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.

48-------
49
Martin v. Löwis997ceff2006-07-27 06:38:16 +000050- The distutils version has been changed to 2.5.0.
51
Martin v. Löwis9298eff2006-07-26 12:12:56 +000052- Bug #978833: Really close underlying socket in _socketobject.close.
53
Georg Brandl0619a322006-07-26 07:40:17 +000054- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
55 with title().
56
Georg Brandlcf0c1722006-07-26 07:23:32 +000057- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
58 to recursive calls and call it with the failing package name.
59
Martin v. Löwis0b483032006-07-25 09:53:12 +000060- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
61
Georg Brandlc13c34c2006-07-24 14:09:56 +000062- Patch #1515343: Fix printing of deprecated string exceptions with a
63 value in the traceback module.
64
Greg Ward48fae7a2006-07-23 16:05:51 +000065- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
66
Martin v. Löwis426f4a12006-07-18 17:46:31 +000067- Patch #1524429: Use repr() instead of backticks in Tkinter again.
68
Brett Cannoncaebe222006-07-18 04:41:36 +000069- Bug #1520914: Change time.strftime() to accept a zero for any position in its
70 argument tuple. For arguments where zero is illegal, the value is forced to
71 the minimum value that is correct. This is to support an undocumented but
72 common way people used to fill in inconsequential information in the time
73 tuple pre-2.4.
74
Bob Ippolito5ea4bf12006-07-15 16:53:15 +000075- Patch #1220874: Update the binhex module for Mach-O.
76
Barry Warsawb110bad2006-07-21 14:51:07 +000077- The email package has improved RFC 2231 support, specifically for
78 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
79 (name*0=<blah>) parameter continuations. This may change the types of
80 values returned from email.message.Message.get_param() and friends.
81 Specifically in some cases where non-encoded continuations were used,
82 get_param() used to return a 3-tuple of (None, None, string) whereas now it
83 will just return the string (since non-encoded continuations don't have
84 charset and language parts).
85
86 Also, whereas % values were decoded in all parameter continuations, they are
87 now only decoded in encoded parameter parts.
88
Ronald Oussoren3075e162006-07-25 20:28:55 +000089- Bug #1517990: IDLE keybindings on MacOS X now work correctly
90
91- Bug #1517996: IDLE now longer shows the default Tk menu when a
92 path browser, class browser or debugger is the frontmost window on MacOS X

96-----------------
97
Tim Petersbc24eee2006-07-27 01:14:53 +000098- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +000099 Paul Eggert.
100
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000101- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
102
Thomas Hellerce049a02006-07-14 17:51:14 +0000103- Patch #1521817: Index range checking on ctypes arrays containing
104 exactly one element enabled again. This allows iterating over these
105 arrays, without the need to check the array size before.
106
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000107- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000108 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000109 /dev/null in certain cases; this is now fixed.
110
Thomas Heller47d7a062006-07-12 08:43:47 +0000111- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
112 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000113
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000114- Because of a misspelled preprocessor symbol, ctypes was always
115 compiled without thread support; this is now fixed.
116
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000117Tests
118-----
119
120- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
121 how long the test file should take to play. Now accepts taking 2.93 secs
122 (exact time) +/- 10% instead of the hard-coded 3.1 sec.

130Core and builtins
131-----------------
132
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000133- Bug #1441486: The literal representation of -(sys.maxint - 1)
134 again evaluates to a int object, not a long.
135
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000136- Bug #1501934: The scope of global variables that are locally assigned
137 using augmented assignment is now correctly determined.
138
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000139- Bug #927248: Recursive method-wrapper objects can now safely
140 be released.
141
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000142- Bug #1417699: Reject locale-specific decimal point in float()
143 and atof().
144
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000145- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
146 omit a default "error" argument for NULL pointer. This allows
147 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000148
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000149- Bug #1519018: 'as' is now validated properly in import statements.
150
Neal Norwitz28746ab2006-07-09 22:14:42 +0000151- On 64 bit systems, int literals that use less than 64 bits are
152 now ints rather than longs.
153
Neal Norwitzed657552006-07-10 00:04:44 +0000154- Bug #1512814, Fix incorrect lineno's when code at module scope
155 started after line 256.
156
Tim Peters32a83612006-07-10 21:08:24 +0000157- New function ``sys._current_frames()`` returns a dict mapping thread
158 id to topmost thread stack frame. This is for expert use, and is
159 especially useful for debugging application deadlocks. The functionality
160 was previously available in Fazal Majid's ``threadframe`` extension
161 module, but it wasn't possible to do this in a wholly threadsafe way from
162 an extension.

Martin v. Löwis8d656812006-07-10 07:23:48 +0000170 environment variable to be set in order to the SDK environment
171 for finding the compiler, include files, etc.
172

176
Thomas Woutersadd19112006-07-05 11:03:49 +0000177- string.Template() now correctly handles tuple-values. Previously,
178 multi-value tuples would raise an exception and single-value tuples would
179 be treated as the value they contain, instead.
180
Martin v. Löwisede77f52006-07-03 13:01:35 +0000181- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
182 even if some data are received.
183
Martin v. Löwis45482392006-07-03 12:28:58 +0000184- Bug #1267547: Put proper recursive setup.py call into the
185 spec file generated by bdist_rpm.

Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000192
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000193- Bug #1514703: Only setup canvas window in turtle when the canvas
194 is created.
195
Martin v. Löwis7596e832006-07-01 15:33:37 +0000196- Bug #1513223: .close() of a _socketobj now releases the underlying

206
Brett Cannon53ab5b72006-06-22 16:49:14 +0000207- Bug #1510580: The 'warnings' module improperly required that a Warning
208 category be either a types.ClassType and a subclass of Warning. The proper
209 check is just that it is a subclass with Warning as the documentation states.
210
Georg Brandlad29e632006-06-21 17:45:17 +0000211- The compiler module now correctly compiles the new try-except-finally
212 statement (bug #1509132).
213
Neal Norwitz60373cd2006-06-22 06:30:50 +0000214- The wsgiref package is now installed properly on Unix.
215

217 shutdown when fileConfig() was called multiple times.
218
Gerhard Häring762fbd32006-07-02 17:48:30 +0000219- The sqlite3 module did cut off data from the SQLite database at the first
220 null character before sending it to a custom converter. This has been fixed
221 now.
222
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000223Extension Modules
224-----------------
225
Tim Peters112aad32006-07-19 00:03:19 +0000226- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
227 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
228 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000229
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000230- Assigning None to pointer type fields in ctypes structures possible
231 overwrote the wrong fields, this is fixed now.
232
233- Fixed a segfault in _ctypes when ctypes.wintypes were imported
234 on non-Windows platforms.
235
236- Bug #1518190: The ctypes.c_void_p constructor now accepts any
237 integer or long, without range checking.
238
239- Patch #1517790: It is now possible to use custom objects in the ctypes
240 foreign function argtypes sequence as long as they provide a from_param
241 method, no longer is it required that the object is a ctypes type.
242
243- The '_ctypes' extension module now works when Python is configured
244 with the --without-threads option.
245
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000246- Bug #1513646: os.access on Windows now correctly determines write

261
Tim Peters32a83612006-07-10 21:08:24 +0000262- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000263 Previously, the slight difference could cause compilation errors of the
264 'zlib' module on systems with more than one version of zlib.
265
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000266- The MSI compileall step was fixed to also support a TARGETDIR

312 attribute on objects until one without one is found. This leads to recursion
313 when you take a class and set its __call__ attribute to an instance of the
314 class. Originally fixed for classic classes, but this fix is for new-style.
315 Removes the infinite_rec_3 crasher.
316
Georg Brandl24250812006-06-09 18:45:48 +0000317- The string and unicode methods startswith() and endswith() now accept
318 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
319
Brett Cannonde3b0522006-06-08 17:00:45 +0000320- Buffer objects, at the C level, never used the char buffer
321 implementation even when the char buffer for the wrapped object was
322 explicitly requested (originally returned the read or write buffer).
323 Now a TypeError is raised if the char buffer is not present but is
324 requested.
325
Georg Brandlddbaa662006-06-04 21:56:52 +0000326- Patch #1346214: Statements like "if 0: suite" are now again optimized
327 away like they were in Python 2.4.
328
Georg Brandlb7c8f542006-05-27 12:30:25 +0000329- Builtin exceptions are now full-blown new-style classes instead of
330 instances pretending to be classes, which speeds up exception handling
331 by about 80% in comparison to 2.5a2.
332
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000333- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
334 Unicode 4.1.
335
Georg Brandlf4ef1162006-05-26 18:03:31 +0000336- Patch #921466: sys.path_importer_cache is now used to cache valid and
337 invalid file paths for the built-in import machinery which leads to
338 fewer open calls on startup.
339
Tim Peters696cf432006-05-24 21:10:40 +0000340- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
341 of-2 bases. The largest speedup is for inputs with about 1000 decimal
342 digits. Conversion from non-power-of-2 bases remains quadratic-time in
343 the number of input digits (it was and remains linear-time for bases
344 2, 4, 8, 16 and 32).
345
Tim Petersb713ec22006-05-23 18:45:30 +0000346- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
347 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
348 an integer close to ``sys.maxint``. This was repaired by patch
349 #1335972, which also gives a nice speedup.
350
Richard Jonescebbefc2006-05-23 18:28:17 +0000351- Patch #1337051: reduced size of frame objects.
352
353- PyErr_NewException now accepts a tuple of base classes as its
354 "base" parameter.
355
Richard Jones7c88dcc2006-05-23 10:37:38 +0000356- Patch #876206: function call speedup by retaining allocated frame
357 objects.
358
Georg Brandl7b90e162006-05-18 07:01:27 +0000359- Bug #1462152: file() now checks more thoroughly for invalid mode
360 strings and removes a possible "U" before passing the mode to the
361 C library function.
362
Neal Norwitz1004a532006-05-15 07:17:23 +0000363- Patch #1488312, Fix memory alignment problem on SPARC in unicode
364
Neal Norwitz373f0a72006-05-15 07:04:36 +0000365- Bug #1487966: Fix SystemError with conditional expression in assignment
366
Martin v. Löwis879768d2006-05-11 13:28:43 +0000367- WindowsError now has two error code attributes: errno, which carries
368 the error values from errno.h, and winerror, which carries the error
369 values from winerror.h. Previous versions put the winerror.h values
370 (from GetLastError()) into the errno attribute.
371
Martin v. Löwis77736712006-05-04 05:51:03 +0000372- Patch #1475845: Raise IndentationError for unexpected indent.
373
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000374- Patch #1479181: split open() and file() from being aliases for each other.
375
Tim Peters44bd9862006-06-01 13:49:23 +0000376- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
377 methods were always silently ignored by dictionaries when comparing keys.
378 They are now passed through (except when using the C API function
379 ``PyDict_GetItem()``, whose semantics did not change).
380
381- Bug #1456209: In some obscure cases it was possible for a class with a
382 custom ``__eq__()`` method to confuse dict internals when class instances
383 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
384 No, you don't have any code that did this ;-)

387-----------------
388
Trent Mick960a3f82006-06-28 20:30:41 +0000389- Bug #1295808: expat symbols should be namespaced in pyexpat
390
391- Patch #1462338: Upgrade pyexpat to expat 2.0.0
392
Brett Cannon6ee7d012006-06-08 16:23:04 +0000393- Change binascii.hexlify to accept a read-only buffer instead of only a char
394 buffer and actually follow its documentation.
395
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000396- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
397
Nick Coghlanc649ec52006-05-29 12:43:05 +0000398- Patch #1478788 (modified version): The functional extension module has
399 been renamed to _functools and a functools Python wrapper module added.
400 This provides a home for additional function related utilities that are
401 not specifically about functional programming. See PEP 309.
402
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000403- Patch #1493701: performance enhancements for struct module.
404
Georg Brandl378d5922006-05-17 14:26:50 +0000405- Patch #1490224: time.altzone is now set correctly on Cygwin.
406
Georg Brandl8d3342b2006-05-16 07:38:27 +0000407- Patch #1435422: zlib's compress and decompress objects now have a
408 copy() method.
409
Andrew MacIntyre92913322006-06-13 15:04:24 +0000410- Patch #1454481: thread stack size is now tunable at runtime for thread
411 enabled builds on Windows and systems with Posix threads support.
412
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000413- On Win32, os.listdir now supports arbitrarily-long Unicode path names
414 (up to the system limit of 32K characters).
415
416- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
417 As a result, these functions now raise WindowsError instead of OSError.
418
Tim Peters7a822da2006-05-25 21:50:17 +0000419- ``time.clock()`` on Win64 should use the high-performance Windows
420 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
421 Windows platforms).
422
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000423- Calling Tk_Init twice is refused if the first call failed as that
424 may deadlock.
425
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000426- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
427 accept it without potentially using an uninitialized pointer.
428
429- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
430 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
431 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000432
Gregory P. Smith372b5832006-06-05 18:48:21 +0000433- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000434 [pybsddb project SF patch number 1466734]
435
Gregory P. Smith372b5832006-06-05 18:48:21 +0000436- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
437 parameter is supplied. [SF pybsddb bug #1477863]
438
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000439- bsddb: the __len__ method of a DB object has been fixed to return correct
440 results. It could previously incorrectly return 0 in some cases.
441 Fixes SF bug 1493322 (pybsddb bug 1184012).
442
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000443- bsddb: the bsddb.dbtables Modify method now raises the proper error and
444 aborts the db transaction safely when a modifier callback fails.
445 Fixes SF python patch/bug #1408584.
446
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000447- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000448 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000449 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
450 database calls that would previously deadlock. [SF python bug #775414]
451
Vinay Sajip28e57612006-07-01 10:45:20 +0000452- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000453
Walter Dörwald4994d952006-06-19 08:07:50 +0000454- Patch #1506645: add Python wrappers for the curses functions
455 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000456

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000460- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
461 functions.
462
Martin v. Löwis3798da02006-06-17 18:44:27 +0000463- Patch #812986: Update turtle output even if not tracing.
464
Vinay Sajip28e57612006-07-01 10:45:20 +0000465- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000466 Tkinter.BaseWidget.
467
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000468- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
469
Martin v. Löwis337487e2006-06-17 09:15:14 +0000470- Patch #763580: Add name and value arguments to Tkinter variable
471 classes.
472
Georg Brandl83cc0d02006-06-14 08:50:03 +0000473- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
474 mime.types file for determining MIME types.
475
Georg Brandl2605ca82006-06-14 06:08:31 +0000476- Bug #1339007: Shelf objects now don't raise an exception in their
477 __del__ method when initialization failed.
478
Martin v. Löwisd8251432006-06-14 05:21:04 +0000479- Patch #1455898: The MBCS codec now supports the incremental mode for
480 double-byte encodings.
481
Tim Peters43898b42006-06-14 04:09:25 +0000482- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
483 guarantee that adjacent triples in the return list always describe
484 non-adjacent blocks. Previously, a pair of matching blocks could end
485 up being described by multiple adjacent triples that formed a partition
486 of the matching pair.
487
Greg Ward0e0c9f42006-06-11 16:24:11 +0000488- Bug #1498146: fix optparse to handle Unicode strings in option help,
489 description, and epilog.
490
Greg Wardd1c797e2006-06-11 14:42:41 +0000491- Bug #1366250: minor optparse documentation error.
492
Greg Ward7f547402006-06-11 00:40:49 +0000493- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
494 clarify docs.
495
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000496- The wsgiref package has been added to the standard library.
497
Nick Coghlan676725d2006-06-08 13:54:49 +0000498- The functions update_wrapper() and wraps() have been added to the functools
499 module. These make it easier to copy relevant metadata from the original
500 function when writing wrapper functions.
501
Tim Petersd6a9eef2006-06-05 01:48:21 +0000502- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
503 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000504
Martin v. Löwis3f767792006-06-04 19:36:28 +0000505- Patch #1359618: Speed up charmap encoder by using a trie structure
506 for lookup.
507
Tim Petersd609b1a2006-06-02 23:22:51 +0000508- The functions in the ``pprint`` module now sort dictionaries by key
509 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
510 if and only if its display required more than one line, although that
511 wasn't documented. The new behavior increases predictability; e.g.,
512 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
513
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000514- Patch #1497027: try HTTP digest auth before basic auth in urllib2
515 (thanks for J. J. Lee).
516
Georg Brandl2b330372006-05-28 20:23:12 +0000517- Patch #1496206: improve urllib2 handling of passwords with respect to
518 default HTTP and HTTPS ports.
519
George Yoshidaf3c65de2006-05-28 16:39:09 +0000520- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
521
Bob Ippolito7298f272006-05-23 18:43:47 +0000522- Patch #1281707: speed up gzip.readline.
523
Georg Brandlb89316f2006-05-17 15:51:16 +0000524- Patch #1180296: Two new functions were added to the locale module:
525 format_string() to get the effect of "format % items" but locale-aware,
526 and currency() to format a monetary number with currency sign.
527
Georg Brandle3a25832006-05-17 14:56:04 +0000528- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
529 and several features added, such as speed and geometry control.
530
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000531- Patch #1488881: add support for external file objects in bz2 compressed
532 tarfiles.
533
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000534- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
535 stdout arguments, making it possible to redirect input and output
536 for remote debugging.
537
538- Patch #1484695: Update the tarfile module to version 0.8. This fixes
539 a couple of issues, notably handling of long file names using the
540 GNU LONGNAME extension.
541
542- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
543 new flag when ``name`` is already the name of an option flag.
544
545- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
546 package.
547
548- Patch #1472854: make the rlcompleter.Completer class usable on non-
549 UNIX platforms.
550
551- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
552
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000553- Bug #1472827: correctly escape newlines and tabs in attribute values in

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000584What's New in Python 2.5 alpha 2?
585=================================
586
587*Release date: 27-APR-2006*
588
589Core and builtins
590-----------------
591
Thomas Heller1b046642006-04-18 18:51:06 +0000592- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
593 by converting these apis from macros into exported functions again:
594
595 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
596 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
597 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
598 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
599 PyRun_String Py_CompileString
600
Martin v. Löwis45294a92006-04-18 06:24:08 +0000601- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
602
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000603- All uses of PyStructSequence_InitType have been changed to initialize
604 the type objects only once, even if the interpreter is initialized
605 multiple times.
606
Neal Norwitz61546162006-04-14 05:20:28 +0000607- Bug #1454485, array.array('u') could crash the interpreter. This was
608 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
609 to unicode when it didn't make sense. 'u#' now requires a unicode string.
610
611- Py_UNICODE is unsigned. It was always documented as unsigned, but
612 due to a bug had a signed value in previous versions.
613
Tim Peters3a5e8b12006-04-11 01:44:07 +0000614- Patch #837242: ``id()`` of any Python object always gives a positive
615 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
616 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000617 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000618 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000619
Tim Peters3a5e8b12006-04-11 01:44:07 +0000620 def __hash__(self):
621 return id(self) # WRONG
622
623 because a hash result must be a (short) Python int but it was always
624 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000625 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000626 was always usable as a hash value before this patch. That's no longer
627 necessarily so.
628
629- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000630 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000631 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000632 #1454844)
633
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000634- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
635 involving generators that have paused outside of any ``try`` or ``with``
636 blocks. (In 2.5a1, a paused generator that was part of a reference
637 cycle could not be garbage collected, regardless of whether it was
638 paused in a ``try`` or ``with`` block.)

651- Bug #1117761: bsddb.*open() no longer raises an exception when using
652 the cachesize parameter.
653
654- Bug #1149413: bsddb.*open() no longer raises an exception when using
655 a temporary db (file=None) with the 'n' flag to truncate on open.
656
657- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
658 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000659
Armin Rigoa9017c32006-04-19 11:50:27 +0000660- Patch #1062014: AF_UNIX sockets under Linux have a special
661 abstract namespace that is now fully supported.
662
Anthony Baxter51bcb682006-04-05 14:51:42 +0000663Library
664-------
665
Peter Astrand7d1d4362006-07-14 14:04:45 +0000666- Bug #1223937: subprocess.CalledProcessError reports the exit status
667 of the process using the returncode attribute, instead of
668 abusing errno.
669
Tim Peters711bf302006-04-25 03:31:36 +0000670- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
671 a doctest to be skipped (the code is not run, and the expected output
672 or exception is ignored).
673
Nick Coghlanda2268f2006-04-24 04:37:15 +0000674- Fixed contextlib.nested to cope with exceptions being raised and
675 caught inside exit handlers.
676
Greg Wardab05edc2006-04-23 03:47:58 +0000677- Updated optparse module to Optik 1.5.1 (allow numeric constants in
678 hex, octal, or binary; add ``append_const`` action; keep going if
679 gettext cannot be imported; added ``OptionParser.destroy()`` method;
680 added ``epilog`` for better help generation).
681
Tim Peters21fbd572006-04-21 21:18:10 +0000682- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
683 called from a thread spawned as a side effect of importing a module.
684
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000685- The pydoc module now supports documenting packages contained in
686 .zip or .egg files.
687
688- The pkgutil module now has several new utility functions, such
689 as ``walk_packages()`` to support working with packages that are either
690 in the filesystem or zip files.
691
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000692- The mailbox module can now modify and delete messages from
693 mailboxes, in addition to simply reading them. Thanks to Gregory
694 K. Johnson for writing the code, and to the 2005 Google Summer of
695 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000696
Tim Petersc7605f22006-04-17 21:12:33 +0000697- The ``__del__`` method of class ``local`` in module ``_threading_local``
698 returned before accomplishing any of its intended cleanup.

Anthony Baxtere29002c2006-04-12 12:07:31 +0000706- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
707 Windows. Bug #1469163.
708
Phillip J. Eby47032112006-04-11 01:07:43 +0000709- The warnings, linecache, inspect, traceback, site, and doctest modules
710 were updated to work correctly with modules imported from zipfiles or
711 via other PEP 302 __loader__ objects.

719
Skip Montanaro262fb922006-04-21 02:31:07 +0000720- The pstats.Stats class accepts an optional stream keyword argument to
721 direct output to an alternate file-like object.
722
Anthony Baxter51bcb682006-04-05 14:51:42 +0000723Build
724-----
725
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000726- The Makefile now has a reindent target, which runs reindent.py on
727 the library.
728
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000729- Patch #1470875: Building Python with MS Free Compiler
730
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000731- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000732
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000733- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
734 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000735 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000736 CXX from --with-cxx-main, see description in README.
737
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000738- Patch #1429775: Link extension modules with the shared libpython.
739
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000740- Fixed a libffi build problem on MIPS systems.
741
Tim Peters8931ff12006-05-13 23:28:20 +0000742- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
743 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
744 and "%zu" for unsigned integers of type ``size_t``.
745
Anthony Baxter51bcb682006-04-05 14:51:42 +0000746Tests
747-----
748
Nick Coghlanda2268f2006-04-24 04:37:15 +0000749- test_contextlib now checks contextlib.nested can cope with exceptions
750 being raised and caught inside exit handlers.
751
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000752- test_cmd_line now checks operation of the -m and -c command switches
753
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000754- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
755 it separately and by hand. It also wasn't cleaning up its changes to
756 the current Decimal context.
757
Thomas Woutersabd08882006-04-26 15:53:30 +0000758- regrtest.py now has a -M option to run tests that test the new limits of
759 containers, on 64-bit architectures. Running these tests is only sensible
760 on 64-bit machines with more than two gigabytes of memory. The argument
761 passed is the maximum amount of memory for the tests to use.

770-------------
771
Tim Petersb06d28c2006-05-12 01:57:59 +0000772- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
773
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000774- PEP 343: Added Context Types section to the library reference
775 and attempted to bring other PEP 343 related documentation into
776 line with the implementation and/or python-dev discussions.
777
Tim Peters8dc73d22006-04-24 02:03:16 +0000778- Bug #1337990: clarified that ``doctest`` does not support examples
779 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000782What's New in Python 2.5 alpha 1?
783=================================
784
Anthony Baxterebed3f62006-04-03 15:03:44 +0000785*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000786
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000787Core and builtins
788-----------------
789
Nick Coghlan43832302006-04-23 17:04:07 +0000790- PEP 338: -m command line switch now delegates to runpy.run_module
791 allowing it to support modules in packages and zipfiles
792
Martin v. Löwisc661b882006-04-20 04:54:23 +0000793- On Windows, .DLL is not an accepted file name extension for
794 extension modules anymore; extensions are only found if they
795 end in .PYD.
796
Martin v. Löwisea62d252006-04-03 10:56:49 +0000797- Bug #1421664: sys.stderr.encoding is now set to the same value as
798 sys.stdout.encoding.
799
Neal Norwitz92e212f2006-04-03 04:48:37 +0000800- __import__ accepts keyword arguments.
801
Georg Brandlccadf842006-03-31 18:54:53 +0000802- Patch #1460496: round() now accepts keyword arguments.
803
Anthony Baxter262c00a2006-03-30 10:53:17 +0000804- Fixed bug #1459029 - unicode reprs were double-escaped.
805
Hye-Shik Changd478f342006-03-23 12:32:36 +0000806- Patch #1396919: The system scope threads are reenabled on FreeBSD
807 5.4 and later versions.
808
Neal Norwitze98ccf62006-03-23 05:39:47 +0000809- Bug #1115379: Compiling a Unicode string with an encoding declaration
810 now gives a SyntaxError.
811
Georg Brandlabd1ff82006-03-18 07:59:59 +0000812- Previously, Python code had no easy way to access the contents of a
813 cell object. Now, a ``cell_contents`` attribute has been added
814 (closes patch #1170323).
815
Tim Peterscf79aac2006-03-16 01:14:46 +0000816- Patch #1123430: Python's small-object allocator now returns an arena to
817 the system ``free()`` when all memory within an arena becomes unused
818 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
819 freed. Some applications will see a drop in virtual memory size now,
820 especially long-running applications that, from time to time, temporarily
821 use a large number of small objects. Note that when Python returns an
822 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000823 platform C library will in turn return that memory to the operating system.
824 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000825 appears to be effective at least on Microsoft C and gcc-based systems.
826 Thanks to Evan Jones for hard work and patience.
827
Georg Brandl533ff6f2006-03-08 18:09:27 +0000828- Patch #1434038: property() now uses the getter's docstring if there is
829 no "doc" argument given. This makes it possible to legitimately use
830 property() as a decorator to produce a read-only property.
831
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000832- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
833 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
834 of requiring an int or long in slicing and a few other contexts, enabling
835 other objects (e.g. Numeric Python's integers) to be used as slice indices.
836
Neal Norwitz995acdf2006-03-07 05:01:00 +0000837- Fixed various bugs reported by Coverity's Prevent tool.
838
Brett Cannonbf364092006-03-01 04:25:17 +0000839- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
840 new exception base class, BaseException, which has a new message attribute.
841 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
842 Raising a string exception now raises a DeprecationWarning.
843
Thomas Woutersfb609f42006-02-28 16:37:25 +0000844- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
845 explicitly relative, using 'from .module import name' to mean 'from the same
846 package as this module is in. Imports without dots still default to the
847 old relative-then-absolute, unless 'from __future__ import
848 absolute_import' is used.
849
Brett Cannona7446e32006-02-27 23:39:10 +0000850- Properly check if 'warnings' raises an exception (usually when a filter set
851 to "error" is triggered) when raising a warning for raising string
852 exceptions.
853
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000854- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000855 The name was removed from Include/code.h.
856
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000857- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000858
Guido van Rossum1968ad32006-02-25 22:38:04 +0000859- Patch 1433928:
860 - The copy module now "copies" function objects (as atomic objects).
861 - dict.__getitem__ now looks for a __missing__ hook before raising
862 KeyError.
863
Tim Peters84ef21c2006-02-28 20:39:06 +0000864- PEP 343: with statement implemented. Needs ``from __future__ import
865 with_statement``. Use of 'with' as a variable will generate a warning.
866 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000867 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000868 The following objects have __context__ methods:
869 - The built-in file type.
870 - The thread.LockType type.
871 - The following types defined by the threading module:
872 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
873 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000874
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000875- Fix the encodings package codec search function to only search
876 inside its own package. Fixes problem reported in patch #1433198.
877
878 Note: Codec packages should implement and register their own
879 codec search function. PEP 100 has the details.
880
Tim Peters9ea89d22006-06-04 03:26:02 +0000881- PEP 353: Using ``Py_ssize_t`` as the index type.
882
883- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
884 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
885 now allow Python to make use of memory blocks exceeding 2**32 bytes for
886 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
887 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000888
Neal Norwitzfc76d632006-01-10 06:03:13 +0000889- Patch #1400181, fix unicode string formatting to not use the locale.
890 This is how string objects work. u'%f' could use , instead of .
891 for the decimal point. Now both strings and unicode always use periods.
892
Neal Norwitz671b9e32006-01-09 07:07:12 +0000893- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
894 configure would break checking curses.h.
895
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000896- Bug #959576: The pwd module is now builtin. This allows Python to be
897 built on UNIX platforms without $HOME set.
898
Neal Norwitzc10978f2005-12-19 06:07:16 +0000899- Bug #1072182, fix some potential problems if characters are signed.
900
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000901- Bug #889500, fix line number on SyntaxWarning for global declarations.
902
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000903- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
904
Neal Norwitze7214a12005-12-18 05:03:17 +0000905- Support for converting hex strings to floats no longer works.
906 This was not portable. float('0x3') now raises a ValueError.
907
Barry Warsaw2a38a862005-12-18 01:27:35 +0000908- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000909 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000910 is now displayed in interactive prompt banner.
911
Georg Brandlfa166682005-12-17 21:45:17 +0000912- Implementation of PEP 341 - Unification of try/except and try/finally.
913 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000914 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000915
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000916- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
917 now encodes backslash correctly.
918
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000919- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
920
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000921- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000922 and long longs.

Neal Norwitz67715f02005-11-09 06:59:35 +0000924- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000925 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000926 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000927
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000928- Replaced most Unicode charmap codecs with new ones using the
929 new Unicode translate string feature in the builtin charmap
930 codec; the codecs were created from the mapping tables available
931 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
932 encodings now include a mapping for the Apple logo)
933
Tim Peterse3547fd2005-12-16 23:13:57 +0000934- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000935
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000936- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000937
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000938- A new AST parser implementation was completed. The abstract
939 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000940 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000941
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000942- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000943 The following code now raises a SyntaxError: foo(a = i for i in range(10))
944
Neal Norwitz708e51a2005-10-03 04:48:15 +0000945- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
946
Neal Norwitz11bd1192005-10-03 00:54:56 +0000947- SF Bug #887946: fix segfault when redirecting stdin from a directory.
948 Provide a warning when a directory is passed on the command line.
949
Neal Norwitz40d37812005-10-02 01:48:49 +0000950- Fix segfault with invalid coding.
951
952- SF bug #772896: unknown encoding results in MemoryError.
953
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000954- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000955 supported a __len__() method which evaluated to False when the iterator
956 was empty.
957
Guido van Rossum630db602005-09-20 18:49:54 +0000958- On 64-bit platforms, when __len__() returns a value that cannot be
959 represented as a C int, raise OverflowError.
960
Skip Montanarof8948ca2005-09-19 03:54:46 +0000961- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000962 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000963
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000964- SF bug #893549: parsing keyword arguments was broken with a few format
965 codes.
966
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000967- Changes donated by Elemental Security to make it work on AIX 5.3
968 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
969 bug #105470: test_pwd fails on 64bit system (Opteron).
970
Guido van Rossum539c6622005-09-14 17:49:54 +0000971- Changes donated by Elemental Security to make it work on HP-UX 11 on
972 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
973
Georg Brandl4550b8d2005-08-26 06:43:52 +0000974- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000975 (fixes bug #1119418).
976
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000977- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
978
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000979- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
980 exceptions that cause a function to exit.
981
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000982- The implementation of set() and frozenset() was revised to use its
983 own internal data structure. Memory consumption is reduced by 1/3
984 and there are modest speed-ups as well. The API is unchanged.
985
Tim Petersde7990b2005-07-17 23:45:23 +0000986- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
987
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000988- SF bug #1229429: PyObject_CallMethod failed to decrement some
989 reference counts in some error exit cases.
990
Tim Petersecc6e6a2005-07-10 22:30:55 +0000991- SF bug #1185883: Python's small-object memory allocator took over
992 a block managed by the platform C library whenever a realloc specified
993 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000994 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000995 portable way to copy data from the C-managed block into Python's
996 small-object space without risking a memory fault. Python's small-object
997 realloc now leaves such blocks under the control of the platform C
998 realloc.
999
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001000- SF bug #1232517: An overflow error was not detected properly when
1001 attempting to convert a large float to an int in os.utime().
1002
Raymond Hettinger3296e692005-06-29 23:29:56 +00001003- SF bug #1224347: hex longs now print with lowercase letters just
1004 like their int counterparts.
1005
Michael W. Hudson188d4362005-06-20 16:52:57 +00001006- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1007 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1008 interpreter states; back out that fix and do a better job (see
1009 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1010 for a longer write-up of the problem).
1011
Michael W. Hudsondf888462005-06-03 14:41:55 +00001012- SF patch #1180995: marshal now uses a binary format by default when
1013 serializing floats.
1014
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001015- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1016 the routines that promise to produce IEEE 754 binary representations
1017 of floats now simply copy bytes around.
1018
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001019- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1020 278.
1021
Brett Cannonc3647ac2005-04-26 03:45:26 +00001022- patch #1109424: int, long, float, complex, and unicode now check for the
1023 proper magic slot for type conversions when subclassed. Previously the
1024 magic slot was ignored during conversion. Semantics now match the way
1025 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001026 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001027 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001028 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001029
Barry Warsawc8d907c2005-04-19 23:43:40 +00001030- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1031 NULL, now raise an AttributeError when attempting to set or delete the
1032 attribute. Previously a TypeError was raised, but this was inconsistent
1033 with the equivalent pure-Python implementation.
1034
Michael W. Hudson774479c2005-04-18 08:46:17 +00001035- It is now safe to call PyGILState_Release() before
1036 PyEval_InitThreads() (note that if there is reason to believe there
1037 are multiple threads around you still must call PyEval_InitThreads()
1038 before using the Python API; this fix is for extension modules that
1039 have no way of knowing if Python is multi-threaded yet).
1040
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001041- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1042 disabled caused a crash.
1043
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001044- Bug #1165306: instancemethod_new allowed the creation of a method
1045 with im_class == im_self == NULL, which caused a crash when called.
1046
Tim Petersecc6e6a2005-07-10 22:30:55 +00001047- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001048 fixes the crash seen in bug #1165761
1049
Raymond Hettinger96229b12005-03-11 06:49:40 +00001050- Added two new builtins, any() and all().
1051
Brett Cannon409d8f22005-03-05 06:47:57 +00001052- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001053 (e.g., ``class C(): pass`` is no longer a syntax error).
1054 Patch #1176012 added support to the 'parser' module and 'compiler' package
1055 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001056
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001057- Patch #1115086: Support PY_LONGLONG in structmember.
1058
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001059- Bug #1155938: new style classes did not check that __init__() was
1060 returning None.
1061
Tim Petersecc6e6a2005-07-10 22:30:55 +00001062- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001063 ('\') with a specific error message.
1064
Martin v. Löwisff232d72005-03-03 09:24:38 +00001065- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1066
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001067- Bug #1124295: the __name__ attribute of file objects was
1068 inadvertently made inaccessible in restricted mode.
1069
Tim Petersecc6e6a2005-07-10 22:30:55 +00001070- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001071 an ferror() call.
1072
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001073- min() and max() now support key= arguments with the same meaning as in
1074 list.sort().
1075
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001076- The peephole optimizer now performs simple constant folding in expressions:
1077 (2+3) --> (5).
1078
Raymond Hettingera422c342005-01-11 03:03:27 +00001079- set and frozenset objects can now be marshalled. SF #1098985.
1080
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001081- Bug #1077106: Poor argument checking could cause memory corruption
1082 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001083
Jeremy Hyltonab630502005-02-04 18:44:06 +00001084- The parser did not complain about future statements in illegal
1085 positions. It once again reports a syntax error if a future
1086 statement occurs after anything other than a doc string.
1087
Neil Schemenauercf52c072005-08-12 17:34:58 +00001088- Change the %s format specifier for str objects so that it returns a
1089 unicode instance if the argument is not an instance of basestring and
1090 calling __str__ on the argument returns a unicode instance.
1091
Tim Petersf4e69282006-02-27 17:15:31 +00001092- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1093 current thread state when the auto-GIL-state machinery knows about
1094 it (since the thread state is being deleted, continuing to remember it
1095 can't help, but can hurt if another thread happens to get created with
1096 the same thread id).
1097
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001098Extension Modules
1099-----------------
1100

Neal Norwitz10be10c2006-03-16 06:50:13 +00001114 util, whatsound, whrandom, zmod
1115
1116- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1117
1118- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001119 is deprecated. The undocumented re.engine variable no longer exists.
1120
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001121- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1122 SS2 (single-shift 2) escape sequences correctly.
1123
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001124- The unicodedata module was updated to the 4.1 version of the Unicode
1125 database. The 3.2 version is still available as unicodedata.db_3_2_0
1126 for applications that require this specific version (such as IDNA).
1127
Neal Norwitzb62c4332006-03-04 18:35:47 +00001128- The timing module is no longer built by default. It was deprecated
1129 in PEP 4 in Python 2.0 or earlier.
1130
Guido van Rossum1968ad32006-02-25 22:38:04 +00001131- Patch 1433928: Added a new type, defaultdict, to the collections module.
1132 This uses the new __missing__ hook behavior added to dict (see above).
1133
Georg Brandldbd83392006-02-20 09:42:33 +00001134- Bug #854823: socketmodule now builds on Sun platforms even when
1135 INET_ADDRSTRLEN is not defined.
1136
Georg Brandlf4f44152006-02-18 22:29:33 +00001137- Patch #1393157: os.startfile() now has an optional argument to specify
1138 a "command verb" to invoke on the file.
1139
Neal Norwitz082b2df2006-02-07 07:04:46 +00001140- Bug #876637, prevent stack corruption when socket descriptor
1141 is larger than FD_SETSIZE.
1142
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001143- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1144 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1145 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1146
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001147- Patch #1422385: The nis module now supports access to domains other
1148 than the system default domain.
1149
Martin v. Löwis14694662006-02-03 12:54:16 +00001150- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1151 are reported, the limit on path name lengths is removed, and stat reports
1152 WindowsError now (instead of OSError).
1153
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001154- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

1229 the request code argument, which results in more C-like behaviour
1230 for large or negative values.
1231
Tim Petersecc6e6a2005-07-10 22:30:55 +00001232- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

1247
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00001248- operator.itemgetter() and operator.attrgetter() now support retrieving

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001272- the cPickle module no longer accepts the deprecated None option in the
1273 args tuple returned by __reduce__().
1274
Raymond Hettingerb2594052004-12-05 09:25:51 +00001275- itertools.islice() now accepts None for the start and step arguments.

1277 islice(s.start, s.stop, s.step)
1278
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001279- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001288- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1289 been renamed to have only a single underscore prefix. This was done to
1290 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001291
Nick Coghlan43832302006-04-23 17:04:07 +00001292- PEP 338: new module runpy defines a run_module function to support
1293 executing modules which provide access to source code or a code object
1294 via the PEP 302 import mechanisms.
1295
Anthony Baxter93f5b932006-04-03 08:05:07 +00001296- The email module's parsedate_tz function now sets the daylight savings
1297 flag to -1 (unknown) since it can't tell from the date whether it should

1304 in attribute values.
1305
Anthony Baxterc51ee692006-04-01 00:57:31 +00001306- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001307 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001308 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001309 module will not be built.
1310
Tim Petersc17976e2006-04-01 00:26:53 +00001311- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1312 aren't officially supported here, and trying to use them will probably
1313 raise an exception some day. But dicts have been allowed, and "mostly
1314 worked", so support for them won't go away without warning.
1315
Georg Brandl338ef7d2006-03-31 18:42:16 +00001316- Bug #1445068: getpass.getpass() can now be given an explicit stream
1317 argument to specify where to write the prompt.
1318
Georg Brandl22ec80b2006-03-31 18:25:44 +00001319- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1326
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001327- Queue.Queue objects now support .task_done() and .join() methods
1328 to make it easier to monitor when daemon threads have completed
1329 processing all enqueued tasks. Patch #1455676.
1330
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001331- popen2.Popen objects now preserve the command in a .cmd attribute.

1334
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001335- email 4.0 package now integrated. This is largely the same as the email 3.0
1336 package that was included in Python 2.3, except that PEP 8 module names are
1337 now used (e.g. mail.message instead of email.Message). The MIME classes
1338 have been moved to a subpackage (e.g. email.mime.text instead of
1339 email.MIMEText). The old names are still supported for now. Several
1340 deprecated Message methods have been removed and lots of bugs have been
1341 fixed. More details can be found in the email package documentation.
1342
Walter Dörwald40108c92006-03-27 08:15:44 +00001343- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1344 (a subclass of tuple) that provides incremental decoders and encoders
1345 (a way to use stateful codecs without the stream API). Python functions
1346 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1347 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1348 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001349
Walter Dörwald067db482006-03-15 22:17:27 +00001350- Patch #1359365: Calling next() on a closed StringIO.String object raises
1351 a ValueError instead of a StopIteration now (like file and cString.String do).
1352 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1353 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001354
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001355- A regrtest option -w was added to re-run failed tests in verbose mode.

1359
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001360- The function get_count() has been added to the gc module, and gc.collect()
1361 grew an optional 'generation' argument.
1362
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00001363- A library msilib to generate Windows Installer files, and a distutils

1365
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001366- PEP 343: new module contextlib.py defines decorator @contextmanager
1367 and helpful context managers nested() and closing().
1368
Martin v. Löwis415ed932006-02-27 19:56:30 +00001369- The compiler package now supports future imports after the module docstring.
1370

1373
Georg Brandlc98eeed2006-02-19 14:57:47 +00001374- Patch #1215184: FileInput now can be given an opening hook which can

1384 translation functions other than _() in the builtin namespace.
1385

Martin v. Löwis3e865952006-01-24 15:51:21 +00001403 specifications, raises IOErrors when proxies for unsupported protocols
1404 are defined, and uses the https proxy on https redirections.
1405
Georg Brandl531ceba2006-01-21 07:20:56 +00001406- Bug #902075: urllib2 now supports 'host:port' style proxy specifications.

Tim Peterse3547fd2005-12-16 23:13:57 +00001427 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1428 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1429 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1430 Ronald L. Rivest offered this advice for Python:
1431
1432 "The consensus of researchers in this area (at least as
1433 expressed at the NIST Hash Function Workshop 10/31/05),
1434 is that SHA-256 is a good choice for the time being, but
1435 that research should continue, and other alternatives may
1436 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001437
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001438- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl532efab2005-08-24 22:34:21 +00001483
Georg Brandlb9256022005-08-24 18:46:39 +00001484- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
1485 ContentTooShortException, when the actually downloaded size does not
1486 match the Content-Length header.

1491 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001492 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001493

1515 to W3C name (404 -> 'Not Found'). RFE #1216944.
1516
Georg Brandl9e43acf2005-07-04 17:16:07 +00001517- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1518 as this can cause problems with apps closing all file descriptors.

Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001530- The tokenize module now detects and reports indentation errors.
1531 Bug #1224621.
1532
Raymond Hettinger68c04532005-06-10 11:05:19 +00001533- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001534 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001535 the generate_tokens() function now accepts a callable argument that
1536 terminates by raising StopIteration.
1537
Georg Brandl9166e1a2005-06-04 09:20:03 +00001538- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1539
Georg Brandl268e61c2005-06-03 14:28:50 +00001540- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1541 component of the path.
1542
Skip Montanaro174dd222005-05-14 20:54:16 +00001543- Patch #1120353: The xmlrpclib module provides better, more transparent,
1544 support for datetime.{datetime,date,time} objects. With use_datetime set
1545 to True, applications shouldn't have to fiddle with the DateTime wrapper
1546 class at all.
1547
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001548- distutils.commands.upload was added to support uploading distribution
1549 files to PyPI.
1550
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001551- distutils.commands.register now encodes the data as UTF-8 before posting
1552 them to PyPI.
1553
Raymond Hettinger267b8682005-03-27 10:47:39 +00001554- decimal operator and comparison methods now return NotImplemented
1555 instead of raising a TypeError when interacting with other types. This
1556 allows other classes to implement __radd__ style methods and have them
1557 work as expected.
1558
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001559- Bug #1163325: Decimal infinities failed to hash. Attempting to
1560 hash a NaN raised an InvalidOperation instead of a TypeError.
1561
Tim Petersecc6e6a2005-07-10 22:30:55 +00001562- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001563 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1564

1575
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001576- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1577

1596
Guido van Rossumd0641422005-02-03 15:01:24 +00001597- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1598 disables recursive traversal through instance attributes, which can
1599 be exploited in various ways.
1600
Tim Peterse3547fd2005-12-16 23:13:57 +00001601- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001602 flags on the HTTP listening socket.
1603
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001604- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1605 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1606
Tim Peterse3547fd2005-12-16 23:13:57 +00001607- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001608 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1609
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001610- Bug #1110478: Revert os.environ.update to do putenv again.
1611
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001612- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1613
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001614- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1615
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001616- Enhancements to the csv module:
1617
1618 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001619 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001620 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001621 + Dialect parameter parsing has been re-implemented to improve error
1622 reporting.
1623 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1624 dictates.
1625 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001626 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001627 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001628 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1629 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001630 + reader now allows \r characters to be quoted (previously it only allowed
1631 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001632 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001633 + Dialect classes passed to the module are no longer instantiated by
1634 the module before being parsed (the former validation scheme required
1635 this, but the mechanism was unreliable).
1636 + The dialect registry now contains instances of the internal
1637 C-coded dialect type, rather than references to python objects.
1638 + the internal c-coded dialect type is now immutable.
1639 + register_dialect now accepts the same keyword dialect specifications
1640 as the reader and writer, allowing the user to register dialects
1641 without first creating a dialect class.
1642 + a configurable limit to the size of parsed fields has been added -
1643 previously, an unmatched quote character could result in the entire
1644 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001645 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001646 the parser field size limit (returning the former limit). The initial
1647 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001648 + A line_num attribute has been added to the reader object, which tracks
1649 the number of lines read from the source iterator. This is not
1650 the same as the number of records returned, as records can span
1651 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001652 + reader and writer objects were not being registered with the cyclic-GC.
1653 This has been fixed.
1654
Brett Cannone6539c42005-01-08 02:43:53 +00001655- _DummyThread objects in the threading module now delete self.__block that is
1656 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1657 lock primitives tend to be limited in number and thus should not be wasted on
1658 a _DummyThread object. Fixes bug #1089632.
1659
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001660- The imghdr module now detects Exif files.
1661
Raymond Hettinger6065d322004-12-20 23:51:53 +00001662- StringIO.truncate() now correctly adjusts the size attribute.
1663 (Bug #951915).
1664
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001665- locale.py now uses an updated locale alias table (built using
1666 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1667 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001668 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001669
Raymond Hettinger3557f422004-12-07 12:02:02 +00001670- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1671
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001672- the pickle module no longer accepts the deprecated None option in the
1673 args tuple returned by __reduce__().
1674
Brett Cannon84667c02004-12-07 03:25:18 +00001675- optparse now optionally imports gettext. This allows its use in setup.py.
1676
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001677- the pickle module no longer uses the deprecated bin parameter.
1678
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001679- the shelve module no longer uses the deprecated binary parameter.
1680
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001681- the pstats module no longer uses the deprecated ignore() method.
1682
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001683- the filecmp module no longer uses the deprecated use_statcache argument.
1684
Raymond Hettinger664347b2004-12-04 21:21:53 +00001685- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1686 extended or overridden by subclasses. Formerly, the subclassed method would
1687 be ignored by the rest of the module. (Bug #1078905).
1688
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001689- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001690 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001691
Walter Dörwald36733692004-12-22 12:50:50 +00001692- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1693 once when a size argument is given. This prevents a buffer overflow in the
1694 tokenizer with very long source lines.
1695
Barry Warsaw538561e2006-01-01 21:48:54 +00001696- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1697 immediately after creating the object, without any intervening
1698 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001699
Skip Montanaro05885812005-01-16 20:48:27 +00001700- The reconvert.quote function can now emit triple-quoted strings. The
1701 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001702
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001703- ``UserString.MutableString`` now supports negative indices in
1704 ``__setitem__`` and ``__delitem__``
1705
Greg Ward40407942005-03-05 02:53:17 +00001706- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1707 correctly.
1708
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001709- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1710 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1711 character even if the user has passed a size parameter to get a proper
1712 line ending. Remove the special handling of a "\r\n" that has been split
1713 between two lines.
1714
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001715- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1716 about illegal code points. The codec now supports PEP 293 style error
1717 handlers.
1718
Walter Dörwald78a78b02005-09-01 12:04:29 +00001719- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001720 from the input stream, so that the output is a byte string in the correct
1721 encoding instead of a unicode string.

Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001723- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1724 considering it exactly like a '*'.
1725
Walter Dörwald007f8df2005-10-09 19:42:27 +00001726- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1727 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001728
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001729- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1730
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001731- Patch #1413711: Certain patterns of differences were making difflib
1732 touch the recursion limit.
1733
Walter Dörwald58917a62006-03-31 15:26:22 +00001734- Bug #947906: An object oriented interface has been added to the calendar
1735 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001736 called as a script (e.g. via ``python -mcalendar``). Localized month and
1737 weekday names can be ouput (even if an exotic encoding is used) using
1738 special classes that use unicode.

1742
Neal Norwitz602d3392006-03-31 08:21:40 +00001743- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1744 by using -mieee gcc option.
1745

1747
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001748- Build support for Win64-AMD64 was added.
1749
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001750- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1751
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001752- Patch #881820: look for openpty and forkpty also in libbsd.
1753
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001754- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1755 The zlib module is now builtin on Windows.
1756
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001757- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1758
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001759- Bug #1189330: configure did not correctly determine the necessary
1760 value of LINKCC if python was built with GCC 4.0.
1761
Trent Mick8321b422005-07-26 02:29:21 +00001762- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1763 vulnerability in zlib 1.2.1 and 1.2.2.
1764
Brett Cannon08cd5982005-04-24 22:26:38 +00001765- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1766 flags that change binary compatibility. Changes were also made to
1767 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001768 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001769
Bob Ippolitoed233462005-03-29 13:47:59 +00001770- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1771 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1772 no longer exists). This configure patch makes things right.
1773
Martin v. Löwise2713be2005-03-08 15:03:08 +00001774- Bug #1158607: Build with --disable-unicode again.
1775
Brett Cannon46d96232005-02-16 00:07:19 +00001776- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1777 defined. Discovered as a result of not being able to build on OS X.
1778
Brett Cannon516592f2004-12-07 00:42:59 +00001779- setup.py now uses the directories specified in LDFLAGS using the -L option
1780 and in CPPFLAGS using the -I option for adding library and include
1781 directories, respectively, for compiling extension modules against. This has
1782 led to the core being compiled using the values in CPPFLAGS. It also removes
1783 the need for the special-casing of both DarwinPorts and Fink for darwin since
1784 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1785 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1786 Fink, ``-I/opt/local/include`` for DarwinPorts).
1787
Brett Cannon43802422005-02-10 20:48:03 +00001788- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1789 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1790 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1791 Closes bug #1096244. Thanks Gregory Bond.

1794-----
1795
Tim Petersc9d78aa2006-03-26 23:27:58 +00001796- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1797 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1798 is obtained via the ``PyObject_`` family, it must be released via the
1799 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1800 always been officially true, but when Python's small-object allocator was
1801 introduced, an attempt was made to cater to a few extension modules
1802 discovered at the time that obtained memory via ``PyObject_New`` but
1803 released it via ``PyMem_DEL``. It's years later, and if such code still
1804 exists it will fail now (probably with segfaults, but calling wrong
1805 low-level memory management functions can yield many symptoms).
1806
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001807- Added a C API for set and frozenset objects.
1808
Raymond Hettinger66517482004-12-03 11:45:13 +00001809- Removed PyRange_New().
1810
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001811- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1812 mapping argument now. This string is used as a mapping table. Byte values
1813 greater than the length of the string and 0xFFFE are treated as undefined
1814 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001821
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001822- Patch #1276356: New resource "urlfetch" is implemented. This enables
1823 even impatient people to run tests that require remote files.
