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
Martin v. Löwis982e9fe2006-07-24 12:54:17 +000015- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
16
Martin v. Löwisd22968a2006-07-24 11:54:53 +000017- Patch #1232023: Stop including current directory in search
18 path on Windows.
19
Neal Norwitze1fdb322006-07-21 05:32:28 +000020- Fix some potential crashes found with failmalloc.
21
Neal Norwitze7563102006-07-17 01:00:16 +000022- Fix warnings reported by Klocwork's static analysis tool.
23
Neal Norwitz84be93b2006-07-16 01:50:38 +000024- Bug #1512814, Fix incorrect lineno's when code within a function
25 had more than 255 blank lines.
26
Georg Brandl9dceedb2006-07-12 15:31:17 +000027- Patch #1521179: Python now accepts the standard options ``--help`` and
28 ``--version`` as well as ``/?`` on Windows.
29
Neal Norwitza1f10902006-07-12 07:28:29 +000030- Bug #1520864: unpacking singleton tuples in for loop (for x, in) work
31 again. Fixing this problem required changing the .pyc magic number.
32 This means that .pyc files generated before 2.5c1 will be regenerated.
33
Tim Peters112aad32006-07-19 00:03:19 +000034- Bug #1524317: Compiling Python ``--without-threads`` failed.
35 The Python core compiles again then, and, in a build without threads, the
36 new ``sys._current_frames()`` returns a dictionary with one entry,
37 mapping the faux "thread id" 0 to the current frame.
38
Ronald Oussoren3075e162006-07-25 20:28:55 +000039- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

43-------
44
Martin v. Löwis0b483032006-07-25 09:53:12 +000045- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
46
Georg Brandlc13c34c2006-07-24 14:09:56 +000047- Patch #1515343: Fix printing of deprecated string exceptions with a
48 value in the traceback module.
49
Greg Ward48fae7a2006-07-23 16:05:51 +000050- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
51
Martin v. Löwis426f4a12006-07-18 17:46:31 +000052- Patch #1524429: Use repr() instead of backticks in Tkinter again.
53
Brett Cannoncaebe222006-07-18 04:41:36 +000054- Bug #1520914: Change time.strftime() to accept a zero for any position in its
55 argument tuple. For arguments where zero is illegal, the value is forced to
56 the minimum value that is correct. This is to support an undocumented but
57 common way people used to fill in inconsequential information in the time
58 tuple pre-2.4.
59
Bob Ippolito5ea4bf12006-07-15 16:53:15 +000060- Patch #1220874: Update the binhex module for Mach-O.
61
Barry Warsawb110bad2006-07-21 14:51:07 +000062- The email package has improved RFC 2231 support, specifically for
63 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
64 (name*0=<blah>) parameter continuations. This may change the types of
65 values returned from email.message.Message.get_param() and friends.
66 Specifically in some cases where non-encoded continuations were used,
67 get_param() used to return a 3-tuple of (None, None, string) whereas now it
68 will just return the string (since non-encoded continuations don't have
69 charset and language parts).
70
71 Also, whereas % values were decoded in all parameter continuations, they are
72 now only decoded in encoded parameter parts.
73
Ronald Oussoren3075e162006-07-25 20:28:55 +000074- Bug #1517990: IDLE keybindings on MacOS X now work correctly
75
76- Bug #1517996: IDLE now longer shows the default Tk menu when a
77 path browser, class browser or debugger is the frontmost window on MacOS X
78

Neal Norwitza1f10902006-07-12 07:28:29 +000080Extension Modules
81-----------------
82
Martin v. Löwisbda0dde2006-07-24 10:26:33 +000083- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
84
Thomas Hellerce049a02006-07-14 17:51:14 +000085- Patch #1521817: Index range checking on ctypes arrays containing
86 exactly one element enabled again. This allows iterating over these
87 arrays, without the need to check the array size before.
88
Thomas Heller6e1ad2e2006-07-13 17:05:13 +000089- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +000090 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +000091 /dev/null in certain cases; this is now fixed.
92
Thomas Heller47d7a062006-07-12 08:43:47 +000093- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
94 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +000095
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +000096- Because of a misspelled preprocessor symbol, ctypes was always
97 compiled without thread support; this is now fixed.
98
Brett Cannonf23ad3d2006-07-25 17:32:20 +000099Tests
100-----
101
102- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
103 how long the test file should take to play. Now accepts taking 2.93 secs
104 (exact time) +/- 10% instead of the hard-coded 3.1 sec.

112Core and builtins
113-----------------
114
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000115- Bug #1441486: The literal representation of -(sys.maxint - 1)
116 again evaluates to a int object, not a long.
117
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000118- Bug #1501934: The scope of global variables that are locally assigned
119 using augmented assignment is now correctly determined.
120
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000121- Bug #927248: Recursive method-wrapper objects can now safely
122 be released.
123
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000124- Bug #1417699: Reject locale-specific decimal point in float()
125 and atof().
126
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000127- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
128 omit a default "error" argument for NULL pointer. This allows
129 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000130
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000131- Bug #1519018: 'as' is now validated properly in import statements.
132
Neal Norwitz28746ab2006-07-09 22:14:42 +0000133- On 64 bit systems, int literals that use less than 64 bits are
134 now ints rather than longs.
135
Neal Norwitzed657552006-07-10 00:04:44 +0000136- Bug #1512814, Fix incorrect lineno's when code at module scope
137 started after line 256.
138
Tim Peters32a83612006-07-10 21:08:24 +0000139- New function ``sys._current_frames()`` returns a dict mapping thread
140 id to topmost thread stack frame. This is for expert use, and is
141 especially useful for debugging application deadlocks. The functionality
142 was previously available in Fazal Majid's ``threadframe`` extension
143 module, but it wasn't possible to do this in a wholly threadsafe way from
144 an extension.
145
Georg Brandlad29e632006-06-21 17:45:17 +0000146Library

Martin v. Löwis8d656812006-07-10 07:23:48 +0000152 environment variable to be set in order to the SDK environment
153 for finding the compiler, include files, etc.
154
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000155- Bug #1515998: Properly generate logical ids for files in bdist_msi.
156
Nick Coghlan2d792252006-07-06 13:47:18 +0000157- warnings.py now ignores ImportWarning by default
158
Thomas Woutersadd19112006-07-05 11:03:49 +0000159- string.Template() now correctly handles tuple-values. Previously,
160 multi-value tuples would raise an exception and single-value tuples would
161 be treated as the value they contain, instead.
162
Martin v. Löwisede77f52006-07-03 13:01:35 +0000163- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
164 even if some data are received.
165
Martin v. Löwis45482392006-07-03 12:28:58 +0000166- Bug #1267547: Put proper recursive setup.py call into the

Martin v. Löwis2b88f632006-07-03 10:19:49 +0000173 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000174
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000175- Bug #1514703: Only setup canvas window in turtle when the canvas
176 is created.
177
Martin v. Löwis7596e832006-07-01 15:33:37 +0000178- Bug #1513223: .close() of a _socketobj now releases the underlying
179 socket again, which then gets closed as it becomes unreferenced.
180
Fred Drake10497c82006-06-29 02:57:48 +0000181- Bug #1504333: Make sgmllib support angle brackets in quoted
182 attribute values.
183
184- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
185 sgmllib ('[' and ']' were not accepted).
186
Georg Brandl1be63af2006-06-28 20:23:25 +0000187- Fix a bug in the turtle module's end_fill function.
188
Brett Cannon53ab5b72006-06-22 16:49:14 +0000189- Bug #1510580: The 'warnings' module improperly required that a Warning
190 category be either a types.ClassType and a subclass of Warning. The proper
191 check is just that it is a subclass with Warning as the documentation states.
192
Georg Brandlad29e632006-06-21 17:45:17 +0000193- The compiler module now correctly compiles the new try-except-finally
194 statement (bug #1509132).
195
Neal Norwitz60373cd2006-06-22 06:30:50 +0000196- The wsgiref package is now installed properly on Unix.
197
Vinay Sajip28e57612006-07-01 10:45:20 +0000198- A bug was fixed in logging.config.fileConfig() which caused a crash on
199 shutdown when fileConfig() was called multiple times.
200
Gerhard Häring762fbd32006-07-02 17:48:30 +0000201- The sqlite3 module did cut off data from the SQLite database at the first
202 null character before sending it to a custom converter. This has been fixed
203 now.
204
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000205Extension Modules
206-----------------
207
Tim Peters112aad32006-07-19 00:03:19 +0000208- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
209 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
210 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000211
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000212- Assigning None to pointer type fields in ctypes structures possible
213 overwrote the wrong fields, this is fixed now.
214
215- Fixed a segfault in _ctypes when ctypes.wintypes were imported
216 on non-Windows platforms.
217
218- Bug #1518190: The ctypes.c_void_p constructor now accepts any
219 integer or long, without range checking.
220
221- Patch #1517790: It is now possible to use custom objects in the ctypes
222 foreign function argtypes sequence as long as they provide a from_param
223 method, no longer is it required that the object is a ctypes type.
224
225- The '_ctypes' extension module now works when Python is configured
226 with the --without-threads option.
227
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000228- Bug #1513646: os.access on Windows now correctly determines write
229 access, again.
230
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000231- Bug #1512695: cPickle.loads could crash if it was interrupted with

240-----
241
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000242- Automate Windows build process for the Win64 SSL module.
243
Tim Peters32a83612006-07-10 21:08:24 +0000244- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000245 Previously, the slight difference could cause compilation errors of the
246 'zlib' module on systems with more than one version of zlib.
247
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000248- The MSI compileall step was fixed to also support a TARGETDIR

258-----
259
260- Call os.waitpid() at the end of tests that spawn child processes in order
261 to minimize resources (zombies).

Anthony Baxter51bcb682006-04-05 14:51:42 +0000277
278Core and builtins
279-----------------
280
Georg Brandla56b9152006-06-19 06:35:54 +0000281- Patch #1507676: Error messages returned by invalid abstract object operations
282 (such as iterating over an integer) have been improved and now include the
283 type of the offending object to help with debugging.
284
Brett Cannonea3912b2006-06-13 21:46:41 +0000285- Bug #992017: A classic class that defined a __coerce__() method that returned
286 its arguments swapped would infinitely recurse and segfault the interpreter.
287
Neal Norwitz909eb122006-06-12 02:13:21 +0000288- Fix the socket tests so they can be run concurrently.
289
Neal Norwitzb9845e72006-06-12 02:11:18 +0000290- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000291 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000292
Brett Cannon22565aa2006-06-09 22:31:23 +0000293- Bug #532646: object.__call__() will continue looking for the __call__
294 attribute on objects until one without one is found. This leads to recursion
295 when you take a class and set its __call__ attribute to an instance of the
296 class. Originally fixed for classic classes, but this fix is for new-style.
297 Removes the infinite_rec_3 crasher.
298
Georg Brandl24250812006-06-09 18:45:48 +0000299- The string and unicode methods startswith() and endswith() now accept
300 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
301
Brett Cannonde3b0522006-06-08 17:00:45 +0000302- Buffer objects, at the C level, never used the char buffer
303 implementation even when the char buffer for the wrapped object was
304 explicitly requested (originally returned the read or write buffer).
305 Now a TypeError is raised if the char buffer is not present but is
306 requested.
307
Georg Brandlddbaa662006-06-04 21:56:52 +0000308- Patch #1346214: Statements like "if 0: suite" are now again optimized
309 away like they were in Python 2.4.
310
Georg Brandlb7c8f542006-05-27 12:30:25 +0000311- Builtin exceptions are now full-blown new-style classes instead of
312 instances pretending to be classes, which speeds up exception handling
313 by about 80% in comparison to 2.5a2.
314
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000315- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
316 Unicode 4.1.
317
Georg Brandlf4ef1162006-05-26 18:03:31 +0000318- Patch #921466: sys.path_importer_cache is now used to cache valid and
319 invalid file paths for the built-in import machinery which leads to
320 fewer open calls on startup.
321
Tim Peters696cf432006-05-24 21:10:40 +0000322- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
323 of-2 bases. The largest speedup is for inputs with about 1000 decimal
324 digits. Conversion from non-power-of-2 bases remains quadratic-time in
325 the number of input digits (it was and remains linear-time for bases
326 2, 4, 8, 16 and 32).
327
Tim Petersb713ec22006-05-23 18:45:30 +0000328- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
329 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
330 an integer close to ``sys.maxint``. This was repaired by patch
331 #1335972, which also gives a nice speedup.
332
Richard Jonescebbefc2006-05-23 18:28:17 +0000333- Patch #1337051: reduced size of frame objects.
334
335- PyErr_NewException now accepts a tuple of base classes as its
336 "base" parameter.
337
Richard Jones7c88dcc2006-05-23 10:37:38 +0000338- Patch #876206: function call speedup by retaining allocated frame
339 objects.
340
Georg Brandl7b90e162006-05-18 07:01:27 +0000341- Bug #1462152: file() now checks more thoroughly for invalid mode
342 strings and removes a possible "U" before passing the mode to the
343 C library function.
344
Neal Norwitz1004a532006-05-15 07:17:23 +0000345- Patch #1488312, Fix memory alignment problem on SPARC in unicode
346
Neal Norwitz373f0a72006-05-15 07:04:36 +0000347- Bug #1487966: Fix SystemError with conditional expression in assignment
348
Martin v. Löwis879768d2006-05-11 13:28:43 +0000349- WindowsError now has two error code attributes: errno, which carries
350 the error values from errno.h, and winerror, which carries the error
351 values from winerror.h. Previous versions put the winerror.h values
352 (from GetLastError()) into the errno attribute.
353
Martin v. Löwis77736712006-05-04 05:51:03 +0000354- Patch #1475845: Raise IndentationError for unexpected indent.
355
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000356- Patch #1479181: split open() and file() from being aliases for each other.
357
Tim Peters44bd9862006-06-01 13:49:23 +0000358- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
359 methods were always silently ignored by dictionaries when comparing keys.
360 They are now passed through (except when using the C API function
361 ``PyDict_GetItem()``, whose semantics did not change).
362
363- Bug #1456209: In some obscure cases it was possible for a class with a
364 custom ``__eq__()`` method to confuse dict internals when class instances
365 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
366 No, you don't have any code that did this ;-)

Trent Mick960a3f82006-06-28 20:30:41 +0000371- Bug #1295808: expat symbols should be namespaced in pyexpat
372
373- Patch #1462338: Upgrade pyexpat to expat 2.0.0
374
Brett Cannon6ee7d012006-06-08 16:23:04 +0000375- Change binascii.hexlify to accept a read-only buffer instead of only a char
376 buffer and actually follow its documentation.
377
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000378- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
379
Nick Coghlanc649ec52006-05-29 12:43:05 +0000380- Patch #1478788 (modified version): The functional extension module has
381 been renamed to _functools and a functools Python wrapper module added.
382 This provides a home for additional function related utilities that are
383 not specifically about functional programming. See PEP 309.
384
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000385- Patch #1493701: performance enhancements for struct module.
386
Georg Brandl378d5922006-05-17 14:26:50 +0000387- Patch #1490224: time.altzone is now set correctly on Cygwin.
388
Georg Brandl8d3342b2006-05-16 07:38:27 +0000389- Patch #1435422: zlib's compress and decompress objects now have a
390 copy() method.
391
Andrew MacIntyre92913322006-06-13 15:04:24 +0000392- Patch #1454481: thread stack size is now tunable at runtime for thread
393 enabled builds on Windows and systems with Posix threads support.
394
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000395- On Win32, os.listdir now supports arbitrarily-long Unicode path names
396 (up to the system limit of 32K characters).
397
398- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
399 As a result, these functions now raise WindowsError instead of OSError.
400
Tim Peters7a822da2006-05-25 21:50:17 +0000401- ``time.clock()`` on Win64 should use the high-performance Windows
402 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
403 Windows platforms).
404
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000405- Calling Tk_Init twice is refused if the first call failed as that
406 may deadlock.
407
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000408- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
409 accept it without potentially using an uninitialized pointer.
410
411- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
412 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
413 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000414
Gregory P. Smith372b5832006-06-05 18:48:21 +0000415- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000416 [pybsddb project SF patch number 1466734]
417
Gregory P. Smith372b5832006-06-05 18:48:21 +0000418- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
419 parameter is supplied. [SF pybsddb bug #1477863]
420
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000421- bsddb: the __len__ method of a DB object has been fixed to return correct
422 results. It could previously incorrectly return 0 in some cases.
423 Fixes SF bug 1493322 (pybsddb bug 1184012).
424
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000425- bsddb: the bsddb.dbtables Modify method now raises the proper error and
426 aborts the db transaction safely when a modifier callback fails.
427 Fixes SF python patch/bug #1408584.
428
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000429- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000430 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000431 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
432 database calls that would previously deadlock. [SF python bug #775414]
433
Vinay Sajip28e57612006-07-01 10:45:20 +0000434- Patch #1446489: add support for the ZIP64 extensions to zipfile.

443 functions.
444
Martin v. Löwis3798da02006-06-17 18:44:27 +0000445- Patch #812986: Update turtle output even if not tracing.
446
Vinay Sajip28e57612006-07-01 10:45:20 +0000447- Patch #1494750: Destroy master after deleting children in

449
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000450- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
451
Martin v. Löwis337487e2006-06-17 09:15:14 +0000452- Patch #763580: Add name and value arguments to Tkinter variable
453 classes.
454
Georg Brandl83cc0d02006-06-14 08:50:03 +0000455- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
456 mime.types file for determining MIME types.
457
Georg Brandl2605ca82006-06-14 06:08:31 +0000458- Bug #1339007: Shelf objects now don't raise an exception in their
459 __del__ method when initialization failed.
460
Martin v. Löwisd8251432006-06-14 05:21:04 +0000461- Patch #1455898: The MBCS codec now supports the incremental mode for
462 double-byte encodings.
463
Tim Peters43898b42006-06-14 04:09:25 +0000464- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
465 guarantee that adjacent triples in the return list always describe
466 non-adjacent blocks. Previously, a pair of matching blocks could end
467 up being described by multiple adjacent triples that formed a partition
468 of the matching pair.
469
Greg Ward0e0c9f42006-06-11 16:24:11 +0000470- Bug #1498146: fix optparse to handle Unicode strings in option help,
471 description, and epilog.
472
Greg Wardd1c797e2006-06-11 14:42:41 +0000473- Bug #1366250: minor optparse documentation error.
474
Greg Ward7f547402006-06-11 00:40:49 +0000475- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
476 clarify docs.
477
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000478- The wsgiref package has been added to the standard library.
479
Nick Coghlan676725d2006-06-08 13:54:49 +0000480- The functions update_wrapper() and wraps() have been added to the functools
481 module. These make it easier to copy relevant metadata from the original
482 function when writing wrapper functions.
483
Tim Petersd6a9eef2006-06-05 01:48:21 +0000484- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
485 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000486
Martin v. Löwis3f767792006-06-04 19:36:28 +0000487- Patch #1359618: Speed up charmap encoder by using a trie structure
488 for lookup.
489
Tim Petersd609b1a2006-06-02 23:22:51 +0000490- The functions in the ``pprint`` module now sort dictionaries by key
491 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
492 if and only if its display required more than one line, although that
493 wasn't documented. The new behavior increases predictability; e.g.,
494 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
495
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000496- Patch #1497027: try HTTP digest auth before basic auth in urllib2
497 (thanks for J. J. Lee).
498
Georg Brandl2b330372006-05-28 20:23:12 +0000499- Patch #1496206: improve urllib2 handling of passwords with respect to
500 default HTTP and HTTPS ports.
501
George Yoshidaf3c65de2006-05-28 16:39:09 +0000502- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
503
Bob Ippolito7298f272006-05-23 18:43:47 +0000504- Patch #1281707: speed up gzip.readline.
505
Georg Brandlb89316f2006-05-17 15:51:16 +0000506- Patch #1180296: Two new functions were added to the locale module:
507 format_string() to get the effect of "format % items" but locale-aware,
508 and currency() to format a monetary number with currency sign.
509
Georg Brandle3a25832006-05-17 14:56:04 +0000510- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
511 and several features added, such as speed and geometry control.
512
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000513- Patch #1488881: add support for external file objects in bz2 compressed
514 tarfiles.
515
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000516- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
517 stdout arguments, making it possible to redirect input and output
518 for remote debugging.
519
520- Patch #1484695: Update the tarfile module to version 0.8. This fixes
521 a couple of issues, notably handling of long file names using the
522 GNU LONGNAME extension.
523
524- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
525 new flag when ``name`` is already the name of an option flag.
526
527- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
528 package.
529
530- Patch #1472854: make the rlcompleter.Completer class usable on non-
531 UNIX platforms.
532
533- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
534
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000535- Bug #1472827: correctly escape newlines and tabs in attribute values in
536 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000566What's New in Python 2.5 alpha 2?
567=================================
568
569*Release date: 27-APR-2006*
570
571Core and builtins
572-----------------
573
Thomas Heller1b046642006-04-18 18:51:06 +0000574- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
575 by converting these apis from macros into exported functions again:
576
577 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
578 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
579 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
580 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
581 PyRun_String Py_CompileString
582
Martin v. Löwis45294a92006-04-18 06:24:08 +0000583- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
584
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000585- All uses of PyStructSequence_InitType have been changed to initialize
586 the type objects only once, even if the interpreter is initialized
587 multiple times.
588
Neal Norwitz61546162006-04-14 05:20:28 +0000589- Bug #1454485, array.array('u') could crash the interpreter. This was
590 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
591 to unicode when it didn't make sense. 'u#' now requires a unicode string.
592
593- Py_UNICODE is unsigned. It was always documented as unsigned, but
594 due to a bug had a signed value in previous versions.
595
Tim Peters3a5e8b12006-04-11 01:44:07 +0000596- Patch #837242: ``id()`` of any Python object always gives a positive
597 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
598 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000599 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000600 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000601
Tim Peters3a5e8b12006-04-11 01:44:07 +0000602 def __hash__(self):
603 return id(self) # WRONG
604
605 because a hash result must be a (short) Python int but it was always
606 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000607 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000608 was always usable as a hash value before this patch. That's no longer
609 necessarily so.
610
611- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000612 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000613 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000614 #1454844)
615
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000616- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
617 involving generators that have paused outside of any ``try`` or ``with``
618 blocks. (In 2.5a1, a paused generator that was part of a reference
619 cycle could not be garbage collected, regardless of whether it was
620 paused in a ``try`` or ``with`` block.)

623-----------------
624
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000625- Patch #1191065: Fix preprocessor problems on systems where recvfrom
626 is a macro.
627
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000628- Bug #1467952: os.listdir() now correctly raises an error if readdir()
629 fails with an error condition.
630
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000631- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
632
633- Bug #1117761: bsddb.*open() no longer raises an exception when using
634 the cachesize parameter.
635
636- Bug #1149413: bsddb.*open() no longer raises an exception when using
637 a temporary db (file=None) with the 'n' flag to truncate on open.
638
639- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
640 as older versions cause excessive test failures.

646-------
647
Peter Astrand7d1d4362006-07-14 14:04:45 +0000648- Bug #1223937: subprocess.CalledProcessError reports the exit status
649 of the process using the returncode attribute, instead of
650 abusing errno.
651
Tim Peters711bf302006-04-25 03:31:36 +0000652- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
653 a doctest to be skipped (the code is not run, and the expected output
654 or exception is ignored).
655
Nick Coghlanda2268f2006-04-24 04:37:15 +0000656- Fixed contextlib.nested to cope with exceptions being raised and
657 caught inside exit handlers.
658
Greg Wardab05edc2006-04-23 03:47:58 +0000659- Updated optparse module to Optik 1.5.1 (allow numeric constants in
660 hex, octal, or binary; add ``append_const`` action; keep going if
661 gettext cannot be imported; added ``OptionParser.destroy()`` method;
662 added ``epilog`` for better help generation).
663
Tim Peters21fbd572006-04-21 21:18:10 +0000664- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
665 called from a thread spawned as a side effect of importing a module.
666
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000667- The pydoc module now supports documenting packages contained in
668 .zip or .egg files.
669
670- The pkgutil module now has several new utility functions, such
671 as ``walk_packages()`` to support working with packages that are either
672 in the filesystem or zip files.
673
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000674- The mailbox module can now modify and delete messages from
675 mailboxes, in addition to simply reading them. Thanks to Gregory
676 K. Johnson for writing the code, and to the 2005 Google Summer of
677 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000678
Tim Petersc7605f22006-04-17 21:12:33 +0000679- The ``__del__`` method of class ``local`` in module ``_threading_local``
680 returned before accomplishing any of its intended cleanup.

689 Windows. Bug #1469163.
690
Phillip J. Eby47032112006-04-11 01:07:43 +0000691- The warnings, linecache, inspect, traceback, site, and doctest modules
692 were updated to work correctly with modules imported from zipfiles or
693 via other PEP 302 __loader__ objects.

701
Skip Montanaro262fb922006-04-21 02:31:07 +0000702- The pstats.Stats class accepts an optional stream keyword argument to
703 direct output to an alternate file-like object.
704

706-----
707
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000708- The Makefile now has a reindent target, which runs reindent.py on
709 the library.
710
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000711- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000714
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000715- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
716 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000717 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000718 CXX from --with-cxx-main, see description in README.
719
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000720- Patch #1429775: Link extension modules with the shared libpython.
721
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000722- Fixed a libffi build problem on MIPS systems.
723
Tim Peters8931ff12006-05-13 23:28:20 +0000724- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
725 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
726 and "%zu" for unsigned integers of type ``size_t``.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000728Tests
729-----
730
Nick Coghlanda2268f2006-04-24 04:37:15 +0000731- test_contextlib now checks contextlib.nested can cope with exceptions
732 being raised and caught inside exit handlers.
733
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000734- test_cmd_line now checks operation of the -m and -c command switches
735
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000736- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
737 it separately and by hand. It also wasn't cleaning up its changes to
738 the current Decimal context.
739
Thomas Woutersabd08882006-04-26 15:53:30 +0000740- regrtest.py now has a -M option to run tests that test the new limits of
741 containers, on 64-bit architectures. Running these tests is only sensible
742 on 64-bit machines with more than two gigabytes of memory. The argument
743 passed is the maximum amount of memory for the tests to use.

752-------------
753
Tim Petersb06d28c2006-05-12 01:57:59 +0000754- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
755
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000756- PEP 343: Added Context Types section to the library reference
757 and attempted to bring other PEP 343 related documentation into
758 line with the implementation and/or python-dev discussions.
759
Tim Peters8dc73d22006-04-24 02:03:16 +0000760- Bug #1337990: clarified that ``doctest`` does not support examples
761 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000764What's New in Python 2.5 alpha 1?
765=================================
766
Anthony Baxterebed3f62006-04-03 15:03:44 +0000767*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000768
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000769Core and builtins
770-----------------
771
Nick Coghlan43832302006-04-23 17:04:07 +0000772- PEP 338: -m command line switch now delegates to runpy.run_module
773 allowing it to support modules in packages and zipfiles
774
Martin v. Löwisc661b882006-04-20 04:54:23 +0000775- On Windows, .DLL is not an accepted file name extension for
776 extension modules anymore; extensions are only found if they
777 end in .PYD.
778
Martin v. Löwisea62d252006-04-03 10:56:49 +0000779- Bug #1421664: sys.stderr.encoding is now set to the same value as
780 sys.stdout.encoding.
781
Neal Norwitz92e212f2006-04-03 04:48:37 +0000782- __import__ accepts keyword arguments.
783
Georg Brandlccadf842006-03-31 18:54:53 +0000784- Patch #1460496: round() now accepts keyword arguments.
785
Anthony Baxter262c00a2006-03-30 10:53:17 +0000786- Fixed bug #1459029 - unicode reprs were double-escaped.
787
Hye-Shik Changd478f342006-03-23 12:32:36 +0000788- Patch #1396919: The system scope threads are reenabled on FreeBSD
789 5.4 and later versions.
790
Neal Norwitze98ccf62006-03-23 05:39:47 +0000791- Bug #1115379: Compiling a Unicode string with an encoding declaration
792 now gives a SyntaxError.
793
Georg Brandlabd1ff82006-03-18 07:59:59 +0000794- Previously, Python code had no easy way to access the contents of a
795 cell object. Now, a ``cell_contents`` attribute has been added
796 (closes patch #1170323).
797
Tim Peterscf79aac2006-03-16 01:14:46 +0000798- Patch #1123430: Python's small-object allocator now returns an arena to
799 the system ``free()`` when all memory within an arena becomes unused
800 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
801 freed. Some applications will see a drop in virtual memory size now,
802 especially long-running applications that, from time to time, temporarily
803 use a large number of small objects. Note that when Python returns an
804 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000805 platform C library will in turn return that memory to the operating system.
806 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000807 appears to be effective at least on Microsoft C and gcc-based systems.
808 Thanks to Evan Jones for hard work and patience.
809
Georg Brandl533ff6f2006-03-08 18:09:27 +0000810- Patch #1434038: property() now uses the getter's docstring if there is
811 no "doc" argument given. This makes it possible to legitimately use
812 property() as a decorator to produce a read-only property.
813
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000814- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
815 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
816 of requiring an int or long in slicing and a few other contexts, enabling
817 other objects (e.g. Numeric Python's integers) to be used as slice indices.
818
Neal Norwitz995acdf2006-03-07 05:01:00 +0000819- Fixed various bugs reported by Coverity's Prevent tool.
820
Brett Cannonbf364092006-03-01 04:25:17 +0000821- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
822 new exception base class, BaseException, which has a new message attribute.
823 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
824 Raising a string exception now raises a DeprecationWarning.
825
Thomas Woutersfb609f42006-02-28 16:37:25 +0000826- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
827 explicitly relative, using 'from .module import name' to mean 'from the same
828 package as this module is in. Imports without dots still default to the
829 old relative-then-absolute, unless 'from __future__ import
830 absolute_import' is used.
831
Brett Cannona7446e32006-02-27 23:39:10 +0000832- Properly check if 'warnings' raises an exception (usually when a filter set
833 to "error" is triggered) when raising a warning for raising string
834 exceptions.
835
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000836- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000837 The name was removed from Include/code.h.
838
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000839- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000840
Guido van Rossum1968ad32006-02-25 22:38:04 +0000841- Patch 1433928:
842 - The copy module now "copies" function objects (as atomic objects).
843 - dict.__getitem__ now looks for a __missing__ hook before raising
844 KeyError.
845
Tim Peters84ef21c2006-02-28 20:39:06 +0000846- PEP 343: with statement implemented. Needs ``from __future__ import
847 with_statement``. Use of 'with' as a variable will generate a warning.
848 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000849 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000850 The following objects have __context__ methods:
851 - The built-in file type.
852 - The thread.LockType type.
853 - The following types defined by the threading module:
854 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
855 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000856
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000857- Fix the encodings package codec search function to only search
858 inside its own package. Fixes problem reported in patch #1433198.
859
860 Note: Codec packages should implement and register their own
861 codec search function. PEP 100 has the details.
862
Tim Peters9ea89d22006-06-04 03:26:02 +0000863- PEP 353: Using ``Py_ssize_t`` as the index type.
864
865- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
866 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
867 now allow Python to make use of memory blocks exceeding 2**32 bytes for
868 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
869 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000870
Neal Norwitzfc76d632006-01-10 06:03:13 +0000871- Patch #1400181, fix unicode string formatting to not use the locale.
872 This is how string objects work. u'%f' could use , instead of .
873 for the decimal point. Now both strings and unicode always use periods.
874
Neal Norwitz671b9e32006-01-09 07:07:12 +0000875- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
876 configure would break checking curses.h.
877
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000878- Bug #959576: The pwd module is now builtin. This allows Python to be
879 built on UNIX platforms without $HOME set.
880
Neal Norwitzc10978f2005-12-19 06:07:16 +0000881- Bug #1072182, fix some potential problems if characters are signed.
882
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000883- Bug #889500, fix line number on SyntaxWarning for global declarations.
884
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000885- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
886
Neal Norwitze7214a12005-12-18 05:03:17 +0000887- Support for converting hex strings to floats no longer works.
888 This was not portable. float('0x3') now raises a ValueError.
889
Barry Warsaw2a38a862005-12-18 01:27:35 +0000890- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000891 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000892 is now displayed in interactive prompt banner.
893
Georg Brandlfa166682005-12-17 21:45:17 +0000894- Implementation of PEP 341 - Unification of try/except and try/finally.
895 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000896 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000897
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000898- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
899 now encodes backslash correctly.
900
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000901- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
902
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000903- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000904 and long longs.
905
Neal Norwitz67715f02005-11-09 06:59:35 +0000906- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000907 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000908 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000909
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000910- Replaced most Unicode charmap codecs with new ones using the
911 new Unicode translate string feature in the builtin charmap
912 codec; the codecs were created from the mapping tables available
913 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
914 encodings now include a mapping for the Apple logo)
915
Tim Peterse3547fd2005-12-16 23:13:57 +0000916- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000917
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000918- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000919
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000920- A new AST parser implementation was completed. The abstract
921 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000922 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000923
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000924- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000925 The following code now raises a SyntaxError: foo(a = i for i in range(10))
926
Neal Norwitz708e51a2005-10-03 04:48:15 +0000927- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
928
Neal Norwitz11bd1192005-10-03 00:54:56 +0000929- SF Bug #887946: fix segfault when redirecting stdin from a directory.
930 Provide a warning when a directory is passed on the command line.
931
Neal Norwitz40d37812005-10-02 01:48:49 +0000932- Fix segfault with invalid coding.
933
934- SF bug #772896: unknown encoding results in MemoryError.
935
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000936- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000937 supported a __len__() method which evaluated to False when the iterator
938 was empty.
939
Guido van Rossum630db602005-09-20 18:49:54 +0000940- On 64-bit platforms, when __len__() returns a value that cannot be
941 represented as a C int, raise OverflowError.
942
Skip Montanarof8948ca2005-09-19 03:54:46 +0000943- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000944 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000945
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000946- SF bug #893549: parsing keyword arguments was broken with a few format
947 codes.
948
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000949- Changes donated by Elemental Security to make it work on AIX 5.3
950 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
951 bug #105470: test_pwd fails on 64bit system (Opteron).
952
Guido van Rossum539c6622005-09-14 17:49:54 +0000953- Changes donated by Elemental Security to make it work on HP-UX 11 on
954 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
955
Georg Brandl4550b8d2005-08-26 06:43:52 +0000956- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000957 (fixes bug #1119418).
958
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000959- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
960
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000961- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
962 exceptions that cause a function to exit.
963
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000964- The implementation of set() and frozenset() was revised to use its
965 own internal data structure. Memory consumption is reduced by 1/3
966 and there are modest speed-ups as well. The API is unchanged.
967
Tim Petersde7990b2005-07-17 23:45:23 +0000968- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
969
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000970- SF bug #1229429: PyObject_CallMethod failed to decrement some
971 reference counts in some error exit cases.
972
Tim Petersecc6e6a2005-07-10 22:30:55 +0000973- SF bug #1185883: Python's small-object memory allocator took over
974 a block managed by the platform C library whenever a realloc specified
975 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000976 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000977 portable way to copy data from the C-managed block into Python's
978 small-object space without risking a memory fault. Python's small-object
979 realloc now leaves such blocks under the control of the platform C
980 realloc.
981
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000982- SF bug #1232517: An overflow error was not detected properly when
983 attempting to convert a large float to an int in os.utime().
984
Raymond Hettinger3296e692005-06-29 23:29:56 +0000985- SF bug #1224347: hex longs now print with lowercase letters just
986 like their int counterparts.
987
Michael W. Hudson188d4362005-06-20 16:52:57 +0000988- SF bug #1163563: the original fix for bug #1010677 ("thread Module
989 Breaks PyGILState_Ensure()") broke badly in the case of multiple
990 interpreter states; back out that fix and do a better job (see
991 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
992 for a longer write-up of the problem).
993
Michael W. Hudsondf888462005-06-03 14:41:55 +0000994- SF patch #1180995: marshal now uses a binary format by default when
995 serializing floats.
996
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000997- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
998 the routines that promise to produce IEEE 754 binary representations
999 of floats now simply copy bytes around.
1000
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001001- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1002 278.
1003
Brett Cannonc3647ac2005-04-26 03:45:26 +00001004- patch #1109424: int, long, float, complex, and unicode now check for the
1005 proper magic slot for type conversions when subclassed. Previously the
1006 magic slot was ignored during conversion. Semantics now match the way
1007 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001008 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001009 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001010 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001011
Barry Warsawc8d907c2005-04-19 23:43:40 +00001012- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1013 NULL, now raise an AttributeError when attempting to set or delete the
1014 attribute. Previously a TypeError was raised, but this was inconsistent
1015 with the equivalent pure-Python implementation.
1016
Michael W. Hudson774479c2005-04-18 08:46:17 +00001017- It is now safe to call PyGILState_Release() before
1018 PyEval_InitThreads() (note that if there is reason to believe there
1019 are multiple threads around you still must call PyEval_InitThreads()
1020 before using the Python API; this fix is for extension modules that
1021 have no way of knowing if Python is multi-threaded yet).
1022
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001023- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1024 disabled caused a crash.
1025
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001026- Bug #1165306: instancemethod_new allowed the creation of a method
1027 with im_class == im_self == NULL, which caused a crash when called.
1028
Tim Petersecc6e6a2005-07-10 22:30:55 +00001029- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001030 fixes the crash seen in bug #1165761
1031
Raymond Hettinger96229b12005-03-11 06:49:40 +00001032- Added two new builtins, any() and all().
1033
Brett Cannon409d8f22005-03-05 06:47:57 +00001034- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001035 (e.g., ``class C(): pass`` is no longer a syntax error).
1036 Patch #1176012 added support to the 'parser' module and 'compiler' package
1037 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001038
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001039- Patch #1115086: Support PY_LONGLONG in structmember.
1040
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001041- Bug #1155938: new style classes did not check that __init__() was
1042 returning None.
1043
Tim Petersecc6e6a2005-07-10 22:30:55 +00001044- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001045 ('\') with a specific error message.
1046
Martin v. Löwisff232d72005-03-03 09:24:38 +00001047- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1048
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001049- Bug #1124295: the __name__ attribute of file objects was
1050 inadvertently made inaccessible in restricted mode.
1051
Tim Petersecc6e6a2005-07-10 22:30:55 +00001052- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001053 an ferror() call.
1054
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001055- min() and max() now support key= arguments with the same meaning as in
1056 list.sort().
1057
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001058- The peephole optimizer now performs simple constant folding in expressions:
1059 (2+3) --> (5).
1060
Raymond Hettingera422c342005-01-11 03:03:27 +00001061- set and frozenset objects can now be marshalled. SF #1098985.
1062
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001063- Bug #1077106: Poor argument checking could cause memory corruption
1064 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001065
Jeremy Hyltonab630502005-02-04 18:44:06 +00001066- The parser did not complain about future statements in illegal
1067 positions. It once again reports a syntax error if a future
1068 statement occurs after anything other than a doc string.
1069
Neil Schemenauercf52c072005-08-12 17:34:58 +00001070- Change the %s format specifier for str objects so that it returns a
1071 unicode instance if the argument is not an instance of basestring and
1072 calling __str__ on the argument returns a unicode instance.
1073
Tim Petersf4e69282006-02-27 17:15:31 +00001074- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1075 current thread state when the auto-GIL-state machinery knows about
1076 it (since the thread state is being deleted, continuing to remember it
1077 can't help, but can hurt if another thread happens to get created with
1078 the same thread id).
1079
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001080Extension Modules
1081-----------------
1082

Neal Norwitz10be10c2006-03-16 06:50:13 +00001096 util, whatsound, whrandom, zmod
1097
1098- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1099
1100- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001101 is deprecated. The undocumented re.engine variable no longer exists.
1102
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001103- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1104 SS2 (single-shift 2) escape sequences correctly.
1105
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001106- The unicodedata module was updated to the 4.1 version of the Unicode
1107 database. The 3.2 version is still available as unicodedata.db_3_2_0
1108 for applications that require this specific version (such as IDNA).
1109
Neal Norwitzb62c4332006-03-04 18:35:47 +00001110- The timing module is no longer built by default. It was deprecated
1111 in PEP 4 in Python 2.0 or earlier.
1112
Guido van Rossum1968ad32006-02-25 22:38:04 +00001113- Patch 1433928: Added a new type, defaultdict, to the collections module.
1114 This uses the new __missing__ hook behavior added to dict (see above).
1115
Georg Brandldbd83392006-02-20 09:42:33 +00001116- Bug #854823: socketmodule now builds on Sun platforms even when
1117 INET_ADDRSTRLEN is not defined.
1118
Georg Brandlf4f44152006-02-18 22:29:33 +00001119- Patch #1393157: os.startfile() now has an optional argument to specify
1120 a "command verb" to invoke on the file.
1121
Neal Norwitz082b2df2006-02-07 07:04:46 +00001122- Bug #876637, prevent stack corruption when socket descriptor
1123 is larger than FD_SETSIZE.
1124
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001125- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1126 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1127 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

1130 than the system default domain.
1131
Martin v. Löwis14694662006-02-03 12:54:16 +00001132- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1133 are reported, the limit on path name lengths is removed, and stat reports
1134 WindowsError now (instead of OSError).
1135
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001136- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

Michael W. Hudson8137bea2005-07-27 20:24:40 +00001210- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
1211 the request code argument, which results in more C-like behaviour
1212 for large or negative values.
1213
Tim Petersecc6e6a2005-07-10 22:30:55 +00001214- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

1226 were set in a different thread than that which called readline.
1227

1229
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00001230- operator.itemgetter() and operator.attrgetter() now support retrieving

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001254- the cPickle module no longer accepts the deprecated None option in the
1255 args tuple returned by __reduce__().
1256
Raymond Hettingerb2594052004-12-05 09:25:51 +00001257- itertools.islice() now accepts None for the start and step arguments.
1258 This allows islice() to work more readily with slices:

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001270- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1271 been renamed to have only a single underscore prefix. This was done to
1272 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001273
Nick Coghlan43832302006-04-23 17:04:07 +00001274- PEP 338: new module runpy defines a run_module function to support
1275 executing modules which provide access to source code or a code object
1276 via the PEP 302 import mechanisms.
1277
Anthony Baxter93f5b932006-04-03 08:05:07 +00001278- The email module's parsedate_tz function now sets the daylight savings

1286 in attribute values.
1287
Anthony Baxterc51ee692006-04-01 00:57:31 +00001288- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001289 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001290 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001291 module will not be built.
1292
Tim Petersc17976e2006-04-01 00:26:53 +00001293- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1294 aren't officially supported here, and trying to use them will probably
1295 raise an exception some day. But dicts have been allowed, and "mostly
1296 worked", so support for them won't go away without warning.
1297
Georg Brandl338ef7d2006-03-31 18:42:16 +00001298- Bug #1445068: getpass.getpass() can now be given an explicit stream
1299 argument to specify where to write the prompt.
1300
Georg Brandl22ec80b2006-03-31 18:25:44 +00001301- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1308
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001309- Queue.Queue objects now support .task_done() and .join() methods
1310 to make it easier to monitor when daemon threads have completed
1311 processing all enqueued tasks. Patch #1455676.
1312
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001313- popen2.Popen objects now preserve the command in a .cmd attribute.

1316
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001317- email 4.0 package now integrated. This is largely the same as the email 3.0
1318 package that was included in Python 2.3, except that PEP 8 module names are
1319 now used (e.g. mail.message instead of email.Message). The MIME classes
1320 have been moved to a subpackage (e.g. email.mime.text instead of
1321 email.MIMEText). The old names are still supported for now. Several
1322 deprecated Message methods have been removed and lots of bugs have been
1323 fixed. More details can be found in the email package documentation.
1324
Walter Dörwald40108c92006-03-27 08:15:44 +00001325- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1326 (a subclass of tuple) that provides incremental decoders and encoders
1327 (a way to use stateful codecs without the stream API). Python functions
1328 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1329 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1330 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001331
Walter Dörwald067db482006-03-15 22:17:27 +00001332- Patch #1359365: Calling next() on a closed StringIO.String object raises
1333 a ValueError instead of a StopIteration now (like file and cString.String do).
1334 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1335 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001336
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001337- A regrtest option -w was added to re-run failed tests in verbose mode.

1343 grew an optional 'generation' argument.
1344
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00001345- A library msilib to generate Windows Installer files, and a distutils

1347
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001348- PEP 343: new module contextlib.py defines decorator @contextmanager
1349 and helpful context managers nested() and closing().
1350
Martin v. Löwis415ed932006-02-27 19:56:30 +00001351- The compiler package now supports future imports after the module docstring.
1352
Georg Brandl8f7c54e2006-02-20 08:40:38 +00001353- Bug #1413790: zipfile now sanitizes absolute archive names that are
1354 not allowed by the specs.
1355
Georg Brandlc98eeed2006-02-19 14:57:47 +00001356- Patch #1215184: FileInput now can be given an opening hook which can

Martin v. Löwis3e865952006-01-24 15:51:21 +00001385 specifications, raises IOErrors when proxies for unsupported protocols
1386 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00001409 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1410 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1411 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1412 Ronald L. Rivest offered this advice for Python:
1413
1414 "The consensus of researchers in this area (at least as
1415 expressed at the NIST Hash Function Workshop 10/31/05),
1416 is that SHA-256 is a good choice for the time being, but
1417 that research should continue, and other alternatives may
1418 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001419
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001420- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandlb9256022005-08-24 18:46:39 +00001466- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
1467 ContentTooShortException, when the actually downloaded size does not
1468 match the Content-Length header.
1469
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +00001470- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
1471
Martin v. Löwis56066d22005-08-24 07:38:12 +00001472- Bug #1178484: Return complete lines from codec stream readers
1473 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001474 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001475

Georg Brandla4a8b822005-07-15 09:13:21 +00001490- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
1491 parameter, but uses the usual "kwargs=None".
1492
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001493- textwrap now processes text chunks at O(n) speed instead of O(n**2).

1495
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00001496- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
1497 to W3C name (404 -> 'Not Found'). RFE #1216944.
1498
Georg Brandl9e43acf2005-07-04 17:16:07 +00001499- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1500 as this can cause problems with apps closing all file descriptors.
1501
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001502- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001503 it can be missing in embedded interpreters

Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001512- The tokenize module now detects and reports indentation errors.
1513 Bug #1224621.
1514
Raymond Hettinger68c04532005-06-10 11:05:19 +00001515- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001516 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001517 the generate_tokens() function now accepts a callable argument that
1518 terminates by raising StopIteration.
1519
Georg Brandl9166e1a2005-06-04 09:20:03 +00001520- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1521

1523 component of the path.
1524
Skip Montanaro174dd222005-05-14 20:54:16 +00001525- Patch #1120353: The xmlrpclib module provides better, more transparent,
1526 support for datetime.{datetime,date,time} objects. With use_datetime set
1527 to True, applications shouldn't have to fiddle with the DateTime wrapper
1528 class at all.
1529
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001530- distutils.commands.upload was added to support uploading distribution

1532
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001533- distutils.commands.register now encodes the data as UTF-8 before posting
1534 them to PyPI.
1535
Raymond Hettinger267b8682005-03-27 10:47:39 +00001536- decimal operator and comparison methods now return NotImplemented
1537 instead of raising a TypeError when interacting with other types. This
1538 allows other classes to implement __radd__ style methods and have them
1539 work as expected.
1540
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001541- Bug #1163325: Decimal infinities failed to hash. Attempting to
1542 hash a NaN raised an InvalidOperation instead of a TypeError.
1543
Tim Petersecc6e6a2005-07-10 22:30:55 +00001544- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1578
Guido van Rossumd0641422005-02-03 15:01:24 +00001579- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1580 disables recursive traversal through instance attributes, which can
1581 be exploited in various ways.
1582
Tim Peterse3547fd2005-12-16 23:13:57 +00001583- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001584 flags on the HTTP listening socket.
1585
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001586- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1587 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1588
Tim Peterse3547fd2005-12-16 23:13:57 +00001589- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001590 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1591
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001592- Bug #1110478: Revert os.environ.update to do putenv again.
1593
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001594- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1595
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001596- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1597
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001598- Enhancements to the csv module:
1599
1600 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001601 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001602 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001603 + Dialect parameter parsing has been re-implemented to improve error
1604 reporting.
1605 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1606 dictates.
1607 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001608 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001609 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001610 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1611 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001612 + reader now allows \r characters to be quoted (previously it only allowed
1613 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001614 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001615 + Dialect classes passed to the module are no longer instantiated by
1616 the module before being parsed (the former validation scheme required
1617 this, but the mechanism was unreliable).
1618 + The dialect registry now contains instances of the internal
1619 C-coded dialect type, rather than references to python objects.
1620 + the internal c-coded dialect type is now immutable.
1621 + register_dialect now accepts the same keyword dialect specifications
1622 as the reader and writer, allowing the user to register dialects
1623 without first creating a dialect class.
1624 + a configurable limit to the size of parsed fields has been added -
1625 previously, an unmatched quote character could result in the entire
1626 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001627 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001628 the parser field size limit (returning the former limit). The initial
1629 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001630 + A line_num attribute has been added to the reader object, which tracks
1631 the number of lines read from the source iterator. This is not
1632 the same as the number of records returned, as records can span
1633 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001634 + reader and writer objects were not being registered with the cyclic-GC.
1635 This has been fixed.
1636
Brett Cannone6539c42005-01-08 02:43:53 +00001637- _DummyThread objects in the threading module now delete self.__block that is
1638 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1639 lock primitives tend to be limited in number and thus should not be wasted on
1640 a _DummyThread object. Fixes bug #1089632.
1641
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001642- The imghdr module now detects Exif files.
1643
Raymond Hettinger6065d322004-12-20 23:51:53 +00001644- StringIO.truncate() now correctly adjusts the size attribute.
1645 (Bug #951915).
1646
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001647- locale.py now uses an updated locale alias table (built using
1648 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1649 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001650 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001651
Raymond Hettinger3557f422004-12-07 12:02:02 +00001652- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1653
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001654- the pickle module no longer accepts the deprecated None option in the
1655 args tuple returned by __reduce__().
1656
Brett Cannon84667c02004-12-07 03:25:18 +00001657- optparse now optionally imports gettext. This allows its use in setup.py.
1658
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001659- the pickle module no longer uses the deprecated bin parameter.
1660
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001661- the shelve module no longer uses the deprecated binary parameter.
1662
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001663- the pstats module no longer uses the deprecated ignore() method.
1664
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001665- the filecmp module no longer uses the deprecated use_statcache argument.
1666
Raymond Hettinger664347b2004-12-04 21:21:53 +00001667- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1668 extended or overridden by subclasses. Formerly, the subclassed method would
1669 be ignored by the rest of the module. (Bug #1078905).
1670
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001671- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001672 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001673
Walter Dörwald36733692004-12-22 12:50:50 +00001674- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1675 once when a size argument is given. This prevents a buffer overflow in the
1676 tokenizer with very long source lines.
1677
Barry Warsaw538561e2006-01-01 21:48:54 +00001678- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1679 immediately after creating the object, without any intervening
1680 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001681
Skip Montanaro05885812005-01-16 20:48:27 +00001682- The reconvert.quote function can now emit triple-quoted strings. The
1683 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001684
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001685- ``UserString.MutableString`` now supports negative indices in
1686 ``__setitem__`` and ``__delitem__``
1687
Greg Ward40407942005-03-05 02:53:17 +00001688- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1689 correctly.
1690
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001691- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1692 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1693 character even if the user has passed a size parameter to get a proper
1694 line ending. Remove the special handling of a "\r\n" that has been split
1695 between two lines.
1696
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001697- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1698 about illegal code points. The codec now supports PEP 293 style error
1699 handlers.
1700
Walter Dörwald78a78b02005-09-01 12:04:29 +00001701- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001702 from the input stream, so that the output is a byte string in the correct
1703 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001704
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001705- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1706 considering it exactly like a '*'.
1707
Walter Dörwald007f8df2005-10-09 19:42:27 +00001708- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1709 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001710
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001711- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1712
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001713- Patch #1413711: Certain patterns of differences were making difflib
1714 touch the recursion limit.
1715
Walter Dörwald58917a62006-03-31 15:26:22 +00001716- Bug #947906: An object oriented interface has been added to the calendar
1717 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001718 called as a script (e.g. via ``python -mcalendar``). Localized month and
1719 weekday names can be ouput (even if an exotic encoding is used) using
1720 special classes that use unicode.

1729
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001730- Build support for Win64-AMD64 was added.
1731
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001732- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1733
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001734- Patch #881820: look for openpty and forkpty also in libbsd.
1735
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001736- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1737 The zlib module is now builtin on Windows.
1738
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001739- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1740
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001741- Bug #1189330: configure did not correctly determine the necessary
1742 value of LINKCC if python was built with GCC 4.0.
1743
Trent Mick8321b422005-07-26 02:29:21 +00001744- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1745 vulnerability in zlib 1.2.1 and 1.2.2.
1746
Brett Cannon08cd5982005-04-24 22:26:38 +00001747- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1748 flags that change binary compatibility. Changes were also made to
1749 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001750 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001751
Bob Ippolitoed233462005-03-29 13:47:59 +00001752- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1753 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1754 no longer exists). This configure patch makes things right.
1755
Martin v. Löwise2713be2005-03-08 15:03:08 +00001756- Bug #1158607: Build with --disable-unicode again.
1757
Brett Cannon46d96232005-02-16 00:07:19 +00001758- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1759 defined. Discovered as a result of not being able to build on OS X.
1760
Brett Cannon516592f2004-12-07 00:42:59 +00001761- setup.py now uses the directories specified in LDFLAGS using the -L option
1762 and in CPPFLAGS using the -I option for adding library and include
1763 directories, respectively, for compiling extension modules against. This has
1764 led to the core being compiled using the values in CPPFLAGS. It also removes
1765 the need for the special-casing of both DarwinPorts and Fink for darwin since
1766 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1767 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1768 Fink, ``-I/opt/local/include`` for DarwinPorts).
1769
Brett Cannon43802422005-02-10 20:48:03 +00001770- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1771 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1772 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1773 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001775C API
1776-----
1777
Tim Petersc9d78aa2006-03-26 23:27:58 +00001778- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1779 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1780 is obtained via the ``PyObject_`` family, it must be released via the
1781 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1782 always been officially true, but when Python's small-object allocator was
1783 introduced, an attempt was made to cater to a few extension modules
1784 discovered at the time that obtained memory via ``PyObject_New`` but
1785 released it via ``PyMem_DEL``. It's years later, and if such code still
1786 exists it will fail now (probably with segfaults, but calling wrong
1787 low-level memory management functions can yield many symptoms).
1788
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001789- Added a C API for set and frozenset objects.
1790

1792
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001793- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1794 mapping argument now. This string is used as a mapping table. Byte values
1795 greater than the length of the string and 0xFFFE are treated as undefined
1796 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001803
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001804- Patch #1276356: New resource "urlfetch" is implemented. This enables
1805 even impatient people to run tests that require remote files.
