17 use them).
18
Georg Brandla6b9ce12006-09-24 12:35:40 +000019- Fix a bug in the parser's future statement handling that led to "with"
20 not being recognized as a keyword after, e.g., this statement:
21 from __future__ import division, with_statement
22
Georg Brandlc57221e2006-09-25 07:04:10 +000023- Bug #1557232: fix seg fault with def f((((x)))) and def f(((x),)).

47
Georg Brandl1f215782006-09-24 10:36:08 +000048- Make webbrowser.BackgroundBrowser usable in Windows (it wasn't because

67-----------------
68
Neal Norwitz0bcafac2006-09-11 08:51:17 +000069- Make _PyGILState_NoteThreadState() static, it was not used anywhere
70 outside of pystate.c and should not be necessary.
71
Brett Cannon19d76c52006-09-09 07:18:44 +000072- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
73 allows calling unicode() on exceptions classes directly to succeed.
74
Georg Brandlecab6232006-09-06 06:47:02 +000075- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
76 Also make sure that every exception class has __module__ set to
77 'exceptions'.
78
Georg Brandl37a9e572006-09-06 06:09:34 +000079- Bug #1550983: emit better error messages for erroneous relative

81
Tim Peterscbdd3502006-09-05 01:47:53 +000082- Overflow checking code in integer division ran afoul of new gcc
83 optimizations. Changed to be more standard-conforming.

87
Neal Norwitzd3da7d32006-09-05 01:54:06 +000088- Patch #1546288: fix seg fault in dict_equal due to ref counting bug.
89
Neal Norwitz29a5fdb2006-09-05 02:21:38 +000090- The return tuple from str.rpartition(sep) is (tail, sep, head) where
91 head is the original string if sep was not found.
92
Neal Norwitz3b3aae02006-09-05 03:56:01 +000093- Bug #1520864: unpacking singleton tuples in list comprehensions and
94 generator expressions (x for x, in ... ) works again. Fixing this problem
95 required changing the .pyc magic number. This means that .pyc files
96 generated before 2.5c2 will be regenerated.

185Core and builtins
186-----------------
187
Neal Norwitz24b6f202006-09-05 04:43:56 +0000188- Fix infinite recursion when subclassing long and overriding __hash__.
189
190- Fix concatenation (+=) of long strings.
191
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000192- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000193 compared equal or unequal to a string and a UnicodeDecodeError
194 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000195
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000196 Instead, the equal (==) and unequal (!=) comparison operators will
197 now issue a UnicodeWarning and interpret the two objects as
198 unequal. The UnicodeWarning can be filtered as desired using
199 the warning framework, e.g. silenced completely, turned into an
200 exception, logged, etc.
201
202 Note that compare operators other than equal and unequal will still
203 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000204
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000205- Fix segfault when doing string formatting on subclasses of long.
206
207- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
208 with new-style classes.
209
210- Fix bug related to __len__ functions returning negative values with
211 classic classes.
212
213- Patch #1538606, Fix __index__() clipping. There were some problems
214 discovered with the API and how integers that didn't fit into Py_ssize_t
215 were handled. This patch attempts to provide enough alternatives
216 to effectively use __index__.
217
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000218- Bug #1536021: __hash__ may now return long int; the final hash
219 value is obtained by invoking hash on the long int.
220
Thomas Hellerab1049c2006-08-08 17:37:00 +0000221- Bug #1536786: buffer comparison could emit a RuntimeWarning.
222
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000223- Bug #1535165: fixed a segfault in input() and raw_input() when
224 sys.stdin is closed.
225
Thomas Heller74d36f02006-08-04 18:17:40 +0000226- On Windows, the PyErr_Warn function is now exported from
227 the Python dll again.
228
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000229- Bug #1191458: tracing over for loops now produces a line event
230 on each iteration. Fixing this problem required changing the .pyc
231 magic number. This means that .pyc files generated before 2.5c1
232 will be regenerated.
233
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000234- Bug #1333982: string/number constants were inappropriately stored
235 in the byte code and co_consts even if they were not used, ie
236 immediately popped off the stack.
237
Georg Brandle9462c72006-08-04 18:03:37 +0000238- Fixed a reference-counting problem in property().

241Library
242-------
243
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000244- Fix a bug in the ``compiler`` package that caused invalid code to be
245 generated for generator expressions.
246
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000247- The distutils version has been changed to 2.5.0. The change to
248 keep it programmatically in sync with the Python version running
249 the code (introduced in 2.5b3) has been reverted. It will continue
250 to be maintained manually as static string literal.
251
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000252- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000253 and this cannot be converted to the required C type, an exception is
254 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000255 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000256
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000257- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000258 an exception.
259
Tim Peterscbdd3502006-09-05 01:47:53 +0000260- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000261 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000262 workarounds for clocks with low resolution, to stop the code yielding
263 duplicate UUIDs.
264
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000265- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
266 before raising SystemExit, allowing IDLE to honor quit() and exit().
267
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000268- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
269
Georg Brandl7a1af772006-08-14 21:55:28 +0000270- Patch #1536071: trace.py should now find the full module name of a
271 file correctly even on Windows.
272
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000273- logging's atexit hook now runs even if the rest of the module has
274 already been cleaned up.
275
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000276- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000277
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000278- Bug #1531405, format_exception no longer raises an exception if
279 str(exception) raised an exception.
280
Neil Schemenauer06ded092006-08-04 16:20:30 +0000281- Fix a bug in the ``compiler`` package that caused invalid code to be
282 generated for nested functions.

293 raises the correct exceptions.
294
Thomas Heller1ce433e2006-08-14 16:20:04 +0000295- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
296 '-no-stack-protector' compiler flag for OpenBSD has been removed.
297
Thomas Heller86720042006-08-14 11:17:48 +0000298- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
299 uses the _as_parameter_ attribute when objects are passed to foreign
300 function calls. The ctypes version number was changed to 1.0.1.
301
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000302- Bug #1530559, struct.pack raises TypeError where it used to convert.
303 Passing float arguments to struct.pack when integers are expected
304 now triggers a DeprecationWarning.

331 code in OpenSSL.
332
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000333- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.
334
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000335- Bug #1530448, ctypes build failure on Solaris 10 was fixed.

Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000341- New API for Unicode rich comparisons: PyUnicode_RichCompare()
342
Tim Peters4643c2f2006-08-10 22:45:34 +0000343- Bug #1069160. Internal correctness changes were made to
344 ``PyThreadState_SetAsyncExc()``. A test case was added, and
345 the documentation was changed to state that the return value
346 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000349What's New in Python 2.5 beta 3?
350================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000351
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000352*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000353
354Core and builtins
355-----------------
356
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000357- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000358 returned a long (see PEP 353).
359
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000360- Bug #1515471: string.replace() accepts character buffers again.
361
Neal Norwitz07aadb12006-07-30 06:55:48 +0000362- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
363 This provides the proper warning for struct.pack().
364 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
365
Neal Norwitz0d62a062006-07-30 06:53:31 +0000366- Patch #1531113: Fix augmented assignment with yield expressions.
367 Also fix a SystemError when trying to assign to yield expressions.
368
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000369- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
370 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
371 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
372 excessive filesystem operations during imports.
373
Tim Petersbc24eee2006-07-27 01:14:53 +0000374- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
375 operations on signed longs that are formally undefined by C.
376 Unfortunately, at least one compiler now cares about that, so complicated
377 the code to make that compiler happy again.
378
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000379- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
380
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000381- Patch #1232023: Stop including current directory in search
382 path on Windows.
383
Neal Norwitze1fdb322006-07-21 05:32:28 +0000384- Fix some potential crashes found with failmalloc.
385
Neal Norwitze7563102006-07-17 01:00:16 +0000386- Fix warnings reported by Klocwork's static analysis tool.
387
Neal Norwitz84be93b2006-07-16 01:50:38 +0000388- Bug #1512814, Fix incorrect lineno's when code within a function
389 had more than 255 blank lines.
390
Georg Brandl9dceedb2006-07-12 15:31:17 +0000391- Patch #1521179: Python now accepts the standard options ``--help`` and
392 ``--version`` as well as ``/?`` on Windows.
393
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000394- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000395 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000396 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000397
Tim Peters112aad32006-07-19 00:03:19 +0000398- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000399 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000400 new ``sys._current_frames()`` returns a dictionary with one entry,
401 mapping the faux "thread id" 0 to the current frame.
402
Ronald Oussoren3075e162006-07-25 20:28:55 +0000403- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000404
Ronald Oussoren3075e162006-07-25 20:28:55 +0000405
Neal Norwitza1f10902006-07-12 07:28:29 +0000406Library
407-------
408
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000409- Correction of patch #1455898: In the mbcs decoder, set final=False
410 for stream decoder, but final=True for the decode function.
411
Georg Brandl07fec3a2006-08-01 18:49:24 +0000412- os.urandom no longer masks unrelated exceptions like SystemExit or
413 KeyboardInterrupt.
414
Tim Peters4643c2f2006-08-10 22:45:34 +0000415- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000416 shutil.copytree on Windows
417
Georg Brandle34ac7c2006-07-30 11:07:23 +0000418- Bug #1002398: The documentation for os.path.sameopenfile now correctly
419 refers to file descriptors, not file objects.
420
Tim Peterscbdd3502006-09-05 01:47:53 +0000421- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000422 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000423 #1513611, and probably others.
424
Georg Brandledd9b0d2006-07-29 09:33:26 +0000425- Bug #1441397: The compiler module now recognizes module and function
426 docstrings correctly as it did in Python 2.4.
427
Tim Peters6f681472006-07-27 23:44:37 +0000428- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
429 lost that tests are sorted by name before being run. This rarely
430 matters for well-written tests, but can create baffling symptoms if
431 side effects from one test to the next affect outcomes. ``DocTestFinder``
432 has been changed to sort the list of tests it returns.
433
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000434- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000435 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000436
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000437- Bug #978833: Really close underlying socket in _socketobject.close.
438
Georg Brandldb232dc2006-08-20 13:15:43 +0000439- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
440 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000441
Georg Brandlcf0c1722006-07-26 07:23:32 +0000442- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
443 to recursive calls and call it with the failing package name.
444
Martin v. Löwis0b483032006-07-25 09:53:12 +0000445- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
446
Georg Brandlc13c34c2006-07-24 14:09:56 +0000447- Patch #1515343: Fix printing of deprecated string exceptions with a
448 value in the traceback module.
449
Greg Ward48fae7a2006-07-23 16:05:51 +0000450- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
451
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000452- Patch #1524429: Use repr() instead of backticks in Tkinter again.
453
Brett Cannoncaebe222006-07-18 04:41:36 +0000454- Bug #1520914: Change time.strftime() to accept a zero for any position in its
455 argument tuple. For arguments where zero is illegal, the value is forced to
456 the minimum value that is correct. This is to support an undocumented but
457 common way people used to fill in inconsequential information in the time
458 tuple pre-2.4.
459
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000460- Patch #1220874: Update the binhex module for Mach-O.
461
Barry Warsawb110bad2006-07-21 14:51:07 +0000462- The email package has improved RFC 2231 support, specifically for
463 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
464 (name*0=<blah>) parameter continuations. This may change the types of
465 values returned from email.message.Message.get_param() and friends.
466 Specifically in some cases where non-encoded continuations were used,
467 get_param() used to return a 3-tuple of (None, None, string) whereas now it
468 will just return the string (since non-encoded continuations don't have
469 charset and language parts).
470
471 Also, whereas % values were decoded in all parameter continuations, they are
472 now only decoded in encoded parameter parts.
473
Ronald Oussoren3075e162006-07-25 20:28:55 +0000474- Bug #1517990: IDLE keybindings on MacOS X now work correctly
475
476- Bug #1517996: IDLE now longer shows the default Tk menu when a
477 path browser, class browser or debugger is the frontmost window on MacOS X
478
Barry Warsaw00decd72006-07-27 23:43:15 +0000479- Patch #1520294: Support for getset and member descriptors in types.py,
480 inspect.py, and pydoc.py. Specifically, this allows for querying the type
481 of an object against these built-in types and more importantly, for getting
482 their docstrings printed in the interactive interpreter's help() function.
483
Ronald Oussoren3075e162006-07-25 20:28:55 +0000484
Neal Norwitza1f10902006-07-12 07:28:29 +0000485Extension Modules
486-----------------
487
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000488- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
489 a socket operation on a socket with a timeout, the exception will be
490 caught correctly. Previously, the exception was not caught.
491
Thomas Heller1393d6a2006-07-28 21:43:20 +0000492- Patch #1529514: The _ctypes extension is now compiled on more
493 openbsd target platforms.
494
Tim Peters9cab5932006-07-28 00:30:00 +0000495- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
496 a memory leak, affecting pickles and deep copies.
497
Tim Petersbc24eee2006-07-27 01:14:53 +0000498- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000499 Paul Eggert.
500
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000501- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
502
Thomas Hellerce049a02006-07-14 17:51:14 +0000503- Patch #1521817: Index range checking on ctypes arrays containing
504 exactly one element enabled again. This allows iterating over these
505 arrays, without the need to check the array size before.
506
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000507- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000508 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000509 /dev/null in certain cases; this is now fixed.
510
Thomas Heller47d7a062006-07-12 08:43:47 +0000511- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
512 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000513
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000514- Because of a misspelled preprocessor symbol, ctypes was always
515 compiled without thread support; this is now fixed.
516
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000517- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
518 methods now allow their database parameter to be None as the
519 sleepycat API allows.
520
Matt Flemingec926502006-07-28 11:27:27 +0000521- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
522 bluetooth API compared with Linux and FreeBSD.
523
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000524Tests
525-----
526
527- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
528 how long the test file should take to play. Now accepts taking 2.93 secs
529 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
530
Georg Brandl4793aa32006-07-28 18:31:39 +0000531- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
532 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
533 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000534
Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000535Build
536-----
537
538- Bug #1439538: Drop usage of test -e in configure as it is not portable.
539
Ronald Oussoren26cad082006-08-01 21:00:57 +0000540Mac
541---
542
543- PythonLauncher now works correctly when the path to the script contains
544 characters that are treated specially by the shell (such as quotes).
545
546- Bug #1527397: PythonLauncher now launches scripts with the working directory
547 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000548 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000549 expect.

Georg Brandlad29e632006-06-21 17:45:17 +0000552What's New in Python 2.5 beta 2?

557Core and builtins
558-----------------
559
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000560- Bug #1441486: The literal representation of -(sys.maxint - 1)
561 again evaluates to a int object, not a long.
562
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000563- Bug #1501934: The scope of global variables that are locally assigned
564 using augmented assignment is now correctly determined.
565
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000566- Bug #927248: Recursive method-wrapper objects can now safely
567 be released.
568
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000569- Bug #1417699: Reject locale-specific decimal point in float()
570 and atof().
571
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000572- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
573 omit a default "error" argument for NULL pointer. This allows
574 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000575
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000576- Bug #1519018: 'as' is now validated properly in import statements.
577
Neal Norwitz28746ab2006-07-09 22:14:42 +0000578- On 64 bit systems, int literals that use less than 64 bits are
579 now ints rather than longs.
580
Neal Norwitzed657552006-07-10 00:04:44 +0000581- Bug #1512814, Fix incorrect lineno's when code at module scope
582 started after line 256.
583
Tim Peters32a83612006-07-10 21:08:24 +0000584- New function ``sys._current_frames()`` returns a dict mapping thread
585 id to topmost thread stack frame. This is for expert use, and is
586 especially useful for debugging application deadlocks. The functionality
587 was previously available in Fazal Majid's ``threadframe`` extension
588 module, but it wasn't possible to do this in a wholly threadsafe way from
589 an extension.

Georg Brandlad29e632006-06-21 17:45:17 +0000591Library
592-------
593
Martin v. Löwis77621582006-07-30 13:27:31 +0000594- Bug #1257728: Mention Cygwin in distutils error message about a missing
595 VS 2003.
596
Martin v. Löwis06c68b82006-07-10 22:11:28 +0000597- Patch #1519566: Update turtle demo, make begin_fill idempotent.
598
Tim Peters32a83612006-07-10 21:08:24 +0000599- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000600 environment variable to be set in order to the SDK environment
601 for finding the compiler, include files, etc.
602
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000603- Bug #1515998: Properly generate logical ids for files in bdist_msi.
604
Nick Coghlan2d792252006-07-06 13:47:18 +0000605- warnings.py now ignores ImportWarning by default
606
Thomas Woutersadd19112006-07-05 11:03:49 +0000607- string.Template() now correctly handles tuple-values. Previously,
608 multi-value tuples would raise an exception and single-value tuples would
609 be treated as the value they contain, instead.
610
Martin v. Löwisede77f52006-07-03 13:01:35 +0000611- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
612 even if some data are received.
613
Martin v. Löwis45482392006-07-03 12:28:58 +0000614- Bug #1267547: Put proper recursive setup.py call into the

624 is created.
625
Martin v. Löwis7596e832006-07-01 15:33:37 +0000626- Bug #1513223: .close() of a _socketobj now releases the underlying
627 socket again, which then gets closed as it becomes unreferenced.
628
Fred Drake10497c82006-06-29 02:57:48 +0000629- Bug #1504333: Make sgmllib support angle brackets in quoted
630 attribute values.

632- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
633 sgmllib ('[' and ']' were not accepted).
634
Georg Brandl1be63af2006-06-28 20:23:25 +0000635- Fix a bug in the turtle module's end_fill function.
636
Brett Cannon53ab5b72006-06-22 16:49:14 +0000637- Bug #1510580: The 'warnings' module improperly required that a Warning
638 category be either a types.ClassType and a subclass of Warning. The proper
639 check is just that it is a subclass with Warning as the documentation states.
640
Georg Brandlad29e632006-06-21 17:45:17 +0000641- The compiler module now correctly compiles the new try-except-finally
642 statement (bug #1509132).
643
Neal Norwitz60373cd2006-06-22 06:30:50 +0000644- The wsgiref package is now installed properly on Unix.
645
Vinay Sajip28e57612006-07-01 10:45:20 +0000646- A bug was fixed in logging.config.fileConfig() which caused a crash on
647 shutdown when fileConfig() was called multiple times.
648
Gerhard Häring762fbd32006-07-02 17:48:30 +0000649- The sqlite3 module did cut off data from the SQLite database at the first
650 null character before sending it to a custom converter. This has been fixed
651 now.

654-----------------
655
Tim Peters112aad32006-07-19 00:03:19 +0000656- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
657 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
658 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000659
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000660- Assigning None to pointer type fields in ctypes structures possible
661 overwrote the wrong fields, this is fixed now.
662
663- Fixed a segfault in _ctypes when ctypes.wintypes were imported
664 on non-Windows platforms.
665
666- Bug #1518190: The ctypes.c_void_p constructor now accepts any
667 integer or long, without range checking.
668
669- Patch #1517790: It is now possible to use custom objects in the ctypes
670 foreign function argtypes sequence as long as they provide a from_param
671 method, no longer is it required that the object is a ctypes type.
672
673- The '_ctypes' extension module now works when Python is configured
674 with the --without-threads option.
675
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000676- Bug #1513646: os.access on Windows now correctly determines write
677 access, again.
678
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000679- Bug #1512695: cPickle.loads could crash if it was interrupted with
680 a KeyboardInterrupt.
681
Neal Norwitza12aa882006-07-06 06:45:08 +0000682- Bug #1296433: parsing XML with a non-default encoding and
683 a CharacterDataHandler could crash the interpreter in pyexpat.

689
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000690- Automate Windows build process for the Win64 SSL module.
691
Tim Peters32a83612006-07-10 21:08:24 +0000692- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000693 Previously, the slight difference could cause compilation errors of the
694 'zlib' module on systems with more than one version of zlib.
695
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000696- The MSI compileall step was fixed to also support a TARGETDIR
697 with spaces in it.
698

700 of Tcl/Tk.
701
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000702- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old

727Core and builtins
728-----------------
729
Georg Brandla56b9152006-06-19 06:35:54 +0000730- Patch #1507676: Error messages returned by invalid abstract object operations
731 (such as iterating over an integer) have been improved and now include the
732 type of the offending object to help with debugging.
733
Brett Cannonea3912b2006-06-13 21:46:41 +0000734- Bug #992017: A classic class that defined a __coerce__() method that returned
735 its arguments swapped would infinitely recurse and segfault the interpreter.
736
Neal Norwitz909eb122006-06-12 02:13:21 +0000737- Fix the socket tests so they can be run concurrently.
738
Neal Norwitzb9845e72006-06-12 02:11:18 +0000739- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000740 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000741
Brett Cannon22565aa2006-06-09 22:31:23 +0000742- Bug #532646: object.__call__() will continue looking for the __call__
743 attribute on objects until one without one is found. This leads to recursion
744 when you take a class and set its __call__ attribute to an instance of the
745 class. Originally fixed for classic classes, but this fix is for new-style.
746 Removes the infinite_rec_3 crasher.
747
Georg Brandl24250812006-06-09 18:45:48 +0000748- The string and unicode methods startswith() and endswith() now accept
749 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
750
Brett Cannonde3b0522006-06-08 17:00:45 +0000751- Buffer objects, at the C level, never used the char buffer
752 implementation even when the char buffer for the wrapped object was
753 explicitly requested (originally returned the read or write buffer).
754 Now a TypeError is raised if the char buffer is not present but is
755 requested.
756
Georg Brandlddbaa662006-06-04 21:56:52 +0000757- Patch #1346214: Statements like "if 0: suite" are now again optimized
758 away like they were in Python 2.4.
759
Georg Brandlb7c8f542006-05-27 12:30:25 +0000760- Builtin exceptions are now full-blown new-style classes instead of
761 instances pretending to be classes, which speeds up exception handling
762 by about 80% in comparison to 2.5a2.
763
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000764- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
765 Unicode 4.1.
766
Georg Brandlf4ef1162006-05-26 18:03:31 +0000767- Patch #921466: sys.path_importer_cache is now used to cache valid and
768 invalid file paths for the built-in import machinery which leads to
769 fewer open calls on startup.
770
Tim Peters696cf432006-05-24 21:10:40 +0000771- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
772 of-2 bases. The largest speedup is for inputs with about 1000 decimal
773 digits. Conversion from non-power-of-2 bases remains quadratic-time in
774 the number of input digits (it was and remains linear-time for bases
775 2, 4, 8, 16 and 32).
776
Tim Petersb713ec22006-05-23 18:45:30 +0000777- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
778 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
779 an integer close to ``sys.maxint``. This was repaired by patch
780 #1335972, which also gives a nice speedup.
781
Richard Jonescebbefc2006-05-23 18:28:17 +0000782- Patch #1337051: reduced size of frame objects.
783
784- PyErr_NewException now accepts a tuple of base classes as its
785 "base" parameter.
786
Richard Jones7c88dcc2006-05-23 10:37:38 +0000787- Patch #876206: function call speedup by retaining allocated frame
788 objects.
789
Georg Brandl7b90e162006-05-18 07:01:27 +0000790- Bug #1462152: file() now checks more thoroughly for invalid mode
791 strings and removes a possible "U" before passing the mode to the
792 C library function.
793
Neal Norwitz1004a532006-05-15 07:17:23 +0000794- Patch #1488312, Fix memory alignment problem on SPARC in unicode
795
Neal Norwitz373f0a72006-05-15 07:04:36 +0000796- Bug #1487966: Fix SystemError with conditional expression in assignment
797
Martin v. Löwis879768d2006-05-11 13:28:43 +0000798- WindowsError now has two error code attributes: errno, which carries
799 the error values from errno.h, and winerror, which carries the error
800 values from winerror.h. Previous versions put the winerror.h values
801 (from GetLastError()) into the errno attribute.
802
Martin v. Löwis77736712006-05-04 05:51:03 +0000803- Patch #1475845: Raise IndentationError for unexpected indent.
804
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000805- Patch #1479181: split open() and file() from being aliases for each other.
806
Tim Peters44bd9862006-06-01 13:49:23 +0000807- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
808 methods were always silently ignored by dictionaries when comparing keys.
809 They are now passed through (except when using the C API function
810 ``PyDict_GetItem()``, whose semantics did not change).
811
812- Bug #1456209: In some obscure cases it was possible for a class with a
813 custom ``__eq__()`` method to confuse dict internals when class instances
814 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
815 No, you don't have any code that did this ;-)

823
Brett Cannon6ee7d012006-06-08 16:23:04 +0000824- Change binascii.hexlify to accept a read-only buffer instead of only a char
825 buffer and actually follow its documentation.
826
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000827- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
828
Nick Coghlanc649ec52006-05-29 12:43:05 +0000829- Patch #1478788 (modified version): The functional extension module has
830 been renamed to _functools and a functools Python wrapper module added.
831 This provides a home for additional function related utilities that are
832 not specifically about functional programming. See PEP 309.
833
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000834- Patch #1493701: performance enhancements for struct module.

842 enabled builds on Windows and systems with Posix threads support.
843
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000844- On Win32, os.listdir now supports arbitrarily-long Unicode path names
845 (up to the system limit of 32K characters).
846
847- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
848 As a result, these functions now raise WindowsError instead of OSError.
849
Tim Peters7a822da2006-05-25 21:50:17 +0000850- ``time.clock()`` on Win64 should use the high-performance Windows
851 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
852 Windows platforms).
853
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000854- Calling Tk_Init twice is refused if the first call failed as that
855 may deadlock.
856
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000857- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
858 accept it without potentially using an uninitialized pointer.
859
860- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
861 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

866
Gregory P. Smith372b5832006-06-05 18:48:21 +0000867- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
868 parameter is supplied. [SF pybsddb bug #1477863]
869
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000870- bsddb: the __len__ method of a DB object has been fixed to return correct
871 results. It could previously incorrectly return 0 in some cases.

873
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000874- bsddb: the bsddb.dbtables Modify method now raises the proper error and
875 aborts the db transaction safely when a modifier callback fails.
876 Fixes SF python patch/bug #1408584.
877
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000878- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000879 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000880 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
881 database calls that would previously deadlock. [SF python bug #775414]

911 double-byte encodings.
912
Tim Peters43898b42006-06-14 04:09:25 +0000913- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
914 guarantee that adjacent triples in the return list always describe
915 non-adjacent blocks. Previously, a pair of matching blocks could end
916 up being described by multiple adjacent triples that formed a partition
917 of the matching pair.
918

Greg Wardd1c797e2006-06-11 14:42:41 +0000922- Bug #1366250: minor optparse documentation error.
923
Greg Ward7f547402006-06-11 00:40:49 +0000924- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
925 clarify docs.
926
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000927- The wsgiref package has been added to the standard library.
928
Nick Coghlan676725d2006-06-08 13:54:49 +0000929- The functions update_wrapper() and wraps() have been added to the functools
930 module. These make it easier to copy relevant metadata from the original
931 function when writing wrapper functions.
932
Tim Petersd6a9eef2006-06-05 01:48:21 +0000933- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
934 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000935
Martin v. Löwis3f767792006-06-04 19:36:28 +0000936- Patch #1359618: Speed up charmap encoder by using a trie structure
937 for lookup.
938
Tim Petersd609b1a2006-06-02 23:22:51 +0000939- The functions in the ``pprint`` module now sort dictionaries by key
940 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
941 if and only if its display required more than one line, although that
942 wasn't documented. The new behavior increases predictability; e.g.,
943 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
944
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000945- Patch #1497027: try HTTP digest auth before basic auth in urllib2
946 (thanks for J. J. Lee).
947
Georg Brandl2b330372006-05-28 20:23:12 +0000948- Patch #1496206: improve urllib2 handling of passwords with respect to
949 default HTTP and HTTPS ports.
950
George Yoshidaf3c65de2006-05-28 16:39:09 +0000951- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
952
Bob Ippolito7298f272006-05-23 18:43:47 +0000953- Patch #1281707: speed up gzip.readline.
954
Georg Brandlb89316f2006-05-17 15:51:16 +0000955- Patch #1180296: Two new functions were added to the locale module:
956 format_string() to get the effect of "format % items" but locale-aware,
957 and currency() to format a monetary number with currency sign.
958
Georg Brandle3a25832006-05-17 14:56:04 +0000959- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
960 and several features added, such as speed and geometry control.
961
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000962- Patch #1488881: add support for external file objects in bz2 compressed
963 tarfiles.
964
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000965- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
966 stdout arguments, making it possible to redirect input and output
967 for remote debugging.
968
969- Patch #1484695: Update the tarfile module to version 0.8. This fixes
970 a couple of issues, notably handling of long file names using the
971 GNU LONGNAME extension.
972
973- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
974 new flag when ``name`` is already the name of an option flag.
975
976- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
977 package.
978
979- Patch #1472854: make the rlcompleter.Completer class usable on non-
980 UNIX platforms.
981
982- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
983
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000984- Bug #1472827: correctly escape newlines and tabs in attribute values in
985 the saxutils.XMLGenerator class.

Georg Brandl66a0dbb2006-06-08 12:54:13 +0000991- Bug #1502728: Correctly link against librt library on HP-UX.
992
Martin v. Löwis222c5152006-06-03 07:37:13 +0000993- OpenBSD 3.9 is supported now.
994
Martin v. Löwisa43190b2006-05-22 09:15:18 +0000995- Patch #1492356: Port to Windows CE.
996
Neal Norwitz58e28882006-05-19 07:00:58 +0000997- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.
998
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000999- Patch #1471883: Add --enable-universalsdk.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001015What's New in Python 2.5 alpha 2?
1016=================================
1017
1018*Release date: 27-APR-2006*
1019
1020Core and builtins
1021-----------------
1022
Thomas Heller1b046642006-04-18 18:51:06 +00001023- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1024 by converting these apis from macros into exported functions again:
1025
1026 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1027 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1028 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1029 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1030 PyRun_String Py_CompileString
1031
Martin v. Löwis45294a92006-04-18 06:24:08 +00001032- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1033
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001034- All uses of PyStructSequence_InitType have been changed to initialize
1035 the type objects only once, even if the interpreter is initialized
1036 multiple times.
1037
Neal Norwitz61546162006-04-14 05:20:28 +00001038- Bug #1454485, array.array('u') could crash the interpreter. This was
1039 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1040 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1041
1042- Py_UNICODE is unsigned. It was always documented as unsigned, but
1043 due to a bug had a signed value in previous versions.
1044
Tim Peters3a5e8b12006-04-11 01:44:07 +00001045- Patch #837242: ``id()`` of any Python object always gives a positive
1046 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1047 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001048 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001049 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001050
Tim Peters3a5e8b12006-04-11 01:44:07 +00001051 def __hash__(self):
1052 return id(self) # WRONG
1053
1054 because a hash result must be a (short) Python int but it was always
1055 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001056 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001057 was always usable as a hash value before this patch. That's no longer
1058 necessarily so.
1059
1060- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001061 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001062 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001063 #1454844)
1064
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001065- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1066 involving generators that have paused outside of any ``try`` or ``with``
1067 blocks. (In 2.5a1, a paused generator that was part of a reference
1068 cycle could not be garbage collected, regardless of whether it was
1069 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001070
Anthony Baxter51bcb682006-04-05 14:51:42 +00001071Extension Modules

1073
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001074- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1075 is a macro.
1076
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001077- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1078 fails with an error condition.
1079
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001080- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1081
1082- Bug #1117761: bsddb.*open() no longer raises an exception when using
1083 the cachesize parameter.
1084
1085- Bug #1149413: bsddb.*open() no longer raises an exception when using
1086 a temporary db (file=None) with the 'n' flag to truncate on open.
1087
1088- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1089 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001090
Armin Rigoa9017c32006-04-19 11:50:27 +00001091- Patch #1062014: AF_UNIX sockets under Linux have a special
1092 abstract namespace that is now fully supported.
1093

1095-------
1096
Peter Astrand7d1d4362006-07-14 14:04:45 +00001097- Bug #1223937: subprocess.CalledProcessError reports the exit status
1098 of the process using the returncode attribute, instead of
1099 abusing errno.
1100
Tim Peters711bf302006-04-25 03:31:36 +00001101- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1102 a doctest to be skipped (the code is not run, and the expected output
1103 or exception is ignored).
1104
Nick Coghlanda2268f2006-04-24 04:37:15 +00001105- Fixed contextlib.nested to cope with exceptions being raised and
1106 caught inside exit handlers.
1107
Greg Wardab05edc2006-04-23 03:47:58 +00001108- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1109 hex, octal, or binary; add ``append_const`` action; keep going if
1110 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1111 added ``epilog`` for better help generation).
1112
Tim Peters21fbd572006-04-21 21:18:10 +00001113- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1114 called from a thread spawned as a side effect of importing a module.
1115
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001116- The pydoc module now supports documenting packages contained in
1117 .zip or .egg files.
1118
1119- The pkgutil module now has several new utility functions, such
1120 as ``walk_packages()`` to support working with packages that are either
1121 in the filesystem or zip files.
1122
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001123- The mailbox module can now modify and delete messages from
1124 mailboxes, in addition to simply reading them. Thanks to Gregory
1125 K. Johnson for writing the code, and to the 2005 Google Summer of
1126 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001127
Tim Petersc7605f22006-04-17 21:12:33 +00001128- The ``__del__`` method of class ``local`` in module ``_threading_local``
1129 returned before accomplishing any of its intended cleanup.
1130
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001131- Patch #790710: Add breakpoint command lists in pdb.
1132
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001133- Patch #1063914: Add Tkinter.Misc.clipboard_get().

1136
Anthony Baxtere29002c2006-04-12 12:07:31 +00001137- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1138 Windows. Bug #1469163.
1139
Phillip J. Eby47032112006-04-11 01:07:43 +00001140- The warnings, linecache, inspect, traceback, site, and doctest modules
1141 were updated to work correctly with modules imported from zipfiles or
1142 via other PEP 302 __loader__ objects.
1143
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001144- Patch #1467770: Reduce usage of subprocess._active to processes which
1145 the application hasn't waited on.
1146

Skip Montanaro262fb922006-04-21 02:31:07 +00001151- The pstats.Stats class accepts an optional stream keyword argument to
1152 direct output to an alternate file-like object.
1153

Martin v. Löwis4be4e652006-04-17 19:25:49 +00001157- The Makefile now has a reindent target, which runs reindent.py on
1158 the library.
1159
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001160- Patch #1470875: Building Python with MS Free Compiler
1161
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001162- Patch #1161914: Add a python-config script.

Martin v. Löwis0f48d982006-04-14 14:34:26 +00001164- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1165 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001166 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001167 CXX from --with-cxx-main, see description in README.
1168
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001169- Patch #1429775: Link extension modules with the shared libpython.

Hye-Shik Changf4795c82006-04-26 19:20:26 +00001171- Fixed a libffi build problem on MIPS systems.
1172
Tim Peters8931ff12006-05-13 23:28:20 +00001173- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1174 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1175 and "%zu" for unsigned integers of type ``size_t``.
1176
Anthony Baxter51bcb682006-04-05 14:51:42 +00001177Tests
1178-----
1179
Nick Coghlanda2268f2006-04-24 04:37:15 +00001180- test_contextlib now checks contextlib.nested can cope with exceptions
1181 being raised and caught inside exit handlers.
1182
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001183- test_cmd_line now checks operation of the -m and -c command switches
1184
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001185- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1186 it separately and by hand. It also wasn't cleaning up its changes to
1187 the current Decimal context.
1188
Thomas Woutersabd08882006-04-26 15:53:30 +00001189- regrtest.py now has a -M option to run tests that test the new limits of
1190 containers, on 64-bit architectures. Running these tests is only sensible
1191 on 64-bit machines with more than two gigabytes of memory. The argument
1192 passed is the maximum amount of memory for the tests to use.

Nick Coghlanc195d8a2006-04-24 03:04:43 +00001205- PEP 343: Added Context Types section to the library reference
1206 and attempted to bring other PEP 343 related documentation into
1207 line with the implementation and/or python-dev discussions.
1208
Tim Peters8dc73d22006-04-24 02:03:16 +00001209- Bug #1337990: clarified that ``doctest`` does not support examples

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001218Core and builtins
1219-----------------
1220
Nick Coghlan43832302006-04-23 17:04:07 +00001221- PEP 338: -m command line switch now delegates to runpy.run_module

1223
Martin v. Löwisc661b882006-04-20 04:54:23 +00001224- On Windows, .DLL is not an accepted file name extension for
1225 extension modules anymore; extensions are only found if they
1226 end in .PYD.
1227
Martin v. Löwisea62d252006-04-03 10:56:49 +00001228- Bug #1421664: sys.stderr.encoding is now set to the same value as
1229 sys.stdout.encoding.
1230
Neal Norwitz92e212f2006-04-03 04:48:37 +00001231- __import__ accepts keyword arguments.

Anthony Baxter262c00a2006-03-30 10:53:17 +00001235- Fixed bug #1459029 - unicode reprs were double-escaped.
1236
Hye-Shik Changd478f342006-03-23 12:32:36 +00001237- Patch #1396919: The system scope threads are reenabled on FreeBSD
1238 5.4 and later versions.
1239
Neal Norwitze98ccf62006-03-23 05:39:47 +00001240- Bug #1115379: Compiling a Unicode string with an encoding declaration
1241 now gives a SyntaxError.
1242
Georg Brandlabd1ff82006-03-18 07:59:59 +00001243- Previously, Python code had no easy way to access the contents of a
1244 cell object. Now, a ``cell_contents`` attribute has been added
1245 (closes patch #1170323).
1246
Tim Peterscf79aac2006-03-16 01:14:46 +00001247- Patch #1123430: Python's small-object allocator now returns an arena to
1248 the system ``free()`` when all memory within an arena becomes unused
1249 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1250 freed. Some applications will see a drop in virtual memory size now,
1251 especially long-running applications that, from time to time, temporarily
1252 use a large number of small objects. Note that when Python returns an
1253 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001254 platform C library will in turn return that memory to the operating system.
1255 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001256 appears to be effective at least on Microsoft C and gcc-based systems.
1257 Thanks to Evan Jones for hard work and patience.
1258
Georg Brandl533ff6f2006-03-08 18:09:27 +00001259- Patch #1434038: property() now uses the getter's docstring if there is
1260 no "doc" argument given. This makes it possible to legitimately use
1261 property() as a decorator to produce a read-only property.
1262
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001263- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1264 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1265 of requiring an int or long in slicing and a few other contexts, enabling
1266 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1267
Neal Norwitz995acdf2006-03-07 05:01:00 +00001268- Fixed various bugs reported by Coverity's Prevent tool.
1269
Brett Cannonbf364092006-03-01 04:25:17 +00001270- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1271 new exception base class, BaseException, which has a new message attribute.
1272 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1273 Raising a string exception now raises a DeprecationWarning.
1274
Thomas Woutersfb609f42006-02-28 16:37:25 +00001275- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1276 explicitly relative, using 'from .module import name' to mean 'from the same
1277 package as this module is in. Imports without dots still default to the
1278 old relative-then-absolute, unless 'from __future__ import
1279 absolute_import' is used.
1280
Brett Cannona7446e32006-02-27 23:39:10 +00001281- Properly check if 'warnings' raises an exception (usually when a filter set
1282 to "error" is triggered) when raising a warning for raising string
1283 exceptions.
1284
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001285- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001286 The name was removed from Include/code.h.
1287
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001288- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001289
Guido van Rossum1968ad32006-02-25 22:38:04 +00001290- Patch 1433928:
1291 - The copy module now "copies" function objects (as atomic objects).
1292 - dict.__getitem__ now looks for a __missing__ hook before raising
1293 KeyError.
1294
Tim Peters84ef21c2006-02-28 20:39:06 +00001295- PEP 343: with statement implemented. Needs ``from __future__ import
1296 with_statement``. Use of 'with' as a variable will generate a warning.
1297 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001298 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001299 The following objects have __context__ methods:
1300 - The built-in file type.
1301 - The thread.LockType type.
1302 - The following types defined by the threading module:
1303 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1304 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001305
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001306- Fix the encodings package codec search function to only search
1307 inside its own package. Fixes problem reported in patch #1433198.
1308
1309 Note: Codec packages should implement and register their own
1310 codec search function. PEP 100 has the details.
1311
Tim Peters9ea89d22006-06-04 03:26:02 +00001312- PEP 353: Using ``Py_ssize_t`` as the index type.
1313
1314- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1315 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1316 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1317 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1318 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001319
Neal Norwitzfc76d632006-01-10 06:03:13 +00001320- Patch #1400181, fix unicode string formatting to not use the locale.
1321 This is how string objects work. u'%f' could use , instead of .
1322 for the decimal point. Now both strings and unicode always use periods.
1323
Neal Norwitz671b9e32006-01-09 07:07:12 +00001324- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1325 configure would break checking curses.h.
1326
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001327- Bug #959576: The pwd module is now builtin. This allows Python to be
1328 built on UNIX platforms without $HOME set.
1329
Neal Norwitzc10978f2005-12-19 06:07:16 +00001330- Bug #1072182, fix some potential problems if characters are signed.
1331
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001332- Bug #889500, fix line number on SyntaxWarning for global declarations.
1333
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001334- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1335
Neal Norwitze7214a12005-12-18 05:03:17 +00001336- Support for converting hex strings to floats no longer works.
1337 This was not portable. float('0x3') now raises a ValueError.
1338
Barry Warsaw2a38a862005-12-18 01:27:35 +00001339- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001340 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001341 is now displayed in interactive prompt banner.
1342
Georg Brandlfa166682005-12-17 21:45:17 +00001343- Implementation of PEP 341 - Unification of try/except and try/finally.
1344 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001345 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001346
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001347- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1348 now encodes backslash correctly.
1349
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001350- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1351
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001352- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001353 and long longs.
1354
Neal Norwitz67715f02005-11-09 06:59:35 +00001355- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001356 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001357 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001358
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001359- Replaced most Unicode charmap codecs with new ones using the
1360 new Unicode translate string feature in the builtin charmap
1361 codec; the codecs were created from the mapping tables available
1362 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1363 encodings now include a mapping for the Apple logo)
1364
Tim Peterse3547fd2005-12-16 23:13:57 +00001365- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001366
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001367- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001368
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001369- A new AST parser implementation was completed. The abstract
1370 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001371 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001372
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001373- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001374 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1375
Neal Norwitz708e51a2005-10-03 04:48:15 +00001376- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1377
Neal Norwitz11bd1192005-10-03 00:54:56 +00001378- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1379 Provide a warning when a directory is passed on the command line.
1380
Neal Norwitz40d37812005-10-02 01:48:49 +00001381- Fix segfault with invalid coding.
1382
1383- SF bug #772896: unknown encoding results in MemoryError.
1384
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001385- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001386 supported a __len__() method which evaluated to False when the iterator
1387 was empty.
1388
Guido van Rossum630db602005-09-20 18:49:54 +00001389- On 64-bit platforms, when __len__() returns a value that cannot be
1390 represented as a C int, raise OverflowError.
1391
Skip Montanarof8948ca2005-09-19 03:54:46 +00001392- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001393 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001394
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001395- SF bug #893549: parsing keyword arguments was broken with a few format
1396 codes.
1397
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001398- Changes donated by Elemental Security to make it work on AIX 5.3
1399 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1400 bug #105470: test_pwd fails on 64bit system (Opteron).
1401
Guido van Rossum539c6622005-09-14 17:49:54 +00001402- Changes donated by Elemental Security to make it work on HP-UX 11 on
1403 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1404
Georg Brandl4550b8d2005-08-26 06:43:52 +00001405- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001406 (fixes bug #1119418).
1407
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001408- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1409
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001410- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1411 exceptions that cause a function to exit.
1412
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001413- The implementation of set() and frozenset() was revised to use its
1414 own internal data structure. Memory consumption is reduced by 1/3
1415 and there are modest speed-ups as well. The API is unchanged.
1416
Tim Petersde7990b2005-07-17 23:45:23 +00001417- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1418
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001419- SF bug #1229429: PyObject_CallMethod failed to decrement some
1420 reference counts in some error exit cases.
1421
Tim Petersecc6e6a2005-07-10 22:30:55 +00001422- SF bug #1185883: Python's small-object memory allocator took over
1423 a block managed by the platform C library whenever a realloc specified
1424 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001425 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001426 portable way to copy data from the C-managed block into Python's
1427 small-object space without risking a memory fault. Python's small-object
1428 realloc now leaves such blocks under the control of the platform C
1429 realloc.
1430
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001431- SF bug #1232517: An overflow error was not detected properly when
1432 attempting to convert a large float to an int in os.utime().
1433
Raymond Hettinger3296e692005-06-29 23:29:56 +00001434- SF bug #1224347: hex longs now print with lowercase letters just
1435 like their int counterparts.
1436
Michael W. Hudson188d4362005-06-20 16:52:57 +00001437- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1438 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1439 interpreter states; back out that fix and do a better job (see
1440 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1441 for a longer write-up of the problem).
1442
Michael W. Hudsondf888462005-06-03 14:41:55 +00001443- SF patch #1180995: marshal now uses a binary format by default when
1444 serializing floats.
1445
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001446- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1447 the routines that promise to produce IEEE 754 binary representations
1448 of floats now simply copy bytes around.
1449
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001450- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1451 278.
1452
Brett Cannonc3647ac2005-04-26 03:45:26 +00001453- patch #1109424: int, long, float, complex, and unicode now check for the
1454 proper magic slot for type conversions when subclassed. Previously the
1455 magic slot was ignored during conversion. Semantics now match the way
1456 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001457 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001458 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001459 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001460
Barry Warsawc8d907c2005-04-19 23:43:40 +00001461- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1462 NULL, now raise an AttributeError when attempting to set or delete the
1463 attribute. Previously a TypeError was raised, but this was inconsistent
1464 with the equivalent pure-Python implementation.
1465
Michael W. Hudson774479c2005-04-18 08:46:17 +00001466- It is now safe to call PyGILState_Release() before
1467 PyEval_InitThreads() (note that if there is reason to believe there
1468 are multiple threads around you still must call PyEval_InitThreads()
1469 before using the Python API; this fix is for extension modules that
1470 have no way of knowing if Python is multi-threaded yet).
1471
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001472- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1473 disabled caused a crash.
1474
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001475- Bug #1165306: instancemethod_new allowed the creation of a method
1476 with im_class == im_self == NULL, which caused a crash when called.
1477
Tim Petersecc6e6a2005-07-10 22:30:55 +00001478- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001479 fixes the crash seen in bug #1165761
1480
Raymond Hettinger96229b12005-03-11 06:49:40 +00001481- Added two new builtins, any() and all().
1482
Brett Cannon409d8f22005-03-05 06:47:57 +00001483- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001484 (e.g., ``class C(): pass`` is no longer a syntax error).
1485 Patch #1176012 added support to the 'parser' module and 'compiler' package
1486 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001487
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001488- Patch #1115086: Support PY_LONGLONG in structmember.
1489
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001490- Bug #1155938: new style classes did not check that __init__() was
1491 returning None.
1492
Tim Petersecc6e6a2005-07-10 22:30:55 +00001493- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001494 ('\') with a specific error message.
1495

1520 unicode instance if the argument is not an instance of basestring and
1521 calling __str__ on the argument returns a unicode instance.
1522
Tim Petersf4e69282006-02-27 17:15:31 +00001523- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1524 current thread state when the auto-GIL-state machinery knows about
1525 it (since the thread state is being deleted, continuing to remember it
1526 can't help, but can hurt if another thread happens to get created with
1527 the same thread id).

1735 in attribute values.
1736
Anthony Baxterc51ee692006-04-01 00:57:31 +00001737- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001738 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001739 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001740 module will not be built.

Tim Petersc17976e2006-04-01 00:26:53 +00001742- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1743 aren't officially supported here, and trying to use them will probably

1765
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001766- email 4.0 package now integrated. This is largely the same as the email 3.0
1767 package that was included in Python 2.3, except that PEP 8 module names are
1768 now used (e.g. mail.message instead of email.Message). The MIME classes
1769 have been moved to a subpackage (e.g. email.mime.text instead of
1770 email.MIMEText). The old names are still supported for now. Several
1771 deprecated Message methods have been removed and lots of bugs have been
1772 fixed. More details can be found in the email package documentation.

1775 (a subclass of tuple) that provides incremental decoders and encoders
1776 (a way to use stateful codecs without the stream API). Python functions
1777 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1778 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1779 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001780
Walter Dörwald067db482006-03-15 22:17:27 +00001781- Patch #1359365: Calling next() on a closed StringIO.String object raises
1782 a ValueError instead of a StopIteration now (like file and cString.String do).
1783 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1784 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00001858 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1859 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1860 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1861 Ronald L. Rivest offered this advice for Python:
1862
1863 "The consensus of researchers in this area (at least as
1864 expressed at the NIST Hash Function Workshop 10/31/05),
1865 is that SHA-256 is a good choice for the time being, but
1866 that research should continue, and other alternatives may
1867 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001868

Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002024- Patch #1049151: xdrlib now unpacks booleans as True or False.
2025
Raymond Hettingerbab41432005-02-05 01:31:19 +00002026- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2027
Guido van Rossumd0641422005-02-03 15:01:24 +00002028- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2029 disables recursive traversal through instance attributes, which can
2030 be exploited in various ways.
2031
Tim Peterse3547fd2005-12-16 23:13:57 +00002032- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002033 flags on the HTTP listening socket.
2034
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002035- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2036 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2037
Fred Drakefbdeaad2006-07-29 16:56:15 +00002038- Patches #893642, #1039083: add allow_none, encoding arguments to
2039 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002040

2042
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002043- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2044
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002045- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2046
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002047- Enhancements to the csv module:
2048
2049 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002050 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002051 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002052 + Dialect parameter parsing has been re-implemented to improve error
2053 reporting.
2054 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2055 dictates.
2056 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002057 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002058 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002059 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2060 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002061 + reader now allows \r characters to be quoted (previously it only allowed
2062 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002063 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002064 + Dialect classes passed to the module are no longer instantiated by
2065 the module before being parsed (the former validation scheme required
2066 this, but the mechanism was unreliable).
2067 + The dialect registry now contains instances of the internal
2068 C-coded dialect type, rather than references to python objects.
2069 + the internal c-coded dialect type is now immutable.
2070 + register_dialect now accepts the same keyword dialect specifications
2071 as the reader and writer, allowing the user to register dialects
2072 without first creating a dialect class.
2073 + a configurable limit to the size of parsed fields has been added -
2074 previously, an unmatched quote character could result in the entire
2075 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002076 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002077 the parser field size limit (returning the former limit). The initial
2078 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002079 + A line_num attribute has been added to the reader object, which tracks
2080 the number of lines read from the source iterator. This is not
2081 the same as the number of records returned, as records can span
2082 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002083 + reader and writer objects were not being registered with the cyclic-GC.
2084 This has been fixed.
2085
Brett Cannone6539c42005-01-08 02:43:53 +00002086- _DummyThread objects in the threading module now delete self.__block that is
2087 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2088 lock primitives tend to be limited in number and thus should not be wasted on
2089 a _DummyThread object. Fixes bug #1089632.
2090
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002091- The imghdr module now detects Exif files.
2092
Raymond Hettinger6065d322004-12-20 23:51:53 +00002093- StringIO.truncate() now correctly adjusts the size attribute.
2094 (Bug #951915).
2095
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002096- locale.py now uses an updated locale alias table (built using
2097 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2098 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002099 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002100
Raymond Hettinger3557f422004-12-07 12:02:02 +00002101- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2102
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002103- the pickle module no longer accepts the deprecated None option in the
2104 args tuple returned by __reduce__().
2105
Brett Cannon84667c02004-12-07 03:25:18 +00002106- optparse now optionally imports gettext. This allows its use in setup.py.
2107
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002108- the pickle module no longer uses the deprecated bin parameter.
2109
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002110- the shelve module no longer uses the deprecated binary parameter.
2111
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002112- the pstats module no longer uses the deprecated ignore() method.
2113
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002114- the filecmp module no longer uses the deprecated use_statcache argument.
2115
Raymond Hettinger664347b2004-12-04 21:21:53 +00002116- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2117 extended or overridden by subclasses. Formerly, the subclassed method would
2118 be ignored by the rest of the module. (Bug #1078905).
2119
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002120- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002121 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002122
Walter Dörwald36733692004-12-22 12:50:50 +00002123- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2124 once when a size argument is given. This prevents a buffer overflow in the
2125 tokenizer with very long source lines.
2126
Barry Warsaw538561e2006-01-01 21:48:54 +00002127- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2128 immediately after creating the object, without any intervening
2129 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002130
Skip Montanaro05885812005-01-16 20:48:27 +00002131- The reconvert.quote function can now emit triple-quoted strings. The
2132 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002133
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002134- ``UserString.MutableString`` now supports negative indices in
2135 ``__setitem__`` and ``__delitem__``
2136
Greg Ward40407942005-03-05 02:53:17 +00002137- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2138 correctly.
2139
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002140- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2141 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2142 character even if the user has passed a size parameter to get a proper
2143 line ending. Remove the special handling of a "\r\n" that has been split
2144 between two lines.
2145
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002146- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2147 about illegal code points. The codec now supports PEP 293 style error
2148 handlers.
2149
Walter Dörwald78a78b02005-09-01 12:04:29 +00002150- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002151 from the input stream, so that the output is a byte string in the correct
2152 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002153
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002154- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2155 considering it exactly like a '*'.
2156
Walter Dörwald007f8df2005-10-09 19:42:27 +00002157- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2158 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002159
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002160- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2161
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002162- Patch #1413711: Certain patterns of differences were making difflib
2163 touch the recursion limit.
2164
Walter Dörwald58917a62006-03-31 15:26:22 +00002165- Bug #947906: An object oriented interface has been added to the calendar
2166 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002167 called as a script (e.g. via ``python -mcalendar``). Localized month and
2168 weekday names can be ouput (even if an exotic encoding is used) using
2169 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002170
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002171Build
2172-----
2173
Neal Norwitz602d3392006-03-31 08:21:40 +00002174- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2175 by using -mieee gcc option.
2176

2178
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002179- Build support for Win64-AMD64 was added.
2180
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002181- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2182
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002183- Patch #881820: look for openpty and forkpty also in libbsd.
2184
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002185- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2186 The zlib module is now builtin on Windows.
2187
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002188- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2189
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002190- Bug #1189330: configure did not correctly determine the necessary
2191 value of LINKCC if python was built with GCC 4.0.
2192
Trent Mick8321b422005-07-26 02:29:21 +00002193- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2194 vulnerability in zlib 1.2.1 and 1.2.2.
2195
Brett Cannon08cd5982005-04-24 22:26:38 +00002196- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2197 flags that change binary compatibility. Changes were also made to
2198 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002199 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002200
Bob Ippolitoed233462005-03-29 13:47:59 +00002201- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2202 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2203 no longer exists). This configure patch makes things right.
2204
Martin v. Löwise2713be2005-03-08 15:03:08 +00002205- Bug #1158607: Build with --disable-unicode again.
2206
Brett Cannon46d96232005-02-16 00:07:19 +00002207- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2208 defined. Discovered as a result of not being able to build on OS X.
2209
Brett Cannon516592f2004-12-07 00:42:59 +00002210- setup.py now uses the directories specified in LDFLAGS using the -L option
2211 and in CPPFLAGS using the -I option for adding library and include
2212 directories, respectively, for compiling extension modules against. This has
2213 led to the core being compiled using the values in CPPFLAGS. It also removes
2214 the need for the special-casing of both DarwinPorts and Fink for darwin since
2215 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2216 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2217 Fink, ``-I/opt/local/include`` for DarwinPorts).
2218
Brett Cannon43802422005-02-10 20:48:03 +00002219- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2220 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2221 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2222 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002224C API
2225-----
2226
Tim Petersc9d78aa2006-03-26 23:27:58 +00002227- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2228 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2229 is obtained via the ``PyObject_`` family, it must be released via the
2230 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2231 always been officially true, but when Python's small-object allocator was
2232 introduced, an attempt was made to cater to a few extension modules
2233 discovered at the time that obtained memory via ``PyObject_New`` but
2234 released it via ``PyMem_DEL``. It's years later, and if such code still
2235 exists it will fail now (probably with segfaults, but calling wrong
2236 low-level memory management functions can yield many symptoms).
2237
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002238- Added a C API for set and frozenset objects.
2239
Raymond Hettinger66517482004-12-03 11:45:13 +00002240- Removed PyRange_New().
2241
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002242- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2243 mapping argument now. This string is used as a mapping table. Byte values
2244 greater than the length of the string and 0xFFFE are treated as undefined
2245 mappings.
