Neal Norwitza1f10902006-07-12 07:28:29 +00007What's New in Python 2.5 release candidate 1?
8=============================================
9
10*Release date: XX-AUG-2006*
11
12Core and builtins
13-----------------
14
Tim Petersbc24eee2006-07-27 01:14:53 +000015- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
16 operations on signed longs that are formally undefined by C.
17 Unfortunately, at least one compiler now cares about that, so complicated
18 the code to make that compiler happy again.
19
Martin v. Löwis982e9fe2006-07-24 12:54:17 +000020- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
21
Martin v. Löwisd22968a2006-07-24 11:54:53 +000022- Patch #1232023: Stop including current directory in search
23 path on Windows.
24
Neal Norwitze1fdb322006-07-21 05:32:28 +000025- Fix some potential crashes found with failmalloc.
26
Neal Norwitze7563102006-07-17 01:00:16 +000027- Fix warnings reported by Klocwork's static analysis tool.
28
Neal Norwitz84be93b2006-07-16 01:50:38 +000029- Bug #1512814, Fix incorrect lineno's when code within a function
30 had more than 255 blank lines.
31
Georg Brandl9dceedb2006-07-12 15:31:17 +000032- Patch #1521179: Python now accepts the standard options ``--help`` and
33 ``--version`` as well as ``/?`` on Windows.
34
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +000035- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +000036 again. Fixing this problem required changing the .pyc magic number.
37 This means that .pyc files generated before 2.5c1 will be regenerated.
38
Tim Peters112aad32006-07-19 00:03:19 +000039- Bug #1524317: Compiling Python ``--without-threads`` failed.
40 The Python core compiles again then, and, in a build without threads, the
41 new ``sys._current_frames()`` returns a dictionary with one entry,
42 mapping the faux "thread id" 0 to the current frame.
43
Ronald Oussoren3075e162006-07-25 20:28:55 +000044- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +000045
Ronald Oussoren3075e162006-07-25 20:28:55 +000046

48-------
49
Tim Peters6f681472006-07-27 23:44:37 +000050- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
51 lost that tests are sorted by name before being run. This rarely
52 matters for well-written tests, but can create baffling symptoms if
53 side effects from one test to the next affect outcomes. ``DocTestFinder``
54 has been changed to sort the list of tests it returns.
55
Martin v. Löwis997ceff2006-07-27 06:38:16 +000056- The distutils version has been changed to 2.5.0.
57
Martin v. Löwis9298eff2006-07-26 12:12:56 +000058- Bug #978833: Really close underlying socket in _socketobject.close.
59
Georg Brandl0619a322006-07-26 07:40:17 +000060- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
61 with title().
62
Georg Brandlcf0c1722006-07-26 07:23:32 +000063- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
64 to recursive calls and call it with the failing package name.
65
Martin v. Löwis0b483032006-07-25 09:53:12 +000066- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
67
Georg Brandlc13c34c2006-07-24 14:09:56 +000068- Patch #1515343: Fix printing of deprecated string exceptions with a
69 value in the traceback module.
70
Greg Ward48fae7a2006-07-23 16:05:51 +000071- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
72
Martin v. Löwis426f4a12006-07-18 17:46:31 +000073- Patch #1524429: Use repr() instead of backticks in Tkinter again.
74
Brett Cannoncaebe222006-07-18 04:41:36 +000075- Bug #1520914: Change time.strftime() to accept a zero for any position in its
76 argument tuple. For arguments where zero is illegal, the value is forced to
77 the minimum value that is correct. This is to support an undocumented but
78 common way people used to fill in inconsequential information in the time
79 tuple pre-2.4.
80
Bob Ippolito5ea4bf12006-07-15 16:53:15 +000081- Patch #1220874: Update the binhex module for Mach-O.
82
Barry Warsawb110bad2006-07-21 14:51:07 +000083- The email package has improved RFC 2231 support, specifically for
84 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
85 (name*0=<blah>) parameter continuations. This may change the types of
86 values returned from email.message.Message.get_param() and friends.
87 Specifically in some cases where non-encoded continuations were used,
88 get_param() used to return a 3-tuple of (None, None, string) whereas now it
89 will just return the string (since non-encoded continuations don't have
90 charset and language parts).
91
92 Also, whereas % values were decoded in all parameter continuations, they are
93 now only decoded in encoded parameter parts.
94
Ronald Oussoren3075e162006-07-25 20:28:55 +000095- Bug #1517990: IDLE keybindings on MacOS X now work correctly
96
97- Bug #1517996: IDLE now longer shows the default Tk menu when a
98 path browser, class browser or debugger is the frontmost window on MacOS X
99
Barry Warsaw00decd72006-07-27 23:43:15 +0000100- Patch #1520294: Support for getset and member descriptors in types.py,
101 inspect.py, and pydoc.py. Specifically, this allows for querying the type
102 of an object against these built-in types and more importantly, for getting
103 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +0000106Extension Modules
107-----------------
108
Tim Petersbc24eee2006-07-27 01:14:53 +0000109- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000110 Paul Eggert.
111
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000112- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
113
Thomas Hellerce049a02006-07-14 17:51:14 +0000114- Patch #1521817: Index range checking on ctypes arrays containing
115 exactly one element enabled again. This allows iterating over these
116 arrays, without the need to check the array size before.
117
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000118- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000119 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000120 /dev/null in certain cases; this is now fixed.
121
Thomas Heller47d7a062006-07-12 08:43:47 +0000122- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
123 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000124
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000125- Because of a misspelled preprocessor symbol, ctypes was always
126 compiled without thread support; this is now fixed.
127
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000128Tests
129-----
130
131- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
132 how long the test file should take to play. Now accepts taking 2.93 secs
133 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
134
Georg Brandl6cea7d72006-07-27 15:38:33 +0000135- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``
136 and ``test_uuid`` didn't actually run any tests when run via ``regrtest.py``.
137 Now they do.

145Core and builtins
146-----------------
147
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000148- Bug #1441486: The literal representation of -(sys.maxint - 1)
149 again evaluates to a int object, not a long.
150
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000151- Bug #1501934: The scope of global variables that are locally assigned
152 using augmented assignment is now correctly determined.
153
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000154- Bug #927248: Recursive method-wrapper objects can now safely
155 be released.
156
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000157- Bug #1417699: Reject locale-specific decimal point in float()
158 and atof().
159
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000160- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
161 omit a default "error" argument for NULL pointer. This allows
162 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000163
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000164- Bug #1519018: 'as' is now validated properly in import statements.
165
Neal Norwitz28746ab2006-07-09 22:14:42 +0000166- On 64 bit systems, int literals that use less than 64 bits are
167 now ints rather than longs.
168
Neal Norwitzed657552006-07-10 00:04:44 +0000169- Bug #1512814, Fix incorrect lineno's when code at module scope
170 started after line 256.
171
Tim Peters32a83612006-07-10 21:08:24 +0000172- New function ``sys._current_frames()`` returns a dict mapping thread
173 id to topmost thread stack frame. This is for expert use, and is
174 especially useful for debugging application deadlocks. The functionality
175 was previously available in Fazal Majid's ``threadframe`` extension
176 module, but it wasn't possible to do this in a wholly threadsafe way from
177 an extension.

191
Thomas Woutersadd19112006-07-05 11:03:49 +0000192- string.Template() now correctly handles tuple-values. Previously,
193 multi-value tuples would raise an exception and single-value tuples would
194 be treated as the value they contain, instead.
195
Martin v. Löwisede77f52006-07-03 13:01:35 +0000196- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
197 even if some data are received.
198
Martin v. Löwis45482392006-07-03 12:28:58 +0000199- Bug #1267547: Put proper recursive setup.py call into the

Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000207
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000208- Bug #1514703: Only setup canvas window in turtle when the canvas

221
Brett Cannon53ab5b72006-06-22 16:49:14 +0000222- Bug #1510580: The 'warnings' module improperly required that a Warning
223 category be either a types.ClassType and a subclass of Warning. The proper
224 check is just that it is a subclass with Warning as the documentation states.
225
Georg Brandlad29e632006-06-21 17:45:17 +0000226- The compiler module now correctly compiles the new try-except-finally
227 statement (bug #1509132).
228
Neal Norwitz60373cd2006-06-22 06:30:50 +0000229- The wsgiref package is now installed properly on Unix.

235 null character before sending it to a custom converter. This has been fixed
236 now.
237
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000238Extension Modules
239-----------------
240
Tim Peters112aad32006-07-19 00:03:19 +0000241- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
242 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
243 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000244
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000245- Assigning None to pointer type fields in ctypes structures possible
246 overwrote the wrong fields, this is fixed now.
247
248- Fixed a segfault in _ctypes when ctypes.wintypes were imported
249 on non-Windows platforms.
250
251- Bug #1518190: The ctypes.c_void_p constructor now accepts any
252 integer or long, without range checking.
253
254- Patch #1517790: It is now possible to use custom objects in the ctypes
255 foreign function argtypes sequence as long as they provide a from_param
256 method, no longer is it required that the object is a ctypes type.
257
258- The '_ctypes' extension module now works when Python is configured
259 with the --without-threads option.
260
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000261- Bug #1513646: os.access on Windows now correctly determines write
262 access, again.

276
Tim Peters32a83612006-07-10 21:08:24 +0000277- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000278 Previously, the slight difference could cause compilation errors of the
279 'zlib' module on systems with more than one version of zlib.
280
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000281- The MSI compileall step was fixed to also support a TARGETDIR

312-----------------
313
Georg Brandla56b9152006-06-19 06:35:54 +0000314- Patch #1507676: Error messages returned by invalid abstract object operations
315 (such as iterating over an integer) have been improved and now include the
316 type of the offending object to help with debugging.
317
Brett Cannonea3912b2006-06-13 21:46:41 +0000318- Bug #992017: A classic class that defined a __coerce__() method that returned
319 its arguments swapped would infinitely recurse and segfault the interpreter.
320
Neal Norwitz909eb122006-06-12 02:13:21 +0000321- Fix the socket tests so they can be run concurrently.
322
Neal Norwitzb9845e72006-06-12 02:11:18 +0000323- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000324 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000325
Brett Cannon22565aa2006-06-09 22:31:23 +0000326- Bug #532646: object.__call__() will continue looking for the __call__
327 attribute on objects until one without one is found. This leads to recursion
328 when you take a class and set its __call__ attribute to an instance of the
329 class. Originally fixed for classic classes, but this fix is for new-style.
330 Removes the infinite_rec_3 crasher.
331
Georg Brandl24250812006-06-09 18:45:48 +0000332- The string and unicode methods startswith() and endswith() now accept
333 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
334
Brett Cannonde3b0522006-06-08 17:00:45 +0000335- Buffer objects, at the C level, never used the char buffer
336 implementation even when the char buffer for the wrapped object was
337 explicitly requested (originally returned the read or write buffer).
338 Now a TypeError is raised if the char buffer is not present but is
339 requested.
340
Georg Brandlddbaa662006-06-04 21:56:52 +0000341- Patch #1346214: Statements like "if 0: suite" are now again optimized
342 away like they were in Python 2.4.
343
Georg Brandlb7c8f542006-05-27 12:30:25 +0000344- Builtin exceptions are now full-blown new-style classes instead of
345 instances pretending to be classes, which speeds up exception handling
346 by about 80% in comparison to 2.5a2.
347
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000348- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
349 Unicode 4.1.
350
Georg Brandlf4ef1162006-05-26 18:03:31 +0000351- Patch #921466: sys.path_importer_cache is now used to cache valid and
352 invalid file paths for the built-in import machinery which leads to
353 fewer open calls on startup.
354
Tim Peters696cf432006-05-24 21:10:40 +0000355- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
356 of-2 bases. The largest speedup is for inputs with about 1000 decimal
357 digits. Conversion from non-power-of-2 bases remains quadratic-time in
358 the number of input digits (it was and remains linear-time for bases
359 2, 4, 8, 16 and 32).
360
Tim Petersb713ec22006-05-23 18:45:30 +0000361- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
362 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
363 an integer close to ``sys.maxint``. This was repaired by patch
364 #1335972, which also gives a nice speedup.
365
Richard Jonescebbefc2006-05-23 18:28:17 +0000366- Patch #1337051: reduced size of frame objects.
367
368- PyErr_NewException now accepts a tuple of base classes as its
369 "base" parameter.
370
Richard Jones7c88dcc2006-05-23 10:37:38 +0000371- Patch #876206: function call speedup by retaining allocated frame
372 objects.
373
Georg Brandl7b90e162006-05-18 07:01:27 +0000374- Bug #1462152: file() now checks more thoroughly for invalid mode
375 strings and removes a possible "U" before passing the mode to the
376 C library function.
377
Neal Norwitz1004a532006-05-15 07:17:23 +0000378- Patch #1488312, Fix memory alignment problem on SPARC in unicode
379
Neal Norwitz373f0a72006-05-15 07:04:36 +0000380- Bug #1487966: Fix SystemError with conditional expression in assignment
381
Martin v. Löwis879768d2006-05-11 13:28:43 +0000382- WindowsError now has two error code attributes: errno, which carries
383 the error values from errno.h, and winerror, which carries the error
384 values from winerror.h. Previous versions put the winerror.h values
385 (from GetLastError()) into the errno attribute.
386
Martin v. Löwis77736712006-05-04 05:51:03 +0000387- Patch #1475845: Raise IndentationError for unexpected indent.
388
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000389- Patch #1479181: split open() and file() from being aliases for each other.
390
Tim Peters44bd9862006-06-01 13:49:23 +0000391- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
392 methods were always silently ignored by dictionaries when comparing keys.
393 They are now passed through (except when using the C API function
394 ``PyDict_GetItem()``, whose semantics did not change).
395
396- Bug #1456209: In some obscure cases it was possible for a class with a
397 custom ``__eq__()`` method to confuse dict internals when class instances
398 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
399 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000401Extension Modules
402-----------------
403
Trent Mick960a3f82006-06-28 20:30:41 +0000404- Bug #1295808: expat symbols should be namespaced in pyexpat
405
406- Patch #1462338: Upgrade pyexpat to expat 2.0.0
407
Brett Cannon6ee7d012006-06-08 16:23:04 +0000408- Change binascii.hexlify to accept a read-only buffer instead of only a char
409 buffer and actually follow its documentation.
410
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000411- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
412
Nick Coghlanc649ec52006-05-29 12:43:05 +0000413- Patch #1478788 (modified version): The functional extension module has
414 been renamed to _functools and a functools Python wrapper module added.
415 This provides a home for additional function related utilities that are
416 not specifically about functional programming. See PEP 309.
417
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000418- Patch #1493701: performance enhancements for struct module.
419
Georg Brandl378d5922006-05-17 14:26:50 +0000420- Patch #1490224: time.altzone is now set correctly on Cygwin.
421
Georg Brandl8d3342b2006-05-16 07:38:27 +0000422- Patch #1435422: zlib's compress and decompress objects now have a
423 copy() method.
424
Andrew MacIntyre92913322006-06-13 15:04:24 +0000425- Patch #1454481: thread stack size is now tunable at runtime for thread
426 enabled builds on Windows and systems with Posix threads support.
427
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000428- On Win32, os.listdir now supports arbitrarily-long Unicode path names
429 (up to the system limit of 32K characters).
430
431- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
432 As a result, these functions now raise WindowsError instead of OSError.
433
Tim Peters7a822da2006-05-25 21:50:17 +0000434- ``time.clock()`` on Win64 should use the high-performance Windows
435 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
436 Windows platforms).
437
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000438- Calling Tk_Init twice is refused if the first call failed as that
439 may deadlock.
440
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000441- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
442 accept it without potentially using an uninitialized pointer.
443
444- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
445 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
446 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000447
Gregory P. Smith372b5832006-06-05 18:48:21 +0000448- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000449 [pybsddb project SF patch number 1466734]
450
Gregory P. Smith372b5832006-06-05 18:48:21 +0000451- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
452 parameter is supplied. [SF pybsddb bug #1477863]
453
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000454- bsddb: the __len__ method of a DB object has been fixed to return correct
455 results. It could previously incorrectly return 0 in some cases.
456 Fixes SF bug 1493322 (pybsddb bug 1184012).
457
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000458- bsddb: the bsddb.dbtables Modify method now raises the proper error and
459 aborts the db transaction safely when a modifier callback fails.
460 Fixes SF python patch/bug #1408584.
461
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000462- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000463 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000464 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
465 database calls that would previously deadlock. [SF python bug #775414]
466
Vinay Sajip28e57612006-07-01 10:45:20 +0000467- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000468
Walter Dörwald4994d952006-06-19 08:07:50 +0000469- Patch #1506645: add Python wrappers for the curses functions
470 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000471

473-------
474
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000475- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
476 functions.
477
Martin v. Löwis3798da02006-06-17 18:44:27 +0000478- Patch #812986: Update turtle output even if not tracing.
479
Vinay Sajip28e57612006-07-01 10:45:20 +0000480- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000481 Tkinter.BaseWidget.
482
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000483- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
484
Martin v. Löwis337487e2006-06-17 09:15:14 +0000485- Patch #763580: Add name and value arguments to Tkinter variable
486 classes.
487
Georg Brandl83cc0d02006-06-14 08:50:03 +0000488- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
489 mime.types file for determining MIME types.
490
Georg Brandl2605ca82006-06-14 06:08:31 +0000491- Bug #1339007: Shelf objects now don't raise an exception in their
492 __del__ method when initialization failed.
493
Martin v. Löwisd8251432006-06-14 05:21:04 +0000494- Patch #1455898: The MBCS codec now supports the incremental mode for
495 double-byte encodings.
496
Tim Peters43898b42006-06-14 04:09:25 +0000497- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
498 guarantee that adjacent triples in the return list always describe
499 non-adjacent blocks. Previously, a pair of matching blocks could end
500 up being described by multiple adjacent triples that formed a partition
501 of the matching pair.
502
Greg Ward0e0c9f42006-06-11 16:24:11 +0000503- Bug #1498146: fix optparse to handle Unicode strings in option help,
504 description, and epilog.
505
Greg Wardd1c797e2006-06-11 14:42:41 +0000506- Bug #1366250: minor optparse documentation error.
507
Greg Ward7f547402006-06-11 00:40:49 +0000508- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
509 clarify docs.
510
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000511- The wsgiref package has been added to the standard library.
512
Nick Coghlan676725d2006-06-08 13:54:49 +0000513- The functions update_wrapper() and wraps() have been added to the functools
514 module. These make it easier to copy relevant metadata from the original
515 function when writing wrapper functions.
516
Tim Petersd6a9eef2006-06-05 01:48:21 +0000517- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
518 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000519
Martin v. Löwis3f767792006-06-04 19:36:28 +0000520- Patch #1359618: Speed up charmap encoder by using a trie structure
521 for lookup.
522
Tim Petersd609b1a2006-06-02 23:22:51 +0000523- The functions in the ``pprint`` module now sort dictionaries by key
524 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
525 if and only if its display required more than one line, although that
526 wasn't documented. The new behavior increases predictability; e.g.,
527 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
528
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000529- Patch #1497027: try HTTP digest auth before basic auth in urllib2
530 (thanks for J. J. Lee).
531
Georg Brandl2b330372006-05-28 20:23:12 +0000532- Patch #1496206: improve urllib2 handling of passwords with respect to
533 default HTTP and HTTPS ports.
534
George Yoshidaf3c65de2006-05-28 16:39:09 +0000535- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
536
Bob Ippolito7298f272006-05-23 18:43:47 +0000537- Patch #1281707: speed up gzip.readline.
538
Georg Brandlb89316f2006-05-17 15:51:16 +0000539- Patch #1180296: Two new functions were added to the locale module:
540 format_string() to get the effect of "format % items" but locale-aware,
541 and currency() to format a monetary number with currency sign.
542
Georg Brandle3a25832006-05-17 14:56:04 +0000543- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
544 and several features added, such as speed and geometry control.
545
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000546- Patch #1488881: add support for external file objects in bz2 compressed
547 tarfiles.
548
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000549- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
550 stdout arguments, making it possible to redirect input and output
551 for remote debugging.
552
553- Patch #1484695: Update the tarfile module to version 0.8. This fixes
554 a couple of issues, notably handling of long file names using the
555 GNU LONGNAME extension.
556
557- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
558 new flag when ``name`` is already the name of an option flag.
559
560- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
561 package.
562
563- Patch #1472854: make the rlcompleter.Completer class usable on non-
564 UNIX platforms.
565
566- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
567
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000568- Bug #1472827: correctly escape newlines and tabs in attribute values in
569 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000599What's New in Python 2.5 alpha 2?
600=================================
601
602*Release date: 27-APR-2006*
603
604Core and builtins
605-----------------
606
Thomas Heller1b046642006-04-18 18:51:06 +0000607- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
608 by converting these apis from macros into exported functions again:
609
610 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
611 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
612 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
613 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
614 PyRun_String Py_CompileString
615
Martin v. Löwis45294a92006-04-18 06:24:08 +0000616- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
617
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000618- All uses of PyStructSequence_InitType have been changed to initialize
619 the type objects only once, even if the interpreter is initialized
620 multiple times.
621
Neal Norwitz61546162006-04-14 05:20:28 +0000622- Bug #1454485, array.array('u') could crash the interpreter. This was
623 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
624 to unicode when it didn't make sense. 'u#' now requires a unicode string.
625
626- Py_UNICODE is unsigned. It was always documented as unsigned, but
627 due to a bug had a signed value in previous versions.

Tim Peters3a5e8b12006-04-11 01:44:07 +0000629- Patch #837242: ``id()`` of any Python object always gives a positive
630 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
631 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000632 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000633 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000634
Tim Peters3a5e8b12006-04-11 01:44:07 +0000635 def __hash__(self):
636 return id(self) # WRONG
637
638 because a hash result must be a (short) Python int but it was always
639 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000640 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000641 was always usable as a hash value before this patch. That's no longer
642 necessarily so.
643
644- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000645 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000646 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000647 #1454844)
648
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000649- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
650 involving generators that have paused outside of any ``try`` or ``with``
651 blocks. (In 2.5a1, a paused generator that was part of a reference
652 cycle could not be garbage collected, regardless of whether it was
653 paused in a ``try`` or ``with`` block.)

659 is a macro.
660
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000661- Bug #1467952: os.listdir() now correctly raises an error if readdir()
662 fails with an error condition.
663
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000664- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
665
666- Bug #1117761: bsddb.*open() no longer raises an exception when using
667 the cachesize parameter.
668
669- Bug #1149413: bsddb.*open() no longer raises an exception when using
670 a temporary db (file=None) with the 'n' flag to truncate on open.
671
672- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
673 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000674
Armin Rigoa9017c32006-04-19 11:50:27 +0000675- Patch #1062014: AF_UNIX sockets under Linux have a special
676 abstract namespace that is now fully supported.
677
Anthony Baxter51bcb682006-04-05 14:51:42 +0000678Library
679-------
680
Peter Astrand7d1d4362006-07-14 14:04:45 +0000681- Bug #1223937: subprocess.CalledProcessError reports the exit status
682 of the process using the returncode attribute, instead of
683 abusing errno.
684
Tim Peters711bf302006-04-25 03:31:36 +0000685- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
686 a doctest to be skipped (the code is not run, and the expected output
687 or exception is ignored).
688
Nick Coghlanda2268f2006-04-24 04:37:15 +0000689- Fixed contextlib.nested to cope with exceptions being raised and
690 caught inside exit handlers.
691
Greg Wardab05edc2006-04-23 03:47:58 +0000692- Updated optparse module to Optik 1.5.1 (allow numeric constants in
693 hex, octal, or binary; add ``append_const`` action; keep going if
694 gettext cannot be imported; added ``OptionParser.destroy()`` method;
695 added ``epilog`` for better help generation).
696
Tim Peters21fbd572006-04-21 21:18:10 +0000697- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
698 called from a thread spawned as a side effect of importing a module.
699
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000700- The pydoc module now supports documenting packages contained in
701 .zip or .egg files.
702
703- The pkgutil module now has several new utility functions, such
704 as ``walk_packages()`` to support working with packages that are either
705 in the filesystem or zip files.
706
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000707- The mailbox module can now modify and delete messages from
708 mailboxes, in addition to simply reading them. Thanks to Gregory
709 K. Johnson for writing the code, and to the 2005 Google Summer of
710 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000711
Tim Petersc7605f22006-04-17 21:12:33 +0000712- The ``__del__`` method of class ``local`` in module ``_threading_local``
713 returned before accomplishing any of its intended cleanup.

Anthony Baxtere29002c2006-04-12 12:07:31 +0000721- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
722 Windows. Bug #1469163.
723
Phillip J. Eby47032112006-04-11 01:07:43 +0000724- The warnings, linecache, inspect, traceback, site, and doctest modules
725 were updated to work correctly with modules imported from zipfiles or
726 via other PEP 302 __loader__ objects.

734
Skip Montanaro262fb922006-04-21 02:31:07 +0000735- The pstats.Stats class accepts an optional stream keyword argument to
736 direct output to an alternate file-like object.
737
Anthony Baxter51bcb682006-04-05 14:51:42 +0000738Build
739-----
740
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000741- The Makefile now has a reindent target, which runs reindent.py on
742 the library.
743
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000744- Patch #1470875: Building Python with MS Free Compiler
745
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000746- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000747
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000748- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
749 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000750 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000751 CXX from --with-cxx-main, see description in README.
752
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000753- Patch #1429775: Link extension modules with the shared libpython.
754
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000755- Fixed a libffi build problem on MIPS systems.
756
Tim Peters8931ff12006-05-13 23:28:20 +0000757- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
758 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
759 and "%zu" for unsigned integers of type ``size_t``.
760
Anthony Baxter51bcb682006-04-05 14:51:42 +0000761Tests
762-----
763
Nick Coghlanda2268f2006-04-24 04:37:15 +0000764- test_contextlib now checks contextlib.nested can cope with exceptions
765 being raised and caught inside exit handlers.
766
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000767- test_cmd_line now checks operation of the -m and -c command switches
768
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000769- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
770 it separately and by hand. It also wasn't cleaning up its changes to
771 the current Decimal context.
772
Thomas Woutersabd08882006-04-26 15:53:30 +0000773- regrtest.py now has a -M option to run tests that test the new limits of
774 containers, on 64-bit architectures. Running these tests is only sensible
775 on 64-bit machines with more than two gigabytes of memory. The argument
776 passed is the maximum amount of memory for the tests to use.

785-------------
786
Tim Petersb06d28c2006-05-12 01:57:59 +0000787- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
788
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000789- PEP 343: Added Context Types section to the library reference
790 and attempted to bring other PEP 343 related documentation into
791 line with the implementation and/or python-dev discussions.
792
Tim Peters8dc73d22006-04-24 02:03:16 +0000793- Bug #1337990: clarified that ``doctest`` does not support examples
794 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000797What's New in Python 2.5 alpha 1?
798=================================
799
Anthony Baxterebed3f62006-04-03 15:03:44 +0000800*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000801
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000802Core and builtins
803-----------------
804
Nick Coghlan43832302006-04-23 17:04:07 +0000805- PEP 338: -m command line switch now delegates to runpy.run_module
806 allowing it to support modules in packages and zipfiles
807
Martin v. Löwisc661b882006-04-20 04:54:23 +0000808- On Windows, .DLL is not an accepted file name extension for
809 extension modules anymore; extensions are only found if they
810 end in .PYD.
811
Martin v. Löwisea62d252006-04-03 10:56:49 +0000812- Bug #1421664: sys.stderr.encoding is now set to the same value as
813 sys.stdout.encoding.
814
Neal Norwitz92e212f2006-04-03 04:48:37 +0000815- __import__ accepts keyword arguments.
816
Georg Brandlccadf842006-03-31 18:54:53 +0000817- Patch #1460496: round() now accepts keyword arguments.
818
Anthony Baxter262c00a2006-03-30 10:53:17 +0000819- Fixed bug #1459029 - unicode reprs were double-escaped.
820
Hye-Shik Changd478f342006-03-23 12:32:36 +0000821- Patch #1396919: The system scope threads are reenabled on FreeBSD
822 5.4 and later versions.
823
Neal Norwitze98ccf62006-03-23 05:39:47 +0000824- Bug #1115379: Compiling a Unicode string with an encoding declaration
825 now gives a SyntaxError.
826
Georg Brandlabd1ff82006-03-18 07:59:59 +0000827- Previously, Python code had no easy way to access the contents of a
828 cell object. Now, a ``cell_contents`` attribute has been added
829 (closes patch #1170323).
830
Tim Peterscf79aac2006-03-16 01:14:46 +0000831- Patch #1123430: Python's small-object allocator now returns an arena to
832 the system ``free()`` when all memory within an arena becomes unused
833 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
834 freed. Some applications will see a drop in virtual memory size now,
835 especially long-running applications that, from time to time, temporarily
836 use a large number of small objects. Note that when Python returns an
837 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000838 platform C library will in turn return that memory to the operating system.
839 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000840 appears to be effective at least on Microsoft C and gcc-based systems.
841 Thanks to Evan Jones for hard work and patience.
842
Georg Brandl533ff6f2006-03-08 18:09:27 +0000843- Patch #1434038: property() now uses the getter's docstring if there is
844 no "doc" argument given. This makes it possible to legitimately use
845 property() as a decorator to produce a read-only property.
846
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000847- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
848 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
849 of requiring an int or long in slicing and a few other contexts, enabling
850 other objects (e.g. Numeric Python's integers) to be used as slice indices.
851
Neal Norwitz995acdf2006-03-07 05:01:00 +0000852- Fixed various bugs reported by Coverity's Prevent tool.
853
Brett Cannonbf364092006-03-01 04:25:17 +0000854- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
855 new exception base class, BaseException, which has a new message attribute.
856 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
857 Raising a string exception now raises a DeprecationWarning.
858
Thomas Woutersfb609f42006-02-28 16:37:25 +0000859- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
860 explicitly relative, using 'from .module import name' to mean 'from the same
861 package as this module is in. Imports without dots still default to the
862 old relative-then-absolute, unless 'from __future__ import
863 absolute_import' is used.
864
Brett Cannona7446e32006-02-27 23:39:10 +0000865- Properly check if 'warnings' raises an exception (usually when a filter set
866 to "error" is triggered) when raising a warning for raising string
867 exceptions.
868
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000869- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000870 The name was removed from Include/code.h.
871
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000872- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000873
Guido van Rossum1968ad32006-02-25 22:38:04 +0000874- Patch 1433928:
875 - The copy module now "copies" function objects (as atomic objects).
876 - dict.__getitem__ now looks for a __missing__ hook before raising
877 KeyError.
878
Tim Peters84ef21c2006-02-28 20:39:06 +0000879- PEP 343: with statement implemented. Needs ``from __future__ import
880 with_statement``. Use of 'with' as a variable will generate a warning.
881 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000882 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000883 The following objects have __context__ methods:
884 - The built-in file type.
885 - The thread.LockType type.
886 - The following types defined by the threading module:
887 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
888 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000889
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000890- Fix the encodings package codec search function to only search
891 inside its own package. Fixes problem reported in patch #1433198.
892
893 Note: Codec packages should implement and register their own
894 codec search function. PEP 100 has the details.
895
Tim Peters9ea89d22006-06-04 03:26:02 +0000896- PEP 353: Using ``Py_ssize_t`` as the index type.
897
898- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
899 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
900 now allow Python to make use of memory blocks exceeding 2**32 bytes for
901 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
902 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000903
Neal Norwitzfc76d632006-01-10 06:03:13 +0000904- Patch #1400181, fix unicode string formatting to not use the locale.
905 This is how string objects work. u'%f' could use , instead of .
906 for the decimal point. Now both strings and unicode always use periods.
907
Neal Norwitz671b9e32006-01-09 07:07:12 +0000908- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
909 configure would break checking curses.h.
910
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000911- Bug #959576: The pwd module is now builtin. This allows Python to be
912 built on UNIX platforms without $HOME set.
913
Neal Norwitzc10978f2005-12-19 06:07:16 +0000914- Bug #1072182, fix some potential problems if characters are signed.
915
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000916- Bug #889500, fix line number on SyntaxWarning for global declarations.
917
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000918- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
919
Neal Norwitze7214a12005-12-18 05:03:17 +0000920- Support for converting hex strings to floats no longer works.
921 This was not portable. float('0x3') now raises a ValueError.
922
Barry Warsaw2a38a862005-12-18 01:27:35 +0000923- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000924 function Py_GetBuildNumber(). New attribute sys.subversion. Build number

926
Georg Brandlfa166682005-12-17 21:45:17 +0000927- Implementation of PEP 341 - Unification of try/except and try/finally.
928 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000929 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000930
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000931- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
932 now encodes backslash correctly.
933
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000934- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
935
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000936- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000937 and long longs.
938
Neal Norwitz67715f02005-11-09 06:59:35 +0000939- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000940 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000941 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000942
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000943- Replaced most Unicode charmap codecs with new ones using the
944 new Unicode translate string feature in the builtin charmap
945 codec; the codecs were created from the mapping tables available
946 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
947 encodings now include a mapping for the Apple logo)
948
Tim Peterse3547fd2005-12-16 23:13:57 +0000949- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000950
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000951- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000952
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000953- A new AST parser implementation was completed. The abstract
954 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000955 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000956
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000957- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000958 The following code now raises a SyntaxError: foo(a = i for i in range(10))
959
Neal Norwitz708e51a2005-10-03 04:48:15 +0000960- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
961
Neal Norwitz11bd1192005-10-03 00:54:56 +0000962- SF Bug #887946: fix segfault when redirecting stdin from a directory.
963 Provide a warning when a directory is passed on the command line.
964
Neal Norwitz40d37812005-10-02 01:48:49 +0000965- Fix segfault with invalid coding.
966
967- SF bug #772896: unknown encoding results in MemoryError.
968
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000969- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000970 supported a __len__() method which evaluated to False when the iterator
971 was empty.
972
Guido van Rossum630db602005-09-20 18:49:54 +0000973- On 64-bit platforms, when __len__() returns a value that cannot be
974 represented as a C int, raise OverflowError.
975
Skip Montanarof8948ca2005-09-19 03:54:46 +0000976- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000977 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000978
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000979- SF bug #893549: parsing keyword arguments was broken with a few format
980 codes.
981
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000982- Changes donated by Elemental Security to make it work on AIX 5.3
983 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
984 bug #105470: test_pwd fails on 64bit system (Opteron).
985
Guido van Rossum539c6622005-09-14 17:49:54 +0000986- Changes donated by Elemental Security to make it work on HP-UX 11 on
987 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
988
Georg Brandl4550b8d2005-08-26 06:43:52 +0000989- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000990 (fixes bug #1119418).
991
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000992- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
993
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000994- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
995 exceptions that cause a function to exit.
996
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000997- The implementation of set() and frozenset() was revised to use its
998 own internal data structure. Memory consumption is reduced by 1/3
999 and there are modest speed-ups as well. The API is unchanged.
1000
Tim Petersde7990b2005-07-17 23:45:23 +00001001- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1002
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001003- SF bug #1229429: PyObject_CallMethod failed to decrement some
1004 reference counts in some error exit cases.
1005
Tim Petersecc6e6a2005-07-10 22:30:55 +00001006- SF bug #1185883: Python's small-object memory allocator took over
1007 a block managed by the platform C library whenever a realloc specified
1008 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001009 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001010 portable way to copy data from the C-managed block into Python's
1011 small-object space without risking a memory fault. Python's small-object
1012 realloc now leaves such blocks under the control of the platform C
1013 realloc.
1014
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001015- SF bug #1232517: An overflow error was not detected properly when
1016 attempting to convert a large float to an int in os.utime().
1017
Raymond Hettinger3296e692005-06-29 23:29:56 +00001018- SF bug #1224347: hex longs now print with lowercase letters just
1019 like their int counterparts.
1020
Michael W. Hudson188d4362005-06-20 16:52:57 +00001021- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1022 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1023 interpreter states; back out that fix and do a better job (see
1024 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1025 for a longer write-up of the problem).
1026
Michael W. Hudsondf888462005-06-03 14:41:55 +00001027- SF patch #1180995: marshal now uses a binary format by default when
1028 serializing floats.
1029
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001030- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1031 the routines that promise to produce IEEE 754 binary representations
1032 of floats now simply copy bytes around.
1033
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001034- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1035 278.
1036
Brett Cannonc3647ac2005-04-26 03:45:26 +00001037- patch #1109424: int, long, float, complex, and unicode now check for the
1038 proper magic slot for type conversions when subclassed. Previously the
1039 magic slot was ignored during conversion. Semantics now match the way
1040 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001041 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001042 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001043 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001044
Barry Warsawc8d907c2005-04-19 23:43:40 +00001045- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1046 NULL, now raise an AttributeError when attempting to set or delete the
1047 attribute. Previously a TypeError was raised, but this was inconsistent
1048 with the equivalent pure-Python implementation.
1049
Michael W. Hudson774479c2005-04-18 08:46:17 +00001050- It is now safe to call PyGILState_Release() before
1051 PyEval_InitThreads() (note that if there is reason to believe there
1052 are multiple threads around you still must call PyEval_InitThreads()
1053 before using the Python API; this fix is for extension modules that
1054 have no way of knowing if Python is multi-threaded yet).
1055
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001056- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1057 disabled caused a crash.
1058
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001059- Bug #1165306: instancemethod_new allowed the creation of a method
1060 with im_class == im_self == NULL, which caused a crash when called.
1061
Tim Petersecc6e6a2005-07-10 22:30:55 +00001062- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001063 fixes the crash seen in bug #1165761
1064
Raymond Hettinger96229b12005-03-11 06:49:40 +00001065- Added two new builtins, any() and all().
1066
Brett Cannon409d8f22005-03-05 06:47:57 +00001067- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001068 (e.g., ``class C(): pass`` is no longer a syntax error).
1069 Patch #1176012 added support to the 'parser' module and 'compiler' package
1070 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001071
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001072- Patch #1115086: Support PY_LONGLONG in structmember.
1073
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001074- Bug #1155938: new style classes did not check that __init__() was
1075 returning None.
1076
Tim Petersecc6e6a2005-07-10 22:30:55 +00001077- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001078 ('\') with a specific error message.
1079
Martin v. Löwisff232d72005-03-03 09:24:38 +00001080- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1081
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001082- Bug #1124295: the __name__ attribute of file objects was
1083 inadvertently made inaccessible in restricted mode.
1084
Tim Petersecc6e6a2005-07-10 22:30:55 +00001085- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001086 an ferror() call.
1087
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001088- min() and max() now support key= arguments with the same meaning as in
1089 list.sort().
1090
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001091- The peephole optimizer now performs simple constant folding in expressions:
1092 (2+3) --> (5).
1093
Raymond Hettingera422c342005-01-11 03:03:27 +00001094- set and frozenset objects can now be marshalled. SF #1098985.
1095
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001096- Bug #1077106: Poor argument checking could cause memory corruption
1097 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001098
Jeremy Hyltonab630502005-02-04 18:44:06 +00001099- The parser did not complain about future statements in illegal
1100 positions. It once again reports a syntax error if a future
1101 statement occurs after anything other than a doc string.
1102
Neil Schemenauercf52c072005-08-12 17:34:58 +00001103- Change the %s format specifier for str objects so that it returns a
1104 unicode instance if the argument is not an instance of basestring and
1105 calling __str__ on the argument returns a unicode instance.
1106
Tim Petersf4e69282006-02-27 17:15:31 +00001107- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1108 current thread state when the auto-GIL-state machinery knows about
1109 it (since the thread state is being deleted, continuing to remember it
1110 can't help, but can hurt if another thread happens to get created with
1111 the same thread id).
1112
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001113Extension Modules
1114-----------------
1115
Georg Brandl43f08a82006-03-31 18:01:16 +00001116- Patch #1380952: fix SSL objects timing out on consecutive read()s

1119
Anthony Baxterfa869072006-03-20 05:21:58 +00001120- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1121 In addition, the existing ulaw code was updated.
1122
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001123- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001124 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001125
Neal Norwitz10be10c2006-03-16 06:50:13 +00001126- Everything under lib-old was removed. This includes the following modules:
1127 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001128 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001129 util, whatsound, whrandom, zmod
1130
1131- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1132
1133- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001134 is deprecated. The undocumented re.engine variable no longer exists.
1135
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001136- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1137 SS2 (single-shift 2) escape sequences correctly.
1138
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001139- The unicodedata module was updated to the 4.1 version of the Unicode
1140 database. The 3.2 version is still available as unicodedata.db_3_2_0
1141 for applications that require this specific version (such as IDNA).
1142
Neal Norwitzb62c4332006-03-04 18:35:47 +00001143- The timing module is no longer built by default. It was deprecated
1144 in PEP 4 in Python 2.0 or earlier.
1145
Guido van Rossum1968ad32006-02-25 22:38:04 +00001146- Patch 1433928: Added a new type, defaultdict, to the collections module.
1147 This uses the new __missing__ hook behavior added to dict (see above).
1148
Georg Brandldbd83392006-02-20 09:42:33 +00001149- Bug #854823: socketmodule now builds on Sun platforms even when
1150 INET_ADDRSTRLEN is not defined.
1151
Georg Brandlf4f44152006-02-18 22:29:33 +00001152- Patch #1393157: os.startfile() now has an optional argument to specify
1153 a "command verb" to invoke on the file.
1154
Neal Norwitz082b2df2006-02-07 07:04:46 +00001155- Bug #876637, prevent stack corruption when socket descriptor
1156 is larger than FD_SETSIZE.
1157
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001158- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1159 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1160 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1161
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001162- Patch #1422385: The nis module now supports access to domains other
1163 than the system default domain.
1164
Martin v. Löwis14694662006-02-03 12:54:16 +00001165- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1166 are reported, the limit on path name lengths is removed, and stat reports
1167 WindowsError now (instead of OSError).
1168
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001169- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
1170
Neal Norwitz62a21122006-01-25 05:21:55 +00001171- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
1172 before the env.
1173

1179 Also fix ungetmouse() which did not accept arguments properly.
1180 The code now conforms to the documented signature.
1181
Neal Norwitz5e3d8622006-01-09 06:24:35 +00001182- Bug #1400115, Fix segfault when calling curses.panel.userptr()
1183 without prior setting of the userptr.
1184
Neal Norwitz40c6b472006-01-05 05:43:35 +00001185- Fix 64-bit problems in bsddb.
1186

1244 the request code argument, which results in more C-like behaviour
1245 for large or negative values.
1246

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001303- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1304 been renamed to have only a single underscore prefix. This was done to
1305 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001306
Nick Coghlan43832302006-04-23 17:04:07 +00001307- PEP 338: new module runpy defines a run_module function to support
1308 executing modules which provide access to source code or a code object
1309 via the PEP 302 import mechanisms.
1310
Anthony Baxter93f5b932006-04-03 08:05:07 +00001311- The email module's parsedate_tz function now sets the daylight savings
1312 flag to -1 (unknown) since it can't tell from the date whether it should

1319 in attribute values.
1320
Anthony Baxterc51ee692006-04-01 00:57:31 +00001321- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001322 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001323 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001324 module will not be built.
1325
Tim Petersc17976e2006-04-01 00:26:53 +00001326- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1327 aren't officially supported here, and trying to use them will probably
1328 raise an exception some day. But dicts have been allowed, and "mostly
1329 worked", so support for them won't go away without warning.
1330
Georg Brandl338ef7d2006-03-31 18:42:16 +00001331- Bug #1445068: getpass.getpass() can now be given an explicit stream
1332 argument to specify where to write the prompt.
1333
Georg Brandl22ec80b2006-03-31 18:25:44 +00001334- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1341
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001342- Queue.Queue objects now support .task_done() and .join() methods
1343 to make it easier to monitor when daemon threads have completed
1344 processing all enqueued tasks. Patch #1455676.
1345
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001346- popen2.Popen objects now preserve the command in a .cmd attribute.

1349
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001350- email 4.0 package now integrated. This is largely the same as the email 3.0
1351 package that was included in Python 2.3, except that PEP 8 module names are
1352 now used (e.g. mail.message instead of email.Message). The MIME classes
1353 have been moved to a subpackage (e.g. email.mime.text instead of
1354 email.MIMEText). The old names are still supported for now. Several
1355 deprecated Message methods have been removed and lots of bugs have been
1356 fixed. More details can be found in the email package documentation.
1357
Walter Dörwald40108c92006-03-27 08:15:44 +00001358- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1359 (a subclass of tuple) that provides incremental decoders and encoders
1360 (a way to use stateful codecs without the stream API). Python functions
1361 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1362 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1363 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001364
Walter Dörwald067db482006-03-15 22:17:27 +00001365- Patch #1359365: Calling next() on a closed StringIO.String object raises
1366 a ValueError instead of a StopIteration now (like file and cString.String do).
1367 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1368 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001369
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001370- A regrtest option -w was added to re-run failed tests in verbose mode.

1376 grew an optional 'generation' argument.
1377
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00001378- A library msilib to generate Windows Installer files, and a distutils

1380
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001381- PEP 343: new module contextlib.py defines decorator @contextmanager
1382 and helpful context managers nested() and closing().
1383

Martin v. Löwis3e865952006-01-24 15:51:21 +00001418 specifications, raises IOErrors when proxies for unsupported protocols
1419 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00001442 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1443 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1444 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1445 Ronald L. Rivest offered this advice for Python:
1446
1447 "The consensus of researchers in this area (at least as
1448 expressed at the NIST Hash Function Workshop 10/31/05),
1449 is that SHA-256 is a good choice for the time being, but
1450 that research should continue, and other alternatives may
1451 arise from this research. The larger SHA's also seem OK."

1506 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001507 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001508

1530 to W3C name (404 -> 'Not Found'). RFE #1216944.
1531
Georg Brandl9e43acf2005-07-04 17:16:07 +00001532- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1533 as this can cause problems with apps closing all file descriptors.

Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001545- The tokenize module now detects and reports indentation errors.
1546 Bug #1224621.
1547
Raymond Hettinger68c04532005-06-10 11:05:19 +00001548- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001549 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001550 the generate_tokens() function now accepts a callable argument that
1551 terminates by raising StopIteration.
1552
Georg Brandl9166e1a2005-06-04 09:20:03 +00001553- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1554

1557
Skip Montanaro174dd222005-05-14 20:54:16 +00001558- Patch #1120353: The xmlrpclib module provides better, more transparent,

1560 to True, applications shouldn't have to fiddle with the DateTime wrapper
1561 class at all.
1562
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001563- distutils.commands.upload was added to support uploading distribution

1565
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001566- distutils.commands.register now encodes the data as UTF-8 before posting
1567 them to PyPI.
1568
Raymond Hettinger267b8682005-03-27 10:47:39 +00001569- decimal operator and comparison methods now return NotImplemented
1570 instead of raising a TypeError when interacting with other types. This
1571 allows other classes to implement __radd__ style methods and have them
1572 work as expected.
1573
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001574- Bug #1163325: Decimal infinities failed to hash. Attempting to
1575 hash a NaN raised an InvalidOperation instead of a TypeError.
1576
Tim Petersecc6e6a2005-07-10 22:30:55 +00001577- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001578 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1579

1611
Guido van Rossumd0641422005-02-03 15:01:24 +00001612- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1613 disables recursive traversal through instance attributes, which can
1614 be exploited in various ways.
1615
Tim Peterse3547fd2005-12-16 23:13:57 +00001616- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001617 flags on the HTTP listening socket.
1618
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001619- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1620 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1621
Tim Peterse3547fd2005-12-16 23:13:57 +00001622- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001623 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1624
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001625- Bug #1110478: Revert os.environ.update to do putenv again.
1626
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001627- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1628
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001629- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1630
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001631- Enhancements to the csv module:
1632
1633 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001634 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001635 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001636 + Dialect parameter parsing has been re-implemented to improve error
1637 reporting.
1638 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1639 dictates.
1640 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001641 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001642 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001643 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1644 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001645 + reader now allows \r characters to be quoted (previously it only allowed
1646 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001647 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001648 + Dialect classes passed to the module are no longer instantiated by
1649 the module before being parsed (the former validation scheme required
1650 this, but the mechanism was unreliable).
1651 + The dialect registry now contains instances of the internal
1652 C-coded dialect type, rather than references to python objects.
1653 + the internal c-coded dialect type is now immutable.
1654 + register_dialect now accepts the same keyword dialect specifications
1655 as the reader and writer, allowing the user to register dialects
1656 without first creating a dialect class.
1657 + a configurable limit to the size of parsed fields has been added -
1658 previously, an unmatched quote character could result in the entire
1659 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001660 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001661 the parser field size limit (returning the former limit). The initial
1662 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001663 + A line_num attribute has been added to the reader object, which tracks
1664 the number of lines read from the source iterator. This is not
1665 the same as the number of records returned, as records can span
1666 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001667 + reader and writer objects were not being registered with the cyclic-GC.
1668 This has been fixed.
1669
Brett Cannone6539c42005-01-08 02:43:53 +00001670- _DummyThread objects in the threading module now delete self.__block that is
1671 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1672 lock primitives tend to be limited in number and thus should not be wasted on
1673 a _DummyThread object. Fixes bug #1089632.
1674
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001675- The imghdr module now detects Exif files.
1676
Raymond Hettinger6065d322004-12-20 23:51:53 +00001677- StringIO.truncate() now correctly adjusts the size attribute.
1678 (Bug #951915).
1679
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001680- locale.py now uses an updated locale alias table (built using
1681 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1682 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001683 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001684
Raymond Hettinger3557f422004-12-07 12:02:02 +00001685- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1686
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001687- the pickle module no longer accepts the deprecated None option in the
1688 args tuple returned by __reduce__().
1689
Brett Cannon84667c02004-12-07 03:25:18 +00001690- optparse now optionally imports gettext. This allows its use in setup.py.
1691
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001692- the pickle module no longer uses the deprecated bin parameter.
1693
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001694- the shelve module no longer uses the deprecated binary parameter.
1695
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001696- the pstats module no longer uses the deprecated ignore() method.
1697
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001698- the filecmp module no longer uses the deprecated use_statcache argument.
1699
Raymond Hettinger664347b2004-12-04 21:21:53 +00001700- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1701 extended or overridden by subclasses. Formerly, the subclassed method would
1702 be ignored by the rest of the module. (Bug #1078905).
1703
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001704- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001705 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001706
Walter Dörwald36733692004-12-22 12:50:50 +00001707- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1708 once when a size argument is given. This prevents a buffer overflow in the
1709 tokenizer with very long source lines.

Barry Warsaw538561e2006-01-01 21:48:54 +00001711- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1712 immediately after creating the object, without any intervening
1713 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001714
Skip Montanaro05885812005-01-16 20:48:27 +00001715- The reconvert.quote function can now emit triple-quoted strings. The
1716 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001717
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001718- ``UserString.MutableString`` now supports negative indices in
1719 ``__setitem__`` and ``__delitem__``
1720
Greg Ward40407942005-03-05 02:53:17 +00001721- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1722 correctly.
1723
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001724- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1725 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1726 character even if the user has passed a size parameter to get a proper
1727 line ending. Remove the special handling of a "\r\n" that has been split
1728 between two lines.
1729
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001730- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1731 about illegal code points. The codec now supports PEP 293 style error
1732 handlers.
1733
Walter Dörwald78a78b02005-09-01 12:04:29 +00001734- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001735 from the input stream, so that the output is a byte string in the correct
1736 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001737
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001738- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1739 considering it exactly like a '*'.
1740
Walter Dörwald007f8df2005-10-09 19:42:27 +00001741- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1742 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001743
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001744- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1745

1747 touch the recursion limit.
1748
Walter Dörwald58917a62006-03-31 15:26:22 +00001749- Bug #947906: An object oriented interface has been added to the calendar
1750 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001751 called as a script (e.g. via ``python -mcalendar``). Localized month and
1752 weekday names can be ouput (even if an exotic encoding is used) using
1753 special classes that use unicode.

1757
Neal Norwitz602d3392006-03-31 08:21:40 +00001758- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1759 by using -mieee gcc option.
1760

1762
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001763- Build support for Win64-AMD64 was added.
1764
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001765- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1766
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001767- Patch #881820: look for openpty and forkpty also in libbsd.
1768
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001769- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1770 The zlib module is now builtin on Windows.
1771
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001772- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1773
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001774- Bug #1189330: configure did not correctly determine the necessary
1775 value of LINKCC if python was built with GCC 4.0.
1776
Trent Mick8321b422005-07-26 02:29:21 +00001777- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1778 vulnerability in zlib 1.2.1 and 1.2.2.
1779
Brett Cannon08cd5982005-04-24 22:26:38 +00001780- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1781 flags that change binary compatibility. Changes were also made to
1782 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001783 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001784
Bob Ippolitoed233462005-03-29 13:47:59 +00001785- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1786 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1787 no longer exists). This configure patch makes things right.
1788
Martin v. Löwise2713be2005-03-08 15:03:08 +00001789- Bug #1158607: Build with --disable-unicode again.
1790
Brett Cannon46d96232005-02-16 00:07:19 +00001791- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1792 defined. Discovered as a result of not being able to build on OS X.
1793
Brett Cannon516592f2004-12-07 00:42:59 +00001794- setup.py now uses the directories specified in LDFLAGS using the -L option
1795 and in CPPFLAGS using the -I option for adding library and include
1796 directories, respectively, for compiling extension modules against. This has
1797 led to the core being compiled using the values in CPPFLAGS. It also removes
1798 the need for the special-casing of both DarwinPorts and Fink for darwin since
1799 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1800 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1801 Fink, ``-I/opt/local/include`` for DarwinPorts).
1802
Brett Cannon43802422005-02-10 20:48:03 +00001803- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1804 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1805 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1806 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001808C API
1809-----
1810
Tim Petersc9d78aa2006-03-26 23:27:58 +00001811- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1812 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1813 is obtained via the ``PyObject_`` family, it must be released via the
1814 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1815 always been officially true, but when Python's small-object allocator was
1816 introduced, an attempt was made to cater to a few extension modules
1817 discovered at the time that obtained memory via ``PyObject_New`` but
1818 released it via ``PyMem_DEL``. It's years later, and if such code still
1819 exists it will fail now (probably with segfaults, but calling wrong
1820 low-level memory management functions can yield many symptoms).
1821
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001822- Added a C API for set and frozenset objects.
1823
Raymond Hettinger66517482004-12-03 11:45:13 +00001824- Removed PyRange_New().
1825
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001826- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1827 mapping argument now. This string is used as a mapping table. Byte values
1828 greater than the length of the string and 0xFFFE are treated as undefined
1829 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00001835- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001836
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001837- Patch #1276356: New resource "urlfetch" is implemented. This enables
1838 even impatient people to run tests that require remote files.
