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

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().

Fred Drake53912162006-07-29 13:22:49 +000083What's New in Python 2.5 beta 3?
84================================
Neal Norwitza1f10902006-07-12 07:28:29 +000085
Anthony Baxter5d32a9f2006-08-02 07:43:09 +000086*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +000087
88Core and builtins
89-----------------
90
Neal Norwitzc5e060d2006-08-02 06:14:22 +000091- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t, it previously
92 returned a long (see PEP 353).
93
Neal Norwitzf71ec5a2006-07-30 06:57:04 +000094- Bug #1515471: string.replace() accepts character buffers again.
95
Neal Norwitz07aadb12006-07-30 06:55:48 +000096- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
97 This provides the proper warning for struct.pack().
98 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
99
Neal Norwitz0d62a062006-07-30 06:53:31 +0000100- Patch #1531113: Fix augmented assignment with yield expressions.
101 Also fix a SystemError when trying to assign to yield expressions.
102
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000103- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
104 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
105 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
106 excessive filesystem operations during imports.
107
Tim Petersbc24eee2006-07-27 01:14:53 +0000108- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
109 operations on signed longs that are formally undefined by C.
110 Unfortunately, at least one compiler now cares about that, so complicated
111 the code to make that compiler happy again.
112
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000113- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
114
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000115- Patch #1232023: Stop including current directory in search
116 path on Windows.
117
Neal Norwitze1fdb322006-07-21 05:32:28 +0000118- Fix some potential crashes found with failmalloc.
119
Neal Norwitze7563102006-07-17 01:00:16 +0000120- Fix warnings reported by Klocwork's static analysis tool.
121
Neal Norwitz84be93b2006-07-16 01:50:38 +0000122- Bug #1512814, Fix incorrect lineno's when code within a function
123 had more than 255 blank lines.
124
Georg Brandl9dceedb2006-07-12 15:31:17 +0000125- Patch #1521179: Python now accepts the standard options ``--help`` and
126 ``--version`` as well as ``/?`` on Windows.
127
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000128- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000129 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000130 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000131
Tim Peters112aad32006-07-19 00:03:19 +0000132- Bug #1524317: Compiling Python ``--without-threads`` failed.
133 The Python core compiles again then, and, in a build without threads, the
134 new ``sys._current_frames()`` returns a dictionary with one entry,
135 mapping the faux "thread id" 0 to the current frame.
136
Ronald Oussoren3075e162006-07-25 20:28:55 +0000137- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000138
Ronald Oussoren3075e162006-07-25 20:28:55 +0000139
Neal Norwitza1f10902006-07-12 07:28:29 +0000140Library
141-------
142
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000143- Correction of patch #1455898: In the mbcs decoder, set final=False
144 for stream decoder, but final=True for the decode function.
145
Georg Brandl07fec3a2006-08-01 18:49:24 +0000146- os.urandom no longer masks unrelated exceptions like SystemExit or
147 KeyboardInterrupt.
148
Martin v. Löwis4e678382006-07-30 13:00:31 +0000149- Bug #1525866: Don't copy directory stat times in
150 shutil.copytree on Windows
151
Georg Brandle34ac7c2006-07-30 11:07:23 +0000152- Bug #1002398: The documentation for os.path.sameopenfile now correctly
153 refers to file descriptors, not file objects.
154
Fred Drakefbdeaad2006-07-29 16:56:15 +0000155- Rename of the xml package to xmlcore, and the import hackery done to
156 make it appear at both names, has been removed. Bug #1511497,
157 #1513611, and probably others.
158
Georg Brandledd9b0d2006-07-29 09:33:26 +0000159- Bug #1441397: The compiler module now recognizes module and function
160 docstrings correctly as it did in Python 2.4.
161
Tim Peters6f681472006-07-27 23:44:37 +0000162- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
163 lost that tests are sorted by name before being run. This rarely
164 matters for well-written tests, but can create baffling symptoms if
165 side effects from one test to the next affect outcomes. ``DocTestFinder``
166 has been changed to sort the list of tests it returns.
167
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000168- The distutils version has been changed to 2.5.0, and are now kept
169 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000170
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000171- Bug #978833: Really close underlying socket in _socketobject.close.
172
Georg Brandl0619a322006-07-26 07:40:17 +0000173- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
174 with title().
175
Georg Brandlcf0c1722006-07-26 07:23:32 +0000176- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
177 to recursive calls and call it with the failing package name.
178
Martin v. Löwis0b483032006-07-25 09:53:12 +0000179- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
180
Georg Brandlc13c34c2006-07-24 14:09:56 +0000181- Patch #1515343: Fix printing of deprecated string exceptions with a
182 value in the traceback module.
183
Greg Ward48fae7a2006-07-23 16:05:51 +0000184- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
185
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000186- Patch #1524429: Use repr() instead of backticks in Tkinter again.
187
Brett Cannoncaebe222006-07-18 04:41:36 +0000188- Bug #1520914: Change time.strftime() to accept a zero for any position in its
189 argument tuple. For arguments where zero is illegal, the value is forced to
190 the minimum value that is correct. This is to support an undocumented but
191 common way people used to fill in inconsequential information in the time
192 tuple pre-2.4.
193
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000194- Patch #1220874: Update the binhex module for Mach-O.
195
Barry Warsawb110bad2006-07-21 14:51:07 +0000196- The email package has improved RFC 2231 support, specifically for
197 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
198 (name*0=<blah>) parameter continuations. This may change the types of
199 values returned from email.message.Message.get_param() and friends.
200 Specifically in some cases where non-encoded continuations were used,
201 get_param() used to return a 3-tuple of (None, None, string) whereas now it
202 will just return the string (since non-encoded continuations don't have
203 charset and language parts).
204
205 Also, whereas % values were decoded in all parameter continuations, they are
206 now only decoded in encoded parameter parts.
207
Ronald Oussoren3075e162006-07-25 20:28:55 +0000208- Bug #1517990: IDLE keybindings on MacOS X now work correctly
209
210- Bug #1517996: IDLE now longer shows the default Tk menu when a
211 path browser, class browser or debugger is the frontmost window on MacOS X
212
Barry Warsaw00decd72006-07-27 23:43:15 +0000213- Patch #1520294: Support for getset and member descriptors in types.py,
214 inspect.py, and pydoc.py. Specifically, this allows for querying the type
215 of an object against these built-in types and more importantly, for getting
216 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +0000219Extension Modules
220-----------------
221
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000222- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
223 a socket operation on a socket with a timeout, the exception will be
224 caught correctly. Previously, the exception was not caught.
225
Thomas Heller1393d6a2006-07-28 21:43:20 +0000226- Patch #1529514: The _ctypes extension is now compiled on more
227 openbsd target platforms.
228
Tim Peters9cab5932006-07-28 00:30:00 +0000229- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
230 a memory leak, affecting pickles and deep copies.
231
Tim Petersbc24eee2006-07-27 01:14:53 +0000232- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000233 Paul Eggert.
234
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000235- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
236
Thomas Hellerce049a02006-07-14 17:51:14 +0000237- Patch #1521817: Index range checking on ctypes arrays containing
238 exactly one element enabled again. This allows iterating over these
239 arrays, without the need to check the array size before.
240
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000241- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000242 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000243 /dev/null in certain cases; this is now fixed.
244
Thomas Heller47d7a062006-07-12 08:43:47 +0000245- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
246 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000247
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000248- Because of a misspelled preprocessor symbol, ctypes was always
249 compiled without thread support; this is now fixed.
250
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000251- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
252 methods now allow their database parameter to be None as the
253 sleepycat API allows.
254
Matt Flemingec926502006-07-28 11:27:27 +0000255- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
256 bluetooth API compared with Linux and FreeBSD.
257
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000258Tests
259-----
260
261- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
262 how long the test file should take to play. Now accepts taking 2.93 secs
263 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
264
Georg Brandl4793aa32006-07-28 18:31:39 +0000265- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
266 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
267 run via ``regrtest.py``. Now they do.

273
Ronald Oussoren26cad082006-08-01 21:00:57 +0000274Mac
275---
276
277- PythonLauncher now works correctly when the path to the script contains
278 characters that are treated specially by the shell (such as quotes).
279
280- Bug #1527397: PythonLauncher now launches scripts with the working directory
281 set to the directory that contains the script instead of the user home
282 directory. That latter was an implementation accident and not what users
283 expect.

293
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000294- Bug #1441486: The literal representation of -(sys.maxint - 1)
295 again evaluates to a int object, not a long.
296
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000297- Bug #1501934: The scope of global variables that are locally assigned
298 using augmented assignment is now correctly determined.
299
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000300- Bug #927248: Recursive method-wrapper objects can now safely
301 be released.
302
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000303- Bug #1417699: Reject locale-specific decimal point in float()
304 and atof().
305
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000306- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
307 omit a default "error" argument for NULL pointer. This allows
308 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000309
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000310- Bug #1519018: 'as' is now validated properly in import statements.
311
Neal Norwitz28746ab2006-07-09 22:14:42 +0000312- On 64 bit systems, int literals that use less than 64 bits are
313 now ints rather than longs.
314
Neal Norwitzed657552006-07-10 00:04:44 +0000315- Bug #1512814, Fix incorrect lineno's when code at module scope
316 started after line 256.
317
Tim Peters32a83612006-07-10 21:08:24 +0000318- New function ``sys._current_frames()`` returns a dict mapping thread
319 id to topmost thread stack frame. This is for expert use, and is
320 especially useful for debugging application deadlocks. The functionality
321 was previously available in Fazal Majid's ``threadframe`` extension
322 module, but it wasn't possible to do this in a wholly threadsafe way from
323 an extension.

340
Thomas Woutersadd19112006-07-05 11:03:49 +0000341- string.Template() now correctly handles tuple-values. Previously,
342 multi-value tuples would raise an exception and single-value tuples would
343 be treated as the value they contain, instead.
344
Martin v. Löwisede77f52006-07-03 13:01:35 +0000345- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

361 socket again, which then gets closed as it becomes unreferenced.
362
Fred Drake10497c82006-06-29 02:57:48 +0000363- Bug #1504333: Make sgmllib support angle brackets in quoted

370
Brett Cannon53ab5b72006-06-22 16:49:14 +0000371- Bug #1510580: The 'warnings' module improperly required that a Warning
372 category be either a types.ClassType and a subclass of Warning. The proper
373 check is just that it is a subclass with Warning as the documentation states.
374
Georg Brandlad29e632006-06-21 17:45:17 +0000375- The compiler module now correctly compiles the new try-except-finally
376 statement (bug #1509132).
377
Neal Norwitz60373cd2006-06-22 06:30:50 +0000378- The wsgiref package is now installed properly on Unix.
379
Vinay Sajip28e57612006-07-01 10:45:20 +0000380- A bug was fixed in logging.config.fileConfig() which caused a crash on
381 shutdown when fileConfig() was called multiple times.
382
Gerhard Häring762fbd32006-07-02 17:48:30 +0000383- The sqlite3 module did cut off data from the SQLite database at the first
384 null character before sending it to a custom converter. This has been fixed
385 now.

388-----------------
389
Tim Peters112aad32006-07-19 00:03:19 +0000390- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
391 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
392 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000393
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000394- Assigning None to pointer type fields in ctypes structures possible
395 overwrote the wrong fields, this is fixed now.
396
397- Fixed a segfault in _ctypes when ctypes.wintypes were imported
398 on non-Windows platforms.
399
400- Bug #1518190: The ctypes.c_void_p constructor now accepts any
401 integer or long, without range checking.
402
403- Patch #1517790: It is now possible to use custom objects in the ctypes
404 foreign function argtypes sequence as long as they provide a from_param
405 method, no longer is it required that the object is a ctypes type.
406
407- The '_ctypes' extension module now works when Python is configured
408 with the --without-threads option.
409
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000410- Bug #1513646: os.access on Windows now correctly determines write
411 access, again.
412
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000413- Bug #1512695: cPickle.loads could crash if it was interrupted with
414 a KeyboardInterrupt.
415
Neal Norwitza12aa882006-07-06 06:45:08 +0000416- Bug #1296433: parsing XML with a non-default encoding and
417 a CharacterDataHandler could crash the interpreter in pyexpat.

423
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000424- Automate Windows build process for the Win64 SSL module.
425
Tim Peters32a83612006-07-10 21:08:24 +0000426- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000427 Previously, the slight difference could cause compilation errors of the
428 'zlib' module on systems with more than one version of zlib.
429
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000430- The MSI compileall step was fixed to also support a TARGETDIR
431 with spaces in it.

461Core and builtins
462-----------------
463
Georg Brandla56b9152006-06-19 06:35:54 +0000464- Patch #1507676: Error messages returned by invalid abstract object operations
465 (such as iterating over an integer) have been improved and now include the
466 type of the offending object to help with debugging.
467
Brett Cannonea3912b2006-06-13 21:46:41 +0000468- Bug #992017: A classic class that defined a __coerce__() method that returned
469 its arguments swapped would infinitely recurse and segfault the interpreter.
470
Neal Norwitz909eb122006-06-12 02:13:21 +0000471- Fix the socket tests so they can be run concurrently.
472
Neal Norwitzb9845e72006-06-12 02:11:18 +0000473- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000474 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000475
Brett Cannon22565aa2006-06-09 22:31:23 +0000476- Bug #532646: object.__call__() will continue looking for the __call__
477 attribute on objects until one without one is found. This leads to recursion
478 when you take a class and set its __call__ attribute to an instance of the
479 class. Originally fixed for classic classes, but this fix is for new-style.
480 Removes the infinite_rec_3 crasher.
481
Georg Brandl24250812006-06-09 18:45:48 +0000482- The string and unicode methods startswith() and endswith() now accept
483 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
484
Brett Cannonde3b0522006-06-08 17:00:45 +0000485- Buffer objects, at the C level, never used the char buffer
486 implementation even when the char buffer for the wrapped object was
487 explicitly requested (originally returned the read or write buffer).
488 Now a TypeError is raised if the char buffer is not present but is
489 requested.
490
Georg Brandlddbaa662006-06-04 21:56:52 +0000491- Patch #1346214: Statements like "if 0: suite" are now again optimized
492 away like they were in Python 2.4.
493
Georg Brandlb7c8f542006-05-27 12:30:25 +0000494- Builtin exceptions are now full-blown new-style classes instead of
495 instances pretending to be classes, which speeds up exception handling
496 by about 80% in comparison to 2.5a2.
497
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000498- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
499 Unicode 4.1.
500
Georg Brandlf4ef1162006-05-26 18:03:31 +0000501- Patch #921466: sys.path_importer_cache is now used to cache valid and
502 invalid file paths for the built-in import machinery which leads to
503 fewer open calls on startup.
504
Tim Peters696cf432006-05-24 21:10:40 +0000505- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
506 of-2 bases. The largest speedup is for inputs with about 1000 decimal
507 digits. Conversion from non-power-of-2 bases remains quadratic-time in
508 the number of input digits (it was and remains linear-time for bases
509 2, 4, 8, 16 and 32).
510
Tim Petersb713ec22006-05-23 18:45:30 +0000511- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
512 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
513 an integer close to ``sys.maxint``. This was repaired by patch
514 #1335972, which also gives a nice speedup.
515
Richard Jonescebbefc2006-05-23 18:28:17 +0000516- Patch #1337051: reduced size of frame objects.
517
518- PyErr_NewException now accepts a tuple of base classes as its
519 "base" parameter.
520
Richard Jones7c88dcc2006-05-23 10:37:38 +0000521- Patch #876206: function call speedup by retaining allocated frame
522 objects.
523
Georg Brandl7b90e162006-05-18 07:01:27 +0000524- Bug #1462152: file() now checks more thoroughly for invalid mode
525 strings and removes a possible "U" before passing the mode to the
526 C library function.
527
Neal Norwitz1004a532006-05-15 07:17:23 +0000528- Patch #1488312, Fix memory alignment problem on SPARC in unicode
529
Neal Norwitz373f0a72006-05-15 07:04:36 +0000530- Bug #1487966: Fix SystemError with conditional expression in assignment
531
Martin v. Löwis879768d2006-05-11 13:28:43 +0000532- WindowsError now has two error code attributes: errno, which carries
533 the error values from errno.h, and winerror, which carries the error
534 values from winerror.h. Previous versions put the winerror.h values
535 (from GetLastError()) into the errno attribute.
536
Martin v. Löwis77736712006-05-04 05:51:03 +0000537- Patch #1475845: Raise IndentationError for unexpected indent.
538
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000539- Patch #1479181: split open() and file() from being aliases for each other.
540
Tim Peters44bd9862006-06-01 13:49:23 +0000541- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
542 methods were always silently ignored by dictionaries when comparing keys.
543 They are now passed through (except when using the C API function
544 ``PyDict_GetItem()``, whose semantics did not change).
545
546- Bug #1456209: In some obscure cases it was possible for a class with a
547 custom ``__eq__()`` method to confuse dict internals when class instances
548 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
549 No, you don't have any code that did this ;-)

557
Brett Cannon6ee7d012006-06-08 16:23:04 +0000558- Change binascii.hexlify to accept a read-only buffer instead of only a char
559 buffer and actually follow its documentation.
560
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000561- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
562
Nick Coghlanc649ec52006-05-29 12:43:05 +0000563- Patch #1478788 (modified version): The functional extension module has
564 been renamed to _functools and a functools Python wrapper module added.
565 This provides a home for additional function related utilities that are
566 not specifically about functional programming. See PEP 309.
567
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000568- Patch #1493701: performance enhancements for struct module.

577
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000578- On Win32, os.listdir now supports arbitrarily-long Unicode path names
579 (up to the system limit of 32K characters).
580
581- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
582 As a result, these functions now raise WindowsError instead of OSError.
583
Tim Peters7a822da2006-05-25 21:50:17 +0000584- ``time.clock()`` on Win64 should use the high-performance Windows
585 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
586 Windows platforms).
587
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000588- Calling Tk_Init twice is refused if the first call failed as that
589 may deadlock.
590
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000591- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
592 accept it without potentially using an uninitialized pointer.
593
594- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
595 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Vinay Sajip28e57612006-07-01 10:45:20 +0000613 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000614 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
615 database calls that would previously deadlock. [SF python bug #775414]

Martin v. Löwis3798da02006-06-17 18:44:27 +0000628- Patch #812986: Update turtle output even if not tracing.
629
Vinay Sajip28e57612006-07-01 10:45:20 +0000630- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000631 Tkinter.BaseWidget.
632
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000633- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
634

636 classes.
637
Georg Brandl83cc0d02006-06-14 08:50:03 +0000638- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
639 mime.types file for determining MIME types.
640
Georg Brandl2605ca82006-06-14 06:08:31 +0000641- Bug #1339007: Shelf objects now don't raise an exception in their
642 __del__ method when initialization failed.
643
Martin v. Löwisd8251432006-06-14 05:21:04 +0000644- Patch #1455898: The MBCS codec now supports the incremental mode for
645 double-byte encodings.
646
Tim Peters43898b42006-06-14 04:09:25 +0000647- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
648 guarantee that adjacent triples in the return list always describe
649 non-adjacent blocks. Previously, a pair of matching blocks could end
650 up being described by multiple adjacent triples that formed a partition
651 of the matching pair.
652
Greg Ward0e0c9f42006-06-11 16:24:11 +0000653- Bug #1498146: fix optparse to handle Unicode strings in option help,
654 description, and epilog.
655
Greg Wardd1c797e2006-06-11 14:42:41 +0000656- Bug #1366250: minor optparse documentation error.
657
Greg Ward7f547402006-06-11 00:40:49 +0000658- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
659 clarify docs.
660
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000661- The wsgiref package has been added to the standard library.
662
Nick Coghlan676725d2006-06-08 13:54:49 +0000663- The functions update_wrapper() and wraps() have been added to the functools
664 module. These make it easier to copy relevant metadata from the original
665 function when writing wrapper functions.
666
Tim Petersd6a9eef2006-06-05 01:48:21 +0000667- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
668 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000669
Martin v. Löwis3f767792006-06-04 19:36:28 +0000670- Patch #1359618: Speed up charmap encoder by using a trie structure
671 for lookup.
672
Tim Petersd609b1a2006-06-02 23:22:51 +0000673- The functions in the ``pprint`` module now sort dictionaries by key
674 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
675 if and only if its display required more than one line, although that
676 wasn't documented. The new behavior increases predictability; e.g.,
677 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
678
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000679- Patch #1497027: try HTTP digest auth before basic auth in urllib2
680 (thanks for J. J. Lee).
681
Georg Brandl2b330372006-05-28 20:23:12 +0000682- Patch #1496206: improve urllib2 handling of passwords with respect to
683 default HTTP and HTTPS ports.
684
George Yoshidaf3c65de2006-05-28 16:39:09 +0000685- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
686
Bob Ippolito7298f272006-05-23 18:43:47 +0000687- Patch #1281707: speed up gzip.readline.
688
Georg Brandlb89316f2006-05-17 15:51:16 +0000689- Patch #1180296: Two new functions were added to the locale module:
690 format_string() to get the effect of "format % items" but locale-aware,
691 and currency() to format a monetary number with currency sign.
692
Georg Brandle3a25832006-05-17 14:56:04 +0000693- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
694 and several features added, such as speed and geometry control.
695
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000696- Patch #1488881: add support for external file objects in bz2 compressed
697 tarfiles.
698
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000699- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
700 stdout arguments, making it possible to redirect input and output
701 for remote debugging.
702
703- Patch #1484695: Update the tarfile module to version 0.8. This fixes
704 a couple of issues, notably handling of long file names using the
705 GNU LONGNAME extension.
706
707- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
708 new flag when ``name`` is already the name of an option flag.
709
710- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
711 package.
712
713- Patch #1472854: make the rlcompleter.Completer class usable on non-
714 UNIX platforms.
715
716- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
717
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000718- Bug #1472827: correctly escape newlines and tabs in attribute values in
719 the saxutils.XMLGenerator class.

748
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000749What's New in Python 2.5 alpha 2?
750=================================
751
752*Release date: 27-APR-2006*
753
754Core and builtins
755-----------------
756
Thomas Heller1b046642006-04-18 18:51:06 +0000757- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
758 by converting these apis from macros into exported functions again:
759
760 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
761 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
762 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
763 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
764 PyRun_String Py_CompileString
765
Martin v. Löwis45294a92006-04-18 06:24:08 +0000766- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
767
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000768- All uses of PyStructSequence_InitType have been changed to initialize
769 the type objects only once, even if the interpreter is initialized
770 multiple times.
771
Neal Norwitz61546162006-04-14 05:20:28 +0000772- Bug #1454485, array.array('u') could crash the interpreter. This was
773 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
774 to unicode when it didn't make sense. 'u#' now requires a unicode string.
775
776- Py_UNICODE is unsigned. It was always documented as unsigned, but
777 due to a bug had a signed value in previous versions.
778
Tim Peters3a5e8b12006-04-11 01:44:07 +0000779- Patch #837242: ``id()`` of any Python object always gives a positive
780 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
781 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000782 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000783 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000784
Tim Peters3a5e8b12006-04-11 01:44:07 +0000785 def __hash__(self):
786 return id(self) # WRONG
787
788 because a hash result must be a (short) Python int but it was always
789 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000790 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000791 was always usable as a hash value before this patch. That's no longer
792 necessarily so.
793
794- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000795 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000796 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000797 #1454844)
798
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000799- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
800 involving generators that have paused outside of any ``try`` or ``with``
801 blocks. (In 2.5a1, a paused generator that was part of a reference
802 cycle could not be garbage collected, regardless of whether it was
803 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000805Extension Modules
806-----------------

809 is a macro.
810
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000811- Bug #1467952: os.listdir() now correctly raises an error if readdir()
812 fails with an error condition.
813
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000814- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
815
816- Bug #1117761: bsddb.*open() no longer raises an exception when using
817 the cachesize parameter.
818
819- Bug #1149413: bsddb.*open() no longer raises an exception when using
820 a temporary db (file=None) with the 'n' flag to truncate on open.
821
822- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
823 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000824
Armin Rigoa9017c32006-04-19 11:50:27 +0000825- Patch #1062014: AF_UNIX sockets under Linux have a special
826 abstract namespace that is now fully supported.
827
Anthony Baxter51bcb682006-04-05 14:51:42 +0000828Library
829-------
830
Peter Astrand7d1d4362006-07-14 14:04:45 +0000831- Bug #1223937: subprocess.CalledProcessError reports the exit status
832 of the process using the returncode attribute, instead of
833 abusing errno.
834
Tim Peters711bf302006-04-25 03:31:36 +0000835- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
836 a doctest to be skipped (the code is not run, and the expected output
837 or exception is ignored).
838
Nick Coghlanda2268f2006-04-24 04:37:15 +0000839- Fixed contextlib.nested to cope with exceptions being raised and
840 caught inside exit handlers.
841
Greg Wardab05edc2006-04-23 03:47:58 +0000842- Updated optparse module to Optik 1.5.1 (allow numeric constants in
843 hex, octal, or binary; add ``append_const`` action; keep going if
844 gettext cannot be imported; added ``OptionParser.destroy()`` method;
845 added ``epilog`` for better help generation).
846
Tim Peters21fbd572006-04-21 21:18:10 +0000847- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
848 called from a thread spawned as a side effect of importing a module.
849
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000850- The pydoc module now supports documenting packages contained in
851 .zip or .egg files.
852
853- The pkgutil module now has several new utility functions, such
854 as ``walk_packages()`` to support working with packages that are either
855 in the filesystem or zip files.
856
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000857- The mailbox module can now modify and delete messages from
858 mailboxes, in addition to simply reading them. Thanks to Gregory
859 K. Johnson for writing the code, and to the 2005 Google Summer of
860 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000861
Tim Petersc7605f22006-04-17 21:12:33 +0000862- The ``__del__`` method of class ``local`` in module ``_threading_local``
863 returned before accomplishing any of its intended cleanup.
864
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000865- Patch #790710: Add breakpoint command lists in pdb.
866
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000867- Patch #1063914: Add Tkinter.Misc.clipboard_get().

870
Anthony Baxtere29002c2006-04-12 12:07:31 +0000871- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
872 Windows. Bug #1469163.
873
Phillip J. Eby47032112006-04-11 01:07:43 +0000874- The warnings, linecache, inspect, traceback, site, and doctest modules
875 were updated to work correctly with modules imported from zipfiles or
876 via other PEP 302 __loader__ objects.
877
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000878- Patch #1467770: Reduce usage of subprocess._active to processes which
879 the application hasn't waited on.
880
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000881- Patch #1462222: Fix Tix.Grid.

886 direct output to an alternate file-like object.
887

890
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000891- The Makefile now has a reindent target, which runs reindent.py on
892 the library.
893

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000898- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
899 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000900 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000901 CXX from --with-cxx-main, see description in README.
902
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000903- Patch #1429775: Link extension modules with the shared libpython.

906
Tim Peters8931ff12006-05-13 23:28:20 +0000907- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
908 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
909 and "%zu" for unsigned integers of type ``size_t``.

913
Nick Coghlanda2268f2006-04-24 04:37:15 +0000914- test_contextlib now checks contextlib.nested can cope with exceptions
915 being raised and caught inside exit handlers.
916
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000917- test_cmd_line now checks operation of the -m and -c command switches
918
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000919- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
920 it separately and by hand. It also wasn't cleaning up its changes to
921 the current Decimal context.
922
Thomas Woutersabd08882006-04-26 15:53:30 +0000923- regrtest.py now has a -M option to run tests that test the new limits of
924 containers, on 64-bit architectures. Running these tests is only sensible
925 on 64-bit machines with more than two gigabytes of memory. The argument
926 passed is the maximum amount of memory for the tests to use.

Tim Petersb06d28c2006-05-12 01:57:59 +0000937- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
938
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000939- PEP 343: Added Context Types section to the library reference

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000952Core and builtins
953-----------------
954
Nick Coghlan43832302006-04-23 17:04:07 +0000955- PEP 338: -m command line switch now delegates to runpy.run_module
956 allowing it to support modules in packages and zipfiles
957
Martin v. Löwisc661b882006-04-20 04:54:23 +0000958- On Windows, .DLL is not an accepted file name extension for
959 extension modules anymore; extensions are only found if they
960 end in .PYD.
961
Martin v. Löwisea62d252006-04-03 10:56:49 +0000962- Bug #1421664: sys.stderr.encoding is now set to the same value as
963 sys.stdout.encoding.
964
Neal Norwitz92e212f2006-04-03 04:48:37 +0000965- __import__ accepts keyword arguments.
966
Georg Brandlccadf842006-03-31 18:54:53 +0000967- Patch #1460496: round() now accepts keyword arguments.
968
Anthony Baxter262c00a2006-03-30 10:53:17 +0000969- Fixed bug #1459029 - unicode reprs were double-escaped.
970
Hye-Shik Changd478f342006-03-23 12:32:36 +0000971- Patch #1396919: The system scope threads are reenabled on FreeBSD
972 5.4 and later versions.
973
Neal Norwitze98ccf62006-03-23 05:39:47 +0000974- Bug #1115379: Compiling a Unicode string with an encoding declaration
975 now gives a SyntaxError.
976
Georg Brandlabd1ff82006-03-18 07:59:59 +0000977- Previously, Python code had no easy way to access the contents of a
978 cell object. Now, a ``cell_contents`` attribute has been added
979 (closes patch #1170323).
980
Tim Peterscf79aac2006-03-16 01:14:46 +0000981- Patch #1123430: Python's small-object allocator now returns an arena to
982 the system ``free()`` when all memory within an arena becomes unused
983 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
984 freed. Some applications will see a drop in virtual memory size now,
985 especially long-running applications that, from time to time, temporarily
986 use a large number of small objects. Note that when Python returns an
987 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000988 platform C library will in turn return that memory to the operating system.
989 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000990 appears to be effective at least on Microsoft C and gcc-based systems.
991 Thanks to Evan Jones for hard work and patience.
992
Georg Brandl533ff6f2006-03-08 18:09:27 +0000993- Patch #1434038: property() now uses the getter's docstring if there is
994 no "doc" argument given. This makes it possible to legitimately use
995 property() as a decorator to produce a read-only property.
996
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000997- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
998 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
999 of requiring an int or long in slicing and a few other contexts, enabling
1000 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1001
Neal Norwitz995acdf2006-03-07 05:01:00 +00001002- Fixed various bugs reported by Coverity's Prevent tool.
1003
Brett Cannonbf364092006-03-01 04:25:17 +00001004- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1005 new exception base class, BaseException, which has a new message attribute.
1006 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1007 Raising a string exception now raises a DeprecationWarning.
1008
Thomas Woutersfb609f42006-02-28 16:37:25 +00001009- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1010 explicitly relative, using 'from .module import name' to mean 'from the same
1011 package as this module is in. Imports without dots still default to the
1012 old relative-then-absolute, unless 'from __future__ import
1013 absolute_import' is used.
1014
Brett Cannona7446e32006-02-27 23:39:10 +00001015- Properly check if 'warnings' raises an exception (usually when a filter set
1016 to "error" is triggered) when raising a warning for raising string
1017 exceptions.
1018
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001019- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001020 The name was removed from Include/code.h.
1021
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001022- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001023
Guido van Rossum1968ad32006-02-25 22:38:04 +00001024- Patch 1433928:
1025 - The copy module now "copies" function objects (as atomic objects).
1026 - dict.__getitem__ now looks for a __missing__ hook before raising
1027 KeyError.
1028
Tim Peters84ef21c2006-02-28 20:39:06 +00001029- PEP 343: with statement implemented. Needs ``from __future__ import
1030 with_statement``. Use of 'with' as a variable will generate a warning.
1031 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001032 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001033 The following objects have __context__ methods:
1034 - The built-in file type.
1035 - The thread.LockType type.
1036 - The following types defined by the threading module:
1037 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1038 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001039
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001040- Fix the encodings package codec search function to only search
1041 inside its own package. Fixes problem reported in patch #1433198.
1042
1043 Note: Codec packages should implement and register their own
1044 codec search function. PEP 100 has the details.
1045
Tim Peters9ea89d22006-06-04 03:26:02 +00001046- PEP 353: Using ``Py_ssize_t`` as the index type.
1047
1048- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1049 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1050 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1051 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1052 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001053
Neal Norwitzfc76d632006-01-10 06:03:13 +00001054- Patch #1400181, fix unicode string formatting to not use the locale.
1055 This is how string objects work. u'%f' could use , instead of .
1056 for the decimal point. Now both strings and unicode always use periods.
1057
Neal Norwitz671b9e32006-01-09 07:07:12 +00001058- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1059 configure would break checking curses.h.
1060
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001061- Bug #959576: The pwd module is now builtin. This allows Python to be
1062 built on UNIX platforms without $HOME set.
1063
Neal Norwitzc10978f2005-12-19 06:07:16 +00001064- Bug #1072182, fix some potential problems if characters are signed.
1065
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001066- Bug #889500, fix line number on SyntaxWarning for global declarations.
1067
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001068- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1069
Neal Norwitze7214a12005-12-18 05:03:17 +00001070- Support for converting hex strings to floats no longer works.
1071 This was not portable. float('0x3') now raises a ValueError.
1072
Barry Warsaw2a38a862005-12-18 01:27:35 +00001073- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001074 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001075 is now displayed in interactive prompt banner.
1076
Georg Brandlfa166682005-12-17 21:45:17 +00001077- Implementation of PEP 341 - Unification of try/except and try/finally.
1078 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001079 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001080
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001081- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1082 now encodes backslash correctly.
1083
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001084- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1085
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001086- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001087 and long longs.
1088
Neal Norwitz67715f02005-11-09 06:59:35 +00001089- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001090 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001091 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001092
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001093- Replaced most Unicode charmap codecs with new ones using the
1094 new Unicode translate string feature in the builtin charmap
1095 codec; the codecs were created from the mapping tables available
1096 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1097 encodings now include a mapping for the Apple logo)
1098
Tim Peterse3547fd2005-12-16 23:13:57 +00001099- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001100
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001101- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001102
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001103- A new AST parser implementation was completed. The abstract
1104 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001105 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001106
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001107- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001108 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1109
Neal Norwitz708e51a2005-10-03 04:48:15 +00001110- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1111
Neal Norwitz11bd1192005-10-03 00:54:56 +00001112- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1113 Provide a warning when a directory is passed on the command line.
1114
Neal Norwitz40d37812005-10-02 01:48:49 +00001115- Fix segfault with invalid coding.
1116
1117- SF bug #772896: unknown encoding results in MemoryError.
1118
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001119- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001120 supported a __len__() method which evaluated to False when the iterator
1121 was empty.
1122
Guido van Rossum630db602005-09-20 18:49:54 +00001123- On 64-bit platforms, when __len__() returns a value that cannot be
1124 represented as a C int, raise OverflowError.
1125
Skip Montanarof8948ca2005-09-19 03:54:46 +00001126- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001127 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001128
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001129- SF bug #893549: parsing keyword arguments was broken with a few format
1130 codes.
1131
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001132- Changes donated by Elemental Security to make it work on AIX 5.3
1133 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1134 bug #105470: test_pwd fails on 64bit system (Opteron).
1135
Guido van Rossum539c6622005-09-14 17:49:54 +00001136- Changes donated by Elemental Security to make it work on HP-UX 11 on
1137 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1138
Georg Brandl4550b8d2005-08-26 06:43:52 +00001139- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001140 (fixes bug #1119418).
1141
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001142- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1143
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001144- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1145 exceptions that cause a function to exit.
1146
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001147- The implementation of set() and frozenset() was revised to use its
1148 own internal data structure. Memory consumption is reduced by 1/3
1149 and there are modest speed-ups as well. The API is unchanged.
1150
Tim Petersde7990b2005-07-17 23:45:23 +00001151- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1152
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001153- SF bug #1229429: PyObject_CallMethod failed to decrement some
1154 reference counts in some error exit cases.
1155
Tim Petersecc6e6a2005-07-10 22:30:55 +00001156- SF bug #1185883: Python's small-object memory allocator took over
1157 a block managed by the platform C library whenever a realloc specified
1158 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001159 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001160 portable way to copy data from the C-managed block into Python's
1161 small-object space without risking a memory fault. Python's small-object
1162 realloc now leaves such blocks under the control of the platform C
1163 realloc.
1164
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001165- SF bug #1232517: An overflow error was not detected properly when
1166 attempting to convert a large float to an int in os.utime().
1167
Raymond Hettinger3296e692005-06-29 23:29:56 +00001168- SF bug #1224347: hex longs now print with lowercase letters just
1169 like their int counterparts.
1170
Michael W. Hudson188d4362005-06-20 16:52:57 +00001171- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1172 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1173 interpreter states; back out that fix and do a better job (see
1174 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1175 for a longer write-up of the problem).
1176
Michael W. Hudsondf888462005-06-03 14:41:55 +00001177- SF patch #1180995: marshal now uses a binary format by default when
1178 serializing floats.
1179
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001180- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1181 the routines that promise to produce IEEE 754 binary representations
1182 of floats now simply copy bytes around.
1183
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001184- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1185 278.
1186
Brett Cannonc3647ac2005-04-26 03:45:26 +00001187- patch #1109424: int, long, float, complex, and unicode now check for the
1188 proper magic slot for type conversions when subclassed. Previously the
1189 magic slot was ignored during conversion. Semantics now match the way
1190 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001191 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001192 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001193 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001194
Barry Warsawc8d907c2005-04-19 23:43:40 +00001195- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1196 NULL, now raise an AttributeError when attempting to set or delete the
1197 attribute. Previously a TypeError was raised, but this was inconsistent
1198 with the equivalent pure-Python implementation.
1199
Michael W. Hudson774479c2005-04-18 08:46:17 +00001200- It is now safe to call PyGILState_Release() before
1201 PyEval_InitThreads() (note that if there is reason to believe there
1202 are multiple threads around you still must call PyEval_InitThreads()
1203 before using the Python API; this fix is for extension modules that
1204 have no way of knowing if Python is multi-threaded yet).
1205
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001206- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1207 disabled caused a crash.
1208
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001209- Bug #1165306: instancemethod_new allowed the creation of a method
1210 with im_class == im_self == NULL, which caused a crash when called.
1211
Tim Petersecc6e6a2005-07-10 22:30:55 +00001212- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001213 fixes the crash seen in bug #1165761
1214
Raymond Hettinger96229b12005-03-11 06:49:40 +00001215- Added two new builtins, any() and all().

Jeremy Hyltonab630502005-02-04 18:44:06 +00001249- The parser did not complain about future statements in illegal

1254 unicode instance if the argument is not an instance of basestring and
1255 calling __str__ on the argument returns a unicode instance.
1256
Tim Petersf4e69282006-02-27 17:15:31 +00001257- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1258 current thread state when the auto-GIL-state machinery knows about
1259 it (since the thread state is being deleted, continuing to remember it
1260 can't help, but can hurt if another thread happens to get created with
1261 the same thread id).

Nick Coghlan43832302006-04-23 17:04:07 +00001457- PEP 338: new module runpy defines a run_module function to support
1458 executing modules which provide access to source code or a code object
1459 via the PEP 302 import mechanisms.
1460

1469 in attribute values.
1470
Anthony Baxterc51ee692006-04-01 00:57:31 +00001471- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001472 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001473 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001474 module will not be built.
1475
Tim Petersc17976e2006-04-01 00:26:53 +00001476- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1477 aren't officially supported here, and trying to use them will probably
1478 raise an exception some day. But dicts have been allowed, and "mostly
1479 worked", so support for them won't go away without warning.

1499
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001500- email 4.0 package now integrated. This is largely the same as the email 3.0
1501 package that was included in Python 2.3, except that PEP 8 module names are
1502 now used (e.g. mail.message instead of email.Message). The MIME classes
1503 have been moved to a subpackage (e.g. email.mime.text instead of
1504 email.MIMEText). The old names are still supported for now. Several
1505 deprecated Message methods have been removed and lots of bugs have been
1506 fixed. More details can be found in the email package documentation.

1509 (a subclass of tuple) that provides incremental decoders and encoders
1510 (a way to use stateful codecs without the stream API). Python functions
1511 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1512 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1513 have been added.

1516 a ValueError instead of a StopIteration now (like file and cString.String do).
1517 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1518 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00001592 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1593 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1594 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1595 Ronald L. Rivest offered this advice for Python:
1596
1597 "The consensus of researchers in this area (at least as
1598 expressed at the NIST Hash Function Workshop 10/31/05),
1599 is that SHA-256 is a good choice for the time being, but
1600 that research should continue, and other alternatives may
1601 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001602

1759
Raymond Hettingerbab41432005-02-05 01:31:19 +00001760- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1761
Guido van Rossumd0641422005-02-03 15:01:24 +00001762- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1763 disables recursive traversal through instance attributes, which can
1764 be exploited in various ways.
1765
Tim Peterse3547fd2005-12-16 23:13:57 +00001766- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001767 flags on the HTTP listening socket.
1768
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001769- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1770 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1771
Fred Drakefbdeaad2006-07-29 16:56:15 +00001772- Patches #893642, #1039083: add allow_none, encoding arguments to
1773 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.

1778
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001779- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1780
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001781- Enhancements to the csv module:
1782
1783 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001784 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001785 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001786 + Dialect parameter parsing has been re-implemented to improve error
1787 reporting.
1788 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1789 dictates.
1790 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001791 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001792 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001793 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1794 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001795 + reader now allows \r characters to be quoted (previously it only allowed
1796 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001797 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001798 + Dialect classes passed to the module are no longer instantiated by
1799 the module before being parsed (the former validation scheme required
1800 this, but the mechanism was unreliable).
1801 + The dialect registry now contains instances of the internal
1802 C-coded dialect type, rather than references to python objects.
1803 + the internal c-coded dialect type is now immutable.
1804 + register_dialect now accepts the same keyword dialect specifications
1805 as the reader and writer, allowing the user to register dialects
1806 without first creating a dialect class.
1807 + a configurable limit to the size of parsed fields has been added -
1808 previously, an unmatched quote character could result in the entire
1809 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001810 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001811 the parser field size limit (returning the former limit). The initial
1812 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001813 + A line_num attribute has been added to the reader object, which tracks
1814 the number of lines read from the source iterator. This is not
1815 the same as the number of records returned, as records can span
1816 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001817 + reader and writer objects were not being registered with the cyclic-GC.
1818 This has been fixed.
1819
Brett Cannone6539c42005-01-08 02:43:53 +00001820- _DummyThread objects in the threading module now delete self.__block that is
1821 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1822 lock primitives tend to be limited in number and thus should not be wasted on
1823 a _DummyThread object. Fixes bug #1089632.
1824
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001825- The imghdr module now detects Exif files.
1826
Raymond Hettinger6065d322004-12-20 23:51:53 +00001827- StringIO.truncate() now correctly adjusts the size attribute.
1828 (Bug #951915).
1829
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001830- locale.py now uses an updated locale alias table (built using
1831 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1832 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001833 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001834
Raymond Hettinger3557f422004-12-07 12:02:02 +00001835- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1836
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001837- the pickle module no longer accepts the deprecated None option in the
1838 args tuple returned by __reduce__().
1839
Brett Cannon84667c02004-12-07 03:25:18 +00001840- optparse now optionally imports gettext. This allows its use in setup.py.
1841
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001842- the pickle module no longer uses the deprecated bin parameter.
1843
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001844- the shelve module no longer uses the deprecated binary parameter.
1845
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001846- the pstats module no longer uses the deprecated ignore() method.
1847
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001848- the filecmp module no longer uses the deprecated use_statcache argument.
1849
Raymond Hettinger664347b2004-12-04 21:21:53 +00001850- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1851 extended or overridden by subclasses. Formerly, the subclassed method would
1852 be ignored by the rest of the module. (Bug #1078905).
1853
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001854- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001855 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001856
Walter Dörwald36733692004-12-22 12:50:50 +00001857- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1858 once when a size argument is given. This prevents a buffer overflow in the
1859 tokenizer with very long source lines.
1860
Barry Warsaw538561e2006-01-01 21:48:54 +00001861- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1862 immediately after creating the object, without any intervening
1863 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001864
Skip Montanaro05885812005-01-16 20:48:27 +00001865- The reconvert.quote function can now emit triple-quoted strings. The
1866 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001867
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001868- ``UserString.MutableString`` now supports negative indices in
1869 ``__setitem__`` and ``__delitem__``
1870
Greg Ward40407942005-03-05 02:53:17 +00001871- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1872 correctly.
1873
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001874- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1875 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1876 character even if the user has passed a size parameter to get a proper
1877 line ending. Remove the special handling of a "\r\n" that has been split
1878 between two lines.
1879
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001880- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1881 about illegal code points. The codec now supports PEP 293 style error
1882 handlers.
1883
Walter Dörwald78a78b02005-09-01 12:04:29 +00001884- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001885 from the input stream, so that the output is a byte string in the correct
1886 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001887
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001888- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1889 considering it exactly like a '*'.
1890
Walter Dörwald007f8df2005-10-09 19:42:27 +00001891- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1892 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001893
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001894- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1895
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001896- Patch #1413711: Certain patterns of differences were making difflib
1897 touch the recursion limit.
1898
Walter Dörwald58917a62006-03-31 15:26:22 +00001899- Bug #947906: An object oriented interface has been added to the calendar
1900 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001901 called as a script (e.g. via ``python -mcalendar``). Localized month and
1902 weekday names can be ouput (even if an exotic encoding is used) using
1903 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001904
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001905Build

1907
Neal Norwitz602d3392006-03-31 08:21:40 +00001908- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1909 by using -mieee gcc option.
1910

1912
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001913- Build support for Win64-AMD64 was added.
1914
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001915- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1916
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001917- Patch #881820: look for openpty and forkpty also in libbsd.
1918
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001919- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1920 The zlib module is now builtin on Windows.
1921
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001922- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1923
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001924- Bug #1189330: configure did not correctly determine the necessary
1925 value of LINKCC if python was built with GCC 4.0.
1926
Trent Mick8321b422005-07-26 02:29:21 +00001927- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1928 vulnerability in zlib 1.2.1 and 1.2.2.
1929
Brett Cannon08cd5982005-04-24 22:26:38 +00001930- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1931 flags that change binary compatibility. Changes were also made to
1932 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001933 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001934
Bob Ippolitoed233462005-03-29 13:47:59 +00001935- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1936 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1937 no longer exists). This configure patch makes things right.
1938
Martin v. Löwise2713be2005-03-08 15:03:08 +00001939- Bug #1158607: Build with --disable-unicode again.
1940
Brett Cannon46d96232005-02-16 00:07:19 +00001941- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1942 defined. Discovered as a result of not being able to build on OS X.
1943
Brett Cannon516592f2004-12-07 00:42:59 +00001944- setup.py now uses the directories specified in LDFLAGS using the -L option
1945 and in CPPFLAGS using the -I option for adding library and include
1946 directories, respectively, for compiling extension modules against. This has
1947 led to the core being compiled using the values in CPPFLAGS. It also removes
1948 the need for the special-casing of both DarwinPorts and Fink for darwin since
1949 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1950 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1951 Fink, ``-I/opt/local/include`` for DarwinPorts).
1952
Brett Cannon43802422005-02-10 20:48:03 +00001953- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1954 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1955 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1956 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001958C API
1959-----
1960
Tim Petersc9d78aa2006-03-26 23:27:58 +00001961- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1962 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1963 is obtained via the ``PyObject_`` family, it must be released via the
1964 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1965 always been officially true, but when Python's small-object allocator was
1966 introduced, an attempt was made to cater to a few extension modules
1967 discovered at the time that obtained memory via ``PyObject_New`` but
1968 released it via ``PyMem_DEL``. It's years later, and if such code still
1969 exists it will fail now (probably with segfaults, but calling wrong
1970 low-level memory management functions can yield many symptoms).
1971
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001972- Added a C API for set and frozenset objects.
1973
Raymond Hettinger66517482004-12-03 11:45:13 +00001974- Removed PyRange_New().
1975
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001976- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1977 mapping argument now. This string is used as a mapping table. Byte values
1978 greater than the length of the string and 0xFFFE are treated as undefined
1979 mappings.
