20-----------------
21
Brett Cannon19d76c52006-09-09 07:18:44 +000022- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
23 allows calling unicode() on exceptions classes directly to succeed.
24
Georg Brandlecab6232006-09-06 06:47:02 +000025- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
26 Also make sure that every exception class has __module__ set to
27 'exceptions'.
28
Georg Brandl37a9e572006-09-06 06:09:34 +000029- Bug #1550983: emit better error messages for erroneous relative
30 imports (if not in package and if beyond toplevel package).
31
Tim Peterscbdd3502006-09-05 01:47:53 +000032- Overflow checking code in integer division ran afoul of new gcc
33 optimizations. Changed to be more standard-conforming.

37
Neal Norwitzd3da7d32006-09-05 01:54:06 +000038- Patch #1546288: fix seg fault in dict_equal due to ref counting bug.
39
Neal Norwitz29a5fdb2006-09-05 02:21:38 +000040- The return tuple from str.rpartition(sep) is (tail, sep, head) where
41 head is the original string if sep was not found.
42
Neal Norwitz3b3aae02006-09-05 03:56:01 +000043- Bug #1520864: unpacking singleton tuples in list comprehensions and
44 generator expressions (x for x, in ... ) works again. Fixing this problem
45 required changing the .pyc magic number. This means that .pyc files
46 generated before 2.5c2 will be regenerated.

Guido van Rossumc69ac252006-08-10 18:09:25 +0000128What's New in Python 2.5 release candidate 1?

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000132
133Core and builtins
134-----------------
135
Neal Norwitz24b6f202006-09-05 04:43:56 +0000136- Fix infinite recursion when subclassing long and overriding __hash__.
137
138- Fix concatenation (+=) of long strings.
139
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000140- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000141 compared equal or unequal to a string and a UnicodeDecodeError
142 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000143
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000144 Instead, the equal (==) and unequal (!=) comparison operators will
145 now issue a UnicodeWarning and interpret the two objects as
146 unequal. The UnicodeWarning can be filtered as desired using
147 the warning framework, e.g. silenced completely, turned into an
148 exception, logged, etc.
149
150 Note that compare operators other than equal and unequal will still
151 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000152
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000153- Fix segfault when doing string formatting on subclasses of long.
154
155- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
156 with new-style classes.
157
158- Fix bug related to __len__ functions returning negative values with
159 classic classes.
160
161- Patch #1538606, Fix __index__() clipping. There were some problems
162 discovered with the API and how integers that didn't fit into Py_ssize_t
163 were handled. This patch attempts to provide enough alternatives
164 to effectively use __index__.
165
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000166- Bug #1536021: __hash__ may now return long int; the final hash
167 value is obtained by invoking hash on the long int.
168
Thomas Hellerab1049c2006-08-08 17:37:00 +0000169- Bug #1536786: buffer comparison could emit a RuntimeWarning.
170
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000171- Bug #1535165: fixed a segfault in input() and raw_input() when
172 sys.stdin is closed.
173
Thomas Heller74d36f02006-08-04 18:17:40 +0000174- On Windows, the PyErr_Warn function is now exported from
175 the Python dll again.
176
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000177- Bug #1191458: tracing over for loops now produces a line event
178 on each iteration. Fixing this problem required changing the .pyc
179 magic number. This means that .pyc files generated before 2.5c1
180 will be regenerated.
181
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000182- Bug #1333982: string/number constants were inappropriately stored
183 in the byte code and co_consts even if they were not used, ie
184 immediately popped off the stack.
185
Georg Brandle9462c72006-08-04 18:03:37 +0000186- Fixed a reference-counting problem in property().

189Library
190-------
191
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000192- Fix a bug in the ``compiler`` package that caused invalid code to be
193 generated for generator expressions.
194
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000195- The distutils version has been changed to 2.5.0. The change to
196 keep it programmatically in sync with the Python version running
197 the code (introduced in 2.5b3) has been reverted. It will continue
198 to be maintained manually as static string literal.
199
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000200- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000201 and this cannot be converted to the required C type, an exception is
202 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000203 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000204
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000205- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000206 an exception.
207
Tim Peterscbdd3502006-09-05 01:47:53 +0000208- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000209 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000210 workarounds for clocks with low resolution, to stop the code yielding
211 duplicate UUIDs.
212
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000213- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
214 before raising SystemExit, allowing IDLE to honor quit() and exit().
215
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000216- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
217
Georg Brandl7a1af772006-08-14 21:55:28 +0000218- Patch #1536071: trace.py should now find the full module name of a
219 file correctly even on Windows.
220
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000221- logging's atexit hook now runs even if the rest of the module has
222 already been cleaned up.
223
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000224- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000225
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000226- Bug #1531405, format_exception no longer raises an exception if
227 str(exception) raised an exception.
228
Neil Schemenauer06ded092006-08-04 16:20:30 +0000229- Fix a bug in the ``compiler`` package that caused invalid code to be
230 generated for nested functions.

241 raises the correct exceptions.
242
Thomas Heller1ce433e2006-08-14 16:20:04 +0000243- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
244 '-no-stack-protector' compiler flag for OpenBSD has been removed.
245
Thomas Heller86720042006-08-14 11:17:48 +0000246- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
247 uses the _as_parameter_ attribute when objects are passed to foreign
248 function calls. The ctypes version number was changed to 1.0.1.
249
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000250- Bug #1530559, struct.pack raises TypeError where it used to convert.
251 Passing float arguments to struct.pack when integers are expected
252 now triggers a DeprecationWarning.
253
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000254

302Core and builtins
303-----------------
304
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000305- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000306 returned a long (see PEP 353).
307
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000308- Bug #1515471: string.replace() accepts character buffers again.
309
Neal Norwitz07aadb12006-07-30 06:55:48 +0000310- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
311 This provides the proper warning for struct.pack().
312 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
313
Neal Norwitz0d62a062006-07-30 06:53:31 +0000314- Patch #1531113: Fix augmented assignment with yield expressions.
315 Also fix a SystemError when trying to assign to yield expressions.
316
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000317- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
318 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
319 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
320 excessive filesystem operations during imports.
321
Tim Petersbc24eee2006-07-27 01:14:53 +0000322- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
323 operations on signed longs that are formally undefined by C.
324 Unfortunately, at least one compiler now cares about that, so complicated
325 the code to make that compiler happy again.
326
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000327- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
328
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000329- Patch #1232023: Stop including current directory in search
330 path on Windows.
331
Neal Norwitze1fdb322006-07-21 05:32:28 +0000332- Fix some potential crashes found with failmalloc.
333
Neal Norwitze7563102006-07-17 01:00:16 +0000334- Fix warnings reported by Klocwork's static analysis tool.
335
Neal Norwitz84be93b2006-07-16 01:50:38 +0000336- Bug #1512814, Fix incorrect lineno's when code within a function
337 had more than 255 blank lines.
338
Georg Brandl9dceedb2006-07-12 15:31:17 +0000339- Patch #1521179: Python now accepts the standard options ``--help`` and
340 ``--version`` as well as ``/?`` on Windows.
341
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000342- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000343 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000344 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000345
Tim Peters112aad32006-07-19 00:03:19 +0000346- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000347 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000348 new ``sys._current_frames()`` returns a dictionary with one entry,
349 mapping the faux "thread id" 0 to the current frame.
350
Ronald Oussoren3075e162006-07-25 20:28:55 +0000351- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

355-------
356
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000357- Correction of patch #1455898: In the mbcs decoder, set final=False
358 for stream decoder, but final=True for the decode function.
359
Georg Brandl07fec3a2006-08-01 18:49:24 +0000360- os.urandom no longer masks unrelated exceptions like SystemExit or
361 KeyboardInterrupt.
362
Tim Peters4643c2f2006-08-10 22:45:34 +0000363- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000364 shutil.copytree on Windows
365
Georg Brandle34ac7c2006-07-30 11:07:23 +0000366- Bug #1002398: The documentation for os.path.sameopenfile now correctly
367 refers to file descriptors, not file objects.
368
Tim Peterscbdd3502006-09-05 01:47:53 +0000369- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000370 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000371 #1513611, and probably others.
372
Georg Brandledd9b0d2006-07-29 09:33:26 +0000373- Bug #1441397: The compiler module now recognizes module and function
374 docstrings correctly as it did in Python 2.4.
375
Tim Peters6f681472006-07-27 23:44:37 +0000376- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
377 lost that tests are sorted by name before being run. This rarely
378 matters for well-written tests, but can create baffling symptoms if
379 side effects from one test to the next affect outcomes. ``DocTestFinder``
380 has been changed to sort the list of tests it returns.
381
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000382- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000383 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000384
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000385- Bug #978833: Really close underlying socket in _socketobject.close.
386
Georg Brandldb232dc2006-08-20 13:15:43 +0000387- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
388 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000389
Georg Brandlcf0c1722006-07-26 07:23:32 +0000390- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
391 to recursive calls and call it with the failing package name.
392
Martin v. Löwis0b483032006-07-25 09:53:12 +0000393- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
394
Georg Brandlc13c34c2006-07-24 14:09:56 +0000395- Patch #1515343: Fix printing of deprecated string exceptions with a
396 value in the traceback module.
397
Greg Ward48fae7a2006-07-23 16:05:51 +0000398- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
399
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000400- Patch #1524429: Use repr() instead of backticks in Tkinter again.
401
Brett Cannoncaebe222006-07-18 04:41:36 +0000402- Bug #1520914: Change time.strftime() to accept a zero for any position in its
403 argument tuple. For arguments where zero is illegal, the value is forced to
404 the minimum value that is correct. This is to support an undocumented but
405 common way people used to fill in inconsequential information in the time
406 tuple pre-2.4.
407
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000408- Patch #1220874: Update the binhex module for Mach-O.
409
Barry Warsawb110bad2006-07-21 14:51:07 +0000410- The email package has improved RFC 2231 support, specifically for
411 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
412 (name*0=<blah>) parameter continuations. This may change the types of
413 values returned from email.message.Message.get_param() and friends.
414 Specifically in some cases where non-encoded continuations were used,
415 get_param() used to return a 3-tuple of (None, None, string) whereas now it
416 will just return the string (since non-encoded continuations don't have
417 charset and language parts).
418
419 Also, whereas % values were decoded in all parameter continuations, they are
420 now only decoded in encoded parameter parts.
421
Ronald Oussoren3075e162006-07-25 20:28:55 +0000422- Bug #1517990: IDLE keybindings on MacOS X now work correctly
423
424- Bug #1517996: IDLE now longer shows the default Tk menu when a
425 path browser, class browser or debugger is the frontmost window on MacOS X
426
Barry Warsaw00decd72006-07-27 23:43:15 +0000427- Patch #1520294: Support for getset and member descriptors in types.py,
428 inspect.py, and pydoc.py. Specifically, this allows for querying the type
429 of an object against these built-in types and more importantly, for getting
430 their docstrings printed in the interactive interpreter's help() function.

434-----------------
435
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000436- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
437 a socket operation on a socket with a timeout, the exception will be
438 caught correctly. Previously, the exception was not caught.
439
Thomas Heller1393d6a2006-07-28 21:43:20 +0000440- Patch #1529514: The _ctypes extension is now compiled on more
441 openbsd target platforms.
442
Tim Peters9cab5932006-07-28 00:30:00 +0000443- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
444 a memory leak, affecting pickles and deep copies.
445
Tim Petersbc24eee2006-07-27 01:14:53 +0000446- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000447 Paul Eggert.
448
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000449- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
450
Thomas Hellerce049a02006-07-14 17:51:14 +0000451- Patch #1521817: Index range checking on ctypes arrays containing
452 exactly one element enabled again. This allows iterating over these
453 arrays, without the need to check the array size before.
454
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000455- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000456 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000457 /dev/null in certain cases; this is now fixed.
458
Thomas Heller47d7a062006-07-12 08:43:47 +0000459- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
460 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000461
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000462- Because of a misspelled preprocessor symbol, ctypes was always
463 compiled without thread support; this is now fixed.
464
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000465- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
466 methods now allow their database parameter to be None as the
467 sleepycat API allows.
468
Matt Flemingec926502006-07-28 11:27:27 +0000469- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
470 bluetooth API compared with Linux and FreeBSD.
471
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000472Tests
473-----
474
475- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
476 how long the test file should take to play. Now accepts taking 2.93 secs
477 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
478
Georg Brandl4793aa32006-07-28 18:31:39 +0000479- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
480 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
481 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000488Mac
489---
490
491- PythonLauncher now works correctly when the path to the script contains
492 characters that are treated specially by the shell (such as quotes).
493
494- Bug #1527397: PythonLauncher now launches scripts with the working directory
495 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000496 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000497 expect.

505Core and builtins
506-----------------
507
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000508- Bug #1441486: The literal representation of -(sys.maxint - 1)
509 again evaluates to a int object, not a long.
510
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000511- Bug #1501934: The scope of global variables that are locally assigned
512 using augmented assignment is now correctly determined.
513
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000514- Bug #927248: Recursive method-wrapper objects can now safely
515 be released.
516
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000517- Bug #1417699: Reject locale-specific decimal point in float()
518 and atof().
519
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000520- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
521 omit a default "error" argument for NULL pointer. This allows
522 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000523
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000524- Bug #1519018: 'as' is now validated properly in import statements.
525
Neal Norwitz28746ab2006-07-09 22:14:42 +0000526- On 64 bit systems, int literals that use less than 64 bits are
527 now ints rather than longs.
528
Neal Norwitzed657552006-07-10 00:04:44 +0000529- Bug #1512814, Fix incorrect lineno's when code at module scope
530 started after line 256.
531
Tim Peters32a83612006-07-10 21:08:24 +0000532- New function ``sys._current_frames()`` returns a dict mapping thread
533 id to topmost thread stack frame. This is for expert use, and is
534 especially useful for debugging application deadlocks. The functionality
535 was previously available in Fazal Majid's ``threadframe`` extension
536 module, but it wasn't possible to do this in a wholly threadsafe way from
537 an extension.

546
Tim Peters32a83612006-07-10 21:08:24 +0000547- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000548 environment variable to be set in order to the SDK environment
549 for finding the compiler, include files, etc.

554
Thomas Woutersadd19112006-07-05 11:03:49 +0000555- string.Template() now correctly handles tuple-values. Previously,
556 multi-value tuples would raise an exception and single-value tuples would
557 be treated as the value they contain, instead.
558
Martin v. Löwisede77f52006-07-03 13:01:35 +0000559- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
560 even if some data are received.
561
Martin v. Löwis45482392006-07-03 12:28:58 +0000562- Bug #1267547: Put proper recursive setup.py call into the

566 degrees and radians.
567
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000568- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000569 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000570
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000571- Bug #1514703: Only setup canvas window in turtle when the canvas
572 is created.
573
Martin v. Löwis7596e832006-07-01 15:33:37 +0000574- Bug #1513223: .close() of a _socketobj now releases the underlying
575 socket again, which then gets closed as it becomes unreferenced.
576
Fred Drake10497c82006-06-29 02:57:48 +0000577- Bug #1504333: Make sgmllib support angle brackets in quoted
578 attribute values.
579
580- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
581 sgmllib ('[' and ']' were not accepted).
582
Georg Brandl1be63af2006-06-28 20:23:25 +0000583- Fix a bug in the turtle module's end_fill function.
584
Brett Cannon53ab5b72006-06-22 16:49:14 +0000585- Bug #1510580: The 'warnings' module improperly required that a Warning
586 category be either a types.ClassType and a subclass of Warning. The proper
587 check is just that it is a subclass with Warning as the documentation states.
588
Georg Brandlad29e632006-06-21 17:45:17 +0000589- The compiler module now correctly compiles the new try-except-finally
590 statement (bug #1509132).
591
Neal Norwitz60373cd2006-06-22 06:30:50 +0000592- The wsgiref package is now installed properly on Unix.
593
Vinay Sajip28e57612006-07-01 10:45:20 +0000594- A bug was fixed in logging.config.fileConfig() which caused a crash on
595 shutdown when fileConfig() was called multiple times.
596
Gerhard Häring762fbd32006-07-02 17:48:30 +0000597- The sqlite3 module did cut off data from the SQLite database at the first
598 null character before sending it to a custom converter. This has been fixed
599 now.

603
Tim Peters112aad32006-07-19 00:03:19 +0000604- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
605 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
606 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000607
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000608- Assigning None to pointer type fields in ctypes structures possible
609 overwrote the wrong fields, this is fixed now.
610
611- Fixed a segfault in _ctypes when ctypes.wintypes were imported
612 on non-Windows platforms.
613
614- Bug #1518190: The ctypes.c_void_p constructor now accepts any
615 integer or long, without range checking.
616
617- Patch #1517790: It is now possible to use custom objects in the ctypes
618 foreign function argtypes sequence as long as they provide a from_param
619 method, no longer is it required that the object is a ctypes type.
620
621- The '_ctypes' extension module now works when Python is configured
622 with the --without-threads option.
623
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000624- Bug #1513646: os.access on Windows now correctly determines write
625 access, again.
626
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000627- Bug #1512695: cPickle.loads could crash if it was interrupted with
628 a KeyboardInterrupt.
629
Neal Norwitza12aa882006-07-06 06:45:08 +0000630- Bug #1296433: parsing XML with a non-default encoding and
631 a CharacterDataHandler could crash the interpreter in pyexpat.
632
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000633- Patch #1516912: improve Modules support for OpenVMS.

636-----
637
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000638- Automate Windows build process for the Win64 SSL module.
639
Tim Peters32a83612006-07-10 21:08:24 +0000640- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000641 Previously, the slight difference could cause compilation errors of the
642 'zlib' module on systems with more than one version of zlib.
643
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000644- The MSI compileall step was fixed to also support a TARGETDIR
645 with spaces in it.
646
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000647- Bug #1517388: sqlite3.dll is now installed on Windows independent
648 of Tcl/Tk.
649
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000650- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000651 trying to be installed even though it's empty.

654-----
655
656- Call os.waitpid() at the end of tests that spawn child processes in order
657 to minimize resources (zombies).

Nick Coghlan2d792252006-07-06 13:47:18 +0000662- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
663 documentation for the warnings module.
664
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000665- Patch #1509163: MS Toolkit Compiler no longer available.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000672
Anthony Baxterd1136802006-06-19 12:04:15 +0000673*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000674
675Core and builtins
676-----------------
677
Georg Brandla56b9152006-06-19 06:35:54 +0000678- Patch #1507676: Error messages returned by invalid abstract object operations
679 (such as iterating over an integer) have been improved and now include the
680 type of the offending object to help with debugging.
681
Brett Cannonea3912b2006-06-13 21:46:41 +0000682- Bug #992017: A classic class that defined a __coerce__() method that returned
683 its arguments swapped would infinitely recurse and segfault the interpreter.
684
Neal Norwitz909eb122006-06-12 02:13:21 +0000685- Fix the socket tests so they can be run concurrently.
686
Neal Norwitzb9845e72006-06-12 02:11:18 +0000687- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000688 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000689
Brett Cannon22565aa2006-06-09 22:31:23 +0000690- Bug #532646: object.__call__() will continue looking for the __call__
691 attribute on objects until one without one is found. This leads to recursion
692 when you take a class and set its __call__ attribute to an instance of the
693 class. Originally fixed for classic classes, but this fix is for new-style.
694 Removes the infinite_rec_3 crasher.
695
Georg Brandl24250812006-06-09 18:45:48 +0000696- The string and unicode methods startswith() and endswith() now accept
697 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
698
Brett Cannonde3b0522006-06-08 17:00:45 +0000699- Buffer objects, at the C level, never used the char buffer
700 implementation even when the char buffer for the wrapped object was
701 explicitly requested (originally returned the read or write buffer).
702 Now a TypeError is raised if the char buffer is not present but is
703 requested.
704
Georg Brandlddbaa662006-06-04 21:56:52 +0000705- Patch #1346214: Statements like "if 0: suite" are now again optimized
706 away like they were in Python 2.4.
707
Georg Brandlb7c8f542006-05-27 12:30:25 +0000708- Builtin exceptions are now full-blown new-style classes instead of
709 instances pretending to be classes, which speeds up exception handling
710 by about 80% in comparison to 2.5a2.
711
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000712- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
713 Unicode 4.1.
714
Georg Brandlf4ef1162006-05-26 18:03:31 +0000715- Patch #921466: sys.path_importer_cache is now used to cache valid and
716 invalid file paths for the built-in import machinery which leads to
717 fewer open calls on startup.
718
Tim Peters696cf432006-05-24 21:10:40 +0000719- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
720 of-2 bases. The largest speedup is for inputs with about 1000 decimal
721 digits. Conversion from non-power-of-2 bases remains quadratic-time in
722 the number of input digits (it was and remains linear-time for bases
723 2, 4, 8, 16 and 32).
724
Tim Petersb713ec22006-05-23 18:45:30 +0000725- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
726 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
727 an integer close to ``sys.maxint``. This was repaired by patch
728 #1335972, which also gives a nice speedup.
729
Richard Jonescebbefc2006-05-23 18:28:17 +0000730- Patch #1337051: reduced size of frame objects.
731
732- PyErr_NewException now accepts a tuple of base classes as its
733 "base" parameter.
734
Richard Jones7c88dcc2006-05-23 10:37:38 +0000735- Patch #876206: function call speedup by retaining allocated frame
736 objects.
737
Georg Brandl7b90e162006-05-18 07:01:27 +0000738- Bug #1462152: file() now checks more thoroughly for invalid mode
739 strings and removes a possible "U" before passing the mode to the
740 C library function.
741
Neal Norwitz1004a532006-05-15 07:17:23 +0000742- Patch #1488312, Fix memory alignment problem on SPARC in unicode
743
Neal Norwitz373f0a72006-05-15 07:04:36 +0000744- Bug #1487966: Fix SystemError with conditional expression in assignment
745
Martin v. Löwis879768d2006-05-11 13:28:43 +0000746- WindowsError now has two error code attributes: errno, which carries
747 the error values from errno.h, and winerror, which carries the error
748 values from winerror.h. Previous versions put the winerror.h values
749 (from GetLastError()) into the errno attribute.
750
Martin v. Löwis77736712006-05-04 05:51:03 +0000751- Patch #1475845: Raise IndentationError for unexpected indent.
752
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000753- Patch #1479181: split open() and file() from being aliases for each other.
754
Tim Peters44bd9862006-06-01 13:49:23 +0000755- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
756 methods were always silently ignored by dictionaries when comparing keys.
757 They are now passed through (except when using the C API function
758 ``PyDict_GetItem()``, whose semantics did not change).
759
760- Bug #1456209: In some obscure cases it was possible for a class with a
761 custom ``__eq__()`` method to confuse dict internals when class instances
762 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
763 No, you don't have any code that did this ;-)

769
770- Patch #1462338: Upgrade pyexpat to expat 2.0.0
771
Brett Cannon6ee7d012006-06-08 16:23:04 +0000772- Change binascii.hexlify to accept a read-only buffer instead of only a char
773 buffer and actually follow its documentation.
774
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000775- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
776
Nick Coghlanc649ec52006-05-29 12:43:05 +0000777- Patch #1478788 (modified version): The functional extension module has
778 been renamed to _functools and a functools Python wrapper module added.
779 This provides a home for additional function related utilities that are
780 not specifically about functional programming. See PEP 309.
781
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000782- Patch #1493701: performance enhancements for struct module.
783
Georg Brandl378d5922006-05-17 14:26:50 +0000784- Patch #1490224: time.altzone is now set correctly on Cygwin.
785
Georg Brandl8d3342b2006-05-16 07:38:27 +0000786- Patch #1435422: zlib's compress and decompress objects now have a
787 copy() method.
788
Andrew MacIntyre92913322006-06-13 15:04:24 +0000789- Patch #1454481: thread stack size is now tunable at runtime for thread
790 enabled builds on Windows and systems with Posix threads support.
791
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000792- On Win32, os.listdir now supports arbitrarily-long Unicode path names
793 (up to the system limit of 32K characters).
794
795- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
796 As a result, these functions now raise WindowsError instead of OSError.
797
Tim Peters7a822da2006-05-25 21:50:17 +0000798- ``time.clock()`` on Win64 should use the high-performance Windows
799 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
800 Windows platforms).
801
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000802- Calling Tk_Init twice is refused if the first call failed as that
803 may deadlock.
804
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000805- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
806 accept it without potentially using an uninitialized pointer.
807
808- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
809 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
810 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000811
Gregory P. Smith372b5832006-06-05 18:48:21 +0000812- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000813 [pybsddb project SF patch number 1466734]
814
Gregory P. Smith372b5832006-06-05 18:48:21 +0000815- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
816 parameter is supplied. [SF pybsddb bug #1477863]
817
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000818- bsddb: the __len__ method of a DB object has been fixed to return correct
819 results. It could previously incorrectly return 0 in some cases.
820 Fixes SF bug 1493322 (pybsddb bug 1184012).
821
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000822- bsddb: the bsddb.dbtables Modify method now raises the proper error and
823 aborts the db transaction safely when a modifier callback fails.
824 Fixes SF python patch/bug #1408584.
825
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000826- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000827 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000828 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
829 database calls that would previously deadlock. [SF python bug #775414]
830
Vinay Sajip28e57612006-07-01 10:45:20 +0000831- Patch #1446489: add support for the ZIP64 extensions to zipfile.

Walter Dörwald4994d952006-06-19 08:07:50 +0000833- Patch #1506645: add Python wrappers for the curses functions
834 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000835
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000836Library
837-------
838
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000839- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
840 functions.
841
Martin v. Löwis3798da02006-06-17 18:44:27 +0000842- Patch #812986: Update turtle output even if not tracing.
843
Vinay Sajip28e57612006-07-01 10:45:20 +0000844- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000845 Tkinter.BaseWidget.
846
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000847- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
848
Martin v. Löwis337487e2006-06-17 09:15:14 +0000849- Patch #763580: Add name and value arguments to Tkinter variable
850 classes.
851
Georg Brandl83cc0d02006-06-14 08:50:03 +0000852- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
853 mime.types file for determining MIME types.
854
Georg Brandl2605ca82006-06-14 06:08:31 +0000855- Bug #1339007: Shelf objects now don't raise an exception in their
856 __del__ method when initialization failed.
857
Martin v. Löwisd8251432006-06-14 05:21:04 +0000858- Patch #1455898: The MBCS codec now supports the incremental mode for
859 double-byte encodings.
860
Tim Peters43898b42006-06-14 04:09:25 +0000861- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
862 guarantee that adjacent triples in the return list always describe
863 non-adjacent blocks. Previously, a pair of matching blocks could end
864 up being described by multiple adjacent triples that formed a partition
865 of the matching pair.
866
Greg Ward0e0c9f42006-06-11 16:24:11 +0000867- Bug #1498146: fix optparse to handle Unicode strings in option help,
868 description, and epilog.
869
Greg Wardd1c797e2006-06-11 14:42:41 +0000870- Bug #1366250: minor optparse documentation error.
871
Greg Ward7f547402006-06-11 00:40:49 +0000872- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
873 clarify docs.
874
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000875- The wsgiref package has been added to the standard library.
876
Nick Coghlan676725d2006-06-08 13:54:49 +0000877- The functions update_wrapper() and wraps() have been added to the functools
878 module. These make it easier to copy relevant metadata from the original
879 function when writing wrapper functions.
880
Tim Petersd6a9eef2006-06-05 01:48:21 +0000881- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
882 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000883
Martin v. Löwis3f767792006-06-04 19:36:28 +0000884- Patch #1359618: Speed up charmap encoder by using a trie structure
885 for lookup.
886
Tim Petersd609b1a2006-06-02 23:22:51 +0000887- The functions in the ``pprint`` module now sort dictionaries by key
888 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
889 if and only if its display required more than one line, although that
890 wasn't documented. The new behavior increases predictability; e.g.,
891 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
892
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000893- Patch #1497027: try HTTP digest auth before basic auth in urllib2
894 (thanks for J. J. Lee).
895
Georg Brandl2b330372006-05-28 20:23:12 +0000896- Patch #1496206: improve urllib2 handling of passwords with respect to
897 default HTTP and HTTPS ports.
898
George Yoshidaf3c65de2006-05-28 16:39:09 +0000899- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
900
Bob Ippolito7298f272006-05-23 18:43:47 +0000901- Patch #1281707: speed up gzip.readline.
902
Georg Brandlb89316f2006-05-17 15:51:16 +0000903- Patch #1180296: Two new functions were added to the locale module:
904 format_string() to get the effect of "format % items" but locale-aware,
905 and currency() to format a monetary number with currency sign.
906
Georg Brandle3a25832006-05-17 14:56:04 +0000907- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
908 and several features added, such as speed and geometry control.
909
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000910- Patch #1488881: add support for external file objects in bz2 compressed
911 tarfiles.
912
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000913- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
914 stdout arguments, making it possible to redirect input and output
915 for remote debugging.
916
917- Patch #1484695: Update the tarfile module to version 0.8. This fixes
918 a couple of issues, notably handling of long file names using the
919 GNU LONGNAME extension.
920
921- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
922 new flag when ``name`` is already the name of an option flag.
923
924- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
925 package.
926
927- Patch #1472854: make the rlcompleter.Completer class usable on non-
928 UNIX platforms.
929
930- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
931
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000932- Bug #1472827: correctly escape newlines and tabs in attribute values in
933 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000963What's New in Python 2.5 alpha 2?
964=================================
965
966*Release date: 27-APR-2006*
967
968Core and builtins
969-----------------
970
Thomas Heller1b046642006-04-18 18:51:06 +0000971- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
972 by converting these apis from macros into exported functions again:
973
974 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
975 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
976 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
977 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
978 PyRun_String Py_CompileString
979
Martin v. Löwis45294a92006-04-18 06:24:08 +0000980- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
981
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000982- All uses of PyStructSequence_InitType have been changed to initialize
983 the type objects only once, even if the interpreter is initialized
984 multiple times.
985
Neal Norwitz61546162006-04-14 05:20:28 +0000986- Bug #1454485, array.array('u') could crash the interpreter. This was
987 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
988 to unicode when it didn't make sense. 'u#' now requires a unicode string.
989
990- Py_UNICODE is unsigned. It was always documented as unsigned, but
991 due to a bug had a signed value in previous versions.
992
Tim Peters3a5e8b12006-04-11 01:44:07 +0000993- Patch #837242: ``id()`` of any Python object always gives a positive
994 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
995 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000996 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000997 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000998
Tim Peters3a5e8b12006-04-11 01:44:07 +0000999 def __hash__(self):
1000 return id(self) # WRONG
1001
1002 because a hash result must be a (short) Python int but it was always
1003 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001004 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001005 was always usable as a hash value before this patch. That's no longer
1006 necessarily so.
1007
1008- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001009 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001010 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001011 #1454844)
1012
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001013- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1014 involving generators that have paused outside of any ``try`` or ``with``
1015 blocks. (In 2.5a1, a paused generator that was part of a reference
1016 cycle could not be garbage collected, regardless of whether it was
1017 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001018
Anthony Baxter51bcb682006-04-05 14:51:42 +00001019Extension Modules

1021
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001022- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1023 is a macro.
1024
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001025- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1026 fails with an error condition.
1027
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001028- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1029
1030- Bug #1117761: bsddb.*open() no longer raises an exception when using
1031 the cachesize parameter.
1032
1033- Bug #1149413: bsddb.*open() no longer raises an exception when using
1034 a temporary db (file=None) with the 'n' flag to truncate on open.
1035
1036- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1037 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001038
Armin Rigoa9017c32006-04-19 11:50:27 +00001039- Patch #1062014: AF_UNIX sockets under Linux have a special
1040 abstract namespace that is now fully supported.
1041
Anthony Baxter51bcb682006-04-05 14:51:42 +00001042Library
1043-------
1044
Peter Astrand7d1d4362006-07-14 14:04:45 +00001045- Bug #1223937: subprocess.CalledProcessError reports the exit status
1046 of the process using the returncode attribute, instead of
1047 abusing errno.
1048
Tim Peters711bf302006-04-25 03:31:36 +00001049- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1050 a doctest to be skipped (the code is not run, and the expected output
1051 or exception is ignored).
1052
Nick Coghlanda2268f2006-04-24 04:37:15 +00001053- Fixed contextlib.nested to cope with exceptions being raised and
1054 caught inside exit handlers.
1055
Greg Wardab05edc2006-04-23 03:47:58 +00001056- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1057 hex, octal, or binary; add ``append_const`` action; keep going if
1058 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1059 added ``epilog`` for better help generation).
1060
Tim Peters21fbd572006-04-21 21:18:10 +00001061- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1062 called from a thread spawned as a side effect of importing a module.
1063
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001064- The pydoc module now supports documenting packages contained in
1065 .zip or .egg files.
1066
1067- The pkgutil module now has several new utility functions, such
1068 as ``walk_packages()`` to support working with packages that are either
1069 in the filesystem or zip files.
1070
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001071- The mailbox module can now modify and delete messages from
1072 mailboxes, in addition to simply reading them. Thanks to Gregory
1073 K. Johnson for writing the code, and to the 2005 Google Summer of
1074 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001075
Tim Petersc7605f22006-04-17 21:12:33 +00001076- The ``__del__`` method of class ``local`` in module ``_threading_local``
1077 returned before accomplishing any of its intended cleanup.
1078
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001079- Patch #790710: Add breakpoint command lists in pdb.
1080
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001081- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1082
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001083- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1084
Anthony Baxtere29002c2006-04-12 12:07:31 +00001085- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1086 Windows. Bug #1469163.
1087
Phillip J. Eby47032112006-04-11 01:07:43 +00001088- The warnings, linecache, inspect, traceback, site, and doctest modules
1089 were updated to work correctly with modules imported from zipfiles or
1090 via other PEP 302 __loader__ objects.
1091
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001092- Patch #1467770: Reduce usage of subprocess._active to processes which
1093 the application hasn't waited on.
1094
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001095- Patch #1462222: Fix Tix.Grid.
1096
Neal Norwitza31bf182006-04-09 03:35:43 +00001097- Fix exception when doing glob.glob('anything*/')
1098
Skip Montanaro262fb922006-04-21 02:31:07 +00001099- The pstats.Stats class accepts an optional stream keyword argument to
1100 direct output to an alternate file-like object.
1101

1103-----
1104
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001105- The Makefile now has a reindent target, which runs reindent.py on
1106 the library.
1107
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001108- Patch #1470875: Building Python with MS Free Compiler
1109
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001110- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001111
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001112- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1113 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001114 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001115 CXX from --with-cxx-main, see description in README.
1116
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001117- Patch #1429775: Link extension modules with the shared libpython.
1118
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001119- Fixed a libffi build problem on MIPS systems.
1120
Tim Peters8931ff12006-05-13 23:28:20 +00001121- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1122 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1123 and "%zu" for unsigned integers of type ``size_t``.
1124
Anthony Baxter51bcb682006-04-05 14:51:42 +00001125Tests
1126-----
1127
Nick Coghlanda2268f2006-04-24 04:37:15 +00001128- test_contextlib now checks contextlib.nested can cope with exceptions
1129 being raised and caught inside exit handlers.
1130
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001131- test_cmd_line now checks operation of the -m and -c command switches
1132
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001133- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1134 it separately and by hand. It also wasn't cleaning up its changes to
1135 the current Decimal context.
1136
Thomas Woutersabd08882006-04-26 15:53:30 +00001137- regrtest.py now has a -M option to run tests that test the new limits of
1138 containers, on 64-bit architectures. Running these tests is only sensible
1139 on 64-bit machines with more than two gigabytes of memory. The argument
1140 passed is the maximum amount of memory for the tests to use.

1149-------------
1150
Tim Petersb06d28c2006-05-12 01:57:59 +00001151- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1152
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001153- PEP 343: Added Context Types section to the library reference
1154 and attempted to bring other PEP 343 related documentation into
1155 line with the implementation and/or python-dev discussions.
1156
Tim Peters8dc73d22006-04-24 02:03:16 +00001157- Bug #1337990: clarified that ``doctest`` does not support examples
1158 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001161What's New in Python 2.5 alpha 1?
1162=================================
1163
Anthony Baxterebed3f62006-04-03 15:03:44 +00001164*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001165
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001166Core and builtins
1167-----------------
1168
Nick Coghlan43832302006-04-23 17:04:07 +00001169- PEP 338: -m command line switch now delegates to runpy.run_module
1170 allowing it to support modules in packages and zipfiles
1171
Martin v. Löwisc661b882006-04-20 04:54:23 +00001172- On Windows, .DLL is not an accepted file name extension for
1173 extension modules anymore; extensions are only found if they
1174 end in .PYD.
1175
Martin v. Löwisea62d252006-04-03 10:56:49 +00001176- Bug #1421664: sys.stderr.encoding is now set to the same value as
1177 sys.stdout.encoding.
1178
Neal Norwitz92e212f2006-04-03 04:48:37 +00001179- __import__ accepts keyword arguments.
1180
Georg Brandlccadf842006-03-31 18:54:53 +00001181- Patch #1460496: round() now accepts keyword arguments.
1182
Anthony Baxter262c00a2006-03-30 10:53:17 +00001183- Fixed bug #1459029 - unicode reprs were double-escaped.
1184
Hye-Shik Changd478f342006-03-23 12:32:36 +00001185- Patch #1396919: The system scope threads are reenabled on FreeBSD
1186 5.4 and later versions.
1187
Neal Norwitze98ccf62006-03-23 05:39:47 +00001188- Bug #1115379: Compiling a Unicode string with an encoding declaration
1189 now gives a SyntaxError.
1190
Georg Brandlabd1ff82006-03-18 07:59:59 +00001191- Previously, Python code had no easy way to access the contents of a
1192 cell object. Now, a ``cell_contents`` attribute has been added
1193 (closes patch #1170323).
1194
Tim Peterscf79aac2006-03-16 01:14:46 +00001195- Patch #1123430: Python's small-object allocator now returns an arena to
1196 the system ``free()`` when all memory within an arena becomes unused
1197 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1198 freed. Some applications will see a drop in virtual memory size now,
1199 especially long-running applications that, from time to time, temporarily
1200 use a large number of small objects. Note that when Python returns an
1201 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001202 platform C library will in turn return that memory to the operating system.
1203 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001204 appears to be effective at least on Microsoft C and gcc-based systems.
1205 Thanks to Evan Jones for hard work and patience.
1206
Georg Brandl533ff6f2006-03-08 18:09:27 +00001207- Patch #1434038: property() now uses the getter's docstring if there is
1208 no "doc" argument given. This makes it possible to legitimately use
1209 property() as a decorator to produce a read-only property.
1210
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001211- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1212 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1213 of requiring an int or long in slicing and a few other contexts, enabling
1214 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1215
Neal Norwitz995acdf2006-03-07 05:01:00 +00001216- Fixed various bugs reported by Coverity's Prevent tool.
1217
Brett Cannonbf364092006-03-01 04:25:17 +00001218- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1219 new exception base class, BaseException, which has a new message attribute.
1220 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1221 Raising a string exception now raises a DeprecationWarning.
1222
Thomas Woutersfb609f42006-02-28 16:37:25 +00001223- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1224 explicitly relative, using 'from .module import name' to mean 'from the same
1225 package as this module is in. Imports without dots still default to the
1226 old relative-then-absolute, unless 'from __future__ import
1227 absolute_import' is used.
1228
Brett Cannona7446e32006-02-27 23:39:10 +00001229- Properly check if 'warnings' raises an exception (usually when a filter set
1230 to "error" is triggered) when raising a warning for raising string
1231 exceptions.
1232
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001233- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001234 The name was removed from Include/code.h.
1235
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001236- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001237
Guido van Rossum1968ad32006-02-25 22:38:04 +00001238- Patch 1433928:
1239 - The copy module now "copies" function objects (as atomic objects).
1240 - dict.__getitem__ now looks for a __missing__ hook before raising
1241 KeyError.
1242
Tim Peters84ef21c2006-02-28 20:39:06 +00001243- PEP 343: with statement implemented. Needs ``from __future__ import
1244 with_statement``. Use of 'with' as a variable will generate a warning.
1245 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001246 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001247 The following objects have __context__ methods:
1248 - The built-in file type.
1249 - The thread.LockType type.
1250 - The following types defined by the threading module:
1251 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1252 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001253
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001254- Fix the encodings package codec search function to only search
1255 inside its own package. Fixes problem reported in patch #1433198.
1256
1257 Note: Codec packages should implement and register their own
1258 codec search function. PEP 100 has the details.
1259
Tim Peters9ea89d22006-06-04 03:26:02 +00001260- PEP 353: Using ``Py_ssize_t`` as the index type.
1261
1262- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1263 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1264 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1265 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1266 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001267
Neal Norwitzfc76d632006-01-10 06:03:13 +00001268- Patch #1400181, fix unicode string formatting to not use the locale.
1269 This is how string objects work. u'%f' could use , instead of .
1270 for the decimal point. Now both strings and unicode always use periods.
1271
Neal Norwitz671b9e32006-01-09 07:07:12 +00001272- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1273 configure would break checking curses.h.
1274
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001275- Bug #959576: The pwd module is now builtin. This allows Python to be
1276 built on UNIX platforms without $HOME set.
1277
Neal Norwitzc10978f2005-12-19 06:07:16 +00001278- Bug #1072182, fix some potential problems if characters are signed.
1279
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001280- Bug #889500, fix line number on SyntaxWarning for global declarations.
1281
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001282- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1283
Neal Norwitze7214a12005-12-18 05:03:17 +00001284- Support for converting hex strings to floats no longer works.
1285 This was not portable. float('0x3') now raises a ValueError.
1286
Barry Warsaw2a38a862005-12-18 01:27:35 +00001287- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001288 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001289 is now displayed in interactive prompt banner.
1290
Georg Brandlfa166682005-12-17 21:45:17 +00001291- Implementation of PEP 341 - Unification of try/except and try/finally.
1292 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001293 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001294
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001295- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1296 now encodes backslash correctly.
1297
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001298- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1299
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001300- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001301 and long longs.
1302
Neal Norwitz67715f02005-11-09 06:59:35 +00001303- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001304 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001305 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001306
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001307- Replaced most Unicode charmap codecs with new ones using the
1308 new Unicode translate string feature in the builtin charmap
1309 codec; the codecs were created from the mapping tables available
1310 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1311 encodings now include a mapping for the Apple logo)
1312
Tim Peterse3547fd2005-12-16 23:13:57 +00001313- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001314
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001315- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001316
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001317- A new AST parser implementation was completed. The abstract
1318 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001319 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001320
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001321- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001322 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1323
Neal Norwitz708e51a2005-10-03 04:48:15 +00001324- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1325
Neal Norwitz11bd1192005-10-03 00:54:56 +00001326- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1327 Provide a warning when a directory is passed on the command line.
1328
Neal Norwitz40d37812005-10-02 01:48:49 +00001329- Fix segfault with invalid coding.
1330
1331- SF bug #772896: unknown encoding results in MemoryError.
1332
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001333- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001334 supported a __len__() method which evaluated to False when the iterator
1335 was empty.
1336
Guido van Rossum630db602005-09-20 18:49:54 +00001337- On 64-bit platforms, when __len__() returns a value that cannot be
1338 represented as a C int, raise OverflowError.
1339
Skip Montanarof8948ca2005-09-19 03:54:46 +00001340- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001341 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001342
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001343- SF bug #893549: parsing keyword arguments was broken with a few format
1344 codes.
1345
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001346- Changes donated by Elemental Security to make it work on AIX 5.3
1347 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1348 bug #105470: test_pwd fails on 64bit system (Opteron).
1349
Guido van Rossum539c6622005-09-14 17:49:54 +00001350- Changes donated by Elemental Security to make it work on HP-UX 11 on
1351 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1352
Georg Brandl4550b8d2005-08-26 06:43:52 +00001353- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001354 (fixes bug #1119418).
1355
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001356- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1357
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001358- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1359 exceptions that cause a function to exit.
1360
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001361- The implementation of set() and frozenset() was revised to use its
1362 own internal data structure. Memory consumption is reduced by 1/3
1363 and there are modest speed-ups as well. The API is unchanged.
1364
Tim Petersde7990b2005-07-17 23:45:23 +00001365- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1366
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001367- SF bug #1229429: PyObject_CallMethod failed to decrement some
1368 reference counts in some error exit cases.
1369
Tim Petersecc6e6a2005-07-10 22:30:55 +00001370- SF bug #1185883: Python's small-object memory allocator took over
1371 a block managed by the platform C library whenever a realloc specified
1372 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001373 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001374 portable way to copy data from the C-managed block into Python's
1375 small-object space without risking a memory fault. Python's small-object
1376 realloc now leaves such blocks under the control of the platform C
1377 realloc.
1378
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001379- SF bug #1232517: An overflow error was not detected properly when
1380 attempting to convert a large float to an int in os.utime().
1381
Raymond Hettinger3296e692005-06-29 23:29:56 +00001382- SF bug #1224347: hex longs now print with lowercase letters just
1383 like their int counterparts.
1384
Michael W. Hudson188d4362005-06-20 16:52:57 +00001385- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1386 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1387 interpreter states; back out that fix and do a better job (see
1388 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1389 for a longer write-up of the problem).
1390
Michael W. Hudsondf888462005-06-03 14:41:55 +00001391- SF patch #1180995: marshal now uses a binary format by default when
1392 serializing floats.
1393
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001394- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1395 the routines that promise to produce IEEE 754 binary representations
1396 of floats now simply copy bytes around.
1397
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001398- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1399 278.
1400
Brett Cannonc3647ac2005-04-26 03:45:26 +00001401- patch #1109424: int, long, float, complex, and unicode now check for the
1402 proper magic slot for type conversions when subclassed. Previously the
1403 magic slot was ignored during conversion. Semantics now match the way
1404 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001405 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001406 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001407 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001408
Barry Warsawc8d907c2005-04-19 23:43:40 +00001409- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1410 NULL, now raise an AttributeError when attempting to set or delete the
1411 attribute. Previously a TypeError was raised, but this was inconsistent
1412 with the equivalent pure-Python implementation.
1413
Michael W. Hudson774479c2005-04-18 08:46:17 +00001414- It is now safe to call PyGILState_Release() before
1415 PyEval_InitThreads() (note that if there is reason to believe there
1416 are multiple threads around you still must call PyEval_InitThreads()
1417 before using the Python API; this fix is for extension modules that
1418 have no way of knowing if Python is multi-threaded yet).
1419
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001420- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1421 disabled caused a crash.
1422
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001423- Bug #1165306: instancemethod_new allowed the creation of a method
1424 with im_class == im_self == NULL, which caused a crash when called.
1425
Tim Petersecc6e6a2005-07-10 22:30:55 +00001426- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001427 fixes the crash seen in bug #1165761
1428
Raymond Hettinger96229b12005-03-11 06:49:40 +00001429- Added two new builtins, any() and all().
1430
Brett Cannon409d8f22005-03-05 06:47:57 +00001431- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001432 (e.g., ``class C(): pass`` is no longer a syntax error).
1433 Patch #1176012 added support to the 'parser' module and 'compiler' package
1434 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001435
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001436- Patch #1115086: Support PY_LONGLONG in structmember.
1437
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001438- Bug #1155938: new style classes did not check that __init__() was
1439 returning None.
1440
Tim Petersecc6e6a2005-07-10 22:30:55 +00001441- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001442 ('\') with a specific error message.
1443
Martin v. Löwisff232d72005-03-03 09:24:38 +00001444- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1445
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001446- Bug #1124295: the __name__ attribute of file objects was
1447 inadvertently made inaccessible in restricted mode.
1448
Tim Petersecc6e6a2005-07-10 22:30:55 +00001449- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001450 an ferror() call.
1451
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001452- min() and max() now support key= arguments with the same meaning as in
1453 list.sort().
1454
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001455- The peephole optimizer now performs simple constant folding in expressions:
1456 (2+3) --> (5).
1457
Raymond Hettingera422c342005-01-11 03:03:27 +00001458- set and frozenset objects can now be marshalled. SF #1098985.
1459
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001460- Bug #1077106: Poor argument checking could cause memory corruption
1461 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001462
Jeremy Hyltonab630502005-02-04 18:44:06 +00001463- The parser did not complain about future statements in illegal
1464 positions. It once again reports a syntax error if a future
1465 statement occurs after anything other than a doc string.
1466
Neil Schemenauercf52c072005-08-12 17:34:58 +00001467- Change the %s format specifier for str objects so that it returns a
1468 unicode instance if the argument is not an instance of basestring and
1469 calling __str__ on the argument returns a unicode instance.
1470
Tim Petersf4e69282006-02-27 17:15:31 +00001471- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1472 current thread state when the auto-GIL-state machinery knows about
1473 it (since the thread state is being deleted, continuing to remember it
1474 can't help, but can hurt if another thread happens to get created with
1475 the same thread id).
1476
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001477Extension Modules
1478-----------------
1479
Georg Brandl43f08a82006-03-31 18:01:16 +00001480- Patch #1380952: fix SSL objects timing out on consecutive read()s
1481
Neal Norwitz05a45592006-03-20 06:30:08 +00001482- Patch #1309579: wait3 and wait4 were added to the posix module.
1483
Anthony Baxterfa869072006-03-20 05:21:58 +00001484- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1485 In addition, the existing ulaw code was updated.
1486
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001487- RFE #567972: Socket objects' family, type and proto properties are

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001670
Nick Coghlan43832302006-04-23 17:04:07 +00001671- PEP 338: new module runpy defines a run_module function to support
1672 executing modules which provide access to source code or a code object
1673 via the PEP 302 import mechanisms.
1674
Anthony Baxter93f5b932006-04-03 08:05:07 +00001675- The email module's parsedate_tz function now sets the daylight savings

1683 in attribute values.
1684
Anthony Baxterc51ee692006-04-01 00:57:31 +00001685- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001686 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001687 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001688 module will not be built.
1689
Tim Petersc17976e2006-04-01 00:26:53 +00001690- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1691 aren't officially supported here, and trying to use them will probably
1692 raise an exception some day. But dicts have been allowed, and "mostly
1693 worked", so support for them won't go away without warning.
1694
Georg Brandl338ef7d2006-03-31 18:42:16 +00001695- Bug #1445068: getpass.getpass() can now be given an explicit stream
1696 argument to specify where to write the prompt.
1697

1713
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001714- email 4.0 package now integrated. This is largely the same as the email 3.0
1715 package that was included in Python 2.3, except that PEP 8 module names are
1716 now used (e.g. mail.message instead of email.Message). The MIME classes
1717 have been moved to a subpackage (e.g. email.mime.text instead of
1718 email.MIMEText). The old names are still supported for now. Several
1719 deprecated Message methods have been removed and lots of bugs have been
1720 fixed. More details can be found in the email package documentation.
1721
Walter Dörwald40108c92006-03-27 08:15:44 +00001722- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1723 (a subclass of tuple) that provides incremental decoders and encoders
1724 (a way to use stateful codecs without the stream API). Python functions
1725 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1726 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1727 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001729- Patch #1359365: Calling next() on a closed StringIO.String object raises
1730 a ValueError instead of a StopIteration now (like file and cString.String do).
1731 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1732 called before (like file and StringIO.StringIO do).

1808 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1809 Ronald L. Rivest offered this advice for Python:
1810
1811 "The consensus of researchers in this area (at least as
1812 expressed at the NIST Hash Function Workshop 10/31/05),
1813 is that SHA-256 is a good choice for the time being, but
1814 that research should continue, and other alternatives may
1815 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001816

1997 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001998 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001999 PEP 305.

2002 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2003 dictates.
2004 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002005 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002006 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002007 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields

Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002009 + reader now allows \r characters to be quoted (previously it only allowed
2010 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002011 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002012 + Dialect classes passed to the module are no longer instantiated by
2013 the module before being parsed (the former validation scheme required
2014 this, but the mechanism was unreliable).
2015 + The dialect registry now contains instances of the internal
2016 C-coded dialect type, rather than references to python objects.
2017 + the internal c-coded dialect type is now immutable.
2018 + register_dialect now accepts the same keyword dialect specifications
2019 as the reader and writer, allowing the user to register dialects
2020 without first creating a dialect class.
2021 + a configurable limit to the size of parsed fields has been added -
2022 previously, an unmatched quote character could result in the entire
2023 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002024 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002025 the parser field size limit (returning the former limit). The initial
2026 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002027 + A line_num attribute has been added to the reader object, which tracks
2028 the number of lines read from the source iterator. This is not
2029 the same as the number of records returned, as records can span
2030 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002031 + reader and writer objects were not being registered with the cyclic-GC.
2032 This has been fixed.
2033
Brett Cannone6539c42005-01-08 02:43:53 +00002034- _DummyThread objects in the threading module now delete self.__block that is
2035 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2036 lock primitives tend to be limited in number and thus should not be wasted on
2037 a _DummyThread object. Fixes bug #1089632.
2038
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002039- The imghdr module now detects Exif files.
2040
Raymond Hettinger6065d322004-12-20 23:51:53 +00002041- StringIO.truncate() now correctly adjusts the size attribute.
2042 (Bug #951915).
2043
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002044- locale.py now uses an updated locale alias table (built using
2045 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2046 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002047 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002048
Raymond Hettinger3557f422004-12-07 12:02:02 +00002049- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2050
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002051- the pickle module no longer accepts the deprecated None option in the
2052 args tuple returned by __reduce__().
2053
Brett Cannon84667c02004-12-07 03:25:18 +00002054- optparse now optionally imports gettext. This allows its use in setup.py.
2055
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002056- the pickle module no longer uses the deprecated bin parameter.
2057
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002058- the shelve module no longer uses the deprecated binary parameter.
2059
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002060- the pstats module no longer uses the deprecated ignore() method.
2061
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002062- the filecmp module no longer uses the deprecated use_statcache argument.
2063
Raymond Hettinger664347b2004-12-04 21:21:53 +00002064- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2065 extended or overridden by subclasses. Formerly, the subclassed method would
2066 be ignored by the rest of the module. (Bug #1078905).
2067
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002068- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002069 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002070
Walter Dörwald36733692004-12-22 12:50:50 +00002071- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2072 once when a size argument is given. This prevents a buffer overflow in the
2073 tokenizer with very long source lines.
2074
Barry Warsaw538561e2006-01-01 21:48:54 +00002075- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2076 immediately after creating the object, without any intervening
2077 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002078
Skip Montanaro05885812005-01-16 20:48:27 +00002079- The reconvert.quote function can now emit triple-quoted strings. The
2080 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002081
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002082- ``UserString.MutableString`` now supports negative indices in
2083 ``__setitem__`` and ``__delitem__``
2084
Greg Ward40407942005-03-05 02:53:17 +00002085- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2086 correctly.
2087
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002088- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2089 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2090 character even if the user has passed a size parameter to get a proper
2091 line ending. Remove the special handling of a "\r\n" that has been split
2092 between two lines.
2093
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002094- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2095 about illegal code points. The codec now supports PEP 293 style error
2096 handlers.
2097
Walter Dörwald78a78b02005-09-01 12:04:29 +00002098- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002099 from the input stream, so that the output is a byte string in the correct
2100 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002101
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002102- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2103 considering it exactly like a '*'.
2104
Walter Dörwald007f8df2005-10-09 19:42:27 +00002105- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2106 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002107
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002108- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2109
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002110- Patch #1413711: Certain patterns of differences were making difflib
2111 touch the recursion limit.
2112
Walter Dörwald58917a62006-03-31 15:26:22 +00002113- Bug #947906: An object oriented interface has been added to the calendar
2114 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002115 called as a script (e.g. via ``python -mcalendar``). Localized month and
2116 weekday names can be ouput (even if an exotic encoding is used) using
2117 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002118
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002119Build
2120-----
2121
Neal Norwitz602d3392006-03-31 08:21:40 +00002122- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2123 by using -mieee gcc option.
2124
Martin v. Löwis86d66262006-02-17 08:40:11 +00002125- Patch #1432345: Make python compile on DragonFly.
2126
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002127- Build support for Win64-AMD64 was added.
2128
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002129- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2130
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002131- Patch #881820: look for openpty and forkpty also in libbsd.
2132
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002133- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2134 The zlib module is now builtin on Windows.
2135
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002136- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2137
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002138- Bug #1189330: configure did not correctly determine the necessary
2139 value of LINKCC if python was built with GCC 4.0.
2140
Trent Mick8321b422005-07-26 02:29:21 +00002141- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2142 vulnerability in zlib 1.2.1 and 1.2.2.
2143
Brett Cannon08cd5982005-04-24 22:26:38 +00002144- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2145 flags that change binary compatibility. Changes were also made to
2146 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002147 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002148
Bob Ippolitoed233462005-03-29 13:47:59 +00002149- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2150 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2151 no longer exists). This configure patch makes things right.
2152
Martin v. Löwise2713be2005-03-08 15:03:08 +00002153- Bug #1158607: Build with --disable-unicode again.
2154
Brett Cannon46d96232005-02-16 00:07:19 +00002155- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2156 defined. Discovered as a result of not being able to build on OS X.
2157
Brett Cannon516592f2004-12-07 00:42:59 +00002158- setup.py now uses the directories specified in LDFLAGS using the -L option
2159 and in CPPFLAGS using the -I option for adding library and include
2160 directories, respectively, for compiling extension modules against. This has
2161 led to the core being compiled using the values in CPPFLAGS. It also removes
2162 the need for the special-casing of both DarwinPorts and Fink for darwin since
2163 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2164 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2165 Fink, ``-I/opt/local/include`` for DarwinPorts).
2166
Brett Cannon43802422005-02-10 20:48:03 +00002167- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2168 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2169 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2170 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002172C API
2173-----
2174
Tim Petersc9d78aa2006-03-26 23:27:58 +00002175- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2176 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2177 is obtained via the ``PyObject_`` family, it must be released via the
2178 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2179 always been officially true, but when Python's small-object allocator was
2180 introduced, an attempt was made to cater to a few extension modules
2181 discovered at the time that obtained memory via ``PyObject_New`` but
2182 released it via ``PyMem_DEL``. It's years later, and if such code still
2183 exists it will fail now (probably with segfaults, but calling wrong
2184 low-level memory management functions can yield many symptoms).
2185
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002186- Added a C API for set and frozenset objects.
2187
Raymond Hettinger66517482004-12-03 11:45:13 +00002188- Removed PyRange_New().
2189
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002190- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2191 mapping argument now. This string is used as a mapping table. Byte values
2192 greater than the length of the string and 0xFFFE are treated as undefined
2193 mappings.
