13-----------------
14
Thomas Heller74d36f02006-08-04 18:17:40 +000015- On Windows, the PyErr_Warn function is now exported from
16 the Python dll again.
17
Neal Norwitz4ffedad2006-08-04 04:58:47 +000018- Bug #1191458: tracing over for loops now produces a line event
19 on each iteration. Fixing this problem required changing the .pyc
20 magic number. This means that .pyc files generated before 2.5c1
21 will be regenerated.
22
Neal Norwitz0cbd8052006-08-04 05:09:28 +000023- Bug #1333982: string/number constants were inappropriately stored
24 in the byte code and co_consts even if they were not used, ie
25 immediately popped off the stack.
26
Georg Brandle9462c72006-08-04 18:03:37 +000027- Fixed a reference-counting problem in property().

Fred Drake53912162006-07-29 13:22:49 +000064What's New in Python 2.5 beta 3?
65================================
Neal Norwitza1f10902006-07-12 07:28:29 +000066
Anthony Baxter5d32a9f2006-08-02 07:43:09 +000067*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +000068
69Core and builtins
70-----------------
71
Neal Norwitzc5e060d2006-08-02 06:14:22 +000072- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t, it previously
73 returned a long (see PEP 353).
74
Neal Norwitzf71ec5a2006-07-30 06:57:04 +000075- Bug #1515471: string.replace() accepts character buffers again.
76
Neal Norwitz07aadb12006-07-30 06:55:48 +000077- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
78 This provides the proper warning for struct.pack().
79 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
80
Neal Norwitz0d62a062006-07-30 06:53:31 +000081- Patch #1531113: Fix augmented assignment with yield expressions.
82 Also fix a SystemError when trying to assign to yield expressions.
83
Phillip J. Ebyf7575d02006-07-28 21:12:07 +000084- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
85 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
86 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
87 excessive filesystem operations during imports.
88
Tim Petersbc24eee2006-07-27 01:14:53 +000089- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
90 operations on signed longs that are formally undefined by C.
91 Unfortunately, at least one compiler now cares about that, so complicated
92 the code to make that compiler happy again.
93
Martin v. Löwis982e9fe2006-07-24 12:54:17 +000094- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
95
Martin v. Löwisd22968a2006-07-24 11:54:53 +000096- Patch #1232023: Stop including current directory in search
97 path on Windows.
98
Neal Norwitze1fdb322006-07-21 05:32:28 +000099- Fix some potential crashes found with failmalloc.
100
Neal Norwitze7563102006-07-17 01:00:16 +0000101- Fix warnings reported by Klocwork's static analysis tool.
102
Neal Norwitz84be93b2006-07-16 01:50:38 +0000103- Bug #1512814, Fix incorrect lineno's when code within a function
104 had more than 255 blank lines.
105
Georg Brandl9dceedb2006-07-12 15:31:17 +0000106- Patch #1521179: Python now accepts the standard options ``--help`` and
107 ``--version`` as well as ``/?`` on Windows.
108
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000109- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000110 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000111 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000112
Tim Peters112aad32006-07-19 00:03:19 +0000113- Bug #1524317: Compiling Python ``--without-threads`` failed.
114 The Python core compiles again then, and, in a build without threads, the
115 new ``sys._current_frames()`` returns a dictionary with one entry,
116 mapping the faux "thread id" 0 to the current frame.
117
Ronald Oussoren3075e162006-07-25 20:28:55 +0000118- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000119
Ronald Oussoren3075e162006-07-25 20:28:55 +0000120
Neal Norwitza1f10902006-07-12 07:28:29 +0000121Library
122-------
123
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000124- Correction of patch #1455898: In the mbcs decoder, set final=False
125 for stream decoder, but final=True for the decode function.
126
Georg Brandl07fec3a2006-08-01 18:49:24 +0000127- os.urandom no longer masks unrelated exceptions like SystemExit or
128 KeyboardInterrupt.
129
Martin v. Löwis4e678382006-07-30 13:00:31 +0000130- Bug #1525866: Don't copy directory stat times in
131 shutil.copytree on Windows
132
Georg Brandle34ac7c2006-07-30 11:07:23 +0000133- Bug #1002398: The documentation for os.path.sameopenfile now correctly
134 refers to file descriptors, not file objects.
135
Fred Drakefbdeaad2006-07-29 16:56:15 +0000136- Rename of the xml package to xmlcore, and the import hackery done to
137 make it appear at both names, has been removed. Bug #1511497,
138 #1513611, and probably others.
139
Georg Brandledd9b0d2006-07-29 09:33:26 +0000140- Bug #1441397: The compiler module now recognizes module and function
141 docstrings correctly as it did in Python 2.4.
142
Tim Peters6f681472006-07-27 23:44:37 +0000143- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
144 lost that tests are sorted by name before being run. This rarely
145 matters for well-written tests, but can create baffling symptoms if
146 side effects from one test to the next affect outcomes. ``DocTestFinder``
147 has been changed to sort the list of tests it returns.
148
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000149- The distutils version has been changed to 2.5.0, and are now kept
150 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000151
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000152- Bug #978833: Really close underlying socket in _socketobject.close.
153
Georg Brandl0619a322006-07-26 07:40:17 +0000154- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
155 with title().
156
Georg Brandlcf0c1722006-07-26 07:23:32 +0000157- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
158 to recursive calls and call it with the failing package name.
159
Martin v. Löwis0b483032006-07-25 09:53:12 +0000160- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
161
Georg Brandlc13c34c2006-07-24 14:09:56 +0000162- Patch #1515343: Fix printing of deprecated string exceptions with a
163 value in the traceback module.
164
Greg Ward48fae7a2006-07-23 16:05:51 +0000165- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
166
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000167- Patch #1524429: Use repr() instead of backticks in Tkinter again.
168
Brett Cannoncaebe222006-07-18 04:41:36 +0000169- Bug #1520914: Change time.strftime() to accept a zero for any position in its
170 argument tuple. For arguments where zero is illegal, the value is forced to
171 the minimum value that is correct. This is to support an undocumented but
172 common way people used to fill in inconsequential information in the time
173 tuple pre-2.4.
174
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000175- Patch #1220874: Update the binhex module for Mach-O.
176
Barry Warsawb110bad2006-07-21 14:51:07 +0000177- The email package has improved RFC 2231 support, specifically for
178 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
179 (name*0=<blah>) parameter continuations. This may change the types of
180 values returned from email.message.Message.get_param() and friends.
181 Specifically in some cases where non-encoded continuations were used,
182 get_param() used to return a 3-tuple of (None, None, string) whereas now it
183 will just return the string (since non-encoded continuations don't have
184 charset and language parts).
185
186 Also, whereas % values were decoded in all parameter continuations, they are
187 now only decoded in encoded parameter parts.
188
Ronald Oussoren3075e162006-07-25 20:28:55 +0000189- Bug #1517990: IDLE keybindings on MacOS X now work correctly
190
191- Bug #1517996: IDLE now longer shows the default Tk menu when a
192 path browser, class browser or debugger is the frontmost window on MacOS X
193
Barry Warsaw00decd72006-07-27 23:43:15 +0000194- Patch #1520294: Support for getset and member descriptors in types.py,
195 inspect.py, and pydoc.py. Specifically, this allows for querying the type
196 of an object against these built-in types and more importantly, for getting
197 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +0000200Extension Modules
201-----------------
202
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000203- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
204 a socket operation on a socket with a timeout, the exception will be
205 caught correctly. Previously, the exception was not caught.
206
Thomas Heller1393d6a2006-07-28 21:43:20 +0000207- Patch #1529514: The _ctypes extension is now compiled on more
208 openbsd target platforms.
209
Tim Peters9cab5932006-07-28 00:30:00 +0000210- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
211 a memory leak, affecting pickles and deep copies.
212
Tim Petersbc24eee2006-07-27 01:14:53 +0000213- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000214 Paul Eggert.
215
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000216- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
217
Thomas Hellerce049a02006-07-14 17:51:14 +0000218- Patch #1521817: Index range checking on ctypes arrays containing
219 exactly one element enabled again. This allows iterating over these
220 arrays, without the need to check the array size before.
221
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000222- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000223 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000224 /dev/null in certain cases; this is now fixed.
225
Thomas Heller47d7a062006-07-12 08:43:47 +0000226- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
227 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000228
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000229- Because of a misspelled preprocessor symbol, ctypes was always
230 compiled without thread support; this is now fixed.
231
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000232- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
233 methods now allow their database parameter to be None as the
234 sleepycat API allows.
235
Matt Flemingec926502006-07-28 11:27:27 +0000236- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
237 bluetooth API compared with Linux and FreeBSD.
238
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000239Tests
240-----
241
242- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
243 how long the test file should take to play. Now accepts taking 2.93 secs
244 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
245
Georg Brandl4793aa32006-07-28 18:31:39 +0000246- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
247 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
248 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000249

253- Bug #1439538: Drop usage of test -e in configure as it is not portable.
254
Ronald Oussoren26cad082006-08-01 21:00:57 +0000255Mac
256---
257
258- PythonLauncher now works correctly when the path to the script contains
259 characters that are treated specially by the shell (such as quotes).
260
261- Bug #1527397: PythonLauncher now launches scripts with the working directory
262 set to the directory that contains the script instead of the user home
263 directory. That latter was an implementation accident and not what users
264 expect.

273-----------------
274
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000275- Bug #1441486: The literal representation of -(sys.maxint - 1)
276 again evaluates to a int object, not a long.
277
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000278- Bug #1501934: The scope of global variables that are locally assigned
279 using augmented assignment is now correctly determined.
280
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000281- Bug #927248: Recursive method-wrapper objects can now safely
282 be released.
283
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000284- Bug #1417699: Reject locale-specific decimal point in float()
285 and atof().
286
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000287- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
288 omit a default "error" argument for NULL pointer. This allows
289 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000290
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000291- Bug #1519018: 'as' is now validated properly in import statements.
292
Neal Norwitz28746ab2006-07-09 22:14:42 +0000293- On 64 bit systems, int literals that use less than 64 bits are
294 now ints rather than longs.
295
Neal Norwitzed657552006-07-10 00:04:44 +0000296- Bug #1512814, Fix incorrect lineno's when code at module scope
297 started after line 256.
298
Tim Peters32a83612006-07-10 21:08:24 +0000299- New function ``sys._current_frames()`` returns a dict mapping thread
300 id to topmost thread stack frame. This is for expert use, and is
301 especially useful for debugging application deadlocks. The functionality
302 was previously available in Fazal Majid's ``threadframe`` extension
303 module, but it wasn't possible to do this in a wholly threadsafe way from
304 an extension.

311
Martin v. Löwis06c68b82006-07-10 22:11:28 +0000312- Patch #1519566: Update turtle demo, make begin_fill idempotent.
313
Tim Peters32a83612006-07-10 21:08:24 +0000314- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000315 environment variable to be set in order to the SDK environment
316 for finding the compiler, include files, etc.

321
Thomas Woutersadd19112006-07-05 11:03:49 +0000322- string.Template() now correctly handles tuple-values. Previously,
323 multi-value tuples would raise an exception and single-value tuples would

339 is created.
340
Martin v. Löwis7596e832006-07-01 15:33:37 +0000341- Bug #1513223: .close() of a _socketobj now releases the underlying
342 socket again, which then gets closed as it becomes unreferenced.
343

351
Brett Cannon53ab5b72006-06-22 16:49:14 +0000352- Bug #1510580: The 'warnings' module improperly required that a Warning
353 category be either a types.ClassType and a subclass of Warning. The proper
354 check is just that it is a subclass with Warning as the documentation states.
355
Georg Brandlad29e632006-06-21 17:45:17 +0000356- The compiler module now correctly compiles the new try-except-finally
357 statement (bug #1509132).
358
Neal Norwitz60373cd2006-06-22 06:30:50 +0000359- The wsgiref package is now installed properly on Unix.
360

362 shutdown when fileConfig() was called multiple times.
363
Gerhard Häring762fbd32006-07-02 17:48:30 +0000364- The sqlite3 module did cut off data from the SQLite database at the first
365 null character before sending it to a custom converter. This has been fixed
366 now.

369-----------------
370
Tim Peters112aad32006-07-19 00:03:19 +0000371- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
372 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
373 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000374
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000375- Assigning None to pointer type fields in ctypes structures possible
376 overwrote the wrong fields, this is fixed now.
377
378- Fixed a segfault in _ctypes when ctypes.wintypes were imported
379 on non-Windows platforms.
380
381- Bug #1518190: The ctypes.c_void_p constructor now accepts any
382 integer or long, without range checking.
383
384- Patch #1517790: It is now possible to use custom objects in the ctypes
385 foreign function argtypes sequence as long as they provide a from_param
386 method, no longer is it required that the object is a ctypes type.
387
388- The '_ctypes' extension module now works when Python is configured
389 with the --without-threads option.
390
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000391- Bug #1513646: os.access on Windows now correctly determines write
392 access, again.
393
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000394- Bug #1512695: cPickle.loads could crash if it was interrupted with

406
Tim Peters32a83612006-07-10 21:08:24 +0000407- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000408 Previously, the slight difference could cause compilation errors of the
409 'zlib' module on systems with more than one version of zlib.
410
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000411- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +0000440
441Core and builtins
442-----------------
443
Georg Brandla56b9152006-06-19 06:35:54 +0000444- Patch #1507676: Error messages returned by invalid abstract object operations
445 (such as iterating over an integer) have been improved and now include the
446 type of the offending object to help with debugging.
447
Brett Cannonea3912b2006-06-13 21:46:41 +0000448- Bug #992017: A classic class that defined a __coerce__() method that returned
449 its arguments swapped would infinitely recurse and segfault the interpreter.
450
Neal Norwitz909eb122006-06-12 02:13:21 +0000451- Fix the socket tests so they can be run concurrently.
452
Neal Norwitzb9845e72006-06-12 02:11:18 +0000453- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000454 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000455
Brett Cannon22565aa2006-06-09 22:31:23 +0000456- Bug #532646: object.__call__() will continue looking for the __call__
457 attribute on objects until one without one is found. This leads to recursion
458 when you take a class and set its __call__ attribute to an instance of the
459 class. Originally fixed for classic classes, but this fix is for new-style.
460 Removes the infinite_rec_3 crasher.
461
Georg Brandl24250812006-06-09 18:45:48 +0000462- The string and unicode methods startswith() and endswith() now accept
463 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
464
Brett Cannonde3b0522006-06-08 17:00:45 +0000465- Buffer objects, at the C level, never used the char buffer
466 implementation even when the char buffer for the wrapped object was
467 explicitly requested (originally returned the read or write buffer).
468 Now a TypeError is raised if the char buffer is not present but is
469 requested.
470
Georg Brandlddbaa662006-06-04 21:56:52 +0000471- Patch #1346214: Statements like "if 0: suite" are now again optimized
472 away like they were in Python 2.4.
473
Georg Brandlb7c8f542006-05-27 12:30:25 +0000474- Builtin exceptions are now full-blown new-style classes instead of
475 instances pretending to be classes, which speeds up exception handling
476 by about 80% in comparison to 2.5a2.
477
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000478- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
479 Unicode 4.1.
480
Georg Brandlf4ef1162006-05-26 18:03:31 +0000481- Patch #921466: sys.path_importer_cache is now used to cache valid and
482 invalid file paths for the built-in import machinery which leads to
483 fewer open calls on startup.
484
Tim Peters696cf432006-05-24 21:10:40 +0000485- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
486 of-2 bases. The largest speedup is for inputs with about 1000 decimal
487 digits. Conversion from non-power-of-2 bases remains quadratic-time in
488 the number of input digits (it was and remains linear-time for bases
489 2, 4, 8, 16 and 32).
490
Tim Petersb713ec22006-05-23 18:45:30 +0000491- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
492 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
493 an integer close to ``sys.maxint``. This was repaired by patch
494 #1335972, which also gives a nice speedup.
495
Richard Jonescebbefc2006-05-23 18:28:17 +0000496- Patch #1337051: reduced size of frame objects.
497
498- PyErr_NewException now accepts a tuple of base classes as its
499 "base" parameter.
500
Richard Jones7c88dcc2006-05-23 10:37:38 +0000501- Patch #876206: function call speedup by retaining allocated frame
502 objects.
503
Georg Brandl7b90e162006-05-18 07:01:27 +0000504- Bug #1462152: file() now checks more thoroughly for invalid mode
505 strings and removes a possible "U" before passing the mode to the
506 C library function.
507
Neal Norwitz1004a532006-05-15 07:17:23 +0000508- Patch #1488312, Fix memory alignment problem on SPARC in unicode
509
Neal Norwitz373f0a72006-05-15 07:04:36 +0000510- Bug #1487966: Fix SystemError with conditional expression in assignment
511
Martin v. Löwis879768d2006-05-11 13:28:43 +0000512- WindowsError now has two error code attributes: errno, which carries
513 the error values from errno.h, and winerror, which carries the error
514 values from winerror.h. Previous versions put the winerror.h values
515 (from GetLastError()) into the errno attribute.
516
Martin v. Löwis77736712006-05-04 05:51:03 +0000517- Patch #1475845: Raise IndentationError for unexpected indent.
518
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000519- Patch #1479181: split open() and file() from being aliases for each other.
520
Tim Peters44bd9862006-06-01 13:49:23 +0000521- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
522 methods were always silently ignored by dictionaries when comparing keys.
523 They are now passed through (except when using the C API function
524 ``PyDict_GetItem()``, whose semantics did not change).
525
526- Bug #1456209: In some obscure cases it was possible for a class with a
527 custom ``__eq__()`` method to confuse dict internals when class instances
528 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
529 No, you don't have any code that did this ;-)

542
Nick Coghlanc649ec52006-05-29 12:43:05 +0000543- Patch #1478788 (modified version): The functional extension module has
544 been renamed to _functools and a functools Python wrapper module added.
545 This provides a home for additional function related utilities that are
546 not specifically about functional programming. See PEP 309.
547

559 (up to the system limit of 32K characters).
560
561- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
562 As a result, these functions now raise WindowsError instead of OSError.
563
Tim Peters7a822da2006-05-25 21:50:17 +0000564- ``time.clock()`` on Win64 should use the high-performance Windows
565 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
566 Windows platforms).
567
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000568- Calling Tk_Init twice is refused if the first call failed as that
569 may deadlock.
570
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000571- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
572 accept it without potentially using an uninitialized pointer.
573
574- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods

Vinay Sajip28e57612006-07-01 10:45:20 +0000593 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000594 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
595 database calls that would previously deadlock. [SF python bug #775414]

Tim Peters43898b42006-06-14 04:09:25 +0000627- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
628 guarantee that adjacent triples in the return list always describe
629 non-adjacent blocks. Previously, a pair of matching blocks could end
630 up being described by multiple adjacent triples that formed a partition
631 of the matching pair.
632
Greg Ward0e0c9f42006-06-11 16:24:11 +0000633- Bug #1498146: fix optparse to handle Unicode strings in option help,
634 description, and epilog.
635
Greg Wardd1c797e2006-06-11 14:42:41 +0000636- Bug #1366250: minor optparse documentation error.
637
Greg Ward7f547402006-06-11 00:40:49 +0000638- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
639 clarify docs.
640
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000641- The wsgiref package has been added to the standard library.
642
Nick Coghlan676725d2006-06-08 13:54:49 +0000643- The functions update_wrapper() and wraps() have been added to the functools
644 module. These make it easier to copy relevant metadata from the original
645 function when writing wrapper functions.
646
Tim Petersd6a9eef2006-06-05 01:48:21 +0000647- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
648 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000649
Martin v. Löwis3f767792006-06-04 19:36:28 +0000650- Patch #1359618: Speed up charmap encoder by using a trie structure
651 for lookup.
652
Tim Petersd609b1a2006-06-02 23:22:51 +0000653- The functions in the ``pprint`` module now sort dictionaries by key
654 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
655 if and only if its display required more than one line, although that
656 wasn't documented. The new behavior increases predictability; e.g.,
657 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
658
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000659- Patch #1497027: try HTTP digest auth before basic auth in urllib2
660 (thanks for J. J. Lee).
661
Georg Brandl2b330372006-05-28 20:23:12 +0000662- Patch #1496206: improve urllib2 handling of passwords with respect to
663 default HTTP and HTTPS ports.
664
George Yoshidaf3c65de2006-05-28 16:39:09 +0000665- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
666
Bob Ippolito7298f272006-05-23 18:43:47 +0000667- Patch #1281707: speed up gzip.readline.
668
Georg Brandlb89316f2006-05-17 15:51:16 +0000669- Patch #1180296: Two new functions were added to the locale module:
670 format_string() to get the effect of "format % items" but locale-aware,
671 and currency() to format a monetary number with currency sign.
672
Georg Brandle3a25832006-05-17 14:56:04 +0000673- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
674 and several features added, such as speed and geometry control.
675
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000676- Patch #1488881: add support for external file objects in bz2 compressed
677 tarfiles.
678
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000679- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
680 stdout arguments, making it possible to redirect input and output
681 for remote debugging.
682
683- Patch #1484695: Update the tarfile module to version 0.8. This fixes
684 a couple of issues, notably handling of long file names using the
685 GNU LONGNAME extension.
686
687- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
688 new flag when ``name`` is already the name of an option flag.
689
690- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
691 package.
692
693- Patch #1472854: make the rlcompleter.Completer class usable on non-
694 UNIX platforms.
695
696- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
697
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000698- Bug #1472827: correctly escape newlines and tabs in attribute values in
699 the saxutils.XMLGenerator class.

728
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000729What's New in Python 2.5 alpha 2?
730=================================
731
732*Release date: 27-APR-2006*
733
734Core and builtins
735-----------------
736
Thomas Heller1b046642006-04-18 18:51:06 +0000737- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
738 by converting these apis from macros into exported functions again:
739
740 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
741 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
742 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
743 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
744 PyRun_String Py_CompileString
745
Martin v. Löwis45294a92006-04-18 06:24:08 +0000746- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
747
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000748- All uses of PyStructSequence_InitType have been changed to initialize
749 the type objects only once, even if the interpreter is initialized
750 multiple times.
751
Neal Norwitz61546162006-04-14 05:20:28 +0000752- Bug #1454485, array.array('u') could crash the interpreter. This was
753 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
754 to unicode when it didn't make sense. 'u#' now requires a unicode string.
755
756- Py_UNICODE is unsigned. It was always documented as unsigned, but
757 due to a bug had a signed value in previous versions.
758
Tim Peters3a5e8b12006-04-11 01:44:07 +0000759- Patch #837242: ``id()`` of any Python object always gives a positive
760 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
761 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000762 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000763 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000764
Tim Peters3a5e8b12006-04-11 01:44:07 +0000765 def __hash__(self):
766 return id(self) # WRONG
767
768 because a hash result must be a (short) Python int but it was always
769 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000770 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000771 was always usable as a hash value before this patch. That's no longer
772 necessarily so.
773
774- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000775 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000776 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000777 #1454844)
778
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000779- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
780 involving generators that have paused outside of any ``try`` or ``with``
781 blocks. (In 2.5a1, a paused generator that was part of a reference
782 cycle could not be garbage collected, regardless of whether it was
783 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000785Extension Modules

789 is a macro.
790
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000791- Bug #1467952: os.listdir() now correctly raises an error if readdir()
792 fails with an error condition.
793
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000794- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
795
796- Bug #1117761: bsddb.*open() no longer raises an exception when using
797 the cachesize parameter.
798
799- Bug #1149413: bsddb.*open() no longer raises an exception when using
800 a temporary db (file=None) with the 'n' flag to truncate on open.
801
802- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
803 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000804
Armin Rigoa9017c32006-04-19 11:50:27 +0000805- Patch #1062014: AF_UNIX sockets under Linux have a special
806 abstract namespace that is now fully supported.
807
Anthony Baxter51bcb682006-04-05 14:51:42 +0000808Library
809-------
810
Peter Astrand7d1d4362006-07-14 14:04:45 +0000811- Bug #1223937: subprocess.CalledProcessError reports the exit status
812 of the process using the returncode attribute, instead of
813 abusing errno.
814
Tim Peters711bf302006-04-25 03:31:36 +0000815- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
816 a doctest to be skipped (the code is not run, and the expected output
817 or exception is ignored).
818
Nick Coghlanda2268f2006-04-24 04:37:15 +0000819- Fixed contextlib.nested to cope with exceptions being raised and
820 caught inside exit handlers.
821
Greg Wardab05edc2006-04-23 03:47:58 +0000822- Updated optparse module to Optik 1.5.1 (allow numeric constants in
823 hex, octal, or binary; add ``append_const`` action; keep going if
824 gettext cannot be imported; added ``OptionParser.destroy()`` method;
825 added ``epilog`` for better help generation).
826
Tim Peters21fbd572006-04-21 21:18:10 +0000827- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
828 called from a thread spawned as a side effect of importing a module.
829
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000830- The pydoc module now supports documenting packages contained in
831 .zip or .egg files.
832
833- The pkgutil module now has several new utility functions, such
834 as ``walk_packages()`` to support working with packages that are either
835 in the filesystem or zip files.
836
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000837- The mailbox module can now modify and delete messages from
838 mailboxes, in addition to simply reading them. Thanks to Gregory
839 K. Johnson for writing the code, and to the 2005 Google Summer of
840 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000841
Tim Petersc7605f22006-04-17 21:12:33 +0000842- The ``__del__`` method of class ``local`` in module ``_threading_local``
843 returned before accomplishing any of its intended cleanup.
844
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000845- Patch #790710: Add breakpoint command lists in pdb.
846
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000847- Patch #1063914: Add Tkinter.Misc.clipboard_get().

850
Anthony Baxtere29002c2006-04-12 12:07:31 +0000851- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
852 Windows. Bug #1469163.
853
Phillip J. Eby47032112006-04-11 01:07:43 +0000854- The warnings, linecache, inspect, traceback, site, and doctest modules
855 were updated to work correctly with modules imported from zipfiles or
856 via other PEP 302 __loader__ objects.
857
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000858- Patch #1467770: Reduce usage of subprocess._active to processes which
859 the application hasn't waited on.
860

Skip Montanaro262fb922006-04-21 02:31:07 +0000865- The pstats.Stats class accepts an optional stream keyword argument to
866 direct output to an alternate file-like object.
867

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000878- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
879 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000880 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000881 CXX from --with-cxx-main, see description in README.
882
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000883- Patch #1429775: Link extension modules with the shared libpython.
884

886
Tim Peters8931ff12006-05-13 23:28:20 +0000887- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
888 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
889 and "%zu" for unsigned integers of type ``size_t``.
890
Anthony Baxter51bcb682006-04-05 14:51:42 +0000891Tests
892-----
893
Nick Coghlanda2268f2006-04-24 04:37:15 +0000894- test_contextlib now checks contextlib.nested can cope with exceptions
895 being raised and caught inside exit handlers.
896
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000897- test_cmd_line now checks operation of the -m and -c command switches
898
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000899- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
900 it separately and by hand. It also wasn't cleaning up its changes to
901 the current Decimal context.
902
Thomas Woutersabd08882006-04-26 15:53:30 +0000903- regrtest.py now has a -M option to run tests that test the new limits of
904 containers, on 64-bit architectures. Running these tests is only sensible
905 on 64-bit machines with more than two gigabytes of memory. The argument
906 passed is the maximum amount of memory for the tests to use.

915-------------
916
Tim Petersb06d28c2006-05-12 01:57:59 +0000917- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
918
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000919- PEP 343: Added Context Types section to the library reference
920 and attempted to bring other PEP 343 related documentation into
921 line with the implementation and/or python-dev discussions.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000927What's New in Python 2.5 alpha 1?
928=================================
929
Anthony Baxterebed3f62006-04-03 15:03:44 +0000930*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000931

933-----------------
934
Nick Coghlan43832302006-04-23 17:04:07 +0000935- PEP 338: -m command line switch now delegates to runpy.run_module
936 allowing it to support modules in packages and zipfiles
937
Martin v. Löwisc661b882006-04-20 04:54:23 +0000938- On Windows, .DLL is not an accepted file name extension for
939 extension modules anymore; extensions are only found if they
940 end in .PYD.
941
Martin v. Löwisea62d252006-04-03 10:56:49 +0000942- Bug #1421664: sys.stderr.encoding is now set to the same value as
943 sys.stdout.encoding.
944
Neal Norwitz92e212f2006-04-03 04:48:37 +0000945- __import__ accepts keyword arguments.

Hye-Shik Changd478f342006-03-23 12:32:36 +0000951- Patch #1396919: The system scope threads are reenabled on FreeBSD
952 5.4 and later versions.
953
Neal Norwitze98ccf62006-03-23 05:39:47 +0000954- Bug #1115379: Compiling a Unicode string with an encoding declaration
955 now gives a SyntaxError.
956
Georg Brandlabd1ff82006-03-18 07:59:59 +0000957- Previously, Python code had no easy way to access the contents of a
958 cell object. Now, a ``cell_contents`` attribute has been added
959 (closes patch #1170323).
960
Tim Peterscf79aac2006-03-16 01:14:46 +0000961- Patch #1123430: Python's small-object allocator now returns an arena to
962 the system ``free()`` when all memory within an arena becomes unused
963 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
964 freed. Some applications will see a drop in virtual memory size now,
965 especially long-running applications that, from time to time, temporarily
966 use a large number of small objects. Note that when Python returns an
967 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000968 platform C library will in turn return that memory to the operating system.
969 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000970 appears to be effective at least on Microsoft C and gcc-based systems.
971 Thanks to Evan Jones for hard work and patience.
972
Georg Brandl533ff6f2006-03-08 18:09:27 +0000973- Patch #1434038: property() now uses the getter's docstring if there is
974 no "doc" argument given. This makes it possible to legitimately use
975 property() as a decorator to produce a read-only property.
976
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000977- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
978 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
979 of requiring an int or long in slicing and a few other contexts, enabling
980 other objects (e.g. Numeric Python's integers) to be used as slice indices.
981
Neal Norwitz995acdf2006-03-07 05:01:00 +0000982- Fixed various bugs reported by Coverity's Prevent tool.
983
Brett Cannonbf364092006-03-01 04:25:17 +0000984- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
985 new exception base class, BaseException, which has a new message attribute.
986 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
987 Raising a string exception now raises a DeprecationWarning.
988
Thomas Woutersfb609f42006-02-28 16:37:25 +0000989- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
990 explicitly relative, using 'from .module import name' to mean 'from the same
991 package as this module is in. Imports without dots still default to the
992 old relative-then-absolute, unless 'from __future__ import
993 absolute_import' is used.
994
Brett Cannona7446e32006-02-27 23:39:10 +0000995- Properly check if 'warnings' raises an exception (usually when a filter set
996 to "error" is triggered) when raising a warning for raising string
997 exceptions.
998
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000999- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001000 The name was removed from Include/code.h.
1001
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001002- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001003
Guido van Rossum1968ad32006-02-25 22:38:04 +00001004- Patch 1433928:
1005 - The copy module now "copies" function objects (as atomic objects).
1006 - dict.__getitem__ now looks for a __missing__ hook before raising
1007 KeyError.
1008
Tim Peters84ef21c2006-02-28 20:39:06 +00001009- PEP 343: with statement implemented. Needs ``from __future__ import
1010 with_statement``. Use of 'with' as a variable will generate a warning.
1011 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001012 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001013 The following objects have __context__ methods:
1014 - The built-in file type.
1015 - The thread.LockType type.
1016 - The following types defined by the threading module:
1017 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1018 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001019
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001020- Fix the encodings package codec search function to only search
1021 inside its own package. Fixes problem reported in patch #1433198.
1022
1023 Note: Codec packages should implement and register their own
1024 codec search function. PEP 100 has the details.
1025
Tim Peters9ea89d22006-06-04 03:26:02 +00001026- PEP 353: Using ``Py_ssize_t`` as the index type.
1027
1028- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1029 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1030 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1031 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1032 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001033
Neal Norwitzfc76d632006-01-10 06:03:13 +00001034- Patch #1400181, fix unicode string formatting to not use the locale.
1035 This is how string objects work. u'%f' could use , instead of .
1036 for the decimal point. Now both strings and unicode always use periods.
1037
Neal Norwitz671b9e32006-01-09 07:07:12 +00001038- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1039 configure would break checking curses.h.
1040
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001041- Bug #959576: The pwd module is now builtin. This allows Python to be
1042 built on UNIX platforms without $HOME set.
1043
Neal Norwitzc10978f2005-12-19 06:07:16 +00001044- Bug #1072182, fix some potential problems if characters are signed.
1045
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001046- Bug #889500, fix line number on SyntaxWarning for global declarations.
1047
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001048- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1049
Neal Norwitze7214a12005-12-18 05:03:17 +00001050- Support for converting hex strings to floats no longer works.
1051 This was not portable. float('0x3') now raises a ValueError.
1052
Barry Warsaw2a38a862005-12-18 01:27:35 +00001053- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001054 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001055 is now displayed in interactive prompt banner.
1056
Georg Brandlfa166682005-12-17 21:45:17 +00001057- Implementation of PEP 341 - Unification of try/except and try/finally.
1058 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001059 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001060
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001061- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1062 now encodes backslash correctly.
1063
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001064- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1065
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001066- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001067 and long longs.
1068
Neal Norwitz67715f02005-11-09 06:59:35 +00001069- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001070 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001071 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001072
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001073- Replaced most Unicode charmap codecs with new ones using the
1074 new Unicode translate string feature in the builtin charmap
1075 codec; the codecs were created from the mapping tables available
1076 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1077 encodings now include a mapping for the Apple logo)
1078
Tim Peterse3547fd2005-12-16 23:13:57 +00001079- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001080
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001081- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001082
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001083- A new AST parser implementation was completed. The abstract
1084 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001085 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001086
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001087- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001088 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1089
Neal Norwitz708e51a2005-10-03 04:48:15 +00001090- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1091
Neal Norwitz11bd1192005-10-03 00:54:56 +00001092- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1093 Provide a warning when a directory is passed on the command line.
1094
Neal Norwitz40d37812005-10-02 01:48:49 +00001095- Fix segfault with invalid coding.
1096
1097- SF bug #772896: unknown encoding results in MemoryError.
1098
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001099- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001100 supported a __len__() method which evaluated to False when the iterator
1101 was empty.
1102
Guido van Rossum630db602005-09-20 18:49:54 +00001103- On 64-bit platforms, when __len__() returns a value that cannot be
1104 represented as a C int, raise OverflowError.
1105
Skip Montanarof8948ca2005-09-19 03:54:46 +00001106- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001107 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001108
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001109- SF bug #893549: parsing keyword arguments was broken with a few format
1110 codes.
1111
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001112- Changes donated by Elemental Security to make it work on AIX 5.3
1113 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1114 bug #105470: test_pwd fails on 64bit system (Opteron).
1115
Guido van Rossum539c6622005-09-14 17:49:54 +00001116- Changes donated by Elemental Security to make it work on HP-UX 11 on
1117 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1118
Georg Brandl4550b8d2005-08-26 06:43:52 +00001119- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001120 (fixes bug #1119418).
1121
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001122- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1123
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001124- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1125 exceptions that cause a function to exit.
1126
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001127- The implementation of set() and frozenset() was revised to use its
1128 own internal data structure. Memory consumption is reduced by 1/3
1129 and there are modest speed-ups as well. The API is unchanged.
1130
Tim Petersde7990b2005-07-17 23:45:23 +00001131- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1132
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001133- SF bug #1229429: PyObject_CallMethod failed to decrement some
1134 reference counts in some error exit cases.
1135
Tim Petersecc6e6a2005-07-10 22:30:55 +00001136- SF bug #1185883: Python's small-object memory allocator took over
1137 a block managed by the platform C library whenever a realloc specified
1138 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001139 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001140 portable way to copy data from the C-managed block into Python's
1141 small-object space without risking a memory fault. Python's small-object
1142 realloc now leaves such blocks under the control of the platform C
1143 realloc.
1144
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001145- SF bug #1232517: An overflow error was not detected properly when
1146 attempting to convert a large float to an int in os.utime().
1147
Raymond Hettinger3296e692005-06-29 23:29:56 +00001148- SF bug #1224347: hex longs now print with lowercase letters just
1149 like their int counterparts.
1150
Michael W. Hudson188d4362005-06-20 16:52:57 +00001151- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1152 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1153 interpreter states; back out that fix and do a better job (see
1154 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1155 for a longer write-up of the problem).
1156
Michael W. Hudsondf888462005-06-03 14:41:55 +00001157- SF patch #1180995: marshal now uses a binary format by default when
1158 serializing floats.
1159
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001160- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1161 the routines that promise to produce IEEE 754 binary representations
1162 of floats now simply copy bytes around.
1163
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001164- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1165 278.
1166
Brett Cannonc3647ac2005-04-26 03:45:26 +00001167- patch #1109424: int, long, float, complex, and unicode now check for the
1168 proper magic slot for type conversions when subclassed. Previously the
1169 magic slot was ignored during conversion. Semantics now match the way
1170 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001171 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001172 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001173 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001174
Barry Warsawc8d907c2005-04-19 23:43:40 +00001175- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1176 NULL, now raise an AttributeError when attempting to set or delete the
1177 attribute. Previously a TypeError was raised, but this was inconsistent
1178 with the equivalent pure-Python implementation.
1179
Michael W. Hudson774479c2005-04-18 08:46:17 +00001180- It is now safe to call PyGILState_Release() before
1181 PyEval_InitThreads() (note that if there is reason to believe there
1182 are multiple threads around you still must call PyEval_InitThreads()
1183 before using the Python API; this fix is for extension modules that
1184 have no way of knowing if Python is multi-threaded yet).
1185
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001186- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1187 disabled caused a crash.
1188
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001189- Bug #1165306: instancemethod_new allowed the creation of a method
1190 with im_class == im_self == NULL, which caused a crash when called.
1191
Tim Petersecc6e6a2005-07-10 22:30:55 +00001192- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001193 fixes the crash seen in bug #1165761
1194
Raymond Hettinger96229b12005-03-11 06:49:40 +00001195- Added two new builtins, any() and all().
1196
Brett Cannon409d8f22005-03-05 06:47:57 +00001197- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001198 (e.g., ``class C(): pass`` is no longer a syntax error).
1199 Patch #1176012 added support to the 'parser' module and 'compiler' package
1200 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001201
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001202- Patch #1115086: Support PY_LONGLONG in structmember.
1203
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001204- Bug #1155938: new style classes did not check that __init__() was
1205 returning None.
1206
Tim Petersecc6e6a2005-07-10 22:30:55 +00001207- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001208 ('\') with a specific error message.
1209
Martin v. Löwisff232d72005-03-03 09:24:38 +00001210- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1211
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001212- Bug #1124295: the __name__ attribute of file objects was

1234 unicode instance if the argument is not an instance of basestring and
1235 calling __str__ on the argument returns a unicode instance.
1236
Tim Petersf4e69282006-02-27 17:15:31 +00001237- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1238 current thread state when the auto-GIL-state machinery knows about
1239 it (since the thread state is being deleted, continuing to remember it
1240 can't help, but can hurt if another thread happens to get created with
1241 the same thread id).

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001436
Nick Coghlan43832302006-04-23 17:04:07 +00001437- PEP 338: new module runpy defines a run_module function to support
1438 executing modules which provide access to source code or a code object
1439 via the PEP 302 import mechanisms.
1440

1449 in attribute values.
1450
Anthony Baxterc51ee692006-04-01 00:57:31 +00001451- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001452 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001453 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001454 module will not be built.
1455
Tim Petersc17976e2006-04-01 00:26:53 +00001456- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1457 aren't officially supported here, and trying to use them will probably
1458 raise an exception some day. But dicts have been allowed, and "mostly
1459 worked", so support for them won't go away without warning.

Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001480- email 4.0 package now integrated. This is largely the same as the email 3.0
1481 package that was included in Python 2.3, except that PEP 8 module names are
1482 now used (e.g. mail.message instead of email.Message). The MIME classes
1483 have been moved to a subpackage (e.g. email.mime.text instead of
1484 email.MIMEText). The old names are still supported for now. Several
1485 deprecated Message methods have been removed and lots of bugs have been
1486 fixed. More details can be found in the email package documentation.

1489 (a subclass of tuple) that provides incremental decoders and encoders
1490 (a way to use stateful codecs without the stream API). Python functions
1491 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1492 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1493 have been added.

1574 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1575 Ronald L. Rivest offered this advice for Python:
1576
1577 "The consensus of researchers in this area (at least as
1578 expressed at the NIST Hash Function Workshop 10/31/05),
1579 is that SHA-256 is a good choice for the time being, but
1580 that research should continue, and other alternatives may
1581 arise from this research. The larger SHA's also seem OK."

Guido van Rossumd0641422005-02-03 15:01:24 +00001742- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1743 disables recursive traversal through instance attributes, which can
1744 be exploited in various ways.
1745
Tim Peterse3547fd2005-12-16 23:13:57 +00001746- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001747 flags on the HTTP listening socket.
1748
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001749- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1750 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1751
Fred Drakefbdeaad2006-07-29 16:56:15 +00001752- Patches #893642, #1039083: add allow_none, encoding arguments to
1753 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001754
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001755- Bug #1110478: Revert os.environ.update to do putenv again.
1756
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001757- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1758
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001759- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1760
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001761- Enhancements to the csv module:
1762
1763 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001764 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001765 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001766 + Dialect parameter parsing has been re-implemented to improve error
1767 reporting.
1768 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1769 dictates.
1770 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001771 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001772 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001773 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1774 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001775 + reader now allows \r characters to be quoted (previously it only allowed
1776 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001777 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001778 + Dialect classes passed to the module are no longer instantiated by
1779 the module before being parsed (the former validation scheme required
1780 this, but the mechanism was unreliable).
1781 + The dialect registry now contains instances of the internal
1782 C-coded dialect type, rather than references to python objects.
1783 + the internal c-coded dialect type is now immutable.
1784 + register_dialect now accepts the same keyword dialect specifications
1785 as the reader and writer, allowing the user to register dialects
1786 without first creating a dialect class.
1787 + a configurable limit to the size of parsed fields has been added -
1788 previously, an unmatched quote character could result in the entire
1789 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001790 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001791 the parser field size limit (returning the former limit). The initial
1792 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001793 + A line_num attribute has been added to the reader object, which tracks
1794 the number of lines read from the source iterator. This is not
1795 the same as the number of records returned, as records can span
1796 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001797 + reader and writer objects were not being registered with the cyclic-GC.
1798 This has been fixed.
1799
Brett Cannone6539c42005-01-08 02:43:53 +00001800- _DummyThread objects in the threading module now delete self.__block that is
1801 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1802 lock primitives tend to be limited in number and thus should not be wasted on
1803 a _DummyThread object. Fixes bug #1089632.
1804
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001805- The imghdr module now detects Exif files.
1806
Raymond Hettinger6065d322004-12-20 23:51:53 +00001807- StringIO.truncate() now correctly adjusts the size attribute.
1808 (Bug #951915).
1809
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001810- locale.py now uses an updated locale alias table (built using
1811 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1812 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001813 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001814
Raymond Hettinger3557f422004-12-07 12:02:02 +00001815- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1816
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001817- the pickle module no longer accepts the deprecated None option in the
1818 args tuple returned by __reduce__().
1819
Brett Cannon84667c02004-12-07 03:25:18 +00001820- optparse now optionally imports gettext. This allows its use in setup.py.
1821
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001822- the pickle module no longer uses the deprecated bin parameter.
1823
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001824- the shelve module no longer uses the deprecated binary parameter.
1825
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001826- the pstats module no longer uses the deprecated ignore() method.
1827
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001828- the filecmp module no longer uses the deprecated use_statcache argument.
1829
Raymond Hettinger664347b2004-12-04 21:21:53 +00001830- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1831 extended or overridden by subclasses. Formerly, the subclassed method would
1832 be ignored by the rest of the module. (Bug #1078905).
1833
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001834- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001835 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001836
Walter Dörwald36733692004-12-22 12:50:50 +00001837- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1838 once when a size argument is given. This prevents a buffer overflow in the
1839 tokenizer with very long source lines.
1840
Barry Warsaw538561e2006-01-01 21:48:54 +00001841- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1842 immediately after creating the object, without any intervening
1843 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001844
Skip Montanaro05885812005-01-16 20:48:27 +00001845- The reconvert.quote function can now emit triple-quoted strings. The
1846 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001847
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001848- ``UserString.MutableString`` now supports negative indices in
1849 ``__setitem__`` and ``__delitem__``
1850
Greg Ward40407942005-03-05 02:53:17 +00001851- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1852 correctly.
1853
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001854- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1855 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1856 character even if the user has passed a size parameter to get a proper
1857 line ending. Remove the special handling of a "\r\n" that has been split
1858 between two lines.
1859
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001860- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1861 about illegal code points. The codec now supports PEP 293 style error
1862 handlers.
1863
Walter Dörwald78a78b02005-09-01 12:04:29 +00001864- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001865 from the input stream, so that the output is a byte string in the correct
1866 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001867
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001868- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1869 considering it exactly like a '*'.
1870
Walter Dörwald007f8df2005-10-09 19:42:27 +00001871- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1872 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001873
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001874- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1875
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001876- Patch #1413711: Certain patterns of differences were making difflib
1877 touch the recursion limit.
1878
Walter Dörwald58917a62006-03-31 15:26:22 +00001879- Bug #947906: An object oriented interface has been added to the calendar
1880 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001881 called as a script (e.g. via ``python -mcalendar``). Localized month and
1882 weekday names can be ouput (even if an exotic encoding is used) using
1883 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001884
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001885Build
1886-----
1887
Neal Norwitz602d3392006-03-31 08:21:40 +00001888- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1889 by using -mieee gcc option.
1890

1892
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001893- Build support for Win64-AMD64 was added.
1894
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001895- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1896
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001897- Patch #881820: look for openpty and forkpty also in libbsd.
1898
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001899- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1900 The zlib module is now builtin on Windows.
1901
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001902- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1903
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001904- Bug #1189330: configure did not correctly determine the necessary
1905 value of LINKCC if python was built with GCC 4.0.
1906
Trent Mick8321b422005-07-26 02:29:21 +00001907- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1908 vulnerability in zlib 1.2.1 and 1.2.2.
1909
Brett Cannon08cd5982005-04-24 22:26:38 +00001910- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1911 flags that change binary compatibility. Changes were also made to
1912 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001913 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001914
Bob Ippolitoed233462005-03-29 13:47:59 +00001915- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1916 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1917 no longer exists). This configure patch makes things right.
1918
Martin v. Löwise2713be2005-03-08 15:03:08 +00001919- Bug #1158607: Build with --disable-unicode again.
1920
Brett Cannon46d96232005-02-16 00:07:19 +00001921- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1922 defined. Discovered as a result of not being able to build on OS X.
1923
Brett Cannon516592f2004-12-07 00:42:59 +00001924- setup.py now uses the directories specified in LDFLAGS using the -L option
1925 and in CPPFLAGS using the -I option for adding library and include
1926 directories, respectively, for compiling extension modules against. This has
1927 led to the core being compiled using the values in CPPFLAGS. It also removes
1928 the need for the special-casing of both DarwinPorts and Fink for darwin since
1929 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1930 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1931 Fink, ``-I/opt/local/include`` for DarwinPorts).
1932
Brett Cannon43802422005-02-10 20:48:03 +00001933- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1934 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1935 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1936 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001938C API
1939-----
1940
Tim Petersc9d78aa2006-03-26 23:27:58 +00001941- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1942 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1943 is obtained via the ``PyObject_`` family, it must be released via the
1944 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1945 always been officially true, but when Python's small-object allocator was
1946 introduced, an attempt was made to cater to a few extension modules
1947 discovered at the time that obtained memory via ``PyObject_New`` but
1948 released it via ``PyMem_DEL``. It's years later, and if such code still
1949 exists it will fail now (probably with segfaults, but calling wrong
1950 low-level memory management functions can yield many symptoms).
1951
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001952- Added a C API for set and frozenset objects.
1953

1955
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001956- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1957 mapping argument now. This string is used as a mapping table. Byte values
1958 greater than the length of the string and 0xFFFE are treated as undefined
1959 mappings.
