14
Brett Cannonf6aa86e2006-09-20 18:43:13 +000015- Allow exception instances to be directly sliced again.
16
Brett Cannon9adeab72006-09-20 18:34:28 +000017- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
18 allows calling unicode() on exceptions classes directly to succeed.
19
Georg Brandlec6c2df2006-09-11 09:38:35 +000020- Make _PyGILState_NoteThreadState() static, it was not used anywhere
21 outside of pystate.c and should not be necessary.
22
Georg Brandl4e933132006-09-06 20:05:58 +000023- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
24 Also make sure that every exception class has __module__ set to
25 'exceptions'.
26
Georg Brandl98775df2006-09-06 06:09:31 +000027- Bug #1550983: emit better error messages for erroneous relative
28 imports (if not in package and if beyond toplevel package).
29
Tim Petersc10c9d02006-09-05 02:18:09 +000030- Overflow checking code in integer division ran afoul of new gcc
31 optimizations. Changed to be more standard-conforming.
32

38 head is the original string if sep was not found.
39
Neal Norwitzdac090d2006-09-05 03:53:08 +000040- Bug #1520864: unpacking singleton tuples in list comprehensions and
41 generator expressions (x for x, in ... ) works again. Fixing this problem
42 required changing the .pyc magic number. This means that .pyc files
43 generated before 2.5c2 will be regenerated.
44
Neal Norwitzca460d92006-09-06 06:28:06 +000045- with and as are now keywords.

Guido van Rossumc69ac252006-08-10 18:09:25 +0000133What's New in Python 2.5 release candidate 1?
134=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000135
Anthony Baxterb4096662006-08-16 03:42:26 +0000136*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000137
138Core and builtins
139-----------------
140
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000141- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000142 compared equal or unequal to a string and a UnicodeDecodeError
143 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000144
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000145 Instead, the equal (==) and unequal (!=) comparison operators will
146 now issue a UnicodeWarning and interpret the two objects as
147 unequal. The UnicodeWarning can be filtered as desired using
148 the warning framework, e.g. silenced completely, turned into an
149 exception, logged, etc.
150
151 Note that compare operators other than equal and unequal will still
152 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000153
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000154- Fix segfault when doing string formatting on subclasses of long.
155
156- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
157 with new-style classes.
158
159- Fix bug related to __len__ functions returning negative values with
160 classic classes.
161
162- Patch #1538606, Fix __index__() clipping. There were some problems
163 discovered with the API and how integers that didn't fit into Py_ssize_t
164 were handled. This patch attempts to provide enough alternatives
165 to effectively use __index__.
166
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000167- Bug #1536021: __hash__ may now return long int; the final hash
168 value is obtained by invoking hash on the long int.
169
Thomas Hellerab1049c2006-08-08 17:37:00 +0000170- Bug #1536786: buffer comparison could emit a RuntimeWarning.
171
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000172- Bug #1535165: fixed a segfault in input() and raw_input() when
173 sys.stdin is closed.
174
Thomas Heller74d36f02006-08-04 18:17:40 +0000175- On Windows, the PyErr_Warn function is now exported from
176 the Python dll again.
177
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000178- Bug #1191458: tracing over for loops now produces a line event
179 on each iteration. Fixing this problem required changing the .pyc
180 magic number. This means that .pyc files generated before 2.5c1
181 will be regenerated.
182
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000183- Bug #1333982: string/number constants were inappropriately stored
184 in the byte code and co_consts even if they were not used, ie
185 immediately popped off the stack.
186
Georg Brandle9462c72006-08-04 18:03:37 +0000187- Fixed a reference-counting problem in property().
188
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000189
190Library
191-------
192
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000193- Fix a bug in the ``compiler`` package that caused invalid code to be
194 generated for generator expressions.
195
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000196- The distutils version has been changed to 2.5.0. The change to
197 keep it programmatically in sync with the Python version running
198 the code (introduced in 2.5b3) has been reverted. It will continue
199 to be maintained manually as static string literal.
200
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000201- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000202 and this cannot be converted to the required C type, an exception is
203 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000204 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000205
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000206- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000207 an exception.
208
Tim Petersc10c9d02006-09-05 02:18:09 +0000209- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000210 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000211 workarounds for clocks with low resolution, to stop the code yielding
212 duplicate UUIDs.
213
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000214- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
215 before raising SystemExit, allowing IDLE to honor quit() and exit().
216
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000217- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
218
Georg Brandl7a1af772006-08-14 21:55:28 +0000219- Patch #1536071: trace.py should now find the full module name of a
220 file correctly even on Windows.
221
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000222- logging's atexit hook now runs even if the rest of the module has
223 already been cleaned up.
224
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000225- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000226
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000227- Bug #1531405, format_exception no longer raises an exception if
228 str(exception) raised an exception.
229
Neil Schemenauer06ded092006-08-04 16:20:30 +0000230- Fix a bug in the ``compiler`` package that caused invalid code to be
231 generated for nested functions.
232

244
Thomas Heller86720042006-08-14 11:17:48 +0000245- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
246 uses the _as_parameter_ attribute when objects are passed to foreign
247 function calls. The ctypes version number was changed to 1.0.1.
248
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000249- Bug #1530559, struct.pack raises TypeError where it used to convert.

Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000304- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000305 returned a long (see PEP 353).
306
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000307- Bug #1515471: string.replace() accepts character buffers again.
308
Neal Norwitz07aadb12006-07-30 06:55:48 +0000309- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
310 This provides the proper warning for struct.pack().
311 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
312
Neal Norwitz0d62a062006-07-30 06:53:31 +0000313- Patch #1531113: Fix augmented assignment with yield expressions.
314 Also fix a SystemError when trying to assign to yield expressions.

Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000316- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
317 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
318 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
319 excessive filesystem operations during imports.
320
Tim Petersbc24eee2006-07-27 01:14:53 +0000321- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
322 operations on signed longs that are formally undefined by C.
323 Unfortunately, at least one compiler now cares about that, so complicated
324 the code to make that compiler happy again.
325
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000326- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
327
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000328- Patch #1232023: Stop including current directory in search
329 path on Windows.
330
Neal Norwitze1fdb322006-07-21 05:32:28 +0000331- Fix some potential crashes found with failmalloc.
332
Neal Norwitze7563102006-07-17 01:00:16 +0000333- Fix warnings reported by Klocwork's static analysis tool.
334
Neal Norwitz84be93b2006-07-16 01:50:38 +0000335- Bug #1512814, Fix incorrect lineno's when code within a function
336 had more than 255 blank lines.
337
Georg Brandl9dceedb2006-07-12 15:31:17 +0000338- Patch #1521179: Python now accepts the standard options ``--help`` and
339 ``--version`` as well as ``/?`` on Windows.
340
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000341- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000342 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000343 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000344
Tim Peters112aad32006-07-19 00:03:19 +0000345- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000346 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000347 new ``sys._current_frames()`` returns a dictionary with one entry,
348 mapping the faux "thread id" 0 to the current frame.
349
Ronald Oussoren3075e162006-07-25 20:28:55 +0000350- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

354-------
355
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000356- Correction of patch #1455898: In the mbcs decoder, set final=False
357 for stream decoder, but final=True for the decode function.
358
Georg Brandl07fec3a2006-08-01 18:49:24 +0000359- os.urandom no longer masks unrelated exceptions like SystemExit or
360 KeyboardInterrupt.
361
Tim Peters4643c2f2006-08-10 22:45:34 +0000362- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000363 shutil.copytree on Windows
364
Georg Brandle34ac7c2006-07-30 11:07:23 +0000365- Bug #1002398: The documentation for os.path.sameopenfile now correctly
366 refers to file descriptors, not file objects.
367
Tim Petersc10c9d02006-09-05 02:18:09 +0000368- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000369 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000370 #1513611, and probably others.
371
Georg Brandledd9b0d2006-07-29 09:33:26 +0000372- Bug #1441397: The compiler module now recognizes module and function
373 docstrings correctly as it did in Python 2.4.
374
Tim Peters6f681472006-07-27 23:44:37 +0000375- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
376 lost that tests are sorted by name before being run. This rarely
377 matters for well-written tests, but can create baffling symptoms if
378 side effects from one test to the next affect outcomes. ``DocTestFinder``
379 has been changed to sort the list of tests it returns.
380
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000381- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000382 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000383
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000384- Bug #978833: Really close underlying socket in _socketobject.close.
385
Georg Brandl8c036cc2006-08-20 13:15:39 +0000386- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
387 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000388
Georg Brandlcf0c1722006-07-26 07:23:32 +0000389- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
390 to recursive calls and call it with the failing package name.
391
Martin v. Löwis0b483032006-07-25 09:53:12 +0000392- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
393
Georg Brandlc13c34c2006-07-24 14:09:56 +0000394- Patch #1515343: Fix printing of deprecated string exceptions with a
395 value in the traceback module.
396
Greg Ward48fae7a2006-07-23 16:05:51 +0000397- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
398
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000399- Patch #1524429: Use repr() instead of backticks in Tkinter again.
400
Brett Cannoncaebe222006-07-18 04:41:36 +0000401- Bug #1520914: Change time.strftime() to accept a zero for any position in its
402 argument tuple. For arguments where zero is illegal, the value is forced to
403 the minimum value that is correct. This is to support an undocumented but
404 common way people used to fill in inconsequential information in the time
405 tuple pre-2.4.
406
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000407- Patch #1220874: Update the binhex module for Mach-O.
408
Barry Warsawb110bad2006-07-21 14:51:07 +0000409- The email package has improved RFC 2231 support, specifically for
410 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
411 (name*0=<blah>) parameter continuations. This may change the types of
412 values returned from email.message.Message.get_param() and friends.
413 Specifically in some cases where non-encoded continuations were used,
414 get_param() used to return a 3-tuple of (None, None, string) whereas now it
415 will just return the string (since non-encoded continuations don't have
416 charset and language parts).
417
418 Also, whereas % values were decoded in all parameter continuations, they are
419 now only decoded in encoded parameter parts.
420
Ronald Oussoren3075e162006-07-25 20:28:55 +0000421- Bug #1517990: IDLE keybindings on MacOS X now work correctly
422
423- Bug #1517996: IDLE now longer shows the default Tk menu when a
424 path browser, class browser or debugger is the frontmost window on MacOS X
425
Barry Warsaw00decd72006-07-27 23:43:15 +0000426- Patch #1520294: Support for getset and member descriptors in types.py,
427 inspect.py, and pydoc.py. Specifically, this allows for querying the type
428 of an object against these built-in types and more importantly, for getting
429 their docstrings printed in the interactive interpreter's help() function.

433-----------------
434
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000435- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
436 a socket operation on a socket with a timeout, the exception will be
437 caught correctly. Previously, the exception was not caught.
438
Thomas Heller1393d6a2006-07-28 21:43:20 +0000439- Patch #1529514: The _ctypes extension is now compiled on more
440 openbsd target platforms.
441
Tim Peters9cab5932006-07-28 00:30:00 +0000442- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
443 a memory leak, affecting pickles and deep copies.
444
Tim Petersbc24eee2006-07-27 01:14:53 +0000445- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000446 Paul Eggert.
447
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000448- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
449
Thomas Hellerce049a02006-07-14 17:51:14 +0000450- Patch #1521817: Index range checking on ctypes arrays containing
451 exactly one element enabled again. This allows iterating over these
452 arrays, without the need to check the array size before.
453
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000454- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000455 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000456 /dev/null in certain cases; this is now fixed.
457
Thomas Heller47d7a062006-07-12 08:43:47 +0000458- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
459 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000460
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000461- Because of a misspelled preprocessor symbol, ctypes was always
462 compiled without thread support; this is now fixed.
463
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000464- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
465 methods now allow their database parameter to be None as the
466 sleepycat API allows.
467
Matt Flemingec926502006-07-28 11:27:27 +0000468- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
469 bluetooth API compared with Linux and FreeBSD.
470
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000471Tests
472-----
473
474- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
475 how long the test file should take to play. Now accepts taking 2.93 secs
476 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
477
Georg Brandl4793aa32006-07-28 18:31:39 +0000478- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
479 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
480 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000487Mac
488---
489
490- PythonLauncher now works correctly when the path to the script contains
491 characters that are treated specially by the shell (such as quotes).
492
493- Bug #1527397: PythonLauncher now launches scripts with the working directory
494 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000495 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000496 expect.

504Core and builtins
505-----------------
506
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000507- Bug #1441486: The literal representation of -(sys.maxint - 1)
508 again evaluates to a int object, not a long.
509
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000510- Bug #1501934: The scope of global variables that are locally assigned
511 using augmented assignment is now correctly determined.
512
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000513- Bug #927248: Recursive method-wrapper objects can now safely
514 be released.
515
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000516- Bug #1417699: Reject locale-specific decimal point in float()
517 and atof().
518
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000519- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
520 omit a default "error" argument for NULL pointer. This allows
521 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000522
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000523- Bug #1519018: 'as' is now validated properly in import statements.
524
Neal Norwitz28746ab2006-07-09 22:14:42 +0000525- On 64 bit systems, int literals that use less than 64 bits are
526 now ints rather than longs.
527
Neal Norwitzed657552006-07-10 00:04:44 +0000528- Bug #1512814, Fix incorrect lineno's when code at module scope
529 started after line 256.
530
Tim Peters32a83612006-07-10 21:08:24 +0000531- New function ``sys._current_frames()`` returns a dict mapping thread
532 id to topmost thread stack frame. This is for expert use, and is
533 especially useful for debugging application deadlocks. The functionality
534 was previously available in Fazal Majid's ``threadframe`` extension
535 module, but it wasn't possible to do this in a wholly threadsafe way from
536 an extension.

545
Tim Peters32a83612006-07-10 21:08:24 +0000546- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000547 environment variable to be set in order to the SDK environment
548 for finding the compiler, include files, etc.

553
Thomas Woutersadd19112006-07-05 11:03:49 +0000554- string.Template() now correctly handles tuple-values. Previously,
555 multi-value tuples would raise an exception and single-value tuples would
556 be treated as the value they contain, instead.
557
Martin v. Löwisede77f52006-07-03 13:01:35 +0000558- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
559 even if some data are received.
560
Martin v. Löwis45482392006-07-03 12:28:58 +0000561- Bug #1267547: Put proper recursive setup.py call into the

565 degrees and radians.
566
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000567- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000568 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000569
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000570- Bug #1514703: Only setup canvas window in turtle when the canvas
571 is created.
572
Martin v. Löwis7596e832006-07-01 15:33:37 +0000573- Bug #1513223: .close() of a _socketobj now releases the underlying
574 socket again, which then gets closed as it becomes unreferenced.
575
Fred Drake10497c82006-06-29 02:57:48 +0000576- Bug #1504333: Make sgmllib support angle brackets in quoted
577 attribute values.
578
579- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
580 sgmllib ('[' and ']' were not accepted).
581
Georg Brandl1be63af2006-06-28 20:23:25 +0000582- Fix a bug in the turtle module's end_fill function.
583
Brett Cannon53ab5b72006-06-22 16:49:14 +0000584- Bug #1510580: The 'warnings' module improperly required that a Warning
585 category be either a types.ClassType and a subclass of Warning. The proper
586 check is just that it is a subclass with Warning as the documentation states.
587
Georg Brandlad29e632006-06-21 17:45:17 +0000588- The compiler module now correctly compiles the new try-except-finally
589 statement (bug #1509132).
590
Neal Norwitz60373cd2006-06-22 06:30:50 +0000591- The wsgiref package is now installed properly on Unix.
592
Vinay Sajip28e57612006-07-01 10:45:20 +0000593- A bug was fixed in logging.config.fileConfig() which caused a crash on
594 shutdown when fileConfig() was called multiple times.
595
Gerhard Häring762fbd32006-07-02 17:48:30 +0000596- The sqlite3 module did cut off data from the SQLite database at the first
597 null character before sending it to a custom converter. This has been fixed
598 now.

Tim Peters112aad32006-07-19 00:03:19 +0000603- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
604 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
605 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000606
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000607- Assigning None to pointer type fields in ctypes structures possible
608 overwrote the wrong fields, this is fixed now.
609
610- Fixed a segfault in _ctypes when ctypes.wintypes were imported
611 on non-Windows platforms.
612
613- Bug #1518190: The ctypes.c_void_p constructor now accepts any
614 integer or long, without range checking.
615
616- Patch #1517790: It is now possible to use custom objects in the ctypes
617 foreign function argtypes sequence as long as they provide a from_param
618 method, no longer is it required that the object is a ctypes type.
619
620- The '_ctypes' extension module now works when Python is configured
621 with the --without-threads option.
622
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000623- Bug #1513646: os.access on Windows now correctly determines write
624 access, again.
625
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000626- Bug #1512695: cPickle.loads could crash if it was interrupted with
627 a KeyboardInterrupt.
628
Neal Norwitza12aa882006-07-06 06:45:08 +0000629- Bug #1296433: parsing XML with a non-default encoding and
630 a CharacterDataHandler could crash the interpreter in pyexpat.
631
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000632- Patch #1516912: improve Modules support for OpenVMS.

635-----
636
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000637- Automate Windows build process for the Win64 SSL module.
638
Tim Peters32a83612006-07-10 21:08:24 +0000639- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000640 Previously, the slight difference could cause compilation errors of the
641 'zlib' module on systems with more than one version of zlib.
642
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000643- The MSI compileall step was fixed to also support a TARGETDIR
644 with spaces in it.
645
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000646- Bug #1517388: sqlite3.dll is now installed on Windows independent
647 of Tcl/Tk.
648
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000649- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000650 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +0000652Tests
653-----
654
655- Call os.waitpid() at the end of tests that spawn child processes in order
656 to minimize resources (zombies).
657
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000658Documentation
659-------------
660
Nick Coghlan2d792252006-07-06 13:47:18 +0000661- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
662 documentation for the warnings module.
663
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000664- Patch #1509163: MS Toolkit Compiler no longer available.
665
Neal Norwitz56640df2006-07-10 02:36:41 +0000666- Patch #1504046: Add documentation for xml.etree.

Nick Coghlanc649ec52006-05-29 12:43:05 +0000669What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +0000670================================
Anthony Baxter51bcb682006-04-05 14:51:42 +0000671
Anthony Baxterd1136802006-06-19 12:04:15 +0000672*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000673
674Core and builtins
675-----------------
676
Georg Brandla56b9152006-06-19 06:35:54 +0000677- Patch #1507676: Error messages returned by invalid abstract object operations
678 (such as iterating over an integer) have been improved and now include the
679 type of the offending object to help with debugging.
680
Brett Cannonea3912b2006-06-13 21:46:41 +0000681- Bug #992017: A classic class that defined a __coerce__() method that returned
682 its arguments swapped would infinitely recurse and segfault the interpreter.
683
Neal Norwitz909eb122006-06-12 02:13:21 +0000684- Fix the socket tests so they can be run concurrently.
685
Neal Norwitzb9845e72006-06-12 02:11:18 +0000686- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000687 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000688
Brett Cannon22565aa2006-06-09 22:31:23 +0000689- Bug #532646: object.__call__() will continue looking for the __call__
690 attribute on objects until one without one is found. This leads to recursion
691 when you take a class and set its __call__ attribute to an instance of the
692 class. Originally fixed for classic classes, but this fix is for new-style.
693 Removes the infinite_rec_3 crasher.
694
Georg Brandl24250812006-06-09 18:45:48 +0000695- The string and unicode methods startswith() and endswith() now accept
696 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
697
Brett Cannonde3b0522006-06-08 17:00:45 +0000698- Buffer objects, at the C level, never used the char buffer
699 implementation even when the char buffer for the wrapped object was
700 explicitly requested (originally returned the read or write buffer).
701 Now a TypeError is raised if the char buffer is not present but is
702 requested.
703
Georg Brandlddbaa662006-06-04 21:56:52 +0000704- Patch #1346214: Statements like "if 0: suite" are now again optimized
705 away like they were in Python 2.4.
706
Georg Brandlb7c8f542006-05-27 12:30:25 +0000707- Builtin exceptions are now full-blown new-style classes instead of
708 instances pretending to be classes, which speeds up exception handling
709 by about 80% in comparison to 2.5a2.
710
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000711- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
712 Unicode 4.1.
713
Georg Brandlf4ef1162006-05-26 18:03:31 +0000714- Patch #921466: sys.path_importer_cache is now used to cache valid and
715 invalid file paths for the built-in import machinery which leads to
716 fewer open calls on startup.
717
Tim Peters696cf432006-05-24 21:10:40 +0000718- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
719 of-2 bases. The largest speedup is for inputs with about 1000 decimal
720 digits. Conversion from non-power-of-2 bases remains quadratic-time in
721 the number of input digits (it was and remains linear-time for bases
722 2, 4, 8, 16 and 32).
723
Tim Petersb713ec22006-05-23 18:45:30 +0000724- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
725 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
726 an integer close to ``sys.maxint``. This was repaired by patch
727 #1335972, which also gives a nice speedup.
728
Richard Jonescebbefc2006-05-23 18:28:17 +0000729- Patch #1337051: reduced size of frame objects.
730
731- PyErr_NewException now accepts a tuple of base classes as its
732 "base" parameter.
733
Richard Jones7c88dcc2006-05-23 10:37:38 +0000734- Patch #876206: function call speedup by retaining allocated frame
735 objects.
736
Georg Brandl7b90e162006-05-18 07:01:27 +0000737- Bug #1462152: file() now checks more thoroughly for invalid mode
738 strings and removes a possible "U" before passing the mode to the
739 C library function.
740
Neal Norwitz1004a532006-05-15 07:17:23 +0000741- Patch #1488312, Fix memory alignment problem on SPARC in unicode
742
Neal Norwitz373f0a72006-05-15 07:04:36 +0000743- Bug #1487966: Fix SystemError with conditional expression in assignment
744
Martin v. Löwis879768d2006-05-11 13:28:43 +0000745- WindowsError now has two error code attributes: errno, which carries
746 the error values from errno.h, and winerror, which carries the error
747 values from winerror.h. Previous versions put the winerror.h values
748 (from GetLastError()) into the errno attribute.
749
Martin v. Löwis77736712006-05-04 05:51:03 +0000750- Patch #1475845: Raise IndentationError for unexpected indent.
751
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000752- Patch #1479181: split open() and file() from being aliases for each other.
753
Tim Peters44bd9862006-06-01 13:49:23 +0000754- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
755 methods were always silently ignored by dictionaries when comparing keys.
756 They are now passed through (except when using the C API function
757 ``PyDict_GetItem()``, whose semantics did not change).
758
759- Bug #1456209: In some obscure cases it was possible for a class with a
760 custom ``__eq__()`` method to confuse dict internals when class instances
761 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
762 No, you don't have any code that did this ;-)

768
769- Patch #1462338: Upgrade pyexpat to expat 2.0.0
770
Brett Cannon6ee7d012006-06-08 16:23:04 +0000771- Change binascii.hexlify to accept a read-only buffer instead of only a char
772 buffer and actually follow its documentation.
773
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000774- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
775
Nick Coghlanc649ec52006-05-29 12:43:05 +0000776- Patch #1478788 (modified version): The functional extension module has
777 been renamed to _functools and a functools Python wrapper module added.
778 This provides a home for additional function related utilities that are
779 not specifically about functional programming. See PEP 309.
780
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000781- Patch #1493701: performance enhancements for struct module.
782
Georg Brandl378d5922006-05-17 14:26:50 +0000783- Patch #1490224: time.altzone is now set correctly on Cygwin.
784
Georg Brandl8d3342b2006-05-16 07:38:27 +0000785- Patch #1435422: zlib's compress and decompress objects now have a
786 copy() method.
787
Andrew MacIntyre92913322006-06-13 15:04:24 +0000788- Patch #1454481: thread stack size is now tunable at runtime for thread
789 enabled builds on Windows and systems with Posix threads support.
790
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000791- On Win32, os.listdir now supports arbitrarily-long Unicode path names
792 (up to the system limit of 32K characters).
793
794- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
795 As a result, these functions now raise WindowsError instead of OSError.
796
Tim Peters7a822da2006-05-25 21:50:17 +0000797- ``time.clock()`` on Win64 should use the high-performance Windows
798 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
799 Windows platforms).
800
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000801- Calling Tk_Init twice is refused if the first call failed as that
802 may deadlock.
803
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000804- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
805 accept it without potentially using an uninitialized pointer.
806
807- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
808 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
809 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000810
Gregory P. Smith372b5832006-06-05 18:48:21 +0000811- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000812 [pybsddb project SF patch number 1466734]
813
Gregory P. Smith372b5832006-06-05 18:48:21 +0000814- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
815 parameter is supplied. [SF pybsddb bug #1477863]
816
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000817- bsddb: the __len__ method of a DB object has been fixed to return correct
818 results. It could previously incorrectly return 0 in some cases.
819 Fixes SF bug 1493322 (pybsddb bug 1184012).
820
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000821- bsddb: the bsddb.dbtables Modify method now raises the proper error and
822 aborts the db transaction safely when a modifier callback fails.
823 Fixes SF python patch/bug #1408584.
824
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000825- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000826 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000827 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
828 database calls that would previously deadlock. [SF python bug #775414]
829
Vinay Sajip28e57612006-07-01 10:45:20 +0000830- Patch #1446489: add support for the ZIP64 extensions to zipfile.

833 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000834
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000835Library
836-------
837
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000838- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
839 functions.
840
Martin v. Löwis3798da02006-06-17 18:44:27 +0000841- Patch #812986: Update turtle output even if not tracing.
842
Vinay Sajip28e57612006-07-01 10:45:20 +0000843- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000844 Tkinter.BaseWidget.
845
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000846- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
847
Martin v. Löwis337487e2006-06-17 09:15:14 +0000848- Patch #763580: Add name and value arguments to Tkinter variable
849 classes.
850
Georg Brandl83cc0d02006-06-14 08:50:03 +0000851- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
852 mime.types file for determining MIME types.
853
Georg Brandl2605ca82006-06-14 06:08:31 +0000854- Bug #1339007: Shelf objects now don't raise an exception in their
855 __del__ method when initialization failed.
856
Martin v. Löwisd8251432006-06-14 05:21:04 +0000857- Patch #1455898: The MBCS codec now supports the incremental mode for
858 double-byte encodings.
859
Tim Peters43898b42006-06-14 04:09:25 +0000860- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
861 guarantee that adjacent triples in the return list always describe
862 non-adjacent blocks. Previously, a pair of matching blocks could end
863 up being described by multiple adjacent triples that formed a partition
864 of the matching pair.
865
Greg Ward0e0c9f42006-06-11 16:24:11 +0000866- Bug #1498146: fix optparse to handle Unicode strings in option help,
867 description, and epilog.
868
Greg Wardd1c797e2006-06-11 14:42:41 +0000869- Bug #1366250: minor optparse documentation error.
870
Greg Ward7f547402006-06-11 00:40:49 +0000871- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
872 clarify docs.
873
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000874- The wsgiref package has been added to the standard library.
875
Nick Coghlan676725d2006-06-08 13:54:49 +0000876- The functions update_wrapper() and wraps() have been added to the functools
877 module. These make it easier to copy relevant metadata from the original
878 function when writing wrapper functions.
879
Tim Petersd6a9eef2006-06-05 01:48:21 +0000880- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
881 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000882
Martin v. Löwis3f767792006-06-04 19:36:28 +0000883- Patch #1359618: Speed up charmap encoder by using a trie structure
884 for lookup.
885
Tim Petersd609b1a2006-06-02 23:22:51 +0000886- The functions in the ``pprint`` module now sort dictionaries by key
887 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
888 if and only if its display required more than one line, although that
889 wasn't documented. The new behavior increases predictability; e.g.,
890 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
891
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000892- Patch #1497027: try HTTP digest auth before basic auth in urllib2
893 (thanks for J. J. Lee).
894
Georg Brandl2b330372006-05-28 20:23:12 +0000895- Patch #1496206: improve urllib2 handling of passwords with respect to
896 default HTTP and HTTPS ports.
897
George Yoshidaf3c65de2006-05-28 16:39:09 +0000898- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
899
Bob Ippolito7298f272006-05-23 18:43:47 +0000900- Patch #1281707: speed up gzip.readline.
901
Georg Brandlb89316f2006-05-17 15:51:16 +0000902- Patch #1180296: Two new functions were added to the locale module:
903 format_string() to get the effect of "format % items" but locale-aware,
904 and currency() to format a monetary number with currency sign.
905
Georg Brandle3a25832006-05-17 14:56:04 +0000906- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
907 and several features added, such as speed and geometry control.
908
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000909- Patch #1488881: add support for external file objects in bz2 compressed
910 tarfiles.
911
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000912- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
913 stdout arguments, making it possible to redirect input and output
914 for remote debugging.
915
916- Patch #1484695: Update the tarfile module to version 0.8. This fixes
917 a couple of issues, notably handling of long file names using the
918 GNU LONGNAME extension.
919
920- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
921 new flag when ``name`` is already the name of an option flag.
922
923- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
924 package.
925
926- Patch #1472854: make the rlcompleter.Completer class usable on non-
927 UNIX platforms.
928
929- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
930
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000931- Bug #1472827: correctly escape newlines and tabs in attribute values in
932 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000962What's New in Python 2.5 alpha 2?
963=================================
964
965*Release date: 27-APR-2006*
966
967Core and builtins
968-----------------
969
Thomas Heller1b046642006-04-18 18:51:06 +0000970- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
971 by converting these apis from macros into exported functions again:
972
973 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
974 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
975 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
976 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
977 PyRun_String Py_CompileString
978
Martin v. Löwis45294a92006-04-18 06:24:08 +0000979- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
980
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000981- All uses of PyStructSequence_InitType have been changed to initialize
982 the type objects only once, even if the interpreter is initialized
983 multiple times.
984
Neal Norwitz61546162006-04-14 05:20:28 +0000985- Bug #1454485, array.array('u') could crash the interpreter. This was
986 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
987 to unicode when it didn't make sense. 'u#' now requires a unicode string.
988
989- Py_UNICODE is unsigned. It was always documented as unsigned, but
990 due to a bug had a signed value in previous versions.
991
Tim Peters3a5e8b12006-04-11 01:44:07 +0000992- Patch #837242: ``id()`` of any Python object always gives a positive
993 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
994 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000995 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000996 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000997
Tim Peters3a5e8b12006-04-11 01:44:07 +0000998 def __hash__(self):
999 return id(self) # WRONG
1000
1001 because a hash result must be a (short) Python int but it was always
1002 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001003 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001004 was always usable as a hash value before this patch. That's no longer
1005 necessarily so.
1006
1007- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001008 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001009 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001010 #1454844)
1011
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001012- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1013 involving generators that have paused outside of any ``try`` or ``with``
1014 blocks. (In 2.5a1, a paused generator that was part of a reference
1015 cycle could not be garbage collected, regardless of whether it was
1016 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +00001018Extension Modules
1019-----------------
1020
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001021- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1022 is a macro.
1023
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001024- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1025 fails with an error condition.
1026
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001027- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1028
1029- Bug #1117761: bsddb.*open() no longer raises an exception when using
1030 the cachesize parameter.
1031
1032- Bug #1149413: bsddb.*open() no longer raises an exception when using
1033 a temporary db (file=None) with the 'n' flag to truncate on open.
1034
1035- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1036 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001037
Armin Rigoa9017c32006-04-19 11:50:27 +00001038- Patch #1062014: AF_UNIX sockets under Linux have a special
1039 abstract namespace that is now fully supported.
1040
Anthony Baxter51bcb682006-04-05 14:51:42 +00001041Library
1042-------
1043
Peter Astrand7d1d4362006-07-14 14:04:45 +00001044- Bug #1223937: subprocess.CalledProcessError reports the exit status
1045 of the process using the returncode attribute, instead of
1046 abusing errno.
1047
Tim Peters711bf302006-04-25 03:31:36 +00001048- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1049 a doctest to be skipped (the code is not run, and the expected output
1050 or exception is ignored).
1051
Nick Coghlanda2268f2006-04-24 04:37:15 +00001052- Fixed contextlib.nested to cope with exceptions being raised and
1053 caught inside exit handlers.
1054
Greg Wardab05edc2006-04-23 03:47:58 +00001055- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1056 hex, octal, or binary; add ``append_const`` action; keep going if
1057 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1058 added ``epilog`` for better help generation).
1059
Tim Peters21fbd572006-04-21 21:18:10 +00001060- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1061 called from a thread spawned as a side effect of importing a module.
1062
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001063- The pydoc module now supports documenting packages contained in
1064 .zip or .egg files.
1065
1066- The pkgutil module now has several new utility functions, such
1067 as ``walk_packages()`` to support working with packages that are either
1068 in the filesystem or zip files.
1069
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001070- The mailbox module can now modify and delete messages from
1071 mailboxes, in addition to simply reading them. Thanks to Gregory
1072 K. Johnson for writing the code, and to the 2005 Google Summer of
1073 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001074
Tim Petersc7605f22006-04-17 21:12:33 +00001075- The ``__del__`` method of class ``local`` in module ``_threading_local``
1076 returned before accomplishing any of its intended cleanup.
1077
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001078- Patch #790710: Add breakpoint command lists in pdb.
1079
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001080- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +00001082- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1083
Anthony Baxtere29002c2006-04-12 12:07:31 +00001084- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1085 Windows. Bug #1469163.
1086
Phillip J. Eby47032112006-04-11 01:07:43 +00001087- The warnings, linecache, inspect, traceback, site, and doctest modules
1088 were updated to work correctly with modules imported from zipfiles or
1089 via other PEP 302 __loader__ objects.
1090
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001091- Patch #1467770: Reduce usage of subprocess._active to processes which
1092 the application hasn't waited on.
1093
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001094- Patch #1462222: Fix Tix.Grid.
1095
Neal Norwitza31bf182006-04-09 03:35:43 +00001096- Fix exception when doing glob.glob('anything*/')
1097
Skip Montanaro262fb922006-04-21 02:31:07 +00001098- The pstats.Stats class accepts an optional stream keyword argument to
1099 direct output to an alternate file-like object.
1100

1102-----
1103
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001104- The Makefile now has a reindent target, which runs reindent.py on
1105 the library.
1106
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001107- Patch #1470875: Building Python with MS Free Compiler
1108
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001109- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001110
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001111- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1112 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001113 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001114 CXX from --with-cxx-main, see description in README.
1115
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001116- Patch #1429775: Link extension modules with the shared libpython.
1117
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001118- Fixed a libffi build problem on MIPS systems.
1119
Tim Peters8931ff12006-05-13 23:28:20 +00001120- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1121 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1122 and "%zu" for unsigned integers of type ``size_t``.
1123
Anthony Baxter51bcb682006-04-05 14:51:42 +00001124Tests
1125-----
1126
Nick Coghlanda2268f2006-04-24 04:37:15 +00001127- test_contextlib now checks contextlib.nested can cope with exceptions
1128 being raised and caught inside exit handlers.
1129
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001130- test_cmd_line now checks operation of the -m and -c command switches
1131
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001132- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1133 it separately and by hand. It also wasn't cleaning up its changes to
1134 the current Decimal context.
1135
Thomas Woutersabd08882006-04-26 15:53:30 +00001136- regrtest.py now has a -M option to run tests that test the new limits of
1137 containers, on 64-bit architectures. Running these tests is only sensible
1138 on 64-bit machines with more than two gigabytes of memory. The argument
1139 passed is the maximum amount of memory for the tests to use.

1148-------------
1149
Tim Petersb06d28c2006-05-12 01:57:59 +00001150- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1151
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001152- PEP 343: Added Context Types section to the library reference
1153 and attempted to bring other PEP 343 related documentation into
1154 line with the implementation and/or python-dev discussions.
1155
Tim Peters8dc73d22006-04-24 02:03:16 +00001156- Bug #1337990: clarified that ``doctest`` does not support examples
1157 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001160What's New in Python 2.5 alpha 1?
1161=================================
1162
Anthony Baxterebed3f62006-04-03 15:03:44 +00001163*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001164
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001165Core and builtins
1166-----------------
1167
Nick Coghlan43832302006-04-23 17:04:07 +00001168- PEP 338: -m command line switch now delegates to runpy.run_module
1169 allowing it to support modules in packages and zipfiles
1170
Martin v. Löwisc661b882006-04-20 04:54:23 +00001171- On Windows, .DLL is not an accepted file name extension for
1172 extension modules anymore; extensions are only found if they
1173 end in .PYD.
1174
Martin v. Löwisea62d252006-04-03 10:56:49 +00001175- Bug #1421664: sys.stderr.encoding is now set to the same value as
1176 sys.stdout.encoding.
1177
Neal Norwitz92e212f2006-04-03 04:48:37 +00001178- __import__ accepts keyword arguments.
1179
Georg Brandlccadf842006-03-31 18:54:53 +00001180- Patch #1460496: round() now accepts keyword arguments.
1181
Anthony Baxter262c00a2006-03-30 10:53:17 +00001182- Fixed bug #1459029 - unicode reprs were double-escaped.
1183
Hye-Shik Changd478f342006-03-23 12:32:36 +00001184- Patch #1396919: The system scope threads are reenabled on FreeBSD
1185 5.4 and later versions.
1186
Neal Norwitze98ccf62006-03-23 05:39:47 +00001187- Bug #1115379: Compiling a Unicode string with an encoding declaration
1188 now gives a SyntaxError.
1189
Georg Brandlabd1ff82006-03-18 07:59:59 +00001190- Previously, Python code had no easy way to access the contents of a
1191 cell object. Now, a ``cell_contents`` attribute has been added
1192 (closes patch #1170323).
1193
Tim Peterscf79aac2006-03-16 01:14:46 +00001194- Patch #1123430: Python's small-object allocator now returns an arena to
1195 the system ``free()`` when all memory within an arena becomes unused
1196 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1197 freed. Some applications will see a drop in virtual memory size now,
1198 especially long-running applications that, from time to time, temporarily
1199 use a large number of small objects. Note that when Python returns an
1200 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001201 platform C library will in turn return that memory to the operating system.
1202 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001203 appears to be effective at least on Microsoft C and gcc-based systems.
1204 Thanks to Evan Jones for hard work and patience.
1205
Georg Brandl533ff6f2006-03-08 18:09:27 +00001206- Patch #1434038: property() now uses the getter's docstring if there is
1207 no "doc" argument given. This makes it possible to legitimately use
1208 property() as a decorator to produce a read-only property.
1209
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001210- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1211 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1212 of requiring an int or long in slicing and a few other contexts, enabling
1213 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1214
Neal Norwitz995acdf2006-03-07 05:01:00 +00001215- Fixed various bugs reported by Coverity's Prevent tool.
1216
Brett Cannonbf364092006-03-01 04:25:17 +00001217- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1218 new exception base class, BaseException, which has a new message attribute.
1219 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1220 Raising a string exception now raises a DeprecationWarning.
1221
Thomas Woutersfb609f42006-02-28 16:37:25 +00001222- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1223 explicitly relative, using 'from .module import name' to mean 'from the same
1224 package as this module is in. Imports without dots still default to the
1225 old relative-then-absolute, unless 'from __future__ import
1226 absolute_import' is used.
1227
Brett Cannona7446e32006-02-27 23:39:10 +00001228- Properly check if 'warnings' raises an exception (usually when a filter set
1229 to "error" is triggered) when raising a warning for raising string
1230 exceptions.
1231
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001232- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001233 The name was removed from Include/code.h.
1234
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001235- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001236
Guido van Rossum1968ad32006-02-25 22:38:04 +00001237- Patch 1433928:
1238 - The copy module now "copies" function objects (as atomic objects).
1239 - dict.__getitem__ now looks for a __missing__ hook before raising
1240 KeyError.
1241
Tim Peters84ef21c2006-02-28 20:39:06 +00001242- PEP 343: with statement implemented. Needs ``from __future__ import
1243 with_statement``. Use of 'with' as a variable will generate a warning.
1244 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001245 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001246 The following objects have __context__ methods:
1247 - The built-in file type.
1248 - The thread.LockType type.
1249 - The following types defined by the threading module:
1250 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1251 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001252
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001253- Fix the encodings package codec search function to only search
1254 inside its own package. Fixes problem reported in patch #1433198.
1255
1256 Note: Codec packages should implement and register their own
1257 codec search function. PEP 100 has the details.
1258
Tim Peters9ea89d22006-06-04 03:26:02 +00001259- PEP 353: Using ``Py_ssize_t`` as the index type.
1260
1261- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1262 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1263 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1264 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1265 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001266
Neal Norwitzfc76d632006-01-10 06:03:13 +00001267- Patch #1400181, fix unicode string formatting to not use the locale.
1268 This is how string objects work. u'%f' could use , instead of .
1269 for the decimal point. Now both strings and unicode always use periods.
1270
Neal Norwitz671b9e32006-01-09 07:07:12 +00001271- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1272 configure would break checking curses.h.
1273
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001274- Bug #959576: The pwd module is now builtin. This allows Python to be
1275 built on UNIX platforms without $HOME set.
1276
Neal Norwitzc10978f2005-12-19 06:07:16 +00001277- Bug #1072182, fix some potential problems if characters are signed.
1278
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001279- Bug #889500, fix line number on SyntaxWarning for global declarations.
1280
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001281- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1282
Neal Norwitze7214a12005-12-18 05:03:17 +00001283- Support for converting hex strings to floats no longer works.
1284 This was not portable. float('0x3') now raises a ValueError.
1285
Barry Warsaw2a38a862005-12-18 01:27:35 +00001286- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001287 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001288 is now displayed in interactive prompt banner.
1289
Georg Brandlfa166682005-12-17 21:45:17 +00001290- Implementation of PEP 341 - Unification of try/except and try/finally.
1291 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001292 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001293
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001294- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1295 now encodes backslash correctly.
1296
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001297- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1298
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001299- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001300 and long longs.
1301
Neal Norwitz67715f02005-11-09 06:59:35 +00001302- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001303 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001304 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001305
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001306- Replaced most Unicode charmap codecs with new ones using the
1307 new Unicode translate string feature in the builtin charmap
1308 codec; the codecs were created from the mapping tables available
1309 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1310 encodings now include a mapping for the Apple logo)
1311
Tim Peterse3547fd2005-12-16 23:13:57 +00001312- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001313
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001314- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001315
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001316- A new AST parser implementation was completed. The abstract
1317 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001318 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001319
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001320- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001321 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1322
Neal Norwitz708e51a2005-10-03 04:48:15 +00001323- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1324
Neal Norwitz11bd1192005-10-03 00:54:56 +00001325- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1326 Provide a warning when a directory is passed on the command line.
1327
Neal Norwitz40d37812005-10-02 01:48:49 +00001328- Fix segfault with invalid coding.
1329
1330- SF bug #772896: unknown encoding results in MemoryError.
1331
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001332- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001333 supported a __len__() method which evaluated to False when the iterator
1334 was empty.
1335
Guido van Rossum630db602005-09-20 18:49:54 +00001336- On 64-bit platforms, when __len__() returns a value that cannot be
1337 represented as a C int, raise OverflowError.
1338
Skip Montanarof8948ca2005-09-19 03:54:46 +00001339- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001340 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001341
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001342- SF bug #893549: parsing keyword arguments was broken with a few format
1343 codes.
1344
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001345- Changes donated by Elemental Security to make it work on AIX 5.3
1346 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1347 bug #105470: test_pwd fails on 64bit system (Opteron).
1348
Guido van Rossum539c6622005-09-14 17:49:54 +00001349- Changes donated by Elemental Security to make it work on HP-UX 11 on
1350 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1351
Georg Brandl4550b8d2005-08-26 06:43:52 +00001352- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001353 (fixes bug #1119418).
1354
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001355- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1356
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001357- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1358 exceptions that cause a function to exit.
1359
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001360- The implementation of set() and frozenset() was revised to use its
1361 own internal data structure. Memory consumption is reduced by 1/3
1362 and there are modest speed-ups as well. The API is unchanged.
1363
Tim Petersde7990b2005-07-17 23:45:23 +00001364- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1365
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001366- SF bug #1229429: PyObject_CallMethod failed to decrement some
1367 reference counts in some error exit cases.
1368
Tim Petersecc6e6a2005-07-10 22:30:55 +00001369- SF bug #1185883: Python's small-object memory allocator took over
1370 a block managed by the platform C library whenever a realloc specified
1371 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001372 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001373 portable way to copy data from the C-managed block into Python's
1374 small-object space without risking a memory fault. Python's small-object
1375 realloc now leaves such blocks under the control of the platform C
1376 realloc.
1377
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001378- SF bug #1232517: An overflow error was not detected properly when
1379 attempting to convert a large float to an int in os.utime().
1380
Raymond Hettinger3296e692005-06-29 23:29:56 +00001381- SF bug #1224347: hex longs now print with lowercase letters just
1382 like their int counterparts.
1383
Michael W. Hudson188d4362005-06-20 16:52:57 +00001384- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1385 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1386 interpreter states; back out that fix and do a better job (see
1387 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1388 for a longer write-up of the problem).
1389
Michael W. Hudsondf888462005-06-03 14:41:55 +00001390- SF patch #1180995: marshal now uses a binary format by default when
1391 serializing floats.
1392
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001393- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1394 the routines that promise to produce IEEE 754 binary representations
1395 of floats now simply copy bytes around.
1396
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001397- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1398 278.
1399
Brett Cannonc3647ac2005-04-26 03:45:26 +00001400- patch #1109424: int, long, float, complex, and unicode now check for the
1401 proper magic slot for type conversions when subclassed. Previously the
1402 magic slot was ignored during conversion. Semantics now match the way
1403 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001404 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001405 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001406 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001407
Barry Warsawc8d907c2005-04-19 23:43:40 +00001408- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1409 NULL, now raise an AttributeError when attempting to set or delete the
1410 attribute. Previously a TypeError was raised, but this was inconsistent
1411 with the equivalent pure-Python implementation.
1412
Michael W. Hudson774479c2005-04-18 08:46:17 +00001413- It is now safe to call PyGILState_Release() before
1414 PyEval_InitThreads() (note that if there is reason to believe there
1415 are multiple threads around you still must call PyEval_InitThreads()
1416 before using the Python API; this fix is for extension modules that
1417 have no way of knowing if Python is multi-threaded yet).
1418
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001419- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1420 disabled caused a crash.
1421
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001422- Bug #1165306: instancemethod_new allowed the creation of a method
1423 with im_class == im_self == NULL, which caused a crash when called.
1424
Tim Petersecc6e6a2005-07-10 22:30:55 +00001425- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001426 fixes the crash seen in bug #1165761
1427
Raymond Hettinger96229b12005-03-11 06:49:40 +00001428- Added two new builtins, any() and all().
1429
Brett Cannon409d8f22005-03-05 06:47:57 +00001430- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001431 (e.g., ``class C(): pass`` is no longer a syntax error).
1432 Patch #1176012 added support to the 'parser' module and 'compiler' package
1433 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001434
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001435- Patch #1115086: Support PY_LONGLONG in structmember.
1436
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001437- Bug #1155938: new style classes did not check that __init__() was
1438 returning None.
1439
Tim Petersecc6e6a2005-07-10 22:30:55 +00001440- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001441 ('\') with a specific error message.
1442
Martin v. Löwisff232d72005-03-03 09:24:38 +00001443- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1444
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001445- Bug #1124295: the __name__ attribute of file objects was
1446 inadvertently made inaccessible in restricted mode.
1447
Tim Petersecc6e6a2005-07-10 22:30:55 +00001448- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001449 an ferror() call.
1450
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001451- min() and max() now support key= arguments with the same meaning as in
1452 list.sort().
1453
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001454- The peephole optimizer now performs simple constant folding in expressions:
1455 (2+3) --> (5).
1456
Raymond Hettingera422c342005-01-11 03:03:27 +00001457- set and frozenset objects can now be marshalled. SF #1098985.
1458
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001459- Bug #1077106: Poor argument checking could cause memory corruption
1460 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001461
Jeremy Hyltonab630502005-02-04 18:44:06 +00001462- The parser did not complain about future statements in illegal
1463 positions. It once again reports a syntax error if a future
1464 statement occurs after anything other than a doc string.
1465
Neil Schemenauercf52c072005-08-12 17:34:58 +00001466- Change the %s format specifier for str objects so that it returns a
1467 unicode instance if the argument is not an instance of basestring and
1468 calling __str__ on the argument returns a unicode instance.
1469
Tim Petersf4e69282006-02-27 17:15:31 +00001470- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1471 current thread state when the auto-GIL-state machinery knows about
1472 it (since the thread state is being deleted, continuing to remember it
1473 can't help, but can hurt if another thread happens to get created with
1474 the same thread id).
1475
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001476Extension Modules
1477-----------------
1478
Georg Brandl43f08a82006-03-31 18:01:16 +00001479- Patch #1380952: fix SSL objects timing out on consecutive read()s
1480
Neal Norwitz05a45592006-03-20 06:30:08 +00001481- Patch #1309579: wait3 and wait4 were added to the posix module.
1482
Anthony Baxterfa869072006-03-20 05:21:58 +00001483- Patch #1231053: The audioop module now supports encoding/decoding of alaw.

1652
Raymond Hettingerb2594052004-12-05 09:25:51 +00001653- itertools.islice() now accepts None for the start and step arguments.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001666- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1667 been renamed to have only a single underscore prefix. This was done to
1668 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001669
Nick Coghlan43832302006-04-23 17:04:07 +00001670- PEP 338: new module runpy defines a run_module function to support
1671 executing modules which provide access to source code or a code object
1672 via the PEP 302 import mechanisms.
1673
Anthony Baxter93f5b932006-04-03 08:05:07 +00001674- The email module's parsedate_tz function now sets the daylight savings

1682 in attribute values.
1683
Anthony Baxterc51ee692006-04-01 00:57:31 +00001684- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001685 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001686 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001687 module will not be built.
1688
Tim Petersc17976e2006-04-01 00:26:53 +00001689- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1690 aren't officially supported here, and trying to use them will probably
1691 raise an exception some day. But dicts have been allowed, and "mostly
1692 worked", so support for them won't go away without warning.
1693
Georg Brandl338ef7d2006-03-31 18:42:16 +00001694- Bug #1445068: getpass.getpass() can now be given an explicit stream
1695 argument to specify where to write the prompt.
1696

1712
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001713- email 4.0 package now integrated. This is largely the same as the email 3.0
1714 package that was included in Python 2.3, except that PEP 8 module names are
1715 now used (e.g. mail.message instead of email.Message). The MIME classes
1716 have been moved to a subpackage (e.g. email.mime.text instead of
1717 email.MIMEText). The old names are still supported for now. Several
1718 deprecated Message methods have been removed and lots of bugs have been
1719 fixed. More details can be found in the email package documentation.
1720
Walter Dörwald40108c92006-03-27 08:15:44 +00001721- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1722 (a subclass of tuple) that provides incremental decoders and encoders
1723 (a way to use stateful codecs without the stream API). Python functions
1724 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1725 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1726 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001728- Patch #1359365: Calling next() on a closed StringIO.String object raises
1729 a ValueError instead of a StopIteration now (like file and cString.String do).
1730 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1731 called before (like file and StringIO.StringIO do).

1807 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1808 Ronald L. Rivest offered this advice for Python:
1809
1810 "The consensus of researchers in this area (at least as
1811 expressed at the NIST Hash Function Workshop 10/31/05),
1812 is that SHA-256 is a good choice for the time being, but
1813 that research should continue, and other alternatives may
1814 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001815

1996 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001997 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001998 PEP 305.

2002 dictates.
2003 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002004 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002005 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002006 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2007 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002008 + reader now allows \r characters to be quoted (previously it only allowed
2009 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002010 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002011 + Dialect classes passed to the module are no longer instantiated by
2012 the module before being parsed (the former validation scheme required
2013 this, but the mechanism was unreliable).
2014 + The dialect registry now contains instances of the internal
2015 C-coded dialect type, rather than references to python objects.
2016 + the internal c-coded dialect type is now immutable.
2017 + register_dialect now accepts the same keyword dialect specifications
2018 as the reader and writer, allowing the user to register dialects
2019 without first creating a dialect class.
2020 + a configurable limit to the size of parsed fields has been added -
2021 previously, an unmatched quote character could result in the entire
2022 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002023 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002024 the parser field size limit (returning the former limit). The initial
2025 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002026 + A line_num attribute has been added to the reader object, which tracks
2027 the number of lines read from the source iterator. This is not
2028 the same as the number of records returned, as records can span
2029 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002030 + reader and writer objects were not being registered with the cyclic-GC.
2031 This has been fixed.
2032
Brett Cannone6539c42005-01-08 02:43:53 +00002033- _DummyThread objects in the threading module now delete self.__block that is
2034 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2035 lock primitives tend to be limited in number and thus should not be wasted on
2036 a _DummyThread object. Fixes bug #1089632.
2037
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002038- The imghdr module now detects Exif files.
2039
Raymond Hettinger6065d322004-12-20 23:51:53 +00002040- StringIO.truncate() now correctly adjusts the size attribute.
2041 (Bug #951915).
2042
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002043- locale.py now uses an updated locale alias table (built using
2044 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2045 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002046 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002047
Raymond Hettinger3557f422004-12-07 12:02:02 +00002048- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2049
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002050- the pickle module no longer accepts the deprecated None option in the
2051 args tuple returned by __reduce__().
2052
Brett Cannon84667c02004-12-07 03:25:18 +00002053- optparse now optionally imports gettext. This allows its use in setup.py.
2054
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002055- the pickle module no longer uses the deprecated bin parameter.
2056
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002057- the shelve module no longer uses the deprecated binary parameter.
2058
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002059- the pstats module no longer uses the deprecated ignore() method.
2060
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002061- the filecmp module no longer uses the deprecated use_statcache argument.
2062
Raymond Hettinger664347b2004-12-04 21:21:53 +00002063- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2064 extended or overridden by subclasses. Formerly, the subclassed method would
2065 be ignored by the rest of the module. (Bug #1078905).
2066
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002067- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002068 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002069
Walter Dörwald36733692004-12-22 12:50:50 +00002070- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2071 once when a size argument is given. This prevents a buffer overflow in the
2072 tokenizer with very long source lines.
2073
Barry Warsaw538561e2006-01-01 21:48:54 +00002074- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2075 immediately after creating the object, without any intervening
2076 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002077
Skip Montanaro05885812005-01-16 20:48:27 +00002078- The reconvert.quote function can now emit triple-quoted strings. The
2079 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002080
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002081- ``UserString.MutableString`` now supports negative indices in
2082 ``__setitem__`` and ``__delitem__``
2083
Greg Ward40407942005-03-05 02:53:17 +00002084- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2085 correctly.
2086
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002087- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2088 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2089 character even if the user has passed a size parameter to get a proper
2090 line ending. Remove the special handling of a "\r\n" that has been split
2091 between two lines.
2092
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002093- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2094 about illegal code points. The codec now supports PEP 293 style error
2095 handlers.
2096
Walter Dörwald78a78b02005-09-01 12:04:29 +00002097- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002098 from the input stream, so that the output is a byte string in the correct
2099 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002100
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002101- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2102 considering it exactly like a '*'.
2103
Walter Dörwald007f8df2005-10-09 19:42:27 +00002104- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2105 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002106
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002107- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2108
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002109- Patch #1413711: Certain patterns of differences were making difflib
2110 touch the recursion limit.
2111
Walter Dörwald58917a62006-03-31 15:26:22 +00002112- Bug #947906: An object oriented interface has been added to the calendar
2113 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002114 called as a script (e.g. via ``python -mcalendar``). Localized month and
2115 weekday names can be ouput (even if an exotic encoding is used) using
2116 special classes that use unicode.

2119-----
2120
Neal Norwitz602d3392006-03-31 08:21:40 +00002121- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2122 by using -mieee gcc option.
2123
Martin v. Löwis86d66262006-02-17 08:40:11 +00002124- Patch #1432345: Make python compile on DragonFly.
2125
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002126- Build support for Win64-AMD64 was added.
2127
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002128- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2129
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002130- Patch #881820: look for openpty and forkpty also in libbsd.
2131
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002132- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2133 The zlib module is now builtin on Windows.
2134
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002135- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2136
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002137- Bug #1189330: configure did not correctly determine the necessary
2138 value of LINKCC if python was built with GCC 4.0.
2139
Trent Mick8321b422005-07-26 02:29:21 +00002140- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2141 vulnerability in zlib 1.2.1 and 1.2.2.
2142
Brett Cannon08cd5982005-04-24 22:26:38 +00002143- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2144 flags that change binary compatibility. Changes were also made to
2145 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002146 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002147
Bob Ippolitoed233462005-03-29 13:47:59 +00002148- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2149 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2150 no longer exists). This configure patch makes things right.
2151
Martin v. Löwise2713be2005-03-08 15:03:08 +00002152- Bug #1158607: Build with --disable-unicode again.
2153
Brett Cannon46d96232005-02-16 00:07:19 +00002154- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2155 defined. Discovered as a result of not being able to build on OS X.
2156
Brett Cannon516592f2004-12-07 00:42:59 +00002157- setup.py now uses the directories specified in LDFLAGS using the -L option
2158 and in CPPFLAGS using the -I option for adding library and include
2159 directories, respectively, for compiling extension modules against. This has
2160 led to the core being compiled using the values in CPPFLAGS. It also removes
2161 the need for the special-casing of both DarwinPorts and Fink for darwin since
2162 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2163 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2164 Fink, ``-I/opt/local/include`` for DarwinPorts).
2165
Brett Cannon43802422005-02-10 20:48:03 +00002166- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2167 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2168 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2169 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002171C API
2172-----
2173
Tim Petersc9d78aa2006-03-26 23:27:58 +00002174- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2175 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2176 is obtained via the ``PyObject_`` family, it must be released via the
2177 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2178 always been officially true, but when Python's small-object allocator was
2179 introduced, an attempt was made to cater to a few extension modules
2180 discovered at the time that obtained memory via ``PyObject_New`` but
2181 released it via ``PyMem_DEL``. It's years later, and if such code still
2182 exists it will fail now (probably with segfaults, but calling wrong
2183 low-level memory management functions can yield many symptoms).
2184
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002185- Added a C API for set and frozenset objects.
2186

2188
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002189- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2190 mapping argument now. This string is used as a mapping table. Byte values
2191 greater than the length of the string and 0xFFFE are treated as undefined
2192 mappings.
