20-----------------
21
Neal Norwitz0bcafac2006-09-11 08:51:17 +000022- Make _PyGILState_NoteThreadState() static, it was not used anywhere
23 outside of pystate.c and should not be necessary.
24
Brett Cannon19d76c52006-09-09 07:18:44 +000025- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
26 allows calling unicode() on exceptions classes directly to succeed.
27
Georg Brandlecab6232006-09-06 06:47:02 +000028- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
29 Also make sure that every exception class has __module__ set to
30 'exceptions'.
31
Georg Brandl37a9e572006-09-06 06:09:34 +000032- Bug #1550983: emit better error messages for erroneous relative
33 imports (if not in package and if beyond toplevel package).
34
Tim Peterscbdd3502006-09-05 01:47:53 +000035- Overflow checking code in integer division ran afoul of new gcc
36 optimizations. Changed to be more standard-conforming.
37
Neal Norwitz19c35bb2006-08-21 22:13:11 +000038- Patch #1541585: fix buffer overrun when performing repr() on
39 a unicode string in a build with wide unicode (UCS-4) support.
40
Neal Norwitzd3da7d32006-09-05 01:54:06 +000041- Patch #1546288: fix seg fault in dict_equal due to ref counting bug.
42
Neal Norwitz29a5fdb2006-09-05 02:21:38 +000043- The return tuple from str.rpartition(sep) is (tail, sep, head) where
44 head is the original string if sep was not found.
45
Neal Norwitz3b3aae02006-09-05 03:56:01 +000046- Bug #1520864: unpacking singleton tuples in list comprehensions and
47 generator expressions (x for x, in ... ) works again. Fixing this problem
48 required changing the .pyc magic number. This means that .pyc files
49 generated before 2.5c2 will be regenerated.

Guido van Rossumc69ac252006-08-10 18:09:25 +0000133What's New in Python 2.5 release candidate 1?

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000137
138Core and builtins
139-----------------
140
Neal Norwitz24b6f202006-09-05 04:43:56 +0000141- Fix infinite recursion when subclassing long and overriding __hash__.
142
143- Fix concatenation (+=) of long strings.
144
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000145- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000146 compared equal or unequal to a string and a UnicodeDecodeError
147 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000148
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000149 Instead, the equal (==) and unequal (!=) comparison operators will
150 now issue a UnicodeWarning and interpret the two objects as
151 unequal. The UnicodeWarning can be filtered as desired using
152 the warning framework, e.g. silenced completely, turned into an
153 exception, logged, etc.
154
155 Note that compare operators other than equal and unequal will still
156 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000157
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000158- Fix segfault when doing string formatting on subclasses of long.
159
160- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
161 with new-style classes.
162
163- Fix bug related to __len__ functions returning negative values with
164 classic classes.
165
166- Patch #1538606, Fix __index__() clipping. There were some problems
167 discovered with the API and how integers that didn't fit into Py_ssize_t
168 were handled. This patch attempts to provide enough alternatives
169 to effectively use __index__.
170
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000171- Bug #1536021: __hash__ may now return long int; the final hash
172 value is obtained by invoking hash on the long int.
173
Thomas Hellerab1049c2006-08-08 17:37:00 +0000174- Bug #1536786: buffer comparison could emit a RuntimeWarning.
175
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000176- Bug #1535165: fixed a segfault in input() and raw_input() when
177 sys.stdin is closed.
178
Thomas Heller74d36f02006-08-04 18:17:40 +0000179- On Windows, the PyErr_Warn function is now exported from
180 the Python dll again.
181
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000182- Bug #1191458: tracing over for loops now produces a line event
183 on each iteration. Fixing this problem required changing the .pyc
184 magic number. This means that .pyc files generated before 2.5c1
185 will be regenerated.
186
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000187- Bug #1333982: string/number constants were inappropriately stored
188 in the byte code and co_consts even if they were not used, ie
189 immediately popped off the stack.
190
Georg Brandle9462c72006-08-04 18:03:37 +0000191- Fixed a reference-counting problem in property().

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000193
194Library
195-------
196
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000197- Fix a bug in the ``compiler`` package that caused invalid code to be
198 generated for generator expressions.
199
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000200- The distutils version has been changed to 2.5.0. The change to
201 keep it programmatically in sync with the Python version running
202 the code (introduced in 2.5b3) has been reverted. It will continue
203 to be maintained manually as static string literal.
204
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000205- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000206 and this cannot be converted to the required C type, an exception is
207 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000208 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000209
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000210- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000211 an exception.
212
Tim Peterscbdd3502006-09-05 01:47:53 +0000213- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000214 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000215 workarounds for clocks with low resolution, to stop the code yielding
216 duplicate UUIDs.
217
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000218- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
219 before raising SystemExit, allowing IDLE to honor quit() and exit().
220
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000221- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
222
Georg Brandl7a1af772006-08-14 21:55:28 +0000223- Patch #1536071: trace.py should now find the full module name of a
224 file correctly even on Windows.
225
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000226- logging's atexit hook now runs even if the rest of the module has
227 already been cleaned up.
228
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000229- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000230
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000231- Bug #1531405, format_exception no longer raises an exception if
232 str(exception) raised an exception.
233
Neil Schemenauer06ded092006-08-04 16:20:30 +0000234- Fix a bug in the ``compiler`` package that caused invalid code to be
235 generated for nested functions.

246 raises the correct exceptions.
247
Thomas Heller1ce433e2006-08-14 16:20:04 +0000248- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
249 '-no-stack-protector' compiler flag for OpenBSD has been removed.
250
Thomas Heller86720042006-08-14 11:17:48 +0000251- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
252 uses the _as_parameter_ attribute when objects are passed to foreign
253 function calls. The ctypes version number was changed to 1.0.1.
254
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000255- Bug #1530559, struct.pack raises TypeError where it used to convert.
256 Passing float arguments to struct.pack when integers are expected
257 now triggers a DeprecationWarning.
258
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000259

309
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000310- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000311 returned a long (see PEP 353).
312
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000313- Bug #1515471: string.replace() accepts character buffers again.

Neal Norwitz07aadb12006-07-30 06:55:48 +0000315- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
316 This provides the proper warning for struct.pack().
317 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().

Neal Norwitz0d62a062006-07-30 06:53:31 +0000319- Patch #1531113: Fix augmented assignment with yield expressions.
320 Also fix a SystemError when trying to assign to yield expressions.
321
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000322- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
323 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
324 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
325 excessive filesystem operations during imports.
326
Tim Petersbc24eee2006-07-27 01:14:53 +0000327- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
328 operations on signed longs that are formally undefined by C.
329 Unfortunately, at least one compiler now cares about that, so complicated
330 the code to make that compiler happy again.
331
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000332- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
333
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000334- Patch #1232023: Stop including current directory in search
335 path on Windows.
336
Neal Norwitze1fdb322006-07-21 05:32:28 +0000337- Fix some potential crashes found with failmalloc.
338
Neal Norwitze7563102006-07-17 01:00:16 +0000339- Fix warnings reported by Klocwork's static analysis tool.
340
Neal Norwitz84be93b2006-07-16 01:50:38 +0000341- Bug #1512814, Fix incorrect lineno's when code within a function
342 had more than 255 blank lines.
343
Georg Brandl9dceedb2006-07-12 15:31:17 +0000344- Patch #1521179: Python now accepts the standard options ``--help`` and
345 ``--version`` as well as ``/?`` on Windows.
346
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000347- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000348 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000349 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000350
Tim Peters112aad32006-07-19 00:03:19 +0000351- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000352 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000353 new ``sys._current_frames()`` returns a dictionary with one entry,
354 mapping the faux "thread id" 0 to the current frame.

Ronald Oussoren3075e162006-07-25 20:28:55 +0000356- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

360-------
361
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000362- Correction of patch #1455898: In the mbcs decoder, set final=False
363 for stream decoder, but final=True for the decode function.
364
Georg Brandl07fec3a2006-08-01 18:49:24 +0000365- os.urandom no longer masks unrelated exceptions like SystemExit or
366 KeyboardInterrupt.
367
Tim Peters4643c2f2006-08-10 22:45:34 +0000368- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000369 shutil.copytree on Windows
370
Georg Brandle34ac7c2006-07-30 11:07:23 +0000371- Bug #1002398: The documentation for os.path.sameopenfile now correctly
372 refers to file descriptors, not file objects.
373
Tim Peterscbdd3502006-09-05 01:47:53 +0000374- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000375 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000376 #1513611, and probably others.
377
Georg Brandledd9b0d2006-07-29 09:33:26 +0000378- Bug #1441397: The compiler module now recognizes module and function
379 docstrings correctly as it did in Python 2.4.
380
Tim Peters6f681472006-07-27 23:44:37 +0000381- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
382 lost that tests are sorted by name before being run. This rarely
383 matters for well-written tests, but can create baffling symptoms if
384 side effects from one test to the next affect outcomes. ``DocTestFinder``
385 has been changed to sort the list of tests it returns.
386
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000387- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000388 in sync with sys.version_info[:3].

Georg Brandlcf0c1722006-07-26 07:23:32 +0000395- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
396 to recursive calls and call it with the failing package name.
397
Martin v. Löwis0b483032006-07-25 09:53:12 +0000398- Bug #1525817: Don't truncate short lines in IDLE's tool tips.

Georg Brandlc13c34c2006-07-24 14:09:56 +0000400- Patch #1515343: Fix printing of deprecated string exceptions with a
401 value in the traceback module.
402
Greg Ward48fae7a2006-07-23 16:05:51 +0000403- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
404
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000405- Patch #1524429: Use repr() instead of backticks in Tkinter again.
406
Brett Cannoncaebe222006-07-18 04:41:36 +0000407- Bug #1520914: Change time.strftime() to accept a zero for any position in its
408 argument tuple. For arguments where zero is illegal, the value is forced to
409 the minimum value that is correct. This is to support an undocumented but
410 common way people used to fill in inconsequential information in the time
411 tuple pre-2.4.
412
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000413- Patch #1220874: Update the binhex module for Mach-O.
414
Barry Warsawb110bad2006-07-21 14:51:07 +0000415- The email package has improved RFC 2231 support, specifically for
416 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
417 (name*0=<blah>) parameter continuations. This may change the types of
418 values returned from email.message.Message.get_param() and friends.
419 Specifically in some cases where non-encoded continuations were used,
420 get_param() used to return a 3-tuple of (None, None, string) whereas now it
421 will just return the string (since non-encoded continuations don't have
422 charset and language parts).
423
424 Also, whereas % values were decoded in all parameter continuations, they are
425 now only decoded in encoded parameter parts.
426
Ronald Oussoren3075e162006-07-25 20:28:55 +0000427- Bug #1517990: IDLE keybindings on MacOS X now work correctly
428
429- Bug #1517996: IDLE now longer shows the default Tk menu when a
430 path browser, class browser or debugger is the frontmost window on MacOS X
431
Barry Warsaw00decd72006-07-27 23:43:15 +0000432- Patch #1520294: Support for getset and member descriptors in types.py,
433 inspect.py, and pydoc.py. Specifically, this allows for querying the type
434 of an object against these built-in types and more importantly, for getting
435 their docstrings printed in the interactive interpreter's help() function.

440
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000441- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
442 a socket operation on a socket with a timeout, the exception will be
443 caught correctly. Previously, the exception was not caught.
444
Thomas Heller1393d6a2006-07-28 21:43:20 +0000445- Patch #1529514: The _ctypes extension is now compiled on more
446 openbsd target platforms.
447
Tim Peters9cab5932006-07-28 00:30:00 +0000448- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
449 a memory leak, affecting pickles and deep copies.
450
Tim Petersbc24eee2006-07-27 01:14:53 +0000451- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

453
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000454- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
455
Thomas Hellerce049a02006-07-14 17:51:14 +0000456- Patch #1521817: Index range checking on ctypes arrays containing
457 exactly one element enabled again. This allows iterating over these
458 arrays, without the need to check the array size before.
459
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000460- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000461 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000462 /dev/null in certain cases; this is now fixed.
463
Thomas Heller47d7a062006-07-12 08:43:47 +0000464- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
465 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000466
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000467- Because of a misspelled preprocessor symbol, ctypes was always
468 compiled without thread support; this is now fixed.
469
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000470- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
471 methods now allow their database parameter to be None as the
472 sleepycat API allows.
473
Matt Flemingec926502006-07-28 11:27:27 +0000474- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
475 bluetooth API compared with Linux and FreeBSD.
476

478-----
479
480- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
481 how long the test file should take to play. Now accepts taking 2.93 secs
482 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
483
Georg Brandl4793aa32006-07-28 18:31:39 +0000484- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
485 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
486 run via ``regrtest.py``. Now they do.

495
496- PythonLauncher now works correctly when the path to the script contains
497 characters that are treated specially by the shell (such as quotes).
498
499- Bug #1527397: PythonLauncher now launches scripts with the working directory
500 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000501 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000502 expect.

512
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000513- Bug #1441486: The literal representation of -(sys.maxint - 1)
514 again evaluates to a int object, not a long.
515
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000516- Bug #1501934: The scope of global variables that are locally assigned
517 using augmented assignment is now correctly determined.
518
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000519- Bug #927248: Recursive method-wrapper objects can now safely
520 be released.
521
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000522- Bug #1417699: Reject locale-specific decimal point in float()
523 and atof().
524
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000525- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
526 omit a default "error" argument for NULL pointer. This allows
527 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000528
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000529- Bug #1519018: 'as' is now validated properly in import statements.
530
Neal Norwitz28746ab2006-07-09 22:14:42 +0000531- On 64 bit systems, int literals that use less than 64 bits are
532 now ints rather than longs.
533
Neal Norwitzed657552006-07-10 00:04:44 +0000534- Bug #1512814, Fix incorrect lineno's when code at module scope
535 started after line 256.
536
Tim Peters32a83612006-07-10 21:08:24 +0000537- New function ``sys._current_frames()`` returns a dict mapping thread
538 id to topmost thread stack frame. This is for expert use, and is
539 especially useful for debugging application deadlocks. The functionality
540 was previously available in Fazal Majid's ``threadframe`` extension
541 module, but it wasn't possible to do this in a wholly threadsafe way from
542 an extension.

551
Tim Peters32a83612006-07-10 21:08:24 +0000552- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000553 environment variable to be set in order to the SDK environment
554 for finding the compiler, include files, etc.

Nick Coghlan2d792252006-07-06 13:47:18 +0000558- warnings.py now ignores ImportWarning by default
559
Thomas Woutersadd19112006-07-05 11:03:49 +0000560- string.Template() now correctly handles tuple-values. Previously,
561 multi-value tuples would raise an exception and single-value tuples would
562 be treated as the value they contain, instead.
563
Martin v. Löwisede77f52006-07-03 13:01:35 +0000564- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
565 even if some data are received.
566
Martin v. Löwis45482392006-07-03 12:28:58 +0000567- Bug #1267547: Put proper recursive setup.py call into the

571 degrees and radians.
572
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000573- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000574 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000575
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000576- Bug #1514703: Only setup canvas window in turtle when the canvas
577 is created.
578
Martin v. Löwis7596e832006-07-01 15:33:37 +0000579- Bug #1513223: .close() of a _socketobj now releases the underlying
580 socket again, which then gets closed as it becomes unreferenced.
581
Fred Drake10497c82006-06-29 02:57:48 +0000582- Bug #1504333: Make sgmllib support angle brackets in quoted
583 attribute values.
584
585- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
586 sgmllib ('[' and ']' were not accepted).
587
Georg Brandl1be63af2006-06-28 20:23:25 +0000588- Fix a bug in the turtle module's end_fill function.
589
Brett Cannon53ab5b72006-06-22 16:49:14 +0000590- Bug #1510580: The 'warnings' module improperly required that a Warning
591 category be either a types.ClassType and a subclass of Warning. The proper
592 check is just that it is a subclass with Warning as the documentation states.
593
Georg Brandlad29e632006-06-21 17:45:17 +0000594- The compiler module now correctly compiles the new try-except-finally
595 statement (bug #1509132).
596
Neal Norwitz60373cd2006-06-22 06:30:50 +0000597- The wsgiref package is now installed properly on Unix.
598
Vinay Sajip28e57612006-07-01 10:45:20 +0000599- A bug was fixed in logging.config.fileConfig() which caused a crash on
600 shutdown when fileConfig() was called multiple times.
601
Gerhard Häring762fbd32006-07-02 17:48:30 +0000602- The sqlite3 module did cut off data from the SQLite database at the first
603 null character before sending it to a custom converter. This has been fixed
604 now.

Tim Peters112aad32006-07-19 00:03:19 +0000609- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
610 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
611 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000612
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000613- Assigning None to pointer type fields in ctypes structures possible
614 overwrote the wrong fields, this is fixed now.
615
616- Fixed a segfault in _ctypes when ctypes.wintypes were imported
617 on non-Windows platforms.
618
619- Bug #1518190: The ctypes.c_void_p constructor now accepts any
620 integer or long, without range checking.
621
622- Patch #1517790: It is now possible to use custom objects in the ctypes
623 foreign function argtypes sequence as long as they provide a from_param
624 method, no longer is it required that the object is a ctypes type.
625
626- The '_ctypes' extension module now works when Python is configured
627 with the --without-threads option.
628
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000629- Bug #1513646: os.access on Windows now correctly determines write
630 access, again.
631
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000632- Bug #1512695: cPickle.loads could crash if it was interrupted with
633 a KeyboardInterrupt.
634
Neal Norwitza12aa882006-07-06 06:45:08 +0000635- Bug #1296433: parsing XML with a non-default encoding and
636 a CharacterDataHandler could crash the interpreter in pyexpat.
637
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000638- Patch #1516912: improve Modules support for OpenVMS.

641-----
642
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000643- Automate Windows build process for the Win64 SSL module.
644
Tim Peters32a83612006-07-10 21:08:24 +0000645- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000646 Previously, the slight difference could cause compilation errors of the
647 'zlib' module on systems with more than one version of zlib.
648
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000649- The MSI compileall step was fixed to also support a TARGETDIR
650 with spaces in it.
651
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000652- Bug #1517388: sqlite3.dll is now installed on Windows independent
653 of Tcl/Tk.
654
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000655- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000656 trying to be installed even though it's empty.

659-----
660
661- Call os.waitpid() at the end of tests that spawn child processes in order
662 to minimize resources (zombies).
663
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000664Documentation
665-------------
666
Nick Coghlan2d792252006-07-06 13:47:18 +0000667- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
668 documentation for the warnings module.
669
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000670- Patch #1509163: MS Toolkit Compiler no longer available.
671
Neal Norwitz56640df2006-07-10 02:36:41 +0000672- Patch #1504046: Add documentation for xml.etree.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000677
Anthony Baxterd1136802006-06-19 12:04:15 +0000678*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000679
680Core and builtins
681-----------------
682
Georg Brandla56b9152006-06-19 06:35:54 +0000683- Patch #1507676: Error messages returned by invalid abstract object operations
684 (such as iterating over an integer) have been improved and now include the
685 type of the offending object to help with debugging.
686
Brett Cannonea3912b2006-06-13 21:46:41 +0000687- Bug #992017: A classic class that defined a __coerce__() method that returned
688 its arguments swapped would infinitely recurse and segfault the interpreter.
689
Neal Norwitz909eb122006-06-12 02:13:21 +0000690- Fix the socket tests so they can be run concurrently.
691
Neal Norwitzb9845e72006-06-12 02:11:18 +0000692- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000693 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000694
Brett Cannon22565aa2006-06-09 22:31:23 +0000695- Bug #532646: object.__call__() will continue looking for the __call__
696 attribute on objects until one without one is found. This leads to recursion
697 when you take a class and set its __call__ attribute to an instance of the
698 class. Originally fixed for classic classes, but this fix is for new-style.
699 Removes the infinite_rec_3 crasher.
700
Georg Brandl24250812006-06-09 18:45:48 +0000701- The string and unicode methods startswith() and endswith() now accept
702 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
703
Brett Cannonde3b0522006-06-08 17:00:45 +0000704- Buffer objects, at the C level, never used the char buffer
705 implementation even when the char buffer for the wrapped object was
706 explicitly requested (originally returned the read or write buffer).
707 Now a TypeError is raised if the char buffer is not present but is
708 requested.
709
Georg Brandlddbaa662006-06-04 21:56:52 +0000710- Patch #1346214: Statements like "if 0: suite" are now again optimized
711 away like they were in Python 2.4.
712
Georg Brandlb7c8f542006-05-27 12:30:25 +0000713- Builtin exceptions are now full-blown new-style classes instead of
714 instances pretending to be classes, which speeds up exception handling
715 by about 80% in comparison to 2.5a2.
716
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000717- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
718 Unicode 4.1.
719
Georg Brandlf4ef1162006-05-26 18:03:31 +0000720- Patch #921466: sys.path_importer_cache is now used to cache valid and
721 invalid file paths for the built-in import machinery which leads to
722 fewer open calls on startup.
723
Tim Peters696cf432006-05-24 21:10:40 +0000724- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
725 of-2 bases. The largest speedup is for inputs with about 1000 decimal
726 digits. Conversion from non-power-of-2 bases remains quadratic-time in
727 the number of input digits (it was and remains linear-time for bases
728 2, 4, 8, 16 and 32).
729
Tim Petersb713ec22006-05-23 18:45:30 +0000730- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
731 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
732 an integer close to ``sys.maxint``. This was repaired by patch
733 #1335972, which also gives a nice speedup.
734
Richard Jonescebbefc2006-05-23 18:28:17 +0000735- Patch #1337051: reduced size of frame objects.
736
737- PyErr_NewException now accepts a tuple of base classes as its
738 "base" parameter.
739
Richard Jones7c88dcc2006-05-23 10:37:38 +0000740- Patch #876206: function call speedup by retaining allocated frame
741 objects.
742
Georg Brandl7b90e162006-05-18 07:01:27 +0000743- Bug #1462152: file() now checks more thoroughly for invalid mode
744 strings and removes a possible "U" before passing the mode to the
745 C library function.
746
Neal Norwitz1004a532006-05-15 07:17:23 +0000747- Patch #1488312, Fix memory alignment problem on SPARC in unicode
748
Neal Norwitz373f0a72006-05-15 07:04:36 +0000749- Bug #1487966: Fix SystemError with conditional expression in assignment
750
Martin v. Löwis879768d2006-05-11 13:28:43 +0000751- WindowsError now has two error code attributes: errno, which carries
752 the error values from errno.h, and winerror, which carries the error
753 values from winerror.h. Previous versions put the winerror.h values
754 (from GetLastError()) into the errno attribute.
755
Martin v. Löwis77736712006-05-04 05:51:03 +0000756- Patch #1475845: Raise IndentationError for unexpected indent.
757
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000758- Patch #1479181: split open() and file() from being aliases for each other.
759
Tim Peters44bd9862006-06-01 13:49:23 +0000760- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
761 methods were always silently ignored by dictionaries when comparing keys.
762 They are now passed through (except when using the C API function
763 ``PyDict_GetItem()``, whose semantics did not change).
764
765- Bug #1456209: In some obscure cases it was possible for a class with a
766 custom ``__eq__()`` method to confuse dict internals when class instances
767 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
768 No, you don't have any code that did this ;-)

774
775- Patch #1462338: Upgrade pyexpat to expat 2.0.0
776
Brett Cannon6ee7d012006-06-08 16:23:04 +0000777- Change binascii.hexlify to accept a read-only buffer instead of only a char
778 buffer and actually follow its documentation.
779
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000780- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
781
Nick Coghlanc649ec52006-05-29 12:43:05 +0000782- Patch #1478788 (modified version): The functional extension module has
783 been renamed to _functools and a functools Python wrapper module added.
784 This provides a home for additional function related utilities that are
785 not specifically about functional programming. See PEP 309.
786
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000787- Patch #1493701: performance enhancements for struct module.
788
Georg Brandl378d5922006-05-17 14:26:50 +0000789- Patch #1490224: time.altzone is now set correctly on Cygwin.
790
Georg Brandl8d3342b2006-05-16 07:38:27 +0000791- Patch #1435422: zlib's compress and decompress objects now have a
792 copy() method.
793
Andrew MacIntyre92913322006-06-13 15:04:24 +0000794- Patch #1454481: thread stack size is now tunable at runtime for thread
795 enabled builds on Windows and systems with Posix threads support.
796
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000797- On Win32, os.listdir now supports arbitrarily-long Unicode path names
798 (up to the system limit of 32K characters).
799
800- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
801 As a result, these functions now raise WindowsError instead of OSError.
802
Tim Peters7a822da2006-05-25 21:50:17 +0000803- ``time.clock()`` on Win64 should use the high-performance Windows
804 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
805 Windows platforms).
806
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000807- Calling Tk_Init twice is refused if the first call failed as that
808 may deadlock.
809
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000810- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
811 accept it without potentially using an uninitialized pointer.
812
813- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
814 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
815 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000816
Gregory P. Smith372b5832006-06-05 18:48:21 +0000817- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000818 [pybsddb project SF patch number 1466734]
819
Gregory P. Smith372b5832006-06-05 18:48:21 +0000820- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
821 parameter is supplied. [SF pybsddb bug #1477863]
822
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000823- bsddb: the __len__ method of a DB object has been fixed to return correct
824 results. It could previously incorrectly return 0 in some cases.
825 Fixes SF bug 1493322 (pybsddb bug 1184012).
826
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000827- bsddb: the bsddb.dbtables Modify method now raises the proper error and
828 aborts the db transaction safely when a modifier callback fails.
829 Fixes SF python patch/bug #1408584.
830
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000831- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000832 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000833 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
834 database calls that would previously deadlock. [SF python bug #775414]
835
Vinay Sajip28e57612006-07-01 10:45:20 +0000836- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000837
Walter Dörwald4994d952006-06-19 08:07:50 +0000838- Patch #1506645: add Python wrappers for the curses functions
839 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000840
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000841Library
842-------
843
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000844- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
845 functions.
846
Martin v. Löwis3798da02006-06-17 18:44:27 +0000847- Patch #812986: Update turtle output even if not tracing.
848
Vinay Sajip28e57612006-07-01 10:45:20 +0000849- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000850 Tkinter.BaseWidget.
851
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000852- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
853
Martin v. Löwis337487e2006-06-17 09:15:14 +0000854- Patch #763580: Add name and value arguments to Tkinter variable
855 classes.
856
Georg Brandl83cc0d02006-06-14 08:50:03 +0000857- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
858 mime.types file for determining MIME types.
859
Georg Brandl2605ca82006-06-14 06:08:31 +0000860- Bug #1339007: Shelf objects now don't raise an exception in their
861 __del__ method when initialization failed.
862
Martin v. Löwisd8251432006-06-14 05:21:04 +0000863- Patch #1455898: The MBCS codec now supports the incremental mode for
864 double-byte encodings.
865
Tim Peters43898b42006-06-14 04:09:25 +0000866- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
867 guarantee that adjacent triples in the return list always describe
868 non-adjacent blocks. Previously, a pair of matching blocks could end
869 up being described by multiple adjacent triples that formed a partition
870 of the matching pair.
871
Greg Ward0e0c9f42006-06-11 16:24:11 +0000872- Bug #1498146: fix optparse to handle Unicode strings in option help,
873 description, and epilog.
874
Greg Wardd1c797e2006-06-11 14:42:41 +0000875- Bug #1366250: minor optparse documentation error.
876
Greg Ward7f547402006-06-11 00:40:49 +0000877- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
878 clarify docs.
879
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000880- The wsgiref package has been added to the standard library.
881
Nick Coghlan676725d2006-06-08 13:54:49 +0000882- The functions update_wrapper() and wraps() have been added to the functools
883 module. These make it easier to copy relevant metadata from the original
884 function when writing wrapper functions.
885
Tim Petersd6a9eef2006-06-05 01:48:21 +0000886- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
887 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000888
Martin v. Löwis3f767792006-06-04 19:36:28 +0000889- Patch #1359618: Speed up charmap encoder by using a trie structure
890 for lookup.
891
Tim Petersd609b1a2006-06-02 23:22:51 +0000892- The functions in the ``pprint`` module now sort dictionaries by key
893 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
894 if and only if its display required more than one line, although that
895 wasn't documented. The new behavior increases predictability; e.g.,
896 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
897
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000898- Patch #1497027: try HTTP digest auth before basic auth in urllib2
899 (thanks for J. J. Lee).
900
Georg Brandl2b330372006-05-28 20:23:12 +0000901- Patch #1496206: improve urllib2 handling of passwords with respect to
902 default HTTP and HTTPS ports.
903
George Yoshidaf3c65de2006-05-28 16:39:09 +0000904- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
905
Bob Ippolito7298f272006-05-23 18:43:47 +0000906- Patch #1281707: speed up gzip.readline.
907
Georg Brandlb89316f2006-05-17 15:51:16 +0000908- Patch #1180296: Two new functions were added to the locale module:
909 format_string() to get the effect of "format % items" but locale-aware,
910 and currency() to format a monetary number with currency sign.

Georg Brandle3a25832006-05-17 14:56:04 +0000912- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
913 and several features added, such as speed and geometry control.
914
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000915- Patch #1488881: add support for external file objects in bz2 compressed
916 tarfiles.
917
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000918- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
919 stdout arguments, making it possible to redirect input and output
920 for remote debugging.
921
922- Patch #1484695: Update the tarfile module to version 0.8. This fixes
923 a couple of issues, notably handling of long file names using the
924 GNU LONGNAME extension.
925
926- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
927 new flag when ``name`` is already the name of an option flag.
928
929- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
930 package.
931

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000968What's New in Python 2.5 alpha 2?
969=================================
970
971*Release date: 27-APR-2006*
972
973Core and builtins
974-----------------
975
Thomas Heller1b046642006-04-18 18:51:06 +0000976- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
977 by converting these apis from macros into exported functions again:
978
979 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
980 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
981 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
982 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
983 PyRun_String Py_CompileString
984
Martin v. Löwis45294a92006-04-18 06:24:08 +0000985- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
986
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000987- All uses of PyStructSequence_InitType have been changed to initialize
988 the type objects only once, even if the interpreter is initialized
989 multiple times.
990
Neal Norwitz61546162006-04-14 05:20:28 +0000991- Bug #1454485, array.array('u') could crash the interpreter. This was
992 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
993 to unicode when it didn't make sense. 'u#' now requires a unicode string.
994
995- Py_UNICODE is unsigned. It was always documented as unsigned, but
996 due to a bug had a signed value in previous versions.
997
Tim Peters3a5e8b12006-04-11 01:44:07 +0000998- Patch #837242: ``id()`` of any Python object always gives a positive
999 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1000 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001001 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001002 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001003
Tim Peters3a5e8b12006-04-11 01:44:07 +00001004 def __hash__(self):
1005 return id(self) # WRONG
1006
1007 because a hash result must be a (short) Python int but it was always
1008 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001009 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001010 was always usable as a hash value before this patch. That's no longer
1011 necessarily so.
1012
1013- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001014 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001015 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001016 #1454844)
1017
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001018- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1019 involving generators that have paused outside of any ``try`` or ``with``
1020 blocks. (In 2.5a1, a paused generator that was part of a reference
1021 cycle could not be garbage collected, regardless of whether it was
1022 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001023
Anthony Baxter51bcb682006-04-05 14:51:42 +00001024Extension Modules

1026
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001027- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1028 is a macro.
1029
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001030- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1031 fails with an error condition.
1032
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001033- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1034
1035- Bug #1117761: bsddb.*open() no longer raises an exception when using
1036 the cachesize parameter.
1037
1038- Bug #1149413: bsddb.*open() no longer raises an exception when using
1039 a temporary db (file=None) with the 'n' flag to truncate on open.
1040
1041- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1042 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001043
Armin Rigoa9017c32006-04-19 11:50:27 +00001044- Patch #1062014: AF_UNIX sockets under Linux have a special
1045 abstract namespace that is now fully supported.
1046
Anthony Baxter51bcb682006-04-05 14:51:42 +00001047Library
1048-------
1049
Peter Astrand7d1d4362006-07-14 14:04:45 +00001050- Bug #1223937: subprocess.CalledProcessError reports the exit status
1051 of the process using the returncode attribute, instead of
1052 abusing errno.
1053
Tim Peters711bf302006-04-25 03:31:36 +00001054- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1055 a doctest to be skipped (the code is not run, and the expected output
1056 or exception is ignored).
1057
Nick Coghlanda2268f2006-04-24 04:37:15 +00001058- Fixed contextlib.nested to cope with exceptions being raised and
1059 caught inside exit handlers.
1060
Greg Wardab05edc2006-04-23 03:47:58 +00001061- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1062 hex, octal, or binary; add ``append_const`` action; keep going if
1063 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1064 added ``epilog`` for better help generation).
1065
Tim Peters21fbd572006-04-21 21:18:10 +00001066- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1067 called from a thread spawned as a side effect of importing a module.
1068
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001069- The pydoc module now supports documenting packages contained in
1070 .zip or .egg files.
1071
1072- The pkgutil module now has several new utility functions, such
1073 as ``walk_packages()`` to support working with packages that are either
1074 in the filesystem or zip files.
1075
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001076- The mailbox module can now modify and delete messages from
1077 mailboxes, in addition to simply reading them. Thanks to Gregory
1078 K. Johnson for writing the code, and to the 2005 Google Summer of
1079 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001080
Tim Petersc7605f22006-04-17 21:12:33 +00001081- The ``__del__`` method of class ``local`` in module ``_threading_local``
1082 returned before accomplishing any of its intended cleanup.
1083
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001084- Patch #790710: Add breakpoint command lists in pdb.
1085
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001086- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +00001088- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1089
Anthony Baxtere29002c2006-04-12 12:07:31 +00001090- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1091 Windows. Bug #1469163.
1092
Phillip J. Eby47032112006-04-11 01:07:43 +00001093- The warnings, linecache, inspect, traceback, site, and doctest modules
1094 were updated to work correctly with modules imported from zipfiles or
1095 via other PEP 302 __loader__ objects.
1096
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001097- Patch #1467770: Reduce usage of subprocess._active to processes which
1098 the application hasn't waited on.
1099
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001100- Patch #1462222: Fix Tix.Grid.
1101
Neal Norwitza31bf182006-04-09 03:35:43 +00001102- Fix exception when doing glob.glob('anything*/')
1103
Skip Montanaro262fb922006-04-21 02:31:07 +00001104- The pstats.Stats class accepts an optional stream keyword argument to
1105 direct output to an alternate file-like object.
1106

1108-----
1109
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001110- The Makefile now has a reindent target, which runs reindent.py on
1111 the library.
1112
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001113- Patch #1470875: Building Python with MS Free Compiler
1114
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001115- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001116
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001117- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1118 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001119 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001120 CXX from --with-cxx-main, see description in README.
1121
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001122- Patch #1429775: Link extension modules with the shared libpython.
1123
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001124- Fixed a libffi build problem on MIPS systems.
1125
Tim Peters8931ff12006-05-13 23:28:20 +00001126- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1127 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1128 and "%zu" for unsigned integers of type ``size_t``.
1129
Anthony Baxter51bcb682006-04-05 14:51:42 +00001130Tests
1131-----
1132
Nick Coghlanda2268f2006-04-24 04:37:15 +00001133- test_contextlib now checks contextlib.nested can cope with exceptions
1134 being raised and caught inside exit handlers.
1135
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001136- test_cmd_line now checks operation of the -m and -c command switches
1137
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001138- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1139 it separately and by hand. It also wasn't cleaning up its changes to
1140 the current Decimal context.
1141
Thomas Woutersabd08882006-04-26 15:53:30 +00001142- regrtest.py now has a -M option to run tests that test the new limits of
1143 containers, on 64-bit architectures. Running these tests is only sensible
1144 on 64-bit machines with more than two gigabytes of memory. The argument
1145 passed is the maximum amount of memory for the tests to use.

1154-------------
1155
Tim Petersb06d28c2006-05-12 01:57:59 +00001156- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1157
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001158- PEP 343: Added Context Types section to the library reference
1159 and attempted to bring other PEP 343 related documentation into
1160 line with the implementation and/or python-dev discussions.
1161
Tim Peters8dc73d22006-04-24 02:03:16 +00001162- Bug #1337990: clarified that ``doctest`` does not support examples
1163 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001166What's New in Python 2.5 alpha 1?
1167=================================
1168
Anthony Baxterebed3f62006-04-03 15:03:44 +00001169*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001170
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001171Core and builtins
1172-----------------
1173
Nick Coghlan43832302006-04-23 17:04:07 +00001174- PEP 338: -m command line switch now delegates to runpy.run_module
1175 allowing it to support modules in packages and zipfiles
1176
Martin v. Löwisc661b882006-04-20 04:54:23 +00001177- On Windows, .DLL is not an accepted file name extension for
1178 extension modules anymore; extensions are only found if they
1179 end in .PYD.
1180
Martin v. Löwisea62d252006-04-03 10:56:49 +00001181- Bug #1421664: sys.stderr.encoding is now set to the same value as
1182 sys.stdout.encoding.
1183
Neal Norwitz92e212f2006-04-03 04:48:37 +00001184- __import__ accepts keyword arguments.
1185
Georg Brandlccadf842006-03-31 18:54:53 +00001186- Patch #1460496: round() now accepts keyword arguments.
1187
Anthony Baxter262c00a2006-03-30 10:53:17 +00001188- Fixed bug #1459029 - unicode reprs were double-escaped.
1189
Hye-Shik Changd478f342006-03-23 12:32:36 +00001190- Patch #1396919: The system scope threads are reenabled on FreeBSD
1191 5.4 and later versions.
1192
Neal Norwitze98ccf62006-03-23 05:39:47 +00001193- Bug #1115379: Compiling a Unicode string with an encoding declaration
1194 now gives a SyntaxError.
1195
Georg Brandlabd1ff82006-03-18 07:59:59 +00001196- Previously, Python code had no easy way to access the contents of a
1197 cell object. Now, a ``cell_contents`` attribute has been added
1198 (closes patch #1170323).
1199
Tim Peterscf79aac2006-03-16 01:14:46 +00001200- Patch #1123430: Python's small-object allocator now returns an arena to
1201 the system ``free()`` when all memory within an arena becomes unused
1202 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1203 freed. Some applications will see a drop in virtual memory size now,
1204 especially long-running applications that, from time to time, temporarily
1205 use a large number of small objects. Note that when Python returns an
1206 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001207 platform C library will in turn return that memory to the operating system.
1208 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001209 appears to be effective at least on Microsoft C and gcc-based systems.
1210 Thanks to Evan Jones for hard work and patience.
1211
Georg Brandl533ff6f2006-03-08 18:09:27 +00001212- Patch #1434038: property() now uses the getter's docstring if there is
1213 no "doc" argument given. This makes it possible to legitimately use
1214 property() as a decorator to produce a read-only property.
1215
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001216- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1217 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1218 of requiring an int or long in slicing and a few other contexts, enabling
1219 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1220
Neal Norwitz995acdf2006-03-07 05:01:00 +00001221- Fixed various bugs reported by Coverity's Prevent tool.
1222
Brett Cannonbf364092006-03-01 04:25:17 +00001223- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1224 new exception base class, BaseException, which has a new message attribute.
1225 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1226 Raising a string exception now raises a DeprecationWarning.
1227
Thomas Woutersfb609f42006-02-28 16:37:25 +00001228- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1229 explicitly relative, using 'from .module import name' to mean 'from the same
1230 package as this module is in. Imports without dots still default to the
1231 old relative-then-absolute, unless 'from __future__ import
1232 absolute_import' is used.
1233
Brett Cannona7446e32006-02-27 23:39:10 +00001234- Properly check if 'warnings' raises an exception (usually when a filter set
1235 to "error" is triggered) when raising a warning for raising string
1236 exceptions.
1237
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001238- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001239 The name was removed from Include/code.h.
1240
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001241- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001242
Guido van Rossum1968ad32006-02-25 22:38:04 +00001243- Patch 1433928:
1244 - The copy module now "copies" function objects (as atomic objects).
1245 - dict.__getitem__ now looks for a __missing__ hook before raising
1246 KeyError.
1247
Tim Peters84ef21c2006-02-28 20:39:06 +00001248- PEP 343: with statement implemented. Needs ``from __future__ import
1249 with_statement``. Use of 'with' as a variable will generate a warning.
1250 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001251 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001252 The following objects have __context__ methods:
1253 - The built-in file type.
1254 - The thread.LockType type.
1255 - The following types defined by the threading module:
1256 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1257 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001258
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001259- Fix the encodings package codec search function to only search
1260 inside its own package. Fixes problem reported in patch #1433198.
1261
1262 Note: Codec packages should implement and register their own
1263 codec search function. PEP 100 has the details.
1264
Tim Peters9ea89d22006-06-04 03:26:02 +00001265- PEP 353: Using ``Py_ssize_t`` as the index type.
1266
1267- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1268 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1269 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1270 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1271 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001272
Neal Norwitzfc76d632006-01-10 06:03:13 +00001273- Patch #1400181, fix unicode string formatting to not use the locale.
1274 This is how string objects work. u'%f' could use , instead of .
1275 for the decimal point. Now both strings and unicode always use periods.
1276
Neal Norwitz671b9e32006-01-09 07:07:12 +00001277- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1278 configure would break checking curses.h.
1279
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001280- Bug #959576: The pwd module is now builtin. This allows Python to be
1281 built on UNIX platforms without $HOME set.
1282
Neal Norwitzc10978f2005-12-19 06:07:16 +00001283- Bug #1072182, fix some potential problems if characters are signed.
1284
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001285- Bug #889500, fix line number on SyntaxWarning for global declarations.
1286
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001287- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1288
Neal Norwitze7214a12005-12-18 05:03:17 +00001289- Support for converting hex strings to floats no longer works.
1290 This was not portable. float('0x3') now raises a ValueError.
1291
Barry Warsaw2a38a862005-12-18 01:27:35 +00001292- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001293 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001294 is now displayed in interactive prompt banner.
1295
Georg Brandlfa166682005-12-17 21:45:17 +00001296- Implementation of PEP 341 - Unification of try/except and try/finally.
1297 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001298 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001299
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001300- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1301 now encodes backslash correctly.
1302
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001303- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1304
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001305- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001306 and long longs.
1307
Neal Norwitz67715f02005-11-09 06:59:35 +00001308- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001309 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001310 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001311
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001312- Replaced most Unicode charmap codecs with new ones using the
1313 new Unicode translate string feature in the builtin charmap
1314 codec; the codecs were created from the mapping tables available
1315 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1316 encodings now include a mapping for the Apple logo)
1317
Tim Peterse3547fd2005-12-16 23:13:57 +00001318- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001319
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001320- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001321
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001322- A new AST parser implementation was completed. The abstract
1323 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001324 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001325
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001326- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001327 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1328
Neal Norwitz708e51a2005-10-03 04:48:15 +00001329- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1330
Neal Norwitz11bd1192005-10-03 00:54:56 +00001331- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1332 Provide a warning when a directory is passed on the command line.
1333
Neal Norwitz40d37812005-10-02 01:48:49 +00001334- Fix segfault with invalid coding.
1335
1336- SF bug #772896: unknown encoding results in MemoryError.
1337
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001338- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001339 supported a __len__() method which evaluated to False when the iterator
1340 was empty.
1341
Guido van Rossum630db602005-09-20 18:49:54 +00001342- On 64-bit platforms, when __len__() returns a value that cannot be
1343 represented as a C int, raise OverflowError.
1344
Skip Montanarof8948ca2005-09-19 03:54:46 +00001345- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001346 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001347
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001348- SF bug #893549: parsing keyword arguments was broken with a few format
1349 codes.
1350
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001351- Changes donated by Elemental Security to make it work on AIX 5.3
1352 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1353 bug #105470: test_pwd fails on 64bit system (Opteron).
1354
Guido van Rossum539c6622005-09-14 17:49:54 +00001355- Changes donated by Elemental Security to make it work on HP-UX 11 on
1356 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1357
Georg Brandl4550b8d2005-08-26 06:43:52 +00001358- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001359 (fixes bug #1119418).
1360
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001361- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1362
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001363- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1364 exceptions that cause a function to exit.
1365
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001366- The implementation of set() and frozenset() was revised to use its
1367 own internal data structure. Memory consumption is reduced by 1/3
1368 and there are modest speed-ups as well. The API is unchanged.
1369
Tim Petersde7990b2005-07-17 23:45:23 +00001370- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1371
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001372- SF bug #1229429: PyObject_CallMethod failed to decrement some
1373 reference counts in some error exit cases.
1374
Tim Petersecc6e6a2005-07-10 22:30:55 +00001375- SF bug #1185883: Python's small-object memory allocator took over
1376 a block managed by the platform C library whenever a realloc specified
1377 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001378 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001379 portable way to copy data from the C-managed block into Python's
1380 small-object space without risking a memory fault. Python's small-object
1381 realloc now leaves such blocks under the control of the platform C
1382 realloc.
1383
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001384- SF bug #1232517: An overflow error was not detected properly when
1385 attempting to convert a large float to an int in os.utime().
1386
Raymond Hettinger3296e692005-06-29 23:29:56 +00001387- SF bug #1224347: hex longs now print with lowercase letters just
1388 like their int counterparts.
1389
Michael W. Hudson188d4362005-06-20 16:52:57 +00001390- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1391 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1392 interpreter states; back out that fix and do a better job (see
1393 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1394 for a longer write-up of the problem).
1395
Michael W. Hudsondf888462005-06-03 14:41:55 +00001396- SF patch #1180995: marshal now uses a binary format by default when
1397 serializing floats.
1398
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001399- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1400 the routines that promise to produce IEEE 754 binary representations
1401 of floats now simply copy bytes around.
1402
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001403- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1404 278.
1405
Brett Cannonc3647ac2005-04-26 03:45:26 +00001406- patch #1109424: int, long, float, complex, and unicode now check for the
1407 proper magic slot for type conversions when subclassed. Previously the
1408 magic slot was ignored during conversion. Semantics now match the way
1409 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001410 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001411 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001412 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001413
Barry Warsawc8d907c2005-04-19 23:43:40 +00001414- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1415 NULL, now raise an AttributeError when attempting to set or delete the
1416 attribute. Previously a TypeError was raised, but this was inconsistent
1417 with the equivalent pure-Python implementation.
1418
Michael W. Hudson774479c2005-04-18 08:46:17 +00001419- It is now safe to call PyGILState_Release() before
1420 PyEval_InitThreads() (note that if there is reason to believe there
1421 are multiple threads around you still must call PyEval_InitThreads()
1422 before using the Python API; this fix is for extension modules that
1423 have no way of knowing if Python is multi-threaded yet).
1424
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001425- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1426 disabled caused a crash.
1427
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001428- Bug #1165306: instancemethod_new allowed the creation of a method
1429 with im_class == im_self == NULL, which caused a crash when called.
1430
Tim Petersecc6e6a2005-07-10 22:30:55 +00001431- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001432 fixes the crash seen in bug #1165761
1433
Raymond Hettinger96229b12005-03-11 06:49:40 +00001434- Added two new builtins, any() and all().
1435
Brett Cannon409d8f22005-03-05 06:47:57 +00001436- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001437 (e.g., ``class C(): pass`` is no longer a syntax error).
1438 Patch #1176012 added support to the 'parser' module and 'compiler' package
1439 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001440
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001441- Patch #1115086: Support PY_LONGLONG in structmember.
1442
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001443- Bug #1155938: new style classes did not check that __init__() was
1444 returning None.
1445
Tim Petersecc6e6a2005-07-10 22:30:55 +00001446- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001447 ('\') with a specific error message.
1448
Martin v. Löwisff232d72005-03-03 09:24:38 +00001449- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1450
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001451- Bug #1124295: the __name__ attribute of file objects was
1452 inadvertently made inaccessible in restricted mode.
1453
Tim Petersecc6e6a2005-07-10 22:30:55 +00001454- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001455 an ferror() call.
1456
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001457- min() and max() now support key= arguments with the same meaning as in
1458 list.sort().
1459
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001460- The peephole optimizer now performs simple constant folding in expressions:
1461 (2+3) --> (5).
1462
Raymond Hettingera422c342005-01-11 03:03:27 +00001463- set and frozenset objects can now be marshalled. SF #1098985.
1464
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001465- Bug #1077106: Poor argument checking could cause memory corruption
1466 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001467
Jeremy Hyltonab630502005-02-04 18:44:06 +00001468- The parser did not complain about future statements in illegal
1469 positions. It once again reports a syntax error if a future
1470 statement occurs after anything other than a doc string.
1471
Neil Schemenauercf52c072005-08-12 17:34:58 +00001472- Change the %s format specifier for str objects so that it returns a
1473 unicode instance if the argument is not an instance of basestring and
1474 calling __str__ on the argument returns a unicode instance.
1475
Tim Petersf4e69282006-02-27 17:15:31 +00001476- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1477 current thread state when the auto-GIL-state machinery knows about
1478 it (since the thread state is being deleted, continuing to remember it
1479 can't help, but can hurt if another thread happens to get created with
1480 the same thread id).
1481
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001482Extension Modules
1483-----------------
1484
Georg Brandl43f08a82006-03-31 18:01:16 +00001485- Patch #1380952: fix SSL objects timing out on consecutive read()s
1486
Neal Norwitz05a45592006-03-20 06:30:08 +00001487- Patch #1309579: wait3 and wait4 were added to the posix module.
1488

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001672- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1673 been renamed to have only a single underscore prefix. This was done to
1674 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001675
Nick Coghlan43832302006-04-23 17:04:07 +00001676- PEP 338: new module runpy defines a run_module function to support
1677 executing modules which provide access to source code or a code object
1678 via the PEP 302 import mechanisms.
1679
Anthony Baxter93f5b932006-04-03 08:05:07 +00001680- The email module's parsedate_tz function now sets the daylight savings

1688 in attribute values.
1689
Anthony Baxterc51ee692006-04-01 00:57:31 +00001690- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001691 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001692 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001693 module will not be built.
1694
Tim Petersc17976e2006-04-01 00:26:53 +00001695- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1696 aren't officially supported here, and trying to use them will probably
1697 raise an exception some day. But dicts have been allowed, and "mostly
1698 worked", so support for them won't go away without warning.
1699
Georg Brandl338ef7d2006-03-31 18:42:16 +00001700- Bug #1445068: getpass.getpass() can now be given an explicit stream
1701 argument to specify where to write the prompt.
1702

1718
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001719- email 4.0 package now integrated. This is largely the same as the email 3.0
1720 package that was included in Python 2.3, except that PEP 8 module names are
1721 now used (e.g. mail.message instead of email.Message). The MIME classes
1722 have been moved to a subpackage (e.g. email.mime.text instead of
1723 email.MIMEText). The old names are still supported for now. Several
1724 deprecated Message methods have been removed and lots of bugs have been
1725 fixed. More details can be found in the email package documentation.
1726
Walter Dörwald40108c92006-03-27 08:15:44 +00001727- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1728 (a subclass of tuple) that provides incremental decoders and encoders
1729 (a way to use stateful codecs without the stream API). Python functions
1730 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1731 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1732 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001734- Patch #1359365: Calling next() on a closed StringIO.String object raises
1735 a ValueError instead of a StopIteration now (like file and cString.String do).
1736 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1737 called before (like file and StringIO.StringIO do).

1815
1816 "The consensus of researchers in this area (at least as
1817 expressed at the NIST Hash Function Workshop 10/31/05),
1818 is that SHA-256 is a good choice for the time being, but
1819 that research should continue, and other alternatives may
1820 arise from this research. The larger SHA's also seem OK."

2009 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002010 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002011 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002012 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2013 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002014 + reader now allows \r characters to be quoted (previously it only allowed
2015 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002016 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002017 + Dialect classes passed to the module are no longer instantiated by
2018 the module before being parsed (the former validation scheme required
2019 this, but the mechanism was unreliable).
2020 + The dialect registry now contains instances of the internal
2021 C-coded dialect type, rather than references to python objects.
2022 + the internal c-coded dialect type is now immutable.
2023 + register_dialect now accepts the same keyword dialect specifications
2024 as the reader and writer, allowing the user to register dialects
2025 without first creating a dialect class.
2026 + a configurable limit to the size of parsed fields has been added -
2027 previously, an unmatched quote character could result in the entire
2028 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002029 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002030 the parser field size limit (returning the former limit). The initial
2031 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002032 + A line_num attribute has been added to the reader object, which tracks
2033 the number of lines read from the source iterator. This is not
2034 the same as the number of records returned, as records can span
2035 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002036 + reader and writer objects were not being registered with the cyclic-GC.
2037 This has been fixed.
2038
Brett Cannone6539c42005-01-08 02:43:53 +00002039- _DummyThread objects in the threading module now delete self.__block that is
2040 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2041 lock primitives tend to be limited in number and thus should not be wasted on
2042 a _DummyThread object. Fixes bug #1089632.
2043
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002044- The imghdr module now detects Exif files.
2045
Raymond Hettinger6065d322004-12-20 23:51:53 +00002046- StringIO.truncate() now correctly adjusts the size attribute.
2047 (Bug #951915).
2048
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002049- locale.py now uses an updated locale alias table (built using
2050 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2051 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002052 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002053
Raymond Hettinger3557f422004-12-07 12:02:02 +00002054- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2055
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002056- the pickle module no longer accepts the deprecated None option in the
2057 args tuple returned by __reduce__().
2058
Brett Cannon84667c02004-12-07 03:25:18 +00002059- optparse now optionally imports gettext. This allows its use in setup.py.
2060
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002061- the pickle module no longer uses the deprecated bin parameter.
2062
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002063- the shelve module no longer uses the deprecated binary parameter.
2064

2066
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002067- the filecmp module no longer uses the deprecated use_statcache argument.
2068
Raymond Hettinger664347b2004-12-04 21:21:53 +00002069- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2070 extended or overridden by subclasses. Formerly, the subclassed method would
2071 be ignored by the rest of the module. (Bug #1078905).
2072
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002073- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002074 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002075
Walter Dörwald36733692004-12-22 12:50:50 +00002076- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2077 once when a size argument is given. This prevents a buffer overflow in the
2078 tokenizer with very long source lines.
2079
Barry Warsaw538561e2006-01-01 21:48:54 +00002080- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2081 immediately after creating the object, without any intervening
2082 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002083
Skip Montanaro05885812005-01-16 20:48:27 +00002084- The reconvert.quote function can now emit triple-quoted strings. The
2085 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002086
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002087- ``UserString.MutableString`` now supports negative indices in
2088 ``__setitem__`` and ``__delitem__``
2089
Greg Ward40407942005-03-05 02:53:17 +00002090- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2091 correctly.
2092
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002093- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2094 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2095 character even if the user has passed a size parameter to get a proper
2096 line ending. Remove the special handling of a "\r\n" that has been split
2097 between two lines.
2098
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002099- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2100 about illegal code points. The codec now supports PEP 293 style error
2101 handlers.
2102
Walter Dörwald78a78b02005-09-01 12:04:29 +00002103- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002104 from the input stream, so that the output is a byte string in the correct
2105 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002106
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002107- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2108 considering it exactly like a '*'.
2109
Walter Dörwald007f8df2005-10-09 19:42:27 +00002110- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2111 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002112
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002113- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2114
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002115- Patch #1413711: Certain patterns of differences were making difflib
2116 touch the recursion limit.
2117
Walter Dörwald58917a62006-03-31 15:26:22 +00002118- Bug #947906: An object oriented interface has been added to the calendar
2119 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002120 called as a script (e.g. via ``python -mcalendar``). Localized month and
2121 weekday names can be ouput (even if an exotic encoding is used) using
2122 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002123
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002124Build
2125-----
2126
Neal Norwitz602d3392006-03-31 08:21:40 +00002127- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2128 by using -mieee gcc option.
2129
Martin v. Löwis86d66262006-02-17 08:40:11 +00002130- Patch #1432345: Make python compile on DragonFly.
2131
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002132- Build support for Win64-AMD64 was added.
2133
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002134- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2135
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002136- Patch #881820: look for openpty and forkpty also in libbsd.
2137
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002138- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2139 The zlib module is now builtin on Windows.
2140
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002141- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2142
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002143- Bug #1189330: configure did not correctly determine the necessary
2144 value of LINKCC if python was built with GCC 4.0.
2145
Trent Mick8321b422005-07-26 02:29:21 +00002146- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2147 vulnerability in zlib 1.2.1 and 1.2.2.
2148
Brett Cannon08cd5982005-04-24 22:26:38 +00002149- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2150 flags that change binary compatibility. Changes were also made to
2151 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002152 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002153
Bob Ippolitoed233462005-03-29 13:47:59 +00002154- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2155 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2156 no longer exists). This configure patch makes things right.
2157
Martin v. Löwise2713be2005-03-08 15:03:08 +00002158- Bug #1158607: Build with --disable-unicode again.
2159
Brett Cannon46d96232005-02-16 00:07:19 +00002160- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2161 defined. Discovered as a result of not being able to build on OS X.
2162
Brett Cannon516592f2004-12-07 00:42:59 +00002163- setup.py now uses the directories specified in LDFLAGS using the -L option
2164 and in CPPFLAGS using the -I option for adding library and include
2165 directories, respectively, for compiling extension modules against. This has
2166 led to the core being compiled using the values in CPPFLAGS. It also removes
2167 the need for the special-casing of both DarwinPorts and Fink for darwin since
2168 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2169 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2170 Fink, ``-I/opt/local/include`` for DarwinPorts).
2171
Brett Cannon43802422005-02-10 20:48:03 +00002172- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2173 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2174 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2175 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002177C API
2178-----
2179
Tim Petersc9d78aa2006-03-26 23:27:58 +00002180- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2181 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2182 is obtained via the ``PyObject_`` family, it must be released via the
2183 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2184 always been officially true, but when Python's small-object allocator was
2185 introduced, an attempt was made to cater to a few extension modules
2186 discovered at the time that obtained memory via ``PyObject_New`` but
2187 released it via ``PyMem_DEL``. It's years later, and if such code still
2188 exists it will fail now (probably with segfaults, but calling wrong
2189 low-level memory management functions can yield many symptoms).
2190
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002191- Added a C API for set and frozenset objects.
2192
Raymond Hettinger66517482004-12-03 11:45:13 +00002193- Removed PyRange_New().
2194
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002195- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2196 mapping argument now. This string is used as a mapping table. Byte values
2197 greater than the length of the string and 0xFFFE are treated as undefined
2198 mappings.
