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

Neal Norwitza1f10902006-07-12 07:28:29 +000047Library
48-------
49
Tim Peters6f681472006-07-27 23:44:37 +000050- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
51 lost that tests are sorted by name before being run. This rarely
52 matters for well-written tests, but can create baffling symptoms if
53 side effects from one test to the next affect outcomes. ``DocTestFinder``
54 has been changed to sort the list of tests it returns.
55
Martin v. Löwis997ceff2006-07-27 06:38:16 +000056- The distutils version has been changed to 2.5.0.
57
Martin v. Löwis9298eff2006-07-26 12:12:56 +000058- Bug #978833: Really close underlying socket in _socketobject.close.
59
Georg Brandl0619a322006-07-26 07:40:17 +000060- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
61 with title().
62
Georg Brandlcf0c1722006-07-26 07:23:32 +000063- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
64 to recursive calls and call it with the failing package name.
65
Martin v. Löwis0b483032006-07-25 09:53:12 +000066- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
67
Georg Brandlc13c34c2006-07-24 14:09:56 +000068- Patch #1515343: Fix printing of deprecated string exceptions with a
69 value in the traceback module.
70
Greg Ward48fae7a2006-07-23 16:05:51 +000071- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
72
Martin v. Löwis426f4a12006-07-18 17:46:31 +000073- Patch #1524429: Use repr() instead of backticks in Tkinter again.
74
Brett Cannoncaebe222006-07-18 04:41:36 +000075- Bug #1520914: Change time.strftime() to accept a zero for any position in its
76 argument tuple. For arguments where zero is illegal, the value is forced to
77 the minimum value that is correct. This is to support an undocumented but
78 common way people used to fill in inconsequential information in the time
79 tuple pre-2.4.
80
Bob Ippolito5ea4bf12006-07-15 16:53:15 +000081- Patch #1220874: Update the binhex module for Mach-O.
82
Barry Warsawb110bad2006-07-21 14:51:07 +000083- The email package has improved RFC 2231 support, specifically for
84 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
85 (name*0=<blah>) parameter continuations. This may change the types of
86 values returned from email.message.Message.get_param() and friends.
87 Specifically in some cases where non-encoded continuations were used,
88 get_param() used to return a 3-tuple of (None, None, string) whereas now it
89 will just return the string (since non-encoded continuations don't have
90 charset and language parts).
91
92 Also, whereas % values were decoded in all parameter continuations, they are
93 now only decoded in encoded parameter parts.
94
Ronald Oussoren3075e162006-07-25 20:28:55 +000095- Bug #1517990: IDLE keybindings on MacOS X now work correctly
96
97- Bug #1517996: IDLE now longer shows the default Tk menu when a
98 path browser, class browser or debugger is the frontmost window on MacOS X
99
Barry Warsaw00decd72006-07-27 23:43:15 +0000100- Patch #1520294: Support for getset and member descriptors in types.py,
101 inspect.py, and pydoc.py. Specifically, this allows for querying the type
102 of an object against these built-in types and more importantly, for getting
103 their docstrings printed in the interactive interpreter's help() function.
104
Ronald Oussoren3075e162006-07-25 20:28:55 +0000105
Neal Norwitza1f10902006-07-12 07:28:29 +0000106Extension Modules
107-----------------
108
Tim Peters9cab5932006-07-28 00:30:00 +0000109- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
110 a memory leak, affecting pickles and deep copies.
111
Tim Petersbc24eee2006-07-27 01:14:53 +0000112- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000113 Paul Eggert.
114
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000115- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
116
Thomas Hellerce049a02006-07-14 17:51:14 +0000117- Patch #1521817: Index range checking on ctypes arrays containing
118 exactly one element enabled again. This allows iterating over these
119 arrays, without the need to check the array size before.
120
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000121- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000122 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000123 /dev/null in certain cases; this is now fixed.
124
Thomas Heller47d7a062006-07-12 08:43:47 +0000125- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
126 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000127
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000128- Because of a misspelled preprocessor symbol, ctypes was always
129 compiled without thread support; this is now fixed.
130
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000131- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
132 methods now allow their database parameter to be None as the
133 sleepycat API allows.
134
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000135Tests
136-----
137
138- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
139 how long the test file should take to play. Now accepts taking 2.93 secs
140 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
141
Georg Brandl6cea7d72006-07-27 15:38:33 +0000142- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``
143 and ``test_uuid`` didn't actually run any tests when run via ``regrtest.py``.
144 Now they do.

152Core and builtins
153-----------------
154
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000155- Bug #1441486: The literal representation of -(sys.maxint - 1)
156 again evaluates to a int object, not a long.
157
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000158- Bug #1501934: The scope of global variables that are locally assigned
159 using augmented assignment is now correctly determined.
160
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000161- Bug #927248: Recursive method-wrapper objects can now safely
162 be released.
163
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000164- Bug #1417699: Reject locale-specific decimal point in float()
165 and atof().
166
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000167- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
168 omit a default "error" argument for NULL pointer. This allows
169 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000170
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000171- Bug #1519018: 'as' is now validated properly in import statements.
172
Neal Norwitz28746ab2006-07-09 22:14:42 +0000173- On 64 bit systems, int literals that use less than 64 bits are
174 now ints rather than longs.
175
Neal Norwitzed657552006-07-10 00:04:44 +0000176- Bug #1512814, Fix incorrect lineno's when code at module scope
177 started after line 256.
178
Tim Peters32a83612006-07-10 21:08:24 +0000179- New function ``sys._current_frames()`` returns a dict mapping thread
180 id to topmost thread stack frame. This is for expert use, and is
181 especially useful for debugging application deadlocks. The functionality
182 was previously available in Fazal Majid's ``threadframe`` extension
183 module, but it wasn't possible to do this in a wholly threadsafe way from
184 an extension.
185
Georg Brandlad29e632006-06-21 17:45:17 +0000186Library

Martin v. Löwis8d656812006-07-10 07:23:48 +0000192 environment variable to be set in order to the SDK environment
193 for finding the compiler, include files, etc.
194
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000195- Bug #1515998: Properly generate logical ids for files in bdist_msi.
196
Nick Coghlan2d792252006-07-06 13:47:18 +0000197- warnings.py now ignores ImportWarning by default
198
Thomas Woutersadd19112006-07-05 11:03:49 +0000199- string.Template() now correctly handles tuple-values. Previously,
200 multi-value tuples would raise an exception and single-value tuples would
201 be treated as the value they contain, instead.
202
Martin v. Löwisede77f52006-07-03 13:01:35 +0000203- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
204 even if some data are received.
205
Martin v. Löwis45482392006-07-03 12:28:58 +0000206- Bug #1267547: Put proper recursive setup.py call into the

Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000214
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000215- Bug #1514703: Only setup canvas window in turtle when the canvas
216 is created.
217
Martin v. Löwis7596e832006-07-01 15:33:37 +0000218- Bug #1513223: .close() of a _socketobj now releases the underlying
219 socket again, which then gets closed as it becomes unreferenced.

228
Brett Cannon53ab5b72006-06-22 16:49:14 +0000229- Bug #1510580: The 'warnings' module improperly required that a Warning
230 category be either a types.ClassType and a subclass of Warning. The proper
231 check is just that it is a subclass with Warning as the documentation states.
232
Georg Brandlad29e632006-06-21 17:45:17 +0000233- The compiler module now correctly compiles the new try-except-finally
234 statement (bug #1509132).
235
Neal Norwitz60373cd2006-06-22 06:30:50 +0000236- The wsgiref package is now installed properly on Unix.
237
Vinay Sajip28e57612006-07-01 10:45:20 +0000238- A bug was fixed in logging.config.fileConfig() which caused a crash on
239 shutdown when fileConfig() was called multiple times.
240
Gerhard Häring762fbd32006-07-02 17:48:30 +0000241- The sqlite3 module did cut off data from the SQLite database at the first
242 null character before sending it to a custom converter. This has been fixed
243 now.
244
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000245Extension Modules
246-----------------
247
Tim Peters112aad32006-07-19 00:03:19 +0000248- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
249 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
250 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000251
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000252- Assigning None to pointer type fields in ctypes structures possible
253 overwrote the wrong fields, this is fixed now.
254
255- Fixed a segfault in _ctypes when ctypes.wintypes were imported
256 on non-Windows platforms.
257
258- Bug #1518190: The ctypes.c_void_p constructor now accepts any
259 integer or long, without range checking.
260
261- Patch #1517790: It is now possible to use custom objects in the ctypes
262 foreign function argtypes sequence as long as they provide a from_param
263 method, no longer is it required that the object is a ctypes type.
264
265- The '_ctypes' extension module now works when Python is configured
266 with the --without-threads option.
267
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000268- Bug #1513646: os.access on Windows now correctly determines write
269 access, again.
270

280-----
281
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000282- Automate Windows build process for the Win64 SSL module.
283
Tim Peters32a83612006-07-10 21:08:24 +0000284- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000285 Previously, the slight difference could cause compilation errors of the
286 'zlib' module on systems with more than one version of zlib.
287
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000288- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +0000315
Anthony Baxterd1136802006-06-19 12:04:15 +0000316*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000317
318Core and builtins
319-----------------
320
Georg Brandla56b9152006-06-19 06:35:54 +0000321- Patch #1507676: Error messages returned by invalid abstract object operations
322 (such as iterating over an integer) have been improved and now include the
323 type of the offending object to help with debugging.
324
Brett Cannonea3912b2006-06-13 21:46:41 +0000325- Bug #992017: A classic class that defined a __coerce__() method that returned
326 its arguments swapped would infinitely recurse and segfault the interpreter.
327
Neal Norwitz909eb122006-06-12 02:13:21 +0000328- Fix the socket tests so they can be run concurrently.
329
Neal Norwitzb9845e72006-06-12 02:11:18 +0000330- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000331 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000332
Brett Cannon22565aa2006-06-09 22:31:23 +0000333- Bug #532646: object.__call__() will continue looking for the __call__
334 attribute on objects until one without one is found. This leads to recursion
335 when you take a class and set its __call__ attribute to an instance of the
336 class. Originally fixed for classic classes, but this fix is for new-style.
337 Removes the infinite_rec_3 crasher.
338
Georg Brandl24250812006-06-09 18:45:48 +0000339- The string and unicode methods startswith() and endswith() now accept
340 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
341
Brett Cannonde3b0522006-06-08 17:00:45 +0000342- Buffer objects, at the C level, never used the char buffer
343 implementation even when the char buffer for the wrapped object was
344 explicitly requested (originally returned the read or write buffer).
345 Now a TypeError is raised if the char buffer is not present but is
346 requested.
347
Georg Brandlddbaa662006-06-04 21:56:52 +0000348- Patch #1346214: Statements like "if 0: suite" are now again optimized
349 away like they were in Python 2.4.
350
Georg Brandlb7c8f542006-05-27 12:30:25 +0000351- Builtin exceptions are now full-blown new-style classes instead of
352 instances pretending to be classes, which speeds up exception handling
353 by about 80% in comparison to 2.5a2.
354
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000355- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
356 Unicode 4.1.
357
Georg Brandlf4ef1162006-05-26 18:03:31 +0000358- Patch #921466: sys.path_importer_cache is now used to cache valid and
359 invalid file paths for the built-in import machinery which leads to
360 fewer open calls on startup.
361
Tim Peters696cf432006-05-24 21:10:40 +0000362- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
363 of-2 bases. The largest speedup is for inputs with about 1000 decimal
364 digits. Conversion from non-power-of-2 bases remains quadratic-time in
365 the number of input digits (it was and remains linear-time for bases
366 2, 4, 8, 16 and 32).
367
Tim Petersb713ec22006-05-23 18:45:30 +0000368- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
369 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
370 an integer close to ``sys.maxint``. This was repaired by patch
371 #1335972, which also gives a nice speedup.
372
Richard Jonescebbefc2006-05-23 18:28:17 +0000373- Patch #1337051: reduced size of frame objects.
374
375- PyErr_NewException now accepts a tuple of base classes as its
376 "base" parameter.
377
Richard Jones7c88dcc2006-05-23 10:37:38 +0000378- Patch #876206: function call speedup by retaining allocated frame
379 objects.
380
Georg Brandl7b90e162006-05-18 07:01:27 +0000381- Bug #1462152: file() now checks more thoroughly for invalid mode
382 strings and removes a possible "U" before passing the mode to the
383 C library function.
384
Neal Norwitz1004a532006-05-15 07:17:23 +0000385- Patch #1488312, Fix memory alignment problem on SPARC in unicode
386
Neal Norwitz373f0a72006-05-15 07:04:36 +0000387- Bug #1487966: Fix SystemError with conditional expression in assignment
388
Martin v. Löwis879768d2006-05-11 13:28:43 +0000389- WindowsError now has two error code attributes: errno, which carries
390 the error values from errno.h, and winerror, which carries the error
391 values from winerror.h. Previous versions put the winerror.h values
392 (from GetLastError()) into the errno attribute.
393
Martin v. Löwis77736712006-05-04 05:51:03 +0000394- Patch #1475845: Raise IndentationError for unexpected indent.
395
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000396- Patch #1479181: split open() and file() from being aliases for each other.
397
Tim Peters44bd9862006-06-01 13:49:23 +0000398- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
399 methods were always silently ignored by dictionaries when comparing keys.
400 They are now passed through (except when using the C API function
401 ``PyDict_GetItem()``, whose semantics did not change).
402
403- Bug #1456209: In some obscure cases it was possible for a class with a
404 custom ``__eq__()`` method to confuse dict internals when class instances
405 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
406 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000408Extension Modules
409-----------------
410
Trent Mick960a3f82006-06-28 20:30:41 +0000411- Bug #1295808: expat symbols should be namespaced in pyexpat
412
413- Patch #1462338: Upgrade pyexpat to expat 2.0.0
414
Brett Cannon6ee7d012006-06-08 16:23:04 +0000415- Change binascii.hexlify to accept a read-only buffer instead of only a char
416 buffer and actually follow its documentation.
417
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000418- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
419
Nick Coghlanc649ec52006-05-29 12:43:05 +0000420- Patch #1478788 (modified version): The functional extension module has
421 been renamed to _functools and a functools Python wrapper module added.
422 This provides a home for additional function related utilities that are
423 not specifically about functional programming. See PEP 309.
424
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000425- Patch #1493701: performance enhancements for struct module.
426
Georg Brandl378d5922006-05-17 14:26:50 +0000427- Patch #1490224: time.altzone is now set correctly on Cygwin.
428
Georg Brandl8d3342b2006-05-16 07:38:27 +0000429- Patch #1435422: zlib's compress and decompress objects now have a
430 copy() method.
431
Andrew MacIntyre92913322006-06-13 15:04:24 +0000432- Patch #1454481: thread stack size is now tunable at runtime for thread
433 enabled builds on Windows and systems with Posix threads support.
434
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000435- On Win32, os.listdir now supports arbitrarily-long Unicode path names
436 (up to the system limit of 32K characters).
437
438- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
439 As a result, these functions now raise WindowsError instead of OSError.
440
Tim Peters7a822da2006-05-25 21:50:17 +0000441- ``time.clock()`` on Win64 should use the high-performance Windows
442 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
443 Windows platforms).
444
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000445- Calling Tk_Init twice is refused if the first call failed as that
446 may deadlock.
447
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000448- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
449 accept it without potentially using an uninitialized pointer.
450
451- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
452 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
453 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000454
Gregory P. Smith372b5832006-06-05 18:48:21 +0000455- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000456 [pybsddb project SF patch number 1466734]
457
Gregory P. Smith372b5832006-06-05 18:48:21 +0000458- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
459 parameter is supplied. [SF pybsddb bug #1477863]
460
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000461- bsddb: the __len__ method of a DB object has been fixed to return correct
462 results. It could previously incorrectly return 0 in some cases.
463 Fixes SF bug 1493322 (pybsddb bug 1184012).
464
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000465- bsddb: the bsddb.dbtables Modify method now raises the proper error and
466 aborts the db transaction safely when a modifier callback fails.
467 Fixes SF python patch/bug #1408584.
468
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000469- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000470 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000471 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
472 database calls that would previously deadlock. [SF python bug #775414]
473
Vinay Sajip28e57612006-07-01 10:45:20 +0000474- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000475
Walter Dörwald4994d952006-06-19 08:07:50 +0000476- Patch #1506645: add Python wrappers for the curses functions
477 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000478

480-------
481
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000482- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
483 functions.
484
Martin v. Löwis3798da02006-06-17 18:44:27 +0000485- Patch #812986: Update turtle output even if not tracing.
486
Vinay Sajip28e57612006-07-01 10:45:20 +0000487- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000488 Tkinter.BaseWidget.
489
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000490- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
491
Martin v. Löwis337487e2006-06-17 09:15:14 +0000492- Patch #763580: Add name and value arguments to Tkinter variable
493 classes.
494
Georg Brandl83cc0d02006-06-14 08:50:03 +0000495- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
496 mime.types file for determining MIME types.
497
Georg Brandl2605ca82006-06-14 06:08:31 +0000498- Bug #1339007: Shelf objects now don't raise an exception in their
499 __del__ method when initialization failed.
500
Martin v. Löwisd8251432006-06-14 05:21:04 +0000501- Patch #1455898: The MBCS codec now supports the incremental mode for
502 double-byte encodings.
503
Tim Peters43898b42006-06-14 04:09:25 +0000504- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
505 guarantee that adjacent triples in the return list always describe
506 non-adjacent blocks. Previously, a pair of matching blocks could end
507 up being described by multiple adjacent triples that formed a partition
508 of the matching pair.
509
Greg Ward0e0c9f42006-06-11 16:24:11 +0000510- Bug #1498146: fix optparse to handle Unicode strings in option help,
511 description, and epilog.
512
Greg Wardd1c797e2006-06-11 14:42:41 +0000513- Bug #1366250: minor optparse documentation error.
514
Greg Ward7f547402006-06-11 00:40:49 +0000515- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
516 clarify docs.
517
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000518- The wsgiref package has been added to the standard library.
519
Nick Coghlan676725d2006-06-08 13:54:49 +0000520- The functions update_wrapper() and wraps() have been added to the functools
521 module. These make it easier to copy relevant metadata from the original
522 function when writing wrapper functions.
523
Tim Petersd6a9eef2006-06-05 01:48:21 +0000524- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
525 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000526
Martin v. Löwis3f767792006-06-04 19:36:28 +0000527- Patch #1359618: Speed up charmap encoder by using a trie structure
528 for lookup.
529
Tim Petersd609b1a2006-06-02 23:22:51 +0000530- The functions in the ``pprint`` module now sort dictionaries by key
531 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
532 if and only if its display required more than one line, although that
533 wasn't documented. The new behavior increases predictability; e.g.,
534 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
535
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000536- Patch #1497027: try HTTP digest auth before basic auth in urllib2
537 (thanks for J. J. Lee).
538
Georg Brandl2b330372006-05-28 20:23:12 +0000539- Patch #1496206: improve urllib2 handling of passwords with respect to
540 default HTTP and HTTPS ports.
541
George Yoshidaf3c65de2006-05-28 16:39:09 +0000542- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
543
Bob Ippolito7298f272006-05-23 18:43:47 +0000544- Patch #1281707: speed up gzip.readline.
545
Georg Brandlb89316f2006-05-17 15:51:16 +0000546- Patch #1180296: Two new functions were added to the locale module:
547 format_string() to get the effect of "format % items" but locale-aware,
548 and currency() to format a monetary number with currency sign.
549
Georg Brandle3a25832006-05-17 14:56:04 +0000550- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
551 and several features added, such as speed and geometry control.
552
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000553- Patch #1488881: add support for external file objects in bz2 compressed
554 tarfiles.
555
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000556- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
557 stdout arguments, making it possible to redirect input and output
558 for remote debugging.
559
560- Patch #1484695: Update the tarfile module to version 0.8. This fixes
561 a couple of issues, notably handling of long file names using the
562 GNU LONGNAME extension.
563
564- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
565 new flag when ``name`` is already the name of an option flag.
566
567- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
568 package.
569
570- Patch #1472854: make the rlcompleter.Completer class usable on non-
571 UNIX platforms.
572
573- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
574
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000575- Bug #1472827: correctly escape newlines and tabs in attribute values in
576 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000606What's New in Python 2.5 alpha 2?
607=================================
608
609*Release date: 27-APR-2006*
610
611Core and builtins
612-----------------
613
Thomas Heller1b046642006-04-18 18:51:06 +0000614- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
615 by converting these apis from macros into exported functions again:
616
617 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
618 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
619 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
620 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
621 PyRun_String Py_CompileString
622
Martin v. Löwis45294a92006-04-18 06:24:08 +0000623- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
624
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000625- All uses of PyStructSequence_InitType have been changed to initialize
626 the type objects only once, even if the interpreter is initialized
627 multiple times.

Neal Norwitz61546162006-04-14 05:20:28 +0000629- Bug #1454485, array.array('u') could crash the interpreter. This was
630 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
631 to unicode when it didn't make sense. 'u#' now requires a unicode string.
632
633- Py_UNICODE is unsigned. It was always documented as unsigned, but
634 due to a bug had a signed value in previous versions.
635
Tim Peters3a5e8b12006-04-11 01:44:07 +0000636- Patch #837242: ``id()`` of any Python object always gives a positive
637 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
638 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000639 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000640 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000641
Tim Peters3a5e8b12006-04-11 01:44:07 +0000642 def __hash__(self):
643 return id(self) # WRONG
644
645 because a hash result must be a (short) Python int but it was always
646 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000647 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000648 was always usable as a hash value before this patch. That's no longer
649 necessarily so.
650
651- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000652 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000653 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000654 #1454844)
655
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000656- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
657 involving generators that have paused outside of any ``try`` or ``with``
658 blocks. (In 2.5a1, a paused generator that was part of a reference
659 cycle could not be garbage collected, regardless of whether it was
660 paused in a ``try`` or ``with`` block.)

666 is a macro.
667
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000668- Bug #1467952: os.listdir() now correctly raises an error if readdir()
669 fails with an error condition.
670
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000671- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
672
673- Bug #1117761: bsddb.*open() no longer raises an exception when using
674 the cachesize parameter.
675
676- Bug #1149413: bsddb.*open() no longer raises an exception when using
677 a temporary db (file=None) with the 'n' flag to truncate on open.
678
679- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
680 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000681
Armin Rigoa9017c32006-04-19 11:50:27 +0000682- Patch #1062014: AF_UNIX sockets under Linux have a special
683 abstract namespace that is now fully supported.
684
Anthony Baxter51bcb682006-04-05 14:51:42 +0000685Library
686-------
687
Peter Astrand7d1d4362006-07-14 14:04:45 +0000688- Bug #1223937: subprocess.CalledProcessError reports the exit status
689 of the process using the returncode attribute, instead of
690 abusing errno.
691
Tim Peters711bf302006-04-25 03:31:36 +0000692- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
693 a doctest to be skipped (the code is not run, and the expected output
694 or exception is ignored).
695
Nick Coghlanda2268f2006-04-24 04:37:15 +0000696- Fixed contextlib.nested to cope with exceptions being raised and
697 caught inside exit handlers.
698
Greg Wardab05edc2006-04-23 03:47:58 +0000699- Updated optparse module to Optik 1.5.1 (allow numeric constants in
700 hex, octal, or binary; add ``append_const`` action; keep going if
701 gettext cannot be imported; added ``OptionParser.destroy()`` method;
702 added ``epilog`` for better help generation).
703
Tim Peters21fbd572006-04-21 21:18:10 +0000704- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
705 called from a thread spawned as a side effect of importing a module.
706
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000707- The pydoc module now supports documenting packages contained in
708 .zip or .egg files.
709
710- The pkgutil module now has several new utility functions, such
711 as ``walk_packages()`` to support working with packages that are either
712 in the filesystem or zip files.
713
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000714- The mailbox module can now modify and delete messages from
715 mailboxes, in addition to simply reading them. Thanks to Gregory
716 K. Johnson for writing the code, and to the 2005 Google Summer of
717 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000718
Tim Petersc7605f22006-04-17 21:12:33 +0000719- The ``__del__`` method of class ``local`` in module ``_threading_local``
720 returned before accomplishing any of its intended cleanup.

727
Anthony Baxtere29002c2006-04-12 12:07:31 +0000728- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
729 Windows. Bug #1469163.
730
Phillip J. Eby47032112006-04-11 01:07:43 +0000731- The warnings, linecache, inspect, traceback, site, and doctest modules
732 were updated to work correctly with modules imported from zipfiles or
733 via other PEP 302 __loader__ objects.

736 the application hasn't waited on.
737
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000738- Patch #1462222: Fix Tix.Grid.

741
Skip Montanaro262fb922006-04-21 02:31:07 +0000742- The pstats.Stats class accepts an optional stream keyword argument to
743 direct output to an alternate file-like object.
744
Anthony Baxter51bcb682006-04-05 14:51:42 +0000745Build
746-----
747
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000748- The Makefile now has a reindent target, which runs reindent.py on
749 the library.
750
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000751- Patch #1470875: Building Python with MS Free Compiler
752
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000753- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000754
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000755- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
756 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000757 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000758 CXX from --with-cxx-main, see description in README.
759
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000760- Patch #1429775: Link extension modules with the shared libpython.
761
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000762- Fixed a libffi build problem on MIPS systems.
763
Tim Peters8931ff12006-05-13 23:28:20 +0000764- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
765 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
766 and "%zu" for unsigned integers of type ``size_t``.
767
Anthony Baxter51bcb682006-04-05 14:51:42 +0000768Tests
769-----
770
Nick Coghlanda2268f2006-04-24 04:37:15 +0000771- test_contextlib now checks contextlib.nested can cope with exceptions
772 being raised and caught inside exit handlers.
773
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000774- test_cmd_line now checks operation of the -m and -c command switches
775
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000776- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
777 it separately and by hand. It also wasn't cleaning up its changes to
778 the current Decimal context.
779
Thomas Woutersabd08882006-04-26 15:53:30 +0000780- regrtest.py now has a -M option to run tests that test the new limits of
781 containers, on 64-bit architectures. Running these tests is only sensible
782 on 64-bit machines with more than two gigabytes of memory. The argument
783 passed is the maximum amount of memory for the tests to use.

792-------------
793
Tim Petersb06d28c2006-05-12 01:57:59 +0000794- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
795
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000796- PEP 343: Added Context Types section to the library reference
797 and attempted to bring other PEP 343 related documentation into
798 line with the implementation and/or python-dev discussions.
799
Tim Peters8dc73d22006-04-24 02:03:16 +0000800- Bug #1337990: clarified that ``doctest`` does not support examples
801 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000809Core and builtins
810-----------------
811
Nick Coghlan43832302006-04-23 17:04:07 +0000812- PEP 338: -m command line switch now delegates to runpy.run_module
813 allowing it to support modules in packages and zipfiles
814
Martin v. Löwisc661b882006-04-20 04:54:23 +0000815- On Windows, .DLL is not an accepted file name extension for
816 extension modules anymore; extensions are only found if they
817 end in .PYD.
818
Martin v. Löwisea62d252006-04-03 10:56:49 +0000819- Bug #1421664: sys.stderr.encoding is now set to the same value as
820 sys.stdout.encoding.
821
Neal Norwitz92e212f2006-04-03 04:48:37 +0000822- __import__ accepts keyword arguments.
823
Georg Brandlccadf842006-03-31 18:54:53 +0000824- Patch #1460496: round() now accepts keyword arguments.
825
Anthony Baxter262c00a2006-03-30 10:53:17 +0000826- Fixed bug #1459029 - unicode reprs were double-escaped.
827
Hye-Shik Changd478f342006-03-23 12:32:36 +0000828- Patch #1396919: The system scope threads are reenabled on FreeBSD
829 5.4 and later versions.
830
Neal Norwitze98ccf62006-03-23 05:39:47 +0000831- Bug #1115379: Compiling a Unicode string with an encoding declaration
832 now gives a SyntaxError.
833
Georg Brandlabd1ff82006-03-18 07:59:59 +0000834- Previously, Python code had no easy way to access the contents of a
835 cell object. Now, a ``cell_contents`` attribute has been added
836 (closes patch #1170323).
837
Tim Peterscf79aac2006-03-16 01:14:46 +0000838- Patch #1123430: Python's small-object allocator now returns an arena to
839 the system ``free()`` when all memory within an arena becomes unused
840 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
841 freed. Some applications will see a drop in virtual memory size now,
842 especially long-running applications that, from time to time, temporarily
843 use a large number of small objects. Note that when Python returns an
844 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000845 platform C library will in turn return that memory to the operating system.
846 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000847 appears to be effective at least on Microsoft C and gcc-based systems.
848 Thanks to Evan Jones for hard work and patience.
849
Georg Brandl533ff6f2006-03-08 18:09:27 +0000850- Patch #1434038: property() now uses the getter's docstring if there is
851 no "doc" argument given. This makes it possible to legitimately use
852 property() as a decorator to produce a read-only property.
853
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000854- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
855 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
856 of requiring an int or long in slicing and a few other contexts, enabling
857 other objects (e.g. Numeric Python's integers) to be used as slice indices.
858
Neal Norwitz995acdf2006-03-07 05:01:00 +0000859- Fixed various bugs reported by Coverity's Prevent tool.
860
Brett Cannonbf364092006-03-01 04:25:17 +0000861- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
862 new exception base class, BaseException, which has a new message attribute.
863 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
864 Raising a string exception now raises a DeprecationWarning.
865
Thomas Woutersfb609f42006-02-28 16:37:25 +0000866- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
867 explicitly relative, using 'from .module import name' to mean 'from the same
868 package as this module is in. Imports without dots still default to the
869 old relative-then-absolute, unless 'from __future__ import
870 absolute_import' is used.
871
Brett Cannona7446e32006-02-27 23:39:10 +0000872- Properly check if 'warnings' raises an exception (usually when a filter set
873 to "error" is triggered) when raising a warning for raising string
874 exceptions.
875
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000876- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000877 The name was removed from Include/code.h.
878
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000879- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000880
Guido van Rossum1968ad32006-02-25 22:38:04 +0000881- Patch 1433928:
882 - The copy module now "copies" function objects (as atomic objects).
883 - dict.__getitem__ now looks for a __missing__ hook before raising
884 KeyError.
885
Tim Peters84ef21c2006-02-28 20:39:06 +0000886- PEP 343: with statement implemented. Needs ``from __future__ import
887 with_statement``. Use of 'with' as a variable will generate a warning.
888 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000889 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000890 The following objects have __context__ methods:
891 - The built-in file type.
892 - The thread.LockType type.
893 - The following types defined by the threading module:
894 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
895 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000896
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000897- Fix the encodings package codec search function to only search
898 inside its own package. Fixes problem reported in patch #1433198.
899
900 Note: Codec packages should implement and register their own
901 codec search function. PEP 100 has the details.
902
Tim Peters9ea89d22006-06-04 03:26:02 +0000903- PEP 353: Using ``Py_ssize_t`` as the index type.
904
905- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
906 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
907 now allow Python to make use of memory blocks exceeding 2**32 bytes for
908 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
909 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000910
Neal Norwitzfc76d632006-01-10 06:03:13 +0000911- Patch #1400181, fix unicode string formatting to not use the locale.
912 This is how string objects work. u'%f' could use , instead of .
913 for the decimal point. Now both strings and unicode always use periods.
914
Neal Norwitz671b9e32006-01-09 07:07:12 +0000915- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
916 configure would break checking curses.h.
917
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000918- Bug #959576: The pwd module is now builtin. This allows Python to be
919 built on UNIX platforms without $HOME set.
920
Neal Norwitzc10978f2005-12-19 06:07:16 +0000921- Bug #1072182, fix some potential problems if characters are signed.
922
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000923- Bug #889500, fix line number on SyntaxWarning for global declarations.
924
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000925- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
926
Neal Norwitze7214a12005-12-18 05:03:17 +0000927- Support for converting hex strings to floats no longer works.
928 This was not portable. float('0x3') now raises a ValueError.
929
Barry Warsaw2a38a862005-12-18 01:27:35 +0000930- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000931 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000932 is now displayed in interactive prompt banner.
933
Georg Brandlfa166682005-12-17 21:45:17 +0000934- Implementation of PEP 341 - Unification of try/except and try/finally.
935 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000936 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000937
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000938- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
939 now encodes backslash correctly.
940
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000941- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
942
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000943- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000944 and long longs.
945
Neal Norwitz67715f02005-11-09 06:59:35 +0000946- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000947 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000948 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000949
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000950- Replaced most Unicode charmap codecs with new ones using the
951 new Unicode translate string feature in the builtin charmap
952 codec; the codecs were created from the mapping tables available
953 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
954 encodings now include a mapping for the Apple logo)
955
Tim Peterse3547fd2005-12-16 23:13:57 +0000956- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000957
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000958- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000959
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000960- A new AST parser implementation was completed. The abstract
961 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000962 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000963
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000964- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000965 The following code now raises a SyntaxError: foo(a = i for i in range(10))
966
Neal Norwitz708e51a2005-10-03 04:48:15 +0000967- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
968
Neal Norwitz11bd1192005-10-03 00:54:56 +0000969- SF Bug #887946: fix segfault when redirecting stdin from a directory.
970 Provide a warning when a directory is passed on the command line.
971
Neal Norwitz40d37812005-10-02 01:48:49 +0000972- Fix segfault with invalid coding.
973
974- SF bug #772896: unknown encoding results in MemoryError.
975
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000976- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000977 supported a __len__() method which evaluated to False when the iterator
978 was empty.
979
Guido van Rossum630db602005-09-20 18:49:54 +0000980- On 64-bit platforms, when __len__() returns a value that cannot be
981 represented as a C int, raise OverflowError.
982
Skip Montanarof8948ca2005-09-19 03:54:46 +0000983- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000984 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000985
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000986- SF bug #893549: parsing keyword arguments was broken with a few format
987 codes.
988
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000989- Changes donated by Elemental Security to make it work on AIX 5.3
990 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
991 bug #105470: test_pwd fails on 64bit system (Opteron).
992
Guido van Rossum539c6622005-09-14 17:49:54 +0000993- Changes donated by Elemental Security to make it work on HP-UX 11 on
994 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
995
Georg Brandl4550b8d2005-08-26 06:43:52 +0000996- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000997 (fixes bug #1119418).
998
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000999- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1000
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001001- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1002 exceptions that cause a function to exit.
1003
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001004- The implementation of set() and frozenset() was revised to use its
1005 own internal data structure. Memory consumption is reduced by 1/3
1006 and there are modest speed-ups as well. The API is unchanged.
1007
Tim Petersde7990b2005-07-17 23:45:23 +00001008- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1009
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001010- SF bug #1229429: PyObject_CallMethod failed to decrement some
1011 reference counts in some error exit cases.
1012
Tim Petersecc6e6a2005-07-10 22:30:55 +00001013- SF bug #1185883: Python's small-object memory allocator took over
1014 a block managed by the platform C library whenever a realloc specified
1015 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001016 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001017 portable way to copy data from the C-managed block into Python's
1018 small-object space without risking a memory fault. Python's small-object
1019 realloc now leaves such blocks under the control of the platform C
1020 realloc.
1021
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001022- SF bug #1232517: An overflow error was not detected properly when
1023 attempting to convert a large float to an int in os.utime().
1024
Raymond Hettinger3296e692005-06-29 23:29:56 +00001025- SF bug #1224347: hex longs now print with lowercase letters just
1026 like their int counterparts.
1027
Michael W. Hudson188d4362005-06-20 16:52:57 +00001028- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1029 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1030 interpreter states; back out that fix and do a better job (see
1031 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1032 for a longer write-up of the problem).
1033
Michael W. Hudsondf888462005-06-03 14:41:55 +00001034- SF patch #1180995: marshal now uses a binary format by default when
1035 serializing floats.
1036
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001037- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1038 the routines that promise to produce IEEE 754 binary representations
1039 of floats now simply copy bytes around.
1040
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001041- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1042 278.
1043
Brett Cannonc3647ac2005-04-26 03:45:26 +00001044- patch #1109424: int, long, float, complex, and unicode now check for the
1045 proper magic slot for type conversions when subclassed. Previously the
1046 magic slot was ignored during conversion. Semantics now match the way
1047 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001048 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001049 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001050 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001051
Barry Warsawc8d907c2005-04-19 23:43:40 +00001052- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1053 NULL, now raise an AttributeError when attempting to set or delete the
1054 attribute. Previously a TypeError was raised, but this was inconsistent
1055 with the equivalent pure-Python implementation.
1056
Michael W. Hudson774479c2005-04-18 08:46:17 +00001057- It is now safe to call PyGILState_Release() before
1058 PyEval_InitThreads() (note that if there is reason to believe there
1059 are multiple threads around you still must call PyEval_InitThreads()
1060 before using the Python API; this fix is for extension modules that
1061 have no way of knowing if Python is multi-threaded yet).
1062
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001063- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1064 disabled caused a crash.
1065
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001066- Bug #1165306: instancemethod_new allowed the creation of a method
1067 with im_class == im_self == NULL, which caused a crash when called.
1068
Tim Petersecc6e6a2005-07-10 22:30:55 +00001069- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001070 fixes the crash seen in bug #1165761
1071
Raymond Hettinger96229b12005-03-11 06:49:40 +00001072- Added two new builtins, any() and all().
1073
Brett Cannon409d8f22005-03-05 06:47:57 +00001074- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001075 (e.g., ``class C(): pass`` is no longer a syntax error).
1076 Patch #1176012 added support to the 'parser' module and 'compiler' package
1077 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001078
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001079- Patch #1115086: Support PY_LONGLONG in structmember.
1080
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001081- Bug #1155938: new style classes did not check that __init__() was
1082 returning None.
1083
Tim Petersecc6e6a2005-07-10 22:30:55 +00001084- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001085 ('\') with a specific error message.
1086
Martin v. Löwisff232d72005-03-03 09:24:38 +00001087- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1088
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001089- Bug #1124295: the __name__ attribute of file objects was
1090 inadvertently made inaccessible in restricted mode.
1091
Tim Petersecc6e6a2005-07-10 22:30:55 +00001092- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001093 an ferror() call.
1094
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001095- min() and max() now support key= arguments with the same meaning as in
1096 list.sort().
1097
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001098- The peephole optimizer now performs simple constant folding in expressions:
1099 (2+3) --> (5).
1100
Raymond Hettingera422c342005-01-11 03:03:27 +00001101- set and frozenset objects can now be marshalled. SF #1098985.
1102
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001103- Bug #1077106: Poor argument checking could cause memory corruption
1104 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001105
Jeremy Hyltonab630502005-02-04 18:44:06 +00001106- The parser did not complain about future statements in illegal
1107 positions. It once again reports a syntax error if a future
1108 statement occurs after anything other than a doc string.
1109
Neil Schemenauercf52c072005-08-12 17:34:58 +00001110- Change the %s format specifier for str objects so that it returns a
1111 unicode instance if the argument is not an instance of basestring and
1112 calling __str__ on the argument returns a unicode instance.
1113
Tim Petersf4e69282006-02-27 17:15:31 +00001114- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1115 current thread state when the auto-GIL-state machinery knows about
1116 it (since the thread state is being deleted, continuing to remember it
1117 can't help, but can hurt if another thread happens to get created with
1118 the same thread id).
1119
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001120Extension Modules
1121-----------------
1122
Georg Brandl43f08a82006-03-31 18:01:16 +00001123- Patch #1380952: fix SSL objects timing out on consecutive read()s

1126
Anthony Baxterfa869072006-03-20 05:21:58 +00001127- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1128 In addition, the existing ulaw code was updated.
1129
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001130- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001131 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001132
Neal Norwitz10be10c2006-03-16 06:50:13 +00001133- Everything under lib-old was removed. This includes the following modules:
1134 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001135 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001136 util, whatsound, whrandom, zmod
1137
1138- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1139
1140- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001141 is deprecated. The undocumented re.engine variable no longer exists.
1142
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001143- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1144 SS2 (single-shift 2) escape sequences correctly.
1145
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001146- The unicodedata module was updated to the 4.1 version of the Unicode
1147 database. The 3.2 version is still available as unicodedata.db_3_2_0
1148 for applications that require this specific version (such as IDNA).
1149
Neal Norwitzb62c4332006-03-04 18:35:47 +00001150- The timing module is no longer built by default. It was deprecated
1151 in PEP 4 in Python 2.0 or earlier.
1152
Guido van Rossum1968ad32006-02-25 22:38:04 +00001153- Patch 1433928: Added a new type, defaultdict, to the collections module.
1154 This uses the new __missing__ hook behavior added to dict (see above).
1155
Georg Brandldbd83392006-02-20 09:42:33 +00001156- Bug #854823: socketmodule now builds on Sun platforms even when
1157 INET_ADDRSTRLEN is not defined.
1158
Georg Brandlf4f44152006-02-18 22:29:33 +00001159- Patch #1393157: os.startfile() now has an optional argument to specify
1160 a "command verb" to invoke on the file.
1161
Neal Norwitz082b2df2006-02-07 07:04:46 +00001162- Bug #876637, prevent stack corruption when socket descriptor
1163 is larger than FD_SETSIZE.
1164
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001165- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1166 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1167 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1168
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001169- Patch #1422385: The nis module now supports access to domains other
1170 than the system default domain.
1171
Martin v. Löwis14694662006-02-03 12:54:16 +00001172- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1173 are reported, the limit on path name lengths is removed, and stat reports
1174 WindowsError now (instead of OSError).
1175
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001176- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
1177
Neal Norwitz62a21122006-01-25 05:21:55 +00001178- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
1179 before the env.
1180
Martin v. Löwis11017b12006-01-14 18:12:57 +00001181- Patch #1103116: Basic AF_NETLINK support.
1182
Neal Norwitz3b4fff82006-01-11 08:54:45 +00001183- Bug #1402308, (possible) segfault when using mmap.mmap(-1, ...)
1184
Neal Norwitz88bbd732006-01-10 07:05:44 +00001185- Bug #1400822, _curses over{lay,write} doesn't work when passing 6 ints.
1186 Also fix ungetmouse() which did not accept arguments properly.
1187 The code now conforms to the documented signature.
1188
Neal Norwitz5e3d8622006-01-09 06:24:35 +00001189- Bug #1400115, Fix segfault when calling curses.panel.userptr()

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001310- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1311 been renamed to have only a single underscore prefix. This was done to
1312 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001313
Nick Coghlan43832302006-04-23 17:04:07 +00001314- PEP 338: new module runpy defines a run_module function to support
1315 executing modules which provide access to source code or a code object
1316 via the PEP 302 import mechanisms.
1317
Anthony Baxter93f5b932006-04-03 08:05:07 +00001318- The email module's parsedate_tz function now sets the daylight savings
1319 flag to -1 (unknown) since it can't tell from the date whether it should

1326 in attribute values.
1327
Anthony Baxterc51ee692006-04-01 00:57:31 +00001328- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001329 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001330 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001331 module will not be built.
1332
Tim Petersc17976e2006-04-01 00:26:53 +00001333- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1334 aren't officially supported here, and trying to use them will probably
1335 raise an exception some day. But dicts have been allowed, and "mostly
1336 worked", so support for them won't go away without warning.
1337
Georg Brandl338ef7d2006-03-31 18:42:16 +00001338- Bug #1445068: getpass.getpass() can now be given an explicit stream
1339 argument to specify where to write the prompt.
1340
Georg Brandl22ec80b2006-03-31 18:25:44 +00001341- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1350 to make it easier to monitor when daemon threads have completed
1351 processing all enqueued tasks. Patch #1455676.
1352

1356
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001357- email 4.0 package now integrated. This is largely the same as the email 3.0
1358 package that was included in Python 2.3, except that PEP 8 module names are
1359 now used (e.g. mail.message instead of email.Message). The MIME classes
1360 have been moved to a subpackage (e.g. email.mime.text instead of
1361 email.MIMEText). The old names are still supported for now. Several
1362 deprecated Message methods have been removed and lots of bugs have been
1363 fixed. More details can be found in the email package documentation.
1364
Walter Dörwald40108c92006-03-27 08:15:44 +00001365- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1366 (a subclass of tuple) that provides incremental decoders and encoders
1367 (a way to use stateful codecs without the stream API). Python functions
1368 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1369 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1370 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001371
Walter Dörwald067db482006-03-15 22:17:27 +00001372- Patch #1359365: Calling next() on a closed StringIO.String object raises
1373 a ValueError instead of a StopIteration now (like file and cString.String do).
1374 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1375 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00001449 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1450 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.

1454 "The consensus of researchers in this area (at least as
1455 expressed at the NIST Hash Function Workshop 10/31/05),
1456 is that SHA-256 is a good choice for the time being, but
1457 that research should continue, and other alternatives may
1458 arise from this research. The larger SHA's also seem OK."

1513 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001514 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001515

1538
Georg Brandl9e43acf2005-07-04 17:16:07 +00001539- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1540 as this can cause problems with apps closing all file descriptors.

1553 Bug #1224621.
1554
Raymond Hettinger68c04532005-06-10 11:05:19 +00001555- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001556 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001557 the generate_tokens() function now accepts a callable argument that
1558 terminates by raising StopIteration.
1559
Georg Brandl9166e1a2005-06-04 09:20:03 +00001560- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1561

1567 to True, applications shouldn't have to fiddle with the DateTime wrapper
1568 class at all.
1569
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001570- distutils.commands.upload was added to support uploading distribution

1572
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001573- distutils.commands.register now encodes the data as UTF-8 before posting
1574 them to PyPI.
1575
Raymond Hettinger267b8682005-03-27 10:47:39 +00001576- decimal operator and comparison methods now return NotImplemented
1577 instead of raising a TypeError when interacting with other types. This
1578 allows other classes to implement __radd__ style methods and have them
1579 work as expected.
1580
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001581- Bug #1163325: Decimal infinities failed to hash. Attempting to
1582 hash a NaN raised an InvalidOperation instead of a TypeError.
1583
Tim Petersecc6e6a2005-07-10 22:30:55 +00001584- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1616
Raymond Hettingerbab41432005-02-05 01:31:19 +00001617- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1618
Guido van Rossumd0641422005-02-03 15:01:24 +00001619- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1620 disables recursive traversal through instance attributes, which can
1621 be exploited in various ways.
1622
Tim Peterse3547fd2005-12-16 23:13:57 +00001623- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001624 flags on the HTTP listening socket.
1625
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001626- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1627 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1628
Tim Peterse3547fd2005-12-16 23:13:57 +00001629- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001630 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1631
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001632- Bug #1110478: Revert os.environ.update to do putenv again.
1633
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001634- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1635
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001636- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1637
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001638- Enhancements to the csv module:
1639
1640 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001641 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001642 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001643 + Dialect parameter parsing has been re-implemented to improve error
1644 reporting.
1645 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1646 dictates.
1647 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001648 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001649 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001650 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1651 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001652 + reader now allows \r characters to be quoted (previously it only allowed
1653 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001654 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001655 + Dialect classes passed to the module are no longer instantiated by
1656 the module before being parsed (the former validation scheme required
1657 this, but the mechanism was unreliable).
1658 + The dialect registry now contains instances of the internal
1659 C-coded dialect type, rather than references to python objects.
1660 + the internal c-coded dialect type is now immutable.
1661 + register_dialect now accepts the same keyword dialect specifications
1662 as the reader and writer, allowing the user to register dialects
1663 without first creating a dialect class.
1664 + a configurable limit to the size of parsed fields has been added -
1665 previously, an unmatched quote character could result in the entire
1666 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001667 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001668 the parser field size limit (returning the former limit). The initial
1669 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001670 + A line_num attribute has been added to the reader object, which tracks
1671 the number of lines read from the source iterator. This is not
1672 the same as the number of records returned, as records can span
1673 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001674 + reader and writer objects were not being registered with the cyclic-GC.
1675 This has been fixed.
1676
Brett Cannone6539c42005-01-08 02:43:53 +00001677- _DummyThread objects in the threading module now delete self.__block that is
1678 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1679 lock primitives tend to be limited in number and thus should not be wasted on
1680 a _DummyThread object. Fixes bug #1089632.
1681
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001682- The imghdr module now detects Exif files.
1683
Raymond Hettinger6065d322004-12-20 23:51:53 +00001684- StringIO.truncate() now correctly adjusts the size attribute.
1685 (Bug #951915).
1686
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001687- locale.py now uses an updated locale alias table (built using
1688 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1689 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001690 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001691
Raymond Hettinger3557f422004-12-07 12:02:02 +00001692- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1693
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001694- the pickle module no longer accepts the deprecated None option in the
1695 args tuple returned by __reduce__().
1696
Brett Cannon84667c02004-12-07 03:25:18 +00001697- optparse now optionally imports gettext. This allows its use in setup.py.
1698
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001699- the pickle module no longer uses the deprecated bin parameter.
1700
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001701- the shelve module no longer uses the deprecated binary parameter.
1702
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001703- the pstats module no longer uses the deprecated ignore() method.
1704
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001705- the filecmp module no longer uses the deprecated use_statcache argument.
1706
Raymond Hettinger664347b2004-12-04 21:21:53 +00001707- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1708 extended or overridden by subclasses. Formerly, the subclassed method would
1709 be ignored by the rest of the module. (Bug #1078905).
1710
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001711- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001712 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001713
Walter Dörwald36733692004-12-22 12:50:50 +00001714- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1715 once when a size argument is given. This prevents a buffer overflow in the
1716 tokenizer with very long source lines.
1717
Barry Warsaw538561e2006-01-01 21:48:54 +00001718- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1719 immediately after creating the object, without any intervening
1720 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001721
Skip Montanaro05885812005-01-16 20:48:27 +00001722- The reconvert.quote function can now emit triple-quoted strings. The
1723 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001724
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001725- ``UserString.MutableString`` now supports negative indices in
1726 ``__setitem__`` and ``__delitem__``
1727
Greg Ward40407942005-03-05 02:53:17 +00001728- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1729 correctly.
1730
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001731- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1732 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1733 character even if the user has passed a size parameter to get a proper
1734 line ending. Remove the special handling of a "\r\n" that has been split
1735 between two lines.
1736
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001737- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1738 about illegal code points. The codec now supports PEP 293 style error
1739 handlers.
1740
Walter Dörwald78a78b02005-09-01 12:04:29 +00001741- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001742 from the input stream, so that the output is a byte string in the correct
1743 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001744
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001745- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1746 considering it exactly like a '*'.
1747
Walter Dörwald007f8df2005-10-09 19:42:27 +00001748- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1749 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001750
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001751- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1752
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001753- Patch #1413711: Certain patterns of differences were making difflib
1754 touch the recursion limit.
1755
Walter Dörwald58917a62006-03-31 15:26:22 +00001756- Bug #947906: An object oriented interface has been added to the calendar
1757 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001758 called as a script (e.g. via ``python -mcalendar``). Localized month and
1759 weekday names can be ouput (even if an exotic encoding is used) using
1760 special classes that use unicode.

1763-----
1764
Neal Norwitz602d3392006-03-31 08:21:40 +00001765- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1766 by using -mieee gcc option.
1767

1769
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001770- Build support for Win64-AMD64 was added.
1771
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001772- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1773
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001774- Patch #881820: look for openpty and forkpty also in libbsd.
1775
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001776- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1777 The zlib module is now builtin on Windows.
1778
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001779- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1780
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001781- Bug #1189330: configure did not correctly determine the necessary
1782 value of LINKCC if python was built with GCC 4.0.
1783
Trent Mick8321b422005-07-26 02:29:21 +00001784- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1785 vulnerability in zlib 1.2.1 and 1.2.2.
1786
Brett Cannon08cd5982005-04-24 22:26:38 +00001787- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1788 flags that change binary compatibility. Changes were also made to
1789 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001790 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001791
Bob Ippolitoed233462005-03-29 13:47:59 +00001792- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1793 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1794 no longer exists). This configure patch makes things right.
1795
Martin v. Löwise2713be2005-03-08 15:03:08 +00001796- Bug #1158607: Build with --disable-unicode again.
1797
Brett Cannon46d96232005-02-16 00:07:19 +00001798- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1799 defined. Discovered as a result of not being able to build on OS X.
1800
Brett Cannon516592f2004-12-07 00:42:59 +00001801- setup.py now uses the directories specified in LDFLAGS using the -L option
1802 and in CPPFLAGS using the -I option for adding library and include
1803 directories, respectively, for compiling extension modules against. This has
1804 led to the core being compiled using the values in CPPFLAGS. It also removes
1805 the need for the special-casing of both DarwinPorts and Fink for darwin since
1806 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1807 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1808 Fink, ``-I/opt/local/include`` for DarwinPorts).
1809
Brett Cannon43802422005-02-10 20:48:03 +00001810- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1811 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1812 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1813 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001815C API
1816-----
1817
Tim Petersc9d78aa2006-03-26 23:27:58 +00001818- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1819 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1820 is obtained via the ``PyObject_`` family, it must be released via the
1821 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1822 always been officially true, but when Python's small-object allocator was
1823 introduced, an attempt was made to cater to a few extension modules
1824 discovered at the time that obtained memory via ``PyObject_New`` but
1825 released it via ``PyMem_DEL``. It's years later, and if such code still
1826 exists it will fail now (probably with segfaults, but calling wrong
1827 low-level memory management functions can yield many symptoms).
1828
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001829- Added a C API for set and frozenset objects.
1830
Raymond Hettinger66517482004-12-03 11:45:13 +00001831- Removed PyRange_New().
1832
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001833- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1834 mapping argument now. This string is used as a mapping table. Byte values
1835 greater than the length of the string and 0xFFFE are treated as undefined
1836 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00001842- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001843
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001844- Patch #1276356: New resource "urlfetch" is implemented. This enables
1845 even impatient people to run tests that require remote files.
