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
Phillip J. Ebyf7575d02006-07-28 21:12:07 +000015- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
16 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
17 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
18 excessive filesystem operations during imports.
19
Tim Petersbc24eee2006-07-27 01:14:53 +000020- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
21 operations on signed longs that are formally undefined by C.
22 Unfortunately, at least one compiler now cares about that, so complicated
23 the code to make that compiler happy again.
24
Martin v. Löwis982e9fe2006-07-24 12:54:17 +000025- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
26
Martin v. Löwisd22968a2006-07-24 11:54:53 +000027- Patch #1232023: Stop including current directory in search
28 path on Windows.
29
Neal Norwitze1fdb322006-07-21 05:32:28 +000030- Fix some potential crashes found with failmalloc.
31
Neal Norwitze7563102006-07-17 01:00:16 +000032- Fix warnings reported by Klocwork's static analysis tool.
33
Neal Norwitz84be93b2006-07-16 01:50:38 +000034- Bug #1512814, Fix incorrect lineno's when code within a function
35 had more than 255 blank lines.
36
Georg Brandl9dceedb2006-07-12 15:31:17 +000037- Patch #1521179: Python now accepts the standard options ``--help`` and
38 ``--version`` as well as ``/?`` on Windows.
39
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +000040- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +000041 again. Fixing this problem required changing the .pyc magic number.
42 This means that .pyc files generated before 2.5c1 will be regenerated.
43
Tim Peters112aad32006-07-19 00:03:19 +000044- Bug #1524317: Compiling Python ``--without-threads`` failed.
45 The Python core compiles again then, and, in a build without threads, the
46 new ``sys._current_frames()`` returns a dictionary with one entry,
47 mapping the faux "thread id" 0 to the current frame.
48
Ronald Oussoren3075e162006-07-25 20:28:55 +000049- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +000050
Ronald Oussoren3075e162006-07-25 20:28:55 +000051

53-------
54
Tim Peters6f681472006-07-27 23:44:37 +000055- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
56 lost that tests are sorted by name before being run. This rarely
57 matters for well-written tests, but can create baffling symptoms if
58 side effects from one test to the next affect outcomes. ``DocTestFinder``
59 has been changed to sort the list of tests it returns.
60
Martin v. Löwis997ceff2006-07-27 06:38:16 +000061- The distutils version has been changed to 2.5.0.
62
Martin v. Löwis9298eff2006-07-26 12:12:56 +000063- Bug #978833: Really close underlying socket in _socketobject.close.
64
Georg Brandl0619a322006-07-26 07:40:17 +000065- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
66 with title().
67
Georg Brandlcf0c1722006-07-26 07:23:32 +000068- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
69 to recursive calls and call it with the failing package name.
70
Martin v. Löwis0b483032006-07-25 09:53:12 +000071- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
72
Georg Brandlc13c34c2006-07-24 14:09:56 +000073- Patch #1515343: Fix printing of deprecated string exceptions with a
74 value in the traceback module.
75
Greg Ward48fae7a2006-07-23 16:05:51 +000076- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
77
Martin v. Löwis426f4a12006-07-18 17:46:31 +000078- Patch #1524429: Use repr() instead of backticks in Tkinter again.
79
Brett Cannoncaebe222006-07-18 04:41:36 +000080- Bug #1520914: Change time.strftime() to accept a zero for any position in its
81 argument tuple. For arguments where zero is illegal, the value is forced to
82 the minimum value that is correct. This is to support an undocumented but
83 common way people used to fill in inconsequential information in the time
84 tuple pre-2.4.
85
Bob Ippolito5ea4bf12006-07-15 16:53:15 +000086- Patch #1220874: Update the binhex module for Mach-O.
87
Barry Warsawb110bad2006-07-21 14:51:07 +000088- The email package has improved RFC 2231 support, specifically for
89 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
90 (name*0=<blah>) parameter continuations. This may change the types of
91 values returned from email.message.Message.get_param() and friends.
92 Specifically in some cases where non-encoded continuations were used,
93 get_param() used to return a 3-tuple of (None, None, string) whereas now it
94 will just return the string (since non-encoded continuations don't have
95 charset and language parts).
96
97 Also, whereas % values were decoded in all parameter continuations, they are
98 now only decoded in encoded parameter parts.
99
Ronald Oussoren3075e162006-07-25 20:28:55 +0000100- Bug #1517990: IDLE keybindings on MacOS X now work correctly
101
102- Bug #1517996: IDLE now longer shows the default Tk menu when a
103 path browser, class browser or debugger is the frontmost window on MacOS X
104
Barry Warsaw00decd72006-07-27 23:43:15 +0000105- Patch #1520294: Support for getset and member descriptors in types.py,
106 inspect.py, and pydoc.py. Specifically, this allows for querying the type
107 of an object against these built-in types and more importantly, for getting
108 their docstrings printed in the interactive interpreter's help() function.

116=======
Tim Peters9cab5932006-07-28 00:30:00 +0000117- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
118 a memory leak, affecting pickles and deep copies.

125
Thomas Hellerce049a02006-07-14 17:51:14 +0000126- Patch #1521817: Index range checking on ctypes arrays containing
127 exactly one element enabled again. This allows iterating over these
128 arrays, without the need to check the array size before.
129
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000130- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000131 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000132 /dev/null in certain cases; this is now fixed.
133
Thomas Heller47d7a062006-07-12 08:43:47 +0000134- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
135 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000136
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000137- Because of a misspelled preprocessor symbol, ctypes was always
138 compiled without thread support; this is now fixed.
139
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000140- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
141 methods now allow their database parameter to be None as the
142 sleepycat API allows.
143
Matt Flemingec926502006-07-28 11:27:27 +0000144- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
145 bluetooth API compared with Linux and FreeBSD.
146
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000147Tests
148-----
149
150- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
151 how long the test file should take to play. Now accepts taking 2.93 secs
152 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
153
Georg Brandl4793aa32006-07-28 18:31:39 +0000154- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
155 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
156 run via ``regrtest.py``. Now they do.

164Core and builtins
165-----------------
166
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000167- Bug #1441486: The literal representation of -(sys.maxint - 1)
168 again evaluates to a int object, not a long.
169
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000170- Bug #1501934: The scope of global variables that are locally assigned
171 using augmented assignment is now correctly determined.
172
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000173- Bug #927248: Recursive method-wrapper objects can now safely
174 be released.
175
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000176- Bug #1417699: Reject locale-specific decimal point in float()
177 and atof().
178
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000179- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
180 omit a default "error" argument for NULL pointer. This allows
181 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000182
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000183- Bug #1519018: 'as' is now validated properly in import statements.
184
Neal Norwitz28746ab2006-07-09 22:14:42 +0000185- On 64 bit systems, int literals that use less than 64 bits are
186 now ints rather than longs.
187
Neal Norwitzed657552006-07-10 00:04:44 +0000188- Bug #1512814, Fix incorrect lineno's when code at module scope
189 started after line 256.
190
Tim Peters32a83612006-07-10 21:08:24 +0000191- New function ``sys._current_frames()`` returns a dict mapping thread
192 id to topmost thread stack frame. This is for expert use, and is
193 especially useful for debugging application deadlocks. The functionality
194 was previously available in Fazal Majid's ``threadframe`` extension
195 module, but it wasn't possible to do this in a wholly threadsafe way from
196 an extension.
197

199-------
200

Martin v. Löwis8d656812006-07-10 07:23:48 +0000204 environment variable to be set in order to the SDK environment
205 for finding the compiler, include files, etc.
206
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000207- Bug #1515998: Properly generate logical ids for files in bdist_msi.

210
Thomas Woutersadd19112006-07-05 11:03:49 +0000211- string.Template() now correctly handles tuple-values. Previously,
212 multi-value tuples would raise an exception and single-value tuples would
213 be treated as the value they contain, instead.
214
Martin v. Löwisede77f52006-07-03 13:01:35 +0000215- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
216 even if some data are received.
217
Martin v. Löwis45482392006-07-03 12:28:58 +0000218- Bug #1267547: Put proper recursive setup.py call into the

Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000224- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000225 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000226
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000227- Bug #1514703: Only setup canvas window in turtle when the canvas

237 sgmllib ('[' and ']' were not accepted).
238
Georg Brandl1be63af2006-06-28 20:23:25 +0000239- Fix a bug in the turtle module's end_fill function.
240
Brett Cannon53ab5b72006-06-22 16:49:14 +0000241- Bug #1510580: The 'warnings' module improperly required that a Warning
242 category be either a types.ClassType and a subclass of Warning. The proper
243 check is just that it is a subclass with Warning as the documentation states.
244
Georg Brandlad29e632006-06-21 17:45:17 +0000245- The compiler module now correctly compiles the new try-except-finally
246 statement (bug #1509132).
247
Neal Norwitz60373cd2006-06-22 06:30:50 +0000248- The wsgiref package is now installed properly on Unix.
249
Vinay Sajip28e57612006-07-01 10:45:20 +0000250- A bug was fixed in logging.config.fileConfig() which caused a crash on
251 shutdown when fileConfig() was called multiple times.
252
Gerhard Häring762fbd32006-07-02 17:48:30 +0000253- The sqlite3 module did cut off data from the SQLite database at the first

255 now.
256
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000257Extension Modules
258-----------------
259
Tim Peters112aad32006-07-19 00:03:19 +0000260- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
261 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
262 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000263
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000264- Assigning None to pointer type fields in ctypes structures possible
265 overwrote the wrong fields, this is fixed now.
266
267- Fixed a segfault in _ctypes when ctypes.wintypes were imported
268 on non-Windows platforms.
269
270- Bug #1518190: The ctypes.c_void_p constructor now accepts any
271 integer or long, without range checking.
272
273- Patch #1517790: It is now possible to use custom objects in the ctypes
274 foreign function argtypes sequence as long as they provide a from_param
275 method, no longer is it required that the object is a ctypes type.
276
277- The '_ctypes' extension module now works when Python is configured
278 with the --without-threads option.
279
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000280- Bug #1513646: os.access on Windows now correctly determines write
281 access, again.
282
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000283- Bug #1512695: cPickle.loads could crash if it was interrupted with

295
Tim Peters32a83612006-07-10 21:08:24 +0000296- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000297 Previously, the slight difference could cause compilation errors of the
298 'zlib' module on systems with more than one version of zlib.
299
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000300- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +0000329
330Core and builtins
331-----------------
332
Georg Brandla56b9152006-06-19 06:35:54 +0000333- Patch #1507676: Error messages returned by invalid abstract object operations
334 (such as iterating over an integer) have been improved and now include the
335 type of the offending object to help with debugging.
336
Brett Cannonea3912b2006-06-13 21:46:41 +0000337- Bug #992017: A classic class that defined a __coerce__() method that returned
338 its arguments swapped would infinitely recurse and segfault the interpreter.
339
Neal Norwitz909eb122006-06-12 02:13:21 +0000340- Fix the socket tests so they can be run concurrently.
341
Neal Norwitzb9845e72006-06-12 02:11:18 +0000342- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000343 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000344
Brett Cannon22565aa2006-06-09 22:31:23 +0000345- Bug #532646: object.__call__() will continue looking for the __call__
346 attribute on objects until one without one is found. This leads to recursion
347 when you take a class and set its __call__ attribute to an instance of the
348 class. Originally fixed for classic classes, but this fix is for new-style.
349 Removes the infinite_rec_3 crasher.
350
Georg Brandl24250812006-06-09 18:45:48 +0000351- The string and unicode methods startswith() and endswith() now accept
352 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
353
Brett Cannonde3b0522006-06-08 17:00:45 +0000354- Buffer objects, at the C level, never used the char buffer
355 implementation even when the char buffer for the wrapped object was
356 explicitly requested (originally returned the read or write buffer).
357 Now a TypeError is raised if the char buffer is not present but is
358 requested.
359
Georg Brandlddbaa662006-06-04 21:56:52 +0000360- Patch #1346214: Statements like "if 0: suite" are now again optimized
361 away like they were in Python 2.4.
362
Georg Brandlb7c8f542006-05-27 12:30:25 +0000363- Builtin exceptions are now full-blown new-style classes instead of
364 instances pretending to be classes, which speeds up exception handling
365 by about 80% in comparison to 2.5a2.
366
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000367- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
368 Unicode 4.1.
369
Georg Brandlf4ef1162006-05-26 18:03:31 +0000370- Patch #921466: sys.path_importer_cache is now used to cache valid and
371 invalid file paths for the built-in import machinery which leads to
372 fewer open calls on startup.
373
Tim Peters696cf432006-05-24 21:10:40 +0000374- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
375 of-2 bases. The largest speedup is for inputs with about 1000 decimal
376 digits. Conversion from non-power-of-2 bases remains quadratic-time in
377 the number of input digits (it was and remains linear-time for bases
378 2, 4, 8, 16 and 32).
379
Tim Petersb713ec22006-05-23 18:45:30 +0000380- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
381 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
382 an integer close to ``sys.maxint``. This was repaired by patch
383 #1335972, which also gives a nice speedup.
384
Richard Jonescebbefc2006-05-23 18:28:17 +0000385- Patch #1337051: reduced size of frame objects.
386
387- PyErr_NewException now accepts a tuple of base classes as its
388 "base" parameter.
389
Richard Jones7c88dcc2006-05-23 10:37:38 +0000390- Patch #876206: function call speedup by retaining allocated frame
391 objects.
392
Georg Brandl7b90e162006-05-18 07:01:27 +0000393- Bug #1462152: file() now checks more thoroughly for invalid mode
394 strings and removes a possible "U" before passing the mode to the
395 C library function.
396
Neal Norwitz1004a532006-05-15 07:17:23 +0000397- Patch #1488312, Fix memory alignment problem on SPARC in unicode
398
Neal Norwitz373f0a72006-05-15 07:04:36 +0000399- Bug #1487966: Fix SystemError with conditional expression in assignment
400
Martin v. Löwis879768d2006-05-11 13:28:43 +0000401- WindowsError now has two error code attributes: errno, which carries
402 the error values from errno.h, and winerror, which carries the error
403 values from winerror.h. Previous versions put the winerror.h values
404 (from GetLastError()) into the errno attribute.
405
Martin v. Löwis77736712006-05-04 05:51:03 +0000406- Patch #1475845: Raise IndentationError for unexpected indent.
407
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000408- Patch #1479181: split open() and file() from being aliases for each other.
409
Tim Peters44bd9862006-06-01 13:49:23 +0000410- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
411 methods were always silently ignored by dictionaries when comparing keys.
412 They are now passed through (except when using the C API function
413 ``PyDict_GetItem()``, whose semantics did not change).
414
415- Bug #1456209: In some obscure cases it was possible for a class with a
416 custom ``__eq__()`` method to confuse dict internals when class instances
417 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
418 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000420Extension Modules
421-----------------
422
Trent Mick960a3f82006-06-28 20:30:41 +0000423- Bug #1295808: expat symbols should be namespaced in pyexpat
424
425- Patch #1462338: Upgrade pyexpat to expat 2.0.0
426
Brett Cannon6ee7d012006-06-08 16:23:04 +0000427- Change binascii.hexlify to accept a read-only buffer instead of only a char
428 buffer and actually follow its documentation.
429
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000430- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
431
Nick Coghlanc649ec52006-05-29 12:43:05 +0000432- Patch #1478788 (modified version): The functional extension module has
433 been renamed to _functools and a functools Python wrapper module added.
434 This provides a home for additional function related utilities that are
435 not specifically about functional programming. See PEP 309.
436
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000437- Patch #1493701: performance enhancements for struct module.
438
Georg Brandl378d5922006-05-17 14:26:50 +0000439- Patch #1490224: time.altzone is now set correctly on Cygwin.
440
Georg Brandl8d3342b2006-05-16 07:38:27 +0000441- Patch #1435422: zlib's compress and decompress objects now have a
442 copy() method.
443
Andrew MacIntyre92913322006-06-13 15:04:24 +0000444- Patch #1454481: thread stack size is now tunable at runtime for thread
445 enabled builds on Windows and systems with Posix threads support.
446
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000447- On Win32, os.listdir now supports arbitrarily-long Unicode path names
448 (up to the system limit of 32K characters).
449
450- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
451 As a result, these functions now raise WindowsError instead of OSError.
452
Tim Peters7a822da2006-05-25 21:50:17 +0000453- ``time.clock()`` on Win64 should use the high-performance Windows
454 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
455 Windows platforms).
456
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000457- Calling Tk_Init twice is refused if the first call failed as that
458 may deadlock.
459
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000460- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
461 accept it without potentially using an uninitialized pointer.
462
463- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
464 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
465 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000466
Gregory P. Smith372b5832006-06-05 18:48:21 +0000467- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000468 [pybsddb project SF patch number 1466734]
469
Gregory P. Smith372b5832006-06-05 18:48:21 +0000470- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
471 parameter is supplied. [SF pybsddb bug #1477863]
472
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000473- bsddb: the __len__ method of a DB object has been fixed to return correct
474 results. It could previously incorrectly return 0 in some cases.
475 Fixes SF bug 1493322 (pybsddb bug 1184012).
476
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000477- bsddb: the bsddb.dbtables Modify method now raises the proper error and
478 aborts the db transaction safely when a modifier callback fails.
479 Fixes SF python patch/bug #1408584.
480
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000481- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000482 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000483 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
484 database calls that would previously deadlock. [SF python bug #775414]
485
Vinay Sajip28e57612006-07-01 10:45:20 +0000486- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000487
Walter Dörwald4994d952006-06-19 08:07:50 +0000488- Patch #1506645: add Python wrappers for the curses functions
489 is_term_resized, resize_term and resizeterm.

493
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000494- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
495 functions.
496
Martin v. Löwis3798da02006-06-17 18:44:27 +0000497- Patch #812986: Update turtle output even if not tracing.
498
Vinay Sajip28e57612006-07-01 10:45:20 +0000499- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000500 Tkinter.BaseWidget.
501
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000502- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
503
Martin v. Löwis337487e2006-06-17 09:15:14 +0000504- Patch #763580: Add name and value arguments to Tkinter variable
505 classes.
506
Georg Brandl83cc0d02006-06-14 08:50:03 +0000507- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
508 mime.types file for determining MIME types.
509
Georg Brandl2605ca82006-06-14 06:08:31 +0000510- Bug #1339007: Shelf objects now don't raise an exception in their
511 __del__ method when initialization failed.
512
Martin v. Löwisd8251432006-06-14 05:21:04 +0000513- Patch #1455898: The MBCS codec now supports the incremental mode for
514 double-byte encodings.
515
Tim Peters43898b42006-06-14 04:09:25 +0000516- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
517 guarantee that adjacent triples in the return list always describe
518 non-adjacent blocks. Previously, a pair of matching blocks could end
519 up being described by multiple adjacent triples that formed a partition
520 of the matching pair.
521
Greg Ward0e0c9f42006-06-11 16:24:11 +0000522- Bug #1498146: fix optparse to handle Unicode strings in option help,
523 description, and epilog.
524
Greg Wardd1c797e2006-06-11 14:42:41 +0000525- Bug #1366250: minor optparse documentation error.
526
Greg Ward7f547402006-06-11 00:40:49 +0000527- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
528 clarify docs.
529
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000530- The wsgiref package has been added to the standard library.
531
Nick Coghlan676725d2006-06-08 13:54:49 +0000532- The functions update_wrapper() and wraps() have been added to the functools
533 module. These make it easier to copy relevant metadata from the original
534 function when writing wrapper functions.
535
Tim Petersd6a9eef2006-06-05 01:48:21 +0000536- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
537 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000538
Martin v. Löwis3f767792006-06-04 19:36:28 +0000539- Patch #1359618: Speed up charmap encoder by using a trie structure
540 for lookup.
541
Tim Petersd609b1a2006-06-02 23:22:51 +0000542- The functions in the ``pprint`` module now sort dictionaries by key
543 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
544 if and only if its display required more than one line, although that
545 wasn't documented. The new behavior increases predictability; e.g.,
546 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
547
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000548- Patch #1497027: try HTTP digest auth before basic auth in urllib2
549 (thanks for J. J. Lee).
550
Georg Brandl2b330372006-05-28 20:23:12 +0000551- Patch #1496206: improve urllib2 handling of passwords with respect to
552 default HTTP and HTTPS ports.
553
George Yoshidaf3c65de2006-05-28 16:39:09 +0000554- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
555
Bob Ippolito7298f272006-05-23 18:43:47 +0000556- Patch #1281707: speed up gzip.readline.
557
Georg Brandlb89316f2006-05-17 15:51:16 +0000558- Patch #1180296: Two new functions were added to the locale module:
559 format_string() to get the effect of "format % items" but locale-aware,
560 and currency() to format a monetary number with currency sign.
561
Georg Brandle3a25832006-05-17 14:56:04 +0000562- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
563 and several features added, such as speed and geometry control.
564
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000565- Patch #1488881: add support for external file objects in bz2 compressed
566 tarfiles.
567
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000568- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
569 stdout arguments, making it possible to redirect input and output
570 for remote debugging.
571
572- Patch #1484695: Update the tarfile module to version 0.8. This fixes
573 a couple of issues, notably handling of long file names using the
574 GNU LONGNAME extension.
575
576- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
577 new flag when ``name`` is already the name of an option flag.
578
579- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
580 package.
581
582- Patch #1472854: make the rlcompleter.Completer class usable on non-
583 UNIX platforms.
584
585- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
586
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000587- Bug #1472827: correctly escape newlines and tabs in attribute values in

625
Thomas Heller1b046642006-04-18 18:51:06 +0000626- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
627 by converting these apis from macros into exported functions again:
628
629 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
630 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
631 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
632 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
633 PyRun_String Py_CompileString
634
Martin v. Löwis45294a92006-04-18 06:24:08 +0000635- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
636
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000637- All uses of PyStructSequence_InitType have been changed to initialize
638 the type objects only once, even if the interpreter is initialized
639 multiple times.
640
Neal Norwitz61546162006-04-14 05:20:28 +0000641- Bug #1454485, array.array('u') could crash the interpreter. This was
642 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
643 to unicode when it didn't make sense. 'u#' now requires a unicode string.
644
645- Py_UNICODE is unsigned. It was always documented as unsigned, but
646 due to a bug had a signed value in previous versions.
647
Tim Peters3a5e8b12006-04-11 01:44:07 +0000648- Patch #837242: ``id()`` of any Python object always gives a positive
649 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
650 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000651 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000652 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000653
Tim Peters3a5e8b12006-04-11 01:44:07 +0000654 def __hash__(self):
655 return id(self) # WRONG
656
657 because a hash result must be a (short) Python int but it was always
658 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000659 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000660 was always usable as a hash value before this patch. That's no longer
661 necessarily so.
662
663- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000664 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000665 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000666 #1454844)
667
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000668- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
669 involving generators that have paused outside of any ``try`` or ``with``
670 blocks. (In 2.5a1, a paused generator that was part of a reference
671 cycle could not be garbage collected, regardless of whether it was
672 paused in a ``try`` or ``with`` block.)

676
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000677- Patch #1191065: Fix preprocessor problems on systems where recvfrom
678 is a macro.
679
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000680- Bug #1467952: os.listdir() now correctly raises an error if readdir()
681 fails with an error condition.
682
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000683- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
684
685- Bug #1117761: bsddb.*open() no longer raises an exception when using
686 the cachesize parameter.
687
688- Bug #1149413: bsddb.*open() no longer raises an exception when using
689 a temporary db (file=None) with the 'n' flag to truncate on open.
690
691- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
692 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000693
Armin Rigoa9017c32006-04-19 11:50:27 +0000694- Patch #1062014: AF_UNIX sockets under Linux have a special
695 abstract namespace that is now fully supported.
696
Anthony Baxter51bcb682006-04-05 14:51:42 +0000697Library
698-------
699
Peter Astrand7d1d4362006-07-14 14:04:45 +0000700- Bug #1223937: subprocess.CalledProcessError reports the exit status
701 of the process using the returncode attribute, instead of
702 abusing errno.
703
Tim Peters711bf302006-04-25 03:31:36 +0000704- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
705 a doctest to be skipped (the code is not run, and the expected output
706 or exception is ignored).
707
Nick Coghlanda2268f2006-04-24 04:37:15 +0000708- Fixed contextlib.nested to cope with exceptions being raised and
709 caught inside exit handlers.
710
Greg Wardab05edc2006-04-23 03:47:58 +0000711- Updated optparse module to Optik 1.5.1 (allow numeric constants in
712 hex, octal, or binary; add ``append_const`` action; keep going if
713 gettext cannot be imported; added ``OptionParser.destroy()`` method;
714 added ``epilog`` for better help generation).
715
Tim Peters21fbd572006-04-21 21:18:10 +0000716- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
717 called from a thread spawned as a side effect of importing a module.
718
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000719- The pydoc module now supports documenting packages contained in
720 .zip or .egg files.
721
722- The pkgutil module now has several new utility functions, such
723 as ``walk_packages()`` to support working with packages that are either
724 in the filesystem or zip files.
725
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000726- The mailbox module can now modify and delete messages from
727 mailboxes, in addition to simply reading them. Thanks to Gregory
728 K. Johnson for writing the code, and to the 2005 Google Summer of
729 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000730
Tim Petersc7605f22006-04-17 21:12:33 +0000731- The ``__del__`` method of class ``local`` in module ``_threading_local``
732 returned before accomplishing any of its intended cleanup.
733
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000734- Patch #790710: Add breakpoint command lists in pdb.
735
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000736- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000738- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
739
Anthony Baxtere29002c2006-04-12 12:07:31 +0000740- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
741 Windows. Bug #1469163.
742
Phillip J. Eby47032112006-04-11 01:07:43 +0000743- The warnings, linecache, inspect, traceback, site, and doctest modules
744 were updated to work correctly with modules imported from zipfiles or
745 via other PEP 302 __loader__ objects.
746
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000747- Patch #1467770: Reduce usage of subprocess._active to processes which
748 the application hasn't waited on.
749
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000750- Patch #1462222: Fix Tix.Grid.
751
Neal Norwitza31bf182006-04-09 03:35:43 +0000752- Fix exception when doing glob.glob('anything*/')
753
Skip Montanaro262fb922006-04-21 02:31:07 +0000754- The pstats.Stats class accepts an optional stream keyword argument to
755 direct output to an alternate file-like object.
756
Anthony Baxter51bcb682006-04-05 14:51:42 +0000757Build
758-----
759
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000760- The Makefile now has a reindent target, which runs reindent.py on
761 the library.
762
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000763- Patch #1470875: Building Python with MS Free Compiler
764
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000765- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000766
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000767- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
768 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000769 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000770 CXX from --with-cxx-main, see description in README.
771
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000772- Patch #1429775: Link extension modules with the shared libpython.
773
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000774- Fixed a libffi build problem on MIPS systems.
775
Tim Peters8931ff12006-05-13 23:28:20 +0000776- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
777 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
778 and "%zu" for unsigned integers of type ``size_t``.
779
Anthony Baxter51bcb682006-04-05 14:51:42 +0000780Tests
781-----
782
Nick Coghlanda2268f2006-04-24 04:37:15 +0000783- test_contextlib now checks contextlib.nested can cope with exceptions
784 being raised and caught inside exit handlers.
785
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000786- test_cmd_line now checks operation of the -m and -c command switches
787
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000788- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
789 it separately and by hand. It also wasn't cleaning up its changes to
790 the current Decimal context.
791
Thomas Woutersabd08882006-04-26 15:53:30 +0000792- regrtest.py now has a -M option to run tests that test the new limits of
793 containers, on 64-bit architectures. Running these tests is only sensible
794 on 64-bit machines with more than two gigabytes of memory. The argument
795 passed is the maximum amount of memory for the tests to use.

804-------------
805
Tim Petersb06d28c2006-05-12 01:57:59 +0000806- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
807
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000808- PEP 343: Added Context Types section to the library reference
809 and attempted to bring other PEP 343 related documentation into
810 line with the implementation and/or python-dev discussions.
811
Tim Peters8dc73d22006-04-24 02:03:16 +0000812- Bug #1337990: clarified that ``doctest`` does not support examples
813 requiring both expected output and an exception.

Anthony Baxterebed3f62006-04-03 15:03:44 +0000819*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000820
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000821Core and builtins
822-----------------
823
Nick Coghlan43832302006-04-23 17:04:07 +0000824- PEP 338: -m command line switch now delegates to runpy.run_module
825 allowing it to support modules in packages and zipfiles
826
Martin v. Löwisc661b882006-04-20 04:54:23 +0000827- On Windows, .DLL is not an accepted file name extension for
828 extension modules anymore; extensions are only found if they
829 end in .PYD.
830
Martin v. Löwisea62d252006-04-03 10:56:49 +0000831- Bug #1421664: sys.stderr.encoding is now set to the same value as
832 sys.stdout.encoding.
833
Neal Norwitz92e212f2006-04-03 04:48:37 +0000834- __import__ accepts keyword arguments.
835
Georg Brandlccadf842006-03-31 18:54:53 +0000836- Patch #1460496: round() now accepts keyword arguments.
837
Anthony Baxter262c00a2006-03-30 10:53:17 +0000838- Fixed bug #1459029 - unicode reprs were double-escaped.
839
Hye-Shik Changd478f342006-03-23 12:32:36 +0000840- Patch #1396919: The system scope threads are reenabled on FreeBSD
841 5.4 and later versions.
842
Neal Norwitze98ccf62006-03-23 05:39:47 +0000843- Bug #1115379: Compiling a Unicode string with an encoding declaration
844 now gives a SyntaxError.
845
Georg Brandlabd1ff82006-03-18 07:59:59 +0000846- Previously, Python code had no easy way to access the contents of a
847 cell object. Now, a ``cell_contents`` attribute has been added
848 (closes patch #1170323).
849
Tim Peterscf79aac2006-03-16 01:14:46 +0000850- Patch #1123430: Python's small-object allocator now returns an arena to
851 the system ``free()`` when all memory within an arena becomes unused
852 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
853 freed. Some applications will see a drop in virtual memory size now,
854 especially long-running applications that, from time to time, temporarily
855 use a large number of small objects. Note that when Python returns an
856 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000857 platform C library will in turn return that memory to the operating system.
858 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000859 appears to be effective at least on Microsoft C and gcc-based systems.
860 Thanks to Evan Jones for hard work and patience.
861
Georg Brandl533ff6f2006-03-08 18:09:27 +0000862- Patch #1434038: property() now uses the getter's docstring if there is
863 no "doc" argument given. This makes it possible to legitimately use
864 property() as a decorator to produce a read-only property.
865
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000866- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
867 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
868 of requiring an int or long in slicing and a few other contexts, enabling
869 other objects (e.g. Numeric Python's integers) to be used as slice indices.
870
Neal Norwitz995acdf2006-03-07 05:01:00 +0000871- Fixed various bugs reported by Coverity's Prevent tool.
872
Brett Cannonbf364092006-03-01 04:25:17 +0000873- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
874 new exception base class, BaseException, which has a new message attribute.
875 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
876 Raising a string exception now raises a DeprecationWarning.
877
Thomas Woutersfb609f42006-02-28 16:37:25 +0000878- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
879 explicitly relative, using 'from .module import name' to mean 'from the same
880 package as this module is in. Imports without dots still default to the
881 old relative-then-absolute, unless 'from __future__ import
882 absolute_import' is used.
883
Brett Cannona7446e32006-02-27 23:39:10 +0000884- Properly check if 'warnings' raises an exception (usually when a filter set
885 to "error" is triggered) when raising a warning for raising string
886 exceptions.
887
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000888- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000889 The name was removed from Include/code.h.
890
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000891- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000892
Guido van Rossum1968ad32006-02-25 22:38:04 +0000893- Patch 1433928:
894 - The copy module now "copies" function objects (as atomic objects).
895 - dict.__getitem__ now looks for a __missing__ hook before raising
896 KeyError.
897
Tim Peters84ef21c2006-02-28 20:39:06 +0000898- PEP 343: with statement implemented. Needs ``from __future__ import
899 with_statement``. Use of 'with' as a variable will generate a warning.
900 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000901 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000902 The following objects have __context__ methods:
903 - The built-in file type.
904 - The thread.LockType type.
905 - The following types defined by the threading module:
906 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
907 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000908
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000909- Fix the encodings package codec search function to only search
910 inside its own package. Fixes problem reported in patch #1433198.
911
912 Note: Codec packages should implement and register their own
913 codec search function. PEP 100 has the details.
914
Tim Peters9ea89d22006-06-04 03:26:02 +0000915- PEP 353: Using ``Py_ssize_t`` as the index type.
916
917- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
918 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
919 now allow Python to make use of memory blocks exceeding 2**32 bytes for
920 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
921 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000922
Neal Norwitzfc76d632006-01-10 06:03:13 +0000923- Patch #1400181, fix unicode string formatting to not use the locale.
924 This is how string objects work. u'%f' could use , instead of .
925 for the decimal point. Now both strings and unicode always use periods.
926
Neal Norwitz671b9e32006-01-09 07:07:12 +0000927- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
928 configure would break checking curses.h.

Georg Brandlcd4d1e82005-12-27 17:37:07 +0000930- Bug #959576: The pwd module is now builtin. This allows Python to be
931 built on UNIX platforms without $HOME set.
932
Neal Norwitzc10978f2005-12-19 06:07:16 +0000933- Bug #1072182, fix some potential problems if characters are signed.
934
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000935- Bug #889500, fix line number on SyntaxWarning for global declarations.
936
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000937- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
938
Neal Norwitze7214a12005-12-18 05:03:17 +0000939- Support for converting hex strings to floats no longer works.
940 This was not portable. float('0x3') now raises a ValueError.
941
Barry Warsaw2a38a862005-12-18 01:27:35 +0000942- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000943 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000944 is now displayed in interactive prompt banner.
945
Georg Brandlfa166682005-12-17 21:45:17 +0000946- Implementation of PEP 341 - Unification of try/except and try/finally.
947 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000948 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000949
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000950- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
951 now encodes backslash correctly.
952
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000953- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
954
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000955- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000956 and long longs.
957
Neal Norwitz67715f02005-11-09 06:59:35 +0000958- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000959 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000960 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000961
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000962- Replaced most Unicode charmap codecs with new ones using the
963 new Unicode translate string feature in the builtin charmap
964 codec; the codecs were created from the mapping tables available
965 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
966 encodings now include a mapping for the Apple logo)
967
Tim Peterse3547fd2005-12-16 23:13:57 +0000968- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000969
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000970- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000971
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000972- A new AST parser implementation was completed. The abstract
973 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000974 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000975
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000976- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000977 The following code now raises a SyntaxError: foo(a = i for i in range(10))
978
Neal Norwitz708e51a2005-10-03 04:48:15 +0000979- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
980
Neal Norwitz11bd1192005-10-03 00:54:56 +0000981- SF Bug #887946: fix segfault when redirecting stdin from a directory.
982 Provide a warning when a directory is passed on the command line.
983
Neal Norwitz40d37812005-10-02 01:48:49 +0000984- Fix segfault with invalid coding.
985
986- SF bug #772896: unknown encoding results in MemoryError.
987
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000988- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000989 supported a __len__() method which evaluated to False when the iterator
990 was empty.
991
Guido van Rossum630db602005-09-20 18:49:54 +0000992- On 64-bit platforms, when __len__() returns a value that cannot be
993 represented as a C int, raise OverflowError.
994
Skip Montanarof8948ca2005-09-19 03:54:46 +0000995- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000996 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000997
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000998- SF bug #893549: parsing keyword arguments was broken with a few format
999 codes.
1000
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001001- Changes donated by Elemental Security to make it work on AIX 5.3
1002 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1003 bug #105470: test_pwd fails on 64bit system (Opteron).
1004
Guido van Rossum539c6622005-09-14 17:49:54 +00001005- Changes donated by Elemental Security to make it work on HP-UX 11 on
1006 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1007
Georg Brandl4550b8d2005-08-26 06:43:52 +00001008- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001009 (fixes bug #1119418).
1010
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001011- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1012
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001013- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1014 exceptions that cause a function to exit.
1015
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001016- The implementation of set() and frozenset() was revised to use its
1017 own internal data structure. Memory consumption is reduced by 1/3
1018 and there are modest speed-ups as well. The API is unchanged.
1019
Tim Petersde7990b2005-07-17 23:45:23 +00001020- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1021
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001022- SF bug #1229429: PyObject_CallMethod failed to decrement some
1023 reference counts in some error exit cases.
1024
Tim Petersecc6e6a2005-07-10 22:30:55 +00001025- SF bug #1185883: Python's small-object memory allocator took over
1026 a block managed by the platform C library whenever a realloc specified
1027 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001028 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001029 portable way to copy data from the C-managed block into Python's
1030 small-object space without risking a memory fault. Python's small-object
1031 realloc now leaves such blocks under the control of the platform C
1032 realloc.
1033
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001034- SF bug #1232517: An overflow error was not detected properly when
1035 attempting to convert a large float to an int in os.utime().
1036
Raymond Hettinger3296e692005-06-29 23:29:56 +00001037- SF bug #1224347: hex longs now print with lowercase letters just
1038 like their int counterparts.
1039
Michael W. Hudson188d4362005-06-20 16:52:57 +00001040- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1041 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1042 interpreter states; back out that fix and do a better job (see
1043 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1044 for a longer write-up of the problem).
1045
Michael W. Hudsondf888462005-06-03 14:41:55 +00001046- SF patch #1180995: marshal now uses a binary format by default when
1047 serializing floats.
1048
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001049- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1050 the routines that promise to produce IEEE 754 binary representations
1051 of floats now simply copy bytes around.
1052
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001053- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1054 278.
1055
Brett Cannonc3647ac2005-04-26 03:45:26 +00001056- patch #1109424: int, long, float, complex, and unicode now check for the
1057 proper magic slot for type conversions when subclassed. Previously the
1058 magic slot was ignored during conversion. Semantics now match the way
1059 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001060 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001061 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001062 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001063
Barry Warsawc8d907c2005-04-19 23:43:40 +00001064- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1065 NULL, now raise an AttributeError when attempting to set or delete the
1066 attribute. Previously a TypeError was raised, but this was inconsistent
1067 with the equivalent pure-Python implementation.
1068
Michael W. Hudson774479c2005-04-18 08:46:17 +00001069- It is now safe to call PyGILState_Release() before
1070 PyEval_InitThreads() (note that if there is reason to believe there
1071 are multiple threads around you still must call PyEval_InitThreads()
1072 before using the Python API; this fix is for extension modules that
1073 have no way of knowing if Python is multi-threaded yet).
1074
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001075- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1076 disabled caused a crash.
1077
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001078- Bug #1165306: instancemethod_new allowed the creation of a method
1079 with im_class == im_self == NULL, which caused a crash when called.
1080
Tim Petersecc6e6a2005-07-10 22:30:55 +00001081- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001082 fixes the crash seen in bug #1165761
1083
Raymond Hettinger96229b12005-03-11 06:49:40 +00001084- Added two new builtins, any() and all().
1085
Brett Cannon409d8f22005-03-05 06:47:57 +00001086- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001087 (e.g., ``class C(): pass`` is no longer a syntax error).
1088 Patch #1176012 added support to the 'parser' module and 'compiler' package
1089 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001090
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001091- Patch #1115086: Support PY_LONGLONG in structmember.
1092
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001093- Bug #1155938: new style classes did not check that __init__() was
1094 returning None.
1095
Tim Petersecc6e6a2005-07-10 22:30:55 +00001096- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001097 ('\') with a specific error message.
1098
Martin v. Löwisff232d72005-03-03 09:24:38 +00001099- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1100
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001101- Bug #1124295: the __name__ attribute of file objects was
1102 inadvertently made inaccessible in restricted mode.
1103
Tim Petersecc6e6a2005-07-10 22:30:55 +00001104- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001105 an ferror() call.
1106
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001107- min() and max() now support key= arguments with the same meaning as in
1108 list.sort().
1109
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001110- The peephole optimizer now performs simple constant folding in expressions:
1111 (2+3) --> (5).
1112
Raymond Hettingera422c342005-01-11 03:03:27 +00001113- set and frozenset objects can now be marshalled. SF #1098985.
1114
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001115- Bug #1077106: Poor argument checking could cause memory corruption
1116 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001117
Jeremy Hyltonab630502005-02-04 18:44:06 +00001118- The parser did not complain about future statements in illegal
1119 positions. It once again reports a syntax error if a future
1120 statement occurs after anything other than a doc string.
1121
Neil Schemenauercf52c072005-08-12 17:34:58 +00001122- Change the %s format specifier for str objects so that it returns a
1123 unicode instance if the argument is not an instance of basestring and
1124 calling __str__ on the argument returns a unicode instance.
1125
Tim Petersf4e69282006-02-27 17:15:31 +00001126- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1127 current thread state when the auto-GIL-state machinery knows about
1128 it (since the thread state is being deleted, continuing to remember it
1129 can't help, but can hurt if another thread happens to get created with
1130 the same thread id).
1131
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001132Extension Modules
1133-----------------
1134
Georg Brandl43f08a82006-03-31 18:01:16 +00001135- Patch #1380952: fix SSL objects timing out on consecutive read()s

1138
Anthony Baxterfa869072006-03-20 05:21:58 +00001139- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1140 In addition, the existing ulaw code was updated.
1141
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001142- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001143 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001144
Neal Norwitz10be10c2006-03-16 06:50:13 +00001145- Everything under lib-old was removed. This includes the following modules:
1146 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001147 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001148 util, whatsound, whrandom, zmod
1149
1150- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1151
1152- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001153 is deprecated. The undocumented re.engine variable no longer exists.
1154
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001155- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1156 SS2 (single-shift 2) escape sequences correctly.
1157
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001158- The unicodedata module was updated to the 4.1 version of the Unicode
1159 database. The 3.2 version is still available as unicodedata.db_3_2_0
1160 for applications that require this specific version (such as IDNA).
1161
Neal Norwitzb62c4332006-03-04 18:35:47 +00001162- The timing module is no longer built by default. It was deprecated
1163 in PEP 4 in Python 2.0 or earlier.
1164
Guido van Rossum1968ad32006-02-25 22:38:04 +00001165- Patch 1433928: Added a new type, defaultdict, to the collections module.
1166 This uses the new __missing__ hook behavior added to dict (see above).
1167
Georg Brandldbd83392006-02-20 09:42:33 +00001168- Bug #854823: socketmodule now builds on Sun platforms even when
1169 INET_ADDRSTRLEN is not defined.
1170
Georg Brandlf4f44152006-02-18 22:29:33 +00001171- Patch #1393157: os.startfile() now has an optional argument to specify
1172 a "command verb" to invoke on the file.
1173
Neal Norwitz082b2df2006-02-07 07:04:46 +00001174- Bug #876637, prevent stack corruption when socket descriptor
1175 is larger than FD_SETSIZE.
1176
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001177- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1178 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1179 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1180
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001181- Patch #1422385: The nis module now supports access to domains other
1182 than the system default domain.
1183
Martin v. Löwis14694662006-02-03 12:54:16 +00001184- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1185 are reported, the limit on path name lengths is removed, and stat reports
1186 WindowsError now (instead of OSError).
1187
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001188- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
1189
Neal Norwitz62a21122006-01-25 05:21:55 +00001190- Bug #1413192, fix seg fault in bsddb if a transaction was deleted

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001322- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1323 been renamed to have only a single underscore prefix. This was done to
1324 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001325
Nick Coghlan43832302006-04-23 17:04:07 +00001326- PEP 338: new module runpy defines a run_module function to support
1327 executing modules which provide access to source code or a code object
1328 via the PEP 302 import mechanisms.
1329

1338 in attribute values.
1339
Anthony Baxterc51ee692006-04-01 00:57:31 +00001340- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001341 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001342 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001343 module will not be built.
1344
Tim Petersc17976e2006-04-01 00:26:53 +00001345- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1346 aren't officially supported here, and trying to use them will probably
1347 raise an exception some day. But dicts have been allowed, and "mostly
1348 worked", so support for them won't go away without warning.
1349
Georg Brandl338ef7d2006-03-31 18:42:16 +00001350- Bug #1445068: getpass.getpass() can now be given an explicit stream

1368
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001369- email 4.0 package now integrated. This is largely the same as the email 3.0
1370 package that was included in Python 2.3, except that PEP 8 module names are
1371 now used (e.g. mail.message instead of email.Message). The MIME classes
1372 have been moved to a subpackage (e.g. email.mime.text instead of
1373 email.MIMEText). The old names are still supported for now. Several
1374 deprecated Message methods have been removed and lots of bugs have been
1375 fixed. More details can be found in the email package documentation.
1376
Walter Dörwald40108c92006-03-27 08:15:44 +00001377- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1378 (a subclass of tuple) that provides incremental decoders and encoders
1379 (a way to use stateful codecs without the stream API). Python functions
1380 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1381 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1382 have been added.

1385 a ValueError instead of a StopIteration now (like file and cString.String do).
1386 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1387 called before (like file and StringIO.StringIO do).

Neal Norwitz338e7862005-12-23 21:27:46 +00001456- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
1457 LoadError as documented, instead of IOError. For compatibility,
1458 LoadError subclasses IOError.
1459
Brett Cannon3cbd0382005-12-16 22:49:23 +00001460- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001461 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1462 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1463 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1464 Ronald L. Rivest offered this advice for Python:
1465
1466 "The consensus of researchers in this area (at least as
1467 expressed at the NIST Hash Function Workshop 10/31/05),
1468 is that SHA-256 is a good choice for the time being, but
1469 that research should continue, and other alternatives may
1470 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001471
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001472- Added a subset of Fredrik Lundh's ElementTree package. Available

1514
Georg Brandl532efab2005-08-24 22:34:21 +00001515- Patch #848017: Make Cookie more RFC-compliant. Use CRLF as default output
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001516 separator and do not output trailing semicolon.
Georg Brandl532efab2005-08-24 22:34:21 +00001517
Georg Brandlb9256022005-08-24 18:46:39 +00001518- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
1519 ContentTooShortException, when the actually downloaded size does not
1520 match the Content-Length header.
1521

1525 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001526 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001527

1541
Georg Brandla4a8b822005-07-15 09:13:21 +00001542- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
1543 parameter, but uses the usual "kwargs=None".
1544
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001545- textwrap now processes text chunks at O(n) speed instead of O(n**2).

1549 to W3C name (404 -> 'Not Found'). RFE #1216944.
1550
Georg Brandl9e43acf2005-07-04 17:16:07 +00001551- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1552 as this can cause problems with apps closing all file descriptors.

1563
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001564- The tokenize module now detects and reports indentation errors.
1565 Bug #1224621.
1566
Raymond Hettinger68c04532005-06-10 11:05:19 +00001567- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001568 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001569 the generate_tokens() function now accepts a callable argument that
1570 terminates by raising StopIteration.
1571
Georg Brandl9166e1a2005-06-04 09:20:03 +00001572- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1575 component of the path.
1576
Skip Montanaro174dd222005-05-14 20:54:16 +00001577- Patch #1120353: The xmlrpclib module provides better, more transparent,
1578 support for datetime.{datetime,date,time} objects. With use_datetime set
1579 to True, applications shouldn't have to fiddle with the DateTime wrapper
1580 class at all.
1581
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001582- distutils.commands.upload was added to support uploading distribution
1583 files to PyPI.
1584
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001585- distutils.commands.register now encodes the data as UTF-8 before posting
1586 them to PyPI.
1587
Raymond Hettinger267b8682005-03-27 10:47:39 +00001588- decimal operator and comparison methods now return NotImplemented
1589 instead of raising a TypeError when interacting with other types. This
1590 allows other classes to implement __radd__ style methods and have them
1591 work as expected.
1592
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001593- Bug #1163325: Decimal infinities failed to hash. Attempting to
1594 hash a NaN raised an InvalidOperation instead of a TypeError.
1595
Tim Petersecc6e6a2005-07-10 22:30:55 +00001596- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001597 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1598

Martin v. Löwisa4dac402005-03-03 11:39:45 +00001608 profile.py if available.
1609
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001610- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1611

1616
Martin v. Löwise869eb12005-03-03 09:46:07 +00001617- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
1618

1620
Martin v. Löwisdf241532005-03-03 08:17:42 +00001621- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
1622

1630
Guido van Rossumd0641422005-02-03 15:01:24 +00001631- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1632 disables recursive traversal through instance attributes, which can
1633 be exploited in various ways.
1634
Tim Peterse3547fd2005-12-16 23:13:57 +00001635- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001636 flags on the HTTP listening socket.
1637
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001638- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1639 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1640
Tim Peterse3547fd2005-12-16 23:13:57 +00001641- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001642 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1643
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001644- Bug #1110478: Revert os.environ.update to do putenv again.

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001646- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1647
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001648- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1649
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001650- Enhancements to the csv module:
1651
1652 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001653 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001654 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001655 + Dialect parameter parsing has been re-implemented to improve error
1656 reporting.
1657 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1658 dictates.
1659 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001660 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001661 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001662 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1663 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001664 + reader now allows \r characters to be quoted (previously it only allowed
1665 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001666 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001667 + Dialect classes passed to the module are no longer instantiated by
1668 the module before being parsed (the former validation scheme required
1669 this, but the mechanism was unreliable).
1670 + The dialect registry now contains instances of the internal
1671 C-coded dialect type, rather than references to python objects.
1672 + the internal c-coded dialect type is now immutable.
1673 + register_dialect now accepts the same keyword dialect specifications
1674 as the reader and writer, allowing the user to register dialects
1675 without first creating a dialect class.
1676 + a configurable limit to the size of parsed fields has been added -
1677 previously, an unmatched quote character could result in the entire
1678 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001679 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001680 the parser field size limit (returning the former limit). The initial
1681 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001682 + A line_num attribute has been added to the reader object, which tracks
1683 the number of lines read from the source iterator. This is not
1684 the same as the number of records returned, as records can span
1685 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001686 + reader and writer objects were not being registered with the cyclic-GC.
1687 This has been fixed.
1688
Brett Cannone6539c42005-01-08 02:43:53 +00001689- _DummyThread objects in the threading module now delete self.__block that is
1690 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1691 lock primitives tend to be limited in number and thus should not be wasted on
1692 a _DummyThread object. Fixes bug #1089632.
1693
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001694- The imghdr module now detects Exif files.
1695
Raymond Hettinger6065d322004-12-20 23:51:53 +00001696- StringIO.truncate() now correctly adjusts the size attribute.
1697 (Bug #951915).
1698
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001699- locale.py now uses an updated locale alias table (built using
1700 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1701 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001702 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001703
Raymond Hettinger3557f422004-12-07 12:02:02 +00001704- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1705
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001706- the pickle module no longer accepts the deprecated None option in the
1707 args tuple returned by __reduce__().
1708
Brett Cannon84667c02004-12-07 03:25:18 +00001709- optparse now optionally imports gettext. This allows its use in setup.py.
1710
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001711- the pickle module no longer uses the deprecated bin parameter.
1712
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001713- the shelve module no longer uses the deprecated binary parameter.
1714
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001715- the pstats module no longer uses the deprecated ignore() method.
1716
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001717- the filecmp module no longer uses the deprecated use_statcache argument.
1718
Raymond Hettinger664347b2004-12-04 21:21:53 +00001719- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1720 extended or overridden by subclasses. Formerly, the subclassed method would
1721 be ignored by the rest of the module. (Bug #1078905).
1722
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001723- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001724 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001725
Walter Dörwald36733692004-12-22 12:50:50 +00001726- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1727 once when a size argument is given. This prevents a buffer overflow in the
1728 tokenizer with very long source lines.
1729
Barry Warsaw538561e2006-01-01 21:48:54 +00001730- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1731 immediately after creating the object, without any intervening
1732 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001733
Skip Montanaro05885812005-01-16 20:48:27 +00001734- The reconvert.quote function can now emit triple-quoted strings. The
1735 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001736
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001737- ``UserString.MutableString`` now supports negative indices in
1738 ``__setitem__`` and ``__delitem__``
1739
Greg Ward40407942005-03-05 02:53:17 +00001740- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1741 correctly.
1742
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001743- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1744 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1745 character even if the user has passed a size parameter to get a proper
1746 line ending. Remove the special handling of a "\r\n" that has been split
1747 between two lines.
1748
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001749- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1750 about illegal code points. The codec now supports PEP 293 style error
1751 handlers.
1752
Walter Dörwald78a78b02005-09-01 12:04:29 +00001753- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001754 from the input stream, so that the output is a byte string in the correct
1755 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001756
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001757- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1758 considering it exactly like a '*'.
1759
Walter Dörwald007f8df2005-10-09 19:42:27 +00001760- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1761 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001762
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001763- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1764
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001765- Patch #1413711: Certain patterns of differences were making difflib
1766 touch the recursion limit.
1767
Walter Dörwald58917a62006-03-31 15:26:22 +00001768- Bug #947906: An object oriented interface has been added to the calendar
1769 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001770 called as a script (e.g. via ``python -mcalendar``). Localized month and
1771 weekday names can be ouput (even if an exotic encoding is used) using
1772 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001773
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001774Build
1775-----
1776
Neal Norwitz602d3392006-03-31 08:21:40 +00001777- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1778 by using -mieee gcc option.
1779

1781
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001782- Build support for Win64-AMD64 was added.
1783
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001784- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1785
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001786- Patch #881820: look for openpty and forkpty also in libbsd.
1787
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001788- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1789 The zlib module is now builtin on Windows.
1790
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001791- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1792
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001793- Bug #1189330: configure did not correctly determine the necessary
1794 value of LINKCC if python was built with GCC 4.0.
1795
Trent Mick8321b422005-07-26 02:29:21 +00001796- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1797 vulnerability in zlib 1.2.1 and 1.2.2.
1798
Brett Cannon08cd5982005-04-24 22:26:38 +00001799- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1800 flags that change binary compatibility. Changes were also made to
1801 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001802 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001803
Bob Ippolitoed233462005-03-29 13:47:59 +00001804- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1805 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1806 no longer exists). This configure patch makes things right.
1807
Martin v. Löwise2713be2005-03-08 15:03:08 +00001808- Bug #1158607: Build with --disable-unicode again.
1809
Brett Cannon46d96232005-02-16 00:07:19 +00001810- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1811 defined. Discovered as a result of not being able to build on OS X.
1812
Brett Cannon516592f2004-12-07 00:42:59 +00001813- setup.py now uses the directories specified in LDFLAGS using the -L option
1814 and in CPPFLAGS using the -I option for adding library and include
1815 directories, respectively, for compiling extension modules against. This has
1816 led to the core being compiled using the values in CPPFLAGS. It also removes
1817 the need for the special-casing of both DarwinPorts and Fink for darwin since
1818 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1819 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1820 Fink, ``-I/opt/local/include`` for DarwinPorts).
1821
Brett Cannon43802422005-02-10 20:48:03 +00001822- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1823 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1824 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1825 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001827C API
1828-----
1829
Tim Petersc9d78aa2006-03-26 23:27:58 +00001830- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1831 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1832 is obtained via the ``PyObject_`` family, it must be released via the
1833 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1834 always been officially true, but when Python's small-object allocator was
1835 introduced, an attempt was made to cater to a few extension modules
1836 discovered at the time that obtained memory via ``PyObject_New`` but
1837 released it via ``PyMem_DEL``. It's years later, and if such code still
1838 exists it will fail now (probably with segfaults, but calling wrong
1839 low-level memory management functions can yield many symptoms).
1840
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001841- Added a C API for set and frozenset objects.
1842
Raymond Hettinger66517482004-12-03 11:45:13 +00001843- Removed PyRange_New().
1844
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001845- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1846 mapping argument now. This string is used as a mapping table. Byte values
1847 greater than the length of the string and 0xFFFE are treated as undefined
1848 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00001854- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001855
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001856- Patch #1276356: New resource "urlfetch" is implemented. This enables
1857 even impatient people to run tests that require remote files.
