Guido van Rossumc69ac252006-08-10 18:09:25 +000076What's New in Python 2.5 release candidate 1?
77=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +000078
Anthony Baxterb4096662006-08-16 03:42:26 +000079*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +000080
81Core and builtins
82-----------------
83
Marc-André Lemburg040f76b2006-08-14 10:55:19 +000084- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000085 compared equal or unequal to a string and a UnicodeDecodeError
86 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +000087
Marc-André Lemburg040f76b2006-08-14 10:55:19 +000088 Instead, the equal (==) and unequal (!=) comparison operators will
89 now issue a UnicodeWarning and interpret the two objects as
90 unequal. The UnicodeWarning can be filtered as desired using
91 the warning framework, e.g. silenced completely, turned into an
92 exception, logged, etc.
93
94 Note that compare operators other than equal and unequal will still
95 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +000096
Marc-André Lemburg757ea272006-08-14 11:44:34 +000097- Fix segfault when doing string formatting on subclasses of long.
98
99- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
100 with new-style classes.
101
102- Fix bug related to __len__ functions returning negative values with
103 classic classes.
104
105- Patch #1538606, Fix __index__() clipping. There were some problems
106 discovered with the API and how integers that didn't fit into Py_ssize_t
107 were handled. This patch attempts to provide enough alternatives
108 to effectively use __index__.
109
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000110- Bug #1536021: __hash__ may now return long int; the final hash
111 value is obtained by invoking hash on the long int.
112
Thomas Hellerab1049c2006-08-08 17:37:00 +0000113- Bug #1536786: buffer comparison could emit a RuntimeWarning.
114
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000115- Bug #1535165: fixed a segfault in input() and raw_input() when
116 sys.stdin is closed.
117
Thomas Heller74d36f02006-08-04 18:17:40 +0000118- On Windows, the PyErr_Warn function is now exported from
119 the Python dll again.
120
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000121- Bug #1191458: tracing over for loops now produces a line event
122 on each iteration. Fixing this problem required changing the .pyc
123 magic number. This means that .pyc files generated before 2.5c1
124 will be regenerated.
125
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000126- Bug #1333982: string/number constants were inappropriately stored
127 in the byte code and co_consts even if they were not used, ie
128 immediately popped off the stack.
129
Georg Brandle9462c72006-08-04 18:03:37 +0000130- Fixed a reference-counting problem in property().
131
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000132
133Library
134-------
135
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000136- Fix a bug in the ``compiler`` package that caused invalid code to be
137 generated for generator expressions.
138
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000139- The distutils version has been changed to 2.5.0. The change to
140 keep it programmatically in sync with the Python version running
141 the code (introduced in 2.5b3) has been reverted. It will continue
142 to be maintained manually as static string literal.
143
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000144- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000145 and this cannot be converted to the required C type, an exception is
146 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000147 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000148
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000149- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000150 an exception.
151
Tim Petersc10c9d02006-09-05 02:18:09 +0000152- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000153 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000154 workarounds for clocks with low resolution, to stop the code yielding
155 duplicate UUIDs.
156
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000157- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
158 before raising SystemExit, allowing IDLE to honor quit() and exit().
159
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000160- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
161
Georg Brandl7a1af772006-08-14 21:55:28 +0000162- Patch #1536071: trace.py should now find the full module name of a
163 file correctly even on Windows.
164
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000165- logging's atexit hook now runs even if the rest of the module has
166 already been cleaned up.
167
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000168- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000169
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000170- Bug #1531405, format_exception no longer raises an exception if
171 str(exception) raised an exception.
172
Neil Schemenauer06ded092006-08-04 16:20:30 +0000173- Fix a bug in the ``compiler`` package that caused invalid code to be
174 generated for nested functions.

Georg Brandl3335a7a2006-08-14 21:42:55 +0000182- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
183 raises the correct exceptions.
184
Thomas Heller1ce433e2006-08-14 16:20:04 +0000185- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
186 '-no-stack-protector' compiler flag for OpenBSD has been removed.
187
Thomas Heller86720042006-08-14 11:17:48 +0000188- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
189 uses the _as_parameter_ attribute when objects are passed to foreign
190 function calls. The ctypes version number was changed to 1.0.1.
191
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000192- Bug #1530559, struct.pack raises TypeError where it used to convert.
193 Passing float arguments to struct.pack when integers are expected
194 now triggers a DeprecationWarning.

Fred Drake53912162006-07-29 13:22:49 +0000239What's New in Python 2.5 beta 3?
240================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000241
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000242*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000243
244Core and builtins
245-----------------
246
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000247- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000248 returned a long (see PEP 353).
249
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000250- Bug #1515471: string.replace() accepts character buffers again.
251
Neal Norwitz07aadb12006-07-30 06:55:48 +0000252- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
253 This provides the proper warning for struct.pack().
254 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
255
Neal Norwitz0d62a062006-07-30 06:53:31 +0000256- Patch #1531113: Fix augmented assignment with yield expressions.
257 Also fix a SystemError when trying to assign to yield expressions.
258
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000259- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
260 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
261 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
262 excessive filesystem operations during imports.
263
Tim Petersbc24eee2006-07-27 01:14:53 +0000264- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
265 operations on signed longs that are formally undefined by C.
266 Unfortunately, at least one compiler now cares about that, so complicated
267 the code to make that compiler happy again.
268
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000269- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
270
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000271- Patch #1232023: Stop including current directory in search
272 path on Windows.
273
Neal Norwitze1fdb322006-07-21 05:32:28 +0000274- Fix some potential crashes found with failmalloc.
275
Neal Norwitze7563102006-07-17 01:00:16 +0000276- Fix warnings reported by Klocwork's static analysis tool.
277
Neal Norwitz84be93b2006-07-16 01:50:38 +0000278- Bug #1512814, Fix incorrect lineno's when code within a function
279 had more than 255 blank lines.
280
Georg Brandl9dceedb2006-07-12 15:31:17 +0000281- Patch #1521179: Python now accepts the standard options ``--help`` and
282 ``--version`` as well as ``/?`` on Windows.
283
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000284- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000285 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000286 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000287
Tim Peters112aad32006-07-19 00:03:19 +0000288- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000289 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000290 new ``sys._current_frames()`` returns a dictionary with one entry,
291 mapping the faux "thread id" 0 to the current frame.
292
Ronald Oussoren3075e162006-07-25 20:28:55 +0000293- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

298
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000299- Correction of patch #1455898: In the mbcs decoder, set final=False
300 for stream decoder, but final=True for the decode function.
301
Georg Brandl07fec3a2006-08-01 18:49:24 +0000302- os.urandom no longer masks unrelated exceptions like SystemExit or
303 KeyboardInterrupt.
304
Tim Peters4643c2f2006-08-10 22:45:34 +0000305- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000306 shutil.copytree on Windows
307
Georg Brandle34ac7c2006-07-30 11:07:23 +0000308- Bug #1002398: The documentation for os.path.sameopenfile now correctly
309 refers to file descriptors, not file objects.

Tim Petersc10c9d02006-09-05 02:18:09 +0000311- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000312 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000313 #1513611, and probably others.
314
Georg Brandledd9b0d2006-07-29 09:33:26 +0000315- Bug #1441397: The compiler module now recognizes module and function
316 docstrings correctly as it did in Python 2.4.
317
Tim Peters6f681472006-07-27 23:44:37 +0000318- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
319 lost that tests are sorted by name before being run. This rarely
320 matters for well-written tests, but can create baffling symptoms if
321 side effects from one test to the next affect outcomes. ``DocTestFinder``
322 has been changed to sort the list of tests it returns.
323
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000324- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000325 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000326
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000327- Bug #978833: Really close underlying socket in _socketobject.close.
328
Georg Brandl8c036cc2006-08-20 13:15:39 +0000329- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
330 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000331
Georg Brandlcf0c1722006-07-26 07:23:32 +0000332- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
333 to recursive calls and call it with the failing package name.
334
Martin v. Löwis0b483032006-07-25 09:53:12 +0000335- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
336
Georg Brandlc13c34c2006-07-24 14:09:56 +0000337- Patch #1515343: Fix printing of deprecated string exceptions with a
338 value in the traceback module.
339
Greg Ward48fae7a2006-07-23 16:05:51 +0000340- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
341
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000342- Patch #1524429: Use repr() instead of backticks in Tkinter again.
343
Brett Cannoncaebe222006-07-18 04:41:36 +0000344- Bug #1520914: Change time.strftime() to accept a zero for any position in its
345 argument tuple. For arguments where zero is illegal, the value is forced to
346 the minimum value that is correct. This is to support an undocumented but
347 common way people used to fill in inconsequential information in the time
348 tuple pre-2.4.
349
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000350- Patch #1220874: Update the binhex module for Mach-O.
351
Barry Warsawb110bad2006-07-21 14:51:07 +0000352- The email package has improved RFC 2231 support, specifically for
353 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
354 (name*0=<blah>) parameter continuations. This may change the types of
355 values returned from email.message.Message.get_param() and friends.
356 Specifically in some cases where non-encoded continuations were used,
357 get_param() used to return a 3-tuple of (None, None, string) whereas now it
358 will just return the string (since non-encoded continuations don't have
359 charset and language parts).
360
361 Also, whereas % values were decoded in all parameter continuations, they are
362 now only decoded in encoded parameter parts.
363
Ronald Oussoren3075e162006-07-25 20:28:55 +0000364- Bug #1517990: IDLE keybindings on MacOS X now work correctly
365
366- Bug #1517996: IDLE now longer shows the default Tk menu when a
367 path browser, class browser or debugger is the frontmost window on MacOS X
368
Barry Warsaw00decd72006-07-27 23:43:15 +0000369- Patch #1520294: Support for getset and member descriptors in types.py,
370 inspect.py, and pydoc.py. Specifically, this allows for querying the type
371 of an object against these built-in types and more importantly, for getting
372 their docstrings printed in the interactive interpreter's help() function.

376-----------------
377
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000378- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
379 a socket operation on a socket with a timeout, the exception will be
380 caught correctly. Previously, the exception was not caught.
381
Thomas Heller1393d6a2006-07-28 21:43:20 +0000382- Patch #1529514: The _ctypes extension is now compiled on more
383 openbsd target platforms.
384
Tim Peters9cab5932006-07-28 00:30:00 +0000385- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
386 a memory leak, affecting pickles and deep copies.
387
Tim Petersbc24eee2006-07-27 01:14:53 +0000388- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

390
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000391- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
392
Thomas Hellerce049a02006-07-14 17:51:14 +0000393- Patch #1521817: Index range checking on ctypes arrays containing
394 exactly one element enabled again. This allows iterating over these
395 arrays, without the need to check the array size before.
396
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000397- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000398 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000399 /dev/null in certain cases; this is now fixed.
400
Thomas Heller47d7a062006-07-12 08:43:47 +0000401- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
402 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000403
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000404- Because of a misspelled preprocessor symbol, ctypes was always
405 compiled without thread support; this is now fixed.
406
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000407- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
408 methods now allow their database parameter to be None as the
409 sleepycat API allows.
410
Matt Flemingec926502006-07-28 11:27:27 +0000411- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
412 bluetooth API compared with Linux and FreeBSD.
413
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000414Tests
415-----
416
417- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
418 how long the test file should take to play. Now accepts taking 2.93 secs
419 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
420
Georg Brandl4793aa32006-07-28 18:31:39 +0000421- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
422 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
423 run via ``regrtest.py``. Now they do.

429
Ronald Oussoren26cad082006-08-01 21:00:57 +0000430Mac
431---
432
433- PythonLauncher now works correctly when the path to the script contains
434 characters that are treated specially by the shell (such as quotes).
435
436- Bug #1527397: PythonLauncher now launches scripts with the working directory
437 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000438 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000439 expect.

447Core and builtins
448-----------------
449
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000450- Bug #1441486: The literal representation of -(sys.maxint - 1)
451 again evaluates to a int object, not a long.
452
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000453- Bug #1501934: The scope of global variables that are locally assigned
454 using augmented assignment is now correctly determined.
455
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000456- Bug #927248: Recursive method-wrapper objects can now safely
457 be released.
458
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000459- Bug #1417699: Reject locale-specific decimal point in float()
460 and atof().
461
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000462- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
463 omit a default "error" argument for NULL pointer. This allows
464 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000465
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000466- Bug #1519018: 'as' is now validated properly in import statements.
467
Neal Norwitz28746ab2006-07-09 22:14:42 +0000468- On 64 bit systems, int literals that use less than 64 bits are
469 now ints rather than longs.
470
Neal Norwitzed657552006-07-10 00:04:44 +0000471- Bug #1512814, Fix incorrect lineno's when code at module scope
472 started after line 256.
473
Tim Peters32a83612006-07-10 21:08:24 +0000474- New function ``sys._current_frames()`` returns a dict mapping thread
475 id to topmost thread stack frame. This is for expert use, and is
476 especially useful for debugging application deadlocks. The functionality
477 was previously available in Fazal Majid's ``threadframe`` extension
478 module, but it wasn't possible to do this in a wholly threadsafe way from
479 an extension.

496
Thomas Woutersadd19112006-07-05 11:03:49 +0000497- string.Template() now correctly handles tuple-values. Previously,
498 multi-value tuples would raise an exception and single-value tuples would
499 be treated as the value they contain, instead.
500
Martin v. Löwisede77f52006-07-03 13:01:35 +0000501- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

Martin v. Löwis2b88f632006-07-03 10:19:49 +0000511 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000512

514 is created.
515

520 attribute values.
521
522- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
523 sgmllib ('[' and ']' were not accepted).
524
Georg Brandl1be63af2006-06-28 20:23:25 +0000525- Fix a bug in the turtle module's end_fill function.
526
Brett Cannon53ab5b72006-06-22 16:49:14 +0000527- Bug #1510580: The 'warnings' module improperly required that a Warning
528 category be either a types.ClassType and a subclass of Warning. The proper
529 check is just that it is a subclass with Warning as the documentation states.
530
Georg Brandlad29e632006-06-21 17:45:17 +0000531- The compiler module now correctly compiles the new try-except-finally
532 statement (bug #1509132).
533
Neal Norwitz60373cd2006-06-22 06:30:50 +0000534- The wsgiref package is now installed properly on Unix.
535
Vinay Sajip28e57612006-07-01 10:45:20 +0000536- A bug was fixed in logging.config.fileConfig() which caused a crash on
537 shutdown when fileConfig() was called multiple times.
538
Gerhard Häring762fbd32006-07-02 17:48:30 +0000539- The sqlite3 module did cut off data from the SQLite database at the first
540 null character before sending it to a custom converter. This has been fixed
541 now.

544-----------------
545
Tim Peters112aad32006-07-19 00:03:19 +0000546- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
547 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
548 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000549
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000550- Assigning None to pointer type fields in ctypes structures possible
551 overwrote the wrong fields, this is fixed now.
552
553- Fixed a segfault in _ctypes when ctypes.wintypes were imported
554 on non-Windows platforms.
555
556- Bug #1518190: The ctypes.c_void_p constructor now accepts any
557 integer or long, without range checking.
558
559- Patch #1517790: It is now possible to use custom objects in the ctypes
560 foreign function argtypes sequence as long as they provide a from_param
561 method, no longer is it required that the object is a ctypes type.
562
563- The '_ctypes' extension module now works when Python is configured
564 with the --without-threads option.
565
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000566- Bug #1513646: os.access on Windows now correctly determines write

581
Tim Peters32a83612006-07-10 21:08:24 +0000582- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000583 Previously, the slight difference could cause compilation errors of the
584 'zlib' module on systems with more than one version of zlib.
585
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000586- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxterd1136802006-06-19 12:04:15 +0000615*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000616
617Core and builtins
618-----------------
619
Georg Brandla56b9152006-06-19 06:35:54 +0000620- Patch #1507676: Error messages returned by invalid abstract object operations
621 (such as iterating over an integer) have been improved and now include the
622 type of the offending object to help with debugging.
623
Brett Cannonea3912b2006-06-13 21:46:41 +0000624- Bug #992017: A classic class that defined a __coerce__() method that returned
625 its arguments swapped would infinitely recurse and segfault the interpreter.
626
Neal Norwitz909eb122006-06-12 02:13:21 +0000627- Fix the socket tests so they can be run concurrently.
628
Neal Norwitzb9845e72006-06-12 02:11:18 +0000629- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000630 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000631
Brett Cannon22565aa2006-06-09 22:31:23 +0000632- Bug #532646: object.__call__() will continue looking for the __call__
633 attribute on objects until one without one is found. This leads to recursion
634 when you take a class and set its __call__ attribute to an instance of the
635 class. Originally fixed for classic classes, but this fix is for new-style.
636 Removes the infinite_rec_3 crasher.
637
Georg Brandl24250812006-06-09 18:45:48 +0000638- The string and unicode methods startswith() and endswith() now accept
639 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
640
Brett Cannonde3b0522006-06-08 17:00:45 +0000641- Buffer objects, at the C level, never used the char buffer
642 implementation even when the char buffer for the wrapped object was
643 explicitly requested (originally returned the read or write buffer).
644 Now a TypeError is raised if the char buffer is not present but is
645 requested.
646
Georg Brandlddbaa662006-06-04 21:56:52 +0000647- Patch #1346214: Statements like "if 0: suite" are now again optimized
648 away like they were in Python 2.4.
649
Georg Brandlb7c8f542006-05-27 12:30:25 +0000650- Builtin exceptions are now full-blown new-style classes instead of
651 instances pretending to be classes, which speeds up exception handling
652 by about 80% in comparison to 2.5a2.
653
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000654- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
655 Unicode 4.1.
656
Georg Brandlf4ef1162006-05-26 18:03:31 +0000657- Patch #921466: sys.path_importer_cache is now used to cache valid and
658 invalid file paths for the built-in import machinery which leads to
659 fewer open calls on startup.
660
Tim Peters696cf432006-05-24 21:10:40 +0000661- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
662 of-2 bases. The largest speedup is for inputs with about 1000 decimal
663 digits. Conversion from non-power-of-2 bases remains quadratic-time in
664 the number of input digits (it was and remains linear-time for bases
665 2, 4, 8, 16 and 32).
666
Tim Petersb713ec22006-05-23 18:45:30 +0000667- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
668 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
669 an integer close to ``sys.maxint``. This was repaired by patch
670 #1335972, which also gives a nice speedup.
671
Richard Jonescebbefc2006-05-23 18:28:17 +0000672- Patch #1337051: reduced size of frame objects.
673
674- PyErr_NewException now accepts a tuple of base classes as its
675 "base" parameter.
676
Richard Jones7c88dcc2006-05-23 10:37:38 +0000677- Patch #876206: function call speedup by retaining allocated frame
678 objects.
679
Georg Brandl7b90e162006-05-18 07:01:27 +0000680- Bug #1462152: file() now checks more thoroughly for invalid mode
681 strings and removes a possible "U" before passing the mode to the
682 C library function.
683
Neal Norwitz1004a532006-05-15 07:17:23 +0000684- Patch #1488312, Fix memory alignment problem on SPARC in unicode
685
Neal Norwitz373f0a72006-05-15 07:04:36 +0000686- Bug #1487966: Fix SystemError with conditional expression in assignment
687
Martin v. Löwis879768d2006-05-11 13:28:43 +0000688- WindowsError now has two error code attributes: errno, which carries
689 the error values from errno.h, and winerror, which carries the error
690 values from winerror.h. Previous versions put the winerror.h values
691 (from GetLastError()) into the errno attribute.
692
Martin v. Löwis77736712006-05-04 05:51:03 +0000693- Patch #1475845: Raise IndentationError for unexpected indent.
694
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000695- Patch #1479181: split open() and file() from being aliases for each other.
696
Tim Peters44bd9862006-06-01 13:49:23 +0000697- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
698 methods were always silently ignored by dictionaries when comparing keys.
699 They are now passed through (except when using the C API function
700 ``PyDict_GetItem()``, whose semantics did not change).
701
702- Bug #1456209: In some obscure cases it was possible for a class with a
703 custom ``__eq__()`` method to confuse dict internals when class instances
704 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
705 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000707Extension Modules
708-----------------
709
Trent Mick960a3f82006-06-28 20:30:41 +0000710- Bug #1295808: expat symbols should be namespaced in pyexpat
711
712- Patch #1462338: Upgrade pyexpat to expat 2.0.0
713
Brett Cannon6ee7d012006-06-08 16:23:04 +0000714- Change binascii.hexlify to accept a read-only buffer instead of only a char
715 buffer and actually follow its documentation.
716
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000717- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
718
Nick Coghlanc649ec52006-05-29 12:43:05 +0000719- Patch #1478788 (modified version): The functional extension module has
720 been renamed to _functools and a functools Python wrapper module added.
721 This provides a home for additional function related utilities that are
722 not specifically about functional programming. See PEP 309.
723
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000724- Patch #1493701: performance enhancements for struct module.
725
Georg Brandl378d5922006-05-17 14:26:50 +0000726- Patch #1490224: time.altzone is now set correctly on Cygwin.
727
Georg Brandl8d3342b2006-05-16 07:38:27 +0000728- Patch #1435422: zlib's compress and decompress objects now have a
729 copy() method.
730
Andrew MacIntyre92913322006-06-13 15:04:24 +0000731- Patch #1454481: thread stack size is now tunable at runtime for thread
732 enabled builds on Windows and systems with Posix threads support.
733
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000734- On Win32, os.listdir now supports arbitrarily-long Unicode path names
735 (up to the system limit of 32K characters).
736
737- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
738 As a result, these functions now raise WindowsError instead of OSError.
739
Tim Peters7a822da2006-05-25 21:50:17 +0000740- ``time.clock()`` on Win64 should use the high-performance Windows
741 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
742 Windows platforms).
743
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000744- Calling Tk_Init twice is refused if the first call failed as that
745 may deadlock.
746
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000747- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
748 accept it without potentially using an uninitialized pointer.
749
750- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
751 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
752 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000753
Gregory P. Smith372b5832006-06-05 18:48:21 +0000754- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000755 [pybsddb project SF patch number 1466734]
756
Gregory P. Smith372b5832006-06-05 18:48:21 +0000757- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
758 parameter is supplied. [SF pybsddb bug #1477863]
759
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000760- bsddb: the __len__ method of a DB object has been fixed to return correct
761 results. It could previously incorrectly return 0 in some cases.
762 Fixes SF bug 1493322 (pybsddb bug 1184012).
763
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000764- bsddb: the bsddb.dbtables Modify method now raises the proper error and
765 aborts the db transaction safely when a modifier callback fails.
766 Fixes SF python patch/bug #1408584.
767
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000768- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000769 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000770 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
771 database calls that would previously deadlock. [SF python bug #775414]
772
Vinay Sajip28e57612006-07-01 10:45:20 +0000773- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000774
Walter Dörwald4994d952006-06-19 08:07:50 +0000775- Patch #1506645: add Python wrappers for the curses functions
776 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000777

780
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000781- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
782 functions.
783
Martin v. Löwis3798da02006-06-17 18:44:27 +0000784- Patch #812986: Update turtle output even if not tracing.
785
Vinay Sajip28e57612006-07-01 10:45:20 +0000786- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000787 Tkinter.BaseWidget.
788
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000789- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
790
Martin v. Löwis337487e2006-06-17 09:15:14 +0000791- Patch #763580: Add name and value arguments to Tkinter variable
792 classes.
793
Georg Brandl83cc0d02006-06-14 08:50:03 +0000794- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
795 mime.types file for determining MIME types.
796
Georg Brandl2605ca82006-06-14 06:08:31 +0000797- Bug #1339007: Shelf objects now don't raise an exception in their
798 __del__ method when initialization failed.
799
Martin v. Löwisd8251432006-06-14 05:21:04 +0000800- Patch #1455898: The MBCS codec now supports the incremental mode for
801 double-byte encodings.
802
Tim Peters43898b42006-06-14 04:09:25 +0000803- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
804 guarantee that adjacent triples in the return list always describe
805 non-adjacent blocks. Previously, a pair of matching blocks could end
806 up being described by multiple adjacent triples that formed a partition
807 of the matching pair.
808
Greg Ward0e0c9f42006-06-11 16:24:11 +0000809- Bug #1498146: fix optparse to handle Unicode strings in option help,
810 description, and epilog.
811
Greg Wardd1c797e2006-06-11 14:42:41 +0000812- Bug #1366250: minor optparse documentation error.
813
Greg Ward7f547402006-06-11 00:40:49 +0000814- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
815 clarify docs.
816
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000817- The wsgiref package has been added to the standard library.
818
Nick Coghlan676725d2006-06-08 13:54:49 +0000819- The functions update_wrapper() and wraps() have been added to the functools
820 module. These make it easier to copy relevant metadata from the original
821 function when writing wrapper functions.
822
Tim Petersd6a9eef2006-06-05 01:48:21 +0000823- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
824 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000825
Martin v. Löwis3f767792006-06-04 19:36:28 +0000826- Patch #1359618: Speed up charmap encoder by using a trie structure
827 for lookup.
828
Tim Petersd609b1a2006-06-02 23:22:51 +0000829- The functions in the ``pprint`` module now sort dictionaries by key
830 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
831 if and only if its display required more than one line, although that
832 wasn't documented. The new behavior increases predictability; e.g.,
833 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
834
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000835- Patch #1497027: try HTTP digest auth before basic auth in urllib2
836 (thanks for J. J. Lee).
837
Georg Brandl2b330372006-05-28 20:23:12 +0000838- Patch #1496206: improve urllib2 handling of passwords with respect to
839 default HTTP and HTTPS ports.
840
George Yoshidaf3c65de2006-05-28 16:39:09 +0000841- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
842
Bob Ippolito7298f272006-05-23 18:43:47 +0000843- Patch #1281707: speed up gzip.readline.
844
Georg Brandlb89316f2006-05-17 15:51:16 +0000845- Patch #1180296: Two new functions were added to the locale module:
846 format_string() to get the effect of "format % items" but locale-aware,
847 and currency() to format a monetary number with currency sign.
848
Georg Brandle3a25832006-05-17 14:56:04 +0000849- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
850 and several features added, such as speed and geometry control.
851
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000852- Patch #1488881: add support for external file objects in bz2 compressed
853 tarfiles.
854
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000855- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
856 stdout arguments, making it possible to redirect input and output
857 for remote debugging.
858
859- Patch #1484695: Update the tarfile module to version 0.8. This fixes
860 a couple of issues, notably handling of long file names using the
861 GNU LONGNAME extension.
862
863- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
864 new flag when ``name`` is already the name of an option flag.
865
866- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
867 package.
868
869- Patch #1472854: make the rlcompleter.Completer class usable on non-
870 UNIX platforms.
871
872- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
873
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000874- Bug #1472827: correctly escape newlines and tabs in attribute values in
875 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000905What's New in Python 2.5 alpha 2?
906=================================
907
908*Release date: 27-APR-2006*
909
910Core and builtins
911-----------------
912
Thomas Heller1b046642006-04-18 18:51:06 +0000913- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
914 by converting these apis from macros into exported functions again:
915
916 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
917 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
918 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
919 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
920 PyRun_String Py_CompileString
921
Martin v. Löwis45294a92006-04-18 06:24:08 +0000922- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
923
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000924- All uses of PyStructSequence_InitType have been changed to initialize
925 the type objects only once, even if the interpreter is initialized
926 multiple times.
927
Neal Norwitz61546162006-04-14 05:20:28 +0000928- Bug #1454485, array.array('u') could crash the interpreter. This was
929 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
930 to unicode when it didn't make sense. 'u#' now requires a unicode string.
931
932- Py_UNICODE is unsigned. It was always documented as unsigned, but
933 due to a bug had a signed value in previous versions.
934
Tim Peters3a5e8b12006-04-11 01:44:07 +0000935- Patch #837242: ``id()`` of any Python object always gives a positive
936 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
937 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000938 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000939 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000940
Tim Peters3a5e8b12006-04-11 01:44:07 +0000941 def __hash__(self):
942 return id(self) # WRONG
943
944 because a hash result must be a (short) Python int but it was always
945 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000946 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000947 was always usable as a hash value before this patch. That's no longer
948 necessarily so.
949
950- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000951 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000952 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000953 #1454844)
954
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000955- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
956 involving generators that have paused outside of any ``try`` or ``with``
957 blocks. (In 2.5a1, a paused generator that was part of a reference
958 cycle could not be garbage collected, regardless of whether it was
959 paused in a ``try`` or ``with`` block.)

976 a temporary db (file=None) with the 'n' flag to truncate on open.
977
978- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
979 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000980
Armin Rigoa9017c32006-04-19 11:50:27 +0000981- Patch #1062014: AF_UNIX sockets under Linux have a special
982 abstract namespace that is now fully supported.

985-------
986
Peter Astrand7d1d4362006-07-14 14:04:45 +0000987- Bug #1223937: subprocess.CalledProcessError reports the exit status
988 of the process using the returncode attribute, instead of
989 abusing errno.
990
Tim Peters711bf302006-04-25 03:31:36 +0000991- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
992 a doctest to be skipped (the code is not run, and the expected output
993 or exception is ignored).
994
Nick Coghlanda2268f2006-04-24 04:37:15 +0000995- Fixed contextlib.nested to cope with exceptions being raised and
996 caught inside exit handlers.
997
Greg Wardab05edc2006-04-23 03:47:58 +0000998- Updated optparse module to Optik 1.5.1 (allow numeric constants in
999 hex, octal, or binary; add ``append_const`` action; keep going if
1000 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1001 added ``epilog`` for better help generation).
1002
Tim Peters21fbd572006-04-21 21:18:10 +00001003- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1004 called from a thread spawned as a side effect of importing a module.
1005
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001006- The pydoc module now supports documenting packages contained in
1007 .zip or .egg files.
1008
1009- The pkgutil module now has several new utility functions, such
1010 as ``walk_packages()`` to support working with packages that are either
1011 in the filesystem or zip files.
1012
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001013- The mailbox module can now modify and delete messages from
1014 mailboxes, in addition to simply reading them. Thanks to Gregory
1015 K. Johnson for writing the code, and to the 2005 Google Summer of
1016 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001017
Tim Petersc7605f22006-04-17 21:12:33 +00001018- The ``__del__`` method of class ``local`` in module ``_threading_local``

1029
Phillip J. Eby47032112006-04-11 01:07:43 +00001030- The warnings, linecache, inspect, traceback, site, and doctest modules
1031 were updated to work correctly with modules imported from zipfiles or
1032 via other PEP 302 __loader__ objects.

1040
Skip Montanaro262fb922006-04-21 02:31:07 +00001041- The pstats.Stats class accepts an optional stream keyword argument to
1042 direct output to an alternate file-like object.
1043
Anthony Baxter51bcb682006-04-05 14:51:42 +00001044Build
1045-----
1046
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001047- The Makefile now has a reindent target, which runs reindent.py on
1048 the library.
1049
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001050- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001053
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001054- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1055 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001056 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001057 CXX from --with-cxx-main, see description in README.
1058
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001059- Patch #1429775: Link extension modules with the shared libpython.
1060
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001061- Fixed a libffi build problem on MIPS systems.
1062
Tim Peters8931ff12006-05-13 23:28:20 +00001063- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1064 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1065 and "%zu" for unsigned integers of type ``size_t``.
1066
Anthony Baxter51bcb682006-04-05 14:51:42 +00001067Tests
1068-----
1069
Nick Coghlanda2268f2006-04-24 04:37:15 +00001070- test_contextlib now checks contextlib.nested can cope with exceptions
1071 being raised and caught inside exit handlers.
1072
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001073- test_cmd_line now checks operation of the -m and -c command switches
1074
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001075- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1076 it separately and by hand. It also wasn't cleaning up its changes to
1077 the current Decimal context.
1078
Thomas Woutersabd08882006-04-26 15:53:30 +00001079- regrtest.py now has a -M option to run tests that test the new limits of
1080 containers, on 64-bit architectures. Running these tests is only sensible
1081 on 64-bit machines with more than two gigabytes of memory. The argument
1082 passed is the maximum amount of memory for the tests to use.

1091-------------
1092
Tim Petersb06d28c2006-05-12 01:57:59 +00001093- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1094
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001095- PEP 343: Added Context Types section to the library reference
1096 and attempted to bring other PEP 343 related documentation into
1097 line with the implementation and/or python-dev discussions.
1098
Tim Peters8dc73d22006-04-24 02:03:16 +00001099- Bug #1337990: clarified that ``doctest`` does not support examples
1100 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001103What's New in Python 2.5 alpha 1?
1104=================================
1105
Anthony Baxterebed3f62006-04-03 15:03:44 +00001106*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001107
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001108Core and builtins
1109-----------------
1110
Nick Coghlan43832302006-04-23 17:04:07 +00001111- PEP 338: -m command line switch now delegates to runpy.run_module
1112 allowing it to support modules in packages and zipfiles
1113
Martin v. Löwisc661b882006-04-20 04:54:23 +00001114- On Windows, .DLL is not an accepted file name extension for
1115 extension modules anymore; extensions are only found if they
1116 end in .PYD.
1117
Martin v. Löwisea62d252006-04-03 10:56:49 +00001118- Bug #1421664: sys.stderr.encoding is now set to the same value as
1119 sys.stdout.encoding.
1120
Neal Norwitz92e212f2006-04-03 04:48:37 +00001121- __import__ accepts keyword arguments.
1122
Georg Brandlccadf842006-03-31 18:54:53 +00001123- Patch #1460496: round() now accepts keyword arguments.
1124
Anthony Baxter262c00a2006-03-30 10:53:17 +00001125- Fixed bug #1459029 - unicode reprs were double-escaped.
1126
Hye-Shik Changd478f342006-03-23 12:32:36 +00001127- Patch #1396919: The system scope threads are reenabled on FreeBSD
1128 5.4 and later versions.
1129
Neal Norwitze98ccf62006-03-23 05:39:47 +00001130- Bug #1115379: Compiling a Unicode string with an encoding declaration
1131 now gives a SyntaxError.
1132
Georg Brandlabd1ff82006-03-18 07:59:59 +00001133- Previously, Python code had no easy way to access the contents of a
1134 cell object. Now, a ``cell_contents`` attribute has been added
1135 (closes patch #1170323).
1136
Tim Peterscf79aac2006-03-16 01:14:46 +00001137- Patch #1123430: Python's small-object allocator now returns an arena to
1138 the system ``free()`` when all memory within an arena becomes unused
1139 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1140 freed. Some applications will see a drop in virtual memory size now,
1141 especially long-running applications that, from time to time, temporarily
1142 use a large number of small objects. Note that when Python returns an
1143 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001144 platform C library will in turn return that memory to the operating system.
1145 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001146 appears to be effective at least on Microsoft C and gcc-based systems.
1147 Thanks to Evan Jones for hard work and patience.
1148
Georg Brandl533ff6f2006-03-08 18:09:27 +00001149- Patch #1434038: property() now uses the getter's docstring if there is
1150 no "doc" argument given. This makes it possible to legitimately use
1151 property() as a decorator to produce a read-only property.
1152
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001153- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1154 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1155 of requiring an int or long in slicing and a few other contexts, enabling
1156 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1157
Neal Norwitz995acdf2006-03-07 05:01:00 +00001158- Fixed various bugs reported by Coverity's Prevent tool.
1159
Brett Cannonbf364092006-03-01 04:25:17 +00001160- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1161 new exception base class, BaseException, which has a new message attribute.
1162 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1163 Raising a string exception now raises a DeprecationWarning.
1164
Thomas Woutersfb609f42006-02-28 16:37:25 +00001165- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1166 explicitly relative, using 'from .module import name' to mean 'from the same
1167 package as this module is in. Imports without dots still default to the
1168 old relative-then-absolute, unless 'from __future__ import
1169 absolute_import' is used.
1170
Brett Cannona7446e32006-02-27 23:39:10 +00001171- Properly check if 'warnings' raises an exception (usually when a filter set
1172 to "error" is triggered) when raising a warning for raising string
1173 exceptions.
1174
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001175- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001176 The name was removed from Include/code.h.
1177
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001178- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001179
Guido van Rossum1968ad32006-02-25 22:38:04 +00001180- Patch 1433928:
1181 - The copy module now "copies" function objects (as atomic objects).
1182 - dict.__getitem__ now looks for a __missing__ hook before raising
1183 KeyError.
1184
Tim Peters84ef21c2006-02-28 20:39:06 +00001185- PEP 343: with statement implemented. Needs ``from __future__ import
1186 with_statement``. Use of 'with' as a variable will generate a warning.
1187 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001188 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001189 The following objects have __context__ methods:
1190 - The built-in file type.
1191 - The thread.LockType type.
1192 - The following types defined by the threading module:
1193 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1194 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001195
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001196- Fix the encodings package codec search function to only search
1197 inside its own package. Fixes problem reported in patch #1433198.
1198
1199 Note: Codec packages should implement and register their own
1200 codec search function. PEP 100 has the details.
1201
Tim Peters9ea89d22006-06-04 03:26:02 +00001202- PEP 353: Using ``Py_ssize_t`` as the index type.
1203
1204- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1205 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1206 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1207 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1208 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001209
Neal Norwitzfc76d632006-01-10 06:03:13 +00001210- Patch #1400181, fix unicode string formatting to not use the locale.
1211 This is how string objects work. u'%f' could use , instead of .
1212 for the decimal point. Now both strings and unicode always use periods.
1213
Neal Norwitz671b9e32006-01-09 07:07:12 +00001214- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1215 configure would break checking curses.h.
1216
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001217- Bug #959576: The pwd module is now builtin. This allows Python to be
1218 built on UNIX platforms without $HOME set.
1219
Neal Norwitzc10978f2005-12-19 06:07:16 +00001220- Bug #1072182, fix some potential problems if characters are signed.
1221
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001222- Bug #889500, fix line number on SyntaxWarning for global declarations.
1223
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001224- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1225
Neal Norwitze7214a12005-12-18 05:03:17 +00001226- Support for converting hex strings to floats no longer works.
1227 This was not portable. float('0x3') now raises a ValueError.
1228
Barry Warsaw2a38a862005-12-18 01:27:35 +00001229- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001230 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001231 is now displayed in interactive prompt banner.
1232
Georg Brandlfa166682005-12-17 21:45:17 +00001233- Implementation of PEP 341 - Unification of try/except and try/finally.
1234 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001235 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001236
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001237- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1238 now encodes backslash correctly.
1239
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001240- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1241
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001242- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001243 and long longs.
1244
Neal Norwitz67715f02005-11-09 06:59:35 +00001245- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001246 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001247 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001248
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001249- Replaced most Unicode charmap codecs with new ones using the
1250 new Unicode translate string feature in the builtin charmap
1251 codec; the codecs were created from the mapping tables available
1252 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1253 encodings now include a mapping for the Apple logo)
1254
Tim Peterse3547fd2005-12-16 23:13:57 +00001255- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001256
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001257- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001258
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001259- A new AST parser implementation was completed. The abstract
1260 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001261 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001262
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001263- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001264 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1265
Neal Norwitz708e51a2005-10-03 04:48:15 +00001266- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1267
Neal Norwitz11bd1192005-10-03 00:54:56 +00001268- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1269 Provide a warning when a directory is passed on the command line.
1270
Neal Norwitz40d37812005-10-02 01:48:49 +00001271- Fix segfault with invalid coding.
1272
1273- SF bug #772896: unknown encoding results in MemoryError.
1274
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001275- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001276 supported a __len__() method which evaluated to False when the iterator
1277 was empty.
1278
Guido van Rossum630db602005-09-20 18:49:54 +00001279- On 64-bit platforms, when __len__() returns a value that cannot be
1280 represented as a C int, raise OverflowError.
1281
Skip Montanarof8948ca2005-09-19 03:54:46 +00001282- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001283 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001284
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001285- SF bug #893549: parsing keyword arguments was broken with a few format
1286 codes.
1287
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001288- Changes donated by Elemental Security to make it work on AIX 5.3
1289 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1290 bug #105470: test_pwd fails on 64bit system (Opteron).
1291
Guido van Rossum539c6622005-09-14 17:49:54 +00001292- Changes donated by Elemental Security to make it work on HP-UX 11 on
1293 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1294
Georg Brandl4550b8d2005-08-26 06:43:52 +00001295- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001296 (fixes bug #1119418).
1297
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001298- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1299
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001300- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1301 exceptions that cause a function to exit.
1302
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001303- The implementation of set() and frozenset() was revised to use its
1304 own internal data structure. Memory consumption is reduced by 1/3
1305 and there are modest speed-ups as well. The API is unchanged.
1306
Tim Petersde7990b2005-07-17 23:45:23 +00001307- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1308
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001309- SF bug #1229429: PyObject_CallMethod failed to decrement some
1310 reference counts in some error exit cases.
1311
Tim Petersecc6e6a2005-07-10 22:30:55 +00001312- SF bug #1185883: Python's small-object memory allocator took over
1313 a block managed by the platform C library whenever a realloc specified
1314 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001315 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001316 portable way to copy data from the C-managed block into Python's
1317 small-object space without risking a memory fault. Python's small-object
1318 realloc now leaves such blocks under the control of the platform C
1319 realloc.
1320
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001321- SF bug #1232517: An overflow error was not detected properly when
1322 attempting to convert a large float to an int in os.utime().
1323
Raymond Hettinger3296e692005-06-29 23:29:56 +00001324- SF bug #1224347: hex longs now print with lowercase letters just
1325 like their int counterparts.
1326
Michael W. Hudson188d4362005-06-20 16:52:57 +00001327- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1328 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1329 interpreter states; back out that fix and do a better job (see
1330 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1331 for a longer write-up of the problem).
1332
Michael W. Hudsondf888462005-06-03 14:41:55 +00001333- SF patch #1180995: marshal now uses a binary format by default when
1334 serializing floats.
1335
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001336- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1337 the routines that promise to produce IEEE 754 binary representations
1338 of floats now simply copy bytes around.
1339
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001340- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1341 278.
1342
Brett Cannonc3647ac2005-04-26 03:45:26 +00001343- patch #1109424: int, long, float, complex, and unicode now check for the
1344 proper magic slot for type conversions when subclassed. Previously the
1345 magic slot was ignored during conversion. Semantics now match the way
1346 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001347 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001348 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001349 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001350
Barry Warsawc8d907c2005-04-19 23:43:40 +00001351- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1352 NULL, now raise an AttributeError when attempting to set or delete the
1353 attribute. Previously a TypeError was raised, but this was inconsistent
1354 with the equivalent pure-Python implementation.
1355
Michael W. Hudson774479c2005-04-18 08:46:17 +00001356- It is now safe to call PyGILState_Release() before
1357 PyEval_InitThreads() (note that if there is reason to believe there
1358 are multiple threads around you still must call PyEval_InitThreads()
1359 before using the Python API; this fix is for extension modules that
1360 have no way of knowing if Python is multi-threaded yet).
1361
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001362- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1363 disabled caused a crash.
1364
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001365- Bug #1165306: instancemethod_new allowed the creation of a method
1366 with im_class == im_self == NULL, which caused a crash when called.
1367
Tim Petersecc6e6a2005-07-10 22:30:55 +00001368- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001369 fixes the crash seen in bug #1165761
1370
Raymond Hettinger96229b12005-03-11 06:49:40 +00001371- Added two new builtins, any() and all().
1372
Brett Cannon409d8f22005-03-05 06:47:57 +00001373- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001374 (e.g., ``class C(): pass`` is no longer a syntax error).
1375 Patch #1176012 added support to the 'parser' module and 'compiler' package
1376 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001377
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001378- Patch #1115086: Support PY_LONGLONG in structmember.
1379
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001380- Bug #1155938: new style classes did not check that __init__() was
1381 returning None.
1382
Tim Petersecc6e6a2005-07-10 22:30:55 +00001383- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001384 ('\') with a specific error message.
1385
Martin v. Löwisff232d72005-03-03 09:24:38 +00001386- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1387
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001388- Bug #1124295: the __name__ attribute of file objects was
1389 inadvertently made inaccessible in restricted mode.
1390
Tim Petersecc6e6a2005-07-10 22:30:55 +00001391- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001392 an ferror() call.
1393
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001394- min() and max() now support key= arguments with the same meaning as in
1395 list.sort().
1396
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001397- The peephole optimizer now performs simple constant folding in expressions:
1398 (2+3) --> (5).
1399
Raymond Hettingera422c342005-01-11 03:03:27 +00001400- set and frozenset objects can now be marshalled. SF #1098985.
1401
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001402- Bug #1077106: Poor argument checking could cause memory corruption
1403 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001404
Jeremy Hyltonab630502005-02-04 18:44:06 +00001405- The parser did not complain about future statements in illegal
1406 positions. It once again reports a syntax error if a future
1407 statement occurs after anything other than a doc string.
1408
Neil Schemenauercf52c072005-08-12 17:34:58 +00001409- Change the %s format specifier for str objects so that it returns a
1410 unicode instance if the argument is not an instance of basestring and
1411 calling __str__ on the argument returns a unicode instance.
1412
Tim Petersf4e69282006-02-27 17:15:31 +00001413- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1414 current thread state when the auto-GIL-state machinery knows about
1415 it (since the thread state is being deleted, continuing to remember it
1416 can't help, but can hurt if another thread happens to get created with
1417 the same thread id).
1418
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001419Extension Modules
1420-----------------
1421
Georg Brandl43f08a82006-03-31 18:01:16 +00001422- Patch #1380952: fix SSL objects timing out on consecutive read()s
1423
Neal Norwitz05a45592006-03-20 06:30:08 +00001424- Patch #1309579: wait3 and wait4 were added to the posix module.
1425
Anthony Baxterfa869072006-03-20 05:21:58 +00001426- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1427 In addition, the existing ulaw code was updated.
1428
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001429- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001430 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001431
Neal Norwitz10be10c2006-03-16 06:50:13 +00001432- Everything under lib-old was removed. This includes the following modules:
1433 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001434 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001435 util, whatsound, whrandom, zmod
1436
1437- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1438
1439- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001440 is deprecated. The undocumented re.engine variable no longer exists.
1441
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001442- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1443 SS2 (single-shift 2) escape sequences correctly.
1444
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001445- The unicodedata module was updated to the 4.1 version of the Unicode
1446 database. The 3.2 version is still available as unicodedata.db_3_2_0
1447 for applications that require this specific version (such as IDNA).
1448
Neal Norwitzb62c4332006-03-04 18:35:47 +00001449- The timing module is no longer built by default. It was deprecated
1450 in PEP 4 in Python 2.0 or earlier.
1451
Guido van Rossum1968ad32006-02-25 22:38:04 +00001452- Patch 1433928: Added a new type, defaultdict, to the collections module.
1453 This uses the new __missing__ hook behavior added to dict (see above).
1454
Georg Brandldbd83392006-02-20 09:42:33 +00001455- Bug #854823: socketmodule now builds on Sun platforms even when
1456 INET_ADDRSTRLEN is not defined.
1457
Georg Brandlf4f44152006-02-18 22:29:33 +00001458- Patch #1393157: os.startfile() now has an optional argument to specify
1459 a "command verb" to invoke on the file.
1460
Neal Norwitz082b2df2006-02-07 07:04:46 +00001461- Bug #876637, prevent stack corruption when socket descriptor
1462 is larger than FD_SETSIZE.
1463
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001464- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1465 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1466 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1467
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001468- Patch #1422385: The nis module now supports access to domains other
1469 than the system default domain.
1470
Martin v. Löwis14694662006-02-03 12:54:16 +00001471- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1472 are reported, the limit on path name lengths is removed, and stat reports
1473 WindowsError now (instead of OSError).
1474
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001475- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
1476
Neal Norwitz62a21122006-01-25 05:21:55 +00001477- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
1478 before the env.
1479

1611 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001612
Nick Coghlan43832302006-04-23 17:04:07 +00001613- PEP 338: new module runpy defines a run_module function to support
1614 executing modules which provide access to source code or a code object
1615 via the PEP 302 import mechanisms.
1616

1625 in attribute values.
1626
Anthony Baxterc51ee692006-04-01 00:57:31 +00001627- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001628 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001629 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001630 module will not be built.
1631
Tim Petersc17976e2006-04-01 00:26:53 +00001632- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1633 aren't officially supported here, and trying to use them will probably
1634 raise an exception some day. But dicts have been allowed, and "mostly
1635 worked", so support for them won't go away without warning.
1636
Georg Brandl338ef7d2006-03-31 18:42:16 +00001637- Bug #1445068: getpass.getpass() can now be given an explicit stream

1655
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001656- email 4.0 package now integrated. This is largely the same as the email 3.0
1657 package that was included in Python 2.3, except that PEP 8 module names are
1658 now used (e.g. mail.message instead of email.Message). The MIME classes
1659 have been moved to a subpackage (e.g. email.mime.text instead of
1660 email.MIMEText). The old names are still supported for now. Several
1661 deprecated Message methods have been removed and lots of bugs have been
1662 fixed. More details can be found in the email package documentation.
1663
Walter Dörwald40108c92006-03-27 08:15:44 +00001664- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1665 (a subclass of tuple) that provides incremental decoders and encoders
1666 (a way to use stateful codecs without the stream API). Python functions
1667 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1668 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1669 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001671- Patch #1359365: Calling next() on a closed StringIO.String object raises
1672 a ValueError instead of a StopIteration now (like file and cString.String do).
1673 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1674 called before (like file and StringIO.StringIO do).

Neal Norwitz338e7862005-12-23 21:27:46 +00001743- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
1744 LoadError as documented, instead of IOError. For compatibility,
1745 LoadError subclasses IOError.
1746
Brett Cannon3cbd0382005-12-16 22:49:23 +00001747- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001748 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1749 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1750 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1751 Ronald L. Rivest offered this advice for Python:
1752
1753 "The consensus of researchers in this area (at least as
1754 expressed at the NIST Hash Function Workshop 10/31/05),
1755 is that SHA-256 is a good choice for the time being, but
1756 that research should continue, and other alternatives may
1757 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001758
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001759- Added a subset of Fredrik Lundh's ElementTree package. Available

1801
Georg Brandl532efab2005-08-24 22:34:21 +00001802- Patch #848017: Make Cookie more RFC-compliant. Use CRLF as default output
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001803 separator and do not output trailing semicolon.
Georg Brandl532efab2005-08-24 22:34:21 +00001804
Georg Brandlb9256022005-08-24 18:46:39 +00001805- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
1806 ContentTooShortException, when the actually downloaded size does not
1807 match the Content-Length header.
1808

1812 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001813 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001814

1830 parameter, but uses the usual "kwargs=None".
1831
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001832- textwrap now processes text chunks at O(n) speed instead of O(n**2).

1836 to W3C name (404 -> 'Not Found'). RFE #1216944.
1837
Georg Brandl9e43acf2005-07-04 17:16:07 +00001838- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1839 as this can cause problems with apps closing all file descriptors.

1852 Bug #1224621.
1853
Raymond Hettinger68c04532005-06-10 11:05:19 +00001854- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001855 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001856 the generate_tokens() function now accepts a callable argument that
1857 terminates by raising StopIteration.
1858
Georg Brandl9166e1a2005-06-04 09:20:03 +00001859- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1863
Skip Montanaro174dd222005-05-14 20:54:16 +00001864- Patch #1120353: The xmlrpclib module provides better, more transparent,
1865 support for datetime.{datetime,date,time} objects. With use_datetime set
1866 to True, applications shouldn't have to fiddle with the DateTime wrapper
1867 class at all.
1868
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001869- distutils.commands.upload was added to support uploading distribution

1871
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001872- distutils.commands.register now encodes the data as UTF-8 before posting
1873 them to PyPI.
1874
Raymond Hettinger267b8682005-03-27 10:47:39 +00001875- decimal operator and comparison methods now return NotImplemented
1876 instead of raising a TypeError when interacting with other types. This
1877 allows other classes to implement __radd__ style methods and have them
1878 work as expected.
1879
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001880- Bug #1163325: Decimal infinities failed to hash. Attempting to
1881 hash a NaN raised an InvalidOperation instead of a TypeError.
1882
Tim Petersecc6e6a2005-07-10 22:30:55 +00001883- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001884 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1885

Martin v. Löwisa4dac402005-03-03 11:39:45 +00001895 profile.py if available.
1896
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001897- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1898

1903
Martin v. Löwise869eb12005-03-03 09:46:07 +00001904- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
1905
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00001906- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
1907
Martin v. Löwisdf241532005-03-03 08:17:42 +00001908- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
1909
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00001910- Patch #1104111: Alter setup.py --help and --help-commands.
1911

1917
Guido van Rossumd0641422005-02-03 15:01:24 +00001918- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1919 disables recursive traversal through instance attributes, which can
1920 be exploited in various ways.
1921
Tim Peterse3547fd2005-12-16 23:13:57 +00001922- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001923 flags on the HTTP listening socket.
1924
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001925- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1926 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1927
Fred Drakefbdeaad2006-07-29 16:56:15 +00001928- Patches #893642, #1039083: add allow_none, encoding arguments to
1929 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001930
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001931- Bug #1110478: Revert os.environ.update to do putenv again.

1934
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001935- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1936
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001937- Enhancements to the csv module:
1938
1939 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001940 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001941 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001942 + Dialect parameter parsing has been re-implemented to improve error
1943 reporting.
1944 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1945 dictates.
1946 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001947 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001948 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001949 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1950 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001951 + reader now allows \r characters to be quoted (previously it only allowed
1952 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001953 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001954 + Dialect classes passed to the module are no longer instantiated by
1955 the module before being parsed (the former validation scheme required
1956 this, but the mechanism was unreliable).
1957 + The dialect registry now contains instances of the internal
1958 C-coded dialect type, rather than references to python objects.
1959 + the internal c-coded dialect type is now immutable.
1960 + register_dialect now accepts the same keyword dialect specifications
1961 as the reader and writer, allowing the user to register dialects
1962 without first creating a dialect class.
1963 + a configurable limit to the size of parsed fields has been added -
1964 previously, an unmatched quote character could result in the entire
1965 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001966 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001967 the parser field size limit (returning the former limit). The initial
1968 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001969 + A line_num attribute has been added to the reader object, which tracks
1970 the number of lines read from the source iterator. This is not
1971 the same as the number of records returned, as records can span
1972 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001973 + reader and writer objects were not being registered with the cyclic-GC.
1974 This has been fixed.
1975
Brett Cannone6539c42005-01-08 02:43:53 +00001976- _DummyThread objects in the threading module now delete self.__block that is
1977 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1978 lock primitives tend to be limited in number and thus should not be wasted on
1979 a _DummyThread object. Fixes bug #1089632.
1980
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001981- The imghdr module now detects Exif files.
1982
Raymond Hettinger6065d322004-12-20 23:51:53 +00001983- StringIO.truncate() now correctly adjusts the size attribute.
1984 (Bug #951915).
1985
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001986- locale.py now uses an updated locale alias table (built using
1987 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1988 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001989 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001990
Raymond Hettinger3557f422004-12-07 12:02:02 +00001991- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1992
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001993- the pickle module no longer accepts the deprecated None option in the
1994 args tuple returned by __reduce__().
1995
Brett Cannon84667c02004-12-07 03:25:18 +00001996- optparse now optionally imports gettext. This allows its use in setup.py.
1997
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001998- the pickle module no longer uses the deprecated bin parameter.
1999
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002000- the shelve module no longer uses the deprecated binary parameter.
2001
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002002- the pstats module no longer uses the deprecated ignore() method.
2003
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002004- the filecmp module no longer uses the deprecated use_statcache argument.
2005
Raymond Hettinger664347b2004-12-04 21:21:53 +00002006- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2007 extended or overridden by subclasses. Formerly, the subclassed method would
2008 be ignored by the rest of the module. (Bug #1078905).
2009
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002010- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002011 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002012
Walter Dörwald36733692004-12-22 12:50:50 +00002013- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2014 once when a size argument is given. This prevents a buffer overflow in the
2015 tokenizer with very long source lines.
2016
Barry Warsaw538561e2006-01-01 21:48:54 +00002017- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2018 immediately after creating the object, without any intervening
2019 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002020
Skip Montanaro05885812005-01-16 20:48:27 +00002021- The reconvert.quote function can now emit triple-quoted strings. The
2022 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002023
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002024- ``UserString.MutableString`` now supports negative indices in
2025 ``__setitem__`` and ``__delitem__``
2026
Greg Ward40407942005-03-05 02:53:17 +00002027- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2028 correctly.
2029
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002030- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2031 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2032 character even if the user has passed a size parameter to get a proper
2033 line ending. Remove the special handling of a "\r\n" that has been split
2034 between two lines.
2035
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002036- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2037 about illegal code points. The codec now supports PEP 293 style error
2038 handlers.
2039
Walter Dörwald78a78b02005-09-01 12:04:29 +00002040- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002041 from the input stream, so that the output is a byte string in the correct
2042 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002043
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002044- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2045 considering it exactly like a '*'.
2046
Walter Dörwald007f8df2005-10-09 19:42:27 +00002047- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2048 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002049
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002050- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2051
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002052- Patch #1413711: Certain patterns of differences were making difflib
2053 touch the recursion limit.
2054
Walter Dörwald58917a62006-03-31 15:26:22 +00002055- Bug #947906: An object oriented interface has been added to the calendar
2056 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002057 called as a script (e.g. via ``python -mcalendar``). Localized month and
2058 weekday names can be ouput (even if an exotic encoding is used) using
2059 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002061Build
2062-----
2063
Neal Norwitz602d3392006-03-31 08:21:40 +00002064- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2065 by using -mieee gcc option.
2066

2068
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002069- Build support for Win64-AMD64 was added.
2070
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002071- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2072
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002073- Patch #881820: look for openpty and forkpty also in libbsd.
2074
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002075- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2076 The zlib module is now builtin on Windows.
2077
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002078- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2079
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002080- Bug #1189330: configure did not correctly determine the necessary
2081 value of LINKCC if python was built with GCC 4.0.
2082
Trent Mick8321b422005-07-26 02:29:21 +00002083- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2084 vulnerability in zlib 1.2.1 and 1.2.2.
2085
Brett Cannon08cd5982005-04-24 22:26:38 +00002086- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2087 flags that change binary compatibility. Changes were also made to
2088 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002089 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002090
Bob Ippolitoed233462005-03-29 13:47:59 +00002091- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2092 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2093 no longer exists). This configure patch makes things right.
2094
Martin v. Löwise2713be2005-03-08 15:03:08 +00002095- Bug #1158607: Build with --disable-unicode again.
2096
Brett Cannon46d96232005-02-16 00:07:19 +00002097- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2098 defined. Discovered as a result of not being able to build on OS X.
2099
Brett Cannon516592f2004-12-07 00:42:59 +00002100- setup.py now uses the directories specified in LDFLAGS using the -L option
2101 and in CPPFLAGS using the -I option for adding library and include
2102 directories, respectively, for compiling extension modules against. This has
2103 led to the core being compiled using the values in CPPFLAGS. It also removes
2104 the need for the special-casing of both DarwinPorts and Fink for darwin since
2105 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2106 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2107 Fink, ``-I/opt/local/include`` for DarwinPorts).
2108
Brett Cannon43802422005-02-10 20:48:03 +00002109- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2110 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2111 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2112 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002114C API
2115-----
2116
Tim Petersc9d78aa2006-03-26 23:27:58 +00002117- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2118 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2119 is obtained via the ``PyObject_`` family, it must be released via the
2120 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2121 always been officially true, but when Python's small-object allocator was
2122 introduced, an attempt was made to cater to a few extension modules
2123 discovered at the time that obtained memory via ``PyObject_New`` but
2124 released it via ``PyMem_DEL``. It's years later, and if such code still
2125 exists it will fail now (probably with segfaults, but calling wrong
2126 low-level memory management functions can yield many symptoms).
2127
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002128- Added a C API for set and frozenset objects.
2129
Raymond Hettinger66517482004-12-03 11:45:13 +00002130- Removed PyRange_New().
2131
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002132- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2133 mapping argument now. This string is used as a mapping table. Byte values
2134 greater than the length of the string and 0xFFFE are treated as undefined
2135 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002141- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002142
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002143- Patch #1276356: New resource "urlfetch" is implemented. This enables
2144 even impatient people to run tests that require remote files.
