8=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +00009
Guido van Rossum133f4e42006-08-10 17:42:50 +000010*Release date: 18-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +000011
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().

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

Fred Drake53912162006-07-29 13:22:49 +000096What's New in Python 2.5 beta 3?
97================================
Neal Norwitza1f10902006-07-12 07:28:29 +000098
Anthony Baxter5d32a9f2006-08-02 07:43:09 +000099*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000100
101Core and builtins
102-----------------
103
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000104- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t, it previously
105 returned a long (see PEP 353).
106
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000107- Bug #1515471: string.replace() accepts character buffers again.
108
Neal Norwitz07aadb12006-07-30 06:55:48 +0000109- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
110 This provides the proper warning for struct.pack().
111 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
112
Neal Norwitz0d62a062006-07-30 06:53:31 +0000113- Patch #1531113: Fix augmented assignment with yield expressions.
114 Also fix a SystemError when trying to assign to yield expressions.
115
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000116- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
117 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
118 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
119 excessive filesystem operations during imports.
120
Tim Petersbc24eee2006-07-27 01:14:53 +0000121- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
122 operations on signed longs that are formally undefined by C.
123 Unfortunately, at least one compiler now cares about that, so complicated
124 the code to make that compiler happy again.
125
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000126- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
127
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000128- Patch #1232023: Stop including current directory in search
129 path on Windows.
130
Neal Norwitze1fdb322006-07-21 05:32:28 +0000131- Fix some potential crashes found with failmalloc.
132
Neal Norwitze7563102006-07-17 01:00:16 +0000133- Fix warnings reported by Klocwork's static analysis tool.
134
Neal Norwitz84be93b2006-07-16 01:50:38 +0000135- Bug #1512814, Fix incorrect lineno's when code within a function
136 had more than 255 blank lines.
137
Georg Brandl9dceedb2006-07-12 15:31:17 +0000138- Patch #1521179: Python now accepts the standard options ``--help`` and
139 ``--version`` as well as ``/?`` on Windows.
140
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000141- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000142 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000143 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000144
Tim Peters112aad32006-07-19 00:03:19 +0000145- Bug #1524317: Compiling Python ``--without-threads`` failed.
146 The Python core compiles again then, and, in a build without threads, the
147 new ``sys._current_frames()`` returns a dictionary with one entry,
148 mapping the faux "thread id" 0 to the current frame.
149
Ronald Oussoren3075e162006-07-25 20:28:55 +0000150- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000151
Ronald Oussoren3075e162006-07-25 20:28:55 +0000152
Neal Norwitza1f10902006-07-12 07:28:29 +0000153Library
154-------
155
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000156- Correction of patch #1455898: In the mbcs decoder, set final=False
157 for stream decoder, but final=True for the decode function.
158
Georg Brandl07fec3a2006-08-01 18:49:24 +0000159- os.urandom no longer masks unrelated exceptions like SystemExit or
160 KeyboardInterrupt.
161
Tim Peters4643c2f2006-08-10 22:45:34 +0000162- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000163 shutil.copytree on Windows
164
Georg Brandle34ac7c2006-07-30 11:07:23 +0000165- Bug #1002398: The documentation for os.path.sameopenfile now correctly
166 refers to file descriptors, not file objects.
167
Fred Drakefbdeaad2006-07-29 16:56:15 +0000168- Rename of the xml package to xmlcore, and the import hackery done to
169 make it appear at both names, has been removed. Bug #1511497,
170 #1513611, and probably others.
171
Georg Brandledd9b0d2006-07-29 09:33:26 +0000172- Bug #1441397: The compiler module now recognizes module and function
173 docstrings correctly as it did in Python 2.4.
174
Tim Peters6f681472006-07-27 23:44:37 +0000175- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
176 lost that tests are sorted by name before being run. This rarely
177 matters for well-written tests, but can create baffling symptoms if
178 side effects from one test to the next affect outcomes. ``DocTestFinder``
179 has been changed to sort the list of tests it returns.
180
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000181- The distutils version has been changed to 2.5.0, and are now kept
182 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000183
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000184- Bug #978833: Really close underlying socket in _socketobject.close.
185
Georg Brandl0619a322006-07-26 07:40:17 +0000186- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
187 with title().
188
Georg Brandlcf0c1722006-07-26 07:23:32 +0000189- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
190 to recursive calls and call it with the failing package name.
191
Martin v. Löwis0b483032006-07-25 09:53:12 +0000192- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
193
Georg Brandlc13c34c2006-07-24 14:09:56 +0000194- Patch #1515343: Fix printing of deprecated string exceptions with a
195 value in the traceback module.
196
Greg Ward48fae7a2006-07-23 16:05:51 +0000197- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
198
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000199- Patch #1524429: Use repr() instead of backticks in Tkinter again.
200
Brett Cannoncaebe222006-07-18 04:41:36 +0000201- Bug #1520914: Change time.strftime() to accept a zero for any position in its
202 argument tuple. For arguments where zero is illegal, the value is forced to
203 the minimum value that is correct. This is to support an undocumented but
204 common way people used to fill in inconsequential information in the time
205 tuple pre-2.4.
206
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000207- Patch #1220874: Update the binhex module for Mach-O.
208
Barry Warsawb110bad2006-07-21 14:51:07 +0000209- The email package has improved RFC 2231 support, specifically for
210 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
211 (name*0=<blah>) parameter continuations. This may change the types of
212 values returned from email.message.Message.get_param() and friends.
213 Specifically in some cases where non-encoded continuations were used,
214 get_param() used to return a 3-tuple of (None, None, string) whereas now it
215 will just return the string (since non-encoded continuations don't have
216 charset and language parts).
217
218 Also, whereas % values were decoded in all parameter continuations, they are
219 now only decoded in encoded parameter parts.
220
Ronald Oussoren3075e162006-07-25 20:28:55 +0000221- Bug #1517990: IDLE keybindings on MacOS X now work correctly
222
223- Bug #1517996: IDLE now longer shows the default Tk menu when a
224 path browser, class browser or debugger is the frontmost window on MacOS X
225
Barry Warsaw00decd72006-07-27 23:43:15 +0000226- Patch #1520294: Support for getset and member descriptors in types.py,
227 inspect.py, and pydoc.py. Specifically, this allows for querying the type
228 of an object against these built-in types and more importantly, for getting
229 their docstrings printed in the interactive interpreter's help() function.

234
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000235- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
236 a socket operation on a socket with a timeout, the exception will be
237 caught correctly. Previously, the exception was not caught.
238
Thomas Heller1393d6a2006-07-28 21:43:20 +0000239- Patch #1529514: The _ctypes extension is now compiled on more
240 openbsd target platforms.
241
Tim Peters9cab5932006-07-28 00:30:00 +0000242- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
243 a memory leak, affecting pickles and deep copies.
244
Tim Petersbc24eee2006-07-27 01:14:53 +0000245- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

247
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000248- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
249
Thomas Hellerce049a02006-07-14 17:51:14 +0000250- Patch #1521817: Index range checking on ctypes arrays containing
251 exactly one element enabled again. This allows iterating over these
252 arrays, without the need to check the array size before.
253
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000254- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000255 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000256 /dev/null in certain cases; this is now fixed.
257
Thomas Heller47d7a062006-07-12 08:43:47 +0000258- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
259 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000260
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000261- Because of a misspelled preprocessor symbol, ctypes was always
262 compiled without thread support; this is now fixed.
263
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000264- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
265 methods now allow their database parameter to be None as the
266 sleepycat API allows.
267
Matt Flemingec926502006-07-28 11:27:27 +0000268- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
269 bluetooth API compared with Linux and FreeBSD.
270

272-----
273
274- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
275 how long the test file should take to play. Now accepts taking 2.93 secs
276 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
277
Georg Brandl4793aa32006-07-28 18:31:39 +0000278- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
279 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
280 run via ``regrtest.py``. Now they do.

289
290- PythonLauncher now works correctly when the path to the script contains
291 characters that are treated specially by the shell (such as quotes).
292
293- Bug #1527397: PythonLauncher now launches scripts with the working directory
294 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000295 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000296 expect.

Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000319- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
320 omit a default "error" argument for NULL pointer. This allows
321 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000322
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000323- Bug #1519018: 'as' is now validated properly in import statements.
324
Neal Norwitz28746ab2006-07-09 22:14:42 +0000325- On 64 bit systems, int literals that use less than 64 bits are
326 now ints rather than longs.
327
Neal Norwitzed657552006-07-10 00:04:44 +0000328- Bug #1512814, Fix incorrect lineno's when code at module scope
329 started after line 256.
330
Tim Peters32a83612006-07-10 21:08:24 +0000331- New function ``sys._current_frames()`` returns a dict mapping thread
332 id to topmost thread stack frame. This is for expert use, and is
333 especially useful for debugging application deadlocks. The functionality
334 was previously available in Fazal Majid's ``threadframe`` extension
335 module, but it wasn't possible to do this in a wholly threadsafe way from
336 an extension.

356 be treated as the value they contain, instead.
357
Martin v. Löwisede77f52006-07-03 13:01:35 +0000358- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

383
Brett Cannon53ab5b72006-06-22 16:49:14 +0000384- Bug #1510580: The 'warnings' module improperly required that a Warning
385 category be either a types.ClassType and a subclass of Warning. The proper
386 check is just that it is a subclass with Warning as the documentation states.
387
Georg Brandlad29e632006-06-21 17:45:17 +0000388- The compiler module now correctly compiles the new try-except-finally

401-----------------
402
Tim Peters112aad32006-07-19 00:03:19 +0000403- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
404 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
405 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000406
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000407- Assigning None to pointer type fields in ctypes structures possible
408 overwrote the wrong fields, this is fixed now.
409
410- Fixed a segfault in _ctypes when ctypes.wintypes were imported
411 on non-Windows platforms.
412
413- Bug #1518190: The ctypes.c_void_p constructor now accepts any
414 integer or long, without range checking.
415
416- Patch #1517790: It is now possible to use custom objects in the ctypes
417 foreign function argtypes sequence as long as they provide a from_param
418 method, no longer is it required that the object is a ctypes type.
419
420- The '_ctypes' extension module now works when Python is configured
421 with the --without-threads option.

438
Tim Peters32a83612006-07-10 21:08:24 +0000439- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000440 Previously, the slight difference could cause compilation errors of the
441 'zlib' module on systems with more than one version of zlib.
442
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000443- The MSI compileall step was fixed to also support a TARGETDIR

474Core and builtins
475-----------------
476
Georg Brandla56b9152006-06-19 06:35:54 +0000477- Patch #1507676: Error messages returned by invalid abstract object operations
478 (such as iterating over an integer) have been improved and now include the
479 type of the offending object to help with debugging.
480
Brett Cannonea3912b2006-06-13 21:46:41 +0000481- Bug #992017: A classic class that defined a __coerce__() method that returned
482 its arguments swapped would infinitely recurse and segfault the interpreter.
483
Neal Norwitz909eb122006-06-12 02:13:21 +0000484- Fix the socket tests so they can be run concurrently.
485
Neal Norwitzb9845e72006-06-12 02:11:18 +0000486- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000487 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000488
Brett Cannon22565aa2006-06-09 22:31:23 +0000489- Bug #532646: object.__call__() will continue looking for the __call__
490 attribute on objects until one without one is found. This leads to recursion
491 when you take a class and set its __call__ attribute to an instance of the
492 class. Originally fixed for classic classes, but this fix is for new-style.
493 Removes the infinite_rec_3 crasher.
494
Georg Brandl24250812006-06-09 18:45:48 +0000495- The string and unicode methods startswith() and endswith() now accept
496 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
497
Brett Cannonde3b0522006-06-08 17:00:45 +0000498- Buffer objects, at the C level, never used the char buffer
499 implementation even when the char buffer for the wrapped object was
500 explicitly requested (originally returned the read or write buffer).
501 Now a TypeError is raised if the char buffer is not present but is
502 requested.
503
Georg Brandlddbaa662006-06-04 21:56:52 +0000504- Patch #1346214: Statements like "if 0: suite" are now again optimized
505 away like they were in Python 2.4.
506
Georg Brandlb7c8f542006-05-27 12:30:25 +0000507- Builtin exceptions are now full-blown new-style classes instead of
508 instances pretending to be classes, which speeds up exception handling
509 by about 80% in comparison to 2.5a2.
510
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000511- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
512 Unicode 4.1.
513
Georg Brandlf4ef1162006-05-26 18:03:31 +0000514- Patch #921466: sys.path_importer_cache is now used to cache valid and
515 invalid file paths for the built-in import machinery which leads to
516 fewer open calls on startup.
517
Tim Peters696cf432006-05-24 21:10:40 +0000518- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
519 of-2 bases. The largest speedup is for inputs with about 1000 decimal
520 digits. Conversion from non-power-of-2 bases remains quadratic-time in
521 the number of input digits (it was and remains linear-time for bases
522 2, 4, 8, 16 and 32).
523
Tim Petersb713ec22006-05-23 18:45:30 +0000524- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
525 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
526 an integer close to ``sys.maxint``. This was repaired by patch
527 #1335972, which also gives a nice speedup.
528
Richard Jonescebbefc2006-05-23 18:28:17 +0000529- Patch #1337051: reduced size of frame objects.
530
531- PyErr_NewException now accepts a tuple of base classes as its
532 "base" parameter.
533
Richard Jones7c88dcc2006-05-23 10:37:38 +0000534- Patch #876206: function call speedup by retaining allocated frame
535 objects.
536
Georg Brandl7b90e162006-05-18 07:01:27 +0000537- Bug #1462152: file() now checks more thoroughly for invalid mode
538 strings and removes a possible "U" before passing the mode to the
539 C library function.
540
Neal Norwitz1004a532006-05-15 07:17:23 +0000541- Patch #1488312, Fix memory alignment problem on SPARC in unicode
542
Neal Norwitz373f0a72006-05-15 07:04:36 +0000543- Bug #1487966: Fix SystemError with conditional expression in assignment
544
Martin v. Löwis879768d2006-05-11 13:28:43 +0000545- WindowsError now has two error code attributes: errno, which carries
546 the error values from errno.h, and winerror, which carries the error
547 values from winerror.h. Previous versions put the winerror.h values
548 (from GetLastError()) into the errno attribute.
549
Martin v. Löwis77736712006-05-04 05:51:03 +0000550- Patch #1475845: Raise IndentationError for unexpected indent.
551
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000552- Patch #1479181: split open() and file() from being aliases for each other.
553
Tim Peters44bd9862006-06-01 13:49:23 +0000554- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
555 methods were always silently ignored by dictionaries when comparing keys.
556 They are now passed through (except when using the C API function
557 ``PyDict_GetItem()``, whose semantics did not change).
558
559- Bug #1456209: In some obscure cases it was possible for a class with a
560 custom ``__eq__()`` method to confuse dict internals when class instances
561 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
562 No, you don't have any code that did this ;-)

575
Nick Coghlanc649ec52006-05-29 12:43:05 +0000576- Patch #1478788 (modified version): The functional extension module has
577 been renamed to _functools and a functools Python wrapper module added.
578 This provides a home for additional function related utilities that are
579 not specifically about functional programming. See PEP 309.
580
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000581- Patch #1493701: performance enhancements for struct module.

590
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000591- On Win32, os.listdir now supports arbitrarily-long Unicode path names
592 (up to the system limit of 32K characters).
593
594- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
595 As a result, these functions now raise WindowsError instead of OSError.
596
Tim Peters7a822da2006-05-25 21:50:17 +0000597- ``time.clock()`` on Win64 should use the high-performance Windows
598 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
599 Windows platforms).
600
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000601- Calling Tk_Init twice is refused if the first call failed as that
602 may deadlock.
603
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000604- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
605 accept it without potentially using an uninitialized pointer.
606
607- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
608 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smith506f7b52006-06-15 08:52:32 +0000625- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000626 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000627 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
628 database calls that would previously deadlock. [SF python bug #775414]
629
Vinay Sajip28e57612006-07-01 10:45:20 +0000630- Patch #1446489: add support for the ZIP64 extensions to zipfile.

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000638- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
639 functions.
640
Martin v. Löwis3798da02006-06-17 18:44:27 +0000641- Patch #812986: Update turtle output even if not tracing.
642
Vinay Sajip28e57612006-07-01 10:45:20 +0000643- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000644 Tkinter.BaseWidget.

649 classes.
650
Georg Brandl83cc0d02006-06-14 08:50:03 +0000651- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
652 mime.types file for determining MIME types.
653
Georg Brandl2605ca82006-06-14 06:08:31 +0000654- Bug #1339007: Shelf objects now don't raise an exception in their
655 __del__ method when initialization failed.
656
Martin v. Löwisd8251432006-06-14 05:21:04 +0000657- Patch #1455898: The MBCS codec now supports the incremental mode for
658 double-byte encodings.
659
Tim Peters43898b42006-06-14 04:09:25 +0000660- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
661 guarantee that adjacent triples in the return list always describe
662 non-adjacent blocks. Previously, a pair of matching blocks could end
663 up being described by multiple adjacent triples that formed a partition
664 of the matching pair.
665
Greg Ward0e0c9f42006-06-11 16:24:11 +0000666- Bug #1498146: fix optparse to handle Unicode strings in option help,
667 description, and epilog.
668
Greg Wardd1c797e2006-06-11 14:42:41 +0000669- Bug #1366250: minor optparse documentation error.
670
Greg Ward7f547402006-06-11 00:40:49 +0000671- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
672 clarify docs.
673
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000674- The wsgiref package has been added to the standard library.
675
Nick Coghlan676725d2006-06-08 13:54:49 +0000676- The functions update_wrapper() and wraps() have been added to the functools
677 module. These make it easier to copy relevant metadata from the original
678 function when writing wrapper functions.
679
Tim Petersd6a9eef2006-06-05 01:48:21 +0000680- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
681 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000682
Martin v. Löwis3f767792006-06-04 19:36:28 +0000683- Patch #1359618: Speed up charmap encoder by using a trie structure
684 for lookup.
685
Tim Petersd609b1a2006-06-02 23:22:51 +0000686- The functions in the ``pprint`` module now sort dictionaries by key
687 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
688 if and only if its display required more than one line, although that
689 wasn't documented. The new behavior increases predictability; e.g.,
690 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
691
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000692- Patch #1497027: try HTTP digest auth before basic auth in urllib2
693 (thanks for J. J. Lee).
694
Georg Brandl2b330372006-05-28 20:23:12 +0000695- Patch #1496206: improve urllib2 handling of passwords with respect to
696 default HTTP and HTTPS ports.
697
George Yoshidaf3c65de2006-05-28 16:39:09 +0000698- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
699
Bob Ippolito7298f272006-05-23 18:43:47 +0000700- Patch #1281707: speed up gzip.readline.
701
Georg Brandlb89316f2006-05-17 15:51:16 +0000702- Patch #1180296: Two new functions were added to the locale module:
703 format_string() to get the effect of "format % items" but locale-aware,
704 and currency() to format a monetary number with currency sign.
705
Georg Brandle3a25832006-05-17 14:56:04 +0000706- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
707 and several features added, such as speed and geometry control.
708
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000709- Patch #1488881: add support for external file objects in bz2 compressed
710 tarfiles.
711
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000712- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
713 stdout arguments, making it possible to redirect input and output
714 for remote debugging.
715
716- Patch #1484695: Update the tarfile module to version 0.8. This fixes
717 a couple of issues, notably handling of long file names using the
718 GNU LONGNAME extension.
719
720- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
721 new flag when ``name`` is already the name of an option flag.
722
723- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
724 package.
725
726- Patch #1472854: make the rlcompleter.Completer class usable on non-
727 UNIX platforms.
728
729- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
730
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000731- Bug #1472827: correctly escape newlines and tabs in attribute values in
732 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000762What's New in Python 2.5 alpha 2?
763=================================
764
765*Release date: 27-APR-2006*
766
767Core and builtins
768-----------------
769
Thomas Heller1b046642006-04-18 18:51:06 +0000770- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
771 by converting these apis from macros into exported functions again:
772
773 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
774 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
775 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
776 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
777 PyRun_String Py_CompileString
778
Martin v. Löwis45294a92006-04-18 06:24:08 +0000779- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
780
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000781- All uses of PyStructSequence_InitType have been changed to initialize
782 the type objects only once, even if the interpreter is initialized
783 multiple times.
784
Neal Norwitz61546162006-04-14 05:20:28 +0000785- Bug #1454485, array.array('u') could crash the interpreter. This was
786 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
787 to unicode when it didn't make sense. 'u#' now requires a unicode string.
788
789- Py_UNICODE is unsigned. It was always documented as unsigned, but
790 due to a bug had a signed value in previous versions.
791
Tim Peters3a5e8b12006-04-11 01:44:07 +0000792- Patch #837242: ``id()`` of any Python object always gives a positive
793 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
794 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000795 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000796 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000797
Tim Peters3a5e8b12006-04-11 01:44:07 +0000798 def __hash__(self):
799 return id(self) # WRONG
800
801 because a hash result must be a (short) Python int but it was always
802 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000803 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000804 was always usable as a hash value before this patch. That's no longer
805 necessarily so.
806
807- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000808 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000809 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000810 #1454844)
811
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000812- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
813 involving generators that have paused outside of any ``try`` or ``with``
814 blocks. (In 2.5a1, a paused generator that was part of a reference
815 cycle could not be garbage collected, regardless of whether it was
816 paused in a ``try`` or ``with`` block.)

830 the cachesize parameter.
831
832- Bug #1149413: bsddb.*open() no longer raises an exception when using
833 a temporary db (file=None) with the 'n' flag to truncate on open.
834
835- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
836 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000837
Armin Rigoa9017c32006-04-19 11:50:27 +0000838- Patch #1062014: AF_UNIX sockets under Linux have a special
839 abstract namespace that is now fully supported.

842-------
843
Peter Astrand7d1d4362006-07-14 14:04:45 +0000844- Bug #1223937: subprocess.CalledProcessError reports the exit status
845 of the process using the returncode attribute, instead of
846 abusing errno.
847
Tim Peters711bf302006-04-25 03:31:36 +0000848- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
849 a doctest to be skipped (the code is not run, and the expected output
850 or exception is ignored).
851
Nick Coghlanda2268f2006-04-24 04:37:15 +0000852- Fixed contextlib.nested to cope with exceptions being raised and
853 caught inside exit handlers.
854
Greg Wardab05edc2006-04-23 03:47:58 +0000855- Updated optparse module to Optik 1.5.1 (allow numeric constants in
856 hex, octal, or binary; add ``append_const`` action; keep going if
857 gettext cannot be imported; added ``OptionParser.destroy()`` method;
858 added ``epilog`` for better help generation).
859
Tim Peters21fbd572006-04-21 21:18:10 +0000860- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
861 called from a thread spawned as a side effect of importing a module.
862
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000863- The pydoc module now supports documenting packages contained in
864 .zip or .egg files.
865
866- The pkgutil module now has several new utility functions, such
867 as ``walk_packages()`` to support working with packages that are either
868 in the filesystem or zip files.
869
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000870- The mailbox module can now modify and delete messages from
871 mailboxes, in addition to simply reading them. Thanks to Gregory
872 K. Johnson for writing the code, and to the 2005 Google Summer of
873 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000874
Tim Petersc7605f22006-04-17 21:12:33 +0000875- The ``__del__`` method of class ``local`` in module ``_threading_local``
876 returned before accomplishing any of its intended cleanup.
877

Anthony Baxtere29002c2006-04-12 12:07:31 +0000884- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
885 Windows. Bug #1469163.
886
Phillip J. Eby47032112006-04-11 01:07:43 +0000887- The warnings, linecache, inspect, traceback, site, and doctest modules
888 were updated to work correctly with modules imported from zipfiles or

Martin v. Löwis4be4e652006-04-17 19:25:49 +0000904- The Makefile now has a reindent target, which runs reindent.py on
905 the library.

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000911- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
912 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000913 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000914 CXX from --with-cxx-main, see description in README.
915
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000916- Patch #1429775: Link extension modules with the shared libpython.
917
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000918- Fixed a libffi build problem on MIPS systems.
919
Tim Peters8931ff12006-05-13 23:28:20 +0000920- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
921 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,

925-----
926
Nick Coghlanda2268f2006-04-24 04:37:15 +0000927- test_contextlib now checks contextlib.nested can cope with exceptions
928 being raised and caught inside exit handlers.
929
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000930- test_cmd_line now checks operation of the -m and -c command switches
931
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000932- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
933 it separately and by hand. It also wasn't cleaning up its changes to
934 the current Decimal context.
935
Thomas Woutersabd08882006-04-26 15:53:30 +0000936- regrtest.py now has a -M option to run tests that test the new limits of
937 containers, on 64-bit architectures. Running these tests is only sensible
938 on 64-bit machines with more than two gigabytes of memory. The argument

948-------------
949
Tim Petersb06d28c2006-05-12 01:57:59 +0000950- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
951
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000952- PEP 343: Added Context Types section to the library reference
953 and attempted to bring other PEP 343 related documentation into
954 line with the implementation and/or python-dev discussions.
955
Tim Peters8dc73d22006-04-24 02:03:16 +0000956- Bug #1337990: clarified that ``doctest`` does not support examples
957 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000960What's New in Python 2.5 alpha 1?
961=================================
962
Anthony Baxterebed3f62006-04-03 15:03:44 +0000963*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000964
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000965Core and builtins
966-----------------
967
Nick Coghlan43832302006-04-23 17:04:07 +0000968- PEP 338: -m command line switch now delegates to runpy.run_module
969 allowing it to support modules in packages and zipfiles
970
Martin v. Löwisc661b882006-04-20 04:54:23 +0000971- On Windows, .DLL is not an accepted file name extension for
972 extension modules anymore; extensions are only found if they
973 end in .PYD.
974
Martin v. Löwisea62d252006-04-03 10:56:49 +0000975- Bug #1421664: sys.stderr.encoding is now set to the same value as
976 sys.stdout.encoding.
977
Neal Norwitz92e212f2006-04-03 04:48:37 +0000978- __import__ accepts keyword arguments.
979
Georg Brandlccadf842006-03-31 18:54:53 +0000980- Patch #1460496: round() now accepts keyword arguments.
981
Anthony Baxter262c00a2006-03-30 10:53:17 +0000982- Fixed bug #1459029 - unicode reprs were double-escaped.
983
Hye-Shik Changd478f342006-03-23 12:32:36 +0000984- Patch #1396919: The system scope threads are reenabled on FreeBSD
985 5.4 and later versions.
986
Neal Norwitze98ccf62006-03-23 05:39:47 +0000987- Bug #1115379: Compiling a Unicode string with an encoding declaration
988 now gives a SyntaxError.
989
Georg Brandlabd1ff82006-03-18 07:59:59 +0000990- Previously, Python code had no easy way to access the contents of a
991 cell object. Now, a ``cell_contents`` attribute has been added
992 (closes patch #1170323).
993
Tim Peterscf79aac2006-03-16 01:14:46 +0000994- Patch #1123430: Python's small-object allocator now returns an arena to
995 the system ``free()`` when all memory within an arena becomes unused
996 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
997 freed. Some applications will see a drop in virtual memory size now,
998 especially long-running applications that, from time to time, temporarily
999 use a large number of small objects. Note that when Python returns an
1000 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001001 platform C library will in turn return that memory to the operating system.
1002 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001003 appears to be effective at least on Microsoft C and gcc-based systems.
1004 Thanks to Evan Jones for hard work and patience.
1005
Georg Brandl533ff6f2006-03-08 18:09:27 +00001006- Patch #1434038: property() now uses the getter's docstring if there is
1007 no "doc" argument given. This makes it possible to legitimately use
1008 property() as a decorator to produce a read-only property.
1009
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001010- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1011 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1012 of requiring an int or long in slicing and a few other contexts, enabling
1013 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1014
Neal Norwitz995acdf2006-03-07 05:01:00 +00001015- Fixed various bugs reported by Coverity's Prevent tool.
1016
Brett Cannonbf364092006-03-01 04:25:17 +00001017- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1018 new exception base class, BaseException, which has a new message attribute.
1019 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1020 Raising a string exception now raises a DeprecationWarning.
1021
Thomas Woutersfb609f42006-02-28 16:37:25 +00001022- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1023 explicitly relative, using 'from .module import name' to mean 'from the same
1024 package as this module is in. Imports without dots still default to the
1025 old relative-then-absolute, unless 'from __future__ import
1026 absolute_import' is used.
1027
Brett Cannona7446e32006-02-27 23:39:10 +00001028- Properly check if 'warnings' raises an exception (usually when a filter set
1029 to "error" is triggered) when raising a warning for raising string
1030 exceptions.
1031
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001032- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001033 The name was removed from Include/code.h.
1034
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001035- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001036
Guido van Rossum1968ad32006-02-25 22:38:04 +00001037- Patch 1433928:
1038 - The copy module now "copies" function objects (as atomic objects).
1039 - dict.__getitem__ now looks for a __missing__ hook before raising
1040 KeyError.
1041
Tim Peters84ef21c2006-02-28 20:39:06 +00001042- PEP 343: with statement implemented. Needs ``from __future__ import
1043 with_statement``. Use of 'with' as a variable will generate a warning.
1044 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001045 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001046 The following objects have __context__ methods:
1047 - The built-in file type.
1048 - The thread.LockType type.
1049 - The following types defined by the threading module:
1050 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1051 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001052
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001053- Fix the encodings package codec search function to only search
1054 inside its own package. Fixes problem reported in patch #1433198.
1055
1056 Note: Codec packages should implement and register their own
1057 codec search function. PEP 100 has the details.
1058
Tim Peters9ea89d22006-06-04 03:26:02 +00001059- PEP 353: Using ``Py_ssize_t`` as the index type.
1060
1061- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1062 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1063 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1064 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1065 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001066
Neal Norwitzfc76d632006-01-10 06:03:13 +00001067- Patch #1400181, fix unicode string formatting to not use the locale.
1068 This is how string objects work. u'%f' could use , instead of .
1069 for the decimal point. Now both strings and unicode always use periods.
1070
Neal Norwitz671b9e32006-01-09 07:07:12 +00001071- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1072 configure would break checking curses.h.
1073
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001074- Bug #959576: The pwd module is now builtin. This allows Python to be
1075 built on UNIX platforms without $HOME set.
1076
Neal Norwitzc10978f2005-12-19 06:07:16 +00001077- Bug #1072182, fix some potential problems if characters are signed.
1078
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001079- Bug #889500, fix line number on SyntaxWarning for global declarations.
1080
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001081- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1082
Neal Norwitze7214a12005-12-18 05:03:17 +00001083- Support for converting hex strings to floats no longer works.
1084 This was not portable. float('0x3') now raises a ValueError.
1085
Barry Warsaw2a38a862005-12-18 01:27:35 +00001086- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001087 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001088 is now displayed in interactive prompt banner.
1089
Georg Brandlfa166682005-12-17 21:45:17 +00001090- Implementation of PEP 341 - Unification of try/except and try/finally.
1091 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001092 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001093
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001094- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1095 now encodes backslash correctly.
1096
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001097- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1098
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001099- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001100 and long longs.
1101
Neal Norwitz67715f02005-11-09 06:59:35 +00001102- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001103 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001104 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001105
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001106- Replaced most Unicode charmap codecs with new ones using the
1107 new Unicode translate string feature in the builtin charmap
1108 codec; the codecs were created from the mapping tables available
1109 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1110 encodings now include a mapping for the Apple logo)
1111
Tim Peterse3547fd2005-12-16 23:13:57 +00001112- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001113
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001114- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001115
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001116- A new AST parser implementation was completed. The abstract
1117 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001118 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001119
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001120- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001121 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1122
Neal Norwitz708e51a2005-10-03 04:48:15 +00001123- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1124
Neal Norwitz11bd1192005-10-03 00:54:56 +00001125- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1126 Provide a warning when a directory is passed on the command line.
1127
Neal Norwitz40d37812005-10-02 01:48:49 +00001128- Fix segfault with invalid coding.
1129
1130- SF bug #772896: unknown encoding results in MemoryError.
1131
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001132- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001133 supported a __len__() method which evaluated to False when the iterator
1134 was empty.
1135
Guido van Rossum630db602005-09-20 18:49:54 +00001136- On 64-bit platforms, when __len__() returns a value that cannot be
1137 represented as a C int, raise OverflowError.
1138
Skip Montanarof8948ca2005-09-19 03:54:46 +00001139- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001140 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001141
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001142- SF bug #893549: parsing keyword arguments was broken with a few format
1143 codes.
1144
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001145- Changes donated by Elemental Security to make it work on AIX 5.3
1146 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1147 bug #105470: test_pwd fails on 64bit system (Opteron).
1148
Guido van Rossum539c6622005-09-14 17:49:54 +00001149- Changes donated by Elemental Security to make it work on HP-UX 11 on
1150 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1151
Georg Brandl4550b8d2005-08-26 06:43:52 +00001152- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001153 (fixes bug #1119418).
1154
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001155- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1156
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001157- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1158 exceptions that cause a function to exit.
1159
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001160- The implementation of set() and frozenset() was revised to use its
1161 own internal data structure. Memory consumption is reduced by 1/3
1162 and there are modest speed-ups as well. The API is unchanged.
1163
Tim Petersde7990b2005-07-17 23:45:23 +00001164- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1165
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001166- SF bug #1229429: PyObject_CallMethod failed to decrement some
1167 reference counts in some error exit cases.
1168
Tim Petersecc6e6a2005-07-10 22:30:55 +00001169- SF bug #1185883: Python's small-object memory allocator took over
1170 a block managed by the platform C library whenever a realloc specified
1171 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001172 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001173 portable way to copy data from the C-managed block into Python's
1174 small-object space without risking a memory fault. Python's small-object
1175 realloc now leaves such blocks under the control of the platform C
1176 realloc.
1177
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001178- SF bug #1232517: An overflow error was not detected properly when
1179 attempting to convert a large float to an int in os.utime().
1180
Raymond Hettinger3296e692005-06-29 23:29:56 +00001181- SF bug #1224347: hex longs now print with lowercase letters just
1182 like their int counterparts.
1183
Michael W. Hudson188d4362005-06-20 16:52:57 +00001184- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1185 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1186 interpreter states; back out that fix and do a better job (see
1187 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1188 for a longer write-up of the problem).
1189
Michael W. Hudsondf888462005-06-03 14:41:55 +00001190- SF patch #1180995: marshal now uses a binary format by default when
1191 serializing floats.
1192
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001193- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1194 the routines that promise to produce IEEE 754 binary representations
1195 of floats now simply copy bytes around.
1196
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001197- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1198 278.
1199
Brett Cannonc3647ac2005-04-26 03:45:26 +00001200- patch #1109424: int, long, float, complex, and unicode now check for the
1201 proper magic slot for type conversions when subclassed. Previously the
1202 magic slot was ignored during conversion. Semantics now match the way
1203 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001204 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001205 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001206 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001207
Barry Warsawc8d907c2005-04-19 23:43:40 +00001208- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1209 NULL, now raise an AttributeError when attempting to set or delete the
1210 attribute. Previously a TypeError was raised, but this was inconsistent
1211 with the equivalent pure-Python implementation.
1212
Michael W. Hudson774479c2005-04-18 08:46:17 +00001213- It is now safe to call PyGILState_Release() before
1214 PyEval_InitThreads() (note that if there is reason to believe there
1215 are multiple threads around you still must call PyEval_InitThreads()
1216 before using the Python API; this fix is for extension modules that
1217 have no way of knowing if Python is multi-threaded yet).
1218
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001219- Typing Ctrl-C whilst raw_input() was waiting in a build with threads

1227
Raymond Hettinger96229b12005-03-11 06:49:40 +00001228- Added two new builtins, any() and all().
1229

Brett Cannonf4189912005-04-09 02:30:16 +00001231 (e.g., ``class C(): pass`` is no longer a syntax error).
1232 Patch #1176012 added support to the 'parser' module and 'compiler' package
1233 (thanks to logistix for that added support).

1242
Martin v. Löwisff232d72005-03-03 09:24:38 +00001243- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1244
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001245- Bug #1124295: the __name__ attribute of file objects was

1250
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001251- min() and max() now support key= arguments with the same meaning as in

1260 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001261
Jeremy Hyltonab630502005-02-04 18:44:06 +00001262- The parser did not complain about future statements in illegal
1263 positions. It once again reports a syntax error if a future
1264 statement occurs after anything other than a doc string.
1265
Neil Schemenauercf52c072005-08-12 17:34:58 +00001266- Change the %s format specifier for str objects so that it returns a
1267 unicode instance if the argument is not an instance of basestring and
1268 calling __str__ on the argument returns a unicode instance.
1269
Tim Petersf4e69282006-02-27 17:15:31 +00001270- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1271 current thread state when the auto-GIL-state machinery knows about
1272 it (since the thread state is being deleted, continuing to remember it
1273 can't help, but can hurt if another thread happens to get created with
1274 the same thread id).

1482 in attribute values.
1483
Anthony Baxterc51ee692006-04-01 00:57:31 +00001484- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001485 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001486 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001487 module will not be built.
1488
Tim Petersc17976e2006-04-01 00:26:53 +00001489- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1490 aren't officially supported here, and trying to use them will probably
1491 raise an exception some day. But dicts have been allowed, and "mostly
1492 worked", so support for them won't go away without warning.
1493
Georg Brandl338ef7d2006-03-31 18:42:16 +00001494- Bug #1445068: getpass.getpass() can now be given an explicit stream
1495 argument to specify where to write the prompt.
1496
Georg Brandl22ec80b2006-03-31 18:25:44 +00001497- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1503 key to be used for signing the uploaded code.
1504
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001505- Queue.Queue objects now support .task_done() and .join() methods
1506 to make it easier to monitor when daemon threads have completed
1507 processing all enqueued tasks. Patch #1455676.
1508
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001509- popen2.Popen objects now preserve the command in a .cmd attribute.
1510
Thomas Hellerc61c0492006-03-22 10:09:27 +00001511- Added the ctypes ffi package.
1512
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001513- email 4.0 package now integrated. This is largely the same as the email 3.0
1514 package that was included in Python 2.3, except that PEP 8 module names are
1515 now used (e.g. mail.message instead of email.Message). The MIME classes
1516 have been moved to a subpackage (e.g. email.mime.text instead of
1517 email.MIMEText). The old names are still supported for now. Several
1518 deprecated Message methods have been removed and lots of bugs have been
1519 fixed. More details can be found in the email package documentation.
1520
Walter Dörwald40108c92006-03-27 08:15:44 +00001521- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1522 (a subclass of tuple) that provides incremental decoders and encoders
1523 (a way to use stateful codecs without the stream API). Python functions
1524 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1525 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1526 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001527
Walter Dörwald067db482006-03-15 22:17:27 +00001528- Patch #1359365: Calling next() on a closed StringIO.String object raises
1529 a ValueError instead of a StopIteration now (like file and cString.String do).
1530 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1531 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001532
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001533- A regrtest option -w was added to re-run failed tests in verbose mode.

1539 grew an optional 'generation' argument.
1540
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00001541- A library msilib to generate Windows Installer files, and a distutils

1545 and helpful context managers nested() and closing().
1546

Martin v. Löwis3e865952006-01-24 15:51:21 +00001581 specifications, raises IOErrors when proxies for unsupported protocols
1582 are defined, and uses the https proxy on https redirections.

1601 LoadError as documented, instead of IOError. For compatibility,
1602 LoadError subclasses IOError.
1603
Brett Cannon3cbd0382005-12-16 22:49:23 +00001604- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001605 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1606 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1607 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1608 Ronald L. Rivest offered this advice for Python:
1609
1610 "The consensus of researchers in this area (at least as
1611 expressed at the NIST Hash Function Workshop 10/31/05),
1612 is that SHA-256 is a good choice for the time being, but
1613 that research should continue, and other alternatives may
1614 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001615
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001616- Added a subset of Fredrik Lundh's ElementTree package. Available

1669 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001670 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001671

1685
Georg Brandla4a8b822005-07-15 09:13:21 +00001686- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
1687 parameter, but uses the usual "kwargs=None".
1688
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001689- textwrap now processes text chunks at O(n) speed instead of O(n**2).

1693 to W3C name (404 -> 'Not Found'). RFE #1216944.
1694
Georg Brandl9e43acf2005-07-04 17:16:07 +00001695- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1696 as this can cause problems with apps closing all file descriptors.

1709 Bug #1224621.
1710
Raymond Hettinger68c04532005-06-10 11:05:19 +00001711- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001712 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001713 the generate_tokens() function now accepts a callable argument that
1714 terminates by raising StopIteration.
1715
Georg Brandl9166e1a2005-06-04 09:20:03 +00001716- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1719 component of the path.
1720
Skip Montanaro174dd222005-05-14 20:54:16 +00001721- Patch #1120353: The xmlrpclib module provides better, more transparent,

1724 class at all.
1725
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001726- distutils.commands.upload was added to support uploading distribution

1736
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001737- Bug #1163325: Decimal infinities failed to hash. Attempting to

1774
Guido van Rossumd0641422005-02-03 15:01:24 +00001775- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1776 disables recursive traversal through instance attributes, which can
1777 be exploited in various ways.
1778
Tim Peterse3547fd2005-12-16 23:13:57 +00001779- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001780 flags on the HTTP listening socket.
1781
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001782- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1783 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1784
Fred Drakefbdeaad2006-07-29 16:56:15 +00001785- Patches #893642, #1039083: add allow_none, encoding arguments to
1786 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.

1789
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001790- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1791
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001792- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1793
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001794- Enhancements to the csv module:
1795
1796 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001797 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001798 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001799 + Dialect parameter parsing has been re-implemented to improve error
1800 reporting.
1801 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1802 dictates.
1803 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001804 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001805 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001806 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1807 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001808 + reader now allows \r characters to be quoted (previously it only allowed
1809 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001810 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001811 + Dialect classes passed to the module are no longer instantiated by
1812 the module before being parsed (the former validation scheme required
1813 this, but the mechanism was unreliable).
1814 + The dialect registry now contains instances of the internal
1815 C-coded dialect type, rather than references to python objects.
1816 + the internal c-coded dialect type is now immutable.
1817 + register_dialect now accepts the same keyword dialect specifications
1818 as the reader and writer, allowing the user to register dialects
1819 without first creating a dialect class.
1820 + a configurable limit to the size of parsed fields has been added -
1821 previously, an unmatched quote character could result in the entire
1822 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001823 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001824 the parser field size limit (returning the former limit). The initial
1825 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001826 + A line_num attribute has been added to the reader object, which tracks
1827 the number of lines read from the source iterator. This is not
1828 the same as the number of records returned, as records can span
1829 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001830 + reader and writer objects were not being registered with the cyclic-GC.
1831 This has been fixed.
1832
Brett Cannone6539c42005-01-08 02:43:53 +00001833- _DummyThread objects in the threading module now delete self.__block that is
1834 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1835 lock primitives tend to be limited in number and thus should not be wasted on
1836 a _DummyThread object. Fixes bug #1089632.
1837
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001838- The imghdr module now detects Exif files.
1839
Raymond Hettinger6065d322004-12-20 23:51:53 +00001840- StringIO.truncate() now correctly adjusts the size attribute.
1841 (Bug #951915).
1842
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001843- locale.py now uses an updated locale alias table (built using
1844 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1845 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001846 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001847
Raymond Hettinger3557f422004-12-07 12:02:02 +00001848- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1849
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001850- the pickle module no longer accepts the deprecated None option in the
1851 args tuple returned by __reduce__().
1852
Brett Cannon84667c02004-12-07 03:25:18 +00001853- optparse now optionally imports gettext. This allows its use in setup.py.
1854
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001855- the pickle module no longer uses the deprecated bin parameter.
1856
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001857- the shelve module no longer uses the deprecated binary parameter.
1858
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001859- the pstats module no longer uses the deprecated ignore() method.
1860
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001861- the filecmp module no longer uses the deprecated use_statcache argument.
1862
Raymond Hettinger664347b2004-12-04 21:21:53 +00001863- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1864 extended or overridden by subclasses. Formerly, the subclassed method would
1865 be ignored by the rest of the module. (Bug #1078905).
1866
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001867- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001868 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001869
Walter Dörwald36733692004-12-22 12:50:50 +00001870- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1871 once when a size argument is given. This prevents a buffer overflow in the
1872 tokenizer with very long source lines.
1873
Barry Warsaw538561e2006-01-01 21:48:54 +00001874- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1875 immediately after creating the object, without any intervening
1876 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001877
Skip Montanaro05885812005-01-16 20:48:27 +00001878- The reconvert.quote function can now emit triple-quoted strings. The
1879 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001880
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001881- ``UserString.MutableString`` now supports negative indices in
1882 ``__setitem__`` and ``__delitem__``
1883
Greg Ward40407942005-03-05 02:53:17 +00001884- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1885 correctly.
1886
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001887- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1888 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1889 character even if the user has passed a size parameter to get a proper
1890 line ending. Remove the special handling of a "\r\n" that has been split
1891 between two lines.
1892
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001893- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1894 about illegal code points. The codec now supports PEP 293 style error
1895 handlers.
1896
Walter Dörwald78a78b02005-09-01 12:04:29 +00001897- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001898 from the input stream, so that the output is a byte string in the correct
1899 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001900
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001901- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1902 considering it exactly like a '*'.
1903
Walter Dörwald007f8df2005-10-09 19:42:27 +00001904- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1905 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001906
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001907- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1908
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001909- Patch #1413711: Certain patterns of differences were making difflib
1910 touch the recursion limit.
1911
Walter Dörwald58917a62006-03-31 15:26:22 +00001912- Bug #947906: An object oriented interface has been added to the calendar
1913 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001914 called as a script (e.g. via ``python -mcalendar``). Localized month and
1915 weekday names can be ouput (even if an exotic encoding is used) using
1916 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001917

1925
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001926- Build support for Win64-AMD64 was added.
1927
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001928- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1929
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001930- Patch #881820: look for openpty and forkpty also in libbsd.
1931
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001932- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1933 The zlib module is now builtin on Windows.
1934
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001935- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1936
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001937- Bug #1189330: configure did not correctly determine the necessary
1938 value of LINKCC if python was built with GCC 4.0.
1939
Trent Mick8321b422005-07-26 02:29:21 +00001940- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1941 vulnerability in zlib 1.2.1 and 1.2.2.
1942
Brett Cannon08cd5982005-04-24 22:26:38 +00001943- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1944 flags that change binary compatibility. Changes were also made to
1945 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001946 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001947
Bob Ippolitoed233462005-03-29 13:47:59 +00001948- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1949 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1950 no longer exists). This configure patch makes things right.
1951
Martin v. Löwise2713be2005-03-08 15:03:08 +00001952- Bug #1158607: Build with --disable-unicode again.
1953
Brett Cannon46d96232005-02-16 00:07:19 +00001954- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1955 defined. Discovered as a result of not being able to build on OS X.
1956
Brett Cannon516592f2004-12-07 00:42:59 +00001957- setup.py now uses the directories specified in LDFLAGS using the -L option
1958 and in CPPFLAGS using the -I option for adding library and include
1959 directories, respectively, for compiling extension modules against. This has
1960 led to the core being compiled using the values in CPPFLAGS. It also removes
1961 the need for the special-casing of both DarwinPorts and Fink for darwin since
1962 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1963 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1964 Fink, ``-I/opt/local/include`` for DarwinPorts).
1965
Brett Cannon43802422005-02-10 20:48:03 +00001966- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1967 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1968 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1969 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001971C API
1972-----
1973
Tim Petersc9d78aa2006-03-26 23:27:58 +00001974- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1975 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1976 is obtained via the ``PyObject_`` family, it must be released via the
1977 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1978 always been officially true, but when Python's small-object allocator was
1979 introduced, an attempt was made to cater to a few extension modules
1980 discovered at the time that obtained memory via ``PyObject_New`` but
1981 released it via ``PyMem_DEL``. It's years later, and if such code still
1982 exists it will fail now (probably with segfaults, but calling wrong
1983 low-level memory management functions can yield many symptoms).
1984
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001985- Added a C API for set and frozenset objects.
1986
Raymond Hettinger66517482004-12-03 11:45:13 +00001987- Removed PyRange_New().

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001989- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1990 mapping argument now. This string is used as a mapping table. Byte values
1991 greater than the length of the string and 0xFFFE are treated as undefined
1992 mappings.
