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.
19
Georg Brandl7e3ba2a2006-08-06 08:23:54 +000020- Bug #1535165: fixed a segfault in input() and raw_input() when
21 sys.stdin is closed.
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
58Tests
59-----
60

Fred Drake53912162006-07-29 13:22:49 +000085What's New in Python 2.5 beta 3?
86================================
Neal Norwitza1f10902006-07-12 07:28:29 +000087
Anthony Baxter5d32a9f2006-08-02 07:43:09 +000088*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +000089
90Core and builtins
91-----------------
92
Neal Norwitzc5e060d2006-08-02 06:14:22 +000093- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t, it previously
94 returned a long (see PEP 353).
95
Neal Norwitzf71ec5a2006-07-30 06:57:04 +000096- Bug #1515471: string.replace() accepts character buffers again.
97
Neal Norwitz07aadb12006-07-30 06:55:48 +000098- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
99 This provides the proper warning for struct.pack().
100 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
101
Neal Norwitz0d62a062006-07-30 06:53:31 +0000102- Patch #1531113: Fix augmented assignment with yield expressions.
103 Also fix a SystemError when trying to assign to yield expressions.
104
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000105- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
106 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
107 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
108 excessive filesystem operations during imports.
109
Tim Petersbc24eee2006-07-27 01:14:53 +0000110- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
111 operations on signed longs that are formally undefined by C.
112 Unfortunately, at least one compiler now cares about that, so complicated
113 the code to make that compiler happy again.
114
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000115- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
116
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000117- Patch #1232023: Stop including current directory in search
118 path on Windows.
119
Neal Norwitze1fdb322006-07-21 05:32:28 +0000120- Fix some potential crashes found with failmalloc.
121
Neal Norwitze7563102006-07-17 01:00:16 +0000122- Fix warnings reported by Klocwork's static analysis tool.
123
Neal Norwitz84be93b2006-07-16 01:50:38 +0000124- Bug #1512814, Fix incorrect lineno's when code within a function
125 had more than 255 blank lines.
126
Georg Brandl9dceedb2006-07-12 15:31:17 +0000127- Patch #1521179: Python now accepts the standard options ``--help`` and
128 ``--version`` as well as ``/?`` on Windows.
129
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000130- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000131 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000132 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000133
Tim Peters112aad32006-07-19 00:03:19 +0000134- Bug #1524317: Compiling Python ``--without-threads`` failed.
135 The Python core compiles again then, and, in a build without threads, the
136 new ``sys._current_frames()`` returns a dictionary with one entry,
137 mapping the faux "thread id" 0 to the current frame.
138
Ronald Oussoren3075e162006-07-25 20:28:55 +0000139- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000140
Ronald Oussoren3075e162006-07-25 20:28:55 +0000141
Neal Norwitza1f10902006-07-12 07:28:29 +0000142Library
143-------
144
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000145- Correction of patch #1455898: In the mbcs decoder, set final=False
146 for stream decoder, but final=True for the decode function.
147
Georg Brandl07fec3a2006-08-01 18:49:24 +0000148- os.urandom no longer masks unrelated exceptions like SystemExit or
149 KeyboardInterrupt.
150
Martin v. Löwis4e678382006-07-30 13:00:31 +0000151- Bug #1525866: Don't copy directory stat times in
152 shutil.copytree on Windows
153
Georg Brandle34ac7c2006-07-30 11:07:23 +0000154- Bug #1002398: The documentation for os.path.sameopenfile now correctly
155 refers to file descriptors, not file objects.
156
Fred Drakefbdeaad2006-07-29 16:56:15 +0000157- Rename of the xml package to xmlcore, and the import hackery done to
158 make it appear at both names, has been removed. Bug #1511497,
159 #1513611, and probably others.
160
Georg Brandledd9b0d2006-07-29 09:33:26 +0000161- Bug #1441397: The compiler module now recognizes module and function
162 docstrings correctly as it did in Python 2.4.
163
Tim Peters6f681472006-07-27 23:44:37 +0000164- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
165 lost that tests are sorted by name before being run. This rarely
166 matters for well-written tests, but can create baffling symptoms if
167 side effects from one test to the next affect outcomes. ``DocTestFinder``
168 has been changed to sort the list of tests it returns.
169
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000170- The distutils version has been changed to 2.5.0, and are now kept
171 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000172
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000173- Bug #978833: Really close underlying socket in _socketobject.close.
174
Georg Brandl0619a322006-07-26 07:40:17 +0000175- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
176 with title().
177
Georg Brandlcf0c1722006-07-26 07:23:32 +0000178- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
179 to recursive calls and call it with the failing package name.
180
Martin v. Löwis0b483032006-07-25 09:53:12 +0000181- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
182
Georg Brandlc13c34c2006-07-24 14:09:56 +0000183- Patch #1515343: Fix printing of deprecated string exceptions with a
184 value in the traceback module.
185
Greg Ward48fae7a2006-07-23 16:05:51 +0000186- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
187
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000188- Patch #1524429: Use repr() instead of backticks in Tkinter again.
189
Brett Cannoncaebe222006-07-18 04:41:36 +0000190- Bug #1520914: Change time.strftime() to accept a zero for any position in its
191 argument tuple. For arguments where zero is illegal, the value is forced to
192 the minimum value that is correct. This is to support an undocumented but
193 common way people used to fill in inconsequential information in the time
194 tuple pre-2.4.
195
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000196- Patch #1220874: Update the binhex module for Mach-O.
197
Barry Warsawb110bad2006-07-21 14:51:07 +0000198- The email package has improved RFC 2231 support, specifically for
199 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
200 (name*0=<blah>) parameter continuations. This may change the types of
201 values returned from email.message.Message.get_param() and friends.
202 Specifically in some cases where non-encoded continuations were used,
203 get_param() used to return a 3-tuple of (None, None, string) whereas now it
204 will just return the string (since non-encoded continuations don't have
205 charset and language parts).
206
207 Also, whereas % values were decoded in all parameter continuations, they are
208 now only decoded in encoded parameter parts.
209
Ronald Oussoren3075e162006-07-25 20:28:55 +0000210- Bug #1517990: IDLE keybindings on MacOS X now work correctly
211
212- Bug #1517996: IDLE now longer shows the default Tk menu when a
213 path browser, class browser or debugger is the frontmost window on MacOS X
214
Barry Warsaw00decd72006-07-27 23:43:15 +0000215- Patch #1520294: Support for getset and member descriptors in types.py,
216 inspect.py, and pydoc.py. Specifically, this allows for querying the type
217 of an object against these built-in types and more importantly, for getting
218 their docstrings printed in the interactive interpreter's help() function.

223
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000224- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
225 a socket operation on a socket with a timeout, the exception will be
226 caught correctly. Previously, the exception was not caught.
227
Thomas Heller1393d6a2006-07-28 21:43:20 +0000228- Patch #1529514: The _ctypes extension is now compiled on more
229 openbsd target platforms.
230
Tim Peters9cab5932006-07-28 00:30:00 +0000231- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
232 a memory leak, affecting pickles and deep copies.
233
Tim Petersbc24eee2006-07-27 01:14:53 +0000234- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

236
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000237- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
238
Thomas Hellerce049a02006-07-14 17:51:14 +0000239- Patch #1521817: Index range checking on ctypes arrays containing
240 exactly one element enabled again. This allows iterating over these
241 arrays, without the need to check the array size before.
242
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000243- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000244 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000245 /dev/null in certain cases; this is now fixed.
246
Thomas Heller47d7a062006-07-12 08:43:47 +0000247- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
248 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000249
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000250- Because of a misspelled preprocessor symbol, ctypes was always
251 compiled without thread support; this is now fixed.
252
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000253- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
254 methods now allow their database parameter to be None as the
255 sleepycat API allows.
256
Matt Flemingec926502006-07-28 11:27:27 +0000257- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
258 bluetooth API compared with Linux and FreeBSD.
259
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000260Tests
261-----
262
263- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
264 how long the test file should take to play. Now accepts taking 2.93 secs
265 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
266
Georg Brandl4793aa32006-07-28 18:31:39 +0000267- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
268 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
269 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000270

278
279- PythonLauncher now works correctly when the path to the script contains
280 characters that are treated specially by the shell (such as quotes).
281
282- Bug #1527397: PythonLauncher now launches scripts with the working directory
283 set to the directory that contains the script instead of the user home
284 directory. That latter was an implementation accident and not what users
285 expect.

306 and atof().
307
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000308- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
309 omit a default "error" argument for NULL pointer. This allows
310 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000311
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000312- Bug #1519018: 'as' is now validated properly in import statements.

Neal Norwitz28746ab2006-07-09 22:14:42 +0000314- On 64 bit systems, int literals that use less than 64 bits are
315 now ints rather than longs.
316
Neal Norwitzed657552006-07-10 00:04:44 +0000317- Bug #1512814, Fix incorrect lineno's when code at module scope

Tim Peters32a83612006-07-10 21:08:24 +0000320- New function ``sys._current_frames()`` returns a dict mapping thread
321 id to topmost thread stack frame. This is for expert use, and is
322 especially useful for debugging application deadlocks. The functionality
323 was previously available in Fazal Majid's ``threadframe`` extension
324 module, but it wasn't possible to do this in a wholly threadsafe way from
325 an extension.

342
Thomas Woutersadd19112006-07-05 11:03:49 +0000343- string.Template() now correctly handles tuple-values. Previously,
344 multi-value tuples would raise an exception and single-value tuples would
345 be treated as the value they contain, instead.
346
Martin v. Löwisede77f52006-07-03 13:01:35 +0000347- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

372
Brett Cannon53ab5b72006-06-22 16:49:14 +0000373- Bug #1510580: The 'warnings' module improperly required that a Warning
374 category be either a types.ClassType and a subclass of Warning. The proper
375 check is just that it is a subclass with Warning as the documentation states.
376
Georg Brandlad29e632006-06-21 17:45:17 +0000377- The compiler module now correctly compiles the new try-except-finally

390-----------------
391
Tim Peters112aad32006-07-19 00:03:19 +0000392- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
393 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
394 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000395
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000396- Assigning None to pointer type fields in ctypes structures possible
397 overwrote the wrong fields, this is fixed now.
398
399- Fixed a segfault in _ctypes when ctypes.wintypes were imported
400 on non-Windows platforms.
401
402- Bug #1518190: The ctypes.c_void_p constructor now accepts any
403 integer or long, without range checking.
404
405- Patch #1517790: It is now possible to use custom objects in the ctypes
406 foreign function argtypes sequence as long as they provide a from_param
407 method, no longer is it required that the object is a ctypes type.
408
409- The '_ctypes' extension module now works when Python is configured
410 with the --without-threads option.
411
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000412- Bug #1513646: os.access on Windows now correctly determines write

427
Tim Peters32a83612006-07-10 21:08:24 +0000428- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000429 Previously, the slight difference could cause compilation errors of the
430 'zlib' module on systems with more than one version of zlib.
431
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000432- The MSI compileall step was fixed to also support a TARGETDIR

463Core and builtins
464-----------------
465
Georg Brandla56b9152006-06-19 06:35:54 +0000466- Patch #1507676: Error messages returned by invalid abstract object operations
467 (such as iterating over an integer) have been improved and now include the
468 type of the offending object to help with debugging.
469
Brett Cannonea3912b2006-06-13 21:46:41 +0000470- Bug #992017: A classic class that defined a __coerce__() method that returned
471 its arguments swapped would infinitely recurse and segfault the interpreter.
472
Neal Norwitz909eb122006-06-12 02:13:21 +0000473- Fix the socket tests so they can be run concurrently.
474
Neal Norwitzb9845e72006-06-12 02:11:18 +0000475- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000476 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000477
Brett Cannon22565aa2006-06-09 22:31:23 +0000478- Bug #532646: object.__call__() will continue looking for the __call__
479 attribute on objects until one without one is found. This leads to recursion
480 when you take a class and set its __call__ attribute to an instance of the
481 class. Originally fixed for classic classes, but this fix is for new-style.
482 Removes the infinite_rec_3 crasher.
483
Georg Brandl24250812006-06-09 18:45:48 +0000484- The string and unicode methods startswith() and endswith() now accept
485 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
486
Brett Cannonde3b0522006-06-08 17:00:45 +0000487- Buffer objects, at the C level, never used the char buffer
488 implementation even when the char buffer for the wrapped object was
489 explicitly requested (originally returned the read or write buffer).
490 Now a TypeError is raised if the char buffer is not present but is
491 requested.
492
Georg Brandlddbaa662006-06-04 21:56:52 +0000493- Patch #1346214: Statements like "if 0: suite" are now again optimized
494 away like they were in Python 2.4.
495
Georg Brandlb7c8f542006-05-27 12:30:25 +0000496- Builtin exceptions are now full-blown new-style classes instead of
497 instances pretending to be classes, which speeds up exception handling
498 by about 80% in comparison to 2.5a2.
499
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000500- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
501 Unicode 4.1.
502
Georg Brandlf4ef1162006-05-26 18:03:31 +0000503- Patch #921466: sys.path_importer_cache is now used to cache valid and
504 invalid file paths for the built-in import machinery which leads to
505 fewer open calls on startup.
506
Tim Peters696cf432006-05-24 21:10:40 +0000507- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
508 of-2 bases. The largest speedup is for inputs with about 1000 decimal
509 digits. Conversion from non-power-of-2 bases remains quadratic-time in
510 the number of input digits (it was and remains linear-time for bases
511 2, 4, 8, 16 and 32).
512
Tim Petersb713ec22006-05-23 18:45:30 +0000513- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
514 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
515 an integer close to ``sys.maxint``. This was repaired by patch
516 #1335972, which also gives a nice speedup.
517
Richard Jonescebbefc2006-05-23 18:28:17 +0000518- Patch #1337051: reduced size of frame objects.
519
520- PyErr_NewException now accepts a tuple of base classes as its
521 "base" parameter.
522
Richard Jones7c88dcc2006-05-23 10:37:38 +0000523- Patch #876206: function call speedup by retaining allocated frame
524 objects.
525
Georg Brandl7b90e162006-05-18 07:01:27 +0000526- Bug #1462152: file() now checks more thoroughly for invalid mode
527 strings and removes a possible "U" before passing the mode to the
528 C library function.
529
Neal Norwitz1004a532006-05-15 07:17:23 +0000530- Patch #1488312, Fix memory alignment problem on SPARC in unicode
531
Neal Norwitz373f0a72006-05-15 07:04:36 +0000532- Bug #1487966: Fix SystemError with conditional expression in assignment
533
Martin v. Löwis879768d2006-05-11 13:28:43 +0000534- WindowsError now has two error code attributes: errno, which carries
535 the error values from errno.h, and winerror, which carries the error
536 values from winerror.h. Previous versions put the winerror.h values
537 (from GetLastError()) into the errno attribute.
538
Martin v. Löwis77736712006-05-04 05:51:03 +0000539- Patch #1475845: Raise IndentationError for unexpected indent.
540
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000541- Patch #1479181: split open() and file() from being aliases for each other.
542
Tim Peters44bd9862006-06-01 13:49:23 +0000543- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
544 methods were always silently ignored by dictionaries when comparing keys.
545 They are now passed through (except when using the C API function
546 ``PyDict_GetItem()``, whose semantics did not change).
547
548- Bug #1456209: In some obscure cases it was possible for a class with a
549 custom ``__eq__()`` method to confuse dict internals when class instances
550 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
551 No, you don't have any code that did this ;-)

Brett Cannon6ee7d012006-06-08 16:23:04 +0000560- Change binascii.hexlify to accept a read-only buffer instead of only a char
561 buffer and actually follow its documentation.
562
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000563- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
564
Nick Coghlanc649ec52006-05-29 12:43:05 +0000565- Patch #1478788 (modified version): The functional extension module has
566 been renamed to _functools and a functools Python wrapper module added.
567 This provides a home for additional function related utilities that are
568 not specifically about functional programming. See PEP 309.
569
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000570- Patch #1493701: performance enhancements for struct module.

578 enabled builds on Windows and systems with Posix threads support.
579
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000580- On Win32, os.listdir now supports arbitrarily-long Unicode path names
581 (up to the system limit of 32K characters).
582
583- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
584 As a result, these functions now raise WindowsError instead of OSError.
585
Tim Peters7a822da2006-05-25 21:50:17 +0000586- ``time.clock()`` on Win64 should use the high-performance Windows
587 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
588 Windows platforms).
589
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000590- Calling Tk_Init twice is refused if the first call failed as that
591 may deadlock.
592
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000593- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
594 accept it without potentially using an uninitialized pointer.
595
596- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
597 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

607 results. It could previously incorrectly return 0 in some cases.
608 Fixes SF bug 1493322 (pybsddb bug 1184012).
609
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000610- bsddb: the bsddb.dbtables Modify method now raises the proper error and

Gregory P. Smith506f7b52006-06-15 08:52:32 +0000614- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000615 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000616 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
617 database calls that would previously deadlock. [SF python bug #775414]

638 classes.
639
Georg Brandl83cc0d02006-06-14 08:50:03 +0000640- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
641 mime.types file for determining MIME types.
642
Georg Brandl2605ca82006-06-14 06:08:31 +0000643- Bug #1339007: Shelf objects now don't raise an exception in their
644 __del__ method when initialization failed.
645
Martin v. Löwisd8251432006-06-14 05:21:04 +0000646- Patch #1455898: The MBCS codec now supports the incremental mode for
647 double-byte encodings.
648
Tim Peters43898b42006-06-14 04:09:25 +0000649- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
650 guarantee that adjacent triples in the return list always describe
651 non-adjacent blocks. Previously, a pair of matching blocks could end
652 up being described by multiple adjacent triples that formed a partition
653 of the matching pair.
654
Greg Ward0e0c9f42006-06-11 16:24:11 +0000655- Bug #1498146: fix optparse to handle Unicode strings in option help,
656 description, and epilog.
657
Greg Wardd1c797e2006-06-11 14:42:41 +0000658- Bug #1366250: minor optparse documentation error.
659
Greg Ward7f547402006-06-11 00:40:49 +0000660- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
661 clarify docs.
662
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000663- The wsgiref package has been added to the standard library.
664
Nick Coghlan676725d2006-06-08 13:54:49 +0000665- The functions update_wrapper() and wraps() have been added to the functools
666 module. These make it easier to copy relevant metadata from the original
667 function when writing wrapper functions.
668
Tim Petersd6a9eef2006-06-05 01:48:21 +0000669- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
670 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000671
Martin v. Löwis3f767792006-06-04 19:36:28 +0000672- Patch #1359618: Speed up charmap encoder by using a trie structure
673 for lookup.
674
Tim Petersd609b1a2006-06-02 23:22:51 +0000675- The functions in the ``pprint`` module now sort dictionaries by key
676 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
677 if and only if its display required more than one line, although that
678 wasn't documented. The new behavior increases predictability; e.g.,
679 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
680
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000681- Patch #1497027: try HTTP digest auth before basic auth in urllib2

685 default HTTP and HTTPS ports.
686
George Yoshidaf3c65de2006-05-28 16:39:09 +0000687- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.

690
Georg Brandlb89316f2006-05-17 15:51:16 +0000691- Patch #1180296: Two new functions were added to the locale module:
692 format_string() to get the effect of "format % items" but locale-aware,
693 and currency() to format a monetary number with currency sign.
694
Georg Brandle3a25832006-05-17 14:56:04 +0000695- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
696 and several features added, such as speed and geometry control.
697
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000698- Patch #1488881: add support for external file objects in bz2 compressed
699 tarfiles.
700
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000701- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
702 stdout arguments, making it possible to redirect input and output
703 for remote debugging.
704
705- Patch #1484695: Update the tarfile module to version 0.8. This fixes
706 a couple of issues, notably handling of long file names using the
707 GNU LONGNAME extension.
708
709- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
710 new flag when ``name`` is already the name of an option flag.
711
712- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
713 package.
714
715- Patch #1472854: make the rlcompleter.Completer class usable on non-
716 UNIX platforms.
717
718- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
719
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000720- Bug #1472827: correctly escape newlines and tabs in attribute values in
721 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000751What's New in Python 2.5 alpha 2?
752=================================
753
754*Release date: 27-APR-2006*
755
756Core and builtins
757-----------------
758
Thomas Heller1b046642006-04-18 18:51:06 +0000759- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
760 by converting these apis from macros into exported functions again:
761
762 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
763 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
764 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
765 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
766 PyRun_String Py_CompileString
767
Martin v. Löwis45294a92006-04-18 06:24:08 +0000768- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
769
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000770- All uses of PyStructSequence_InitType have been changed to initialize
771 the type objects only once, even if the interpreter is initialized
772 multiple times.
773
Neal Norwitz61546162006-04-14 05:20:28 +0000774- Bug #1454485, array.array('u') could crash the interpreter. This was
775 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
776 to unicode when it didn't make sense. 'u#' now requires a unicode string.
777
778- Py_UNICODE is unsigned. It was always documented as unsigned, but
779 due to a bug had a signed value in previous versions.
780
Tim Peters3a5e8b12006-04-11 01:44:07 +0000781- Patch #837242: ``id()`` of any Python object always gives a positive
782 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
783 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000784 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000785 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000786
Tim Peters3a5e8b12006-04-11 01:44:07 +0000787 def __hash__(self):
788 return id(self) # WRONG
789
790 because a hash result must be a (short) Python int but it was always
791 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000792 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000793 was always usable as a hash value before this patch. That's no longer
794 necessarily so.
795
796- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000797 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000798 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000799 #1454844)
800
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000801- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
802 involving generators that have paused outside of any ``try`` or ``with``
803 blocks. (In 2.5a1, a paused generator that was part of a reference
804 cycle could not be garbage collected, regardless of whether it was
805 paused in a ``try`` or ``with`` block.)

819 the cachesize parameter.
820
821- Bug #1149413: bsddb.*open() no longer raises an exception when using
822 a temporary db (file=None) with the 'n' flag to truncate on open.
823
824- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
825 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000826
Armin Rigoa9017c32006-04-19 11:50:27 +0000827- Patch #1062014: AF_UNIX sockets under Linux have a special

832
Peter Astrand7d1d4362006-07-14 14:04:45 +0000833- Bug #1223937: subprocess.CalledProcessError reports the exit status
834 of the process using the returncode attribute, instead of
835 abusing errno.
836
Tim Peters711bf302006-04-25 03:31:36 +0000837- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
838 a doctest to be skipped (the code is not run, and the expected output
839 or exception is ignored).
840
Nick Coghlanda2268f2006-04-24 04:37:15 +0000841- Fixed contextlib.nested to cope with exceptions being raised and
842 caught inside exit handlers.
843
Greg Wardab05edc2006-04-23 03:47:58 +0000844- Updated optparse module to Optik 1.5.1 (allow numeric constants in
845 hex, octal, or binary; add ``append_const`` action; keep going if
846 gettext cannot be imported; added ``OptionParser.destroy()`` method;
847 added ``epilog`` for better help generation).
848
Tim Peters21fbd572006-04-21 21:18:10 +0000849- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
850 called from a thread spawned as a side effect of importing a module.
851
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000852- The pydoc module now supports documenting packages contained in
853 .zip or .egg files.
854
855- The pkgutil module now has several new utility functions, such
856 as ``walk_packages()`` to support working with packages that are either
857 in the filesystem or zip files.
858
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000859- The mailbox module can now modify and delete messages from
860 mailboxes, in addition to simply reading them. Thanks to Gregory
861 K. Johnson for writing the code, and to the 2005 Google Summer of
862 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000863
Tim Petersc7605f22006-04-17 21:12:33 +0000864- The ``__del__`` method of class ``local`` in module ``_threading_local``
865 returned before accomplishing any of its intended cleanup.
866
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000867- Patch #790710: Add breakpoint command lists in pdb.

875
Phillip J. Eby47032112006-04-11 01:07:43 +0000876- The warnings, linecache, inspect, traceback, site, and doctest modules
877 were updated to work correctly with modules imported from zipfiles or

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000900- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
901 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000902 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000903 CXX from --with-cxx-main, see description in README.
904

Nick Coghlan27ec1a72006-04-24 04:32:47 +0000919- test_cmd_line now checks operation of the -m and -c command switches
920
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000921- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
922 it separately and by hand. It also wasn't cleaning up its changes to
923 the current Decimal context.
924
Thomas Woutersabd08882006-04-26 15:53:30 +0000925- regrtest.py now has a -M option to run tests that test the new limits of
926 containers, on 64-bit architectures. Running these tests is only sensible
927 on 64-bit machines with more than two gigabytes of memory. The argument
928 passed is the maximum amount of memory for the tests to use.

942 and attempted to bring other PEP 343 related documentation into
943 line with the implementation and/or python-dev discussions.
944
Tim Peters8dc73d22006-04-24 02:03:16 +0000945- Bug #1337990: clarified that ``doctest`` does not support examples
946 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000949What's New in Python 2.5 alpha 1?
950=================================
951
Anthony Baxterebed3f62006-04-03 15:03:44 +0000952*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000953
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000954Core and builtins
955-----------------
956
Nick Coghlan43832302006-04-23 17:04:07 +0000957- PEP 338: -m command line switch now delegates to runpy.run_module
958 allowing it to support modules in packages and zipfiles
959
Martin v. Löwisc661b882006-04-20 04:54:23 +0000960- On Windows, .DLL is not an accepted file name extension for
961 extension modules anymore; extensions are only found if they
962 end in .PYD.
963
Martin v. Löwisea62d252006-04-03 10:56:49 +0000964- Bug #1421664: sys.stderr.encoding is now set to the same value as
965 sys.stdout.encoding.
966
Neal Norwitz92e212f2006-04-03 04:48:37 +0000967- __import__ accepts keyword arguments.
968
Georg Brandlccadf842006-03-31 18:54:53 +0000969- Patch #1460496: round() now accepts keyword arguments.
970
Anthony Baxter262c00a2006-03-30 10:53:17 +0000971- Fixed bug #1459029 - unicode reprs were double-escaped.
972
Hye-Shik Changd478f342006-03-23 12:32:36 +0000973- Patch #1396919: The system scope threads are reenabled on FreeBSD
974 5.4 and later versions.
975
Neal Norwitze98ccf62006-03-23 05:39:47 +0000976- Bug #1115379: Compiling a Unicode string with an encoding declaration
977 now gives a SyntaxError.
978
Georg Brandlabd1ff82006-03-18 07:59:59 +0000979- Previously, Python code had no easy way to access the contents of a
980 cell object. Now, a ``cell_contents`` attribute has been added
981 (closes patch #1170323).
982
Tim Peterscf79aac2006-03-16 01:14:46 +0000983- Patch #1123430: Python's small-object allocator now returns an arena to
984 the system ``free()`` when all memory within an arena becomes unused
985 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
986 freed. Some applications will see a drop in virtual memory size now,
987 especially long-running applications that, from time to time, temporarily
988 use a large number of small objects. Note that when Python returns an
989 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000990 platform C library will in turn return that memory to the operating system.
991 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000992 appears to be effective at least on Microsoft C and gcc-based systems.
993 Thanks to Evan Jones for hard work and patience.
994
Georg Brandl533ff6f2006-03-08 18:09:27 +0000995- Patch #1434038: property() now uses the getter's docstring if there is
996 no "doc" argument given. This makes it possible to legitimately use
997 property() as a decorator to produce a read-only property.
998
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000999- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1000 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1001 of requiring an int or long in slicing and a few other contexts, enabling
1002 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1003
Neal Norwitz995acdf2006-03-07 05:01:00 +00001004- Fixed various bugs reported by Coverity's Prevent tool.
1005
Brett Cannonbf364092006-03-01 04:25:17 +00001006- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1007 new exception base class, BaseException, which has a new message attribute.
1008 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1009 Raising a string exception now raises a DeprecationWarning.
1010
Thomas Woutersfb609f42006-02-28 16:37:25 +00001011- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1012 explicitly relative, using 'from .module import name' to mean 'from the same
1013 package as this module is in. Imports without dots still default to the
1014 old relative-then-absolute, unless 'from __future__ import
1015 absolute_import' is used.
1016
Brett Cannona7446e32006-02-27 23:39:10 +00001017- Properly check if 'warnings' raises an exception (usually when a filter set
1018 to "error" is triggered) when raising a warning for raising string
1019 exceptions.
1020
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001021- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001022 The name was removed from Include/code.h.
1023
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001024- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001025
Guido van Rossum1968ad32006-02-25 22:38:04 +00001026- Patch 1433928:
1027 - The copy module now "copies" function objects (as atomic objects).
1028 - dict.__getitem__ now looks for a __missing__ hook before raising
1029 KeyError.
1030
Tim Peters84ef21c2006-02-28 20:39:06 +00001031- PEP 343: with statement implemented. Needs ``from __future__ import
1032 with_statement``. Use of 'with' as a variable will generate a warning.
1033 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001034 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001035 The following objects have __context__ methods:
1036 - The built-in file type.
1037 - The thread.LockType type.
1038 - The following types defined by the threading module:
1039 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1040 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001041
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001042- Fix the encodings package codec search function to only search
1043 inside its own package. Fixes problem reported in patch #1433198.
1044
1045 Note: Codec packages should implement and register their own
1046 codec search function. PEP 100 has the details.
1047
Tim Peters9ea89d22006-06-04 03:26:02 +00001048- PEP 353: Using ``Py_ssize_t`` as the index type.
1049
1050- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1051 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1052 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1053 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1054 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001055
Neal Norwitzfc76d632006-01-10 06:03:13 +00001056- Patch #1400181, fix unicode string formatting to not use the locale.
1057 This is how string objects work. u'%f' could use , instead of .
1058 for the decimal point. Now both strings and unicode always use periods.
1059
Neal Norwitz671b9e32006-01-09 07:07:12 +00001060- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1061 configure would break checking curses.h.
1062
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001063- Bug #959576: The pwd module is now builtin. This allows Python to be
1064 built on UNIX platforms without $HOME set.
1065
Neal Norwitzc10978f2005-12-19 06:07:16 +00001066- Bug #1072182, fix some potential problems if characters are signed.
1067
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001068- Bug #889500, fix line number on SyntaxWarning for global declarations.
1069
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001070- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1071
Neal Norwitze7214a12005-12-18 05:03:17 +00001072- Support for converting hex strings to floats no longer works.
1073 This was not portable. float('0x3') now raises a ValueError.
1074
Barry Warsaw2a38a862005-12-18 01:27:35 +00001075- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001076 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001077 is now displayed in interactive prompt banner.
1078
Georg Brandlfa166682005-12-17 21:45:17 +00001079- Implementation of PEP 341 - Unification of try/except and try/finally.
1080 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001081 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001082
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001083- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1084 now encodes backslash correctly.
1085
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001086- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1087
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001088- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001089 and long longs.
1090
Neal Norwitz67715f02005-11-09 06:59:35 +00001091- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001092 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001093 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001094
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001095- Replaced most Unicode charmap codecs with new ones using the
1096 new Unicode translate string feature in the builtin charmap
1097 codec; the codecs were created from the mapping tables available
1098 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1099 encodings now include a mapping for the Apple logo)
1100
Tim Peterse3547fd2005-12-16 23:13:57 +00001101- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001102
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001103- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001104
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001105- A new AST parser implementation was completed. The abstract
1106 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001107 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001108
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001109- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001110 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1111
Neal Norwitz708e51a2005-10-03 04:48:15 +00001112- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1113
Neal Norwitz11bd1192005-10-03 00:54:56 +00001114- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1115 Provide a warning when a directory is passed on the command line.
1116
Neal Norwitz40d37812005-10-02 01:48:49 +00001117- Fix segfault with invalid coding.
1118
1119- SF bug #772896: unknown encoding results in MemoryError.
1120
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001121- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001122 supported a __len__() method which evaluated to False when the iterator
1123 was empty.
1124
Guido van Rossum630db602005-09-20 18:49:54 +00001125- On 64-bit platforms, when __len__() returns a value that cannot be
1126 represented as a C int, raise OverflowError.
1127
Skip Montanarof8948ca2005-09-19 03:54:46 +00001128- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001129 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001130
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001131- SF bug #893549: parsing keyword arguments was broken with a few format
1132 codes.
1133
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001134- Changes donated by Elemental Security to make it work on AIX 5.3
1135 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1136 bug #105470: test_pwd fails on 64bit system (Opteron).
1137
Guido van Rossum539c6622005-09-14 17:49:54 +00001138- Changes donated by Elemental Security to make it work on HP-UX 11 on
1139 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1140
Georg Brandl4550b8d2005-08-26 06:43:52 +00001141- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001142 (fixes bug #1119418).
1143
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001144- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1145
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001146- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1147 exceptions that cause a function to exit.
1148
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001149- The implementation of set() and frozenset() was revised to use its
1150 own internal data structure. Memory consumption is reduced by 1/3
1151 and there are modest speed-ups as well. The API is unchanged.
1152
Tim Petersde7990b2005-07-17 23:45:23 +00001153- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1154
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001155- SF bug #1229429: PyObject_CallMethod failed to decrement some
1156 reference counts in some error exit cases.
1157
Tim Petersecc6e6a2005-07-10 22:30:55 +00001158- SF bug #1185883: Python's small-object memory allocator took over
1159 a block managed by the platform C library whenever a realloc specified
1160 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001161 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001162 portable way to copy data from the C-managed block into Python's
1163 small-object space without risking a memory fault. Python's small-object
1164 realloc now leaves such blocks under the control of the platform C
1165 realloc.
1166
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001167- SF bug #1232517: An overflow error was not detected properly when
1168 attempting to convert a large float to an int in os.utime().
1169
Raymond Hettinger3296e692005-06-29 23:29:56 +00001170- SF bug #1224347: hex longs now print with lowercase letters just
1171 like their int counterparts.
1172
Michael W. Hudson188d4362005-06-20 16:52:57 +00001173- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1174 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1175 interpreter states; back out that fix and do a better job (see
1176 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1177 for a longer write-up of the problem).
1178
Michael W. Hudsondf888462005-06-03 14:41:55 +00001179- SF patch #1180995: marshal now uses a binary format by default when
1180 serializing floats.
1181
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001182- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1183 the routines that promise to produce IEEE 754 binary representations
1184 of floats now simply copy bytes around.
1185
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001186- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1187 278.
1188
Brett Cannonc3647ac2005-04-26 03:45:26 +00001189- patch #1109424: int, long, float, complex, and unicode now check for the
1190 proper magic slot for type conversions when subclassed. Previously the
1191 magic slot was ignored during conversion. Semantics now match the way
1192 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001193 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001194 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001195 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001196
Barry Warsawc8d907c2005-04-19 23:43:40 +00001197- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1198 NULL, now raise an AttributeError when attempting to set or delete the
1199 attribute. Previously a TypeError was raised, but this was inconsistent
1200 with the equivalent pure-Python implementation.
1201
Michael W. Hudson774479c2005-04-18 08:46:17 +00001202- It is now safe to call PyGILState_Release() before
1203 PyEval_InitThreads() (note that if there is reason to believe there
1204 are multiple threads around you still must call PyEval_InitThreads()
1205 before using the Python API; this fix is for extension modules that
1206 have no way of knowing if Python is multi-threaded yet).
1207
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001208- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1209 disabled caused a crash.

1262 can't help, but can hurt if another thread happens to get created with
1263 the same thread id).

Tim Peters3a5e8b12006-04-11 01:44:07 +00001475 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001476 module will not be built.
1477
Tim Petersc17976e2006-04-01 00:26:53 +00001478- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1479 aren't officially supported here, and trying to use them will probably
1480 raise an exception some day. But dicts have been allowed, and "mostly
1481 worked", so support for them won't go away without warning.
1482
Georg Brandl338ef7d2006-03-31 18:42:16 +00001483- Bug #1445068: getpass.getpass() can now be given an explicit stream
1484 argument to specify where to write the prompt.
1485
Georg Brandl22ec80b2006-03-31 18:25:44 +00001486- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1492 key to be used for signing the uploaded code.
1493
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001494- Queue.Queue objects now support .task_done() and .join() methods
1495 to make it easier to monitor when daemon threads have completed
1496 processing all enqueued tasks. Patch #1455676.
1497
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001498- popen2.Popen objects now preserve the command in a .cmd attribute.
1499
Thomas Hellerc61c0492006-03-22 10:09:27 +00001500- Added the ctypes ffi package.
1501
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001502- email 4.0 package now integrated. This is largely the same as the email 3.0
1503 package that was included in Python 2.3, except that PEP 8 module names are
1504 now used (e.g. mail.message instead of email.Message). The MIME classes
1505 have been moved to a subpackage (e.g. email.mime.text instead of
1506 email.MIMEText). The old names are still supported for now. Several
1507 deprecated Message methods have been removed and lots of bugs have been
1508 fixed. More details can be found in the email package documentation.
1509
Walter Dörwald40108c92006-03-27 08:15:44 +00001510- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1511 (a subclass of tuple) that provides incremental decoders and encoders
1512 (a way to use stateful codecs without the stream API). Python functions
1513 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1514 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1515 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001516
Walter Dörwald067db482006-03-15 22:17:27 +00001517- Patch #1359365: Calling next() on a closed StringIO.String object raises
1518 a ValueError instead of a StopIteration now (like file and cString.String do).
1519 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1520 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001521
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001522- A regrtest option -w was added to re-run failed tests in verbose mode.

1528 grew an optional 'generation' argument.
1529
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00001530- A library msilib to generate Windows Installer files, and a distutils

1590 LoadError as documented, instead of IOError. For compatibility,
1591 LoadError subclasses IOError.
1592

Tim Peterse3547fd2005-12-16 23:13:57 +00001594 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1595 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1596 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1597 Ronald L. Rivest offered this advice for Python:
1598
1599 "The consensus of researchers in this area (at least as
1600 expressed at the NIST Hash Function Workshop 10/31/05),
1601 is that SHA-256 is a good choice for the time being, but
1602 that research should continue, and other alternatives may
1603 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001604
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001605- Added a subset of Fredrik Lundh's ElementTree package. Available

1658 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001659 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001660

1676 parameter, but uses the usual "kwargs=None".
1677
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001678- textwrap now processes text chunks at O(n) speed instead of O(n**2).

1699
Raymond Hettinger68c04532005-06-10 11:05:19 +00001700- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001701 roundtrip from lexed tokens back to Python source code. In addition,

1708 component of the path.
1709
Skip Montanaro174dd222005-05-14 20:54:16 +00001710- Patch #1120353: The xmlrpclib module provides better, more transparent,

1713 class at all.
1714
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001715- distutils.commands.upload was added to support uploading distribution

1724 work as expected.
1725
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001726- Bug #1163325: Decimal infinities failed to hash. Attempting to

Martin v. Löwisa4dac402005-03-03 11:39:45 +00001741 profile.py if available.
1742
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001743- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1744

1759
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001760- Patch #1049151: xdrlib now unpacks booleans as True or False.
1761
Raymond Hettingerbab41432005-02-05 01:31:19 +00001762- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1763
Guido van Rossumd0641422005-02-03 15:01:24 +00001764- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1765 disables recursive traversal through instance attributes, which can
1766 be exploited in various ways.
1767
Tim Peterse3547fd2005-12-16 23:13:57 +00001768- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001769 flags on the HTTP listening socket.
1770
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001771- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1772 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1773
Fred Drakefbdeaad2006-07-29 16:56:15 +00001774- Patches #893642, #1039083: add allow_none, encoding arguments to
1775 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001776

1778
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001779- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1780
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001781- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1782
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001783- Enhancements to the csv module:
1784
1785 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001786 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001787 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001788 + Dialect parameter parsing has been re-implemented to improve error
1789 reporting.
1790 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1791 dictates.
1792 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001793 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001794 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001795 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1796 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001797 + reader now allows \r characters to be quoted (previously it only allowed
1798 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001799 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001800 + Dialect classes passed to the module are no longer instantiated by
1801 the module before being parsed (the former validation scheme required
1802 this, but the mechanism was unreliable).
1803 + The dialect registry now contains instances of the internal
1804 C-coded dialect type, rather than references to python objects.
1805 + the internal c-coded dialect type is now immutable.
1806 + register_dialect now accepts the same keyword dialect specifications
1807 as the reader and writer, allowing the user to register dialects
1808 without first creating a dialect class.
1809 + a configurable limit to the size of parsed fields has been added -
1810 previously, an unmatched quote character could result in the entire
1811 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001812 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001813 the parser field size limit (returning the former limit). The initial
1814 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001815 + A line_num attribute has been added to the reader object, which tracks
1816 the number of lines read from the source iterator. This is not
1817 the same as the number of records returned, as records can span
1818 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001819 + reader and writer objects were not being registered with the cyclic-GC.
1820 This has been fixed.
1821
Brett Cannone6539c42005-01-08 02:43:53 +00001822- _DummyThread objects in the threading module now delete self.__block that is
1823 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1824 lock primitives tend to be limited in number and thus should not be wasted on
1825 a _DummyThread object. Fixes bug #1089632.
1826
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001827- The imghdr module now detects Exif files.
1828
Raymond Hettinger6065d322004-12-20 23:51:53 +00001829- StringIO.truncate() now correctly adjusts the size attribute.
1830 (Bug #951915).
1831
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001832- locale.py now uses an updated locale alias table (built using
1833 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1834 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001835 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001836
Raymond Hettinger3557f422004-12-07 12:02:02 +00001837- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1838
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001839- the pickle module no longer accepts the deprecated None option in the
1840 args tuple returned by __reduce__().
1841
Brett Cannon84667c02004-12-07 03:25:18 +00001842- optparse now optionally imports gettext. This allows its use in setup.py.
1843
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001844- the pickle module no longer uses the deprecated bin parameter.
1845
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001846- the shelve module no longer uses the deprecated binary parameter.
1847
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001848- the pstats module no longer uses the deprecated ignore() method.
1849
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001850- the filecmp module no longer uses the deprecated use_statcache argument.
1851
Raymond Hettinger664347b2004-12-04 21:21:53 +00001852- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1853 extended or overridden by subclasses. Formerly, the subclassed method would
1854 be ignored by the rest of the module. (Bug #1078905).
1855
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001856- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001857 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001858
Walter Dörwald36733692004-12-22 12:50:50 +00001859- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1860 once when a size argument is given. This prevents a buffer overflow in the
1861 tokenizer with very long source lines.
1862
Barry Warsaw538561e2006-01-01 21:48:54 +00001863- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1864 immediately after creating the object, without any intervening
1865 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001866
Skip Montanaro05885812005-01-16 20:48:27 +00001867- The reconvert.quote function can now emit triple-quoted strings. The
1868 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001869
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001870- ``UserString.MutableString`` now supports negative indices in
1871 ``__setitem__`` and ``__delitem__``
1872
Greg Ward40407942005-03-05 02:53:17 +00001873- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1874 correctly.
1875
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001876- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1877 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1878 character even if the user has passed a size parameter to get a proper
1879 line ending. Remove the special handling of a "\r\n" that has been split
1880 between two lines.
1881
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001882- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1883 about illegal code points. The codec now supports PEP 293 style error
1884 handlers.
1885
Walter Dörwald78a78b02005-09-01 12:04:29 +00001886- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001887 from the input stream, so that the output is a byte string in the correct
1888 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001889
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001890- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1891 considering it exactly like a '*'.
1892
Walter Dörwald007f8df2005-10-09 19:42:27 +00001893- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1894 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001895
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001896- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1897
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001898- Patch #1413711: Certain patterns of differences were making difflib
1899 touch the recursion limit.
1900
Walter Dörwald58917a62006-03-31 15:26:22 +00001901- Bug #947906: An object oriented interface has been added to the calendar
1902 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001903 called as a script (e.g. via ``python -mcalendar``). Localized month and
1904 weekday names can be ouput (even if an exotic encoding is used) using
1905 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001906
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001907Build
1908-----
1909
Neal Norwitz602d3392006-03-31 08:21:40 +00001910- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1911 by using -mieee gcc option.
1912
Martin v. Löwis86d66262006-02-17 08:40:11 +00001913- Patch #1432345: Make python compile on DragonFly.
1914
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001915- Build support for Win64-AMD64 was added.
1916
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001917- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1918
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001919- Patch #881820: look for openpty and forkpty also in libbsd.
1920
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001921- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1922 The zlib module is now builtin on Windows.
1923
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001924- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1925
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001926- Bug #1189330: configure did not correctly determine the necessary
1927 value of LINKCC if python was built with GCC 4.0.
1928
Trent Mick8321b422005-07-26 02:29:21 +00001929- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1930 vulnerability in zlib 1.2.1 and 1.2.2.
1931
Brett Cannon08cd5982005-04-24 22:26:38 +00001932- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1933 flags that change binary compatibility. Changes were also made to
1934 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001935 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001936
Bob Ippolitoed233462005-03-29 13:47:59 +00001937- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1938 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1939 no longer exists). This configure patch makes things right.
1940
Martin v. Löwise2713be2005-03-08 15:03:08 +00001941- Bug #1158607: Build with --disable-unicode again.
1942
Brett Cannon46d96232005-02-16 00:07:19 +00001943- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1944 defined. Discovered as a result of not being able to build on OS X.
1945
Brett Cannon516592f2004-12-07 00:42:59 +00001946- setup.py now uses the directories specified in LDFLAGS using the -L option
1947 and in CPPFLAGS using the -I option for adding library and include
1948 directories, respectively, for compiling extension modules against. This has
1949 led to the core being compiled using the values in CPPFLAGS. It also removes
1950 the need for the special-casing of both DarwinPorts and Fink for darwin since
1951 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1952 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1953 Fink, ``-I/opt/local/include`` for DarwinPorts).
1954
Brett Cannon43802422005-02-10 20:48:03 +00001955- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1956 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1957 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1958 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001960C API
1961-----
1962
Tim Petersc9d78aa2006-03-26 23:27:58 +00001963- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1964 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1965 is obtained via the ``PyObject_`` family, it must be released via the
1966 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1967 always been officially true, but when Python's small-object allocator was
1968 introduced, an attempt was made to cater to a few extension modules
1969 discovered at the time that obtained memory via ``PyObject_New`` but
1970 released it via ``PyMem_DEL``. It's years later, and if such code still
1971 exists it will fail now (probably with segfaults, but calling wrong
1972 low-level memory management functions can yield many symptoms).
1973
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001974- Added a C API for set and frozenset objects.
1975
Raymond Hettinger66517482004-12-03 11:45:13 +00001976- Removed PyRange_New().
1977
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001978- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1979 mapping argument now. This string is used as a mapping table. Byte values
1980 greater than the length of the string and 0xFFFE are treated as undefined
1981 mappings.
