13-----------------
14
Georg Brandla10d3af2006-09-24 12:35:36 +000015- Fix a bug in the parser's future statement handling that led to "with"
16 not being recognized as a keyword after, e.g., this statement:
17 from __future__ import division, with_statement
18
Neal Norwitz3a230172006-09-22 08:18:10 +000019- Bug #1557232: fix seg fault with def f((((x)))) and def f(((x),)).

24
Brett Cannon9adeab72006-09-20 18:34:28 +000025- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
26 allows calling unicode() on exceptions classes directly to succeed.
27
Georg Brandlec6c2df2006-09-11 09:38:35 +000028- Make _PyGILState_NoteThreadState() static, it was not used anywhere
29 outside of pystate.c and should not be necessary.
30
Georg Brandl4e933132006-09-06 20:05:58 +000031- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
32 Also make sure that every exception class has __module__ set to
33 'exceptions'.
34
Georg Brandl98775df2006-09-06 06:09:31 +000035- Bug #1550983: emit better error messages for erroneous relative
36 imports (if not in package and if beyond toplevel package).
37
Tim Petersc10c9d02006-09-05 02:18:09 +000038- Overflow checking code in integer division ran afoul of new gcc
39 optimizations. Changed to be more standard-conforming.
40

44
Neal Norwitzd34e4272006-09-05 02:36:20 +000045- The return tuple from str.rpartition(sep) is (tail, sep, head) where
46 head is the original string if sep was not found.
47
Neal Norwitzdac090d2006-09-05 03:53:08 +000048- Bug #1520864: unpacking singleton tuples in list comprehensions and
49 generator expressions (x for x, in ... ) works again. Fixing this problem
50 required changing the .pyc magic number. This means that .pyc files
51 generated before 2.5c2 will be regenerated.
52
Neal Norwitzca460d92006-09-06 06:28:06 +000053- with and as are now keywords.

63 being raised when print_exc() was called without an exception set.
64 In version 2.4, this printed "None", restored that behavior.
65
Georg Brandl2c94bf72006-09-24 10:36:01 +000066- Make webbrowser.BackgroundBrowser usable in Windows (it wasn't because
67 the close_fds arg to subprocess.Popen is not supported).
68

Guido van Rossumc69ac252006-08-10 18:09:25 +0000151What's New in Python 2.5 release candidate 1?
152=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000153
Anthony Baxterb4096662006-08-16 03:42:26 +0000154*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000155
156Core and builtins
157-----------------
158
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000159- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000160 compared equal or unequal to a string and a UnicodeDecodeError
161 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000162
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000163 Instead, the equal (==) and unequal (!=) comparison operators will
164 now issue a UnicodeWarning and interpret the two objects as
165 unequal. The UnicodeWarning can be filtered as desired using
166 the warning framework, e.g. silenced completely, turned into an
167 exception, logged, etc.
168
169 Note that compare operators other than equal and unequal will still
170 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000171
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000172- Fix segfault when doing string formatting on subclasses of long.
173
174- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
175 with new-style classes.
176
177- Fix bug related to __len__ functions returning negative values with
178 classic classes.
179
180- Patch #1538606, Fix __index__() clipping. There were some problems
181 discovered with the API and how integers that didn't fit into Py_ssize_t
182 were handled. This patch attempts to provide enough alternatives
183 to effectively use __index__.
184
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000185- Bug #1536021: __hash__ may now return long int; the final hash
186 value is obtained by invoking hash on the long int.
187
Thomas Hellerab1049c2006-08-08 17:37:00 +0000188- Bug #1536786: buffer comparison could emit a RuntimeWarning.
189
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000190- Bug #1535165: fixed a segfault in input() and raw_input() when
191 sys.stdin is closed.
192
Thomas Heller74d36f02006-08-04 18:17:40 +0000193- On Windows, the PyErr_Warn function is now exported from
194 the Python dll again.
195
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000196- Bug #1191458: tracing over for loops now produces a line event
197 on each iteration. Fixing this problem required changing the .pyc
198 magic number. This means that .pyc files generated before 2.5c1
199 will be regenerated.
200
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000201- Bug #1333982: string/number constants were inappropriately stored
202 in the byte code and co_consts even if they were not used, ie
203 immediately popped off the stack.
204
Georg Brandle9462c72006-08-04 18:03:37 +0000205- Fixed a reference-counting problem in property().
206
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000207
208Library
209-------
210
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000211- Fix a bug in the ``compiler`` package that caused invalid code to be
212 generated for generator expressions.
213
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000214- The distutils version has been changed to 2.5.0. The change to
215 keep it programmatically in sync with the Python version running
216 the code (introduced in 2.5b3) has been reverted. It will continue
217 to be maintained manually as static string literal.
218
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000219- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000220 and this cannot be converted to the required C type, an exception is
221 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000222 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000223
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000224- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000225 an exception.
226
Tim Petersc10c9d02006-09-05 02:18:09 +0000227- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000228 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000229 workarounds for clocks with low resolution, to stop the code yielding
230 duplicate UUIDs.
231
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000232- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
233 before raising SystemExit, allowing IDLE to honor quit() and exit().
234
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000235- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
236
Georg Brandl7a1af772006-08-14 21:55:28 +0000237- Patch #1536071: trace.py should now find the full module name of a
238 file correctly even on Windows.
239
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000240- logging's atexit hook now runs even if the rest of the module has
241 already been cleaned up.
242
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000243- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000244
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000245- Bug #1531405, format_exception no longer raises an exception if
246 str(exception) raised an exception.
247
Neil Schemenauer06ded092006-08-04 16:20:30 +0000248- Fix a bug in the ``compiler`` package that caused invalid code to be
249 generated for nested functions.

262
Thomas Heller86720042006-08-14 11:17:48 +0000263- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
264 uses the _as_parameter_ attribute when objects are passed to foreign
265 function calls. The ctypes version number was changed to 1.0.1.
266
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000267- Bug #1530559, struct.pack raises TypeError where it used to convert.
268 Passing float arguments to struct.pack when integers are expected
269 now triggers a DeprecationWarning.

320-----------------
321
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000322- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000323 returned a long (see PEP 353).
324
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000325- Bug #1515471: string.replace() accepts character buffers again.
326
Neal Norwitz07aadb12006-07-30 06:55:48 +0000327- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
328 This provides the proper warning for struct.pack().
329 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
330
Neal Norwitz0d62a062006-07-30 06:53:31 +0000331- Patch #1531113: Fix augmented assignment with yield expressions.
332 Also fix a SystemError when trying to assign to yield expressions.
333
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000334- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
335 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
336 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
337 excessive filesystem operations during imports.
338
Tim Petersbc24eee2006-07-27 01:14:53 +0000339- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
340 operations on signed longs that are formally undefined by C.
341 Unfortunately, at least one compiler now cares about that, so complicated
342 the code to make that compiler happy again.
343
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000344- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
345
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000346- Patch #1232023: Stop including current directory in search
347 path on Windows.
348
Neal Norwitze1fdb322006-07-21 05:32:28 +0000349- Fix some potential crashes found with failmalloc.
350
Neal Norwitze7563102006-07-17 01:00:16 +0000351- Fix warnings reported by Klocwork's static analysis tool.
352
Neal Norwitz84be93b2006-07-16 01:50:38 +0000353- Bug #1512814, Fix incorrect lineno's when code within a function
354 had more than 255 blank lines.
355
Georg Brandl9dceedb2006-07-12 15:31:17 +0000356- Patch #1521179: Python now accepts the standard options ``--help`` and
357 ``--version`` as well as ``/?`` on Windows.
358
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000359- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000360 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000361 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000362
Tim Peters112aad32006-07-19 00:03:19 +0000363- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000364 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000365 new ``sys._current_frames()`` returns a dictionary with one entry,
366 mapping the faux "thread id" 0 to the current frame.
367
Ronald Oussoren3075e162006-07-25 20:28:55 +0000368- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000369

372-------
373
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000374- Correction of patch #1455898: In the mbcs decoder, set final=False
375 for stream decoder, but final=True for the decode function.
376
Georg Brandl07fec3a2006-08-01 18:49:24 +0000377- os.urandom no longer masks unrelated exceptions like SystemExit or
378 KeyboardInterrupt.
379
Tim Peters4643c2f2006-08-10 22:45:34 +0000380- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000381 shutil.copytree on Windows
382
Georg Brandle34ac7c2006-07-30 11:07:23 +0000383- Bug #1002398: The documentation for os.path.sameopenfile now correctly
384 refers to file descriptors, not file objects.
385
Tim Petersc10c9d02006-09-05 02:18:09 +0000386- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000387 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000388 #1513611, and probably others.
389
Georg Brandledd9b0d2006-07-29 09:33:26 +0000390- Bug #1441397: The compiler module now recognizes module and function
391 docstrings correctly as it did in Python 2.4.
392
Tim Peters6f681472006-07-27 23:44:37 +0000393- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
394 lost that tests are sorted by name before being run. This rarely
395 matters for well-written tests, but can create baffling symptoms if
396 side effects from one test to the next affect outcomes. ``DocTestFinder``
397 has been changed to sort the list of tests it returns.
398
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000399- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000400 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000401
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000402- Bug #978833: Really close underlying socket in _socketobject.close.
403
Georg Brandl8c036cc2006-08-20 13:15:39 +0000404- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
405 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000406
Georg Brandlcf0c1722006-07-26 07:23:32 +0000407- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
408 to recursive calls and call it with the failing package name.
409
Martin v. Löwis0b483032006-07-25 09:53:12 +0000410- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
411
Georg Brandlc13c34c2006-07-24 14:09:56 +0000412- Patch #1515343: Fix printing of deprecated string exceptions with a
413 value in the traceback module.
414
Greg Ward48fae7a2006-07-23 16:05:51 +0000415- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
416
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000417- Patch #1524429: Use repr() instead of backticks in Tkinter again.
418
Brett Cannoncaebe222006-07-18 04:41:36 +0000419- Bug #1520914: Change time.strftime() to accept a zero for any position in its
420 argument tuple. For arguments where zero is illegal, the value is forced to
421 the minimum value that is correct. This is to support an undocumented but
422 common way people used to fill in inconsequential information in the time
423 tuple pre-2.4.
424
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000425- Patch #1220874: Update the binhex module for Mach-O.
426
Barry Warsawb110bad2006-07-21 14:51:07 +0000427- The email package has improved RFC 2231 support, specifically for
428 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
429 (name*0=<blah>) parameter continuations. This may change the types of
430 values returned from email.message.Message.get_param() and friends.
431 Specifically in some cases where non-encoded continuations were used,
432 get_param() used to return a 3-tuple of (None, None, string) whereas now it
433 will just return the string (since non-encoded continuations don't have
434 charset and language parts).
435
436 Also, whereas % values were decoded in all parameter continuations, they are
437 now only decoded in encoded parameter parts.
438
Ronald Oussoren3075e162006-07-25 20:28:55 +0000439- Bug #1517990: IDLE keybindings on MacOS X now work correctly
440
441- Bug #1517996: IDLE now longer shows the default Tk menu when a
442 path browser, class browser or debugger is the frontmost window on MacOS X
443
Barry Warsaw00decd72006-07-27 23:43:15 +0000444- Patch #1520294: Support for getset and member descriptors in types.py,
445 inspect.py, and pydoc.py. Specifically, this allows for querying the type
446 of an object against these built-in types and more importantly, for getting
447 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +0000450Extension Modules
451-----------------
452
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000453- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
454 a socket operation on a socket with a timeout, the exception will be
455 caught correctly. Previously, the exception was not caught.
456
Thomas Heller1393d6a2006-07-28 21:43:20 +0000457- Patch #1529514: The _ctypes extension is now compiled on more
458 openbsd target platforms.
459
Tim Peters9cab5932006-07-28 00:30:00 +0000460- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
461 a memory leak, affecting pickles and deep copies.
462
Tim Petersbc24eee2006-07-27 01:14:53 +0000463- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000464 Paul Eggert.
465
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000466- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
467
Thomas Hellerce049a02006-07-14 17:51:14 +0000468- Patch #1521817: Index range checking on ctypes arrays containing
469 exactly one element enabled again. This allows iterating over these
470 arrays, without the need to check the array size before.
471
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000472- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000473 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000474 /dev/null in certain cases; this is now fixed.
475
Thomas Heller47d7a062006-07-12 08:43:47 +0000476- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
477 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000478
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000479- Because of a misspelled preprocessor symbol, ctypes was always
480 compiled without thread support; this is now fixed.
481
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000482- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
483 methods now allow their database parameter to be None as the
484 sleepycat API allows.
485
Matt Flemingec926502006-07-28 11:27:27 +0000486- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
487 bluetooth API compared with Linux and FreeBSD.
488
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000489Tests
490-----
491
492- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
493 how long the test file should take to play. Now accepts taking 2.93 secs
494 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
495
Georg Brandl4793aa32006-07-28 18:31:39 +0000496- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
497 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
498 run via ``regrtest.py``. Now they do.

Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000500Build
501-----
502
503- Bug #1439538: Drop usage of test -e in configure as it is not portable.
504
Ronald Oussoren26cad082006-08-01 21:00:57 +0000505Mac
506---
507
508- PythonLauncher now works correctly when the path to the script contains
509 characters that are treated specially by the shell (such as quotes).
510
511- Bug #1527397: PythonLauncher now launches scripts with the working directory
512 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000513 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000514 expect.

522Core and builtins
523-----------------
524
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000525- Bug #1441486: The literal representation of -(sys.maxint - 1)
526 again evaluates to a int object, not a long.
527
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000528- Bug #1501934: The scope of global variables that are locally assigned
529 using augmented assignment is now correctly determined.
530
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000531- Bug #927248: Recursive method-wrapper objects can now safely
532 be released.
533
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000534- Bug #1417699: Reject locale-specific decimal point in float()
535 and atof().
536
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000537- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
538 omit a default "error" argument for NULL pointer. This allows
539 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000540
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000541- Bug #1519018: 'as' is now validated properly in import statements.
542
Neal Norwitz28746ab2006-07-09 22:14:42 +0000543- On 64 bit systems, int literals that use less than 64 bits are
544 now ints rather than longs.
545
Neal Norwitzed657552006-07-10 00:04:44 +0000546- Bug #1512814, Fix incorrect lineno's when code at module scope
547 started after line 256.
548
Tim Peters32a83612006-07-10 21:08:24 +0000549- New function ``sys._current_frames()`` returns a dict mapping thread
550 id to topmost thread stack frame. This is for expert use, and is
551 especially useful for debugging application deadlocks. The functionality
552 was previously available in Fazal Majid's ``threadframe`` extension
553 module, but it wasn't possible to do this in a wholly threadsafe way from
554 an extension.

557-------
558
Martin v. Löwis77621582006-07-30 13:27:31 +0000559- Bug #1257728: Mention Cygwin in distutils error message about a missing

563
Tim Peters32a83612006-07-10 21:08:24 +0000564- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000565 environment variable to be set in order to the SDK environment
566 for finding the compiler, include files, etc.
567
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000568- Bug #1515998: Properly generate logical ids for files in bdist_msi.

Nick Coghlan2d792252006-07-06 13:47:18 +0000570- warnings.py now ignores ImportWarning by default
571
Thomas Woutersadd19112006-07-05 11:03:49 +0000572- string.Template() now correctly handles tuple-values. Previously,
573 multi-value tuples would raise an exception and single-value tuples would
574 be treated as the value they contain, instead.
575
Martin v. Löwisede77f52006-07-03 13:01:35 +0000576- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
577 even if some data are received.
578
Martin v. Löwis45482392006-07-03 12:28:58 +0000579- Bug #1267547: Put proper recursive setup.py call into the
580 spec file generated by bdist_rpm.
581
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000582- Bug #1514693: Update turtle's heading when switching between
583 degrees and radians.
584
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000585- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000586 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000587
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000588- Bug #1514703: Only setup canvas window in turtle when the canvas
589 is created.
590
Martin v. Löwis7596e832006-07-01 15:33:37 +0000591- Bug #1513223: .close() of a _socketobj now releases the underlying
592 socket again, which then gets closed as it becomes unreferenced.
593
Fred Drake10497c82006-06-29 02:57:48 +0000594- Bug #1504333: Make sgmllib support angle brackets in quoted
595 attribute values.
596
597- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
598 sgmllib ('[' and ']' were not accepted).
599
Georg Brandl1be63af2006-06-28 20:23:25 +0000600- Fix a bug in the turtle module's end_fill function.
601
Brett Cannon53ab5b72006-06-22 16:49:14 +0000602- Bug #1510580: The 'warnings' module improperly required that a Warning
603 category be either a types.ClassType and a subclass of Warning. The proper
604 check is just that it is a subclass with Warning as the documentation states.
605
Georg Brandlad29e632006-06-21 17:45:17 +0000606- The compiler module now correctly compiles the new try-except-finally
607 statement (bug #1509132).
608
Neal Norwitz60373cd2006-06-22 06:30:50 +0000609- The wsgiref package is now installed properly on Unix.
610
Vinay Sajip28e57612006-07-01 10:45:20 +0000611- A bug was fixed in logging.config.fileConfig() which caused a crash on
612 shutdown when fileConfig() was called multiple times.
613
Gerhard Häring762fbd32006-07-02 17:48:30 +0000614- The sqlite3 module did cut off data from the SQLite database at the first
615 null character before sending it to a custom converter. This has been fixed
616 now.

619-----------------
620
Tim Peters112aad32006-07-19 00:03:19 +0000621- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
622 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
623 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000624
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000625- Assigning None to pointer type fields in ctypes structures possible
626 overwrote the wrong fields, this is fixed now.
627
628- Fixed a segfault in _ctypes when ctypes.wintypes were imported
629 on non-Windows platforms.
630
631- Bug #1518190: The ctypes.c_void_p constructor now accepts any
632 integer or long, without range checking.
633
634- Patch #1517790: It is now possible to use custom objects in the ctypes
635 foreign function argtypes sequence as long as they provide a from_param
636 method, no longer is it required that the object is a ctypes type.
637
638- The '_ctypes' extension module now works when Python is configured
639 with the --without-threads option.
640
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000641- Bug #1513646: os.access on Windows now correctly determines write
642 access, again.
643
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000644- Bug #1512695: cPickle.loads could crash if it was interrupted with
645 a KeyboardInterrupt.
646
Neal Norwitza12aa882006-07-06 06:45:08 +0000647- Bug #1296433: parsing XML with a non-default encoding and
648 a CharacterDataHandler could crash the interpreter in pyexpat.
649
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000650- Patch #1516912: improve Modules support for OpenVMS.

654
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000655- Automate Windows build process for the Win64 SSL module.
656
Tim Peters32a83612006-07-10 21:08:24 +0000657- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000658 Previously, the slight difference could cause compilation errors of the
659 'zlib' module on systems with more than one version of zlib.
660
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000661- The MSI compileall step was fixed to also support a TARGETDIR
662 with spaces in it.
663
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000664- Bug #1517388: sqlite3.dll is now installed on Windows independent
665 of Tcl/Tk.
666
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000667- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000668 trying to be installed even though it's empty.

692Core and builtins
693-----------------
694
Georg Brandla56b9152006-06-19 06:35:54 +0000695- Patch #1507676: Error messages returned by invalid abstract object operations
696 (such as iterating over an integer) have been improved and now include the
697 type of the offending object to help with debugging.
698
Brett Cannonea3912b2006-06-13 21:46:41 +0000699- Bug #992017: A classic class that defined a __coerce__() method that returned
700 its arguments swapped would infinitely recurse and segfault the interpreter.
701
Neal Norwitz909eb122006-06-12 02:13:21 +0000702- Fix the socket tests so they can be run concurrently.
703
Neal Norwitzb9845e72006-06-12 02:11:18 +0000704- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000705 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000706
Brett Cannon22565aa2006-06-09 22:31:23 +0000707- Bug #532646: object.__call__() will continue looking for the __call__
708 attribute on objects until one without one is found. This leads to recursion
709 when you take a class and set its __call__ attribute to an instance of the
710 class. Originally fixed for classic classes, but this fix is for new-style.
711 Removes the infinite_rec_3 crasher.
712
Georg Brandl24250812006-06-09 18:45:48 +0000713- The string and unicode methods startswith() and endswith() now accept
714 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
715
Brett Cannonde3b0522006-06-08 17:00:45 +0000716- Buffer objects, at the C level, never used the char buffer
717 implementation even when the char buffer for the wrapped object was
718 explicitly requested (originally returned the read or write buffer).
719 Now a TypeError is raised if the char buffer is not present but is
720 requested.
721
Georg Brandlddbaa662006-06-04 21:56:52 +0000722- Patch #1346214: Statements like "if 0: suite" are now again optimized
723 away like they were in Python 2.4.
724
Georg Brandlb7c8f542006-05-27 12:30:25 +0000725- Builtin exceptions are now full-blown new-style classes instead of
726 instances pretending to be classes, which speeds up exception handling
727 by about 80% in comparison to 2.5a2.
728
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000729- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
730 Unicode 4.1.
731
Georg Brandlf4ef1162006-05-26 18:03:31 +0000732- Patch #921466: sys.path_importer_cache is now used to cache valid and
733 invalid file paths for the built-in import machinery which leads to
734 fewer open calls on startup.
735
Tim Peters696cf432006-05-24 21:10:40 +0000736- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
737 of-2 bases. The largest speedup is for inputs with about 1000 decimal
738 digits. Conversion from non-power-of-2 bases remains quadratic-time in
739 the number of input digits (it was and remains linear-time for bases
740 2, 4, 8, 16 and 32).
741
Tim Petersb713ec22006-05-23 18:45:30 +0000742- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
743 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
744 an integer close to ``sys.maxint``. This was repaired by patch
745 #1335972, which also gives a nice speedup.
746
Richard Jonescebbefc2006-05-23 18:28:17 +0000747- Patch #1337051: reduced size of frame objects.
748
749- PyErr_NewException now accepts a tuple of base classes as its
750 "base" parameter.
751
Richard Jones7c88dcc2006-05-23 10:37:38 +0000752- Patch #876206: function call speedup by retaining allocated frame
753 objects.
754
Georg Brandl7b90e162006-05-18 07:01:27 +0000755- Bug #1462152: file() now checks more thoroughly for invalid mode
756 strings and removes a possible "U" before passing the mode to the
757 C library function.
758
Neal Norwitz1004a532006-05-15 07:17:23 +0000759- Patch #1488312, Fix memory alignment problem on SPARC in unicode
760
Neal Norwitz373f0a72006-05-15 07:04:36 +0000761- Bug #1487966: Fix SystemError with conditional expression in assignment
762
Martin v. Löwis879768d2006-05-11 13:28:43 +0000763- WindowsError now has two error code attributes: errno, which carries
764 the error values from errno.h, and winerror, which carries the error
765 values from winerror.h. Previous versions put the winerror.h values
766 (from GetLastError()) into the errno attribute.
767
Martin v. Löwis77736712006-05-04 05:51:03 +0000768- Patch #1475845: Raise IndentationError for unexpected indent.
769
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000770- Patch #1479181: split open() and file() from being aliases for each other.
771
Tim Peters44bd9862006-06-01 13:49:23 +0000772- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
773 methods were always silently ignored by dictionaries when comparing keys.
774 They are now passed through (except when using the C API function
775 ``PyDict_GetItem()``, whose semantics did not change).
776
777- Bug #1456209: In some obscure cases it was possible for a class with a
778 custom ``__eq__()`` method to confuse dict internals when class instances
779 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
780 No, you don't have any code that did this ;-)

788
Brett Cannon6ee7d012006-06-08 16:23:04 +0000789- Change binascii.hexlify to accept a read-only buffer instead of only a char
790 buffer and actually follow its documentation.
791
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000792- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
793
Nick Coghlanc649ec52006-05-29 12:43:05 +0000794- Patch #1478788 (modified version): The functional extension module has
795 been renamed to _functools and a functools Python wrapper module added.
796 This provides a home for additional function related utilities that are
797 not specifically about functional programming. See PEP 309.
798
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000799- Patch #1493701: performance enhancements for struct module.
800
Georg Brandl378d5922006-05-17 14:26:50 +0000801- Patch #1490224: time.altzone is now set correctly on Cygwin.
802
Georg Brandl8d3342b2006-05-16 07:38:27 +0000803- Patch #1435422: zlib's compress and decompress objects now have a
804 copy() method.
805
Andrew MacIntyre92913322006-06-13 15:04:24 +0000806- Patch #1454481: thread stack size is now tunable at runtime for thread
807 enabled builds on Windows and systems with Posix threads support.
808
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000809- On Win32, os.listdir now supports arbitrarily-long Unicode path names
810 (up to the system limit of 32K characters).
811
812- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
813 As a result, these functions now raise WindowsError instead of OSError.
814
Tim Peters7a822da2006-05-25 21:50:17 +0000815- ``time.clock()`` on Win64 should use the high-performance Windows
816 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
817 Windows platforms).
818
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000819- Calling Tk_Init twice is refused if the first call failed as that
820 may deadlock.
821
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000822- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
823 accept it without potentially using an uninitialized pointer.
824
825- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
826 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
827 patch numbers 1494885 and 1494902]

Gregory P. Smith372b5832006-06-05 18:48:21 +0000829- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000830 [pybsddb project SF patch number 1466734]
831
Gregory P. Smith372b5832006-06-05 18:48:21 +0000832- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
833 parameter is supplied. [SF pybsddb bug #1477863]
834
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000835- bsddb: the __len__ method of a DB object has been fixed to return correct
836 results. It could previously incorrectly return 0 in some cases.
837 Fixes SF bug 1493322 (pybsddb bug 1184012).
838
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000839- bsddb: the bsddb.dbtables Modify method now raises the proper error and
840 aborts the db transaction safely when a modifier callback fails.
841 Fixes SF python patch/bug #1408584.
842
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000843- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000844 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000845 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
846 database calls that would previously deadlock. [SF python bug #775414]
847

870 mime.types file for determining MIME types.
871
Georg Brandl2605ca82006-06-14 06:08:31 +0000872- Bug #1339007: Shelf objects now don't raise an exception in their
873 __del__ method when initialization failed.
874
Martin v. Löwisd8251432006-06-14 05:21:04 +0000875- Patch #1455898: The MBCS codec now supports the incremental mode for
876 double-byte encodings.
877
Tim Peters43898b42006-06-14 04:09:25 +0000878- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
879 guarantee that adjacent triples in the return list always describe
880 non-adjacent blocks. Previously, a pair of matching blocks could end
881 up being described by multiple adjacent triples that formed a partition
882 of the matching pair.
883
Greg Ward0e0c9f42006-06-11 16:24:11 +0000884- Bug #1498146: fix optparse to handle Unicode strings in option help,
885 description, and epilog.
886
Greg Wardd1c797e2006-06-11 14:42:41 +0000887- Bug #1366250: minor optparse documentation error.

890 clarify docs.
891
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000892- The wsgiref package has been added to the standard library.
893
Nick Coghlan676725d2006-06-08 13:54:49 +0000894- The functions update_wrapper() and wraps() have been added to the functools
895 module. These make it easier to copy relevant metadata from the original
896 function when writing wrapper functions.
897
Tim Petersd6a9eef2006-06-05 01:48:21 +0000898- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
899 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000900
Martin v. Löwis3f767792006-06-04 19:36:28 +0000901- Patch #1359618: Speed up charmap encoder by using a trie structure
902 for lookup.
903
Tim Petersd609b1a2006-06-02 23:22:51 +0000904- The functions in the ``pprint`` module now sort dictionaries by key
905 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
906 if and only if its display required more than one line, although that
907 wasn't documented. The new behavior increases predictability; e.g.,

931 stdout arguments, making it possible to redirect input and output
932 for remote debugging.
933

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000980What's New in Python 2.5 alpha 2?
981=================================
982
983*Release date: 27-APR-2006*
984
985Core and builtins
986-----------------
987
Thomas Heller1b046642006-04-18 18:51:06 +0000988- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
989 by converting these apis from macros into exported functions again:
990
991 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
992 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
993 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
994 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
995 PyRun_String Py_CompileString
996
Martin v. Löwis45294a92006-04-18 06:24:08 +0000997- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
998
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000999- All uses of PyStructSequence_InitType have been changed to initialize
1000 the type objects only once, even if the interpreter is initialized
1001 multiple times.
1002
Neal Norwitz61546162006-04-14 05:20:28 +00001003- Bug #1454485, array.array('u') could crash the interpreter. This was
1004 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1005 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1006
1007- Py_UNICODE is unsigned. It was always documented as unsigned, but
1008 due to a bug had a signed value in previous versions.
1009
Tim Peters3a5e8b12006-04-11 01:44:07 +00001010- Patch #837242: ``id()`` of any Python object always gives a positive
1011 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1012 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001013 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001014 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001015
Tim Peters3a5e8b12006-04-11 01:44:07 +00001016 def __hash__(self):
1017 return id(self) # WRONG
1018
1019 because a hash result must be a (short) Python int but it was always
1020 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001021 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001022 was always usable as a hash value before this patch. That's no longer
1023 necessarily so.
1024
1025- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001026 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001027 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001028 #1454844)
1029
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001030- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1031 involving generators that have paused outside of any ``try`` or ``with``
1032 blocks. (In 2.5a1, a paused generator that was part of a reference
1033 cycle could not be garbage collected, regardless of whether it was
1034 paused in a ``try`` or ``with`` block.)

1043 fails with an error condition.
1044
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001045- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1046
1047- Bug #1117761: bsddb.*open() no longer raises an exception when using
1048 the cachesize parameter.
1049
1050- Bug #1149413: bsddb.*open() no longer raises an exception when using
1051 a temporary db (file=None) with the 'n' flag to truncate on open.
1052
1053- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1054 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001055
Armin Rigoa9017c32006-04-19 11:50:27 +00001056- Patch #1062014: AF_UNIX sockets under Linux have a special
1057 abstract namespace that is now fully supported.

1060-------
1061
Peter Astrand7d1d4362006-07-14 14:04:45 +00001062- Bug #1223937: subprocess.CalledProcessError reports the exit status
1063 of the process using the returncode attribute, instead of
1064 abusing errno.
1065
Tim Peters711bf302006-04-25 03:31:36 +00001066- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1067 a doctest to be skipped (the code is not run, and the expected output
1068 or exception is ignored).
1069
Nick Coghlanda2268f2006-04-24 04:37:15 +00001070- Fixed contextlib.nested to cope with exceptions being raised and
1071 caught inside exit handlers.
1072
Greg Wardab05edc2006-04-23 03:47:58 +00001073- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1074 hex, octal, or binary; add ``append_const`` action; keep going if
1075 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1076 added ``epilog`` for better help generation).
1077
Tim Peters21fbd572006-04-21 21:18:10 +00001078- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1079 called from a thread spawned as a side effect of importing a module.
1080
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001081- The pydoc module now supports documenting packages contained in
1082 .zip or .egg files.
1083
1084- The pkgutil module now has several new utility functions, such
1085 as ``walk_packages()`` to support working with packages that are either
1086 in the filesystem or zip files.
1087
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001088- The mailbox module can now modify and delete messages from
1089 mailboxes, in addition to simply reading them. Thanks to Gregory
1090 K. Johnson for writing the code, and to the 2005 Google Summer of
1091 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001092
Tim Petersc7605f22006-04-17 21:12:33 +00001093- The ``__del__`` method of class ``local`` in module ``_threading_local``
1094 returned before accomplishing any of its intended cleanup.
1095
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001096- Patch #790710: Add breakpoint command lists in pdb.
1097

Martin v. Löwis4b501e62006-04-15 08:41:11 +00001100- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1101
Anthony Baxtere29002c2006-04-12 12:07:31 +00001102- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1103 Windows. Bug #1469163.
1104
Phillip J. Eby47032112006-04-11 01:07:43 +00001105- The warnings, linecache, inspect, traceback, site, and doctest modules
1106 were updated to work correctly with modules imported from zipfiles or
1107 via other PEP 302 __loader__ objects.
1108
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001109- Patch #1467770: Reduce usage of subprocess._active to processes which
1110 the application hasn't waited on.
1111
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001112- Patch #1462222: Fix Tix.Grid.

1120-----
1121
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001122- The Makefile now has a reindent target, which runs reindent.py on
1123 the library.
1124
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001125- Patch #1470875: Building Python with MS Free Compiler
1126
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001127- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001128
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001129- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1130 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001131 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001132 CXX from --with-cxx-main, see description in README.
1133
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001134- Patch #1429775: Link extension modules with the shared libpython.
1135
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001136- Fixed a libffi build problem on MIPS systems.
1137
Tim Peters8931ff12006-05-13 23:28:20 +00001138- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1139 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1140 and "%zu" for unsigned integers of type ``size_t``.
1141
Anthony Baxter51bcb682006-04-05 14:51:42 +00001142Tests
1143-----
1144
Nick Coghlanda2268f2006-04-24 04:37:15 +00001145- test_contextlib now checks contextlib.nested can cope with exceptions
1146 being raised and caught inside exit handlers.
1147
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001148- test_cmd_line now checks operation of the -m and -c command switches
1149
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001150- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1151 it separately and by hand. It also wasn't cleaning up its changes to
1152 the current Decimal context.
1153
Thomas Woutersabd08882006-04-26 15:53:30 +00001154- regrtest.py now has a -M option to run tests that test the new limits of
1155 containers, on 64-bit architectures. Running these tests is only sensible
1156 on 64-bit machines with more than two gigabytes of memory. The argument
1157 passed is the maximum amount of memory for the tests to use.

Tim Petersb06d28c2006-05-12 01:57:59 +00001168- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1169
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001170- PEP 343: Added Context Types section to the library reference
1171 and attempted to bring other PEP 343 related documentation into
1172 line with the implementation and/or python-dev discussions.
1173
Tim Peters8dc73d22006-04-24 02:03:16 +00001174- Bug #1337990: clarified that ``doctest`` does not support examples
1175 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001178What's New in Python 2.5 alpha 1?
1179=================================
1180
Anthony Baxterebed3f62006-04-03 15:03:44 +00001181*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001182
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001183Core and builtins
1184-----------------
1185
Nick Coghlan43832302006-04-23 17:04:07 +00001186- PEP 338: -m command line switch now delegates to runpy.run_module
1187 allowing it to support modules in packages and zipfiles
1188
Martin v. Löwisc661b882006-04-20 04:54:23 +00001189- On Windows, .DLL is not an accepted file name extension for
1190 extension modules anymore; extensions are only found if they
1191 end in .PYD.
1192
Martin v. Löwisea62d252006-04-03 10:56:49 +00001193- Bug #1421664: sys.stderr.encoding is now set to the same value as
1194 sys.stdout.encoding.
1195
Neal Norwitz92e212f2006-04-03 04:48:37 +00001196- __import__ accepts keyword arguments.
1197
Georg Brandlccadf842006-03-31 18:54:53 +00001198- Patch #1460496: round() now accepts keyword arguments.
1199
Anthony Baxter262c00a2006-03-30 10:53:17 +00001200- Fixed bug #1459029 - unicode reprs were double-escaped.
1201
Hye-Shik Changd478f342006-03-23 12:32:36 +00001202- Patch #1396919: The system scope threads are reenabled on FreeBSD
1203 5.4 and later versions.
1204
Neal Norwitze98ccf62006-03-23 05:39:47 +00001205- Bug #1115379: Compiling a Unicode string with an encoding declaration
1206 now gives a SyntaxError.
1207
Georg Brandlabd1ff82006-03-18 07:59:59 +00001208- Previously, Python code had no easy way to access the contents of a
1209 cell object. Now, a ``cell_contents`` attribute has been added
1210 (closes patch #1170323).
1211
Tim Peterscf79aac2006-03-16 01:14:46 +00001212- Patch #1123430: Python's small-object allocator now returns an arena to
1213 the system ``free()`` when all memory within an arena becomes unused
1214 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1215 freed. Some applications will see a drop in virtual memory size now,
1216 especially long-running applications that, from time to time, temporarily
1217 use a large number of small objects. Note that when Python returns an
1218 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001219 platform C library will in turn return that memory to the operating system.
1220 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001221 appears to be effective at least on Microsoft C and gcc-based systems.
1222 Thanks to Evan Jones for hard work and patience.

Georg Brandl533ff6f2006-03-08 18:09:27 +00001224- Patch #1434038: property() now uses the getter's docstring if there is
1225 no "doc" argument given. This makes it possible to legitimately use
1226 property() as a decorator to produce a read-only property.
1227
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001228- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1229 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1230 of requiring an int or long in slicing and a few other contexts, enabling
1231 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1232
Neal Norwitz995acdf2006-03-07 05:01:00 +00001233- Fixed various bugs reported by Coverity's Prevent tool.
1234
Brett Cannonbf364092006-03-01 04:25:17 +00001235- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1236 new exception base class, BaseException, which has a new message attribute.
1237 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1238 Raising a string exception now raises a DeprecationWarning.
1239
Thomas Woutersfb609f42006-02-28 16:37:25 +00001240- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1241 explicitly relative, using 'from .module import name' to mean 'from the same
1242 package as this module is in. Imports without dots still default to the
1243 old relative-then-absolute, unless 'from __future__ import
1244 absolute_import' is used.
1245
Brett Cannona7446e32006-02-27 23:39:10 +00001246- Properly check if 'warnings' raises an exception (usually when a filter set
1247 to "error" is triggered) when raising a warning for raising string
1248 exceptions.
1249
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001250- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001251 The name was removed from Include/code.h.
1252
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001253- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001254
Guido van Rossum1968ad32006-02-25 22:38:04 +00001255- Patch 1433928:
1256 - The copy module now "copies" function objects (as atomic objects).
1257 - dict.__getitem__ now looks for a __missing__ hook before raising
1258 KeyError.
1259
Tim Peters84ef21c2006-02-28 20:39:06 +00001260- PEP 343: with statement implemented. Needs ``from __future__ import
1261 with_statement``. Use of 'with' as a variable will generate a warning.
1262 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001263 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001264 The following objects have __context__ methods:
1265 - The built-in file type.
1266 - The thread.LockType type.
1267 - The following types defined by the threading module:
1268 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1269 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001270
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001271- Fix the encodings package codec search function to only search
1272 inside its own package. Fixes problem reported in patch #1433198.
1273
1274 Note: Codec packages should implement and register their own
1275 codec search function. PEP 100 has the details.
1276
Tim Peters9ea89d22006-06-04 03:26:02 +00001277- PEP 353: Using ``Py_ssize_t`` as the index type.
1278
1279- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1280 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1281 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1282 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1283 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001284
Neal Norwitzfc76d632006-01-10 06:03:13 +00001285- Patch #1400181, fix unicode string formatting to not use the locale.
1286 This is how string objects work. u'%f' could use , instead of .
1287 for the decimal point. Now both strings and unicode always use periods.
1288
Neal Norwitz671b9e32006-01-09 07:07:12 +00001289- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1290 configure would break checking curses.h.
1291
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001292- Bug #959576: The pwd module is now builtin. This allows Python to be
1293 built on UNIX platforms without $HOME set.
1294
Neal Norwitzc10978f2005-12-19 06:07:16 +00001295- Bug #1072182, fix some potential problems if characters are signed.
1296
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001297- Bug #889500, fix line number on SyntaxWarning for global declarations.
1298
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001299- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1300
Neal Norwitze7214a12005-12-18 05:03:17 +00001301- Support for converting hex strings to floats no longer works.
1302 This was not portable. float('0x3') now raises a ValueError.
1303
Barry Warsaw2a38a862005-12-18 01:27:35 +00001304- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001305 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001306 is now displayed in interactive prompt banner.
1307
Georg Brandlfa166682005-12-17 21:45:17 +00001308- Implementation of PEP 341 - Unification of try/except and try/finally.
1309 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001310 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001311
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001312- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1313 now encodes backslash correctly.
1314
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001315- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1316
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001317- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001318 and long longs.
1319
Neal Norwitz67715f02005-11-09 06:59:35 +00001320- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001321 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001322 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001323
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001324- Replaced most Unicode charmap codecs with new ones using the
1325 new Unicode translate string feature in the builtin charmap
1326 codec; the codecs were created from the mapping tables available
1327 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1328 encodings now include a mapping for the Apple logo)
1329
Tim Peterse3547fd2005-12-16 23:13:57 +00001330- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001331
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001332- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001333
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001334- A new AST parser implementation was completed. The abstract
1335 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001336 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001337
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001338- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001339 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1340
Neal Norwitz708e51a2005-10-03 04:48:15 +00001341- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1342
Neal Norwitz11bd1192005-10-03 00:54:56 +00001343- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1344 Provide a warning when a directory is passed on the command line.
1345
Neal Norwitz40d37812005-10-02 01:48:49 +00001346- Fix segfault with invalid coding.
1347
1348- SF bug #772896: unknown encoding results in MemoryError.
1349
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001350- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001351 supported a __len__() method which evaluated to False when the iterator
1352 was empty.
1353
Guido van Rossum630db602005-09-20 18:49:54 +00001354- On 64-bit platforms, when __len__() returns a value that cannot be
1355 represented as a C int, raise OverflowError.
1356
Skip Montanarof8948ca2005-09-19 03:54:46 +00001357- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001358 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001359
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001360- SF bug #893549: parsing keyword arguments was broken with a few format
1361 codes.
1362
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001363- Changes donated by Elemental Security to make it work on AIX 5.3
1364 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1365 bug #105470: test_pwd fails on 64bit system (Opteron).
1366
Guido van Rossum539c6622005-09-14 17:49:54 +00001367- Changes donated by Elemental Security to make it work on HP-UX 11 on
1368 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1369
Georg Brandl4550b8d2005-08-26 06:43:52 +00001370- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001371 (fixes bug #1119418).
1372
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001373- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1374
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001375- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1376 exceptions that cause a function to exit.
1377
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001378- The implementation of set() and frozenset() was revised to use its
1379 own internal data structure. Memory consumption is reduced by 1/3
1380 and there are modest speed-ups as well. The API is unchanged.
1381
Tim Petersde7990b2005-07-17 23:45:23 +00001382- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1383
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001384- SF bug #1229429: PyObject_CallMethod failed to decrement some
1385 reference counts in some error exit cases.
1386
Tim Petersecc6e6a2005-07-10 22:30:55 +00001387- SF bug #1185883: Python's small-object memory allocator took over
1388 a block managed by the platform C library whenever a realloc specified
1389 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001390 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001391 portable way to copy data from the C-managed block into Python's
1392 small-object space without risking a memory fault. Python's small-object
1393 realloc now leaves such blocks under the control of the platform C
1394 realloc.
1395
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001396- SF bug #1232517: An overflow error was not detected properly when
1397 attempting to convert a large float to an int in os.utime().
1398
Raymond Hettinger3296e692005-06-29 23:29:56 +00001399- SF bug #1224347: hex longs now print with lowercase letters just
1400 like their int counterparts.
1401
Michael W. Hudson188d4362005-06-20 16:52:57 +00001402- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1403 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1404 interpreter states; back out that fix and do a better job (see
1405 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1406 for a longer write-up of the problem).
1407
Michael W. Hudsondf888462005-06-03 14:41:55 +00001408- SF patch #1180995: marshal now uses a binary format by default when
1409 serializing floats.
1410
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001411- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1412 the routines that promise to produce IEEE 754 binary representations
1413 of floats now simply copy bytes around.
1414
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001415- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1416 278.
1417
Brett Cannonc3647ac2005-04-26 03:45:26 +00001418- patch #1109424: int, long, float, complex, and unicode now check for the
1419 proper magic slot for type conversions when subclassed. Previously the
1420 magic slot was ignored during conversion. Semantics now match the way
1421 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001422 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001423 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001424 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001425
Barry Warsawc8d907c2005-04-19 23:43:40 +00001426- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1427 NULL, now raise an AttributeError when attempting to set or delete the
1428 attribute. Previously a TypeError was raised, but this was inconsistent
1429 with the equivalent pure-Python implementation.
1430
Michael W. Hudson774479c2005-04-18 08:46:17 +00001431- It is now safe to call PyGILState_Release() before
1432 PyEval_InitThreads() (note that if there is reason to believe there
1433 are multiple threads around you still must call PyEval_InitThreads()
1434 before using the Python API; this fix is for extension modules that
1435 have no way of knowing if Python is multi-threaded yet).
1436
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001437- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1438 disabled caused a crash.
1439
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001440- Bug #1165306: instancemethod_new allowed the creation of a method
1441 with im_class == im_self == NULL, which caused a crash when called.
1442
Tim Petersecc6e6a2005-07-10 22:30:55 +00001443- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001444 fixes the crash seen in bug #1165761
1445
Raymond Hettinger96229b12005-03-11 06:49:40 +00001446- Added two new builtins, any() and all().
1447
Brett Cannon409d8f22005-03-05 06:47:57 +00001448- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001449 (e.g., ``class C(): pass`` is no longer a syntax error).
1450 Patch #1176012 added support to the 'parser' module and 'compiler' package
1451 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001452
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001453- Patch #1115086: Support PY_LONGLONG in structmember.
1454
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001455- Bug #1155938: new style classes did not check that __init__() was
1456 returning None.
1457
Tim Petersecc6e6a2005-07-10 22:30:55 +00001458- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001459 ('\') with a specific error message.
1460
Martin v. Löwisff232d72005-03-03 09:24:38 +00001461- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1462
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001463- Bug #1124295: the __name__ attribute of file objects was
1464 inadvertently made inaccessible in restricted mode.
1465
Tim Petersecc6e6a2005-07-10 22:30:55 +00001466- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001467 an ferror() call.
1468
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001469- min() and max() now support key= arguments with the same meaning as in
1470 list.sort().
1471
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001472- The peephole optimizer now performs simple constant folding in expressions:
1473 (2+3) --> (5).
1474
Raymond Hettingera422c342005-01-11 03:03:27 +00001475- set and frozenset objects can now be marshalled. SF #1098985.
1476
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001477- Bug #1077106: Poor argument checking could cause memory corruption
1478 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001479
Jeremy Hyltonab630502005-02-04 18:44:06 +00001480- The parser did not complain about future statements in illegal
1481 positions. It once again reports a syntax error if a future
1482 statement occurs after anything other than a doc string.
1483
Neil Schemenauercf52c072005-08-12 17:34:58 +00001484- Change the %s format specifier for str objects so that it returns a
1485 unicode instance if the argument is not an instance of basestring and
1486 calling __str__ on the argument returns a unicode instance.
1487
Tim Petersf4e69282006-02-27 17:15:31 +00001488- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1489 current thread state when the auto-GIL-state machinery knows about
1490 it (since the thread state is being deleted, continuing to remember it
1491 can't help, but can hurt if another thread happens to get created with
1492 the same thread id).

1625 the request code argument, which results in more C-like behaviour
1626 for large or negative values.
1627
Tim Petersecc6e6a2005-07-10 22:30:55 +00001628- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

1643
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00001644- operator.itemgetter() and operator.attrgetter() now support retrieving

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001668- the cPickle module no longer accepts the deprecated None option in the
1669 args tuple returned by __reduce__().
1670
Raymond Hettingerb2594052004-12-05 09:25:51 +00001671- itertools.islice() now accepts None for the start and step arguments.
1672 This allows islice() to work more readily with slices:
1673 islice(s.start, s.stop, s.step)
1674
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001675- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001684- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1685 been renamed to have only a single underscore prefix. This was done to
1686 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001687
Nick Coghlan43832302006-04-23 17:04:07 +00001688- PEP 338: new module runpy defines a run_module function to support
1689 executing modules which provide access to source code or a code object
1690 via the PEP 302 import mechanisms.
1691
Anthony Baxter93f5b932006-04-03 08:05:07 +00001692- The email module's parsedate_tz function now sets the daylight savings

1700 in attribute values.
1701
Anthony Baxterc51ee692006-04-01 00:57:31 +00001702- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001703 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001704 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001705 module will not be built.
1706
Tim Petersc17976e2006-04-01 00:26:53 +00001707- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1708 aren't officially supported here, and trying to use them will probably
1709 raise an exception some day. But dicts have been allowed, and "mostly
1710 worked", so support for them won't go away without warning.
1711
Georg Brandl338ef7d2006-03-31 18:42:16 +00001712- Bug #1445068: getpass.getpass() can now be given an explicit stream
1713 argument to specify where to write the prompt.
1714
Georg Brandl22ec80b2006-03-31 18:25:44 +00001715- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1730
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001731- email 4.0 package now integrated. This is largely the same as the email 3.0
1732 package that was included in Python 2.3, except that PEP 8 module names are
1733 now used (e.g. mail.message instead of email.Message). The MIME classes
1734 have been moved to a subpackage (e.g. email.mime.text instead of
1735 email.MIMEText). The old names are still supported for now. Several
1736 deprecated Message methods have been removed and lots of bugs have been
1737 fixed. More details can be found in the email package documentation.
1738
Walter Dörwald40108c92006-03-27 08:15:44 +00001739- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1740 (a subclass of tuple) that provides incremental decoders and encoders
1741 (a way to use stateful codecs without the stream API). Python functions
1742 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1743 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1744 have been added.

1747 a ValueError instead of a StopIteration now (like file and cString.String do).

1828 "The consensus of researchers in this area (at least as
1829 expressed at the NIST Hash Function Workshop 10/31/05),
1830 is that SHA-256 is a good choice for the time being, but
1831 that research should continue, and other alternatives may
1832 arise from this research. The larger SHA's also seem OK."

Thomas Hellerd6c6e222005-01-20 19:20:16 +00002008- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2009
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002010- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2011
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002012- Enhancements to the csv module:
2013
2014 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002015 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002016 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002017 + Dialect parameter parsing has been re-implemented to improve error
2018 reporting.
2019 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2020 dictates.
2021 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002022 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002023 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002024 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2025 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002026 + reader now allows \r characters to be quoted (previously it only allowed
2027 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002028 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002029 + Dialect classes passed to the module are no longer instantiated by
2030 the module before being parsed (the former validation scheme required
2031 this, but the mechanism was unreliable).
2032 + The dialect registry now contains instances of the internal
2033 C-coded dialect type, rather than references to python objects.
2034 + the internal c-coded dialect type is now immutable.
2035 + register_dialect now accepts the same keyword dialect specifications
2036 as the reader and writer, allowing the user to register dialects
2037 without first creating a dialect class.
2038 + a configurable limit to the size of parsed fields has been added -
2039 previously, an unmatched quote character could result in the entire
2040 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002041 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002042 the parser field size limit (returning the former limit). The initial
2043 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002044 + A line_num attribute has been added to the reader object, which tracks
2045 the number of lines read from the source iterator. This is not
2046 the same as the number of records returned, as records can span
2047 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002048 + reader and writer objects were not being registered with the cyclic-GC.
2049 This has been fixed.
2050
Brett Cannone6539c42005-01-08 02:43:53 +00002051- _DummyThread objects in the threading module now delete self.__block that is
2052 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2053 lock primitives tend to be limited in number and thus should not be wasted on
2054 a _DummyThread object. Fixes bug #1089632.
2055
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002056- The imghdr module now detects Exif files.
2057
Raymond Hettinger6065d322004-12-20 23:51:53 +00002058- StringIO.truncate() now correctly adjusts the size attribute.
2059 (Bug #951915).
2060
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002061- locale.py now uses an updated locale alias table (built using
2062 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2063 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002064 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002065
Raymond Hettinger3557f422004-12-07 12:02:02 +00002066- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2067
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002068- the pickle module no longer accepts the deprecated None option in the
2069 args tuple returned by __reduce__().
2070
Brett Cannon84667c02004-12-07 03:25:18 +00002071- optparse now optionally imports gettext. This allows its use in setup.py.
2072
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002073- the pickle module no longer uses the deprecated bin parameter.
2074
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002075- the shelve module no longer uses the deprecated binary parameter.
2076
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002077- the pstats module no longer uses the deprecated ignore() method.
2078
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002079- the filecmp module no longer uses the deprecated use_statcache argument.
2080
Raymond Hettinger664347b2004-12-04 21:21:53 +00002081- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2082 extended or overridden by subclasses. Formerly, the subclassed method would
2083 be ignored by the rest of the module. (Bug #1078905).
2084
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002085- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002086 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002087
Walter Dörwald36733692004-12-22 12:50:50 +00002088- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2089 once when a size argument is given. This prevents a buffer overflow in the
2090 tokenizer with very long source lines.
2091
Barry Warsaw538561e2006-01-01 21:48:54 +00002092- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2093 immediately after creating the object, without any intervening
2094 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002095
Skip Montanaro05885812005-01-16 20:48:27 +00002096- The reconvert.quote function can now emit triple-quoted strings. The
2097 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002098
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002099- ``UserString.MutableString`` now supports negative indices in
2100 ``__setitem__`` and ``__delitem__``
2101
Greg Ward40407942005-03-05 02:53:17 +00002102- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2103 correctly.
2104
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002105- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2106 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2107 character even if the user has passed a size parameter to get a proper
2108 line ending. Remove the special handling of a "\r\n" that has been split
2109 between two lines.
2110
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002111- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2112 about illegal code points. The codec now supports PEP 293 style error
2113 handlers.
2114
Walter Dörwald78a78b02005-09-01 12:04:29 +00002115- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002116 from the input stream, so that the output is a byte string in the correct
2117 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002118
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002119- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2120 considering it exactly like a '*'.
2121
Walter Dörwald007f8df2005-10-09 19:42:27 +00002122- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2123 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002124
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002125- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2126
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002127- Patch #1413711: Certain patterns of differences were making difflib
2128 touch the recursion limit.
2129
Walter Dörwald58917a62006-03-31 15:26:22 +00002130- Bug #947906: An object oriented interface has been added to the calendar
2131 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002132 called as a script (e.g. via ``python -mcalendar``). Localized month and
2133 weekday names can be ouput (even if an exotic encoding is used) using
2134 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002135
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002136Build
2137-----
2138
Neal Norwitz602d3392006-03-31 08:21:40 +00002139- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2140 by using -mieee gcc option.
2141

2143
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002144- Build support for Win64-AMD64 was added.
2145
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002146- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2147
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002148- Patch #881820: look for openpty and forkpty also in libbsd.
2149
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002150- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2151 The zlib module is now builtin on Windows.
2152
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002153- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2154
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002155- Bug #1189330: configure did not correctly determine the necessary
2156 value of LINKCC if python was built with GCC 4.0.
2157
Trent Mick8321b422005-07-26 02:29:21 +00002158- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2159 vulnerability in zlib 1.2.1 and 1.2.2.
2160
Brett Cannon08cd5982005-04-24 22:26:38 +00002161- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2162 flags that change binary compatibility. Changes were also made to
2163 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002164 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002165
Bob Ippolitoed233462005-03-29 13:47:59 +00002166- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2167 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2168 no longer exists). This configure patch makes things right.
2169
Martin v. Löwise2713be2005-03-08 15:03:08 +00002170- Bug #1158607: Build with --disable-unicode again.
2171
Brett Cannon46d96232005-02-16 00:07:19 +00002172- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2173 defined. Discovered as a result of not being able to build on OS X.
2174
Brett Cannon516592f2004-12-07 00:42:59 +00002175- setup.py now uses the directories specified in LDFLAGS using the -L option
2176 and in CPPFLAGS using the -I option for adding library and include
2177 directories, respectively, for compiling extension modules against. This has
2178 led to the core being compiled using the values in CPPFLAGS. It also removes
2179 the need for the special-casing of both DarwinPorts and Fink for darwin since
2180 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2181 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2182 Fink, ``-I/opt/local/include`` for DarwinPorts).
2183
Brett Cannon43802422005-02-10 20:48:03 +00002184- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2185 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2186 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2187 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002189C API
2190-----
2191
Tim Petersc9d78aa2006-03-26 23:27:58 +00002192- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2193 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2194 is obtained via the ``PyObject_`` family, it must be released via the
2195 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2196 always been officially true, but when Python's small-object allocator was
2197 introduced, an attempt was made to cater to a few extension modules
2198 discovered at the time that obtained memory via ``PyObject_New`` but
2199 released it via ``PyMem_DEL``. It's years later, and if such code still
2200 exists it will fail now (probably with segfaults, but calling wrong
2201 low-level memory management functions can yield many symptoms).
2202
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002203- Added a C API for set and frozenset objects.
2204
Raymond Hettinger66517482004-12-03 11:45:13 +00002205- Removed PyRange_New().
2206
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002207- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2208 mapping argument now. This string is used as a mapping table. Byte values
2209 greater than the length of the string and 0xFFFE are treated as undefined
2210 mappings.
