12Core and builtins
13-----------------
14
Georg Brandl846f73a2006-10-08 07:11:54 +000015- Bug #1569998: break inside a try statement (outside a loop) is now
16 recognized and rejected.
17
Armin Rigo7ccbca92006-10-04 12:17:45 +000018- list.pop(x) accepts any object x following the __index__ protocol.
19
20- Fix some leftovers from the conversion from int to Py_ssize_t
21 (relevant to strings and sequences of more than 2**31 items).
22
23- A number of places, including integer negation and absolute value,
24 were fixed to not rely on undefined behaviour of the C compiler
25 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +000026
Georg Brandl3267d282006-09-30 09:03:42 +000027- Bug #1566800: make sure that EnvironmentError can be called with any
28 number of arguments, as was the case in Python 2.4.
29
Georg Brandl5d59c092006-09-30 08:43:30 +000030- Patch #1567691: super() and new.instancemethod() now don't accept
31 keyword arguments any more (previously they accepted them, but didn't
32 use them).
33
Georg Brandla10d3af2006-09-24 12:35:36 +000034- Fix a bug in the parser's future statement handling that led to "with"
35 not being recognized as a keyword after, e.g., this statement:
36 from __future__ import division, with_statement
37
Neal Norwitz3a230172006-09-22 08:18:10 +000038- Bug #1557232: fix seg fault with def f((((x)))) and def f(((x),)).

43
Brett Cannon9adeab72006-09-20 18:34:28 +000044- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
45 allows calling unicode() on exceptions classes directly to succeed.
46
Georg Brandlec6c2df2006-09-11 09:38:35 +000047- Make _PyGILState_NoteThreadState() static, it was not used anywhere
48 outside of pystate.c and should not be necessary.
49
Georg Brandl4e933132006-09-06 20:05:58 +000050- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
51 Also make sure that every exception class has __module__ set to
52 'exceptions'.
53
Georg Brandl98775df2006-09-06 06:09:31 +000054- Bug #1550983: emit better error messages for erroneous relative
55 imports (if not in package and if beyond toplevel package).
56
Tim Petersc10c9d02006-09-05 02:18:09 +000057- Overflow checking code in integer division ran afoul of new gcc
58 optimizations. Changed to be more standard-conforming.
59
Neal Norwitz4f096d92006-08-21 19:47:08 +000060- Patch #1542451: disallow continue anywhere under a finally.
61
Neal Norwitza22975f2006-09-05 02:24:03 +000062- Patch #1546288: fix seg fault in dict_equal due to ref counting bug.

Neal Norwitzd34e4272006-09-05 02:36:20 +000064- The return tuple from str.rpartition(sep) is (tail, sep, head) where
65 head is the original string if sep was not found.
66
Neal Norwitzdac090d2006-09-05 03:53:08 +000067- Bug #1520864: unpacking singleton tuples in list comprehensions and
68 generator expressions (x for x, in ... ) works again. Fixing this problem
69 required changing the .pyc magic number. This means that .pyc files
70 generated before 2.5c2 will be regenerated.
71
Neal Norwitzca460d92006-09-06 06:28:06 +000072- with and as are now keywords.

102
Georg Brandlc7986ce2006-09-24 12:50:24 +0000103- Fix a bug in traceback.format_exception_only() that led to an error
104 being raised when print_exc() was called without an exception set.
105 In version 2.4, this printed "None", restored that behavior.
106
Georg Brandl2c94bf72006-09-24 10:36:01 +0000107- Make webbrowser.BackgroundBrowser usable in Windows (it wasn't because

133
Georg Brandl5597e262006-10-12 09:47:12 +0000134- Bug #1548891: The cStringIO.StringIO() constructor now encodes unicode
135 arguments with the system default encoding just like the write()
136 method does, instead of converting it to a raw buffer.
137
Georg Brandl412a9ea2006-10-09 19:03:06 +0000138- Patch #1572724: fix typo ('=' instead of '==') in _msi.c.

Andrew M. Kuchling43889c02006-09-27 16:37:30 +0000164- Bug #1552726: in readline.c, avoid repeatedly polling in interactive
165 mode by only placing a timeout on the select() if an input hook has
166 been defined. This prevents an interactive Python from waking up 10
167 times per second. Patch by Richard Boulton.

Guido van Rossumc69ac252006-08-10 18:09:25 +0000224What's New in Python 2.5 release candidate 1?
225=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000226
Anthony Baxterb4096662006-08-16 03:42:26 +0000227*Release date: 17-AUG-2006*

229Core and builtins
230-----------------
231
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000232- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000233 compared equal or unequal to a string and a UnicodeDecodeError
234 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000235
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000236 Instead, the equal (==) and unequal (!=) comparison operators will
237 now issue a UnicodeWarning and interpret the two objects as
238 unequal. The UnicodeWarning can be filtered as desired using
239 the warning framework, e.g. silenced completely, turned into an
240 exception, logged, etc.
241
242 Note that compare operators other than equal and unequal will still
243 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000244
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000245- Fix segfault when doing string formatting on subclasses of long.
246
247- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
248 with new-style classes.
249
250- Fix bug related to __len__ functions returning negative values with
251 classic classes.
252
253- Patch #1538606, Fix __index__() clipping. There were some problems
254 discovered with the API and how integers that didn't fit into Py_ssize_t
255 were handled. This patch attempts to provide enough alternatives
256 to effectively use __index__.
257
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000258- Bug #1536021: __hash__ may now return long int; the final hash
259 value is obtained by invoking hash on the long int.
260
Thomas Hellerab1049c2006-08-08 17:37:00 +0000261- Bug #1536786: buffer comparison could emit a RuntimeWarning.
262
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000263- Bug #1535165: fixed a segfault in input() and raw_input() when
264 sys.stdin is closed.
265
Thomas Heller74d36f02006-08-04 18:17:40 +0000266- On Windows, the PyErr_Warn function is now exported from
267 the Python dll again.
268
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000269- Bug #1191458: tracing over for loops now produces a line event
270 on each iteration. Fixing this problem required changing the .pyc
271 magic number. This means that .pyc files generated before 2.5c1
272 will be regenerated.
273
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000274- Bug #1333982: string/number constants were inappropriately stored
275 in the byte code and co_consts even if they were not used, ie
276 immediately popped off the stack.
277
Georg Brandle9462c72006-08-04 18:03:37 +0000278- Fixed a reference-counting problem in property().
279
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000280
281Library
282-------
283
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000284- Fix a bug in the ``compiler`` package that caused invalid code to be
285 generated for generator expressions.
286
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000287- The distutils version has been changed to 2.5.0. The change to
288 keep it programmatically in sync with the Python version running
289 the code (introduced in 2.5b3) has been reverted. It will continue
290 to be maintained manually as static string literal.
291
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000292- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000293 and this cannot be converted to the required C type, an exception is
294 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000295 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000296
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000297- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000298 an exception.
299
Tim Petersc10c9d02006-09-05 02:18:09 +0000300- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000301 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000302 workarounds for clocks with low resolution, to stop the code yielding
303 duplicate UUIDs.
304
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000305- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
306 before raising SystemExit, allowing IDLE to honor quit() and exit().
307
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000308- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
309
Georg Brandl7a1af772006-08-14 21:55:28 +0000310- Patch #1536071: trace.py should now find the full module name of a
311 file correctly even on Windows.
312
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000313- logging's atexit hook now runs even if the rest of the module has
314 already been cleaned up.
315
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000316- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000317
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000318- Bug #1531405, format_exception no longer raises an exception if
319 str(exception) raised an exception.
320

335
Thomas Heller86720042006-08-14 11:17:48 +0000336- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
337 uses the _as_parameter_ attribute when objects are passed to foreign
338 function calls. The ctypes version number was changed to 1.0.1.
339
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000340- Bug #1530559, struct.pack raises TypeError where it used to convert.

357
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000358

Fred Drake53912162006-07-29 13:22:49 +0000387What's New in Python 2.5 beta 3?
388================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000389
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000390*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000391
392Core and builtins
393-----------------
394
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000395- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000396 returned a long (see PEP 353).
397
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000398- Bug #1515471: string.replace() accepts character buffers again.
399
Neal Norwitz07aadb12006-07-30 06:55:48 +0000400- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
401 This provides the proper warning for struct.pack().
402 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
403
Neal Norwitz0d62a062006-07-30 06:53:31 +0000404- Patch #1531113: Fix augmented assignment with yield expressions.
405 Also fix a SystemError when trying to assign to yield expressions.
406
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000407- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
408 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
409 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
410 excessive filesystem operations during imports.
411
Tim Petersbc24eee2006-07-27 01:14:53 +0000412- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
413 operations on signed longs that are formally undefined by C.
414 Unfortunately, at least one compiler now cares about that, so complicated
415 the code to make that compiler happy again.
416
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000417- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
418
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000419- Patch #1232023: Stop including current directory in search
420 path on Windows.
421
Neal Norwitze1fdb322006-07-21 05:32:28 +0000422- Fix some potential crashes found with failmalloc.
423
Neal Norwitze7563102006-07-17 01:00:16 +0000424- Fix warnings reported by Klocwork's static analysis tool.
425
Neal Norwitz84be93b2006-07-16 01:50:38 +0000426- Bug #1512814, Fix incorrect lineno's when code within a function
427 had more than 255 blank lines.
428
Georg Brandl9dceedb2006-07-12 15:31:17 +0000429- Patch #1521179: Python now accepts the standard options ``--help`` and
430 ``--version`` as well as ``/?`` on Windows.
431
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000432- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000433 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000434 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000435
Tim Peters112aad32006-07-19 00:03:19 +0000436- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000437 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000438 new ``sys._current_frames()`` returns a dictionary with one entry,
439 mapping the faux "thread id" 0 to the current frame.
440
Ronald Oussoren3075e162006-07-25 20:28:55 +0000441- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000442
Ronald Oussoren3075e162006-07-25 20:28:55 +0000443
Neal Norwitza1f10902006-07-12 07:28:29 +0000444Library
445-------
446
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000447- Correction of patch #1455898: In the mbcs decoder, set final=False
448 for stream decoder, but final=True for the decode function.
449
Georg Brandl07fec3a2006-08-01 18:49:24 +0000450- os.urandom no longer masks unrelated exceptions like SystemExit or
451 KeyboardInterrupt.
452
Tim Peters4643c2f2006-08-10 22:45:34 +0000453- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000454 shutil.copytree on Windows
455
Georg Brandle34ac7c2006-07-30 11:07:23 +0000456- Bug #1002398: The documentation for os.path.sameopenfile now correctly
457 refers to file descriptors, not file objects.
458
Tim Petersc10c9d02006-09-05 02:18:09 +0000459- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000460 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000461 #1513611, and probably others.
462
Georg Brandledd9b0d2006-07-29 09:33:26 +0000463- Bug #1441397: The compiler module now recognizes module and function
464 docstrings correctly as it did in Python 2.4.
465
Tim Peters6f681472006-07-27 23:44:37 +0000466- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
467 lost that tests are sorted by name before being run. This rarely
468 matters for well-written tests, but can create baffling symptoms if
469 side effects from one test to the next affect outcomes. ``DocTestFinder``
470 has been changed to sort the list of tests it returns.
471
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000472- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000473 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000474
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000475- Bug #978833: Really close underlying socket in _socketobject.close.
476
Georg Brandl8c036cc2006-08-20 13:15:39 +0000477- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
478 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000479
Georg Brandlcf0c1722006-07-26 07:23:32 +0000480- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
481 to recursive calls and call it with the failing package name.
482
Martin v. Löwis0b483032006-07-25 09:53:12 +0000483- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
484
Georg Brandlc13c34c2006-07-24 14:09:56 +0000485- Patch #1515343: Fix printing of deprecated string exceptions with a
486 value in the traceback module.
487
Greg Ward48fae7a2006-07-23 16:05:51 +0000488- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
489
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000490- Patch #1524429: Use repr() instead of backticks in Tkinter again.
491
Brett Cannoncaebe222006-07-18 04:41:36 +0000492- Bug #1520914: Change time.strftime() to accept a zero for any position in its
493 argument tuple. For arguments where zero is illegal, the value is forced to
494 the minimum value that is correct. This is to support an undocumented but
495 common way people used to fill in inconsequential information in the time
496 tuple pre-2.4.
497
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000498- Patch #1220874: Update the binhex module for Mach-O.
499
Barry Warsawb110bad2006-07-21 14:51:07 +0000500- The email package has improved RFC 2231 support, specifically for
501 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
502 (name*0=<blah>) parameter continuations. This may change the types of
503 values returned from email.message.Message.get_param() and friends.
504 Specifically in some cases where non-encoded continuations were used,
505 get_param() used to return a 3-tuple of (None, None, string) whereas now it
506 will just return the string (since non-encoded continuations don't have
507 charset and language parts).
508
509 Also, whereas % values were decoded in all parameter continuations, they are
510 now only decoded in encoded parameter parts.
511
Ronald Oussoren3075e162006-07-25 20:28:55 +0000512- Bug #1517990: IDLE keybindings on MacOS X now work correctly
513
514- Bug #1517996: IDLE now longer shows the default Tk menu when a
515 path browser, class browser or debugger is the frontmost window on MacOS X
516
Barry Warsaw00decd72006-07-27 23:43:15 +0000517- Patch #1520294: Support for getset and member descriptors in types.py,
518 inspect.py, and pydoc.py. Specifically, this allows for querying the type
519 of an object against these built-in types and more importantly, for getting
520 their docstrings printed in the interactive interpreter's help() function.

525
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000526- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
527 a socket operation on a socket with a timeout, the exception will be
528 caught correctly. Previously, the exception was not caught.
529
Thomas Heller1393d6a2006-07-28 21:43:20 +0000530- Patch #1529514: The _ctypes extension is now compiled on more
531 openbsd target platforms.
532
Tim Peters9cab5932006-07-28 00:30:00 +0000533- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
534 a memory leak, affecting pickles and deep copies.
535
Tim Petersbc24eee2006-07-27 01:14:53 +0000536- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

538
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000539- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
540
Thomas Hellerce049a02006-07-14 17:51:14 +0000541- Patch #1521817: Index range checking on ctypes arrays containing
542 exactly one element enabled again. This allows iterating over these
543 arrays, without the need to check the array size before.
544
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000545- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000546 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000547 /dev/null in certain cases; this is now fixed.
548
Thomas Heller47d7a062006-07-12 08:43:47 +0000549- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
550 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000551
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000552- Because of a misspelled preprocessor symbol, ctypes was always
553 compiled without thread support; this is now fixed.
554
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000555- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
556 methods now allow their database parameter to be None as the
557 sleepycat API allows.
558
Matt Flemingec926502006-07-28 11:27:27 +0000559- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
560 bluetooth API compared with Linux and FreeBSD.
561
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000562Tests
563-----
564
565- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
566 how long the test file should take to play. Now accepts taking 2.93 secs
567 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
568
Georg Brandl4793aa32006-07-28 18:31:39 +0000569- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
570 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
571 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000578Mac
579---
580
581- PythonLauncher now works correctly when the path to the script contains
582 characters that are treated specially by the shell (such as quotes).
583
584- Bug #1527397: PythonLauncher now launches scripts with the working directory
585 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000586 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000587 expect.

599 again evaluates to a int object, not a long.
600
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000601- Bug #1501934: The scope of global variables that are locally assigned

Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000610- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
611 omit a default "error" argument for NULL pointer. This allows
612 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000613
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000614- Bug #1519018: 'as' is now validated properly in import statements.
615
Neal Norwitz28746ab2006-07-09 22:14:42 +0000616- On 64 bit systems, int literals that use less than 64 bits are
617 now ints rather than longs.
618
Neal Norwitzed657552006-07-10 00:04:44 +0000619- Bug #1512814, Fix incorrect lineno's when code at module scope
620 started after line 256.
621
Tim Peters32a83612006-07-10 21:08:24 +0000622- New function ``sys._current_frames()`` returns a dict mapping thread
623 id to topmost thread stack frame. This is for expert use, and is
624 especially useful for debugging application deadlocks. The functionality
625 was previously available in Fazal Majid's ``threadframe`` extension
626 module, but it wasn't possible to do this in a wholly threadsafe way from
627 an extension.

674
Brett Cannon53ab5b72006-06-22 16:49:14 +0000675- Bug #1510580: The 'warnings' module improperly required that a Warning
676 category be either a types.ClassType and a subclass of Warning. The proper
677 check is just that it is a subclass with Warning as the documentation states.
678
Georg Brandlad29e632006-06-21 17:45:17 +0000679- The compiler module now correctly compiles the new try-except-finally

692-----------------
693
Tim Peters112aad32006-07-19 00:03:19 +0000694- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
695 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
696 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000697
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000698- Assigning None to pointer type fields in ctypes structures possible
699 overwrote the wrong fields, this is fixed now.
700
701- Fixed a segfault in _ctypes when ctypes.wintypes were imported
702 on non-Windows platforms.
703
704- Bug #1518190: The ctypes.c_void_p constructor now accepts any
705 integer or long, without range checking.
706
707- Patch #1517790: It is now possible to use custom objects in the ctypes
708 foreign function argtypes sequence as long as they provide a from_param
709 method, no longer is it required that the object is a ctypes type.
710
711- The '_ctypes' extension module now works when Python is configured
712 with the --without-threads option.

729
Tim Peters32a83612006-07-10 21:08:24 +0000730- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000731 Previously, the slight difference could cause compilation errors of the
732 'zlib' module on systems with more than one version of zlib.
733
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000734- The MSI compileall step was fixed to also support a TARGETDIR

765Core and builtins
766-----------------
767
Georg Brandla56b9152006-06-19 06:35:54 +0000768- Patch #1507676: Error messages returned by invalid abstract object operations
769 (such as iterating over an integer) have been improved and now include the
770 type of the offending object to help with debugging.
771
Brett Cannonea3912b2006-06-13 21:46:41 +0000772- Bug #992017: A classic class that defined a __coerce__() method that returned
773 its arguments swapped would infinitely recurse and segfault the interpreter.
774
Neal Norwitz909eb122006-06-12 02:13:21 +0000775- Fix the socket tests so they can be run concurrently.
776
Neal Norwitzb9845e72006-06-12 02:11:18 +0000777- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000778 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000779
Brett Cannon22565aa2006-06-09 22:31:23 +0000780- Bug #532646: object.__call__() will continue looking for the __call__
781 attribute on objects until one without one is found. This leads to recursion
782 when you take a class and set its __call__ attribute to an instance of the
783 class. Originally fixed for classic classes, but this fix is for new-style.
784 Removes the infinite_rec_3 crasher.
785
Georg Brandl24250812006-06-09 18:45:48 +0000786- The string and unicode methods startswith() and endswith() now accept
787 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
788
Brett Cannonde3b0522006-06-08 17:00:45 +0000789- Buffer objects, at the C level, never used the char buffer
790 implementation even when the char buffer for the wrapped object was
791 explicitly requested (originally returned the read or write buffer).
792 Now a TypeError is raised if the char buffer is not present but is
793 requested.
794
Georg Brandlddbaa662006-06-04 21:56:52 +0000795- Patch #1346214: Statements like "if 0: suite" are now again optimized
796 away like they were in Python 2.4.
797
Georg Brandlb7c8f542006-05-27 12:30:25 +0000798- Builtin exceptions are now full-blown new-style classes instead of
799 instances pretending to be classes, which speeds up exception handling
800 by about 80% in comparison to 2.5a2.
801
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000802- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
803 Unicode 4.1.
804
Georg Brandlf4ef1162006-05-26 18:03:31 +0000805- Patch #921466: sys.path_importer_cache is now used to cache valid and
806 invalid file paths for the built-in import machinery which leads to
807 fewer open calls on startup.
808
Tim Peters696cf432006-05-24 21:10:40 +0000809- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
810 of-2 bases. The largest speedup is for inputs with about 1000 decimal
811 digits. Conversion from non-power-of-2 bases remains quadratic-time in
812 the number of input digits (it was and remains linear-time for bases
813 2, 4, 8, 16 and 32).
814
Tim Petersb713ec22006-05-23 18:45:30 +0000815- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
816 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
817 an integer close to ``sys.maxint``. This was repaired by patch
818 #1335972, which also gives a nice speedup.
819
Richard Jonescebbefc2006-05-23 18:28:17 +0000820- Patch #1337051: reduced size of frame objects.
821
822- PyErr_NewException now accepts a tuple of base classes as its
823 "base" parameter.
824
Richard Jones7c88dcc2006-05-23 10:37:38 +0000825- Patch #876206: function call speedup by retaining allocated frame
826 objects.
827
Georg Brandl7b90e162006-05-18 07:01:27 +0000828- Bug #1462152: file() now checks more thoroughly for invalid mode
829 strings and removes a possible "U" before passing the mode to the
830 C library function.
831
Neal Norwitz1004a532006-05-15 07:17:23 +0000832- Patch #1488312, Fix memory alignment problem on SPARC in unicode
833
Neal Norwitz373f0a72006-05-15 07:04:36 +0000834- Bug #1487966: Fix SystemError with conditional expression in assignment
835
Martin v. Löwis879768d2006-05-11 13:28:43 +0000836- WindowsError now has two error code attributes: errno, which carries
837 the error values from errno.h, and winerror, which carries the error
838 values from winerror.h. Previous versions put the winerror.h values
839 (from GetLastError()) into the errno attribute.
840
Martin v. Löwis77736712006-05-04 05:51:03 +0000841- Patch #1475845: Raise IndentationError for unexpected indent.
842
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000843- Patch #1479181: split open() and file() from being aliases for each other.
844
Tim Peters44bd9862006-06-01 13:49:23 +0000845- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
846 methods were always silently ignored by dictionaries when comparing keys.
847 They are now passed through (except when using the C API function
848 ``PyDict_GetItem()``, whose semantics did not change).
849
850- Bug #1456209: In some obscure cases it was possible for a class with a
851 custom ``__eq__()`` method to confuse dict internals when class instances
852 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
853 No, you don't have any code that did this ;-)

866
Nick Coghlanc649ec52006-05-29 12:43:05 +0000867- Patch #1478788 (modified version): The functional extension module has
868 been renamed to _functools and a functools Python wrapper module added.
869 This provides a home for additional function related utilities that are
870 not specifically about functional programming. See PEP 309.
871
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000872- Patch #1493701: performance enhancements for struct module.

881
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000882- On Win32, os.listdir now supports arbitrarily-long Unicode path names
883 (up to the system limit of 32K characters).
884
885- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
886 As a result, these functions now raise WindowsError instead of OSError.
887
Tim Peters7a822da2006-05-25 21:50:17 +0000888- ``time.clock()`` on Win64 should use the high-performance Windows
889 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
890 Windows platforms).
891
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000892- Calling Tk_Init twice is refused if the first call failed as that
893 may deadlock.
894
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000895- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
896 accept it without potentially using an uninitialized pointer.
897
898- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
899 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smith506f7b52006-06-15 08:52:32 +0000916- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000917 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000918 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
919 database calls that would previously deadlock. [SF python bug #775414]
920
Vinay Sajip28e57612006-07-01 10:45:20 +0000921- Patch #1446489: add support for the ZIP64 extensions to zipfile.

943 mime.types file for determining MIME types.
944
Georg Brandl2605ca82006-06-14 06:08:31 +0000945- Bug #1339007: Shelf objects now don't raise an exception in their
946 __del__ method when initialization failed.
947
Martin v. Löwisd8251432006-06-14 05:21:04 +0000948- Patch #1455898: The MBCS codec now supports the incremental mode for
949 double-byte encodings.
950
Tim Peters43898b42006-06-14 04:09:25 +0000951- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
952 guarantee that adjacent triples in the return list always describe
953 non-adjacent blocks. Previously, a pair of matching blocks could end
954 up being described by multiple adjacent triples that formed a partition
955 of the matching pair.
956
Greg Ward0e0c9f42006-06-11 16:24:11 +0000957- Bug #1498146: fix optparse to handle Unicode strings in option help,
958 description, and epilog.
959
Greg Wardd1c797e2006-06-11 14:42:41 +0000960- Bug #1366250: minor optparse documentation error.
961
Greg Ward7f547402006-06-11 00:40:49 +0000962- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
963 clarify docs.
964
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000965- The wsgiref package has been added to the standard library.
966
Nick Coghlan676725d2006-06-08 13:54:49 +0000967- The functions update_wrapper() and wraps() have been added to the functools
968 module. These make it easier to copy relevant metadata from the original
969 function when writing wrapper functions.
970
Tim Petersd6a9eef2006-06-05 01:48:21 +0000971- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
972 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000973
Martin v. Löwis3f767792006-06-04 19:36:28 +0000974- Patch #1359618: Speed up charmap encoder by using a trie structure
975 for lookup.
976
Tim Petersd609b1a2006-06-02 23:22:51 +0000977- The functions in the ``pprint`` module now sort dictionaries by key
978 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
979 if and only if its display required more than one line, although that
980 wasn't documented. The new behavior increases predictability; e.g.,
981 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
982
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000983- Patch #1497027: try HTTP digest auth before basic auth in urllib2
984 (thanks for J. J. Lee).
985
Georg Brandl2b330372006-05-28 20:23:12 +0000986- Patch #1496206: improve urllib2 handling of passwords with respect to
987 default HTTP and HTTPS ports.
988
George Yoshidaf3c65de2006-05-28 16:39:09 +0000989- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
990
Bob Ippolito7298f272006-05-23 18:43:47 +0000991- Patch #1281707: speed up gzip.readline.
992
Georg Brandlb89316f2006-05-17 15:51:16 +0000993- Patch #1180296: Two new functions were added to the locale module:
994 format_string() to get the effect of "format % items" but locale-aware,
995 and currency() to format a monetary number with currency sign.
996
Georg Brandle3a25832006-05-17 14:56:04 +0000997- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
998 and several features added, such as speed and geometry control.
999
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001000- Patch #1488881: add support for external file objects in bz2 compressed
1001 tarfiles.
1002
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001003- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1004 stdout arguments, making it possible to redirect input and output
1005 for remote debugging.
1006
1007- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1008 a couple of issues, notably handling of long file names using the
1009 GNU LONGNAME extension.
1010
1011- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1012 new flag when ``name`` is already the name of an option flag.
1013
1014- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1015 package.
1016
1017- Patch #1472854: make the rlcompleter.Completer class usable on non-
1018 UNIX platforms.
1019
1020- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1021
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001022- Bug #1472827: correctly escape newlines and tabs in attribute values in
1023 the saxutils.XMLGenerator class.

1058Core and builtins
1059-----------------
1060
Thomas Heller1b046642006-04-18 18:51:06 +00001061- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1062 by converting these apis from macros into exported functions again:
1063
1064 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1065 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1066 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1067 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1068 PyRun_String Py_CompileString
1069
Martin v. Löwis45294a92006-04-18 06:24:08 +00001070- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1071
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001072- All uses of PyStructSequence_InitType have been changed to initialize
1073 the type objects only once, even if the interpreter is initialized
1074 multiple times.
1075
Neal Norwitz61546162006-04-14 05:20:28 +00001076- Bug #1454485, array.array('u') could crash the interpreter. This was
1077 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1078 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1079
1080- Py_UNICODE is unsigned. It was always documented as unsigned, but
1081 due to a bug had a signed value in previous versions.
1082
Tim Peters3a5e8b12006-04-11 01:44:07 +00001083- Patch #837242: ``id()`` of any Python object always gives a positive
1084 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1085 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001086 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001087 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001088
Tim Peters3a5e8b12006-04-11 01:44:07 +00001089 def __hash__(self):
1090 return id(self) # WRONG
1091
1092 because a hash result must be a (short) Python int but it was always
1093 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001094 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001095 was always usable as a hash value before this patch. That's no longer
1096 necessarily so.
1097
1098- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001099 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001100 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001101 #1454844)
1102
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001103- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1104 involving generators that have paused outside of any ``try`` or ``with``
1105 blocks. (In 2.5a1, a paused generator that was part of a reference
1106 cycle could not be garbage collected, regardless of whether it was
1107 paused in a ``try`` or ``with`` block.)

1141 or exception is ignored).
1142
Nick Coghlanda2268f2006-04-24 04:37:15 +00001143- Fixed contextlib.nested to cope with exceptions being raised and
1144 caught inside exit handlers.
1145
Greg Wardab05edc2006-04-23 03:47:58 +00001146- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1147 hex, octal, or binary; add ``append_const`` action; keep going if
1148 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1149 added ``epilog`` for better help generation).
1150
Tim Peters21fbd572006-04-21 21:18:10 +00001151- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1152 called from a thread spawned as a side effect of importing a module.
1153
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001154- The pydoc module now supports documenting packages contained in
1155 .zip or .egg files.
1156
1157- The pkgutil module now has several new utility functions, such
1158 as ``walk_packages()`` to support working with packages that are either
1159 in the filesystem or zip files.
1160
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001161- The mailbox module can now modify and delete messages from

1163 K. Johnson for writing the code, and to the 2005 Google Summer of
1164 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001165
Tim Petersc7605f22006-04-17 21:12:33 +00001166- The ``__del__`` method of class ``local`` in module ``_threading_local``
1167 returned before accomplishing any of its intended cleanup.
1168
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001169- Patch #790710: Add breakpoint command lists in pdb.

Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001223- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1224 it separately and by hand. It also wasn't cleaning up its changes to
1225 the current Decimal context.
1226
Thomas Woutersabd08882006-04-26 15:53:30 +00001227- regrtest.py now has a -M option to run tests that test the new limits of
1228 containers, on 64-bit architectures. Running these tests is only sensible
1229 on 64-bit machines with more than two gigabytes of memory. The argument
1230 passed is the maximum amount of memory for the tests to use.

1239-------------
1240
Tim Petersb06d28c2006-05-12 01:57:59 +00001241- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1242
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001243- PEP 343: Added Context Types section to the library reference
1244 and attempted to bring other PEP 343 related documentation into
1245 line with the implementation and/or python-dev discussions.
1246
Tim Peters8dc73d22006-04-24 02:03:16 +00001247- Bug #1337990: clarified that ``doctest`` does not support examples
1248 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001251What's New in Python 2.5 alpha 1?
1252=================================
1253
Anthony Baxterebed3f62006-04-03 15:03:44 +00001254*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001255
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001256Core and builtins
1257-----------------
1258
Nick Coghlan43832302006-04-23 17:04:07 +00001259- PEP 338: -m command line switch now delegates to runpy.run_module
1260 allowing it to support modules in packages and zipfiles
1261
Martin v. Löwisc661b882006-04-20 04:54:23 +00001262- On Windows, .DLL is not an accepted file name extension for
1263 extension modules anymore; extensions are only found if they
1264 end in .PYD.
1265
Martin v. Löwisea62d252006-04-03 10:56:49 +00001266- Bug #1421664: sys.stderr.encoding is now set to the same value as
1267 sys.stdout.encoding.
1268
Neal Norwitz92e212f2006-04-03 04:48:37 +00001269- __import__ accepts keyword arguments.
1270
Georg Brandlccadf842006-03-31 18:54:53 +00001271- Patch #1460496: round() now accepts keyword arguments.
1272
Anthony Baxter262c00a2006-03-30 10:53:17 +00001273- Fixed bug #1459029 - unicode reprs were double-escaped.
1274
Hye-Shik Changd478f342006-03-23 12:32:36 +00001275- Patch #1396919: The system scope threads are reenabled on FreeBSD
1276 5.4 and later versions.
1277
Neal Norwitze98ccf62006-03-23 05:39:47 +00001278- Bug #1115379: Compiling a Unicode string with an encoding declaration
1279 now gives a SyntaxError.
1280
Georg Brandlabd1ff82006-03-18 07:59:59 +00001281- Previously, Python code had no easy way to access the contents of a
1282 cell object. Now, a ``cell_contents`` attribute has been added
1283 (closes patch #1170323).
1284
Tim Peterscf79aac2006-03-16 01:14:46 +00001285- Patch #1123430: Python's small-object allocator now returns an arena to
1286 the system ``free()`` when all memory within an arena becomes unused
1287 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1288 freed. Some applications will see a drop in virtual memory size now,
1289 especially long-running applications that, from time to time, temporarily
1290 use a large number of small objects. Note that when Python returns an
1291 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001292 platform C library will in turn return that memory to the operating system.
1293 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001294 appears to be effective at least on Microsoft C and gcc-based systems.
1295 Thanks to Evan Jones for hard work and patience.
1296
Georg Brandl533ff6f2006-03-08 18:09:27 +00001297- Patch #1434038: property() now uses the getter's docstring if there is
1298 no "doc" argument given. This makes it possible to legitimately use
1299 property() as a decorator to produce a read-only property.
1300
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001301- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1302 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1303 of requiring an int or long in slicing and a few other contexts, enabling
1304 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1305
Neal Norwitz995acdf2006-03-07 05:01:00 +00001306- Fixed various bugs reported by Coverity's Prevent tool.
1307
Brett Cannonbf364092006-03-01 04:25:17 +00001308- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1309 new exception base class, BaseException, which has a new message attribute.
1310 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1311 Raising a string exception now raises a DeprecationWarning.
1312
Thomas Woutersfb609f42006-02-28 16:37:25 +00001313- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1314 explicitly relative, using 'from .module import name' to mean 'from the same
1315 package as this module is in. Imports without dots still default to the
1316 old relative-then-absolute, unless 'from __future__ import
1317 absolute_import' is used.
1318
Brett Cannona7446e32006-02-27 23:39:10 +00001319- Properly check if 'warnings' raises an exception (usually when a filter set
1320 to "error" is triggered) when raising a warning for raising string
1321 exceptions.
1322
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001323- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001324 The name was removed from Include/code.h.
1325
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001326- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001327
Guido van Rossum1968ad32006-02-25 22:38:04 +00001328- Patch 1433928:
1329 - The copy module now "copies" function objects (as atomic objects).
1330 - dict.__getitem__ now looks for a __missing__ hook before raising
1331 KeyError.
1332
Tim Peters84ef21c2006-02-28 20:39:06 +00001333- PEP 343: with statement implemented. Needs ``from __future__ import
1334 with_statement``. Use of 'with' as a variable will generate a warning.
1335 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001336 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001337 The following objects have __context__ methods:
1338 - The built-in file type.
1339 - The thread.LockType type.
1340 - The following types defined by the threading module:
1341 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1342 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001343
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001344- Fix the encodings package codec search function to only search
1345 inside its own package. Fixes problem reported in patch #1433198.
1346
1347 Note: Codec packages should implement and register their own
1348 codec search function. PEP 100 has the details.
1349
Tim Peters9ea89d22006-06-04 03:26:02 +00001350- PEP 353: Using ``Py_ssize_t`` as the index type.
1351
1352- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1353 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1354 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1355 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1356 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001357
Neal Norwitzfc76d632006-01-10 06:03:13 +00001358- Patch #1400181, fix unicode string formatting to not use the locale.
1359 This is how string objects work. u'%f' could use , instead of .
1360 for the decimal point. Now both strings and unicode always use periods.
1361
Neal Norwitz671b9e32006-01-09 07:07:12 +00001362- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1363 configure would break checking curses.h.
1364
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001365- Bug #959576: The pwd module is now builtin. This allows Python to be
1366 built on UNIX platforms without $HOME set.
1367
Neal Norwitzc10978f2005-12-19 06:07:16 +00001368- Bug #1072182, fix some potential problems if characters are signed.
1369
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001370- Bug #889500, fix line number on SyntaxWarning for global declarations.
1371
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001372- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1373
Neal Norwitze7214a12005-12-18 05:03:17 +00001374- Support for converting hex strings to floats no longer works.
1375 This was not portable. float('0x3') now raises a ValueError.
1376
Barry Warsaw2a38a862005-12-18 01:27:35 +00001377- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001378 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001379 is now displayed in interactive prompt banner.
1380
Georg Brandlfa166682005-12-17 21:45:17 +00001381- Implementation of PEP 341 - Unification of try/except and try/finally.
1382 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001383 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001384
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001385- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1386 now encodes backslash correctly.
1387
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001388- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1389
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001390- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001391 and long longs.
1392
Neal Norwitz67715f02005-11-09 06:59:35 +00001393- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001394 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001395 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001396
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001397- Replaced most Unicode charmap codecs with new ones using the
1398 new Unicode translate string feature in the builtin charmap
1399 codec; the codecs were created from the mapping tables available
1400 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1401 encodings now include a mapping for the Apple logo)
1402
Tim Peterse3547fd2005-12-16 23:13:57 +00001403- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001404
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001405- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001406
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001407- A new AST parser implementation was completed. The abstract
1408 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001409 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001410
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001411- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001412 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1413
Neal Norwitz708e51a2005-10-03 04:48:15 +00001414- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1415
Neal Norwitz11bd1192005-10-03 00:54:56 +00001416- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1417 Provide a warning when a directory is passed on the command line.
1418
Neal Norwitz40d37812005-10-02 01:48:49 +00001419- Fix segfault with invalid coding.
1420
1421- SF bug #772896: unknown encoding results in MemoryError.
1422
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001423- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001424 supported a __len__() method which evaluated to False when the iterator
1425 was empty.
1426
Guido van Rossum630db602005-09-20 18:49:54 +00001427- On 64-bit platforms, when __len__() returns a value that cannot be
1428 represented as a C int, raise OverflowError.
1429
Skip Montanarof8948ca2005-09-19 03:54:46 +00001430- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001431 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001432
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001433- SF bug #893549: parsing keyword arguments was broken with a few format
1434 codes.
1435
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001436- Changes donated by Elemental Security to make it work on AIX 5.3
1437 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1438 bug #105470: test_pwd fails on 64bit system (Opteron).
1439
Guido van Rossum539c6622005-09-14 17:49:54 +00001440- Changes donated by Elemental Security to make it work on HP-UX 11 on
1441 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1442
Georg Brandl4550b8d2005-08-26 06:43:52 +00001443- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001444 (fixes bug #1119418).
1445
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001446- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1447
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001448- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1449 exceptions that cause a function to exit.
1450
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001451- The implementation of set() and frozenset() was revised to use its
1452 own internal data structure. Memory consumption is reduced by 1/3
1453 and there are modest speed-ups as well. The API is unchanged.
1454
Tim Petersde7990b2005-07-17 23:45:23 +00001455- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1456
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001457- SF bug #1229429: PyObject_CallMethod failed to decrement some
1458 reference counts in some error exit cases.
1459
Tim Petersecc6e6a2005-07-10 22:30:55 +00001460- SF bug #1185883: Python's small-object memory allocator took over
1461 a block managed by the platform C library whenever a realloc specified
1462 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001463 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001464 portable way to copy data from the C-managed block into Python's
1465 small-object space without risking a memory fault. Python's small-object
1466 realloc now leaves such blocks under the control of the platform C
1467 realloc.
1468
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001469- SF bug #1232517: An overflow error was not detected properly when
1470 attempting to convert a large float to an int in os.utime().
1471
Raymond Hettinger3296e692005-06-29 23:29:56 +00001472- SF bug #1224347: hex longs now print with lowercase letters just
1473 like their int counterparts.
1474
Michael W. Hudson188d4362005-06-20 16:52:57 +00001475- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1476 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1477 interpreter states; back out that fix and do a better job (see
1478 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1479 for a longer write-up of the problem).
1480
Michael W. Hudsondf888462005-06-03 14:41:55 +00001481- SF patch #1180995: marshal now uses a binary format by default when
1482 serializing floats.
1483
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001484- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1485 the routines that promise to produce IEEE 754 binary representations
1486 of floats now simply copy bytes around.
1487
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001488- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1489 278.
1490
Brett Cannonc3647ac2005-04-26 03:45:26 +00001491- patch #1109424: int, long, float, complex, and unicode now check for the
1492 proper magic slot for type conversions when subclassed. Previously the
1493 magic slot was ignored during conversion. Semantics now match the way
1494 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001495 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001496 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001497 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001498
Barry Warsawc8d907c2005-04-19 23:43:40 +00001499- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1500 NULL, now raise an AttributeError when attempting to set or delete the
1501 attribute. Previously a TypeError was raised, but this was inconsistent
1502 with the equivalent pure-Python implementation.
1503
Michael W. Hudson774479c2005-04-18 08:46:17 +00001504- It is now safe to call PyGILState_Release() before
1505 PyEval_InitThreads() (note that if there is reason to believe there
1506 are multiple threads around you still must call PyEval_InitThreads()
1507 before using the Python API; this fix is for extension modules that
1508 have no way of knowing if Python is multi-threaded yet).
1509
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001510- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1511 disabled caused a crash.
1512
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001513- Bug #1165306: instancemethod_new allowed the creation of a method
1514 with im_class == im_self == NULL, which caused a crash when called.
1515
Tim Petersecc6e6a2005-07-10 22:30:55 +00001516- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001517 fixes the crash seen in bug #1165761
1518
Raymond Hettinger96229b12005-03-11 06:49:40 +00001519- Added two new builtins, any() and all().
1520
Brett Cannon409d8f22005-03-05 06:47:57 +00001521- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001522 (e.g., ``class C(): pass`` is no longer a syntax error).
1523 Patch #1176012 added support to the 'parser' module and 'compiler' package
1524 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001525

1529 returning None.
1530
Tim Petersecc6e6a2005-07-10 22:30:55 +00001531- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001532 ('\') with a specific error message.
1533
Martin v. Löwisff232d72005-03-03 09:24:38 +00001534- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1535
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001536- Bug #1124295: the __name__ attribute of file objects was

1538
Tim Petersecc6e6a2005-07-10 22:30:55 +00001539- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001540 an ferror() call.
1541
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001542- min() and max() now support key= arguments with the same meaning as in
1543 list.sort().
1544
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001545- The peephole optimizer now performs simple constant folding in expressions:
1546 (2+3) --> (5).
1547
Raymond Hettingera422c342005-01-11 03:03:27 +00001548- set and frozenset objects can now be marshalled. SF #1098985.
1549
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001550- Bug #1077106: Poor argument checking could cause memory corruption
1551 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001552
Jeremy Hyltonab630502005-02-04 18:44:06 +00001553- The parser did not complain about future statements in illegal
1554 positions. It once again reports a syntax error if a future
1555 statement occurs after anything other than a doc string.
1556
Neil Schemenauercf52c072005-08-12 17:34:58 +00001557- Change the %s format specifier for str objects so that it returns a
1558 unicode instance if the argument is not an instance of basestring and
1559 calling __str__ on the argument returns a unicode instance.
1560
Tim Petersf4e69282006-02-27 17:15:31 +00001561- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1562 current thread state when the auto-GIL-state machinery knows about
1563 it (since the thread state is being deleted, continuing to remember it
1564 can't help, but can hurt if another thread happens to get created with
1565 the same thread id).

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001757- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1758 been renamed to have only a single underscore prefix. This was done to
1759 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001760
Nick Coghlan43832302006-04-23 17:04:07 +00001761- PEP 338: new module runpy defines a run_module function to support
1762 executing modules which provide access to source code or a code object
1763 via the PEP 302 import mechanisms.
1764
Anthony Baxter93f5b932006-04-03 08:05:07 +00001765- The email module's parsedate_tz function now sets the daylight savings
1766 flag to -1 (unknown) since it can't tell from the date whether it should

1773 in attribute values.
1774
Anthony Baxterc51ee692006-04-01 00:57:31 +00001775- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001776 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001777 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001778 module will not be built.
1779
Tim Petersc17976e2006-04-01 00:26:53 +00001780- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1781 aren't officially supported here, and trying to use them will probably
1782 raise an exception some day. But dicts have been allowed, and "mostly
1783 worked", so support for them won't go away without warning.
1784
Georg Brandl338ef7d2006-03-31 18:42:16 +00001785- Bug #1445068: getpass.getpass() can now be given an explicit stream
1786 argument to specify where to write the prompt.
1787

1794 key to be used for signing the uploaded code.
1795
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001796- Queue.Queue objects now support .task_done() and .join() methods
1797 to make it easier to monitor when daemon threads have completed
1798 processing all enqueued tasks. Patch #1455676.
1799
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001800- popen2.Popen objects now preserve the command in a .cmd attribute.
1801
Thomas Hellerc61c0492006-03-22 10:09:27 +00001802- Added the ctypes ffi package.
1803
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001804- email 4.0 package now integrated. This is largely the same as the email 3.0
1805 package that was included in Python 2.3, except that PEP 8 module names are
1806 now used (e.g. mail.message instead of email.Message). The MIME classes
1807 have been moved to a subpackage (e.g. email.mime.text instead of
1808 email.MIMEText). The old names are still supported for now. Several
1809 deprecated Message methods have been removed and lots of bugs have been
1810 fixed. More details can be found in the email package documentation.
1811
Walter Dörwald40108c92006-03-27 08:15:44 +00001812- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1813 (a subclass of tuple) that provides incremental decoders and encoders
1814 (a way to use stateful codecs without the stream API). Python functions
1815 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1816 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1817 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001818
Walter Dörwald067db482006-03-15 22:17:27 +00001819- Patch #1359365: Calling next() on a closed StringIO.String object raises
1820 a ValueError instead of a StopIteration now (like file and cString.String do).
1821 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1822 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001823
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001824- A regrtest option -w was added to re-run failed tests in verbose mode.

1827 interpreter to exit.
1828
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001829- The function get_count() has been added to the gc module, and gc.collect()
1830 grew an optional 'generation' argument.
1831

1836 and helpful context managers nested() and closing().
1837

1897 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1898 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1899 Ronald L. Rivest offered this advice for Python:
1900
1901 "The consensus of researchers in this area (at least as
1902 expressed at the NIST Hash Function Workshop 10/31/05),
1903 is that SHA-256 is a good choice for the time being, but
1904 that research should continue, and other alternatives may
1905 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001906
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001907- Added a subset of Fredrik Lundh's ElementTree package. Available

2018 files to PyPI.
2019
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002020- distutils.commands.register now encodes the data as UTF-8 before posting
2021 them to PyPI.
2022
Raymond Hettinger267b8682005-03-27 10:47:39 +00002023- decimal operator and comparison methods now return NotImplemented
2024 instead of raising a TypeError when interacting with other types. This
2025 allows other classes to implement __radd__ style methods and have them
2026 work as expected.
2027
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002028- Bug #1163325: Decimal infinities failed to hash. Attempting to
2029 hash a NaN raised an InvalidOperation instead of a TypeError.
2030
Tim Petersecc6e6a2005-07-10 22:30:55 +00002031- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002032 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2033
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002034- Patch #1043890: Add extractall method to tarfile.
2035
Martin v. Löwisc72dd382005-03-04 13:50:17 +00002036- Patch #1075887: Don't require MSVC in distutils if there is nothing
2037 to build.
2038
Martin v. Löwis637431b2005-03-03 23:12:42 +00002039- Patch #1103407: Properly deal with tarfile iterators when untarring
2040 symbolic links on Windows.
2041
Tim Petersecc6e6a2005-07-10 22:30:55 +00002042- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00002043 profile.py if available.
2044
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002045- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2046
Martin v. Löwisc5574e82005-03-03 10:57:37 +00002047- Patch #1117454: Remove code to special-case cookies without values
2048 in LWPCookieJar.
2049
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00002050- Patch #1117339: Add cookielib special name tests.
2051
Martin v. Löwise869eb12005-03-03 09:46:07 +00002052- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
2053
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00002054- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
2055
Martin v. Löwisdf241532005-03-03 08:17:42 +00002056- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
2057
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002058- Patch #1104111: Alter setup.py --help and --help-commands.
2059
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002060- Patch #1121234: Properly cleanup _exit and tkerror commands.
2061
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002062- Patch #1049151: xdrlib now unpacks booleans as True or False.
2063
Raymond Hettingerbab41432005-02-05 01:31:19 +00002064- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2065
Guido van Rossumd0641422005-02-03 15:01:24 +00002066- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2067 disables recursive traversal through instance attributes, which can
2068 be exploited in various ways.
2069
Tim Peterse3547fd2005-12-16 23:13:57 +00002070- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002071 flags on the HTTP listening socket.
2072
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002073- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2074 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2075
Fred Drakefbdeaad2006-07-29 16:56:15 +00002076- Patches #893642, #1039083: add allow_none, encoding arguments to
2077 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002078
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002079- Bug #1110478: Revert os.environ.update to do putenv again.
2080
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002081- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2082
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002083- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2084
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002085- Enhancements to the csv module:
2086
2087 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002088 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002089 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002090 + Dialect parameter parsing has been re-implemented to improve error
2091 reporting.
2092 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2093 dictates.
2094 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002095 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002096 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002097 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2098 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002099 + reader now allows \r characters to be quoted (previously it only allowed
2100 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002101 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002102 + Dialect classes passed to the module are no longer instantiated by
2103 the module before being parsed (the former validation scheme required
2104 this, but the mechanism was unreliable).
2105 + The dialect registry now contains instances of the internal
2106 C-coded dialect type, rather than references to python objects.
2107 + the internal c-coded dialect type is now immutable.
2108 + register_dialect now accepts the same keyword dialect specifications
2109 as the reader and writer, allowing the user to register dialects
2110 without first creating a dialect class.
2111 + a configurable limit to the size of parsed fields has been added -
2112 previously, an unmatched quote character could result in the entire
2113 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002114 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002115 the parser field size limit (returning the former limit). The initial
2116 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002117 + A line_num attribute has been added to the reader object, which tracks
2118 the number of lines read from the source iterator. This is not
2119 the same as the number of records returned, as records can span
2120 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002121 + reader and writer objects were not being registered with the cyclic-GC.
2122 This has been fixed.
2123
Brett Cannone6539c42005-01-08 02:43:53 +00002124- _DummyThread objects in the threading module now delete self.__block that is
2125 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2126 lock primitives tend to be limited in number and thus should not be wasted on
2127 a _DummyThread object. Fixes bug #1089632.
2128
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002129- The imghdr module now detects Exif files.
2130
Raymond Hettinger6065d322004-12-20 23:51:53 +00002131- StringIO.truncate() now correctly adjusts the size attribute.
2132 (Bug #951915).
2133
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002134- locale.py now uses an updated locale alias table (built using
2135 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2136 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002137 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002138
Raymond Hettinger3557f422004-12-07 12:02:02 +00002139- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2140
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002141- the pickle module no longer accepts the deprecated None option in the
2142 args tuple returned by __reduce__().
2143
Brett Cannon84667c02004-12-07 03:25:18 +00002144- optparse now optionally imports gettext. This allows its use in setup.py.
2145
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002146- the pickle module no longer uses the deprecated bin parameter.
2147
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002148- the shelve module no longer uses the deprecated binary parameter.
2149
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002150- the pstats module no longer uses the deprecated ignore() method.
2151
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002152- the filecmp module no longer uses the deprecated use_statcache argument.
2153
Raymond Hettinger664347b2004-12-04 21:21:53 +00002154- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2155 extended or overridden by subclasses. Formerly, the subclassed method would
2156 be ignored by the rest of the module. (Bug #1078905).
2157
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002158- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002159 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002160
Walter Dörwald36733692004-12-22 12:50:50 +00002161- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2162 once when a size argument is given. This prevents a buffer overflow in the
2163 tokenizer with very long source lines.
2164
Barry Warsaw538561e2006-01-01 21:48:54 +00002165- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2166 immediately after creating the object, without any intervening
2167 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002168
Skip Montanaro05885812005-01-16 20:48:27 +00002169- The reconvert.quote function can now emit triple-quoted strings. The
2170 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002171
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002172- ``UserString.MutableString`` now supports negative indices in
2173 ``__setitem__`` and ``__delitem__``
2174
Greg Ward40407942005-03-05 02:53:17 +00002175- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2176 correctly.
2177
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002178- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2179 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2180 character even if the user has passed a size parameter to get a proper
2181 line ending. Remove the special handling of a "\r\n" that has been split
2182 between two lines.
2183
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002184- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2185 about illegal code points. The codec now supports PEP 293 style error
2186 handlers.
2187
Walter Dörwald78a78b02005-09-01 12:04:29 +00002188- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002189 from the input stream, so that the output is a byte string in the correct
2190 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002191
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002192- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2193 considering it exactly like a '*'.
2194
Walter Dörwald007f8df2005-10-09 19:42:27 +00002195- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2196 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002197
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002198- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2199
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002200- Patch #1413711: Certain patterns of differences were making difflib
2201 touch the recursion limit.
2202
Walter Dörwald58917a62006-03-31 15:26:22 +00002203- Bug #947906: An object oriented interface has been added to the calendar
2204 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002205 called as a script (e.g. via ``python -mcalendar``). Localized month and
2206 weekday names can be ouput (even if an exotic encoding is used) using
2207 special classes that use unicode.

2211
Neal Norwitz602d3392006-03-31 08:21:40 +00002212- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2213 by using -mieee gcc option.
2214
Martin v. Löwis86d66262006-02-17 08:40:11 +00002215- Patch #1432345: Make python compile on DragonFly.
2216
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002217- Build support for Win64-AMD64 was added.
2218
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002219- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2220
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002221- Patch #881820: look for openpty and forkpty also in libbsd.
2222
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002223- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2224 The zlib module is now builtin on Windows.
2225
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002226- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2227
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002228- Bug #1189330: configure did not correctly determine the necessary
2229 value of LINKCC if python was built with GCC 4.0.
2230
Trent Mick8321b422005-07-26 02:29:21 +00002231- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2232 vulnerability in zlib 1.2.1 and 1.2.2.
2233
Brett Cannon08cd5982005-04-24 22:26:38 +00002234- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2235 flags that change binary compatibility. Changes were also made to
2236 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002237 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002238
Bob Ippolitoed233462005-03-29 13:47:59 +00002239- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2240 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2241 no longer exists). This configure patch makes things right.
2242
Martin v. Löwise2713be2005-03-08 15:03:08 +00002243- Bug #1158607: Build with --disable-unicode again.
2244
Brett Cannon46d96232005-02-16 00:07:19 +00002245- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2246 defined. Discovered as a result of not being able to build on OS X.
2247
Brett Cannon516592f2004-12-07 00:42:59 +00002248- setup.py now uses the directories specified in LDFLAGS using the -L option
2249 and in CPPFLAGS using the -I option for adding library and include
2250 directories, respectively, for compiling extension modules against. This has
2251 led to the core being compiled using the values in CPPFLAGS. It also removes
2252 the need for the special-casing of both DarwinPorts and Fink for darwin since
2253 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2254 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2255 Fink, ``-I/opt/local/include`` for DarwinPorts).
2256
Brett Cannon43802422005-02-10 20:48:03 +00002257- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2258 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2259 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2260 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002262C API
2263-----
2264
Tim Petersc9d78aa2006-03-26 23:27:58 +00002265- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2266 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2267 is obtained via the ``PyObject_`` family, it must be released via the
2268 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2269 always been officially true, but when Python's small-object allocator was
2270 introduced, an attempt was made to cater to a few extension modules
2271 discovered at the time that obtained memory via ``PyObject_New`` but
2272 released it via ``PyMem_DEL``. It's years later, and if such code still
2273 exists it will fail now (probably with segfaults, but calling wrong
2274 low-level memory management functions can yield many symptoms).
2275
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002276- Added a C API for set and frozenset objects.
2277
Raymond Hettinger66517482004-12-03 11:45:13 +00002278- Removed PyRange_New().
2279
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002280- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2281 mapping argument now. This string is used as a mapping table. Byte values
2282 greater than the length of the string and 0xFFFE are treated as undefined
2283 mappings.
