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

Fred Drake53912162006-07-29 13:22:49 +000070What's New in Python 2.5 beta 3?
71================================
Neal Norwitza1f10902006-07-12 07:28:29 +000072
Anthony Baxter5d32a9f2006-08-02 07:43:09 +000073*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +000074
75Core and builtins
76-----------------
77
Neal Norwitzc5e060d2006-08-02 06:14:22 +000078- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t, it previously
79 returned a long (see PEP 353).
80
Neal Norwitzf71ec5a2006-07-30 06:57:04 +000081- Bug #1515471: string.replace() accepts character buffers again.
82
Neal Norwitz07aadb12006-07-30 06:55:48 +000083- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
84 This provides the proper warning for struct.pack().
85 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
86
Neal Norwitz0d62a062006-07-30 06:53:31 +000087- Patch #1531113: Fix augmented assignment with yield expressions.
88 Also fix a SystemError when trying to assign to yield expressions.
89
Phillip J. Ebyf7575d02006-07-28 21:12:07 +000090- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
91 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
92 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
93 excessive filesystem operations during imports.
94
Tim Petersbc24eee2006-07-27 01:14:53 +000095- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
96 operations on signed longs that are formally undefined by C.
97 Unfortunately, at least one compiler now cares about that, so complicated
98 the code to make that compiler happy again.
99
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000100- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
101
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000102- Patch #1232023: Stop including current directory in search
103 path on Windows.
104
Neal Norwitze1fdb322006-07-21 05:32:28 +0000105- Fix some potential crashes found with failmalloc.
106
Neal Norwitze7563102006-07-17 01:00:16 +0000107- Fix warnings reported by Klocwork's static analysis tool.
108
Neal Norwitz84be93b2006-07-16 01:50:38 +0000109- Bug #1512814, Fix incorrect lineno's when code within a function
110 had more than 255 blank lines.
111
Georg Brandl9dceedb2006-07-12 15:31:17 +0000112- Patch #1521179: Python now accepts the standard options ``--help`` and
113 ``--version`` as well as ``/?`` on Windows.
114
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000115- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000116 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000117 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000118
Tim Peters112aad32006-07-19 00:03:19 +0000119- Bug #1524317: Compiling Python ``--without-threads`` failed.
120 The Python core compiles again then, and, in a build without threads, the
121 new ``sys._current_frames()`` returns a dictionary with one entry,
122 mapping the faux "thread id" 0 to the current frame.
123
Ronald Oussoren3075e162006-07-25 20:28:55 +0000124- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000125
Ronald Oussoren3075e162006-07-25 20:28:55 +0000126
Neal Norwitza1f10902006-07-12 07:28:29 +0000127Library
128-------
129
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000130- Correction of patch #1455898: In the mbcs decoder, set final=False
131 for stream decoder, but final=True for the decode function.
132
Georg Brandl07fec3a2006-08-01 18:49:24 +0000133- os.urandom no longer masks unrelated exceptions like SystemExit or
134 KeyboardInterrupt.
135
Martin v. Löwis4e678382006-07-30 13:00:31 +0000136- Bug #1525866: Don't copy directory stat times in
137 shutil.copytree on Windows
138
Georg Brandle34ac7c2006-07-30 11:07:23 +0000139- Bug #1002398: The documentation for os.path.sameopenfile now correctly
140 refers to file descriptors, not file objects.
141
Fred Drakefbdeaad2006-07-29 16:56:15 +0000142- Rename of the xml package to xmlcore, and the import hackery done to
143 make it appear at both names, has been removed. Bug #1511497,
144 #1513611, and probably others.
145
Georg Brandledd9b0d2006-07-29 09:33:26 +0000146- Bug #1441397: The compiler module now recognizes module and function
147 docstrings correctly as it did in Python 2.4.
148
Tim Peters6f681472006-07-27 23:44:37 +0000149- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
150 lost that tests are sorted by name before being run. This rarely
151 matters for well-written tests, but can create baffling symptoms if
152 side effects from one test to the next affect outcomes. ``DocTestFinder``
153 has been changed to sort the list of tests it returns.
154
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000155- The distutils version has been changed to 2.5.0, and are now kept
156 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000157
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000158- Bug #978833: Really close underlying socket in _socketobject.close.
159
Georg Brandl0619a322006-07-26 07:40:17 +0000160- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
161 with title().
162
Georg Brandlcf0c1722006-07-26 07:23:32 +0000163- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
164 to recursive calls and call it with the failing package name.
165
Martin v. Löwis0b483032006-07-25 09:53:12 +0000166- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
167
Georg Brandlc13c34c2006-07-24 14:09:56 +0000168- Patch #1515343: Fix printing of deprecated string exceptions with a
169 value in the traceback module.
170
Greg Ward48fae7a2006-07-23 16:05:51 +0000171- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
172
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000173- Patch #1524429: Use repr() instead of backticks in Tkinter again.
174
Brett Cannoncaebe222006-07-18 04:41:36 +0000175- Bug #1520914: Change time.strftime() to accept a zero for any position in its
176 argument tuple. For arguments where zero is illegal, the value is forced to
177 the minimum value that is correct. This is to support an undocumented but
178 common way people used to fill in inconsequential information in the time
179 tuple pre-2.4.
180
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000181- Patch #1220874: Update the binhex module for Mach-O.
182
Barry Warsawb110bad2006-07-21 14:51:07 +0000183- The email package has improved RFC 2231 support, specifically for
184 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
185 (name*0=<blah>) parameter continuations. This may change the types of
186 values returned from email.message.Message.get_param() and friends.
187 Specifically in some cases where non-encoded continuations were used,
188 get_param() used to return a 3-tuple of (None, None, string) whereas now it
189 will just return the string (since non-encoded continuations don't have
190 charset and language parts).
191
192 Also, whereas % values were decoded in all parameter continuations, they are
193 now only decoded in encoded parameter parts.
194
Ronald Oussoren3075e162006-07-25 20:28:55 +0000195- Bug #1517990: IDLE keybindings on MacOS X now work correctly
196
197- Bug #1517996: IDLE now longer shows the default Tk menu when a
198 path browser, class browser or debugger is the frontmost window on MacOS X
199
Barry Warsaw00decd72006-07-27 23:43:15 +0000200- Patch #1520294: Support for getset and member descriptors in types.py,
201 inspect.py, and pydoc.py. Specifically, this allows for querying the type
202 of an object against these built-in types and more importantly, for getting
203 their docstrings printed in the interactive interpreter's help() function.

207-----------------
208
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000209- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
210 a socket operation on a socket with a timeout, the exception will be
211 caught correctly. Previously, the exception was not caught.
212
Thomas Heller1393d6a2006-07-28 21:43:20 +0000213- Patch #1529514: The _ctypes extension is now compiled on more
214 openbsd target platforms.
215
Tim Peters9cab5932006-07-28 00:30:00 +0000216- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
217 a memory leak, affecting pickles and deep copies.
218
Tim Petersbc24eee2006-07-27 01:14:53 +0000219- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

221
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000222- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
223
Thomas Hellerce049a02006-07-14 17:51:14 +0000224- Patch #1521817: Index range checking on ctypes arrays containing
225 exactly one element enabled again. This allows iterating over these
226 arrays, without the need to check the array size before.
227
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000228- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000229 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000230 /dev/null in certain cases; this is now fixed.
231
Thomas Heller47d7a062006-07-12 08:43:47 +0000232- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
233 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000234
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000235- Because of a misspelled preprocessor symbol, ctypes was always
236 compiled without thread support; this is now fixed.
237
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000238- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
239 methods now allow their database parameter to be None as the
240 sleepycat API allows.
241
Matt Flemingec926502006-07-28 11:27:27 +0000242- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
243 bluetooth API compared with Linux and FreeBSD.
244
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000245Tests
246-----
247
248- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
249 how long the test file should take to play. Now accepts taking 2.93 secs
250 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
251
Georg Brandl4793aa32006-07-28 18:31:39 +0000252- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
253 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
254 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000255

259- Bug #1439538: Drop usage of test -e in configure as it is not portable.
260
Ronald Oussoren26cad082006-08-01 21:00:57 +0000261Mac
262---
263
264- PythonLauncher now works correctly when the path to the script contains
265 characters that are treated specially by the shell (such as quotes).
266
267- Bug #1527397: PythonLauncher now launches scripts with the working directory
268 set to the directory that contains the script instead of the user home
269 directory. That latter was an implementation accident and not what users
270 expect.

Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000281- Bug #1441486: The literal representation of -(sys.maxint - 1)
282 again evaluates to a int object, not a long.
283
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000284- Bug #1501934: The scope of global variables that are locally assigned
285 using augmented assignment is now correctly determined.
286
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000287- Bug #927248: Recursive method-wrapper objects can now safely
288 be released.
289
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000290- Bug #1417699: Reject locale-specific decimal point in float()
291 and atof().
292
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000293- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
294 omit a default "error" argument for NULL pointer. This allows
295 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000296
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000297- Bug #1519018: 'as' is now validated properly in import statements.
298
Neal Norwitz28746ab2006-07-09 22:14:42 +0000299- On 64 bit systems, int literals that use less than 64 bits are
300 now ints rather than longs.
301
Neal Norwitzed657552006-07-10 00:04:44 +0000302- Bug #1512814, Fix incorrect lineno's when code at module scope
303 started after line 256.
304
Tim Peters32a83612006-07-10 21:08:24 +0000305- New function ``sys._current_frames()`` returns a dict mapping thread
306 id to topmost thread stack frame. This is for expert use, and is
307 especially useful for debugging application deadlocks. The functionality
308 was previously available in Fazal Majid's ``threadframe`` extension
309 module, but it wasn't possible to do this in a wholly threadsafe way from
310 an extension.

Nick Coghlan2d792252006-07-06 13:47:18 +0000326- warnings.py now ignores ImportWarning by default
327
Thomas Woutersadd19112006-07-05 11:03:49 +0000328- string.Template() now correctly handles tuple-values. Previously,
329 multi-value tuples would raise an exception and single-value tuples would
330 be treated as the value they contain, instead.
331
Martin v. Löwisede77f52006-07-03 13:01:35 +0000332- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
333 even if some data are received.
334

345 is created.
346
Martin v. Löwis7596e832006-07-01 15:33:37 +0000347- Bug #1513223: .close() of a _socketobj now releases the underlying
348 socket again, which then gets closed as it becomes unreferenced.
349
Fred Drake10497c82006-06-29 02:57:48 +0000350- Bug #1504333: Make sgmllib support angle brackets in quoted
351 attribute values.
352
353- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
354 sgmllib ('[' and ']' were not accepted).
355
Georg Brandl1be63af2006-06-28 20:23:25 +0000356- Fix a bug in the turtle module's end_fill function.
357
Brett Cannon53ab5b72006-06-22 16:49:14 +0000358- Bug #1510580: The 'warnings' module improperly required that a Warning
359 category be either a types.ClassType and a subclass of Warning. The proper
360 check is just that it is a subclass with Warning as the documentation states.
361
Georg Brandlad29e632006-06-21 17:45:17 +0000362- The compiler module now correctly compiles the new try-except-finally
363 statement (bug #1509132).
364
Neal Norwitz60373cd2006-06-22 06:30:50 +0000365- The wsgiref package is now installed properly on Unix.
366
Vinay Sajip28e57612006-07-01 10:45:20 +0000367- A bug was fixed in logging.config.fileConfig() which caused a crash on
368 shutdown when fileConfig() was called multiple times.
369
Gerhard Häring762fbd32006-07-02 17:48:30 +0000370- The sqlite3 module did cut off data from the SQLite database at the first
371 null character before sending it to a custom converter. This has been fixed
372 now.

375-----------------
376
Tim Peters112aad32006-07-19 00:03:19 +0000377- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
378 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
379 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000380
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000381- Assigning None to pointer type fields in ctypes structures possible
382 overwrote the wrong fields, this is fixed now.
383
384- Fixed a segfault in _ctypes when ctypes.wintypes were imported
385 on non-Windows platforms.
386
387- Bug #1518190: The ctypes.c_void_p constructor now accepts any
388 integer or long, without range checking.
389
390- Patch #1517790: It is now possible to use custom objects in the ctypes
391 foreign function argtypes sequence as long as they provide a from_param
392 method, no longer is it required that the object is a ctypes type.
393
394- The '_ctypes' extension module now works when Python is configured
395 with the --without-threads option.
396
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000397- Bug #1513646: os.access on Windows now correctly determines write

399
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000400- Bug #1512695: cPickle.loads could crash if it was interrupted with
401 a KeyboardInterrupt.
402
Neal Norwitza12aa882006-07-06 06:45:08 +0000403- Bug #1296433: parsing XML with a non-default encoding and
404 a CharacterDataHandler could crash the interpreter in pyexpat.

410
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000411- Automate Windows build process for the Win64 SSL module.
412
Tim Peters32a83612006-07-10 21:08:24 +0000413- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000414 Previously, the slight difference could cause compilation errors of the
415 'zlib' module on systems with more than one version of zlib.
416
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000417- The MSI compileall step was fixed to also support a TARGETDIR
418 with spaces in it.

448Core and builtins
449-----------------
450
Georg Brandla56b9152006-06-19 06:35:54 +0000451- Patch #1507676: Error messages returned by invalid abstract object operations
452 (such as iterating over an integer) have been improved and now include the
453 type of the offending object to help with debugging.
454
Brett Cannonea3912b2006-06-13 21:46:41 +0000455- Bug #992017: A classic class that defined a __coerce__() method that returned
456 its arguments swapped would infinitely recurse and segfault the interpreter.
457
Neal Norwitz909eb122006-06-12 02:13:21 +0000458- Fix the socket tests so they can be run concurrently.
459
Neal Norwitzb9845e72006-06-12 02:11:18 +0000460- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000461 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000462
Brett Cannon22565aa2006-06-09 22:31:23 +0000463- Bug #532646: object.__call__() will continue looking for the __call__
464 attribute on objects until one without one is found. This leads to recursion
465 when you take a class and set its __call__ attribute to an instance of the
466 class. Originally fixed for classic classes, but this fix is for new-style.
467 Removes the infinite_rec_3 crasher.
468
Georg Brandl24250812006-06-09 18:45:48 +0000469- The string and unicode methods startswith() and endswith() now accept
470 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
471
Brett Cannonde3b0522006-06-08 17:00:45 +0000472- Buffer objects, at the C level, never used the char buffer
473 implementation even when the char buffer for the wrapped object was
474 explicitly requested (originally returned the read or write buffer).
475 Now a TypeError is raised if the char buffer is not present but is
476 requested.
477
Georg Brandlddbaa662006-06-04 21:56:52 +0000478- Patch #1346214: Statements like "if 0: suite" are now again optimized
479 away like they were in Python 2.4.
480
Georg Brandlb7c8f542006-05-27 12:30:25 +0000481- Builtin exceptions are now full-blown new-style classes instead of
482 instances pretending to be classes, which speeds up exception handling
483 by about 80% in comparison to 2.5a2.
484
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000485- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
486 Unicode 4.1.
487
Georg Brandlf4ef1162006-05-26 18:03:31 +0000488- Patch #921466: sys.path_importer_cache is now used to cache valid and
489 invalid file paths for the built-in import machinery which leads to
490 fewer open calls on startup.
491
Tim Peters696cf432006-05-24 21:10:40 +0000492- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
493 of-2 bases. The largest speedup is for inputs with about 1000 decimal
494 digits. Conversion from non-power-of-2 bases remains quadratic-time in
495 the number of input digits (it was and remains linear-time for bases
496 2, 4, 8, 16 and 32).
497
Tim Petersb713ec22006-05-23 18:45:30 +0000498- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
499 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
500 an integer close to ``sys.maxint``. This was repaired by patch
501 #1335972, which also gives a nice speedup.
502
Richard Jonescebbefc2006-05-23 18:28:17 +0000503- Patch #1337051: reduced size of frame objects.
504
505- PyErr_NewException now accepts a tuple of base classes as its
506 "base" parameter.
507
Richard Jones7c88dcc2006-05-23 10:37:38 +0000508- Patch #876206: function call speedup by retaining allocated frame
509 objects.
510
Georg Brandl7b90e162006-05-18 07:01:27 +0000511- Bug #1462152: file() now checks more thoroughly for invalid mode
512 strings and removes a possible "U" before passing the mode to the
513 C library function.
514
Neal Norwitz1004a532006-05-15 07:17:23 +0000515- Patch #1488312, Fix memory alignment problem on SPARC in unicode
516
Neal Norwitz373f0a72006-05-15 07:04:36 +0000517- Bug #1487966: Fix SystemError with conditional expression in assignment
518
Martin v. Löwis879768d2006-05-11 13:28:43 +0000519- WindowsError now has two error code attributes: errno, which carries
520 the error values from errno.h, and winerror, which carries the error
521 values from winerror.h. Previous versions put the winerror.h values
522 (from GetLastError()) into the errno attribute.
523
Martin v. Löwis77736712006-05-04 05:51:03 +0000524- Patch #1475845: Raise IndentationError for unexpected indent.
525
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000526- Patch #1479181: split open() and file() from being aliases for each other.
527
Tim Peters44bd9862006-06-01 13:49:23 +0000528- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
529 methods were always silently ignored by dictionaries when comparing keys.
530 They are now passed through (except when using the C API function
531 ``PyDict_GetItem()``, whose semantics did not change).
532
533- Bug #1456209: In some obscure cases it was possible for a class with a
534 custom ``__eq__()`` method to confuse dict internals when class instances
535 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
536 No, you don't have any code that did this ;-)

544
Brett Cannon6ee7d012006-06-08 16:23:04 +0000545- Change binascii.hexlify to accept a read-only buffer instead of only a char
546 buffer and actually follow its documentation.
547
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000548- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
549
Nick Coghlanc649ec52006-05-29 12:43:05 +0000550- Patch #1478788 (modified version): The functional extension module has
551 been renamed to _functools and a functools Python wrapper module added.
552 This provides a home for additional function related utilities that are
553 not specifically about functional programming. See PEP 309.
554
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000555- Patch #1493701: performance enhancements for struct module.

564
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000565- On Win32, os.listdir now supports arbitrarily-long Unicode path names
566 (up to the system limit of 32K characters).
567
568- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
569 As a result, these functions now raise WindowsError instead of OSError.
570
Tim Peters7a822da2006-05-25 21:50:17 +0000571- ``time.clock()`` on Win64 should use the high-performance Windows
572 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
573 Windows platforms).
574
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000575- Calling Tk_Init twice is refused if the first call failed as that
576 may deadlock.
577
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000578- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
579 accept it without potentially using an uninitialized pointer.
580
581- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
582 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

594
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000595- bsddb: the bsddb.dbtables Modify method now raises the proper error and

Gregory P. Smith506f7b52006-06-15 08:52:32 +0000599- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000600 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000601 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
602 database calls that would previously deadlock. [SF python bug #775414]

Georg Brandl83cc0d02006-06-14 08:50:03 +0000625- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
626 mime.types file for determining MIME types.
627
Georg Brandl2605ca82006-06-14 06:08:31 +0000628- Bug #1339007: Shelf objects now don't raise an exception in their
629 __del__ method when initialization failed.
630
Martin v. Löwisd8251432006-06-14 05:21:04 +0000631- Patch #1455898: The MBCS codec now supports the incremental mode for
632 double-byte encodings.
633
Tim Peters43898b42006-06-14 04:09:25 +0000634- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
635 guarantee that adjacent triples in the return list always describe
636 non-adjacent blocks. Previously, a pair of matching blocks could end
637 up being described by multiple adjacent triples that formed a partition
638 of the matching pair.
639
Greg Ward0e0c9f42006-06-11 16:24:11 +0000640- Bug #1498146: fix optparse to handle Unicode strings in option help,
641 description, and epilog.
642
Greg Wardd1c797e2006-06-11 14:42:41 +0000643- Bug #1366250: minor optparse documentation error.
644
Greg Ward7f547402006-06-11 00:40:49 +0000645- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
646 clarify docs.
647
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000648- The wsgiref package has been added to the standard library.
649
Nick Coghlan676725d2006-06-08 13:54:49 +0000650- The functions update_wrapper() and wraps() have been added to the functools
651 module. These make it easier to copy relevant metadata from the original
652 function when writing wrapper functions.
653
Tim Petersd6a9eef2006-06-05 01:48:21 +0000654- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
655 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000656
Martin v. Löwis3f767792006-06-04 19:36:28 +0000657- Patch #1359618: Speed up charmap encoder by using a trie structure
658 for lookup.
659
Tim Petersd609b1a2006-06-02 23:22:51 +0000660- The functions in the ``pprint`` module now sort dictionaries by key
661 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
662 if and only if its display required more than one line, although that
663 wasn't documented. The new behavior increases predictability; e.g.,
664 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
665
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000666- Patch #1497027: try HTTP digest auth before basic auth in urllib2
667 (thanks for J. J. Lee).
668
Georg Brandl2b330372006-05-28 20:23:12 +0000669- Patch #1496206: improve urllib2 handling of passwords with respect to
670 default HTTP and HTTPS ports.
671
George Yoshidaf3c65de2006-05-28 16:39:09 +0000672- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
673
Bob Ippolito7298f272006-05-23 18:43:47 +0000674- Patch #1281707: speed up gzip.readline.
675
Georg Brandlb89316f2006-05-17 15:51:16 +0000676- Patch #1180296: Two new functions were added to the locale module:
677 format_string() to get the effect of "format % items" but locale-aware,
678 and currency() to format a monetary number with currency sign.
679
Georg Brandle3a25832006-05-17 14:56:04 +0000680- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
681 and several features added, such as speed and geometry control.
682
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000683- Patch #1488881: add support for external file objects in bz2 compressed
684 tarfiles.
685
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000686- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
687 stdout arguments, making it possible to redirect input and output
688 for remote debugging.
689
690- Patch #1484695: Update the tarfile module to version 0.8. This fixes
691 a couple of issues, notably handling of long file names using the
692 GNU LONGNAME extension.
693
694- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
695 new flag when ``name`` is already the name of an option flag.
696
697- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
698 package.
699
700- Patch #1472854: make the rlcompleter.Completer class usable on non-
701 UNIX platforms.
702
703- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
704
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000705- Bug #1472827: correctly escape newlines and tabs in attribute values in
706 the saxutils.XMLGenerator class.

735
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000736What's New in Python 2.5 alpha 2?
737=================================
738
739*Release date: 27-APR-2006*
740
741Core and builtins
742-----------------
743
Thomas Heller1b046642006-04-18 18:51:06 +0000744- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
745 by converting these apis from macros into exported functions again:
746
747 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
748 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
749 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
750 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
751 PyRun_String Py_CompileString
752
Martin v. Löwis45294a92006-04-18 06:24:08 +0000753- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
754
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000755- All uses of PyStructSequence_InitType have been changed to initialize
756 the type objects only once, even if the interpreter is initialized
757 multiple times.
758
Neal Norwitz61546162006-04-14 05:20:28 +0000759- Bug #1454485, array.array('u') could crash the interpreter. This was
760 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
761 to unicode when it didn't make sense. 'u#' now requires a unicode string.
762
763- Py_UNICODE is unsigned. It was always documented as unsigned, but
764 due to a bug had a signed value in previous versions.
765
Tim Peters3a5e8b12006-04-11 01:44:07 +0000766- Patch #837242: ``id()`` of any Python object always gives a positive
767 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
768 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000769 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000770 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000771
Tim Peters3a5e8b12006-04-11 01:44:07 +0000772 def __hash__(self):
773 return id(self) # WRONG
774
775 because a hash result must be a (short) Python int but it was always
776 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000777 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000778 was always usable as a hash value before this patch. That's no longer
779 necessarily so.
780
781- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000782 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000783 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000784 #1454844)
785
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000786- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
787 involving generators that have paused outside of any ``try`` or ``with``
788 blocks. (In 2.5a1, a paused generator that was part of a reference
789 cycle could not be garbage collected, regardless of whether it was
790 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000792Extension Modules

796 is a macro.
797
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000798- Bug #1467952: os.listdir() now correctly raises an error if readdir()
799 fails with an error condition.
800
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000801- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
802
803- Bug #1117761: bsddb.*open() no longer raises an exception when using
804 the cachesize parameter.
805
806- Bug #1149413: bsddb.*open() no longer raises an exception when using
807 a temporary db (file=None) with the 'n' flag to truncate on open.
808
809- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
810 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000811
Armin Rigoa9017c32006-04-19 11:50:27 +0000812- Patch #1062014: AF_UNIX sockets under Linux have a special
813 abstract namespace that is now fully supported.

816-------
817
Peter Astrand7d1d4362006-07-14 14:04:45 +0000818- Bug #1223937: subprocess.CalledProcessError reports the exit status
819 of the process using the returncode attribute, instead of
820 abusing errno.
821
Tim Peters711bf302006-04-25 03:31:36 +0000822- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
823 a doctest to be skipped (the code is not run, and the expected output
824 or exception is ignored).
825
Nick Coghlanda2268f2006-04-24 04:37:15 +0000826- Fixed contextlib.nested to cope with exceptions being raised and
827 caught inside exit handlers.
828
Greg Wardab05edc2006-04-23 03:47:58 +0000829- Updated optparse module to Optik 1.5.1 (allow numeric constants in
830 hex, octal, or binary; add ``append_const`` action; keep going if
831 gettext cannot be imported; added ``OptionParser.destroy()`` method;
832 added ``epilog`` for better help generation).
833
Tim Peters21fbd572006-04-21 21:18:10 +0000834- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
835 called from a thread spawned as a side effect of importing a module.
836
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000837- The pydoc module now supports documenting packages contained in
838 .zip or .egg files.
839
840- The pkgutil module now has several new utility functions, such
841 as ``walk_packages()`` to support working with packages that are either
842 in the filesystem or zip files.
843
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000844- The mailbox module can now modify and delete messages from
845 mailboxes, in addition to simply reading them. Thanks to Gregory
846 K. Johnson for writing the code, and to the 2005 Google Summer of
847 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000848
Tim Petersc7605f22006-04-17 21:12:33 +0000849- The ``__del__`` method of class ``local`` in module ``_threading_local``
850 returned before accomplishing any of its intended cleanup.
851
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000852- Patch #790710: Add breakpoint command lists in pdb.
853
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000854- Patch #1063914: Add Tkinter.Misc.clipboard_get().

857
Anthony Baxtere29002c2006-04-12 12:07:31 +0000858- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
859 Windows. Bug #1469163.
860
Phillip J. Eby47032112006-04-11 01:07:43 +0000861- The warnings, linecache, inspect, traceback, site, and doctest modules
862 were updated to work correctly with modules imported from zipfiles or
863 via other PEP 302 __loader__ objects.
864
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000865- Patch #1467770: Reduce usage of subprocess._active to processes which
866 the application hasn't waited on.
867

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000885- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
886 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000887 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000888 CXX from --with-cxx-main, see description in README.
889

893
Tim Peters8931ff12006-05-13 23:28:20 +0000894- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
895 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,

Nick Coghlanda2268f2006-04-24 04:37:15 +0000901- test_contextlib now checks contextlib.nested can cope with exceptions
902 being raised and caught inside exit handlers.
903
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000904- test_cmd_line now checks operation of the -m and -c command switches
905
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000906- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
907 it separately and by hand. It also wasn't cleaning up its changes to
908 the current Decimal context.
909
Thomas Woutersabd08882006-04-26 15:53:30 +0000910- regrtest.py now has a -M option to run tests that test the new limits of
911 containers, on 64-bit architectures. Running these tests is only sensible
912 on 64-bit machines with more than two gigabytes of memory. The argument
913 passed is the maximum amount of memory for the tests to use.

923
Tim Petersb06d28c2006-05-12 01:57:59 +0000924- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
925
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000926- PEP 343: Added Context Types section to the library reference

941
Nick Coghlan43832302006-04-23 17:04:07 +0000942- PEP 338: -m command line switch now delegates to runpy.run_module
943 allowing it to support modules in packages and zipfiles
944
Martin v. Löwisc661b882006-04-20 04:54:23 +0000945- On Windows, .DLL is not an accepted file name extension for
946 extension modules anymore; extensions are only found if they
947 end in .PYD.
948
Martin v. Löwisea62d252006-04-03 10:56:49 +0000949- Bug #1421664: sys.stderr.encoding is now set to the same value as
950 sys.stdout.encoding.
951
Neal Norwitz92e212f2006-04-03 04:48:37 +0000952- __import__ accepts keyword arguments.
953
Georg Brandlccadf842006-03-31 18:54:53 +0000954- Patch #1460496: round() now accepts keyword arguments.
955
Anthony Baxter262c00a2006-03-30 10:53:17 +0000956- Fixed bug #1459029 - unicode reprs were double-escaped.
957
Hye-Shik Changd478f342006-03-23 12:32:36 +0000958- Patch #1396919: The system scope threads are reenabled on FreeBSD
959 5.4 and later versions.
960
Neal Norwitze98ccf62006-03-23 05:39:47 +0000961- Bug #1115379: Compiling a Unicode string with an encoding declaration
962 now gives a SyntaxError.
963
Georg Brandlabd1ff82006-03-18 07:59:59 +0000964- Previously, Python code had no easy way to access the contents of a
965 cell object. Now, a ``cell_contents`` attribute has been added
966 (closes patch #1170323).
967
Tim Peterscf79aac2006-03-16 01:14:46 +0000968- Patch #1123430: Python's small-object allocator now returns an arena to
969 the system ``free()`` when all memory within an arena becomes unused
970 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
971 freed. Some applications will see a drop in virtual memory size now,
972 especially long-running applications that, from time to time, temporarily
973 use a large number of small objects. Note that when Python returns an
974 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000975 platform C library will in turn return that memory to the operating system.
976 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000977 appears to be effective at least on Microsoft C and gcc-based systems.
978 Thanks to Evan Jones for hard work and patience.
979
Georg Brandl533ff6f2006-03-08 18:09:27 +0000980- Patch #1434038: property() now uses the getter's docstring if there is
981 no "doc" argument given. This makes it possible to legitimately use
982 property() as a decorator to produce a read-only property.
983
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000984- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
985 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
986 of requiring an int or long in slicing and a few other contexts, enabling
987 other objects (e.g. Numeric Python's integers) to be used as slice indices.
988
Neal Norwitz995acdf2006-03-07 05:01:00 +0000989- Fixed various bugs reported by Coverity's Prevent tool.
990
Brett Cannonbf364092006-03-01 04:25:17 +0000991- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
992 new exception base class, BaseException, which has a new message attribute.
993 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
994 Raising a string exception now raises a DeprecationWarning.
995
Thomas Woutersfb609f42006-02-28 16:37:25 +0000996- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
997 explicitly relative, using 'from .module import name' to mean 'from the same
998 package as this module is in. Imports without dots still default to the
999 old relative-then-absolute, unless 'from __future__ import
1000 absolute_import' is used.
1001
Brett Cannona7446e32006-02-27 23:39:10 +00001002- Properly check if 'warnings' raises an exception (usually when a filter set
1003 to "error" is triggered) when raising a warning for raising string
1004 exceptions.
1005
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001006- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001007 The name was removed from Include/code.h.
1008
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001009- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001010
Guido van Rossum1968ad32006-02-25 22:38:04 +00001011- Patch 1433928:
1012 - The copy module now "copies" function objects (as atomic objects).
1013 - dict.__getitem__ now looks for a __missing__ hook before raising
1014 KeyError.
1015
Tim Peters84ef21c2006-02-28 20:39:06 +00001016- PEP 343: with statement implemented. Needs ``from __future__ import
1017 with_statement``. Use of 'with' as a variable will generate a warning.
1018 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001019 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001020 The following objects have __context__ methods:
1021 - The built-in file type.
1022 - The thread.LockType type.
1023 - The following types defined by the threading module:
1024 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1025 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001026
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001027- Fix the encodings package codec search function to only search
1028 inside its own package. Fixes problem reported in patch #1433198.
1029
1030 Note: Codec packages should implement and register their own
1031 codec search function. PEP 100 has the details.
1032
Tim Peters9ea89d22006-06-04 03:26:02 +00001033- PEP 353: Using ``Py_ssize_t`` as the index type.
1034
1035- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1036 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1037 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1038 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1039 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001040
Neal Norwitzfc76d632006-01-10 06:03:13 +00001041- Patch #1400181, fix unicode string formatting to not use the locale.
1042 This is how string objects work. u'%f' could use , instead of .
1043 for the decimal point. Now both strings and unicode always use periods.
1044
Neal Norwitz671b9e32006-01-09 07:07:12 +00001045- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1046 configure would break checking curses.h.
1047
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001048- Bug #959576: The pwd module is now builtin. This allows Python to be
1049 built on UNIX platforms without $HOME set.
1050
Neal Norwitzc10978f2005-12-19 06:07:16 +00001051- Bug #1072182, fix some potential problems if characters are signed.
1052
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001053- Bug #889500, fix line number on SyntaxWarning for global declarations.
1054
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001055- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1056
Neal Norwitze7214a12005-12-18 05:03:17 +00001057- Support for converting hex strings to floats no longer works.
1058 This was not portable. float('0x3') now raises a ValueError.
1059
Barry Warsaw2a38a862005-12-18 01:27:35 +00001060- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001061 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001062 is now displayed in interactive prompt banner.
1063
Georg Brandlfa166682005-12-17 21:45:17 +00001064- Implementation of PEP 341 - Unification of try/except and try/finally.
1065 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001066 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001067
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001068- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1069 now encodes backslash correctly.
1070
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001071- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1072
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001073- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001074 and long longs.
1075
Neal Norwitz67715f02005-11-09 06:59:35 +00001076- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001077 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001078 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001079
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001080- Replaced most Unicode charmap codecs with new ones using the
1081 new Unicode translate string feature in the builtin charmap
1082 codec; the codecs were created from the mapping tables available
1083 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1084 encodings now include a mapping for the Apple logo)
1085
Tim Peterse3547fd2005-12-16 23:13:57 +00001086- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001087
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001088- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001089
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001090- A new AST parser implementation was completed. The abstract
1091 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001092 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001093
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001094- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001095 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1096
Neal Norwitz708e51a2005-10-03 04:48:15 +00001097- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1098
Neal Norwitz11bd1192005-10-03 00:54:56 +00001099- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1100 Provide a warning when a directory is passed on the command line.
1101
Neal Norwitz40d37812005-10-02 01:48:49 +00001102- Fix segfault with invalid coding.
1103
1104- SF bug #772896: unknown encoding results in MemoryError.
1105
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001106- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001107 supported a __len__() method which evaluated to False when the iterator
1108 was empty.
1109
Guido van Rossum630db602005-09-20 18:49:54 +00001110- On 64-bit platforms, when __len__() returns a value that cannot be
1111 represented as a C int, raise OverflowError.
1112
Skip Montanarof8948ca2005-09-19 03:54:46 +00001113- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001114 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001115
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001116- SF bug #893549: parsing keyword arguments was broken with a few format
1117 codes.
1118
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001119- Changes donated by Elemental Security to make it work on AIX 5.3
1120 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1121 bug #105470: test_pwd fails on 64bit system (Opteron).
1122
Guido van Rossum539c6622005-09-14 17:49:54 +00001123- Changes donated by Elemental Security to make it work on HP-UX 11 on
1124 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1125
Georg Brandl4550b8d2005-08-26 06:43:52 +00001126- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001127 (fixes bug #1119418).
1128
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001129- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1130
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001131- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1132 exceptions that cause a function to exit.
1133
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001134- The implementation of set() and frozenset() was revised to use its
1135 own internal data structure. Memory consumption is reduced by 1/3
1136 and there are modest speed-ups as well. The API is unchanged.
1137
Tim Petersde7990b2005-07-17 23:45:23 +00001138- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1139
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001140- SF bug #1229429: PyObject_CallMethod failed to decrement some
1141 reference counts in some error exit cases.
1142
Tim Petersecc6e6a2005-07-10 22:30:55 +00001143- SF bug #1185883: Python's small-object memory allocator took over
1144 a block managed by the platform C library whenever a realloc specified
1145 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001146 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001147 portable way to copy data from the C-managed block into Python's
1148 small-object space without risking a memory fault. Python's small-object
1149 realloc now leaves such blocks under the control of the platform C
1150 realloc.
1151
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001152- SF bug #1232517: An overflow error was not detected properly when
1153 attempting to convert a large float to an int in os.utime().
1154
Raymond Hettinger3296e692005-06-29 23:29:56 +00001155- SF bug #1224347: hex longs now print with lowercase letters just
1156 like their int counterparts.
1157
Michael W. Hudson188d4362005-06-20 16:52:57 +00001158- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1159 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1160 interpreter states; back out that fix and do a better job (see
1161 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1162 for a longer write-up of the problem).
1163
Michael W. Hudsondf888462005-06-03 14:41:55 +00001164- SF patch #1180995: marshal now uses a binary format by default when
1165 serializing floats.
1166
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001167- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1168 the routines that promise to produce IEEE 754 binary representations
1169 of floats now simply copy bytes around.
1170
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001171- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1172 278.
1173
Brett Cannonc3647ac2005-04-26 03:45:26 +00001174- patch #1109424: int, long, float, complex, and unicode now check for the
1175 proper magic slot for type conversions when subclassed. Previously the
1176 magic slot was ignored during conversion. Semantics now match the way
1177 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001178 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001179 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001180 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001181
Barry Warsawc8d907c2005-04-19 23:43:40 +00001182- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1183 NULL, now raise an AttributeError when attempting to set or delete the
1184 attribute. Previously a TypeError was raised, but this was inconsistent
1185 with the equivalent pure-Python implementation.
1186
Michael W. Hudson774479c2005-04-18 08:46:17 +00001187- It is now safe to call PyGILState_Release() before
1188 PyEval_InitThreads() (note that if there is reason to believe there
1189 are multiple threads around you still must call PyEval_InitThreads()
1190 before using the Python API; this fix is for extension modules that
1191 have no way of knowing if Python is multi-threaded yet).
1192
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001193- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1194 disabled caused a crash.
1195
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001196- Bug #1165306: instancemethod_new allowed the creation of a method
1197 with im_class == im_self == NULL, which caused a crash when called.
1198
Tim Petersecc6e6a2005-07-10 22:30:55 +00001199- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001200 fixes the crash seen in bug #1165761
1201
Raymond Hettinger96229b12005-03-11 06:49:40 +00001202- Added two new builtins, any() and all().
1203
Brett Cannon409d8f22005-03-05 06:47:57 +00001204- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001205 (e.g., ``class C(): pass`` is no longer a syntax error).
1206 Patch #1176012 added support to the 'parser' module and 'compiler' package
1207 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001208
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001209- Patch #1115086: Support PY_LONGLONG in structmember.
1210
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001211- Bug #1155938: new style classes did not check that __init__() was
1212 returning None.

1242 calling __str__ on the argument returns a unicode instance.
1243
Tim Petersf4e69282006-02-27 17:15:31 +00001244- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1245 current thread state when the auto-GIL-state machinery knows about
1246 it (since the thread state is being deleted, continuing to remember it
1247 can't help, but can hurt if another thread happens to get created with
1248 the same thread id).

Nick Coghlan43832302006-04-23 17:04:07 +00001444- PEP 338: new module runpy defines a run_module function to support
1445 executing modules which provide access to source code or a code object
1446 via the PEP 302 import mechanisms.

1456 in attribute values.
1457
Anthony Baxterc51ee692006-04-01 00:57:31 +00001458- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001459 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001460 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001461 module will not be built.

Tim Petersc17976e2006-04-01 00:26:53 +00001463- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1464 aren't officially supported here, and trying to use them will probably

1486
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001487- email 4.0 package now integrated. This is largely the same as the email 3.0
1488 package that was included in Python 2.3, except that PEP 8 module names are
1489 now used (e.g. mail.message instead of email.Message). The MIME classes
1490 have been moved to a subpackage (e.g. email.mime.text instead of
1491 email.MIMEText). The old names are still supported for now. Several
1492 deprecated Message methods have been removed and lots of bugs have been
1493 fixed. More details can be found in the email package documentation.

1496 (a subclass of tuple) that provides incremental decoders and encoders
1497 (a way to use stateful codecs without the stream API). Python functions
1498 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1499 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1500 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001501
Walter Dörwald067db482006-03-15 22:17:27 +00001502- Patch #1359365: Calling next() on a closed StringIO.String object raises
1503 a ValueError instead of a StopIteration now (like file and cString.String do).
1504 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1505 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00001579 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1580 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1581 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1582 Ronald L. Rivest offered this advice for Python:
1583
1584 "The consensus of researchers in this area (at least as
1585 expressed at the NIST Hash Function Workshop 10/31/05),
1586 is that SHA-256 is a good choice for the time being, but
1587 that research should continue, and other alternatives may
1588 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001589

1742
Martin v. Löwis4afe1542005-03-01 08:09:28 +00001743- Patch #1121234: Properly cleanup _exit and tkerror commands.
1744
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001745- Patch #1049151: xdrlib now unpacks booleans as True or False.
1746
Raymond Hettingerbab41432005-02-05 01:31:19 +00001747- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1748
Guido van Rossumd0641422005-02-03 15:01:24 +00001749- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1750 disables recursive traversal through instance attributes, which can
1751 be exploited in various ways.
1752
Tim Peterse3547fd2005-12-16 23:13:57 +00001753- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001754 flags on the HTTP listening socket.
1755
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001756- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1757 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1758
Fred Drakefbdeaad2006-07-29 16:56:15 +00001759- Patches #893642, #1039083: add allow_none, encoding arguments to
1760 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001761

1763
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001764- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1765
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001766- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1767
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001768- Enhancements to the csv module:
1769
1770 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001771 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001772 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001773 + Dialect parameter parsing has been re-implemented to improve error
1774 reporting.
1775 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1776 dictates.
1777 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001778 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001779 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001780 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1781 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001782 + reader now allows \r characters to be quoted (previously it only allowed
1783 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001784 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001785 + Dialect classes passed to the module are no longer instantiated by
1786 the module before being parsed (the former validation scheme required
1787 this, but the mechanism was unreliable).
1788 + The dialect registry now contains instances of the internal
1789 C-coded dialect type, rather than references to python objects.
1790 + the internal c-coded dialect type is now immutable.
1791 + register_dialect now accepts the same keyword dialect specifications
1792 as the reader and writer, allowing the user to register dialects
1793 without first creating a dialect class.
1794 + a configurable limit to the size of parsed fields has been added -
1795 previously, an unmatched quote character could result in the entire
1796 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001797 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001798 the parser field size limit (returning the former limit). The initial
1799 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001800 + A line_num attribute has been added to the reader object, which tracks
1801 the number of lines read from the source iterator. This is not
1802 the same as the number of records returned, as records can span
1803 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001804 + reader and writer objects were not being registered with the cyclic-GC.
1805 This has been fixed.
1806
Brett Cannone6539c42005-01-08 02:43:53 +00001807- _DummyThread objects in the threading module now delete self.__block that is
1808 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1809 lock primitives tend to be limited in number and thus should not be wasted on
1810 a _DummyThread object. Fixes bug #1089632.
1811
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001812- The imghdr module now detects Exif files.
1813
Raymond Hettinger6065d322004-12-20 23:51:53 +00001814- StringIO.truncate() now correctly adjusts the size attribute.
1815 (Bug #951915).
1816
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001817- locale.py now uses an updated locale alias table (built using
1818 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1819 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001820 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001821
Raymond Hettinger3557f422004-12-07 12:02:02 +00001822- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1823
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001824- the pickle module no longer accepts the deprecated None option in the
1825 args tuple returned by __reduce__().
1826
Brett Cannon84667c02004-12-07 03:25:18 +00001827- optparse now optionally imports gettext. This allows its use in setup.py.
1828
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001829- the pickle module no longer uses the deprecated bin parameter.
1830
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001831- the shelve module no longer uses the deprecated binary parameter.
1832
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001833- the pstats module no longer uses the deprecated ignore() method.
1834
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001835- the filecmp module no longer uses the deprecated use_statcache argument.
1836
Raymond Hettinger664347b2004-12-04 21:21:53 +00001837- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1838 extended or overridden by subclasses. Formerly, the subclassed method would
1839 be ignored by the rest of the module. (Bug #1078905).
1840
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001841- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001842 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001843
Walter Dörwald36733692004-12-22 12:50:50 +00001844- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1845 once when a size argument is given. This prevents a buffer overflow in the
1846 tokenizer with very long source lines.
1847
Barry Warsaw538561e2006-01-01 21:48:54 +00001848- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1849 immediately after creating the object, without any intervening
1850 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001851
Skip Montanaro05885812005-01-16 20:48:27 +00001852- The reconvert.quote function can now emit triple-quoted strings. The
1853 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001854
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001855- ``UserString.MutableString`` now supports negative indices in
1856 ``__setitem__`` and ``__delitem__``
1857
Greg Ward40407942005-03-05 02:53:17 +00001858- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1859 correctly.
1860
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001861- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1862 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1863 character even if the user has passed a size parameter to get a proper
1864 line ending. Remove the special handling of a "\r\n" that has been split
1865 between two lines.
1866
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001867- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1868 about illegal code points. The codec now supports PEP 293 style error
1869 handlers.
1870
Walter Dörwald78a78b02005-09-01 12:04:29 +00001871- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001872 from the input stream, so that the output is a byte string in the correct
1873 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001874
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001875- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1876 considering it exactly like a '*'.
1877
Walter Dörwald007f8df2005-10-09 19:42:27 +00001878- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1879 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001880
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001881- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1882
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001883- Patch #1413711: Certain patterns of differences were making difflib
1884 touch the recursion limit.
1885
Walter Dörwald58917a62006-03-31 15:26:22 +00001886- Bug #947906: An object oriented interface has been added to the calendar
1887 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001888 called as a script (e.g. via ``python -mcalendar``). Localized month and
1889 weekday names can be ouput (even if an exotic encoding is used) using
1890 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001891
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001892Build
1893-----
1894
Neal Norwitz602d3392006-03-31 08:21:40 +00001895- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1896 by using -mieee gcc option.
1897
Martin v. Löwis86d66262006-02-17 08:40:11 +00001898- Patch #1432345: Make python compile on DragonFly.
1899
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001900- Build support for Win64-AMD64 was added.
1901
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001902- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1903
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001904- Patch #881820: look for openpty and forkpty also in libbsd.
1905
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001906- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1907 The zlib module is now builtin on Windows.
1908
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001909- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1910
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001911- Bug #1189330: configure did not correctly determine the necessary
1912 value of LINKCC if python was built with GCC 4.0.
1913
Trent Mick8321b422005-07-26 02:29:21 +00001914- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1915 vulnerability in zlib 1.2.1 and 1.2.2.
1916
Brett Cannon08cd5982005-04-24 22:26:38 +00001917- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1918 flags that change binary compatibility. Changes were also made to
1919 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001920 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001921
Bob Ippolitoed233462005-03-29 13:47:59 +00001922- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1923 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1924 no longer exists). This configure patch makes things right.
1925
Martin v. Löwise2713be2005-03-08 15:03:08 +00001926- Bug #1158607: Build with --disable-unicode again.
1927
Brett Cannon46d96232005-02-16 00:07:19 +00001928- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1929 defined. Discovered as a result of not being able to build on OS X.
1930
Brett Cannon516592f2004-12-07 00:42:59 +00001931- setup.py now uses the directories specified in LDFLAGS using the -L option
1932 and in CPPFLAGS using the -I option for adding library and include
1933 directories, respectively, for compiling extension modules against. This has
1934 led to the core being compiled using the values in CPPFLAGS. It also removes
1935 the need for the special-casing of both DarwinPorts and Fink for darwin since
1936 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1937 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1938 Fink, ``-I/opt/local/include`` for DarwinPorts).
1939
Brett Cannon43802422005-02-10 20:48:03 +00001940- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1941 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1942 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1943 Closes bug #1096244. Thanks Gregory Bond.
1944
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001945C API
1946-----
1947
Tim Petersc9d78aa2006-03-26 23:27:58 +00001948- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1949 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1950 is obtained via the ``PyObject_`` family, it must be released via the
1951 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1952 always been officially true, but when Python's small-object allocator was
1953 introduced, an attempt was made to cater to a few extension modules
1954 discovered at the time that obtained memory via ``PyObject_New`` but
1955 released it via ``PyMem_DEL``. It's years later, and if such code still
1956 exists it will fail now (probably with segfaults, but calling wrong
1957 low-level memory management functions can yield many symptoms).
1958
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001959- Added a C API for set and frozenset objects.
1960
Raymond Hettinger66517482004-12-03 11:45:13 +00001961- Removed PyRange_New().
1962
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001963- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1964 mapping argument now. This string is used as a mapping table. Byte values
1965 greater than the length of the string and 0xFFFE are treated as undefined
1966 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001973
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001974- Patch #1276356: New resource "urlfetch" is implemented. This enables
