21
22- Fix some leftovers from the conversion from int to Py_ssize_t
23 (relevant to strings and sequences of more than 2**31 items).
24
25- A number of places, including integer negation and absolute value,

114-----------------
115
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000116- Make _PyGILState_NoteThreadState() static, it was not used anywhere
117 outside of pystate.c and should not be necessary.
118
Brett Cannon19d76c52006-09-09 07:18:44 +0000119- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
120 allows calling unicode() on exceptions classes directly to succeed.
121
Georg Brandlecab6232006-09-06 06:47:02 +0000122- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

136
Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000137- The return tuple from str.rpartition(sep) is (tail, sep, head) where
138 head is the original string if sep was not found.
139
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000140- Bug #1520864: unpacking singleton tuples in list comprehensions and
141 generator expressions (x for x, in ... ) works again. Fixing this problem
142 required changing the .pyc magic number. This means that .pyc files
143 generated before 2.5c2 will be regenerated.

Guido van Rossumc69ac252006-08-10 18:09:25 +0000236What's New in Python 2.5 release candidate 1?

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000238

241Core and builtins
242-----------------
243
Neal Norwitz24b6f202006-09-05 04:43:56 +0000244- Fix infinite recursion when subclassing long and overriding __hash__.
245
246- Fix concatenation (+=) of long strings.
247
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000248- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000249 compared equal or unequal to a string and a UnicodeDecodeError
250 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000251
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000252 Instead, the equal (==) and unequal (!=) comparison operators will
253 now issue a UnicodeWarning and interpret the two objects as
254 unequal. The UnicodeWarning can be filtered as desired using
255 the warning framework, e.g. silenced completely, turned into an
256 exception, logged, etc.
257
258 Note that compare operators other than equal and unequal will still
259 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000260
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000261- Fix segfault when doing string formatting on subclasses of long.
262
263- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
264 with new-style classes.
265
266- Fix bug related to __len__ functions returning negative values with
267 classic classes.
268
269- Patch #1538606, Fix __index__() clipping. There were some problems
270 discovered with the API and how integers that didn't fit into Py_ssize_t
271 were handled. This patch attempts to provide enough alternatives
272 to effectively use __index__.
273
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000274- Bug #1536021: __hash__ may now return long int; the final hash
275 value is obtained by invoking hash on the long int.
276
Thomas Hellerab1049c2006-08-08 17:37:00 +0000277- Bug #1536786: buffer comparison could emit a RuntimeWarning.
278
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000279- Bug #1535165: fixed a segfault in input() and raw_input() when
280 sys.stdin is closed.
281
Thomas Heller74d36f02006-08-04 18:17:40 +0000282- On Windows, the PyErr_Warn function is now exported from
283 the Python dll again.
284
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000285- Bug #1191458: tracing over for loops now produces a line event
286 on each iteration. Fixing this problem required changing the .pyc
287 magic number. This means that .pyc files generated before 2.5c1
288 will be regenerated.
289
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000290- Bug #1333982: string/number constants were inappropriately stored
291 in the byte code and co_consts even if they were not used, ie
292 immediately popped off the stack.
293
Georg Brandle9462c72006-08-04 18:03:37 +0000294- Fixed a reference-counting problem in property().

298-------
299
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000300- Fix a bug in the ``compiler`` package that caused invalid code to be
301 generated for generator expressions.
302
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000303- The distutils version has been changed to 2.5.0. The change to
304 keep it programmatically in sync with the Python version running
305 the code (introduced in 2.5b3) has been reverted. It will continue
306 to be maintained manually as static string literal.
307
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000308- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000309 and this cannot be converted to the required C type, an exception is
310 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000311 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000312
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000313- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000314 an exception.
315
Tim Peterscbdd3502006-09-05 01:47:53 +0000316- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000317 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000318 workarounds for clocks with low resolution, to stop the code yielding
319 duplicate UUIDs.
320
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000321- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
322 before raising SystemExit, allowing IDLE to honor quit() and exit().
323
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000324- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

Georg Brandl7a1af772006-08-14 21:55:28 +0000326- Patch #1536071: trace.py should now find the full module name of a
327 file correctly even on Windows.
328
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000329- logging's atexit hook now runs even if the rest of the module has
330 already been cleaned up.
331

335 str(exception) raised an exception.
336
Neil Schemenauer06ded092006-08-04 16:20:30 +0000337- Fix a bug in the ``compiler`` package that caused invalid code to be
338 generated for nested functions.

349 raises the correct exceptions.
350
Thomas Heller1ce433e2006-08-14 16:20:04 +0000351- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
352 '-no-stack-protector' compiler flag for OpenBSD has been removed.
353
Thomas Heller86720042006-08-14 11:17:48 +0000354- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
355 uses the _as_parameter_ attribute when objects are passed to foreign
356 function calls. The ctypes version number was changed to 1.0.1.
357
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000358- Bug #1530559, struct.pack raises TypeError where it used to convert.
359 Passing float arguments to struct.pack when integers are expected
360 now triggers a DeprecationWarning.

Fred Drake53912162006-07-29 13:22:49 +0000405What's New in Python 2.5 beta 3?
406================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000407
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000408*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000409
410Core and builtins
411-----------------
412
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000413- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000414 returned a long (see PEP 353).
415
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000416- Bug #1515471: string.replace() accepts character buffers again.
417
Neal Norwitz07aadb12006-07-30 06:55:48 +0000418- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
419 This provides the proper warning for struct.pack().
420 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
421
Neal Norwitz0d62a062006-07-30 06:53:31 +0000422- Patch #1531113: Fix augmented assignment with yield expressions.
423 Also fix a SystemError when trying to assign to yield expressions.
424
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000425- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
426 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
427 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
428 excessive filesystem operations during imports.
429
Tim Petersbc24eee2006-07-27 01:14:53 +0000430- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
431 operations on signed longs that are formally undefined by C.
432 Unfortunately, at least one compiler now cares about that, so complicated
433 the code to make that compiler happy again.
434
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000435- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
436
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000437- Patch #1232023: Stop including current directory in search
438 path on Windows.
439
Neal Norwitze1fdb322006-07-21 05:32:28 +0000440- Fix some potential crashes found with failmalloc.
441
Neal Norwitze7563102006-07-17 01:00:16 +0000442- Fix warnings reported by Klocwork's static analysis tool.
443
Neal Norwitz84be93b2006-07-16 01:50:38 +0000444- Bug #1512814, Fix incorrect lineno's when code within a function
445 had more than 255 blank lines.
446
Georg Brandl9dceedb2006-07-12 15:31:17 +0000447- Patch #1521179: Python now accepts the standard options ``--help`` and
448 ``--version`` as well as ``/?`` on Windows.
449
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000450- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000451 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000452 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000453
Tim Peters112aad32006-07-19 00:03:19 +0000454- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000455 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000456 new ``sys._current_frames()`` returns a dictionary with one entry,
457 mapping the faux "thread id" 0 to the current frame.
458
Ronald Oussoren3075e162006-07-25 20:28:55 +0000459- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000460
Ronald Oussoren3075e162006-07-25 20:28:55 +0000461
Neal Norwitza1f10902006-07-12 07:28:29 +0000462Library
463-------
464
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000465- Correction of patch #1455898: In the mbcs decoder, set final=False
466 for stream decoder, but final=True for the decode function.
467
Georg Brandl07fec3a2006-08-01 18:49:24 +0000468- os.urandom no longer masks unrelated exceptions like SystemExit or
469 KeyboardInterrupt.
470
Tim Peters4643c2f2006-08-10 22:45:34 +0000471- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000472 shutil.copytree on Windows
473
Georg Brandle34ac7c2006-07-30 11:07:23 +0000474- Bug #1002398: The documentation for os.path.sameopenfile now correctly
475 refers to file descriptors, not file objects.
476
Tim Peterscbdd3502006-09-05 01:47:53 +0000477- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000478 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000479 #1513611, and probably others.
480
Georg Brandledd9b0d2006-07-29 09:33:26 +0000481- Bug #1441397: The compiler module now recognizes module and function
482 docstrings correctly as it did in Python 2.4.
483
Tim Peters6f681472006-07-27 23:44:37 +0000484- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
485 lost that tests are sorted by name before being run. This rarely
486 matters for well-written tests, but can create baffling symptoms if
487 side effects from one test to the next affect outcomes. ``DocTestFinder``
488 has been changed to sort the list of tests it returns.
489
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000490- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000491 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000492
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000493- Bug #978833: Really close underlying socket in _socketobject.close.
494
Georg Brandldb232dc2006-08-20 13:15:43 +0000495- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
496 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000497
Georg Brandlcf0c1722006-07-26 07:23:32 +0000498- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
499 to recursive calls and call it with the failing package name.
500
Martin v. Löwis0b483032006-07-25 09:53:12 +0000501- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
502
Georg Brandlc13c34c2006-07-24 14:09:56 +0000503- Patch #1515343: Fix printing of deprecated string exceptions with a
504 value in the traceback module.
505
Greg Ward48fae7a2006-07-23 16:05:51 +0000506- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
507
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000508- Patch #1524429: Use repr() instead of backticks in Tkinter again.
509
Brett Cannoncaebe222006-07-18 04:41:36 +0000510- Bug #1520914: Change time.strftime() to accept a zero for any position in its
511 argument tuple. For arguments where zero is illegal, the value is forced to
512 the minimum value that is correct. This is to support an undocumented but
513 common way people used to fill in inconsequential information in the time
514 tuple pre-2.4.
515
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000516- Patch #1220874: Update the binhex module for Mach-O.
517
Barry Warsawb110bad2006-07-21 14:51:07 +0000518- The email package has improved RFC 2231 support, specifically for
519 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
520 (name*0=<blah>) parameter continuations. This may change the types of
521 values returned from email.message.Message.get_param() and friends.
522 Specifically in some cases where non-encoded continuations were used,
523 get_param() used to return a 3-tuple of (None, None, string) whereas now it
524 will just return the string (since non-encoded continuations don't have
525 charset and language parts).
526
527 Also, whereas % values were decoded in all parameter continuations, they are
528 now only decoded in encoded parameter parts.
529
Ronald Oussoren3075e162006-07-25 20:28:55 +0000530- Bug #1517990: IDLE keybindings on MacOS X now work correctly
531
532- Bug #1517996: IDLE now longer shows the default Tk menu when a
533 path browser, class browser or debugger is the frontmost window on MacOS X
534
Barry Warsaw00decd72006-07-27 23:43:15 +0000535- Patch #1520294: Support for getset and member descriptors in types.py,
536 inspect.py, and pydoc.py. Specifically, this allows for querying the type
537 of an object against these built-in types and more importantly, for getting
538 their docstrings printed in the interactive interpreter's help() function.

543
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000544- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
545 a socket operation on a socket with a timeout, the exception will be
546 caught correctly. Previously, the exception was not caught.
547
Thomas Heller1393d6a2006-07-28 21:43:20 +0000548- Patch #1529514: The _ctypes extension is now compiled on more
549 openbsd target platforms.
550
Tim Peters9cab5932006-07-28 00:30:00 +0000551- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
552 a memory leak, affecting pickles and deep copies.
553
Tim Petersbc24eee2006-07-27 01:14:53 +0000554- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

556
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000557- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
558
Thomas Hellerce049a02006-07-14 17:51:14 +0000559- Patch #1521817: Index range checking on ctypes arrays containing
560 exactly one element enabled again. This allows iterating over these
561 arrays, without the need to check the array size before.
562
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000563- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000564 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000565 /dev/null in certain cases; this is now fixed.
566
Thomas Heller47d7a062006-07-12 08:43:47 +0000567- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
568 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000569
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000570- Because of a misspelled preprocessor symbol, ctypes was always
571 compiled without thread support; this is now fixed.
572
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000573- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
574 methods now allow their database parameter to be None as the
575 sleepycat API allows.
576
Matt Flemingec926502006-07-28 11:27:27 +0000577- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
578 bluetooth API compared with Linux and FreeBSD.
579

581-----
582
583- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
584 how long the test file should take to play. Now accepts taking 2.93 secs
585 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
586
Georg Brandl4793aa32006-07-28 18:31:39 +0000587- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
588 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
589 run via ``regrtest.py``. Now they do.

599- PythonLauncher now works correctly when the path to the script contains
600 characters that are treated specially by the shell (such as quotes).
601
602- Bug #1527397: PythonLauncher now launches scripts with the working directory
603 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000604 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000605 expect.

Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000616- Bug #1441486: The literal representation of -(sys.maxint - 1)
617 again evaluates to a int object, not a long.
618
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000619- Bug #1501934: The scope of global variables that are locally assigned
620 using augmented assignment is now correctly determined.
621
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000622- Bug #927248: Recursive method-wrapper objects can now safely
623 be released.
624
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000625- Bug #1417699: Reject locale-specific decimal point in float()
626 and atof().
627
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000628- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
629 omit a default "error" argument for NULL pointer. This allows
630 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000631
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000632- Bug #1519018: 'as' is now validated properly in import statements.
633
Neal Norwitz28746ab2006-07-09 22:14:42 +0000634- On 64 bit systems, int literals that use less than 64 bits are
635 now ints rather than longs.
636
Neal Norwitzed657552006-07-10 00:04:44 +0000637- Bug #1512814, Fix incorrect lineno's when code at module scope
638 started after line 256.
639
Tim Peters32a83612006-07-10 21:08:24 +0000640- New function ``sys._current_frames()`` returns a dict mapping thread
641 id to topmost thread stack frame. This is for expert use, and is
642 especially useful for debugging application deadlocks. The functionality
643 was previously available in Fazal Majid's ``threadframe`` extension
644 module, but it wasn't possible to do this in a wholly threadsafe way from
645 an extension.

662
Thomas Woutersadd19112006-07-05 11:03:49 +0000663- string.Template() now correctly handles tuple-values. Previously,
664 multi-value tuples would raise an exception and single-value tuples would
665 be treated as the value they contain, instead.
666
Martin v. Löwisede77f52006-07-03 13:01:35 +0000667- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

683 socket again, which then gets closed as it becomes unreferenced.
684
Fred Drake10497c82006-06-29 02:57:48 +0000685- Bug #1504333: Make sgmllib support angle brackets in quoted
686 attribute values.
687
688- Bug #853506: Fix IPv6 address parsing in unquoted attributes in

690
Georg Brandl1be63af2006-06-28 20:23:25 +0000691- Fix a bug in the turtle module's end_fill function.
692
Brett Cannon53ab5b72006-06-22 16:49:14 +0000693- Bug #1510580: The 'warnings' module improperly required that a Warning
694 category be either a types.ClassType and a subclass of Warning. The proper
695 check is just that it is a subclass with Warning as the documentation states.
696
Georg Brandlad29e632006-06-21 17:45:17 +0000697- The compiler module now correctly compiles the new try-except-finally
698 statement (bug #1509132).
699
Neal Norwitz60373cd2006-06-22 06:30:50 +0000700- The wsgiref package is now installed properly on Unix.
701
Vinay Sajip28e57612006-07-01 10:45:20 +0000702- A bug was fixed in logging.config.fileConfig() which caused a crash on
703 shutdown when fileConfig() was called multiple times.
704
Gerhard Häring762fbd32006-07-02 17:48:30 +0000705- The sqlite3 module did cut off data from the SQLite database at the first
706 null character before sending it to a custom converter. This has been fixed
707 now.

710-----------------
711
Tim Peters112aad32006-07-19 00:03:19 +0000712- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
713 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
714 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000715
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000716- Assigning None to pointer type fields in ctypes structures possible
717 overwrote the wrong fields, this is fixed now.
718
719- Fixed a segfault in _ctypes when ctypes.wintypes were imported
720 on non-Windows platforms.
721
722- Bug #1518190: The ctypes.c_void_p constructor now accepts any
723 integer or long, without range checking.
724
725- Patch #1517790: It is now possible to use custom objects in the ctypes
726 foreign function argtypes sequence as long as they provide a from_param
727 method, no longer is it required that the object is a ctypes type.
728
729- The '_ctypes' extension module now works when Python is configured
730 with the --without-threads option.
731
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000732- Bug #1513646: os.access on Windows now correctly determines write

745
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000746- Automate Windows build process for the Win64 SSL module.
747
Tim Peters32a83612006-07-10 21:08:24 +0000748- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000749 Previously, the slight difference could cause compilation errors of the
750 'zlib' module on systems with more than one version of zlib.
751
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000752- The MSI compileall step was fixed to also support a TARGETDIR
753 with spaces in it.
754

783Core and builtins
784-----------------
785
Georg Brandla56b9152006-06-19 06:35:54 +0000786- Patch #1507676: Error messages returned by invalid abstract object operations
787 (such as iterating over an integer) have been improved and now include the
788 type of the offending object to help with debugging.
789
Brett Cannonea3912b2006-06-13 21:46:41 +0000790- Bug #992017: A classic class that defined a __coerce__() method that returned
791 its arguments swapped would infinitely recurse and segfault the interpreter.
792
Neal Norwitz909eb122006-06-12 02:13:21 +0000793- Fix the socket tests so they can be run concurrently.
794
Neal Norwitzb9845e72006-06-12 02:11:18 +0000795- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000796 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000797
Brett Cannon22565aa2006-06-09 22:31:23 +0000798- Bug #532646: object.__call__() will continue looking for the __call__
799 attribute on objects until one without one is found. This leads to recursion
800 when you take a class and set its __call__ attribute to an instance of the
801 class. Originally fixed for classic classes, but this fix is for new-style.
802 Removes the infinite_rec_3 crasher.
803
Georg Brandl24250812006-06-09 18:45:48 +0000804- The string and unicode methods startswith() and endswith() now accept
805 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
806
Brett Cannonde3b0522006-06-08 17:00:45 +0000807- Buffer objects, at the C level, never used the char buffer
808 implementation even when the char buffer for the wrapped object was
809 explicitly requested (originally returned the read or write buffer).
810 Now a TypeError is raised if the char buffer is not present but is
811 requested.
812
Georg Brandlddbaa662006-06-04 21:56:52 +0000813- Patch #1346214: Statements like "if 0: suite" are now again optimized
814 away like they were in Python 2.4.
815
Georg Brandlb7c8f542006-05-27 12:30:25 +0000816- Builtin exceptions are now full-blown new-style classes instead of
817 instances pretending to be classes, which speeds up exception handling
818 by about 80% in comparison to 2.5a2.
819
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000820- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
821 Unicode 4.1.
822
Georg Brandlf4ef1162006-05-26 18:03:31 +0000823- Patch #921466: sys.path_importer_cache is now used to cache valid and
824 invalid file paths for the built-in import machinery which leads to
825 fewer open calls on startup.
826
Tim Peters696cf432006-05-24 21:10:40 +0000827- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
828 of-2 bases. The largest speedup is for inputs with about 1000 decimal
829 digits. Conversion from non-power-of-2 bases remains quadratic-time in
830 the number of input digits (it was and remains linear-time for bases
831 2, 4, 8, 16 and 32).
832
Tim Petersb713ec22006-05-23 18:45:30 +0000833- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
834 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
835 an integer close to ``sys.maxint``. This was repaired by patch
836 #1335972, which also gives a nice speedup.
837
Richard Jonescebbefc2006-05-23 18:28:17 +0000838- Patch #1337051: reduced size of frame objects.
839
840- PyErr_NewException now accepts a tuple of base classes as its
841 "base" parameter.
842
Richard Jones7c88dcc2006-05-23 10:37:38 +0000843- Patch #876206: function call speedup by retaining allocated frame
844 objects.
845
Georg Brandl7b90e162006-05-18 07:01:27 +0000846- Bug #1462152: file() now checks more thoroughly for invalid mode
847 strings and removes a possible "U" before passing the mode to the
848 C library function.
849
Neal Norwitz1004a532006-05-15 07:17:23 +0000850- Patch #1488312, Fix memory alignment problem on SPARC in unicode
851
Neal Norwitz373f0a72006-05-15 07:04:36 +0000852- Bug #1487966: Fix SystemError with conditional expression in assignment
853
Martin v. Löwis879768d2006-05-11 13:28:43 +0000854- WindowsError now has two error code attributes: errno, which carries
855 the error values from errno.h, and winerror, which carries the error
856 values from winerror.h. Previous versions put the winerror.h values
857 (from GetLastError()) into the errno attribute.
858
Martin v. Löwis77736712006-05-04 05:51:03 +0000859- Patch #1475845: Raise IndentationError for unexpected indent.
860
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000861- Patch #1479181: split open() and file() from being aliases for each other.
862
Tim Peters44bd9862006-06-01 13:49:23 +0000863- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
864 methods were always silently ignored by dictionaries when comparing keys.
865 They are now passed through (except when using the C API function
866 ``PyDict_GetItem()``, whose semantics did not change).
867
868- Bug #1456209: In some obscure cases it was possible for a class with a
869 custom ``__eq__()`` method to confuse dict internals when class instances
870 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
871 No, you don't have any code that did this ;-)

879
Brett Cannon6ee7d012006-06-08 16:23:04 +0000880- Change binascii.hexlify to accept a read-only buffer instead of only a char
881 buffer and actually follow its documentation.
882
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000883- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
884
Nick Coghlanc649ec52006-05-29 12:43:05 +0000885- Patch #1478788 (modified version): The functional extension module has
886 been renamed to _functools and a functools Python wrapper module added.
887 This provides a home for additional function related utilities that are
888 not specifically about functional programming. See PEP 309.
889
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000890- Patch #1493701: performance enhancements for struct module.

898 enabled builds on Windows and systems with Posix threads support.
899
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000900- On Win32, os.listdir now supports arbitrarily-long Unicode path names
901 (up to the system limit of 32K characters).
902
903- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
904 As a result, these functions now raise WindowsError instead of OSError.
905
Tim Peters7a822da2006-05-25 21:50:17 +0000906- ``time.clock()`` on Win64 should use the high-performance Windows
907 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
908 Windows platforms).
909
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000910- Calling Tk_Init twice is refused if the first call failed as that
911 may deadlock.
912
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000913- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
914 accept it without potentially using an uninitialized pointer.
915
916- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
917 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smith372b5832006-06-05 18:48:21 +0000923- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
924 parameter is supplied. [SF pybsddb bug #1477863]
925
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000926- bsddb: the __len__ method of a DB object has been fixed to return correct
927 results. It could previously incorrectly return 0 in some cases.
928 Fixes SF bug 1493322 (pybsddb bug 1184012).
929
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000930- bsddb: the bsddb.dbtables Modify method now raises the proper error and
931 aborts the db transaction safely when a modifier callback fails.
932 Fixes SF python patch/bug #1408584.
933
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000934- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000935 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000936 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
937 database calls that would previously deadlock. [SF python bug #775414]
938
Vinay Sajip28e57612006-07-01 10:45:20 +0000939- Patch #1446489: add support for the ZIP64 extensions to zipfile.

961 mime.types file for determining MIME types.
962
Georg Brandl2605ca82006-06-14 06:08:31 +0000963- Bug #1339007: Shelf objects now don't raise an exception in their
964 __del__ method when initialization failed.
965
Martin v. Löwisd8251432006-06-14 05:21:04 +0000966- Patch #1455898: The MBCS codec now supports the incremental mode for
967 double-byte encodings.
968
Tim Peters43898b42006-06-14 04:09:25 +0000969- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
970 guarantee that adjacent triples in the return list always describe
971 non-adjacent blocks. Previously, a pair of matching blocks could end
972 up being described by multiple adjacent triples that formed a partition
973 of the matching pair.
974
Greg Ward0e0c9f42006-06-11 16:24:11 +0000975- Bug #1498146: fix optparse to handle Unicode strings in option help,
976 description, and epilog.
977
Greg Wardd1c797e2006-06-11 14:42:41 +0000978- Bug #1366250: minor optparse documentation error.
979
Greg Ward7f547402006-06-11 00:40:49 +0000980- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
981 clarify docs.
982
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000983- The wsgiref package has been added to the standard library.
984
Nick Coghlan676725d2006-06-08 13:54:49 +0000985- The functions update_wrapper() and wraps() have been added to the functools
986 module. These make it easier to copy relevant metadata from the original
987 function when writing wrapper functions.
988
Tim Petersd6a9eef2006-06-05 01:48:21 +0000989- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
990 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000991
Martin v. Löwis3f767792006-06-04 19:36:28 +0000992- Patch #1359618: Speed up charmap encoder by using a trie structure
993 for lookup.
994
Tim Petersd609b1a2006-06-02 23:22:51 +0000995- The functions in the ``pprint`` module now sort dictionaries by key
996 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
997 if and only if its display required more than one line, although that
998 wasn't documented. The new behavior increases predictability; e.g.,
999 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1000
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001001- Patch #1497027: try HTTP digest auth before basic auth in urllib2

1005 default HTTP and HTTPS ports.
1006

1010
Georg Brandlb89316f2006-05-17 15:51:16 +00001011- Patch #1180296: Two new functions were added to the locale module:
1012 format_string() to get the effect of "format % items" but locale-aware,
1013 and currency() to format a monetary number with currency sign.
1014
Georg Brandle3a25832006-05-17 14:56:04 +00001015- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1016 and several features added, such as speed and geometry control.
1017
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001018- Patch #1488881: add support for external file objects in bz2 compressed
1019 tarfiles.
1020
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001021- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1022 stdout arguments, making it possible to redirect input and output
1023 for remote debugging.
1024
1025- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1026 a couple of issues, notably handling of long file names using the
1027 GNU LONGNAME extension.
1028
1029- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1030 new flag when ``name`` is already the name of an option flag.
1031
1032- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1033 package.
1034
1035- Patch #1472854: make the rlcompleter.Completer class usable on non-
1036 UNIX platforms.
1037
1038- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

1076Core and builtins
1077-----------------
1078
Thomas Heller1b046642006-04-18 18:51:06 +00001079- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1080 by converting these apis from macros into exported functions again:
1081
1082 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1083 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1084 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1085 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1086 PyRun_String Py_CompileString
1087
Martin v. Löwis45294a92006-04-18 06:24:08 +00001088- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1089
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001090- All uses of PyStructSequence_InitType have been changed to initialize
1091 the type objects only once, even if the interpreter is initialized
1092 multiple times.
1093
Neal Norwitz61546162006-04-14 05:20:28 +00001094- Bug #1454485, array.array('u') could crash the interpreter. This was
1095 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1096 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1097
1098- Py_UNICODE is unsigned. It was always documented as unsigned, but
1099 due to a bug had a signed value in previous versions.
1100
Tim Peters3a5e8b12006-04-11 01:44:07 +00001101- Patch #837242: ``id()`` of any Python object always gives a positive
1102 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1103 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001104 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001105 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001106
Tim Peters3a5e8b12006-04-11 01:44:07 +00001107 def __hash__(self):
1108 return id(self) # WRONG
1109
1110 because a hash result must be a (short) Python int but it was always
1111 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001112 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001113 was always usable as a hash value before this patch. That's no longer
1114 necessarily so.
1115
1116- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001117 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001118 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001119 #1454844)
1120
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001121- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1122 involving generators that have paused outside of any ``try`` or ``with``
1123 blocks. (In 2.5a1, a paused generator that was part of a reference
1124 cycle could not be garbage collected, regardless of whether it was
1125 paused in a ``try`` or ``with`` block.)

Tim Peters711bf302006-04-25 03:31:36 +00001157- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1158 a doctest to be skipped (the code is not run, and the expected output
1159 or exception is ignored).
1160
Nick Coghlanda2268f2006-04-24 04:37:15 +00001161- Fixed contextlib.nested to cope with exceptions being raised and
1162 caught inside exit handlers.
1163
Greg Wardab05edc2006-04-23 03:47:58 +00001164- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1165 hex, octal, or binary; add ``append_const`` action; keep going if
1166 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1167 added ``epilog`` for better help generation).
1168
Tim Peters21fbd572006-04-21 21:18:10 +00001169- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1170 called from a thread spawned as a side effect of importing a module.
1171
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001172- The pydoc module now supports documenting packages contained in
1173 .zip or .egg files.
1174
1175- The pkgutil module now has several new utility functions, such
1176 as ``walk_packages()`` to support working with packages that are either
1177 in the filesystem or zip files.
1178
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001179- The mailbox module can now modify and delete messages from
1180 mailboxes, in addition to simply reading them. Thanks to Gregory
1181 K. Johnson for writing the code, and to the 2005 Google Summer of
1182 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001183
Tim Petersc7605f22006-04-17 21:12:33 +00001184- The ``__del__`` method of class ``local`` in module ``_threading_local``
1185 returned before accomplishing any of its intended cleanup.
1186
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001187- Patch #790710: Add breakpoint command lists in pdb.

Hye-Shik Changf4795c82006-04-26 19:20:26 +00001227- Fixed a libffi build problem on MIPS systems.
1228
Tim Peters8931ff12006-05-13 23:28:20 +00001229- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1230 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1231 and "%zu" for unsigned integers of type ``size_t``.
1232
Anthony Baxter51bcb682006-04-05 14:51:42 +00001233Tests
1234-----
1235
Nick Coghlanda2268f2006-04-24 04:37:15 +00001236- test_contextlib now checks contextlib.nested can cope with exceptions
1237 being raised and caught inside exit handlers.
1238
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001239- test_cmd_line now checks operation of the -m and -c command switches
1240
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001241- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1242 it separately and by hand. It also wasn't cleaning up its changes to
1243 the current Decimal context.
1244
Thomas Woutersabd08882006-04-26 15:53:30 +00001245- regrtest.py now has a -M option to run tests that test the new limits of
1246 containers, on 64-bit architectures. Running these tests is only sensible
1247 on 64-bit machines with more than two gigabytes of memory. The argument
1248 passed is the maximum amount of memory for the tests to use.
1249
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001250Tools
1251-----
1252
1253- Added the Python benchmark suite pybench to the Tools/ directory;
1254 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001256Documentation
1257-------------
1258
Tim Petersb06d28c2006-05-12 01:57:59 +00001259- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1260
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001261- PEP 343: Added Context Types section to the library reference
1262 and attempted to bring other PEP 343 related documentation into
1263 line with the implementation and/or python-dev discussions.
1264
Tim Peters8dc73d22006-04-24 02:03:16 +00001265- Bug #1337990: clarified that ``doctest`` does not support examples
1266 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +00001267

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001269What's New in Python 2.5 alpha 1?
1270=================================
1271
Anthony Baxterebed3f62006-04-03 15:03:44 +00001272*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001273
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001274Core and builtins
1275-----------------
1276
Nick Coghlan43832302006-04-23 17:04:07 +00001277- PEP 338: -m command line switch now delegates to runpy.run_module
1278 allowing it to support modules in packages and zipfiles
1279
Martin v. Löwisc661b882006-04-20 04:54:23 +00001280- On Windows, .DLL is not an accepted file name extension for
1281 extension modules anymore; extensions are only found if they
1282 end in .PYD.
1283
Martin v. Löwisea62d252006-04-03 10:56:49 +00001284- Bug #1421664: sys.stderr.encoding is now set to the same value as
1285 sys.stdout.encoding.
1286
Neal Norwitz92e212f2006-04-03 04:48:37 +00001287- __import__ accepts keyword arguments.
1288
Georg Brandlccadf842006-03-31 18:54:53 +00001289- Patch #1460496: round() now accepts keyword arguments.
1290
Anthony Baxter262c00a2006-03-30 10:53:17 +00001291- Fixed bug #1459029 - unicode reprs were double-escaped.
1292
Hye-Shik Changd478f342006-03-23 12:32:36 +00001293- Patch #1396919: The system scope threads are reenabled on FreeBSD
1294 5.4 and later versions.
1295
Neal Norwitze98ccf62006-03-23 05:39:47 +00001296- Bug #1115379: Compiling a Unicode string with an encoding declaration
1297 now gives a SyntaxError.
1298
Georg Brandlabd1ff82006-03-18 07:59:59 +00001299- Previously, Python code had no easy way to access the contents of a
1300 cell object. Now, a ``cell_contents`` attribute has been added
1301 (closes patch #1170323).
1302
Tim Peterscf79aac2006-03-16 01:14:46 +00001303- Patch #1123430: Python's small-object allocator now returns an arena to
1304 the system ``free()`` when all memory within an arena becomes unused
1305 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1306 freed. Some applications will see a drop in virtual memory size now,
1307 especially long-running applications that, from time to time, temporarily
1308 use a large number of small objects. Note that when Python returns an
1309 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001310 platform C library will in turn return that memory to the operating system.
1311 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001312 appears to be effective at least on Microsoft C and gcc-based systems.
1313 Thanks to Evan Jones for hard work and patience.
1314
Georg Brandl533ff6f2006-03-08 18:09:27 +00001315- Patch #1434038: property() now uses the getter's docstring if there is
1316 no "doc" argument given. This makes it possible to legitimately use
1317 property() as a decorator to produce a read-only property.
1318
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001319- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1320 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1321 of requiring an int or long in slicing and a few other contexts, enabling
1322 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1323
Neal Norwitz995acdf2006-03-07 05:01:00 +00001324- Fixed various bugs reported by Coverity's Prevent tool.
1325
Brett Cannonbf364092006-03-01 04:25:17 +00001326- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1327 new exception base class, BaseException, which has a new message attribute.
1328 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1329 Raising a string exception now raises a DeprecationWarning.
1330
Thomas Woutersfb609f42006-02-28 16:37:25 +00001331- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1332 explicitly relative, using 'from .module import name' to mean 'from the same
1333 package as this module is in. Imports without dots still default to the
1334 old relative-then-absolute, unless 'from __future__ import
1335 absolute_import' is used.
1336
Brett Cannona7446e32006-02-27 23:39:10 +00001337- Properly check if 'warnings' raises an exception (usually when a filter set
1338 to "error" is triggered) when raising a warning for raising string
1339 exceptions.
1340
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001341- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001342 The name was removed from Include/code.h.
1343
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001344- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001345
Guido van Rossum1968ad32006-02-25 22:38:04 +00001346- Patch 1433928:
1347 - The copy module now "copies" function objects (as atomic objects).
1348 - dict.__getitem__ now looks for a __missing__ hook before raising
1349 KeyError.
1350
Tim Peters84ef21c2006-02-28 20:39:06 +00001351- PEP 343: with statement implemented. Needs ``from __future__ import
1352 with_statement``. Use of 'with' as a variable will generate a warning.
1353 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001354 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001355 The following objects have __context__ methods:
1356 - The built-in file type.
1357 - The thread.LockType type.
1358 - The following types defined by the threading module:
1359 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1360 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001361
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001362- Fix the encodings package codec search function to only search
1363 inside its own package. Fixes problem reported in patch #1433198.
1364
1365 Note: Codec packages should implement and register their own
1366 codec search function. PEP 100 has the details.
1367
Tim Peters9ea89d22006-06-04 03:26:02 +00001368- PEP 353: Using ``Py_ssize_t`` as the index type.
1369
1370- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1371 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1372 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1373 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1374 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001375
Neal Norwitzfc76d632006-01-10 06:03:13 +00001376- Patch #1400181, fix unicode string formatting to not use the locale.
1377 This is how string objects work. u'%f' could use , instead of .
1378 for the decimal point. Now both strings and unicode always use periods.
1379
Neal Norwitz671b9e32006-01-09 07:07:12 +00001380- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1381 configure would break checking curses.h.
1382
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001383- Bug #959576: The pwd module is now builtin. This allows Python to be
1384 built on UNIX platforms without $HOME set.
1385
Neal Norwitzc10978f2005-12-19 06:07:16 +00001386- Bug #1072182, fix some potential problems if characters are signed.
1387
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001388- Bug #889500, fix line number on SyntaxWarning for global declarations.
1389
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001390- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1391
Neal Norwitze7214a12005-12-18 05:03:17 +00001392- Support for converting hex strings to floats no longer works.
1393 This was not portable. float('0x3') now raises a ValueError.
1394
Barry Warsaw2a38a862005-12-18 01:27:35 +00001395- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001396 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001397 is now displayed in interactive prompt banner.
1398
Georg Brandlfa166682005-12-17 21:45:17 +00001399- Implementation of PEP 341 - Unification of try/except and try/finally.
1400 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001401 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001402
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001403- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1404 now encodes backslash correctly.
1405
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001406- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1407
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001408- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001409 and long longs.
1410
Neal Norwitz67715f02005-11-09 06:59:35 +00001411- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001412 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001413 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001414
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001415- Replaced most Unicode charmap codecs with new ones using the
1416 new Unicode translate string feature in the builtin charmap
1417 codec; the codecs were created from the mapping tables available
1418 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1419 encodings now include a mapping for the Apple logo)
1420
Tim Peterse3547fd2005-12-16 23:13:57 +00001421- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001422
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001423- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001424
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001425- A new AST parser implementation was completed. The abstract
1426 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001427 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001428
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001429- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001430 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1431
Neal Norwitz708e51a2005-10-03 04:48:15 +00001432- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1433
Neal Norwitz11bd1192005-10-03 00:54:56 +00001434- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1435 Provide a warning when a directory is passed on the command line.
1436
Neal Norwitz40d37812005-10-02 01:48:49 +00001437- Fix segfault with invalid coding.
1438
1439- SF bug #772896: unknown encoding results in MemoryError.
1440
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001441- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001442 supported a __len__() method which evaluated to False when the iterator
1443 was empty.
1444
Guido van Rossum630db602005-09-20 18:49:54 +00001445- On 64-bit platforms, when __len__() returns a value that cannot be
1446 represented as a C int, raise OverflowError.
1447
Skip Montanarof8948ca2005-09-19 03:54:46 +00001448- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001449 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001450
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001451- SF bug #893549: parsing keyword arguments was broken with a few format
1452 codes.
1453
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001454- Changes donated by Elemental Security to make it work on AIX 5.3
1455 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1456 bug #105470: test_pwd fails on 64bit system (Opteron).
1457
Guido van Rossum539c6622005-09-14 17:49:54 +00001458- Changes donated by Elemental Security to make it work on HP-UX 11 on
1459 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1460
Georg Brandl4550b8d2005-08-26 06:43:52 +00001461- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001462 (fixes bug #1119418).
1463
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001464- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1465
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001466- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1467 exceptions that cause a function to exit.
1468
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001469- The implementation of set() and frozenset() was revised to use its
1470 own internal data structure. Memory consumption is reduced by 1/3
1471 and there are modest speed-ups as well. The API is unchanged.
1472
Tim Petersde7990b2005-07-17 23:45:23 +00001473- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1474
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001475- SF bug #1229429: PyObject_CallMethod failed to decrement some
1476 reference counts in some error exit cases.
1477
Tim Petersecc6e6a2005-07-10 22:30:55 +00001478- SF bug #1185883: Python's small-object memory allocator took over
1479 a block managed by the platform C library whenever a realloc specified
1480 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001481 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001482 portable way to copy data from the C-managed block into Python's
1483 small-object space without risking a memory fault. Python's small-object
1484 realloc now leaves such blocks under the control of the platform C
1485 realloc.
1486
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001487- SF bug #1232517: An overflow error was not detected properly when
1488 attempting to convert a large float to an int in os.utime().
1489
Raymond Hettinger3296e692005-06-29 23:29:56 +00001490- SF bug #1224347: hex longs now print with lowercase letters just
1491 like their int counterparts.
1492
Michael W. Hudson188d4362005-06-20 16:52:57 +00001493- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1494 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1495 interpreter states; back out that fix and do a better job (see

1497 for a longer write-up of the problem).
1498
Michael W. Hudsondf888462005-06-03 14:41:55 +00001499- SF patch #1180995: marshal now uses a binary format by default when
1500 serializing floats.
1501
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001502- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1503 the routines that promise to produce IEEE 754 binary representations
1504 of floats now simply copy bytes around.
1505
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001506- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1507 278.
1508
Brett Cannonc3647ac2005-04-26 03:45:26 +00001509- patch #1109424: int, long, float, complex, and unicode now check for the
1510 proper magic slot for type conversions when subclassed. Previously the
1511 magic slot was ignored during conversion. Semantics now match the way
1512 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001513 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001514 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001515 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001516
Barry Warsawc8d907c2005-04-19 23:43:40 +00001517- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1518 NULL, now raise an AttributeError when attempting to set or delete the
1519 attribute. Previously a TypeError was raised, but this was inconsistent
1520 with the equivalent pure-Python implementation.
1521
Michael W. Hudson774479c2005-04-18 08:46:17 +00001522- It is now safe to call PyGILState_Release() before
1523 PyEval_InitThreads() (note that if there is reason to believe there
1524 are multiple threads around you still must call PyEval_InitThreads()
1525 before using the Python API; this fix is for extension modules that
1526 have no way of knowing if Python is multi-threaded yet).
1527
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001528- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1529 disabled caused a crash.
1530
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001531- Bug #1165306: instancemethod_new allowed the creation of a method
1532 with im_class == im_self == NULL, which caused a crash when called.
1533
Tim Petersecc6e6a2005-07-10 22:30:55 +00001534- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001535 fixes the crash seen in bug #1165761
1536
Raymond Hettinger96229b12005-03-11 06:49:40 +00001537- Added two new builtins, any() and all().
1538
Brett Cannon409d8f22005-03-05 06:47:57 +00001539- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001540 (e.g., ``class C(): pass`` is no longer a syntax error).
1541 Patch #1176012 added support to the 'parser' module and 'compiler' package
1542 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001543
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001544- Patch #1115086: Support PY_LONGLONG in structmember.
1545
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001546- Bug #1155938: new style classes did not check that __init__() was
1547 returning None.
1548
Tim Petersecc6e6a2005-07-10 22:30:55 +00001549- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001550 ('\') with a specific error message.
1551
Martin v. Löwisff232d72005-03-03 09:24:38 +00001552- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1553
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001554- Bug #1124295: the __name__ attribute of file objects was
1555 inadvertently made inaccessible in restricted mode.
1556
Tim Petersecc6e6a2005-07-10 22:30:55 +00001557- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001558 an ferror() call.
1559
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001560- min() and max() now support key= arguments with the same meaning as in
1561 list.sort().
1562
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001563- The peephole optimizer now performs simple constant folding in expressions:
1564 (2+3) --> (5).
1565
Raymond Hettingera422c342005-01-11 03:03:27 +00001566- set and frozenset objects can now be marshalled. SF #1098985.
1567
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001568- Bug #1077106: Poor argument checking could cause memory corruption
1569 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001570
Jeremy Hyltonab630502005-02-04 18:44:06 +00001571- The parser did not complain about future statements in illegal
1572 positions. It once again reports a syntax error if a future
1573 statement occurs after anything other than a doc string.
1574
Neil Schemenauercf52c072005-08-12 17:34:58 +00001575- Change the %s format specifier for str objects so that it returns a
1576 unicode instance if the argument is not an instance of basestring and
1577 calling __str__ on the argument returns a unicode instance.
1578
Tim Petersf4e69282006-02-27 17:15:31 +00001579- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1580 current thread state when the auto-GIL-state machinery knows about
1581 it (since the thread state is being deleted, continuing to remember it
1582 can't help, but can hurt if another thread happens to get created with
1583 the same thread id).
1584

1613 for applications that require this specific version (such as IDNA).
1614
Neal Norwitzb62c4332006-03-04 18:35:47 +00001615- The timing module is no longer built by default. It was deprecated

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001775- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1776 been renamed to have only a single underscore prefix. This was done to
1777 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001778
Nick Coghlan43832302006-04-23 17:04:07 +00001779- PEP 338: new module runpy defines a run_module function to support
1780 executing modules which provide access to source code or a code object
1781 via the PEP 302 import mechanisms.
1782
Anthony Baxter93f5b932006-04-03 08:05:07 +00001783- The email module's parsedate_tz function now sets the daylight savings

1791 in attribute values.
1792
Anthony Baxterc51ee692006-04-01 00:57:31 +00001793- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001794 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001795 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001796 module will not be built.
1797
Tim Petersc17976e2006-04-01 00:26:53 +00001798- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1799 aren't officially supported here, and trying to use them will probably
1800 raise an exception some day. But dicts have been allowed, and "mostly
1801 worked", so support for them won't go away without warning.
1802
Georg Brandl338ef7d2006-03-31 18:42:16 +00001803- Bug #1445068: getpass.getpass() can now be given an explicit stream

1821
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001822- email 4.0 package now integrated. This is largely the same as the email 3.0
1823 package that was included in Python 2.3, except that PEP 8 module names are
1824 now used (e.g. mail.message instead of email.Message). The MIME classes
1825 have been moved to a subpackage (e.g. email.mime.text instead of
1826 email.MIMEText). The old names are still supported for now. Several
1827 deprecated Message methods have been removed and lots of bugs have been
1828 fixed. More details can be found in the email package documentation.
1829
Walter Dörwald40108c92006-03-27 08:15:44 +00001830- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1831 (a subclass of tuple) that provides incremental decoders and encoders
1832 (a way to use stateful codecs without the stream API). Python functions
1833 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1834 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1835 have been added.

1838 a ValueError instead of a StopIteration now (like file and cString.String do).
1839 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1840 called before (like file and StringIO.StringIO do).

1915 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1916 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1917 Ronald L. Rivest offered this advice for Python:
1918
1919 "The consensus of researchers in this area (at least as
1920 expressed at the NIST Hash Function Workshop 10/31/05),
1921 is that SHA-256 is a good choice for the time being, but
1922 that research should continue, and other alternatives may
1923 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001924
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001925- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl9166e1a2005-06-04 09:20:03 +00002025- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2026
Georg Brandl268e61c2005-06-03 14:28:50 +00002027- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2028 component of the path.
2029
Skip Montanaro174dd222005-05-14 20:54:16 +00002030- Patch #1120353: The xmlrpclib module provides better, more transparent,
2031 support for datetime.{datetime,date,time} objects. With use_datetime set
2032 to True, applications shouldn't have to fiddle with the DateTime wrapper
2033 class at all.
2034
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002035- distutils.commands.upload was added to support uploading distribution
2036 files to PyPI.
2037
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002038- distutils.commands.register now encodes the data as UTF-8 before posting
2039 them to PyPI.
2040
Raymond Hettinger267b8682005-03-27 10:47:39 +00002041- decimal operator and comparison methods now return NotImplemented
2042 instead of raising a TypeError when interacting with other types. This
2043 allows other classes to implement __radd__ style methods and have them
2044 work as expected.
2045
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002046- Bug #1163325: Decimal infinities failed to hash. Attempting to
2047 hash a NaN raised an InvalidOperation instead of a TypeError.
2048
Tim Petersecc6e6a2005-07-10 22:30:55 +00002049- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002050 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2051
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002052- Patch #1043890: Add extractall method to tarfile.

Martin v. Löwisc72dd382005-03-04 13:50:17 +00002054- Patch #1075887: Don't require MSVC in distutils if there is nothing
2055 to build.
2056
Martin v. Löwis637431b2005-03-03 23:12:42 +00002057- Patch #1103407: Properly deal with tarfile iterators when untarring
2058 symbolic links on Windows.
2059

Martin v. Löwisa4dac402005-03-03 11:39:45 +00002061 profile.py if available.
2062
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002063- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2064
Martin v. Löwisc5574e82005-03-03 10:57:37 +00002065- Patch #1117454: Remove code to special-case cookies without values
2066 in LWPCookieJar.
2067
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00002068- Patch #1117339: Add cookielib special name tests.
2069

2071
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00002072- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
2073
Martin v. Löwisdf241532005-03-03 08:17:42 +00002074- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
2075
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002076- Patch #1104111: Alter setup.py --help and --help-commands.
2077
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002078- Patch #1121234: Properly cleanup _exit and tkerror commands.
2079
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002080- Patch #1049151: xdrlib now unpacks booleans as True or False.
2081
Raymond Hettingerbab41432005-02-05 01:31:19 +00002082- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2083
Guido van Rossumd0641422005-02-03 15:01:24 +00002084- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2085 disables recursive traversal through instance attributes, which can
2086 be exploited in various ways.
2087
Tim Peterse3547fd2005-12-16 23:13:57 +00002088- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002089 flags on the HTTP listening socket.
2090
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002091- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2092 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2093
Fred Drakefbdeaad2006-07-29 16:56:15 +00002094- Patches #893642, #1039083: add allow_none, encoding arguments to
2095 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002096
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002097- Bug #1110478: Revert os.environ.update to do putenv again.
2098
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002099- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2100
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002101- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2102
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002103- Enhancements to the csv module:
2104
2105 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002106 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002107 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002108 + Dialect parameter parsing has been re-implemented to improve error
2109 reporting.
2110 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2111 dictates.
2112 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002113 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002114 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002115 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2116 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002117 + reader now allows \r characters to be quoted (previously it only allowed
2118 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002119 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002120 + Dialect classes passed to the module are no longer instantiated by
2121 the module before being parsed (the former validation scheme required
2122 this, but the mechanism was unreliable).
2123 + The dialect registry now contains instances of the internal
2124 C-coded dialect type, rather than references to python objects.
2125 + the internal c-coded dialect type is now immutable.
2126 + register_dialect now accepts the same keyword dialect specifications
2127 as the reader and writer, allowing the user to register dialects
2128 without first creating a dialect class.
2129 + a configurable limit to the size of parsed fields has been added -
2130 previously, an unmatched quote character could result in the entire
2131 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002132 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002133 the parser field size limit (returning the former limit). The initial
2134 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002135 + A line_num attribute has been added to the reader object, which tracks
2136 the number of lines read from the source iterator. This is not
2137 the same as the number of records returned, as records can span
2138 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002139 + reader and writer objects were not being registered with the cyclic-GC.
2140 This has been fixed.
2141
Brett Cannone6539c42005-01-08 02:43:53 +00002142- _DummyThread objects in the threading module now delete self.__block that is
2143 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2144 lock primitives tend to be limited in number and thus should not be wasted on
2145 a _DummyThread object. Fixes bug #1089632.
2146
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002147- The imghdr module now detects Exif files.
2148
Raymond Hettinger6065d322004-12-20 23:51:53 +00002149- StringIO.truncate() now correctly adjusts the size attribute.
2150 (Bug #951915).
2151
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002152- locale.py now uses an updated locale alias table (built using
2153 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2154 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002155 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002156
Raymond Hettinger3557f422004-12-07 12:02:02 +00002157- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2158
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002159- the pickle module no longer accepts the deprecated None option in the
2160 args tuple returned by __reduce__().
2161
Brett Cannon84667c02004-12-07 03:25:18 +00002162- optparse now optionally imports gettext. This allows its use in setup.py.
2163
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002164- the pickle module no longer uses the deprecated bin parameter.
2165
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002166- the shelve module no longer uses the deprecated binary parameter.
2167
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002168- the pstats module no longer uses the deprecated ignore() method.
2169
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002170- the filecmp module no longer uses the deprecated use_statcache argument.
2171
Raymond Hettinger664347b2004-12-04 21:21:53 +00002172- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2173 extended or overridden by subclasses. Formerly, the subclassed method would
2174 be ignored by the rest of the module. (Bug #1078905).
2175
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002176- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002177 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002178
Walter Dörwald36733692004-12-22 12:50:50 +00002179- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2180 once when a size argument is given. This prevents a buffer overflow in the
2181 tokenizer with very long source lines.
2182
Barry Warsaw538561e2006-01-01 21:48:54 +00002183- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2184 immediately after creating the object, without any intervening
2185 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002186
Skip Montanaro05885812005-01-16 20:48:27 +00002187- The reconvert.quote function can now emit triple-quoted strings. The
2188 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002189
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002190- ``UserString.MutableString`` now supports negative indices in
2191 ``__setitem__`` and ``__delitem__``
2192
Greg Ward40407942005-03-05 02:53:17 +00002193- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2194 correctly.
2195
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002196- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2197 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2198 character even if the user has passed a size parameter to get a proper
2199 line ending. Remove the special handling of a "\r\n" that has been split
2200 between two lines.
2201
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002202- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2203 about illegal code points. The codec now supports PEP 293 style error
2204 handlers.
2205
Walter Dörwald78a78b02005-09-01 12:04:29 +00002206- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002207 from the input stream, so that the output is a byte string in the correct
2208 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002209
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002210- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2211 considering it exactly like a '*'.
2212
Walter Dörwald007f8df2005-10-09 19:42:27 +00002213- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2214 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002215
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002216- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2217
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002218- Patch #1413711: Certain patterns of differences were making difflib
2219 touch the recursion limit.
2220
Walter Dörwald58917a62006-03-31 15:26:22 +00002221- Bug #947906: An object oriented interface has been added to the calendar
2222 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002223 called as a script (e.g. via ``python -mcalendar``). Localized month and
2224 weekday names can be ouput (even if an exotic encoding is used) using
2225 special classes that use unicode.

2228-----
2229
Neal Norwitz602d3392006-03-31 08:21:40 +00002230- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2231 by using -mieee gcc option.
2232
Martin v. Löwis86d66262006-02-17 08:40:11 +00002233- Patch #1432345: Make python compile on DragonFly.
2234
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002235- Build support for Win64-AMD64 was added.
2236
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002237- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2238
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002239- Patch #881820: look for openpty and forkpty also in libbsd.
2240
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002241- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2242 The zlib module is now builtin on Windows.
2243
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002244- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2245
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002246- Bug #1189330: configure did not correctly determine the necessary
2247 value of LINKCC if python was built with GCC 4.0.
2248
Trent Mick8321b422005-07-26 02:29:21 +00002249- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2250 vulnerability in zlib 1.2.1 and 1.2.2.
2251
Brett Cannon08cd5982005-04-24 22:26:38 +00002252- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2253 flags that change binary compatibility. Changes were also made to
2254 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002255 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002256
Bob Ippolitoed233462005-03-29 13:47:59 +00002257- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2258 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2259 no longer exists). This configure patch makes things right.
2260
Martin v. Löwise2713be2005-03-08 15:03:08 +00002261- Bug #1158607: Build with --disable-unicode again.
2262
Brett Cannon46d96232005-02-16 00:07:19 +00002263- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2264 defined. Discovered as a result of not being able to build on OS X.
2265
Brett Cannon516592f2004-12-07 00:42:59 +00002266- setup.py now uses the directories specified in LDFLAGS using the -L option
2267 and in CPPFLAGS using the -I option for adding library and include
2268 directories, respectively, for compiling extension modules against. This has
2269 led to the core being compiled using the values in CPPFLAGS. It also removes
2270 the need for the special-casing of both DarwinPorts and Fink for darwin since
2271 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2272 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2273 Fink, ``-I/opt/local/include`` for DarwinPorts).
2274
Brett Cannon43802422005-02-10 20:48:03 +00002275- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2276 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2277 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2278 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002280C API
2281-----
2282
Tim Petersc9d78aa2006-03-26 23:27:58 +00002283- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2284 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2285 is obtained via the ``PyObject_`` family, it must be released via the
2286 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2287 always been officially true, but when Python's small-object allocator was
2288 introduced, an attempt was made to cater to a few extension modules
2289 discovered at the time that obtained memory via ``PyObject_New`` but
2290 released it via ``PyMem_DEL``. It's years later, and if such code still
