170
Brett Cannon19d76c52006-09-09 07:18:44 +0000171- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

293Core and builtins
294-----------------
295
Neal Norwitz24b6f202006-09-05 04:43:56 +0000296- Fix infinite recursion when subclassing long and overriding __hash__.
297
298- Fix concatenation (+=) of long strings.
299
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000300- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000301 compared equal or unequal to a string and a UnicodeDecodeError
302 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000303
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000304 Instead, the equal (==) and unequal (!=) comparison operators will
305 now issue a UnicodeWarning and interpret the two objects as
306 unequal. The UnicodeWarning can be filtered as desired using
307 the warning framework, e.g. silenced completely, turned into an
308 exception, logged, etc.
309
310 Note that compare operators other than equal and unequal will still
311 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000312
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000313- Fix segfault when doing string formatting on subclasses of long.
314
315- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
316 with new-style classes.
317
318- Fix bug related to __len__ functions returning negative values with
319 classic classes.
320
321- Patch #1538606, Fix __index__() clipping. There were some problems
322 discovered with the API and how integers that didn't fit into Py_ssize_t
323 were handled. This patch attempts to provide enough alternatives
324 to effectively use __index__.
325
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000326- Bug #1536021: __hash__ may now return long int; the final hash
327 value is obtained by invoking hash on the long int.
328
Thomas Hellerab1049c2006-08-08 17:37:00 +0000329- Bug #1536786: buffer comparison could emit a RuntimeWarning.
330
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000331- Bug #1535165: fixed a segfault in input() and raw_input() when
332 sys.stdin is closed.
333
Thomas Heller74d36f02006-08-04 18:17:40 +0000334- On Windows, the PyErr_Warn function is now exported from
335 the Python dll again.
336
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000337- Bug #1191458: tracing over for loops now produces a line event
338 on each iteration. Fixing this problem required changing the .pyc
339 magic number. This means that .pyc files generated before 2.5c1
340 will be regenerated.
341
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000342- Bug #1333982: string/number constants were inappropriately stored
343 in the byte code and co_consts even if they were not used, ie
344 immediately popped off the stack.
345
Georg Brandle9462c72006-08-04 18:03:37 +0000346- Fixed a reference-counting problem in property().

349Library
350-------
351
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000352- Fix a bug in the ``compiler`` package that caused invalid code to be
353 generated for generator expressions.
354
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000355- The distutils version has been changed to 2.5.0. The change to
356 keep it programmatically in sync with the Python version running
357 the code (introduced in 2.5b3) has been reverted. It will continue
358 to be maintained manually as static string literal.
359
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000360- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000361 and this cannot be converted to the required C type, an exception is
362 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000363 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000364
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000365- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000366 an exception.
367
Tim Peterscbdd3502006-09-05 01:47:53 +0000368- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000369 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000370 workarounds for clocks with low resolution, to stop the code yielding
371 duplicate UUIDs.
372
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000373- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
374 before raising SystemExit, allowing IDLE to honor quit() and exit().
375
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000376- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
377
Georg Brandl7a1af772006-08-14 21:55:28 +0000378- Patch #1536071: trace.py should now find the full module name of a
379 file correctly even on Windows.
380
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000381- logging's atexit hook now runs even if the rest of the module has
382 already been cleaned up.
383
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000384- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000385
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000386- Bug #1531405, format_exception no longer raises an exception if
387 str(exception) raised an exception.
388
Neil Schemenauer06ded092006-08-04 16:20:30 +0000389- Fix a bug in the ``compiler`` package that caused invalid code to be
390 generated for nested functions.

401 raises the correct exceptions.
402
Thomas Heller1ce433e2006-08-14 16:20:04 +0000403- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
404 '-no-stack-protector' compiler flag for OpenBSD has been removed.
405
Thomas Heller86720042006-08-14 11:17:48 +0000406- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
407 uses the _as_parameter_ attribute when objects are passed to foreign
408 function calls. The ctypes version number was changed to 1.0.1.
409
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000410- Bug #1530559, struct.pack raises TypeError where it used to convert.
411 Passing float arguments to struct.pack when integers are expected
412 now triggers a DeprecationWarning.
413
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000414

436-----
437
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000438- Bug #1535502, build _hashlib on Windows, and use masm assembler
439 code in OpenSSL.
440
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000441- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Tim Peters4643c2f2006-08-10 22:45:34 +0000446C API
447-----
448
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000449- New API for Unicode rich comparisons: PyUnicode_RichCompare()
450
Tim Peters4643c2f2006-08-10 22:45:34 +0000451- Bug #1069160. Internal correctness changes were made to
452 ``PyThreadState_SetAsyncExc()``. A test case was added, and
453 the documentation was changed to state that the return value
454 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000457What's New in Python 2.5 beta 3?
458================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000459
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000460*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000461
462Core and builtins
463-----------------
464
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000465- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000466 returned a long (see PEP 353).
467
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000468- Bug #1515471: string.replace() accepts character buffers again.
469
Neal Norwitz07aadb12006-07-30 06:55:48 +0000470- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
471 This provides the proper warning for struct.pack().
472 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
473
Neal Norwitz0d62a062006-07-30 06:53:31 +0000474- Patch #1531113: Fix augmented assignment with yield expressions.
475 Also fix a SystemError when trying to assign to yield expressions.
476
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000477- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
478 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
479 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
480 excessive filesystem operations during imports.
481
Tim Petersbc24eee2006-07-27 01:14:53 +0000482- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
483 operations on signed longs that are formally undefined by C.
484 Unfortunately, at least one compiler now cares about that, so complicated
485 the code to make that compiler happy again.
486
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000487- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
488
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000489- Patch #1232023: Stop including current directory in search
490 path on Windows.
491
Neal Norwitze1fdb322006-07-21 05:32:28 +0000492- Fix some potential crashes found with failmalloc.
493
Neal Norwitze7563102006-07-17 01:00:16 +0000494- Fix warnings reported by Klocwork's static analysis tool.
495
Neal Norwitz84be93b2006-07-16 01:50:38 +0000496- Bug #1512814, Fix incorrect lineno's when code within a function
497 had more than 255 blank lines.
498
Georg Brandl9dceedb2006-07-12 15:31:17 +0000499- Patch #1521179: Python now accepts the standard options ``--help`` and
500 ``--version`` as well as ``/?`` on Windows.
501
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000502- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000503 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000504 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000505
Tim Peters112aad32006-07-19 00:03:19 +0000506- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000507 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000508 new ``sys._current_frames()`` returns a dictionary with one entry,
509 mapping the faux "thread id" 0 to the current frame.
510
Ronald Oussoren3075e162006-07-25 20:28:55 +0000511- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000512
Ronald Oussoren3075e162006-07-25 20:28:55 +0000513
Neal Norwitza1f10902006-07-12 07:28:29 +0000514Library
515-------
516
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000517- Correction of patch #1455898: In the mbcs decoder, set final=False
518 for stream decoder, but final=True for the decode function.
519
Georg Brandl07fec3a2006-08-01 18:49:24 +0000520- os.urandom no longer masks unrelated exceptions like SystemExit or
521 KeyboardInterrupt.
522
Tim Peters4643c2f2006-08-10 22:45:34 +0000523- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000524 shutil.copytree on Windows
525
Georg Brandle34ac7c2006-07-30 11:07:23 +0000526- Bug #1002398: The documentation for os.path.sameopenfile now correctly
527 refers to file descriptors, not file objects.
528
Tim Peterscbdd3502006-09-05 01:47:53 +0000529- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000530 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000531 #1513611, and probably others.
532
Georg Brandledd9b0d2006-07-29 09:33:26 +0000533- Bug #1441397: The compiler module now recognizes module and function
534 docstrings correctly as it did in Python 2.4.
535
Tim Peters6f681472006-07-27 23:44:37 +0000536- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
537 lost that tests are sorted by name before being run. This rarely
538 matters for well-written tests, but can create baffling symptoms if
539 side effects from one test to the next affect outcomes. ``DocTestFinder``
540 has been changed to sort the list of tests it returns.
541
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000542- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000543 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000544
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000545- Bug #978833: Really close underlying socket in _socketobject.close.
546
Georg Brandldb232dc2006-08-20 13:15:43 +0000547- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
548 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000549
Georg Brandlcf0c1722006-07-26 07:23:32 +0000550- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
551 to recursive calls and call it with the failing package name.
552
Martin v. Löwis0b483032006-07-25 09:53:12 +0000553- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
554
Georg Brandlc13c34c2006-07-24 14:09:56 +0000555- Patch #1515343: Fix printing of deprecated string exceptions with a
556 value in the traceback module.
557
Greg Ward48fae7a2006-07-23 16:05:51 +0000558- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
559
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000560- Patch #1524429: Use repr() instead of backticks in Tkinter again.
561
Brett Cannoncaebe222006-07-18 04:41:36 +0000562- Bug #1520914: Change time.strftime() to accept a zero for any position in its
563 argument tuple. For arguments where zero is illegal, the value is forced to
564 the minimum value that is correct. This is to support an undocumented but
565 common way people used to fill in inconsequential information in the time
566 tuple pre-2.4.
567
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000568- Patch #1220874: Update the binhex module for Mach-O.
569
Barry Warsawb110bad2006-07-21 14:51:07 +0000570- The email package has improved RFC 2231 support, specifically for
571 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
572 (name*0=<blah>) parameter continuations. This may change the types of
573 values returned from email.message.Message.get_param() and friends.
574 Specifically in some cases where non-encoded continuations were used,
575 get_param() used to return a 3-tuple of (None, None, string) whereas now it
576 will just return the string (since non-encoded continuations don't have
577 charset and language parts).
578
579 Also, whereas % values were decoded in all parameter continuations, they are
580 now only decoded in encoded parameter parts.
581
Ronald Oussoren3075e162006-07-25 20:28:55 +0000582- Bug #1517990: IDLE keybindings on MacOS X now work correctly
583
584- Bug #1517996: IDLE now longer shows the default Tk menu when a
585 path browser, class browser or debugger is the frontmost window on MacOS X
586
Barry Warsaw00decd72006-07-27 23:43:15 +0000587- Patch #1520294: Support for getset and member descriptors in types.py,
588 inspect.py, and pydoc.py. Specifically, this allows for querying the type
589 of an object against these built-in types and more importantly, for getting
590 their docstrings printed in the interactive interpreter's help() function.

595
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000596- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
597 a socket operation on a socket with a timeout, the exception will be
598 caught correctly. Previously, the exception was not caught.
599
Thomas Heller1393d6a2006-07-28 21:43:20 +0000600- Patch #1529514: The _ctypes extension is now compiled on more
601 openbsd target platforms.
602
Tim Peters9cab5932006-07-28 00:30:00 +0000603- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
604 a memory leak, affecting pickles and deep copies.
605
Tim Petersbc24eee2006-07-27 01:14:53 +0000606- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

608
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000609- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
610
Thomas Hellerce049a02006-07-14 17:51:14 +0000611- Patch #1521817: Index range checking on ctypes arrays containing
612 exactly one element enabled again. This allows iterating over these
613 arrays, without the need to check the array size before.

Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000615- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000616 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000617 /dev/null in certain cases; this is now fixed.
618
Thomas Heller47d7a062006-07-12 08:43:47 +0000619- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
620 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000621
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000622- Because of a misspelled preprocessor symbol, ctypes was always
623 compiled without thread support; this is now fixed.
624
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000625- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
626 methods now allow their database parameter to be None as the
627 sleepycat API allows.
628
Matt Flemingec926502006-07-28 11:27:27 +0000629- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
630 bluetooth API compared with Linux and FreeBSD.
631
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000632Tests
633-----
634
635- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
636 how long the test file should take to play. Now accepts taking 2.93 secs
637 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
638
Georg Brandl4793aa32006-07-28 18:31:39 +0000639- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
640 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
641 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000648Mac
649---
650
651- PythonLauncher now works correctly when the path to the script contains
652 characters that are treated specially by the shell (such as quotes).
653
654- Bug #1527397: PythonLauncher now launches scripts with the working directory
655 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000656 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000657 expect.

665Core and builtins
666-----------------
667
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000668- Bug #1441486: The literal representation of -(sys.maxint - 1)
669 again evaluates to a int object, not a long.
670
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000671- Bug #1501934: The scope of global variables that are locally assigned
672 using augmented assignment is now correctly determined.
673
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000674- Bug #927248: Recursive method-wrapper objects can now safely
675 be released.
676
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000677- Bug #1417699: Reject locale-specific decimal point in float()
678 and atof().
679
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000680- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
681 omit a default "error" argument for NULL pointer. This allows
682 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000683
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000684- Bug #1519018: 'as' is now validated properly in import statements.
685
Neal Norwitz28746ab2006-07-09 22:14:42 +0000686- On 64 bit systems, int literals that use less than 64 bits are
687 now ints rather than longs.
688
Neal Norwitzed657552006-07-10 00:04:44 +0000689- Bug #1512814, Fix incorrect lineno's when code at module scope
690 started after line 256.
691
Tim Peters32a83612006-07-10 21:08:24 +0000692- New function ``sys._current_frames()`` returns a dict mapping thread
693 id to topmost thread stack frame. This is for expert use, and is
694 especially useful for debugging application deadlocks. The functionality
695 was previously available in Fazal Majid's ``threadframe`` extension
696 module, but it wasn't possible to do this in a wholly threadsafe way from
697 an extension.

706
Tim Peters32a83612006-07-10 21:08:24 +0000707- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000708 environment variable to be set in order to the SDK environment
709 for finding the compiler, include files, etc.

714
Thomas Woutersadd19112006-07-05 11:03:49 +0000715- string.Template() now correctly handles tuple-values. Previously,
716 multi-value tuples would raise an exception and single-value tuples would
717 be treated as the value they contain, instead.
718
Martin v. Löwisede77f52006-07-03 13:01:35 +0000719- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
720 even if some data are received.
721
Martin v. Löwis45482392006-07-03 12:28:58 +0000722- Bug #1267547: Put proper recursive setup.py call into the

726 degrees and radians.
727
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000728- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000729 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000730
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000731- Bug #1514703: Only setup canvas window in turtle when the canvas
732 is created.
733
Martin v. Löwis7596e832006-07-01 15:33:37 +0000734- Bug #1513223: .close() of a _socketobj now releases the underlying
735 socket again, which then gets closed as it becomes unreferenced.
736
Fred Drake10497c82006-06-29 02:57:48 +0000737- Bug #1504333: Make sgmllib support angle brackets in quoted
738 attribute values.
739
740- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
741 sgmllib ('[' and ']' were not accepted).
742
Georg Brandl1be63af2006-06-28 20:23:25 +0000743- Fix a bug in the turtle module's end_fill function.
744
Brett Cannon53ab5b72006-06-22 16:49:14 +0000745- Bug #1510580: The 'warnings' module improperly required that a Warning
746 category be either a types.ClassType and a subclass of Warning. The proper
747 check is just that it is a subclass with Warning as the documentation states.
748
Georg Brandlad29e632006-06-21 17:45:17 +0000749- The compiler module now correctly compiles the new try-except-finally
750 statement (bug #1509132).
751
Neal Norwitz60373cd2006-06-22 06:30:50 +0000752- The wsgiref package is now installed properly on Unix.
753
Vinay Sajip28e57612006-07-01 10:45:20 +0000754- A bug was fixed in logging.config.fileConfig() which caused a crash on
755 shutdown when fileConfig() was called multiple times.
756
Gerhard Häring762fbd32006-07-02 17:48:30 +0000757- The sqlite3 module did cut off data from the SQLite database at the first
758 null character before sending it to a custom converter. This has been fixed
759 now.
760
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000761Extension Modules
762-----------------
763
Tim Peters112aad32006-07-19 00:03:19 +0000764- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
765 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
766 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000767
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000768- Assigning None to pointer type fields in ctypes structures possible
769 overwrote the wrong fields, this is fixed now.
770
771- Fixed a segfault in _ctypes when ctypes.wintypes were imported
772 on non-Windows platforms.
773
774- Bug #1518190: The ctypes.c_void_p constructor now accepts any
775 integer or long, without range checking.
776
777- Patch #1517790: It is now possible to use custom objects in the ctypes
778 foreign function argtypes sequence as long as they provide a from_param
779 method, no longer is it required that the object is a ctypes type.
780
781- The '_ctypes' extension module now works when Python is configured
782 with the --without-threads option.
783
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000784- Bug #1513646: os.access on Windows now correctly determines write
785 access, again.
786
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000787- Bug #1512695: cPickle.loads could crash if it was interrupted with
788 a KeyboardInterrupt.
789
Neal Norwitza12aa882006-07-06 06:45:08 +0000790- Bug #1296433: parsing XML with a non-default encoding and
791 a CharacterDataHandler could crash the interpreter in pyexpat.

794
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000795Build
796-----
797
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000798- Automate Windows build process for the Win64 SSL module.
799
Tim Peters32a83612006-07-10 21:08:24 +0000800- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000801 Previously, the slight difference could cause compilation errors of the
802 'zlib' module on systems with more than one version of zlib.
803
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000804- The MSI compileall step was fixed to also support a TARGETDIR
805 with spaces in it.
806
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000807- Bug #1517388: sqlite3.dll is now installed on Windows independent
808 of Tcl/Tk.
809
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000810- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000811 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +0000813Tests
814-----
815
816- Call os.waitpid() at the end of tests that spawn child processes in order
817 to minimize resources (zombies).
818
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000819Documentation
820-------------
821
Nick Coghlan2d792252006-07-06 13:47:18 +0000822- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
823 documentation for the warnings module.
824
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000825- Patch #1509163: MS Toolkit Compiler no longer available.
826
Neal Norwitz56640df2006-07-10 02:36:41 +0000827- Patch #1504046: Add documentation for xml.etree.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000834
835Core and builtins
836-----------------
837
Georg Brandla56b9152006-06-19 06:35:54 +0000838- Patch #1507676: Error messages returned by invalid abstract object operations
839 (such as iterating over an integer) have been improved and now include the
840 type of the offending object to help with debugging.
841
Brett Cannonea3912b2006-06-13 21:46:41 +0000842- Bug #992017: A classic class that defined a __coerce__() method that returned
843 its arguments swapped would infinitely recurse and segfault the interpreter.
844
Neal Norwitz909eb122006-06-12 02:13:21 +0000845- Fix the socket tests so they can be run concurrently.
846
Neal Norwitzb9845e72006-06-12 02:11:18 +0000847- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000848 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000849
Brett Cannon22565aa2006-06-09 22:31:23 +0000850- Bug #532646: object.__call__() will continue looking for the __call__
851 attribute on objects until one without one is found. This leads to recursion
852 when you take a class and set its __call__ attribute to an instance of the
853 class. Originally fixed for classic classes, but this fix is for new-style.
854 Removes the infinite_rec_3 crasher.
855
Georg Brandl24250812006-06-09 18:45:48 +0000856- The string and unicode methods startswith() and endswith() now accept
857 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
858
Brett Cannonde3b0522006-06-08 17:00:45 +0000859- Buffer objects, at the C level, never used the char buffer
860 implementation even when the char buffer for the wrapped object was
861 explicitly requested (originally returned the read or write buffer).
862 Now a TypeError is raised if the char buffer is not present but is
863 requested.
864
Georg Brandlddbaa662006-06-04 21:56:52 +0000865- Patch #1346214: Statements like "if 0: suite" are now again optimized
866 away like they were in Python 2.4.
867
Georg Brandlb7c8f542006-05-27 12:30:25 +0000868- Builtin exceptions are now full-blown new-style classes instead of
869 instances pretending to be classes, which speeds up exception handling
870 by about 80% in comparison to 2.5a2.
871
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000872- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
873 Unicode 4.1.
874
Georg Brandlf4ef1162006-05-26 18:03:31 +0000875- Patch #921466: sys.path_importer_cache is now used to cache valid and
876 invalid file paths for the built-in import machinery which leads to
877 fewer open calls on startup.
878
Tim Peters696cf432006-05-24 21:10:40 +0000879- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
880 of-2 bases. The largest speedup is for inputs with about 1000 decimal
881 digits. Conversion from non-power-of-2 bases remains quadratic-time in
882 the number of input digits (it was and remains linear-time for bases
883 2, 4, 8, 16 and 32).
884
Tim Petersb713ec22006-05-23 18:45:30 +0000885- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
886 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
887 an integer close to ``sys.maxint``. This was repaired by patch
888 #1335972, which also gives a nice speedup.
889
Richard Jonescebbefc2006-05-23 18:28:17 +0000890- Patch #1337051: reduced size of frame objects.
891
892- PyErr_NewException now accepts a tuple of base classes as its
893 "base" parameter.
894
Richard Jones7c88dcc2006-05-23 10:37:38 +0000895- Patch #876206: function call speedup by retaining allocated frame
896 objects.
897
Georg Brandl7b90e162006-05-18 07:01:27 +0000898- Bug #1462152: file() now checks more thoroughly for invalid mode
899 strings and removes a possible "U" before passing the mode to the
900 C library function.
901
Neal Norwitz1004a532006-05-15 07:17:23 +0000902- Patch #1488312, Fix memory alignment problem on SPARC in unicode
903
Neal Norwitz373f0a72006-05-15 07:04:36 +0000904- Bug #1487966: Fix SystemError with conditional expression in assignment
905
Martin v. Löwis879768d2006-05-11 13:28:43 +0000906- WindowsError now has two error code attributes: errno, which carries
907 the error values from errno.h, and winerror, which carries the error
908 values from winerror.h. Previous versions put the winerror.h values
909 (from GetLastError()) into the errno attribute.
910
Martin v. Löwis77736712006-05-04 05:51:03 +0000911- Patch #1475845: Raise IndentationError for unexpected indent.
912
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000913- Patch #1479181: split open() and file() from being aliases for each other.
914
Tim Peters44bd9862006-06-01 13:49:23 +0000915- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
916 methods were always silently ignored by dictionaries when comparing keys.
917 They are now passed through (except when using the C API function
918 ``PyDict_GetItem()``, whose semantics did not change).
919
920- Bug #1456209: In some obscure cases it was possible for a class with a
921 custom ``__eq__()`` method to confuse dict internals when class instances
922 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
923 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000925Extension Modules
926-----------------
927
Trent Mick960a3f82006-06-28 20:30:41 +0000928- Bug #1295808: expat symbols should be namespaced in pyexpat
929
930- Patch #1462338: Upgrade pyexpat to expat 2.0.0
931
Brett Cannon6ee7d012006-06-08 16:23:04 +0000932- Change binascii.hexlify to accept a read-only buffer instead of only a char
933 buffer and actually follow its documentation.
934
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000935- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
936
Nick Coghlanc649ec52006-05-29 12:43:05 +0000937- Patch #1478788 (modified version): The functional extension module has
938 been renamed to _functools and a functools Python wrapper module added.
939 This provides a home for additional function related utilities that are
940 not specifically about functional programming. See PEP 309.
941
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000942- Patch #1493701: performance enhancements for struct module.
943
Georg Brandl378d5922006-05-17 14:26:50 +0000944- Patch #1490224: time.altzone is now set correctly on Cygwin.
945
Georg Brandl8d3342b2006-05-16 07:38:27 +0000946- Patch #1435422: zlib's compress and decompress objects now have a
947 copy() method.
948
Andrew MacIntyre92913322006-06-13 15:04:24 +0000949- Patch #1454481: thread stack size is now tunable at runtime for thread
950 enabled builds on Windows and systems with Posix threads support.
951
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000952- On Win32, os.listdir now supports arbitrarily-long Unicode path names
953 (up to the system limit of 32K characters).
954
955- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
956 As a result, these functions now raise WindowsError instead of OSError.
957
Tim Peters7a822da2006-05-25 21:50:17 +0000958- ``time.clock()`` on Win64 should use the high-performance Windows
959 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
960 Windows platforms).
961
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000962- Calling Tk_Init twice is refused if the first call failed as that
963 may deadlock.
964
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000965- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
966 accept it without potentially using an uninitialized pointer.
967
968- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
969 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
970 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000971
Gregory P. Smith372b5832006-06-05 18:48:21 +0000972- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000973 [pybsddb project SF patch number 1466734]
974
Gregory P. Smith372b5832006-06-05 18:48:21 +0000975- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
976 parameter is supplied. [SF pybsddb bug #1477863]
977
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000978- bsddb: the __len__ method of a DB object has been fixed to return correct
979 results. It could previously incorrectly return 0 in some cases.
980 Fixes SF bug 1493322 (pybsddb bug 1184012).
981
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000982- bsddb: the bsddb.dbtables Modify method now raises the proper error and
983 aborts the db transaction safely when a modifier callback fails.
984 Fixes SF python patch/bug #1408584.
985
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000986- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000987 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000988 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
989 database calls that would previously deadlock. [SF python bug #775414]
990
Vinay Sajip28e57612006-07-01 10:45:20 +0000991- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000992
Walter Dörwald4994d952006-06-19 08:07:50 +0000993- Patch #1506645: add Python wrappers for the curses functions
994 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000995

998
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000999- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1000 functions.
1001
Martin v. Löwis3798da02006-06-17 18:44:27 +00001002- Patch #812986: Update turtle output even if not tracing.
1003
Vinay Sajip28e57612006-07-01 10:45:20 +00001004- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001005 Tkinter.BaseWidget.
1006
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001007- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1008
Martin v. Löwis337487e2006-06-17 09:15:14 +00001009- Patch #763580: Add name and value arguments to Tkinter variable
1010 classes.
1011
Georg Brandl83cc0d02006-06-14 08:50:03 +00001012- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1013 mime.types file for determining MIME types.
1014
Georg Brandl2605ca82006-06-14 06:08:31 +00001015- Bug #1339007: Shelf objects now don't raise an exception in their
1016 __del__ method when initialization failed.
1017
Martin v. Löwisd8251432006-06-14 05:21:04 +00001018- Patch #1455898: The MBCS codec now supports the incremental mode for
1019 double-byte encodings.
1020
Tim Peters43898b42006-06-14 04:09:25 +00001021- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1022 guarantee that adjacent triples in the return list always describe
1023 non-adjacent blocks. Previously, a pair of matching blocks could end
1024 up being described by multiple adjacent triples that formed a partition
1025 of the matching pair.
1026
Greg Ward0e0c9f42006-06-11 16:24:11 +00001027- Bug #1498146: fix optparse to handle Unicode strings in option help,
1028 description, and epilog.
1029
Greg Wardd1c797e2006-06-11 14:42:41 +00001030- Bug #1366250: minor optparse documentation error.
1031
Greg Ward7f547402006-06-11 00:40:49 +00001032- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1033 clarify docs.
1034
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001035- The wsgiref package has been added to the standard library.
1036
Nick Coghlan676725d2006-06-08 13:54:49 +00001037- The functions update_wrapper() and wraps() have been added to the functools
1038 module. These make it easier to copy relevant metadata from the original
1039 function when writing wrapper functions.
1040
Tim Petersd6a9eef2006-06-05 01:48:21 +00001041- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1042 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001043
Martin v. Löwis3f767792006-06-04 19:36:28 +00001044- Patch #1359618: Speed up charmap encoder by using a trie structure
1045 for lookup.
1046
Tim Petersd609b1a2006-06-02 23:22:51 +00001047- The functions in the ``pprint`` module now sort dictionaries by key
1048 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1049 if and only if its display required more than one line, although that
1050 wasn't documented. The new behavior increases predictability; e.g.,
1051 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1052
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001053- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1054 (thanks for J. J. Lee).
1055
Georg Brandl2b330372006-05-28 20:23:12 +00001056- Patch #1496206: improve urllib2 handling of passwords with respect to
1057 default HTTP and HTTPS ports.
1058
George Yoshidaf3c65de2006-05-28 16:39:09 +00001059- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1060
Bob Ippolito7298f272006-05-23 18:43:47 +00001061- Patch #1281707: speed up gzip.readline.
1062
Georg Brandlb89316f2006-05-17 15:51:16 +00001063- Patch #1180296: Two new functions were added to the locale module:
1064 format_string() to get the effect of "format % items" but locale-aware,
1065 and currency() to format a monetary number with currency sign.
1066
Georg Brandle3a25832006-05-17 14:56:04 +00001067- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1068 and several features added, such as speed and geometry control.
1069
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001070- Patch #1488881: add support for external file objects in bz2 compressed
1071 tarfiles.
1072
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001073- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1074 stdout arguments, making it possible to redirect input and output
1075 for remote debugging.
1076
1077- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1078 a couple of issues, notably handling of long file names using the
1079 GNU LONGNAME extension.
1080
1081- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1082 new flag when ``name`` is already the name of an option flag.
1083
1084- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1085 package.
1086
1087- Patch #1472854: make the rlcompleter.Completer class usable on non-
1088 UNIX platforms.
1089
1090- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1091
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001092- Bug #1472827: correctly escape newlines and tabs in attribute values in
1093 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001123What's New in Python 2.5 alpha 2?

1125
1126*Release date: 27-APR-2006*
1127
1128Core and builtins
1129-----------------
1130
Thomas Heller1b046642006-04-18 18:51:06 +00001131- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1132 by converting these apis from macros into exported functions again:
1133
1134 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1135 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1136 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1137 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1138 PyRun_String Py_CompileString
1139
Martin v. Löwis45294a92006-04-18 06:24:08 +00001140- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1141
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001142- All uses of PyStructSequence_InitType have been changed to initialize
1143 the type objects only once, even if the interpreter is initialized
1144 multiple times.
1145
Neal Norwitz61546162006-04-14 05:20:28 +00001146- Bug #1454485, array.array('u') could crash the interpreter. This was
1147 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1148 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1149
1150- Py_UNICODE is unsigned. It was always documented as unsigned, but
1151 due to a bug had a signed value in previous versions.
1152
Tim Peters3a5e8b12006-04-11 01:44:07 +00001153- Patch #837242: ``id()`` of any Python object always gives a positive
1154 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1155 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001156 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001157 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001158
Tim Peters3a5e8b12006-04-11 01:44:07 +00001159 def __hash__(self):
1160 return id(self) # WRONG
1161
1162 because a hash result must be a (short) Python int but it was always
1163 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001164 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001165 was always usable as a hash value before this patch. That's no longer
1166 necessarily so.
1167
1168- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001169 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001170 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001171 #1454844)
1172
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001173- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1174 involving generators that have paused outside of any ``try`` or ``with``
1175 blocks. (In 2.5a1, a paused generator that was part of a reference
1176 cycle could not be garbage collected, regardless of whether it was
1177 paused in a ``try`` or ``with`` block.)

1186 fails with an error condition.
1187
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001188- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1189
1190- Bug #1117761: bsddb.*open() no longer raises an exception when using
1191 the cachesize parameter.
1192
1193- Bug #1149413: bsddb.*open() no longer raises an exception when using
1194 a temporary db (file=None) with the 'n' flag to truncate on open.
1195
1196- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1197 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001198
Armin Rigoa9017c32006-04-19 11:50:27 +00001199- Patch #1062014: AF_UNIX sockets under Linux have a special

1203-------
1204
Peter Astrand7d1d4362006-07-14 14:04:45 +00001205- Bug #1223937: subprocess.CalledProcessError reports the exit status
1206 of the process using the returncode attribute, instead of
1207 abusing errno.
1208
Tim Peters711bf302006-04-25 03:31:36 +00001209- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1210 a doctest to be skipped (the code is not run, and the expected output
1211 or exception is ignored).
1212
Nick Coghlanda2268f2006-04-24 04:37:15 +00001213- Fixed contextlib.nested to cope with exceptions being raised and
1214 caught inside exit handlers.
1215
Greg Wardab05edc2006-04-23 03:47:58 +00001216- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1217 hex, octal, or binary; add ``append_const`` action; keep going if
1218 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1219 added ``epilog`` for better help generation).
1220
Tim Peters21fbd572006-04-21 21:18:10 +00001221- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1222 called from a thread spawned as a side effect of importing a module.
1223
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001224- The pydoc module now supports documenting packages contained in
1225 .zip or .egg files.
1226
1227- The pkgutil module now has several new utility functions, such
1228 as ``walk_packages()`` to support working with packages that are either
1229 in the filesystem or zip files.
1230
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001231- The mailbox module can now modify and delete messages from
1232 mailboxes, in addition to simply reading them. Thanks to Gregory

Skip Montanaro262fb922006-04-21 02:31:07 +00001259- The pstats.Stats class accepts an optional stream keyword argument to
1260 direct output to an alternate file-like object.
1261
Anthony Baxter51bcb682006-04-05 14:51:42 +00001262Build
1263-----
1264
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001265- The Makefile now has a reindent target, which runs reindent.py on
1266 the library.
1267
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001268- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001271
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001272- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1273 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001274 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001275 CXX from --with-cxx-main, see description in README.
1276
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001277- Patch #1429775: Link extension modules with the shared libpython.
1278
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001279- Fixed a libffi build problem on MIPS systems.
1280
Tim Peters8931ff12006-05-13 23:28:20 +00001281- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1282 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1283 and "%zu" for unsigned integers of type ``size_t``.
1284
Anthony Baxter51bcb682006-04-05 14:51:42 +00001285Tests
1286-----
1287
Nick Coghlanda2268f2006-04-24 04:37:15 +00001288- test_contextlib now checks contextlib.nested can cope with exceptions
1289 being raised and caught inside exit handlers.
1290
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001291- test_cmd_line now checks operation of the -m and -c command switches
1292
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001293- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1294 it separately and by hand. It also wasn't cleaning up its changes to
1295 the current Decimal context.
1296
Thomas Woutersabd08882006-04-26 15:53:30 +00001297- regrtest.py now has a -M option to run tests that test the new limits of
1298 containers, on 64-bit architectures. Running these tests is only sensible
1299 on 64-bit machines with more than two gigabytes of memory. The argument
1300 passed is the maximum amount of memory for the tests to use.

1309-------------
1310
Tim Petersb06d28c2006-05-12 01:57:59 +00001311- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1312
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001313- PEP 343: Added Context Types section to the library reference
1314 and attempted to bring other PEP 343 related documentation into
1315 line with the implementation and/or python-dev discussions.
1316
Tim Peters8dc73d22006-04-24 02:03:16 +00001317- Bug #1337990: clarified that ``doctest`` does not support examples
1318 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001321What's New in Python 2.5 alpha 1?
1322=================================
1323
Anthony Baxterebed3f62006-04-03 15:03:44 +00001324*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001325
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001326Core and builtins
1327-----------------
1328
Nick Coghlan43832302006-04-23 17:04:07 +00001329- PEP 338: -m command line switch now delegates to runpy.run_module
1330 allowing it to support modules in packages and zipfiles
1331
Martin v. Löwisc661b882006-04-20 04:54:23 +00001332- On Windows, .DLL is not an accepted file name extension for
1333 extension modules anymore; extensions are only found if they
1334 end in .PYD.
1335
Martin v. Löwisea62d252006-04-03 10:56:49 +00001336- Bug #1421664: sys.stderr.encoding is now set to the same value as
1337 sys.stdout.encoding.
1338
Neal Norwitz92e212f2006-04-03 04:48:37 +00001339- __import__ accepts keyword arguments.
1340
Georg Brandlccadf842006-03-31 18:54:53 +00001341- Patch #1460496: round() now accepts keyword arguments.
1342
Anthony Baxter262c00a2006-03-30 10:53:17 +00001343- Fixed bug #1459029 - unicode reprs were double-escaped.
1344
Hye-Shik Changd478f342006-03-23 12:32:36 +00001345- Patch #1396919: The system scope threads are reenabled on FreeBSD
1346 5.4 and later versions.
1347
Neal Norwitze98ccf62006-03-23 05:39:47 +00001348- Bug #1115379: Compiling a Unicode string with an encoding declaration
1349 now gives a SyntaxError.
1350
Georg Brandlabd1ff82006-03-18 07:59:59 +00001351- Previously, Python code had no easy way to access the contents of a
1352 cell object. Now, a ``cell_contents`` attribute has been added
1353 (closes patch #1170323).
1354
Tim Peterscf79aac2006-03-16 01:14:46 +00001355- Patch #1123430: Python's small-object allocator now returns an arena to
1356 the system ``free()`` when all memory within an arena becomes unused
1357 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1358 freed. Some applications will see a drop in virtual memory size now,
1359 especially long-running applications that, from time to time, temporarily
1360 use a large number of small objects. Note that when Python returns an
1361 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001362 platform C library will in turn return that memory to the operating system.
1363 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001364 appears to be effective at least on Microsoft C and gcc-based systems.
1365 Thanks to Evan Jones for hard work and patience.
1366
Georg Brandl533ff6f2006-03-08 18:09:27 +00001367- Patch #1434038: property() now uses the getter's docstring if there is
1368 no "doc" argument given. This makes it possible to legitimately use
1369 property() as a decorator to produce a read-only property.
1370
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001371- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1372 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1373 of requiring an int or long in slicing and a few other contexts, enabling
1374 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1375
Neal Norwitz995acdf2006-03-07 05:01:00 +00001376- Fixed various bugs reported by Coverity's Prevent tool.
1377
Brett Cannonbf364092006-03-01 04:25:17 +00001378- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1379 new exception base class, BaseException, which has a new message attribute.
1380 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1381 Raising a string exception now raises a DeprecationWarning.
1382
Thomas Woutersfb609f42006-02-28 16:37:25 +00001383- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1384 explicitly relative, using 'from .module import name' to mean 'from the same
1385 package as this module is in. Imports without dots still default to the
1386 old relative-then-absolute, unless 'from __future__ import
1387 absolute_import' is used.
1388
Brett Cannona7446e32006-02-27 23:39:10 +00001389- Properly check if 'warnings' raises an exception (usually when a filter set
1390 to "error" is triggered) when raising a warning for raising string
1391 exceptions.
1392
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001393- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001394 The name was removed from Include/code.h.
1395
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001396- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001397
Guido van Rossum1968ad32006-02-25 22:38:04 +00001398- Patch 1433928:
1399 - The copy module now "copies" function objects (as atomic objects).
1400 - dict.__getitem__ now looks for a __missing__ hook before raising
1401 KeyError.
1402
Tim Peters84ef21c2006-02-28 20:39:06 +00001403- PEP 343: with statement implemented. Needs ``from __future__ import
1404 with_statement``. Use of 'with' as a variable will generate a warning.
1405 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001406 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001407 The following objects have __context__ methods:
1408 - The built-in file type.
1409 - The thread.LockType type.
1410 - The following types defined by the threading module:
1411 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1412 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001413
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001414- Fix the encodings package codec search function to only search
1415 inside its own package. Fixes problem reported in patch #1433198.
1416
1417 Note: Codec packages should implement and register their own
1418 codec search function. PEP 100 has the details.
1419
Tim Peters9ea89d22006-06-04 03:26:02 +00001420- PEP 353: Using ``Py_ssize_t`` as the index type.
1421
1422- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1423 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1424 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1425 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1426 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001427
Neal Norwitzfc76d632006-01-10 06:03:13 +00001428- Patch #1400181, fix unicode string formatting to not use the locale.
1429 This is how string objects work. u'%f' could use , instead of .
1430 for the decimal point. Now both strings and unicode always use periods.
1431
Neal Norwitz671b9e32006-01-09 07:07:12 +00001432- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1433 configure would break checking curses.h.
1434
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001435- Bug #959576: The pwd module is now builtin. This allows Python to be
1436 built on UNIX platforms without $HOME set.
1437
Neal Norwitzc10978f2005-12-19 06:07:16 +00001438- Bug #1072182, fix some potential problems if characters are signed.
1439
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001440- Bug #889500, fix line number on SyntaxWarning for global declarations.
1441
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001442- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1443
Neal Norwitze7214a12005-12-18 05:03:17 +00001444- Support for converting hex strings to floats no longer works.
1445 This was not portable. float('0x3') now raises a ValueError.
1446
Barry Warsaw2a38a862005-12-18 01:27:35 +00001447- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001448 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001449 is now displayed in interactive prompt banner.
1450
Georg Brandlfa166682005-12-17 21:45:17 +00001451- Implementation of PEP 341 - Unification of try/except and try/finally.
1452 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001453 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001454
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001455- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1456 now encodes backslash correctly.
1457
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001458- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1459
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001460- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001461 and long longs.
1462
Neal Norwitz67715f02005-11-09 06:59:35 +00001463- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001464 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001465 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001466
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001467- Replaced most Unicode charmap codecs with new ones using the
1468 new Unicode translate string feature in the builtin charmap
1469 codec; the codecs were created from the mapping tables available
1470 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1471 encodings now include a mapping for the Apple logo)
1472
Tim Peterse3547fd2005-12-16 23:13:57 +00001473- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001474
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001475- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001476
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001477- A new AST parser implementation was completed. The abstract
1478 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001479 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001480
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001481- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001482 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1483
Neal Norwitz708e51a2005-10-03 04:48:15 +00001484- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1485
Neal Norwitz11bd1192005-10-03 00:54:56 +00001486- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1487 Provide a warning when a directory is passed on the command line.
1488
Neal Norwitz40d37812005-10-02 01:48:49 +00001489- Fix segfault with invalid coding.
1490
1491- SF bug #772896: unknown encoding results in MemoryError.
1492
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001493- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001494 supported a __len__() method which evaluated to False when the iterator
1495 was empty.
1496
Guido van Rossum630db602005-09-20 18:49:54 +00001497- On 64-bit platforms, when __len__() returns a value that cannot be
1498 represented as a C int, raise OverflowError.
1499
Skip Montanarof8948ca2005-09-19 03:54:46 +00001500- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001501 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001502
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001503- SF bug #893549: parsing keyword arguments was broken with a few format
1504 codes.
1505
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001506- Changes donated by Elemental Security to make it work on AIX 5.3
1507 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1508 bug #105470: test_pwd fails on 64bit system (Opteron).
1509
Guido van Rossum539c6622005-09-14 17:49:54 +00001510- Changes donated by Elemental Security to make it work on HP-UX 11 on
1511 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1512
Georg Brandl4550b8d2005-08-26 06:43:52 +00001513- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001514 (fixes bug #1119418).
1515
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001516- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1517
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001518- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1519 exceptions that cause a function to exit.
1520
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001521- The implementation of set() and frozenset() was revised to use its
1522 own internal data structure. Memory consumption is reduced by 1/3
1523 and there are modest speed-ups as well. The API is unchanged.
1524
Tim Petersde7990b2005-07-17 23:45:23 +00001525- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1526
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001527- SF bug #1229429: PyObject_CallMethod failed to decrement some
1528 reference counts in some error exit cases.
1529
Tim Petersecc6e6a2005-07-10 22:30:55 +00001530- SF bug #1185883: Python's small-object memory allocator took over
1531 a block managed by the platform C library whenever a realloc specified
1532 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001533 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001534 portable way to copy data from the C-managed block into Python's
1535 small-object space without risking a memory fault. Python's small-object
1536 realloc now leaves such blocks under the control of the platform C
1537 realloc.
1538
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001539- SF bug #1232517: An overflow error was not detected properly when
1540 attempting to convert a large float to an int in os.utime().
1541
Raymond Hettinger3296e692005-06-29 23:29:56 +00001542- SF bug #1224347: hex longs now print with lowercase letters just
1543 like their int counterparts.
1544
Michael W. Hudson188d4362005-06-20 16:52:57 +00001545- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1546 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1547 interpreter states; back out that fix and do a better job (see
1548 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1549 for a longer write-up of the problem).
1550
Michael W. Hudsondf888462005-06-03 14:41:55 +00001551- SF patch #1180995: marshal now uses a binary format by default when
1552 serializing floats.
1553
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001554- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1555 the routines that promise to produce IEEE 754 binary representations
1556 of floats now simply copy bytes around.
1557
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001558- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1559 278.
1560
Brett Cannonc3647ac2005-04-26 03:45:26 +00001561- patch #1109424: int, long, float, complex, and unicode now check for the
1562 proper magic slot for type conversions when subclassed. Previously the
1563 magic slot was ignored during conversion. Semantics now match the way
1564 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001565 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001566 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001567 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001568
Barry Warsawc8d907c2005-04-19 23:43:40 +00001569- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1570 NULL, now raise an AttributeError when attempting to set or delete the
1571 attribute. Previously a TypeError was raised, but this was inconsistent
1572 with the equivalent pure-Python implementation.
1573
Michael W. Hudson774479c2005-04-18 08:46:17 +00001574- It is now safe to call PyGILState_Release() before
1575 PyEval_InitThreads() (note that if there is reason to believe there
1576 are multiple threads around you still must call PyEval_InitThreads()
1577 before using the Python API; this fix is for extension modules that
1578 have no way of knowing if Python is multi-threaded yet).
1579
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001580- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1581 disabled caused a crash.
1582
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001583- Bug #1165306: instancemethod_new allowed the creation of a method
1584 with im_class == im_self == NULL, which caused a crash when called.
1585
Tim Petersecc6e6a2005-07-10 22:30:55 +00001586- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001587 fixes the crash seen in bug #1165761
1588
Raymond Hettinger96229b12005-03-11 06:49:40 +00001589- Added two new builtins, any() and all().
1590
Brett Cannon409d8f22005-03-05 06:47:57 +00001591- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001592 (e.g., ``class C(): pass`` is no longer a syntax error).
1593 Patch #1176012 added support to the 'parser' module and 'compiler' package
1594 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001595
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001596- Patch #1115086: Support PY_LONGLONG in structmember.
1597
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001598- Bug #1155938: new style classes did not check that __init__() was
1599 returning None.
1600
Tim Petersecc6e6a2005-07-10 22:30:55 +00001601- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001602 ('\') with a specific error message.
1603
Martin v. Löwisff232d72005-03-03 09:24:38 +00001604- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1605
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001606- Bug #1124295: the __name__ attribute of file objects was
1607 inadvertently made inaccessible in restricted mode.
1608
Tim Petersecc6e6a2005-07-10 22:30:55 +00001609- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001610 an ferror() call.
1611
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001612- min() and max() now support key= arguments with the same meaning as in
1613 list.sort().
1614
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001615- The peephole optimizer now performs simple constant folding in expressions:
1616 (2+3) --> (5).
1617
Raymond Hettingera422c342005-01-11 03:03:27 +00001618- set and frozenset objects can now be marshalled. SF #1098985.
1619
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001620- Bug #1077106: Poor argument checking could cause memory corruption
1621 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001622
Jeremy Hyltonab630502005-02-04 18:44:06 +00001623- The parser did not complain about future statements in illegal
1624 positions. It once again reports a syntax error if a future
1625 statement occurs after anything other than a doc string.
1626
Neil Schemenauercf52c072005-08-12 17:34:58 +00001627- Change the %s format specifier for str objects so that it returns a
1628 unicode instance if the argument is not an instance of basestring and
1629 calling __str__ on the argument returns a unicode instance.
1630
Tim Petersf4e69282006-02-27 17:15:31 +00001631- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1632 current thread state when the auto-GIL-state machinery knows about
1633 it (since the thread state is being deleted, continuing to remember it
1634 can't help, but can hurt if another thread happens to get created with
1635 the same thread id).
1636
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001637Extension Modules

1654
1655- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1656
1657- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001658 is deprecated. The undocumented re.engine variable no longer exists.
1659

1661 SS2 (single-shift 2) escape sequences correctly.
1662
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001663- The unicodedata module was updated to the 4.1 version of the Unicode
1664 database. The 3.2 version is still available as unicodedata.db_3_2_0
1665 for applications that require this specific version (such as IDNA).
1666
Neal Norwitzb62c4332006-03-04 18:35:47 +00001667- The timing module is no longer built by default. It was deprecated
1668 in PEP 4 in Python 2.0 or earlier.
1669
Guido van Rossum1968ad32006-02-25 22:38:04 +00001670- Patch 1433928: Added a new type, defaultdict, to the collections module.
1671 This uses the new __missing__ hook behavior added to dict (see above).
1672
Georg Brandldbd83392006-02-20 09:42:33 +00001673- Bug #854823: socketmodule now builds on Sun platforms even when
1674 INET_ADDRSTRLEN is not defined.
1675
Georg Brandlf4f44152006-02-18 22:29:33 +00001676- Patch #1393157: os.startfile() now has an optional argument to specify
1677 a "command verb" to invoke on the file.
1678
Neal Norwitz082b2df2006-02-07 07:04:46 +00001679- Bug #876637, prevent stack corruption when socket descriptor

1681
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001682- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1683 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1684 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

1687 than the system default domain.
1688
Martin v. Löwis14694662006-02-03 12:54:16 +00001689- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1690 are reported, the limit on path name lengths is removed, and stat reports
1691 WindowsError now (instead of OSError).
1692
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001693- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

1768 the request code argument, which results in more C-like behaviour
1769 for large or negative values.
1770
Tim Petersecc6e6a2005-07-10 22:30:55 +00001771- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

1813
Raymond Hettingerb2594052004-12-05 09:25:51 +00001814- itertools.islice() now accepts None for the start and step arguments.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001827- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1828 been renamed to have only a single underscore prefix. This was done to
1829 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001830
Nick Coghlan43832302006-04-23 17:04:07 +00001831- PEP 338: new module runpy defines a run_module function to support
1832 executing modules which provide access to source code or a code object
1833 via the PEP 302 import mechanisms.
1834
Anthony Baxter93f5b932006-04-03 08:05:07 +00001835- The email module's parsedate_tz function now sets the daylight savings

1843 in attribute values.
1844
Anthony Baxterc51ee692006-04-01 00:57:31 +00001845- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001846 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001847 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001848 module will not be built.
1849
Tim Petersc17976e2006-04-01 00:26:53 +00001850- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1851 aren't officially supported here, and trying to use them will probably
1852 raise an exception some day. But dicts have been allowed, and "mostly
1853 worked", so support for them won't go away without warning.
1854
Georg Brandl338ef7d2006-03-31 18:42:16 +00001855- Bug #1445068: getpass.getpass() can now be given an explicit stream
1856 argument to specify where to write the prompt.
1857
Georg Brandl22ec80b2006-03-31 18:25:44 +00001858- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1867 to make it easier to monitor when daemon threads have completed
1868 processing all enqueued tasks. Patch #1455676.
1869

1873
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001874- email 4.0 package now integrated. This is largely the same as the email 3.0
1875 package that was included in Python 2.3, except that PEP 8 module names are
1876 now used (e.g. mail.message instead of email.Message). The MIME classes
1877 have been moved to a subpackage (e.g. email.mime.text instead of
1878 email.MIMEText). The old names are still supported for now. Several
1879 deprecated Message methods have been removed and lots of bugs have been
1880 fixed. More details can be found in the email package documentation.
1881
Walter Dörwald40108c92006-03-27 08:15:44 +00001882- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1883 (a subclass of tuple) that provides incremental decoders and encoders
1884 (a way to use stateful codecs without the stream API). Python functions
1885 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1886 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1887 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001888
Walter Dörwald067db482006-03-15 22:17:27 +00001889- Patch #1359365: Calling next() on a closed StringIO.String object raises
1890 a ValueError instead of a StopIteration now (like file and cString.String do).
1891 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1892 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001893
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001894- A regrtest option -w was added to re-run failed tests in verbose mode.

Tim Peterse3547fd2005-12-16 23:13:57 +00001966 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1967 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1968 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1969 Ronald L. Rivest offered this advice for Python:
1970
1971 "The consensus of researchers in this area (at least as
1972 expressed at the NIST Hash Function Workshop 10/31/05),
1973 is that SHA-256 is a good choice for the time being, but
1974 that research should continue, and other alternatives may
1975 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001976
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001977- Added a subset of Fredrik Lundh's ElementTree package. Available

2039
Guido van Rossum755149f2005-07-27 00:00:44 +00002040- Fix a problem in Tkinter introduced by SF patch #869468: delete bogus
2041 __hasattr__ and __delattr__ methods on class Tk that were breaking
2042 Tkdnd.
2043
Georg Brandl5dbda752005-07-17 20:27:41 +00002044- Bug #1015140: disambiguated the term "article id" in nntplib docs and
2045 docstrings to either "article number" or "message id".
2046
Georg Brandla4a8b822005-07-15 09:13:21 +00002047- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
2048 parameter, but uses the usual "kwargs=None".
2049
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002050- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00002051 Patch #1209527 (Contributed by Connelly).
2052
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002053- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2054 to W3C name (404 -> 'Not Found'). RFE #1216944.
2055
Georg Brandl9e43acf2005-07-04 17:16:07 +00002056- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2057 as this can cause problems with apps closing all file descriptors.
2058
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002059- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002060 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00002061
Georg Brandl2f210b62005-06-26 22:09:06 +00002062- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2063
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002064- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2065 error messages.
2066
Georg Brandl379f99d2005-06-26 21:09:38 +00002067- Bug #1108948: Cookie.py produced invalid JavaScript code.
2068
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002069- The tokenize module now detects and reports indentation errors.
2070 Bug #1224621.
2071
Raymond Hettinger68c04532005-06-10 11:05:19 +00002072- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002073 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002074 the generate_tokens() function now accepts a callable argument that
2075 terminates by raising StopIteration.
2076
Georg Brandl9166e1a2005-06-04 09:20:03 +00002077- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2078
Georg Brandl268e61c2005-06-03 14:28:50 +00002079- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2080 component of the path.
2081
Skip Montanaro174dd222005-05-14 20:54:16 +00002082- Patch #1120353: The xmlrpclib module provides better, more transparent,
2083 support for datetime.{datetime,date,time} objects. With use_datetime set
2084 to True, applications shouldn't have to fiddle with the DateTime wrapper
2085 class at all.
2086
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002087- distutils.commands.upload was added to support uploading distribution
2088 files to PyPI.
2089
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002090- distutils.commands.register now encodes the data as UTF-8 before posting
2091 them to PyPI.
2092
Raymond Hettinger267b8682005-03-27 10:47:39 +00002093- decimal operator and comparison methods now return NotImplemented
2094 instead of raising a TypeError when interacting with other types. This
2095 allows other classes to implement __radd__ style methods and have them
2096 work as expected.
2097
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002098- Bug #1163325: Decimal infinities failed to hash. Attempting to
2099 hash a NaN raised an InvalidOperation instead of a TypeError.
2100
Tim Petersecc6e6a2005-07-10 22:30:55 +00002101- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002102 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2103

2135
Guido van Rossumd0641422005-02-03 15:01:24 +00002136- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2137 disables recursive traversal through instance attributes, which can
2138 be exploited in various ways.
2139
Tim Peterse3547fd2005-12-16 23:13:57 +00002140- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002141 flags on the HTTP listening socket.
2142
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002143- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2144 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2145
Fred Drakefbdeaad2006-07-29 16:56:15 +00002146- Patches #893642, #1039083: add allow_none, encoding arguments to
2147 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002148
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002149- Bug #1110478: Revert os.environ.update to do putenv again.
2150
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002151- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2152
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002153- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2154
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002155- Enhancements to the csv module:
2156
2157 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002158 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002159 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002160 + Dialect parameter parsing has been re-implemented to improve error
2161 reporting.
2162 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2163 dictates.
2164 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002165 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002166 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002167 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2168 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002169 + reader now allows \r characters to be quoted (previously it only allowed
2170 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002171 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002172 + Dialect classes passed to the module are no longer instantiated by
2173 the module before being parsed (the former validation scheme required
2174 this, but the mechanism was unreliable).
2175 + The dialect registry now contains instances of the internal
2176 C-coded dialect type, rather than references to python objects.
2177 + the internal c-coded dialect type is now immutable.
2178 + register_dialect now accepts the same keyword dialect specifications
2179 as the reader and writer, allowing the user to register dialects
2180 without first creating a dialect class.
2181 + a configurable limit to the size of parsed fields has been added -
2182 previously, an unmatched quote character could result in the entire
2183 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002184 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002185 the parser field size limit (returning the former limit). The initial
2186 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002187 + A line_num attribute has been added to the reader object, which tracks
2188 the number of lines read from the source iterator. This is not
2189 the same as the number of records returned, as records can span
2190 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002191 + reader and writer objects were not being registered with the cyclic-GC.
2192 This has been fixed.
2193
Brett Cannone6539c42005-01-08 02:43:53 +00002194- _DummyThread objects in the threading module now delete self.__block that is
2195 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2196 lock primitives tend to be limited in number and thus should not be wasted on
2197 a _DummyThread object. Fixes bug #1089632.
2198
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002199- The imghdr module now detects Exif files.
2200
Raymond Hettinger6065d322004-12-20 23:51:53 +00002201- StringIO.truncate() now correctly adjusts the size attribute.
2202 (Bug #951915).
2203
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002204- locale.py now uses an updated locale alias table (built using
2205 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2206 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002207 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002208
Raymond Hettinger3557f422004-12-07 12:02:02 +00002209- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2210
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002211- the pickle module no longer accepts the deprecated None option in the
2212 args tuple returned by __reduce__().
2213
Brett Cannon84667c02004-12-07 03:25:18 +00002214- optparse now optionally imports gettext. This allows its use in setup.py.
2215
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002216- the pickle module no longer uses the deprecated bin parameter.
2217
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002218- the shelve module no longer uses the deprecated binary parameter.
2219
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002220- the pstats module no longer uses the deprecated ignore() method.
2221
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002222- the filecmp module no longer uses the deprecated use_statcache argument.
2223
Raymond Hettinger664347b2004-12-04 21:21:53 +00002224- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2225 extended or overridden by subclasses. Formerly, the subclassed method would
2226 be ignored by the rest of the module. (Bug #1078905).
2227
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002228- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002229 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002230
Walter Dörwald36733692004-12-22 12:50:50 +00002231- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2232 once when a size argument is given. This prevents a buffer overflow in the
2233 tokenizer with very long source lines.
2234
Barry Warsaw538561e2006-01-01 21:48:54 +00002235- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2236 immediately after creating the object, without any intervening
2237 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002238
Skip Montanaro05885812005-01-16 20:48:27 +00002239- The reconvert.quote function can now emit triple-quoted strings. The
2240 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002241
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002242- ``UserString.MutableString`` now supports negative indices in
2243 ``__setitem__`` and ``__delitem__``
2244
Greg Ward40407942005-03-05 02:53:17 +00002245- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2246 correctly.
2247
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002248- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2249 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2250 character even if the user has passed a size parameter to get a proper
2251 line ending. Remove the special handling of a "\r\n" that has been split
2252 between two lines.
2253
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002254- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2255 about illegal code points. The codec now supports PEP 293 style error
2256 handlers.
2257
Walter Dörwald78a78b02005-09-01 12:04:29 +00002258- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002259 from the input stream, so that the output is a byte string in the correct
2260 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002261
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002262- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2263 considering it exactly like a '*'.
2264
Walter Dörwald007f8df2005-10-09 19:42:27 +00002265- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2266 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002267
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002268- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2269
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002270- Patch #1413711: Certain patterns of differences were making difflib
2271 touch the recursion limit.
2272
Walter Dörwald58917a62006-03-31 15:26:22 +00002273- Bug #947906: An object oriented interface has been added to the calendar
2274 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002275 called as a script (e.g. via ``python -mcalendar``). Localized month and
2276 weekday names can be ouput (even if an exotic encoding is used) using
2277 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002278

Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002293- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2294 The zlib module is now builtin on Windows.
2295
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002296- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2297
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002298- Bug #1189330: configure did not correctly determine the necessary
2299 value of LINKCC if python was built with GCC 4.0.
2300
Trent Mick8321b422005-07-26 02:29:21 +00002301- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2302 vulnerability in zlib 1.2.1 and 1.2.2.
2303
Brett Cannon08cd5982005-04-24 22:26:38 +00002304- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2305 flags that change binary compatibility. Changes were also made to
2306 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002307 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002308
Bob Ippolitoed233462005-03-29 13:47:59 +00002309- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2310 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2311 no longer exists). This configure patch makes things right.
2312
Martin v. Löwise2713be2005-03-08 15:03:08 +00002313- Bug #1158607: Build with --disable-unicode again.
2314
Brett Cannon46d96232005-02-16 00:07:19 +00002315- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2316 defined. Discovered as a result of not being able to build on OS X.
2317
Brett Cannon516592f2004-12-07 00:42:59 +00002318- setup.py now uses the directories specified in LDFLAGS using the -L option
2319 and in CPPFLAGS using the -I option for adding library and include
2320 directories, respectively, for compiling extension modules against. This has
2321 led to the core being compiled using the values in CPPFLAGS. It also removes
2322 the need for the special-casing of both DarwinPorts and Fink for darwin since
2323 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2324 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2325 Fink, ``-I/opt/local/include`` for DarwinPorts).
2326
Brett Cannon43802422005-02-10 20:48:03 +00002327- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2328 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2329 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2330 Closes bug #1096244. Thanks Gregory Bond.

2333-----
2334
Tim Petersc9d78aa2006-03-26 23:27:58 +00002335- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2336 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2337 is obtained via the ``PyObject_`` family, it must be released via the
2338 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2339 always been officially true, but when Python's small-object allocator was
2340 introduced, an attempt was made to cater to a few extension modules
2341 discovered at the time that obtained memory via ``PyObject_New`` but
2342 released it via ``PyMem_DEL``. It's years later, and if such code still
2343 exists it will fail now (probably with segfaults, but calling wrong
2344 low-level memory management functions can yield many symptoms).
2345
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002346- Added a C API for set and frozenset objects.
2347

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002350- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2351 mapping argument now. This string is used as a mapping table. Byte values
2352 greater than the length of the string and 0xFFFE are treated as undefined
2353 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002360
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002361- Patch #1276356: New resource "urlfetch" is implemented. This enables
2362 even impatient people to run tests that require remote files.
