91Core and builtins
92-----------------
93
Marc-André Lemburg040f76b2006-08-14 10:55:19 +000094- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000095 compared equal or unequal to a string and a UnicodeDecodeError
96 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +000097
Marc-André Lemburg040f76b2006-08-14 10:55:19 +000098 Instead, the equal (==) and unequal (!=) comparison operators will
99 now issue a UnicodeWarning and interpret the two objects as
100 unequal. The UnicodeWarning can be filtered as desired using
101 the warning framework, e.g. silenced completely, turned into an
102 exception, logged, etc.
103
104 Note that compare operators other than equal and unequal will still
105 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000106
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000107- Fix segfault when doing string formatting on subclasses of long.
108
109- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
110 with new-style classes.
111
112- Fix bug related to __len__ functions returning negative values with
113 classic classes.
114
115- Patch #1538606, Fix __index__() clipping. There were some problems
116 discovered with the API and how integers that didn't fit into Py_ssize_t
117 were handled. This patch attempts to provide enough alternatives
118 to effectively use __index__.
119
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000120- Bug #1536021: __hash__ may now return long int; the final hash
121 value is obtained by invoking hash on the long int.
122
Thomas Hellerab1049c2006-08-08 17:37:00 +0000123- Bug #1536786: buffer comparison could emit a RuntimeWarning.
124
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000125- Bug #1535165: fixed a segfault in input() and raw_input() when
126 sys.stdin is closed.
127
Thomas Heller74d36f02006-08-04 18:17:40 +0000128- On Windows, the PyErr_Warn function is now exported from
129 the Python dll again.
130
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000131- Bug #1191458: tracing over for loops now produces a line event
132 on each iteration. Fixing this problem required changing the .pyc
133 magic number. This means that .pyc files generated before 2.5c1
134 will be regenerated.
135
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000136- Bug #1333982: string/number constants were inappropriately stored
137 in the byte code and co_consts even if they were not used, ie
138 immediately popped off the stack.
139
Georg Brandle9462c72006-08-04 18:03:37 +0000140- Fixed a reference-counting problem in property().

143Library
144-------
145
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000146- Fix a bug in the ``compiler`` package that caused invalid code to be
147 generated for generator expressions.
148
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000149- The distutils version has been changed to 2.5.0. The change to
150 keep it programmatically in sync with the Python version running
151 the code (introduced in 2.5b3) has been reverted. It will continue
152 to be maintained manually as static string literal.
153
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000154- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000155 and this cannot be converted to the required C type, an exception is
156 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000157 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000158
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000159- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000160 an exception.
161
Tim Peterscbdd3502006-09-05 01:47:53 +0000162- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000163 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000164 workarounds for clocks with low resolution, to stop the code yielding
165 duplicate UUIDs.
166
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000167- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
168 before raising SystemExit, allowing IDLE to honor quit() and exit().
169
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000170- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
171
Georg Brandl7a1af772006-08-14 21:55:28 +0000172- Patch #1536071: trace.py should now find the full module name of a
173 file correctly even on Windows.
174
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000175- logging's atexit hook now runs even if the rest of the module has
176 already been cleaned up.
177
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000178- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000179
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000180- Bug #1531405, format_exception no longer raises an exception if
181 str(exception) raised an exception.
182
Neil Schemenauer06ded092006-08-04 16:20:30 +0000183- Fix a bug in the ``compiler`` package that caused invalid code to be
184 generated for nested functions.

Georg Brandl3335a7a2006-08-14 21:42:55 +0000192- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
193 raises the correct exceptions.
194
Thomas Heller1ce433e2006-08-14 16:20:04 +0000195- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
196 '-no-stack-protector' compiler flag for OpenBSD has been removed.
197
Thomas Heller86720042006-08-14 11:17:48 +0000198- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
199 uses the _as_parameter_ attribute when objects are passed to foreign
200 function calls. The ctypes version number was changed to 1.0.1.
201
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000202- Bug #1530559, struct.pack raises TypeError where it used to convert.
203 Passing float arguments to struct.pack when integers are expected
204 now triggers a DeprecationWarning.
205

Andrew MacIntyre16ee33a2006-08-06 12:37:03 +0000217- test_threading now skips testing alternate thread stack sizes on
218 platforms that don't support changing thread stack size.
219
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000220

Neal Norwitza1f10902006-07-12 07:28:29 +0000253
254Core and builtins
255-----------------
256
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000257- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000258 returned a long (see PEP 353).
259
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000260- Bug #1515471: string.replace() accepts character buffers again.
261
Neal Norwitz07aadb12006-07-30 06:55:48 +0000262- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
263 This provides the proper warning for struct.pack().
264 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
265
Neal Norwitz0d62a062006-07-30 06:53:31 +0000266- Patch #1531113: Fix augmented assignment with yield expressions.
267 Also fix a SystemError when trying to assign to yield expressions.
268
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000269- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
270 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
271 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
272 excessive filesystem operations during imports.
273
Tim Petersbc24eee2006-07-27 01:14:53 +0000274- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
275 operations on signed longs that are formally undefined by C.
276 Unfortunately, at least one compiler now cares about that, so complicated
277 the code to make that compiler happy again.
278
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000279- Bug #1524310: Properly report errors from FindNextFile in os.listdir.

282 path on Windows.
283
Neal Norwitze1fdb322006-07-21 05:32:28 +0000284- Fix some potential crashes found with failmalloc.
285
Neal Norwitze7563102006-07-17 01:00:16 +0000286- Fix warnings reported by Klocwork's static analysis tool.
287
Neal Norwitz84be93b2006-07-16 01:50:38 +0000288- Bug #1512814, Fix incorrect lineno's when code within a function
289 had more than 255 blank lines.
290
Georg Brandl9dceedb2006-07-12 15:31:17 +0000291- Patch #1521179: Python now accepts the standard options ``--help`` and
292 ``--version`` as well as ``/?`` on Windows.
293
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000294- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000295 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000296 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000297
Tim Peters112aad32006-07-19 00:03:19 +0000298- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000299 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000300 new ``sys._current_frames()`` returns a dictionary with one entry,
301 mapping the faux "thread id" 0 to the current frame.
302
Ronald Oussoren3075e162006-07-25 20:28:55 +0000303- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

Martin v. Löwis961b91b2006-08-02 13:53:55 +0000309- Correction of patch #1455898: In the mbcs decoder, set final=False
310 for stream decoder, but final=True for the decode function.
311
Georg Brandl07fec3a2006-08-01 18:49:24 +0000312- os.urandom no longer masks unrelated exceptions like SystemExit or
313 KeyboardInterrupt.
314
Tim Peters4643c2f2006-08-10 22:45:34 +0000315- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000316 shutil.copytree on Windows
317
Georg Brandle34ac7c2006-07-30 11:07:23 +0000318- Bug #1002398: The documentation for os.path.sameopenfile now correctly
319 refers to file descriptors, not file objects.
320
Tim Peterscbdd3502006-09-05 01:47:53 +0000321- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000322 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000323 #1513611, and probably others.
324
Georg Brandledd9b0d2006-07-29 09:33:26 +0000325- Bug #1441397: The compiler module now recognizes module and function
326 docstrings correctly as it did in Python 2.4.
327
Tim Peters6f681472006-07-27 23:44:37 +0000328- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
329 lost that tests are sorted by name before being run. This rarely
330 matters for well-written tests, but can create baffling symptoms if
331 side effects from one test to the next affect outcomes. ``DocTestFinder``
332 has been changed to sort the list of tests it returns.
333
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000334- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000335 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000336
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000337- Bug #978833: Really close underlying socket in _socketobject.close.
338
Georg Brandldb232dc2006-08-20 13:15:43 +0000339- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
340 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000341
Georg Brandlcf0c1722006-07-26 07:23:32 +0000342- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
343 to recursive calls and call it with the failing package name.
344
Martin v. Löwis0b483032006-07-25 09:53:12 +0000345- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
346
Georg Brandlc13c34c2006-07-24 14:09:56 +0000347- Patch #1515343: Fix printing of deprecated string exceptions with a
348 value in the traceback module.
349
Greg Ward48fae7a2006-07-23 16:05:51 +0000350- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
351
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000352- Patch #1524429: Use repr() instead of backticks in Tkinter again.
353
Brett Cannoncaebe222006-07-18 04:41:36 +0000354- Bug #1520914: Change time.strftime() to accept a zero for any position in its
355 argument tuple. For arguments where zero is illegal, the value is forced to
356 the minimum value that is correct. This is to support an undocumented but
357 common way people used to fill in inconsequential information in the time
358 tuple pre-2.4.
359
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000360- Patch #1220874: Update the binhex module for Mach-O.
361
Barry Warsawb110bad2006-07-21 14:51:07 +0000362- The email package has improved RFC 2231 support, specifically for
363 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
364 (name*0=<blah>) parameter continuations. This may change the types of
365 values returned from email.message.Message.get_param() and friends.
366 Specifically in some cases where non-encoded continuations were used,
367 get_param() used to return a 3-tuple of (None, None, string) whereas now it
368 will just return the string (since non-encoded continuations don't have
369 charset and language parts).
370
371 Also, whereas % values were decoded in all parameter continuations, they are
372 now only decoded in encoded parameter parts.
373
Ronald Oussoren3075e162006-07-25 20:28:55 +0000374- Bug #1517990: IDLE keybindings on MacOS X now work correctly
375
376- Bug #1517996: IDLE now longer shows the default Tk menu when a
377 path browser, class browser or debugger is the frontmost window on MacOS X
378
Barry Warsaw00decd72006-07-27 23:43:15 +0000379- Patch #1520294: Support for getset and member descriptors in types.py,
380 inspect.py, and pydoc.py. Specifically, this allows for querying the type
381 of an object against these built-in types and more importantly, for getting
382 their docstrings printed in the interactive interpreter's help() function.

386-----------------
387
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000388- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
389 a socket operation on a socket with a timeout, the exception will be
390 caught correctly. Previously, the exception was not caught.
391
Thomas Heller1393d6a2006-07-28 21:43:20 +0000392- Patch #1529514: The _ctypes extension is now compiled on more
393 openbsd target platforms.
394
Tim Peters9cab5932006-07-28 00:30:00 +0000395- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
396 a memory leak, affecting pickles and deep copies.
397
Tim Petersbc24eee2006-07-27 01:14:53 +0000398- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000399 Paul Eggert.
400
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000401- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
402
Thomas Hellerce049a02006-07-14 17:51:14 +0000403- Patch #1521817: Index range checking on ctypes arrays containing
404 exactly one element enabled again. This allows iterating over these
405 arrays, without the need to check the array size before.
406
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000407- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000408 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000409 /dev/null in certain cases; this is now fixed.
410
Thomas Heller47d7a062006-07-12 08:43:47 +0000411- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
412 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000413
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000414- Because of a misspelled preprocessor symbol, ctypes was always
415 compiled without thread support; this is now fixed.
416
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000417- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
418 methods now allow their database parameter to be None as the
419 sleepycat API allows.
420
Matt Flemingec926502006-07-28 11:27:27 +0000421- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
422 bluetooth API compared with Linux and FreeBSD.
423
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000424Tests
425-----
426
427- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
428 how long the test file should take to play. Now accepts taking 2.93 secs
429 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
430
Georg Brandl4793aa32006-07-28 18:31:39 +0000431- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
432 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
433 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000434

437
438- Bug #1439538: Drop usage of test -e in configure as it is not portable.
439
Ronald Oussoren26cad082006-08-01 21:00:57 +0000440Mac
441---
442
443- PythonLauncher now works correctly when the path to the script contains
444 characters that are treated specially by the shell (such as quotes).
445
446- Bug #1527397: PythonLauncher now launches scripts with the working directory
447 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000448 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000449 expect.

457Core and builtins
458-----------------
459
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000460- Bug #1441486: The literal representation of -(sys.maxint - 1)
461 again evaluates to a int object, not a long.
462
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000463- Bug #1501934: The scope of global variables that are locally assigned
464 using augmented assignment is now correctly determined.
465
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000466- Bug #927248: Recursive method-wrapper objects can now safely
467 be released.
468
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000469- Bug #1417699: Reject locale-specific decimal point in float()
470 and atof().
471
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000472- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
473 omit a default "error" argument for NULL pointer. This allows
474 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000475
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000476- Bug #1519018: 'as' is now validated properly in import statements.
477
Neal Norwitz28746ab2006-07-09 22:14:42 +0000478- On 64 bit systems, int literals that use less than 64 bits are
479 now ints rather than longs.
480
Neal Norwitzed657552006-07-10 00:04:44 +0000481- Bug #1512814, Fix incorrect lineno's when code at module scope
482 started after line 256.
483
Tim Peters32a83612006-07-10 21:08:24 +0000484- New function ``sys._current_frames()`` returns a dict mapping thread
485 id to topmost thread stack frame. This is for expert use, and is
486 especially useful for debugging application deadlocks. The functionality
487 was previously available in Fazal Majid's ``threadframe`` extension
488 module, but it wasn't possible to do this in a wholly threadsafe way from
489 an extension.

Tim Peters32a83612006-07-10 21:08:24 +0000499- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000500 environment variable to be set in order to the SDK environment

506
Thomas Woutersadd19112006-07-05 11:03:49 +0000507- string.Template() now correctly handles tuple-values. Previously,
508 multi-value tuples would raise an exception and single-value tuples would
509 be treated as the value they contain, instead.
510
Martin v. Löwisede77f52006-07-03 13:01:35 +0000511- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
512 even if some data are received.

Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000520- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000521 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000522

524 is created.
525

533 sgmllib ('[' and ']' were not accepted).
534
Georg Brandl1be63af2006-06-28 20:23:25 +0000535- Fix a bug in the turtle module's end_fill function.
536
Brett Cannon53ab5b72006-06-22 16:49:14 +0000537- Bug #1510580: The 'warnings' module improperly required that a Warning
538 category be either a types.ClassType and a subclass of Warning. The proper
539 check is just that it is a subclass with Warning as the documentation states.
540
Georg Brandlad29e632006-06-21 17:45:17 +0000541- The compiler module now correctly compiles the new try-except-finally
542 statement (bug #1509132).
543
Neal Norwitz60373cd2006-06-22 06:30:50 +0000544- The wsgiref package is now installed properly on Unix.
545
Vinay Sajip28e57612006-07-01 10:45:20 +0000546- A bug was fixed in logging.config.fileConfig() which caused a crash on
547 shutdown when fileConfig() was called multiple times.
548
Gerhard Häring762fbd32006-07-02 17:48:30 +0000549- The sqlite3 module did cut off data from the SQLite database at the first
550 null character before sending it to a custom converter. This has been fixed
551 now.

554-----------------
555
Tim Peters112aad32006-07-19 00:03:19 +0000556- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
557 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
558 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000559
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000560- Assigning None to pointer type fields in ctypes structures possible
561 overwrote the wrong fields, this is fixed now.
562
563- Fixed a segfault in _ctypes when ctypes.wintypes were imported
564 on non-Windows platforms.
565
566- Bug #1518190: The ctypes.c_void_p constructor now accepts any
567 integer or long, without range checking.
568
569- Patch #1517790: It is now possible to use custom objects in the ctypes
570 foreign function argtypes sequence as long as they provide a from_param
571 method, no longer is it required that the object is a ctypes type.
572
573- The '_ctypes' extension module now works when Python is configured
574 with the --without-threads option.
575
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000576- Bug #1513646: os.access on Windows now correctly determines write

591
Tim Peters32a83612006-07-10 21:08:24 +0000592- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000593 Previously, the slight difference could cause compilation errors of the
594 'zlib' module on systems with more than one version of zlib.
595
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000596- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +0000626
627Core and builtins
628-----------------
629
Georg Brandla56b9152006-06-19 06:35:54 +0000630- Patch #1507676: Error messages returned by invalid abstract object operations
631 (such as iterating over an integer) have been improved and now include the
632 type of the offending object to help with debugging.
633
Brett Cannonea3912b2006-06-13 21:46:41 +0000634- Bug #992017: A classic class that defined a __coerce__() method that returned
635 its arguments swapped would infinitely recurse and segfault the interpreter.
636
Neal Norwitz909eb122006-06-12 02:13:21 +0000637- Fix the socket tests so they can be run concurrently.
638
Neal Norwitzb9845e72006-06-12 02:11:18 +0000639- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000640 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000641
Brett Cannon22565aa2006-06-09 22:31:23 +0000642- Bug #532646: object.__call__() will continue looking for the __call__
643 attribute on objects until one without one is found. This leads to recursion
644 when you take a class and set its __call__ attribute to an instance of the
645 class. Originally fixed for classic classes, but this fix is for new-style.
646 Removes the infinite_rec_3 crasher.
647
Georg Brandl24250812006-06-09 18:45:48 +0000648- The string and unicode methods startswith() and endswith() now accept
649 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
650
Brett Cannonde3b0522006-06-08 17:00:45 +0000651- Buffer objects, at the C level, never used the char buffer
652 implementation even when the char buffer for the wrapped object was
653 explicitly requested (originally returned the read or write buffer).
654 Now a TypeError is raised if the char buffer is not present but is
655 requested.
656
Georg Brandlddbaa662006-06-04 21:56:52 +0000657- Patch #1346214: Statements like "if 0: suite" are now again optimized
658 away like they were in Python 2.4.
659
Georg Brandlb7c8f542006-05-27 12:30:25 +0000660- Builtin exceptions are now full-blown new-style classes instead of
661 instances pretending to be classes, which speeds up exception handling
662 by about 80% in comparison to 2.5a2.
663
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000664- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
665 Unicode 4.1.
666
Georg Brandlf4ef1162006-05-26 18:03:31 +0000667- Patch #921466: sys.path_importer_cache is now used to cache valid and
668 invalid file paths for the built-in import machinery which leads to
669 fewer open calls on startup.
670
Tim Peters696cf432006-05-24 21:10:40 +0000671- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
672 of-2 bases. The largest speedup is for inputs with about 1000 decimal
673 digits. Conversion from non-power-of-2 bases remains quadratic-time in
674 the number of input digits (it was and remains linear-time for bases
675 2, 4, 8, 16 and 32).
676
Tim Petersb713ec22006-05-23 18:45:30 +0000677- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
678 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
679 an integer close to ``sys.maxint``. This was repaired by patch
680 #1335972, which also gives a nice speedup.
681
Richard Jonescebbefc2006-05-23 18:28:17 +0000682- Patch #1337051: reduced size of frame objects.
683
684- PyErr_NewException now accepts a tuple of base classes as its
685 "base" parameter.
686
Richard Jones7c88dcc2006-05-23 10:37:38 +0000687- Patch #876206: function call speedup by retaining allocated frame
688 objects.
689
Georg Brandl7b90e162006-05-18 07:01:27 +0000690- Bug #1462152: file() now checks more thoroughly for invalid mode
691 strings and removes a possible "U" before passing the mode to the
692 C library function.
693
Neal Norwitz1004a532006-05-15 07:17:23 +0000694- Patch #1488312, Fix memory alignment problem on SPARC in unicode
695
Neal Norwitz373f0a72006-05-15 07:04:36 +0000696- Bug #1487966: Fix SystemError with conditional expression in assignment
697
Martin v. Löwis879768d2006-05-11 13:28:43 +0000698- WindowsError now has two error code attributes: errno, which carries
699 the error values from errno.h, and winerror, which carries the error
700 values from winerror.h. Previous versions put the winerror.h values
701 (from GetLastError()) into the errno attribute.
702
Martin v. Löwis77736712006-05-04 05:51:03 +0000703- Patch #1475845: Raise IndentationError for unexpected indent.
704
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000705- Patch #1479181: split open() and file() from being aliases for each other.
706
Tim Peters44bd9862006-06-01 13:49:23 +0000707- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
708 methods were always silently ignored by dictionaries when comparing keys.
709 They are now passed through (except when using the C API function
710 ``PyDict_GetItem()``, whose semantics did not change).
711
712- Bug #1456209: In some obscure cases it was possible for a class with a
713 custom ``__eq__()`` method to confuse dict internals when class instances
714 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
715 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000717Extension Modules
718-----------------
719
Trent Mick960a3f82006-06-28 20:30:41 +0000720- Bug #1295808: expat symbols should be namespaced in pyexpat
721
722- Patch #1462338: Upgrade pyexpat to expat 2.0.0
723
Brett Cannon6ee7d012006-06-08 16:23:04 +0000724- Change binascii.hexlify to accept a read-only buffer instead of only a char
725 buffer and actually follow its documentation.
726
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000727- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
728
Nick Coghlanc649ec52006-05-29 12:43:05 +0000729- Patch #1478788 (modified version): The functional extension module has
730 been renamed to _functools and a functools Python wrapper module added.
731 This provides a home for additional function related utilities that are
732 not specifically about functional programming. See PEP 309.
733
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000734- Patch #1493701: performance enhancements for struct module.
735
Georg Brandl378d5922006-05-17 14:26:50 +0000736- Patch #1490224: time.altzone is now set correctly on Cygwin.
737
Georg Brandl8d3342b2006-05-16 07:38:27 +0000738- Patch #1435422: zlib's compress and decompress objects now have a
739 copy() method.
740
Andrew MacIntyre92913322006-06-13 15:04:24 +0000741- Patch #1454481: thread stack size is now tunable at runtime for thread
742 enabled builds on Windows and systems with Posix threads support.
743
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000744- On Win32, os.listdir now supports arbitrarily-long Unicode path names
745 (up to the system limit of 32K characters).
746
747- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
748 As a result, these functions now raise WindowsError instead of OSError.
749
Tim Peters7a822da2006-05-25 21:50:17 +0000750- ``time.clock()`` on Win64 should use the high-performance Windows
751 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
752 Windows platforms).
753
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000754- Calling Tk_Init twice is refused if the first call failed as that
755 may deadlock.
756
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000757- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
758 accept it without potentially using an uninitialized pointer.
759
760- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
761 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
762 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000763
Gregory P. Smith372b5832006-06-05 18:48:21 +0000764- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000765 [pybsddb project SF patch number 1466734]
766
Gregory P. Smith372b5832006-06-05 18:48:21 +0000767- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
768 parameter is supplied. [SF pybsddb bug #1477863]
769
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000770- bsddb: the __len__ method of a DB object has been fixed to return correct
771 results. It could previously incorrectly return 0 in some cases.
772 Fixes SF bug 1493322 (pybsddb bug 1184012).
773
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000774- bsddb: the bsddb.dbtables Modify method now raises the proper error and
775 aborts the db transaction safely when a modifier callback fails.
776 Fixes SF python patch/bug #1408584.
777
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000778- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000779 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000780 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
781 database calls that would previously deadlock. [SF python bug #775414]
782
Vinay Sajip28e57612006-07-01 10:45:20 +0000783- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000784
Walter Dörwald4994d952006-06-19 08:07:50 +0000785- Patch #1506645: add Python wrappers for the curses functions
786 is_term_resized, resize_term and resizeterm.

789-------
790
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000791- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
792 functions.
793
Martin v. Löwis3798da02006-06-17 18:44:27 +0000794- Patch #812986: Update turtle output even if not tracing.
795
Vinay Sajip28e57612006-07-01 10:45:20 +0000796- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000797 Tkinter.BaseWidget.
798
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000799- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
800
Martin v. Löwis337487e2006-06-17 09:15:14 +0000801- Patch #763580: Add name and value arguments to Tkinter variable
802 classes.
803
Georg Brandl83cc0d02006-06-14 08:50:03 +0000804- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
805 mime.types file for determining MIME types.
806
Georg Brandl2605ca82006-06-14 06:08:31 +0000807- Bug #1339007: Shelf objects now don't raise an exception in their
808 __del__ method when initialization failed.
809
Martin v. Löwisd8251432006-06-14 05:21:04 +0000810- Patch #1455898: The MBCS codec now supports the incremental mode for
811 double-byte encodings.
812
Tim Peters43898b42006-06-14 04:09:25 +0000813- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
814 guarantee that adjacent triples in the return list always describe
815 non-adjacent blocks. Previously, a pair of matching blocks could end
816 up being described by multiple adjacent triples that formed a partition
817 of the matching pair.
818
Greg Ward0e0c9f42006-06-11 16:24:11 +0000819- Bug #1498146: fix optparse to handle Unicode strings in option help,
820 description, and epilog.
821
Greg Wardd1c797e2006-06-11 14:42:41 +0000822- Bug #1366250: minor optparse documentation error.
823
Greg Ward7f547402006-06-11 00:40:49 +0000824- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
825 clarify docs.
826
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000827- The wsgiref package has been added to the standard library.
828
Nick Coghlan676725d2006-06-08 13:54:49 +0000829- The functions update_wrapper() and wraps() have been added to the functools
830 module. These make it easier to copy relevant metadata from the original
831 function when writing wrapper functions.
832
Tim Petersd6a9eef2006-06-05 01:48:21 +0000833- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
834 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000835
Martin v. Löwis3f767792006-06-04 19:36:28 +0000836- Patch #1359618: Speed up charmap encoder by using a trie structure
837 for lookup.
838
Tim Petersd609b1a2006-06-02 23:22:51 +0000839- The functions in the ``pprint`` module now sort dictionaries by key
840 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
841 if and only if its display required more than one line, although that
842 wasn't documented. The new behavior increases predictability; e.g.,
843 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
844
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000845- Patch #1497027: try HTTP digest auth before basic auth in urllib2
846 (thanks for J. J. Lee).
847
Georg Brandl2b330372006-05-28 20:23:12 +0000848- Patch #1496206: improve urllib2 handling of passwords with respect to
849 default HTTP and HTTPS ports.
850
George Yoshidaf3c65de2006-05-28 16:39:09 +0000851- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
852
Bob Ippolito7298f272006-05-23 18:43:47 +0000853- Patch #1281707: speed up gzip.readline.
854
Georg Brandlb89316f2006-05-17 15:51:16 +0000855- Patch #1180296: Two new functions were added to the locale module:
856 format_string() to get the effect of "format % items" but locale-aware,
857 and currency() to format a monetary number with currency sign.
858
Georg Brandle3a25832006-05-17 14:56:04 +0000859- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
860 and several features added, such as speed and geometry control.
861
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000862- Patch #1488881: add support for external file objects in bz2 compressed
863 tarfiles.
864
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000865- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
866 stdout arguments, making it possible to redirect input and output
867 for remote debugging.
868
869- Patch #1484695: Update the tarfile module to version 0.8. This fixes
870 a couple of issues, notably handling of long file names using the
871 GNU LONGNAME extension.
872
873- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
874 new flag when ``name`` is already the name of an option flag.
875
876- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
877 package.
878
879- Patch #1472854: make the rlcompleter.Completer class usable on non-
880 UNIX platforms.
881
882- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
883
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000884- Bug #1472827: correctly escape newlines and tabs in attribute values in
885 the saxutils.XMLGenerator class.

920Core and builtins
921-----------------
922
Thomas Heller1b046642006-04-18 18:51:06 +0000923- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
924 by converting these apis from macros into exported functions again:
925
926 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile

Martin v. Löwis45294a92006-04-18 06:24:08 +0000932- Under COUNT_ALLOCS, types are not necessarily immortal anymore.

Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000934- All uses of PyStructSequence_InitType have been changed to initialize
935 the type objects only once, even if the interpreter is initialized
936 multiple times.
937
Neal Norwitz61546162006-04-14 05:20:28 +0000938- Bug #1454485, array.array('u') could crash the interpreter. This was
939 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
940 to unicode when it didn't make sense. 'u#' now requires a unicode string.
941
942- Py_UNICODE is unsigned. It was always documented as unsigned, but
943 due to a bug had a signed value in previous versions.
944
Tim Peters3a5e8b12006-04-11 01:44:07 +0000945- Patch #837242: ``id()`` of any Python object always gives a positive
946 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
947 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000948 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000949 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000950
Tim Peters3a5e8b12006-04-11 01:44:07 +0000951 def __hash__(self):
952 return id(self) # WRONG
953
954 because a hash result must be a (short) Python int but it was always
955 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000956 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000957 was always usable as a hash value before this patch. That's no longer
958 necessarily so.
959
960- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000961 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000962 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000963 #1454844)
964
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000965- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
966 involving generators that have paused outside of any ``try`` or ``with``
967 blocks. (In 2.5a1, a paused generator that was part of a reference
968 cycle could not be garbage collected, regardless of whether it was
969 paused in a ``try`` or ``with`` block.)

975 is a macro.
976
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000977- Bug #1467952: os.listdir() now correctly raises an error if readdir()
978 fails with an error condition.
979
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000980- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
981
982- Bug #1117761: bsddb.*open() no longer raises an exception when using
983 the cachesize parameter.
984
985- Bug #1149413: bsddb.*open() no longer raises an exception when using
986 a temporary db (file=None) with the 'n' flag to truncate on open.
987
988- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
989 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000990
Armin Rigoa9017c32006-04-19 11:50:27 +0000991- Patch #1062014: AF_UNIX sockets under Linux have a special
992 abstract namespace that is now fully supported.
993

995-------
996
Peter Astrand7d1d4362006-07-14 14:04:45 +0000997- Bug #1223937: subprocess.CalledProcessError reports the exit status
998 of the process using the returncode attribute, instead of
999 abusing errno.
1000
Tim Peters711bf302006-04-25 03:31:36 +00001001- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1002 a doctest to be skipped (the code is not run, and the expected output
1003 or exception is ignored).
1004
Nick Coghlanda2268f2006-04-24 04:37:15 +00001005- Fixed contextlib.nested to cope with exceptions being raised and
1006 caught inside exit handlers.
1007
Greg Wardab05edc2006-04-23 03:47:58 +00001008- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1009 hex, octal, or binary; add ``append_const`` action; keep going if
1010 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1011 added ``epilog`` for better help generation).
1012
Tim Peters21fbd572006-04-21 21:18:10 +00001013- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1014 called from a thread spawned as a side effect of importing a module.
1015
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001016- The pydoc module now supports documenting packages contained in
1017 .zip or .egg files.
1018
1019- The pkgutil module now has several new utility functions, such
1020 as ``walk_packages()`` to support working with packages that are either
1021 in the filesystem or zip files.
1022
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001023- The mailbox module can now modify and delete messages from
1024 mailboxes, in addition to simply reading them. Thanks to Gregory
1025 K. Johnson for writing the code, and to the 2005 Google Summer of
1026 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001027
Tim Petersc7605f22006-04-17 21:12:33 +00001028- The ``__del__`` method of class ``local`` in module ``_threading_local``
1029 returned before accomplishing any of its intended cleanup.
1030

1036
Anthony Baxtere29002c2006-04-12 12:07:31 +00001037- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1038 Windows. Bug #1469163.
1039
Phillip J. Eby47032112006-04-11 01:07:43 +00001040- The warnings, linecache, inspect, traceback, site, and doctest modules
1041 were updated to work correctly with modules imported from zipfiles or
1042 via other PEP 302 __loader__ objects.
1043
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001044- Patch #1467770: Reduce usage of subprocess._active to processes which
1045 the application hasn't waited on.

1050
Skip Montanaro262fb922006-04-21 02:31:07 +00001051- The pstats.Stats class accepts an optional stream keyword argument to
1052 direct output to an alternate file-like object.
1053
Anthony Baxter51bcb682006-04-05 14:51:42 +00001054Build
1055-----
1056
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001057- The Makefile now has a reindent target, which runs reindent.py on
1058 the library.
1059
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001060- Patch #1470875: Building Python with MS Free Compiler
1061
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001062- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001063
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001064- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1065 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001066 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001067 CXX from --with-cxx-main, see description in README.
1068
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001069- Patch #1429775: Link extension modules with the shared libpython.
1070
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001071- Fixed a libffi build problem on MIPS systems.
1072
Tim Peters8931ff12006-05-13 23:28:20 +00001073- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1074 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1075 and "%zu" for unsigned integers of type ``size_t``.
1076
Anthony Baxter51bcb682006-04-05 14:51:42 +00001077Tests
1078-----
1079
Nick Coghlanda2268f2006-04-24 04:37:15 +00001080- test_contextlib now checks contextlib.nested can cope with exceptions
1081 being raised and caught inside exit handlers.
1082
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001083- test_cmd_line now checks operation of the -m and -c command switches
1084
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001085- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1086 it separately and by hand. It also wasn't cleaning up its changes to
1087 the current Decimal context.
1088
Thomas Woutersabd08882006-04-26 15:53:30 +00001089- regrtest.py now has a -M option to run tests that test the new limits of
1090 containers, on 64-bit architectures. Running these tests is only sensible
1091 on 64-bit machines with more than two gigabytes of memory. The argument
1092 passed is the maximum amount of memory for the tests to use.

1101-------------
1102
Tim Petersb06d28c2006-05-12 01:57:59 +00001103- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1104
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001105- PEP 343: Added Context Types section to the library reference
1106 and attempted to bring other PEP 343 related documentation into
1107 line with the implementation and/or python-dev discussions.
1108
Tim Peters8dc73d22006-04-24 02:03:16 +00001109- Bug #1337990: clarified that ``doctest`` does not support examples
1110 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001113What's New in Python 2.5 alpha 1?
1114=================================
1115
Anthony Baxterebed3f62006-04-03 15:03:44 +00001116*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001117
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001118Core and builtins
1119-----------------
1120
Nick Coghlan43832302006-04-23 17:04:07 +00001121- PEP 338: -m command line switch now delegates to runpy.run_module
1122 allowing it to support modules in packages and zipfiles
1123
Martin v. Löwisc661b882006-04-20 04:54:23 +00001124- On Windows, .DLL is not an accepted file name extension for
1125 extension modules anymore; extensions are only found if they
1126 end in .PYD.
1127
Martin v. Löwisea62d252006-04-03 10:56:49 +00001128- Bug #1421664: sys.stderr.encoding is now set to the same value as
1129 sys.stdout.encoding.
1130
Neal Norwitz92e212f2006-04-03 04:48:37 +00001131- __import__ accepts keyword arguments.
1132
Georg Brandlccadf842006-03-31 18:54:53 +00001133- Patch #1460496: round() now accepts keyword arguments.
1134
Anthony Baxter262c00a2006-03-30 10:53:17 +00001135- Fixed bug #1459029 - unicode reprs were double-escaped.
1136
Hye-Shik Changd478f342006-03-23 12:32:36 +00001137- Patch #1396919: The system scope threads are reenabled on FreeBSD
1138 5.4 and later versions.
1139
Neal Norwitze98ccf62006-03-23 05:39:47 +00001140- Bug #1115379: Compiling a Unicode string with an encoding declaration
1141 now gives a SyntaxError.
1142
Georg Brandlabd1ff82006-03-18 07:59:59 +00001143- Previously, Python code had no easy way to access the contents of a
1144 cell object. Now, a ``cell_contents`` attribute has been added
1145 (closes patch #1170323).
1146
Tim Peterscf79aac2006-03-16 01:14:46 +00001147- Patch #1123430: Python's small-object allocator now returns an arena to
1148 the system ``free()`` when all memory within an arena becomes unused
1149 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1150 freed. Some applications will see a drop in virtual memory size now,
1151 especially long-running applications that, from time to time, temporarily
1152 use a large number of small objects. Note that when Python returns an
1153 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001154 platform C library will in turn return that memory to the operating system.
1155 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001156 appears to be effective at least on Microsoft C and gcc-based systems.
1157 Thanks to Evan Jones for hard work and patience.
1158
Georg Brandl533ff6f2006-03-08 18:09:27 +00001159- Patch #1434038: property() now uses the getter's docstring if there is
1160 no "doc" argument given. This makes it possible to legitimately use
1161 property() as a decorator to produce a read-only property.
1162
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001163- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1164 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1165 of requiring an int or long in slicing and a few other contexts, enabling
1166 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1167
Neal Norwitz995acdf2006-03-07 05:01:00 +00001168- Fixed various bugs reported by Coverity's Prevent tool.
1169
Brett Cannonbf364092006-03-01 04:25:17 +00001170- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1171 new exception base class, BaseException, which has a new message attribute.
1172 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1173 Raising a string exception now raises a DeprecationWarning.
1174
Thomas Woutersfb609f42006-02-28 16:37:25 +00001175- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1176 explicitly relative, using 'from .module import name' to mean 'from the same
1177 package as this module is in. Imports without dots still default to the
1178 old relative-then-absolute, unless 'from __future__ import
1179 absolute_import' is used.
1180
Brett Cannona7446e32006-02-27 23:39:10 +00001181- Properly check if 'warnings' raises an exception (usually when a filter set
1182 to "error" is triggered) when raising a warning for raising string
1183 exceptions.
1184
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001185- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001186 The name was removed from Include/code.h.
1187
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001188- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001189
Guido van Rossum1968ad32006-02-25 22:38:04 +00001190- Patch 1433928:
1191 - The copy module now "copies" function objects (as atomic objects).
1192 - dict.__getitem__ now looks for a __missing__ hook before raising
1193 KeyError.
1194
Tim Peters84ef21c2006-02-28 20:39:06 +00001195- PEP 343: with statement implemented. Needs ``from __future__ import
1196 with_statement``. Use of 'with' as a variable will generate a warning.
1197 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001198 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001199 The following objects have __context__ methods:
1200 - The built-in file type.
1201 - The thread.LockType type.
1202 - The following types defined by the threading module:
1203 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1204 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001205
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001206- Fix the encodings package codec search function to only search
1207 inside its own package. Fixes problem reported in patch #1433198.
1208
1209 Note: Codec packages should implement and register their own
1210 codec search function. PEP 100 has the details.
1211
Tim Peters9ea89d22006-06-04 03:26:02 +00001212- PEP 353: Using ``Py_ssize_t`` as the index type.
1213
1214- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1215 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1216 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1217 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1218 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001219
Neal Norwitzfc76d632006-01-10 06:03:13 +00001220- Patch #1400181, fix unicode string formatting to not use the locale.
1221 This is how string objects work. u'%f' could use , instead of .
1222 for the decimal point. Now both strings and unicode always use periods.
1223
Neal Norwitz671b9e32006-01-09 07:07:12 +00001224- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1225 configure would break checking curses.h.
1226
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001227- Bug #959576: The pwd module is now builtin. This allows Python to be
1228 built on UNIX platforms without $HOME set.
1229
Neal Norwitzc10978f2005-12-19 06:07:16 +00001230- Bug #1072182, fix some potential problems if characters are signed.
1231
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001232- Bug #889500, fix line number on SyntaxWarning for global declarations.
1233
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001234- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1235
Neal Norwitze7214a12005-12-18 05:03:17 +00001236- Support for converting hex strings to floats no longer works.
1237 This was not portable. float('0x3') now raises a ValueError.
1238
Barry Warsaw2a38a862005-12-18 01:27:35 +00001239- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001240 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001241 is now displayed in interactive prompt banner.
1242
Georg Brandlfa166682005-12-17 21:45:17 +00001243- Implementation of PEP 341 - Unification of try/except and try/finally.
1244 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001245 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001246
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001247- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1248 now encodes backslash correctly.
1249
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001250- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1251
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001252- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001253 and long longs.
1254
Neal Norwitz67715f02005-11-09 06:59:35 +00001255- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001256 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001257 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001258
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001259- Replaced most Unicode charmap codecs with new ones using the
1260 new Unicode translate string feature in the builtin charmap
1261 codec; the codecs were created from the mapping tables available
1262 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1263 encodings now include a mapping for the Apple logo)
1264
Tim Peterse3547fd2005-12-16 23:13:57 +00001265- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001266
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001267- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001268
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001269- A new AST parser implementation was completed. The abstract
1270 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001271 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001272
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001273- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001274 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1275
Neal Norwitz708e51a2005-10-03 04:48:15 +00001276- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1277
Neal Norwitz11bd1192005-10-03 00:54:56 +00001278- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1279 Provide a warning when a directory is passed on the command line.
1280
Neal Norwitz40d37812005-10-02 01:48:49 +00001281- Fix segfault with invalid coding.
1282
1283- SF bug #772896: unknown encoding results in MemoryError.
1284
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001285- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001286 supported a __len__() method which evaluated to False when the iterator
1287 was empty.
1288
Guido van Rossum630db602005-09-20 18:49:54 +00001289- On 64-bit platforms, when __len__() returns a value that cannot be
1290 represented as a C int, raise OverflowError.
1291
Skip Montanarof8948ca2005-09-19 03:54:46 +00001292- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001293 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001294
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001295- SF bug #893549: parsing keyword arguments was broken with a few format
1296 codes.
1297
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001298- Changes donated by Elemental Security to make it work on AIX 5.3
1299 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1300 bug #105470: test_pwd fails on 64bit system (Opteron).
1301
Guido van Rossum539c6622005-09-14 17:49:54 +00001302- Changes donated by Elemental Security to make it work on HP-UX 11 on
1303 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1304
Georg Brandl4550b8d2005-08-26 06:43:52 +00001305- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001306 (fixes bug #1119418).
1307
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001308- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1309
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001310- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1311 exceptions that cause a function to exit.
1312
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001313- The implementation of set() and frozenset() was revised to use its
1314 own internal data structure. Memory consumption is reduced by 1/3
1315 and there are modest speed-ups as well. The API is unchanged.
1316
Tim Petersde7990b2005-07-17 23:45:23 +00001317- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1318
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001319- SF bug #1229429: PyObject_CallMethod failed to decrement some
1320 reference counts in some error exit cases.
1321
Tim Petersecc6e6a2005-07-10 22:30:55 +00001322- SF bug #1185883: Python's small-object memory allocator took over
1323 a block managed by the platform C library whenever a realloc specified
1324 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001325 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001326 portable way to copy data from the C-managed block into Python's
1327 small-object space without risking a memory fault. Python's small-object
1328 realloc now leaves such blocks under the control of the platform C
1329 realloc.
1330
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001331- SF bug #1232517: An overflow error was not detected properly when
1332 attempting to convert a large float to an int in os.utime().
1333
Raymond Hettinger3296e692005-06-29 23:29:56 +00001334- SF bug #1224347: hex longs now print with lowercase letters just
1335 like their int counterparts.
1336
Michael W. Hudson188d4362005-06-20 16:52:57 +00001337- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1338 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1339 interpreter states; back out that fix and do a better job (see
1340 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1341 for a longer write-up of the problem).
1342
Michael W. Hudsondf888462005-06-03 14:41:55 +00001343- SF patch #1180995: marshal now uses a binary format by default when
1344 serializing floats.
1345
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001346- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1347 the routines that promise to produce IEEE 754 binary representations
1348 of floats now simply copy bytes around.
1349
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001350- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1351 278.
1352
Brett Cannonc3647ac2005-04-26 03:45:26 +00001353- patch #1109424: int, long, float, complex, and unicode now check for the
1354 proper magic slot for type conversions when subclassed. Previously the
1355 magic slot was ignored during conversion. Semantics now match the way
1356 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001357 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001358 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001359 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001360
Barry Warsawc8d907c2005-04-19 23:43:40 +00001361- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1362 NULL, now raise an AttributeError when attempting to set or delete the
1363 attribute. Previously a TypeError was raised, but this was inconsistent
1364 with the equivalent pure-Python implementation.
1365
Michael W. Hudson774479c2005-04-18 08:46:17 +00001366- It is now safe to call PyGILState_Release() before
1367 PyEval_InitThreads() (note that if there is reason to believe there
1368 are multiple threads around you still must call PyEval_InitThreads()
1369 before using the Python API; this fix is for extension modules that
1370 have no way of knowing if Python is multi-threaded yet).
1371
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001372- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1373 disabled caused a crash.
1374
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001375- Bug #1165306: instancemethod_new allowed the creation of a method
1376 with im_class == im_self == NULL, which caused a crash when called.
1377
Tim Petersecc6e6a2005-07-10 22:30:55 +00001378- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001379 fixes the crash seen in bug #1165761
1380
Raymond Hettinger96229b12005-03-11 06:49:40 +00001381- Added two new builtins, any() and all().
1382
Brett Cannon409d8f22005-03-05 06:47:57 +00001383- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001384 (e.g., ``class C(): pass`` is no longer a syntax error).
1385 Patch #1176012 added support to the 'parser' module and 'compiler' package
1386 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001387
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001388- Patch #1115086: Support PY_LONGLONG in structmember.
1389
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001390- Bug #1155938: new style classes did not check that __init__() was
1391 returning None.
1392
Tim Petersecc6e6a2005-07-10 22:30:55 +00001393- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001394 ('\') with a specific error message.
1395
Martin v. Löwisff232d72005-03-03 09:24:38 +00001396- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1397
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001398- Bug #1124295: the __name__ attribute of file objects was
1399 inadvertently made inaccessible in restricted mode.
1400
Tim Petersecc6e6a2005-07-10 22:30:55 +00001401- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001402 an ferror() call.
1403
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001404- min() and max() now support key= arguments with the same meaning as in
1405 list.sort().
1406
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001407- The peephole optimizer now performs simple constant folding in expressions:
1408 (2+3) --> (5).
1409
Raymond Hettingera422c342005-01-11 03:03:27 +00001410- set and frozenset objects can now be marshalled. SF #1098985.
1411
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001412- Bug #1077106: Poor argument checking could cause memory corruption
1413 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001414
Jeremy Hyltonab630502005-02-04 18:44:06 +00001415- The parser did not complain about future statements in illegal
1416 positions. It once again reports a syntax error if a future
1417 statement occurs after anything other than a doc string.
1418
Neil Schemenauercf52c072005-08-12 17:34:58 +00001419- Change the %s format specifier for str objects so that it returns a
1420 unicode instance if the argument is not an instance of basestring and
1421 calling __str__ on the argument returns a unicode instance.
1422
Tim Petersf4e69282006-02-27 17:15:31 +00001423- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1424 current thread state when the auto-GIL-state machinery knows about
1425 it (since the thread state is being deleted, continuing to remember it
1426 can't help, but can hurt if another thread happens to get created with
1427 the same thread id).
1428
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001429Extension Modules
1430-----------------
1431
Georg Brandl43f08a82006-03-31 18:01:16 +00001432- Patch #1380952: fix SSL objects timing out on consecutive read()s
1433
Neal Norwitz05a45592006-03-20 06:30:08 +00001434- Patch #1309579: wait3 and wait4 were added to the posix module.
1435
Anthony Baxterfa869072006-03-20 05:21:58 +00001436- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1437 In addition, the existing ulaw code was updated.
1438
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001439- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001440 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001441
Neal Norwitz10be10c2006-03-16 06:50:13 +00001442- Everything under lib-old was removed. This includes the following modules:
1443 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001444 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001445 util, whatsound, whrandom, zmod
1446
1447- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1448
1449- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001450 is deprecated. The undocumented re.engine variable no longer exists.
1451
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001452- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1453 SS2 (single-shift 2) escape sequences correctly.
1454
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001455- The unicodedata module was updated to the 4.1 version of the Unicode
1456 database. The 3.2 version is still available as unicodedata.db_3_2_0
1457 for applications that require this specific version (such as IDNA).
1458
Neal Norwitzb62c4332006-03-04 18:35:47 +00001459- The timing module is no longer built by default. It was deprecated
1460 in PEP 4 in Python 2.0 or earlier.
1461
Guido van Rossum1968ad32006-02-25 22:38:04 +00001462- Patch 1433928: Added a new type, defaultdict, to the collections module.
1463 This uses the new __missing__ hook behavior added to dict (see above).
1464
Georg Brandldbd83392006-02-20 09:42:33 +00001465- Bug #854823: socketmodule now builds on Sun platforms even when
1466 INET_ADDRSTRLEN is not defined.
1467
Georg Brandlf4f44152006-02-18 22:29:33 +00001468- Patch #1393157: os.startfile() now has an optional argument to specify
1469 a "command verb" to invoke on the file.
1470
Neal Norwitz082b2df2006-02-07 07:04:46 +00001471- Bug #876637, prevent stack corruption when socket descriptor
1472 is larger than FD_SETSIZE.
1473
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001474- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1475 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1476 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1477
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001478- Patch #1422385: The nis module now supports access to domains other
1479 than the system default domain.
1480
Martin v. Löwis14694662006-02-03 12:54:16 +00001481- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1482 are reported, the limit on path name lengths is removed, and stat reports
1483 WindowsError now (instead of OSError).

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001619- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1620 been renamed to have only a single underscore prefix. This was done to
1621 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001622
Nick Coghlan43832302006-04-23 17:04:07 +00001623- PEP 338: new module runpy defines a run_module function to support
1624 executing modules which provide access to source code or a code object
1625 via the PEP 302 import mechanisms.
1626

1635 in attribute values.
1636
Anthony Baxterc51ee692006-04-01 00:57:31 +00001637- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001638 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001639 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001640 module will not be built.
1641
Tim Petersc17976e2006-04-01 00:26:53 +00001642- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1643 aren't officially supported here, and trying to use them will probably
1644 raise an exception some day. But dicts have been allowed, and "mostly
1645 worked", so support for them won't go away without warning.
1646
Georg Brandl338ef7d2006-03-31 18:42:16 +00001647- Bug #1445068: getpass.getpass() can now be given an explicit stream

1665
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001666- email 4.0 package now integrated. This is largely the same as the email 3.0
1667 package that was included in Python 2.3, except that PEP 8 module names are
1668 now used (e.g. mail.message instead of email.Message). The MIME classes
1669 have been moved to a subpackage (e.g. email.mime.text instead of
1670 email.MIMEText). The old names are still supported for now. Several
1671 deprecated Message methods have been removed and lots of bugs have been
1672 fixed. More details can be found in the email package documentation.
1673
Walter Dörwald40108c92006-03-27 08:15:44 +00001674- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1675 (a subclass of tuple) that provides incremental decoders and encoders
1676 (a way to use stateful codecs without the stream API). Python functions
1677 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1678 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1679 have been added.

1682 a ValueError instead of a StopIteration now (like file and cString.String do).
1683 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1684 called before (like file and StringIO.StringIO do).

1752
Neal Norwitz338e7862005-12-23 21:27:46 +00001753- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
1754 LoadError as documented, instead of IOError. For compatibility,
1755 LoadError subclasses IOError.
1756
Brett Cannon3cbd0382005-12-16 22:49:23 +00001757- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001758 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1759 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1760 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1761 Ronald L. Rivest offered this advice for Python:
1762
1763 "The consensus of researchers in this area (at least as
1764 expressed at the NIST Hash Function Workshop 10/31/05),
1765 is that SHA-256 is a good choice for the time being, but
1766 that research should continue, and other alternatives may
1767 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001768
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001769- Added a subset of Fredrik Lundh's ElementTree package. Available

Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001813 separator and do not output trailing semicolon.
Georg Brandl532efab2005-08-24 22:34:21 +00001814
Georg Brandlb9256022005-08-24 18:46:39 +00001815- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
1816 ContentTooShortException, when the actually downloaded size does not
1817 match the Content-Length header.
1818

1822 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001823 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001824

1838
Georg Brandla4a8b822005-07-15 09:13:21 +00001839- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
1840 parameter, but uses the usual "kwargs=None".
1841
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001842- textwrap now processes text chunks at O(n) speed instead of O(n**2).

1846 to W3C name (404 -> 'Not Found'). RFE #1216944.
1847
Georg Brandl9e43acf2005-07-04 17:16:07 +00001848- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1849 as this can cause problems with apps closing all file descriptors.

1862 Bug #1224621.
1863
Raymond Hettinger68c04532005-06-10 11:05:19 +00001864- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001865 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001866 the generate_tokens() function now accepts a callable argument that
1867 terminates by raising StopIteration.
1868
Georg Brandl9166e1a2005-06-04 09:20:03 +00001869- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1873
Skip Montanaro174dd222005-05-14 20:54:16 +00001874- Patch #1120353: The xmlrpclib module provides better, more transparent,

1877 class at all.
1878
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001879- distutils.commands.upload was added to support uploading distribution

1883 them to PyPI.
1884
Raymond Hettinger267b8682005-03-27 10:47:39 +00001885- decimal operator and comparison methods now return NotImplemented
1886 instead of raising a TypeError when interacting with other types. This
1887 allows other classes to implement __radd__ style methods and have them
1888 work as expected.
1889
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001890- Bug #1163325: Decimal infinities failed to hash. Attempting to
1891 hash a NaN raised an InvalidOperation instead of a TypeError.
1892
Tim Petersecc6e6a2005-07-10 22:30:55 +00001893- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1906
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001907- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1908

1927
Guido van Rossumd0641422005-02-03 15:01:24 +00001928- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1929 disables recursive traversal through instance attributes, which can
1930 be exploited in various ways.
1931
Tim Peterse3547fd2005-12-16 23:13:57 +00001932- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001933 flags on the HTTP listening socket.
1934
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001935- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1936 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1937
Fred Drakefbdeaad2006-07-29 16:56:15 +00001938- Patches #893642, #1039083: add allow_none, encoding arguments to
1939 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001940

1944
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001945- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1946
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001947- Enhancements to the csv module:
1948
1949 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001950 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001951 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001952 + Dialect parameter parsing has been re-implemented to improve error
1953 reporting.
1954 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1955 dictates.
1956 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001957 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001958 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001959 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1960 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001961 + reader now allows \r characters to be quoted (previously it only allowed
1962 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001963 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001964 + Dialect classes passed to the module are no longer instantiated by
1965 the module before being parsed (the former validation scheme required
1966 this, but the mechanism was unreliable).
1967 + The dialect registry now contains instances of the internal
1968 C-coded dialect type, rather than references to python objects.
1969 + the internal c-coded dialect type is now immutable.
1970 + register_dialect now accepts the same keyword dialect specifications
1971 as the reader and writer, allowing the user to register dialects
1972 without first creating a dialect class.
1973 + a configurable limit to the size of parsed fields has been added -
1974 previously, an unmatched quote character could result in the entire
1975 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001976 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001977 the parser field size limit (returning the former limit). The initial
1978 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001979 + A line_num attribute has been added to the reader object, which tracks
1980 the number of lines read from the source iterator. This is not
1981 the same as the number of records returned, as records can span
1982 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001983 + reader and writer objects were not being registered with the cyclic-GC.
1984 This has been fixed.
1985
Brett Cannone6539c42005-01-08 02:43:53 +00001986- _DummyThread objects in the threading module now delete self.__block that is
1987 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1988 lock primitives tend to be limited in number and thus should not be wasted on
1989 a _DummyThread object. Fixes bug #1089632.
1990
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001991- The imghdr module now detects Exif files.
1992
Raymond Hettinger6065d322004-12-20 23:51:53 +00001993- StringIO.truncate() now correctly adjusts the size attribute.
1994 (Bug #951915).
1995
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001996- locale.py now uses an updated locale alias table (built using
1997 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1998 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001999 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002000
Raymond Hettinger3557f422004-12-07 12:02:02 +00002001- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2002
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002003- the pickle module no longer accepts the deprecated None option in the
2004 args tuple returned by __reduce__().
2005
Brett Cannon84667c02004-12-07 03:25:18 +00002006- optparse now optionally imports gettext. This allows its use in setup.py.
2007
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002008- the pickle module no longer uses the deprecated bin parameter.
2009

2015
Raymond Hettinger664347b2004-12-04 21:21:53 +00002016- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2017 extended or overridden by subclasses. Formerly, the subclassed method would
2018 be ignored by the rest of the module. (Bug #1078905).
2019
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002020- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002021 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002022
Walter Dörwald36733692004-12-22 12:50:50 +00002023- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2024 once when a size argument is given. This prevents a buffer overflow in the
2025 tokenizer with very long source lines.
2026
Barry Warsaw538561e2006-01-01 21:48:54 +00002027- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2028 immediately after creating the object, without any intervening
2029 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002030
Skip Montanaro05885812005-01-16 20:48:27 +00002031- The reconvert.quote function can now emit triple-quoted strings. The
2032 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002033
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002034- ``UserString.MutableString`` now supports negative indices in
2035 ``__setitem__`` and ``__delitem__``
2036
Greg Ward40407942005-03-05 02:53:17 +00002037- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2038 correctly.
2039
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002040- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2041 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2042 character even if the user has passed a size parameter to get a proper
2043 line ending. Remove the special handling of a "\r\n" that has been split
2044 between two lines.
2045
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002046- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2047 about illegal code points. The codec now supports PEP 293 style error
2048 handlers.
2049
Walter Dörwald78a78b02005-09-01 12:04:29 +00002050- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002051 from the input stream, so that the output is a byte string in the correct
2052 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002053
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002054- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2055 considering it exactly like a '*'.
2056
Walter Dörwald007f8df2005-10-09 19:42:27 +00002057- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2058 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002059
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002060- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2061
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002062- Patch #1413711: Certain patterns of differences were making difflib
2063 touch the recursion limit.
2064
Walter Dörwald58917a62006-03-31 15:26:22 +00002065- Bug #947906: An object oriented interface has been added to the calendar
2066 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002067 called as a script (e.g. via ``python -mcalendar``). Localized month and
2068 weekday names can be ouput (even if an exotic encoding is used) using
2069 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002071Build
2072-----
2073
Neal Norwitz602d3392006-03-31 08:21:40 +00002074- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2075 by using -mieee gcc option.
2076

2078
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002079- Build support for Win64-AMD64 was added.
2080
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002081- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2082
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002083- Patch #881820: look for openpty and forkpty also in libbsd.
2084
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002085- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2086 The zlib module is now builtin on Windows.
2087
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002088- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2089
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002090- Bug #1189330: configure did not correctly determine the necessary
2091 value of LINKCC if python was built with GCC 4.0.
2092
Trent Mick8321b422005-07-26 02:29:21 +00002093- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2094 vulnerability in zlib 1.2.1 and 1.2.2.
2095
Brett Cannon08cd5982005-04-24 22:26:38 +00002096- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2097 flags that change binary compatibility. Changes were also made to
2098 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002099 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002100
Bob Ippolitoed233462005-03-29 13:47:59 +00002101- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2102 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2103 no longer exists). This configure patch makes things right.
2104
Martin v. Löwise2713be2005-03-08 15:03:08 +00002105- Bug #1158607: Build with --disable-unicode again.
2106
Brett Cannon46d96232005-02-16 00:07:19 +00002107- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2108 defined. Discovered as a result of not being able to build on OS X.
2109
Brett Cannon516592f2004-12-07 00:42:59 +00002110- setup.py now uses the directories specified in LDFLAGS using the -L option
2111 and in CPPFLAGS using the -I option for adding library and include
2112 directories, respectively, for compiling extension modules against. This has
2113 led to the core being compiled using the values in CPPFLAGS. It also removes
2114 the need for the special-casing of both DarwinPorts and Fink for darwin since
2115 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2116 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2117 Fink, ``-I/opt/local/include`` for DarwinPorts).
2118
Brett Cannon43802422005-02-10 20:48:03 +00002119- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2120 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2121 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2122 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002124C API
2125-----
2126
Tim Petersc9d78aa2006-03-26 23:27:58 +00002127- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2128 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2129 is obtained via the ``PyObject_`` family, it must be released via the
2130 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2131 always been officially true, but when Python's small-object allocator was
2132 introduced, an attempt was made to cater to a few extension modules
2133 discovered at the time that obtained memory via ``PyObject_New`` but
2134 released it via ``PyMem_DEL``. It's years later, and if such code still
2135 exists it will fail now (probably with segfaults, but calling wrong
2136 low-level memory management functions can yield many symptoms).
2137
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002138- Added a C API for set and frozenset objects.
2139
Raymond Hettinger66517482004-12-03 11:45:13 +00002140- Removed PyRange_New().
2141
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002142- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2143 mapping argument now. This string is used as a mapping table. Byte values
2144 greater than the length of the string and 0xFFFE are treated as undefined
2145 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002151- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002152
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002153- Patch #1276356: New resource "urlfetch" is implemented. This enables
2154 even impatient people to run tests that require remote files.
