bug #1163325: Decimal infinities failed to hash. Attempting to
2036 hash a NaN raised an InvalidOperation instead of a TypeError.
2037
Tim Petersecc6e6a2005-07-10 22:30:55 +00002038- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002039 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2040
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002041- Patch #1043890: Add extractall method to tarfile.
2042
Martin v. Löwisc72dd382005-03-04 13:50:17 +00002043- Patch #1075887: Don't require MSVC in distutils if there is nothing
2044 to build.
2045
Martin v. Löwis637431b2005-03-03 23:12:42 +00002046- Patch #1103407: Properly deal with tarfile iterators when untarring
2047 symbolic links on Windows.
2048
Tim Petersecc6e6a2005-07-10 22:30:55 +00002049- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00002050 profile.py if available.
2051
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002052- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2053
Martin v. Löwisc5574e82005-03-03 10:57:37 +00002054- Patch #1117454: Remove code to special-case cookies without values
2055 in LWPCookieJar.
2056
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00002057- Patch #1117339: Add cookielib special name tests.
2058
Martin v. Löwise869eb12005-03-03 09:46:07 +00002059- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
2060
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00002061- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
2062
Martin v. Löwisdf241532005-03-03 08:17:42 +00002063- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
2064
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002065- Patch #1104111: Alter setup.py --help and --help-commands.
2066
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002067- Patch #1121234: Properly cleanup _exit and tkerror commands.
2068
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002069- Patch #1049151: xdrlib now unpacks booleans as True or False.
2070
Raymond Hettingerbab41432005-02-05 01:31:19 +00002071- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2072
Guido van Rossumd0641422005-02-03 15:01:24 +00002073- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2074 disables recursive traversal through instance attributes, which can
2075 be exploited in various ways.
2076
Tim Peterse3547fd2005-12-16 23:13:57 +00002077- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002078 flags on the HTTP listening socket.
2079
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002080- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2081 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2082
Fred Drakefbdeaad2006-07-29 16:56:15 +00002083- Patches #893642, #1039083: add allow_none, encoding arguments to
2084 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002085
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002086- Bug #1110478: Revert os.environ.update to do putenv again.
2087
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002088- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2089
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002090- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2091
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002092- Enhancements to the csv module:
2093
2094 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002095 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002096 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002097 + Dialect parameter parsing has been re-implemented to improve error
2098 reporting.
2099 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2100 dictates.
2101 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002102 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002103 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002104 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2105 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002106 + reader now allows \r characters to be quoted (previously it only allowed
2107 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002108 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002109 + Dialect classes passed to the module are no longer instantiated by
2110 the module before being parsed (the former validation scheme required
2111 this, but the mechanism was unreliable).
2112 + The dialect registry now contains instances of the internal
2113 C-coded dialect type, rather than references to python objects.
2114 + the internal c-coded dialect type is now immutable.
2115 + register_dialect now accepts the same keyword dialect specifications
2116 as the reader and writer, allowing the user to register dialects
2117 without first creating a dialect class.
2118 + a configurable limit to the size of parsed fields has been added -
2119 previously, an unmatched quote character could result in the entire
2120 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002121 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002122 the parser field size limit (returning the former limit). The initial
2123 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002124 + A line_num attribute has been added to the reader object, which tracks
2125 the number of lines read from the source iterator. This is not
2126 the same as the number of records returned, as records can span
2127 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002128 + reader and writer objects were not being registered with the cyclic-GC.
2129 This has been fixed.
2130
Brett Cannone6539c42005-01-08 02:43:53 +00002131- _DummyThread objects in the threading module now delete self.__block that is
2132 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2133 lock primitives tend to be limited in number and thus should not be wasted on
2134 a _DummyThread object. Fixes bug #1089632.
2135
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002136- The imghdr module now detects Exif files.
2137
Raymond Hettinger6065d322004-12-20 23:51:53 +00002138- StringIO.truncate() now correctly adjusts the size attribute.
2139 (Bug #951915).
2140
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002141- locale.py now uses an updated locale alias table (built using
2142 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2143 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002144 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002145
Raymond Hettinger3557f422004-12-07 12:02:02 +00002146- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2147
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002148- the pickle module no longer accepts the deprecated None option in the
2149 args tuple returned by __reduce__().
2150
Brett Cannon84667c02004-12-07 03:25:18 +00002151- optparse now optionally imports gettext. This allows its use in setup.py.
2152
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002153- the pickle module no longer uses the deprecated bin parameter.
2154
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002155- the shelve module no longer uses the deprecated binary parameter.
2156
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002157- the pstats module no longer uses the deprecated ignore() method.
2158
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002159- the filecmp module no longer uses the deprecated use_statcache argument.
2160
Raymond Hettinger664347b2004-12-04 21:21:53 +00002161- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2162 extended or overridden by subclasses. Formerly, the subclassed method would
2163 be ignored by the rest of the module. (Bug #1078905).
2164
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002165- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002166 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002167
Walter Dörwald36733692004-12-22 12:50:50 +00002168- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2169 once when a size argument is given. This prevents a buffer overflow in the
2170 tokenizer with very long source lines.
2171
Barry Warsaw538561e2006-01-01 21:48:54 +00002172- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2173 immediately after creating the object, without any intervening
2174 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002175
Skip Montanaro05885812005-01-16 20:48:27 +00002176- The reconvert.quote function can now emit triple-quoted strings. The
2177 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002178
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002179- ``UserString.MutableString`` now supports negative indices in
2180 ``__setitem__`` and ``__delitem__``
2181
Greg Ward40407942005-03-05 02:53:17 +00002182- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2183 correctly.
2184
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002185- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2186 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2187 character even if the user has passed a size parameter to get a proper
2188 line ending. Remove the special handling of a "\r\n" that has been split
2189 between two lines.
2190
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002191- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2192 about illegal code points. The codec now supports PEP 293 style error
2193 handlers.
2194
Walter Dörwald78a78b02005-09-01 12:04:29 +00002195- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002196 from the input stream, so that the output is a byte string in the correct
2197 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002198
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002199- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2200 considering it exactly like a '*'.
2201
Walter Dörwald007f8df2005-10-09 19:42:27 +00002202- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2203 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002204
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002205- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2206
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002207- Patch #1413711: Certain patterns of differences were making difflib
2208 touch the recursion limit.
2209
Walter Dörwald58917a62006-03-31 15:26:22 +00002210- Bug #947906: An object oriented interface has been added to the calendar
2211 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002212 called as a script (e.g. via ``python -mcalendar``). Localized month and
2213 weekday names can be ouput (even if an exotic encoding is used) using
2214 special classes that use unicode.

2218
Neal Norwitz602d3392006-03-31 08:21:40 +00002219- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2220 by using -mieee gcc option.
2221
Martin v. Löwis86d66262006-02-17 08:40:11 +00002222- Patch #1432345: Make python compile on DragonFly.
2223
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002224- Build support for Win64-AMD64 was added.
2225
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002226- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2227
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002228- Patch #881820: look for openpty and forkpty also in libbsd.
2229
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002230- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2231 The zlib module is now builtin on Windows.
2232
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002233- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2234
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002235- Bug #1189330: configure did not correctly determine the necessary
2236 value of LINKCC if python was built with GCC 4.0.
2237
Trent Mick8321b422005-07-26 02:29:21 +00002238- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2239 vulnerability in zlib 1.2.1 and 1.2.2.
2240
Brett Cannon08cd5982005-04-24 22:26:38 +00002241- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2242 flags that change binary compatibility. Changes were also made to
2243 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002244 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002245
Bob Ippolitoed233462005-03-29 13:47:59 +00002246- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2247 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2248 no longer exists). This configure patch makes things right.
2249
Martin v. Löwise2713be2005-03-08 15:03:08 +00002250- Bug #1158607: Build with --disable-unicode again.
2251
Brett Cannon46d96232005-02-16 00:07:19 +00002252- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2253 defined. Discovered as a result of not being able to build on OS X.
2254
Brett Cannon516592f2004-12-07 00:42:59 +00002255- setup.py now uses the directories specified in LDFLAGS using the -L option
2256 and in CPPFLAGS using the -I option for adding library and include
2257 directories, respectively, for compiling extension modules against. This has
2258 led to the core being compiled using the values in CPPFLAGS. It also removes
2259 the need for the special-casing of both DarwinPorts and Fink for darwin since
2260 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2261 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2262 Fink, ``-I/opt/local/include`` for DarwinPorts).
2263
Brett Cannon43802422005-02-10 20:48:03 +00002264- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2265 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2266 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2267 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002269C API
2270-----
2271
Tim Petersc9d78aa2006-03-26 23:27:58 +00002272- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2273 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2274 is obtained via the ``PyObject_`` family, it must be released via the
2275 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2276 always been officially true, but when Python's small-object allocator was
2277 introduced, an attempt was made to cater to a few extension modules
2278 discovered at the time that obtained memory via ``PyObject_New`` but
2279 released it via ``PyMem_DEL``. It's years later, and if such code still
2280 exists it will fail now (probably with segfaults, but calling wrong
2281 low-level memory management functions can yield many symptoms).
2282
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002283- Added a C API for set and frozenset objects.
2284
Raymond Hettinger66517482004-12-03 11:45:13 +00002285- Removed PyRange_New().
2286
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002287- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2288 mapping argument now. This string is used as a mapping table. Byte values
2289 greater than the length of the string and 0xFFFE are treated as undefined
2290 mappings.
