12Core and builtins
13-----------------
14
Neal Norwitzcbeb6872006-10-14 21:33:38 +000015- Update the peephole optimizer to remove more dead code (jumps after returns)
16 and inline unconditional jumps to returns.
17
Georg Brandl2c1375c2006-10-12 11:27:59 +000018- Bug #1545497: when given an explicit base, int() did ignore NULs
19 embedded in the string to convert.
20
Georg Brandl846f73a2006-10-08 07:11:54 +000021- Bug #1569998: break inside a try statement (outside a loop) is now
22 recognized and rejected.
23
Armin Rigo7ccbca92006-10-04 12:17:45 +000024- list.pop(x) accepts any object x following the __index__ protocol.
25
26- Fix some leftovers from the conversion from int to Py_ssize_t
27 (relevant to strings and sequences of more than 2**31 items).
28
29- A number of places, including integer negation and absolute value,
30 were fixed to not rely on undefined behaviour of the C compiler
31 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +000032
Georg Brandl3267d282006-09-30 09:03:42 +000033- Bug #1566800: make sure that EnvironmentError can be called with any
34 number of arguments, as was the case in Python 2.4.
35
Georg Brandl5d59c092006-09-30 08:43:30 +000036- Patch #1567691: super() and new.instancemethod() now don't accept
37 keyword arguments any more (previously they accepted them, but didn't
38 use them).
39
Georg Brandla10d3af2006-09-24 12:35:36 +000040- Fix a bug in the parser's future statement handling that led to "with"
41 not being recognized as a keyword after, e.g., this statement:
42 from __future__ import division, with_statement
43
Neal Norwitz3a230172006-09-22 08:18:10 +000044- Bug #1557232: fix seg fault with def f((((x)))) and def f(((x),)).

49
Brett Cannon9adeab72006-09-20 18:34:28 +000050- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
51 allows calling unicode() on exceptions classes directly to succeed.
52
Georg Brandlec6c2df2006-09-11 09:38:35 +000053- Make _PyGILState_NoteThreadState() static, it was not used anywhere
54 outside of pystate.c and should not be necessary.
55
Georg Brandl4e933132006-09-06 20:05:58 +000056- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

61 imports (if not in package and if beyond toplevel package).
62
Tim Petersc10c9d02006-09-05 02:18:09 +000063- Overflow checking code in integer division ran afoul of new gcc
64 optimizations. Changed to be more standard-conforming.

67
Neal Norwitza22975f2006-09-05 02:24:03 +000068- Patch #1546288: fix seg fault in dict_equal due to ref counting bug.
69
Neal Norwitzd34e4272006-09-05 02:36:20 +000070- The return tuple from str.rpartition(sep) is (tail, sep, head) where
71 head is the original string if sep was not found.
72
Neal Norwitzdac090d2006-09-05 03:53:08 +000073- Bug #1520864: unpacking singleton tuples in list comprehensions and
74 generator expressions (x for x, in ... ) works again. Fixing this problem
75 required changing the .pyc magic number. This means that .pyc files
76 generated before 2.5c2 will be regenerated.
77
Neal Norwitzca460d92006-09-06 06:28:06 +000078- with and as are now keywords.

110 being raised when print_exc() was called without an exception set.
111 In version 2.4, this printed "None", restored that behavior.
112
Georg Brandl2c94bf72006-09-24 10:36:01 +0000113- Make webbrowser.BackgroundBrowser usable in Windows (it wasn't because

176 been defined. This prevents an interactive Python from waking up 10
177 times per second. Patch by Richard Boulton.

Guido van Rossumc69ac252006-08-10 18:09:25 +0000237What's New in Python 2.5 release candidate 1?
238=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000239
Anthony Baxterb4096662006-08-16 03:42:26 +0000240*Release date: 17-AUG-2006*

242Core and builtins
243-----------------
244
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000245- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000246 compared equal or unequal to a string and a UnicodeDecodeError
247 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000248
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000249 Instead, the equal (==) and unequal (!=) comparison operators will
250 now issue a UnicodeWarning and interpret the two objects as
251 unequal. The UnicodeWarning can be filtered as desired using
252 the warning framework, e.g. silenced completely, turned into an
253 exception, logged, etc.
254
255 Note that compare operators other than equal and unequal will still
256 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000257
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000258- Fix segfault when doing string formatting on subclasses of long.
259
260- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
261 with new-style classes.
262
263- Fix bug related to __len__ functions returning negative values with
264 classic classes.
265
266- Patch #1538606, Fix __index__() clipping. There were some problems
267 discovered with the API and how integers that didn't fit into Py_ssize_t
268 were handled. This patch attempts to provide enough alternatives
269 to effectively use __index__.
270
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000271- Bug #1536021: __hash__ may now return long int; the final hash
272 value is obtained by invoking hash on the long int.
273
Thomas Hellerab1049c2006-08-08 17:37:00 +0000274- Bug #1536786: buffer comparison could emit a RuntimeWarning.

Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000276- Bug #1535165: fixed a segfault in input() and raw_input() when
277 sys.stdin is closed.
278
Thomas Heller74d36f02006-08-04 18:17:40 +0000279- On Windows, the PyErr_Warn function is now exported from
280 the Python dll again.
281
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000282- Bug #1191458: tracing over for loops now produces a line event
283 on each iteration. Fixing this problem required changing the .pyc
284 magic number. This means that .pyc files generated before 2.5c1
285 will be regenerated.
286
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000287- Bug #1333982: string/number constants were inappropriately stored
288 in the byte code and co_consts even if they were not used, ie
289 immediately popped off the stack.
290
Georg Brandle9462c72006-08-04 18:03:37 +0000291- Fixed a reference-counting problem in property().

298 generated for generator expressions.
299
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000300- The distutils version has been changed to 2.5.0. The change to
301 keep it programmatically in sync with the Python version running
302 the code (introduced in 2.5b3) has been reverted. It will continue
303 to be maintained manually as static string literal.
304
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000305- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000306 and this cannot be converted to the required C type, an exception is
307 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000308 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000309
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000310- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000311 an exception.
312
Tim Petersc10c9d02006-09-05 02:18:09 +0000313- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000314 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000315 workarounds for clocks with low resolution, to stop the code yielding
316 duplicate UUIDs.
317
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000318- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
319 before raising SystemExit, allowing IDLE to honor quit() and exit().
320
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000321- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
322
Georg Brandl7a1af772006-08-14 21:55:28 +0000323- Patch #1536071: trace.py should now find the full module name of a
324 file correctly even on Windows.
325
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000326- logging's atexit hook now runs even if the rest of the module has
327 already been cleaned up.
328
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000329- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000330
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000331- Bug #1531405, format_exception no longer raises an exception if
332 str(exception) raised an exception.
333
Neil Schemenauer06ded092006-08-04 16:20:30 +0000334- Fix a bug in the ``compiler`` package that caused invalid code to be
335 generated for nested functions.
336

342
Georg Brandl3335a7a2006-08-14 21:42:55 +0000343- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
344 raises the correct exceptions.
345
Thomas Heller1ce433e2006-08-14 16:20:04 +0000346- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
347 '-no-stack-protector' compiler flag for OpenBSD has been removed.
348
Thomas Heller86720042006-08-14 11:17:48 +0000349- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
350 uses the _as_parameter_ attribute when objects are passed to foreign
351 function calls. The ctypes version number was changed to 1.0.1.
352
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000353- Bug #1530559, struct.pack raises TypeError where it used to convert.
354 Passing float arguments to struct.pack when integers are expected
355 now triggers a DeprecationWarning.
356

Andrew MacIntyre16ee33a2006-08-06 12:37:03 +0000368- test_threading now skips testing alternate thread stack sizes on
369 platforms that don't support changing thread stack size.
370
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000371

379-----
380
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000381- Bug #1535502, build _hashlib on Windows, and use masm assembler
382 code in OpenSSL.
383
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000384- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Fred Drake53912162006-07-29 13:22:49 +0000400What's New in Python 2.5 beta 3?
401================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000402
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000403*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000404
405Core and builtins
406-----------------
407
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000408- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000409 returned a long (see PEP 353).
410
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000411- Bug #1515471: string.replace() accepts character buffers again.
412
Neal Norwitz07aadb12006-07-30 06:55:48 +0000413- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
414 This provides the proper warning for struct.pack().
415 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
416
Neal Norwitz0d62a062006-07-30 06:53:31 +0000417- Patch #1531113: Fix augmented assignment with yield expressions.
418 Also fix a SystemError when trying to assign to yield expressions.
419
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000420- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
421 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
422 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
423 excessive filesystem operations during imports.
424
Tim Petersbc24eee2006-07-27 01:14:53 +0000425- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
426 operations on signed longs that are formally undefined by C.
427 Unfortunately, at least one compiler now cares about that, so complicated
428 the code to make that compiler happy again.
429
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000430- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
431
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000432- Patch #1232023: Stop including current directory in search
433 path on Windows.
434
Neal Norwitze1fdb322006-07-21 05:32:28 +0000435- Fix some potential crashes found with failmalloc.
436
Neal Norwitze7563102006-07-17 01:00:16 +0000437- Fix warnings reported by Klocwork's static analysis tool.
438
Neal Norwitz84be93b2006-07-16 01:50:38 +0000439- Bug #1512814, Fix incorrect lineno's when code within a function
440 had more than 255 blank lines.
441
Georg Brandl9dceedb2006-07-12 15:31:17 +0000442- Patch #1521179: Python now accepts the standard options ``--help`` and
443 ``--version`` as well as ``/?`` on Windows.
444
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000445- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000446 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000447 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000448
Tim Peters112aad32006-07-19 00:03:19 +0000449- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000450 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000451 new ``sys._current_frames()`` returns a dictionary with one entry,
452 mapping the faux "thread id" 0 to the current frame.
453
Ronald Oussoren3075e162006-07-25 20:28:55 +0000454- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000455
Ronald Oussoren3075e162006-07-25 20:28:55 +0000456
Neal Norwitza1f10902006-07-12 07:28:29 +0000457Library
458-------
459
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000460- Correction of patch #1455898: In the mbcs decoder, set final=False
461 for stream decoder, but final=True for the decode function.
462
Georg Brandl07fec3a2006-08-01 18:49:24 +0000463- os.urandom no longer masks unrelated exceptions like SystemExit or
464 KeyboardInterrupt.
465
Tim Peters4643c2f2006-08-10 22:45:34 +0000466- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000467 shutil.copytree on Windows
468
Georg Brandle34ac7c2006-07-30 11:07:23 +0000469- Bug #1002398: The documentation for os.path.sameopenfile now correctly
470 refers to file descriptors, not file objects.
471
Tim Petersc10c9d02006-09-05 02:18:09 +0000472- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000473 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000474 #1513611, and probably others.
475
Georg Brandledd9b0d2006-07-29 09:33:26 +0000476- Bug #1441397: The compiler module now recognizes module and function
477 docstrings correctly as it did in Python 2.4.
478
Tim Peters6f681472006-07-27 23:44:37 +0000479- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
480 lost that tests are sorted by name before being run. This rarely
481 matters for well-written tests, but can create baffling symptoms if
482 side effects from one test to the next affect outcomes. ``DocTestFinder``
483 has been changed to sort the list of tests it returns.
484
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000485- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000486 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000487
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000488- Bug #978833: Really close underlying socket in _socketobject.close.
489
Georg Brandl8c036cc2006-08-20 13:15:39 +0000490- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
491 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000492
Georg Brandlcf0c1722006-07-26 07:23:32 +0000493- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
494 to recursive calls and call it with the failing package name.
495
Martin v. Löwis0b483032006-07-25 09:53:12 +0000496- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
497
Georg Brandlc13c34c2006-07-24 14:09:56 +0000498- Patch #1515343: Fix printing of deprecated string exceptions with a
499 value in the traceback module.
500
Greg Ward48fae7a2006-07-23 16:05:51 +0000501- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
502
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000503- Patch #1524429: Use repr() instead of backticks in Tkinter again.
504
Brett Cannoncaebe222006-07-18 04:41:36 +0000505- Bug #1520914: Change time.strftime() to accept a zero for any position in its
506 argument tuple. For arguments where zero is illegal, the value is forced to
507 the minimum value that is correct. This is to support an undocumented but
508 common way people used to fill in inconsequential information in the time
509 tuple pre-2.4.
510
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000511- Patch #1220874: Update the binhex module for Mach-O.
512
Barry Warsawb110bad2006-07-21 14:51:07 +0000513- The email package has improved RFC 2231 support, specifically for
514 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
515 (name*0=<blah>) parameter continuations. This may change the types of
516 values returned from email.message.Message.get_param() and friends.
517 Specifically in some cases where non-encoded continuations were used,
518 get_param() used to return a 3-tuple of (None, None, string) whereas now it
519 will just return the string (since non-encoded continuations don't have
520 charset and language parts).
521
522 Also, whereas % values were decoded in all parameter continuations, they are
523 now only decoded in encoded parameter parts.
524
Ronald Oussoren3075e162006-07-25 20:28:55 +0000525- Bug #1517990: IDLE keybindings on MacOS X now work correctly
526
527- Bug #1517996: IDLE now longer shows the default Tk menu when a
528 path browser, class browser or debugger is the frontmost window on MacOS X
529
Barry Warsaw00decd72006-07-27 23:43:15 +0000530- Patch #1520294: Support for getset and member descriptors in types.py,
531 inspect.py, and pydoc.py. Specifically, this allows for querying the type
532 of an object against these built-in types and more importantly, for getting
533 their docstrings printed in the interactive interpreter's help() function.

538
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000539- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
540 a socket operation on a socket with a timeout, the exception will be
541 caught correctly. Previously, the exception was not caught.
542
Thomas Heller1393d6a2006-07-28 21:43:20 +0000543- Patch #1529514: The _ctypes extension is now compiled on more
544 openbsd target platforms.
545
Tim Peters9cab5932006-07-28 00:30:00 +0000546- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
547 a memory leak, affecting pickles and deep copies.
548
Tim Petersbc24eee2006-07-27 01:14:53 +0000549- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000550 Paul Eggert.
551
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000552- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
553
Thomas Hellerce049a02006-07-14 17:51:14 +0000554- Patch #1521817: Index range checking on ctypes arrays containing
555 exactly one element enabled again. This allows iterating over these
556 arrays, without the need to check the array size before.
557
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000558- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000559 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000560 /dev/null in certain cases; this is now fixed.
561
Thomas Heller47d7a062006-07-12 08:43:47 +0000562- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
563 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000564
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000565- Because of a misspelled preprocessor symbol, ctypes was always
566 compiled without thread support; this is now fixed.
567
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000568- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
569 methods now allow their database parameter to be None as the
570 sleepycat API allows.
571
Matt Flemingec926502006-07-28 11:27:27 +0000572- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
573 bluetooth API compared with Linux and FreeBSD.
574
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000575Tests
576-----
577
578- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
579 how long the test file should take to play. Now accepts taking 2.93 secs
580 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
581
Georg Brandl4793aa32006-07-28 18:31:39 +0000582- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
583 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
584 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000591Mac
592---
593
594- PythonLauncher now works correctly when the path to the script contains
595 characters that are treated specially by the shell (such as quotes).
596
597- Bug #1527397: PythonLauncher now launches scripts with the working directory
598 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000599 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000600 expect.

608Core and builtins
609-----------------
610
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000611- Bug #1441486: The literal representation of -(sys.maxint - 1)
612 again evaluates to a int object, not a long.
613
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000614- Bug #1501934: The scope of global variables that are locally assigned
615 using augmented assignment is now correctly determined.
616
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000617- Bug #927248: Recursive method-wrapper objects can now safely
618 be released.
619
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000620- Bug #1417699: Reject locale-specific decimal point in float()
621 and atof().
622
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000623- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
624 omit a default "error" argument for NULL pointer. This allows
625 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000626
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000627- Bug #1519018: 'as' is now validated properly in import statements.
628
Neal Norwitz28746ab2006-07-09 22:14:42 +0000629- On 64 bit systems, int literals that use less than 64 bits are
630 now ints rather than longs.
631
Neal Norwitzed657552006-07-10 00:04:44 +0000632- Bug #1512814, Fix incorrect lineno's when code at module scope
633 started after line 256.
634
Tim Peters32a83612006-07-10 21:08:24 +0000635- New function ``sys._current_frames()`` returns a dict mapping thread
636 id to topmost thread stack frame. This is for expert use, and is
637 especially useful for debugging application deadlocks. The functionality
638 was previously available in Fazal Majid's ``threadframe`` extension
639 module, but it wasn't possible to do this in a wholly threadsafe way from
640 an extension.

643-------
644
Martin v. Löwis77621582006-07-30 13:27:31 +0000645- Bug #1257728: Mention Cygwin in distutils error message about a missing
646 VS 2003.
647
Martin v. Löwis06c68b82006-07-10 22:11:28 +0000648- Patch #1519566: Update turtle demo, make begin_fill idempotent.
649
Tim Peters32a83612006-07-10 21:08:24 +0000650- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000651 environment variable to be set in order to the SDK environment
652 for finding the compiler, include files, etc.
653
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000654- Bug #1515998: Properly generate logical ids for files in bdist_msi.

Nick Coghlan2d792252006-07-06 13:47:18 +0000656- warnings.py now ignores ImportWarning by default
657
Thomas Woutersadd19112006-07-05 11:03:49 +0000658- string.Template() now correctly handles tuple-values. Previously,
659 multi-value tuples would raise an exception and single-value tuples would
660 be treated as the value they contain, instead.
661
Martin v. Löwisede77f52006-07-03 13:01:35 +0000662- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
663 even if some data are received.

669 degrees and radians.
670
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000671- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000672 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000673
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000674- Bug #1514703: Only setup canvas window in turtle when the canvas
675 is created.
676
Martin v. Löwis7596e832006-07-01 15:33:37 +0000677- Bug #1513223: .close() of a _socketobj now releases the underlying
678 socket again, which then gets closed as it becomes unreferenced.
679
Fred Drake10497c82006-06-29 02:57:48 +0000680- Bug #1504333: Make sgmllib support angle brackets in quoted
681 attribute values.
682
683- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
684 sgmllib ('[' and ']' were not accepted).
685
Georg Brandl1be63af2006-06-28 20:23:25 +0000686- Fix a bug in the turtle module's end_fill function.
687
Brett Cannon53ab5b72006-06-22 16:49:14 +0000688- Bug #1510580: The 'warnings' module improperly required that a Warning
689 category be either a types.ClassType and a subclass of Warning. The proper
690 check is just that it is a subclass with Warning as the documentation states.
691
Georg Brandlad29e632006-06-21 17:45:17 +0000692- The compiler module now correctly compiles the new try-except-finally
693 statement (bug #1509132).
694
Neal Norwitz60373cd2006-06-22 06:30:50 +0000695- The wsgiref package is now installed properly on Unix.
696
Vinay Sajip28e57612006-07-01 10:45:20 +0000697- A bug was fixed in logging.config.fileConfig() which caused a crash on
698 shutdown when fileConfig() was called multiple times.
699
Gerhard Häring762fbd32006-07-02 17:48:30 +0000700- The sqlite3 module did cut off data from the SQLite database at the first
701 null character before sending it to a custom converter. This has been fixed
702 now.
703
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000704Extension Modules
705-----------------
706
Tim Peters112aad32006-07-19 00:03:19 +0000707- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
708 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
709 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000710
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000711- Assigning None to pointer type fields in ctypes structures possible
712 overwrote the wrong fields, this is fixed now.
713
714- Fixed a segfault in _ctypes when ctypes.wintypes were imported
715 on non-Windows platforms.
716
717- Bug #1518190: The ctypes.c_void_p constructor now accepts any
718 integer or long, without range checking.
719
720- Patch #1517790: It is now possible to use custom objects in the ctypes
721 foreign function argtypes sequence as long as they provide a from_param
722 method, no longer is it required that the object is a ctypes type.
723
724- The '_ctypes' extension module now works when Python is configured
725 with the --without-threads option.
726
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000727- Bug #1513646: os.access on Windows now correctly determines write
728 access, again.
729
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000730- Bug #1512695: cPickle.loads could crash if it was interrupted with
731 a KeyboardInterrupt.
732
Neal Norwitza12aa882006-07-06 06:45:08 +0000733- Bug #1296433: parsing XML with a non-default encoding and
734 a CharacterDataHandler could crash the interpreter in pyexpat.
735
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000736- Patch #1516912: improve Modules support for OpenVMS.
737
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000738Build
739-----
740
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000741- Automate Windows build process for the Win64 SSL module.
742
Tim Peters32a83612006-07-10 21:08:24 +0000743- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000744 Previously, the slight difference could cause compilation errors of the
745 'zlib' module on systems with more than one version of zlib.
746
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000747- The MSI compileall step was fixed to also support a TARGETDIR
748 with spaces in it.
749
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000750- Bug #1517388: sqlite3.dll is now installed on Windows independent
751 of Tcl/Tk.
752
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000753- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000754 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +0000756Tests
757-----
758
759- Call os.waitpid() at the end of tests that spawn child processes in order
760 to minimize resources (zombies).
761
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000762Documentation
763-------------
764
Nick Coghlan2d792252006-07-06 13:47:18 +0000765- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
766 documentation for the warnings module.
767
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000768- Patch #1509163: MS Toolkit Compiler no longer available.
769
Neal Norwitz56640df2006-07-10 02:36:41 +0000770- Patch #1504046: Add documentation for xml.etree.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000777
778Core and builtins
779-----------------
780
Georg Brandla56b9152006-06-19 06:35:54 +0000781- Patch #1507676: Error messages returned by invalid abstract object operations
782 (such as iterating over an integer) have been improved and now include the
783 type of the offending object to help with debugging.
784
Brett Cannonea3912b2006-06-13 21:46:41 +0000785- Bug #992017: A classic class that defined a __coerce__() method that returned
786 its arguments swapped would infinitely recurse and segfault the interpreter.
787
Neal Norwitz909eb122006-06-12 02:13:21 +0000788- Fix the socket tests so they can be run concurrently.
789
Neal Norwitzb9845e72006-06-12 02:11:18 +0000790- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000791 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000792
Brett Cannon22565aa2006-06-09 22:31:23 +0000793- Bug #532646: object.__call__() will continue looking for the __call__
794 attribute on objects until one without one is found. This leads to recursion
795 when you take a class and set its __call__ attribute to an instance of the
796 class. Originally fixed for classic classes, but this fix is for new-style.
797 Removes the infinite_rec_3 crasher.
798
Georg Brandl24250812006-06-09 18:45:48 +0000799- The string and unicode methods startswith() and endswith() now accept
800 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
801
Brett Cannonde3b0522006-06-08 17:00:45 +0000802- Buffer objects, at the C level, never used the char buffer
803 implementation even when the char buffer for the wrapped object was
804 explicitly requested (originally returned the read or write buffer).
805 Now a TypeError is raised if the char buffer is not present but is
806 requested.
807
Georg Brandlddbaa662006-06-04 21:56:52 +0000808- Patch #1346214: Statements like "if 0: suite" are now again optimized
809 away like they were in Python 2.4.
810
Georg Brandlb7c8f542006-05-27 12:30:25 +0000811- Builtin exceptions are now full-blown new-style classes instead of
812 instances pretending to be classes, which speeds up exception handling
813 by about 80% in comparison to 2.5a2.
814
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000815- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
816 Unicode 4.1.
817
Georg Brandlf4ef1162006-05-26 18:03:31 +0000818- Patch #921466: sys.path_importer_cache is now used to cache valid and
819 invalid file paths for the built-in import machinery which leads to
820 fewer open calls on startup.
821
Tim Peters696cf432006-05-24 21:10:40 +0000822- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
823 of-2 bases. The largest speedup is for inputs with about 1000 decimal
824 digits. Conversion from non-power-of-2 bases remains quadratic-time in
825 the number of input digits (it was and remains linear-time for bases
826 2, 4, 8, 16 and 32).
827
Tim Petersb713ec22006-05-23 18:45:30 +0000828- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
829 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
830 an integer close to ``sys.maxint``. This was repaired by patch
831 #1335972, which also gives a nice speedup.
832
Richard Jonescebbefc2006-05-23 18:28:17 +0000833- Patch #1337051: reduced size of frame objects.
834
835- PyErr_NewException now accepts a tuple of base classes as its
836 "base" parameter.
837
Richard Jones7c88dcc2006-05-23 10:37:38 +0000838- Patch #876206: function call speedup by retaining allocated frame
839 objects.
840
Georg Brandl7b90e162006-05-18 07:01:27 +0000841- Bug #1462152: file() now checks more thoroughly for invalid mode
842 strings and removes a possible "U" before passing the mode to the
843 C library function.
844
Neal Norwitz1004a532006-05-15 07:17:23 +0000845- Patch #1488312, Fix memory alignment problem on SPARC in unicode
846
Neal Norwitz373f0a72006-05-15 07:04:36 +0000847- Bug #1487966: Fix SystemError with conditional expression in assignment
848
Martin v. Löwis879768d2006-05-11 13:28:43 +0000849- WindowsError now has two error code attributes: errno, which carries
850 the error values from errno.h, and winerror, which carries the error
851 values from winerror.h. Previous versions put the winerror.h values
852 (from GetLastError()) into the errno attribute.
853
Martin v. Löwis77736712006-05-04 05:51:03 +0000854- Patch #1475845: Raise IndentationError for unexpected indent.
855
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000856- Patch #1479181: split open() and file() from being aliases for each other.
857
Tim Peters44bd9862006-06-01 13:49:23 +0000858- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
859 methods were always silently ignored by dictionaries when comparing keys.
860 They are now passed through (except when using the C API function
861 ``PyDict_GetItem()``, whose semantics did not change).
862
863- Bug #1456209: In some obscure cases it was possible for a class with a
864 custom ``__eq__()`` method to confuse dict internals when class instances
865 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
866 No, you don't have any code that did this ;-)

872
873- Patch #1462338: Upgrade pyexpat to expat 2.0.0
874
Brett Cannon6ee7d012006-06-08 16:23:04 +0000875- Change binascii.hexlify to accept a read-only buffer instead of only a char
876 buffer and actually follow its documentation.
877
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000878- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
879
Nick Coghlanc649ec52006-05-29 12:43:05 +0000880- Patch #1478788 (modified version): The functional extension module has
881 been renamed to _functools and a functools Python wrapper module added.
882 This provides a home for additional function related utilities that are
883 not specifically about functional programming. See PEP 309.
884
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000885- Patch #1493701: performance enhancements for struct module.
886

888
Georg Brandl8d3342b2006-05-16 07:38:27 +0000889- Patch #1435422: zlib's compress and decompress objects now have a
890 copy() method.
891
Andrew MacIntyre92913322006-06-13 15:04:24 +0000892- Patch #1454481: thread stack size is now tunable at runtime for thread
893 enabled builds on Windows and systems with Posix threads support.
894
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000895- On Win32, os.listdir now supports arbitrarily-long Unicode path names
896 (up to the system limit of 32K characters).
897
898- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
899 As a result, these functions now raise WindowsError instead of OSError.
900
Tim Peters7a822da2006-05-25 21:50:17 +0000901- ``time.clock()`` on Win64 should use the high-performance Windows
902 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
903 Windows platforms).
904
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000905- Calling Tk_Init twice is refused if the first call failed as that
906 may deadlock.
907
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000908- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
909 accept it without potentially using an uninitialized pointer.
910
911- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
912 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smith372b5832006-06-05 18:48:21 +0000915- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000916 [pybsddb project SF patch number 1466734]
917
Gregory P. Smith372b5832006-06-05 18:48:21 +0000918- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
919 parameter is supplied. [SF pybsddb bug #1477863]
920
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000921- bsddb: the __len__ method of a DB object has been fixed to return correct
922 results. It could previously incorrectly return 0 in some cases.
923 Fixes SF bug 1493322 (pybsddb bug 1184012).
924
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000925- bsddb: the bsddb.dbtables Modify method now raises the proper error and
926 aborts the db transaction safely when a modifier callback fails.
927 Fixes SF python patch/bug #1408584.
928
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000929- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000930 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000931 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
932 database calls that would previously deadlock. [SF python bug #775414]
933

Georg Brandl83cc0d02006-06-14 08:50:03 +0000955- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
956 mime.types file for determining MIME types.
957
Georg Brandl2605ca82006-06-14 06:08:31 +0000958- Bug #1339007: Shelf objects now don't raise an exception in their
959 __del__ method when initialization failed.
960
Martin v. Löwisd8251432006-06-14 05:21:04 +0000961- Patch #1455898: The MBCS codec now supports the incremental mode for
962 double-byte encodings.
963
Tim Peters43898b42006-06-14 04:09:25 +0000964- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
965 guarantee that adjacent triples in the return list always describe
966 non-adjacent blocks. Previously, a pair of matching blocks could end
967 up being described by multiple adjacent triples that formed a partition
968 of the matching pair.
969
Greg Ward0e0c9f42006-06-11 16:24:11 +0000970- Bug #1498146: fix optparse to handle Unicode strings in option help,
971 description, and epilog.
972
Greg Wardd1c797e2006-06-11 14:42:41 +0000973- Bug #1366250: minor optparse documentation error.
974
Greg Ward7f547402006-06-11 00:40:49 +0000975- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
976 clarify docs.
977
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000978- The wsgiref package has been added to the standard library.
979
Nick Coghlan676725d2006-06-08 13:54:49 +0000980- The functions update_wrapper() and wraps() have been added to the functools
981 module. These make it easier to copy relevant metadata from the original
982 function when writing wrapper functions.
983
Tim Petersd6a9eef2006-06-05 01:48:21 +0000984- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
985 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000986
Martin v. Löwis3f767792006-06-04 19:36:28 +0000987- Patch #1359618: Speed up charmap encoder by using a trie structure
988 for lookup.
989
Tim Petersd609b1a2006-06-02 23:22:51 +0000990- The functions in the ``pprint`` module now sort dictionaries by key
991 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
992 if and only if its display required more than one line, although that
993 wasn't documented. The new behavior increases predictability; e.g.,
994 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
995
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000996- Patch #1497027: try HTTP digest auth before basic auth in urllib2
997 (thanks for J. J. Lee).
998
Georg Brandl2b330372006-05-28 20:23:12 +0000999- Patch #1496206: improve urllib2 handling of passwords with respect to
1000 default HTTP and HTTPS ports.
1001
George Yoshidaf3c65de2006-05-28 16:39:09 +00001002- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1003
Bob Ippolito7298f272006-05-23 18:43:47 +00001004- Patch #1281707: speed up gzip.readline.
1005
Georg Brandlb89316f2006-05-17 15:51:16 +00001006- Patch #1180296: Two new functions were added to the locale module:
1007 format_string() to get the effect of "format % items" but locale-aware,
1008 and currency() to format a monetary number with currency sign.
1009
Georg Brandle3a25832006-05-17 14:56:04 +00001010- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1011 and several features added, such as speed and geometry control.
1012
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001013- Patch #1488881: add support for external file objects in bz2 compressed
1014 tarfiles.
1015
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001016- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1017 stdout arguments, making it possible to redirect input and output
1018 for remote debugging.
1019
1020- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1021 a couple of issues, notably handling of long file names using the
1022 GNU LONGNAME extension.
1023
1024- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1025 new flag when ``name`` is already the name of an option flag.
1026
1027- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1028 package.
1029
1030- Patch #1472854: make the rlcompleter.Completer class usable on non-
1031 UNIX platforms.
1032
1033- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1034
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001035- Bug #1472827: correctly escape newlines and tabs in attribute values in
1036 the saxutils.XMLGenerator class.

1072-----------------
1073
Thomas Heller1b046642006-04-18 18:51:06 +00001074- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1075 by converting these apis from macros into exported functions again:
1076
1077 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1078 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1079 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

1081 PyRun_String Py_CompileString
1082
Martin v. Löwis45294a92006-04-18 06:24:08 +00001083- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1084
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001085- All uses of PyStructSequence_InitType have been changed to initialize
1086 the type objects only once, even if the interpreter is initialized
1087 multiple times.
1088
Neal Norwitz61546162006-04-14 05:20:28 +00001089- Bug #1454485, array.array('u') could crash the interpreter. This was
1090 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1091 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1092
1093- Py_UNICODE is unsigned. It was always documented as unsigned, but
1094 due to a bug had a signed value in previous versions.
1095
Tim Peters3a5e8b12006-04-11 01:44:07 +00001096- Patch #837242: ``id()`` of any Python object always gives a positive
1097 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1098 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001099 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001100 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001101
Tim Peters3a5e8b12006-04-11 01:44:07 +00001102 def __hash__(self):
1103 return id(self) # WRONG
1104
1105 because a hash result must be a (short) Python int but it was always
1106 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001107 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001108 was always usable as a hash value before this patch. That's no longer
1109 necessarily so.
1110
1111- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001112 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001113 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001114 #1454844)
1115
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001116- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1117 involving generators that have paused outside of any ``try`` or ``with``
1118 blocks. (In 2.5a1, a paused generator that was part of a reference
1119 cycle could not be garbage collected, regardless of whether it was
1120 paused in a ``try`` or ``with`` block.)

Tim Peters711bf302006-04-25 03:31:36 +00001152- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1153 a doctest to be skipped (the code is not run, and the expected output
1154 or exception is ignored).
1155
Nick Coghlanda2268f2006-04-24 04:37:15 +00001156- Fixed contextlib.nested to cope with exceptions being raised and
1157 caught inside exit handlers.
1158
Greg Wardab05edc2006-04-23 03:47:58 +00001159- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1160 hex, octal, or binary; add ``append_const`` action; keep going if
1161 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1162 added ``epilog`` for better help generation).
1163
Tim Peters21fbd572006-04-21 21:18:10 +00001164- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1165 called from a thread spawned as a side effect of importing a module.
1166
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001167- The pydoc module now supports documenting packages contained in
1168 .zip or .egg files.
1169
1170- The pkgutil module now has several new utility functions, such
1171 as ``walk_packages()`` to support working with packages that are either
1172 in the filesystem or zip files.
1173
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001174- The mailbox module can now modify and delete messages from
1175 mailboxes, in addition to simply reading them. Thanks to Gregory
1176 K. Johnson for writing the code, and to the 2005 Google Summer of
1177 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001178
Tim Petersc7605f22006-04-17 21:12:33 +00001179- The ``__del__`` method of class ``local`` in module ``_threading_local``
1180 returned before accomplishing any of its intended cleanup.
1181
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001182- Patch #790710: Add breakpoint command lists in pdb.

Martin v. Löwis0f48d982006-04-14 14:34:26 +00001218 CXX from --with-cxx-main, see description in README.
1219
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001220- Patch #1429775: Link extension modules with the shared libpython.
1221
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001222- Fixed a libffi build problem on MIPS systems.
1223
Tim Peters8931ff12006-05-13 23:28:20 +00001224- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1225 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1226 and "%zu" for unsigned integers of type ``size_t``.
1227
Anthony Baxter51bcb682006-04-05 14:51:42 +00001228Tests
1229-----
1230
Nick Coghlanda2268f2006-04-24 04:37:15 +00001231- test_contextlib now checks contextlib.nested can cope with exceptions
1232 being raised and caught inside exit handlers.
1233
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001234- test_cmd_line now checks operation of the -m and -c command switches
1235
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001236- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1237 it separately and by hand. It also wasn't cleaning up its changes to
1238 the current Decimal context.
1239
Thomas Woutersabd08882006-04-26 15:53:30 +00001240- regrtest.py now has a -M option to run tests that test the new limits of
1241 containers, on 64-bit architectures. Running these tests is only sensible
1242 on 64-bit machines with more than two gigabytes of memory. The argument
1243 passed is the maximum amount of memory for the tests to use.
1244
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001245Tools

1247
1248- Added the Python benchmark suite pybench to the Tools/ directory;
1249 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001251Documentation
1252-------------
1253
Tim Petersb06d28c2006-05-12 01:57:59 +00001254- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1255
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001256- PEP 343: Added Context Types section to the library reference
1257 and attempted to bring other PEP 343 related documentation into
1258 line with the implementation and/or python-dev discussions.
1259
Tim Peters8dc73d22006-04-24 02:03:16 +00001260- Bug #1337990: clarified that ``doctest`` does not support examples
1261 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001264What's New in Python 2.5 alpha 1?
1265=================================
1266
Anthony Baxterebed3f62006-04-03 15:03:44 +00001267*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001268
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001269Core and builtins
1270-----------------
1271
Nick Coghlan43832302006-04-23 17:04:07 +00001272- PEP 338: -m command line switch now delegates to runpy.run_module
1273 allowing it to support modules in packages and zipfiles
1274
Martin v. Löwisc661b882006-04-20 04:54:23 +00001275- On Windows, .DLL is not an accepted file name extension for
1276 extension modules anymore; extensions are only found if they
1277 end in .PYD.
1278
Martin v. Löwisea62d252006-04-03 10:56:49 +00001279- Bug #1421664: sys.stderr.encoding is now set to the same value as
1280 sys.stdout.encoding.
1281
Neal Norwitz92e212f2006-04-03 04:48:37 +00001282- __import__ accepts keyword arguments.
1283
Georg Brandlccadf842006-03-31 18:54:53 +00001284- Patch #1460496: round() now accepts keyword arguments.
1285
Anthony Baxter262c00a2006-03-30 10:53:17 +00001286- Fixed bug #1459029 - unicode reprs were double-escaped.
1287
Hye-Shik Changd478f342006-03-23 12:32:36 +00001288- Patch #1396919: The system scope threads are reenabled on FreeBSD
1289 5.4 and later versions.
1290
Neal Norwitze98ccf62006-03-23 05:39:47 +00001291- Bug #1115379: Compiling a Unicode string with an encoding declaration
1292 now gives a SyntaxError.
1293
Georg Brandlabd1ff82006-03-18 07:59:59 +00001294- Previously, Python code had no easy way to access the contents of a
1295 cell object. Now, a ``cell_contents`` attribute has been added
1296 (closes patch #1170323).
1297
Tim Peterscf79aac2006-03-16 01:14:46 +00001298- Patch #1123430: Python's small-object allocator now returns an arena to
1299 the system ``free()`` when all memory within an arena becomes unused
1300 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1301 freed. Some applications will see a drop in virtual memory size now,
1302 especially long-running applications that, from time to time, temporarily
1303 use a large number of small objects. Note that when Python returns an
1304 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001305 platform C library will in turn return that memory to the operating system.
1306 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001307 appears to be effective at least on Microsoft C and gcc-based systems.
1308 Thanks to Evan Jones for hard work and patience.
1309
Georg Brandl533ff6f2006-03-08 18:09:27 +00001310- Patch #1434038: property() now uses the getter's docstring if there is
1311 no "doc" argument given. This makes it possible to legitimately use
1312 property() as a decorator to produce a read-only property.
1313
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001314- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1315 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1316 of requiring an int or long in slicing and a few other contexts, enabling
1317 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1318
Neal Norwitz995acdf2006-03-07 05:01:00 +00001319- Fixed various bugs reported by Coverity's Prevent tool.
1320
Brett Cannonbf364092006-03-01 04:25:17 +00001321- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1322 new exception base class, BaseException, which has a new message attribute.
1323 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1324 Raising a string exception now raises a DeprecationWarning.
1325
Thomas Woutersfb609f42006-02-28 16:37:25 +00001326- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1327 explicitly relative, using 'from .module import name' to mean 'from the same
1328 package as this module is in. Imports without dots still default to the
1329 old relative-then-absolute, unless 'from __future__ import
1330 absolute_import' is used.
1331
Brett Cannona7446e32006-02-27 23:39:10 +00001332- Properly check if 'warnings' raises an exception (usually when a filter set
1333 to "error" is triggered) when raising a warning for raising string
1334 exceptions.
1335
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001336- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001337 The name was removed from Include/code.h.
1338
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001339- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001340
Guido van Rossum1968ad32006-02-25 22:38:04 +00001341- Patch 1433928:
1342 - The copy module now "copies" function objects (as atomic objects).
1343 - dict.__getitem__ now looks for a __missing__ hook before raising
1344 KeyError.
1345
Tim Peters84ef21c2006-02-28 20:39:06 +00001346- PEP 343: with statement implemented. Needs ``from __future__ import
1347 with_statement``. Use of 'with' as a variable will generate a warning.
1348 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001349 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001350 The following objects have __context__ methods:
1351 - The built-in file type.
1352 - The thread.LockType type.
1353 - The following types defined by the threading module:
1354 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1355 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001356
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001357- Fix the encodings package codec search function to only search
1358 inside its own package. Fixes problem reported in patch #1433198.
1359
1360 Note: Codec packages should implement and register their own
1361 codec search function. PEP 100 has the details.
1362
Tim Peters9ea89d22006-06-04 03:26:02 +00001363- PEP 353: Using ``Py_ssize_t`` as the index type.
1364
1365- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1366 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1367 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1368 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1369 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001370
Neal Norwitzfc76d632006-01-10 06:03:13 +00001371- Patch #1400181, fix unicode string formatting to not use the locale.
1372 This is how string objects work. u'%f' could use , instead of .
1373 for the decimal point. Now both strings and unicode always use periods.
1374
Neal Norwitz671b9e32006-01-09 07:07:12 +00001375- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1376 configure would break checking curses.h.
1377
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001378- Bug #959576: The pwd module is now builtin. This allows Python to be
1379 built on UNIX platforms without $HOME set.
1380
Neal Norwitzc10978f2005-12-19 06:07:16 +00001381- Bug #1072182, fix some potential problems if characters are signed.
1382
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001383- Bug #889500, fix line number on SyntaxWarning for global declarations.
1384
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001385- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1386
Neal Norwitze7214a12005-12-18 05:03:17 +00001387- Support for converting hex strings to floats no longer works.
1388 This was not portable. float('0x3') now raises a ValueError.
1389
Barry Warsaw2a38a862005-12-18 01:27:35 +00001390- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001391 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001392 is now displayed in interactive prompt banner.
1393
Georg Brandlfa166682005-12-17 21:45:17 +00001394- Implementation of PEP 341 - Unification of try/except and try/finally.
1395 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001396 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001397
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001398- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1399 now encodes backslash correctly.
1400
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001401- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1402
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001403- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001404 and long longs.
1405
Neal Norwitz67715f02005-11-09 06:59:35 +00001406- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001407 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001408 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001409
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001410- Replaced most Unicode charmap codecs with new ones using the
1411 new Unicode translate string feature in the builtin charmap
1412 codec; the codecs were created from the mapping tables available
1413 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1414 encodings now include a mapping for the Apple logo)
1415
Tim Peterse3547fd2005-12-16 23:13:57 +00001416- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001417
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001418- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001419
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001420- A new AST parser implementation was completed. The abstract
1421 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001422 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001423
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001424- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001425 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1426
Neal Norwitz708e51a2005-10-03 04:48:15 +00001427- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1428
Neal Norwitz11bd1192005-10-03 00:54:56 +00001429- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1430 Provide a warning when a directory is passed on the command line.
1431
Neal Norwitz40d37812005-10-02 01:48:49 +00001432- Fix segfault with invalid coding.
1433
1434- SF bug #772896: unknown encoding results in MemoryError.
1435
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001436- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001437 supported a __len__() method which evaluated to False when the iterator
1438 was empty.
1439
Guido van Rossum630db602005-09-20 18:49:54 +00001440- On 64-bit platforms, when __len__() returns a value that cannot be
1441 represented as a C int, raise OverflowError.
1442
Skip Montanarof8948ca2005-09-19 03:54:46 +00001443- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001444 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001445
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001446- SF bug #893549: parsing keyword arguments was broken with a few format
1447 codes.
1448
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001449- Changes donated by Elemental Security to make it work on AIX 5.3
1450 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1451 bug #105470: test_pwd fails on 64bit system (Opteron).
1452
Guido van Rossum539c6622005-09-14 17:49:54 +00001453- Changes donated by Elemental Security to make it work on HP-UX 11 on
1454 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1455
Georg Brandl4550b8d2005-08-26 06:43:52 +00001456- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001457 (fixes bug #1119418).
1458
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001459- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1460
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001461- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1462 exceptions that cause a function to exit.
1463
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001464- The implementation of set() and frozenset() was revised to use its
1465 own internal data structure. Memory consumption is reduced by 1/3
1466 and there are modest speed-ups as well. The API is unchanged.
1467
Tim Petersde7990b2005-07-17 23:45:23 +00001468- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1469
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001470- SF bug #1229429: PyObject_CallMethod failed to decrement some
1471 reference counts in some error exit cases.
1472
Tim Petersecc6e6a2005-07-10 22:30:55 +00001473- SF bug #1185883: Python's small-object memory allocator took over
1474 a block managed by the platform C library whenever a realloc specified
1475 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001476 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001477 portable way to copy data from the C-managed block into Python's
1478 small-object space without risking a memory fault. Python's small-object
1479 realloc now leaves such blocks under the control of the platform C
1480 realloc.
1481
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001482- SF bug #1232517: An overflow error was not detected properly when
1483 attempting to convert a large float to an int in os.utime().
1484
Raymond Hettinger3296e692005-06-29 23:29:56 +00001485- SF bug #1224347: hex longs now print with lowercase letters just
1486 like their int counterparts.
1487
Michael W. Hudson188d4362005-06-20 16:52:57 +00001488- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1489 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1490 interpreter states; back out that fix and do a better job (see
1491 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1492 for a longer write-up of the problem).
1493
Michael W. Hudsondf888462005-06-03 14:41:55 +00001494- SF patch #1180995: marshal now uses a binary format by default when
1495 serializing floats.
1496
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001497- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1498 the routines that promise to produce IEEE 754 binary representations
1499 of floats now simply copy bytes around.
1500
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001501- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1502 278.
1503
Brett Cannonc3647ac2005-04-26 03:45:26 +00001504- patch #1109424: int, long, float, complex, and unicode now check for the
1505 proper magic slot for type conversions when subclassed. Previously the
1506 magic slot was ignored during conversion. Semantics now match the way
1507 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001508 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001509 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001510 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001511
Barry Warsawc8d907c2005-04-19 23:43:40 +00001512- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1513 NULL, now raise an AttributeError when attempting to set or delete the
1514 attribute. Previously a TypeError was raised, but this was inconsistent
1515 with the equivalent pure-Python implementation.
1516
Michael W. Hudson774479c2005-04-18 08:46:17 +00001517- It is now safe to call PyGILState_Release() before
1518 PyEval_InitThreads() (note that if there is reason to believe there
1519 are multiple threads around you still must call PyEval_InitThreads()
1520 before using the Python API; this fix is for extension modules that
1521 have no way of knowing if Python is multi-threaded yet).
1522
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001523- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1524 disabled caused a crash.
1525
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001526- Bug #1165306: instancemethod_new allowed the creation of a method
1527 with im_class == im_self == NULL, which caused a crash when called.
1528
Tim Petersecc6e6a2005-07-10 22:30:55 +00001529- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001530 fixes the crash seen in bug #1165761
1531
Raymond Hettinger96229b12005-03-11 06:49:40 +00001532- Added two new builtins, any() and all().
1533
Brett Cannon409d8f22005-03-05 06:47:57 +00001534- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001535 (e.g., ``class C(): pass`` is no longer a syntax error).
1536 Patch #1176012 added support to the 'parser' module and 'compiler' package
1537 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001538
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001539- Patch #1115086: Support PY_LONGLONG in structmember.
1540
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001541- Bug #1155938: new style classes did not check that __init__() was
1542 returning None.
1543
Tim Petersecc6e6a2005-07-10 22:30:55 +00001544- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001545 ('\') with a specific error message.
1546
Martin v. Löwisff232d72005-03-03 09:24:38 +00001547- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1548
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001549- Bug #1124295: the __name__ attribute of file objects was
1550 inadvertently made inaccessible in restricted mode.
1551
Tim Petersecc6e6a2005-07-10 22:30:55 +00001552- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001553 an ferror() call.
1554
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001555- min() and max() now support key= arguments with the same meaning as in
1556 list.sort().
1557
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001558- The peephole optimizer now performs simple constant folding in expressions:
1559 (2+3) --> (5).
1560
Raymond Hettingera422c342005-01-11 03:03:27 +00001561- set and frozenset objects can now be marshalled. SF #1098985.
1562
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001563- Bug #1077106: Poor argument checking could cause memory corruption
1564 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001565
Jeremy Hyltonab630502005-02-04 18:44:06 +00001566- The parser did not complain about future statements in illegal
1567 positions. It once again reports a syntax error if a future
1568 statement occurs after anything other than a doc string.
1569
Neil Schemenauercf52c072005-08-12 17:34:58 +00001570- Change the %s format specifier for str objects so that it returns a
1571 unicode instance if the argument is not an instance of basestring and
1572 calling __str__ on the argument returns a unicode instance.
1573
Tim Petersf4e69282006-02-27 17:15:31 +00001574- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1575 current thread state when the auto-GIL-state machinery knows about
1576 it (since the thread state is being deleted, continuing to remember it
1577 can't help, but can hurt if another thread happens to get created with
1578 the same thread id).
1579
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001580Extension Modules

1605
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001606- The unicodedata module was updated to the 4.1 version of the Unicode
1607 database. The 3.2 version is still available as unicodedata.db_3_2_0
1608 for applications that require this specific version (such as IDNA).
1609
Neal Norwitzb62c4332006-03-04 18:35:47 +00001610- The timing module is no longer built by default. It was deprecated

1756
Raymond Hettingerb2594052004-12-05 09:25:51 +00001757- itertools.islice() now accepts None for the start and step arguments.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001770- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1771 been renamed to have only a single underscore prefix. This was done to
1772 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001773
Nick Coghlan43832302006-04-23 17:04:07 +00001774- PEP 338: new module runpy defines a run_module function to support
1775 executing modules which provide access to source code or a code object
1776 via the PEP 302 import mechanisms.
1777
Anthony Baxter93f5b932006-04-03 08:05:07 +00001778- The email module's parsedate_tz function now sets the daylight savings

1786 in attribute values.
1787
Anthony Baxterc51ee692006-04-01 00:57:31 +00001788- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001789 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001790 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001791 module will not be built.
1792
Tim Petersc17976e2006-04-01 00:26:53 +00001793- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1794 aren't officially supported here, and trying to use them will probably
1795 raise an exception some day. But dicts have been allowed, and "mostly
1796 worked", so support for them won't go away without warning.
1797
Georg Brandl338ef7d2006-03-31 18:42:16 +00001798- Bug #1445068: getpass.getpass() can now be given an explicit stream
1799 argument to specify where to write the prompt.
1800

1816
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001817- email 4.0 package now integrated. This is largely the same as the email 3.0
1818 package that was included in Python 2.3, except that PEP 8 module names are
1819 now used (e.g. mail.message instead of email.Message). The MIME classes
1820 have been moved to a subpackage (e.g. email.mime.text instead of
1821 email.MIMEText). The old names are still supported for now. Several
1822 deprecated Message methods have been removed and lots of bugs have been
1823 fixed. More details can be found in the email package documentation.
1824
Walter Dörwald40108c92006-03-27 08:15:44 +00001825- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1826 (a subclass of tuple) that provides incremental decoders and encoders
1827 (a way to use stateful codecs without the stream API). Python functions
1828 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1829 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1830 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001831
Walter Dörwald067db482006-03-15 22:17:27 +00001832- Patch #1359365: Calling next() on a closed StringIO.String object raises
1833 a ValueError instead of a StopIteration now (like file and cString.String do).
1834 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1835 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001836
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001837- A regrtest option -w was added to re-run failed tests in verbose mode.

1910 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1911 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1912 Ronald L. Rivest offered this advice for Python:
1913
1914 "The consensus of researchers in this area (at least as
1915 expressed at the NIST Hash Function Workshop 10/31/05),
1916 is that SHA-256 is a good choice for the time being, but
1917 that research should continue, and other alternatives may
1918 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001919
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001920- Added a subset of Fredrik Lundh's ElementTree package. Available

Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002016 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002017 the generate_tokens() function now accepts a callable argument that
2018 terminates by raising StopIteration.
2019
Georg Brandl9166e1a2005-06-04 09:20:03 +00002020- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2021
Georg Brandl268e61c2005-06-03 14:28:50 +00002022- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2023 component of the path.
2024
Skip Montanaro174dd222005-05-14 20:54:16 +00002025- Patch #1120353: The xmlrpclib module provides better, more transparent,
2026 support for datetime.{datetime,date,time} objects. With use_datetime set
2027 to True, applications shouldn't have to fiddle with the DateTime wrapper
2028 class at all.
2029
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002030- distutils.commands.upload was added to support uploading distribution
2031 files to PyPI.
2032
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002033- distutils.commands.register now encodes the data as UTF-8 before posting
2034 them to PyPI.
2035
Raymond Hettinger267b8682005-03-27 10:47:39 +00002036- decimal operator and comparison methods now return NotImplemented
2037 instead of raising a TypeError when interacting with other types. This
2038 allows other classes to implement __radd__ style methods and have them
2039 work as expected.
2040
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002041- Bug #1163325: Decimal infinities failed to hash. Attempting to
2042 hash a NaN raised an InvalidOperation instead of a TypeError.
2043
Tim Petersecc6e6a2005-07-10 22:30:55 +00002044- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002045 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2046
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002047- Patch #1043890: Add extractall method to tarfile.
2048
Martin v. Löwisc72dd382005-03-04 13:50:17 +00002049- Patch #1075887: Don't require MSVC in distutils if there is nothing
2050 to build.
2051
Martin v. Löwis637431b2005-03-03 23:12:42 +00002052- Patch #1103407: Properly deal with tarfile iterators when untarring
2053 symbolic links on Windows.
2054
Tim Petersecc6e6a2005-07-10 22:30:55 +00002055- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00002056 profile.py if available.
2057
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002058- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2059
Martin v. Löwisc5574e82005-03-03 10:57:37 +00002060- Patch #1117454: Remove code to special-case cookies without values
2061 in LWPCookieJar.
2062
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00002063- Patch #1117339: Add cookielib special name tests.
2064
Martin v. Löwise869eb12005-03-03 09:46:07 +00002065- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
2066
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00002067- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
2068
Martin v. Löwisdf241532005-03-03 08:17:42 +00002069- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
2070
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002071- Patch #1104111: Alter setup.py --help and --help-commands.
2072
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002073- Patch #1121234: Properly cleanup _exit and tkerror commands.
2074
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002075- Patch #1049151: xdrlib now unpacks booleans as True or False.
2076
Raymond Hettingerbab41432005-02-05 01:31:19 +00002077- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2078
Guido van Rossumd0641422005-02-03 15:01:24 +00002079- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2080 disables recursive traversal through instance attributes, which can
2081 be exploited in various ways.
2082
Tim Peterse3547fd2005-12-16 23:13:57 +00002083- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002084 flags on the HTTP listening socket.
2085
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002086- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2087 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2088
Fred Drakefbdeaad2006-07-29 16:56:15 +00002089- Patches #893642, #1039083: add allow_none, encoding arguments to
2090 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002091
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002092- Bug #1110478: Revert os.environ.update to do putenv again.
2093
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002094- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2095
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002096- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2097
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002098- Enhancements to the csv module:
2099
2100 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002101 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002102 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002103 + Dialect parameter parsing has been re-implemented to improve error
2104 reporting.
2105 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2106 dictates.
2107 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002108 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002109 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002110 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2111 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002112 + reader now allows \r characters to be quoted (previously it only allowed
2113 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002114 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002115 + Dialect classes passed to the module are no longer instantiated by
2116 the module before being parsed (the former validation scheme required
2117 this, but the mechanism was unreliable).
2118 + The dialect registry now contains instances of the internal
2119 C-coded dialect type, rather than references to python objects.
2120 + the internal c-coded dialect type is now immutable.
2121 + register_dialect now accepts the same keyword dialect specifications
2122 as the reader and writer, allowing the user to register dialects
2123 without first creating a dialect class.
2124 + a configurable limit to the size of parsed fields has been added -
2125 previously, an unmatched quote character could result in the entire
2126 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002127 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002128 the parser field size limit (returning the former limit). The initial
2129 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002130 + A line_num attribute has been added to the reader object, which tracks
2131 the number of lines read from the source iterator. This is not
2132 the same as the number of records returned, as records can span
2133 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002134 + reader and writer objects were not being registered with the cyclic-GC.
2135 This has been fixed.
2136
Brett Cannone6539c42005-01-08 02:43:53 +00002137- _DummyThread objects in the threading module now delete self.__block that is
2138 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2139 lock primitives tend to be limited in number and thus should not be wasted on
2140 a _DummyThread object. Fixes bug #1089632.
2141
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002142- The imghdr module now detects Exif files.
2143
Raymond Hettinger6065d322004-12-20 23:51:53 +00002144- StringIO.truncate() now correctly adjusts the size attribute.
2145 (Bug #951915).
2146
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002147- locale.py now uses an updated locale alias table (built using
2148 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2149 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002150 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002151
Raymond Hettinger3557f422004-12-07 12:02:02 +00002152- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2153
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002154- the pickle module no longer accepts the deprecated None option in the
2155 args tuple returned by __reduce__().
2156
Brett Cannon84667c02004-12-07 03:25:18 +00002157- optparse now optionally imports gettext. This allows its use in setup.py.
2158
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002159- the pickle module no longer uses the deprecated bin parameter.
2160
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002161- the shelve module no longer uses the deprecated binary parameter.
2162
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002163- the pstats module no longer uses the deprecated ignore() method.
2164
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002165- the filecmp module no longer uses the deprecated use_statcache argument.
2166
Raymond Hettinger664347b2004-12-04 21:21:53 +00002167- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2168 extended or overridden by subclasses. Formerly, the subclassed method would
2169 be ignored by the rest of the module. (Bug #1078905).
2170
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002171- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002172 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002173
Walter Dörwald36733692004-12-22 12:50:50 +00002174- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2175 once when a size argument is given. This prevents a buffer overflow in the
2176 tokenizer with very long source lines.
2177
Barry Warsaw538561e2006-01-01 21:48:54 +00002178- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2179 immediately after creating the object, without any intervening
2180 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002181
Skip Montanaro05885812005-01-16 20:48:27 +00002182- The reconvert.quote function can now emit triple-quoted strings. The
2183 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002184
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002185- ``UserString.MutableString`` now supports negative indices in
2186 ``__setitem__`` and ``__delitem__``
2187
Greg Ward40407942005-03-05 02:53:17 +00002188- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2189 correctly.
2190
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002191- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2192 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2193 character even if the user has passed a size parameter to get a proper
2194 line ending. Remove the special handling of a "\r\n" that has been split
2195 between two lines.
2196
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002197- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2198 about illegal code points. The codec now supports PEP 293 style error
2199 handlers.
2200
Walter Dörwald78a78b02005-09-01 12:04:29 +00002201- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002202 from the input stream, so that the output is a byte string in the correct
2203 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002204
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002205- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2206 considering it exactly like a '*'.
2207
Walter Dörwald007f8df2005-10-09 19:42:27 +00002208- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2209 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002210
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002211- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2212
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002213- Patch #1413711: Certain patterns of differences were making difflib
2214 touch the recursion limit.
2215
Walter Dörwald58917a62006-03-31 15:26:22 +00002216- Bug #947906: An object oriented interface has been added to the calendar
2217 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002218 called as a script (e.g. via ``python -mcalendar``). Localized month and
2219 weekday names can be ouput (even if an exotic encoding is used) using
2220 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002221

2229
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002230- Build support for Win64-AMD64 was added.
2231
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002232- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2233
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002234- Patch #881820: look for openpty and forkpty also in libbsd.
2235
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002236- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2237 The zlib module is now builtin on Windows.
2238
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002239- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2240
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002241- Bug #1189330: configure did not correctly determine the necessary
2242 value of LINKCC if python was built with GCC 4.0.
2243
Trent Mick8321b422005-07-26 02:29:21 +00002244- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2245 vulnerability in zlib 1.2.1 and 1.2.2.
2246
Brett Cannon08cd5982005-04-24 22:26:38 +00002247- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2248 flags that change binary compatibility. Changes were also made to
2249 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002250 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002251
Bob Ippolitoed233462005-03-29 13:47:59 +00002252- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2253 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2254 no longer exists). This configure patch makes things right.
2255
Martin v. Löwise2713be2005-03-08 15:03:08 +00002256- Bug #1158607: Build with --disable-unicode again.
2257
Brett Cannon46d96232005-02-16 00:07:19 +00002258- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2259 defined. Discovered as a result of not being able to build on OS X.
2260
Brett Cannon516592f2004-12-07 00:42:59 +00002261- setup.py now uses the directories specified in LDFLAGS using the -L option
2262 and in CPPFLAGS using the -I option for adding library and include
2263 directories, respectively, for compiling extension modules against. This has
2264 led to the core being compiled using the values in CPPFLAGS. It also removes
2265 the need for the special-casing of both DarwinPorts and Fink for darwin since
2266 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2267 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2268 Fink, ``-I/opt/local/include`` for DarwinPorts).
2269
Brett Cannon43802422005-02-10 20:48:03 +00002270- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2271 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2272 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2273 Closes bug #1096244. Thanks Gregory Bond.

2276-----
2277
Tim Petersc9d78aa2006-03-26 23:27:58 +00002278- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2279 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2280 is obtained via the ``PyObject_`` family, it must be released via the
2281 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2282 always been officially true, but when Python's small-object allocator was
2283 introduced, an attempt was made to cater to a few extension modules
2284 discovered at the time that obtained memory via ``PyObject_New`` but
2285 released it via ``PyMem_DEL``. It's years later, and if such code still
2286 exists it will fail now (probably with segfaults, but calling wrong
2287 low-level memory management functions can yield many symptoms).

Raymond Hettingerbeb31012005-08-16 03:47:52 +00002289- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002293- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2294 mapping argument now. This string is used as a mapping table. Byte values
2295 greater than the length of the string and 0xFFFE are treated as undefined
2296 mappings.
