27
Neal Norwitzd3da7d32006-09-05 01:54:06 +000028- Patch #1546288: fix seg fault in dict_equal due to ref counting bug.
29
Neal Norwitz29a5fdb2006-09-05 02:21:38 +000030- The return tuple from str.rpartition(sep) is (tail, sep, head) where
31 head is the original string if sep was not found.
32
Neal Norwitz3b3aae02006-09-05 03:56:01 +000033- Bug #1520864: unpacking singleton tuples in list comprehensions and
34 generator expressions (x for x, in ... ) works again. Fixing this problem
35 required changing the .pyc magic number. This means that .pyc files
36 generated before 2.5c2 will be regenerated.

98
Marc-André Lemburg040f76b2006-08-14 10:55:19 +000099- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000100 compared equal or unequal to a string and a UnicodeDecodeError
101 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000102
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000103 Instead, the equal (==) and unequal (!=) comparison operators will
104 now issue a UnicodeWarning and interpret the two objects as
105 unequal. The UnicodeWarning can be filtered as desired using
106 the warning framework, e.g. silenced completely, turned into an
107 exception, logged, etc.
108
109 Note that compare operators other than equal and unequal will still
110 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000111
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000112- Fix segfault when doing string formatting on subclasses of long.
113
114- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
115 with new-style classes.
116
117- Fix bug related to __len__ functions returning negative values with
118 classic classes.
119
120- Patch #1538606, Fix __index__() clipping. There were some problems
121 discovered with the API and how integers that didn't fit into Py_ssize_t
122 were handled. This patch attempts to provide enough alternatives
123 to effectively use __index__.
124
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000125- Bug #1536021: __hash__ may now return long int; the final hash
126 value is obtained by invoking hash on the long int.
127
Thomas Hellerab1049c2006-08-08 17:37:00 +0000128- Bug #1536786: buffer comparison could emit a RuntimeWarning.
129
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000130- Bug #1535165: fixed a segfault in input() and raw_input() when
131 sys.stdin is closed.
132
Thomas Heller74d36f02006-08-04 18:17:40 +0000133- On Windows, the PyErr_Warn function is now exported from
134 the Python dll again.
135
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000136- Bug #1191458: tracing over for loops now produces a line event
137 on each iteration. Fixing this problem required changing the .pyc
138 magic number. This means that .pyc files generated before 2.5c1
139 will be regenerated.
140
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000141- Bug #1333982: string/number constants were inappropriately stored
142 in the byte code and co_consts even if they were not used, ie
143 immediately popped off the stack.
144
Georg Brandle9462c72006-08-04 18:03:37 +0000145- Fixed a reference-counting problem in property().

149-------
150
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000151- Fix a bug in the ``compiler`` package that caused invalid code to be
152 generated for generator expressions.
153
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000154- The distutils version has been changed to 2.5.0. The change to
155 keep it programmatically in sync with the Python version running
156 the code (introduced in 2.5b3) has been reverted. It will continue
157 to be maintained manually as static string literal.
158
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000159- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000160 and this cannot be converted to the required C type, an exception is
161 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000162 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000163
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000164- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000165 an exception.
166
Tim Peterscbdd3502006-09-05 01:47:53 +0000167- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000168 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000169 workarounds for clocks with low resolution, to stop the code yielding
170 duplicate UUIDs.
171
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000172- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
173 before raising SystemExit, allowing IDLE to honor quit() and exit().
174
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000175- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
176
Georg Brandl7a1af772006-08-14 21:55:28 +0000177- Patch #1536071: trace.py should now find the full module name of a
178 file correctly even on Windows.
179
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000180- logging's atexit hook now runs even if the rest of the module has
181 already been cleaned up.
182
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000183- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000184
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000185- Bug #1531405, format_exception no longer raises an exception if
186 str(exception) raised an exception.
187
Neil Schemenauer06ded092006-08-04 16:20:30 +0000188- Fix a bug in the ``compiler`` package that caused invalid code to be
189 generated for nested functions.

196
Georg Brandl3335a7a2006-08-14 21:42:55 +0000197- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
198 raises the correct exceptions.
199
Thomas Heller1ce433e2006-08-14 16:20:04 +0000200- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
201 '-no-stack-protector' compiler flag for OpenBSD has been removed.
202
Thomas Heller86720042006-08-14 11:17:48 +0000203- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
204 uses the _as_parameter_ attribute when objects are passed to foreign
205 function calls. The ctypes version number was changed to 1.0.1.
206
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000207- Bug #1530559, struct.pack raises TypeError where it used to convert.
208 Passing float arguments to struct.pack when integers are expected
209 now triggers a DeprecationWarning.

Neal Norwitza1f10902006-07-12 07:28:29 +0000258
259Core and builtins
260-----------------
261
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000262- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000263 returned a long (see PEP 353).
264
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000265- Bug #1515471: string.replace() accepts character buffers again.
266
Neal Norwitz07aadb12006-07-30 06:55:48 +0000267- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
268 This provides the proper warning for struct.pack().
269 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
270
Neal Norwitz0d62a062006-07-30 06:53:31 +0000271- Patch #1531113: Fix augmented assignment with yield expressions.
272 Also fix a SystemError when trying to assign to yield expressions.
273
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000274- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
275 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
276 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
277 excessive filesystem operations during imports.
278
Tim Petersbc24eee2006-07-27 01:14:53 +0000279- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
280 operations on signed longs that are formally undefined by C.
281 Unfortunately, at least one compiler now cares about that, so complicated
282 the code to make that compiler happy again.
283
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000284- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
285
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000286- Patch #1232023: Stop including current directory in search
287 path on Windows.
288
Neal Norwitze1fdb322006-07-21 05:32:28 +0000289- Fix some potential crashes found with failmalloc.
290
Neal Norwitze7563102006-07-17 01:00:16 +0000291- Fix warnings reported by Klocwork's static analysis tool.
292
Neal Norwitz84be93b2006-07-16 01:50:38 +0000293- Bug #1512814, Fix incorrect lineno's when code within a function
294 had more than 255 blank lines.
295
Georg Brandl9dceedb2006-07-12 15:31:17 +0000296- Patch #1521179: Python now accepts the standard options ``--help`` and
297 ``--version`` as well as ``/?`` on Windows.
298
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000299- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000300 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000301 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000302
Tim Peters112aad32006-07-19 00:03:19 +0000303- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000304 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000305 new ``sys._current_frames()`` returns a dictionary with one entry,
306 mapping the faux "thread id" 0 to the current frame.
307
Ronald Oussoren3075e162006-07-25 20:28:55 +0000308- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

Martin v. Löwis961b91b2006-08-02 13:53:55 +0000314- Correction of patch #1455898: In the mbcs decoder, set final=False
315 for stream decoder, but final=True for the decode function.
316
Georg Brandl07fec3a2006-08-01 18:49:24 +0000317- os.urandom no longer masks unrelated exceptions like SystemExit or
318 KeyboardInterrupt.
319
Tim Peters4643c2f2006-08-10 22:45:34 +0000320- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000321 shutil.copytree on Windows
322
Georg Brandle34ac7c2006-07-30 11:07:23 +0000323- Bug #1002398: The documentation for os.path.sameopenfile now correctly
324 refers to file descriptors, not file objects.
325
Tim Peterscbdd3502006-09-05 01:47:53 +0000326- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000327 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000328 #1513611, and probably others.
329
Georg Brandledd9b0d2006-07-29 09:33:26 +0000330- Bug #1441397: The compiler module now recognizes module and function
331 docstrings correctly as it did in Python 2.4.
332
Tim Peters6f681472006-07-27 23:44:37 +0000333- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
334 lost that tests are sorted by name before being run. This rarely
335 matters for well-written tests, but can create baffling symptoms if
336 side effects from one test to the next affect outcomes. ``DocTestFinder``
337 has been changed to sort the list of tests it returns.
338
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000339- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000340 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000341
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000342- Bug #978833: Really close underlying socket in _socketobject.close.
343
Georg Brandldb232dc2006-08-20 13:15:43 +0000344- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
345 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000346
Georg Brandlcf0c1722006-07-26 07:23:32 +0000347- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
348 to recursive calls and call it with the failing package name.
349
Martin v. Löwis0b483032006-07-25 09:53:12 +0000350- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
351
Georg Brandlc13c34c2006-07-24 14:09:56 +0000352- Patch #1515343: Fix printing of deprecated string exceptions with a
353 value in the traceback module.
354
Greg Ward48fae7a2006-07-23 16:05:51 +0000355- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
356
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000357- Patch #1524429: Use repr() instead of backticks in Tkinter again.
358
Brett Cannoncaebe222006-07-18 04:41:36 +0000359- Bug #1520914: Change time.strftime() to accept a zero for any position in its
360 argument tuple. For arguments where zero is illegal, the value is forced to
361 the minimum value that is correct. This is to support an undocumented but
362 common way people used to fill in inconsequential information in the time
363 tuple pre-2.4.
364
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000365- Patch #1220874: Update the binhex module for Mach-O.
366
Barry Warsawb110bad2006-07-21 14:51:07 +0000367- The email package has improved RFC 2231 support, specifically for
368 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
369 (name*0=<blah>) parameter continuations. This may change the types of
370 values returned from email.message.Message.get_param() and friends.
371 Specifically in some cases where non-encoded continuations were used,
372 get_param() used to return a 3-tuple of (None, None, string) whereas now it
373 will just return the string (since non-encoded continuations don't have
374 charset and language parts).
375
376 Also, whereas % values were decoded in all parameter continuations, they are
377 now only decoded in encoded parameter parts.
378
Ronald Oussoren3075e162006-07-25 20:28:55 +0000379- Bug #1517990: IDLE keybindings on MacOS X now work correctly
380
381- Bug #1517996: IDLE now longer shows the default Tk menu when a
382 path browser, class browser or debugger is the frontmost window on MacOS X
383
Barry Warsaw00decd72006-07-27 23:43:15 +0000384- Patch #1520294: Support for getset and member descriptors in types.py,
385 inspect.py, and pydoc.py. Specifically, this allows for querying the type
386 of an object against these built-in types and more importantly, for getting
387 their docstrings printed in the interactive interpreter's help() function.

391-----------------
392
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000393- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
394 a socket operation on a socket with a timeout, the exception will be
395 caught correctly. Previously, the exception was not caught.
396
Thomas Heller1393d6a2006-07-28 21:43:20 +0000397- Patch #1529514: The _ctypes extension is now compiled on more
398 openbsd target platforms.
399
Tim Peters9cab5932006-07-28 00:30:00 +0000400- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
401 a memory leak, affecting pickles and deep copies.
402
Tim Petersbc24eee2006-07-27 01:14:53 +0000403- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000404 Paul Eggert.
405
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000406- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
407
Thomas Hellerce049a02006-07-14 17:51:14 +0000408- Patch #1521817: Index range checking on ctypes arrays containing
409 exactly one element enabled again. This allows iterating over these
410 arrays, without the need to check the array size before.
411
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000412- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000413 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000414 /dev/null in certain cases; this is now fixed.
415
Thomas Heller47d7a062006-07-12 08:43:47 +0000416- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
417 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000418
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000419- Because of a misspelled preprocessor symbol, ctypes was always
420 compiled without thread support; this is now fixed.
421
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000422- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
423 methods now allow their database parameter to be None as the
424 sleepycat API allows.
425
Matt Flemingec926502006-07-28 11:27:27 +0000426- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
427 bluetooth API compared with Linux and FreeBSD.
428
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000429Tests
430-----
431
432- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
433 how long the test file should take to play. Now accepts taking 2.93 secs
434 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
435
Georg Brandl4793aa32006-07-28 18:31:39 +0000436- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
437 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
438 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000439
Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000440Build
441-----
442
443- Bug #1439538: Drop usage of test -e in configure as it is not portable.
444
Ronald Oussoren26cad082006-08-01 21:00:57 +0000445Mac
446---
447
448- PythonLauncher now works correctly when the path to the script contains
449 characters that are treated specially by the shell (such as quotes).
450
451- Bug #1527397: PythonLauncher now launches scripts with the working directory
452 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000453 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000454 expect.

462Core and builtins
463-----------------
464
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000465- Bug #1441486: The literal representation of -(sys.maxint - 1)
466 again evaluates to a int object, not a long.
467
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000468- Bug #1501934: The scope of global variables that are locally assigned
469 using augmented assignment is now correctly determined.
470
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000471- Bug #927248: Recursive method-wrapper objects can now safely
472 be released.
473
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000474- Bug #1417699: Reject locale-specific decimal point in float()
475 and atof().
476
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000477- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
478 omit a default "error" argument for NULL pointer. This allows
479 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000480
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000481- Bug #1519018: 'as' is now validated properly in import statements.
482
Neal Norwitz28746ab2006-07-09 22:14:42 +0000483- On 64 bit systems, int literals that use less than 64 bits are
484 now ints rather than longs.
485
Neal Norwitzed657552006-07-10 00:04:44 +0000486- Bug #1512814, Fix incorrect lineno's when code at module scope
487 started after line 256.
488
Tim Peters32a83612006-07-10 21:08:24 +0000489- New function ``sys._current_frames()`` returns a dict mapping thread
490 id to topmost thread stack frame. This is for expert use, and is
491 especially useful for debugging application deadlocks. The functionality
492 was previously available in Fazal Majid's ``threadframe`` extension
493 module, but it wasn't possible to do this in a wholly threadsafe way from
494 an extension.

511
Thomas Woutersadd19112006-07-05 11:03:49 +0000512- string.Template() now correctly handles tuple-values. Previously,
513 multi-value tuples would raise an exception and single-value tuples would
514 be treated as the value they contain, instead.
515
Martin v. Löwisede77f52006-07-03 13:01:35 +0000516- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

536
537- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
538 sgmllib ('[' and ']' were not accepted).

Georg Brandl1be63af2006-06-28 20:23:25 +0000540- Fix a bug in the turtle module's end_fill function.
541
Brett Cannon53ab5b72006-06-22 16:49:14 +0000542- Bug #1510580: The 'warnings' module improperly required that a Warning
543 category be either a types.ClassType and a subclass of Warning. The proper
544 check is just that it is a subclass with Warning as the documentation states.
545
Georg Brandlad29e632006-06-21 17:45:17 +0000546- The compiler module now correctly compiles the new try-except-finally
547 statement (bug #1509132).
548
Neal Norwitz60373cd2006-06-22 06:30:50 +0000549- The wsgiref package is now installed properly on Unix.
550
Vinay Sajip28e57612006-07-01 10:45:20 +0000551- A bug was fixed in logging.config.fileConfig() which caused a crash on
552 shutdown when fileConfig() was called multiple times.
553
Gerhard Häring762fbd32006-07-02 17:48:30 +0000554- The sqlite3 module did cut off data from the SQLite database at the first
555 null character before sending it to a custom converter. This has been fixed
556 now.

559-----------------
560
Tim Peters112aad32006-07-19 00:03:19 +0000561- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
562 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
563 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000564
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000565- Assigning None to pointer type fields in ctypes structures possible
566 overwrote the wrong fields, this is fixed now.
567
568- Fixed a segfault in _ctypes when ctypes.wintypes were imported
569 on non-Windows platforms.
570
571- Bug #1518190: The ctypes.c_void_p constructor now accepts any
572 integer or long, without range checking.
573
574- Patch #1517790: It is now possible to use custom objects in the ctypes
575 foreign function argtypes sequence as long as they provide a from_param
576 method, no longer is it required that the object is a ctypes type.
577
578- The '_ctypes' extension module now works when Python is configured
579 with the --without-threads option.
580
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000581- Bug #1513646: os.access on Windows now correctly determines write

596
Tim Peters32a83612006-07-10 21:08:24 +0000597- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000598 Previously, the slight difference could cause compilation errors of the
599 'zlib' module on systems with more than one version of zlib.
600
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000601- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +0000631
632Core and builtins
633-----------------
634
Georg Brandla56b9152006-06-19 06:35:54 +0000635- Patch #1507676: Error messages returned by invalid abstract object operations
636 (such as iterating over an integer) have been improved and now include the
637 type of the offending object to help with debugging.
638
Brett Cannonea3912b2006-06-13 21:46:41 +0000639- Bug #992017: A classic class that defined a __coerce__() method that returned
640 its arguments swapped would infinitely recurse and segfault the interpreter.
641
Neal Norwitz909eb122006-06-12 02:13:21 +0000642- Fix the socket tests so they can be run concurrently.
643
Neal Norwitzb9845e72006-06-12 02:11:18 +0000644- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000645 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000646
Brett Cannon22565aa2006-06-09 22:31:23 +0000647- Bug #532646: object.__call__() will continue looking for the __call__
648 attribute on objects until one without one is found. This leads to recursion
649 when you take a class and set its __call__ attribute to an instance of the
650 class. Originally fixed for classic classes, but this fix is for new-style.
651 Removes the infinite_rec_3 crasher.
652
Georg Brandl24250812006-06-09 18:45:48 +0000653- The string and unicode methods startswith() and endswith() now accept
654 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
655
Brett Cannonde3b0522006-06-08 17:00:45 +0000656- Buffer objects, at the C level, never used the char buffer
657 implementation even when the char buffer for the wrapped object was
658 explicitly requested (originally returned the read or write buffer).
659 Now a TypeError is raised if the char buffer is not present but is
660 requested.
661
Georg Brandlddbaa662006-06-04 21:56:52 +0000662- Patch #1346214: Statements like "if 0: suite" are now again optimized
663 away like they were in Python 2.4.
664
Georg Brandlb7c8f542006-05-27 12:30:25 +0000665- Builtin exceptions are now full-blown new-style classes instead of
666 instances pretending to be classes, which speeds up exception handling
667 by about 80% in comparison to 2.5a2.
668
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000669- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
670 Unicode 4.1.
671
Georg Brandlf4ef1162006-05-26 18:03:31 +0000672- Patch #921466: sys.path_importer_cache is now used to cache valid and
673 invalid file paths for the built-in import machinery which leads to
674 fewer open calls on startup.
675
Tim Peters696cf432006-05-24 21:10:40 +0000676- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
677 of-2 bases. The largest speedup is for inputs with about 1000 decimal
678 digits. Conversion from non-power-of-2 bases remains quadratic-time in
679 the number of input digits (it was and remains linear-time for bases
680 2, 4, 8, 16 and 32).
681
Tim Petersb713ec22006-05-23 18:45:30 +0000682- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
683 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
684 an integer close to ``sys.maxint``. This was repaired by patch
685 #1335972, which also gives a nice speedup.
686
Richard Jonescebbefc2006-05-23 18:28:17 +0000687- Patch #1337051: reduced size of frame objects.
688
689- PyErr_NewException now accepts a tuple of base classes as its
690 "base" parameter.
691
Richard Jones7c88dcc2006-05-23 10:37:38 +0000692- Patch #876206: function call speedup by retaining allocated frame
693 objects.
694
Georg Brandl7b90e162006-05-18 07:01:27 +0000695- Bug #1462152: file() now checks more thoroughly for invalid mode
696 strings and removes a possible "U" before passing the mode to the
697 C library function.
698
Neal Norwitz1004a532006-05-15 07:17:23 +0000699- Patch #1488312, Fix memory alignment problem on SPARC in unicode
700
Neal Norwitz373f0a72006-05-15 07:04:36 +0000701- Bug #1487966: Fix SystemError with conditional expression in assignment
702
Martin v. Löwis879768d2006-05-11 13:28:43 +0000703- WindowsError now has two error code attributes: errno, which carries
704 the error values from errno.h, and winerror, which carries the error
705 values from winerror.h. Previous versions put the winerror.h values
706 (from GetLastError()) into the errno attribute.
707
Martin v. Löwis77736712006-05-04 05:51:03 +0000708- Patch #1475845: Raise IndentationError for unexpected indent.
709
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000710- Patch #1479181: split open() and file() from being aliases for each other.
711
Tim Peters44bd9862006-06-01 13:49:23 +0000712- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
713 methods were always silently ignored by dictionaries when comparing keys.
714 They are now passed through (except when using the C API function
715 ``PyDict_GetItem()``, whose semantics did not change).
716
717- Bug #1456209: In some obscure cases it was possible for a class with a
718 custom ``__eq__()`` method to confuse dict internals when class instances
719 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
720 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000722Extension Modules
723-----------------
724
Trent Mick960a3f82006-06-28 20:30:41 +0000725- Bug #1295808: expat symbols should be namespaced in pyexpat
726
727- Patch #1462338: Upgrade pyexpat to expat 2.0.0
728
Brett Cannon6ee7d012006-06-08 16:23:04 +0000729- Change binascii.hexlify to accept a read-only buffer instead of only a char
730 buffer and actually follow its documentation.
731
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000732- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
733
Nick Coghlanc649ec52006-05-29 12:43:05 +0000734- Patch #1478788 (modified version): The functional extension module has
735 been renamed to _functools and a functools Python wrapper module added.
736 This provides a home for additional function related utilities that are
737 not specifically about functional programming. See PEP 309.
738
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000739- Patch #1493701: performance enhancements for struct module.
740
Georg Brandl378d5922006-05-17 14:26:50 +0000741- Patch #1490224: time.altzone is now set correctly on Cygwin.
742
Georg Brandl8d3342b2006-05-16 07:38:27 +0000743- Patch #1435422: zlib's compress and decompress objects now have a
744 copy() method.
745
Andrew MacIntyre92913322006-06-13 15:04:24 +0000746- Patch #1454481: thread stack size is now tunable at runtime for thread
747 enabled builds on Windows and systems with Posix threads support.
748
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000749- On Win32, os.listdir now supports arbitrarily-long Unicode path names
750 (up to the system limit of 32K characters).
751
752- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
753 As a result, these functions now raise WindowsError instead of OSError.
754
Tim Peters7a822da2006-05-25 21:50:17 +0000755- ``time.clock()`` on Win64 should use the high-performance Windows
756 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
757 Windows platforms).
758
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000759- Calling Tk_Init twice is refused if the first call failed as that
760 may deadlock.
761
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000762- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
763 accept it without potentially using an uninitialized pointer.
764
765- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
766 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
767 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000768
Gregory P. Smith372b5832006-06-05 18:48:21 +0000769- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000770 [pybsddb project SF patch number 1466734]
771
Gregory P. Smith372b5832006-06-05 18:48:21 +0000772- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
773 parameter is supplied. [SF pybsddb bug #1477863]
774
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000775- bsddb: the __len__ method of a DB object has been fixed to return correct
776 results. It could previously incorrectly return 0 in some cases.
777 Fixes SF bug 1493322 (pybsddb bug 1184012).
778
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000779- bsddb: the bsddb.dbtables Modify method now raises the proper error and
780 aborts the db transaction safely when a modifier callback fails.
781 Fixes SF python patch/bug #1408584.
782
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000783- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000784 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000785 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
786 database calls that would previously deadlock. [SF python bug #775414]
787
Vinay Sajip28e57612006-07-01 10:45:20 +0000788- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000789
Walter Dörwald4994d952006-06-19 08:07:50 +0000790- Patch #1506645: add Python wrappers for the curses functions
791 is_term_resized, resize_term and resizeterm.

795
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000796- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
797 functions.
798
Martin v. Löwis3798da02006-06-17 18:44:27 +0000799- Patch #812986: Update turtle output even if not tracing.
800
Vinay Sajip28e57612006-07-01 10:45:20 +0000801- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000802 Tkinter.BaseWidget.
803
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000804- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
805
Martin v. Löwis337487e2006-06-17 09:15:14 +0000806- Patch #763580: Add name and value arguments to Tkinter variable
807 classes.
808
Georg Brandl83cc0d02006-06-14 08:50:03 +0000809- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
810 mime.types file for determining MIME types.
811
Georg Brandl2605ca82006-06-14 06:08:31 +0000812- Bug #1339007: Shelf objects now don't raise an exception in their
813 __del__ method when initialization failed.
814
Martin v. Löwisd8251432006-06-14 05:21:04 +0000815- Patch #1455898: The MBCS codec now supports the incremental mode for
816 double-byte encodings.
817
Tim Peters43898b42006-06-14 04:09:25 +0000818- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
819 guarantee that adjacent triples in the return list always describe
820 non-adjacent blocks. Previously, a pair of matching blocks could end
821 up being described by multiple adjacent triples that formed a partition
822 of the matching pair.
823
Greg Ward0e0c9f42006-06-11 16:24:11 +0000824- Bug #1498146: fix optparse to handle Unicode strings in option help,
825 description, and epilog.
826
Greg Wardd1c797e2006-06-11 14:42:41 +0000827- Bug #1366250: minor optparse documentation error.
828
Greg Ward7f547402006-06-11 00:40:49 +0000829- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
830 clarify docs.
831
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000832- The wsgiref package has been added to the standard library.
833
Nick Coghlan676725d2006-06-08 13:54:49 +0000834- The functions update_wrapper() and wraps() have been added to the functools
835 module. These make it easier to copy relevant metadata from the original
836 function when writing wrapper functions.
837
Tim Petersd6a9eef2006-06-05 01:48:21 +0000838- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
839 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000840
Martin v. Löwis3f767792006-06-04 19:36:28 +0000841- Patch #1359618: Speed up charmap encoder by using a trie structure
842 for lookup.
843
Tim Petersd609b1a2006-06-02 23:22:51 +0000844- The functions in the ``pprint`` module now sort dictionaries by key
845 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
846 if and only if its display required more than one line, although that
847 wasn't documented. The new behavior increases predictability; e.g.,
848 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
849
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000850- Patch #1497027: try HTTP digest auth before basic auth in urllib2
851 (thanks for J. J. Lee).
852
Georg Brandl2b330372006-05-28 20:23:12 +0000853- Patch #1496206: improve urllib2 handling of passwords with respect to
854 default HTTP and HTTPS ports.
855
George Yoshidaf3c65de2006-05-28 16:39:09 +0000856- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
857
Bob Ippolito7298f272006-05-23 18:43:47 +0000858- Patch #1281707: speed up gzip.readline.
859
Georg Brandlb89316f2006-05-17 15:51:16 +0000860- Patch #1180296: Two new functions were added to the locale module:
861 format_string() to get the effect of "format % items" but locale-aware,
862 and currency() to format a monetary number with currency sign.
863
Georg Brandle3a25832006-05-17 14:56:04 +0000864- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
865 and several features added, such as speed and geometry control.
866
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000867- Patch #1488881: add support for external file objects in bz2 compressed
868 tarfiles.
869
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000870- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
871 stdout arguments, making it possible to redirect input and output
872 for remote debugging.
873
874- Patch #1484695: Update the tarfile module to version 0.8. This fixes
875 a couple of issues, notably handling of long file names using the
876 GNU LONGNAME extension.
877
878- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
879 new flag when ``name`` is already the name of an option flag.
880
881- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
882 package.
883
884- Patch #1472854: make the rlcompleter.Completer class usable on non-
885 UNIX platforms.
886
887- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
888
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000889- Bug #1472827: correctly escape newlines and tabs in attribute values in

Martin v. Löwis45294a92006-04-18 06:24:08 +0000937- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
938
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000939- All uses of PyStructSequence_InitType have been changed to initialize
940 the type objects only once, even if the interpreter is initialized
941 multiple times.
942
Neal Norwitz61546162006-04-14 05:20:28 +0000943- Bug #1454485, array.array('u') could crash the interpreter. This was
944 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
945 to unicode when it didn't make sense. 'u#' now requires a unicode string.
946
947- Py_UNICODE is unsigned. It was always documented as unsigned, but
948 due to a bug had a signed value in previous versions.
949
Tim Peters3a5e8b12006-04-11 01:44:07 +0000950- Patch #837242: ``id()`` of any Python object always gives a positive
951 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
952 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000953 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000954 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000955
Tim Peters3a5e8b12006-04-11 01:44:07 +0000956 def __hash__(self):
957 return id(self) # WRONG
958
959 because a hash result must be a (short) Python int but it was always
960 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000961 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000962 was always usable as a hash value before this patch. That's no longer
963 necessarily so.
964
965- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000966 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000967 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000968 #1454844)
969
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000970- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
971 involving generators that have paused outside of any ``try`` or ``with``
972 blocks. (In 2.5a1, a paused generator that was part of a reference
973 cycle could not be garbage collected, regardless of whether it was
974 paused in a ``try`` or ``with`` block.)

980 is a macro.
981
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000982- Bug #1467952: os.listdir() now correctly raises an error if readdir()
983 fails with an error condition.
984
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000985- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
986
987- Bug #1117761: bsddb.*open() no longer raises an exception when using
988 the cachesize parameter.
989
990- Bug #1149413: bsddb.*open() no longer raises an exception when using
991 a temporary db (file=None) with the 'n' flag to truncate on open.
992
993- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
994 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000995
Armin Rigoa9017c32006-04-19 11:50:27 +0000996- Patch #1062014: AF_UNIX sockets under Linux have a special
997 abstract namespace that is now fully supported.

1000-------
1001
Peter Astrand7d1d4362006-07-14 14:04:45 +00001002- Bug #1223937: subprocess.CalledProcessError reports the exit status
1003 of the process using the returncode attribute, instead of
1004 abusing errno.
1005
Tim Peters711bf302006-04-25 03:31:36 +00001006- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1007 a doctest to be skipped (the code is not run, and the expected output
1008 or exception is ignored).
1009
Nick Coghlanda2268f2006-04-24 04:37:15 +00001010- Fixed contextlib.nested to cope with exceptions being raised and
1011 caught inside exit handlers.
1012
Greg Wardab05edc2006-04-23 03:47:58 +00001013- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1014 hex, octal, or binary; add ``append_const`` action; keep going if
1015 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1016 added ``epilog`` for better help generation).
1017
Tim Peters21fbd572006-04-21 21:18:10 +00001018- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1019 called from a thread spawned as a side effect of importing a module.
1020
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001021- The pydoc module now supports documenting packages contained in
1022 .zip or .egg files.
1023
1024- The pkgutil module now has several new utility functions, such
1025 as ``walk_packages()`` to support working with packages that are either
1026 in the filesystem or zip files.
1027
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001028- The mailbox module can now modify and delete messages from
1029 mailboxes, in addition to simply reading them. Thanks to Gregory
1030 K. Johnson for writing the code, and to the 2005 Google Summer of
1031 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001032
Tim Petersc7605f22006-04-17 21:12:33 +00001033- The ``__del__`` method of class ``local`` in module ``_threading_local``
1034 returned before accomplishing any of its intended cleanup.

1041
Anthony Baxtere29002c2006-04-12 12:07:31 +00001042- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1043 Windows. Bug #1469163.
1044
Phillip J. Eby47032112006-04-11 01:07:43 +00001045- The warnings, linecache, inspect, traceback, site, and doctest modules
1046 were updated to work correctly with modules imported from zipfiles or
1047 via other PEP 302 __loader__ objects.
1048
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001049- Patch #1467770: Reduce usage of subprocess._active to processes which

1055
Skip Montanaro262fb922006-04-21 02:31:07 +00001056- The pstats.Stats class accepts an optional stream keyword argument to
1057 direct output to an alternate file-like object.
1058
Anthony Baxter51bcb682006-04-05 14:51:42 +00001059Build
1060-----
1061
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001062- The Makefile now has a reindent target, which runs reindent.py on
1063 the library.
1064
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001065- Patch #1470875: Building Python with MS Free Compiler
1066

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001068
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001069- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1070 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001071 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001072 CXX from --with-cxx-main, see description in README.
1073
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001074- Patch #1429775: Link extension modules with the shared libpython.
1075
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001076- Fixed a libffi build problem on MIPS systems.
1077
Tim Peters8931ff12006-05-13 23:28:20 +00001078- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1079 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1080 and "%zu" for unsigned integers of type ``size_t``.
1081
Anthony Baxter51bcb682006-04-05 14:51:42 +00001082Tests
1083-----
1084
Nick Coghlanda2268f2006-04-24 04:37:15 +00001085- test_contextlib now checks contextlib.nested can cope with exceptions
1086 being raised and caught inside exit handlers.
1087
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001088- test_cmd_line now checks operation of the -m and -c command switches
1089
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001090- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1091 it separately and by hand. It also wasn't cleaning up its changes to
1092 the current Decimal context.
1093
Thomas Woutersabd08882006-04-26 15:53:30 +00001094- regrtest.py now has a -M option to run tests that test the new limits of
1095 containers, on 64-bit architectures. Running these tests is only sensible
1096 on 64-bit machines with more than two gigabytes of memory. The argument
1097 passed is the maximum amount of memory for the tests to use.

1106-------------
1107
Tim Petersb06d28c2006-05-12 01:57:59 +00001108- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1109
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001110- PEP 343: Added Context Types section to the library reference
1111 and attempted to bring other PEP 343 related documentation into
1112 line with the implementation and/or python-dev discussions.
1113
Tim Peters8dc73d22006-04-24 02:03:16 +00001114- Bug #1337990: clarified that ``doctest`` does not support examples
1115 requiring both expected output and an exception.

1119=================================
1120
Anthony Baxterebed3f62006-04-03 15:03:44 +00001121*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001122
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001123Core and builtins
1124-----------------
1125
Nick Coghlan43832302006-04-23 17:04:07 +00001126- PEP 338: -m command line switch now delegates to runpy.run_module
1127 allowing it to support modules in packages and zipfiles
1128
Martin v. Löwisc661b882006-04-20 04:54:23 +00001129- On Windows, .DLL is not an accepted file name extension for
1130 extension modules anymore; extensions are only found if they
1131 end in .PYD.
1132
Martin v. Löwisea62d252006-04-03 10:56:49 +00001133- Bug #1421664: sys.stderr.encoding is now set to the same value as
1134 sys.stdout.encoding.
1135
Neal Norwitz92e212f2006-04-03 04:48:37 +00001136- __import__ accepts keyword arguments.
1137
Georg Brandlccadf842006-03-31 18:54:53 +00001138- Patch #1460496: round() now accepts keyword arguments.
1139
Anthony Baxter262c00a2006-03-30 10:53:17 +00001140- Fixed bug #1459029 - unicode reprs were double-escaped.
1141
Hye-Shik Changd478f342006-03-23 12:32:36 +00001142- Patch #1396919: The system scope threads are reenabled on FreeBSD
1143 5.4 and later versions.
1144
Neal Norwitze98ccf62006-03-23 05:39:47 +00001145- Bug #1115379: Compiling a Unicode string with an encoding declaration
1146 now gives a SyntaxError.
1147
Georg Brandlabd1ff82006-03-18 07:59:59 +00001148- Previously, Python code had no easy way to access the contents of a
1149 cell object. Now, a ``cell_contents`` attribute has been added
1150 (closes patch #1170323).
1151
Tim Peterscf79aac2006-03-16 01:14:46 +00001152- Patch #1123430: Python's small-object allocator now returns an arena to
1153 the system ``free()`` when all memory within an arena becomes unused
1154 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1155 freed. Some applications will see a drop in virtual memory size now,
1156 especially long-running applications that, from time to time, temporarily
1157 use a large number of small objects. Note that when Python returns an
1158 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001159 platform C library will in turn return that memory to the operating system.
1160 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001161 appears to be effective at least on Microsoft C and gcc-based systems.
1162 Thanks to Evan Jones for hard work and patience.
1163
Georg Brandl533ff6f2006-03-08 18:09:27 +00001164- Patch #1434038: property() now uses the getter's docstring if there is
1165 no "doc" argument given. This makes it possible to legitimately use
1166 property() as a decorator to produce a read-only property.
1167
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001168- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1169 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1170 of requiring an int or long in slicing and a few other contexts, enabling
1171 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1172
Neal Norwitz995acdf2006-03-07 05:01:00 +00001173- Fixed various bugs reported by Coverity's Prevent tool.
1174
Brett Cannonbf364092006-03-01 04:25:17 +00001175- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1176 new exception base class, BaseException, which has a new message attribute.
1177 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1178 Raising a string exception now raises a DeprecationWarning.
1179
Thomas Woutersfb609f42006-02-28 16:37:25 +00001180- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1181 explicitly relative, using 'from .module import name' to mean 'from the same
1182 package as this module is in. Imports without dots still default to the
1183 old relative-then-absolute, unless 'from __future__ import
1184 absolute_import' is used.
1185
Brett Cannona7446e32006-02-27 23:39:10 +00001186- Properly check if 'warnings' raises an exception (usually when a filter set
1187 to "error" is triggered) when raising a warning for raising string
1188 exceptions.
1189
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001190- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001191 The name was removed from Include/code.h.
1192
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001193- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001194
Guido van Rossum1968ad32006-02-25 22:38:04 +00001195- Patch 1433928:
1196 - The copy module now "copies" function objects (as atomic objects).
1197 - dict.__getitem__ now looks for a __missing__ hook before raising
1198 KeyError.
1199
Tim Peters84ef21c2006-02-28 20:39:06 +00001200- PEP 343: with statement implemented. Needs ``from __future__ import
1201 with_statement``. Use of 'with' as a variable will generate a warning.
1202 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001203 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001204 The following objects have __context__ methods:
1205 - The built-in file type.
1206 - The thread.LockType type.
1207 - The following types defined by the threading module:
1208 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1209 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001210
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001211- Fix the encodings package codec search function to only search
1212 inside its own package. Fixes problem reported in patch #1433198.
1213
1214 Note: Codec packages should implement and register their own
1215 codec search function. PEP 100 has the details.
1216
Tim Peters9ea89d22006-06-04 03:26:02 +00001217- PEP 353: Using ``Py_ssize_t`` as the index type.
1218
1219- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1220 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1221 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1222 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1223 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001224
Neal Norwitzfc76d632006-01-10 06:03:13 +00001225- Patch #1400181, fix unicode string formatting to not use the locale.
1226 This is how string objects work. u'%f' could use , instead of .
1227 for the decimal point. Now both strings and unicode always use periods.
1228
Neal Norwitz671b9e32006-01-09 07:07:12 +00001229- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1230 configure would break checking curses.h.
1231
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001232- Bug #959576: The pwd module is now builtin. This allows Python to be
1233 built on UNIX platforms without $HOME set.
1234
Neal Norwitzc10978f2005-12-19 06:07:16 +00001235- Bug #1072182, fix some potential problems if characters are signed.
1236
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001237- Bug #889500, fix line number on SyntaxWarning for global declarations.
1238
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001239- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1240
Neal Norwitze7214a12005-12-18 05:03:17 +00001241- Support for converting hex strings to floats no longer works.
1242 This was not portable. float('0x3') now raises a ValueError.
1243
Barry Warsaw2a38a862005-12-18 01:27:35 +00001244- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001245 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001246 is now displayed in interactive prompt banner.
1247
Georg Brandlfa166682005-12-17 21:45:17 +00001248- Implementation of PEP 341 - Unification of try/except and try/finally.
1249 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001250 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001251
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001252- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1253 now encodes backslash correctly.
1254
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001255- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1256
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001257- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001258 and long longs.
1259
Neal Norwitz67715f02005-11-09 06:59:35 +00001260- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001261 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001262 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001263
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001264- Replaced most Unicode charmap codecs with new ones using the
1265 new Unicode translate string feature in the builtin charmap
1266 codec; the codecs were created from the mapping tables available
1267 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1268 encodings now include a mapping for the Apple logo)
1269
Tim Peterse3547fd2005-12-16 23:13:57 +00001270- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001271
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001272- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001273
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001274- A new AST parser implementation was completed. The abstract
1275 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001276 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001277
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001278- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001279 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1280
Neal Norwitz708e51a2005-10-03 04:48:15 +00001281- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1282
Neal Norwitz11bd1192005-10-03 00:54:56 +00001283- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1284 Provide a warning when a directory is passed on the command line.
1285
Neal Norwitz40d37812005-10-02 01:48:49 +00001286- Fix segfault with invalid coding.
1287
1288- SF bug #772896: unknown encoding results in MemoryError.
1289
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001290- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001291 supported a __len__() method which evaluated to False when the iterator
1292 was empty.
1293
Guido van Rossum630db602005-09-20 18:49:54 +00001294- On 64-bit platforms, when __len__() returns a value that cannot be
1295 represented as a C int, raise OverflowError.
1296
Skip Montanarof8948ca2005-09-19 03:54:46 +00001297- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001298 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001299
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001300- SF bug #893549: parsing keyword arguments was broken with a few format
1301 codes.
1302
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001303- Changes donated by Elemental Security to make it work on AIX 5.3
1304 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1305 bug #105470: test_pwd fails on 64bit system (Opteron).
1306
Guido van Rossum539c6622005-09-14 17:49:54 +00001307- Changes donated by Elemental Security to make it work on HP-UX 11 on
1308 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1309
Georg Brandl4550b8d2005-08-26 06:43:52 +00001310- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001311 (fixes bug #1119418).
1312
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001313- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1314
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001315- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1316 exceptions that cause a function to exit.
1317
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001318- The implementation of set() and frozenset() was revised to use its
1319 own internal data structure. Memory consumption is reduced by 1/3
1320 and there are modest speed-ups as well. The API is unchanged.
1321
Tim Petersde7990b2005-07-17 23:45:23 +00001322- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1323
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001324- SF bug #1229429: PyObject_CallMethod failed to decrement some
1325 reference counts in some error exit cases.
1326
Tim Petersecc6e6a2005-07-10 22:30:55 +00001327- SF bug #1185883: Python's small-object memory allocator took over
1328 a block managed by the platform C library whenever a realloc specified
1329 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001330 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001331 portable way to copy data from the C-managed block into Python's
1332 small-object space without risking a memory fault. Python's small-object
1333 realloc now leaves such blocks under the control of the platform C
1334 realloc.
1335
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001336- SF bug #1232517: An overflow error was not detected properly when
1337 attempting to convert a large float to an int in os.utime().
1338
Raymond Hettinger3296e692005-06-29 23:29:56 +00001339- SF bug #1224347: hex longs now print with lowercase letters just
1340 like their int counterparts.
1341
Michael W. Hudson188d4362005-06-20 16:52:57 +00001342- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1343 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1344 interpreter states; back out that fix and do a better job (see
1345 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1346 for a longer write-up of the problem).
1347
Michael W. Hudsondf888462005-06-03 14:41:55 +00001348- SF patch #1180995: marshal now uses a binary format by default when
1349 serializing floats.
1350
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001351- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1352 the routines that promise to produce IEEE 754 binary representations
1353 of floats now simply copy bytes around.
1354
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001355- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1356 278.
1357
Brett Cannonc3647ac2005-04-26 03:45:26 +00001358- patch #1109424: int, long, float, complex, and unicode now check for the
1359 proper magic slot for type conversions when subclassed. Previously the
1360 magic slot was ignored during conversion. Semantics now match the way
1361 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001362 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001363 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001364 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001365
Barry Warsawc8d907c2005-04-19 23:43:40 +00001366- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1367 NULL, now raise an AttributeError when attempting to set or delete the
1368 attribute. Previously a TypeError was raised, but this was inconsistent
1369 with the equivalent pure-Python implementation.
1370
Michael W. Hudson774479c2005-04-18 08:46:17 +00001371- It is now safe to call PyGILState_Release() before
1372 PyEval_InitThreads() (note that if there is reason to believe there
1373 are multiple threads around you still must call PyEval_InitThreads()
1374 before using the Python API; this fix is for extension modules that
1375 have no way of knowing if Python is multi-threaded yet).
1376
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001377- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1378 disabled caused a crash.
1379
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001380- Bug #1165306: instancemethod_new allowed the creation of a method
1381 with im_class == im_self == NULL, which caused a crash when called.
1382
Tim Petersecc6e6a2005-07-10 22:30:55 +00001383- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001384 fixes the crash seen in bug #1165761
1385
Raymond Hettinger96229b12005-03-11 06:49:40 +00001386- Added two new builtins, any() and all().
1387
Brett Cannon409d8f22005-03-05 06:47:57 +00001388- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001389 (e.g., ``class C(): pass`` is no longer a syntax error).
1390 Patch #1176012 added support to the 'parser' module and 'compiler' package
1391 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001392
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001393- Patch #1115086: Support PY_LONGLONG in structmember.
1394
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001395- Bug #1155938: new style classes did not check that __init__() was
1396 returning None.
1397
Tim Petersecc6e6a2005-07-10 22:30:55 +00001398- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001399 ('\') with a specific error message.
1400
Martin v. Löwisff232d72005-03-03 09:24:38 +00001401- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1402
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001403- Bug #1124295: the __name__ attribute of file objects was
1404 inadvertently made inaccessible in restricted mode.
1405
Tim Petersecc6e6a2005-07-10 22:30:55 +00001406- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001407 an ferror() call.
1408
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001409- min() and max() now support key= arguments with the same meaning as in
1410 list.sort().
1411
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001412- The peephole optimizer now performs simple constant folding in expressions:
1413 (2+3) --> (5).
1414
Raymond Hettingera422c342005-01-11 03:03:27 +00001415- set and frozenset objects can now be marshalled. SF #1098985.
1416
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001417- Bug #1077106: Poor argument checking could cause memory corruption
1418 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001419
Jeremy Hyltonab630502005-02-04 18:44:06 +00001420- The parser did not complain about future statements in illegal
1421 positions. It once again reports a syntax error if a future
1422 statement occurs after anything other than a doc string.
1423
Neil Schemenauercf52c072005-08-12 17:34:58 +00001424- Change the %s format specifier for str objects so that it returns a
1425 unicode instance if the argument is not an instance of basestring and
1426 calling __str__ on the argument returns a unicode instance.
1427
Tim Petersf4e69282006-02-27 17:15:31 +00001428- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1429 current thread state when the auto-GIL-state machinery knows about
1430 it (since the thread state is being deleted, continuing to remember it
1431 can't help, but can hurt if another thread happens to get created with
1432 the same thread id).
1433
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001434Extension Modules
1435-----------------
1436
Georg Brandl43f08a82006-03-31 18:01:16 +00001437- Patch #1380952: fix SSL objects timing out on consecutive read()s

Neal Norwitz05a45592006-03-20 06:30:08 +00001439- Patch #1309579: wait3 and wait4 were added to the posix module.
1440
Anthony Baxterfa869072006-03-20 05:21:58 +00001441- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1442 In addition, the existing ulaw code was updated.
1443
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001444- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001445 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001446
Neal Norwitz10be10c2006-03-16 06:50:13 +00001447- Everything under lib-old was removed. This includes the following modules:
1448 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001449 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001450 util, whatsound, whrandom, zmod
1451
1452- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1453
1454- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001455 is deprecated. The undocumented re.engine variable no longer exists.
1456
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001457- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1458 SS2 (single-shift 2) escape sequences correctly.
1459
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001460- The unicodedata module was updated to the 4.1 version of the Unicode
1461 database. The 3.2 version is still available as unicodedata.db_3_2_0
1462 for applications that require this specific version (such as IDNA).
1463
Neal Norwitzb62c4332006-03-04 18:35:47 +00001464- The timing module is no longer built by default. It was deprecated
1465 in PEP 4 in Python 2.0 or earlier.
1466
Guido van Rossum1968ad32006-02-25 22:38:04 +00001467- Patch 1433928: Added a new type, defaultdict, to the collections module.
1468 This uses the new __missing__ hook behavior added to dict (see above).
1469
Georg Brandldbd83392006-02-20 09:42:33 +00001470- Bug #854823: socketmodule now builds on Sun platforms even when
1471 INET_ADDRSTRLEN is not defined.
1472
Georg Brandlf4f44152006-02-18 22:29:33 +00001473- Patch #1393157: os.startfile() now has an optional argument to specify
1474 a "command verb" to invoke on the file.
1475
Neal Norwitz082b2df2006-02-07 07:04:46 +00001476- Bug #876637, prevent stack corruption when socket descriptor
1477 is larger than FD_SETSIZE.
1478
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001479- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1480 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1481 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1482
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001483- Patch #1422385: The nis module now supports access to domains other
1484 than the system default domain.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001624- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1625 been renamed to have only a single underscore prefix. This was done to
1626 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001627
Nick Coghlan43832302006-04-23 17:04:07 +00001628- PEP 338: new module runpy defines a run_module function to support
1629 executing modules which provide access to source code or a code object
1630 via the PEP 302 import mechanisms.
1631
Anthony Baxter93f5b932006-04-03 08:05:07 +00001632- The email module's parsedate_tz function now sets the daylight savings

1640 in attribute values.
1641
Anthony Baxterc51ee692006-04-01 00:57:31 +00001642- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001643 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001644 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001645 module will not be built.
1646
Tim Petersc17976e2006-04-01 00:26:53 +00001647- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1648 aren't officially supported here, and trying to use them will probably
1649 raise an exception some day. But dicts have been allowed, and "mostly
1650 worked", so support for them won't go away without warning.
1651
Georg Brandl338ef7d2006-03-31 18:42:16 +00001652- Bug #1445068: getpass.getpass() can now be given an explicit stream

1670
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001671- email 4.0 package now integrated. This is largely the same as the email 3.0
1672 package that was included in Python 2.3, except that PEP 8 module names are
1673 now used (e.g. mail.message instead of email.Message). The MIME classes
1674 have been moved to a subpackage (e.g. email.mime.text instead of
1675 email.MIMEText). The old names are still supported for now. Several
1676 deprecated Message methods have been removed and lots of bugs have been
1677 fixed. More details can be found in the email package documentation.
1678
Walter Dörwald40108c92006-03-27 08:15:44 +00001679- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1680 (a subclass of tuple) that provides incremental decoders and encoders
1681 (a way to use stateful codecs without the stream API). Python functions
1682 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1683 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1684 have been added.

1687 a ValueError instead of a StopIteration now (like file and cString.String do).
1688 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1689 called before (like file and StringIO.StringIO do).

Georg Brandl4edd9892006-01-13 16:59:46 +00001751- Bug #1403410: The warnings module now doesn't get confused
1752 when it can't find out the module name it generates a warning for.
Georg Brandlb709c2c2006-01-20 09:07:35 +00001753

1757
Neal Norwitz338e7862005-12-23 21:27:46 +00001758- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
1759 LoadError as documented, instead of IOError. For compatibility,
1760 LoadError subclasses IOError.
1761
Brett Cannon3cbd0382005-12-16 22:49:23 +00001762- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001763 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1764 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1765 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1766 Ronald L. Rivest offered this advice for Python:
1767
1768 "The consensus of researchers in this area (at least as
1769 expressed at the NIST Hash Function Workshop 10/31/05),
1770 is that SHA-256 is a good choice for the time being, but
1771 that research should continue, and other alternatives may
1772 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001773
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001774- Added a subset of Fredrik Lundh's ElementTree package. Available

1827 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001828 correct line numbers for decoding errors in source code.

1851 to W3C name (404 -> 'Not Found'). RFE #1216944.
1852
Georg Brandl9e43acf2005-07-04 17:16:07 +00001853- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1854 as this can cause problems with apps closing all file descriptors.

1867 Bug #1224621.
1868
Raymond Hettinger68c04532005-06-10 11:05:19 +00001869- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001870 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001871 the generate_tokens() function now accepts a callable argument that
1872 terminates by raising StopIteration.
1873
Georg Brandl9166e1a2005-06-04 09:20:03 +00001874- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1878
Skip Montanaro174dd222005-05-14 20:54:16 +00001879- Patch #1120353: The xmlrpclib module provides better, more transparent,

1882 class at all.
1883
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001884- distutils.commands.upload was added to support uploading distribution

1888 them to PyPI.
1889
Raymond Hettinger267b8682005-03-27 10:47:39 +00001890- decimal operator and comparison methods now return NotImplemented
1891 instead of raising a TypeError when interacting with other types. This
1892 allows other classes to implement __radd__ style methods and have them
1893 work as expected.
1894
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001895- Bug #1163325: Decimal infinities failed to hash. Attempting to
1896 hash a NaN raised an InvalidOperation instead of a TypeError.
1897
Tim Petersecc6e6a2005-07-10 22:30:55 +00001898- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1932
Guido van Rossumd0641422005-02-03 15:01:24 +00001933- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1934 disables recursive traversal through instance attributes, which can
1935 be exploited in various ways.
1936
Tim Peterse3547fd2005-12-16 23:13:57 +00001937- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001938 flags on the HTTP listening socket.
1939

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001948- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1949
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001950- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1951
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001952- Enhancements to the csv module:
1953
1954 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001955 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001956 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001957 + Dialect parameter parsing has been re-implemented to improve error
1958 reporting.
1959 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1960 dictates.
1961 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001962 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001963 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001964 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1965 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001966 + reader now allows \r characters to be quoted (previously it only allowed
1967 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001968 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001969 + Dialect classes passed to the module are no longer instantiated by
1970 the module before being parsed (the former validation scheme required
1971 this, but the mechanism was unreliable).
1972 + The dialect registry now contains instances of the internal
1973 C-coded dialect type, rather than references to python objects.
1974 + the internal c-coded dialect type is now immutable.
1975 + register_dialect now accepts the same keyword dialect specifications
1976 as the reader and writer, allowing the user to register dialects
1977 without first creating a dialect class.
1978 + a configurable limit to the size of parsed fields has been added -
1979 previously, an unmatched quote character could result in the entire
1980 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001981 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001982 the parser field size limit (returning the former limit). The initial
1983 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001984 + A line_num attribute has been added to the reader object, which tracks
1985 the number of lines read from the source iterator. This is not
1986 the same as the number of records returned, as records can span
1987 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001988 + reader and writer objects were not being registered with the cyclic-GC.
1989 This has been fixed.
1990
Brett Cannone6539c42005-01-08 02:43:53 +00001991- _DummyThread objects in the threading module now delete self.__block that is
1992 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1993 lock primitives tend to be limited in number and thus should not be wasted on
1994 a _DummyThread object. Fixes bug #1089632.
1995
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001996- The imghdr module now detects Exif files.
1997
Raymond Hettinger6065d322004-12-20 23:51:53 +00001998- StringIO.truncate() now correctly adjusts the size attribute.
1999 (Bug #951915).
2000
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002001- locale.py now uses an updated locale alias table (built using
2002 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2003 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002004 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002005
Raymond Hettinger3557f422004-12-07 12:02:02 +00002006- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2007
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002008- the pickle module no longer accepts the deprecated None option in the
2009 args tuple returned by __reduce__().
2010
Brett Cannon84667c02004-12-07 03:25:18 +00002011- optparse now optionally imports gettext. This allows its use in setup.py.
2012

2020
Raymond Hettinger664347b2004-12-04 21:21:53 +00002021- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2022 extended or overridden by subclasses. Formerly, the subclassed method would
2023 be ignored by the rest of the module. (Bug #1078905).
2024
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002025- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002026 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002027
Walter Dörwald36733692004-12-22 12:50:50 +00002028- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2029 once when a size argument is given. This prevents a buffer overflow in the
2030 tokenizer with very long source lines.
2031
Barry Warsaw538561e2006-01-01 21:48:54 +00002032- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2033 immediately after creating the object, without any intervening
2034 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002035
Skip Montanaro05885812005-01-16 20:48:27 +00002036- The reconvert.quote function can now emit triple-quoted strings. The
2037 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002038
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002039- ``UserString.MutableString`` now supports negative indices in
2040 ``__setitem__`` and ``__delitem__``
2041
Greg Ward40407942005-03-05 02:53:17 +00002042- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2043 correctly.
2044
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002045- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2046 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2047 character even if the user has passed a size parameter to get a proper
2048 line ending. Remove the special handling of a "\r\n" that has been split
2049 between two lines.
2050
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002051- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2052 about illegal code points. The codec now supports PEP 293 style error
2053 handlers.
2054
Walter Dörwald78a78b02005-09-01 12:04:29 +00002055- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002056 from the input stream, so that the output is a byte string in the correct
2057 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002058
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002059- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2060 considering it exactly like a '*'.
2061
Walter Dörwald007f8df2005-10-09 19:42:27 +00002062- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2063 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002064
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002065- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2066
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002067- Patch #1413711: Certain patterns of differences were making difflib
2068 touch the recursion limit.
2069
Walter Dörwald58917a62006-03-31 15:26:22 +00002070- Bug #947906: An object oriented interface has been added to the calendar
2071 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002072 called as a script (e.g. via ``python -mcalendar``). Localized month and
2073 weekday names can be ouput (even if an exotic encoding is used) using
2074 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002076Build
2077-----
2078
Neal Norwitz602d3392006-03-31 08:21:40 +00002079- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2080 by using -mieee gcc option.
2081

2083
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002084- Build support for Win64-AMD64 was added.
2085
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002086- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2087
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002088- Patch #881820: look for openpty and forkpty also in libbsd.
2089
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002090- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2091 The zlib module is now builtin on Windows.
2092
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002093- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2094
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002095- Bug #1189330: configure did not correctly determine the necessary
2096 value of LINKCC if python was built with GCC 4.0.
2097
Trent Mick8321b422005-07-26 02:29:21 +00002098- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2099 vulnerability in zlib 1.2.1 and 1.2.2.
2100
Brett Cannon08cd5982005-04-24 22:26:38 +00002101- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2102 flags that change binary compatibility. Changes were also made to
2103 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002104 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002105
Bob Ippolitoed233462005-03-29 13:47:59 +00002106- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2107 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2108 no longer exists). This configure patch makes things right.
2109
Martin v. Löwise2713be2005-03-08 15:03:08 +00002110- Bug #1158607: Build with --disable-unicode again.
2111
Brett Cannon46d96232005-02-16 00:07:19 +00002112- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2113 defined. Discovered as a result of not being able to build on OS X.
2114
Brett Cannon516592f2004-12-07 00:42:59 +00002115- setup.py now uses the directories specified in LDFLAGS using the -L option
2116 and in CPPFLAGS using the -I option for adding library and include
2117 directories, respectively, for compiling extension modules against. This has
2118 led to the core being compiled using the values in CPPFLAGS. It also removes
2119 the need for the special-casing of both DarwinPorts and Fink for darwin since
2120 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2121 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2122 Fink, ``-I/opt/local/include`` for DarwinPorts).
2123
Brett Cannon43802422005-02-10 20:48:03 +00002124- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2125 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2126 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2127 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002129C API
2130-----
2131
Tim Petersc9d78aa2006-03-26 23:27:58 +00002132- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2133 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2134 is obtained via the ``PyObject_`` family, it must be released via the
2135 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2136 always been officially true, but when Python's small-object allocator was
2137 introduced, an attempt was made to cater to a few extension modules
2138 discovered at the time that obtained memory via ``PyObject_New`` but
2139 released it via ``PyMem_DEL``. It's years later, and if such code still
2140 exists it will fail now (probably with segfaults, but calling wrong
2141 low-level memory management functions can yield many symptoms).
2142
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002143- Added a C API for set and frozenset objects.
2144
Raymond Hettinger66517482004-12-03 11:45:13 +00002145- Removed PyRange_New().
2146
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002147- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2148 mapping argument now. This string is used as a mapping table. Byte values
2149 greater than the length of the string and 0xFFFE are treated as undefined
2150 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002156- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002157
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002158- Patch #1276356: New resource "urlfetch" is implemented. This enables
2159 even impatient people to run tests that require remote files.
