12Core and builtins
13-----------------
14
Martin v. Löwisab2f8f72006-08-09 07:57:39 +000015- Bug #1536021: __hash__ may now return long int; the final hash
16 value is obtained by invoking hash on the long int.
17
Thomas Hellerab1049c2006-08-08 17:37:00 +000018- Bug #1536786: buffer comparison could emit a RuntimeWarning.

22
Thomas Heller74d36f02006-08-04 18:17:40 +000023- On Windows, the PyErr_Warn function is now exported from
24 the Python dll again.
25
Neal Norwitz4ffedad2006-08-04 04:58:47 +000026- Bug #1191458: tracing over for loops now produces a line event
27 on each iteration. Fixing this problem required changing the .pyc
28 magic number. This means that .pyc files generated before 2.5c1
29 will be regenerated.
30
Neal Norwitz0cbd8052006-08-04 05:09:28 +000031- Bug #1333982: string/number constants were inappropriately stored
32 in the byte code and co_consts even if they were not used, ie
33 immediately popped off the stack.
34
Georg Brandle9462c72006-08-04 18:03:37 +000035- Fixed a reference-counting problem in property().

51-----------------
52
Bob Ippolitoe6c9f982006-08-04 23:59:21 +000053- Bug #1530559, struct.pack raises TypeError where it used to convert.
54 Passing float arguments to struct.pack when integers are expected
55 now triggers a DeprecationWarning.
56
Neal Norwitzff4b63b2006-08-04 04:50:21 +000057
58Tests

60

62
Andrew MacIntyre16ee33a2006-08-06 12:37:03 +000063- test_threading now skips testing alternate thread stack sizes on
64 platforms that don't support changing thread stack size.
65
Neal Norwitzff4b63b2006-08-04 04:50:21 +000066

Tim Peters4643c2f2006-08-10 22:45:34 +000081C API
82-----
83
84- Bug #1069160. Internal correctness changes were made to
85 ``PyThreadState_SetAsyncExc()``. A test case was added, and

Fred Drake53912162006-07-29 13:22:49 +000094What's New in Python 2.5 beta 3?
95================================
Neal Norwitza1f10902006-07-12 07:28:29 +000096
Anthony Baxter5d32a9f2006-08-02 07:43:09 +000097*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +000098
99Core and builtins
100-----------------
101
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000102- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t, it previously
103 returned a long (see PEP 353).
104
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000105- Bug #1515471: string.replace() accepts character buffers again.
106
Neal Norwitz07aadb12006-07-30 06:55:48 +0000107- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
108 This provides the proper warning for struct.pack().
109 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
110
Neal Norwitz0d62a062006-07-30 06:53:31 +0000111- Patch #1531113: Fix augmented assignment with yield expressions.
112 Also fix a SystemError when trying to assign to yield expressions.
113
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000114- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
115 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
116 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
117 excessive filesystem operations during imports.
118
Tim Petersbc24eee2006-07-27 01:14:53 +0000119- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
120 operations on signed longs that are formally undefined by C.
121 Unfortunately, at least one compiler now cares about that, so complicated
122 the code to make that compiler happy again.
123
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000124- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
125
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000126- Patch #1232023: Stop including current directory in search
127 path on Windows.
128
Neal Norwitze1fdb322006-07-21 05:32:28 +0000129- Fix some potential crashes found with failmalloc.
130
Neal Norwitze7563102006-07-17 01:00:16 +0000131- Fix warnings reported by Klocwork's static analysis tool.
132
Neal Norwitz84be93b2006-07-16 01:50:38 +0000133- Bug #1512814, Fix incorrect lineno's when code within a function
134 had more than 255 blank lines.
135
Georg Brandl9dceedb2006-07-12 15:31:17 +0000136- Patch #1521179: Python now accepts the standard options ``--help`` and
137 ``--version`` as well as ``/?`` on Windows.
138
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000139- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000140 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000141 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000142
Tim Peters112aad32006-07-19 00:03:19 +0000143- Bug #1524317: Compiling Python ``--without-threads`` failed.
144 The Python core compiles again then, and, in a build without threads, the
145 new ``sys._current_frames()`` returns a dictionary with one entry,
146 mapping the faux "thread id" 0 to the current frame.
147
Ronald Oussoren3075e162006-07-25 20:28:55 +0000148- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000149
Ronald Oussoren3075e162006-07-25 20:28:55 +0000150
Neal Norwitza1f10902006-07-12 07:28:29 +0000151Library
152-------
153
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000154- Correction of patch #1455898: In the mbcs decoder, set final=False
155 for stream decoder, but final=True for the decode function.
156
Georg Brandl07fec3a2006-08-01 18:49:24 +0000157- os.urandom no longer masks unrelated exceptions like SystemExit or
158 KeyboardInterrupt.
159
Tim Peters4643c2f2006-08-10 22:45:34 +0000160- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000161 shutil.copytree on Windows
162
Georg Brandle34ac7c2006-07-30 11:07:23 +0000163- Bug #1002398: The documentation for os.path.sameopenfile now correctly
164 refers to file descriptors, not file objects.
165
Fred Drakefbdeaad2006-07-29 16:56:15 +0000166- Rename of the xml package to xmlcore, and the import hackery done to
167 make it appear at both names, has been removed. Bug #1511497,
168 #1513611, and probably others.
169
Georg Brandledd9b0d2006-07-29 09:33:26 +0000170- Bug #1441397: The compiler module now recognizes module and function
171 docstrings correctly as it did in Python 2.4.
172
Tim Peters6f681472006-07-27 23:44:37 +0000173- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
174 lost that tests are sorted by name before being run. This rarely
175 matters for well-written tests, but can create baffling symptoms if
176 side effects from one test to the next affect outcomes. ``DocTestFinder``
177 has been changed to sort the list of tests it returns.
178
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000179- The distutils version has been changed to 2.5.0, and are now kept
180 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000181
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000182- Bug #978833: Really close underlying socket in _socketobject.close.
183
Georg Brandl0619a322006-07-26 07:40:17 +0000184- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
185 with title().
186
Georg Brandlcf0c1722006-07-26 07:23:32 +0000187- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
188 to recursive calls and call it with the failing package name.
189
Martin v. Löwis0b483032006-07-25 09:53:12 +0000190- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
191
Georg Brandlc13c34c2006-07-24 14:09:56 +0000192- Patch #1515343: Fix printing of deprecated string exceptions with a
193 value in the traceback module.
194
Greg Ward48fae7a2006-07-23 16:05:51 +0000195- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
196
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000197- Patch #1524429: Use repr() instead of backticks in Tkinter again.
198
Brett Cannoncaebe222006-07-18 04:41:36 +0000199- Bug #1520914: Change time.strftime() to accept a zero for any position in its
200 argument tuple. For arguments where zero is illegal, the value is forced to
201 the minimum value that is correct. This is to support an undocumented but
202 common way people used to fill in inconsequential information in the time
203 tuple pre-2.4.
204
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000205- Patch #1220874: Update the binhex module for Mach-O.
206
Barry Warsawb110bad2006-07-21 14:51:07 +0000207- The email package has improved RFC 2231 support, specifically for
208 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
209 (name*0=<blah>) parameter continuations. This may change the types of
210 values returned from email.message.Message.get_param() and friends.
211 Specifically in some cases where non-encoded continuations were used,
212 get_param() used to return a 3-tuple of (None, None, string) whereas now it
213 will just return the string (since non-encoded continuations don't have
214 charset and language parts).
215
216 Also, whereas % values were decoded in all parameter continuations, they are
217 now only decoded in encoded parameter parts.
218
Ronald Oussoren3075e162006-07-25 20:28:55 +0000219- Bug #1517990: IDLE keybindings on MacOS X now work correctly
220
221- Bug #1517996: IDLE now longer shows the default Tk menu when a
222 path browser, class browser or debugger is the frontmost window on MacOS X
223
Barry Warsaw00decd72006-07-27 23:43:15 +0000224- Patch #1520294: Support for getset and member descriptors in types.py,
225 inspect.py, and pydoc.py. Specifically, this allows for querying the type
226 of an object against these built-in types and more importantly, for getting
227 their docstrings printed in the interactive interpreter's help() function.

232
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000233- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
234 a socket operation on a socket with a timeout, the exception will be
235 caught correctly. Previously, the exception was not caught.
236
Thomas Heller1393d6a2006-07-28 21:43:20 +0000237- Patch #1529514: The _ctypes extension is now compiled on more
238 openbsd target platforms.
239
Tim Peters9cab5932006-07-28 00:30:00 +0000240- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
241 a memory leak, affecting pickles and deep copies.
242
Tim Petersbc24eee2006-07-27 01:14:53 +0000243- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000246- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
247
Thomas Hellerce049a02006-07-14 17:51:14 +0000248- Patch #1521817: Index range checking on ctypes arrays containing
249 exactly one element enabled again. This allows iterating over these
250 arrays, without the need to check the array size before.
251
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000252- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000253 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000254 /dev/null in certain cases; this is now fixed.
255
Thomas Heller47d7a062006-07-12 08:43:47 +0000256- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
257 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000258
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000259- Because of a misspelled preprocessor symbol, ctypes was always
260 compiled without thread support; this is now fixed.
261
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000262- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
263 methods now allow their database parameter to be None as the
264 sleepycat API allows.
265
Matt Flemingec926502006-07-28 11:27:27 +0000266- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
267 bluetooth API compared with Linux and FreeBSD.
268
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000269Tests
270-----
271
272- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
273 how long the test file should take to play. Now accepts taking 2.93 secs
274 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
275
Georg Brandl4793aa32006-07-28 18:31:39 +0000276- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
277 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
278 run via ``regrtest.py``. Now they do.

287
288- PythonLauncher now works correctly when the path to the script contains
289 characters that are treated specially by the shell (such as quotes).
290
291- Bug #1527397: PythonLauncher now launches scripts with the working directory
292 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000293 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000294 expect.

303-----------------
304
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000305- Bug #1441486: The literal representation of -(sys.maxint - 1)

307
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000308- Bug #1501934: The scope of global variables that are locally assigned
309 using augmented assignment is now correctly determined.
310
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000311- Bug #927248: Recursive method-wrapper objects can now safely
312 be released.
313
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000314- Bug #1417699: Reject locale-specific decimal point in float()
315 and atof().
316
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000317- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
318 omit a default "error" argument for NULL pointer. This allows
319 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000320
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000321- Bug #1519018: 'as' is now validated properly in import statements.
322
Neal Norwitz28746ab2006-07-09 22:14:42 +0000323- On 64 bit systems, int literals that use less than 64 bits are
324 now ints rather than longs.
325
Neal Norwitzed657552006-07-10 00:04:44 +0000326- Bug #1512814, Fix incorrect lineno's when code at module scope
327 started after line 256.
328
Tim Peters32a83612006-07-10 21:08:24 +0000329- New function ``sys._current_frames()`` returns a dict mapping thread
330 id to topmost thread stack frame. This is for expert use, and is
331 especially useful for debugging application deadlocks. The functionality
332 was previously available in Fazal Majid's ``threadframe`` extension
333 module, but it wasn't possible to do this in a wholly threadsafe way from
334 an extension.

Brett Cannon53ab5b72006-06-22 16:49:14 +0000382- Bug #1510580: The 'warnings' module improperly required that a Warning
383 category be either a types.ClassType and a subclass of Warning. The proper
384 check is just that it is a subclass with Warning as the documentation states.
385
Georg Brandlad29e632006-06-21 17:45:17 +0000386- The compiler module now correctly compiles the new try-except-finally

Tim Peters112aad32006-07-19 00:03:19 +0000401- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
402 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
403 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000404
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000405- Assigning None to pointer type fields in ctypes structures possible
406 overwrote the wrong fields, this is fixed now.
407
408- Fixed a segfault in _ctypes when ctypes.wintypes were imported
409 on non-Windows platforms.
410
411- Bug #1518190: The ctypes.c_void_p constructor now accepts any
412 integer or long, without range checking.
413
414- Patch #1517790: It is now possible to use custom objects in the ctypes
415 foreign function argtypes sequence as long as they provide a from_param
416 method, no longer is it required that the object is a ctypes type.
417

436
Tim Peters32a83612006-07-10 21:08:24 +0000437- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000438 Previously, the slight difference could cause compilation errors of the
439 'zlib' module on systems with more than one version of zlib.
440
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000441- The MSI compileall step was fixed to also support a TARGETDIR

472Core and builtins
473-----------------
474
Georg Brandla56b9152006-06-19 06:35:54 +0000475- Patch #1507676: Error messages returned by invalid abstract object operations
476 (such as iterating over an integer) have been improved and now include the
477 type of the offending object to help with debugging.
478
Brett Cannonea3912b2006-06-13 21:46:41 +0000479- Bug #992017: A classic class that defined a __coerce__() method that returned
480 its arguments swapped would infinitely recurse and segfault the interpreter.
481
Neal Norwitz909eb122006-06-12 02:13:21 +0000482- Fix the socket tests so they can be run concurrently.
483
Neal Norwitzb9845e72006-06-12 02:11:18 +0000484- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000485 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000486
Brett Cannon22565aa2006-06-09 22:31:23 +0000487- Bug #532646: object.__call__() will continue looking for the __call__
488 attribute on objects until one without one is found. This leads to recursion
489 when you take a class and set its __call__ attribute to an instance of the
490 class. Originally fixed for classic classes, but this fix is for new-style.
491 Removes the infinite_rec_3 crasher.
492
Georg Brandl24250812006-06-09 18:45:48 +0000493- The string and unicode methods startswith() and endswith() now accept
494 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
495
Brett Cannonde3b0522006-06-08 17:00:45 +0000496- Buffer objects, at the C level, never used the char buffer
497 implementation even when the char buffer for the wrapped object was
498 explicitly requested (originally returned the read or write buffer).
499 Now a TypeError is raised if the char buffer is not present but is
500 requested.
501
Georg Brandlddbaa662006-06-04 21:56:52 +0000502- Patch #1346214: Statements like "if 0: suite" are now again optimized
503 away like they were in Python 2.4.
504
Georg Brandlb7c8f542006-05-27 12:30:25 +0000505- Builtin exceptions are now full-blown new-style classes instead of
506 instances pretending to be classes, which speeds up exception handling
507 by about 80% in comparison to 2.5a2.
508
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000509- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
510 Unicode 4.1.
511
Georg Brandlf4ef1162006-05-26 18:03:31 +0000512- Patch #921466: sys.path_importer_cache is now used to cache valid and
513 invalid file paths for the built-in import machinery which leads to
514 fewer open calls on startup.
515
Tim Peters696cf432006-05-24 21:10:40 +0000516- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
517 of-2 bases. The largest speedup is for inputs with about 1000 decimal
518 digits. Conversion from non-power-of-2 bases remains quadratic-time in
519 the number of input digits (it was and remains linear-time for bases
520 2, 4, 8, 16 and 32).
521
Tim Petersb713ec22006-05-23 18:45:30 +0000522- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
523 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
524 an integer close to ``sys.maxint``. This was repaired by patch
525 #1335972, which also gives a nice speedup.
526
Richard Jonescebbefc2006-05-23 18:28:17 +0000527- Patch #1337051: reduced size of frame objects.
528
529- PyErr_NewException now accepts a tuple of base classes as its
530 "base" parameter.
531
Richard Jones7c88dcc2006-05-23 10:37:38 +0000532- Patch #876206: function call speedup by retaining allocated frame
533 objects.
534
Georg Brandl7b90e162006-05-18 07:01:27 +0000535- Bug #1462152: file() now checks more thoroughly for invalid mode
536 strings and removes a possible "U" before passing the mode to the
537 C library function.
538
Neal Norwitz1004a532006-05-15 07:17:23 +0000539- Patch #1488312, Fix memory alignment problem on SPARC in unicode
540
Neal Norwitz373f0a72006-05-15 07:04:36 +0000541- Bug #1487966: Fix SystemError with conditional expression in assignment
542
Martin v. Löwis879768d2006-05-11 13:28:43 +0000543- WindowsError now has two error code attributes: errno, which carries
544 the error values from errno.h, and winerror, which carries the error
545 values from winerror.h. Previous versions put the winerror.h values
546 (from GetLastError()) into the errno attribute.
547
Martin v. Löwis77736712006-05-04 05:51:03 +0000548- Patch #1475845: Raise IndentationError for unexpected indent.
549
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000550- Patch #1479181: split open() and file() from being aliases for each other.
551
Tim Peters44bd9862006-06-01 13:49:23 +0000552- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
553 methods were always silently ignored by dictionaries when comparing keys.
554 They are now passed through (except when using the C API function
555 ``PyDict_GetItem()``, whose semantics did not change).
556
557- Bug #1456209: In some obscure cases it was possible for a class with a
558 custom ``__eq__()`` method to confuse dict internals when class instances
559 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
560 No, you don't have any code that did this ;-)

573
Nick Coghlanc649ec52006-05-29 12:43:05 +0000574- Patch #1478788 (modified version): The functional extension module has
575 been renamed to _functools and a functools Python wrapper module added.
576 This provides a home for additional function related utilities that are
577 not specifically about functional programming. See PEP 309.
578
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000579- Patch #1493701: performance enhancements for struct module.

590 (up to the system limit of 32K characters).
591
592- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
593 As a result, these functions now raise WindowsError instead of OSError.
594
Tim Peters7a822da2006-05-25 21:50:17 +0000595- ``time.clock()`` on Win64 should use the high-performance Windows
596 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
597 Windows platforms).
598
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000599- Calling Tk_Init twice is refused if the first call failed as that
600 may deadlock.
601
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000602- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
603 accept it without potentially using an uninitialized pointer.
604
605- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
606 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smith506f7b52006-06-15 08:52:32 +0000623- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000624 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000625 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
626 database calls that would previously deadlock. [SF python bug #775414]
627
Vinay Sajip28e57612006-07-01 10:45:20 +0000628- Patch #1446489: add support for the ZIP64 extensions to zipfile.

637 functions.
638
Martin v. Löwis3798da02006-06-17 18:44:27 +0000639- Patch #812986: Update turtle output even if not tracing.

647 classes.
648
Georg Brandl83cc0d02006-06-14 08:50:03 +0000649- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
650 mime.types file for determining MIME types.
651
Georg Brandl2605ca82006-06-14 06:08:31 +0000652- Bug #1339007: Shelf objects now don't raise an exception in their
653 __del__ method when initialization failed.
654
Martin v. Löwisd8251432006-06-14 05:21:04 +0000655- Patch #1455898: The MBCS codec now supports the incremental mode for
656 double-byte encodings.
657
Tim Peters43898b42006-06-14 04:09:25 +0000658- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
659 guarantee that adjacent triples in the return list always describe
660 non-adjacent blocks. Previously, a pair of matching blocks could end
661 up being described by multiple adjacent triples that formed a partition
662 of the matching pair.
663
Greg Ward0e0c9f42006-06-11 16:24:11 +0000664- Bug #1498146: fix optparse to handle Unicode strings in option help,
665 description, and epilog.
666
Greg Wardd1c797e2006-06-11 14:42:41 +0000667- Bug #1366250: minor optparse documentation error.
668
Greg Ward7f547402006-06-11 00:40:49 +0000669- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
670 clarify docs.
671
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000672- The wsgiref package has been added to the standard library.
673
Nick Coghlan676725d2006-06-08 13:54:49 +0000674- The functions update_wrapper() and wraps() have been added to the functools
675 module. These make it easier to copy relevant metadata from the original
676 function when writing wrapper functions.
677
Tim Petersd6a9eef2006-06-05 01:48:21 +0000678- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
679 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000680
Martin v. Löwis3f767792006-06-04 19:36:28 +0000681- Patch #1359618: Speed up charmap encoder by using a trie structure
682 for lookup.
683
Tim Petersd609b1a2006-06-02 23:22:51 +0000684- The functions in the ``pprint`` module now sort dictionaries by key
685 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
686 if and only if its display required more than one line, although that
687 wasn't documented. The new behavior increases predictability; e.g.,
688 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
689
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000690- Patch #1497027: try HTTP digest auth before basic auth in urllib2
691 (thanks for J. J. Lee).
692
Georg Brandl2b330372006-05-28 20:23:12 +0000693- Patch #1496206: improve urllib2 handling of passwords with respect to
694 default HTTP and HTTPS ports.
695
George Yoshidaf3c65de2006-05-28 16:39:09 +0000696- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
697
Bob Ippolito7298f272006-05-23 18:43:47 +0000698- Patch #1281707: speed up gzip.readline.
699
Georg Brandlb89316f2006-05-17 15:51:16 +0000700- Patch #1180296: Two new functions were added to the locale module:
701 format_string() to get the effect of "format % items" but locale-aware,
702 and currency() to format a monetary number with currency sign.
703
Georg Brandle3a25832006-05-17 14:56:04 +0000704- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
705 and several features added, such as speed and geometry control.
706
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000707- Patch #1488881: add support for external file objects in bz2 compressed
708 tarfiles.
709
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000710- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
711 stdout arguments, making it possible to redirect input and output
712 for remote debugging.
713
714- Patch #1484695: Update the tarfile module to version 0.8. This fixes
715 a couple of issues, notably handling of long file names using the
716 GNU LONGNAME extension.
717
718- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
719 new flag when ``name`` is already the name of an option flag.
720
721- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
722 package.
723
724- Patch #1472854: make the rlcompleter.Completer class usable on non-
725 UNIX platforms.
726
727- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
728
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000729- Bug #1472827: correctly escape newlines and tabs in attribute values in
730 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000760What's New in Python 2.5 alpha 2?
761=================================
762
763*Release date: 27-APR-2006*
764
765Core and builtins
766-----------------
767
Thomas Heller1b046642006-04-18 18:51:06 +0000768- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
769 by converting these apis from macros into exported functions again:
770
771 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
772 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
773 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
774 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
775 PyRun_String Py_CompileString
776
Martin v. Löwis45294a92006-04-18 06:24:08 +0000777- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
778
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000779- All uses of PyStructSequence_InitType have been changed to initialize
780 the type objects only once, even if the interpreter is initialized
781 multiple times.
782
Neal Norwitz61546162006-04-14 05:20:28 +0000783- Bug #1454485, array.array('u') could crash the interpreter. This was
784 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
785 to unicode when it didn't make sense. 'u#' now requires a unicode string.
786
787- Py_UNICODE is unsigned. It was always documented as unsigned, but
788 due to a bug had a signed value in previous versions.
789
Tim Peters3a5e8b12006-04-11 01:44:07 +0000790- Patch #837242: ``id()`` of any Python object always gives a positive
791 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
792 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000793 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000794 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000795
Tim Peters3a5e8b12006-04-11 01:44:07 +0000796 def __hash__(self):
797 return id(self) # WRONG
798
799 because a hash result must be a (short) Python int but it was always
800 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000801 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000802 was always usable as a hash value before this patch. That's no longer
803 necessarily so.
804
805- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000806 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000807 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000808 #1454844)
809
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000810- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
811 involving generators that have paused outside of any ``try`` or ``with``
812 blocks. (In 2.5a1, a paused generator that was part of a reference
813 cycle could not be garbage collected, regardless of whether it was
814 paused in a ``try`` or ``with`` block.)

831 a temporary db (file=None) with the 'n' flag to truncate on open.
832
833- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
834 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000835
Armin Rigoa9017c32006-04-19 11:50:27 +0000836- Patch #1062014: AF_UNIX sockets under Linux have a special

840-------
841
Peter Astrand7d1d4362006-07-14 14:04:45 +0000842- Bug #1223937: subprocess.CalledProcessError reports the exit status
843 of the process using the returncode attribute, instead of
844 abusing errno.
845
Tim Peters711bf302006-04-25 03:31:36 +0000846- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes

848 or exception is ignored).
849
Nick Coghlanda2268f2006-04-24 04:37:15 +0000850- Fixed contextlib.nested to cope with exceptions being raised and
851 caught inside exit handlers.
852
Greg Wardab05edc2006-04-23 03:47:58 +0000853- Updated optparse module to Optik 1.5.1 (allow numeric constants in
854 hex, octal, or binary; add ``append_const`` action; keep going if
855 gettext cannot be imported; added ``OptionParser.destroy()`` method;
856 added ``epilog`` for better help generation).
857
Tim Peters21fbd572006-04-21 21:18:10 +0000858- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
859 called from a thread spawned as a side effect of importing a module.
860
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000861- The pydoc module now supports documenting packages contained in
862 .zip or .egg files.
863
864- The pkgutil module now has several new utility functions, such
865 as ``walk_packages()`` to support working with packages that are either
866 in the filesystem or zip files.
867
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000868- The mailbox module can now modify and delete messages from
869 mailboxes, in addition to simply reading them. Thanks to Gregory
870 K. Johnson for writing the code, and to the 2005 Google Summer of
871 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000872
Tim Petersc7605f22006-04-17 21:12:33 +0000873- The ``__del__`` method of class ``local`` in module ``_threading_local``
874 returned before accomplishing any of its intended cleanup.
875

884
Phillip J. Eby47032112006-04-11 01:07:43 +0000885- The warnings, linecache, inspect, traceback, site, and doctest modules
886 were updated to work correctly with modules imported from zipfiles or

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000909- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
910 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000911 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000912 CXX from --with-cxx-main, see description in README.
913
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000914- Patch #1429775: Link extension modules with the shared libpython.

923-----
924
Nick Coghlanda2268f2006-04-24 04:37:15 +0000925- test_contextlib now checks contextlib.nested can cope with exceptions
926 being raised and caught inside exit handlers.
927
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000928- test_cmd_line now checks operation of the -m and -c command switches
929
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000930- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
931 it separately and by hand. It also wasn't cleaning up its changes to
932 the current Decimal context.
933
Thomas Woutersabd08882006-04-26 15:53:30 +0000934- regrtest.py now has a -M option to run tests that test the new limits of
935 containers, on 64-bit architectures. Running these tests is only sensible
936 on 64-bit machines with more than two gigabytes of memory. The argument

946-------------
947
Tim Petersb06d28c2006-05-12 01:57:59 +0000948- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
949
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000950- PEP 343: Added Context Types section to the library reference
951 and attempted to bring other PEP 343 related documentation into
952 line with the implementation and/or python-dev discussions.
953
Tim Peters8dc73d22006-04-24 02:03:16 +0000954- Bug #1337990: clarified that ``doctest`` does not support examples
955 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000963Core and builtins
964-----------------
965
Nick Coghlan43832302006-04-23 17:04:07 +0000966- PEP 338: -m command line switch now delegates to runpy.run_module
967 allowing it to support modules in packages and zipfiles
968
Martin v. Löwisc661b882006-04-20 04:54:23 +0000969- On Windows, .DLL is not an accepted file name extension for
970 extension modules anymore; extensions are only found if they
971 end in .PYD.
972
Martin v. Löwisea62d252006-04-03 10:56:49 +0000973- Bug #1421664: sys.stderr.encoding is now set to the same value as
974 sys.stdout.encoding.
975
Neal Norwitz92e212f2006-04-03 04:48:37 +0000976- __import__ accepts keyword arguments.
977
Georg Brandlccadf842006-03-31 18:54:53 +0000978- Patch #1460496: round() now accepts keyword arguments.
979
Anthony Baxter262c00a2006-03-30 10:53:17 +0000980- Fixed bug #1459029 - unicode reprs were double-escaped.
981
Hye-Shik Changd478f342006-03-23 12:32:36 +0000982- Patch #1396919: The system scope threads are reenabled on FreeBSD
983 5.4 and later versions.
984
Neal Norwitze98ccf62006-03-23 05:39:47 +0000985- Bug #1115379: Compiling a Unicode string with an encoding declaration
986 now gives a SyntaxError.
987
Georg Brandlabd1ff82006-03-18 07:59:59 +0000988- Previously, Python code had no easy way to access the contents of a
989 cell object. Now, a ``cell_contents`` attribute has been added
990 (closes patch #1170323).
991
Tim Peterscf79aac2006-03-16 01:14:46 +0000992- Patch #1123430: Python's small-object allocator now returns an arena to
993 the system ``free()`` when all memory within an arena becomes unused
994 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
995 freed. Some applications will see a drop in virtual memory size now,
996 especially long-running applications that, from time to time, temporarily
997 use a large number of small objects. Note that when Python returns an
998 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000999 platform C library will in turn return that memory to the operating system.
1000 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001001 appears to be effective at least on Microsoft C and gcc-based systems.
1002 Thanks to Evan Jones for hard work and patience.
1003
Georg Brandl533ff6f2006-03-08 18:09:27 +00001004- Patch #1434038: property() now uses the getter's docstring if there is
1005 no "doc" argument given. This makes it possible to legitimately use
1006 property() as a decorator to produce a read-only property.
1007
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001008- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1009 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1010 of requiring an int or long in slicing and a few other contexts, enabling
1011 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1012
Neal Norwitz995acdf2006-03-07 05:01:00 +00001013- Fixed various bugs reported by Coverity's Prevent tool.
1014
Brett Cannonbf364092006-03-01 04:25:17 +00001015- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1016 new exception base class, BaseException, which has a new message attribute.
1017 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1018 Raising a string exception now raises a DeprecationWarning.
1019
Thomas Woutersfb609f42006-02-28 16:37:25 +00001020- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1021 explicitly relative, using 'from .module import name' to mean 'from the same
1022 package as this module is in. Imports without dots still default to the
1023 old relative-then-absolute, unless 'from __future__ import
1024 absolute_import' is used.
1025
Brett Cannona7446e32006-02-27 23:39:10 +00001026- Properly check if 'warnings' raises an exception (usually when a filter set
1027 to "error" is triggered) when raising a warning for raising string
1028 exceptions.
1029
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001030- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001031 The name was removed from Include/code.h.
1032
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001033- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001034
Guido van Rossum1968ad32006-02-25 22:38:04 +00001035- Patch 1433928:
1036 - The copy module now "copies" function objects (as atomic objects).
1037 - dict.__getitem__ now looks for a __missing__ hook before raising
1038 KeyError.
1039
Tim Peters84ef21c2006-02-28 20:39:06 +00001040- PEP 343: with statement implemented. Needs ``from __future__ import
1041 with_statement``. Use of 'with' as a variable will generate a warning.
1042 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001043 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001044 The following objects have __context__ methods:
1045 - The built-in file type.
1046 - The thread.LockType type.
1047 - The following types defined by the threading module:
1048 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1049 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001050
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001051- Fix the encodings package codec search function to only search
1052 inside its own package. Fixes problem reported in patch #1433198.
1053
1054 Note: Codec packages should implement and register their own
1055 codec search function. PEP 100 has the details.
1056
Tim Peters9ea89d22006-06-04 03:26:02 +00001057- PEP 353: Using ``Py_ssize_t`` as the index type.
1058
1059- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1060 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1061 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1062 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1063 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001064
Neal Norwitzfc76d632006-01-10 06:03:13 +00001065- Patch #1400181, fix unicode string formatting to not use the locale.
1066 This is how string objects work. u'%f' could use , instead of .
1067 for the decimal point. Now both strings and unicode always use periods.
1068
Neal Norwitz671b9e32006-01-09 07:07:12 +00001069- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1070 configure would break checking curses.h.
1071
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001072- Bug #959576: The pwd module is now builtin. This allows Python to be
1073 built on UNIX platforms without $HOME set.
1074
Neal Norwitzc10978f2005-12-19 06:07:16 +00001075- Bug #1072182, fix some potential problems if characters are signed.
1076
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001077- Bug #889500, fix line number on SyntaxWarning for global declarations.
1078
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001079- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1080
Neal Norwitze7214a12005-12-18 05:03:17 +00001081- Support for converting hex strings to floats no longer works.
1082 This was not portable. float('0x3') now raises a ValueError.
1083
Barry Warsaw2a38a862005-12-18 01:27:35 +00001084- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001085 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001086 is now displayed in interactive prompt banner.
1087
Georg Brandlfa166682005-12-17 21:45:17 +00001088- Implementation of PEP 341 - Unification of try/except and try/finally.
1089 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001090 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001091
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001092- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1093 now encodes backslash correctly.
1094
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001095- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1096
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001097- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001098 and long longs.
1099
Neal Norwitz67715f02005-11-09 06:59:35 +00001100- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001101 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001102 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001103
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001104- Replaced most Unicode charmap codecs with new ones using the
1105 new Unicode translate string feature in the builtin charmap
1106 codec; the codecs were created from the mapping tables available
1107 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1108 encodings now include a mapping for the Apple logo)
1109
Tim Peterse3547fd2005-12-16 23:13:57 +00001110- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001111
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001112- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001113
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001114- A new AST parser implementation was completed. The abstract
1115 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001116 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001117
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001118- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001119 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1120
Neal Norwitz708e51a2005-10-03 04:48:15 +00001121- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1122
Neal Norwitz11bd1192005-10-03 00:54:56 +00001123- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1124 Provide a warning when a directory is passed on the command line.
1125
Neal Norwitz40d37812005-10-02 01:48:49 +00001126- Fix segfault with invalid coding.
1127
1128- SF bug #772896: unknown encoding results in MemoryError.
1129
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001130- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001131 supported a __len__() method which evaluated to False when the iterator
1132 was empty.
1133
Guido van Rossum630db602005-09-20 18:49:54 +00001134- On 64-bit platforms, when __len__() returns a value that cannot be
1135 represented as a C int, raise OverflowError.
1136
Skip Montanarof8948ca2005-09-19 03:54:46 +00001137- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001138 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001139
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001140- SF bug #893549: parsing keyword arguments was broken with a few format
1141 codes.
1142
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001143- Changes donated by Elemental Security to make it work on AIX 5.3
1144 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1145 bug #105470: test_pwd fails on 64bit system (Opteron).
1146
Guido van Rossum539c6622005-09-14 17:49:54 +00001147- Changes donated by Elemental Security to make it work on HP-UX 11 on
1148 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1149
Georg Brandl4550b8d2005-08-26 06:43:52 +00001150- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001151 (fixes bug #1119418).
1152
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001153- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1154
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001155- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1156 exceptions that cause a function to exit.
1157
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001158- The implementation of set() and frozenset() was revised to use its
1159 own internal data structure. Memory consumption is reduced by 1/3
1160 and there are modest speed-ups as well. The API is unchanged.
1161
Tim Petersde7990b2005-07-17 23:45:23 +00001162- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1163
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001164- SF bug #1229429: PyObject_CallMethod failed to decrement some
1165 reference counts in some error exit cases.
1166
Tim Petersecc6e6a2005-07-10 22:30:55 +00001167- SF bug #1185883: Python's small-object memory allocator took over
1168 a block managed by the platform C library whenever a realloc specified
1169 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001170 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001171 portable way to copy data from the C-managed block into Python's
1172 small-object space without risking a memory fault. Python's small-object
1173 realloc now leaves such blocks under the control of the platform C
1174 realloc.
1175
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001176- SF bug #1232517: An overflow error was not detected properly when
1177 attempting to convert a large float to an int in os.utime().
1178
Raymond Hettinger3296e692005-06-29 23:29:56 +00001179- SF bug #1224347: hex longs now print with lowercase letters just
1180 like their int counterparts.
1181
Michael W. Hudson188d4362005-06-20 16:52:57 +00001182- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1183 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1184 interpreter states; back out that fix and do a better job (see
1185 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1186 for a longer write-up of the problem).
1187
Michael W. Hudsondf888462005-06-03 14:41:55 +00001188- SF patch #1180995: marshal now uses a binary format by default when
1189 serializing floats.
1190
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001191- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1192 the routines that promise to produce IEEE 754 binary representations
1193 of floats now simply copy bytes around.
1194
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001195- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1196 278.
1197
Brett Cannonc3647ac2005-04-26 03:45:26 +00001198- patch #1109424: int, long, float, complex, and unicode now check for the
1199 proper magic slot for type conversions when subclassed. Previously the
1200 magic slot was ignored during conversion. Semantics now match the way
1201 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001202 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001203 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001204 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001205
Barry Warsawc8d907c2005-04-19 23:43:40 +00001206- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1207 NULL, now raise an AttributeError when attempting to set or delete the
1208 attribute. Previously a TypeError was raised, but this was inconsistent
1209 with the equivalent pure-Python implementation.
1210
Michael W. Hudson774479c2005-04-18 08:46:17 +00001211- It is now safe to call PyGILState_Release() before
1212 PyEval_InitThreads() (note that if there is reason to believe there
1213 are multiple threads around you still must call PyEval_InitThreads()
1214 before using the Python API; this fix is for extension modules that
1215 have no way of knowing if Python is multi-threaded yet).
1216
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001217- Typing Ctrl-C whilst raw_input() was waiting in a build with threads

Brett Cannonf4189912005-04-09 02:30:16 +00001229 (e.g., ``class C(): pass`` is no longer a syntax error).
1230 Patch #1176012 added support to the 'parser' module and 'compiler' package
1231 (thanks to logistix for that added support).

Jeremy Hyltonab630502005-02-04 18:44:06 +00001260- The parser did not complain about future statements in illegal
1261 positions. It once again reports a syntax error if a future
1262 statement occurs after anything other than a doc string.
1263
Neil Schemenauercf52c072005-08-12 17:34:58 +00001264- Change the %s format specifier for str objects so that it returns a
1265 unicode instance if the argument is not an instance of basestring and
1266 calling __str__ on the argument returns a unicode instance.
1267
Tim Petersf4e69282006-02-27 17:15:31 +00001268- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1269 current thread state when the auto-GIL-state machinery knows about
1270 it (since the thread state is being deleted, continuing to remember it
1271 can't help, but can hurt if another thread happens to get created with
1272 the same thread id).

1480 in attribute values.
1481
Anthony Baxterc51ee692006-04-01 00:57:31 +00001482- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001483 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001484 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001485 module will not be built.
1486
Tim Petersc17976e2006-04-01 00:26:53 +00001487- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1488 aren't officially supported here, and trying to use them will probably
1489 raise an exception some day. But dicts have been allowed, and "mostly
1490 worked", so support for them won't go away without warning.
1491
Georg Brandl338ef7d2006-03-31 18:42:16 +00001492- Bug #1445068: getpass.getpass() can now be given an explicit stream
1493 argument to specify where to write the prompt.
1494
Georg Brandl22ec80b2006-03-31 18:25:44 +00001495- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1501 key to be used for signing the uploaded code.
1502
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001503- Queue.Queue objects now support .task_done() and .join() methods
1504 to make it easier to monitor when daemon threads have completed
1505 processing all enqueued tasks. Patch #1455676.
1506
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001507- popen2.Popen objects now preserve the command in a .cmd attribute.
1508
Thomas Hellerc61c0492006-03-22 10:09:27 +00001509- Added the ctypes ffi package.
1510
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001511- email 4.0 package now integrated. This is largely the same as the email 3.0
1512 package that was included in Python 2.3, except that PEP 8 module names are
1513 now used (e.g. mail.message instead of email.Message). The MIME classes
1514 have been moved to a subpackage (e.g. email.mime.text instead of
1515 email.MIMEText). The old names are still supported for now. Several
1516 deprecated Message methods have been removed and lots of bugs have been
1517 fixed. More details can be found in the email package documentation.
1518
Walter Dörwald40108c92006-03-27 08:15:44 +00001519- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1520 (a subclass of tuple) that provides incremental decoders and encoders
1521 (a way to use stateful codecs without the stream API). Python functions
1522 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1523 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1524 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001525
Walter Dörwald067db482006-03-15 22:17:27 +00001526- Patch #1359365: Calling next() on a closed StringIO.String object raises
1527 a ValueError instead of a StopIteration now (like file and cString.String do).
1528 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1529 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001530
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001531- A regrtest option -w was added to re-run failed tests in verbose mode.

1534 interpreter to exit.
1535
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001536- The function get_count() has been added to the gc module, and gc.collect()
1537 grew an optional 'generation' argument.
1538
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00001539- A library msilib to generate Windows Installer files, and a distutils

1543 and helpful context managers nested() and closing().
1544
Martin v. Löwis415ed932006-02-27 19:56:30 +00001545- The compiler package now supports future imports after the module docstring.

Martin v. Löwis3e865952006-01-24 15:51:21 +00001579 specifications, raises IOErrors when proxies for unsupported protocols
1580 are defined, and uses the https proxy on https redirections.

1599 LoadError as documented, instead of IOError. For compatibility,
1600 LoadError subclasses IOError.
1601
Brett Cannon3cbd0382005-12-16 22:49:23 +00001602- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001603 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1604 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1605 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1606 Ronald L. Rivest offered this advice for Python:
1607
1608 "The consensus of researchers in this area (at least as
1609 expressed at the NIST Hash Function Workshop 10/31/05),
1610 is that SHA-256 is a good choice for the time being, but
1611 that research should continue, and other alternatives may
1612 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001613
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001614- Added a subset of Fredrik Lundh's ElementTree package. Available

1667 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001668 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001669

1683
Georg Brandla4a8b822005-07-15 09:13:21 +00001684- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
1685 parameter, but uses the usual "kwargs=None".
1686
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001687- textwrap now processes text chunks at O(n) speed instead of O(n**2).

1691 to W3C name (404 -> 'Not Found'). RFE #1216944.
1692
Georg Brandl9e43acf2005-07-04 17:16:07 +00001693- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1694 as this can cause problems with apps closing all file descriptors.

1707 Bug #1224621.
1708
Raymond Hettinger68c04532005-06-10 11:05:19 +00001709- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001710 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001711 the generate_tokens() function now accepts a callable argument that
1712 terminates by raising StopIteration.
1713
Georg Brandl9166e1a2005-06-04 09:20:03 +00001714- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1717 component of the path.
1718
Skip Montanaro174dd222005-05-14 20:54:16 +00001719- Patch #1120353: The xmlrpclib module provides better, more transparent,
1720 support for datetime.{datetime,date,time} objects. With use_datetime set
1721 to True, applications shouldn't have to fiddle with the DateTime wrapper
1722 class at all.
1723
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001724- distutils.commands.upload was added to support uploading distribution

1733 work as expected.
1734
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001735- Bug #1163325: Decimal infinities failed to hash. Attempting to

1770
Raymond Hettingerbab41432005-02-05 01:31:19 +00001771- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1772
Guido van Rossumd0641422005-02-03 15:01:24 +00001773- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1774 disables recursive traversal through instance attributes, which can
1775 be exploited in various ways.
1776
Tim Peterse3547fd2005-12-16 23:13:57 +00001777- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001778 flags on the HTTP listening socket.
1779
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001780- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1781 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1782
Fred Drakefbdeaad2006-07-29 16:56:15 +00001783- Patches #893642, #1039083: add allow_none, encoding arguments to
1784 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001785

1787
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001788- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1789
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001790- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1791
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001792- Enhancements to the csv module:
1793
1794 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001795 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001796 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001797 + Dialect parameter parsing has been re-implemented to improve error
1798 reporting.
1799 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1800 dictates.
1801 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001802 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001803 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001804 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1805 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001806 + reader now allows \r characters to be quoted (previously it only allowed
1807 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001808 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001809 + Dialect classes passed to the module are no longer instantiated by
1810 the module before being parsed (the former validation scheme required
1811 this, but the mechanism was unreliable).
1812 + The dialect registry now contains instances of the internal
1813 C-coded dialect type, rather than references to python objects.
1814 + the internal c-coded dialect type is now immutable.
1815 + register_dialect now accepts the same keyword dialect specifications
1816 as the reader and writer, allowing the user to register dialects
1817 without first creating a dialect class.
1818 + a configurable limit to the size of parsed fields has been added -
1819 previously, an unmatched quote character could result in the entire
1820 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001821 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001822 the parser field size limit (returning the former limit). The initial
1823 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001824 + A line_num attribute has been added to the reader object, which tracks
1825 the number of lines read from the source iterator. This is not
1826 the same as the number of records returned, as records can span
1827 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001828 + reader and writer objects were not being registered with the cyclic-GC.
1829 This has been fixed.
1830
Brett Cannone6539c42005-01-08 02:43:53 +00001831- _DummyThread objects in the threading module now delete self.__block that is
1832 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1833 lock primitives tend to be limited in number and thus should not be wasted on
1834 a _DummyThread object. Fixes bug #1089632.
1835
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001836- The imghdr module now detects Exif files.
1837
Raymond Hettinger6065d322004-12-20 23:51:53 +00001838- StringIO.truncate() now correctly adjusts the size attribute.
1839 (Bug #951915).
1840
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001841- locale.py now uses an updated locale alias table (built using
1842 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1843 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001844 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001845
Raymond Hettinger3557f422004-12-07 12:02:02 +00001846- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1847
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001848- the pickle module no longer accepts the deprecated None option in the
1849 args tuple returned by __reduce__().
1850
Brett Cannon84667c02004-12-07 03:25:18 +00001851- optparse now optionally imports gettext. This allows its use in setup.py.
1852
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001853- the pickle module no longer uses the deprecated bin parameter.
1854
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001855- the shelve module no longer uses the deprecated binary parameter.
1856
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001857- the pstats module no longer uses the deprecated ignore() method.
1858
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001859- the filecmp module no longer uses the deprecated use_statcache argument.
1860
Raymond Hettinger664347b2004-12-04 21:21:53 +00001861- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1862 extended or overridden by subclasses. Formerly, the subclassed method would
1863 be ignored by the rest of the module. (Bug #1078905).
1864
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001865- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001866 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001867
Walter Dörwald36733692004-12-22 12:50:50 +00001868- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1869 once when a size argument is given. This prevents a buffer overflow in the
1870 tokenizer with very long source lines.
1871
Barry Warsaw538561e2006-01-01 21:48:54 +00001872- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1873 immediately after creating the object, without any intervening
1874 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001875
Skip Montanaro05885812005-01-16 20:48:27 +00001876- The reconvert.quote function can now emit triple-quoted strings. The
1877 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001878
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001879- ``UserString.MutableString`` now supports negative indices in
1880 ``__setitem__`` and ``__delitem__``
1881
Greg Ward40407942005-03-05 02:53:17 +00001882- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1883 correctly.
1884
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001885- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1886 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1887 character even if the user has passed a size parameter to get a proper
1888 line ending. Remove the special handling of a "\r\n" that has been split
1889 between two lines.
1890
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001891- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1892 about illegal code points. The codec now supports PEP 293 style error
1893 handlers.
1894
Walter Dörwald78a78b02005-09-01 12:04:29 +00001895- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001896 from the input stream, so that the output is a byte string in the correct
1897 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001898
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001899- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1900 considering it exactly like a '*'.
1901
Walter Dörwald007f8df2005-10-09 19:42:27 +00001902- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1903 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001904
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001905- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1906
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001907- Patch #1413711: Certain patterns of differences were making difflib
1908 touch the recursion limit.
1909
Walter Dörwald58917a62006-03-31 15:26:22 +00001910- Bug #947906: An object oriented interface has been added to the calendar
1911 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001912 called as a script (e.g. via ``python -mcalendar``). Localized month and
1913 weekday names can be ouput (even if an exotic encoding is used) using
1914 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001915

1917-----
1918
Neal Norwitz602d3392006-03-31 08:21:40 +00001919- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1920 by using -mieee gcc option.
1921
Martin v. Löwis86d66262006-02-17 08:40:11 +00001922- Patch #1432345: Make python compile on DragonFly.
1923
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001924- Build support for Win64-AMD64 was added.
1925
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001926- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1927
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001928- Patch #881820: look for openpty and forkpty also in libbsd.
1929
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001930- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1931 The zlib module is now builtin on Windows.
1932
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001933- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1934
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001935- Bug #1189330: configure did not correctly determine the necessary
1936 value of LINKCC if python was built with GCC 4.0.
1937
Trent Mick8321b422005-07-26 02:29:21 +00001938- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1939 vulnerability in zlib 1.2.1 and 1.2.2.
1940
Brett Cannon08cd5982005-04-24 22:26:38 +00001941- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1942 flags that change binary compatibility. Changes were also made to
1943 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001944 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001945
Bob Ippolitoed233462005-03-29 13:47:59 +00001946- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1947 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1948 no longer exists). This configure patch makes things right.
1949
Martin v. Löwise2713be2005-03-08 15:03:08 +00001950- Bug #1158607: Build with --disable-unicode again.
1951
Brett Cannon46d96232005-02-16 00:07:19 +00001952- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1953 defined. Discovered as a result of not being able to build on OS X.
1954
Brett Cannon516592f2004-12-07 00:42:59 +00001955- setup.py now uses the directories specified in LDFLAGS using the -L option
1956 and in CPPFLAGS using the -I option for adding library and include
1957 directories, respectively, for compiling extension modules against. This has
1958 led to the core being compiled using the values in CPPFLAGS. It also removes
1959 the need for the special-casing of both DarwinPorts and Fink for darwin since
1960 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1961 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1962 Fink, ``-I/opt/local/include`` for DarwinPorts).
1963
Brett Cannon43802422005-02-10 20:48:03 +00001964- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1965 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1966 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1967 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001969C API
1970-----
1971
Tim Petersc9d78aa2006-03-26 23:27:58 +00001972- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1973 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1974 is obtained via the ``PyObject_`` family, it must be released via the
1975 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1976 always been officially true, but when Python's small-object allocator was
1977 introduced, an attempt was made to cater to a few extension modules
1978 discovered at the time that obtained memory via ``PyObject_New`` but
1979 released it via ``PyMem_DEL``. It's years later, and if such code still
1980 exists it will fail now (probably with segfaults, but calling wrong
1981 low-level memory management functions can yield many symptoms).
1982
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001983- Added a C API for set and frozenset objects.
1984
Raymond Hettinger66517482004-12-03 11:45:13 +00001985- Removed PyRange_New().
1986
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001987- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1988 mapping argument now. This string is used as a mapping table. Byte values
1989 greater than the length of the string and 0xFFFE are treated as undefined
1990 mappings.
