106 outside of pystate.c and should not be necessary.
107
Brett Cannon19d76c52006-09-09 07:18:44 +0000108- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000126- The return tuple from str.rpartition(sep) is (tail, sep, head) where
127 head is the original string if sep was not found.
128
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000129- Bug #1520864: unpacking singleton tuples in list comprehensions and
130 generator expressions (x for x, in ... ) works again. Fixing this problem
131 required changing the .pyc magic number. This means that .pyc files
132 generated before 2.5c2 will be regenerated.

228Core and builtins
229-----------------
230
Neal Norwitz24b6f202006-09-05 04:43:56 +0000231- Fix infinite recursion when subclassing long and overriding __hash__.
232
233- Fix concatenation (+=) of long strings.
234
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000235- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000236 compared equal or unequal to a string and a UnicodeDecodeError
237 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000238
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000239 Instead, the equal (==) and unequal (!=) comparison operators will
240 now issue a UnicodeWarning and interpret the two objects as
241 unequal. The UnicodeWarning can be filtered as desired using
242 the warning framework, e.g. silenced completely, turned into an
243 exception, logged, etc.
244
245 Note that compare operators other than equal and unequal will still
246 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000247
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000248- Fix segfault when doing string formatting on subclasses of long.
249
250- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
251 with new-style classes.
252
253- Fix bug related to __len__ functions returning negative values with
254 classic classes.
255
256- Patch #1538606, Fix __index__() clipping. There were some problems
257 discovered with the API and how integers that didn't fit into Py_ssize_t
258 were handled. This patch attempts to provide enough alternatives
259 to effectively use __index__.
260
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000261- Bug #1536021: __hash__ may now return long int; the final hash
262 value is obtained by invoking hash on the long int.
263
Thomas Hellerab1049c2006-08-08 17:37:00 +0000264- Bug #1536786: buffer comparison could emit a RuntimeWarning.
265
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000266- Bug #1535165: fixed a segfault in input() and raw_input() when
267 sys.stdin is closed.
268
Thomas Heller74d36f02006-08-04 18:17:40 +0000269- On Windows, the PyErr_Warn function is now exported from
270 the Python dll again.
271
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000272- Bug #1191458: tracing over for loops now produces a line event
273 on each iteration. Fixing this problem required changing the .pyc
274 magic number. This means that .pyc files generated before 2.5c1
275 will be regenerated.
276
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000277- Bug #1333982: string/number constants were inappropriately stored
278 in the byte code and co_consts even if they were not used, ie
279 immediately popped off the stack.
280
Georg Brandle9462c72006-08-04 18:03:37 +0000281- Fixed a reference-counting problem in property().

285-------
286
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000287- Fix a bug in the ``compiler`` package that caused invalid code to be
288 generated for generator expressions.
289
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000290- The distutils version has been changed to 2.5.0. The change to
291 keep it programmatically in sync with the Python version running
292 the code (introduced in 2.5b3) has been reverted. It will continue
293 to be maintained manually as static string literal.
294
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000295- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000296 and this cannot be converted to the required C type, an exception is
297 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000298 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000299
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000300- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000301 an exception.
302
Tim Peterscbdd3502006-09-05 01:47:53 +0000303- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000304 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000305 workarounds for clocks with low resolution, to stop the code yielding
306 duplicate UUIDs.
307
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000308- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
309 before raising SystemExit, allowing IDLE to honor quit() and exit().
310
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000311- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

Georg Brandl7a1af772006-08-14 21:55:28 +0000313- Patch #1536071: trace.py should now find the full module name of a
314 file correctly even on Windows.
315
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000316- logging's atexit hook now runs even if the rest of the module has
317 already been cleaned up.
318

323
Neil Schemenauer06ded092006-08-04 16:20:30 +0000324- Fix a bug in the ``compiler`` package that caused invalid code to be

340
Thomas Heller86720042006-08-14 11:17:48 +0000341- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
342 uses the _as_parameter_ attribute when objects are passed to foreign
343 function calls. The ctypes version number was changed to 1.0.1.
344
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000345- Bug #1530559, struct.pack raises TypeError where it used to convert.
346 Passing float arguments to struct.pack when integers are expected
347 now triggers a DeprecationWarning.

Fred Drake53912162006-07-29 13:22:49 +0000392What's New in Python 2.5 beta 3?
393================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000394
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000395*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000396
397Core and builtins
398-----------------
399
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000400- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000401 returned a long (see PEP 353).
402
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000403- Bug #1515471: string.replace() accepts character buffers again.
404
Neal Norwitz07aadb12006-07-30 06:55:48 +0000405- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
406 This provides the proper warning for struct.pack().
407 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
408
Neal Norwitz0d62a062006-07-30 06:53:31 +0000409- Patch #1531113: Fix augmented assignment with yield expressions.
410 Also fix a SystemError when trying to assign to yield expressions.
411
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000412- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
413 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
414 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
415 excessive filesystem operations during imports.
416
Tim Petersbc24eee2006-07-27 01:14:53 +0000417- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
418 operations on signed longs that are formally undefined by C.
419 Unfortunately, at least one compiler now cares about that, so complicated
420 the code to make that compiler happy again.
421
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000422- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
423
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000424- Patch #1232023: Stop including current directory in search
425 path on Windows.
426
Neal Norwitze1fdb322006-07-21 05:32:28 +0000427- Fix some potential crashes found with failmalloc.
428
Neal Norwitze7563102006-07-17 01:00:16 +0000429- Fix warnings reported by Klocwork's static analysis tool.
430
Neal Norwitz84be93b2006-07-16 01:50:38 +0000431- Bug #1512814, Fix incorrect lineno's when code within a function
432 had more than 255 blank lines.
433
Georg Brandl9dceedb2006-07-12 15:31:17 +0000434- Patch #1521179: Python now accepts the standard options ``--help`` and
435 ``--version`` as well as ``/?`` on Windows.
436
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000437- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000438 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000439 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000440
Tim Peters112aad32006-07-19 00:03:19 +0000441- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000442 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000443 new ``sys._current_frames()`` returns a dictionary with one entry,
444 mapping the faux "thread id" 0 to the current frame.
445
Ronald Oussoren3075e162006-07-25 20:28:55 +0000446- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000447

Neal Norwitza1f10902006-07-12 07:28:29 +0000449Library
450-------
451
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000452- Correction of patch #1455898: In the mbcs decoder, set final=False
453 for stream decoder, but final=True for the decode function.
454
Georg Brandl07fec3a2006-08-01 18:49:24 +0000455- os.urandom no longer masks unrelated exceptions like SystemExit or
456 KeyboardInterrupt.
457
Tim Peters4643c2f2006-08-10 22:45:34 +0000458- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000459 shutil.copytree on Windows
460
Georg Brandle34ac7c2006-07-30 11:07:23 +0000461- Bug #1002398: The documentation for os.path.sameopenfile now correctly
462 refers to file descriptors, not file objects.
463
Tim Peterscbdd3502006-09-05 01:47:53 +0000464- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000465 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000466 #1513611, and probably others.
467
Georg Brandledd9b0d2006-07-29 09:33:26 +0000468- Bug #1441397: The compiler module now recognizes module and function
469 docstrings correctly as it did in Python 2.4.
470
Tim Peters6f681472006-07-27 23:44:37 +0000471- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
472 lost that tests are sorted by name before being run. This rarely
473 matters for well-written tests, but can create baffling symptoms if
474 side effects from one test to the next affect outcomes. ``DocTestFinder``
475 has been changed to sort the list of tests it returns.
476
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000477- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000478 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000479
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000480- Bug #978833: Really close underlying socket in _socketobject.close.
481
Georg Brandldb232dc2006-08-20 13:15:43 +0000482- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
483 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000484
Georg Brandlcf0c1722006-07-26 07:23:32 +0000485- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
486 to recursive calls and call it with the failing package name.
487
Martin v. Löwis0b483032006-07-25 09:53:12 +0000488- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
489
Georg Brandlc13c34c2006-07-24 14:09:56 +0000490- Patch #1515343: Fix printing of deprecated string exceptions with a
491 value in the traceback module.
492
Greg Ward48fae7a2006-07-23 16:05:51 +0000493- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
494
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000495- Patch #1524429: Use repr() instead of backticks in Tkinter again.
496
Brett Cannoncaebe222006-07-18 04:41:36 +0000497- Bug #1520914: Change time.strftime() to accept a zero for any position in its
498 argument tuple. For arguments where zero is illegal, the value is forced to
499 the minimum value that is correct. This is to support an undocumented but
500 common way people used to fill in inconsequential information in the time
501 tuple pre-2.4.
502
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000503- Patch #1220874: Update the binhex module for Mach-O.
504
Barry Warsawb110bad2006-07-21 14:51:07 +0000505- The email package has improved RFC 2231 support, specifically for
506 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
507 (name*0=<blah>) parameter continuations. This may change the types of
508 values returned from email.message.Message.get_param() and friends.
509 Specifically in some cases where non-encoded continuations were used,
510 get_param() used to return a 3-tuple of (None, None, string) whereas now it
511 will just return the string (since non-encoded continuations don't have
512 charset and language parts).
513
514 Also, whereas % values were decoded in all parameter continuations, they are
515 now only decoded in encoded parameter parts.
516
Ronald Oussoren3075e162006-07-25 20:28:55 +0000517- Bug #1517990: IDLE keybindings on MacOS X now work correctly
518
519- Bug #1517996: IDLE now longer shows the default Tk menu when a
520 path browser, class browser or debugger is the frontmost window on MacOS X
521
Barry Warsaw00decd72006-07-27 23:43:15 +0000522- Patch #1520294: Support for getset and member descriptors in types.py,
523 inspect.py, and pydoc.py. Specifically, this allows for querying the type
524 of an object against these built-in types and more importantly, for getting
525 their docstrings printed in the interactive interpreter's help() function.

530
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000531- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
532 a socket operation on a socket with a timeout, the exception will be
533 caught correctly. Previously, the exception was not caught.
534
Thomas Heller1393d6a2006-07-28 21:43:20 +0000535- Patch #1529514: The _ctypes extension is now compiled on more
536 openbsd target platforms.
537
Tim Peters9cab5932006-07-28 00:30:00 +0000538- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
539 a memory leak, affecting pickles and deep copies.
540
Tim Petersbc24eee2006-07-27 01:14:53 +0000541- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

543
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000544- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
545
Thomas Hellerce049a02006-07-14 17:51:14 +0000546- Patch #1521817: Index range checking on ctypes arrays containing
547 exactly one element enabled again. This allows iterating over these
548 arrays, without the need to check the array size before.
549
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000550- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000551 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000552 /dev/null in certain cases; this is now fixed.
553
Thomas Heller47d7a062006-07-12 08:43:47 +0000554- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
555 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000556
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000557- Because of a misspelled preprocessor symbol, ctypes was always
558 compiled without thread support; this is now fixed.
559
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000560- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
561 methods now allow their database parameter to be None as the
562 sleepycat API allows.
563
Matt Flemingec926502006-07-28 11:27:27 +0000564- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
565 bluetooth API compared with Linux and FreeBSD.
566

568-----
569
570- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
571 how long the test file should take to play. Now accepts taking 2.93 secs
572 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
573
Georg Brandl4793aa32006-07-28 18:31:39 +0000574- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
575 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
576 run via ``regrtest.py``. Now they do.

585
586- PythonLauncher now works correctly when the path to the script contains
587 characters that are treated specially by the shell (such as quotes).
588
589- Bug #1527397: PythonLauncher now launches scripts with the working directory
590 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000591 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000592 expect.

605
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000606- Bug #1501934: The scope of global variables that are locally assigned

Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000615- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
616 omit a default "error" argument for NULL pointer. This allows
617 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000618
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000619- Bug #1519018: 'as' is now validated properly in import statements.
620
Neal Norwitz28746ab2006-07-09 22:14:42 +0000621- On 64 bit systems, int literals that use less than 64 bits are
622 now ints rather than longs.
623
Neal Norwitzed657552006-07-10 00:04:44 +0000624- Bug #1512814, Fix incorrect lineno's when code at module scope
625 started after line 256.
626
Tim Peters32a83612006-07-10 21:08:24 +0000627- New function ``sys._current_frames()`` returns a dict mapping thread
628 id to topmost thread stack frame. This is for expert use, and is
629 especially useful for debugging application deadlocks. The functionality
630 was previously available in Fazal Majid's ``threadframe`` extension
631 module, but it wasn't possible to do this in a wholly threadsafe way from
632 an extension.

649
Thomas Woutersadd19112006-07-05 11:03:49 +0000650- string.Template() now correctly handles tuple-values. Previously,
651 multi-value tuples would raise an exception and single-value tuples would
652 be treated as the value they contain, instead.
653
Martin v. Löwisede77f52006-07-03 13:01:35 +0000654- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

679
Brett Cannon53ab5b72006-06-22 16:49:14 +0000680- Bug #1510580: The 'warnings' module improperly required that a Warning
681 category be either a types.ClassType and a subclass of Warning. The proper
682 check is just that it is a subclass with Warning as the documentation states.
683
Georg Brandlad29e632006-06-21 17:45:17 +0000684- The compiler module now correctly compiles the new try-except-finally
685 statement (bug #1509132).

691
Gerhard Häring762fbd32006-07-02 17:48:30 +0000692- The sqlite3 module did cut off data from the SQLite database at the first

697-----------------
698
Tim Peters112aad32006-07-19 00:03:19 +0000699- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
700 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
701 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000702
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000703- Assigning None to pointer type fields in ctypes structures possible
704 overwrote the wrong fields, this is fixed now.
705
706- Fixed a segfault in _ctypes when ctypes.wintypes were imported
707 on non-Windows platforms.
708
709- Bug #1518190: The ctypes.c_void_p constructor now accepts any
710 integer or long, without range checking.
711
712- Patch #1517790: It is now possible to use custom objects in the ctypes
713 foreign function argtypes sequence as long as they provide a from_param
714 method, no longer is it required that the object is a ctypes type.
715
716- The '_ctypes' extension module now works when Python is configured
717 with the --without-threads option.
718
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000719- Bug #1513646: os.access on Windows now correctly determines write

Martin v. Löwisd73168d2006-07-14 09:58:55 +0000733- Automate Windows build process for the Win64 SSL module.
734
Tim Peters32a83612006-07-10 21:08:24 +0000735- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000736 Previously, the slight difference could cause compilation errors of the
737 'zlib' module on systems with more than one version of zlib.
738
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000739- The MSI compileall step was fixed to also support a TARGETDIR

770Core and builtins
771-----------------
772
Georg Brandla56b9152006-06-19 06:35:54 +0000773- Patch #1507676: Error messages returned by invalid abstract object operations
774 (such as iterating over an integer) have been improved and now include the
775 type of the offending object to help with debugging.
776
Brett Cannonea3912b2006-06-13 21:46:41 +0000777- Bug #992017: A classic class that defined a __coerce__() method that returned
778 its arguments swapped would infinitely recurse and segfault the interpreter.
779
Neal Norwitz909eb122006-06-12 02:13:21 +0000780- Fix the socket tests so they can be run concurrently.
781
Neal Norwitzb9845e72006-06-12 02:11:18 +0000782- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000783 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000784
Brett Cannon22565aa2006-06-09 22:31:23 +0000785- Bug #532646: object.__call__() will continue looking for the __call__
786 attribute on objects until one without one is found. This leads to recursion
787 when you take a class and set its __call__ attribute to an instance of the
788 class. Originally fixed for classic classes, but this fix is for new-style.
789 Removes the infinite_rec_3 crasher.
790
Georg Brandl24250812006-06-09 18:45:48 +0000791- The string and unicode methods startswith() and endswith() now accept
792 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
793
Brett Cannonde3b0522006-06-08 17:00:45 +0000794- Buffer objects, at the C level, never used the char buffer
795 implementation even when the char buffer for the wrapped object was
796 explicitly requested (originally returned the read or write buffer).
797 Now a TypeError is raised if the char buffer is not present but is
798 requested.
799
Georg Brandlddbaa662006-06-04 21:56:52 +0000800- Patch #1346214: Statements like "if 0: suite" are now again optimized
801 away like they were in Python 2.4.
802
Georg Brandlb7c8f542006-05-27 12:30:25 +0000803- Builtin exceptions are now full-blown new-style classes instead of
804 instances pretending to be classes, which speeds up exception handling
805 by about 80% in comparison to 2.5a2.
806
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000807- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
808 Unicode 4.1.
809
Georg Brandlf4ef1162006-05-26 18:03:31 +0000810- Patch #921466: sys.path_importer_cache is now used to cache valid and
811 invalid file paths for the built-in import machinery which leads to
812 fewer open calls on startup.
813
Tim Peters696cf432006-05-24 21:10:40 +0000814- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
815 of-2 bases. The largest speedup is for inputs with about 1000 decimal
816 digits. Conversion from non-power-of-2 bases remains quadratic-time in
817 the number of input digits (it was and remains linear-time for bases
818 2, 4, 8, 16 and 32).
819
Tim Petersb713ec22006-05-23 18:45:30 +0000820- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
821 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
822 an integer close to ``sys.maxint``. This was repaired by patch
823 #1335972, which also gives a nice speedup.
824
Richard Jonescebbefc2006-05-23 18:28:17 +0000825- Patch #1337051: reduced size of frame objects.
826
827- PyErr_NewException now accepts a tuple of base classes as its
828 "base" parameter.
829
Richard Jones7c88dcc2006-05-23 10:37:38 +0000830- Patch #876206: function call speedup by retaining allocated frame
831 objects.
832
Georg Brandl7b90e162006-05-18 07:01:27 +0000833- Bug #1462152: file() now checks more thoroughly for invalid mode
834 strings and removes a possible "U" before passing the mode to the
835 C library function.
836
Neal Norwitz1004a532006-05-15 07:17:23 +0000837- Patch #1488312, Fix memory alignment problem on SPARC in unicode
838
Neal Norwitz373f0a72006-05-15 07:04:36 +0000839- Bug #1487966: Fix SystemError with conditional expression in assignment
840
Martin v. Löwis879768d2006-05-11 13:28:43 +0000841- WindowsError now has two error code attributes: errno, which carries
842 the error values from errno.h, and winerror, which carries the error
843 values from winerror.h. Previous versions put the winerror.h values
844 (from GetLastError()) into the errno attribute.
845
Martin v. Löwis77736712006-05-04 05:51:03 +0000846- Patch #1475845: Raise IndentationError for unexpected indent.
847
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000848- Patch #1479181: split open() and file() from being aliases for each other.
849
Tim Peters44bd9862006-06-01 13:49:23 +0000850- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
851 methods were always silently ignored by dictionaries when comparing keys.
852 They are now passed through (except when using the C API function
853 ``PyDict_GetItem()``, whose semantics did not change).
854
855- Bug #1456209: In some obscure cases it was possible for a class with a
856 custom ``__eq__()`` method to confuse dict internals when class instances
857 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
858 No, you don't have any code that did this ;-)

868 buffer and actually follow its documentation.
869
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000870- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
871
Nick Coghlanc649ec52006-05-29 12:43:05 +0000872- Patch #1478788 (modified version): The functional extension module has
873 been renamed to _functools and a functools Python wrapper module added.
874 This provides a home for additional function related utilities that are
875 not specifically about functional programming. See PEP 309.
876
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000877- Patch #1493701: performance enhancements for struct module.

885 enabled builds on Windows and systems with Posix threads support.
886
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000887- On Win32, os.listdir now supports arbitrarily-long Unicode path names
888 (up to the system limit of 32K characters).
889
890- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
891 As a result, these functions now raise WindowsError instead of OSError.
892
Tim Peters7a822da2006-05-25 21:50:17 +0000893- ``time.clock()`` on Win64 should use the high-performance Windows
894 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
895 Windows platforms).
896
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000897- Calling Tk_Init twice is refused if the first call failed as that
898 may deadlock.
899
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000900- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
901 accept it without potentially using an uninitialized pointer.
902
903- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
904 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

914 results. It could previously incorrectly return 0 in some cases.
915 Fixes SF bug 1493322 (pybsddb bug 1184012).
916
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000917- bsddb: the bsddb.dbtables Modify method now raises the proper error and
918 aborts the db transaction safely when a modifier callback fails.

Gregory P. Smith506f7b52006-06-15 08:52:32 +0000921- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000922 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000923 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
924 database calls that would previously deadlock. [SF python bug #775414]
925
Vinay Sajip28e57612006-07-01 10:45:20 +0000926- Patch #1446489: add support for the ZIP64 extensions to zipfile.

948 mime.types file for determining MIME types.
949
Georg Brandl2605ca82006-06-14 06:08:31 +0000950- Bug #1339007: Shelf objects now don't raise an exception in their
951 __del__ method when initialization failed.
952
Martin v. Löwisd8251432006-06-14 05:21:04 +0000953- Patch #1455898: The MBCS codec now supports the incremental mode for
954 double-byte encodings.
955
Tim Peters43898b42006-06-14 04:09:25 +0000956- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
957 guarantee that adjacent triples in the return list always describe
958 non-adjacent blocks. Previously, a pair of matching blocks could end
959 up being described by multiple adjacent triples that formed a partition
960 of the matching pair.
961
Greg Ward0e0c9f42006-06-11 16:24:11 +0000962- Bug #1498146: fix optparse to handle Unicode strings in option help,
963 description, and epilog.
964
Greg Wardd1c797e2006-06-11 14:42:41 +0000965- Bug #1366250: minor optparse documentation error.
966
Greg Ward7f547402006-06-11 00:40:49 +0000967- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
968 clarify docs.
969
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000970- The wsgiref package has been added to the standard library.
971
Nick Coghlan676725d2006-06-08 13:54:49 +0000972- The functions update_wrapper() and wraps() have been added to the functools
973 module. These make it easier to copy relevant metadata from the original
974 function when writing wrapper functions.
975
Tim Petersd6a9eef2006-06-05 01:48:21 +0000976- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
977 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000978
Martin v. Löwis3f767792006-06-04 19:36:28 +0000979- Patch #1359618: Speed up charmap encoder by using a trie structure
980 for lookup.
981
Tim Petersd609b1a2006-06-02 23:22:51 +0000982- The functions in the ``pprint`` module now sort dictionaries by key
983 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
984 if and only if its display required more than one line, although that
985 wasn't documented. The new behavior increases predictability; e.g.,
986 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
987
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000988- Patch #1497027: try HTTP digest auth before basic auth in urllib2

990
Georg Brandl2b330372006-05-28 20:23:12 +0000991- Patch #1496206: improve urllib2 handling of passwords with respect to
992 default HTTP and HTTPS ports.
993
George Yoshidaf3c65de2006-05-28 16:39:09 +0000994- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
995
Bob Ippolito7298f272006-05-23 18:43:47 +0000996- Patch #1281707: speed up gzip.readline.
997
Georg Brandlb89316f2006-05-17 15:51:16 +0000998- Patch #1180296: Two new functions were added to the locale module:
999 format_string() to get the effect of "format % items" but locale-aware,
1000 and currency() to format a monetary number with currency sign.
1001
Georg Brandle3a25832006-05-17 14:56:04 +00001002- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1003 and several features added, such as speed and geometry control.
1004
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001005- Patch #1488881: add support for external file objects in bz2 compressed
1006 tarfiles.
1007
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001008- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1009 stdout arguments, making it possible to redirect input and output
1010 for remote debugging.
1011
1012- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1013 a couple of issues, notably handling of long file names using the
1014 GNU LONGNAME extension.
1015
1016- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1017 new flag when ``name`` is already the name of an option flag.
1018
1019- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1020 package.
1021
1022- Patch #1472854: make the rlcompleter.Completer class usable on non-
1023 UNIX platforms.
1024
1025- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1026
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001027- Bug #1472827: correctly escape newlines and tabs in attribute values in
1028 the saxutils.XMLGenerator class.

1060
1061*Release date: 27-APR-2006*
1062
1063Core and builtins
1064-----------------
1065
Thomas Heller1b046642006-04-18 18:51:06 +00001066- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1067 by converting these apis from macros into exported functions again:
1068
1069 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1070 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1071 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1072 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1073 PyRun_String Py_CompileString
1074
Martin v. Löwis45294a92006-04-18 06:24:08 +00001075- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1076
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001077- All uses of PyStructSequence_InitType have been changed to initialize
1078 the type objects only once, even if the interpreter is initialized
1079 multiple times.
1080
Neal Norwitz61546162006-04-14 05:20:28 +00001081- Bug #1454485, array.array('u') could crash the interpreter. This was
1082 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1083 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1084
1085- Py_UNICODE is unsigned. It was always documented as unsigned, but
1086 due to a bug had a signed value in previous versions.
1087
Tim Peters3a5e8b12006-04-11 01:44:07 +00001088- Patch #837242: ``id()`` of any Python object always gives a positive
1089 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1090 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001091 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001092 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001093
Tim Peters3a5e8b12006-04-11 01:44:07 +00001094 def __hash__(self):
1095 return id(self) # WRONG
1096
1097 because a hash result must be a (short) Python int but it was always
1098 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001099 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001100 was always usable as a hash value before this patch. That's no longer
1101 necessarily so.
1102
1103- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001104 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001105 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001106 #1454844)
1107
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001108- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1109 involving generators that have paused outside of any ``try`` or ``with``
1110 blocks. (In 2.5a1, a paused generator that was part of a reference
1111 cycle could not be garbage collected, regardless of whether it was
1112 paused in a ``try`` or ``with`` block.)

1146 or exception is ignored).
1147
Nick Coghlanda2268f2006-04-24 04:37:15 +00001148- Fixed contextlib.nested to cope with exceptions being raised and
1149 caught inside exit handlers.
1150
Greg Wardab05edc2006-04-23 03:47:58 +00001151- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1152 hex, octal, or binary; add ``append_const`` action; keep going if
1153 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1154 added ``epilog`` for better help generation).
1155
Tim Peters21fbd572006-04-21 21:18:10 +00001156- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1157 called from a thread spawned as a side effect of importing a module.
1158
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001159- The pydoc module now supports documenting packages contained in
1160 .zip or .egg files.
1161
1162- The pkgutil module now has several new utility functions, such
1163 as ``walk_packages()`` to support working with packages that are either
1164 in the filesystem or zip files.
1165
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001166- The mailbox module can now modify and delete messages from

1168 K. Johnson for writing the code, and to the 2005 Google Summer of
1169 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001170
Tim Petersc7605f22006-04-17 21:12:33 +00001171- The ``__del__`` method of class ``local`` in module ``_threading_local``
1172 returned before accomplishing any of its intended cleanup.
1173
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001174- Patch #790710: Add breakpoint command lists in pdb.

Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001228- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1229 it separately and by hand. It also wasn't cleaning up its changes to
1230 the current Decimal context.
1231
Thomas Woutersabd08882006-04-26 15:53:30 +00001232- regrtest.py now has a -M option to run tests that test the new limits of
1233 containers, on 64-bit architectures. Running these tests is only sensible
1234 on 64-bit machines with more than two gigabytes of memory. The argument
1235 passed is the maximum amount of memory for the tests to use.

1244-------------
1245
Tim Petersb06d28c2006-05-12 01:57:59 +00001246- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1247
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001248- PEP 343: Added Context Types section to the library reference
1249 and attempted to bring other PEP 343 related documentation into
1250 line with the implementation and/or python-dev discussions.
1251
Tim Peters8dc73d22006-04-24 02:03:16 +00001252- Bug #1337990: clarified that ``doctest`` does not support examples
1253 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001256What's New in Python 2.5 alpha 1?
1257=================================
1258
Anthony Baxterebed3f62006-04-03 15:03:44 +00001259*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001260
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001261Core and builtins
1262-----------------
1263
Nick Coghlan43832302006-04-23 17:04:07 +00001264- PEP 338: -m command line switch now delegates to runpy.run_module
1265 allowing it to support modules in packages and zipfiles
1266
Martin v. Löwisc661b882006-04-20 04:54:23 +00001267- On Windows, .DLL is not an accepted file name extension for
1268 extension modules anymore; extensions are only found if they
1269 end in .PYD.
1270
Martin v. Löwisea62d252006-04-03 10:56:49 +00001271- Bug #1421664: sys.stderr.encoding is now set to the same value as
1272 sys.stdout.encoding.
1273
Neal Norwitz92e212f2006-04-03 04:48:37 +00001274- __import__ accepts keyword arguments.
1275
Georg Brandlccadf842006-03-31 18:54:53 +00001276- Patch #1460496: round() now accepts keyword arguments.
1277
Anthony Baxter262c00a2006-03-30 10:53:17 +00001278- Fixed bug #1459029 - unicode reprs were double-escaped.
1279
Hye-Shik Changd478f342006-03-23 12:32:36 +00001280- Patch #1396919: The system scope threads are reenabled on FreeBSD
1281 5.4 and later versions.
1282
Neal Norwitze98ccf62006-03-23 05:39:47 +00001283- Bug #1115379: Compiling a Unicode string with an encoding declaration
1284 now gives a SyntaxError.
1285
Georg Brandlabd1ff82006-03-18 07:59:59 +00001286- Previously, Python code had no easy way to access the contents of a
1287 cell object. Now, a ``cell_contents`` attribute has been added
1288 (closes patch #1170323).
1289
Tim Peterscf79aac2006-03-16 01:14:46 +00001290- Patch #1123430: Python's small-object allocator now returns an arena to
1291 the system ``free()`` when all memory within an arena becomes unused
1292 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1293 freed. Some applications will see a drop in virtual memory size now,
1294 especially long-running applications that, from time to time, temporarily
1295 use a large number of small objects. Note that when Python returns an
1296 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001297 platform C library will in turn return that memory to the operating system.
1298 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001299 appears to be effective at least on Microsoft C and gcc-based systems.
1300 Thanks to Evan Jones for hard work and patience.
1301
Georg Brandl533ff6f2006-03-08 18:09:27 +00001302- Patch #1434038: property() now uses the getter's docstring if there is
1303 no "doc" argument given. This makes it possible to legitimately use
1304 property() as a decorator to produce a read-only property.
1305
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001306- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1307 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1308 of requiring an int or long in slicing and a few other contexts, enabling
1309 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1310
Neal Norwitz995acdf2006-03-07 05:01:00 +00001311- Fixed various bugs reported by Coverity's Prevent tool.
1312
Brett Cannonbf364092006-03-01 04:25:17 +00001313- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1314 new exception base class, BaseException, which has a new message attribute.
1315 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1316 Raising a string exception now raises a DeprecationWarning.
1317
Thomas Woutersfb609f42006-02-28 16:37:25 +00001318- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1319 explicitly relative, using 'from .module import name' to mean 'from the same
1320 package as this module is in. Imports without dots still default to the
1321 old relative-then-absolute, unless 'from __future__ import
1322 absolute_import' is used.
1323
Brett Cannona7446e32006-02-27 23:39:10 +00001324- Properly check if 'warnings' raises an exception (usually when a filter set
1325 to "error" is triggered) when raising a warning for raising string
1326 exceptions.
1327
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001328- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001329 The name was removed from Include/code.h.
1330
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001331- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001332
Guido van Rossum1968ad32006-02-25 22:38:04 +00001333- Patch 1433928:
1334 - The copy module now "copies" function objects (as atomic objects).
1335 - dict.__getitem__ now looks for a __missing__ hook before raising
1336 KeyError.
1337
Tim Peters84ef21c2006-02-28 20:39:06 +00001338- PEP 343: with statement implemented. Needs ``from __future__ import
1339 with_statement``. Use of 'with' as a variable will generate a warning.
1340 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001341 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001342 The following objects have __context__ methods:
1343 - The built-in file type.
1344 - The thread.LockType type.
1345 - The following types defined by the threading module:
1346 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1347 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001348
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001349- Fix the encodings package codec search function to only search
1350 inside its own package. Fixes problem reported in patch #1433198.
1351
1352 Note: Codec packages should implement and register their own
1353 codec search function. PEP 100 has the details.
1354
Tim Peters9ea89d22006-06-04 03:26:02 +00001355- PEP 353: Using ``Py_ssize_t`` as the index type.
1356
1357- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1358 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1359 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1360 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1361 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001362
Neal Norwitzfc76d632006-01-10 06:03:13 +00001363- Patch #1400181, fix unicode string formatting to not use the locale.
1364 This is how string objects work. u'%f' could use , instead of .
1365 for the decimal point. Now both strings and unicode always use periods.
1366
Neal Norwitz671b9e32006-01-09 07:07:12 +00001367- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1368 configure would break checking curses.h.
1369
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001370- Bug #959576: The pwd module is now builtin. This allows Python to be
1371 built on UNIX platforms without $HOME set.
1372
Neal Norwitzc10978f2005-12-19 06:07:16 +00001373- Bug #1072182, fix some potential problems if characters are signed.
1374
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001375- Bug #889500, fix line number on SyntaxWarning for global declarations.
1376
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001377- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1378
Neal Norwitze7214a12005-12-18 05:03:17 +00001379- Support for converting hex strings to floats no longer works.
1380 This was not portable. float('0x3') now raises a ValueError.
1381
Barry Warsaw2a38a862005-12-18 01:27:35 +00001382- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001383 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001384 is now displayed in interactive prompt banner.
1385
Georg Brandlfa166682005-12-17 21:45:17 +00001386- Implementation of PEP 341 - Unification of try/except and try/finally.
1387 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001388 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001389
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001390- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1391 now encodes backslash correctly.
1392
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001393- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1394
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001395- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001396 and long longs.
1397
Neal Norwitz67715f02005-11-09 06:59:35 +00001398- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001399 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001400 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001401
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001402- Replaced most Unicode charmap codecs with new ones using the
1403 new Unicode translate string feature in the builtin charmap
1404 codec; the codecs were created from the mapping tables available
1405 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1406 encodings now include a mapping for the Apple logo)
1407
Tim Peterse3547fd2005-12-16 23:13:57 +00001408- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001409
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001410- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001411
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001412- A new AST parser implementation was completed. The abstract
1413 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001414 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001415
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001416- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001417 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1418
Neal Norwitz708e51a2005-10-03 04:48:15 +00001419- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1420
Neal Norwitz11bd1192005-10-03 00:54:56 +00001421- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1422 Provide a warning when a directory is passed on the command line.
1423
Neal Norwitz40d37812005-10-02 01:48:49 +00001424- Fix segfault with invalid coding.
1425
1426- SF bug #772896: unknown encoding results in MemoryError.
1427
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001428- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001429 supported a __len__() method which evaluated to False when the iterator
1430 was empty.
1431
Guido van Rossum630db602005-09-20 18:49:54 +00001432- On 64-bit platforms, when __len__() returns a value that cannot be
1433 represented as a C int, raise OverflowError.
1434
Skip Montanarof8948ca2005-09-19 03:54:46 +00001435- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001436 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001437
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001438- SF bug #893549: parsing keyword arguments was broken with a few format
1439 codes.
1440
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001441- Changes donated by Elemental Security to make it work on AIX 5.3
1442 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1443 bug #105470: test_pwd fails on 64bit system (Opteron).
1444
Guido van Rossum539c6622005-09-14 17:49:54 +00001445- Changes donated by Elemental Security to make it work on HP-UX 11 on
1446 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1447
Georg Brandl4550b8d2005-08-26 06:43:52 +00001448- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001449 (fixes bug #1119418).
1450
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001451- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1452
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001453- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1454 exceptions that cause a function to exit.
1455
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001456- The implementation of set() and frozenset() was revised to use its
1457 own internal data structure. Memory consumption is reduced by 1/3
1458 and there are modest speed-ups as well. The API is unchanged.
1459
Tim Petersde7990b2005-07-17 23:45:23 +00001460- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1461
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001462- SF bug #1229429: PyObject_CallMethod failed to decrement some
1463 reference counts in some error exit cases.
1464
Tim Petersecc6e6a2005-07-10 22:30:55 +00001465- SF bug #1185883: Python's small-object memory allocator took over
1466 a block managed by the platform C library whenever a realloc specified
1467 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001468 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001469 portable way to copy data from the C-managed block into Python's
1470 small-object space without risking a memory fault. Python's small-object
1471 realloc now leaves such blocks under the control of the platform C
1472 realloc.
1473
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001474- SF bug #1232517: An overflow error was not detected properly when
1475 attempting to convert a large float to an int in os.utime().
1476
Raymond Hettinger3296e692005-06-29 23:29:56 +00001477- SF bug #1224347: hex longs now print with lowercase letters just
1478 like their int counterparts.
1479
Michael W. Hudson188d4362005-06-20 16:52:57 +00001480- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1481 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1482 interpreter states; back out that fix and do a better job (see
1483 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1484 for a longer write-up of the problem).
1485
Michael W. Hudsondf888462005-06-03 14:41:55 +00001486- SF patch #1180995: marshal now uses a binary format by default when
1487 serializing floats.
1488
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001489- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1490 the routines that promise to produce IEEE 754 binary representations
1491 of floats now simply copy bytes around.
1492
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001493- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1494 278.
1495
Brett Cannonc3647ac2005-04-26 03:45:26 +00001496- patch #1109424: int, long, float, complex, and unicode now check for the
1497 proper magic slot for type conversions when subclassed. Previously the
1498 magic slot was ignored during conversion. Semantics now match the way
1499 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001500 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001501 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001502 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001503
Barry Warsawc8d907c2005-04-19 23:43:40 +00001504- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1505 NULL, now raise an AttributeError when attempting to set or delete the
1506 attribute. Previously a TypeError was raised, but this was inconsistent
1507 with the equivalent pure-Python implementation.
1508
Michael W. Hudson774479c2005-04-18 08:46:17 +00001509- It is now safe to call PyGILState_Release() before
1510 PyEval_InitThreads() (note that if there is reason to believe there
1511 are multiple threads around you still must call PyEval_InitThreads()
1512 before using the Python API; this fix is for extension modules that
1513 have no way of knowing if Python is multi-threaded yet).
1514
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001515- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1516 disabled caused a crash.
1517
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001518- Bug #1165306: instancemethod_new allowed the creation of a method
1519 with im_class == im_self == NULL, which caused a crash when called.
1520
Tim Petersecc6e6a2005-07-10 22:30:55 +00001521- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001522 fixes the crash seen in bug #1165761
1523
Raymond Hettinger96229b12005-03-11 06:49:40 +00001524- Added two new builtins, any() and all().
1525
Brett Cannon409d8f22005-03-05 06:47:57 +00001526- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001527 (e.g., ``class C(): pass`` is no longer a syntax error).
1528 Patch #1176012 added support to the 'parser' module and 'compiler' package
1529 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001530

1534 returning None.
1535
Tim Petersecc6e6a2005-07-10 22:30:55 +00001536- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001537 ('\') with a specific error message.
1538
Martin v. Löwisff232d72005-03-03 09:24:38 +00001539- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1540
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001541- Bug #1124295: the __name__ attribute of file objects was

1543
Tim Petersecc6e6a2005-07-10 22:30:55 +00001544- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001545 an ferror() call.
1546
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001547- min() and max() now support key= arguments with the same meaning as in
1548 list.sort().
1549
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001550- The peephole optimizer now performs simple constant folding in expressions:
1551 (2+3) --> (5).
1552
Raymond Hettingera422c342005-01-11 03:03:27 +00001553- set and frozenset objects can now be marshalled. SF #1098985.
1554
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001555- Bug #1077106: Poor argument checking could cause memory corruption
1556 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001557
Jeremy Hyltonab630502005-02-04 18:44:06 +00001558- The parser did not complain about future statements in illegal
1559 positions. It once again reports a syntax error if a future
1560 statement occurs after anything other than a doc string.
1561
Neil Schemenauercf52c072005-08-12 17:34:58 +00001562- Change the %s format specifier for str objects so that it returns a
1563 unicode instance if the argument is not an instance of basestring and
1564 calling __str__ on the argument returns a unicode instance.
1565
Tim Petersf4e69282006-02-27 17:15:31 +00001566- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1567 current thread state when the auto-GIL-state machinery knows about
1568 it (since the thread state is being deleted, continuing to remember it
1569 can't help, but can hurt if another thread happens to get created with
1570 the same thread id).

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001762- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1763 been renamed to have only a single underscore prefix. This was done to
1764 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001765
Nick Coghlan43832302006-04-23 17:04:07 +00001766- PEP 338: new module runpy defines a run_module function to support
1767 executing modules which provide access to source code or a code object
1768 via the PEP 302 import mechanisms.
1769
Anthony Baxter93f5b932006-04-03 08:05:07 +00001770- The email module's parsedate_tz function now sets the daylight savings
1771 flag to -1 (unknown) since it can't tell from the date whether it should

1778 in attribute values.
1779
Anthony Baxterc51ee692006-04-01 00:57:31 +00001780- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001781 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001782 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001783 module will not be built.
1784
Tim Petersc17976e2006-04-01 00:26:53 +00001785- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1786 aren't officially supported here, and trying to use them will probably
1787 raise an exception some day. But dicts have been allowed, and "mostly
1788 worked", so support for them won't go away without warning.
1789
Georg Brandl338ef7d2006-03-31 18:42:16 +00001790- Bug #1445068: getpass.getpass() can now be given an explicit stream
1791 argument to specify where to write the prompt.
1792

1799 key to be used for signing the uploaded code.
1800
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001801- Queue.Queue objects now support .task_done() and .join() methods
1802 to make it easier to monitor when daemon threads have completed
1803 processing all enqueued tasks. Patch #1455676.
1804
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001805- popen2.Popen objects now preserve the command in a .cmd attribute.
1806
Thomas Hellerc61c0492006-03-22 10:09:27 +00001807- Added the ctypes ffi package.
1808
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001809- email 4.0 package now integrated. This is largely the same as the email 3.0
1810 package that was included in Python 2.3, except that PEP 8 module names are
1811 now used (e.g. mail.message instead of email.Message). The MIME classes
1812 have been moved to a subpackage (e.g. email.mime.text instead of
1813 email.MIMEText). The old names are still supported for now. Several
1814 deprecated Message methods have been removed and lots of bugs have been
1815 fixed. More details can be found in the email package documentation.
1816
Walter Dörwald40108c92006-03-27 08:15:44 +00001817- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1818 (a subclass of tuple) that provides incremental decoders and encoders
1819 (a way to use stateful codecs without the stream API). Python functions
1820 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1821 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1822 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001823
Walter Dörwald067db482006-03-15 22:17:27 +00001824- Patch #1359365: Calling next() on a closed StringIO.String object raises
1825 a ValueError instead of a StopIteration now (like file and cString.String do).
1826 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1827 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001828
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001829- A regrtest option -w was added to re-run failed tests in verbose mode.

1832 interpreter to exit.
1833
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001834- The function get_count() has been added to the gc module, and gc.collect()

1841 and helpful context managers nested() and closing().
1842

1902 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1903 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1904 Ronald L. Rivest offered this advice for Python:
1905
1906 "The consensus of researchers in this area (at least as
1907 expressed at the NIST Hash Function Workshop 10/31/05),
1908 is that SHA-256 is a good choice for the time being, but
1909 that research should continue, and other alternatives may
1910 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001911
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001912- Added a subset of Fredrik Lundh's ElementTree package. Available

2023 files to PyPI.
2024
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002025- distutils.commands.register now encodes the data as UTF-8 before posting
2026 them to PyPI.
2027
Raymond Hettinger267b8682005-03-27 10:47:39 +00002028- decimal operator and comparison methods now return NotImplemented
2029 instead of raising a TypeError when interacting with other types. This
2030 allows other classes to implement __radd__ style methods and have them
2031 work as expected.
2032
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002033- Bug #1163325: Decimal infinities failed to hash. Attempting to
2034 hash a NaN raised an InvalidOperation instead of a TypeError.
2035
Tim Petersecc6e6a2005-07-10 22:30:55 +00002036- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002037 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2038
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002039- Patch #1043890: Add extractall method to tarfile.
2040
Martin v. Löwisc72dd382005-03-04 13:50:17 +00002041- Patch #1075887: Don't require MSVC in distutils if there is nothing
2042 to build.
2043
Martin v. Löwis637431b2005-03-03 23:12:42 +00002044- Patch #1103407: Properly deal with tarfile iterators when untarring
2045 symbolic links on Windows.
2046
Tim Petersecc6e6a2005-07-10 22:30:55 +00002047- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00002048 profile.py if available.
2049
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002050- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2051
Martin v. Löwisc5574e82005-03-03 10:57:37 +00002052- Patch #1117454: Remove code to special-case cookies without values
2053 in LWPCookieJar.
2054
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00002055- Patch #1117339: Add cookielib special name tests.
2056
Martin v. Löwise869eb12005-03-03 09:46:07 +00002057- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
2058
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00002059- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
2060
Martin v. Löwisdf241532005-03-03 08:17:42 +00002061- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
2062
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002063- Patch #1104111: Alter setup.py --help and --help-commands.
2064
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002065- Patch #1121234: Properly cleanup _exit and tkerror commands.
2066
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002067- Patch #1049151: xdrlib now unpacks booleans as True or False.
2068
Raymond Hettingerbab41432005-02-05 01:31:19 +00002069- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2070
Guido van Rossumd0641422005-02-03 15:01:24 +00002071- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2072 disables recursive traversal through instance attributes, which can
2073 be exploited in various ways.
2074
Tim Peterse3547fd2005-12-16 23:13:57 +00002075- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002076 flags on the HTTP listening socket.
2077
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002078- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2079 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2080
Fred Drakefbdeaad2006-07-29 16:56:15 +00002081- Patches #893642, #1039083: add allow_none, encoding arguments to
2082 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002083
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002084- Bug #1110478: Revert os.environ.update to do putenv again.
2085
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002086- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2087
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002088- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2089
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002090- Enhancements to the csv module:
2091
2092 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002093 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002094 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002095 + Dialect parameter parsing has been re-implemented to improve error
2096 reporting.
2097 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2098 dictates.
2099 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002100 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002101 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002102 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2103 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002104 + reader now allows \r characters to be quoted (previously it only allowed
2105 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002106 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002107 + Dialect classes passed to the module are no longer instantiated by
2108 the module before being parsed (the former validation scheme required
2109 this, but the mechanism was unreliable).
2110 + The dialect registry now contains instances of the internal
2111 C-coded dialect type, rather than references to python objects.
2112 + the internal c-coded dialect type is now immutable.
2113 + register_dialect now accepts the same keyword dialect specifications
2114 as the reader and writer, allowing the user to register dialects
2115 without first creating a dialect class.
2116 + a configurable limit to the size of parsed fields has been added -
2117 previously, an unmatched quote character could result in the entire
2118 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002119 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002120 the parser field size limit (returning the former limit). The initial
2121 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002122 + A line_num attribute has been added to the reader object, which tracks
2123 the number of lines read from the source iterator. This is not
2124 the same as the number of records returned, as records can span
2125 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002126 + reader and writer objects were not being registered with the cyclic-GC.
2127 This has been fixed.
2128
Brett Cannone6539c42005-01-08 02:43:53 +00002129- _DummyThread objects in the threading module now delete self.__block that is
2130 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2131 lock primitives tend to be limited in number and thus should not be wasted on
2132 a _DummyThread object. Fixes bug #1089632.
2133
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002134- The imghdr module now detects Exif files.
2135
Raymond Hettinger6065d322004-12-20 23:51:53 +00002136- StringIO.truncate() now correctly adjusts the size attribute.
2137 (Bug #951915).
2138
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002139- locale.py now uses an updated locale alias table (built using
2140 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2141 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002142 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002143
Raymond Hettinger3557f422004-12-07 12:02:02 +00002144- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2145
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002146- the pickle module no longer accepts the deprecated None option in the
2147 args tuple returned by __reduce__().
2148
Brett Cannon84667c02004-12-07 03:25:18 +00002149- optparse now optionally imports gettext. This allows its use in setup.py.
2150
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002151- the pickle module no longer uses the deprecated bin parameter.
2152
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002153- the shelve module no longer uses the deprecated binary parameter.
2154
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002155- the pstats module no longer uses the deprecated ignore() method.
2156
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002157- the filecmp module no longer uses the deprecated use_statcache argument.
2158
Raymond Hettinger664347b2004-12-04 21:21:53 +00002159- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2160 extended or overridden by subclasses. Formerly, the subclassed method would
2161 be ignored by the rest of the module. (Bug #1078905).
2162
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002163- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002164 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002165
Walter Dörwald36733692004-12-22 12:50:50 +00002166- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2167 once when a size argument is given. This prevents a buffer overflow in the
2168 tokenizer with very long source lines.
2169
Barry Warsaw538561e2006-01-01 21:48:54 +00002170- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2171 immediately after creating the object, without any intervening
2172 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002173
Skip Montanaro05885812005-01-16 20:48:27 +00002174- The reconvert.quote function can now emit triple-quoted strings. The
2175 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002176
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002177- ``UserString.MutableString`` now supports negative indices in
2178 ``__setitem__`` and ``__delitem__``
2179
Greg Ward40407942005-03-05 02:53:17 +00002180- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2181 correctly.
2182
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002183- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2184 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2185 character even if the user has passed a size parameter to get a proper
2186 line ending. Remove the special handling of a "\r\n" that has been split
2187 between two lines.
2188
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002189- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2190 about illegal code points. The codec now supports PEP 293 style error
2191 handlers.
2192
Walter Dörwald78a78b02005-09-01 12:04:29 +00002193- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002194 from the input stream, so that the output is a byte string in the correct
2195 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002196
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002197- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2198 considering it exactly like a '*'.
2199
Walter Dörwald007f8df2005-10-09 19:42:27 +00002200- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2201 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002202
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002203- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2204
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002205- Patch #1413711: Certain patterns of differences were making difflib
2206 touch the recursion limit.
2207
Walter Dörwald58917a62006-03-31 15:26:22 +00002208- Bug #947906: An object oriented interface has been added to the calendar
2209 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002210 called as a script (e.g. via ``python -mcalendar``). Localized month and
2211 weekday names can be ouput (even if an exotic encoding is used) using
2212 special classes that use unicode.

2216
Neal Norwitz602d3392006-03-31 08:21:40 +00002217- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2218 by using -mieee gcc option.
2219
Martin v. Löwis86d66262006-02-17 08:40:11 +00002220- Patch #1432345: Make python compile on DragonFly.
2221
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002222- Build support for Win64-AMD64 was added.
2223
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002224- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2225
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002226- Patch #881820: look for openpty and forkpty also in libbsd.
2227
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002228- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2229 The zlib module is now builtin on Windows.
2230
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002231- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2232
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002233- Bug #1189330: configure did not correctly determine the necessary
2234 value of LINKCC if python was built with GCC 4.0.
2235
Trent Mick8321b422005-07-26 02:29:21 +00002236- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2237 vulnerability in zlib 1.2.1 and 1.2.2.
2238
Brett Cannon08cd5982005-04-24 22:26:38 +00002239- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2240 flags that change binary compatibility. Changes were also made to
2241 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002242 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002243
Bob Ippolitoed233462005-03-29 13:47:59 +00002244- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2245 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2246 no longer exists). This configure patch makes things right.
2247
Martin v. Löwise2713be2005-03-08 15:03:08 +00002248- Bug #1158607: Build with --disable-unicode again.
2249
Brett Cannon46d96232005-02-16 00:07:19 +00002250- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2251 defined. Discovered as a result of not being able to build on OS X.
2252
Brett Cannon516592f2004-12-07 00:42:59 +00002253- setup.py now uses the directories specified in LDFLAGS using the -L option
2254 and in CPPFLAGS using the -I option for adding library and include
2255 directories, respectively, for compiling extension modules against. This has
2256 led to the core being compiled using the values in CPPFLAGS. It also removes
2257 the need for the special-casing of both DarwinPorts and Fink for darwin since
2258 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2259 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2260 Fink, ``-I/opt/local/include`` for DarwinPorts).
2261
Brett Cannon43802422005-02-10 20:48:03 +00002262- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2263 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2264 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2265 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002267C API
2268-----
2269
Tim Petersc9d78aa2006-03-26 23:27:58 +00002270- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2271 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2272 is obtained via the ``PyObject_`` family, it must be released via the
2273 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2274 always been officially true, but when Python's small-object allocator was
2275 introduced, an attempt was made to cater to a few extension modules
2276 discovered at the time that obtained memory via ``PyObject_New`` but
2277 released it via ``PyMem_DEL``. It's years later, and if such code still
2278 exists it will fail now (probably with segfaults, but calling wrong
2279 low-level memory management functions can yield many symptoms).
2280
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002281- Added a C API for set and frozenset objects.
2282
Raymond Hettinger66517482004-12-03 11:45:13 +00002283- Removed PyRange_New().
2284
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002285- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2286 mapping argument now. This string is used as a mapping table. Byte values
2287 greater than the length of the string and 0xFFFE are treated as undefined
2288 mappings.
